Efficacy of novel small-quantity lipid-based nutrient supplements in improving long-chain polyunsaturated fatty acid status of South African infants: a randomised controlled trial
(Springer, 2020)
Background/objectives
The objective of this study was to investigate the efficacy of small-quantity lipid-based nutrient supplements (SQ-LNS) containing essential fatty acids (EFAs) with or without long-chain polyunsaturated ...
The impact of herbivore exclusion on forb diversity: comparing species and functional responses during a drought
(Wiley, 2020)
Rainfall and herbivory shape savannah herbaceous communities, but these disturbances are being altered globally. To assess potential consequences of such alterations, we evaluated herbivore effects on species and functional ...
Preparing recreation professionals: graduate attributes expected of entry-level recreation professionals in a South African context
(Taylor & Francis, 2020)
The unemployment rate of graduate students in South Africa (SA) has increased more than 4% in the past 10 years. This increase can be ascribed to the current economic situation as well as the unemployability of these ...
The monoamine oxidase inhibition properties of C6- and N1-substituted 3-methyl-3,4-dihydroquinazolin-2(1H)-one derivatives
(Springer, 2020)
Quinazolinone compounds are of interest in medicinal chemistry since they display a wide range of biological properties. In the present study, a series of C6- and N1-substituted 3-methyl-3,4-dihydroquinazolin-2(1H)-one ...
Prediction of 24-hour sodium excretion from spot urine samples in South African adults: a comparison of four equations
(Nature, 2020)
Repeated 24-hour urine collection is considered to be the gold standard for assessing salt intake. This is often impractical in large-population studies, especially in low–middle-income countries. Equations to estimate ...
Determining sample size adequacy for animal model studies in nutrition research: limits and ethical challenges of ordinary power calculation procedures
(Taylor & Francis, 2020)
Animal models are widely used in the field of nutrition research. Scientifically and ethically sound experiments need an adequate number of experimental units. The use of 5-10 units is common, but such sample sizes can be ...
Molecular imaging of a zirconium-89 labeled antibody targeting Plasmodium falciparum–infected human erythrocytes
(Springer, 2020)
Purpose
Nuclear imaging is an important preclinical research tool to study infectious diseases in vivo and could be extended to investigate complex aspects of malaria infections. As such, we report for the first time ...
Stride and translation invariance in CNNs
(Southern African Conference for Artificial Intelligence Research, 2020)
Convolutional Neural Networks have become the standard for image classification tasks, however, these architectures are not invariant to translations of the input image. This lack of invariance is attributed to the use of ...
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 ...
Tracking translation invariance in CNNs
(Southern African Conference for Artificial Intelligence Research, 2020)
Although Convolutional Neural Networks (CNNs) are widely used, their translation invariance (ability to deal with translated inputs) is still subject to some controversy. We explore this question using translation-sensitivity ...
