This is not same people who complain endless about China copy IP without paying? So now we have a Chinese company willing to pay for the use of an UK university patents and the UK government says no. When the Chinese company inevitable develop a similar technology and the Manchester university sues for patent infringement, the Chinese company should respond "well we wanted to pay you but your daddy say we can't"

China is making progress in decreasing land degradation.

"Total area of degraded land in the Yellow river highland had about 450,000 sqkms at the peak since start of monitoring. It has now been reduced to 23,4200 sqkms, as measured in 2020."

水利部方面表示,从不同区域的特点看,我国东、中、西部水土流失面积均呈减少态势。京津冀地区、长江经济带、黄河流域生态保护和高质量发展规划区等重大国家战略区域水土流失状况继续好转。如黄河流域黄土高原地区的水土流失面积,已经由有监测以来最严重时的45万平方公里减少到2020年的23.42万平方公里,减少了近一半,主色调已由“黄”变“绿”。

"In all the degraded land, 1.1 million sqkms, or 41.35%, are caused by water erosion. The other 58.65%, or 1.57 million sqkms are wind erosion."

监测表明,在全国水土流失面积中,水力侵蚀面积为110.58万平方千米,占水土流失总面积的41.35%,风力侵蚀面积为156.84万平方千米,占水土流失总面积的58.65%。

"In 2021, total land area of water erosion decreased by 1.27%, or 14,200 sqkms compared to the previous year. In the same period, wind erosion dropped by 0.27%, or 4,300 sqkms."

数字显示,2021年,我国水力侵蚀面积较2020年减少1.42万平方千米,减幅1.27%;风力侵蚀面积较2020年减少0.43万平方千米,减幅0.27%。大江大河流域水土流失状况均呈好转趋势。

据中国农业科学院作物科学研究所消息,7月22日,《科学(Science)》杂志以研究长文的形式在线发表中国农业科学院作物科学研究所作物耕作与生态创新团队研究成果。科研团队从碳-氮协同调控作物产量出发,鉴定到水稻中一个重要转录因子OsDREB1C,发现该转录因子可同时提高水稻光合作用效率和氮素利用效率,显著提高作物产量。此外,OsDREB1C可使水稻提前抽穗,实现高产早熟。
在该项研究中,研究人员从光合碳同化和氮素吸收利用协同调控产量出发,在水稻中鉴定到一个同时受光和低氮诱导表达的转录因子OsDREB1C。研究发现,OsDREB1C基因过表达植株较野生型光合碳同化速率显著提高,在光下生长速度更快,并且叶片中积累更多光合同化产物,籽粒灌浆速率加快。同时,过表达植株对氮素的吸收转运能力增强,并能将更多的氮素分配到籽粒中,氮素利用效率显著提高。大田氮肥试验表明,在不施用氮肥条件下,OsDREB1C过表达植株产量已达到甚至高于野生型施用氮肥条件下的产量水平,实现“减氮高产”。此外,研究还意外发现,过表达OsDREB1C可使水稻抽穗期提前,并缩短整个生育周期。

通过2018年至2022年间在北京、三亚、杭州的多年多点田间试验发现,在水稻品种“日本晴”中过表达OsDREB1C基因,较野生型可实现水稻显著增产,产量提高41.3~68.3%,收获指数提高40.3~55.7%,抽穗期提前13~19天;在栽培稻品种“秀水134”中增强表达该基因,较野生型产量提高30.1~41.6%,同时收获指数提高14.8~15.7%,抽穗期至少提前2天。OsDREB1C实现高产早熟的基础在于其光合效率和氮素利用效率的协同提高,在营养生长阶段快速地生长以积累足够多的生物量,在生殖生长阶段将大量的碳氮同化产物分配至籽粒中,最终使产量显著提升。
此外,研究人员还在普通小麦品种(Fielder)以及模式植物拟南芥(Col-0)中进行了多物种验证,发现在小麦中增强表达后可使小麦田间增产17.2~22.6%,早熟3~6天,说明该基因在不同作物中均具有提高产量、促进提前抽穗的保守性功能。

Want a good laugh? Watch this forum of panic over Chinese technology. They don't really talk about technology. It's just the US, EU, and India ranting to figure out how they're going stop Chinese technological independence which is all about to them denying themselves from China. They talk about how they wrongfully helped China to being a technological behemoth but somehow they aren't when it's supposedly their technology. Why is India even a part of the conversation? The guy here is so spirited because he knows India is wholly dependent on the West on them pushing China down for them because that's the only way India can surpass China and not by raising itself up. What's the problem over AI and fintech? They will have theirs and China will have theirs. That's what's the problem is because they want China to have theirs also but as Gordan Chang just said Chinese independence is a malicious act against the West. They talk about regulation because they want China to follow their regulations so that the West will always be in control. European governments have compliance departments solely to make sure they follow what the US commands. They think China is suppose to have one too. As usual when you cutoff all the bull, when the West talks about freedom, it's only about their freedom not anyone else's. By their logic Hitler was a freedom fighter because I'm sure he believed in his own freedom too and not anyone else's if that's all it takes.

Or maybe that’s the only way, you know, they can contribute.

Recently CVPR, one of the two most prestigious conference in "machine vision" was held at New Orleans. China had almost half of the accepted papers. CVPR2022.jpg

Last time when the conference was held in person in 2019 at Seoul

Sensetime is probably the world's greatest computer vision company. Megvii is also a serious company.

Dat's because China bribed them into accepting junk research.

In this conference, a Korean team was found having pirated others' works in their paper that was selected for oral presentation. It painted a big black mark on face of this prestigeous event.

(观察者网讯)据韩媒《朝鲜日报》6月27日报道,韩国首尔大学人工智能(AI)团队23日在2022年全球计算机领域顶级会议CVPR上展示了其入选CVPR“Oral”(接收率为4-5%)的研究成果,结果第二天(24日)就被指剽窃了其他10余篇论文,有的内容甚至“一字不差”地照抄。

Screenshot of the paper by the Koreans:

This anonymous tweeter user exposed the theft.

The whistleblower made a video that compares the Korean paper, paragraph by paragraph, to the original papers which the Koreans copied from.
