Abstract
Objectives
The aims of this study were to (1) investigate the relative time-dependent disruption and bactericidal effects of detergent-type surfactants on single- or dual-species biofilms of root canal isolates and (2) to examine the utility of polygonal graphs for depiction of biofilm disruption and cell killing.

Materials and methods
Single-species biofilms of Streptococcus sanguinis, Enterococcus faecalis, Fusobacterium nucleatum and Porphyromonas gingivalis were grown on nitro-cellulose membranes for 72 h and immersed in Tween®80, cetyltrimethylammoniumbromide (CTAB), and sodium dodecyl sulphate (SDS) for 1-, 5- or 10-min (n = 3 per test). The number of viable and non-viable bacteria “disrupted” from the biofilm and those “remaining-attached” was determined using a viability stain in conjunction with fluorescence microscopy. The data were analysed using non-parametric Kruskal-Wallis test with 5% significance level.

Results
Gram-negative obligate anaerobes were more susceptible to cell removal than gram-positive facultative anaerobes. The majority of cells were disrupted after 1-min of exposure; however, the extent varied according to the agent and species. CTAB and SDS were more effective than Tween 80™ at disrupting biofilms and killing cells but all agents failed to achieve 100% disruption/kill.

Conclusions
Biofilm disruption and cell viability were influenced by the species, the test agent and the duration of exposure. CTAB and SDS were more effective in biofilm disruption than Tween 80™. Graphical depiction of biofilm disruption- and viability-outcomes provides an alternative means of simultaneously visualising and analysing relative efficacy in different domains.

Clinical relevance
Surfactants were not as effective at biofilm disruption as NaOCl but may be added to other non-disruptive antibacterial agents to enhance this property.

Abstract
Purpose
To describe practice patterns and patient outcomes with respect to the use of postoperative systemic therapy (ST) after resection of a solitary breast cancer brain metastasis (BCBM).

Methods
A multi-institutional retrospective review of consecutive patients undergoing resection of a single BCBM without extracranial metastases was performed to describe subtype-specific postoperative outcomes and assess the impact of types of ST on site of recurrence, progression-free survival (PFS), and overall survival (OS).

Results
Forty-four patients were identified. Stratified estimated survival was 15, 24, and 23 months for patients with triple negative, estrogen receptor positive (ER+), and HER2+ BCBMs, respectively. Patients receiving postoperative ST had a longer median PFS (8 versus 4 months, adjusted p-value 0.01) and OS (32 versus 15 months, adjusted p-value 0.21). Nine patients (20%) had extracranial progression, 23 (52%) had intracranial progression, three (8%) had both, and nine (20%) did not experience progression at last follow-up. Multivariate analysis showed that postoperative hormonal therapy was associated with longer OS (HR 0.26; 95% CI 0.08–0.89; p = 0.03) but not PFS (HR 0.35, 95% CI 0.08–1.47, p = 0.15) in ER+ patients. Postoperative HER2-targeted therapy was not associated with longer OS or PFS in HER2+ patients.

Conclusions
Disease progression occurred intracranially more often than extracranially following resection of a solitary BCBM. In ER+ patients, postoperative hormonal therapy was associated with longer OS. Postoperative HER2-targeted therapy did not show survival benefit in HER2+ patients. These results should be validated in larger cohorts.
Temperature Dependence of Thermoelectric Homogeneity of Noble Metal Thermocouples
Authors: Edler Frank , Huang Kai 
Published: January 2020

