Spectrum of continuous two-contours system [PDF]
ITM Web of Conferences, 2019 A deterministic continuous dynamical system is considered. This system contains two contours. The length of the ith contour equals ci, i = 1, 2. There is a moving segment (cluster) on each contour.

Continuous spectrum of Steklov nonhomogeneous elliptic problem [PDF]
Opuscula Mathematica, 2015 By applying two versions of the mountain pass theorem and Ekeland's variational principle, we prove three different situations of the existence of solutions for the following Steklov problem: \[\begin{aligned}\Delta_{p(x)} u&=|u|^{p(x)-2}u \phantom ...

Cortical Clefts and Cortical Bumps: A Continuous Spectrum [PDF]
Journal of Clinical and Diagnostic Research, 2016 Cortical ‘clefts’ (schizencephaly) and cortical ‘bumps’ (polymicrogyria) are malformations arising due to defects in postmigrational development of neurons.

Non-autonomous Eigenvalue Problems with Variable (p1,p2)-Growth
Advanced Nonlinear Studies, 2017 We are concerned with the study of a class of non-autonomous eigenvalue problems driven by two non-homogeneous differential operators with variable (p1,p2){(p_{1},p_{2})}-growth.

A strategy to quantify myofibroblast activation on a continuous spectrum
Scientific Reports, 2022 Myofibroblasts are a highly secretory and contractile cell phenotype that are predominant in wound healing and fibrotic disease. Traditionally, myofibroblasts are identified by the de novo expression and assembly of alpha-smooth muscle actin stress ...
