This paper considers modern secret-key block ciphers. The theory behind the design and analysis of modern block ciphers is explained, and the most important known attacks are outlined. Finally the Advanced Encryption Standard is discussed. 1 Block Ciphers Introduction In the last few thousands of years encryption algorithms, also called ciphers, have been developed and used [18,28]. Many of the...

same chemical stimulus and thereby attain their characteristic morphologies. Also included are observations of growing neurons from a mouse cerebellar mutant, and two papers on the role of nerve growth factor and laminin in determining the direction of neural elongation. The last section deals with a relatively new subspecialty, the electrophysiological study of the growth cone. It has long bee...

The present is unexpectedly a critical time for population change and policy. We are little more than half way through the great population growth spurt that began in the middle of the twentieth century, but developed-country governments seem to be losing interest in the issue. This loss of interest may have a significant demographic impact. The probable reasons for the declining interest are a...

INTRODUCTION More women are delaying child-bearing such that gynaecologists can no longer resort as frequently to definitive treatments, such as a hysterectomy, in the management of uterine fibroids. A review of newer conservative medical, radiological and surgical therapies and minimal access approaches to the organ-preserving myomectomy operation are discussed. MATERIALS AND METHODS Data fr...

The concept of dissociation was developed in the late 19th century by Pierre Janet for conditions of "double consciousness" in hypnosis, hysteria, spirit possession and mediumship. He defined dissociation as a deficit in the capacity of integration of two or more different "systems of ideas and functions that constitute personality", and suggested that it can be related to a genetic component, ...

R anolazine, a piperazine derivative sold under the trade name Ranexa, is a well-tolerated medication that selectively inhibits the late sodium current. Additionally, ranolazine has beneficial metabolic properties and does not affect heart rate or blood pressure. Ranolazine is currently approved in the United States and Europe as a second-line agent in the management of chronic stable angina pe...

This research aimed at identifying natural organisms and their properties in the technological samples of contemporary architecture. The main questionswere: "Which properties of natural organisms are effective on the technological works of contemporary architecture?" and "How much do they affect?"This descriptive-analytic research was conducted using archival method to access the theoretical...

The purpose of this research is to investigate the ability to redefine the components and indicators of popular architecture facades in contemporary architecture. The research method is content analysis and descriptive-analytic and survey with semiotic and Delphi technique. At first, popular architecture is analyzed using the descriptive and analytical method. Next, 14 components of the popular...
