Reactive Mixing Fronts in Porous Media Under Transverse Velocity Gradients

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Mixing‐limited reactions in porous media depend on concentration gradients at interfaces, yet their behavior in nonuniform co‐flow remains poorly understood. Here we develop a closed‐form theory for irreversible reactions A+B→P $A+B\to P$ in a co‐flow where a transverse velocity gradient makes transverse hydrodynamic dispersion vary linearly ...

Multiple Bound States in the Continuum in Deep‐Subwavelength Nonlocal Polar Dielectric Nanoparticles

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
Spatial dispersion in polar‐dielectric core–shell nanoparticles enable multiple deep‐subwavelength bound states in the continuum through longitudinal‐transverse hybrid modes. By suppressing radiative damping at finite geometrical parameters, these nonlocality‐induced BICs provide a compact platform for high Q light confinement, enhanced light–matter ...

Geostatistical Modelling and Web‐Based Mapping of Malaria Risks Among Children Under Five Years in Nigeria: Evidence From the 2021 Nigeria Malaria Indicator Survey

Health Science Reports, Volume 9, Issue 8, August 2026.
ABSTRACT Background Malaria is a critical public health concern in Nigeria with the country bearing an uneven burden of the disease. In Nigeria, malaria is one of the main causes of child mortality and despite all efforts to reduce malaria mortality rates, the disease remains a major concern, notably among children under‐fives.

Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies

Laser &Photonics Reviews, Volume 20, Issue 15, 7 August 2026.
Position–momentum entanglement constitutes a high‐dimensional continuous‐variable resource in quantum optics. Recent advances in its generation, characterization, and control are reviewed, with emphasis on spontaneous parametric down‐conversion and modern measurement techniques.

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

International 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.

Detecting When One Probe Vector is Enough for Preconditioned Log‐Determinant Approximation

Numerical Linear Algebra with Applications, Volume 33, Issue 4, August 2026.
ABSTRACT We present randomized algorithms for estimating the log‐determinant of regularized symmetric positive semi‐definite matrices. The algorithms access the matrix only through matrix vector products, and are based on the introduction of a preconditioner and stochastic trace estimator.

Signal Data Stream Parameters Passing Ionospheric Communication Links With Fading Caused by Natural Clutter Phenomena

Radio Science, Volume 61, Issue 8, August 2026.
Abstract This paper explores the impact of natural phenomena on signal data transmission across various ionospheric communication channels. The study focuses on three primary phenomena: meteor trails prevalent in the middle‐ and lower‐latitude ionosphere, bubble and plume structures observed around the equatorial ionosphere, and magnetic‐storm‐induced ...

Quantifying Uncertainty in OMNI Solar Wind Measurements Projected From L1 to the Earth's Bow Shock

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Many routine measurements of the solar wind plasma and interplanetary magnetic field (IMF) are made at the L1 Sun–Earth Lagrange point; therefore, it is helpful to characterize the errors introduced in propagating these measurements to the near‐Earth environment.

Ray Tracing Method in a General Non‐Dipole Magnetic Field

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract We present a new general mathematical formulation of the Eikonal equations for ray tracing, which can use any internal magnetic field model. The analytical and tractable expressions are conveniently based on a vector formalism, which is independent of any coordinate system.
