Influence of Reclaimed Asphalt Pavement on Performance-Related Properties of Gap-Graded Rubberized Hot-Mix Asphalt
Authors: Hung Shawn S. , Alavi Mohammad Zia , Jones David , Harvey John T.
Published: October 2017

Rubberized hot-mix asphalt (RHMA) has been widely used in construction projects by the California Department of Transportation (Caltrans) for the environmental benefits of its recycled waste tires and for its improved fatigue and reflective cracking resistance. Currently, Caltrans does not permit the use of reclaimed asphalt pavement (RAP) in any gap- or open-graded rubberized asphalt mixes. However, given the cost and environmental benefits of RAP to replace portions of required virgin binder and aggregates in conventional mixes, interest is growing in the addition of some RAP to RHMA mixes as well. This study investigated concerns about this proposed practice. Three phases of laboratory testing (i.e., asphalt binder testing, fine aggregate matrix mix testing, and full-graded mix testing) were conducted to evaluate the effects of the addition of RAP into new RHMA mixes. The results indicated that the gap-graded aggregate structure of RHMA might limit the amount of RAP that could be used in the mix. Only 10% RAP by binder replacement could be achieved for the mix tested in this study, but the other specified volumetric requirements were still met. Replacement of a portion of asphalt rubber binder with age-hardened RAP binder increased the binder stiffness at low and high temperatures, which indicated enhanced rutting performance but diminished low-temperature cracking performance. Test results from full-graded mixes indicated similar trends, with improved rutting performance with the addition of RAP but also with significantly poorer fatigue and reflective cracking resistance.

Published: October 2017

This paper presents the findings of a research study to determine the benefits of fiber-reinforced asphalt mixtures used to mitigate distresses observed in the field. Control asphalt mixture test sections were constructed on US-30 in Idaho, along with fiber-reinforced asphalt mixture test sections. Three types of fibers were evaluated: Fiber 1 (i.e., aramid and polyolefin fiber), Fiber 2 (i.e., wax-treated aramid fiber), and Fiber 3 (i.e., glass fiber). Several laboratory tests were conducted on laboratory-prepared test samples and extracted field cores. The laboratory tests included dynamic modulus, flow number, Hamburg wheel-track test, indirect tensile test, creep compliance, and semicircular bending, in addition to performance evaluation with AASHTOWare Pavement ME Design software. The laboratory results showed no significant improvement to the properties of asphalt mixtures at the fiber content recommended by the manufacturer. However, the performance of asphalt mixtures did improve at a fiber dosage higher than the one recommended by the manufacturer. This study demonstrated the need to evaluate different fiber contents when asphalt mixtures are designed, because the dosage recommended by the manufacturer may not be optimal for various asphalt mixtures.
Toward the Design of an Induction Heating System for Asphalt Pavements with the Finite Element Method
Authors: Apostolidis Panos , Liu Xueyan , Kasbergen Cor , Scarpas A.Tom , van de Ven Martinus
Published: October 2017

Induction technology was introduced to the paving industry to assist pavement operations by heating asphalt layers efficiently from the surface. Many experimental studies have been conducted to investigate the impact of inductive particles on the heating efficiency of asphalt mixes. However, research is limited on the quantification of design, the operational factors, and the associated degree of heat generation of induction treatment. This study assessed the hypothesis that different systems of induction coils provoke different levels of heat generation within an inductive asphalt layer. First, a three-dimensional induction heating finite element model was developed to evaluate the design and effect of operational factors for a static single-turn induction coil system. The electrical conductivity values of the material in the inductive asphalt pavement were calibrated with a laboratory-scale induction device. Moving induction systems were analyzed with different operational conditions considered. The supplied power and the traveling speed of the induction system appeared to be the most influential operational factors for the development of a quick and highly efficient system. The developed model creates an opportunity to apply these analyses to asphalt pavements to optimize the technology in situ.
Embodied Vibrations
Authors: Adams-Hutcheson Gail
Published: October 2017

This article contributes to debates that consider things (buildings) that have
previously been assumed to be bounded and fixed. When thinking about how
literally anything can become mobile, this article addresses how buildings “live
on” through the bodies of participants. The notion of material affects is advanced
to draw together a complex set of ideas on vibrant materialities. Material
affects, then, entangle the earth, forces, embodiment, and micro mobilities
to expose the vibrant matter of buildings. Empirical material is drawn from
semistructured interviews with people who relocated out of Christchurch following
the 2010 and 2011 earthquakes and aftershocks. In relocation, acute
spatial awareness and sensitivity to movement and vibration—that is, the minute
shudders and flexes of buildings—colonized the bodies of participants.
Material affects are able to challenge the distinction between vital energy (life)
forces and materiality.

