Existence and uniqueness of positive solutions for Kirchhoff type beam equations
Electronic Journal of Qualitative Theory of Differential Equations, 2020 This paper is concerned with the existence and uniqueness of positive solutions for the fourth order Kirchhoff type problem \begin{equation*} \begin{cases} u''''(x)-\Big(a+b\int_0^1(u'(x))^2dx\Big)u''(x)=\lambda f(u(x)),& x\in(0,1),\\ u(0)=u(1)=u''(0)=u''

Multiple solutions for a Schrödinger-Bopp-Podolsky system with positive potentials [PDF]
arXiv, 2020 In the paper we prove existence of solutions for a Schr\"odinger-Bopp-Podolsky system under positive potentials. We use the Ljusternick-Schnirelmann and Morse Theories to get multiple solutions with a priori given ``interaction energy''.

Identification of novel small molecule inhibitors of ETS transcription factors
FEBS Letters, EarlyView.ETS transcription factors play an essential role in tumourigenesis and are indispensable for sprouting angiogenesis, a hallmark of cancer, which fuels tumour expansion and dissemination. Thus, targeting ETS transcription factor function could represent an effective, multifaceted strategy to block tumour growth. The evolutionarily conserved E‐Twenty‐Six

Singular solutions of fully nonlinear elliptic equations and applications [PDF]
, 2011 We study the properties of solutions of fully nonlinear, positively homogeneous elliptic equations near boundary points of Lipschitz domains at which the solution may be singular. We show that these equations have two positive solutions in each cone of $\mathbb{R}^n$, and the solutions are unique in an appropriate sense.

Evolution equations with eventually positive solutions [PDF]
arXiv, 2022 We discuss linear autonomous evolution equations on function spaces which have the property that a positive initial value leads to a solution which initially changes sign, but then becomes - and stays - positive again for sufficiently large times. This eventual positivity phenomenon has recently been discovered for various classes of differential ...

FEBS Letters, EarlyView.In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Positive solutions for a nonlocal problem with singularity
Electronic Journal of Differential Equations, 2017 In this article we study a nonlocal problem involving singular nonlinearity. Based on the variational and perturbation methods, we obtain the existence of two positive solutions for this problem.
