Long recovery after "unusual" tornado outbreak strikes US states******

Debris are piled after a tornado tore through rural Kentucky.

Rescue and recovery efforts are underway after dozens of tornadoes swept through parts of the US Midwest and South late Friday and early Saturday, causing severe casualties and damage.

"There is no lens big enough to show you the extent of the damage" in Kentucky, Governor Andy Beshear told reporters on Sunday, as several other states have also reported storm-related damage and deaths.

The tornado outbreak of that magnitude was unusual during this time of the year and the road to recover could be long in some affected regions, experts and officials have said.

Houses, structures, and Vehicles are seen with damage after a tornado tore through rural Kentucky.

Deadly tornadoes

Eighteen counties in Kentucky have reported damage from an extremely devastating tornado, which carved out a long path of about 227 miles (roughly 365 kilometers) of terrain – almost all of that in the "Bluegrass State," said Beshear.

The National Weather Service on Sunday classified the tornado as an EF-3 and estimated its maximum width to be about three-quarters of a mile (roughly 1.2 kilometers) wide.

Beshear, after previously estimating that the state's death toll could exceed 100, said on Sunday afternoon that it might be as low as 50. "We are praying that maybe original estimates of those we have lost were wrong," he reportedly said. "If so, it's going to be pretty wonderful."

The comments came after a spokesperson for a candle factory in the western Kentucky town of Mayfield, which had been flattened by the violent twister, said that eight of the 110 workers on the overnight shift Friday had been confirmed dead and another eight are still missing, while 94 others have been accounted for.

The tornado also uprooted trees, downed power lines, and damaged or destroyed houses and vehicles in Mayfield, where thousands of people have been left homeless.

Bulldozers began removing debris in some neighborhoods on Sunday. Residents of Wickliffe, a county neighboring Mayfield which narrowly escaped storm's impact, told Xinhua that they had been encouraged to help shelter the displaced.

Rescue efforts are being conducted by local response teams, Kentucky emergency officials said. The state has also deployed the National Guard to conduct searches and take generators to help power shelters and hospitals.

"We want to focus today and the next day on life-saving. We really want to make sure that we find anybody who still might be trapped in the rubble," Deanne Criswell, administrator of the Federal Emergency Management Agency (FEMA), said on Sunday.

Tragic situation

Tornadoes also ripped through Illinois, Tennessee, Arkansas, Missouri and Mississippi, and brought about deadly and tragic destruction in several of the states.

At least six people died in Illinois, where a distribution center owned by e-commerce giant Amazon in Edwardsville was struck and collapsed.

"The news from Edwardsville is tragic," Amazon founder Jeff Bezos tweeted on Saturday. "We're heartbroken over the loss of our teammates there, and our thoughts and prayers are with their families and loved ones."

Besides, four deaths were confirmed in Tennessee; two people were killed in Arkansas; and one death was reported in Missouri.

Tennessee Governor Bill Lee on Saturday surveyed storm damage in the western part of the state, including Dresden, where multiple downtown buildings were torn apart. "This is about the saddest thing I've ever seen," Lee told reporters. "The whole town, the whole town."

US President Joe Biden said on Saturday that he's "monitoring the situation very closely since early this morning" and called the disaster likely "one of the largest tornado outbreaks in our history."

The White House said on Sunday that Biden had declared that a major disaster exists in Kentucky and ordered federal aid to supplement the state and local recovery efforts "in the areas affected by severe storms, straight-line winds, flooding, and tornadoes."

"It's going to be a long recovery," said Criswell, adding that the FEMA is working with communities in making efforts to "help reduce the impacts that we're seeing from these severe weather events."

UNUSUAL MAGNITUDE

Unusual magnitude

Tornadoes can form at any time of year, but most occur in the spring and summer months, according to meteorologists.

Defined as vertical funnels of rapidly spinning air, these violent twisters are born in thunderstorms and are often accompanied by hail. Their winds may top 250 miles (roughly 402 km) an hour and can clear a pathway a mile wide and 50 miles (roughly 80 km) long.

Tornadoes occur around the world, but the United States is a major hotspot with about a thousand tornadoes every year.

Victor Gensini, an extreme weather researcher at Northern Illinois University, pointed out, however, that the powerful tornadoes churning through the US states were unusual coming in December, when colder weather normally limits the storms.

Criswell said something similar on Sunday.

"We do see tornadoes in December, that part is not unusual, but at this magnitude I don't think we've ever seen one this late in the year," the FEMA chief said. "But it's also historic. Even this, the severity and the amount of time this tornado, or these tornadoes, spent on the ground is unprecedented."

She also warned such extreme weather events could be a "new normal," pointing to the effects of climate change.

Biden said "the intensity of the weather across the board has some impact as a consequence of the warming of the planet and the climate change."

"The specific impact on these specific storms, I can't say at this point," the president added. "But the fact is that we all know everything is more intense when the climate is warming – everything. And, obviously, it has some impact here, but I can't give you a quantitative read on that."

