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.”

In view of the environmental and social problems faced in South Africa today, researchers such as Dr Inge Konik are hard at work mapping these issues and seeking long-term solutions. Dr Konik,  a lecturer in the Department of Journalism, Media and Philosophy at the Nelson Mandela Metropolitan University (NMMU) shared her views in a presentation on 6 May 2016. She spoke about revaluing indigenous ways of life and subsistence-focused lifeways, linking this to materialist ecological feminism, or ecofeminism for short.

Dr. Konik’s presentation, hosted by the Department of Philosophy at the Bloemfontein Campus of the University of the Free State (UFS), was entitled: “Transversal reflections on ecological feminism and ubuntu.” The research underpinning the presentation derived from Dr Konik’s doctoral thesis which was supervised by Ariel Salleh (University of Sydney) and Andrea Hurst (NMMU).

Dr Konik’s research suggests that ecofeminism - which is a convergence between environmentalism and feminism - may hold the answers to the question of how we may work against environmental and social injustices. She also proposed that society look back toward subsistence communities of the past, and those currently being marginalized in our industrial societies, and linked the values evidenced in the practices of these communities to the African philosophty of ubuntu. In order to solve  complex contemporary challenges Dr Konik suggests that we combine these seemingly disparate theoretical frames - ubuntu and ecofeminism - by applying a transversal approach, which involves openness to dialogue  between traditions.

“My focus was on ecological feminism and critical theory and very specifically on South Africa, given the challeges South Africa faces - the environmental and social challenges and what kind of frameworks would be helpful,” said Dr Konik, who will officially become a postdoctoral research fellow at the department as of July 2016.

Prof Pieter Duvenage, Head of the Departement, stated that compelling research outputs are anticipated from Dr Konik as a fellow.
