description: Inflammatory signaling pathways orchestrate the cellular response to infection and injury. These pathways are known to be modulated by compounds that alkylate cysteinyl thiols. One class of phytochemicals with strong thiol alkylating activity is the chalcones. In this study we tested fourteen chalcone derivatives, α-X-substituted 2’,3,4,4’-tetramethoxychalcones (α-X-TMCs, X = H, F, Cl, Br, I, CN, Me, p-NO2-C6H4, Ph, p-OMe-C6H4, NO2, CF3, COOEt, COOH), for their ability to modulate inflammatory responses, as monitored by their influence on heme oxygenase-1 (HO-1) activity, inducible nitric oxide synthase (iNOS) activity, and cytokine expression levels. We confirmed that α-X-TMCs activate Nrf2 transcriptional activity and inhibit NF-κB transcriptional activity. For most α-X-TMCs, anti-inflammatory activity was positively correlated with thiol alkylating activity, i.e. stronger electrophiles (X = CF3, Br and Cl) being more potent. Notably, this correlation did not hold true for the strongest electrophiles (X = CN and NO2) which were found to be ineffective as anti-inflammatory compounds. These results emphasize the idea that chemical fine-tuning of electrophilicity is needed to achieve and optimize desired therapeutic effects.

description: We report detailed 17O, 139La, and 63Cu Nuclear Magnetic Resonance (NMR) and Nuclear Quadrupole Resonance (NQR) measurements in a stripe ordered La1.875Ba0.125CuO4 single crystal and in oriented powder samples of La1.8-xEu0.2SrxCuO4. We observe a partial wipeout of the 17O NMR intensity and a simultaneous drop of the 17O electric field gradient (EFG) at low temperatures where the spin stripe order sets in. In contrast, the 63Cu intensity is completely wiped out at the same temperature. The drop of the 17O quadrupole frequency is compatible with a charge stripe order. The 17O spin lattice relaxation rate shows a peak similar to that of the 139La, which is of magnetic origin. This peak is doping dependent and is maximal at x ~ 1/8.

description: Objective: This in vitro study aims to investigate the antimicrobial effect of extracts from Commiphora gileadensis (C. gileadensis) on one and three weeks old oral anaerobic multispecies biofilms and to compare them to 2% chlorhexidine (CHX). Material and Methods: Hydroxyapatite discs were coated with type I collagen and immersed in Brain Heart Infusion broth infused with an oral subgingival plaque obtained from two donors. The discs were then incubated under anaerobic conditions for one or three weeks. After biofilm growth, the discs were exposed to one or three minutes for the following solutions: 1 - C. gileadensis 1mg/ml water, 2 - C. gileadensis 0.1mg/ml water, 3 - C. gileadensis 1mg/ml 0.5% DMSO, 4 - C. gileadensis 0.1mg/ml 0.5% DMSO, 5 - water, 6 - 2%CHX and 7 - 0.5%DMSO. After the exposures, all discs were stained with a viability stain and scanned under a confocal laser scanning microscope. The percentage of dead bacteria was calculated using Imaris software. The data were submitted to Univariate analysis of variance and Tukey statistical tests (P < 0.05). Results: C. gileadensis 1mg/ml water killed significantly more bacteria than all other groups (P < 0.05). 2%CHX and other groups of C. gileadensis killed bacteria without a significant difference among themselves (P > 0.05). In 0.5%DMSO and water groups only a few bacteria were killed. Conclusion: Commiphora gileadensis extract 1mg/ml in water killed significantly more bacteria in oral anaerobic multispecies biofilm than 2% CHX.

