Multi-color photometry
Eclipsing binary

description: Kepler Mission’s single-band photometry suffers from astrophysical false positives, the most common of background eclipsing binaries (BEBs) and companion transiting planets (CTPs). Multi-color photometry can reveal the color-dependent depth feature of false positives and thus exclude them. In this work, we aim to estimate the fraction of false positives that are unable to be classified by Kepler alone but can be identified with their color-dependent depth feature if a reference band (z, Ks and TESS) were adopted in follow-up observation. We build up physics-based blend models to simulate multi-band signals of false positives. Nearly 65-95% of the BEBs and more than 80% of the CTPs that host a Jupiter-size planet will show detectable depth variations if the reference band can achieve a Kepler-like precision. Ks band is most effective in eliminating BEBs exhibiting any depth sizes, while z and TESS band prefer to identify giant candidates and their identification rates are more sensitive to photometric precision. Provided the radius distribution of planets transiting the secondary star in binary systems, we derive formalism to calculate the overall identification rate for CTPs. By comparing the likelihood distribution of the double-band depth ratio for BEB and planet models, we calculate the false positive probability (FPP) for typical Kepler candidates. Additionally, we show that the FPP calculation helps distinguish the planet candidate’s host star in an unresolved binary system. The analysis framework of this paper can be easily adapted to predict the multi-color photometry yield for other transit surveys, especially for TESS.

description: The long timescale evolution of a self-gravitating system is generically driven by two-body encounters. In many cases, the motion of the particles is primarily governed by the mean field potential. When this potential is integrable, particles move on nearly fixed orbits, which can be described in terms of angle-action variables. The mean field potential drives fast orbital motions (angles) whose associated orbits (actions) are adiabatically conserved on short dynamical timescales. The long-term stochastic evolution of the actions is driven by the potential fluctuations around the mean field and in particular by "resonant two-body encounters", for which the angular frequencies of two particles are in resonance. We show that the stochastic gravitational fluctuations acting on the particles can generically be described by a correlated Gaussian noise. Using this approach, the so-called $η$-formalism, we derive a diffusion equation for the actions in the test particle limit. We show that in the appropriate limits, this diffusion equation is equivalent to the inhomogeneous Balescu-Lenard and Landau equations. This approach provides a new view of the resonant diffusion processes associated with long-term orbital distortions. Finally, by investigating the example of the Hamiltonian Mean Field Model, we show how the present method generically allows for alternative calculations of the long-term diffusion coefficients in inhomogeneous systems.

description: The \textit{I-V} characteristics of four conducting polymer systems like doped polypyrrole (PPy), poly 3,4 ethylene dioxythiophene (PEDOT), polydiacetylene (PDA) and polyaniline (PA) in as many physical forms have been investigated at different temperatures, quenched disorder and magnetic fields. Transport data clearly confirm the existence of a \textit{single} electric field scale in any system. Based upon this observation, a phenomenological scaling analysis is applied, leading to extraction of a concrete number $x_M$, called nonlinearity exponent. The latter serves to characterize a set of \textit{I-V} curves. The onset field $F_o$ at which conductivity starts deviating from its Ohmic value $σ_0$ scales as $F_o \sim σ_0^{x_M}$. Field-dependent data are shown to be described by Glatzman-Matveev multi-step tunneling model [JETP 67, 1276 (1988)] in a near-perfect manner over nine orders of magnitude in conductivity and five order of magnitudes in electric field. $x_M$ is found to possess both positive and negative values lying between -1/2 and 3/4. There is no theory at present for the exponent. Some issues concerning applicability of the Glatzman-Matveev model are discussed.

description: This research aimed at developing operational assessment tool to minimize the university risk background with the purpose to raise the quality of the educational process. The original mathematical approach is proposed as a means to solve the problem of assuring the quality of education. The method of modified risk thermometer and binary fuzzy relations composition were used as the basic methods of sociological monitoring data analysis to measure the satisfaction of students with educational process. The method of modified risk thermometer identifies the risk background of the educational process, defined by the Key Risk Indicators. The method of fuzzy analysis allows to consider and minimize the existing uncertainty of the educational process and risk background. It is shown on the example that if the university risk background is of high degree, it necessitates taking the complex of management decisions to improve the situation with the risk background. The theoretical significance of the research is in development of the methodology of educational computer monitoring. The application of this methodology raises satisfaction of students and teachers with educational process, objectivity of management decisions and their implementation into educational process in order to normalize the risk temperature, which is the practical significance of the research. The degree of this condition corresponding to the normal one is defined at the next stage and needs taking further management decisions. The described methodology is a universal and efficient tool to revaluate the activity of not only universities but also of any company at risk as well as to organize the process of risk management in social and economic systems.

