How Liquid Marbles Break Down: Direct Evidence for Two Breakage Scenarios
Authors: Tenjimbayashi Mizuki , Fujii Syuji 
Published: August 2021

AbstractLiquid marbles are nonsticking droplets wrapped with hydrophobic nano‐ to micrometer particles and are expected to be useful for various applications, especially in industrial and biomedical fields. However, the practical use of liquid marbles is limited by their fragility. In this study, the dynamics of particle monolayer–stabilized liquid marble breakage upon impacting a solid surface are monitored in situ by high‐speed interfacial microscopy. The experiments show that the breakage of liquid marbles can be induced by either i) cracking or ii) water penetration depending on the impact energy. The applicable scenario is determined by whether a jamming transition of the wrapping particles occurs during impact. The breakage mechanisms provide insights on how to improve the robustness of liquid marbles in accordance with these scenarios.

Published: August 2021

AbstractThis article describes the professional identity formation of a group of pre‐service English as a foreign language student‐teachers at an initial English language teacher education program in Argentina. To this effect, a four‐year longitudinal study was designed drawing on the concept of funds of identity. Participants’ drawing of significant circles and interviews were used to document the main components of their funds of professional identity and the factors which informed their construction. In this paper, we specifically describe three student‐teachers’ funds of professional identity to exemplify three trends identified across the participants: (1) knowledge as a constant fund, (2) a shift from past to present and future funds, and (3) a shift from external to internal funds. Drawing on Esteban‐Guitart’s (2014) typology of funds of identity, this study puts forward a typology of funds of professional identity which incorporates three new funds, valuative, disciplinary, and anticipatory, to understand student‐teachers’ trajectories in language teacher education.

Published: August 2021

AbstractA mathematical model is presented to explore the SH‐wave (horizontally polarized shear wave) propagation in a temperature‐dependent viscoelastic medium laid on a vertically heterogeneous elastic half‐space. Heterogeneity in the half‐space arises due to nth order depth variation in the elastic constants. Bessel's and Whittaker's functions have been used to derive the internal deformations. The expression of the complex frequency equation has been obtained with the aid of suitable boundary conditions. The decomposition of the complex frequency equation into real and imaginary parts provides dispersion and damping equations. These equations exhibited their reliance on the temperature ratio parameter, attenuation coefficient and dissipation factor due to viscoelasticity, heterogeneity and order of heterogeneity function. The impacts of the aforesaid parameters on the propagation of SH‐wave have been studied numerically and demonstrated by 2D/3D graphs.
Surrogate model–based inverse parameter estimation in deep drawing using automatic knowledge acquisition
Authors: Ryser Matthias , Neuhauser Felix M. , Hein Christoph , Hora Pavel , Bambach Markus 
Published: August 2021

AbstractIn this paper, we propose a new approach for the simulation-based support of tryout operations in deep drawing which can be schematically classified as automatic knowledge acquisition. The central idea is to identify information maximising sensor positions for draw-in as well as local blank holder force sensors by solving the column subset selection problem with respect to the sensor sensitivities. Inverse surrogate models are then trained using the selected sensor signals as predictors and the material and process parameters as targets. The final models are able to observe the drawing process by estimating current material and process parameters, which can then be compared to the target values to identify process corrections. The methodology is examined on an Audi A8L side panel frame using a set of 635 simulations, where 20 out of 21 material and process parameters can be estimated with an R2 value greater than 0.9. The result shows that the observational models are not only capable of estimating all but one process parameters with high accuracy, but also allow the determination of material parameters at the same time. Since no assumptions are made about the type of process, sensors, material or process parameters, the methodology proposed can also be applied to other manufacturing processes and use cases.
Identifying communicative functions in discourse with content types
Authors: Caselli Tommaso , Sprugnoli Rachele , Moretti Giovanni 
Published: August 2021

AbstractTexts are not monolithic entities but rather coherent collections of micro illocutionary acts which help to convey a unitary message of content and purpose. Identifying such text segments is challenging because they require a fine-grained level of analysis even within a single sentence. At the same time, accessing them facilitates the analysis of the communicative functions of a text as well as the identification of relevant information. We propose an empirical framework for modelling micro illocutionary acts at clause level, that we call content types, grounded on linguistic theories of text types, in particular on the framework proposed by Werlich in 1976. We make available a newly annotated corpus of 279 documents (for a total of more than 180,000 tokens) belonging to different genres and temporal periods, based on a dedicated annotation scheme. We obtain an average Cohen’s kappa of 0.89 at token level. We achieve an average F1 score of 74.99% on the automatic classification of content types using a bi-LSTM model. Similar results are obtained on contemporary and historical documents, while performances on genres are more varied. This work promotes a discourse-oriented approach to information extraction and cross-fertilisation across disciplines through a computationally-aided linguistic analysis.

