Correlating Coating Quality of Coverage with Rheology for Mica-Based Paints
Authors: Anderson Jacob , Shori Shailesh , Jabbari Esmaiel , Ploehn Harry J. , Gadala-Maria Francis , Priftis Dimitrios 
Published: February 2021

AbstractThis paper examines the relationship between rheology and the qualitative appearance of dried, mica-based paint coatings used in the aerospace industry. The goal is to identify key rheological characteristics indicative of poor coating visual appearance, providing a screening tool to identify unsatisfactory paint formulations. Four mica paints were studied, having coating visual appearances ranging from very poor to very good. Strain sweeps indicated that the poor-quality paints have a smaller % strain midpoint in the linear visco-elastic range; while the good-quality paints have a lower G’/G” cross-over point in frequency sweeps. Thixotropy experiments utilizing single and multiple-loop hysteresis cycles plotting shear stress as a function of shear rate showed that the base mica paints with good appearance had nearly constant, reversible profiles in the forward and the backward directions; while the mica paints with poor appearance were irreversible with a noticeable gradual change in shear stress as more loops are run. The difference in area between the forward and the reverse curves was determined, leading to a quantifiable criterion that can differentiate good paints from poor paints with significance testing. This work would establish the first rheology model using hysteresis loops to predict the visual properties of mica-based paints.
Measuring Social Norms in Economics: Why It Is Important and How It Is Done
Authors: Nosenzo Daniele , Görges Luise 
Published: February 2021

Abstract
Experimental economics offers new tools for the measurement of social norms. In this article, we argue that these advances have the potential to promote our understanding of human behavior in fundamental ways, by expanding our knowledge beyond what we learn by simply observing human behavior. We highlight how these advancements can inform not only economic and social theory, but also policymaking.We then describe and critically assess three approaches used in economics to measure social norms. We conclude our overview with a list of recommendations to help empirical researchers choose among the different tools, depending on the nature and constraints of their research projects.
The Legitimacy of Groups: Toward a We-Reasoning View
Authors: Tam Agnes 
Published: February 2021

Abstract
In liberal political philosophy, a prevalent view holds that groups are typically voluntary associations. Members of voluntary associations can accept, revise or reject group practices as a matter of choice. In this article, I challenge this view. Appealing to the concept of joint commitment developed in philosophy of social science, I argue that individuals who jointly commit their wills to a goal or a belief form a ‘We’-group. Members of ‘We’-groups are under an obligation to defer to ‘Our’ will embodied in ‘Our’ norms as a matter of course. I further show the ubiquity of We-groups. This joint commitment account of group authority raises a much-overlooked question of group legitimacy: Do members have good reasons to obey norms of their group? I show that state-centric views of legitimacy are inapt to answer it. A group-centric view, revived from the old communitarian literature, is defended.
On How Expertise Ascriptions Work
Authors: Quast Christian 
Published: February 2021

Abstract
Expertise is often ascribed to persons who are considered exceptionally competent in a particular subject matter. In contrast to this traditional approach, the present paper introduces a contextual understanding of expertise ascriptions. More precisely, this paper introduces two different kinds of contextuality by advancing and advocating the thesis that expertise ascriptions are true if and only if their content within their context of use is true against standards in the context of assessment. This means that expertise ascriptions have indexical content and are also assessment-sensitive. On this basis, a definition of expertise will be developed which outlines a series of conditions for what it takes to be an expert.
Expertise as a Form of Knowledge: A Response to Quast
Authors: Fuller Steve 
Published: February 2021

Abstract
Christian Quast has presented what he describes as a ‘role-functional’ account of expertise as a form of knowledge that purports to take into account prior discussions within recent analytic social epistemology and allied fields. I argue that his scrupulousness results in a confused version of the role-functional account, which I try to remedy by presenting a ‘clean’ account that clearly distinguishes such an account from what Quast calls a ‘competence-driven’ one. The key point of my account is that ‘competence’ pertains to knowledge in closed systems and ‘expertise’ in open systems. I observe that the invocation of ‘reliability’ as an epistemic standard simply serves to confuse the difference between the competence-driven and role-functional accounts.
Varieties of Tribalism in the Laboratory
Authors: Hargreaves Heap Shaun P. 
Published: February 2021

