Published: June 2022

Coronary microcirculation has a fundamental role in the regulation of coronary blood flow in response to cardiac requirements, which has aroused wide concerns in basic science and clinical cardiovascular research. A comprehensive understanding of the development status of this field is conducive to its improvement. We aimed to analyze coronary microcirculation-associated literatures over 30 years and provide insightful information on the evolutionary path, frontier research hotspots, and future developmental trends. Publications were retrieved from the Web of Science Core Collection (WoSCC). VOSviewer was used to perform co-occurrence analyses for countries/regions, institutions, and authors and to generate visualized collaboration network maps. CiteSpace was used to analyze the raw data and to visualize the knowledge map derived from reference co-citation analysis, burst references, and keywords detection. The collected 11,718 publications showed an annually increasing trend. The United States and Harvard University ranked at the top among all the countries and institutions. The majority of articles were published in Circulation, and it also was the most co-cited journal. Co-citation analysis, burst detection, and alluvial flow map revealed that thematic hotspots and frontiers on coronary microcirculation were focused on coronary microvascular dysfunction, magnetic resonance imaging, fractional flow reserve, STEMI, and heart failure. Additionally, keywords burst showed that the prognostic value and management were current knowledge gaps and future directions. Coronary microcirculation presented a research hotspot relevant wide spectrum of clinical cardiovascular diseases. The definite diagnostics and prognostics are particularly valued. The protection of cardiovascular events that influence clinical outcomes should be an insightful concern in the future. Multidisciplinary collaborations will provide significant advances for the development of coronary microcirculation.

Published: June 2022

The mannose-6-phosphate (M6P) biosynthetic pathway for lysosome biogenesis has been studied for decades and is considered a well-understood topic. However, whether this pathway is regulated remains an open question. In a genome-wide CRISPR/Cas9 knockout screen, we discovered TMEM251 as the first regulator of the M6P modification. Deleting TMEM251 caused mistargeting of most lysosomal enzymes due to their loss of M6P modification and accumulation of numerous undigested materials. We further demonstrated that TMEM251 localizes to the Golgi and is required for the cleavage and activation of GNPT, the enzyme that catalyzes M6P modification. In zebrafish, TMEM251 deletion leads to severe developmental defects including heart edema and skeletal dysplasia, which phenocopies Mucolipidosis Type II. Our discovery provides a mechanism for the newly discovered human disease caused by TMEM251 mutations. We name TMEM251 as GNPTAB cleavage and activation factor (GCAF) and its related disease as Mucolipidosis Type V.

Temporal lobe epilepsy is the most drug-resistant type with the highest incidence among the other focal epilepsies. Metabolic manipulations are of great interest among others, glycolysis inhibitors like 2-deoxy d-glucose (2-DG) being the most promising intervention. Here, we sought to investigate the effects of 2-DG treatment on cellular and circuit level electrophysiological properties using patch-clamp and local field potentials recordings and behavioral alterations such as depression, anxiety-like behaviors, and changes in nitric oxide signaling in the intrahippocampal kainic acid model. We found that epileptic animals were less anxious, more depressed, with more locomotion activity. Interestingly, by masking the effect of increased locomotor activity on the parameters of the zero-maze test, no altered anxiety-like behavior was noted in epileptic animals. However, 2-DG could partially reverse the behavioral changes induced by kainic acid. The findings also showed that 2-DG treatment partially suppresses cellular level alterations while failing to reverse circuit-level changes resulting from kainic acid injection. Analysis of NADPH-diaphorase positive neurons in the CA1 area of the hippocampus revealed that the number of positive neurons was significantly reduced in dorsal CA1 of the epileptic animals and 2-DG treatment did not affect the diminishing effect of kainic acid on NADPH-d+ neurons in the CA1 area. In the control group receiving 2-DG, however, an augmented NADPH-d+ cell number was noted. These data suggest that 2-DG cannot suppress epileptiform activity at the circuit-level in this model of epilepsy and therefore, may fail to control the seizures in temporal lobe epilepsy cases.
Evidence of a possible local extinction in the north of Chile? The case of the tenebrionid Praocis (Orthogonoderes) insularis Kulzer, 1958 (Coleoptera: Tenebrionidae)

