OBJECTIVE To determine cut offs to define thinness in children and adolescents, based on body mass index at age 18 years. DESIGN International survey of six large nationally representative cross sectional studies on growth. SETTING Brazil, Great Britain, Hong Kong, the Netherlands, Singapore, and the United States. SUBJECTS 97 876 males and 94 851 females from birth to 25 years. MAIN OU...

The aim of this study was to investigate the need for different cut-off points, according to animal age and the purpose of testing, for two of the most widely used serological techniques in bovine neosporosis, IFAT and a crude antigen ELISA (Civtest, HIPRA). Therefore, the population reference sera used were defined using a combination of multiple criteria such as epidemiological/clinical and h...

We consider the positive semidefinite (psd) matrices with binary entries. We give a characterisation of such matrices, along with a graphical representation. We then move on to consider the associated integer polytopes. Several important and well-known integer polytopes — the cut, boolean quadric, multicut and clique partitioning polytopes — are shown to arise as projections of binary psd polyt...

OBJECTIVE Explosive ordnance disposal (EOD) often requires technicians to wear multiple protective garments in challenging environmental conditions. The accumulative effect of increased metabolic cost coupled with decreased heat dissipation associated with these garments predisposes technicians to high levels of physiological strain. It has been proposed that a perceptual strain index (PeSI) us...

We report, for the first time, a silicon carbide (SiC) based metal semiconductor field effect transistor (MESFET) which has a recessed p-buffer layer into the channel region near the source and a recessed channel into the p-buffer layer region near the drain under the gate. The length and thickness of the channel recess into the p-buffer layer are larger than the pbuffer recess into the channel...

BACKGROUND We aimed to determine whether synovial fluid (SF) biomarkers can predict the progression of articular cartilage damage as determined by arthroscopic evaluation during and after anterior cruciate ligament (ACL) reconstruction. METHODS Arthroscopic assessment of articular cartilage damage was performed twice in 62 patients, first during ACL reconstruction and then approximately 2 yea...
