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.”

Forgive and forget? Or remember and retaliate?
2015-10-08

Cover of the novel Kamphoer

Fact and fiction came together at the Bloemfontein Campus recently to discuss the traumatic repercussions of the South African War. The event forms part of a three-year project – headed by Prof Pumla Gobodo-Madikizela (University of the Free State Trauma, Forgiveness, and Reconciliation Studies) – which investigates transgenerational trauma in the aftermath of the South African War.

The discussion explored the theme, ‘Working through the Past: Reflections on the novel Kamphoer’.

Together, Emeritus Prof Chris van der Merwe (University of Cape Town) and the author of the novel, Dr Francois Smith (University of the Free State, Department Afrikaans and Dutch, German and French), engaged in a thought-provoking, insightful conversation, tracing themes of trauma and issues of forgiveness presented in Kamphoer. Prof Van der Merwe and Dr Smith demonstrated how both fiction and historical fact can inform our present, and guide us into the future.

discuss the novel Kamphoer and how the book relates to
current issues of transgenerational trauma.

“On a societal level,” Prof Van der Merwe said, “we need to work through trauma by putting it into words, and putting it into a narrative.” When it comes to historical trauma, should we forgive and forget, though? Or rather remember and retaliate? Neither, proposed Prof Van der Merwe. “What I want to plead for is the difficult challenge: remember and forgive.” But Prof Van der Merwe also pointed out that, although forgiveness blesses both the giver and receiver, it is an ongoing process.

Dr Smith agreed wholeheartedly. “One of the discoveries of my book is that forgiving is a continuous process. It’s not something that gets completed at a particular stage in your life. By the same token, you can’t say that you are ever able to leave the past behind.” These issues of trauma, forgiveness, the past versus the present, remembering and forgetting are all integral questions confronting the main character of the novel, Susan Nel .

They are also questions we, as a nation, are currently confronted with, too.

“At this moment in our society,” Prof Van der Merwe said, “we have enough killers. We have a greater need now for caring nurturers.”
