The Climate Modeling Alliance Atmosphere Dynamical Core: Concepts, Numerics, and Scaling

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract This paper presents the dynamical core of the Climate Modeling Alliance (CliMA) atmosphere model, designed for efficient simulation of a wide range of atmospheric flows across scales. The core uses the nonhydrostatic equations of motion for a deep atmosphere, discretized with a hybrid approach that combines a spectral element method (SEM) in ...

The central parsecs of active galactic nuclei: challenges to the torus

open access: yes, 2014
Type 2 AGN are by definition nuclei in which the broad-line region and continuum light are hidden at optical/UV wavelengths by dust. Via accurate registration of infrared (IR) Very Large Telescope adaptive optics images with optical \textit{Hubble Space ...

Differential returns from networking behaviours for men and women: A longitudinal study

open access: yesJournal of Occupational and Organizational Psychology, Volume 99, Issue 1, March 2026.
Abstract Networking is an important career self‐management strategy that affects objective and subjective career outcomes. Concerning gender differences, the prevailing assumption is that women benefit less from networking than men. Yet, some findings on the effects of specific subdimensions of networking suggest that although men benefit from most ...

A strong shallow heat source in the accreting neutron star MAXI J0556-332

open access: yes, 2015
An accretion outburst in an X-ray transient deposits material onto the neutron star primary; this accumulation of matter induces reactions in the neutron star's crust.

Large Variations in the Transpiration of Sorghum Canopies Under High Evaporative Demand Are Positively Related to Water Use Efficiency

open access: yesPlant, Cell &Environment, Volume 49, Issue 3, Page 1544-1560, March 2026.
ABSTRACT Transpiration restriction under high vapour pressure deficit (VPD), measured indoors with individual plants, increases water use efficiency (WUE). However, VPD is not the only factor driving transpiration, individual plants in a field rapidly become a canopy, and reports on the transpiration restriction versus WUE are scant.

Coloring and density theorems for configurations of a given volume

open access: yesProceedings of the London Mathematical Society, Volume 132, Issue 3, March 2026.
Abstract This is a treatise on finite point configurations spanning a fixed volume to be found in a single color‐class of an arbitrary finite (measurable) coloring of the Euclidean space Rn$\mathbb {R}^n$, or in a single large measurable subset A⊆Rn$A\subseteq \mathbb {R}^n$.

Kinematics of the X-shaped Milky Way Bulge: Expectations from a Self-consistent N-body Model

open access: yes, 2015
We explore the kinematics (both the radial velocity and the proper motion) of the vertical X-shaped feature in the Milky Way with an N-body bar/bulge model.

The undecidability of joint embedding and joint homomorphism for hereditary graph classes

open access: yes, 2019
We prove that the joint embedding property is undecidable for hereditary graph classes, via a reduction from the tiling problem. The proof is then adapted to show the undecidability of the joint homomorphism property as well.Comment: 17 pages; DMTCS ...
