description: SST (Satellite to Satellite Tracking) observations between GPS and LEO (Low Earth Orbiter) play an important role to determine precise 3D orbits of LEO satellites. The Zero difference technique has been proven to be very efficient for this task. Zero difference means that the observations between the GPS satellites and the LEO satellite must be used without any differencing (in time or in position). In this work, as a first step to determine precise LEO orbits, initial LEO positions have been estimated based on the Bancroft method with an accuracy of a few meters. These positions can be used subsequently as initial values for LEO positions based on pseudo-range ionosphere free observations. Then the position differences between two sequential epochs can be estimated with an accuracy of approximately 1 cm based on ionosphere free carrier phase observations. The absolutely estimated positions and position differences can be used afterwards to estimate the final absolute positions of a LEO satellite at every epoch, if a sufficient number of GPS satellites i.e. equal or more than four are available.
title: Prospects for the development of biotechnical systems designed based on the human motor system

Publisher: name: Scientific Research Centre "MachineStructure"
Year: 2019

description: The article discusses the existing difficulties in developing various types of biotechnical systems, based on the dynamics of the human motor system, as well as the prospects for their development. As a result of the analysis, it is concluded that the most important areas for improving of biotechnical systems are following: determination of mathematical models that have a fairly high degree of similarity to the corresponding physiological system, as well as the design of methods and criteria for such systems intellectualization. In other words, the control system requires the inclusion of decision-making mechanisms in response to human actions or the mechanisms of intellectual expert assessment of the physiological system condition.
A sample of small size compact steep-spectrum radio sources. VLBI images and VLA polarization at 5 GHz

description: Global VLBI observations at 5 GHz have been performed to study the source morphology in 10 compact steep-spectrum (CSS) sources selected from the Peacock & Wall catalogue with the aim of finding asymmetric structures produced by the interaction with the ambient medium. The combination of these data and earlier 1.7-GHz observations allows the study of the spectral index distribution across the source structure and the unambiguous determination of the nature of each component. In seven sources we detected the core component with a flat or inverted spectrum. In six sources the radio emission has a two-sided morphology and comes mainly from steep-spectrum extended structures, like lobes, jets, and hotspots. Only one source, 0319+121, has a one-sided core-jet structure. In three out of the six sources with a two-sided structure the flux density arising from the lobes is asymmetric, and the brightest lobe is the one closest to the core, suggesting that the jets are expanding in an inhomogeneous ambient medium which may influence the source growth. The interaction between the jet and the environment may slow down the source expansion and enhance the luminosity due to severe radiative losses, likely producing an excess of CSS radio sources in flux density limited samples. The lobes of the other three asymmetric sources have a brighter-when-farther behaviour, in agreement with what is expected by projection and relativistic effects. Simultaneous VLA observations carried out to investigate the polarization properties of the targets detected significant polarized emission (~5.5%) only from the quasar 0319+121.

description: Die folgende Arbeit beschreibt die Herstellung und Untersuchung von elastomeren Schichtsilikat-Nanokompositen unter Verwendung des „Continuous Dynamic Latex Compounding (CDLC)“. CDLC ist eine neuartige Methode zur Herstellung von Kompositen und Nanokompositen aus Latices. Dabei wird ein Latex mit einem gequollenen Füllmaterial vermischt und unter Druck in einer Dehnströmung koaguliert. Die Nanokomposite aus den SBR-, NR- und X-SBR-Latices werden in ihren mechanischen Eigenschaften charakterisiert und daraus Rückschlüsse auf den Exfolierungsgrad der Schichtsilikatplättchen sowie den Zusammenhang zwischen Fällmethode und Exfolierungsgrad gezogen. Weiter wird die Auswahl des Schichtsilikattyps eingegrenzt. Der Einfluss des Fällmittels, und der Zusammenhang zwischen Fällmittel und Vulkanisationsverhalten werden untersucht. Es zeigte sich, dass der Auswahl des Schichtsilikats besondere Bedeutung zukommt. Die Montmorillonite mit den Bezeichnungen „Na+Cloisite“ und „Nanocor PGN“ wirken in Kautschuk-Nanokompositen bei Verwendung der Latexmethode am höchsten verstärkend in Bezug auf die mechanischen Eigenschaften. Montmorillonit mit einem geringem Anteil an Erdalkalimetallkationen, Carbonatanionen und hohem Anteil oktaedrisch koordinierter Aluminiumatome in der Schicht ist für die Verwendung in Nanokompositen aus unpolaren Kautschuken unter Verwendung der Latexmethode am Besten geeignet. Die sehr starke organische Base Diphenylguanidin (DPG) kompensiert teilweise auftretende negative Nebeneffekte in der Vulkanisation durch im Kautschuk verbliebene eher sauer wirkende Bestandteile des Fällmittels. Es wurden Nanokomposite aus selbst hergestellten Sekundärlatices präpariert. Es zeigt sich, dass die Verstärkungswerte der über das Latexmischverfahren hergestellten Komposite denen von mechanisch eingemischten Schichtsilikaten weit überlegen ist. Auf diese Weise lassen sich auch Kautschuke zu einem Nanokomposit verarbeiten, die normalerweise nicht als Latex vorliegen.

