FUV Photoionization of Titan Atmospheric Aerosols
Authors: Tigrine Sarah , Carrasco Nathalie , Bozanic Dusan K. , Garcia Gustavo A. , Nahon Laurent
Published: November 2018

Thanks to the Cassini–Huygens mission, it is now established that the first aerosols in Titan’s upper atmosphere are found from an altitude of ∼1200 km. Once they are formed and through their descent toward the surface, these nanoparticles are submitted to persistent far-ultraviolet (FUV) radiation that can reach lower atmospheric layers. Such an interaction has an impact, especially on the chemistry and charge budget of the atmospheric compounds. Models are useful to understand this photoprocessing, but they lack important input data such as the photoemission threshold or the absolute photoabsorption/emission cross sections of the aerosols. In order to quantify the photoemission processes, analogs of Titan’s aerosols have been studied with the DESIRS FUV beamline at the synchrotron SOLEIL as isolated substrate-free nanoparticles. We present here the corresponding angle-resolved photoelectron spectroscopy data recorded at different FUV photon energies. The results show a very low photoionization threshold (6.0 ± 0.1 eV ∼ 207 nm) and very high absolute ionization cross sections (∼106 Mb), indicating that FUV photoemission from aerosols is an intense source of slow electrons that has to be taken into account in photochemical models of Titan’s atmosphere.
A New Generation of Cool White Dwarf Atmosphere Models. II. A DZ Star with Collision-induced Absorption
Authors: Blouin S. , Dufour P. , Allard N. F. , Kilic M.
Published: November 2018

In the first paper of this series, we presented our upgraded cool white dwarf atmosphere code. In this second paper, we use our new models to analyze SDSS J080440.63+223948.6 (J0804+2239), the first DZ star to show collision-induced absorption (CIA). This object provides a crucial test for our models, since previous versions of our code were unable to simultaneously fit the metal absorption lines and the CIA. We find an excellent fit to both the spectroscopic and photometric data, which further validates the improved constitutive physics of our models. We also show that the presence of metal lines allows lift of the degeneracy between high and low hydrogen abundances that usually affects the fits of white dwarfs with CIA. Finally, we investigate the potential impact of spectroscopically undetected metals on the photometric solutions of DC stars.
The AGN Ionization Cones of NGC 5728. I. Excitation and Nuclear Structure
Authors: Durré Mark , Mould Jeremy
Published: November 2018

We explore the gas morphology and excitation mechanisms of the ionization cones of the Type II Seyfert galaxy NGC 5728. Near-IR and optical data from the SINFONI and MUSE integral field units on the Very Large Telescope are combined with Hubble Space Telescope optical images, Chandra X-ray data, and Very Large Array radio observations. The complex nuclear structure has a star-forming (SF) ring with a diameter of 2 kpc. A radio jet impacts on the interstellar medium at about 200 pc from the nucleus, with the supernova remnants in the SF ring also present. Emission-line ratios of [Fe ii] and H ii show heavy extinction toward the nucleus, moderate extinction in the SF ring, and reduced extinction in the ionization cones. The active galactic nucleus (AGN) is hidden by a dust bar with up to 19 mag of visual extinction; the dust temperature at the nuclear position is ∼870 K. An X-ray jet is aligned with the ionization cones and associated with high-excitation emission lines of [Si vi] in a coronal line region extending 300 pc from the nucleus. Molecular hydrogen is spatially independent of the cones, concentrated in a disk equatorial to the SF ring, but also showing entrainment along the sides of the bicone. Gas masses for warm and cold H2, H i, and H ii are estimated, and the excitation mechanisms for ionized and molecular gas are elucidated, from both optical (which shows a clean SF–AGN mixing sequence) and infrared diagnostics (which show more complicated, multicomponent excitation regimes).
AGN Evolution from the Galaxy Evolution Viewpoint. II.
Authors: Caplar Neven , Lilly Simon J. , Trakhtenbrot Benny
Published: November 2018

In order to relate the observed evolution of the galaxy stellar mass function and the luminosity function of active galactic nuclei (AGNs), we explore a coevolution scenario in which AGNs are associated only with the very last phases of the star-forming life of a galaxy. We derive analytically the connections between the parameters of the observed quasar luminosity functions and galaxy mass functions. The (m
bh/m
*)Qing associated with quenching is given by the ratio of the global black hole accretion rate density (BHARD) and star formation rate density (SFRD) at the epoch in question. Observational data on the SFRD and BHARD suggest (m
bh/m
*)Qing ∝ (1 + z)1.5 below redshift 2. This evolution reproduces the observed mass–luminosity plane of Sloan Digital Sky Survey quasars, as well as the local m
bh/m
* relation in passive galaxies. The characteristic Eddington ratio, λ*, is derived from both the BHARD/SFRD ratio and the evolving L* of the AGN population. This increases up to z ∼ 2 as λ* ∝ (1 + z)2.5, but at higher redshifts, λ* stabilizes at the physically interesting Eddington limit, λ* ∼ 1. The new model may be thought of as an opposite extreme to our earlier coevolution scenario in Caplar et al. The main observable difference between the two coevolution scenarios, presented here and in Caplar et al. is in the active fraction of low-mass star-forming galaxies. We compare the predictions with the data from deep multiwavelength surveys and find that the “quenching” scenario developed in the current paper is preferred.
The Turbulent Cascade for High Cross-helicity States at 1 au. II. Minor Energy
Authors: Vasquez Bernard J. , Forman M. A. , Coburn J. T. , Smith C. W. , Stawarz J. E.
Published: November 2018

The application of third moments to turbulence can determine the rate of the energy cascade. This approach is most readily done for statistically homogeneous turbulence in a uniform incompressible medium. Solar wind conditions near 1 au appear to fulfill these requirements sufficiently well to demonstrate that an energy cascade is active among interplanetary fluctuations with a rate sufficient for the inferred amount of proton heating. Fluctuation and solar-wind parameter ranges have been found where average cascade rates are calculated to have negative values that correspond to back-transfer of energy implying no proton heating. Additionally, individual outward and inward pseudo-energy cascade rates are anti-correlated rather than correlated, as they are for a power spectral cascade rate prediction. These negative rates and behaviors are shown here to be organized by inward pseudo-energy, which is generally the minor component of energy, and they occur below a threshold of inward pseudo-energy per unit mass of about 800 km2 s−2 for 12 hr intervals. Inward pseudo-energy is also shown to correlate with ambient solar-wind intervals that have decreasing wind speed and so correspond to rarefactions. These results imply that the average negative cascade rates may be the outcome of effects that are significant enough in these rarefactions to require a third-moment analysis that includes the effects of a nonuniform medium, principally flow gradients.

Authors: Hangody László , Kish Gary , Kárpáti Zoltán , Udvarhelyi Iván , Szigeti István , Bély Miklós
Published: November 2018

ABSTRACT

This article describes a one-step operative technique for the treatment of circumscript cartilage defects of weight-bearing surfaces of the knee. Since 1992, a total of 227 patients were treated using this technique for full-thickness lesions resulting from chondropathy, traumatic chondral defects, and osteochondritis dissecans; the procedure was evaluated in 57 patients who had >3 years of follow-up. Magnetic resonance imaging, computed tomography arthrographies, ultrasound, and arthroscopy were used to evaluate the technique. Using the modified Hospital for Special Surgery (HSS) knee scoring system, 91% of the patients achieved a good or excellent result. The operative technique, clinical results, and complications are detailed.
Linking trawl fleet dynamics and the spatial distribution of exploited species can help to avoid unwanted catches: the case of the NW Mediterranean fishing grounds
Authors: Garcia-de-Vinuesa Alfredo , Sola Iván , Quattrocchi Federico , Maynou Francesc , Demes Montserrat
Published: November 2018

With the full implementation of the landing obligation on 1 January 2019, In European waters it will become mandatory for the trawling fleet to land at port all catches of certain species because, according to Article 15 of the new European Common Fisheries Policy, the species subject to the minimum conservation reference size (MCRS) cannot be discarded. Additionally, since 2005, trawlers over 15 m in length are required to carry an onboard vessel monitoring system (VMS), which generates information on fleet dynamics. The objective of this work was to provide a tool for avoiding unwanted catches by integrating the catch study of trawlers operating in the port of Blanes together with VMS data. To achieve this objective, the catches of 40 hauls were monitored, sampled and analysed together with VMS data for the years 2012-2014 integrated in a geographical information system. The results show that specimens below the MCRS were often captured in crinoid aggregation habitats, bottoms with maërl and muddy bottoms that were identified as nursery habitats of commercial species, e.g. Merluccius merluccius, Pagellus spp. and Mullus spp. VMS data showed considerable fishing pressure on areas with maërl and muddy habitats during the recruitment periods of these and other commercially relevant species. Implementing spatial or seasonal closures in habitats where species regulated by the MCRS are subject to catches could be a useful tool for preventing unwanted catches.
Rediscovering Phoenicians in their Homeland from the Perspective of Iron Age Coroplastic Art
Authors: Bolognani Barbara
Published: November 2018

The collective imagery of the Phoenicians is well known both within and outside of the academic world in large part because of the representations of daily life in their coroplastic art. Yet, there still is no comprehensive study of this genre of their material culture. In this brief communication, a new research project is presented that concerns a regional survey of Iron Age clay figurines from Phoenician sites in the eastern Mediterranean. The sites included in this research range beyond the borders traditionally ascribed to the Phoenicians, and cover the entire Syrian, Lebanese, and Israeli coasts. This research aims to illustrate the regional distribution of these figurines, including their production centers, as well as their types, uses, chronologies, and the meanings of this class of artefacts.

Performance of Memory Virtualization Using Global Memory Resource Balancing
Authors: Gangadhar Pvss , Hota Ashok Kumar , Rao Mandapati Venkateswara , Rao Vedula Venkateswara
Published: November 2018

Virtualization has become a universal generalization layer in contemporary data centers. By multiplexing hardware resources into multiple virtual machines and facilitating several operating systems to run on the same physical platform at the same time, it can effectively decrease power consumption and building size or improve security by isolating virtual machines. In a virtualized system, memory resource supervision acts as a decisive task in achieving high resource employment and performance. Insufficient memory allocation to a virtual machine will degrade its performance drastically. On the contrasting, over allocation reasons ravage of memory resources. In the meantime, a virtual machine's memory stipulates may differ drastically. As a consequence, effective memory resource management calls for a dynamic memory balancer, which, preferably, can alter memory allocation in a timely mode for each virtual machine-based on their present memory stipulate and therefore realize the preeminent memory utilization and the best possible overall performance. Migrating operating system instances across discrete physical hosts is a helpful tool for administrators of data centers and clusters: It permits a clean separation among hardware and software, and make easy fault management. In order to approximate the memory, the stipulate of each virtual machine and to adjudicate probable memory resource disagreement, an extensively planned approach is to build an Least Recently Used based miss ratio curve which provides not only the current working set size but also the correlation between performance and the target memory allocation size. In this paper, the authors initially present a low overhead LRU-based memory demand tracking scheme, which includes three orthogonal optimizations: AVL based Least Recently Used association, dynamic hot set sizing. This assessment outcome confirms that, for the complete SPEC CPU 2006 benchmark set, subsequent to pertaining the 3 optimizing techniques, the mean overhead of MRC construction are lowered from 173% to only 2%. Based on current WSS, the authors then predict its trend in the near future and take different tactics for different forecast results. When there is an adequate amount of physical memory on the host, it locally balances its memory resource for the VMs. Once the local memory resource is insufficient and the memory pressure is predicted to sustain for a sufficiently long time, VM live migration, is used to move one or more VMs from the hot host to other host(s). Finally, for transient memory pressure, a remote cache is used to alleviate the temporary performance penalty. These experimental results show that this design achieves 49% center-wide speedup.

Authors: AMARAL Bárbara GONÇALVES DO , ENSSLIN SANDRA ROLIM , VALMORBIDA SANDRA MARA IESBIK , DUTRA ADEMAR
Published: November 2018

No contexto da Nova Gestão Pública, encontram-se os servidores públicos como agentes centrais na consecução dos objetivos da organização pública e na oferta de bens e serviços à sociedade. Portanto, as entidades públicas se defrontam com o desafio de potencializar e gerenciar seus colaboradores de forma estratégica. A fim de explorar as competências que agregam valor, o gerenciamento do desempenho individual contribuirá para o desempenho organizacional. Considerando que a gestão de Recursos Humanos envolve, entre outras funções, o desenvolvimento de Sistemas para avaliar o desempenho dos servidores, fazer uso dos insights da área de Avaliação de Desempenho Organizacional pode contribuir para o sucesso dessa função. Assim, o presente artigo tem por objetivo investigar as pesquisas científicas, em língua inglesa, sobre Avaliação de Desempenho do Servidor Público, salientando as lacunas e oportunidades de pesquisa com base nos resultados das análises bibliométrica e sistêmica. Para alcançar tal objetivo, adotou-se o ProKnow-C como instrumento de intervenção. Com base nesse instrumento, selecionaram-se 23 artigos entre 2000 e 2017, os quais foram analisados pela afiliação teórica de Ensslin et al. (2010), focando exclusivamente nas Lentes da Abordagem, Singularidade e Identificação dos Objetivos. Constatou-se a necessidade de (i) explorar a área de gestão de pessoas no setor público; (ii) desenvolver modelos nas entidades públicas sob o viés Construtivista; e (iii) ampliar a rede de colaboração e estudos de caso que demonstrem a aplicação de modelos da Avaliação de Desempenho.
CONTRIBUIÇÃO AO ESTUDO DO CARÁTER DAS DECISÕES E AÇÕES DOS COLONIZADORES PIONEIROS DE CIDADE GAÚCHA, ESTADO DO PARANÁ
Authors: Gomes Valdir , Santos Manoel Luiz dos
Published: November 2018

O trabalho teve por objetivo compreender a natureza conceitual do pensamento e do conhecimento que fundamentaram as práticas e o papel dos homens como agentes geográficos intervencionistas, para uso e ocupação do solo do município de Cidade Gaúcha, no Noroeste do Estado do Paraná, durante a década de 1950, em suas relações com o processo de ocupação e uso do solo. Em complemento, buscou-se identificar se o processo ocorreu em conformidade com os dispositivos legais sobre a matéria vigentes à época. A pesquisa enquadra-se na classe dos estudos de caso e de caráter qualitativo, sendo que na análise utilizou dados secundários do IBGE e IPARDES, e dados primários obtidos por meio de entrevistas com colonizadores pioneiros. O resultado do estudo mostrou que os mesmos não possuíam conhecimento do código florestal vigente à época, assim como se apresentava uma completa ausência dos agentes do poder público no cotidiano do processo. Esses fatos permitiram também concluir que as decisões e ações dos agentes colonizadores foram baseadas no isomorfismo mimético.

Authors: Lebbos Favoreto Ricardo , Amâncio-Vieira Saulo Fabiano , Spiri Ferreira Thiago
Published: November 2018

A associação entre aspectos organizacionais internos e vantagem competitiva é central à teoria dos recursos. Como no campo da estratégia em geral, boa parte das pesquisas empíricas da teoria dos recursos é conduzida com organizações de grande porte. Considerando-se que especificidades relativas ao porte podem demandar construções teóricas específicas, objetiva-se neste artigo analisar o comportamento estratégico de empresas de médio porte pela via dos seus aspectos organizacionais internos. As análises conectam aspectos organizacionais internos às práticas estratégicas perpetradas pelas empresas. Trata-se de estudo longitudinal multicaso, em que se exploram dados de três incorporadoras imobiliárias familiares. A busca por elementos comuns aos casos permitiu a detecção de quatro ocorrências internas principais e seis práticas estratégicas correntes. Os resultados sugerem a importância de levar em conta as peculiaridades relativas ao porte para compreender o comportamento estratégico. No fim do trabalho, apresentam-se quatro proposições substantivas que, associando estratégia, aspectos internos e características do porte organizacional, oferecem possibilidades explicativas para o comportamento estratégico das empresas estudadas.

Arctic cloud cover bias in ECHAM6 and its sensitivity to cloud microphysics and surface fluxes

Published: November 2018

Abstract. Among the many different feedback mechanisms contributing to the Arctic Amplification, clouds play a very important role in the Arctic climate system through their cloud radiative effect. It is therefore important that climate models simulate basic cloud properties like cloud cover and cloud phase correctly. We compare results from the global atmospheric model ECHAM6 to observations from the CALIPSO satellite active lidar instrument using the COSP satellite simulator. Our results show that the model is able to reproduce the spatial distribution and cloud amount in the Arctic to some extent, but that cloud cover has a positive bias (caused by an overestimation of low-level, liquid containing cloud) in regions where the surface is covered by snow or ice. We explored the sensitivity of cloud cover to the strength of surface heat fluxes, but only by increasing surface mixing the observed cloud cover bias cloud be reduced. As ECHAM6 already mixes too strongly in the Arctic, the cloud cover bias can mainly be attributed to cloud microphysical processes. Improvements in the phase partitioning of Arctic low-level clouds could be achieved by a more effective Wegener–Bergeron–Findeisen process but total cloud cover remained still overestimated. By allowing for a slight supersaturation with respect to ice within the cloud cover scheme, we were able to also reduce this positive cloud cover bias.

