Petrography and geochemistry of the Carboniferous–Triassic Trinity Peninsula Group, West Antarctica: implications for provenance and tectonic setting
Authors: CASTILLO PAULA , LACASSIE JUAN PABLO , AUGUSTSSON CARITA , HERVÉ FRANCISCO 
Published: September 2014

AbstractThe Carboniferous-Triassic Trinity Peninsula Group is a metasedimentary sequence that crops out widely in the northern Antarctic Peninsula. These are some of the most extensive outcrops in the area and hold the key to evaluating the connections of the Antarctic Peninsula in Gondwana; however, they are still poorly understood. Here we present our provenance study of the Trinity Peninsula Group using petrographic and geochemical approaches in combination with cathodoluminescence of detrital quartz in order to constrain its source characteristics and tectonic setting. Using differences in modal composition and quartz cathodoluminescence characteristics, we define three petrofacies derived from the progressive uplift and erosion of a volcano-plutonic continental arc, which exposed the plutonic-metamorphic roots. As indicated by major and trace elements, the source is felsic with a composition ranging from tonalitic to granodioritic. The relatively unweathered condition of the source area points to a dry and cold climate at the time of deposition, but this does not necessarily mean that it was glaciated. Deposition of the sediments occurred within an active continental margin, relatively close to the source area, probably along the south Patagonia–Antarctic Peninsula sector of Gondwana. Strong chronological, petrological and chemical similarities with the sediments of the Duque the York Complex in Patagonia suggest that they were derived from the same source.
Secularizing the Sacred, Imagining the Nation-Space: The Himalaya in Bengali travelogues, 1856–1901
Authors: BANERJEE SANDEEP , BASU SUBHO 
Published: September 2014

AbstractThis article examines changing conceptions of the Himalaya in nineteenth-century Bengali travelogues from that of a sacred space to a spatial metaphor of a putative nation-space. It examines sections of Devendranath Tagore's autobiography, written around 1856–58, before discussing the travelogues of Jaladhar Sen and Ramananda Bharati from the closing years of the nineteenth century. The article argues that for Tagore the mountains are the ‘holy lands of Brahma’, while Sen and Bharati depict the Himalaya with a political slant and secularize the space of Hindu sacred geography. It contends that this process of secularization posits Hinduism as the civil religion of India. The article further argues that the later writers make a distinction between the idea of a ‘homeland’ and a ‘nation’. Unlike in Europe, where the ideas of homeland and nation overlap, these writers imagined the Indian nation-space as one that encompassed diverse ethno-linguistic homelands. It contends that the putative nation-space articulates the hegemony of the Anglo-vernacular middle classes, that is, English educated, upper caste, male Hindus where women, non-Hindus, and the labouring classes are marginalized.
Fictional IR and imagination: Advancing narrative approaches
Authors: PARK-KANG SUNGJU 
Published: September 2014

AbstractIn the field of International Relations (IR), narrative approaches and an alternative way of writing seem to have gained growing attention in recent scholarship. Autoethnography and autobiography can be taken as primary examples. The article aims to advance this growing scholarship by proposing the concept of fictional IR. The idea is concerned with how to use the imagination in IR. I suggest that fiction writing can become a method for dealing with lack of information and contingency surrounding it. Fictional IR is more than reading and using fiction as a reference source or vehicle for analysis. It can incorporate the employment of fiction writing in IR scholarship. One of the benefits could be to articulate sensitive and complicated problems in a more flexible and imaginative way, making the most of the power of story and imagination. It should be stressed that the focal point is to write fiction; it is not to write about fiction. To support this suggestion, the article offers a short fictional-factual story. By using imagination, creating characters, combining data with fictional narrative, or with one's own experience, I believe that more original and empathetic IR writing is possible.
A dynamics based two-stage path model for the docking navigation of a self-assembly modular robot (Sambot)

