Emory Guy Simmons 1920-2013.
Early life.—Emory was born 12 April 1920, in Hillsboro, Fountain County, Indiana, the son of Floyd and Estel May McAlister Simmons, the middle child of three girls and two boys. He was very fond of Minnie, his maternal grandmother, called ‘‘Dolly’’ by everyone, who lived with the family. The family moved to Crawfordsville, Indiana, before Emory entered school to a home whose former location is ...
متن کاملLucky Guy Knife Assault
We reported a young male with knife assault to his chest. He was transferred to the hospital without manipulating the knife. He was completely conscious and had sinus tachycardia and regular breathing. Emergency thoracotomy was performed and the knife was removed. No organ was damaged. This case presentation showed that in this kind of trauma, it is mandatory not to manipulate the penetrating f...
متن کاملThe Lasserre Hierarchy in Almost Diagonal Form
The Lasserre hierarchy is a systematic procedure for constructing a sequence of increasingly tight relaxations that capture the convex formulations used in the best available approximation algorithms for a wide variety of optimization problems. Despite the increasing interest, there are very few techniques for analyzing Lasserre integrality gaps. Satisfying the positive semi-definite requiremen...
متن کاملApproximate Lasserre Integrality Gap for Unique Games
In this paper, we investigate whether a constant round Lasserre Semi-definite Programming (SDP) relaxation might give a good approximation to the UNIQUE GAMES problem. We show that the answer is negative if the relaxation is insensitive to a sufficiently small perturbation of the constraints. Specifically, we construct an instance of UNIQUE GAMES with k labels along with an approximate vector s...
متن کاملGraph Isomorphism and the Lasserre Hierarchy
In this paper we show lower bounds for a certain large class of algorithms solving the Graph Isomorphism problem, even on expander graph instances. Spielman [25] shows an algorithm for isomorphism of strongly regular expander graphs that runs in time exp{Õ(n 13 )} (this bound was recently improved to exp{Õ(n 15 )} [5]). It has since been an open question to remove the requirement that the graph...
