UFS researcher publishes the highest-cited Maths paper in the world in 2017
An article by Prof Abdon Atangana from the University of the Free State’s Institute for Groundwater Studies received New Hot Paper status from Clarivate Analytics.
An article on Applied Mathematics, published by Prof Abdon Atangana from the University of the Free State’s Institute for Groundwater Studies in 2017, was recently named New Hot Paper by Clarivate Analytics.

Hot paper status
Essential Science Indicators (ESI) is a unique and comprehensive compilation of science performance statistics and science trends. Data is based on journal article publication counts and citation data from Clarivate Analytics that enables researchers to conduct ongoing, quantitative analyses of research performance and track trends in science. Covering a multidisciplinary selection of 1 2000+ journals from around the world, this in-depth analytical tool offers data for ranking papers, scientists, institutions, countries, and journals. 

ESI from Clarivate Analytics is updated every two months. The New Hot Papers, which are papers published in the past two years, are in the top one-tenth of one percent (0.1%) for their field and publication period. Prof Atangana’s paper had the highest cite count in the field of Mathematics. 

His article that received the New Hot Paper status is titled: “The new fractional derivative and application to nonlinear Fisher’s reaction-diffusion equation”.

The concept of fractional differential operators with non-singular kernel has captured the minds of several researchers in the past year due to their wider applicability in almost all fields of science, engineering and technology. The new fractional differential operators have opened new windows to model complex real-world problems that could not be modelled using the Newtonian and the well-known Riemann-Liouville fractional differential operators. 

“These operators are the way forward in modelling real-world problems in all disciplines, as they are able to include into mathematical formulation the effect of memory,” Prof Atangana said.

The Atangana-Baleanu fractional derivative
The professor developed a new fractional differential operator, called the Atangana-Baleanu fractional derivative. This derivative is able to describe real-world problems with different scales or problems that change their properties during time and space, for instance, the spread of cancer; the flow of water within heterogeneous aquifers, movement of pollution within fractured aquifers and many others.”

UFS provides sign language skills to locals

The public and private sectors are becoming more aware of the need for effective communication between employers, employees, and clients who use Sign Language. Given that Sign Language is the first language of approximately 600 000 people in South Africa, competence in the language means taking the first step towards more inclusive service delivery.
 
Shout Out Loud - a project that promotes Sign Language - has signed up Bloemfontein Celtics, Centlec, Beyond Boundaries, and the Mangaung Municipality on a Basic South African Sign Language course at the University of the Free State.
 
No miscommunication
 
Susan Lombaard, the Acting Head at the Department of South African Sign Language, was one of the lecturers who presented the 40-hour accredited course every Friday from 15 January-12 February 2016. Other lecturers who were responsible for training were Emily Matabane and Tshisikhawe Dzhivani.
 
Lombaard believes that learning Sign Language bridges the gap between the hearing and those who have impairments. “The benefit is that there will be no miscommunication. It happens that a deaf person walks into a bank or municipality offices and there is no communication. They need to write which is humiliating for that person.”
 
Towards a promising future
 
According to Goodwill Mokoena, Project Manager at Beyond Boundaries, the project will continue annually, and a larger intake of government departments and non-governmental organisations is expected in 2016.He also indicated that Shout Out Loud has achieved substantial success in its involvement with the Bartimea School for the Blind and Deaf.

Shout Out Loud selects one pupil every month, and flies them to Johannesburg to interpret on Bloemfontein Celtics’ magazine show. It is the only magazine show in South Africa that has a sign language interpreter. “The school has been achieving 100% in matric results because the pupils are selected on merit. This has enhanced their academic performance in such a marvelous way,” said Mokoena.
