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.”

Prof Van den Oever gives students a different perspective

Prof Annie van den Oever from the Netherlands presented a series of guest lectures on media technologies to students of the Film and Visual Media Programme at the University of the Free State (UFS).

She played a part in conceptualising the Film and Visual Media Programme at the University of the Free State (UFS), and sees film from a perspective different from most young South Africans.

According to Chris Vorster, lecturer of the UFS BA Honours degree in Film and Visual Media, this is one of the reasons why Prof Annie van den Oever’s visit is of such great value. The actor, who is a lecturer in Drama and Theatre Arts, believes it is important to expose his students to influences outside their normal experience.

Prof Van den Oever, an extraordinary professor at the UFS since 2011, presented a series of guest lectures on media technologies from 11-14 April 2016 at the Audio Visual Studio on the Bloemfontein Campus. She is a senior researcher for Film at the University of Groningen in the Netherlands, and an Associated Researcher for Film at Paris 1, Panthéon Sorbonne, in France.

Another milieu

“It is invaluable for students, in any field of study, to receive as many influences from the outside. Therefore, it is important to have someone here from another milieu and context. And academically, she is outstanding,” says Vorster.

Vorster’s students are also exposed to practical expertise from the industry in the country, not only academics.

Relationship with UFS

Prof Van den Oever says she usually visits the UFS twice a year. Her recent lecture series on media technologies was about the power of visual and film culture today, and how you can understand its powers. “Why strange effects work strongly and why the strange is inserted, because people respond strongly to them,” she says.

Prof van den Oever enjoys meeting new people, and often works with colleagues from the UFS on various projects. She also is full of praise for the management of the university. “It is great to work across cultures, and be part of a university in transition.”
