Diabetic retinopathy (DR) is one of the most common diabetic complications and remains the leading cause of vision loss among adults. C1q/TNF-related protein 3 (CTRP3) is a member of CTRP family that has been found to be involved in the progression of diabetes mellitus and diabetic complications. Ho...

A new channel estimation method is proposed based on fast orthogonal frequency-division multiplexing (FOFDM), which can be effectively used in our experiment based on intensity modulation and direct detection. In this experiment, the FOFDM subcarrier channel spacing is half of the symbol rate. The s...
