Measuring Model-independent Masses and Radii of Single-lined Eclipsing Binaries: Analytic Precision Estimates
Authors: Stevens Daniel J. , Gaudi B. Scott , Stassun Keivan G. 
Published: July 2018

Abstract
We derive analytic estimates for the ability with which one can obtain precise, empirical stellar masses and radii via single-lined eclipsing binaries (EBs) in the era of Gaia and TESS. Including stars that host transiting substellar companions, such single-lined EBs already number in the hundreds from ground-based transit surveys and will comprise a major component of the science yield from the upcoming TESS mission. We explore the requirements for obtaining a given fractional precision on the masses and radii of single-lined EBs using primarily empirical means: radial velocity and eclipse measurements along with estimates of the primary’s (1) surface gravity from high-resolution spectroscopy; (2) radius inferred from parallax, effective temperature, and bolometric flux; or (3) surface gravity and density from asteroseismology. We then compare these requirements to the precision obtained from invoking stellar models or empirical relations. We show that, for a fiducial transiting hot Jupiter system, precise, accurate, and essentially model-independent mass and radius measurements for such single-lined EBs will be possible in the era of Gaia. These will be comparable in precision to those obtained with double-lined EBs. Moreover, the systems for which these methods can be applied will vastly outnumber double-lined EBs, thereby possessing the potential to sample a more complete range of stellar types (such as M dwarfs); these systems will also, in many cases, be more amenable to precision metallicity and abundance determinations than are double-lined EBs.
Kavain Reduces Porphyromonas gingivalis–Induced Adipocyte Inflammation: Role of PGC-1α Signaling

Published: July 2018

Abstract
A link between obesity and periodontitis has been suggested because of compromised immune response and chronic inflammation in obese patients. In this study, we evaluated the anti-inflammatory properties of Kavain, an extract from Piper methysticum, on Porphyromonas gingivalis–induced inflammation in adipocytes with special focus on peroxisome proliferation–activated receptor γ coactivator α (PGC-1α) and related pathways. The 3T3-L1 mouse preadipocytes and primary adipocytes harvested from mouse adipose tissue were infected with P. gingivalis, and inflammation (TNF-α; adiponectin/adipokines), oxidative stress, and adipogenic marker (FAS, CEBPα, and PPAR-γ) expression were measured. Furthermore, effect of PGC-1α knockdown on Kavain action was evaluated. Results showed that P. gingivalis worsens adipocyte dysfunction through increase of TNF-α, IL-6, and iNOS and decrease of PGC-1α and adiponectin. Interestingly, although Kavain obliterated P. gingivalis–induced proinflammatory effects in wild-type cells, Kavain did not affect PGC-1α–deficient cells, strongly advocating for Kavain effects being mediated by PGC-1α. In vivo adipocytes challenged with i.p. injection of P. gingivalis alone or P. gingivalis and Kavain displayed the same phenotype as in vitro adipocytes. Altogether, our findings established anti-inflammatory and antioxidant effects of Kavain on adipocytes and emphasized protective action against P. gingivalis–induced adipogenesis. The use of compounds such as Kavain offer a portal to potential therapeutic approaches to counter chronic inflammation in obesity-related diseases.
Exodus of clergy: ‘When the fight is just not worth it anymore’ – The role of conflict in responding to the call
Authors: Joynt Shaun 
Published: July 2018

Conflict affects clergy’s response to the call. Unresolved conflict negatively influences their decision to remain in full-time pastoral ministry. This contributes to a shortage of clergy in the Roman Catholic Church, but to a lesser extent, the Protestant church, as it faces a distribution or displacement challenge. The shortage negatively affects the church, as clergy equip congregants to live the faith and transmit it to the next generation. The purpose of this study is to discover what factors are involved in responding to the call to full-time pastoral ministry. A practical theological grounded theory approach is used to discover the properties of the basic social process responding to the call and more specifically one of its categories, namely conflict. Semi-structured interviews are conducted and data coded, using Glaser and Strauss’ grounded theory methodology in order to determine a basic social process, namely responding to the call. The category of ‘conflict’ includes properties such as conflict due to lack of communication, dealing with favouritism, conflict with leadership and managing conflict or leaving due to conflict. Osmer’s descriptive-empirical task is used to view the category conflict from a practical theological perspective. The results of this study indicate three responses to the call by clergy who left full-time pastoral ministry: not called in the first place, a dual call (being bi-vocational or seasonal), and being called, but leaving anyway due to, among other factors, conflict.

