There exists a need for the design of light emitting diode (LED) luminaires which can deliver both visual and Collections non-visual benefits of light to humans.In this work, we introduce an optimization approach based on spectral shaping for a minimalistic and practical design of a circadian-tunable multi-channel luminaire which also outputs white

Abstract Objective Training models are required to impart surgical skills, like wound closure techniques, prior to practice in patients.In an ideal case, the tissue characteristics of the 3-Wheel Rollators model are close to those of humans, easy to create and of low cost.Methods Here, we describe a model to train students in wound closure techniqu
