This study determines how untreated recycled concrete aggregates (URA), thermally treated recycled concrete aggregates (TRA), and recycled concrete aggregates developed through an integrated thermomechanical treatment process (TmRA) perform in concrete relative to each other. A concrete composed of 100% recycled aggregates (RCA) with Portland pozzolana cement has been successfully developed in the present study. The compressive strength, split tensile strength, flexural strength, fracture energy, and modulus of elasticity of TmRC is observed higher than URC by 18.62%, 8.20%, 40.72%, 24.18%, and 54.99%, and those TRC by 7.54%, 28.57%, 29.78%, 24.12%, and 34.35%, respectively. The split tensile strength, flexural strength, fracture energy, and modulus of elasticity of these concretes are strongly correlated with their compressive strength. TmRC material properties match NAC, standard requirements, and reported values closely. URC and TRC chloride-ion penetrations are around 3.51- and 2.42-times greater than TmRC. Among these concretes, only TmRC meets corrosion protection requirements like NAC. The abrasion resistance of TmRC is observed 52.03% greater than URC and 43.07% greater than that of TRC. TmRC has substantially lower sorptivity compared to URC and TRC and is close to NAC. TmRC has around 32.65% and 16.67% less weight loss in drying than URC and TRC, respectively. URC and TRC have around 1.99- and 1.82-times less abrasion resistance than TmRC. An optimal reduced adhered-mortar volume, the minimized porosity and microcracks, dense and uniform surface texture, strengthened interfacial transition zones leads the performance of TmRA superior to URA and TRA, and close to or superior to parent aggregates.

Inorganic CsPbI3 perovskite has great potential to fabricate deep‐red light‐emitting diodes (LEDs) owing to excellent color purity, thermal stability, and carrier mobility. However, fabricating high‐quality CsPbI3 thin films for high‐performance LEDs remains challenging. While it is demonstrated that hydrogen bonds between organic ammonium cations and molecule additives can lead to high‐quality organic–inorganic hybrid perovskite films, this method cannot be applied to CsPbI3 thin films due to the absence of hydrogen bonds between Cs+ ions and additives. In this study, an amorphous complex‐seed‐crystal growth process to fabricate high‐quality γ‐CsPbI3 cuboid crystallite thin films, is reported. During the initial annealing, the metastable intermediates formed crystal nucleate seeds and transformed into amorphous complex intermediates, maintaining stability at an elevated temperature for perovskite crystallization. With prolonged annealing, the amorphous complex around the nucleate seeds gradually converts to γ‐CsPbI3 perovskite, enabling us to fabricate CsPbI3 thin films with high crystallinity and orientation. The resulting deep‐red LEDs exhibit a peak external quantum efficiency (EQE) of 16.5% and a high maximum luminance of 3158 cd m−2. Moreover, the devices show significantly suppressed efficiency roll‐off, maintaining an EQE of 14.8% even under a high current density of 500 mA cm−2. [ABSTRACT FROM AUTHOR]

Nanosized ZSM-5 zeolite with high-quality is highly desired in industrial application. This paper reports an approach of rapid synthesis of this type zeolite, being realized by crystallizing gels with the Si/Al atomic ratio of 12.5–80 at 170 ℃ for 12 h under assistance of guanidinoacetic acid (GAA). As a result, the zeolite obtained from the synthesis possesses little crystal size (120–220 nm), high-quality and good monodispersity. Being associated with the superior morphology and structure, the zeolite displayed not only longer one-pass catalytic lifetime but also much higher regeneration stability in methanol-to-olefin reaction, comparing with the zeolite synthesized without GAA addition.

