Omicron in Europe before South Africa reported first cases******

AFP

Travelers from South Africa are tested for the coronavirus on arrival in a specially designed test street at Schiphol airport, on November 30, 2021. Dutch health authorities said on November 30 that the new COVID-19 variant was already present in the Netherlands a week before a cluster of cases on two flights from South Africa. The Omicron cases were discovered on November 19 and 23 and authorities are checking whether they had links to southern Africa, and how far the new strain has spread.

The Omicron coronavirus variant was present in Europe before the first cases were reported in South Africa, new data from the Netherlands showed Tuesday, as Latin America reported its first two cases in Brazil.

In the week since the new virus strain was reported to the World Health Organization by South Africa, dozens of countries around the world have responded with travel restrictions – most targeting southern African nations.

But the World Health Organization warned Tuesday – as Canada expanded its restrictions to also include Egypt and Nigeria – that "blanket" travel bans risked doing more harm than good.

And the likely futility of broad travel restrictions was underscored as Dutch authorities reported that Omicron was present in the country before South Africa officially reported its first cases, on November 25.

The new variant – whose high number of mutations the WHO believes may make it more transmissible or resistant to vaccines – was found in two Dutch test samples from November 19 and 23, with one having no travel history.

With countries now on alert for the Omicron variant, a clearer picture is emerging by the day of where it has been circulating, and for how long.

So far, well over a dozen countries and territories have detected cases, including Australia, Britain, Canada, Israel, Italy and Portugal.

Among European countries, Belgium and Germany have both reported cases of the new strain prior to November 25, but both linked to foreign travel.

Latin America reported its first two cases Tuesday – in people who traveled from South Africa to Brazil – and a first case was confirmed in Japan, one day after it barred all foreign arrivals.

Vaccine-resistant?

While much is still unknown about the Omicron variant – it could take weeks to determine whether and to what extent it is vaccine-resistant – it has highlighted that the global fight against COVID-19 is far from over.

Asian, European and US markets all fell on Tuesday, while the benchmark US oil price tumbled more than five percent after the boss of vaccine manufacturer Moderna warned existing jabs might be less effective against the new variant.

"All the scientists I've talked to ... are like 'this is not going to be good'," Moderna boss Stephane Bancel told the Financial Times, warning against a "material drop" in the effectiveness of current jabs against Omicron.

Moderna, US drugmaker Pfizer and the backers of Russian vaccine Sputnik V are already working on an Omicron-specific vaccine.

On the treatment front, meanwhile, a panel of US health experts voted Tuesday to endorse Merck's COVID pill for high-risk adult patients, which is already authorised in Britain.

'Heavy burden'

In a briefing to WHO member states, the body's chief Tedros Adhanom Ghebreyesus said it was understandable for countries to seek to protect their citizens "against a variant we don't yet fully understand."

But he called for the global response to be "calm, coordinated and coherent", urging nations to "take rational, proportional risk-reduction measures."

The UN agency cautioned in a travel advisery that "blanket" travel bans risked placing a "heavy burden on lives and livelihoods" and could ultimately dissuade countries from sharing data about the evolving virus – as South Africa did in reporting the latest variant.

But it did advise that people not fully vaccinated and considered vulnerable to COVID-19, including over-60s, should put off travel to areas with community transmission of the virus – after correcting a previous statement that indicated all over-60s should defer travel.

Tougher measures

Omicron has emerged as much of the world was already bracing for a new winter wave of the pandemic – leaving even nations with high vaccination rates scrambling to stem infections and prevent health services from being overwhelmed.

Governments, particularly in western Europe, have already reintroduced mandatory mask-wearing, social-distancing measures, curfews or lockdowns – leaving businesses fearing another grim Christmas.

In Germany, incoming Chancellor Olaf Scholz said parliament would vote on making COVID vaccines compulsory by the end of the year – and a source from Scholz's party told AFP he had "signalled his sympathy" for such a rule.

Greece went ahead Tuesday in making vaccines compulsory for over-60s, while Norway will offer booster shots to all adults before Easter, as preferable to a lockdown.

Britain meanwhile set a target of delivering third jabs to all adults within two months, with Prime Minister Boris Johnson saying vaccination centers would be "popping up like Christmas trees."

China to face France, Nigeria, Mali in Women's Basketball World Cup qualifiers******

GENEVA, Nov. 23 (Xinhua) -- China will face France, Nigeria and Mali in Group B of the 2022 FIBA Women's Basketball World Cup qualifying tournaments next February, after the draw was made here on Tuesday.。

The four World Cup qualifiers will be played in Belgrade, Osaka and Washington D.C. from February 10 to 13, 2022, with Belgrade scheduled to host Group A and B matches.。

Group A features Australia, South Korea, Serbia and Brazil. Group C matches, to be staged in Osaka, feature Bosnia and Herzegovina, Japan, Canada and Belarus. In Group D, Russia, the United States, Puerto Rico and Belgium will take each other on in Washington D.C..。

The top three finishers from each qualifying tournament will secure their places in the 12-team flagship global women's basketball competition, which will take place in Sydney, Australia from September 22 to October 1, 2022.。

