description: We give a description of definable sets $P=(p_1,..., p_m)$ in a free non-abelian group $F$ and in a torsion-free non-elementary hyperbolic group $G$ that follows from our work on the Tarski problems. This answers Malcev's question for $F$. As a corollary we show that proper non-cyclic subgroups of $F$ and $G$ are not definable and prove Bestvina and Feighn's result that definable subsets $P=(p)$ in a free group are either negligible or co-negligible in their terminology.

"Western world's apart?" A comparison of patient information websites on depression in Canada, the United States and England
Creators: name: Keay, Aimee Lee
Publisher: name: University of British Columbia
Year: 2013

description: Healthcare information differs among the United States, Canada and England. Through a critical discourse analysis of fifteen websites on depression from these countries, this thesis reveals how linguistic differences and differences in the websites’ use of visual features persuade readers of the merits of different treatments. The analysis reveals that the trends are complex. However, England’s websites lean more towards talking therapy, the United States’ websites emphasize pharmaceutical intervention, and Canadian websites endorse the use of antidepressants where they mention treatment. These findings are illustrated through a comparison of vocabulary, grammatical, visual and ordering features (building from Fairclough’s 1989 framework). This thesis also reveals that patients from the United States, Canada and England are portrayed as in possession of differing levels of importance in the treatment-decision-making process with physicians. Of particular significance is the Canadian websites’ portrayal of patient deferral to expert physicians. By frequently referencing “your doctor,” using marked grammar for healthcare experts, and providing a reader with limited information on treatment options, Canada’s websites assert a traditional biomedical model of power relations. The patient is secondary to the physician. The United States’ privatized healthcare system indicates that websites from the United States would portray patient input as especially significant. However, it is England’s websites that suggest a high level of patient influence. Stressing patient involvement on England’s websites is perhaps indicative of the NHS’s 2012 constitution, which emphasizes that decision-making should be based on a model of concordance not compliance (Segal 2007). These findings highlight how the different healthcare models of each country might affect the information provided to patients. Above all, this research raises questions about the role of patient information websites, and about the different discursive strategies that subtly persuade a reader to view depression, treatment and their input in decision-making differently. England, United States and Canada all make use of the DSM IV-TR diagnostic criteria and operate under a biomedical model of medicine, but these websites suggest that potentially depressed patients are approached differently in each of these countries.

description: We report a theoretical study of the many-body effects of electron-electron interaction on the ground-state and spectral properties of double-layer graphene. Using a projector-based renormalization method we show that if a finite voltage difference is applied between the graphene layers electron-hole pairs can be formed and---at very low temperatures---an excitonic instability might emerge in a double-layer graphene structure. The single-particle spectral function near the Fermi surface exhibits a prominent quasiparticle peak, different from neutral (undoped) graphene bilayers. Away from the Fermi surface, we find that the charge carriers strongly interact with plasmons, thereby giving rise to a broad plasmaron peak in the angle-resolved photoemission spectrum.

description: We investigate bistability and memory effects in a molecular junction weakly coupled to metallic leads with the latter being subject to an adiabatic periodic change of the bias voltage. The system is described by a simple Anderson-Holstein model and its dynamics is calculated via a master equation approach. The controlled electrical switching between the many-body states of the system is achieved due to polaron shift and Franck-Condon blockade in the presence of strong electron-vibron interaction. Particular emphasis is given to the role played by the excited vibronic states in the bistability and hysteretic switching dynamics as a function of the voltage sweeping rates. In general, both the occupation probabilities of the vibronic states and the associated vibron energy show hysteretic behaviour for driving frequencies in a range set by the minimum and maximum lifetimes of the system. The consequences on the transport properties for various driving frequencies and in the limit of DC-bias are also investigated.

description: This paper deals with different images of Black minorities in
Argentinian Literature during XIX th. century. At first, Afrodescendants numbered almost 25 % of the population. However, in comparison with other ethnic groups, such as the "gauchos",there are not literary works mainly concerned with Afroargentinian people. They only appear as secondary characters and they are reduced to one or two common places: the loyal servant o the brave soldier, for instance.
Ideological motivs could explain this absence. In fact, Black people
were exluded from a political agenda created by criollist
intellectuals from the historical origins of the Nation.

