Investigation of salt-bridge interactions underlying salt activation of halophilic methionine sulfoxide reductase A

Shuhong Chen, Lianghui Liu, Hailang Zhou, Xiaoxue Kuang et autres

Introduction Halophilic microorganisms inhabit hypersaline environments where sustained ionic stress challenges protein structure and function, making salt-responsive enzymes important for cellular fitness. Here, we investigated the salt-bridge interactions that support salt-dependent activation of a halophilic methionine sulfoxide reductase A from Halobacterium hubeiense …

Game theory-driven multi-level perturbation ensemble adversarial attacks

Shuhong Chen, Mengmeng Tang, Hanjun Li, Zhili Zhou et autres

对抗攻击是深度神经网络面临的主要安全威胁,其生成的对抗样本具有跨模型的攻击可迁移性.集成对抗攻击通过融合多模型优势,显著增强了攻击迁移效果.然而,现有方法多关注扰动生成策略的优化,忽视了模型间差异性对迁移能力的影响.本文从博弈论的视角分析了集成攻击中多模型间的协作与策略权衡问题,并提出一种博弈论驱动的多层次扰动集成对抗攻击GMPE.该方法基于Shapley边际贡献分配集成攻击权重,最大化模型的贡献,从而进一步提高生成对抗样本的可转移攻击能力和可解释性.本文进一步提出多层次扰动生成及梯度集成策略,通过内部迭代机制的设计, 将模型多样性引入到攻击生成过程的动态采样中,更精确地捕捉整体模型对抗方向,显著增强了对抗样本的攻击成功率.本文在 NIPS 2017 和 ILSVRC 2012 两个公开数据集上验证了所提出方法的有效性,相对于最先进的攻击方法, GMPE不仅显著提高了攻击成功率,同时具有较好的可迁移性.

Characteristics of CVA16 B1c strains isolated for the first time in the Heilongjiang Province of China

Tingting Yang, Qiang Sun, Hui Liu, Ming Yang et autres

Hand, foot, and mouth disease (HFMD) represents a globally prevalent infectious disease that is caused by enteroviruses. Enterovirus A71 (EV-A71), coxsackievirus A16 (CVA16), and coxsackievirus A6 (CVA6) are recognized as the predominant causative agents of HFMD. CVA16 is a member of the …

Comparative Analysis of microRNA Expression Profiles of Exosome-Mimetic Vesicles, Exosomes, and Originating Human Bone Marrow Mesenchymal Stem Cells

Congya Zhang, Shuhong Chen, Guyan Wang

Exosomes derived from mesenchymal stem cells (MSCs) show therapeutic potential despite limited yield. In contrast, the yield of exosome-mimetic vesicles (EMVs), which share a similar structure and size with exosomes is high. Previous studies have compared their proteomic profiles, and the microRNA …
