We consider black strings in five dimensions and their description as a (4, 0) CFT. The CFT moduli space is described explicitly, including its subtle global structure. BPS conditions and global symmetries determine the spectrum of charged excitations, leading to an entropy formula for near-extreme black holes in four dimensions with arbitrary charge vector. In the BPS limit, this formula reduc...

We analyse the spectrum of perturbations of the de Sitter space on the one hand, while on the other hand we compute the location of the poles in the Conformal Field Theory (CFT) propagator at the border. The coincidence is striking, supporting a dS/CFT correspondence. We show that the spectrum of thermal excitations of the CFT at the past boundary I − together with that spectrum at the future b...

The aim of the present work was to estimate the possibility of improving the objectiveness of complement fixation test (CFT) in the diagnosis of dourine by using an ELISA microplate reader. The investigations were carried out on control positive and negative sera and 16 sera obtained for a reference examination. Six modifications of CFT performing and reading methods were compared (tube, microp...

We explore the superstring theory on AdS3 × S3 × T 4 in the framework given in [1]. We argue on the Hilbert space of “space-time CFT”, especially, construct a suitable vacuum of this CFT from the physical degrees of freedom of the superstring theory in bulk. We first construct explicitly it in the case of p = 1, and then present a proposal for the general cases of p > 1. After giving some compl...

Conformal field theory (CFT) with the central charge c=1 is important both in the field theory and in the condensed matter physics, since it has the continuous internal symmetry (U(1) or SU(2)) and a marginal operator, and it is an effective theory of many 1D quantum spin and 1D electron systems. So it is valuable to understand how the c=1 CFT models become unstable. In this paper we discuss an...

Children with fetal alcohol spectrum disorders (FASD) have significant social skills deficits. The efficacy of a child friendship training (CFT) versus a delayed treatment control (DTC) was assessed for 100 children ages 6 to 12 years with FASD. Children in the CFT showed clear evidence of improvement in their knowledge of appropriate social behavior, and according to parent report, CFT resulte...

Background Chlamydia pecorum is a globally significant livestock pathogen causing pathology and production losses. The on-farm infection and serological dynamics and the relevance of existing diagnostic tools for diagnosing C. pecorum in livestock remains poorly characterized. In this study, we characterized the antigen and antibody dynamics of this pathogen in a longitudinal study of prime lam...

The dS/CFT correspondence differs from its AdS/CFT counterpart in some ways, yet is strikingly similar to it in many others. For example, both involve CFTs defined on connected spaces (despite the fact that the conformal boundary of deSitter space is not connected), and both impose constraints on scalar masses (Strominger’s bound for deSitter, and the BreitenlohnerFreedman bound for Anti-deSitt...

It is shown that quantum-induced (inflationary) brane Universe occurs in the bulk 5d AdS black hole in accordance with AdS/CFT correspondence. Brane stress tensor is induced by quantum effects of dual CFT and brane crosses the horizon of AdS black hole. Quantum-corrected Hubble constant, Hawking temperature and entropy are found on the brane (and at the horizon). The similarity between CFT entr...
