Sliding-window cross-correlation and mutual information methods in the analysis of solar wind measurements
Authors: Gu Chaoran , Heidrich-Meisner Verena , Wimmer-Schweingruber Robert F.
Published: February 2024

Context. When describing the relationships between two data sets, four crucial aspects must be considered, namely: timescales, intrinsic lags, linear relationships, and non-linear relationships. We present a tool that combines these four aspects and visualizes the underlying structure where two data sets are highly related. The basic mathematical methods used here are cross-correlation and mutual information (MI) analyses. As an example, we applied these methods to a set of two-month’s worth of solar wind density and total magnetic field strength data.

Aims. Two neighboring solar wind parcels may have undergone different heating and acceleration processes and may even originate from different source regions. However, they may share very similar properties, which would effectively “hide” their different origins. When this hidden information is mixed with noise, describing the relationships between two solar wind parameters becomes challenging. Time lag effects and non-linear relationships between solar wind parameters are often overlooked, while simple time-lag-free linear relationships are sometimes insufficient to describe the complex processes in space physics. Thus, we propose this tool to analyze the monotonic (or linear) and non-monotonic (or non-linear) relationships between a pair of solar wind parameters within a certain time period, taking into consideration the effects of different timescales and possible time lags.

Methods. Our tool consists of two parts: the sliding-window cross-correlation (SWCC) method and sliding-window mutual information (SWMI) method. As their names suggest, both parts involve a set of sliding windows. By independently sliding these windows along the time axis of the two time series, this technique can assess the correlation coefficient (and mutual information) between any two windowed data sets with any time lags. Visualizing the obtained results enables us to identify structures where two time series are highly correlated, while providing information on the relevant timescales and time lags.

Results. We applied our proposed tool to solar wind density and total magnetic field strength data. Structures with distinct timescales were identified. Our tool also detected the presence of short-term anti-correlations coexisting with long-term positive correlations between solar wind density and magnetic field strength. Some non-monotonic relationships were also found.

Conclusions. The visual products of our tool (the SWCC+SWMI maps) represent an innovative extension of traditional numerical methods, offering users a more intuitive perspective on the data. The SWCC and SWMI methods can be used to identify time periods where one parameter has a strong influence on the other. Of course, they can also be applied to other data, such as multi-wavelength photometric and spectroscopic time series, thus providing a new tool for solar physics analyses.
Nourrir sans détruire avec des systèmes alimentaires territorialisés durables : le cas de l’espace Afrique-Europe
Authors: Rastoin Jean-Louis , Seck Papa Abdoulaye
Published: February 2024

Après quatre transitions technologiques et organisationnelles en 400 000 ans, l’humanité est en quête d’une sécurité alimentaire durable et partagée. En effet, les lourdes externalités négatives du système agro-industriel devenu hégémonique en 150 ans incitent à reconstruire les systèmes alimentaires dans une perspective socio-écologique. Sur la base d’une synthèse de diverses prospectives, les auteurs présentent le scénario alternatif de « systèmes alimentaires territorialisés durables » (SATD) fondés sur la qualité élargie des produits, l’autonomie territoriale, la proximité et la solidarité. Un tel scénario induirait de profonds changements dans les pays du Nord et du Sud, avec des trajectoires contextualisées. Pour l’Europe, il s’agit d’une rupture de tendance. En Afrique, la faible prégnance du modèle agro-industriel suggère une orientation directe vers des SATD, sans passer par ce modèle agro-industriel. À partir de considérations théoriques et empiriques, quatre préconisations sont faites à l’intention des décideurs publics et privés : planification stratégique, prévention des risques par le concept « une seule santé », redéploiement de la chaîne des savoirs, reconfiguration des filières agro-alimentaires et de leurs modes de gouvernance.
Pour une gestion durable des sols en Afrique subsaharienne
Authors: Dugué Patrick , Andrieu Nadine , Bakker Teatske
Published: February 2024

