Tricuspid Annuloplasty: Transcatheter Approaches
Authors: Arnold Martin , Haug Julia , Landendinger Melanie 
Published: August 2021

AbstractPurpose of ReviewNew transcatheter techniques to perform tricuspid annuloplasty are evolving and are introduced into the clinical routine. Yet, clinical experience is limited.Recent FindingsCurrently, 3 different techniques for tricuspid annuloplasty have been used in larger clinical cohorts. They can be divided into direct annuloplasty techniques and suture plication techniques. The largest clinical evidence is related to direct annuloplasty techniques. It has been shown that annular dimensions can be effectively reduced. This translates into an improvement of the degree of tricuspid regurgitation and improvement of clinical symptoms. Due to the newness of this type of therapy, long-term data is limited, but for one of the described techniques, published data show that the positive effects persist over a 2-year period.SummaryTranscatheter approaches are safe and are able to treat tricuspid regurgitation effectively. There are still differences in the efficacy of the different techniques. Clinical experience varies among the different approaches.

Strategic clustering in right-wing-populism? ‘Green policies’ in Germany and France
Authors: Oswald Michael T. , Fromm Meike , Broda Elena 
Published: August 2021

AbstractPast research pointed to the idea that right-wing ideology and climate-change skepticism are inherently linked. Empirical reality proves differently however, since right-wing populist parties are starting to adapt pro environmentalist stances. In this paper, we look into two prominent cases of diametrical diverging environmental strategies by right-wing-populist-parties: France’s Rassemblement National and Germany’s Alternative für Deutschland. In order convey this point, we use comparative qualitative content analysis and examine several decisive determinants regarding environmental strategies of right-wing populist parties. We argue that right-wing-populism is remarkably adaptable considering political opportunity structures, even clustering in ideologically diametrical versions of the same issue while each party coherently extends its policy-orientation to its respective alignment of the issue. That means, populism might be far less ideological than assumed in the past.

Published: August 2021

AbstractIn empty well killing, in order to save the time and cost of killing the well, the dynamic replacement method is often used to kill the well. The main problem of the dynamic replacement method for killing wells is how to avoid terrible working conditions caused by flooding, such as gas carrying fluid, killing fluid being brought to the wellhead. Based on the principle of flooding formation and the basic tenets of flooding correlation experiment and dynamic replacement method, this paper incorporates the kill fluid viscosity, surface tension, droplet diameter, inclination angle, drill pipe joint outer diameter, and drill pipe eccentricity into the calculation range and establishes a new mathematical model suitable for dynamic replacement kill. Based on the calculation results, the influencing factors of flooding are analyzed, and the following conclusions are drawn: the increase of dynamic viscosity, gas density in the well, casing pressure, well angle, the outside diameter of drill pipe, the outer diameter of drill pipe joint, and eccentricity of drill pipe can promote the occurrence of flooding; The increase of surface tension, well-killing fluid density, and casing inner diameter have an obstacle to flooding.
A new group decision making approach based on incomplete probabilistic dual hesitant fuzzy preference relations
Authors: Song Juan , Ni Zhiwei , Jin Feifei , Li Ping , Wu Wenying 
Published: August 2021

AbstractAs an enhanced version of probabilistic hesitant fuzzy sets and dual hesitant fuzzy sets, probabilistic dual hesitant fuzzy sets (PDHFSs) combine probabilistic information with the membership degree and non-membership degree, which can describe decision making information more reasonably and comprehensively. Based on PDHFSs, this paper investigates the approach to group decision making (GDM) based on incomplete probabilistic dual hesitant fuzzy preference relations (PDHFPRs). First, the definitions of order consistency and multiplicative consistency of PDHFPRs are given. Then, for the problem that decision makers (DMs) cannot provide the reasonable associated probabilities of probabilistic dual hesitant fuzzy elements (PDHFEs), the calculation method of the associated probability is given by using an optimal programming model. Furthermore, the consistency level for PDHFPRs is tested according to the weighted consistency index defined by the risk attitude of DMs. In addition, a convergent iterative algorithm is proposed to enhance the unacceptable consistent PDHFPRs’ consistency level. Finally, a GDM approach with incomplete PDHFPRs is established to obtain the ranking of the alternatives. The availability and rationality of the proposed decision making approach are demonstrated by analyzing the impact factors of haze weather.
Extraction of Oleic Acid from Animals Oil and Its Anti-inflammatory Effect on Network Pharmacology

