Authors: Ru Yalu , Cheng Ruijing , Shang Jing , Zhao Yunpeng , Li Pan , Fu Chengxin 
Published: March 2017

Premise of the study:Polymorphic microsatellite markers were developed for Smilax sieboldii (Smilacaceae), a member of the S. hispida group with a biogeographic disjunction between eastern Asia and North America, to study the phylogeography and incipient speciation of this species and its close relatives.Methods and Results:Transcriptome sequencing produced 47,628 unigenes. Seventeen loci were developed from 122 randomly selected primer pairs. Polymorphism and genetic variation were evaluated for 68 accessions representing five populations of S. sieboldii. The number of alleles per locus ranged from four to 18; the expected heterozygosity ranged from 0.59 to 0.92. Twelve loci were successfully amplified in five related species: S. scobinicaulis, S. californica, S. hispida, S. moranensis, and S. jalapensis.Conclusions:These novel expressed sequence tag–derived microsatellite markers will facilitate further population genetic research of S. sieboldii and its close allies of the S. hispida group.

Abstract
We report the detection of diffuse Lyα emission, or Lyα halos (LAHs), around star-forming galaxies at z ≈ 3.78 and 2.66 in the NOAO Deep Wide-Field Survey Boötes field. Our samples consist of a total of ∼1400 galaxies, within two separate regions containing spectroscopically confirmed galaxy overdensities. They provide a unique opportunity to investigate how the LAH characteristics vary with host galaxy large-scale environment and physical properties. We stack Lyα images of different samples defined by these properties and measure their median LAH sizes by decomposing the stacked Lyα radial profile into a compact galaxy-like and an extended halo-like component. We find that the exponential scale-length of LAHs depends on UV continuum and Lyα luminosities, but not on Lyα equivalent widths or galaxy overdensity parameters. The full samples, which are dominated by low UV-continuum luminosity Lyα emitters (M
UV ≳ −21), exhibit LAH sizes of 5–6 kpc. However, the most UV- or Lyα-luminous galaxies have more extended halos with scale-lengths of 7–9 kpc. The stacked Lyα radial profiles decline more steeply than recent theoretical predictions that include the contributions from gravitational cooling of infalling gas and from low-level star formation in satellites. However, the LAH extent matches what one would expect for photons produced in the galaxy and then resonantly scattered by gas in an outflowing envelope. The observed trends of LAH sizes with host galaxy properties suggest that the physical conditions of the circumgalactic medium (covering fraction, H i column density, and outflow velocity) change with halo mass and/or star formation rates.

Abstract
We analyze new far-ultraviolet spectra of 13 quasars from the

COS-Halos survey that cover the H i Lyman limit of 14 circumgalactic medium (CGM) systems. These data yield precise estimates or more constraining limits than previous COS-Halos measurements on the H i column densities

. We then apply a Monte-Carlo Markov chain approach on 32 systems from COS-Halos to estimate the metallicity of the cool (

K) CGM gas that gives rise to low-ionization state metal lines, under the assumption of photoionization equilibrium with the extragalactic UV background. The principle results are: (1) the CGM of field L* galaxies exhibits a declining H i surface density with impact parameter

(at

confidence), (2) the transmission of ionizing radiation through CGM gas alone is 70 ± 7%; (3) the metallicity distribution function of the cool CGM is unimodal with a median of

and a 95% interval

to

; the incidence of metal-poor (

) gas is low, implying any such gas discovered along quasar sightlines is typically unrelated to L* galaxies; (4) we find an unexpected increase in gas metallicity with declining

(at

confidence) and, therefore, also with increasing

; the high metallicity at large radii implies early enrichment; and (5) a non-parametric estimate of the cool CGM gas mass is

, which together with new mass estimates for the hot CGM may resolve the galactic missing baryons problem. Future analyses of halo gas should focus on the underlying astrophysics governing the CGM, rather than processes that simply expel the medium from the halo.
Inferring the Heliospheric Magnetic Field Back through Maunder Minimum

