Published: July 2017

Abstract. Enhanced deposition of atmospheric nitrogen (N) resulting from anthropogenic activities has negative impacts on plant diversity in ecosystems. Several mechanisms have been proposed to explain the species loss. Ion toxicity due to N deposition-induced soil acidification has been suggested to be responsible for species loss in acidic grasslands, while few studies have evaluated the role of soil-mediated homeostasis of ions in species loss under elevated N deposition in grasslands with neutral or alkaline soils. To determine whether soil-mediated processes are involved in changes in biodiversity induced by N deposition, the effects of 9-year N addition on soil properties, aboveground biomass (AGB) and species richness were investigated in an Inner Mongolia steppe. Low to moderate N addition rate (2, 4, 8 g N m−2 yr−1) significantly enhanced AGB of graminoids, while high N addition rate (≥ 16 g N m−2 yr−1) reduced AGB of forbs, leading to an overall increase in AGB of the community under low to moderate N addition rates. Forb richness was significantly reduced by N addition at rates greater than 8 g N m−2 yr−1, while no effect of N addition on graminoid richness was observed, resulting in decline in total species richness. N addition reduced soil pH, depleted base cations (Ca2+, Mg2+ and K+) and mobilized Mn2+, Fe3+, Cu2+ and Al3+ ions in soils. Soil inorganic-N concentration was negatively correlated with forb richness and biomass, explaining 23.59% variation of forb biomass. The concentrations of base cations (Ca2+ and Mg2+) and metal ions (Mn2+, Cu2+ and, Fe3+) showed positively and negatively linear correlation with forb richness, respectively. Changes in the metal ion concentrations accounted for 42.77% variation of forb richness, while reduction of base cations was not associated with the reduction in forb richness. These results reveal that patterns of plant biodiversity in the temperate steppe of Inner Mongolia are primarily driven by increases in metal ion availability, particularly enhanced release of soil Mn2+.

Abstract. The Laptev and East Siberian seas are the least biologically studied region in the Arctic Ocean, although they are highly dynamic in terms of active processing of organic matter impacting the transport to the deep Arctic Ocean. Field-measured carbon and nitrogen uptake rates of phytoplankton were conducted in the Laptev and East Siberian seas as part of the NABOS (Nansen and Amundsen Basins Observational System) program. Major inorganic nutrients were mostly depleted at 100–50 % light depths but were not depleted within the euphotic depths in the Laptev and East Siberian seas. The water column-integrated chl-a concentration in this study was significantly higher than that in the western Arctic Ocean (t-test, p > 0.01). Unexpectedly, the daily carbon and nitrogen uptake rates in this study (average ± S.D. = 110.3 ± 88.3 mg C m−2 d−1 and 37.0 ± 25.8 mg N m−2 d−1, respectively) are within previously reported ranges. Surprisingly, the annual primary production (13.2 g C m−2) measured in the field during the vegetative season is approximately one order of magnitude lower than the primary production reported from a satellite–based estimation. Further validation using field-measured observations is necessary for a better projection of the ecosystem in the Laptev and East Siberian seas responding to ongoing climate change.
Entschärfte Säkularisierung – gezähmte Religiosität – (multi-)religiöse Räume als räumliche Materialisierungen der Postsäkularisierung
Authors: Duttweiler Stefanie
Published: July 2017

Abstract. Ausgangsannahme dieses Beitrags ist die architektursoziologische Prämisse, Architektur sei wesentlich an der Gestalt und Gestaltung des Sozialen beteiligt. Dementsprechend versteht der Beitrag multireligiöse Räume in nicht-religiösen Kontexten als materialisierten und verdichteten Ausdruck des religiösen und gesellschaftlichen Wandels. Durch die räumliche Verortung, die architektonische Gestaltung, die diskursiven Plausibilisierungen und Legitimierungen sowie die Nutzung der religiösen Räume wird die veränderte, postsäkulare Beziehung zwischen Religion und Gesellschaft verhandelt, transformiert und stabilisiert. Die spezifischen Herausforderungen, die sich für diese religiösen Räume ergeben, und die gestalterischen Antworten auf diese Herausforderungen entspezifizieren dabei sowohl Religion als auch Gesellschaft: Sie „entschärfen‟ Säkularisierung und sie „zähmen‟ Religion.

