With this success, he has helped nearly 20% of the world’s population escape hunger and contributed to making China one of the world’s leading rice producers,” said Minister of Agriculture and Rural Development Le Minh Hoan. First letter of condolence, sent on May 23, 2021, to the family of the late Professor, Academician Yuan Longping and the Chinese agricultural industry. Mr. Yuan Longping was born in 1930, is China’s leading agricultural scientist on hybrid rice. He and his colleagues have contributed to bringing rice yield from 4.5 tons/ha to 15 tons/ha. This is considered the key to helping China solve the food security problem for more than a billion people in this country. Thanks to the late Professor Vien Long Binh, hybrid rice has been replicated throughout Africa, America and Asia. In Vietnam, the first generation of hybrid rice that was put into wide production was the variety Bac Uu 64 (also known as Tap Giao 4 – TG4), starting in the early 1990s. Thanks to this variety, along with the following varieties. such as San uu 63 (called Tap Giao 1), San uu Que 99 (Tap Giao 5), Vietnam has stabilized domestic food. After nearly ten years of access, our country has self-produced high-quality hybrid rice varieties such as HYT100, HYT 57, LC2, LC3, especially VL20 and TH3-3. However, the pioneer in the development of hybrid rice still belongs to the late Professor Vien Long Binh. Minister Le Minh Hoan continued: “In his working life, Professor, Academician Vien Long Binh has visited, worked, and supported projects/programs on hybrid rice many times, and trained staff. Research and technology transfer for Vietnam’s agricultural industry These are solid agricultural scientific foundations, gradually contributing to poverty reduction, ensuring food security and creating an export miracle. rice export of Vietnam”. At the end of the letter, Minister Hoan expressed his gratitude to the man who is considered the father of hybrid rice: “In the face of infinite grief, on behalf of Vietnam’s agricultural industry and in my personal name, I would like to send to the whole family of Mr. and the Chinese agriculture industry deeply condolences for this great loss and grief.”

Samsung Display’s dominance is being threatened by Chinese companies In particular, when Apple adopted OLED panels instead of LCD panels starting with the iPhone 12 series in 2020, the use of OLED panels increased sharply. Recently, Chinese display companies are entering the small and medium-sized OLED panel market, increasing the supply of low-cost panels. Omdia estimates that Apple will use the largest number of OLED panels for smartphones next year. It is expected that Apple will use 169 million OLED panels in 2021 and 190 million panels in 2022. Most likely they will use OLED panels for new products expected to launch in the second half of 2021. Meanwhile, Samsung is also expected to use 155 million OLED panels in 2021 and 168 million panels in 2022, the second largest after Apple. Although Samsung Display is expected to maintain its No. 1 position in the global smartphone OLED display market next year, its market share is expected to shrink due to competition from other manufacturers. Chinese company. In fact, according to Omdia, Samsung Display’s market share has dropped from 86% in 2019 to 78% in 2020. Omdia forecasts that its market share will drop to 77% in 2021 and 65% in next. On the other hand, the market share of Chinese companies is expected to increase from 15% in 2021 to 27% in 2022. In particular, BOE, China’s largest display manufacturer, is expected to expand the market. share from 6% in 2021 to 13% in 2022. Regarding this, Omdia said: “Chinese display companies are improving their technical skills. China will be a major threat to South Korea’s leading position in the OLED display market.” Phan Van Hoa (according to Businesskorea)

