Real-Time GNSS-Based Attitude Determination in the Measurement Domain
Authors: Zhao Lin , Li Na , Li Liang , Zhang Yi , Cheng Chun
Published: February 2017

A multi-antenna-based GNSS receiver is capable of providing high-precision and drift-free attitude solution. Carrier phase measurements need be utilized to achieve high-precision attitude. The traditional attitude determination methods in the measurement domain and the position domain resolve the attitude and the ambiguity sequentially. The redundant measurements from multiple baselines have not been fully utilized to enhance the reliability of attitude determination. A multi-baseline-based attitude determination method in the measurement domain is proposed to estimate the attitude parameters and the ambiguity simultaneously. Meanwhile, the redundancy of attitude resolution has also been increased so that the reliability of ambiguity resolution and attitude determination can be enhanced. Moreover, in order to further improve the reliability of attitude determination, we propose a partial ambiguity resolution method based on the proposed attitude determination model. The static and kinematic experiments were conducted to verify the performance of the proposed method. When compared with the traditional attitude determination methods, the static experimental results show that the proposed method can improve the accuracy by at least 0.03° and enhance the continuity by 18%, at most. The kinematic result has shown that the proposed method can obtain an optimal balance between accuracy and reliability performance.
Augmented Reality Tool for the Situational Awareness Improvement of UAV Operators
Authors: Ruano Susana , Cuevas Carlos , Gallego Guillermo , García Narciso
Published: February 2017

Unmanned Aerial Vehicles (UAVs) are being extensively used nowadays. Therefore, pilots of traditional aerial platforms should adapt their skills to operate them from a Ground Control Station (GCS). Common GCSs provide information in separate screens: one presents the video stream while the other displays information about the mission plan and information coming from other sensors. To avoid the burden of fusing information displayed in the two screens, an Augmented Reality (AR) tool is proposed in this paper. The AR system has two functionalities for Medium-Altitude Long-Endurance (MALE) UAVs: route orientation and target identification. Route orientation allows the operator to identify the upcoming waypoints and the path that the UAV is going to follow. Target identification allows a fast target localization, even in the presence of occlusions. The AR tool is implemented following the North Atlantic Treaty Organization (NATO) standards so that it can be used in different GCSs. The experiments show how the AR tool improves significantly the situational awareness of the UAV operators.
Queer in STEM Organizations: Workplace Disadvantages for LGBT Employees in STEM Related Federal Agencies
Authors: Cech Erin , Pham Michelle
Published: February 2017

Lesbian, gay, bisexual, and transgender (LGBT) individuals in U.S. workplaces often face disadvantages in pay, promotion, and inclusion and emergent research suggests that these disadvantages may be particularly pernicious within science and engineering environments. However, no research has systematically examined whether LGBT employees indeed encounter disadvantages in science, technology, engineering and math (STEM) organizations. Using representative data of over 30,000 workers employed in six STEM-related federal agencies (the Department of Energy, the Environmental Protection Agency, the National Science Foundation, NASA, the Nuclear Regulatory Commission, and the Department of Transportation), over 1000 of whom identify as LGBT, we compare the workplace experiences of LGBT employees in STEM-related federal agencies with those of their non-LGBT colleagues. Across numerous measures along two separate dimensions of workplace experiences—perceived treatment as employees and work satisfaction—LGBT employees in STEM agencies report systematically more negative workplace experiences than their non-LGBT colleagues. Exploring how these disadvantages vary by agency, supervisory status, age cohort, and gender, we find that LGBT persons have more positive experiences in regulatory agencies but that supervisory status does not improve LGBT persons’ experiences, nor do the youngest LGBT employees fare better than their older LGBT colleagues. LGBT-identifying men and women report similar workplace disadvantages. We discuss the implications of these findings for STEM organizations and STEM inequality more broadly.
Stochastic Differential Equation Models for the Price of European CO2 Emissions Allowances
Authors: Cai Wugan , Pan Jiafeng
Published: February 2017

