Psychological Capital and Perceived Stress in Nurses: The Mediating Role of Need for Recovery and Recovery Experiences

Nursing Open, Volume 13, Issue 9, September 2026.
ABSTRACT Aim To examine whether recovery experiences and need for recovery mediate the association between psychological capital and perceived stress in nurses. Design Cross‐sectional online survey. Methods A total of 184 nurses currently practicing in France completed an anonymous online questionnaire administered in January 2023.

h$h$‐Function, Hilbert–Kunz density function and Frobenius–Poincaré function

Journal of the London Mathematical Society, Volume 114, Issue 3, September 2026.
Abstract Given ideals I,J$I,J$ of a noetherian local ring (R,m)$(R, \mathfrak {m})$ such that I+J$I+J$ is m$\mathfrak {m}$‐primary and a finitely generated R$R$‐module M$M$, we associate an invariant of (M,R,I,J)$(M,R,I,J)$ called the h$h$‐function.

New Results on the Computation of Periods of IETs

Mathematics
We introduce a novel technique for computing the periods of (d,k)-IETs based on Rauzy induction R. Specifically, we establish a connection between the set of periods of an interval exchange transformation (IET) T and those of the IET T′ obtained either ...

Simple homotopy theory for Fukaya categories

Journal of Topology, Volume 19, Issue 3, September 2026.
Abstract We develop a categorical framework for simple homotopy theory in Fukaya categories, based on the fundamental group of the ambient symplectic manifold. When the first Chern class vanishes, we show that any isomorphism in the Fukaya category of a Weinstein manifold has trivial Whitehead torsion.

The Two Extremal Rays of Some Hyper–Kähler Fourfolds

Mathematische Nachrichten, Volume 299, Issue 8, Page 2161-2176, August 2026.
ABSTRACT We consider projective Hyper–Kähler manifolds of dimension 4 that are deformation equivalent to Hilbert squares of K3 surfaces. In case such a manifold admits a divisorial contraction, the exceptional divisor is a conic bundle over a K3 surface. A classification of lattice embeddings implies that there are five types of such conic bundles.

Optimization Algorithm for Determining the Source Surface Radius Based on Parker Solar Probe In Situ Measurements From Encounters 1 to 19

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract The Potential Field Source Surface (PFSS) extrapolation is a method for estimating the large scale coronal magnetic field from photospheric magnetograms. The source surface serves as the outer boundary of its solution domain, and is typically a spherical surface.

Mitigating Black Pod Disease in Cocoa Plants: An Optimal Control and Cost‐Effectiveness Analysis

Natural Resource Modeling, Volume 39, Issue 3, August 2026.
ABSTRACT Black pod disease (BPD), caused by Phytophthora species, continues to pose a significant threat to cocoa production, particularly in tropical regions where cocoa farming is a major economic activity. This study develops a deterministic compartmental model to understand the transmission dynamics of BPD and evaluate the impact of multiple ...

An asymmetric rotor model under external, parametric, and mixed excitations: Nonlinear bifurcation, active control, and rub-impact effect

Journal of Low Frequency Noise, Vibration and Active Control
This article explores the nonlinear dynamical analysis and control of a 2 − DOF system that emulates the lateral vibration of an asymmetric rotor model under external, multi-parametric, and mixed excitation.

Impedance Spectroscopy of Bifurcation Oscillations in S‐Type Self‐Oscillatory Devices

Advanced Physics Research, Volume 5, Issue 7, July 2026.
Impedance spectroscopy (IS) reveals stability regimes and bifurcation dynamics in S‐type self‐oscillatory devices. By linking nonlinear control theory with frequency‐domain measurements, experimental signatures of oscillations, entrainment, and phase locking are directly identified.

Real‐Life Effectiveness After Switching to Avalglucosidase Alfa in Late‐Onset Pompe Disease Patients Worsening on Alglucosidase Alfa Therapy: A French Cohort Study

European Journal of Neurology, Volume 33, Issue 7, July 2026.
Illustrating motor function changes before the switch, during the first year, and during the second year after switching treatment. ABSTRACT Late‐onset Pompe disease (LOPD) is a progressive myopathy. Enzyme replacement therapy is effective, but long‐term outcomes vary.