Providing Laboratory Rutting Models for Modified Asphalt Mixes with Different Waste Materials
Authors: Azarhoosh Ali Reza , Hamedi Gholam Hossein , Abandansari Hossein Fallahi
Published: October 2017

Due to the complex behavior of asphalt pavement materials under various loading conditions, pavement structure, and environmental conditions, accurately predicting the permanent deformation of asphalt pavement is difficult. This study discusses the application of artificial neural network (ANN) and the multiple linear regression (MLR) in predicting permanent deformation of asphalt concrete mixtures modified by waste materials (waste plastic bottles and waste high-density polyethylene). The use of waste materials in the pavement industry can prevent the accumulation of waste material and environmental pollution and can reduce primary production costs. The results of a laboratory study evaluating the rutting properties of Hot-Mix Asphalt (HMA) mixtures using dynamic creep tests were investigated. The results indicate ANN techniques are more effective in predicting the rutting of the modified mixtures tested in this study than the traditional statistical-based prediction models. On the other hand, results show that an increase in percentage of waste materials is very effective in reducing the final strain of asphalt mixtures. However, an increase in percentage of additives over 7% does not help to reduce permanent deformation under dynamic loading in the asphalt mixtures.
Challenges for Annotation Concepts in Music
Authors: Hadjakos Aristotelis , Iffland Joachim , Keil Reinhard , Oberhoff Andreas , Veit Joachim
Published: October 2017

Traditional historico-critical music editions provide scholars and musicians with an edited score based on the interpretation of various sources such as the composer's autograph(s), letters and other materials from copyists or publishers. Their digital counterparts have the potential to offer new and more expanded ways to explore the work. This is based on the possibility to provide large amounts of source materials and to annotate more extensively (since printing costs are irrelevant). Furthermore, audio and video recordings of performances can be integrated. But, similarly important, the user interface makes it much easier to navigate in the complex network of cross-references between various source materials and the editor's annotations. The XML-based Music Encoding Initiative (MEI) format is the standard music representation format for digital music editions. In this article we discuss current MEI-based annotation practices and outline the current challenges for music annotations, including a discussion of anchoring options, the embedding of addressable elements in the local musical context, the annotation of audio, and the categorisation of annotations. This leads to a discussion of open questions such as the ability to secure authorship in open and reusable editions.
Practical Linguistic Annotation: The Hebrew Bible
Authors: Roorda Dirk
Published: October 2017

Annotation and research in the humanities are tightly coupled. Annotations can be seen as expressions of research activity which can be turned into input data for subsequent research. The digital paradigm has profoundly altered the ways in which we humans can handle the information content of our sources and it also affects the practice of annotation. We explore new ways of annotation that were not feasible before the digital times, and we list a few requirements for annotation to act as a reliable source of research information. Rather than conducting an academic discussion on the ontology of annotations, we highlight practical use cases for new kinds of annotations. We illustrate those in a concrete system for linguistic annotations to the Hebrew Bible, SHEBANQ.
Downdraft Assessment of Glass Curtain Wall Buildings with a Radiant Floor Heating System

