Background. Recent studies have noted an increasing prevalence of obesity in HIV+ individuals. HIV+ individuals may be concerned about being “underweight” due to HIV/AIDS related stigma. We hypothesized that HIV+ individuals would exhibit a high degree of weight misperception, defined as discordance between perceived and actual body mass index (BMI). The objectives of our study were to determin...

A practical common weight scaling function methodology with an improved discriminating power for technology selection is introduced. The proposed scaling function methodology enables the evaluation of the relative efficiency of decision-making units (DMUs) with respect to multiple outputs and a single exact input with common weights. Its robustness and discriminating power are illustrated via a...

ABSTRACT: A difference labeling of a graph G is realized by assigning distinct integer values to its vertices and then associating with each edge the absolute difference of those values assigned to its end vertices. A decomposition of labeled graph into parts, each part containing the edge having a commonweight is called a common – weight decomposition. In this paper we investigate the existenc...

The use of weights is an increasingly popular conditioning technique, competitive sport and recreational activity among children, adolescents and young adults. Weight-training can cause significant musculoskeletal injuries such as fractures, dislocations, spondylolysis, spondylolisthesis, intervertebral disk herniation, and meniscal injuries of the knee. Although injuries can occur during the u...
