Preparing for the new age of the Nagoya Protocol in scientific ocean drilling
Authors: Xiao Nan , Ahagon Naokazu , Kubo Yusuke , Morioka Hajimu
Published: October 2018

Abstract. Deep biosphere research has become one of the major scientific focuses in
ocean drilling science. Increased scientific attention to microbiological
research of the subseafloor environment raises the complications and concerns
related to adherence to the Nagoya Protocol of the Convention on Biological
Diversity (CBD). The Nagoya Protocol's implementation has prompted new
legislation that could change international collaborative research on the
geomicrobiology of the subseafloor. In this paper, we summarize the central
points of the Nagoya Protocol on access and benefit-sharing (ABS) and
discuss their relationship to ocean drilling research. In addition, we
addressed the challenges faced by ocean drilling in complying with this
international convention.
Crustal Density Model of the Sea of Marmara: Geophysical Data Integration and 3D Gravity Modelling
Authors: Gholamrezaie Ershad , Scheck-Wenderoth Magdalena , Sippel Judith , Heidbach Oliver , Strecker Manfred R.
Published: October 2018

Abstract. The Sea of Marmara, in Northwest Turkey, is a transition zone where the dextral North Anatolian Fault Zone (NAFZ) propagates westward from the Anatolian plate to the Aegean plate. The area is of interest in the context of seismic hazard in the vicinity of Istanbul, a metropolitan area with about 15 million inhabitants. Geophysical observations indicate that the crust is heterogeneous beneath the Marmara Basin, but a detailed characterization of the crustal heterogeneities is still missing. To assess if and how crustal heterogeneities are related to the NAFZ segmentation below the Marmara Sea, we develop a new crustal-scale 3D density model which integrates geological and seismological data and is additionally constrained by 3D gravity modelling. This model indicates that the observed gravitational anomalies originate from significant density heterogeneities within the crust. Two layers of sediments, one syn-kinematic and one pre-kinematic with respect to the Marmara Sea formation are underlain by a heterogeneous crystalline crust. A felsic upper crystalline crust (average density of 2720 kg m−3) and an intermediate to mafic lower crystalline crust (average density of 2890 kg m−3) appear to be crosscut by two large, dome-shaped mafic high-density bodies (average density of 3050 kg m−3) of considerable thickness above a rather uniform lithospheric mantle (3300 kg m−3). The spatial correlation between the bent segments of the fault and the location of the high-density bodies suggests that the distribution of lithological heterogeneities within the crust controls the rheological behaviour along the NAFZ, and consequently, influences fault segmentation and propagation dynamics.
Dynamic Ocean Topography of the Greenland Sea: A comparison between satellite altimetry and ocean modeling
Authors: Müller Felix L. , Wekerle Claudia , Dettmering Denise , Passaro Marcello , Bosch Wolfgang , Seitz Florian
Published: October 2018

Abstract. The dynamic ocean topography (DOT) in the polar seas can be described by satellite altimetry sea surface height observations combined with geoid information and by ocean models. The altimetry observations are characterized by an irregular sampling and seasonal sea-ice coverage complicating reliable DOT estimations. Models display various spatio-temporal resolutions, but are limited to their computational and mathematical context and introduced forcing models. In the present paper, ALES+ retracked altimetry ranges and derived along-track DOT heights of ESA's Envisat and water heights of the Finite Element Sea-ice Ocean Model (FESOM) are compared to investigate similarities and discrepancies. The study period covers the years 2003–2009. An assessment analysis regarding seasonal DOT variabilities shows good accordance and confirms the most dominant impact of the annual signal in both datasets. A comparison based on estimated regional annual signal components shows 2–3 times stronger amplitudes of the observations but good agreement of the phase. Reducing both datasets by constant offsets and the annual signal reveals small regional residuals and highly correlated DOT time series (correlation coefficient at least 0.67). The highest correlations can be found in areas that are ice-free and affected by ocean currents. However, differences are visible in sea-ice covered shelf regions. Furthermore, remaining constant artificial elevations in the observational data can be addressed to an insufficient representation of the used geoid. In general, the comparison results in good accordance between simulated and altimetry based description of the DOT in the Greenland Sea. Furthermore, the investigation shows that combining both datasets and exploiting the advantages of along-track altimetry observations and those of homogeneous modeled DOT representations leads to a deeper comprehension of the Arctic Ocean's DOT.

