Vector bundles on bielliptic surfaces: Ulrich bundles and degree of irrationality
Mathematische Nachrichten, Volume 299, Issue 3, Page 514-528, March 2026.Abstract This paper deals with two problems about vector bundles on bielliptic surfaces. The first is to give a classification of Ulrich bundles on such surfaces S$S$, which depends on the topological type of S$S$. In doing so, we study the weak Brill–Noether property for moduli spaces of sheaves with isotropic Mukai vector. Adapting an idea of Moretti

Earth and Space Science, Volume 13, Issue 3, March 2026.Abstract This study presents a supervised machine learning approach to constructing a 3D geological model for the Lockington area in Victoria, Australia, by integrating borehole observations, geophysical surveys (magnetic, gravity, and radiometric), and elevation data.

Terwilliger $\mathbb{F}$-algebras of certain Cayley tables
, 2023 Let $\mathbb{F}$ be an arbitrary field. In this paper, we continue studying the Terwilliger algebras of association schemes over $\mathbb{F}$ that were called the Terwilliger $\mathbb{F}$-algebras of association schemes in [8]. We determine the algebraic structures of the Terwilliger $\mathbb{F}$-algebras of the association schemes induced from the ...

Advanced Materials, Volume 38, Issue 8, 6 February 2026.Electret‐style organic thin‐film transistors are evaluated for synchrotron X‐ray dosimetry at ultra‐high dose rates, showing promising performance and agreement with standard detectors. XPS and NEXAFS reveal radiation‐induced oxidation and Fermi level shifts in pentacene and polystyrene, correlating with reduced charge carrier mobility and providing ...

Advancing Quantum Process Tomography Through Quantum Compilation
Advanced Quantum Technologies, Volume 9, Issue 2, February 2026.A compilation‐based quantum process tomography (CQPT) framework is introduced for efficient characterization of noisy quantum dynamics. The method reconstructs quantum processes using single‐shot measurements and trainable process representations, avoiding full POVM tomography.

A tropical approach to rigidity: Counting realisations of frameworks
Journal of the London Mathematical Society, Volume 113, Issue 2, February 2026.Abstract A realisation of a graph in the plane as a bar‐joint framework is rigid if there are finitely many other realisations, up to isometries, with the same edge lengths. Each of these finitely many realisations can be seen as a solution to a system of quadratic equations prescribing the distances between pairs of points.

Small Partial Latin Squares that Cannot be Embedded in a Cayley Table [PDF]
, 2015 We answer a question posed by D nes and Keedwell that is equivalent to the following. For each order $n$ what is the smallest size of a partial latin square that cannot be embedded into the Cayley table of any group of order $n$? We also solve some variants of this question and in each case classify the smallest examples that cannot be embedded.
