Authors: Zhou Minmin , Qu Simin , Chen Xueqiu , Shi Peng , Xu Shijin , Chen Hongyu , Zhou Huiyan , Gou Jianfeng
Published: April 2019

The hydrology response was studied considering the established fact of land use change in Dapoling basin. The whole period was divided into two (1965–1985 and 1986–2012) according to the major land use and land cover change in this region. Xinanjiang model was used to simulate discharge data in the two periods. The hydrologic response to the change could be evaluated by inspecting the response of model parameters and flood elements. The results show that the lag time varied, and the hydrologic elements including the mean runoff depth, flood peak and kurtosis coefficient varied with the rainfall depth. This result is significant for studying the response of runoff characteristic from land use and land cover change.
Response of Vertical Migration and Leaching of Nitrogen in Percolation Water of Paddy Fields under Water-Saving Irrigation and Straw Return Conditions
Authors: Zheng Chengxin , Zhang Zhanyu , Wu Yunyu , Mwiya Richwell
Published: April 2019

The use of water-saving irrigation techniques has been encouraged in rice fields in response to irrigation water scarcity. Straw return is an important means of straw reuse. However, the environmental impact of this technology, e.g., nitrogen leaching loss, must be further explored. A two-year (2017–2018) experiment was conducted to investigate the vertical migration and leaching of nitrogen in paddy fields under water-saving and straw return conditions. Treatments included traditional flood irrigation (FI) and two water-saving irrigation regimes: rain-catching and controlled irrigation (RC-CI) and drought planting with straw mulching (DP-SM). RC-CI and DP-SM both significantly decreased the irrigation input compared with FI. RC-CI increased the rice yield by 8.23%~12.26%, while DP-SM decreased it by 8.98%~15.24% compared with FI. NH4+-N was the main form of the nitrogen leaching loss in percolation water, occupying 49.06%~50.97% of TN leaching losses. The NH4+-N and TN concentration showed a decreasing trend from top to bottom in soil water of 0~54 cm depth, while the concentration of NO3−-N presented the opposite behavior. The TN and NH4+-N concentrations in percolation water of RC-CI during most of the rice growth stage were the highest among treatments in both years, and DP-SM showed a trend of decreasing TN and NH4+-N concentrations. The NO3−-N concentrations in percolation water showed a regular pattern of DP-SM > RC-CI > FI during most of the rice growth stage. RC-CI and DP-SM remarkably reduced the amount of N leaching losses compared to FI as a result of the significant decrease of percolation water volumes. The tillering and jointing-booting stages were the two critical periods of N leaching (accounted for 74.85%~86.26% of N leaching losses). Great promotion potential of RC-CI and DP-SM exists in the lower reaches of the Yangtze River, China, and DP-SM needs to be further optimized.

Statistical analysis of road safety in Poland with application of taxonomic methods
Authors: Bąk Iwona , Szczecińska Beata
Published: April 2019

The road safety is an area of public security, which is a basic need of every human being. One of the sources of the threats are road traffic offenses related in violation of safety rules. The aim of the article is to analyze road safety throughout the country and in individual provinces. In the study were used spatial and time data included in e.g. in the Regional Bank Data in the years 2001-2014 and the Police research papers available on the Internet. The statistical analysis and application of the Hellwig's taxonomic measure of development allowed the characterization of road traffic offenses in Poland and to identification of regions with the highest level of road safety. It turned out, that despite the presence of a number of negative factors increasing the risk of accidents, the security situation on Polish roads improves. The number of accidents and their victims decreases. Particularly positive changes on Polish roads were noted after the Polish accession to the European Union.
Effects of gold and PCL- or PLLA-coated silica nanoparticles on brain endothelial cells and the blood–brain barrier

