微软发表 MatterGen: 利用 Diffusion Model 实现材料设计

“MatterGen 是一种在材料的三维几何上运行的扩散模型，在 MP 和 Alex 数据库中训练了 60 万种稳定材料。图 3 中， MatterGen 可以持续生成更多新颖候选材料。相比之下，基线早就耗尽候选而停滞。

与 ImgGen 类似，扩散模型通过调整随机结构的位置、元素和周期性晶格来生成建议的结构。并且可以微调以在不同设计要求下生成材料，如特定化学、晶体对称性或偏好供应链安全元素。

通过与中科院 SIAT 团队合作合成了一种新型材料 TaCr2O6，其结构由 MatterGen 在设定弹性模量为 200 GPa 下生成，实验测得为 169 GPa，相对误差低于 20%，从实验角度来看非常接近。”

Telegram hopes to raise $1bn with a convertible bond private placement

The super secure UAE-based Telegram messenger service, developed by Russian-born software icon Pavel Durov, is looking to raise $1bn through a bond placement to a limited number of investors from Russia, Europe, Asia and the Middle East, the Kommersant daily reported citing unnamed sources on February 18, 2021.The issue reportedly comprises exchange bonds that could be converted into equity in the messaging service that is currently 100% owned by Durov and his brother Nikolai.Kommersant reports that the price of the conversion would be at a 10% discount to a potential IPO should it happen within five years.The minimum bond placement is said to be set at $50mn, but could be lowered to $10mn. Five-year bonds could carry an annual coupon of 7-8%.

Telegram and Signal Havens for Right-Wing Extremists

Since the violent storming of Capitol Hill and subsequent ban of former U.S. President Donald Trump from Facebook and Twitter, the removal of Parler from Amazon’s servers, and the de-platforming of incendiary right-wing content, messaging services Telegram and Signal have seen a deluge of new users. In January alone, Telegram reported 90 million new accounts. Its founder, Pavel Durov, described this as “the largest digital migration in human history.” Signal reportedly doubled its user base to 40 million people and became the most downloaded app in 70 countries. The two services rely on encryption to protect the privacy of user communication, which has made them popular with protesters seeking to conceal their identities against repressive governments in places like Belarus, Hong Kong, and Iran. But the same encryption technology has also made them a favored communication tool for criminals and terrorist groups, including al Qaeda and the Islamic State.