Understanding the stochastic nature of emissions allowances is crucial for risk management in emissions trading markets. In this study, we discuss the emissions allowances spot price within the European Union Emissions Trading Scheme: Powernext and European Climate Exchange. To compare the fitness of five stochastic differential equations (SDEs) to the European Union allowances spot price, we apply regression theory to obtain the point and interval estimations for the parameters of the SDEs. An empirical evaluation demonstrates that the mean reverting square root process (MRSRP) has the best fitness of five SDEs to forecast the spot price. To reduce the degree of smog, we develop a new trading scheme in which firms have to hand many more allowances to the government when they emit one unit of air pollution on heavy pollution days, versus one allowance on clean days. Thus, we set up the SDE MRSRP model with Markovian switching to analyse the evolution of the spot price in such a scheme. The analysis shows that the allowances spot price will not jump too much in the new scheme. The findings of this study could contribute to developing a new type of emissions trading.
A Study on Immersion of Hand Interaction for Mobile Platform Virtual Reality Contents
Authors: Han Seunghun , Kim Jinmo
Published: February 2017

This study proposes gaze-based hand interaction, which is helpful for improving the user’s immersion in the production process of virtual reality content for the mobile platform, and analyzes efficiency through an experiment using a questionnaire. First, three-dimensional interactive content is produced for use in the proposed interaction experiment while presenting an experiential environment that gives users a high sense of immersion in the mobile virtual reality environment. This is designed to induce the tension and concentration of users in line with the immersive virtual reality environment. Additionally, a hand interaction method based on gaze—which is mainly used for the entry of mobile virtual reality content—is proposed as a design method for immersive mobile virtual reality environment. The user satisfaction level of the immersive environment provided by the proposed gaze-based hand interaction is analyzed through experiments in comparison with the general method that uses gaze only. Furthermore, detailed analysis is conducted by dividing the effects of the proposed interaction method on user’s psychology into positive factors such as immersion and interest and negative factors such as virtual reality (VR) sickness and dizziness. In this process, a new direction is proposed for improving the immersion of users in the production of mobile platform virtual reality content.
A Hierarchal Risk Assessment Model Using the Evidential Reasoning Rule
Authors: Ji Xiaoxiao , Jiang Jiang , Sun Jianbin , Chen Yu-Wang
Published: February 2017

This paper aims to develop a hierarchical risk assessment model using the newly-developed evidential reasoning (ER) rule, which constitutes a generic conjunctive probabilistic reasoning process. In this paper, we first provide a brief introduction to the basics of the ER rule and emphasize the strengths for representing and aggregating uncertain information from multiple experts and sources. Further, we discuss the key steps of developing the hierarchical risk assessment framework systematically, including (1) formulation of risk assessment hierarchy; (2) representation of both qualitative and quantitative information; (3) elicitation of attribute weights and information reliabilities; (4) aggregation of assessment information using the ER rule and (5) quantification and ranking of risks using utility-based transformation. The proposed hierarchical risk assessment framework can potentially be implemented to various complex and uncertain systems. A case study on the fire/explosion risk assessment of marine vessels demonstrates the applicability of the proposed risk assessment model.

Annual Changes in Seasonal River Water Temperatures in the Eastern and Western United States
Authors: Wagner Tyler , Midway Stephen , Whittier Joanna , DeWeber Jefferson , Paukert Craig
Published: February 2017

Changes in river water temperatures are anticipated to have direct effects on thermal habitat and fish population vital rates, and therefore, understanding temporal trends in water temperatures may be necessary for predicting changes in thermal habitat and how species might respond to such changes. However, many investigations into trends in water temperatures use regression methods that assume long-term monotonic changes in temperature, when in fact changes are likely to be nonmonotonic. Therefore, our objective was to highlight the need and provide an example of an analytical method to better quantify the short-term, nonmonotonic temporal changes in thermal habitat that are likely necessary to determine the effects of changing thermal conditions on fish populations and communities. To achieve this objective, this study uses Bayesian dynamic linear models (DLMs) to examine seasonal trends in river water temperatures from sites located in the eastern and western United States, regions that have dramatically different riverine habitats and fish communities. We estimated the annual rate of change in water temperature and found little evidence of seasonal changes in water temperatures in the eastern U.S. We found more evidence of warming for river sites located in the western U.S., particularly during the fall and winter seasons. Use of DLMs provided a more detailed view of temporal dynamics in river thermal habitat compared to more traditional methods by quantifying year-to-year changes and associated uncertainty, providing managers with the information needed to adapt decision making to short-term changes in habitat conditions that may be necessary for conserving aquatic resources in the face of a changing climate.
Un ensemble funéraire du début du Bronze final à Aix-en-Provence (Bouches-du-Rhône) : les sépultures secondaires à crémation du site du Conservatoire
Authors: Aujaleu Ariane , Granier Gaëlle , Lachenal Thibault
Published: February 2017

