达芬奇的恶魔CDC: ‘Eris’ Responsible for 22% of New COVID-19 Infections_我的网站
A | The coronavirus strain nicknamed “eris” was responsible for more than 1 in 5 new infections in recent weeks, according to updated data from the Centers for Disease Control and Prevention. EG.5, or “eris,” is the top strain circulating in the U.S., causing nearly 22% of cases over the past two weeks, according to CDC data. The strain has been increasing in recent weeks as XBB.1.5 declines. It’s also the most prevalent strain globally, according to the World Health Organization. The U.N. health agency designated EG.5 a “variant of interest,” warning that it could cause a rise in cases globally. EG.5 appears more transmissible and better able to evade immunity provided by vaccines and previous infection, according to WHO. But it hasn’t been associated with more severe disease. Its rise in the U.S. comes as COVID-19 hospitalizations have increased for six straight weeks. The CDC’s variant tracker does not yet include BA.2.86, a highly mutated strain that has been found in low levels in the U.S. According to the CDC, BA.2.86 was responsible for less than 1% of infections over the past two weeks in the U.S. The CDC updated its risk assessment for BA.2.86 this week. It said that based on current data, “existing tests used to detect and medications used to treat COVID-19 continue to be effective with this variant.” Additionally, researchers believe the new COVID-19 booster shots set to roll out this month will likely protect against severe disease and hospitalization from the strain.
B | 不过，越来越多的汽车制造商开始将纽博格林视为自动驾驶技术的试验场。小米在今年夏天率先展开尝试，一辆搭载自动驾驶技术的小米 YU7 GT 用 10 分 29.483 秒完成了一圈，达成全球首个纽北自动驾驶圈速纪录。这个成绩比人工驾驶的同款车型慢了 3 分多钟，但对于一辆自动驾驶汽车来说，这样的表现已经相当不错。如今，梅赛德斯-AMG 似乎也准备加入这一行列。近日，谍照摄影师拍到一辆 GT 63 原型车正在进行测试。乍看之下，这辆车与普通车型并没有太大区别，但车顶上安装了三个传感器。此外还可以看到，车内“驾驶员”特意将双手放在方向盘之外。据谍照摄影师透露，这辆原型车首先以非常缓慢的速度沿着赛道最右侧行驶，用于完成赛道的圈速测试和地图采集。整个过程大约耗时 25 分钟，随后车辆又切换到赛道最左侧，重复进行圈速测试和地图采集。
C | 在确定赛道两侧边缘的位置后，这辆原型车终于做好了完全脱手驾驶的准备。
D | 第一次自动驾驶正式跑圈时，车辆完成了一个“非常缓慢且谨慎的圈”。
E | 据报道，车辆整体驾驶风格十分保守，加速受到严格控制，并且会提前进行制动。这一圈耗时不到 20 分钟，车内“驾驶员”全程只是为了在出现问题时进行干预。成功完成测试后，车辆返回维修区，让工程师分析采集到的数据，并进一步调整车辆的相关设置。随后，这辆原型车再次驶上赛道进行第二圈测试，完成时间比第一圈“快了几分钟”。不过，据报道，这一成绩“距离小米创下的纪录还差得很远”。据了解，梅赛德斯-AMG 似乎在完成第二次测试后暂时结束了此次测试。不过毫无疑问，该公司将仔细分析这次测试获得的数据，并从中总结经验。
F | 预计这辆原型车未来会再次出现在纽博格林赛道，并尝试创造属于梅赛德斯-AMG 自己的自动驾驶圈速纪录。