Published: April 2019

Nanomedicine is a constantly expanding field, facilitating and improving diagnosis and treatment of diseases. As nanomaterials are foreign objects, careful evaluation of their toxicological and functional aspects prior to medical application is imperative. In this study, we aimed to determine the effects of gold and polymer-coated silica nanoparticles used in laser tissue soldering on brain endothelial cells and the blood–brain barrier using rat brain capillary endothelial cells (rBCEC4). All types of nanoparticles were taken up time-dependently by the rBCEC4 cells, albeit to a different extent, causing a time- and concentration-dependent decrease in cell viability. Nanoparticle exposure did not change cell proliferation, differentiation, nor did it induce inflammation. rBCEC4 cells showed blood–brain barrier characteristics including tight junctions. None of the nanoparticles altered the expression of tight junctions or impaired the blood–brain barrier permeability. The findings suggest that effects of these nanoparticles on the metabolic state of cells have to be further characterized before use for medical purposes.
Cloud Coalescence: A Dynamical Instability Affecting Multiphase Environments
Authors: Waters Tim , Proga Daniel
Published: April 2019

Mass and size distributions are the key characteristics of any astrophysical object, including the densest clumps comprising the cold phase of multiphase environments. In our recent papers, we showed how individual clouds of various sizes form and evolve in active galactic nuclei. In particular, we showed that large clouds undergo damped oscillations as a response to their formation process. Here we follow up this investigation, addressing how different size clouds interact. We find that smaller clouds become trapped in the advective flows generated by larger clouds. The explanation for this behavior leads to a rather remarkable conclusion: even in the absence of gravity, complexes of clouds are dynamically unstable. In an idealized environment (e.g., one free of turbulence and magnetic fields) a perfectly symmetric arrangement of static clouds will remain static, but any small spatial perturbation will lead to all clouds coalescing into a single, large cloud, given enough time. Using numerical simulations, we investigate the main factors that determine the rate of coalescence. In addition to the cloud separation distance, we find that the transient response of clouds to a disturbance is the primary factor. Turbulent motions in the flow can easily suppress this tendency for spatially well-separated clouds to coalesce, so it is as yet unclear if this phenomenon can occur in nature. Nevertheless, this Letter casts strong doubts on a recent hypothesis that large clouds are prone to fragmentation.

Portable Surface-Enhanced Raman Scattering Sensor for the Rapid Detection of Polycyclic Aromatic Hydrocarbons in Coastal Seawater
Authors: Shi Xiaofeng , Zhang Dahai , Jia Wenjie , Yan Xia , Yang Jie , Wang Chunyan , Ma Jun
Published: April 2019

AbstractTo rapidly detect polycyclic aromatic hydrocarbons (PAHs) in coastal seawater, a portable surface-enhanced Raman scattering (SERS) sensor was designed and assembled. A large number of halide ions are present in seawater, and they easily combine with gold nanoparticles,
which results in a significant SERS enhancement effect for PAHs. Therefore, a mixture of a gold colloid solution and NaCl solution that forms a large number of highly sensitive SERS-active clusters was used in this study. The extinction intensity of the gold colloid solution at 785 nm—that
is, the SERS excitation wavelength—was greatly increased by the addition of Cl−. The SERS sensor was applied in five different coastal environments, and six or seven types of PAHs were detected without further sample processing. The seawater samples were also analyzed
using a gas chromatography-flame ionization detector (GC-FID) for comparison and confirmation of the results. Ten to 13 types of PAHs were detected by GC-FID after dehydration, purification, and concentration under nitrogen, and naphthalene was not detected because of its volatility. The SERS
sensor was proven to be a suitable alarm sensor for the in-situ detection of PAHs in coastal seawater and is proposed for use as a real-time qualitative and quantitative PAH monitoring sensor in the near future based on its promising improvement in sensitivity.

The importance of crystalline phases in ice nucleation by volcanic ash
Authors: Maters Elena C. , Dingwell Donald B. , Cimarelli Corrado , Müller Dirk , Whale Thomas F. , Murray Benjamin J.
Published: April 2019

