Action potentials (APs) generated and sustained by ionic currents flowing through neural cell's membrane constitute the main way these cells communicate with each other. The most common, although not the only possible mechanism of generating APs, involves sodium influx that ensures cell depolarization and potassium efflux that ensures cell repolaroization.(More)
The energy efficiency of an action potential (AP) is typically defined as the amount of capacitive current used to depolarize the membrane relative to the amount of ATP necessary to reset the displacement of sodium and potassium ions that occurs during the AP. Research in recent years suggests that at least some neurons have been optimized for(More)
Rover-mounted geotechnical systems are of paramount importance to lunar trafficability assessment, construction, and excavation/mining toward establishing permanent human presence on the Moon. These tools can also be used to determine density, when the regolith is used as radiation shield, for example. Two popular in-situ devices for establishing(More)
ACM's career consultant, Jack Wilson, answers questions from students about their forthcoming careers in computing and information technology. A: Effective cover letters have three parts: 1. An opening. Your intro should contain some kind of a "hook" or statement that will get the reader's attention and make them want to continue reading. Perhaps include a(More)
