3D Microfluidic Networks Formed by Mechanically Guided Compressive Buckling for Large‐Scale Perfused Tissue Culture

ABSTRACT Engineered tissues and organoids offer transformative potential for drug screening and regenerative medicine, yet their application is constrained by limited size and slow maturation. Despite the development of various channel networks for large‐scale engineered tissue p...

Towards a structure-aware multi-hop retrieval framework for large language model reasoning over complex oncology guidelines

Large language models (LLMs) augmented with clinical guidelines show promise in medical question answering, yet structural parsing and evidence retrieval over complex guidelines remain challenging. We propose SMART-RAG (Structure-aware Multi-hop Augmented Retrieval Technique for...

From views to value: investigating YouTube as a tool for academic support among undergraduate students

Purpose The purpose of this study is to examine the use of YouTube as an academic learning resource among undergraduate students and to assess their perceptions, usage behavior and the challenges they face while using the platform for academic purposes. Design/methodology/approac...

Fostering Attitudes and Communicative Self-Efficacy Through Structured Group Discussions on Environmental Socioscientific Issues

Group discussions enable argumentative development and are considered as a core strategy for addressing socioscientific issues (SSIs). Yet, in SSIs, students often struggle to navigate the decision-making process. This has increased interest in scaffolds that make both the proces...

HIV-1 hijacks HGF/c-MET signaling to promote viral entry and replication in primary CD4 + T cells

ABSTRACT The mesenchymal-epithelial transition factor (c-MET) is a receptor tyrosine kinase best known for mediating hepatocyte growth factor (HGF) signaling in cancer, but its role in HIV-1 infection has remained unclear. Here, we identify c-MET as a host factor that promotes HI...

MIRAGE: manipulation-immune RAG with adaptive guard against textual evidence attacks

Abstract Retrieval-augmented generation (RAG) substantially improves large language models (LLMs) on knowledge-intensive tasks by incorporating external knowledge, yet open knowledge sources introduce prominent security risks. The SafeRAG benchmark identifies four novel textual e...

Air purifier performance in an occupied office: Field CADR and effectiveness from a reconstructed device-off condition

Air-purifier performance in an occupied building is hard to assess because the indoor concentration without the device cannot be observed under the same conditions. This study reconstructs that device-off condition from long-term field measurements in an occupied office. Two sequ...

Energy Dependence and Comparative Analysis of D–T and D–D Fusion Cross Sections

This work presents a comparative analysis of the energy dependence of deuterium–tritium (D–T) and deuterium–deuterium (D–D) fusion cross sections using published experimental data. The D–T cross-section measurements are compared with the Bosch–Hale parameterization, and the relat...

Impact of Homoeopathic Similimum in the Treatment of Eosinophilic Bronchitis

Abstract Background: Eosinophilic Bronchitis (EB) is defined as airway inflammation with mildly productive cough and an excess of eosinophil count. The patient shows normal lung function test. The sputum analysis shows increased eosinophil count. EB is one of the most common caus...

A putative nursery pollination mutualism between Japanese Chrysosplenium plants and Nipponorhynchus sawflies

Societal Impact Statement Understanding ecological interactions is increasingly important for biodiversity conservation. This study reveals a unique nursery pollination mutualism between Japanese endemic plants and sawflies. These partners exhibit tightly synchronized life cycles...

Economic Systems: Objectives, Dynamics, and Institutional Design

Economic activity is an evolving organization of households, enterprises, productive capabilities, financial commitments, institutional rules and expectations. We argue that an integrated economic framework should connect three questions: what conditions of human life should deve...

Topography-Driven Liquid Repellency in PFAS-Free Spherical-Particle Coating

Abstract The development of PFAS-free (per- and polyfluoroalkyl substances), liquid-repellent surfaces require a fundamental understanding of how surface geometry governs wetting-state stability. However, the independent role of interparticle spacing remains poorly understood bec...

Anomalous Transport in Fracture Networks under Shear-Thinning Flow

Seminar given at IDAEA-CSIC, Barcelona. Shear-thinning fluids are injected into fractured rock by design, in drilling and fracturing operations, in enhanced oil recovery, in remediation and in enhanced geothermal systems. This talk asks whether the rheology changes only how much...

From office to living room: linking AI awareness and career sustainability from a work–family boundary perspective

Purpose Drawing upon work–family boundary theory and the significance of employees career sustainability amid widespread artificial intelligence (AI) adoption, this study examines the impact of AI awareness on two indicators of career sustainability (i.e. well-being and productiv...

Teaching peace at school: The case of Diversity School in the Midwestern United States

This qualitative study examines a case of three peace educators in a progressive alternative school in the Midwestern United States. In doing so, the study aims to scrutinize the commitments of the school making possible peace education practices these practitioners employ. Drawi...

Sex work or male-with-male sexual activity and the risks of HIV and hepatitis C acquisition among people who inject drugs: a global systematic review and meta-analysis

Background People who inject drugs (PWID) may engage in sexual behaviours that increase their HIV and hepatitis C virus (HCV) risk, including sex work and male-with-male sexual activity. We undertook a global systematic review to assess whether PWID who engage in these behaviours...

Coupling mechanism of internal polarization evolution and 3D thermal behavior in lithium-ion batteries under high-rate discharge

The spatial heterogeneity of multi-physics fields induced by high-rate discharge affects the safety performance of large-format lithium-ion batteries (LIBs). In this work, Quasi-4D electrochemical-thermal (ECT) coupled model is developed for lithium-ion battery to analyze the spa...

An improved physics-informed neural network for valuing American lookback options under regime-switching jump-diffusion models

This study addresses the computational challenges inherent in valuing American lookback options within a regime-switching jump-diffusion (RSJD) framework. We first formulate the pricing problem as a system of coupled partial integro-differential equations (PIDEs) structured as li...

Effect of seawater on the reactivity, microstructure, and strength of Roman-inspired lime-pozzolan binders

Roman marine concretes were frequently produced using seawater, yet the influence of seawater on lime-pozzolan reactions remains poorly quantified. In this work, pastes and mortars prepared with slaked lime and a natural pozzolan from the Phlegraean Fields were mixed with either...

Adult intestinal malrotation: A rare incidental finding in trauma imaging

Intestinal malrotation is a congenital anomaly resulting from abnormal rotation and fixation of the midgut during embryonic development. It is typically diagnosed in infancy, and its detection in adults—particularly in asymptomatic individuals—is rare. In adults, clinical present...
