Abstract
Comparison analyses between the gas emission data (

line and

line) and the Planck/IRAS dust emission data (optical depth at

and dust temperature

) allow us to estimate the amount and distribution of the hydrogen gas more accurately, and our previous studies revealed the existence of a large amount of optically thick

gas in the solar neighborhood. Referring to this, we discuss the neutral hydrogen gas around the Perseus cloud in the present paper. By using the J-band extinction data, we found that

increases as a function of the 1.3th power of column number density of the total hydrogen (

), and this implies dust evolution in high density regions. This calibrated

relationship shows that the amount of the

gas can be underestimated to be

if the optically thin

method is used. Based on this relationship, we calculated the optical depth of the

line (

) and found that

around the molecular cloud. The effect of

is still significant, even if we take into account the dust evolution. We also estimated a spatial distribution of the

conversion factor (

), and we found its average value is

. Although these results are inconsistent with some previous studies, these discrepancies can be well explained by the difference of the data and analyses methods.
Multi-viewpoint Coronal Mass Ejection Catalog Based on STEREO COR2 Observations

Published: April 2017

Abstract
We present the first multi-viewpoint coronal mass ejection (CME) catalog. The events are identified visually in simultaneous total brightness observations from the twin SECCHI/COR2 coronagraphs on board the Solar Terrestrial Relations Observatory mission. The Multi-View CME Catalog differs from past catalogs in three key aspects: (1) all events between the two viewpoints are cross-linked, (2) each event is assigned a physics-motivated morphological classification (e.g., jet, wave, and flux rope), and (3) kinematic and geometric information is extracted semi-automatically via a supervised image segmentation algorithm. The database extends from the beginning of the COR2 synoptic program (2007 March) to the end of dual-viewpoint observations (2014 September). It contains 4473 unique events with 3358 events identified in both COR2s. Kinematic properties exist currently for 1747 events (26% of COR2-A events and 17% of COR2-B events). We examine several issues, made possible by this cross-linked CME database, including the role of projection on the perceived morphology of events, the missing CME rate, the existence of cool material in CMEs, the solar cycle dependence on CME rate, speeds and width, and the existence of flux rope within CMEs. We discuss the implications for past single-viewpoint studies and for Space Weather research. The database is publicly available on the web including all available measurements. We hope that it will become a useful resource for the community.
The Study of Spherical Cores with a Toroidal Magnetic Field Configuration
Authors: Gholipour Mahmoud 
Published: April 2017

Abstract
Observational studies of the magnetic fields in molecular clouds have significantly improved the theoretical models developed for the structure and evolution of dense clouds and for the star formation process as well. The recent observational analyses on some cores indicate that there is a power-law relationship between magnetic field and density in the molecular clouds. In this study, we consider the stability of spherical cores with a toroidal magnetic field configuration in the molecular clouds. For this purpose, we model a spherical core that is in magnetostatic equilibrium. Herein, we propose an equation of density structure, which is a modified form of the isothermal Lane–Emden equation in the presence of the toroidal magnetic field. The proposed equation describes the effect of the toroidal magnetic field on the cloud structure and the mass cloud. Furthermore, we found an upper limit for this configuration of magnetic field in the molecular clouds. Then, the virial theorem is used to consider the cloud evolution leading to an equation in order to obtain the lower limit of the field strength in the molecular cloud. However, the results show that the field strength of the toroidal configuration has an important effect on the cloud structure, whose upper limit is related to the central density and field gradient. The obtained results address some regions of clouds where the cloud decomposition or star formation can be seen.

Abstract
Recent observations have suggested that the C iii]

emission lines could be alternative diagnostic lines for galaxies in the reionization epoch. We use the F128N narrowband filter on the Hubble Space Telescope’s (HST) Wide Field Camera 3 (WFC3) to search for C iii] emission in a sample of five galaxies at z = 5.7 in the Subaru Deep Field and the Subaru/XMM-Newton Deep Field. Using the F128N narrowband imaging, together with the broadband imaging, we do not detect C iii] emission for the five galaxies with

ranging from 24.10 to 27.00 in our sample. For the brightest galaxy J132416.13+274411.6 in our sample (z = 5.70,

), which has a significantly higher signal to noise, we report a C iii] flux of

, which places a stringent 3σ upper limit of

on C iii] flux and 6.57 Å on the C iii] equivalent width. Using the stacked image, we put a 3σ upper limit on the mean C iii] flux of

and a 3σ upper limit on the mean C iii] equivalent width of 4.20 Å for this sample of galaxies at z = 5.70. Combined with strong C iii] detection reported among high-z galaxies in the literature, our observations suggest that the equivalent widths of C iii] from galaxies at z > 5.70 exhibit a wide range of distribution. Our strong limits on C iii] emission could be used as a guide for future observations in the reionization epoch.

