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.”

Breyten Breytenbach shares his words and philosophies

The Department of Philosophy at the University of the Free State (UFS) recently hosted Breyten Breytenbach as part of its Colloquium series.

In a packed Odeion theatre, Breytenbach shared his words and views relating to poetry and philosophy. The session was chaired by Prof Pieter Duvenhage from the Department of Philosophy, who noted the symbiotic relationship which exists between the two seemingly distinct disciplines.

Breytenbach is one of South Africa’s best-known literary sons, gaining worldwide recognition for his writings and poetry, as well as his political activism against the erstwhile Apartheid regime. He left the country in 1960 due to Apartheid and settled in Paris where his first collection of poetry was published in 1964. It was the beginning of a prizewinning literary career spanning multiple languages and decades.

He returned illegally in 1975 in order to agitate against the repressive National Party government, but was arrested, spending seven years in prison after being charged with terrorism.

The audience was treated to a reading from an unpublished work from Breytenbach, A letter to my daughter. The lengthy letter outlined Breytenbach's world views, his sense of the creative process, his philosophies and his takes on current and historical events.

A large part of the letter focused on the philosophical and emotional processes involved in writing.“Writing is the travelling of its own landscape; landscapes and rooms that may always have been there,” he said.

He noted that it’s not always an easy process, and that sometimes writers need to explore the abysses, which can be unnerving.

“In this regard it is important to know that emptiness exists,” he said.

He stressed his concern over some of the problems the country currently faces, especially the abuse of state institutions. He was especially worried about the abuse of power. He warned that “power has its own predatory identity,” often abused and misused by those who wield it.

Despite his misgivings, Breytenbach still retains his optimism for the country and its people. He remarked that the country and its many diverse cultures resembles a “fantastic patchwork blanket,” one that should be cherished and protected.
