В работе исследованы аналитические свойства дисперсионных соотношений уравнения внутренних гравитационных волн с модельными и произвольными распределениями частоты плавучести. Для аналитического решения задачи использовано модельное распределение частоты плавучести, которое применяется в прикладных океанологических расчетах при наличии сезонного термоклина. Получены неявные формы дисперсионных зависимостей, которые выражаются через функцию Бесселя действительного индекса. Для волновых чисел отличных от нуля предложен асимптотический метод исследования дисперсионного соотношения, основанный на построении равномерных асимптотик функций Бесселя для больших значений действительного индекса и аргумента, которые выражаются через функции Эйри. Для произвольного распределения частоты плавучести с помощью метода возмущений и метода ВКБ получены асимптотические представления дисперсионных соотношений при малых волновых числах. Построенные в работе решения позволяют в дальнейшем рассчитывать амплитудно-фазовые характеристики полей внутренних гравитационных волн с модельными и произвольными распределениями частоты плавучести.

E-prescribing by midwives: The situation in Greece
Authors: Maria Tigka  , Aikaterini Lykeridou  , Dimitra Metallinou
Published: July 2023

Electronic prescribing (e-prescribing) offers numerous benefits but has also disadvantages. The use of e-prescribing is becoming increasingly widespread worldwide but e-prescribing for midwives may vary from country to country. Regulations in Greece have defined the right of midwives to prescribe specific medicines and diagnostic tests since 1989. However, several years later, in 2019, legislation provided for the regulation of e-prescription for midwives. Midwives play a crucial role in the healthcare system, especially in the care of women and neonates. They are trained professionals who provide a range of services, including antenatal care and can help prevent and treat health problems that may arise during a woman's lifetime. It is therefore of utmost importance to empower midwives with prescribing capabilities which will facilitate the role of Primary Health Care.
Performance Study of AODV, GRP and OSPFv3 MANET Routing Protocols Using OPNET Modeler
Authors: Jassim Sabbar Insaif
Published: July 2023

A Mobile Ad hoc Network (MANET) is a collection of mobile nodes, that forms on the fly a temporary wireless multi-hop network in a self-organizing way, without relying on any established infrastructure. In MANET, a pair of nodes exchange messages either over a direct wireless link, or over a sequence of wireless links including one or more intermediate nodes. For this purpose, an efficient routing protocol is required. This paper introduced performance study of three of MANET protocols (AODV, GRP and OSPFv3). This study was one of the newer studies because wireless communication played an important role in today’s application and the field of mobile ad hoc network becomes very popular for the researchers in the last years. This study was done using OPNET Modeler v14.5 and the comparison between the protocols was done in terms of throughput, routing traffic received, traffic sent, load and delay with increased number of mobile nodes from 10, 25 and 50 mobile nodes. The results showed that AODV (reactive routing protocol) was better in delay and had smaller load and smaller throughput than GRP (reactive and proactive routing protocols) and OSPFv3 (proactive routing protocols).
Public support for the cordon sanitaire: Descriptive evidence from Spain
Authors: Turnbull-Dugarte Stuart James
Published: July 2023

Final - open access - version available at: https://doi.org/10.1177/13540688241246141 Reactions to the rise of far-right parties that advocate democratic backsliding, and the dilution of socially liberal democratic norms present a dilemma for existing political parties. How should existing political parties respond to this challenge? A commonly adopted strategy is to apply a \textit{cordon sanitaire} which excludes radical right-wing challengers from the government-forming process. Do voters support this policy? Leveraging data from Spain -- where the mainstream right has accommodated the radical right-wing party, VOX, via numerous governing coalitions -- I rely on individual citizens’ views on how parties should respond to rise of the far-right party, to answer this question. Empirically, I find very low-level support for the cordon sanitaire in Spain. Indeed, the median position of the electorate, regardless of their ideological position, is to treat the party just like any other. These results are not conditioned by the propensity of individuals to identify VOX as indeed being a “radical right” party. These descriptive findings suggest that whilst radical right-wing parties may present an inimical threat to democratic norms, citizens do not necessarily view the means of squashing this threat to be one of strategic exclusion. This likely explains why the mainstream right has been able to institutionalise VOX as a political ally: where strategic exclusion is not expected, the mainstream right need not fear violating an expectation that does not exist.
Imprecise wording in academic articles routinely overstates the validity of research findings
Authors: Greene Danyelle , Dolnicar Sara
Published: July 2023

