We have developed a biologically based underwater, autonomous vehicle modeled after a simple vertebrate, the sea lamprey. The robot consists of a cylindrical Plexiglas electronics bay with a polyurethane undulator actuated by shape memory alloy artificial muscles. Sensors include a compass, pitch and roll inclinometers and sonar rangers, the signals of which are quantized into a labeled line co...

BACKGROUND Fatigue is a biological phenomenon that involves a feeling of extreme physical or mental tiredness that could potentially cause some severe chronic diseases. Recently, diet therapy has provided a new alternative to alleviate physical fatigue. In our previous study, addition of Cordyceps militaris (C. militaris) into an extruded product was shown to provide high nutrition and unique f...

CONTEXT The prevalence of shoulder pain among competitive swimmers is high, but no guidelines exist to reduce shoulder injuries. Elucidating differences between swimmers with and without shoulder pain can serve as a basis for the development of a program to prevent shoulder injury that might lead to pain and dysfunction. OBJECTIVE To determine whether physical characteristics, exposure, or tr...

Aerial–aquatic robots have promising applications due to their ability operate in air and water with different motion modes. However, challenges such as water/air transition multimedia movement still limit development. Inspired by the aerial–aquatic behavior of wild ducks, an robot tunable tilting motors a delta wing is introduced. The can perform multimode motion, including flying air, swimmin...

  Background: To determine the effects of probiotic yogurt on performance and health status of young adult female endurance swimmers.   Methods: In a randomized controlled trial, 46 endurance swimmers girls with mean age of 13.8 ±1.8 years, weight of 48.6±7.5kg and height of 159±5.6cm, were studied. Subjects were randomly assigned into two groups, receiving either 400 ml probiotic yogurt (inter...
