iPhone's 80 percent components/Parts manufactured in Mainland. unbelievable

so world's most valuable company is basically Chinese. LOL

people always talk about C919 have many western parts. but they just ignore how much Apple dependent on Chinese supply chain. same thing with other Global high tech firms. Siemens sourced 80 percent components/parts for their high end CT/MR scan machines from China. soon they will open second assembly line in Shenzhen.

But all the dependencies they have on China are low tech stuff they can easily get in other third world countries…

People focus on dependencies on Western components because only the West regularly weaponizes supply chain dependencies. Any time you're dependent on them for anything, they'll treat it as a license for sanctions. This is why the world must eliminate its dependence on the West; take away their leverage and their power will follow.

As a research power house, China will play a key role in that process. Now it just has to convince the rest of the world to follow its lead.

China leads the world in integrating 5G into economy: experts

Four years after China issued 5G commercial licenses to domestic companies, 5G applications have emerged in nearly 60 percent of the nation's economic categories, with wide coverage of 5G networks and application of 5G solutions in major industries, media reports said. Experts noted that China leads the world in integrating 5G into the real economy.

According to a CCTV report on Tuesday, China has built the world's largest 5G network with the most advanced technologies. As of the end of April, the nation had more than 2.73 million 5G base stations, with 5G networks covering all prefecture-level cities and county-level urban areas. More than 600 million households had used 5G mobile phones.

"So far, 5G applications have been integrated into about 60 of the 97 national economic categories, with more than 50,000 applications launched. China's telecom industry has invested nearly 600 billion yuan ($84 billion) to construct the 5G network, directly driving total economic output of about 3.8 trillion yuan and indirectly generating output of about 9.4 trillion yuan," the report noted.

Huge efforts have been made to apply 5G to industries, and 5G application solutions in key industries such as mining, ports and power were "widely copied" to help companies conduct their digital transformations.

In 2019, China issued 5G licenses to the three major telecom operators and China Broadcasting Network Corp.

Experts praised authorities' and industries' efforts in pushing 5G applications, saying that China's 5G layout tops other countries.

"No matter whether in terms of base station scale, user scale or the business-to-business sector, Chinese operators are the global leaders and have met market expectations in general," Yuan Bo, a senior telecom engineer, told the Global Times on Tuesday.

Many media reports said that China's speed of setting up 5G base stations is much faster than that of the US. The Wall Street Journal in early 2022, for example, showed that China had installed more than 1 million 5G base stations, while the US built only about 100,000.

Another highlight of China's 5G application is in industry, where the technology has brought revolutionary changes, such as remote control in mining and engineering companies, automatic operation in ports and automated inspection of core facilities and sites, Ma Jihua, a veteran industry analyst, told the Global Times on Tuesday.

Moreover, a number of 5G industrial parks have been set up in cities such as Shanghai and Dalian in Northeast China's Liaoning Province. The first 5G Internet of Things industrial park project in Northwest China's Xinjiang Uygur Autonomous Region is expected to be completed next month, according to media reports.

Experts stressed that China's 5G application still has room for development and progress. Yuan said that 5G's value needs to be further explored in the business-to-customer sector.

Officials revealed that the country has planned to further push forward 5G development. Industry and Information Technology Minister Jin Zhuanglong said during a recent exhibition that China will speed up the construction of virtual private networks in the 5G industry and enrich the country's 5G application scenarios.

He also said that China will improve the coverage of high-quality networks such as 5G and gigabit optical networks by continuously optimizing the infrastructure and building 5G factories.

Quite impressive stuff

important part to consider
华为数据通信产品线副总裁邱月峰表示,中国算力发展指数白皮书显示,预计2023年智能算力占比将高达70%, 以ChatGPT为代表的AI大模型参数量将增长115倍,预计2030年AI算力将增长500倍。海量数据来袭,数据中心需要超强悍性能的设备来构筑行业智算“高速公路”。本次发布的业界首款800GE数据中心核心交换机CloudEngine 16800-X系列,基于三个X能力,具备业界最高密288×800GE端口数量,可高效支撑AI训练等业务,100%释放算力。
you need information highway to be wider and faster to support the amount of data that will come through.
If other countries don't want to buy Huawei technology. That's fine. They will just fall behind and while their GPUs are sitting idle waiting for data

There is no immunochips based allergies detection technology in China?

