Two-layer hierarchical MPPT strategy of PV systems based on AF-EPO algorithm under complex irradiance conditions

Lei Wang, Jinzhao Cui, Chao Ge, Zhixin Lun

Photovoltaic power generation systems exhibit multi-peak power-voltage characteristics under partial shading conditions, severely limiting the effectiveness of conventional maximum power point tracking methods. This paper proposes a two-layer hierarchical MPPT architecture based on an adaptive fuzzy-weighted eagle perching optimization algorithm, designated AF-EPO. …

AI Agents and Epidemic Intelligence on Respiratory Infectious Diseases: Toward a Conceptual Framework Integrating Decision Support

Liuyang Yang, Liyu Shan, Xiaolin Cao, Jinzhao Cui et autres

Unlabelled: Traditional epidemic intelligence relies heavily on human epidemiologists for data interpretation and reporting, which makes it resource intensive, slow to respond, and vulnerable to variability in professional expertise. To overcome these limitations, we propose an expanded conceptual epidemic intelligence quadripartite framework …

Probability-Based Early Warning for Seasonal Influenza in China: Model Development Study

Jinzhao Cui, Ting Zhang, Xiaoli Wang, Liuyang Yang et autres

Background: Seasonal influenza is a major global public health concern, leading to escalated morbidity and mortality rates. Traditional early warning models rely on binary (0/1) classification methods, which issue alerts only when predefined thresholds are crossed. However, these models exhibit inflexibility, often …

From Binary to Probability: A Machine Learning-Based Early Warning System for Seasonal Influenza in China (2014–2024) (Preprint)

Jinzhao Cui, Liuyang Yang, Ting Zhang, Xuefeng Huang et autres

BACKGROUND Seasonal influenza remains a major global public health concern, causing substantial morbidity and mortality. Traditional early warning models rely on binary (0/1) classification methods, issuing alerts only when predefined thresholds are crossed. However, these models lack flexibility, often leading to false …

Effectiveness of Enterovirus 71 inactivated vaccines against hand, foot, and mouth disease: A test-negative case-control study

Yutong Zhang, Jinzhao Cui, Fengfeng Liu, Yang Song et autres

The Enterovirus A71 (EV-A71) vaccine was introduced in China in December 2015 as a preventive measure against hand, foot, and mouth disease (HFMD) caused by EV-A71. However, the effectiveness of the vaccine (VE) in real-world settings needs to be evaluated. We conducted …

MPPT Control of Photovoltaic Power Generation System Based on Improved Eagle Perching Optimization Algorithm

Jinzhao Cui, Hong Wang, Chao Ge, Changchun Hua

Photovoltaic power generation system is susceptible to temperature and light conditions, and its P-V curve shows multiple peaks, which reduces the effectiveness of the traditional maximum power point tracking method. Aiming at this problem, the eagle perching optimization algorithm (EPO) is introduced …
