Let S be a finite set of n points in d-dimensional space. S is e.(n)-partitionable if there exists a set of d mutually intersecting hyperplanes that divide d-space into 2d open regions, no 2d 1 of which together contain more than o(n) points of S. Willard (1982) has shown that every set in 2-space is :n-partitionable. Yao (1983) has shown that every set in 3-space is gn-partitionable. It is sho...

The capability of a region to generate advanced technology, information and ultimately knowledge is regarded as the single most important force driving economic growth. This paper provides benchmarks for the innovation performance of manufacturing businesses in the three NUTS 2 regions of Ireland (Border Midlands & West, South & East, Northern Ireland) in 1999, just prior to the start of the cu...

We have isolated from a lambda gt10 cDNA library a clone lambda GTH4 which encodes a human liver glutathione S-transferase Hb subunit, designated as subunit 4. Expression of this cDNA in E. coli and subsequent purification and immunoblotting analysis provided a definitive assignment of a structure and function relationship. RNA blot hybridization with human liver poly(A) RNA revealed a single b...

Red clover necrotic mosaic virus (RCNMV) is a member of the genus Dianthovirus and has a bipartite positive-sense genomic RNA with 3' ends that are not polyadenylated. In this study, we show that both genomic RNA1 and RNA2 lack a 5' cap structure and that uncapped in vitro transcripts of RCNMV RNA1 replicated to a level comparable to that for capped transcripts in cowpea protoplasts. Because th...

The beet armyworm, Spodoptera exigua Hübner (Lepidoptera: Noctuidae) is a serious agricultural pest worldwide. However, population sources of S. exigua in outbreak regions are still vague due to the lack of understanding the distribution of overwintering regions, especially in China. In the present study, the potential overwintering regions of S. exigua in China are projected using the method o...

Deep sequencing was implemented to study the transcriptional landscape of Mycobacterium avium. High-resolution transcriptome analysis identified the transcription start points for 652 genes. One third of these genes represented leaderless transcripts, whereas the rest of the transcripts had 5' UTRs with the mean length of 83 nt. In addition, the 5' UTRs of 6 genes contained SAM-IV and Ykok type...

The wealth of comparative genomics data from yeast species allows the molecular evolution of these eukaryotes to be studied in great detail. We used "proximity plots" to visually compare chromosomal gene order information from 14 hemiascomycetes, including the recent Génolevures survey, to Saccharomyces cerevisiae. Contrary to the original reports, we find that the Génolevures data strongly sup...

The three plus-strand genomic RNAs of Alfalfa mosaic virus (AMV) and the subgenomic messenger for viral coat protein (CP) contain a 5'-cap structure, but no 3'-poly(A) tail. Binding of CP to the 3' end of AMV RNAs is required for efficient translation of the viral RNAs and to initiate infection in plant cells. To study the role of CP in translation, plant protoplasts were transfected with lucif...