Abstract. This paper describes the next generation ocean forecast model for the European North West Shelf, which will become the basis of operational forecasts in 2018. This new system will provide a step change in resolution, and therefore our ability to represent small scale processes. The new model has a resolution of 1.5 km, compared with a grid spacing of 7 km in the current operational system. AMM15 (Atlantic Margin Model, 1.5 km) is introduced as a new regional configuration of NEMO v3.6. Here we describe the technical details behind this configuration, with modifications appropriate for the new high resolution domain. Results from a 30 year non-assimilative run, using the AMM15 domain, demonstrate the ability of this model to represent the mean state and variability of the region. Overall, there is an improvement in the representation of the mean state across the region, suggesting similar improvements may be seen in the future operational system. However, the reduction in seasonal bias is greater off-shelf than on-shelf. In the North Sea, biases are largely unchanged. Since there has been no change to the vertical resolution or parameterisation schemes, performance improvements are not expected in regions where stratification is dominated by vertical processes, rather than advection. This highlights the fact that increased horizontal resolution will not lead to domain-wide improvements. Further work is needed to target bias reduction across the North West Shelf region.

Este estudo discute as relações entre o mal--estar dos profissionais da educação e a psicossomática expressa no corpo como espaço de simbolização dos problemas enfrentados pelos professores da rede pública estadual, na região do Planalto Médio do Rio Grande do Sul. Os objetivos foram: verificar partes do corpo e idade mais vulneráveis dos professores e interpretar o simbolismo desses problemas de saúde em relação aos aspectos pessoais e profissionais. A pesquisa caracterizou-se pela abordagem qualitativa de cunho hermenêutico. Os participantes da investigação foram classificados pelas idades, de acordo com a divisão da Organização Mundial da Saúde e pelas partes do corpo afetadas. O texto traz como resultados a identificação dos problemas de saúde traumatológicos e ortopédicos, principalmente em membros inferiores, entre 46 e 60 anos de idade e o simbolismo desses problemas de saúde. No que diz respeito ao aspecto profissional, tais problemas decorrem da interação na escola, onde sofrem pressão emocional, têm excesso de trabalho e grande mobilidade, o que gera altos níveis de estresse; a problemática do mal-estar docente nos seus aspectos psicossomáticos e a necessidade de um sistema multiprofissional de apoio ao docente.
OS ÍCONES E SEUS SIGNOS: A APLICABILIDADE DAS IMAGENS NAS PESQUISAS E ESTUDO DA HISTÓRIA DO IMPÉRIO BIZANTINO
Authors: Tamanini Paulo Augusto
Published: July 2017

O estudo das imagens tende a circunstanciar informações que reverbera em um campo de abordagens multifacetado, aberto à estranheza da História. Quando o objeto em análise trata de um conjunto de ícones bizantinos, parece natural reportá-lo aos assuntos de Teologia, negando a possibilidade de a História também sobre ele arguir, discorrer e tecer seus pareceres. Contrariando esta tendência, este artigo aborda os ícones bizantinos em sua historicidade, em sua feitura estética e diálogo com a Teologia da Igreja Ortodoxa Oriental. Por receber influências dessas áreas do saber, a abordagem é pensada transdisciplinarmente, usando como ponto de partida o conceito de signo pensado por Gilles Deleuze. Quer igualmente contribuir em alguns pontos teóricos acerca do uso das imagens bizantinas na construção da narrativa historiográfica.
O LIVREIRO QUE PREFACIAVA (E OS LIVROS ROUBADOS); OS PREFÁCIOS DE FRANCISCO ROLLAND E A CIRCULAÇÃO DE LIVROS NO IMPÉRIO PORTUGUÊS AO FIM DO SÉCULO XVIII
Authors: DeNipoti Claudio
Published: July 2017

