Inferring community assembly processes from mangrove species–area relationships
Oikos, EarlyView.The increasing species–area relationship (SAR) is a nearly universal ecological law. But recent theory has predicted that in systems with low large‐scale diversity the law should be violated and the SAR should be nearly flat at intermediate scales, with species richness roughly constant at some value typically greater than one.

Flow Memory Effect on Open‐Frame Remotely Operated Vehicle Motion
Journal of Field Robotics, EarlyView.ABSTRACT The flow memory effect is a kind of viscous force caused by acceleration between continuous phases and underwater vehicles and the development of the boundary layer near the interfacial surface. This paper establishes a 6‐degrees‐of‐freedom unsteady equation of motion describing the flow memory effect on viscous hydrodynamic loads.

Predicting solutions of the Lotka‐Volterra equation using hybrid deep network
Theoretical and Applied Mechanics Letters, 2022 Prediction of Lotka-Volterra equations has always been a complex problem due to their dynamic properties. In this paper, we present an algorithm for predicting the Lotka-Volterra equation and investigate the prediction for both the original system and ...

A note on the qualitative analysis of Volterra integro-differential equations
Journal of Taibah University for Science, 2019 The aim of paper is to analyse some qualitative properties of solutions of nonlinear Volterra integro-differential equations (VIDDEs) with constant delay and Volterra integro-differential equations (VIDEs) without delay by means of the Razumikhin method.

EEMtoolbox: A user‐friendly R package for flexible ensemble ecosystem modelling
Methods in Ecology and Evolution, EarlyView.Abstract Forecasting ecosystem changes due to disturbances or conservation interventions is essential to improve ecosystem management and anticipate unintended consequences of conservation decisions. Mathematical models allow practitioners to understand the potential effects and unintended consequences via simulation.

On the absence of Volterra correct restrictions and extensions of the Laplace operator [PDF]
arXiv, 2016 At the beginning of the last century J. Hadamard constructed the well-known example illustrating the incorrectness of the Cauchy problem for elliptic-type equations. If the Cauchy problem for some differential equation is correct, then it is usually a Volterra problem, i.e., the inverse operator is a Volterra operator. At present, not a single Volterra

Stochastic Volterra equations with Hölder diffusion coefficients [PDF]
Stoch. Process. Appl., vol. 161, p. 291--315, 2023, 2022 The existence of strong solutions and pathwise uniqueness are established for one-dimensional stochastic Volterra equations with locally H{\"o}lder continuous diffusion coefficients and sufficiently regular kernels. Moreover, we study the sample path regularity, the integrability and the semimartingale property of solutions to one-dimensional ...
