Abstract
Lack of knowledge in the underlying data distribution in distributed large-scale data can be an obstacle when issuing analytics & predictive modelling queries. Analysts find themselves having a hard time finding analytics/exploration queries that satisfy their needs. In this paper, we study how exploration query results can be predicted in order to avoid the execution of ‘bad’/non-informative queries that waste network, storage, financial resources, and time in a distributed computing environment. The proposed methodology involves clustering of a training set of exploration queries along with the cardinality of the results (score) they retrieved and then using query-centroid representatives to proceed with predictions. After the training phase, we propose a novel refinement process to increase the reliability of predicting the score of new unseen queries based on the refined query representatives. Comprehensive experimentation with real datasets shows that more reliable predictions are acquired after the proposed refinement method, which increases the reliability of the closest centroid and improves predictability under the right circumstances.

AbstractRight ventricular biopsy represents the gold standard for the assessment of myocardial fibrosis and collagen content. This invasive technique, however, is accompanied by perioperative complications and poor reproducibility. Extracellular volume (ECV) measured through cardiovascular magnetic resonance (CMR) has emerged as a valid surrogate method to assess fibrosis non-invasively. Nonetheless, ECV provides an overestimation of collagen concentration since it also considers interstitial space. Our study aims to investigate the feasibility of estimating total collagen volume (TCV) through CMR by comparing it with the TCV measured at histology. Seven healthy Landrace pigs were acutely instrumented closed-chest and transported to the MRI facility for measurements. For each protocol, CMR imaging at 3T was acquired. MEDIS software was used to analyze T1 mapping and ECV for both the left ventricular myocardium (LVmyo) and left ventricular septum (LVseptum). ECV was then used to estimate TCVCMR at LVmyo and LVseptum following previously published formulas. Tissues were prepared following an established protocol and stained with picrosirius red to analyze the TCVhisto in LVmyo and LVseptum. TCV measured at LVmyo and LVseptum with both histology (8 ± 5 ml and 7 ± 3 ml, respectively) and T1-Mapping (9 ± 5 ml and 8 ± 6 ml, respectively) did not show any regional differences. TCVhisto and TCVCMR showed a good level of data agreement by Bland–Altman analysis. Estimation of TCV through CMR may be a promising way to non-invasively assess myocardial collagen content and may be useful to track disease progression or treatment response.

AbstractCombinations of wood and metal are interesting hybrid composite materials, joining together the low density of wood with the stiffness and strength of metals. Different types of adhesives are used to connect wood and metal elements, but the compatibility between adhesives used and load-bearing materials must be sufficient, which often is challenging. In adhesive bonding technology, surface treatments are a crucial step in the process. In this study, an atmospheric plasma discharge was employed to enhance the adhesion strength of joints between common beech (Fagus sylvatica L.) wood, metals (steel and aluminum alloy), and four different types of adhesives. The optical properties of plasma discharges and its influence on treated substrates’ surface morphology depended on the inherent properties of the treated materials. X-ray photoelectron spectroscopy revealed the surface oxidation of all the materials after plasma treatment. Consequently, the surface free energy of all materials increased as well. The positive effect of the plasma treatment on the tensile shear strength of single-lap joints shows a high potential of atmospheric plasma treatment technology for enhancement of adhesives strength of joints combining wooden elements, wood and steel, or wood and aluminum alloys. In addition to that, expensive epoxy and polyurethane adhesives could be replaced by more affordable polyvinyl acetate and melamine-urea-formaldehyde adhesives, and still perform at equal levels if the plasma was applied prior to bonding.
Brief Report: Social Anxiety in Autism Spectrum Disorder is Based on Deficits in Social Competence

Published: May 2020

AbstractThis study differentially examined the relation between two clinical constructs: “social anxiety” and “social competence” in autism spectrum disorder (ASD). Employing two questionnaires (SASKO; IU), individuals with ASD (n = 23) showed increased scores of SOCIAL ANXIETY (SASKO) and of INTOLERANCE OF UNCERTAINTY (IU), compared to a non-clinical comparison group (NC; n = 25). SOCIAL ANXIETY scores were equally increased for ASD and a reference population of individuals with social anxiety disorder (SAD; n = 68). However, results showed increased SOCIAL COMPETENCE DEFICITS in ASD compared to SAD and NC groups. This study allows drawing the conclusion that social anxiety symptoms in ASD can be traced back to autism-specific deficits in social skills and are therefore putatively based on different, substantially “deeper” implemented cognitive mechanisms.
Fixing and extending some recent results on the ADMM algorithm

