Plant DNA viruses of the genus Begomovirus have been documented as the most genetically diverse in the family Geminiviridae and present a serious threat for global horticultural production, especially considering climate change. It is important to characterize naturally existing begomoviruses, since viral genetic diversity in non-cultivated plants could lead to future disease epidemics in crops. In this study, high-throughput sequencing (HTS) was employed to determine viral diversity of samples collected in a survey performed during 2012–2016 in seven states of Northern-Pacific Mexico, areas of diverse climatic conditions where different vegetable crops are subject to intensive farming. In total, 132 plant species, belonging to 34 families, were identified and sampled in the natural ecosystems surrounding cultivated areas (agro-ecological interface). HTS analysis and subsequent de novo assembly revealed a number of geminivirus-related DNA signatures with 80 to 100% DNA similarity with begomoviral sequences present in the genome databank. The analysis revealed DNA signatures corresponding to 52 crop-infecting and 35 non-cultivated-infecting geminiviruses that, interestingly, were present in different plant species. Such an analysis deepens our knowledge of geminiviral diversity and could help detecting emerging viruses affecting crops in different agro-climatic regions.
MR-WC-MPS: A Multi-Resolution WC-MPS Method for Simulation of Free-Surface Flows
Authors: Nabian Mohammad Amin , Farhadi Leila
Published: July 2019

A Multi-Resolution Weakly Compressible Moving-Particle Semi-Implicit (MR-WC-MPS) method is presented in this paper for simulation of free-surface flows. To reduce the computational costs, as with the multi-grid schemes used in mesh-based methods, there is also a need in particle methods to efficiently capture the characteristics of different flow regions with different levels of complexity in different spatial resolutions. The proposed MR-WC-MPS method allows the use of particles with different sizes in a computational domain, analogous to multi-resolution grid in grid-based methods. To evaluate the accuracy and efficiency of the proposed method, it is applied to the dam-break and submarine landslide tests. It is shown that the MR-WC-MPS results, while about 15% faster, are in good agreement with the conventional single-resolution MPS results and experimental results. The remarkable ability of the MR-WC-MPS method in providing robust savings in computational time for up to 60% is then shown by applying the method for simulation of extended submarine landslide test.
Estimation of Reservoir Sediment Flux through Bottom Outlet with Combination of Numerical and Empirical Methods
Authors: Huang Cheng-Chia , Lin Wen-Cheng , Ho Hao-Che , Tan Yih-Chi
Published: July 2019

Sediment deposition issues for reservoirs are important in Taiwan because the severe deposition could excessively decrease the reservoir lifecycle. Extreme storm events usually can carry a massive amount of sediment into reservoirs, and deposition will happen unless the incoming material can pass through sluice gates. When it comes with high concentration, the density current flow is prone to be generated, and the bottom outlets are the most effective sluice gate to release the sediment. In order to improve the sediment release efficiency, an accurate estimation of arriving concentration and time of the density current can be useful for the reservoir management. This study develops a two-stage approach which combines a numerical model (SRH2D) and the modified Rouse equation to predict the sediment flux of the reservoir. The numerical model was verified and applied to establish the relation between inflow and dam face concentration. The modified Rouse equation then adopted this relation to estimate the proper exponential parameter. As a result, the sediment flux amount at each bottom outlet can be accurately predicted by this equation. With this means, an early warning system can be established for reservoir operation, which can improve release efficiency during typhoons.
Using Cosmic-Ray Neutron Probes in Validating Satellite Soil Moisture Products and Land Surface Models
Authors: Duygu Mustafa Berk , Akyürek Zuhal
Published: July 2019

