Fragmented Comet 73P/Schwassmann–Wachmann 3
Authors: Graykowski Ariel , Jewitt and David 
Published: August 2019

Abstract
Comet 73P/Schwassmann–Wachmann 3 has been observed to fragment on several occasions, yet the cause of its fragmentation remains poorly understood. We use previously unpublished archival Hubble Space Telescope data taken in 2006 to study the properties of the primary fragment, 73P-C, in order to constrain the potential fragmentation mechanisms. Currently the literature presents a wide range of measured rotational periods, some of which suggest that the nucleus might have split due to rotational instability. However, we find the most likely value of the rotation period to be 10.38 ± 0.04 hr (20.76 ± 0.08 hr if double-peaked), much longer than the critical period for rotational instability for any reasonable nucleus density and shape, even in the absence of tensile strength. We also find strong, cyclic photometric variations of about 0.31 ± 0.01 mag in the central light from this object, while similar variations with a smaller range are apparent in the surrounding dust coma. These observations are compatible with rotational modulation of the mass-loss rate and with dust having a mean outflow speed of 107 ± 9 m s−1. Finally, we also estimate the radius of the nucleus to be 0.4 ± 0.1 km accounting for dust contamination and assuming a geometric albedo of 0.04.
Solar Image Restoration with the CycleGAN Based on Multi-fractal Properties of Texture Features
Authors: Jia Peng , Huang Yi , Cai Bojun , Cai Dongmei 
Published: August 2019

Abstract
Texture is one of the most obvious characteristics in solar images and it is normally described by texture features. Because textures from solar images of the same wavelength are similar, we assume that texture features of solar images are multi-fractals. Based on this assumption, we propose a pure data-based image restoration method: with several high-resolution solar images as references, we use the Cycle-Consistent Adversarial Network to restore blurred images of the same steady physical process, in the same wavelength obtained by the same telescope. We test our method with simulated and real observation data and find that our method can improve the spatial resolution of solar images, without loss of any frames. Because our method does not need a paired training set or additional instruments, it can be used as a post-processing method for solar images obtained by either seeing-limited telescopes or telescopes with ground-layer adaptive optic systems.
Heuristic Description of Perpendicular Diffusion of Energetic Particles in Astrophysical Plasmas
Authors: Shalchi A.

Abstract
A heuristic approach for collisionless perpendicular diffusion of energetic particles is presented. Analytic forms for the corresponding diffusion coefficient are derived. The heuristic approach presented here explains the parameter a
2 used in previous theories in order to achieve agreement with simulations and its relation to collisionless Rechester & Rosenbluth diffusion. The obtained results are highly relevant for applications because previously used formulas are altered significantly in certain situations.
Giant Squamous Cell Carcinoma on Chronic Lichen Planus on the Ankle - A Case Report and Short Literature Review
Authors: Wollina Uwe , Krönert Claudia , Schönlebe Jacqueline , Vojvodic Aleksandra , Lotti Torello 
Published: August 2019

BACKGROUND: Cutaneous squamous cell carcinoma (SCC) is the second most common malignancy of skin. Although a major risk factor is a chronic exposure to ultraviolet radiation, preexistent chronic inflammatory disorders may also possess an increased risk for SCC. That is not the case for cutaneous lichen planus in contrast to oral lichen planus and oral SCC.
CASE REPORT: We report the case of an 87-year-old Caucasian woman presenting with a giant verrucous tumour on the left ankle. She suffered from long-standing disseminated lichen planus. Histology confirmed the diagnosis of SCC on partly verrucous lichen planus. The course was complicated due to sepsis. An emergency transfemoral amputation became necessary. The patients survived and could be released into her nursery. A literature review underlined the rarity of SCC on lichen planus of the skin. Most of these rare cases were in patients in their second half of life on the lower legs. Hypertrophic lichen plnaus was overrepresented.
CONCLUSIONS: Although very rare by number, SCC can complicate lichen planus and lead to the life-threatening situation. Atypical verrucous lesions on lichen planus warrant a histologic analysis. Surgery is the treatment of choice for cutaneous SCC.
Genetic and epigenetic regulation of phenotypic variation in invasive plants – linking research trends towards a unified framework
Authors: Banerjee Achyut Kumar , Guo Wuxia , Huang Yelin 
Published: August 2019