Please, Log in or Register to view URLs content!

General Electric, Siemens, Drager, Toshiba, Philips - these companies still account for about 70% of medical equipment in Russia. For more than a year, dust particles are literally blown away from it. Manufacturers have closed local offices along with maintenance services, while some blood test machines, such as those from Siemens, work only on native reagents.

Against this background, suppliers say, the demand for Chinese analogues has grown. At the same time, the performance and range of tests for systems from China are more modest, said Dmitry Slavashevich, CEO of the Algimed supplier company:

“A striking example is allergology. There is technology on immunochips of the American corporation Thermo Fisher Scientific, but they also stopped all shipments. There was a panel that contained about 113 indicators for determining allergies not in general, for example, to cats, but to a particular breed, or not just to birch, but to certain types of it.

The Chinese have no such analogues, since this player is a monopolist. In principle, all patients in Russia who suffer from allergies are left without such an advanced level of diagnostics.”

Adaptive and maladaptive introgression in grapevine domestication​

Abstract​

Domesticated grapevines spread to Europe around 3,000 years ago. Previous studies have revealed genomic signals of introgression from wild to cultivated grapes in Europe, but the time, mode, genomic pattern, and biological effects of these introgression events have not been investigated. Here, we studied resequencing data from 345 samples spanning the distributional range of wild (Vitis vinifera ssp. sylvestris) and cultivated (V. vinifera ssp. vinifera) grapes. Based on machine learning–based population genetic analyses, we detected evidence for a single domestication of grapevine, followed by continuous gene flow between European wild grapes (EU) and cultivated grapes over the past ~2,000 y, especially from EU to wine grapes. We also inferred that soft-selective sweeps were the dominant signals of artificial selection. Gene pathways associated with the synthesis of aromatic compounds were enriched in regions that were both selected and introgressed, suggesting EU wild grapes were an important resource for improving the flavor of cultivated grapes. Despite the potential benefits of introgression in grape improvement, the introgressed fragments introduced a higher deleterious burden, with most deleterious SNPs and structural variants hidden in a heterozygous state. Cultivated wine grapes have benefited from adaptive introgression with wild grapes, but introgression has also increased the genetic load. In general, our study of beneficial and harmful effects of introgression is critical for genomic breeding of grapevine to take advantage of wild resources.

我国葡萄育种技术取得新突破,将推动国内葡萄酒从进口转出口​

北京时间6月6日,《美国国家科学院院刊(Proceedings of the National Academy of Sciences, PNAS)》在线发表了中国农业科学院深圳农业基因组研究所周永锋课题组在葡萄群体遗传学与育种领域的最新研究成果“Adaptive and maladaptive introgression in grapevine domestication”(葡萄驯化过程中适应与不适应的基因渐渗)。

目前,作物育种技术已发展到4.0阶段(全基因设计育种),即在育种过程中选择性的快速聚合有利变异、移除有害变异,从而达到快速高效育种的目的。然而现代育种技术在葡萄育种过程中的应用十分有限,葡萄育种暂时还停留在2.0阶段,主要原因是缺乏基因参考信息,仍依赖于大规模杂交筛选育种。

我国拥有丰富的野生葡萄资源,葡萄属下70多个种中我国就有近40种。如何充分利用这些野生葡萄的丰富基因资源、加快落实现代育种技术的应用和培育优良葡萄新品种是现阶段最主要的葡萄育种目标和策略,具有巨大的商业潜力。

该研究成果首次利用机器学习手段结合群体遗传学分析方法揭示了野生葡萄渐渗对葡萄风味的形成的重要影响,解析了驯化对葡萄基因组的影响,进一步阐明了葡萄的驯化历史。是葡萄育种领域的又一重大突破,为现代育种技术在葡萄中的应用提供了重要的理论支持。

此外,当下无论鲜食还是酿酒的主流葡萄品种多为国外选育品种,我国的葡萄酒市场尤其是高端葡萄酒市场长期被西方的进口葡萄酒所占据,培育具有我国自主知识产权的优质葡萄品种,具有重要的战略和商业价值。该研究成果将有助于推动我国实现从葡萄酒进口国转为出口国。
