Assessment of the correlation between the numerical and experimental dynamic characteristics of the bucket wheel excavator in terms of the operational conditions [PDF]

open access: yesFME Transactions, 2013
In the paper authors present their attempt in the validation process of the numerical model on the basis of experimental results. The Modal Assurance Criterion between the numerical and experimental model was selected as the indicating factor.

New approach based on operational strain modal analysis to identify dynamical properties of the high-speed reciprocating operation mechanism

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2019
A high-speed reciprocating operating mechanism with fast running and frequent stopping produces a certain vibration due to inertia. The inherent vibration of this mechanism becomes a key factor affecting positioning accuracy and time.

Effect of DFPP on Ferroptosis in Peripheral Blood CD14+ Monocytes of Hyperlipidemic Patients Involving the ACSL4/LPCAT3/ALOX5 Pathway

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Hyperlipidemia is a major risk factor for atherosclerotic cardiovascular disease (ASCVD). Although statins are the cornerstone of lipid‐lowering therapy, their use may be limited in some patients by adverse effects. This study evaluated the possible impact of non‐drug treatment using double‐filtration plasmapheresis (DFPP) on CD14+

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Operational Modal Analysis of Damage Gear

open access: yesInternational Journal of Innovative Technology and Exploring Engineering, 2020
As natural frequencies and mode shapes are often a key to understanding dynamic characteristics of structural elements, modal analysis provides a viable means to determine these properties. This paper investigates the dynamic characteristics of a healthy and unhealthy condition of a commercially used helical gear using the Frequency Domain ...
