Abstract
The Astropy Project supports and fosters the development of open-source and openly developed Python packages that provide commonly needed functionality to the astronomical community. A key element of the Astropy Project is the core package astropy, which serves as the foundation for more specialized projects and packages. In this article, we provide an overview of the organization of the Astropy project and summarize key features in the core package, as of the recent major release, version 2.0. We then describe the project infrastructure designed to facilitate and support development for a broader ecosystem of interoperable packages. We conclude with a future outlook of planned new features and directions for the broader Astropy Project.

Abstract
In this paper, the high-precision light curves of the Kepler target KIC 5950759 are analyzed. The Fourier analysis of the long cadence (LC) light curve reveals three independent frequencies. Two of them are main pulsation modes: F0 = 14.221373(21) d−1 and F1 = 18.337249(44) d−1. The third independent frequency, f

m
= 0.3193 d−1, is found in LC data with a signal-to-noise ratio of 6.2. A weak modulation of f

m
to F0 and F1 modes (triplet structures centered on F0 and F1) are detected both in long and short cadence data. This is the first detection of the modulation effect in a double-mode high-amplitude δ Scuti (HADS) star. The most possible cause of the modulation effect in the light curves is amplitude modulation with the star’s rotation frequency of 0.3193 d−1. The preliminary analysis suggests that KIC 5950759 is in the bottom of the HADS instability strip and likely situated in the main sequence. Spectroscopic observations are necessary to verify the true nature of the modulation terms.
Two Kinds of Dynamic Behavior in a Quiescent Prominence Observed by the NVST

Published: August 2018

Abstract
We present high-resolution observations of two kinds of dynamic behavior in a quiescent prominence using the New Vacuum Solar Telescope, i.e., Kelvin–Helmholtz instabilities (KHIs) and small-scale oscillations. The KHIs were identified as rapidly developed vortex-like structures with counterclockwise/clockwise rotations in the Hα red-wing images at +0.3 Å, which were produced by the strong shear-flow motions on the surface/interface of prominence plumes. The KHI growth rates are estimated to be ∼0.0135 ± 0.0004 and ∼0.0138 ± 0.0004. Our observational results further suggest that the shear velocities (i.e., supersonic) of the mass flows are fast enough to produce the strong deformation of the boundary and overcome the restraining surface tension force. This flow-driven instability might play a significant role in the process of plasma transfer in solar prominences. The small-scale oscillations perpendicular to the prominence threads are observed in the Hα line-center images. The oscillatory periods changed nonmonotonically and showed two changing patterns, in which one first decreased slowly and then started to increase, while the other grew fast at the beginning and then started to decrease. Both of these thread oscillations with changing periods were observed to be unstable for an entire cycle, and they were local in nature. All our findings indicate that the small-scale thread oscillations could be magnetohydrodynamic waves in the solar corona.

Abstract
Sigma clipping is commonly used in astronomy for outlier rejection, but the number of standard deviations beyond which one should clip data from a sample ultimately depends on the size of the sample. Chauvenet rejection is one of the oldest, and simplest, ways to account for this, but, like sigma clipping, it depends on the sample’s mean and standard deviation, neither of which are robust quantities: both are easily contaminated by the very outliers they are being used to reject. Many, more robust measures of central tendency, and of sample deviation, exist, but each has a trade-off with precision. Here we demonstrate that outlier rejection can be both very robust and very precise if decreasingly robust but increasingly precise techniques are applied in sequence. To this end, we present a variation on Chauvenet rejection that we call “robust” Chauvenet rejection (RCR), which uses three decreasingly robust/increasingly precise measures of central tendency and four decreasingly robust/increasingly precise measures of sample deviation. We show this sequential approach to be very effective for a wide variety of contaminant types, even when a significant—even dominant—fraction of the sample is contaminated, and especially when the contaminants are strong. Furthermore, we have developed a bulk-rejection variant, to significantly decrease computing times, and RCR can be applied both to weighted data and when fitting parameterized models to data. We present aperture photometry in a contaminated, crowded field as an example. RCR may be used by anyone at https://skynet.unc.edu/rcr, and source code is available there as well.
SYGMA: Stellar Yields for Galactic Modeling Applications

