description: We perform lattice Monte Carlo simulations for up to 66 unitary fermions in a finite box using a highly improved lattice action for nonrelativistic spin 1/2 fermions. We obtain a value of $0.366^{+0.016}_{-0.011}$ for the Bertsch parameter, defined as the energy of the unitary Fermi gas measured in units of the free gas energy in the thermodynamic limit. In addition, for up to four unitary fermions, we compute the spectrum of the lattice theory by exact diagonalization of the transfer matrix projected onto irreducible representations of the octahedral group for small to moderate size lattices, providing an independent check of our few-body simulation results. We compare our exact numerical and simulation results for the spectrum to benchmark studies of other research groups, as well as perform an extended analysis of our lattice action improvement scheme, including an analysis of the errors associated with higher partial waves and finite temporal discretization.

description: Historically formed national models of accounting and reporting of different countries for a certain period of time met the requirements of the reproduction process within a relatively independent economic system. In the context of the growth of international integration processes, enhancement of the role of transnational corpo-rations, active development of international financial markets and world trade, it became necessary to elimi-nate differences in reporting, which is prepared in different countries. In response to this request, accounting and auditing organizations in a number of countries have developed and implemented unified rules for pre-senting information on financial indicators – International Financial Reporting Standards (IFRS). This al-lowed to make the financial statements clear to users of different countries and ensure comparability of these indicators.
Topological invariants of edge states for periodic two-dimensional models

description: Transfer matrix methods and intersection theory are used to calculate the bands of edge states for a wide class of periodic two-dimensional tight-binding models including a sublattice and spin degree of freedom. This allows to define topological invariants by considering the associated Bott-Maslov indices which can be easily calculated numerically. For time-reversal symmetric systems in the symplectic universality class this leads to a Z_2-invariant for the edge states. It is shown that the edge state invariants are related to Chern numbers of the bulk systems and also to (spin) edge currents, in the spirit of the theory of topological insulators.

The epidemic of spectacles : the HIV/AIDS pandemic, visual culture and the philanthropic documentary archive of the global South
Creators: name: Rajabi Paak, Mina
Publisher: name: University of British Columbia
Year: 2014

description: In the twenty years since the recognition of HIV/AIDS as a pandemic, the disease has become a global challenge, which is not only of medical nature, but also involves various political, social, and cultural factors. As Simon Watney once wrote, “AIDS is not only a medical crisis on an unparalleled scale, it involves a crisis of representation itself” (3). And indeed, HIV/AIDS visual culture and the politics of representation have become integral to our understanding of the meaning of the pandemic. Within the epidemic’s visual culture, AIDS documentaries stand out as one of the most prominent forms of media for narrating the pandemic and creating its global image. My thesis looks at the HIV/AIDS visual culture by documenting and analyzing the transformation of the AIDS documentary archive—both in form and focus—from the radical works of the earlier years (1980s to mid-1990s) in the West to the more conventional documentaries of the later years in and about the global South. Concentrating on this recent AIDS documentary archive concerned with the global South, I discuss how the colonial and stereotypical visuals of the pandemic in the global South find their way into the growing archive of what I call “philanthropic documentaries”: a tradition of globally-oriented documentary making that focuses on the state of the HIV/AIDS epidemic in the global South and which is aimed at attracting financial and political aid from the outsider—mostly Western—viewers by presenting narratives and visuals that initiate effects of shock and sympathy. Yet such well-intentioned filmmaking does as much harm as good by dehumanizing its subjects and failing to show anything other than geographies of despair when it documents the pandemic. Consequently, what the thesis argues for is the need for the formation and growth of an alternative AIDS documentary archive that actively challenges and diversifies what has been established over the years as the image of the pandemic in the global South by philanthropic documentaries and other visual representations of the like, through destabilizing the normative spectacles of the pandemic, representing the excluded and marginalized narratives and, most importantly, visibilizing its own frames.

description: We investigate properties of the formula $p \to \Box p$ in the basic modal logic K. We show that K satisfies an infinitary weaker variant of the rule of margins $ϕ\to \Boxϕ/ ϕ, \negϕ$, and as a consequence, we obtain various negative results about admissibility and unification in K. We describe a complete set of unifiers (i.e., substitutions making the formula provable) of $p \to \Box p$, and use it to establish that K has the worst possible unification type: nullary. In well-behaved transitive modal logics, admissibility and unification can be analyzed in terms of projective formulas, introduced by Ghilardi; in particular, projective formulas coincide for these logics with formulas that are admissibly saturated (i.e., derive all their multiple-conclusion admissible consequences) or exact (i.e., axiomatize a theory of a substitution). In contrast, we show that in K, the formula $p \to \Box p$ is admissibly saturated, but neither projective nor exact. All our results for K also apply to the basic description logic ALC.

Solution of the relativistic bound state problem for hadrons

Publisher: name: arXiv
Year: 2011
Subjects: subject: General Physics (physics.gen-ph)
subject: FOS: Physical sciences

description: A second order extension of the QED Lagrangian (including boson-boson coupling) has been used to describe q\bar q hadrons. Assuming massless elementary fermions (quantons) this results in a finite theory without open parameters, which may be regarded as a fundamental description of the strong interaction. Two potentials are deduced, a boson-exchange potential and one, which can be identified with the known confinement potential in hadrons. This formalism has been applied the mesonic systems omega(782), Phi(1020), J/psi(3097) and Upsilon(9460), for which a good description is obtained. The most important results are: 1. The confinement of hadrons is not due to colour, but is a general property of relativistic bound states. 2. Massive quarks in the Standard Model (QCD) are understood as effective fermions with a mass given by the binding energy in the boson-exchange potential.

description: For the possible application to the cryogenically cooled low noise HEMT amplifier, this paper presents scattering parameter measurements of a HEMT chip at room and liquid nitrogen temperatures and in the 1-20 GHz frequency range. The measurement method which uses the well known TRL calibration technique will be fully discussed. S parameters and noise parameters measured at room temperature by means of this technique have been used to design a single stage low noise amplifier for the K band. Without any tuning this amplifier has an overall noise figure value of 1.6 dB with a 7 dB associated gain at 18 GHz which is in good agreements with predictions.

description: We develop modulation theory for undular bores (dispersive shock waves) in the framework of the Gardner, or extended Korteweg--de Vries, equation, which is a generic mathematical model for weakly nonlinear and weakly dispersive wave propagation, when effects of higher order nonlinearity become important. Using a reduced version of the finite-gap integration method we derive the Gardner-Whitham modulation system in a Riemann invariant form and show that it can be mapped onto the well-known modulation system for the Korteweg--de Vries equation. The transformation between the two counterpart modulation systems is, however, not invertible. As a result, the study of the resolution of an initial discontinuity for the Gardner equation reveals a rich phenomenology of solutions which, along with the KdV type simple undular bores, include nonlinear trigonometric bores, solibores, rarefaction waves and composite solutions representing various combinations of the above structures. We construct full parametric maps of such solutions for both signs of the cubic nonlinear term in the Gardner equation. Our classification is supported by numerical simulations.

We expound the theoretical framework that underlies the delicate statistical procedure illustrating its salient aspects. In particular, we show that the order of the two operations of sum and normalization used to combine the single waveforms so as to build the global PDF is a crucial point. We also illustrate how a consistency check able to test the correctness of the PDF-composing procedure should be designed.

description: The present paper proposes an exhaustive comparison between the two methods of extracting the nonlinear parameters of the NE72084 transistor. For this purpose, we have developed a continuous and pulsed automatized set up along with a fitting program that permits us to obtain the total nonlinear transistor model. Furthermore, a software program that permits us to extract the total linear equivalent circuit measuring the scattering parameters in the 2-8 GHz frequency band at several polarization points in order to obtain the quasi-static nonlinear model has been developed. Simulations taking into account low frequency dispersion permit comparisons between the model obtained from pulsed measurements and the quasi-static approach. Experimental measurements show the agreement of the two different models.
Muscle activity during functional tasks in pre-frail and frail individuals
Creators: name: Neubauer, Noelannah Alyse Adriannah
Publisher: name: University of British Columbia
Year: 2014

