Assessment of the Impact of the Rigidity of Nodes on the Operating Reliability of EPSs [PDF]

open access: yesE3S Web of Conferences, 2019
The operating reliability of electrical power systems is mostly based on the topology and parameters of the schemes considered in this article. The preliminary (before the calculation of operating conditions) analysis of the rigidity or sensitivity of ...

Rigidity of frameworks supported on surfaces [PDF]

open access: yes, 2012
A theorem of Laman gives a combinatorial characterisation of the graphs that admit a realisation as a minimally rigid generic bar-joint framework in $\bR^2$.

Data on the effects of ECM rigidity on actomyosin contractility and invadopodia activity in individual versus pairs of head and neck squamous cell carcinoma cells

open access: yesData in Brief, 2022
Migration through the extracellular matrix (ECM) is essential for cancer cells to escape the primary tumor and invade neighboring tissues with the potential for metastasis [1].

Matrix rigidity-modulated cardiovascular organoid formation from embryoid bodies.

open access: yesPLoS ONE, 2014
Stem cell clusters, such as embryoid bodies (EBs) derived from embryonic stem cells, are extensively studied for creation of multicellular clusters and complex functional tissues.

Actin crosslinking by α-actinin averts viscous dissipation of myosin force transmission in stress fibers

open access: yesiScience, 2023
Summary: Contractile force generated in actomyosin stress fibers (SFs) is transmitted along SFs to the extracellular matrix (ECM), which contributes to cell migration and sensing of ECM rigidity.

Standard Loading Profile in Matrix Rigidity Sensing [PDF]

open access: yesBiophysical Journal, 2018
It is important to learn features of locally applied forces by cells during matrix rigidity sensing, since the function of mechanosensing proteins would be affected by force magnitude, loading velocity, or even loading history. Here, we investigate a rigidity-sensing apparatus consisting of a contractile unit on matrices.

Rigidity percolation in dispersions with a structured viscoelastic matrix [PDF]

open access: yesPhysical Review E, 2005
This paper deals with rigidity percolation in composite materials consisting of a dispersion of mineral particles in a microstructured viscoelastic matrix. The viscoelastic matrix in this specific case is a hydrocarbon refinery residue. In a set of model random composites the mean interparticle surface-to-surface distance was controlled, changing ...

Extracellular Matrix Rigidity Promotes Invadopodia Activity [PDF]

open access: yesCurrent Biology, 2008
Invadopodia are actin-rich subcellular protrusions with associated proteases used by cancer cells to degrade extracellular matrix (ECM) [1]. Molecular components of invadopodia include branched actin-assembly proteins, membrane trafficking proteins, signaling proteins, and transmembrane proteinases [1]. Similar structures exist in nontransformed cells,

Extracellular matrix rigidity modulates neuroblastoma cell differentiation and N-myc expression

open access: yesMolecular Cancer, 2010
Neuroblastoma is a pediatric malignancy characterized by tremendous clinical heterogeneity, in which some tumors are extremely aggressive while others spontaneously differentiate into benign forms.