Published: June 2022

There are numerous causes of the extinction of insects, including the loss, degradation, and fragmentation of habitats, phenomena that have increased during the Anthropocene. Here we examine the current status of Praocis (Orthogonoderes) insularis Kulzer, 1958 (Coleoptera: Tenebrionidae), an endemic element of the Chilean coastal desert described in 1958. This species has been recorded only on Guacolda Island (Atacama Region, Chile), whose insular ecosystem has been drastically modified by coastal mining interventions. This article includes a redescription of the species, a habitus picture of the species, a map of the sites where we have searched for Praocis (Orthogonoderes) insularis in the past 15 years, and current photos of its habitat on Guacolda Island.Implications for insect conservation We provide evidence regarding the local extinction of this species in an environment that has been greatly modified in the past 60 years. We also discuss the modifications to its habitat and the causes of a possible first local extinction of an insect in Chile.
In-silico design of a multi-epitope recombinant vaccine against SARS-CoV-2 targeting the receptor-binding domain
Authors: Pande Harshawardhan
Published: June 2022

The COVID-19 pandemic caused by the SARS-CoV-2 virus has posed several challenges in the development of efficacious epitope-based vaccines. While multiple bioinformatic studies have attempted to predict epitopes, they have focused on the whole spike protein without considering antibody-mediated enhancement or Th-2 immunopathology, and some have missed some important but less antigenic epitopes in the receptor binding domain. Therefore, this study used in-silico methods to design and evaluate a potential multiepitope vaccine that specifically targets the receptor-binding domain due to its critical function in viral entry. Immunoinformatic tools were used to specifically examine the receptor-binding domain of the surface glycoprotein for suitable T cell and B cell epitopes. The selected 5 B cell and 8 T cell epitopes were then constructed into a subunit vaccine and appropriate adjuvants along with the universal immunogenic PADRE sequence were added to boost efficacy. The structure of the vaccine construct was predicted through a de-novo approach and molecular docking simulations were performed which demonstrated high-affinity binding to TLR 5 receptor and appropriate HLA proteins. Finally, the vaccine candidate was cloned into an expression vector for use as a recombinant vaccine. Similarities to some recent epitope mapping studies suggest a high potential for eliciting neutralizing antibodies and generating a favorable overall immune response.
Dissecting mortalities and injuries: Spatio-temporal hotspots detection of traffic accidents casualties in Saudi Arabia
Authors: Alghafees Mohammad A. , Alwatban Saud , Rizk Ahmed
Published: June 2022

Background: Traffic accidents (TA) are one of the leading causes of mortality in Saudi Arabia. Despite the state efforts to combat this issue, a dearth of knowledge on TA's spatial and temporal patterns in Saudi Arabia is present.This study aims to detect significant Spatio-temporal TA casualties' hotspots to increase the understanding of moralities and injuries' trends.Methods: We used machine-learning models to detect the significant temporal anomalies in casualties. Afterwards, we performed spatial analysis (Local Moran's I, Getis-Ord Gi*) to detect Spatio-temporal hotspot in casualties.Results: TA casualties are steadily declining. However, annual spikes in the month of Ramadan are present. Spatial analysis suggests that TA casualties are associated with population count and location. Urban centers have higher casualties due to high population count. Aggregating TA casualties per capita shows that these regions have in reality the lowest rates of casualties, and rural regions in the north are more impacted by TA.

Published: June 2022

Widespread use of Mobile phones and digital technology has warranted the research on the possible side effects of the excessive use of the technology. At the same time, it is imperative to find out ways to minimize the damage caused by excessive exposure. Many studies have reported various health problems due to the excessive use of Mobile Phones and Wi-Fi devices. These problems may range from headache, dizziness, lack of sleep, heart diseases, memory loss, and concentration issues to cancer in extreme cases. In this study, we have analyzed the effect of Mobile and Wi-Fi radiations on HRV and the efficacy of Envirochip which claims to neutralize the harmful impact of Mobile Phone and Wi-Fi Radiations. The study was done on 77 participants and the data was taken under three conditions (normal reading, reading with Mobile Phone and the reading with Envirochip fixed on the Mobile Phone). The study revealed that there was a reduction in the average HRV of the participants when they were talking on the Mobile Phone and an increase in the average HRV of the participants was seen when Envirochip was fixed on the Mobile Phones and the nearby Wi-Fi devices. However, a study on larger sample size is required to validate the finding of this pilot study.

Authors: Wang Mengshan , Chung Andrew
Published: June 2022

IL-23R has been found to contribute to susceptibility to cancer such as leukemia. However, the mechanism of IL23R in Regulatory T cells (Tregs) of cancers is still unknown. Here, our objective is to identify the key molecules, biological processes, and signaling pathways by analyzing the RNA-seq data. The GSE197287 was created by the Illumina HiSeq 4000 (Mus musculus). The gene enrichment analyses showed that autophagy and yersinia infection are the main signaling pathways in the Tregs with the knockout of IL23R. In addition, we identified the top ten interactive molecules including CDK1, POLR2A, FN1, MAPK8, CUL3, BARD1, TPX2, TRAF6, DTL, and MCM5. This study may benefit the clinical work of the treatment of leukemia.

