惊声尖笑

A |     OKLAHOMA CITY -- An Oklahoma judge on Tuesday exonerated a man who spent 30 years in prison for a 1987 rape and burglary, after post-conviction DNA testing from a rape kit showed he did not commit the crime.Pontotoc County District Judge Steven Kessinger issued a final order that vacates Perry Lott's conviction and permanently dismisses the case. “I have never lost hope that this day would come,” Lott, 61, said in a statement. "I had faith that the truth would prevail, even after 35 long years.“I can finally shut this door and move on with my life.”Lott was released from prison in 2018 after the DNA results first came to light, but only after agreeing to a deal with former District Attorney Paul Smith to modify his sentence. The agreement allowed Lott to leave prison and remain free while his motion to vacate was litigated. At the time, Smith said the DNA evidence did not exclude Lott as a suspect.But earlier this year, the Innocence Project, which helped to free Lott, approached newly elected District Attorney Erik Johnson, who reviewed the case and agreed the conviction should be vacated.“Five years ago, all evidence pointed to his innocence, but he was denied justice,” Innocence Project Senior Staff Attorney Adnan Sultan said in a statement. "We are grateful to District Attorney Erik Johnson for his commitment to righting this wrong.”Oklahoma state law requires a conviction to be vacated in order for a wrongfully convicted person to be able to seek up to $175,000 in compensation from the state.Lott's case occurred around the same time and in the same county as the convictions of Tommy Ward and Karl Fontenot, whose cases have come under intense scrutiny and have been the subject of numerous books, including John Grisham's “The Innocent Man,” which he produced into a six-part documentary on Netflix. A federal judge ordered Fontenot released, but Ward remains in prison.The books and documentary also feature the high-profile exoneration of Ron Williamson and Dennis Fritz, who both were convicted in the same county for the 1982 killing of Ada waitress Debra Sue Carter. That case featured the same cast of investigators and prosecutors, along with the same jailhouse informant who testified against Ward and Fontenot. Williamson at one point came within days of being executed. Both were later freed.。    

快科技8月24日消息，博主定焦数码指出，在应用逻辑折叠技术之前，华为麒麟芯片的等效晶体管密度与台积电5nm基本相当。而在引入逻辑折叠技术之后，其水平至少能达到台积电第一代3nm工艺的水准，甚至有可能更强。据悉，华为Mate 90系列将搭载全新的韬定律麒麟芯片，该芯片率先采用逻辑折叠技术，堪称国产芯片领域的一次史诗级突破。在电路层面，通过逻辑折叠技术突破了传统平面布局的物理边界，显著缩短了关键路径的走线长度，并有效降低了信号传播过程中的电阻和电容负载，从而实现了晶体管密度和电路性能的大幅提升。在芯片层面，通过“软件、架构、芯片”的全栈软硬芯协同设计，基于实际工作负载对指令流和数据流进行细粒度控制，显著提高了系统级并行度和效率，大幅缩短了端到端的执行时间。

B | 根据华为的规划，预计到2031年，基于韬定律的高端芯片晶体管密度将达到与1.4纳米制程同等的水平。韬定律的落地将全方位提振国内芯片产业的信心，利好全产业链的协同发展。短期来看，将直接带动国内半导体材料、制造、封测等上下游企业的成长；长期来看，华为这套技术方案为国内芯片设计企业规避先进制程受限风险、突破技术瓶颈，提供了一条全新的可行路径。首发搭载韬定律麒麟芯片的华为Mate 90系列，将于9月正式登场。