The technology giants like Amazon, SpaceX, OneWeb continuously pour money to invest in satellite Internet. Photo: TechCrunch In recent years, satellite broadband is becoming an increasingly popular way to connect to the Internet. Major space companies are also in the race to build ultra-high-speed Internet services through orbiting satellites. Now, the field is forming a model similar to the “Seven Warring Heroes”. The companies are all moving towards a common goal: competing to be the biggest brand in broadband satellite and SpaceX’s position with Starlink dominance is being challenged. SpaceX’s Starlink project SpaceX boss – Elon Musk Of all the companies, SpaceX is the one involved with the most satellite launches. Its Starlink project has more than 1,350 satellites in orbit and plans to launch 42,000 satellites by mid-2027. Eventually, SpaceX hopes to have thousands of satellites around the Earth to establish a global network. Starlink’s Beta “Better than Nothing” was launched last October and attracted more than 10,000 users in six different countries. Starlink’s business model connects customers directly with satellites without the intervention of telecom companies between the two parties. Users register for Starlink service through the website. Once the order is accepted, Starlink will send the hardware set to the customer, which includes a tripod, WiFi router and satellite antenna. Monthly subscription fee is $ 99, and maximum download speed can reach 210 Mbps. Starlink is expanding rapidly and plans to install antennas on vehicles and connect them to satellite networks. According to the test of Internet analytics service developer Ookla, the download speed when using SpaceX’s satellite Internet is 95% faster than the normal Internet in the United States. Project Kuiper from Amazon The Amazon project is named Kuiper In 2018, Amazon’s Kuiper Project was revealed. At that time, government documents showed that the tech giant was working to build global space-based Internet services. The goal of the project is to launch 3236 satellites into a 630 km long orbit, very close to the 550 km altitude of the Starlink satellite. In January of this year, the US Federal Communications Commission approved the Kuiper Project to launch Amazon satellites into space before July 2029, and connect them to antennas on Earth to provide translation. Internet service. As of July 30, 2026, 50% of the project’s satellites will operate. Like Elon Musk, Jeff Bezos, the boss of Amazon, also owns a private rocket and space service company called Blue Orgin. Although no specific plans have been announced, the company is believed to be in charge of bringing the Kuiper satellite into orbit. OneWeb The Soyuz-2.1b carrier missile carries 36 OneWeb satellites that take off from the launch pad of the Vostocini launch pad. OneWeb is a UK owned broadband satellite provider. It currently has 146 satellites in orbit, 1,200 km from the ground and plans to launch a total of 648 satellites to provide global Internet service. In November last year, the company got out of bankruptcy thanks to the British government and India’s Bharti Group. OneWeb hopes to provide Internet services to the entire UK by June. Its latest service will cover the highest latitudes in the world, including Alaska, Canada, Greenland, Russia and Nordic countries. This British company provides a B2B model, provides satellite Internet to telecom companies, then the telecom companies deliver services to customers. Both SpaceX and OneWeb launched satellites into space on March 25, clearly showing a race between the world’s two leading powers in space technology. Hughes Net Satellite team Hughes Jupiter 2 Hughes Net is the largest satellite Internet provider in the United States. It relies on geostationary orbit (GEO) satellites 36,210 km away to transmit the Internet back to earth. The main difference between a satellite operating in low Earth Orbit (LEO) and a geostationary satellite is that GEO satellites can cause delays in video calls and public calls. other technology. However, the GEO satellites are in a fixed position, so unlike LEO satellites, they will not travel in orbit but target a specific area. The Hughes Network has more than 1.5 million users and six satellites in orbit, covering different areas of North America, South America and Canada, including Mexico, Brazil and Chile. The last satellite that Hughes launched was in June 2018 and its goal is to put another satellite, called Jupiter 3, into orbit by the second half of 2022. It is said that this will be a commercial satellite. the biggest ever. Hughes’ satellite service costs range from $ 59.99 to $ 149.99 per month and download speeds of 25Mbps. The kit is priced at $ 249.99, and the installation costs $ 199. The company also offers public WiFi hotspots for rural Latin America for people who cannot afford subscription fees. Telesat Daniel Goldberg, CEO and President of Telesat, Canada’s satellite operator Telesat has 15 GEO satellites at an altitude of 35,000 km above Earth. The company also plans to build an LEO Internet called “LightSpeed”. The first 298 satellites built by Thales Alenia Space are scheduled to launch in early 2023 and provide global services by 2024. According to reports, Goldberg confirmed at the 2021 LEO Satellite Digital Forum on April 6 that the LightSpeed ​​project would cost $ 5 billion. This is much cheaper than the projects of SpaceX and Amazon, which are more than $ 10 billion. Goldberg recently stated that Telesat has the best pricing in the market. In 2019, Telesat signed a launch agreement with Blue Origin to use New Glenn rockets to send LEO satellites into orbit. David Wendling, Telesat’s chief technology officer, revealed that the company has three other startups underway. ViaSat ViaSat application on smartphone ViaSat is headquartered in California, USA, operates five GEO satellites at an altitude of about 35,000 km from the Earth’s surface. The company will put three extremely powerful GEO satellites into orbit by the beginning of 2022 and achieve globalization goals until 2023. ViaSat also plans to put 288 satellites into orbit LEO by 2026. ViaSat executive chairman and co-founder Mark Dankberg said the GEO and LEO satellites would complement each other. ViaSat is working hard to create a “multi-orbit satellite Internet where users can seamlessly use GEO satellites and LEO satellites.” In December 2020, Viasat asked the FCC to study Starlink’s potential environmental impact. In response, Musk wrote on Twitter: “Obviously, Starlink is a ‘threat’ to Viasat’s profits.” Eutelsat Eutelsat is Europe’s satellite operator with 39 GEO satellites at an altitude of 46,000 km. The company now provides Internet services to the regions of Europe, Africa and the Middle East, and plans to launch another satellite called Konnect VHTS to cover the rest of Europe. Michel Azibert, Executive Vice President of Eutelsat, said: “Konnect VHTS will change the rules of the game and allow Eutelsat to seamlessly deliver powerful Internet services to users at prices comparable to the above operators. ground.” Azibert says Eutelsat’s satellite service “is much lower than Starlink, very well suited to the rural markets we’re targeting in Europe, the Middle East and Africa.” Eutelsat was founded in 1977 and launched its first satellite in 1983.

