Front Propagation Through a Perforated Wall
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT We consider a bistable reaction– diffusion equation ut=Δu+f(u)$u_t=\Delta u +f(u)$ on RN${\mathbb {R}}^N$ in the presence of an obstacle K$K$, which is a wall of infinite span with many holes. More precisely, K$K$ is a closed subset of RN${\mathbb {R}}^N$ with smooth boundary such that its projection onto the x1$x_1$‐axis is bounded and that ...

Nonstandard numerical methods for a class of predator-prey models with predator interference
Electronic Journal of Differential Equations, 2007 We analyze a class of predator-prey models with Beddington-DeAngelis type functional response. The models incorporate the mutual interference between predators, which stabilizes predator-prey interactions even when only a linear intrinsic growth rate of ...

On (g − 2) μ from gauged U(1) X
Journal of High Energy Physics, 2022 We investigate an economical explanation for the (g − 2) μ anomaly with a neutral vector boson from a spontaneously broken U(1) X gauge symmetry. The Standard Model fermion content is minimally extended by 3 right-handed neutrinos.

A guide to neuromodulation in drug‐resistant epilepsy
Epileptic Disorders, EarlyView.Abstract Neuromodulation is approved for the treatment of drug‐resistant epilepsy. It has been increasingly utilized over the past two decades with the approval of deep brain stimulation (DBS) and responsive neurostimulation (RNS) in addition to vagus nerve stimulation (VNS)—particularly in patients who are not deemed to be good resective surgical ...

Nonstandard Foundations of Equilibrium Search Models [PDF]
We develop an equilibrium sequential search model which includes most of the literature as special cases. In particular, the model can accommodate heterogeneity in buyers’ search costs and demand functions and firms’ cost functions, with general demand ...

Epileptic Disorders, EarlyView.Abstract Objective To identify clinically meaningful patterns in ictal electroclinical features of focal epilepsy using a data‐driven, unsupervised learning approach, and to assess whether such patterns can localize and lateralize the epileptogenic zone (EZ) more accurately than conventional electroclinical interpretation.

Time variation of fundamental constants in nonstandard cosmological models [PDF]
, 2021 In this work we have studied the lithium problem in nonstandard cosmological models. In particular, by using the public code ALTERBBN, we have included in the computation of the primordial light nuclei abundances, the effects of the inclusion of dark ...

Epilepsia, EarlyView.Abstract Objective The application of artificial intelligence/machine learning (AI/ML) to magnetic resonance imaging (MRI) promises to enhance and support clinical decision‐making in epilepsy. However, there currently lacks an appropriate assessment of clinical utility and study rigor of current AI/ML‐driven models that are targeted toward supporting ...
