Investigation of the Transmission Loss Behavior of an Advanced Grid-Stiffened Structure
Authors: Vipperman Jeffrey S. , Li Deyu , Avdeev Ilya 
Published: November 2021

Abstract
The vibroacoustic behavior of an advanced grid-stiffened (AGS) composite structure which is reminiscent of a mock-scale fairing has been investigated. Both finite element analysis (FEA) and experimental modal analysis have been performed and the results corroborated. The lightly-coupled structurally-dominant modes and acoustically-dominant modes can be used to determine the structural acoustic coupling coefficients for the fairing. In addition, the certain critical structural acoustic frequencies have been computed. These results can be assimilated in order to provide insight into the theoretical performance limits of various potential transmission control mechanisms, including geometry or property tuning, the inclusion of passive control materials, or the addition of secondary structural and/or acoustic control inputs.
“Extreme dinosaurs” and the continuing evolution of dinosaur paleoart
Authors: Allmon Warren D. 
Published: November 2021

ABSTRACT
Humans have made visual representations of what they think dinosaurs looked like since before the term and concept of “dinosaur” were first published in 1842. Over the next 175 years, these images have varied widely. The current era of dinosaur paleobiology began in the late 1960s and emphasized scientific and artistic conceptions of dinosaurs as more active and diverse in their metabolism, ecology, and behavior than previously thought. Over the past 25 years in particular, the rise of computer-generated images and the discovery of spectacularly preserved fossils from the Early Cretaceous of China and elsewhere have further revolutionized our understanding of the biology and external appearance (especially integument) of dinosaurs. Yet despite these innovations, dinosaur paleoart is still fundamentally shaped by the same basic set of influences that affected previous, now-discarded, images. These include (1) the fossils; (2) debates about which modern animals are the best bases for uniformitarian comparison with extinct taxa; (3) extrapolation (i.e., how far can we go from the known to the unknown); (4) the enabling effects of new artistic techniques; and (5) the ever-present pressures of the marketplace.
Mexico: Basement framework and pre-Cretaceous stratigraphy
Authors: Martens Uwe C. , Garza Roberto S. Molina 
Published: November 2021

ABSTRACTProvenance determinations of sediment deposited in circum–Gulf of Mexico basins rely on understanding the geologic elements present in the basement provinces located from northeast Mexico to Honduras. Relevant geologic features of these provinces are herein summarized in text and pictorial form, and they include the Huizachal-Peregrina uplift, western Gulf of Mexico, Huayacocotla, Zapoteco, Mixteca, Xolapa, Juchatengo, Cuicateco, Mixtequita, south-central Chiapas, southeast Chiapas, western Guatemala, central Guatemala, Maya Mountains, and the Chortis block. We recognized basement elements of local character that serve as fingerprints for specific source areas. However, many elements are ubiquitous, such as 1.4–0.9 Ga, high-grade metamorphic rocks that occur both as broad exposures and as inliers in otherwise reworked crust. Xenocrystic and detrital zircon of Mesoproterozoic age is very common and hence not diagnostic of provenance. Neoproterozoic rocks are very scarce in Mexican basement provinces. However, Ediacaran–Cambrian detrital zircon grains are found in Mexican Paleozoic strata; these were possibly derived from distant sources in Gondwana and Pangea. Ordovician–Silurian magmatism is present in approximately half the provinces; magmatic detrital zircon of such age is somewhat informative in terms of provenance. More useful populations are detrital zircon grains with Ordovician–Silurian metamorphic overgrowth, which seem to be mainly sourced from the Mixteca region or the southern Chiapas Massif. Devonian basement has only been discovered in the Maya Mountains of Belize, and detrital zircon of such age seems to be characteristic of that source. A similar case can be made about Carboniferous zircon and the Acatlán Complex, Middle Pennsylvanian zircon and Juchatengo plutons, and Late Triassic zircon and the basement exposed in central Guatemala. In all these cases, the age and geographic extent of the zircon source are restricted and serve as a distinct fingerprint. Plutons of Permian–Early Triassic age are widespread, and detrital zircon grains from them are rather nonspecific indicators of source area. Future dating of detrital white mica using 40Ar-39Ar could help in recognizing Carboniferous–Triassic schist from more restricted schist occurrences such as west Cuicateco (Early Cretaceous) and central Guatemala (Late Cretaceous).

