This paper devotes itself to the study of secret message delivery using cover image and introduces a novel steganographic technique based on genetic algorithm to find a near-optimum structure for the pair-wise least-significant-bit (LSB) matching scheme. A survey of the related literatures shows that the LSB matching method developed by Mielikainen, employs a binary function to reduce the numbe...

Divina Commedia represents Dante’s most famous work: even if many centuries have passed, it still universal knowledge. Today comics are perceived as consumer literature, however over time there been works that reinterpreted in various ways Commedia. Various reinterpretations conducted using interwined and different languages. Reinterpretations accompany Dante's world today's world.

In this paper I analyze two contemporary works of interactive fiction (IF), Nick Montfort’s Ad Verbum and Emily Short’s City of Secrets, as examples of two contrasting ways in which IF reacts to the perceived threat of computer graphics. In the postcommercial era of IF, graphics represent a factor that, without being acknowledged, has profoundly shaped the development of the medium. Post-graphi...

AIMS To test the bactericidal activity of standard organ culture medium, and to compare the sensitivity and rapidity of blood culture bottles with conventional microbiological methods for detection of bacteria and fungi inoculated in a standard cornea organ culture medium. METHODS The bactericidal activity of contaminated standard organ culture medium containing 100 IU/ml penicillin, 0.1 mg/m...

Porous media like air-saturated polymer foams with open cells, have a nontrivial frequency-dependent absorption that arises due to viscous and thermal effects at the scale of the rigid frame microstructure. In order to produce multiple scattering at ultrasonic frequencies, mesoscale scatterers are introduced in the porous medium host. The effective wave number of such a multiscale medium should...

BACKGROUND Dialogue is a foundational feature of social life and an important way in which we come to understand one another. In situations of controversy dialogue is often absent because of a range of social barriers. We have developed a new film-based qualitative research method for studying controversial issues in healthcare and social policy. We call this method Brokered Dialogue. Theoretic...

introduction: neuro-plasticity is the neuronal system ability to modify and recover itself after the occurrence of impairment and injuries. following the abolition of a sensory modality, modifications will be applied to other modalities and their cortical function in a way that the processing of these modalities not only will happen in their own specific cortical area, but also in those areas t...
