Abstract
The census of Taurus–Auriga has been assembled over seven decades and inherited the biases and incompleteness of the input studies. The unusual shape of its inferred initial mass function (IMF) and the existence of isolated disk-bearing stars suggest that additional (likely disk-free) members remain to be discovered. We therefore have begun a global reassessment of the census of Taurus–Auriga that exploits new data and better definitions of youth and kinematic membership. As a first step, we reconsider the membership of all disk-free candidate members from the literature with spectral type ≥F0,

, and

. We combine data from the literature with Keck/HIRES and UH88/SNIFS spectra to test the membership of these candidates using the positions in the Hertzsprung-Russel diagram, proper motions, radial velocities, Hα, lithium, and surface gravity. We find 218 confirmed or likely Taurus members, 160 confirmed or likely interlopers, and only 18 that lack sufficient evidence to draw firm conclusions. A significant fraction of these stars (81/218 = 37%) are not included in the most recent canonical member lists. There are few additional members to the immediate vicinity of the molecular clouds, preserving the IMFs that have been deemed anomalous in past work. Many of the likely Taurus members are instead distributed broadly across the search area. When combined with the known disk hosts, our updated census reveals two regimes: a high-density population with a high disk fraction (indicative of youth) that broadly traces the molecular clouds, and a low-density population with low disk fraction (hence likely older) that most likely represents previous generations of star formation.
New Physical Insights about Tidal Disruption Events from a Comprehensive Observational Inventory at X-Ray Wavelengths
Authors: Auchettl Katie , Guillochon James , Ramirez-Ruiz Enrico 
Published: April 2017

Abstract
We perform a comprehensive study of the X-ray emission from 70 transient sources that have been classified as tidal disruption events (TDEs) in the literature. We explore the properties of these candidates, using nearly three decades of X-ray observations to quantify their properties and characteristics. We find that the emission from X-ray TDEs increase by two to three orders of magnitude, compared to pre-flare constraints. These emissions evolve significantly with time, and decay with power-law indices that are typically shallower than the canonical t
−5/3 decay law, implying that X-ray TDEs are viscously delayed. These events exhibit enhanced (relative to galactic) column densities and are quite soft in nature, with no strong correlation between the amount of detected soft and hard emission. At their peak, jetted events have an X-ray to optical ratio ≫1, whereas non-jetted events have a ratio ∼1, which suggests that these events undergo reprocessing at different rates. X-ray TDEs have long T
90 values, consistent with what would be expected from a viscously driven accretion disk formed by the disruption of a main-sequence star by a black hole with a mass <107
M
⊙. The isotropic luminosities of X-ray TDEs are bimodal, such that jetted and non-jetted events are separated by a “reprocessing valley” that we suggest is naturally populated by optical/UV TDEs that most likely produce X-rays, but this emission is “veiled” from observations due to reprocessing. Our results suggest that non-jetted X-ray TDEs likely originate from partial disruptions and/or disruptions of low-mass stars.
Spatially Offset Active Galactic Nuclei. II. Triggering in Galaxy Mergers
Authors: Barrows R. Scott , Comerford Julia M. , Greene Jenny E. , Pooley David 
Published: April 2017

Abstract
Galaxy mergers are likely to play a role in triggering active galactic nuclei (AGNs), but the conditions under which this process occurs are poorly understood. In Paper I, we constructed a sample of spatially offset X-ray AGNs that represent galaxy mergers hosting a single AGN. In this paper, we use our offset AGN sample to constrain the parameters that affect AGN observability in galaxy mergers. We also construct dual-AGN samples with similar selection properties for comparison. We find that the offset AGN fraction shows no evidence for a dependence on AGN luminosity, while the dual-AGN fractions show stronger evidence for a positive dependence, suggesting that the merger events forming dual AGNs are more efficient at instigating accretion onto supermassive black holes than those forming offset AGNs. We also find that the offset and dual-AGN fractions both have a negative dependence on nuclear separation and are similar in value at small physical scales. This dependence may become stronger when restricted to high AGN luminosities, although a larger sample is needed for confirmation. These results indicate that the probability of AGN triggering increases at later merger stages. This study is the first to systematically probe down to nuclear separations of <1 kpc (∼0.8 kpc) and is consistent with predictions from simulations that AGN observability peaks in this regime. We also find that the offset AGNs are not preferentially obscured compared to the parent AGN sample, suggesting that our selection may be targeting galaxy mergers with relatively dust-free nuclear regions.