Abstract. Volcanic ash is known to nucleate ice when immersed in
supercooled water droplets. This process may impact the properties and
dynamics of the eruption plume and cloud as well as those of meteorological
clouds once the ash is dispersed in the atmosphere. However, knowledge of
what controls the ice-nucleating activity (INA) of ash remains limited,
although it has been suggested that crystalline components in ash may play an
important role. Here we adopted a novel approach using nine pairs of tephra
and their remelted and quenched glass equivalents to investigate the
influence of chemical composition, crystallinity, and mineralogy on ash INA
in the immersion mode. For all nine pairs studied, the crystal-bearing tephra
nucleated ice at warmer temperatures than the corresponding crystal-free
glass, indicating that crystalline phases are key to ash INA. Similar to
findings for desert dust from arid and semi-arid regions, the presence of
feldspar minerals characterizes the four most ice-active tephra samples,
although a high INA is observed even in the absence of alkali feldspar in
samples bearing plagioclase feldspar and orthopyroxene. There is evidence of
a potential indirect relationship between chemical composition and ash INA,
whereby a magma of felsic to intermediate composition may generate ash
containing ice-active feldspar or pyroxene minerals. This complex interplay
between chemical composition, crystallinity, and mineralogy could help to
explain the variability in volcanic ash INA reported in the literature.
Overall, by demonstrating the importance of crystalline phases in the INA of
ash, our study contributes insights essential for better appraising the role
of airborne ash in ice formation. Among these is the inference that
glass-dominated ash emitted by the largest explosive volcanic eruptions might
be less effective at impacting ice-nucleating particle populations than
crystalline ash generated by smaller, more frequent eruptions.
HIGH-RATE TENSILE BEHAVIOR OF SILICONE RUBBER AT VARIOUS TEMPERATURES
Authors: Guo Lingmei , Wang Yang
Published: April 2019

The effects of strain rate and temperature on the tensile behavior of silicone rubber were investigated. The quasi-static uniaxial tensile experiments were conducted using an electromechanical testing system, and the high-rate uniaxial tensile tests were performed employing a modified split Hopkinson tension bar technique for low-strength and low-impedance materials. The tensile responses were obtained at strain rates of 0.001–1400 s−1 and temperatures ranging from −50 to 50 °C. The experiments reveal that the tensile stress–strain behavior of silicone rubber is nonlinear and highly dependent on strain rate and temperature. The values of stiffness and nominal stress at a given elongation increase with increased strain rate and decrease with increasing temperature. It is appropriate to postulate that the tensile response at high strain rates arises from the combination of hyperelasticity and viscoelasticity. According to the incompressibility assumption, a phenomenologically inspired visco-hyperelastic model was proposed to describe the constitutive behavior of silicone rubber over wide ranges of strain rates and temperatures.
Familia, comida y lenguaje entre los aficionados judeoargentinos del Club Atlético Atlanta
Authors: Rein Raanan
Published: April 2019

El barrio porteño de Villa Crespo y su Club Atlético Atlanta son identificados habitualmente como ―judíos. Este artículo explora el lugar de Atlanta en la vida diaria y en la cultura popular de los judíos bonaerenses. Atlanta ha servido como canal de integración social de los inmigrantes judíos y sus descendientes nacidos en Argentina en la vida urbana de Buenos Aires. Al mismo tiempo permitió a los argentinos-judíos conservar un componente de identidad étnica. El estadio de Atlanta ha provisto un lugar de encuentro para decenas de miles de judíos y no judíos, unidos por su lealtad hacia su equipo. De esta forma, Atlanta ha funcionado como espacio público de integración y como sitio de identificación entre barrio y club deportivo. De forma similar, no se puede ignorar los incidentes antisemitas que han acompañado los partidos de Atlanta y que apuntan al fútbol como espacio tanto de prejuicios como de diálogo.
Ironizando con el antisemitismo: respuestas del semanario Mundo Judío al Partido Nacional Fascista de Chile (1938-1940)
Authors: Guzmán Castro Gustavo
Published: April 2019

Durante los años treinta del siglo pasado, se produjo en Chile una proliferación de agrupaciones nacionalistas de derecha contrarias al liberalismo, la democracia y el comunismo. En algunos casos, tales agrupaciones adoptaron también el fascismo y el antisemitismo provenientes de Europa, desarrollando campañas antijudías inéditas en la Historia de Chile. El presente artículo indaga en las respuestas del semanario Mundo Judío, principal órgano de prensa de la colectividad judía chilena de los años treinta, frente al antisemitismo del Partido Nacional Fascista (PNF) de Raúl Olivares Maturana, el grupo fascista chileno más radical de los años treinta, destacando diferencias respecto de cómo se había enfrentado las provocaciones antisemitas del fascismo chileno en los años previos.

