    1. In this study, a total of 187 unrelated Chinese probands enrolled from the 16 provinces of China had been diagnosed with LCA by retina specialists. Another cohort ascertained in this study as healthy control comprised 200 ethnically matched unrelated individuals. Detailed ocular examinations and routine physical examinations were performed to obtain clinical data about these participants in this study.

      CaseControlLabel: Aggregated *RPE65 variants in 187 apparently-unrelated Chinese probands from 16 provinces of China diagnosed with LCA by retina specialists and 200 ethnically matched apparently-unrelated healthy control individuals.

      CaseCohortLabel: 187 apparently-unrelated Chinese probands from 16 provinces of China diagnosed with LCA by retina specialists

      ControlCohortLabel: 200 ethnically matched apparently-unrelated healthy control individuals

      CaseControlPhenotype: HP:0003593 (Infantile onset), HP:0030555 (Best corrected visual acuity 0.2 LogMAR)

      CaseControlPhenotypeFreeText: The above phenotypes are noted only for the subset of LCA patients later found to have RPE65-related disease. Age at onset was within the first few months after birth. The best corrected visual acuity for individuals over 30 years old was less than 0.2, with few exceptions.

      CaseControlNOTPhenotype: N/A

      CaseDemographics: Country of origin for all case and control individuals is China, with recruitment area including all 16 provinces. Numbers of males and females, race, and age range are unspecified.

      ControlDemographics: Control individuals are stated to be ethnically matched to the cases, but details are not provided.

      CaseMethod: Previous testing for cases appears to have been limited to diagnosis of Leber's congenital amaurosis by a retina expert. Genotyping method was Sanger sequencing of PCR products from all 14 exons of RPE65. Targeted exome sequencing (194-gene panel) appears to have been performed for a subset of affected cases harboring RPE65 variants.

      ControlMethod: Previous testing was not described. Genotyping method was Sanger sequencing of PCR products from all 14 exons of RPE65.

      CasePower: 187 cases were genotyped, and 14 were found to harbor RPE65 variants (12 biallelic and 2 apparently monoallelic), with 11 cases predicted to harbor biallelic pathogenic RPE65 variants.

      ControlPower: The number of control individuals who harbored a variant in RPE65 is not mentioned.

      CaseAddInfo: Cases may have overlapped with other studies of Leber congenital amaurosis in Chinese cohorts (PMID: 29133760, PMID: 25356976, PMID: 26047050, PMID: 23661369, PMID: 22509104, PMID: 25383945, PMID: 21602930, PMID: 23661368, PMID: 28393863). The possibility of overlap is not addressed in the text.

      ControlAddInfo: Overlap of the control cohort with other PMIDs is not reported.

      CaseControlEvaluation: The study type is Aggregate analysis. The study used Sanger sequencing of the 14 exons of the RPE65 gene as the detection method. Cases counted were those found to harbor biallelic RPE65 variants that were predicted to be pathogenic at the protein level or demonstrated to have transcript-level impact through a minigene in vitro splicing assay.

      CaseControlStats: Test statistic value, p-value, and confidence interval are not included in the report.

      CaseControlBias: Matching was performed on the basis of ethnicity. While it is possible that age, gender, and other demographics were not as well-matched between cases and controls, the early onset of the disease makes these unlikely sources of bias. Because the process of matching is not described in detail, it is difficult to evaluate other sources of potential bias such as differences in local origin between cases and controls that might lead to false assumptions that certain individuals are unrelated.

      CaseControlComments: N/A

    1. El documento advierte de que la IA ofensiva se está convirtiendo en una capacidad operativa integrada en campañas reales y recomienda reforzar los controles esenciales, acelerar la gestión de vulnerabilidades, proteger las identidades, controlar la cadena de suministro y gobernar adecuadamente el uso de agentes.

