Explicit‐Implicit Material Point Method for Dense Granular Flows With a Novel Regularized µ(I) Model

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 7, Page 3256-3273, May 2026.
ABSTRACT The material point method (MPM) is widely employed to simulate granular flows. Although explicit time integration is favored in most current MPM implementations for its simplicity, it cannot rigorously incorporate the incompressible µ(I)‐rheology, an efficient model ubiquitously adopted in other particle‐based numerical methods. While operator‐

Measurements of the Low-acceleration Gravitational Anomaly from the Normalized Velocity Profile of Gaia Wide Binary Stars and Statistical Testing of Newtonian and Milgromian Theories

The Astrophysical Journal
Low-acceleration gravitational anomaly is investigated with a new method of exploiting the normalized velocity profile $\tilde{v}\equiv {v}_{p}/{v}_{c}$ of wide binary stars as a function of the normalized sky-projected radius s / r _M , where v _p is ...

Mass Transfer Characteristics and Entropy Generation of Rotating Non‐Uniform Surfaces With Coriolis Forces and Dissipative Eyring–Powell Flows

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 5, May 2026.
ABSTRACT This study delves into the heat and mass transfer Coriolis force of the Eyring–Powell fluid on a rotating upper horizontal surface of a paraboloid of revolution (UHSPR). The reigning equations are formulated to have terms of rotation, mass transfer and non‐linearity of fluids.

Bayesian Inference of Gravity through Realistic 3D Modeling of Wide Binary Orbits: General Algorithm and a Pilot Study with HARPS Radial Velocities

The Astrophysical Journal Letters
When 3D relative displacement r and velocity v between the pair in a gravitationally bound system are precisely measured, the six measured quantities at one phase can allow elliptical orbit solutions at a given gravitational parameter G .

Forward and Adjoint Calculations of Gravitational Potential in Heterogeneous, Aspherical Planets

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract We have developed a computational package for the calculation of numerically exact internal and external gravitational potential, its functional derivatives and sensitivity kernels, in an aspherical, heterogeneous planet. We detail our implementation, utilizing a transformation of the Poisson equation into a spherical reference domain, as well

Influence of Inherited Rifted Margin Architecture on Continental Collision Dynamics

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Continental collision is a key process in lithospheric evolution, driving mountain building, crustal thickening, and supercontinent assembly. Within the Wilson cycle, collision marks the final stage following rifting, ocean spreading, and subduction.

Probing the Nature of Gravity in the Low-acceleration Limit: Wide Binaries of Extreme Separations with Perspective Effects

The Astrophysical Journal
Recent statistical analyses of wide binaries have revealed a boost in gravitational acceleration with respect to the prediction by Newtonian gravity at low internal accelerations ≲10 ^−9 m s ^−2 .

Non‐Migrating Thermal Tides in the Martian Lower Atmosphere Observed by EMM/EMIRS

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Thermal tides significantly influence Martian atmospheric dynamics and radiative transfer. However, the excitation mechanisms of non‐migrating tides, exhibiting diverse spatial structures, remain poorly understood due to the limited number of observations.

Angular Momentum Balance of Superrotation in Venus's Middle and Upper Atmosphere Simulated by AFES‐Venus

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Based on simulations of the Venusian atmosphere using the AFES‐Venus GCM, we investigated the angular momentum (AM) balance that maintains the atmospheric superrotation (SR) at 35–90 km altitudes. In and above the cloud layer, the Eulerian‐mean meridional circulation consists of Hadley‐like cells at low latitudes and Ferrel‐like cells at ...
