Published: June 2022

AbstractA global survey of researchers was conducted to gather perceptions on the prevalence and impact of predatory academic journals and conferences. The survey was open and inclusive in nature, with 1872 researchers, from a wide array of geographic regions, disciplines and academic career stages, voluntarily participating. Both quantitative and qualitative data were collected and analysed. The survey revealed that over 80% (1537 of 1859) of respondents perceive predatory practices are already a serious problem or on the rise in their country of work, and risk infiltrating and undermining the research enterprise if left unchallenged. At least 24% (445 of 1872) of respondents admitted they had already published in a predatory journal, participated in a predatory conference, or did not know if they had. Over 87% of respondents who had published (174 of 199) or participated (60 of 64) indicated that a lack of awareness of predatory practices was the main reason. Those in lower‐middle and upper‐middle‐income countries were more likely to indicate they had engaged in these activities than those in high‐income ones, with some disciplines appearing to engage more than others. Individual impact was mixed: some indicated no impact while others noted a range of negative and detrimental feelings.

AbstractObjectiveInvasive fungal sinusitis (IFS) in patients with active or recent COVID‐19 have been reported throughout the world. The primary purpose of the systematic review is to describe factors associated with IFS in patients with COVID‐19. The goal of the case series was to also characterize these factors in addition to evaluating the incidence of IFS at our institution after the onset of the pandemic.MethodsA systematic review using the preferred reporting in systematic reviews and meta‐analyses (PRISMA) framework identified publications of IFS cases associated with COVID‐19 (IFSAC). Search terms were “COVID‐19,” “invasive,” “fungal,” and “sinusitis.” IFS cases were evaluated for COVID‐19 status, fungal etiology, comorbidities, treatment, and outcome. A case series of patients at our center with IFS between December 1, 2018 to March 31, 2020 (“pre‐covid”) and April 1, 2020 to August 1, 2021 (“post‐covid”) was also performed with the above parameters.ResultsFourteen studies totaling 206 cases of IFSAC were identified. Most cases came from India (140/206, 68.0%), followed by Egypt (62/206, 30.1%), and North America (4/206, 1.9%). Diabetes was the most common comorbidity (151/206, 73.3%). Recent or prolonged steroid use was noted in 65.0% of cases (134/206). In our series, five pre‐covid and four post‐covid cases were identified. One had recent COVID‐19 infection. Acute myeloid leukemia was the most common pre‐covid comorbidity (3/5, 60.0%). Diabetes was the most frequent post‐covid comorbidity (2/4, 50.0%). Chronic steroid usage was noted in two pre‐covid and one post‐covid cases.ConclusionDiabetes and steroid use are common factors in reported cases of IFSAC. IFS incidence in our case series did not change appreciably after the onset of the pandemic.Level of Evidence: 4.
Functional genomics of reproduction in pigs: Are we there yet?
Authors: Nonneman Dan J. , Lents Clay A. 
Published: June 2022

AbstractReproductive failure is the main reason for culling females in swine herds and is both a financial and sustainability issue. Because reproductive traits are complex and lowly to moderately heritable, genomic selection within populations can achieve substantial genetic gain in reproductive efficiency. A better understanding of the physiological components affecting the expression of these traits will facilitate greater understanding of the genes affecting reproductive traits and is necessary to improve and optimize management strategies to maximize reproductive success of gilts and sows. Large‐scale genotyping with single‐nucleotide polymorphism (SNP) arrays are used for genome‐wide association studies (GWAS) and have facilitated identification of positional candidate genes. Transcriptomic data can be used to weight SNP for GWAS and could lead to previously unidentified candidate genes. Resequencing and fine mapping of candidate genes are necessary to identify putative functional variants and some of these have been incorporated into new genotyping arrays. Sequence imputation and genotype by sequence are newer strategies that could reveal novel functional mutations. In this study, these approaches are discussed. Advantages and limitations are highlighted where additional research is needed.