      【方法】文章提到了CCN-CERT的指南,但没有详细说明这些控制措施的具体实施方法或有效性。需要了解这些推荐措施的技术细节,以及它们如何针对AI代理特有的攻击模式。此外,还需要了解这些措施的实际应用情况和效果数据。

    1. When a connection breaks, you should be able to find out why. And an administrator should be able to decide, down to the individual tool, what is available in each part of the organization.

      大多数人认为连接器故障排查应该简化,而工具访问控制应该采用更粗粒度的管理,但作者主张细粒度的故障诊断和工具级控制,这挑战了简化管理的行业趋势。

    1. The company said earlier this month that it received an export control directive from the Trump administration ordering the company to suspend access to its latest Claude models... 'by any foreign national, whether inside or outside the United States.'

      这揭示了文章中更广泛的背景:Anthropic最近面临政府监管压力。需要核实这一指令的具体内容、实施范围以及背后的国家安全考量。这表明AI技术出口限制与知识产权保护之间的复杂关系,以及中美科技竞争的最新动态。

    1. Filesystem controls were another important architectural choice. We found that offering different file-mount modes helps to granularly control risk; Claude Cowork offers read-only, read-write, and read-write-no-delete.

      行动建议:实现细粒度的文件系统访问控制,提供多种挂载模式(如只读、读写、读写但不删除)来精确控制风险。对于企业环境,还应实现路径允许列表功能,并通过MDM设置进行管理,防止符号链接等机制导致的边界逃逸。

    1. export controls are leakier than previously understood

      【洞察】「出口管制比之前理解的更加漏洞百出」——这句话是对整个西方 AI 地缘政治战略的严厉评价。更令人不安的是:如果走私渠道如此有效,那么比芯片更容易传输的「模型权重」和「训练技术」的扩散速度只会更快。硬件管制是可见的,但知识扩散是不可见的。Epoch AI 的数据与 Anthropic 指控中国公司「蒸馏」其模型放在一起读,呈现出一幅完整的算力与知识双重扩散图景。

    2. our central estimate is around 660,000 H100-equivalents

      【令人震惊的数字】走私流入中国的算力中位估算:66 万个 H100 等效——约占中国 AI 算力总量的三分之一。这个数字彻底改变了「出口管制正在有效阻断中国 AI 发展」的主流叙事。如果三分之一的算力来自走私,那么所有基于「中国无法获得先进芯片」假设的中美 AI 差距分析,都需要用这个修正系数重新计算。

    3. We estimate that between 290,000 and 1.6 million H100-equivalents (H100e) were smuggled to China through 2025. Our median estimate of 660,000 H100e would be roughly a third of China's total compute.

      大多数人认为美国出口管制能有效遏制中国获取先进AI芯片,但作者认为这些管制实际上导致大量芯片被走私到中国,走私数量可能与中国合法获取的芯片数量相当,这意味着出口管制的效果远不如预期。

    1. These figures include Nvidia and AMD datacenter GPUs, Google TPUs, Amazon Trainium and Inferentia chips, and Huawei's AI chips. We estimate that these five categories encompass the vast majority of the world's dedicated AI computing power.

      这个清单里藏着一个地缘政治炸弹:华为 AI 芯片被并列纳入「全球主要算力」统计。这意味着即便在出口管制和制裁下,华为的算力存量仍然大到不可忽视。中国 AI 算力的真实规模因此比西方媒体描述的更接近全球主流水平——「算力脱钩」的叙事可能严重低估了中国的实际积累。

    1. Aortic dissection typically presents acutely with sudden, severe tearing chest or back pain, often described as lancinating in quality. [5-6] Approximately 50% of patients with thoracic aortic aneurysm may progress to dissection without timely intervention. [5] In contrast, thoracic aortic aneurysm is usually asymptomatic and discovered incidentally during physical examination or imaging for other indications. [5]

    1. it's not a technological advantage that you have it is a political advantage and an organizational advantage here in China The People's Bank the Central Bank of China controls the bankers in the United States the bankers control the central bank they own the central bank they created the Central Bank the Central Bank of the United States the Federal Reserve was created by JB Morgan it was not the other way around
