Methods to estimate marine functional connectivity: A primer

Ecological Applications, Volume 36, Issue 4, June 2026.
Abstract Organism movement is a key process in the transfer of individuals, genes, functional traits, matter, and energy among habitat patches, at sea and across the land–sea interface. The resulting fluxes, collectively termed marine functional connectivity (MFC), underpin planetary health and an array of ecosystem services.

Optimizing the Collaborative Supply Scheduling of Renewable Energy in the Tourism Industry Chain Using Graph Neural Networks

Engineering Reports, Volume 8, Issue 6, June 2026.
Typical configuration of Huangshan Scenic Area. ABSTRACT To cope with the supply and demand imbalance challenge caused by the surge in energy demand in tourism‐intensive areas and the high volatility of renewable energy, this paper aims to construct a collaborative scheduling optimization model based on graph neural networks (GNNs). The model abstracts

On intermediate exceptional series

The Freudenthal–Tits magic square  for  of semi-simple Lie algebras can be extended by including the sextonions . A series of non-reductive Lie algebras naturally appear in the new row associated with the sextonions, which we will call the intermediate ...

An Empirical Investigation of Adaptive Cognitive Guidance Strategy Optimization Driven by Hierarchical Chain‐of‐Thought Reasoning in Large Language Models

Engineering Reports, Volume 8, Issue 6, June 2026.
This study proposes an adaptive cognitive counseling strategy based on hierarchical thinking chain. This strategy constructs a three‐layer reasoning framework consisting of strategy layer, tactics layer, and detail layer, and decomposes complex problems into operational cognitive units.

A Comprehensive Multistage Average Controller for Trajectory Tracking in Solar‐Powered Mobile Robots: Analysis of Actuator‐Driver and Power Stage Integration

International Journal of Mechanical System Dynamics, Volume 6, Issue 2, Page 224-246, June 2026.
ABSTRACT This work addresses the challenge of bidirectional trajectory tracking in solar‐powered wheeled mobile robots (WMRs), considering the mechanical structure, actuator‐driver, and power stage subsystems. Notably, this is the first study to explicitly model and control the actuator‐driver subsystem within this context. The proposed solution relies

DIVIDED POWER (CO)HOMOLOGY. PRESENTATIONS OF SIMPLE FINITE DIMENSIONAL MODULAR LIE SUPERALGEBRAS WITH CARTAN MATRIX

, 2010
For modular Lie superalgebras, new notions are introduced: Divided power homology and divided power cohomology. For illustration, we explicitly give presentations (in terms of analogs of Chevalley generators) of finite dimensional Lie (super) algebras ...

Covariance Estimation for Wide Data

WIREs Computational Statistics, Volume 18, Issue 2, June 2026.
Covariance matrix estimation is fundamental to multivariate analysis, with applications spanning finance, genomics, climate science, and signal processing. This review synthesizes recent advances in high‐dimensional covariance estimation‐thresholding, linear and nonlinear shrinkage, graphical models, and random matrix theory‐under a unifying framework ...

Integrated Hydrological and Hydrodynamic Modeling for Mountainous Flooding—A Case Study in China

Journal of Flood Risk Management, Volume 19, Issue 2, June 2026.
ABSTRACT Flooding in mountain regions has caused significant economic loss globally. Due to the complexity of mountainous flooding, that is, heavy runoff, landslides and debris flow, and limited monitoring data, it is extremely difficult to simulate and predict such events.

The singularity category and duality for complete intersection groups

Bulletin of the London Mathematical Society, Volume 58, Issue 6, June 2026.
Abstract If G$G$ is a finite group, the structure of the modular representation theory depends on the cochains C∗(BG;k)$C^*(BG; k)$, viewed as a commutative ring spectrum. We consider here its singularity category (in the sense of the author and Stevenson [Adv. Math.

On the cohomology of finite‐dimensional nilpotent groups and Lie rings

Bulletin of the London Mathematical Society, Volume 58, Issue 6, June 2026.
Abstract We establish vanishing results for the first cohomology group of nilpotent groups and Lie rings when the submodule of invariants is trivial. Our results are obtained within a model‐theoretic setting, namely for structures that are definable in a finite‐dimensional theory, which encompasses algebraic groups over algebraically closed fields ...
