In this paper, we present a sufficient condition for the universal rigidity of a generic bar framework G(p) in terms of the Gale matrix Z corresponding to G(p). We also establish a relationship between the stress matrix S and the Gale matrix Z for bar frameworks. This allows us to translate back and forth between S and Z in recently obtained results concerning universal rigidity, global rigidit...

Certain Gram-positive bacteria have the ability to concentrate certain amino-acids in the free state within the cell (Gale, 1947; Taylor, 1947). Aminoacids may pass across the cell wall either by a process of diffusion, as in the case of lysine which becomes concentrated within the cell by a form of Donnan effect (Najjar & Gale, 1950), or as a result of an active transfer which requires energy ...

We describe the large vocabulary automatic speech recognition system developed for Modern Standard Arabic by the SRI/Nightingale team, and used for the 2007 GALE evaluation as part of the speech translation system. We show how system performance is affected by different development choices, ranging from text processing and lexicon to decoding system architecture design. Word error rate results ...

In the previous lectures we discussed Bayesian martingale models; in these two lectures we turn our attention to non-martingale learning models. We first look at a Bayesian model introduced by Gale and Kariv [2], and then briefly discuss the special case of the Gale-Kariv model on the complete graph, as analyzed by Mossel and Tamuz [6]. Next, we study heuristic models of repeated voting: we fir...

Recently there have been numerous studies exploring the benefits of the coalition formation in a cognitive radio network and it has been shown that coalition formation tends to improve the performance of cognitive radio. In this paper we use the concepts from matching theory, specifically we use Gale-Shapley algorithm, to form the coalition among cognitive radio user for collaborative spectrum ...