Published: August 2021

AbstractThe relationship between anxiety and mathematics has often been investigated in the literature. Different forms of anxiety have been evaluated, with math anxiety (MA) and test anxiety (TA) consistently being associated with various aspects of mathematics. In this meta-analysis, we have evaluated the impact of these forms of anxiety, distinguishing between different types of mathematical tasks. In investigating this relationship, we have also included potential moderators, such as age, gender, working memory, type of task, and type of material. One hundred seventy-seven studies met the inclusion criteria, providing an overall sample of 906,311 participants. Results showed that both MA and TA had a significant impact on mathematics. Sociodemographic factors had modest moderating effects. Working memory (WM) also mediated the relationship between MA and TA with mathematics; however, this indirect effect was weak. Theoretical and educational implications, as well as future directions for research in this field, are discussed.
Impact of implementation of the Dependency Act on the Spanish economy: an analysis after the 2008 financial crisis

Published: August 2021

AbstractThe aim of this paper is to assess the industry-wide impact of Long-Term Care (LTC) spending on the Spanish economy. LTC spending includes beneficiaries’ copayment and the impact is quantified in terms of output, employment and value added. To this purpose, we use an input–output model of the Spanish economy that allows us to further describe how the value added generated is distributed throughout the economy according to the existing benefit-mix (in kind services, cash benefit for informal care and cash benefit for personal assistance). Additionally, the model provides results on how the return on LTC spending would improve by using only in-kind services instead of the benefit mix currently in place. The 2012 Spanish Input–Output Table at current prices was extracted from the WIOD Database’s 2016 Release. Consumption data for dependent, employed, and unemployed households were collected from the Spanish Household Budget Survey for 2012. The findings reveal that the total annual costs are 7,205.43 million €, with total costs from in-kind services being almost 71% higher than total costs from cash benefits. Each million euros invested in in-kind services and CBPA would create 41.91 jobs (68.41% direct, 9.16% indirect and 22.43% induced). However, each million euros spent on cash benefits would result in 16.88 jobs overall (53.02% direct, 24.53% indirect and 22.45% induced). The total number of jobs is 151,353 at the aggregate level, being 46,840 depending on cash-benefits and 104,513 on in-kind services.

Contextualizing Ancestral Pueblo Turkey (Meleagris gallopavo spp.) Management
Authors: Conrad Cyler 
Published: August 2021

AbstractPenning turkeys (Meleagris gallopavospp.) in the Ancestral Pueblo American Southwest/Mexican Northwest (SW/NW) involved the creation or use of a variety of spaces and contexts throughout AD 1–1600 and into the post-contact era. Turkey pens, or captivity, occur through simple tethering, reuse of abandoned pit houses or surface rooms, or creation of pens within villages, plazas, and elsewhere. Turkey dung, droppings, and eggshells are fundamental for determining the presence or absence of pens at archaeological sites. In this paper, I review the archaeological record for turkey pens and focus on three main questions: (1) how are turkey pens identified in the SW/NW, (2) if turkey pen construction or evidence for turkey captivity shifts through time, and (3) what the record of turkey penning informs us regarding the long-term human management of these birds and global perspectives on human–bird/human–animal management. Ancestral Pueblo peoples created an adaptive and flexible strategy for turkey penning, which successfully integrated these birds into ceremonial and socioeconomic processes for approximately 1600 years.
Halloysite silanization in polyethylene terephthalate composites for bottling and packaging applications
Authors: Garcia-Escobar Fernando , Bonilla-Rios Jaime , Espinoza-Martinez Adriana Berenice , Cerda-Hurtado Patricia 
Published: August 2021

AbstractComposite materials of polyethylene terephthalate with silanized halloysite nanoclay were prepared and characterized. Halloysite was first functionalized with benzoyloxypropyltrimethoxysilane and then incorporated it into the polymer matrix via melt extrusion at 0.5, 1, and 2 wt% clay load ratios. The modified clay was characterized by means of elemental carbon quantification, thermogravimetric analysis, X-ray diffraction, and nitrogen adsorption–desorption. The silanization was confirmed to have taken place with an approximate reaction yield of 5%. While the silanization did not significantly affect the crystal structure or the morphological properties of the clay, a mass loss starting from 190 °C attributed to the organosilane compound used to modify the clay was observed in the reacted samples, along with increased thermal stability. The composite materials exhibited an increase in Young’s modulus and a decrease in the ultimate strain, but not a significant change in the oxygen permeability of the composites with respect to the neat PET.

