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.”

Lecture focuses on how Marikana widows embody the transformative power of art

"When I got the news of my husband is dead, I put my hands above my head, as you see me in this picture. I could not bear the ache in my heart." - Makopane Thelejane

A woman looks down on a canvas covered in thick layers of red, dark shadows falling across her face. A brief moment that captures the silently-devastating aftermath of the Marikana massacre that bled into the lives of 34 widows.

It is this silent trauma that was at the centre of the last instalment of the Vice-Chancellor’s Lecture Series for 2015. “These stories of the Marikana widows are important. It is these stories of silence that live behind the spectacular scenes of the violence,” Prof Pumla Gobodo-Madikizela, Senior Research Professor in Trauma, Forgiveness, and Reconciliation Studies at the University of the Free State (UFS) said at the event.

Panel
The lecture, which took place on Monday 27 July 2015 on the Bloemfontein Campus, took the form of a panel discussing the theme of “Speaking wounds: voices of Marikana widows through art and narrative”. The panel consisted of members from the Khulumani Support Group, including Dr Marjorie Jobson (National Director) and Judy Seidman (Sociologist and Graphic Artist), as well as Nomfundo Walaza, former CEO of the Desmond Tutu Peace Centre.

"Then this dark time came, a dark cloud over me. It made me to have an aching heart, which took me to hospital, from losing my loved one, my husband, in such a terrible manner. " - Betty Lomasontlo Gadlela

Trauma made visible
In a project initiated by Khulumani, the Marikana widows were encouraged to share their trauma through painting body maps – in which the widows depicted their own bodies immersed in their trauma – and narrating their personal stories. Throughout the workshops, the focus always remained on the women. As Siedman put it, “the power of this process is rooted in the participants. The statements of what the participants experienced is what’s important.”

Initially silenced and isolated, this group of women has now moved “into a space where they have become connected to each, and stand up for each other in the most powerful ways,” Dr Jobson said. “Our work is conceptualised in terms of giving visibility and voice to the people who know what it takes to change this country; to change this struggle.”

The transformative power of art and narrative
During her response, Walaza pointed out “how art and narrative can transform traumatic memory and become integrated in the survivors’ life story.” This gives individuals the opportunity, she said, “to step into a space of mutual listening and dialoguing in which people bond together.”

Co-hosted by Prof Gobodo-Madikizela and the UFS Institute for Reconciliation and Social Justice, the lecture series forms part of a five-year research project funded by the Andrew W. Mellon Foundation.