Published: June 2022

Background
We estimated the association between the level of restriction in nine different fields of activity and SARS-CoV-2 transmissibility in Spain, from 15 September 2020 to 9 May 2021.
Methods
A stringency index (0 to 1) was created for mobility, social distancing, commerce, indoor and outdoor bars and restaurants, culture and leisure, worship and ceremonies, indoor and outdoor sports, for each Spanish province (n = 50) daily. The logarithmic return (LR) of the weekly percentage variation of the 7-days COVID-19 cumulative incidence was used to measure COVID-19 transmission, lagged 12 days behind the stringency index. A hierarchical multiplicative model was fitted, and the median of coefficients across provinces (with 95% bootstrap confidence intervals) was used to quantify the effect of increasing one standard deviation (1SD) in the stringency index in each field.
Results
Highest levels of restriction were seen in mobility, sports and restaurants, particularly indoors. The increase in restrictions overall reduced SARS-CoV-2 transmission by 22% (RR = 0.78; one-sided 95%CI: 0,0.82) in one week, with highest effects for culture and leisure 14% (0.86; 0,0.98), social distancing 13% (0.87; 0,0.95), indoor restaurants 10% (0.90; 0,0.95) and indoor sports 6% (0.94; 0,0.98). In a reduced model with seven fields, culture and leisure no longer had a significant effect while ceremonies decreased transmission by 5% (0.95; 0,0.96). Models R2 was around 70%.
Conclusion
Increased restrictions decreased COVID-19 transmission. Limitations include remaining collinearity between fields, and somewhat artificial quantification of qualitative restrictions, so the exact attribution of the effect to specific areas must be done with caution.

Authors: Muller Ashley Elizabeth , Berg Rigmor C , Meneses-Echavez Jose Francisco , Ames Heather M. R. , Borge Tiril C. , Jardim Patricia Sofia Jacobsen , Cooper Chris , Rose Christopher James
Published: June 2022

Background: Machine learning (ML) tools exist that can reduce or replace human activities in repetitive or complex tasks. Yet ML is underutilized within evidence synthesis, despite the steadily growing rate of primary study publication and need to periodically update reviews to reflect new evidence. Underutilization may be partially explained by a paucity of evidence on how ML tools can reduce resource use and time-to-completion of reviews.Study design and setting: This protocol describes how we will answer two research questions using a retrospective study design: Is there a difference in resources used to produce reviews using recommended ML versus not using ML, and is there a difference in time-to-completion? We will also compare recommended ML use to non-recommended ML use that merely adds ML use to existing procedures. We will retrospectively include all reviews conducted at our institute from 1 August 2020, corresponding to the commission of the first review in our institute that used ML. We will use the results from this study to design a rigorous, multi-institutional, prospective study that will additionally explore review quality.Conclusion: We invite other evidence synthesis groups to adopt and adapt this protocol and to collaborate with us.

Published: June 2022

Over 50% of Healthcare-Associated Infections happen due to the hand of healthcare providers. The majority of health care workers end up not washing their hands because of different reasons. Therefore, this study aimed to assess the proportion of handwashing coverage and the associated factors among health care workers in public and private health care facilities in Ndejje division, Makindye Ssabagabo municipality, Wakiso district. A descriptive cross-sectional study design was conducted employing both quantitative and qualitative methods of data collection. A total of 350 health care workers were interviewed using a self-administered structured open-ended paper questionnaire. Focus Group Discussions (FGD) guide and an observation paper checklist were also employed for data collection process. The quantitative data was entered in Epidata and exported to SPSS for descriptive univariate analysis. The qualitative data was analyzed manually by thematic analysis to generate codes, subthemes, and key themes. Our results showed that female health care workers constituted the majority of the respondents 205 (58.6%). The majority 324 (92.6%) of health care workers were from private health facilities. We found out that the proportion of handwashing facilities coverage was 97.7%. Removal of germs 317 (95.5%) was reported as the major reason for washing hands. Health care workers reported that handwashing with soap and water was at times being substituted with the use of a hand sanitizer due to its convenience. The proportion of handwashing was good coupled with positive attitude towards handwashing. Being a nurse was highly associated with washing hands in both private and public health facilities. High hand washing proportion was attributed to the COVID-19 guidelines which sparked adherence to the standard operating procedures. Different stakeholders should sustain this current handwashing which will curb Water, Sanitation and Hygiene related diseases.
The role of plasmonic metal-oxides core-shell nanoparticles on the optical absorption of Perovskite solar cells
Authors: Ullah Ihsan , Saghaei Hamed , Khan Jahangeer , Shah Said Karim
Published: June 2022

