Of late, social tagging has become popular trend in information organisation. In context of digital resources the tags assigned by users also play vital role in information retrieval. For information discovery the ‘terms’ used to retrieve the results also depend upon the ‘relevancy’ or ‘weightage’ of the keywords. This study investigates ‘relevancy ranking’ of terms used in the full text of the...

When a set of coregulated genes share a common structural RNA motif, e.g. a hairpin, most motif search approaches fail to locate the covarying but structurally conserved motif. There do exist methods that can locate structural RNA motifs, like FOLDALIGN, but the main problem with these methods is that they are computationally expensive. In FOLDALIGN, a major contribution to this is the use of a...

A firm chooses a price and how much information to disclose about its product to a consumer whose tastes are unknown to the firm. Full disclosure of product information is always part of a sequential equilibrium when types are independent. In that case, a necessary and sufficient condition on equilibrium payoffs is that they are at least as high as those under full revelation for all product ty...
