Here we employ both dynamic and geometric phase control of light to produce radially modulated vector-vortex modes, the natural modes of optical fibers. We then measure these modes using a vector modal decomposition set-up as well as a tomography measurement, the latter providing a degree of the non-separability of the vector states, akin to an entanglement measure for quantum states. We demons...
In this paper, a high-accuracy and high-speed 2D 8x8 Discrete Cosine Transform (DCT) design is proposed. By using the parallel architecture, inherited from the design reported by S. Ramachandran et. al., re-designing and enhancing function of all component modules, the proposed design can transform each 8x8 block in 64 cycles and achieve a very high accuracy compared to other designs and standa...
The present study is undertaken to predict the three dimensional structure of γ-Hexachlorocyclohexane dehydrochlorinase (linA) in Sphingomonas paucimobilis UT26. γ-Hexachlorocyclohexane dehydrochlorinase (linA) catalyzes the initial steps in the biotransformation of the important insecticide γhexachlorocyclohexane (γ-HCH) by the soil bacterium Sphingomonas paucimobilisUT26. Stereo chemical anal...
Starting with the experiments of Ramachandran and Gregory (Nature, 275, 55-56, 1978), several psychophysical studies in apparent motion (AM) have established that the perception of motion is significantly impaired at equiluminance. Still debated, however, is whether color alone can resolve ambiguities in AM. We report here on several psychophysical experiments, the quantitative results of which...