Among all the different methods to enhance the optical absorption of photovoltaic devices. The plasmonic effect is one the most prominent and effective ways to capture more incident light and also provide good carrier dynamic management. Here, we systematically introduce spherical gold nanoparticles (Au NPs) with different radii in the absorber layer of perovskite solar cells (PSCs). The overall enhanced optical absorption of around 14.20% and 20.02% is achieved for incorporated monolayer and bilayer Au NPs, respectively, in the active layer compared to the pure perovskite layer. Moreover, we employ the metal (Au)-dielectric (TiO2 and SiO2) nanoparticles in the absorber layer. The optical absorption increases as the core-shell size decreases. The optical absorption elevates in both Au@TiO2 core-shell and Au@SiO2 core-shell 17.5% and 3.5%, respectively. These results support superior separation and transfer of charge in the existence of plasmonic NPs. In addition, this study presents a very sophisticated approach in the optical enhancement of PSCs and thus helps to boost the overall photovoltaic device performance.

Published: June 2022

Unlike traditionally-mapped Raman imaging, stimulated Raman scattering (SRS) imaging achieved the capability of imaging metabolic dynamics and a greatly improved signal-noise-ratio. However, its spatial resolution is still limited by the numerical aperture or scattering cross-section. To achieve super-resolved SRS imaging, we developed a new deconvolution algorithm – Adam optimization-based Pointillism Deconvolution (A-PoD) – for SRS imaging, and demonstrated a spatial resolution of 52 nm on polystyrene beads. By applying A-PoD to spatially correlated multi-photon fluorescence (MPF) imaging and deuterium oxide (D2O)-probed SRS (DO-SRS) imaging data from diverse samples, we compared nanoscopic distributions of proteins and lipids in cells and subcellular organelles. We successfully differentiated newly synthesized lipids in lipid droplets using A-PoD coupled with DO-SRS. The A-PoD-enhanced DO-SRS imaging method was also applied to reveal the metabolic change in brain samples from Drosophila on different diets. This new approach allows us to quantitatively measure the nanoscopic co-localization of biomolecules and metabolic dynamics in organelles. We expect that the A-PoD algorithm will have a wide range of applications, from nano-scale measurements of biomolecules to processing astronomical images.
Präsenzgefühl und Selbstwirksamkeitserwartung im VR-Klassenzimmer
Authors: Wiepke Axel
Published: June 2022

Moderne Trainingsansätze ermöglichen den Einsatz immersiver Technologien in Ausbildung und Studium, mitunter für das Gefühl, sich in der mediierten Welt zu befinden (Präsenz). Präsenz erfahren Konsumierende von Medien, wenn sie sich in der mediierten Welt verorten und sie als primären Handlungsraum einstufen. Indem die Welt als Interaktionsraum wahrgenommen wird, wird die Grundlage geschaffen, um Herausforderungen selbst zu lösen. Trainings sollen Lernende weiterhin bei der subjektiven Gewissheit, zukünftige Herausforderungen aufgrund ihrer eigenen Kompetenzen bewältigen zu können (Selbstwirksamkeitserwartung), unterstützen. So wird die These aufgestellt, dass Präsenz einen positiven Einfluss auf Selbstwirksamkeit hat. Dies wird mit einer Virtual-Reality-Trainingsumgebung im Lehramtsstudium im Fach Geschichtsdidaktik untersucht und schlussendlich falsifiziert.

Published: June 2022

This paper summarizes the arguments and counterarguments within the scientific discussion on the issue of governance and taxation revenue performance. The main purpose of the research is to examine the influence of management on tax revenue performance in West African countries. Specifically, the study aimed to investigate the impact of regulatory quality (political stability) and (voice and accountability) on tax revenue performance in West African countries; and to assess the effect of governance efficiency (the rule of law and control of corruption) on the performance of tax generation of West African countries. Secondary data were sourced from Governance indicators which cover 2005 to 2017. Regression analysis was employed to test the research hypotheses: regulatory quality does not significantly influence tax revenue performance in West African countries; and government efficiency does significantly affect tax revenue in West African countries. Sixteen West African countries were purposively chosen because of governance issues such as political instability and government ineffectiveness. The paper presents the results of an empirical analysis, which showed that regulatory quality, political stability and absence of violence, and voice and accountability have insignificant impacts (p-value>5% level of significance) on tax revenue performance. Moreover, government effectiveness, the rule of law and control of corruption have positive and significant impacts (p-value<5% level of significance) on tax revenue performance in West African countries. The study concludes that governance affects tax revenue performance in West African Countries; thus, the study recommends, among others that government should come up with realistic policies that will increase public and civil service quality.

