Before Ivey’s film, he pushed a popular science article on screen technology, which attracted everyone’s attention. Today, let’s pay attention to the "behind-the-scenes" that is related to the screening effect-the projector.

　

Film projectors have become a memory for most people, and today’s cinemas have already become the world of digital projectors. Let’s briefly talk about the development history of digital projectors.

Advances in chip technology and resolution

Digital film projectors can be divided into 4K, 2k and 1.3k (obsolete) according to the resolution from high to low, and the core part is the DLP chip.

　

The digital film projector that appeared at the end of last century and the beginning of this century is1.3K(1280×1024, about 1.3 million pixels) resolution.. Its architecture is a DLP projection system with a digital projector head in front of the light box of the traditional film projector, and its imaging device is the DLP CinemaTM DMD digital micromirror device of Texas Instruments (TI).

　

DP50 1.3K digital projector

DLP technology (digital light processing) is a technology developed by Texas Instruments based on DMD. DMD (digital micromirror) is also an imaging chip developed by TI, and it is also the core component of DLP. DMD consists of many small aluminum mirrors, and each micro mirror is called a pixel. Its working principle is that after receiving the image control signal, it drives the micro mirror to deflect within 15 degrees, reflects light, and finally forms an image. Digital film projectors and high-end projectors generally adopt RGB three-chip DLP technology.

　

With the development of chip technology,The first 2K (2048× 1080.21 million pixels)The projector came out at the end of 2003, which adopted the DC2K DLP CinemaTM DMD chip of TI company, which improved the image resolution and contrast. This eliminated the projector that originally used 1.3K chip.

　

DP100 and DP90 2K digital projectors

In 2005-2006, DCI (Digital Cinema Advocacy Organization) released the technical specification 1.0 of digital cinema system, and various digital cinema equipment manufacturers followed suit, and developed and produced projector products conforming to DCI technical specification. According to DCI standard, the pixels of digital cinema projectors should reach 2K or 4K. Projector manufacturer including DLP technology, Barco, CTV and NEC, as well as Sony adopt liquid crystal on silicon SXRD technology, have launched a series of products.

　

In 2009, TI released its second generation DLP digital film platform.DLP Cinema?　Series II (SII or Series 2 for short). S II not only supports all the functions of the previous generation SI platform, but also enhances the signal processing ability of the system, and conforms to the DCI Digital Cinema System Technical Specification 1.2 in application.

　

In 2011, based on DLP Cinema? 1.38 "(inches).DMD 4K chipThe resolution reached 4K (4096× 2160,825 million pixels). In addition, in order to meet the needs of more small screens, the advent of 0.69 "DMD2K chips based on DLP Cinema has led manufacturers to launch DLP large projectors and small projectors based on these chips. With the advent of DLP4K projector, digital projection is comparable to 35mm film projection in definition, and the overall projection visual effect is better.

　

2019 4K global blockbuster "Maleficent: Mistress of Evil"

In 2013, TI (Texas Instruments) DLP Products Division launched a new breakthrough pixel architecture for its leading DLP Pico? technology.TIlt Roll Pixel（TRP）. The main advantages of products based on the new TRP pixel architecture include:

Improve brightness by up to 30% and higher efficiency; Energy saving by reducing power consumption by up to 50%; Twice the resolution of chips of the same size, and so on. For example, the s4 series of Barco’s fourth-generation projector is the latest series of digital projector products that take the lead in adopting 3×0.98” DC4K TRP chip, which can save more energy and further improve the degree of integration.

Progress in architecture and automation

The innovation of digital projection technology makes the control of equipment more and more automatic and intelligent.

　

Due to high integration and strong sealing performance,Heat dissipation and dust preventionIt is the most difficult problem of projectors in the past. In the past, when solving these two problems, the projectionist was particularly required to maintain the projection equipment in peacetime, but with the upgrade of the projector, the handling of these two aspects has now become simpler and more convenient.

　

The heat dissipation of the projector mainly surrounds the light source, chip and circuit. These places are easy to accelerate aging or damage if the heat dissipation is not in place, and attention should be paid not to have any dust when cooling. For example, high-precision core components such as chips cannot be polluted by any dust.

　

Now there are several ways to cool the projector:Air cooling, liquid cooling, and semiconductor cooling.. Air cooling mainly depends on the cooling channel designed in the projector; Liquid cooling is mainly aimed at the internal heat dissipation of the engine, and there is a set of liquid cooling heat dissipation system composed of liquid tank, pressure pump and heat exchanger in the projector. Semiconductor cooling, like using "Peltier" thermoelectric semiconductor refrigeration device.

　

Barco s4 projector series inherits the consistently efficient integrated cooling system of liquid cooling+air cooling+Peltier, and with the fully enclosed engine and light path design, the new double-layer HEPA washable filter screen can achieve the ultimate dustproof and efficient cooling effect. At the same time, the modular design of S4 series and brand-new network control and analysis software make the daily maintenance and repair of projectors easy, which greatly reduces the labor cost of daily operation and maintenance.

　

In addition to the continuous improvement of automation level, the projector architecture is also constantly optimized. From the original independent external server to the integrated media module IMB, to today’s integrated media server with higher integration.IMSsSome even integrate audio decoding module, which has higher integration and improved performance.

　

For example, in March, 2014, Barco first launched a product equipped with Lingrui.ICMP(Integrated Cinema Media Processor integrated media module) integrated projector of server. The ICMP module of Barco Lingrui skillfully integrates the digital movie image signal processor (ICP) with the media server responsible for the decoding function of DCI movie programs, which improves the simplicity and reliability of the projector. Intelligent projectors equipped with Lingrui ICMP can even detect potential operational errors and warn users when potential failures occur.

　

ICMP server

The historical origin of digital projector from the initial independent external server to the integrated media module IMB to the integrated media server IMSs with higher integration now comes from the actual demand of the film industry for higher image quality, higher frame rate and higher resolution. In the technical field of projectors and media servers, this can be summarized as follows,Need to pass a higherbandwidthTo process and transmit image data. This has become the driving factor of digital projectors from independent servers to IMBs(Integrated Media Blocks) and then to IMSs (Integrated Media Server) from 2005 to 2012.

　

In addition, in recent years, digital projectors are constantly strengthening their targeting.Automatic maintenance and optimization technology of laser light source and automatic image optimization technologyWith the passage of time, the white balance of the three-color laser light source of the projector is guaranteed and the color reproduction is better; The final imaging quality of the optical engine has been kept at a good level for a long time.

Progress in technical indicators

The technical progress of projector naturally promotes the improvement of its related technical indicators, so as to adapt to the landing of new projection technology.

　

For example, adapting to high frame rate projection, adapting to HDR (high dynamic range) image optimization, etc., requires a higher projectorBrightness, contrast, clarity and high color depth processing circuit, at the same time haveHigh frame rate projectionFunction.

　

The 1.3k machine adopts the 1.1 "/0.9" (inch) DLP CinemaTM DMD chip of TI company, with the contrast ratio of 1350: 1 and the deflection angle of DMD micromirror of 10. The final light output is about 6,000-13,000 lumens, and its light efficiency is relatively low, with the average light path light efficiency of 1-2 lumens/watt. At first, the 1.3k machine can handle Bit depth.

　

The second generation projector chip (DC2K DMD chip) comes in 1.2 "(inch) and 0.98" (inch), which were released by TI in 2003 and 2007 respectively. Compared with the 1.3 K chip, DC2K DMD chip increases the deflection angle of DMD micromirror by 12, making its contrast ratio more than 2000∶1. The light output of 2K projector can reach 30,000 lumens, and the color depth can reach 15 bits ×3. Moreover, the support for secure encryption/decryption, from supporting Cine I to supporting Cine II, meets the strict requirements of digital cinema for content security protection.

