We report on measurements of hadronic and leptonic cross sections and leptonic forwardbackward asymmetries performed with the L3 detector in the years 1993–95. A total luminosity of 103 pb−1 was collected at centre-of-mass energies √ s ≈ mZ and √s ≈ mZ±1.8 GeV which corresponds to 2.5 million hadronic and 245 thousand leptonic events selected. These data(More)
Gamma detectors based on monolithic scintillator blocks coupled to APDs matrices have proved to be a good alternative to pixelated ones for PET scanners. They provide comparable spatial resolution, improve the sensitivity and make easier the mechanical design of the system. In this study we evaluate by means of Geant4-based simulations the possibility of(More)
<sup>68</sup>Ga is one of the non-conventional nuclides that are being used in preclinical imaging. One disadvantage of <sup>68</sup>Ga versus <sup>18</sup>F is its larger positron range, which deteriorates the effective spatial resolution and the overall image quality. In this work we present a performance evaluation of the ARGUS small-animal positron(More)
During 12 months of follow-up in a randomized double-blind controlled field study, a killed whole-promastigote vaccine cocktail plus bacille Calmette-Guérin (BCG) adjuvant significantly reduced the incidence of cutaneous leishmaniasis (CL) in Ecuadorian children, compared with BCG alone. To determine how much longer protection might continue, the study was(More)
The BrainPET scanner is a magnetically-compatible human PET insert based on APDs and LYSO:Ce monolithic scintillators, which is currently under development at CIEMAT, intended for the operation inside magnetic resonance imaging (MRI) equipment. An ASIC called VATA241 was specifically designed for the BrainPET project. This ASIC includes a constant fraction(More)
We have analyzed the performance of a PET demonstrator formed by two sectors of four monolithic detector blocks placed face-to-face. Both front-end and read-out electronics have been evaluated by means of coincidence measurements using a rotating <sup>22</sup>Na source placed at the center of the sectors in order to emulate the behavior of a complete full(More)
