Exploring health literacy and its associated factors among Palestinian university students: a cross-sectional study.

Health literacy plays an important role in personal and community health. Since university is a turning point when young adults begin to take responsibility for their own health, understanding university students' health literacy levels is crucial. To this end, we aimed to explore health literacy and its associated factors among Palestinian university students.

Characterization of semiconductor-laser phase noise and estimation of bit-error rate performance with low-speed offline digital coherent receivers.

We develop a systematic method for characterizing semiconductor-laser phase noise, using a low-speed offline digital coherent receiver. The field spectrum, the FM-noise spectrum, and the phase-error variance measured with such a receiver can completely describe phase-noise characteristics of lasers under test. The sampling rate of the digital coherent receiver should be much higher than the phase-fluctuation speed.