Este artigo percorre os escritos do livreiro e impressor francês radicado em Lisboa, Francisco Rolland, que escrevia paratextos para suas edições, na forma de prefácio, avisos ao leitor e notícias, nas quais elabora padrões discursivos relativos às questões fundamentais do mercado de livros português do fim do século XVIII: a utilidade, a necessidade, a instrução e o serviço ao império. Simultaneamente, Rolland era um comerciante hábil e perceptivo, que sabia circular entre os letrados portugueses, buscando antecipar gostos e demandas livreiras, ao mesmo tempo que se via às voltas com os mecanismos de censura para publicar e circular seus livros. Este estudo tenta compreender a atuação deste agente do livro, no contexto mais complexo da ilustração lusitana.
MELANCOLIA E ALTERIDADE NOS TRISTES TRÓPICOS BRASILEIROS: CLAUDE LÉVI-STRAUSS LEITOR DE JEAN DE LÉRY
Authors: Torrão Filho Amilcar
Published: July 2017

Em 1955 Claude Lévi-Strauss publica seu Tristes Tropiques, um livro de “anti-viagem”, que, entretanto, segue os passos do relato de Jean de Léry, Histoire d’un voyage faict en la terre du Brésil, de 1578, seu breviário do etnógrafo. Considerado por ele o primeiro, senão também o último etnógrafo, o que viu a um Paraíso em seus últimos momentos antes da destruição, Lévi-Strauss herda de Léry a visão melancólica do encontro entre culturas.

Authors: Mota André
Published: July 2017

O artigo em pauta estuda a constituição do Serviço de Pronto Socorro do Hospital das Clínicas de São Paulo. Criado em 1944 como resposta às demandas vividas pela cidade, a partir da explosão populacional advinda do processo migratório entre os anos de 1930-1950, o Serviço teve que lidar com os contratempos trazidos, tanto pela administração municipal e seu gerenciamento no campo hospitalar, como as próprias contradições de uma cidade em franca expansão populacional e sem controle. Nesse sentido, busca-se apresentar o projeto arquitetado e formulado pelos professores da Faculdade de Medicina USP, bem como a indicação de tais contratempos em seus primeiros anos, formulada pelo Hospital das Clínicas como também pelas notícias da imprensa local, envolvendo a complexidade da assistência hospitalar da capital paulistana.

Authors: Borges Viviane Trindade
Published: July 2017

O presente artigo analisa a patrimonialização de memórias, acervos e edifícios ligados a história das prisões brasileiras. Tratarei da ausência de tombamentos em nível Federal e da destruição de edificações carcerárias que datam do século XX, período em que o Brasil viveu um verdadeiro boom na construção de presídios e penitenciárias. Paralelo ao descaso em relação aos edifícios, é possível observar inciativas que visam a preservação do patrimônio carcerário em sua dupla dimensão: material e imaterial. Nesta perspectiva, serão analisados alguns casos emblemáticos, como o Presídio de Tiradentes, em São Paulo e a Penitenciária de Florianópolis, em Santa Catarina.

Published: July 2017

It has been known that the use of self-selected topic enhances students’ writing achievement. It is also known thatpeer feedback helps improve students’ writing achievement. However, research investigating self-selected topic incombination with peer feedback is a rare undertaking. Therefore, this study aimed to investigate the effect ofself-selected topic and checklist-based peer feedback on the writing ability of students of English as a foreignlanguage (EFL). This study involved 68 eleven-grade students of Multimedia Program of a Vocational High Schoolat Malang, a city in the Province of East Java, Indonesia. Two intact classes assigned to be experimental and controlgroups. The experimental group received treatment of self-selected topic and checklist-based peer feedback, whilethe control group did not. Pre-test and post-test were administered in the form of writing tests to both groups and theresults of those tests were analyzed by using independent sample t-Test to know the effect of the treatment. Theresults showed that the students taught to write with self-selected topic and checklist-based peer feedbackoutperformed those taught without using self-selected topic and checklist-based peer feedback. Accordingly, it isrecommended that English teachers consider assigning the students to write a topic of their own and usingchecklist-based peer feedback.
Authentic Teaching Opportunities of English for Primary Students as a Community of Practice: A Case of Pre-service Teacher Education at a Japanese University
Authors: Okumura Shinji
Published: July 2017

