Wi-Fi 6 has the characteristics of high speed, high density, low power consumption, and low latency. The industry generally holds optimistic expectations for its prospects. For example, Gartner believes that from 2019 to 2023, the Wi-Fi 6 enterprise and small and medium-sized business market will grow from US$250 million to US$5.22 billion, with an average annual compound growth rate of 114%.

The bright market prospects have attracted many powerful players, including Inspur.com. Zhu Lixin, general manager of Inspur Network Product Department, said that in combination with the trend of Internet of Everything, Inspur Networks has established itself as a market position of “closely combining Wi-Fi 6 with the Internet of Things”.

Wi-Fi 6 enters explosive growth stage

As a new-generation Wi-Fi standard, Wi-Fi 6 has greatly improved performance compared to Wi-Fi 5: capacity and speed are increased by more than 4 times; OFDMA (orthogonal frequency division multiple access) and TWT (target wake-up time) are introduced ) Technology, the former supports multi-rate, multi-device access, and the latter further reduces network power consumption and delay.

“Compared with Wi-Fi 5, Wi-Fi 6 has many improvements. It provides good support in terms of air interface utilization, high-density access, air interface security, and energy consumption.” Zhu Lixin believes that if 2019 is regarded as Wi-Fi In the first year of 6, Wi-Fi 6 has now entered an explosive growth stage. With the continuous popularization of terminals, more than 80% of Wi-Fi connections in the next two to three years will use Wi-Fi 6 technology.

Inspur Networks, which is optimistic about the development prospects of Wi-Fi 6, will begin to develop a layout in 2020. Of course, there are many established manufacturers in the Wi-Fi market, so how does Inspur Networks, as a rising star, establish its differentiated positioning? To this question, the answer given by Inspur Networks is “Internet of Things”.

From the perspective of market development trends, the Internet of Everything is moving towards the Internet of Everything and the Intelligent Connection of Everything, and the Internet of Things elements are getting stronger and stronger. From a technical point of view, Wi-Fi 6 adopts OFDMA technology, which can provide high bandwidth and multi-device access capabilities to meet The diversified access requirements of the Internet of Things, and TWT’s intelligent wake-up algorithm can fully reduce network power consumption and delay, and meet the low power consumption and low latency requirements of the Internet of Things. On the whole, the Internet of Things is the general trend, and Wi-Fi 6 naturally supports the Internet of Things.

Taking into account both Wi-Fi 6 and the Internet of Things, Inspur Networks has launched a solution that integrates the two: providing wireless access points with both Internet of Things and Wi-Fi 6 capabilities on the access side, and providing data communication services on the platform side The integrated Internet of Things is connected to the middle station to ensure that users can smoothly evolve from the Internet of Things access technology to Wi-Fi 6 in the future.

The Internet of Things is the core attribute

Zhu Lixin emphasized that the Internet of Things is the general trend, and future wireless networks must be native to the Internet of Things, and Inspur Networks solutions have good support for the native Internet of Things.

the first is safety , Implement the isolation of users, spaces, and applications through a containerized solution to ensure application security.The second is Openness , End-to-end support MQTT (Message Queue Transmission Protocol), which is different from the transparent transmission method, which prevents users from being “kidnapped” by a certain cloud service.The third is IoT perception , Through MQTT and CAPWAP (wireless AP control and configuration) to achieve dual-protocol plane business differentiation, to ensure a high perception of the Internet of things business.The fourth is Timeliness of IoT , The middle stage of the Internet of Things is linked with the back-end cloud platform to realize business deployment and linkage in a highly efficient and zero-code manner.

Among the above characteristics, the middle stage of the Internet of Things is particularly worth mentioning. “There are a large number of’chimney-style’ applications in the Internet of Things. The middle station of the Internet of Things connects applications and data at the connection point to achieve application integration and capability aggregation. The use of graphical drag and drop tools does not require programming to complete customer-defined intelligent application scenarios, making the Internet of Things From usable to easy to use.” Zhu Lixin said, “The Internet of Things has become the core competitiveness of Inspur Network Wi-Fi 6.”

Inspur’s Wi-Fi 6 solution has already shown its skills in the first trial. Zhu Lixin introduced that his solution has achieved key breakthroughs in education, medical care, manufacturing and other fields and has gained a place. It is also piloting Inspur’s own smart factory, setting a typical benchmark for Wi-Fi 6 empowering smart factories.

Looking forward to the future, Zhu Lixin said that Inspur Networks will launch more cost-effective converged access points and edge computing, and more powerful converged wireless controller products. At the same time, Inspur Networks will use the wireless and Internet of Things open architecture to join application ecosystem partners. Build a value plan together.

It is reported that Inspur Group is making every effort to consolidate and enhance its market position as an IT leader in recent years. Inspur Networks’ efforts in Wi-Fi 6 will surely enhance its wireless business capabilities, promote the realization of wired and wireless integration, and thereby improve Inspur Group’s network capabilities. , To provide help to strengthen the position of IT leader.