Published: September 2014

SUMMARYAutonomous docking is a focus of research in the field of self-assembly robots. Navigation is a significant stage in the process of autonomous docking between two robotic modules; it determines the efficiency of docking and even the success and failure of the docking task. In most cases, it is too difficult to simultaneously satisfy both linear and angular displacement constraints in a single dynamic numerical computation process. In the present paper, the navigation process is divided into two stages: first, the angular displacement constraint is satisfied, and then the linear displacement condition is fulfilled. In this way, the constraints are loosened and the difficulty of numerical computation is thereby effectively reduced. This two-stage docking navigation model is the main contribution of the present work. By taking the non-holonomic nature of the navigation behavior into consideration, both kinematic and dynamic analyses are performed, and the voltage data of the DC motors required by the two-stage docking navigation are obtained. Finally, docking navigation experiments are completed on a self-assembly modular robot named Sambot. It is verified that the present two-stage strategy is effective in controlling the docking navigation process.
Developing communicative competence: a longitudinal study of the acquisition of mental state terms and indirect requests
Authors: DE MULDER HANNAH 
Published: September 2014

ABSTRACTThis longitudinal study involving 101 Dutch four- and five-year-olds charts indirect request (IR) and mental state term (MST) understanding and investigates the role that Theory of Mind (ToM) and general linguistic ability (vocabulary, syntax, and spatial language) play in this development. The results showed basic understanding of IR and MST in four-year-olds, but full understanding had not been reached even at five years old. Furthermore, although ToM predicted both IR and MST when linguistic ability was not taken into account, this relationship was no longer significant once the language measures were added. Linguistic ability thus seems to play an important role in the development of both IR and MST. Additional analyses revealed that whereas syntactic ability was the primary predictor of IR, spatial language was the best predictor of MST, suggesting that IR relies primarily on general linguistic skills, but that more specific aspects of language may bootstrap MST.
On the distribution of the zeros of the derivative of the Riemann zeta-function
Authors: LESTER STEPHEN 
Published: September 2014

AbstractWe establish an asymptotic formula describing the horizontal distribution of the zeros of the derivative of the Riemann zeta-function. For ℜ(s) = σ satisfying (log T)−1/3+ε ⩽ (2σ − 1) ⩽ (log log T)−2, we show that the number of zeros of ζ′(s) with imaginary part between zero and T and real part larger than σ is asymptotic to T/(2π(σ−1/2)) as T → ∞. This agrees with a prediction from random matrix theory due to Mezzadri. Hence, for σ in this range the zeros of ζ′(s) are horizontally distributed like the zeros of the derivative of characteristic polynomials of random unitary matrices are radially distributed.
Poor embryo development and preimplantation genetic diagnosis outcomes of translocations involving chromosome 10: Do we blame genetics?
Authors: Tulay P. , Gultomruk M. , Findikli N. , Bahceci M. 
Published: September 2014

SummaryBalanced reciprocal translocation carriers are usually phenotypically normal. Although the reproductive risk of these carriers varies, they generally have a lower chance to produce normal or balanced gametes. Preimplantation genetic diagnosis (PGD) is offered to these patients to increase their chances of becoming pregnant by selecting a balanced embryo for transfer. This study aimed to analyse the development and the PGD outcome of the embryos obtained from reciprocal translocation carriers focusing on ones with chromosome 10 rearrangements. In total, 27 reciprocal translocation carriers underwent 31 cycles of PGD. PGD was performed using multicolour fluorescencein situhybridisation for 298 embryos and of these 136 were obtained from couples carrying translocations involving chromosome 10 rearrangements. Carriers of translocations involving chromosome 10 rearrangements have a lower chance of producing normal or balanced embryos compared with the carriers with other rearrangements. The development of embryos obtained from the patients with chromosome 10 rearrangements was impaired and only a limited number of embryos developed to the blastocyst stage.

AbstractTo date, it is unclear whether chemical order (or disorder) is in any way connected to double exchange, electronic phase separation, or charge ordering (CO) in manganites. In this work, we carry out an atomic resolution study of the colossal magnetoresistant manganite La2−2xSr1+2xMn2O7 (LSMO). We combine aberration-corrected electron microscopy and spectroscopy with spectroscopic image simulations, to analyze cation ordering at the atomic scale in real space in a number of LSMO single crystals. We compare three different compositions within the phase diagram: a ferromagnetic metallic material (x=0.36), an insulating, antiferromagnetic charge ordered (AF-CO) compound (x=0.5), which also exhibits orbital ordering, and an additional AF sample (x=0.56). Detailed image simulations are essential to accurately quantify the degree of chemical ordering of these samples. We find a significant degree of long-range chemical ordering in all cases, which increases in the AF-CO range. However, the degree of ordering is never complete nor can it explain the strongly correlated underlying ordering phenomena. Our results show that chemical ordering over distinct crystallographic sites is not needed for electronic ordering phenomena to appear in manganites, and cannot by itself explain the complex electronic behavior of LSMO.