La televisión informativa en el entorno digital: análisis de las ediciones diarias de las cadenas generalistas líderes de audiencia en España
Authors: Gómez Rubio Leire , López Vidales Nereida , Vicente Torrico David
Published: October 2018

Aunque en un principio cabe pensar que todos los informativos de la televisión generalista en el ámbito nacional se parecen, un análisis pormenorizado de ellos pone en evidencia que presentan notables diferencias entre sí, tanto en estructura, como en contenidos, presentación y puesta en escena. En las siguientes páginas, se exponen los resultados de un estudio en el que se han analizado y comparado los informativos diarios de las cadenas líderes de audiencia en el Estado: Telecinco, TVE y Antena 3. Entre los principales resultados alcanzados, nos encontramos con que, a pesar de que actualmente conviven diferentes perfiles informativos, los más seguidos por la audiencia son aquellos que priman los aspectos espectaculares y emotivos de las noticias por encima de la información estricta de los hechos.

La imagen negativa de la inmigración en los medios: ¿cuestión de estrategia?
Authors: Ruiz-Aranguren María , Cantalapiedra González María José
Published: October 2018

Este trabajo de investigación parte de la hipótesis de que los medios de comunicación generalistas no cuentan con una estrategia para informar sobre inmigración. La literatura reciente ha mostrado a través de diferentes metodologías que los periodistas asocian valores negativos a las personas inmigrantes en sus informaciones, contribuyendo a su criminalización. Esta investigación propone una nueva metodología que se inserta en la tradición del Newsmaking. De esta manera, presenta un cambio en el foco de análisis, desde el producto informativo hasta el proceso de generación de informaciones, esto es, las rutinas productivas y la interacción de los periodistas con las fuentes. En el estudio de caso que presentamos, centrado en los principales medios de comunicación vascos, se concluye que efectivamente los periodistas no cuentan con pautas específicas y, por tanto, más allá de sus posturas ideológicas, improvisan al informar sobre esta cuestión.
Periodistas infiltrados en las redes sociales. Estudio de caso: Anna Erelle, en las entrañas del terrorismo virtual
Authors: López Hidalgo Antonio , Fernández Barrero María Ángeles
Published: October 2018

El auge de Internet en las dos últimas décadas ha tenido su impacto en el ejercicio de la profesión periodística. En lo que respecta al periodismo de investigación, las redes sociales han comenzado a proporcionar un nuevo escenario para la infiltración con fines informativos, tanto las inmersiones parciales, que favorecen la toma de contacto del periodista con grupos de riesgo, como las infiltraciones desarrolladas de manera íntegra en la red. El caso más sintomático ha sido el de la periodista francesa Anna Erelle, que recurrió a la infiltración con un perfil falso en las redes sociales para contactar con terroristas radicales islámicos. Su experiencia de inmersión se desarrolla completamente en línea y consigue hacer creer al yihadista Abu Bilel que se iba a casar con él para extraer información sobre IS y la captación de jóvenes para la yihad en las redes. A Erelle le asaltaron las dudas éticas sobre el método utilizado pero la fragrante actividad delictiva del grupo disipó sus planteamientos. El debate ético que siempre ha acompañado a la infiltración como método de investigación periodística se intensifica en las redes, por su facilidad de acceso, más versátil de la red, y su estructura descentralizada.
Estéticas de la civilidad. El “buen gusto” en la prensa porteña de 1801 – 1827
Authors: Maggio-Ramírez Matías , Guillamón Guillermina
Published: October 2018

El objetivo de las líneas que siguen reside en analizar el potencial del concepto de “buen gusto” en la prensa porteña entre 1801 y 1827 para indagar las diversas facetas de la sociabilidad y sensibilidad de la élite letrada. Específicamente, se buscó el corrimiento del “buen gusto” desde las acepciones ligadas al espectro de la civilidad, en tanto buenas maneras y costumbres, hasta referirse a los juicios estéticos propios del teatro y la música. La hipótesis que guía el trabajo es, pues, que el concepto atravesó por un doble proceso de cambio: uno, relacionado a la escala y otro a su carga semántica. Sin embargo, más allá de ello, el concepto siempre refirió a la identidad como frontera oposicional que permitió a la élite constituirse al tiempo que legitimarse.