Background The urban community health service centers in China have developed for nearly 20 years, but there is a lack of systematic research on their development, progress made, and existing problems. Objective To propose suggestions for the high-quality development of urban community health services centers in China by analyzing their development situation. Methods In October 2022, 50 community health service centers were selected from 13 provinces in the eastern, central and western regions by convenience sampling method. A self-developed research questionnaire based on the key core indicators for the assessment of urban community health services centers included two parts of basic data and evaluation content. Basic data included jurisdictional area, number of employees, number of outpatient visits, etc; the evaluation content included 4 gradeⅠindicators (institutional configuration, service function, service mode, and service support), 13 GradeⅡindicators and 33 GradeⅢindicators. The data of year 2006 (or the first year of the hospital's establishment and data) and 2021 were compared, and the survey results were reported in through "sojump". Results (1) Basic data: the number of community health service centers established before 2006 were 24 (accounting for 48.00%), and 26 after 2006 (accounting for 52.00%) ; comparing the year of 2006 or the first year of establishment, and the year of 2021, the number of employees was 67.00 (40.00, 101.00) and 94.00 (62.00, 162.00) respectively; the number of outpatient visits was 39 324.00 (22 620.00, 118 384.00) and 106 259.00 (44 999.00, 225 851.00) respectively; the total score of the questionnaire was 36.50 (28.13, 46.00) and 69.00 (56.38, 76.00), respectively. (2) The median scores of Grade I indicators institutional configuration, service mode and service function in 2021 were all higher than those in 2006 or the first year of establishment. The relative scoring rate of Grade I indicators in 2021, institutional configuration was 77.27% (25.50/33.00), service mode was 61.84% (23.50/38.00), service function was 76.92% (10.00/13.00), service support was 47.37% (9.00/19.00). The median score of structure area in the institutional configuration indicators was 0; among the service function indicators, the relative scoring rate of the diagnosis and treatment of common and chronic diseases in the community, and the inpatient service content were all 100.00%; the relative scoring rate of inpatient bed utilization rate was 25.00% (1.00/4.00). (3) Score of GradeⅡ、Ⅲ evaluation indicators of service function, service mode, and service support: The median score of public health items in service function increased from 2.00 points in 2006 or the first year of establishment to 9.50 points in 2021. The differences were statistically significant (P

With the rapid development of the digital economy and digital technologies, the significance of digital transformation for high-quality enterprise development has been growing. Anchored in the framework of the Resource-Based View, this study employs a meta-analytic approach to systematically, quantitatively analyze 40 empirical studies published between 2010 and 2022. The aims are to synthesize and identify the impact mechanisms of digital transformation on high-quality enterprise development, while also further examining the moderating effects of heterogeneity. The findings reveal that digital transformation exerts a significantly positive influence on high-quality enterprise development through three mechanisms: factors related to innovation, factors linked to enterprise performance, and factors associated with capital market performance. Notably, irrespective of the degree of heterogeneity, both the primary effects of digital transformation on high-quality enterprise development and the moderating effects of various impact mechanisms are statistically significant. The results underscore the importance of digital transformation in driving high-quality enterprise development and offer valuable insights for relevant decision makers. [ABSTRACT FROM AUTHOR]

High-quality cardiopulmonary resuscitation (CPR) and training are important for successful revival during out-of-hospital cardiac arrest (OHCA). However, existing training faces challenges in quantifying each aspect. This study aimed to explore the possibility of using a three-dimensional motion capture system to accurately and effectively assess CPR operations, particularly about the non-quantified arm postures, and analyze the relationship among them to guide students to improve their performance. We used a motion capture system (Mars series, Nokov, China) to collect compression data about five cycles, recording dynamic data of each marker point in three-dimensional space following time and calculating depth and arm angles. Most unstably deviated to some extent from the standard, especially for the untrained students. Five data sets for each parameter per individual all revealed statistically significant differences (p < 0.05). The correlation between Angle 1′ and Angle 2′ for trained (rs = 0.203, p < 0.05) and untrained students (rs = −0.581, p < 0.01) showed a difference. Their performance still needed improvement. When conducting assessments, we should focus on not only the overall performance but also each compression. This study provides a new perspective for quantifying compression parameters, and future efforts should continue to incorporate new parameters and analyze the relationship among them.

High-quality cardiopulmonary resuscitation (CPR) is important for successful revival. This test aimed to accurately and effectively assess parameters in CPR operations, particularly focusing on the non-quantified arm posture, to assist instructors in guiding students to enhance the quality of their performance. We used motion capture system (Mars series, Nokov, China) to collect compression data from four trained students about five rounds of CPR, recording dynamic data of each marker in three-dimensional space following time. Using the processed data, we calculated compression depth, frequency, and arm angles. Their performance still needed improvement, and there were variations in data within individuals. This suggests that when instructors conduct assessments, they should focus on not only the overall performance but also each compression. This experiment provides a new perspective for quantifying compression parameters, and future efforts should continue to optimize and incorporate new parameters for assessment.

