DIRS: Disconnected Information Retrieval System

The World Wide Web gives individuals access to huge amounts of data. This includes access to information also found in traditional formats such as news copy. This study addresses a desire to blend these two mediums in such a way that media consumers can move transparently from a hard copy of a given article to an electronic copy. Document retrieval experiments were performed in an attempt to de...

Program Performance Michelle

Many scienti c applications require sparse matrix computations. For example, Finite Element modeling and N-body simulations. It is di cult to write these codes in a portable way which also achieves high performance because of the sparsity of the matrices and because current architectures have deep memory hierarchies and multiple levels of parallelism. Therefore the implementation of such comput...

DIRS and Ngaro Retrotransposons in Fungi

Retrotransposons with a tyrosine recombinase (YR) have been discovered recently and lack thorough annotation in fungi. YR retrotransposons are divided into 3 groups: DIRS, Ngaro and VIPER (known only from kinetoplastida). We used comparative genomics to investigate the evolutionary patterns of retrotransposons in the fungal kingdom. The identification of both functional and remnant elements pro...

Valentina Greco: Got hair?

I n mammalian hair follicles, follicu-lar tissues and new hairs are generated during a cyclical growth cycle. The growth phase is followed by a period of degeneration and then by entry into a resting state that terminates with a new round of growth. The transitions between different stages of the cycle are triggered by interactions of hair follicle stem cells with underlying mesenchymal cells, ...