I knew you were “watching”

——AMTuring

In the autumn of 1950, Alan Turing, who was hailed as the “Father of Artificial Intelligence” by later generations, in the opening chapter of his book “Computing Machinery and Intelligence”, tossed out this seems to be “ Whimsical “The problem. Also in this article, Turing proposed a concept that appeared even earlier than “Artificial Intelligence (AI)”—— Turing test . This opened the prelude to human beings’ arduous exploration in the field of AI.

Time flies, and the stars change. Over the past 70 years, AI, which has experienced three waves of development, is quietly entering the daily lives of our ordinary people with various faces. Facial recognition, assisted driving, intelligent medical imaging and other applications are gradually becoming part of the “usual” part of human society, thanks to the continuous maturity of AI technology . And behind this is the continuous investment in AI research and development by academia, industry and even various countries. At present, the research and development of AI in countries around the world has gradually become a “race” trend. But to truly pass the “Turing Test”, no country has yet to be able to do so.

On June 1, at the 2021 Beijing Zhiyuan Conference, the ultra-large-scale intelligent model “Enlightenment 2.0” was officially released. With its 1.75 trillion parameters, it set the world’s largest pre-trained language model record and successfully demonstrated China’s AI technical strength to the world. It is reported that “Enlightenment 2.0” consists of four pre-training models of Wenyuan, Wenlan, Wenhui, and Wenshuo.

Among this, “Wenlan” is good at semantic understanding, visual-language retrieval, etc. Aroused great interest from Meike.com. It is reported that, Wenlan’s strong understanding of semantic information has reached the world’s “leading” level, which can be regarded as a breakthrough in the world’s AI field.Its capabilities are highly scalable and can be applied in a variety of scenarios . Through the research of Wenlan, human beings and the seemingly out of reach of the “Turing Test” are one step closer. The Wenlan R&D team is led by Professor Wen Jirong, Executive Dean of the Gaoling School of Artificial Intelligence at Renmin University of China, and works closely with Beijing Zhiyuan Artificial Intelligence Research Institute.

Picture | Professor Lu Zhiwu

Through hard work, we are honored to interview the head of the model group of the Wenlan R&D team—— Professor Lu Zhiwu from Gaoling School of Artificial Intelligence, Renmin University of China , And chatted with him about the future of AI and the story behind Wenlan.

AI development is gradually entering a bottleneck, and the multi-modal pre-training model led by Wenlan may become the key to “breaking the game”

As we all know, the ultimate goal of artificial intelligence is Let machines have the same understanding and thinking ability as humans . But more than 70 years have passed, and there is still a long way to go before this goal.

As far as the academic community is concerned, although many AI technologies can have a positive impact on human life, from the perspective of the general trend, AI research and development seems to be reaching a “ bottleneck “. Both the academic circle and the industry need to discover a new “hot spot” in technology to stimulate the entire AI industry to continue to develop by leaps and bounds.

In this case, “Wen Lan” was born.

Professor Lu Zhiwu told reporters, “ In the end, any AI model is actually a neural network. In the past, the industry often used pure text or pure image mode for unimodal training of AI.But now it seems that its effect is not particularly effective . ”

With academic development, The Wenlan team began to focus on pre-training using graphic data pairs at the same time, hoping to tap the new potential of AI . But before this, there has been no successful case in this direction.

In order to obtain better results, the training data used by Wenlan 1.0 and 2.0 Upgraded from 30 million to 650 million unlabeled graphic data. The huge amount of data is very difficult for model training, but it also lays the foundation for Wenlan to have strong visual-language retrieval capabilities and certain common sense understanding capabilities.

In terms of training methods, the Wenlan R&D team adopted an efficient distributed multi-modal pre-training framework and proposed a multi-modal pre-training algorithm based on DeepSpeed ​​to maximize the use of GPU and CPU and optimally support cross-modality Contrast learning.

At present, Google and OpenAI, the top foreign AI R&D institutions, are also trying the research direction of the Wenlan team. The project names are Google ALIGN and OpenAI CLIP respectively. Lan is obviously better, so to speak, At present, Wenlan has reached the top level in the world in terms of mutual inspection of pictures and texts and semantic understanding.

So, where can Wenlan be applied? Professor Lu Zhiwu told reporters that the current Wenlan, like a “brain”, is highly adaptable and can be used in multiple scenarios. Taking one of its strong “retrieval and recommendation” capabilities as an example, Wenlan can be “handy” in the common business scenarios of multiple sub-industries in e-commerce, games, and video.

Professor Lu Zhiwu said “ If the AI ​​we have learned in the past is only a child, now Wenlan is more and more likely to be close to an adult “.

Explore AI “subconsciousness”, “Turing Test” can see more dawn

Wenlan’s ability is beyond doubt. But for the Wenlan development team, After training on massive graphic data, does Wenlan really learn semantic information, and how strong is Wenlan’s understanding ability? , Has become a very attractive question.

For this reason, Wenlan’s R&D team decided to test Wenlan by means of “neuron visualization”. You can simply understand this as a “ Propositional painting “The test. We told Wenlan a meaningful sentence, let Wenlan feedback her understanding of this sentence in the form of a picture.

