Steganography is the approach for hiding any secret message in a variety of multimedia carriers like images, audio or video files. Whenever we are hiding a data, it is very important to make it invisible, so that it could be protected. A number of steganographic algorithms have been proposed based on this property of a steganographic system. This paper concentrates on integrating Tri way pixel ...

Recently, the data hiding method based on the high embedding capacity by using improved EMD method was proposed by Kuo et al.[6]. They claimed that their scheme can not only hide a great deal of secret data but also keep high safety and good image quality. However, in their scheme, the sender and the receiver must share the synchronous random secret seed before they transmit the stego-image eac...

In the framework of Lorentz symmetry breaking (LSB), we investigate quasinormal modes (QNMs) and greybody factors (GFs) Kerr-like black hole spacetime obtained from bumblebee gravity model. particular, analyze scalar fermionic perturbations within both semi-analytic WKB method time domain approach. The impacts LSB on bosonic/fermionic QNMs GFs are investigated in detail. results graphically dep...

The rotation curves of low surface brightness (LSB) galaxies suggest that they possess significantly higher mass-to-light (M/L) ratios than their high surface brightness counterparts, indicating that LSB galaxies may be dark matter dominated. This interpretation is hampered by the difficulty of disentangling the disc and dark halo contributions from the disc dynamics of LSB galaxies. Recently, ...

We investigate the star formation history and chemical evolution of low surface brightness (LSB) disk galaxies by modelling their observed spectro-photometric and chemical properties using a galactic chemical and photometric evolution model incorporating a detailed metallicity dependent set of stellar input data. For a large fraction of the LSB galaxies in our sample, observed properties are be...

The dentate gyrus (DG) is one of two areas in the mature brain where stem cells reside to continuously produce new neurons throughout adulthood. While much research has focused on the DG for its roles in adult neurogenesis, little is known regarding how this key region of the brain initially develops to form its distinct architecture. We show here that the murine EphB2 receptor tyrosine kinase ...

We present deep Near–Infrared (NIR) imaging of Blue Compact Dwarf Galaxies (BCDs), allowing for the first time to derive and systematize the NIR structural properties of their stellar low–surface brightness (LSB) host galaxies. Compared to optical data, NIR images, being less contamined by the extended stellar and ionized gas emission from the starburst, permit to study the LSB host galaxy clos...

Abstract A 33.6 ps LSB Time-to-Digital converter was designed in 130 nm BiCMOS technology. The core of the is a differential 9-stage ring oscillator, based on multi-path architecture. novel version this design proposed, along with an analytical model linearity. allowed us to understand source performance superiority (in terms linearity) our and predict further improvements. oscillator integrate...

A steganographic method called adjacent bin mapping (ABM) is presented. Firstly, it is applied to 3D geometries by mapping the coordinates within two adjacent bins for data embedding. When applied to digital images, it becomes a kind of LSB hiding, namely the LSB algorithm. In order to prevent the detection using a metric named histogram tail, the hiding is performed in a pseudorandom order. Th...
