The Carina dSph galaxy: where is the edge?
G. Bono, M. Monelli, A. R. Walker +13
Recent cosmological N-body simulations suggest that current empirical estimates of tidal radii in dSphs might be underestimated by at least one order of magnitude. To constrain the…
Corpus-based Learning of Analogies and Semantic Relations
Peter D. Turney, Michael L. Littman
We present an algorithm for learning from unlabeled text, based on the Vector Space Model (VSM) of information retrieval, that can solve verbal analogy questions of the kind found…
Measuring Semantic Similarity by Latent Relational Analysis
Peter D. Turney
This paper introduces Latent Relational Analysis (LRA), a method for measuring semantic similarity. LRA measures similarity in the semantic relations between two pairs of words. Wh…
Self-organization of gene regulatory network motifs enriched with short transcript's half-life transcription factors
Edwin Wang, Enrico Purisima
Network motifs, the recurring regulatory structural patterns in networks, are able to self-organize to produce networks. Three major motifs, feedforward loop, single input modules…
Realization of a Laser Cooled Microwave Power Standard (conference digest)
David C. Paulusse, Nelson L. Rowell, Alain Michaud
We demonstrate the feasibility of a novel microwave power standard based on the electromagnetic interaction with cold atoms. Under the effect of the radiation, the internal state p…