Nacionalsocialismo, Shoá, memoria: Debates historiográficos
Authors: Cyjon Ing. Roberto
Published: April 2019

Este trabajo aborda las problematizaciones interpretativas del surgimiento del nacionalsocialismo, la actuación del nazismo como actor político y ejecutor de la Shoá. Se inspira en la metodología historiográfica que presenta Enzo Traverso (2012), en su libro: La historia como campo de batalla. Traverso modera y debate con historiadores, quienes, a su vez, analizan dichos temas desde perspectivas diferentes. Seleccionaremos dos ejes centrales de dichos debates: el surgimiento del nacionalsocialismo y la Shoá como impacto remanente en la autorepresentación de la sociedad alemana. Y como conjetura adicional, cuán complejo resulta ser para el historiador de genocidios, mantener su objetividad. El campo de este trabajo, tiene como corte temporal al siglo XX. El objetivo final, por decantación, es posicionar las interpretaciones teleológicas, en una mirada actual de las dificultades vigentes en la historia política y social, acerca del uso de la memoria como recurso historiográfico.

Los “judíos progresistas” entre el retorno del peronismo y la dictadura militar en Argentina a través de la prensa (1973-1976)
Authors: Kahan Dr. Emmanuel
Published: April 2019

Como corolario a la Guerra de los Seis Días (1967) y las repercusiones en el debate político que suscitó aquella contienda bélica en Argentina, la Federación de Instituciones Culturales Judías de la República Argentina, el ICUF, promovió una nueva publicación desde la cual daría a conocer sus diversos posicionamientos frente a conflictos de diversa índole: la situación en Medio Oriente, la vida cultural judía en la Unión Soviética, los conflictos de las organizaciones comunitarias locales y el estado de la situación política, económica y cultural en Argentina. Desde entonces y hasta 1987, cuando deja de editarse la publicación icufista, las páginas de Tiempo serían testimonio de las transformaciones y continuidades de la conflictividad política al interior de los ámbitos comunitarios y, a su vez, de las tensas relaciones y configuraciones de sentidos de la política nacional argentina. El presente trabajo indagará en los diversos posicionamientos y narrativas que esgrimieron los redactores de Tiempo durante un período singular de la historia política argentina: desde la asunción presidencial de Héctor Cámpora (1973) hasta el inicio de la última dictadura militar en Argentina (1976).

En el presente artículo se da cuenta de los resultados de un estudio cualitativo acerca de las diferentes condiciones que permiten comprender la obediencia civil en regímenes dictatoriales, y específicamente acerca de cómo se puede entender este fenómeno durante la Alemania nacionalsocialista. Esta problemática ha rondado constantemente el debate sociológico y filosófico del siglo XX acerca del Holocausto. Aquí se busca responder esta pregunta a través del rescate de la memoria y de la experiencia de los inmigrantes judíos-alemanes que vivieron el nazismo en Alemania (1933-1945), y arrancando de él llegaron a Chile. Se da cuenta de la obediencia civil como un fenómeno social complejo, dentro del cual se pueden rastrear una serie condiciones contextuales, intervinientes, causales e interacciones para comprender el acuerdo público y privado frente al régimen dictatorial.
Hannah Arendt: el judío de excepción y su fracaso en el proceso de integración a la sociedad alemana en la modernidad
Authors: Calderón Paula
Published: April 2019

En este trabajo analizaremos, siguiendo los planteamientos realizados por Hannah Arendt, cómo se produjo la asimilación entre la cultura europea moderna con la cultura judía en el contexto que rodea la emancipación de este pueblo en la Alemania del siglo XVIII. Para ello, se seguirán los planteamientos realizados por la pensadora en los textos La Ilustración y la cuestión judía y Los orígenes del totalitarismo. Para llevar a cabo este proceso, reflexionaremos en torno a la hipótesis de lectura que construye la autora bajo dos imágenes ideales, centrándose en dos tipos humanos que para la filósofa alemana expresarán a dos modelos de judíos concretos: el judío culto de excepción y el judío de excepción de la riqueza. Por este motivo, para comprender este período, seguiremos el desarrollo de estas dos figuras arquetípicas, las que contienen una "validez ejemplar" para la filósofa alemana.