La faible productivité de l’agriculture en Afrique subsaharienne est due en grande partie à la dégradation de la fertilité des sols. Les agricultures familiales, pilier de la sécurité alimentaire de cette grande région, doivent relever le défi de la restauration et du maintien de la capacité productive des terres. Les pratiques endogènes des producteurs telles que les associations céréales-légumineuses, les jachères pâturées, les parcs arborés... ne permettent plus d’entretenir la fertilité sur des surfaces cultivées qui s’agrandissent, surtout lorsque les sols sont carencés. Durant quatre décennies, les décideurs et acteurs du secteur agricole ont privilégié la vulgarisation des engrais de synthèse. Mais l’utilisation des engrais minéraux demeure faible et bien en deçà de la moyenne de la consommation mondiale (15 kg/ha contre 135 kg/ha). Après avoir longuement promu l’utilisation de fumure organique, la recherche invite désormais à diversifier les sources de biomasse fertilisante via l’agroforesterie, les associations avec les légumineuses, l’agriculture de conservation. D’autres techniques de conservation de l’eau et du sol ont également été mises en avant. C’est bien la combinaison de différentes pratiques qui est à construire avec les agriculteurs pour chaque situation de production, en fonction des ressources disponibles localement, d’un apport raisonné d’engrais de synthèse et d’amendement, des savoirs paysans et scientifiques. Pour cela, il est nécessaire (i) de modifier les postures des chercheurs et des décideurs vis-à-vis des ruraux et (ii) de réviser les politiques publiques toujours focalisées sur l’usage des engrais minéraux, afin de fournir des services d’appui-conseil plus diversifiés, performants et intégrant les besoins de transitions agroécologiques indispensables aujourd’hui dans un contexte de changement climatique.

Published: February 2024

In this paper, we prove existence of weak solutions in W1,20 (Ω) ∩L∞(Ω) for the gradient coupled Dirichlet system

{u ∈ W1,20 (Ω): –div(M(x)∇u) + u + a(x)∇u · ∇ψ = f(x),

{ψ ∈ W1,20 (Ω): –div(M(x)∇ψ) + ψ + a(x)∇u · ∇ψ = g(x).

We also prove that if f (x), g(x) ≥ 0 (of course ≢ 0 a.e.), then u(x), ψ(x) ≥ 0 and the sets {u = 0} and {ψ = 0} have zero Lebesgue measure.

Published: February 2024

The impact of various factors such as microbes, allergens, inadequate environmental conditions, pollutants, and suboptimal building materials on human health within indoor environments is of utmost importance due to the significant amount of time people spend inside buildings. The objective of this study was to assess the combination of Portland cement (PC) with Titanium Oxide (TiO2) nano powder for antimicrobial properties with good physical and mechanical strength. TiO2 was added to PC at various percentages (0.5%, 1.0% and 1.5% by the weight of cement) and analysis of slump flow, compressive strength and flexural strength were determined. The antimicrobial activity was evaluated by agar diffusion test, utilizing 4 bacteria strains: Escherichia coli, Staphylococcus aureus, Enterococcus faecalis and Pseudomonas aeruginosa. Results showed that the addition of TiO2 increased the mechanical strength of the specimen with 1.0% TiO2 displaying the optimum result. For the antimicrobial activity, samples with 1.05% TiO2 had the highest efficiency in inhibiting bacteria growth. The findings showed that a lower percentage of TiO2 added to the PC mortar significantly enhances its mechanical properties and is efficient in inhibiting the growth of bacteria. Such mortar mixture with antibacterial properties should be utilized to enhance hygiene conditions in diverse environments, including hospitals, institutional kitchens, etc., where such properties are necessary.

Published: February 2024

Due to intermittent nature of solar energy, scientists and researchers are working to develop thermal energy storage (TES) systems for effectively use the solar energy. One promising avenue involves utilizing phase change materials (PCMs), but primary challenge lies in their limited thermal conductivity, which results in slower heat transfer rate and lower thermal energy storage density. The present research work demonstrates, to develop and explore a PCM composite by embedding salt hydrate and coper (II) oxide to enhance the heat transfer mechanism for potential utilization of TES material. The optical behavior, and thermal conductivity were analyzed by using Ultraviolet visible spectrum, and thermal property analyzer. The developed copper oxide dispersed PCM composite displayed the thermal conductivity was energized up to 71.5 % without affecting the other properties. Also, the optical absorptance was remarkably enhanced and the transmittance reduced to 87 %. Increasing the concentration of copper oxide nanoparticles in the salt hydrate PCM improves the optical absorptivity and heat conductivity. With these extraordinary abilities the nanocomposite could play a significant role in progress of sustainable TES with significance to contribute towards sustainable development goal of affordable and clean energy and climate change.

