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.”

SARChI Chair on disease resistance and quality in field crops awarded in UFS Department of Plant Science
2016-02-01

Description: SARChI Chair Tags: SARChI Chair

Prof Labuschagne

A South African Research Chairs Initiative (SARChI) chair has been awarded in the Department of Plant Sciences at the University of the Free State (UFS). The chair will be headed by Prof Maryke Labuschagne, and will focus on crop quality breeding and disease resistance in field crops.

The disease resistance research by the chair will be headed by Prof Zakkie Pretorius. The disease resistance breeding will be a continuation of the internationally-acclaimed wheat rust research that Prof Pretorius has been conducting during his career.

The quality breeding will focus on crop protein quantity and quality as well as on iron, zinc, and beta carotene biofortification of staple crops such as wheat, maize, and cassava.

Prof Labuschagne believes that food security is one of the key factors for stability and prosperity on the continent. Her research and that of her students focuses on the genetic improvement of food security crops in Africa, including such staples as maize and cassava. “These crops are genetically improved for yield, drought tolerance, disease, and insect resistance, as well nutritional value,” she said.

Last year, one of  Prof Labuschagne’s PhD students, Bright Peprah, received an award for $473 000 from the competitive Program for Emerging Agricultural Research Leaders (PEARL) of the Bill and Melinda Gates Foundation for his project on improving the beta-carotene content in cassava.

Prof Labuschagne also received the prestigious ‘Continental Lifetime Achiever Award’ from Africa’s Most Influential Women in Business and Government Programme (MIW) last year for her commitment and continuous contributions to food security. She is an NRF-rated researcher, and author or co-author of over 160 articles in accredited journals.

Research Chairs have been designed by the Department of Science and Technology, together with the National Research Foundation, to attract and retain excellence in research and innovation at South African public universities.
