Information visualization analysis based on historical data
Authors: Zhang Yukun , Wu Bei , Tan Lifeng , Liu Jiayi
Published: May 2021

Visual expression is increasingly used in historical research due to its intuitiveness and distinctness. However, most of the common research contents focus on the spatial concept, but lack the visualization analysis of the attribute characteristics of the research elements. In order to achieve this goal, based on a case study of the coastal military defense system in Ming Dynasty, the Geographic Information System (GIS) platform was adopted to reconstruct the historical map and its spatial data were extracted. On this foundation, the attribute characteristics of the military settlements, accessibility, was quantified by constructing a hierarchy evaluation model, and then the results were projected into the spatial geographic coordinates to realize the visualization of the accessibility of the military settlements in Ming Dynasty. The results showed that the combined method of quantification and visualization not only enabled more comprehensive and intuitive display of historical information, but also promoted data extraction and correlation analysis, creating a possibly for more in-depth future research.
Recent Developments of Transition Metal Compounds-Carbon Hybrid Electrodes for High Energy/Power Supercapacitors
Authors: Ren Kang , Liu Zheng , Wei Tong , Fan Zhuangjun
Published: May 2021

Due to their rapid power delivery, fast charging, and long cycle life, supercapacitors have become an important energy storage technology recently. However, to meet the continuously increasing demands in the fields of portable electronics, transportation, and future robotic technologies, supercapacitors with higher energy densities without sacrificing high power densities and cycle stabilities are still challenged. Transition metal compounds (TMCs) possessing high theoretical capacitance are always used as electrode materials to improve the energy densities of supercapacitors. However, the power densities and cycle lives of such TMCs-based electrodes are still inferior due to their low intrinsic conductivity and large volume expansion during the charge/discharge process, which greatly impede their large-scale applications. Most recently, the ideal integrating of TMCs and conductive carbon skeletons is considered as an effective solution to solve the above challenges. Herein, we summarize the recent developments of TMCs/carbon hybrid electrodes which exhibit both high energy/power densities from the aspects of structural design strategies, including conductive carbon skeleton, interface engineering, and electronic structure. Furthermore, the remaining challenges and future perspectives are also highlighted so as to provide strategies for the high energy/power TMCs/carbon-based supercapacitors.
Ultrafast proton release reaction and primary photochemistry of phycocyanobilin in solution observed with fs-time-resolved mid-IR and UV/Vis spectroscopy

Published: May 2021

Deactivation processes of photoexcited (λex = 580 nm) phycocyanobilin (PCB) in methanol were investigated by means of UV/Vis and mid-IR femtosecond (fs) transient absorption (TA) as well as static fluorescence spectroscopy, supported by density-functional-theory calculations of three relevant ground state conformers, PCBA, PCBBand PCBC, their relative electronic state energies and normal mode vibrational analysis. UV/Vis fs-TA reveals time constants of 2.0, 18 and 67 ps, describing decay of PCBB*, of PCBA* and thermal re-equilibration of PCBA, PCBBand PCBC, respectively, in line with the model by Dietzek et al. (Chem Phys Lett 515:163, 2011) and predecessors. Significant substantiation and extension of this model is achieved first via mid-IR fs-TA, i.e. identification of molecular structures and their dynamics, with time constants of 2.6, 21 and 40 ps, respectively. Second, transient IR continuum absorption (CA) is observed in the region above 1755 cm−1(CA1) and between 1550 and 1450 cm−1(CA2), indicative for the IR absorption of highly polarizable protons in hydrogen bonding networks (X–H…Y). This allows to characterize chromophore protonation/deprotonation processes, associated with the electronic and structural dynamics, on a molecular level. The PCB photocycle is suggested to be closed via a long living (> 1 ns), PCBC-like (i.e. deprotonated), fluorescent species.
Construing Cultural Heritage: The Stagings of an Artist
Authors: Malm Mats
Published: May 2021

This study examines how an artist construed himself as cultural heritage by the turn of the 19th century, how this heritage was further construed after his death, and how the artworks can be made to further new approaches and insights through a digital archive (aroseniusarchive.se). The study employs the concept of 'staging' to capture the means used by the artist, as well as by reception, in this construal. The question of 'staging' involves not only how the artist has been called forth from the archives, but also how the artist can be called forth in new ways today through digitization. The study first elaborates on the theoretical framework through the aspects of mediation and agency, then explores how the artist was staged after his death. Finally, the artist's own means of staging himself are explored. Swedish painter Ivar Arosenius (1878–1909) is the case studied.
Drug Policy in India: An Analysis
Authors: Thakur Bharti , Mittal Neeru
Published: May 2021

