Characterization of density fluctuations during the search for an I-mode regime on the DIII-D tokamak

The I-mode regime, routinely observed on the Alcator C-Mod tokamak, is characterized by an edge energy transport barrier without an accompanying particle barrier and with broadband instabilities, known as weakly coherent modes (WCM), believed to regulate particle transport at the edge. Recent experiments on the DIII-D tokamak exhibit I-mode characteristics in various physical quantities. These DIII-D plasmas evolve over long periods, lasting several energy confinement times, during which the edge electron temperature slowly evolves towards an H-mode-like profile, while maintaining a typical L-mode edge density profile. During these periods, referred to as I-mode phases, the radial electric field at the edge also gradually reaches values typically observed in H-mode. Density fluctuations measured with the phase contrast imaging diagnostic during I-mode phases exhibit three features typically observed in H-mode on DIII-D, although they develop progressively with time and without a sharp transition: the intensity of the fluctuations is reduced; the frequency spectrum is broadened and becomes non-monotonic; two dimensional space-time spectra appear to approach those in H-mode, showing phase velocities of density fluctuations at the edge increasing to about 10 km s−1. However, in DIII-D there is no clear evidence of the WCM. Preliminary linear gyro-kinetic simulations are performed in the pedestal region with the GS2 code and its recently upgraded model collision operator that conserves particles, energy and momentum. The increased bootstrap current and flow shear generated by the temperature pedestal are shown to decrease growth rates, thus possibly generating a feedback mechanism that progressively stabilizes fluctuations.United States.

Spin-polarized electric current in silicene nanoribbons induced by atomic adsorption

We investigate the nonequilibrium transport properties of a silicene armchair nanoribbon with a random distribution of adsorbed atoms in apex positions. A ferromagnetic insulator grown below the nanoribbon splits spin-up and spin-down electron bands and gives rise to a spin polarization of the conductance. The conductance vanishes when the Fermi energy matches the adatom levels due to the coupling of adatom localized states with the continuum spectra of the nanoribbon. This is the well-known Fano effect, resulting in a spin-dependent antiresonance in the conductance. The different antiresonance energies of spin-up and spin-down electrons give rise to a full spin polarization of the conductance in a broad energy window. This spin-dependent Fano effect opens the possibility to using it in spintronics as a tuneable source of polarized electrons
Photoabsorption and photoion spectroscopy of atomic uranium in the region of 6p and 5d excitations

The photoabsorption process in atomic uranium has been investigated experimentally and theoretically in the 15–150-eV region. Using the dual laser plasma technique, the 6p photoabsorption spectrum has been recorded while for the first time the 5d region has been remeasured photoelectrically using both photoabsorption and photoion spectroscopy. Interpretation of the photoabsorption spectra is supported by Hartree-Fock calculations which take into account spin-flip decay and the interaction of many discrete states with many continua. The 6p spectrum is entirely dominated by spin-orbit split 6p⃗6d transitions. The 5d-subshell photoabsorption is shown to consist predominantly of discrete 5d⃗5f excitations; here the electrostatic and spin-orbit interactions are comparable in strength
Towards an understanding of game software development processes: a case study

This paper aims to fill the gap that exists about software development processes in game development in the research literature, and address the gap in the research literature by investigating and reporting information about the software development processes used in game development. To investigate the role of the software development process in relation to the game development process, and to better understand the processes and practices used in game software development, a single industrial based case study was undertaken and reported to investigate in a real world context the software development processes and practices used in game development. This research contributes to our knowledge of the field of game development and potentially forms the foundation for further research in the area
Real time signal processing and data handling with dedicated hardware in handheld OCT device

The manuscript presents the topics on real time signal processing with dedicated hardware presented at the INFIERI Summer School 2014. The focus of this work is on real-time signal processing, filtering and massive parallel computing. In general, medical devices have stringed demands on energy consumption as well as on data processing and handling. In fact, the development of novel medical devices has led to significant advances in fields such as instrumentation, algorithm development and image processing.\ud
\ud
In this manuscript, two aspects of the design are brought into consideration: the transformation of a conventional signal processing algorithm into an equivalent version that is suitable for hardware implementation and the use of on-chip modules originally developed for mass-electronics applications, for high speed data transmission. The development of a novel state-of-the-art hand-held OCT probe is used to exemplify theses aspects. In particular, the ``design process'' behind the implementation of a multichannel quadrature coherent demodulator is disclosed
Disagreement between correlations of quantum mechanics and stochastic electrodynamics in the damped parametric oscillator

