A mathematical model of the multiple sclerosis plaque [PDF]
Journal of Theoretical Biology, 2021 Multiple sclerosis is an autoimmune disease that affects white matter in the central nervous system. It is one of the primary causes of neurological disability among young people. Its characteristic pathological lesion is called a plaque, a zone of inflammatory activity and tissue destruction that expands radially outward by destroying the myelin and ...

The mathematics of multiple lockdowns [PDF]
Scientific Reports, 2021 AbstractWhile vaccination is the optimal response to an epidemic, recent events have obliged us to explore new strategies for containing worldwide epidemics, like lockdown strategies, where the contacts among the population are strongly reduced in order to slow down the propagation of the infection.

A MATHEMATICAL REVIEW ON THE MULTIPLE-SOLUTION PROBLEM [PDF]
International Journal of Modern Physics A, 2011 The recent multiple-solution problem in extracting physics information from a fit to the experimental data in high energy physics is reviewed from a mathematical viewpoint. All these multiple solutions were previously found via a fit process, while in this paper we prove that if the sum of two coherent Breit–Wigner functions is used to fit the ...

Journal of Mathematics and Physics, 2021 : In the present work we obtain the existence and multiplicity of nontrivial solutions for the Choquard logarithmic equation (−∆)pu+ |u| u+(ln | · |∗|u|)|u|u = f(u) in R , where N = sp, s ∈ (0, 1), p > 2, a > 0, λ > 0 and f : R → R a continuous ...

Frontiers in Education, 2023 The environment, science, technology, engineering, arts, and mathematics fields (a collection of fields we call E-STEAM) continue to grow and remain economically and ecologically important. However, historically excluded groups remain underrepresented in

PLoS Computational Biology, 2022 We introduce a novel, biologically plausible local learning rule that provably increases the robustness of neural dynamics to noise in nonlinear recurrent neural networks with homogeneous nonlinearities. Our learning rule achieves higher noise robustness

Multiplicity‐1 minmax minimal hypersurfaces in manifolds with positive Ricci curvature [PDF]
Communications on Pure and Applied Mathematics, 2020 We address the one‐parameter minmax construction for the Allen–Cahn energy that has recently lead to a new proof of the existence of a closed minimal hypersurface in an arbitrary compact Riemannian manifold Nn+1$N^{n+1}$ with n≥2$n\ge 2$ (Guaraco's work,

On the Multiplicity One Conjecture in min-max theory [PDF]
Annals of Mathematics, 2019 We prove that in a closed manifold of dimension between 3 and 7 with a bumpy metric, the min-max minimal hypersurfaces associated with the volume spectrum introduced by Gromov, Guth, Marques-Neves, are two-sided and have multiplicity one. This confirms a

Memorizing Schröder’s Method as an Efficient Strategy for Estimating Roots of Unknown Multiplicity
Mathematics, 2021 In this paper, we propose, to the best of our knowledge, the first iterative scheme with memory for finding roots whose multiplicity is unknown existing in the literature.