description: Let $\bk=(k_1,...,k_n)$ be a sequence of $n$ integers. For an increasing monotone graph property $\mP$ we say that a base graph $G=([n],E)$ is \emph{$\bk$-resilient} with respect to $\mP$ if for every subgraph $H\subseteq G$ such that $d_H(i)\leq k_i$ for every $1\leq i\leq n$ the graph $G-H$ possesses $\mP$. This notion naturally extends the idea of the \emph{local resilience} of graphs recently initiated by Sudakov and Vu. In this paper we study the $\bk$-resilience of a typical graph from $\GNP$ with respect to the Hamiltonicity property where we let $p$ range over all values for which the base graph is expected to be Hamiltonian. In particular, we prove that for every $ε>0$ and $p\geq\frac{\ln n+\ln\ln n +ω(1)}{n}$ if a graph is sampled from $\GNP$ then with high probability removing from each vertex of "small" degree all incident edges but two and from any other vertex at most a $(\frac{1}{3}-ε)$-fraction of the incident edges will result in a Hamiltonian graph. Considering this generalized approach to the notion of resilience allows to establish several corollaries which improve on the best known bounds of Hamiltonicity related questions. It implies that for every positive $ε>0$ and large enough values of $K$, if $p>\frac{K\ln n}{n}$ then with high probability the local resilience of $\GNP$ with respect to being Hamiltonian is at least $(1-ε)np/3$, improving on the previous bound for this range of $p$. Another implication is a result on optimal packing of edge disjoint Hamilton cycles in a random graph. We prove that if $p\leq\frac{1.02\ln n}{n}$ then with high probability a graph $G$ sampled from $\GNP$ contains $\lfloor\frac{δ(G)}{2}\rfloor$ edge disjoint Hamilton cycles, extending the previous range of $p$ for which this was known to hold.

description: Quantum mechanics is a nonlocal theory, but not as nonlocal as the no-signalling principle allows. However, there exist quantum correlations that exhibit maximal nonlocality: they are as nonlocal as any non-signalling correlations and thus have a local content, quantified by the fraction $p_L$ of events admitting a local description, equal to zero. Exploiting the link between the Kochen-Specker and Bell's theorems, we derive, from every Kochen-Specker proof, Bell inequalities maximally violated by quantum correlations. We then show that these Bell inequalities lead to experimental bounds on the local content of quantum correlations which are significantly better than those based on other constructions. We perform the experimental demonstration of a Bell test originating from the Peres-Mermin Kochen-Specker proof, providing an upper bound on the local content $p_L\lesssim 0.22$.

description: Genotype-phenotype association studies often combine phenotype data from multiple studies to increase statistical power. Harmonization of the data usually requires substantial effort due to heterogeneity in phenotype definitions, study design, data collection procedures, and data-set organization. Here we describe a centralized system for phenotype harmonization that includes input from phenotype domain and study experts, quality control, documentation, reproducible results, and data-sharing mechanisms. This system was developed for the National Heart, Lung, and Blood Institute’s Trans-Omics for Precision Medicine (TOPMed) program, which is generating genomic and other -omics data for more than 80 studies with extensive phenotype data. To date, 63 phenotypes have been harmonized across thousands of participants (recruited in 1948–2012) from up to 17 studies per phenotype. Here we discuss challenges in this undertaking and how they were addressed. The harmonized phenotype data and associated documentation have been submitted to National Institutes of Health data repositories for controlled access by the scientific community. We also provide materials to facilitate future harmonization efforts by the community, which include 1) the software code used to generate the 63 harmonized phenotypes, enabling others to reproduce, modify, or extend these harmonizations to additional studies, and 2) the results of labeling thousands of phenotype variables with controlled vocabulary terms.

description: Neste texto apresenta-se uma reflexão crítica sobre práticas pedagógicas de dois professores responsáveis pela lecionação conjunta da unidade curricular de Língua Portuguesa e Tecnologias de Informação e Comunicação, da licenciatura em Educação Básica. A reflexão assenta em resultados recolhidos através da observação participante durante aulas com duas turmas, através das reflexões individuais finais escritas pela totalidade dos estudantes das duas turmas, através de três trabalhos produzidos a pares por alguns estudantes e, por fim, através de entrevista com estes estudantes. Com o conjunto de atividades em análise, pretendia-se desenvolver a competência de escrita narrativa e de produção de um texto multimédia. Constatou-se, porém, que as novas aprendizagens mais relevantes se verificaram noutras áreas: na produção do guião, ferramenta transformadora do texto escrito em texto multimédia, e no registo da expressão oral planificada das crianças que colaboraram na criação do PhotoStory.

