Extremely broad lyαline emission from the molecular intragroup medium in Stephan’s quintet: evidence for a turbulent cascade in a highly clumpy multiphase medium?
(IOP Publishing, 2022)
We present Hubble Space Telescope Cosmic Origin Spectrograph (COS) UV line spectroscopy and integral-field
unit (IFU) observations of the intragroup medium in Stephan’s Quintet (SQ). SQ hosts a 30 kpc long shocked ...
Considerations for optimizing the photometric classification of supernovae from the Rubin observatory
(IOP Publishing, 2022)
The Vera C. Rubin Observatory will increase the number of observed supernovae (SNe) by an order of
magnitude; however, it is impossible to spectroscopically confirm the class for all SNe discovered. Thus,
photometric ...
Role of cytocentrifugation combined with nuclear fast picroindigocarmine staining in detecting cryptozoospermia in men diagnosed with azoospermia
(Seoul: Korean Society for Sexual Medicine and Andrology, 2022)
Azoospermia is defined as the absence of spermatozoa in the pellet of a centrifuged semen sample. In fact, when a
basic semen analysis fails to detect sperm in the ejaculate, there is still the possibility of detecting ...
Covid-19 prevalence among healthcare workers. A systematic review and meta-analysis
(MPDI, 2022)
Understanding the burden of SARS-CoV-2 infections among healthcare workers is a critical
component to inform occupational health policy and strategy. We conducted a systematic review and
meta-analysis to map and analayse ...
A review of the fractal market hypothesis for trading and market price prediction
(MPDI, 2022)
This paper provides a review of the Fractal Market Hypothesis (FMH) focusing on financial
times series analysis. In order to put the FMH into a broader perspective, the Random Walk and Efficient Market Hypotheses are ...

(BMJ Publishing Group, 2022)
Over the last 30 years, South Africa
has experienced four ’colliding epidemics’ of HIV and
tuberculosis, chronic illness and mental health, injury and
violence, and maternal, neonatal, and child mortality,
which have ...
Cosmos2020: A panchromatic view of the universe to z∼10 from two complementary catalogs
(IOP Publishing, 2022)
The Cosmic Evolution Survey (COSMOS) has become a cornerstone of extragalactic astronomy. Since the last public
catalog in 2015, a wealth of new imaging and spectroscopic data have been collected in the COSMOS field. This ...
Validation of the hera phase i epoch of reionization 21 cm power spectrum software pipeline
(IOP Publishing, 2022)
We describe the validation of the HERA Phase I software pipeline by a series of modular tests, building up to an
end-to-end simulation. The philosophy of this approach is to validate the software and algorithms used in ...
Mapping rangeland ecosystems vulnerability to lantana camara invasion in semi-arid savannahs in South Africa
(African journal of ecology Wiley, 2022)
We mapped and modelled the potential areas vulnerable to Lantana camara (L. camara)
invasion in semi-arid savannah ecosystems in the communal lands of Bushbuckridge
and Kruger National Park, South Africa. Specifically, ...