Abstract
This paper uses evidence from laboratory experiments to identify a variety of tribalisms. This is important because some tribalisms encourage zerosum thinking and others do not; and some are not developed by Buchanan. This, in turn, supplies new insights into Buchanan’s project of identifying the kinds of environment that encourage his sense of moral progress. In particular, current levels of inequality become a significant barrier to moral progress not only because they create an economic form of tribalist zero-sum thinking but they also undermine the scope for positive-sum.
The Meaning of Mass Atrocities Beyond Our Moral Fate
Authors: Morrow Paul 
Published: February 2021

Abstract
Philosophical accounts of moral progress commonly acknowledge the problem of mass atrocities. But the implications of such events for our ability to perceive, and achieve, progress are rarely considered in detail. This paper aims to address this gap. The paper takes as its starting point Allen Buchanan’s evolutionary theory of moral progress in his 2020 book Our Moral Fate. Through critical analysis of Buchanan’s theory, the paper shows that moral philosophers seeking to draw evidence from atrocities must pay closer attention to social scientific research into such crimes, and particularly to findings concerning the diverse motives, intentions, and ideological influences on perpetrators. At the same time, the paper suggests that mass atrocities exhibit the action-guiding influence not only of moral norms, but also of social and legal norms. The paper concludes by briefly considering the significance of mass atrocities for theories of moral progress beyond Our Moral Fate.
Why do women become teachers while men don’t?
Authors: Carroll David , Parasnis Jaai , Tani Massimiliano 
Published: February 2021

Abstract
Across countries, almost all primary and pre-primary teachers are women while few men in the occupation tend to specialise in secondary schooling and administration. We investigate the decision to become a teacher versus alternative occupations for graduates in Australia over the past 15 years. We find that this gender distribution reflects relative returns in the labour market: women with bachelor qualifications receive higher returns in teaching, while similarly educated men enjoy substantially higher returns in other occupations. We also find evidence that schools which can, and do, make higher wage offers successfully attract more male teachers as well as more female teachers with a degree in science, technology, engineering, and mathematics. These results are consistent with the predictions of theoretical models of self-selection of intrinsically motivated workers.
Attention based convolutional network for automatic sleep stage classification

Published: February 2021

Abstract
Sleep staging is an important basis for diagnosing sleep-related problems. In this paper, an attention based convolutional network for automatic sleep staging is proposed. The network takes time-frequency image as input and predict sleep stage for each 30-s epoch as output. For each CNN feature maps, our model generate attention maps along two separate dimensions, time and filter, and then multiplied to form the final attention map. Residual-like fusion structure is used to append the attention map to the input feature map for adaptive feature refinement. In addition, to get the global feature representation with less information loss, the generalized mean pooling is introduced. To prove the efficacy of the proposed method, we have compared with two baseline method on sleep-EDF data set with different setting of the framework and input channel type, the experimental results show that the paper model has achieved significant improvements in terms of overall accuracy, Cohen’s kappa, MF1, sensitivity and specificity. The performance of the proposed network is compared with that of the state-of-the-art algorithms with an overall accuracy of 83.4%, a macro F1-score of 77.3%, κ = 0.77, sensitivity = 77.1% and specificity = 95.4%, respectively. The experimental results demonstrate the superiority of the proposed network.

Published: February 2021

Abstract
The identification of gastrointestinal (GI) motility disorders requires the evaluation of regional GI transit, and the development of alternative methodologies in animals has a significant impact on translational approaches. Therefore, the purpose of this study was to validate an easy and low-cost methodology (alternate current biosusceptometry – ACB) for the assessment of regional GI transit in rats through images. Rats were fed a test meal containing magnetic tracer and phenol red, and GI segments (stomach, proximal, medial and distal small intestine, and cecum) were collected to assess tracer’s retention at distinct times after ingestion (0, 60, 120, 240, and 360 min). Images were obtained by scanning the segments, and phenol red concentration was determined by the sample’s absorbance. The temporal retention profile, geometric center, gastric emptying, and cecum arrival were evaluated. The correlation coefficient between methods was 0.802, and the temporal retention of each segment was successfully assessed. GI parameters yielded comparable results between methods, and ACB images presented advantages as the possibility to visualize intrasegmental tracer distribution and the automated scan of the segments. The imaging approach provided a reliable assessment of several parameters simultaneously and may serve as an accurate and sensitive approach for regional GI research in rats.

Abstract

Objectives
Assessment of children’s laboratory test results requires consideration of the extensive changes that occur during physiological development and result in pronounced sex- and age-specific dynamics in many biochemical analytes. Pediatric reference intervals have to account for these dynamics, but ethical and practical challenges limit the availability of appropriate pediatric reference intervals that cover children from birth to adulthood. We have therefore initiated the multi-center data-driven PEDREF project (Next-Generation Pediatric Reference Intervals) to create pediatric reference intervals using data from laboratory information systems.

