Association between all aspects of dietary diversity and risk of depressive symptoms in US adults.

The impact of dietary diversity on depressive symptoms remains one-sided. We aim to explore the associations between all aspects of dietary diversity and the risk of depressive symptoms in US adults and their dose-response relationships. We selected 16 820 adults from the National Health and Nutrition Examination Survey (NHANES) from 2013 to 2018.

Direct deflection radius measurement of flexible PET substrates by using an optical interferometry.

The deflection radius is essential in determining residual stress estimations in flexible electronics. However, the literature provides only indirect methods for obtaining a deflection radius. In this study, we present a measurement methodology for directly measuring the deflection radius of a polyethylene terephthalate (PET) substrate (a popular substrate of flexible electronics) by using an optical interferometer.