Phenotypic variation in the introduced range of an invasive species can be modified by genetic variation, environmental conditions and their interaction, as well as stochastic events like genetic drift. Recent studies found that epigenetic modifications may also contribute to phenotypic variation being independent of genetic changes. Despite gaining profound ecological insights from empirical studies, understanding the relative contributions of these molecular mechanisms behind phenotypic variation has received little attention for invasive plant species in particular.
This review therefore aimed at summarizing and synthesizing information on the genetic and epigenetic basis of phenotypic variation of alien invasive plants in the introduced range and their evolutionary consequences. Transgenerational inheritance of epigenetic modifications was highlighted focusing on its influence on microevolution of the invasive plant species. We presented a comprehensive account of epigenetic regulation of phenotypic variation and its role in plant invasion in the presence of reduced standing genetic variation, inbreeding depression and associated genomic events which have often been observed during introduction and range expansion of an invasive alien species. Finally, taking clues from the studies conducted so far, we proposed a unified framework of future experimental approaches to understand ecological and evolutionary aspects of phenotypic variation. This holistic approach, being aligned to the invasion process in particular (introduction-establishment-spread), was intended to understand the molecular mechanisms of phenotypic variation of an invasive species in its introduced range and to disentangle the effects of standing genetic variation and epigenetic regulation of phenotypic variation.
La productivité globale des facteurs : comment évaluer plus précisément « notre ignorance » ?
Authors: Daw Georges 
Published: August 2019

Cet article traite du thème de la comptabilité de la croissance économique appliquée à la France. Exercice rétrospectif (pouvant revêtir une dimension prospective), celui-ci cherche à savoir quels auront été les poids des déterminants de la croissance. Dans sa version usuelle, ce cadre a de nombreux mérites mais ne permet pas toutefois d’aspirer à une détermination quantitative exhaustive des sources de la croissance. Cela est d’autant plus vrai que des hypothèses pourtant empiriquement plausibles que nous développons successivement puis cumulativement n’y sont pas considérées. Le poids de ces sources se retrouve alors fatalement dans le « résidu de Solow », mesurant « notre ignorance », mésestimant ainsi les véritables leviers de croissance. Cette contribution d’ordre économique, méthodologique et statistique portera sur l’année 2015 à titre illustratif. Le cadre comptable usuel ainsi complété, évalué et réplicable spatio-temporellement, y compris prospectivement, fournit un modèle d’analyse et de comptabilité raffinée de la croissance économique révélant l’obtention de contributions factorielles et de résidus de croissance différents de ceux que la pratique courante de la comptabilité de la croissance aurait fournis.

Aides publiques à l’efficacité énergétique
Authors: Quirion Philippe , Giraudet Louis-Gaëtan 
Published: August 2019

En France, les subventions à l’efficacité énergétique sont nombreuses et variées. La plupart sont de type ad valorem – proportionnelles au prix du bien ou service ciblé, comme le Crédit d’impôt pour la transition énergétique (CITE), la TVA à taux réduit pour la rénovation thermique des bâtiments, l’éco-prêt à taux zéro (éco-PTZ) et les aides de l’Agence nationale pour l’amélioration de l’habitat (ANAH). D’autres sont de type « spécifiques » c’est-à-dire indépendantes du prix de vente : le bonus automobile et le dispositif des certificats d’économie d’énergie. Nous fournissons une revue des arguments en faveur de chacun des deux types de subventions. Par rapport aux subventions spécifiques, les subventions ad valorem présentent quatre inconvénients : elles génèrent plus de dépenses publiques, distordent la qualité des biens, profitent davantage aux ménages les plus aisés et incitent davantage à la fraude. Cependant, les subventions spécifiques ne sont pas non plus sans défaut : la base fiscale doit être définie spécifiquement pour chaque type de bien et en cas de baisse inattendue du coût de production du bien subventionné, le prix de ce dernier risque de devenir quasiment nul.

