We discuss the role of singletons and logarithmic operators in AdS 3 string theory in the context of AdS 3 /CF T 2 correspondence.

In this article we prove that a semialgebraic map $$\pi :M\rightarrow N$$ is branched covering if and only its associated spectral covering. addition, such has neat behavior with respect to the branching locus, ramification set index. A crucial fact preceding result characterization of prime ideals whose fibers under previous are singletons.

The theory of evidence (ToE) [16] extends classical probability theory through the notion of belief function (b.f.), a mathematical entity which independently assigns probability values to sets of possibilities rather than single events. A belief function b : 2 → [0, 1] on a finite set (“frame”) Θ has the form b(A) = ∑ B⊆A mb(B) where mb : 2 Θ → [0, 1], is called “basic probability assignment” ...

Previous research has shown that in visual search static singletons have the ability to capture attention (Theeuwes, 1991a, 1992). The present study investigated whether these singletons also have the ability to capture the eyes. Participants had to make an eye movement and respond manually to a shape singleton while a color singleton was present. When participants searched for a unique shape w...

When we look around, only a part of the visual signals arriving at our retinae at each moment in time is selected for in-depth processing. This form of selectivity is called visual attention. Visual attention has many different purposes. Selection can gate access of information to perception (Scharlau, 2002), memory (Duncan & Humphreys, 1989), or motor control (Allport, 1989). Corresponding to ...

We give a simple derivation of the conformal blocks of the singleton sector of compactifications of IIB string theory on spacetimes of the form X5×Y5 with Y5 compact, while X5 has as conformal boundary an arbitrary 4-manifold M4. We retain the second-derivative terms in the action for the B,C fields and thus the analysis is not purely topological. The unit-normalized conformal blocks agree exac...

We discuss the role of singletons and logarithmic operators in AdS 3 string theory in the context of AdS 3 /CF T 2 correspondence.

In this study, we determined the effect of maternal undernutrition in the periconceptional (PCUN: ~80 days before to 6 days after conception) and preimplantation (PIUN: 0-6 days after conception) periods on the mRNA and protein abundance of key factors regulating myogenesis and protein synthesis, and on the relationship between the abundance of these factors and specific microRNA expression in ...

OBJECTIVE To estimate the prevalence of major birth defects diagnosed by 6 years of age in all births and terminations of pregnancy for fetal anomaly conceived by assisted reproductive technology (when this included intracytoplasmic sperm injection and in vitro fertilization [IVF]) and the remainder of nonassisted reproductive technology-conceived children born in Western Australia from 1994 to...

DNA-based species delimitation may be compromised by limited sampling effort and species rarity, including "singleton" representatives of species, which hampers estimates of intra- versus interspecies evolutionary processes. In a case study of southern African chafers (beetles in the family Scarabaeidae), many species and subclades were poorly represented and 48.5% of species were singletons. U...
