Differentiable Bilevel Programming for Stackelberg Congestion Games

In a Stackelberg congestion game (SCG), a leader aims to maximize their own gain by anticipating and manipulating the equilibrium state at which the followers settle by playing a congestion game. Often formulated as bilevel programs, large-scale SCGs are well known for their intr...

Personalized regulatory guidance during online cloze tasks: Performance, emotions, and exploratory self-efficacy differences

This study examined whether personalized regulatory guidance supports students' performance, emotions, motivation, and strategy use during online cloze tasks, and whether problem-solving self-efficacy is associated with variability in students' responses to such guidance. Forty-e...

Biofilm presence and substrate type influence oyster larval settlement and survival

ABSTRACT Marine invertebrates with a bipartite life cycle typically undergo a developmental transition from pelagic larvae to benthic juveniles. The success of this transition largely depends on appropriate habitat and substrate selection, which is crucial for completing metamorp...

Machine Learning Guided Broadleaf‐Inspired Reconfigurable Triboelectric Array for Space‐Efficient Ocean Current Energy Harvesting and Antifouling

ABSTRACT Ocean currents represent a stable source of blue energy. Flag‐type triboelectric nanogenerators (F‐TENGs), which have been widely investigated for harvesting energy from low‐velocity ocean currents, generally rely on bluff body to induce vortex. This dependence limits th...

Machine Learning‐Assisted Prediction and Analysis of Viscosity and Fusion Characteristics for Coal and Biomass Ash

ABSTRACT Coal and biomass are important solid fuels, and the viscosity and fusion temperature of their ash have a significant impact on the stable operation of entrained‐flow gasifiers with liquid slag discharge. In this study, separate machine learning (ML) models were developed...

Development and validation of the HKT-PE(J): A standardized assessment for English learning difficulties

English learning difficulties (ELD) are prevalent among Chinese students learning English as a second language (ESL), yet few standardized assessment measures are available to support early identification and intervention. This study developed and validated the Hong Kong Test of...

A 256-year daily rainfall record reveals multiscale rainy-season variability and emerging hydroclimatic hazard over northern East Asia

Monsoon rainy seasons shape water supply and flood hazard across northern East Asia, but their long-term variability remains poorly understood because few daily rainfall records extend beyond the instrumental era. Here, we reconstruct rainy-season onset, retreat, and duration fro...

Bernoulli amputation

A novel, stochastic approach to amputation, the process of introducing missing values to a complete dataset, is presented. It allows one to construct a wide variety of missingness patterns by only having to specify distributions of missingness indicators as opposed to specifying...

PCSK9 inhibitors usage in South China: A Multi-Center Real-World Study

Proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) are effective for lipid management in high-risk patients with atherosclerotic cardiovascular disease. Their inclusion in China’s National Reimbursement Drug List and the Hong Kong Hospital Authority Drug Formulary...

Information design in cheap talk

Abstract An uninformed sender publicly commits to an informative experiment about an uncertain state, privately observes its outcome, and sends a cheap talk message to a receiver. We provide an algorithm valid for arbitrary state-dependent preferences that will determine the send...

The spatial politics of (neo-)imperial mobility control

What can the study of past imperial practices of mobility control tell us about the present? In this article, we engage with the growing literature that examines how past colonial and imperial practices shape present state strategies of population control, by focusing on the spat...

Nancy J. Cox, PhD: A One Health hero in influenza surveillance

Abstract Background : This program continues to provide human and animal health authorities with information on zoonotic human and swine influenza viruses and infections for their early detection, disease prevention and control, and pandemic preparedness. Aim : The aim is to exam...

Calibration and performance of proANUBIS: A proof-of-concept detector for the ANUBIS experiment

Long-lived particles with lifetimes τ > 10 ps are predicted by many extensions of the Standard Model with viable dark matter candidates. The ANUBIS experiment proposes to extend the experimental sensitivity to long-lived particles by instrumenting the ceiling of the ATLAS cavern...

Dirac‐Point‐Assisted Topological Charge Exchange in Dual‐Wavelength BIC Vortex Microlasers

ABSTRACT On‐chip lasers that emit wavelength‐multiplexed structured light are important in integrated photonics. Bound states in the continuum (BICs) provide high‐quality resonances with radiation topology, enabling vortex lasing at multiple wavelengths. However, the topological...

Representation learning in diffusion and flow-based model: an application aspect

Abstract Diffusion models and flow-based models have recently become the dominant paradigms in generative modeling, largely due to their ability to learn rich, multi-level visual representations through large-scale training. This creates a bidirectional relationship between gener...

A Bijective Image Retargeting Algorithm Based on Conformal Energy

Abstract. Image retargeting, which resizes an image to a prescribed aspect ratio by determining an optimal warping map, has gained substantial interest in imaging science. Despite significant advances, existing methods often fail to ensure bijective warping maps essential for pre...

Navigating equity tensions and enacting agency in Chinese TESOL practicums

This qualitative study examined how 38 preservice TESOL teachers placed in Chinese middle schools identified, navigated, and challenged perceived pedagogical inequities during a brief practicum. Using a critical sociocultural framework, reflective papers ( N = 38) and focus group...

Multivalent antiviral conjugates enhance activity against Influenza via cross-linking viruses

Abstract Long-acting drug–Fc conjugate (CD388) has emerged as a new class of antivirals against influenza A and B, yet the mechanisms governing how Fc conjugation reshapes small-molecule function remain undefined. Here we establish a programmable multivalent antiviral conjugates...

Organizational social capital, professional identity, and cultural exhibition work in academic libraries

Although academic libraries increasingly use exhibitions to support education, cultural engagement, and community outreach, less is known about how staff experience this work and the organizational conditions that shape their participation. This qualitative study examines cultura...

Decentralized Solar-Driven Plant Factories Secure an Adequate Global Vegetable Supply beyond the Electricity Grid and Water Limitations

Abstract Conventional open-field vegetable production is increasingly constrained by climate volatility and natural resource endowments, creating supply instabilities and shortages that threaten global food resilience and human health. Here, we integrate solar photovoltaics and a...