Published: February 2024

This study focuses on investigating the thermo-hydraulic performance and entropy generation rate of an evacuated tube solar collector using MXene/Soybean oil as a working nanofluid by means of Computational Fluid Dynamics (CFD). A complete 3-D geometry is considered using three different kinds of working fluids (water, soybean oil and MXene/Soybean oil-0.025 wt.%, 0.075 wt.%, and 0.125 wt.%) for five different mass flow rates (0.02475 kg/s, 0.04818 kg/s, 0.0717 kg/s, 0.0952 kg/s, and 0.1188 kg/s) under same solar radiation (925W/m2). The results revealed that MXene/SO-0.125 wt.% at 0.0717 kg/s showed the best thermo-hydraulic performance because it achieves the balance between a high heat transfer coefficient and a low-pressure drop. However, MXene/SO-0.125 wt.% has been shown to have the highest entropy generation rate compared to other loadings because thermal efficiency is directly proportionate to the entropy generation rate. Therefore, the final recommendation for the best working fluid is MXene/SO 0.075 wt.% at 0.4818 kg/s because it attains good thermal efficiency, low entropy generation rate, and when compared to water has shown the highest improvement of 31.1%.

Published: February 2024

In recent years, numerous studies have been conducted to combine tin oxide (SnO2) with various semiconductor materials to boost its photocatalytic efficiency for water waste treatment, with minimal emphasis placed on intensifying the intrinsic capabilities of pure SnO2. The primary objective of this study is to enhance the photocatalytic efficiency of pure SnO2 nanoparticles (NPs) by modifying their morphology, structural, and optical properties. The SnO2 NPs were synthesized using precipitation method, followed by a calcination process at varying temperatures (non-calcined, 300 °C, and 500 °C). The changes in properties of SnO2 NPs were investigated utilizing X-ray diffraction (XRD), scanning electron microscopy (SEM), particle size analysis (PSA), Brunauer-Emmett-Teller (BET), and ultraviolet-visible (UV-Vis) spectroscopy. The results indicated that elevating the calcination temperature up to 500 °C resulted in an increase in both the average crystallite size (up to 10.50 nm) and crystallinity (up to 85.28 %). However, the highest photocatalytic efficiency for methylene blue degradation of 84.78 % was obtained from the SnO2 NPs calcined at 300 °C sample exhibiting the largest surface area of 83.97 m2g-1. This study affirms that the specific surface area of SnO2 NPs is a critical factor in their efficacy for degrading dye-contaminated water waste.

Authors: Usman Adebanjo Abiola , Shafiq Nasir , Abd Razak Siti Nooriza , Kumar Vicky , Farhan Syed Ahmad
Published: February 2024

Incorporation of antimicrobial agents in concrete can enhance the resistance of the concrete to biodeterioration. However, there is lack of adequate knowledge on the effect of antimicrobial agents on performance measures of high-performance concrete (HPC), particularly during early strength development, when the hydration reaction is ongoing, is not well understood. Therefore, the effect of antimicrobial agents on early compressive strength (CS) of HPC was investigated. The cement in HPC samples was partially replaced with nanosized titanium dioxide (TiO2) and zinc oxide (ZnO) by up to 2% by weight of the cement. Using response surface methodology, 21 combinations of TiO2 and ZnO contents were generated. The combinations were adopted for preparation of the samples. Individual and combined effects of TiO2 and ZnO on 7-day CS of the samples were evaluated. The standard form of the second-order response surface model is adopted to develop a model to fit the strength data. Statistics of the data verify that the model can be employed to predict the 7-day CS of HPC that employs nanosized TiO2 and ZnO as antimicrobial agents.
Carbon dioxide adsorption on shale: A comparative study of isotherm models across diverse samples and temperatures
Authors: Hussain Zaheer , Farhah Dzeti
Published: February 2024

