This paper presents radiation efficiency and gain bounds for microstrip patch antennas. The presented bounds are shown to be good predictors of antenna performance. Using the bounds, patch miniaturization techniques based on high permittivity substra

Abstract Covid-19 posed little danger to children. Nevertheless, the South African government imposed lockdown measures that impeded children’s education, play and food. Schools were closed, feeding schemes were halted and organised sports were ban

Abstract The critical role of specifying micro‐Doppler mode performance in the modelling and development of modern radar systems is investigated. The authors focus on the detection of micro‐Doppler modulation from light aircraft, analysing data f

Background: Breastfeeding is widely acknowledged as the optimal method of infant feeding. However, the percentage of South African mothers who exclusively breastfeed remains alarmingly low. Healthcare workers (HCWs) are pivotal in promoting breastfee

Solar radio emissions provide several unique diagnostics to estimate different physical parameters of the solar corona, which are otherwise simply inaccessible. However, imaging the highly dynamic solar coronal emissions spanning a large range of ang

Abstract Background Key populations (KP), including men who have sex with men (MSM), female sex workers (FSW), and transgender women (TGW), experience a disproportionate burden of HIV, even in generalized epidemics like South Africa. Given this dispr

Abstract Previous studies showed that accelerated enhanced recovery programs (ERPs) with discharge 1–3 days after colorectal surgery are feasible for specific patients without compromising patients’ safety. This study aimed to examine the inciden

Background Globally, there is suboptimal coverage of antiretroviral treatment to treat and prevent HIV. It is crucial for individuals to know their partner’s HIV status so they may use all appropriate and available prevention tools. For sexual mino

Studying insect fossils, particularly those preserved as compressions in sedimentary matrices, can be difficult due to the taphonomic processes that often result to poor preservation and contrast of structures compared to the embedding matrix. To add

Although HIV infection can be managed with antiretroviral drugs, there is no cure and therapy has to be taken for life. Recent successes in animal models with HIV-specific broadly neutralising antibodies (bNAbs) have led to long-term virological remi
