Luxshare respond to false rumors
Recently, Li Xun Precision said through an interactive platform that there are rumors on the Internet that the company's products are unqualified and that customers request returns and compensation, and that the company is laying off a large number of employees. Lixun Precision pointed out that in response to the temporary adjustments of individual factories due to the supply problems of upstream and downstream suppliers during the mass production process, in order to protect the interests of employees and ensure that employees go to work normally, the company will give priority to the existing product line affected personnel to support the company Other factory areas (the relevant welfare benefits will not be affected) are normal work arrangements.

Scientists have discovered a new livable planet
Recently, the Cambridge University astronomy Nikku Madhusudhan, the chief researcher of the institute, and his colleagues have identified a new type of habitable planet-"Hycean", which is a compound word composed of the two words hydrogen and ocean. The researchers pointed out that the radius of Hycean can reach 2.6 times that of the Earth, and the mass can reach up to 10 times that of the Earth, which is much larger than any planet previously considered to be habitable. The researchers also studied the Hycean Habitable Zone, which is a band-like area between the parent star of that allows liquid water on the surface. It turns out that the Hycean habitable zone is much larger than terrestrial planets.

China Science has made significant progress
today meson study singular charm, theAccording to University of Science and Technology of China official Weibo, the high-energy nuclear physics research group of University of Science and Technology of China cooperated with Lawrence Berkeley National Laboratory , Central China Normal University, University of California, Los Angeles and other units. In the RHIC-STAR heavy ion collision experiment with a center-of-mass energy of 200 GeV, it was observed that the yield ratio of strange charm mesons to neutral charm mesons was significantly enhanced compared to proton-proton collisions. The research results show that in the extremely high temperature and high density thermonuclear matter formed in the early days of the Big Bang-quark gluon plasma, there are indeed quark and gluon degrees of freedom, charm quark and strange quarks Cascade is an important way of the strange charm meson Ds hadronization. Combined with the previously published results of the collective flow of D mesons, it provides an important experimental basis for people to understand the collective motion properties of charm quarks and the process of hadronization. The research results were published on " Physical Review Letters " on August 26.