The Narcotic Drugs and Psychotropic Substances Act, or NDPS Act, was enacted to control addictive drugs and prohibit their possession, dispersion, sale, import, and trade in India. Psychotropic agents have the potential to change an individual’s consciousness, while narcotic drugs relieve anxiety. The Indian Parliament passed the NDPS Act on November 14, 1985. Nonetheless, these types of drugs are important in the practice of medicine. Consequently, the Act contains provisions for the cultivation of cannabis, poppy, and coca seeds and the production of certain psychotropic medicines used for medical purposes. The Act’s primary objective is to regulate the manufacturing, ownership, selling, and transportation of narcotics and psychotropic drugs. The Act forbids the selling of nearly 200 psychotropic medications, resulting in these drugs being inaccessible over the counter to the general public. These medications are only available for use with a prescription. Violations of this law can result in a sentence of incarceration or a fine, or both, depending on the offense’s severity, which is determined by the severity of the situation at hand. If the drugs are being used for personal benefit, the penalty can be minimized. Furthermore, the legislation has been revised several times since its inception.

Published: May 2021

Commercializing biomedical discoveries is a challenging process for many reasons. However, Academic Medical Centers (AMC) that have teaching, patient care, research, and service engrained in their mission are well poised to host these discoveries. These academic discoveries can lead to improvement in patient health and economic development if supported to cross the “valley of death” through institutional assistance, by providing guidance, gap funding and product development expertise. Colorado has a vibrant local startup ecosystem, state support for commercialization and entrepreneurship as well as critical mass of product development expertise. University of Colorado Anschutz Medical Campus, as a major AMC, is an engine for growth for the region. This article discusses innovation efforts at the University of Colorado Anschutz Medical Campus as a case study, which is built around two major efforts: the CCTSI and CU Innovations. I-Corps at CCTSI and the SPARK|REACH program of CU Innovations have been instrumental in fostering innovation, commercialization, and entrepreneurship on the campus.
The Holy Spirit “Artisan of the Eucharist”? A Critical Analysis and Evaluation of the Epicleses in the Eucharistic Prayers of the Roman Rite
Authors: Moons Jos
Published: May 2021

The current article analyzes and evaluates how the explicit Spirit-epicleses in the new eucharistic prayers of the Roman rite image the Holy Spirit. The author demonstrates that the Holy Spirit is usually described in dependence from the Father or the Son (e.g., “his Spirit”) or as the instrument that the Father sanctifies with or through (e.g., “through the Spirit”), and less frequently as actively sanctifying. As we tend to talk about the Holy Spirit's epicletic involvement in a more active way than the epicleses actually do, the author pleads for more accurate language. Further, he wonders what the results of the analysis mean in the light of the Trinity's dynamic complementarity and Geistvergessenheit. Finally, he argues that talking about the Spirit as “artisan” does not inevitably lead to tritheism, as a healthy Trinitarian theology equally promotes both God's unity and three-ness.

Authors: Wang Wen , He Qiao , Zhu Shichao , Wang Mingqi , Kang Yan , Zhang Rui , Ji Peng , Zou Kang , Zong Zhiyong , Sun Xin
Published: May 2021

Objectives:

The association between blood transfusion and ventilator-associated events (VAEs) has not been fully understood. We sought to determine whether blood transfusion increases the risk of a VAE.

Design:

Nested case-control study.

Setting:

This study was based on a registry of healthcare-associated infections in intensive care units at West China Hospital system.

Patients:

1,657 VAE cases and 3,293 matched controls were identified.

Methods:

For each case, 2 controls were randomly selected using incidence density sampling. We defined blood transfusion as a time-dependent variable, and we used weighted Cox models to calculate hazard ratios (HRs) for all 3 tiers of VAEs.

Results:

Blood transfusion was associated with increased risk of ventilator-associated complication-plus (VAC-plus; HR, 1.47; 95% CI, 1.22–1.77; P <.001), VAC-only (HR, 1.29; 95% CI, 1.01–1.65; P = .038), infection-related VAC-plus (IVAC-plus; HR, 1.78; 95% CI, 1.33–2.39; P < .001), and possible ventilator-associated pneumonia (PVAP; HR, 2.10; 95% CI, 1.10–3.99; P = .024). Red blood cell (RBC) transfusion was also associated with increased risk of VAC-plus (HR, 1.34; 95% CI, 1.08–1.65; P = .007), IVAC-plus (HR, 1.70; 95% CI, 1.22–2.36; P = .002), and PVAP (HR, 2.49; 95% CI, 1.17–5.28; P = .018). Compared to patients without transfusion, the risk of VAE was significantly higher in patients with RBC transfusions of >3 units (HR, 1.73; 95% CI, 1.25–2.40; P = .001) but not in those with RBC transfusions of 0–3 units.

Conclusion:

Blood transfusions were associated with increased risk of all tiers of VAE. The risk was significantly higher among patients who were transfused with >3 units of RBCs.

