description: Cross sections for the reaction ${^1}$H($e,e'π^+$)$n$ were measured in Hall C at Thomas Jefferson National Accelerator Facility (JLab) using the CEBAF high-intensity, continous electron beam in order to determine the charged pion form factor. Data were taken for central four-momentum transfers ranging from $Q^2$=0.60 to 2.45 GeV$^2$ at an invariant mass of the virtual photon-nucleon system of $W$=1.95 and 2.22 GeV. The measured cross sections were separated into the four structure functions $σ_L$, $σ_T$, $σ_{LT}$, and $σ_{TT}$. The various parts of the experimental setup and the analysis steps are described in detail, including the calibrations and systematic studies, which were needed to obtain high precision results. The different types of systematic uncertainties are also discussed. The results for the separated cross sections as a function of the Mandelstam variable $t$ at the different values of $Q^2$ are presented. Some global features of the data are discussed, and the data are compared with the results of some model calculations for the reaction ${^1}$H($e,e'π^+$)$n$.

Marginal distributions for cosmic variance limited CMB polarization data

description: We provide computationally convenient expressions for all marginal distributions of the polarization CMB power spectrum distribution P(C_l|sigma_l), where C_l = {C_l^TT, C_l^TE, C_l^EE, C_l^BB} denotes the set of ensemble averaged polarization CMB power spectra, and sigma_l = {sigma_l^TT, sigma_l^TE, sigma_l^EE, sigma_l^BB} the set of the realization specific polarization CMB power spectra. This distribution describes the CMB power spectrum posterior for cosmic variance limited data. The expressions derived here are general, and may be useful in a wide range of applications. Two specific applications are described in this paper. First, we employ the derived distributions within the CMB Gibbs sampling framework, and demonstrate a new conditional CMB power spectrum sampling algorithm that allows for different binning schemes for each power spectrum. This is useful because most CMB experiments have very different signal-to-noise ratios for temperature and polarization. Second, we provide new Blackwell-Rao estimators for each of the marginal polarization distributions, which are relevant to power spectrum and likelihood estimation. Because these estimators represent marginals, they are not affected by the exponential behaviour of the corresponding joint expression, but converge quickly.

description: There are well-known examples of dynamical systems for which the Birkhoff averages with respect to a given observable along some or all of the orbits do not converge. It has been suggested that such orbits could be classified using higher order averages. In the case of a bounded observable, we show that a classical result of G.H. Hardy implies that if the Birkhoff averages do not converge, then neither do the higher order averages. If the Birkhoff averages do not converge then we may denote by $[α_k,β_k]$ the limit set of the $k$-th order averages. The sequence of intervals thus generated is nested: $[α_{k+1},β_{k+1}] \subset [α_k,β_k]$. We can thus make a distinction among nonconvergent Birkhoff averages; either: B1. $\cap_{k=1}^\infty [α_k,β_k]$ is a point $B_\infty$, or, B2. $\cap_{k=1}^\infty [α_k,β_k]$ is a non-trivial interval $[α_\infty,β_\infty]$. We give characterizations of the types B1 and B2 in terms of how slowly they oscillate and we give examples that exhibit both behaviours B1 and B2 in the context of full shifts on finite symbols and "Bowen's example". For finite full shifts, we show that the set of orbits with type B2 behaviour has full topological entropy.

description: We study a sample of Gamma-Ray Bursts detected by the Swift satellite with known redshift which show a precursor in the Swift-BAT light curve. We analyze the spectra of the precursors and compare them with the time integrated spectra of the prompt emission. We find neither a correlation between the two slopes nor a tendency for the precursors spectra to be systematically harder or softer than the prompt ones. The energetics of the precursors are large: on average, they are just a factor of a few less energetic (in the source rest frame energy range 15-150 keV) than the entire bursts. These properties do not depend upon the quiescent time between the end of the precursor and the start of the main event. These results suggest that what has been called a "precursor" is not a phenomenon distinct from the main event, but is tightly connected with it, even if, in some case, the quiescent time intervals can be longer than 100 seconds.

description: We have performed 2.5D and 3D simulations of conical jets driven by the rotation of an ordered, large-scale magnetic field in a stratified atmosphere. The simulations cover about three orders of magnitude in distance to capture the centrifugal acceleration as well as the evolution past the Alfven surface. We find that the jets develop kink instabilities, the characteristics of which depend on the velocity profile imposed at the base of the flow. The instabilities are especially pronounced with a rigid rotation profile, which induces a shearless magnetic field. The jet's expansion appears to be limiting the growth of Alfven mode instabilities.

