Quantum phase transitions in the anti-Jaynes-Cummings triangle model

We carefully investigate the comprehensive impact of atom-cavity interaction and artificial magnetic fields on quantum phase transitions of anti-Jaynes-Cummings triangle model in the infinite frequency limit. We discover that ground states of the optical field can be a gapped normal phase (NP) or three kinds of gapless superradiant phases with infinite degeneracy. When the atom-cavity coupling is weak, the optical field is in a NP, which is a vacuum with no photons. Otherwise, it will stay at one of the superradiant phases: a normal superradiant phase without photon currents and another two chiral superradiant phases with opposite photon currents. The former only breaks the continuous U(1) symmetry and its gapless excitations are normal Goldstone modes. Nevertheless, the latter, mainly induced by an external synthetic gauge field, break both the continuous U(1) symmetry and chiral symmetry, thereby corresponding gapless excitations are chiral Goldstone modes. In addition, we also propose a detecting scheme to distinguish these superradiant phases.

Artificial intelligence in a modernizing science and technology education: a textual narrative synthesis in the COVID-19 era

The COVID-19 pandemic shifted the mode of learning to online. This gave the artificial intelligence (AI) developers the reason to increase its usage and production to every detail of the teaching learning process. This synthesis paper was intended to capture these new technologies in the last five years. Using the textual narrative analysis approach and course design triangle model, this paper looked into the AI integration in the field of science and technology education. A total of 15 studies were analyzed and synthesized coming from different journal hosting platforms such as Google Scholar, ERIC, Elsevier, etc. The results have shown that there is indeed a wider utilization of AI in various aspects of the teaching and learning process. These were seen in the learning activities, presentation translators, marking, feedbacking, predicting average score, and intelligent tutoring system. These AI technologies have proven to positively affect the learning of the students and helped the teachers along the process. Furthermore, there is a need to totally synthesize these AI systems which can be beneficial to a wider technical audience.

A Critique of the Triangle Method and a Version Suitable for Estimating Soil Moisture from Satellite Imagery

A simple version of the triangle model is proposed, that of a right triangle, which allows one to estimate from remote thermal/optical measurements the evapotranspiration fraction and surface soil moisture availability without reference to external variables even in the absence of a full range of vegetation cover and soil dryness. To date however, the triangle method has yet to be applied widely in the field, partly because of the triangle’s limitations and partly due to its complexity whereby prospective users would be unequipped or unwilling to handle its technical aspects, including its mathematical requirements. After a brief description of the triangle geometry, the paper deals with current misconceptions in the use of the triangle/trapezoid method, including the way in which plants deal with water stress. The last part poses a scenario showing how the right triangle model could be applied easily and routinely at field level by the non-specialist.

Environmental, economic and engineering performances of aqueous carbonated steel slag powders as alternative material in cement pastes: Influence of particle size

The low reactivity and volume expansion issue of steel slag limits its application as alternative to cement. Studies demonstrated that aqueous carbonation (AC) can enhance the cementitious properties of finely sized steel slag as a cementitious supplementary material (SCM). However, the impact of particle size on the CO2 uptake capacity and its association of performance of carbonated steel slag remains unexplored. This study aims to optimize the grinding levels by examining the fineness of the steel slag used as SCM to reduce the high-energy consumption while maintaining the CO2 sequestration and properties of SCM. The results show that reducing the size of steel slag is favorable for CO2 sequestration (particle size 22.4–112.6 μm corresponds to sequestration of ∼88.5–37.9 kg CO2/t steel slag) and improve the leaching of Mg ions for mineralization. The life cycle assessment shows that the global warming potential of AC of steel slag is ∼96.2–24.9 kg CO2-eq/t steel slag, which can offset the carbon emissions due to further grinding. The 28-day compressive strength of the cement pastes blended with finer carbonated steel slag was also relatively higher due to the formation of mono-carboaluminates and stabilization of ettringite in facilitating the bond strength between the carbonated steel slag particle and the cement paste matrix. According to 3E (engineering, environmental and economic) triangle model, 22.4 μm steel slag powder showed the best comprehensive performance, including an increased revenue of 40.8 CNY/ton steel slag.

