Unfortunately I'm not in Japan so I will present this work (in collaboration with @willrhobbs.bsky.social) remotely tonight/tomorrow morning in Japan. It is based on another interesting work about Weibo's surprisingly transparent community-driven digital jury system: osf.io/preprints/so...

很有意思！要是能在过评药品里发现as-if random的情况做自然实验就好了。如果有可靠的药品销量数据，也许可以一试？
一致性评价是确保仿制药有效、安全的关键监管措施。然而，若仿制药在通过一致性评价后，生产环节发生变化，是否依旧符合与参比试剂的一致性？
实际上，一款仿制药在通过一致性评价后，可对原材料供应商、生产工艺、生产厂址等多项生产环节进行变更，而无需重新进行一致性评价，多数情况只需在省级药监部门进行备案。
我分析了国家药监局公布的2019年至今的16万余条药物补充备案，发现通过一致性评价的仿制药、进入集采的药品中，广泛存在过评后生产环节的变更。
并且，进入集采的药品，相对于同成分但未进入集采的药品，进行了更多此类变更。
这些变更并非一定会影响药效、安全性，但仍需解决如何对此进行有效监管的问题。

我这段时间见的最可悲的事：反了一辈子文革，跑到海外看见什么都像文革都要反。最后真文革来了，立刻成了最坚定、最狂热的吹鼓手。
以种族性别斗争为纲，唯上是从，外行领导内行，小将抢班夺权，个人崇拜，政审，拍脑袋决策，和尚打伞无法无天，大字报，全部搞了一遍，他们识别不出这是文革

The new acting Undersecretary of State for Public Diplomacy — State’s top public diplomacy official:
1) not only denies the Uyghur genocide but appears to applaud it
2) says the US should sell out Taiwan to China for concessions in Antarctica (???)

This is a sad time for political scientists, and even much sadder for Chinese political scientists who wish to pursue a liberal democracy
China and Russia could not be happier right now.

Community Notes needs Journalism. Here's some scientific evidence for it @andyzhao.bsky.social and I provided last year in the Journal of Online Trust & Safety where we looked at the dynamics of Cofacts, the Taiwanese crowdsourced fact-checked community:

So, blatant racism in an AI ethics invited talk on #NeurIPS from an MIT professor. Guess she knows this is inappropriate, otherwise she wouldn’t even have a “Note”. Then she still chooses to leave the slide as it is and present it in this way.

1. The name Bluesky was originally a placeholder for the project started by Twitter to build an open social protocol.
Purely by coincidence, my mother gave me the name Lantian, which translates to "blue sky."

So...Bluesky was not named by Lantian, but still happened to have the same name as the CEO?
