They also needed an alternative to conventional X-rays. In a clinical linac, X-ray photons are produced by dumping high-energy electrons into a bremsstrahlung target, which is made of a material with a high atomic number, like tungsten or copper. The target slows the electrons, converting their kinetic energy into X-ray photons. It’s an inherently inefficient process that wastes most of the beam power as heat and makes it extremely difficult to reach the ultrahigh dose rates required for FLASH. High-energy electrons, by contrast, can be switched on and off within milliseconds. And because they have a charge and can be steered by magnets, electrons can be precisely guided to reach tumors deep within the body. (Researchers are also investigating protons and carbon ions; see the sidebar, “What’s the Best Particle for FLASH Therapy?”)
Anthropic 今天向外展示的「合作」姿态，听起来温和，甚至有点示好。市场也在一夜之间被安抚了，但没人真正回答那个根本问题：AI 冲击职场的终点，到底是人和 AI 一起干活，还是 AI 干活、人来担责，还是连这最后一道门槛也终将消失？。关于这个话题，新收录的资料提供了深入分析

習近平在週二（2月10日）的一場線上會議中表示，過去一年「很不尋常、很不平凡」，並指出軍隊「在反腐敗鬥爭中經受革命性鍛造」。，这一点在新收录的资料中也有详细论述
传统的AI仍然局限在ChatGPT、豆包这种以对话的形式输出内容，但是其只能输出文本、图片等等这种，涉及到具体的执行层面只是告诉你步骤，而非真正帮你去做。
