It is common practice to study jump landing mechanics by having subjects step off a box set at a certain height instead of landing from a jump. This practice assumes that the landing mechanics are similar between stepping off a box and a countermovement jump as long as the heights can be matched. The mechanics of the two methods had never been compared when landing from identical heights. Thus,...
BACKGROUND Body fat percentage (BF%) determined by bioelectrical impedance analysis is widely used at home and in medical check-ups. However, the clinical significance of measuring BF% has not been studied in detail. METHODS AND RESULTS A cross-sectional study was carried out on a cohort of 10,774 middle-aged Japanese men who had undergone an annual check-up in 2008. Cut-off points were eva...
The development of strategies for addressing arrays of nanoscale devices is central to the implementation of integrated nanosystems such as biological sensor arrays and nanocomputers. We report a general approach for addressing based on molecular-level modification of crossed semiconductor nanowire field-effect transistor (cNW-FET) arrays, where selective chemical modification of cross points i...
Objective: The effects of scoliotic deformity on the biomechanics of gait are not clear. The aim of this study was to compare the spatiotemporal variables during gait in adolescent idiopathic scoliosis and healthy individuals. Methods: Eighteen healthy adolescent girls and 19 adolescent patients with idiopathic scoliosis that were matched for age, height, mass and BMI participated in this stud...
Abstract This work introduces a new one-step method with three intermediate points for solving stiff differential systems. These types of problems appear in different disciplines and, particular, derived from chemical reactions. In fact, the term “stiff”’ was coined by Curtiss and Hirschfelder an article on kinetics (Hirschfelder, Proc Natl Acad Sci USA 38:235–243, 1952). The techniques interpo...
