PURPOSE The aim of this study was to determine children's walking speeds in elementary school hallways. A second aim was to determine the slowest but "good enough" walking speed if a teacher had to slow down her class's line to accommodate a student with a mobility limitation. METHODS The walking speeds of 370 children serving as class-line leaders were determined after measuring using a stop...

OBJECTIVE To determine the effectiveness of mobility device interventions in terms of activity and participation for people with mobility limitations. DESIGN Systematic review. Search of 7 databases during the period 1996 to 2008. METHODS Controlled studies and non-controlled follow-up studies were included if they covered both baseline and follow-up data and focused on activity and partici...

Persons with multiple sclerosis (PwMS) frequently experience limitations of ambulation in the course of their disease. Not surprisingly, in recent surveys PwMS considered lower extremity function as one of the most important bodily functions, and ranked mobility limitations as the most important factor affecting their quality of life. The impact of MS on ambulation is reflected in the fact that...

Singapore's life expectancy at birth and at age 65 continues to improve. Although this is a positive development, it is necessary to understand how much of this increased life expectancy is spent with and without mobility limitations. This research uses the latest round of the National Survey of Senior Citizens to examine the situation in 2011 and the possible changes that may have occurred sin...

The electronic conductance at zero temperature through a quantum wire with side-connected asymmetric quantum ring (as a scatter system) is theoretically studied using the non-interacting Hamiltonian Anderson tunneling method. In this paper we concentrate on the configuration of the quantum dot rings. We show that the asymmetric structure of QD-scatter system strongly influences the amplitude an...

These notes are a record of proceedings in the QMW Combinat-orics Study Group in November and December 1998. Since we are discrete mathematicians and know little quantum theory, the notes are not strong on the physics background (but we give references to several sources for this). We have tried to compare quantum with classical error correction where possible, and to provide enough information...

there are many claims that quantum mechanics plays a key role in the origin and/or operation of biological organisms. the mechanism of the meiosis, mitosis and gametes life cycle from the view-point of quantum for human has been represented. the quantum gates have been used to simulate these processes for the first time. the reason of several hundred sperms has been explained in the male too

Standard X-ray crystallography methods use free-atom models to calculate mean unit-cell charge densities. Real molecules, however, have shared charge that is not captured accurately using free-atom models. To address this limitation, a charge density model of crystalline urea was calculated using high-level quantum theory and was refined against publicly available ultra-high-resolution experime...

Standard quantum mechanics unquestionably violates the separability principle that classical physics (be it point-like analytic, statistical, or field-theoretic) accustomed us to consider as valid. In this paper, quantum nonseparability is viewed as a consequence of the Hilbert-space quantum mechanical formalism, avoiding thus any direct recourse to the ramifications of Kochen-Specker’s argumen...