Abstract. Diatoms tend to dominate the Arctic spring bloom, a key event in the ecosystem. Large sinking of diatoms is expected at the end of the bloom driven by deteriorated cell status associated to nutrients (silicon) depletion. However, there are few reports on the status of diatoms' health during Arctic blooms and its possible role on sedimentary fluxes. Here we quantify, using the Bottle-Net, Arctic diatom stocks below and above the photic layer and assess their cell health status. The communities were sampled around the Svalbard Islands and encompassed a broad diversity of conditions and bloom stages. About 1/4 (mean±SE 24.2 ± 6.7 %) of the total water column (max. 415 m) diatom stock was found below the photic layer, indicating significant sinking of diatoms in the area. The fraction of living diatom cells in the photic layer averaged 59.4 ± 6.3 % but showed the highest percentages (72.0 %) in stations supporting active blooms. In contrast, populations below the photic layer were dominated by dead cells (20.8 ± 4.9 % living cells). The percentage of diatom’s stock found below the photic layer was negatively related to the percentage of living diatoms in the surface, indicating that healthy populations remained in the surface layer. An experiment on board in a tall (1.35 m) sedimentation column confirmed that dead diatom cells from the Arctic community sink faster that living ones. Also, diatoms cell mortality increased in darkness, showing an averaged half life of 1.025 ± 0.075 d−1. The results conform to a conceptual model where diatoms grow during the bloom until silicic acid stocks are depleted, and support a link between diatom cell health status and sedimentation fluxes in the Arctic. Healthy arctic phytoplankton communities remained at the photic layer, whereas dying communities exported a large fraction of the biomass to the aphotic zone, fuelling carbon sequestration and benthic ecosystems.
Link between the North Atlantic Oscillation and the surface mass balance components of the Greenland Ice Sheet under preindustrial and last interglacial climates: a study with a coupled global circulation model
Authors: Ramos Buarque Silvana , Salas y Melia David
Published: November 2018

Abstract. The relationship between the surface mass balance (SMB) components
(accumulation and melting) of the Greenland Ice Sheet (GrIS) and the North
Atlantic Oscillation (NAO) is examined from numerical simulations performed
with a new atmospheric stretched grid configuration of the Centre National de
Recherches Météorologiques Coupled Model (CNRM-CM) version 5.2 under
three periods: preindustrial climate, a warm phase (early Eemian,
130 ka BP) and a cool phase (late Eemian, 115 ka BP) of the last
interglacial. The horizontal grid of the atmospheric component of CNRM-CM5.2
is stretched from the tilted pole on Baffin Bay (72∘ N,
65∘ W) in order to obtain a higher spatial resolution on Greenland.
The correlation between simulated SMB anomalies averaged over Greenland and
the NAO index is weak in winter and significant in summer (about 0.6 for the
three periods). In summer, spatial correlations between the NAO index and SMB
components display different patterns from one period to another. These
differences are analyzed in terms of the respective influence of the positive
and negative phases of the NAO on accumulation and melting. Accumulation in
south Greenland is significantly correlated with the positive (negative)
phase of the NAO in a warm (cold) climate. Under preindustrial and
115 ka BP climates, melting along the margins is more correlated with the
positive phase of the NAO than with its negative phase, whereas at
130 ka BP it is more correlated with the negative phase of the NAO in north
and northeast Greenland.

Abstract. We detail a new prediction-oriented procedure aimed at volcanic hazard assessment based on geophysical mass flow models constrained with heterogeneous and poorly defined data. Our method relies on an itemized application of the empirical falsification principle over an arbitrarily wide envelope of possible input conditions. We thus provide a first step towards a objective and partially automated experimental design construction. In particular, instead of fully calibrating model inputs on past observations, we create and explore more general requirements of consistency, and then we separately use each piece of empirical data to remove those input values that are not compatible with it, hence defining partial solutions to the inverse problem. This has several advantages compared to a traditionally posed inverse problem: (i) the potentially non-empty inverse images of partial solutions of multiple possible forward models characterize the solutions to the inverse problem; (ii) the partial solutions can provide hazard estimates under weaker constraints, potentially including extreme cases that are important for hazard analysis; (iii) if multiple models are applicable, specific performance scores against each piece of empirical information can be calculated. We apply our procedure to the case study of the Atenquique volcaniclastic debris flow, which occurred on the flanks of Nevado de Colima volcano (México), 1955. We adopt and compare three depth averaged models currently implemented in the TITAN2D solver, available from vhub.org. The associated inverse problem is not well-posed if approached in a traditional way. We show that our procedure can extract valuable information for hazard assessment, allowing the exploration of the impact of synthetic flows similar to those that occurred in the past, but different in plausible ways. The implementation of multiple models is thus a crucial aspect of our approach, as they can allow the covering of other plausible flows. We also observe that model selection is inherently linked to the inversion problem.