O homem sempre necessitou conhecer o meio em que vive, por questões de sobrevivência, orientação, segurança, guerras, navegação, construção, etc. No princípio a representação do espaço baseava-se na observação e descrição do meio. Cabe salientar que alguns historiadores dizem que o homem já fazia mapas antes mesmo de desenvolver a escrita. Com o tempo surgiram técnicas e equipamentos de medição que facilitaram a obtenção de dados para posterior representação. O objetivo deste trabalho é proceder a determinação de uma área definida utilizando diferentes métodos de levantamento topográfico planimétrico e instrumentos. Para o levantamento desta poligonal foram utilizados instrumentos como: trenas de fibra de vidro, utilizando métodos geométricos para determinação da área; o levantamento por caminhamento usando teodolito digital e analógico, processando os dados de distância obtidos com estadimetria; e o levantamento por irradiação utilizando também teodolito digital e analógico, procedendo leituras estadimétricas. Os dados do levantamento foram procesados no Programa Microsoft Excel®. Verificou-se que todos os métodos de levantamento topográfico planimétrico, seja por irradiação e caminhamento, foram eficientes na determinação da área aproximada da poligonal implantada, com diferença mínima significativa entre os tipos de instrumentos no levantamento da área 2. O menor erro médio levantado se deu com o instrumento analógico na área 2 (0,6%) , enquanto que o maior erro se deu com o instrumento digital na área 2 (2,06%). O coeficiente de variação foi maior no instrumento digital na área 1 (1,41%) e menor na área 2 com o instrumento analógico (0,37%).
Les études photographiques d’après nature : un laboratoire esthétique au xixe siècle
Authors: Font-Réaulx Dominique de 
Published: April 2017

Réalisées pour les artistes et les amateurs, les études photographiques d’après nature ont fait l’objet, depuis une trentaine d’années, d’analyses renouvelées portant sur leur lien avec la peinture et le dessin de leur temps. Les nombreuses expositions et publications ont ainsi permis de renouveler, pour partie, le lien entre peinture et photographie. Cet article propose d’analyser ces études d’un point de vue de la génétique de leur propre création, offrant ainsi de retracer la conception des images elles-mêmes, en considérant la création picturale pour laquelle elles ont été utilisées non comme fin seulement, mais également comme source, comme intention première, comme ébauche. Une analyse génétique d’images, longtemps considérées comme produits mécaniques, devient alors pleinement possible ; au-delà de la représentation, c’est l’objet photographique, l’épreuve particulière utilisée spécifiquement qui pourra également faire l’objet de recherches futures.
La mise en abyme dans Le Tunnel d’Ernesto Sábato
Authors: Tuan Daniele 
Published: April 2017

Depuis l’antiquité, peinture et écriture sont considérées comme deux formes expressives antithétiques : l’une vouée à la spatialité, l’autre à la temporalité. Néanmoins, la peinture occupe une place considérable dans la littérature. Avec cet article, et dans une perspective comparatiste, nous nous proposons alors d’étudier la frontière entre écriture et peinture, à partir du rôle du détail pictural et du rôle de la mise en abyme dans le roman Le Tunnel de l’écrivain argentin Ernesto Sábato.
L’écriture poétique dans les années 1960-1970 en Espagne : le blocage de la lecture comme refuge de la voix
Authors: Lavergne Lucie 
Published: April 2017

En réponse à la crise sociale et politique qui survient dans l’Espagne des dernières années du Franquisme, une crise littéraire provoque la remise en cause du rapport du langage au réel. La poésie langagière des Novísimos et la poésie expérimentale et visuelle proposent deux réponses à cette crise, l’une langagière, l’autre anti-langagière, qui coïncident autour de la notion d’illisibilité. D’abord, les productions poétiques des Novísimos complexifient le langage au point de le rendre illisible : destruction des normes typographiques, réduction de la syntaxe à l’énumération chaotique, introduction de termes en langues étrangères, voire invention de formules ne renvoyant à aucun code linguistique. Cette difficulté langagière est le refuge du sujet qui fuit l’uniformisation de la langue. Le sens est indécidable car le discours perd sa cohérence. Sa fragmentation, ses ellipses, changements de focalisation, collages, dissolvent la cohérence de la voix-je. En retour, celle-ci s’énonce, en poésie langagière comme en poésie expérimentale, par un travail de la verticalité et de la visibilité. Celle-ci, si elle est par définition illisible, s’avère un refuge de la voix poétique face aux discours autoritaires. L’usage de la rature, qui figure la censure, reflète, en provoquant l’impossibilité de lire, l’interdiction de dire dans l’Espagne de la dictature. L’illisible constitue donc une modalité d’expression de la voix poétique.
Ecouter – voir – sentir – lire Katalin Molnár et Raymond Federman : le corps à l’épreuve
Authors: Murphy Amanda 
Published: April 2017

