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 supports SAASTA in science initiative

The National Astronomy Quiz for Grade 7 learners was recently hosted at the Boyden Science Centre, which is managed by the University of the Free State’s (UFS) Department of Physics. It was also Boyden and the UFS’s Department of Physics that coordinated the Free State leg of the competition. The Free State Department of Education was also on board to ensure smooth arrangements for the preliminary, as well as the first two official rounds of the competition.

The competition is hosted by the South African Agency for Science and Technology Advancement (SAASTA), an agency of the National Research Foundation (NRF).

Ninety schools from all over the Free State took part in the first official round. Eighteen schools qualified for the second round, once again with a balanced geographic coverage of the province.

During the second round, eight schools made it to the third round. Two of these schools were from Bloemfontein and the other six from other towns and rural areas in the Free State.

The third round and provincial finals took place at the Boyden Science Centre. The schools qualifying for the final round were Hennenman Primary School, Unicom Primary School (Tweespruit), Voorwaarts Primary School (Kroonstad) and Fichardt Park Primary School (Bloemfontein).

As a pleasant surprise, Unicom Primary School, a less well-known school from a smaller town, won the Free State finals. It was the first time this had happened since the inception of the competition.