Published: May 2021

Objective:

To evaluate the impact of a vancomycin-resistant Enterococcus (VRE) screening policy change on the incidence of healthcare-associated (HA)-VRE bacteremia in an endemic hospital setting.

Design:

A quasi-experimental before-and-after study.

Setting:

A 1,989-bed tertiary-care referral center in Seoul, Republic of Korea.

Methods:

Since May 2010, our hospital has diminished VRE screening for admitted patients transferred from other healthcare facilities. We assessed the impact of this policy change on the incidence of HA-VRE bacteremia using segmented autoregression analysis of interrupted time series from January 2006 to December 2014 at the hospital and unit levels. In addition, we compared the molecular characteristics of VRE blood isolates collected before and after the screening policy change using multilocus sequence typing and pulsed-field gel electrophoresis.

Results:

After the VRE screening policy change, the incidence of hospital-wide HA-VRE bacteremia increased, although no significant changes of level or slope were observed. In addition, a significant slope change in the incidence of HA-VRE bacteremia (change in slope, 0.007; 95% CI, 0.001–0.013; P = .02) was observed in the hemato-oncology department. Molecular analysis revealed that various VRE sequence types appeared after the policy change and that clonally related strains became more predominant (increasing from 26.1% to 59.3%).

Conclusions:

The incidence of HA-VRE bacteremia increased significantly after VRE screening policy change, and this increase was mainly driven by high-risk patient populations. When planning VRE control programs in hospitals, different approaches that consider risk for severe VRE infection in patients may be required.
Invasion byAmmophila arenariaalters soil chemistry, leaving lasting legacy effects on restored coastal dunes in California
Authors: Parsons Lorraine S. , Becker Benjamin H.
Published: May 2021

Many restoration projects rely on invasive plant removal to restore ecosystems. However, success of restoration efforts relying on invasive removal can be jeopardized, because in addition to displacing native plants, invasives can also dramatically impact soils. Many studies have documented invasives’ effects on soil chemistry and microbiota. While European beachgrass [Ammophila arenaria(L.) Link] is a worldwide invasive problem in coastal dunes outside northern Europe, little attention has been paid to effects of this species on soil chemistry following invasion, even though it establishes persistent, dense monocultures. In our study, we evaluated effects ofA. arenariainvasion on soil chemistry of coastal dunes at Point Reyes National Seashore (PRNS); persistence of effects following removal by mechanical or herbicide treatment (legacy effects); and effects of treatment independent of invasion. Dune restoration efforts at PRNS have met with mixed success, especially in herbicide-treated backdunes, where decomposition of deadA. arenariahas been greatly delayed. Based on results, invasion impacted 74% of 19 variables assessed, although there was a significant interaction in many cases with successional status (earlier vs. later). Almost 60% of invasion effects persisted after restoration, with legacy effects prevalent in herbicide-treated backdunes where sand deposition from adjacent beaches could not mitigate effects as it could in herbicide-treated foredunes. Mechanical removal—or inversion of invaded surface soils with less-contaminated subsoils—resulted in fewer legacy effects, but more treatment effects, primarily in backdunes. Soil chemistry may decelerate decomposition ofA. arenariadue to the limited nitrogen (N) available to enable microbial breakdown of the high carbon(C):N (70.8:1) material, but microbial factors probably play a more important role. Success of restoration at PRNS may not be fully realized until legacy effects are resolved through additional actions such as inoculation with healthy microbiomes or necromass reduction through controlled burning.
Therapeutic Crisis Intervention in Schools (TCI-S): An international exploration of a therapeutic framework to reduce critical incidents and improve teacher and student emotional competence in schools
Authors: Rodgers Stella , Hassan Sharinaz
Published: May 2021

Critical incident frameworks applied within schools are a means to support school staff to respond and guide planning to reduce critical incidents rates. This article explores the significance of the Therapeutic Crisis Intervention in Schools (TCI-S) critical incident framework to decrease the prevalence of behavioural critical incidents and to improve staff and student emotional competence in schools. The application of the TCI-S framework to reduce critical incidents within the United States and the United Kingdom school systems are demonstrated through upskilling school staff in social-emotional and co-regulation skills. It is suggested that TCI-S has the potential to support students with behavioural and emotional challenges and increase staff competency to implement trauma-informed practices that ultimately will reduce critical incidents.
‘Not Enough Time’: Identifying Victorian Teachers’ Perceptions of the Facilitators and Barriers to Supporting Improved Student Behaviour
Authors: Fox Russell A. , Sharma Umesh , Leif Erin S. , Stocker Karina L. , Moore Dennis W.
Published: May 2021