Soil moisture content is one of the most important parameters of hydrological studies. Cosmic-ray neutron sensing is a promising proximal soil moisture sensing technique at intermediate scale and high temporal resolution. In this study, we validate satellite soil moisture products for the period of March 2015 and December 2018 by using several existing Cosmic Ray Neutron Probe (CRNP) stations of the COSMOS database and a CRNP station that was installed in the south part of Turkey in October 2016. Soil moisture values, which were inferred from the CRNP station in Turkey, are also validated using a time domain reflectometer (TDR) installed at the same location and soil water content values obtained from a land surface model (Noah LSM) at various depths (0.1 m, 0.3 m, 0.6 m and 1.0 m). The CRNP has a very good correlation with TDR where both measurements show consistent changes in soil moisture due to storm events. Satellite soil moisture products obtained from the Soil Moisture and Ocean Salinity (SMOS), the METOP-A/B Advanced Scatterometer (ASCAT), Soil Moisture Active Passive (SMAP), Advanced Microwave Scanning Radiometer 2 (AMSR2), Climate Change Initiative (CCI) and a global land surface model Global Land Data Assimilation System (GLDAS) are compared with the soil moisture values obtained from CRNP stations. Coefficient of determination ( r 2 ) and unbiased root mean square error (ubRMSE) are used as the statistical measures. Triple Collocation (TC) was also performed by considering soil moisture values obtained from different soil moisture products and the CRNPs. The validation results are mainly influenced by the location of the sensor and the soil moisture retrieval algorithm of satellite products. The SMAP surface product produces the highest correlations and lowest errors especially in semi-arid areas whereas the ASCAT product provides better results in vegetated areas. Both global and local land surface models’ outputs are highly compatible with the CRNP soil moisture values.
Hybrid Methodology for the Estimation of Crop Coefficients Based on Satellite Imagery and Ground-Based Measurements
Authors: Spiliotopoulos Marios , Loukas Athanasios
Published: July 2019

The objective of the current study was the investigation of specific relationships between crop coefficients and vegetation indices (VI) computed at the water-limited environment of Lake Karla Watershed, Thessaly, in central Greece. A Mapping ET (evapotranspiration) at high Resolution and with Internalized Calibration (METRIC) model was used to derive crop coefficient values during the growing season of 2012. The proposed methodology was developed using medium resolution Landsat 7 ETM+ images and meteorological data from a local weather station. Cotton, sugar beets, and corn fields were utilized. During the same period, spectral signatures were obtained for each crop using the field spectroradiometer GER1500 (Spectra Vista Corporation, NY, U.S.A.). Relative spectral responses (RSR) were used for the filtering of the specific reflectance values giving the opportunity to match the spectral measurements with Landsat ETM+ bands. Normalized Difference Vegetation Index (NDVI), Soil Adjusted Vegetation Index (SAVI) and Enhanced Vegetation Index 2 (EVI2) were then computed, and empirical relationships were derived using linear regression analysis. NDVI, SAVI, and EVI2 were tested separately for each crop. The resulting equations explained those relationships with a very high R2 value (>0.86). These relationships have been validated against independent data. Validation using a new image file after the experimental period gives promising results, since the modeled image file is similar in appearance to the initial one, especially when a crop mask is applied. The CROPWAT model supports those results when using the new crop coefficients to estimate the related crop water requirements. The main benefit of the new approach is that the derived relationships are better adjusted to the crops. The described approach is also less time-consuming because there is no need for atmospheric correction when working with ground spectral measurements.
Flood Risk Analysis for Cascade Dam Systems: A Case Study in the Dadu River Basin in China
Authors: Cai Wenjun , Zhu Xueping , Peng Anbang , Wang Xueni , Fan Zhe
Published: July 2019

To quantify the flood risks in cascade dam systems, it is critical to analyze the risk factors and potential breaking failure paths. In this study, Bayesian networks (BNs) were applied to create a flood risk analysis model for a cascade dam system. Expert experiment, historical data, and computational formulas were employed to estimate the prior probability and original conditional probability tables (CPTs) in the BN model; sensitivity analysis was used to ensure the original continuous breaking failure path in the system. To avoid the possible misperceptions of the probability of a certain event, Dam Breach Analysis Model (DB-IWHR) 2014 software and the flood regulation method were used to simulate the dam breaking progress. The posteriori continuous breaking failure paths were obtained, and then the original CPTs were refined based on the new evidence. The proposed method was applied to the Bala-Busigou-Shuangjiangkou (BL-BSG-SJK), which is located upstream of the Dadu River basin in China. The results show that three continuous breaking failure paths could be identified in the researched cascade dam system. A new BN model was created to determine the failure probability of the cascade dam system under the three continuous breaking failure paths. This analytical method may also be useful for other similar cases.
Music and Ritual in Trebbus Mevlevi Tekke (Lodge) in Germany
Authors: ÖKSÜZOĞLU Osman
Published: July 2019

