title: Energetics and equal-time response of strongly-coupled fermions in one and two dimensions
Creators: name: Rammelmüller, Lukas

Subjects: subject: strongly correlated electron systems
subject: low-dimensional physics

description: Strongly interacting Fermi gases constitute a very challenging and interesting area within many-body physics and have received a tremendous amount of theoretical and experimental attention. Especially in the last decade, when it became possible to probe low- dimensional, ultracold atomic gases experimentally, many new approaches were developed to understand the physics of reduced dimensionality. In this work, we set out to characterize the ground-state of interacting Fermi gases in one and two spatial dimensions. We calculate quantities across a wide range of interaction strengths and particle numbers, in order to characterize the crossover from few- to many- body physics. Although numerous methods exist to treat aspects of the one-dimensional (1D) case analytically, there currently is no known method to extract results from two-dimensional (2D) systems in such a way. We therefore need to address this problem numerically and choose to treat the problem by means of Quantum Monte Carlo (QMC) methods. Specifically, we calculate quantities on the lattice, using an auxiliary field decomposition, closely related to methods typically used in lattice-QCD calculations. In the first part of this work, we introduce the physics of Fermi gases. Furthermore, we provide an overview of the necessary knowledge and definitions needed to understand this work. In the second chapter, the concept of stochastic integration is introduced. Starting at the basics of Monte Carlo integration, we arrive at the specific algorithms used in this work. Subsequently, we present results for the ground-state of 1D and 2D systems in chapters 3 and 4, respectively. We focus on equal-time density matrices as well as energetics in both cases. Finally, we conclude our work in the last chapter and point out possibilities to extend our research in the future.

description: We introduce the concept of Stieltjes integral of an operator-valued function with respect to the spectral measure associated with a normal operator. We give sufficient conditions for the existence of this integral and find bounds on its norm. The results obtained are applied to the Sylvester and Riccati operator equations. Assuming that the entry C is a normal operator, the spectrum of the entry A is separated from the spectrum of C, and D is a bounded operator, we obtain a representation for the strong solution X to the Sylvester equation XA-CX=D in the form of an operator Stieltjes integral with respect to the spectral measure of C. By using this result we then establish sufficient conditions for the existence of a strong solution to the operator Riccati equation YA-CY+YBY=D where B is another bounded operator.
The Analysis of Space-Time Structure in QCD Vacuum I: Localization vs Global Behavior in Local Observables and Dirac Eigenmodes

description: The structure of QCD vacuum can be studied from first principles using lattice-regularized theory. This line of research entered a qualitatively new phase recently, wherein the space-time structure (at least for some quantities) can be directly observed in configurations dominating the QCD path integral, i.e. without any subjective processing of typical configurations. This approach to QCD vacuum structure does not rely on any proposed picture of QCD vacuum but rather attempts to characterize this structure in a model-independent manner, so that a coherent physical picture of the vacuum can emerge when such unbiased numerical information accumulates to a sufficient degree. An important part of this program is to develop a set of suitable quantitative characteristics describing the space-time structure in a meaningful and physically relevant manner. One of the basic pertinent issues here is whether QCD vacuum dynamics can be understood in terms of localized vacuum objects, or whether such objects behave as inherently global entities. The first direct studies of vacuum structure strongly support the latter. In this paper, we develop a formal framework which allows to answer this question in a quantitative manner. We discuss in detail how to apply this approach to Dirac eigenmodes and to basic scalar and pseudoscalar composites of gauge fields (action density and topological charge density). The approach is illustrated numerically on overlap Dirac zeromodes and near-zeromodes. This illustrative data provides direct quantitative evidence supporting our earlier arguments for the global nature of QCD Dirac eigenmodes.