Intracavity and external third order correlations in the damped nondegenerate parametric oscillator are calculated for quantum mechanics and stochastic electrodynamics (SED), a semiclassical theory. The two theories yield greatly different results, with the correlations of quantum mechanics being cubic in the system\u27s nonlinear coupling constant and those of SED being linear in the same constant. In particular, differences between the two theories are present in at least a mesoscopic regime. They also exist when realistic damping is included. Such differences illustrate distinctions between quantum mechanics and a hidden variable theory for continuous variables
Drivers of and Barriers to Professionalization in International Sport Federations

In a changing and complex environment, international sport federations (IFs) have to face new challenges. These challenges can trigger or hinder IFs’ professionalization processes. While researchers have examined organizational change and professionalization of national sport federations (NFs) and clubs, studies on IFs are rare. Considering professionalization as an important element of IFs’ change processes in recent years, the study attempts to fill this gap. The conceptual framework is based on the concepts and dynamics of organizational change, the influence of isomorphic pressures and the operationalization of a multi-level framework. Data from six case studies was analyzed by means of qualitative content analysis. Findings reveal multiple causes of IFs’ professionalization. Three particular findings are discussed: professionalization as a dynamic process with phases of acceleration that vary depending on IFs’ size; IFs’ becoming increasingly business-like through isomorphic changes; and five causes of particular relevance to IFs’ current professionalization process
Examining Customer Relationship Management from a management fashion perspective

Despite mixed performance reviews and experiences, customer relationship management (CRM) is among the most widely used and discussed management ideas by managers around the world. Commentators have noted that CRM has become “big business” and that there are many commercial actors selling CRM solutions. Despite such observations, little academic research has examined CRM using theories about management fads and fashions. Using management fashion theory as an analytical
lens, this paper casts lights on the emergence and evolution of the market for CRM. The analysis of the supply side of CRM shows that many different actors have been involved, e.g. consulting firms, software vendors, industry analyst firms, and conference organizers. On the demand side, the interest in and usage of CRM remains relatively high despite mixed implementation experiences and failure cases. Based on the analysis, CRM has yet to enter into a downturn phase as is typical of transient management fashions. The longevity and staying power of the CRM fashion can partly be explained by institutional activities carried out by software firms, consultants, and IT industry analysts in training and certifying users, and in developing various complementary products and services. However, similar to what has been observed in relation to other management idea movements, a continuing high number of high-profile failure cases could “wear out” CRM. Therefore, the extent to which organizations are able to capitalize on CRM will likely shape the future trajectory of the CRM idea
Voltammetric Oxidation of Drugs of Abuse I. Morphine and Metabolites

A detailed study of the electrochemical oxidative behavior of morphine in aqueous solution is reported. Through the synthesis of several metabolites and derivatives, pseudomorphine, morphine N-oxide, normorphine, dihydromorphine and 2-(N,N-dimethylaminomethyl)morphine, and their voltammetric study it was possible to identify the oxidation peaks for morphine. The anodic waves are related with the oxidation of phenolic and tertiary amine groups. It is also possible to verify that a poorly defined peak observable during morphine oxidation is not a consequence of further oxidation of pseudomorphine but due to formation of a dimer during phenolic group oxidation. The results obtained and especially those regarding the formation of a new polymer based on a C-O coupling could be useful for clarifying the discoloration phenomenon occurring during storage of morphine solutions as well as leading to a better understanding of its oxidative metabolic pathways.http://dx.doi.org/10.1002/elan.20030296
Hidden beauty molecules within the local hidden gauge approach and heavy
  quark spin symmetry

Using a coupled channel unitary approach, combining the heavy quark spin
symmetry and the dynamics of the local hidden gauge, we investigate the
meson-meson interaction with hidden beauty and obtain several new states. Both
I=0 and I=1 states are analyzed and it is shown that in the I=1 sector, the
interactions are too weak to create any bound states within our framework. In
total, we predict with confidence the existence of 6 bound states, and weakly
bound 6 more possible states. The existence of these weakly bound states depend
on the influence of the coupled channel effects
M-theory Compactifications to Three Dimensions with M2-brane Potentials

We study a class of compactifications of M-theory to three dimensions that
preserve N=2 supersymmetry and which have the defining feature that a probe
space-time filling M2 brane feels a non-trivial potential on the internal
manifold. Using M-theory/F-theory duality such compactifications include the
uplifts of 4-dimensional N=1 type IIB compactifications with D3 potentials to
strong coupling. We study the most general 8-dimensional manifolds supporting
these properties, derive the most general flux that induces an M2 potential,
and show that it is parameterised in terms of two real vectors. We study the
supersymmetry equations when only this flux is present and show that over the
locus where the M2 potential is non-vanishing the background takes the form of
a Calabi-Yau three-fold fibered over a 2-dimensional base spanned by the flux
vectors, while at the minima of the potential the flux vanishes. Allowing also
for non-vanishing four-form flux with one leg in the internal directions we
find that the Calabi-Yau three-fold in the fibration is replaced by an
SU(3)-structure manifold with torsion classes satisfying 2 W_4=-W_5.Comment: 40 page
Tools for incorporating a D-wave contribution in Skyrme energy density
  functionals

