Introduction: The National Research Council Decadal Study on Terrestrial Analogs to Mars recommended the Bishop Tuff, exposed in the Volcanic Tableland, Bishop, California (Fig. 1), as an analog [1] because some Martian volcanoes and the Stealth region of southwestern Tharsis are thought to be composed of pyroclastic deposits [2–4]. Recent data from the Spirit rover also suggest that the Columb...

This talk will discuss some recent results on the complexity theory of quantum computing. The long term goal is to understand exactly the relationship between the new quantum complexity classes and the classic ones. It is assumed that you are not an expert in: quantum flavordynamics, quantum geometrodynamics, quantum hydrodynamics, quantum magnetodynamics, quantum triviality, Schrödinger’s equa...

See related article, pages 2533–2537 I n this exciting era of stroke prevention and treatment, the stroke neurologist is privileged and obliged to determine with reasonable certainty the cause of every cerebral or ocular vascular event. Investigation must seek evidence for either cardiac, large-artery, penetrating artery (lacunar) or, in their absence, for a growing miscellany of " other " caus...

In this paper, we present a novel approach, stealth multicast, which offers a practical solution for the adoption of network-level IP multicast. Rather than focusing on a global scale such as with previous approaches, stealth multicast optimizes efficiency on a domain-wise scale. In short, stealth multicast dynamically combines redundant data payloads into virtual groups for multicast transmiss...

Stealth navigation is a fundamental capability for a scout vehicle to e ectively perform reconnaissance missions. One component of stealth is the ability to plan paths that minimize visibility of the vehicle from target locations. This paper demonstrates a stealth planning system using visibility analysis on digital terrain elevation maps for path planning. Goal locations can be user speci ed o...