Published: March 2017

Abstract
Recent solar conditions include a prolonged solar minimum (2005–2009) and a solar maximum that has not fully recovered in terms of the Heliospheric Magnetic Field (HMF) strength when compared to the previous maximum values. These anomalies may indicate that we are entering an era of lower solar activity than observed at other times during the space age. We study past solar grand minima, especially the Maunder period (1645–1715) to gain further insight into grand minima. We find the timescale parameters associated with three processes attributed to the magnetic flux balance in the heliosphere using chi-square analysis. We use HMF time series reconstructed based on geomagnetic data and near-Earth spacecraft measurements (OMNI) data to find the fundamental timescales that influence heliospheric field evolution through conversion or opening of magnetic flux from coronal mass ejections (CMEs) into the ambient heliospheric field, removal or loss of the ambient heliospheric field through magnetic reconnection, and interchange reconnection between CME magnetic flux and ambient heliospheric magnetic flux. We also investigate the existence of a floor in the heliospheric magnetic flux, in the absence of CMEs, and show that a floor

nT is sufficient to successfully describe the HMF evolution. The minimum value for the HMF at 1 au in the model-predicted historic record is 3.13 ± 0.35 nT. Our model results favorably reproduce paleocosmic data and near-Earth spacecraft measurements data and show how the HMF may evolve through periods of extremely low activity.
Théodose II, Constantinople et l’Empire : une nouvelle lecture de la Notitia urbis Constantinopolitanae
Authors: Havaux Marie 
Published: March 2017

Jusqu’à présent, la Notitia urbis Constantinopolitanae (désormais NuC ) a été étudiée principalement pour ses apports sur la topographie et l’administration de Constantinople dans la première moitié du v	e siècle. Sa rédaction – entre 424 et 427 – se situe pourtant à un moment charnière du règne de Théodose II (408-450). En effet, quelques mois après la mort d’Honorius (423), le primicerius notariorum Jean se proclame Auguste à Rome. Théodose II réagit en lui déclarant la guerre et, après l’avoir élimé, élève son cousin Valentinien au rang d’Auguste pour la partie occidentale de l’Empire. Considérée dans ce contexte, la Notitia apparaît bien plus qu’un document destiné à l’usage de la préfecture urbaine. En effet, le texte comporte un contenu idéologique notable axé sur le statut de Constantinople en tant que capitale de l’Empire romain d’Orient, et sur la glorification de la dynastie théodosienne, et ce, notamment par l’utilisation des topoi du panégyrique de cité. Ainsi, la NuC affirme le rôle central – et désormais prépondérant par rapport à Rome – de Constantinople au sein de l’Empire.
Subfoveal Choroidal Vascularity in Myopia: Evidence From Spectral-Domain Optical Coherence Tomography
Authors: Alshareef Rayan A. , Khuthaila Mohammed K. , Goud Abhilash , Vupparaboina Kiran Kumar , Jana Soumya , Chhablani Jay 
Published: March 2017

BACKGROUND AND OBJECTIVE:
To evaluate subfoveal choroidal vascularity in eyes with myopia in comparison to age-matched healthy subjects.

PATIENTS AND METHODS:
Retrospective analysis of single foveal enhanced depth imaging optical coherence tomography (EDI-OCT) scans of 30 eyes with myopia (axial length greater than 25 mm). Subfoveal choroidal vascularity was evaluated by calculating vessel-area-to-stromal-area ratio using a previously validated automated algorithm.

RESULTS:

The subfoveal stromal area was significantly smaller in myopes (0.95 mm
3
± 0.22 mm
3
) compared to controls (1.33 mm
3
± 0.23 mm
3
;
P
< .0001). However, there was no significant difference in vascular area or in vessel-area-to-stroma-area ratio between the groups (
P
= .15 and
P
= .16, respectively). Subfoveal choroidal vascularity percentage was also not significantly different between the two groups (
P
= .07).

CONCLUSION:
Subfoveal choroidal thinning in myopia is primarily associated with a reduction in choroidal stroma, not vascular components. This needs further exploration and has potential clinical applications.

Published: March 2017

BACKGROUND AND OBJECTIVE:
To investigate the outcomes of combined pars plana vitrectomy (PPV), transient keratoprosthesis (TKP), and penetrating keratoplasty (PKP) in patients with coexisting corneal and vitreoretinal diseases.

PATIENTS AND METHODS:
Patients who underwent PPV, TKP, and PKP were included. The main outcome measures were change in visual acuity (VA), clarity of the graft, and retinal attachment.

RESULTS:
Twenty eyes were included. The mean follow-up time was 18 months ± 9.5 months. The baseline VA was light perception in 15 eyes and hand motions in five eyes and was found to be increased in 15 eyes (75%), decreased in one eye (5%), and stable in four eyes (20%). The mean corneal graft survival time was 11.1 months ± 8.5 months. Three eyes (15%) showed phthisis bulbi at the last visit.