The possibility of adding a D-wave term to the standard Skyrme effective
interaction has been widely considered in the past. Such a term has been shown
to appear in the next-to-next-to-leading order of the Skyrme pseudo-potential.
The aim of the present article is to provide the necessary tools to incorporate
this term in a fitting procedure: first, a mean-field equation written in
spherical symmetry in order to describe spherical nuclei and second, the
response function to detect unphysical instabilities. With these tools it will
be possible to build a new fitting procedure to determine the coupling
constants of the new functional
Effect of Sb on the quantum efficiency of GaInP solar cells

The energy bandgap of GaInP solar cells can be tuned by modifying the degree of order of the alloy. In this study, we employed Sb to increase the energy bandgap of the GaInP and analyzed its impact on the performance of GaInP solar cells. An effective change in the cutoff wavelength of the external quantum efficiency of GaInP solar cells and an effective increase of 50 mV in the open-circuit voltage of GaInP/Ga(In)As/Ge triple junction solar cells were obtained with the use of Sb.

A potential contributory role for ciliary dysfunction in the 16p11.2 600 kb BP4-BP5 pathology

The 16p11.2 600 kb copy-number variants (CNVs) are associated with mirror phenotypes on BMI, head circumference, and brain volume and represent frequent genetic lesions in autism spectrum disorders (ASDs) and schizophrenia. Here we interrogated the transcriptome of individuals carrying reciprocal 16p11.2 CNVs. Transcript perturbations correlated with clinical endophenotypes and were enriched for genes associated with ASDs, abnormalities of head size, and ciliopathies. Ciliary gene expression was also perturbed in orthologous mouse models, raising the possibility that ciliary dysfunction contributes to 16p11.2 pathologies. In support of this hypothesis, we found structural ciliary defects in the CA1 hippocampal region of 16p11.2 duplication mice. Moreover, by using an established zebrafish model, we show genetic interaction between KCTD13, a key driver of the mirrored neuroanatomical phenotypes of the 16p11.2 CNV, and ciliopathy-associated genes. Overexpression of BBS7 rescues head size and neuroanatomical defects of kctd13 morphants, whereas suppression or overexpression of CEP290 rescues phenotypes induced by KCTD13 under- or overexpression, respectively. Our data suggest that dysregulation of ciliopathy genes contributes to the clinical phenotypes of these CNVs
Structural and nanomechanical comparison of epitaxially and solution-grown amyloid β25-35 fibrils

Aβ25-35, the fibril-forming, biologically active toxic fragment of the full-length amyloid β-peptide also forms fibrils on mica by an epitaxial assembly mechanism. Here we investigated,\ud
by using atomic force microscopy, nanomechanical manipulation and FTIR spectroscopy, whether the epitaxially-grown fibrils display structural and mechanical features similar to the\ud
ones evolving under equilibrium conditions in bulk solution. Unlike epitaxially-grown fibrils, solution-grown fibrils displayed a heterogeneous morphology and an apparently helical\ud
structure. While fibril assembly in solution occurred on a time scale of hours, on mica surface fibrils appeared within a few minutes. Both types of fibrils showed a similar plateau-like\ud
nanomechanical response characterized by the appearance of force staircases. The IR spectra of both fibril types contained an intense peak between 1620 and 1640 cm-1 indicating that β-\ud
sheets dominate their structure. A shift in the amide I band towards greater wavenumbers in epitaxially assembled fibrils suggests that their structure is less compact than that of solution grown fibrils. Thus, equilibrium conditions are required for a full structural compaction.\ud
Epitaxial Aβ25-35 fibril assembly, while significantly accelerated, may trap the fibrils in less compact configurations. Considering that under in vivo conditions the assembly of amyloid fibrils is influenced by the presence of extracellular matrix components, the ultimate fibril\ud
structure is likely to be influenced by the features of underlying matrix elements
MOSAIIC : City-Level Agent-Based Traffic Simulation Adapted to Emergency Situations

