Exploration on molecular dynamics simulation methods of microscopic wetting process for coal dust
Authors: Zhang Qi , Chen Xinyi , Wang Hetang , Xu Chaohang 
Published: March 2021

AbstractWet dust removal is one of the main technical measures in coal dust control, and coal dust wetting is the key factor to determine the effect of wet dust removal. In order to explore the micro-wetting process of coal dust, this paper uses molecular dynamics simulation to study the micro-wetting process of coal dust in different simulation conditions. The molecular dynamics simulation was carried out under different ensemble, thermodynamic states as well as relaxation pretreatment methods, then the H2O molecular layer and coal dust molecular layer in each simulation were quantitatively analyzed by relative concentration. The research results show that a method for establishing molecular model of lignite is proposed and the 2D periodic surface structure is more reasonable. The surface system of coal-H2O molecule is established by NVT aeration method, where the simulation result is close to the actual coal dust wetting process. The simulation effect of medium and large coal dust-H2O molecular system is better than that of small coal dust-H2O molecular system. This study provides a new solution for changing the empirical method of molecular dynamics simulation of coal system wetting and oversimplification of coal system.

Abstract
Single-cell mass cytometry (SCMC) combines features of traditional flow cytometry (i.e., fluorescence-activated cell sorting) with mass spectrometry, making it possible to measure several parameters at the single-cell level for a complex analysis of biological regulatory mechanisms. In this study, we optimized SCMC to analyze hemocytes of the Drosophila innate immune system. We used metal-conjugated antibodies (against cell surface antigens H2, H3, H18, L1, L4, and P1, and intracellular antigens 3A5 and L2) and anti-IgM (against cell surface antigen L6) to detect the levels of antigens, while anti-GFP was used to detect crystal cells in the immune-induced samples. We investigated the antigen expression profile of single cells and hemocyte populations in naive states, in immune-induced states, in tumorous mutants bearing a driver mutation in the Drosophila homologue of Janus kinase (hopTum) and carrying a deficiency of the tumor suppressor gene lethal(3)malignant blood neoplasm-1 [l(3)mbn1], as well as in stem cell maintenance-defective hdcΔ84 mutant larvae. Multidimensional analysis enabled the discrimination of the functionally different major hemocyte subsets for lamellocytes, plasmatocytes, and crystal cells, and delineated the unique immunophenotype of Drosophila mutants. We have identified subpopulations of L2+/P1+ and L2+/L4+/P1+ transitional phenotype cells in the tumorous strains l(3)mbn1 and hopTum, respectively, and a subpopulation of L4+/P1+ cells upon immune induction. Our results demonstrated for the first time that SCMC, combined with multidimensional bioinformatic analysis, represents a versatile and powerful tool to deeply analyze the regulation of cell-mediated immunity of Drosophila.
Applying Risk Management Concepts from CRM and the Outdoor Recreation Industry to Academic Archaeology Projects
Authors: White William A. 
Published: March 2021

ABSTRACTField safety is being taken more seriously across the cultural resource management (CRM) industry as CRM companies seek to be in compliance with their clients’ health and safety programs and to keep employees safe. Many universities also have organizational health and safety programs designed to protect students and employees, but academic archaeology is routinely conducted without adequate risk management planning. Risk management will be a workplace concern for aspiring archaeologists after graduating from college, which is why it is important for academic archaeology to meet industry standards. Archaeology can learn a great deal about fieldwork risk management from the outdoor recreation industry, which emphasizes building leadership skills rather than following proscribed rules and regulations to mitigate the myriad hazards in the field. This article provides some suggestions that academic archaeologists can use to apply risk management concepts from CRM and the outdoor recreation industry to academic projects in order to comply with university requirements and the Occupational Safety and Health Administration (OSHA), as well as to teach students how to be safe in the field.
Digital Data and Data Literacy in Archaeology Now and in the New Decade
Authors: Kansa Eric , Kansa Sarah Whitcher 
Published: March 2021

OVERVIEWDigital data play an increasingly important role in how we understand the present and the past. The challenges inherent in understanding and using digital data are as intellectually demanding as any other archaeological research endeavor. For these reasons, data management cannot be regarded as a simple compliance or technical issue. For data to be meaningfully preserved and used in intellectually rigorous ways, they need to be integrated fully into all aspects of archaeological practice, including ethics, teaching, and publishing. In this review, we highlight some of the significant and multifaceted challenges involved in managing data, including documentation, training, methodology, data modeling, trust, and ethical concerns. We then focus on the importance of building data literacy broadly among archaeologists so that we can manage and communicate the data our discipline creates. This involves more than learning to use a new tool or finding a data manager for one's excavation or survey. Long-term, responsible stewardship of data requires understanding the workflows and human roles in data management. Putting effort now into thoughtful data management and broad data-literacy training means we will be able to make the most of the “bigger” data that archaeologists now produce. An important aspect of this reorientation will be to look beyond the boundaries of our own research projects and information systems. Future research, teaching, and public engagement needs will also compel us to explore how our data articulates with wider contexts—within and beyond our discipline.
Nietzsche: Metaphysician
Authors: REMHOF JUSTIN 
Published: March 2021

