    Abstract A crucial issue in quantum communication tasks is characterizing how quantum resources can be quantified and distributed over many parties. Consequently, entanglement has been explored extensively. However, there are few genuine multipartite entanglement measures and whether it is monogamous is so far unknown. In this work, we explore the complete monogamy of genuine multipartite entanglement measure (GMEM) for which, at first, we investigate a framework for unified/complete GMEM according to the unified/complete multipartite entanglement measure we proposed in 2020. We find a way of inducing unified/complete GMEM from any given unified/complete multipartite entanglement measure. It is shown that any unified GMEM is completely monogamous, and any complete GMEM that is induced by given complete multipartite entanglement measure is completely monogamous. In addition, the previous GMEMs are checked under this framework. It turns out that the genuinely multipartite concurrence is not as good of a candidate as GMEM.

    Yu, Guo

    Abstract The efficacy of active noise control technology in mitigating urban noise, particularly in relation to low-frequency components, has been well-established. In the realm of traditional academic research, adaptive algorithms, such as the filtered reference least mean square method, are extensively employed to achieve real-time noise reduction in many applications. Nevertheless, the utilization of this technology in commercial goods is often hindered by its significant computing complexity and inherent instability. In this particular scenario, the adoption of the fixed-filter strategy emerges as a viable alternative for addressing these challenges, albeit with a potential trade-off in terms of noise reduction efficacy. This work aims to conduct a theoretical investigation into the synchronization error of the digital Active Noise Control (ANC) system. Keywords: Fixed-filter, Active noise control, Multichannel active noise control.

    Abstract In order to understand the progress and frontier in the application of BSA(bulked segregant analysis) method in crop breeding and to reflect objectively the contribution of different countries, institutions and researchers in this field at home and abroad, this study analyzed 2111 items in the WOS (Web of Science) database from 2000 to 2023 and 446 items in the CNKI (China National through Knowledge Infrastructure) database from 2003 to 2023, regarding the researches of the application of BSA in crop breeding, basing on bibliometric analysis methods using CiteSpace software including keyword co-occurrence analysis, highlight word analysis, keyword clustering analysis, clustering timeline analysis and author co-citation. The results showed that there was an consistent increasing trend in the publication number of the application of BSA in crop breeding both in the domestic and foreign journals year by year. Ranking of the top countries according to the number of publications was China, the United States and India. The Huazhong Agricultural University displayed the highest number of publications in the CNKI database, while the Chinese Academy of Agricultural Sciences was found to have the highest number of publications in the WOS database. The published articles related to the application of BSA in crop breeding abroad mainly focused on the disciplines such as plant science, agronomy, horticulture and genetics, while those in China mainly concentrated on such disciplines as plant science, plant protection, horticulture and biology. The top three authors in terms of influence in the field of appling BSA in crop breeding were Michelmore RW, Kosambi DD and Li H, while Michelmore RW, Lander ES and Li H had closer cooperations with other authors. The top three crops relating to the studies of BSA were rice(Oryza sativa), soybean(Glycine max), corn(Zea mays L.) with the hot spot traits of disease resistance and plant height domestically. The top three crops involving the studies of BSA were rice, Arabidopsis thaliana and wheat(Triticum aestivum L.) with hot spot traits of disease resistance abroad. Up to now, BSA was mainly used to localize and functionally verify the candidate genes linking target traits and the mutated genes in crops in the domestical documents, while the foreign published studies based on BSA were mainly focused on the fine mapping and functional verification of target trait genes aiming at the revelation of genetic mechanisms in crops. Research frontier analysis indicated that rice, peanuts(Arachis hypogaea L.), upland cotton(Gossypium hirsutum L.) would be the main objects of studies concerning application of BSA in crop breeding with the hot topics of crop mutants and crop metabolites in the future.

    Abstract Estimating river flood risks under climate change is challenging, largely due to the interacting and combined influences of various flood-generating drivers. However, a more detailed quantitative analysis of such compounding effects and the implications of their interplay remains underexplored on a large scale. Here, we use explainable machine learning to disentangle compounding effects between drivers and quantify their importance for different flood magnitudes across thousands of catchments worldwide. Our findings demonstrate the ubiquity of compounding effects in many floods. Their importance often increases with flood magnitude, but the strength of this increase varies on the basis of catchment conditions. Traditional flood analysis might underestimate extreme flood hazards in catchments where the contribution of compounding effects strongly varies with flood magnitude. Overall, our study highlights the need to carefully incorporate compounding effects in flood risk assessment to improve estimates of extreme floods.

