Evaluating Well Stimulation in Carbonates: Rapid Skin Factor Prediction Using Machine Learning

ABSTRACT Accurate prediction of the poststimulation skin factor ( S ) is vital for optimizing productivity in carbonate reservoirs. Conventional approaches, such as well‐test analysis, are costly and time‐consuming, limiting their use for real‐time decision‐making. This study int...

Discrepancies in Laboratory Test Results and Their Impact on Patient Confidence in The Health System in Kirkuk, Iraq

The clinical laboratory diagnostic service is the backbone of all medical decisions, but at the health sector the results of laboratory tests for patients are becoming conflicted between various health care sectors in many regions including Kirkuk, Iraq.This diagnostic mismatch j...

Protective efficacy of the Shanchol oral cholera vaccine against cholera in a systematic review and meta-analysis of randomized controlled trials

Oral cholera vaccines (OCVs) have become a crucial part of global strategies for cholera prevention, working alongside water, sanitation, and hygiene (WASH) initiatives. However, estimates of vaccine efficacy can vary depending on the context. This systematic review and meta-anal...

Machine Learning and Deep Learning for Early Disease Detection Across Modalities: A Comprehensive Review of Methods, Applications, and Clinical Translation

Early disease detection is not a single classification problem. It includes population screening, presymptomatic risk estimation, identification of early pathological change, and detection of disease before conventional clinical recognition. Machine learning and deep learning sys...

Predictive modeling of oral squamous cell carcinoma risk using a multi-parametric machine learning framework integrating clinical, sociodemographic, and salivary biomarker data

Abstract Oral Squamous Cell Carcinoma (OSCC) represents a major public health challenge due to diagnostic delays and the invasive nature of conventional biopsy techniques, underscoring the need for accurate, non-invasive prognostic tools. This study develops and validates a multi...

Packed‐bed thermal storage solar air collectors with porous media: Performance influencing parameters and enhancement strategies

Abstract Solar air heaters (SAHs) are promising low‐cost solar thermal systems for heating and drying applications; however, their performance is limited by the low convective heat transfer coefficient between the absorber and the flowing air. Double‐pass configurations incorpora...

A compact 2D photonic crystal biosensor for optical detection of glioblastoma brain tissues enhanced by neural networks

Abstract In this work, a compact optical sensor based on a two-dimensional photonic crystal is proposed for detecting glioblastoma and pre-tumor brain tissues. The sensor uses a hexagonal lattice of silicon rods in air with a ring resonator structure at its center. The designed d...

Comparative analysis of an 80 Gbps radio over fiber system using Duobinary PAM and NRZ Modulation

Abstract Duobinary signal is a sort of advanced electrical modulation that prevents bandwidth limitations of optical fiber signal, through which high data capacity of transmission is achieved. This paper demonstrated a comparison between different formats of duobinary modulations...

Anthrax as a Zoonotic Infection: A "One Health" Perspective and Achieving Sustainable Development Goals

Anthrax is one of the most lethal zoonotic diseases with its ability to persist in the environment for decades and its high mortality rates in humans and animals caused by Bacillus anthracis. This article reviews the pathogen’s life cycle and virulence factors such as the triple...

Biochemical effects of occupational diagnostic ionizing radiation exposure on medical radiographers: AI-assisted exploratory radiation biological effect score (RBES)

Medical radiographers are chronically exposed to low-dose ionizing radiation during diagnostic imaging procedures, raising concerns about the cumulative biological effects of prolonged occupational exposure despite adherence to international radiation protection standards. This c...

Ultrasonic and numerical estimation of thermal management of waste ink powder/epoxy composites

Every year, large toner cartridges are made and used in printers and copiers. Because waste cartridges contain toner powder with a specific chemical composition, they are classified as hazardous waste. As such, recovering waste cartridges is crucial for both waste management and...

Unsupervised Annotation Transfer in Phase-Contrast Microscopy Using a CycleGAN

Domain shift between microscopy imaging domains poses a significant challenge for deploying deep learning-based cell detection models across different experimental setups. Manual annotation of new microscopy datasets remains resource-intensive and time-consuming. This study prese...

Conducting Polymers: Materials, Mechanisms, and Applications – a Review

The 2000 Nobel Prize in Chemistry was awarded to Alan J. Heeger, Alan G. MacDiarmid, and Hideki Shirakawa for the discovery and development of conductive polymers, particularly polyacetylene. Since then, research on conducting polymers has progressed rapidly, with sustained focus...
