Heterotic string models in which the space-time gauge symmetry is realized as a level k > 2 Kac-Moody algebra on the string world-sheet offer phenomenological features not present for the level k = 1 case (which includes all heterotic string models seriously considered to date). In particular, string models with N=l space-time supersymmetry and/or chiral matter fields can contain massless scala...

The first presenter, Professor Mariana Mazzucato (University of Sussex, UK), spoke about EU innovation policy in relation to risk taking and obtaining the return, and she challenged the common, but false, assumption that the public sector has a limited role in economic growth and innovation. The second presenter, technology writer Glyn Moody, focused on equitable licensing, open-source research...

We will show the Gauss decomposition with prescribed torus elements for a Kac-Moody group over a field in general case.

Moody's endorses the Basel Committee's proposal to use banks' internal risk assessments to re®ne the Basel Accord's risk weights on bank assets and commitments. External risk assessments, such as Moody's credit ratings, will likely play a supporting role as direct inputs into banks' internal rating systems and as tools for benchmarking and validating those systems. However, the widespread use o...

Mobile ad-hoc networks have attracted a great deal of attentions over the past few years. Considering their applications, the security issue has a great significance in them. Security scheme utilization that includes prevention and detection has the worth of consideration. In this paper, a method is presented that includes a multi-level security scheme to identify intrusion by sensors and authe...

The activity of the Ph.D. student Juri Luca De Coi involved the research field of policy languages and can be divided in three parts. The first part of the Ph.D. work investigated the state of the art in policy languages, ending up with ∙ identifying the requirements up-to-date policy languages have to fulfill ∙ defining a policy language able to fulfill such requirements (namely, the Protune p...

My romance with RNA began in Paris at the age of 21. After four undergraduate years at Caltech and before going to graduate school at MIT, I somehow managed to spend a miraculous year in the city of light, where I worked in the laboratory of Marianne Grunberg-Manago. She had done a post-doc with Severa Ochoa at NYU, where she discovered the enzyme polynucleotide phosphorylase (PNPase). This was...