description: Polymer fiber swells after exiting the die and upon exiting the extruder forming head the final complex-shaped product is distorted. This leads to rejects and large amounts of waste. Therefore, when designing profile molding extrusion heads, it is also necessary to take into account the effect of extrudate swelling at the exit from the extrusion head and, accordingly, the quantitative parameters of this process to transform the forming channel.

description: We study the indirect detection of dark matter when the local dark matter velocity distribution depends upon position, as expected for the Milky Way and its dwarf spheroidal satellites, and the annihilation cross-section is not purely s-wave. Using a phase-space distribution consistent with the dark matter density profile, we present estimates of cosmic and gamma-ray fluxes from dark matter annihilations. The expectations for the indirect detection of dark matter can differ significantly from the usual calculation that assumes that the velocity of the dark matter particles follows a Maxwell-Boltzmann distribution.

Dual redshift on Planck-scale-curved momentum spaces

description: Several approaches to the investigation of the quantum-gravity problem have provided "theoretical evidence" of a role for the Planck scale in characterizing the geometry of momentum space. One of the main obstructions for a full exploitation of this scenario is the understanding of the role of the Planck-scale-curved geometry of momentum space in the correlations between emission and detection times, the "travel times" for a particle to go from a given emitter to a given detector. These travel times appear to receive Planck-scale corrections for which no standard interpretation is applicable, and the associated implications for spacetime locality gave rise to the notion of "relative locality" which is still in the early stages of investigation. We here show that these Planck-scale corrections to travel times can be described as "dual redshift" (or "lateshift"): they are manifestations of momentum-space curvature of the same type already known for ordinary redshift produced by spacetime curvature. In turn we can identify the novel notion of "relative momentum-space locality" as a known but under-appreciated feature associated to ordinary redshift produced by spacetime curvature, and this can be described in complete analogy with the relative spacetime locality that became of interest in the recent quantum-gravity literature. We also briefly comment on how these findings may be relevant for an approach to the quantum-gravity problem proposed by Max Born in 1938 and centered on Born duality.

Nonconvexity of the relative entropy for Markov dynamics: A Fisher information approach
Creators: name: Polettini, Matteo
name: Esposito, Massimiliano
Publisher: name: arXiv
Year: 2013
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We show via counterexamples that relative entropy between the solution of a Markovian master equation and the steady state is not a convex function of time. We thus let down a curtain on a possible formulation of a principle of thermodynamics regarding decrease of the nonadiabatic entropy production. However, we argue that a large separation of typical decay times is necessary for nonconvex solutions to occur, making concave transients extremely short-lived with respect to the main relaxation modes. We describe a general method based on the Fisher information matrix to discriminate between generators that do and don't admit nonconvex solutions. While initial conditions leading to concave transients are shown to be extremely fine-tuned, by our method we are able to select nonconvex initial conditions that are arbitrarily close to the steady state. Convexity does occur when the system is close to satisfy detailed balance, or more generally when certain normality conditions of the decay modes are satisfied. Our results circumscribe the range of validity of a conjecture proposed by Maes et al. [Phys. Rev. Lett. 107, 010601 (2011)] regarding monotonicity of the large deviation rate functional for the occupation probability (dynamical activity), showing that while the conjecture might still hold in the long time limit, the dynamical activity is not a Lyapunov function.

