Child–display interaction: Lessons learned on touchless avatar-based large display interfaces
Authors: Rubegni Elisa , Gentile Vito , Malizia Alessio , Sorce Salvatore , Kargas Niko 
Published: October 2020

AbstractDuring the last decade, touchless gestural interfaces have been widely studied as one of the most promising interaction paradigms in the context of pervasive displays. In particular, avatars and silhouettes have proved to be effective in making the touchless capacity of displays self-evident. In this paper, we focus on a child–display interaction approach to avatar-based touchless gestural interfaces. We believe that large displays offer an opportunity to stimulate children’s experiences and engagement; for instance, learning about art is very engaging for children but can bring a number of challenges. Our study aims to contribute to the literature on both pervasive displays and child–computer interaction by reporting the results of a study involving 107 children aged 2 to 10 years. The main purposes of this study were to discover: (1) whether an avatar (movable or immovable) provides interactions that are intuitive for children and therefore help to overcome so-called “affordance blindness”; (2) whether an avatar-based touchless interface makes children’s experiences engaging and enjoyable therefore improving recall of content provided through the interaction (learning about art). The study unveiled relevant outcomes in terms of affordance blindness and two-handed interactions. We provide evidence indicating that chronological age influences the style of child–avatar interaction. Finally, it is suggested that avatars could facilitate the development of new effective educational technologies for young children.
Characterization of digestate microbial community structure following thermophilic anaerobic digestion with varying levels of green and food wastes

Published: October 2020

Abstract
The properties of digestates generated through anaerobic digestion are influenced by interactions between the digester microbial communities, feedstock properties and digester operating conditions. This study investigated the effect of varying initial feedstock carbon to nitrogen (C/N) ratios on digestate microbiota and predicted abundance of genes encoding lignocellulolytic activity. The C/N ratio had a significant impact on the digestate microbiome. Feedstocks with intermediate C/N ratio (20–27) (where higher biomethane potential was observed) showed higher relative abundance of archaea compared to feedstocks with C/N ratios at 17 and 34. Within microbial networks, four microbial clusters and eight connector microorganisms changed significantly with the C/N ratio (P &lt; 0.05). Feedstocks with C/N &lt; 23 were richer in organisms from the family Thermotogaceae and genus Caldicoprobacter and enhanced potential for degradation of maltose, galactomannans, melobiose and lactose. This study provides new insights into how anaerobic digestion conditions relate to the structure and functional potential of digester microbial communities, which may be relevant to both digester performance and subsequent utilization of digestates for composting or amending soil.

AbstractFollowing severe population decline and local extinction due to massive habitat destruction and persecution, wildcats have recently reappeared in several parts of Germany’s low mountain region. It remains unknown how this reemergence occurred, specifically if local populations have been overlooked at low densities or if the species has successfully spread across the highly fragmented anthropogenic landscape. In the central German Rhön Mountains, for instance, wildcats were believed to be extinct during most of the twentieth century, however, the species was recently detected and subsequent genetic monitoring found the presence of a sizeable population. In this study, we used microsatellite and SNP genotypes from 146 wildcat individuals from 2008 to 2017 across a ~ 15,000 km2area in the central German low mountain region to understand the population re-establishment of wildcats in the region. Bayesian clustering and subsequent analyses revealed that animals in the Rhön Mountains appear to be a mix from the two adjacent populations in the North and South of the area, suggesting a recent range expansion from two different directions. Both populations meet in the Rhön Biosphere Reserve, leading to an admixture of the northern, autochthonous, and the southern reintroduced wildcat population. While we cannot completely exclude the possibility of undetected population persistence, the high genetic homogeneity in the central German wildcat population and the lack of any signatures of past population decline in the Rhön favor a scenario of natural expansion. Our findings thus suggest that wildcats are well capable of rapid range expansion across richly structured landscape mosaics consisting of open land, settlements, and forest patches and document the potential of massive non-invasive genetic sampling when aiming to reconstruct the complex population and range dynamics of wildlife.

Published: October 2020

Summary
Background
In the surgical treatment of esophageal cancer, complete tumor resection is the most important factor and determines long-term survival. With an increase in robotic expertise in other fields of surgery, robotic-assisted minimally invasive esophagectomy (RAMIE) was born. Currently, there is a lack of convincing data on the extent of expected benefits (perioperative and oncologic outcomes and/or quality of life). Some evidence exists that patients’ overall quality of life and physical function improves, with less fatigue and pain 3 months after surgery. We aimed to review the available literature regarding robotic esophagectomy, compare perioperative, oncologic, and quality of life outcomes with open and minimally invasive approaches, and give a brief overview of our standardized four-arm RAMIE technique and explore future directions.