Students exhibiting behaviours of concern are at increased risk of poor outcomes during their school years. The implementation of school-wide positive behavioural interventions and supports (SWPBIS) has repeatedly been shown to be an effective, evidence-based approach that supports teachers to select and adopt effective practices to meet the social and behavioural needs of all learners. Implementation of SWPBIS within Australian schools is increasing. Although there is considerable evidence supporting the effectiveness and efficacy of SWPBIS as a means to improve the behavioural outcomes of all students, these positive outcomes largely depend on the actions of teachers. To this point, very limited research has been published that explores the experiences of teachers working in Australian schools currently implementing SWPBIS. The current study asked 206 Victorian teachers working in schools implementing SWPBIS two open-ended questions about the factors that they believed were facilitators or barriers to their ability to improve the behavioural outcomes of their students. The most commonly reported facilitators were availability of time, consistency of staff implementation of behaviour support, and adequate training. The most frequently identified barriers were a lack of time and inconsistent implementation. The practical and research implications of these preliminary qualitative findings are discussed.
An Estonian-Russian Language Club as a Venue for Grassroots Ethnic Integration
Authors: Astapova Anastasiya
Published: May 2021

One third of Estonian residents identify Russian as their mother tongue, and despite having lived in Estonia for decades, many of them are not fluent in the Estonian language and choose to remain stateless rather than obtain Estonian citizenship by passing the state language exam. Ethnic segregation in Estonia continues to be a matter of bitter political debate, not least in the context of tensions with neighboring Russia and pressure from the EU to solve the problem. While a lot of state resources are being spent on what the Estonian-speaking public often perceives as vain attempts at integration of Russophones, several civil society initiatives have recently emerged to provide platforms for informal language socialization. In this article, I focus on the case study of theKeelegrupp(Language Group) which provides a venue for interaction between Estonian and Russian speakers, to analyze what makes this informal organization more successful at responding to the challenges of language-based segregation than professional, state-funded initiatives. Ethnographic documentation and analysis of this initiative is essential given that its experience and structure are highly applicable for and transferrable to many other states with similar situations of ethnic segregation, not the least the neighboring Baltic countries.
Species distribution modeling reveals the ecological niche of extinct megafauna from South America
Authors: Araújo Thaísa , Machado Helena , Mothé Dimila , dos Santos Avilla Leonardo
Published: May 2021

Climatic and environmental changes, as well as human action, have been cited as potential causes for the extinction of megafauna in South America at the end of the Pleistocene. Among megamammals lineages with Holarctic origin, only horses and proboscideans went extinct in South America during this period. This study aims to understand how the spatial extent of habitats suitable for Equus neogeus and Notiomastodon platensis changed between the last glacial maximum (LGM) and the middle Holocene in order to determine the impact that climatic and environmental changes had on these taxa. We used species distribution modeling to estimate their potential extent on the continent and found that both species occupied arid and semiarid open lands during the LGM, mainly in the Pampean region of Argentina, southern and northeastern Brazil, and parts of the Andes. However, when climate conditions changed from dry and cold during the LGM to humid and warm during the middle Holocene, the areas suitable for these taxa were reduced dramatically. These results support the hypothesis that climatic changes were a driving cause of extinction of these megamammals in South America, although we cannot rule out the impact of human actions or other potential causes for their extinction.
Effects of operational sex ratio, mating age, and male mating history on mating and reproductive behavior inGrapholita molesta
Authors: Kong Weina , Wang Yi , Guo Yongfu , Chai Xiaohan , Li Jie , Ma Ruiyan
Published: May 2021

The short-lived polygamous mothGrapholita molesta(Busck) is an important fruit pest worldwide. Trapping males by synthetic female sex pheromones is not an effective reproductive control strategy. It is important to improve this technology by understanding the mating system ofG.molesta. This study investigated mating opportunities and fertile egg production by altering the operational sex ratio, mating age, and male mating history in repeated single mating and multiple mating in the two sexes. Our results showed that the mating and reproductive parameters of virgin males were affected by the number and age of virgin females. Males preferred a female number ≤three-fifths of the male number or ≤2-day-old females, while they discriminated against a female number ≥three times of the male number or ≥5-day-old females. On the other hand, the mating and reproductive parameters of virgin females were affected by repeated single mating and especially multiple mating under different male mating histories. Females preferred once-mated males and discriminated against virgin males. These results indicated that mating systems including more and older virgin females for virgin males and different virgin males for virgin females may be suitable for suppressingG.molestapopulations. Hence, these results revealed that preventing mating of virgin adults by synthetic female sex pheromones should be most effective in controllingG.molesta.
Influence of temperature on the development and reproduction of Cinara cedri (Hemiptera: Aphidoidea: Lachninae)
Authors: Ji Yingchao , Li Guohua , Zhou Chenggang , Yin Shuyan
Published: May 2021

