Parameter Identification of a Strongly Nonlinear Rotor-Bearing System Based on Reconstructed Constant Response Tests
Authors: Zhang Genbei , Zang Chaoping , Friswell Michael I. 
Published: July 2020

Abstract
A strongly nonlinear rotor-bearing system often has multiple solutions under harmonic excitations and jump phenomena. For example, a hardening nonlinearity may include a jump-down in the acceleration process and jump-up in the deceleration process. It is challenging to measure all of these multiple responses and establish an accurate dynamic model from experimental data to predict these phenomena. This paper used a fixed frequency test method to measure all of these multiple responses under harmonic excitations and developed a novel strategy to characterize and identify nonlinearities in a strongly nonlinear rotor-bearing system based on reconstructing constant response tests from fixed frequency test data. The fixed frequency tests are achieved by monotonically increasing the voltage applied to the exciter at a fixed frequency and using the force drop-out phenomenon through the resonance to control the force applied to the structure. This test method could measure multivalued response curves of a strongly nonlinear rotor-bearing system in a nonrotating state. The constant response tests could be reconstructed from these multivalued response curves. The relationship of equivalent stiffness versus displacement can be established, and hence, the nonlinear stiffness is characterized and identified from constant response tests. A rotor-bearing system with a strongly nonlinear support is used to demonstrate the method, and the nonlinear support stiffness parameters are identified and validated in a nonrotating state. The identified nonlinear rotor-bearing model also could predict the jump phenomena in the acceleration or deceleration process. The results demonstrate the feasibility and effectiveness of the approach, and also show the potential for practical applications in engineering.

Published: July 2020

Background: Cocaine may cause persistent changes in the brain, which are more apparent in DA transporter (DAT) and DA receptor availability within the nucleus accumbens (NAc). On the other hand, the DA D3 receptor (D3R) has emerged as a promising pharmacotherapeutic target for substance use disorders. Aims: This study aims to assess the impact of selective D3R antagonism on DAT and D3R after reinstatement of cocaine preference (CPP) induced by an acute session of social defeat stress (SDS) and a cocaine prime in mice after a period of abstinence. Methods: Male mice were conditioned with 25 mg/kg of cocaine for 4 days. After 60 days of extinction training mice were pretreated with the selective D3R antagonist SB-277011A before the re-exposure to a priming dose of cocaine or to a single SDS session. CPP scores were determined and levels of DAT, D3R, phospho Akt (pAkt) and phospho mTOR (pmTOR) were assessed in the NAc shell. Results: An increase in DAT and D3R expression was seen in the NAc after both a cocaine prime- and SDS-induced reinstatement of CPP. Pretreatment with SB-277011A blocked elevated DAT and D3R expression as well as SDS-induced reinstatement. By contrast, the blockade of D3R did not modified the cocaine prime-induced CPP. Changes in DAT and D3R expression do not seem to occur via the canonic pathway involving Akt/mTOR. Conclusions: Our results suggest that the selective D3R antagonist ability to inhibit DAT and D3R up-regulation could represent a possible mechanism for its behavioral effects in cocaine-memories reinstatement induced by social stress.

Published: July 2020

Background Rehabilitation contributes to post-operative success following reverse total shoulder arthroplasty; however, randomised trials comparing the effectiveness of rehabilitation following reverse total shoulder arthroplasty are lacking. This study sought to determine if early, active mobilisation targeting the deltoid and the external rotator muscles, would exhibit greater improvements in post-operative outcomes compared to a delayed and deltoid-focused mobilisation programme. Methods Patients scheduled for reverse total shoulder arthroplasty were randomly assigned to either an early active or delayed active rehabilitation group. Patient-reported outcomes for pain and function were assessed pre-surgery and at 3, 6 and 12 months post-surgery. Objective measures (Constant Score, range of motion, isometric strength) were assessed at 3, 6 and 12 months post-surgery. Results Sixty-one patients (63 shoulders) underwent reverse total shoulder arthroplasty. There were no significant interaction effects or between-group differences for any patient-reported outcomes or objective measures at 3, 6 or 12 months post-surgery. However, significantly better ( p = 0.019) active arm flexion was observed in the early active group at three months post-surgery. Significantly more patients in the early active group reported improvement in patient-reported function that reached minimal clinically important difference from three to six months post-surgery ( p = 0.016). Conclusion Early, active rehabilitation after reverse total shoulder arthroplasty is safe and effective, and may have early clinical benefits over a conservative, delayed mobilisation programme. Level of evidence Therapy, level 1b. Trial registered 15 June 2016 at www.anzctr.org.au (ACTRN12616000779471).

