  Zhongxin. com, Chengdu, November 29th (Reporter Sun Zifa) — — The super-resolution lithography equipment project passed the acceptance test in Chengdu on the 29th. As one of the important achievements of the project, China scientists have successfully developed the world’s first ultra-resolution ultraviolet (i.e. 22nm @ 365nm) lithography equipment with the highest resolution, and formed a brand-new nano-optical lithography process route with completely independent intellectual property rights.

  Researcher Luo Xiangang, director of the Institute of Optoelectronics of the Chinese Academy of Sciences and chief scientist of the super-resolution lithography equipment project, said that in 2012, the institute undertook the development task of super-resolution lithography equipment, a major national scientific research equipment project. After nearly seven years of hard work, without foreign mature experience to learn from, the project team broke through key technologies such as high uniformity lighting, super-resolution lithography lens, nano-resolution focusing and gap measurement, and ultra-precision, multi-degree-of-freedom stage and control. The development of the first UV super-resolution lithography equipment with the highest resolution in the world is completed. It uses a light source with a wavelength of 365 nm, and the maximum line width resolution of a single exposure reaches 22 nm (about 1/17 exposure wavelength). On this basis, the project team also combined with the supporting processes such as high aspect ratio etching and multiple patterns developed by the super-resolution lithography equipment project to realize the processing of feature size patterns below 10 nanometers.

  The first ultra-violet super-resolution lithography equipment with the highest resolution in this world is developed based on surface plasmon super-diffraction, which breaks the traditional route pattern that the resolution of traditional optical lithography is limited by the wavelength of light source and the numerical aperture of lens, and forms a brand-new technical route from principle, equipment to process, with completely independent intellectual property rights, and provides manufacturing tools for the leap-forward development of revolutionary strategic fields such as metamaterials/hypersurfaces, third-generation optical devices and generalized chips.

  Acceptance experts believe that all technical indicators of the super-resolution lithography equipment successfully developed by Zhongke Optoelectronics meet or exceed the assessment indicators specified in the implementation plan, and the key technical indicators have reached the international leading level in the field of super-resolution imaging lithography. In principle, the project breaks through the diffraction limit of resolution, establishes a new research and development route of high-resolution and large-area nano-lithography equipment, bypasses the technical intellectual property barrier of foreign high-resolution lithography equipment, realizes the innovation of China’s technological source, and develops super-resolution lithography equipment with independent intellectual property rights and controllable technology, which is also the first ultra-violet super-resolution lithography equipment with the highest resolution in the world.

  At the same time, a series of nano-functional devices, including large-aperture thin film mirror, superconducting nanowire single photon detector, Cherenkov radiation device, biochemical sensor chip, super-surface imaging device, etc., have been prepared by using the successfully developed super-resolution lithography equipment, which verifies the processing ability of the nano-functional devices of the equipment and has reached the practical level.

  The super-resolution lithography equipment project of Zhongke Optoelectronics Institute has published 68 papers, and at present, it has been authorized 47 national invention patents and 4 international patents, and has trained a super-resolution lithography technology and equipment research and development team. Luo Xiangang said that the Institute of Optoelectronics of the Chinese Academy of Sciences will further increase the research and development, popularization and application of functional diversification of super-resolution lithography equipment to promote the development of related fields in the country.

15 new fashionable hairstyles, simple and beautiful, make you more addicted to cutting.

Women are fickle, as we can see from their hairstyles. Basically, every once in a while, they will go to the hair salon for a new hairstyle and find their own different beauty. Today, they have brought you 15 new fashionable hairstyles, which are simple and beautiful, making people more and more addicted.

Half-covered ears with short hair looming out of the ears are simple and fashionable, and bangs on the forehead retain a certain sense of quantity, which looks both age-reducing and textured.

Short hair can be said to be synonymous with ever-changing, especially the short hair with rich layers, which can present a very three-dimensional shape with hands and is fashionable and handsome.

If a woman’s hair is too short, it sometimes looks too neutral, but when it is long, it doesn’t look neat enough. Then you can try this kind of short hair with hanging ears, which is both soft and neat and suitable for most women.

