AB: We performed shear-wave splitting of core phases using a subset of 33 selected events within an array composed of 48 broadband stations that spans a 650x350 km area crossing the Lhasa and the southern part of the Qiangtang terranes. Our results reveal the presence of azimuthal anisotropy with small-to-moderate delay times (0.5-1.4s). The consistency of the splitting parameters with respect ...

The influence of compound noun splitting on a German-Polish bilingual vocabulary extraction task is investigated. To accomplish this, several unsupervised methods for increasingly accurate compound noun splitting are introduced. Bilingual evidence from a parallel German-Polish corpus and co-occurrence counts from the web are used to disambiguate compound noun analyses directly. These collected ...

INTRODUCTION Time-resolved 3-dimensional phase-contrast MR imaging (3D-PC MRI) has developed as an active area of research for vascular imaging [1]. The ability to acquired directional flow information along all three principle axes has led to investigations of the role of altered hemodynamics in vascular pathologies[2], quantification of flow in the major intracranical vessels [3], and researc...

The arylidienes of spiro thiazolidines (5) containing α,β-unsaturated function have been used as component of Micheal addition with equimolar amount of 2-aminopyridine (6a) to give novel spiro [indole-3,2′-pyrido[1,2-a]thiazolo[5,4-e]pyrimidines] (7) in a single step under microwaves in presence of montmorillonite KSF as solid support. The new improved synthetic method for spiro [indole-3, 2′-t...

In binary classification, imbalance refers to situations in which one class is heavily under-represented. This issue due either a data collection process or because indeed rare population. Imbalanced classification frequently arises applications such as biology, medicine, engineering, and social sciences. this paper, for the first time, we theoretically study impact of sizes on linear discrimin...

This study is about the non-uniform electric field for splitting of water in oil emulsion. If the process occurs in an inhomogeneous electrical field, the drops are polarized and then their mobility is increased. The emulsion drops will be charged and move toward the central point of splitter where the maximum intensity of electrical field has been concentrated. In this process, the drops encou...

Titania nanotubes (TNT) prepared by anodization of Ti foils were used for water splitting in a standalone cell. The concentration polarization between the anode side (1M NaOH) and cathode side (0.5 M H2SO4) ensured that the water splitting reaction could take place with no external bias and separate H2 and O2 evolution could be achieved. The destructi...