Published: August 2021

AbstractThe purpose of this paper is to explore the possible mechanisms of anti-inflammatory and scar repair by Mongolian horse oil. We used TCM database and literature mining to collect active compounds of horse oil and used Swiss TargetPrediction and SuperPred server to find targets of compounds. Anti-inflammatory drug targets were collected through the CTD database. Go annotation of targets and KEGG pathway were enriched and analyzed through Metascape database platform. Molecular docking between active ingredients and targets was verified by AutoDock software. Metascape analysis revealed that the key candidate targets were significantly enriched in a number of pathways associated with inflammatory pathology. The results of molecular docking showed that oleic acid, a major component of animals oil, could influence the regulatory functions of TNF, NGF, IL6, IL1B, Jun, and CDK1. This suggests that animals oil can regulate the development of inflammation through its active ingredient, oleic acid, and can influence the expression of multiple signaling pathways, with theoretical endogenous interactions with TNF, NGF, IL6, IL1B, JUN, and CDK1 proteins.
What do we read to our children? Messages concerning ethnic diversity in popular children’s books in the Netherlands
Authors: de Bruijn Ymke , Emmen Rosanneke A. G. , Mesman Judi 
Published: August 2021

AbstractChildren’s books can create opportunities for children to see themselves as well as others in different settings and stories, but cultural details and specificity within these stories can play an important role in the messages that children take away. Therefore, the present study aims to provide insight in the messages concerning ethnic diversity and various cultures in a subset of popular books that Dutch young children are likely to be exposed to. Books aimed at young children that were sold or borrowed most often or were awarded between 2009 and 2018 in the Netherlands are examined through the combined lens of critical race theory and critical multicultural analysis. Specifically, books including a protagonist or secondary character of color were selected. The study provides insight in the degree of cultural specificity and cultural authenticity, as well as prevailing power relations between characters and ideologies that are portrayed within the books. Results indicate that while cultural stereotypes and ideologies including White supremacy and eurocentrism are found only in a few books, cultural details are generally lacking and colorblindness is common in books aimed at young children. The study therefore underlines the particular need for books that are culturally specific and include authentic cultural details, to improve the reflection of various cultures and experiences of characters of color.
Plasma preheating technology for replicating planetary re-entry surface temperatures
Authors: Iyinomen D.O. 
Published: August 2021

AbstractArc-jet facilities have been the norm for ablation experiments used to calibrate computational models to date. However, the arc jet has a few major limitations and challenges, including non-uniform enthalpy distribution, non-equilibrium state, change of surface quality during testing and the extent of oxidation, to name but a few. A novel plasma technique for preheating axisymmetric heatshield samples in hypersonic impulse facilities is presented herein. The major aim of this innovative work is to help reduce the large variations of ablation rate predictions, space vehicle materials and missile design/testing, obtain strongly coupled hypersonic boundary layers and achieve lower cost of aerothermodynamics experiments. This present work remains one of the most highly anticipated solutions to maximise payload success and replicate high surface temperatures identical to those experienced by real flight vehicles. This work makes a useful contribution to re-entry studies under conditions that replicate the characteristics of re-entry flights. Future applications for the technique are expected to be found in hypersonic impulse facilities that can simulate the true flow energy under re-entry conditions.

Abstract
Clinical trials continue to face significant challenges in participant recruitment and retention. The Recruitment Innovation Center (RIC), part of the Trial Innovation Network (TIN), has been funded by the National Center for Advancing Translational Sciences of the National Institutes of Health to develop innovative strategies and technologies to enhance participant engagement in all stages of multicenter clinical trials. In collaboration with investigator teams and liaisons at Clinical and Translational Science Award institutions, the RIC is charged with the mission to design, field-test, and refine novel resources in the context of individual clinical trials. These innovations are disseminated via newsletters, publications, a virtual toolbox on the TIN website, and RIC-hosted collaboration webinars. The RIC has designed, implemented, and promised customized recruitment support for 173 studies across many diverse disease areas. This support has incorporated site feasibility assessments, community input sessions, recruitment materials recommendations, social media campaigns, and an array of study-specific suggestions. The RIC’s goal is to evaluate the efficacy of these resources and provide access to all investigating teams, so that more trials can be completed on time, within budget, with diverse participation, and with enough accrual to power statistical analyses and make substantive contributions to the advancement of healthcare.
The relative Bruce–Roberts number of a function on a hypersurface
Authors: Lima-Pereira B. K. , Nuño-Ballesteros J. J. , Oréfice-Okamoto B. , Tomazella J. N. 
Published: August 2021

AbstractWe consider the relative Bruce–Roberts number $\mu _{\textrm {BR}}^{-}(f,\,X)$ of a function on an isolated hypersurface singularity $(X,\,0)$. We show that $\mu _{\textrm {BR}}^{-}(f,\,X)$ is equal to the sum of the Milnor number of the fibre $\mu (f^{-1}(0)\cap X,\,0)$ plus the difference $\mu (X,\,0)-\tau (X,\,0)$ between the Milnor and the Tjurina numbers of $(X,\,0)$. As an application, we show that the usual Bruce–Roberts number $\mu _{\textrm {BR}}(f,\,X)$ is equal to $\mu (f)+\mu _{\textrm {BR}}^{-}(f,\,X)$. We also deduce that the relative logarithmic characteristic variety $LC(X)^{-}$, obtained from the logarithmic characteristic variety $LC(X)$ by eliminating the component corresponding to the complement of $X$ in the ambient space, is Cohen–Macaulay.
Risk factors and health status among older adults in Europe: a socioeconomic analysis
Authors: Tur-Sinai Aviad , Becker Nir 
Published: August 2021

