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

open access: yesFEBS 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.

Hydroxychloroquine Associated With Lower Glomerular Filtration Rate Decline in Lupus Nephritis

open access: yesArthritis Care &Research, EarlyView.
Objective Hydroxychloroquine (HCQ) protects kidney function in lupus nephritis (LN) by preventing flares, yet some cohort studies show no significant benefit in kidney function with HCQ. Clarifying these conflicting findings by showing early and long‐term benefits of HCQ on kidney function preservation is critical.

Delays in Open String Field Theory [PDF]

open access: yes, 2010
We study the dynamics of light-like tachyon condensation in a linear dilaton background using level-truncated open string field theory. The equations of motion are found to be delay differential equations.

Persistent spin currents in an elastic Landau system

open access: yes, 2013
We consider a neutral particle with permanent magnetic dipole moment in an elastic medium with the presence of a uniform distribution of screw dislocations interacting with a radial electric field.

Asymmetric evolution of magnetic reconnection in collisionless accretion disk

open access: yes, 2014
An evolution of a magnetic reconnection in a collisionless accretion disk is investigated using a 2.5 dimensional hybrid code simulation. In astrophysical disks, magnetorotational instability (MRI) is considered to play an important role by generating ...

Stability of an MHD shear flow with a piecewise linear velocity profile [PDF]

open access: yes, 2006
In this paper we present the results of the stability analysis of a simple shear flow of an incompressible fluid with a piecewise linear velocity profile in the presence of a magnetic field.

Ab Initio Study on 3D Anisotropic Ferroelectric Switching Mechanism and Coercive Field in HfO2 and ZrO2

open access: yesAdvanced Functional Materials, EarlyView.
This study uncovers a new switching mechanism in HfO2 and ZrO2, where the absence of a non‐polar layer along the a‐direction induces interaction between polar layers. Consequently, the switching barriers for growth are lower than those for nucleation in this direction, leading to a size‐dependent coercive field that matches experimental observations ...

Oscillatory properties of fourth-order neutral differential equations using new monotonic properties

open access: yesMiskolc Mathematical Notes
The authors investigate the asymptotic behavior of solutions of the fourth-order half-linear neutral differential equation (α(t) ((μ(t)+d(t)μ(a(t)))‴)b)′+m(t)μb(δ(t))=0(e)α′(t ...
