IEN-CsF1 accuracy evaluation and two-way frequency comparison.

IEEE Trans Ultrason Ferroelectr Freq Control

Istituto Elettrotecnico Nazionale, G Ferraris, Torino, Italy.

Published: October 2004

In this paper we report the accuracy evaluation of the Italian primary frequency standard IEN-CsF1. We discuss the shifts the frequency standard is corrected for and the procedure used for the accuracy evaluation. In the last section we report frequency comparisons of our fountain with those of remote laboratories and with International Atomic Time.

Background: Patients undergoing liver transplantation (LT) are at risk of perioperative neurocognitive dysfunction (PND), which significantly affects the patients' prognosis.

Objective: This study used machine learning (ML) algorithms with an aim to extract critical predictors and develop an ML model to predict PND among LT recipients.

Methods: In this retrospective study, data from 958 patients who underwent LT between January 2015 and January 2020 were extracted from the Third Affiliated Hospital of Sun Yat-sen University.

This study evaluates the dosimetric impact of arc simulation angular resolution in VMAT-based Single Isocentre Multiple Target (SIMT) SRS, focusing on their dependence on target size, isocentre distance, number of arcs, and arc type. A phantom study analysed angular resolution (0.5°, 1°, 2°) effects on dosimetric accuracy for PTVs of 0.

Objectives: Renal cell carcinoma (RCC) with extrarenal fat (perinephric or renal sinus fat) invasion is the main evidence for the T3a stage. Currently, computed tomography (CT) is still the primary modality for staging RCC. This study aims to determine the diagnostic performance of CT in RCC patients with extrarenal fat invasion.

Innovative nomogram approach to enhance the prediction of Helicobacter pylori infection in children via magnetic-controlled capsule endoscopy.

Eur J Pediatr

January 2025

Department of Digestive Endoscopy Center, School of Medicine, Shanghai Children's Hospital, Shanghai Jiao Tong University, Shanghai, 200062, China.

Unlabelled: Early detection and intervention are crucial in managing Helicobacter pylori (HP) infections, which are associated with various gastrointestinal diseases in children. The traditional Kyoto gastritis scoring system, though effective, requires adaptation for non-invasive techniques like magnetic-controlled capsule endoscopy to enhance early diagnosis and improve patient comfort. This retrospective study involved 474 pediatric patients who underwent magnetic-controlled capsule endoscopy coupled with a C urea breath test at the Children's Hospital affiliated with Shanghai Jiao Tong University School of Medicine from January to December 2023.

Background: The large language model ChatGPT can now accept image input with the GPT4-vision (GPT4V) version. We aimed to compare the performance of GPT4V to pretrained U-Net and vision transformer (ViT) models for the identification of the progression of multiple sclerosis (MS) on magnetic resonance imaging (MRI).

Methods: Paired coregistered MR images with and without progression were provided as input to ChatGPT4V in a zero-shot experiment to identify radiologic progression.
