description: Abstract: The aim of our study was to investigate phenotypic and genotypic features of streptococci misidentified (misID) as Streptococcus pneumoniae, obtained over 20 years from hospital patients in Poland. Sixty-three isolates demonstrating microbiological features typical for pneumococci (optochin susceptibility and/or bile solubility) were investigated by phenotypic tests, lytA and 16S rRNA gene polymorphism and whole-genome sequencing (WGS). All isolates had a 6-bp deletion in the lytA 3′ terminus, characteristic for Mitis streptococc and all but two isolates lacked the pneumococcal signature cytosine at nucleotide position 203 in the 16S rRNA genes. The counterparts of psaA and ply were present in 100% and 81.0% of isolates, respectively; the spn9802 and spn9828 loci were characteristic for 49.2% and 38.1% of isolates, respectively. Phylogenetic trees and networks, based on the multilocus sequence analysis (MLSA) scheme, ribosomal multilocus sequence typing (rMLST) scheme and core-genome analysis, clearly separated investigated isolates from S. pneumoniae and demonstrated the polyclonal character of misID streptococci, associated with the Streptococcus pseudopneumoniae and Streptococcus mitis groups. While the S. pseudopneumoniae clade was relatively well defined in all three analyses, only the core-genome analysis revealed the presence of another cluster comprising a fraction of misID streptococci and a strain proposed elsewhere as a representative of a novel species in the Mitis group. Our findings point to complex phylogenetic and taxonomic relationships among S. mitis-like bacteria and support the notion that this group may in fact consist of several distinct species.
Choked accretion onto a Schwarzschild black hole: A hydrodynamical jet-launching mechanism

description: We present a novel, relativistic accretion model for accretion onto a Schwarzschild black hole. This consists of a purely hydrodynamical mechanism in which, by breaking spherical symmetry, a radially accreting flow transitions into an inflow-outflow configuration. The spherical symmetry is broken by considering that the accreted material is more concentrated on an equatorial belt, leaving the polar regions relatively under-dense. What we have found is a flux-limited accretion regime in which, for a sufficiently large accretion rate, the incoming material chokes at a gravitational bottleneck and the excess flux is redirected by the density gradient as a bipolar outflow. The threshold value at which the accreting material chokes is of the order of the mass accretion rate found in the spherically symmetric case studied by Bondi and Michel. We describe the choked accretion mechanism first in terms of a general relativistic, analytic toy model based on the assumption of an ultrarelativistic stiff fluid. We then relax this approximation and, by means of numerical simulations, show that this mechanism can operate also for general polytropic fluids. Interestingly, the qualitative inflow-outflow morphology obtained appears as a generic result of the proposed symmetry break, across analytic and numeric results covering both the Newtonian and relativistic regimes. The qualitative change in the resulting steady state flow configuration appears even for a very small equatorial to polar density contrast ($\sim 0.1\,\%$) in the accretion profile. Finally, we discuss the applicability of this model as a jet-launching mechanism in different astrophysical settings.

description: The factorization of soft and ultrasoft gluons from collinear particles is shown at the level of operators in an effective field theory. Exclusive hadronic factorization and inclusive partonic factorization follow as special cases. The leading order Lagrangian is derived using power counting and gauge invariance in the effective theory. Several species of gluons are required, and softer gluons appear as background fields to gluons with harder momenta. Two examples are given: the factorization of soft gluons in B->D pi, and the soft-collinear convolution for the B->Xs gamma spectrum.

description: This paper explores disruptive poverty politics arising from creative activisms that challenge homelessness/impoverishment. We analyze forms and potentials of creative activisms that challenge hegemonic meanings and practices around impoverishment. Bringing together geographers’ work on creative activisms, geographies of art, and the dialectics of thinkable and unthinkable poverty politics; we analyze activism by Real Change, a Seattle economic and racial justice organization confronting the city’s shelter crisis. We argue that creative poverty activism produces performative encounters that challenge exclusionary space-making and create political connections between people experiencing poverty and those who are not. Using portraiture and public art/performance, activists disrupt normative sights, practices, and socio-spatial relations on which poverty knowledge rests in public spaces. These interventions re-script spaces of privilege produced through capitalist relations of dispossession and exclusion, and the ideological projects that undergird them. Disruptive poverty politics create encounters across socio-spatial difference that challenge privileged subjects, raise new voices, and create previously unimaginable political forms. Our analysis extends prior work on visual poverty politics that has theorized the reproduction of hegemonic poverty politics (of difference, blame, stigma, individualized causes) through representational practices. We extend relational poverty analysis into the realm of the visual, performative, and creative, revealing new sites, forms, and possibilities of disruptive poverty politics.