Cell and molecular biology in hereditary gingival fibromatois
Creators: name: Csiszar, Andrea
Publisher: name: University of British Columbia
Year: 2010

description: Gingival overgrowth, a potential side effect of medications i.e. nifedipine, cyclosporine, is also a characteristic feature of hereditary gingival fibromatosis (HGF). Autosomal dominant, non-syndromic HGF, the most common variant, has been localized to chromosomes 2p21 -p22 (HGFI) (Hart et al., 1998; Hart et al., 2000; Hart et al., 2002; Xiao et al., 2000), 5q13-q22 (HGF2) (Xiao et al., 2001) and 2p22.3-p23.3 (HGF3) (Ye et al., 2005), suggesting genetic heterogeneity. Interestingly, one of these mutations results in constitutive activation of the signaling molecule SOS-1, which is a key regulator of cell function and gene expression. Clinical observations suggest that HGF starts at the interdental papilla area from where it expands to other areas of gingiva by a process that may resemble gingival wound healing. Since the molecular changes in HGF are largely unknown, we compared the expression of cell surface (avβ6 integrin), intracellular (SOS-1 and CK19) and extracellular matrix molecules (procollagen, FN-EDA, FN-EDB, tenascin-C, decorin, biglycan, fibromodulin, lumican) and growth factors (TGF-β and CTGF) involved in wound healing, in healthy and HGF marginal gingiva by immunohistochemical staining. We also analyzed the localization of these molecules in healthy interdental papilla. Results showed that the molecular phenotype of healthy marginal gingiva differs from that of healthy interdental papilla. Therefore, we compared the expression of target molecules in the same tissue locations (marginal gingiva) in healthy and HGF subjects. Expression of CK19 and avβ6 integrin was induced by epithelial cells in HGF samples, but they were not in healthy marginal gingiva. Furthermore, epithelial cells in HGF showed increased expression of biglycan, fibromodulin, lumican, TGF-β₁,₂,₃, CTGF and SOS-1 compared to healthy tissue. Expression of biglycan, lumican, procollagen, FN-EDB and tenascin-C were also upregulated in the extracellular matrix in HGF. Compared to healthy tissues, cell associated staining for biglycan, fibromodulin, lumican, procollagen, FN-EDB, TGF-β₁,₂,₃, and SOS-1 was increased in HGF. The latter three molecules showed also spatiotemporally increased expression in gingival experimental wounds. The repertoire of molecules that are expressed in HGF in marginal gingiva is different from healthy marginal gingiva, but shows similarities to gingival wounds and healthy interdental papilla.

description: We consider black hole formation in failed supernovae when a dense circumstellar medium (CSM) is present around the massive star progenitor. By utilizing radiation hydrodynamical simulations, we calculate the mass ejection of blue supergiants and Wolf-Rayet stars in the collapsing phase and the radiative shock occurring between the ejecta and the ambient CSM. We find that the resultant emission is redder and dimmer than normal supernovae (bolometric luminosity of $\sim 10^{40}-10^{41}\ {\rm erg\ s^{-1}}$, effective temperature of $\sim 5\times 10^3$ K, and timescale of 10-100 days) and shows a characteristic power-law decay, which may comprise a fraction of intermediate luminosity red transients (ILRTs) including AT 2017be. In addition to searching for the progenitor star in the archival data, we encourage X-ray follow-up observations of such ILRTs $\sim$ 1-10 yr after the collapse, targeting the fallback accretion disk.

description: The pion form factor is computed using quenched twisted mass QCD and the GMRES-DR matrix inverter. The momentum averaging procedure of Frezzotti and Rossi is used to remove leading lattice spacing artifacts, and numerical results for the form factor show the expected improvement with respect to the standard Wilson action. Although some matrix inverters are known to fail when applied to twisted mass QCD, GMRES-DR is found to be a viable and powerful option. Results obtained for the pion form factor are consistent with the published results from other O(a) improved actions and are also consistent with the available experimental data.

