Precisely distinguishing between hyperplastic and adenomatous polyps and normal human colonic mucosa at the cellular level is of great medical significance. In this work, multiphoton laser scanning microscopy (MPLSM) was used to obtain the high-contrast i
Highly conducting ZnO:Al (AZO) films are normally prepared through substrate heating and post-annealing in reducing atmosphere, which is deleterious to maintain the high transparency of films and the overall so-lar cell performance. Here we fabricate AZO
To increase the photoelectronic conversion efficiency of the single discharge tube and to meet the requirements of the laser cutting system, optimization of the discharge tube structure and gas flow field is necessary. We present a computational fluid dyn
为提高反辐射导弹近炸引信目标识别能力, 提出了一种融合导引头信息与激光近炸引信信息的目标识别方法。在分析导引头与引信信息的一致性与冲突基础上, 应用D-S证据理论综合利用导引头与引信信息判定导弹从目标上方掠过或落于目标前方; 对于导弹掠过目标的情况, 采用Dempster规则融合导引头与激光近炸引信测得的目标信息, 以正确识别出目标雷达。研究结果表明, 基于D-S理论的制导与引信信息融合方法, 可以有效地判别弹目交会情况并以较高的概率识别出目标。
This paper exploits an optical large multiple input multiple output (MIMO) system. We first establish the non-reciprocity compensation correction factor to solve the channel non-reciprocity problem. Then we propose an antenna selection algorithm with the
We propose new types of hybrid plasmonic waveguides for low-threshold nanolaser applications. Modal properties and lasing threshold under different geometric shapes and parameters are investigated and -analyzed by the finite element method, aiming to real
本文报道利用激光感生荧光测量方法在纯氩直流空心阴极放电(HCD)中探测到Ar~ 4p-4s态间存在粒子数反转,给出了实验数据,并作了相应解释.
The achromatic subdiffraction lens with large numerical aperture (NA) is of significant importance in optical imaging, photolithography, spectroscopy, and nanophotonics. However, most of the previous research on subdiffraction lenses has been restricted b
