Existence of solutions for p(x)-Kirchhoff type problems with non-smooth potentials
Electronic Journal of Differential Equations, 2015 We consider a class of p(x)-Kirchhoff type problem with a subdifferential term and a discontinuous perturbation. Assuming the existence of an ordered pair of appropriately defined upper and lower solutions, by the method of lower-upper solutions ...

The Method of Upper, Lower Solutions and Volterra Integral Equations
, 1980 In employing the method of upper and lower solutions to dynamical systems, one is required to impose a certain monotone property on the given system [5,6,11] When the given system does not possess such a monotonic property, stronger forms of upper and ...

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer
Molecular Oncology, EarlyView.Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

Molecular Oncology, EarlyView.Drug resistance limits treatment success in a subset of lung cancers driven by ROS1 gene alterations. Using patient‐derived cells and computer simulations, we studied three key mutations and how they affect five targeted drugs. The mutations reduced drug effectiveness in different ways by altering protein structure and behavior.

Lower and Upper Solutions for Singular Derivative Dependent Dirichlet Problem [PDF]
Mathematical Inequalities & Applications, 2001 The author develops the lower and upper solution method to work out the Dirichlet problem \[ u''+f(t,u,u')=0,\quad u(a)=0,\;u(b)=0, \] where \(f\) can be singular for \(t=a\), \(t=b\) and \(u=0\). Solutions are supposed to be in \(W^{1,1}(a,b)\cap W^{2,1}_{loc}(a,b)\).

Geomorphic response to neotectonic activity in the Jura Mountains and in the southern Upper Rhine Graben [PDF]
, 2008 Present-day tectonic activity at the southern end of the Upper Rhine Graben in central Western Europe is evidenced by significant seismicity, which has been documented over hundreds of years.

Molecular Oncology, EarlyView.BCL9 and BCL9L drive bladder cancer progression by enhancing β‐catenin signaling, promoting proliferation, migration, invasion, and organoid growth. Genetic depletion of BCL9(L) suppresses malignant phenotypes, while pharmacological disruption of the β‐catenin/BCL9(L) complex with ZW4864 inhibits canonical Wnt signaling and tumor‐associated cellular ...

Upper and lower bounds of solutions for fractional integral equations [PDF]
Surveys in Mathematics and its Applications, 2007 n this paper we consider the integral equation of fractional order in sense of Riemann-Liouville operator um(t) = a(t) Iα [b(t)u(t)]+f(t) with m ≥ 1, t ∈ [0, T], T < ∞ and 0< α
