Most of the tweets that users exchange on Twitter make implicit mentions of named-entities, which in turn can be mapped to corresponding Wikipedia articles using proper Entity Linking (EL) techniques. Furthermore, some of those become trending entities on Twitter due to a long-lasting or a sudden effect on the volume of tweets where they are mentioned. We argue that the set of trending entities...

Several ranges encompassing more than 35,000 km 2 of Sonora, Mexico, contain distinctly lineated and foliated granitic and metamorphic rocks that constitute the lower plates of metamorphic core complexes. Penetrative deformation is characterized by gently dipping mylonitic foliation across which northeast trending stretching lineation is everywhere developed. Prominent northwest trending fractu...

Western Turkey has been dominated by N–S extension since the Early Miocene. The timing and cause of this N–S extension and related basin formation have been the subject of much debate, but new data from the Bigadiç borate basin provide insights that may solve this controversy. The basin is located in the Bornova Flysch Zone, which is thought to have formed as a major NEtrending transform zone d...

We present time resolved optical data acquired by the TAROT automated observatory on the afterglow of GRB 050525a from 6 to 136 min after the GRB. We find evidence for a rapid re-brightening of 0.65 mag of the afterglow at ∼33 min after the GRB. The decay slope α is 1.14 ± 0.07 in the first part and is 1.23 ± 0.27 after the re-brightening event. The afterglow of GRB 050525a is the third known a...

The diplomatic ties between Africa and Southeast Asia (SEA) have historically been sporadic and erratic. The only country in the SEA that the first decades after independence maintained a relatively narrower link to some African countries was Indonesia, because of political and ideological reasons. Today, trade has gained momentum, being South Africa, Egypt and Nigeria, the largest trading part...

An address is a common reference for a multitude of information. In South Africa, multiple address datasets are developed and maintained by various public and private organizations with little or no cooperation on data sharing. We identified motivators and barriers for address data sharing in South Africa through case studies of three typical organizations, which prepare, distribute and use add...

The approval in July 2001 by the Organisation of African Unity (OAU) of the “New African Initiative” and a commitment soon afterwards by the world’s richest countries (G8) to launch a detailed development plan for Africa over the next year, can justly be regarded as a major boost for South African President Thabo Mbeki’s vision of an “African Renaissance” as the cornerstone for an “African Cent...

Two global-scale mantle convection cells presently exist on Earth, centred on upwelling zones in the South Pacific Ocean and northeast Africa: one cell (Panthalassan) contains only oceanic plates, the other (Pangaean) contains all the continental plates. They have remained fixed relative to one another for s 400 Ma. A transverse (Rheic^Tethyian) subduction system splits the Pangaean cell. Poloi...
