Subjects with peripheral arterial disease (PAD) of the lower limbs are at high risk for cardiovascular and cerebrovascular events and the prevalence of coronary artery disease in such patients is elevated. Recent studies have shown that regular use of cardiovascular medications, such as therapeutic and preventive agents for PAD patients, seems to be(More)
In this work we compute the effective thermal conductivity of porous Si by means of the phonon Boltz-mann transport equation. Simulations of heat transport across aligned square pores reveal that the thermal conductivity can be decreased either by increasing the pore size or decreasing the pore spacing. Furthermore, by including the surface specularity(More)
We develop a computational framework, based on the Boltzmann transport equation (BTE), with the ability to compute thermal transport in nanostructured materials of any geometry using, as the only input, the bulk cumulative thermal conductivity. The main advantage of our method is twofold. First, while the scattering times and dispersion curves are unknown(More)
In this work we present a multiscale method to model self-heating effects in nanostructured devices. While the heating is modeled within the drift-diffusion approximation, the heat dissipation is computed by means of a concurrent coupling between a Phonon Boltzmann Transport Equation (PBTE) based method and the Fourier model. We develop the way to connect(More)
Due to the downscaling of semiconductor device dimensions and the emergence of new devices based on nanostructures, CNTs and molecules, the classical device simulation approach based on semi-classical transport theories needs to be extended towards a quantum mechanical description. We present a simulation environment designed for multiscale and multiphysics(More)
OBJECTIVE To describe the emergency and delayed treatment of patients with pelvic fracture urethral injuries (PFUI) presenting to an Italian high-volume centre. PATIENTS AND METHODS In a retrospective, observational study we evaluated the spectrum of PFUI and posterior urethroplasty in an Italian high-volume centre, from 1980 to 2013. Patients requiring(More)

A fully selfconsistent, coupled electro-thermo-mechanical model for nitride-based devices is presented and applied to a high-power AlGaN/GaN High Electron Mobility Transistor (HEMT). The influence of converse piezoelectric effect, thermal stress and of the selfconsistent coupling on the static device characteristics and on the stress distribution in the(More)
—In this paper we review the progress made in the development of the new multiscale/multiphysics simulator TIBERCAD, able to combine on equal footing macroscopic and microscopic scales of device models. The tool is not limited to conventional devices but has been also applied to systems were transport of excitons or ions are important for the correct(More)
