The converse problem for the multipotentialisation of evolution equations and systems
Norbert Euler, Marianna Euler
We propose a method to identify and classify evolution equations and systems that can be multipotentialised in given target equations or target systems. We refer to this as the {\i…
Effects of high pressure on the physical properties of MgB2
T. Prikhna, W. Gawalek, Ya. Savchuk +27
The synthesis of MgB2-based materials under high pressure gave the possibility to suppress the evaporation of magnesium and to obtain near theoretically dense nanograined structure…
A study of the distant activity of comet C/2006 W3 (Christensen) using Herschel and ground-based radio telescopes
D. Bockelée-Morvan, P. Hartogh, J. Crovisier +35
Comet C/2006 W3 (Christensen) was observed in November 2009 at 3.3 AU from the Sun with Herschel. The PACS instrument acquired images of the dust coma in 70- and 160-micrometers fi…
Have neutron stars a dark matter core?
Paolo Ciarcelluti, Fredrik Sandin
Recent observational results for the masses and radii of some neutron stars are in contrast with typical observations and theoretical predictions for "normal" neutron stars. We pro…
Positive Supercompilation for a Higher-Order Call-By-Value Language
Peter A. Jonsson, Johan Nordlander
Previous deforestation and supercompilation algorithms may introduce accidental termination when applied to call-by-value programs. This hides looping bugs from the programmer, and…
Accessibility of color superconducting quark matter phases in heavy-ion collisions
D. B. Blaschke, F. Sandin, V. V. Skokov +1
We discuss a hybrid equation of state (EoS) that fulfills constraints for mass-radius relationships and cooling of compact stars. The quark matter EoS is obtained from a Polyakov-l…