description: We introduce and apply Hilbert's projective metric in the context of quantum information theory. The metric is induced by convex cones such as the sets of positive, separable or PPT operators. It provides bounds on measures for statistical distinguishability of quantum states and on the decrease of entanglement under LOCC protocols or other cone-preserving operations. The results are formulated in terms of general cones and base norms and lead to contractivity bounds for quantum channels, for instance improving Ruskai's trace-norm contraction inequality. A new duality between distinguishability measures and base norms is provided. For two given pairs of quantum states we show that the contraction of Hilbert's projective metric is necessary and sufficient for the existence of a probabilistic quantum operation that maps one pair onto the other. Inequalities between Hilbert's projective metric and the Chernoff bound, the fidelity and various norms are proven.

description: An optical cable is considered as a multicomponent system, which components are elementary sections of an optical cable. During operation, due to failures of these sections, they are replaced with new ones. The reason for the failures of elementary sections, which we will call local failures, are sudden failures. In addition to sudden failures, there are gradual failures that are a consequence of the fiber aging. There is a need to replace the optical cable as a whole. Such a failure is wear-out or global. The influence of sudden failures on the reliability measures of an optical cable in the conditions of its degradation is considered. To solve this problem, a Markov reliability model was developed, on the basis of which expressions were obtained for calculating the unavailability factor, the average time of operational and inoperable states during the degradation cycle of an optical cable. Methods for determining the probabilities of transitions from one state of degradation to another are proposed. It is shown that the unavailability factor of the optical cable and the average time of operational state on one degradation cycle increase with increasing intensity of sudden failures. The optical cable reliability model presented in this paper can be useful for predicting the operating time of an optical cable.

description: The flow rate of water through an orifice at the bottom of a container depends on the hydrostatic pressure whereas for a dry granular material is nearly constant. But what happens during the simultaneous discharge of grains and liquid from a silo? By measuring the flow rate as a function of time, we found that: (i) different regimes appear, going from constant flow rate dominated by the effective fluid viscosity to a hydrostatic-like discharge depending on the aperture and grain size, (ii) the mixed material is always discharged faster than dry grains but slower than liquid, (iii) for the mixture, the liquid level drops faster than the grains level but they are always linearly proportional to one another, and (iv) a sudden growth in the flow rate happens during the transition from a biphasic to a single phase discharge. These results are associated to the competition between the decrease of hydrostatic pressure above the granular bed and the hydrodynamic resistance. A model combining the Kozeny-Carman, Bernoulli and mass conservation equations is proposed and the numerical results are in good agreement with experiments.

description: While monitoring a sample of apparently slowly rotating superficially normal early A stars, we have discovered that HR 8844 (A0 V), is actually a new Chemically Peculiar star. We have first compared the high resolution spectrum of HR 8844 to that of four slow rotators near A0V ($ν$ Cap, $ν$ Cnc , Sirius A and HD 72660) to highlight similarities and differences. The lines of Ti II, Cr II, Sr II and Ba II are conspicuous features in the high resolution high signal-to-noise SOPHIE spectra of HR 8844 and much stronger than in the spectra of the normal star $ν$ Cap. The Hg II line at 3983.93 Å is also present in a 3.5 \% blend. Selected unblended lines of 31 chemical elements from He up to Hg have been synthesized using model atmospheres computed with ATLAS9 and the spectrum synthesis code SYNSPEC48 including hyperfine structure of various isotopes when relevant. These synthetic spectra have been adjusted to the mean SOPHIE spectrum of HR 8844, and high resolution spectra of the comparison stars. Chisquares were minimized in order to derive abundances or upper limits to the abundances of these elements for HR 8844 and the comparison stars. HR 8844 is found to have underabundances of He, C, O, Mg, Ca and Sc, mild enhancements of Ti, V, Cr, Mn and distinct enhancements of the heavy elements Sr, Y, Zr, Ba, La, Pr, Sm, Eu and Hg, the overabundances increasing steadily with atomic number. This chemical pattern suggests that HR 8844 may actually be a new transition object between the coolest HgMn stars and the Am stars.