According to Defense World, the US Air Force recently announced blueprints for a new fighter jet being developed under the “Next Generation Aviation Advantage” (NGAD) program, which includes including unmanned and manned fighters.

The image shows a triangular flying fighter and its aerial weapons on display as well. The configuration of this fighter is also very different from today’s fighters, the plane is relatively flat, triangular seen from above, has a pair of vertical V-shaped tails and the air intakes located above. fuselage.

The photo shows that this fighter jet has very highly modular characteristics, can quickly replace engines, landing frames … thereby reducing the load of logistics maintenance, missile pods inside. The aircraft is also equipped with a variety of missiles.

The NGAD program was originally proposed as a joint project of the US Air Force and Navy. Although there is still some joint cooperation between the two sides, each side has in turn set up independent offices to research and develop next-generation fighters.

From 2019 to 2025, the budget for the NGAD program of the US Air Force is 9 billion USD, of which the budget for the fiscal year 2021 is 1 billion USD and the budget of the fiscal year 2022 is 1.5 billion USD.

According to the report, the NGAD program aims to complement the F-22 and F-35 fighters, creating a system with multi-domain cognitive capabilities, flexible information and strong operational advantages. air raid attack. The program will apply digital technology to large-scale fabrication and replacement of small components.

This approach is based on the automotive industry’s digital transformation and uses models to solve design, assembly, maintenance and repair issues before, the Air Force said. build a physical system.

The US Air Force report did not specify the cost of the project to build the aircraft. However, the report mentions that a mysterious jet under the project was tested in 2020, and it is still unclear whether the plane is manned or not.

“We have built and tested a new aircraft and broke all aircraft records,” said Will Roper, Assistant Secretary of the Air Force for US logistics and technology equipment procurement. fight. We are now ready to build the next generation aircraft in an unprecedented way. “

Some previous reports suggested that the NGAD program plane will have an artificial intelligence co-pilot, maybe even the ARTU system (artificial intelligence system built by algorithm to play chess. ).

The artificial intelligence system will act as a support for true pilots, but the weakness of AI systems lies in their logic, while actual military actions may not obey this logic. Human presence is then required to make a decision in unusual, non-standard situations.

It is known that from March 2018, the US Air Force Laboratory has released the image of the next generation F / X aircraft, showing that this aircraft will have a stealth design, eye-catching appearance with laser. High energy capable of cutting enemy aircraft in half.

This is also the main aircraft in the NGAD program, also known as the Penetration Jet. The future F / X aircraft is expected to have longer range and payload, as well as the ability to carry hypersonic weapons.

Under the NGAD program, the US Air Force advocates to exploit advanced capabilities of the new generation of aircraft such as air combat systems linked to fighters, drones and networking platforms. . With the aim of increasing air superiority, the F / X fighter program offers significantly enhanced stealth and works closely in coordination with the drone.

Until now, all information about the capabilities of the F / X is still a military secret. If the program progresses at a rapid rate through streamlined processes and uses current technology, the new generation fighter could join the US Air Force earlier than expected in 2030. .