AbstractUsing a genome-scale, lentivirally delivered shRNA library, we performed massively parallel pooled shRNA screens in 216 cancer cell lines to identify genes that are required for cell proliferation and/or viability. Cell line dependencies on 11,000 genes were interrogated by 5 shRNAs per gene. The proliferation effect of each shRNA in each cell line was assessed by transducing a population of 11M cells with one shRNA-virus per cell and determining the relative enrichment or depletion of each of the 54,000 shRNAs after 16 population doublings using Next Generation Sequencing. All the cell lines were screened using standardized conditions to best assess differential genetic dependencies across cell lines. When combined with genomic characterization of these cell lines, this dataset facilitates the linkage of genetic dependencies with specific cellular contexts (e.g., gene mutations or cell lineage). To enable such comparisons, we developed and provided a bioinformatics tool to identify linear and nonlinear correlations between these features.

AbstractThe leishmaniases are neglected tropical diseases of significant public health importance. However, information on their global occurrence is disparate and sparse. This database represents an attempt to collate reported leishmaniasis occurrences from 1960 to 2012. Methodology for the collection of data from the literature, abstraction of case locations and data processing procedures are described here. In addition, strain archives and online data resources were accessed. A total of 12,563 spatially and temporally unique occurrences of both cutaneous and visceral leishmaniasis comprise the database, ranging in geographic scale from villages to states. These data can be used for a variety of mapping and spatial analyses covering multiple resolutions.
The combination of high Q factor and chirality in twin cavities and microcavity chain

Published: September 2014

AbstractChirality in microcavities has recently shown its bright future in optical sensing and microsized coherent light sources. The key parameters for such applications are the high quality (Q) factor and large chirality. However, the previous reported chiral resonances are either low Q modes or require very special cavity designs. Here we demonstrate a novel, robust and general mechanism to obtain the chirality in circular cavity. By placing a circular cavity and a spiral cavity in proximity, we show that ultra-high Q factor, large chirality and unidirectional output can be obtained simultaneously. The highest Q factors of the non-orthogonal mode pairs are almost the same as the ones in circular cavity. And the co-propagating directions of the non-orthogonal mode pairs can be reversed by tuning the mode coupling. This new mechanism for the combination of high Q factor and large chirality is found to be very robust to cavity size, refractive index and the shape deformation, showing very nice fabrication tolerance. And it can be further extended to microcavity chain and microcavity plane. We believe that our research will shed light on the practical applications of chirality and microcavities.

Published: September 2014

A subsampling filter is proposed for a discrete‐time receiver (DTR). This filter achieves signal discretisation, filtering and downconversion simultaneously. With the proposed subsampling filtering technique, the subsampling mixer in a conventional DTR is eliminated, which can reduce power, cost and noise. The first 2.4 GHz DTR prototype for Zigbee application is fabricated in a 0.18 μm CMOS process. It achieves 23 dB conversion gain, 17.6 dB noise figure and −15 dBm IIP3. Operated from a single 1 V supply, the low‐noise amplifier and following filter stages consume only 3.8 mW and the total receiver power consumption is 25.6 mW.

3‐T ISFET front‐end utilising parasitic device capacitance
Authors: Hu Yuanqi , Georgiou Pantelis 
Published: September 2014

A 3‐T ion sensitive field effect transistor (ISFET) chemical sensor that utilises the parasitic drain–gate capacitance of the device is proposed. It is compact and consumes extremely low power, and at the same time is immune to capacitive division. Additionally, it provides in‐pixel amplification dependent on the ratio of passivation and feedback (parasitic) capacitance. The fabricated sensor achieves 200 mV/pH sensitivity using this amplification mechanism.
Trapping Effects and Fisheries Research: A Case Study of Sockeye Salmon in the Wenatchee River, USA

