Big data- and artificial intelligence-based hot-spot analysis of COVID-19: Gauteng, South Africa, as a case study Open
The coronavirus disease 2019 (COVID-19) has developed into a pandemic. Data-driven techniques can be used to inform and guide public health decision- and policy-makers. In generalizing the spread of a virus over a large area, such as a pro…

Machine learning approach for the search of resonances with topological features at the Large Hadron Collider Open
The observation of resonances is unequivocal evidence of new physics beyond the Standard Model at the Large Hadron Collider (LHC). So far, inclusive and model-dependent searches have not provided evidence of new resonances, indicating thes…

An investigation of over-training within semi-supervised machine learning models in the search for heavy resonances at the LHC Open
In particle physics, semi-supervised machine learning is an attractive option to reduce model dependencies searches beyond the Standard Model. When utilizing semi-supervised techniques in training machine learning models in the search for …

Evaluating temperature and humidity gradients of COVID-19 infection rates in light of Non-Pharmaceutical Interventions Open
We evaluate potential temperature and humidity impact on the infection rate of COVID-19 with a data up to June 10 th 2020, which comprises a large geographical footprint. It is critical to analyse data from different countries or regions a…

Risk Adjusted Non-Pharmaceutical Interventions for the Management of COVID-19 in South Africa Open
A global analysis of the impact of non-pharmaceutical interventions (NPIs) on the dynamics of the spread of the COVID-19 indicates that these can be classified using the stringency index proposed by the Oxford COVID-19 Government Response …

Worldwide Effectiveness of Various Non-Pharmaceutical Intervention Control Strategies on the Global COVID-19 Pandemic: A Linearised Control Model Open
Background COVID-19 is a virus which has lead to a global pandemic. Worldwide, more than 130 countries have imposed severe restrictions, which form part of a set of non-pharmaceutical interventions (NPI)s. We aimed to quantify the country-…