Taming the chronology of South Gaulish Samian found at Hadrian's Wall and the German Limes using Linked Open Data

Allen's interval algebra

description: Since the mid-1990s the RGZM (Römisch-Germanisches Zentralmuseum Mainz) provides web-based databases containing millions of datasets with content from many different archaeological disciplines. These relational databases were constructed in interdisciplinary transnational projects and include a lot of “hidden archaeological assumptions”. The aim of our paper is to make these hidden assumptions visible and provide them as a Linked Open Data graph to establish reproducible research as a basis for Open Science.

In particular the Samian Research database [1] at the RGZM which is based on the Names on Terra Sigillata project of Leeds and Reading Universities funded by the AHRC offers nearly 250'000 identified potter stamps, which are traditionally dated in a traditional way. In Roman archaeology this is usually expressed by establishing "absolute dates" in well known “from-to” tables, whereas in reality, the situation is much more diffuse. In fact, Samian dating is quite often based upon so-called ‘dated sites’, which are themselves dated by Samian. Occurrences of South Gaulish Samian on “historically dated sites” like Hadrian’s Wall with its absolute dating or the Wetteraulimes with its less clear dating are difficult to use as dating arguments because it is not possible to say a priori whether these were “survivals” or whether they were part of a still existing South Gaulish export industry. Therefore an RDF (Resource Description Framework) based model has been developed to deal with occurrences making the Samian dating process verifiable and transparent.

This paper focuses on modelling dating arguments using a relative chronology based on Allen’s interval algebra [2] compared with absolute dates in the prototypical build Academic Meta Tool [2] to create Linked Open Data for reproducible and transparent research. This tool enables the creation of an RDF-based ontology such as for modelling dating arguments and visualising the semantic reasoning for detecting errors.

description: It has been recently shown that quantum Boltzman equations may be relevant for leptogenesis. Quantum effects, which lead to a time-dependent CP asymmetry, have been shown to be particularly important for resonant leptogenesis when the asymmetry is generated by the decay of two nearly degenerate states. In this work we investigate the impact of the use of quantum Boltzman equations in the framework ``soft leptogenesis'' in which supersymmetry soft-breaking terms give a small mass splitting between the CP-even and CP-odd right-handed sneutrino states of a single generation and provide the CP-violating phase to generate the lepton asymmetry.

description: We use Bloch oscillations to transfer coherently many photon momenta to atoms. Then we can measure accurately the ratio h/m_Rb and deduce the fine structure constant alpha. The velocity variation due to the Bloch oscillations is measured thanks to Raman transitions. In a first experiment, two Raman $π$ pulses are used to select and measure a very narrow velocity class. This method yields to a value of the fine structure constant alpha^{-1}= 137.035 998 84 (91) with a relative uncertainty of about 6.6 ppb. More recently we use an atomic interferometer consisting in two pairs of pi/2 pulses. We present here the first results obtained with this method.
title:  Ritualization of Shopping and Artistic Interventions into the Temples of Consumption
Creators: name: Tratnik  ,  Polona
Publisher: name: Roma TrE-Press
Year: 2021

description: The globalized world is still in the phase of late capitalism, signified by the establishment of multinational corporations, globalized markets and work, mass consumerism, and the fluid flow of capital. The question of the criticism of art towards the capitalist system, its ideology and consumerism is therefore still topical and is readdressed in this paper. To comprehend the logic of late capitalism, one needs to consider the means of consumption. In order to open space to examine contemporary art as being critical towards consumerism, one also needs to take into consideration the ontological changes that have occurred to art and pay attention to performative art. The author argues that if one is to seek critical or political art in late capitalism, one has to look for artistic interventions into the means of consumption.

