Following the “decomposition-and-ensemble” principle, the empirical mode decomposition (EMD)-based modeling framework has been widely used as a promising alternative for nonlinear and nonstationary time series modeling and prediction. The end effect, which occurs during the sifting process of EMD and is apt to distort the decomposed sub-series and hurt the modeling process followed, however, ha...

OBJECTIVE Mortality and morbidity related to right ventricular failure remain a problem for the long-term outcome of congenital heart diseases. Therapeutic innovation requires establishing an animal model reproducing right ventricular dysfunction secondary to chronic pressure-volume overload. METHODS Right ventricular tract enlargement by transvalvular patch and pulmonary artery banding were ...

[1] Upper oceanic crust within the Cocos Plate offshore northwestern Costa Rica is dominated by sill intrusions of various ages, recognized regionally as smooth, high amplitude seismic reflections at the base of the sedimentary sequence and locally by dolerites and microgabbros recovered by drilling. Earlier interpretation of seafloor magnetic anomalies documented a set of spreading ridge jumps...

This paper presents an approach to process raw lidar 3-D point clouds over urban area and extract terrain, buildings and other urban features. In the initial step, “non-ground points” are separated from ground points using a one dimensional filtering process based on the slope between two consecutive points in the point cloud and the terrain elevation in the vicinity of the points. In the next ...

Sandstone intrusions are found in all sedimentary environments but have been reported most commonly from deep-water settings. They also appear to be more frequently developed in tectonically active settings where applied tectonic stresses facilitate development of high fluid pressures within the sediments. A variety of mechanisms have been cited as triggers for clastic intrusions. These include...

[1] Dilatational source deformations associated with two unusual M 3+ earthquakes in the area of the 2004–2008 Yellowstone, WY, accelerated uplift episode were identified through detailed analysis of moment tensor inversions. Pressurized hydrothermal fluids are suggested to be associated with the dilatational source processes of these unusual earthquakes, which is consistent with the mechanism ...

Synopsis: The Loch Leven basin (56° 12' N, 3° 23' W) in the Midland Valley of Scotland has been identified as the site of the primary impact of a low-angle oblique impact event dating from the end of the Carboniferous. Together with two further downrange structures, it forms a chain of craters which appear to have been produced by fragments of a large asteroid which disintegrated on impact. Top...
