Coupling, reinforcement, and speciation
(University of Chicago Press, 2018)During the process of speciation, populations may diverge for traits and at their underlying loci that contribute barriers to gene flow. These barrier traits and barrier loci underlie individual barrier effects, by which ... -
Cell-autonomous role of GFRα1 in the development of olfactory bulb GABAergic interneurons
(The Company of Biologists, 2018-05-18)GFRα1, a receptor for glial cell line-derived neurotrophic factor (GDNF), is critical for the development of the main olfactory system. The olfactory bulb (OB) of Gfra1 knockout mice shows significant reductions in the ... -
Risky sexual behaviour and contraceptive use in contexts of displacement : insights from a cross-sectional survey of female adolescent refugees in Ghana
(BMC (part of Springer Nature), 2019-08-16)Background: Difficulty in accessing sexual and reproductive healthcare is one of the challenges young refugee women face worldwide, in addition to sexual exploitation, violence and abuse. Although Ghana hosts several ... -
Primary processing neuropils associated with the malleoli of camel spiders (Arachnida, Solifugae) : a re-evaluation of axonal pathways
(BMC (part of Springer Nature), 2019-08-02)Background - Arachnids possess highly specialized and unorthodox sense organs, such as the unique pectines of Scorpiones and the malleoli of Solifugae. While the external morphology, numbers, and shapes of sensory organs ... -
An integrated approach to processing WHO-2016 verbal autopsy data : the InterVA-5 model
(BMC (part of Springer Nature), 2019-05-30)Background: Verbal autopsy is an increasingly important methodology for assigning causes to otherwise uncertified deaths, which amount to around 50% of global mortality and cause much uncertainty for health planning. The ... -
Factors influencing the use of supervised delivery services in Garu-Tempane District, Ghana
(BMC (part of Springer Nature), 2019-04-27)Background: There is evidence that supervised delivery has the potential to improve birth outcomes for both women and newborns. However, not all women especially in low-income settings like Ghana use supervised delivery ... -
Associations between the severity of obstructive lower urinary tract symptoms and care-seeking behavior in rural Africa : a cross-sectional survey from Uganda
(Public Library of Science, 2017)Background: Global estimates indicate that by 2018 2.3 billion individuals worldwide will suffer from lower urinary tract symptoms (LUTS), with 1.1 billion having LUTS related to bladder outlet obstruction (BOO). Left ... -
Stochastic thermodynamics for Ising chain and symmetric exclusion process
(American Physical Society, 2017)We verify the finite-time fluctuation theorem for a linear Ising chain in contact with heat reservoirs at its ends.Analytic results are derived for a chain consisting of two spins. The system can be mapped onto a model ... -
Tracking the evolution of causal cognition in humans
(Istituto Italiano di Antropologia, 2017)We suggest a seven-grade model for the evolution of causal cognition as a framework that can be used to gauge variation in the complexity of causal reasoning from the panin-hominin split until the appearance of cognitively ... -
Effectiveness of home-based nutritional counselling and support on exclusive breastfeeding in urban poor settings in Nairobi : a cluster randomized controlled trial
(BMC (part of Springer Nature), 2017)Background: Exclusive breastfeeding (EBF) improves infant health and survival. We tested the effectiveness of a homebased intervention using Community Health Workers (CHWs) on EBF for six months in urban poor settings in ... -
Demonstration and pantomime in the evolution of teaching
(Frontiers Media, 2017)Donald proposes that early Homo evolved mimesis as a new form of cognition. This article investigates the mimesis hypothesis in relation to the evolution of teaching. The fundamental capacities that distinguish hominin ... -
Trade-offs in multi-purpose land use under land degradation
(MDPI, 2017)Abstract: Land provides a host of ecosystem services, of which the provisioning services are often considered paramount. As the demand for agricultural products multiplies, other ecosystem services are being degraded or ... -
Lateralization of the avian magnetic compass : analysis of its early plasticity
(MDPI, 2017)In European Robins, Erithacus rubecula, the magnetic compass is lateralized in favor of the right eye/left hemisphere of the brain. This lateralization develops during the first winter and initially shows a great plasticity. ... -
STIAS–Wallenberg Roundtable on mHealth : towards a roadmap for image-based mobile technologies for health care
(Academy of Science of South Africa, 2017)No abstract available -
General criterion for harmonicity
(American Physical Society, 2017)Inspired by Kubo-Anderson Markov processes, we introduce a new class of transfer matrices whose largest eigenvalue is determined by a simple explicit algebraic equation. Applications include the free energy calculation for ... -
Review and recommendations on management of adult female thalassemia patients with hypogonadism based on literature review and experience of ICET-A network specialists
(PAGEpress, 2017)Background: Multi-transfused thalassemia major (TM) patients frequently develop severe endocrine complications, mainly due to iron overload, anemia and chronic liver disease, which require prompt diagnosis, treatment and ... -
A smartphone-based consultation system for acute burns – methodological challenges related to follow-up of the system
(Taylor & Francis Open, 2017)Background: A smartphone-based consultation system for acute burns is currently being implemented in the Western Cape, South Africa. Even though studies indicate that similar systems for burns tend to support valid diagnosis ... -
Medical mobile technologies – what is needed for a sustainable and scalable implementation on a global scale?
(Taylor & Francis Open, 2017)Current advances within medical technology show great potential from a global health perspective. Inexpensive, effective solutions to common problems within diagnostics, medical procedures and access to medical information ... -
Image-based mHealth for remote diagnostic assistance a means to promote equity in quality care

Understanding and acting on the developmental origins of health and disease in Africa would improve health across generations
(Taylor & Francis Open, 2017)Data from many high- and low- or middle-income countries have linked exposures during key developmental periods (in particular pregnancy and infancy) to later health and disease. Africa faces substantial challenges with ...
