Background: Collagen, the most abundant protein in the human body, and as an extracellular matrix protein, has an important role in the fiber formation. This feature of the collagen renders  establishment of the structural skeleton in tissues. Regarding specific features associated with the collagen, such as, formation of the porous structure, permeability and hydrophilicity, it can also be use...

Structural analysis is concerned with the decomposition of traffic matrix into basis vectors, which corresponds to temporal patterns. In general, the effectiveness of basis vectors is determined by the extent to which it approximates the current week as well as subsequent consecutive week traffic matrix, i.e., the basis vectors should be temporally stable. Principal component analysis (PCA) is ...

Atrial fibrillation (AF) is a common arrhythmia, affecting approximately 5% of the population older than 65 years; the arrhythmia is associated with significant morbidity and mortality, and it is challenging and often frustrating to treat (1,2). There is a tendency for AF to become chronic and more resistant to cardioversion with increasing duration of the arrhythmia (3). Although the details a...

We consider the matrix completion problem of recovering a structured matrix from noisy and partial measurements. Recent works have proposed tractable estimators with strong statistical guarantees for the case where the underlying matrix is low–rank, and the measurements consist of a subset, either of the exact individual entries, or of the entries perturbed by additive Gaussian noise, which is ...

In this paper, we present a new image indexing and retrieval method for image database applications. We introduce a novel image content description feature termed Scene Structural Matrix (SSM). The SSM captures the overall structural information of the scene by indexing the geometric features of the image. In this work, we also introduce a constraint adaptive image segmentation method termed Mi...