Imprecise wording in research articles can mislead readers to think that the findings are more powerful than they are. We empirically investigate how common it is for scholars to include statements in their articles which fail to accurately reflect the research design they used. We find that inaccurate statements are made in nearly half (47%) of all 2022 articles under investigation. Concerningly, the sections where such statements occur most frequently are the title, the discussion section, and the abstract – the very sections that are read most, especially by people who are only skimming through the literature. As a result, the risk of misinterpreting and misquoting findings is high, as is the risk that industry may adopt measures developed by scholars to change behaviour, even if there is no empirical evidence that such interventions indeed do change behaviour.
What the Climate Movement’s Debate about Disruption Gets Wrong
Authors: Thomas-Walters Laura , Young Kevin A.
Published: July 2023

The recent debate about whether climate activists should employ disruptive tactics tends to conflate all forms of disruption. The debate typically focuses on the public’s reaction to protesters, yet the more important question is whether a given tactic imposes disruption on elite decision makers. Most analysts fail to specify what approaches are most disruptive of elite interests and which elite institutions the movement should target. They also often misinterpret the lessons of historical social movements. We reconsider one of those movements, the Birmingham civil rights campaign of 1963, in light of the current strategic debate. We argue that disruption is necessary, but that not all “disruptive” strategies are equally effective. In particular, we advocate a strategy that can impose sustained and escalating costs on the elite sectors that can force politicians to confront the climate emergency. Priority targets include financial institutions that fund and underwrite fossil fuels as well as corporations, universities, pension funds, and other institutions that consume and invest in fossil fuels.

Authors: Karki Subash , Sapkota Biswash
Published: July 2023

Introduction: Buddleja asiatica is an upright, evergreen shrub of the Loganiaceae family that can reach up to 1 to 8 meters tall and found between 300-2000 meters height in Nepal.
Objectives: The objectives of this study are to assess the antibacterial, antioxidant, and analgesic properties of Buddleja asiatica aerial component.
Methods: A typical chemical test was outlined to conduct the phytochemical analysis. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radicals scavenging experiment was used to quantitatively quantify the antioxidant activity of the methanolic extract. By using the well diffusion method, the antibacterial activity was assessed against Escherichia coli and Staphylococcus aureus. Swiss albino mice were utilized to test the analgesic efficacy of the extracts using the acetic acid-induced writhing method and the tail flick method.
Results: The phytochemical screening identified the presence of reducing sugars, tannin, phenol, alkaloid, glycoside, and flavonoids. With a zone of inhibition of 19 mm, antibacterial efficacy against Staphylococcus aureus was demonstrated. The extract demonstrated scavenging potential in the DPPH free radical scavenging experiment, with an IC50 value of 123.68 μg/mL. At 600, 800, and 1000 mg/kg, the acetic acid-induced writhing method showed a significant (P < 0.05) analgesic effect. The tail flick approach, which evaluates the pain reaction time, also produced similar results.
Conclusion: Different secondary metabolites contained in Buddleja asiatica were found in the methanolic extract, and these secondary metabolites were determined to be physiologically active in terms of good antioxidant, analgesic, and antibacterial activities.

Modelling and Optimization of Carbon Steel Corrosion in CO2 Containing Oilfield Produced Water in Presence of HAc
Authors: Yaro Aprael S. , Rashid Khalid H.
Published: July 2023

Previously, many empirical models have been used to predict corrosion rates under different CO2 corrosion parameters conditions. Most of these models did not predict the corrosion rate exactly, besides it determined effects of variables by holding some variables constant and changing the values of other variables to obtain the regression model. As a result the experiments will be large and cost too much. In this paper response surface methodology (RSM) was proposed to optimize the experiments and reduce the experimental running. The experiments studied effects of temperature (40 – 60 °C), pH (3-5), acetic acid (HAc) concentration (1000-3000 ppm) and rotation speed (1000-1500 rpm) on CO2 corrosion performance of the regression model calculated by RSM. The experiments were conducted in saturated solution of CO2 with 3.5 % NaCl solution. STATISTICA program version 10 was used for data analysis. In conclusion a quadratic model is proposed to predict the effect of mentioned variables in CO2 environment.
Prediction of Shear Wave velocity for carbonate rocks
Authors: Al-Kattan Wafa M.
Published: July 2023

In many oil fields only the BHC logs (borehole compensated sonic tool) are available to provide interval transit time (Δtp), the reciprocal of compressional wave velocity VP.