Actions Speak Louder than Words: Stop Talking-Do! The Role of Social Psychology to turn Talkers into Doers to Nourish Organizational Behavior
Authors: Fisher Eddie John , González Yorkys Santana , Fisher Eddie
Published: October 2018

Effective and capable people are in high demand amongst businesses and educational establishments. Companies are not getting the best out of their people. It appears that there is a gap between what people are saying they are going to do and what they actually do. This research, based on a combination of what is already known about the subject matter under investigation and the practical experiences of research participants, investigated how this organizational behavior gap could be closed and what the potential benefits would be for both individuals and companies. The main focus of this research was to identify effective solutions how talkers could become doers and how talkers would benefit from adopting and applying the suggested recommendations how changes in attitude/behaviors and routines could lead to improved action-based capabilities. The outcome of this research suggests that the contributions made by this research can be measured through appropriate Key Performance Indicators (KPIs) to measure and demonstrate the effectiveness of considered performance improvements. It is suggested that the contributions from this research can be applied universally provided that cultural diversity is taken into consideration.

Anastacio Aquino : icono histórico de los Nonualcos.
Authors: Ramírez Fuentes José Alfredo
Published: October 2018

Dentro de la historia salvadoreña varios grandes personajes son recordados, pero solamente un indígena ha sido capaz de permanecer en la tradición, los estudios históricos y la identidad de una región completa. Actualmente Anastacio Aquino y el movimiento que lideró son ejemplo de lucha y reivindicaciones sociales.Este estudio se propone arrojar luz sobre algunos aspectos desconocidos del movimiento de Aquino y la época en la que vivió. Los eventos de su vida están marcados por la tradición y no por la investigación histórica con fuentes primarias, este artículo propone solventar en parte esa carencia. Junto a esa intención, se busca también colocar a Aquino en su contexto histórico, pasando de ser un indígena miembro de su comunidad nonualca hasta convertirse en un ciudadano salvadoreño que trata de proteger a su comunidad, que es lo que conoce, y no al Estado salvadoreño en formación que está a su vez subordinado al Estado federal centroamericano.Revista de Humanidades y Ciencias Sociales, n° 8, julio-diciembre 2016: 87-122
Las Matemáticas en sus relaciones con la prosperidad de los Estados.
Authors: Del Valle José Cecilio
Published: October 2018

El discurso Las matemáticas en sus relaciones con la prosperidad de los Estados fue pronunciado por del Valle en la Ciudad de Guatemala el 16 de mayo de 1831 en ocasión de inaugurarse un curso de matemáticas. Este es sin duda uno de los escritos más importantes de este célebre sabio centroamericano. Es un escrito representativo del pensamiento ilustrado centroamericano que busca el progreso individual y social basado en la razón, bajo la convicción de que la humanidad se dirige a niveles desconocidos de progreso y perfeccionamiento a partir del conocimiento del hombre, la sociedad y la naturaleza. Todo esto por medio del desarrollo de las ciencias naturales, sociales y humanas en las cuales la matemática es fundamental.Afirma Valle “No hay ciencias inútiles. Todas hacen bienes grandes al género humano. Pero las matemáticas son las que ayudan a producirlas”. Este discurso trata precisamente del impacto de las matemáticas en todos los ámbitos de la vida. Entrenan al ser humano a pensar con exactitud, son la herramienta fundamental para conocer la naturaleza; desarrollar la ciencia de la riqueza; calcular los bienes y los males en las decisiones políticas; calcular el bien de los pueblos en materia de legislación; calcular la utilidad o el dolor en las decisiones morales; desarrollar las artes militares y evitar derramamientos de sangre innecesarios; asegurar la libertad de los pueblos. Al desarrollo de las matemáticas también se les puede atribuir una inﬂuencia enorme para que la filosofía y las humanidades discurrieran con rigor. Este maravilloso escrito da lecciones sobre la importancia de las matemáticas en el desarrollo de los pueblos, más allá de las ciencias naturales donde estamos acostumbrados a pensar en su utilidad. Por ello constituye una estrategia de desarrollo muy vigente en la actualidad.Revista de Humanidades y Ciencias Sociales, n° 8, julio-diciembre 2016: 173-186
Violencia y seguridad : dos claves para resignificar la paz en El Salvador.
Authors: Pearce Jenny
Published: October 2018

