一 |     Washington, Oct 18 (UNI) Scientists at Boston University has developed a new Covid-19 strain which resulted in an 80 per cent kill rate in mice.

The variant, a combination of Omicron and the original virus in Wuhan, killed 80 per cent of the mice infected with it, the university said. When mice were only exposed to Omicron, they experienced mild symptoms, the New York Post said.

A team of scientists from Florida and Boston at the school’s National Emerging Infectious Diseases Laboratories conducted the research.

They extracted the spike protein from Omicron and attached it with the strain first detected at the onset of the pandemic that began in Wuhan, China. They then documented how the mice reacted to the hybrid strain, according to the New York Post report.

“In…mice, while Omicron causes mild, non-fatal infection, the Omicron S-carrying virus inflicts severe disease with a mortality rate of 80 percent,” they wrote in a research paper.

The new strain has five times more infectious virus particles than the Omicron variant, researchers said.

UNI PRT。根据Gartner的数据，全球PC出货量在2018年第四季度下降了4.3%。Gartner表示，第四季度PC出货总量达到6860万台，较2017年第四季度下降4.3%。Gartner资深分析师Mikako Kitawgawa认为，CPU短缺是导致PC出货放缓的原因，这表明CPU短缺导致供应链问题，正如PC市场的需求开始显示出积极的一面。PC出货量在第二和第三季度增长了两个季度后，第四季度有所下降。联想在第四季度是世界之王，其24.2%的市场份额为1663万台。

二 | 惠普的出货量下降了4.4%，位居第二，戴尔的出货量上升了1.4%，位居第三。华硕和宏基受到的打击最大，出货量分别下降10.7%和18.3%。第四大苹果公司本季度全球出货量为490万台，低于2017年第四季度的510万台。

三 | 然而，苹果的市场份额从7.1%微涨至7.2%。

四 | Gartner估计，苹果在美国市场的出货量为176万台，同比下降2.1%。有趣的是，尽管11月推出了新款MacBook Air和MacMini，但苹果Mac的出货量却下降了。上周，苹果在给投资者的一封信中下调了其第一季度的预测，理由是iPhone在大中华区的销量低于预期。值得注意的是，苹果公司已经停止宣布苹果公司上个季度宣布的Mac销售，称销售不再是其业务的最佳指标。

五 | 总体而言，Gartner估计2018年PC出货量为2.594亿台，较2017年下降1.3%。