   To calculate the rock elastic or inelastic properties, to detect gas-bearing formations, the shear wave velocity VS is needed. Also VS is useful in fluid identification and matrix mineral identification.

   Because of the lack of wells with shear wave velocity data, so many empirical models have been developed to predict the shear wave velocity from compressional wave velocity. Some are mathematical models others used the multiple regression method and neural network technique.

   In this study a number of empirical models were considered to predict VS from VP. The models had been correlated and a general equation, based on statistical method, was established for carbonate rocks.

   The proposed equation, then, was examined using log data and good results observed.

Published: July 2023

Indirect electrochemical oxidation of phenol and its derivatives was investigated by using MnO2 rotating cylinder electrode. Taguchi experimental design method was employed to find the best conditions for the removal efficiency of phenol and its derivatives generated during the process. Two main parameters were investigated, current density (C.D.) and electrolysis time. The removal efficiency was considered as a response for the phenol and other organics removal. An orthogonal array L16, the signal to noise (S/N) ratio, and the analysis of variance were used to test the effect of designated process factors and their levels on the performance of phenol and other organics removal efficiency. The results showed that the current density has the higher influence on performance of organics removal while the electrolysis time has the lower impact on the removal performance. Multiple regressions was utilized to acquire the equation that describes the process and the predicted equation has a correlation coefficient (R2) equal to 98.77%. The best conditions were found to get higher removal efficiency. Removal efficiency higher than 95% can be obtained in the range of C.D. of 96-100 mA/cm2 and electrolysis time of 3.2 to 5 h. The behavior of the chemical oxygen demand (COD) mineralization denotes to a zero order reaction and the rate of reaction controlled by active chlorine reaction not by mass transfer of phenol towards the anode.

Authors: Assi Amel habeeb
Published: July 2023

Of the many functions that are performed by the drilling fluid, the most important is to transport cuttings from the bit up the annulus to the surface. Various drilling fluid have been widely used in the oil industry to improve lifting capacity. In this study, three mud type have been used which they are, oil base mud, X-anthan polymer and a mixture of CMC and bentonite ,by using Carrying Capacity Index  calculation (CCI) , the Xanthan  gave good values of CCI than other studied drilling fluid. By using Sifferman chart and field data from well in south of Iraq and API equation to find cutting concentration in the annulus, The results showed that the used of thick mud increase the lifting capacity and decrease volumetric drill cuttings in the annulus but the using thin mud lead to decrease lifting capacity and increase volumetric drill cuttings in the annulus .The results show that the mud viscosity and flow rate have important role in hole cleaning. Also, the effect of   annulus velocity and flow pattern on cutting transport ratio is studied by using field data. The effect of cutting size and OD of drill pipe is also studied. Cutting size is one of the parameters that influence the hole cleaning; large size cutting makes the hole cleaning more difficult. The reducing of annular size of hole by increasing the OD of drill pipe lead to increasing the annular velocity.

Teaching Data Joins: A Conceptual Approach Using SQL, Alteryx, and Tableau
Authors: Li Jie , Lee Lorraine
Published: July 2023

The many ways of joining data can be confusing for beginning, or even intermediate, data analytics students. Several accounting information system textbooks cover SQL and joins, but few supplemental resources exist that can reinforce and clarify join concepts. In this paper, we use a multi-tool approach in a three-part assignment for teaching data joins using three different software tools. We use four different join types (INNER JOIN, LEFT OUTER JOIN, RIGHT OUTER JOIN, and FULL OUTER JOIN) in Microsoft Access, Alteryx, and Tableau. We further demonstrate how the Tableau data model, using separate logical and physical layers, implements the various join types depending on the data needs of a particular visualization. Overall, thus three-part assignment can help students develop a comprehensive understanding of joins and how to implement them in widely-used software tools. The assignment also gives students practice in selecting, using, and validating joins in data analytics.

Published: July 2023

Solar photovoltaic panels are very widely used these days across the country. Their usage is also being encouraged by the central government and there are many subsidies in place as well. The tilt angle of the solar photovoltaic panel with the horizontal along with module orientation determines the transformation of energy into electricity. The optimum tilt angle for solar photovoltaic panels is considered for incident annual solar energy, this angle is usually kept unchanged for the year-round cycle. In this research work, we examine the optimum tilt angles of panels for the incident energy over panels on an annual and seasonal basis in combination with the shading effect of these panels over rooftops of Delhi (latitude 28.7° N), Nagpur (latitude 21.15° N) and Ahmedabad (latitude 23.02° N). Solar radiation data for the investigation purpose has been classified under 3 seasons, i.e., summer (May, June, July, August), winter (November, December, January, February) and equinoxes (March, April, September, October). It is observed that when panels are arranged facing down south and adjusted seasonally for optimum tilt angle; on an annual basis, they generate higher electrical energy and, in the summer, cast a larger shadow; in the winter, cast a smaller shadow as compared to panels which have fixed tilt throughout the year. This arrangement helps in reducing the solar heat flux via the roof in summer and increasing it in winter, thus, favourably affecting air conditioning load levelling in the structure.

