Steep, short-crested waves, as well as a large variety of three-dimensional propagating wave patterns have been created in laboratory, utilizing a plunging half-cone. Monochromatic waves, over a range of frequencies and amplitudes through breaking and including soliton wave groups near resonance, have been observed and studied in a small wave flume. This monochromatic wavemaker creates complex ...

Encouraging an active lifestyle is an essential part of successful rehabilitation programs, and the link between physical activity and quality of life (QOL) is well established among patients with mobility disorders. Biomechanical aspects of wheelchair design play an important role in physical activity and social participation of disabled individuals. This review focuses on key biomechanical fe...

PURPOSE The optimal method of posterior cruciate ligament (PCL) reconstruction is not known. The purpose was to evaluate the biomechanical and clinical literature comparing open tibial inlay and arthroscopic transtibial PCL reconstructions and determine which method of reconstruction is superior. METHODS A systematic review of the literature was performed on PubMed. Biomechanical and clinical...

one of the most common diseases associated with musculo-skeletal ailment is low back pain which is epidemic among general public. if manual tasks are performed inappropriately by workers at workplaces, it may cause back pain in the lumbar spine. in recent years, a variety of assistive devices has been presented and used to utilize a passive force generator which has been effective in decreasing...

We describe a model for the compliance of a nanoimprint stamp with a grid of backside grooves, as proposed by Nielsen et al. [1]. We integrate the model with a fast simulation technique that we have previously demonstrated [2], to show how etched stamp-flexures reduce systematic, pattern-dependent residual layer thickness (RLT) variations while attenuating the contribution of random wafer nanot...

of amitriptyline is reported.The disease process was accompanied by noticeable loss of lung compliance, and a gross diffusion defect at alveolar level. It seems unlikely that the course was that of an aspiration or bronchopneumonia, and clinically and pathologically it resembled the changes seen in surfactant deficiency. It is suggested that amitriptyline in overdosage may interfere with the pr...

CONTEXT International differences in compliance of patients undergoing hemodialysis are poorly characterized and could contribute to international survival differences. OBJECTIVE To compare international differences in patient compliance with hemodialysis treatments. DESIGN A prospective observational study of patients undergoing hemodialysis in 1995 and a cross-sectional survey of health c...

Birdsong is a complex behavior, which results from the interaction between a nervous system and a biomechanical peripheral device. While much has been learned about how complex sounds are generated in the vocal organ, little has been learned about the signature on the vocalizations of the nonlinear effects introduced by the acoustic interactions between a sound source and the vocal tract. The v...

Modeling a complex phenomenon such as the mind presents tremendous computational complexity challenges. Modeling field theory (MFT) addresses these challenges in a non-traditional way. The main idea behind MFT is to match levels of uncertainty of the model (also, a problem or some theory) with levels of uncertainty of the evaluation criterion used to identify that model. When a model becomes mo...