Abstract
We use the Atacama Large Millimeter Array (ALMA) to detect and image CO (1-0) emission from Minkowski’s Object, a dwarf galaxy in the cluster Abell 194 that is interacting with a radio jet from a nearby elliptical galaxy. The ALMA observations, which are the first to detect molecular gas in Minkowski’s Object, also image the high-frequency continuum emission from the radio jet, allowing us to study the interaction in detail. We estimate the range in the mass of molecular gas in Minkowski’s Object assuming two different values of the ratio of the molecular gas mass to the CO luminosity,

. For the Milky Way value of

we obtain a molecular gas mass of

, 6% of the H I gas mass. We also use the prescription of Narayanan et al. (2012) to estimate an

, in which case we obtain

, 36% of the H I mass. The observations are consistent with previous claims of star formation being induced in Minkowski’s Object via the passage of the radio jet, and it therefore being a rare local example of positive feedback from an active galactic nucleus. In particular, we find highly efficient star formation, with gas depletion timescales

year (for assumed values of

and

, respectively) in the upstream regions of Minkowski’s Object that were struck first by the jet, and less efficient star formation downstream. We discuss the implications of this observation for models of jet-induced star formation and radio-mode feedback in massive galaxies.
Differences in Breeding Bird Assemblages Related to Reed Canary Grass Cover and Forest Structure on the Upper Mississippi River
Authors: Kirsch Eileen M. , Gray Brian R. 
Published: April 2017

Abstract
Floodplain forest of the Upper Mississippi River provides habitat for an abundant and diverse breeding bird community. However, reed canary grass Phalaris arundinacea invasion is a serious threat to the future condition of this forest. Reed canary grass is a well-known aggressive invader of wetland systems in the northern tier states of the conterminous United States. Aided by altered flow regimes and nutrient inputs from agriculture, reed canary grass has formed dense stands in canopy gaps and forest edges, retarding tree regeneration. We sampled vegetation and breeding birds in Upper Mississippi River floodplain forest edge and interior areas to 1) measure reed canary grass cover and 2) evaluate whether the breeding bird assemblage responded to differences in reed canary grass cover. Reed canary grass was found far into forest interiors, and its cover was similar between interior and edge sites. Bird assemblages differed between areas with more or less reed canary grass cover (&gt;53% cover breakpoint). Common yellowthroat Geothlypis trichas, black-capped chickadee Parus atricapillus, and rose-breasted grosbeak Pheucticus ludovicianus were more common and American redstart Setophaga ruticilla, great crested flycatcher Myiarchus crinitus, and Baltimore oriole Icterus galbula were less common in sites with more reed canary grass cover. Bird diversity and abundance were similar between sites with different reed canary grass cover. A stronger divergence in bird assemblages was associated with ground cover &lt;15%, resulting from prolonged spring flooding. These sites hosted more prothonotary warbler Protonotaria citrea, but they had reduced bird abundance and diversity compared to other sites. Our results indicate that frequently flooded sites may be important for prothonotary warblers and that bird assemblages shift in response to reed canary grass invasion.
De l’exposition au livre d’art
Authors: Lin Chi-Ming 
Published: April 2017

The History of Photography par Beaumont Newhall, conservateur fondateur du département de la Photographie du MoMA de New York, est l’ouvrage représentatif du paradigme moderniste de l’écriture de l’histoire de la photographie. L’article retrace d’abord comment cet important ouvrage, né d’un catalogue d’exposition, a évolué au fil des cinq éditions successives. La sélection et l’emplacement des images constituent un autre volet du travail de Newhall ; la place emblématique des œuvres d’Alfred Stieglitz dans les différentes éditions du livre dévoile des stratégies et des pensées qui posent l’auteur de cette Histoire en figure de « curator » (commissaire d’exposition). La fin de l’article propose de remplacer le modèle de génétique textuelle par un « modèle exposition », afin de mieux tenir compte du rôle de l’iconographie et du travail déterminant du commissaire-historien dans la genèse de ce type d’ouvrage.
Recyclages photographiques
Authors: Crestey Muriel Berthou 
Published: April 2017

En quoi les processus de reprises d’images peuvent-ils générer des formes d’invention en photographie ? L’étude du phénomène de « recyclage photographique » suppose de réaliser un dossier de genèse en repérant les phases de création qui répondent à des protocoles variés : recadrages, photomontages, recollages, reprises ou accumulation d’images et manipulations dont il s’agit de retracer la chronologie. Les raisons de ces réinvestissements sont multiples (hommage, critique, mode d’expérimentation plastique…). La nature des images reprises est variable (carte postale, image vernaculaire ou chef-d’œuvre). Les moyens utilisés permettent d’aborder différentes procédures, allant du « copier-coller » à l’« autoplagiat », en passant par la juxtaposition d’images, le recyclage technique, technologique, matériel et littéral, voire théorique. Les archives deviennent un vivier créatif. Ces stratagèmes ouvrent la voie à des modes opératoires de déplacement, de citation, de transposition et de passages successifs d’un référent à l’autre.