The 4K digital projector based on DLP Cinema? 1.38 "(inch) DMD chip has a brightness of 32,000 lumens and a contrast ratio of more than 2,100: 1.

　

S4 series projectors

Now the projector has a higher level of indicators. On BIRTV in 2020, Barco introduced the high-brightness RGB laser projector SP4K-40B with 40,000 lumens in the fourth-generation projector family, and introduced the RGB laser projector SP4K-55B with 52,000 lumens in CinemaS in 2021. In this fourth-generation projector family, the contrast ratio can reach 5,000: 1 like SP4K-27BHC.

　

In addition, with the improvement of light source, RGB laser projector has also improved the color range of the picture from DCI-P3 to.Rec2020, the color range is expanded by about.thirty percentFinally, due to the replacement of TI DLP technology, the fourth generation projector of Barco, which currently adopts the latest technology of TI, also has the ability to play.4K high frame rateThe ability of (high frame rate means > ＞24fps) greatly exceeds the original traditional signal format. Although there are not many such movies, the projector hardware is still ahead.

　

It can be said that the projection visual effect provided by the current digital projector has far exceeded the film projector era, providing a better viewing experience to a greater extent, and at the same time bringing higher intelligent automation to the operation, use and maintenance optimization of the cinema, making the cinema have a wider choice for different screens, different technical requirements and automatic projection, and greatly enhancing the security of film copyright!

　　In our country, most urban communities are composed of closed communities composed of high-density assembled houses, and each community is inhabited by thousands or even tens of thousands of people. With the intensification of population mobility, the community composed of strangers is completely different from the traditional rural community, and it is also different from the unit compound based on colleague relationship. Here, the binding force of acquaintance social rules is greatly weakened, and the large-scale and high-density living style makes various contradictions and disputes increasingly high, and new governance mechanisms and models need to be established urgently.

　　It seems that all kinds of contradictions and disputes in the community are mostly small problems, but in fact, the small problems that have accumulated over time and repeatedly have had a great impact on the living quality and living standards of the people. At the moment when the city is pursuing connotative development and vigorously improving people’s sense of happiness and gain, the community where we live every day should not become a forgotten corner and let "wrangling" be staged from time to time.

　　To this end, the editorial department of the semi-monthly talk organized reporters to go to Sichuan, Hainan, Jiangxi, Yunnan and other places to conduct research from three dimensions: residents and property, residents and community services, and sort out three major dilemmas: unbalanced rights, out-of-control disputes and service disability, which will serve as a pulse for the management of residential quarters.

　　Thematic planning and editing: Yuan Bixia Xu Xicai

　　The dilemma of "three lost" in urban community — — Unbalanced rights: how can the owners win when fighting with the property?

　　Half-monthly talk with reporter Zhao Yeping, Lu You, Yi Xuru

　　Compared with organizations, individuals are always in a weak position. This is reflected in the contradictions in the community. Residents in the scattered community can’t have an equal dialogue with the property company at all, and some behaviors of the property company are obviously unreasonable, so they can only bear it. If this imbalance persists, some contradictions and disputes will accumulate, which may even lead to mass incidents.

　　"Buy a suite with your life savings, and then spend money on the property to toss yourself!" Some owners have issued such a sigh.

　　Property VS Residents: Highlighting Five Contradictory Focuses

　　In almost every community, there are contradictions between residents (including owners and tenants) and property in one way or another. According to the statistics of 12345 citizen service hotline in Haikou City, Hainan Province, in 2017 and 2018, the hotline complaint type data ranked first, and most disputes originated from inadequate community management and chaotic charges. Government departments spend a lot of administrative resources to deal with these disputes, but they often end up without results.

　　Half-monthly interviews with reporters found that the current contradiction between residential residents and property mainly focuses on the following aspects.

　　Focus 1: Property charges rise at will, and owners default from time to time.

　　Recently, a residential property company outside the South Fifth Ring Road in Beijing informed the owners that the property fee rose from 2.18 yuan to 2.68 yuan, which triggered some owners’ resistance. "The property company claimed that after telephone and household consultation, it reached a unified opinion with most owners, but in fact some owners did not know." The owner, Mr. Chen, said that the property also held a "revenue and expenditure briefing meeting", but the accounts were not audited by a third party and were unconvincing.

　　A property manager told a reporter who talked for half a month that property is a small profit industry. Many times, once the owner delays paying the property fee, it is easy to cause the enterprise to lose money. So sometimes, in order to ensure their own interests, some property companies will force owners to pay by stopping handling water and electricity bills.

　　Focus 2: Public infrastructure needs to be repaired and replaced, but the cost is unclear.

　　Since 2016, located in a residential area between the First Ring Road and the Second Ring Road in Chengdu, elevators often break down. In April this year, the property company in the residential area posted a notice saying that the property company had funded the maintenance of elevators for several years, and the maintenance cost reached 425,000 yuan. This news caused some owners to question. Liu Jiabin, deputy secretary of the Party branch of the community, told reporters in half a month that at that time, some owners felt that the maintenance fund of 971,000 yuan had been used in the past three years. Why did it generate more than 400,000 yuan in advance expenses?

　　Focus 3: Community public assets are abused for profit, and the income and expenditure are unknown.

　　There are some assets owned by the owners in the community, and property companies often use them to obtain income without the owners’ knowledge or consent, and the whereabouts of expenditures are unknown. Take advertising revenue as an example. Most of the light box advertising and elevator advertising resources in the community are sold by property companies to advertisers, but the revenue is rarely announced to the owners, and most owners don’t know where the revenue is used.

　　An owner of Lehuo Gongyuan City Community in Nanchang City, Jiangxi Province told reporters that there are 10 buildings in the community, each with two stairs and three billboards in each staircase. The owner directly removed the advertisement of the building where he lived, and the property was monitored to find the owner. The owner believes that the elevator is a public space and cannot be used for elevator advertising, and requires the property to announce the use of billboards. Finally, the property did not install billboards in this elevator, and never gave relevant financial information.

　　Focus 4: Parking charges are chaotic and management norms can’t keep up.

　　With the popularization of urban cars, parking spaces are becoming scarce resources. In many cities across the country, such as Beijing, Shanghai and Chengdu, it is not uncommon for some property companies to raise the price of parking spaces at will. Disputes caused by parking chaos and parking difficulties are staged almost every day in some communities. "There are always other people’s cars parked in the parking spaces that my family pays for." Mr. He, who lives in Binjiang Community, Hanzhong City, Shaanxi Province, said, "The property always says that it should be standardized, but there has been no movement."

　　Focus 5: The collection of water and electricity charges failed to facilitate the people, but instead "pitted the people".

　　In some communities, residents’ utilities are collected by the property, which is a good thing for the convenience of the people. However, due to management loopholes or abuse of charging power in some property companies, many disputes have arisen.

　　Xin Chen, director of the industry committee of Fuxiang Jiayuan Community, Haikou City, Hainan Province, still remembers that once the property management company of the community used the water and electricity fees paid by the owners to pay their employees, and the water supply company and power supply bureau that were owed water and electricity fees often "stopped supplying water" and "cut off electricity" to the community, so the owners had to stay in hotels in married with children. Some owners who know what happened blocked the door of the community and refused to let the property manager leave, "forcing" him to solve the problem.

　　The establishment of the operation industry Committee faces

　　"eighty-one difficult"

　　Why are contradictions and disputes frequent? Insiders and grassroots cadres believe that the fundamental reason lies in the imbalance of rights between property and owners. Without an effective owners’ meeting and industry Committee, the owners are like a mess. Hiring a property company, dealing with the relationship with neighborhood committees and protecting the rights and interests of owners are all difficult to express their opinions, and there is also a lack of channels and platforms to solve problems.