Published: April 2019

There will be elaborated several facts about creativity in Twenty First-Century educational reforms in six countries(The US, India, Chile, Mexico, China, and Singapore). The crucial source of the content in the paper relies on thebook, “Teaching and Learning for the Twenty-First Century” (Reimeres and Chung, 2016). Nevertheless, myexploration of creativity in modern education in the six countries has a limited range. Creativity depends on threemeaningful factors of education such as equality, quality and implementing modern educational reforms. The papersheds light on similarities and differences of six countries that they experience with the three factors (equality,creativity, and implementing modern educational reforms). All countries strive to apply equality in the whole country,although, none of the countries has employed equality throughout the nation. Some countries made better progress onapplying equality in education, and others are facing many obstacles with equal education throughout the country.Creativity is significant to every educational system, and it is interrelated with equality and applying modern education.The US system of education applies creativity in a few school districts. Other countries state creativity in theircurriculum, but they do not use it in the classrooms at all. Six countries have different economic development, anddifferent economic demands; therefore, they have different approaches to implementing modern educational reforms.Despite the fact all countries have dissimilarities with implementing creativity in educational reforms, they all knowcreativity’s weight in modern education. Creativity as a first step of the innovation that defines the progress ofeducation especially accelerates the growth of the entire economy within a society.
Did Tom Brady Save the US stock market? Market Anomaly or Market Efficiency?
Authors: Amoateng Kofi A.
Published: April 2019

This study reexamines how the National Football conference (NFC) Super Bowl predictor influences investors’ sentiment to affect U.S. stock market returns from 1967 to 2018. The overall empirical evidence significantly supports the NFC predictor-stock market relationship. Even continuous Super Bowl wins by Tom Brady’s New England Patriots could not overturn the Super Bowl stock market predictor (SBSMP). The false positive evidence by the NFC Super Bowl continues to provide investors with extraordinary returns. While the evidence is positive, there is a need for more theoretical research on the SBSMP. The Super Bowl euphoria can create a multiplier effect on the winning team’s local economy and overall stock market (Edmans et al., 2007) and (Palomino et al., 2009). This anomaly has demonstrated that an investor would have outperformed the market by using the Super bowl indicator. However, its predictive power is statistically declining but empirically significant (Thompson & Sen, 2017).
A novel dopamine electrochemical sensor based on La3+/ZnO nanoflower modified graphite screen printed electrode
Authors: Tajik Somayeh , Beitollahi Hadi , Aflatoonian Mohammad Reza
Published: April 2019

Flower-like La3+/ZnO nanocomposite was facile synthesized. A simple and ultrasensitive sensor based on graphite screen printed electrode (SPE) modified by La3+/ZnO nanoflower was developed for the electrochemical determination of dopamine. The electrochemical behavior of dopamine was studied in 0.1 M phosphate buffer solution (PBS) using cyclic voltammetry (CV), chronoamperometry (CA) and differential pulse voltammetry (DPV). Compared with the unmodified graphite screen printed electrode, the modified electrode facilitates the electron transfer of dopamine, since it notably increases the oxidation peak current of dopamine. Also, according to CV results the maximum oxidation of dopamine on La3+/ZnO/SPE occurs at 150 mV which is about 140 mV more negative compared with unmodified SPE. Under optimized conditions, the modified electrode exhibited a linear response over the concentration range from 0.15 to 300.0 μM, with a detection limit of 0.08 μM (S/N = 3). The proposed sensor exhibited a high sensitivity, good stability and was successfully applied for dopamine determination in dopamine ampoule, with high recovery.

