Authors: Koens Sarah , Strauß Annette , Klein Jens , Schäfer Ingmar , von dem Knesebeck Olaf 
Published: August 2022

Background
There is evidence that perceived urgency of medical complaints is associated with emergency care utilization. Patients’ perception of urgency can differ from physicians’ assessment. This study explored public perceptions of urgency of severe cases of COVID-19 and inflammatory gastrointestinal disease and analyzed variations in perceptions of urgency by characteristics of the afflicted person in the vignettes and sociodemographic characteristics of respondents.

Methods
Vignettes with severe symptoms of either inflammatory gastrointestinal disease or COVID-19 with comparable urgency of treatment were used in a telephone survey in Germany (N = 1,207). Besides disease, the vignettes varied in terms of sex, age (child, middle-aged person, old person) and daytime (Tuesday morning, Tuesday evening). Respondents were asked to rate the urgency of the reported symptoms with four items. A sum scale was computed. Variations in perceptions of urgency according to vignette characteristics and sociodemographic characteristics of the respondents (sex, age, educational level, migration background, children (yes/no) and personal affliction) were analyzed using a linear regression model.

Results
In terms of vignette characteristics, multivariate analysis showed a lower estimated urgency for males, as well as for the middle-aged and aged persons, compared to the child vignettes, and for COVID-19, compared to inflammatory gastrointestinal disease. Regarding the characteristics of the respondents, estimated urgency increased with age and was lower among respondents, who were previously affected by the symptoms themselves.

Conclusion
Although urgency in the vignettes was comparable, variations in estimated urgency by age and sex of the afflicted person and the described disease as well as age and personal affliction of the respondents were identified. This could result in an inadequate health care service utilization. Therefore, variations in public perceptions of urgency should be considered in the planning of public campaigns on adequate health care services utilization.
Pointwise A Posteriori Error Control of Discontinuous Galerkin Methods for Unilateral Contact Problems
Authors: Khandelwal Rohit , Porwal Kamana 
Published: August 2022

Abstract
In this article, we derive a reliable and efficient a posteriori error estimator in the supremum norm for a class of discontinuous Galerkin (DG) methods for the frictionless unilateral contact problem between two elastic bodies.
The proposed error estimator generalizes the basic residual type estimators for the linear problems in linear elasticity taking into account the nonlinearity on a part of the boundary.
The analysis hinges on the super- and sub-solutions constructed by modifying the discrete solution appropriately, and it is carried out in a unified manner which holds for several DG methods.
The terms arising from the contact stresses in the error estimator vanish on the discrete full contact set.
We illustrate the performance of the proposed error estimator via several numerical experiments in two dimensions.

Abstract
2,6-Methylacylnaphthalene is an important organic chemical raw material, mainly used as a precursor for synthesizing polyethylene 2,6-naphthalene dicarboxylate (PEN). The heterogeneous catalyst molecular sieve catalyzes the acylation of 2-methylnaphthalene to synthesize β,β-methylacylnaphthalene, which has good activity, is green and environmentally friendly, with simple post-treatment. Different molecular sieves and reaction solvents were selected, and Hβ molecular sieves were more suitable for the acylation reaction of 2-methylnaphthalene. The reaction results were better when sulfolane was used as a solvent in this paper. The catalytic performances of citric acid-modified Hβ molecular sieve (SiO2/Al2O3 of 25) and unmodified molecular sieve were investigated and compared. The results showed that modification with low-concentration citric acid increased the amount of mediate strong acid and Bronsted acid, the specific surface area, pore volume, and pore size of Hβ zeolite. When the concentration of citric acid was 0.3 mol·L−1, the modification time was 48 h and the calcination at 550°C for 3 h had the best catalytic activity. By further optimizing the acylation process, the conversion rate of 2-methylnaphthalene increased to 88.82%, and the yield of β,β-methyl propyl naphthalene increased to 82.12%.
St’át’imcets frustratives as not-at-issue modals
Authors: Davis Henry , Matthewson Lisa 
Published: August 2022

