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.”

UFS History lecturer becomes Visiting Fellow at Harvard

Prestige Scholar and lecturer of African/South African History at the UFS, Dr Chitja Twala, was recently accepted as a Visiting Fellow at the Harvard Graduate School of Arts and Sciences (GSAS).

A Visiting Fellow status is available to individuals holding a doctoral degree to pursue independent research at Harvard. The Fellowship is for non-degree purposes but aims at the enhancement and further intellectual development of those involved. It focuses on enrichment and development programmes.

Twala was appointed in the Department of History at the UFS in the beginning of 2003. His research field is Liberation History, with specific reference to the liberation movements on the SADC region. He has published extensively on this field and presented papers in local and international conferences.

“I applied (to Harvard GSAS) in April 2014 for the Fellowship through the South Africa Harvard Fellowship Programme,” says Twala.

“After being successful in the interviews conducted by the GSAS panel in July 2014, I had to apply for admission in the Department of African and African American Studies at Harvard, and got accepted for the Fall Semester of 2015.”

At Harvard, Twala will be mentored by Prof Emmanuel Akyeampong (African History Expert).

“Firstly, my main assignment will be to grasp a much deeper theoretical knowledge/framework in historical studies and a broader repertoire of methodologies in the field of African History. Secondly, if time permits, I will be presenting seminars and attending some in a very challenging, stimulating, and intellectually demanding environment where my ideas can be tested and expanded. Thirdly, I will be exposed to new trends as far as African historiography is concerned. Lastly, I will informally engage and exchange some ideas with some experts in the field of African History.”

The programme was recommended to Twala by the Vice-Chancellor and Rector, Prof Jonathan Jansen and Prof Ian Phimister, Centre for Africa Studies Senior Professor at UFS.

“As per the priorities of the Prestige Scholarship Programme, the Fellowship will assist in inculcating in me the intellectual breadth and depth required to pose critical questions and generate ground-breaking knowledge for History as a discipline. It is important for the UFS to establish and sustain international networks with other leading universities and scholars around the world.

“I applied for this Fellowship in order to advance further and broaden the scope in the three areas of scholarship in higher education: discovery, teaching, and public engagement,” says Twala.

Twala will be leaving for Harvard by mid-August and will return by the end of December 2015.
