Time-resolved energy transfer from single chloride terminated nanocrystals to graphene
, 2014 We examine the time-resolved resonance energy transfer of excitons from single n-butyl amine-bound, chloride-terminated nanocrystals to two-dimensional graphene through time-correlated single photon counting. The radiative biexponential lifetime kinetics

A Hybrid System for Driver Assistance Using Computer Vision Methods
StandardsDriver fatigue and drowsiness are the causes of many road accidents. In this work, a low-cost hybrid system is proposed for determining driver fatigue level based on four metrics: last sleep quality, blinking rate, heart rate variation, and yawning.

Arthritis Care &Research, EarlyView.Objective The study aimed to identify symptom‐based predictors of dry eye disease (DED) signs in the Sjögren's International Collaborative Clinical Alliance (SICCA) cohort. Methods We performed a retrospective analysis examining 16 ocular symptoms (most graded 0–4) and artificial tear (AT) use (graded 0–3) as predictors of DED signs (abnormal ocular ...

Visualizing the logistic map with a microcontroller [PDF]
, 2011 The logistic map is one of the simplest nonlinear dynamical systems that clearly exhibit the route to chaos. In this paper, we explored the evolution of the logistic map using an open-source microcontroller connected to an array of light emitting diodes (
