Gluon Dynamics, Center Symmetry and the deconfinement phase transition in SU(3) pure Yang-Mills theory

description: The correlations between the modulus of the Polyakov loop, its phase $θ$ and the Landau gauge gluon propagator at finite temperature are investigated in connection with the center symmetry for pure Yang-Mills SU(3) theory. In the deconfined phase, where the center symmetry is spontaneously broken, the phase of the Polyakov loop per configuration is close to $θ= 0$, $\pm \, 2 π/3$. We find that the gluon propagator form factors associated with $θ\approx 0$ differs quantitatively and qualitatively from those associated to $θ\approx \pm \, 2 π/3$. This difference between the form factors is a property of the deconfined phase and a sign of the spontaneous breaking of the center symmetry. Furthermore, given that this difference vanishes in the confined phase, it can be used as an order parameter associated to the deconfinement transition. For simulations near the critical temperature $T_c$, the difference between the propagators associated to $θ\approx 0$ and $θ\approx \pm \, 2 π/3$ allows to classify the configurations as belonging to the confined or deconfined phase. This establishes a selection procedure which has a measurable impact in the gluon form factors. Our results also show that the absence of the selection procedure can be erroneously taken as lattice artifacts.

description: We present the first experimental characterization of the azimuthal Wigner distribution of a photon. Our protocol fully characterizes the transverse structure of a photon in conjugate bases of orbital angular momentum (OAM) and azimuthal angle (ANG). We provide a test of our protocol by characterizing pure superpositions and incoherent mixtures of OAM modes in a seven-dimensional space. The time required for performing measurements in our scheme scales only linearly with the dimension size of the state under investigation. This time scaling makes our technique suitable for quantum information applications involving a large number of OAM states.

description: We consider an unbounded lattice and at each point of this lattice an anharmonic oscillator, that interacts with its first neighborhoods via a pair potential $V$ and is subjected to a restoring force of potential $U$. We assume that $U$ and $V$ are even nonnegative polynomials of degree $2σ_1$ and $2σ_2$. We study the time evolution of this system, with a control of the growth in time of the local energy, and we give a nontrivial bound on the velocity of propagation of a perturbation. This is an extension to the case $σ_1 < 2σ_2-1$ of some already known results obtained for $σ_1 \geq 2σ_2-1$.

description: We consider a random walk among a Poisson system of moving traps on ${\mathbb Z}$. In earlier work [DGRS12], the quenched and annealed survival probabilities of this random walk have been investigated. Here we study the path of the random walk conditioned on survival up to time $t$ in the annealed case and show that it is subdiffusive. As a by-product, we obtain an upper bound on the number of so-called thin points of a one-dimensional random walk, as well as a bound on the total volume of the holes in the random walk's range.

description: An important question in extragalactic astronomy concerns the distribution of black hole accretion rates of active galactic nuclei (AGN). Based on observations at X-ray wavelengths, the observed Eddington ratio distribution appears as a power law, while optical studies have often yielded a lognormal distribution. There is increasing evidence that these observed discrepancies may be due to contamination by star formation and other selection effects. Using a sample of galaxies from the Sloan Digital Sky Survey Data Release 7, we test if an intrinsic Eddington ratio distribution that takes the form of a Schechter function is consistent with previous work that suggests that young galaxies in optical surveys have an observed lognormal Eddington ratio distribution. We simulate the optical emission line properties of a population of galaxies and AGN using a broad instantaneous luminosity distribution described by a Schechter function near the Eddington limit. This simulated AGN population is then compared to observed galaxies via the positions on an emission line excitation diagram and Eddington ratio distributions. We present an improved method for extracting the AGN distribution using BPT diagnostics that allows us to probe over one order of magnitude lower in Eddington ratio counteracting the effects of dilution by star formation. We conclude that for optically selected AGN in young galaxies, the intrinsic Eddington ratio distribution is consistent with a possibly universal, broad power law with an exponential cutoff, as this distribution is observed in old optically selected galaxies and in X-rays.