description: We show that a totally dissipative system has all nonsingular systems as factors, but that this is no longer true when the factor maps are required to be finitary. In particular, if a nonsingular Bernoulli shift satisfies the Doeblin condition, and has a limiting marginal distribution p, then it cannot have, as a finitary factor, an independent and identically distributed (iid) system of entropy larger than H(p); on the other hand, we show that iid systems with entropy strictly lower than H(p) can be obtained as finitary factors of these Bernoulli shifts, extending Keane and Smorodinsky's finitary version of Sinai's factor theorem to the nonsingular setting. As a consequence of our results we also obtain that every transitive twice continuously differentiable Anosov diffeomorphism on a compact manifold, endowed with volume measure, has iid factors, and if the factor is required to be finitary, then the iid factor cannot have Kolmogorov-Sinai entropy greater than the measure-theoretic entropy of a Sinai-Ruelle-Bowen measure associated with the Anosov diffeomorphism.

description: A high-performance wide-angle refractive index sensor based on a simple onedimensional (1D) metallic deep nanogroove array with high aspect ratio is experimentally fabricated and demonstrated. The 1D deep groove array is featured by the excitation of magnetic plasmon (MP), referring to an effective coupling of incident electromagnetic waves with a strong magnetic response induced inside the deep grooves. Utilizing the MP resonances that are extremely sensitive to the surrounding dielectric medium, we successfully achieve a refractive index sensitivity (RIS) up to $\sim$1300 nm/RIU, which is higher than that of most experimentally designed plasmonic sensors in infrared region. Importantly, benefiting from angle-independent MP resonances with strong confinement of magnetic field inside the deep grooves and strong electric field localization at the groove openings, we demonstrate wide-angle sensing capability valid in a broadband infrared region with an excellent linear dependence on the change of refractive index. Such a MP-based sensor, together with its simple 1D flat nature and ease of fabrication, has great potential for practical design of high sensitive, cost-effective and compact sensing devices.

description: The distribution of rents between the successive stages in the food chain has been of great interest both to academicians and policy makers. Notwithstanding the extensive literature devoted to this issue, our understanding of the vertically related nature of the food chain and factors affecting bargaining power of various agents is still limited. This paper tries to fill this gap at least in part. The specific example that we use comes from dairy sector in Poland. Based on a unique micro-survey data, we provide some evidence documenting farmers’ position vis-à-vis processing industry and input suppliers. Interestingly, the picture we get is rather inconsistent with a popular opinion arguing that farmers are being “exploited” by other stages in the food chain.
title: Semantics and statistics for automated image annotation
Creators: name: Llorente Coto, Ainhoa
Publisher: name: The Open University
Year: 2010

description: Automated image annotation consists of a number of techniques that aim to find the correlation between words and image features such as colour, shape, and texture to provide correct annotation words to images. In particular, approaches based on Bayesian theory use machine-learning techniques to learn statistical models from a training set of pre-annotated images and apply them to generate annotations for unseen images.

 The focus of this thesis lies in demonstrating that an approach, which goes beyond learning the statistical correlation between words and visual features and also exploits information about the actual semantics of the words used in the annotation process, is able to improve the performance of probabilistic annotation systems. Specifically, I present three experiments. Firstly, I introduce a novel approach that automatically refines the annotation words generated by a non-parametric density estimation model using semantic relatedness measures. Initially, I consider semantic measures based on co-occurrence of words in the training set. However, this approach can exhibit limitations, as its performance depends on the quality and coverage provided by the training data. For this reason, I devise an alternative solution that combines semantic measures based on knowledge sources, such as WordNet and Wikipedia, with word co-occurrence in the training set and on the web, to achieve statistically significant results over the baseline. Secondly, I investigate the effect of using semantic measures inside an evaluation measure that computes the performance of an automated image annotation system, whose annotation words adopt the hierarchical structure of an ontology. This is the case of the ImageCLEF2009 collection. Finally, I propose a Markov Random Field that exploits the semantic context dependencies of the image. The best result obtains a mean average precision of 0.32, which is consistent with the state-of-the-art in automated image annotation for the Corel 5k dataset.