Abstract
This paper provides an analysis of the ‘frustrative’ marker séna7 in St’át’imcets (Lillooet Salish), and compares it to similar elements cross-linguistically. Séna7 appears in a range of discourse contexts, including when events have an unexpected outcome, fail to continue, or fail to take place optimally. We argue that séna7 felicitously applies to a proposition p only if there is a salient true proposition q and the speaker did not expect p and q to both be true. Séna7 encodes epistemic modality, refers only to the speaker’s epistemic state (ignoring the common ground), and has no effect on at-issue truth conditions (séna7(p) entails p). We show that séna7 provides a diagnostic for distinguishing between entailments and implicatures in the language, and a clear diagnostic for the distinction between futures and prospective aspects. We compare séna7 with similar elements in Tohono O’odham, Kimaragang and Tagalog. We argue that séna7 and the Kimaragang frustrative can be captured by the same analysis once independent features of their tense/aspect systems are taken into account. Following Kroeger (2017. Frustration, culmination and inertia in Kimaragang grammar. Glossa: A Journal of General Linguistics 2(1). 56. 1–29), but pace Copley and Harley (2014. Eliminating causative entailments with the force-theoretic framework: The case of the Tohono O’odham frustrative cem. In Bridget Copley & Fabienne Martin (eds.), Causation in grammatical structures (Oxford Studies in Theoretical Linguistics 52), 120–151. Oxford: Oxford University Press), we argue that frustratives should not be unified with non-culminating accomplishments, and can be analyzed without appealing to causality or efficacy.

Abstract
The potential effect of nano TiO2 in poly(vinylidene fluoride-hexafluoropropylene) (PVDF-HFP) based polymer electrolyte and their application in a dye sensitized solar cell have been investigated. The solution casting process was used for fabrication of nano TiO2 loaded in Mg
2+
ion based PVDF-HFP solid polymer electrolyte (SPE), and characterized using conductivity, scanning electron microscopy (SEM), X-ray diffraction (XRD) and photovoltaic studies. XRD investigations reveal the broadening of specific peaks, which shows the occurrence of α, β and γ polymorphous phase transitions that commence the amorphous character and ion mobility. The SEM pictures revealed an interconnecting network of micro-porous nature, and an average diameter of the pores of ∼0.38 µm was obtained by using Gaussian curve fitting. Ion transport is facilitated by the high concentration of pores, which is responsible for the efficient absorption of a significant amount of electrolyte. The photovoltaic characteristics of dye sensitized solar cell (DSSC) estimated efficiency (η) is 9.9999%, and the fill factor is 0.84. Furthermore, the stability performance of the nanocomposite polymer electrolyte was improved and sufficient for use over an extended length of time, suggesting potential applications as a separator in solid state ionic conductors.

Published: August 2022

Abstract

Objectives
The impact of disasters on individual and community health can be extensive. As such, there exists the need to establish recovery measures that provides support psychologically and with additional mental health services and resilience building for affected people and their communities. Nature-led recovery is one such approach that has the ability to positively impact the mental health of people and their communities after a disaster. Nature-led recovery focuses on the social, economic and environmental recovery through activities that connect people and their communities to nature and the natural environment with the aim to foster recovery after a disaster. Nature-led recovery initiatives support the connection of people with nature and the natural environment to support such recovery processes. This review considers both community and government-led responses pertaining to nature-led recovery. The aim of this review is to systematically explore the literature on the impact of nature-led recovery initiatives on individual and community health following a disaster.

Content
This review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) following a three-step process of planning, conducting and reporting the review. At least three authors reviewed all eligible articles.

Summary
There was significant methodological heterogeneity between the sources identified (n=9). A narrative synthesis identified five key themes; A symbol of loss; Nature: the provider; Fostering community connectedness; Spiritual and emotional nourishment; and Regeneration leads to recovery.

Outlook
The positive benefits from nature-led recovery initiatives provide an opportunity to promote community connectedness and resilience following a disaster. Further research is needed to explore the implementation and evaluation of these initiatives for community recovery.

Published: August 2022

In search of reinvention in the middle of the pandemic, an equipment adapted from a system that controls morph for indoor environments that have air conditioners is proposed. This paper presents a study via computational modeling to test the effect of electrical resistance as an air filter against SARS-CoV-2. The mode of transmission of SARS-CoV-2 includes, for example, transmission via contact, droplets, and aerosols present in indoor humidity. Therefore, aerosol spread of SARS-CoV-2 is similar to the indoor spread of the morph. The result shows that the system works by eliminating the humidity in the air containing SARS-CoV-2. What we are trying to demonstrate is that an electrically resistive filter controls the spread of the virus in air up to 10 cubic meters in size indoors. This system does not replace existing filters, but is a piece of equipment to help control SARS-CoV-2.