Host nation Australia and the Tokyo Olympic champions the United States have already earned automatic qualification, meaning that the two other best-placed teams will advance from those qualifying tournaments featuring Australia and the USA. Enditem。

炸场是真炸场 但也开了倒车 苹果新MacBook Pro值得买吗?******今日凌晨,苹果公布了全新MacBook Pro系列产品,基于M1 Pro和M1 Max芯片打造,采用mini-LED、最高120Hz的ProMotion动态刷新率屏幕,带来了巨大的性能飞跃与体验提升。全新MacBook Pro 14英寸起售价14999元,全新MacBook Pro 16英寸起售价18999元。

专业级M1 Pro和M1 Max芯片 性能强到没朋友

在9月的iPhone 13之后,10月19日凌晨苹果举行了今年的第二场秋季新品发布会,公布了搭载全新专业级芯片M1 Pro、M1 Max的全新MacBook Pro系列产品,以及支持空间音频的AirPods第三代和HomePod mini的三种全新配色,信息量还是很大的。

在宣传上一向克制的苹果在10月13日的发布会预告中甚至使用了一个流行的网络用语“来炸场”,看起来是自信满满。从今天凌晨发布会的效果来说,确实很炸,引起了整个科技圈与消费者的极大关注。尤其是全新的MacBook Pro,可以说是近五年以来的最大更新,在性能和屏幕方面,可以说是强到没朋友。

首先来说说新的M1系列芯片,虽然还是基于M1的架构进行拓展,还是5nm制程,但有了Pro和Max的后缀之后,CPU核心数、GPU核心数、统一内存、内存带宽、封装晶体管数均成倍增加,性能那是“快得吓人”和“快得太吓人”,毫不留情的把前代的M1拍到了沙滩上。

M1 Pro封装晶体管数达到337亿个,共10核心CPU,包括8个性能核心与2个高效核心;16核心GPU;最高可配置32GB统一内存,内存带宽达到200GB/s。与M1芯片相比,M1 Pro的CPU性能提升70%,GPU性能提升3倍。

至于M1 Max更是夸张,拥有10核心CPU,最高32核GPU,最高配备64GB统一内存,带宽达到400GB/s,接近M1的6倍。M1 Max封装的晶体管总数达到570亿(作为参考,英特尔第十一代酷睿i9-11900K的晶体管数量为60亿),比M1 Pro高出70%,比M1高出3.5倍,因此它也成为苹果迄今为止打造的最大面积的芯片。

连自家的产品都吊打了,与Intel相比,那更是一点也不客气。如果与配备4核英特尔酷睿i7处理器的上一代13英寸MacBook Pro相比,新的14英寸MacBook Pro性能最高可达其3.7倍;如果与配备8核心酷睿i9处理器的上一代MacBook Pro 16相比,新的16英寸MacBook Pro性能最高可达其2.1倍。

毕竟,去年WWDC2020的时候,苹果就明确表态,要用两年的时间将Mac产品线迁移到自研芯片,抛弃Intel,现在可谓是“虾仁猪心”,还没正式分手呢就开始当面补刀了。

巧的是,就在这次苹果发布会的前一天,英特尔现任CEO基辛格在采访中表示,英特尔要依靠更强的芯片赢回苹果这个客户…

至于GPU图形性能,M1 Pro与M1 Max更是成倍地增加,与搭载集成Iris Plus图形处理器的英特尔酷睿i7处理器的13英寸MacBook Pro相比,M1 Max的GPU性能足足提升了13倍。即使是与配备AMD Radeon Pro 5600M独显的16英寸MacBook Pro相比,在Final Cut Pro的8K渲染中也有着2.9倍的性能提升。

可怕的还在后面:同样的性能下,苹果M1 Max芯片的功耗要比搭载高性能移动GPU的PC低了100W,即使是在使用电池的时候,性能发挥依然火力全开。诚然,M1系列芯片基于ARM架构打造,在功耗方面与x86构架相比有着天生的优势,但M1 Max的能耗比也实在是夸张,与X86相比简直是降维打击。

并且,功耗的降低,还带来了电池续航方面的巨大提升。与上代产品相比,此次全新的MacBook Pro的电池续航时间几乎翻了一倍。

屏幕方面,此次新的MacBook Pro 14与16也带来了很大的升级,前者屏幕尺寸为 14.2 英寸,分辨率3204*1964,后者屏幕尺寸为16.2英寸,分辨率3456*2234。二者均采用mini-LED屏幕,最高120Hz的ProMotion动态刷新率、1000尼特持续亮度、峰值亮度1600尼特、对比度高达100万:1、10.7亿色显示、P3广色域、原彩显示技术,可以说,这是目前业界综合素质最优的笔记本屏幕了。

当然了,在综合素质提升明显的情况下,全新的MacBook Pro的价格也更Pro了。全新MacBook Pro 14英寸款,起售价14999元,全新MacBook Pro 16英寸起售价18999元。

特别的是,这次库克可能是与老黄有过交流,刀法愈加精进,提供丰富的选择,贴心的提供了8核心和10核心CPU,14、16、24、32等不同核心数量的GPU选项,如果直接拉满配置,价格将来到45999元。

