Cooperation among competitors in the open-source arena: The case of OpenStack
Jose Teixeira, Salman Mian, Ulla Hytti
Interorganizational interactions are often complex and paradoxical. In this research, we transcend two management paradoxes: competition versus cooperation and open-source versus p…
Geodesics dynamics in the Linet-Tian spacetime with Lambda>0
Irene Brito, M. F. A. Da Silva, Filipe C. Mena +1
We analyse the geodesics' dynamics in cylindrically symmetric vacuum spacetimes with Lambda>0 and compare it to the Lambda=0 and Lambda<0 cases. When Lambda>0 there are two singula…
Cylindrically symmetric models of gravitational collapse to black holes: a short review
Filipe C. Mena
We survey results about exact cylindrically symmetric models of gravitational collapse in General Relativity. We focus on models which result from the matching of two spacetimes ha…
Measurements of top-quark pair differential cross-sections in the channel in collisions at TeV using the ATLAS detector
ATLAS Collaboration
This article presents measurements of differential cross-sections in a fiducial phase-space region, using an integrated luminosity of 3.2 fb of proton--proton dat…
Universal description of channel plasmons in two-dimensional materials
P. A. D. Gonçalves, Sergey I. Bozhevolnyi, N. Asger Mortensen +1
Channeling surface plasmon-polaritons to control their propagation direction is of the utmost importance for future optoelectronic devices. Here, we develop an effective-index meth…
Limits in Categories of Vietoris Coalgebras
Dirk Hofmann, Renato Neves, Pedro Nora
Motivated by the need to reason about hybrid systems, we study limits in categories of coalgebras whose underlying functor is a Vietoris polynomial one - intuitively, the topologic…