Abstract
Neutrophils are abundant circulating leukocytes that are rapidly recruited to sites of inflammation in an integrin-dependent fashion. Contrasting with the well-characterized regulation of integrin activation, mechanisms regulating integrin inactivation remain largely obscure. Using mouse neutrophils, we demonstrate in this study that the GTPase activating protein ARAP3 is a critical regulator of integrin inactivation; experiments with Chinese hamster ovary cells indicate that this is not restricted to neutrophils. Specifically, ARAP3 acts in a negative feedback loop downstream of PI3K to regulate integrin inactivation. Integrin ligand binding drives the activation of PI3K and of its effectors, including ARAP3, by outside-in signaling. ARAP3, in turn, promotes localized integrin inactivation by negative inside-out signaling. This negative feedback loop reduces integrin-mediated PI3K activity, with ARAP3 effectively switching off its own activator, while promoting turnover of substrate adhesions. In vitro, ARAP3-deficient neutrophils display defective PIP3 polarization, adhesion turnover, and transendothelial migration. In vivo, ARAP3-deficient neutrophils are characterized by a neutrophil-autonomous recruitment defect to sites of inflammation.
Corrosion in CO2 Systems with Impurities Creating Strong Acids
Authors: Morland Bjørn H. , Tjelta Morten , Dugstad Arne , Svenningsen Gaute 
Published: August 2019

There are several proposed specifications for CO2 transport regarding how much impurities that can be allowed in the CO2 stream. Many of these specifications are based on health, safety, and environment (HSE) considerations in case of accidental spill, and only limited focus has been on the pipeline integrity. Previous work has demonstrated that many of the impurities that are expected to be present in CO2 captured from flue gasses may react and form corrosive species. The present paper studied impurity reactions and corrosion under simulated transport conditions (25°C and 10 MPa of CO2). An experiment was performed in a transparent autoclave which allowed for in situ visual observation. Chemical reactions between the impurities were observed even at very low concentrations (<100 ppmv). These reactions contributed to the production of nitric and sulfuric acid together with formation of elemental sulfur. Corrosion was observed on coupons of carbon steel, but not on stainless steels. The corrosion rate of carbon steel was low, but the amount of acids and solids (corrosion products) produced cannot be accepted from a pipeline integrity perspective. Further experimental studies are needed to determine specific limits for impurity concentrations in captured CO2 for transport.

Published: August 2019

AbstractOBJECTIVE. Our objective was to identify perceived barriers and strategies to improve primary care encounters, as reported by adults with autism spectrum disorder (ASD), caregivers of adults with ASD, and primary care providers (PCPs) treating adults with ASD.METHOD. As part of a larger mixed-methods design, adults with ASD, caregivers, and PCPs (N = 78) in Los Angeles and Philadelphia completed surveys examining barriers to care and strategies to improve care.RESULTS. Multiple barriers to care were reported by adults with ASD and caregivers, including communication and sensory challenges. Adults with ASD and caregivers reported minimal use of strategies during primary care visits but indicated that those used were helpful during care. Expert PCPs reported using strategies more frequently than novice PCPs. All respondent groups endorsed that strategies had the potential to improve care in the future for adults with ASD.CONCLUSION. Opportunities exist for occupational therapy collaboration in primary health care and primary care education to improve care for adults with ASD.
The Parcels v2.0 Lagrangian framework: new field interpolation schemes
Authors: Delandmeter Philippe , van Sebille Erik 
Published: August 2019

Abstract. With the increasing number of data produced by numerical ocean models, so increases the need for efficient tools to analyse these data. One of these tools is Lagrangian ocean analysis, where a set of virtual particles is released and their dynamics are integrated in time based on fields defining the ocean state, including the hydrodynamics and biogeochemistry if available. This popular methodology needs to adapt to the large variety of models producing these fields at different formats. This is precisely the aim of Parcels, a Lagrangian ocean analysis framework designed to combine (1) a wide flexibility to model particles of different natures and (2) an efficient implementation in accordance with modern computing infrastructure. In the new Parcels v2.0, we implement a set of interpolation schemes to read various types of discretized fields, from rectilinear to curvilinear grids in the horizontal direction, from z to s levels in the vertical direction and using grid staggering with the Arakawa A, B and C grids. In particular, we develop a new interpolation scheme for a three-dimensional curvilinear C grid and analyse its properties. Parcels v2.0 capabilities, including a suite of meta-field objects, are then illustrated in a brief study of the distribution of floating microplastic in the northwest European continental shelf and its sensitivity to various physical processes.
n. 24 - AVALIAÇÃO DAS POLÍTICAS DE EXPANSÃO E DE RESERVA DE VAGAS NA REDE FEDERAL DE ENSINO SUPERIOR: UNIFESP EM ANÁLISE
Authors: Pedra Minhoto Maria Angélica , Benedicto Giglio Celia Maria 
Published: August 2019