Antikaons in neutron star studied with recent versions of relativistic mean-field models

Subjects: subject: Nuclear Theory (nucl-th)

description: We study the impact of additional couplings in the relativistic mean field (RMF) models, in conjunction with antikaon condensation, on various neutron star properties. We analyze different properties such as in-medium antikaon and nucleon effective masses, antikaon energies, chemical potentials and the mass-radius relations of neutron star (NS). We calculate the NS properties with the RMF (NL3), E-RMF (G1, G2) and FSU2.1 models, which are quite successful in explaining several finite nuclear properties. Our results show that the onset of kaon condensation in NS strongly depends on the parameters of the Lagrangian, especially the additional couplings which play a significant role at higher densities where antikaons dominate the behavior of equation of state.

On the Behavior of RObust Header Compression U-mode in Channels with Memory

description: The existing studies of RObust Header Compression (ROHC) have provided some understanding for memoryless channel, but the behavior of ROHC for correlated wireless channels is not well investigated in spite of its practical importance. In this paper, the dependence of ROHC against its design parameters for the Gilbert Elliot channel is studied by means of three analytical models. A first more elaborated approach accurately predicts the behavior of the protocol for the single RTP flow profile, while a simpler, analytically tractable model yields clear and insightful mathematical relationships that explain the qualitative trends of ROHC. The results are validated against a real world implementation of this protocol. Moreover, a third model studies also the less conventional yet practically relevant setting of multiple RTP flows.

Early X-ray and optical afterglow of gravitational wave bursts from mergers of binary neutron stars

Year: 2012
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: Double neutron star mergers are strong sources of gravitational waves. The upcoming advanced gravitational wave detectors are expected to make the first detection of gravitational wave bursts (GWBs) associated with these sources. Proposed electromagnetic counterparts of a GWB include a short GRB, an optical macronova, and a long-lasting radio afterglow. Here we suggest that at least some GWBs could be followed by an early afterglow lasting for thousands of seconds, if the post-merger product is a short-lived massive neutron star rather than a black hole. This afterglow is powered by dissipation of a proto-magnetar wind. The X-ray flux is estimated to be as bright as 10^{-8}-10^{-7} erg/s/cm^2. The optical flux is subject to large uncertainties but could be as bright as 17th magnitude in R-band. We provide observational hints of such a scenario, and discuss the challenge and strategy to detect these signals.

description: The spin waves in the multi-k antiferromagnet, USb, soften and become quasielastic well below the AFM ordering temperature, T_N. This occurs without a magnetic or structural transition. It has been suggested that this change is in fact due to de-phasing of the different multi-k components: a switch from 3-k to 1-k behaviour. In this work, we use inelastic neutron scattering with tri-directional polarisation analysis to probe the quasielastic magnetic excitations and reveal that the 3-k structure does not de-phase. More surprisingly, the paramagnetic correlations also maintain the same clear phase correlations well above T_N (up to at least 1.4T_N). This precursor regime has not been observed before in a multi-k system.

description: Numerical simulations of interchange turbulence in the Scrape-Off Layer are performed in a regime relevant for a specific L-mode MAST (Mega Ampere Spherical Tokamak) discharge. Such a discharge was diagnosed with a reciprocating arm equipped with a Gundestrup probe. A detailed comparison of the average and statistical properties of the simulated and experimental ion saturation current is performed. Good agreement is found in the time averaged radial profile, in the probability distribution functions (PDFs) and in qualitative features of the signals such as the shape, duration and separation of burst events. These results confirm the validity of the simple interchange model used and help to identify where it can be improved. Finally, the simulated data are used to assess the importance of the temperature fluctuations on plasma potential and radial velocity measurements acquired with Langmuir probes. It is shown that the correlation between the actual plasma quantities and the signal of the synthetic diagnostics is poor, suggesting that accurate measurements of the temperature fluctuations are needed in order to obtain reliable estimates of the perpendicular fluxes.