The direct epitaxial growth of graphene on semi‐insulating SiC presents significant potential for a variety of technologically important applications, including next‐generation electronics, photonics, and quantum metrology. However, this approach also poses a competitive disadvantage in terms of quality and cost, primarily due to the uncontrollable and time‐consuming nature of the annealing process. Herein, a thermal shock annealing (TSA) method is reported that enables kinetics‐controlled epitaxial growth of graphene on SiC within 10 s, which efficiently fulfills the requirements for producing high‐quality, few‐layer, and low‐cost graphene on SiC. The epitaxial graphene (EG) grown on both β‐SiC nanoparticles (SiC@EG NPs) and centimeter‐scale α‐SiC wafer (EG/SiC) exhibits mono‐ or bi‐layer features with negligible structural defects. Moreover, the findings indicate that the TSA method can efficiently mitigate the persistent issue of step bunching conundrum and improve the flatness of EG/SiC. As an application demonstration, the significant enhancement of surface‐enhanced infrared absorption (SEIRA) by SiC@EG NPs is exhibited. The graphene plasmon arising on SiC@EG NPs enables SEIRA detection sensitivity of up to a monolayer of p‐nitrobenzenethiol (p‐NTP). Consequently, the precise regulation and comprehensive comprehension of TSA afford an exceedingly desirable approach to produce cost‐effective, high‐quality EG growth on SiC for diverse emerging application scenarios.

[Display omitted] To facilitate the transition of laboratory research to industrial applications, it is critical to establish a reliable protocol for the mass synthesis of high-quality graphene. Here, we present an efficient electrochemical intercalation-based exfoliation approach utilizing alternating current that allows for the production of sub-kilogram quantities of graphene. This strategy involves repeatedly intercalating foreign anions and cations into the interlayer gaps of dual-graphite electrodes, accelerating the graphite expansion process and maximizing the exfoliation efficiency of both electrodes while inhibiting excessive anodic oxidation. The exfoliation process leads to high-yield graphene nanosheets (92 %, primarily 1–3 layers) with minimal structural deterioration (I D /I G ratio of 0.05), high purity (2.1 at% oxygen), and outstanding electrical property (7.28 × 104 S m−1). Notably, our scaled-up manufacturing technique produces a record-breaking throughput of 135 g h−1, improving on the best-reported exfoliation efficiency with direct current by 35%. Furthermore, the as-made graphene demonstrates a large reversible capacity of 102 mF cm−2 for flexible supercapacitors, with robust cyclability with 99.5% after 10,000 cycles, excellent mechanical flexibility, and exceptional serial integration for adjustable voltage output. The efficient and scalable method presents a significant advancement in the large-scale manufacture of graphene, with potential for widespread industrial applications. [ABSTRACT FROM AUTHOR]

Balanced hypergraph partitioning is an NP-hard problem with many applications, e.g., optimizing communication in distributed data placement problems. The goal is to place all nodes across k different blocks of bounded size, such that hyperedges span as few parts as possible. This problem is well-studied in sequential and distributed settings, but not in shared-memory. We close this gap by devising efficient and scalable shared-memory algorithms for all components employed in the best sequential solvers without compromises with regards to solution quality. This work presents the scalable and high-quality hypergraph partitioning framework Mt-KaHyPar. Its most important components are parallel improvement algorithms based on the FM algorithm and maximum flows, as well as a parallel clustering algorithm for coarsening – which are used in a multilevel scheme with log (n) levels. As additional components, we parallelize the n-level partitioning scheme, devise a deterministic version of our algorithm, and present optimizations for plain graphs. We evaluate our solver on more than 800 graphs and hypergraphs, and compare it with 25 different algorithms from the literature. Our fastest configuration outperforms almost all existing hypergraph partitioners with regards to both solution quality and running time. Our highest-quality configuration achieves the same solution quality as the best sequential partitioner KaHyPar , while being an order of magnitude faster with ten threads. Thus, two of our configurations occupy all fronts of the Pareto curve for hypergraph partitioning. Furthermore, our solvers exhibit good speedups, e.g., 29.6x in the geometric mean on 64 cores (deterministic), 22.3x (log (n)-level), and 25.9x (n-level). [ABSTRACT FROM AUTHOR]

In today’s world, high-quality translated tourism promotional materials (TPMs) play a leading role in developing business sectors in general and the tourism sector in particular because TPMs are the most often used forms of media targeting actual tourists and other audiences. This study explored the perceptions of novice and experienced translators about the role of high-quality translated TPMs in promoting the tourism industry in Saudi Arabia. Fifty novice and experienced translators in Saudi Arabia participated in this study. Data gathering comprised quantitative data. The findings of the study revealed that a lot of participants (57.00%) had positive perceptions toward the role played by high-quality translated TPMs in promoting the tourism industry in Saudi Arabia. The findings also demonstrated that many of the respondents (60.85%) perceive that the main challenge in the translation of TPMs is culture-specific items that may be comparatively prevalent to the native population but unfamiliar to people outside that certain community.