description: Crystallographic and spin polarized transport properties of (100) textured and (100) epitaxial Fe/MgO/Fe magnetic tunnel junctions are compared. Strong similarities in the transport properties show that structural coherence and magnetic quality at the 25 nm grain scale in textured junctions are sufficient to issue signatures of the spin polarized transport specific to a single crystal junction. This demonstrates that the lateral coherence of the Bloch tunneling wave function is identically limited in both systems. Our analysis leads to model the textured tunnel junction as a juxtaposition of nanometer sized single crystal junctions, placed in parallel.

description: Slavery, which plaid a significant role in several ancient civilizations around the world, was supported by philosophers, theologians and popes. Even if its importance has been underestimated, the presence of black women and men is stated from the first expeditions to the River Plate (many times, by means of illegal traffic). Led by bishop Vitoria, that traffic increased since the late 16th century. Black women were often sexually exploited but, instead of paying attention to their problems, much of the literature has ignored them or has created an archetypal woman, characterized by beauty, sensuality and eroticism. With some exceptions, this image remains in our days.

description: In economic systems, the mix of products that countries make or export has been shown to be a strong leading indicator of economic growth. Hence, methods to characterize and predict the structure of the network connecting countries to the products that they export are relevant for understanding the dynamics of economic development. Here we study the presence and absence of industries at the global and national levels and show that these networks are significantly nested. This means that the less filled rows and columns of these networks' adjacency matrices tend to be subsets of the fuller rows and columns. Moreover, we show that nestedness remains relatively stable as the matrices become more filled over time and that this occurs because of a bias for industries that deviate from the networks' nestedness to disappear, and a bias for the missing industries that reduce nestedness to appear. This makes the appearance and disappearance of individual industries in each location predictable. We interpret the high level of nestedness observed in these networks in the context of the neutral model of development introduced by Hidalgo and Hausmann (2009). We show that, for the observed fills, the model can reproduce the high level of nestedness observed in these networks only when we assume a high level of heterogeneity in the distribution of capabilities available in countries and required by products. In the context of the neutral model, this implies that the high level of nestedness observed in these economic networks emerges as a combination of both, the complementarity of inputs and heterogeneity in the number of capabilities available in countries and required by products. The stability of nestedness in industrial ecosystems, and the predictability implied by it, demonstrates the importance of the study of network properties in the evolution of economic networks.

Personality traits, motivation, and the making of modern identity
Creators: name: Dunlop, William Lewis
Publisher: name: University of British Columbia
Year: 2013

description: What is the nature of personhood? How is identity best understood? In this dissertation, these questions are explored. Drawing upon a conception of personality in which behavioral traits, goal motivation, and identities are recognized as equal and complementary partners, two proposals are considered. First, it is argued that insights into many psychological phenomena can be enhanced through tandem consideration of the aforementioned personological elements. Second, it is argued that personal identity is manifest within both narrative and non-narrative (i.e., paradigmatic) forms. Support for the first proposal is garnered over the course of three empirical studies. In each of these studies—which consider context variability in the manifestation of personality attributes (i.e., self-concept differentiation), the interplay between the meta-concepts of agency and communion in moral motivation, and the relation between personality and culture, respectively—the predictive ability of traits, goals, and identities is examined. Considerable gains in predictive power are made through consideration of these elements of personality. Support for the second proposal is garnered through the undertaking of the third study, wherein a method for assessing personal identity in its narrative and paradigmatic forms is adopted and applied to a cross-cultural examination of personality. The current endeavor thus aims to apply a necessary corrective to the field of personality psychology (wherein personality and personality traits are often equated) and developmental psychology (wherein identity has increasingly come to be construed solely in narrative terms).

