We investigate the superposition strategy and its usefulness in terms of achievable information theoretic rates. The achievable rate of the superposition of block Markov encoding (decode-forward) and side information encoding (compress-forward) for the three-node Gaussian relay channel is analyzed. It is generally believed that the superposition can out perform decode-forward or compress-forwar...

Today, more and more DNA sequences are becoming available. The information about DNA sequences are stored in molecular biology databases. The size and importance of these databases will be bigger and bigger in the future, therefore this information must be stored or communicated efficiently. Furthermore, sequence compression can be used to define similarities between biological sequences. The s...

Abstract syntax trees (ASTs) have numerous advantages as a mobile code format over the more commonly used bytecode-based formats. Not only are ASTs portable, inherently safer, and more suitable for optimization, but we show that they also compress more densely. We have developed a prototype framework for AST compression, which we have used to compress Java programs. Our generic implementation r...

There has been a growing interest in recent years in developing real-time voice and fax communication software for use over the Internet. This paper discusses the design of an Internet Telephony Gateway (ITG) that is used to support the delivery of fax and/or voice services through the Internet to conventional telephones and fax machines on the Public Switched Telephone Network (PSTN). The inte...

When the ovaries have been removed, or when their vitality has been impaired by disease, the uterus is found senescent and small. 4. Pelvic inflammations, by causing, as Freund first indicated, condensation of the cellular tissues in the broad ligament, may impair the circulation in the uterine vessels, or, by producing adhesions around the uterus, as described by Jaquet, may compress the organ...

Transradial coronary angiography has been known as an alternative to the transfemoral approach with fewer serious complications. Radial artery pseudoaneurysms present as a rare complication of transradial catheterization. Although some methods have been applied for the obliteration of pseudoaneurysms, the use of radial bands such as the TR Band® (Terumo Medical Corporation, Somerset, NJ) is a n...

We applied the compress-and-shear reactive dynamics (CS-RD) simulation model to study the anisotropic shock sensitivity of cyclotrimethylene trinitramine (RDX) crystals. We predict that, for mechanical shocks between 3 and 7 GPa, RDX is most sensitive to shocks perpendicular to the (100) and (210) planes, whereas it is insensitive for shocks perpendicular to the (120), (111), and (110) planes. ...
