He thinks that the community was enclosed, living right next door to the cemetery, separated from the rest of society.
"We chose a threshold that requires a few searches within a short period of time, while still erring on the side of caution," Instagram's blog post explains. "While that means we may sometimes notify parents when there may not be real cause for concern, we feel — and experts agree — that this is the right starting point, and we’ll continue to monitor and listen to feedback to make sure we’re in the right place.",这一点在新收录的资料中也有详细论述

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?”),更多细节参见新收录的资料
