A vapochromic luminescent crystal consisting of boron diiminate has been discovered. The emission color is changed by absorption solvent vapor, such as dichloromethane and recovered desorption encapsulated molecules through fuming with another cyclohexane. alteration molecular conformation between planar twisted structures responsible for luminochromism. More information can be found in the Ful...

We compare the dependences on the number of colors of the leading scattering amplitudes using the single index quark field and two index quark fields. These are seen to have different relationships to the scattering amplitudes suggested by chiral dynamics which can explain the long puzzling pion pion s wave scattering up to about 1 GeV. This may be interesting for getting a better understanding...

This paper presents a fast and efficient way for color reindexing that tends to maximize the compression performance of a palette-based compression system. The proposed scheme relates the index difference of neighboring pixels to the potential cost of bits. It optimizes the assignment of index values to colors in a one-step look-ahead greedy fashion. Experimental results suggest that the propos...

We propose and demonstrate weak-microcavity organic light-emitting diode (OLED) displays with improved light-extraction and viewing-angle characteristics. A single pair of low- and high-index layers is inserted between indium tin oxide (ITO) and a glass substrate. The electroluminescent (EL) efficiencies of discrete red, green, and blue weak-microcavity OLEDs are enhanced by 56%, 107%, and 26%,...

the increasing tendency for health oriented products caused considerable research has studied on increase and maintaining quality of different products. sponge cake is one of the cereal products which itsmain problems arereterogradation and lack of soluble dietary fibers which has many health benefits. in this research, therefore, the effects of adding oat β-d-glucan on the physical properties ...

The paper presents the color image segmentation based on rough-set approach has been proposed. The color image segmentation is one of the most challenging tasks particularly in the area of image analysis, computer vision, and pattern recognition. In this paper, the proposed algorithm based on roughness index to calculate the peaks and valleys values. Based on peak and valley values to achieve b...

Combined surface, structural and opto-electrical investigations are drawn from the chemically fashioned ZnO nanotubes and its heterostructure with p-GaN film. A strong correlation has been found between the formation of radiative surface defect states in the nanotubes and the pure cool white light possessing averaged eight color rendering index value of 96 with appropriate color temperature. Hi...