The urban requalification of southern areas of the city of Aix-en-Provence led to an archaeological excavation on a plot where the future academy of music and dance (‘ Conservatoire’) is to be built. It brought to light five secondary cremation graves which can be dated to the beginning of the Late Bronze Age. This discovery illustrates a specific practice not very well-known in Southern France for that period. These small graves each contained only a funerary urn in which were found the remains of a single individual, sometimes accompanied by small fragments of animal bones but without any trace of the funerary pyre. The graves are sealed by a sort of pebble tumulus which rests upon the cover of the funerary urn, made of a small limestone slab in one case and probably of some perishable material in three other cases. These small mounds could also be interpreted as visual marks for the location of the graves. A crushed pot close to one of the graves may also be considered as a funerary deposit. Anthropological studies show that the bones were partially collected from the primary cremation structure. However, great variability can be observed between the different tombs regarding the quantity of bones and the anatomical parts selected. The typology of the urns indicates that they belong to an advanced phase of the Late Bronze Age I, 13th century BC, which is confirmed by 14C dates from the carbonates remaining in the burnt bones. The study of burial behaviour regarding the structure of the tombs reveals similarities with contemporaneous cemeteries in north-western Italy dated to the Late Bronze II and, in particular, with Canegrate in Lombardy. This new funerary group thus confirms the Transalpine origin of the practice of cremation in southern France at the beginning of the Late Bronze Age and constitutes its most western example. Unlike other cemeteries discovered in eastern Provence, the " Conservatoire" cemetery is located in an area where the influence of northern Italian ceramic productions is less important. While the funerary practices are related to Italian practices the urns themselves belong to the local style. It is the sign of a partial acculturation, testifying that the lower Rhone valley at that time was a buffer zone between traditions found to the North and the South of the Alps. Finally, this discovery invites us to question the importance of cremation in the funerary practices of southern populations at the beginning of the Late Bronze Age. Indeed, until now, the few graves belonging to this type were only known in the Alp regions, close to Italy. They were thus interpreted as linked to a specific status of the deceased or as the result of individual mobility. Now, we may wonder whether the data available reflect reality or whether they depend, on the contrary, on the difficulty of identifying small funerary groups such as the one unearthed in Aix-en-Provence.

Etude comparative de la végétation des étangs du Forez et de Dombes
Authors: Lebreton Philippe
Published: February 2017

Une étude a été conduite de la végétation aquatique du Forez et de la Dombes, régions d'étangs semi-naturels de France moyenne.

Les étangs foréziens sont quelque peu moins divers et moins fournis : 23,2 espèces végétales en moyenne par étang, contre 31,6 en Dombes ; 10 espèces foréziennes se ren¬ contrent avec une fréquence égale ou supérieure à 68 %, contre le double en Dombes ; la végétation couvre en moyenne les 6/10lmes d'un étang dombiste, la moitié seulement en Forez. Alors que la typhaie est la formation majeure en Forez, glycériaie-sparganiaie et associations flottantes occupent chacune le tiers de la végétation aquatique en Dombes.

Une analyse multivariée assoit également cette comparaison. La relative pauvreté des étangs foréziens relève de trois causes : leur caractère plus artificiel, leurs plus grandes pente et profondeur moyennes, leur isolement biogéographique. Des données sont également apportées concernant la structure des peuplements floristiques en milieu d'étangs.

