ESTIMATION OF HETEROGENEOUS PANEL DATA MODELS WITH AN APPLICATION TO PROGRAM EVALUATION

This article studies panel data models with two-dimensional unobserved slope heterogeneity and interactive fixed effects. We propose a two-step approach to estimate the parameters in the model. We apply the proposed model to estimate heterogeneous treatment effects at both indivi...

Triggering high-energy orbits in rotational nonlinear energy harvesters via time-varying external excitation and internal parameter modulation

The nonlinear dynamics of rotational piezoelectric energy harvesters can enhance power output and broaden the operational bandwidth. However, their practical application is severely constrained by uncontrollable switching between the high-energy orbit (HEO) and low-energy orbit (...

Few-Shot Remote Sensing Scene Classification Leveraging Collaboration of Foundation Models

Foundation models have shown remarkable generalization ability for few-shot learning (FSL). However, their potential for remote sensing scene classification has not been fully explored. Existing methods mainly adapt a single vision–language model and seldom exploit the complement...

Dietary and Nutritional Considerations for Metabolic Dysfunction-Associated Steatotic Liver Disease in Psoriasis and Hidradenitis Suppurativa: A Narrative Review

Metabolic dysfunction-associated steatotic liver disease (MASLD) is increasingly recognised in patients with chronic inflammatory skin disease, particularly psoriasis, for which epidemiological evidence of increased MASLD prevalence is relatively strong; corresponding data in hid...

Methodological quality of systematic reviews on treatments in stroke rehabilitation: A cross‐sectional study

OBJECTIVE: Although high-quality systematic reviews (SRs) could provide reliable evidence on the effectiveness of stroke rehabilitation treatments, methodological flaws may weaken their trustworthiness. This study aimed to evaluate the methodological quality of an up-to-date samp...

Different concentrations of atropine in children with high myopia: a 2-year multicenter double-blind, randomized controlled trial

High myopia in children risks irreversible visual impairment, yet optimal interventions remain debated. This multicenter double-blind, randomized-controlled trial aims to evaluate the effect and safety of different atropine eyedrops for myopia control in children with high myopia...

PatchPorter: LLM-Driven Security Patch Porting via Version Tracing and Context Selection for NPM

Third-Party Libraries are widely used in modern software development, yet their vulnerabilities pose serious security risks. This issue is particularly severe in the NPM ecosystem, where high-risk 1-day vulnerabilities can remain unpatched for extended periods. Although upgrading...

Belobog: Move Language Fuzzing Framework for Real-World Smart Contracts

Move is a resource-oriented programming language designed for secure and verifiable smart contract development and has been widely used in managing billions of digital assets in blockchains, such as Sui and Aptos.Move features a strong static type system and explicit resource sem...

MuMuTestUp: Mutation-Based Multi-agent Test Case Update

Modern software systems evolve rapidly under continuous integration and deployment (CI/CD) practices, in which tests act as critical gatekeepers of software quality. However, when substantial code changes are introduced, existing test cases may become obsolete, leading to compila...

Staged Multi-step UTXO Workflows via Recursive Invariants

Stateless UTXO-style execution validates transactions using local and referenced data, enabling parallel validation and predictable serialized-size/weight accounting. However, multi-step workflows must thread state across outputs, and a prepared next-step transaction may become s...

A multicenter multistate modeling on the natural history of liver decompensation: Longitudinal analysis of 1777 patients.

BACKGROUND: Cirrhosis often remains silent until decompensation, after which survival deteriorates sharply. Contemporary, transition-aware estimates are limited, especially in Asian-predominant cohorts. We analyzed trajectories from compensated advanced chronic liver disease (cAC...

Can FinTech innovate Green Finance? Scrutinising the Platform Ecologies of FinTech for Forest Restoration

Green finance has struggled to make a difference in climate change mitigation.For some, the main limitations lie in scaling and diversifying financial flows and instruments to close the climate funding gap, while for others, green finance is fundamentally flawed as an incumbent-l...

DeepFeature: LLM-Empowered Context-aware Feature Generation for Wearable Biosignals

Biosignals collected from wearable devices are widely utilized in healthcare applications. Machine learning models used in these applications often rely on features extracted from biosignals due to their effectiveness, lower data dimensionality, and wide compatibility across vari...

CRAFT: Exploring Wearable Creative AI on Smart Glasses for Fiction Writing in Real-World Contexts

Creative writing increasingly integrates AI assistance, yet current tools miss in-situ moments when writers draw inspiration from real-world experiences. We envision Context-aware Reality-Fiction Transformation ( CRAFT ), an approach for AI glasses that translates daily experienc...

Intercellular Transfer of CD155 Mediated by Melanoma Extracellular Vesicles Downregulates DNAM-1 Expression on NK Cells

Melanoma is a highly immunogenic cancer, and immunotherapy is the first-line treatment for patients with advanced disease. However, CD155 overexpression in melanoma has been associated with resistance to immunotherapy. Whether CD155 can be transferred from tumour cells via extrac...

Differential prolonged multiomic responses to mRNA and inactivated virus COVID-19 vaccines

Abstract Despite the significant impact of SARS-CoV-2 vaccines in curtailing the spread and severity of COVID-19, comprehensive omics-level understanding of longitudinal host responses remains elusive. We recruited 553 Hong Kong participants receiving two doses of CoronaVac (inac...

Field sampling guidelines for sedimentary ancient DNA (sedaDNA) research in lacustrine and coastal systems: from field collection to laboratory subsampling

Abstract Sedimentary ancient DNA (sedaDNA) has emerged as a powerful proxy for reconstructing past biodiversity and environmental change in lacustrine and coastal systems, yet standardized field guidance remains limited, particularly for researchers working in tropical and coasta...

A Methodological Case Study for Integrating Virtual Reality and 3D Photogrammetry: A Pilot Digital Platform for Exploring Mangrove Environments

ABSTRACT Mangroves are ecologically vital ecosystems that present unique logistical challenges for field‐based environmental education and research due to seasonal tidal fluctuations, difficult muddy terrain, and visitor safety considerations. Balancing sustainable conservation w...

The shifting landscape of assessment in STEM education in the age of generative AI

Abstract This article focuses on the impact of generative AI (GenAI) on assessment in STEM education. Guided by the assessment triangle as a conceptual framework, we take an ecosystems perspective to review the extant STEM education literature and identify how GenAI affects what...

ViT-radiomics fusion for lymph node classification in ultrasound images: a multicenter study

Abstract Background Ultrasound (US) is widely used for assessing lymph node (LN) status, but its diagnostic accuracy remains highly operator dependent. A robust computer-assisted diagnostic model may enhance clinical performance and improve inter-operator and inter-center consist...
