Preview: Three debutants in new dugouts as Premier League returns to action******

LONDON, Nov. 19 (Xinhua) -- Three coaches will make their debuts for their new clubs as the Premier League returns to action in what promises to be another fascinating weekend.。

Steven Gerrard's debut after leaving the Glasgow Rangers for Aston Villa will probably attract most of the attention as he looks to end the run of five defeats which cost Dean Smith his job.。

Villa entertain Brighton and much of the attention will be to see if Gerrard can bring the best out of players such as Leon Bailey and Emi Buendia, but he also needs others such as John McGinn and Tyrone Mings to be at their best against a rival that is likely to have most of the ball.。

Dean Smith was out of work for eight days before he was confirmed as the replacement for Daniel Farke at bottom of the table Norwich City and Smith makes his Norwich debut at home to Southampton.。

The irony of the fixture calendar means that Smith's first game as Norwich City coach is against the same team that defeated Aston Villa in his last game in charge there and who have won their last two games 1-0.。

Eddie Howe is the final debutant of the weekend, as Newcastle United continue to look for their first win of the season at home to a Brentford side that is suddenly in trouble after four consecutive defeats.。

Brentford travel north with several players out injured and it looks like the ideal moment for Howe to get off to a flying start in front of an expectant St James' Park.。

League leaders Chelsea are first into action this weekend with a visit to play Leicester City, who will be without the influential Youri Tielemans.。

Manchester United coach Ole Gunnar Solskjaer needs a relatively calm afternoon when his side visits Watford. Home defeats to Liverpool and Manchester City have left Solskjaer's men chastened, but they should have too much firepower for a rival that has lost three out of four games since Claudio Ranieri replaced Xisco Munoz at the helm.。

Liverpool against Arsenal also promises to be a fascinating match as Mikel Arteta's side measures a recovery that has seen them win four and draw two of their last six matches at Anfield.。

Much of Arsenal's recent good form is down to their defensive solidity with Gabriel and Ben White in defense, but they will have to be at their best to keep Mohamed Salah and company at bay.。

West Ham flew striker Michail Antonio back in a private jet from Jamaica to ensure he would be fully fit for Saturday's visit to play Wolves and David Moyes' side can be expected to cause Wolves a lot of problems from set pieces as they did against Liverpool a fortnight ago.。

Burnley seem to slowly be recovering from their dreadful start to the season with just one defeat in six games and Sean Dyche's men will be hoping to climb out of the bottom three with a win over Crystal Palace, who will face a physical battle at Turf Moor.。

Sunday has two games with Manchester City entertaining Everton, who are without a win in their last five league matches, before the weekend's last match will put Harry Kane in the spotlight for Antonio Conte's home debut as Tottenham coach.。

Kane netted seven goals in 108 minutes for England during the international break, but so far, he has only one league goal this season. The visit of Leeds United looks like the moment for Kane to carry that form over for his club and put a difficult early season behind him. Enditem。

China's Gao wins men's 500m race at ISU Speed Skating World Cup in Poland******

WARSAW, Nov. 12 (Xinhua) -- China's Gao Tingyu, a bronze medalist at the PyeongChang Winter Olympics, won the men's 500m with a new track record of 34.265 seconds at the ISU Speed Skating World Cup in Tomaszow Mazowiecki, Poland on Friday.。

It is the first time for Gao, 24, to claim a World Cup title.。

Nearly three hundred skaters from 35 countries and regions take part in the competition that inaugurated the World Cup cycle, which is also Olympic qualifications.。

Gao showed a masterclass in the first race of the Division A at 500 meters. The silver and bronze went to Japanese Tatsuya Shinhama and Laurent Dubreuil from Canada respectively.。

In the 500m Division B race Yang Tao took the third place, behind home skaters Piotr Michalski and Damian Zurek. The 24-year-old crossed the line in 35.241. His compatriot Liu An was fifth with 35.351.。

Zhang Lina earned 16 points in the general classification after she took fifth position in the women's 500m Division B. The race was won by the Pole Andzelika Wojcik, Kimi Goetz from the United States was second. In the 500m Women Division A Jin Jingzhu achieved a sixth result, while her compatriot Tian Ruining was seventh.。

Two-time world champion Irene Schouten turned out to be the best at the women's 5,000m. The Dutch set a new track record with 4:4.009. Canadian Isabelle Weidermann and Italian Francesca Lollobrigida also stood on the podium.。

Sweden's Nils van der Poel took gold in the men's 5,000m Division A, followed by Ten Jan-Bloemen and Patrick Roest. Enditem。

英特尔新一代酷睿核心规格型号有所不同,对散热或有影响******

  在最近intel宣布推送了集团旗下的第12代酷睿处理器,而来源于微星面层面的信息,桌面上AlderLake有两个不一样的结构:一个有高达8个P核和8个E核的集成ic(一共有24个进程),另一个为较多有6个P核,沒有E核(12个进程)。从而这两个版本有关键面积上的不一样,二者中面积比较大的面积为215平方电线,而小的表面积为163mm。