Published: October 2017

The present study aims to evaluate whether downdraft can be prevented by applying a radiant floor heating system in glass curtain wall buildings. A radiant floor heating system does not directly supply heat to cold air, but does so via heat exchange with a cold airflow. Assessing whether a downdraft is prevented is, thus, necessary. For this assessment, a radiant floor heating system was applied to perimeter zones with different window types modeled using a computational fluid dynamics (CFD) simulation. The relationship between the radiant floor heating system and the windows was examined via an assessment of the resulting downdraft by considering the radiant heat exchange effect between the window and the floor. The assessment was conducted by utilizing a CFD simulation. The simulation results show that the temperature difference between the air supplied through the radiant floor heating system and the air descending along the cold surface of the window increased when the radiant floor heating system was applied to a narrow area with a high temperature. Furthermore, the airflow velocity increased with the heat exchange. The airflow re-entered the window side, and the downdraft in the occupied area exceeded the strict value specified by the standards. Conversely, if heat were applied according to the indoor thermal output by widening the radiant heat area of the radiant floor heating system, a downdraft could occur as a result of a blocking failure prior to the influx of the cold air into the occupied area caused by low surface temperatures. Therefore, applying a radiant floor heating system is advantageous in a perimeter zone without causing airflow inducement at the window side with acceptable surface temperatures.
Profiling the Fatty Acids Content of Ornamental Camellia Seeds Cultivated in Galicia by an Optimized Matrix Solid-Phase Dispersion Extraction
Authors: Garcia-Jares Carmen , Sanchez-Nande Marta , Lamas Juan , Lores Marta
Published: October 2017

Camellia (genus of flowering plants of fam. Theaceae) is one of the main crops in Asia, where tea and oil from leaves and seeds have been utilized for thousands of years. This plant is excellently adapted to the climate and soil of Galicia (northwestern Spain) and northern Portugal where it is grown not only as an ornamental plant, but to be evaluated as a source of bioactive compounds. In this work, the main fatty acids were extracted from Camellia seeds of four varieties of Camellia: sasanqua, reticulata, japonica and sinensis, by means of matrix-solid phase dispersion (MSPD), and analyzed by gas chromatography (GC) with MS detection of the corresponding methyl esters. MSPD constitutes an efficient and greener alternative to conventional extraction techniques, moreover if it is combined with the use of green solvents such as limonene. The optimization of the MSPD extraction procedure has been conducted using a multivariate approach based on strategies of experimental design, which enabled the simultaneous evaluation of the factors influencing the extraction efficiency as well as interactions between factors. The optimized method was applied to characterize the fatty acids profiles of four Camellia varieties seeds, allowing us to compare their fatty acid composition.

A Novel Probabilistic Optimal Power Flow Method to Handle Large Fluctuations of Stochastic Variables
Authors: Deng Xiaoyang , He Jinghan , Zhang Pei
Published: October 2017

The traditional cumulant method (CM) for probabilistic optimal power flow (P-OPF) needs to perform linearization on the Karush–Kuhn–Tucker (KKT) first-order conditions, therefore requiring input variables (wind power or loads) varying within small ranges. To handle large fluctuations resulting from large-scale wind power and loads, a novel P-OPF method is proposed, where the correlations among input variables are also taken into account. Firstly, the inverse Nataf transformation and Cholesky decomposition are used to obtain samples of wind speeds and loads with a given correlation matrix. Then, the K-means algorithm is introduced to group the samples of wind power outputs and loads into a number of clusters, so that in each cluster samples of stochastic variables have small variances. In each cluster, the CM for P-OPF is conducted to obtain the cumulants of system variables. According to these cumulants, the moments of system variables corresponding to each cluster are computed. The moments of system variables for the total samples are obtained by combining the moments for all grouped clusters through the total probability formula. Then, the moments for the total samples are used to calculate the corresponding cumulants. Finally, Cornish–Fisher expansion is introduced to obtain the probability density functions (PDFs) of system variables. IEEE 9-bus and 118-bus test systems are modified to examine the proposed method. Study results show that the proposed method can produce more accurate results than traditional CM for P-OPF and is more efficient than Monte Carlo simulation (MCS).
Experimental Evaluation of the Thermal Performance of Raised Floor Integrated Radiant Heating Panels
Authors: Kim Dong-Woo , Joe Goo-Sang , Park Sang-Hoon , Yeo Myoung-Souk , Kim Kwang-Woo
Published: October 2017

