This paper describes three methods of creating a subliminal channel in visual cryptography that are defined for (2,2) sharing scheme. They work by hiding additional covert information besides the original encrypted image. The first is revealed when user folds share along specific axis. second encodes subpixels on basis message bits. It designed to hide wide range data types. third may be applie...

Previously we presented a TV-based super-resolution sharpening-demosaicing method. Our previous method makes it possible to restore frequency components higher than the Nyquist frequency, and to interpolate color signals effectively while preserving their sharp color edges, without producing ringing artifacts along the edges. However, since our previous method applies the TV regularization sepa...

Abstract We examine the robustness of color–color selection quiescent galaxies (QGs) against contamination dusty star-forming using latest submillimeter data. selected 18,304 QG candidates out to z ∼ 3 commonly adopted NUV – r J based on high-quality multiwavelength COSMOS2015 catalog. Using extremely deep 450 and 850 μ m catalogs from JCMT SCUBA-2 Large Programs, S2COSMOS STUDIES, as well Atac...

Zn doped GaN nanowires with different doping levels (0, <1 at%, and 3-5 at%) have been synthesized through a chemical vapor deposition (CVD) process. The effect of Zn doping on the defect evolution, including stacking fault, dislocation, twin boundary and phase boundary, has been systematically investigated by transmission electron microscopy and first-principles calculations. Undoped GaN nanow...

Low-temperature and ambient-temperature nonaqueous stacking techniques in capillary electrophoresis (CE) are described for the first time. A low-temperature bath was used to control the temperature from ambient to subzero degrees, by which a novel hyphenated method, low-temperature bath-nonaqueous capillary electrophoresis stacking (LTB-NACE stacking) is demonstrated. 3,4-Methylenedioxymethamph...

An ab initio method is used in a two state model to calculate consistent relative enthalpies and free energies for the stacking of nucleic acid bases in deoxyribose dinucleotides and the Watson-Crick hydrogen bonding interactions between mononucleotides when uncharged and singly charged. Favorable free energy changes are determined for the formation of dimers between mononucleotides by Watson-C...