AbstractThis paper describes the results of low-temperature investigations of the thermoelectric inhomogeneity of conventional standardized noble metal thermocouples (types S and R, Au/Pt and Pt/Pd thermocouples) and of non-standardized Pt/Rh-alloyed thermocouples which have undergone initial annealing at 400 °C for 24 h. The investigations aim to verify the generally accepted practice of using a linear relationship between the inhomogeneity and the measured electromotive force (emf). Immersion profile measurements were carried out in a salt bath at temperatures of about 200 °C, 300 °C, 400 °C, and 500 °C. These temperatures are below the critical temperature range of the selective Rh oxidation of Pt/Rh-alloyed thermocouples. Therefore, the results of the homogeneity investigations should not be influenced by such reversible oxidations effects. Nevertheless, the results of the homogeneity tests at 500 °C showed a deviation from the linearity of the measured inhomogeneities of the thermocouples containing Pt/Rh alloys related to the measurements at 200 °C, 300 °C, and 400 °C. The results obtained with the Au/Pt and Pt/Pd thermocouples confirmed the above-mentioned assumption of the linear relationship between the magnitude of the inhomogeneities and the thermoelectric voltages measured. An additional investigation of a multi-wire thermocouple consisting of non-standardized Pt/Rh alloys (Pt5%Rh, Pt17%Rh, and Pt20%Rh) and a pure platinum thermoelement confirmed the results obtained with the standardized type S and R thermocouples and allowed conclusions to be drawn about re-ordering effects of the Pt/Rh-alloyed thermocouples, which are strongly related to the initial annealing temperature of 400 °C.
Drones Are Flying outside of Segregated Airspace in Poland
Authors: Konert Anna , Kasprzyk Piotr 
Published: January 2020

AbstractPoland was one of the first European countries to adopt a national regulatory framework for the operation of drones. During its first years (2013–2016), the national regulator was more focused on VLOS operations, and BVLOS operations were possible only in segregated airspace. Since 2019, a new law has allowed for certain types of BVLOS operations to be conducted outside of segregated airspace, at very low levels. This paper will analyze how national legislation is dealing with this new technology, focusing on the new law on BVLOS operations. As the national regulation will be replaced in June 2020 by common European rules that have been adopted 2019, this paper also aims to highlight the most important provisions of the EU regulation.
Strain path dependency in incremental sheet-bulk metal forming
Authors: Wernicke S. , Hahn M. , Gerstein G. , Nürnberger F. , Tekkaya A. E. 
Published: January 2020

AbstractIncremental sheet-bulk metal forming (iSBMF) enables the manufacture of functional lightweight components featuring a load-adapted shape with a high material efficiency. The flexibility of the incremental forming process allows for the modification of the strain path through the adjustment of the tool motion while maintaining the final product geometry. These modifications generate both a different strain hardening and damage evolution. In this paper, a numerical and experimental investigation of the different strain paths is carried out to identify their impact on the resulting load capacity of gears. In experiments on the quasistatic load capacity of the gears it is validated that forming of gears with a strain path showing a reduced damage potential leads to a 50% higher load capacity compared to the most unfavorable strain path. Moreover, all investigated load paths present load changes that have to be taken into account in numerical modeling of iSBMF processes. Therefore, a new approach for a material characterization under multiple load changes and high effective plastic strain is tested. Compared to numerical modeling with a characterized monotonically flow curve, this approach decreases the deviation force prediction by around 80% without increasing the calculation time.
Deep Learning for User Interest and Response Prediction in Online Display Advertising

Published: January 2020

AbstractUser interest and behavior modeling is a critical step in online digital advertising. On the one hand, user interests directly impact their response and actions to the displayed advertisement (Ad). On the other hand, user interests can further help determine the probability of an Ad viewer becoming a buying customer. To date, existing methods for Ad click prediction, or click-through rate prediction, mainly consider representing users as a static feature set and train machine learning classifiers to predict clicks. Such approaches do not consider temporal variance and changes in user behaviors, and solely rely on given features for learning. In this paper, we propose two deep learning-based frameworks,$${\hbox {LSTM}}_{\mathrm{cp}}$$LSTMcpand$${\hbox {LSTM}}_{\mathrm{ip}}$$LSTMip, for user click prediction and user interest modeling. Our goal is to accurately predict (1) the probability of a user clicking on an Ad and (2) the probability of a user clicking a specific type of Ad campaign. To achieve the goal, we collect page information displayed to the users as a temporal sequence and use long short-term memory (LSTM) network to learn features that represents user interests as latent features. Experiments and comparisons on real-world data show that, compared to existing static set-based approaches, considering sequences and temporal variance of user requests results in improvements in user Ad response prediction and campaign specific user Ad click prediction.