Published: June 2022

AbstractCarbon‐phenolic ablators are very efficient heat shields for atmospheric reentry vehicles: they are able to protect a capsule from hyper thermal environments characterized by intense heat fluxes (>1 MW/m2) and very high temperature (also exceeding 300°C). Ablative materials can be modified by the addition of nano‐fillers in order to improve their performance: small amounts of nano‐fillers (in the order of 2–5 wt%) are able to enhance the matrix material properties, guarantying a weight saving too. In this work, three different kinds of ceramic nano‐particles (ZrO2, SiC, and MgO) were tested as fillers for a phenolic resin and for a carbon‐phenolic ablator: the variation in the mechanical properties and ablative performances were verified through mechanical tests and oxyacetylene flame exposure. The influence of the nano‐particles in the composite materials properties and the phenomena connected to their presence in the ablative material were deeply investigated with scanning electron microscope, EDS, XRD, and FTIR analysis.

AbstractThe forced changes and disruptions in educational systems and learning experiences due to the pandemic has impacted students' mental health and well‐being. The present study aims to understand the effects of the determinants of well‐being on students in India during the second wave (April to August 2021) of the COVID‐19 pandemic. The determinants of well‐being in this study are academic grit, intolerance to uncertainty and students' engagement in an online learning environment. In this study, well‐being is characterized as students' confidence and satisfaction in an online learning and pandemic environment. The data collected from 1174 students (12–19 years) from various states, using standardized tools, were analyzed to find out about the mediating effect of students' engagement on the relationship between academic grit and well‐being, and between intolerance to uncertainty and well‐being. Further, the model fit analysis of the determinants of well‐being is explored. The paper reports that students' classroom engagement does mediate in the path of academic grit and well‐being, and in the path of intolerance to uncertainty and well‐being. It also evidence the model fit of the influence of the determinants of well‐being on that of school students during the second wave of the COVID‐19 pandemic. The study also draws implications and suggestions for educators using the current model of students' well‐being.
Poly(hydroxyurethane‐co‐thiourethane)s cross‐linked with disulfide bonds: Synthesis via isocyanate‐free approach, thermomechanical and reprocessing properties

AbstractBoth difunctional five‐membered cyclic carbonate (E5CC) and trithiocarbonate (E5CTC) were synthesized via the reactions of diglycidyl ether of bisphenol A (DGEBA) with carbon dioxide (CO2) and carbon disulfide (CS2), respectively. These two monomers were employed to synthesize linear poly(hydroxyurethane‐co‐mecaptotrithiourethane) [P(HU‐co‐MTU)] copolymers via the polymerization with an α,ω‐diamino‐terminated poly(propylene oxide). By controlling the mole ratios of E5CC to E5CTC, the P(HU‐co‐MTU) copolymers were synthesized with variable contents of thiol groups. It was found that the linear P(HU‐co‐MTU) copolymers were readily cross‐linked with the disulfide bonds which were in situ generated via the radical coupling of the side thiol groups. The cross‐linking exerted a profound impact on the thermomechanical properties of the materials. The glass transition temperature (Tg's), Young's moduli and tensile strengths were significantly enhanced with increasing the contents of disulfide bonds. More importantly, the networks significantly displayed the self‐healing and reprocessing properties, which are attributable to the dynamic exchanges of disulfide bonds.

AbstractIn seropositive rheumatoid arthritis (RA), the onset of clinically apparent inflammatory arthritis (IA) is typically preceded by a prolonged period of autoimmunity manifest by the presence of circulating autoantibodies that can include antibodies to citrullinated protein antigens (ACPA) and rheumatoid factor. This period before clinical IA can be designated preclinical RA in those individuals who have progressed to a clinical diagnosis of RA, and an “at‐risk” status in those who have not developed IA but exhibit predictive biomarkers of future clinical RA. With the goal of developing RA prevention strategies, studies have characterized immune phenotypes of preclinical RA/at‐risk states. From these studies, a model has emerged wherein mucosal inflammation and dysbiosis may lead first to local autoantibody production, which should normally be transient, but instead is followed by a systemic spread of the autoimmunity as manifested by serum autoantibody elevations, ultimately driving the development of clinically identified joint inflammation. This model can be envisioned as the progression of disease development through serial “checkpoints” that in principle should constrain or resolve autoimmunity; however, instead, the checkpoints “fail” and clinical RA develops. Herein we review the immune processes that are likely to be present at each step and the potential therapeutic strategies that could be envisioned to delay, diminish, halt, or even reverse the progression to clinical RA. Notably, these prevention strategies could utilize existing therapies approved for clinical RA, therapies approved for other diseases that target relevant pathways in the preclinical/at‐risk state, or approaches that target novel pathways.
Influence of invasive crayfish on fine sediment transport, ingress and bed storage in lowland rivers

