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.”

Music was always something this singing sensation wanted to do from a very early age.

Sonet du Plessis, more famously known by her stage name, Hailey Clark, is a third-year BA Drama and Theatre Arts student at the University of the Free State (UFS). Her electronic pop debut album, titled Deurmekaar, was finally launched after a year of hard work and sacrifice.

Success in English and Afrikaans

Hailey, whose album features Afrikaans and English songs, says her music is influenced and inspired by a variety of local sounds and artists. “Dirk van der Westhuizen and Refentse – a new and upcoming artist – are two of the locals I look up to,” she says.

Reaching success at such a young age is the result of setting goals and achieving them. “Success is when you grow as a person and an artist in your music. You need to enjoy every moment of what you do and share it with other people,” Hailey says.

Future music producer and actress

With a bright future ahead of her, Hailey wants to become a full-time musician, but also wants to focus on acting, especially in films. “I want to perform as much as possible and hopefully become a music producer. I also have plans to do some acting as well.”

For all those who dream of becoming a musician, it’s hard work, Hailey says. “You have to know it is something you want to do and you have to commit to it. If it is what you want, keep focused and surround yourself with positive and encouraging people.”