description: In one-dimensional real and complex dynamics, a map whose post-singular (or post-critical) set is bounded and uniformly repelling is often called a Misiurewicz map. In results hitherto, perturbing a Misiurewicz map is likely to give a non-hyperbolic map, as per Jakobson's Theorem for unimodal interval maps. This is despite genericity of hyperbolic parameters (at least in the interval setting). We show the contrary holds in the complex exponential family $z \mapsto λ\exp(z)$: Misiurewicz maps are Lebesgue density points for hyperbolic parameters. As a by-product, we also show that Lyapunov exponents almost never exist for exponential Misiurewicz maps. The lower Lyapunov exponent is negative infinity almost everywhere. The upper Lyapunov exponent is non-negative and depends on the choice of metric.

description: Principles of monitoring non-Markovian open quantum systems are analyzed. We use the field representation of the environment (Gardiner and Collet, 1985) for the separation of its memory and detector part, respectively. We claim the system-plus-memory compound becomes Markovian, the detector part is tractable by standard Markovian monitoring. Because of non-Markovianity, only the mixed state of the system can be predicted, the pure state of the system can be retrodicted. We present the corresponding non-Markovian stochastic Schrödinger equation.

description: We study charmed and strange baryon resonances that are generated dynamically by a unitary baryon-meson coupled-channel model which incorporates heavy-quark spin symmetry. This is accomplished by extending the SU(3) Weinberg-Tomozawa chiral Lagrangian to SU(8) spin-flavor symmetry plus a suitable symmetry breaking. The model produces resonances with negative parity from s-wave interaction of pseudoscalar and vector mesons with $1/2^+$ and $3/2^+$ baryons. Resonances in all the isospin, spin, and strange sectors with one, two, and three charm units are studied. Our results are compared with experimental data from several facilities, such as the CLEO, Belle or BaBar Collaborations, as well as with other theoretical models. Some of our dynamically generated states can be readily assigned to resonances found experimentally, while others do not have a straightforward identification and require the compilation of more data and also a refinement of the model. In particular, we identify the $Ξ_c(2790)$ and $Ξ_c(2815)$ resonances as possible candidates for a heavy-quark spin symmetry doublet.

description: Type Ia supernovae (SNe Ia) play important roles in our study of the expansion and acceleration of the Universe, but because we do not know the exact nature or natures of the progenitors, there is a systematic uncertainty that must be resolved if SNe Ia are to become more precise cosmic probes. No progenitor system has ever been identified either in the pre- or post-explosion images of a Ia event. There have been recent claims for and against the detection of ex-companion stars in several SNe Ia remnants. These studies, however, usually ignore the angular momentum gain of the progenitor WD, which leads to a spin-up phase and a subsequent spin-down phase before explosion. For spin-down timescales greater than 10^5 years, the donor star could be too dim to detect by the time of explosion. Here we revisit the current limits on ex-companion stars to SNR 0509-67.5, a 400 year old remnant in the Large Magellanic Cloud (LMC). If the effects of possible angular momentum gain on the WD are included, a wide range of single-degenerate progenitor models are allowed for this remnant. We demonstrate that the current absence of evidence for ex-companion stars in this remnant, as well as other SNe Ia remnants, does not necessarily provide the evidence of absence for ex-companions. We discuss potential ways to identify such ex-companion stars through deep imaging observations.

description: In semiconductor-superconductor hybrid structures a topological phase transition is expected as a function of chemical potential or magnetic field strength. We show that signatures of this transition can be observed in nonlinear Coulomb blockade transport through a ring shaped structure. In particular, for a fixed electron parity of the ring, the flux periodicity of the neutral excitation spectrum changes from the usual h/2e periodicity to a characteristic h/e periodicity when tuning the system from the topologically trivial to the nontrivial phase. We relate the h/e periodicity to the recently predicted 4πperiodicity of the Josephson current across a junction formed by two topological superconductors.

