Intercalated disk structure, tissue heterogeneity and ion channel distribution modulate conduction and local calcium influx

The Journal of Physiology, EarlyView.
Abstract figure legend A, three‐dimensional representation of cardiac intercalated disk, reduced to a 100‐partition, computationally efficient network representation. B, ion dynamics within intercalated disk extracellular cleft space. C, rapid pacing leads to localized conduction block in tissue with regions of perturbed intercalated disk (ID ...

Quantifying Nighttime Gravity Wave‐Driven Mesosphere‐Ionosphere Coupling Over CONUS Using NASA AWE Radiance and GNSS TEC Observations

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract We present the first coordinated study of nighttime mesosphere‐ionosphere coupling over the continental United States (CONUS) from January through November 2024 using NASA Atmospheric Waves Experiment (AWE) airglow measurements near 87 km and GNSS Total Electron Content observations near 300 km.

IV. On the theory of electrodynamics [PDF]

Proceedings of the Royal Society of London, 1891
Abstract The electrical ideas of Clerk Maxwell, which were cultivated partly in relation to mechanical models of electrodynamic action, led him to the general principle that electrical currents always flow round complete circuits.

Integration of hBN Single‐Photon Emitters Into a Hybrid Optomechanical Membrane‐In‐The‐Middle Fiber‐Cavity

Nanophotonics, Volume 15, Issue 19, 13 October 2026.
Deterministic manipulation of hexagonal boron nitride (hBN) flakes enables single‐photon emitters (SPEs) to be integrated into a fiber‐based Fabry–Pérot membrane‐in‐the‐middle cavity. Cavity coupling enhances and spectrally funnels the broadband emitter fluorescence, while allowing access to mechanical membrane modes for future hybrid optomechanical ...

Operando Tracking of Oxygen‐Vacancy Dynamics and Negative Capacitance in Ca‐Doped BiFeO3

Advanced Functional Materials, Volume 36, Issue 81, 8 October 2026.
Operando electrochemical impedance spectroscopy, combined with electrocoloration, enables a direct correlation between real‐space ionic redistribution and the corresponding frequency‐domain electrical response. In lateral Ca‐doped BiFeO3 devices, time‐resolved impedance snapshots capture the evolution from bulk‐dominated mixed conduction to an ...

Engineering a Correlated Narrow‐Gap Semiconductor: Effects of Ga Substitution in EuZn2P2

Advanced Electronic Materials, Volume 12, Issue 19, 12 October 2026.
ABSTRACT The effect of Ga substitution on the electronic, magnetic, and low‐energy responses of the Zintl phase EuZn2P2${\rm EuZn}_2 {\rm P}_2$ is investigated by electrical transport, electron spin resonance (ESR), and terahertz time‐domain spectroscopy (THz‐TDS). Incorporating Ga into EuZn2P2${\rm EuZn}_2 {\rm P}_2$ (EuZn1.8Ga0.2P2${\rm EuZn}_{1.8} {\
