Linear representations of soluble groups of finite Morley rank [PDF]

Proceedings of the American Mathematical Society, 2010
Sufficient conditions are given for groups of finite Morley rank having nontrivial torsion-free nilpotent normal subgroups to have linear representations with small kernels. In particular, centreless connected soluble groups of finite Morley rank with torsion-free Fitting subgroups have faithful linear representations.

Alcohol craving under stress in healthy young men: A randomized laboratory study

Alcohol, Clinical and Experimental Research, Volume 50, Issue 2, February 2026.
This study shows that acute social stress can increase alcohol craving in young men. Individuals with stronger mood and biological reactivity showed greater increases in craving. Two latent classes of stress‐craving effects emerged in exploratory analyses: one class showed stress‐induced craving increase while the other showed a decrease compared with ...

The legacy of the Cartwright–Littlewood collaboration

Journal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract Mary L. Cartwright and John E. Littlewood published a short “preliminary survey” in 1945 describing results of their investigation of the forced van der Pol equation ÿ−k(1−y2)ẏ+y=bλkcos(λt+a)$$\begin{equation*} \ddot{y}-k(1-y^2)\dot{y}+y = b \lambda k \cos (\lambda t+a) \end{equation*}$$in which b,λ,k,a$b,\lambda,k,a$ are parameters with k$k$

Intercropping Broccoli‐Basil Reduces Aphid Growth: Spatio‐Temporal Modelling Across Scales and Lab Experiments

Journal of Sustainable Agriculture and Environment, Volume 4, Issue 4, December 2025.
ABSTRACT Shifting from conventional to sustainable agriculture demands well‐designed experiments and robust analytical models to evaluate agroecological system performance and resilience. We modelled aphid population dynamics in broccoli monocultures and broccoli‐basil intercrops using spatio‐temporal approaches, informed by laboratory experiments on ...

Temperature‐Dependent Speciation in the Sundaland Region Driven by Interglacial Refugial Isolation in the Bulbophyllum lobbii Complex (Orchidaceae)

Journal of Biogeography, Volume 52, Issue 12, December 2025.
ABSTRACT Aim The historical origins of biota in the Sunda Shelf region of Southeast Asia represent a long‐standing contentious issue in evolutionary biology. However, there is still no general agreement on the key factors driving the region's high species diversity and endemism in both plants and animals. Here, we inferred the evolutionary history of a

The Evolution of Fault Networks During Multiphase Triaxial and Biaxial Strain: An Analogue Modeling Approach

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract Extensional tectonic settings may undergo time‐dependent kinematic changes, causing a multiphase evolution of the resulting fault networks. Yet, the spatial and temporal evolution of fault networks during triaxial and biaxial strain remains underexplored.

Indiscernibles in monadically NIP theories

Bulletin of the London Mathematical Society, Volume 57, Issue 11, Page 3326-3345, November 2025.
Abstract We prove various results around indiscernibles in monadically NIP theories. First, we provide several characterizations of monadic NIP in terms of indiscernibles, mirroring previous characterizations in terms of the behavior of finite satisfiability. Second, we study (monadic) distality in hereditary classes and complete theories.

High‐Entropy Magnetism of Murunskite

Advanced Functional Materials, Volume 35, Issue 40, October 1, 2025.
The study of murunskite (K2FeCu3S4) reveals that its magnetic and orbital order emerges in a simple I4/mmm crystal structure with complete disorder in the transition metal positions. Mixed‐valence Fe ions randomly occupy 1/4 of the tetrahedral sites, with the remaining 3/4 being filled by non‐magnetic Cu+ ions.

Occurrence Rates and Variability of Whistler‐Mode Waves in the Plasma Trough

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract Numerical models of energetic electron behavior in the outer radiation belt require descriptions of the wave‐particle interactions across the inner magnetosphere. Quasilinear diffusion coefficients describe gyro‐resonant wave‐particle interactions over large time‐ and length‐scales but these must be constrained by observations to construct ...