AbstractWe investigate the techniques and ideas used in Shefi and Teboulle (SIAM J Optim 24(1), 269–297, 2014) in the convergence analysis of two proximal ADMM algorithms for solving convex optimization problems involving compositions with linear operators. Besides this, we formulate a variant of the ADMM algorithm that is able to handle convex optimization problems involving an additional smooth function in its objective, and which is evaluated through its gradient. Moreover, in each iteration, we allow the use of variable metrics, while the investigations are carried out in the setting of infinite-dimensional Hilbert spaces. This algorithmic scheme is investigated from the point of view of its convergence properties.
Slow train coming: an anti-CCN2 strategy reverses a model of chronic overuse muscle fibrosis
Authors: Leask Andrew 
Published: May 2020

AbstractOne of the first targets proposed as an anti-fibrotic therapy was CCN2. Proof of its involvement in fibrosis was initially difficult, due to the lack of appropriate reagents and general understanding of the molecular mechanisms responsible for persistent fibrosis. As these issues have been progressively resolved over the last twenty-five years, it has become clear that CCN2 is a bone fide target for anti-fibrotic intervention. An anti-CCN2 antibody (FG-3019) is in Phase III clinical trials for idiopathic pulmonary fibrosis and pancreatic cancer, and in Phase II for Duschenne’s muscular dystrophy. An exciting paper recently published by Mary Barbe and the Popoff group has shown that FG-3019 reduces established muscle fibrosis (Barbe et al., FASEB J 34:6554–6569, 2020). Intriguingly, FG-3019 blocked the decreased expression of the anti-fibrotic protein CCN3, caused by the injury model. These important data support the notion that targeting CCN2 in the fibrotic microenvironment may reverse established fibrosis, making it the first agent currently in development to do so.

AbstractDowny mildew on garden cress caused byPerofascia lepidiihas become prevalent in organic seed producing areas of Germany resulting in limited seed production and high yield losses. Downy mildew occurrence in young plants in fields that have never been cultivated with garden cress raised questions about infested seeds and soils as sources of the primary inoculum and the role of other members of the plant family Brassicaceae as hosts ofP. lepidii. To address these questions 31 seed lots from nine garden cress fields were examined for contamination usingP. lepidiispecies-specific PCR assays. DNA ofP. lepidiiwas detected in 17 seed lots out of 31. In bioassays no disease was observed on plants grown from infested seed lots but in a few plants grown from seeds. The significance of soilborne inoculum was investigated by assessing disease incidence in plants grown in soil samples. Garden cress with downy mildew symptoms were recorded when plants were grown in pathogen infested soil samples. The results show thatP. lepidiiis able to survive in the soil and can be a primary inoculum source for downy mildew disease. Oospores formed in infected plants underpin the role of these survival structures that get incorporated into soil after harvesting.

Potential Use of Incineration Bottom Ash in Construction: Evaluation of the Environmental Impact
Authors: Kalbe Ute , Simon Franz-Georg 
Published: May 2020

AbstractKnowledge of the long-term leaching behavior of potentially harmful substances is crucial for the assessment of the environmental compatibility of reusing municipal solid-waste incineration bottom ash (MSWI BA) in construction, i.e., as a road base layer. BA fractions obtained from wet-processing aiming at the improvement of environmental quality were used to investigate the mobility of relevant substances. Eluates from laboratory-scaled leaching procedures (column percolation and lysimeters) were analyzed to learn about the long-term release of substances. Unsaturated conditions and artificial rainwater (AR) were used in the lysimeter tests to simulate field conditions. In addition, batch test eluates were generated at usual liquid-to-solid ratios (L/S) for compliance testing purposes. A variety of cations and anions was measured in the eluates. The wet treatment reduces the leaching of chloride and particularly sulfate by more than 60%. The release of typical contaminants for the treated MSWI BA such as the heavy metals Cu and Cr was well below 1% in the conducted leaching tests. An increase in the Sb concentration observed in the lysimeter experiments starting at L/S 0.75 L/kg and in the column experiment at L/S 4 L/kg is assumed to be related to decreasing concentrations of Ca and thus to the dissolution of sparingly soluble calcium antimonate. The same leaching mechanism applies with V, but the concentration levels observed are less critical regarding relevant limit values. However, on the long term the behavior of Sb could be problematic for the application of MSWI BA in construction.

