Rational points in a family of conics over F2(t)$\mathbb {F}_2(t)$

Mathematische Nachrichten, Volume 299, Issue 3, Page 496-513, March 2026.
Abstract Serre famously showed that almost all plane conics over Q$\mathbb {Q}$ have no rational point. We investigate versions of this over global function fields, focusing on a specific family of conics over F2(t)$\mathbb {F}_2(t)$ which illustrates new behavior.

Group Codes Over Dihedral Group Algebras 𝔽q[D16] and 𝔽q[Z2 × D8]

Journal of Mathematics
Let Fq denote a finite field of characteristic p, where q=pk for some prime p and integer k. Let Dn represent a dihedral group of order n. In this paper, group codes in the dihedral group algebras FqD16 and FqZ2×D8 are proposed.

Methodological Frameworks for Computational Electrocatalysis: From Theory to Practice

Small Methods, Volume 10, Issue 5, 9 March 2026.
Computational modeling is widely used to investigate electrocatalytic reactions, yet accurately describing electrochemical interfaces remains challenging. This review outlines theoretical and computational strategies, based on density functional theory, to model reaction thermodynamics, solvation effects, applied bias, and kinetics.

The Evolving Landscape of Modern Regression: A Systematic Review and Mapping Study of Penalized, Algorithmic, and Interpretable Models

WIREs Data Mining and Knowledge Discovery, Volume 16, Issue 1, March 2026.
This systematic review maps 50 years of regression methodology, tracing its evolution from ridge stabilization and penalized estimation to Bayesian, ensemble, and explainable‐AI frameworks. The analysis reveals a unified progression toward interpretable, cross‐domain modeling that integrates statistical rigor, computational scalability, and epistemic ...

High‐energy synchrotron X‐ray multimodal computed tomography: enabling multiscale materials characterization at NSLS‐II

Journal of Synchrotron Radiation, Volume 33, Issue 2, Page 531-542, March 2026.
The development of multimodal X‐ray computed tomography capabilities, including imaging, fluorescence, diffraction, and scattering, at the 28‐ID‐2 beamline of the National Synchrotron Light Source II is described.We report the commissioning of a multimodal computed tomography experimental setup at the 28‐ID‐2 (XPD) beamline of the National Synchrotron ...

Optimal Refund Mechanism With Consumer Learning

The RAND Journal of Economics, Volume 57, Issue 1, Page 205-224, Spring 2026.
ABSTRACT This article studies the optimal refund mechanism when an uninformed buyer learns about their valuation over time. We consider various refund mechanisms including simple return policies (no returns or free returns), and stochastic return policies, which allow the buyer to keep the product with some probability upon receiving a refund.

A Recurrence Relation Approach to Higher Order Quantum Superintegrability

Symmetry, Integrability and Geometry: Methods and Applications, 2011
We develop our method to prove quantum superintegrability of an integrable 2D system, based on recurrence relations obeyed by the eigenfunctions of the system with respect to separable coordinates.

Multivariate representations of univariate marked Hawkes processes

Scandinavian Journal of Statistics, Volume 53, Issue 1, Page 140-174, March 2026.
Abstract Univariate marked Hawkes processes are used to model a range of real‐world phenomena including earthquake aftershock sequences, contagious disease spread, content diffusion on social media platforms, and order book dynamics. This paper illustrates a fundamental connection between univariate marked Hawkes processes and multivariate Hawkes ...