　　According to a survey conducted by reporters in the past two months, although property management measures have been introduced in various places in recent years to encourage the establishment of industry committees in residential quarters, many industry committees in residential quarters have suffered from "dystocia" or even "abortion" due to the unfamiliar policies of owners, contradictions between owners and property companies, low social trust of strangers, and too complicated establishment procedures. Under the game of interests of all parties, the establishment of operation committee is facing the "eighty-one difficult".

　　According to Article 12 of the Regulations on Property Management in the State Council, the formulation and revision of the rules of procedure of the owners’ congress, the election of the owners’ committee or the replacement of the members of the owners’ committee, the selection and dismissal of property service enterprises, etc. shall be subject to the consent of the owners who account for more than half of the total building area and more than half of the total number.

　　"Hundreds of households and thousands of households should reach ‘ Double half ’ (More than half of the area and more than half of the owners) is very difficult. " Xiao Jiangtao, president of Haikou Owners’ Committee Association, said that some communities in Haikou have struggled for nearly 10 years and failed to set up industry committees.

　　According to reports, the proportion of the establishment of the industry Committee in Haikou Community is only 13.4%, and the proportion of the establishment of the national community industry Committee is not high, and the proportion in Beijing is only 25%.

　　Xiao Jiangtao believes that the deep-seated reason for the difficulty in the establishment and operation of the industry Committee is that the competent government departments are unwilling to intervene, do not know how to intervene, and have no ability to intervene.

　　According to an industry insider, according to the current law, street offices and township governments have the responsibility of guiding and supervising the establishment of industry committees in communities, but in fact, guidance and supervision have become examination and approval. Because this work is not linked to the political achievements of streets and towns, it can be done or not, and it is thankless, so it often becomes resistance rather than help.

　　In addition to being unwilling to guide and supervise, the competent government departments still have the problem of being unable to guide and supervise. Take Haikou as an example, there are 4 people in the Property Department of the Housing and Construction Bureau of Haikou City, and one deputy director of the residential insurance center in each district is in charge of the property. There are dozens of communities in each district, and there are no full-time property management personnel in the street office.

　　"The community only maintains stability, and it doesn’t matter if it doesn’t go wrong." A person in charge of the community industry Committee said that the neighborhood Committee will come forward to repair the road water in the village, but the road water in the community can only be responsible by the community itself. In 2018, the community built a cultural and sports activity center, and the industry Committee didn’t have enough funds, so it sent representatives to the neighborhood Committee and the street office to apply. The answer was: "How are you qualified to come to us for money?"

　　Owners "fight alone" when preparing for the establishment of the industry committee. After the establishment, the industry committee is still "fighting alone". How to negotiate with the property company and how to formulate the rules of procedure are all left to the members of the industry committee to explore. Those with strong ability will be handled well, while those with poor ability will often be "criticized" by the owners. As volunteers, the members of the industry committee serve the community free of charge and are under great physical and mental pressure.

　　Xiao Jiangtao said that the main reason why it is difficult to establish and carry out the work of the industry committee is that the industry committee is a new thing, and China’s commercial housing has only developed for more than 20 years now. "As an individual, the owners now have to work with corporate enterprises such as property and developers ‘ Fight for benefits ’ , even if it is the interests that originally belonged to the owner, it was strongly attacked because it broke the previous interest circle ‘ Fight back ’ 。” (Participating in writing: Yao Ziyun)

1905 movie network news Recently, the new film UGLYDOLLS, which was filmed by kelly asbury and co-director, exposed the posters of the characters. On the poster, this group of ugly and ugly little dolls made an incomparable appearance, which was very interesting.

　

Warm color matching, cute modeling, and cute movements all make people laugh. At present, the plot of the film has not been revealed, except that it is an animated film, mainly for the whole family, teenagers and women around the age of 20. This Chinese name will be used in movies, dramas and derivatives, please measure it comprehensively. As the first part of the series, this film tells the story of a group of dolls with strange looks. In order to pursue their dreams, they go to the perfect world and prove that they can achieve their wishes by being brave and true, and they are loved by people.

　

Uglydoll’s idea originated from two lovers of new york Art Institute. After the September 11th incident, Kim Sang-min from South Korea had to return to South Korea, and David Howens, who was far away in new york, missed him. So David Howens began to write to Kim Sang Min. In the letter, I will draw a little monster named Wage to amuse my girlfriend. Wage is an orange monster who wears an apron and works hard. One Christmas, Jin Sangmin sewed Wage into a doll and called it "Uglydoll", so the first Uglydoll was born. In the following years, Uglydoll has gradually developed into a big family, and has its own original cartoons, short films and puppets.

　

At present, the film is scheduled to be released on May 10, 2019, and the trailer will be released this week.

The "Good Bad Review" option is juxtaposed with "Online Application, Online Appointment, Online Consultation" and so on.

The evaluation level of "good bad review" is divided into five.

On October 28th, Wang Yi, a lawyer assistant in a law firm in Chengdu, opened a web browser, entered the keyword "Sichuan Government Service Network", entered the home page, found the online service window she needed in the "Personal Service-Professional Qualification" option, and immediately completed an application.

After some operation, Wang Yi’s working experience was excellent. She chose the smiling face pattern in the column of "Good Bad Review" to draw a satisfactory conclusion for this online work.

Wang Yi is an early adopter who holds a "power bar" with good and bad reviews. On the same day, Sichuan launched the "Good Bad Review" platform for government services. In the future, every user can play "good review" or "bad review" for the experience of government services like Wang Yi.

All service matters are included in the evaluation scope.

"This is an all-round revision." The person in charge of the relevant departments of the general office of the provincial government summed it up. He introduced, "The upgraded Sichuan government service network integrates seven major sections, such as’ home page, personal service, corporate service, direct access to cities and states, direct access to departments, interaction between the government and the people, and openness of government affairs’, and realizes five services, such as’ event service, identity authentication, payment service, license service and good and bad reviews’."

Among them, the new "good bad review" platform has attracted much attention. The person in charge said that in order to implement the requirement of establishing a "good bad review" system for government services in Premier Li Keqiang’s "Government Work Report" in 2019, Sichuan has specially issued a "Work Plan on Establishing a" good bad review "system for government services" in light of the actual situation, and formulated an overall "good bad review" action plan for the whole province. "The government service network has a’ good bad review’ area, which means that users can make an outspoken evaluation of the satisfaction of government services like online shopping. Whether it is praise or spit, or make comments and suggestions. "

On the network platform of "Sichuan Provincial Government Service Network", we can see that the administrative license, administrative payment, administrative confirmation, administrative ruling, administrative reward, and the handling of the people on the 12345 hotline have all been included in the evaluation scope of "good and bad reviews". The options of "Good Bad Review" and "Online Application", "Online Appointment" and "Online Consultation" are listed in the service options column.

Full coverage of online and offline "good bad reviews"

In the eyes of the experiencer Wang Yi, the construction of the platform of "good bad reviews" is to actually hand over the "assessor" to test whether the client is satisfied. "What is the experience of the parties, and they have the most say."

According to the design, the evaluation level of "good bad reviews" is divided into five levels, namely, very satisfied, satisfied, basically satisfied, dissatisfied and very dissatisfied. Evaluation to take real-name registration system, enterprises and the masses every time for a government service matters, can be evaluated after the completion of a ..

According to the person in charge of the platform, it is a prominent feature of the platform to achieve full coverage of online and offline "good and bad reviews" channels. Among them, online evaluations include Sichuan government service network, Tianfu Tongban, WeChat applet, Alipay applet, etc. Offline evaluation includes evaluator, code scanning, SMS, self-service terminal, QR code, "12345" government service hotline, etc.

Take the online evaluation of Sichuan government affairs service network as an example. When the clerk wants to evaluate the completed documents, he can enter the user center, select "My Evaluation" and click "Documents to be evaluated" to evaluate the listed items. It is worth mentioning that the service object is not evaluated within 7 working days after receiving the service, and the system will evaluate it as "basically satisfied" by default.

"Bad review" object completes rectification within 15 days.

