BACKGROUND AND OBJECTIVE Counterfactual thinking (CFT) refers to the generation of mental simulations of alternatives to past events, actions and outcomes. CFT is a pervasive cognitive feature in every-day life and is closely related to decision-making, planning and problem-solving - all of which are cognitive processes linked to unimpaired frontal lobe functioning. Huntington's Disease (HD) is...

The complement fixation test (CFT) and indirect hemolysis test (IHLT) were applied to sera collected from 60 cattle challenged with Brucella abortus 544. Of the 60 cattle, 48 were vaccinated with either B. abortus 19 or B. abortus 45/20 as calves or as adults. The remaining 12 cattle were not vaccinated. Of the 27 sera from cattle found to be infected, 9 showed aberrant reactions to the CFT. Th...

An S-matrix is defined for anti-de Sitter space by constructing “in” and “out” states that asymptote to the timelike boundary. An analog of the LSZ formula shows that this boundary S-matrix is given directly by correlation functions in the boundary conformal theory. This provides a key entry in the AdS to CFT dictionary. † Email address: [email protected] The conjectured AdS/CFT corresp...

The prescription of the AdS/CFT correspondence is refined by using a regularization procedure, which makes it possible to calculate the divergent local terms in the CFT two-point function. We present the procedure for the example of the scalar field. It has been stated in most papers on this subject that the correspondence between a fields theory on anti-de Sitter space (AdS) and a conformal fi...

We realize the two dimensional anti-de Sitter (AdS2) space as a KaluzaKlein reduction of the AdS3 space in the framework of the discrete light cone quantization (DLCQ). Introducing DLCQ coordinates which interpolate the original (unboosted) coordinates and the light cone coordinates, we discuss that AdS2/CFT correspondence can be deduced from the AdS3/CFT . In particular, we elaborate on the de...

BACKGROUND We present the electrophilic synthesis of [18F]2β-carbomethoxy-3β-(4-fluoro)tropane [[18F]CFT] and the pharmacological specificity and selectivity of [18F]CFT for monoamine transporters in the brain and peripheral organs of rats. The human radiation dose is extrapolated from the animal data. METHODS [18F]CFT was synthesized by electrophilic fluorination of a stannylated precursor b...

BACKGROUND AND PURPOSE The empirical use of antibiotic therapy is widely accepted for patients with fever and neutropenia during cancer chemotherapy. The use of intravenous monotherapy with broad-spectrum antibiotics in patients at high risk for complications is an appropriate alternative. However, few data are available for pediatric patients. The aim of this study was to compare the efficacy ...

The DØ Level 2 (L2)trigger is a subsystem of the overall DØ trigger [1] which has the responsibility of reducing the event rate from 10 KHz to 1 KHz, while introducing less than 5% deadtime. The system is organized as a number of preprocessors and a global processor. Each preprocessor digests information from a single detector system and produces a condensed list of the objects. The global proc...
