Quality‐of‐life and late effects after transabdominal cerclage: A nationwide matched cohort study

INTRODUCTION: A transabdominal cerclage is inserted to prevent recurrent midtrimester loss and spontaneous preterm birth. The transabdominal cerclage often remains as a permanent foreign body for years. Synthetic materials within the abdomen, cesarean birth, and prior adverse pre...

Optimization based on timed Petri nets using CP-SAT - an integrated SAT and CP solver

Abstract A simple but general semantics for timed Petri nets is presented in this paper. Based on this semantics, an optimization formulation is introduced and implemented in a recently developed optimization solver, where a satisfiability (SAT) solver is integrated with constrai...

Why Do Residents Pursue Fellowship Training in Geriatric Medicine?

ABSTRACT Background Despite the important role of Geriatricians in our society, there is a shortage of Geriatric Medicine specialists. This study surveyed fellows enrolled in ACGME approved Geriatric Medicine fellowships in the United States for insight into why they joined a Ger...

Cation-Disordered TbNdFeCoO6 Double Perovskite: Structural, Vibrational, Magnetic, and Electrocatalytic Insights for Efficient Hydrogen Evolution Reaction

Abstract Double perovskite oxides have emerged as promising multifunctional materials for sustainable energy applications due to their tunable structural, electronic, magnetic, and electrocatalytic properties. In this research study, the cation-disordered double perovskite TbNdFe...

Hepatitis B knowledge, attitudes, prevention practices, and associated factors among graduating health sciences students at Bahir Dar University, Ethiopia

Hepatitis B virus infection is a major public health concern with a high contagious rate via blood and body fluids. It is a vaccine-preventable disease. Graduate-level students of health sciences are future healthcare professionals who play a crucial role in the prevention and ma...

Hybrid and transformer based artificial intelligence for diabetic retinopathy diagnosis a systematic review of methods challenges and clinical readiness

Abstract Diabetic retinopathy (DR) remains a leading cause of preventable blindness worldwide, placing a growing burden on healthcare systems. While artificial intelligence (AI) offers promising tools for early detection and scalable screening, its transition from research to rea...

Observational study of people with complete hand amputation using a multigrip myoelectric prosthesis after using a standard myoelectric prosthesis

Background: Clinical evidence substantiating the advantages multi-grip myoelectric hand prosthesis over conventional myoelectric hand prosthesis in daily life remains inconclusive. Objectives: The study aimed to assess the efficacy of using a multi-grip myoelectric hand prosthesi...

Vertical Coherence Dominates Decadal Land Water Storage Change Despite Hydroclimatic Extremes and Groundwater Pumping

Abstract Whether surface and deeper water storage trends move in the same direction underpins assessments of freshwater availability. Theory predicts vertical coherence, yet it is untested globally and questioned under climate extremes and human management. Using depth‐sensitive...

Enzyme-Substrate Interaction by Nuclear Magnetic Resonance

The chemical shifts of the nuclear magnetic resonances of N-acetyl-D-tryptophan are measured and compared to those observed when bound to ∝-chymotrypsin. Chemical shift changes of 1 Hz. are reported for a solution with 1% total substrate bound to the enzyme.

SignBridge v2: An Improved Transformer Architecture for Real-Time Bidirectional ASL Communication

SignBridge v2 is a real-time, bidirectional American Sign Language (ASL) communication platform designed to bridge communication between ASL users and non-signing individuals. The system performs sign-to-text and speech translation using MediaPipe hand landmarks and a custom Tran...

Compatible Seismic Retrofitting of a Traditional Albanian Stone Tower Using Internal Textile-Reinforced Mortar Strengthening

Most of the existing tradition of stone masonry towers is unique and irreplaceable in terms of Albanian traditional vernacular architecture. As most of them are situated in earthquake regions, the performance of unreinforced stone masonry is at risk. The brittleness of the materi...

Techno-Spatial and Economic Assessment of Rooftop Versus Land-Based Photovoltaic Deployment in a Biodiversity-Sensitive Region of the Mexican Caribbean

Solar photovoltaic (PV) expansion in fast-growing tropical regions requires engineering-based frameworks that compare deployment pathways in terms of electricity generation, spatial footprint, and economic performance. This study develops a techno-spatial and economic assessment...

Hyperwave Vibrational Thresholding in E8 Symmetry-Space — E8 Intelligence Research

Exposing latent rotational states in 240 E8 root vectors through localized phi-temporal coupling at 132Hz base resonance. Demonstrates quantized vibrational thresholds where Möbius hypergraph nodes synchronize into N-banded metagraphic lattices under phi-phase perturbation. Confi...

Erdős–Straus Project Archive: Residual Divisor Shells, Quotient Surpluses, and Finite Verification

This record gathers the Erdős–Straus project under its existing concept DOI. The principal paper develops the residual divisor-shell equivalence and its origin counts, proves the Star–Kneser quotient-surplus theorem, and records the exact certificate at p = 12289 with R = 11, m =...

A Multi-Dimensional Digital Twin Framework for the Low-Altitude Economy

Abstract. The Low-Altitude Economy (LAE), driven by the widespread deployment of UAVs and eVTOL aircraft, demands a high-fidelity Digital Twin that extends far beyond static geographic representation. This study presents a critical review of 39 peer-reviewed papers to propose a t...
