Production, transformation, and degradation are the principal components of the cycling of dissolved organic matter (DOM) in marine systems. Heterotrophic Bacteria (and Archaea) play a large part in this cycling via enzymatic decomposition and intracellular transformations of organic material to inorganic carbon (C), nitrogen (N), and phosphorus (P).

Smooth and convenient user control of prostheses is critical to restore motor and cognitive functions in amputees. This study aims to develop a smart system supporting volitional control of prostheses directly from user' thought without any interface manipulation. An ultra-portable, wireless-enabled, and low powered device prototype was developed to amplify(More)
Human gait is a complex process resulting from contraction of various muscle groups with different sizes. With the loss of a lower limb, amputees use passive prosthetics to replace the lost limb and regain function. Operating a prosthetic leg, requires more metabolic energy expenditure and greater pressure on the residual limb. In order to understand the(More)