AbstractThis paper introduces a highly efficient approach for progressive image secret sharing through the Discrete Hartley Transform (DHT), offering distinct advantages over existing methods. Leveraging DHT in the color domain, our approach achieves progressive sharing of color images while maintaining robustness and minimal visual impact. By optimizing quantization table selection, our method focuses on maximizing image recovery fidelity. Our extensive experiments showcase the efficacy of our proposed method, highlighting its potential for secure image sharing and superior image quality enabled by the real-number DHT transformation. Notably, our approach demonstrates strong security robustness and high-quality image reconstruction through histogram analysis. Objective assessment values of [Formula: see text] (PSNR), [Formula: see text] (NCC), [Formula: see text] (NAE), and [Formula: see text] (SSIM) underscore the superiority of our method. These results, coupled with its unique contributions and key factors, position our work as a promising solution in the field of image security and distribution, motivating further exploration and inspiring related research endeavors.

Green buildings have entered the stage of high-quality development, with a strong tendency towards healthy, low- carbon and intelligent building. The inevitable requirement of high-quality development is to rationally design "green building +" projects such as healthy buildings, low-carbon buildings and intelligent buildings on the basis of green buildings. The connotation of high-quality green building was elucidated and the design method of high quality green building was proposed. In the case study of residential project in Shandong Luneng Lingxiu City, the design methodology was introduced, which integrates green building, healthy building, low-carbon building and intelligent building, in order to provide reference for the development of high-quality green buildings.

The oxidative stability of extra virgin olive oil (EVOO) depends on its composition, primarily, phenolic compounds and tocopherols, which are strong antioxidants, but also carotenoids, squalene, and fatty acids contribute. The aim of this study was to evaluate the effect of malaxation conditions and olive storage on the composition of 'Corbella' EVOO produced in an industrial mill to determine which parameters and compounds could give more stable oils. Although a longer malaxation time at a higher temperature and olive storage had a negative effect on the content of α-tocopherol, squalene, flavonoids, lignans, phenolic acids, and phenolic alcohols, the antioxidant capacity and oxidative stability of the oil were improved because of an increase in the concentration of oleacein (56–71%) and oleocanthal (42–67%). Therefore, these two secoiridoids could be crucial for better stability and a longer shelf life of EVOOs, and their enhancement should be promoted. A synergistic effect between secoiridoids and carotenoids could also contribute to EVOO stability. Additionally, 'Corbella' cultivar seems to be a promising candidate for the production of EVOOs with a high oleic/linoleic ratio. These findings signify a notable advancement and hold substantial utility and significance in addressing and enhancing EVOO stability. [ABSTRACT FROM AUTHOR]

High-quality development has become the theme of agricultural modernization development, and high-quality agricultural development cannot be separated from digital empowerment. This paper studies the value, dilemma and practical path of digital economy enabling high-quality agricultural development. It is found that digital economy enables high-quality agricultural development with the value of stimulating the endogenous power of farmers through collaborative sharing effect, breaking the boundaries of time and space, optimizing the structure of rural human capital, and promoting the integration and symbiosis of rural industries. There are difficulties such as shortage of human resources in digital agriculture, insufficient capital investment and technical support for digital transformation, and widespread dispersion of agricultural operation. The practice path is to build a professional digital agriculture talent team, strengthen capital investment, promote scientific research and innovation, improve the top-level design, and formulate product standards.

The ocean plays a crucial role in human society's survival and development. While China's marine economy has grown rapidly in recent years, it has also led to serious problems inhibiting ecosystem sustainability. This paper proposes high-quality development of the marine economy and combines the improved entropy value method, fuzzy hierarchical analysis method (FAHP), and data envelopment analysis (DEA) method to establish a quadratic relative evaluation model. A two-layer comprehensive index framework with 19 indicators is built to measure various aspects of the marine economy, including innovation, coordination, green, openness, and sharing. Empirical analysis conducted on 11 coastal provinces in China using data mainly collected from the Chinese Statistical Yearbook reveals significant spatial patchiness in the high-quality development level of the marine economy. This discrepancy is largely due to differences in geographical locations, resources, and government policies. The study analyzes four benchmark provinces of high-quality development and summarizes their experiences. The paper concludes by providing suggestions and implications to support government decision-making. [ABSTRACT FROM AUTHOR]

