Dynamic Analysis of Electrically Assisted Turbocharger Rotor Considering Contact Effects in Nut Structures

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The rotor system of an electrically assisted turbocharger (EAT) is composed of multiple shaft components; The nonlinear connection and contact effects make it difficult to determine the system dynamic characteristics. To improve the modeling accuracy of EAT rotor system and evaluate the influence of contact between multi‐axis components and ...

Analysis of Mechanical‐Electrical‐Hydraulic Coupled Vibration Response Characteristics of Thermal Control Circulating Pumps Supported by Water‐Lubricated Bearings

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The operational reliability of thermal control circulation pumps is significantly restricted by the multi‐physics coupled environment. To reveal the vibration transmission mechanisms and dynamic response characteristics under multi‐field coupled excitations, a multi‐DOF coupled dynamic representation of the overall system, incorporating the ...

A tipping point for tipping points

open access: yesOikos, EarlyView.
Tipping points (TPs) – often understood as abrupt changes to a system – have become a popular framework for ecology and environmental science across spatial and temporal scales. The underlying, quantitative foundation of TP theory is built on mathematical models from catastrophe and predator–prey theories.

Exploring the causes and impact of pediatric complicated mild traumatic brain injuries

open access: yesPM&R, EarlyView.
Abstract Background Traumatic brain injury (TBI) is a leading cause of morbidity and mortality in children, with mild TBI (mTBI) accounting for approximately 80% of cases. Complicated mTBI (c‐mTBI) is characterized by radiographic evidence of intracranial abnormalities and/or skull fractures.

Understanding the changes in endogenous GA3 in relation to developmental transitions in cauliflower (Brassica oleracea var. botrytis L.).

open access: yesPLoS ONE
Cauliflower is a crop with intricate developmental transitions influenced by both external and internal cues. Plant growth regulators (PGRs) play a key role in developmental transitions and plant responses to environmental factors.
