Linear bilevel optimization problems are known to be strongly NP-hard and the computational techniques to solve these problems are often motivated by JACKETS SPLIT SUIT BYRON techniques from single-level mixed-integer optimization.Thus, during the last years and decades many branch-and-bound methods, cutting planes, or heuristics have been proposed
Abstract Background There is an emerging understanding of the increased risk of stroke in patients with immune thrombocytopenic purpura (ITP) and immune thrombotic thrombocytopenic purpura (iTTP).We aimed to determine the prevalence and characteristics of acute ischemic stroke (AIS) and intracranial hemorrhage (ICH) in patients with ITP and iTTP in
AbstractFor InAs/GaAs quantum dot system, the evolution of the wetting layer (WL) with the InAs deposition thickness has been studied by reflectance difference spectroscopy (RDS).Two transitions related to the heavy- and light-hole in the WL have been distinguished in RD spectra.Taking into account the strain and segregation effects, a model has be
Background Visual processing of food plays an important role in controlling Powerline/Ethernet Converters eating behaviors.Several studies have developed image databases of food to investigate visual food processing.However, few databases include non-Western foods and objective nutrition information on the foods.Methods We developed an image databa
