Frequency dispersion studies on proton spin-lattice relaxation rates of a liquid crysal (4’-octyloxy-4-cyanobiphenyl) embedded in Aerosil matrix show significant increase at low frequencies (sub-MHz regime) relative to the bulk sample, and are interpreted as primarily due to slow reorientations near the surface ordered layers mediated by translation displacements. The computed exponent in the p...
When communication is required between systems that support different interfaces is required, a detailed study of driver output and receiver input characteristics is required to determine if direct “electrical” inter-operation is possible. The results of this study may also conclude that some translation devices are required for inter-operation. This may include passive devices or active device...
INTRODUCTION The 2015 WHO recommendation of antiretroviral therapy (ART) for all HIV-positive persons calls for treatment initiation in millions of persons newly eligible with high CD4+ counts. Efficient and effective care models are urgently needed for this population. We evaluated clinical outcomes of asymptomatic HIV-positive adults and children starting ART with high CD4+ counts using a nov...
We examine the fair allocation of the construction costs among the buyers of units located on different stories of a building. The rationale for the diverse allocation of the costs is two fold: from a supply perspective, the higher the story is, the greater the inflexibility it imposes on the entrepreneur due to the accompanying commitment to build all stories underneath; from a demand viewpoin...
The effects of dispersed aerosil nanoparticles on two of the phase transitions of the thermotropic liquid-crystal material 4-n-pentylphenylthiol-4(')-n-octyloxybenzoate (8;S5) have been studied using high-resolution x-ray diffraction techniques. The aerosils hydrogen bond together to form a gel which imposes a weak quenched disorder on the liquid crystal. The smectic-A fluctuations are well cha...
