Pointwise multipliers for reverse Hölder spaces. II
, 1995 The author completes work begun in [Stud. Math. 109, No. 1, 23-39 (1994; Zbl 0844.42008)]. Let \(\Omega\) be an open subset of \(R^n\). A cube \(Q\) is always assumed to have faces perpendicular to the coordinate axes, and its length is denoted \(l(Q)\). If \(t>0\), \(tQ\) is the cube concentric with \(Q\) such that \(l(tQ) = tl(Q)\).

Nonparametric Survival Estimation With Contaminated and Adjudicated Events
Scandinavian Journal of Statistics, EarlyView.ABSTRACT We study the conditional expert Kaplan–Meier estimator, an extension of the classical Kaplan–Meier estimator designed for time‐to‐event data subject to both right‐censoring and contamination. Such contamination, where observed events may not reflect true outcomes, is common in applied settings, including insurance and credit risk, where expert

Simple Analytics and Empirics of the Government Spending Multiplier and Other “Keynesian” Paradoxes [PDF]
Factor supply increases (depresses) output for many of the same reasons that the government spending multiplier might be less (greater) than one. Data from three 2008-9 recession episodes - the labor supply shifts associated with the seasonal cycle, the ...

Architecture of the cardiac transverse–axial tubular system across different mammalian species
The Journal of Physiology, EarlyView.Abstract figure legend Mammalian species differ in ventricular TATS architecture, and cytoplasmic distance to the nearest TATS element covaries with lifespan, body mass, and resting heart rate. Abstract Cardiac excitation–contraction coupling relies on a pancellular network of regular cardiomyocyte surface membrane invaginations, termed the transverse ...

Stability of Viscous Three‐Dimensional Stratified Couette Flow via Dispersion and Mixing
Communications on Pure and Applied Mathematics, Volume 79, Issue 12, Page 2435-2490, December 2026.ABSTRACT This article explores the stability of stratified Couette flow in the viscous 3d$3d$ Boussinesq equations. In this system, mixing effects arise from the shearing background, and gravity acts as a restoring force leading to dispersive internal gravity waves.

Pointwise multipliers on Musielak-Orlicz spaces
, 2016 We consider the pointwise multipliers on Musielak-Orlicz spaces. We treat a wide class of Musielak-Orlicz spaces with generalized Young functions which include quasi-normed spaces.

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT In this work, novel electrostatic aspects of sharp cracks in brittle dielectrics are discussed using the example of an impermeable Griffith crack in an infinite linear isotropic dielectric plate. On the one hand, electrostatic force densities stemming from the Maxwell stress tensor according to Lorentz are derived mathematically, where the ...

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT We present an efficient multi‐object map‐matching approach for scene modeling in the context of automated driving. The mapping of traffic participants to the road topology is a key component of the scene modeling step in the processing pipeline for situation‐aware automated driving.

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT We develop a physics‐informed Fourier Neural Operator (PINO) for the surrogate modeling of full‐field responses in polycrystalline microstructures. Reference stress and strain fields are generated using an FFT‐based full‐field solver under prescribed macroscopic loading. The model maps the crystallographic orientation field q(x)$\bm{q}(\bm{x})$

Global Graph Surrogates and Neural Graph Elements for Computational Mechanics
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT Machine learning surrogates are increasingly used to accelerate physics‐based simulations by predicting full‐field responses at a fraction of the computational cost. In this contribution, we present two complementary graph‐based approaches for surrogate modelling in computational mechanics.