description: In this paper we investigate the innermost stable circular orbit (ISCO) of a spinning test particle moving in the rotating Maxwell-dilaton black hole spacetime. By using the Mathisson-Papapetrou-Dixon equations along with the Tulczyjew spin-supplementary condition, we find the equations of motion in the equatorial plane and, from the radial equation, it is obtained the effective potential for the description of the particle's motion. The obtained trajectories show that the ISCO radii for spinning particles moving in rotating charged backgrounds are always smaller than those obtained in the corresponding Kerr-Newman spacetimes. The increasing in the particle's spin produces a decrease in the ISCO radius in all the studied cases, with a maximum value for the spin and a corresponding minimum ISCO radius, obtained by imposing a condition that guarantees the timelike nature of the particle's worldline.

description: In the selective withdrawal experiment fluid is withdrawn through a tube with its tip suspended a distance S above an unperturbed two-fluid interface. At low withdrawal rates, Q, the interface forms a steady state hump and only the upper fluid is withdrawn. When Q is increased (or S decreased), the interface undergoes a transition so that the lower fluid is entrained with the upper one, forming a thin steady-state spout. Near this discontinuous transition the hump curvature becomes very large and displays power-law scaling behavior. This scaling is used to show that steady-state profiles for humps at different flow rates and tube heights can all be scaled onto a single similarity profile.

description: In this article we describe our experiences with computational text analysis. We hope to achieve three primary goals. First, we aim to shed light on thorny issues not always at the forefront of discussions about computational text analysis methods. Second, we hope to provide a set of best practices for working with thick social and cultural concepts. Our guidance is based on our own experiences and is therefore inherently imperfect. Still, given our diversity of disciplinary backgrounds and research practices, we hope to capture a range of ideas and identify commonalities that will resonate for many. And this leads to our final goal: to help promote interdisciplinary collaborations. Interdisciplinary insights and partnerships are essential for realizing the full potential of any computational text analysis that involves social and cultural concepts, and the more we are able to bridge these divides, the more fruitful we believe our work will be.

Authenticity, authentication and experiential authenticity: telling stories in museums

Subjects: subject: Molecular Biology
subject: Sociology
subject: FOS: Sociology
subject: Science Policy

description: This article examines how different types of authenticity and authentication work together to inspire museum stories, and personal identification with them, in ways that encourage experiential authenticity. It begins by outlining conceptions of object and existential authenticity and demonstrating how they are bound up with processes of hot and cool authentication. I argue that museums deploy all of these mechanisms to encourage experiences which visitors perceive as authentic. This perspective supports a concept of ‘experiential authenticity’ which connotes the belief and sensations of having experienced something genuine and real. This concept’s value is illustrated by examining storytelling in Anne Frank House. Key museum stories are outlined before exploring how different forms, and degrees, of authenticity and authentication work together to enlist visitor imaginations in the storytelling process and to thereby inspire personal identification as well as embodied connections with them. Four key mechanisms for telling stories are analysed (objects, texts, photographs and videos), and their combined capacity to cultivate experiential authenticity is demonstrated. This is important because experiential authenticity heightens visitor receptivity to museum stories, and is thus both a source and agent of power.

description: We describe a model of hybrid quintessence in which in addition to the tracker field there is a trigger field which is responsible for ending quintessence. As a result, hybrid quintessence does not suffer from the problems associated with the eternal acceleration of the universe. We derive the hybrid quintessence potential on branes from the interbrane interaction in string theory and show that it requires TeV scale strings and two millimeter size dimensions. This scenario predicts a dark energy density of $O(mm^{-4})$ and relates the smallness of this energy to the large size of the extra dimensions.

