Huawei's 5G foldable phones propelled it to the top spot in the world in the first quarter.

Huawei overtakes Samsung as top foldable-phone maker​

New 5G capable Mate X5 wins fans in China

Huawei Technologies has overtaken Samsung Electronics as the world's leading manufacturer of foldable smartphones, seizing the top spot for the first time with a boost from its new 5G models.

China-based Huawei accounted for 35% of foldables shipments in the first quarter, up 21 percentage points on the year, according to Hong Kong-based Counterpoint Research.

Samsung's market share shrank 35 points to 23%. Honor's share shot up to 12%, putting the Chinese company in third place.

Changchun Institute of Optics, Fine Mechanics and Physics' domestically produced optical design software - Changguang Stray Radiation Analysis Software V1.0 official version is officially released!​


Zhang Xuejun, academician of the Chinese Academy of Engineering and director of the Changchun Institute of Optics, Fine Mechanics and Physics, personally explained the core functions and uses of this optical software. Many leaders and academicians visited the booth for guidance and exchanges.

Changguang stray radiation analysis software is a large-scale optical engineering software that uses ray tracing methods to simulate the stray radiation of optical systems. It has core functions such as three-dimensional solid optomechanical modeling, light source modeling, surface property modeling, ray tracing, and stray radiation analysis. It can be used for simulation and analysis of high-end optical systems in aerospace, aviation, security, medical, electronics and other fields.

The optical software R&D team is composed of relevant personnel from the Key Laboratory of Advanced Manufacturing of Optical Systems (Chinese Academy of Sciences) and the Advanced Computing and Digital Engineering Research Center of Changchun Institute of Optics, Fine Mechanics and Physics. The team size is about 40 people, and this is a research team with an average age of only 33. During the development process, the team overcame many difficulties and made breakthroughs in the core key technologies such as the measurement and characterization technology of the luminous properties of light sources, the scattering properties of optical and mechanical components, the ray tracing and splitting technology based on the Monte Carlo method, the stray light data recording scheme and the path classification method. The team has fully mastered the underlying core algorithms, has independent intellectual property rights, and has excellent core technical indicators, contributing to the realization of my country's optical software autonomy and the localization of industrial software.

According to this report, China is 10-15 years ahead of US in the construction of 4th generation nuclear reactors, and China is planning to build 150 nuclear power plants by 2035.

US as many as 15 years behind China on nuclear power, report says​

...
China has 27 nuclear reactors under construction with average construction timelines of about seven years, far faster than other countries, said the study by Information Technology & Innovation Foundation, a Washington-based nonpartisan research institute.

The 10-15 years estimate is probably based on the fact that China has a 4th gen reactor operational right now, and that it would take the US about 10-15 years to construct a nuclear reactor. The problem is that there is no nuclear reactor under construction in the US right now as far as I know, so every year goes by would add a year to that estimate.

Not to mention that they are not even keeping up in the competition for next gen designs. Even if/when they eventually build something, it'll be backwards and a huge national safety liability compared to what China is building.

I think there was a very short hype moment going on with small modular reactors some years ago in the west.
I don't think they ever did anything with that hype. But maybe it will be needed for new server farms US big tech want to build for AI training.

There's a very recent article from Bloomberg on this.

Note that the TerraPower reactor (Natrium) they're talking about has started construction only on the non-nuclear portion of it, so it remains to be seen what the timeline for it may be. It should be relatively low risk though, as there have been operational commercial scale sodium cooled fast reactors since the 70's.