What’s the use after obtaining the evaluation results? The person in charge of the relevant departments of the general office of the provincial government responded that the "good bad review" platform aims to improve the quality of government services in the province and accelerate the creation of a market-oriented and legalized international business environment. If the "dissatisfied" or "very dissatisfied" evaluation items are found to be true, it is required to make rectification within 15 days, and the rectification results will be fed back to the evaluator through online government service platform, mobile user center and SMS.

For the incentive of "praise", it is clearly put forward that all relevant departments (units) in all parts of the province should link "praise" with the performance appraisal of units and individuals as an important content of target performance, annual assessment and advanced selection, and obviously increase the praise and incentive.

Editor Xu Tengfei proofreads Wang Xin.

Beijing, December 6 (Xinhua) The biggest highlight of this year’s medical insurance negotiations is the suspense brought by the participation of more than 20 domestic innovative drugs in the negotiations.

On December 3, the new medical insurance catalogue of the National Medical Insurance Bureau was officially released. Rongchang Bio, which promoted two "world-class domestic innovative drugs" independently developed at one time to the medical insurance catalogue, immediately became the focus.

Taita Xipu (trade name: Taiai? ), vidiximab (trade name: Aidixi? ) was conditionally approved for listing by National Medical Products Administration (NMPA) in March and June, 2021 respectively. The former is the world’s first "dual-target" biological new drug for the treatment of systemic lupus erythematosus, and the latter is the first original antibody-coupled (ADC) drug in China. It is these two innovative drugs that have been approved to enter the medical insurance catalogue this time.

In less than half a year, two world-class original new drugs have been approved for listing; Just a few months later, two new drugs entered the medical insurance catalogue at the same time. Rongchang Bio’s innovation ability, product quality and commercialization speed are once again presented.

China’s self-developed world-class new drug "quickly" reduced the price into medical insurance

Why do innovative drugs get attention when they enter the medical insurance catalogue? Because this means the opening of a new life channel for patients with corresponding indications. Pay a lower fee, use the world’s leading new drugs and good drugs, and stay away from "poor diseases".

In fact, according to preliminary estimates, the adjustment of the national medical insurance drug list in the past three years, compared with the pre-negotiation market price, has reduced the burden on patients by nearly 170 billion yuan and benefited 100 million patients through negotiation price reduction and medical insurance reimbursement.

"The two pioneering new drugs, Taitacip and Vidicotuzumab, are quickly reduced in price into medical insurance, which can improve the accessibility of these two world-class biological new drugs in the country, help China’s over one million patients with systemic lupus erythematosus and the vast number of patients with gastric cancer to get effective treatment, reduce the economic burden of patients and their families, and better play the social benefits of drugs." Dr. Fang Jianmin, CEO and chief scientific officer of Rongchang Bio, said.

Systemic lupus erythematosus patients and other first domestic innovative drugs.

Systemic Lupus Erythematosus (SLE) is a lifelong systemic immune disease, which can cause damage to kidneys, cardiovascular system, lungs, digestive system, blood system, blood vessels, eyes and other organs and tissues, and significantly increase the risk of death of patients. Its harm makes people talk about it. According to "Guidelines for Diagnosis and Treatment of Systemic Lupus Erythematosus in China in 2020", there are more than 1 million patients with systemic lupus erythematosus in Chinese mainland, and the prevalence rate is the second highest in the world.

However, for a long time, a large group of patients have been faced with the dilemma of drug use-traditional glucocorticoids, immunosuppressants, etc. are often accompanied by great toxic and side effects, which are unbearable for patients. At the same time, it is difficult to "breed" new therapeutic drugs. In the past 60 years, the US Food and Drug Administration (FDA) only approved a drug for the treatment of systemic lupus erythematosus in 2011 (Berizumab developed by GlaxoSmithKline).

Rongchang Bio was included in the national medical insurance drug list this time, which is tetasip for injection (specification: 80mg/ piece). It is the first innovative drug approved in the treatment of systemic lupus erythematosus in China, and it is also the first-in-class biological drug in the world.

Different from the single-target design of listed drugs, the "double-target" design of Tatasip can inhibit BLyS and APRIL, two key factors that make B lymphocytes differentiate and mature at the same time, which can reduce the immune response of the body more effectively and play a "two-pronged" effect on treatment. The key clinical data showed that the systemic lupus erythematosus response index (SRI) in the high-dose group was significantly higher than that in the placebo control group (79.2% vs 32.0%) after 48 weeks of treatment, and the improvement of SRI was significantly better than that of the new biological drugs currently on the market. At the same time, the macromolecular drug Tetasip can be metabolized directly through cells, instead of liver and kidney metabolism, which can significantly reduce the side effects of traditional drugs and has higher safety. In a word, as a new drug with new target, new structure and new mechanism, Tetasip brings infinite new hope to the global SLE medical field.

Professor Zhang Fengchun, the head of clinical trial of Taitacip and the chief physician of Peking Union Medical College Hospital, said: "Compared with the existing treatment methods, the main therapeutic indexes of Taitacip have been greatly improved, which is a major breakthrough in the treatment of systemic lupus erythematosus, marking that China has taken the lead in the field of research and development of new drugs for the treatment of systemic lupus erythematosus. The inclusion of this drug in the national medical insurance drug list will further improve the accessibility of drugs, greatly reduce the medical burden of patients with systemic lupus erythematosus, and bring them higher quality survival benefits. "

Tetasip’s innovation has been recognized internationally, and its invention patents have been authorized by China, the United States, Europe and other countries and regions. Besides the indications of systemic lupus erythematosus, domestic and international clinical trials of Tatasip for neuromyelitis optica spectrum diseases, rheumatoid arthritis, IgA nephropathy, Sjogren’s syndrome, multiple sclerosis and myasthenia gravis are being conducted in an orderly manner.

To fill the blank of back-line therapy for gastric cancer patients with HER2 overexpression in China.

Another new drug of Rongchang Bio, which is included in the medical insurance catalogue, is vidiximab for injection (specification: 60mg/ piece), which is approved for patients with locally advanced or metastatic gastric cancer (including adenocarcinoma of gastroesophageal junction) who have received at least two systemic chemotherapy (HER2 immunohistochemical results are 2+ or 3+).

In China, gastric cancer is the second largest cancer species after lung cancer, with an annual incidence of 400,000, ranking first in the world. The morbidity and mortality are both high. 80% of patients with gastric cancer in China were in advanced stage when they were diagnosed. For most patients with advanced gastric cancer, chemotherapy is still the first choice for first-line treatment in the past few decades. However, the therapeutic effect of chemotherapy is limited, and the side effects are great, and the precise drugs for patients with gastric cancer who overexpress HER2 are even blank.

According to the latest data, the objective remission rate (ORR), disease control rate (DCR), median progression-free survival (PFS) and median overall survival (OS) of patients with HER2 overexpression gastric cancer treated with vidicon were 24.8%, 42.4%, 4.1 months and 7.9 months, respectively, which showed higher efficacy and better safety.
Therefore, China’s first original antibody-coupled (ADC) drug, vidiximab, developed by Rongchang Bio, went on the market, which filled the blank of back-line treatment for patients with gastric cancer whose HER2 was overexpressed in China.

As an ADC drug, vidiximab has the characteristics of antibody targeting and small molecule drug killing, and can accurately identify and kill tumor cells by targeting HER2 protein on the tumor surface. It has achieved world-leading clinical data in clinical trials for treating gastric cancer, urothelial cancer, breast cancer and other tumors.

Professor Shen Lin, vice president of Peking University Cancer Hospital, director of the Department of Gastroenterology and Oncology, and deputy director of Beijing Institute of Cancer Prevention and Treatment, said: "When vidiximab is featured by a wider range of treatment beneficiaries, a more balanced curative effect, safe benefits and a more economical and convenient detection process, and it has made revolutionary progress in the history of anti-HER2 treatment for gastric cancer, it is also inevitable that it will be highly recognized by National Medical Products Administration and the National Medical Insurance Bureau."