  表面积不一样的难题还产生了集成ic发网络热点不一样的难题,在一个难题将有可能造成排热层面的特性差别,针对排热的兼容模式也许有更进一步的规定。


84%感染者出现后遗症 最新研究:新冠病毒还能杀死脑细胞******

  随着新冠病毒继续在全球各国肆虐,感染新冠病毒后的后遗症,已经引起了科学家们的关注。所谓新冠后遗症,即在首次感染新冠病毒后可能出现的一系列新的、复发或持续的健康问题。

  其中,根据美国疾控中心(CDC)的官方信息,感染新冠病毒的长期影响之一是出现“脑雾”,即思维和注意力难以集中。事实上,新冠病毒对大脑的影响并不仅仅是出现脑雾。此前的一项研究发现,高达84%的新冠感染者出现了神经症状、味觉或嗅觉丧失、癫痫发作、中风、意识丧失及意识混乱等“新冠后遗症”。但令科学家们迟迟未能找到这一问题背后的答案,这些新冠后遗症究竟为何出现?

  据外媒10月24日报道,一项发表于《自然神经科学》上的最新研究或许解开了这一谜题,因为新冠病毒除了攻击肺部外,还能杀死脑细胞。

▲高达84%的新冠感染者出现了“新冠后遗症”【后遗症表现】

  近四分之一感染者康复后

  出现认知障碍,大脑无法正常工作

  《美国医学会杂志网络公开(JAMA NetworkOpen)》10月22日发布的一项新研究表明,新冠感染者在感染的几个月后出现了记忆问题,甚至“无法思考”。研究人员对纽约西奈山医疗系统740名新冠肺炎住院患者进行了研究发现,近四分之一的人在感染的几个月后大脑无法保留信息和集中注意力。

  “在这项研究中,我们发现患者在感染新冠病毒几个月后出现认知障碍的频率相对较高。在住院患者中,执行功能、处理速度、分类流畅性、记忆编码和回忆方面的障碍最为明显。”纽约西奈山伊坎医学院的杰奎琳·贝克尔解释道。

  该研究称,曾因新冠肺炎住院的人最有可能出现认知障碍迹象,但在医院急诊科接受治疗的一些感染者也出现了脑功能下降。这些患者通常在感染新冠病毒约7、8个月后,表现出认知障碍的迹象,包括记忆、回忆和存储新记忆、做出判断及计划当面的问题。

  精神病学教授海伦·拉夫雷茨基博士表示,有些病人“大脑甚至完全无法正常工作”,无法思考、记忆受损;当他们开车出行的时候,会感到困惑,不知道自己究竟是如何到达目的地的。

  ▲新冠病毒会破坏位于大脑周围的内皮细胞,导致血液无法流动。【最新研究】

  新冠病毒杀死内皮细胞

  导致“幽灵血管”出现

  尽管在新冠疫情后不久,科学家们便逐渐注意到了新冠感染者在康复后出现了各种大脑及神经问题,但始终未能找到症结。而现在,一项发表于《自然神经科学》上的最新研究表明可能揭开了这一谜题。

  据报道,这项由德国、法国和西班牙科学家联合进行的研究表明,新冠病毒除了攻击肺部外,还能杀死一种被称为内皮细胞的脑细胞。内皮细胞位于大脑周围,负责保护小脑,促进血液流动。研究人员指出,内皮细胞受损可能会导致大脑血管损伤,损害认知功能。他们表示,这一发现或许可以解释,为何高达84%的新冠感染者都出现了神经症状、味觉或嗅觉丧失、癫痫发作、中风、意识丧失及意识混乱等“新冠后遗症”。

  研究人员通过扫描新冠肺炎死者尸体的大脑发现了一种极为细小的“幽灵血管”,这是一种让血液无法流动的死细胞,也是认知障碍的标志,并可能产生众多风险,比如微中风等等。

  专家解释

  这一问题或许是可逆的

  但长期影响仍然无法确定

  这一令人震惊的发现,不可避免地引发了一个问题:感染新冠病毒的人是否将不可避免地长期受到脑部问题的困扰?

  该研究合著者、法国国家健康与医学研究院(INSERM)的文森特·布雷奥表示,这种大脑的损伤可能是可逆的。他解释道:“我们在仓鼠身上看到了这种现象显然是可逆的,所以它在人类身上也或许是可逆的。”

  其次,研究表明,这种情况可能发生在病情严重的感染者身上。但对于症状较轻微的感染者来说,暂时还没有确定的结论。“为了找到答案,我们必须连续一周每10分钟采集一次血液样本,以检测血液中是否存在病毒。不幸的是,这种方法并不可行。”他表示。

  报道称,从长远来看,感染新冠病毒对大脑的损伤是否持续存在,并影响受损大脑的老化状态等众多问题仍未得到确切解答,科学家们还需要时间和进一步的研究才能找到答案。