Apparition normale et apparition différée de la prédation chez Euborellia moesta (Géné) (Dermaptera, Carcinophoridae)
Authors: Blancheteau Marc
Published: February 2017

Le comportement prédateur caractéristique du Dermaptère Euborellia moesta (Géné) apparaît en général dès le début du 2e stade larvaire. On a élevé 30 larves en ne les nourrissant que de proies mortes et d'aliments végétaux ; une fois adultes, on a offert des proies vivantes à ces animaux afin d'observer s'ils y réagiraient par le comportement typique de l'espèce et s'ils les captureraient. Les résultats montrent que l'inutilisaton des réactions de prédation durant la vie larvaire n'a pas supprimé ni gêné leur manifestation au stade adulte. On n'a noté qu'une certaine imprécision des mouvements de préhension lors des tout premiers essais.
Xerobates Agassiz, 1857, synonyme plus ancien de Scaptochelys Bramble, 1982 (Reptilia, Chelonii, Testudinidae)
Authors: Bour Roger , Dubois Alain
Published: February 2017

Xerobates agassiz, 1857, synonymous older than Scaptochelys Bramble, 1982 (Reptilia, Chelonii, Testudinidae) . — Recently, Bramble (1982) proposed to split the north-american testudinid genus Gopherus Rafinesque, 1832 into two genera. For the first genus, he retained the name Gopherus Rafinesque, 1832 (type-species, by original designation, Testudo polyphemus Daudin, 1801). For the second one, he created the name Scaptochelys Bramble, 1982 (type-species, by original designation, Xerobates agassizii Cooper, 1863). However he overlooked the existence of an available name for this second genus, namely Xerobates Agassiz, 1857 (type-species, by subsequent designation of Brown (1908), Xerobates berlandieri Agassiz, 1857), which must therefore replace Scaptochelys as the valid name of this genus.

Multimodal cantilevers with novel piezoelectric layer topology for sensitivity enhancement
Authors: Moore Steven Ian , Ruppert Michael G , Yong Yuen Kuan
Published: February 2017

Self-sensing techniques for atomic force microscope (AFM) cantilevers have several advantageous characteristics compared to the optical beam deflection method. The possibility of down scaling, parallelization of cantilever arrays and the absence of optical interference associated imaging artifacts have led to an increased research interest in these methods. However, for multifrequency AFM, the optimization of the transducer layout on the cantilever for higher order modes has not been addressed. To fully utilize an integrated piezoelectric transducer, this work alters the layout of the piezoelectric layer to maximize both the deflection of the cantilever and measured piezoelectric charge response for a given mode with respect to the spatial distribution of the strain. On a prototype cantilever design, significant increases in actuator and sensor sensitivities were achieved for the first four modes without any substantial increase in sensor noise. The transduction mechanism is specifically targeted at multifrequency AFM and has the potential to provide higher resolution imaging on higher order modes.
Comparison of four methods for the biofunctionalization of gold nanorods by the introduction of sulfhydryl groups to antibodies
Authors: Wang Xuefeng , Mei Zhong , Wang Yanyan , Tang Liang
Published: February 2017

Introducing sulfhydryl groups to biomolecules to functionalize gold nanorods (GNRs) is an attractive method that involves the creation of a strong Au–S bond. Previously, we developed a facile method to functionalize GNR surfaces by thiolating antibodies using Traut’s reagent. In the current study, we evaluated several methods for the introduction of thiol groups onto the surface of GNRs by using Traut’s reagent, dithiotreitol (DTT), dithiolaromatic PEG6-CONHNH2, and thiol-polyethylene glycolamine (SH-PEG-NH2) combined with EDC reaction. We showed that the four above-mentioned thiolation methods can efficiently functionalize GNRs and simplify the functionalization procedures. The formed GNR-bioconjugates showed superior stability without compromising the biological activity. The GNR nanochip prepared with these four thiolated antibodies can detect human IgG targets with specificity. However, SH-PEG-NH2 combined with EDC reaction may affect the amount of functionalized GNRs because of the efficiency of thiol moiety linkage to antibodies, thereby affecting the sensitivity of the GNR sensor. The introduction of a thiol group to antibodies by using Traut’s reagent, DTT, and PEG6-CONHNH2 allowed for direct immobilization onto the GNR surface, improved the efficacy of functionalized GNRs, and increased the sensitivity in response to target detection as a biosensor. Given that PEG6-CONHNH2 modification requires glycosylated biomolecules, Traut’s reagent and DTT thiolation are recommended as universal applications of GNR biofunctionalization and can be easily extended to other sensing applications based on other gold nanostructures or new biomolecules.
Revisiting Chagas disease and its cardiac implications: an integrative review study for nursing practice
Authors: Batista Santos Vinicius , Alves Pereira Nathalia Cristina , Dos Santos Mariana Alvina , Lopes Moreira Rita Simone , Machado Regimar Carla
Published: February 2017