Cooperative Learning Model Broken Triangle, Square, and Heart: Enhancing Student Engagement and Academic Performance in History Education at the Senior High School Level

Learning models have a significant role in fostering an active, collaborative, and engaging learning environment for students, which is essential for improving academic success in high school history instruction. It is intended that by actively engaging students in the learning process through an efficient learning paradigm, they will become more engaged and make more progress in comprehending and mastering historical content. Through the use of the cooperative learning model Broken Triangle, Square, and Heart, this project seeks to increase the interest and academic performance of high school students in their study of history. A pretest-posttest control group design was used in conjunction with an experimental study methodology. There were 72 students that made up the participants, and they were split into the experimental group and the control group. The choice of study participants was made at random. The distribution of questionnaires served as the method of data gathering. With the aid of SPSS version 25.0, statistical techniques were used to examine the data. The findings of the descriptive statistical analysis showed that both groups' academic achievement and interest levels had increased from the pretest to the posttest. The results of the ANOVA test showed a significant difference between the experimental and control groups' academic performance. The Broken Triangle, Square, and Heart cooperative learning model exposed students in the experimental group to larger improvements in interest and academic accomplishment than did students in the control group, according to the findings of the N-Gain test. The use of the cooperative learning model Broken Triangle, Square, and Heart is successful in boosting the enthusiasm and academic accomplishment of high school students in their study of history, according to the study's findings. The findings of this study have significant educational ramifications and highlight the need to create instructional strategies that actively engage studentss.

An integrated approach for soluble and insoluble pollutants: Surface performance regulation of Co2CO3(OH)2@Ni foam for effective ciprofloxacin removal and oil/water separation

Effectively removing both soluble antibiotics and insoluble oils from wastewater is a significant challenge. To address both the problems, we synthesized a three-dimensional (3D) porous water treatment material. It can be converted from antibiotic removal mode to oil removal mode by simple surface performance regulation. This approach achieved a high removal rate for ciprofloxacin (CIP) and good separation efficiency for oil/water mixtures. Initially, Co2CO3(OH)2 nano-needles were fixed on Ni foam to synthesize Co2CO3(OH)2@Ni foam-1, which had a high CIP removal rate (93.59 % at pH 7.0) and a certain anti-interference ability. To assess the CIP removal performance, the environmental impact, economic benefit and energy consumption (3E) triangle model was established and the optimal operating point was selected. Characterization experiments demonstrated that the removal of CIP was attributed to the mechanisms of surface complexation, electrostatic attraction, cation bridging, precipitation and flocculation. Subsequently, Co2CO3(OH)2@Ni foam-2 was obtained by hydrophobic modification, which exhibited separation efficiencies above 93.5 % for a series of different oil/water mixtures. Co2CO3(OH)2@Ni foam series materials are easy to prepare and possess effective pollutants treatment efficiency, thus providing a new strategy for developing multi-functional water treatment materials and a novel approach for the treatment of soluble antibiotics and insoluble oils in wastewater.

Laboratory-Scale Low-Speed Water Tunnel: Comparison of Experimental Flow Visualization and Computer-Aided Simulation

This study aimed at developing the laboratory-scale low-speed water tunnel design by first evaluating the effect of varying the number of wide-angle diffuser vanes and then confirming flow visualization against object geometries tested by experiments and computer-aided simulation. The low-speed water tunnel design in this study consists of a wide-angle diffuser, a honeycomb, a convergent section, and a working section. To ascertain the laminar flow of water would act in the experiment, a prior simulation using 3, 6, and 12 vanes and without a vane was conducted. Some geometries, including tube, triangle, aerofoil, and car models have been tested and then compared to the experimental results. The results indicate that the twelve vanes diffuser is more effective in minimizing turbulent flow and producing a streamlined pattern in the water tunnel. Laminar flow with a Reynolds number of 2238 and flow velocity of 0.008 m/s was obtained in the working section. The flow visualization by experiment and computational fluid dynamics simulation was almost similar.

Effects of Soil Arthropods on Non-Leaf Litter Decomposition: A Meta-Analysis

According to the widely accepted triangle model, global litter decomposition is collectively controlled by climate, litter initial quality, and decomposers. However, the specific contribution of soil arthropods to litter, especially the non-leaf litter, the decomposition of terrestrial ecosystems and its drivers are still unclear. We conducted a global meta-analysis based on 268 pairs of data to determine the contribution and pattern of soil arthropods to branch, stem, and root litter decomposition in farmlands, forests, and grasslands and analyzed the relationship of soil arthropods’ decomposition effect and potential drivers. Our results showed that: (1) soil arthropods increased global non-leaf litter mass loss by 32.3%; (2) the contribution varied with climate zone and ecosystem type, with a value of subtropical (53.3%) > temperate (18.7%) > tropical (14.7%) and of farmlands (40.6%) > grasslands (34.3%) > forests (0.6%), respectively; (3) the soil arthropods’ decomposition effect gradually decreased with decomposition time, and it was higher in litterbags with a mesh size of 1–2 mm (65.4%) and >2 mm (49.8%) than that of 0.5–1 mm (13.6%); (4) the soil arthropods’ decomposition effects were negatively correlated with the litter initial C/N ratio, mean annual precipitation (MAP; p < 0.001), and elevation and was positively correlated with litter weight. In conclusion, soil arthropod promoted global non-leaf litter decomposition, and the contribution varied with climate zone, ecosystem type, and decomposition time as well as litterbag mesh size. Overall, this study improves the understanding of soil arthropods driving global non-leaf litter decomposition.