AbstractThis paper presents a novel mixed reality based navigation system for accurate respiratory liver tumor punctures in radiofrequency ablation (RFA). Our system contains an optical see-through head-mounted display device (OST-HMD), Microsoft HoloLens for perfectly overlaying the virtual information on the patient, and a optical tracking system NDI Polaris for calibrating the surgical utilities in the surgical scene. Compared with traditional navigation method with CT, our system aligns the virtual guidance information and real patient and real-timely updates the view of virtual guidance via a position tracking system. In addition, to alleviate the difficulty during needle placement induced by respiratory motion, we reconstruct the patient-specific respiratory liver motion through statistical motion model to assist doctors precisely puncture liver tumors. The proposed system has been experimentally validated on vivo pigs with an accurate real-time registration approximately 5-mm mean FRE and TRE, which has the potential to be applied in clinical RFA guidance.
Chemical and mechanical control of the invasive shrub Cytisus scoparius in forest clearings in western Washington, USA

Published: January 2020

AbstractWe conducted a large-scale, multiple-year study in harvested areas of Douglas-fir (Pseudotsuga menziesii [Mirbel] Franco) forests in western Washington, examining the effectiveness of control methods on the widespread invasive shrub Scotch broom [Cytisus scoparius (L.) Link]. We tested both chemical and physical control methods, using three different approaches that are management relevant: (1) triclopyr, a POST herbicide, at different times of year and on different-sized plants; (2) cutting (or brushcutting) of mature individuals; and (3) scarification of soil surface to remove seedlings once versus multiple times. We measured initial mortality, seed germination, and percent cover of C. scoparius in plots for 3 yr following treatments. Triclopyr treatment resulted in greater mortality and reduced percent cover compared with all other treatments with the effect persisting for 2 yr after spraying. Further, triclopyr had the same effect on C. scoparius cover and mortality irrespective of time of year applied. Similar to soil scarification, triclopyr treatments resulted in a flush of seedlings, suggesting that removal of conspecific competitors and not soil disturbance per se promotes seed germination. Brushcutting was generally effective in reducing C. scoparius cover in the short term, but effects did not persist as long as triclopyr treatments, in part due to large differences in stump resprouting rates across sites. Soil scarification to remove seedlings, even over multiple years, did not result in reduced C. scoparius cover. Triclopyr is an effective approach for controlling both emerging and established stands of C. scoparius.
Convoy of Scottish Trade by the English Royal Navy on the Eve of the Union of 1707
Authors: Helling Colin George 
Published: January 2020

AbstractThe English Royal Navy's relationship with Scotland during the years preceding the Union of 1707 is usually cast as problematic in scholarly discussion, with the navy viewed as the enforcer of an embargo on Scottish trade with France. This study examines the Scottish use of Royal Naval convoy in the first years of the War of Spanish Succession through to 1707, focusing on the North Sea region. It adds nuance to security issues surrounding the parliamentary union by arguing that convoys to Scotland were more frequent than generally acknowledged, an improvement on the situation in the 1690s, and that when combined with the small Scottish navy, provided coverage that largely met Scottish needs. As a result, in a period of otherwise fierce debate, naval protection for Scotland was relatively uncontroversial. Convoy was therefore an unusual, if belated, success for regal union, and that success meant that Scots were more deeply enmeshed in the English system of maritime security than has been often been credited.
“To Omit the Precise Rule and Strayt Observacion”: The 1572 “Bill Concerning Rites and Ceremonies” and the Campaign for Liturgical Diversity in the Elizabethan Church
Authors: Chou Catherine Lila 
Published: January 2020

