A stair Laguerre pseudospectral method is proposed for numerical solutions of differential equations on the half line. Some approximation results are established. A stair Laguerre pseudospcetral scheme is constructed for a model problem. The convergence is proved. The numerical results show that this new method provides much more accurate numerical results than the standard Laguerre spectral me...

OBJECTIVE The aim of this study was to compare gaze behaviour during stair and ramp walking between patients with chronic peripheral vestibular hypofunction and healthy human subjects. METHODS Twenty four (24) patients with chronic peripheral vestibular hypofunction (14 unilateral and 10 bilateral) and 24 healthy subjects performed stair and ramp up and down walks at self-selected speed. The ...

Composite adaptive grid (CAG) methods for solving hyperbolic partial differential equations (PDE's) are discussed in this paper. Composite grids are used at the coarsest level to deal with domains with complicated geometries. Stair step grids developed for composite grids are also used in the ner levels to cover reened regions. New data structures for stair step grids are proposed and implement...

objective : priapism is defined by persistent, painful penile erection which occurs without sexual stimulation. methadone is used as an analgesic and is also used in detoxification and maintenance protocol for opioid dependence treatment. here we will report a case of a male with priapism after rapid discontinuation doses of methadone. case presentation : the case was a young married male who r...

During coronary angioplasty, a stair-step decrease in peak S-T segment elevation from the first to the second coronary occlusion has been assumed to indicate a preconditioning (PC) effect. This association was evaluated with myocardial electrograms in rabbits, which revealed that two sequential 5-min coronary occlusions resulted in a marked decrease in the area under the S-T segment voltage-tim...

Stair-climbing is an important skill for promoting independence and activities of daily life and is a key component of rehabilitation therapies for physically disabled children. This thesis describes the design and evaluation of an interactive musical stairs system for children engaged in stairclimbing physical therapies. The achievement of a targeted therapeutic goal, namely, use of reciprocal...

Explosive-type strength training may alter kinetics and neuromuscular activity during stair ascent in elderly women. This may improve functional ability. Nineteen women (69.7 ± 3.4 yr) were randomly allocated to strength training (TG; twice per wk, 12 wk) or a control group (CG). Stair ascent was assessed at self-chosen (AFV), standardized (ASV), and maximal velocity (AMV) pre- and posttraining...

ISSUE ADDRESSED This study investigated the effectiveness of positive and negative-themed message prompts encouraging stair use at the point of choice between an elevator and stairwell in a professional workplace. METHODS A simple time series design using two control periods assessed the efficacy of positive and negative messages on the pedestrian choice between stairs and an elevator in a re...
