Comparative analysis of rigidity across protein families [PDF]
, 2008 We present a comparative study in which 'pebble game' rigidity analysis is applied to multiple protein crystal structures, for each of six different protein families.

Rigidity of silicone substrates controls cell spreading and stem cell differentiation. [PDF]
, 2016 The dependences of spreading and differentiation of stem cells plated on hydrogel and silicone gel substrates on the rigidity and porosity of the substrates have recently been a subject of some controversy.

Rigidity of frameworks on expanding spheres [PDF]
, 2017 A rigidity theory is developed for bar-joint frameworks in $\mathbb{R}^{d+1}$ whose vertices are constrained to lie on concentric $d$-spheres with independently variable radii.

Complexity of linear circuits and geometry [PDF]
, 2015 We use algebraic geometry to study matrix rigidity, and more generally, the complexity of computing a matrix-vector product, continuing a study initiated by Kumar, et. al.

A Unified Dissertation on Bearing Rigidity Theory
, 2021 This work focuses on the bearing rigidity theory, namely the branch of knowledge investigating the structural properties necessary for multi-element systems to preserve the inter-units bearings when exposed to deformations. The original contributions are

Simple Riemannian surfaces are scattering rigid [PDF]
, 2014 Scattering rigidity of a Riemannian manifold allows one to tell the metric of a manifold with boundary by looking at the directions of geodesics at the boundary.

EVALUATION OF IRIDOCILIARY AND LENTICULAR ELASTICITY USING SHEAR-WAVE ELASTOGRAPHY IN RABBIT EYES
Acta Medica, 2014 Introduction: A previous study has employed shear-wave ultrasound elastographic imaging to assess corneal rigidity in an ex-vivo porcine eye model. This study employs the same modality in vivo in a rabbit eye model in order to assess lens, ciliary body ...

A rigidity result for normalized subfactors
Journal of Operator Theory, 2021 We show a rigidity result for subfactors that are normalized by a representation of a lattice Γ in a higher rank simple Lie group with trivial center into a finite factor. This implies that every subfactor of LΓ which is normalized by the natural copy of Γ is trivial or of finite index.

Rigidity results in generalized isothermal fluids [PDF]
Annales Henri Lebesgue, 2019 We investigate the long-time behavior of solutions to the isothermal Euler, Korteweg or quantum Navier–Stokes equations, as well as generalizations of these equations where the convex pressure law is asymptotically linear near vacuum. By writing the system with a suitable time-dependent scaling we prove that the densities of global solutions display ...

Using Elimination Theory to construct Rigid Matrices [PDF]
, 2013 The rigidity of a matrix A for target rank r is the minimum number of entries of A that must be changed to ensure that the rank of the altered matrix is at most r.