This case study explored what pre-service teachers learned through authentic experiences of English teaching forprimary students, drawing upon the concept of a Community of Practice. A total of 21 pre-service teachers engagedin the training project—including planning, preparing, and teaching lessons—and wrote reflection papers afterthinking about their activities. The focal data was the pre-service teachers’ written work, which was analyzed with aqualitative approach. Follow-up interviews were conducted for selected pre-service teachers. The findings indicatedthat the project contributed to allowing the pre-service teachers to develop knowledge and skills for primary Englisheducation. The study also confirmed that the training project promoted solidarity, especially between the old-timersand the newcomers. On the other hand, the typical Japanese school culture seemed to function as an obstacle toallowing the old-timers and the newcomers to become acquainted enough.
The Competitiveness and Complementarities of Agriculture Trade among ASEAN-5 Countries: An Empirical Analysis
Authors: Shaul Hamid Mohammed Faiz , Aslam Mohamed
Published: July 2017

The trade of agriculture products between ASEAN countries has grown rapidly since the establishment of the ASEAN Free Trade Area (AFTA). By using the Revealed Comparative Advantage (RCA) and Intra-Industry Trade (IIT) indexes, this study empirically analyses the competitiveness and complementarities among the ASEAN-5 countries for agriculture products. The results shows that IIT is relatively limited and RCA for Thailand, Indonesia and Vietnam revealed intense competition among each other in the agriculture sector. Interestingly, the results also showed that Vietnam strongly competed against Thailand and Indonesia, which was detrimental towards both these countries and resulted to these countries losing their competitiveness in several product categories. ASEAN-5 countries have also shown diverse trends of competitiveness for each product category in the agriculture industry and the level of competitiveness coupled with low intra-industry trade reflect that there are policy mismatches that curb further trade integration in the industry despite several efforts under AFTA.
Recognition of Facial Expressions using Local Mean Binary Pattern
Authors: Goyani Mahesh M , Patel Narendra
Published: July 2017

In this paper, we propose a novel appearance based local feature extraction technique called Local Mean Binary Pattern (LMBP), which efficiently encodes the local texture and global shape of the face. LMBP code is produced by weighting the thresholded neighbor intensity values with respect to mean of 3 x 3 patch. LMBP produces highly discriminative code compared to other state of the art methods. The micro pattern is derived using the mean of the patch, and hence it is robust against illumination and noise variations. An image is divided into M x N regions and feature descriptor is derived by concatenating LMBP distribution of each region. We also propose a novel template matching strategy called Histogram Normalized Absolute Difference (HNAD) for comparing LMBP histograms. Rigorous experiments prove the effectiveness and robustness of LMBP operator. Experiments also prove the superiority of HNAD measure over well-known template matching methods such as L2 norm and Chi-Square measure. We also investigated LMBP for facial expression recognition low resolution. The performance of the proposed approach is tested on well-known datasets CK, JAFFE, and TFEID.
Percibir, comprender y sentir. La accesibilidad de los sitios paleolíticos
Authors: Ruiz Zapatero Gonzalo
Published: July 2017

El ensayo presenta una síntesis sobre los modelos de presentación pública de sitios paleolíticos. A lo largo del texto son abordadas diversas cuestiones considerando los destinatarios de los yacimientos arqueológicos y presentando una reflexión sobre los criterios que definen la accesibilidad integral (física y mental) de los sitios. En el cuerpo central analiza el proceso que lleva de la excavación a las (re)presentaciones de los sitios, explorando la idea de la intervención arqueológica como apocatástasis histórica (regresión al origen) y la función de algunos yacimientos como “lugares de memoria”. La última cuestión gira en torno a los valores de los sitios paleolíticos que, en definitiva son los que justifican plenamente las (re)presentaciones que de ellos se realizan.
Habitants de la terra dels dòlmens: de l’espai emocional a la construcció de l’espai públic
Authors: Artillo José Ignacio
Published: July 2017

