    Description: The broadcast nature of wireless transmissions is a two-edged sword for wireless broadcasting. On one hand, it makes broadcasting much more efficient; on the other hand, it causes concurrent transmissions much more likely to collide, deteriorating throughput and delay. In this paper, we propose a novel PHY layer technique called onion decoding, which enables correct decoding of two or more colliding transmissions. Thus, more concurrent transmissions can be scheduled, leading to improved throughput and delay. As we shall see in the paper, achieving optimal broadcast throughput and delay, with and without onion decoding, are non-trivial in multi-rate wireless networks. No efficient algorithm is known. We propose a simple heuristic algorithm for wireless broadcasting using onion decoding, and evaluate its performance through simulations. Simulation results confirm that onion decoding can significantly improve throughput and delay of wireless broadcasting.

    Description: Molecular sequences that share a high degree of similarity often are thought to have evolved from common ancestral genes. Closely related protein sequences will presumably correspond to similar three-dimensional structures and conserved biological functions (although the reverse is not necessarily true: similar structures and conserved functions do not imply that the corresponding protein sequences will be similar; reviewed in ref. 1). These assumptions provide the basis for computational gene annotation. Typically, the first step in characterizing a novel gene is to compare its sequence against known sequences in available databases and to predict its origin and function by copying the annotation of those previously characterized sequences. This approach has been highly successful and is probably the only practical method applicable to large-scale annotation efforts at present. It should be pointed out, however, that this practice is not without its limitations (and is also unsatisfactory from the more theoretical perspective of those who wish to determine structure and function from primary sequence; for a provocative editorial on this subject, see ref. 2). The intrinsic problems of transitive propagation of historical annotation errors have been discussed elsewhere (bi3) and are all too familiar to any biologist who has looked into the databases only to find puzzling annotations that make no sense with current knowledge.
