We retrospectively evaluated 12 patients with histologically verified central neurocytoma (CN) to identify the MRI characteristics associated with this tumour. All tumours had heterogeneous signal intensity in their solid components and seven had a "soap bubble" or spongy appearance. Spicules were identified at the tumour periphery interfacing with the lateral ventricular walls. These spicules ...

In this paper, load-carrying capacity in steel shear wall (SSW) was estimated using artificial neural networks (ANNs). The SSW parameters including load-carrying capacity (as ANN’s target), plate thickness, thickness of stiffener, diagonal stiffener distance, horizontal stiffener distance and gravity load (as ANN’s inputs) are used in this paper to train the ANNs. 144 samples data of each of th...

Abstract Shear walls are critical in designing of reinforced concrete structures against lateral loads. Although various research studies have been conducted on the design shear walls, these were limited by laboratory capacity. This led to inability testing with their full height for high mid-rise walls. Fortunately, progress specimen modeling techniques permitted performing scaled experimental...

COVER Confocal light microscopy image of a lateral root emerging from the main root (width: ~130 to 150 micrometers) of a young Arabidopsis thaliana plant (green, nuclei; red, cell walls). Lateral roots initiate deep within the primary (“mother”) root. Their emergence from the mother root is a highly regulated process requiring adjacent cells to shrink and make way for the developing lateral ro...

background abnormalities in the velocity and pattern of myocardial shortening on tissue doppler imaging (tdi) have been proposed to aid in the noninvasive diagnosis of coronary artery disease (cad). objectives we investigated the diagnostic value of post-systolic shortening (pss), a delayed ejection velocity of the myocardium after the closure of the aortic valve, on tdi in the diagnosis of cad...

Goals of this preliminary study are to better understand (1) earthquake performance of wood-frame shear walls carrying gravity loads, compared with walls without gravity load, and (2) performance of walls subjected to a sequence of earthquake motions, compared with walls subjected to a single earthquake. Tests with simulated earthquake ground motions were conducted on 2,440 by 2,440-mm (8 by 8-...
