On the mean-field limit of Vlasov–Poisson–Fokker–Planck equations

Li Chen, Jinwook Jung, Peter Pickl, Zhenfu Wang

The derivation of effective descriptions for interacting many-body systems is an important branch of applied mathematics. We prove a propagation of chaos result for a system of N particles subject to Newtonian time evolution with or without additional white noise influencing the …

A Combined FEM-CFD Method for Investigating Transport Properties of Compressed Porous Electrodes in PEMFC: A Microstructure Perspective

Zhuo Zhang, Ruiyuan Zhang, X. Zhang, Z. Tang et autres

Hydrogen energy is vital for a clean, low-carbon society, and proton exchange membrane fuel cells (PEMFCs) represent a core technology for the conversion of hydrogen chemical energy into electrical energy. When PEMFC single cells are stacked under assembly force for high power …

Local Existence of Classical Solution to the Chemotaxis‐Shallow Water System With Vacuum in ℝ2

Li Chen, Zhen Luo

ABSTRACT In this paper, we consider the chemotaxis‐shallow water system in . We establish the local existence of classical solution without assuming the initial height is small or has a small perturbation near a constant. The far field behavior of the height …

Engineered gold nanoparticle-based miRNA precision regulation for tumor diagnosis and synergistic therapy

Li Chen, Haoyu Wang, Handan Zhang, Wenyun Mu et autres

Cancer remains a major global health challenge, with traditional therapies such as chemotherapy, radiotherapy, and surgery often limited by side effects, drug resistance, and incomplete tumor eradication. Recent advances in molecular biology have highlighted the dual role of microRNAs (miRNAs) in cancer, …

Ice Cream Doesn't Cause Drowning: Benchmarking LLMs Against Statistical Pitfalls in Causal Inference

Du Jin, Li Chen, Xun Xian, An Luo et autres

Reliable causal inference is essential for making decisions in high-stakes areas like medicine, economics, and public policy. However, it remains unclear whether large language models (LLMs) can handle rigorous and trustworthy statistical causal inference. Current benchmarks usually involve simplified tasks. For example, …

Remodeling of Effector and Regulatory T Cells by Capture and Utilization of miRNAs Using Nanocomposite Hydrogel for Tumor-Specific Photothermal Immunotherapy

Li Chen, Man Zhu, Handan Zhang, Wenjun Tang et autres

In immunotherapy for malignant tumors, the dysregulation of the balance between effector T cells and regulatory T cells (Tregs) and the uncertain efficacy due to individual differences have been considered as two critical challenges. In this study, we engineered an injectable nanocomposite …

Intelligent gold nanocluster for effective treatment of malignant tumor via tumor-specific photothermal–chemodynamic therapy with AIE guidance

Feng Liu, Tianfeng Yang, Xiaowei Chang, Li Chen et autres

ABSTRACT Precise and efficient therapy of malignant tumors is always a challenge. Herein, gold nanoclusters co-modified by aggregation-induced-emission (AIE) molecules, copper ion chelator (acylthiourea) and tumor-targeting agent (folic acid) were fabricated to perform AIE-guided and tumor-specific synergistic therapy with great spatio-temporal controllability …