Methods
We analyzed laboratory test results from 638,683 patients (217,883–982,548 samples per analyte, a median of 603,745 test results per analyte, and 10,298,067 test results in total) performed during patient care in 13 German centers. Test results from children with repeat measurements were discarded, and we estimated the distribution of physiological test results using a validated statistical approach (kosmic).

Results
We report continuous pediatric reference intervals and percentile charts for alanine transaminase, aspartate transaminase, lactate dehydrogenase, alkaline phosphatase, γ-glutamyl-transferase, total protein, albumin, creatinine, urea, sodium, potassium, calcium, chloride, anorganic phosphate, and magnesium. Reference intervals are provided as tables and fractional polynomial functions (i.e., mathematical equations) that can be integrated into laboratory information systems. Additionally, Z-scores and percentiles enable the normalization of test results by age and sex to facilitate their interpretation across age groups.

Conclusions
The provided reference intervals and percentile charts enable precise assessment of laboratory test results in children from birth to adulthood. Our findings highlight the pronounced dynamics in many biochemical analytes in neonates, which require particular consideration in reference intervals to support clinical decision making most effectively.
Updates on liquid biopsy: current trends and future perspectives for clinical application in solid tumors

Published: February 2021

Abstract
Despite advances in screening and therapeutics cancer continues to be one of the major causes of morbidity and mortality worldwide. The molecular profile of tumor is routinely assessed by surgical or bioptic samples, however, genotyping of tissue has inherent limitations: it represents a single snapshot in time and it is subjected to spatial selection bias owing to tumor heterogeneity. Liquid biopsy has emerged as a novel, non-invasive opportunity of detecting and monitoring cancer in several body fluids instead of tumor tissue. Circulating tumor cells (CTCs), circulating tumor DNA (ctDNA), RNA (mRNA and microRNA), microvesicles, including exosomes and tumor “educated platelets” were recently identified as a source of genomic information in cancer patients which could reflect all subclones present in primary and metastatic lesions allowing sequential monitoring of disease evolution. In this review, we summarize the currently available information concerning liquid biopsy in breast cancer, colon cancer, lung cancer and melanoma. These promising issues still need to be standardized and harmonized across laboratories, before fully adopting liquid biopsy approaches into clinical practice.
External quality assessment of M-protein diagnostics: a realistic impression of the accuracy and precision of M-protein quantification
Authors: de Kat Angelino Corrie M. , Jacobs Joannes F.M. 
Published: February 2021

Abstract

Objectives
Studies that investigate the accuracy and precision of M-protein quantification are scarce. These studies are prone to give a biased view, since they are exclusively performed by institutions with international top-expertise on M-protein diagnostics. To obtain a realistic impression of the accuracy and precision of M-protein quantification, we studied results of 73 laboratories participating in the Dutch External Quality Assessment (EQA) program for M-protein diagnostics.

Methods
To measure accuracy, healthy serum was spiked with respectively 1 and 5 g/L human IgG-kappa monoclonal antibody daratumumab. To measure precision, five sera were selected to be repeatedly send to all blinded EQA-participants.

Results
The reported concentrations for the EQA-sample spiked with 5 g/L daratumumab ranged from 2.6 to 8.0 g/L (mean 4.9 g/L, between-laboratory CV = 23%). 98% of the participants detected and correctly characterized the 1 g/L daratumumab band. Both the accuracy (mean 1.7 g/L) and precision (between-laboratory CV = 46%) of this 1 g/L M-protein was poor. In the five EQA-samples that were repeatedly send to the same 73 participating laboratories, between-laboratory precision (mean CV = 25%) was significantly different than the within-laboratory precision (mean CV = 12%). Relatively poor precision was observed in sera with small M-proteins.

Conclusions
The EQA-data reveal a large variation in reported M-protein concentrations between different laboratories. In contrast, a satisfactory within-laboratory precision was observed when the same sample was repeatedly analyzed. The M-protein concentration is correlated with both accuracy and precision. These data indicate that M-protein quantification to monitor patients is appropriate, when subsequent testing is performed within the same laboratory.

