Uniform and strict persistence in monotone skew-product semiflows with applications to non-autonomous Nicholson systems [PDF]
, 2016 Producción CientíficaWe determine sufficient conditions for uniform and strict persistence in the case of skew-product semiflows generated by solutions of non-autonomous families of cooperative systems of ODEs or delay FDEs in terms of the principal ...

A mathematical model of malaria transmission in a periodic environment
Journal of Biological Dynamics, 2018 In this paper, we present a mathematical model of malaria transmission dynamics with age structure for the vector population and a periodic biting rate of female anopheles mosquitoes.

Uniform weak implies uniform strong persistence for non-autonomous semiflows [PDF]
Proceedings of the American Mathematical Society, 1999 It is shown that, under two additional assumptions, uniformly weakly persistent semiflows are also uniformly strongly persistent even if they are non-autonomous. This result is applied to a time-heterogeneous model of S-I-R-S type for the spread of infectious childhood diseases.

ON THE PERSISTENCE OF SPATIAL ANALYTICITY FOR THE BEAM EQUATION [PDF]
, 2022 Persistence of spatial analyticity is studied for solution of the beam equation utt + (m + Δ2) u + |u| p−1u = 0 on Rn × R. In particular, for a class of analytic initial data with a uniform radius of analyticity σ0, we obtain an asymptotic lower bound

Is uniform persistence a robust property in almost periodic models? A well-behaved family: almost periodic Nicholson systems [PDF]
, 2018 Producción CientíficaUsing techniques of non-autonomous dynamical systems, we completely characterize the persistence properties of an almost periodic Nicholson system in terms of some numerically computable exponents.

Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring, 2021 Introduction Understanding of the natural history of apathy and its impact on patient function is limited. This study examines, in a large, national sample of Alzheimer's disease (AD) patients with long follow‐ups: (1) prevalence, incidence, and ...

Uniform persistence and almost periodic solutions of a nonautonomous patch occupancy model
Advances in Difference Equations, 2020 In this paper, a nonlinear nonautonomous model in a rocky intertidal community is studied. The model is composed of two species in a rocky intertidal community and describes a patch occupancy with global dispersal of propagules and occupy each other by ...
