description: We investigated the electronic superstructure of graphite surface in the vicinity to monoatomic armchair step edges with scanning tunneling microscopy and spectroscopy. Only the ($\sqrt{3}\times\sqrt{3}$)$\textit{R}$30$^{\circ}$ superstructure is visualized near atomically clean armchair edges, while the honeycomb superstructure is absent. The spectroscopic mapping near the clean armchair edge clearly reveals the ($\sqrt{3}\times\sqrt{3}$)$\textit{R}$30$^{\circ}$ superstructure on both sides of the step edge. We have also visualized a mixture of ($\sqrt{3}\times\sqrt{3}$)$\textit{R}$30$^{\circ}$ and honeycomb superstructures near structurally defective armchair edges. Our results suggest that the honeycomb superstructure pattern results from superposition of two sets of ($\sqrt{3}\times\sqrt{3}$)$\textit{R}$30$^{\circ}$ superstructure with different phases. Our observation solves the mystery of the coexistence of two types of superstructures reported by prior studies.

description: A Multi-Conjugate Adaptive Optics (MCAO) testbed has been developed at the Instituto de AstrofAsica de Canarias (IAC) as a prototype of the Adaptive Optics (AO) system for the European Solar Telescope (EST). EST is a 4.2-m telescope that will provide high resolution in a 60 arcsec circular Field of View (FoV). For this purpose, EST will be equipped with an MCAO system that will be integrated into the telescope\'s optical path. The aim of the testbed is to analyse different sensing and wavefront correction strategies in order to check their suitability for EST. The testbed is a downscaled version of the telescope that has been designed to replicate its main features, including the telescope aperture, the FoV and the atmospheric conditions representatives of the telescope site. It allows to set up of Single Conjugate Adaptive Optics (SCAO), Ground Layer Adaptive Optics (GLAO) and MCAO configurations, both for point-like and extended sources. For this purpose, three Shack-Hartmann Wavefront Sensors (SH-WFSs) have been developed and installed in the testbed. A High-Order Wavefront Sensor (HO-WFS) with 33x33 subapertures senses the on-axis 10 arcsec FoV. Additionally, a Multi-Directional WFS (MD-WFS) estimates the turbulence over the entire atmospheric volume. This WFS provides two possible configurations: one high-order spatial resolution (HO-MD-WFS) and another low-order spatial resolution (LO-MD-WFS). A pupil-conjugated deformable mirror (DM) with 820 actuators is currently available for SCAO and GLAO configurations. The introduction of two DMs conjugated to different altitudes will allow the correction of the wide field. The main aim of this contribution is to present the current state of the testbed and the first tests using a Multi-Directional WFS to perform the wavefront reconstruction. The test results show a possible approach to analyse the behaviour of the control loop of an adaptive optics system. It is discussed whether control quality metrics can be used as an alternative to classical optical quality metrics that are especially hard to standardize for solar observation. These metrics are relevant due to the amount of data for GLAO.
Contextualizing Concepts using a Mathematical Generalization of the Quantum Formalism

description: We outline the rationale and preliminary results of using the State Context Property (SCOP) formalism, originally developed as a generalization of quantum mechanics, to describe the contextual manner in which concepts are evoked, used, and combined to generate meaning. The quantum formalism was developed to cope with problems arising in the description of (1) the measurement process, and (2) the generation of new states with new properties when particles become entangled. Similar problems arising with concepts motivated the formal treatment introduced here. Concepts are viewed not as fixed representations, but entities existing in states of potentiality that require interaction with a context--a stimulus or another concept--to 'collapse' to an instantiated form (e.g. exemplar, prototype, or other possibly imaginary instance). The stimulus situation plays the role of the measurement in physics, acting as context that induces a change of the cognitive state from superposition state to collapsed state. The collapsed state is more likely to consist of a conjunction of concepts for associative than analytic thought because more stimulus or concept properties take part in the collapse. We provide two contextual measures of conceptual distance--one using collapse probabilities and the other weighted properties--and show how they can be applied to conjunctions using the pet fish problem

description: This paper presents the current state of the global gyrokinetic code ORB5 as an update of the previous reference [Jolliet et al., Comp. Phys. Commun. 177 409 (2007)]. The ORB5 code solves the electromagnetic Vlasov-Maxwell system of equations using a PIC scheme and also includes collisions and strong flows. The code assumes multiple gyrokinetic ion species at all wavelengths for the polarization density and drift-kinetic electrons. Variants of the physical model can be selected for electrons such as assuming an adiabatic response or a ``hybrid'' model in which passing electrons are assumed adiabatic and trapped electrons are drift-kinetic. A Fourier filter as well as various control variates and noise reduction techniques enable simulations with good signal-to-noise ratios at a limited numerical cost. They are completed with different momentum and zonal flow-conserving heat sources allowing for temperature-gradient and flux-driven simulations. The code, which runs on both CPUs and GPUs, is well benchmarked against other similar codes and analytical predictions, and shows good scalability up to thousands of nodes.