description: Golay complementary matrices (GCM) have recently drawn considerable attentions owing to its potential applications in omnidirectional precoding. In this paper we generalize the GCM to multi-dimensional Golay complementary arrays (GCA) and propose new constructions of GCA pairs and GCA quads. These constructions are facilitated by introducing a set of identities over a commutative ring. We prove that a quaternary GCA pair is feasible if the product of the array sizes in all dimensions is a quaternary Golay number with an additional constraint on the factorization of the product. For the binary GCM quads, we conjecture that the feasible sizes are arbitrary, and verify for sizes within 78 $\times$ 78 and other less densely distributed sizes. For the quaternary GCM quads, all the positive integers within 1000 can be covered for the size in one dimension.

We identify that the early dark energy (EDE) (non-negligible around matter-radiation equality) scenario can remain compatible with the FIRAS result, while lifting the Hubble constant $H_0$. We perform Monte Carlo Markov chain analysis to confirm our observations. We also present an $α$-attractor Anti-de Sitter (AdS) model of EDE, in which the AdS depth is consistently varied in the Monte Carlo Markov chain analysis. We found that our datasets weakly hinted the existence of an AdS phase near recombination with $H_0\sim 73$km/s/Mpc at 1$σ$ region in the best-fit model.

description: We suggest a new random model for links based on meander diagrams and graphs. We then prove that trivial links appear with vanishing probability in this model, no link $L$ is obtained with probability 1, and there is a lower bound for the number of non-isotopic knots obtained for a fixed number of crossings. A random meander diagram is obtained through matching pairs of parentheses, a well-studied problem in combinatorics. Hence tools from combinatorics can be used to investigate properties of random links in this model, and, moreover, of the respective 3-manifolds that are link complements in 3-sphere. We use this for exploring geometric properties of a link complement. Specifically, we give expected twist number of a link diagram and use it to bound expected hyperbolic and simplicial volume of random links. The tools from combinatorics that we use include Catalan and Narayana numbers, and Zeilberger's algorithm.

description: If an exact $μ\leftrightarrow τ$ symmetry is the explanation of the maximal atmospheric neutrino mixing angle, it has interesting implications for origin of matter via leptogenesis in models where small neutrino masses arise via the seesaw mechanism. For seesaw models with two right handed neutrinos $(N_μ, N_τ)$, lepton asymmetry vanishes in the exact $μ\leftrightarrow τ$ symmetric limit, even though there are nonvanishing Majorana phases in the neutrino mixing matrix. On the other hand, for three right handed neutrino models, lepton asymmetry nonzero and is given directly by the solar mass difference square. We also find an upper bound on the lightest neutrino mass.

description: The notion of expansivity and its generalizations (measure expansive, measure positively expansive, continuum-wise expansive, countably-expansive) are well known for deterministic systems and can be a useful property for studying significant type of behavior, such as chaotic one. This study aims to extend these notions into a random context and prove a relationship between relative positive entropy and random expansive measures and apply it to show that if a random dynamical system has positive relative topological entropy then the $w$-stable classes have zero measure for the conditional measures. We also prove that there exists a probability measure that is both invariant and expansive. Moreover, we obtain a relation between the notions of random expansive measures and random countably-expansive systems.

Unnoticed unwanted thoughts : what you don’t (meta)-know can hurt you
Creators: name: Fishman, Daniel J. F.