Good-looking short hair can’t be separated from fashionable hair color. If you hang short hair, you can choose to match brown-red hair dyeing, which can not only increase the luster of hair, but also play a role in whitening the skin. The effect is beautiful and people like it more and more.

With creative hair dyeing, the effect is also very good, such as doing some bright highlights around bangs and ears, which will immediately give you a unique style and personality.

Soft hair cut one-size-fits-all bob, with neat bangs, is simple and pure but very stylish. Youth and fashion make people look smaller and smaller, and beauty is like 18 years old.

If you want to add a feminine style to the bobo head, you can consider trimming some layers at the end of the hair properly, so that it won’t look so monotonous, and the slightly buttoned shape is particularly thin-faced.

Coupled with a bangs about the length of Qi Mei, the trimmed layers should not be too thick, and keep a refreshing feeling, revealing the forehead faintly, naturally soft and particularly beautiful.

Of course, if you want to have a better fluffy effect, you can consider using a big barbell to perm your hair, so that the inner buckle effect of the hair end will be more obvious and the feminine temperament will be more in place.

Bobo hair style can also choose to dye the whole hair in dark brown, which is not exaggerated but very fashionable, with a small amount of highlights on one side. The three-dimensional fashion is very interesting and beautiful.

Hairstyles with bobo head length can be said to be suitable for ladies of different ages and younger ladies. When perming, the curl is too much, and the fluffy effect is OK, simple and fashionable.

Older ladies can curl up a little more, which makes them look more charming and can highlight the elegance of mature women, which makes people never tire of watching them.

If you have very little hair, you can also consider perming it with small curls, so that the fluffy shape can increase your hair several times, and at the same time, it is also foreign, which makes people like it more and more.

Curly hair styling is actually more suitable for female friends with shoulder length, because such a long curly hair makes people look particularly gentle and fashionable, especially when the curly hair hangs down, which can make the whole facial features get a good softening effect. At the same time, the outline of bitter fleabane bitter fleabane has the effect of face-lifting, which is simply addictive.

The permed hair forms even undulating waves, which looks a little retro, elegant and charming. I don’t know if it’s your favorite style. If you want to see more popular market hairstyles, don’t forget to pay attention to me.

I need you to be my friend, because you know how to listen to me and pay attention to me, thank you, and I hope you and I will go together in the future hair style.

Swimming tips can be learned in five minutes.

Many people want to lose weight by swimming. According to research, the energy consumed by exercising in water can be 20 times higher than that consumed by exercising on land, so more and more fat people have joined this sport. But there are many beginners who can’t swim. In fact, there are many swimming skills. After learning these skills, it is no longer difficult to learn how to swim.

Swimming skills

1. Breathe

Breathing in water is mainly divided into holding your breath and exhaling. If you master how to hold your breath and exhale properly, you will not be afraid of flooding. Inhale, lower your head, swing your arm when exhaling, then stroke your hand forward. When kicking, jump out of the water, inhale, and then lower your head. Cycle back and forth.

The pressure of water is obviously higher than that in air. It is definitely much more difficult to hold your breath and exhale in water than on land, so beginners should practice the basic essentials of holding your breath and exhale on land first, and then practice in water. Don’t inhale and spit it out immediately. You can try to get familiar with holding your breath.

2, rhythmic breathing

What is rhythmic breathing? In fact, it is the so-called regular and rhythmic breathing, without frequent or slow breathing.

Exhale through the mouth (nose) in the water, in addition to paying attention to the rhythm, you can cooperate with the action of pressing water with your hands. In the teaching of children, because there is often a problem of not standing at the bottom of the pool, the guidance of rhythmic breathing is more important, and coaches can regard breathing as the initial stage of ventilation. (Coordination action: 1. Keep your hands straight and merge, sink and exhale. 2. Press your hands to both sides to let your head rise and inhale.)

3. Balance

To make the center of gravity of the human body coincide with the floating center, we must first make people in a straight line, which is called the longitudinal axis of the human body. The head, shoulders, chest, waist, hips, legs and feet should be on the longitudinal axis of the human body, and when the arms are stretched forward, they should also be on the longitudinal axis of the human body; Secondly, press the chest to make the floating heart move backwards.