Este documento explora las herramientas conceptuales para invertir significados en la palabra “paz” para alentar un debate más amplio y profundo sobre los significados del Acuerdo de 1992 a la luz de las violencias de la posguerra. La paz corre el peligro de ser un “significante vacío” si no está invertido en significados filosóficos y prácticos para la sociedad que lo invoca. El documento argumenta que el primer paso es ver la “paz” como lo opuesto a la violencia, no la guerra o el conﬂicto. Argumenta que la violencia es un fenómeno cargado de significados y que genera significados. Todas las violencias importan. No deberíamos seleccionar algunos como más importantes que otros. La seguridad debe vincularse a las prácticas que reducen la violencia. Debería abrir el espacio para que las personas construyan condiciones para vivir juntas sin violencia.Revista de Humanidades y Ciencias Sociales, n° 9, enero-junio 2017: 27-54
O PADRÃO DE CHUVAS NA REGIÃO DO ABC PAULISTA: OS EXTREMOS E SEUS IMPACTOS
Authors: Valverde María Cleofé , Cardoso Andréa De Oliveira , Brambila Ricardo
Published: October 2018

Este trabalho analisou o padrão de chuvas e seus extremos na região do ABC Paulista, localizada no setor sudeste da Região Metropolitana de São Paulo englobando os municípios de Santo André, São Bernardo do Campo, São Caetano do Sul, Mauá, Diadema, Ribeirão Pires e Rio Grande da Serra. Também, avaliaram-se os impactos das chuvas intensas, através da frequência de eventos de deslizamentos de terra, inundações e alagamentos. O resultado da climatologia (1968-1998) identificou os meses de janeiro e fevereiro como os mais chuvosos da região, sendo Ribeirão Pires e Mauá os municípios com maiores acumulados de chuva no verão. A comparação da climatologia com a média das chuvas de um período mais atual (1999-2014) mostrou um incremento no mês de janeiro em Diadema, São Caetano do Sul, São Bernardo do Campo e Santo André, acompanhado, em contrapartida, pela redução das chuvas anuais. Os impactos das chuvas intensas foram verificados na análise da variabilidade de índices climáticos de chuva, a qual acompanhou a frequência anual dos eventos de deslizamentos e inundações, identificando os anos de 2010 e 2011 como aqueles de maiores chuvas e consequentemente com a maior ocorrência de desastres. Os eventos de deslizamentos são mais frequentes no verão, com destaque para os municípios de Ribeirão Pires, Mauá e Santo André. Também, se identificaram tendências positivas no número de dias com chuvas ≥ 50 mm (R50mm) em todos os municípios, sendo este limiar de intensidade um deflagrador de eventos de deslizamentos e inundações em áreas mais susceptíveis. Finalmente verificaram-se locais no ABC Paulista que se caracterizaram por apresentar baixas (região leste de Mauá) e altas (Diadema) intensidades de chuva, independentemente do verão ser muito chuvoso (2010) ou seco (2014). Nestas mesmas condições de anos extremos, Santo André apresentou a mais alta frequência de deslizamentos e inundações, sem a caraterística de apresentar as maiores intensidades de chuvas.