Субъективные права в непредписывающем правовом регулировании: методологические основы исследования

Subjective rights have been and are the subject of scientific focus both in this country and abroad. However, all these numerous studies sinby myriad mistakes and inaccuracies. This is a serious obstacle to the creation of a relevant to objective state-legal reality theoretical model of the use of subjective rights in the legal regulation. In turn, this makes it impossible to formulate a correct scientific foundation for improving not only legal activity, but also the entire public administration. Purpose. To avoid the methodological problems of legal science that lead to the noted errors and inaccuracies, the paper does not allow mixing of political-ideological and scientific, logical, approach to the phenomena studied. As a result of the analysis of the ontological status of subjective law in the informational aspect, the author concludes that this right does not have its own prescriptive nature, but is associated with prescriptions in the context of the legal semiotic triangle model. The pragmatic aspect of the analysis of the regulatory nature of subjective rights makes it possible to find the real place of these rights in the mechanism of non-prescriptive legal regulation. Conclusions. In the logical-semantic context, subjective law is not a prescription, but a duplicate or indirect exponent of a legal prescription. At the same time, the specifics of the formulation of such an exponent relate to factors of a pragmatic, political and ideological nature. Taking into account these factors allows interpreting subjective rights as special socio-legal assessments of antelegem, prelegem, sucundumlegem, praeterlegem, postlegem, which relate to a phenomenon poorly studied by legal science that has extremely important practical significance.

Policymaker perspectives on self-management of disease and disabilities using information and communication technologies

BackgroundPolicies that support health self-management are malleable and highly dependent on various factors that influence governments. Within a world that is shifting toward digitalization due to pressures such as the COVID-19 pandemic and labor shortages, policymaking on older adults’ self-management of chronic diseases and disability using information and communication technologies (ICTs) needs to be better understood. Using the province of Ontario, in Canada, as a case study, the research question was What is the environment that policymakers must navigate through in development and implementation of policies related to older adults’ self-management of disease and disability using information and communication technologies (ICTs)?MethodsThis study used a qualitative approach where public servants from 4 ministries within the government of Ontario were invited to participate in a 1-h, one-on-one, semi-structured interview. The audio-recorded interviews were based on an adapted model of the policy triangle, where the researcher asked questions about the influences from the different sources identified in the model. The interviews were later transcribed and analyzed using a deductive-inductive coding approach.ResultsTen participants across 4 different Ministries participated in the interviews. Participants shared insights on various aspects of context, process and actors that help shape the current content of policies. The analysis revealed that policies, in the form of programs, services, legislation and regulations, are the result of collaborations and dialogue between different actors and get developed and implemented via a set of complex government processes. In addition, policy actions come from a plethora of sectors which all get influenced by several predictable and unpredictable external pressures.ConclusionsThe environment for policymaking in the government of Ontario regarding older adults’ self-management of disease and disability using ICTs is one that is mostly reactive to external pressures, while organized within a set of complex processes and multi-sectoral collaborations. The present research helped us to understand the complexity of policymaking on the topic and highlights the need for increased foresight and proactive policymaking, regardless of which governments are in-place.

How small organisations develop sustainability-oriented strategies: evidence from northwest Himalayas

PurposeUsing Gibson and Tarrant's (2010) resilience triangle model, this study explores how small northwest Himalayan organisations respond to contextual challenges and opportunities and embed sustainability strategies in the organisations' operational values.Design/methodology/approachA qualitative exploratory design through individual and group interviews with owner-managers and employees was held in five small northwest Himalayan organisations.FindingsThe findings reveal multiple contextual challenges facing small organisations in northwest Himalayas, including ecological conditions, remoteness, underdeveloped infrastructure and human competencies. The investigated organisations respond to these challenges through reactive and innovation-based services like eco-tourism, conservation and educational initiatives. The organisations engage communities through participatory and educational activities. Owner-managers adjust the respective vision and mission statements, train employees on sustainability values and lobby the government on policy changes to embed sustainability strategies. Some organisations invest in resources and capabilities and others in process capabilities.Practical implicationsSmall organisations can improve how the organisations predict contextual issues by developing the organisations' process capabilities, specifically by creating practical tools with parameters relevant to ecological conditions. These organisations can set the tools through participatory actions with the broader communities to ensure the (un)intended consequences of environmental issues are considered. Furthermore, improvements in process and human capabilities will provide new approaches to raising business opportunities, especially in post-pandemic business environments.Originality/valueThis study develops a framework that enhances the understanding of how process capabilities, leadership, people and knowledge capabilities are critical to developing and embedding sustainability strategies in small organisations.

Is economic policy uncertainty an excuse for corporate fraud?