Pressing the chest is like an invisible hand pressing down on the back of the chest. In fact, it keeps the chest down to keep a certain pressure on the water. At the same time, the human body is a straight line, just like a seesaw, one end of the straight line-the chest is down, and the fulcrum is between the chest and abdomen, so the hips and legs at the other end will float up. Also, stretching your arms forward can move the center of gravity forward moderately. In this way, the body can be balanced and streamlined.

4. Relax

Relaxation in swimming is to minimize exertion under the premise of moderate tension or moderate exertion. So how to determine this degree? To find out this degree, you must first know how to exert yourself.

There are two kinds of human exertion, one is static. This kind of force will not change the shape; The other is motivation. This kind of force will cause the body to change. For example, weightlifters use power in the process of lifting barbells, while static force is used to keep the posture of lifting barbells; And the weight of the barbell is the degree of exertion. So this degree is the minimum force to maintain a certain body posture.

Playoff voice | Hot discussion Lakers win G3: Hamm points out the difference from playing. Magic number one Zhan Heqikua.

On April 23rd, Beijing time, after the total score of the Lakers was tied at 1-1, they returned to home in G3 and refused to be reversed by 29 points. They successfully beat the Grizzlies 111-101 to gain a 2-1 lead. After 1-1, the Lakers won G3 in nine consecutive series, surpassing Jordan Bulls to set a new record in NBA history. Lakers coach Hamm praised the players’ performance in this game, which was obviously different from the last game, and also praised the eight village bases for continuing to be brave.

After the game, Lakers coach Hamm was interviewed. He talked about the difference between G3 and G2, and the adjustment made by the team to win. Hamm bluntly said: "We just played more decisively, and the players were playing with goals and playing more disciplined. The other is our energy. The energy in the arena is bursting. Our concentration in this campaign is different from that in the last game, and our sense of urgency is completely different. "

As for the atmosphere of the Lakers playing the playoffs at home after ten years, Hamm said frankly: "Our fans are really great. They are unparalleled. We feel their enthusiasm and thank God. We give them something to cheer about, and we look forward to the next home game and feel the same way. "

Hamm also talked about the progress of Indiana Jones in the playoffs. He scored 20+ points in the first two consecutive games as a substitute, and scored 16 points in 6 out of 10 in this game. Ham praised: "When we got him, we were very excited. We are all encouraging him to continue to work hard, to be firm, confident and enterprising. You can see the love he gets. He himself once said that he fell in love with basketball again. "

Magic Johnson also praised the performance of the Lakers, "Lakers country! The Lakers played super antagonism on both ends of the offense and defense tonight! Our two superstars led the team to beat the Grizzlies 111-101. Brother Thick Eyebrows scored 31 points and 17 rebounds, and James scored 25 points and 9 rebounds. "

"I want to congratulate coach Hamm on his excellent adjustment at both ends of the offense and defense tonight."

As for the famous mouth Skip, it is also rare to praise the Lakers. "This is a great revenge victory for the Lakers. The only problem is that they let Morant find his rhythm and let him finally get 45 points. This is a moral failure for grizzly bears. If they persist, they will bring the momentum of the game to the evening of next Monday (US time). "

Decoding sustainable development: computing resources should be "alive"

[Global Network Technology Reporter Lin Di] At present, computing power has become one of the important supports for China’s high-quality development. With the advancement of the "East-to-West Computing" project and the explosive development of the artificial intelligence industry, the computing infrastructure construction represented by data centers has entered a new stage of high-quality and high-speed development.

Recently, the 17th annual ceremony of IDC industry in China focused on computing power layout, carbon neutrality, artificial intelligence, digital economy and other fields, and discussed the hot topics of data center industry such as high-quality development, new targets of carbon neutrality, hub node construction, and future computing scenarios.

