Right after 110 K, the R(ohm) data points jump randomly between 1E-5 and 1E-7.

I very much doubt that this is due to the accuracy of the instrumentation (rather than the actual change in data points), for which the change should be very gradual as the accuracy reduces down the scale.

That is to say, the randomness should increase slowly from 110 K toward the lower temperature if this is anything to do with the limitation of the instrumentation in measuring the smaller values, rather than the sudden jump to the datapoint randomness right after 110 K shown in the graphs, which is something interesting deserving to be looked into further possibly with better equipment.
Note its a logarithmic graph. If the noise floor is 1E-5 ohms, it would look smooth above 1E-4 ohms, and then would show as randomness once the signal declines below 1E-5 ohms.

So in that case, we cannot say anything about the 1E-7 vs 1E-5 ohms being meaningful.

Those researchers should know the working range of their instruments.

For the graphs to be meaningful, the range from 0.1 to 1E-7 should be within the specifications of their instruments with known accuracy through the range.

If the range of 1E-5 to 1E-7 is outside the specifications, I don't see why they even bother to continue using the instrument that is below the required specifications and continue collecting the data points as though they are valid and making the supposedly scientific conclusions based on those invalid random data points.

China sweeps half of the world's quantum technology patents! The scale of investment is the largest in the world! As of 2022, China's investment in quantum information technology has reached 15.3 billion U.S. dollars.

From the perspective of the number of global patent applications, China is also at the forefront of the world, accounting for 52.3% of patent applications, followed by Japan (13.8%), the European Union (13.8%), the United States (10%), and South Korea (3.6%)..

最近对无人机和反无人机加强管制了。这次我们除了对无人机整机限制外,还对无人机零部件也实施了出口管制,包括对部分无人机专用发动机、重要载荷、无线电通信设备和民用反无人机系统等实施出口管制。
因为我们除了是民用无人机最大的生产国外,我们还是全世界最大、最全的无人机产业链,特别没有中国产业链的零部件,全世界其他地方的民用无人机基本就要歇菜了。因为美国等西方国家,搞什么名为“国家安全”实际市场保护的措施,所以法律限制导致很多情况下不能买中国整机。他们就有一些当地公司买中国零部件组装卖给美国当局,满足法律要求。
所以我们这次限制,可能会导致西方无人机产量大减,价格暴涨。当然这是中国对世界和平的贡献。

超超临界燃煤火电设备不出口了。全世界效率最高、性价比最高的燃煤火电设备就是中国生产的。中国的火电技术极为先进,能效高、尾尘和脱硫脱硝都处于世界前沿水平。可以说,印度、东南亚等如果没有中国廉价超超临界燃煤火电设备支持,什么大规模工业化就是幻想,因为没有工业电就没有工业化。可是现在在国内市场打得头破血流的火电设备,国外要买都买不到了。西方通过碳中和本来是想锁死中国的工业发展天花板,没想到把阿三等发展中国家锁住了。当然,后续如果印度东南亚等有能力开发自己的超超临界燃煤火电设备,那相当于取下脖子的枷锁,不过这个时间不会短。他们只能期望中国绿电厉害,降低石油价格或者出口新能源设备和储能设备给他们了。

中国航母拦阻索也意外横空出世。航母拦阻索以前只有俄罗斯和美国两家能制造,英国和法国买美国的,印度买俄罗斯的;中国辽宁舰也需要配套,但是俄罗斯给的价格实在是高,而且供应速度不够快捷。于是项目专门对航母拦阻索进行招标,几个钢铁巨头一时拿不出来。结果河北有个民营企业发现他们在批量外销的一款完全满足招标要求,项目方拿了产品一测试果然一次通过。令人惊讶的是这个产品是当时外方垫款鼓励研发的,卖了多年了,因为外方从中国买可以大幅降低成本。再后来才知道,据说原来外方拿这个产品做一些加工就是鹰酱家的航母拦阻索了。
也就是说,这个我们民间日常随便卖的产品,居然是美俄控制出口的,他们奇货可居,我们却当普通民品卖了,因为我们产品能力已经强大到物美价廉了。

总体上,中国有越看越多在国内随随便便买卖的东西,到国外却是不可多得的高科技产品,只因为我们科技进步太大,我们都没有感觉了
I must say that the effect of drone sanction will be interesting. Without Chinese supply chain, can the western drone makers produce drones? You want to block DJI drones. Fine, I won't let you have any drone.

Of course in reality, it probably won't work that way, but still will be interesting to see who China ends up blocking

The later part is really interesting.

Like wtf, the arresting gear/chain for US aircraft carriers is apparantly using metal made by a civilian company in China?
If so, it's likely that there's lots of other stuff that might be made by civilian companies to then be exported and used by companies in US, including defense companies lol.

Researchers from the Institute of Process Engineering (IPE) from the Chinese Academy of Sciences and the University of the Chinese Academy of Sciences have developed a design for the an "on demand" whole tumour cell vaccine (TCV).
Please, Log in or Register to view URLs content!
Breaking down this article, the approach taken here is certainly a very novel one and at the very least applicable to a wide range of cancers should the tests done on animal models apply to human patients. Immunotherapy is an emerging therapeutic field and there are certainly many contenders for promising treatments such as mRNA vaccines and oncolytic virotherapies to name a few.

What the researchers do here is take a sample of cells directly from the tumour, inactivate them, and load them with nanoparticles that convert light to heat. They then inject it back in, and the vaccination site is irradiated with an IR laser. This raises the temperature at the site and puts the tumour cells under heat stress, forcing them to overexpress heat shock proteins to adapt to the increased temperature. These proteins act as adjuvants, which increase the immune response to the cells. The raised temperature at the site also creates a mild inflammatory environment, further improving immune activation. Assuming this holds up in human patients, when using this technique you only need one dose of the vaccine itself with periodic irradiation of the vaccination site.

The Ningbo team of the Chinese Academy of Sciences fills the gap in the field of elastic ferroelectric materials! Recently, the research team has developed a new polymer ferroelectric material with both elastic recovery and ferroelectricity. The sensor made of this material will be more easy-going, with higher measurement accuracy and better wearing comfort. In the future or The mobile phone can be soft and close to the body, and can be bent arbitrarily...