description: As tecnologias móveis invadiram a vida do cidadão do século XXI quer através dos smartphones quer através dos tablets ou computadores. Atualmente, os smartphones são considerados computadores em pequeno tamanho. Se os pro-fessores e educadores reconhecem as potencialidades dos computadores para o ensino, também os telemóveis poderão ser um suporte importante nesse processo com a vantagem acrescida de estarem sempre presentes. Esta investigação é uma parte de um projeto galardoado como Projeto de Inovação Pedagógica no Ensino à Distância e foi aplicado durante várias aulas a potenciais professores do ensino básico. Aqui, procuramos perceber a influência da integração do smartphone nas dinâmicas da sala de aula e destacar alguns benefícios que possam contribuir para uma reflexão sobre esta temática. Os resultados do estudo apontam como principais benefícios o empenho, o envolvimento e a motivação dos participantes que são incrementos fundamentais para o processo de ensino e aprendizagem.

description: A presente pesquisa tem como objetivo principal uma proposta de estímulo à criatividade de jovens por meio da robótica educacional. Serão apresentados, os resultados de três oficinas executadas nas dependências de um laboratório de inovação de uma instituição de ensino superior com jovens entre 13 e 16 anos. Os participantes foram desafiados a resolver determinadas atividades relacionadas com robótica educacional utilizando como ferramentas Scratch, S4A e Arduino, tendo como tema proposto a educação no trânsito. As categorias de análise elencadas na presente pesquisa foram: uso de soluções incomuns para resolução de problemas, nível de motivação intrínseca e uso de pensamento organizado e procedimental. Mesmo sendo possível identificar a ocorrência de todas as categorias de análise escolhidas para o desenvolvimento da pesquisa, a categoria de menor aceitação foi o uso de soluções incomuns para a resolução de problemas. Em futuras pesquisas, espera-se amadurecer o modelo apresentado para constituir uma nova metodologia de aplicação de robótica educacional para estímulo da criatividade de jovens.

description: We study first-passage percolation in two dimensions, using measures mu on passage times with b:=inf supp(mu) >0 and mu({b})=p \geq p_c, the threshold for oriented percolation. We first show that for each such mu, the boundary of the limit shape for mu is differentiable at the endpoints of flat edges in the so-called percolation cone. We then conclude that the limit shape must be non-polygonal for all of these measures. Furthermore, the associated Richardson-type growth model admits infinite coexistence and if mu is not purely atomic the graph of infection has infinitely many ends. We go on to show that lower bounds for fluctuations of the passage time given by Newman-Piza extend to these measures. We establish a lower bound for the variance of the passage time to distance n of order log n in any direction outside the percolation cone under a condition of finite exponential moments for mu. This result confirms a prediction of Newman-Piza and Zhang. Under the assumption of finite radius of curvature for the limit shape in these directions, we obtain a power-law lower bound for the variance and an inequality between the exponents chi and xi.
description: 32 pages, 3 figures. This is a revised version of the paper "Limit shapes outside the percolation cone." We changed the title and included a new appendix which allows the moment assumption of the main logarithmic variance bound (Theorem 2.5) to be reduced from 2+beta moments (beta positive) to 2 moments

description: We propose an interpolation expression using the difference moment (Kolmogorov transient structural function) of the second order as the average characteristic of displacements for identifying the anomalous diffusion in complex processes when the stochastic dynamics of the system under study reaches a steady state (large time intervals). Our procedure based on this expression for identifying anomalous diffusion and calculating its parameters in complex processes is applied to the analysis of the dynamics of blinking fluorescence of quantum dots, X-ray emission from accreting objects, fluid velocity in Rayleigh-Bénard convection, and geoelectrical signal for a seismic area. For all four examples, the proposed interpolation is able to adequately describe the stochastic part of the experimental difference moment, which implies that anomalous diffusion manifests itself in these complex processes. The results of this study make it possible to broaden the range of complex natural processes in which anomalous diffusion can be identified.

description: Assuming that the natural gauge group of gravity is given by the group of isometries of a given space, for a maximally symmetric space we derive a model in which gravity is essentially a gauge theory of translations. Starting from first principles we verify that a nonlinear realization of the symmetry provides the general structure of this gauge theory, leading to a simple choice of dynamical variables of the gravity field corresponding, at first order, to a diagonal matrix, whereas the non-diagonal elements contribute only to higher orders.

