Extended TQFTs via generators and relations I: The extended toric code
(World Scientific Publishing, 2020)In his PhD thesis [G. Goosen, Oriented 123-tqfts via string-nets and state-sums, PhD thesis, Stellenbosch University, Stellenbosch (2018)], Goosen combined the string-net and the generators-and-relations formalisms for ... -
Extended VHE γ-ray emission towards SGR1806-20, LBV 1806-20, and stellar cluster Cl 1806-20
(EDP Sciences, 2018)Using the High Energy Spectroscopic System (H.E.S.S.) telescopes we have discovered a steady and extended very high-energy (VHE) γ-ray source towards the luminous blue variable candidate LBV 1806−20, massive stellar cluster ... -

Extending risk budgeting for market regimes and quantile factor models
(Infopro Digital Risk, 2018)We combine several disparate avenues in the literature to create a novel, unified risk- based optimization framework. Specifically, we extend an existing risk-budgeting approach to allow for changing market regimes and ... -
Extension of projection mappings
(Taylor & Francis, 2020)We provide sufficient conditions for a map between projection lattices of semi-finite von Neumann algebras to be extended to a Jordan *-homomorphism. These conditions are sufficiently general for the procedures developed herein ... -
Extensive broadband X-ray monitoring during the formation of a giant radio jet base in Cyg X-3 with AstroSat
(IOP Publishing, 2018)We present X-ray spectral and timing behavior of Cyg X-3 as observed by AstroSat during the onset of a giant radio flare on 2017 April 1–2. Within a timescale of a few hours, the source shows a transition from the hypersoft ... -
Extent and nature of motor difficulties based on age, ethnicity, gender and socio–economic status in a selected group of three–to five–year–old children
(Stellenbosch Univ, 2015)Attention to adequate motor development is important during the pre–school years, to minimise possible motor difficulties when the child grows older. The aim of this study was to establish the nature and extent of motor ... -
The extent and status of environmental management frameworks (EMFs) in South Africa, 2006-2015
(Taylor & Francis, 2017)An environmental management framework (EMF) is a uniquely South African environmental management tool legislated since 2006. Although the tool has been widely applied there has been no empirical research on the overall ... -
External contextual factors in information security behaviour
(SITEPRESS, 2020)Human behaviour is often considered to be irrational, difficult to understand, and challenging to manage. This phenomenon has a direct impact on the way in which humans behave when confronted with information security ... -
Extracellular matrix biomarker, fibulin-1, is closely related to NT-proBNP and soluble urokinase plasminogen activator receptor in patients with aortic valve stenosis (The SEAS study)
(2014-07-11)Background: Fibulin-1, a circulating extracellular matrix glycoprotein, has been associated with arterial disease and elevated N-terminal prohormone B-type natriuretic peptide (NT-proBNP) in diabetes. Soluble urokinase ... -
Extracellular matrix biomarker, Fibulin–1 and Its association with Soluble uPAR in a Bi-ethnic South African population: the SAfrEIC study
(Elsevier, 2015)Background Fibulin-1 and soluble urokinase-type plasminogen activator receptor (suPAR) emerged as mediators in the development of sclerotic disease. SuPAR along with C-reactive protein (CRP) and albumin delineate ... -
Extracting the February 1956 ground level enhancement event from legacy cosmic ray recordings
(Springer, 2018)Early continuous recordings of cosmic rays, as measured with Carnegie Type C Ionization Chambers, were made on rolls of photographic paper. This paper describes the extraction of the ionization data of the February 1956 ... -
Extracting the ground level enhancement event of February 1956 from Legacy cosmic ray recordings
(IEEE, 2018)Early continuous recordings of cosmic rays, as measured with Carnegie Type C Ionization Chambers, were made on rolls of photographic paper. This paper describes the extraction of the ionization data of a ground level ... -
Extraction of molasses from sugar crystals in a centrifuge
(Taylor & Francis, 2014)Massecuite is a mixture of sugar crystals and molasses produced during the manufacture of sugar. A centrifuge, which is a rotating cylindrical basket, is used to separate the sugar crystals from the molasses. Water and ... -
The extraction of the temperature gradient from measured temperature profiles with uncertainty propagation, as applied to the high temperature test unit
(SAAM, 2010)This paper highlights the usefulness of applying analytical methods for uncertainty analysis to a least-squares polynomial fit. It also presents an equation to calculate the confidence interval in the slope of a regression ... -
Extraction of uranium from synthetic nuclear conversion plant waste
(Taylor & Francis, 2019)The nuclear conversion plant operated at Necsa in the past resulted in the formation of a large amount of waste material containing ~ 50% U, which has reuse potential if the recovery thereof can be achieved. The waste ... -
The extraordinary outburst in the massive protostellar system NGC 6334I-MM1: flaring of the water masers in a north-south bipolar outflow driven by MM1B
(IOP Publishing, 2018)We compare multi-epoch sub-arcsecond Very Large Array imaging of the 22 GHz water masers toward the massive protocluster NGC 6334I observed before and after the recent outburst of MM1B in (sub)millimeter continuum. Since ... -
An extraordinary outburst in the massive protostellar system NGC 6334I-MM1: quadrupling of the millimeter continuum
(IOP, 2017)Based on sub-arcsecond Atacama Large Millimeter/submillimeter Array (ALMA) and Submillimeter Array (SMA) 1.3 mm continuum images of the massive protocluster NGC 6334I obtained in 2015 and 2008, we find that the dust emission ... -
Extremal function pairs in asymmetric normed linear spaces
(ELSEVIER, 2014)In [4] Kemajou et al. constructed the injective hull in the category of T₀-quasi-metric spaces with nonexpansive maps that they called q-hyperconvex hull. In this paper, we study properties of functions pairs of the ... -
Extremist ideology, political violence and women access to education in Africa: insights from North-East Nigeria
(IFE Centre for Psychological Studies (ICPS), 2017)The outbreak of violence has always generates untoward consequences for the education sector, impacting negatively on safety of learning environment, security of teachers and students alike. Underscoring the linkage between ...
