To describe the prevalence and incidence density of hospital-acquired unavoidable pressure sores among patients aged ≥65 years admitted to acute medical units. A secondary analysis of longitudinal study data collected in 2012 and 2013 from 12 acute medical units located in 12 Italian hospitals was performed. Unavoidable pressure ulcers were defined as those that occurred in haemodynamically uns...
Particle track reconstruction capabilities of the silicon tracking detector system have been studied. As the multiple Coulomb scattering (MCS) induces unavoidable uncertainties on the coordinate measurement, the corresponding error estimates and the associated correlations have been used to find the best track fit parameters and their errors. Finally it permits to find the proper particle chara...
In this paper, we propose and validate a framework for visual navigation with collision avoidance for a wheeled mobile robot. Visual navigation consists of following a path, represented as an ordered set of key images, which have been acquired by an on-board camera in a teaching phase. While following such path, the robot is able to avoid obstacles which were not present during teaching, and wh...
Abstract Contracting cosmologies are known to be flawed with a shear instability, where the contribution from anisotropic stress overall energy density grows as $$a^{-6}$$ a - 6 , scale factor. Classically, whether or not this bec...
