Introducing a novel silicon-on-insulator optical metamaterial waveguide that is compatible with CMOS technology

An optical waveguide is defined as a structure that can confine and guide optical light to follow a predefined path from a transmitter to a receiver. The waveguide that we are discussing is made of silicon semiconductor material that is built over a bulk insulating substrate made of silicon dioxide material. This silicon-on-insulator structure is fabricated with a well-known, simple, […]

Using superhydrophobic surfaces to reduce marine corrosion

The use of superhydrophobic structures in coalescence-induced droplet jumping and its application to materials in marine atmosphere corrosion

Marine atmospheric corrosion – the effect of seawater and sea air in coastal areas – is costly to our societies in terms of safety, economics, functionality, and cultural heritage. To deal with marine atmospheric corrosion, the current general protection measures mainly aim to improve the corrosion resistance of the material itself, or to isolate the base from the corrosive medium, […]

Epidemiology of idiopathic inflammatory myopathies in Africa: A contemporary systematic review

Written by

Method We registered the protocol with PROSPERO, CRD42020186781. PRISMA guidelines were applied to report this review. Studies addressing the epidemiology of IIMs in Africa and released before 30 December 2020, were searched for in electronic databases (MEDLINE, EMBASE and African Journals Online) and manually. Case series involving fewer than 9 participants, studies focusing on IIMs in pregnant women, articles lacking […]

Epidemiology of digital clubbing and hypertrophic osteoarthropathy: A systematic review

Written by

In reporting this systematic review, we were guided by PRISMA statements. Studies reporting the prevalence of HOA/clubbing that had been released up to 23 March 2021, were searched for in electronic databases (PubMed, EMBASE, Web of Sciences) and manually. Studies not involving humans, those with fewer than 10 participants, those whose full-texts were not available after a request to the […]

Epidemiology of Sjogren syndrome in Africa: A scoping review

Background Children are susceptible to injuries and wounds that require medical attention. Despite being treated in a controlled hospital setting, wounds are at risk of infections. Therefore, there is an urgent need to improve wound healing protocols that prevent infections and avoid unnecessary use of antibiotics. Honey is a natural substance that has been used for wound healing since ancient […]

Understanding ethics in society via artificial intelligence and game theory

Written by

The importance of ethical conduct has been long known, and continues to be a pressing concern not only for society in general, but also in business, and in the applications of artificial intelligence (AI). However, while AI is among the foremost of contemporary fields where ethics is a concern, AI has not itself previously served the purpose of clarifying the […]

Molecular and structural changes characterizing salinity tolerance in Aedes aegypti mosquito: The major global vector of arboviral diseases

Written by

Introduction From an origin in tropical forests where it blood fed on animals, Aedes aegypti adopted a preference for developing near human habitations and blood feeding on humans, spreading widely to become the principal vector of important arboviral diseases including dengue, chikungunya, yellow fever, and Zika (Ramasamy, et al., 2021). It was regarded as an obligate fresh water (FW) […]
