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.”

The actor and film maker, Hannes van Wyk, known for his role as Krynauw du Boisson in the M-Net soapie Egoli, was named Kovsie Alumnus of the Year during the Kovsie Alumni Awards. He and six other former Kovsie students and staff were honoured at this gala event for their outstanding achievements and contributions to the UFS during 2012.

Van Wyk, who completed his BAEd in 1990 at the University of the Free State, was honoured for his contribution to, and development of the South African Film and Television industry. This includes his work as producer, writer, researcher and director of companies such as PACOFS, M-Net and the SABC.

The actor wasn’t the only person in the public eye to be celebrated at the event.

The well-known columnist, Hanlie Retief, who interviews the top newsmakers of the country every week for Rapport, was recognised with a Cum Laude Award. She was honoured in this category together with Paul Colditz, Chief Executive Officer of FEDSAS, the national representative organisation of governing bodies, and Judge Violet Phatshoane, founder of Phatshoane & Henney Attorneys and judge in the High Court of South Africa.

Hanlie told the audience that her degree from Kovsies opened doors for her. She spoke about the interview she had in those days with the athlete Zola Budd, her first story to be published in the university publication, Bult.

Prof Johan Willemse, who is internationally known as an agricultural economist, and Dr Philemon Akach, known for his contribution to the development of Sign Language on the continent, were bestowed with the Alumni Award for outstanding service to the UFS.

The Kovsie Ambassador Award was presented to Judge Faan Hancke, Extraordinary Professor in the Faculty of Law at the UFS. As a former Kovsie, he served more than 12 years as Council member during his career and is still involved with the Alumni Trust.
