We numerically and experimentally show the existence of multicolor vector spatial solitons in a Kerr planar waveguide through the combined effects of cross-phase modulation, four-wave mixing, and stimulated Raman scattering. Mutual spatial guiding of the Raman-Stokes, anti-Stokes, and pump waves is achieved in the high-conversion regime mainly by cross-phase modulation and phase-matched four-wa...

mutual funds are the best tool to mobilize savings and investments in an economy and pakistan is the pioneer in south asia, but this industry is not as much mature in comparison to its age in pakistan. this paper examines the performance of closed ended mutual funds in pakistan by using five different ranking measures during a period of january 2009 to december 2013 and the sample consists of o...

Despite the size and importance of separately managed accounts (SMAs) and collective investment trusts, their characteristics and performance have not been studied in detail. We show that separate account performance is similar to that of index funds and superior to that of actively managed mutual funds. Management supplies a benchmark for each separate account. When the management-selected ben...

This paper describes a method for extracting translations of terms across languages, using parallel corpora. The extracted term correspondences are such that they are useful when performing query expansion for cross language information retrieval, or for bilingual lexicon extraction. The method makes use of the mutual information measure and allows for mapping between single wordto multi-word t...

As interconnect line width and spacing decreases and operating clock rate increases, interconnect has become a bottleneck in developing high-speed integrated circuits, multichip modules, printed circuit boards, and systems. With small line spacing, mutual capacitance and inductance approach the level of self-capacitance and inductance, and can severely degrade signal integrity. The well-known e...