Creators: name: Madiyev, Oybek
Publisher: name: University of Kent
Year: 2018

description: This research aims to explore why Russia and China have been more successful in establishing economic cooperation with post-Soviet Uzbekistan than the Western major powers. It will be based on the following key interrelated questions: Why do Russia and China win this so called 'New Great Game'? What is the role of Russia's attempt to reclaim its 'Great Power' status since 2000 and President Putin's attempt to build and expand the Eurasian Economic Union? What were the Chinese competitive strategies that shifted its attention towards Uzbekistan? What is the role of the Shanghai Cooperation Organization (SCO) in China's expanding trade relations with Uzbekistan? How do domestic politics, economics, and culture, formed historically, contribute to shaping Uzbekistan's international engagement? How can we conceptualise Uzbekistan's own post-Soviet foreign economic policy and its decision-making? To address these questions, the research will examine the role of the state and globalisation in Critical International Political Economy (CIPE), utilising mainly a neo-Gramscian approach, and analyse the interaction of various domestic and international factors. Based on these analyses I will show why Uzbekistan has sought to forge a lasting cooperation with the major powers like China and Russia rather than with the West.
title:  The Everyday at the Limits of Representation: Georges Perec’s Things. A Story of the Sixties (1965)
Creators: name: Ewing  ,  David
Publisher: name: Roma TrE-Press
Year: 2021

description: This essay argues that Georges Perec’s novel, Things. A Story of the Sixties (1965) is an aesthetic artefact that helps us to think and experience everyday life. In dramatizing the effects of consumerist dreams and information overload on its protagonists’ lives, the text suggests that everyday experience is opposed to mimesis. However, Perec’s blanket use of the imperfect tense, together with the work of mirroring effects, prevents us from channelling the everyday into the negative space of representation. Rather, the novel speaks to Maurice Blanchot’s suggestion that the everyday is defined by an intransitive escapism. The fabular design of the narrative gives the reader an ethical impetus for tracing the course of this escape, only to find herself ensnared in the text’s economy of desires and representations. On shaky grounds for dismissing the false dreams of the characters, she is invited to reflect on the practical use of mimesis in making her own everyday experience.

description: We revisit the proximity effect produced by QSOs at redshifts 2.1-3.3 applying the FLO approach (Saitta et al. 2008) to a sample of ~6300 Ly-alpha lines fitted in 21 high resolution, high signal-to-noise spectra. This new technique allows to recover the hydrogen density field from the HI column densities of the lines in the Ly-alpha forest, on the basis of simple assumptions on the physical state of the gas. To minimize the systematic uncertainties that could affect the density recovering in the QSO vicinity, we carefully determined the redshifts of the QSOs in our sample and modelled in detail their spectra to compute the corresponding ionising fluxes. The mean density field obtained from the observed spectra shows a significant over-density in the region within 4 proper Mpc from the QSO position, confirming that QSOs are hosted in high density peaks. The absolute value of rho/ for the peak is uncertain by a factor of ~3, depending on the assumed QSO spectral slope and the minimum HI column density detectable in the spectra. We do not confirm the presence of a significant over-density extending to separations of ~15 proper Mpc from the QSO, claimed in previous works at redshifts =2.5 and 3.8. Our best guess for the UV background ionisation rate based on the IGM mean density recovered by FLO is Gamma_UVB ~ 10^{-12} s^{-1}. However, values of Gamma_UVB ~ 3x10^{-12} s^{-1} could be viable if an inverted temperature-density relation with index alpha=-0.5 is adopted.

title:  The Art of Living in a Double House. Everyday Aesthetics in the Space between (East and West)
Creators: name: Berstrand  ,  Tordis
Publisher: name: Roma TrE-Press
Year: 2021

description: The relationship between art and the domestic setting is complicated. A perceived incompatibility between the critical gesture of autonomous art and the protective enclosure of home and house sets the two apart. For the modern architect, art cannot accommodate domestic life without the loss of potency or homely comfort. At the same time, artists in the twentieth century have continued to challenge the resilience of the dwelling house through radical spatial practices producing new spaces and concepts for living. The following looks at the work Merzbau (1927 – 1937) by the German artist Kurt Schwitters (1887 – 1948) as an example of a work of art transforming a seemingly ordinary house into an extraordinary architecture. It is argued that a certain kind of coexistence becomes possible when Schwitters’s Merz building radically challenges the dichotomy of the familiar/unknown embedded in the Western house. Furthermore, it is suggested that the aesthetics of ‘the uncanny’ sheds light on the forces at play when the artist thereby brings something of a foreign nature to the surface of the living space. The thinking of Theodor W. Adorno and Martin Heidegger informs the enquiry into modern Western concepts of dwelling while links to traditional Chinese aesthetics and the more recent ‘living aesthetics’ are developed with a view to a trans-cultural conceptualisation of the inclusive living space.

