Unsteady Magnetohydrodynamics Heat‐Generating Oldroyd‐B Nanofluid Flow in a Stretching Power Generator Duct Using the Crank–Nicolson Method

open access: yesEngineering Reports, Volume 8, Issue 8, August 2026.
This study explores how a heat‐generating Oldroyd‐B nanofluid behaves inside an annular hydromagnetic power‐generator duct with a porous, axially stretching inner cylinder. The coupled flow, heat, mass, and magnetic‐field equations are solved using the Crank–Nicolson method.

Semi‐Analytical Solution of Time‐Harmonic Soil–Pile Interaction Using Love Numbers in Transversely Isotropic and Layered Half‐Spaces

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 11, Page 4691-4705, 10 August 2026.
ABSTRACT An efficient semi‐analytical approach based on the Fourier–Bessel series (FBS) system of vector functions and the stiffness matrix method is proposed to study the dynamic response of axially loaded piles embedded in transversely isotropic (TI) layered soil.

Restriction‐Weighted Q‐Space Trajectory Imaging (ResQ): Toward Mapping Diffusion‐Time Effects With Tensor‐Valued Diffusion Encoding in Human Prostate Cancer Xenografts

open access: yesNMR in Biomedicine, Volume 39, Issue 8, August 2026.
Tensor‐valued diffusion MRI enables microstructure characterization but can be confounded by the presence of restricted diffusion. We introduce ResQ, a framework that incorporates restriction weighting into q‐space trajectory imaging and we evaluate it in a longitudinal study of prostate cancer xenografts treated by external radiotherapy. ResQ revealed

Perturbative Analytical Construction of Bowen–York Initial Data for Binary Black Holes up to Third Order in Spin and Linear Momentum

open access: yesFortschritte der Physik, Volume 74, Issue 8, August 2026.
ABSTRACT We analytically construct initial data for binary black hole systems by solving the Einstein constraint equations within the Bowen–York framework. Allowing for arbitrarily oriented linear momenta and spins, we obtain a perturbative solution of the vacuum Hamiltonian constraint up to third order in the source parameters. Our solution explicitly

Boundary‐Only Weak Deflection by Regular Black Holes, Black‐Bounces, Wormholes, and Static Quadrupolar Spacetimes

open access: yesFortschritte der Physik, Volume 74, Issue 8, August 2026.
ABSTRACT We apply the boundary‐only isothermal formulation of finite‐distance weak gravitational deflection to regular black holes, black‐bounces, traversable wormholes, non‐asymptotically flat backgrounds, and static quadrupolar spacetimes. The methodological advance is not a new value for a known bending angle.

Reappraisal of Holocene Caldera Resurgence at Campi Flegrei (Southern Italy): A Long‐Lived Magma‐Driven Resurgent Dome System

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Caldera systems commonly experience inner resurgence, which shapes patterns of volcanic activity. However, incomplete reconstructions of past ground deformation can lead to incorrect recognition of precursory signals. The Campi Flegrei caldera (Italy) provides an exceptional opportunity to address this issue as uplifted marine sediments ...

On the Leaky Nature of Fractures in Low‐Permeability Rock

open access: yesWater Resources Research, Volume 62, Issue 8, August 2026.
Abstract Hydraulic‐test interpretation in fractured rock commonly assumes impermeable confining matrices, an assumption we show is systematically incorrect, even when the matrices are 7–14 orders of magnitude less permeable than the fracture. Fluid injected into a fracture begins to leak into the surrounding rock matrices within milliseconds to seconds,