Published: June 2022

As a social phenomenon and a mechanism for influencing others, leadership always has interested scientists. Literary reviews on the theoretical foundations, types of classifications, and prospects for leadership development are an essential element of careful study of this concept. Today, the systematization of types of leadership on various grounds is a necessary component for understanding the nature of this phenomenon. The paper analyzes 2,000 published research papers from the Scopus database, identifying critical terms related to leadership. Establishing links between leadership and related concepts creates the most accurate picture for further research on this topic. The study is devoted to studying the theoretical and practical experience of scientists worldwide who research management as a critical aspect in building an effective organization. Systematization of such data is the basis for identifying current and fundamentally new directions of effective leadership. The keyword in the described bibliometric analysis was the concept of “leadership”. New clusters have been formed with the most influential definitions of transformational leadership, communication, and shared leadership. The combination of quantitative and qualitative research methods determined the future directions of study in the further search for effective leadership tools. The content analysis of the most cited scientific works was carried out in the research, which reveals the essence of tools for the development of effective leadership and the need for timely diagnosis of the negative behavior of managers. Bibliometric analysis and analysis of the development of leadership theory reveal the need to implement the principles of Network Leadership Theory in modern organizations, which are the basis of the state’s economic development as a whole.
The Impact of Setting up a Cloud Computing Solution on Small and Medium Organization’s Management: A Qualitative Study
Authors: Djamila Toumi Amara , Abdelatif Maza
Published: June 2022

As we know, organizations are systems that affect their surrounding environment and get involved with their environment. Any changes can impact the outcome of any operation and decision in the organization, no matter how small it is or how irrelevant, from the most straightforward operation or process to the most complicated functions and strategic decisions. Migrating to cloud computing is one of the most important enterprise goals. This technology impacts the use of information and communication profoundly. Its main goal is to provide data storage and net computing services that are secure, rapid, and convenient. In this sense, the small and medium enterprise is the most interested since initial investments are avoided, and the technology allows gradual implementation. The present study aims to introduce the advantages of implementing cloud computing in small and medium enterprises. This paper studies cloud computing and its impact on the organization, which was carried out using a qualitative methodology to show the elements that may get impacted the most and the consequences of its adoption. By interviewing 13 managers and experts from four small and medium companies. Qualitative content analysis and open coding were used to analyze the data. Subsequently, five sub-themes were extracted from the central theme of the impact of cloud implementation on operational management in organizations. The sub-themes included information access, communication, collaborative work, and customer and supplier relationships. We found out that migrating into the cloud for organizations is primarily beneficial, with some exceptions, of course, any system or any technology has flaws, but in the case of the cloud technology, the benefits are more cover the flaws, especially if the implementation was well planned and well maintained, and we provide all the conditions needed for the good functioning of this technology.
The Relationship Between the Scientific Activities in Research Laboratories with Webometrics Ranking of Algerian Universities: An Empirical Investigation
Authors: Nezai Azzeddine , Ramli Mohamed , Refafa Brahim
Published: June 2022

Algeria has paid attention to the higher education and scientific research sector through the five-year scientific research and technological development programs (1998-2002, 2008-2012, and 2014-2019). The study aims to evaluate the scientific research activities in Algerian universities within the framework of scientific research programs, to study the relationship of scientific activities by researchers in Algerian research laboratories with Webometrics ranking of Algerian universities. It is eluted what are the scientific activities of Algerian researchers which have the most impact on the ranking of Algerian universities in the Webometrics ranking. We adopted the experimental, exploratory approach by collecting, exploring, and analyzing the correlation between of data from the Algerian university rankings according to the number of researchers in the research laboratories, the number of citations, the number of patents, published papers, and the ranking of each Algerian university in Webometrics ranking, by Spearman’s correlation coefficient to test the strength and signification of the correlation between these rankings. The results showed development in the various components of scientific, material, human and financial research, but it is not enough. Also, despite many research laboratories, researchers at these laboratories, and the improvement in the number of internationally published research in each Algerian university, this did not contribute to improving its global Webometrics ranking due to the weakness of the relationship with activities of researchers in Algerian research laboratories. The result showed that the Algerian university is not interested in its virtual presence on the web, which negatively affected its Webometrics ranking. The researchers conclude that to improve the ranks of Algerian universities in various aspects, they must improve their global ranking according to the number of citations. Accordingly, to improve the ranking, international visibility of Algerian universities, decision-makers must adopt indicators of ‘research quality’ (number of citations), ‘research production’ (publications) in financing and accrediting research laboratories.
A Contingent Resource-Based Perspective on Corporate Social Responsibility and Competitive Advantage: A Focus on Transition Countries
Authors: Djalilov Khurshid
Published: June 2022

