FEBS Letters, EarlyView.Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Multiple boundary peak solutions for some singularly perturbed Neumann problems [PDF]
, 2000 We consider the problem \left \{ \begin{array}{rcl} \varepsilon^2 \Delta u - u + f(u) = 0 & \mbox{ in }& \ \Omega\\ u > 0 \ \mbox{ in} \ \Omega, \ \frac{\partial u}{\partial \nu} = 0 & \mbox{ on }& \ \partial\Omega, \end{array} \right. where \

Existence of solutions for Hardy-Sobolev-Maz'ya systems
Electronic Journal of Differential Equations, 2012 The main goal of this article is to investigate the existence of solutions for the Hardy-Sobolev-Maz'ya system $$displaylines{ -Delta u-lambda frac{u}{|y|^2}=frac{|v|^{p_t-1}}{|y|^t}v,quad hbox{in }Omega,cr -Delta v-lambda frac{v}{|y|^2}=frac{|u ...

Existence of Solutions for Linear Moment Problems [PDF]
Journal of Systemics, Cybernetics and Informatics, 2007 The Cimmino algorithm is an iterative projection method for finding almost common points of measur- able families of closed convex sets in a Hilbert space.

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Meinong and Husserl on Existence. Two Solutions of the Paradox of Non-Existence
Philosophia Scientiæ, 2014 This paper analyzes and compares the attempts at solving the paradox of non-existence put forward by Alexius Meinong and Edmund Husserl. It will be argued that Meinong's solution is not convincing since he retreats from the field of predicate logic, in ...

A Technique for Proving Existence of Solutions
Journal of Mathematical Analysis and Applications, 1997 Problems of the form \[ x'(t)= f(t,x(t)),\qquad t\in[0,T], \quad x(0)\neq x_0,\tag{IVP} \] where \(T\in \mathbb{R}^+\), \(x_0\in \mathbb{R}^N\), and \(f:\mathbb{R}\times \mathbb{R}^N\to \mathbb{R}^N\) are considered and the existence of Carathéodory solutions of (IVP) is studied.

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Positive solutions of a boundary value problem with integral boundary conditions [PDF]
, 2011 We consider boundary-value problems studied in a recent paper. We show that some existing theory developed by Webb and Infante applies to this problem and we use the known theory to show how to find improved estimates on parameters μ*, λ so ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9
FEBS Letters, EarlyView.Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...
