Modeling and Analysis of Nonlinear Radiative and Electromagnetic Effects With Second‐Order Slip in Unsteady Hybrid Nanofluid Flow Past a Porous Stretching Surface

Engineering Reports, Volume 8, Issue 8, August 2026.
The current work examines the dynamics of the stagnation point flow of an unsteady hybrid nanofluid (Fe2O3–Cu/H2O) across an inclined porous stretching surface. It considers heat transfer, second‐order slip, electrical field, heat source/sink, mixed convection, and magnetic field effects, as well as linear and nonlinear radiation.

Protein kinase Cδ and pharmacomechanical coupling: Re‐envisioning cerebral vascular control

The Journal of Physiology, Volume 604, Issue 15, Page 6324-6347, 1 August 2026.
Abstract figure legend Top, G‐protein coupled receptors trigger electromechanical and pharmacomechanical coupling, the latter via signal transduction pathways that inhibit myosin light chain phosphatase. Middle, the relative contribution of electromechanical and pharmacomechanical coupling varies with the concentration and the vessel area to which ...

Effects of Pore Fluid Properties on Dynamic Slip in Sandstone‐Derived Fault Gouges From the Groningen Gas Reservoir

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract The dynamic slip behavior of faults is strongly influenced by the thermal and hydraulic properties of pore fluids, which control thermal pressurization (TP) during seismic slip. While previous experiments showed significant TP‐induced weakening in DI‐water‐saturated Groningen sandstone gouges, in situ fluids are brine or brine–gas mixtures ...
