一 | Ankara, Oct 15 (UNI) At least 28 people have died and dozens remain trapped underground after an explosion in a coal mine in northern Turkey's Bartin province.
Around 110 people were in the mine at the time of the blast on Friday, almost half of them at over 300 metres deep, BBC reported.
Turkey's Health Minister Fahrettin Koca said 11 people had been rescued and were being treated.
Emergency crews worked through the night, digging through rock to try to reach more survivors.
Video footage showed miners emerging blackened and bleary-eyed accompanied by rescuers at the facility in Amasra, on the Black Sea coast, the BBC reported.
The family and friends of the missing could also be seen at the mine, anxiously awaiting news of their loved ones.
The explosion is believed to have occurred at around 300 meters deep. At least 49 people were working in the "risky" zone between 300 and 350 meters (985 to 1,150 feet) underground, Interior Minister Suleyman Soylu said.
The cause of the blast is not yet known, and the local prosecutor's office has begun an investigation.
The mine belongs to the state-owned Turkish Hard Coal Enterprises.

二 | 英伟达透露，Vera CPU已于 6 月交付给客户，包括OpenAI、Anthropic和SpaceX。
三 | 此外，英伟达于当地时间7月21日通过博客透露了更多关于Vera Rubin平台的信息。
四 | Vera Rubin平台包括7颗芯片和5个机架。英伟达表示，Vera Rubin平台正在加快走向吉瓦级规模部署。
五 | Vera Rubin拥有覆盖全球30个国家、350个制造基地的供应链体系，是有史以来最大规模、最成熟的机架级供应链。 英伟达称，Vera Rubin平台从芯片到架构都进行了优化，实现了每瓦最高性能和最低的token（词元）成本。CoreWeave在DeepSeek-R1上的测试结果显示，Vera Rubin平台的每兆瓦吞吐量是上一代Grace Blackwell NVL72的10倍，这对电力供应受限的AI工厂而言是十分重要的指标。
六 | 对于Vera平台的不同产品，英伟达表示，Vera CPU专为智能体时代设计，其定制化的Olympus核心单线程性能提升了2倍，核间带宽提升了3倍，相比同类小芯片设计，这颗芯片是处理关键智能体工作负载时最高效的单线程（single-threaded）CPU。 网络方面，第六代NVLink在复杂工作负载下能提供超过2倍的吞吐量，将延迟降低3倍。横向扩展方面，Spectrum-X以太网结合了102.4T的Spectrum-6交换机系统、1.6T ConnetX-9 SuperNIC网卡等，使RDMA带宽达到市面上以太网产品的1.6倍。CoreWeave、微软、SpaceX和特斯拉已率先引入Spectrum-6。 Vera Rubin NVL72的生产则在加速。英伟达表示，相关机架已经在合作伙伴CoreWeave、谷歌云、微软Azure和甲骨文云基础设施上运行。Vera Rubin NVL72机箱内无电缆、风扇或软管，计算模块组装时间已从数小时缩短至一分钟，采用45摄氏度液冷入口设计，可实现无需冷水机的干式冷却运行。英伟达表示，对于新建的AI工厂，这种高温干式冷却结合闭环液冷系统，每年每兆瓦可节约数百加仑的用水量。 此外，英伟达表示，Vera Rubin平台是微软与法国AI公司Mistral合作的基础。这两家公司计划投入数十亿美元在欧洲建设算力基础设施。Mistral正在部署数千块最新的Vera Rubin GPU，增加其GPU容量，以提升客户的AI计算资源可用性。 英伟达CEO黄仁勋在上个月的股东大会上也提到Vera Rubin平台，称Vera Rubin是为智能体打造的，Vera Rubin已经全面投产，每个主要的模型开发商、公有云、AI云和超大规模云厂商都准备基于Vera Rubin进行建设，Vera CPU已经开始有订单。此前英伟达还预计，Vera CPU为公司打开了2000亿美元的全新市场。 (本文来自第一财经)。