description: Software engineering is an empirical field of study. To support managerial and technical decision-making, the engineer needs numerical measures closely connected with different software metrics. Visual representation of numerical data improves the effectiveness of human data processing and shows insights that humans may miss. This paper aims to provide a systematic review of the approaches for software metrics visualization and define the possible recommendation for their use. The study is based on the literature review of the papers from two text collections – IEEE Xplore and ACM Digital Library – and the scientometric database Scopus. After merging and filtering, the final set of publications contains 16 papers. Our study showed that there were the metrics used significantly more often; among them are lines-of-code, cyclomatic complexity, coupling, and cohesion. We were not able to identify such leaders for visualization means. Instead, there was a tendency to combine different metrics on one chart or dashboard to provide the whole process picture. Based on the results of empirical studies reported in the literature, we offered an analysis of simple charts’ properties and recommendations on their use for support decision-making in the software engineering process.

description: Although category-specific activation for faces in the ventral visual pathway appears adult-like in adolescence, recognition abilities for individual faces are still immature. We investigated how the ability to represent “individual” faces and houses develops at the neural level. Category-selective regions of interest (ROIs) for faces in the fusiform gyrus (FG) and for places in the parahippocampal place area (PPA) were identified individually in children, adolescents, and adults. Then, using an functional magnetic resonance imaging adaptation paradigm, we measured category selectivity and individual-level adaptation for faces and houses in each ROI. Only adults exhibited both category selectivity and individual-level adaptation bilaterally for faces in the FG and for houses in the PPA. Adolescents showed category selectivity bilaterally for faces in the FG and houses in the PPA. Despite this profile of category selectivity, adolescents only exhibited individual-level adaptation for houses bilaterally in the PPA and for faces in the “left” FG. Children only showed category-selective responses for houses in the PPA, and they failed to exhibit category-selective responses for faces in the FG and individual-level adaptation effects anywhere in the brain. These results indicate that category-level neural tuning develops prior to individual-level neural tuning and that face-related cortex is disproportionately slower in this developmental transition than is place-related cortex.

description: We present measurements performed in a spherical shell filled with liquid sodium, where a 74 mm-radius inner sphere is rotated while a 210 mm-radius outer sphere is at rest. The inner sphere holds a dipolar magnetic field and acts as a magnetic propeller when rotated. In this experimental set-up called DTS, direct measurements of the velocity are performed by ultrasonic Doppler velocimetry. Differences in electric potential and the induced magnetic field are also measured to characterize the magnetohydrodynamic flow. Rotation frequencies of the inner sphere are varied between -30 Hz and +30 Hz, the magnetic Reynolds number based on measured sodium velocities and on the shell radius reaching to about 33. We have investigated the mean axisymmetric part of the flow, which consists of differential rotation. Strong super-rotation of the fluid with respect to the rotating inner sphere is directly measured. It is found that the organization of the mean flow does not change much throughout the entire range of parameters covered by our experiment. The direct measurements of zonal velocity give a nice illustration of Ferraro's law of isorotation in the vicinity of the inner sphere where magnetic forces dominate inertial ones. The transition from a Ferraro regime in the interior to a geostrophic regime, where inertial forces predominate, in the outer regions has been well documented. It takes place where the local Elsasser number is about 1. A quantitative agreement with non-linear numerical simulations is obtained when keeping the same Elsasser number. The experiments also reveal a region that violates Ferraro's law just above the inner sphere.

description: The rapid development of various LBS-oriented applications and services requires the development of new and improvement of known local positioning methods in order to increase the accuracy of determining the user's coordinates. First of all, it connects to methods for determining the location of users in rooms, subject to a high concentration of users and the presence of various difficulties in the propagation of radio signals. To determine the local location of a user in a Wi-Fi/Indoor network, the Fingerprinting method is considered. The comparison of the results of user positioning in the Wi-Fi/Indoor network based on the Fingerprinting method using various algorithms for determining user coordinates, such as the probabilistic Bayesian method and complex approximation using complex planar quadratic splines, was carried out. It has been established that the use of the Fingerprinting local positioning method using quadratic complex flat splines can improve the accuracy of determining the user's location coordinates, thereby ensuring the provision of LBS services and applications to users in the premises.

description: The primary purpose of this paper is to discuss the idea of reliability for research. The authors present methods for calculating statistical reliability. Reliability is crucial for tests intended to be stable across time. That means that if a user conducted a test multiple times, its result should be identical every time. Although it's impossible to determine reliability precisely, there are ways to assess it. Each instrument has an element of reliability. This article focuses on methods for computing reliability in quantitative information, including ratio and interval data. Interval data has equally spaced intervals between the numbers; however, they aren't connected to the actual zero point and do not accurately represent the quantity. Ratio data comprises numbers that represent units that have equal intervals. They are measured from a true zero. Reliability refers to how much the test, process, or instrument (such as an instrument or questionnaire) produces similar results under different conditions as long as nothing else has changed. Stability, internal consistency, and equivalence are all reliability measures employed in research. Stability is the term used to describe the instrument's capacity to give the same results using repeated measurements. Internal consistency refers to all components of the apparatus having an identical concept, feature, or characteristic. Equivalence signifies that the device yields exact results when similar or parallel procedures or instruments are employed.

