The objective is a tall order. The quantum-resistant cryptographic data needed to transparently publish TLS certificates is roughly 40 times bigger than the classical cryptographic material used today. Today’s X.509 certificates are about 64 bytes in size, and comprise six elliptic curve signatures and two EC public keys. This material can be cracked through the quantum-enabled Shor’s algorithm. Certificates containing the equivalent quantum-resistant cryptographic material are roughly 2.5 kilobytes. All this data must be transmitted when a browser connects to a site.
Imagine a vast shopping mall parking lot with thousands of individual parking spots and internal lanes (representing road segments within a cluster). No matter how complex it is inside, there are usually only a few key exits to the main roads. Our goal was to identify these natural "exits" for each map cluster. For instance, the complex road network around Amsterdam Airport Schiphol (see on OpenStreetMap) has many internal roads but limited primary access points.。51吃瓜对此有专业解读
一项针对超过8000块电动汽车电池的研究得出结论：大多数电池的使用寿命已经超过了它们所搭载的车辆本身。这一发现极大地缓解了长期以来围绕电池耐用性的普遍担忧。，详情可参考搜狗输入法下载
The astronaut who experienced a medical issue in space last month has identified himself as the sick member of his crew prompting an evacuation from the International Space Station.
这种“重资产”的服务投入，看似是成本支出，实际也为平台赋能产业提供了信用背书：因为背后有了平台兜底，中小商户才敢于接待复杂的国际订单；因为知道遇到困难能获得有效救援，游客也才敢于探索非标的小众目的地。