High-rate anaerobic digesters are of great concern these days—due to their high loading capacity, reduced carbon footprints and lower sludge production. Among them, the most preferred is the upflow anaerobic sludge blanket (UASB) reactor. However, there are still unresolved issues that inhibit the widespread of this technology. To start with the granular sludge bed fostering the microflora forms the prime seat in the working of UASB reactors. These microflora have a predominant role in the treatment of wastewater, hence the factors governing their growth, survival, and distribution are to be studied. Thus it seemed as due important to analyse the granular sludge for its particle size, particle density, and microfilm characteristics, to enhance the reactor’s efficiency. This has made scientists across the world put an eye on factors that shape the granules and how the granules contribute to wastewater treatment. The state-of-the-art is presented in this study.

Authors: Shekhar Sumant , Garg Manoj Chandra , Verma Vinod Kumar , Jindal Tanu
Published: July 2023

MSW management directly impacts public health and quality of life in cities. Unfortunately, solid waste management is generally considered the exclusive domain of government. However, since residents are the primary generators of municipal solid waste, there is virtually worldwide consensus among all major stakeholders that citizens must actively participate in this process. The need for more awareness among citizens and better communication between the government and citizens severely hampers this. Therefore, specific government initiatives are needed to bridge this communication gap. With this in mind, this study presents a structure for developing a waste management transmission process that recognises the public’s leading issues and the best strategies for raising public awareness. The results indicate that people’s attitudes toward solid waste could be more satisfactory. The government should also involve the public in managing regional and local waste problems.

This research aims to remove the toxic and dangerous Eosin B (EB) dye by using one of the adsorption processes based on environmentally friendly surfaces prepared in a natural way without chemical activation as low-cost agricultural waste, like pomegranate peels, banana peels, clove sticks and eggshells. Several factors were used that affect the adsorption process. These materials have several advantages such as eco-friendly and having a high surface area to enhance the removal of pollutants. The studied parameter includes the contact time of an equilibrium EB dye which was achieved within 60 min, effect of different initial concentrations of EB dye (10-60 mg/L). The concentration of EB dye was found to increase with the adsorption efficiency (Qe mg/g) while the removal percentage E% decreased, whereas effect of adsorbents dosage was found to increase when the removal percentage (E%) of Eosin B dye increased from 45.55-88.99%, 40.67-82.23% (32.21-77.32%), and (25.34-75.22%). However, the adsorption capacity decreased from 95.66 to 43.43 mg/g, 92.34 to 40.11 mg/g, 90.32 to 37.11mg/g and 91.22-40.3 mg/g when the mass adsorbents of pomegranate peels, banana peels, clove sticks, and egg shells increased from 0.025 to 2 gm in the same order. Also, adsorption isotherms were studied and they obeyed the Freundlich isotherm models.
An advanced YOLOv3 method for small object detection
Authors: Liu Baokai , He Fengjie , Du Shiqiang , Li Jiacheng , Liu Wenjie
Published: July 2023

Small object detection has important application value in the fields of autonomous driving and drone scene analysis. As one of the most advanced object detection algorithms, YOLOv3 suffers some challenges when detecting small objects, such as the problem of detection failure of small objects and occluded objects. To solve these problems, an improved YOLOv3 algorithm for small object detection is proposed. In the proposed method, the dilated convolutions mish (DCM) module is introduced into the backbone network of YOLOv3 to improve the feature expression ability by fusing the feature maps of different receptive fields. In the neck network of YOLOv3, the convolutional block attention module (CBAM) and multi-scale fusion module are introduced to select the important information for small object detection in the shallow network, suppress the uncritical information, and use the fusion module to fuse the feature maps of different scales, so as to improve the detection accuracy of the algorithm. In addition, the Soft-NMS and Complete-IOU (ClOU) strategies are applied to candidate frame screening, which improves the accuracy of the algorithm for the detection of occluded objects. The experimental results on MS COCO2017, VOC2007, VOC2012 datasets and the ablation experiments on MS COCO2017 datasets demonstrate the effectiveness of the proposed method.The experimental results show that the proposed method achieves better accuracy in small object detection than the original YOLOv3 model.
Fuzzy cross-efficiency evaluation based on prospect theory and regret theory
Authors: Fan Jianping , Tian Ge , Wu Meiqin
Published: July 2023