AbstractBackgroundThis systematic review of randomized clinical trials aimed to evaluate the available evidence regarding the efficacy of propolis-based mouthwash on dental plaque and gingival inflammation.MethodsPubMed, Scopus, and Web of Science databases were searched up to November 2019. Clinical trials that evaluated the efficacy of propolis mouthwashes compared with chlorhexidine (CHX) were included. The primary outcomes comprised dental plaque and/or gingival inflammation. Two authors assessed the risk of bias using the Cochrane tool. Due to marked heterogeneity of the available data, studies were assessed qualitatively, and no metaanalysis was performed.ResultsNine clinical trials, comprising 333 subjects, fulfilled the eligibility criteria. Most of the included studies showed high risk of bias. Overall, propolis mouthwashes showed good efficacy on plaque and gingivitis in all of the included studies. Out of the eight studies that reported on plaque index, 5 studies found equal efficacy of propolis and CHX in reducing plaque, two studies found superior efficacy in favor of CHX, while one study found superior efficacy in favor of propolis. Six studies assessed gingival inflammation outcome, four of which reported better results with propolis, while two studies reported comparable results.ConclusionsThe results suggest that propolis-based mouthwashes have potential benefits in reducing plaque and gingival inflammation. However, methodological limitations along with small sample sizes in some of the included studies weaken the strength of the evidence. Therefore, further well-designed clinical trials with large sample sizes and adequate follow-up period are recommended to discern the efficacy of propolis mouthwash on plaque and gingivitis.
The role of patient and public involvement leads in facilitating feedback: “invisible work”

Abstract
Background
Health research in the UK requires patients, those with lived experience and members of the public to be involved in designing and shaping research: many of them have reported that their comments and suggestions are not always acknowledged, and they do not know if their input has been used or is useful. The benefits of feedback from researchers not only create motivation for further involvement but aids learning and development, as well as recording impact. The aims of this study were to improve the feedback experience of Patient and Public Involvement (PPI) contributors. Co-produced feedback processes were designed and implemented in order to change feedback from researchers to PPI contributors in six PPI groups in England.

Methods
An explanatory mixed methods sequential study design was utilised with a comparative questionnaire survey (administered 20 months apart), interviews and a focus group with PPI leads, researchers and PPI contributors. Patient and Public Involvement contributors were involved from initial idea, study design, data analysis through to dissemination.

Results
Co-designed feedback processes were introduced in five of the six PPI groups and there was an overall increase in the frequency of feedback over the period studied. The enablers and barriers to implementing feedback processes were identified, which included the importance of wider institutional level support. PPI leads need to have dedicated time and acknowledge feedback as part of their role. The importance of individual feedback processes designed by, and for each PPI group, rather than a generic one, was also identified as key to successful implementation.

Conclusion
The role of the PPI lead is an important facilitator in improving feedback but can easily be overlooked and has been described as invisible. PPI leads can perform an essential bridging role between researchers and members of the public. This study has shown that PPI feedback processes can be implemented if they are part of embedded PPI with explicit expectations, facilitated by a dedicated PPI lead role with sufficient support and resources. The findings have implications beyond this particular study, particularly for those involved in undertaking and funding health and social care research.
Mapas Sociais: Subsídios para a elaboração do Plano de Gestão territorial e ambiental potiguara
Authors: Gonçalves Alicia Ferreira 
Published: July 2020