description: Although at least one quarter of early-type barred galaxies host secondary stellar bars embedded in their large-scale primary counterparts, the dynamics of such double barred galaxies are still not well understood. Recently we reported success at simulating such systems in a repeatable way in collisionless systems. In order to further our understanding of double-barred galaxies, here we characterize the density and kinematics of the N-body simulations of these galaxies. This will facilitate comparison with observations and lead to a better understanding of the observed double-barred galaxies. We find the shape and size of our simulated secondary bars are quite reasonable compared to the observed ones. We demonstrate that an authentic decoupled secondary bar may produce only a weak twist of the kinematic minor axis in the stellar velocity field, due to the relatively large random motion of stars in the central region. We also find that the edge-on nuclear bars are probably not related to boxy peanut-shaped bulges which are most likely to be edge-on primary large-scale bars. Finally we demonstrate that the non-rigid rotation of the secondary bar causes its pattern speed not to be derived with great accuracy using the Tremaine-Weinberg method. We also compare with observations of NGC 2950, a prototypical double-barred early-type galaxy, which suggest that the nuclear bar may be rotating in the opposite sense as the primary.

description: This paper considers the problem of acquiring an unknown target location (among a finite number of locations) via a sequence of measurements, where each measurement consists of simultaneously probing a group of locations. The resulting observation consists of a sum of an indicator of the target's presence in the probed region, and a zero mean Gaussian noise term whose variance is a function of the measurement vector. An equivalence between the target acquisition problem and channel coding over a binary input additive white Gaussian noise (BAWGN) channel with state and feedback is established. Utilizing this information theoretic perspective, a two-stage adaptive target search strategy based on the sorted Posterior Matching channel coding strategy is proposed. Furthermore, using information theoretic converses, the fundamental limits on the target acquisition rate for adaptive and non-adaptive strategies are characterized. As a corollary to the non-asymptotic upper bound of the expected number of measurements under the proposed two-stage strategy, and to non-asymptotic lower bound of the expected number of measurements for optimal non-adaptive search strategy, a lower bound on the adaptivity gain is obtained. The adaptivity gain is further investigated in different asymptotic regimes of interest.

description: The extraordinary dynamism, complexity and ever-increasing interdependence of all transformation processes in the modern world in the face of crisis conditions necessitates strengthening partnerships and coordination of actions at the national, regional and international levels to ensure the quality and sustainability of higher education systems around the world. The research focuses on the successful practical implementation of German-Ukrainian projects of the Anhalt University of Applied Sciences, such as Digin.Net, Digin.Net 2, Study Visits, DigiJED, DigiJED 2, GLSs and Idea-East Hub. Based on the mathematical and statistical methods of analysis, a regression model was built to predict the attraction of funding for the development of education in Ukraine. A meta-analysis of existing practical projects and their financial plans was conducted, considering the definition of specific criteria for successful selection among competitors. Using factor analysis of quantitative and qualitative assessment of the indicators of implemented projects, the authors' model of criteria for successful selection of projects in DAAD was created.

description: The slow kinetics of the oxygen reduction reaction (ORR) is one of the key challenges in developing high performance energy devices, such as solid oxide fuel cells. Straining a film by growing on a lattice-mismatched substrate has been a conventional approach to enhance the ORR activity. However, due to the limited choice of electrolyte substrates to alter the degree of strain, a systematic study in various materials has been a challenge. Here, we explore the strain modulation of the ORR kinetics by growing epitaxial La0.6Sr0.4CoO3-δ (LSCO) films on yttria-stabilized zirconia substrates with the film thickness below and above the critical thickness for strain relaxation. Two orders of magnitude higher ORR kinetics is achieved in an ultra-thin film with ~0.8% tensile strain as compared to unstrained films. Time-of-flight secondary ion mass spectrometry depth profiling confirms that the Sr surface segregation is not responsible for the enhanced ORR in strained films. We attribute this enhancement of ORR kinetics to the increase in oxygen vacancy concentration in the tensile-strained LSCO film owing to the reduced activation barrier for oxygen surface exchange kinetics. Density functional theory calculations reveal an upshift of the oxygen 2p-band center relative to the Fermi level by tensile strain, indicating the origin of the enhanced ORR kinetics.

