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.”

UFS law students sit in on exceptional case in the Supreme Court of Appeal
2011-09-21

 
At the Supreme Court of Appeal were, from left to right: Dr Beatri Kruger, lecturer in our Department of Criminal and Medical Law at the Faculty of Law; Adv. Ann Skelton, Amicus Curiae instructed by the Restorative Justice Centre; Ms Matsepo Soko, post-graduate student in Criminal Law; and Prof. Annette van der Merwe from the University of Pretoria.

Fourth-year and master’s-degree students, from our Faculty of Law, had the privilege of attending the hearing of one of their prescribed cases in the module, Criminal Law, namely the State versus Tabethe, in the Supreme Court of Appeal. Apart from the fact that they could attend the hearing, the students were also addressed by experienced legal experts, Adv. Ann Skelton (amicus curiae, instructed by the Restorative Justice Centre) and Prof. Annette van der Merwe from the University of Pretoria, on the broad outlines of the case.

In this case, the accused was found guilty of raping his fifteen-year-old stepdaughter. The court imposed a sentence of ten years’ imprisonment, suspended in full, but with certain conditions. The conditions include 800 hours’ community service and stipulate that the accused has to follow a rehabilitation programme and that he has to give 80% of his income to the family in order to support the victim and her family.
 
This was the first rape case where, in following a restorative justice approach, exceptional conditions were imposed to address the interests of the victim who wants to proceed with her studies. The State appealed against the sentence.
 
Dr Beatri Kruger, lecturer in our Department of Criminal and Medical Law, who prescribed this case for the students, said, ‘The law students were indeed privileged to attend this auspicious and enriching occasion, which provided them with an insightful experience of how the law works in practice.’
