Effect of Omani Limestone Waste as a Reinforcing Agent on the Mechanical Properties of Scrap-Based Aluminum Matrix Composites

This paper analyzes the use of Omani limestone, collected from the mountain ranges of the Sultanate of Oman, a major global exporter of limestone, as a natural reinforcement to improve the mechanical properties of recycled aluminum alloys obtained from automotive engine cylinder...

A multilevel analysis of the predictive effects of internal migration and region of residence on women’s empowerment in Nigeria

BACKGROUND: Despite growing research interest on the influences of migration and regions of residence on human behaviors, studies on the influences of migration and region of residence on women empowerment especially in sub-Saharan Africa are lacking. Thus, this study investigate...

From Product-Quality Complaints to Patient-Safety Triage: A Structured Narrative Review and Proposed PRCS-TRACE Framework

Product-quality complaints are usually handled as pharmaceutical quality-system events, yet defects in sterility, potency, identity, packaging, labelling, storage, distribution or delivery-device function may affect medication use, treatment continuity and patient outcomes. This...

Shifting AAV9 tropism by binding moiety insertion enhances transduction of tumor cell lines and human glioblastoma explants

Abstract Tumor-specific targeting remains a major obstacle for the development of precision cancer therapies. For several tumors and specifically glioblastoma (GBM), an aggressive brain tumor with poor prognosis, more effective treatments are urgently needed. Recombinant adeno-as...

Leveraging Cognitive States for Adaptive Scaffolding of Understanding in Explanatory Tasks in HRI

Understanding how scaffolding strategies influence human understanding in human-robot interaction is important for developing effective assistive systems. This empirical study examines linguistic scaffolding strategies that rely on negation as a key mechanism for steering users a...

The Moment of Delivery in Online Retailing: How Courier Types and Inoculation Messages Affect Reactions to the Last-Mile Experience

Online customers’ journeys span several touchpoints, which typically do not involve any interpersonal interactions with online retailers—except at the moment of delivery (MoD). When retailers use third-party courier services to fulfill orders, they relinquish control over this cr...

From Perceptrons to Convolutional Neural Networks: A Practical Tutorial on Spatial Deep Learning

This tutorial takes the reader on a historical and technical journey from the simple Perceptron (1958) to modern Convolutional Neural Networks (CNNs) that dominate spatial data processing (images and video). We start with the Perceptron’s linear classifier, then expose its inabil...

Ruling In and Ruling Out Sepsis Using Likelihood Ratios of a Host Response Assay

Overview: SeptiCyte RAPID is an FDA-cleared gene expression test that quantifies host immune response to aid in the diagnosis of sepsis. The test yields a score (the SeptiScore) ranging from 0–15, distributed across four bands (1–4) based on increased likelihood of sepsis. Each b...
