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.”

Prof. Jansen is a "charmer", say students

CHARMING, DOWN TO EARTH, STREEWISE … these are some of the words staff and students on the Qwaqwa Campus used to describe our Rector and Vice-Chancellor, Prof. Jonathan Jansen during his recent courtesy visit to the campus.

Prof. Jansen easily mingled and joined in conversations like a person who was acquainted to the groups of friends that he spoke to. Topics ranged from “girlfriends and boyfriends, how easy or difficult that course was, this and that party”, and of course serious academic talk.

“Prof. Jansen jokingly asked me about my white coat and whether I was a medical doctor. And when I answered that I am a cleaners’ supervisor, he became more interested in what I had to tell him,’ said Ms Dineo Mtombeni, a Maintenance Services supervisor.

“He continued to praise me and my colleagues for the cleanliness on campus and I must say he showed that he is a caring person, despite his position,” concluded Ms Mtombeni.

“I was happy to see Prof. Jansen chatting informally with students and staff. I asked him what he thought of our campus and he said he would know it better once he started teaching here once or twice a week,” said Mr Samuel Mensah, Economics lecturer.

“I then invited him to present some Economics classes and he roared with laughter about the difficulty of dealing with our micro and macro aspects of the subject and I asked him to keep it down as that would justify my students’ fear of the subject,” laughed Mr Mensah.

“He is a nice and friendly person,” said a 19-year-old Bachelor of  Commerce student Masebabatso Mofokeng.

“We shared a joke or two with him and it was one of our best experiences here on campus,” added friends, Sindiswa Masango (19) and Mbali Phakathi (19), who are also studying for their Bachelor of Commerce degrees.

A Bachelor of Education student, Nokubonga Mdlalose (20) described Prof. Jansen as a ‘charmer’.

“He is generous with his time, despite the high position that he occupies. He is approachable, friendly, charming, cool, calm and collected,” said Nokubonga.

“He asked me about my studies and I told him I wanted to make a difference in as far as teaching science is concerned. He was very interested in my Biology experiments and I am so glad I met him,” concluded Nokubonga.
