The risk for all the manifestations of atherosclerotic disease is increased in patients affected by type 2 diabetes mellitus. The aim of the present work was to evaluate the prevalence of coronary heart disease (CHD) in a well-characterized middle-aged and elderly Italian diabetic population. The population studied included 3862 subjects, i.e. all the… (More)
This paper describes the design and performance of a low-noise and high-speed optical sensor that provides two output signals in quadrature from the simultaneous detection of four phase-shifted interferograms. The sensor employs four high-speed photodiodes and high-speed, low-noise transimpedance amplifiers. The optical and electronic design was optimized… (More)
We present a novel design for large area, wideband, polymer piezoelectric sensor with low capacitance. The large area allows better spatial resolution in applications such as photoacoustic tomography and the reduced capacitance eases the design of fast transimpedance amplifiers. The metalized piezoelectric polymer thin film is segmented into N sections,… (More)
In a study on the prevalence of cardiovascular autonomic neuropathy and retinopathy in a group of 57 diabetic subjects, an increased prevalence of these complications related to the duration of diabetes has been found.
The modeling of bubbles initiated by laser-irradiated nanoparticles is of interest for many applications. There is at present no comprehensive physical picture for all the stages of the process. We present an alternative approach with a key assumption: the vapor bubble evolves adjacent to the nanoparticle. To take into account the irreversible evolution,… (More)
This paper presents a model suitable to design and characterize broadband thin film sensors based on piezoelectric polymers. The aim is to describe adequately the sensor behavior, with a reasonable number of parameters and based on well-known physical equations. The mechanical variables are described by an acoustic transmission line. The electrical behavior… (More)
