A search for p-mode pulsations in white dwarf stars using the Berkeley Visible Imaging Tube detector
(Oxford University Press, 2014)
We present high-speed photometry (resolution 0.1 s) obtained during the commissioning of the
Berkely Visible Imaging Tube system on the Southern African Large Telescope (SALT). The
observations were an attempt to search ...
The analysis of indexed astronomical time series – XII. The statistics of oversampled Fourier spectra of noise plus a single sinusoid
(Oxford University Press, 2015)
With few exceptions, theoretical studies of periodogram properties focus on pure noise time
series. This paper considers the case in which the time series consists of noise together with a
single sinusoid, observed at ...
Legume phylogeny and classification in the 21st century: Progress, prospects and lessons for other species-rich clades
(Botanischer Garten und Botanisches Museum, 2013)
The Leguminosae, the third-largest angiosperm family, has a global distribution and high ecological and economic importance. We examine how the legume systematic research community might join forces to produce a comprehensive ...
Reconstructing the deep-branching relationships of the papilionoid legumes
(Elsevier, 2013)
Resolving the phylogenetic relationships of the deep nodes of papilionoid legumes (Papilionoideae) is essential to understanding the evolutionary history and diversification of this economically and ecologically important ...
Genome-wide SNP identification by high-throughput sequencing and selective mapping allows sequence assembly positioning using a framework genetic linkage map
(BioMed Central, 2010)
Determining the position and order of contigs and scaffolds from a genome assembly within an organism’s genome remains a technical challenge in a majority of sequencing projects. In order to exploit contemporary technologies ...
Population ecology of Psammobates oculifer in a semi-arid environment
(Taylor & Francis and UNISA Press, 2013)
We studied the ecology of Psammobates oculifer over 13 months near Kimberley, South Africa, to ascertain if the population’s life history traits conform to chelonian patterns in arid environments. Capture rates were highest ...
Towards ensuring scalability, interoperability and efficient access control in a multi-domain grid-based environment
(South African Institute of Electrical Engineers, 2013)
The application of grid computing has been hampered by three basic challenges:
scalability, interoperability and efficient access control which need to be optimized before a full-scale
adoption of grid computing can take ...
Gonad differentiation in zebrafish is regulated by the canonical Wnt signalling pathway
(Society for the Study of Reproduction, 2014)
Zebrafish males undergo a ‘‘juvenile ovary-to-testis’’ gonadal transformation process. Several genes, including nuclear receptor subfamily 5, group A (nr5a) and anti-Mu¨ llerian hormone (amh), and pathways such as Tp53-mediated ...
Evolutionary history of the Corallinales (Corallinophycidae, Rhodophyta) inferred from nuclear, plastidial and mitochondrial genomes
(Elsevier, 2011)
Systematics of the red algal order Corallinales has a long and convoluted history. In the present study, molecular approaches were used to assess the phylogenetic relationships based on the analyses of two datasets: a large ...
DAMPD: a manually curated antimicrobial peptide database
(Oxford University Press, 2012)
The demand for antimicrobial peptides (AMPs) is rising because of the increased occurrence of pathogens that are tolerant or resistant to conventional antibiotics. Since naturally occurring AMPs could serve as templates ...