Published: May 2020

AbstractParrots (Psittaciformes) are among the most endangered groups of birds today and remain threatened by habitat loss and exploitation for the live bird trade. Under such conditions, reliable and non-invasive monitoring techniques are crucial for successful conservation measures. In this study, we developed a panel of 86 high quality SNPs for genotyping endangered sun parakeets (Aratinga solstitialis) in Guyana, which form one of the last known breeding populations of this South American species in the wild. Genotyping was tested on different types of samples (blood, feathers, feces, beak and cloacal swabs). While blood performed best, feathers and feces also yielded reliable results and could thus be used as non-invasive sources of DNA for future population monitoring. Discriminant Analysis of Principal Components (DAPC) on genotypes revealed that Guyanese sun parakeets clustered separately from other psittacine species as well as conspecifics from a captive population. A priori known first-order kinships were also adequately detected by the SNP panel. Using a series of experimental contaminations, we found that contamination from other psittacine species and slight contamination (~ 10%) from conspecifics did not prevent successful genotyping and recognition of individuals. We show that instances of higher conspecific contamination (~ 50%) can be detected through an increased level of heterozygosity that falls outside the distribution of uncontaminated samples.
Movement patterns and habitat selection during dispersal in Eurasian lynx
Authors: Herrero Annika , Heikkinen Juha , Holmala Katja 
Published: May 2020

AbstractNatal dispersal affects the gene flow, distribution, dynamics and social structure of a population. In many solitary mammals, dispersal is often male-biased, while females may remain philopatric. For the Eurasian lynx (Lynx lynx), dispersal distances vary greatly and may be explained by sex or by habitat characteristics, such as fragmentation. Juvenile lynx habitat selection during dispersal has not been studied before, but resident lynx select heterogeneous forested habitats and avoid human settlements and infrastructure through distinct temporal activity patterns. We studied movement patterns and habitat selection during the dispersal of 22 Eurasian lynx (7 females, 15 males) in Finland. We found no differences between the sexes in the onset age, duration, distance, route or route linearity. Dispersal took place mostly during the evening and at night but also during the day. Of the four most used habitats, the mixed forests and transitional woodlands were used more frequently than would be expected according to their availability, and conifer forests and fields less than would be expected. Housing and other human infrastructure, including roads, were the least frequently used categories. There was a highly significant difference between the used and available habitats in general. The lynx selected the habitat more carefully during the day than during the night.

Women’s Preferences for Sexual Dimorphism in Faces: Data from a Sample of Arab Women
Authors: Alharbi Sarah A. H. , Holzleitner Iris J. , Lee Anthony J. , Saribay S. Adil , Jones Benedict C. 
Published: May 2020

AbstractMany previous studies have investigated the effects of manipulating sexually dimorphic shape characteristics in face images on attractiveness judgments. However, results have been mixed and show considerable cross-cultural variability, particularly for women’s judgments of men’s facial attractiveness. Because very little research has investigated face preferences in Arab samples, we assessed Arab women’s preferences for sexually dimorphic face shapes (study 1) and the effect of sexually dimorphic face shapes on Arab women’s dominance perceptions (study 2). Analyses showed that Arab women preferred feminized versions of both women’s and men’s faces over masculinized versions (study 1, N = 272) and that masculinizing face shape had a positive effect on Arab women’s perceptions of the dominance of men, but not women (study 2, N = 270). These image manipulations did not have a significant effect on perceptions of trustworthiness, however (study 3, N = 434). Collectively, these results suggest that Arab women prefer relatively feminine face shapes in potential mates that they perceive as being low dominance. We discuss some directions for future research on the ultimate function of Arab women’s preferences for sexual dimorphism in faces
A multi-model approach toward understanding iron fouling at rock-fill drainage sites along roadways in New Hampshire, USA
Authors: Lombard Melissa A. , Lombard Pamela J. , Brown Craig J. , Degnan James R. 
Published: May 2020

