(Springer, 2024-05)INTRODUCTION : The anterior nasal spine is a pointed, midline projection of the maxilla. This bony structure dictates the overlying soft tissues providing the phenotypic features of the nose and upper lip and determines ...
-
(Elsevier, 2024-01)OBJECTIVES : Determine and compare the epidemiology, clinical characteristics, and injury severity among race entrants training towards different ultra-trail race distances. DESIGN : Retrospective cross-sectional ...
-
(MDPI, 2022-12-09)Maternal HIV exposure and intrauterine growth restriction (IUGR) due to placental insufficiency both carry major risks to early child growth. We compared the growth outcomes of children aged 18 months who had abnormal ...
-
(MDPI, 2023-09)BACKGROUND : Trail running is characterised by large elevation gains/losses and varying uneven running surfaces. Limited literature is available to help guide injury prevention strategies among trail runners. The purpose ...
-
(South African Water Research Commission, 2023-02)As part of the Eskom rebate programme, energy-efficient hot water systems such as solar water heaters (low pressure), heat pumps and energy-efficient showerheads were rolled out to the public as a measure to conserve and ...
-
(JMIR Publications Inc., 2023)BACKGROUND : The COVID-19 pandemic undermined gains in reducing maternal and perinatal mortality in South Africa. The Mphatlalatsane Initiative is a health system intervention to reduce mortality and morbidity in women and ...

(MDPI, 2022-05-25)Evidence-based knowledge of the relationship between foods and nutrients is needed to inform dietary-based guidelines and policy. Proper and tailored statistical methods to analyse food composition databases (FCDBs) could ...
-
(Taylor and Francis, 2024)In medical diagnostic research, it is customary to collect multiple continuous biomarker measures to improve the accuracy of diagnostic tests. A prevalent practice is to combine the measurements of these biomarkers into ...
-
(Publisher UFLA, 2023-06)Movement of animals is often characterised by direction (measured on the circle) and distance (measured on the real line); but traditionally employed models often do not account for potential asymmetric directional movement, ...
-
(MDPI, 2022-07-06)Bimodal distributions have rarely been studied although they appear frequently in datasets. We develop a novel bimodal distribution based on the triangular distribution and then expand it to the multivariate case using ...
-
(MDPI, 2022-11-12)This article studies the estimation of the precision matrix of a high-dimensional Gaussian network. We investigate the graphical selector operator with shrinkage, GSOS for short, to maximize a penalized likelihood function ...
-
(MDPI, 2022-11-01)Classification using linear discriminant analysis (LDA) is challenging when the number of variables is large relative to the number of observations. Algorithms such as LDA require the computation of the feature vector’s ...
-
(MDPI, 2022-11)Analysing autoregressive counts over time remains a relevant and evolving matter of interest, where oftentimes the assumption of normality is made for the error terms. In the case when data are discrete, the Poisson model ...
-
(Springer, 2022-11)INTRODUCTION : Consumption of unhealthy foods in children contributes to high levels of childhood obesity globally. In developing countries there is paucity of empirical studies on the association. This study employed ...