Methods
A Medline (PubMed) search was conducted including the following key words: esophagectomy, minimally invasive esophagectomy, robotic esophagectomy, Ivor Lewis and McKeown. We present the history, different techniques used, outcomes, and the standardization of robotic esophagectomy.

Results
Robotic esophagectomy offers a steeper learning curve with fewer complications but comparable oncological results compared to conventional minimally invasive esophagectomy.

Conclusions
Available studies suggest that RAMIE is associated with benefits regarding length of stay, clinical outcomes, and quality of life—if patients are treated in an experienced center with a standardized technique for robotic esophagectomy—making it a potentially beneficial tool in the treatment of esophageal cancer. However, center-wide standardization and prospective data collection will be a necessity to prove superiority of robotic esophagectomy.
Bifurcation and dynamic behavior analysis of a rotating cantilever plate in subsonic airflow
Authors: Ma Li , Yao Minghui , Zhang Wei , Cao Dongxing 
Published: October 2020

AbstractTurbo-machineries, as key components, have a wide utilization in fields of civil, aerospace, and mechanical engineering. By calculating natural frequencies and dynamical deformations, we have explained the rationality of the series form for the aerodynamic force of the blade under the subsonic flow in our earlier studies. In this paper, the subsonic aerodynamic force obtained numerically is applied to the low pressure compressor blade with a low constant rotating speed. The blade is established as a pre-twist and presetting cantilever plate with a rectangular section under combined excitations, including the centrifugal force and the aerodynamic force. In view of the first-order shear deformation theory and von-Kármán nonlinear geometric relationship, the nonlinear partial differential dynamical equations for the warping cantilever blade are derived by Hamilton’s principle. The second-order ordinary differential equations are acquired by the Galerkin approach. With consideration of 1:3 internal resonance and 1/2 sub-harmonic resonance, the averaged equation is derived by the asymptotic perturbation methodology. Bifurcation diagrams, phase portraits, waveforms, and power spectrums are numerically obtained to analyze the effects of the first harmonic of the aerodynamic force on nonlinear dynamical responses of the structure.

AbstractThe large number of available MRI sequences means patients cannot realistically undergo them all, so the range of sequences to be acquired during a scan are protocolled based on clinical details. Adapting this to unexpected findings identified early on in the scan requires experience and vigilance. We investigated whether deep learning of the images acquired in the first few minutes of a scan could provide an automated early alert of abnormal features. Anatomy sequences from 375 CMR scans were used as a training set. From these, we annotated 1500 individual slices and used these to train a convolutional neural network to perform automatic segmentation of the cardiac chambers, great vessels and any pleural effusions. 200 scans were used as a testing set. The system then assembled a 3D model of the thorax from which it made clinical measurements to identify important abnormalities. The system was successful in segmenting the anatomy slices (Dice 0.910) and identified multiple features which may guide further image acquisition. Diagnostic accuracy was 90.5% and 85.5% for left and right ventricular dilatation, 85% for left ventricular hypertrophy and 94.4% for ascending aorta dilatation. The area under ROC curve for diagnosing pleural effusions was 0.91. We present proof-of-concept that a neural network can segment and derive accurate clinical measurements from a 3D model of the thorax made from transaxial anatomy images acquired in the first few minutes of a scan. This early information could lead to dynamic adaptive scanning protocols, and by focusing scanner time appropriately and prioritizing cases for supervision and early reporting, improve patient experience and efficiency.

Authors: Orlandi Fabio , Ruga Luigia , Fornaciari Marco 
Published: October 2020

AbstractIn order to estimate the impact of climate change on the phenological parameters and to compare them with the historical record, a decision support system (DSS) has been applied employing a Phenological Modelling Platform. Biological observations of two willow species (Salix acutifolia and smithiana Willd) in 3 gardens at different altitudes located in Central Italy were utilized to identify suitable phenological models related to four main vegetative phase timings (BBCH11, BBCH91, BBCH 94, BBCH95), and male full flowering (BBCH 65) clearly identifiable in these species. The present investigation identifies the best phenological models for the main phenophases allowing their practical application as real-time monitoring and plant development prediction tools. Sigmoid model revealed high performances in simulating spring vegetative phases, BBCH11 (First leaves unfolded), and BBCH91 (Shoot and foliage growth completed). Salix acutifolia Willd. development appeared to be more related to temperature amount interpreted by phenological models in comparison to Salix smithiana Willd. above all during spring (BBCH11 and 91), probably due to a different grade of phenotypic plasticity between the 2 considered species.
About time: the narrowing gender wage gap in Austria
Authors: Böheim René , Fink Marian , Zulehner Christine 
Published: October 2020