Published: June 2022

AbstractHistorically it has been assumed that abiotic forces dominate fluvial sediment dynamics. However, a growing body of work indicates that biological energy can also exert a significant control over sediment dynamics. The role that invasive species may play in altering fine sediment dynamics is particularly pertinent given that any influence may disrupt the natural equilibrium of the ecosystem. Here we investigated the effect of invasive signal crayfish (Pacisfastcus leniusculus) on the transport and storage of fine sediment in a densely populated river compared with a nearby control river without crayfish, over an 18‐week period. We observed clear evidence of diurnal fluctuations in turbidity associated with crayfish presence including periodograms with power peaks at a period of 1 day. Fine sediment fluxes indicated that crayfish contributed on average 18.5% extra to baseflow loads than would be likely under abiotic forcing alone. Temporal variations in suspended sediment concentrations were also observed at the control site but these were different in character and exhibited no clear temporal pattern or consistency as confirmed by periodogram analysis. Crayfish did not have an effect on sediment ingress rates relative to the control site and, at the crayfish site, the reach scale sediment budget was in net equilibrium during the sampling period. Our results provide further evidence that biological energy alters riverine fine sediment dynamics and warrants consideration in sediment dynamic models.

Published: June 2022

AbstractTransition metal dichalcogenides (TMDCs)‐based laminar membranes have gained significant interest in energy storage, fuel cell, gas separation, wastewater treatment, and desalination applications due to single layer structure, good functionality, high mechanical strength, and chemical resistivity. Herein, we review the recent efforts and development on TMDCs‐based laminar membranes, and focus is given on their fabrication strategies. Further, TMDCs‐based laminar membranes for water purification and seawater desalination are discussed in detail. Finally, present their merits, limits and future challenges needed in this area.
Settling Down and Setting Up: Itinerant Peddlers from Russian Karelia as Shopkeepers in Late Nineteenth- and Early Twentieth-Century Finland
Authors: Sundelin Anna 
Published: June 2022

AbstractThe chapter analyzes mobile traders from Russian Karelia who abandoned their itinerant livelihood and settled down in Finland in the late nineteenth and early twentieth century. Many of these former peddlers opened up stores in the Finnish countryside, making use of their skills as traders and previously formed networks to keep their stores well supplied. The analysis revolves around the relationship between local residents and strangers settling down. By combining ethnographical sources with newspaper writings and advertisements the chapter offers new insights into the transition from itinerant peddling to storekeeping as well as the experiences of migrant entrepreneurs in Finland at the turn of the twentieth century.

Published: June 2022

AbstractIn this paper, we convey the results of our digital fieldwork within the current mediascape (English) by examining online reactions to an important source of cultural influence: the news media's depiction of older adult's stress, the proposals offered to older adults to assist them in coping with the stress of living in the COVID-19 pandemic, and finally, the responses of online commentators to these proposals. A quasi-automated social network analysis of 3390 valid comments in seven major international news outlets (Jan-June 2020), revealed how older adults were generally resourceful and able to cope with COVID-19 stress. For many in this technology-using sample, information and communication technologies (ICTs) were important for staying informed, busy, and connected, but they were not the primary resources for coping. Although teleconferencing tools were praised for facilitating new forms of intergenerational connection during the lockdowns, they were considered temporary and inadequate substitutes for connection to family. Importantly, older adults objected to uncritical and patronizing assumptions about their ability to deal with stress, and to the promotion of ICTs as the most important coping strategy. Our findings underline the necessity of a critical and media-ecological approach to studying the affordances of new ICTs for older adults, which considers changing needs and contextual preferences of aging populations in adoption of de-stressing technologies.