Plans and values

Publisher: name: University of British Columbia
Year: 2010

description: Floorplans in buildings ace prestructured not only by functional restrictions, but also by attitudes towards preferred conditions. The attitudes are implicit in social and cultural traditions; yet not always are they explicitly stated as program intentions. Each type of institution adheres to a cultural value orientation which defines organisational contexts as preferred paradigms for intended functions, expected activity and supporting conditions. The starting point of this thesis lies in social theory which is used to define four major types of value orientations describing paradigms for human interaction in social organisations. These four are Control, Integration, Prestige and Profit. The main body of this work consists of an application of these four value orientations to the physical attributes of an assortment of building plans for each of four different genotypic organisations: prisons, schools, offices and shopping centres. A building plan is seen as a number of places organized and interrelated by a circulation system. Five generic conditions, of plans of building circulation systems, orient users through various stages towards, into and within the organisational environment. These are location, boundary, layout, paths and edges. The results of analyses of the above parameters show that characteristic conditions of plans essentially support organisational goals and values. The environment created responds to the value intentions of organisations and to the value orientations of users, as well as or instead of functional considerations. For example, the superordinate value orientation of a prison is control, and path (corridor) arrangements reinforce this orientation no matter how dysfunctional they may otherwise be. It is concluded that the value orientations of an institution tie its organisational context to the conditions of a corresponding physical environment. The value orientations are thus pertinent to the rules of building owners, building programmers, and the results illuminate how assumed values condition the way so-called functional requirements are interpreted in institutional architecture.

description: Clusters of galaxies offer a robust test bed for probing the nature of dark matter that is insensitive to the assumption of the gravity theories. Both Modified Newtonian Dynamics (MOND) and General Relativity (GR) would require similar amounts of non-baryonic matter in clusters as MOND boosts the gravity only mildly on cluster scales. Gravitational lensing allows us to estimate the enclosed mass in clusters on small (20 - 50 kpc) and large (several 100 kpc) scales independent of the assumptions of equilibrium. Here we show for the first time that a combination of strong and weak gravitational lensing effects can set interesting limits on the phase space density of dark matter in the centers of clusters. The phase space densities derived from lensing observations are inconsistent with neutrino masses ranging from 2 - 7 eV, and hence do not support the 2 eV-range particles required by MOND. To survive, plausible modifications for MOND may be either an additional degree of dynamical freedom in a co-variant incarnation or mass-varying theories of neutrinos.

description: We present a polarimetric map of a 20'x20' area toward the Galactic center. The polarization of point sources has been measured in the J, H, and Ks bands using the near-infrared polarimetric camera SIRPOL on the 1.4 m telescope IRSF. One percent or better accuracy of polarization degree is achieved for sources with J<14.5, H<13.5, and Ks<12.0. Comparing the Stokes parameters between high extinction stars and relatively low extinction ones, we have obtained a polarization originating from magnetically aligned dust grains at the central region of our Galaxy of at most 1-2 kpc. The distribution of the position angles shows a peak at about 20 deg, nearly parallel to the Galactic plane, suggesting a toroidal magnetic configuration. The derived direction of the magnetic field is in good agreement with that obtained from far-infrared/submillimeter observations, which detect polarized thermal emission from dust in the molecular clouds at the Galactic center. Our results show that by subtracting foreground components, near-infrared polarimetry allows investigation of the magnetic field structure "at" the Galactic center.

description: The Standard Model of particle physics assumes that the so-called fundamental constants are universal and unchanging. Absorption lines arising in molecular clouds along quasar sightlines offer a precise test for variations in the proton-to-electron mass ratio, mu, over cosmological time and distance scales. The inversion transitions of ammonia are particularly sensitive to mu compared to molecular rotational transitions. Comparing the available ammonia spectra observed towards the quasar B0218+357 with new, high-quality rotational spectra, we present the first detailed measurement of mu with this technique, limiting relative deviations from the laboratory value to |dmu/mu| < 1.8x10^{-6} (95% confidence level) at approximately half the Universe's current age - the strongest astrophysical constraint to date. Higher-quality ammonia observations will reduce both the statistical and systematic uncertainties in these measurements.