The scientific community believes that high-quality, bulk layered, semiconducting single crystals are crucial for producing two-dimensional (2D) nanosheets. This has a significant impact on current cutting-edge science in the development of next-generation electrical and optoelectronic devices. To meet this ever-increasing demand, efforts have been made to manufacture high-quality SnS2 single crystals utilizing low-cost CVT (chemical vapor transportation) technology, which allows for large-scale crystal production. Based on the chemical reaction that occurs throughout the CVT process, a viable mechanism for SnS2 growth is postulated in this paper. Optical, XRD with Le Bail fitting, TEM, and SEM are used to validate the quality, phase, gross structural/microstructural analyses, and morphology of SnS2 single crystals. Furthermore, Raman, TXRF, XPS, UV–Vis, and PL spectroscopy are used to corroborate the quality of the SnS2 single crystals, as well as the proposed energy level diagram for indirect transition in the bulk SnS2 single crystals. As a result, the suggested method provides a cost-effective method for growing high-quality SnS2 single crystals, which could lead to a new alternative resource for producing 2D SnS2 nanosheets, which are in great demand for designing next-generation optoelectronic and quantum devices.

What are the features of high-quality online courses in higher education? In this scoping review, we explore peer-reviewed scholarship related to the features of online learning in postsecondary contexts. We searched ERIC (EBSCO), Education Research Complete, and SocINDEX with Fulltext to retrieve peer-reviewed literature from 2010-2022 pertaining to features of online learning in higher education. Two reviewers independently conducted the initial title and abstract screening (n = 1,574), full text review (n = 483), and data extraction of the included articles (n = 38). Using thematic content analysis to explore the data extracted from each article, we found that the literature predominately included scholarship related to quality online course design, instructor facilitation in online courses, quality assessment of online courses, and student engagement in online courses. The breadth of these themes included a multiplicity of strategies and approaches to consider when designing online learning experiences. We recommend that administrators, faculty members, and instructors responsible for designing online courses and programs for postsecondary contexts continue to incorporate these considerations to promote high-quality and consistent online offerings. We conclude the review by presenting four high-level considerations to guide these discussions. [ABSTRACT FROM AUTHOR]

During recent decades, the complexation of organic ligands toward several metal ions of s-p and d-block has been applied as a plan to enhance its antioxidant performance. Due to their wide range of beneficial impacts, coordination compounds are widely used in industries, specifically in the medicinal and pharmaceutical fields. The activity is generally improved by chelation consequently knowing that the characteristics of both ligands and metals can lead to the development of greatly active compounds. Chelation compounds are a substitute for using the traditional synthetic antioxidants, because metal chelates present benefits, including a variety in geometry, oxidation states, and coordination number, that assist and favor the redox methods associated with antioxidant action. As well as understanding the best studied anti-oxidative assets of these compounds, coordination compounds are involved in the free radical scavenging process and protecting human organisms from the opposing effects of these radicals. The antioxidant ability can be assessed by various interrelated systems. The methodological modification offers the most knowledge on the antioxidant property of metal chelates. Colorimetric techniques are the most used, though electron paramagnetic resonance (EPR) is an alternative for metallic compounds, since color does not affect the results. Information about systems, with their benefits, and restrictions, permits a dependable valuation of the antioxidant performance of coordination compounds, as well as assisting application in various states wherever antioxidant drugs are required, such as in food protection, appropriate good-packaged foods, dietary supplements, and others. Because of the new exhaustive analysis of organic ligands, it has become a separate field of research in chemistry. The present investigation will be respected for providing a foundation for the antioxidant properties of organic ligands, future tests on organic ligands, and building high-quality antioxidative compounds.

To promote the sustainable development of early childhood education (ECE) in undeveloped rural areas of China, it is vital to guarantee high-quality equity for all children from disadvantaged backgrounds. Focusing on analyzing the efficacy of the Chinese governments' policy support to promote quality and equity, the study constructs a tripartite evolutionary game model of ECE providers in undeveloped rural areas, local governments, and central government, and correlates the governments' financial investment with the regulation and supervision in ECE as strategy combination via a reward-punishment mechanism. Through the evolution process of "change-adjustment-convergence" of behavioral decisions, each party seeks optimization to achieve the ideal stable equilibrium state. The numerical simulation is used to verify the dynamic evolutionary process. The simulation results presented the governments' subsidies and reward, regulation, and supervision have a substantive effect on the improvement of quality and equity. Consequently, the governments should strengthen the regulation and supervision of rural ECE, formulate a more reasonable reward and punishment mechanism, and adjust and optimize the policies and measures to improve the efficiency of educational funding. This study can provide reference value for the optimization of relevant policies and the practical operation of new policy-making. [ABSTRACT FROM AUTHOR]