Relearning religious practice when home is across the sea : the case of Tenrikyō in British Columbia
Creators: name: Chan, Emmett Sebastian
Publisher: name: University of British Columbia
Year: 2020

description: The Japanese New Religious Movement, Tenrikyō, views a specific geographical point in Tenri City, Japan as the “Origin” (jiba)—where humanity was conceived by God the Parent, the central deity of Tenrikyō, and a number of other deities. Identified by their foundress, Miki Nakayama, in the 19th century, and the location of Tenrikyō headquarters today, the jiba is far across the ocean from followers whose families migrated to Vancouver, British Columbia. In a religious sense, followers living in overseas diaspora communities have become both physically and spiritually displaced from their Origin. In this thesis, I examine how Tenrikyō adherents in Vancouver practice when they are so distant from the “Origin.” Based on fieldwork and interviews, I have found that many choose, or desire, to return to the Origin. I argue that at the Origin and the surrounding sacred landscape followers become immersed in intensive, daily group practice. These intensive experiences are crucial for active followers to develop a connection the Origin and the surrounding sacred landscape and this connection continues to be important after they leave Tenri City. After they leave Tenri City, practice then becomes a matter of re-learning how to be at-a-distance from the Origin and the surrounding sacred landscape. Followers in Vancouver come to face the anxieties and difficulties associated with practicing in the area and begin to feel a nostalgic longing for the immersive environment they had experienced. While in Vancouver, followers maintain this connection to the Origin and the surrounding sacred landscape in Tenri City from afar through monthly services. These services invoke a sense of nostalgia through ritual, clothing, food and events but leave those who have not yet been to the Origin feeling no connection or sense of nostalgia. For this reason it becomes ever more important for Tenrikyō followers in Vancouver to encourage people to return to the Origin and the surrounding area, so they too may establish a connection.

Instability of Compressible Drops and Jets

description: We revisit the classic problem of the stability of drops and jets held by surface tension, while regarding the compressibility of bulk fluids and spatial dimensions as free parameters. By mode analysis, it is shown that there exists a critical compressibility above which the drops (and disks) become unstable for a spherical perturbation. For a given value of compressibility (and those of the surface tension and density at the equilibrium), this instability criterion provides a minimal radius below which the drop cannot be a stable equilibrium. According to the existence of the above unstable mode of drop, which corresponds to a homogeneous perturbation of cylindrical jet, the dispersion relation of Rayleigh-Plateau instability for cylinders drastically changes. In particular, we identify another critical compressibility above which the homogeneous unstable mode is predominant. The analysis is done for non-relativistic and relativistic perfect fluids, of which self-gravity is ignored.

description: Mineralogical, geochemical and S-isotopic studies were carried out on seafloor massive sulfides (SMS) and hydrothermally altered rocks from the mafic-hosted TaiJi field (including TaiJi-1 and TaiJi-2 sites), which is located on the margin of a nontransform discontinuity (NTD) on the Southern Mid-Atlantic Ridge (SMAR). The main hydrothermal precipitates of TaiJi-1 were massive sulfides, while TaiJi-2 produced a large amount of semi-massive sulfides. Significant rock alteration is an important feature of this field, and large amounts of clay minerals (chlorite) occurred in the semi-massive sulfides. Geochemically, notable negative correlations were identified between rock forming elements (Mg) and major hydrothermal metal elements such as Zn + Cu and Co in semisulfides. Such mineralogical and geochemical characteristics, together with low Co/Ni ratio (similar to the surrounding rocks) of the semi-massive sulfides and the unique REE features of some altered rocks, tell us that the prominent mineralization mechanism for these semi-massive sulfides was probably related to rock mineralization. Thus, TaiJi-2 appears to differ significantly from the TaiJi-1 in terms of sulfide mineralization mechanism. Moreover, the TaiJi sulfides are remarkable for large δ34S variation (7.2–15.3%). We suggest that seawater corrosion after sulfides precipitation were responsible for 34S enrichment in sulfides. Furthermore, our work sheds some light on the comparison between TaiJi and other NTD-related fields along the Mid-Atlantic Ridge. We argue that rock mineralization may represent an important mineralization type in NTDs.

