Geophysical and ecological dynamics within lakes of the McMurdo Dry Valleys, Antarctica, are controlled by the presence of permanent ice covers. Despite the importance of the permanent ice cover, there have been no studies that have examined specific couplings between changes in the geophysical properties of the ice covers and dynamic ecological processes within the underlying water column. Her...

Stationary iterative methods for solving systems of linear equations are considered by some as out of date and out of favor, as compared to methods based on Krylov subspace iterations. However, these methods are still useful in many circumstances because they are easier to implement and, more importantly, can be used as pre-conditioners in combination with Krylov-subspace methods. In this note,...

Abstract. Objective: In this pilot study, the authors examined the effectiveness of a 4-week resilience intervention to enhance resilience, coping strategies, and protective factors, as well as decrease symptomatology during a period of increased academic stress. Participants and Methods: College students were randomly assigned to experimental (n = 30) and wait-list control (n = 27) groups. The...

The phantom midge, Chaoborus, is a dipteran, the larvae of which occur in many freshwater habitats and are known to be vulnerable to predation by fish. The hypothesis was tested that ovipositing imagines of Chaoborus use chemical cues to detect predatory fish and avoid depositing eggs into waterbodies containing fish kairomones. The experimental setup consisted of cages with two small water-fil...

MOTIVATION 454 pyrosequencing, by Roche Diagnostics, has emerged as an alternative to Sanger sequencing when it comes to read lengths, performance and cost, but shows higher per-base error rates. Although there are several tools available for noise removal, targeting different application fields, data interpretation would benefit from a better understanding of the different error types. RESUL...

MOTIVATION Throughout the recent years, 454 pyrosequencing has emerged as an efficient alternative to traditional Sanger sequencing and is widely used in both de novo whole-genome sequencing and metagenomics. Especially the latter application is extremely sensitive to sequencing errors and artificially duplicated reads. Both are common in 454 pyrosequencing and can create a strong bias in the e...

This article documents the public availability of (i) transcriptome sequence data, assembled and annotated contigs and unigenes, and BLAST hits from the Queensland fruit fly, Bactrocera tryoni; (ii) 75 single-nucleotide variants (SNVs) from 454 sequencing of reduced representation libraries for Phalangiidae harvestmen, Megabunus armatus, Megabunus vignai, Megabunus lesserti, and Rilaena triangu...

The Minimum Error Correction (MEC) approach is used as a metric for reconstruction of haplotypes from NGS reads. In this paper, we show that the MEC may encounter with imprecise reconstructed haplotypes for some NGS devices. Specifically, using mathematical derivations, we evaluate this approach for the SOLiD, Illumina, 454, Ion, Pacific BioSciences, Oxford Nanopore, and 10X Genomics devices. O...