Of absent mothers, strong sisters and peculiar daughters: The constructional network of English NPN constructions
Authors: Sommerer Lotte , Baumann Andreas 
Published: February 2021

AbstractThis paper analyzes symmetric NPN constructions (e.g.,day to day, face to face, step by step) qualitatively and quantitatively by examining data from the Corpus of Contemporary American English (Davies, Mark. 2008–. The Corpus of Contemporary American English (COCA): 570 million words, 1990–present.http://corpus.byu.edu/coca/). The constructions’ frequency and productivity, as well as their semantics and extension potential (i.e., modification, complementation) is investigated (e.g., by conducting collostructional analysis). In terms of theoretical modeling, the paper takes a Usage-based, Cognitive Construction Grammar approach (UCCxG) and sketches the constructional network of this constructional family, postulating various constructional templates on different levels of specificity – among others – the existence of the following subtypes [CNsg,timeiafterCNsg,timei]Cx(e.g.,day after day, night after night), [CNsg,measurementibyCNsg,measurementi]Cx(e.g.,inch by inch, step by step) or [CNsg,bodypartitoCNsg,bodyparti]Cx(e.g.,skin to skin, shoulder to shoulder). We show how these templates are vertically and horizontally connected to each other. Ultimately, we argue that in a usage-based model which strives for cognitive plausibility it is not always feasible to postulate the entrenchment of an abstract overarching schema (i.e., a ‘mothernode’) like [CNiP CNi]Cxor even [N P N]Cxhigh up in the network. It is unlikely that speakers abstract such a general schema in a bottom-up acquisition process for this family. Rather, the NPN group is a constructional family characterized by many sister ties and by the absence of mother nodes from which information can be inherited.

Published: February 2021

Abstract
As two-dimensional (2D) materials, graphene and hexagonal-boron nitride (h-BN) are famous for protective coatings, because of their excellent chemical resistance, barrier property, impermeability along with thermal stability, and a large number of these properties are particularly suitable for protective coatings. However, the applications of graphene for metal protection have been limited by galvanic corrosion issues. Also, h-BN nanosheets are also explored as potential materials for corrosion protecting, especially, electrical insulation of h-BN is influential in solving electrochemical reaction and uniquely suitable to be used as an anticorrosion material. Interestingly, graphene doped h-BN exhibit outstanding functionalities in a synergic manner compare to stand-alone 2D materials. This review provides the fundamental summary of preparation methods for graphene and h-BN, meanwhile, the key challenges and future potential of protective coatings are discussed and predicted.
Integrating infection and sepsis management through holistic early warning systems and heuristic approaches: a concept proposal
Authors: Tulli Giorgio , Toccafondi Giulio 
Published: February 2021

Abstract
This is a first attempt to integrate the three pillars of infection management: the infection prevention and control (IPC), and surveillance (IPCS), antimicrobial stewardship (AMS), and rapid identification and management of sepsis (RIMS). The new ‘Sepsis-3’ definition extrapolates the diagnosis of sepsis from our previously slightly naïve concept of a stepwise evolving pattern. In doing so, however, we have placed the transition from infection toward sepsis in the domain of uncertainty and time-dependency. This now demands that clinical judgment be used in the risk stratification of patients with infection, and that pragmatic local solutions be used to prompt clinicians to evaluate formally for sepsis. We feel it is necessary to stimulate the development of a new generation of concepts and models aiming at embracing uncertainty. We see the opportunity for a heuristic approach focusing on the relevant clinical predictors at hand allowing to navigate the uncertainty of infection diagnosis under time constraints. The diverse and situated clinical approaches eventually emerging need to focus on the understanding of infection as the unbalanced interactions of host, pathogen, and environment. In order extend such approach throughout the patient journey we propose a holistic early warning system underpinned by the risk-based categories of hazards and vulnerabilities iteratively fostered by the information gathered by the infection prevention control and surveillance, clinical microbiology, and clinical chemistry services.
Profile of reflexives in Hill Mari
Authors: Burukina Irina 
Published: February 2021

Abstract
The paper provides a detailed examination of reflexive strategies in the Kuznetsovo dialect of Hill Mari (Mari, Uralic) filling in an existing gap in the description of anaphoric elements in Uralic languages. Firstly, I focus on simple lexical reflexives derived from the stem (ə̈)škə̈-. Having examined their morphosyntactic and binding properties, I adopt several typological classifications and approach the Hill Mari data from a cross-linguistic perspective comparing them to anaphors in other Uralic languages. Secondly, I consider other reflexive strategies employed in Uralic languages, such as complex (reduplicative) reflexive pronouns and reflexive detransitivization of a predicate, and I demonstrate that these scenarios are unavailable in the variety of Hill Mari under discussion.
