Generalization of Motor Learning in Psychological Space
Topics in Cognitive Science, EarlyView.Abstract The capacity to generate adaptive movements largely depends on how we generalize what we have previously learned to novel situations. The generalization of adapted movements has typically been framed as a consequence of neural tuning functions that overlap for similar movement kinematics—what might be considered bottom‐up generalization ...

Quantum Spectral Clustering Framework via Compact Circuit Structures
Advanced Quantum Technologies, Volume 9, Issue 10, October 2026.Can a quantum computer cluster data without ever reading the full kernel? This work shows that compact, parameterized circuits estimate the Laplacian quadratic forms directly and perform clustering, without explicitly constructing the full quantum fidelity‐kernel matrix.

Abelian number fields with frobenian conditions
Mathematika, Volume 72, Issue 4, October 2026.Abstract We study the distribution of abelian number fields with frobenian conditions imposed on the conductor. In particular, we find an asymptotic for the number of abelian field extensions of a number field k$k$ whose conductor is the sum of two squares. We also discuss an application of the Brauer group of stacks to quadratic number fields.

Discrete Limit Bohr–Jessen Type Theorem for the Epstein Zeta-Function in Short Intervals
AxiomsWe prove a probabilistic limit theorem for the Epstein zeta-function ζ(s;Q) in the interval [N,N+M] as N→∞, using discrete shifts ζ(σ+ikh;Q), where h>0 and σ>n−12 are fixed. Here, Q is a positive-definite n×n matrix, and the interval length M satisfies h−

Charlotte Pommer: Resistance fighter and female pioneer of German anatomy
Anatomical Sciences Education, Volume 19, Issue 9, Page 1415-1429, September 2026.Abstract This article examines the biography and unique case of Charlotte Pommer (1914–2004), the only anatomist documented to have left the field during the Nazi period after encountering the regime's victims on the dissection table. While she is known for her resistance activities, newly presented documentation reveals her role as the provisional ...

, 2020 According to Haar’s Theorem, every compact topological group G admits a unique (regular, right and) left-invariant Borel probability measure μ_G. Let the Haar integral (of G) denote the functional ∫_G:?(G)∋ f ↦ ∫ f d μ_G integrating any continuous ...

Entropy measures for transition matrices in random systems
SciPost Physics CoreA transition matrix can be constructed through the partial contraction of two given quantum states. We analyze and compare four different definitions of entropy for transition matrices, including (modified) pseudo entropy, SVD entropy, and ABB entropy ...

Haar measure for non-Hausdorff locally compact groups [PDF]
, 2023 The paper describes two possible ways of extending the definition of Haar measure to non-Hausdorff locally compact groups. The first one forces compact sets to be measurable: with this construction, a counterexample to the existence of the Haar measure ...

Visibility and Intersection Density for Boolean Models in Hyperbolic Space
Mathematische Nachrichten, Volume 299, Issue 9, Page 2542-2565, September 2026.ABSTRACT For Poisson particle processes in hyperbolic space we introduce and study concepts analogous to the intersection density and the mean visible volume, which were originally considered in the analysis of Boolean models in Euclidean space. In particular, we determine a necessary and sufficient condition for the finiteness of the mean visible ...