In order to address one of the most serious environmental concerns of our day, reducing carbon footprints, the globe has turned its attention to carbon dioxide (CO2) storage as a potential solution. Because of its unique features, shale is one of the most intriguing options in this area. Adsorption is the method through which CO2 is stored in shale, particularly in its supercritical condition. Adsorption isotherm models can be used to deduce the behaviour and mechanisms of this adsorption. Langmuir, Freundlich, Dubinin-Astakhov (D-A), and Brunauer-Emmett-Teller (BET) models are among the many available for CO2 modelling on shale. We attempted to fit these models to experimental data gathered from literature sources in this study, concentrating on four separate shale samples from various places in China. Among these samples are LMX1 and LMX2 from the Silurian Longmaxi Formation, WF1 from the Ordovician Wufeng Formation in the Sichuan Basin, and YC from the Ordos Basin's Yanchang Formation. The total organic carbon (TOC) content of these shales, three marine and one continental, ranged from 3.19 to 4.27. The experimental data used to fit the model was obtained at three different temperatures: 35, 45, and 55°C. The Langmuir and D-A models offered the best fit for the data across all samples and temperature. R2 values 0.93429 (for YC rock at 35°C) to 0.99287 (for WF1 at 35°C) for Langmuir and 0.88879 to 0.99201 LMX1 at 35°C. The theoretical underpinnings of these models, which account for the physical properties and adsorption dynamics of supercritical CO2 on shale, are responsible for their performance. Finally, this study adds to our understanding of CO2 adsorption on shale, giving useful insights for future research and potential practical uses in CO2 storage. More research is needed, however, to completely understand the mechanisms and influencing factors of CO2 adsorption in various types of shale, as well as to develop the models used to forecast this behaviour.

Published: February 2024

Cancer is the second leading cause of death worldwide and is having a serious impact on the global economy. Various treatment modalities are in use to treat cancer but none of the techniques is risk-free. Recently, various nanomaterials such as gold, boron, and other compounds have been investigated for radiotherapy and as anti-cancer drug carriers with promising results. MXenes are 2D novel nanomaterials and their biomedical and anticancer properties are gaining interest due to their high biomedical activity, less bio-toxicity, and photo-responsive nature. However, the biological properties of MXense have not been studied extensively, therefore, limited data is published on its in-vitro and in-vivo anticancer activities, drug loading efficacy, targeted release, and on its photothermal therapy response. In this review, we have discussed the use of nanoparticles and MXenen nanomaterial in cancer therapy. Furthermore, the role of Mxene as a photothermal agent and drug carrier has also been emphasized, along with the present challenges for the use of nanomaterials in the treatment of cancer.

Published: February 2024

This paper is devoted to applying the inverse Data Envelopment Analysis (InvDEA) in the simultaneous presence of desirable and undesirable factors. One of the most common ways to improve units’ performance in the business environment is through activity synergies called units’ merging. The present study models how to identify the inherited input/output from the units participating in the merger process to achieve the desired efficiency goal. The proposed models are established based on the InvDEA approach and multiple-objective programming tools. Sufficient conditions to estimate desirable and undesirable data are obtained using Pareto solutions to multi-objective programming problems. The theory extended in the study is explained by an application in the banking sector.

Authors: Wu Zhihui , Lang Hong
Published: February 2024

In this paper, the differential game model is constructed to study the coordination problem of platform supply chain by introducing the impacts of Big Data marketing and reference promotion effect on consumer conversion rate. Firstly, the optimal strategies and the profits under centralized and decentralized modes are given by applying the optimal control theory, and the comparative analyses are carried out. Subsequently, in order to coordinate the platform supply chain, a combined contract including a two-part tariff scheme and a promotion cost sharing scheme is designed. Finally, the effects of system parameters on equilibrium strategies and coordination contract are analyzed. The results show that the respective decisions of the manufacturer and the e-commerce platform as well as the total profit of the supply chain are higher under centralized mode. Moreover, within the feasible region, the combined contract not only achieves channel coordination but also improves the economic situations of channel members. It can be also observed that the coordination capacity of the proposed contract reduces with an increase in the memory parameter and improves with an increase in parameters such as the effectiveness of the Big Data marketing and the effectiveness of the reference promotion effect.