Temperature is one of the main factors affecting insect growth, development and reproduction. The effects of temperatures (10, 15, 20, 25 and 30°C) on the development and reproduction of Cinara cedri Mimeur (Hemiptera: Aphidoidea: Lachnidae) fed on Cedrus deodara (Roxb.) G. Don were evaluated in this study. With the increase of temperature from 10 to 30°C, the development duration at different development stages gradually shortened. There was a significant positive correlation between the developmental rates and temperature, following a quadratic regression model. The lower developmental threshold temperature (C) and effective accumulated temperatures (K) for completing a generation were 4.13°C and 263.4 degree-days, respectively. The highest fecundity was observed at 20°C with 25.74 first-instar nymphs/female. Both the highest intrinsic rate of increase (r, 0.11 ± 0.03) and net reproduction rate (R0, 19.06 ± 2.05) were observed at 20°C, whereas the lowest values of r (0.05 ± 0.01) at 10°C and R0 (5.78 ± 0.88) at 30°C were observed. The results suggest that temperature significantly affects the biology of C. cedri and the optimal temperature for its development is 20°C.

Undeniably, one of the rare characteristics of James C. Scott's scholarship is that his analytical insights are widely recognized in many fields beyond political science and Asian studies. Scott's contributions to the vast literatures of agrarian and environmental studies, the theory of hegemony and resistance, development studies, postcolonial studies, state formation, and anarchism, to name just a few, are recognized by scholars of diverse disciplines as new standards that challenge widely accepted assumptions and theories and reveal underappreciated aspects and untold narratives of social history—particularly for those who, under normal conditions, do not raise their voice and did not have letters to leave records.
Consumer perceptions on the origin of infant formula: a survey with urban Chinese mothers
Authors: Shan Liran Christine , Li Chenguang , Yu Zhongyi , Regan Áine , Lu Ting , Wall Patrick
Published: May 2021

The consumer survey reported in this research paper aims to understand how Chinese mothers learn about and confirm the origin of powdered infant formulas (henceforward formulas), their knowledge level and preferences between formulas from different origins. With globalization, dairy companies can source ingredients for domestic production and manufacture finished products across the world. Chinese consumers are now facing a variety of formulas with different brand origin, main ingredient origin (‘nai yuan’), manufacturing origin, and country-of-purchase. Drawing on a large representative sample of Chinese mothers who have purchased formulas, we found that most of them had intensively engaged in learning about and confirming formulas' origin through different strategies. However, they may not interpret related cues correctly: a majority of Chinese mothers incorrectly considered the ‘main ingredient origin’ as the ‘manufacturing place’ and could not necessarily recognize between ‘foreign’ and ‘domestic’ brands. Among formulas from different origins, authentic foreign branded, produced and packaged formulas showed a high popularity in Tier 1 & 2 cities and among more knowledgeable consumers. In low-tier cities, these products were equally popular as domestically branded and produced formulas using imported milk powders and other ingredients. Formulas directly acquired from overseas markets through unofficial channels were least favoured by consumers. The study shows that Chinese consumers' previous one-sided endorsement towards foreign formulas appears to have weakened. Decisions made by formula companies on the origin of the main ingredient and the place of manufacture would influence product attractiveness, and the segments of Chinese consumers to target.
Biases in the production of knowledge on ecosystem services and poverty alleviation
Authors: Corbera Esteve , Maestre-Andrés Sara , Calvet-Mir Laura , Brockington Dan , Howe Caroline , Adams William M.
Published: May 2021

Research into the relationship between ecosystem services and human well-being, including poverty alleviation, has blossomed. However, little is known about who has produced this knowledge, what collaborative patterns and institutional and funding conditions have underpinned it, or what implications these matters may have. To investigate the potential implications of such production for conservation science and practice, we address this by developing a social network analysis of the most prolific writers in the production of knowledge about ecosystem services and poverty alleviation. We show that 70% of these authors are men, most are trained in either the biological sciences or economics and almost none in the humanities. Eighty per cent of authors obtained their PhD from universities in the EU or the USA, and they are currently employed in these regions. The co-authorship network is strongly collaborative, without dominant authors, and with the top 30 most cited scholars being based in the USA and co-authoring frequently. These findings suggest, firstly, that the production of knowledge on ecosystem services and poverty alleviation research has the same geographical and gender biases that characterize knowledge production in other scientific areas and, secondly, that there is an expertise bias that also characterizes other environmental matters. This is despite the fact that the research field of ecosystem services and poverty alleviation, by its nature, requires a multidisciplinary lens. This could be overcome through promoting more extensive collaboration and knowledge co-production.
When the Music Stopped: Reactions to the Outbreak of World War I in an Austrian Province
Authors: Cole Laurence , Horejs Marlene , Rybak Jan
Published: May 2021