CONCLUSION:
The triple procedure seems to be an effective treatment option in patients who suffer from coexisting corneal and vitreoretinal diseases.

Published: March 2017

Jenny Zobel, fille de l’écrivain martiniquais Joseph Zobel, et Emily Zobel Marshall, petite-fille de Joseph Zobel, ont découvert récemment des manuscrits inédits de leur père et grand-père. Il s’agit, d’une part, d’une collection de lettres envoyées par Joseph en 1946-1947 depuis Paris à sa femme et à son ami martiniquais Valbrun Apat, et, d’autre part, d’extraits de son journal intime des années 1940. Elles nous proposent une analyse qui répondrait à la question « Qu’apporte la lecture de ces manuscrits à l’étude des œuvres de Joseph Zobel ? »1
Les archives d’Aimé Césaire sur le site André Breton
Authors: Véron Kora 
Published: March 2017

Le Site André Breton offre aux chercheurs des ressources exceptionnelles sur la constellation surréaliste : par leur nombre, leur variété, leur intérêt. Les documents concernant Aimé Césaire, relatifs à une période allant surtout de 1942 à 1948, sont d’autant plus précieux que le poète martiniquais n’a conservé lui-même que très peu d’archives. Ils révèlent l’art poétique combinatoire de Césaire, à travers la genèse tourmentée du recueil Les Armes miraculeuses, et permettent d’apprécier le lien entre le jeune poète et son aîné, en exil dans le Nouveau Monde.
Healthcare Team Perceptions of a Portal for Parents of Hospitalized Children Before and After Implementation
Authors: Kelly Michelle M. , Dean Shannon M. , Carayon Pascale , Wetterneck Tosha B. , Hoonakker Peter L.T. 
Published: March 2017

Summary
Background. Patient electronic health record (EHR) portals can enhance patient and family engagement by providing information and a way to communicate with their healthcare team (HCT). However, portal implementation has been limited to ambulatory settings and met with resistance from HCTs.
Objective. We evaluated HCT perceptions before and 6-months after implementation of an inpatient EHR portal application on a tablet computer given to parents of hospitalized children. Methods. This repeated cross-sectional study was conducted with HCT members (nurses, physicians, ancillary staff) on a medical/surgical unit at a quaternary children’s hospital. From December 2014-June 2015, parents of children <12 years old were given a portal application on a tablet computer. It provided real-time vitals, medications, lab results, schedules, education, HCT information and a way to send the HCT messages/requests. HCT members completed surveys pre- and post-implementation regarding their portal perceptions. Pre-post differences in HCT perceptions were compared using chi-squared, Mann-Whitney and Kruskall Wallis tests.
Results. Pre-implementation, HCT respondents (N=94) were generally optimistic about the benefits of a portal for parents; however, all anticipated challenges to portal use. Over the next 6-months, 296 parents used the portal, sending 176 requests and 36 messages. Post-implementation, HCT respondent (N=70) perceptions of these challenges were significantly reduced (all p<0.001), including: parents (will) have too many questions (69 vs. 3%, pre-post), parents (will) know results before the HCT (65 vs. 1%), staff (would be/are) skeptical (43 vs. 21%) and there (will be/is) not enough technical support (28 vs. 1%).
Conclusions. All HCT respondents anticipated challenges in providing a portal to parents of hospitalized children; however, these concerns were minimized after implementation.
Iterative feedback tuning of wind turbine controllers
Authors: van Solingen Edwin , Mulders Sebastiaan Paul , van Wingerden Jan-Willem 
Published: March 2017

Abstract. Traditionally, wind turbine controllers are designed using first principles or linearized or identified models. The aim of this paper is to show that with an automated, online, and model-free tuning strategy, wind turbine control performance can be significantly increased. For this purpose, iterative feedback tuning (IFT) is applied to two different turbine controllers: drivetrain damping and collective pitch control. The results, obtained by high-fidelity simulations using the NREL 5MW wind turbine, indicate significant performance improvements over baseline controllers, which were designed using classical loop-shaping techniques. It is concluded that iterative feedback tuning of turbine controllers has the potential to become a valuable tool to improve wind turbine performance.
Is early cannulation of an arteriovenous fistula associated with early failure of the fistula?
Authors: Wilmink Teun , Hollingworth Lee , Stevenson Tamasin , Powers Sarah 
Published: March 2017