The development of China's manufacturing industry is still facing the challenge of regional imbalance. To solve the problem of development imbalance, it is necessary to realize regional development. First, we must analyze the development characteristics of different regions. To this end, we consider the requirements of the new development era and design an evaluation index system for the high-quality development level of the manufacturing industry from the dimensions of innovation, green, and efficiency. Then construct a novel hybrid model which combines the grey incidence clustering model and AP algorithm for panel data in this paper. According to the statistical data from 2014 to 2018, we find out the high-quality development of China's manufacturing industry is characterized by obvious regional differences, different development stages and different constraints.

In 2017, China released the statement of High-Quality Development in response to the sustainable development goals proposed by the United Nations. As the spatial carriers of human economic, social, and cultural development, cities should be updated in order to enter a new period of high-quality urban development. In this paper, we use a multi-period DID model, consider the opening of high-speed railways as a quasi-natural experiment, and use the panel data of 285 prefecture-level and above cities in China from 2007 to 2020 to empirically analyze the effect of high-speed railway (HSR) opening on urban development quality and explore its transmission mechanism. The empirical results find that the HSR opening can significantly promote the level of high-quality urban development. The results remain the same after robustness tests such as PSM-DID and placebo tests. The study mechanism suggests that the HSR opening can significantly improve the quality of urban development through a population agglomeration effect, while capital agglomeration has a masking effect between the HSR opening and high-quality urban development. Further results show that there is heterogeneity in the impact of HSR opening on the high-quality development of cities in different regions and sizes, in which the boosting effect of HSR opening on the development quality of cities in eastern and western regions is more significant compared to cities in central regions; the boosting effect of HSR opening on the high-quality development level of medium-sized cities is stronger.

The scientific community believes that high-quality, bulk layered, semiconducting single crystals are crucial for producing two-dimensional (2D) nanosheets. This has a significant impact on current cutting-edge science in the development of next-generation electrical and optoelectronic devices. To meet this ever-increasing demand, efforts have been made to manufacture high-quality SnS2 single crystals utilizing low-cost CVT (chemical vapor transportation) technology, which allows for large-scale crystal production. Based on the chemical reaction that occurs throughout the CVT process, a viable mechanism for SnS2 growth is postulated in this paper. Optical, XRD with Le Bail fitting, TEM, and SEM are used to validate the quality, phase, gross structural/microstructural analyses, and morphology of SnS2 single crystals. Furthermore, Raman, TXRF, XPS, UV–Vis, and PL spectroscopy are used to corroborate the quality of the SnS2 single crystals, as well as the proposed energy level diagram for indirect transition in the bulk SnS2 single crystals. As a result, the suggested method provides a cost-effective method for growing high-quality SnS2 single crystals, which could lead to a new alternative resource for producing 2D SnS2 nanosheets, which are in great demand for designing next-generation optoelectronic and quantum devices.

In this study, the design and simulation of an 18-channel demultiplexer based on resonant cavities in 2D photonic crystals is proposed. The lattice shape of silicon rods used in this structure is square. To have a reasonable percent transmittance from the input waveguide to resonant cavities, we have used point and linear defects, changing the radius of resonant cavities and adjusting the distance of the dielectric rods around the cavities. The main work of choosing the wavelength is performed by the resonant cavities. Due to a large number of output channels and long distances of the waveguides, the power reflector is used to compensate for the power losses in the waveguide path. The amount of the proposed structure's percentage transmittance is between 90 and 100% and the quality factor is 5383 in the best case. The least bandwidth of the output signal spectra is 0.29 nm, and the amount of crosstalk between the output channels is from − 10 to − 62 dB. The overall dimensions of the proposed structure are 1069µm2. One of the essential applications of the proposed demultiplexer structure is in WDM communication systems. [ABSTRACT FROM AUTHOR]

Controllable nitrogen doping is an effective way to regulate the electronic properties of graphene and further to facilitate its wider application. However, the synthesis of high‐quality nitrogen‐doped graphene (NG) with a controllable nitrogen configuration still faces considerable challenges. In this work, we present for the first time a simple method for the one‐step synthesis of NG with ionic liquids (ILs) as precursors, which avoids the defects introduced by secondary doping and simplifies the process. Using 1‐Ethyl‐3‐methylimidazolium dicyanamide (EMIM‐dca) as the precursor, we obtained a high‐quality NG with few defects (ID/IG is 0.83), nitrogen content (4.11 at%), and graphite‐N proportion of 92% at a growth temperature of 1000 °C and field effect transistors (FETs) fabricated on SiO2/Si substrates using the NG exhibited typical n‐type semiconductor behavior in air. Our findings bring more inspiration for the controllable growth of high‐quality graphitic N‐doped graphene, thereby promoting its application possibilities in numerous fields. [ABSTRACT FROM AUTHOR]

