Structured populations with distributed recruitment: from PDE to delay formulation
, 2016 In this work first we consider a physiologically structured population model with a distributed recruitment process. That is, our model allows newly recruited individuals to enter the population at all possible individual states, in principle.

Bivariate second--order linear partial differential equations and orthogonal polynomial solutions [PDF]
, 2011 In this paper we construct the main algebraic and differential properties and the weight functions of orthogonal polynomial solutions of bivariate second--order linear partial differential equations, which are admissible potentially self--adjoint and of ...

Gravitating fluids with Lie symmetries
, 2010 We analyse the underlying nonlinear partial differential equation which arises in the study of gravitating flat fluid plates of embedding class one. Our interest in this equation lies in discussing new solutions that can be found by means of Lie point ...

Известия высших учебных заведений. Поволжский регион: Физико-математические науки, 2020 Background. The problem of evaluation of the special (singular) solutions of Clairaut-type partial differential equations attracts a lot of interest studying various transformations of nonlinear equations of mathematical physics, for example, Legendre

Population Ecology, EarlyView.In the process of captive breeding and reintroduction of endangered animal species, it is crucial to minimize familial bias in reproductive success during the reintroduction phase to preserve genetic diversity. In this study, we attempted to identify the familial lineage of individuals of the endangered bagrid fish Tachysurus ichikawai born at the ...

On nonlinear Feynman-Kac formulas for viscosity solutions of semilinear parabolic partial differential equations with gradient-dependent nonlinearities [PDF]
arXiv, 2023 The classical Feynman-Kac identity represents solutions of linear partial differential equations in terms of stochastic differential euqations. This representation has been generalized to nonlinear partial differential equations on the one hand via backward stochastic differential equations and on the other hand via stochastic fixed-point equations.

A partial differential equation for pseudocontact shift
, 2014 It is demonstrated that pseudocontact shift (PCS), viewed as a scalar or a tensor field in three dimensions, obeys an elliptic partial differential equation with a source term that depends on the Hessian of the unpaired electron probability density.

Evaluating the origin and spread of spotted lanternfly (Lycorma delicatula) in Japan
Population Ecology, EarlyView.The invasive spotted lanternfly (Lycorma delicatula) is native to China and is a serious economic pest in the Republic of Korea and the United States, though it is not considered a pest in Japan. We established a distribution map of L. delicatula in Japan through a comprehensive review of published literature and citizen science reports and analyzed ...
