Non‐negative Gaussian estimation of variance components in random effects models

open access: yesCanadian Journal of Statistics, Volume 54, Issue 2, June 2026.
Abstract When used to estimate variance components (VCs), confidence intervals (CIs) can be truncated at zero, have a point estimate not in the quoted CI, be empty with positive probability, or be all‐inclusive. This is because they have conflicting dual roles, since they are considered to cover the parameter with a specified probability while also ...

Ringdown Modulation of Acceleration Radiation in the Schwarzschild Background

open access: yesFortschritte der Physik, Volume 74, Issue 6, June 2026.
ABSTRACT We derive an analytic first‐order description of how Schwarzschild ringdown affects a detector‐based detailed‐balance diagnostic in a near‐horizon, single‐mode setting. A freely falling two‐level system couples to a cavity‐filtered outgoing mode of fixed asymptotic frequency, whose static Schwarzschild response gives geometric photon ...

Quadratic Residues and Non-Residues [electronic resource] : Selected Topics /

open access: yes
This book offers an account of the classical theory of quadratic residues and non-residues with the goal of using that theory as a lens through which to view the development of some of the fundamental methods employed in modern elementary, algebraic, and

Efficient Simulation of Noisy Entanglement Generation

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 6, June 2026.
End‐to‐end entanglement distribution is essential for future quantum internet. The work introduces analytical tools and an upgraded SeQUeNCe simulator for scalable, realistic entanglement‐generation simulations. The method directly estimates success probability, output state, and fidelity under practical noise sources, including dark counts and ...

A Unified Vector Electromagnetic Framework for Ionospheric Scintillation and Polarization Effects in GNSS

open access: yesRadio Science, Volume 61, Issue 6, June 2026.
Abstract The ionosphere imposes coupled amplitude, phase, and polarization distortions on trans‐ionospheric Global Navigation Satellite System (GNSS) signals, reflecting the structure and dynamics of electron‐density irregularities. Classical weak‐scatter theory provides a mature framework for interpreting amplitude and phase scintillation, but these ...

Legume genome structures and histories inferred from Cercis canadensis and Chamaecrista fasciculata genomes

open access: yesThe Plant Journal, Volume 126, Issue 5, June 2026.
SUMMARY The legume family originated ca. 60–65 million years ago and soon diversified into at least six lineages (now extant subfamilies). The signal of whole genome duplications (WGD) is apparent in species sampled from all six subfamilies. The early diversification has posed difficulties for resolving the legume backbone structure and the timing of ...

Generalized free wreath products and their operator algebras

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 6, June 2026.
Abstract We develop a new approach on free wreath products, generalizing the constructions of Bichon and of Fima‐Pittau. We show stability properties for certain approximation properties such as exactness, Haagerup property, hyperlinearity, and K‐amenability. We study qualitative properties of the associated von Neumann algebra: factoriality, primeness,
