Landau-Kolmogorov type inequalities for curves on Riemannian manifolds [PDF]
Summary: We obtain Landau-Kolmogorov type inequalities for mappings defined on the whole real axis and taking values in Riemannian manifolds. In terms of an auxiliary convex function, we find conditions under which the boundedness of covariant derivative along the curve under consideration ensures the boundedness of the corresponding tangent vector ...

Stochastic Hydrodynamic Velocity Field and the Representation of Langevin Equations
A lumped method is proposed to account for both mean‐field hydrodynamics and stochastic fluctuations within the kinematic equations of motion, providing a regularized formulation of the overdamped approximation. The concept of stochastic realizability in broad sense is introduced based on the spectral properties of the Fredholm operator associated with

Transition from the chaotic turbulence to the turbulent structures
Weak turbulence, similar to incoherent light, may be represented as an ensemble of quasi‐free quanta or Fourier harmonics. Unlike it, strongly turbulent state should be based on nonlinear structures. In particular, strong plasma turbulence may be constructed of discrete formations, viz., Langmuir solitons.

Physics of Ferroelectric Wurtzite Al1−xScxN Thin Films
This review highlights Al1−xScxN as a groundbreaking wurtzite ferroelectric with exceptional properties, including large polarization, tunable coercive field, outstanding thermal stability, and compatibility with CMOS/III‐N technologies. It explores the origins of its ferroelectricity, phase stability, and control mechanisms, discusses challenges such ...

Abstract One hypothesized mechanism that triggers deep‐focus earthquakes in oceanic subducting slabs below ∼300 km depth is transformational faulting due to the olivine‐to‐spinel phase transition. This study uses finite element modeling to investigate phase transformation‐induced stress redistribution and material weakening in olivine.

A Landau–Kolmogorov inequality for Orlicz spaces
In this paper we prove that the Landau–Kolmogorov inequality for functions on the half line holds for any Orlicz space with the constants, which are best possible for -space.

Undergraduate nursing students challenge misconceptions towards men in nursing: A mixed‐method study
Abstract Aims To examine misconceptions towards men in nursing from the perspective of undergraduate nursing students. Specifically, this study sought to explore contributing factors of misconceptions and attributions of the success of men in nursing. Design A convergent parallel mixed‐method study.
