The post-80s IPO of the University of Science and Technology of China rang the bell: the opening rose 56%, with a market value of 16 billion

On the 27th, Yuncong Technology officially landed on the Science and Technology Innovation Board. The IPO price was 15.37 yuan per share, and the opening rose 56.15%. The market value once exceeded 16 billion.

Behind Yuncong Technology is a post-80s doctor, Zhou Xi. In 2011, Zhou Xi gave up studying in the United States and chose to return to China – to study AI in Chongqing.

Zhuanzhuan will charge a payment channel fee for successful orders, the rate is “six thousandths”

On May 27, the second-hand trading platform Zhuanzhuan announced that starting from May 30, 2022, it will collect “six thousandths” of the payment channel fee for orders successfully traded in the free market.

Huawei mobile phones will add an “Application Security Detection” entry, which can scan mobile phones for illegal applications

Huawei officially announced that the Huawei AppGallery will gradually add “application security detection” entries to various models of Huawei mobile phones, and upgrade the function of application security detection.

The app security detection function can detect and scan all apps installed on the device, including official apps downloaded through the Huawei AppGallery and third-party apps downloaded from other channels.

According to reports, the application security detection system of HUAWEI AppGallery will also issue risk warnings for non-compliant applications downloaded from third-party channels, such as viruses, privacy violations or malicious advertisements, which are found during the scanning process to ensure that users are aware of the application. Safe state. At the same time, the application security detection function is connected to the National Anti-Fraud Center’s fraud information black sample database, and provides early warning and interception of fraudulent applications that users may come into contact with.

In addition, Huawei AppGallery will remove some apps that are safe and compliant at the time of launch, but whose developers use the cloud to control suspected malicious behavior. (Source: IT House)

xMEMS micro speakers will appear in headphones

xMEMS, a company that specializes in making tiny speakers using MEMS technology, demonstrated a 3D-printed model at Computex with an OEM manufacturer called Vencer.

This 3D printed model isn’t amazing looking, and the fit is far from perfect, especially with the foam earbuds installed that don’t create a proper seal for you. So on the show floor, no kind of sound quality judgment can be made, but it seems that MEMS earphones have a lot in common with balanced armatures, that is, they need a good seal to make a good sound.

An interesting aspect of MEMS speakers is that they can be used in both open and closed modes, where open mode would be used for ambient modes such as making phone calls or in place of ANC-enabled type earbuds. The closed mode will work like a pair of normal drivers inside normal earbuds.

There isn’t any specific information on when the retail products will be available, but the manufacturers say they will be available later this year. (Source: cnBeta)

New experiment shows quantum internet is one step closer

The quantum internet is an internet that uses the principles of quantum mechanics to transmit information. Under the quantum Internet, users will be expected to send information on a completely secure communication network.

Recently, a research team from Delft University of Technology in the Netherlands announced that they have successfully achieved quantum information teleportation between two non-adjacent nodes for the first time using a basic three-node quantum network.

This effect, previously reported, has been confined between two connected nodes. This result shows that mankind is one step closer to building a quantum Internet. The research has been published in the May 25 issue of the journal Nature. (Source: Smart Technology Fans)

Ultra-high-definition schematic diagram of China’s space station: the space villa will be completed by the end of the year and can accommodate 6 people

Recently, the official popular science microblog of the Science and Technology Committee of China Aerospace Science and Technology Corporation @ Aerospace Stave released a picture, which has aroused widespread heated discussion among netizens, that is, the ultra-high-definition schematic diagram of the Chinese space station. Officials said that according to the plan, the Chinese space station will complete the construction of the T-shaped configuration by the end of this year, with more than 110 cubic meters of activity space in the cabin.

The interior will be equipped with 2 astronaut exit hatches and 1 cargo airlock, and provide 6 sleeping areas and 2 sanitary areas, which can realize long-term 3-person and short-term 6-person residency, which can be said to be a space villa. According to previous reports, in the overall T-shaped configuration of the space station, the core cabin is an absolute C position, and the experimental cabin I and the experimental cabin II are connected on both sides respectively. Among them, the core cabin will also be used to control the entire space station assembly, and the two experimental cabins are used for scientific experiments in biology, materials, microgravity fluids, and basic physics.

The Chinese space station also uses advanced network communication technology, Wi-Fi is available, and the speed can reach 1.2Gbps, which is the downlink speed of China Tianlian relay station. No. 01 star, connecting the core module and the ground station, the delay is only seconds. In addition to China’s own use, Yang Liwei also said that our country’s manned spaceflight is open to different countries and institutions, and more countries are welcome to join us in conducting space research.
