Integrated multi-omics analysis suggests a potential mechanism of DEHP-induced monocyte infiltration in MASH via the FOS-CCL3/4 axis

Chaojie Wang, Zhihao Zhang, Yuqing Huang, Yandan Shi, Peng Lei

OBJECTIVE: Di-(2-ethylhexyl) phthalate (DEHP) is a widespread environmental obesogen; however, its immune-proinflammatory mechanisms in the progression of metabolic dysfunction-associated steatohepatitis (MASH) remain incompletely elucidated. This study aims to comprehensively ch…

When Agents Go Rogue: Activation-Based Detection of Malicious Behaviors in Multi-Agent Systems

Haowen Xu, Xue Tan, Lei Ma, Zhihao Zhang, Chao Wang, Qingze Wang, et al.

While enabling effective collaboration on complex tasks, LLM-based Multi-Agent Systems (MAS) face critical security challenges due to vulnerabilities at the agent and interaction levels. Most existing MAS security defenses are built upon two core assumptions: semantically-explici…

AgentGym2: Benchmarking Large Language Model Agents in De-Idealized Real-World Environments

Zhiheng Xi, Dingwen Yang, Jiaqi Liu, Jixuan Huang, Honglin Guo, Baodai Huang, et al.

Language agents, i.e., LLM agents, progress rapidly and are increasingly deployed in production environments. This trend underscores the urgent need for rigorous and realistic evaluations. However, most existing benchmarks evaluate agents in simplified, idealized settings. They t…

CORE Planner: Contextual-memory Oriented Reinforcement-learning in Unknown Environments for Robot Navigation

Jintao Kong, Zhihao Zhang, Weihuang Chen, Liming Chen, Zhongyu Guo, Shuaiyu Liu, et al.

Autonomous navigation in unknown environments requires a robot to efficiently reach a predefined goal while exploring without prior maps. Although progress has been made in this area, most existing works still rely on traditional planning methods with hand-crafted rules, while le…
