A YAP–TEAD–CTCF Transcriptional Regulatory Axis Associated With the Elimination of Injured Hepatocytes From the Liver

Genes to Cells, Volume 31, Issue 6, November 2026.
Injured YAP‐activated hepatocytes are eliminated from the liver. They are extruded toward the sinusoidal lumen, undergo cell death, and are phagocytosed by macrophages. Here, we performed proximity ligation assay, ATAC‐seq, RNA‐seq, and CellChat analyses.

Excess Liver Fat in Type 2 Diabetes Stratified by Intrapancreatic Fat Deposition: A Meta‐Analysis of Dual‐Organ MRI Studies

Liver International, Volume 46, Issue 11, November 2026.
ABSTRACT Both liver fat content (LFC) and intrapancreatic fat deposition (IPFD) are frequently increased in Type 2 diabetes mellitus (T2DM). We meta‐analysed dual‐organ MRI studies comparing LFC between individuals with T2DM and non‐diabetic controls and explored whether study‐level differences in LFC varied according to IPFD burden. Seventeen studies (

Enhancing Load frequency control in power systems using Puma Optimizer – Proportional Integral Derivative Method [PDF]

Iranian Journal of Electrical and Electronic Engineering
Frequency instability is one of the causes of severe disturbances in the power system, including load shedding and widespread blackouts. Especially in modern power systems, frequency instability has even more serious consequences due to the propagation ...

HYBRID GREY WOLF OPTIMIZATION-PATTERN SEARCH (hGWO-PS) OPTIMIZED 2DOF-PID CONTROLLERS FOR LOAD FREQUENCY CONTROL (LFC) IN INTERCONNECTED THERMAL POWER PLANTS

ICTACT Journal on Soft Computing, 2016
The combination of Grey Wolf Optimization and Pattern Search Technique (hGWO-PS) has been introduced to optimize the parameters of two Degree of Freedom Proportional-Integral-Derivative Controller (2DOF-PID) for controlling the load frequency in Automatic Generation Control (AGC) for interconnected power system. The interconnected two area power system

Load Frequency Control (LFC) Menggunakan Metode Noise-Tolerable PID Feedback pada Power Generation Plant Simulator PLTU PT. Pembangkitan Jawa dan Bali (PJB) Unit Pembangkitan (UP) Paiton

Jurnal Teknik ITS, 2017
Frekuensi sebesar 50 Hz harus dijaga agar memberikan kualitas energi listrik yang baik. Pengaruh dari switching pada sisi beban akan membuat frekuensi energi listrik menjadi fluktuatif. Nilai frekuensi yang fluktuatif akan membuat fungsi derivatif pada kontroler Proportional Integral Derivative (PID) menjadi sangat besar, sehingga akan mempengaruhi ...

Robust LFC design using mixed H2/Hinf technique [PDF]

, 2004
This paper addresses a new decentralized robust control design for load-frequency control (LFC) in multi-area power systems. The LFC problem is considered as a multi-objective problem and formulated via a mixed H2/H∞ control technique, then it is easily ...

Robust adaptation in dynamically switching load frequency control

, 2020
In recent years, heuristics for adaptive solutions to load frequency control (LFC) in power systems have been proposed that include adapting the LFC targets or adapting the participation factor for the resources.

Load Frequency Control in Power Systems via A Sampled-Data Controller [PDF]

, 2018
In modern power systems, load frequency control (LFC) scheme usually operates in the discrete mode, while the most existing LFC schemes are designed in the continuous mode, such that those LFC schemes do not work usually in their best manner in practice.
