Physiological Responses to Virtual Reality‐Based Stress Regulation and Relaxation Interventions: A Systematic Review

Stress and Health, Volume 42, Issue 2, April 2026.
ABSTRACT Physiological markers are increasingly used to monitor individuals undergoing Virtual Reality (VR) stress interventions. However, several challenges arise when employing these markers to assess the impact of VR stress interventions. This systematic review synthesises and critically discusses the literature on VR stress interventions across ...

Non‐vanishing of Poincaré series on average

Mathematika, Volume 72, Issue 2, April 2026.
Abstract We study when Poincaré series for congruence subgroups do not vanish identically. We show that almost all Poincaré series with suitable parameters do not vanish when either the weight k$k$ or the index m$m$ varies in a dyadic interval. Crucially, analyzing the problem ‘on average’ over these weights or indices allows us to prove non‐vanishing ...

Hopf's last hope: spatiotemporal chaos in terms of unstable recurrent patterns

, 1996
Spatiotemporally chaotic dynamics of a Kuramoto-Sivashinsky system is described by means of an infinite hierarchy of its unstable spatiotemporally periodic solutions.

Coexistence of algebraic and non-algebraic limit cycles for quintic polynomial differential systems

Electronic Journal of Differential Equations, 2017
In the work by Gine and Grau [11], a planar differential system of degree nine admitting a nested configuration formed by an algebraic and a non-algebraic limit cycles explicitly given was presented.

Exploring new closed-form solitary waves of a nonlinear ionic transport model arising in microtubular mass flow and their global dynamical analysis

Ain Shams Engineering Journal
This work presents a comprehensive analytical and dynamical exploration of a nonlinear ionic currents microtubule model, which governs the propagation of ionic waves and electrical impulses along the cytoskeletal microtubule network.

When DA VINCI Met Wallas: Extended Modeling of the Creative Process

The Journal of Creative Behavior, Volume 60, Issue 1, March 2026.
ABSTRACT By positing the centrality of process‐oriented definitions of creativity, the article revisits Graham Wallas's The Art of Thought, showing that its legacy extends beyond the canonical four‐stage model for the creative process. We first extract from Wallas's book some lesser known details that are proxies of metacognitive and emotional control.

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 ...

A Re‐Examination of Foundational Elements of Cosmology

Fortschritte der Physik, Volume 74, Issue 3, March 2026.
ABSTRACT This paper undertakes a conceptual re‐examination of several foundational elements of cosmology through the lens of spacetime symmetries. A new derivation of the Friedmann–Lemaître–Robertson–Walker metric is obtained by a careful conceptual examination of rotations and translations on generic manifolds, followed by solving the rotational and ...

Monopoles, Clarified

Fortschritte der Physik, Volume 74, Issue 3, March 2026.
ABSTRACT We propose a manifestly duality‐invariant, Lorentz‐invariant, and local action to describe quantum electrodynamics in the presence of magnetic monopoles that derives from Sen's formalism. By employing field strengths as the dynamical variables, rather than potentials, this formalism resolves longstanding ambiguities in prior frameworks.