Este estudo visa à caracterização das condições predominantes de direção e velocidade do vento sobre a região marinha adjacente à costa do Espírito Santo, bem como a construção de cenários típicos de vento para esta região sob a ação da Alta Subtropical do Atlântico Sul, dos Sistemas Transientes e da Zona de Convergência do Atlântico Sul. Os resultados mostraram que sob a atuação da Alta Subtropical do Atlântico Sul, ventos de norte (nordeste e leste) foram mais frequentes nas regiões mais próxima (distante da) da costa e no sul (norte) da área de estudo.  Sob a atuação de Sistemas Transientes, as maiores frequências foram encontradas no setor central para ventos de sul, no setor norte para ventos de sudeste, e no setor sul para ventos de sudoeste. Durante a atuação da ZCAS, ventos de sul, sudeste e sudoeste foram predominantes, enquanto ventos de norte, nordeste e leste foram dominantes nos períodos pré-ZCAS e pós-ZCAS. Os achados deste estudo irão contribuir para o melhor entendimento da interação oceano-atmosfera na região marinha adjacente à costa do Espírito Santo.
IMPACTOS DAS ONDAS DE FRIO SOBRE A SAÚDE PÚBLICA NO MUNICÍPIO DE SÃO JOAQUIM - SANTA CATARINA - BRASIL
Authors: Silveira Rafael Brito , Mendonça Magaly , Franke Alberto Elvino , Bitencourt Daniel Pires
Published: October 2018

Para várias partes do mundo têm sido conduzidos estudos que tratam dos impactos dos extremos de temperatura sobre a saúde pública. Neste trabalho é apresentada uma análise da ocorrência de ondas de frio (OdF), assim como os impactos destes eventos no número de internações hospitalares do município de São Joaquim, Santa Catarina (SC), Brasil. Por meio de avaliações estatísticas, foram comparados dados de temperatura média do ar e de número de dias com OdF com dados de internações por doenças respiratórias e circulatórias. Observou-se que São Joaquim é um município com significativa ocorrência de OdF, com média de 3,5 OdF/ano. Durante os eventos, as temperaturas são em geral rigorosamente baixas, principalmente no inverno austral. Os resultados comparativos apontam com mais clareza impactos do frio sobre as internações hospitalares devido à pneumonia. O frio no município de São Joaquim explica 39 % da morbidade por pneumonia. Também foram encontrados indícios de que os maiores impactos na saúde pública local sejam causados por invernos que apresentem número maior de dias frios no decorrer da estação, mesmo que o frio não seja tão rigoroso.

Re-examining Higher Education Internationalization in Taiwan: University Strategies for Implementing Overseas Programmes
Authors: Liao Yuching
Published: October 2018

This study clarifies the rationale for offering overseas programmes as an internationalization strategy by Taiwanese higher education institutions through an analysis of related university documents and interview data. In doing so, this study highlights how institutional goals and characteristics, as well as social and cultural backgrounds, affect the internationalization of higher education based on the following two points. First, in addition to the pursuit of academic excellence and expanding student markets, university strategies are based on its particular history, resources, development goals, and orientation. Second, although different strategies were observed among the examined universities, the Chinese element and the pluralistic value of Taiwanese society have influenced the overseas programmes offered by Taiwanese universities. This paper argues that instead of merely adopting the international standard or pursuing academic excellence, it is essential for Taiwanese universities to implement internationalization strategies in order to determine their meaning and purpose in the context of Taiwanese higher education.

This analysis investigates the determinants of the capital structure of the SMEs belonging in the so-called Italian Mezzogiorno, that is perfectly integrated but slowly growing area the South of the country, with respect to the capital structure of the SMEs of the more developed Italian regions. The study is based on a large sample of Italian manufacturing SMEs covering the 2001-2013 years and she is carried through fixed effect panel estimations of several standard leverage models. The empirical findings show that there are structural differences in the working of regional model reaffirming some distinctive features of the financial behaviour of the SMEs belonging in the Southern Italian regions.
Property Rights, Tax Avoidance and Capital Structure: Data from China Stock Markets
Authors: Wang Pei , Guo Kun , Ding Dan , Li Shuyi
Published: October 2018

This paper investigates the influence of tax avoidance on capital structure based on share ownership under China’s economic system. Previous research has indicated that tax avoidance exits and has a potential effect on firms’ capital structure, but there is little literature focusing on this influence based on China’s economic system. In light of that, this paper uses A-share data of the Shanghai and Shenzhen stock exchange from 2007 to 2016 as samples to study the impact of tax avoidance on the capital structure based on China’s economic system. The results suggest that, firstly, there is a significant negative correlation between tax avoidance and the debt ratio of the listed companies; secondly, there is a significant difference in the effect of corporate tax avoidance on the debt ratio of different industries and different equity ownership. Besides, by regrouping the samples according to the share ownership and the degree of tax avoidance, it is revealed that China’s unique economic system would lead to an impact of tax avoidance on the capital structure that differs from other countries. Finally, it is found that there is a negative correlation between the degree of tax avoidance of the listed companies and the dynamic adjustment of assets-liability ratio through the extended study, further verifying that there is a substitution relationship between tax avoidance of the listed companies and their debt financing.
Potentiometric detection of low-levels of sulfamethazine in milk and pharmaceutical formulations using novel plastic membrane sensors
Authors: Hassan Saad S. M. , Kamel Ayman H. , Elbehery Nada H. A.
Published: October 2018

Novel potentiometric sensors for selective screening of sulfamethazine (SMZ) in pharmaceutical preparations and milk samples are reported. The sensor membranes were made from PVC matrix doped with magnesium(II)-, manganese(II)- and dichlorotin (IV)-phthalocyanines as ionophores and aliquat-336 and nitron/SMZ ion-pair complex as ion exchangers. These sensors revealed fast, stable and near-Nernstian anionic response for the singly charged sulfamethazine anion over the concentration range 10-2 - 10-5 M. The sensors exhibited good selectivity towards SMZ over most known anions, excipients and diluents commonly added in drug preparations. Validation of the proposed methods was demonstrated via evaluating the detection limit, linear response range, accuracy, precision (within-day repeatability) and between-day-variability. The sensors are easily interfaced with a double channel flow injection system and used for continuous monitoring of SMZ in drug formulations, spiked milk samples and biological tissues. The method offers the advantages of design simplicity, results accuracy, and automation feasibility.
Application of Fe3O4@SiO2/GO nanocomposite for sensitive and selective electrochemical sensing of tryptophan
Authors: Beitollahi Hadi , Safaei Mohadeseh , Shishehbore Masoud Reza , Tajik Somayeh
Published: October 2018

A simple strategy for determination of tryptophan (TRP) based on Fe3O4@SiO2/GO nano­composite modified graphite screen printed electrode (Fe3O4@SiO2/GO/SPE) is re­ported. Cyclic voltammetry (CV) and differential pulse voltammetry (DPV) were used to characterize the performance of the sensor. The Fe3O4@SiO2/GO/SPE displayed excellent electro­che­mical catalytic activities. The oxidation overpotentials of tryptophan decreased significantly and its oxidation peak current increased dramatically at Fe3O4@SiO2/GO/SPE. Under the optimized experimental conditions tryptophan showed linear response over the range of 1.0-400.0 μM. The lower detection limit was found to be 0.2 μM for tryptophan. The prac­tical application of the modified electrode was demonstrated by measuring the concen­tration of tryptophan in real samples.
Capillary Electrophoresis with Laser Induced Fluorescence Detection for Study of the Association of HSP60 Gene Polymorphism with Gouty Arthritis
Authors: Ren Dongxia , Fan Min , Sun Chengjun , Zhou Chen , Li Yongxin
Published: October 2018

Background: Gout arthritis is a common inflammatory arthritis and it poses a major threat to human health. Objective: A method of capillary electrophoresis with laser-induced fluorescence detection (CE-LIF) for the detection of HSP60 gene polymorphism has been developed and applied to the exploration of correlation between gouty arthritis and HSP60 gene polymorphism. Methods: The genomic deoxyribonucleic acid from 59 patients with gouty arthritis and 64 control subjects was extracted and the conservative fragment of HSP60 was amplified. The products were digested with restriction endonuclease NlaIII and then separated and detected by the proposed method. Results: In the case group, there were 7 cases of TT genotype, 29 cases of CC genotype, and 23 cases of CT genotype. In the control group, there were 4 cases of TT genotype, 6 cases of CC genotype, and 54 cases of CT genotype. The detection results of the samples were statistically analyzed by binary logistic regression and Spearman correlation analysis. After adjusting gender, age, and other compounding factors, the TT genotype and CT genotype of the HSP60 gene were found to affect gouty arthritis.