    Abstract Nitrilases represent a distinct class of enzymes that play a pivotal role in catalyzing the hydrolysis of nitrile compounds, leading to the formation of corresponding carboxylic acids. These enzymatic entities have garnered significant attention across a spectrum of industries, encompassing pharmaceuticals, agrochemicals, and fine chemicals. Moreover, their significance has been accentuated by mounting environmental pressures, propelling them into the forefront of biodegradation and bioremediation endeavors. Nevertheless, the natural nitrilases exhibit intrinsic limitations such as low thermal stability, narrow substrate selectivity, and inadaptability to varying environmental conditions. In the past decade, substantial efforts have been made in elucidating the structural underpinnings and catalytic mechanisms of nitrilase, providing basis for engineering of nitrilases. Significant breakthroughs have been made in the regulation of nitrilases with ideal catalytic properties and application of the enzymes for industrial productions. This review endeavors to provide a comprehensive discourse and summary of recent research advancements related to nitrilases, with a particular emphasis on the elucidation of the structural attributes, catalytic mechanisms, catalytic characteristics, and strategies for improving catalytic performance of nitrilases. Moreover, the exploration extends to the domain of process engineering and the multifarious applications of nitrilases. Furthermore, the future development trend of nitrilases is prospected, providing important guidance for research and application in the related fields.

    Abstract Background and aim: Low-carbon technology innovation(L-CTI) is an essential way to realize the socio-economic transition to a low-carbon model. However, relatively few studies have been conducted on the calculation of low-carbon technology innovation efficiency(L-CTIE) and the identification of factors influencing it. The study intends to assess the L-CTIE of new energy enterprises(L-CTI-NEEs) and to analyze its influencing factors, so as to further improve the L-CTIE capability. Methods: Using the panel data of new energy enterprises(NEEs) in 2010-2020, DEA(BCC)-Malmquist-Tobit method is constructed to static and dynamic evaluate the L-CTIE of new energy enterprises(L-CTIE-NEEs), and analyze its influencing factors with triple helix theory. Results: During the study period, the L-CTIE among NEEs was quite different, and the Malmquist index change trend had phased characteristics. From the perspective of factors influencing innovation efficiency, technology integration capacity of enterprises, support intensity of government and cooperation scale of government-enterprises-universities & research institutions play a crucial part in promoting the EEFCH, PECH and SECH of L-CTIE-NEEs, while resource conversion capacity of universities & research institutions only promotes PECH. Conclusion: According to the research results, a triple helix model of L-CTI-NEEs is constructed to enhance its L-CTIE level.

    Abstract Community residents’ support is one of the key factors affecting the development of tourist destinations. A clear understanding of influencing factors and internal transmission mechanisms in community residents’ support for tourism can lend to a theoretical basis and reference for tourism management departments to formulate relevant policies. It is therefore conducive to the rapid recovery and sustainable development of tourism amidst the intermittent outbreaks of COVID-19 pandemic. Taking Guilin as the site for a case study, this study examined the effect of local residents’ perceptions of risks due to the COVID-19 pandemic, benefits of tourism and residents’ participation in it, government trust, and support for tourism. In particular, the intermediary role of residents’ tourism participation and the moderating role of government trust has been explored. A total of 383 residents in Guilin City were selected as the sample for hierarchical regression analysis. The results showed that perceived risks had a significant negative impact on support for tourism, but no significant impact on resident participation. Tourism’s perceived benefits had a significant positive impact on both support for and participation in tourism, and residents’ participation played a partial mediating role in the relationship between perceived benefits of and support for tourism. Government trust played a significant moderating role in the relationship between tourism’s perceived benefits and residents’ participation, between perceived benefits and support for tourism, and between residents’ participation in and support for tourism.

    Abstract The purpose of this study was to investigate the effect of Yupingfeng granules, a well-known traditional Chinese medication, combined with glucocorticoids on eosinophil (EOS) number and inflammatory factors in nasal secretions of patients with allergic rhinitis (AR). 76 patients with AR were randomly divided into controls (nasal inhaled corticosteroids alone) and experimental group (combined with Yupingfeng granules orally). The efficacy, symptoms, number of EOS and levels of inflammatory factors in nasal secretions were compared between the two groups after 2 months of treatment. The results showed that in the experimental group (94.73%, 0.48 ± 0.25 points), the effective rate of treatment was obviously higher and the physical sign score was clearly lower compared with controls (81.57%, 0.97 ± 0.36 points); the EOS count in the experimental group was clearly less than that in the controls; the tumor necrosis factor-α (TNF-α) (0.76 ± 0.44 ng/mL), interleukin-6 (IL-6) (11.83 ± 3.72 pg/mL), and interleukin-8 (IL-8) (17.45 ± 6.53 pg/mL) levels were evidently lower in the experimental group than in the controls (1.48 ± 0.72 ng/mL, 14.62 ± 5.19 pg/mL, 22.86 ± 9.35 pg/mL) (P < 0.05). In summary, compared with nasal inhalation of glucocorticoids alone, combined with oral administration of Yupingfeng granules, it can more significantly improve the symptoms of nasal obstruction and rhinorrhea in AR patients, reduce nasal mucosal edema, reduce the number of EOS in nasal secretions, and reduce the level of inflammatory factors, which is of positive significance for the clinical treatment of AR patients.