Constraining the supersaturation density equation of state from core-collapse supernova simulations - Excluded volume extension of the baryons
Creators: name: Fischer, Tobias

Year: 2016
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

subject: FOS: Physical sciences

description: In this article the role of the supersaturation density equation of state (EOS) is explored in simulations of failed core-collapse supernova explosions. Therefore the nuclear EOS is extended via a one-parameter excluded volume description for baryons, taking into account their finite and increasing volume with increasing density in excess of saturation density. Parameters are selected such that the resulting supernova EOS represent extreme cases, with high pressure variations at supersaturation density which feature extreme stiff and soft EOS variants of the reference case, i.e. without excluded volume corrections. Unlike in the interior of neutron stars with central densities in excess of several times saturation density, central densities of core-collapse supernovae reach only slightly above saturation density. Hence, the impact of the supersaturation density EOS on the supernova dynamics as well as the neutrino signal is found to be negligible. It is mainly determined from the low- and intermediate-density domain, which is left unmodified within this generalized excluded volume approach.

Stationary Axisymmetric Configuration of the Resistive Thick Accretion Tori around a Schwarzschild Black Hole

Year: 2016
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We examine a thick accretion disc in the presence of external gravity and intrinsic dipolar magnetic field due to a non-rotating central object. In this paper, we generalize the Newtonian theory of stationary axisymmetric resistive tori of Tripathy, Prasanna $\&$ Das (1990) by including the fully general relativistic features. If we are to obtain the steady state configuration, we have to take into account the finite resistivity for the magnetofluid in order to avoid the piling up of the field lines anywhere in the accretion discs. The efficient value of conductivity must be much smaller than the classical conductivity to be astrophysically interesting. The accreting plasma in the presence of an external dipole magnetic field gives rise to a current in the azimuthal direction. The azimuthal current produced due to the motion of the magnetofluid modifies the magnetic field structure inside the disc and generates a poloidal magnetic field for the disc. The solutions we have found show that the radial inflow, pressure and density distributions are strongly modified by the electrical conductivity both in relativistic and Newtonian regimes. However, the range of conductivity coefficient is different for both regimes, as well as that of the angular momentum parameter and the radius of the innermost stable circular orbit. Furthermore, it is shown that the azimuthal velocity of the disc which is not dependent on conductivity is sub-Keplerian in all radial distances for both regimes. Owing to the presence of pressure gradient and magnetic forces. This work may also be important for the general relativistic computational magnetohydrodynamics that suffers from the lack of exact analytic solutions that are needed to test computer codes.

description: Studies during the last decade have revealed that nearly all Globular Clusters (GCs) host multiple populations (MPs) of stars with a distinctive chemical patterns in light elements. No evidence of such MPs has been found so far in lower-mass ($< \sim 10^4$ M$_{\odot}$) open clusters nor in intermediate age (1-2 Gyr) massive ($> 10^5$ M$_{\odot}$) clusters in the Local Group. Young massive clusters (YMCs) have masses and densities similar to those expected of young GCs in the early universe, and their near-infrared (NIR) spectra are dominated by the light of red super giants (RSGs). The spectra of these stars may be used to determine the cluster's abundances, even though the individual stars cannot be spatially resolved from one another. We carry out a differential analysis between the Al lines of YMC NGC 1705: 1 and field Small Magellanic Cloud RSGs with similar metallicities. We exclude at high confidence extreme [Al/Fe] enhancements similar to those observed in GCs like NGC 2808 or NGC 6752. However, smaller variations cannot be excluded.

Unique determination of a magnetic Schrödinger operator with unbounded magnetic potential from boundary data

Subjects: subject: Analysis of PDEs (math.AP)

description: We consider the Gel'fand-Calderón problem for a Schrödinger operator of the form $-(\nabla + iA)^2 + q$, defined on a ball $B$ in $\mathbb R^3$. We assume that the magnetic potential $A$ is small in $W^{s,3}$ for some $s>0$, and that the electric potential $q$ is in $W^{-1,3}$. We show that, under these assumptions, the magnetic field $\operatorname{curl} A$ and the potential $q$ are both determined by the Dirichlet-Neumann relation at the boundary $\partial B$. The assumption on $q$ is critical with respect to homogeneity, and the assumption on $A$ is nearly critical. Previous uniqueness theorems of this type have assumed either that both $A$ and $q$ are bounded or that $A$ is zero.
Deep searches for broadband extended gravitational-wave emission in nearby core-collapse supernovae
Creators: name: Van Putten, Maurice H.P.M.
Publisher: name: Zenodo
Year: 2018