AbstractPerhaps the most fundamental disagreement concerning Nietzsche's view of metaphysics is that some commentators believe Nietzsche has a positive, systematic metaphysical project, and others deny this. Those who deny it hold that Nietzsche believes metaphysics has a special problem, that is, a distinctively problematic feature that distinguishes metaphysics from other areas of philosophy. In this paper, I investigate important features of Nietzsche's metametaphysics in order to argue that Nietzsche does not, in fact, think metaphysics has a special problem. The result is that, against a long-standing view held in the literature, we should be reading Nietzsche as a metaphysician.

ABSTRACTBackground:The effectiveness of mechanical thrombectomy (MT) in elderly stroke patients remains debated. We aimed to describe outcomes and their predictors in a cohort of patients aged ≥ 85 years treated with MT.Methods:Data from consecutive patients aged ≥ 85 years undergoing MT at two stroke centers between January 2016 and November 2019 were reviewed. Admission National Institutes of Health Stroke Scale (NIHSS), pre-stroke, and 3-month modified Rankin scale (mRS) were collected. Successful recanalization was defined as modified thrombolysis in cerebral ischemia score ≥ 2b. Good outcome was defined as mRS 0–3 or equal to pre-stroke mRS at 3 months.Results:Of 151 included patients, successful recanalization was achieved in 74.2%. At 3 months, 44.7% of patients had a good outcome and 39% had died. Any intracranial hemorrhage (ICH) and symptomatic ICH occurred in 20.3% and 3.6%, respectively. Logistic regression analysis identiﬁed lower pre-stroke mRS score (adjusted odds ratio [aOR], 0.52; 95% CI, 0.36–0.76), lower admission NIHSS score (aOR, 0.90; 95% CI, 0.83–0.97), successful recanalization (aOR, 3.65; 95% CI, 1.32–10.09), and absence of ICH on follow-up imaging (aOR, 0.42; 95% CI, 0.08–0.75), to be independent predictors of good outcome. Patients with successful recanalization had a higher proportion of good outcome (45.3% vs 34.3%, p = 0.013) and lower mortality at 3 months (35.8% vs 48.6%, p = 0.006) compared to patients with unsuccessful recanalization.Conclusions:Among patients aged ≥ 85 years, successful recanalization with MT is relatively common and associated with better 3-month outcome and lower mortality than failed recanalization. Attempting to achieve recanalization in elderly patients using MT appears reasonable.
More than a century of direct glacier mass-balance observations on Claridenfirn, Switzerland

Published: March 2021

AbstractGlacier mass-balance observations at seasonal resolution have been performed since 1914 at two sites on Claridenfirn, Switzerland. The measurements are the longest uninterrupted records of glacier mass balance worldwide. Here, we provide a complete re-analysis of the 106-year series (1914–2020), focusing on both point and glacier-wide mass balance. The approaches to evaluate and homogenize the direct observations are described in detail. Based on conservative assumptions, average uncertainties of$\pm$0.25 m w.e. are estimated for glacier-wide mass balances at the annual scale. It is demonstrated that long-term variations in mass balance are clearly driven by melting, whereas decadal changes in accumulation are uncorrelated with mass balance and can only be relevant in short periods. Mass change of Claridenfirn is impacted by dry calving at a frontal ice cliff. Considerations of ice volume flux at a cross-profile reveal long-term variations in frontal ice loss accounting for$\sim$9% of total annual ablation on average. The effect of changes in frontal ablation mostly explains$\lt$10% of the mass-balance difference relative to the period 1960–1990, but accounts for$\sim$20% in 2010–2020. Glacier mass changes are discussed in the context of observations throughout the European Alps indicating that Claridenfirn is regionally representative.
The traceback method in child language acquisition research: identifying patterns in early speech
Authors: HARTMANN STEFAN , KOCH NIKOLAS , QUICK ANTJE ENDESFELDER 
Published: March 2021

abstractThis paper discusses the traceback method, which has been the basis of some influential papers on first language acquisition. The method sets out to demonstrate that many or even all utterances in a test corpus (usually the last two sessions of recording) can be accounted for with the help of recurrent fixed strings (likeWhat’s that?) or frame-and-slot patterns (like [What’sX?]) that can also be identified in the remaining dataset (i.e., the previous sessions of recording). This is taken as evidence that language learning is much more item-based than previously assumed. In the present paper we sketch the development of the method over the last two decades, and discuss its relation to usage-based theory, as well as the cognitive plausibility of its components, and we highlight both its potential and its limitations.
Turkey’s queer times: epistemic challenges
Authors: Savcı Evren 
Published: March 2021