ABSTRACT
Objective: The objective of this study is to assess the prevalence of sleep disorders among children aging between 4 and 9 years using Hindi version of Pediatric Sleep Questionnaire (PSQ). Methods: This study had two parts first, translation and validation of PSQ into Hindi language, and second, assessment of the prevalence of sleep disorders using PSQ Hindi version. Hindi PSQ was distributed in randomly chosen primary schools in a semi-urban area. The children were requested to get them filled by their parents. When the questionnaires were returned, responses were analyzed. Results: Most of the items of the Hindi version had perfect agreement with original questionnaire in a bilingual population (κ =1). Totally, 435 children were included in the field study having average age of 6.3 years. Obstructive sleep apnea was reported in 7.5% children; symptoms suggestive of restless legs syndrome were reported by 2%–3%; teeth grinding by 13.9% and sleep talking by 22.6% children. Conclusion: PSQ Hindi version is a validated tool to screen for sleep disorders among children. Sleep disorders are fairly prevalent among young children in India.

Published: April 2017

ABSTRACT
Background: Changes in platelet indices have been reported in patients with panic disorder (PD). However, previous study findings are contradictory and inconclusive. The aim of this study was to evaluate and compare the platelet indices in patients with PD. Materials and Methods: Patients with PD (n = 123) and healthy controls (n = 133) were enrolled in this case control study. The platelet indices (mean platelet volume [MPV] and platelet distribution width [PDW]) along with red blood cell (RBC) indices (RBC count and red cell distribution width [RDW]) were compared between the two groups using the unpaired t-test. Results: Patients with PD had lower MPV (7.53 ± 0.93 fL vs. 8.91 ± 1.24 fL, P < 0.0001), higher PDW (16.96 ± 0.85 fL vs. 14.71 ± 2.07 fL, P < 0.0001), and higher platelet count (274.2 ± 80.66 × 109 L−1 vs. 243.1 ± 93.89 × 109 L−1, P < 0.005) than the healthy controls. Furthermore, there were significant differences between patients with PD and healthy controls in terms of their RBC count (4.32 ± 0.56 × 1012 L−1 vs. 4.08 ± 0.80 × 1012 L−1, P = 0.007) and RDW (16.48 ± 2.26 fL vs. 15.01 ± 2.25 fL, P < 0.0001). Conclusion: Patients with PD have increased PDW and RDW. The platelet and RBC indices may prove to be useful etiological and prognostic markers in patients with PD.
Psychiatric Comorbidity in Children with Epilepsy: A Cross-sectional 5 Years Rural Prevalence Study
Authors: Dharmadhikari Ambrish Sanjay , Sinha Vinod Kumar 
Published: April 2017

ABSTRACT
Background: Epilepsy is one of the most common chronic neurological disorders. In children, it has long debilitating course and is associated with comorbidities including psychiatric comorbidity. To tackle this burden of comorbidities, we must know the extent of problem. Hence, there is a need for estimation of prevalence of psychiatry disorder in children with epilepsy. Aim: The present study was aimed at measuring the prevalence of various psychiatry disorders among children suffering from epilepsy. Settings and Design: Cross-sectional chart review. Methodology: We reviewed case record files of all patients with a diagnosis of epilepsy in the age group of 9–17 years. Chart review was done for 5 years, May 1, 2007, to April 30, 2012. A total of 718 patients record were included in the study after satisfying inclusion criteria and excluding nonepilepsy diagnosis. Statistical Analysis: Statistics was done using Statistical Package for Social Sciences (SPSS 18.0). Descriptive statistics were used to calculate the result, Chi-square and Mann–Whitney U-test used wherever applicable. Results: The prevalence of childhood psychiatric disorder among children with epilepsy found to be 31.2%. We also found that having a partial component (73.21%, n = 164) in seizure has more chances of psychopathology in comparison to generalized seizure (8.1%, n = 18). Among them, those having a partial component with generalization (66.96%, n = 150) had a greater prevalence of psychopathology. Mental retardation was most common psychiatric disorder among psychopathology followed by manic/depressive illness (unipolar) followed by unspecified nonorganic psychosis. Conclusion: From our study, we demonstrate the significant mental health needs of children with epilepsy. The evident high prevalence of psychiatry disorder emphasizes the need for psychopathology assessment and treatment as a part of any comprehensive epilepsy clinic.
Examining Perceptions of Computerized Physician Order Entry in a Neonatal Intensive Care Unit

