TL;DR: Wang et al. as discussed by the authors performed a multicenter, population-based longitudinal cohort study including 9075 low-risk singleton pregnant women and found that fetal growth velocity was determined by calculating the first derivative of fetal size curves and used logistic regression to estimate the association between fetal growth velocities in the bottom 10th percentile and adverse perinatal outcomes.

TL;DR: In this article, the influence of energy transfer up-conversion (ETU) on diode-end-pumped actively Q-switched Tm,Ho:YLF lasers is investigated by the rate equation analysis.

TL;DR: In this paper, an all-optical switch using a Mach-Zehnder racetrack resonator has been proposed to realize nonlinear optical switching between steady ON/OFF states at about 200 microwatt low threshold over a wide wavelength range.

TL;DR: The quinoa yellow wine is prepared according to the following methods: performing impurity removal and pulverization on quinoa rice and corn kernels, weighing pulverized quinoa Rice and corn residues according to a mass ratio of (0.4 to 1.4) to(0.6 to 1) as mentioned in this paper.

TL;DR: In this article , a compact, orthogonally polarized, gain-switched a-cut Ho:LuLiF4 laser with intra-cavity pumping by a self-Q-switching Tm:YAP laser is demonstrated for the first time.
