Search for Lorentz invariance breaking with a likelihood fit of the PKS 2155-304 flare data taken on MJD 53944
(Elsevier, 2011)
Several models of Quantum Gravity predict Lorentz Symmetry breaking at energy scales approaching the Planck scale (∼1019 GeV). With present photon data from the observations of distant astrophysical sources, it is possible ...
Discovery and follow-up studies of the extended, off-plane, VHE gamma-ray source HESS J1507-622
(EDP Sciences, 2011)
Context. The detection of gamma-rays in the very-high-energy (VHE) range (100 GeV−100 TeV) offers the possibility of studying the parent population of ultrarelativistic particles found in astrophysical sources, so it is ...
Data transformations and goodness-of-fit tests for type-II right censored samples
(Springer, 2015)
We suggest several goodness-of-fit (GOF) methods which are appropriate
with Type-II right censored data. Our strategy is to transform the original observations
from a censored sample into an approximately i.i.d. sample ...
Denjoy-Wolff theorems for Hilbert’s and Thompson’s metric spaces
(Springer, 2018)
We study the dynamics of fixed point free mappings on the interior of a normal, closed cone in a Banach space that are nonexpansive with respect to Hilbert’s metric or Thompson’s metric. We establish several Denjoy-Wolff ...
Performance of various cyanide degrading bacteria on the biodegradation of free cyanide in water
(Elsevier, 2019)
This study reports on the biodegradation of free cyanide (FCN) by cyanide degrading bacteria (CDB) that were isolated from mining wastewater and thiocyanate containing wastewater. The performance of these isolates was ...
Multiple emergences of genetically diverse amphibian-infecting chytrids include a globalized hypervirulent recombinant lineage
(National Academy of Sciences, 2011)
Batrachochytrium dendrobatidis (Bd) is a globally ubiquitous fungal infection that has emerged to become a primary driver of amphibian biodiversity loss. Despite widespread effort to understand the emergence of this ...
Liturgical aspects of funeral services in reformed churches of African origin
(AOSIS, 2010)
How can the Reformed Churches of African origin arrive at a Biblical and contextual liturgy for their funeral services? Liturgy in death situations teaches people the meaning of death, and to the African, a proper funeral ...
Sensilla on antennae, ovipositor and tarsi of the larval parasitoids, Cotesia sesamiae (Cameron 1906) and Cotesia flavipes Cameron 1891 (Hymenoptera: Braconidae): a comparative scanning electron microscopy study
(Société Entomologique de France, 2011)
Two braconid parasitoids of cereal stemborers in eastern Africa, Cotesia sesamiae and Cotesia flavipes, have been shown to display a similar hierarchy of behavioural events during host recognition and acceptance. In order ...
Morphological reinforcement, ancient introgressive hybridization and species delimitation in African stem-borer species of the genus Sesamia Guenée (Lepidoptera: Noctuidae)
(Wiley-Blackwell, 2011)
Species delimitation, an issue central to systematics and biodiversity studies, is addressed in the epunctifera group of the stem borer genus Sesamia Guenée (Lepidoptera: Noctuidae). This group is composed of four sub-Saharan ...
Pricing of single stock futures and dividend risk
(Investement Analyst Society of South Africa, 2011)
In this paper we consider the fair pricing of single stock futures (SSFs) and the effect of dividend risk on the dividend compensation component in the pricing formulas. SSF valuation is subject to the pricing of discrete ...
