A symmetrical semi-ring polarization converter based on slotted frequency selective surface (SFSS) is presented in this paper. The proposed SFSS is a free metallic screen without supported media, and the corresponding formulas are provided to calculate its frequency response. Good agreements can be observed between the simulated and calculated results. The phase difference between TE and TM components...
Selecting points using min-max strategy can guarantee uniformity of Pareto. But shortcomings are missing effective solutions and poor solutions being selected. By the analysis of choosing points with the min-max strategy and reasonable fitness metric, we propose a new evolutionary method choosing weights on points (point-to-weight). A large number of multi-objective optimization functions have been...
The concept of generalized concatenated quantum codes (GCQC) provides a systematic way for constructing good quantum codes from short component codes. We introduce a stabilizer formalism for GCQCs, which is achieved by defining quantum coset codes. This formalism offers a new perspective for GCQCs and enables us to derive a lower bound on the code distance of stabilizer GCQCs from component codes...
The science of acupuncture and moxibustion is an important component of Traditional Chinese Medicine (TCM) with a long history. Although there are a number of different acupuncture manipulations, the relationship between the evoked electrical signal time series and manipulations is rarely investigated. In this work, the authors choose the twirling manipulation to accomplish the biotic experiment in...
The effect mechanism of acupuncture is closely related to neural system. When stimulated by different acupuncture manipulations, the neural system can evoke different electrical signals, because the excited receptors and nerve fiber types are different. As to nervous system, information encoding is in the time mode and frequency mode of spike trains. Power spectrum analysis, histogram statistic and...
Since reform and opening up, ocean economy in China keeps a growth speed higher than that of national economy in the corresponding period. Zhejiang Province is much richer in ocean resources than inland regions. However, due to the short history, ocean economy of Zhejiang Province is still in less developed conditions. Currently, the development gaps of Zhejiang ocean economy are mainly ocean science...
As it started relatively late, the development of Zhejiang ocean economy is relatively backward. To develop Zhejiang ocean industrial economy, we must further enrich and promote the idea of ocean economy, increase the concentration on ocean development from “industry concept” to “economy concept”, and regroup the basic work idea from a strategic viewpoint, in accordance with the requirements of scientific...