Abstract Background Provider-initiated HIV testing and counseling (PITC) is a recommended approach to screen for HIV to all pregnant women during antenatal care (ANC) visits, and all with HIV positive results have to be enrolled into prevention of mother-to-child transmission of HIV (PMTCT) program. However, little is known about the relationship between facility readiness and the uptake of PITC to pregnant women attending ANC in Tanzania. Therefore, this study assessed whether the facility readiness promotes the uptake of PITC to the pregnant women attending ANC for the purpose of improving the PMTCT interventions in Tanzania. Methods This study analyzed data for health facilities obtained from the 2014–2015 Tanzania service provision assessment survey. The Primary outcome measure was a composite variable (with score of 0–5) in which its higher scores indicates provision of high-quality of PITC. Also, facilities scored higher in the PMTCT service readiness index were considered to have high readiness to provide PMTCT services. In Poisson regression analyses, a series of models were fitted to assess whether there is an association between provision of high-quality of PITC and facility readiness. In all statistical analysis, a P

High-quality Ta-doped ZnSnO 3 single crystal thin films were grown on LiTaO 3 substrates by pulsed laser deposition (PLD) method, and the effects of Ta doping on the lattice structure, surface morphology, electronic structure and photodetector performance of ZnSnO 3 thin films are studied in detail. When the Ta doping content is 1 %, the [0001]-oriented ZnSnO 3 thin film present the highest quality, which the optical band gap (3.75 eV), the smoothest surface roughness (0.83 nm), and the biggest carrier concentration (4.03 × 1019 cm−3). For the solar-blind photodetectors (PDs), based on these excellent characteristics, the 1 % Ta-doped ZnSnO 3 PD exhibits large light-to-dark current ratio (>103), responsivity (21.37 A/W), detectivity ((3.63 ± 0.71) × 10 11 Jones) and external quantum efficiency (∼1.04× 104 %) under 254 nm UV light at an applied bias of 5 V. This study suggests that Ta doping can effectively improve the optoelectronic performance of ZnSnO 3 PDs, laying the foundation for their application. • Ta-doped ZnSnO 3 single crystal thin films are prepared on LiTaO 3 (0001) substrates by PLD method. • The carrier concentration and mobility of Ta-doped ZnSnO 3 films are 4.03 × 1019 cm−3 and 14.7 cm2 V−1 s−1. • Ta-doped ZnSnO 3 photodetector exhibits a good responsivity (21.37 A/W) and light/dark current ratio (>103).

Carbon nanotubes (CNTs) are a significant candidate for future channel materials for high-performance electronic devices, and this has attracted the attention of many researchers. Due to the scattering of defects in carbon nanotubes, the migration of charge carriers is greatly reduced, and the synthesis of defect free carbon nanotubes is an urgent and important issue that needs to be addressed. In this study, high-purity graphite powder served as the carbon source, and iron served as the catalyst to synthesize defect free MWCNTs through direct-current arc discharge (AD) in a nitrogen atmosphere. The effects of different pressures and catalysts on the yield and morphology of CNTs were studied. As the nitrogen pressure inside the vacuum chamber increases, the MWCNTs become longer and more erect. Fe has a high defect repair efficiency, which promotes the synthesizing of lattice-perfect and defect-free MWCNTs. It is found that the MWCNTs mainly exist in the iron mesh near the cathode. Using iron as a catalyst, we synthesize very straight MWCNTs with clearer walls under nitrogen pressure of 60 kPa. The results show that the method is characterized by low cost, implementability, and the ability to synthesize high-quality, defect free MWCNT compared to the conventional AD method. • Carbon nanotubes are synthesized without reducing gases. • High-quality multi-walled carbon nanotubes can be synthesized. • Multi-walled carbon nanotubes with near-perfect graphite lattice structures are synthesized in a 60 kPa N 2.