综合来看,搭载M1 Pro和M1 Max芯片的全新MacBook Pro的确可以称得上是炸场,最起码在专业生产力型的笔记本电脑品类中,综合体验可以说没有敌手。谈到苹果产品,一向是以整个苹果生态为前提,产品的体验提升,不单纯是硬件的优势,iPhone是这样,这次的MacBook Pro也是这样,M1系列芯片与macOS的生态优势相加,才是全新MacBook Pro的价值所在。

最新的macOS Monterey操作系统已针对M1 Pro和M1 Max芯片进行了深度优化,能够充分利用内置的ISP和AI单元,加强摄像头画质,提供更优体验。另外,除了苹果自家的软件之外,苹果已经与大量第三方专业软件供应商达成合作,针对M1 Pro和M1 Max芯片完成适配与优化工作,包括Adobe系列软件、Blackmagic Design DaVinci Resolve Studio、Maxon Cinema 4D、NASA TetrUSS等,这些软件已经可以利用新款MacBook Pro的性能,实现处理速度的加倍提升。

因此,新的MacBook Pro将成为照片编辑、平面设计、三维渲染、音频制作、视频剪辑、软件开发、STEM教育等专业人士的高效工作站。

县级融媒体中心亮相中国网络媒体论坛******

  11月24日至25日,2021我国互联网媒体社区论坛在西安举办。期内,来源于全国各地好几个区域的县级融媒体中心集中化展现,在连通联接老百姓的“最后一公里”上各显其招,展览了多种多样“网络媒体”的创新思维方法。

\

  新闻记者认识到,第一届我国互联网媒体社区论坛新技术应用新运用业态创新展览会做为一项重要创新成果,是国内初次以媒体传播为主题风格的大中型线下推广展览会。汇萃了中央新闻企业、地区新闻报道企业、著名互联网公司、县级融媒体中心及港粤澳大湾区区域内的互联网媒体、互联网公司等40多家企业出展,集中化呈现互联网媒体行业的新技术应用、新运用、业态创新,是目前为止中国经营规模较大、设计方案全新、遮盖最广、交互性最強的互联网媒体展览会。中新网筹办了在其中的“县级融媒体中心展示厅”,集中化展现了福建尤溪县、广东省清新区、陕西省陈仓区、浙江长兴县、甘肃玉门市、湖北赤壁市、江西分宜县、江苏省江阴市等县级融媒体中心发展趋势状况。

  在展现区域内,小视频非遗文化新项目课堂教学、当场联线“农村新闻官”叙述家乡变化、新闻报道商品展示等主题活动内容丰富。出展的福建尤溪县网络媒体中心产生了形式多样新奇的新闻报道商品。该中心负责人彭丹称,她们十分看重內容艺术创作,还使用了各种新的方式方法让新闻事业更具有诱惑力。

  彭丹举例说明说,例如把AR技术性应用到《尤溪周刊》《小康时代》《振兴之路》电视节目中,许多没法复原当场的电视节目艺术创意就可以用主播的跑位来调节AR情景,那样可以有效的填补实景拍摄中真正自然环境的缺少,与此同时在视觉效果上还可以更为形象化地阐释综艺节目內容,对消息的传递开展填补,这也是尤溪县网络媒体中心维持“内容为主”竞争优势的重要。

  在发展趋势网络媒体中心的与此同时,出展的广东省清新区网络媒体中心还推行了农村新闻官的方式。该中心办公室副主任王闻宇详细介绍,农村新闻官精准定位为底层宣传策划做事、现行政策宣传教育员、县级融媒体中心新闻记者、乡村网红。

  中国新闻网小编在该中心展示区内见到,农村新闻官们根据当场直播带货的方式,推荐家乡美景的农业产品。王闻宇称,清新区的农村新闻官根据结对子、搭服务平台、建管理体系、强管理方法、保高效,连通正确引导人民群众、为民服务的“最后一公里”。

  在陕西省陈仓区网络媒体中心展示区内,造型设计独特、色彩鲜艳的京剧脸谱吸引住了新闻记者的眼光。出展的陕西工艺美术品高手、宝鸡市社火脸谱手艺传承人薛亚兵告知中国新闻网新闻记者,这类京剧脸谱称之为社火脸谱,因遭受周朝文化艺术危害,多以《封神榜》为主题开展艺术创作。

  薛亚兵觉得,宝鸡市社火脸谱做为非遗文化新项目,用小视频的方式拍攝出来并公布网上,用年轻一代喜爱的方法散播历史悠久手艺,拉进与观众们的间距是有效的试着。宝鸡市陈仓区广播电台台长齐小斌认可薛亚兵的观点。

  齐小斌详细介绍,陕西省陈仓区网络媒体中心依照“融为一体,合而为一”的方式,充足融合广播节目、电视机、网址、手机上APP等服务平台資源,积极主动扩展“新闻报道 政务服务”“新闻报道 服务项目”等行业,根据新的方法、新的方式,在内容为主的条件下,融进受众群体、为民服务。