Le présent article examine les diverses façons dont peut être appréhendé ce qui semble a priori illisible, voire revendique sa propre illisibilité, comme il est le cas des œuvres des écrivains bilingues Raymond Federman et Katalin Molnár. Plus qu’exiger l’assiduité ou l’acquisition de connaissances qui permettraient de surmonter la « difficulté », ces œuvres nous invitent à nous arrêter et à réapprendre à lire autrement : avec le corps. Dans une relation de tension entre distance et proximité (inclusion et exclusion), les œuvres maintiennent le lecteur dans un espace intermédiaire, parfois incommode à naviguer, mais qui constitue la seule voie permettant non pas de lire, mais d’expérimenter l’oralité, et avec elle, les enjeux mémoriels des œuvres.
Surrendering to the foreignness in Alexandre Vialatte’s Battling le ténébreux
Authors: Egan  Frances 
Published: April 2017

Alexandre Vialatte’s Battling le ténébreux occupies a strange space between worlds and between languages. His background as a writer-translator imbues the text with a foreignness so that it sits between French and German traditions, and his characters, unable or not-wanting to fit in or understand their world, depict their otherness with foreign and otherworldly art. I present the rich and strange in-between space that the text and its characters inhabit as the source of its wonder, that threshold of the legible. Representative of the novel as a whole, the title “battling le ténébreux” is obscure but brilliant ; the language switch destabilises and enriches. Following this title across languages and literatures, through the intertextual trope of the beau ténébreux, through the romantic despair and the battle against melancholy, the foreign shows itself not as a veil to be lifted but as a materiality in the darkness. In this paper, I explore a foreignness of language as a means of depicting and revealing that inescapable multiplicity and uncertainty.

ABSTRACT
Background: The incidence of long-term survival in glioblastoma (GBM), i.e., >3 years, ranges from 3% to 5%. Although extensive research is performed in novel therapies for prolonging survival, there is a scarcity of research focusing on the impact of tumor and treatment on cognitive, psychological, and social status of survivors. This study is an attempt to look into this poorly addressed important issue. Materials and Methods: Nine patients (six adults and three children) with GBM who had survived >3 years were included in the study. The quality of life (QOL) functions were assessed with the World Health Organization QOL Questionnaire BREF questionnaire. The neuropsychological assessment was done using the National Institute of Mental Health and Neurosciences neuropsychology battery for adults and children. The scores were compared with normative data. Results: The physical and psychological health-related QOL of long-term GBM survivors were affected considerably due to fatigue, poor quality of sleep, inability to concentrate, presence of depression, financial burden with impaired personal and social relationships (P < 0.05). Different domains of cognitions such as motor speed (P = 0.0173), mental speed (P = 0.0022), sustained attention (P = 0.0001), long-term memory (P = 0.0431), mental flexibility (P < 0.05), and planning and executive functions (P < 0.05) were significantly impaired affecting personal, social, and professional lives. Conclusion: The health-related QOL and cognition are significantly impaired in GBM long-term survivors. As the incidence of long-term survival is very less, there is a need for larger multicenter studies to come up with definitive results, which in turn can help in formatting the rehabilitative and support programs for these patients.