AbstractThe risk of developing a major non-communicable disease is critically affected by lifestyle choices. This study examined the consequences of factors that might predict a change in the self-rated health of older adults and aimed to assess their monetary costs. In particular, two predisposing risk factor moderators were studied: high blood pressure and high cholesterol. The effects of these on two serious adverse cardiovascular events – heart attack and stroke – were estimated. Using data from the Survey of Health, Aging and Retirement in Europe (SHARE) carried out in 2014, a two-stage procedure was applied as well as pairwise comparison. The results revealed the significant role of socioeconomic status in health outcomes. Behavioural risk factors were found to be significant predictors for heart attack and stroke. The findings support the claim that variables such as age, wealth and behavioural risk factors are additional predictors of a change in these two diseases. The monetary consequences can reach up to 12.8 thousand Euros for older adults per unit of predisposing risk factor. Since national health budgets are limited, health policies might be prioritized.
Morphological and molecular assessment of the diversity of trematode communities in freshwater gastropods and bivalves in Los Tuxtlas tropical rainforest
Authors: Velázquez-Urrieta Y. , Pérez-Ponce de León G. 
Published: August 2021

Abstract
Trematode life cycles involve molluscs as first intermediate hosts. The identification of trematodes based on the morphology of cercariae released from molluscs is challenging because the identification relies on adult forms obtained from their definitive hosts. Several studies have recently genetically characterized these larval forms establishing a link with adults sampled from their vertebrate hosts, allowing their identification at species level. In Los Tuxtlas tropical rainforest, in south-eastern Mexico, 57 species of trematodes have been reported from wildlife vertebrates; however, studies evaluating the diversity of trematode cercariae in molluscs are lacking. Here, we studied 11 species of molluscs to assess the diversity of cercariae in two lakes of Los Tuxtlas, Veracruz, Mexico; six of the 11 species were infected. Twelve cercarial morphotypes were collected and characterized morphologically. Sequences of the 28S ribosomal RNA gene were generated to allocate each morphotype into a family using the most recent phylogenetic classification of the Digenea as a framework; molecular work revealed 16 genetic lineages; some cercariae were identified up to genus (Apharyngostrigea, Ascocotyle, Centrocestus, Echinochasmus, Lecithodendrium and Posthodiplostomum), and some to species levels (Gorgoderina rosamondae, Langeronia macrocirra, Oligogonotylus manteri and Phyllodistomum inecoli) based on their phylogenetic position within the tree, and the genetic distance with respect to other sequenced congeners. Therefore, the cercarial morphotypes in the present study represent at least 16 putative species. Our study contributes to a better understanding of the trematode diversity in an area of high vertebrate species diversity, and to the knowledge of trematode life cycles.
Morphological description of Arctic sea anemone Haliactis arctica Carlgren, 1921 and taxonomic status of Halcampactinidae Carlgren, 1921 and Haliactinidae Carlgren, 1921
Authors: Ivanova Natalia Yu. 
Published: August 2021

AbstractHaliactis arctica is a poorly known species of sea anemone of the family Halcampactinidae known only from the Arctic. So far, there have been no reports of it after the original description, based on a few specimens from Greenland, Spitsbergen, the Barents Sea, Novaya Zemlya and the Chukchi Sea. The rich collection of the Zoological Institute RAS, which includes more than 100 specimens, has allowed a detailed morpho-anatomical study of this sea anemone. Examination of the external and internal morphology of H. arctica indicates a noticeable variability of structural features, especially the retractor muscles, parietal muscles and acontia. Comparison of characters between H. arctica with the other representatives of Halcampactinidae shows significant differences in the organization of these anemones. Their morphological differences and also significant geographic remoteness suggest that they should be attributed to different families, however, at present it is impossible to conduct thorough molecular genetic studies that can confirm or refute this assumption.
Variation sets in the speech directed to toddlers in Argentinian households.SES and type of activity effects
Authors: ALAM Florencia , ROSEMBERG Celia Renata , GARBER Leandro , STEIN Alejandra 
Published: August 2021

