Boundary behavior of solutions to fractional p-Laplacian equation

In this work, a generalized Hopf’s lemma and a global boundary Harnack inequality are proved for solutions to fractional p-Laplacian equations. Then the isolation of the first   (s,p)  -eigenvalue is shown in bounded open sets satisfying the Wiener ...

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

FEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Modeling with fractional difference equations

, 2010
In this paper, we develop some basics of discrete fractional calculus such as Leibniz rule and summation by parts formula. We define simplest discrete fractional calculus of variations problem and derive Euler–Lagrange equation.

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

FEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death

FEBS Open Bio, EarlyView.
Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...

Fractional-order super-twisting sliding mode active disturbance rejection control for electro-hydraulic position servo systems

Nonlinear Engineering
To address the inherent nonlinearity, time-varying dynamics, and disturbance susceptibility of electro-hydraulic position servo systems in high-precision applications like aerospace actuators, this article proposes a fractional-order super-twisting ...