description: В настоящей статье авторы обращаются к такому феномену, как проведение информационных акций для того, чтобы оказать коммуникативное воздействие на общество, конечной целью которого является реакция властей. В статье рассматривается одна из таких акций, центральное место в которой занимает форма, заимствованная из кино как области художественной коммуникации. В результате проведенного исследования было выявлено, что в ходе использования художественной формы для передачи реальных идей социального характера устанавливается связь между различными сферами деятельности человека художественной и социальной на основе взаимодействия между вымышленными и реальными событиями. Кроме того, авторы выявили, что в данном случае имеет место процесс межкультурной коммуникации, взаимодействие между американским и британским социумами, поскольку художественное и эмоциональное воздействие американского фильма применяется для передачи идей социального характера в Британии. Авторами также была выявлена и противоположная модель, когда в художественное произведение включаются различные формы социальной коммуникации, в частности, её политические и рекламные символы. Благодаря комбинированию этих символов происходит трансформация художественного дискурса, на поле которого пересекаются политический и рекламный дискурсы: политическая и рекламная формы используются для создания художественного содержания. В результате проведенного исследования авторы приходят к выводу о том, что включение инородных элементов в состав определенного дискурса усиливает его воздействие; это обусловлено контрастом, который они создают и сами с собой, и с принимающим дискурсом; политическая и рекламная формы усиливают свое воздействие через художественное произведение.

description: Using a first-principles Green's function approach we study magnetic properties of the magnetic binary chalcogenides Bi2Te3, Bi2Se3, and Sb2Te3. The magnetic coupling between transition-metal impurities is long-range, extends beyond a quintuple layer, and decreases with increasing number of d electrons per 3d atom. We find two main mechanisms for the magnetic interaction in these materials: the indirect exchange interaction mediated by free carriers and the indirect interaction between magnetic moments via chalcogen atoms. The calculated Curie temperatures of these systems are in good agreement with available experimental data. Our results provide deep insight into magnetic interactions in magnetic binary chalcogenides and open a way to design new materials for promising applications.

description: The present paper is devoted to the problem of representing food in the British media discourse. The author analyzes social and linguistic factors of food representation in the media discourse, in particular, the ideas and social factors that influence the journalists as well as peculiarities of the linguistic forms of food representation. Particular attention is paid to the cognitive aspects: the author analyzes realization of specific cognitive models within the media discourse. The author also studies the cognitive models’ components, which are foregrounded in the media texts, and the linguistic means used for this purpose. The connection between a cognitive model realization and the journalist’s pragmatic goal aimed at positive representation of food in the British media discourse is also studied in the paper. The author comes to a conclusion that the process of food representation in the British media discourse is influenced by a goal, which is to demonstrate a new identity differing from the one that has existed before; within this identity particular attention is paid to eating out and healthy diet.
title: A Bootstrap Test for Informative Intra-Cluster Group Sizes in Clustered Data

description: Clustered data are frequently observed in various domains of scientific and social studies. In a typical clustered data, units within a cluster are correlated while units between different clusters are independent. An example of such clustered data can be found in dental studies where individuals are treated as clusters and the teeth in an individual are the units within a cluster. While analyzing such clustered data, it has been observed that the number of units present in a cluster can be informative in terms of being associated with the outcome from that cluster. Specifically, when the aim is to compare the outcomes from two different groups of units (e.g., upper teeth vs. lower teeth) in a clustered data, then the number of units belonging to a group in a typical cluster, i.e., an intra-cluster group size, can be informative about the outcome from that group in that cluster. Although such clustered data analysis has recently gained importance, there does not exist any formal statistical method for testing the hypothesis that a particular clustered data has informative intra-cluster group sizes (IICGS). However, ignoring the existence of this IICGS during group-based outcome comparisons in a clustered data can result in a biased inference. In this research, we focus on developing a statistical hypothesis testing mechanism that can test a claim of IICGS in a clustered data setting. We use Kolmogorov-Smirnov test-type nonparametric test statistic and a bootstrap hypothesis testing procedure to develop our testing method. Through a variety of simulated data, we demonstrate that our proposed statistical testing method maintains the nominal type-I error rate and has substantial power in identifying IICGS in a clustered data.

description: The possibility in principle of the determining high energy photon circular polarization by the measurement of the created electron polarization in the process of triplet photoproduction $γ+e^-\rightarrow e^+e^- +e^-$ is investigated. The respective event number which depend on polarization states of photon and created electron does not decrease with the growth of the photon energy, and this circumstance can ensure the high efficiency in such kind of experiments. We study different double and single distributions of the created electron (or positron), which allow to probe the photon circular polarization and to measure its magnitude (the Stock's parameter $ξ_2$), using the technique of the Sudakov's variables. Some experimental setups with different rules for event selection are studied and corresponding numerical estimations are presented.

