Active metasurfaces have recently attracted more attention since they can make the light manipulation be versatile and real-time. Metasurfaces-based holography possesses the advantages of high spatial resolution and enormous information capacity for applications in optical displays and encryption. In this work, a tunable polarization multiplexing holographic metasurface controlled by an external magnetic field is proposed. The elaborately designed nanoantennas are arranged on the magneto-optical intermediate layer, which is placed on the metallic reflecting layer. Since the non-diagonal elements of the dielectric tensor of the magneto-optical material become non-zero values once the external magnetic field is applied,the differential absorption for the left and right circularly polarized light can be generated. Meanwhile, the amplitude and phase can be flexibly modulated by changing the sizes of the nanoantennas. Based on this, the dynamic multichannel holographic display of metasurface in the linear and circular polarization channels is realized via magnetic control, and it can provide enhanced security for optical information storage. This work paves the way for the realization of magnetically controllable phase modulation, which is promising in dynamic wavefront control and optical information encryption.

Objectives: To explore the relationship between adiponectin (APN) and bone mineral density in this Zhuang ethnic group, thus providing a basis underpinning the prevention and treatment of osteoporosis (OP). Methods: Zhuang women over 50 years old in Guangxi Zhuang Autonomous Region were included in the study. The broadband ultrasound attenuation (BUA) was adopted as the reference to calculate the T value. Quantitative ultrasonic bone density was measured on the right. Body composition measuring instrument was used to measure weight, fat, and muscle mass. Plasma APN level was detected by ELISA and blood lipids were detected by enzymatic method. Results: Plasma APN level was found with significant differences in the normal bone mineral density group, bone mineral density reduction group, and osteoporosis group (P β = −0.176, P = 0.001) when the partial correlation coefficient of APN is −0.210. Elevated APN was an independent risk factor for bone mineral density reduction (OR = 1.191, 95%CI: 1.004 - 1.407, P = 0.04) and OP (OR = 1.1337, 95%CI: 1.137 - 1.572, P Conclusion: Increased APN in postmenopausal women of Zhuang is an independent risk factor for OP. The application of APN in the OP screening and prevention of middle-aged and ageing Zhuang women still needs further research.

本文使用LSTM模型对日、周、月三个时间尺度下的产品需求量进行预测.结果表明,采用日尺度模型时,由于时间序列过长,模型无法达到收敛状态,在构建模型时应缩短时间序列;而使用周尺度模型时,损失函数逐渐收敛于横轴,训练效果较为显著;月尺度模型仍有提升空间,需要进一步训练以完全收敛.不同时间尺度会对预测精度产生影响,很大或很小的时间尺度可能导致预测误差增加.

相位是光场信息的重要组成部分。在光学显微成像领域,大部分生物细胞对光的吸收较弱,传统的亮场显微无法准确地表征细胞的结构特征,因此相位成像成为非标记细胞观测的重要方法。经典的相衬显微镜基于干涉成像原理,通常需要大块的折射棱镜或者复杂的成像系统,因而系统臃肿,易受环境扰动。超表面是一种特征尺寸在纳米或微米量级的光学元件,具有强大的光场调控能力,超表面集成在显微系统中可以实现方向无关、单摄式的定量相位成像,具有小型、轻便、易集成等优点。本综述回顾经典的相位成像技术原理,详细介绍基于剪切干涉、相位衬比和强度传输方程等3类超表面的相位成像技术原理,比较不同技术的优缺点和适用场景,指出超表面在相位成像领域面临的挑战,并对未来发展趋势进行展望。
