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.”

Department at the UFS receives special visitors

The Department of Old Testament in the Faculty of Theology at the University of the Free State (UFS) has for the first time received a visit from two guest professors from the Katholieke Universiteit Leuven (KU) in Belgium who are presenting undergraduate lectures.

What makes the visit even further unique is that the guest professors are a married couple who specialise in the Old Testament.

“Proff. Hans Ausloos and Bénédicte Lemmelijn are visiting the faculty for about a month to present undergraduate programmes. They are part of a co-operative agreement between the UFS and the KU Leuven. This is also a good way of giving our students exposure to European experts,” says Prof. Snyman, Head of the Department of Old Testament at the UFS.

The couple and their three children, Matthias (10), Elke (8) and Ruben (6), are staying in Prof. Daan Pienaar’s house for the duration of their stay. Prof. Pienaar is a retired professor in Biblical Science at the UFS. The children are at school in Universitas Primary School for the duration of the family’s stay in Bloemfontein. “The headmaster was very kind and provided them with school uniforms out of the school’s second hand clothing shop, of which they will not part easily as they do not wear school uniform in Belgium,” says Prof. Lemmelijn.

Proff. Lemmelijn and Ausloos cannot stop talking about the charm of the university’s Main Campus. “In Leuven the university is part of the city and the university buildings are situated amongst the city buildings. We do our shopping while the students move from one class to the other! Here, the university is a town on its own and the students are given the opportunity to socialise in a protected environment,” says Prof. Lemmelijn.

The couple is also just as impressed with Bloemfontein. “The safety issue in South Africa is accentuated in such a way in Europe that we are astounded by the peaceful and friendly atmosphere of the city. We are also surprised with the shopping centres that are under one roof. In Belgium the shops are situated far apart,” says Prof. Lemmelijn.

The couple finds the living costs – especially food – to be quite expensive. “Some basic food is even more expensive than it is in Belgium,” says Prof. Ausloos.

Over and above their commitment to lecture, the couple is also busy with research on the Greek translation of the 12 Small Prophets in co-operation with Prof. Snyman.

“This is the first time that lecturers from the KU Leuven visit the Department of Old Testament for such a long time and are part of the normal curriculum. It is interesting to note that the teaching modules between the two departments resemble each other in such a way that lectures which are presented in Leuven are also repeated here,” says Prof. Snyman.

Both Proff. Ausloos and Lemmelijn are professors in the Old Testament within the Bible Science Investigation Unit of the KU Leuven. They publish articles internationally on the editorial and text criticism of the Old Testament and are involved with international investigative programmes such as the Hexapla Project and Septuaginta-Deutsch. Prof. Ausloos is director of the Leuvense Centre for Septuagint Studies and Textual Criticism and Prof. Lemmelijn is an associate in the centre. Together they have published several financed investigative projects on the characterising of the translation technique of the Greek Bible translation.