A rapid assessment of the areal extent of landslide disasters is one of the main challenges facing by the scientific community. Satellite radar data represent a powerful tool for the rapid detection of landslides over large spatial scales, even in case of persistent cloud cover. To define landslide locations, radar data need to be firstly pre-processed and then elaborated for the extraction of the required information. Segmentation represents one of the most useful procedures for identifying land cover changes induced by landslides. In this study, we present an application of the i.segment module of GRASS GIS software for segmenting radar-derived data. As study area, we selected the Tagari River valley in Papua New Guinea, where massive landslides were triggered by a M7.5 earthquake on February 25, 2018. A comparison with ground truth data revealed a suitable performance of i.segment. Particular segmentation patterns, in fact, resulted in the areas affected by landslides with respect to the external ones, or to the same areas before the earthquake. These patterns highlighted a relevant contrast of radar backscattering values recorded before and after the landslides. With our procedure, we were able to define the extension of the mass movements that occurred in the study area, just three days after the M7.5 earthquake.

Background. Although pathogenic Gram-negative bacteria lack their own ubiquitination machinery, they have evolved or acquired virulence effectors that can manipulate the host ubiquitination process through structural and/or functional mimicry of host machinery. Many such effectors have been identified in a wide variety of bacterial pathogens that share little sequence similarity amongst themselves or with eukaryotic ubiquitin E3 ligases.

Methods. To allow identification of novel bacterial E3 ubiquitin ligase effectors from protein sequences we have developed a machine learning approach, the SVM-based Identification and Evaluation of Virulence Effector Ubiquitin ligases (SIEVE-Ub). We extend the string kernel approach used previously to sequence classification by introducing reduced amino acid (RAA) alphabet encoding for protein sequences.

Results. We found that 14mer peptides with amino acids represented as simply either hydrophobic or hydrophilic provided the best models for discrimination of E3 ligases from other effector proteins with a receiver-operator characteristic area under the curve (AUC) of 0.90. When considering a subset of E3 ubiquitin ligase effectors that do not fall into known sequence based families we found that the AUC was 0.82, demonstrating the effectiveness of our method at identifying novel functional family members. Recursive feature elimination was used to identify a parsimonious set of 100 RAA peptides that provided good discrimination, and these peptides were found to be located in functionally important regions of the proteins involved in E2 and host target protein binding.Our general approach enables construction of models based on other effector functions. We used SIEVE-Ub to predict seven potential novel E3 ligases from a large set of bacterial genomes. SIEVE-Ub is available for download at https://github.com/biodataganache/SIEVE-Ub

Setiap media promosi destinasi wisata memiliki kelebihan dan kekurangan, maka perubahan format media pun akan membawa konsekuensi. Pembahasan ini hendak melihat bagaimana performa brosur dan situs web tersebut dalam mempromosikan museum-museum rekanan sebagai destinasi wisata. Penelitian ini bersifat kualitatifdeskriptif menggunakan metode studi kasus instrumental dengan harapan kelak menjadi acuan bagi promosi destinasi wisata museum. Hasil penelitian menunjukkan bahwa kedua media memenuhi kriteria media promosi destinasi wisata yang ideal. Konten akurat (pada saat informasi dicantumkan) dalam menampilkan fasilitas museum-museum sebagai destinasi wisata.Tampilan kedua media atraktif. Agar semakin optimal diperlukan pesan yang lebih kuatuntuk memotivasi wisata ke museum, yang mampu memerangi biaya psikologis calon pengunjung.Situs web perlu penambahan elemen interaktif dan audio visual agar makin atraktif, serta menambah tautan dengan situs-situs lain (dengan peminatan serupa), direktori, portal, atau situs web komunitas tertentu. Akan lebih baik jika ditunjang dengan promosi media-media melalui lain yang mampu menjangkau khalayak luas dan sesuai dengan kemajuan teknologi, seperti melalui media jejaring sosial dan aplikasi mobile.
A Mechanical Model of Cellular Solids for Energy Absorption
Authors: Avalle Massimiliano , Belingardi Giovanni
Published: October 2018