At the press conference on the adjustment of the national medical insurance drug list in 2021, Professor Shi Yuankai of the Cancer Hospital of China Academy of Medical Sciences mentioned that vidiximab is the first original antibody-coupled drug in China, and it has achieved good results in tumors such as gastric cancer and breast cancer. It is effective not only for patients with overexpression of human epidermal growth factor receptor -2(HER-2), but also for patients with low expression of HER-2. This time, the price of vidiximab was successfully reduced and entered the medical insurance, which benefited more cancer patients and filled the gap in the guarantee. While improving the drug guarantee for gastric cancer to the international mainstream drug use level, the burden on patients was greatly reduced.

Like Tatasip in the treatment of systemic lupus erythematosus, Videcituzumab is highly recognized internationally: this new drug is the first ADC drug in China that has been recognized as a breakthrough therapy by both FDA of the United States and NMPA of China. In August, 2021, Seattle Gene, an internationally renowned biopharmaceutical company, obtained the global (except Asia-Pacific) exclusive license agreement for vidicon with a down payment of up to US$ 2.6 billion and milestone payment, and a gradient sales commission of more than 15%. The transaction volume set a new record for overseas authorization of a single product of China pharmaceutical companies.

Innovative drugs are included in medical insurance, and the volume will obviously drive more innovations.

The medical reform in China continues to deepen, and the time for innovative drugs to be included in medical insurance has been greatly shortened.

The Blue Book on the Progress and Effectiveness of Medical Insurance Drug Management Reform shows that among the 34 innovative drugs listed from 2016 to 2020, 26 drugs have been included in the medical insurance catalogue, accounting for 76.5%. At the same time, in 2017, the time required for new drugs from listing to inclusion in medical insurance will be shortened to 1-8 years in 2019 and further reduced to 0.5-5 years in 2020.

The speed at which Rongchang Bio’s two innovative drugs entered the medical insurance is also a proper "top student". The characteristics of the two innovative drugs, such as "initiative", remarkable clinical effect, better safety and huge patient group, all escort their rapid inclusion in the medical insurance catalogue.

As for the new drugs with good curative effect, strong innovation and large clinical demand, it can quickly expand the sales channels and greatly increase the sales and market share of new drugs in a short time.

For example, according to the Blue Book on the Progress and Effectiveness of Medical Insurance Drug Management Reform, the dosage and amount of 17 kinds of anticancer drugs successfully negotiated in 2018 increased by 25.8 times and 8.8 times in the first quarter of 2021 compared with the first quarter before the negotiation (the third quarter of 2018); In the first quarter of 2021, compared with the first quarter before the negotiation (the fourth quarter of 2019), the amount of drugs successfully negotiated in 2019 increased by 10.4 times and the amount increased by 2.7 times.

Rongchang Bio-Tatasip and Vidicotuzumab are aimed at "a wide range of clinical unmet needs". With the opportunity of entering the medical insurance drug list, these two heavy new drugs may achieve rapid volume increase and gain more market share and economic benefits. And these will eventually lead to more innovations.

With the continuous introduction of policies to encourage innovation, such as accelerating the review of new drugs and normalizing medical insurance negotiations, enterprises that focus on early accumulation, do not blindly follow the trend of project establishment, and closely focus on how to solve the actual clinical needs are bound to stand out.

Rongchang biology is one of them.

Rongchang Bio, founded in 2008, has been focusing on the discovery, development and commercialization of antibody drugs such as antibody drug conjugate (ADC), antibody fusion protein, monoclonal antibody and bispecific antibody. At present, Rongchang Bio has developed more than 20 candidate biopharmaceutical products, and more than 20 indications of 7 products are undergoing clinical trials or have entered the commercialization stage.

In the best era of the development of innovative pharmaceutical companies, inclusion in the medical insurance catalogue has just begun for Rongchang creatures with outstanding research and development capabilities and rich reserves.

During the National Day holiday, there were frequent personnel movements, and visits to relatives and friends and trips abroad increased significantly. Warm tips from the National CDC:

Important tips

During the National Day holiday in 2024, it is necessary to focus on animal-borne infectious diseases such as infection, whooping cough, influenza, measles, dengue fever and human avian influenza, and norovirus gastroenteritis in novel coronavirus. When traveling abroad, it is necessary to focus on the epidemic risks of local infectious diseases such as dengue fever and monkeypox.

Before traveling, you should know the recent epidemic risk warning of the travel destination in advance and master the preventive measures; Outbound personnel need to pay attention to travel health tips issued by destination countries or regions.

During the trip, you should maintain good personal hygiene habits, pay attention to the hygiene of drinking water, wash your hands frequently, ventilate more, and prevent mosquito bites, take necessary protective articles and medicines, and do not share personal daily necessities such as toothbrushes and towels with others.

If you feel unwell after your trip, you should seek medical advice in time and take the initiative to inform your doctor about your travel history, so as to help with diagnosis and treatment.

Characteristics of related risks and specific preventive measures

Novel coronavirus infection

Novel coronavirus is mainly transmitted by respiratory droplets and close contact, but it can be transmitted by aerosol in a closed environment, and contact with articles contaminated by virus can also cause infection. The elderly and immunocompromised people are at higher risk of serious illness after infection.

Main preventive measures:

(1) Open the window regularly for ventilation to keep indoor air circulation.

(2) Try to avoid close contact with people with symptoms of respiratory infection and wear masks scientifically.

(3) The elderly, patients with chronic basic diseases and other severe high-risk groups actively take the initiative to vaccinate Covid-19 vaccine.

(4) When symptoms such as fever and cough appear, try to avoid participating in group activities, seek medical treatment in time, and wear a mask throughout the medical treatment.

whooping cough

Pertussis is mainly transmitted by respiratory droplets, such as coughing and sneezing of infected people, which spread bacteria into the air. Susceptible people are infected by inhaling droplets with bacteria. It can also spread through close contact. Parents or other residents infected with whooping cough are the main sources of infection for infants.

Main preventive measures:

(1) School-age children should be vaccinated as early as possible and throughout the whole process.

(2) Infants with persistent cough or shortness of breath, hypoxia, vomiting and other symptoms, especially when family members have cough symptoms, should seek medical advice in time.

(3) When family members have symptoms of respiratory infection such as persistent cough, they should see a doctor as soon as possible, and avoid close contact with infants under 1 year old. When caring for children over 1 year old in close contact, they should wear masks scientifically.

(4) Maintain good hygiene habits, wash your hands frequently and ventilate frequently, cover your mouth and nose with elbows or paper towels when coughing or sneezing, and pay attention to reasonable work and rest and proper physical exercise.

flu

Influenza virus is mainly transmitted by respiratory droplets, and can be transmitted by aerosol in a closed environment. Contact with items contaminated by virus can also cause infection.

Main preventive measures:

(1) Vaccination against influenza is the most economical and effective means to prevent influenza. Severe and high-risk groups such as the elderly and patients with chronic basic diseases should take the initiative to vaccinate against influenza.

(2) Promote frequent hand washing and avoid touching your mouth, eyes and nose with your hands. Cover your nose and mouth when sneezing and coughing.

(3) Try to avoid close contact with people with symptoms of respiratory infection. Open the window regularly for ventilation to keep indoor air circulation.

(4) When symptoms such as fever and cough appear, try to avoid participating in group activities, seek medical treatment in time, and wear a mask throughout the medical treatment.

measles

Measles is mainly transmitted by respiratory droplets, and can also be transmitted by direct contact with the secretions of infected people. Measles is one of the most infectious diseases.

Main preventive measures:

(1) School-age children should be vaccinated with measles vaccine in accordance with the national immunization program for children.

