Interval and fuzzy eigenfrequency analysis of uncertain substructured FE models
Computer Assisted Methods in Engineering and Science, 2022 This paper uses an interval and fuzzy finite element approach for the eigenfrequency analysis of a mechanical structure with uncertain parameters. The component mode synthesis method is applied for the numerical reduction of the structure, in order to ...

A distributed finite-element modeling and control approach for large flexible structures [PDF]
An unconventional framework is described for the design of decentralized controllers for large flexible structures. In contrast to conventional control system design practice which begins with a model of the open loop plant, the controlled plant is ...

Analysis of nonlinear structures via mode synthesis [PDF]
, 1975 An effective procedure for NASTRAN was developed that permits any number of substructures of any size to be synthesized for the purpose of developing normal modes of vibration of the complete structural system.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane
FEBS Letters, EarlyView.Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Polarization dependent Brillouin gain in randomly birefringent fibers
, 2009 An extensive study of the alignment between the pump, the signal and the polarization dependent gain (PDG) vectors in stimulated Brillouin amplification in randomly birefringent fibers is realized by numerically integrating the equations governing the ...

FEBS 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 ...

Application of System-level Analysis Method in Fan-driven Gearbox Test
Jixie chuandong, 2021 The fan-driven gearbox is characterized by complex structure and difficult system dynamics analysis. The accuracy of the component level model is verified through the modal analysis and the percussion modal test of the gearbox component.

Design Optimization Utilizing Dynamic Substructuring and Artificial Intelligence Techniques [PDF]
, 2008 In mechanical and structural systems, resonance may cause large strains and stresses which can lead to the failure of the system. Since it is often not possible to change the frequency content of the external load excitation, the phenomenon can only be ...
