The emergence of SARS-Co V-2 variant of concern omicron BA.2 led to high infection incidence rates as well as reduced severity of COVID-19 during the Shanghai Spring epidemic of 2022 [1]. We assessed the role of viral pathogenicity and the effectiveness of inactivated vaccines in a retrospective observational study including 10 258 confirmed COVID-19cases identified between April and June of 2022, from four COVID-19 designated hospitals located in two areas of Shanghai, namely the West Bund and the East Bund, where the populations’ demographic characteristics varied significantly (Table S1, Fig. S1).

随着大数据技术的发展,个人信息的泄露和滥用问题日益严重,个人信息受到侵害的案件频繁发生,给大众的人身和财产带来一定程度的损害。在大数据背景下,个人信息的刑法保护已经成为一个重要的议题,公民个人信息的刑法保障更加急迫和艰难。为了保护个人信息的安全和隐私,许多国家和地区都制定了相应的个人信息保护法律和规定,然而我国个人信息刑法保护仍存在一定的迟延性。因此,文章以大数据和个人信息为切入点,通过探究我国进入大数据时代以来,刑法对个人信息的保护力度和基本状况,总结司法实践中刑法关于个人信息保护存在的一些不足之处。基于上述问题,针对个人信息刑法保护问题,文章提出了相关建议,期望能够进一步完善我国针对个人信息保护的刑法体系。

随着城市化进程加速，如何规划管控和活化利用城市中的残余农田成为城市发展中的重大问题。从认知“城中田”的潜在复合价值切入，通过文献研究归纳“城中田”在生态、城市食物系统、社会三方面的潜在价值；结合现实调研，发现当前“城中田”保护存在法规政策真空、实效管理缺位、功能定位单一和负外部性冲突等现实困境；依据国家政策的演进趋势分析与土地利用方式的综合绩效比较，推导活化利用“城中田”的许可逻辑与可能导向；最后聚焦“功能复合、生态提升、生产保障”三大诉求，提出未来“城中田”规划的路径思考，以期为“城中田”的价值认知和保护利用方式提供指引。

The key to solve increasingly severe electromagnetic(EM)pollution is to explore sustainable,easily prepared,and cost-effective EM wave absorption materials with exceptional absorption ***,instead of anchoring on carbon materials in single layer,MoS_(2) flower-like microspheres were stacked on the surface of pomelo peels-derived porous carbon nanosheets(C)to fabricate MoS_(2)@C nanocomposites by a facile solvothermal *** wave absorption performances of MoS_(2)@C nanocomposites in X-band were systematically investigated,indicating the minimum reflection loss(RLmin)of-62.3 dB(thickness of 2.88 mm)and effective absorption bandwidth(EAB)almost covering the whole X-band(thickness of 2.63 mm)with the filler loading of only 20 wt.%.Superior EM wave absorption performances of MoS_(2)@C nanocomposites could be attributed to the excellent impedance matching characteristic and dielectric loss capacity(conduction loss and polarization loss).This study revealed that the as-prepared MoS_(2)@C nanocomposites would be a novel prospective candidate for the sustainable EM absorbents with superior EM wave absorption performances.
