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.”

Linguistic resourcefulness impresses at 15th Student Symposium on the Natural Sciences
2015-11-26


UFS students walk away with more than half the prizes at this year’s Student Symposium on the Natural Sciences.

This year, the fifteenth annual Student Symposium on the Natural Sciences was hosted on the Bloemfontein Campus by the UFS Departments of Chemistry and Physics, together with the South African Academy for Science and Arts (SAAWK).

According to Dr Ernie Langner, Senior Lecturer in the Department of Chemistry, this symposium provides postgraduate students from all over South Africa the opportunity to present their research in Afrikaans, to learn from each other, receive feedback on their work through the review process, and to build networks. If their abstracts are selected for publication in the Suid-Afrikaanse Tydskrif vir Natuurwetenskap en Tegnologie, it also provides them with further exposure in the broader academic context.

Besides research of the highest quality, this year's symposium had no shortage of linguistic resourcefulness. “Students, accustomed to writing and expressing their research in English, astonished everybody with their beautiful Afrikaans. Outstanding research from honours, master's, and doctoral students was expressed in scientific terminology of the highest standard,” Dr Langner said.

The Student Symposium is the only event (worldwide) where the development of 'elektrostatiese potensiaalkaarte', 'femtosekonde pomp-proef spektroskopie', or 'endokrien-ontwrigtende chemikalieë' is explained step by step. This is where one hears enthusiastic students talking about how hard they are working on 'geïntegreerde drywende sonkragstelsels', or 'geneste virtuele rekenaars binne die wolkstelsel'. The results of hours of hard work in the lab, cold nights behind a telescope, or long midnight sessions in front of the computer, had to be condensed into 15-minute presentations on the synthesis of metal-organic networks, or metal-carbene complexes, the identification of pulsar rhythms, or the refining of rapid-eye technology.

Of approximately forty participants from five universities, eighteen were awarded prizes for their papers and posters. Students from the UFS walked away with more than half of the awards. Jacques Maritz (Physics) and his wife, Elizabeth, (Mathematics and Applied Mathematics) from the UFS were both awarded first place in their respective sessions.