Published: July 2018

Objective:
Many erectile dysfunction (ED) cases are attributed to vascular endothelial dysfunction and impaired blood flow due to arteriosclerotic changes. In this study, we examined the association among the erection hardness score (EHS), pulse wave velocity (PWV), and the presence of carotid artery plaques.

Subjects and Methods:
The study enrolled 67 patients who visited our hospital with the chief complaint of ED. Based on the history at the first visit, 28 of the 67 patients were categorized into the EHS 3–4 group and the remaining 39 into the EHS 0–2 group. The two groups were retrospectively analyzed.

Results:
The PWV points were significantly higher in the EHS 0–2 group than in the EHS 3–4 group (P = 0.047). In consideration for error in age, the modified points (PWV at the first visit – reference PWV by age) were significantly higher in the EHS 0–2 group than in the EHS 3–4 group (P = 0.026). This group also showed a higher detection rate of plaques by carotid ultrasound (66.7%).

Conclusion:
This study showed that patients with lower points of EHS had higher PWV and were more likely to have carotid artery plaques. While ED has occasionally been considered as an early risk marker for the onset of cardiovascular events; this study suggests that the hardness of the penis can be an easier-to-measure and more sensitive index.
Mixed Perverse Sheaves on Flag Varieties for Coxeter Groups
Authors: Achar Pramod N. , Riche Simon , Vay Cristian 
Published: July 2018

AbstractIn this paper we construct an abelian category of mixed perverse sheaves attached to any realization of a Coxeter group, in terms of the associated Elias–Williamson diagrammatic category. This construction extends previous work of the first two authors, where we worked with parity complexes instead of diagrams, and we extend most of the properties known in this case to the general setting. As an application we prove that the split Grothendieck group of the Elias–Williamson diagrammatic category is isomorphic to the corresponding Hecke algebra, for any choice of realization.
Income inequality and saving in a class society: the role of ordinal status
Authors: Haagsma Rein 
Published: July 2018

AbstractThis paper examines the impact of income growth and income inequality on household saving rates and payoffs in a non-cooperative game where each player’s payoff depends on her present and future consumption and her rank in the present consumption distribution. The setting is a pooling equilibrium with three clusters of successive income groups, each cluster having its own present-consumption standard and rank in the present-consumption distribution. In this way the analysis addresses the saving behaviour and welfare of three social classes: the lower, middle and upper class. Explanations are found for the Easterlin paradox and the Kuznets consumption puzzle and it is concluded that rank concerns tend to strengthen the case for more income equality and weaken the standard effect of inequality on aggregate saving.
Products, Promotion, and (Possibly) Profits: Sports Entrepreneurship Revisited
Authors: Vamplew Wray 
Published: July 2018

Abstract
This article provides two new definitions in sports history: first, the sport product, which is seen as encompassing player, spectator, and associated products; and, second, sports entrepreneurship, which covers the four categories of direct income seeking, indirect income seeking, psychic income seeking, and nonprofit promotional activities. Within these categories, attention is drawn to sports entertainment and “dark” entrepreneurs, as well as the historical importance of examining entrepreneurial failure. Two typologies of sports entrepreneurs are presented, one looking at aims and objectives and the other at function. It is argued that socio-cultural sports historians should not ignore economic aspects of sports provision.
Methicillin-resistant Staphylococcus aureus Swab Results Did Not Change Treatment or Outcome in Pediatric Spinal Fusion Patients

Published: July 2018

Introduction:
The aim of this study was to investigate whether preoperative methicillin-resistant Staphylococcus aureus (MRSA) swab results were predictive of surgical site infections (SSIs) in pediatric patients who have undergone spinal fusion.

Methods:
We conducted a retrospective chart review of patients who underwent posterior spinal fusion between 2004 and 2014 to determine preoperative MRSA colonization status and SSI rates and organisms. Before October 1, 2012, we administered vancomycin to the patients for infection prophylaxis; beginning October 1, 2012, patients received ceftazidime and Ancef (cefazolin for injection; GlaxoSmithKline). We added powdered vancomycin to all bone grafts.

Results:
A total of 1,200 patients met inclusion criteria. Of the patients, 2.3% (n = 28 of 1,200) were positive for MRSA, and an SSI developed in 3.1% (n = 37 of 1,200). No significant difference in infection rates was found between patients whose MRSA swab was positive and negative (positive swab = 1 SSI, negative swab = 36 SSIs; P = 0.88). Three SSIs were caused by MRSA.

Conclusion:
The results of a preoperative MRSA nasal swab had no correlation with SSI rates.