A Comparison of Standard Practice Treatments in Research Library Book Conservation, 2007 to 2017
Authors: Baker Whitney S.
Published: April 2019

In 2007, a web-based survey of book conservation practices was conducted to document standard-practice, moderate-use, and low-use book conservation treatments for general and special collections in research libraries in the United States. This paper reports on the findings of a ten-year follow-up survey conducted in 2017 to determine whether and how book conservation treatment practices have changed over the last ten years. Overall, the data indicate that while general collections treatment practices have remained consistent, special collections practices continue to evolve, with many treatments newly qualifying as standard practice in the special collections context since 2007. The data also suggest areas of further research, including how demographic factors may correlate with particular treatment practices.
Digital narratives on entrance exams for the Brazilian secondary school: ego-documents and written culture in history of the present time
Authors: Silva Cristiani Bereta da
Published: April 2019

The proposal of this article is discussing digital narratives written in the first person, taken in their widest sense as ego-documents. We analyzed 12 blogs and 4 personal websites that provide written stories on entrance exams for the Brazilian secondary school (which were in force in Brazil between 1931 and 1971), as well as comments related to each post. The analysis of narratives was conducted having three irreducibly interconnected axes as a basis: the first one is methodological and requires discussing the possibilities and limits of exploring blogs and websites as adequate historical sources to grasp the contemporary phenomena of memory, narrative, and temporalities. The second axis implies analyzing narratives posted on blogs and websites as phenomena that contribute to provide the history of written culture in the present time with intelligibility. The third axis of analysis imposes thinking through meanings of the past and memory in the writings of one’s own. The issues raised herein deal with challenges of the meaning and interpretation of time by subjects of the present. If we take into account that narrating one’s life is a transcultural need related to the sense of existence, we must not give up thinking of changes that take place in human experience and its relation to historicity after hyper-connectivity, which became possible through the web 2.0, has significantly altered the flows of time and space. Keywords: Written culture. Digital narratives. Entrance exam for the Brazilian secondary school.
A long present: the role played by the press in the Brazilian redemocratization process – The Folha de S. Paulo in 1974
Authors: Lohn Reinaldo Lindolfo
Published: April 2019

This article aims at exploring theoretical possibilities that allow us to discuss the political narrative of Brazilian democratization, a process usually situated from 1974 onwards, when a so-called political distension was announced by the military dictatorship. A narrative constructed by the big press, which emerged as one of the privileged democratization voices, this established the prominence of certain political and social players and sectors. The study focus lies on the newspaper Folha de S. Paulo, whose pages provided a prominent place for the negotiations involving the Brazilian political system and the appreciation of elections as a way of institutionalizing the regime. Keywords: Redemocratization.

Penggunaan insektisida golongan piretroid secara luas dan terus menerus dalam pencegahan penularan malaria dapat menimbulkan mutasi gen voltage gate sodium channel (VGSC) pada vektor nyamuk yang dikenal dengan mutasi knockdown resistance (kdr). Mutasi gen ini membuat sensitifitas ikatan protein VGSC dengan insektisida menurun sehingga menyebabkan resistensi. Timbulnya resistensi insektisida piretroid pada nyamuk vektor dapat menjadi penghambat keberhasilan pemutusan penularan penyakit malaria sehingga deteksi adanya mutasi mutlak diperlukan. Tujuan penelitian ini untuk mengetahui status resistensi insektisida piretroid dan mengidentifikasi mutasi pada gen VGSC kodon 1014 penanda resistensi nyamuk Anopheles sp. yang menjadi vektor malaria di Provinsi Sumatera Selatan. Sampel diambil di tiga Kabupaten, yaitu Muara Enim, Ogan  Komering Ulu (OKU), dan Lahat. Uji awal kerentanan terhadap insektisida piretroid (permetrin 0,75%) dilakukan sesuai standar WHO tahun 2016 pada spesies dominan, yaitu Anopheles vagus Dönitz. Selanjutnya, identifikasi mutasi gen VGSC pada kodon 1014 dilakukan pada An. vagus dan spesies Anopheles barbirostris van der Wulp yang tertangkap, dengan teknik seminested-PCR dan dilanjutkan dengan analisis sekuensing. Hasil uji kerentanan Anopheles sp. di Kabupaten Muara Enim menunjukkan resisten terhadap piretroid, sedangkan di Kabupaten Lahat dan OKU masih rentan terhadap insektisida piretroid. Sementara, analisis sekuensing PCR menunjukkan tidak terjadi perubahan basa alel kdr pada target site insektisida gen VGSC sehingga dapat disimpulkan secara molekuler belum ditemukan adanya mutasi pada gen VGSC kdr allel penanda resistensi insektisida piretroid.
La précieuse « boëte » de Marie-Josèphe. Trajectoire d’une boîte, écrin d’une vie

