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.”

Meet the person behind the new #FaceOfFacebook
2016-05-19

Reuben “R” Davids

The votes have been counted, and we have a winner! After much excitement and a fairly close contest, Reuben “R” Davids emerged victorious from the top five contestants selected by our panel of judges. We chatted with the vibrant and enthusiastic Mr Davids to get a sense of the person who will be our Facebook ambassador for the next year.

What does the “R” stand for?

“Interestingly, some also know me as Vuyo. It's not a name on my birth certificate or anything; I just really like it. And I also coincidentally found out that it means “joy/happiness”, and I do enjoy being happy.”

What is your field of study, and how far along are you?

“I am pursuing a career in the economics field as a third-year BCom Accounting student in the Faculty of Economic and Management Sciences here at the University of the Free State.”

Are you originally from Bloemfontein?

“Yes, born and bred. I've been a Bloem Kid since day one.”

How is it that you ended up here, studying at the UFS?

“The UFS has always been one of my favourite universities. During my high school period, I was constantly exposed to people from my neighbourhood as well as schoolmates who performing excellently here at UFS, and it didn't go unnoticed. So I have always been drawn to the prestige that UFS carries.”

Which residence are you in, and what do you enjoy most about res life?

“I currently stay at home with the family, but for my first 2 years of study I resided at ConLaurês. What I enjoyed the most about res life is the freedom and independence that you get. It also enables one to participate in campus life much easier. It actually helps one grow and mature into the adult you're supposed to become with all the challenges and responsibilities that you're faced with.”

What do you hope to accomplish during your term as the #FaceOfFacebook?

“I enjoy the art of presenting (as well as being an MC), and being the #FaceOfFacebook will enable me to exercise that skill. Also, my interaction skills will be exercised. That being said, I would like to have those skills developed further by the end of my term as #FaceOfFacebook.”

What is your motivation in your studies, in taking part in this contest, and in life?

“I am an adrenaline junkie. I like taking on challenge; so what I normally do is I set a certain goal for myself and then take on the challenge to achieve that goal. That's my number one motivating factor. And I think I'm also inspired by the failures and successes of myself and of those around me.”

Reuben has already been featured in a #PeopleOfKovsies post on Facebook, and appeared in his first Facebook video covering the Open Day on our Bloemfontein Campus.
