Cross pairingof select and data voltages without compromising the selectionratio generates more rms voltages as compared to SAT. Grayscalescan be displayed with less number of voltages in the addressingwaveforms and less number of time intervals in a cycle as comparedto SAT by cross pairing of select voltages with data voltages.Better brightness uniformity among pixels that are driven to samegrayscale can be achieved by cross pairing because the width ofthe select pulses increases due to less number of time intervalsin a cycle as compared to SAT. About 50% reduction in numbervoltages in row waveforms and column waveforms in addition toa 50% reduction in number of time intervals in a cycle can beachieved as compared to SAT by cross pairing select and data voltages<br/><br/>Description: Restricted Access.

Thermophysical propertiesof these liquid crystal nanocomposites were investigated by UV-Visspectroscopy, photoluminescence spectroscopy, differential scanningcalorimetry, polarizing optical microscopy, DC conductivity andsmall angle X-ray diffraction.<br/><br/>Description: Open access Mon, 03 Oct 2011 22:58:59 GMT http://hdl.handle.net/2289/4219 Title: Multispecies model with interconversion, chipping, and injection<br/><br/>Authors: Sachdeva, Himani; Barma, Mustansir; Rao, Madan<br/><br/>Abstract: Motivated by the phenomenology of transport through the Golgi apparatus of cells, we study a multispecies model with boundary injection of one species of particle, interconversion between the different species of particle, and driven diffusive movement of particles through the system by chipping of a single particle from a site. The model is analyzed in one dimension using equations for particle currents. It is found that, depending on the rates of various processes and the asymmetry in the hopping, the system may exist either in a steady phase, in which the average mass at each site attains a time-independent value, or in a “growing” phase, in which the total mass grows indefinitely in time, even in a finite system. The growing phases have interesting spatial structure. In particular, we find phases in which some spatial regions of the system have a constant average mass, while other regions show unbounded growth.<br/><br/>Description: Open Access Mon, 29 Aug 2011 22:58:59 GMT
