Sufficient conditions of stochastic dominance for general transformations and its application in option strategy
Authors: Gao Jianwei , Zhao Feng , Gu Yundong 
Published: January 2018

Abstract
A counterexample is presented to show that the sufficient condition for one transformation dominating another by the second degree stochastic dominance, proposed by Theorem 5 of Levy (Stochastic dominance and expected utility: Survey and analysis, 1992), does not hold. Then, by restricting the monotone property of the dominating transformation, a revised exact sufficient condition for one transformation dominating another is given. Next, the stochastic dominance criteria, proposed by Meyer (Stochastic dominance and transformations of random variables, 1989) and developed by Levy (1992), are extended to the most general transformations. Moreover, such criteria are further generalized to transformations on discrete random variables. Finally, the authors employ this method to analyze the transformations resulting from holding a stock with the corresponding call option.

Abstract. We investigated the concentrations and vertical profiles of ozone over a 20-year period (1996–2016) at the SMEAR II station in southern Finland. Our results showed that the typical daily median ozone concentrations were in the range of 20–50 ppb with clear diurnal and annual patterns. In general, the profile of ozone concentrations illustrated an increase as a function of heights. The main aim of our study was to address the frequency and strength of ozone depletion events at this boreal forest site. We observed more than a thousand of 10 min periods at 4.2 m, with ozone concentrations below 10 ppb, and a few tens of cases with ozone concentrations below 2 ppb. Among these observations, a number of ozone depletion events that lasted for more than 3 h were identified, and they occurred mainly in autumn and winter months. The low ozone concentrations were likely related to the formation of a low mixing layer under the conditions of low temperatures, low wind speeds, high relative humidities and limited intensity of solar radiation.

Abstract. Located in a mountainous area of south-eastern Brazil, the municipality of Campos do Jordão has been hit by several landslides in recent history. Among those events, the landslides of early 2000 were significant in terms of the number of deaths (10), the population affected and the destruction of infrastructure that was caused. The purpose of this study is to assess the relative contribution of natural and human factors to triggering the landslides of the 2000 event. To achieve this goal, a detailed geotechnical survey was conducted in three representative slopes of the area to obtain geotechnical parameters needed for slope stability analysis. Then, a set of numerical experiments with GEO-SLOPE software was designed, including separate natural and anthropic factors. Results showed that natural factors, that is, high-intensity rainfall and geotechnical conditions, were not severe enough to trigger landslides in the study area and that human disturbance was entirely responsible for the landslide events of 2000. Since the anthropic effects used in the simulations are typical of hazardous urban areas in Brazil, we concluded that the implementation of public policies that constrain the occupation of landslide susceptible areas are urgently needed.

Published: January 2018

A adubação com boro geralmente é aplicada sem orientação adequada, usando sempre a filosofia de segurança, podendo acarretar problemas de nutrição nas plantas. O objetivo do trabalho foi avaliar os efeitos da aplicação de boro e capacidade de retenção de água no solo, nos componentes de produção, na produtividade e no acúmulo de boro na soja. Realizou-se um experimento em Ipameri-Go no ano agrícola de 2015/2016. O delineamento foi inteiramente casualizados (DIC) no esquema fatorial 3 x 5, sendo o primeiro fator disponibilidade de água (50; 70 e 90% da capacidade máxima de retenção de água no solo - CRA), e o segundo as doses de boro (0; 0,5; 1,0; 1,5 e 2,0 mg dm-3), com 4 repetições, em vasos de 5 dm3 de solo. Foram analisados o número de vagens/planta, número de grãos/vagem, massa seca da parte aérea e raiz, acúmulo de boro na parte aérea, raiz e acúmulo total de boro, a massa seca de 100 grãos e a produtividade por planta. Os resultados foram submetidos à análise de variância e de regressão. Verificou-se interação entre doses de boro e CRA. Com a CRA de 50% as plantas não respondem a adubação boratada. Com a disponibilidade de água de70% da CRA, o acúmulo de boro é crescente com as doses, mas a massa seca de raiz e de parte aérea, o número de vagens por planta e a produtividade de grãos aumentam até as doses de 0,7 a 1,0 mg dm-3. Quando a disponibilidade de água no solo é alta (CRA 90%), a massa seca de parte aérea e raiz, o acúmulo de boro na planta e número de vagens por planta aumentam até a dose máxima testada, de 2,0 mg dm-3.