BackgroundCatastrophic natural disasters and epidemics claim thousands of lives and have severe and lasting consequences, accompanied by human suffering. The Ebola epidemic of 2014–2016 and the current COVID-19 pandemic have revealed some of the practical and ethical complexities relating to the management of dead bodies. While frontline staff are tasked with saving lives, managing the bodies of those who die remains an under-resourced and overlooked issue, with numerous ethical and practical problems globally.MethodsThis scoping review of literature examines the management of dead bodies during epidemics and natural disasters. 82 articles were reviewed, of which only a small number were empirical studies focusing on ethical or sociocultural issues that emerge in the management of dead bodies.ResultsWe have identified a wide range of ethical and sociocultural challenges, such as ensuring dignity for the deceased while protecting the living, honouring the cultural and religious rituals surrounding death, alleviating the suffering that accompanies grieving for the survivors and mitigating inequalities of resource allocation. It was revealed that several ethical and sociocultural issues arise at all stages of body management: notification, retrieving, identification, storage and burial of dead bodies.ConclusionWhile practical issues with managing dead bodies have been discussed in the global health literature and the ethical and sociocultural facets of handling the dead have been recognised, they are nonetheless not given adequate attention. Further research is needed to ensure care for the dead in epidemics and that natural disasters are informed by ethical best practice.

IntroductionMyopia is the common cause of reduced uncorrected visual acuity among school-age children. It is more prevalent in urban than in rural areas. Although many myopia studies have focused on the effect of urbanisation, it remains unclear how visual experience in urban regions could affect childhood myopia. This study aims to investigate the incidence and prevalence of myopia among school-age children in urban and rural settings, thereby identifying the environmental factors that affect the onset and progression of myopia.Methods and analysisA school-based cohort study will be conducted. We will enroll all first-grade students from an urban (10 primary schools) and a rural (10 primary schools) regions of Zhaoqing city, China. Over 3-year follow-up period, students will receive detailed eye examinations annually and complete questionnaires about living habits and environment. In a 5% random subsample of the cohort, physical activity, light intensity and eye-tracking data will be obtained using wearable devices, and high-resolution macular images will be obtained by optical coherence tomography (OCT). The primary outcome is incident myopia, defined as myopia (spherical equivalent refractive of at least −0.5D) detected during follow-up among those without myopia at baseline.Ethics and disseminationEthics approval was obtained from the ethics committee of the Zhongshan Ophthalmic Center (number: 2019KYPJ171). Study findings will be published in a peer-reviewed journal.Trial registration numberNCT04219228.

ObjectiveTo describe the characteristics of contacts of patients with COVID-19 case in terms of time, place and person, to calculate the secondary attack rate (SAR) and factors associated with COVID-19 infection among contacts.DesignA retrospective cohort studySetting and participantsContacts of cases identified by the health department from 14 March 2020to 30 May 2020, in 9 of 38 administrative districts of Tamil Nadu. Significant proportion of cases attended a religious congregation.Outcome measureAttack rate among the contacts and factors associated with COVID-19 positivity.ResultsWe listed 15 702 contacts of 931 primary cases. Of the contacts, 89% (n: 14 002) were tested for COVID-19. The overall SAR was 4% (599/14 002), with higher among the household contacts (13%) than the community contacts (1%). SAR among the contacts of primary cases with congregation exposure were 5 times higher than the contacts of non-congregation primary cases (10% vs 2%). Being a household contact of a primary case with congregation exposure had a fourfold increased risk of getting COVID-19 (relative risk (RR): 16.4; 95% CI: 13 to 20) than contact of primary case without congregation exposure. Among the symptomatic primary cases, household contacts of congregation primaries had higher RR than household contacts of other cases ((RR: 25.3; 95% CI: 10.2 to 63) vs (RR: 14.6; 95% CI: 5.7 to 37.7)). Among asymptomatic primary case, RR was increased among household contacts (RR: 16.5; 95% CI: 13.2 to 20.7) of congregation primaries compared with others.ConclusionOur study showed an increase in disease transmission among household contacts than community contacts. Also, symptomatic primary cases and primary cases with exposure to the congregation had more secondary cases than others.