Published: April 2017

SummaryBackground: Computerized provider order entry (CPOE) is a technology with potential to transform care delivery. While CPOE systems have been studied in adult populations, less is known about the implementation of CPOE in the neonatal intensive care unit (NICU) and perceptions of nurses and physicians using the system.Objective: To examine perceptions of clinicians before and after CPOE implementation in the NICU of a pediatric hospital.Methods: A cross-sectional survey of clinicians working in a Level III NICU was conducted. The survey was distributed before and after CPOE implementation. Participants were asked about their perception of CPOE on patient care delivery, implementation of the system, and effect on job satisfaction. A qualitative section inquired about additional concerns surrounding implementation. Responses were tabulated and analyzed using the Chi-square test.Results: The survey was distributed to 158 clinicians with a 47% response rate for pre-implementation and 45% for post-implementation. Clinicians understood why CPOE was implemented, but felt there was incomplete technical training. The expectation for increased job satisfaction and ability to recruit high-quality staff was high. However, there was concern about the ability to deliver appropriate treatments before and after implementation. Physicians were more optimistic about CPOE implementation than nurses who remained concerned that workflow may be altered.Conclusions: Introducing CPOE is a potentially risky endeavor and must be done carefully to mitigate harm. Although high expectations of the system can be met, it is important to attend to differing expectations among clinicians with varied levels of comfort with technology. Interdisciplinary collaboration is critical in planning a functioning CPOE to ensure that efficient workflow is maintained and appropriate supports for individuals with a lower degree of technical literacy is available.Citation: Beam KS, Cardoso M, Sweeney M, Binney G, Weingart SN.

SummaryBackground: Patient matching is a key barrier to achieving interoperability. Patient demographic elements must be consistently collected over time and region to be valuable elements for patient matching.Objectives: We sought to determine what patient demographic attributes are collected at multiple institutions in the United States and see how their availability changes over time and across clinical sites.Methods: We compiled a list of 36 demographic elements that stakeholders previously identified as essential patient demographic attributes that should be collected for the purpose of linking patient records. We studied a convenience sample of 9 health care systems from geographically distinct sites around the country. We identified changes in the availability of individual patient demographic attributes over time and across clinical sites.Results: Several attributes were consistently available over the study period (2005–2014) including last name (99.96%), first name (99.95%), date of birth (98.82%), gender/sex (99.73%), postal code (94.71%), and full street address (94.65%). Other attributes changed significantly from 2005–2014: Social security number (SSN) availability declined from 83.3% to 50.44% (p<0.0001). Email address availability increased from 8.94% up to 54% availability (p<0.0001). Work phone number increased from 20.61% to 52.33% (p<0.0001).Conclusions: Overall, first name, last name, date of birth, gender/sex and address were widely collected across institutional sites and over time. Availability of emerging attributes such as email and phone numbers are increasing while SSN use is declining. Understanding the relative availability of patient attributes can inform strategies for optimal matching in healthcare.Citation: Culbertson A, Goel S, Madden MB, Jackson KL, Carton T, Waitman R, Liu M, Krishnamurthy A, Hall L, Cappella N, Visweswaran S, Safaeinili N, Becich MJ, Applegate R, Bernstam E, Rothman R, Matheny M, Lipori G, Bian J, Hogan W, Bell D, Martin A, Grannis S, Klann J, Sutphen R, O’Hara AB, Kho A.

Atmospheric circulation types and extreme areal precipitation in southern central Europe

Published: April 2017

Abstract. Gridded daily rainfall data for southern central Europe are aggregated to regions of similar precipitation variability by means of S-mode principal component analyses separately for the meteorological seasons. Atmospheric circulation types (CTs) are derived by a particular clustering technique including large-scale fields of SLP, vertical wind and relative humidity at the 700 hPa level as well as the regional rainfall time series. Multiple regression models with monthly CT frequencies as predictors are derived for monthly frequencies and amounts of regional precipitation extremes (beyond the 95 % percentile). Using predictor output from different global climate models (ECHAM6, ECHAM5, EC-EARTH) for different scenarios (RCP4.5, RCP8.5, A1B) and two projection periods (2021–2050, 2071–2100) leads to assessments of future changes in regional precipitation extremes. Most distinctive changes are indicated for the summer season with mainly increasing extremes for the earlier period and widespread decreasing extremes towards the end of the 21st century, mostly for the strong scenario. Considerable uncertainties arise from the predictor use of different global climate models, especially during the winter and spring seasons.