AbstractThis article suggests that Turkey’s queer times are co-constitutive with Jasbir Puar’s queer times of homonationalism. If the queer times of homonationalism correspond to a folding of some queers into life and respectability at the cost of rising Islamophobia in the “West,” Turkey’s queer times witnessed the increasing marginalization and “queering” of variously respectable subjects in the name of Islam and strong LGBT organizing against such marginalization. It discusses the epistemic challenges of studying Turkey’s queer times that stem from a theoretical suspicion that “queer” operates as a tool of colonial modernity when it spreads to the “non-West,” a suspicion that is due both to a perception of Islam as a target and victim of Western neocolonialism and to an ahistorical and rigidly discursive understanding of language. In turn, scholarship on Turkey’s queer times has the potential to truly transnationalize queer studies, both getting us out of the binaries of global–local, colonial–authentic, and West–East and reminding scholars that hegemonies are scattered.
Out on the fringe: Wales and the history of science
Authors: Morus Iwan Rhys 
Published: March 2021

Imagine a scene sometime in the 1750s in the depths of west Wales. This was wild country. Even a century later, George Borrow called it a ‘mountainous wilderness … a waste of russet-coloured hills, with here and there a black craggy summit’. Through this desolation rides the Reverend William Williams. As he rode, he read – and the book in his saddlebags on this occasion was William Derham'sAstro-Theology, first published some twenty years earlier. Williams was a leading figure in the Methodist revolution that had been sweeping through Wales for the past two decades. Disenchanted with an Anglican Church that seemed increasingly disconnected – culturally and linguistically – from their everyday lives, and attracted by powerful and charismatic preachers like Williams himself, men and women across Wales turned to Methodism. They organized themselves into local groups worshipping in meeting houses rather than in their parish churches. Leaders like Williams usually had a number of such groups under their care, and spent much of their time on horseback, travelling between widely scattered communities to minister to their congregations. That Williams read in the saddle is well known. As shall become clear, he had certainly read Derham's book as well. It is not too much of an imaginative leap, therefore, to picture him reading about God's design of the cosmos as he rode through the Welsh hills – and it is a good image with which to begin a discussion about Wales, science and European peripheries.
New species ofMicrosclerodermaandAmphibleptula(Demospongiae, Tetractinellida, Scleritodermidae) from two contrasting marine environments

Published: March 2021

AbstractWe record for the first time a nominal species of the genusMicrosclerodermain the Western Atlantic, and the first record of the genusAmphibleptulain Mexico. Two new species of ‘lithistid’ Tetractinellida are described:Microscleroderma mexicasp. nov. from crevices of two reefs in Veracruz, Mexico, andAmphibleptula aaktunsp. nov. from the anchialine cave El Aerolito, Cozumel Island, Mexico.Microscleroderma mexicasp. nov. is characterized by its tubular and cup-shaped to wavy laminar habitus, hirsute surface and two size categories of oxea diactines.Amphibleptula aaktunsp. nov. is characterized by its ficiform or lobular habitus with an exhalant area at the flat top of the body, divided into numerous vertical septa-like structures; its desmas have thinner epirhabds, and thinner oxea than those ofAmphibleptula madrepora. This is the second species ofAmphibleptulathat has been described; hence, we propose the redefinition of the genus. Both species described have a shallow distribution (≤21 m depth); they are differentiated from each other by the disjunction between their habitats as well as by their morphology.
Associations between individual antipsychotics and the risk of arrests and convictions of violent and other crime: a nationwide within-individual study of 74 925 persons

AbstractBackgroundIndividuals diagnosed with psychiatric disorders who are prescribed antipsychotics have lower rates of violence and crime but the differential effects of specific antipsychotics are not known. We investigated associations between 10 specific antipsychotic medications and subsequent risks for a range of criminal outcomes.MethodsWe identified 74 925 individuals who were ever prescribed antipsychotics between 2006 and 2013 using nationwide Swedish registries. We tested for five specific first-generation antipsychotics (levomepromazine, perphenazine, haloperidol, flupentixol, and zuclopenthixol) and five second-generation antipsychotics (clozapine, olanzapine, quetiapine, risperidone, and aripiprazole). The outcomes included violent, drug-related, and any criminal arrests and convictions. We conducted within-individual analyses using fixed-effects Poisson regression models that compared rates of outcomes between periods when each individual was either on or off medication to account for time-stable unmeasured confounders. All models were adjusted for age and concurrent mood stabilizer medications.ResultsThe relative risks of all crime outcomes were substantially reduced [range of adjusted rate ratios (aRRs): 0.50–0.67] during periods when the patients were prescribed antipsychotics v. periods when they were not. We found that clozapine (aRRs: 0.28–0.44), olanzapine (aRRs: 0.46–0.72), and risperidone (aRRs: 0.53–0.64) were associated with lower arrest and conviction risks than other antipsychotics, including quetiapine (aRRs: 0.68–0.84) and haloperidol (aRRs: 0.67–0.77). Long-acting injectables as a combined medication class were associated with lower risks of the outcomes but only risperidone was associated with lower risks of all six outcomes (aRRs: 0.33–0.69).ConclusionsThere is heterogeneity in the associations between specific antipsychotics and subsequent arrests and convictions for any drug-related and violent crimes.
NEITHER ABSOLUTISM NOR NEGOTIATION: SPANISH EMPIRE BUILDING AND POLITICAL ECONOMY IN THE 18THCENTURY CARIBBEAN
Authors: Bohorquez J. 
Published: March 2021