ObjectivesThe purpose of this study was to examine the perspectives of primary care physicians in Texas around vaccine acceptance and potential patient barriers to vaccination. National surveys have shown fluctuating levels of acceptance for COVID-19 vaccination, and primary care physicians could play a crucial role in increasing vaccine uptake.DesignThis study employed a cross-sectional anonymous survey design to collect data using an online questionnaire. Participants were asked about vaccination practices and policies at their practice site, perceptions of patient and community acceptance and confidence in responding to patient vaccine concerns.SettingFrom November 2020 to January 2021, family medicine physicians and paediatricians completed an online questionnaire on COVID-19 vaccination that was distributed by professional associations.ParticipantsThe survey was completed by 573 practising physicians, the majority of whom identified as family medicine physicians (71.0%) or paediatricians (25.7%), who are currently active in professional associations in Texas.ResultsAbout three-fourths (74.0%) of participants reported that they would get the vaccine as soon as it became available. They estimated that slightly more than half (59.2%) of their patients would accept the vaccine, and 67.0% expected that the COVID-19 vaccine would be accepted in their local community. The majority of participants (87.8%) reported always, almost always or usually endorsing vaccines, including high levels of intention to recommend COVID-19 vaccination (81.5%). Participants felt most confident responding to patient concerns related to education about vaccine types, safety and necessity and reported least confidence in responding to personal or religious objections to COVID-19 vaccination.ConclusionsThe majority of the physicians surveyed stated that they would receive the COVID-19 vaccination when it was available to them and were confident in their ability to respond to patient concerns. With additional education, support and shifting COVID-19 vaccinations into primary care settings, primary care physicians can use the trust they have built with their patients to address vaccine hesitancy and potentially increase acceptance and uptake.

BackgroundOne limitation of the endovascular treatment of intracranial aneurysms is aneurysm recanalization. The Analysis of Recanalization after Endovascular Treatment of intracranial Aneurysm (ARETA) study is a prospective multicenter cohort study evaluating the factors associated with recanalization after endovascular treatment.MethodsThe current analysis is focused on patients treated by coiling or balloon-assisted coiling (BAC). Postoperative, mid-term vascular imaging, and evolution of aneurysm occlusion were independently evaluated by two neuroradiologists. A 3-grade scale was used for aneurysm occlusion (complete occlusion, neck remnant, and aneurysm remnant) and for occlusion evolution (improved, stable, and worsened). Recanalization was defined as any worsening of aneurysm occlusion.ResultsBetween December 2013 and May 2015, 16 French neurointerventional departments enrolled 1289 patients. A total of 945 aneurysms in 908 patients were treated with coiling or BAC. The overall rate of aneurysm recanalization at mid-term follow-up was 29.5% (95% CI 26.6% to 32.4%): 28.9% and 30.3% in the coiling and BAC groups, respectively. In multivariate analyses factors independently associated with recanalization were current smoking (36.6% in current smokers vs 24.5% in current non-smokers (OR 1.8 (95% CI 1.3 to 2.4); p=0.0001), ruptured status (31.9% in ruptured aneurysms vs 25.1% in unruptured (OR 1.5 (95% CI 1.1 to 2.1); p=0.006), aneurysm size ≥10 mm (48.8% vs 26.5% in aneurysms <10 mm (OR 2.6 (95% CI 1.8 to 3.9); p<0.0001), wide neck (32.1% vs 25.8% in narrow neck (OR 1.5 (95% CI 1.1 to 2.1); p=0.02), and MCA location (34.3% vs 28.3% in other locations (OR 1.5 (95% CI 1.0 to 2.1); p=0.04).ConclusionsSeveral factors are identified by the ARETA study as playing a role in aneurysm recanalization after coiling: current smoking, aneurysm status (ruptured), aneurysm size (≥10 mm), neck size (wide neck), and aneurysm location (middle cerebral artery). This finding has important consequences in clinical practice.Trial registration numberURL:http://www.clinicaltrials.gov; Unique Identifier:NCT01942512.

