A very attractive feature of the theory of general relativity is that it is a perfectexampleofa“falsi?able”theory:notunableparameterispresentinthe theory and therefore even a single experiment incompatible with a prediction of the theory would immediately lead to its inevitable rejection, at least in the physical regime of application of the aforementioned experiment. This fact provides additional scienti?c value to one of the boldest and most fascinating achievements of the human intellect ever, and motivates a wealth of e?orts in designing and implementing tests aimed at the falsi?cation of the theory. The ?rst historical test on the theory has been the de?ection of light gr- ing the s...
This Handbook provides a comprehensive account of contemporary Israeli diplomacy and analyses the changing dynamics of Israel’s bilateral relations with other states and the international community over the past seventy-five years. Research into Israeli foreign policy has been largely sidelined by debates over security, domestic politics and the Israeli–Palestinian conflict. This Handbook addresses the gap in the literature. Comprising 31 essays written by leading scholars of Israel, the Handbook explicates how domestic, societal and economic interests, together with changing Israeli narratives of identity and location, shape and impact Israeli foreign policy. It illustrates how those fa...
The aim of the inaugural meeting of the Sant Cugat Forum on Astrophysics was to address, in a global context, the current understanding of and challenges in high-energy emissions from isolated and non-isolated neutron stars, and to confront the theoretical picture with observations of both the Fermi satellite and the currently operating ground-based Cherenkov telescopes. Participants have also discussed the prospects for possible observations with planned instruments across the multi-wavelength spectrum (e.g. SKA, LOFAR, E-VLT, IXO, CTA) and how they will impact our theoretical understanding of these systems. In keeping with the goals of the Forum, this book not only represents the proceedings of the meeting, but also a reflection on the state-of-the-art in the topic.
This book is a collation of the contributions presented at a major conference on isolated neutron stars held in London in April 2006. Forty years after the discovery of radio pulsars it presents an up-to-date description of the new vision of isolated neutron stars that has emerged in recent years. The great variety of isolated neutron stars, from pulsars to magnetars, is well covered by descriptions of recent observational results and presentations of the latest theoretical interpretation of these data.
Existing international law is capable to govern the “war on terror” also in the aftermath of September 11, 2001. The standards generally applicable to targeted killings are those of human rights law. Force may be used in order to address immediate threats, preventive killings are permitted under strict preconditions but targeted killings are prohibited. In the context of armed conflicts, these standards are complemented by international humanitarian law as lex specialis. Civilians may only be targeted while directly taking part in hostilities and posing a threat to the adversary. Also in Israel and the Occupied Territory, these standards apply. Contrary to the Israeli Supreme Court’s view, international humanitarian law is not complemented by human rights law, but human rights law is – to some degree – complemented by international humanitarian law. According to these standards, many killings which would be legal according to the Israeli Supreme Court violate international law.
Neutron stars, whether isolated or in a binary system, display a varied and complex phenomenology, often accompanied by extreme variability of many time scales, which takes the form of pulsations due to the object rotation, quasi-periodicities associated to accretion of matter, and explosions due to matter accreted on the surface or to starquakes of highly magnetized objects. This book gives an overview of the current observational and theoretical standpoint in the research on the physics under the extreme conditions that neutron stars naturally provide. The six chapters explore three physical regions of a neutron star: the space around it, where accretion and pulsar companions allow testing of general relativity its surface, where millisecond pulsation and X-ray burts provide clues about general relativistic effects and the equation of state of neutron matter its interior, of course, inaccessible to direct observations, can nevertheless, be probed with all observational parameters related to neutron star variability.
This conference examines the progress in the field of interacting binaries discussing a number of relevant astrophysical problems regarding the interaction between stars in binary systems, such as the physics of neutron stars and black holes that accrete matter from their companion stars and the study of the end points of stellar evolution, like supernovae and gamma-ray bursts. This proceedings provides an updated overview of both observations and theory. Topics include: compact binaries in globular clusters, millisecond binary pulsars, supernovae from massive binary systems and GRBs, accretion on black holes and microquasars, accretion on white dwarfs and novae, rapid variability and secular evolution of LMX-Ray binaries, supernovae type Ia, as well as secular evolution of high-mass x-ray binaries.

The distinctions and similarities among Roman, Jewish, and Christian burials can provide evidence of social networks, family life, and, perhaps, religious sensibilities. Is the Roman development from columbaria to catacombs the result of evolving religious identities or simply a matter of a change in burial fashions? Do the material remains from Jewish burials evidence an adherence to ancient customs, or the adaptation of rituals from surrounding cultures? What Greco-Roman funerary images were taken over and "baptized" as Christian ones? The answers to these and other questions require that the material culture be viewed, whenever possible, in situ, through multiple disciplinary lenses and i...
