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 responds to revocation of the accreditation of the SA Doping Control Laboratory by WADA
2017-07-01

The World Anti-Doping Agency (WADA) yesterday informed the South African Doping Control Laboratory (SADoCoL) at the University of the Free State (UFS) that the WADA accreditation status of the laboratory has been revoked.

This revocation does, however, not include the analysis of blood samples for the Athlete Biological Passport for which SADoCoL has been re-accredited in August 2016 and which the laboratory will continue to perform. It also does not impact at all on the testing of urine sport samples by the South African Institute of Drug-free Sport (SAIDS), who will continue to send such samples for testing to other WADA accredited laboratories, while blood samples will be tested at SADoCoL as before.

The revocation follows a year long period of suspension in which the laboratory had to develop its analytical capabilities and instate new systems and methodologies.  “In this period the laboratory worked diligently to realize all of these requirements and according to an inspection team from the WADA Laboratory Expert Group who visited the laboratory in February 2017, much has been done and the Laboratory is in a much better state than it was before the suspension in May 2016,” says prof Marthinus van der Merwe, Director of SADoCoL.

“However, there were certain aspects of these requirements that the laboratory could not achieve within the time-frame stipulated by WADA and therefore the organisation is bound by its rules and regulations to now revoke the accreditation status of the laboratory. Since much effort and resources have been invested in the laboratory in the last two years, the management of SADoCoL together with senior leadership of the UFS decided to go ahead and finalise all development in order to re-apply for WADA accreditation,” says prof van der Merwe. 

“The UFS fully acknowledges the hard work of SADoCoL during the period of development and is committed to support the laboratory in its endeavors to re-attain its status within the very specialised and highly regulated community of world-wide doping control laboratories.  The premium goal of the laboratory is still to fully serve the sporting community of South Africa and Africa according to the WADA guidelines for anti-doping control in Sport and it is confident to attain that with the support of all role players in this field,” says Prof Witthuhn, Vice-Rector: Research at the UFS.
