Uncertainty Quantification for Nonlinear Vibration of Supercritical Drive Shaft With a Dry Friction Damper

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The supercritical drive shaft is becoming increasingly popular in helicopter transmission system. Dry friction dampers are specially employed to ensure the supercritical shafts crossing the critical speed safely. Due to design tolerances, manufacturing errors and time‐varying factors, the parameters of the damper are inherently uncertain ...

Robust Control for Uncertain Vertical Electric Stabilization System With Flexible Nonlinearity Using Backstepping Idea

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT A robust control method for the uncertain vertical electric stabilization system (VESS) with flexible nonlinearity is proposed, and the mismatched uncertainty is considered and compensated based on the backstepping idea. First, based on evaluating the coupling effects of the flexible nonlinearity, the analytical dynamics model of the VESS is ...

Navigating the Waves: The Global Pandemic's Impact on Container Shipping and Freight Rates Across Different Policy Scenarios

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT The COVID‐19 pandemic has reverberated across global industries, including the international container shipping industry, where freight rates have become highly volatile. However, shipping lines appeared to thrive, particularly during the pandemic's initial 2 years.

Phenology in winter‐deciduous relict Mediterranean forests as a tool to understand their adaptation to climatic seasonal cycles

open access: yesNordic Journal of Botany, EarlyView.
Winter deciduous forests signify a relict ecosystem that survives restricted to microclimatic zones of high mountains in the western Mediterranean Basin and they are well represented in the southern Iberian Peninsula (Sierra Nevada, Spain). Given the scarce knowledge of their phenological behaviour, the aim of this work was to obtain the annual ...

Nutritional priorities to support GLP‐1 therapy for obesity: A joint Advisory from the American College of Lifestyle Medicine, the American Society for Nutrition, the Obesity Medicine Association, and The Obesity Society

open access: yesObesity, EarlyView.
Abstract Background Glucagon‐like peptide 1 receptor agonists and combination medications (hereafter collectively referred to as GLP‐1s) are shifting the treatment landscape for obesity. However, real‐world challenges and limited clinician and public knowledge on nutritional and lifestyle interventions can limit GLP‐1 efficacy, equitable results, and ...