(2) Maintain good hygiene habits, regularly open windows for ventilation, maintain indoor air circulation, and try to avoid close contact with people with respiratory infection symptoms.

(3) When symptoms such as fever and rash appear, try to avoid participating in group activities, seek medical treatment in time, and wear a mask throughout the medical treatment.

dengue

Dengue fever is mainly transmitted by the bite of Aedes mosquitoes, which is mainly prevalent in tropical and subtropical regions. The epidemic situation of dengue fever in China is mainly caused by local transmission caused by overseas import.

Main preventive measures:

(1) Prevent mosquito bites. Wear long clothes and trousers when going outdoors, and spray mosquito repellent on exposed skin; Install mosquito screens indoors and hang mosquito nets when sleeping.

(2) Clear mosquito breeding ground in time. Indoor and outdoor water tanks, flower pots, cans and other water containers should be cleaned and changed in time, and the pots should be turned upside down to avoid mosquito breeding.

(3) Improve the awareness of self-treatment. Those who have lived in the place where dengue fever occurred within 14 days should seek medical advice in time if they have symptoms such as fever, rash, headache, joint pain and muscle pain, and take the initiative to inform them of their living history.

mpox

At present, both monkeypox virus type I and monkeypox virus type II are mainly transmitted by direct contact with the pathological secretions and exudates of patients. Common direct contact methods include sexual behavior, close contact at home, medical care contact and so on. Contact with virus-contaminated environment and articles can also cause infection, but the transmission efficiency is lower than that of direct contact.

Main preventive measures:

(1) Be the first person responsible for your own health, understand the knowledge of prevention and control of monkeypox, enhance self-protection awareness, reduce high-risk behaviors and reduce the risk of transmission.

(2) When going to an epidemic area of monkeypox, you should know the epidemic situation of monkeypox in the destination in advance, do personal protection, avoid contact with local wild animals, and avoid close contact with monkeypox patients or people with suspicious symptoms; Abide by the relevant national regulations on entry-exit management and cooperate with entry-exit quarantine inspection.

(3) If you have suspicious symptoms such as fever and rash and have a suspicious contact history recently, you should seek medical advice in time and inform the contact history. Self-health monitoring for 21 days from the onset of symptoms, during which close contact with others should be avoided.

Infectious diseases of animal origin

Contact with infected animals, livestock and poultry and their polluted environment, food and articles is an important way to spread animal-borne infectious diseases such as plague, human avian influenza, brucellosis, anthrax and rabies.

Main preventive measures:

(1) avoid contact with animals of unknown origin, do not hunt, strip, carry wild animals and their products, and do not eat dead animals.

(2) Do not directly contact wild birds and poultry, and do not buy live poultry from live poultry markets, live poultry stalls in farmers’ markets or mobile vendors.

(3) Do not slaughter or touch sick animals. When animals such as cattle and sheep suddenly die, don’t deal with them without permission, and immediately report to the local agricultural and animal husbandry department.

(4) After being scratched or bitten by dogs, cats and other animals, you should immediately wash the wound with soapy water, go to the hospital as soon as possible, and accept the preventive measures after exposure in a timely, standardized and whole process according to the doctor’s advice.

Norovirus gastroenteritis

Norovirus gastroenteritis is mainly transmitted through contact with infected patients and eating water and food contaminated by the virus.

Main preventive measures:

(1) Maintain good hygiene habits and wash your hands before and after meals, before processing food or after your hands are contaminated. Food should be steamed and cooked thoroughly, especially seafood and aquatic products. Fruits and vegetables should be cleaned. Do not eat raw or undercooked meat and seafood, and do not drink raw water.

(2) Articles and places contaminated by patients’ vomit or feces should be cleaned and sprayed with chlorine-containing disinfectants or other effective disinfectants in time, and contaminated clothes or sheets should be replaced and cleaned immediately. During disinfection and cleaning, you should wear masks and gloves, open the window for ventilation, and wash your hands thoroughly and regularly after treatment.

(3) Strengthen exercise, maintain a healthy and regular routine, and enhance the body’s resistance to viruses.

　　CCTV News:The State Council held a press conference on the 16th. Zhao Zhiguo, spokesperson of the Ministry of Industry and Information Technology and director of the Information and Communication Administration, said that the Ministry of Industry and Information Technology attached great importance to the protection of the rights and interests of APP users. In recent years, comprehensive measures have been taken to continuously improve the governance system. The related work has been promoted from four aspects, and new progress and results have been achieved.

　　First, we will continue to carry out rectification actions that APP infringes on users’ rights and interests. Organized the communications administrations of eight provinces (cities, districts) in Guangdong, Zhejiang, Jiangsu, Shanghai, Tianjin, Sichuan, Anhui and Inner Mongolia, carried out six batches of centralized sampling inspection, inspected 760,000 apps, notified 748 illegal apps, and removed 245 apps that refused to rectify, and continued to maintain a high-pressure shock to violations.

　　The second is to strengthen the supervision of key responsibility chains. Establish an application store ranking notification mechanism where the main responsibility is not implemented, and urge application stores to strengthen self-inspection and clean-up, remove the problematic apps, and carry out the review of new apps. By the end of May this year, the number of apps nationwide was 3.02 million, which was 13% lower than the 3.5 million apps before the Ministry launched special rectification. Through the adjustment of quantity and the removal of illegal apps, the quality of apps is optimized, so that compliant apps can develop healthily. At the same time, the discovery rate of APP sampling problems in the app store has steadily declined.

　　The third is to carry out special rectification of the problem of APP pop-up harassing users. Focus on two problems: it is difficult to close the information of open screen pop-up window that strongly reflects to users and using pop-up window to mislead users to click and jump to carry out special rectification. The masses’ reactions to these two problems are relatively concentrated. One is that they can’t be shut down, and the other is to mislead users to jump. According to statistics, in the second quarter, the number of complaints about APP pop-up information decreased by 50% from the previous month; Among the top 100 APP applications in terms of user usage, the discovery rate of the problem that it is difficult to close the screen information dropped from 69% to 1%. It turned out that the number of apps that found such problems was relatively large, but now it is getting less and less. The discovery rate of misleading users to click and jump by using pop-ups dropped from 90% to 12%.

　　The fourth is to vigorously improve the technical testing capability. Using big data, artificial intelligence and other technologies, we will continuously improve the automatic detection ability, monitoring ability and data analysis ability of the national APP technology detection platform. At present, the platform has the ability to detect 150,000 apps per month, and the detection coverage will reach 1.8 million apps before the end of the year.

　　In the next step, the Ministry of Industry and Information Technology regards APP governance as a concrete measure of "I do practical things for the masses", and strengthens its work from three aspects, with constant momentum and constant pace, and strives to create a safer, healthier and cleaner APP application environment for the broad masses of the people.

　　The first is to promote the improvement of management policies and industry standards. On the basis of fully absorbing the opinions from all walks of life, we will jointly issue and implement the Interim Provisions on the Protection and Management of Personal Information of Mobile Internet Applications with relevant departments. The previous paragraph of this Regulation was publicly solicited for opinions on the Internet, and all walks of life put forward some good opinions and suggestions, which we are studying and adopting. On this basis, it will be promulgated and implemented in conjunction with relevant departments as soon as possible. At the same time, it also organizes the formulation and improvement of relevant industry testing standards to provide more solid policies and standards for APP governance.

　　The second is to organize and carry out service perception improvement actions. Focus on some key links of users’ poor perception and experience of APP service, organize and carry out service perception improvement actions, and take effective measures to further promote the improvement of APP service quality. We plan to launch the "Service Perception Promotion Action" in the second half of the year, starting from the perspective of user service perception, to improve the governance strength and governance effect.

　　The third is to organize the issue of "looking back". On the basis of normal supervision, we will carry out a "look back" on key issues and key enterprises in a timely manner, and increase penalties for enterprises that repeatedly violate the rules to call the address book and the geographical location authority of users, so as to ensure that the rectified problems "do not rebound or repeat".

