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.”

Kovsies beat Pukke at USSA tennis tournament
2010-01-13

 The Kovsies women’s team that participated in last year’s USSA tennis tournament were, from the left, front: Elrien de Villiers and Nicola Dormehl; middle: Rensia Henning and Christine Keyser; back: Jeanne du Plessis and Elizna Barnard.

 

The men who participated in the tournament were, from the left: Willem Steenkamp, PW Holtzhausen, Duke Munro, Janine de Kock (manager), Marnus Kleinhans (coach), Divan Olivier, HB Steyn and Reon Henning.
 

Last year Kovsie tennis concluded on a highlight when the men’s tennis team of the University of the Free State (UFS) won the USSA tournament that was held in Grahamstown for the first time in twenty years. The UFS women’s team also excelled by going through to the final round, where they had to bow the knee before the team of Stellenbosch University.

The result of these excellent achievements was that two of the five players that were selected for the USSA women’s training group were Kovsies. They are Rensia Henning and Christine Keyser. Elrien de Villiers was selected as the player of the tournament but unfortunately she could not be included in the group because she is a Namibian citizen.

The men’s group existed of eight players, of which four are Kovsies. They are Reon Henning, Duke Munro, Willem Steenkamp and PW Holtzhausen.

Members of the USSA training group will participate in training camps, tournaments and trials to prepare for the Confederation of University and College Sport Association (CUCSA) games (where all the Southern Africa countries participate) in Botswana that will take place from 5-11 July 2010. The training group will also participate in the World Student Games in 2011.

The Kovsies men’s team kick-started last year’s USSA tournament by beating the team from the University of Cape Town with 6-1 and later on the same day beating the team from the University of Johannesburg with 5-1. The next day they beat the team from the Tshwane University of Technology with 7-0 and the team of the University of Pretoria with 5-1. According to Ms Janine de Kock from KovsieSport at the UFS this is an excellent achievement, taking into account that Tukkies had ended in second place at the 2008 tournament.

In the semi-finals Kovsies played against the North-West University and beat them with 4-1. After this triumph in the singles matches the organisers decided that the doubles would not be played.

The women’s team won their matches against the Universities of Pretoria, Cape Town, Rhodes, KwaZulu-Natal and the Tshwane University of Technology. The tournament ended with Kovsies and Maties as the only two unbeaten teams and Stellenbosch University walked away with the laurels. The North-West University did not have a women’s team at the tournament at all.
