A novel BEM-DEM coupling in the time domain for simulating dynamic problems in continuous and discontinuous media

This work presents a novel scheme to couple the Boundary Element Method (BEM) and the Discrete Element Method (DEM) in the time domain. The DEM captures discontinuous material behaviour, such as fractured and granular media. However, applying the method to real-life applications embedded into infinite domains is challenging. The authors propose a solution to this challenge by coupling the DEM with the BEM. The capability of the BEM to model infinite domains accurately and efficiently, without the need for numerical artifices, makes it the perfect complement to the DEM. This study proposes a direct monolithic interface-based coupling method that resolves any incompatibilities between the two methods in two dimensions. The benchmark results show that the proposed methodology consistently produces results that align with analytical solutions. The final example in the paper showcases the full potential of this innovative methodology, where the DEM models a fracturing process, and the BEM evaluates its far-field effect.

An econometric analysis of price elasticity and demand factors in the global honey and honey-based beverage markets

The contemporary discourse on global commodity markets presents a myriad of compelling quandaries for scholars, policy-makers, and practitioners alike. Among these markets, since 2015 the global honey and honey-based beverage sector embodies unique economic characteristics and dynamics. While the market has experienced expansive growth in a plethora of jurisdictions, Kazakhstan remains out of focus of researchers. For this reason, we decided to undertake an exhaustive econometric analysis, scrutinizing the price elasticity of demand and various demand determinants in Kazakhstan’s honey and honey-based beverage markets. Utilizing longitudinal data spanning over a decade, this investigation employs advanced econometric methodologies - including but not restricted to Ordinary Least Squares (OLS) regressions, co-integration analyses, and error-correction models - to rigorously interrogate the price elasticity of demand for honey and honey-based beverages. The research encompasses multiple control variables like GDP per capita, consumer behavior, inflation rates, and population dynamics to create a multi-faceted econometric model capable of rendering nuanced insights. It incorporates both macroeconomic and microeconomic variables to delineate the symbiotic relationship between price elasticity and demand determinants such as consumer income, advertising impact, and price points of substitute and complementary goods. The analysis showed that the honey market in Kazakhstan is fundamentally oligopolistic, and the triumvirate of top producers collectively wield a 60% market control, leaving a residual 40% for the aggregation of small and medium enterprises. However, the findings unveil a complex web of economic variables influencing the price elasticity of demand in Kazakhstan’s honey markets. Most notably, the study elucidates that the price elasticity of demand for honey and honey-based beverages is highly inelastic in the short term but transitions towards being elastic in the long run, a phenomenon predominantly influenced by changes in consumer income and preferences. A 12.3% increase in exports from 2020 to 2021 implies an increasing global demand for Kazakhstani honey, and thus should be a focus for stakeholders to leverage for market expansion. An Export-to-Production Ratio at 26% indicates that roughly one-fourth of honey produced is assigned for the international markets. The average production cost per kilogram of honey in Kazakhstan was found lower compared to the global average. Remarkably, digitization has been adopted as a salient strategy for market development. The penetration of digital platforms for honey trading increased from 2% in 2012 to 18% in 2021. The research identifies complex interplay between exogenous variables like global market trends, geopolitical factors, and cultural shifts, contributing to a comprehensive understanding of the market dynamics at play. This article makes several seminal contributions to the academic dialogue surrounding the economics of honey markets. Firstly, it adds a new geographic focus by centering on Kazakhstan, an understudied yet burgeoning market in the global honey industry. Secondly, the rigorous econometric methodology employed contributes to the methodological lexicon of commodity market analyses. Finally, the complex approach, incorporating both economic theory and real-world market trends, paves the way for future studies and aids in the formulation of policy directives aimed at stabilizing price volatility in commodity markets.

Analisis Pengaruh Barang Substitusi dan Komplementer terhadap Fungsi Permintaan Cabai di Indonesia

The demand for red chilies grows yearly, in tandem with the increase in population or industries that use red chili as raw resources. This research aims to examine the effect of the determiner of chili demand in Indonesia and categorize them as substitutes or complementary goods. This research employs a quantitative descriptive design with secondary data analysis from the Central Bureau of Statistics. The variables studied were the average prices of red chilies, cayennes pepper, tomatoes, shallots, and garlic in Indonesia from 2010 to 2020. Cayenne pepper, tomato, garlic, and garlic prices significantly affect the 1% level, whereas the population does not affect red chili demand. The analytical tool used is the Cobb-Douglas model regression and elasticity analysis. The result shows that the impact of cayenne pepper, tomato, and garlic prices is directly proportional to the demand for red chilies. On the other hand, shallots significantly have an inverse impact on the demand for chilies. The high price of cayenne pepper, the cost of tomatoes, also the price of garlic will increase the demand for red chili, while the high price of shallots will reduce the need for red chili. According to price elasticity analysis, the cost of red chili is elastic to the demand for red chili in Indonesia. Cross-elasticity analysis shows that cayennes pepper, tomatoes, and garlic are substitutes, while shallots are complementary goods to red chilies.