Published: September 2014

ABSTRACT
Trapping facilities are regularly used to achieve a variety of fishery research and management goals. Though care of sampled organisms is a central tenet of most agencies, the effects of trapping on fish behavior are seldom quantified. We used passive integrated transponder technology to calculate passage delay and blockage of adult Sockeye Salmon at a facility where all spring-migrating fishes were trapped for research between 2008 and 2010. Median passage delay ranged from 0.4 to 8.7 days, and 8% to 38% of the return (2,387 to 21,090 adults) was precluded from reaching upriver spawning habitat. A protocol limiting trapping to less than 24 h per week was implemented in 2011 and median delay decreased to 6 min, with the result being that nearly all fish were able to ascend to spawning grounds for two consecutive years. The annual variation in delay was unrelated to run size or river flow, indicating that research activities requiring intensive trapping operations had inadvertently blocked tens of thousands of adult salmon from reaching spawning tributaries. We use this case study to advocate the adoption of a precautionary approach where trapping of adult migratory fishes is proposed but the effects are unknown.
RESUMEN
las instalaciones para el entrampamiento normalmente se utilizan en el cumplimiento de diversas investigaciones pesqueras y objetivos de manejo. Mientras que el cuidado de los organismos muestreados representa uno de los temas centrales para la mayoría de las agencias, los efectos del entrampamiento en la conducta de los peces son raramente cuantificados. Se utilizó un transponedor pasivo integrado para calcular el retraso y bloqueo durante el paso de salmones rojos adultos en instalaciones en las que todos los peces migrantes de primavera fueron asegurados para su posterior investigación entre 2008 y 2010. La mediana del retraso durante el paso varió de 0.4 a 8.7 días y se impidió que entre 8% y 38% (2,387 a 21,090 adultos) de los individuos regresaran al hábitat de desove. Se implementó un protocolo para limitar el entrampamiento a menos de 24 horas por semana y la mediana del retraso disminuyó a 6 minutos, dando como resultado que casi todos los peces fueran capaces de ascender a las áreas de desove durante dos años consecutivos. La variación anual en el retraso del paso resultó ser independiente del tamaño de la corrida y de la magnitud del flujo, indicando que las actividades de investigación que requieren de operaciones de entrampamiento han bloqueado de manera inadvertida el paso de decenas de miles de salmones adultos hacia sus sitios de desove en los tributarios. Se utilizó este caso de estudio para abogar por la adopción de un enfoque precautorio en el que se propone el entrampamiento de peces migratorios adultos aunque su efecto se desconozca.
Open-Access Databases as Unprecedented Resources and Drivers of Cultural Change in Fisheries Science
Authors: McManamay Ryan A , Utz Ryan M 
Published: September 2014

ABSTRACT
Open-access databases with utility in fisheries science have grown exponentially in quantity and scope over the past decade, with profound impacts to our discipline. The management, distillation, and sharing of an exponentially growing stream of open-access data represents several fundamental challenges in fisheries science. Many of the currently available open-access resources may not be universally known among fisheries scientists. We therefore introduce many national- and global-scale open-access databases with applications in fisheries science and provide an example of how they can be harnessed to perform valuable analyses without additional field efforts. We also discuss how the development, maintenance, and utilization of open-access data are likely to pose technical, financial, and educational challenges to fisheries scientists. Such cultural implications that will coincide with the rapidly increasing availability of free data should compel the American Fisheries Society to actively address these problems now to help ease the forthcoming cultural transition.
RESUMEN
en la última década, el número de bases de datos de acceso abierto con utilidad para la ciencia pesquera ha crecido exponencialmente en cantidad y alcance y su impacto ha sido considerado como muy importante en esta disciplina. El manejo, depuración e intercambio de datos de acceso abierto representa retos fundamentales en la ciencia pesquera. Muchos de los recursos actualmente disponibles de acceso abierto pueden no ser conocidos por los científicos pesqueros. Por lo tanto, aquí se presentan varias bases de datos a nivel nacional e internacional de libre acceso con aplicación en las ciencias pesqueras y se da un ejemplo de cómo pueden ser aprovechadas para realizar valiosos análisis sin hacer esfuerzos adicionales de trabajo de campo. También se discute cómo el desarrollo, mantenimiento y uso de las base de datos de libre acceso muy posiblemente representarán retos importantes para los científicos de la pesca en cuanto a las dimensiones técnica, financiera y educativa. Tales implicaciones culturales, que coincidirán con la disponibilidad cada vez mayor de datos gratuitos, debieran servir de impulso a la Sociedad Americana de Pesquerías a que volcara activamente su atención sobre estos problemas con el fin de facilitar la transición cultural que se avecina.
