It is necessary to know the distribution of the Chinese eye's aberrations in clinical environment to guide high-resolution retinal imaging system design for large Chinese population application. We collected the monochromatic wave aberration of 332 healt
The changes of holographic characteristics of photopolymer induced by temperature are studied experimentally. The results show that the exposure sensitivity increases with the increase of temperature. The maximum diffraction efficiency and the final maxim
Continuous wave operation of a semiconductor laser diode based on five stacks of InAs quantum dots (QDs) embedded within strained InGaAs quantum wells as an active region is demonstrated. At room temperature, 355-mW output power at ground state of 1.33-1.
Exact interaction mechanism between Bax and Bcl-XL, two key Bcl-2 family proteins, is an interesting and controversial issue. Partial acceptor photobleaching-based quantitative fluorescence resonance energy transfer (FRET) measurement, PbFRET, is a widely
We propose a linear mapping relationship between the polarization of the fundamental mode and the cylindrical vector (CV) modes on the first-order Poincaré sphere (FOPS) in fiber. The new method is based on the four-dimensional complex Jones matrices in t
基于串联(concat)操作的特征融合方法仅仅融合了相邻尺度的特征,并没有充分利用来自其他尺度的输出特征。并且,串联操作只是在通道维度上将不同尺度的特征连接,不能反映不同通道间特征的相关性和重要性。针对这些问题,提出了一种基于注意力机制的特征融合算法。该算法利用注意力机制来融合不同尺度的特征,通过对每个通道的特征进行权重分配来学习不同通道间特征的相关性。将基于注意力机制的特征融合算法与YOLO V
