Construction And Application Of Clinical Evidence Framework For Brain-Computer Interface, Wenxiu Qi, Cheng Zhou

Bulletin of Chinese Academy of Sciences (Chinese Version)

Brain-computer interface systems are emerging neurotechnologies that are gradually moving from laboratory research toward clinical application. However, their inherent features, including small sample sizes, heterogeneous technical pathways, and rapid product iteration, make it difficult to integrate safety and efficacy data across studies or to conduct meaningful cross-study comparisons. These challenges not only hinder the cumulative development of evidence in evidence-based medicine, but also complicate the assessment of clinical access and regulatory review. In addition, subjective evidence, such as patient experience, remains insufficiently captured in existing evaluation frameworks. It is therefore necessary to examine the structure of evidence for brain-computer interface …

Impact And Mechanisms Of Social Economic Status On Accessibility Of Public Services, Youlang Zhang, Yefei Yu, Xufeng Zhu

Bulletin of Chinese Academy of Sciences (Chinese Version)

Balanced and equitable access to public services is a core element of high-quality development and is frequently emphasized in policy documents. Nevertheless, existing literature lacks attention to the conceptual elaboration and micro-level mechanisms of the accessibility of individual public services. Social economic status serves as a comprehensive and widely meaningful indicator of differences among individuals. This study argues that accessibility reflects the degree of adaptation between supply and demand in public services based on government-citizen interactions. The study proposes a unified analytical framework including public resources and capabilities on the demand side and administrative procedures on the supply side, aiming …

Veterans' Benefits Exceptionalism After Axon: Johnson V. U.S. Congress And The Future Of Structural Constitutional Review In Va., Robert Molina

ConLawNOW

This Essay addresses the pending case before the U.S. Supreme Court, Johnson v. U.S. Congress, and argues that the Court should resolve the tension between regular federal jurisdiction and specialized administrative court jurisdiction for veterans’ benefits claims. Veterans’ benefits exceptionalism, it asserts, should not overcome the usual federal court process. Ordinary benefits-entitlement claims, and some statutory-validity claims, may properly remain in the specialized pipeline established by the Veterans’ Judicial Review Act. But structural constitutional challenges to the Veterans Administration adjudicatory apparatus should receive immediate district court review when they satisfy the three-factor test the Court applies to determine whether …