But please note that the picture feedback here is by no means matching the optimal solution from Wenlan’s existing picture data, nor is it an imitation of specific training data like some AI painting models.

At this time, Wenlan is more like an “ordinary person”. With the help of his own knowledge, he tries to understand the new information passed in from the outside world, and uses the form of pictures to “concrete” his own understanding. What the reaction is The objective existence in Wenlan’s “mind”.

Teacher Lu Zhiwu said “ (In this way) We visualize Wenlan’s “subconscious”, which is the most primitive imagination and understanding of a sentence in her mind . ”

How did Wenlan paint it? Simply put, we all know that on a computer, a picture is composed of pixels. By changing the color of each pixel, you can paint on the computer. And Wenlan, who got the text information, used this method to “original painting”, to express her understanding of the meaning of the sentences we gave with pictures. At this time, Wenlan can be compared to a balance. The two ends of the balance are images and texts. What Wenlan has to do is to make the meanings of the two “remain equal.” . It is worth noting that when visualizing neurons, all Wenlan model parameters are fixed and unchanged, only to modify the input initial noise image.

The Wenlan R&D team said: “ In this way, we can get a glimpse of Wenlan’s “inner world”. That is to let go of all evaluation and application restrictions on Wenlan, so that she can show the most primitive and true, unique understanding of the input text in her “subconscious”. ”

At present, according to Wenlan’s “paintings”, his ability to understand semantics has ranked among the top in the world. In addition to everyday language, Wenlan can also understand ancient poems and can even convey a certain “artistic conception”.

The following are some examples of Wenlan’s actual test (provided by Wenlan R&D team):

Statement to Wenlan: Make a wish on the birthday cake

(Interpretation: The image of the cake is very clear, there is also a candle, and there are dots and dots on the cake. The whole is a cheerful atmosphere for a birthday party.)

A sentence to Wenlan: The day is full of mountains, the Yellow River flows into the sea

(Interpretation: The mountain peaks in the distance obscured the setting sun but did not obscure the afterglow, and the nearby mountains ran towards us like a yellow river.)

Statement to Wenlan: The moon is falling and the sky is full of frost, Jiang Feng Yuhuo is sorrowful

(Interpretation: the red fire on the river, the awning boat nearby.)

Statement to Wenlan: You can pick lotus in the south of the Yangtze River, and He Tiantian with lotus leaves

(Interpretation: the budding lotus on the upper left, the lotus in the middle on the right, the lotus leaves and the whole green.)

Statement to Wenlan: The bright moon is born on the sea, and the end of the world is at this time

(Interpretation: The wavy sea below, and the rising moon on the sea. Although the original meaning of the verse is a full moon, it does not literally express the meaning of a full moon. The large abstraction of the background may be Wenlan’s interpretation of “the end of the world is at this time” Understanding.)

Foresight and persistence make Wenlan “come out of the sky”, diversification and intersection will become the new starting point of the AI ​​wave

For scientific research, correct judgment and persistence are sometimes more important than diligence and hard work. When talking about Wenlan’s research and development process, Professor Lu was deeply moved by it.

Since September last year, the Wenlan team has been working on multi-modal pre-training. Thinking of the process at that time, Professor Lu described: “ It was completely groping in the dark, and the multi-modal pre-training model was very difficult to do, but I still walked down this road decisively (weak correlation between graphics and text + two-tower model). ”

But exploration and persistence are risky. During this period, Professor Lu and his PhD students devoted themselves to this project, and therefore did not publish a paper for a long time. If the direction is wrong, or the model is not trained well, it will be a “grainless” result. The pressure on the entire team can be imagined.

At almost the same time, the front runners in the foreign AI industry: Google and OpenAI, are also doing similar things. And in January of this year, OpenAI released two models similar in direction to Wenlan: DALL-E and CLIP. While shocking the industry, it also proved that the selection of Professor Lu’s team was correct and forward-looking.

However, from the perspective of academic research in domestic universities, universities such as Qingbei seem to have more advantages in AI. Why is the National People’s Congress making a breakthrough in the AI ​​field this time?

Professor Lu Zhiwu believes that the advantage of the National People’s Congress lies in its liberal academic atmosphere and rich cultural ideas.

“ Dean Wen Jirong of Hillhouse College of Artificial Intelligence is very supportive of these valuable explorations.So our overall academic atmosphere is still very relaxed and open . ”

In addition, as a higher education institution specializing in humanities and social sciences, the National People’s Congress has its own unique way of understanding AI. In a sense, in view of the prevailing instrumental rationality, the National People’s Congress tends to be more value rational. This is also one of the reasons why Wenlan’s team was able to take the risk of “no revenue for particles” and insist on completing the research.

In the view of Meike.com, In addition to the unique advantages of the National People’s Congress, Wenlan’s success is inseparable from the forward-looking AI development possessed by Professor Lu Zhiwu, and the excellent capabilities of the entire Wenlan R&D team. .