Explicava el premi Nobel irlandès Seamus Heaney que de petit li agradava veure els grans com recollien amb una galleda l’aigua d’un pou que hi havia al mig dels camps. Observava sempre amb tensió i misteri la cançó repetida de la vella corriola que anava girant amb lentitud, i la corda que descendia cap a la foscor, per després pujar, fins que apareixia la galleda ballant suaument, suspesa en l’aire, i vessant gotes d’aigua al seu voltant. Aquest pou estava en un turó que baixava suaument fins al poble, i on s’alçaven dòlmens i pedres mil·lenàries, restes arqueològiques que eren solament una mínima part del que ocultava el prat verd; per la qual cosa sempre pensava que aquesta aigua que després beurien, venia fresca oferta pels avantpassats dels avantpassats, bàlsam per a l’ànima i la memòria que creuava des de l’origen dels temps. Passats els anys va aprendre i va sentir per primera vegada a la universitat la paraula grega omphalos, que significa melic; i la seva sonoritat, lletrejada de manera lenta i espaiada, una vegada i una altra, li va retornar el so de la corriola girant, i la galleda baixant des de les entranyes de la roca i l’ésser del seu poble.Om-pha-los, om-pha-los, om-pha-los... Melic, l’aigua que ens connecta a través del seu curs alhora fosc i lluminós, amb la nostra existència col·lectiva. Els habitants de terra de dòlmens vivim vinculats íntimament al curs de la memòria que transcorre sota terra, a la llum revelada de la matèria original; la pedra, els metalls, el corall, aigua que raja de la profunditat per nodrir-nos i satisfer de sentit i emoció el nostre present.Aquí tenim la sorpresa, l’emoció. I l’emoció activa la nostra capacitat per trobar-nos i organitzar la tasca comuna de protecció i defensa d’una cosa tan valuosa com els nostres somnis. Aquesta ha estat la nostra experiència al territori de Valencina-Guzmán. Vivim en el món d’avui la contradicció entre la convocatòria universal a participar en l’espai públic i la fragmentació dels interessos i discursos, la coexistència en tots els nivells de la vida quotidiana de processos que ens vinculen i fan interdependents, juntament amb la perduració de diferències que semblen insuperables. L’espai públic és l’àmbit en què organitzem la nostra experiència col·lectiva; és on els membres d’una societat produeixen una realitat comuna, com a ciutadans plens, més enllà de la seva condició de consumidors, electors, creients, experts, i assagen una integració, un reconeixement en termes de compatibilitat que permet defensar el que és nostre, i generar propostes que milloren la vida quotidiana i eixamplen les possibilitats del seu entorn material i emocional.
Caracterització i procedència de les matèries primeres lítiques del sepulcre col·lectiu de Forat de Conqueta
Authors: Pizarro Jezabel , Mora Rafael , Benito-Calvo Alfonso
Published: July 2017

La caracterització de primeres matèries lítiques i la determinació de les àrees de procedència han permès avaluar les estratègies de captació i gestió dels recursos lítics que es van utilitzar al Forat de Conqueta. La caracterització dels materials ha estat realitzada a partir de caràcters macroscòpics. La primera matèria amb un índex més elevat de representativitat és el sílex, seguida de les dolerites. Els resultats obtinguts mostren dues estratègies diferents de captació que corresponen als dos moments d’us de la cavitat. D’una banda, el registre del nivell 1/2 correspondria a una estratègia de captació local i expeditiva. De l’altra, el registre del nivell 3 presenta una aportació de matèria al·lòctona superior a la local.

Aquest text presenta el programa de datacions radiocarbòniques realitzat per al Forat de Conqueta. La metodologia emprada ha estat la datació sobre col·lagen extret de la dentina de restes humanes. Les datacions obtingudes mostren un ús funerari molt perllongat que abraçaria més de dos mil anys. En termes de periodització cultural, l’ús funerari del Forat de Conqueta s’iniciaria en el neolític final i s’estén fins al bronze. La pervivència del mateix tipus de ritual al llarg d’aquesta franja cronològica indica l’alt grau d’arrelament d’unes mateixes poblacions en un territori específic i del seu conservadorisme cultural.