This study examines the dynamic relationship between economic policy uncertainty (EPU) and corporate fraud by using a sub-sample time-varying rolling window test. Corporate fraud is classified as fraud incidents (the number of corporate frauds) and fraud magnitude (the severity of corporate frauds). Based on this, we propose an EPU-Fraud Triangle model to evidence that EPU affects corporate fraud by acting on Pressure, Opportunity, and Rationalization. The empirical results show that corporations are more likely to engage in fraud during high EPU periods. Moreover, corporate fraud has positive impacts on EPU. As a result, this study suggests corporations consider fraud consequences and policy trends when making decisions. Additionally, government policymakers should analyze the causes of corporate fraud to develop appropriate policies. In addition, to minimize information asymmetries, investors should pay attention to corporate fraud and remain knowledgeable of national policy trends. Furthermore, the study can contribute to the smooth functioning of macroeconomics and reduce the probability of financial risks.

A Hermite Surface Triangle Modeling Method Considering High-Precision Fitting of 3D Printing Models

Three-dimensional printing is a layer-by-layer stacking process. It can realize complex models that cannot be manufactured by traditional manufacturing technology. The most common model currently used for 3D printing is the STL model. It uses planar triangles to simplify the CAD model. This approach makes it difficult to fit complex surface shapes with high accuracy. The fitting result usually suffers from loss of local features of the model, poor fitting accuracy, or redundant data due to face piece subdivision, which will cause problems such as poor manufacturing accuracy or difficult data processing. To this end, this paper proposes a method for constructing Hermite surface models considering high-precision fitting of 3D printing models. The mapping relationship between different surface triangles and the same base triangle is established by analyzing the characteristics of Hermite surface triangles in AMF format files and using the radial variation property. By constructing a cubic surface model with general parameters and combining the vertex and tangent vector information, a cubic Hermite curve and surface triangle model are obtained. A sampling mapping point solution method is proposed, which transforms the volume integration problem between models into the summation problem of sampling point height difference. Considering the mean deviation and variance in multiple directions of the sampling points, a method for calculating and evaluating the model fitting error is constructed. Finally, the effectiveness of the proposed method is verified by rabbit and turbine.

Selective modes affect gene feature and function differentiation of tetraploid Brassica species in their evolution and domestication.

The genus Brassica contains a diverse group of important vegetables and oilseed crops. Genome sequencing has been completed for the six species (B. rapa, B. oleracea, B. nigra, B. carinata, B. napus, and B. juncea) in U's triangle model. The purpose of the study is to investigate whether positively and negatively selected genes (PSGs and NSGs) affect gene feature and function differentiation of Brassica tetraploids in their evolution and domestication. A total of 9,701 PSGs were found in the A, B and C subgenomes of the three tetraploids, of which, a higher number of PSGs were identified in the C subgenome as comparing to the A and B subgenomes. The PSGs of the three tetraploids had more tandem duplicated genes, higher single copy, lower multi-copy, shorter exon length and fewer exon number than the NSGs, suggesting that the selective modes affected the gene feature of Brassica tetraploids. The PSGs of all the three tetraploids enriched in a few common KEGG pathways relating to environmental adaption (such as Phenylpropanoid biosynthesis, Riboflavin metabolism, Isoflavonoid biosynthesis, Plant-pathogen interaction and Tropane, piperidine and pyridine alkaloid biosynthesis) and reproduction (Homologous recombination). Whereas, the NSGs of the three tetraploids significantly enriched in dozens of biologic processes and pathways without clear relationships with evolution. Moreover, the PSGs of B. carinata were found specifically enriched in lipid biosynthesis and metabolism which possibly contributed to the domestication of B. carinata as an oil crop. Our data suggest that selective modes affected the gene feature of Brassica tetraploids, and PSGs contributed in not only the evolution but also the domestication of Brassica tetraploids.

Becoming a Non-native Chinese Language Teacher: An Identity Triangle Model Analysis

This study utilises the Identity Triangle Model (Dugas in Teach Dev 25(3):243–262, 2021, https://doi.org/10.1080/13664530.2021.1874500) to examine the experiences of one particular novice non-native Mandarin Chinese teacher at a university in New Zealand. A case study design was employed to track the identity negotiations of this European non-native Chinese speaker during 12 weeks of her first semester of teaching. Analysis of the data revealed nine subcategories within the psychological, behavioural, and relational domains according to the Identity Triangle Model. The findings suggest that this new non-native speaker teacher viewed her as an accidental teacher, exploring a teaching career without a strong instrumentalist aspiration or a clear career path in language teaching. Instead, she was more motivated by a desire for personal growth and the opportunity to reinvent themselves in a new cultural context. The results of this study offer theoretical implications for the adoption of a unified framework in future research on the identity of first-time language teachers, and practical implications for developing sustainable strategies aimed at recruiting and retaining non-native speaker teachers in foreign language education.
