We consider asymptotics of orthogonal polynomials with respect to a weight e ?Q(x) dx on R, where either Q(x) is a polynomial of even order with positive leading coeecient, or Q(x) = NV (x), where V (x) is real analytic on R and grows suuciently rapidly as jxj ! 1. We formulate the orthogonal polynomial problem as a Riemann-Hilbert problem following the work of Fokas, Its and Kitaev. We employ ...

We initiate the study of finding the Jaccard center of a given collection N of sets. For two sets X,Y , the Jaccard index is defined as |X ∩ Y |/|X ∪ Y | and the corresponding distance is 1− |X ∩Y |/|X ∪Y |. The Jaccard center is a set C minimizing the maximum distance to any set of N . We show that the problem is NP-hard to solve exactly, and that it admits a PTAS while no FPTAS can exist unle...

Abstract Introduction Trocar site hernia (TSH) is a complication of minimally invasive surgery that often underestimated. These lesions cause patient discomfort and require for their correction. Although there are some case reports laparoscopic repair TSH, data missing in the literature about this specific topic. The aim study to evaluate safety efficacy TSH. Methods We collected regarding 213 ...