Germany is one of the countries in Europe with a very large
Muslim population. Therefore, it is possible to see many different Sufi groups
there. One of these Sufi groups is the Mevlevis. The first Mevlevi tekke
(lodge) was founded in the 1990s in Germany under the name of Mevlevi
Association (Verein). Today there are two different Mevlevi groups, which are located
in Nurnberg and Trebbus. The Trebbus Tekke is the place where the Mevlevi order
is represented along with the Kubrevi order. The purpose of this article is to
analyze music in rituals in the Trebbus Mevlevi Tekke in Germany, document the
contemporary development of the German rituals, and investigate the effect of
different cultural contexts and cultural influences on the nature of the
resulting communities.
Itineraries of Enlightenment: Whirling Dervish Shows, Ethnographic Reflexivity, and Tourism in Egypt and Turkey
Authors: VICENTE Victor
Published: July 2019

By the year 2010, both Turkey and Egypt had achieved tremendous success in growing their tourism markets, in part by turning to Sufi spiritual and musical practices, which had by then been internally rehabilitated after being historically met with suspicion or outright suppression even as they gained a global following in the New Spiritualties and World Music arenas. Taking the case of the so-called ‘whirling dervish show,’ this article traces how its characteristic ‘dance’ was strategically used to promote tourism and how rituals featuring it were adapted for presentation to ever-bigger audiences coming from abroad. Based on ethnographic research conducted in Cairo and throughout Turkey, the article demonstrates how binary distinctions between tourist and pilgrim, sacred and profane, and local and foreign, become quickly blurred or contested at these shows and in other sacred settings involving travel. Further embedding the musical ethnographer within these vagaries, the article seeks two main ends: to call for an ethnomusicological method that better accounts for tourists and their subjective experiences and, thereby, to also encourage more open reflexive framework in which the fieldworker working in tourist and tourist-like settings can better take stock of their own positionality while in situ and when engaging in the writing of ethnography.

Imaging and printing in plastic and reconstructive surgery part 1: established techniques
Authors: Chae Michael Park , Hunter-Smith David , Rozen Warren
Published: July 2019

Background: An increasing number of reconstructive surgeons are using modern imaging technologies for preoperative planning and intraoperative surgical guidance. Conventional imaging modalities such as CT and MRI are relatively affordable and widely accessible and offer powerful functionalities. In the first of a two-part series, we evaluate established three-dimensional (3D) imaging and printing techniques based on CT and MRI used in plastic and reconstructive surgery.
Method: A review of the published English literature dating from 1950 to 2017 was taken using databases such as PubMed, MEDLINE®, Web of Science and EMBASE.
Result: In plastic and reconstructive surgery, the most commonly used, free software platforms are 3D Slicer (Surgical Planning Laboratory, Boston, MA, USA) and OsiriX (Pixmeo, Geneva, Switzerland). Perforator mapping using 3D-reconstructed images from computed tomography angiography (CTA) and magnetic resonance angiography (MRA) is commonly used for preoperative planning. Three-dimensional volumetric analysis using current software techniques remains labour-intensive and reliant on operator experience. Three-dimensional printing has been investigated extensively since its introduction. As more free open-source software suites and affordable 3D printers become available, 3D printing is becoming more accessible for clinicians.
Conclusion: Numerous studies have explored the application of 3D-rendered conventional imaging modalities for perforator mapping, volumetric analysis and printing. However, there is a lack of comprehensive review of all established 3D imaging and printing techniques in a language suitable for clinicians.