Editor’s Note: The new iPhone will be officially released tomorrow. The Verge has lifted the detailed evaluation of iPhone XS and iPhone XS Max. Let’s take a look at how the two most expensive iPhones in history perform.

The annual Science and Technology Spring Festival Evening passed, and the new iPhone arrived as scheduled in 2018. As a model with the name "S" updated, we didn’t expect the iPhone XS to change much in appearance, but the largest iPhone XS Max was the most concerned one in this new machine camp. So, as one of the most anticipated models in the world market this year, what is the specific performance of iPhone XS/XS Max?

In terms of appearance, in fact, we can completely ignore the iPhone XS. After all, it is almost exactly the same as the iPhone X, so let’s focus on the iPhone XS Max.

Apple’s first taste of the big screen dates back to the iPhone 6 Plus era a few years ago, and that generation of mobile phones also set a sales miracle in the history of the iPhone. After several generations of updates, it seems that Apple wants to do the same thing to the successor of iPhone X. Of course, it is reasonable for consumers to buy the big screen. After all, with the blessing of comprehensive screen design, the body size of iPhone XS Max with 6.5-inch screen is only 157.5*77.4*7.7mm, which is almost exactly the same as the Plus series with 5.5-inch screen (158.4*78.1*7.5mm).

Under such a screen size, watching videos or playing games with iPhone XS Max naturally has nothing to say. In addition, the OLED screen with wide color gamut display (P3), 625cd/m2 brightness and 458ppi makes the visual impact of iPhone XS Max higher than that of iPhone X by several gears. Of course, if you want to operate with one hand, it may be a little difficult. Even for users with large hands, it is almost impossible to hold the menu at the top of the operation with one hand.

As for the quality of this OLED screen, I think that after the self-certification of iPhone X in the past year, everyone has already had sufficient trust in it. At least in terms of screen burning, it has performed better than other OLED screen phones in the same period. However, there were many problems about the wear of iPhone X last year, and this year, Apple improved the material of the front and rear glass to make it more wear-resistant. According to foreign media inspectors, after streaking for more than a week, there were no obvious scratches before and after the mobile phone. As for the durability for a long time, it needs longer verification to get a conclusion.

In fact, from the current usage situation, Apple has hardly made too many software optimizations for this smartphone with a larger screen. No matter the application or UI, all we can see is just "bigger than bigger". In landscape mode, some native applications such as Safari have evolved, for example, the tab bar has become more accessible, which is largely due to the optimization of iOS12.

At the top of this screen, we still see the familiar "little bangs". As far as the unlocking efficiency of Face ID is concerned, iPhone XS Max has not changed much compared with iPhone X, and the improvement in unlocking speed in milliseconds is not obvious, and it still doesn’t recognize me who just woke up. Of course, the horizontal or upside-down unlocking previously guessed has not been realized in iPhone XS Max. Also affecting the unlocking are sunglasses that block infrared rays. It is said that Apple is cooperating with some sunglasses manufacturers to launch sunglasses that support Face ID in the future. It’s really "apple" not to adjust technology to solve the adaptation problem, but to ask others to cooperate with them to make changes.

The biggest change brought by Face ID is to expand the facial information to two people, that is, an iPhone XS Max can be unlocked by two pairs of faces entered in advance. Considering that Face ID adapts to the changes of users’ facial eyes, beards and other elements very quickly, there is no need to set a second set of facial information for backup. It seems that Apple just wants to provide users with an emergency unlocking solution, but it also gives your girlfriend more reasons and ways to unlock your mobile phone.

The lens quality of iPhone has always been obvious to all, and no matter which generation of iPhone, its shooting effect is among the top products in the same period. Although we often say that the iPhone is not as good as other products in targeted optimization, at least in terms of film quality, the iPhone is still worthy of pride. So how does it perform in iPhone XS Max?

At the press conference, Apple said that the shooting effect of iPhone XS/XS Max is still leading in the current smart phone market. iPhone XS Max still adopts the configuration of rear dual camera, but it has been upgraded for the previous 12-megapixel wide-angle lens with f/1.8 aperture, and the unit pixel area has been increased from 1.22um to 1.4um, which makes iPhone XS series phones more sensitive to light. Combined with A12′ s image information processing system and neural engine, a film with more ideal tolerance and color can be obtained by taking multiple photos and synthesizing them.

With the blessing of SmartHDR, the filming effect of iPhone XS series phones is really satisfactory. At least compared with the previous generation iPhone X, iPhone XS is obviously superior in exposure control, dynamic range and dark light performance. However, SmartHDR also makes the sharpness of photos lose, which leads to the improper handling of details.

This pot should be buckled in the so-called intelligent HDR. This function has done a lot of excesses in the details during actual shooting, which is why after enlarging the photo, you can clearly see the skin texture of the portrait chin and the texture of the eyebrows, which are all smeared out by the iPhone XS.

As can be seen in the photo below, the portraits taken by iPhone XS are as original as ever, while the photos taken by Pixel have better saturation. This is a contradiction between "truth" and "pleasing", especially for users who can’t take selfies and send friends without beauty. iPhone XS is undoubtedly "fatal" for them.

In portrait mode, iPhone XS has added a virtual aperture system. Through simulation algorithm, the blur effect of the background can be adjusted from f/1.4 to f/16 at will. All users need to do is turn on portrait mode, aim at the target theme and take the next photo. Because iPhone XS can distinguish and record the theme, foreground and background, the virtual depth of field effect can be adjusted in the later stage.

As for the blur effect, it can only be said that it is difficult for most smartphones to perfectly simulate the texture brought by the camera lens, and the iPhone XS is not much better in the end, but it is better than nothing.

In short, the camera performance of iPhone XS has made remarkable progress compared with last year’s iPhone X, but it can’t be said that it is easy to use. Its imaging effect can only be equal to several top Android flagships in the first half of this year. It’s not outstanding, but there are no obvious shortcomings. This is the consistent lens training style of iPhone.

In terms of processing chips, Apple has always been ahead of all its competitors. In this year’s A12, they also used the 7nm process first. Apple official said that this generation of chips has improved performance by 15% compared with last year’s A11, while GPU has improved by as much as 50%.

As for the performance improvement of 15%, it is actually difficult to experience it in daily use. After all, apart from the occasional system ventilation, the iPhone has not been associated with the word "Caton" for a long time. In short, whether it is a large game or a daily use, the iPhone XS is very smooth to use.

However, the more intuitive experience improvement brought by the 7nm process lies in the better power consumption performance. In the case of simple daily use such as sending emails, watching videos, taking photos, browsing social networking sites, etc., the iPhone XS Max can even be firm for 12 hours. As for the iPhone XS Max, the official claim is that the battery life is 30 minutes longer than that of the iPhone X, and this is because the battery capacity of the iPhone XS(2658mAh) is higher than that of the iPhone X(2716mAh).

We can see that the performance improvement of 15% is actually not obvious, which means that Apple has put more energy into controlling power consumption and heat generation. We should know that last year’s A11 has strong performance, but its performance in iPhone X is not ideal. To a large extent, it is a pot that triggers frequency reduction after high heat, and the A12 processing chip carried by iPhone XS can provide a stronger and lasting experience.

In short, A12 will be a chip full of more possibilities, and its excellent and stable performance will enable it to cope with various high-intensity applications in the coming year. For ordinary users, the battery life it brings can also improve the iPhone experience.

Whenever a new mobile phone is launched, people who eat melons will question whether it is worth buying. In fact, as a "make-up version" with the name "S", this is indeed a problem that needs to be considered. After all, the iPhone released this time is the most expensive iPhone in history, and the domestic version has even sold for more than 10,000 yuan, so it is reasonable to make some considerations.