Background--High-quality development of forestry is an important part of national high-quality development strategy. Scientific construction of forestry high-quality development system is of great significance to the practice of Two Mountains Theory and the promotion of high-quality development of forestry. ⑵ Methods--This paper constructs the measure system of high-quality development of China's forestry through theoretical analysis. Based on the variation coefficient method and the statistical data from 2008 to 2018, this paper measures and analyzes the changing trend and contribution of high-quality development of China" s forestry. ⑶ Results--First, the level of high-quality development of forestry has increased periodically. The high-quality development index of China's forestry in 2008-2018 was 0. 32 〜0. 68, and the annual compound growth rate was 7.83 %. Second, innovation-driven is the key to promoting the high-quality development of China's forestry, with an average contribution rate of 42. 75 %. Therefore, innovation-driven has become an important driving force for the high-quality development of China's forestry. However, compared with the international situation that the utilization of forestry resources is still low and forestry scientific and technological talents are relatively insufficient, in the future, we should continue to increase investment in forestry research and education, and continue to adhere to the new development concept of innovation as the first driving force for forestry development. Third, coordinated development is the inherent requirement to achieve high-quality development of forestry, and the average contribution rate of indicators is 21. 39 %. Fourthly, green resources are an important guarantee for achieving high-quality development of forestry, with an average contribution rate of 22.43 %. Fifth, openness and stability are the main factors that restrict the high-quality development of China" s forestry. The average contribution rate of indicators is -2. 34 %, which hinders the improvement of high-quality development of China's forestry. Sixth, sharing harmony is the short board of high-quality development of China's forestry, the average contribution rate of indicators is 15. 76 %. ⑷ Conclusions and Discussions--According to the constructed evaluation index system of high-quality development of China's forestry, the high-quality development of China's forestry from 2008 to 2018 was measured and analyzed. The results showed that China's forestry experienced three stages of development: medium-low level, medium-low speed, medium-high level and high speed; Innovation-driven is the key to promoting the high-quality development of China's forestry. Coordinated development is the inherent requirement for realizing the high-quality development of forestry. Green resources are an important guarantee for realizing the high-quality development of forestry. Openness and stability are the main factors restricting the high-quality development of forestry, and sharing harmony is the short board for the high-quality development of forestry. There are many important ways for the high-quality development of China's forestry in the future: increasing investment in scientific research and education for forestry, adjusting the structure of forestry employment personnel and narrowing the income gap between forestry and other industries, improving the quality of forest governance and the protection of biological resources, establishing a stable forest product price system and forestry human resources system, transforming ecological resources advantages into economic advantages, and promoting the quality of wages and social security of forestry practitioners by industry.

The integration of the tourism industry is an important motivation in promoting high-quality development. Based on the analysis of the relationship between tourism industry integration and high-quality development, this paper constructs an evaluation index system to evaluate the high-quality development level of the tourism industry for 2011–2018 in China by using a combination of fuzzy mathematics and a clustering model, which includes 4 dimensions, 11 secondary indicators and 28 tertiary indicators. The results show that the level of high-quality development in China's tourism industry has been greatly improved, but the gap between regions is large. The performance level of the tourism industry economy is relatively high, and the tourism industry structure and industrial integration level need to be improved urgently. There are differences in the overall level and degrees of change of the high-quality development level of the tourism industry in 31 provincial regions, and there are also differences in the main influencing factors.

High-quality rice reference genomes have accelerated the comprehensive identification of genome-wide variations and research on functional genomics and breeding. Tian-you-hua-zhan has been a leading hybrid in China over the past decade. Here, de novo genome assembly strategy optimization for the rice indica lines Huazhan (HZ) and Tianfeng (TF), including sequencing platforms, assembly pipelines and sequence depth, was carried out. The PacBio and Nanopore platforms for long-read sequencing were utilized, with the Canu, wtdbg2, SMARTdenovo, Flye, Canu-wtdbg2, Canu-SMARTdenovo and Canu-Flye assemblers. The combination of PacBio and Canu was optimal, considering the contig N50 length, contig number, assembled genome size and polishing process. The assembled contigs were scaffolded with Hi-C data, resulting in two "golden quality" rice reference genomes, and evaluated using the scaffold N50, BUSCO, and LTR assembly index. Furthermore, 42,625 and 41,815 non-transposable element genes were annotated for HZ and TF, respectively. Based on our assembly of HZ and TF, as well as Zhenshan97, Minghui63, Shuhui498 and 9311, comprehensive variations were identified using Nipponbare as a reference. The de novo assembly strategy for rice we optimized and the "golden quality" rice genomes we produced for HZ and TF will benefit rice genomics and breeding research, especially with respect to uncovering the genomic basis of the elite traits of HZ and TF.