He Baohong, director of the Institute of Cloud Computing and Big Data of China ICT Institute, analyzed the development trend of computing power. He pointed out that computing power is the core energy consumed in the digital world, and computing power is today’s "tertiary energy". In the past decade or so, the cloud, big data, blockchain and even the resources under the blockchain, as well as the big model of artificial intelligence, are pushing computing power towards concentration, and new ideas and solutions are needed to explore the sustainable development of computing power.

It is understood that with the accelerated integration of a new generation of information technology into thousands of industries, ubiquitous computing power is becoming a new engine to activate the potential of data elements and drive the digital transformation of the economy and society. Computing power has been widely used in digital government, industrial internet, smart medical care, distance education, financial technology, aerospace, cultural media and other fields. Among them, the computing power industry has continuously extended the industrial chain of Wulanchabu, such as server and cabinet manufacturing, data and network security, software research and development, data application services and other projects have been put into operation, boosting the construction of digital Wulanchabu.

Chai Yue, deputy mayor of Wulanchabu City, said in an interview that in 2022, the city’s computing-related industries completed an investment of 1.1 billion yuan, realized an output value of 2.6 billion yuan, and absorbed 2,700 jobs.

"The development of IDC industry can become a new kinetic energy for Wulanchabu to straighten corners and catch up later." Tong Xiaolin, the Big Data Administration of Wulanchabu City, pointed out that Wulanchabu has unique advantages in developing IDC industry. Wulanchabu is rich in energy, and the proportion of clean energy such as wind power and photovoltaic is high, and the natural cold source refrigeration time is nearly 10 months every year; Two point-to-point 144-core double-loop special optical cables with network delay less than 5 milliseconds have been built with Beijing. The geological structure is stable, the climate is cool, and the business environment is good.

Tong Xiaolin told reporters that the effective overall scheduling of computing resources, the matching of supply and demand, accurate configuration and the development of data center low-carbon life have become the primary issues facing IDC industry. "We have made several efforts-first, we have laid out energy-saving and energy-storage projects, and the" source, network and storage "integrated comprehensive application demonstration base project has been launched. The second is to encourage data center enterprises to adopt advanced green technologies such as high-efficiency refrigeration systems such as liquid cooling, distributed power supply, and modular computer rooms to reduce energy consumption. "

From the perspective of industrial demand, information technologies and applications such as 5G, industrial Internet, Internet of Things and artificial intelligence are accelerating their development and layout, and the demand for data centers is increasing due to the explosion of data volume. It is expected that in the next few years, the data center industry in Inner Mongolia will continue to maintain its growth trend by providing high-quality computing services for Beijing, Tianjin and Hebei.

Chai Yue said, "On the one hand, we attract data centers not only from the consideration of computing services, but also from the enterprise’s own innovative technology and comprehensive strength; On the other hand, we plan to build an integrated "cloudy" computing power dispatching center, which will guide the construction and access of computing power resources according to unified standards, realize the matching of computing power supply and demand, and improve the comprehensive shelf rate. "

In Zixing City, Hunan Province, the big data industry has promoted the development of industry and agriculture, and carried out scene applications such as smart city, industrial Internet, smart mine and smart agriculture.

Zhang Yong, deputy mayor of Zixing City, Hunan Province, told reporters that the "Dongjiang Lake Big Data Industrial Park" located in the scenic Dongjiang Bay is one of the most important explorations to develop the computing industry. In his view, the biggest demand for the development of IDC industry is the urgent need to introduce leading enterprises in IDC industry to form an industrial agglomeration effect. At the same time, it is necessary to introduce and cultivate data development and application enterprises and improve the upstream and downstream industrial chains of big data.

Zhang Yong pointed out that the next step will be to make computing resources come alive from four aspects. First, combine the action of "Giving Wisdom to All Enterprises" in Hunan Province, tap the value of industrial data, promote the deep integration of industrialization and informatization, promote intelligent manufacturing, and realize the digital transformation of industry; The second is to carry out the construction of smart agriculture, promote the application of Internet of Things technologies such as RFID, sensors and video surveillance in agriculture, and improve the level of agricultural digitalization; The third is to carry out construction actions such as smart transportation, smart medical care, smart education, and smart travel, promote the application of technologies such as big data, artificial intelligence, Internet of Things, and blockchain, and improve the digital level of social services; The fourth is to introduce and cultivate digital service enterprises, expand the ranks of enterprises, and improve the empowerment ability of local enterprises to apply the new generation of information technology.

