We investigate the relevance of the gravitational-wave driven r-mode instability for strange stars. We find that the unstable r-modes affect strange stars in a way that is quite distinct from the neutron star case. For accreting strange stars we show that the onset of r-mode instability does not lead to the thermo-gravitational runaway that is likely to occur in neutron stars. Instead, the stra...

Strange stars that are entirely made of strange quark matter (SQM) have been long ago proposed as an alternative to neutron stars (e.g., [1, 2]). The possible existence of strange stars is a direct consequence of the conjecture that SQM composed of roughly equal numbers of up, down, and strange quarks plus a smaller numbers of electrons (to neutralize the electric charge of the quarks) may be t...

The phase diagram of nuclear matter offers fascinating features for heavy ion physics and astrophysics when extended to strangeness and antimatter. We will discuss some regions of this phase diagram as strange matter at zero temperature, hypermatter at high densities and the antiworld at high densities and strangeness fraction. 1 Strange Matter and Hypermatter Relativistic heavy ion collisions ...

ne of the four real attributes of the necessary being is divine knowledge, which enjoys special significance. reviewing various views in defining knowledge and giving the rational arguments as well as narrated proofs to establish divine knowledge , the present paper deals in detail with the objects and the how of divine knowledge. among different things that are the objects of divine knowledge,...

The temperature evolution of the chiral condensates in a gas made of pions, kaons and etas is studied within the framework of SU(2) and SU(3) Chiral Perturbation Theory. We describe the temperature dependence of the quark condensates by using the meson meson scattering phase shifts in a second order virial expansion. We find that the SU(3) formalism yields an extrapolated melting temperature fo...

The work focuses attention on strange but nonchaotic behaviour of dynamic systems as a relatively new phenomenon distinct from the usual strange chaotic one. Several characterization techniques associated with Poincare sections, Lyapunov exponents, capacity and information dimensions are used. It is shown that based on a single time series it is virtually impossible to distinguish between stran...

Zombies are bodies without minds: creatures that are physically identical to actual human beings, but which have no conscious experience. Much of the consciousness literature concerns how threatening philosophical reflection on such creatures is to physicalism. There is not much attention given to the converse possibility, the possibility of minds without bodies, that is, creatures who are cons...

The Improvisational Theater Space is an interactive stage where human actors can perform accompanied by virtual actors. Virtual actors are modeled as animated \Media Creatures" that are behavior-based automous software agents. We used Artiical Life programming methods and behavior-based design to avoid rigid scripting of performers and media interaction. Media Creatures allow content to be acti...

BERRY III is a simulator for autonomous robots and artificial creatures. This report describes the various elements of the simulated environment and the implementation of the physical part of the simulator. The body, the sensor and motor systems of the simulated creatures are described in detail together with the algorithms used to model interaction between objects. These algorithms include cal...

In this study, we aim to evolving autonomous virtual creatures which have complex shapes in a complex environment. We implement a basic physics law and fluid influences with a virtual environment and evolve artificial creatures in plural environments (on the ground, in the water). Each model, which is evolved in a different environment, obtains an effective moving behavior in each environment (...