We introduce a geometric description of the spin configurations in terms of triangles which play the role of contours and for which we establish Peierls bounds. This in particular yields a direct proof of the well known result by Dyson about phase transitions at low temperatures.

description: The new generation of deep photometric surveys requires unprecedentedly precise shape and photometry measurements of billions of galaxies to achieve their main science goals. At such depths, one major limiting factor is the blending of galaxies due to line-of-sight projection, with an expected fraction of blended galaxies of up to 50%. Current deblending approaches are in most cases either too slow or not accurate enough to reach the level of requirements. This work explores the use of deep neural networks to estimate the photometry of blended pairs of galaxies in monochrome space images, similar to the ones that will be delivered by the Euclid space telescope. Using a clean sample of isolated galaxies from the CANDELS survey, we artificially blend them and train two different network models to recover the photometry of the two galaxies. We show that our approach can recover the original photometry of the galaxies before being blended with $\sim$7% accuracy without any human intervention and without any assumption on the galaxy shape. This represents an improvement of at least a factor of 4 compared to the classical SExtractor approach. We also show that forcing the network to simultaneously estimate a binary segmentation map results in a slightly improved photometry. All data products and codes will be made public to ease the comparison with other approaches on a common data set.

description: Pivoting on the idea that differences in production and financial systems may affect monetary transmission mechanisms, a global vector autoregressive (GVAR) model is built and the effectiveness of monetary policy on the real economy in the Italian regions in the period 2000–16 is tested, also taking interaction effects into account. The results show that regional gross domestic product responds positively, but asymmetrically to an expansionary monetary policy, while prices fall in the short run. It is also shown that short- and long-term interest rates react in accordance with theory.

description: Abstract: Purpose: To study the associations of physical activity (PA), sedentary time (ST), and cardiorespiratory fitness (CRF) with heart rate variability (HRV) in children. Methods: The participants were a population sample of 377 children aged 6–9 years (49% boys). ST, light PA (LPA), moderate PA (MPA), vigorous PA (VPA), and moderate-to-vigorous PA (MVPA), and PA energy expenditure (PAEE) were assessed using a combined heart rate and movement sensor, maximal power output per kilograms of lean body mass as a measure of CRF by maximal cycle ergometer exercise test, and HRV variables (SDNN, RMSSD, LF, and HF) using 5 min resting electrocardiography. Data were analysed by linear regression adjusted for years from peak height velocity. Results: In boys, ST was inversely associated (β = − 0.185 to − 0.146, p ≤ 0.049) and MVPA, VPA, PAEE, and CRF were directly associated (β = 0.147 to 0.320, p ≤ 0.048) with HRV variables. CRF was directly associated with all HRV variables and PAEE was directly associated with RMSSD after mutual adjustment for ST, PAEE, and CRF (β = 0.169 to 0.270, p ≤ 0.046). In girls, ST was inversely associated (β = − 0.382 to − 0.294, p < 0.001) and LPA, MPA, VPA, MVPA, and PAEE were directly associated with HRV variables (β = 0.144 to 0.348, p ≤ 0.049). After mutual adjustment for ST, PAEE, and CRF, only the inverse associations of ST with HRV variables remained statistically significant. Conclusions: Higher ST and lower PA and CRF were associated with poorer cardiac autonomic nervous system function in children. Lower CRF in boys and higher ST in girls were the strongest correlates of poorer cardiac autonomic function.

description: This paper analyses the market of high fructose corn syrup (HFCS) in the United States. It develops a system of demand and supply equations for both the HFCS and soft drinks markets. The system of equations is estimated through Two Stage Least Squares methods. The results show that soft drinks are the main driver of the growth of demand for HFCS. In addition, negative news on HFCS (the association of HFCS consumption and obesity) has a negative effect on the growth of demand for soft drinks, but soft drinks per capita advertising has a positive effect on the growth of demand for soft drinks and more than offsets the effect of negative news.

