The Sunyaev–Zel’dovich (SZ) effect is a powerful new tool for finding and studying clusters at high redshift, particularly in combination with their X-ray properties. In this paper we quantify the expected scaling relations between these properties using numerical simulations with various models for heating and cooling of the cluster gas. For a Non-radiative model, we find scaling relations in ...

Relations for possible local quasars are studied: the “mass-radius”, “density-mass”, and “radius-density” relations. These relations show clear fragmentation and which is due to the presence of parallel sequences of observations. The cause for this unusual fragmentation is the presence of a term depending on rgr/rq in each respective relation. It seems therefore that fragmentation in these rela...

The construct validity of maternal mind-mindedness (MM) was investigated in the context of its relations with children's later understanding of mind. MM measures were obtained from infant-mother (N = 52) interactions at 6 months, and from maternal interviews at 48 months. Children's understanding of mind was assessed using theory of mind (ToM) tasks at 45 and 48 months, and a stream of consciou...

Quentin Smith has argued that the new tenseless theory of time is faced with insurmountable problems and should be abandoned in favour of the tensed theory of time. Smith’s main argument attacks the fundamental premise of the tenseless theory: that tenseless truth conditions for tokens of tensed sentences adequately capture the meaning of tensed sentences. His position is that tenseless truth c...

1998-1999 school year poses the question of how the United States should change its foreign policy toward Russia. Although debate about foreign policy has been relegated to a back-seat compared to domestic issues by the American public, the academic community in international relations (IR) has been energized by the end of the Cold War. The Russia topic will provide a challenging opportunity fo...

The paper presents an analysis of the interpretation of recursive types as logical relations in the framework of iterative algebraic theories. This allows a smoother presentation of the underlying technique, and easier proofs of properties of the interpretation.