AbstractWe examine the gender wage gap in Austria from 2005 to 2017 using data from EU-SILC. The raw gap of hourly wages declined from 18.6 log points in 2005 to 14.9 log points in 2017. We use standard decomposition techniques that correct for differences in the distributions of human capital and other variables between men and women. Decompositions of the wage gap indicate that both the explained and the unexplained part of the gender wage gap decreased substantially over the last ten years. Using the approach developed by Neumark (J Hum Resour 22:279–295, 1988), the unexplained wage gap shrank from 8.7 log points in 2005 to 5.1 log points in 2017. The main reason for the decline in wage differences was the relative improvement of women’s observed and unobserved characteristics.
Individual variability in stable isotope turnover rates of epidermal mucus according to body size in an omnivorous fish
Authors: Winter Emily R. , Britton J. Robert 
Published: October 2020

AbstractEpidermal mucus (‘mucus’) is increasingly applied to fish ecological studies based on stable isotope analysis (SIA) due to its non-invasive collection. However, knowledge on mucus SI turnover rates of individual fish remains limited, including uncertainty over how they are influenced by fish body sizes. Here, a diet switch experiment predicted mucus SI turnover rates (δ13C and δ15N) as a function of time using samples taken over 200 days from 10 individually tagged common carp Cyprinus carpio covering two size groups. Non-linear mixed effects models revealed rapid turnover of both δ13C and δ15N (T50: 2–5 days; T95: 9–22 days); δ15N turnover rates were slower for the larger cohort, while δ13C turnover rates were independent of body size. Within size groups, turnover rates were not expected to vary between individuals. These experimental results suggest that due to these fast turnover rates, epidermal mucus can provide insights into the diets of fish over very short timeframes, although for δ15N the body size of the fish needs consideration.

Published: October 2020

AbstractThe projected population growth implies an increased food demand with a severe impact on Earth’s natural resources. Improving crops yield without compromising the environment will be one of the main challenges of the next decades. Among the practices that can promote sustainable agriculture, organic fertilizers, and seaweeds in particular, are receiving growing attention. The aim of the current study was to test two macroalgae (Chaetomorphasp. andCystoseirasp.), one microalga (ChlorellaCH2) and Bioguano (a mixture of macroalgae, spirulina, and guano) as organic fertilizers for the growth of barley seedlings. Remarkable plant growth was obtained on Bioguano, with seedlings showing a comparable total biomass yield with respect to the positive control plants on mineral fertilizer. Plants growth on macroalgae was reduced, even if inChaetomorphasp. not significantly compared to the positive control. Plants growth onChlorellaCH2 was close to that of the negative control (only water). Plants on Bioguano attained high uptake efficiencies of N (60%) and K (41%). Plants on macroalgae showed high N, and especially P (about 30%) uptake efficiency. Our results suggest a high potential for Bioguano and, to a lesser extent, for macroalgae without any synthetic fertilizer application to be used as growing substrates for crops.

Abstract

Background
Clínica Bienestar is a comprehensive HIV primary care clinic for Spanish-speaking Latinx with opioids use disorders (OUD). This article describes the barriers and trajectories to HIV viral suppression for Puerto Ricans with a transnational profile and dual diagnoses (HIV and OUD), and the strategies applied to increase retention in care.

Methods
Case study methodology was used to select two patient life histories that illustrate the most common pathways to success in reducing HIV viral load to undetectable and achieving OUD long-term recovery.

Results and Discussion
Patients’ major challenges included: (1) Persistent migrating while seeking substance use treatment services with limited or no support from their sending and hosting communities; (2) Intersectional stigmas; (3) Untreated trauma; (4) Language and cultural barriers. Clínica Bienestar’s service model included ten strategies to retain patients in care (e.g., Case management to identify cases with high social isolation), six emerged as central to addressing transnational challenges.
Covid-19 and the Apocalypse: Religious and Secular Perspectives
Authors: Dein Simon 
Published: October 2020

AbstractThe current Covid-19 pandemic has led to existential crises. One way of finding meaning in this is through apocalyptic narratives. We differentiate between religious (based upon eschatology) and secular apocalypticism (based upon radical political and economic change) and argue that both are to be found in the wake of Covid-19 infection. For religious believers, the apocalypse signifies the rapture of the faithful into heaven while those on earth will undergo the tribulations. For secular believers, the apocalypse signifies sociopolitical change. The paper ends by speculating upon the socio-political and economic changes during and after the pandemic- the New Jerusalem.