On the long journey of AI exploration, “breaking” and “standing” are eternal topics. Although Wenlan has made breakthrough achievements, Professor Lu Zhiwu still modestly said that, on the whole, the future development of AI still requires the joint progress of related interdisciplinary subjects such as brain science and neuroscience. However, if the road is hindered and long, the line will come. we believe, Driven by the successful case of Wenlan, more “Wenlan” can emerge in China in the future, so that it can take off the “Turing Test”, the crown of AI, in one step faster. .

Conquer the universe. Photo: Space News. The Korean Ministry of Science, Information Technology and Communication hopes that by becoming the 10th member country of the Agreement, Seoul will further expand cooperation in the field of space with Washington, participating in various fields. the Artemis space exploration program. Accordingly, about 10 years later, Korea will have development steps in space technology on par with the previous potential country. The impetus for Korea to accelerate in the space race Compared to the space powers, Korea has a late start, but the development has positive and rapid results. After the launch of Naro rocket weighing 140 tons and failed in 2013, in 2016 South Korea carried out a Project to develop a spacecraft to explore the Moon worth more than 197.8 billion won (more than 166 million USD). ). As planned, this probe will be equipped with a series of cameras, sensors and spectrometers to collect data on the Moon as well as conduct space connectivity tests. At the beginning of this year, South Korea decided to invest 615 billion won (about 549 million USD) in space projects this year, including plans to launch the first rocket built and developed by the country. new satellites. Accordingly, South Korea also plans to launch a new 200-ton Nuri rocket later this year while a second launch, carrying a satellite, is scheduled for May 2022. In addition, the country will invest 322.6 billion won in projects to develop technology and services for new satellites, and plan to launch a new generation of medium-sized observation satellites next March in Kazakhstan. and is developing a new geostationary communication satellite to put into Earth orbit. Along with participating in the common playing field, Korea’s first lunar orbiter (KPLO – Korea Pathfinder Lunar Orbiter) scheduled to launch in August 2022 has also been developed in cooperation with NASA. In addition, ShadowCam, a device that can overcome visibility limitations to record images in dark areas on the Moon will be installed on this orbiter. ShadowCam is expected to return to the moon’s unlit areas to find potential landing points for the Artemis program. With this event, Korea has gradually developed domestic space technology, combined with the cooperation of other space powers in the world, will gradually occupy an important position in the field of space development. Generally speaking. With this participation, South Korea looks forward to setting a goal of sending its own spacecraft to the Moon by 2030. Accordingly, the country actively promotes challenging space exploration projects, by develop its own launch vehicle and by 2030 can achieve its dream of landing on the Moon. This first step will provide a solid foundation for Korea to conquer space. Korea wants to strengthen national security through this race? Over the centuries, we have witnessed many wars on land and at sea, and those wars have proved the strength of the victors and as well as the lesson of ensuring the safety of the nation, nation. And recently, we have heard and seen the so-called “ocean wars”, meaning the wars in the sea have also begun. As for outer space, decades ago, great powers in this field such as Russia and the United States developed it. And this same nation has also had competition in the conquest of space. The fact that Washington is conducting a manned lunar exploration program, a program to send astronauts to the Moon 50 years after the Apollo project in the 1970s is a sign that the US clearly has a great advantage in this field. race presence on Mars. However, experts say, so far, no country has been confident that it can send people to this planet located 225 million km from Earth. In the context of the race that has shown signs of heating in recent years, and with many worries that the Earth is becoming more and more crowded with humans, Russia and the US are both showing their ambition to soon bring humans to live. on the Red Planet and marks its sovereignty over space entities, including the Moon. From that perspective, the US wants to take action so that space activities can be transparent, preventing disputes over space activities. South Korea cannot stay out of this competition as an ally of the United States. South Korea has begun a feasibility study for a mission to discover the near-Earth asteroid – Apophis. This ensures competitiveness, but is also a first step to position the country on another planet with life in the future.

