From the earliest studies with epithelial cells implanted into detrusor muscle to later experiments on smooth muscle in defined collagen gels, cell niche and extracellular matrix (ECM) have been ...

It is well-known that if we have an approximate eigenvalue λ̂ of a normal matrix A of order n, a good approximation to the corresponding eigenvector u can be computed by one inverse iteration provided ...

Let X, Y be two subspaces of summability domains of matrices with real or complex entries determined by speeds of the convergence, i.e.; by monotonically increasing positive sequences λ and μ. In this ...