Aquest article presenta l’estudi paleoantropològic i palelopatològic de les restes humanes recuperades al jaciment de Forat de Conqueta. És una cova d’enterrament col·lectiu, d’ús diacrònic, amb enterraments successius, durant un dilatat període de temps. El ritual està caracteritzat per una cremació que, juntament amb els processos postdeposicionals de la cova, facilita el mal estat de conservació. El mínim d’individus enterrats calculat a partir de l’estudi ossi és de 37 individus. La presència d’algunes connexions anatòmiques i la possible associació d’alguns ossos per criteris morfològics, tafonòmics, paleopatològics, mètrics, etc., ha permès entendre la dinàmica tafonòmica de la cova.

Interactive, Web-Based Calculator of Neutron and X-ray Reflectivity
Authors: Maranville Brian B
Published: July 2017

For many users of the neutron and X-ray reflectometry instruments at NIST, these measurements represent a relatively small and specialized part of their research portfolio. As such, providing calculation and modeling tools that are as accessible and easy-to-use as possible is a high priority of the facility. In order to meet this need, a purely web-browser-based calculator for reflectivity modeling and rudimentary fitting has been developed and provided on a publicly accessible web server.
Going to https://www.ncnr.nist.gov/instruments/magik/calculators/reflectivity-calculator.html, will load a one-page web application into the browser. Any relatively modern browser with support for ECMAScript 5 will be able to load and run the application. A calculator for magnetic samples can be found at https://www.ncnr.nist.gov/instruments/magik/calculators/magnetic-reflectivity-calculator.html.

À travers une mise en contexte historique qui relève les interactions entre l’évolution technologique, les impératifs commerciaux et la dynamique de récompense dans les jeux, le sens de cette mise à mort se précise : le jeu semble proposer une critique des fantasmes de puissance androcentrés et hétéronormatifs qui se déployaient sur les écrans vidéoludiques au tournant des années 1990.

Cet article aborde plusieurs aspects ayant trait à la mort vidéoludique au coeur de l’expérience de deux jeux vidéo indépendants, soit Hotline Miami (Sodestrom et Wedin, 2012) et Binding of Isaac (McMillen et Himsl, 2011). Les deux titres étudiés s’appuient sur des mécaniques de jeu spécifiquement liées à la mort du personnage-joueur afin de conduire à des formes d’apprentissage distinctes ayant trait au rapport à l’espace et à la prise de risque, engendrant des cas de frustration qui contribuent à l’immersion vidéoludique. Nous conclurons en abordant la valeur de témoignage rattachée aux démarches visant à archiver des expériences de jeu liées à la mort vidéoludique.

This article studies the emergence and consolidation of the bookstores in Colombia. Focusing on the first half of the 19th Century, the elements that originated the fairly specialized profession of the booksellers as well as the commercial circulation of books during this period are explored here. This paper argues that the relationship between bookstores and international trade networks was a key element for their organization, always in alignment with changes in the national book market and the local radio of readers. Thus, the paper provides a characterization of the nineteenth-century booksellers, highlighting the commercial role of the catalogues, their shift toward the editorial environment and its connections to the political power.

Introduction: Rapid diagnostic testing has made HIV diagnosis and subsequent treatment more accessible. However, multiple factors, including improper implementation of testing strategies and clerical errors, have been reported to lead to HIV misdiagnosis. The World Health Organization has recommended HIV retesting prior to antiretroviral therapy (ART) initiation which has become pertinent with scaling up of Early Access to ART for All (EAAA). In this analysis, misdiagnosed clients are identified from a subgroup of clients enrolled in EAAA implementation study in Swaziland.

Methods: The subgroup to assess misdiagnosis was identified from enrolled EAAA study clients, who had an undetectable viral load prior to ART initiation between September 1, 2014 and May 31, 2016. One hundred and five of 2533 (4%) clients had an undetectable viral load prior to initiation to ART (pre‐ART). The HIV status of clients was confirmed using the Determine HIV 1/2 and Uni‐Gold HIV 1/2 rapid tests performed serially as recommended by the national testing algorithm. The status of clients on ART was additionally confirmed by fourth‐generation HIV Ag/Ab combo tests, Architect and Genscreen Ultra.