description: We reduce the perturbative uncertainty in the determination of |V_{ub}| from inclusive semileptonic B decays by calculating the rate of B -> X_u l nu events with dilepton invariant mass q^2>(M_B-M_D)^2 at subleading order in the hybrid expansion, and to next-to-leading order in renormalization-group improved perturbation theory. We also resum logarithmic corrections to the leading power-suppressed contributions. Studying the effect of different b-quark mass definitions we find that the branching ratio after the cut is Br(B -> X_u l nu)=(20.9+-4.0)|V_{ub}|^2, where the dominant error is due to the uncertainty in the b-quark mass. This implies that |V_{ub}| can be determined with a precision of about 10%.

description: Massive stars are characterized by a significant loss of mass either via spherically symmetric stellar winds or pre-explosion pulses, or by aspherical forms of circumstellar matter (CSM) such as bipolar lobes or outflowing circumstellar equatorial disks. A significant fraction of most massive stars end their lives by a core collapse; supernovae (SNe) are always located inside circumstellar envelopes created by their progenitors. We study the dynamics and thermal effects of collision between expanding ejecta of SNe and CSM that may be formed during, for example, a sgB[e] star phase, a luminous blue variable phase, around PopIII stars, or by various forms of accretion. For time-dependent hydrodynamic modeling we used our own code built with a finite volumes method. The code is highly efficient for calculations of shocks and physical flows with large discontinuities. The initial geometry of the disks corresponds to a density structure of a material that orbits in Keplerian trajectories. We examine the behavior of the density, pressure, velocity of expansion, and temperature structure in the interaction zone under various geometrical configurations of dense equatorial disks. Our `low density' model shows significant asphericity in the case of the disk mass-loss rate $\dot{M}_\text{csd}=10^{-6}\,M_\odot\,\text{yr}^{-1}$. The models also show the zones of overdensity in the SN - disk contact region and indicate the development of Kelvin-Helmholtz instabilities within the zones of shear between the disk and the more freely expanding material outside the disk.

We discuss behavior of the total cross-section of virtual photon-proton scattering and obtain, in particular, that the exponent in the power-like dependence of $σ^{tot}_{γ^* p}$ is related to the interaction radius of a constituent quark. The explicit mass dependence of the exponent in the power energy behavior of the vector meson electroproduction has been obtained. Angular distributions at large momentum transfers are considered. The energy dependence of the total cross-section of $γ^*γ^*$-interactions is also obtained.

description: Waste management is a global conservation issue and efforts continue in an attempt to reduce, reuse and recycle waste that is collected.. In an effort to reduce the amount of waste entering landfills, the Florida Legislature adopted a goal that aims to achieve 75% recycling rate of municipal solid waste collected by 2020. This paper examines the current state policy tools in increasing recycling while controlling for socioeconomic factors that may affect recycling rate. We estimated the effect by difference in difference regression method and compared the pre- and post-treatment effects of these policies using county level panel data from 2001 to 2013. Our results indicate that that there is a positive treatment effect on recycling rate, especially with regards to public educational outreach. The existence of a mandatory commercial recycling policy also had a positive association with the increase in commercial recycling rate and influenced the overall recycling rate.

description: This paper studies the effect of income transfers on the distribution of economic activity through a modified FE model. The model incorporates some key features of the Dutch disease literature: sectorial mobility and non-tradable goods. If foreign competition is high (high trade openness), transfers could cause a Dutch disease in the short and long runs. For intermediate levels of foreign competition, Dutch disease appears only in the short run. And, for low levels, the recipient region always benefits from the income transfers. Additionally, when economies of scale are large, the transfers could perpetuate a core–periphery structure.