Scientists hope to use artificial intelligence to find life on Mars.

It turns out that artificial intelligence may give us a better chance to find life on Mars.

A group of researchers led by the team of NASA Institute of Astrobiology (NAI) of SETI Institute recently released a study detailing how to use machine learning to more effectively determine where life may be hidden on the red planet, if it exists.

Scientists decided to use an area called Salar de Pajonales to run their project-this area is located at the intersection of Atacama desert and plateau, which is famous for being uninhabitable, but not uninhabitable-because it is considered as a good substitute for the surface of Mars. The team combined still images, samples and drone lenses to draw a map of life distribution in sparsely populated areas.

Then, the researchers brought the data back to the laboratory for training artificial intelligence. The goal is to teach computers to identify which areas are most likely to have life—such as small clusters of certain geological features or scarce water sources—and to be able to extrapolate this data to other locations. Theoretically, once AI knows the life-oriented details in Salar de Pajonales, it should be able to use these patterns to find the areas that are most likely to bear life in any terrain.

And the effect is surprisingly good. Once AI learns what it needs to recognize, researchers can combine machine learning with collected statistical ecological data to find signs of life 85% of the time. Without the help of artificial intelligence, the team was able to discover biometrics in less than 10% of the time.

You can imagine how helpful it is to find life on the surface of Mars. At present, we send rovers to the land of our next-door neighbors and look for life when they drive along their own paths. Although we try to choose a landing site that has a good chance of containing life (if it exists), it is different from the best and most promising area that the rover can microscopically observe around the planet it is driving.

The research team made it clear that although the speed at which artificial intelligence-assisted programs find life is incredible, it is equally exciting to find a process that can combine long-distance and short-distance data into useful maps to find microbial life. "Although the high biometric detection rate is the core result of this study, it is equally important that it successfully integrates data sets with different resolutions from orbit to ground, and finally links regional orbit data with microbial habitats," Nathalie A said. Cabrol, an astrobiologist and the lead researcher of NAI group of SETI Institute. "Our team showed a way to transition from the scale and resolution needed to characterize livability to the scale and resolution that can help us find life."

I hope we can integrate this technology into rovers, helicopters and drones going to Mars in the near future. Maybe this will be the ticket to finally find life on the red planet.

AI portrait, make your life more interesting!

In recent years, the technology with artificial intelligence as the core is innovating our life, work and interaction with the world around us. One of the latest innovations is the portrait generated by AI, usingDeep learning algorithmCreate realistic and artistic characters.

These AI-generated portraits not only make peopleFascinating and visually pleasing., but also has practical applications in various industries. For example, they can be used to create personalized avatars for social media profiles or as part of a virtual fashion and beauty try-on experience.

In addition, the portraits generated by AI may be changed through democratic artistic creation.art circles. With the help of AI, anyone can become a digital artist and create their own unique portrait with just a few clicks.

However, the rise of AI-generated portraits also raises ethical questions about privacy and consent. With the enrichment of personal data on the Internet, AI algorithm can easily create characters without people’s knowledge or consent, which may be used for malicious purposes.

Therefore, developers and users of AI-generated portraits need to abide by ethical standards and ensure respect for people’sright of privacy. This includes obtaining explicit consent before creating and sharing AI-generated portraits, and implementing measures to prevent the abuse of personal data.

In a word, the portrait generated by AI is an exciting development in the field of artificial intelligence and has many positive life-changing potentials. However, when approaching this technology, we need to handle it carefully and ensure that it is used responsibly while respecting people’sright of privacy.

ChatGPT is simpler than core-making? Zhou Hongyi: China can catch up with the United States in two or three years.

Because China’s science and technology started late, it is at a backward level in many scientific and technological fields, such as chips. However, western countries have already set up many technical barriers in the field of chips, so it is quite difficult to build a "Chinese core".

