原标题：英国给拜登"开后门"► 文观察者网熊超然已故英国女王伊丽莎白二世的葬礼将于当地时间9月19日举行，预计英国将在近期迎来大量外国贵宾的到来。然而，此前“不能率团”和“让外国元首乘商业飞机及坐集体大巴”等严格要求，也被许多外交官吐槽。有匿名外国大使就对媒体表示：“你能想象拜登坐在大巴车上的样子吗？”当地时间9月12日，英国《泰晤士报》进一步披露称，美国总统拜登将有权乘坐其“野兽”防弹专车前往威斯敏斯特教堂参加女王葬礼，法国总统马克龙等极少部分外国政要也可能获此许可，而其他一些国家的领导人则将必须乘坐英方指定的公共大巴车参加活动。《泰晤士报》报道截图据报道，英国女王的葬礼确定于当地时间9月19日11时在伦敦威斯敏斯特大教堂举行，这也是伊丽莎白二世举办登基仪式和婚礼的地点。这是英国自1965年前首相丘吉尔的葬礼以来，迎来的又一场堪称史无前例的后勤安排和外交活动，需要为最大规模的外国政要来访做好准备。 The same technology that may power the next generation of mobile networks has been shown to increase the growth of brain cells in mice, according to a new study from Xian Jiaotong University in Beijing.,Radio waves in the terahertz frequency can transmit data at speeds up to 1 terabit (or 125 gigabytes) per second, it is a prime candidate for the next generation of mobile cell phone networks if it can be proven safe. By contrast, current 5G networks use millimeter waves that top out at 20 gigabits (2.5 gigabytes) per second.,But there may be another use for terahertz radio waves: treatment of neurological disorders like Alzheimer’s disease, autism, and Parkinson’s disease.,Science & Tech'Vicious Cycle' Between Alzheimer's Dementia and Daytime Napping Found by Scientists17 March, 19:05 GMT,The researchers exposed mice neurons in a petri dish to 100-microwatt pulse radiation, ranging from 0.3 terahertz to 3 terahertz. The result was that the exposed neurons grew at a rate of 150% compared to the control group. The length of connections also doubled in three days. Despite the accelerated growth, the brain cells appeared healthy.,The accelerated brain growth was not permanent; it slowed two days after exposure.,However, a 2009 study by the Russian Academy of Sciences showed that prolonged exposure to strong terahertz radiation had an adverse effect, increasing the temperature of brain cells, disturbing their development and causing dehydration of the cells which reduces their size and causes other damage.,But Li Xiaoli, the lead scientist of the new Beijing study, thinks that the negative effects of terahertz radiation could be avoided by limiting the strength and duration of exposure.,“The safety of terahertz radiation protocol is a top concern,” Li said. And while the health concerns of terahertz radiation remain, it could, Li believes, be used to treat neurological disorders.,“Abnormal neuron development and the resulting abnormal neural network structure can lead to the occurrence of various psychiatric and neurological diseases, such as Alzheimer’s disease, autism and Parkinson’s disease,” the study’s authors said.,The authors believe that a lower dose of terahertz radiation could increase the production and the activity of certain proteins responsible for brain cell growth, namely GluA1, GluN1, and SY-38. The researchers theorize that is because they contain hydrogen bonds that constantly vibrate at a frequency that falls in the terahertz range. The radio waves combine with the proteins and cause them to resonate in a “non-linear manner,” according to Li, which could “affect the shape of the proteins, and therefore the structure and function of neurons.”However, because proteins vary significantly from each other, only certain proteins are affected by the terahertz radiation at low frequencies. Li says more investigation is needed to learn how proteins react to different exposure intensities.,The study backs up another done at the Institute of Brain Science at Xian Jiaotong University that was published in June. That study found that terahertz exposure could make young mice more intelligent. There, scientists exposed mice to 90-milliwatt terahertz radiation for 20 minutes a day for three weeks. They observed that the exposed mice had more brain cells and were quicker at escaping mazes. However, for reasons that remain unclear, the same effect was not observed in older mice.。预计届时将有100多位各国国王、王后和国家元首出席英女王葬礼，然而，大量贵宾的入境也给英国政府在后勤和外交层面带来麻烦，官员们也试图在满足外国贵宾需求和活动顺利举行之间取得平衡。按照安排计划，每个和英国有外交关系的国家所能派出参加葬礼的代表名额极为有限，而出于担心威斯敏斯特教堂附近出现交通堵塞，大部分贵宾都被要求在伦敦西部的一个未公开地点集中搭乘公共大巴车，“拼车”前往活动地点。不过，这其中也明显有例外情况。《泰晤士报》援引英国白厅（WhiteHall）消息人士报道称，出于安全考虑，已确认出席葬礼的美国总统拜登将被允许乘坐其被称为“野兽”的凯迪拉克防弹专车，前往威斯敏斯特教堂。除此之外，同样是出于安全考虑，包括法国总统马克龙、日本德仁天皇和以色列总统赫尔佐格也可能被允许乘坐各自的专车。一名英国政府消息人士还对媒体表示，要求七国集团（G7）领导人“挤大巴”显然是不合适的，但他又补充称，英方也正在要求各国政要尽可能地“灵活安排”。资料图：当地时间2021年6月13日，美国总统拜登与英国女王伊丽莎白二世在英国温莎城堡会晤。图自澎湃影像报道介绍称，预计将出席英女王葬礼的外国君主包括了比利时国王和王后、瑞典国王和王后、荷兰国王和王后、西班牙国王和王后。此外，已于2014年退位的西班牙前国王胡安·卡洛斯一世也将同其妻子索菲亚王后一起出席葬礼。除拜登和马克龙之外，已确认出席的其他外国领导人则包括加拿大总理特鲁多、澳大利亚总理阿尔巴内塞、新西兰总理阿德恩、南非总统拉马福萨和德国总统施泰因迈尔等。而因为英方表示“空间有限”，诸如特朗普等外国前领导人都不会受邀出席。综合美国“政客新闻网”欧洲版（politico.eu）、英国《卫报》、《独立报》等多家外媒9月11日的报道，它们获得了一份据称是英国外交部发给各国使馆的关于女王葬礼仪式的指导文件，其中包含了外国访客入境后的各项安排。《天空新闻》澳大利亚版形容这样的安排“相当严格”，甚至还有一些“令人惊讶的禁令” ：为了避免造成伦敦机场和交通拥挤，受邀出席的外国元首不仅被要求乘坐商业飞机抵达伦敦，参加葬礼时还不得使用元首专车，而是到集合点乘坐大巴车统一前往，就连葬礼场地也只允许领导人及其伴侣或配偶至多2人进入。