AbstractFactors affecting iron fouling in wet areas adjacent to roadways were investigated by collecting field rock cut and aqueous physicochemical data; developing exploratory predictive models; and developing geochemical models. Basic data included the identification of iron fouling from aerial imagery and field visits at 374 New Hampshire rock cut locations, and their associated rock-fill sites. Based on field water quality measurements from wet areas at 36 of the rock-fill sites, the occurrence of iron fouling was associated with higher values of specific conductance, lower concentrations of dissolved oxygen and lower pH compared to areas without iron fouling. A statistical model, using boosted regression trees, was developed to predict the occurrence of iron fouling in wet areas adjacent to roadways where rock-fill from nearby rock cuts was used in roadway construction. The model was used to develop a continuous iron fouling probability map for the state of New Hampshire that can be used to better understand the occurrence of iron fouling. Geochemical models illustrate how iron fouling of waters increases along roadways built with fill from sulfidic rock cuts as a result of acid generation from pyrite dissolution and ferrous iron (Fe2+) oxidation and increases in areas with greater specific conductance from deicing runoff caused by cation exchange. More iron is precipitated as goethite in simulations that include pyrite, and in simulations with deicing salts added, indicating that rock-fill sites with rocks that contain pyrite and water with greater salt content could have enhanced iron fouling.
Rüstungskontrolle ohne Verträge?
Authors: Heinrich Jens 
Published: May 2020

ZusammenfassungDie vertragsbasierte nukleare Rüstungskontrolle steht gegenwärtig vor enormen Herausforderungen. Besonders in Südasien konnten auf Verträgen beruhende und verbindliche Steuerungsansätze bisher nicht etabliert werden und zu einer Verlangsamung der Aufrüstung und zur Stabilisierung der Beziehungen zwischen den beiden Kernwaffenstaaten Indien und Pakistan beitragen. Gleichzeitig wird in der Literatur unverbindliche und informelle Rüstungskontrolle als potentielle Alternative nur begrenzt reflektiert, was mit Blick auf die Forschung zu informellen Ansätzen verwundert. Ausgehend von diesem Befund schlage ich eine Fokussierung auf die in den 1960er Jahren entwickelte gradualistische Strategie vor. Mein Argument ist, dass diese einen Beitrag zur Stabilität zwischen Indien und Pakistan leisten kann. Für diesen Zweck wird ein Analyserahmen entwickelt, der sowohl konkrete Anwendungsbereiche als auch Kriterien und Bedingungen für die gradualistische Strategie offenlegt. Der Aufsatz liefert somit nicht nur spezifische Ideen und Impulse für Rüstungskontrollansätze in Südasien, sondern bietet auch Anknüpfungspunkte für Arbeiten zu anderen regionalen Zusammenhängen und trägt so zu einer Erweiterung der Rüstungskontrollperspektive bei.

Opportunism, Identification Asymmetry, and Firm Performance in Chinese Interorganizational Relationships
Authors: Lee Lucy Sojung , Zhong Weiguo 
Published: May 2020

ABSTRACTExtant literature focuses on within-dyad opportunism (i.e., transgression of the norms of a specific business relationship) while neglecting pro-relational opportunism (i.e., transgression of societal norms to benefit the relationship), resulting in limited understanding of their different effects. We argue that opportunism is a significant threat to the identity of business partners and boundary spanners which results in different relational dynamics at different levels, that is, Type-I (i.e., interorganizational identification squeezing out interpersonal identification) and Type-II identification asymmetry (i.e., interpersonal identification dominating interorganizational identification). Identification asymmetry further mediates the effects of opportunism on exchange performance. Based on a matched manufacturer–supplier sample, we find strong support to the hypotheses. Moreover, distributive fairness aggravates the effect of pro-relational opportunism on identification asymmetry, while interactive fairness mitigates it. Our research provides more nuanced between-level findings on identification in interorganizational settings, and cautions against firms’ tendency toward Machiavellian reasoning when they face the temptation of complicit behavior for organizational gains.
