It is generally believed that structural changes in the extracellular matrix are necessary for cell migration, wound repair and tissue remodeling. Matrix metalloproteases are the major family of proteolytic enzymes responsible for degrading extracellular matrix components, and have been implicated in all of these biological processes. They form part of a superfamily of zinc peptidases known as ...

Articular cartilage-on-bone has been subjected to repeated impact loading in vitro and the associated structural changes occurring in the general matrix examined by optical and transmission electron microscopy (TEM). The study shows that repeated trauma transforms the pseudorandom arrangement of fibrils comprising the general matrix of normal articular cartilage into a structural configuration ...

Abstract Different methods to address the isomorphism in kinematic chains existed earlier and is well reported. In all methods, link-adjacency matrix (LAM) represents structural information of a given chain. Having gathered large collection co-spectral belonging number chain categories possessing (containing up 20 links 13 degrees freedom), present work aims at addressing by developing implemen...

in this research, the effect of different biopolymers such as polyethylene glycol (peg) and polyvinylalcohol (pva) on synthesis and characterization of polymer/cobalt ferrite (cf) nano-composites bymechanical alloying method has been systematically investigated. the structural, morphological andmagnetic properties changes during mechanical milling were investigated by x-ray diffraction (xrd),fo...

We propose a new retrieval system based on musical structure using symbolic structural queries. The aim is to compare musical form in audio files without extracting explicitly the underlying audio structure. From a given or arbitrary segmentation, an audio file is segmented. Irrespective of the audio feature choice, we then compute a selfsimilarity matrix whose coefficients correspond to the es...

This paper discusses the effective length factor of columns in Khorjini frames. In order to find this factor, a proper approximated method is proposed. In addition, accurate analysis is performed and the results are compared with those from the proposed technique. The comparison demonstrates the accuracy of presented FORMULATIONS. The proposed method is similar to Julian and Lawrence's, which i...
