We studied both numerically and experimentally electromagnetic behaviors of a bilayered metal helical structure in the microwave-frequency. Two resonances are found in the transmission spectrum of ...the circularly polarized wave which has the same handedness with the helices. The resonance frequencies are almost independent on the distance between the two layers. In addition, the center frequency of full width at half-maximum (FWHM) in the transmission spectrum is approximately inversely proportional to the distance between the two layers.
In the domain of supervised scene flow estimation, the process of manual labeling is both time-intensive and financially demanding. This paper introduces SSFlowNet, a semi-supervised approach for ...scene flow estimation, that utilizes a blend of labeled and unlabeled data, optimizing the balance between the cost of labeling and the precision of model training. SSFlowNet stands out through its innovative use of pseudo-labels, mainly reducing the dependency on extensively labeled datasets while maintaining high model accuracy. The core of our model is its emphasis on the intricate geometric structures of point clouds, both locally and globally, coupled with a novel spatial memory feature. This feature is adept at learning the geometric relationships between points over sequential time frames. By identifying similarities between labeled and unlabeled points, SSFlowNet dynamically constructs a correlation matrix to evaluate scene flow dependencies at individual point level. Furthermore, the integration of a flow consistency module within SSFlowNet enhances its capability to consistently estimate flow, an essential aspect for analyzing dynamic scenes. Empirical results demonstrate that SSFlowNet surpasses existing methods in pseudo-label generation and shows adaptability across varying data volumes. Moreover, our semi-supervised training technique yields promising outcomes even with different smaller ratio labeled data, marking a substantial advancement in the field of scene flow estimation.
To compare compound staining methods showing leprotic bacillus, elastic fibre and cell nucleus etc. in skin biopsy tissue.
A compound staining dye composed of Ziehl-Neelsen Phenol Fuchsin, Victoria ...blue, iodine green and Martius yellow were used in paraffin-embedding skin biopsy tissue.
Leprotic bacilli showed red; cell nuclei, light green; cell cytoplasm, colorless; elastic fibres around tuberculoid nodules, blue; and essential substances, light yellow in skin biopsy tissue.
Because the color was single in Ziehl-Neelsen staining method, its contrast was poor. The ZN-VB-IG compound staining method may show leprotic bacilli, elastic fibres and cell nuclei etc. distinctly. Therefore, this is a reliable and nice color contrast compound staining method.
