Abstract

Quantum coherence plays an important role in quantum resource theory, which is strongly related with entanglement. Similar to the entanglement evolution equation, we find the coherence evolution equation of quantum states through fully and strictly incoherent operation (FSIO) channels. In order to quantify the full coherence of qudit states, we define G-coherence and convex roof of G-coherence, and prove that the G-coherence is a strong coherence monotone and the convex roof of G-coherence is a coherence measure under FSIO, respectively. Furthermore, we prove a coherence evolution equation for arbitrary $d$-dimensional quantum pure and mixed states under FSIO channels, which generalizes the entanglement evolution equation for bipartite pure states. Our results will play an important role in the simplification of dynamical coherence measure., Comment: 9 pages, 4 figures

Abstract

Currently, research on the flavor components and their dynamic changes in roasted chicken with a special flavor is rare. In this study, a passion fruit-roasted chicken was prepared, its characteristic flavor components were profiled by flavoromics, and their evolution patterns and precursors were determined. The results showed that the characteristic flavor component with the highest contribution rate was ethyl butyrate (50.44%). In particular, some unique flavor compounds were identified compared with other roasted chicken products available. The main volatile flavor components in all stages of processing were alcohols, esters, and hydrocarbons, 15 to 30 min of roasting is an important stage for establishing the aroma system, and at the end, hydrocarbons were the main volatile compounds. During the 30-day storage period, the characteristic flavor components included ethyl butyrate, ethyl maltol, β-caryophyllene, and guaiacene. In conclusion, passion fruit-roasted chicken contained many characteristic flavor components, which were mainly formed within 15 to 30 min of roasting and were basically stable during the 30-day storage period. In a word, this work prepared a novel roasted chicken and revealed its mechanism of flavor formation at different baking stages and storage periods, which provided references for industrial production.

Abstract

Coherence plays an important role in quantum resource theory, which is strongly related with entanglement. Similar to the entanglement factorization law, we find the coherence factorization law of quantum states through fully and strictly incoherent operation (FSIO) channels. In order to quantify the full coherence of qudit states, we define G-coherence and convex roof of G-coherence, and prove that the G-coherence is a strong coherence monotone and the convex roof of G-coherence is a coherence measure under FSIO, respectively. Experimental verification of the coherence factorization law for qubits and qutrits under genuinely incoherent operations (GIOs) has been shown in [Photonics Research \textbf{10}, 2172 (2022)]. Actually, GIO is a special case of FSIO. We prove that coherence factorization law can be generalized under all possible FSIO channels for arbitrary qudit states., 7 pages, 1 figure

13. Optical Fiber Composite Winding for In Situ Thermal Monitoring of Transmitter Magnetic Mechanism in Long-Track DWPT Systems

Abstract

Thermal monitoring of the long-track transmitter (Tx) magnetic mechanism of an industrial dynamic wireless power transfer (DWPT) system is necessary for its reliable operation. This article proposes an optical fiber composite winding (OFCW) for in situ thermal monitoring of the long-track Tx mechanism. Multichannel optical fibers are compounded on the Tx winding wire, which forms a composite structure, to detect the internal thermal distribution of the whole long-track Tx with fast response and high spatial resolution. A simplified optimization method based on magnetic and temperature field distribution characteristics is then studied to obtain a specific OFCW layout for rapid hotspot measurement and application extensions. Finally, an OFCW-based scaled-down DWPT prototype is established, and the experimental results with accurate thermal monitoring under different operating states confirm the feasibility and effectiveness of the OFCW.

Abstract

2‐D modular wireless power transfer (WPT) system needs to have stable output when coil misalignment occurs. In order to improve the misalignment tolerance of the system coupling unit, this article proposes a magnetic coupling structure based on the LCC‐S compensation topology by combining a rectangular coil with two sets of mutually orthogonal solenoidal compensation coils. The rectangular coil is used to receive the vertical magnetic flux, and the two sets of compensating coils are used to receive the magnetic flux in the directions of X‐axis and Y‐axis on the horizontal plane, separately. The receiving side of the 2‐D wireless power transmission array cells cascaded half‐bridge rectifiers to connect each group of coils. This arrangement effectively compensates for the voltage drop of the rectangular coil caused by positional offset in any direction, so that the output voltage of the receiving side remains stable. The article firstly establishes the equivalent circuit model of the proposed design and deduces in detail the relationship equations between the output characteristics of the system and each influence factor. Secondly, the magnetic coupling structure is designed by finite element electromagnetic simulation software, and the total equivalent mutual inductance fluctuation of the proposed design is verified to be within 3.9% over the range of 2‐D transmission array cells. Finally, a 150 W experimental platform is built to verify the misaligment‐tolerant of the proposed design in the range of 2‐D transmission array cells. The experimental results show that the output voltage fluctuation of the proposed design within 4.27% at all directional offsets. Moreover, the stable output performance can be obtained in the case of vertical and rotational misalignment. [ABSTRACT FROM AUTHOR]

Abstract

Composite materials have potential applications in power systems because of their excellent electrical and mechanical characteristics. Composite towers can solve problems existing in the construction and operation of regional transmission lines. However, there are many problems that need to be solved before their large-scale practical application. Composite materials used for electric towers are synthesized with polyurethane resin and glass fiber, contributing to poor hydrophobicity and self-cleaning capacity as well as poor antifouling property. So hydrophobic coatings have been applied to the surface of materials in this paper. Electrical tests on the composite material samples, including wetting flashover test, pollution flashover test, and icing flashover test, were conducted to study the properties of hydrophobic coatings, which demonstrate that flashover voltage of hydrophobic coated composite samples is significantly improved. At present, the key technical problems that limit the large-scale application of composite towers are aging and degradation of mechanical properties. To test those two properties of composite towers and relevant composite materials, 5000-h multifactor artificial accelerating aging tests were carried out, which proved that the composite samples used for the tower and the composite tower itself have good aging resistance and mechanical properties. © 2017 Institute of Electrical Engineers of Japan.