On the interactions of the high energy photoelectrons with the fullerene shell

description: The probability that photoionization of the caged atom in an endohedral system is accompanied by excitation of the fullerene shell is shown to be close to unity in broad intervals of the photoelectron energies. The result is obtained by summation of the perturbative series for the interaction between the photoelectron and the fullerene shell. This result means that the interaction between the photoelectron ejected from the cage atom and the fullerene shell cannot be described by a static potential, since inelastic processes become decisively important.

description: We present a detailed spectroscopic investigation of the young eruptive star PV Cep, to improve our understanding of its nature and characterise its circumstellar environment after its last outburst in 2004. The analysis of our medium-resolution spectroscopy in the near-IR (0.9-2.35 um), collected in 2012 at the Large Binocular Telescope with the IR spectrograph LUCIFER, allows us to infer the main stellar parameters (visual extinction, accretion luminosity, mass accretion and ejection rates), and model the inner disc, jet, and wind. The NIR spectrum displays several strong emission lines associated with accretion/ejection activity and circumstellar environment. Our analysis shows that the brightness of PV Cep is fading, as well as the mass accretion rate (2x10^-7 Msun/yr^-1 in 2012 vs ~5x10^-6 Msun/yr^-1 in 2004), which is more than one order of magnitude lower than in the outburst phase. Among the several emission lines, only the [FeII] intensity increased after the outburst. The observed [FeII] emission delineates blue- and red-shifted lobes, both with high- and low-velocity components, which trace an asymmetric jet and wind, respectively. The observed emission in the jet has a dynamical age of ~8 years, indicating that it was produced during the last outburst. The mass ejection rate in both lobes is 1.5x10^-7 Msun/yr^-1, approximately matching the high accretion rate observed during and immediately after the outburst . The observed jet/outflow asymmetries are consistent with an inhomogeneous medium. Our modelling of the CO emission hints at a small-scale gaseous disc ring, extending from ~0.2-0.4 AU to ~3 AU from the source, with an inner temperature of ~3000 K. Our HI lines modelling indicates that most of the observed emission comes from an expanding disc wind at Te=10000 K. The line profiles are strongly affected by scattering, disc screening, and outflow self-absorption.

High Energy Emission Processes in OJ 287 during 2009 Flare

description: The broadband spectrum of a BL Lac object, OJ 287, from radio to $γ$-rays obtained during a major $γ$-ray flare detected by \emph{Fermi} in 2009 are studied to understand the high energy emission mechanism during this episode. Using a simple one-zone leptonic model, incorporating synchrotron and inverse Compton emission processes, we show that the explanation of high energy emission from X-rays to $γ$-rays, by considering a single emission mechanism, namely, synchrotron self-Compton (SSC) or external Compton (EC) requires unlikely physical conditions. However, a combination of both SSC and EC mechanisms can reproduce the observed high energy spectrum satisfactorily. Using these emission mechanisms we extract the physical parameters governing the source and its environment. Our study suggests that the emission region of OJ 287 is surrounded by a warm infrared (IR) emitting region of $\sim 250 \, K$. Assuming this region as a spherical cloud illuminated by an accretion disk, we obtain the location of the emission region to be $\sim 9 pc$. This supports the claim that the $γ$-ray emission from OJ 287 during the 2009 flare arises from a location far away from the central engine as deduced from millimeter-gamma ray correlation study and very long baseline array images.

description: High pressure injection systems have essential roles in realizing highly controllable fuel injections in internal combustion engines. The primary atomization processes in the near field of the spray, and even inside the injector, determine the subsequent spray development with a considerable impact on the combustion and pollutant formation. Therefore, the processes should be understood as much as possible; for instance, to develop mathematical and numerical models. However, the experimental difficulties are extremely high, especially near the injector nozzle or inside the nozzle, due to the very small geometrical scales, the highly concentrated optical dense spray processes and the high speed and drastic transient nature of the spray. In this study, several unique and partly recently developed techniques are applied for detailed measurements on the flow inside the nozzle and the spray development very near the nozzle. As far as possible, the same three-hole injector for high pressure diesel injection is used to utilize and compare different measurement approaches. In a comprehensive section, the approach is taken to discuss the measurement results in comparison. It is possible to combine the observations within and outside the injector and to discuss the entire spray development processes for high pressure diesel sprays. This allows one to confirm theories and to provide detailed and, in parts, even quantitative data for the validation of numerical models.
