Cross‐Entropy of Power Spectral Density Function: A Modal Identification Framework

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT The power spectral density (PSD) function of measured structural response contains a significant amount of information, including the modal parameters (natural frequencies, damping ratios). Output‐only system identification or modal identification technique can be used for extracting such modal parameters from the measured response or its ...

Incidental Detection of Portal Venous Gas During POCUS in a Neonate With Necrotizing Enterocolitis and Intestinal Perforation: A Case Report

Journal of Clinical Ultrasound, EarlyView.
Point‐of‐care ultrasound performed at the bedside identified hepatic portal venous gas in a critically ill neonate, prompting urgent evaluation and revealing intestinal perforation due to necrotizing enterocolitis. This case highlights the potential of POCUS to accelerate diagnosis when clinical signs are subtle or nonspecific.