Research on Sino-British Trade Efficiency and Potential

On the basis of analyzing the bilateral trade combination, export concentration and complementarity between China and the UK, a stochastic frontier gravity model is used to measure the trade efficiency and potential between China and the UK, and a realization path for China-UK trade cooperation is proposed. It is found that: the bilateral trade volume between China and the UK is steadily increasing, but the growth of UK exports to China is sluggish and the trade deficit is expanding year by year; the trade links between China and the UK are relatively loose, but there is a trend of strengthening; the trade products are more complementary and the types of trade complementary goods between the two countries do not overlap; but the export concentration is high. The trade potential between China and the UK is expanding year by year, reaching 224.9 billion USD by 2019; trade efficiency is steadily increasing, but is significantly constrained by tariff barriers and average turnaround time of imports, while financial and commercial liberalization can significantly improve the trade efficiency between the two countries. It is recommended to strengthen cooperation with the UK in the financial sector, expand imports of service products to the UK, and promote the construction of a free trade zone between the two countries at an appropriate time.

Skeletal Editing: Interconversion of Arenes and Heteroarenes

AbstractSkeletal editing involves making specific point‐changes to the core of a molecule through the selective insertion, deletion or exchange of atoms. It thus represents a potentially powerful strategy for the step‐economic modification of complex substrates and is a perfect complement to methods such as C−H functionalization that target the molecular periphery. Given their ubiquity in biologically active compounds, the ability to perform skeletal editing on – and therefore interconvert between – aromatic heterocycles is especially valuable. This review summarizes both recent and key historical examples of skeletal editing as applied to interconversion of aromatic rings; we anticipate that it will serve to highlight not only the innovative and enabling nature of current skeletal editing methods, but also the tremendous opportunities that still exist in the field.

Behavioral economic relationship between cannabis and cigarettes: Evidence from hypothetical purchase tasks.

In the United States (U.S), cannabis policies have been increasingly liberalized whereas tobacco policies have been increasingly stringent. Given the high prevalence of cannabis and tobacco dual use, there are concerns that a policy regulating one substance may unintendedly influence the other. This study examined the responsiveness of the demand for cannabis joints and cigarettes when price varied. The study included 338 adult participants (21+) who used both cannabis and tobacco and lived in one of the U.S. states with recreational cannabis legalized by the time of interview in 2019. They completed hypothetical purchase tasks to indicate the quantity desired of cannabis joints and cigarette packs 1) when only one substance was available with escalating prices and 2) when both substances were concurrently available with escalating prices of cannabis joints and a fixed price of cigarette packs. We estimated 1) the own-price elasticity of demand for each substance using nonlinear exponential demand model, and 2) the cross-price elasticity of demand at aggregate level using nonlinear exponential demand model and at individual level using log-linear demand model. The estimates for the rate of change of own-price elasticity (α) were 0.0011 (SE=0.000039, p<0.001) for cannabis joints and 0.00095 (SE=0.000037, p<0.001) for cigarette packs. The aggregate-level estimates of cross-price elasticity (I=13.032, SE=0.34, p<0.001; β=0.0029, SE=0.0021, p>0.05) suggest an independent relationship between the two substances. At individual level, 78.70% of the participants treated the two substances as independent, 17.46% as complements, and 3.85% as substitutes. For most adults who used both cannabis and tobacco in the U.S., cannabis joints and cigarettes had an independent relationship. Policies regulating the price of cannabis may not have large unintended consequences on cigarette use.