Published: June 2022

Abstract
Future experiments dedicated to the detection of Coherent Elastic Neutrino-Nucleus Scattering may be powerful tools in probing light new physics. In this paper we study the sensitivity on light Z′ mediators of two proposed experiments: a directional low pressure Time Projection Chamber detector, νBDX-DRIFT, that will utilize neutrinos produced at the Long Baseline Neutrino Facility, and several possible experiments to be installed at the European Spallation Source. We compare the results obtained with existing limits from fixed-target, accelerator, solar neutrino and reactor experiments. Furthermore, we show that these experiments have the potential to test unexplored regions that, in some case, could explain the anomalous magnetic moment of the muon or peculiar spectral features in the cosmic neutrino spectrum observed by IceCube.

Published: June 2022

Abstract
We study probe scalar correlation functions in a Solodukhin wormhole corresponding to the non-rotating BTZ black hole, as a toy model for microstate geometries thereof. Using real-time holography, we obtain the retarded scalar correlator in the wormhole geometry and quantitatively compare it to the result of the hybrid WKB method for the same correlator. We also calculate an off-diagonal correlator ∼ 〈HLLH′〉 involving two different (heavy) wormhole states.
The see-saw portal at future Higgs factories: the role of dimension six operators
Authors: Barducci Daniele , Bertuzzo Enrico 
Published: June 2022

Abstract
We study an extension of the Standard Model with electroweak scale right-handed singlet fermions N that induces neutrino masses, plus a generic new physics sector at a higher scale Λ. The latter is parametrized in terms of effective operators in the language of the νSMEFT. We study its phenomenology considering operators up to d = 6, where additional production and decay modes for N are present in addition to those arising from the mixing with the active neutrinos. We focus on the production with four-Fermi operators and we identify the most relevant additional decay modes to be N → νγ and N → 3f. We assess the sensitivity of future Higgs factories on the νSMEFT in regions of the parameter space where the new states decay promptly, displaced or are stable on detector lengths. We show that new physics scale up to 5–60 TeV can be explored, depending on the collider considered.
Penalized maximum likelihood estimator for mixture of von Mises–Fisher distributions
Authors: Ng Tin Lok James 
Published: June 2022

AbstractThe von Mises–Fisher distribution is one of the most widely used probability distributions to describe directional data. Finite mixtures of von Mises–Fisher distributions have found numerous applications. However, the likelihood function for the finite mixture of von Mises–Fisher distributions is unbounded and consequently the maximum likelihood estimation is not well defined. To address the problem of likelihood degeneracy, we consider a penalized maximum likelihood approach whereby a penalty function is incorporated. We prove strong consistency of the resulting estimator. An Expectation–Maximization algorithm for the penalized likelihood function is developed and experiments are performed to examine its performance.

Published: June 2022

AbstractBackgroundPrimary hyperparathyroidism (pHPT) is well treatable surgically. Sonography (US) and sestamibi scintigraphy (MIBI) are used routinely, but it is unclear how valuable they are in determining Parathyroid glands’ different locations. This study aimed to evaluate the prognostic value of US and MIBI in relation to the different localization of parathyroid adenomas in one of the largest study populations analyzed to date.Methods1089 patients with pHPT who had treatment in one tertiary referral center between 2007 and 2016 were analyzed. Preoperative US and MIBI reports were compared with the parathyroid adenoma's intraoperative localization. All parathyroid glands were confirmed by histological diagnosis.ResultsNo gland was detectable in 22.5% and 27.7% of all patients, by US or by MIBI, respectively. In relation to the different adenoma locations, the sensitivity of US ranged from 21.3% (upper right) to 68.9% (lower left) and of MIBI ranged from 23.5% (upper right) to 72% (lower left). The specificity for US ranged from 85% (lower right) to 99.2% (upper right) and for MIBI ranged from 86.1% (lower right) to 99.1% (upper right. Positive predictive values for all gland sites were 54% and 59% for MIBI and US, respectively. The value increased for side‐only prediction to 73% and 78%, respectively. Neither the parathyroid hormone level nor the calcium value level influenced the sensitivity or specificity of the two test methods.ConclusionsThe validity of preoperative US and MIBI depends crucially on the specific localization of adenomas. This should be considered when planning the extent of parathyroid surgery.
