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.

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.

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

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

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.

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
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,