On the foundations of competitive search equilibrium with and without market makers

The literature offers two interpretations of competitive search equilibrium, one based on a Nash approach and the other on a market-maker approach. When each buyer visits only one seller, the two approaches are equivalent. However, when each buyer visits multiple sellers, this equivalence can break down. We present a model in which every buyer visits 2 sellers. A buyer who trades with one seller receives a value of s, while a buyer who trades with 2 sellers receives value 1. Letting s vary from 0 (perfect complements) to 1 (perfect substitutes) we characterize the competitive search equilibrium under the two interpretations. We show that for low values of s, the Nash and market-maker competitive search equilibria coincide, but the common equilibrium is inefficient. For intermediate values of s, the two equilibria again coincide and are efficient. Finally, for high values of s, the Nash and market-maker equilibria differ, and only the latter is efficient.

A Bayesian equilibrium for simultaneous first-price auctions for complementary goods and quasi-linear bids

&lt;p style='text-indent:20px;'&gt;This article shows a Symmetrical Bayesian Nash Equilibrium in a context of &lt;inline-formula&gt;&lt;tex-math id="M1"&gt;\begin{document}$ m $\end{document}&lt;/tex-math&gt;&lt;/inline-formula&gt; simultaneous first-price sealed-bid auctions and &lt;inline-formula&gt;&lt;tex-math id="M2"&gt;\begin{document}$ n $\end{document}&lt;/tex-math&gt;&lt;/inline-formula&gt; bidders for complementary goods. We consider that the individual valuations of the &lt;inline-formula&gt;&lt;tex-math id="M3"&gt;\begin{document}$ m $\end{document}&lt;/tex-math&gt;&lt;/inline-formula&gt; goods are common knowledge and identical among bidders and if the whole set of goods is gained, a private independent extra profit is obtained by the winner. For relaxing and solving the so-many mathematical complications involved in the general case we followed a classical methodology and proposed a particular bidding function that implies linear separability. Under this assumptions we obtain a Symmetric Bayesian Nash Equilibrium which functional form implies the classic quasi-linear property for bivariate functions. On addition, we compare the seller expected revenue between auctioning the complete set in one single first-price sealed-bid auction versus auctioning each item in &lt;inline-formula&gt;&lt;tex-math id="M4"&gt;\begin{document}$ m $\end{document}&lt;/tex-math&gt;&lt;/inline-formula&gt; simultaneous first-price sealed-bid auctions.&lt;/p&gt;

Low-carbon economic dispatch of integrated energy system considering carbon trading and integrated demand response with CCER

Under the background of ‘double carbon,’ to promote the transformation of generating units to new energy power generation in an integrated energy system and better realize carbon trading functions, the paper gives a carbon trading model considering CCER and a low carbon economy scheduling model considering joint demand response. First, consider the nationally certified voluntary emission reductions for wind power applications in the traditional carbon trading model, and improve the benefit of investment in renewable energy projects to strengthen the conversion of traditional energy structures to new energy structures while reducing the amount of carbon emissions in the system. Second, price-based and alternative responses are introduced on the user demand side to accurately model and optimize the load curve. The model is solved by using the CPLEX solution toolbox, and the correctness of the given model is proved by simulation.

China and Countries along the “Belt and Road”: Agricultural Trade Volatility Decomposition and Food Security

Agricultural products are essential for human survival, and strengthening agricultural trade cooperation between China and countries along the “Belt and Road” (B&amp;R) can promote food security, but there are few studies on bilateral trade fluctuation factors in the literature. This paper uses the modified multi-country multi-product CMS (constant market share) model and the two-country multi-product CMS model to decompose the fluctuation of agricultural trade between China and B&amp;R countries by stage, region, and agricultural product type. The results show that in recent years, in the fluctuation of China’s exports to B&amp;R countries, in overall agricultural products, the demand effect plays a major hindering role, accounting for −9.2%; in the region, Southeast Asia has the largest share of trade, which is mainly pulled by the joint demand effect, structural effect and competitiveness effect; in specific agricultural products, animal, fruit and vegetable, and food processing products are mainly pulled by competitiveness. In the fluctuation of B&amp;R countries’ export to China, in overall agricultural products, the demand effect pulls the largest share, accounting for 72.55%; in the region, Southeast Asia is mainly driven by the joint pull of demand effect, structural effect. and competitiveness effect; in specific agricultural products, animal, fruit and vegetable, and food processing products are mainly driven by the pull of demand effect. The findings of this paper can provide a basis for making decisions on food security cooperation between China and B&amp;R countries.