description: O presente estudo científico pretendeu comparar a aptidão física em praticantes de futsal e basquetebol com o objetivo de analisar os efeitos da especificidade do treino. Recorreu-se a atletas juvenis masculinos de futsal e de basquetebol (n=8, em ambas as modalidades) e obtiveram-se os seguintes valores antropométricos: futsal, altura 1.75±0.09 m, peso 67.81±14.27 kg e índice de massa corporal (IMC) 22.05±3.54 kg/m2; basquetebol, altura 1.80±0.06 m, peso 68.53±6.14 kg e IMC 21.16±2.58 kg/m2. Após a aplicação da bateria de testes para análise da aptidão física, observamos diferenças estatisticamente significativas entre as duas modalidades na avaliação da força dos membros superiores (n.º flexões: P=0.018) apresentando valores superiores para a equipa de basquetebol (basque-tebol: 28.38±2.13; futsal: 21.13±6.71). No teste de força dos membros inferiores não se verificou uma diferença significativa (squat jump: P=0.120; basquetebol: 1.65±0.23 m e futsal: 1.50±0.12 m). Na avaliação da coordenação (sprint 10 m com contorno de obstáculos) os atletas de futsal apresentaram valores superiores comparativamente aos de basquetebol (P=0.000, 7.40±1.49 seg. e 11.84±1.04 seg., respetivamente). Relativamente ao sprint de 20 m livres observou-se o con-trário (P=0.013, 3.38±0.21 seg. e 3.13±0.10 seg., respetivamente). Por último, nos testes de flexibilidade, verificou-se que os atletas de futsal possuem flexibilidade superior nos 3 testes realizados, comparativamente aos basquetebolistas. Os jo-gadores de basquetebol possuem mais força ao nível dos membros inferiores e superiores mas menos velocidade, agilidade e flexibilidade comparativamente aos jogadores de futsal.

recommendations
research rewards and incentives

description: The results summarised in this deliverable are intended to enable Open Science policy to move beyond the current state-of-the-art to better incorporate a self-reflexive critique of the consequences of policy interventions and to reveal gaps and deficiencies in current policy measures. This the project hopes to achieve by making evidence-based policy recommendations on how stakeholders (Research Performing Organisations, Research Funders, and other stakeholders) should amend indicators and reward/incentive schemes to address and/or mitigate these factors, thus breaking new ground for equitable Responsible Research and Innovation. This deliverable is structured as follows: Section 2 presents a systematic Scoping Review of current evidence on ON-MERRIT’s major focus of dynamics of cumulative advantage and threats to equity in Open Science, with reference to related factors in RRI. Section 3 presents an overview of the findings from ON-MERRIT’s research into research cultures, support and incentives (deriving mainly from Work Package 3), including reference to specific findings of relevance to ON-MERRIT’s target Sustainable Development Goals. Section 4 presents an overview of the findings from ON-MERRIT’s research into Innovation and industry (Work Package 4), including reference to specific findings of relevance to ON-MERRIT’s target SDGs. Section 5 presents an overview of the findings from ON-MERRIT’s research into Policy-making and societal actors (Work Package 5), including reference to specific findings of relevance to ON-MERRIT’s target SDGs. Section 6 presents findings from across the project on issues related to gender equity and the transition to Open Science and RRI. Section 7 concludes by reviewing key findings and relating this to the final tasks of ON-MERRIT to create policy recommendations.

