A CMIP5 Model Selection Specific to South Africa's Winter Rainfall Zone
Published 2023“…While the range of future temperature projections of the final ensemble are somewhat constrained in comparison to the full ensemble, the primary utility is argued to be the reduced number of models where a future researcher may consider each model's projected future climate pathway individually before selecting a model, or models, which best informs their use case, whilst being assured that this model performs suitably well in the region and that the initial ensemble considered adequately represents model uncertainty, while strong similarity between two or more models within the ensemble will not be unduly biasing results.…”

A patient-specific adaptation of the Living Human Heart Model in application to pulmonary hypertension
Published 2020“…We, therefore, present a solution to modify the Living Human Heart Model (LHHM) to obtain a patient-specific geometry using the thermal expansion method, with iteratively adjusted parameters that accurately simulate the case of a 72-year-old female patient suffering from secondary pulmonary hypertension caused by mitral valve regurgitation (MR). …”

The role of Cysteinyl leukotriene receptor-1 during experimental helminth infections in murine model
Published 2021“…Furthermore, recall of memory responses to N. brasiliensis was abrogated in cysLTR1 -/- mice, with higher numbers of adult worms recovered at day 5 post re-infection in cysLTR1-/- mice comparison with wild type mice. Additionally, cysLTR1-/- mice exhibited impaired production of IL-13 in the lungs and draining lymph nodes compared with wildtype mice. …”

Enhancement of digital elevation models using tree-based ensemble machine learning algorithms
Published 2024“…Thus, global digital elevation models (DEMs) have gained worldwide prominence due to their free availability; a prime advantage when compared to prohibitively expensive airborne topographic surveys. …”

A methodology for integrated thermofluid modelling of radiant superheaters in steady state and transient operations
Published 2019“…Due to the challenges associated with obtaining comprehensive real plant data in an industrial setting, a validation methodology was proposed that is based on a combination of plant design C-schedules and a boiler mass and energy balance, as well as limited plant measurements. The consistent comparisons with C-schedule data provide evidence of the validity of the model, which was further demonstrated via the comparisons with real plant data. …”

Developing dynamic energy budget (DEB) models for small pelagic fishes in the Southern Benguela
Published 2022“…Thus, increased growth rates from good food availability outweighed decreased growth rates from cool temperatures and resulted in higher egg batch production in adults. Comparisons of Southern Benguela anchovy and sardine to similar species in other ecosystems showed differences in core parameters between regions because of the influence of environmental inputs and species differences, indicating that model parameters may not be species-specific or transferable between ecosystems. …”
