CONTEXT Various studies report decreased muscle activation in the concavity of the curve in patients with scoliosis. Such decreased muscle-performance capacity could lead to sustained postural deficits. OBJECTIVE To investigate whether specific asymmetrical sports therapy exercises rather than symmetrical back strengthening can increase EMG amplitudes of paraspinal muscles in the concavity of...

In these notes we follow the two papers [6, 7] where Marcus, Spielman and Srivastava developed a method that they coined the method of interlacing families. In [6] they proved the existence of infinite families of bipartite Ramanujan graphs for all degrees, and in [7] they provided a positive answer to the notorious Kadison– Singer problem. We take the opportunity to have a slightly more genera...

Automated nuclear segmentation is essential in the analysis of most microscopy images. This paper presents a novel concavitybased method for the separation of clusters of nuclei in binary images. A heuristic rule, based on object size, is used to infer the existence of merged regions. Concavity extrema detected along the merged-cluster boundary are used to guide the separation of overlapping re...