description: Research on thought suppression has generally assumed that undesired thoughts can be either conscious or unconscious, and has posited that some interplay between unconscious and conscious thoughts is responsible for the difficulty people have in suppressing unwanted thoughts (Wegner, 1997). This dichotomy ignores the possibility suggested by work on "meta-awareness" (the awareness of the contents of conscious thought) that some of our thoughts may be consciously experienced without our being aware that we are having them. This paper describes two studies which investigate this phenomenon using a combination of probe-reported and self-reported unwanted thoughts. Participants were asked to try not to think about a previous romantic relationship while reading and while sitting quietly with no other task; some participants were also placed in either a high or low cognitive load condition. The data showed that participants sometimes experienced “unnoticed unwanted thoughts”--thoughts of their previous relationship which they experienced but were not aware of experiencing. These unnoticed unwanted thoughts were predictive of participants’ scores on a test of the reading material. High cognitive load was found to increase the occurrence of unnoticed unwanted thoughts, but not the occurrence of unwanted thoughts that participants noticed themselves.

description: Contributor's aunt was brought up by Mr and Mrs William Franklin, originally from Norfolk. William worked for a removal company in London, working closely with horses. Believed he organised casual labour for the company. Volunteered in his 40s, he had the rank of sergeant and was in charge of a stable. Whilst looking after a horse that was suffering terribly from shell shock, he refused an order to saddle up the horse from a senior officer who wanted to ride the animal for recreation. William was subsequently court martialled, demoted to private and dispatched to a machine gun unit at the front. During a raid he was gassed and though he survived the war never fully recovered.

As a young girl the contributor remembers him as a sick man, quite disabled by his injury. He died in the 1940s. She also remembered that he received letters from his fellow troops commending his stance regarding the horse.

description: In any agricultural activity, there are multiple risks. They have an impact on the results achieved by the farms. In the process of risk management it is necessary to identify risks and to use appropriate methods of risk reduction. One of the best instruments for risk protection in agriculture is insurance. Polish legislation provides a number of opportunities to uses of insurance. The State requires traders to insure property, crops, vehicles. Besides, it is possible also to use the voluntary insurance. The surveys show, however, that the use of insurance is insufficient.
Information Swimmer: A Novel Mechanism of Self-propulsion

description: We study an information-based mechanism of self-propulsion in noisy environment. An information swimmer maintains directional motion by periodically measuring its velocity and accordingly adjusting its friction coefficient. Assuming that the measurement and adjustment are reversible and hence cause no energy dissipation, an information swimmer may move without external energy input. There is however no violation of the second law of thermodynamics, because the information entropy stored in the memory of swimmer increases monotonically. By optimizing its control parameters, the swimmer can achieve a steady velocity that is comparable to the root-mean-square velocity of an analogous Brownian particle. We also define a swimming efficiency in terms of information entropy production rate, and find that in equilibrium media with white noises, information swimmers are generally less efficient than Brownian particles driven by constant forces. For colored noises with long correlation times, the frequency of measurement can be greatly reduced without affecting the efficiency of information swimmers.

description: The aim of the study was to compare the resources of production factors, the relationship between them and their effectiveness in farms of various economic size. Also, the intensity and the costs of production and the share of the balance of subsidies and taxes on income from the family farm were analyzed. Everything was based on information from the years 2010-2013 collected by the FADN. In years 2010-2013 the bigger the farm, it was characterized by higher productivity of land, labor and capital (with the exception of economically very large farms, in which the productivity of land and labor were lower than in large farms). With the increase of economic size profitability of the grounds increased (but economically large farms were slightly lower than the average large, the lowest – in very large) and the profitability of assets (the exception were very large farmswhere it was the lowest). Income higher than the average net wage in the national economy gained farms who earned more than 25 thousand euro SO, the highest were in very large farms. High profitability of farm labor of very large farms was the result of an unjustified, more than 115%, of the balance current subsidies and taxes to farm net income. On the farms of the other economic size classes – the larger economically the farm was, the less characterized by the participation of the balance current subsidies and taxes to farm net income.

