Abstract Comorbid Alzheimer’s disease (AD) neuropathology is common in Lewy body disease (LBD); however, AD comorbidity in the prodromal phase of LBD remains unclear. This study investigated AD comorbidity in the prodromal and symptomatic phases of

There are some difficulties in a Monte-Carlo simulation when it is used for simulating a large-scale MIMO antenna. In a conventional Monte-Carlo simulation, the scatterers are arranged at regular intervals on a circle. The number of scatterers requir