“四舍五入!”未来钥匙DDR5正式发布******

  北京时间10月28日凌晨,intel十二代酷睿正式解禁。与前几代酷睿不同,新款CPU终于不再是打磨已久的14nm,而是采用了全新的10nm制程。除了全新制程的CPU以外,intel还为用户带来了PCIe 5.0、Z690主板、大小核心等新型技术。其中正式解禁的DDR5内存也是用户重点关注对象,与12代酷睿一时瑜亮。

  回顾下整个DDR5发展之路,会DDR5的研发速度超乎想象,从17年开始起步,到现在仅用了短短不到5年便正式发布,快到让用户几乎未能感知它的实际意义。许多用户都会有疑问,DDR5究竟与DDR4有什么不同?升级的地方用户能否感知?这里咱们就逐条展开,详细说说。

  频率翻倍,来自速度的双倍快乐;

  DDR5将直接从4800MHz起步,对比起2133MHz起步的DDR4,已经是翻倍的提升。对于高频内存,一些游戏用户应该比较熟悉。具体表现在某些游戏上,内存频率越高,游戏帧数越发稳定。对于一些创意类型软件,高频率内存加持同样能够让系统更加稳定流畅的运行。

  内存变得智能,可自我管理电压

  如果用户能够看到DDR5内存的裸条,会发现对比起DDR4,DDR5多了一组电子元器件。这组元器件便是电源管理IC,将原本在主板的元器件直接转移到来内存上,让内存能够独立自主的控制电压。DDR5的常见电压也因此降低到1.1V。对于电源管理IC,普通用户可能感知不大,但是对于喜爱超频的用户,将来以更低的电压去超频也是能够实现的。

  ECC功能加入,但并不是那个熟悉的ECC

  可能部分用户会听说DDR5内存加入了ECC纠错功能,但此ECC非彼ECC。在DDR5中加入的是On-die Ecc纠错功能。这里大家可以把它理解成ECC的低配版。On-die Ecc只能纠错内存内部,而常说的Ecc,一般会有额外的颗粒分配给Ecc功能,能纠错运行中通信上的错误。DDR5 UDIMM上的功能主要还是提高内存的稳定性,降低蓝屏概率。

  双双通道?DDR5再加车道

  许多用户都应该听说了DDR5内存可以实现单根双通道。这是对的,但也不完全对,为什么这么说呢,这里大家可以理解成原本DDR4内存只有一条64Bit通道传数据,双通道则为2 x 64bits,而DDR5是通过拆分为2条32Bits,从而达到所谓1DIMM 双通的效果。要达到达传统意义上双通道的理想值,还是需要使用2根内存的。

  综上所述,DDR5对比起DDR4在技术上是有着较大突破的,而国内各大厂商迅速做出跟进,发布旗下DDR5新品内存。七彩虹便推出旗下首款DDR5内存——战斧(BattleAX)DDR5 4800 Memory。新款战斧系列DDR5内存采用了全新的散热马甲设计,以经典的红黑配色为主,加入了赛车尾灯设计元素。同时马甲工艺上也进行了升级,新增了磨砂质感与使用了更加扎实的铝合金用料。这款内存起步频率也会在4800Mhz,并且有8G和16G两个版本。对于想要尝鲜的玩家们不妨去探索下DDR5所带来的最新提升。

  后续七彩虹也将推出更多高频,大容量的DDR5内存供用户尝鲜,比方说我们广受玩家认可的iGame系列极限超频内存已经正在路上。新品总是能让人兴奋,DDR5内存究竟还有多少未被发掘的潜能,让我们一起去探寻吧!

西安车主注意!残特奥会期间 限行规则有变化******

  10月16日,华商报记者从西安交警部门了解到,残特奥会期间,限行规则有变化。

  2021年9月1日,西安市公安局发布了十四运会和残特奥会机动车、载货汽车、危化品运输车交通管控措施和交通噪音污染管控措施,在全体市民的理解支持和社会各界的共同努力下,十四运会取得圆满成功。

  西安交警部门表示,为了确保残特奥会期间西安交通秩序稳定良好,更好实现保赛事和保民生的平衡,让交通管控措施更加精准、科学、便民,西安市公安局交警支队根据残特奥会赛事规模需求,结合我市交通管理实际,充分调研论证,对残特奥会期间机动车和载货汽车限行交通管控措施进行了微调,危化品车和交通噪音污染管控措施保持不变。

  另外,取消对外埠机动车全天、全号段限行,调整为和本地机动车一致,实行每日限行两个尾号。取消本市机动车(陕A、陕U号牌)绕城高速每日限行两个尾号。10月20日至10月29日限行尾号规则不变,10月30日后恢复原工作日尾号限行措施(10月30日周六、31日周日不限行);郊区县限行的尾号限行规则参照本规定执行。

  对绕城高速载货汽车限行管控时间进行调整,将原来限行时间每日7时至22时,调整为每日7时至9:30、17:30至20时。