In this study, we propose a method for the evaluation of the thermal output of radiant heating panels by employing a modification of the currently used method, which is recommended by existing standards, using cooling plates. We aim to overcome the absence in the measurement method of the downward thermal output as well as to address the challenges in the control of the heat transfer resistance of the heat transfer layer, which arise due to the contact resistance between the layers. Using the modified method, we compare the thermal performance of three types of raised floor integrated radiant heating panels that have different filler materials for the bottom insulation of the panel. We show that the most efficient sample panel is the one that is not filled with a material; with an efficiency of 70.1%. In addition, we show that the value of the gradient of the characteristic curve calculated by the existing method ranged between 7.2% to 14.9% larger than that obtained by modified method. This difference is attributed to the heat transfer resistance of the heat transfer layer that is present in the experiments, and has a value in the interval of 0.1096 m 2 K / W to 0.1582 m 2 K / W . This is caused by the contact resistance between the heat transfer layer and other layers, even though the heat transfer resistance of the heat transfer layer used in the experiment is 0.0985 m 2 K / W . The modified method proposed in this study reveals that the experimental results are not influenced by the heat transfer resistance of the heat transfer layer. We also show that our experimental results are reproducible.
IAACaaS: IoT Application-Scoped Access Control as a Service
Authors: Alonso Álvaro , Fernández Federico , Marco Lourdes , Salvachúa Joaquín
Published: October 2017

access control is a key element when guaranteeing the security of online services. However, devices that make the Internet of Things have some special requirements that foster new approaches to access control mechanisms. Their low computing capabilities impose limitations that make traditional paradigms not directly applicable to sensors and actuators. In this paper, we propose a dynamic, scalable, IoT-ready model that is based on the OAuth 2.0 protocol and that allows the complete delegation of authorization, so that an as a service access control mechanism is provided. Multiple tenants are also supported by means of application-scoped authorization policies, whose roles and permissions are fine-grained enough to provide the desired flexibility of configuration. Besides, OAuth 2.0 ensures interoperability with the rest of the Internet, yet preserving the computing constraints of IoT devices, because its tokens provide all the necessary information to perform authorization. The proposed model has been fully implemented in an open-source solution and also deeply validated in the scope of FIWARE, a European project with thousands of users, the goal of which is to provide a framework for developing smart applications and services for the future Internet. We provide the details of the deployed infrastructure and offer the analysis of a sample smart city setup that takes advantage of the model. We conclude that the proposed solution enables a new access control as a service paradigm that satisfies the special requirements of IoT devices in terms of performance, scalability and interoperability.
Housing and Health of Kiribati Migrants Living in New Zealand
Authors: Teariki Mary
Published: October 2017

Settlement is a complex process of adjustment for migrants and refugees. Drawing on recent research on the settlement experiences of Kiribati migrants and their families living in New Zealand, this article examines the role of housing as an influencer of the settlement and health of Kiribati migrants. Using qualitative methodology, in-depth interviews were conducted with fourteen Kiribati migrants (eight women and six men) representing 91 family members about the key issues and events that shaped their settlement in New Zealand. The stories told by participants affirm the association between housing and health. The study serves as an important reminder that children bear a great cost from living in poorly insulated and damp housing, and adults bear the mental costs, including social isolation resulting from inadequate rental housing. Detailed information about how this migrant group entered the private rental housing market, by taking over the rental leases of other Kiribati migrants vacating their rental properties, indicated some of the unintended consequences related to a lack of incentives for landlords to make improvements. With the most vulnerable families most at risk from inadequate housing, this research concludes that there is a need for minimum housing standards to protect tenants.

Antibacterial and Tribological Performance of Carbonitride Coatings Doped with W, Ti, Zr, or Cr Deposited on AISI 316L Stainless Steel
Authors: Yao Sun-Hui , Su Yen-Liang , Lai Yu-Cheng
Published: October 2017

