We study a class of individual-based, fixed-population size epidemic models under general assumptions, e.g., heterogeneous contact rates encapsulating changes in behavior and/or enforcement control measures. show that the large-population dynamics are deterministic and relate to Kermack–McKendrick PDE. Our assumptions minimalistic sense only important requirement is basic reproduction number R0...

abstract: in the present paper, we give a necessary and sufficient condition for contact cr-warped product to be contact cr-product in kenmotsu space forms.

Research has proposed different models of how contact situations should be structured to maximize effects, focusing in particular on the role categorization during contact. We conducted two experimental field interventions ( Ns = 247 and 247) test that integrate levels categorization. Each tested was contrasted against a no-intervention control condition. In both studies, we assessed effects sh...

Abstract We aim to enhance the stability of finite element models dynamic structural contact with multiphase granular soils which are described by advanced soil plasticity that can simulate monotonic and cyclic behaviour soils. Often, numerical oscillations cannot be avoided in these cause significantly overshoot stress, leading unrealistic discontinuities stress paths. This situation challenge...