Cross-efficiency in data envelopment analysis is widely used in production as an evaluation method that includes input and output indicators and allows for self-evaluation and mutual evaluation of decision making units (DMUs). However, as the application scenarios continue to expand, the traditional methods gradually fail to meet the needs. Many researchers have proposed improved methods and made great progress in weight determination, but the existing studies still have shortcomings in considering the psychological behavior of decision makers (DMs) and there is still relatively little research on cross-efficiency in fuzzy environments. In this paper, we proposed a method to apply CRITIC to determine weights and introduce both prospect theory and regret theory into the evaluation method of cross-efficiency to obtain the prospect cross-efficiency matrix and regret cross-efficiency matrix respectively, and then applied the Pythagorean hesitant fuzzy operator to aggregate them to achieve the ranking of DMUs through the fraction function. This largely takes into account the subjective preference and regret avoidance psychology of DMs. The applicability of this paper’s method is also verified through an example of shopping for a new energy vehicle. Finally, the effectiveness of this paper’s method is verified by comparing three traditional methods with this paper’s method, which provides an effective method for considering risk preferences in the decision-making process.

Silver tungstate (α-Ag2WO4), silver molybdate (β-Ag2MoO4), and silver vanadate (α-AgVO3) microcrystals have shown interesting antimicrobial properties. However, their biocompatibility is not yet fully understood. Cytotoxicity and the inflammatory response of silver-containing microcrystals were analyzed in THP-1 and THP-1 differentiated as macrophage-like cells, with the alamarBlue™ assay, flow cytometry, confocal microscopy, and ELISA. The present investigation also evaluated redox signaling and the production of cytokines (TNFα, IL-1β, IL-6, and IL-8) and matrix metalloproteinases (MMP-8 and -9). The results showed that α-AgVO3 (3.9 μg/mL) did not affect cell viability (p > 0.05). α-Ag2WO4 (7.81 μg/mL), β-Ag2MoO4 (15.62 μg/mL), and α-AgVO3 (15.62 μg/mL) slightly decreased cell viability (p ≤ 0.003). All silver-containing microcrystals induced the production of O2− and this effect was mitigated by Reactive Oxygen Species (ROS) scavenger and N-acetylcysteine (NAC). TNFα, IL-6 and IL-1β were not detected in THP-1 cells, while their production was either lower (p ≤ 0.0321) or similar to the control group (p ≥ 0.1048) for macrophage-like cells. The production of IL-8 by both cellular phenotypes was similar to the control group (p ≥ 0.3570). The release of MMP-8 was not detected in any condition in THP-1 cells. Although MMP-9 was released by THP-1 cells exposed to α-AgVO3 (3.9 μg/mL), no significant difference was found with control (p = 0.7). Regarding macrophage-like cells, the release of MMP-8 and -9 decreased in the presence of all microcrystals (p ≤ 0.010). Overall, the present work shows a promising biocompatibility profile of, α-Ag2WO4, β-Ag2MoO4, and α-AgVO3 microcrystals.

Published: July 2023

Background: Pediatric gliomas (PGs) are highly aggressive and predominantly occur in young children. In pediatric gliomas, abnormal expression of Homeobox (HOX) family genes (HFGs) has been observed and is associated with the development and progression of the disease. Studies have found that overexpression or underexpression of certain HOX genes is linked to the occurrence and prognosis of gliomas. This aberrant expression may contribute to the dysregulation of important pathological processes such as cell proliferation, differentiation, and metastasis. This study aimed to propose a novel HOX-related signature to predict patients’ prognosis and immune infiltrate characteristics in PGs.

Methods: The data of PGs obtained from publicly available databases were utilized to reveal the relationship among abnormal expression of HOX family genes (HFGs), prognosis, tumor immune infiltration, clinical features, and genomic features in PGs. The HFGs were utilized to identify heterogeneous subtypes using consensus clustering. Then random forest-supervised classification algorithm and nearest shrunken centroid algorithm were performed to develop a prognostic signature in the training set. Finally, the signature was validated in an internal testing set and an external independent cohort.