Level of Evidence:

Published: July 2018

The Real Plan of stabilization brought about great transformations in the financial sector of the country and paved the way for the development of alternative forms of resource applications. The funds characterized as variable income and multimarket have been analyzed in several academic studies, but there is still a lack of concern with the Real Estate Investment Funds (FII), which are backed by civil construction assets. This article aims at partially remedying this gap by analyzing the performance of FII in a period of economic downturn. The sample includes forty-four funds registered at Comissão de Valores Mobiliários (CVM) that presented daily quotations from August 2013 to September 2016. The approach is quantitative, using economic and financial indicators (Sharpe and Sortino indexes), regression analysis (Alfa de Jensen) and the Data Envelopment Analysis (DEA) optimization model. The results were not favorable to the FIIs as an attractive alternative to the application of resources in the analyzed period. Taking into account the risk and return, few funds were able to surpass the market benchmark. The methodological procedures made also possible to verify the relative efficiency of each fund leading to the conclusion that there was a loss of efficiency in a significant part of the industry; 28 became less efficient, 12 did not present changes worthy of mention, and only 4 increased their levels of efficiency. In addition, the results obtained with the use of the various models bring about different possibilities of analysis and can contribute to the decision-making by portfolio managers and investors in the capital market.

Insectes, monstres et esprits
Authors: Guédon Marie-Françoise 
Published: July 2018

Les Athapascans de l’Alaska et du Nord-Ouest canadien utilisent les mêmes termes pour désigner d’une part les insectes et tout ce qui grouille et, d’autre part, les monstres aquatiques ou nocturnes, les géants mythiques, les esprits et les fantômes, ainsi que les gens-des-bois, êtres sauvages qui hantent la forêt subarctique. À première vue, il est difficile de trouver, entre ces diverses créatures, un lien qui justifierait une taxonomie aussi ambiguë, même en tenant compte des particularités des systèmes de classification athapascans. Une comparaison des créatures en question révèle des indices inattendus qui permettent une hypothèse : toutes ces créatures entretiennent un lien avec l’espace chamanique et mythique (ink’on), y compris les insectes qui feraient déjà directement partie de cet espace parce qu’ils étaient présents au début des temps mythiques, avant l’émergence de l’humanité. Des études linguistiques pourraient confirmer le lien sémantique entreink’onet insectes.

Une métamorphose des discours : le Québec et la géographie
Authors: CLAVAL Paul 
Published: July 2018

Importée de France dans les années 1930, en contact permanent avec les géographies britannique et américaine, l’étude de la terre est dominée au Québec par deux soucis : celui d’expliquer les formes que revêt, et qu’a revêtues, l’organisation de l’espace dans la vallée du Saint-Laurent (et ailleurs), et celui de comprendre la permanence du fait français dans cette partie du monde. Le premier souci explique que la recherche y ait connu, depuis un demi-siècle, les mêmes mutations que dans le reste du monde occidental. Le second, d’abord prédominant, a vu son champ se réduire au domaine culturel, mais explique sans doute l’inventivité et la liberté de ton des chercheurs. La globalisation se traduit par l’élargissement des espaces qu’ils étudient, et par l’attention accrue qu’ils portent aux problèmes sociaux, culturels et environnementaux du monde actuel.
Des paysages, des idées et des hommes : le projet collectif de Charlevoix 1
Authors: BUREAU Luc 
Published: July 2018

D’une façon quelque peu empirique, on peut distinguer quatre phases intereliées dans le processus de formation de l’image collective d’un milieu : l’identification, la modélisation, la signification et l’affectivité. Partant de ces composantes fondamentales de l’activité perceptuelle, et les mettant elles-mêmes en relation avec celles du paysage (les formes, les habitants et les valeurs), il nous a été possible de reconstituer la trame du projet collectif de Charlevoix et d’en reconnaître le niveau de consistance dans le temps et dans l’espace. Essentiellement polydimensionnel et ouvert dans le passé lointain, ce « projet » semble se contracter au fur et à mesure que l’on progresse dans le temps : l’éventail de choix se referme, en imposant des comportements de plus en plus stéréotypés. Débordant le cadre du passé et du présent, on en arrive à anticiper le profil du « nouveau projet collectif » qui s’articule, non pas en prévision d’un retour à la polyvalence ancienne, mais en fonction d’une nouvelle conception du développement, cherchant à introduire les idées de planification, de participation collective et de protection du milieu.
Herbivorous protist growth and grazing rates at in situ and artificially elevated temperatures during an Arctic phytoplankton spring bloom
Authors: Menden-Deuer Susanne , Lawrence Caitlyn , Franzè Gayantonia 
Published: July 2018