Authors: Potigumjon Artit , Watcharakorn Arvemas , Dharmasaroja Pornpatr A. 
Published: April 2017

ABSTRACT
Background: With the widespread use of magnetic resonance imaging (MRI), cerebral microbleeds (CMBs) are commonly detected. Ethnicity seems to play a role in the prevalence of CMB, with higher prevalence in participants from Asian origin. The purpose of the study is to look for the prevalence of CMBs and associated factors in Thai patients with ischemic stroke. Methods: Patients with acute ischemic stroke who had MRI and magnetic resonance angiography during January–August 2014 were included in the study. T2*-weighted gradient-recalled echo was used to define CMBs. Baseline characteristics, stroke subtypes, and severity of white matter lesions were compared between patients with and without CMBs. Results: Two hundred patients were included in the study. Mean age of the patients was 61-year-old. Mean National Institutes of Health Stroke Scale was 8. The prevalence of CMBs was 20% (39/200 patients). Hypertension (odds ratio [OR] 3.05, 95% confidence interval [CI] 1.07–8.68, P = 0.037), and moderate-to-severe white matter lesions (Fazekas 2–3, OR 7.61, 95% CI 3.06–18.95, P < 0.001) were related to the presence of CMBs. Conclusions: CMBs were found in 20% of patients with ischemic stroke, which was lower than those reported from Japanese studies but comparable to a Chinese study. CMBs were associated with hypertension and severity of the white matter lesions.
Psychiatric Presentations Heralding Hashimoto’s Encephalopathy: A Systematic Review and Analysis of Cases Reported in Literature

Published: April 2017

ABSTRACTHashimoto’s encephalopathy (HE) may often present initially with psychiatric symptoms. These presentations are often variable in clinical aspects, and there has been no systematic analysis of the numerous psychiatric presentations heralding an eventual diagnosis of HE which will guide clinicians to make a correct diagnosis of HE. This systematic review was done to analyze the demographic characteristics, symptom typology, and clinical and treatment variables associated with such forerunner presentations. Electronic databases such as PubMed, ScienceDirect, and Google Scholar databases were searched to identify potential case reports that described initial psychiatric presentations of HE in English language peer-reviewed journals. The generated articles were evaluated and relevant data were extracted using a structured tool. We identified a total of forty articles that described 46 cases. More than half of the total samples (54.4%) were above the age of 50 years at presentation. The most common psychiatric diagnosis heralding HE was acute psychosis (26.1%) followed by depressive disorders (23.9%). Dementia (10.9%) and schizophrenia (2.2%) were uncommon presentations. Antithyroid peroxidase antibodies were elevated in all patients but not antithyroglobulin antibodies. Preexisting hypothyroidism was absent in majority of cases (60.9%). Steroid doses initiated were 500–1000 mg of intravenous methylprednisolone for majority (52.1%) of patients while oral steroid maintenance was required for a significant minority (39.1%). Psychiatric manifestations of HE may be heterogeneous and require a high index of clinical suspicion, especially in older adults. A range of clinical and treatment variables may assist clinicians in making a faster diagnosis and instituting prompt and effective management.
Minimally Invasive versus Open Spine Surgery: What Does the Best Evidence Tell Us?
Authors: McClelland Shearwood , Goldstein Jeffrey A. 
Published: April 2017

ABSTRACT
Background: Spine surgery has been transformed significantly by the growth of minimally invasive surgery (MIS) procedures. Easily marketable to patients as less invasive with smaller incisions, MIS is often perceived as superior to traditional open spine surgery. The highest quality evidence comparing MIS with open spine surgery was examined. Methods: A systematic review of randomized controlled trials (RCTs) involving MIS versus open spine surgery was performed using the Entrez gateway of the PubMed database for articles published in English up to December 28, 2015. RCTs and systematic reviews of RCTs of MIS versus open spine surgery were evaluated for three particular entities: Cervical disc herniation, lumbar disc herniation, and posterior lumbar fusion. Results: A total of 17 RCTs were identified, along with six systematic reviews. For cervical disc herniation, MIS provided no difference in overall function, arm pain relief, or long-term neck pain. In lumbar disc herniation, MIS was inferior in providing leg/low back pain relief, rehospitalization rates, quality of life improvement, and exposed the surgeon to >10 times more radiation in return for shorter hospital stay and less surgical site infection. In posterior lumbar fusion, MIS transforaminal lumbar interbody fusion (TLIF) had significantly reduced 2-year societal cost, fewer medical complications, reduced time to return to work, and improved short-term Oswestry Disability Index scores at the cost of higher revision rates, higher readmission rates, and more than twice the amount of intraoperative fluoroscopy. Conclusion: The highest levels of evidence do not support MIS over open surgery for cervical or lumbar disc herniation. However, MIS TLIF demonstrates advantages along with higher revision/readmission rates. Regardless of patient indication, MIS exposes the surgeon to significantly more radiation; it is unclear how this impacts patients. These results should optimize informed decision-making regarding MIS versus open spine surgery, particularly in the current advertising climate greatly favoring MIS.