27P53 hybrid rice model in Thanh Chuong, Nghe An. Pioneer (now Corteva Agriscience) has pioneered in investment, research and development of new generation 3-line hybrid rice varieties. By applying scientific and technological advances, especially molecular biotechnology, successfully hybridized and commercialized the rice variety PHB71, which is one of the first high-quality hybrid rice varieties that retains high yield. planted in Vietnam in 2010. The year 2019 marks a new turning point in the research, introduction, selection and development of 3-line hybrid rice, when Corteva Agriscience launched the 27P53 rice variety. This is a new generation 3-line hybrid rice that has been evaluated by the Scientific Council for Seed Recognition of the Ministry of Agriculture and Rural Development as a rice variety with outstanding yield and quality, wide adaptability, good resistance to pests and diseases and adverse external conditions. The variety was officially recognized by the Ministry of Agriculture and Rural Development in October 2019. The 27P53 variety has a short TGST, only from 120-125 days in the spring crop, 100-105 days in the summer-autumn crop and the Mekong Delta. After the 27P53 rice variety was officially recognized, farmers in the rice growing areas received and planted it on a large scale throughout the provinces of Nghe An, Thanh Hoa, Yen Bai, Cao Bang, Dak Lak… bringing high economic efficiency. . Farmer Luu Xuan Bay, Phu Thanh commune, Yen Thanh, Nghe An, shared: “Through the practice of 3 production seasons, the 27P53 rice variety is easy to sow, the seeds germinate well, the seedling has good cold tolerance, and the tillering is healthy. and concentrated, less ineffective, resistant to pests and diseases. Especially, rice variety 27P53 has outstanding resistance to falling, high yield from 8-9 tons/ha, high quality rice and rice. The rice grain is long, less white, clear, and the rice is soft, and when cooled, the rice still retains its original softness, this is the best hybrid rice variety that I have ever grown. Model of a large sample field (65.67 ha) spring 2021 crop in Yen Thanh, Nghe An. According to Mr. Nguyen Tien Duc, Director of Nghe An Plantation and Plant Protection Sub-Department: “Nghe An is a large hybrid rice growing province with more than 40,000 ha/year. The presence of good varieties such as 27P53 is of great significance to the locality because some varieties have not kept their original stability.” Present in Vietnam since 1995, Corteva Agriscience always strives not only to provide innovative and sustainable solutions but also to improve the quality of life of the community. The introduction of 3-line hybrid rice varieties such as 27P31, 27P53 into production contributes to helping farmers increase productivity, quality and economic efficiency from rice cultivation. “With more than 200 years of expertise and experience in the field of agriculture, as well as for the past 25 years with Vietnam Agriculture, Corteva Agriscience is committed to continuing to accompany Vietnamese farmers”, Mr. Ngo Lanh, Sales Director Corteva Agriscience Vietnam shared. Corteva Agrisciences is a merger of 3 companies Dow AgroSciences, DuPont Crop Protection & DuPont Pioneer with the goal of becoming an independent agricultural company leading in seed technology, pesticides and digital agriculture, helping to maximize optimize farmers’ productivity as well as build a sustainable agriculture globally. DuPont Crop Protection was founded in 1802, Dow AgroSciences was founded in 1897 and Pioneer was founded in 1926. Over the past 200 years, the three companies have provided groundbreaking, sustainable solutions in control. insects, weeds, pests and diseases, and pioneering the research and development of hybrid rice and maize hybrids that help farmers improve yields and crop quality worldwide. 2018 marked a turning point in the history of the global agricultural industry when 3 companies completed the merger to officially operate under the name Corteva Agriscience.

Part of this 58-year-old male patient’s vision has been restored, allowing him to recognize, count, locate and touch various objects displayed on the table in front of him. (Photo: New York Times) According to research results published on May 24, scientists in Europe and the US have applied optical genetic engineering to treat a patient who lost vision due to an inherited disease of photoreceptors. 40 years ago. This involves injecting them directly into the patient’s eye, combined with stimulation for several months by wearing light-emitting glasses, which convert images into pulses of light printed onto the retina. A 58-year-old blind man was able to partially restore vision in one eye with the help of a breakthrough treatment using genetic engineering and light-activated therapy. The patient, who lives in France, was diagnosed with retinitis pigmentosa (RP), a degenerative eye disease that affects the retina at the back of the eye and causes it to stop working, almost 40 years ago. year. However, several months after the treatment, he was able to recognize, count, locate and touch various objects with the treated eye while wearing a pair of light-stimulating glasses. The researchers say that although their findings, published in the journal Nature Medicine, are still in the early stages, their work could be seen as a stepping stone to targeted treatments. new target for people with RP (RP – a condition in which the cells in the retina that receive light are disrupted, which can lead to total blindness). It is the most common inherited eye condition, affecting around 1 in 4,000 people in the UK. The researchers used a technique, called photogenetics, to genetically alter cells in the retina so that they produce light-sensitive proteins called channelrhodopsin. The treatment, which is done by injecting an eye into one eye, activates the gene that codes for a channelrhodopsin protein called ChrimsonR, which senses amber light. The team also developed specialized goggles equipped with a camera to capture and project visual images onto the retina at amber wavelengths of light. The patient then trained for several months as the genetically engineered cells began to stabilize. Seven months later, the patient began to show signs of improvement in vision, the researchers said. The team also said their patients were “excited” after this first experience of partial vision. With the aid of the light-stimulating glasses, the patient was able to locate, recognize, touch and count objects such as notebooks, pin boxes and glasses on a white table in front of him. The researchers also read the patients’ brain activity using a technique known as an electroencephalogram. A tortoise is alternately raised or removed from the table, and the patient must press a button to indicate whether it is there or not. The results from the experiments show that patients can recognize with 78% accuracy. Although this type of optical genetic therapy may be beneficial in restoring visual function in people with RP-related blindness, more results from this trial are needed, the researchers say. clearer picture of the safety and effectiveness of this approach. José-Alain Sahel, lead author of the study from France’s Sorbonne University and the National Center for Scientific Research, said: “It is important that blind patients suffer from various types of neurodegenerative diseases. and functional optic nerve would likely qualify for treatment. However, the effectiveness of the treatment depends on the extent of the patient’s optic nerve degeneration. He said it will take more time to study this method before it can be put into practice.

