Topological magnon noises

Abstract We develop a comprehensive formalism for magnon transport in ferromagnetic insulators driven by a temperature gradient. The formulas for magnon current and corresponding magnon noise are derived herein based on the spin Hamiltonian of a topological magnon insulator, whic...

To investigate the modulating effect of cognitive load on emotional conflict-related attentional regulation of social evaluative information in individuals with social anxiety, and to clarify the differences in affective attentional modulation patterns between individuals with so...

Light‐Synergistic Enhanced Synaptic Devices Toward Superadditive In‐Sensor Computing

ABSTRACT Conventional neuromorphic devices face challenges in achieving efficient integration of light sensing and synaptic computation because of structural and material limitations. In this work, we developed an indium‐tin‐zinc oxide/transparent gelatin electrolyte synaptic tra...

Class-monopoly rent and contested retail spaces under financialization: Small businesses, landlord power, and policy interventions in Singapore and Hong Kong

This article examines the contestation over the use of retail spaces between large retail landlords and small retailers in Hong Kong and Singapore. Over the past two decades, a substantial portion of retail properties in both cities has become concentrated under real estate inves...

Defect-Driven TiO2– x /SrTiO3– x Heterostructure with Ferroelectricity Enables Shuttle Suppression and Dendrite-Free Growth

Abstract The inherent Li dendrite growth, notorious shuttle effect, and severe redox reaction kinetics of lithium polysulfides (LiPSs) impede the feasibility of practical development of lithium–sulfur (Li–S) batteries. Herein, a bi-functional defect-rich TiO2–x/SrTiO3–x nanocube,...

Payment reform, remuneration incentives, and changes in service utilization and institutional revenue composition: an interrupted time-series analysis from Sanming, China

Hospital-centred service delivery and underused primary care can reduce health-system efficiency. We examined changes in service utilization, provider distribution, and institutional revenue composition during Sanming’s health reform. We analysed 144 monthly observations from Jan...

Bench-Stable Rh/Chiraphos Catalyzed Asymmetric Hydrogenation Reaction of Citral and Its Mechanistic Studies

Abstract Although the Rh/chiraphos-catalyzed asymmetric hydrogenation of citral is a main industrial route to produce important chiral fragrance monomer l-menthol, this process still suffers from facile deactivation, strong substrate configuration dependence, and sub-optimal enan...

Angular-Momentum Loss and Radiated Lorentz Charge in Kerr Scattering at Quadratic Spin

We present a complete derivation of the radiated Lorentz charge in the scattering of two Kerr black holes at third post-Minkowskian order and quadratic spin. Starting from the leading Kerr waveform, reverse unitarity gives the connected finite-frequency contribution. It includes...

A 3D Metal–Organic Framework Protective Layer with Size-Selective Channels and Zincophilic Sites for Highly Stable Zinc Metal Anodes

Aqueous zinc-ion batteries possess intrinsic operational safety, low cost and scalable application potential, making them promising candidates for large-scale energy storage. However, Zn metal anodes still suffer from severe dendrite proliferation, hydrogen evolution, interfacial...

A Variation of the Morris Constant Term

The Morris constant term identity is important due to its equivalence with the well-known Selberg integral. We find a variation of the Morris constant term, denoted $h_n(t)$, in the study of the Ehrhart polynomial $H_n(t)$ of the $n$-th Birkhoff polytope, which consists of all do...
