Westerly winds prompted an anomalous southward migration of Pacific saury (Cololabis saira)

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract The Pacific saury (Cololabis saira), a key pelagic fish in the Northwest Pacific, exhibits autumn migration modulated by Kuroshio–Oyashio Extension mesoscale features, yet daily fishing ground variability remains unexplained. Traditional reliance on remote sensing data has limited understanding of the three‐dimensional mechanisms governing the

A Thermodynamic Framework for Turing‐Type Instabilities in Porous Media: Part I Theory

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Pattern formation in geological materials is commonly described using analogies to Turing‐type reaction–diffusion systems, yet a unifying thermodynamic explanation remains elusive. Here we develop a multiscale, thermodynamically consistent framework for pattern‐forming instabilities in porous media undergoing coupled thermo–hydro–mechanical ...

Probing chaos in Schwarzschild-de Sitter spacetime: The role of black hole and cosmological horizons

Physics Letters B
In this paper, we study the motion of a massless, chargeless particle in Schwarzschild-de Sitter spacetime, revealing exponential radial growth and potential chaos in an integrable system. Poincaré sections show regular Kolmogorov–Arnold–Moser (KAM) tori

Brownian Motion With Partial Resetting Conditioned to Stay Positive

Bulletin of the London Mathematical Society, Volume 58, Issue 3, March 2026.
Abstract We consider Brownian motion with partial resetting, which has recently attracted a lot of attention in physics as well as the mathematics literature. We analyze the speed of convergence of this process towards stationarity as well as its quasistationary behavior.

Probing thermodynamic phase transitions via Lyapunov exponent in AdS black hole with perfect fluid dark matter

European Physical Journal C: Particles and Fields
We revisit the large-small black hole phase transitions in Reissner–Nordström (RN) AdS black holes coupled with perfect fluid dark matter. Besides the free energy, we examine the features of Lyapunov exponents for both massive and massless particles ...

Modulation of slow and fast oscillations by direct current stimulation in the cerebral cortex in vitro

The Journal of Physiology, Volume 604, Issue 5, Page 2131-2151, 1 March 2026.
Abstract figure legend Direct‐current (DC) electric fields modulate spontaneous slow oscillations in cerebral cortex slices in vitro. Schematic of the in vitro preparation (upper panels). Spontaneous slow oscillations (SO; <1 Hz) consisting of alternating Up (active) and Down (silent) states were observed under control conditions.

Effects of metronome walking on long-term attractor divergence and correlation structure of gait: a validation study in older people

Scientific Reports
This study investigates the effects of metronome walking on gait dynamics in older adults, focusing on long-range correlation structures and long-range attractor divergence (assessed by maximum Lyapunov exponents).
