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 Habib addresses inequality at public lecture
2014-08-06

 
One of South Africa’s leading political commentators, Prof Adam Habib, gave a public lecture and launched his latest book on the Bloemfontein Campus on Wednesday 30 July 2014. The event was hosted by the Department of Philosophy in association with Wits University Press and The Southern African Trust.

Prof Habib started his lecture by summarising his book, ‘South Africa’s Suspended Revolution: Hopes and Prospects’. “It is basically about: how did we get where we are today, and how do we get out of the mess we are in?” he said.

His book focuses on South Africa’s transition into democracy and the country’s prospects for inclusive development – which formed the basis of his talk. Prof Habib stressed the issue of inequality facing South Africa and discussed the different approaches to addressing the matter.

“The one approach is that it is simply something we have to live with,” he said. “People who believe this live in a bubble. For example, service delivery protests do not happen because of poverty – it happens because of inequality.”

Prof Habib cautioned against not taking the matter seriously. “Inequality went up consistently in South Africa over the last 20 years. This is however not solely a national challenge, but a global challenge. And South Africa is the frontline of the war on inequality.”

He proposed that the expectations of the rich, rather than the poor, should be addressed.
“We need to moderate expectations. But we can’t moderate the expectations of the poor, if not the rich. We can’t ask the poor to sacrifice what the rich won’t.

“South Africa is once again at a moment of reckoning, where we are forced to make hard choices – in order to make the right choices.”
