Deciphering pro‐arrhythmogenic mechanisms of EPAC in human atrial cardiomyocytes

The Journal of Physiology, EarlyView.
Abstract figure legend This study aimed to investigate the effect of exchange proteins directly activated by cAMP (EPAC) on the regulation of human atrial cardiomyocyte electrophysiology and their potential involvement in the onset of atrial fibrillation (AF).

α‐Synuclein oligomers slow down action potential firing and enhance dopamine release by increasing Cav2.2 currents in midbrain dopaminergic neurons

The Journal of Physiology, EarlyView.
Abstract figure legend Left: the spontaneous quantal release of dopamine (DA) occurs at very low frequency in control conditions. Right: exogenous α‐synuclein potentiates Cav2.2 currents and DA release but drastically reduces the spontaneous firing rate of substantia nigra DA neurons.

Pharmacological manipulation of the immediate effects of spinal trauma in neonatal rats reveals a crucial role for TRPV4 receptors

The Journal of Physiology, EarlyView.
Abstract figure legend A, schematic illustration of the ventral aspect of an ex vivo preparation of the entire CNS from a neonatal rat subjected to a calibrated thoracic impact. The trauma induced a large depolarising injury potential (DIP, black trace) recorded from the L5 ventral root (VRrL5), which was markedly reduced by transient receptor ...

Functional inequalities involving Bessel and modified Bessel functions of the first kind

Expositiones Mathematicae, 2008
Since the sine and cosine functions and the hyperbolic sine and cosine functions are particular cases of Bessel and modifed Bessel functions, the author extends the inequality \(\cosh x-1\), where \(\Gamma\) is Euler gamma function and \(I_{p}(x)\) is the modified Bessel function of first kind. Some properties and inequalities satisfied by \(G_{p}(x)\)

GloMarGridding: A Python Toolkit for Flexible Spatial Interpolation in Climate Applications

Geoscience Data Journal, Volume 13, Issue 2, April 2026.
Global surface climate datasets contain structural uncertainty that is difficult to attribute to individual processing steps. We present GloMarGridding, a Python package that isolates the spatial interpolation component using Gaussian Process Regression (or kriging) to generate spatially complete fields and uncertainty estimates. The techniques used in

Special Relativity via Modified Bessel Functions

Zeitschrift für Naturforschung A, 2000
The recursive formulas of modified Bessel functions give the relativistic expressions for energy and momentum. Modified Bessel functions are solutions to a continuous time, one-dimensional discrete jump process. The jump process is analyzed from two inertial frames with a relative constant velocity; the average distance of a particle along the chain ...

Internal Lee Waves Control Deep Ocean Turbulent Mixing in the Antarctic Circumpolar Current at 50°E

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Full‐depth (Surface‐to‐bottom) turbulent kinetic energy dissipation (TKED) observed with fast‐response thermistors across the Antarctic Circumpolar Current (ACC) at 50° $\mathit{{}^{\circ}}$E is compared with the energy flux of bottom‐generated internal waves estimated with high‐resolution multibeam bathymetry.

GeAl2‐2xFe2xO3(OH)4 Nanotubes: New Electrocatalyst for Oxygen Evolution Reaction

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
Fe‐doped imogolite nanotubes are synthesized via a one‐step hydrothermal method with varying Fe substitution ratios x. Structural and spectroscopic analyses confirm homogeneous Fe incorporation while preserving tubular shape. Optimal doping at x = 0.05 enhances optical absorption, narrows band gap, reduces charge transfer resistance, and significantly ...

Spatiotemporal Plasma–Mediated Laser Fabrication of Ultrahigh‐Aspect‐Ratio Nanochannel Arrays for Vertical Perovskite Nanowire Semiconductor Devices

Advanced Functional Materials, Volume 36, Issue 23, 19 March 2026.
A spatiotemporal plasma–mediated laser processing approach is developed to fabricate ultrahigh–aspect ratio nanochannel arrays and corresponding perovskite nanowire arrays within transparent materials for optoelectronics devices. The laser‐fabricated nanochannels serve as templates for controlled perovskite infiltration and crystallization, enabling ...
