Mining a multilingual association dictionary from Wikipedia for cross-language information retrieval
The Wikipedia is characterized by its dense link structure and a huge amount of articles in different languages, which make it a notable Web corpus for knowledge extraction and mining, in particular for mining the multilingual associations. In this paper, motivated by a psychological theory of word meaning, we propose a graphbased approach to constructing a cross-language association dictionary...
In the present work, a theoretical analysis of the first-order of stimulatedBrillouin scattering (SBS) in a double-clad (DC) ytterbium (Yb)-doped silica fiber laserin unidirectional pumping mode is presented.An accurate simulation for calculating SBS nonlinearity is performed by considering thecoupled differential rate equations for pump, signal and Stokes powers, as wel...
A factor that limits the use of multiphoton microscopy (MPM) in clinical and preclinical studies is the lack of a compact and flexible probe. We report on a miniaturized MPM probe employing a microelectromechanical system (MEMS) scanning mirror and a double-clad photonic crystal fiber (DCPCF). The use of a MEMS mirror and a DCPCF provides many advantages, such as size reduction, rapid and preci...
RATIONALE Since the pathogenesis of chronic lung allograft dysfunction (CLAD) remains poorly defined with no known effective therapies, the identification and study of key events which increase CLAD risk is a critical step towards improving outcomes. We hypothesized that bronchoalveolar lavage fluid (BALF) CXCR3 ligand concentrations would be augmented during organizing pneumonia (OP) and that ...