Published: February 2024

The implementation of personalised learning in teaching English has become one of the effective approaches to cater learners’ needs in education. The educators in Malaysia, as in many countries, are interested in exploring the implementation of personalised learning in their lessons. However, the study on personalised learning to teach English in Malaysian schools is scarce. The prevalence of low academic achievement, especially in rural and low-enrolment schools, has led to teacher reluctance to adopt personalised learning approaches, potentially denying students the vital benefits of tailored education essential for their future success and development. Hence, this study aims to explore the implementation of personalised learning to teach English, particularly in Malaysian lowenrolment schools, as well as the challenges and ways to overcome the challenges. Personalised learning is implemented based on the SelfDetermination Theory in this study. This qualitative research used a narrative approach via oral history. Purposive and convenience sampling were used to select a total of four participants for this study. Online semistructured interviews were conducted with the participants to collect the data. The result analysis was trifold, including data transcription, data coding and data analysis to explore the research questions. Findings show that the implications of personalised learning in low-enrolment schools, grounded in the principles of Self-Determination Theory, are vast and promising. Personalised learning in English language education has the potential to transform Malaysia’s educational landscape by nurturing intrinsic motivation, enhancing language skills, engaging students culturally, supporting teacher development, and fostering systemic changes, ultimately improving academic achievement, engagement, and well-being.

Authors: Setiawan Irma
Published: February 2024

Language acquisition in bilingual children is a process of transferring two languages simultaneously to children by both parents or the environment. This is what happened to Nadira (pseudonym -a Sasak child aged three years and four months), who was often taught two languages (Sasak Indonesian) in the process of her growth and development. As a result, Nadira’s speech has a distinctive phonosyntactic effect due to the simultaneous incorporation of the Sasak and Indonesian languages. This effect includes the Sasak language’s Indonesianized structure, Sasakized Indonesian phonology, and the process of sound changes in morphs. The aim of this research is to describe various aspects of language acquisition in bilingualism in the Sasak tribe. Meanwhile, the assessment theory used was Chomsky’s view. Data collection was carried out using the listening and skill method as well as basic and derivative techniques, observation techniques, and documentation. The collected data was analyzed using a qualitative descriptive method, which aims for systematic description, categorization, and patterning. As a result, a unique and distinctive reality of language acquisition occurs in the speech of children in the Sasak tribe.

Influence of audience on the home advantage: a comparative study in French Rugby union and Football championships before and during Covid-19 pandemic
Authors: Thon Bernard , Doutreloux Jean-Paul
Published: February 2024

Several sources suggest that the behavior of supporters is as important as their number in the stadium in influencing the advantage of playing at home in team sports. Some studies indicate that Football fans display more violent behaviors than Rugby ones and we hypothesized that they contribute more importantly to the home advantage. We analyzed the performances of the teams involved in the highest level of Rugby union and Football French championships during 2019-2020 season (with fans in the stadiums) and the 2020-2021 season (without public). Results revealed that the advantage of playing at home is significant when public was present in both sports. However, when fans were not present, this advantage disappeared in Football but remained unchanged in Rugby union. So, crowd attendance is an important factor in determining Home advantage (or Away disadvantage) in Football, but not in Rugby union. These results are discussed in terms of differences in fans behavior in the two sports, and we hypothesized that the feeling of territoriality is more important in Rugby union than in Football.
Enhancing the corporate social & environmental responsibility of Chinese energy enterprises: A view from the role of management compensation incentive
Authors: He Jiaxin , Li Jingyi , Chen Xing
Published: February 2024

