Salih Djilali
This study investigates a diffusive infection age-structured SIS epidemic model with a Neumann boundary condition, which is a generalization of the model studied in [Allen et al., Asymptotic profiles of the steady states for an SIS epidemic...
A general class of bounded diffusion processes with applications in the biosciences [0.03%]
一类有界扩散过程的通用类及其在生物科学中的应用
Karl Larsson
Karl Larsson
This paper develops and analyzes a unified class of bounded continuous-time diffusion processes defined by stochastic differential equations. The models share a common random component but differ in their drift specification, encompassing p...
Reshaping transmission and recovery: How memory effects govern global dynamics thresholds in the SIR model [0.03%]
重塑传输和恢复：记忆效应如何决定SIR模型中的全局动力学阈值
Zhaohua Wu,Yongli Cai,Zhiming Wang et al.
Zhaohua Wu et al.
Biological processes inherently operate with memory: past infections modulate present transmissibility, and cumulative immune experience shapes future recovery. Conventional epidemic models, however, largely neglect such history-dependent m...
Juvenile-adult asymmetry in species interactions and risk-taking behavior: mechanisms governing population stability [0.03%]
Guangjing Qian,Jiawen Chen,Yan Lu et al.
Guangjing Qian et al.
Within-species size variation is known to create asymmetries in resource competition and, increasingly, is recognized to correlate with systematic shifts in behavioral responses (e.g., boldness) between juveniles and adults. The combined ef...
Dynamics in an almost periodic metapopulation with competition and habitat destruction: An exponential dichotomy based approach [0.03%]
基于指数二分法的具有竞争和栖所破坏的几乎周期元种群动态学研究
Pablo Amster,Gonzalo Robledo,Daniel Sepúlveda
Pablo Amster
This paper explains how the theory of exponential dichotomy allows to carry out the study of an almost periodic version of a metapopulation model developed in the 90's, which generalizes the classical Levins approach by considering species ...
Optimal experiment design for practical parameter identifiability and model discrimination [0.03%]
具有实际参数可识别性和模型区分性的最优实验设计
Yue Liu,Philip K Maini,Ruth E Baker
Yue Liu
Mechanistic mathematical models of biological systems usually contain a number of unknown parameters whose values need to be estimated from available experimental data in order for the models to be validated and used to make quantitative pr...
Time Evolution of Infection State Correlation of Nodes in an SIR Model on a Random Contact Network [0.03%]
SIR模型中随机接触网络内节点感染状态的相关性及其演化
Meili Li,Haodong Shi,Junling Ma et al.
Meili Li et al.
Traditional network epidemic models often assume that the infection states of a node's neighbours are independent, an assumption that is commonly used to approximate triple-node interactions by pairwise ones. However, this assumption is gen...
Dynamical Analysis of Heterogeneous Epidemic Models with Discrete and Continuous Contact Variation [0.03%]
具有离散和连续接触变化的异质流行病模型的动力学分析
Jiangmin Li,Zhen Jin,Ming Tang et al.
Jiangmin Li et al.
Discrete representations of contact heterogeneity have been widely studied in epidemic modeling, but their limitations in capturing contact-level variation motivate continuous formulations. While recent extensions to continuous heterogeneit...
Stoichiometric constraints and cooperative hunting reshape tri-trophic food-chain dynamics and trophic transfer efficiency [0.03%]
计量学限制和协同狩猎重塑三营养级食物链动态及营养级传递效率
Zhiwei Zhu,Tao Feng
Zhiwei Zhu
Cooperative hunting by social carnivores is widespread, but its interplay with nutrient stoichiometry in tri-trophic food chains remains poorly understood. We develop a stoichiometrically explicit producer-herbivore-carnivore model in which...
The dynamics of hepatitis B transmission with treatment and vaccination: A case study in the Ili Region of Xinjiang, China, by a physics-informed neural networks approach [0.03%]
结合治疗和疫苗接种的乙型肝炎传播动力学：利用基于物理信息的神经网络方法对中国新疆伊犁地区的案例研究
Xiaomei Feng,Yuan Chen,Cheng Cheng et al.
Xiaomei Feng et al.
Hepatitis B virus (HBV) infection remains a leading cause of cirrhosis and hepatocellular carcinoma worldwide, and long-term control relies on sustained immunization and effective reduction of transmission. In high-burden settings, vaccinat...
