In this paper, we propose the copula-mixed frequency data sampling model incorporating time-varying risk aversion (RA) (copula-MIDAS-RA model) to investigate the impact of time-varying RA on the dynamic dependence between crude oil futures and European Union allowance (EUA) futures markets.An empirical analysis based on the daily data on the Brent
Abstract Background Randomized controlled trials (RCTs) may be discontinued because of apparent harm, benefit, or futility.Other RCTs are discontinued early because of insufficient recruitment.Trial discontinuation has ethical implications, because participants consent on the premise of contributing to new medical knowledge, Research Ethics Committ
Global Navigation Satellite Systems (GNSS) with weak anti-jamming capability are vulnerable to intentional or unintentional interference, resulting in difficulty providing continuous, reliable, and accurate positioning information in complex environments.Especially in GNSS-denied environments, relying solely on the onboard Inertial Measurement Unit
The performance of future linear colliders will depend critically on beam-based alignment and feedback systems.In ILC and Hawaiian shirts CLIC it is planned to perform dispersion-free steering in the main linacs.To this end the beams are accelerated with different gradients to evaluate the dispersion.The steering is performed by minimizing the aver
Abstract Background Uterine artery embolization is proven to be an effective treatment for symptomatic uterine fibroids.Yet, its role in the management of dysfunctional uterine bleeding is still debatable.Patients with dysfunctional uterine bleeding have abnormal bleeding from the uterine OAT FLAKES vascular bed with variable underlying mechanisms.