Published: October 2020

AbstractSchool burnout symptoms are prevalent among upper secondary education students, but thus far, very little is known about the background of these symptoms. The present study examined the extent to which school burnout symptoms (i.e., exhaustion and cynicism) among upper secondary education students have their roots in primary and lower secondary school and whether early antecedents of school burnout symptoms could be identified. The sample consisted of 1544 Finnish students followed up four times (Time1–Time 4) from the end of primary school (T1; mean age 12.74 and range 11.71–14.20) to the first year of upper secondary education (T4; mean age 16.66 and range 15.55–18.39). The results of latent growth curve modeling showed that school burnout symptoms in upper secondary education were predicted by the level of school burnout symptoms at the end of primary school and by an increase in these symptoms across the transition from primary school through lower secondary school. In addition, psychological well-being, academic skills, and gender were found to contribute to the prediction of school burnout symptoms. Overall, the present study suggest that potential warning signs of school burnout should not be ignored and attention should be directed to earlier education phases.
Use of silver–bentonite in sorption of chloride and iodide ions
Authors: Buzetzky Dóra , Nagy Noémi M. , Kónya József 
Published: October 2020

AbstractAg–bentonite was prepared by ion exchange process to sorb iodide and chloride ions in batch experiments. The modified bentonite was examined with XRF and XRD. 75% of the cation exchange capacity was exchanged by silver ions. It was found that the sorption of chloride ions is an exothermic precipitation process because the solubility decreases with increasing temperature. In the case of iodide sorption, the dissolution of AgI was observed under high concentration of non-radioactive iodide ions, which is well known in analytical chemistry. The phenomenon occurs not only in the bulk aqueous phase but also in the interlayer space of montmorillonite.
Každyj den’ turist *otdoxnul na pljaže. An event-related potentials study on the processing of aspectual violation in Russian iterative sentences
Authors: Zeller Jan Patrick , Clasmeier Christina 
Published: October 2020

Abstract
The treatment of verbal aspect in Russian grammar and its interaction with lexical semantics are controversial matters. We address these issues from a psycholinguistic perspective. We conducted an EEG study with 14 native Russian speakers processing 160 sentences in the unrestrictedly iterative meaning; the sentences were either correct or contained semantic, morpho-syntactic, or aspectual violations (e.g., Každyj večer otec *zasnulpfvna divane. ‘Every evening the father *fell asleep on the sofa’). Processing the aspectual violation resulted in a P600, which is typical for processing morpho-syntactic violations and usually is interpreted as an index of difficulties in syntactic (re-)analysis, while an N400, which is typical for processing lexico-semantic violations, could not be observed. Our results show that Russian speakers must make more effort to analyze aspectually incorrect sentences compared with aspectually correct sentences. Processing aspectual violations in Russian clearly resembles processing of morpho-syntactic violations. This is in line with the interpretation of aspect as a typical grammatical category.

AbstractAmong the numerous clean-up techniques for water treatment, sorption methods are widely used for the removal of trace metals. Phragmites australis is a macrophyte commonly used in constructed wetlands for water purification, and in the last decades, its use as biosorbent has attracted increasing attention. In view of a circularly economy approach, this study investigated improvement of trace metal removal by recycling the biomass of P. australis colonizing a constructed wetland, which operates as post-treatment of effluent wastewater from an activated sludge plant serving the textile industrial district of Prato (Italy). After the annual mowing of the reed plants, the biomass was dried and blended to derive a sustainable and eco-friendly biosorbent and its sorption capacity for Fe, Cu, and Zn was investigated comparing the batch system with the easier-to-handle column technique. The possibility of regeneration and reuse of the biosorbent was also evaluated. The biomaterial showed an interesting sorption capacity for Cu, Fe, and Zn, both in batch and in column experiments, especially for Fe ions. The immobilization of the biosorbent in column filters induced some improvement in the removal efficiency, and, in addition, this operation mode has the advantage of being much more suitable for practical applications than the batch process.