Although many studies investigate the relationship between corporate social responsibility (CSR) and performance, they mainly explore the U.S. and Western developed countries and ignore other emerging economies and transition countries. However, the Contingent Resource-Based View (Contingent RBV) argues that the CSR-performance link varies across different business environments. Due to the absence of relevant research, little is known about the underlying mechanisms associated with the CSR-performance nexus in transition countries. Thus, the aim of this research is to investigate the moderating role of the business environment, namely dynamism, on the CSR-performance relationship in the banking sector of 21 transition countries for the period 2002 to 2014. We specifically chose the period of 2002-2014 as this best captured a mix of turbulent and stable transition countries. This study applied system GMM while exploring an unbalanced panel sample for 319 commercial banks and considering the dynamic nature of bank performance. Moreover, this approach allowed us to control the endogeneity problems successfully. The findings indicated that the direct association between CSR and performance was negative, but the opposite was confirmed when the link was moderated by Dynamism. Specifically, system GMM showed that Total CSR, Community involvement and Environment had a positive association with banks’ competitive advantage in a dynamic context. This study concluded by highlighting the theoretical and managerial implications.
Global form of flavor symmetry groups in 4d N=2 theories of class S
Authors: Bhardwaj Lakshya
Published: June 2022

We provide a systematic method to deduce the global form of flavor symmetry groups in 4d N=2 theories obtained by compactifying 6d N=(2,0) superconformal field theories (SCFTs) on a Riemann surface carrying regular punctures and possibly outer-automorphism twist lines. Apriori, this method only determines the group associated to the manifest part of the flavor symmetry algebra, but often this information is enough to determine the group associated to the full enhanced flavor symmetry algebra. Such cases include some interesting and well-studied 4d N=2 SCFTs like the Minahan-Nemeschansky theories. The symmetry groups obtained via this method match with the symmetry groups obtained using a Lagrangian description if such a description arises in some duality frame. Moreover, we check that the proposed symmetry groups are consistent with the superconformal indices available in the literature. As another application, our method finds distinct global forms of flavor symmetry group for pairs of interacting 4d N=2 SCFTs (recently pointed out in the literature) whose Coulomb branch dimensions, flavor algebras and levels coincide (along with other invariants), but nonetheless are distinct SCFTs.
Long-term memory magnetic correlations in the Hubbard model: A dynamical mean-field theory analysis
Authors: Watzenböck Clemens , Fellinger Martina , Held Karsten , Toschi Alessandro
Published: June 2022

We investigate the onset of a not-decaying asymptotic behavior of temporal magnetic correlations in the Hubbard model in infinite dimensions. This long-term memory feature of dynamical spin correlations can be precisely quantified by computing the difference between the zero-frequency limit of the Kubo susceptibility and the corresponding static isothermal one.
Here, we present a procedure for reliably evaluating this difference starting from imaginary time-axis data, and apply it to the testbed case of the Mott-Hubbard metal-insulator transition (MIT). At low temperatures, we find long-term memory effects in the entire Mott regime, abruptly ending at the first order MIT. This directly reflects the underlying local moment physics and the associated degeneracy in the many-electron spectrum. At higher temperatures, a more gradual onset of an infinitely-long time-decay of magnetic correlations occurs in the crossover regime, not too far from the Widom line emerging from the critical point of the MIT.
Our work has relevant algorithmic implications for the analytical continuation of dynamical susceptibilities in strongly correlated regimes and offers a new perspective for unveiling fundamental properties of the many-particle spectrum of the problem under scrutiny.
The Lenaian Festival at Classical Athens in Sociocultural Context
Authors:   Institute of World History of the Russian Academy of Sciences, Karpyuk Sergey G. , Kulishova Oksana V. ,   St. Petersburg State University
Published: June 2022