description: Abstract: Background: Limited data are available regarding correlates of regular sexually transmitted infections (STIs) and HIV screening among female sex workers (FSW) in Sub-Saharan Africa. In this study, we aimed to assess the frequency of regular syphilis and HIV screening and the psychosocial correlates associated with screening among FSW in Uganda. Methods: This cross-sectional correlational study was conducted among 441 FSW, aged 17–49 years. We enrolled FSW through peer referrals and ascertained self-reported data on number of serological tests for HIV, syphilis and other STIs in the prior 12 months using an interviewer-administered questionnaire. In addition, we assessed attitudes, norms, social influences and self-efficacy towards 3-monthly Syphilis and 6-monthly HIV testing. We estimated the correlates of regular STI and HIV testing using negative binomial regression. Results: Of the respondents 420 (95.2%) reported to have ever taken an HIV test with 297 (67.4%) testing two or more times in the prior 12 months. Over half of the respondents (59%) reported ever taking a syphilis test with only 62 (14.1%) reporting testing three or more times in the prior 12 months. After adjusting for socio-demographics, attitude and norms, high perceived self-efficacy was associated with a 33% increase in the likelihood of repeated HIV testing [prevalence ratio (PR), 1.33, 95% confidence interval (CI) 1.15–1.53] while low perceived confidence was associated with a 25% decrease in the likelihood of repeated HIV testing (PR, 0.75, 95% CI 0.63–0.89). Similarly low attitudes and norms were associated with a decrease of 52.6% (PR, 0.47, 95% CI 0.37–0.61) and 47% (PR, 0.53, 95% CI 0.41–0.69) in the likelihood of repeated syphilis testing respectively. Conclusion: Compared to HIV, uptake of repeated syphilis testing was very low. Correlates of HIV testing include; perceived self-efficacy amidst barriers and perceived confidence for HIV and low attitudes and accepting norms for syphilis. Health campaigns should emphasize overcoming barriers to HIV testing while promoting attitudes and norms including integration of serological syphilis testing and other STIs into HIV services.

description: It is known that a graded lattice of rank n is supersolvable if and only if it has an EL-labelling where the labels along any maximal chain are exactly the numbers 1,2,...,n without repetition. These labellings are called S_n EL-labellings, and having such a labelling is also equivalent to possessing a maximal chain of left modular elements. In the case of an ungraded lattice, there is a natural extension of S_n EL-labellings, called interpolating labellings. We show that admitting an interpolating labelling is again equivalent to possessing a maximal chain of left modular elements. Furthermore, we work in the setting of a general bounded poset as all the above results generalize to this case. We conclude by applying our results to show that the lattice of non-straddling partitions, which is not graded in general, has a maximal chain of left modular elements.

Scaling dependence on the fluid viscosity ratio in the selective withdrawal transition

description: In the selective withdrawal experiment fluid is withdrawn through a tube with its tip suspended a distance S above a two-fluid interface. At sufficiently low withdrawal rates, Q, the interface forms a steady state hump and only the upper fluid is withdrawn. When Q is increased (or S decreased), the interface undergoes a transition so that the lower fluid is entrained with the upper one, forming a thin steady-state spout. Near this transition the hump curvature becomes very large and displays power-law scaling behavior. This scaling allows for steady-state hump profiles at different flow rates and tube heights to be scaled onto a single similarity profile. I show that the scaling behavior is independent of the viscosity ratio.

description: This paper estimates the relative preferences of motorists for E10 and E85 from an intercept survey of motorists with flex-fuel vehicles at E85 fuel stations in Arkansas, California, Colorado, Iowa, and Oklahoma. The information collected includes prices observed at fuel stations, fuel choices by flex motorists, and responses to a series of opinion questions about ethanol and gasoline. We also proposed a hypothetical scenario to each motorist in which either the price of the fuel selected was increased or the price of the fuel not selected was decreased. We first estimate fuel preferences using the revealed preference data from the observed choices. We then use the stated preference data from the hypothetical price scenario to estimate preferences in empirical models that correct for endogeneity from unobservable demand shifters that carry over to the stated preference empirical model. We find that motorists significantly discount E85 compared to E10 even when accounting for the different energy content of the two fuels and that the distribution of willingness to pay for E85 does not vary significantly between regions, except for California where motorists are willing to pay significantly more for E85.

