Optimized PID controller and model order reduction of reheated turbine for load frequency control using teaching learning-based optimization.

Load frequency control (LFC) systems in power grids face challenges in maintaining stability while managing computational complexity. This research presents an optimized approach combining model order reduction techniques with Teaching Learning-Based Optimization (TLBO) for PID controller tuning in single-area LFC systems. Three reduction methods-Routh Approximation, Balanced Truncation, and Hankel Norm Approximation-were implemented to reduce system order from 4th to 2nd order, achieving a 47.

Solitary Rectal Ulcer Syndrome - A Rare Entity in the Pediatric Population.

Objective: To study and correlate the clinicopathological findings of Solitary Rectal Ulcer Syndrome (SRUS) in 10 pediatric patients.

Material And Methods: This study is a retrospective study of patients from January 2017 to June 2024. The clinical records were reviewed for details of the clinical presentation, colonoscopic findings, associated local and systemic diseases, and other investigations.

Lipid droplet targeting of the lipase co-activator ABHD5 and the fatty liver disease-causing variant PNPLA3 I148M is required to promote liver steatosis.

The storage and release of triacylglycerol (TAG) in lipid droplets (LDs) is regulated by dynamic protein interactions. α/β hydrolase domain-containing protein 5 (ABHD5; also known as CGI-58) is a membrane/LD bound protein that functions as a co-activator of Patatin Like Phospholipase Domain Containing 2 (PNPLA2; also known as Adipose triglyceride lipase, ATGL) the rate-limiting enzyme for TAG hydrolysis. The dysregulation of TAG hydrolysis is involved in various metabolic diseases such as metabolic dysfunction-associated steatotic liver disease (MASLD).

Effectiveness of Three-dimensional Cardiac Computed Tomography Scan in Congenital Heart Surgery-An Impact on Diagnostic Performance and Surgical Management.

Background: Recent advances in gated cardiac contrast-enhanced computed tomography (CECT) with anesthesia support, enhance the imaging performance in congenital heart disease (CHD). 3D reconstruction of the CECT image is a novel modality that could help manage pediatric cardiac patients.

Methods: A retrospective study of children diagnosed with CHD presenting for surgical intervention (n = 139) was carried out at our cardiac surgical center.
