BACKGROUND
Patients with cancer experience many stressors placing them at risk for posttraumatic stress disorder (PTSD) symptoms, yet little is known about factors associated with PTSD symptoms in this population. This study explored relationships among patients' PTSD symptoms, physical and psychological symptom burden, and risk for hospital readmissions.
METHODS
We prospectively enrolled patients...
BACKGROUND
Although hospitalized patients with advanced cancer have a low chance of surviving cardiopulmonary resuscitation (CPR), the processes by which they change their code status from full code to do not resuscitate (DNR) are unknown.
METHODS
We conducted a mixed‐methods study on a prospective cohort of hospitalized patients with advanced cancer. Two physicians used a consensus‐driven medical...
BACKGROUND
Patients with advanced cancer often experience frequent and prolonged hospitalizations; however, the factors associated with greater health care utilization have not been described. We sought to investigate the relation between patients' physical and psychological symptom burden and health care utilization.
METHODS
We enrolled patients with advanced cancer and unplanned hospitalizations...
This paper presents a recursive nonideality compensation method for Voltage Source Inverter (VSI) controlled by Predictive Current Control (PCC) in the field of electrical drives. An accurate mathematical model of the effects of VSI nonlinearities, such as dead time and control delay, is here reported including the magnitude loss and the ripple distortion. For every sampling interval, the exact voltage...
This paper deals with a compensation technique for non-linear behaviour of single phase modular multi-level power converter, feeding electric vehicle fast charging station with split integrated energy storage system. The proposed method calculates the voltage compensation on the basis of the error between the reference and the real currents. It allows highly improving the harmonic content of the grid...
The adoption of the smart and sustainable charging infrastructures for electric vehicles (EVs) represents a key-point to accelerate the electro-mobility uptake. This paper presents an optimal power flow management for a smart charging micro-grid that minimizes the cost and reduces the impact on the grid of EVs requests. This goal is achieved by means of an optimal integration and control of renewable...
This paper deals with the optimal sizing and power flow control for grid-connected multi-source power converter system for EV charging infrastructure with integrated energy storage system. The sizing of the power conversion system is based on cost-benefit analysis which takes into account several factors to define the e-mobility scenario and different topologies of power conversion units. The proposed...
An interleaving modulation for parallel inverters based photovoltaic (PV) systems is presented in this paper. It allows increasing the conversion efficiency with respect to centralized inverter solution, in whatever operating condition. The experimental results fully confirm the validity and feasibility of the proposed system.
A novel power converter configuration for high power grid-connected photovoltaic (PV) systems is presented in this paper. It allows increasing the conversion efficiency with respect to a classical solution, based on centralized inverter, in whatever operating condition. In particular, the improvement of efficiency is due to both optimal power sharing algorithm and suitable interleaving modulation...
A novel multi-inverter power converter for double motor electric vehicles is presented in this paper. Thanks to a supercapacitor auxiliary storage unit and to a suitable control algorithm, the proposed setup allows to optimize the vehicle performances in terms of traction control and power flow.
