Microscopic approach to current-driven domain wall dynamics

open access: yes, 2008
This review describes in detail the essential techniques used in microscopic theories on spintronics. We have investigated the domain wall dynamics induced by electric current based on the $s$-$d$ exchange model.

Cell surface interactome analysis identifies TSPAN4 as a negative regulator of PD‐L1 in melanoma

open access: yesMolecular Oncology, EarlyView.
Using cell surface proximity biotinylation, we identified tetraspanin TSPAN4 within the PD‐L1 interactome of melanoma cells. TSPAN4 negatively regulates PD‐L1 expression and lateral mobility by limiting its interaction with CMTM6 and promoting PD‐L1 degradation.

PARP inhibition and pharmacological ascorbate demonstrate synergy in castration‐resistant prostate cancer

open access: yesMolecular Oncology, EarlyView.
Pharmacologic ascorbate (vitamin C) increases ROS, disrupts cellular metabolism, and induces DNA damage in CRPC cells. These effects sensitize tumors to PARP inhibition, producing synergistic growth suppression with olaparib in vitro and significantly delayed tumor progression in vivo. Pyruvate rescue confirms ROS‐dependent activity.

A new approach to the design of time varying control systems with application to the space shuttle booster [PDF]

open access: yes
A general approach toward the analysis and design of closed loop control for slowly time-varying linear systems was investigated. The approach is by the method of generalized multiple scales, in which slow and fast dynamics are systematically separated ...

Solutions of half-linear differential equations in the classes Gamma and Pi [PDF]

open access: yes, 2016
We study asymptotic behavior of (all) positive solutions of the non-oscillatory half-linear differential equation of the form (r(t)|y'|^ {alpha-1} sgn y')'=p(t)|y|^{alpha-1}sgn y, where alpha>1 and r,p are positive continuous functions, with the ...

LDAcoop: Integrating non‐linear population dynamics into the analysis of clonogenic growth in vitro

open access: yesMolecular Oncology, EarlyView.
Limiting dilution assays (LDAs) quantify clonogenic growth by seeding serial dilutions of cells and scoring wells for colony formation. The fraction of negative wells is plotted against cells seeded and analyzed using the non‐linear modeling of LDAcoop.

Equiconvergence of expansions in root functions of a differential operator and in a trigonometric Fourier series

open access: yesСовременная математика: Фундаментальные направления
We consider a non-self-adjoint ordinary differential operator defined on a finite interval by an \( n \)th-order linear differential expression with a nonzero coefficient of the \( (n-1) \)th derivative and two-point Birkhoff regular boundary conditions.

Topological properties of P.A. random graphs with edge-step functions

open access: yes, 2019
In this work we investigate a preferential attachment model whose parameter is a function $f:\mathbb{N}\to[0,1]$ that drives the asymptotic proportion between the numbers of vertices and edges of the graph.

Covariant approach to equilibration in effective field theories

open access: yes, 2001
The equilibration of two coupled reservoirs is studied using a Green function approach which is suitable for future development with the closed time path method.

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity

open access: yesMolecular Oncology, EarlyView.
Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve
