Anterior hyperlordotic cages: early experience and radiographic results
Authors: Saville Philip A. , Kadam Abhijeet B. , Smith Harvey E. , Arlet Vincent 
Published: July 2016

OBJECTIVE
The aim of this study was to evaluate the segmental correction obtained from 20° and 30° hyperlordotic cages (HLCs) used for anterior lumbar interbody fusion in staged anterior and posterior fusion in adults with degenerative spinal pathology and/or spinal deformities.

METHODS
The authors report a retrospective case series of 69 HLCs in 41 patients with adult degenerative spine disease and/or deformities who underwent staged anterior, followed by posterior, instrumentation and fusion. There were 29 females and 12 males with a mean age of 55 years (range 23–76 years). The average follow-up was 10 months (range 2–28 months). Radiographic measurements of segmental lordosis and standard sagittal parameters were obtained on pre- and postoperative radiographs. Implant subsidence was measured at the final postoperative follow-up.

RESULTS
For 30° HLCs, the mean segmental lordosis achieved was 29° (range 26°–34°), but in the presence of spondylolisthesis this was reduced to 19° (range 12°–21°) (p < 0.01). For 20° HLCs, the mean segmental lordosis achieved was 19° (range 16°–22°). The overall mean lumbar lordosis increased from 39° to 59° (p < 0.01). The mean sagittal vertical axis (SVA) reduced from 113 mm (range 38–320 mm) to 43 mm (range −13 to 112 mm). Six cages (9%) displayed a loss of segmental lordosis during follow-up. The mean loss of segmental lordosis was 4.5° (range 3°–10°). A total complication rate of 20% with a 4.1% transient neurological complication rate was observed. The mean blood loss per patient was 240 ml (range 50–900 ml).

CONCLUSIONS
HLCs provide a reliable and stable degree of segmental lordosis correction. A 30° HLC will produce correction of a similar magnitude to a pedicle subtraction osteotomy, but with a lower complication rate and less blood loss.
Implications of transitioning to a resident night float system in neurosurgery: mortality, length of stay, and resident experience
Authors: Davis Matthew C. , Kuhn Elizabeth N. , Agee Bonita S. , Oster Robert A. , Markert James M. 
Published: July 2016

OBJECTIVE
Many neurosurgical training programs have moved from a 24-hour resident call system to a night float system, but the impact on outcomes is unclear. Here, the authors compare length of stay (LOS) for neurosurgical patients admitted before and after initiation of a night float system at a tertiary care training hospital.

METHODS
The neurosurgical residency at the University of Alabama at Birmingham transitioned from 24-hour call to a night float resident coverage system in July 2013. In this cohort study, all patients admitted to the neurosurgical service for 1 year before and 1 year after this transition were compared with respect to hospital and ICU LOSs, adjusted for potential confounders.

RESULTS
A total of 4619 patients were included. In the initial bivariate analysis, night float was associated with increased ICU LOS (p = 0.032) and no change in overall LOS (p = 0.65). However, coincident with the transition to a night float system was an increased frequency of resident service transitions, which were highly associated with hospital LOS (p < 0.01) and ICU LOS (p < 0.01). After adjusting for resident service transitions, initiation of the night float system was associated with decreased hospital LOS (p = 0.047) and no change in ICU LOS (p = 0.35).

CONCLUSIONS
This study suggests that a dedicated night float resident may improve night-to-night continuity of care and decrease hospital LOS, but caution must be exercised when initiation of night float results in increased resident service transitions.
PLANETESIMAL FORMATION BY GRAVITATIONAL INSTABILITY OF A POROUS DUST DISK
Authors: Michikoshi Shugo , Kokubo Eiichiro 
Published: July 2016

ABSTRACT
It has recently been proposed that porous icy dust aggregates are formed by the pairwise accretion of dust aggregates beyond the snowline. We calculate the equilibrium random velocity of porous dust aggregates, taking into account mutual gravitational scattering, collisions, gas drag, and turbulent stirring and scattering. We find that the disk of porous dust aggregates becomes gravitationally unstable as the aggregates evolve through gravitational compression in the minimum-mass solar nebula model for a reasonable range of turbulence strength, which leads to rapid formation of planetesimals.
CAUGHT IN THE ACT: DIRECT DETECTION OF GALACTIC BARS IN THE BUCKLING PHASE
Authors: Erwin Peter , Debattista Victor P. 
Published: July 2016

ABSTRACT
The majority of massive disk galaxies, including our own, have stellar bars with vertically thick inner region, known as “boxy/peanut-shaped” (B/P) bulges. The most commonly suggested mechanism for the formation of B/P bulges is a violent vertical “buckling” instability in the bar, something that has been seen in N-body simulations for over 20 years, but never identified in real galaxies. Here, we present the first direct observational evidence for ongoing buckling in two nearby galaxies (NGC 3227 and NGC 4569), including characteristic asymmetric isophotes and (in NGC 4569) stellar kinematic asymmetries that match buckling in simulations. This confirms that the buckling instability takes place and produces B/P bulges in real galaxies. A toy model of bar evolution yields a local fraction of buckling bars consistent with observations if the buckling phase lasts ∼0.5–1 Gyr, in agreement with simulations.

Historia -chronique : Ricœur et La La Poétique
Authors: Boulay Bérenger 
Published: July 2016

Dans leur Poétique , Roselyne Dupont-Roc et Jean Lallot traduisent « historia » par « chronique », « mimèsis » par « représentation » et « muthos » par « histoire ». Ces choix de traduction auront été décisifs pour la réflexion de Paul Ricœur sur la narrativité de l’Histoire et, au-delà, pour le regain d’intérêt pour les genres factuels qu’on observe actuellement dans les études littéraires.
Si c’était à refaire…
Authors: Lallot Jean 
Published: July 2016

Jean Lallot clôt la série de témoignages sur La Poétique aux éditions du Seuil par un bilan rétrospectif sur le travail accompli avec Roselyne Dupont-Roc. Leur traduction et leurs commentaires prêtent à Aristote un propos théorique cohérent et fort : la description de la poièsis comme transfiguration ( mimèsis ) et épuration ( katharsis ) de scénarios empruntés à l’histoire ou à la tradition légendaire.
Représentation ou répétition ? À propos de la traduction du mot mimèsis dans la Poétique
Authors: Guastini Daniele 
Published: July 2016

L’article examine les raisons pour lesquelles, à la différence de la majorité des autres traducteurs, Roselyne Dupont-Roc et Jean Lallot traduisent le mot « mimèsis » par « représentation » et non par « imitation ». Indépendamment des aspects techniques qu’ils invoquent, ce choix est sous-tendu par une thèse philosophique forte, qui les incite à renvoyer la conception aristotélicienne de la mimèsis à une idée de créativité. Une telle conception semble toutefois plus redevable aux catégories de l’esthétique kantienne qu’aux catégories de la poétique aristotélicienne.
Katharsis versus mimèsis : simulation des émotions et définition aristotélicienne de la tragédie

L’article traite du fameux passage du chapitre 6 concernant la katharsis . L’article revient sur les raisons invoquées par les partisans d’une suppression ou d’une correction du terme « katharsis » et sur les débats que leurs propositions ont suscités. Il se clôt sur une suggestion nouvelle : c’est « mimèsis » qu’il faudrait lire, en lieu et place de « katharsis ».
Comment les Français perçoivent-ils l’égalité des chances ?
Authors: Forsé Michel , Parodi Maxime 
Published: July 2016

Les Français croient-ils à l’égalité des chances ? L’enquête Dynegal a posé la question en 2013 à un échantillon représentatif de 4 000 individus et leurs réponses sont très partagées. Ce sont les classes moyennes qui se montrent un peu plus convaincues que les autres par l’idée que l’école donne à chacun sa chance et que la réussite dans la vie ne dépend pas de l’origine sociale. Ce résultat va dans le sens d’une thèse de Simmel faisant de la classe moyenne le lieu de la mobilité sociale. L’enquête permet également de s’interroger sur le lien entre la croyance en l’égalité des chances et les attentes sociales en termes de reconnaissance des mérites et d’égalité des résultats. Comme on pouvait s’y attendre, moins on croit à l’égalité des chances, moins on défend la reconnaissance des mérites, et plus on demande d’égalité des résultats. En revanche, les Français parfaitement convaincus que tout le monde a les mêmes chances de réussir défendent non seulement la reconnaissance des mérites, mais aussi l’égalité des places. Ce résultat inattendu met en lumière, en fait, un risque inhérent à une société pensée comme totalement méritocratique : le risque de déconsidérer absolument les perdants et de ne pas leur trouver de places au sein de la société.
Self-Portrait of a Lady as an Absent Latinist

Published: July 2016

In The Memoirs of Colonel Hutchinson, Lucy Hutchinson not only built a vibrant vindication of her late beloved husband, but also wrote an impressive account of the English Civil War. The genre demanded that this remarkably talented and knowledgeable woman remain self-effaced behind the man she praised. Here we find her, however, as much self-enhanced as self-effaced in the guise of the great latinist she was, author of the first complete translation of Lucretius in verse.

A Switch Function-Based Gas-Kinetic Scheme for Simulation of Inviscid and Viscous Compressible Flows
Authors: Sun Yu , Shu Chang , Yang Liming , Teo C. J. 
Published: July 2016

AbstractIn this paper, a switch function-based gas-kinetic scheme (SF-GKS) is presented for the simulation of inviscid and viscous compressible flows. With the finite volume discretization, Euler and Navier-Stokes equations are solved and the SF-GKS is applied to evaluate the inviscid flux at cell interface. The viscous flux is obtained by the conventional smooth function approximation. Unlike the traditional gas-kinetic scheme in the calculation of inviscid flux such as Kinetic Flux Vector Splitting (KFVS), the numerical dissipation is controlled with a switch function in the present scheme. That is, the numerical dissipation is only introduced in the region around strong shock waves. As a consequence, the present SF-GKS can well capture strong shock waves and thin boundary layers simultaneously. The present SF-GKS is firstly validated by its application to the inviscid flow problems, including 1-D Euler shock tube, regular shock reflection and double Mach reflection. Then, SF-GKS is extended to solve viscous transonic and hypersonic flow problems. Good agreement between the present results and those in the literature verifies the accuracy and robustness of SF-GKS.
Aeroacoustic Simulations Using Compressible Lattice Boltzmann Method
Authors: Li Kai , Zhong Chengwen 
Published: July 2016

AbstractThis paper presents a lattice Boltzmann (LB) method based study aimed at numerical simulation of aeroacoustic phenomenon in flows around a symmetric obstacle. To simulate the compressible flow accurately, a potential energy double-distribution-function (DDF) lattice Boltzmann method is used over the entire computational domain from the near to far fields. The buffer zone and absorbing boundary condition is employed to eliminate the non-physical reflecting. Through the direct numerical simulation, the flow around a circular cylinder atRe=150,M=0.2 and the flow around a NACA0012 airfoil atRe=10000,M=0.8,α=0° are investigated. The generation and propagation of the sound produced by the vortex shedding are reappeared clearly. The obtained results increase our understanding of the characteristic features of the aeroacoustic sound.
Multi-Zone Ice Accretion and Roughness Models for Aircraft Icing Numerical Simulation
Authors: Zhu Chengxiang , Zhu Chunling , Guo Tao 
Published: July 2016

AbstractA mathematical multi-zone ice accretion model used in the numerical simulation of icing on airfoil surface based on three water states, namely, continuous film, rivulets and beads is studied in this paper. An improved multi-zone roughness model is proposed. According to the flow state of liquid water and film flow, rivulets flow governing equations are established to calculate film mass distribution, film velocity, rivulet wetness factor and rivulet mass distribution. Force equilibrium equations of droplet are used to establish the critical conditions of water film broken into rivulets and rivulets broken into beads. The temperature conduction inside the water layer and ice layer is considered. Using the proposed model ice accretion on a NACA0012 airfoil profile with a 4° angle of attack under different icing conditions is simulated. Different ice shapes like glaze ice, mixed ice and rime ice are obtained, and the results agree well with icing wind tunnel experiment data. It can be seen that, water films are formed on the surface, and heights of the films vary with icing time and locations. This results in spatially-temporally varying surface roughness and heat transfer process, ultimately affects the ice prediction. Model simulations indicate that the process of water film formation and evolution cannot be ignored, especially under glaze ice condition.
Evaluation of NO+ reagent ion chemistry for online measurements of
atmospheric volatile organic compounds

Published: July 2016

Abstract. NO+ chemical ionization mass spectrometry (NO+ CIMS) can achieve fast (1 Hz and faster) online measurement of trace atmospheric volatile organic compounds (VOCs) that cannot be ionized with H3O+ ions (e.g., in a PTR-MS or H3O+ CIMS instrument). Here we describe the adaptation of a high-resolution time-of-flight H3O+ CIMS instrument to use NO+ primary ion chemistry. We evaluate the NO+ technique with respect to compound specificity, sensitivity, and VOC species measured compared to H3O+. The evaluation is established by a series of experiments including laboratory investigation using a gas-chromatography (GC) interface, in situ measurement of urban air using a GC interface, and direct in situ measurement of urban air. The main findings are that (1) NO+ is useful for isomerically resolved measurements of carbonyl species; (2) NO+ can achieve sensitive detection of small (C4–C8) branched alkanes but is not unambiguous for most; and (3) compound-specific measurement of some alkanes, especially isopentane, methylpentane, and high-mass (C12–C15) n-alkanes, is possible with NO+. We also demonstrate fast in situ chemically specific measurements of C12 to C15 alkanes in ambient air.