This article covers the Lenaia (Λήναια) which was an important part of social and political life in Classical Athens. Our understanding of how dramatic agones in Athens were organized primarily comes from the accounts of the Great (City) Dionysia, while other festivals have been studied less thoroughly. The unique nature of the Lenaia manifested itself both in the purely theatrical and in the social aspects of the event. Regarding the leading theatrical genre, tragedy, the Lenaia remained in the shadow of the City Dionysia, playing the role of the “small stage”. The comic agones at the Lenaia, on the other hand, were staged to a very high standard, to which the social aspect further contributed since the audiences at the Lenaia were much more down-to-earth, animated and active that at the Dionysia. The Lenaia was held during the coldest part of the year. It was precisely in winter when peasants from different parts of Attica, who constituted the majority of the Lenaian audience, were less busy with farming; unlike the Great Dionysia, the Lenaia was not attended by foreigners. The Lenaian festivals were held on a less lavish scale, their organization was entrusted to less significant magistrates, and their performances were much less costly than the Dionysian ones. The Athenians must have considered the Lenaia a predominantly peasant festival, inaccessible to outsiders. Lenaian performances were but little affected by “political correctness”, their earthy humour at times evolved into biting political satire. All of the above created a special atmosphere that became the background of Aristophanes’ best comedies.
Cossack Adventure of Walerian Kalinka, a Prospective Monk of the Ressurectionist Congregation
Authors:   Katolicki Uniwersytet Lubelski, Osadczy Włodzimierz
Published: June 2022

Before starting a career as a Polish priest and scholar, Walerian Kalinka took part in various initiatives aimed at restoring Poland’s independence. One of the most “exotic” of his enterprises was his participation in the formation of the so-called Sultan Cossacks detachments, military units consisting of the Slavic population. From the perspective of Polish emigrants, the time of the confrontation between Russia and Turkey (and Western powers) was ideal for the formation of the Polish army. Kalinka was as an adjutant to General Władysław Zamoyski and on his behalf led the recruitment into the army, and also transformed the already existing detachment of the violent Michał Czajkowski, known as Sadyk-Pasha, into a unit of the Polish character regarding discipline and ties with emigration circles. Despite the weakening of Russia’s position, the new balance of political forces after the Crimean War did not contribute to the revival of Poland as a sovereign state. Many Polish soldiers abroad went through an internal crisis. Kalinka managed the demobilization of Cossack volunteers and sought a place for them in emigration. Once again, the war did not lead to freedom. Remaining under the influence of religiosity of general Zamoyski, Kalinka began to pay more attention to the connection between the national question and Catholicism. Thus, Kalinka became close to the already existing Order of the Resurrection of the Our Lord, also called Resurrectionists. Afterwards, he joined this order and became a humble monk, who, however, never gave up geopolitical illusions and, through religious initiatives, tried to realize his political dreams.
The Contexts behind the Creation of Anton Kartashev’s Book about Holy Rus’
Authors:   Petrozavodsk State University, Antoshchenko Aleksandr V.
Published: June 2022

Based on archival and published sources, the author analyzes complex contexts of writing a narrative about Holy Rus’ by a well-known émigré historian. The political and ideological contexts were determined by changes in the composition and sentiments of Russian refugees after the Second World War. On the one hand, the spread of “Soviet patriotism” among some emigrants of the first wave as a result of their acknowledgement of the decisive victory of the Red Army encouraged the historian to remind them about the anti-Bolshevik origins of the post-revolutionary emigration. On the other hand, his book represented a religiously grounded ideal which could serve as the basis for cultural and historical identity of the anti-Soviet “displaced persons”. The religious context was primarily determined by the failure to unite the Orthodox jurisdictions of Russian emigrants after the World War II, which required the historian to dissociate himself from the reactionary program of protagonists of the Russian Orthodox Church Abroad. The situation was further complicated by the disagreement between older and younger generations of the representatives of the “School of Parisian theology”, which characterized the academic context. As a result, Kartashev had to disassociate himself with those of his disciples who did not follow his interpretation of the Chalcedonian dogma. Last but not least, the organizational and financial contexts, which also depended on the ideological and political contexts, meant that he could not seek financial support from the American curator of Saint Sergius theological institute in Paris, but applied for it to Novitsky brothers who organized fundraising activity among Russian Orthodox emigrants in the United States to ensure publication of the book.
The Formation of American Post-war Belarusian Studies

Published: June 2022

American post-war Belarusian studies during its initial stage differed from similar processes in other countries. The CIA, which was interested in using the Belarusian emigration for its own purposes, the Congress, and some senators, with whom the leadership of the Belarusian- American Association actively worked, originally played a significant role. The CIA supported the activities of the Chairman of the Rada of the Belarusian People’s Republic (in exile) Nikolai Abramchik, who was one of the first Belarusian emigrants to publicly declare Moscow’s anti-Belarusian policy, using such concepts as the “Russian genocide of the Belarusian people”, “occupation of Belarusian lands”, etc., calling on America to “protect the oppressed Belarusian people”. In 1954, a special commission of the Congress held hearings on the topic “The Communist seizure and occupation of Belarus”, during which a kind of methodological guidelines for the “correct” study of the history of Belarus were determined. Against the background of McCarthyism and the fight against the “Red scare” allegedly coming from Moscow, it completely fitted into the so-called totalitarian concept in American Russian studies (then Sovietology), and hence Belarusian studies, which was being formed. It was in such a difficult political and ideological situation that the first study by N. P. Vakar “Belarus. The Creation of a Nation” was being created in the Russian Research Center of Harvard, which was published in 1956, and not only received general recognition in the American scholarly community, but also superseded all kinds of political pamphlets in the academic space.
Removal of sediment through hydro-suction revisited: An extensive review of the hydro-suctioning method, widely used for sediment removal from the water bodies
Authors: Jaiswal Akash , Ahmad Z. , Mishra S. K.
Published: June 2022