description: Broadband extended gravitational-wave emission (BEGE) is a natural outcome from non-axisymmetric accretion flows onto rotating black holes, post-merger of the NS-NS and NS-BH variety or following core-collapse of massive stars. This will be manifest in ascending and descending chirps, the latter in the process of rotating black holes losing angular momentum to matter at the ISCO. To search for BEGE, GPU-accelerated butterfly filtering is presented, based on an earlier discovery of broadband Kolmogorov spectra in long GRBs in the BeppoSAX catalog. This pipeline is illustrated on LIGO S6 and O2, the first showing faint but discernible H1L1 correlations in 'loudness' and 'pitch' obtained against a bank of 8 million templates of one second duration, the latter demonstrated on GW170817. GW170817 shows the need for deep searches, targeting gravitational-wave emission simultaneous with prompt GRB emission, to identify the presence of magnetar or black hole central engines.

description: Aim: To improve treatment plan robustness with respect to small shifts in patient position during the VMAT treatment by ensuring a linear ramp-like dose profile in treatment field overlap regions. Background: Craniospinal irradiation (CSI) is considered technically challenging because the target size exceeds the maximal field size, which necessitates using abutted or overlapping treatment fields. Volumetric modulated arc therapy (VMAT) is increasingly being examined for CSI, as it offers both better dose homogeneity and better dose conformance while also offering a possibility to create field junctions which are more robust towards small shifts in patient position during the treatment. Materials and Methods: A VMAT treatment plan with three isocenters was made for a test case patient. Three groups of overlapping arc field pairs were used; one for the cranial and two for the spinal part. In order to assure a ramp-like dose profile in the field overlap region, the upper spinal part was optimised first, with dose prescription explicitely enforcing a ramp-like dose profile. The cranial and lower spinal part were done afterwards, taking into account the dose contribution of the upper spinal fields. Results: Using simple geometrical reasoning, we demonstrated that hot- and cold spots which arise from small displacement of one treatment field relative to the other treatment field can be reduced by taking two precautions: (a) widening the field overlap region, and (b) reducing the field gradient across the overlap region. The function with the smallest maximal gradient is a linear ramp. We present a treatment planning technique which yields the desired dose profile of the two contributing fields, and minimises dosimetric dependence on minor positional errors in patient set-up.

description: A large dataset of ~2800 spectra extracted from the ELODIE archive was analysed in order to find solar twins. A list of stellar spectra closely resembling the spectrum of the Sun was selected by applying a purely differential method, directly on the fluxes. As solar reference, 18 spectra of asteroids, Moon and blue sky were used. Atmospheric parameters and differential abundances of 8 chemical elements were determined for the solar twin candidates, after a careful selection of appropriate lines. The Li feature of the targets was investigated and additional information on absolute magnitude and age was gathered from the literature. HIP076114 (HD138573) is our best twin candidate, looking exactly like the Sun in all these properties.

description: This paper presents an enhancement to the free surface lattice Boltzmann method (FSLBM) for the simulation of bubbly flows including rupture and breakup of bubbles. The FSLBM uses a volume of fluid approach to reduce the problem of a liquid-gas two-phase flow to a single-phase free surface simulation. In bubbly flows compression effects leading to an increase or decrease of pressure in the suspended bubbles cannot be neglected. Therefore, the free surface simulation is augmented by a bubble model that supplies the missing information by tracking the topological changes of the free surface in the flow. The new model presented here is capable of handling the effects of bubble breakup and coalesce without causing a significant computational overhead. Thus, the enhanced bubble model extends the applicability of the FSLBM to a new range of practically relevant problems, like bubble formation and development in chemical reactors or foaming processes.

