The EXCYT facility (EXotics with CYclotron and Tandem) at the INFN-LNS is under completion and its commissioning with Li as the first radioactive beam is foreseen by the end of 2004. In the following, we report the work done with an emphasis on the measured yields and production efficiencies for 8, Li

A recently introduced double-base number representation has proved to be successful in improving the performance of several algorithms in cryptography and digital signal processing. The index-calculus version of this number system can be regarded as a two-dimensional extension of the classical logarithmic number system. This paper builds on previous special results by generalizing the number sy...

In Large Neighborhood Search (LNS), a problem is solved by repeatedly exploring (via tree search) a neighborhood of an incumbent solution. Whenever an improving solution is found, this replaces the current incumbent. LNS can improve dramatically the scalability of CP on large real world problems, provided a good neighborhood selection heuristic is available. Unfortunately, designing a neighborh...

– The quasienergy spectrum of a Bloch electron affected by dc-ac fields is known to have a fractal structure as function of the so-called electric matching ratio, which is the ratio of the ac field frequency and the Bloch frequency. This paper studies a manifestation of the fractal nature of the spectrum in the system “atom in a standing laser wave”, which is a quantum optical realization of a ...