Hydro-suctioning is used to remove the deposited sediment from water bodies. A suction pipe is placed on/above/below the sediment bed, and deposited sediment is removed using suction. The sediment movement during hydro-suction, flow pattern, temporal sediment concentration, and scour profile are reviewed extensively and summarized in this paper. It is seen that the sediment removal initiates due to lift forces and continues further due to a change in flow field that creates sediment resuspension. The sediment removal ceases if the suction inlet reaches a distance, i.e., critical suction inlet depth. Within this critical zone, when the hydro-suction initiates, sediment just below the suction pipe is first removed, leading to the maximum scour depth, i.e., below the sediment bed level. In this process, sediment from sides of the scour hole is hydrodynamically dragged towards the center, where it gets deposited, and a hump is formed at the center. At equilibrium, the sediment removal ceases. This paper discusses the equations predicting scour profile and critical inlet depth. It is seen that the research work dealing with the standardization of hydro-suction for fixation of suction pipe diameter, suction inlet depth, discharge, etc. is in quite a primitive stage and needs urgent attention.
Reciprocating subsurface-flow constructed wetlands: a microcosm treatability study
Authors: Behrends Leslie , Houke Laura , Bailey Earl , Jansen Pat
Published: June 2022

Two batch-loaded microcosm treatability studies of eight days' duration (192 hours) were conducted concurrently from July 26 through August 3 in an environmentally controlled greenhouse at the Tennessee Valley Authority's (TVA) Constructed Wetlands Research Facility in Muscle Shoals, Alabama, USA. These, the first of five treatability studies, were conducted in batch-loaded wetland microcosms, with and without reciprocation. Reciprocation refers to the process of filling and draining paired wetland cells on a recurrent and timed basis to facilitate passive aeration of fixed microbial biofilms during the drain phase and oxygen depletion during the fill phase. The study was designed to simultaneously evaluate the influence of three treatment parameters with respect to removal dynamics of chemical oxygen demand (COD), total ammonia-nitrogen (TAN), nitrate-nitrogen, and orthophosphorus. The treatment parameters evaluated included four COD concentrations, two reciprocation cycle times, and the presence or absence of reed canary grass (Phalaris arundinacea), a plant with an anoxic rootzone. Temperature, pH, dissolved oxygen, electrical conductivity, redox potential, and evapotranspiration were also monitored. Results showed that treatments with reciprocation vs. no reciprocation provided significantly enhanced aerobic and anoxic treatment of wastewater and improved removal of COD and ammonium, irrespective of initial COD concentrations or planted vs. not planted with P. arundinacea. Treatments with P. arundinacea had less accumulation of nitrate nitrogen; less than 0.4 mg/L., while reciprocating treatments without P. arundinacea accumulated from 15–26 mg/L nitrate nitrogen over the 192-hour treatment period.

Published: June 2022

The abnormal development of one or more teeth exceeding the number considered normal is defined as hyperdontia, or supernumerary teeth. Supernumerary teeth are usually diagnosed by routine radiographs, because in most cases they are asymptomatic and do not erupt. The prevalence of supernumerary teeth is low, ranging between 0.1 and 3.8%. Objective: To report a case of multiple non-erupted fourth molars. Case report: Patient M.N.S, 16 years old, female, leucoderma, in good health status attended the dental clinic referred by the orthodontist. On panoramic radiography, the germs of the teeth #18, #28, #38 and #48 were detected and retained. Also, the presence of three forth molars distally to the teeth #18, #28 and #38 were observed. The surgical removal of all third and fourth molars was performed under local anesthesia, in two steps: left and right sides. The patient has been followed for 1 year. Fourth molar prevalence is higher in males (2:1), differing from the patient of this case report. A few cases of multiple supernumerary teeth in non-syndromic patients are reported in the literature. Conclusion:Both early diagnosis and treatment are important to prevent crowding, failure of eruption, displacement of teeth, impairment of orthodontic treatment, gingivitis, and formation of abscess, cysts, and odontogenic tumors.