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/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: One of the charms of mathematics is that it is possible to make elementary discoveries about objects that have been studied for millenia. A most striking example occurred recently when David Bailey of NASA/Ames and Peter Borwein and Simon Plouffe of the Centre for Experimental and Computational Mathematics at Simon Fraser University (henceforth, BBP) discovered a remarkable, and remarkably simple new formula for π. In this paper we will discuss the BBP formula and show how Mathematica can be used to generate many other formulas of the same sort. Moreover, the Mathematica-based methods are symbolic, and so a proof of the formula is a natural consequence of the discovery.

description: We present high resolution N-body/SPH simulations of the interacting cluster 1E0657-56. The main and the sub-cluster are modeled using extended cuspy LCDM dark matter halos and isothermal beta-profiles for the collisional component. The hot gas is initially in hydrostatic equilibrium inside the global potential of the clusters. We investigate the X-ray morphology and derive the most likely impact parameters, mass ratios and initial relative velocities. We find that the observed displacement between the X-ray peaks and the associated mass distribution, the morphology of the bow shock, the surface brightness and projected temperature profiles across the shock discontinuity can be well reproduced by offset 1:6 encounters where the sub-cluster has initial velocity (in the rest frame of the main cluster) close to 2 times the virial velocity of the main cluster dark matter halo. A model with the same mass ratio and lower velocity (1.5 times the main cluster virial velocity) matches quite well most of the observations. However, it does not reproduce the morphology of the main cluster peak. Dynamical friction strongly affects the kinematics of the sub-cluster so that the low velocity bullet is actually bound to the main system at the end of the simulation. We find that a relatively high concentration (c=6) of the main cluster dark matter halo is necessary in order to prevent the disruption of the associated X-ray peak. For a selected sub-sample of runs we perform a detailed three dimensional analysis following the past, present and future evolution of the interacting systems. In particular, we investigate the kinematics of the gas and dark matter components as well as the changes in the density profiles and the motion of the system in the L_X-T diagram.

description: This article presents calculations of the efficiency and power of modules of various technologies using mathematical expressions and equations. In the calculations, we used experimentally measured values of solar radiation, module temperature and passport values of some parameters obtained by module manufacturers under Standard Testing Conditions (STC). The results of analytical calculations and comparisons are presented in graphical and tabular forms. The object of the study, were the following types of photovoltaic modules: silicon monocrystalline (mc-Si), silicon polycrystalline (pc-Si), thin-film based on copper, indium, gallium and selenide (CIGS), thin-film based on cadmium telluride (CdTe). In this work is determined the influence of the temperature factor, external parameters on the energy performance and efficiency of photovoltaic modules. At the maximum module temperature of 85°C, the power losses from nominal power value of the modules, respectively, had the following percentages: pc-Si, mc-Si - 33%, CdTe – 20%, CIGS–29%. According to the calculations the decrease in the efficiency of modules under the influence of heating temperature was 2-2.4% in silicon modules, 0.6-0.7% in thin-film modules.

description: We give solutions to two of the questions in a paper by Brendle, Brooke-Taylor, Ng and Nies. Our examples derive from a 2014 construction by Khan and Miller as well as new direct constructions using martingales. At the same time, we introduce the concept of i.o. subuniformity and relate this concept to recursive measure theory. We prove that there are classes closed downwards under Turing reducibility that have recursive measure zero and that are not i.o. subuniform. This shows that there are examples of classes that cannot be covered with methods other than probabilistic ones. It is easily seen that every set of hyperimmune degree can cover the recursive sets. We prove that there are both examples of hyperimmune-free degree that can and that cannot compute such a cover.

description: In this paper we study the protracted degradation of the soil structure during technogenesis in loess and various types of silty and clay soils. We develop a new mathematical model of the degradation which is based on applying fractal theory to soils, and our modeling is mainly dealing with particle size distribution by volume. The values of the fractal dimension of the particle size distribution by volume were also calculated for various types of soils. The predicted values of the porosity coefficient in the state of complete decomposition of micro-aggregates were calculated according to the new model. The difference of the porosity coefficients in the initial (natural) and predicted states characterizes the value of the volume deformation of the soil. The particle size distribution of the samples was determined before and after several different sample preparation methods. The obtained results on volumetric deformation of loess and silty-clay soils do not contradict the known data on the deformation features of the deposits of the region formed in the epochs of interglacial and terrestrial glaciation.
