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 cardiac team does pioneering work

Members of the University of the Free State’s (UFS) Cardiac team had various achievements at national and international level this year. The Robert WM Frater Cardiovascular Research Centre in the Faculty of Health Sciences has commenced with a pioneering research project regarding idiopathic dilating cardiomyopathy.

With an Afrocentric research focus, Prof Francis Smit, Head of the Department of Cardiothoracic Surgery at the UFS and Head of the Frater Centre, describes dilating cardiomyopathy as a heart muscle disease that is quite common, particularly among people of African descent. The disease weakens the heart muscle, which in turn leads to heart failure.

“To date there is no curable treatment for this condition, and 50% of patients who have shown heart failure, died within a period of five years. The causes of this condition have been unknown in the majority of patients. But over the past few years major strides have been made, where virus infections of the heart muscle, or myocarditis, have been identified as a possible underlying cause. Various genetic diseases are also linked to it,” says Prof Smit.

According to Prof Mokoali Makotoko, Head of the Department of Cardiology, more than 1 500 new cases of heart failure are identified at the Universitas Academic Hospital annually, of which approximately 30% are attributed to cardiomyopathy. “With the use of endomyocardial biopsies, the team hopes to treat viruses unique to Southern Africa, as well as other underlying causes of dilated cardiomyopathy.”

The study is a project that flows from Prof Makotoko’s PhD. The project is being run with Prof Heinz-Peter Schultheiss of the Charité University and the Institute for Cardiac Diagnostics and Therapy in Berlin, Germany.
