Amazonian The youngest of the geologic epochs on Mars identified through geoiogic mapping of superposition relations, and the area! density of impact craters. caldera An irregular collapse feature formed over the evacuated magma chamber within a volcano. central volcano Emplacement of volcanic materials from a centralized source vent rather than along a distributed line of vents, composite volc...

Abstract Movement of soil and rock masses down the slope or known as landslide is a natural activity that can pose danger to humans. Generally, be influenced by slope, materials (rock/soil), rainfall. Morphologically, study area, which located in borders Tembalang Banyumanik Districts, Semarang City, hill quite steep. It has potential experience landslides. Landslide occurences at area do not a...

Water probably flowed across ancient Mars, but whether it ever exists as a liquid on the surface today remains debatable. Recurring slope lineae (RSL) are narrow (0.5 to 5 meters), relatively dark markings on steep (25° to 40°) slopes; repeat images from the Mars Reconnaissance Orbiter High Resolution Imaging Science Experiment show them to appear and incrementally grow during warm seasons and ...

When users search for the routes between two places using map based services, these services compute and provide the top candidate routes based on shortest geometric distances or ideal time consuming. However, other real factors like physical exertion and practical time consuming will influence user experience, and the environmental factors like steep slope and traffic jam that result in these ...

Human ventricular tissue as well as several animal ventricular preparations show a biphasic shape of the action potential duration restitution curve, with a local maximum at low diastolic intervals. We study numerically how the location and properties of this nonmonotonicity affect the stability of spiral waves. We find that, depending on the slopes of the ascending and of the descending parts ...

Calculations are presented of the rate of energy conversion of the barotropic tide into internal gravity waves above topography on the ocean floor. The ocean is treated as infinitely deep, and the topography consists of periodic obstructions; a Green function method is used to construct the scattered wavefield. The calculations extend the previous results of Balmforth et al. for subcritical top...

This paper presents an approach for slip prediction from a distance for wheeled ground robots using visual information as input. Large amounts of slippage which can occur on certain surfaces, such as sandy slopes, will negatively affect rover mobility. Therefore, obtaining information about slip before entering such terrain can be very useful for better planning and avoiding these areas. To add...

[1] The Mars Orbiter Camera on board the Mars Global Surveyor spacecraft has returned images of numerous dark streaks that are the result of down-slope mass movement occurring under present-day martian climatic conditions. We systematically analyze over 23,000 high-resolution images and demonstrate that slope streaks form exclusively in regions of low thermal inertia (confirming earlier results...

O nce you get to Swanton Pacific Ranch in the coastal mountains north of Santa Cruz, it's pretty obvious the 3,200-acre spread offers many things you just won't find at Cal Poly: trees, for one thing. A whole forest full of them 2,100 acres to be exact. They cover steep mountain slopes and march in tall columns down to grassy meadows. A river runs through it: Scott Creek and its tributaries. "T...

To the Editor:—The critique by Eger et al. on the article by Eckenhoff and Johansson concerns combining the dose–response curves of several ion channels to make them steeper. The slopes of the in vivo studies are steep, whereas those of the in vitro studies are gradual. Both groups anticipate that when several binding sites among ion channels are combined, the dose–response curves may become st...
