Rethinking transformative tourism: transcendence as the reconfiguration of self-world relations

Purpose Transformative tourism research has expanded rapidly, yet “transformation” remains conceptually diffuse and often conflates different depths of experiential change. This article reassesses how transformation has been theorized and advances a transcendent account of higher...

CFD investigation of enhanced heat transfer using periodically spherical-expanded tube

Passive heat transfer enhancement can improve heat exchanger performance without additional energy consumption. This study numerically investigates the heat transfer, flow characteristics, and thermal-hydraulic performance of a periodically spherical-expanded tube under turbulent...

Generative AI in Global Marketing for Sustainability: A Systematic Review of Creativity, Cultural Adaptation, and Governance

Generative AI (GenAI) has emerged in global marketing amid intensifying sustainability regulation and scrutiny. Yet the same generative capabilities that can support the detection of greenwashing may also facilitate its production and dissemination. This systematic review examine...

Rigidity and symmetry breaking in a Serrin problem with a radial variable exponent

We study Serrin's overdetermined torsion problem for the $p(|x|)$-Laplacian in bounded domains containing the origin. An explicit radial solution has flux $-x/n$ and gradient modulus $f(r)=(r/n)^{1/(p(r)-1)}$. Comparison with this solution yields two-sided boundary-gradient bound...

Psychometric validation of the Vietnamese Hospital Anxiety and Depression Scale (HADS) in adults with type 2 diabetes mellitus: a multi-site cross-sectional study

Anxiety and depression are common in type 2 diabetes mellitus (T2DM) and are associated with poorer self-management and clinical outcomes. This study evaluated the measurement properties of the Vietnamese Hospital Anxiety and Depression Scale (HADS) in adults with T2DM. In this m...

Data-Driven Identification of GelMA Hydrogel Formulations with Bioink-Relevant Properties Using Design of Experiments (DoE) and Machine Learning (ML)

Abstract Gelatin methacryloyl (GelMA) hydrogels are promising bioink candidates for extrusion-based 3D bioprinting, but their synthesis and formulation conditions must be optimized to achieve suitable gelation, printability, and mechanical stability. In our study, a design-of-exp...

Insertion into Donor–Acceptor Cyclopropanes with Carbon–Sulfur Moieties Derived from Sulfoxonium Ylides and Elemental Sulfur

Abstract The (3 + 2) cycloaddition of donor–acceptor cyclopropanes (DACs) with carbon–sulfur 2π components has become an emerging method to rapidly assemble tetrahydrothiophenes. Starting materials donating the carbon–sulfur unit are often isolated from thionation of carbonyls or...

Future Exchange Pressure Risk Score (FEPR): Predicting Exchange Market Pressure in Emerging Economies

Emerging economies remain vulnerable to abrupt exchange rate depreciation and reserve losses, creating a need for early warning tools that distinguish current pressure from vulnerabilities that may precede future stress. This study developed the Future Exchange Pressure Risk Scor...

A Low-Power PicoRV32-Based SoC with an Integrated Hardware Accelerator for Real-Time ECG R-Peak Anomaly Detection in 180-nm CMOS

Continuous electrocardiogram (ECG) monitoring in wearable biomedical devices requires processing architectures that balance computational simplicity with hardware efficiency. This paper presents a compact, silicon-proven System-on-Chip (SoC) integrating a PicoRV32 (RV32I) RISC-V...

Selective Clock-Gene Responses to Photoperiodic and Glucocorticoid Exposure in Human Umbilical Cord-Derived Mesenchymal Stem Cells

Objective: Circadian rhythms regulate essential cellular functions, yet their presence and entrainment in human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) remain poorly defined.Methods: hUC-MSCs were cultured under 12-hour light/12-hour dark (light-dark [LD]) cycles...

Evaluating operational efficiency and hydrogen sulfide mitigation in fluidized bed co-gasification of sewage sludge

This study investigated the operational efficiency and in situ H 2 S mitigation of municipal sludge (MS) co-gasification with drinking water treatment sludge (DWTS) in a lab-scale fluidized-bed reactor. Gasification experiments were performed at 700–900 °C, ER 0.2–0.4, and 10–20...

ContractShield: Bridging semantic-structural gaps via hierarchical cross-modal fusion for multi-label vulnerability detection in obfuscated smart contracts

Smart contracts are increasingly targeted by adversaries employing obfuscation techniques such as bogus code injection and control-flow manipulation to evade vulnerability detection. Existing multimodal methods often process semantic, temporal, and structural features in isolatio...

The influence of common good human resource management on employee retention in the United States from motivational and personality perspectives

Retaining employees remains a persistent challenge for organizations, and conventional human resource management frameworks typically address it through economic exchange, leaving open the question of how HR systems oriented toward the common good relate to employees' internal mo...

Sustainable seaweed aquaculture development in the Mekong Delta under climate change

This structured narrative review synthesizes current knowledge on the development of seaweed aquaculture in the Mekong Delta under climate change. Literature searches were conducted through 30 June 2026 using Scopus, Web of Science, and Google Scholar, followed by screening and t...

Higher-order phase-field isogeometric analysis for homogenization of porous media: A multi-patch comparative framework

Computational homogenization of porous media is often hindered by the complexity of mesh generation. While isogeometric analysis (IGA) mitigates geometric errors, multi-patch parameterization for internal voids remains cumbersome. This paper introduces a single-patch, higher-orde...

Selection of acid sulfate purple nonsulfur bacteria for mitigating methane emissions from paddy soils in the Mekong Delta, Vietnam

Abstract In lowland rice cultivation, climate change is increasingly intensified by rising greenhouse gas emissions, especially methane (CH 4 ). This study aimed to: (i) isolate and select acid sulfate-tolerant purple nonsulfur bacteria (PNSB) capable of nutrient provision; and (...

Human–AI Interaction and Work Transformation: Insights From Tourism Professionals

This study examines how generative AI (GenAI) is reshaping tourism work through tourism professionals’ experiences. Drawing on semi-structured interviews supplemented by contextual fieldnotes with 18 workers across tour guiding, travel consulting, customer service, and tour desig...

Greedy and biased algorithms in AI recommendation systems: effects on emotional arousal and impulsive buying

Purpose This study aims to examine the influence of greedy and biased recommendation algorithms on consumers’ emotional arousal, impulsive buying behavior and post-purchase dissonance in artificial intelligence (AI)-driven short video platforms, such as TikTok, Instagram Reels an...

Linking eco-design and digital competence for better social performance with moderation of integrated construction supply chain

Purpose This study aims to investigate the impacts of eco-design (EDS) and integrated supply chain (ISC) on social performance (SPF), the mediating role of EDS in the linkage of digital competence (DC) and SPF and the moderating role of ISC in the EDS-SPF relationship in construc...

Calderón-Zygmund gradient estimates for p-Laplace systems with BMO complex coefficients

This work is concerned with global gradient bounds for a class of divergence-form degenerate elliptic systems with complex-valued coefficients. Notably, the leading coefficients are merely required to be sufficiently small in BMO, which is strictly weaker than the VMO condition....
