DeMa: dual-path delay-aware Mamba for efficient multivariate time series analysis

Abstract Accurate and efficient multivariate time series (MTS) analysis is increasingly critical for a wide range of intelligent applications, including traffic forecasting, anomaly detection for industrial maintenance, and trajectory classification for health monitoring. Within...

Bidirectional optoelectronic switching in protein by photoinduced phase transition

Protein polymers conduct electricity due to the delocalization of π electrons along the conjugated main chains, but their photoconductivity often shows unidirectional tunability. We report a protein polymer with bidirectional optoelectronic conductivity because of reversible ligh...

Framing hotel strategies for demand uncertainty: The asymmetric effects of cancellation policies and F&B incentives

This study examines how hotels manage demand uncertainty through two contrasting strategies: cancellation policies as loss-framed uncertainty reduction tools and food and beverage incentives as gain-framed coping mechanisms. Drawing on prospect theory, we argue that these approac...

Joint capacity planning and dynamic allocation for container leasing with asymmetric substitution

Container leasing companies maintain a flexible container pool to meet short-term requests from committed customers and the spot market. However, capacity planning and container allocation are complicated by stochastic demand, container returns, and asymmetric substitution betwee...

A source–medium–receiver framework for modeling wind-driven vegetation cooling in urban landscapes

Vegetation cooling in cities is often represented as a local, isotropic effect, although atmospheric processes can redistribute cooling beyond individual vegetation patches. This simplification may overlook the nonlocal and directionally structured nature of cooling propagation....

A fast prediction approach for airfoil flow field based on the deep neural network framework

A rapid aerodynamic prediction framework, termed ParaAero-Net, is proposed for low-Mach-number two-dimensional airfoils under small-sample conditions. Unlike conventional data-driven approaches that focus only on either flow-field reconstruction or aerodynamic coefficient predict...

Live-streaming strategy choices for online retail platforms: external recruitment versus internal cultivation?

Purpose Live-streaming sales have emerged as a pivotal strategy for manufacturers to expand market reach and enhance brand influence. However, some manufacturers hire their own staff to conduct live sales, while others outsource to third-party streamers. Our purpose is to address...

Carbon dot/rare-earth compound composites: design principles, synthetic strategies, mechanisms, and applications

The integration of carbon dots (CDs) with rare-earth compounds (RE-compounds) has emerged as an important strategy for constructing multifunctional photofunctional systems capable of overcoming the intrinsic limitations of single-component luminescent materials. Owing to their br...

The Topicalization Comparative Construction—Evidence from Sinitic and Beyond

In this paper, we discuss topicalization comparatives, an underrecognized subtype within the Heinean event-schema framework. Drawing on data from Nyanja, Malay, and Sinitic languages, the analysis corroborates the existence of a construction marked by a fronted topic with an obli...

Predicting the future of battery lifetime and knee point ultra-early at the formation stage

Early lifetime prediction can accelerate lithium-ion battery development, support factory-side quality control, and reduce testing-related energy consumption. However, most existing methods rely on post-production cycling data and long test windows, limiting manufacturing scalabi...

Tunnel face extraction method for drill-and-blast tunnels considering occlusion and blur degradation

Reliable extraction of tunnel-face regions is essential for image-based rock-mass interpretation and intelligent construction control in drill-and-blast tunnels. However, field images are often degraded by machinery and worker occlusions, invalid backgrounds, uneven illumination,...

Single-ended fault location method for multi-terminal overhead-cable hybrid transmission line using alternating search algorithm

With rapid urbanization and power grid expansion, multi-terminal overhead-cable hybrid transmission lines have been increasingly utilized. However, the significant differences between overhead lines and cables, combined with the complexity of multi-terminal structures, lead to co...

Mechanistic analysis of silver leaching from c-Si solar cells using an acetamide-based deep eutectic solvent

An efficient medium for silver (Ag) recovery from end-of-life crystalline silicon (c-Si) solar cells should combine strong Ag reactivity with limited co-extraction of non-target metals and good reusability. In this study, an acetamide-based deep eutectic solvent (DES) composed of...

Supercritical autoignition of methane in an ultra-high-pressure rapid compression machine at up to 160 bar: real-fluid effects and two-stage ignition behavior

Although methane autoignition under ultra-high-pressure and supercritical conditions is highly relevant to advanced high-pressure combustion systems, such conditions have rarely been studied in RCMs. In this work, supercritical methane ignition is investigated in a newly establis...

Towards Collaborative Autonomous Operations in Power Infrastructure: A Robotic Fine Manipulation Framework

Gas-insulated substations (GISs) have been widely adopted in modern power systems due to their compact design and high reliability. However, the potential generation of toxic byproducts poses significant risks to manual operations such as gas pressure adjustments, highlighting th...

Primary Care Quality and Revisit Intention Among Hong Kong Older Adults: A Cross-Sectional Study

Background: The healthcare system of Hong Kong is facing a growing burden arising from chronic diseases and patient demands because of the rapid ageing and healthcare workforce shortage. Primary care is widely recognised as the most cost-effective way in improving health of the p...

Hippocampal contributions to reading processes

Abstract The cortical substrates of typical reading have been extensively investigated. However, the functional contributions of subcortical regions to reading remain poorly understood and are largely absent from current neuroanatomical models. In the present fMRI study, we analy...

Dynamics-aware hierarchical decision–control with egocentric perception for robust navigation of underactuated uncrewed surface vehicles

Reliable navigation of underactuated uncrewed surface vehicles (USVs) in complex waters depends on the consistency between adaptive decision-making and physically executable motion under nonlinear dynamics and environmental disturbances. Existing deep reinforcement learning metho...

Music-Based Program for Emotion Regulation in Hong Kong: A Randomized Controlled Trial

Purpose Despite the prevalence of emotion regulation difficulties among young people, there are limited evidence-based brief programs that are effective and acceptable to this population in the community setting. This randomized controlled trial examined the effectiveness and acc...

Early transmission risks of Ebola disease outbreak caused by Bundibugyo virus in the Democratic Republic of the Congo

An outbreak of Ebola disease caused by Bundibugyo virus (BDBV) has been ongoing since April 2026, primarily in the Democratic Republic of the Congo. We estimated the initial reproduction number of BDBV at 1.85 (95% CrI: 1.09, 3.25), underscoring the urgent need for timely impleme...
