Laparoscopic Burch Colposuspension Versus Transobturator Tape for the Treatment of Stress Urinary Incontinence in Egyptian Women: A 12‐Month Randomized Controlled Trial

AIMS: This study aimed to compare the efficacy, safety, and patient-reported outcomes of laparoscopic Burch colposuspension versus the transobturator tape (TOT) midurethral sling procedure for treating stress urinary incontinence (SUI) in Egyptian women. METHODS: This was a rando...

Neural network-driven adaptive PD controller for hexacopter UAV path tracking

Unmanned Aerial Vehicles (UAVs), particularly hexacopters, have demonstrated remarkable potential for a variety of applications, including military operations, surveillance, precision agriculture and disaster response. However, their deployment is often hindered by challenges ari...

A Multiscale Matrix Framework for Scale Closure, Structural Residuals, and Entropic Rupture in Physical Sectors

This deposit contains the complete manuscript, editable LaTeX source, reproducible Python scripts, generated figures, CSV tables, a local HTML viewer, and verification manifest for a multiscale matrix framework based on closure residuals, sector matrices, kernels, spectral stabil...

Corporate Social Responsibility, Rural Development, and Demographic Sustainability in a Transition Economy

Retaining population is a core condition for the long-term sustainability of rural communities, yet rural out-migration is often treated merely as evidence of local development failure. Agriculturally productive regions may continue to lose population even when output, corporate...

Controversies in the management of fetal growth restriction: a state-of-the-art review

Fetal growth restriction (FGR) affects 5%-10% of pregnancies and remains a major contributor to stillbirth, neonatal morbidity, and long-term adverse outcomes. Despite its clinical importance, substantial controversy persists regarding its definition, diagnostic criteria, surveil...

A Clinically Accessible Nomogram for Identifying Likely Psoriatic Arthritis Among Patients with Psoriasis: A Multicenter Cross-Sectional Study

Background/Objectives: Psoriatic arthritis (PsA) affects up to 30% of psoriasis patients but remains underdiagnosed due to heterogeneous early manifestations. Existing tools rely on advanced imaging or biomarkers, limiting feasibility. This study aimed to develop a simple nomogra...

Phenotypic Analysis of the Anti-T. cruzi Activity of Natural Products Obtained from Brazilian Botanical Sources

Chagas disease, caused by Trypanosoma cruzi (T. cruzi), affects more than 6 million people worldwide, predominantly in Latin America. Current chemotherapy relies on Benznidazole (Bz) and Nifurtimox, which are associated with adverse effects and limited efficacy during chronic inf...

Comparison of Dialysate Calcium Concentrations and Arterial Stiffness in Dialysis Patients: A Network Meta-analysis

Abstract Background Chronic kidney disease often requires hemodialysis, which increases cardiovascular risk, partly because of arterial stiffness. This can be influenced by dialysate calcium concentrations, which affect mineral balance and vascular health. However, there is contr...

Nitinol shape memory alloy (NiTi SMA): additive manufacturing processes in medical devices

Abstract Additive manufacturing (AM) has significantly expanded the design and application of NiTi (Nitinol) alloys in medical devices by enabling the fabrication of complex geometries, fine features, and patient-specific structures that are difficult or impossible to achieve thr...

Near-ideal plug-flow enables stage separation during dry anaerobic digestion of biowaste in a rotating drum fermenter

Conventional designs of anaerobic plug-flow reactors frequently exhibit stagnant zones and pronounced short-circuiting, undermining plug-flow behavior and reliable biowaste pasteurization. Ideal plug-flow conditions could, in contrast, enable a spatial separation of metabolic sta...

The Transmission Mechanism of Monetary Expansion to Corporate Distress: A Case Study of Carvana Co. Under the Post-Pandemic Inflationary Regime

This academic research paper constructs a mathematically rigorous, structurally integrated micro-macro econometric framework designed to isolate and quantify the exact transmission mechanisms through which systemic macroeconomic monetary shocks propagate into corporate capital st...

When trust is not enough: buyer orchestration modes and innovation in coopetitive automotive supply networks

Purpose This study examines how buyer orchestration modes shape knowledge-sharing dynamics and innovation outcomes among competing suppliers in multi-tier automotive supply networks. While prior coopetition research emphasizes trust and voluntary collaboration as drivers of innov...

Generative AI for Hospital Cybersecurity: A Framework for Evaluating Large Language Models for Planning, Threat Detection, and Incident Response

The increasing digitization of healthcare records and growing reliance on interconnected systems have increased hospitals’ exposure to cyber threats, including ransomware, brute-force attacks, and Structured Query Language (SQL) injection. Traditional cybersecurity approaches alo...

Empathic Logic Model (ELM): A Cognitive-Interactional Coherence Framework for Regulating Interpretive Instability

Human meaning-making under uncertainty frequently defaults to premature interpretive closure (PIC). Under emotional activation or cognitive bias, this generates disproportionate emotional reactivity and relational tension. To regulate this instability, the Empathic Logic Model (E...

Liquid-Phase Laser Micro-Dimple Texturing of YG8 Cemented Carbide Tools: Optimization, Wear Mechanism, and Cutting Performance

Cemented carbide is extensively applied in cutting tools. Surface laser micro-texturing alleviates tool surface wear and boosts cutting performance. This work adopts response surface methodology to investigate circular micro-texture parameters (diameter, spacing, offset) of YG8 c...

Which Constant Is Responsible? Dominator Analysis of Classical Dependence in Mathlib

61.2% of Mathlib's theorems depend on Classical.choice. Asking which constant is responsible for that dependence is a different question from asking which constants a proof touches, and the two answers differ by a factor of 58 on the first case examined: 116,766 theorems reach th...

Effects of Hydrochars Derived from Woody Residues on Soil Enzyme Activities and Plant Response

The growing need for biomass waste recycling has led to increased interest in hydrothermal carbonization, which produces hydrochar as a by-product. This carbonaceous material can be applied in agriculture; however, its role in soil health is still not fully understood. Data on th...

Culturable Opportunistic Bacteria and Antimicrobial Susceptibility Patterns in Canine Periodontal Pockets: A Pilot Study

Canine periodontitis is one of the most prevalent chronic diseases for dogs over two years of age. Periodontal pockets may serve as a reservoir for opportunistic bacteria including Pasteurella stomatis, Neisseria animaloris, and Streptococcus canis; however, data on their antimic...

Comprehensive Design and Structural Verification of a Tubular Steel Metal–Hydride Storage Vessel for Hydrogen Separation and Storage

Hydrogen storage and separation remain major technical challenges limiting the broader implementation of hydrogen-based energy systems. Metal–hydride alloys offer a promising solution because they enable reversible hydrogen storage within their crystal structure and can selective...

Impacts of Cold Waves and Urban Heat Islands on Heating Energy Consumption Differences Across Intra-Local Climate Zones

Most studies have explored the impact of different types of local climate zones (LCZs) on energy consumption, but few have examined climate differences within intra-local climate zones (intra-LCZs) and the impact of cold waves (CW) on energy consumption. This study conducted a 15...