The article analyzes reactions to the outbreak of World War I in the Habsburg Crownland of Salzburg. Based on a detailed examination of local sources, such as diaries, memoirs, church and gendarmerie chronicles, regional newspapers, and administrative records, the study sheds light on the complexity of responses and emotions elicited during the summer of 1914. Engaging with recent historiography on the question of “war enthusiasm” and the “August experience,” the ensuing analysis allows for profound insights into how the local population reacted to the news of the Sarajevo assassinations, Austria-Hungary's ultimatum to Serbia, and the subsequent declaration of war, mobilization, and the first weeks of the conflict. The article highlights the role of the press, governmental policies, and repression as key factors in creating an agitated atmosphere to which people responded in different ways, depending on age, class, gender, and the urban–rural divide. At times, frenzied patriotic mobilization occurred alongside not only a widespread acceptance of the obligation to do one's duty, but also—and equally—great uncertainty and anxiety. This highlights the complexities of public reactions in the summer of 1914, thereby challenging from a regional historical perspective the notion of an “enthusiastic” welcoming of the war.
Multiplicatively badly approximable matrices up to logarithmic factors
Authors: FREGOLI REYNOLD
Published: May 2021

Let \[||x||\] denote the distance from \[x \in \mathbb{R}\] to the nearest integer. In this paper, we prove a new existence and density result for matrices \[A \in {\mathbb{R}^{m \times n}}\] satisfying the inequality

\[\mathop {\lim \inf }\limits_{|q{|_\infty } \to + \infty } \prod\limits_{j = 1}^n {\max } \{ 1,|{q_j}|\} \log {\left( {\prod\limits_{j = 1}^n {\max } \{ 1,|{q_j}|\} } \right)^{m + n - 1}}\prod\limits_{i = 1}^m {{A_i}q} > 0,\]

where q ranges in \[{\mathbb{Z}^n}\] and Ai denote the rows of the matrix A. This result extends previous work of Moshchevitin both to arbitrary dimension and to the inhomogeneous setting. The estimates needed to apply Moshchevitin’s method to the case m > 2 are not currently available. We therefore develop a substantially different method, based on Cantor-like set constructions of Badziahin and Velani. Matrices with the above property also appear to have very small sums of reciprocals of fractional parts. This fact helps us to shed light on a question raised by Lê and Vaaler on such sums, thereby proving some new estimates in higher dimension.
Experimental study on the effects of a single simulator-based bridge resource management unit on attitudes, behaviour and performance
Authors: Röttger Stefan , Krey Hannes
Published: May 2021

The objective of this work was to assess whether the implementation of a bridge resource management (BRM) unit into the simulator-based nautical training of the German Navy is effective in improving non-technical skills and navigation performance. To this end, questionnaire data, observations of behaviour and performance outcomes were compared between a control group and an experimental group. Data of 24 bridge teams (126 sailors) were used for the analyses. Ten teams received BRM training and 14 teams served as the control group with unchanged simulator training. Reactions to simulator training were positive in both groups but more favourable in the control group. In the BRM group, significantly more positive attitudes towards open communication and coordination, more frequent sharing of information and fewer collisions were found than in the control group. Effect sizes were rather small. This may be due to the limited scale of the BRM unit, which consisted of only one instruction-training-feedback cycle. The extension of BRM-related feedback to all simulator runs of the nautical training can be expected to produce larger effects on attitudes, behaviour and performance.
Good-bye to all that: COVID-19 and the transformations of cultural heritage
Authors: Silberman Neil Asher
Published: May 2021

Economists, political scientists, and journalists around the world have suggested that the COVID-19 pandemic will have long-term effects on twenty-first-century global society. As a precipitating factor in the final collapse of the post-1945 world order, the pandemic has been seen as an epochal turning point in human history. This article will examine the long-term effects that the pandemic may have on the protection and promotion of cultural heritage, which has become a major economic and political undertaking in the post-World War II era, with earlier roots in elite aesthetics and the rise of mass tourism in the nineteenth century. This article will identify some dramatic changes in economic activity and politics that may transform the social role of cultural heritage in the coming decades.
Heritage hands and tastes of the pandemic
Authors: Tracy Megan
Published: May 2021

The revitalization of fermentation projects during COVID-19 raises questions about the preservation of the pandemic’s material and ephemeral effects – a topic that heritage policy is well equipped to engage. These activities also emphasize the necessity of engaging with heritage practices as a kind of care, encompassing both methods of safekeeping and practices of empathy. In addition, heritage ferments prove “good to think” around themes of loss and preservation, the interpretation of novel viruses through traditional food practices, and the coupling of heritage to microbes. Connecting microbes with heritage allows us to consider points of overlap: as bearers of patrimony with cultural and material lineages, as central to heritage tastes, and as open to geographical indications or other protections to further a kind of microbial resource management. Despite the pandemic’s devastating impact, consideration of heritage ferments points to both emancipatory and constraining outcomes for our post-pandemic future.