Carbonitride (CNx) coatings have existed for several decades but are not well understood. Related studies have indicated that CNx coatings exhibit behaviors comparable to diamond-like carbon (DLC) coatings. Metal-doped CNx coatings are expected to show superior performance to single CNx coatings. In this study, a CNx coating and a group of CNx coatings with 6 at. % metal doping (W, Ti, Zr, or Cr) were prepared on biograde AISI 316L stainless steel (SS316L) substrates, and they were then characterized and studied for antibacterial and wear performance. The microstructure, constituent phase, nanohardness, adhesion, surface roughness, and contact angle were evaluated. The antimicrobial test used Staphylococcus aureus and followed the Japanese Industrial Standard JIS Z 2801:2010. Finally, the wear behavior was assessed. The results showed that the CNx coating was a composite of amorphous CNx and amorphous C structures. The metal doping caused crystalline metal carbides/nitrides to form in the CNx coatings, which weakened their overall integrity. All the coatings showed antimicrobial ability for the SS316L samples. The CNx-Zr coating, the surface of which had the highest hydrophilicity, produced the best antibacterial performance. However, the CNx-Zr coating showed lower wear resistance than the CNx-W and CNx-Ti coatings. The CNx-Ti coating with a highly hydrophilic surface exhibited the lowest antibacterial ability.
The Role of Self-Interaction Corrections, Vibrations, and Spin-Orbit in Determining the Ground Spin State in a Simple Heme
Authors: Kao Der-you , Pederson Mark , Hahn Torsten , Baruah Tunna , Liebing Simon , Kortus Jens
Published: October 2017

Without self-interaction corrections or the use of hybrid functionals, approximations to the density-functional theory (DFT) often favor intermediate spin systems over high-spin systems. In this paper, we apply the recently proposed Fermi–Löwdin-orbital self-interaction corrected density functional formalism to a simple tetra-coordinated Fe(II)-porphyrin molecule and show that the energetic orderings of the S = 1 and S = 2 spin states are changed qualitatively relative to the results of Generalized Gradient Approximation (developed by Perdew, Burke, and Ernzerhof, PBE-GGA) and Local Density Approximation (developed by Perdew and Wang, PW92-LDA). Because the energetics, associated with changes in total spin, are small, we have also calculated the second-order spin–orbit energies and the zero-point vibrational energies to determine whether such corrections could be important in metal-substituted porphins. Our results find that the size of the spin–orbit and vibrational corrections to the energy orderings are small compared to the changes due to the self-interaction correction. Spin dependencies in the Infrared (IR)/Raman spectra and the zero-field splittings are provided as a possible means for identifying the spin in porphyrins containing Fe(II).

Chiral N-protected α-amino aryl-ketones are one of the useful precursors used in the synthesis of various biologically active compounds and can be constructed via Friedel–Crafts acylation of N-protected α-amino acids. One of the drawbacks of this reaction is the utilization of toxic, corrosive and moisture-sensitive acylating reagents. In peptide construction via amide bond formation, N-hydroxysuccinimide ester (OSu), which has high storage stability, can react rapidly with amino components and produces fewer side reactions, including racemization. This study reports the first synthesis and utilization of N-trifluoroacetyl (TFA)-protected α-amino acid-OSu as a potential acyl donor for Friedel–Crafts acylation into various arenes. The TFA-protected isoleucine derivative and its diastereomer TFA-protected allo-isoleucine derivative were investigated to check the retention of α-proton chirality in the Friedel–Crafts reaction. Further utilization of OSu in other branched-chain and unbranched-chain amino acids results in an adequate yield of TFA-protected α-amino aryl-ketone without loss of optical purity.

Alternative Opportunistic Alert Diffusion to Support Infrastructure Failure during Disasters
Authors: Mezghani Farouk , Mitton Nathalie
Published: October 2017

Opportunistic communications present a promising solution for disaster network recovery in emergency situations such as hurricanes, earthquakes, and floods, where infrastructure might be destroyed. Some recent works in the literature have proposed opportunistic-based disaster recovery solutions, but they have omitted the consideration of mobile devices that come with different network technologies and various initial energy levels. This work presents COPE, an energy-aware Cooperative OPportunistic alErt diffusion scheme for trapped survivors to use during disaster scenarios to report their position and ease their rescue operation. It aims to maintain mobile devices functional for as long as possible for maximum network coverage until reaching proximate rescuers. COPE deals with mobile devices that come with an assortment of networks and aims to perform systematic network interface selection. Furthermore, it considers mobile devices with various energy levels and allows low-energy nodes to hold their charge for longer time with the support of high-energy nodes. A proof-of-concept implementation has been performed to study the doability and efficiency of COPE, and to highlight the lessons learned.
Separation and Purification with a Liquid Stationary Phase
Authors: Berthod Alain
Published: October 2017