Arte e afrobrasilidade como expoentes de luta e resistência
Authors: Alves Sirlene Ribeiro , Rodrigues Marcelino Euzébio 
Published: January 2018

O texto dialoga com a produção cultural das artes visuais de artistas afro- brasileiros em quatro expoentes significativos para arte brasileira: o Barroco, período onde negros e seus descendentes criaram singularidades e especificidades no campo das artes; a Academia Imperial de Belas Artes, que mesmo sendo um ambiente eurocentrado integrou alguns artistas negros significativos e transgressores da ordem hegemônica; a Modernidade brasileira, momento de transformação na representação da população negra e a Contemporaneidade, onde as questões raciais assumem novos contornos políticos e afirmam posicionamentos militantes. Ancorados nos estudos de CONDURU (2007, 2013), BAZIN (1993), DOSSIN (2000) pretendemos evidenciar o trabalho de artistas negros, produzidos não só por oposição ao branco, mas, também, pela negociação, pelo conflito e pelo diálogo com as forças da hegemonia branca. Essas potencias artísticas são em primeira instancia, as primeiras lutas por representatividade no campo das artes visuais no Brasil. Enviado em: 29 de maio de 2017.Aprovado em: 16 de junho de 2017.

Práticas musicais do cotidiano na Iniciação científica: diários de pesquisa em ambientes religiosos cristãos
Authors: Louro Ana Lúcia , Reck André 
Published: January 2018

Nesta comunicação relatamos uma pesquisa de Iniciação Científica, a partir da perspectiva da valorização dos conhecimentos cotidianos na formação de professores de música. Duas licenciandas e um bacharelando em música de cursos de uma universidade do sul do Brasil escreveram diários de pesquisa sobre sua atuação enquanto lideres de grupos musicais em igrejas Evangélicas e um ministério de música Católico, que foram analisados à luz de Zabalza (2004). Tomado o dilema principal: “Ser músico ou ministro de louvor”, surgiram duas categorias, considerando-se os horizontes de significado (Souza, 2013) dos alunos e dos músicos estudados por eles: 1. Amar a Deus mais do que a música; 2. Amar o próximo mais do que a música. A partir das leituras aqui propostas, pretende-se contribuir para os debates sobre pesquisa (auto)biográfica, especialmente com diários de pesquisa, estudos sobre ambientes religiosos cristão e formação de professores, a partir da reflexão sobre vivências significativas em suas vidas.

Formononetin inhibits lipopolysaccharide-induced release of high mobility group box 1 by upregulating SIRT1 in a PPARδ-dependent manner
Authors: Hwang Jung Seok , Kang Eun Sil , Han Sung Gu , Lim Dae-Seog , Paek Kyung Shin , Lee Chi-Ho , Seo Han Geuk 
Published: January 2018

Background
The release of high mobility group box 1 (HMGB1) induced by inflammatory signals acts as a cellular alarmin to trigger a chain of inflammatory responses. Although the inflammatory actions of HMGB1 are well studied, less is known about the therapeutic agents that can impede its release. This study investigated whether the isoflavonoid formononetin can modulate HMGB1 release in cellular inflammatory responses.

Methods
RAW264.7 murine macrophages were exposed to lipopolysaccharide (LPS) in the presence or absence of formononetin. The levels of HMGB1 release, sirtuin 1 (SIRT1) expression, and HMGB1 acetylation were analyzed by immunoblotting and real-time polymerase chain reaction. The effects of resveratrol and sirtinol, an activator and inhibitor of SIRT1, respectively, on LPS-induced HMGB1 release were also evaluated.

Results
Formononetin modulated cellular inflammatory responses by suppressing the release of HMGB1 by macrophages exposed to LPS. In RAW264.7 cells, formononetin significantly attenuated LPS-induced release of HMGB1 into the extracellular environment, which was accompanied by a reduction in its translocation from the nucleus to the cytoplasm. In addition, formononetin significantly induced mRNA and protein expression of SIRT1 in a peroxisome proliferator-activated receptor δ (PPARδ)-dependent manner. These effects of formononetin were dramatically attenuated in cells treated with small interfering RNA (siRNA) against PPARδ or with GSK0660, a specific inhibitor of PPARδ, indicating that PPARδ is involved in formononetin-mediated SIRT1 expression. In line with these effects, formononetin-mediated inhibition of HMGB1 release in LPS-treated cells was reversed by treatment with SIRT1-targeting siRNA or sirtinol, a SIRT1 inhibitor. By contrast, resveratrol, a SIRT1 activator, further potentiated the inhibitory effect of formononetin on LPS-induced HMGB1 release, revealing a possible mechanism by which formononetin regulates HMGB1 release through SIRT1. Furthermore, modulation of SIRT1 expression by transfection of SIRT1- or PPARδ-targeting siRNA significantly counteracted the inhibitory effects of formononetin on LPS-induced HMGB1 acetylation, which was responsible for HMGB1 release.

