A simplified interaction potential for protein folding studies at the atomic level is discussed and tested on a set of peptides with approximately 20 residues each. The test set contains both alpha-helical (Trp cage, F(s)) and beta-sheet (GB1p, GB1m2, GB1m3, Betanova, LLM) peptides. The model, which is entirely sequence-based, is able to fold these different peptides for one and the same choice...

We compared three methods for presenting stimuli during reinforcer-preference assessments: a paired-stimulus format (PS), a multiple-stimulus format in which selections were made with replacement (MSW), and a multiple-stimulus format in which selections were made without replacement (MSWO). Results obtained for 7 participants showed moderate to high rank-order correlations between the MSWO and ...

We study some specializations and extensions of the quantum version of the MacMahon Master Theorem derived by Garoufalidis, Lê and Zeilberger. In particular, we obtain a (t, q)-analogue for the Cartier-Foata noncommutative version and a semi-strong (t, q)-analogue for the contextual algebra.

In this paper, we propose automatic generation of bus-based communication architectures from an abstract model reflecting only the communication topology. Tasks include protocol selection for each bus, master/slave assignment for each component, interrupt handling and addressing for synchronization between components, and arbitration to resolve multiple accesses on a bus. We present a set of ex...

We show that the large mixing between νµ and ντ observed by the SuperKamiokande collaboration is a quite natural prediction in a large class of seesaw models. This large mixing is basically due to the unparallel family structure suggested from the observed mass hierarchies in quark and lepton mass matrices. We show that the unparallel family structure is automatically realized in " coset-space ...

Resource selection is fundamental to the performance of master/slave applications. In this paper, we address the problem of promoting performance for distributed master/slave applications targeted to distributed, heterogeneous ”Grid” resources. We present a work-rate-based model of master/slave application performance which utilizes both system and application characteristics to select potentia...

A longitudinal study found that the psychological approach individuals take when immersed in a general multicultural environment can predict subsequent career success. Using a culturally diverse sample, we found that ‘‘multicultural engagement’’—the extent to which students adapted to and learned about new cultures—during a highly international 10-month master of business administration (MBA) p...