In the memory of many Hanoians, bougainvillea is associated with old houses or perennial dormitories. In the summer, especially from May, bougainvillea blooms on the streets and alleys. In Hanoi, it is not difficult to see confetti. As a result, the surrounding scenery also becomes softer and more romantic. The bougainvillea is native to Central South America. The plant is suitable for tropical climates and flowers all year round. In Hanoi, paper flowers are planted everywhere such as parks, schools, hospitals, medians, sidewalks. There are also times when bougainvillea is grown in a pot and posed as an ornamental plant. But the most special is the image of confetti embracing each small house. Paper flowers adorn the door frames more poetic, people feel light, peaceful and serene. The bougainvillea flowers almost bloom throughout the four seasons, but it seems that in May, this flower has a more radiant beauty in each sunny patch. Paper flowers always appear as a highlight, although gentle but impressive enough to attract all attention. The bougainvillea flowers are fast growing, easy to grow and care for, the flowers are wrong and have a variety of colors, symbolizing a love that is sincere, rustic, simple, simple. Tiny confetti, fragile petals but blooming in large bunches, are also representative of family affection. Each fragile flower is attached to each other to survive, against strong winds and heavy rain, like the love of brothers in one family. The pink color of confetti is like a special “dot” feature of collective houses in Ha Thanh. Paper flowers have many colors, in addition to the main pink color that we often see, confetti also adorns themselves with pure, gentle white flower clusters, making many people unable to take their eyes off when passing by.

The wedding dress was inspired by the dress Audrey Hepburn wore in Funny Face. In the film, Hepburn wears a minimalist dress with a high neckline, low waist, and fluttering skirt, wearing a chiffon scarf accented with a bow on her head.

On each microprocessor there are billions of transistors and nm (nanometer) – the unit of measurement of transistor size. The smaller the size, the more transistors the processor can hold, making it faster and more efficient. TSMC’s most advanced chip today uses a 5 nm process with about 173 million transistors per square millimeter. Silicon chip wafers in TSMC’s production line. Photo: TSMC. This breakthrough was discovered by the MIT team, with components optimized by TSMC and improved by NTU. The core component uses semi-metallic bismuth as the electrode of a two-dimensional material to replace silicon, allowing for reduced resistance and increased amperage. Energy efficiency will thus rise to unprecedented heights in the semiconductor industry. Chipmakers have been trying to stuff more and more transistors into increasingly smaller chips, but are nearing the limits of silicon-based technology. That prompted scientists to look for two-dimensional materials to replace silicon to produce chips on the 1 nm process or smaller. More transistors on a chip gives manufacturers more options to deliver core innovations to improve performance for leading tasks like AI and cloud computing, and pave the way for better security. Encryption and encryption are performed by hardware. The need to increase performance and save energy in each processor has never cooled down, especially in the era of the cloud, AI, and IoT. Most of today’s chip-integrated devices use 10 nm or 7 nm process technology. The two largest chip manufacturers in the world, TSMC and Samsung, are launching chips with the 5 nm process, while Intel is still at the 7 nm stage. TSMC also only plans to start moving to the 4mm process later this year before mass production in 2022.

4DFWD is a shoe version that uses the latest advancement of adidas 4D technology. In the lab, more than 5 million meshes were studied to find the most perfect bow geometry for the FWDCELL knit mesh soleplate made of 40% biomaterial, specially encoded for compression. forward when there is vertical force. Compared to previous 4D midsole generations, the adidas 4DFWD produces three times the optimal forward movement. As a result, the peak of braking force when the athlete is stalled during the run is reduced by 15% because the midsole has redirected the longitudinal forces into a translational movement in the horizontal direction – providing the same running performance with Ultraboost series midsole under laboratory conditions. In addition, adding an additional advantage to the 4DFWD midsole is the new Primeknit upper (upper) made from recycled polyester, giving runners the full experience of a premium sole. Ultra light and compact feet. Posts: Nice News

The music scene revolves around the phrase “Gucci” like “ Gucci Gang “,” Green Gucci Suit “, Gucci Flip Flops “… Being used at the BST launch show shows that Gucci is not only an influential brand in the billion-dollar fashion industry, but also contributes a significant part to trendy Pop culture.

I also uplifted the sensuous beauty of the once Marilyn Monroe icon and the enchanting glamor of an ancient Hollywood capital. And I also broke the shyness and discreetness of the bourgeois style as well as the men’s custom of tailoring to become softer and more defiant. “Gucci’s Creative Director confided. The colleague who helps Alessandro Michele take the creations of this 100th anniversary collection to new heights is none other than close friend Demna Gvasalia, Balenciaga’s Creative Director. For Michele, he did not call this a handshake or a special capsule collection, but rather an opportunity to “penetrate and transform” Demna Gvasalia’s un-stereotypical creations. His ambition is expressed through fashion items that cleverly combine the iconic designs of Balenciaga under Demna Gvasalia with the iconic designs of Gucci. For example, Balenciaga’s bell-shaped suits follow Gucci’s brown-black palette, Balenciaga’s renowned Knife boots have changed their look impressively on the GG Supreme and Gucci Flora motifs. bearing the hallmarks of the 60s, or Balenciaga’s Hourglass bag, which is hunted by women, now appears with the unique GG logo version … promising to “sell out” as soon as the sale starts.

