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 staff and students clean campus together

A group consisting of students, staff and members of the management team of the University of the Free State (UFS) proved that they are not only talking about sustainability and the importance of keeping the campus clean, but they actually put their words to action by taking up a garbage bag and helping to pick up garbage.

According to Ms Martie Bitzer, Head of the Sustainability Committee of the UFS, the UFS followed the lead of higher education throughout the world by joining the movement for sustainability and took the plunge in addressing sustainability issues with both short- and long-term planning. One of the short-term plans is to make staff and students aware of the importance of a “green” lifestyle. This week’s activities, including the picking up of garbage and planting a tree on the Bloemfontein Campus of the UFS, is the result thereof.

Prof. Jonathan Jansen, Vice-Chancellor and Rector of the UFS, who also helped to pick up garbage, told the group of staff and students that many universities around the world are implementing sustainability initiatives and are keeping their campuses clean, because they care for the environment. He thanked the group for their contribution to this process.

“By cleaning up around us, we show respect towards ourselves and towards our campus,” said Prof. Jansen.

To encourage students to keep the campus clean, Student Affairs at the UFS will launch a competition to see which residence can pick up the most garbage on 8 September 2011. A Clean Thakaneng Bridge Campaign will also be launched later on.
