A 222 nm all-solid-state far-ultraviolet C (UVC) pulse laser system based on an optical parametric oscillator (OPO) and second-harmonic generation (SHG) using β-Ba2BO4 (BBO) crystals was demonstrated. Pumped by a Nd:Y3Al5O12 with repetition rate of 100 Hz at 355 nm, the maximum signal energy 1.22 mJ 444 wavelength obtained from BBO-OPO system, corresponding to conversion efficiency 27.9%. The output 164.9 µJ successfully achieved, SHG 16.2%. Moreover, tunable UVC light 210 252.5 achieved.

ABSTRACT The ability to rapidly recognize basic facial emotions (e.g. fear) is crucial for social interactions and adaptive functioning. To date, the origin of facial-emotion-recognition remains equivocal. Using a classical twin design in humans, we found clear dissection low high spatial frequencies (LSF HSF) emotion perception: whereas genetic factors contributed individual variation LSF processing, HSF processing largely shaped by environmental effects. Furthermore, content genetically...

Human activities have considerably increased nitrogen intake into waterways, resulting in the deterioration of water quality. The state surface requires special consideration light crisis caused by pollution. In this study, natural abundance stable isotope (δ 15N) is measured and sampled sediments compared with total dissolved (DN) four main Chinese tributaries Hun River upper reach, including Dasuhe, Beisanjia, Beikouqian, Nanzamu tributaries. Results show that for Dasuhe Nankouqian...