description: We present a new method for improving the performances of variational autoencoder (VAE). In addition to enforcing the deep feature consistent principle thus ensuring the VAE output and its corresponding input images to have similar deep features, we also implement a generative adversarial training mechanism to force the VAE to output realistic and natural images. We present experimental results to show that the VAE trained with our new method outperforms state of the art in generating face images with much clearer and more natural noses, eyes, teeth, hair textures as well as reasonable backgrounds. We also show that our method can learn powerful embeddings of input face images, which can be used to achieve facial attribute manipulation. Moreover we propose a multi-view feature extraction strategy to extract effective image representations, which can be used to achieve state of the art performance in facial attribute prediction.

description: In West Europe countries, the consultative services had developed for decades backwards, so today are active numerous consultative organizations which differ one from another by organization, financing model and process of consulting. However, the consultative services market in Serbia is very atypical, with massive number of small consultative organizations and extremely small number of big companies. Taking into consideration other well defined markets, the consultative market is susceptible to continuous changes, which is normal regarding specificity of businesses they do, and emergency to research permanently new forms of organization and to be ahead of a practice.

description: In direct analogy to the 4-body decay of a heavy scalar particle, the 4-point correlation function of primordial fluctuations carries P and CP information. The CP violation appears as a P-odd angular dependence in the imaginary part of the trispectrum in momentum space. We construct a model with axion-like couplings which leads to observably large CP-violating trispectrum for future surveys. Furthermore, we show the importance of on-shell particle production in observing P- and CP-violating signals. It is impossible to observe these signals from local 4-scalar EFT operators that respect dS isometries, and thus any such observation can rule out single-field EFT with sufficiently small slow-roll parameters. This calculation opens a new frontier of studying P and CP at very high energy scales.

Cosmological implications of old galaxies at high redshifts

description: Old high-$z$ galaxies are important tools for understanding the structure formation problem and may become the key to determine the ultimate fate of the Universe. In this {\it letter}, the inferred ages of the three oldest galaxies at high redshifts reported in the literature are used to constrain the first epoch of galaxy formation and to reanalyse the high-z time scale crisis. The lower limits on the formation redshift $z_f$ depends on the quantity of cold dark matter in the Universe. In particular, if $Ω_m\geq 0.37$ these galaxies are not formed in FRW cosmologies with no dark energy. This result is in line with the Supernovae type Ia measurements which suggest that the bulk of energy in the Universe is repulsive and appears like an unknown form of dark energy component. In a complementar analysis, unlike recent claims favoring the end of the age problem, it is shown that the Einstein-de Sitter model is excluded at high-z by $\sim 3σ$.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.

Weak magnetism for antineutrinos in supernovae

description: Weak magnetism increases antineutrino mean free paths in core collapse supernovae. The parity violating interference between axial and vector currents makes antineutrino-nucleon cross sections smaller then those for neutrinos. We calculate simple, exact correction factors to include recoil and weak magnetism in supernova simulations. Weak magnetism may significantly increase the neutrino energy flux. We calculate, in a diffusion approximation, an increase of order 15% in the total energy flux for temperatures near 10 MeV. This should raise the neutrino luminosity. Weak magnetism also changes the emitted spectrum of $ \barν_x$ (with $x=μ$ or $τ$) and $\barν_e$. We estimate that $\barν_x$ will be emitted about 7% hotter than $ν_x$ because $\barν_x$ have longer mean free paths. Likewise weak magnetism may increase the $\barν_e$ temperature by of order 10%. This increase in temperature coupled with the increase in neutrino luminosity should increase the heating in the low density region outside of the neutrino sphere. This, in turn, could be important for the success of an explosion. It is important to check our results with a full simulation that includes Boltzmann neutrino transport and weak magnetism corrections.

