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.”

Human Rights Desk takes up anti-xenophobia initiative
2015-05-06

In light of the recent violent attacks on foreigners in South Africa, the University of the Free State’s (UFS) Human Rights Desk hosted a symposium on the issue of xenophobia on Wednesday 29 April 2015 on the Bloemfontein Campus. In collaboration with volunteers from the Institute of Reconciliation and Social Justice (IRSJ), students had the opportunity to discuss the underlying issues of the problem.

Joe Besigye, Numpumelelo Ngcobo, Phiwe Mathe, and Dr Christian Williams lead the symposium. The panel aimed at providing guidance, answers, and explanations to the different narratives offered in the wake of the conflict. The underlying reasons for the conflict were investigated, which included socio-economic factors as well as the afrocentric tone of the events. Possible aggravating factors – such as the misplacement of blame and a South African culture of entitlement – also came under scrutiny. In addition, the discussion looked at the need to take into account the perspectives of non-South Africans on African conflicts.

After the symposium, Kovsie students gathered at the Thakaneng Bridge where Vice-Chancellor and Rector, Prof Jonathan Jansen, addressed the group. Carrying posters with ‘No to Xenophobia’ messages, the students then marched across the campus to show their support for anti-xenophobia.

The IRSJ – which the Human Rights Desk forms part of – has spearheaded the No-to-Racism/Yes-to-Equality Campaign launched in March 2015 across all three campuses. Under the guidance of the IRSJ, the Kovsie community has regularly been publicly showing their solidarity against all forms of discrimination.