Yingda Securities chief economist Li Daxiao said that the three major US stock indexes fell sharply by nearly 1% overnight, affecting global stock market sentiment. As of 10:23, net purchases of northbound funds reached 2.172 billion, and the Shanghai Composite Index rose 11 points, an increase of 0.33. %, this is extraordinary. The A-share market has shown rare mavericks. my country’s economy grew by 18.3% in the first quarter, a record high. In the first quarter, GDP reached 25 trillion yuan. In the first quarter, the output value of industrial enterprises above designated size increased by 24.5% year-on-year, and the total retail sales of consumer goods increased by 33.9%. The epidemic situation in our country is well controlled, which is an important guarantee for economic growth. Chinese people are willing to travel on May 1st, and consumption will explode soon.

The semi-annual report forecast time has come again, and the performance factor is becoming more and more important. The performance growth factors of listed companies play a positive role in the market. Foreign investment variables are often a catalyst for A shares, and the long-term financial stabilization effect of domestic investment will play an increasing role. This is the basic market.

A larger increase comes from household savings, which is the long-term source of funds for China’s stock market. China’s stock market has been consolidating longer and longer, and the probability of changing the market has become greater and greater. The stock market proverb says that it should not fall, and the market outlook is bullish. Whenever the United States has fallen sharply in recent times, A-shares stand proudly, and perhaps a breakthrough is imminent. Of course only good stocks.

I think the probability of upward breakthrough is higher, of course it is just what I think. It is lonely and stressful to make this point, and it may be wrong, but that’s what I think.

Reporter | Wu Yangyu Reporter | Wu Yangyu On April 21, Keep held the 2021 strategy and new product launch conference. In addition to upgrading the Keep App to version 7.0, it also launched important updates on its content and hardware product business lines, including three premium IP courses and Keep Intelligence. Two smart hardware products, the spinning bike C1 Pro and the Keep bracelet B2 member special edition. Keep, launched in 2015, has grown into an App with 300 million users and 6 million daily activities. In terms of the country’s nearly 700 million people with sports needs, Keep believes that there is still room for growth. In six years, its growth path is also very clear. In the three years after 2015, it relied on tool attributes to achieve a scale of 100 million users. With the further exploration of user needs and the inevitable monetization attempts, starting in 2018, it began to build its own sports consumer brand from scenes such as eating, wearing, training, etc., while continuing to promote online businesses with higher profit margins such as membership and advertising.化 means. Today, after three years of commercial testing, Keep is about to enter the next stage. Earlier, some media reported that Keep planned to go to the United States for an IPO in the second quarter of this year (or July), and submit a prospectus to the U.S. Securities and Exchange Commission (SEC) as early as the end of April. According to Sina Finance, Keep recently appointed a new CFO, established an investor relations department, and recruited an investor relations director. In this regard, the Keep official has not yet responded. If the news is true, this strategic announcement may be the last important adjustment of Keep before becoming a listed company. Can it win the support of users and the trust of investors?

What is an open sports platform?

From the perspective of Keep, the company has reached the third stage of its development.

The positioning of the first stage is the most well-known, a mobile fitness app for users, emphasizing the attributes of tools; the second stage is the commercial landing of eating and wearing exercises around the family scene, with the goal of becoming a new generation of sports brand.

After tools and brands, Keep aimed at the “open sports platform” at this stage. Peng Wei, co-founder of Keep, said that the focus of this stage is to provide users with more value-added services.

In fact, if you look back in the past, you will find that Keep is still continuing the business pattern that has been formed before.

In June last year, Keep partner and vice president Liu Dong told Jiemian News that Keep’s commercialization pattern is divided into three quadrants: A, B, and C: A and C are the existing foundations, which respectively refer to the user scale (currently 300 million) And the sales scale of sports consumer goods (existing 1 billion GMV), on top of which is the value-added business B that provides users with sports solutions, including but not limited to members and live lessons.

Therefore, what Keep does can be attributed to three directions: user scale, sales scale, and consumer products or App functions that may generate value-added services.

Back to the present, content and hardware products will become the two most important tentacles of Keep in the third stage. Hardware products stimulate sales, content supports value-added services, and the two share the task of user retention.

On the content road, Keep has crossed the threshold of winning by quantity and made it clear that it will pay more attention to quality. However, high-quality content is also a high consumption of team capabilities. In order to ensure that output efficiency is not affected, Keep’s idea is to increase investment in self-developed IP while building an open platform and introducing PUGC and brand institutions as another content source.

It is understood that there are currently more than 1,200 self-developed PGC courses on the platform. The three courses of temperament ballet, hot sweat yoga, and fat burning party launched at the press conference are the further development of Keep on self-developed IP. explore. In addition to recorded classes, Keep’s current live classes have also covered 8 am to 10 pm.

As for “opening up”, Keep said that 3,000 athletes have settled on the platform, including Pamela, Xiao Ma, and Saturday Ye, who are on fire on content platforms such as Station B and Xiaohongshu. At the same time, overseas content IPs such as Zumba and Laimei have also been introduced.

