Global Stability for an SEIR Epidemiological Model with Varying Infectivity and Infinite Delay [PDF]
, 2009 A recent paper (Math. Biosci. and Eng. (2008) 5:389-402) presented an SEIR model using an infinite delay to account for varying infectivity. The analysis in that paper did not resolve the global dynamics for R0 \u3e 1.

, 2016 The main purpose of this work is to investigate the qualitative behavior of an HIV dynamics model with two types of cocirculating target cells. The model takes into account both short-lived and long lived chronically infected cells.

OPTIMAL CONTROL OF A TWO TEAMS PREY-PREDATOR INTERACTION MODEL
, 2015 In this paper, a model of two teams of predators interacting with two teams of preys is proposed. The predator teams help each other and so do the prey teams.

International Journal of Mathematics and Mathematical Sciences, Volume 2025, Issue 1, 2025.In this paper, we propose a viral model with cell‐to‐cell propagation, delayed saturated CTL immunity, and general incidence rate. Two biological threshold parameters, namely, the basic reproductive number R0 and the CTL immune reproductive number R1, are derived.

Central limit approximations for Markov population processes with countably many types [PDF]
, 2012 When modelling metapopulation dynamics, the influence of a single patch on the metapopulation depends on the number of individuals in the patch. Since there is usually no obvious natural upper limit on the number of individuals in a patch, this leads to ...

Coastal fisheries adaptations to increasing climate change exposure in Japan
People and Nature, Volume 6, Issue 6, Page 2339-2356, December 2024.Abstract Climate change‐driven ocean warming is altering the geographic ranges of species, leading to a poleward shift of tropical species into temperate regions (tropicalisation). This threatens the native marine community assemblages by changing the availability of traditional marine resources, thus impacting the livelihood and well‐being of coastal ...

Limiting the spread of disease through altered migration patterns [PDF]
, 2015 We consider a model for an epidemic in a population that occupies geographically distinct locations. The disease is spread within subpopulations by contacts between infective and susceptible individuals, and is spread between subpopulations by the ...

VERTICALLY TRANSMITTED VECTOR-BORNE DISEASES AND THE EFFECTS OF EXTREME TEMPERATURE
, 2017 An existing compartmental model of vector-borne diseases is considered to incorporate vertical transmissions in the vector and the host populations. The effects of extrinsic incubation rate of the disease causing pathogen in mosquitoes on the epidemic as

Veterinary Dermatology, Volume 35, Issue 4, Page 418-431, August 2024.Background – Diagnosis of canine adverse food reactions (AFRs) is based on vague criteria, such as ‘>50% improvement’ during elimination diet trial (EDT) followed by ‘deterioration’ during provocation test (PT). Objective – The objective of the study was to use predefined criteria to evaluate response during EDT [i.e., Owner Global Assessment of ...

Proof of a conjecture of N. Konno for the 1D contact process [PDF]
, 2005 Consider the one-dimensional contact process. About ten years ago, N. Konno stated the conjecture that, for all positive integers $n,m$, the upper invariant measure has the following property: Conditioned on the event that $O$ is infected, the events $\{$
