摘要:
A photonic radiation detection device includes a collimator, a detector, and localization means for determining information relative to the localization of a photon interaction with the detector material. In at least one previously selected acquisition configuration, a degree of pixelation in the detection plane is greater than 1 and a collimator-detector distance (C) is greater than one tenth of the septal height (h) of the collimator where the septal height is a maximum dimension of the collimator in a direction orthogonal to the frontal detection plane. In one instance, the septal wall thickness (e) is one of about 0.1 or less than about 0.1 of the channel width (w). In another instance, the collimator-detector distance is greater than h/(2(w/e−1)). A dimensioning method includes, for at least one given spatial frequency, calculating and comparing merit indicator values for different acquisition configurations of a structural model of the detection device.

A method for producing a plurality of chips each comprising an individualisation region, each chip comprising at least: a first and a second level of the electrical tracks, and an interconnections level comprising vias. The method includes producing on the dielectric layer covering the first level a mask having openings located in line with the electrical tracks and making the dielectric layer accessible. The method includes producing, in a region of the chip comprising the individualisation region, patterns conformed so that: first openings of the hard mask are not masked by the patterns, and second openings of the hard mask are masked by the patterns. The method includes producing via openings in the dielectric layer in line solely with the first openings. The method further includes filling in the via openings with an electrically conductive material, and producing the second level of the electrical tracks on the vias.

摘要:
Using chemical proteomics with a potent unique irreversible inhibitor, inventors found that major brain tubulin carboxypeptidase (TCP) is a complex of vasohibin-1 (VASH1) with the Small Vasohibin-Binding Protein (SVBP). VASH1 and its homologue vasohibin-2 (VASH2), when complexed with SVBP, exhibit robust and specific Tyr/Phe carboxypeptidase activity on microtubules. Accordingly inventors are the first to identify the enzymatic activity of vasohibin and vasohibin/SVBP complex. Knock down of vasohibins or SVBP in cultured neurons results in a marked reduction of tyrosinated α-tubulin levels and onset of severe differentiation defects. Furthermore, knock down of vasohibins disrupts neuronal migration in developing mouse neocortex. These results establish vasohibin/SVBP complexes as TCP enzymes. Accordingly, the present invention relates methods and pharmaceutical compositions for treating tubulin carboxypeptidases (TCP) associated diseases such as neurological disorders and cardiovascular diseases with an inhibitor of activity or expression of Vasohibin or Vasohibin/SVBP complex.