AbstractThe study adopts a naturalistic perspective, looking at the relationship between socio-economic status (SES), activities and variation sets in child-directed speech (CDS) to Spanish-speaking Argentinian toddlers. It aims to determine the effect of SES and type of activity on the proportion of words and utterances in variation sets and on the pragmatic function they serve in interaction. Thirty two children (mean: 14.3 months) and their families were audio-recorded for four hours and the middle two hours were analyzed using CLAN. We developed an automatic algorithm for variation sets extraction that compares noun, verb and adjective lexemes in successive utterances. Mixed-effects beta regression showed SES and activity type effects on the proportion of variation sets and on the pragmatic function served by variation sets. Findings revealed that the contextual variables considered impact on how interlocutors organize the information to young children at the local level of natural at home interactions.
The making and UN-making of consensus: Institutional inertia in the UNESCO World Heritage Committee
Authors: Liuzza Claudia 
Published: August 2021

AbstractThis article examines the process of text-based negotiations surrounding the documents of the 1972 Convention Concerning the Protection of the World Cultural and Natural Heritage. It focuses on revisions to the Operational Guidelines of the Convention and utilizes ethnographic observation and textual examination to show how alternative, and often the most controversial, proposals are silenced through the practice of consensus. It expands anthropological perspectives on the inner workings of intergovernmental institutions and adds to the literature on heritage regimes by providing examples from United Nations Educational, Scientific and Cultural Organization’s (UNESCO) most prestigious intergovernmental committee. Ultimately, the article enhances our understanding of the political tensions and practical limitations of policymaking within intergovernmental organizations in the United Nations, including UNESCO.
LOCALIZED RADIAL BASIS FUNCTIONS FOR NO-ARBITRAGE PRICING OF OPTIONS UNDER STOCHASTIC ALPHA–BETA–RHO DYNAMICS
Authors: THAKOOR N. 
Published: August 2021

AbstractClosed-form explicit formulas for implied Black–Scholes volatilities provide a rapid evaluation method for European options under the popular stochastic alpha–beta–rho (SABR) model. However, it is well known that computed prices using the implied volatilities are only accurate for short-term maturities, but, for longer maturities, a more accurate method is required. This work addresses this accuracy problem for long-term maturities by numerically solving the no-arbitrage partial differential equation with an absorbing boundary condition at zero. Localized radial basis functions in a finite-difference mode are employed for the development of a computational method for solving the resulting two-dimensional pricing equation. The proposed method can use either multiquadrics or inverse multiquadrics, which are shown to have comparable performances. Numerical results illustrate the accuracy of the proposed method and, more importantly, that the computed risk-neutral probability densities are nonnegative. These two key properties indicate that the method of solution using localized meshless methods is a viable and efficient means for price computations under SABR dynamics.

Published: August 2021

AbstractWe study finite maturity American-style stock loans under a two-state regime-switching economy. We present a thorough semi-analytic discussion of the optimal redeeming prices, the values and the fair service fees of the stock loans, under the assumption that the volatility of the underlying is in a state of uncertainty. Numerical experiments are carried out to show the effects of the volatility regimes and other loan parameters.
Strategies to terminate summer cover crops for weed management in no-tillage vegetable production in southeast Brazil
Authors: Branco Roberto Botelho Ferraz , Carvalho Fernando de , Oliveira João Paulo , Alves Pedro Luis da Costa 
Published: August 2021

AbstractCover crop residue left on the soil surface as organic mulch in no-tillage crop production provides several environmental benefits, including weed suppression. Thus, many farmers who use cover crops attempt to reduce the use of agricultural inputs, especially herbicides. Therefore, our objectives were to study the potential of different cover crop species to suppress weeds and produce an in situ organic mulch and to evaluate the effect of the organic mulch with and without spraying glyphosate on weed suppression for vegetable (tomato [Solanum lycopersicumL.] and broccoli [Brassica oleraceaL. var.botrytis]) growth and yield. Five cover crop treatments (sunn hemp [Crotalaria junceaL.], jack bean [Canavalia ensiformis(L.) DC.], pearl millet [Pennisetum glaucum(L.) R. Br.], forage sorghum [Sorghum bicolor(L.) Moench ssp.bicolor], and no cover crop [control]) were used in the main plots; and glyphosate was or was not sprayed on the flattened cover crop in the subplots of this split-plot experimental design. Organic mulch from pearl millet, sorghum, and sunn hemp resulted in lower weed biomass during the early seasons of both tomato and broccoli than mulch from jack bean and no cover crop (control). Spraying glyphosate after roller-crimping reduced weed biomass by 103 g m−2and 20 g m−2by 45 and 60 d after transplanting (DATr) of tomato, respectively, and resulted in a better tomato yield compared with not spraying. Glyphosate reduced weed biomass by 110 g m−2in the early season of broccoli (30 DATr) but did not affect yield. Terminating high-biomass cover crops with a roller-crimper is a promising technique for weed management in vegetable crops that has the potential to reduce or even eliminate the need for herbicide.