description: A novel doubly chiral magnetic order is found out in the structurally chiral langasite compound Ba$_3$NbFe$_3$Si$_2$O$_{14}$. The magnetic moments are distributed over planar frustrated triangular lattices of triangle units. On each of these they form the same triangular configuration. This ferro-chiral arrangement is helically modulated from plane to plane. Unpolarized neutron scattering on a single crystal associated with spherical neutron polarimetry proved that a single triangular chirality together with a single helicity is stabilized in an enantiopure crystal. A mean field analysis allows discerning the relevance on this selection of a twist in the plane to plane supersuperexchange paths.

description: We consider the possibility that gravity breaks parity, with left and right handed gravitons coupling to matter with a different Newton's constant and show that this would affect their zero-point vacuum fluctuations during inflation. Should there be a cosmic background of gravity waves, the effect would translate into anomalous CMB polarization. Non-vanishing TB (and EB) polarization components emerge, revealing interesting experimental targets. Indeed if reasonable chirality is present a TB measurement would provide the easiest way to detect a gravitational wave background. We speculate on the theoretical implications of such an observation.

description: While iron emission lines are well studied in black hole systems, both in X-ray binaries and Active Galactic Nuclei, there has been less of a focus on these lines in neutron star low-mass X-ray binaries (LMXBs). However, recent observations with Suzaku and XMM-Newton have revealed broad asymmetric iron line profiles in 4 neutron star LMXBs, confirming an inner disk origin for these lines in neutron star systems. Here, we present a search for iron lines in 6 neutron star LMXBs. For each object we have simultaneous Chandra and RXTE observations at 2 separate epochs, allowing for both a high resolution spectrum, as well as broadband spectral coverage. Out of the six objects in the survey, we only find significant iron lines in two of the objects, GX 17+2 and GX 349+2. However, we cannot rule out that there are weak, broad lines present in the other sources. The equivalent width of the line in GX 17+2 is consistent between the 2 epochs, while in GX 349+2 the line equivalent width increases by a factor of ~3 between epochs as the source flux decreases by a factor of 1.3. This suggests that the disk is highly ionized, and the line is dominated by recombination emission. We find that there appears to be no specific locations in the long-term hardness-intensity diagrams where iron emission lines are formed, though more sources and further observations are required.

Revisiting the radio/X-ray flux correlation in the black hole V404 Cyg: from outburst to quiescence

description: We report results of Chandra X-ray and VLA radio observations of the Galactic accreting black hole V404 Cyg (GS 2023+338) in its quiescent state. V404 Cyg is detected at its faintest level of radio and X-ray emission with a 0.5-10 keV unabsorbed luminosity of 8.3 x 10^32 (d/3.5 kpc)^2 erg/s. The X-ray spectrum fit with an absorbed power-law model yields a photon index of 2.17 +/- 0.13. Contrary to previous findings, this clearly indicates that V404 Cyg undergoes - like most black holes in quiescence - a softening of its X-ray spectrum at very low luminosity compared to the standard hard state. The quiescent radio emission is consistent with the presence of self-absorbed compact jets. We have also reanalyzed archival data from the decay of the 1989 outburst of V404 Cyg in order to quantify more precisely the correlation between radio and X-ray emission in the hard state of V404 Cyg. We show that this correlation extends over five decades in X-ray flux and holds down to the quiescent state of V404 Cyg. The index of this correlation (~0.5) may suggest that synchrotron self-Compton emission is the dominant physical process at high energy in V404 Cyg. However, this index is also consistent with scale invariant jet models coupled to an inefficiently radiating accretion disc. We discuss the properties of the quiescent state of black holes and highlight the fact that some of their properties are different from the standard hard state.