A study of micro-scale solder bump geometric shapes using minimizing energy approach for different solder materials

Demand for more interconnection joints between semiconductor devices can be realized with solder bump technology. Surface tension and density are usually material properties related factors that affect solder bump geometric shape. Therefore, to cope with this fast-changing microarchitecture design in semiconductor technology, a better understanding of the solder bump geometric shape is needed. This study used a static equilibrium force approach to integrate the surface tension and gravitational energy into the solder energy content. Surface Evolver software was used to perform calculations and deliver the final solder bump shape. Perfect agreement with less than 10 % comparison between previous studies and the current Surface Evolver results was found. According to statistical analysis using SPSS, the maximum width of solder shape is closely related to the surface tension. In contrast, the maximum standoff is highly correlated with the solder density. By changing the solder volume, the solder bump changes from standard flip-chip bump to Cu pillar bump with consistency in maximum width to maximum standoff height ratio of 1.5. This study shows that the bumping technology can produce various sizes of solder bumps to meet new electronic packaging requirements.

The New Small Wheel High Voltage Infrastructure

The ATLAS Muon Spectrometer is subjected to a series of upgrades in order to face the High Luminosity era of Phase-II. One of the main projects is the New Small Wheel (NSW), which has replaced the existing Small Wheel (SW), and is a perfect complement to the ATLAS Muon Spectrometer (MS) in the Endcap regions. The NSW is the combination of two prototype detector technologies, the small Thin Gap Chambers (sTGC) and the resistive Micromegas (MM). In order to operate smoothly the two technologies, a dedicated hardware infrastructure has been installed and modified accordingly based on the needs of each muon sub-system. In order to control and monitor the hardware for both technologies a Detector Control System (DCS) has been developed, following the architecture of the legacy Muon sub-systems. Aim of this work is the presentation of the development and implementation of these HV DCS systems under the Point 1 schema.

The Continuing Search for the Right Balance

Anesthesiologists are currently viewed as airway experts. Interestingly, advanced airway management were initially primarily performed to resuscitate victims of drowning and patients afflicted with diphtheria infection by non-anesthesiologists.1,2 In 1878, the first elective use of endotracheal intubation for anesthesia was performed by Dr. William Macewen, a Scottish surgeon, using an awake, digital blind intubation technique.1The invention of the Macintosh and Magill laryngoscope blades as well as the introduction of curare in the 1940’s facilitated tracheal intubation such that it already became a routine component of anesthetic management for major surgeries.2 Advancements involving flexible fiberoptic cables paved the way for flexible fiberoptic bronchoscope in the late 1960’s.3 Later on, the need for a wider angle of view to address difficult intubation cases gave birth to a variety of videolaryngoscopes in the 2000s.As early as 2004, there were already reports combining airway equipment to facilitate intubation.4 However, it was not until 2011 that Boet et al. coined the term “multimodal airway approach”.5 Since then, this practice has been explored further by anesthesiologists and is now included as an option in the American Society of Anesthesiologists difficult airway algorithm for both adult and pediatric patients.6The second article in this special issue described how a non-traditional combination of advanced airway equipment easily circumvented the difficulty posed by the initial sole airway equipment technique. Meanwhile, the third article incorporated a twist in the multimodal airway approach by employing two different techniques at different stages of the surgery.These two articles are particularly encouraging since an awake intubation for anticipated difficult airway is hardly applicable for the pediatric population. In addition, the combination described in the second article is reproducible in other parts of the country. The COVID-19 pandemic already created a rapid paradigm shift favoring the acceptance and availability of videolaryngoscopes in routine practice.7-9 Bonfils intubating fiberscope does not have a steep learning curve.10 It also requires less maintenance compared to a fiberoptic bronchoscope.Synergism is a pharmacologic principle that has long been used by anesthesiologists in maintaining homeostasis through the provision of “balanced anesthesia” and “multimodal analgesia”.11,12 The time has come to extend this concept to nonpharmacologic entities as well.As the field of anesthesiology continues to expand in coverage and complexity, the search continues for the perfect complement that will provide the right balance encompassing all elements.&#x0D; &#x0D; Evangeline K.