AbstractThe focus on the rise and stall of English Presbyterianism has obscured other attempts by politically active puritans to address the problems that bedeviled the Elizabethan church—in particular, how to reconcile a promiscuously international reform movement with the reality of a national church, and the desire for parish-level autonomy with royal supremacy and statutorily mandated uniformity of practice. This article takes as its subject one such attempt, the remarkable “Bill Concerning Rites and Ceremonies” introduced in the 1572 Parliament, which leveraged the episcopal structure of the church to the advantage of the godly, empowering bishops to grant individual priests the right to diverge from the Book of Common Prayer liturgy and to adopt elements of the rituals used by the French and Dutch “stranger churches” then worshipping in London. The bill's emergence at a very specific juncture, after the statutory confirmation of the Thirty-Nine Articles in 1571, illustrates how godly Protestants sought to use newly ratified regulatory powers to their advantage and to establish that only theological, not liturgical, uniformity mattered for a functional and true national church. Moreover, the bill was legally innovative, proposing to use episcopal power in disaggregated ways, thus institutionalizing the exceptions in worship that individual bishops had informally granted to the ministers under their supervision. It offered a remarkable vision of a national church that contained within it ad hoc and multinational liturgies and that was defined not by its adherence to one form of worship but by the supervision of an enlightened bishopric.
“Fire by Night, Cloud by Day”: Exile and Refuge in Postwar London
Authors: Pennybacker Susan 
Published: January 2020

AbstractSusan Pennybacker's presidential plenary to the 2017 North American Conference on British Studies in Denver, Colorado, explores the lives of four of the subjects of her book (in progress) of the same title. It identifies the kinds of archival and ethnographic sources that allow new treatments of the exile, émigré, and expatriate communities of London after the close of World War II and of those who contributed in various ways to the ethos of metropolitan political culture in the “late empire” and Cold War era. The essay focuses on the South African Ruth First, the Indian diplomat Mrs. Vijaya Lakshmi Pandit, the Indian academician Achin Vanaik, and the South Asian Londoner Suresh Grover, a member of the Monitoring Group, a legal assistance and anti-discrimination organization in the capital. It suggests the importance of scholarship that reckons with known and notable activist persons who led and represented many others in their challenges to global politics from a base in the “mammoth crossroads, the secure and unsafe haven that is London.”
Validation and Analysis of Nonlinear System of Centrifugal Compressor using Hot Wire Flow Measurement and Jacobian Matrix
Authors: Hossindokht Seyed Mohammad , Shahsavari Ali , Hesami Amir 
Published: January 2020

ABSTRACTA mathematical method is developed to predict surge and instability inception in a centrifugal compressor map based on Greitzer and Moore model. The method uses phase plane and Jacobian matrix to determine stable and unstable zone of centrifugal compressor and to extract limit cycle in unstable zone. In order to evaluate accuracy of analytical method, a compressor test rig facility is designed and tested in order to be compared with theoretical results. Accurate Honeywell piezoelectric pressure transducers are used to measure time averaged pressure at inlet and outlet ducts of the compressor. In order to record the flow fluctuation precisely, hot wire sensors are installed in entrance and exit of impeller. The results represent instability inception near true stall point but different from measured data. The discrepancy mostly originates from inlet and outlet ducts which causes measure stall point of compressor deviates from true one. An analytical method which is able to predict surge and instability in a compressor is highly significant for instrumentation and controlling of system.
Plastic Dissipation of the Fractional Plasticity using Modified Cam-Clay Yielding Function
Authors: Tai P. , Sun Y. 
Published: January 2020

ABSTRACTSoils usually exhibit state-dependent frictional behaviour that undergoes plastic volumetric deformation. To correctly capture such response under the framework of classical plasticity, a non-associated flow rule using additional plastic potential is inevitably needed. Recently, a novel fractional plasticity (FP) without using plastic potential has been developed, and successfully applied in modelling the state-dependent nonassociated behaviour of soils. However, the energy dissipation characteristics of FP has not been probed in depth. This note examines the plastic dissipation behaviour of FP, when modelling the constitutive behaviour of soils. It is found that the plastic dissipation of FP increases continuously with the shear strain. However, the rate of plastic dissipation depends on the initial material state in relation to the critical state line.
Identifying key players in bipartite networks
Authors: Duxbury Scott W. 
Published: January 2020

