Big Hits

T here aren't many sports articles in the journal Science, so it was with great interest that I read " A Late Hit for Pro-Football Players " by Greg Miller (www. sciencemag.org). 3 This article is a very interesting compilation of recent research and developments in the area of sports-related concussion. The article highlights the efforts of Chris Nowinski, a former Harvard football standout wh...

HITS and Misses: Combining BM25 with HITS for Expert Search

This paper describes the participation of Dublin City University in the CriES (Cross-Lingual Expert Search) pilot challenge. To realize expert search, we combine traditional information retrieval (IR) using the BM25 model with reranking of results using the HITS algorithm. The experiments were performed on two indexes, one containing all questions and one containing all answers. Two runs were s...

Two hits revisited again.

INTRODUCTION AND METHODS Since the concept of the "two hit hypothesis" was introduced over 20 years ago, a wealth of genetic data has accumulated on the mutations found at tumour suppressor loci. Perhaps surprisingly, these data conceal large gaps in our knowledge which genetic and functional studies are beginning to uncover. The "two hit hypothesis" must be updated to take account of this new ...

Hybrid Rocket Propulsion Technology for Sounding Rocket Development

Hybrid combustion technology has recently been employed in the sounding rocket developments to support the science experiments of academic applications and the establishment of a viable flight test platform for space components development. Due to its safety nature in material handling and combustion processes, hybrid rockets are suitable for university and research institute environments for a...
