Exploring the Use of Parametric Excitation

open access: yes, 2010
In the past parametric excitation was considered almost exclusively to have only negative effects on the dynamics of systems. Therefore, the focus of research studies was mostly on how to avoid or at least minimize the adverse consequences of parametric ...

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

open access: yesFEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Dynamic loads and interference between meshing pairs in multi-stage geared system

open access: yesNihon Kikai Gakkai ronbunshu
Inside realistic multi-stage geared system the dynamic meshing tooth loads are in interference mutually between meshing pairs. This report deals with this multi-stage crosstalk theoretically by Receptance Operator Procedure (ROP) that has been developed ...

MagmaFlow: A desktop platform for artificial intelligence‐driven expression analysis

open access: yesFEBS Open Bio, EarlyView.
MagmaFlow is a free, no‐code platform for gene expression analysis. It generates interactive volcano plots, links genes to literature, pathways, and diseases, prioritizes candidates using millions of publications, identifies affected biological processes, builds network diagrams, and exports publication‐ready figures and reports for macOS and Windows ...

Nonlinear vibration of sheet metal plates under interacting parametric and external excitation during manufacturing

open access: yes, 2005
This study is motivated by the vibrations that plague coating processes used in the manufacturing of coated sheet metal. These vibrations arise from time-dependent tension fluctuations within the sheet metal plate as well as from the eccentricity of the ...

Parametric Excitation of Hangers at the Hardanger Bridge [PDF]

open access: yes, 2016
There has been observed large vibrations on some of the longest hangers at the Hardanger Bridge. Parametric excitation has been suggested as the cause of these vibrations. The main aim of this thesis has therefore been to verify if this is the case. As a

KDAC6 alters cell morphology and motility through positive and negative modulation of F‐actin distribution

open access: yesFEBS Open Bio, EarlyView.
KDAC6 has been associated with cell motility and actin structures, but specific domain contributions are not established. The two catalytic domains have differential effects on motility and F‐actin regulation, affecting cortical F‐actin density, motility, stress fibers, and cell spreading.

Self-Excited vibration quenching by means of parametric excitation: the effect of an additional external excitation

open access: yes, 2003
The survey of the state-of-art mentiones when the parametric combination resonance for the self-excited vibration can be partly or even suppressed. This phenomenon is a parametric anti-resonance.