Of course, in addition to the chip field, the United States has also taken the lead in cutting-edge scientific and technological fields such as cloud computing, artificial intelligence and quantum computing, such as ChatGPT. With the global explosion of ChatGPT, technology companies all over the world are restless, and Google and Apple are scrambling to do it, and Chinese companies are no exception. So, in terms of ChatGPT, does China have a chance to catch up with the United States?

In response to this question, 360 Zhou Hongyi gave an unexpected answer. He believed that ChatGPT was easier than core-building. With the support of the state’s encouraging policies, China could catch up with the level of the United States in two or three years.

The reason why Zhou Hongyi can be so sure is because he knows enough about ChatGPT. As early as 202, when the first generation of ChatGPT came out, Zhou Hongyi had paid attention to it and conducted in-depth research. In his view, the success of ChatGPT has mainly done five things right, namely, open source, win-win cooperation, long-term persistence, ecology and user traffic.

First of all, when developing ChatGPT, OpenAI used a large number of open source algorithms and papers, and chose to cooperate with a large industrialized company like Microsoft, which saved itself a lot of trouble and solved the problems of computing power, data, business model, engineering and so on.

Secondly, from the very beginning, OpenAI was ready to fight a "protracted war", and like Apple, it worked hard to build an ecology and cultivated vertical applications based on ChatGPT. Thus attracting more users to use, and using user traffic can strengthen the learning and training of ChatGPT.

This is where China can learn. At present, if China wants to build its own ChatGPT, it can do it in terms of technology, strategy and language materials. Coupled with the advantages of open source technology and strong engineering and technology landing ability of China enterprises, it can already make ChatGPT-like products, so to some extent, making ChatGPT is easier than making cores.

However, after making a sample of ChatGPT, we need to spend more time on technological innovation, ecological construction and cooperation with Industry-University-Research, plus the support of the state’s encouraging policies. As Zhou Hongyi said, it will take two or three years for Chinese enterprises to catch up.

On the whole, ChatGPT is of great significance to the development of artificial intelligence in the future. Bill Gates describes ChatGPT as "as important as the Internet", Musk describes ChatGPT as "good and terrible", and Zhou Hongyi thinks that ChatGPT will bring a new round of information industry revolution. Technology bosses have high hopes for ChatGPT, and China version of ChatGPT can’t be left behind! Zhou Hongyi’s suggestion is worth pondering. What do you think? Welcome to comment!

Liverpool 0-1 Bournemouth relegation team Salah missed the point and the whole team was in a downturn.

"I have always hated losing," Salah said in a conversation with Gerrard this week. "I don’t like losing."

Liverpool supporters traveled long distances to the south coast of England, only to see the performance of their team once again. After klopp’s team was defeated by Bournemouth, they would undoubtedly agree with the Egyptians.

When substitute jota’s header hit Smith’s arm, Liverpool got an excellent opportunity to change the result of the game. The referee awarded Liverpool a penalty through VAR replay.

Milner, so reliable on the court, only played a few minutes ago, and his cross created this penalty opportunity. However, Salah is Liverpool’s first player. However, his shot was far from the right post of the goal, which greatly reduced the possibility of Liverpool becoming the top four for the first time this season.

Salah’s performance before he missed the penalty was hard to convince. He kept losing the ball, made the wrong choice and was easily intercepted.

Think less than a week ago, the 30-year-old player surpassed Robbie Fowler in the 7-0 victory over Manchester United to become the player who scored the most goals in Liverpool’s Premier League history, and he was happy to tear off his jersey. How high-spirited he was at that time.

However, Salah was not the only Liverpool player with a low performance. After 20 minutes of hopeful opening, the performance of the whole team was disappointing.

In five Premier League away games against Nottingham Forest, brentford, Brighton, Wolves and Bournemouth, Liverpool conceded 11 goals and scored only one. The recent setbacks are becoming the norm on Liverpool’s way forward.

The gloomy expression on Liverpool players’ faces on their way back to the dressing room after the game reflects their mood. I wonder if they can improve before the second leg of the Champions League against Real Madrid on Wednesday.
