The expression of transforming growth factor alpha (TGFalpha), amphiregulin (AR) and cripto-1 (CR-1) was assessed by immunohistochemistry in 83 specimens (59 primary ovarian tumors and 24 extra-ovarian carcinomas) that were obtained from 68 ovarian carcinoma patients. Within the 59 primary tumors, 54 (92%) expressed immunoreactive TGFalpha, 45 (76%)(More)
This paper describes the high precision digital sun sensor under development at the University of Naples. The sensor determines the sun line orientation in the sensor frame from the measurement of the sun position on the focal plane. It exploits CMOS technology and an original optical head design with multiple apertures. This allows simultaneous multiple(More)
This paper presents a customized three-dimensional template matching technique for autonomous pose determination of uncooperative targets. This topic is relevant to advanced space applications, like active debris removal and on-orbit servicing. The proposed technique is model-based and produces estimates of the target pose without any prior pose(More)
An optical flow-based technique is proposed to estimate spacecraft angular velocity based on sequences of star-field images. It does not require star identification and can be thus used to also deliver angular rate information when attitude determination is not possible, as during platform de tumbling or slewing. Region-based optical flow calculation is(More)
Developmental stuttering is a disruption in normal speech fluency and rhythm. Developmental stuttering usually manifests between 6 and 9 years of age and may persist in adulthood. At present, the exact etiology of developmental stuttering is not fully clear. Besides, the dopaminergic neurological component is likely to have a causal role in the(More)
This paper focuses on a prototypical test system aimed at estimating field performance of integrated aircraft navigation systems. Assumed design requirements for the navigation system are cm-level positioning accuracy and absolute attitude estimation error in dynamic conditions of the order of 0.1° at most. Since performance estimation does not(More)
In male rats, pretreatment for 20 days with very low (0.5, 1%, v/v) but not with high (5, 10%, v/v) oral doses of ethanol delayed the initiation and reduced the duration of narcosis induced by an acute high intraperitoneal (i.p.) dose of the drug (3 g/kg in 25% saline solution). Furthermore, the treatment improved the acquisition of shuttle-box active(More)