description: Using “chain-based and constant-based” two-step method, this paper measured Paasche net barter terms of index for Sino-Australian agricultural products from 2001 to 2013, and further calculated contribution of each category of agricultural products to changes in overall net barter terms of trade. The results showed that since 2001, the overall net barter terms of trade for Sino-Australian agricultural products fluctuated between deterioration and improvement. In 2013, the net barter terms of trade index was 1.02, and its improvement is not significant. From 2001 to 2013, the net barter terms of trade for Sino-Australian agricultural products improved about 16.44%, which dominated by the category 0 agricultural products whose influence degree is 6 times and 28 times the degree of category 4 and category 1. In years when the net barter terms of trade for Sino-Australian agricultural products deteriorated, category 2 agricultural products were the root cause for the deterioration.

description: This paper presents a case study demonstrating the process used to develop an overland flow model of radionuclide transport following an aerosol deposition from a hypothetical radiological dispersal device explosion. The process included the integration of digital elevation, building, and land cover information with hydrologic information from a calibrated Stormwater Management Model (SWMM) model. The overland flow model was used to explore the impact of washoff parameter selection and different storm events on radionuclide transport in surface flow. The range of washoff parameters used in the literature resulted in over a 7 times difference in radionuclide washoff, from a small surface removal to nearly full removal. The overland flow model illuminated the primary pathways of contaminant transport, a potentially useful tool that informs emergency response, planning, and remediation activities.

description: With the explosive development of mobile Internet, short text has been applied extensively. The difference between classifying short text and long documents is that short text is of shortness and sparsity. Thus, it is challenging to deal with short text classification owing to its less semantic information. In this paper, we propose a novel topic-based convolutional neural network (TB-CNN) based on Latent Dirichlet Allocation (LDA) model and convolutional neural network. Comparing to traditional CNN methods, TB-CNN generates topic words with LDA model to reduce the sparseness and combines the embedding vectors of topic words and input words to extend feature space of short text. The validation results on IMDB movie review dataset show the improvement and effectiveness of TB-CNN.

description: Abstract: Bone morphogenetic proteins (BMPs) are multifunctional cytokines of the transforming growth factor β (TGFβ) superfamily with potential therapeutic applications due to their broad biological functionality. Designing BMP mimetics with specific activity will contribute to the translational potential of BMP-based therapies. Here, we report a BMP9 peptide mimetic, P3, designed from the type I receptor binding site, which showed millimolar binding affinities for the type I receptor activin receptor like kinase 1 (ALK1), ALK2 and ALK3. Although showing no baseline activity, P3 significantly enhanced BMP9-induced Smad1/5 phosphorylation as well as ID1, BMPR2, HEY1 and HEY2 gene expression in pulmonary artery endothelial cells (hPAECs), and this activity is dependent on its alpha helix propensity. However, in human dermal microvascular endothelial cells, P3 did not affect BMP9-induced Smad1/5 phosphorylation, but potently inhibited ALK3-dependent BMP4-induced Smad1/5 phosphorylation and gene expression. In C2C12 mouse myoblast cells, P3 had no effect on BMP9-induced osteogenic signalling, which is primarily mediated by ALK2. Interestingly, a previously published peptide from the knuckle region of BMP9 was found to inhibit BMP4-induced Smad1/5 phosphorylation. Together, our data identify a BMP9-derived peptide that can selectively enhance ALK1-mediated BMP9 signalling in hPAECs and modulate BMP9 and BMP4 signalling in a cell type-specific manner.

description: Urban runoff remobilises solids and their associated pollutants from urban-built environments and transports them to drainage systems via gully pots. This study presents an extensive monitoring campaign on the solids loading to drainage systems, including 104 gully pots as sampling locations and lasting 2 years. The solids loading is modelled with Build-Up and Wash-Off (BUWO) models and a Regression Tree (RT). The performance of the RT is substantially better than the performance of the BUWO models, such that it is not recommended to use a single BUWO model to predict the loading of a set of gully pots/catchments. It is discussed whether the generally observed mismatch between monitoring data and wash-off models, both in this study and in literature, points to a fundamental misunderstanding of the underlying processes. Finally, the results show that an increased street sweeping frequency does not significantly reduce the solids loading to drainage systems.