In 1790, in the small village of Petite-Rivière-Saint-François, nestled between the mountain and the Saint Lawrence River, a woman lued a handwritten note inside a box. Fearing that the box could be stolen, she threatened anyone who took it with harsh punishment. Why? This article explores the box’s possible origins, its provenance, and its acquisition by ethnologist Marius Barbeau in 1930. Fundamental aspects of the woman’s life will also be addressed, examining various aspects of the sociocultural history of the Charlevoix and Côte de Beaupré regions of Québec at the end of the 18th century. The article covers two intertwining stories: the story of an object, Mi’Kmaq in origin or influence, and the story of a habitante and her world.
An enigmatic decoupling between heat stress and coral bleaching on the Great Barrier Reef
Authors: DeCarlo Thomas , Harrison Hugo B
Published: April 2019

Ocean warming threatens the functioning of coral reef ecosystems by inducing mass coral bleaching and mortality events. The link between temperature and coral bleaching is now well-established based on observations that mass bleaching events usually occur when seawater temperatures are anomalously high. However, times of high heat stress but without coral bleaching are equally important because they can inform an understanding of factors that mitigate temperature-induced bleaching. Here, we investigate the absence of mass coral bleaching on the Great Barrier Reef (GBR) during austral summer 2004. Using four gridded sea surface temperature (SST) data products, validated with in situ temperature loggers, we demonstrate that the summer of 2004 was among the warmest summers of the satellite era (1982-2017) on the GBR. At least half of the GBR experienced temperatures that were high enough to initiate bleaching in other years, yet mass bleaching was not reported during 2004. The absence of bleaching is not fully explained by wind speed or cloud cover. Rather, 2004 is clearly differentiated from bleaching years by the slow speed of the East Australian Current (EAC) offshore of the GBR. An anomalously slow EAC during summer 2004 may have dampened the upwelling of nutrient-rich waters onto the GBR shelf, potentially mitigating bleaching due to the lower susceptibility of corals to heat stress in low-nutrient conditions. Although other factors such as irradiance or acclimatization may have played a role in the absence of mass bleaching, 2004 remains a key case study for demonstrating the dynamic nature of coral responses to marine heatwaves.
Reporter-ChIP-nexus reveals strong contribution of the Drosophila initiator sequence to RNA polymerase pausing

RNA polymerase II (Pol II) pausing is a general regulatory step in transcription, yet the stability of paused Pol II varies widely between genes. Although paused Pol II stability correlates with core promoter elements, the contribution of individual sequences remains unclear, in part because no rapid assay is available for measuring the changes in Pol II pausing as a result of altered promoter sequences. Here, we overcome this hurdle by showing that ChIP-nexus captures the endogenous Pol II pausing on transfected plasmids. Using this reporter-ChIP-nexus assay in Drosophila cells, we show that the pausing stability is influenced by downstream promoter sequences, but that the strongest contribution to Pol II pausing comes from the initiator sequence, in which a single nucleotide, a G at the +2 position, is critical for stable Pol II pausing. These results establish reporter-ChIP-nexus as a valuable tool to analyze Pol II pausing.
Precise excitation-inhibition balance controls gain and timing in the hippocampus

