Pe bza optimizarii detectorului fotodioda cu avalansa din sistemul EmiScopeTM utilizat pentru rezolvarea temporala a fotonilor, am realizat reducerea cu un factor mai mare de 2.5 a timpului de achizitie a semnalului emis în infrarosu de un tranzisttorCMOS. Efectul nedorit al pulsuirlor de zgomot generate de fotodioda la durate aleatorii fata de semnalul detectat a fost redus prin utilizarea înt...

conclusion both techniques provided quantitatively consistent results of in vivo velocity vector fields in right internal carotid artery (rca). pc mri represented a good estimation of main flow patterns inside the vasculature, which seems to be acceptable for clinical use. however, limitations of each technique should be considered while interpreting results. subjects and methods mr imaging was...

In this article we consider n gluon color ordered, planar amplitudes in N = 4 super Yang Mills at strong ’t Hooft coupling. These amplitudes are approximated by classical surfaces in AdS5 space. We compute the value of the amplitude for a particular kinematic configuration for a large number of gluons and find that the result disagrees with a recent guess for the exact value of the amplitude. O...

A visual search has been made of four fields using United Kingdom 1.2m Schmidt Objective Prism plates with a reciprocal dispersion of 1 180 A/mm at HP. Such plate material is ideally suited to searches for emission-line galaxies. We present a catalogue of 53 emission-line objects, which comprises 45 galaxies, where individual HI1 regions are resolved in 16 bright galaxies; 8 are emission li...

This paper addresses the problem of selecting measurement data types suitable for image reconstruction in optical tomography. The principal problem is the necessity to simultaneously reconstruct both the absorption and scatter distribution within an object. This can lead to ambiguities between these two parameters, and result in cross-talk and image artefact. A single-perturbation test problem ...
