Houston leaders seek clues for concert mishap that killed 8******

Reuters。

People place flowers at NRG Park, after a deadly crush of fans during a performance the day before at the Astroworld Festival by rapper Travis Scott in Houston on Saturday.。

Authorities said they would watch video, interview witnesses and review concert protocols to determine how eight people died at a Houston music festival when fans suddenly surged toward the stage to watch rapper Travis Scott.。

City officials said on Saturday they were in the early stages of investigating the pandemonium that unfolded on Friday evening at Astroworld, a sold-out, two-day event in NRG Park with an estimated 50,000 people in attendance. One attendee said that as a timer clicked down to the start of Scott's performance, the crowd pushed forward.。

"As soon as he jumped out on the stage, it was like an energy took over and everything went haywire," fan Niaara Goods said. "All of a sudden, your ribs are being crushed. You have someone's arm in your neck. You're trying to breathe, but you can't."

Goods said she was so desperate to get out that she bit a man on the shoulder to get him to move.。

The dead ranged in age from 14 to 27, and 13 people were still hospitalized on Saturday, Mayor Sylvester Turner said. He called the disaster "a tragedy on many different levels" and said it was too early to draw conclusions about what went wrong. Dozens were injured.。

"It may well be that this tragedy is the result of unpredictable events, of circumstances coming together that couldn't possibly have been avoided," said Judge Lina Hidalgo, Harris County's top elected official. "But until we determine that, I will ask the tough questions."

Experts who have studied deaths caused by crowd surges say they are often a result of density – too many people packed into a small space. The crowd is often running either away from a perceived threat or toward something they want, such as a performer, before hitting a barrier.。

G Keith Still, a visiting professor of crowd science at the United Kingdom's University of Suffolk, has testified as an expert witness in court cases involving crowds. He said he usually does not look at eyewitness reports in the early stages of analyzing an incident because emotions can cloud the picture, and witnesses can see only what's immediately around them.。

Based on fire codes, the venue could have held 200,000 people, but city officials limited the attendance to 50,000, Houston Fire Chief Samuel Pena said.。

"It was the crowd control at the point of the stage that was the issue, especially as the crowd began to surge toward the stage," Pena said.。

People in the Houston crowd reported lots of pushing and shoving during the performances leading up to Scott's set.。

Then when Scott took the stage, the crowd seemed to rush to the front, trying to get closer to the stage, said Nick Johnson, a high school senior from a Houston suburb who was at the concert.。

"Everyone was passing out around you, and everyone was trying to help each other. But you just couldn't move. You couldn't do anything. You can't even pick your arms up," Johnson said. "It just got worse and worse."

Johnson said fans started to crush each other, and people started screaming.。

Scott seemed to be aware that something was going on in the crowd, but he might not have understood the severity of the situation, he added.。

A social media posting shows fans who appear to be dozens of rows from the stage chanting "stop the show" while Scott is performing. Another post shows two fans climbing a ladder aboard a platform and asking a cameraman to do something.。

On video posted to social media, Scott could be seen stopping the concert at one point and asking for aid for someone in the audience: "Security, somebody help real quick."

In a tweet posted on Saturday, Scott said he was "absolutely devastated by what took place last night." He pledged to work "together with the Houston community to heal and support the families in need."

Amy Harris, a freelance photographer, described an "aggressive" crowd atmosphere throughout the day because of the way fans were behaving – pushing and rushing the stage barricades and prohibited VIP and admission areas.。

"It was definitely the most chaotic festival environment that I've been in," Harris said. "I felt uneasy all day."

Scott, one of music's biggest young stars, founded the Astroworld Festival in 2018. The 29-year-old Houston native has been nominated for eight Grammy Awards. He has a 3-year-old daughter with Kylie Jenner, who announced in September that she's pregnant with their second child.。

LCD驱动器严重短缺:价格疯狂上涨******国际数据公司(IDC)的分析师Linn Huang表示,当前最短缺的组件是用于面板的组件,也就是驱动LCD。

芯片短缺这个问题是众所周知的,但大多人都认为造成这种局面是微处理器导致的。但事实证明,LCD驱动器正在对全球造成最严重的影响。LCD驱动器用于显示器、个人电脑、笔记本电脑、汽车、智能手机和几乎所有带有数字液晶面板的产品,向像素提供指令。

尽管芯片短缺一直是半导体行业的话题,但鲜为人知的集成电路(IC)在生活中发挥的作用要比价格更高的同类产品大得多。

国际数据公司(IDC)的分析师Linn Huang表示,当前最短缺的组件是用于面板的组件,也就是驱动LCD。

IDC半导体分析师Shane Rau表示,任何带有液晶面板的产品,比如电视、手机或平板电脑,但主要是笔记本电脑,你都需要一个带有液晶驱动的芯片。

惠普公司首席执行官恩里克 洛雷斯(Enrique Lores)在伯恩斯坦研究公司(Bernstein Research)战略决策会议(Strategic Decisions Conference)上证实了这一观点。

美国德克萨斯州奥斯汀的显示器供应链咨询公司(DSCC)的联合创始人、负责人和首席财务官鲍勃 奥布莱恩 (Bob O 'Brien)表示,在过去12个月里,电视面板的价格上涨了一倍。

美国劳工统计局(Bureau of Labor Statistics)发布的美国消费者价格指数月度报告显示,4月份个人电脑价格折合成年率上涨81%,创历史新高。

尽管5月份CPI下降至8%,与上周公布的总体消费者价格涨幅一致,但专家们预计未来还会出现更多价格上涨。IDC的黄林认为,当假日购物季开始时,价格将开始上涨。

惠普公司和戴尔公司在2020的业绩电话会议上都提到了价格上涨。

事实上,低成本的LCD驱动的价格已经上涨,但这些价格之前一直是1美元左右的一个部件。

奇景光电科技公司(Himax)的首席执行官Jordan Wu表示,与成本较高的CPU、GPU或内存芯片相比,LCD驱动器的芯片的供应更少,因为LCD驱动器使用的是低端制造流程,外包制造服务的半导体代工厂正在逐步淘汰这种流程。

而英特尔(Intel)和AMD等微处理器公司则是全球最大的微处理器制造商。AMD正在争夺10纳米、7纳米或更低纳米芯片的最先进制造能力,而像Himax这样的公司则在40纳米至150纳米的工艺节点上制造芯片。

在截至3月31日的第一季度,Himax的收入同比增长67%,至3.09亿美元。增长的一个主要领域是笔记本电脑的驱动,其销量连续增长了70%,但由于代工产能不足,监控IC销量连续下降。

该公司的股价从去年的3.3美元飙升了约14美元,该股价飙升了366%。

Jordan Wu预计,在2023年之前,半导体供需状况不会达到平衡。