description: The ability to identify the progression of frailty is essential to mitigate physical impairments associated with aging. Previous studies have indicated that stages of frailty can be identified through bursts and gaps in electromyography (EMG) for an 8-hour day. The purpose of this study was to determine whether EMG and a specific functional task, or group of functional tasks is sensitive to classify middle-aged, non-frail, pre-frail, and frail older adults. Fifteen middle-aged (49 ± 5 years), and seventy-six older adults (77 ± 8 years) participated in this study. Older adults were categorized as non-frail (n= 49), pre-frail (n=20) and frail (n= 7) based-upon gait speed and modified frailty index score. Bursts and gaps were measured in the biceps brachii, triceps brachii, vastus lateralis, and biceps femoris bilaterally during nine functional tasks: (1) Standing-up from a chair; (2) a toilet; and (3) the floor; (4) Dressing and undressing a buttoned shirt; (5) Transferring laundry between washer and dryer; (6) Carrying laundry up stairs; (7) Eating soup; (8) Preparing a light meal; and (9) Loading, carrying and unloading groceries. Bursts were greater and gaps fewer in frail compared with middle-aged and non-frail. The variable that provided the best prediction of phenotype allocation was the fewer number of gaps in the upper limbs (Λ = 0.677, χ2 (9) = 33.746, p< 0.001), and greater mean burst amplitude in lower limbs during the chair, toilet, and floor tasks (Λ = 0.764, χ2 (9) = 23.310, p< 0.001); where 80.2% and 72.5% of the original grouped cases were correctly classified in this sample. When separated by sex, the number of gaps respectively, correctly classified 100% and 81.8% of males and females. Mean burst amplitude correctly classified 77.8% and 78.2% of males and females. Burst and gap characteristics indicate that EMG differs across stages of frailty and progression is best identified with mobility tasks of rising from a chair, toilet and floor.

description: A long-standing conjecture of Kelly states that every regular tournament on n vertices can be decomposed into (n-1)/2 edge-disjoint Hamilton cycles. We prove this conjecture for large n. In fact, we prove a far more general result, based on our recent concept of robust expansion and a new method for decomposing graphs. We show that every sufficiently large regular digraph G on n vertices whose degree is linear in n and which is a robust outexpander has a decomposition into edge-disjoint Hamilton cycles. This enables us to obtain numerous further results, e.g. as a special case we confirm a conjecture of Erdos on packing Hamilton cycles in random tournaments. As corollaries to the main result, we also obtain several results on packing Hamilton cycles in undirected graphs, giving e.g. the best known result on a conjecture of Nash-Williams. We also apply our result to solve a problem on the domination ratio of the Asymmetric Travelling Salesman problem, which was raised e.g. by Glover and Punnen as well as Alon, Gutin and Krivelevich.

description: Mass and spin are the only two parameters needed to completely characterize black holes in General Relativity. However, the interaction between black holes and their environment is where complexity lies, as the relevant physical processes occur over a large range of scales. That is particularly relevant in the case of super-massive black holes (SMBHs), hosted in galaxy centers, and surrounded by swirling gas and various generations of stars. These compete with the SMBH for gas consumption and affect both dynamics and thermodynamics of the gas itself. How the behavior of such fiery environment influence the angular momentum of the gas accreted onto SMBHs, and, hence, black-hole spins is uncertain. We explore the interaction between SMBHs and their environment via first 3D sub-parsec resolution simulations (ranging from 0.1 pc to 1 kpc scales) that study the evolution of the SMBH spin by including the effects of star formation, stellar feedback, radiative transfer, and metal pollution according to the proper stellar yields and lifetimes. This approach is crucial to investigate the impact of star formation processes and feedback effects on the angular momentum of the material that could accrete on the central hole. We find that star formation and feedback mechanisms can locally inject significant amounts of entropy in the surrounding medium, and impact on the inflow inclination angles and Eddington fractions. As a consequence, the resulting trends show upper-intermediate equilibrium values for the spin parameter, a, of about 0.6 - 0.9, corresponding to radiative efficiencies ε= 9% - 15%. These results suggest that star formation feedback taking place in the circum-nuclear disk during the in-fall cannot induce alone very strong chaotic trends in the gas flow, quite independently from the different numerical parameters.

Tools of mechanical impact on crop residues are various combines equipped with shredders and special trailed shredders. Effectiveness of strip-till technology in the cultivation of potatoes, the use of which has provided optimal conditions of water regime and nutrition due to the reduction of the soil surface temperature that guarantees higher yields, is confirmed.

description: Food production has historically been and remains an important and vital problem for mankind on a global scale. The level of food security is considered as the most important factor and determining criterion of the level of social life of any country, the viability of its economic structure and government in solving this problem, a special role belongs to animal husbandry, among which the leading place is meat cattle. The state of development of the regional market of livestock products and the issue of providing the population with physiologically necessary meat products were and remain the most pressing problems of the country. The mar-ket for livestock products, like any other market, forms links between producers and their consumers on the basis of supply, demand and mechanisms of market competition. Further development of the market of livestock products is one of the most important problems of the agricultural sector of the economy, which needs quality transformations that can ensure the efficient operation of the industry. The implementation of this task is asso-ciated with the definition of strategic guidelines for the development of the meat product subcomplex, in ac-cordance with which public policy and innovation and investment activities should be carried out.