While other ensemble creation techniques are based on careful selection of existing classifiers or preprocessing of the data, the presented approach automatically creates an optimal labelling for a number of classifiers, which are then assigned to the original data instances and fed to classifiers. The approach has been evaluated on high-dimensional biomedical datasets. The results show that the approach outperformed individual approaches in all cases.

description: Triptophenolide, a major diterpenoid extracted from Tripterygium wilfordii Hook. f., has been reported to possess significant anti-tumour, anti-androgen and anti-inflammatory activities. However, the metabolic fate of triptophenolide remains unknown. Therefore, this study focused on the metabolic profiling of triptophenolide in rat plasma, urine, bile and faeces following intragastric administration. An ultraperformance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry with combination of extracted ion chromatogram strategy based on 71 typical metabolic reactions was established to comprehensively profile the metabolites of triptophenolide. This strategy allowed for the identification of 17 metabolites from the biosamples. Reduction, oxidation, glucuronide conjugation, and hydroxylation were considered as its main metabolic pathways in vivo. The present study will be greatly helpful for the further pharmacological studies on triptophenolide and would provide valuable information for its clinical application.

description: History of Estonian Newspapers as Seen on the Front Pages This article is based on the materials of the exhibition „Life on the Front Page”, shown at the UT Library from 12 October 2021 to 13 February 2022. The exhibition was put together of 231 front pages of newspapers published in Estonia, Russia, the USA, Sweden and Australia in 1821–2020. The article examines how the front page changed through time and analyses the emergence and development of newspapers as a media in Estonia. Changes in the front page are observed chronologically, starting from the page design and noting its components – texts, different types of advertisements and images. Ultimately, we can see a spiral revealing in the changes in the front page (and in the newspaper as a whole). During the two centuries, the front page of Estonian newspapers has evolved in a winding circle. At the beginning, its design looked like a page of a book, showing only text; it evolved into a newspaper-specific arena for news, displaying both texts and images; it regressed for a while during the Soviet occupation; it continued its arrested development in the 1990s and it is by now incorporating the visual features of a magazine, an advertisement and a poster.

description: Hybrid InSb nanowire-superconductor devices are promising for investigating Majorana modes and topological quantum computation in solid-state devices. An experimental realisation of ballistic, phase-coherent superconductor-nanowire hybrid devices is a necessary step towards engineering topological superconducting electronics. Here, we report on a low-temperature transport study of Josephson junction devices fabricated from InSb nanowires grown by molecular-beam epitaxy and provide a clear evidence for phase-coherent, ballistic charge transport through the nanowires in the junctions. We demonstrate that our devices show gate-tunable proximity-induced supercurrent and clear signatures of multiple Andreev reflections in the differential conductance, indicating phase-coherent transport within the junctions. We also observe periodic modulations of the critical current that can be associated with the Fabry-Pérot interference in the nanowires in the ballistic transport regime. Our work shows that the InSb nanowires grown by molecular-beam epitaxy are of excellent material quality and hybrid superconducting devices made from these nanowires are highly desirable for investigation of the novel physics in topological states of matter and for applications in topological quantum electronics.

description: Academic Library E-service Quality and „Working User” : Conceptual Model Summary of the Doctoral Dissertation The doctoral dissertation proposes a conceptual model of the modern university library e-service and analyses the effect of user participation on the process and outcome of e-service. The author applied both qualitative and quantitative methods; empirical material was gathered at the University of Tartu Library. The dissertation is based on four interrelated studies which focus on the library service quality and the problems of library communication and its transformation. The thesis points out that traditionally, the library’s communication with its users was based on power relations, which found expression in disciplining both the knowledge and the users, and in expertise and taxonomy. These power relations exist even today, but they are changing due to the effect of information society – this transformation is in this dissertation called the communicative turn. Relocation of the services into the web environment increases the share of self-service and the role of the user. This dissertation is based on a theoretical supposition that in conceptualising the quality of the university library e-service it is essential to take into account user participation and to understand the effect it can have on the result of the service. The thesis introduces the notion of „working user” into the librarianship. The working user, who with certain intensity contributes their cognitive and emotional potential to the successful result of e-service, is a new actor in the university librarianship. The author explains that libraries have successfully passed the informational and digital turns, but the communicative turn is still under progress – although library users are actively involved in self-service processes, libraries are still not yet ready to abandon their rigid taxonomic systems and to delegate the control over the system to the users by offering them relevant e-services. The dissertation points out that, on the one hand, it guarantees the quality of the service, but on the other hand, it can be seen as the implicit attempt of the library system to ensure its power over its users and over the knowledge.