Published: July 2016

Motivation A series of Eu2+ (0.0025≤ × ≤0.025) activated Sr2SiO4:xEu2+ (SSO:xEu2+) phosphors were synthesized via a sol-gel method. The phosphors were characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM) and photoluminescence (PL) spectroscopy. The differences between α’ and β phase of SSO in the density of states and energy band gap were investigated. Results The energy gap of α’-SSO and β-SSO are 4.489 and 4.106 eV, respectively. While, two samples showed similar total and partial densities of states. Under the excitation by the ultra violet (UV) light (365 nm), the SSO:xEu2+ phosphor exhibited a green emission band from 400 to 700 nm, which was corresponding to the transition of 5 d → 4 f of Eu2+ ions. Two emission peaks at 464 and 532 nm could be obtained through Gauss fitting curves. The ratio of the blue to green emission peak decreased with the Eu2+ concentration and the peaks shifted regularly with it. The thermal quenching property was investigated and its activation energy was calculated. The results indicated that this phosphor could be a candidate of green phosphor for UV-based light-emitting diodes (LEDs).

NORSK SAMMENDRAG128 Wistar hunrotter, 30 dager gamle, ble foret med spesialkost i fire uker pluss en forsøksperiode påmaksimalt 36 timer. Blant dyrene ble 114 forsøksdyr og 7 kontroller satt på fôr med lavt innhold avselen og jod mens 7 kontrolldyr fortsatt ble holdt på standardfôr. Etter fire uker ble seks grupperforsøksdyr gitt KI i.p. i doser fra 5 til 1000 μg I. En tredel av dyrene fra alle eksponeringsgrupper bleavlivet 18 timer etter injeksjonen, en tredel fra alle eksponeringsgrupper ble avlivet 24 timer etter injeksjonenog siste tredel ble avlivet 36 timer etter. Total T4, T3, rT3 og TSH ble bestemt i serum mensjodnivået ble bestemt som våtvektskonsentrasjonen i skjoldkjertelvevet. Ni rotter gikk tapt før forsøketkunne avsluttes. Klarest for rotter avlivet 18 timer etter jodinjeksjonen kan man se at kurven for TSH erbimodal. Man fant at jodmengder helt ned til 5-10 μg/rotte ga signifikant forhøyet TSH-nivå. Dettetilsvarer mengder som mennesker lett får i seg på daglig basis på en kost rik på sjømat. Resultatet aveksperimentet blir diskutert med bakgrunn i E.D.Williams’ 25 år gamle tese om at jod i overskudd ikosten medvirker til øket risiko for utvikling av papillært karsinom i skjoldkjertelen.
LANDSCAPE STRUCTURE IN THE LANDS OF THE UPPER COURSE OF THE BANABUIÚ RIVER, CEARÁ STATE, BRAZIL
Authors: Guimarães Clécia Cristina Barbosa , Valladares Gustavo Souza , Martins Claudia Miranda , Sayão Veridiana Maria 
Published: July 2016

The land use and the anthropic occupation of lands are activities directly related to the degradation process of the original vegetation cover because the natural vegetation must be removed so that these activities may take place, which changes the landscape as a whole. In the central hinterland of Ceará State, it is clear that the agriculture and livestock grazing practices are the main factors responsible for the vegetation fragmentation process and landscape changes. Land use and land cover mapping are widely used in the evaluation of natural landscape fragmentation, applying on them, the metrics which quantify the structure of a landscape. Thus, those metrics were used on the land use and land cover mapping of a polygon located in the central hinterland of the Ceará State in order to determine the structure of the landscape and infer how much of its natural vegetation is degraded. It should be noticed, by the land use and land cover mapping, that the landscape is divided into eight classes, namely: Urban Area, Agriculture, Water Body, Pasture, Exposed Soil, Riparian Vegetation, Open Shrub Caatinga and Dense Shrub Caatinga , and that the region has a significant percentage of natural cover (65%), but It is very fragmented in ecologically unstable patches that have small areas and large perimeters (which gives them a lot of reentrants), vulnerable to edge effects and susceptible to disappear in a very short time.
