A natural slope undergoing recurrent movements caused by rainfall-induced groundwater table rises is studied using a novel method. The strength and displacement parameters are back-calculated force-equilibrium-based finite method (FFDM) based on the first event of movement recorded in monitoring period. Slope displacements response to subsequent predicted FFDM material parameters. Important fac...

The discovery of three new species of Enyalioides from the tropical Andes in Ecuador and northern Peru is reported. Enyalioidesaltotambo sp. n. occurs in northwestern Ecuador and differs from other species of Enyalioides in having dorsal scales that are both smooth and homogeneous in size, a brown iris, and in lacking enlarged, circular and keeled scales on the flanks. Enyalioidesanisolepis sp....

OBJECTIVES To determine the feasibility of predicting static and dynamic peak back-compressive forces based on (1) static back compressive force values at the lift origin and destination and (2) lifting speed. METHODS Ten male subjects performed symmetric mid-sagittal floor-to-shoulder, floor-to-waist, and waist-to-shoulder lifts at three different speeds (slow, medium, and fast), and with tw...

To investigate the toppling displacement evolution characteristics of anti-dip rock slopes, Xiaodongcao-Zhengjiadagou bank slope is taken as an engineering case, and firstly, geological geometric distribution are obtained by superimposing lithology, slope, elevation raster layers through ArcGIS, partition with largest area Lower Triassic Daye Formation, bottom elevation, medium slope; based on ...

We describe two new species of frogs of the genus Pristimantis from the eastern slopes of the Ecuadorian Andes, at Parque Nacional Llanganates. The new species are characterized by the spiny appearance typical of several species inhabiting montane forests. Pristimantis yanezi sp. n. is most similar to Pristimantis colonensis and Pristimantis incanus but differs from both in groin coloration and...

This article reinvestigates the claim by P. Verhaeghen, J. Cerella, and C. Basak (2004) that the focus of attention in working memory can be expanded from 1 to 4 items through practice. Using a modified version of Verhaeghen et al.'s n-back paradigm, Experiments 1 and 3 show that a signature of a one-item focus, the time cost for switching between items in working memory, persists over practice...

This study validates the use of ambulatory EMG monitoring as a measure of exercise compliance. The model rehabilitative exercise used was the Prone Back Extension. Thirty-two undergraduate volunteers were videorecorded as they performed the exercise alone in a closed room. The correlation between a direct observation count of the number of repetitions and an independent EMG-based count was .95....

Generation of coherent short-wavelength radiation across a plasma column is dramatically improved under traveling-wave excitation (TWE). The latter is optimized when its propagation is close to the speed of light, which implies small-angle target-irradiation. Yet, short-wavelength lasing needs large irradiation angles in order to increase the optical penetration of the pump into the plasma core...

This paper presents a parallel algorithm for calculating the eight-directional (D8) up-slope contributing area in digital elevation models (DEMs). In contrast with previous algorithms, which have potentially unbounded inter-node communications, the algorithm presented here realizes strict bounds on the number of inter-node communications. Those bounds in turn allow D8 attributes to be processed...

We seek to conduct a comprehensive investigation of the dynamical mechanisms of vertical coupling over topography. • To construct a realistic model of the potential vorticity (PV) distribution on density layers across the Gulf Stream, generated from high-resolution density and velocity observations. • To demonstrate evidence of vertical coupling between the upper and lower layers in a hypothesi...