DASH model

description: Over the past 28 months, ON-MERRIT has collected evidence on how Open Science reshapes scientific endeavours and their interaction with societies and industries, conducting interviews, surveys, group discussions, document analysis and the analysis of large bibliographic databases. While a host of empirical results are now available via several comprehensive deliverables, the ON-MERRIT consortium is conducting a final and key step: synthesizing the knowledge gained and distilling it into actionable recommendations. The final recommendations will be based on the evidence collected so far, and refined in light of highly productive discussions with domain experts. Still, assessing the recommendation’s efficacy and any unintended consequences based on the relationship “evidence about system A” → policy is hard. To close the circle by investigating the relationship policy → “change in system A”, this deliverable leverages the method of Agent-Based Modelling (ABM) to assess outcomes of potential policies by modelling patterns of the uptake of Open Science (OS) under policies proposed in the research literature. Data sharing has become an integral part of the OS agenda, and is central to an increasing number of policies. The sharing and subsequent re-use of research data is expected to lead to substantial efficiency gains across science and industry (Directorate-General for Research and Innovation, 2016). There is substantial evidence that sharing of research data leads to a citation advantage (Colavizza et al., 2020; McKiernan et al., 2016). Game-theoretical approaches (Pronk et al., 2015) have highlighted that, as with many other aspects of OS, the overall adoption and uptake of data sharing can be understood as a problem of collective action (see also Scheliga & Friesike, 2014). That is, system-level benefits can be expected when sharing is the norm, while individuals may benefit from not sharing their own data while re-using data that others have shared (i.e., free-riding). In this deliverable, we develop and discuss the DASH (DAta Sharing) model, which leverages the potential of ABM to investigate how plausible scenarios of incentivising data sharing could encourage its uptake, given varying scenarios of costs associated with the sharing of data, as well as different strategies employed by individual research groups to decide on whether or not to share data. The model serves as a starting ground, enabling further evaluation of policy interventions for their efficacy, and potential repercussions for equity in science.

description: We compare current and forecasted constraints on dynamical dark energy models from Type Ia supernovae and the cosmic microwave background using figures of merit based on the volume of the allowed dark energy parameter space. For a two-parameter dark energy equation of state that varies linearly with the scale factor, and assuming a flat universe, the area of the error ellipse can be reduced by a factor of ~10 relative to current constraints by future space-based supernova data and CMB measurements from the Planck satellite. If the dark energy equation of state is described by a more general basis of principal components, the expected improvement in volume-based figures of merit is much greater. While the forecasted precision for any single parameter is only a factor of 2-5 smaller than current uncertainties, the constraints on dark energy models bounded by -1

description: This paper studies the stability of warm inflationary solutions when the viscous pressure is taken into account. The latter is a very natural and physically motivated ingredient of warm inflation and is seen to widen the stability range of warm inflation. The spectral index parameters, $n_{s}$, $n_{T}$, and their ratio are derived. The corresponding WMAP7 data are used to fix some parameters of the model. Two specific examples are discussed in detail: (i) a potential given by $V(ϕ, T) = v_{1}(ϕ)\, + \, v_{2}(T)$, and (ii) a potential of the form $V(ϕ, T) = α\, v_{1}(ϕ) \, v_{2}(T)$. In both cases, the viscosity has little impact on the said ratio.

description: Na evolução das creches em Portugal verifica-se uma alternância entre conceções assistencialista de integração educacional. Procura-se refletir sobre a tensão existente entre estas duas perspetivas relativamente ao atendimento em creche em Portugal. A creche foi considerada como local de guarda por impedimento dos pais, no entanto no decurso dos tempos assistimos a tentativas de a assumir como um serviço de prestação de cuidados e de educação promovendo um desenvolvimento mais holístico e respeitador dos direitos das crianças. Absract In the evolution of nurseries in Portugal there is an alternation between welfare conceptions and educational integration. Wanted reflect on the tension between these two perspectives regarding the attendance at day care in Portugal. The nursery was considered as a place of guard for offside parents, however in the course of time we have seen attempts to take over as a service providing care and education to promote a more holistic and respectful development of children's rights.
