Serum Myonectin Levels Are Positively Associated With Physical Function and Lower Frailty‐Related Limitation in Maintenance Hemodialysis Patients: A Cross‐Sectional Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Maintenance hemodialysis (MHD) patients frequently suffer from frailty, characterized by reduced physical function and poor prognosis. Myokines, such as myonectin, secreted by muscle, are emerging regulators of systemic health. This study investigated the relationship between serum myonectin, adipokines (adiponectin, omentin), and ...

Electromagnetic torque analysis-based method for performance evaluation and optimisation of closed-loop CPS regarding small signal stability

IET Cyber-Physical Systems, 2018
Low frequency oscillation occurs frequently in the smart grid, which threatens the security and stability of the physical system. Wide-area damping controller (WADC), which belongs to cyber system, can effectively ...

Impacts of different wind power generators on power system small signal and transient stability

, 2013
With the ever-increasing penetration level of wind power, the impacts of wind power on the power system are becoming more and more significant. Hence, it is necessary to systematically examine its impacts on the small signal stability and transient ...

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

A Simple Test to Check the Inherent-Stability Proviso on Field-Effect Transistors

IEEE Access, 2018
Available techniques for stability analysis of DC solutions, such as the popular Ohtomo test, make the task quite a straightforward one. Such tests are based on the assumption that the active subcircuit is inherently stable, which is reasonably easy to ...

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

Equivalent circuit model of grid-forming-converter based power grids: Visualizing control loop interactions on synchronization stability

International Journal of Electrical Power & Energy Systems
For grid-forming (GFM) converter-based power grids, the impacts of AC voltage control (ACVC) loops on small-signal synchronization stability are rarely discussed in literature.

A Review of Small Signal Stability Studies of Multi-infeed AC-DC Hybrid System

发电技术, 2023
Multi-infeed AC-DC hybrid system is the notable form of China’s power grid upgraded because of the distribution of the generation and load. Multiple high-capacity high voltage direct current transmission lines enhance the transmission capacity, while the

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Small signal stability analysis of typical power system and its improvement using power system stabilizer

TESEA, Transactions on Energy Systems and Engineering Applications
The modern power network is composed of a huge number of transmission lines and generators. The synchronous generator modelling and its stability analysis are crucial in a power system network.
