The United States has begun a study of how to destroy potentially dangerous asteroids with a nuclear device

A new study by Lawrence Livermore National Laboratory (LLNL) and the Air Force Institute of Technology (AFIT) is investigating how the neutron energy generated by the explosion of a nuclear device can deflate an asteroid. Scientists compared the two different neutron energy source (fission neutron nuclear fusion neutron) asteroid deflection caused by the parallel comparison to these two kinds of neutron energy source, the purpose is to know the nuclear blast which neutron energy released is more advantageous to the asteroid deflection, and revealed the reasons, lay a foundation for optimizing the asteroid deflection effect. The new study, published in a recent issue of the Journal of American Astronautics, was led by Lansing Holland as part of the Planetary Defense and Arms Export Project with LLNL Lab while he was a graduate student in nuclear engineering at AFIT. "The team focused on neutron radiation from nuclear explosions. Because neutrons are [...]

R & D director of Audi China: Huawei's automatic driving scheme may be adopted

During the Shanghai auto show, Audi released three new heavy weight vehicles, namely, q5l, a7l and a6e-tron concept vehicles. Among them, a6e Ron, built on the pure power platform of PPE, is the most attractive, adopting a new design language, which will last more than 700 kilometers, and will be listed in 2023. After Audi's new product launch, michaelhofmann, executive vice president of Audi China R & D, said it introduced the reasons why Audi cancelled the L3 level autopilot project and the cooperation with Huawei in the field of autopilot. 1. Audi may be equipped with Huawei autopilot Technology Just before the opening of this auto show, the car and things were invited to experience Huawei ads high-level automatic driving scheme system, and was impressed by its urban self driving ability. After the experience, Huawei's president of intelligent driving product line said that a large European brand has signed [...]

Huawei publishes relevant patents on automatic driving, and the conflict between automatic driving behavior and driver's driving intention can be solved

Huawei publishes relevant patents on automatic driving, and the conflict between automatic driving behavior and driver's driving intention can be solved Recently, HUAWEI has added a number of patent information, including "an adaptive optimization method and device for autopilot" patent. It is reported that the patent relates to the field of automatic driving technology, which solves the problem of conflicting driving behavior and driving intention of vehicles under the control of automatic driving system, and can be applied to smart cars and connected cars. ] The patent summary shows that the patent specific plan is: the automatic driving device acquires the driver's driving intention of the target vehicle (step 501); based on the driver's driving intention, the automatic driving device detects that there is a conflict between the driving behavior of the vehicle under the control of the automatic driving system and the driver's driving intention (step 502); the automatic [...]

Nvidia will release a new version of the Ampere GPU

NVIDIA's attitude towards graphics card mining seems to be getting tough. In the past, it was ambiguous about mining, suggesting that it would not be suppressed. Now NVIDIA is going to play an important role, and RTX 30 series graphics cards may be upgraded to block mining performance. Previously, we have reported that the RTX 3060 graphics card will upgrade the new GPU core ga106-302-a1. This time, it will shield the mining performance and block the hardware. Two days ago, it was reported that the RTX 3080 Ti to be released soon would be the same. The core code of the new graphics card received by the manufacturer is ga102-202 or ga102-302, which is different from the previous QS version. These new cores are different from the original GPU cores. They use different hardware IDs and can't brush firmware with each other, thus avoiding the possibility of driver cracking. RTX [...]

International Space Station scrapped Russia: I'm going to quit and go it alone

As the word "international" in the name says, the international space station is a large project jointly built and maintained by more than ten countries in the world. In addition to the familiar us, Japan, Canada and Europe, Russia is also one of the five major member states. However, with the aging of the international space station, some member states have begun to plan for a "back road". Russia recently announced that it will withdraw from the international space station and intends to work alone. It's right to learn from China. You can do it yourself without being restrained. Russian Deputy Prime Minister Borisov said that considering the serious aging of the international space station (ISS) and the expiration of the space station operation contract in 2024, Russia plans to withdraw from the project and start building its own space station from 2025. Borisov's "aging" theory is indeed a fact. [...]

Scientists discover brain hunger switch

The researchers claim that they have discovered "the mechanism of the brain hunger master switch". Researchers from the Hebrew University of Jerusalem and the Weizmann Institute of science, working with their British counterparts at Queen Mary College, University of London, have made a breakthrough in weight loss. According to a press release, the researchers involved in the study published their research results on the 15th, revealing that "the mechanism of action of the master switch for controlling hunger exists in the brain", which is confirmed to be melanocortin 4 receptor (MC4 receptor). The switch can also be triggered by a drug called "semeratide" that can be used to treat obesity, the report said. According to reports, MC4 receptors give instructions to our bodies, making us feel full and eliminating our desire to eat more food in a certain period of time. Any mutation in the brain that causes the MC4 [...]
