       Abstract: This work introduces a wireless, solid-state, portable, and automated device capable of semi-continuously measuring the total ammonia (ammonia (NH3) and ammonium (NH4 + )) levels of fluids, including biological samples. This device reliably measures the total ammonia of biological samples... Read more

Cardiac electrogram (EGM) signals and electrophysiologic (EP) characteristics derived from them such as amplitude and timing are central to the diagnosis and therapeutic management of arrhythmias. Bipolar EGMs are often used but possess polarity and shape dependence on catheter orientation... Read more

Current frameworks for evaluating diagnostic tests are constrained by a focus on diagnostic accuracy, and assume that all aspects of the testing process and test attributes are discrete and equally important. Determining the balance between the benefits and harms associated... Read more