It is shown that such a contribution has affected the shape of the differential cross section in the Coulomb-hadron interference region and in the dip region. On the basis of the new High-Energy General Structure (HEGS) model, the possible contributions of the hard pomeron are investigated. The predictions of the model at $8 \ $ TeV are discussed.

description: Die vorliegende Arbeit untersucht die subjektive Gesundheit, die Inanspruchnahme des Gesundheitssystems sowie das Erleben medizinischer Versorgung aus der Perspektive von Asylbewerber_innen. Dazu wurden von August bis November 2015 16 leitfadengestützte, teilweise dolmetscher_innenassistierte Interviews geführt, anonymisiert, transkribiert und inhaltsanalytisch ausgewertet. Es konnten insgesamt sechs relevante Kategorien der Erfahrungen in diesen Themenbereichen rekonstruiert werden. Die vier deduktiv erarbeiteten Kategorien beschreiben die Implikationen der subjektiven Gesundheit, die Zugangspfade und die Gewährungspraxis im Gesundheitssystem, die Erfahrungen in der medizinischen Versorgung selbst sowie die Rolle der sozialen Unterstützung und ihrer Akteur_innen. Außerdem konnten zwei induktive Kategorien identifiziert werden: die Zugangskommunikation und das Medizin- und Ärzt_innenbild der Befragten. Der Zugang zu medizinischer Versorgung stellt sich als umständlich und intransparent dar. Kommunikative Hürden treten in vielfältiger Weise auch und besonders vor dem eigentlichen Ärzt_innenkontakt auf. Asylbewerber_innen organisieren den voraussetzungsvollen Zugang zum Gesundheitssystem zu weiten Teilen selbst Die Ergebnissen reichern bestehende Modelle der Inanspruchnahme medizinischer Leistungen (Behavioral Model of Health Services Use) an und zeigen eine spezifische Anwendung auf die Situation von Asylbewerber_innen in Sachsen-Anhalt und Deutschland. Es lassen sich potentielle Ableitungen zur Förderung der Erreichbarkeit des medizinischen Systems, der Gesundheitskompetenz sowie der Patient_innenautonomie formulieren.

description: We study the relationship between local structural ordering and dynamical heterogeneities in a model glass-forming liquid, the Wahnstrom mixture. A novel cluster-based approach is used to detect local energy minimum polyhedral clusters and local crystalline environments. A structure-specific time correlation function is then devised to determine their temporal stability. For our system, the lifetime correlation function for icosahedral clusters decays far slower than for those of similarly sized but topologically distinct clusters. Upon cooling, the icosahedra form domains of increasing size and their lifetime increases with the size of the domains. Furthermore, these long-lived domains lower the mobility of neighboring particles. These structured domains show correlations with the slow regions of the dynamical heterogeneities that form on cooling towards the glass transition. Although icosahedral clusters with a particular composition and arrangement of large and small particles are structural elements of the crystal, we find that most icosahedral clusters lack such order in composition and arrangement and thus local crystalline ordering makes only a limited contribution to this process. Finally, we characterize the spatial correlation of the domains of icosahedra by two structural correlation lengths and compare them with the four-point dynamic correlation length. All the length scales increase upon cooling, but in different ways.

Learning from Complex Systems: On the Roles of Entropy and Fisher Information in Pairwise Isotropic Gaussian Markov Random Fields

description: Markov Random Field models are powerful tools for the study of complex systems. However, little is known about how the interactions between the elements of such systems are encoded, especially from an information-theoretic perspective. In this paper, our goal is to enlight the connection between Fisher information, Shannon entropy, information geometry and the behavior of complex systems modeled by isotropic pairwise Gaussian Markov random fields. We propose analytical expressions to compute local and global versions of these measures using Besag's pseudo-likelihood function, characterizing the system's behavior through its \emph{Fisher curve}, a parametric trajectory accross the information space that provides a geometric representation for the study of complex systems. Computational experiments show how the proposed tools can be useful in extrating relevant information from complex patterns. The obtained results quantify and support our main conclusion, which is: in terms of information, moving towards higher entropy states (A --> B) is different from moving towards lower entropy states (B --> A), since the \emph{Fisher curves} are not the same given a natural orientation (the direction of time).

