Joint distribution of Hecke eigenforms on H3$ \mathbb {H}^3$
Mathematische Nachrichten, Volume 299, Issue 3, Page 661-674, March 2026.Abstract We prove a joint value equidistribution statement for Hecke–Maaß cusp forms on the hyperbolic three‐space H3$\mathbb {H}^3$. This supports the conjectural statistical independence of orthogonal cusp forms.

Archimedean Copulae and Positive Dependence. [PDF]
In the first part of the paper we consider positive dependence properties of Archimedean copulae. Especially we characterize the Archimedean copulae that are multivariate totally positive of order 2 (MTP2) and conditionally increasing in sequence. In the

An Exploration of Motion‐Sampling Interactions in 3D MRI for Neuroimaging
Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1448-1461, March 2026.ABSTRACT Purpose To investigate how rigid head motion interacts with 3D MRI k‐space sampling strategies and to introduce motion‐sampling plots as a framework for predicting motion artifacts. Methods We evaluated a range of motion‐sampling combinations across three sampling trajectories (Cartesian, stack‐of‐stars, kooshball) in both simulation and in ...

Permutation Tests Based on the Copula‐Graphic Estimator and Their Use for Survival Tree Construction
Statistics in Medicine, Volume 45, Issue 6-7, March 2026.ABSTRACT Survival trees are popular alternatives to Cox or Aalen regression models that offer both modeling flexibility and graphical interpretability. This paper introduces a new algorithm for survival trees that relaxes the assumption of independent censoring. To this end, we use the copula‐graphic estimator to estimate survival functions.

Market Insurance and Risk Pooling in U.S. Crop Insurance
Agricultural Economics, Volume 57, Issue 2, March 2026.ABSTRACT A common assumption is that multiple‐peril crop insurance markets suffer from market failures, thus justifying government intervention in the form of premium subsidies, operating allowances, and reinsurance agreements. One prominent rationale for intervention involves geographic correlation in agricultural production which leads to systemic ...

McDowell and Sellars on Objective Purport
European Journal of Philosophy, Volume 34, Issue 1, Page 313-332, March 2026.Abstract John McDowell has criticized Wilfrid Sellars on several occasions and over a number of years for his ‘non‐relational’ account of intentionality. This account is, according to McDowell, at least partly responsible for a ‘blind spot’ in Sellars's thinking: Sellars, allegedly, fails to see how objects or states of affairs in the external world ...

Research about the number of D-points of -tiling in given ellipse
Journal of Hebei University of Science and Technology, 2017 An Archimedean tiling is a tiling of the plane by one type of regular polygon or several types of regular polygons, and every vertex of the tiling has the same vertex characteristics.

Noûs, Volume 60, Issue 1, Page 16-37, March 2026.Abstract Standard decision theory ranks risky prospects by their expected utility. This ranking does not change if the values of all possible outcomes are uniformly shifted or dilated. Similarly, if the values of the outcomes are negated, the ranking of prospects by their expected utility is reversed.

Simple archimedean dimension groups [PDF]
Proceedings of the American Mathematical Society, 2013 We answer a question of Goodearl, by constructing for every metrizable Choquet simplex, a dimension group that is simple and archimedean and whose trace space is the desired Choquet simplex.

p$p$‐adic equidistribution and an application to S$S$‐units
Journal of the London Mathematical Society, Volume 113, Issue 3, March 2026.Abstract We prove a Galois equidistribution result for torsion points in Gmn$\mathbb {G}_m^n$ in the p$p$‐adic setting for test functions of the form log|F|p$\log |F|_p$ where F$F$ is a nonzero polynomial with coefficients in the field of complex p$p$‐adic numbers.