Nükleer tehlikeler, atomun parçalanması ya da iki atomun
birleşmesi ile açığa çıkan enerjinin kontrolsüz olarak yayılması ve çevreyi
etkilemesi olarak tanımlanabilir. Radyoaktif materyallerin tutulduğu tesislerde
oluşabilecek kazalar sonucunda radyasyon salınımı ortaya çıkabilmektedir. Bu
tesislerde meydana gelen kazaların sebepleri arasında öngörülemeyen insan
hatalarının yanı sıra deprem, sel ve tsunami gibi doğal afetler de yer
almaktadır. Geniş bir çevreyi etkileyebilecek böylesi bir olayda, radyasyon
salınımının durdurulması ve radyasyona maruz kalmanın engellenmesi gibi hayati
önem taşıyan bir dizi eylem gerçekleştirilmesi gerekmektedir. Kısıtlı bir zaman
diliminde ve sınırlı imkânlarla gerçekleştirilmesi gereken eylemleri kapsayan
bu sürecin başarısı, afet öncesi korumaya yönelik yapılan hazırlık
çalışmalarının etkinliğine bağlıdır. Öte yandan gerçekleştirilecek eylemlerin organizasyonu
ve kaynakların yönetimi için coğrafi bilgi sistemleri (CBS) tabanlı karar
destek sistemlerine ihtiyaç duyulmaktadır.

Bu çalışmada öncelikle radyasyon türleri ve radyasyonun
canlılar üzerindeki etkileri açıklanmış, ardından nükleer ve radyolojik
tehlikeler, komşu ülkelerde bulunan nükleer santrallerin oluşturduğu riskler de
göz önüne alınarak Türkiye açısından değerlendirilmiştir. Ayrıca yeni kurulacak
nükleer güç santralleri için deprem tehlikesinin belirlenmesi amacıyla
yapılması gereken çalışmalar ve Türkiye’deki durum değerlendirilmiştir. Bununla
birlikte nükleer ve radyolojik tehlikelere karşı afet yönetimi kapsamında
ülkemizde gerçekleştirilen hazırlık çalışmaları incelenerek bir durum

Este artículo parte de un error en el que algunos medios incurrieron al construir la noticia de la muerte de Eliseo Verón. La investigación se remonta a sus años de joven estudiante y a sus primeros escritos publicados por CENTRO, revista del Centro de es- tudiantes de la facultad de Filosofía y Letras, en el contexto de los agitados movimientos de intelectuales en los años 50s. El texto recupera fragmentos de un Verón habitualmen- te desconocido, que asumía tempranamente su posición de enunciador crítico hacia los poderes instituidos y portavoz de un estudiantado convocado a reclamar la integración democrática en el gobierno universitario.
Homenaje a Eliseo Verón, en asociación.
Authors: Valdettaro Sandra
Published: July 2019

La figura y la obra de Eliseo Verón son centrales en la constitución del CIM (Centro de Investigaciones en Mediatizaciones), fundado en 2011 en la Universidad Nacional de Ro- sario, Argentina. Su objeto de estudio es el campo de las “mediatizaciones” bajo el supues- to de la creciente complejidad de los procesos comunicativos que involucran tecnologías mediáticas. El abordaje epistemológico, teórico y metodológico de los fenómenos bajo estudio en las distintas investigaciones radicadas en el CIM se funda en la perspectiva so- cio-semiótica de Eliseo Verón, en diálogo transdisciplinar con otros enfoques provenientes de las Ciencias Sociales y Humanas.
De los medios a los fenómenos mediáticos: el despliegue del concepto de mediatización en la obra de Eliseo Verón
Authors: Fernández Mariano
Published: July 2019

Si bien el concepto de mediatización puede rastrearse en la obra de Eliseo Verón desde principios de la década de 1980, sólo en su último libro, La semiosis Social 2, que presentó una concepción orgánica. A diferencia de las investigaciones que en los últimos años, y particularmente en Europa, han conformado un campo de discusión muy activo, Verón nunca redujo el concepto al fenómeno de los medios masivos de comunicación. De allí la importancia que adquiere en sus textos la relación entre tres conceptos: dis- positivos tecnológicos, medios de comunicación y fenómenos mediáticos, que habilitan un estudio extendido de la mediatización, más allá y más acá de la modernidad. Fundamentar esta línea de lectura es el propósito de este artículo.
Siluetas ternarias. Las represen- taciones de la noción de semiosis social
Authors: Soto Marita
Published: July 2019