Yoichiro Ito introduced countercurrent chromatography (CCC) in 1966, reporting the separation of blood plasma cells with a sealed helical tube. Since then, CCC has been a fertile ground for instrumental and technical innovation. The key innovation of CCC was to use centrifugal forces to retain the stationary liquid phase in the column in such a way that it is able to interact dynamically with the mobile phase without any solid support. The broad diversity of countercurrent separation terminology reflects the innovative spirit of the field, as well as the global appeal of this technique. The selection of the appropriate biphasic liquid system is the core of the CCC technique. The CCC columns must generate the centrifugal field needed to maintain the liquid stationary phase; therefore, they cannot be a simple tube with frits at both ends. Rotors, motor, gears, spools, and rotating seals are very specific things that are not needed in a classical liquid chromatography column with a solid stationary phase. The differences between the two main types of CCC columns are described. The bases of the CCC theory are also given.
Channels to West: Exploring the Migration Routes between Romania and France
Authors: Matichescu Marius , Dragan Alexandru , Lucheș Daniel
Published: October 2017

The integration of East European Countries in European Union has long-term consequences, with migration being one of the main social effects of this process. From an economic perspective, the research on migration has attracted considerable attention, whereas the analyses focused on the social networks are more scarce. The importance of these social networks becomes more substantial due to their quality and ability to reduce costs, risks of movement and uncertainty. Although the migratory networks are known at national levels, there are very few data related to the territorial distribution of migration network between origin and destination areas. In this context, Romania registered the highest level of emigration toward Western European countries, and this case study offers illustrative insights for the broader literature. In order to illustrate the territorial distribution of migrants’ network between Romania and France, we used an exhaustive analysis of the trajectories of all clients who used one of the largest transport companies operating between Romania and France (8094 cases). Using the benefits of this evidence-based approach, we identified the regions and the Romanian towns most affected by the migration phenomenon. Complementary, we illustrated the territorial distribution and the preferred destination regions in France for the Romanian immigrants. We present the migration networks that exist between the towns of the two countries and identify the intensity of each migration circuit.
Multiple Signal Classification Algorithm Based Electric Dipole Source Localization Method in an Underwater Environment
Authors: Xu Yidong , Xue Wei , Li Yingsong , Guo Lili , Shang Wenjing
Published: October 2017

A novel localization method based on multiple signal classification (MUSIC) algorithm is proposed for positioning an electric dipole source in a confined underwater environment by using electric dipole-receiving antenna array. In this method, the boundary element method (BEM) is introduced to analyze the boundary of the confined region by use of a matrix equation. The voltage of each dipole pair is used as spatial-temporal localization data, and it does not need to obtain the field component in each direction compared with the conventional fields based localization method, which can be easily implemented in practical engineering applications. Then, a global-multiple region-conjugate gradient (CG) hybrid search method is used to reduce the computation burden and to improve the operation speed. Two localization simulation models and a physical experiment are conducted. Both the simulation results and physical experiment result provide accurate positioning performance, with the help to verify the effectiveness of the proposed localization method in underwater environments.

The frontier of data discoverability: Why we need to share our data1
Authors: Culley Theresa M.
Published: October 2017

We are now in an era where sharing and making data widely accessible are not only expected within many disciplines, but also required by federal granting agencies and many scientific journals. In addition, there are practical reasons why authors should deposit their data into permanent data repositories: (1) it prevents data loss due to accidents, theft, or death of the researcher; (2) it enables published research to be reproduced by others; (3) publications associated with accessible data sets can have higher citation rates; (4) deposited data sets are increasingly recognized for scholarly recognition and professional advancement; and (5) stored and accessible data can be used in the future for projects that are unanticipated today. Applications in Plant Sciences requires that data underlying its articles be publicly accessible as a condition of publication to promote the continued advancement of the field of plant biology.