Keep’s determination is obvious. Prior to this, user feedback about the various messy entrances of the Keep App interface was by no means a few, and the updated App 7.0 version absolutely reserved the home page for “content”, and the “mall” including sports consumer goods was brought to the end. unit.

“Users can better find courses that meet their own needs on the homepage, and the efficiency of searching has become higher.” Peng Wei said. From “I want to show users everything” to the refreshing interface with content-oriented, the goal that Keep wants to achieve the most now is very clear.

For another link hardware product, Keep made it clear that technology will be the next trend in hardware products.

Take this smart spinning bike C1 Pro as an example. It broke the price range of Keep’s control of related categories at around 2,000 yuan and reached 4,999 yuan. The main reason was the addition of a 21.5-inch screen and a number of smarter ones. Interactive features.

The highlight of the screen is the ability to switch between the bicycle interface and the App interface system by flipping. Users can also participate in other recorded and broadcast classes and exercises while using the bicycle.

In addition, 80% of Keep’s spinning users will practice with live classes. In the past, when the coach reminded to increase the resistance, the user was required to twist it manually, and the C1 Pro added the ETM electromagnetic control system, which would intelligently adjust the resistance of the bicycle according to the rhythm of the music under the coach’s preset, and also combined with the user’s day The status is adjusted.

Of course, as one of the implementation paths of the open motion platform, the opening of Keep hardware products will be reflected in the connection of data.

“In terms of hardware, we have also connected to nearly 20 manufacturers, including Huawei, and all data can be interconnected.” said Liu Dong, a partner and vice president of Keep, who is mainly responsible for the sports consumer goods business. “So The current Keep experience, including content and data, has become richer and diversified, and we are evolving towards platformization.”

Keep 3.0 How to commercialize

As a startup company that has recently completed $360 million in Series F financing and frequently reported IPO plans, Keep is obviously no longer the age of storytelling, but has to go to its own sustainable ecology and healthy business model every step of the way. Move closer.

Are content and hardware good business?

The outside world has no way of knowing the scale of Keep’s investment in content research and development and hardware products, but Liu Dong said in an interview that the main investment directions of financing just completed include live lessons, premium content IP, international content IP, and intelligent hardware AIoT.

According to Huang Jingjing, vice president of Keep, the commercial value of content is divided into three levels: the first is to help brands establish communication and contact with users to reduce customer acquisition costs; second, it is part of the service, which can also be said to support The basis of membership scale; third, it can bring brand premiums.

The return on content seems to be difficult to measure at present. The recorded and live broadcast lessons on Keep retain some of the free content and package the rest into membership rights. Although the compound interest of content products is extremely high, it is clear that both rely on users’ recognition of the value of membership rights. How to design Keep’s membership products to continue to attract users is also a difficult point.

In fact, when discussing “value-added business B”, Liu Dong said that it will mainly appear in online forms such as membership and paid courses. The core of this business line is content payment. When the live broadcast class was just launched, this content format was also speculated to be Keep’s touchstone on the road to content payment. However, since the live broadcast class went live in August last year, the commercial form of the live broadcast class is still being explored. It is temporarily related to membership rights. Get through instead of adopting a separate payment model.

“When we evaluate the commercial value of live lessons, we will still return to the origin of sports. For example, we will look at live broadcast data such as the user’s exercise duration to assess whether it helps users exercise.” Huang Jingjing explained, “Live If we did it for less than a year, we still have a lot of gameplay to explore, and we haven’t reached a mature state yet.”

As for the sports consumer goods business, including hardware, although its annual GMV has stabilized at a scale of one billion yuan, it has actually experienced some small disturbances in products such as konjac flour and sports underwear.

Liu Dong said frankly that Keep has also made detours on this commercialization route.

For example, when Keep was making clothing, he noticed that brands like Li Ning and FILA in the entire industry have adopted a sporty lifestyle, which is biased towards a sense of design. This attracted Keep to make the same choice, but the sense of design also means ” Non-standard products”. Looking back, Liu Donghui discovered that not only the sense of design varies from person to person, but also the fault-tolerant mechanism such as the channel capabilities of traditional clothing brands such as Li Ning that Keep does not possess-this may also be the reason for the small bumps.

“So we went back and started from functional clothing again. When you do yoga and running sports bra, you will find that the comfort of the fabric is still relatively standard.” Liu Dong said, “So this is regarded as a consumer product. We have taken a little detour, but we are still able to adjust back.”

It is not difficult to understand that Keep’s sports consumer goods will be a strong cash cow, but because of the low gross profit margin (close to the industry level), it will not become Keep’s main source of profit, satisfying multiple rounds of income generation and high gross profit margin. Payment is a weapon to improve the company’s overall profitability.

In fact, this income structure may also indirectly determine Keep’s strategy for content and hardware at this stage.

Previously, Keep stated that the company had achieved overall profitability in March 2020.

“But whether we want to continue to make profits depends on our future plans.” Liu Dong said, “We believe that we need to make some investment at this stage, because we have already made it clear from the strategic point of view that in terms of platform, content, and smart hardware Going up is to invest in this matter.”