A mathematical model to predict the performance of the secondary clarifier of a municipal wastewater treatment plants

The activated sludge process for urban wastewater treatment has a high purification performance and reliability, especially for organic pollution. However, it presents several operational insufficiencies, such as sludge control, pollution degradation monitoring, and liquid/solid separation problems in the biological reactor/secondary clarifier couple. This paper presents an analysis of a secondary clarifier of wastewater treatment plant (WWTP) via an activated sludge, which could be used for the plant optimization. The models of the settling velocity and the secondary clarifier based on the sludge volume index (SVI) are addressed. We have proposed these models to explain the settling velocity activities and illustrate the relationship between the settleability characteristics. This research aims to develop and predict a one-dimensional model (1-D model) based on an exhaustive experimental study performed on the WWTP and online information, which are the total suspended solids (TSS), the SVI, and the influent characteristics. The results of the novel model for the secondary clarifiers integrating the empirical settling velocity equation presented a good agreement and a better fit with our experimental results, with an error of approximately zero. This simulation is a perfect complement to the management solution and the hydraulic overload monitoring of WWTPs.

Validating LA/AIDS model in the food market of Pakistan

The study aims to conduct a consumer demand analysis of the food market of Pakistan by estimating its own price and cross-price elasticities. This study also examines expenditure and income elasticities to show the influence of relative change in price, total expenditure, and income on the relative change in demanded quantities of the selected food products. The study takes meat, vegetables, fruits, and pulses as different food baskets and estimates income elasticities, including uncompensated (Marshallian) and compensated (Hicksian) own price and cross-price elasticities. The findings are concluded based on Marshallian elasticity as it provides more accurate images of substitutes and complements compared with Hicksian elasticity. The study applies the Linear Approximate Almost Ideal Demand System model to estimate the results by acquiring data from a household integrated economic survey of Pakistan from 2018 to 2019. The findings of expenditure elasticity (uncompensated own price elasticity) reveal that vegetables and pulses are normal (inelastic) goods, whereas meat and fruits are luxury (elastic) goods. The results of uncompensated cross-price elasticities reveal that vegetables and meat, and vegetables and fruits are substitutable commodities. In addition, pulses and vegetables, and pulses and meat are complementary goods. The study suggests fruitful implications for food policymakers.

The Effects of Photo Decoration Cues on Online Consumers’ Affective Responses

This study refines three decoration cues from the photos in the online grocery store which enable consumer to experience grocery with affective responses. Three cues on consumers’ affective perception, attitudes as well as behavioral intention were examined in a laboratory experiment. The experiment results show that (1) both reflective surface and complementary goods layout lead to visual appeal and shopping enjoyment; (2) contrast color usage positively impacts on visual appeal while does not significantly affect shopping enjoyment; (3) consumers’ affective responses positively impact attitudes toward product and store which in turn lead to purchase intention and store loyalty. Implications for research and practice are discussed.

What Explains Smartwatch Adoption? A comparative study of South Korea and Indonesia

Identifying factors that influence consumers’ intentions to adopt a smartwatch has become a major research interest in marketing literature, yet little is known about it in dissimilar cultural settings. The current research employs a comparative study of South Korea and Indonesia, which differ in location and cultural heritage, smartwatch penetration rate, geographic size, level of income, and developmental stage as a country. An extended model of TAM is proposed, and PLS-SEM is employed to test the model on data collected from 262 respondents. The findings indicate that complementary goods and healthtology have positive influences on perceived usefulness and visibility has a positive influence on social image; these, together with perceived price value, lead to the behavioral intention to adopt a smartwatch in both countries. Perceived cost was only significant for Indonesia. Theoretical contributions and practical implications are further discussed.

Is there a need for a new journal metric? Correlations between JCR Impact Factor metrics and the Journal Citation Indicator—JCI

• The JCI has similar properties to the JIF and the 5-Year JIF. • The JCI indicator has very significant correlations with the JIF and the 5-year JIF. • The JCI can be very useful for ESCI and arts and humanities journals. In 2021, Clarivate published a new version of the Journal Citation Reports (JCR) including a new indicator. The Journal Citation Indicator (JCI) is a new field-normalized metric at journal-level, which is calculated by averaging the Category Normalized Citation Impact (CNCI) of the journal's articles and reviews published in the preceding three-year period. Unlike the Journal Impact Factor (JIF), it is also calculated for the journals of the Arts & Humanities Citation Index (AHCI) and the Emerging Sources Citation Index (ESCI), which are now included in the JCR. To better understand this new indicator, this article analyses its main statistical characteristics in comparison with the other JCR indicators using all JCR journals and categories. The results highlight the similarities between the JCI and JIF, with a high Pearson correlation (0.853) and a similar distribution. This correlation is also high and homogeneous in the different categories, both for Science and Social Sciences. The JCI is therefore a perfect complement to the JIF, as well as representing an alternative to resolve the well-known problems of the JCR.