Se apresentam resultados da aplicação de uma metodologia baseada no desenho de mapas sociais por indígenas Potiguara do nordeste brasileiro – que configuram subsídios para a elaboração do PGTA. A pesquisa etnográfica foi realizada em oito aldeias entre 2018 e 2019 onde foi realizado um ciclo de oficinas de cartografia social, com trilhas e desenhos dos mapas que refletem as cosmovisões Potiguara. Demandas por saneamento básico, saúde, educação, políticas de geração de renda e ações de proteção ambiental são temáticas desenhadas nos mapas. Assim como, conflitos entre atividades exógenas e atividades tradicionais. O PGTA teria um efeito paradoxal: se realizado e efetivado tem a potência jurídica de conferir autonomia na gestão dos territórios indígenas em consonância com a proteção do ambiente. Se não realizado, se converte em instrumento jurídico de tomada de direitos no atual governo que assume explicitamente o lobby de empreendimentos capitalistas em detrimento dos direitos indígenas assegurados constitucionalmente.

ABSTRACT
Radiation beams precisely directed at a tumor can attenuate the radiation to contiguous tissues. Image-guided radiation therapy using fiducials allows accurate delineation of tumor location. Traditionally, fiducials in the prostate have been placed by urologists or radiation oncologists. With the evolution of endoscopic ultrasound (EUS), fiducials have been successfully placed under the EUS guidance in different organs. In this case series, fiducials were placed in 3 patients with prostate cancer. All patients completed their radiation therapy, and no complications were reported except mild dysuria in one case. EUS-guided fiducial placement is safe and offers a new modality for fiducial placement in the prostate.
The Learner’s Motivation and the Structure of Habituation in Aristotle
Authors: Hampson Margaret 
Published: July 2020

Abstract
Moral virtue is, for Aristotle, a state to which an agent’s motivation is central. For anyone interested in Aristotle’s account of moral development this invites reflection on two questions: how is it that virtuous motivational dispositions are established? And what contribution do the moral learner’s existing motivational states make to the success of her habituation? I argue that views which demand that the learner act with virtuous motives if she is to acquire virtuous dispositions misconstrue the nature and structure of the habituation process, but also obscure Aristotle’s crucial insight that the very practice of virtuous actions affords a certain discovery and can be transformative of an agent’s motivational states. Drawing attention, in Aristotle’s account, to an asymmetry between the agential perspective and the observation of others, I consider what the agential perspective affords the learner, and offer a novel interpretation of the role a learner’s existing motives play in her habituation.
Keeping the Friend in Epicurean Friendship
Authors: Carnes Thomas 
Published: July 2020

Abstract
There seems to be universal agreement among Epicurean scholars that friendship characterized by other-concern is conceptually incompatible with Epicureanism understood as a directly egoistic theory. I reject this view. I argue that once we properly understand the nature of friendship and the Epicurean conception of our final end, we are in a position to demonstrate friendship’s compatibility with, and centrality within, Epicureanism’s direct egoism.
How to begin a sequel?
Authors: Hajdu Péter 
Published: July 2020

AbstractBeginnings of fictional narratives apply various strategies to introduce their readers to the represented world, and even if they select a starting point in the flow of events as definitive, they tend to tell something about how the starting situation has been constituted by earlier events and circumstances. Some literary genres represent fictional worlds so different from the readers’ that a general description of the former is also needed in the beginning. A sequel may seem free of the burden of a descriptive introductory beginning, since readers (if they have read the previous work or works) have sufficient information to be able to cope within medias resbeginning. However, long series of many sequels have to be accessible for new readers as well, therefore they offer introductions for a double audience. The paper analyses several beginnings from Terry Pratchett’s Discworld novels. I show how the early novels use the description of the Discworld as a formal feature to begin the narrative; those descriptions fulfil the double purpose of introducing new readers and entertaining the trained ones by new ways of elaboration and adding some new traits.
Validation of the number of tie vectors in post-processing using the method of frequency in a centric cube
Authors: Kudas Dawid , Wnęk Agnieszka 
Published: July 2020