Published: August 2018

Abstract
The Stellar Yields for Galactic Modeling Applications (SYGMA) code is an open-source module that models the chemical ejecta and feedback of simple stellar populations (SSPs). It is intended for use in hydrodynamical simulations and semi-analytic models of galactic chemical evolution. The module includes the enrichment from asymptotic giant branch (AGB) stars, massive stars, Type Ia supernovae (SNe Ia), and compact binary mergers. An extensive and extendable stellar yields library includes the NuGrid yields with all elements and many isotopes up to Bi. Stellar feedback from mechanic and frequency-dependent radiative luminosities are computed based on NuGrid stellar models and their synthetic spectra. The module further allows for customizable initial mass functions and SN Ia delay-time distributions to calculate time-dependent ejecta based on stellar yield input. A variety of r-process sites can be included. A comparison of SSP ejecta based on NuGrid yields with those from Portinari et al. and Marigo reveals up to factors of 3.5 and 4.8 less C and N enrichment from AGB stars at low metallicity, a result we attribute to NuGrid’s modeling of hot-bottom burning. Different core-collapse supernova explosions and fallback prescriptions may lead to substantial variations for the accumulated ejecta of C, O and Si in the first 107 years at Z = 0.001. An online interface of the open-source SYGMA module enables interactive simulations, analysis, and data extraction of the evolution of all species formed by the evolution of simple stellar populations.
Justiciers amateurs et croisades morales en Russie contemporaine
Authors: Favarel-Garrigues Gilles 
Published: August 2018

Résumé Depuis le début des années 2010, les entrepreneurs de morale désireux de faire respecter la loi et de rendre la justice se multiplient en Russie où ils défendent les causes les plus diverses. Ils se filment en train d’agir en justiciers autoproclamés et bénéficient d’une notoriété parfois importante sur les réseaux sociaux. En quoi l’engagement de ces justiciers amateurs défie-t-il les pouvoirs publics ? L’article présente ces pratiques d’auto-justice, s’interroge sur la pertinence du concept de vigilantisme pour les décrire et montre qu’elles font l’objet d’un traitement différentiel de la part des pouvoirs publics.
Entre alliances et métriques

Published: August 2018

Résumé Cet article étudie les dynamiques de débat dans le champ institutionnel global des politiques de protection de la biodiversité. Il analyse les processus d’alliances et d’enrôlements qui s’y jouent entre organisations non gouvernementales de conservation, acteurs académiques (écologues puis économistes) et organisations internationales publiques. Il montre ainsi combien le débat est conditionné et spécifiquement orienté par la construction de bases de données, métriques et indicateurs sur la biodiversité. Initialement construit autour de l’idée de conservation d’espaces et d’espèces remarquables, le débat s’est élargi et enrichi dans les dernières décennies à partir de la notion de services écosystémiques. Pour autant, les politiques publiques globales restent organisées autour d’un instrument central : les aires protégées.
Spirituele vorming om ’n missionale karakter in gemeentes in die praktyk te bewerkstellig

Published: August 2018

Spiritual formation to bring about a missional character in congregations in practice. This study applied literature review to focus on missional ecclesiology and, more specifically, on the important role and impact of spirituality in supporting a missional church. Although the research originated in reformed churches in South Africa, the reflection on the relation between the concept of missional church and a Christian spirituality, and the practical examples that illustrate such a missional spirituality, transcend the context and is applicable to most contexts. The conclusion of the research affirmed a Trinitarian approach to spirituality and the indispensable place of a missional spirituality for Christian congregations. A life in the Trinity forms and informs everyday life. It encourages disciples of Christ to participate in God’s mission. There is no difference between Christian spirituality and missional spirituality. One of the key findings was the important role of habits: believers should change their habits in their everyday life in order to change their thoughts, and not the other way around. Practical examples of habits are as follows: systematic reading of God’s Word; to see what God sees; kenosis shown through hospitality; faith discernment with other believers; associating the everyday normalities as spiritual; finding rest in God; and eating together.Intradisciplinary and/or Interdisciplinary implications: This article was written from the perspective of mission studies. The contextual challenge was to emphasise the importance of habits in Christian spirituality, and the reciprocal relationship between spirituality and being a missional church. This article has challenged the culture of church-organised mission projects.

Modeling study of impacts on surface ozone of regional transport and emissions reductions over North China Plain in summer 2015
Authors: Han Xiao , Zhu Lingyun , Wang Shulan , Meng Xiaoyan , Zhang Meigen , Hu Jun 
Published: August 2018

