, 2010 We consider a nonlinear Neumann problem driven by the p- Laplacian, with a right-hand side nonlinearity which is concave near the origin. Using variational techniques, combined with the method of upper-lower solutions and with Morse theory, we show ...

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Critical Threshold and Stability of Cluster Solutions for Large Reaction-Diffusion Systems in R
, 2002 We study a large reaction-diffusion system which arises in the modeling of catalytic networks and describes the emerging of cluster states. We construct single cluster solutions on the real line and then establish their stability or instability in

Multiple solutions for a discrete anisotropic (p_1(k),p_2(k))-Laplacian equations
Electronic Journal of Differential Equations, 2015 This article concerns the existence and multiplicity solutions for a discrete Dirichlet Laplacian problems. Our technical approach is based on variational methods.

ON THE MULTIPLICITY OF PERIODIC SOLUTIONS OF AN HAMILTONIAN SYSTEM
Demonstratio Mathematica, 2002 By using a variational method based on a generalized saddle point theorem, the author proves the existence of multiple periodic solutions of nonautonomous Hamiltonian systems with bounded gradient of the type \(J\dot x+H'(t,x)+e(t)=0\), where \(H\in C(\mathbb{R}\times\mathbb{R}^{2N},\mathbb{R})\) is periodic in \(t,x\) and continuously differentiable ...

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

MULTIPLE OPTIMAL SOLUTIONS IN QUADRATIC PROGRAMMING MODELS
The problem of determining whether quadratic programming models possess either unique or multiple optimal solutions is important for empirical analyses which use a mathematical programming framework.
