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.”

She fought against illness, had to get the green light from medical personnel shortly before her main race, and was very nervous. However, on 5 June 2017, the blind athlete Louzanne Coetzee managed to improve the T11 5 000 m world record with more than 20 seconds.

The Kovsie star’s time of 18:14.27 at the ParAthletics Grand Prix in Nottwil, Switzerland, was approximately 23 seconds faster than her previous world record (18:37.23). In addition, Coetzee, who works at the Institute for Reconciliation and Social Justice at the University of the Free State, also improved the South African T11 800 m record to 2:30.18 on 2 June 2017, and her 4:59.54 on 3 June 2017 in the T11 1 500 m was almost another national record.

Carried by UFS and other support
“One could never be ungrateful when running close to your personal best,” Coetzee said. “Fortunately, with God’s blessing, the support of everybody at home, support from the university, as well as my mom and them, it really was a very blessed and successful event.”

According to her coach, Rufus Botha, Coetzee was not feeling well before the event and had to get medical clearance before the 5 000 m. He told her not to run too hard, even though their goal was 18:20. “She ran an incredible final 600 m, which brought the time down to 18:14,” he said. “It was amazing to watch.”

Botha’s knowledge valuable abroad
He enjoyed going overseas with Coetzee and her guide, Khothatso Mokone, for the first time. “His (Botha’s) experience, knowledge, support, and coaching was extremely valuable,” Coetzee said. “It will definitely help me in future: how to approach things, and everything he shared with us.”