Discussion
This study shows for the first time that formononetin inhibits HMGB1 release by decreasing HMGB1 acetylation via upregulating SIRT1 in a PPARδ-dependent manner. Formononetin consequently exhibits anti-inflammatory activity. Identification of agents, such as formononetin, which can block HMGB1 release, may help to treat inflammation-related disorders.
Statistics of Extreme Time‐Integrated Geomagnetic Activity

Published: January 2018

AbstractA statistical analysis of the time‐integrated Dst index is performed over 1958–2007. The tail of the probability distribution of extreme time‐integrated Dst events, which occur during strong geomagnetic storms, can be precisely fitted by a power law function with upper cutoff, apparently not exceeded even by the 1859 Carrington event. This time‐integrated Dst is expected to be a reasonable proxy for maximum densities of MeV electrons in the heart of the outer radiation belt, which are known to pose a serious threat to satellites. During such strong events, a correlation is found between the time‐integrated levels of various physical quantities, such as interplanetary magnetic field Bz, particle energy fluxes measured during injections in the magnetotail, geosynchronous ULF wave index, and geomagnetic activity in the inner magnetosphere, suggesting cumulative effects from successive disturbances.

AbstractThe effect of the plasmapause on equatorially radially propagating fast magnetosonic (MS) waves in the Earth's dipole magnetic field is studied by using finite difference time domain method. We run 1‐D simulation for three different density profiles: (1) no plasmapause, (2) with a plasmapause, and (3) with a plasmapause accompanied with fine‐scale density irregularity. We find that (1) without plasmapause the radially inward propagating MS wave can reach ionosphere and continuously propagate to lower altitude if no damping mechanism is considered. The wave properties follow the cold plasma dispersion relation locally along its trajectory. (2) For simulation with a plasmapause with a scale length of 0.006 RE compared to wavelength, only a small fraction of the MS wave power is reflected by the plasmapause. WKB approximation is generally valid for such plasmapause. (3) The multiple fine‐scale density irregularities near the outer edge of plasmapause can effectively block the MS wave propagation, resulting in a terminating boundary for MS waves near the plasmapause.

AbstractThe Electron Spectrometer (ELS) of the Cassini Plasma Spectrometer has observed photoelectrons produced in the plume of Enceladus. These photoelectrons are observed during Enceladus encounters in the energetic particle shadow where the spacecraft is largely shielded from penetrating radiation by the moon. We present a complex electron spectrum at Enceladus including evidence of two previously unidentified electron populations at 6–10 eV and 10–16 eV. We estimate that the proportion of “hot” (>15 eV) to “cold” (<15 eV) electrons during the Enceladus flybys is ≈ 0.1–0.5%. We have constructed a model of photoelectron production in the plume and compared it with ELS Enceladus flyby data by scaling and energy shifting according to spacecraft potential. We suggest that the complex structure of the electron spectrum observed can be explained entirely by photoelectron production in the plume ionosphere.

Published: January 2018

AbstractAn analysis of the atmospheric branch of the hydrological cycle by means of a 15 km resolution numerical integration performed using Weather Research and Forecasting (WRF) nested in ERA Interim is presented. Two WRF experiments covering the period 2010–2014 were prepared. The first one (N) was configured as in standard numerical downscaling experiments. The second one (D), with the same parameterizations, included a step of 3DVAR data assimilation every 6 h. Apart from comparing our results with ERA Interim data, several observational data sets were used to validate the precipitable water (radiosondes and MODIS data), precipitation (EOBS, ECA&D, TRMM, and GPCP), or evaporation (GLEAM). The verification results showed that the D experiment systematically performs better than N and in many instances, too, better than the forcing reanalysis. According to the results, the leading terms of the water balance are the tendency of the precipitable water, the divergence of moisture flux, evaporation, and precipitation. No spatial patterns were recognizable for the annual accumulated evaporation, but the effect of the Atlantic fronts was detected in the precipitation patterns. The transboundary moisture fluxes through the contour of the Iberian Peninsula behave differently depending on the season during 2010–2014. During winter, they show a net moisture import through the boundaries. During spring, summer, or autumn moisture is exported specially through the Mediterranean coast, and only during midday, this feature is reversed due to sea breezes.

AbstractControlling movements of electrons and holes is the key task in developing today's highly sophisticated information society. As transistors reach their physical limits, the semiconductor industry is seeking the next alternative to sustain its economy and to unfold a new era of human civilization. In this context, a completely new information token, i.e., ions instead of electrons, is promising. The current trend in solid‐state nanoionics for applications in energy storage, sensing, and brain‐type information processing, requires the ability to control the properties of matter at the ultimate atomic scale. Here, a conceptually novel nanoarchitectonic strategy is proposed for controlling the number of dopant atoms in a solid electrolyte to obtain discrete electrical properties. Using α‐Ag2+δS nanodots with a finite number of nonstoichiometry excess dopants as a model system, a theory matched with experiments is presented that reveals the role of physical parameters, namely, the separation between electrochemical energy levels and the cohesive energy, underlying atomic‐scale manipulation of dopants in nanodots. This strategy can be applied to different nanoscale materials as their properties strongly depend on the number of doping atoms/ions, and has the potential to create a new paradigm based on controlled single atom/ion transfer.
