A few simple if not obvious statements at the end of the conference: This was an useful conference. It has shown us the rapidly widening scope of the binary star research which now extends in its applications from the realm of planets to black holes and binary galactic nuclei. The binary star domain appears to be -- in parallel to searched for extra-solar planets and star formation -- the most active areas of stellar astrophysics. I am glad I attended this conference.
The symposium has shown the dynamism of this rapidly evolving discipline. I shall concentrate here on some highlights and some complementary informations. I conclude on open questions with some perspectives on solar & stellar activity and related planets.
I summarise the concluding remarks I gave at the Multifrequency Behaviour of High Energy Cosmic Sources - XIII Workshop. That was not a summary talk and was meant to be provocative. I first give what I think the main message of the workshop was, then
The highlights of the conference: The Legacy of Bruno Pontecorvo: the Scientist and the Man, held in Roma, Universit`a La Sapienza, 11-12 September, 2013, are summarised and illustrated.
I review the reason for considering the prime purpose of the program of measurements of the fundamental parameters of cosmology to be the tests of cosmological models. I comment on the philosophy by which we are approaching this goal, offer an assess
Quantum networks will provide multi-node entanglement over long distances to enable secure communication on a global scale. Traditional quantum communication protocols consume pair-wise entanglement, which is sub-optimal for distributed tasks involvi