AbstractMeasures of bipartite network structure have recently gained attention from network scholars. However, there is currently no measure for identifying key players in two-mode networks. This article proposes measures for identifying key players in bipartite networks. It focuses on two measures: fragmentation and cohesion centrality. It extends the centrality measures to bipartite networks by considering (1) cohesion and fragmentation centrality within a one-mode projection, (2) cross-modal cohesion and fragmentation centrality, where a node in one mode is influential in the one-mode projection of the other mode, and (3) cohesion and fragmentation centrality across the entire bipartite structure. Empirical examples are provided for the Southern Women’s data and on the Ndrangheta mafia data.
“Fighting Spirit”: World War I and the YMCA's Allied Boxing Program
Authors: Park Adam 
Published: January 2020

ABSTRACTThis article highlights the U.S. Armed Forces’ appointment of the YMCA to train American soldiers in boxing during World War I and so contributes to scholarly research on religion and war as well as religion and sports. As the YMCA taught the fistic art to white regiments in stateside military camps and to the American Expeditionary Forces on the Western Front, I argue that World War I was a watershed moment for both Muscular Christianity and boxing. Religious, political, and military leaders announced boxing to be ideal for the close-proximity encounters in the trenches, and they championed the YMCA as being best equipped to turn newly enlisted recruits into hardened trench-pugs. To the YMCA-military, the practical benefits of boxing were that soldiers would not just be “good with their hands” but also have a good manly character, a “fighting spirit.” In the establishment of a new world order, boxing thereby became a bellicose technique for unmaking evil others and a Christian method for remaking “overcivilized” white men. Immediately after the war—because of the Y—the sport of boxing, previously believed unscrupulous, was redeemed. Protestant Christians and a larger public recast boxing as less an activity for the morally corrupt and the criminal underworld and more an enlightened pursuit in the realization of an authentic, God-given human nature. Legalized, mainstreamed, and backed by antimodern logic, Christian theology, and white fears of racial devolution, boxing was for “character” more than crime.
Daʿwain the Neighborhood: Female-Authored Muslim Students Association Publications, 1963–1980
Authors: Howe Justine 
Published: January 2020

AbstractFounded in 1963 at the University of Illinois Urbana-Champaign, the Muslim Students Association of the United States and Canada (MSA) expanded to 116 local chapters by 1968, with members representing more than forty countries. During the Cold War, the MSA embraced the project ofdaʿwa, or renewing and correcting other Muslims’ devotional practice, and improving the public image of Islam. Extant scholarship on the MSA portrays the organization as ambivalent, if not antagonistic, toward U.S. society during the Cold War because it was deeply enmeshed in the political and religious ideologies associated with the global Islamic Revival. This article offers a different view by examining female-authored writings published under the auspices of the MSA Women's Committee between 1963 and 1980. Aspirational in scope and pedagogical in approach, MSA women's literature shifts conceptions of the MSA's political and religious priorities during this period, from one of detachment to one of selective engagement with American culture. This article makes three main interventions. First, it demonstrates that a focus on the publications of MSA female members yields a more robust understanding of how this important group of American Muslims envisioneddaʿwaas a local and global project of religious revival during the Cold War. Second, it shows that, to achieve their revivalist aims, female MSA members identified points of affinity with certain religious non-Muslim Americans, namely, upwardly mobile Christians and Jews. For these authors, the ground on which they found affinity with families of other faiths was not theology or Abrahamic lineage but, rather, a shared gendered and classed vision of raising devout children to meet the unique threats posed by modernity. Finally, this article examines how female MSA authors conceived of the patriarchally organized yet maternally driven nuclear family as essential for reinvigorating Muslim practice.