ABSTRACTThis paper revisits the political economy during Spanish rule in America by reappraising the allegedly positive impact that intra-imperial transfers (situados) had on the Caribbean economy. It raises concerns concerning categories such as bargaining and absolutism and their accuracy in accounting for the nature of Spanish imperial rule. Three main findings are reported. Firstly, it seems inaccurate to hold that all remittances were injected into the economy with positive effects. Liquidity apparently provoked a real estate bubble. Secondly, the local market was not necessarily sensitive to the arrival of bullion. Finally, jurisdictional fragmentation allowed the king to issue debt in a disorderly fashion and with no constraints, and local officials and groups of interests to behave as free riders.
Escaping theTrap: Losing the Northern Cities Shift in Real Time
Authors: Thiel Anja , Dinkin Aaron J. 
Published: March 2021

AbstractWe examine the loss of the Northern Cities Shift raising oftrapin Ogdensburg, a small city in rural northern New York. Although data from 2008 showed robusttrap-raising among young people in Ogdensburg, in data collected in 2016 no speakers clear the 700-Hz threshold for NCS participation in F1 oftrap—a seemingly very rapid real-time change. We find apparent-time change in style-shifting: although older people raisetrapmore in wordlist reading than in spontaneous speech, younger people do the opposite. We infer that increasing negative evaluation of the feature led Ogdensburg speakers to collectively abandon raisingtrapbetween 2008 and 2016. This indicates a role for communal change in the transition of a dialect feature from an indicator to a marker.
Extracting possessions from text: Experiments and error analysis
Authors: Chinnappa Dhivya , Blanco Eduardo 
Published: March 2021

AbstractThis paper presents a corpus and experiments to mine possession relations from text. Specifically, we target alienable and control possessions and assign temporal anchors indicating when a possession relation holds between the possessor and possessee. We work with intra-sentential possessor and possessees that satisfy lexical and syntactic constraints. We experiment with traditional classifiers and neural networks to automate the task. In addition, we analyze the factors that help to determine possession existence and possession type and common errors made by the best performing classifiers. Experimental results show that determining possession existence relies on the entire sentence, whereas determining possession type primarily relies on the verb, possessor and possessee.
Regulators and environmental groups: better together or apart?
Authors: Espinola-Arredondo Ana , Stathopoulou Eleni , Munoz-Garcia Felix 
Published: March 2021

AbstractThis paper examines green alliances between environmental groups (EGs) and polluting firms, which have become more common in the last decades, and analyzes how they affect policy design. We first show that the activities of regulators and EGs are strategic substitutes, giving rise to free-riding incentives on both agents. Nonetheless, the presence of the EG yields smaller welfare benefits when firms are subject to regulation than when they are not. In addition, the introduction of environmental policy yields large welfare gains when the EG is absent but small benefits when the EG is already present.
Evaluation of the surface dose for total body irradiation (TBI) technique with parallel-opposed anterior posterior geometry

Published: March 2021

AbstractAim:Total body irradiation (TBI) is an external radiotherapy technique in which the whole body including the superficial regions is required to receive the therapeutic dose. The purpose of this study is to evaluate the received surface dose during TBI technique.Methods and materials:The anterior/posterior (AP/PA) TBI was implemented with 18-MV photon beam at 312-cm treatment distance for human-like phantom. The GAFCHROMIC-EBT3 films were used for superficial dose measurements.Results and discussion:The percentage of surface-absorbed dose relative to the prescription point for 8 points of measurements was between 102·78–121·48% and 104·51–127·43% at 5 and 10 mm depth, respectively. In the chest wall region due to the presence of lung blocks, the absorbed dose was below the acceptable level, so an electron boost was required to increase the chest wall absorbed dose.Conclusions:According to the results, the implemented technique was able to deliver sufficient dose to the shallow surface of phantom’s body.