Energy enterprises are an important basis for ensuring national energy security and economic development, and their social responsibility is closely related to addressing environmental concerns such as over-exploitation of resources and excessive discharge of pollution. The casual effects of management compensation incentives on corporate social & environmental responsibility are explored based on the panel data of Chinese energy enterprises from 2010 to 2021 using the instrumental variable estimation method. The results indicate that management salary incentives can significantly promote the implementation of corporate social responsibility and environmental responsibility, while the proportion of management shareholding will reduce corporate social responsibility (CSR) and environmental responsibility (CER) activities. In addition, there are obvious industry differences and corporate ownership differences in the effects of management compensation incentives on CSR and CER. The negative impact of equity incentives on CSR and CER is even more pronounced in the electricity and environmental industry, and salary incentives have a greater positive effect on CSR for state-owned enterprises. The study shows that enterprises should focus on the salary incentive of managers and appropriately reduce their shareholding. The government should pay attention to the development of state-owned energy enterprises, and limit the shareholding ratio of management through policies and other incentive systems.

Media representations are susceptible to attitudes. This study examined how the press frames the attitudes of Western, non-Western, and Saudi newspapers towards employing Saudi women in the military, a topic which has formed a rich area of interest for the press between 2018 and 2023. To that end, a corpus comprising 29 articles (10,288 words) from both local and international publications was compiled, with the purpose of conducting critical discourse analysis. The study analysed corpus concordances both quantitatively and qualitatively seeking to identify attitudes generated through language and discourse, either implicitly or explicitly. Following Van Dijk’s socio-cognitive approach, the study identified keywords and co-occurrent patterns. It was found that news articles could be classified into three patterns of their representation of Saudi women empowerment: advocating, biased and neutral. This study offers a reflection on how the linguistic features of newspapers frame females and address female issues on diverse grounds.
Intersecting language and society: a prototypical study of Cinderella story translations in China
Authors: Liu Yanjin , Li Dechao
Published: February 2024

The stories of Cinderella, highlighting the theme of kindness, are classic children’s literature worldwide. In China, the translation of the Cinderella stories has been listed in the Chinese textbook series launched in 2004, exerting a profound influence on generations of Chinese readers. This study investigates howHuiguniang, the Chinese counterpart of the character Cinderella, has become a household name among Chinese children. By examining the changes, correlations, and shifts of their prototypical features under the framework of the Aarne-Thompson-Uther classification in the three Chinese translations of the Cinderella stories and the ancient Chinese folkloreThe tale of Ye Xian, the study examines how factors such as external stability, internal dynamic trade-offs, and the iterative nature and empowerment of translation have popularized and canonizedHuiguniangin China. The study further extends its focus within the broader context of discourse studies, embracing the intersections of language and society, as it brings to light the intricate dynamics of translation, empowerment, and cultural reception.

Adaptive multi-paddock (AMP) grazing is hypothesised to improve livestock diet quality by allowing managers to move livestock among paddocks in a manner that tracks phenological variation in forage growth related to variation in plant community composition. We compared yearling steer (Bos taurus) dietary crude protein (CP), digestible organic matter (DOM), and diet composition on a ranch-scale (2600 ha, 10 pairs of 130 ha paddocks) experiment in shortgrass steppe for 6 years (2014–2019) in contrasting grazing treatments: Collaborative Adaptive Rangeland Management (CARM, a type of AMP with a stakeholder group making science-informed management decisions within the grazing season) and season-long, continuous grazing (TRM, traditional rangeland management). These grazing treatments had the same system-level stocking rate annually but differed in stocking density, with CARM being 10-fold higher than TRM because of all steers in the CARM treatment being in a single herd. Mean grazing-season dietary CP was consistently 13–28% higher in TRM than CARM; in contrast, DOM in TRM was similar to CARM or only slightly higher (2.5%). Differences in diet quality between CARM and TRM grazing strategies were largest early in the grazing season, with CP being 14–36% higher for TRM compared to CARM steers during the first 4 weeks; these diet-quality differences between treatments disappeared towards the end of the grazing season. Implementing AMP on the basis of a diverse stakeholder group’s experiential knowledge about plant communities, soils, and ecological sites did alter within-grazing season plant functional group contributions to steer diets. Although we implemented adaptive decision-making within the grazing season, which allowed CARM steers to track the seasonal phenology of C3 versus C4 grasses as steers rotated among paddocks varying in plant community composition, these adaptive movements did not offset the detrimental effects on diet quality associated with grazing in a herd with 10-fold higher stocking density. Managers applying AMP in semiarid rangelands should be cognisant that high stocking density can be associated with lower diet quality early in the growing season, which can compromise livestock gain responses.