Then if you already have an iPhone X, it is not necessary to upgrade to the iPhone XS at least. It is really easy to use, but the iPhone X is not a model that has been abandoned by the times. Even if it is put in the second half of this year, it is still the top flagship smartphone.

So how about buying an iPhone XS Max? If you want to experience a bigger screen, there is nothing to hesitate. After all, the experience brought by 6.5-inch and 5.5-inch is just like a world of difference. It can be said that iPhone XS Max is a mobile phone that will make people feel that there are no shortcomings. Everyone still needs to understand that even if it is the most expensive iPhone in history, it can afford such a price. After all, it is not its fault that it is expensive.

If you are holding an older model than iPhone X, then our suggestion is to change it if you can. It’s been 8102 years, and you haven’t got a full screen yet, so you are embarrassed to go out.

Cctv news(Reporter Sai Xinyan, Li Shanshan) "What you see is the special agricultural product of Zhangchangfeng Village: three red flags and four jars of sauce, no pesticides and no fertilizers. Flour is rich in micro-nutrients, and the taste is absolutely good. "The weight of a single peach is 0.5-0.8, and the sugar content is 15%-20%."

Zhang Weiting, deputy researcher of the Supervision Office of the State Bureau for Letters and Calls, and the "first secretary" of Zhang Changfeng Village, Haixing County, Cangzhou City, Hebei Province, impressed the introduction of agricultural products as well as the tour guide’s words.

Now Zhang Weiting is full of confidence, saying that "the name Changfeng represents the hope of the villagers, and I want to lead everyone to achieve a bumper harvest". In 2018, when I first came to Zhangchangfeng Village to help the poor, Zhang Yuting was not so chic. There are 438 households in the village and 125 poor households with established cards; The village is all saline-alkali land, and the yield of wheat per mu is low, so it depends on the weather to eat. But even so, Secretary Zhang led the villagers out of a "Changfeng" road.

"Tukela" becomes "golden pimple"

Zhang Weiting never helped the poor. Before coming to Zhang Changfeng village, she imagined that this small coastal village was a "paradise" facing the sea and blooming in spring. However, after coming here, I learned that the collective industry in the village is almost zero, and "the electricity bill can’t be paid soon." Without industry, the villagers can only go out to work and live a tight life. Once they are sick and hospitalized, they can’t get out 10,000 yuan or 20,000 yuan of life-saving money … …

In the eyes of the villagers, it is strange that Zhang Changfeng is not poor: "After hard work for half a year, an acre of wheat received 300 kilograms, and they all sold for more than 300 yuan. If you want to be rich, unless ‘ Tukela ’ Become ‘ Golden pimple ’ ！”

Zhang Weiting is trying to challenge this "impossible". The first thing she did when she came here was to transform the old primary school site that had been idle for many years at the entrance of the village into a village cultural and sports center. She believes that "finding a way to seek development in the village and letting the labor force return to work in the village" is the direction for the villagers to get rich, so that everyone should "form industrial ideas and believe that we can do business ourselves and have ambition".

However, where is the way?

On a visit to the villagers, Zhang Weiting took a bite of the steamed bread stuffed by the villagers. "Take a bite, it smells good! I found the taste of childhood in an instant. "When I asked, I knew that the dry land wheat" Dahongwang ",which is widely planted in the village, grew in saline-alkali land without pesticides, fertilizers and watering. Although the yield was low, it tasted good. Zhang Weiting seems to have discovered the "New World". She gave this steamed bread with "childhood flavor" to friends in Beijing to taste, and also found relevant laboratories to test it. Soon, experts came to the conclusion that "the growth cycle of hard wheat is long, and the content of potassium and plant protein is higher". Zhang Weiting was ecstatic, and the gluten of steamed bread is scientific.

"This is a good thing in a big city." After a family visit and a family talk, Zhang Weiting also found that there are still many "treasures" in the village: Chili sauce made by Dai Shufeng is loved by relatives and neighbors; The noodles pressed by Ma Yujuan are very strong without salt; Zhang Changfeng’s pasta is famous in the local area, and every family will make delicious noodles and steamed buns … … If you sell these to the city people, are you still worried that the villagers will not be rich?

Therefore, Zhang Weiting led the villagers to study and improve varieties in many places, and invited experts from Beijing to give lectures, leading the villagers to do deep processing, and produced special agricultural products such as stone mill wheat flour and rye flour. Unexpectedly, the villagers don’t think so. In the eyes of the villagers, these are just the most common things at home. They don’t cooperate with the establishment of a unified sales channel and don’t trust this new "temporary secretary".

In the end, Zhang Weiting had to take risks to acquire at a price higher than the market price, and then look for sales channels from her side: she recommended it to colleagues and classmates in the WeChat group; I bought it myself and sent it to a friend far away; Boarded the stage of "Open the Door" and Chongqing Satellite TV with "Zhang Changfeng" products.

　"Cultivate ambitious and wise villagers"

Zhang Weiting devoted herself to the work in the village. After the market was opened, Zhang Weiting found that the villagers had no uniform standard for the processing and quality control process of characteristic agricultural products. Once packed hundreds of boxes of carrots, the villagers’ packing quality was uneven. Most of them felt "indifferent", but Zhang Weiting felt that this was not a small problem. "You can’t smash your signboard because of small details." She and a few villagers re-examined and loaded hundreds of boxes of carrots, and told the villagers with actions, "Be wise and learn how to walk every step." Later, Zhang Weiting described that day as "really tired and falling apart".

"Don’t look at being a lesbian, you don’t want to work hard." Liu Yusheng, former deputy director of Haixing County Bureau of Commerce, said jokingly.

In order to make the rural characteristic products of Zhangchangfeng Village into brands, Zhang Weiting put forward the slogan that "China is good in Haixing, and Haixing is good in Changfeng", applied for registration of the trademark of "Zhangchangfeng", opened a shop on the platform of Wechat business, and set up a column of "Secretary Mall" in the village WeChat WeChat official account to plug in the wings of the Internet for characteristic agricultural products.

Open the "Secretary Mall" column of "Resident Poverty Alleviation Cadres" WeChat in WeChat official account, and the sales of pasta in Zhangchangfeng Village firmly occupy the top three, followed by the Chili sauce on "Open the Door". In recent months, Dai Shufeng, who makes Chili sauce, has sold hundreds of bottles of Chili sauce, earning nearly ten thousand yuan.

In addition, Zhang Weiting is also committed to the development of orchard construction. "Before, the information in the village was relatively blocked, and there was no investment and no labor, so there was no development. Now I am here!" In 2019, the total investment was 2.4 million, and the peach project covering an area of more than 100 mu was successfully "uphill". On September 21st, when Peaches entered the supermarket in Cangzhou, Zhang Weiting happily sent several friends in succession.

Zhang Weiting said: "It is my goal to push these things to the whole country. “

　"No, it feels like I’m going to be red."

The "first secretary" will not only develop industry, but also play well in Internet marketing. Zhang Weiting said with a smile, "It’s because many customers have given me advice. Recently, they suggested that I make a short video".

Zhang Weiting has a WeChat group to share the special products in the village. People inside value the unique quality of Zhangchangfeng village specialty and often contribute sales. "People say this is called community operation".

Zhang Yuting said that now 123 poor households in Zhangchangfeng Village have successfully lifted out of poverty, and the other two households have not lifted out of poverty due to mental retardation and other reasons. After consultation by the "two committees" of the village, the bottom-line policy will be implemented for these two special families.

Today, the flour in Zhangchangfeng Village is still the same flour, but its value has risen from 2 yuan to 12 yuan per kilogram. The income of more than 40 poor households doubled that year. Members of the cooperative work in the processing workshop, and they get 60 yuan’s salary every day, with dividends at the end of the year. "I didn’t expect the ‘ Tukela ’ Really became ‘ Golden pimple ’ ！” This seaside village is also quietly moving towards the carefree village of "spring blossoms" in Secretary Zhang’s heart.
