A mathematical model of the multiple sclerosis plaque [PDF]

open access: yesJournal 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]

open access: yesScientific 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.

Fuzzy model of transport demand [PDF]

open access: yesE3S Web of Conferences, 2023
The development of transport networks is costly and cannot solve all transport problems. In this regard, scientifically based planning of the development of the transport complex acquires an important role to improve the quality of the functioning of the

A periodic-like table of space groups

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2023
There are about 100 chemical elements, and 200 space groups, rounding to the nearest hundreds. The elements, by virtue of the iconic periodic table, which hangs in schoolrooms worldwide, are part of our common culture.

A MATHEMATICAL REVIEW ON THE MULTIPLE-SOLUTION PROBLEM [PDF]

open access: yesInternational 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 ...

Synaptic balancing: A biologically plausible local learning rule that provably increases neural network noise robustness without sacrificing task performance.

open access: yesPLoS 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

Eco-digital storytelling: Engaging historically excluded populations in environmental action through mentoring, geospatial technology, and digital media storytelling

open access: yesFrontiers 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