Immunologische Parameter bei Langzeitüberlebenden mit Glioblastom

description: Das Glioblastom ist der häufigste und zugleich bösartigste aller Hirntumoren. Bei einer mittleren Überlebensdauer zwischen 14 und 15 Monaten und einer Langzeitüberlebensrate von nur drei bis fünf Prozent ist die Prognose schlecht. Nichtsdestotrotz existieren einige wenige Fälle, die diese Tumorerkrankung bis zu 20 Jahren überleben. Berichte und Studien über die sogenannten Langzeitüberlebenden sind rar. Vergleichsweise wenige Studien lassen vermuten, dass das Immunsystem bei der Pathogenese und Bewältigung des Glioblastoms eine entscheidende Rolle spielt und damit auch die Prognose beeinflusst. In dieser Arbeit wurde Tumorgewebe von 14 Langzeitüberlebenden auf die Expression einer kleinen Auswahl von Antigenen untersucht und die Ergebnisse mit Tumorgewebe von Patienten, die der durchschnittlichen Überlebensdauer entsprachen verglichen. Wir konnten feststellen, dass die Antigene CD 8 und CD 25 auf Lymphozyten im Tumorgewebe von Langzeitüberlebenden deutlich signifikant sowie CD 20 und CD 95 signifikant höher exprimiert wurden als im Tumorgewebe der Kurzzeitüberlebenden. Zudem fanden wir eine als unspezifisch zu wertende starke Positivität der Antikörper gegen CD 26 und CD 57 in beiden Gruppen. Bezüglich der bereits etablierten Prognosemarker IDH 1 und MGMT unterschieden sich beide Gruppe nicht. Somit kann eine Korrelation zwischen der Expression dieser Antigene und Langzeitüberleben angenommen werden. Weiter scheint unseren Ergebnissen zufolge nicht nur den T-Lymphozyten, sondern auch den B- Lymphozyten eine entscheidende Rolle bei der Immunpathogenese des Glioblastoms zuzukommen.

description: The characteristics of three-dimensional (3D) multilayer coplanar waveguide (CPW) lines incorporating a 90 o vertical interconnection structure have been investigated using a full wave analysis. Possible coupling effects between CPW lines in different layers have been taken into account, with results showing that such effects could be very strong if the adjacent CPW lines are too close. As the distance between the adjacent lines increases, the coupling effects become weak;  nevertheless it is not completely negligible for many practical applications. Equivalent circuits including such weak coupling effects which comprises of mixed lumped components and transmission lines have been developed. A good agreement with the full wave analysed results over ku, k and ka bands has been achieved. In addition to fundamental propagation mode, higher order mode effects have also been examined. The simulation results indicate that the second or third order modes might become dominant propagation mode at higher frequency depending upon the CPW structure and its layer distance.

description: Für diese Dissertation wurden 25 Patienten im posttraumatischen apallischen Syndrom daraufhin untersucht, welche Hirnstrukturen sich in einer frühzeitig nach Unfall durchgeführten MRT als pathologisch darstellten. Die Langzeitverläufe der Patienten wurden erhoben und auf Einflussfaktoren bezüglich der Letalität und des Behandlungsergebnisses untersucht. In allen Fällen lagen Ergebnisse über ein Jahr, in 19 der 25 Fälle darüber hinaus vor. Letztere Gruppe konnte im Durchschnitt 7 Jahre und 5 Monate nachverfolgt werden. Insgesamt verstarben sechs Patienten (24%). Drei Monate nach Trauma verblieben neun (36%), zwölf Monate nach Trauma fünf Patienten (20%) im apallischen Syndrom. Von diesen verbesserte sich ein Patient noch nach vier Jahren. Alle Patienten wiesen in der MRT eine beidseitige Läsion im Bereich des Mesencephalon auf. Die Wahrscheinlichkeit für apallische Patienten zu versterben war signifikant geringer, wenn ihr Alter zum Unfallzeitpunkt unter 30 Jahren lag, innerhalb der ersten 24 Stunden keine Strecksynergismen und/oder beidseitig weite und lichtstarre Pupillen auftraten oder die ursächliche Traumatisierung in einem PKW stattfand. Der Anteil der Patienten, die nach zwölf Monaten ein gutes Behandlungsergebnis erreichten, war signifikant jünger als die restliche Kohorte. Die Wahrscheinlichkeit für Patienten in einem apallischen Syndrom zu verbleiben war signifikant abhängig von der Dauer des Komas. Hierbei deutete eine Komalänge von unter zwölf Tagen auf eine höhere Erholungswahrscheinlichkeit hin. Kein Patient unserer Studie, der innerhalb dieser Zeitspanne erwachte, befand sich ein Jahr nach Trauma noch in einem apallischen Syndrom.
