UNLABELLED Identifying portable methods to measure body composition may be more advantageous than using body mass index (BMI) to categorize associated health consequences. PURPOSE To compare the validity and reliability of a portable A-mode ultrasound (US) to a criterion three compartment model (3C) for the measurement of body composition. METHODS Forty-seven overweight and obese subjects p...

BACKGROUND In contrast to the well-characterized body growth and development of females with adolescent idiopathic scoliosis (AIS), the pubertal growth pattern of male patients has not been well-documented. Recently, significantly lower body weight (BW) and body mass index (BMI) were reported in males with AIS, and were thought to be related to curve progression. A case-control study was carrie...

In an earlier work [6] we presented a simple FM-index variant, based on the idea of Huffman-compressing the text and then applying the Burrows-Wheeler transform over it. The main drawback of using Huffman was its lack of synchronizing properties, forcing us to supply another bit stream indicating the Huffman codeword boundaries. In this way, the resulting index needed O(n(H0+1)) bits of space b...

Recent studies on the bat's auditory system indicate that the corticofugal system mediates a highly focused positive feedback to physiologically "matched" subcortical neurons, and widespread lateral inhibition to physiologically "unmatched" subcortical neurons, to adjust and improve information processing. These findings have solved the controversy in physiological data, accumulated since 1962,...

BACKGROUND Aging is associated with increases in fat mass (FM) and decreases in fat-free mass (FFM) that may affect physical capacity. However, it is not clear whether high FM or low FFM contribute more to a reduction in physical capacity. METHODS A structural equation modeling strategy was used to test an explanatory model of the association between body composition and physical capacity. Th...

The effect of spin relaxation on tunnel magnetoresistance (TMR) in a ferromagnet/superconductor/ferromagnet (FM/SC/FM) double tunnel junction is theoretically studied. The spin accumulation in SC is determined by balancing of the spin-injection rate and the spin-relaxation rate. In the superconducting state, the spinrelaxation time τs becomes longer with decreasing temperature, resulting in a r...
