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.”

A Kovsie parade through Bloemfontein's streets

The community of Bloemfontein came out in numbers to watch the annual Kovsie Rag procession on Saturday 1 February 2014. Young and old lined the roads around the Bloemfontein Campus to get a glimpse of the colourful floats moving through the city’s streets. Onlookers showed their support for the UFS’s charitable fun drive, dropping coins in the money tins of first-year students who made their way through the crowds.

Celebrating the hard work of students who spent hours building floats, festivities kicked off with a morning parade to Heidedal and Mangaung. Here the Rag Office distributed 10 000 meals to members of the community.

With a beloved Hollywood panda as their inspiration, JBM, Soetdoring and Imperium residences were crowned winners of the movie-themed float-building competition later the evening. Their Kung Fu Panda float led the way as the main procession made its way to the Chevrolet Cricket Stadium for a night of celebration with music stars Mango Groove, Zakes Bantwini and Robbie Wessels.  

Mango Groove had the audience on their feet playing well-known hits like Special Star, Moments Away and Hometalk. Robbie Wessels and Bantwini also didn't disappoint, with the audience stomping feet to their music. In addition, partygoers were treated to an amazing fireworks display that lightened up the Bloemfontein night sky.

Float-building results: 

  • Overall winners: JBM, Soetdoring and Imperium 
  • Winners Pool A: JBM, Soetdoring and Imperium
  • Winners Pool B: Welwitchia and Tswelopele 

The overall assessment of floats was made up of 100 points. The impression of the floats on the little ones was very important, as children judges awarded 25% of the score. They gave a mark out of 10 and it was converted to a mark out of 25.

The assessment by the adult judges counted for 75 points. The criteria were as follows:

  • General impression and colour: 25 points
  • Detail: 25 points
  • Did the float complement the theme: 15 points