En el artículo se propone un recorrido por las distintas formas de representación visual de la noción de semiosis social en la obra de Eliseo Verón. La semiosis del propio concepto transparenta la trayectoria que va desde un momento inicial en el que se enfatiza la con- dición de materialidad de la semiosis hasta uno en el que se manifiesta la imposibilidad de tener una metodología certera para trabajar sobre el desfase entre las instancias de producción y reconocimiento, ambas fases de la semiosis. Se trata entonces de encontrar aproximaciones en la construcción de las hipótesis sobre los efectos posibles de un proceso de significación.
Eliseo Verón, la soledad del saber
Authors: Fisher Sophie
Published: July 2019

Este articulo narra los anos de formación de Eliseo Veron en la Facultad de Filosofía y Letras de la Universidad de Buenos Aires a partir de 1955, año que coincide con la caída del gobierno de Juan Domingo Perón y el inicio de una renovación en la vida universitaria donde Veron participará activamente en la revista Centro, órgano del Centro de Estudiantes de dicha facultad. El título de esta contribución está tomado del homenaje que Veron realiza a Lévi-Strauss en ocasión de su muerte. Muestra ya el descubrimiento y la transición hacia la semiología prefigurando los cursos que dará luego en la École des Hautes Études en Sciences Sociales a partir de los años 1973. Roland Barthes fue quien lo introdujo en la institución y lo hizo nombrar Director de Estudios asociado, cuando Veron vuelve a Paris para establecerse por un largo periodo. Por último la tercera parte de esta contribución remite a la « interfaz » entre teoría y práctica social con una investigación para la RATP (la poderosa red de subterráneos de Paris) que fue una de las primeras tentativas de interacción entre la investigación universitaria y la sociedad, prefigurando lo que sería en los años 80 y 90 su trabajo como profesional en estudios de Semiotica aplicada.
Recetas para leer a Eliseo Verón
Authors: Traversa Oscar
Published: July 2019

Este articulo presenta cuatro claves de lectura a la obra de Eliseo Veron, colega
y amigo del autor. Interrogándose sobre el paso del modelo binario, clásico de la epistemología estructuralista – que Veron contribuyo a instalar no solo en Argentina sino en América Latina- al modelo ternario de semiosis luego de la lectura del semiólogo y filosofo americano Charles S. Peirce, Traversa explora las formas en que Veron construye su propia epistemología.
Use of DNA Barcoding to Control the Illegal
Wildlife Trade: A CITES Case Report from
Pakistan

Published: July 2019

Illegal wildlife trade is a great threat to the conservation efforts made worldwide to save wildlife
species and their parts. Use of molecular methods, including DNA barcoding, is gaining
acceptance to detect cross-border movement of endangered species. Here we report the utility of
DNA barcoding in the detection of smuggling of an endangered turtle species from Pakistan. The
consignment labeled as “fish meat” was intercepted at a Pakistani port and was tested for its
source using DNA Barcoding with fish-specific primers. Sequences from the samples from this
consignment matched (99%) with those from Lissemys punctata (Indian flap-shelled turtle), a
species listed by the Convention on International Trade in Endangered Species (CITES). This
report highlights the problem of smuggling protected species under false pretenses and the
importance of DNA barcoding in stopping such illegal trade.

