Objectives: The purpose of this study is to evaluate the performance our deep learning algorithm in calculating cardiothoracic ratio (CTR) and thus assessment cardiomegaly or pericardial effusion occurrences on chest radiography (CXR). Methods: From a database 8000 CXRs, 13 folders with comparable number images were created. Then, 1020 chosen randomly, proportion each folder. Afterward, CTR was calculated using RadiAnt Digital Imaging Communications Medicine (DICOM) Viewer software (2023.1)....

3D force sensors were developed to further integration in laparoscopic heads of surgery robots. The Si operate with piezoresistive transduction principle by measuring the stress induced signals symmetrically arranged four piezoresistors a deforming membrane. As chip size has be reduced few mm2, conventional anisotropic alkaline etching technique was replaced deep reactive ion (DRIE) for membrane formation. Moreover, DRIE enables form any geometry and offers formation monolith transfer rod...

Introduction Structural modification of proteins, mainly collagen in connective tissues, is important the manufacture tissue-derived biomaterials. Natural compounds like genipin or tannic acid (TA) have been proposed instead glutaraldehyde which shows cytotoxic effects on processed tissue. Furthermore, calcification glutaraldehyde-treated tissue limits functional lifetime bioprostheses. TA known to form numerous hydrogen bonds with proteins. The purpose our study was investigate structural...