Cellular materials, also known as foams, have a variety of applications in the field of packaging, and shock mitigation in the case of crash of vehicles, due to their ability to protect goods by absorbing energy in the case of impact while reducing the transmitted loads. To properly design energy absorption devices and systems such as bumpers, road barriers, helmets, sole paddings, packages, etc. it is necessary to use precisely predictive models of cellular materials, in order to select the most suitable foam for the considered application. The model must describe the stress–strain behavior, at least uniaxial compression, but also sometimes the tension and multiaxial loading, then energy absorption characteristics is evaluated. Moreover, it must take into account affecting factors like the strain‐rate. Secondarily, modeling the influence of the density heavily helps designer in selecting the best solution in terms of minimum weight per given energy to dissipate. In previous works, the authors present more than one model able to describe the quasi‐static stress–strain behavior of several cellular materials. The current paper presents a very general model able to describe, with properly identified parameters, the mechanical characteristics of a much larger variety of cellular materials including metal foams, foam mechanical properties (like, e.g., the dependence on density), and takes into account the influence of strain‐rate. Among the considered materials are the Foaminal® aluminum foam and the APM® hybrid foam. The model is fitted to experimental tests with parameters identified based on past experimental data from the authors themselves. Tests include quasi‐static, dynamic, and impact tests at different loading speed and impact energy. It is shown that the proposed model is fundamentally suitable for most materials, virtually any foamed material, and it is an outstandingly useful tool for designers in the mentioned areas.

A key challenge for optical circuits is the ability to integrate nonlinear optical signal processing components such as optical modulators and frequency mixers at the chip scale. Optical antennas that focus light into nanoscale volumes can be utilized to shrink the footprint and increase the efficiency of these components. Multiresonant antennas that enhance both optical absorption and emission process are recently demonstrated to enable efficient nonlinear frequency conversion at the nanoscale and are promising as structures for second harmonic generation (SHG) and upconversion. Here, the ability of colloidal metasurfaces fabricated by self‐assembly as on‐chip platforms for enhanced SHG is demonstrated. These metasurfaces exhibit high spatial overlap of multiple surface plasmon modes whose frequencies can be independently tuned through appropriate design of colloidal and metasurface geometries. It is demonstrated that these bottom‐up structures rival lithographic nonlinear optical antennas in SHG efficiency, suggesting the potential for these colloidal metasurfaces in integrated on‐chip architectures.

Black phosphorus (BP) has attracted great attentions in the last few years, but their applications in optoelectronics have been strongly hindered by the poor environmental stability, especially under light irradiation. Herein, the fabrication of surface passivated few‐layer BP assisted by polymer ionic liquids (PILs) is reported. The PIL‐modified 2D BP exhibits excellent stability under ambient conditions, with negligible deterioration in 100 d. Furthermore, the PILs attached on the BP surface provide reliable and flexible electrical contact between the few‐layer BP and other device components. As a proof of concept, PIL‐modified BP nanosheets are successfully applied in flexible photodetectors, which show high flexibility, good detectivity with no obvious performance deterioration in 120 h. This work demonstrates that the PIL modification can endow BP nanosheets with excellent environmental stability and good conductivity, so that may significantly expand the applications of BP in flexible optoelectronics.

Unevenly distributed dendrite growth is usually viewed as a consequence to the diffusion‐limited interface instability during electrodeposition, leading to one of the most serious obstacles hindering the application of high‐capacity lithium (Li) metal anodes. Herein, a fundamental issue of modifying Li plating behavior using a structure of 3D vertical graphene nanowalls on nickel (Ni) foam (VGN/Ni) is investigated. Such a structure exhibits a significant pseudocapacitive interfacial feature, greatly improving the Li+ ion transfer kinetic through the structure, and exhibiting uniform Li plating/stripping for stable Li metal cycling even at a high depth of discharge of 50%. Based on such a structure, high Coulombic efficiencies ≈97% and 99% can be obtained in carbonate and ether electrolyte over long‐term cycling. The symmetrical cell based on the VGN/Ni@Li composite anodes can afford a stable cycling of 2000 h with low voltage hysteresis of 30 mV. Full cell system using VGN/Ni@Li composite anode and LiFePO4 cathode is also proved, with high capacity retention of 89.4% at the 1000th cycle. The pseudocapacitance induced benefits, which have not yet been elucidated for Li metal anodes, can conduct to underlying strategy in designing stable Li metal host for high‐energy‐density batteries.
