Higher dimensional flat embeddings of black strings in (2+1) dimensions

We obtain (3+1) and (3+2) dimensional global flat embeddings of (2+1) uncharged and charged black strings, respectively. In particular, the charged black string, which is the dual solution of the Banados-Teitelboim-Zanelli black holes, is shown to be embedded in the same global embedding Minkowski space structure as that of the (2+1) charged de Sitter black hole solution.Comment: 11 pages, REVTEX, no figur

BAC library resources for map-based cloning and physical map construction in barley (Hordeum vulgare L.)

Background: Although second generation sequencing (2GS) technologies allow re-sequencing of previously gold-standard-sequenced genomes, whole genome shotgun sequencing and de novo assembly of large and complex eukaryotic genomes is still difficult. Availability of a genome-wide physical map is therefore still a prerequisite for whole genome sequencing for genomes like barley. To start such an endeavor, large insert genomic libraries, i.e. Bacterial Artificial Chromosome (BAC) libraries, which are unbiased and representing deep haploid genome coverage, need to be ready in place. Result: Five new BAC libraries were constructed for barley (Hordeum vulgare L.) cultivar Morex. These libraries were constructed in different cloning sites (HindIII, EcoRI, MboI and BstXI) of the respective vectors. In order to enhance unbiased genome representation and to minimize the number of gaps between BAC contigs, which are often due to uneven distribution of restriction sites, a mechanically sheared library was also generated. The new BAC libraries were fully characterized in depth by scrutinizing the major quality parameters such as average insert size, degree of contamination (plate wide, neighboring, and chloroplast), empty wells and off-scale clones (clones with 250 fragments). Additionally a set of gene-based probes were hybridized to high density BAC filters and showed that genome coverage of each library is between 2.4 and 6.6 X. Conclusion: BAC libraries representing >20 haploid genomes are available as a new resource to the barley research community. Systematic utilization of these libraries in high-throughput BAC fingerprinting should allow developing a genome-wide physical map for the barley genome, which will be instrumental for map-based gene isolation and genome sequencing.Daniela Schulte, Ruvini Ariyadasa, Bujun Shi, Delphine Fleury, Chris Saski, Michael Atkins, Pieter deJong, Cheng-Cang Wu, Andreas Graner, Peter Langridge and Nils Stei

"A noisy situation": the Feminine and Feminist New Absurd in twenty-first-century British and American poetry and Send Shells

This thesis consists of a critical study, ‘“A Noisy Situation”: The Feminine and Feminist New Absurd in Twenty-first Century British and American Poetry’, followed by a poetry collection, $Send$ $Shells$. The critical study is a guidebook to the New Absurd, and thereby informs the reading of $Send$ $Shells$. Chapter One introduces the New Absurd as a descendant of male-dominated Absurdism; feminine and feminist humour is explored through Sam Riviere, Heather Phillipson, Selima Hill and Luke Kennard. Chapters Two, Three and Four focus on individual poets: Jennifer L. Knox’s $A$ $Gringo$ $Like$ $Me$, Emily Berry’s $Dear$ $Boy$ and Caroline Bird’s $The$ $Hat-Stand$ $Union$ and $In$ $These$ $Days$ $of$ $Prohibition$. The following themes are investigated: culture, class, and elitism; reality and imagination; feminine humour and sadness. Chapter Five explores apocalypse and technology through Maxine Chernoff, Jane Yeh, and Anne Carson. Chapter Six analyses failures to communicate through Rebecca Perry, Crispin Best, Rachael Allen, and Sara Woods. In conclusion Kayo Chingonyi, Rishi Dastidar, Mona Arshi and Anne Boyer are read to explore poets utilising the New Absurd, a prominent and influential movement in modern poetry, which does not have a specific membership, and might be seen as an aesthetic rather than a school