description: The aim of the author of this paper is to familiarize readers with crop insurance in the EU and Serbia. A comparative method of research has been used and the paper presents types of crop insurance policies typical of the European continent. The paper points out the factors which affect the supply of this insurance and the demand for it. Since premium subsidy is one of the important features of this insurance a part of this paper relates to this issue. The crop insurance in Serbia is also presented here with the conclusion that the crop insurance coverage is very modest. Due to frequent changes of climate and natural disasters it is expected that in the future we will have a growing demand for crop insurance. The unfavorable economic situation, insufficient knowledge and lack of interest of farmers are the main reasons why is crop insurance in Serbia very modest and undeveloped. Because of the frequency of claims and their intensity, this image should be amended.

description: This paper is an attempt to indicate on one of the options for strengthening the competitiveness of the domestic food industry. This possibility is founded in the recognition of product design and packaging as an important factor in competitiveness. In order to determine the extent to which food industry in Serbia believe that the product design and packaging is a factor of competitiveness, a research was undertaken. The basic hypothesis in research was that the reason for bad competitiveness may be conservative attitude towaed design, insufficient investment and lack of incentives. The research included the perception of design as a factor of competitiveness, the practice of food industry in this field, and comparation of this data with data from other industries. Data collected by the empirical research enabled the confirmation of the basic hypothesis. They also gave the recommendations that the enterprises in food industry and creators of development strategies and economic policies should pay special attention on product design and packaging if they want to improve the competitiveness.

With a view to determine the effects of economic crisis on the Serbian companies, the number of 80 businesses of various sizes and forms of ownership. Results indicate that the fear of crisis and decline in sales of products and services. The deterioration in business conditions are mostly influential external factors or in conjunction with the internal. Since environmental factors are most influential in the deterioration of business conditions throughout the economy and reduced purchasing power, and the internal error management.

description: The contemporary judicial protection of registered indication of geographic origin in the Republic of Serbia is regulated allroundly. It means that authorised user of registered indication of geographic origin may be protected in civil, criminal and even special administrative court procedure. This arouses from our country orientation to join to WTO and EU for which one of conditions is to provide protection of intellectual property rights in accordance to mundane and European standards. Upon the last several years in Serbia is adopted more legal prescriptions by which the judicial protection of intellectual property rights is regulated on a proper way. The judicial protection of registered indications of geographic origin is a just a segment of mentioned regulatory process. In this paper authors deal with judicial protection from unauthorised commercial use of registered indication of geographic origin, which is noticeably wider than civil court protection, pointing critically on some inopportune legal solutions regarding criminal and administrative protection as well as on unsustainable legal solutions on civil court procedure which differentiate from general rules of civil law. As for civil law protection of registered indication of geographic origin authors propose its amendment and improvement.

description: Scientific and technological development has spurred large-scale food production, thus enabling a solution, although partial, to one of the biggest global problems of modern civilization – food shortage. Nevertheless, it has been shown that chemicalization and mechanization of agriculture lead to multiple negative environmental impacts and that overuse of pesticides and artificial fertilizers is detrimental to human health. Bearing in mind both local and global tendencies towards necessary ecologization of agriculture in keeping with the generally accepted development model – sustainable development – and acknowledging the opinion that ecological awareness is the basis for avoidance of high-risk activities and mitigation of existing environmental issues, the paper presents data obtained through empirical research pertaining to certain aspects of ecological awareness in individual farmers of the Jablanički County. Based on these data, we concluded that ecological awareness in this part of the population is partially developed.

description: While many people use social network sites to connect with friends and family, some feel that their use is problematic, seriously affecting their sleep, work, or life. Pairing a survey of 20,000 Facebook users measuring perceptions of problematic use with behavioral and demographic data, we examined Facebook activities associated with problematic use as well as the kinds of people most likely to experience it. People who feel their use is problematic are more likely to be younger, male, and going through a major life event such as a breakup. They spend more time on the platform, particularly at night, and spend proportionally more time looking at profiles and less time browsing their News Feeds. They also message their friends more frequently. While they are more likely to respond to notifications, they are also more likely to deactivate their accounts, perhaps in an effort to better manage their time. Further, they are more likely to have seen content about social media or phone addiction. Notably, people reporting problematic use rate the site as more valuable to them, highlighting the complex relationship between technology use and well-being. A better understanding of problematic Facebook use can inform the design of context-appropriate and supportive tools to help people become more in control.

