Sentence mood constitution and indefinite noun phrases
Sentence mood in German is a complex category that is determined by various components of the grammatical system. In particular, verbal mood, the position of the finite verb and the wh-characteristics of the so called 'Vorfeld'-phrase are responsible for the constitution of sentence mood in German. This article proposes a theory of sentence mood constitution in German and investigates the interaction between the pronominal binding of indefinite noun phrases which are semantically analyzed as choice functions. It is shown that the semantic objects determined by sentence mood define different kinds of domains which have to be uniquely accessible as the range of the choice function. The various properties of the pronominal binding of indefinites can be derived by the interplay of the proposed theoretical notions
Superconducting electronics
During the last decades superconducting electronics has been the most prominent area of research for small scale applications of superconductivity. It has experienced quite a stormy development, from individual low frequency devices to devices with high integration density and pico second switching time. Nowadays it offers small losses, high speed and the potential for large scale integration and is superior to semiconducting devices in many ways ¿ apart from the need for cooling by liquid helium for devices based on classical superconductors like niobium, or cooling by liquid nitrogen or cryocoolers (40K to 77K) for high-Tc superconductors like YBa2Cu3O7. This article gives a short overview over the current state of the art on typical devices out of the main application areas of superconducting electronics
Collapse of Flow: Probing the Order of the Phase Transition
We discuss the present collective flow signals for the phase transition to
the quark-gluon plasma (QGP) and the collective flow as a barometer for the
equation of state (EoS). We emphasize the importance of the flow excitation
function from 1 to GeV: here the hydrodynamic model has predicted the
collapse of the -flow at GeV and of the -flow at GeV. In the latter case, this has recently been observed by the NA49
collaboration. Since hadronic rescattering models predict much larger flow than
observed at this energy, we interpret this observation as potential evidence
for a first order phase transition at high baryon density .Comment: 12 pages, 10 figures, To appear in the proceedings of 4rd

Shock waves in nuclear matter : proof by circumstantial evidence
In the present paper we develop the essential theoretical tools for the treatment of the dynamics of High Energy Heavy Ion Collisions. We study the influence of the nuclear equation of state and discuss the new phenomena connected with phase transitions in nuclear matter (pion condensation). Furthermore we investigate the possibility of a transition from nuclear to quark matter in High Energy Heavy Ion Collisions. In this context we discuss exotic phenomena like strongly bound pionic states, limiting temperatures, and exotic nuclei
