Bounded diameter monochromatic component covers

Mathematika, Volume 72, Issue 4, October 2026.
Abstract Ryser conjectured that every r$r$‐edge‐coloured complete graph can be covered by r−1$r-1$ monochromatic trees. Motivated by a question of Austin in analysis, Milićević predicted something stronger — that every r$r$‐edge‐coloured complete graph can be covered by r−1$r-1$ monochromatic trees of bounded diameter.

Remarks on quiver gauge theories from open topological string theory [PDF]

, 2010
We study effective quiver gauge theories arising from a stack of D3-branes on certain Calabi-Yau singularities. Our point of view is a first principle approach via open topological string theory.

Exact Discrete Stochastic Simulation With Deep‐Learning‐Scale Gradient Optimization

Advanced Science, Volume 13, Issue 52, 18 September 2026.
A 203,796‐parameter gene regulatory network classifies handwritten digits with 98.4% accuracy using exact stochastic dynamics. The framework decouples forward simulation from backward differentiation, making continuous‐time Markov chain models compatible with deep‐learning optimization.

Disrupted Functional Network Organization in Crohn's Disease: Interoceptive Alterations Linked to Anxiety

CNS Neuroscience &Therapeutics, Volume 32, Issue 9, September 2026.
Crohn's disease shows widespread disruption and reorganization of functional brain networks, with altered activity in core interoceptive regions involved in sensory and emotional processing. Emotional disturbances modulate brain network dynamics, providing insight into neural mechanisms linking disease activity and affective symptoms.

Universum Inspired Graph Contrast Learning for Major Depressive Disorder Identification: In Functional Brain Network View

CNS Neuroscience &Therapeutics, Volume 32, Issue 9, September 2026.
Uni‐GCL pretrains a spatio‐temporal GCN on rs‐fMRI functional brain networks using two‐level augmentation and mixup‐based universum samples for self‐supervised contrastive learning. With only a small labeled target set, it improves cross‐site MDD identification and provides node‐wise interpretability via graph Grad‐CAM.

Spatial Lock‐In and Reclamation Delay in Coal‐Subsidence Landscapes: Land Degradation Under Passive Water‐Retention Strategies

Land Degradation &Development, Volume 37, Issue 15, Page 11048-11060, September 2026.
ABSTRACT In coal‐grain composite regions, intensive underground coal extraction causes large‐scale surface subsidence; under shallow groundwater conditions, these subsided landscapes rapidly transform former croplands into persistent open water bodies, creating long‐term inundated landscapes. Passive water‐retention strategies in these areas often rely

Predicting the Toxicity of Chemical Compounds via Hyperdimensional Computing

Molecular Informatics, Volume 45, Issue 9, September 2026.
Hyperdimensional computing converts text representations of chemical structures (SMILES) into high‐dimensional vectors. New compounds are classified by comparison with learned toxic and nontoxic reference patterns; across 12 Tox21 targets, overlapping four‐character SMILES patterns performed best among tested representations, supporting fast ...

Pointvalue characterizations in multi-parameter algebras [PDF]

We extend classical results from the Colombeau algebra, concerning point-value characterizations of generalized functions, to the more general case of multi-parameter (C,E,P)–algebras. Our investigations include considerations about different definitions