Published: April 2019

Excitation-inhibition (EI) balance controls excitability, dynamic range, and input gating in many brain circuits. Subsets of synaptic input can be selected or 'gated' by precise modulation of finely tuned EI balance, but assessing the granularity of EI balance requires combinatorial analysis of excitatory and inhibitory inputs. Using patterned optogenetic stimulation of mouse hippocampal CA3 neurons, we show that hundreds of unique CA3 input combinations recruit excitation and inhibition with a nearly identical ratio, demonstrating precise EI balance at the hippocampus. Crucially, the delay between excitation and inhibition decreases as excitatory input increases from a few synapses to tens of synapses. This creates a dynamic millisecond-range window for postsynaptic excitation, controlling membrane depolarization amplitude and timing via subthreshold divisive normalization. We suggest that this combination of precise EI balance and dynamic EI delays forms a general mechanism for millisecond-range input gating and subthreshold gain control in feedforward networks.
The Cas4-Cas1-Cas2 complex mediates precise prespacer processing during CRISPR adaptation
Authors: Lee Hayun , Dhingra Yukti , Sashital Dipali G
Published: April 2019

CRISPR adaptation immunizes bacteria and archaea against viruses. During adaptation, the Cas1-Cas2 complex integrates fragments of invader DNA as spacers in the CRISPR array. Recently, an additional protein Cas4 has been implicated in selection and processing of prespacer substrates for Cas1-Cas2, although this mechanism remains unclear. We show that Cas4 interacts directly with Cas1-Cas2 forming a Cas4-Cas1-Cas2 complex that captures and processes prespacers prior to integration. Structural analysis of the Cas4-Cas1-Cas2 complex reveals two copies of Cas4 that closely interact with the two integrase active sites of Cas1, suggesting a mechanism for substrate handoff following processing. We also find that the Cas4-Cas1-Cas2 complex processes single-stranded DNA provided in cis or in trans with a double-stranded DNA duplex. Cas4 cleaves precisely upstream of PAM sequences, ensuring the acquisition of functional spacers. Our results explain how Cas4 cleavage coordinates with Cas1-Cas2 integration and defines the exact cleavage sites and specificity of Cas4.

INTRODUCTION Since the 2000s, interest in research data management (RDM) has grown considerably. As a result, a large body of literature has discussed a broad variety of aspects related to data management. But, few studies have examined and also interpreted from visual perception the intellectual structure and progressive development of the existing literature on RDM. METHODS Guided by five research questions, this study employed bibliometric techniques and a visualization tool (CiteSpace) to identify and analyze the patterns of the scholarly publications about RDM. RESULTS Through CiteSpace’s modeling and computing, the knowledge (or network) structures, significant studies, notable topics, and development trends in the literature of RDM were revealed. DISCUSSION The majority of the literature pertinent to RDM was published after 2002. Major research clusters within this interdisciplinary field include “scientific collaboration,” “research support service,” and “data literacy,” while the “scientific collaboration” research cluster was the most active. Topics such as “digital curation” and “information processing” appeared most frequently in the RDM literature. Additionally, there was a sharp increase in several specific topics, such as “digital library,” “big data,” and “data sharing.” CONCLUSION By looking into the “profile” of the literature on RDM, in terms of knowledge structure, evolving trends, and important topics in the domain, this work will add new information to current discussions about RDM, new service development, and future research focuses in this area.

Background

Variation in management across elephant camps likely has differential effects on the well-being of elephants.

Methods

This study calculated body condition, foot health and skin wound scores (WSs) for 122 elephants from 15 elephant camps in Chiang Mai province, and examined relationships to management factors using a multi-variable modeling approach.

Results

The majority of elephants had high body condition scores (BCS) indicative of being overweight or obese, mild foot problems, but few visible wounds. Females had higher BCSs than males, as did elephants provided a water source at night. Increasing age was associated with higher foot and WSs. Higher WSs were observed in about a quarter of the cases where mahouts carried a hook. Wounds related to saddle riding were rare. Elephants that rested on sand floors at night had a decreased risk of high WSs compared to elephants that rested on compact dirt floors.

Discussion

Findings emphasize the need for elephant camps to adjust management activities that negatively affect body condition (e.g., feeding too many sweet treats), foot health (e.g., hard substrates) and wounding (e.g., misuse of equipment) to improve health and welfare of this population.