Este trabalho tem como objetivo realizar uma avaliação do processo de implementação das políticas de expansão e de reserva de vagas na rede federal de ensino superior brasileira, verificando os efeitos da adesão ao Reuni e o estabelecimento da Lei de Cotas na Universidade Federal de São Paulo (Unifesp). Para tanto, apresenta inicialmente o contexto nacional de evolução das matrículas na educação superior e dados do perfil socioeconômico dos discentes das instituições federais de ensino superior, produzidos pelo Fórum Nacional de Pró-Reitores de Assuntos Estudantis. Na sequência, mostra o crescimento dos cursos de graduação da Unifesp, sua política institucional de reserva de vagas, além do histórico e análise do perfil socioeconômico e cultural de seu ingressantes, entre os anos de 2012 e 2016. Constatou-se que, ainda que imprescindível, a política de reserva de vagas não tem sido suficiente para democratizar mais amplamente o acesso à formação de qualidade da universidade pública em todas as carreiras. No caso da Unifesp, o caminho mais consistente para o crescimento da diversidade e inclusão de um novo perfil de estudante na instituição foi a expansão no número de carreiras, com ampliação do número de vagas.

The Opacity of a Multinational Company’s Organization, Legal Structure and Power
This article describes the types of information that a multinational company must make public pursuant to Book 2 of the Dutch Civil Code, the Act on Financial Supervision and the Commercial Registers Act. We ascertain that: (i) the Dutch Trade Register fails in providing adequate information about the foreign parts of a group; (ii) the annual reporting laws fail to require companies to provide an insight in the group legal structure, the business organization and the corporate social responsibility profile of a multinational company; and (iii) the Act on Financial Supervision fails to include disclosure requirements regarding the corporate social responsibility profile of a listed company. Different possible legislative amendments are provided in this article that could enhance transparency concerning a Dutch multinational company’s business organization, the legal structure and its corporate social responsibility profile, so that corporate information is better accessible for stakeholders. We conclude that most of these improvements are not limited to the Dutch legal system, but can be seen in the light of a global trend of increased corporate transparency. With this article, we hope to contribute to a new mind-set whereby transparency is stimulated, by offering concrete (policy) tools.

The OECD Guidelines for Multinational Enterprises on Responsible Business Conduct: Soft Law with Hard Consequences
OECD Guidelines for Multinational Enterprises are the most comprehensive international public standard on all areas of CSR with 46 adherent governments. The unique feature of the Guidelines is its grievance mechanism. The National Contact Points for the OECD Guidelines serve as a complaints and problem solving mechanism for trade unions and NGO’s related to for example human rights and labor standards. Since 2011 the Guidelines apply not only to investments but also to global supply chains. The concept of CSR Due Diligence in the supply chains is now a key pillar of CSR.

Better Access to Remedy in Company-Community Conflicts in the Field of CSR: A Model for Company-Based Grievance Mechanisms
The Special Representative to the UN Secretary-General on human rights and transnational corporations and other business enterprises, John Ruggie, establishes access to remedy as one of the three pillars of the UN ‘Protect, Respect, Remedy’ Framework. In this Framework, Ruggie prescribes that company-based grievance mechanisms can be one effective means of enabling remediation to those potentially being impacted by business enterprises’ activities. This report proposes a model for company-based grievance mechanisms that follow a combination of interest-based and rights-compatible approaches to conflict resolution of all corporate social responsibility issues in company–stakeholder relationships.