Goals: Identify relevant aspects found in the literature regarding nursing actions in caring for adults with Chagas cardiomyopathy.

Methods: An integrative review was performed. The research was guided by the question: "What information and actions should nurses know about when taking care of adults with Chagas cardiomyopathy?"

Results: Eleven articles were identified, published in the last 10 years. This study showed that: patients with Chagas cardiomyopathy have more severe symptoms than with other etiologies of heart failure and higher prevalence of indications for artificial heart pacemakers; there is a knowledge gap among health professionals regarding this disease; and these patients face prolonged hospital stays until heart transplantation with a consequent drop in their quality of life, calling for interventions with a focus on self-management of the disease. 

Conclusions: The planning of nursing interventions that result in improved quality of life, symptom control, and increased adherence to pharmacological and non-pharmacological therapy is essential in the care of patients with Chagas disease.

Keywords: nursing, Chagas disease, Chagas cardiomyopathy

Objective: To propose a care protocol for the care of the person with a venous ulcer in highly complex services.

Methods and results: This is a methodological study, in three stages: literature review, validation of content and validation in the clinical context. The literature review was carried out from June to August/2011, being the basis for the construction of the Protocol for Venous Ulcers. The content validation included 53 judges (44 nurses, 8 physicians and 1 physiotherapist) selected through the Lattes platform to evaluate the items of the protocol. Validation in the clinical context occurred at the University Hospital Onofre Lopes, in Natal/RN with four judges (nurses), who worked in pairs, evaluating 32 patients with venous ulcers. The protocol was validated with 15 categories: sociodemographic data; anamnesis; examinations; ulcer characteristics; care with the lesion and perilesional area; medicines used to treat the lesion; evaluation and treatment of pain; surgical treatment of chronic venous disease; recurrence prevention (clinical and educational strategies); reference; counter-reference; and quality of life.

Conclusion: The validated protocol regarding content and clinical context was applicable. Its implementation is a viable measure that assists in the reorientation of the team in high complexity services, aiming at wound healing and restoration of the patient´s integral health.

HOW REGULATION AFFECTS THE RELEVANCE OF BANK-DEBT MATURITY AS A CONTROL MECHANISM IN DEVELOPED COUNTRIES
Authors: VALLELADO Eleuterio , SAONA Paolo , SAN MARTÍN Pablo
Published: February 2017

Improvements in transparency at the country level have modified the relevance of bank debt maturity as a control mechanism. The novelty of this research is that we provide empirical evidence that the maturity of bank borrowing is contingent on the characteristics of the regulatory and the institutional setting about corporate governance. The main implication of our paper is that corporate governance rules have greater influence in civil-law countries than in common-law countries in promoting efficiency in the use of bank debt maturity. The value of this paper is that our results confirm that the implementation of similar regulations on transparency across countries with different legal systems favors the alignment of the role played by short-term bank debt in addressing asymmetric information, agency costs, and inefficient liquidation.
INFLUENCE OF SENSORY STIMULI ON BRAND EXPERIENCE, BRAND EQUITY AND PURCHASE INTENTION
Authors: MOREIRA António C. , FORTES Nuno , SANTIAGO Ramiro
Published: February 2017