Abstract. Tropospheric ozone (O3) has replaced PM2.5 or PM10 as the
primary pollutant in the North China Plain (NCP) during summer in recent
years. A comprehensive understanding of O3 production in response
to the reduction of precursor emissions over the NCP is urgently demanded for
effective control policy design. In this study, the air quality modeling
system RAMS-CMAQ (Regional Atmospheric Modeling System–Community Multiscale
Air Quality), coupled with the ISAM (Integrated Source Apportionment Method)
module is applied to investigate the O3 regional transport and source
contribution features during a heavy O3 pollution episode in June 2015
over the NCP. The results show that emissions sources in Shandong and Hebei
were the major contributors to O3 production in the NCP. Not only the
highest local contribution of O3 mass burden but also more than 30 %
contribution of O3 mass burdens in Beijing and Tianjin came from
the emissions sources in these two provinces, respectively. Conversely,
the urban areas and most O3-polluted regions of the NCP were mainly
dominated by conditions sensitive to volatile organic compounds, while “both control” and
NOx-sensitive conditions dominated the suburban and remote areas,
respectively. Then, based on the sensitivity tests, the effects of several
hypothetical scenarios of emissions control on reducing the O3 pollution
were compared and discussed. The results indicated that the emissions control
of industry and residential sectors was the most efficient method if the
emissions reduction percentage was higher than 40 %. However, when the
emissions reduction percentage dropped below 30 %, the power plant sector
could make significant contributions to the decrease in O3. The control
strategies should be promptly adjusted based on the emissions reduction, and
the modeling system can provide valuable information for precisely choosing
the emissions sector combination to achieve better efficiency.
Basic and extensible post-processing of eddy covariance flux data with REddyProc

Published: August 2018

Abstract. With the eddy covariance (EC) technique, net fluxes of carbon dioxide (CO2) and other trace gases as well as water and energy fluxes can be measured at the ecosystem level. These flux measurements are a main source for understanding biosphere–atmosphere interactions and feedbacks through cross-site analysis, model–data integration, and upscaling. The raw fluxes measured with the EC technique require extensive and laborious data processing. While there are standard tools1 available in an open-source environment for processing high-frequency (10 or 20 Hz) data into half-hourly quality-checked fluxes, there is a need for more usable and extensible tools for the subsequent post-processing steps. We tackled this need by developing the REddyProc package in the cross-platform language R that provides standard CO2-focused post-processing routines for reading (half-)hourly data from different formats, estimating the u* threshold, as well as gap-filling, flux-partitioning, and visualizing the results. In addition to basic processing, the functions are extensible and allow easier integration in extended analysis than current tools. New features include cross-year processing and a better treatment of uncertainties. A comparison of REddyProc routines with other state-of-the-art tools resulted in no significant differences in monthly and annual fluxes across sites. Lower uncertainty estimates of both u* and resulting gap-filled fluxes by 50 % with the presented tool were achieved by an improved treatment of seasons during the bootstrap analysis. Higher estimates of uncertainty in daytime partitioning (about twice as high) resulted from a better accounting for the uncertainty in estimates of temperature sensitivity of respiration. The provided routines can be easily installed, configured, and used. Hence, the eddy covariance community will benefit from the REddyProc package, allowing easier integration of standard post-processing with extended analysis. 1http://fluxnet.fluxdata.org/2017/10/10/toolbox-a-rolling-list-of-softwarepackages-for-flux-related-data-processing/, last access: 17 August 2018

Published: August 2018

Introduction:
A surgical simulation platform has been developed to simulate fluoroscopically guided surgical procedures by coupling computer modeling with a force-feedback device as a training tool for orthopaedic resident education in an effort to enhance motor skills and potentially minimize radiation exposure. The objective of this study was to determine whether the simulation platform can distinguish between novice and experienced practitioners of percutaneous pinning of hip fractures.

Methods:
Medical students, orthopaedic residents, orthopaedic trauma fellows, and attending surgeons completed in situ hip-pinning simulation that recorded performance measures related to surgical accuracy, time, and use of fluoroscopy. Linear regression models were used to compare the association between performance and practitioner experience.

Results:
Notable associations were shown between performance and practitioner experience in 10 of the 15 overall measures (P < 0.05) and 9 of 11 surgical accuracy parameters (P < 0.05).

Conclusion:
This novel simulation platform can distinguish between novice and experienced practitioners and defines a performance curve for completion of simulated in situ hip pinning. This important first step lays the groundwork for subsequent validation studies, which will seek to demonstrate the efficacy of this simulator in improving clinical performance by trainees completing a sequence of skills-training modules.

Published: August 2018

Introduction:
The nature of trampoline injuries may have changed with the increasing popularity of recreational jump parks.

Methods:
A retrospective review was performed evaluating domestic trampoline and commercial jump park injuries over a 2-year period.

Results:
There were 439 trampoline injuries: 150 (34%) at jump parks versus 289 (66%) on home trampolines. Fractures and dislocations accounted for 55% of jump park injuries versus 44% of home trampoline injuries. In adults, fractures and dislocations accounted for 45% of jump park injuries versus 17% of home trampoline injuries. More lower extremity fractures were seen at jump parks versus home trampolines in both children and adults. Adults had a 23% surgical rate with jump park injuries versus a 10% surgical rate on home trampolines.

Discussion:
Trampoline-related injury distribution included a higher percentage of fractures/dislocations, lower extremity fractures, fractures in adults, and surgical interventions associated with jump parks versus home trampolines.
