Three questions on duo rings

Quasi-Duo Rings and Stable Range Descent

In a recent paper, the first author introduced a general theory of corner rings in noncommutative rings that generalized the classical theory of Peirce decompositions. This theory is applied here to the study of the stable range of rings upon descent to corner rings. A ring is called quasi-duo if every maximal 1-sided ideal is 2-sided. Various new characterizations are obtained for such rings. ...

Three questions on Lorentz violation

We review the basics of the two most widely used approaches to Lorentz violation the Standard Model Extension and Noncommutative Field Theory and discuss in some detail the example of the modified spectrum of the synchrotron radiation. Motivated by touching upon such a fundamental issue as Lorentz symmetry, we ask three questions: What is behind the search for Lorentz violation? Is String Theor...

A Fast Implementation of etaT Pairing in Characteristic Three on Intel Core 2 Duo Processor

We present an efficient implementation of ηT pairing on Intel Core 2 Duo processor. The processing speed of our implementation achieves 92 μsec over F 3 and 553 μsec over F 3 on 2.6GHz processor.

Deadly duo

An astonishing one-third of the world’s population is infected with the bacterium that causes tuberculosis (TB), Mycobacterium tuberculosis. In most people it remains inactive or latent but in about 10% of people an active case of TB disease will develop within their lifetime. Simple antibiotics can prevent and treat most of these cases, yet 8-10 million people develop an active TB infection an...
