Based on the primitive core system of PDSM (Prime-π Dimension Symmetry Mechanism), this paper systematically constructs a complete ultimate topological welding system of 100 groups of prime-π (π-P) topological coupling nodes, together with a full set of 100 exclusive topological...

Iatrogenic botulism induced by cosmetic injection requiring mechanical ventilation: clinical characteristics and outcomes

Introduction Cosmetic iatrogenic botulism is increasingly reported, but data on severe cases complicated by neuromuscular respiratory failure requiring mechanical ventilation remain limited. This study aims to characterize clinical features, treatment, and outcomes of such cases....

Culturally Responsive Social Work Practice for Youth Substance Use Rehabilitation in Ghana and Nigeria

This study examines how cultural factors shape youth substance use behaviors in Ghana and Nigeria, given that social work practice functions most effectively when aligned with cultural norms, yet professionals currently lack evidence-based capacity to engage clients within these...

Artificial-Lift System Control: A Reduced-Order Transient Model for Real-Time Predictive Control of Electrical Submersible Pump Wells

Unstable well operations, driven by reservoir depletion, high gas–oil ratios, unstable inflow, and surface network interactions, have become a major challenge in modern production — especially in Western Siberian fields — causing flow instabilities and production losses. While nu...

Precisely Timed On‐Demand Droplet Ejection and Collision in Free Space for Controlled Reaction Initiation

Precise initiation and synchronization of chemical reactions in free space remain major challenges for time-resolved studies in structural biology, chemistry, and materials science. Although modern probes provide femtosecond resolution, experimental access to early reaction dynam...

Perception of 'Ubuntu' and Social Cohesion in Post-Conflict Communities in Africa: An Empirical Investigation of Forgiveness and Reintegration

Abstract Post-conflict societies across Africa continue to grapple with the complex challenges of reconciliation, social reintegration, and the restoration of trust among previously divided groups. In response to these challenges, Ubuntu philosophy commonly encapsulated in the ex...

Is PPR Epidemiological Research Addressing Global Eradication Priorities? A Scoping Review (2015–2025)

The PPR Global Research and Expertise Network (GREN) plays a central role in identifying research priorities supporting the Global Peste des Petits Ruminants (PPR) Eradication Programme (GEP). A scoping review of PPR epidemiological research published between 2015 and 2025 was co...

Salivary Cobalt, Nickel, Chromium and Titanium After Fixed Orthodontic Appliance Removal: A 3-Month Pilot Longitudinal Study

Objective: Our objective was to determine the salivary levels of cobalt, nickel, chromium, and titanium ions at the end of fixed orthodontic treatment and during the post-removal period (1 and 3 months after removal of the fixed appliance). Methods: This pilot longitudinal study...

Additively manufactured wake-stabilizing devices with embedded monitoring for vortex-induced vibration suppression in offshore energy structures

Abstract Vortex-induced vibration (VIV) of cylindrical members remains a persistent reliability concern for offshore energy structures, including risers, mooring lines, and subsea pipelines. This work reports an experimental assessment of additively manufactured passive wake-cont...

Measuring healthcare quality in police custody: the development of quality indicators through expert consultations in the Netherlands

Abstract Background Improving the quality of care for people detained in police custody requires careful measurement and monitoring. However, a standardized and endorsed set of quality indicators for healthcare in police custody settings is lacking. This study aimed to develop a...

A Review on Image Steganography Techniques: Evolution from Classical to Adaptive Methods

Image steganography is an information-hiding technique, aiming to achieve confidentiality and data privacy while transmitting the data in a digital environment. Over the last two decades, steganography has evolved from classical spatial domain embedding to intelligent and adaptiv...

YOLOv8-EMA-P2: An Enhanced Deep Learning Framework for Wheat Grain Detection and Counting from Single-Spike Images

The number of grains per spike is a critical determinant of wheat yield and plays an important role in phenotyping, breeding evaluation, and yield-related trait analysis. However, conventional grain counting methods rely on manual operation, which is time-consuming, labor-intensi...