Titania-supported palladium, gold and bimetallic nanoparticles (second-generation nanoparticles) demonstrate promising photocatalytic properties. However, due to unusual reactivity, second-generation nanoparticles can be hazardous for living organisms. Considering the ever-growing number of new types of nanoparticles that can potentially contaminate the environment, a determination of their toxicity is extremely important. The main aim of presented study was to investigate the cytotoxic effect of surface modified TiO2-based nanoparticles, to model their quantitative nanostructure–toxicity relationships and to reveal the toxicity mechanism. In this context, toxicity tests for surface-modified TiO2-based nanoparticles were performed in vitro, using Gram-negative bacteria Escherichia coli and Chinese hamster ovary (CHO-K1) cells. The obtained cytotoxicity data were analyzed by means of computational methods (quantitative structure–activity relationships, QSAR approach). Based on a combined experimental and computational approach, predictive models were developed, and relationships between cytotoxicity, size, and specific surface area (Brunauer–Emmett–Teller surface, BET) of nanoparticles were discussed.
NIR-driven Moist Upper Atmospheres of Synchronously Rotating Temperate Terrestrial Exoplanets
Authors: Fujii Yuka , Del Genio Anthony D. , Amundsen David S.
Published: October 2017

H2O is a key molecule in characterizing atmospheres of temperate terrestrial planets, and observations of transmission spectra are expected to play a primary role in detecting its signatures in the near future. The detectability of H2O absorption features in transmission spectra depends on the abundance of water vapor in the upper part of the atmosphere. We study the three-dimensional distribution of atmospheric H2O for synchronously rotating Earth-sized aquaplanets using the general circulation model (GCM) ROCKE-3D, and examine the effects of total incident flux and stellar spectral type. We observe a more gentle increase of the water vapor mixing ratio in response to increased incident flux than one-dimensional models suggest, in qualitative agreement with the climate-stabilizing effect of clouds around the substellar point previously observed in GCMs applied to synchronously rotating planets. However, the water vapor mixing ratio in the upper atmosphere starts to increase while the surface temperature is still moderate. This is explained by the circulation in the upper atmosphere being driven by the radiative heating due to absorption by water vapor and cloud particles, causing efficient vertical transport of water vapor. Consistently, the water vapor mixing ratio is found to be well-correlated with the near-infrared portion of the incident flux. We also simulate transmission spectra based on the GCM outputs, and show that for the more highly irradiated planets, the H2O signatures may be strengthened by a factor of a few, loosening the observational demands for a H2O detection.
Apex Dips of Experimental Flux Ropes: Helix or Cusp?
Authors: Wongwaitayakornkul Pakorn , Haw Magnus A. , Li Hui , Li Shengtai , Bellan Paul M.
Published: October 2017

We present a new theory for the presence of apex dips in certain experimental flux ropes. Previously such dips were thought to be projections of a helical loop axis generated by the kink instability. However, new evidence from experiments and simulations suggest that the feature is a 2D cusp rather than a 3D helix. The proposed mechanism for cusp formation is a density pileup region generated by nonlinear interaction of neutral gas cones emitted from fast-gas nozzles. The results indicate that density perturbations can result in large distortions of an erupting flux rope, even in the absence of significant pressure or gravitational forces. The density pileup at the apex also suppresses the m = 1 kink mode by acting as a stationary node. Consequently, more accurate density profiles should be considered when attempting to model the stability and shape of solar and astrophysical flux ropes.

We estimate the current extinction-corrected Hα star formation rate (SFR) of the different morphological components that shape galaxies (bulges, bars, and disks). We use a multicomponent photometric decomposition based on Sloan Digital Sky Survey imaging to Calar Alto Legacy Integral Field Area Integral Field Spectroscopy (IFS) datacubes for a sample of 219 galaxies. This analysis reveals an enhancement of the central SFR and specific SFR (sSFR = SFR/M
⋆) in barred galaxies. Along the main sequence, we find that more massive galaxies in total have undergone efficient suppression (quenching) of their star formation, in agreement with many studies. We discover that more massive disks have had their star formation quenched as well. We evaluate which mechanisms might be responsible for this quenching process. The presence of type 2 AGNs plays a role at damping the sSFR in bulges and less efficiently in disks. Also, the decrease in the sSFR of the disk component becomes more noticeable for stellar masses around

for bulges, it is already present at

. The analysis of the line-of-sight stellar velocity dispersions (σ) for the bulge component and of the corresponding Faber–Jackson relation shows that AGNs tend to have slightly higher σ values than star-forming galaxies for the same mass. Finally, the impact of environment is evaluated by means of the projected galaxy density, Σ5. We find that the SFR of both bulges and disks decreases in intermediate- to high-density environments. This work reflects the potential of combining IFS data with 2D multicomponent decompositions to shed light on the processes that regulate the SFR.
A Tale of Two Impostors: SN2002kg and SN1954J in NGC 2403*

