Electrodiffusion in cardiac intercalated disc nanostructures alters cell–cell action potential transmission via ephaptic coupling: A model study

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Ephaptic phenomena in a high‐resolution model of the cardiac intercalated disc. Meshed representation of a tortuous intercalated disc that was generated based on electron and super‐resolution microscopy data. Na+ channels (red) and gap junctions (green) are heterogeneously distributed, with additional regions of reduced ion ...

Low‐threshold cutaneous mechanoreceptors on the foot sole have enhanced sensitivity when skin temperature is elevated

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic illustration of microneurography recordings used to examine the effects of local skin heating on cutaneous mechanoreceptor responses in the human foot (left panel). A microelectrode inserted into a peripheral nerve records single‐unit activity from tactile afferent fibres while controlled mechanical stimuli are applied ...

Hydrogen Storage Properties of Vanadium‐Decorated Holey Graphyne: A Density Functional Theory Study

open access: yesEnergy Storage, Volume 8, Issue 5, August 2026.
A V‐decorated HGY exhibits strong yet reversible H2 adsorption, delivering a hydrogen storage capacity of 6.43 wt% with an adsorption energy of −0.46 eV and a desorption temperature of 378 K. ABSTRACT Hydrogen storage remains a key challenge for the practical deployment of hydrogen‐based energy systems due to the limited storage capacity and weak ...

Numerical Investigation of a Diffusive SIR Model: Focus on Positivity Preservation

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 11, Page 11775-11793, 30 July 2026.
ABSTRACT In this paper, we consider a system of semilinear partial differential equations (PDEs) representing a spatially extended SIR epidemic model. A brief analytical investigation of the well‐posedness and positivity of the solutions is provided in the appendix, while the main focus is on the numerical treatment of the model.

Revealing the Hidden Stress Field and Its Thermal Input Dependence in Femtosecond Laser–Processed Silicon Photonic Chip Substrates via Weak Measurement

open access: yesNanophotonics, Volume 15, Issue 13, 13 July 2026.
A novel noncontact method based on weak value amplification enables high‐sensitivity stress mapping of femtosecond laser processed silicon photonic chip substrates. It converts microscale stress into the birefringent phase via the photoelastic effect and reads it out with weak measurement, achieving a 0.37‐kPa detection limit.
