Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Patients with chronic kidney disease undergoing hemodialysis commonly experience reduced physical function, fatigue, poor sleep quality, and impaired health‐related quality of life. Intradialytic exercise has been proposed as a non‐pharmacological strategy to improve these outcomes.

Time-Varying Currency Betas: Evidence from Developed and Emerging Markets [PDF]
This paper examines the conditional time-varying currency betas from five developed markets and four emerging markets. A trivariate BEKK-GARCH-in-mean model is used to estimate the timevarying conditional variance and covariance of returns of stock index,

Design and Validation of Measurement Procedures for Time-Varying Scatterers and Antennas [PDF]
, 2022 There is an interest in establishing performance metrics for time-varying antennas. However, quantifying the realized performance of a time-varying antenna requires considerations not necessary in LTI measurements as many metrics and electromagnetic ...

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 ...

Learning and Time-Varying Macroeconomic Volatility [PDF]
This paper presents a DSGE model in which agents' learning about the economy can endogenously generate time-varying macroeconomic volatility. Economic agents use simple models to form expectations and need to learn the relevant parameters.

Stabilization of linear continuous time-varying systems with state delays in Hilbert spaces
Electronic Journal of Differential Equations, 2001 This paper studies the stabilization of the infinite-dimensional linear time-varying system with state delays $$dot x = A(t)x + A_1(t)x(t-h)+B(t)u,.$$ The operator $A(t)$ is assumed to be the generator of a strong evolution operator.