The Determination of Sulphur in Foodstuffs Using the Oxygen Flask Technique
Creators: name: Beswick, Gordon
Publisher: name: London South Bank University
Year: 1968

description: The need to estimate the sulphur content of protein containing food directly (i.e. not by applying a factor to the nitrogen content) has recently been realised. The oxygen flask technique, slightly modified, has proved to be a quick and reliable method for the combustion procedure. A literature survey of the methods available for the determination of sulphur has shown that interference often occurs, especially from the phosphate naturally present in many foods. Four promising methods were selected for further study, i.e., 1. Colorimetric method using barium chloranilate, 2. Titrimetric method using barium perchlorate and Thorin as indicator, 3. Turbidimetric method using Tween-80 to stabilize the barium sulphate precipitate. 4. Titration of hydrogen sulphide with mercuric acetate using dithizone: Sulphate is reduced and the hydrogen sulphide is swept into the titration vessel with nitrogen. The difficulties encountered with each method, including interferences, have been investigated and the results are presented and discussed. The turbidimetric and ‘reduction’ methods are shown to be suitable for routine and precise determinations respectively, a number of foodstuffs have been analysed and the results obtained are discussed.

description: The healthy properties of bee pollen mainly depend on the botanical, geographical origin and storage conditions. This study aimed to characterise the composition of volatile compounds and describe the sensory profile of Tuscan bee pollens collected in two different areas in the same period and stored for six months under different conditions. The headspace solid-phase microextraction (HS-SPME) analyses of volatile compounds showed that non-terpene derivatives represented the predominant chemical class in all examined samples, among which aldehydes were the main compounds. Apocaroteonids and oxygenated monoterpenes were also present in lower percentages, with strong separation of the chemical profiles between room temperature samples and those of other storage conditions. The sensory profile was analysed by panel test, the bee pollen produced in the suburban area seemed to show less attractiveness, taste and olfactory. Both samples stored at room temperature showed the worst sensory profile, compared to the other storage conditions.

description: University of Tartu Library Network 2010–2021 University of Tartu Library Network, bringing together the University of Tartu Library and the subject libraries which function as separate units at the university institutes was established in 1999. By the beginning of 2011, the library e-catalogue included the collections of 42 subject libraries. The Library of the Narva College moved to its new location in the recently opened new college building in 2012. The Library is located on the highest floor of the building, enjoying an incredible view on the border river and the cities on both riverbanks. Starting from 2013, the staff members of subject libraries were engaged in a new task of entering student research papers into the UT repository DSpace. In 2020, the subject libraries joined the pilot project where books borrowed from any of the university library network libraries can also be returned to any of the network libraries, not necessarily to the library they were borrowed from. This „inter-library returns” project proved to be so popular that it grew into a regular service to library users. The new university building Delta, housing both the School of Economics and Business Administration and the Institutes of Computer Science and Mathematics and Statistics was opened in 2020. Here, two subject libraries share one and the same library area. The Economics Library and the Mathematics and Computer Science Library, both having their own collections, were located in one and the same library hall, functioning at the same time as separate subject libraries and a unified library. By 2021, the UT Library Network included 29 subject libraries. The recent years have been quite hard for subject libraries’ staff due to COVID-19. However, the challenges have been met and library services have been available for the users. In 2010–2021, staff members of subject libraries also helped the staff of the main library in cleaning books and in the project of pop-up libraries during the main library renovation period, and they also participated in trainings, seminars and study visits.

description: Digitisation Activities at the University of Tartu Library University of Tartu Library, being the oldest and largest research library in Estonia, has paid much attention to the digitisation of its unique collections of diverse materials, starting with rare manuscripts of cultural and scientific historical value, paintings, works of graphic art, photos, maps and historical objects up to dissertations, periodicals and monographs needed for university research and teaching. These collections are unique not only in Estonia but in the wider international context as well. Digitisation is one of the best and in many cases the only method for guaranteeing that the cultural and scientific heritage will as a whole be preserved in the most suitable format and be accessible to as many target groups as possible. Therefore, the library has prioritised the digitisation of its most used and also most at risk collections. This allows to keep critically damaged valuable materials off circulation and helps to ensure their preservation. This article tells about different materials, which have been digitised and made digitally accessible at the UT Library, and about Estonian and international projects where the library has participated.