Sensory stimulation is used by various brands to induce desired behaviours among their customers. Although its effectiveness is recognised in business contexts, little research has been conducted on sensory marketing. In order to contribute to filling this gap, this study sought to build a model that explains how sensory stimulation influences intentions to purchase a brand. Brand experience and brand equity were expected to mediate this relationship. The empirical validation of the model was conducted by carrying out an online survey with a convenience sample of 302 customers of a brand of the catering industry. The data collected were processed using PLS-SEM methodology. The results reveal that sensory stimulation positively influences brand experience and brand equity, which, in turn, have a positive impact on intentions to purchase the brand in question. The relevant contributions that emerged from this study include not only bridging the aforementioned gap in the literature but also offering significant managerial implications.
EFFECT OF EXPORT PROMOTION PROGRAMS ON EXPORT PERFORMANCE: EVIDENCE FROM MANUFACTURING SMES
Authors: WANG Xiaoting , CHEN Aihua , WANG Huafeng , LI Shengxiao
Published: February 2017

The objective of this paper is to examine how a firm’s participation in government export promotion programs (epps) may lead to a better export performance. Based on dynamic capabilities perspective, a mediated moderation model of epps on export performance was proposed and tested in Chinese manufacturing smes. The results show marketing implementation capabilities mediate the effect of information-related programs on export performance, and the financial aid-related epps moderate the process. The results contribute to the studies relating epps and export performance, as the results confirm the instrumental role of epps in enhancing export performance and examine the interplay between different types of epps. This study provides a guideline for managers as to how they can benefit from government epps. The findings also imply that policy makers should develop epps with a specific emphasis rather than a general goal of export performance. This study develops new insights on how export ventures exploit epps to develop useful capabilities. Also, the study expands current thinking on exporting by recognizing that different types of epps affect exporting.

Published: February 2017

One of the important activities of a company that can increase its competitiveness is market segment evaluation and selection (mse/mss). We can usually consider mse/mss as a multi-criteria decision-making (mcdm) problem, and so we need to use an mcdm method to handle it. Uncertainty is one of the important factors that can affect the process of decision-making. Fuzzy mcdm approached have been designed to deal with the uncertainty of decision-making problems. In this study, a fuzzy extension of the codas (combinative distance-based assessment) method is proposed to solve multi-criteria group decision-making problems. We use linguistic variables and trapezoidal fuzzy numbers to extend the codas method. The proposed fuzzy codas method is applied to an example of market segment evaluation and selection problem under uncertainty. To validate the results, a comparison is performed between the fuzzy codas and two other mcdm methods (fuzzy edas and fuzzy topsis). A sensitivity analysis is also carried out to demonstrate the stability of the results of the fuzz codas. For this aim, ten sets of criteria weights are randomly generated and the example is solved using each set separately. The results of the comparison and the sensitivity analysis show that the proposed fuzzy codas method gives valid and stable results.

Effects of Magnetic and Kinetic Helicities on the Growth of Magnetic Fields in Laminar and Turbulent Flows by Helical Fourier Decomposition
Authors: Linkmann Moritz , Sahoo Ganapati , McKay Mairi , Berera Arjun , Biferale Luca
Published: February 2017

We present a numerical and analytical study of incompressible homogeneous conducting fluids using a helical Fourier representation. We analytically study both small- and large-scale dynamo properties, as well as the inverse cascade of magnetic helicity, in the most general minimal subset of interacting velocity and magnetic fields on a closed Fourier triad. We mainly focus on the dependency of magnetic field growth as a function of the distribution of kinetic and magnetic helicities among the three interacting wavenumbers. By combining direct numerical simulations of the full magnetohydrodynamics equations with the helical Fourier decomposition, we numerically confirm that in the kinematic dynamo regime the system develops a large-scale magnetic helicity with opposite sign compared to the small-scale kinetic helicity, a sort of triad-by-triad α-effect in Fourier space. Concerning the small-scale perturbations, we predict theoretically and confirm numerically that the largest instability is achived for the magnetic component with the same helicity of the flow, in agreement with the Stretch–Twist–Fold mechanism. Vice versa, in the presence of Lorentz feedback on the velocity, we find that the inverse cascade of magnetic helicity is mostly local if magnetic and kinetic helicities have opposite signs, while it is more nonlocal and more intense if they have the same sign, as predicted by the analytical approach. Our analytical and numerical results further demonstrate the potential of the helical Fourier decomposition to elucidate the entangled dynamics of magnetic and kinetic helicities both in fully developed turbulence and in laminar flows.