Abstract
The systems belonging to the European Position Determination System (EUPOS) are obliged to have a sub-service for automatic post-processing (APPS) of static satellite user observations based on observations registered by reference stations. The optimization of the number of tie vectors to reference stations is determined by the authors of APPS algorithms and is a key issue. The study validates the determination of the position of a point based on a smaller number of tie vectors than for the standard solution provided by a sub-service on an example of APPS of the Polish Active Geodetic Network (ASG-EUPOS). It was shown that the reduction of the number of tie vectors by one does not result in a significant deterioration of the accuracy of the obtained coordinates. The other objective of this study is to propose a method for comparing 3D sets. This method is based on 3D figures of assessment and a modification of a method for comparing text sets. The proposed method was validated by comparison with the Spearman correlation coefficient and Mahalanobis distance. The usefulness of the method for similarity and dissimilarity analyses of 3D sets has been demonstrated with an example of comparing the combination of reference vectors with a standard solution of APPS of ASG-EUPOS.
Narratives of the Digital Economy: How Platforms Are Challenging Consumer Law and Hierarchical Organization
Authors: Quarta Alessandra 
Published: July 2020

Abstract
Digital platforms are the essential infrastructures of electronic commerce, online communication, and digital social relationships. They connect two interdependent groups of web users (parties offering goods, services, and digital content; and parties interested in accessing this supply) and enable their transactions. Moreover, they provide additional services such as online payment, collection of reviews and feedback, and internal instant messaging. However, the term “platform” can be misleading, since it seems to denote a virtual space or a technical tool without legal personality. In other words, platforms are masking corporations who hide behind them in order to avoid the legal responsibilities stemming from their status as social institutions. This exploits the dominant theory of the firm as a nexus of contracts and is intended to release the agents involved in the system of production from the restrictions that protect weaker parties in the age of industrial capitalism. Companies who organize production through platforms thus obtain both indirect and direct benefits. In particular, indirect benefits derive from making consumer law more complicated to apply by creating conditions that frustrate the traditional distinction between professionals and consumers. In fact, any user can provide services and sell or share their personal goods (e.g., cars, apartments, clothes, etc.) and other commodities through platforms. However, this does not mean that information asymmetries do not continue to exist, or that weaker parties do not need to be protected. This confusion benefits companies that enable these transactions, since online relationships are not burdened by informative duties. In this case, companies use the platform narrative to facilitate peer-to-peer transactions, where simple, ubiquitous exchanges yield advantages. In addition, platforms provide direct benefits by eliminating the hierarchical organization of their production system in order to adopt the least burdensome and most flexible forms of employment. Companies generally rely on ICT tools to show that the parties offering the service are independent and are not subject to their control. The platform narrative glosses over the labor exploitation issues generally referred to as “uberification”. In addressing the questions outlined in this introduction, the paper will be organized as follows. Part I will discuss how the platform economy is challenging consumer law by short-circuiting its legal grounds in ways that allow companies to benefit. Part II will focus on the direct effects of the platforms’ denial of hierarchical organization: starting from the Italian Supreme Court’s ruling in the Foodora lawsuit, we will explore emergent models for organizing the system of production and their impact on the main categories of private law.

Abstract
Rule-based modeling is an approach that permits constructing reaction networks based on the specification of rules for molecular interactions and transformations. These rules can encompass details such as the interacting sub-molecular domains and the states and binding status of the involved components. Conceptually, fine-grained spatial information such as locations can also be provided. Through “wildcards” representing component states, entire families of molecule complexes sharing certain properties can be specified as patterns. This can significantly simplify the definition of models involving species with multiple components, multiple states, and multiple compartments. The systems biology markup language (SBML) Level 3 Multi Package Version 1 extends the SBML Level 3 Version 1 core with the “type” concept in the Species and Compartment classes. Therefore, reaction rules may contain species that can be patterns and exist in multiple locations. Multiple software tools such as Simmune and BioNetGen support this standard that thus also becomes a medium for exchanging rule-based models. This document provides the specification for Release 2 of Version 1 of the SBML Level 3 Multi package. No design changes have been made to the description of models between Release 1 and Release 2; changes are restricted to the correction of errata and the addition of clarifications.