Neighbourhood deprivation and the Big Five personality traits: associations with adolescent problem behaviour and educational attainment
Authors: Nieuwenhuis Jaap , Kleinepier Tom , Janssen Heleen , van Ham Maarten 
Published: August 2021

AbstractWe studied the relation between cumulative exposure to neighbourhood deprivation and adolescents’ Big Five personality traits, and the moderating role of personality in the relation between neighbourhood deprivation and the development of problem behaviour and educational attainment. We studied 5365 British adolescents from ages 10 to 16, with neighbourhood information from birth onwards. Extraversion, agreeableness, emotional stability, and openness to experience moderated the relation between deprivation and problem behaviour. For educational attainment, only extraversion was a moderator. This means that higher values on personality traits were related to weaker relations between neighbourhood deprivation and problem behaviour and educational attainment. The results showed the importance of taking into account adolescents’ personality when assessing developmental outcomes in relation to neighbourhood deprivation.
Intrinsically disordered proteins identified in the aggregate proteome serve as biomarkers of neurodegeneration

Published: August 2021

AbstractA protein’s structure is determined by its amino acid sequence and post-translational modifications, and provides the basis for its physiological functions. Across all organisms, roughly a third of the proteome comprises proteins that contain highly unstructured or intrinsically disordered regions. Proteins comprising or containing extensive unstructured regions are referred to as intrinsically disordered proteins (IDPs). IDPs are believed to participate in complex physiological processes through refolding of IDP regions, dependent on their binding to a diverse array of potential protein partners. They thus play critical roles in the assembly and function of protein complexes. Recent advances in experimental and computational analyses predicted multiple interacting partners for the disordered regions of proteins, implying critical roles in signal transduction and regulation of biological processes. Numerous disordered proteins are sequestered into aggregates in neurodegenerative diseases such as Alzheimer’s disease (AD) where they are enriched even in serum, making them good candidates for serum biomarkers to enable early detection of AD.

Continuous dimethyl carbonate synthesis from CO2 and methanol over BixCe1−xOδ monoliths: Effect of bismuth doping on population of oxygen vacancies, activity, and reaction pathway

Published: August 2021

AbstractWe evaluated bismuth doped cerium oxide catalysts for the continuous synthesis of dimethyl carbonate (DMC) from methanol and carbon dioxide in the absence of a dehydrating agent. BixCe1−xOδ nanocomposites of various compositions (x = 0.06–0.24) were coated on a ceramic honeycomb and their structural and catalytic properties were examined. The incorporation of Bi species into the CeO2 lattice facilitated controlling of the surface population of oxygen vacancies, which is shown to play a crucial role in the mechanism of this reaction and is an important parameter for the design of ceria-based catalysts. The DMC production rate of the BixCe1−xOδ catalysts was found to be strongly enhanced with increasing Ov concentration. The concentration of oxygen vacancies exhibited a maximum for Bi0.12Ce0.88Oδ, which afforded the highest DMC production rate. Long-term tests showed stable activity and selectivity of this catalyst over 45 h on-stream at 140 °C and a gas-hourly space velocity of 2,880 mL·gcat−1·h−1. In-situ modulation excitation diffuse reflection Fourier transform infrared spectroscopy and first-principle calculations indicate that the DMC synthesis occurs through reaction of a bidentate carbonate intermediate with the activated methoxy (−OCH3) species. The activation of CO2 to form the bidentate carbonate intermediate on the oxygen vacancy sites is identified as highest energy barrier in the reaction pathway and thus is likely the rate-determining step.

Published: August 2021

Abstract
Introduction
The present article describes two interrelated studies that examine gender typicality in young adulthood using a new dual-identity approach.

Methods
Participants were recruited online from March 2020 to February 2021 and reported their perceived similarity to own- and other-gender peers as a way to assess their gender typicality. In study 1, the authors conducted an exploratory factor analysis (EFA) and a confirmatory factor analysis (CFA) to test and validate the Perceived Similarity to Gender Groups Scale in a sample of Italian young adults (n = 571; Mage = 23.9; SD = 3.60). The authors documented the configural, metric, scalar measurement invariance, and validity. In study 2, the Perceived Similarity to Gender Groups Scale adopted in study 1 was used to assess the distribution of different typologies of gender typicality in another sample of Italian young adults who vary in gender and sexual orientation (n = 1126; Mage = 24.3; SD = 3.51).