Magnetic-field-driven redistribution between extended and localized electronic states in high-mobility Si MOSFETs at low temperatures

description: In the study of oscillatory electron transport in high-mobility Si MOSFETs at low temperatures we observed two correlated effects in weak in-plane magnetic fields: a steep decrease of the renormalized magnetic susceptibility $χ^*(H)$ and an increase of the concentration of mobile carriers $n(H)$. We suggest a phenomenological model of the magnetic field driven redistribution between the extended and localized electronic states that qualitatively explains both effects. We argue that the redistribution is mainly caused by magnetization of the large-spin localized states with energies close to the Fermi energy $E_F$, coexisting with the majority Fermi liquid state. Our findings also resolve a long-standing disagreement between the experimental data on $χ^*$ obtained in weak ($H \sim k_BT/μ_B$) and strong ($H \sim E_F/gμ_B$) magnetic fields.

description: Vanadium dioxide (VO2) is a phase transition material that undergoes a reversible insulator-metal phase transition at ~ 68 C. Atmospheric pressure thermal oxidation (APTO) of vanadium (V) is a simple VO2 synthesis method in which V thin film is oxidized in open air. For an optimum oxidation duration, VO2 films are obtained with good phase transition properties. We recently reported a modified APTO process using a step temperature profile for oxidation (Thin Solid Films 706, 138003 (2020)). We demonstrated an ultra-low thermal budget synthesis of VO2 thin films with good electrical and optical phase transition properties. For a 130 nm room-temperature RF sputtered V thin film, an optimum oxidation duration of ~ 30 s was obtained. In this work, we study how the starting V film thickness and deposition temperature affects the optimum oxidation duration. V thin films of varying thickness (15-212 nm) and 120 nm thick V films with varying deposition temperature (~27-450 C) are prepared using RF magnetron sputtering. These films are oxidized for different oxidation durations and characterized using Raman and four-probe measurements to find the optimum oxidation duration for each deposition condition. We find that the optimum oxidation duration increases with the increase in V film thickness and V deposition temperature. We model the effect of V film thickness and deposition temperature on the optimal oxidation time using a parabolic law which can be used to obtain the optimal oxidation times for intermediate V thicknesses/deposition temperatures.

description: A quantum mechanical description of particle propagation on the discrete spacetime of a causal set is presented. The model involves a discrete path integral in which trajectories within the causal set are summed over to obtain a particle propagator. The sum-over-trajectories is achieved by a matrix geometric series. For causal sets generated by sprinkling points into 1+1 and 3+1 dimensional Minkowski spacetime the propagator calculated on the causal set is shown to agree, in a suitable sense, with the causal retarded propagator for the Klein-Gordon equation. The particle propagator described here is a step towards quantum field theory on causal set spacetime.

description: The GRACIOUS project has developed a highly innovative science-based framework that supports the assessment of risk posed by the ever increasing array of nanomaterials on the market and under development. The framework streamlines the process for assessing their risk by logically grouping nanomaterials thereby allowing extrapolation between (read-across) nanomaterials and reducing the need to assess exposure to and toxicity on a case by case basis. The Guidance in a Nutshell gives users new to the topic of grouping of nanoforms a brief introduction to the essential elements of the Framework.

description: We study the extent to which the SAGE experiment data indicate the permanence of the solar neutrino flux. It is shown that in the first approximation this flux is constant and its distribution function is unimodal. Using a more detailed analysis one finds out that data of the first years of experiment (1990-1992) demonstrate a time dependence which is slightly different from what was found for the subsequent years (1993-2006). The distinctive feature of the first years of experiment is a high dispersion of neutrino flux in comparison with the following epoch. We discuss possible astronomical consequences of this result.

description: This work introduces a novel approach to keep high-level component-based architecture models consistent with source code during software development and software evolution. The approach helps to avoid architecture drift and architecture erosion, which are two well-known problems that can arise during development and maintenance of a software system. In particular, the presented approach can be used to keep instances of the Palladio Component Model (PCM) consistent with Java source code.

description: Two parts of an entangled quantum state can have a correlation in their joint behavior under measurements that is unexplainable by shared classical information. Such correlations are called non-local and have proven to be an interesting resource for information processing. Since non-local correlations are more useful if they are stronger, it is natural to ask whether weak non-locality can be amplified. We give an affirmative answer by presenting the first protocol for distilling non-locality in the framework of generalized non-signaling theories. Our protocol works for both quantum and non-quantum correlations. This shows that in many contexts, the extent to which a single instance of a correlation can violate a CHSH inequality is not a good measure for the usefulness of non-locality. A more meaningful measure follows from our results.
