Gradient Flows on Sparse Representations for PDE‐Regularized Inverse Problems
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT In this short paper, we summarize the theory of Atomic Gradient Flows (AGF) introduced in (Amend, Carioni and Zemas, arxiv:2603.25675, 2026), which provides a framework to construct gradient flows on sparse representations for convex regularized optimization problems.

A Chaos‐Driven Image Encryption Method With Möbius Transformations and Finite‐Ring Diffusion
Engineering Reports, Volume 8, Issue 11, November 2026.This paper presents a lightweight yet highly secure image encryption framework integrating chaotic dynamics, HKDF‐S3 key expansion, and Möbius‐Affine transformations. The proposed scheme achieves strong confusion and diffusion with minimal computational cost, demonstrating high resistance to differential and chosen‐plaintext attacks through dynamic key

Stable Cuts, NAC‐Colourings and Flexible Realisations of Graphs
Journal of Graph Theory, Volume 113, Issue 3, Page 411-427, November 2026.ABSTRACT A (2‐dimensional) realisation of a graph G is a pair ( G , p ), where p maps the vertices of G to R 2. A realisation is flexible if it can be continuously deformed while keeping the edge lengths fixed, and rigid otherwise. We say that G is rigid if every generic realisation of G is rigid; otherwise, G is flexible. In this paper, we investigate

Medical Physics, Volume 53, Issue 11, November 2026.Abstract Background Spatial resolution in preclinical cone‐beam micro‐CT is conventionally characterised by image‐domain metrics measured on a specific reconstruction of a specific phantom. Such metrics conflate resolution loss originating in the data (photon noise, angular undersampling) with resolution loss originating in the reconstruction ...

Feature‐Level Analysis and Adversarial Transfer in Rotationally Equivariant Quantum Machine Learning
Advanced Quantum Technologies, Volume 9, Issue 11, November 2026.A detailed feature‐level analysis reveals how symmetry‐dependent features relate to adversarial transfer robustness in equivariant quantum machine learning models, paving the way for the design of future models with improved robustness. ABSTRACT Group‐equivariant quantum models are designed to exploit symmetry and can improve trainability, but it ...

Maximal independence and regularity of Al/Si distributions in disordered phyllosilicates 2:1
Acta Crystallographica Section A, Volume 82, Issue 6, Page 472-485, November 2026.The distribution of aluminium cations in disordered phyllosilicates is analysed according to the concepts of maximal independence and regularity.As an extension of previous works, we analyse regularity in disordered Al/Si distributions in phyllosilicates 2:1. The method is based on an analysis of maximal independent sets in a labelled quotient graph of

When is the bait worth the risk? A mechanistic model of a compensatory ecological trap in seabirds
Functional Ecology, Volume 40, Issue 11, Page 3398-3421, November 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological traps occur when organisms preferentially select habitats that reduce fitness. In seabird–fishery systems, fishery‐derived trophic subsidies can increase foraging success, reinforce habitat preference and indirectly enhance reproductive output or recruitment,

Rethinking Mistrust: Elements Toward a Situated Theory on Immigrant Workers
Canadian Review of Sociology/Revue canadienne de sociologie, Volume 63, Issue 4, November 2026.ABSTRACT This article explores mistrust as a socially situated phenomenon by using the care trajectories of injured immigrant workers in Québec as a conceptual entry point. Rather than focusing on the individual characteristics of trusters, it examines how mistrust emerges from a subjective evaluation of environments perceived as threatening.

Making Policy Evidence Traceable: A Modular Preregistration Framework for Policy Evaluation
Policy Studies Journal, Volume 54, Issue 4, November 2026.ABSTRACT Preregistration is increasingly used in policy research, but its value depends on whether preregistered commitments can be clearly linked to reported analyses. Policy studies often involve multiple outcomes, evolving administrative data, consequential design and analytic choices, and adaptive implementation, making it difficult to distinguish ...