Azologization of a hetero-stilbene based c-RAF kinase inhibitor: Towards the design of photoswitchable sirtuin inhibitors

Published: July 2019

The use of light as an external trigger to change ligand shape and as a result its bioactivity, allows the probing of pharmacologically relevant systems with spatiotemporal resolution. In this context, aromatic diazeno compounds are well suited for the design of photoswitchable ligands due to the long thermal relaxation half‐lives of the photoinduced Z configuration, and tunability of the absorption wavelength λ
max. In search for sirtuin inhibitors, a hetero-stilbene lead resulting from the screening of a compound that was originally designed as kinase inhibitor, was remodelled to its diazeno analogue. By this azologization, the shape of the molecule was left unaltered whereas the photoswitching ability was improved. As anticipated, the highly analogous compound showed similar activity in its thermodynamically stable stretched-out E form. Irradiation of this isomer triggers isomerisation to the Z configuration with a bent geometry causing a considerably shorter end‐to‐end distance. The resulting affinity shifts are intended to enable real‐time photomodulation of sirtuins in vitro.
Phosphorous-doped green-emission fluorescent carbon dots sensing for pH, lemon yellow and the antioxidant application

Published: July 2019

In this paper, we reported green-emission carbon dots (CDs) using a single step hydrothermal carbonization. The CDs were prepared by m-phenylenediamine, tris, phosphoric acid, and pure water by heating for 8 h at 180 ℃. The CDs exhibited green-emission fluorescence, were sensitive to pH, and was successfully used analysed the pH of real water samples. Besides, the CDs could detect of food additive lemon yellow, with the limit of detection as low as 0.13 μM. More importantly, the CDs could be used as an antioxidant to remove superoxide anions (O2-) and hydroxyl radicals (–OH). The linear range of CDs concentrations for superoxide anion and hydroxyl radicals were 0 - 300 mg/mL and 0 - 14 mg/mL, respectively. In addition, the CDs could be a fluorescnet reagent in bioimaging of beer yeast, mould and onion skins. The favorable pH, optical properties, antioxidant ability, and bioimaging ability ensure the CDs can be exploited in food analysis and other fields.

We present an analysis of instrument performance using new observations taken with the Coronagraphic High Angular Resolution Imaging Spectrograph (CHARIS) instrument and the Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) system. In a correlation analysis of our data sets (which use the broadband mode covering the J band through the K band in a single spectrum), we find that chromaticity in the SCExAO/CHARIS system is generally worse than temporal stability. We also develop a point-spread function (PSF) subtraction pipeline optimized for the CHARIS broadband mode, including a forward modeling-based exoplanet algorithmic throughput correction scheme. We then present contrast curves using this newly developed pipeline. An analogous subtraction of the same data sets using only the H-band slices yields the same final contrasts as the full JHK sequences; this result is consistent with our chromaticity analysis, illustrating that PSF subtraction using spectral differential imaging (SDI) in this broadband mode is generally not more effective than SDI in the individual J, H, or K bands. In the future, the data processing framework and analysis developed in this paper will be important to consider for additional SCExAO/CHARIS broadband observations and other ExAO instruments which plan to implement a similar integral field spectrograph broadband mode.
AXS: A Framework for Fast Astronomical Data Processing Based on Apache Spark

Published: July 2019

We introduce AXS (Astronomy eXtensions for Spark), a scalable open-source astronomical data analysis framework built on Apache Spark, a widely used industry-standard engine for big-data processing. Building on capabilities present in Spark, AXS aims to enable querying and analyzing almost arbitrarily large astronomical catalogs using familiar Python/AstroPy concepts, DataFrame APIs, and SQL statements. We achieve this by (i) adding support to Spark for efficient on-line positional cross-matching and (ii) supplying a Python library supporting commonly used operations for astronomical data analysis. To support scalable cross-matching, we develop a variant of the ZONES algorithm capable of operating in distributed, shared-nothing architecture. We couple this to a data partitioning scheme that enables fast catalog cross-matching and handles the data skew often present in deep all-sky data sets. The cross-match and other often-used functionalities are exposed to the end users through an easy-to-use Python API. We demonstrate AXS’s technical and scientific performance on Sloan Digital Sky Survey, Zwicky Transient Facility, Gaia DR2, and AllWise catalogs. Using AXS we were able to perform on-the-fly cross-match of Gaia DR2 (1.8 billion rows) and AllWise (900 million rows) data sets in ∼30 s. We discuss how cloud-ready distributed systems like AXS provide a natural way to enable comprehensive end-user analyses of large data sets such as the Large Synoptic Survey Telescope.