Results: Firstly, we identified HFGs significantly differentially expressed in PGs compared to normal tissues. The individuals with PGs were then divided into two heterogeneous subtypes (HOX-SI and HOX-SII) based on HFGs expression profiles. HOX-SII showed higher total mutation counts, lower immune infiltration, and worse prognosis than HOX-SI. Then, we constructed a HOX-related gene signature (including HOXA6, HOXC4, HOXC5, HOXC6, and HOXA-AS3) based on the cluster for subtype prediction utilizing random forest supervised classification and nearest shrunken centroid algorithm. The signature was revealed to be an independent prognostic factor for patients with PGs by multivariable Cox regression analysis.

Conclusion: Our study provides a novel method for the prognosis classification of PGs. The findings also suggest that the HOX-related signature is a new biomarker for the diagnosis and prognosis of patients with PGs, allowing for more accurate survival prediction.

Published: July 2023

In this study, a novel fluidic oscillator suitable for use as a key component of a flow control device is proposed and investigated through numerical simulations. The new layout adds resonators to a typical fluidic oscillator with dual feedback channels, and the length of the feedback loop is designed to be adjustable. This fluidic oscillator with movable feedback channels and resonators can generate a jet with an adjustable frequency, and it has smaller total pressure loss than the baseline model. Numerical results show that the movement of the feedback channels regulates the degree of coupling between the feedback channels and resonators to generate different orders of jet frequencies. This self-excited fluidic oscillator with adjustable jet frequency is more adaptive than typical designs when dealing with complex flow separation conditions, and it will be more stable because the frequency adjustment requires neither high-frequency movable mechanisms nor external energy input. Moreover, the frequency switching phenomenon is observed in special cases, which may help improve the efficiency of the compressor blades with a drastically changed dominant frequency under off-design conditions or with multiple dominant frequencies, such as tip leakage flow and shock–boundary layer interaction.

Published: July 2023

Urbanization can drive economic growth, but it may harm the quality of the urban environment if improper actions are performed. Environmental issues resulting from urbanization can negatively impact the health of city dwellers. Therefore, studying air pollutants is crucial to urban development. In this study, we focus on Xiamen and examine the distribution patterns of urban air pollutants over an extended period of time. The goal is to enhance Xiamen’s air quality and bridge the research gap in long-term air quality studies specific to Xiamen. Based on monitoring data from 2014 to 2021 spanning 8 years, this study analyzed the trends in atmospheric particulate matter (PM: PM10, PM2.5) and their relationship with meteorological factors (such as wind speed: WS, temperature: T, dew point temperature: DPT, height of the cloud ceiling: HCC) and the concentrations of other pollutants (SO2, NO2, CO, and O3). The results indicated that (1) The high air quality in Xiamen with the lowest PM values observed during summer and the highest during winter; NO2 and SO2 concentrations showed similar trends to PM, while O3 and CO concentrations varied differently. (2) In general, the maximum daily PM concentration was observed in the evening and early morning, while the lowest value appeared at noon. The concentrations of PMs were positively correlated with other pollutants, while T, WS, HCC (cloud cover of more than 70%), and DPT were negatively correlated with PM concentrations. (3) There exists a relationship between concentrations of atmospheric particulate matter, atmospheric pollutants, and meteorological factors. The wind direction had varying effects on PM concentration, with PM2.5 and PM10 concentrations showing consistent trends and higher concentrations of PMs observed when winds blew from the west, southeast, and northeast. This study also provides a summary of strategies for addressing different air pollutant distribution characteristics. The purpose of this study is to analyze the distribution patterns of air pollutants in Xiamen and provide valuable insights for improving the city’s air quality.

Published: July 2023

Cell-cell communication (CCC) inference has become a routine task in single-cell data analysis. Many computational tools are developed for this purpose. However, the robustness of existing CCC methods remains underexplored. We develop a user-friendly tool, RobustCCC, to facilitate the robustness evaluation of CCC methods with respect to three perspectives, including replicated data, transcriptomic data noise and prior knowledge noise. RobustCCC currently integrates 14 state-of-the-art CCC methods and 6 simulated single-cell transcriptomics datasets to generate robustness evaluation reports in tabular form for easy interpretation. We find that these methods exhibit substantially different robustness performances using different simulation datasets, implying a strong impact of the input data on resulting CCC patterns. In summary, RobustCCC represents a scalable tool that can easily integrate more CCC methods, more single-cell datasets from different species (e.g., mouse and human) to provide guidance in selecting methods for identification of consistent and stable CCC patterns in tissue microenvironments.
