Anxiety and its risk factors among non-Japanese residents living in Japan undergoing COVID-19 situation: A cross-sectional survey.

Introduction: In the context of collective efforts taken in Japan to control the spread of COVID-19, the state of emergency and social distancing have caused a negative impact on the mental health of all residents, including foreign communities in Japan. This study aimed to evaluate the level of anxiety and its associated factors among non-Japanese residents residing in Japan during the COVID-19 pandemic.

Methods: A web-based survey in 13 languages was conducted among non-Japanese residents living in Japan during the COVID-19 situation.

Tuning the fluorescence of Dy via the structure of borophosphate glasses.

The optical characteristics of Dy-doped phosphate and borophosphate glasses with different divalent network modifiers prepared by melt-quenching are studied. The glass sets (A) with a molar composition of 40MO-60PO and (B) with a molar composition of 40MO-20BO-40 PO are investigated, both with M = (Zn, Mg, Ca, Sr, or Ba) and all doped with 0.1 mol% DyO.
