Following an inguinal hernia repair with open or laparoscopic technique, 1–15% of patients show persistent neuralgia, a severe, potentially debilitating, complication. Several therapeutic procedures have been proposed, but consensus regarding choice of treatment has not yet been achieved. We performed a prospective study on 32 such cases. Patients underwent anaesthetic infiltration to identify, when...
This paper develops a new hierarchic definition of the notion concavity and provides an algorithm to determine the different level of concavities. To find the shape of first level concavities an active concavity model is developed. The model is based on the geometric heat differential equation, which evolves a curve in the direction of the difference between normal and tangent force, and normal force...
We give necessary and sufficient conditions for convergence of the self-normalized productg(n)X 1 X 2 ...X n X i12 X i22 ...X in-12 ,where X 1 ,X 2 ,...,X n are independent random variables, g(n) is an arbitrary function with g(n)->+~, as n->+~, and is summation over all integers...
