Index matching of guided modes in birefringent multilayered organic waveguides opens new prospects for the design of mode coupling and mode switching devices. We demonstrate index matching of guided modes in two multilayered structures, in (a) a PTCD

Traditional surveys provide estimates that are based only on the sample observations collected for the population characteristic of interest. However, these estimates may have unacceptably large variance for certain domains. Small Area Estimation (SA

Many empirical studies have been carried out in developed and emerging markets using methods to account for extreme market risk. A front-runner in the methods used is Extreme Value Theory (EVT). In this study, these methods are applied to the All Sha

Standard statistical techniques do not provide methods for analyzing data from nonreplicated factorial experiments. Such experiments occur for several reasons. Many experimenters may prefer conducting experiments having a large number of factor level

We report on the intensity dependent exciton dynamics in optically excited tris (8-hydroxyquinoline) aluminum (Alq 3 ) films grown by organic molecular beam epitaxy that show a strong quenching of light emission at low temperature. We further report

We investigate the light emission of optically excited tris(8-hydroxyquinolinato) aluminum (Alq${}_{3}$) films by temperature-dependent, time-integrated, as well as time-resolved photoluminescence (PL) at various photon densities. The Alq${}_{3}$ fil

We investigate the mode properties of planar dielectric aluminum-quinoline (Alq3) multilayer waveguides comprising one single or three equally spaced embedded nanometer-thin (∼10 nm thick) Alq3-Mg0.9:Ag0.1 composite metal-island layers. The plasmon

In the absence of replication, conventional analyses do not provide ways to examine three-way interaction in threeway experiments. Tucker3 analysis based on alternating least squares algorithm is a general approach that can be used in such cases. How
