Hands‐on protocol for preparing water‐soluble fractions from agri‐food samples for NMR‐based metabolomics analysis

FEBS Open Bio, EarlyView.
This research protocol outlines a workflow for nuclear magnetic resonance (NMR)‐based metabolomics in the agri‐food sector. Using two case studies—strawberry leaves (solid matrix) and wine (liquid matrix)—it details the procedures for sample preparation, data acquisition, and processing.

Nuclear pore links Fob1‐dependent rDNA damage relocation to lifespan control

FEBS Open Bio, EarlyView.
Damaged rDNA accumulates at a specific perinuclear interface that couples nucleolar escape with nuclear envelope association. Nuclear pores at this site help inhibit Fob1‐induced rDNA instability. This spatial organization of damage handling supports a functional link between nuclear architecture, rDNA stability, and replicative lifespan in yeast.

Hypergeometric continuation of divergent perturbation series: I. Critical exponents of the Bose–Hubbard model

New Journal of Physics, 2017
We study the connection between the exponent of the order parameter of the Mott insulator-to-superfluid transition occurring in the two-dimensional Bose–Hubbard model, and the divergence exponents of its one- and two-particle correlation functions.

Critical exponent and discontinuous nonlinearities

Differential and Integral Equations, 1993
We prove existence of a positive solution to the problem \[ -\Delta u=| u|^{2^*- 2} u+bh (u-a), \quad u(x)>0 \;\;\text{in }\Omega, \quad u(x)=0\;\;\text{on } \partial\Omega, \tag{1} \] where \(\Omega\) is a bounded regular open set \(\subset \mathbb{R}^ N\), \(2^*= {{2N} \over {n-2}}\) is the critical Sobolev exponent, \(h\) is the Heaviside function ...

The Impact of Tilburg Frailty on Poststroke Fatigue in First‐Ever Stroke Patients: A Cross‐Sectional Study With Unified Measurement Tools and Improved Statistics

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Poststroke fatigue (PSF) and frailty share substantial overlap in their manifestations, yet previous research has yielded conflicting results due to the use of heterogeneous frailty assessment tools. Objective To evaluate the independent impact of frailty on PSF using a unified measurement system (Tilburg Frailty Indicator, TFI ...

Magnetic critical behavior of van der Waals Fe3GaTe2 with above-room-temperature ferromagnetism

APL Materials
Fe3GaTe2 is a promising van der Waals material for future spintronic applications because of its intrinsic above-room-temperature ferromagnetism. Herein, high quality Fe3GaTe2 single crystals were successfully grown by the chemical vapor transport method.

Existence of solutions for critical systems with variable exponents

Mathematical Modelling and Analysis, 2018
In this work, we deal with elliptic systems under critical growth conditions on the nonlinearities. Using a variant of concentration-compactness principle, we prove an existence result.

Schrödinger equation with critical Sobolev exponent

Differential and Integral Equations, 2004
In this paper we study the existence of solutions and their concentration phenomena of a singularly perturbed semilinear Schrodinger equation with the presence of the critical Sobolev exponent.

Applying an Ethical Lens to the Treatment of People With Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT The practice of neurology requires an understanding of clinical ethics for decision‐making. In multiple sclerosis (MS) care, there are a wide range of ethical considerations that may arise. These involve shared decision‐making around selection of a disease‐modifying therapy (DMT), risks and benefits of well‐studied medications in comparison to

Anisotropic critical behavior of current-driven skyrmion dynamics in chiral magnets with disorder

New Journal of Physics, 2020
The dynamic pinning effects are significant in manipulating skymions in chiral magnetic materials with quenched disorder. Through numerical simulations of the non-stationary current-driven dynamics of skyrmions with the Landau–Lifshitz–Gilbert equation ...