International audienceIn this paper, we present MOSAIIC, an agent-based model to simulate the road traffic of a city in the context of a catastrophic event. Whether natural (cyclone, earthquake, flood) or human (industrial accident) in origin, catastrophic situations modify both infrastructures (buildings, road networks) and human behaviors, which can have a huge impact on human safety. Because the heterogeneities of human behaviors, of land-uses and of network topology have a great impact on the traffic flows, the agent-based modeling is particularly adapted to this subject. In this paper, we focus on the new traffic model itself: the way geographical data is used to build a network, the various behaviors of our agents, from the individual to the collective level
Visual motion disambiguation by a subliminal sound

There is growing interest in the effect of sound on visual motion perception. One model involves the illusion created when two identical objects moving towards each other on a two-dimensional visual display can be seen to either bounce off or stream through each other. Previous studies show that the large bias normally seen toward the streaming percept can be modulated by the presentation of an auditory event at the moment of coincidence. However, no reports to date provide sufficient evidence to indicate whether the sound bounce-inducing effect is due to a perceptual binding process or merely to an explicit inference resulting from the transient auditory stimulus resembling a physical collision of two objects. In the present study, we used a novel experimental design in which a subliminal sound was presented either 150 ms before, at, or 150 ms after the moment of coincidence of two disks moving towards each other. The results showed that there was an increased perception of bouncing (rather than streaming) when the subliminal sound was presented at or 150 ms after the moment of coincidence compared to when no sound was presented. These findings provide the first empirical demonstration that activation of the human auditory system without reaching consciousness affects the perception of an ambiguous visual motion display
The Implementation of Participatory Democracy in French Communes

http://www.palgrave-journals.com/fp/journal/v7/n1/full/fp20095a.htmlInternational audienceThe purpose of the article is to analyze how participatory democracy has been implemented in French communes. The question of neighbourhood democracy is a norm of political speech as local representatives need to legitimize their role in public space by getting closer to their electors. Does the implementation of participatory tools depend on the ideology and the socialization of the mayors or on the structure of the commune (size, territorial configuration)?<br />The paper will mainly use a quantitative investigation made on communes above 5 000 inhabitants as well as interviews conducted in specific communes which were known for their participatory culture
Bootstrap clustering for graph partitioning

International audienceGiven a simple undirected weighted or unweighted graph, we try to cluster the vertex set into communities and also to quantify the robustness of these clusters. For that task, we propose a new method, called bootstrap clustering which consists in (i) defining a new clustering algorithm for graphs, (ii) building a set of graphs similar to the initial one, (iii) applying the clustering method to each of them, making a profile (set) of partitions, (iv) computing a consensus partition for this profile, which is the final graph partitioning. This allows to evaluate the robustness of a cluster as the average percentage of partitions in the profile joining its element pairs ; this notion can be extended to partitions. Doing so, the initial and consensus partitions can be compared. A simulation protocol, based on random graphs structured in communities is designed to evaluate the efficiency of the Bootstrap Clustering approach
The process of burnout among high-performance sport coaches

Avhandling (doktorgrad) - Norges idrettshøgskole, 2015Introduction: High-performance coaches have a highly demanding job and they work inconvenient work hours (e.g., Olusoga et al., 2009; Thelwell et al., 2008b). They are also described as highly motivated for their sport and job (McLean et al., 2012). This combination can put them at risk of experiencing burnout (Pines, 1993). Burnout is a work-related syndrome that develops over time and is characterized by exhaustion, cynicism, and a reduced personal accomplishment (Maslach &amp; Schaufeli, 1993). As of today, longitudinal research conducted to better understand the burnout process within this population is scarce. Aim: Examine (a) whether high-performance coaches experience an increase in burnout over a competitive season and explore associated symptoms, (b) whether the selfdetermination theory process model (Williams et al., 2004) could be a valuable framework to better understand the process of burnout, where both motivational and workload related variables serve as explanatory mechanisms.Paper I: Bentzen, M., Lemyre, P.

The European Union Emissions Trading Scheme: should we throw the flagship out with the bathwater?

International audienceThe European Union Emissions Trading System (EU ETS), presented as the " flagship " of European climate policy, is subject to many criticisms from different stakeholders: it does not reduce carbon emissions nor generate enough low-carbon innovation, it induces competitiveness losses and carbon leakage, its distributional effects are unfair and finally, it is susceptible to fraud. We review these criticisms and recognize that: abatement is real (though small), innovation is insufficient, competitiveness losses and carbon leakage did not seem to take place, distributional effects have indeed been unfair and fraud has been important. Some of these problems could have been avoided. They can still be corrected by reforming the ETS through the introduction of price limits and by developing complementary policies, both because the ETS reform may fail and because the ETS cannot address all the relevant market failures