Objective To study the effect of early cannulation of arteriovenous fistulas (AVF) on early AVF failure. Methods Analysis of two databases of access operations and dialysis sessions from 1/12/2002 till 1/4/2015. Follow-up until 1/4/2016. Functional dialysis use defined as six consecutive cannulations of the AVF with two needles. Early cannulation defined as needling of the AVF within 30 days of creation. Early failure was defined as abandonment for new form of access within 90 days of first cannulation. Machine blood-flow rates (BFR) of each dialysis session for the first 2 months collected from the dialysis database. Results We analysed 1167 AVFs with functional dialysis use. Some 148 AVFs (11%) were needled within 30 days. Early needling was not associated with increased early failure rates (p = 0.43). Early failure rates were lower in AVFs with six consecutive successful cannulations from the start (p = 0.002). There was a trend of reduced early failure rates (test for trend: p = 0.018) in the latter years of the study period, but no trend in early cannulation rates (p = 0.19). Failure to achieve six successful cannulations from the start was an independent predictor of early AVF failure but early needling was not an independent predictor in multivariate analysis. Average starting BFRs were higher in AVF that were needled early. Conclusions Early cannulation was not associated with early failure. Failure to achieve six successful cannulations from the start was an independent predictor of early failure. The trend in yearly variation of early failure rates suggests that evolving practices influenced early failure rates.

Disaster recovery preparedness in safety regions in the Netherlands: An exploratory study
This article addresses disaster recovery preparedness characteristics prescribed by literature and guidelines. An exploratory study was conducted in 25 Dutch safety regions to describe the status of disaster recovery preparedness with an emphasis on psychosocial support aspects. The study pointed at substantial cross-regional variation. Particular areas of improvement were identified in relation to involving citizens and partner organizations in safety regions’ recovery planning efforts, and the extent to which preparedness activities are guided by regional risk profiles. Optimization of preparedness takes place in an everyday context where relatively little priority is assigned to disaster recovery. Also, as major crises are fairly scarce there is little room for learning or routinization. Deliberate investments to enhance disaster recovery preparedness are needed, they would however benefit from more research into the association between relevant conditions, the disaster recovery preparedness level and the quality of service delivery when an event actually takes place.
Fertility care interventions should be provided as the first line options for HIV+ serodiscordant couples who desire children in settings with affordable access to care, regardless of their fertility status
Authors: Safier Lauren Zakarin , Sauer Mark V 
Published: March 2017

AbstractIntroduction: With increasing life expectancy, couples with at least one partner afflicted with HIV are more commonly pursuing the opportunity to have biologic offspring. Currently, there are no universally accepted recommendations regarding first line reproductive treatments for HIV serodiscordant couples lacking a history of infertility. We strongly believe that fertility care intervention should be the first line treatment, when affordably accessible, over natural conception for HIV serodiscordant couples to achieve pregnancy in a safe and efficacious manner.Discussion: In the era of highly active anti‐retroviral therapy, in combination with timed intercourse and pre‐exposure prophylaxis for the HIV negative partner, some members of the medical community are arguing in favour of natural conception as a means of achieving pregnancy in this patient population. In our opinion, laboratory assisted fertility methods, including intrauterine insemination, in vitro fertilization, and intracytoplasmic sperm injection with semen washing should be the first line treatment recommendation for HIV serodiscordant couples desiring pregnancy for the following reasons: (1) abundance of evidence in the medical literature supporting the safety profile and efficacy of fertility care intervention in couples with HIV; paucity of data addressing safety of natural conception in comparison to fertility intervention techniques (2) unknown public health impact of promoting natural conception as a safe means of achieving pregnancy (3) ethical implications: patients should be offered the available and accessible treatment option posing the lowest possible known risk to the uninfected partner.Conclusions: We believe that physician assisted fertility care, when affordably accessible, should be the treatment of choice over natural conception. While the preliminary data on natural conception in couples using highly active anti‐retroviral therapy/pre‐exposure prophylaxis/timed intercourse appears promising, we believe that this approach should be limited to patients in resource poor settings where more sophisticated measures do not exist or for patients that simply cannot afford subspecialty care. There are likely to be unknown psychological and behavioural factors impacted by promoting natural conception and diminishing the importance of safe sex practices. Additionally, it is our moral obligation to patients to offer the affordably accessible treatment interventions that pose the least known risk when considering reproductive options.