To assess protistan grazing impact and temperature sensitivity on plankton population dynamics, we measured bulk and species-specific phytoplankton growth and herbivorous protist grazing rates in Disko Bay, West Greenland in April-May 2011. Rate estimates were made at three different temperatures in situ (0 °C), +3 °C and +6 °C over ambient. In situ Chlorophylla(Chla) doubled during the observation period to ∼12 µg ChlaL−1, with 60–97% of Chlain the >20 µm size-fraction dominated by the diatom genusChaetoceros.Herbivorous dinoflagellates comprised 60–80% of microplankton grazer biomass. At in situ temperatures, phytoplankton growth or grazing by herbivorous predators <200 µm was not measurable until 11 days after observations commenced. Thereafter, phytoplankton growth was on average 0.25 d−1. Phytoplankton mortality due to herbivorous grazing was only measured on three occasions but the magnitude was substantial, up to 0.58 d−1. Grazing of this magnitude removed ∼100% of primary production. In short-term temperature-shift incubation experiments, phytoplankton growth rate increased significantly (20%) at elevated temperatures. In contrast, herbivorous protist grazing and species-specific growth rates decreased significantly (50%) at +6 °C. This differential response in phytoplankton and herbivores to temperature increases resulted in a decrease of primary production removed with increasing temperature.Phaeocystisspp. abundance was negatively correlated with bulk grazing rate. Growth and grazing rates were variable but showed no evidence of an inherent, low temperature limitation. Herbivorous protist growth rates in this study and in a literature review were comparable to rates from temperate waters. Thus, an inherent physiological inhibition of protistan growth or grazing rates in polar waters is not supported by the data. The large variability between lack of grazing and high rates of primary production removal observed here and confirmed in the literature for polar waters implies larger amplitude fluctuations in phytoplankton biomass than slower, steady grazing losses of primary production.
Breaking the Limits of Ionic Liquid‐Based Supercapacitors: Mesoporous Carbon Electrodes Functionalized with Manganese Oxide Nanosplotches for Dense, Stable, and Wide‐Temperature Energy Storage

Published: July 2018

AbstractManganese oxide (MnO2) nanosplotches (NSs) are deposited on N‐ and S‐doped ordered mesoporous carbon (N,S‐CMK‐3) essentially blocking microporosity. The obtained N,S‐CMK‐3/MnO2 composite materials are assembled into ionic liquid (IL)‐based symmetric supercapacitors, which exhibit a high specific capacitance of 200 F g−1 (0–3.5 V) at a scan rate of 2 mV s−1, and good rate stability with 55.5% capacitance retention at a scan rate of 100 mV s−1. The device can operate in a wide temperature range (−20 to 60 °C), and high cycling stability of N,S‐CMK‐3/MnO2 composite electrode is demonstrated. Lower energy of −3.56 eV can be achieved for the adsorption of 1‐ethyl‐3‐methylimidazolium+ (EMIM+) cation on the edge between MnO2 NSs and N,S‐CMK‐3 than on the plane of MnO2 NS (−3.04 eV), both being more preferred than the surface of pristine N,S‐CMK‐3 (−1.52 eV). This strengthening of the ion adsorption at the three‐phase boundary between N,S‐CMK‐3, MnO2, and IL leads to enhancement of the specific capacity as compared to nondoped or MnO2‐free reference materials. Supercapacitors based on such composite electrodes show significantly enhanced areal capacity pointing to energy storage in the mesopores rather than in the electrochemical surface layer, demonstrating a new energy storage mechanism in ILs.
Recent Advances in Tracking the Transplanted Stem Cells Using Near‐Infrared Fluorescent Nanoprobes: Turning from the First to the Second Near‐Infrared Window

Published: July 2018

AbstractStem cell‐based regenerative medicine has attracted tremendous attention for its great potential to treat numerous incurable diseases. Tracking and understanding the fate and regenerative capabilities of transplanted stem cells is vital for improving the safety and therapeutic efficacy of stem cell‐based therapy, therefore accelerating the clinical application of stem cells. Fluorescent nanoparticles (NPs) have been widely used for in vivo tracking of the transplanted stem cells. Among these fluorescent NPs, near‐infrared (NIR) NPs have greatly improved the sensitivity, tissue penetration depth, spatial and temporal resolutions of the fluorescence imaging‐based stem cell tracking technologies due to the reduced absorption, scattering, and autofluorescence of NIR fluorescence in tissues. Here, this review summarizes the recent studies regarding the tracking of transplanted stem cells using NIR NPs and emphasizes the recent advances of fluorescence imaging in the second NIR window (NIR‐II, 1000–1700 nm). Furthermore, the challenges and future prospects of the NIR NP‐based technologies are also discussed.