We present the second Swift Ultra-Violet/Optical Telescope (UVOT) gamma-ray burst (GRB) afterglow catalog, greatly expanding on the first Swift UVOT GRB afterglow catalog. The second catalog is constructed from a database containing over 120,000 independent UVOT observations of 538 GRBs first detected by Swift, the High Energy Transient Explorer 2 (HETE2), the INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL), the Interplanetary Network (IPN), Fermi, and Astro-rivelatore Gamma a Immagini Leggero (AGILE). The catalog covers GRBs discovered from 2005 January 17 to 2010 December 25. Using photometric information in three UV bands, three optical bands, and a “white” or open filter, the data are optimally coadded to maximize the number of detections and normalized to one band to provide a detailed light curve. The catalog provides positional, temporal, and photometric information for each burst, as well as Swift Burst Alert Telescope and X-ray Telescope (XRT) GRB parameters. Temporal slopes are provided for each UVOT filter. The temporal slope per filter of almost half the GRBs are fit with a single power law, but one to three breaks are required in the remaining bursts. Morphological comparisons with the X-ray reveal that

of the UVOT light curves are similar to one of the four morphologies identified by Evans et al. (2009). The remaining

have a newly identified morphology. For many bursts, redshift- and extinction-corrected UV/optical spectral slopes are also provided at 2 × 103, 2 × 104, and 2 × 105 s.
“Dancing with apocalypse”: The impacts of climate change on livelihood of Tuvalu - Polynesia / “Dançando com o apocalypse”: Os impactos das mudanças climáticas para subsistência em Tuvalu - Polinésia
Authors: Alam Meredian
Published: February 2017

For community living in Least Developing Countries (LDC) climate change has imposed recent pressure on the locals. The impact it causes is also exacerbated by the inadequate infrastructure and regional policy in those countries. With the focus of interest in the case of Tuvalu, one of LDCs located in Western Oceania which clearly encounters rapid destruction due to climatic events, this paper presents the natural changes and living conditions of Tuvaluan inhabitants. Those calamities are caused predominantly by sea-level rise, warmer temperatures, unprecedented cyclones and contaminated water. Benchmarked with other small islands stretching across the Pacific Ocean, the finding demonstrates that Tuvalu has ignoredinternational concerns due to its critical situations that are causedby the government and local community members.
Gentoo Linux for Neuroscience - a replicable, flexible, scalable, rolling-release environment that provides direct access to development software
Authors: Ioanas Horea-Ioan , Saab Bechara , Rudin Markus
Published: February 2017

Gentoo is a GNU/Linux metadistribution designed to maximize and simplify user control of the software environment. All determinants of a Gentoo environment are recorded in a small number of plain-text configuration files, from which the software make-up of the system can be reconstructed entirely. As such, Gentoo constitutes a replicable and transparent software infrastructure - as mandated by research valuing reproducibility. Of equal scientific interest is the flexibility of Gentoo's package management. All software is distributed in a rolling-release fashion, giving the user full control over which versions (including live versions and branches/tags from version control) of which programs to install, and with which compilation options. All of the above is accompanied by automatic, version-aware dependency resolution, which also tracks static library linking and prompts for rebuilds as necessary.

We believe Gentoo is excellently suited to address many of the challenges in neuroscience software management; including: system replicability, system documentation, data analysis reproducibility, fine-grained dependency management, easy control over compilation options, and seamless access to cutting-edge software releases.

