Comparison of IRI-Plas STEC and IONOLAB-STEC Over a Midlatitude GPS Network

, 2019
Total Electron Content (TEC) is an important parameter of the ionosphere used to investigate and determine the ionospheric variability. Slant Total Electron Content (STEC) is the total number of electrons between the receiver-satellite link ...

Near‐Field Acoustic and Gravity Wave Modes in the Ionosphere Triggered by Ground Motion and Tsunami During the 2024 Mw7.4 Hualien Earthquake

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract The interaction between the atmosphere and other components of the Earth system, such as the solid Earth and the oceans, remains an open and active area of research. In particular, the dynamic response of the ionosphere to forcing from below, such as earthquakes and tsunamis, is not yet fully understood.

Molecular Detection and Antibiotic Susceptibility Pattern of Shiga Toxin Producing Escherichia coli among Children with Diarrhea in Addis Ababa, Gondar, and Harar, Ethiopia

Journal of Medical Microbiology and Infectious Diseases
Introduction: Shiga toxin-producing Escherichia coli (STEC) is a major cause of pediatric diarrhea globally, yet its burden, molecular characteristics, and antibiotic resistance patterns remain underexplored in low-resource settings like Ethiopia ...

A preliminary study of the use of MinION sequencing to specifically detect Shiga toxin-producing Escherichia coli in culture swipes containing multiple serovars of this species

Scientific Reports, 2023
An important challenge relating to clinical diagnostics of the foodborne pathogen Shiga toxin-producing E. coli (STEC), is that PCR-detection of the shiga-toxin gene (stx) in DNA from stool samples can be accompanied by a failure to identify an STEC ...

Multiplex PCR to Diagnose Gastrointestinal Infections: Key Limitations in Interpretation

United European Gastroenterology Journal, Volume 14, Issue 7, September 2026.
ABSTRACT Multiplex polymerase chain reaction (PCR) panels are increasingly used for the evaluation of acute diarrhea, providing rapid and sensitive detection of a broad range of enteric pathogens. However, their widespread adoption has created important interpretive challenges for clinicians.

Identification of Potential Vaccine Strains of Escherichia coli Isolates From Diarrhoeic Calves

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
This study aimed to identify vaccine candidate Escherichia coli strains isolated from diarrheic calves. Faecal samples collected from 500 calves were analysed, and E. coli strains were isolated and characterized phenotypically and genotypically. Antibiotic resistance profiles, virulence‐associated genes and MLVA genotyping were used to select 20 ...

Robust Machine Learning–Based Ionospheric Delay Grid Modeling for PPP‐RTK Under Sparse Reference Stations and Severe Geomagnetic Disturbance

Space Weather, Volume 24, Issue 9, September 2026.
Abstract Sparse reference station networks and severe geomagnetic disturbances can significantly degrade the accuracy of regional ionospheric delay modeling at the network side, thereby reducing the positioning performance of PPP‐RTK. To address this issue, this study proposes a machine learning‐based ionospheric delay grid modeling method that finely ...