Published: August 2022

Abstract:
The COVID-19 pandemic and the mandated cessation of surgical procedures for a substantial portion of the 2020 year placed tremendous strain, both clinically and financially, on the health-care system in the United States. As a surgical specialty that accounts for nearly a quarter of all hospital net income, the revenue recovery of orthopaedic service lines (OSLs) is of particular importance to the financial recovery of their broader health-care institutions. In this American Orthopaedic Association (AOA) symposium report, the OSL leaders from 4 major academic medical institutions explain and reflect on their approaches to address their revenue deficits. Cost-reduction strategies, such as tightening budgets, adopting remote-work models, and limiting costs of human capital, were vital to stabilizing departmental finances at the onset of the pandemic, while strategies that focused on expanding surgical volume, such as those that improve efficiency in clinical and surgical settings, were important in growing revenue once elective procedures resumed. Institutional policy, payer administrative procedures, and the overall context of an ongoing public health crisis all placed limitations on recovery efforts, but engaging relevant stakeholders and working with available resources helped OSLs overcome these limitations. Due to clear strategic actions that were taken to address their deficits, each OSL represented in this AOA symposium saw substantial improvement in its year-end financial performance compared with its financial status at the end of the period of mandatory cessation of elective surgical cases.

Does urban isolation produce instability in a gliding mammal?
Authors: Marks Anita Jane , Goldingay Ross L 
Published: August 2022

Abstract
Small populations are at a higher risk of extinction and are likely to need management intervention. Successful management however often relies on sufficient long-term demographic data to determine whether apparent declines are natural fluctuations or rather the product of threatening processes. In this study we monitored a small urban population of squirrel gliders (Petaurus norfolcensis) in Queensland, Australia over a 16-year period. A reference population situated in a larger forest patch was also monitored to identify whether its demographic trends were similar. We found evidence of a decline within the small population but not the reference population over the monitoring period. We suggest the influence of multiple factors may have led to the decline, but ultimately the genetic condition of the small population may be responsible. Understanding demographic trends is important for providing context for management interventions of small populations, however identifying the causes of declines is needed for successful management. This species provides a useful case study for small urban populations, and particularly for arboreal mammals.
Reinfection risk and vaccination effectiveness against Omicron
Authors: Du Jiaxing , Zhao Yanji , He Daihai 
Published: August 2022

Abstract
Omicron (B.1.1.529) variant has spread worldwide rapidly with largely evading immunity. The effectiveness of antibodies produced by prior infections with other SARS-COV-2 lineages or by vaccination against Omicron raises concerns.
Natural infection induces strong protection against reinfection with the Alpha (B.1.1.7), Beta (B.1.351), and Delta (B.1.617.2) variants. When Omicron variant first emerged in South Africa, it is estimated that hazard ratio for reinfection versus prior infection was 2.39, much higher than 0.75 (wave2) and 0.71 (wave3) in south Africa. Based on several studies from UK and Qatar, there is a unified conclusion that Omicron induced a higher risk of reinfection compared with Delta and other previous variants. Protection against reinfection with Omicron range from 19% to 56% in different studies. Vaccine induced immunity usually peaks two weeks after second dose. After that, a substantial waning of VE is widely observed. For Delta and previous variants, VE against infection six months after second dose ranged from 53.8% to 77%. Estimates of VE against Omicron are gained from several countries, including England, Denmark, South Africa ,Canada and Israel. Genarally a substantial decrease of VE was observed as time flow, even negative VE was observed in Canada and England.

Abstract
The immunoaffinity isolation of neuron-derived extracellular vesicles (NDEVs) from blood by targeting the neuronal protein L1CAM has been widely adopted to provide peripheral biomarkers for brain disorders. However, compelling evidence for the presence of L1CAM on NDEVs at the single-EV level has been missing. Here, we demonstrate that L1CAM co-localizes with EV-characteristic and neuronal markers in plasma EVs, and quantify the enrichment achieved after L1CAM immunoprecipitation, validating the NDEV isolation methodology.
Identifying key players in a network of child exploitation websites using Principal Component Analysis
Authors: Movahedi F. , Frank R. 
Published: August 2022

Abstract
One of the main objectives of this study is to help prioritize targets for law enforcement by analyzing online websites hosting child exploitation material and finding key players within. Key players are defined as the websites which display a combination of high connectivity and a lot of hardcore material and would provide the most disruption in a network if they were to be removed. In this study, various strategies based on Principal Component Analysis are presented to identify those nodes that act as the key players in an online child exploitation network. For evaluating the results of these strategies, we consider the results of various attack strategies. The measures for evaluation are the density, clustering coefficient, average path length, diameter and the number of connected components in the resulted network. The results show that the strategies proposed are more successful at reducing all of the outcome measures than existing strategies.
