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.”

John Reid Coulter is one South Africa’s leading exponents of historical performance practice. He completed his studies in harpsichord with Jacques Ogg at the Royal Conservatory in The Hague. He has taught at the universities of Potchefstroom, Witwatersrand and Pretoria. John has an avid interest in the building of early keyboard instruments and has built a number of harpsichords and a fortepiano. He has performed as soloist and continuo player in The Netherlands, Norway and Germany. His baroque ensemble ‘Banda di Giovanni’ has premiered a number of works in South Africa, the most recent being the cantata ‘Apollo e Dafne’ by G.F. Handel in 2004 and the Serenata à tre ‘Mio cor, povero cor’ by Antonio Vivaldi in May 2007. John is also well known as an adjudicator at music festivals and as a composer has won numerous awards.

Deirdré Blignaut obtained a BA (Languages) degree from the University of the North West in 1988. She graduated cum laude and was awarded Best Student, Faculty of Arts. She began her career as translator at Transnet and later joined the Department of Arts and Culture as terminologist. In 1995 music become her full-time career and field of study. She studied singing with Prof Werner Nel until 2000 and repertoire with the late Anna Bender currently she studies with Eugenie Chopin. In 2002 she obtained a Performer’s Licentiate cum laude and was invited to participate in the Unisa International Bursary Competition. Deirdre is currently she is working towards a MMus (Performing Arts) through the University of Pretoria. She teaches voice at Pro Arte Alphen Park, lectures Methodology of Singing at the University of Pretoria and was recently appointed voice lecturer at the School of Music, North West University.

The fortepiano used in the concert was built by John Reid Coulter in 1986 and is a copy of a Stein fortepiano ca. 1780.