BackgroundHealthcare workers are at increased risk of infection due to occupational exposure to SARS-CoV-2-infected patients. The objective of this study was to determine the seroprevalence of SARS-CoV-2 in healthcare workers in Colombia.MethodsThis study is a cross-sectional study focused on estimating the seroprevalence of SARS-CoV-2 antibodies in healthcare workers from 65 hospitals in 10 cities in Colombia during the second semester of 2020. The seroprevalence was determined using an automated immunoassay (Abbott SARS-CoV-2 CLIA IgG). The study included a survey to establish the sociodemographic variables and the risk of infection. A multivariate model was used to evaluate the association between the results of seroprevalence and risk factors.ResultsThe global seroprevalence of antibodies against SARS-CoV-2 was 35% (95% Bayesian CI 33% to 37%). All the personnel reported the use of protective equipment. General services personnel and nurses presented the highest ratios of seroprevalence among the healthcare workers. Low socioeconomic strata have shown a strong association with seropositivity.ConclusionThis study estimates the prevalence of SARS-CoV-2 infection among healthcare workers. Even though all the personnel reported the use of protective equipment, the seroprevalence in the general services personnel and nurses was high. Also, a significant difference by cities was observed.
Measurement of inbreeding depression in Rhododendron kaempferi: seed production, germination, juvenile survival, and growth
Authors: Takahashi Keigo , Itino Takao 
Published: November 2021

To understand the reproductive ecology of a plant species with both selfing and outcrossing reproductive systems, it is important to know how selfed individuals contribute to the maintenance of a population. Further, examination of the magnitude of inbreeding depression after pollination is essential for the accurate measurement of reproductive success. In this study, we investigated the characteristics of viable seeds and seedlings of Rhododendron kaempferi Planch. in a region where the bumblebee pollinator Bombus ardens Smith, 1879 are abundant. In a hand-pollination experiment, the fruit set from self-pollination was 32%, significantly lower than that from outcross-pollination (81%). The number of seeds per fruit from self-pollination was one sixth the number from outcross-pollination. However, the number of seeds per fruit was negatively correlated with the mass per seed. In addition, the germination rate was low when the seed mass was light. Although selfed seeds could germinate, 89% of the seedlings died within a year. The inbreeding depression coefficient one year after sowing was very high (0.89). These results indicate that R. kaempferi shows extremely strong selection for outcrossing but maintains a slight selfing potential in a natural population in central Japan.

Aim. The study is aimed at developing curcumin suppositories as a promising approach for natural antifungal management of vaginal candidiasis in cervical cancer patients to eradicate side effects produced by current antifungal drugs. The objective of the study was to optimize the suppositories using optimal (custom) design employing Design-Expert 13 software to recognize the concentration of polyethylene glycols (PEG) and Poloxamer 407 and obtain a stable suppository. Methodology. Combinations of PEG 1500 (10%–40%), PEG 6000 (40%–60%), and Poloxamer 407 (5%–30%) were entered as factors, and the responses evaluated were hardness, deformation time, and % drug release. In addition, the formulation was also evaluated for visual examination, weight variation, pH determination, drug content, hardness test, disintegration time, melting zone, deformation time, in vitro drug release, antifungal activity, and stability tests. Results. Suppositories were devoid of holes and cracks, with a characteristic odor and a dark yellowish-orange color. All formulations passed the weight variation test.
