to evaluate the effect of different light intensities on the degree of conversion (dc) of dual-cured resin cement at different depths of translucent fiber posts.thirty translucent fiber posts were randomly assigned into three (n=10) groups. they were cemented in the simulated canal spaces using duo-link dual-cured resin cement. the cement was light-cured under 600, 800 and 1100 mw/cm(2) light i...

This paper describes comparison and analysis of state-of-theart lossless image compression algorithms for light field mask data that are very useful in transmitting and refocusing the light field images. Recently, light field cameras have received wide attention in that they provide 3D information. Also, there has been a wide interest in studying the light field data compression due to a huge l...

Photochromic switches that are able to transmit information in a quick fashion have attracted a growing interest within materials science during the last few decades. Although very fast photochromic switching materials working within hundreds of nanoseconds based on other chromophores, such as spiropyranes, have been successfully achieved, reaching such fast relaxation times for azobenzene-base...

Plants dissipate excess excitation energy as heat by non-photochemical quenching (NPQ). NPQ has been thought to resemble in vitro aggregation quenching of the major antenna complex, light harvesting complex of photosystem II (LHC-II). Both processes are widely believed to involve a conformational change that creates a quenching centre of two neighbouring pigments within the complex. Using recom...
