NanostructuredSilver Microparticles from MicrodropletReduction and Evaporative Assembly for Plasmon-Driven Photocatalysisand SERS

Abstract Plasmonic nanoparticle aggregates are excellent plasmonic photocatalysts and substrates for surface-enhanced Raman spectroscopy (SERS) due to localized surface plasmon resonance (LSPR) coupling and hot-spot generation. Yet facile but scalable synthesis methods for such m...

Type 2 Diabetes Mellitus and Chronic Venous Disease of the Lower Extremities: A Narrative Review

Chronic venous disease (CVD) is a highly prevalent but often under-recognized condition, affecting up to 60% of the general population. In patients with diabetes mellitus, the burden of CVD appears to be higher, with more severe clinical manifestations, suggesting shared pathophy...

Cost utility analysis of two BK polyomavirus screening strategies: quantitative polymerase chain reaction vs 2-stage approach

Screening for BK polyomavirus (BKPyV) with quantitative polymerase chain reaction (qPCR) or a 2-stage approach with urine cytology followed by qPCR are acceptable strategies. However, the magnitude of the health benefits and incremental cost of adopting these 2 screening strategi...

Confirmatory Person-Oriented Mediation Analysis in Categorical Variables-Options and Limitations

In this article, we propose three new approaches to analyzing person-oriented mediation hypotheses. First, we propose using relevance logic instead of classical logic. Relevance logic (1) rejects the ex falso sequitur quodlibet ("from a falsehood anything follows") rule and (2) r...

A Computational Study of the Efficiency of Using Low-Concentration Nanoemulsions with Diesel Fuel to Enhance Oil Recovery

The article presents the results of systematic numerical studies on the efficacy of low- concentration nanoemulsions for enhanced oil recovery. A series of computational investigations was conducted to examine the displacement regimes of oil from digital core models with varying...

A Review of Ship Path Planning for Autonomous Navigation: From Model-Driven Methods to Deep Reinforcement Learning

Ship path planning is a central challenge in autonomous navigation for unmanned surface vehicles and maritime autonomous surface ships. It is not simply a shortest-path problem, but a constrained sequential decision process that must reconcile collision risk, route efficiency, CO...

Leprosy control in Sri Lanka after eliminating the disease as a public health problem: implications for elimination of transmission of infectious diseases

Leprosy was eliminated as a public health problem in Sri Lanka in 1995. In 2001, leprosy control activities in Sri Lanka were integrated into the general health services which transferred the duties performed by the dedicated staff of the Anti-Leprosy Campaign to Dermatologists a...

Green synthesis of Cu-Doped ZnO nanoparticles using Syzygium cumini leaf extract and their antimicrobial evaluation

Synthesis of nanoparticles by the green synthesis approach using the plant leaves extract has gained popularity since they are thought to be cost-effective, efficient and environment-friendly. This study was designed to synthesize copper-doped zinc oxide nanoparticles from Syzygi...

Structure–ActivityRelationship in StructurallyDiverse Cobalt Oxide Catalysts for the Electrochemical Reduction ofNitrate to Ammonia

Abstract The electrochemical nitrate reduction reaction (NO3–RR) offers a sustainable method for converting NO3– waste into indispensable ammonia to rebalance the nitrogen cycle, which is considered more severely disturbed than the carbon cycle. Strenuous efforts have already yie...

Combined Fine Needle Cytology and Core Needle Biopsy of the Liver in One Setting: An Experience of 29 Cases

INTRODUCTION: Core needle biopsy (CNB) and fine needle aspiration cytology (FNAC) are routinely used in the diagnosis of hepatic nodules. Despite their advantages, both procedures have certain limitations. Recently, the combined use of FNAC and CNB in the same setting has been ex...

Touching from a distance: toward a common conception of equilibrium in Post Keynesian economics

This paper discusses Victoria Chick’s concepts of provisional equilibrium and long run equilibrium of action. Attention is paid to the relationship between these concepts and other strands of thinking in Post Keynesian theory, as well as the relationship of the two concepts to on...

Clinical practice on treatment of primary traumatic anterior shoulder dislocation: a multidisciplinary guideline

BACKGROUND AND PURPOSE: Primary traumatic anterior shoulder dislocations are common and can have long-term personal implications for quality of life and the use of the arm for occupational activities and sport participation. A patient care pathway has been reported to contribute...

Multimodal graph-based classification of esophageal motility disorders

PURPOSE: Diagnosing esophageal motility disorders, including dysphagia, pose significant challenges due to the complexity of high-resolution impedance manometry (HRIM) data and variability in clinical interpretation. Thiswork explores the feasibility of a multimodal machine learn...

ALD with AlternativeCoreactants: Which Work, WhichDo Not, and Why

Abstract In this work, we present a combined experimental and theoretical study that systematically evaluates a series of alcohols (i.e., primary, secondary, and tertiary) as coreactants for trimethylaluminum (TMA)-based atomic layer deposition (ALD) of Al2O3. We employed in situ...

Graph Attention Reinforcement Learning with Electrical Prior Knowledge for Distribution System Restoration

Distribution system restoration (DSR) has become increasingly challenging due to frequent topology changes and complex nodal interactions, especially in systems with a high penetration of distributed energy resources (DERs). Existing deep reinforcement learning (DRL) methods rema...

Stochastic Gassmann fluid substitution for rapid assessment of hydrogen and carbon dioxide saturations in clastic storage reservoirs.

Safe subsurface storage of carbon dioxide and hydrogen will likely be essential to decarbonising global energy systems. Such storage requires monitoring capable of detecting dynamic changes and unintended migration pathways; seismic methods are expected to form a key component. W...

Diagnostic concordance and delayed recognition: a case of atypical Kaposi sarcoma

OBJECTIVES: Accurate diagnosis depends on concordance among clinical findings, histopathologic features, and patient context; when these elements diverge, even well-characterized diseases may evade timely recognition. CASE PRESENTATION: We report a case of Kaposi sarcoma (KS) in...

XP-IDS: an explainable hybrid CNN–XGBoost framework for IoT intrusion detection

Abstract The rapid growth of IoT-enabled technologies and interconnected smart devices has significantly increased security risks associated with poorly protected and resource-constrained IoT environments. Efficient anomaly detection mechanisms can help mitigate these threats by...

Reconciling nitrogen fertilization effects on soil nitrification with acidification

Nitrogen (N) fertilization supports nearly half of the global population but disrupts the N cycle. While N addition is assumed to stimulate soil nitrification by increasing substrate supply and nitrifier activity, it may also inhibit nitrification via soil acidification. Resolvin...

Some SEN History: Part 2

It is with great sadness that I start out this article by acknowledging the passing of the first editor of SIGSOFT Software Engineering Notes, Peter Neumann. In his honor, what follows is the last Letter from the Editor that Peter wrote for the October 1993 issue of ACM Software...