The Linearity of Quantum Mechanics at Stake: The Description of Separated Quantum Entities

description: We consider the situation of a physical entity that is the compound entity consisting of two 'separated' quantum entities. In earlier work it has been proven by one of the authors that such a physical entity cannot be described by standard quantum mechanics. More precisely, it was shown that two of the axioms of traditional quantum axiomatics are at the origin of the impossibility for standard quantum mechanics to describe this type of compound entity. One of these axioms is equivalent with the superposition principle, which means that separated quantum entities put the linearity of quantum mechanics at stake. We analyze the conceptual steps that are involved in this proof, and expose the necessary material of quantum axiomatics to be able to understand the argument

description: In this article, we investigate the temperature and chemical potential dependence of the optical conductivity of graphene, within a field theoretical representation in the continuum approximation, arising from an underlying tight-binding atomistic model, that includes up to next-to-nearest neighbor coupling. Our calculations allow us to obtain the dependence of the optical conductivity on frequency, temperature and finite chemical potential, generalizing our previously reported calculations at zero temperature, and reproducing the universal and experimentally verified value at zero frequency.

description: The gravitational potential responsible for the lensing effect in SBS 1520+530 is studied over length scales from a few arc-seconds to a few arc-minutes. For this purpose, we use sharply deconvolved Hubble Space Telescope images in the optical and near-IR, in combination with ground based optical data obtained over a wider field-of-view. In particular, we have carried out a multi-color analysis in order to identify groups or clusters of galaxies along the line of sight. Photometric redshifts are measured for 139 galaxies unveiling significant excesses of galaxies 1.0 arcmin, NW and 1.7 arcmin, SW of the main lensing galaxy. The photometric redshift inferred both for the main lensing galaxy and for the galaxy concentrations is z=0.9^{+0.10}_{-0.25}. This is in rough agreement with the measured spectroscopic redshift of the main lensing galaxy, z=0.71 (Burud et al. 2002), suggesting that it is part of a larger group or cluster. We investigate the impact of including the galaxy cluster, first on the modelling of the lensing system, and second on the expected time--delay between the two quasar images.

Remarks on topological models and fractional statistics

description: One of the most intriguing aspects of Chern-Simons-type topological models is the fractional statistics of point particles which has been shown essential for our understanding of the fractional quantum Hall effects. Furthermore these ideas are applied to the study of high Tc superconductivity. We present here an recently proposed model for fractional spin with the Pauli term. On the other hand, in D=4 space-time, a Schwarz-type topological gauge theory with antisymmetric tensor gauge field, namely BF model, is reviewed. Antisymmetric tensor fields are conjectured as mediator of string interaction. A dimensional reduction of the previous model provides a (2+1) dimensional topological theory, which involves a 2-form B and a 0-form $ϕ$. Some recent results on this model are reported. Recently, there have been thoughts of generalizing unusual statistics to extended objects in others space-time dimensions, and in particular to the case of strings in four dimensions. In this context, discussions about fractional spin and antisymmetric tensor field are presented.

description: Type Ia supernovae (SNe Ia) are currently the best probes of the dark energy in the universe. To constrain the nature of dark energy in a model-independent manner, we allow the density of dark energy, $ρ_X(z)$, to be an arbitrary function of redshift. Using simulated data from a space-based supernova pencil beam survey, we find that by optimizing the number of parameters used to parametrize the dimensionless dark energy density, $f(z)=ρ_X(z)/ρ_X(z=0)$, we can obtain an unbiased estimate of both f(z) and $Ω_m$ (assuming a flat universe and that the weak energy condition is satisfied). A plausible supernova pencil beam survey (with a square degree field of view and for an observational duration of one year) can yield about 2000 SNe Ia with $0\le z \le 2$. Such a survey in space would yield SN peak luminosities with a combined intrinsic and observational dispersion of $σ(m_{int})=0.16$ mag. We find that for such an idealized survey, $Ω_m$ can be measured to 10% accuracy, and f(z) can be estimated to $\sim$ 20% to $z \sim 1.5$, and $\sim$ 20-40% to $z \sim 2$, depending on the time dependence of the true dark energy density. Dark energy densities which vary more slowly can be more accurately measured. For the anticipated SNAP mission, $Ω_m$ can be measured to 14% accuracy, and f(z) can be estimated to $\sim$ 20% to $z \sim 1.2$. Our results suggest that SNAP may gain much sensitivity to the time-dependence of f(z) and $Ω_m$ by devoting more observational time to the central pencil beam fields to obtain more SNe Ia at z>1.2. We also find that Monte Carlo analysis gives a more accurate estimate of the dark energy density than the maximum likelihood analysis. (abridged)

description: In earlier work a description of a physical entity is given by means of a state property system and it is proven that any state property system is equivalent to a closure space. In the present paper we investigate the relations between classical properties and connectedness for closure spaces. The main result is a decomposition theorem, which allows us to split a state property system into a number of 'pure nonclassical state property systems' and a 'totally classical state property system'