Cyclodecanes, belonging to the class of aliphatic cycloalkanes, comprise non-aromatic carbon-atom rings. Within the 10-membered ring, cyclodecanes exhibit various isomers, characterized by different spatial arrangements of carbon atoms. Serving as model compounds in organic studies, cyclodecanes offer insights into the properties and reactivity of cyclic hydrocarbons. The chemistry of cyclodecane serves as a valuable foundation for understanding the behavior of more complex hydrocarbons. In this paper, we explore the potential probabilities of random cyclodecane chains

Investigations on the electronic, optical, thermoelectric and thermodynamic properties of quaternary coinage metal HgSeBr: a DFT study
Authors: Hariharan M , R D Eithiraj
Published: February 2024

In the present study, we examine the structural, electronic, optical, thermodynamic, and transport properties of CuHgSeBr, a mercury chalcogenide halide of coinage metals. Employing the FP-LAPW method via first principles calculations in the WIEN2k code, we investigate various properties including band structure, density of states, lattice constants, Debye temperature, and effective mass. CuHgSeBr manifests as an indirect bandgap semiconductor with a measure of 0.808 eV. Optical assessments using dielectric constants reveal its pronounced absorption of photons in the ultraviolet spectrum according to the ε
2 spectra. Furthermore, we present findings on electronic and lattice thermal conductivity, binding energy, and figure of merit. Notably, our calculations indicate a figure of merit of 0.226 at 300 K and 0.556 at 800 K, indicating CuHgSeBr’s potential as a valuable material for thermoelectric devices within industrial applications. Importantly, these detailed properties of CuHgSeBr have not been previously documented, underscoring the significance of this comprehensive research, which could guide future theoretical explorations aimed at identifying alternative materials with similarly intriguing properties.
Solar neutrino background in high-pressure gaseous 82SeF6 TPC neutrinoless double beta decay experiments*

Published: February 2024

In this study, the possibility of observing a solar neutrino background in a future neutrinoless double beta decay experiment using a high-pressure gaseous 82SeF6 TPC is investigated. Various contributions are simulated, and possible features that could be used for event classification are discussed; two types of backgrounds are identified. The rate of multi-site background events is approximately 0.63 events/(ton·yr) in a 30 keV ROI window. This background could be effectively reduced to less than 0.0001 events/(ton·yr) (95% C.L.) while maintaining a high signal efficiency of 93% by applying a selection based on the number of clusters and energy of the leading cluster. The rate of the single-electron background events is approximately 0.01 events/(ton·yr) in the ROI. Assuming a reduction factor of 10 for the single-electron background events obtained via the algorithms developed for radioactive background rejection, the total background induced by the solar neutrino would be 0.001 events/(ton·yr), which is sufficiently small for conducting ton-level experiments.

In response to the problems of poor stability and low efficiency in the transportation of temporary sludge in Shanghai Laogang, based on indoor experimental data, numerical simulation was used to predict the pressure drop characteristics of pipelines with different solid content, pipe diameters, and flow velocities, the numerical results show that at the same flow rate and pipe diameter, the pressure drop increases with the increase of solid content; The pressure drop gradually increases with the increase of flow rate at the same pipe diameter and solid content, and when the the flow state inside the pipe changes, there is a turning point in the flow rate pressure drop curve; At the same flow rate and solid content, the pressure drop decreases with the increase of pipe diameter. Combined with test for pipe pressure drop, the numerical method was verified, which provides guidance for the optimization and improvement of sludge transportation plans and the selection of transportation pumps.
