Book Description
The main theme of the workshop is to discuss problems of nucleosynthesis in the Universe, specifically in connections to the unstable atomic nuclei, which would play a crucial role in explosive burning processes. This subject is strongly backed up by an increasing interest in studying unstable nuclei in nuclear physics.The subjects include primordial nucleosynthesis, Hot-CNO cycle and rapid-proton process, neutrino-induced nucleosynthesis, equation of state of neutron-rich matter etc.

Book Description
The book gathers articles that were exposed during the seventh edition of the Workshop ?Data Analysis in Astronomy?. It illustrates a current trend to search for common expressions or models transcending usual disciplines, possibly associated with some lack in the Mathematics required to model complex systems. In that, data analysis would be at the epicentre and a key facilitator of some current integrative phase of Science.It is all devoted to the question of ?representation in Science?, whence its name, IMAGe IN AcTION, and main thrusts Part A: Information: data organization and communication, Part B: System: structure and behaviour, Part C: Data ? System representation. Such a classification makes concepts as ?complexity? or ?dynamics? appear like transverse notions: a measure among others or a dimensional feature among others.Part A broadly discusses a dialogue between experiments and information, be information extracted-from or brought-to experiments. The concept is fundamental in statistics and tailors to the emergence of collective behaviours. Communication then asks for uncertainty considerations ? noise, indeterminacy or approximation ? and its wider impact on the couple perception-action. Clustering being all about uncertainty handling, data set representation appears not to be the only solution: Introducing hierarchies with adapted metrics, a priori pre-improving the data resolution are other methods in need of evaluation. The technology together with increasing semantics enables to involve synthetic data as simulation results for the multiplication of sources.Part B plays with another couple important for complex systems: state vs. transition. State-first descriptions would characterize physics, while transition-first would fit biology. That could stem from life producing dynamical systems in essence. Uncertainty joining causality here, geometry can bring answers: stable patterns in the state space involve constraints from some dynamics consistency. Stable patterns of activity characterize biological systems too. In the living world, the complexity ? i.e. a global measure on both states and transitions ? increases with consciousness: this might be a principle of evolution. Beside geometry or measures, operators and topology have supporters for reporting on dynamical systems. Eventually targeting universality, the category theory of topological thermodynamics is proposed as a foundation of dynamical system understanding.Part C details examples of actual data-system relations in regards to explicit applications and experiments. It shows how pure computer display and animation techniques link models and representations to ?reality? in some ?concrete? virtual, manner. Such techniques are inspired from artificial life, with no connection to physical, biological or physiological phenomena! The Virtual Observatory is the second illustration of the evidence that simulation helps Science not only in giving access to more flexible parameter variability, but also due to the associated data and method storing-capabilities. It fosters interoperability, statistics on bulky corpuses, efficient data mining possibly through the web etc. in short a reuse of resources in general, including novel ideas and competencies. Other examples deal more classically with inverse modelling and reconstruction, involving Bayesian techniques or chaos but also fractal and symmetry.

Book Description
Since 1963, the Texas Symposia have been a biennial, peripatetic forum for forefront developments on a wide range of topics in relativistic astrophysics, from pulsars to string theory, from the birth of the universe to the death of stars. The 26 plenary lectures, 230 parallel session talks and 265 poster presentations attest to the scientific vitality of this interdisciplinary field.

Book Description
The proceedings of the first meeting on “New Worlds in Astroparticle Physics” focus on the joint field of particle physics and astrophysics. This is a field widely open to both theory and experiment. Important questions of particle physics — from the role of the Higgs scalar to the deconfined QCD phase, the developments beyond the Standard Model and the subtle behavior of neutrinos — are discussed. The same is true for the relevant questions in astrophysics and cosmology — from the fluctuations in the photon background radiation to large scale structure formation, dark matter searches and the origin of cosmic rays at very high energies. The two viewpoints, from the small sizes or from the large scales, are convergent and reveal the same universe: the universe of astroparticle physics.

Book Description
Annotation The July 1994 symposium was an international forum in which scientists working in different research branches connected to nucleosynthesis could discuss the most recent achievements in nuclear astrophysics. The topics addressed range from laboratory work of nuclear astrophysics, especially on reaction rates, to models of nucleosynthesis in single and double stars; from measurements of abundances and isotopic anomalies in pristine meteorites to the reconstruction of the early evolutionary phases of the Solar System; and from optical and radio spectroscopic studies of the composition in stellar atmospheres and circumstellar envelopes to modeling of the global chemical evolution of galaxies.