Ianus Augustus, Caput Viae (Mengíbar, Spain): An interprovincial monumental border in Roman Hispania
Authors: Bellón Ruiz Juan Pedro , Lechuga Chica Miguel Ángel , Moreno Padilla María Isabel , Gutiérrez-Rodríguez Mario
Published: May 2021

Recent research undertaken as part of the Iliturgi Project has located the remains of an Early Imperial building complex linked to the Via Augusta. They include the foundations of an arch and a monumental platform whose size and characteristics allow it to be identified as the Ianus Augustus, a monumental complex near the River Baetis that marked the limit between the Roman provinces of Baetica and Tarraconensis. Its location makes it a reference point for our knowledge of the ancient geography of Hispania and for understanding Roman interprovincial frontiers. Geophysical prospections in its surroundings have also revealed the possible remains of a bridge across the river.

Objective:

To assess the feasibility of percutaneous transcatheter device closure of ventricular septal defects in children weighing less than 10 kg.

Background:

Although percutaneous transcatheter device closure of ventricular septal defect is a well-established method of treatment in older children and adolescents, there is limited data on device closure in small children weighing less than 10 kg. We present our institutional experience of transcatheter VSD closure in children weighing less than 10 kg.

Method:

Medical records were reviewed for 16 children, who were selected for device closure of ventricular septal defects based on the inclusion criteria.

Results:

Out of 65 patients with a diagnosis of ventricular septal defect, 16 children less than 10 kg were attempted for percutaneous device closure. In 13 patients, the device was successfully released, and 3 patients needed surgical closure of the defect. Mean age and weight of the patients were 17.3 ± 12.7 months and 6.8 ± 3.2 kg, respectively. Mean defect size was 6 mm (range 3–10). There was no incidence of device embolisation or heart block or death. Five patients had residual left-to-right shunt immediately after the device release, which got closed by the first month’s follow-up. We had one accidental perforation of right ventricular free wall at the time of crossing of the defect, which was successfully repaired surgically.

Conclusion:

Percutaneous device closure of ventricular septal defect in small children with weight below 10 kg is feasible with good short-term outcome. Careful patient selection is essential for procedural success and to avoid complications.
The Standard Doctrine of Creation in Zoroastrian Pahlavi Texts
Authors: AHMADI AMIR
Published: May 2021

The main scheme of creation in Zoroastrian Pahlavi literature is adopted from the Young Avesta. In this scheme Ohrmazd creates the world in the manner of a skillful craftsman who conceives of the form of his product and then fashions it in matter. The number of the constituents of the world and the sequence in which they are created are already fixed in the Avesta. Pahlavi authors draw on Greek philosophical tradition to rationalise their account of the creation of the world. The article also explores some of the complications that their philosophical elaboration of the Avestan scheme occasions.

Maternal obesity increases the risk of nonalcoholic fatty liver disease (NAFLD) in offspring. The Roux-en-Y gastric bypass (RYBG) is effective for achieving weight loss and ameliorates NAFLD. To determine whether these benefits are maintained after pregnancy and/or lactation, and whether they modulate hepatic morphofunction in the next generation, we evaluated hepatic lipid metabolism in Western diet (WD)-obese female rats that underwent RYGB and in their F1 offspring at adulthood. Female Wistar rats consumed a WD from 21 to 130 days of age, before being submitted to RYGB (WD-RYGB-F0) or SHAM (WD-SHAM-F0) operations. After 5 weeks, these females were mated with control male breeders, and the male and female F1 offspring were identified as WD-RYGB-F1 and WD-SHAM-F1. WD-RYGB-F0 dams exhibited lower serum lipids levels, but severe hepatic steatosis and pathological features of advanced liver injury. The hepatic proteins involved in lipogenesis were reduced in WD-RYGB-F0, as were the genes related to β-oxidation and bile acids (BAs). Although the female and male WD-RYGB-F1 groups did not exhibit hepatic steatosis, the livers of female WD-RYGB-F1 demonstrated higher amounts of lipogenic genes and proteins, while male WD-RYGB-F1 presented a similar downregulation of lipogenic factors to that seen in WD-RYGB-F0 dams. In contrast, maternal and offspring groups of both sexes displayed reductions in the expressions of genes involved in BAs physiology and gluconeogenesis. As such, RYGB aggravates NAFLD after pregnancy and lactation and induces a gender-dependent differential expression of the hepatic lipogenesis pathway in offspring, indicating that female WD-RYGB-F1 may be an increased risk of developing NAFLD.