Results: Fourteen of the 105 (13%) clients were false positive (HIV negative) on confirmation testing, of whom five (36%) were still in pre‐ART care, while nine (64%) were in ART care. Overall, proportion of false positive was 0.6% (14/2533). The false‐positive clients had a median CD4 of 791 cells/ml (interquartile range (IQR): 628, 967) compared to 549 cells/ml (IQR: 387, 791) for true positives (HIV positive) (p = 0.0081) and were nearly 20 years older (p = 0.0008).

Conclusions: Overall 0.6% of all enrolled EAAA clients were misdiagnosed, and 64% of misdiagnosed clients were initiated on ART. With adoption of EAAA guidelines by national governments, ART initiation regardless of immunological criteria, strengthening of proficiency testing and adoption of retesting prior to ART initiation would allow identification of misdiagnosed clients and further reduce potential of initiating misdiagnosed clients on ART.
Ion leakage at dayside magnetopause in case of high and low magnetic shears

Published: July 2017

The nature of energetic ions in the magnetosheath of the Earth is studied using the data of the Time History of Events and Macroscale Interactions during Substorms mission. Three intervals of the multiple crossings of the magnetopause during northward orientation of the interplanetary magnetic field and quiet geomagnetic conditions were selected to illustrate the behavior of ion distribution functions near the subsolar region in case of high and low magnetic shears. For all analyzed events, the velocity and thickness of the magnetopause was estimated using the simultaneous measurements in two satellites. The ion spectra in the magnetosphere and magnetosheath were fitted by kappa and bi‐kappa distributions, respectively. It was found that during high shear events the energetic part of the ion spectra is practically identical inside and outside the magnetopause. On the other side, for low shear events the energetic fluxes of ions in the magnetosheath are lower. We argue that in case of high magnetic shear, the magnetopause becomes transparent when the ion Larmor radii is comparable or larger than the thickness of the magnetopause. It may explain coincidence of the energetic part of spectra inside and outside the magnetosphere. We discuss the reason for the changes of spectra at low magnetic shear.
Medium‐scale traveling ionospheric disturbances triggered by Super Typhoon Nepartak (2016)

Published: July 2017

Two remarkable typhoon‐induced traveling ionospheric disturbances (TIDs) with concentric and northwest‐southeast (NW‐SE) alignments, respectively, associated with concentric gravity waves (CGWs) and ionosphere instabilities possibly seeded by CGWs, were observed in total electron content (TEC) derived from ground‐based Global Navigation Satellite System networks in Taiwan and Japan when the Category 5 Super Typhoon Nepartak approached Taiwan on 7 July 2016. The concentric TIDs (CTIDs) first appear with horizontal phase velocities of ~161–200 m/s, horizontal wavelengths of ~160–270 km, and periods of ~15–22 min during 08:00–11:20 UT. Following the CTIDs, the NW‐SE aligned nighttime medium‐scale TIDs (MSTIDs) are formed on the west edge of the CTIDs over the Taiwan Strait during 11:30–14:00 UT. It is suggested that the MSTIDs are produced by the electrodynamical coupling of Perkins instability and CGW‐induced polarization electric fields. This study proposes connections of typhoon‐induced CTIDs and subsequently occurring MSTIDs in the low‐latitude ionosphere.
A case study of microphysical structures and hydrometeor phase in convection using radar Doppler spectra at Darwin, Australia

To understand the microphysical processes that impact diabatic heating and cloud lifetimes in convection, we need to characterize the spatial distribution of supercooled liquid water. To address this observational challenge, ground‐based vertically pointing active sensors at the Darwin Atmospheric Radiation Measurement site are used to classify cloud phase within a deep convective cloud. The cloud cannot be fully observed by a lidar due to signal attenuation. Therefore, we developed an objective method for identifying hydrometeor classes, including mixed‐phase conditions, using k‐means clustering on parameters that describe the shape of the Doppler spectra from vertically pointing Ka‐band cloud radar. This approach shows that multiple, overlapping mixed‐phase layers exist within the cloud, rather than a single region of supercooled liquid. Diffusional growth calculations show that the conditions for the Wegener‐Bergeron‐Findeisen process exist within one of these mixed‐phase microstructures.
Modeling long recovery early events (LOREs) produced by lightning‐induced ionization of the nighttime upper mesosphere
Authors: Kotovsky D. A. , Moore R. C.
Published: July 2017