We describe new results on two supernova impostors in NGC 2403, SN 1954J(V12) and SN 2002kg(V37). For the famous object SN 1954J, we combine four critical observations: its current SED, its Hα emission line profile, the Ca ii triplet in absorption in its red spectrum, and the brightness compared to its pre-event state. Together, these strongly suggest that the survivor is now a hot supergiant with T ∼ 20,000 K, a dense wind, substantial circumstellar extinction, and a G-type supergiant companion. The hot star progenitor of V12's giant eruption was likely in the post-red supergiant stage and had already shed a lot of mass. V37 is a classical LBV/S Dor variable. Our photometry and spectra observed during and after its eruption show that its outburst was an apparent transit on the HR Diagram due to enhanced mass loss and the formation of a cooler, dense wind. V37 is an evolved hot supergiant at ≈106

with a probable initial mass of 60–80

Les stratégies d'internationalisation en assurances
Authors: Desombre Nicolas , Duverne Denis , de Montchalin Amélie
Published: October 2017

Les grandes compagnies d’assurance sont confrontées à une multitude de défis qui appellent à une transformation profonde de leurs organisations, leurs ambitions et leurs modes de fonctionnement. Alors que les grands assureurs européens ont été dès le début des années 1980 les pionniers de la dynamique d’internationalisation à travers de nombreuses acquisitions transfrontalières au niveau mondial, l’évolution de leur environnement les contraint à s’interroger sur leur « raison d’être » à l’international. Les stratégies d’internationalisation depuis trente ans sont restées guidées par l’expansion géographique plus que par une convergence entre les produits vendus, réduisant ainsi les économies d’échelle potentielles. La régulation financière et les conditions de marchés, ainsi que les ruptures technologiques, poussent aujourd’hui les compagnies d’assurance à se recentrer sur des marchés stables et offrent de la visibilité économique et politique. Les exigences de rentabilité et de cohérence stratégique sont actuellement fortes et appellent à l’optimisation de la présence internationale plutôt qu’à son expansion foisonnante.

Obligations catastrophes : comment les marchés financiers évaluent-ils les facteurs de risques naturels ?
Authors: Bianchi Milo , Landier Augustin , Zajac Michal
Published: October 2017

Les obligations catastrophes constituent une classe de titres financiers dont les rendements sont liés à la survenance d’événements naturels exceptionnels. En recourant à une nouvelle base de données exclusive, nous examinons les déterminants de la fixation du prix des obligations catastrophes ( cat-bonds ). Nous constatons que les cat-bonds sont des titres à faible bêta : elles sont peu exposées au risque de marché du marché boursier et (bien que dans une moindre mesure) au risque associé aux obligations de société. Leur prime de risque, nettement positive, ne s’explique pas par une exposition au risque systématique. Nous montrons que la réputation de l’émetteur a une incidence sur la tarification : les prix des obligations émises par des émetteurs inexpérimentés sont fixés avec une décote.

Constructing Knowledge-Based Feedback in the Context of an Interactive Spoken CALL Application
Authors: Tsourakis Nikos , Baur Claudia , Rayner Manny
Published: October 2017

Modern Computer Assisted Language Learning (CALL) systems use speech recognition to give students the opportunity to build up their spoken language skills through interactive practice with a mechanical partner. Besides the obvious benefits that these systems can offer, e.g. flexible and inexpensive learning, user interaction in this context can often be problematic. In this article, the authors introduce a parallel layer of feedback in a CALL application, which can monitor interaction, report errors and provide advice and suggestions to students. This mechanism combines knowledge accumulated from four different inputs in order to decide on appropriate feedback, which can be customized and adapted in terms of phrasing, style and language. The authors report the results from experiments conducted at six lower secondary classrooms in German-speaking Switzerland with and without this mechanism. After analyzing approximately 13,000 spoken interactions it can be reasonably argued that their parallel feedback mechanism in L2 actually does help students during interaction and contributes as a motivation factor.
