丈母娘看女婿

快科技8月23日消息，日前，第二届世界人形机器人运动会在北京国家速滑馆开幕，80台加速进化Booster T2人形机器人集体亮相开幕式，上演大规模全自主群体协同。加速进化强调，场地内没有标记线，也没有操作手拿着遥控紧随其后。         Medicine File photo: VCG
China has granted marketing approval of its first drug for the prevention of acute mountain sickness, filling the long-standing gap in the domestic market where no such medications had been available, Science and Technology Daily reported on Tuesday.
The National Medical Products Administration (NMPA) has approved the marketing of acetazolamide sustained-release capsules, the report said. As the first specialized drug in China indicated for preventing of acute mountain sickness, its approval marks the end of the country's lack of dedicated preventive treatment for altitude illness. 
By inhibiting the activity of carbonic anhydrase, acetazolamide promotes the renal excretion of bicarbonate, corrects respiratory alkalosis caused by hypoxia at high altitudes, thereby regulating acid-base balance, optimizing respiratory status, elevating blood oxygen levels, and reducing the risk of onset at the source. 
In contrast to health products that only provide auxiliary regulatory effects, this medication has been validated through stringent clinical trials and stands as a specialized drug approved by the NMPA with a clear indication for prevention, said the report.
Led by principal investigator is Luobu Gesang, a deputy dean of the People's Hospital of Xizang Autonomous Region, the clinical trial was designed by his team and has yielded critical evidence to inform prevention strategies for altitude sickness that are specifically adapted to Chinese and Asian populations. 
"Previously, although acetazolamide had already been used internationally for the prevention of acute mountain sickness, China had long lacked an NMPA-approved acetazolamide formulation supported by rigorous clinical trials. Furthermore, the existing international formulations were short-acting tablets requiring multiple daily doses, and no drugs with the relevant indication were available on the domestic market for an extended period," said Luobu Gesang.
The sustained-release capsule approved this time not only fills this critical gap but also optimizes the dosage form, providing more reliable and convenient medication protection for the physical health and life safety of people entering high-altitude areas, he added.
Clinical trials showed that, compared with the placebo group, the incidence of acute mountain sickness in the medication group was significantly reduced, with the incidence of moderate-to-severe acute mountain sickness decreasing by 14.6 percent, according to the report.
Related research has been published in the international flagship journal of high-altitude medicine, High Altitude Medicine & Biology.

三 | 加速进化表示，80台机器人均搭载2070 TFLOPS端侧算力，在没有中央指挥的情况下，各自进行独立决策、实时协同并自主抵达指定位置，最终完成整个图案编队。按照单台2070 TFLOPS算力计算，80台T2同时行动的总算力约为17万TFLOPS，相当于一座“行走的超算中心”。据官方介绍，这也是人类历史上第一次，近百台全自主人形机器人在物理世界中完成群体协同。硬件方面，加速进化T2身高1.4米，全身最高拥有75个自由度，采用自研高爆发关节，最大扭矩可达140Nm，双臂最大静态负载达到10kg。其中，专业版标配英伟达Thor芯片，端侧算力达到2070 TFLOPS，同时搭载14核CPU，最高主频2.6GHz，并配备128GB 256bit LPDDR5X内存，端侧多模态推理延迟最低可达100ms。