We present results of a cylindrically symmetric, coupled electrodynamic, and photochemical model which simulates diffuse ionization of the middle atmosphere induced by strong lightning discharges (peak currents >150 kA). Scattering of subionospherically propagating, very low frequency radio waves is then evaluated using the Long‐Wave Propagation Capability code. Some modeled sprite halos exhibit continued electron density growth up to timescales of seconds due to O− detachment, though it is not yet clear how this might relate to the slower onset durations (>20 ms) of some early VLF events. Modeled electron density enhancements in sprite halos, capable of strong VLF scattering, can persist for long periods of time (greater than hundreds of seconds) even at lower altitudes where their recovery is initially controlled by fast attachment processes. Consequently, our modeling results indicate that both typical recovery (20 to 240 s) and long recovery (LOREs, >300 s) VLF scattering events can be explained by scattering from conductivity changes associated with sprite halos. In contrast, modeled scattered fields resulting from elve‐associated conductivity changes, though exhibiting long recovery times, are too weak to sufficiently explain typical LORE observations. Theoretical scattering from structured ionization events (e.g., sprites columns and gigantic jets) is not considered in this work.
Preearthquake anomalous ionospheric signatures observed at low‐mid latitude Indian station, Delhi, during the year 2015 to early 2016: Preliminary results

Published: July 2017

We have analyzed five major earthquake events measuring greater than 6 on Richter scale (M > 6) that occurred during the year 2015 to early 2016, affecting Indian region ionosphere, using F2 layer critical parameters (foF2, hmF2) obtained using Digisonde from a low‐mid latitude Indian station, Delhi (28.6°N, 77.2°E, 19.2°N geomagnetic latitude, 42.4°N dip). Normal day‐to‐day variability occurring in ionosphere is segregated by calculating F2 layer critical frequency and peak height variations (ΔfoF2, ΔhmF2) from the normal quiet time behavior apart from computing interquartile range. We find that the ionospheric F2 region across Delhi by and large shows some significant perturbations 3–4 days prior to these earthquake events, resulting in a large peak electron density variation of ~200%. These observed perturbations indicate towards a possibility of seismo‐ionospheric coupling as the solar and geomagnetic indices were normally quiet and stable during the period of these events. It was also observed that the precursory effect of earthquake was predominantly seen even outside the earthquake preparation zone, as given by Dobrovolsky et al. (1979). The thermosphere neutral composition (O/N2) as observed by Global Ultraviolet Imager, across Delhi, during these earthquake events does not show any marked variation. Further, the effect of earthquake events on ionospheric peak electron density is compared to the lower atmosphere meteorological phenomenon of 2015 sudden stratospheric warming event.
Pyroclastic flow deposits on Venus as indicators of renewed magmatic activity

Radar bright deposits on Venus that have diffuse margins suggest eruptions that distribute debris over large areas due to ground‐hugging flows from plume collapse. We examine deposits in eastern Eistla, western Eistla, Phoebe, and Dione Regiones using Magellan data and Earth‐based radar maps. The radar bright units have no marginal lobes or other features consistent with viscous flow. Their morphology, radar echo strength, polarization properties, and microwave emissivity are consistent with mantling deposits composed of few centimeters or larger clasts. This debris traveled downhill up to ~100 km on modest slopes and blanketed lava flows and tectonic features to depths of tens of centimeters to a few meters over areas up to 40 × 103 km2. There is evidence for ongoing removal and exhumation of previously buried terrain. A newly identified occurrence is associated with a ridge belt south of Ushas Mons. We also note radar bright streaks of coarse material west of Rona Chasma that reflect the last traces of a deposit mobilized by winds from the formation of Mirabeau crater. If the radar bright units originate by the collapse of eruption columns, with coarse fragmental material entrained and fluidized by hot gases, then their extent suggests large erupted volatile (CO2 or H2O) amounts. We propose that these deposits reflect the early stage of renewed magmatic activity, with volatile‐rich, disrupted magma escaping through vents in fractured regions of the upper crust. Rapidly eroding under Venus surface conditions or buried by subsequent eruptions, these markers of recently renewed activity have disappeared from older regions.
