Urban growth-induced surface thermal dynamics: an integrated deep learning assessment for Colombo, Sri Lanka

Abstract Urban growth is a major driver of land surface temperature (LST) change, yet most LST forecasting studies do not explicitly incorporate future urban expansion. To address this gap, we develop an integrated deep learning (DL) framework that couples urban growth simulation...

Exploring hydrogen production from plastic waste for urban transportation in Hong Kong and its environmental impact mitigation: integrating dynamic material flow analysis and life cycle assessment

Plastic waste to hydrogen technology offers a sustainable clean energy pathway while reducing landfill and incineration burdens. However, its feasibility as a feedstock for urban mobility decarbonization at the city scale remains largely unexplored. Hong Kong, as a densely popula...

Subtype-Specific Efficacy of Adrenoceptor Agonists in Inhibiting Lens-Induced Myopia in Chicks

Abstract Purpose Alpha-adrenergic receptors (ARs) may potentially play a critical role in controlling myopia, with subtype-specific signalling pathways mediating distinct effects. This study systematically investigated the efficacy of three subtype-specific pharmacological agents...

XFlowMap: cross-scale generalization and mapping of massive origin-destination data

Mapping large origin-destination (OD) datasets remains challenging because flow maps become cluttered, meaningful patterns occur at multiple spatial scales, and existing flow-mapping approaches frequently rely on predefined aggregation units or manual generalization. This paper p...

Experimental and numerical investigation into the stripping mechanism of Grade-A marine steel during high-pressure water jet impingement

This study investigated the removal behavior and stripping mechanisms of corrosion products during high-pressure water jet rust removal, using a two-component epoxy coating as a rust-layer substitute. Numerical simulations and impingement experiments under different jet pressures...

Electron‑Sponge S‑Scheme Heterojunctions via Mo–N Bridging Enable Highly Selective Photocatalytic CO 2 Methanation

ABSTRACT The kinetic limitations of multi‐electron transfer present a fundamental challenge to achieve selective CO 2 photoreduction to CH 4 . This work pioneers an interface electron‐flux intensification strategy by constructing a Mo–N‐bridged S‐scheme phosphomolybdic acid (PMA)...

Bimetallic Metal‐Acetylide Frameworks for Highly Selective and Durable H 2 O 2 Electrosynthesis

ABSTRACT Metal‐acetylide frameworks (MAFs) feature tunable d–π orbital hybridization between transition metal centers and π‐ conjugated acetylide linkers. Here we report a two‐dimensional (2D) MAF, ZnTTPP‐Ni‐AF, assembled from zinc‐thienylporphyrin units (ZnTTPP) and nickel(II)‐b...

Antiferrodistortive Matrix Engineering Reprograms Polarization Pathways for Ultrahigh Energy Storage at Moderate Electric Fields

ABSTRACT Relaxor ferroelectrics (RFEs) are promising dielectric materials for pulsed multilayer ceramic capacitors because of their rapid polarization response. However, under practical electric fields, polarization rapidly approaches saturation as polar nanoregions exhaust their...

Utilizing Artificial Intelligence in Personal Health Contexts: Investigating Information Seeking Motivations, Information Processing Behaviors, and Behavioral Responses During and After Interaction with GenAI

Following the advent of generative artificial intelligence (GenAI), seeking health information on GenAI has become a more common and flexible approach. However, laypeople's health information seeking and processing (HISP) motivations and behavior on GenAI platforms remain underex...

Color Matching and Observer Metamerism Across Displays With Narrow‐Band Primaries and Color Gamuts Approaching Rec. 2020

ABSTRACT Color matching functions (CMFs) serve as the fundamental basis for deriving tristimulus values and chromaticities, which are essential for color specification, calibration, and reproduction. With the rapid advancement of display technologies, modern commercial devices in...

Flipped Learning with AI-Enabled Support for CFD Fire Modelling Education: A Student Survey Case Study

With the rapid development of AI technologies, digital software, and teaching methods, flipped-learning approaches are becoming increasingly popular for academic education. Next-generation teaching modules will potentially enhance the learning experiences of students. In this stu...

Public Health and Optimal Trade Policy: The Role of Immigration

ABSTRACT We determine the optimal tariff in the presence of immigration and public health provision in a factor‐abundance‐driven trade model, and we prove two results. First, ceteris paribus , a higher value of immigrant output, a more efficient or cheaper public health service,...

Psychometric properties of the timed backward walk test in people with stroke

OBJECTIVE: To examine the psychometric properties of the Timed Backward Walk test in people with stroke. DESIGN: Cross-sectional study. SUBJECTS: 60 people with stroke and 30 healthy adults aged 55 years and older. METHODS: Participants performed the Timed Backward Walk test and...

Promoting Adolescent Health and Confidence: Novel Seamless Sports Bra Design for Comfort, Biomechanical Support, and Satisfaction

The lack of well-fitting and supportive sports bras is a significant public health barrier, hindering adolescent girls from engaging in physical activity and negatively impacting their physical and mental health. This study aims to optimize sports bra design through seamless cons...

Empowering Drivers as Collaborative Social Agents: Enhancing Pedestrian Interaction through Cooperative Interfaces in Autonomous Vehicle Systems

While autonomous driving technology reduces the operational burden on drivers, it may also diminish their sense of engagement, for example, by interrupting social interactions between drivers and other road users such as pedestrians. To address this, this article proposes a “Soci...

Aero‐breakup of droplets: Recent progress and outlook