A sudden stratospheric warming (SSW) is an extremely rare event in the Southern Hemisphere (SH), but occurred in early September 2019. From the Antarctic meteor radar (MR) stations, Davis (68.6˚S, 77.9˚E) and King Sejong Station (62.2˚S, 58.8˚W), quasi 10‐day oscillations were clearly observed in the zonal mesospheric winds before the central date (DOY 253) of the SSW. From the northern low‐latitude Tirupati (13.6˚N, 79.4˚E) MR, a strong wave activity with a period of ∼6 days was detected in the zonal winds right after the central date. This oscillation is also seen in the geopotential height measurements from the Microwave Limb Sounder (MLS) on board the Aura satellite near the Tirupati region. To elucidate the possible source of the quasi 6‐day wave (Q6DW), we use a specified dynamics version of the Whole Atmosphere Community Climate Model (SD‐WACCM) constrained by the reanalysis data from the surface to 50 km. The simulation results show that the amplitude of the westward and equatorward propagating Q6DW was enhanced after the SSW central date in the MLT region, and the Q6DW can be attributed to the baroclinic/barotropic instability in the SH high‐latitude mesosphere where the divergence of Eliassen‐Palm flux occurred. Thus, we suggest that the Q6DW activity observed by the Tirupati MR and MLS originated from the SH high‐latitude mesospheric region. Both the observation and the simulation results clearly demonstrate that the 2019 SH SSW affected not only the high‐latitude MLT region but also the low‐latitude MLT region.
Transverse Mixing in Rivers With Longitudinally Varied Morphology

Improving the quantification of the transverse mixing coefficient in rivers is essential for a better estimation of pollutant dispersion. This coefficient is evaluated from tracing experiments or from semi‐empirical equations assuming uniform flow conditions. This assumption, verified for laboratory experiments, is questionable for river studies. For example, piedmont rivers exhibit nonuniform flows due to their longitudinal morphological variations. This work aims at studying the longitudinal variability of the transverse mixing coefficient in a river with longitudinally varied morphology and the overlooked impact of the flow nonuniformity on the coefficient’s values. Tracing experiments were conducted in the Durance River in France using slug injections and concentration measurements made at the cross‐sections delineating homogeneous sub‐reaches. Using the well‐known 1D transverse diffusion model, values of the transverse mixing coefficient are determined for all consecutive sub‐reaches. These values substantially vary along the studied river, with stronger mixing efficiency at pools and complex riffles and weaker mixing efficiency in straight sub‐reaches with emerging obstacles. The dimensionless transverse mixing coefficient is strongly related to a parameter quantifying the deviation from flow‐uniformity, i.e., indicating flow acceleration, deceleration or a succession of both within the sub‐reaches. While usual formulas from the literature fail to predict our empirical results, a new equation including the flow nonuniformity parameter fits our experimental data with high accuracy. After further validation, such equation may be used for predicting the transverse mixing coefficient in rivers with longitudinally varied morphology.
Global Simulation of the Jovian Magnetosphere: Transitional Structure From the Io Plasma Disk to the Plasma Sheet

Jupiter has a strong magnetic field, and a huge magnetosphere is formed through the solar wind‐Jupiter interaction. The generated magnetosphere–ionosphere system is reproduced based on the 9‐component Magnetohydrodynamics (MHD) and the current conservation in the ionosphere. Assuming Io plasma emission rate 1.4 t/sec, this paper reproduces self‐consistently global magnetic configuration, generations of the field‐aligned current (FAC) and aurora, formation of the Io plasma disk at 8–20 RJ, plasma corotation, instability in the plasma disk, transition from the Io plasma disk to the plasma sheet at 20–150 RJ, and the plasmoid ejection. The rotating Io plasma in the disk forms instabilities that promotes radial diffusion. H+ is supplied from the ionosphere along high‐latitude magnetic field lines and mixed with heavy ions around 15–20 RJ. Beyond 20 RJ, mixed plasma diffuses further outward by the centrifugal force that can exceed magnetic tension. In the ionosphere, the main oval occurs at 13.7°–15.5° colatitude. The Io disk is inner side of magnetic field lines traced from the low‐latitude edge of the main oval. Along magnetic field lines, the main oval is mapped from the outer edge of the Io disk to the entire plasma sheet accompanying rotation delay. Due to the corotation limit, convection is accompanied by plasmoid ejection. Back reaction of plasmoid ejection affects even transport process in the Io disk. The downward FAC occurs in the polar cap showing variability. The region of externally driven Dungey convection seems quite narrow.
Slimy partners: the mucus barrier and gut microbiome in ulcerative colitis

Ulcerative colitis (UC) is a chronic recurrent intestinal inflammatory disease characterized by high incidence and young onset age. Recently, there have been some interesting findings in the pathogenesis of UC. The mucus barrier, which is composed of a mucin complex rich in O-glycosylation, not only provides nutrients and habitat for intestinal microbes but also orchestrates the taming of germs. In turn, the gut microbiota modulates the production and secretion of mucins and stratification of the mucus layers. Active bidirectional communication between the microbiota and its ‘slimy’ partner, the mucus barrier, seems to be a continually performed concerto, maintaining homeostasis of the gut ecological microenvironment. Any abnormalities may induce a disorder in the gut community, thereby causing inflammatory damage. Our review mainly focuses on the complicated communication between the mucus barrier and gut microbiome to explore a promising new avenue for UC therapy.
