Computer simulation of the electronic noise of solid-state detectors
No full textIn this paper we propose a mathematical procedure to computer simulate the electronic noise of ionizing-radiation spectrometers as observed at the output of the preamplifier or of the anti-aliasing filter, just in front of the ADC. Examples are given for the case of segmented HPGe (High Purity Germanium) detectors. The method makes use of the fractional calculus basics. A software procedure provides the noisy waveform as a function of the fundamental electrical-physical parameters of the system, including: detector capacitance, detector leakage current, feedback resistor, 1/f-noise coefficient of the input transistor, temperature of the preamplifier input devices
Architettura, governo e burocrazia in una capitale barocca. La "Zona di Comando di Torino" e il piano di Filippo Juvarra del 1730
No full textGiovanni Gabrieli and the New Venetian School (Malipiero, Maderna, Nono)
No full textThe present essay examines the reception of Giovanni Gabrieli in the writings of Gian Francesco Malipiero, Bruno Maderna and Luigi Nono, together with accessible documentation regarding their compositional, editorial, concert and recording activities. Contrary to well consolidated opinions on the New Venetian School, the approaches of these three composers reflect neither linear nor “genealogical” patterns but, on the contrary, their own personal itineraries
TGFbeta potentiates TNFalpha –induced tissue factor expression in human endothelial cells
No full textRobust real-time monitoring of human task advancement for collaborative robotics applications
No full textA crucial problem in human-robot collaboration is to achieve seamless coordination among the agents. Robots have to adapt to human behaviour, which is highly uncertain. In fact, humans can perform each task in many ways and with different speeds, occasional errors and short pauses. This paper offers a robust method to monitor the advancement of the current human activity in real-time in order to predict its duration. The algorithm learns online templates of new variants of the task and uses them as references for a Dynamic Time Warping-based algorithm. The proposed strategy has been tested within a realistic assembly task. Results show its ability to give accurate predictions also in case of peculiar variants, such as those associated with errors
A murine model of cerebral cavernous malformations with acute hemorrhage
No full textCavernomas are multi-lumen and blood-filled vascular malformations which form in the brain and the spinal cord. They lead to hemorrhage, epileptic seizures, neurological deficits, and paresthesia. An effective medical treatment is still lacking, and the available murine models for cavernomas have several limitations for preclinical studies. These include disease phenotypes that differ from human diseases, such as restriction of the lesions to the cerebellum, and absence of acute hemorrhage. Additional limitations of current murine models include rapid development of lesions, which are lethal before the first month of age. Here, we have characterized a murine model that recapitulates features of the human disease: lesions develop after weaning throughout the entire CNS, including the spinal cord, and undergo acute hemorrhage. This provides a preclinical model to develop new drugs for treatment of acute hemorrhage in the brain and spinal cord, as an unmet medical emergency for patients with cavernomas
