—Elevated summertime temperatures in urban 'heat islands' increase cooling-energy use and accelerate the formation of urban smog. Except in the city's core areas, summer heat islands are created mainly by the lack of vegetation and by the high solar radiation absorptance by urban surfaces. Analysis of temperature trends for the last 100 years in several(More)
1. To examine the activity of single units in the lateral striatum of the awake rat with respect to sensorimotor function, 788 units were recorded during locomotion and passive testing. The focus of this report is on 138 units (18%) that fired in relation to sensorimotor activity of a single limb. The remaining units were related to other body parts (16%),(More)

New models and capabilities in the Jet Propulsion Laboratory's (JPL) Lunar Surface Operations Simulator (LSOS) are reported in this paper. LSOS is a simulator built to support surface operations design and planning for future lunar missions. LSOS models surface systems, their mechanical properties, and operations. In addition to simulating the dynamic(More)

As part of the Space Exploration Analysis and Simulation (SEAS) task, the National Aeronautics and Space Administration (NASA) is using physics-based simulations at NASAs Jet Propulsion Laboratory (JPL) to explore potential surface and near-surface mission operations at Near Earth Objects (NEOs). The simulator is under development at JPL and can be used to(More)
The scanning tunneling microscope (STM) can be used to measure current-voltage characteristics on an atomic scale. The attachment of copper phthalocyanine molecules, in contrast to a variety of other molecules, to graphite changes the electrical characteristics of the STM from relatively symmetric to highly asymmetric or rectifying. Evidence is presented to(More)