We have made a substantial set of neuroimaging and data analysis packages - including their entire dependency stacks - available for any system using Gentoo's Package Management Standard. Neuroscientific software now usable under Gentoo includes but is not limited to:

Dipy (Garyfallidis et al. 2014)

FSL (Jenkinson et al. 2012)

Nipype (Gorgolewski et al. 2016)

Nilearn (Abraham et al. 2014)

PsychoPy (Peirce 2008)

Herein we describe the implementation and current capabilities of this environment, as well as its ability to accelerate and improve research.
A Novel MK-based Geopolymer Composite Activated with Rice Husk Ash and KOH: Performance at High Temperature

Published: February 2017

Geopolymers were produced using an environmentally friendly alkali activator (based on Rice Husk Ash and potassium hydroxide). Aluminosilicates particles, carbon and ceramic fibres were used as reinforcement materials. The effects of reinforcement materials on the flexural strength, linear-shrinkage, thermophysical properties and microstructure of the geopolymers at room and high temperature (1200 ÅãC) were studied. The results indicated that the toughness of the composites is increased 110.4% for geopolymer reinforced by ceramic fibres (G-AF) at room temperature. The presence of particles improved the flexural behaviour 265% for geopolymer reinforced by carbon fibres and particles after exposure to 1200 .C. Linear-shrinkage for geopolymer reinforced by ceramic fibres and particles and the geopolymer G-AF compared with reference sample (without fibres and particles) is improved by 27.88% and 7.88% respectively at 900 ÅãC. The geopolymer materials developed in this work are porous materials with low thermal conductivity and good mechanical properties with potential thermal insulation applications for building applications.
Alarmins: Feel the Stress

Published: February 2017

Over the last decade, danger-associated molecular pattern molecules, or alarmins, have been recognized as signaling mediators of sterile inflammatory responses after trauma and injury. In contrast with the accepted passive release models suggested by the “danger hypothesis,” it was recently shown that alarmins can also directly sense and report damage by signaling to the environment when released from live cells undergoing physiological stress, even without loss of subcellular compartmentalization. In this article, we review the involvement of alarmins such as IL-1α, IL-33, IL-16, and high-mobility group box 1 in cellular and physiological stress, and suggest a novel activity of these molecules as central initiators of sterile inflammation in response to nonlethal stress, a function we denote “stressorins.” We highlight the role of posttranslational modifications of stressorins as key regulators of their activity and propose that targeted inhibition of stressorins or their modifiers could serve as attractive new anti-inflammatory treatments for a broad range of diseases.
Spontaneous Thyroid Hemorrhage on Chronic Anticoagulation Therapy

Published: February 2017

Even though highly vascularized, the thyroid gland rarely has spontaneous bleeding. Bleeding into the thyroid gland can result in potentially lethal acute airway compromise. This case report describes an elderly patient on warfarin for atrial fibrillation, who presented with swelling on the right side of her neck causing acute airway obstruction. An urgent computed tomography of the neck showed an enlarging hemorrhage into the right lobe of the thyroid gland. She was initially intubated for airway protection and her anticoagulation was reversed to stop the bleeding. She was closely monitored in the intensive care unit. After an uncomplicated tracheal extubation and recovery, she was discharged and scheduled for an elective total thyroidectomy. We desire that physicians be aware of this rare, potentially lethal bleeding complication.
Reinstatement and Specificty in Argumentation Systems
Authors: Alessio Claudio Andres
Published: February 2017

Reinstatement is a principle of argumentation systems that enables the justification of a defeated argument when all its defeaters are in turn ultimately defeated. Some counterexamples to reinstatement have been offered in the literature. Specifically, counterexamples suggest that reinstatement cannot be taken as a general principle of defeasible argumentation because the reinstated arguments may support incorrect conclusions. Some authors argued that the problems are not due to reinstatement but to the formalization of those examples. Then, the solution is to make the language expressive enough to obtain the correct results. They also warn that one should avoid tinkering with the formalization in concrete examples just to get a desired outcome. Therefore, this approach should be combined with the search of general principles for choosing the proper formalization. Taking into account that finding general principles of representation could be a hard enterprise, the goal of this thesis is to identify some criterion that allows i. neutralize the counterexamples, ii. preserve the original formal language as much as possible, and iii. maintain reinstatement as a general principle. To identify that criterion, counterexamples are analyzed and possible causes of the problem are detected. As a result it is found that the preference by specificity among arguments can be used to obtain that criterion. Three approaches based on specificity are proposed and evaluated. Two of them introduce alternative defeat relations among arguments. The third one is based on filtering the non maximally specific arguments.