description: We study independent long-range percolation on $\mathbb{Z}^d$ where the vertices $x$ and $y$ are connected with probability $1-e^{-β\|x-y\|^{-d-α}}$ for $α> 0$. Provided the critical exponents $δ$ and $2-η$ defined by $δ= \lim_{n\to \infty} \frac{-\log(n)}{\log\left(\mathbb{P}_{β_c}\left(|K_0|\geq n\right)\right)}$ and $2-η= \lim_{x \to \infty} \frac{\log\left(\mathbb{P}_{β_c}\left(0\leftrightarrow x\right)\right)}{\log(\|x\|)} + d$ exist, where $K_0$ is the cluster containing the origin, we show that
 \begin{equation*}
 δ\geq \frac{d+(α\wedge 1)}{d-(α\wedge 1)} \ \text{ and } \ 2-η\geq α\wedge 1 \text.
 \end{equation*}
 The lower bound on $δ$ is believed to be sharp for $d = 1, α\in \left[\frac{1}{3},1\right)$ and for $d = 2, α\in \left[\frac{2}{3},1\right]$, whereas the lower bound on $2-η$ is sharp for $d=1, α\in (0,1)$, and for $α\in \left(0,1\right]$ for $d>1$, and is not believed to be sharp otherwise. Our main tool is a connection between the critical exponents and the isoperimetry of cubes inside $\mathbb{Z}^d$.

description: This paper identifies and examines the competitive position of European Union member states in foreign trade in agri-food products in 2004, 2009 and 2014. The survey is significant because foreign trade is the greatest and most important part of international economic relations. An analysis was carried out based upon indicators of the position in international goods exchange as follows: Revealed Comparative Advantage Index (RCA), export-import coverage ratio (Lafaya) and index of intra-industry trade (Grubela-Lloyda). The paper used data from EUROSTAT. The survey showed that in the examined years the following countries gained the highest competitive position among new member states of EU in foreign trade in agri-food products: Lithuania, Bulgaria, Poland and Latvia. Among the countries of the “old 15” member states, Holland was the leader. / Synopsis. Celem opracowania jest ocena pozycji konkurencyjnej państw członkowskich UE w handlu zagranicznym produktami rolno-spożywczymi w latach 2004, 2009 i 2014. Znaczenie tych badań wynika z faktu, że handel zagraniczny stanowi największą i najważniejszą część międzynarodowych stosunków gospodarczych. Analizę przeprowadzono w oparciu o następujące wskaźniki pozycji w międzynarodowej wymianie towarowej: indeks relatywnej komparatywnej przewagi eksportu (RCA), wskaźnik pokrycia importu eksportem (Lafaya) oraz wskaźnik handlu wewnątrzgałęziowego (Grubela-Lloyda). W pracy wykorzystano dane EUROSTAT. Przeprowadzone badania wykazały, że w badanych latach najwyższą pozycję konkurencyjną wśród nowych państw członkowskich UE w handlu zagranicznym produktami rolno-spożywczymi osiągała Litwa, Bułgaria, Polska i Łotwa. Spośród państw „starej 15” zdecydowanym liderem okazała się Holandia.

description: The aim of the study was to assess the possibility of achieving the benefits of portfolio diversification by investing in commodities classified into three groups: energy, metals and agricultural products. There are analyzed investment portfolios consisting of different assets, including direct ways of investing in commodities. On the basis of empirical data (daily prices of assets) rates of return, correlations and standard deviations were calculated for separate portfolios. The results revealed that a portfolio consisting of metal or contains this asset class brings higher income. / Synopsis. Celem pracy była ocena możliwości osiągnięcia korzyści z dywersyfikacji portfela za pomocą inwestowania w towary zaliczonych do trzech grup: surowców energetycznych, metali i rolnych. Analizowano portfele inwestycyjne o różnym składzie, wykorzystujące bezpośrednie formy inwestowania w towary. Na podstawie danych empirycznych (dziennych cen towarów) wyznaczano stopy zwrotu, korelacje i odchylenia standardowe dla poszczególnych portfeli. Uzyskane wyniki pozwoliły stwierdzić, że portfel składający się z metali, albo zawierający tę klasę aktywów przynosi wyższe dochody niż portfel zawierający w swym składzie np. towary rolne.
