Anomalous Glassy Thermal Conductivity in a Perovskite Bismuthate Induced by Structural Dynamic Instability

Advanced Science, EarlyView.
Unraveling the underlying mechanisms at the origin of ultra‐low thermal conductivity in pristine crystals is of central relevance to designing new functional materials. Single crystals of the candidate functional material BaBiO3 show an anomalous glassy thermal conductivity, which reveals the role of strong anharmonicity and additional scattering ...

Generalized Phase Tailoring of Arbitrary Orthogonal Polarizations in Meta‐Structure with High‐Order Geometric Symmetry

Advanced Science, EarlyView.
A generalized methodology is proposed for Cm (m ≥ 3) meta‐structures to achieve independent phase control of arbitrary orthogonal polarizations. By integrating orientation tuning with structural tailoring, this approach extends spin‐based designs to polarization‐diverse wavefront engineering, enabling multi‐functional and high‐efficiency meta‐devices ...

On the asymptotic behavior of odd operators [PDF]

Journal of Mathematical Analysis and Applications, 2011
AbstractWe give quantitative versions of strong convergence results due to Baillon, Bruck and Reich for iterations of nonexpansive odd (and more general) operators in uniformly convex Banach spaces.

Quantum Thermalization Dynamics of Fermi Gases Quenched to the BEC‐BCS Crossover

Advanced Science, EarlyView.
This study, reporting the first experimental realization of interaction quench far faster than the Fermi timescale in fermionic many‐body systems, explores real‐time quantum thermalization dynamics in the BEC‐BCS crossover. It observes prethermal states with distinct lifetimes after quantum quench, uncovers universal prethermal scaling, and observes ...

Are veterinary drug maximum residue limits protectionist? International evidence

Applied Economic Perspectives and Policy, EarlyView.
Abstract We analyze the distribution of maximum residue limits (MRLs) on veterinary drugs used in animal production and aquaculture in a global context of food consumption and trade. We compare MRLs by drug‐product pairs for a large set of countries, commodities, and drugs.

Principal spectral theory and asymptotic behavior of the spectral bound for partially degenerate nonlocal dispersal systems

Advanced Nonlinear Studies
The purpose of this paper is to investigate the principal spectral theory and asymptotic behavior of the spectral bound for cooperative nonlocal dispersal systems, specifically focusing on the case where partial diffusion coefficients are zero, referred ...

Asymptotic behavior of Szegö polynomials

Journal of Computational and Applied Mathematics, 2005
AbstractA way of finding the unknown frequencies in a trigonometric signal is based upon the use of a certain family of measures on the unit circle, constructed from observations of the signal. The measure gives rise to an inner product, moments and orthogonal polynomials; Szegö polynomials.