Results
Results confirmed the structural validity of the Perceived Similarity to Gender Groups Scale, revealing the two-factor structure of the scale. Moreover, results of cluster analysis found different typologies of self-perceptions of gender typicality.

Conclusion
Both studies emphasize the relevance of studying gender typicality in young adulthood through a dual-identity approach, highlighting the relevance of gender and sexual orientations.

Policy Implications
The use of the dual-identity approach has significant social and clinical implications as it represents a more flexible and representative model of the complexity of gender typicality.
The impact of active petroleum system on light hydrocarbons distribution in marine sediments
Authors: Lavrenova E. , Kerimov V. , Mustaev R , Levitskaya M. , Kruglyakova M. 
Published: August 2021

AbstractIntegrated interpretation of regional geochemical data and results of the numerical BM&PSM performed at the east part of the Sea of Azov and northeast part of the Black Sea reveal a correlation between the spatial distribution of light hydrocarbons in seabed sediments and investigated petroleum systems. The obtained results point out that the spatial distribution of gaseous hydrocarbons in marine sediments reflects the geological structure of sedimentary cover, and the maturity of petroleum systems, located within the basins. The origin of background levels and anomalies of light hydrocarbons was explained depending on the present-day petroleum system activity and the structure of overburden rocks.
Single-source-precursor synthesis of porous W-containing SiC-based nanocomposites as hydrogen evolution reaction electrocatalysts
Authors: Yu Zhaoju , Mao Kangwei , Feng Yao 
Published: August 2021

AbstractIn this paper, W-containing SiC-based ceramic nanocomposites were successfully prepared by a polymer-derived ceramic approach using allylhydridopolycarbosilane (AHPCS) as a SiC source, WCl6as a tungsten source, polystyrene (PS) as a pore forming agent as well as divinyl benzene (DVB) as a carbon rich source. High-temperature phase behavior of the W-containing SiC-based ceramics after heat treatment was studied, showing that excessive DVB content in the feed will inhibit the crystallinity of W-containing nanoparticles in the final ceramic nanocomposites. The high specific surface area (SSA) of 169.4–276.9 m2/g can be maintained even at high temperature in the range of 1400–1500 °C, due to the carbothermal reaction which usually occurs between 1300 and 1400 °C. All prepared W-containing SiC-based nanocomposites reveal electrocatalytic activity for the hydrogen evolution reaction (HER). In detail, compared with reversible hydrogen electrode (RHE), the ceramic sample PWA-2-1300 after heat treatment at 1300 °C has the smallest overpotential of 286 mV when the current density is 10 mA·cm−2in acid medium, indicating the promising perspective in the water splitting field.

Abstract
Purpose
Pregnancy-associated plasma protein A (PAPPA) is a metalloproteinase initially described for its role during pregnancy. PAPPA regulates IGF ligands 1 (IGF1) bioavailability through the degradation of IGF-binding protein 4 (IGFBP4). After the cleavage of IGFBP4, free IGF1 is able to bind IGF1 receptors (IGF1R) triggering the downstream signaling. Recently, PAPPA expression has been linked with development of several cancers. No data have been published on thyroid cancer, yet.

Methods
We evaluated PAPPA, insulin-like growth factor (IGF1), IGF1 receptors (IGF1R) and IGF-binding protein 4 (IGFBP4) mRNA expression levels in a “Surgical series” of 94 thyroid nodules (64 cancers, 16 follicular adenomas and 14 hyperplastic nodules) and in a “Cytological series” of 80 nodules from 74 patients underwent to fine-needle aspiration cytology (FNAC). In tissues, PAPPA was also evaluated by western blot.

Results
We found that PAPPA expression was increased in thyroid cancer specimen at mRNA and protein levels and that, adenomas and hyperplastic nodules had an expression similar to normal tissues. When applied on thyroid cytologies, PAPPA expression was able to discriminate benign from malignant nodules contributing to pre-surgical classification of the nodules. We calculated a cut-off with a good specificity (91%) which reached 100% when combined with molecular biology.

Conclusion
These results show that PAPPA could represent a promising diagnostic marker for differentiated thyroid cancer.
