Theoretical development of a dynamic stiffness matrix (DSM) based direct damping matrix identification method is revisited in this paper. This method was proposed to identify both the mechanism and ...

Matrix algebra and the Rayleigh-Ritz technique are applied to the development of the finite element method. The minimum potential energy theorem, calculus of variations, Galerkin's and the ...

Now, researchers at the University of Tsukuba have identified the roles of matrix stiffness and mechanotransduction in cardiac reprogramming, showing that matrices with softness comparable to ...

Bioengineers have demonstrated that the stiffness of the extracellular matrix used to culture stem cells really does matter. The research team also found that a protein binding the stem cell to ...

A pioneering study has revealed that increased stiffness in the extracellular matrix (ECM) of spinal discs impairs energy production in nucleus pulposus cells (NPCs), a key factor in ...