description: Off-farm income—such as pensions, investment income, or wages and salary from an off-farm job—is an important source of total income for U.S. farm households. In 2019, 96 percent of farm households derived some income from off-farm sources. On average, off-farm income contributed 82 percent of total income, or $101,638, for all family farms in 2019. Smaller farms tend to rely more on off-farm income than larger farms. On average, small family farms, those with an annual gross cash farm income (GCFI) under $350,000, derived more than half of their total household income from off-farm income in 2019. By comparison, on average, very large farms, those with a GCFI of $5 million or more, earned 7 percent of their total income from off-farm sources that year. However, those are averages, and some households operating small farms rely primarily on farm income, while some households operating larger farms rely on income from off-farm sources.
Synthesis and solubility of arsenic tri-sulfide and sodium arsenic oxy-sulfide complexes in alkaline sulfide solutions
Creators: name: Li, Wen
Publisher: name: University of British Columbia
Year: 2013

description: Alkaline sulfide leaching (ASL) at approximately 100 ºC has been used to selectively extract arsenic and antimony from enargite and tetrahedrite concentrates. Sodium thio-arsenate has been postulated to crystallize from alkaline sulfide leaching solutions upon cooling. However, literature data on the solubility of sodium thio-arsenate as well as proof of its crystallization from ASL solutions is scant. In this thesis, the solubility of leach-produced and synthetic sodium thio-arsenate is studied. To determine arsenic solubility in ASL solutions, sodium thio-arsenate and sodium arsenic oxide sulfide complexes are synthesized by various means and characterized by EDX, QXRD, and ICP. The synthesis of amorphous As₂S₃, sodium arsenic oxy-sulfide complexes, and sodium thio-arsenate is first presented. For amorphous As₂S₃ synthesis, the effect of concentration of sodium sulfide (0.1 M) and hydrochloric acid (1 M), temperature (40 ~ 60 ºC), and aging time (48 hours) was optimized. The solubility of synthetic sodium arsenic oxy-sulfide complexes and sodium thio-arsenate in ASL solutions increases significantly as temperature is increased to 95 ºC. More importantly, the solubility of sodium thio-arsenate at certain temperatures is significantly affected by the concentration of sodium hydroxide and sulfide in solution. Due to the common ion effect, if NaOH and HS- concentrations are very high, the solubility of sodium thio-arsenate decreases. Enargite leaching tests were done to characterize the precipitate that occurred upon cooling and to verify the arsenic saturation point, which should be between 38.5 ~ 58 g/L (0.51 M ~ 0.78 M) As depending on the NaOH and HS- concentration. Comparison with solubility experiments of pure sodium thio-arsenate shows that arsenic solubility in ASL solutions is supersaturated. However, direct comparison of saturation in ASL solutions and the solubility as obtained by the synthetic solutions/crystallites prepared here is not possible given the complex nature of the ASL crystallites that appear not to contain the often discussed “sodium thio-arsenate”.

description: Finite stochastic Markov models play a major role for modelling biochemical pathways. Such models are a coarse-grained description of the underlying microscopic dynamics and can be considered mesoscopic. The level of coarse-graining is to a certain extend arbitrary since it depends on the resolution of accomodating measurements. Here, we present a way to simplify such stochastic descriptions, which preserves both the meso-micro and the meso-macro connection. The former is achieved by demanding locality, the latter by considering cycles on the network of states. Using single- and multicycle examples we demonstrate how our new method preserves fluctuations of observables much better than naïve approaches.

description: The International Database on Longevity (IDL) (www.supercentenarians.org) is a  comprehensive resource that provides extensive information on validated data on deceased semi- and supercentenarians (aged 105-109 and 110+, respectively). The main goal of the IDL is to meticulously gather and curate data that undergoes a rigorous age validation process. This compilation of information serves as a valuable resource for researchers delving into the limits of human longevity and exploring mortality risks within the oldest age groups. By ensuring the accuracy and reliability of the data, the IDL provides researchers with a robust foundation for their investigations in these areas.

Chow-Kuenneth decomposition for 3- and 4-folds fibred by varieties with small Chow group of zero-cycles

description: Let $k$ be a field and let $Ω$ be a universal domain over $k$. Let $f:X \r S$ be a dominant morphism defined over $k$ from a smooth projective variety $X$ to a smooth projective variety $S$ of dimension $\leq 2$ such that the general fibre of $f_Ω$ has trivial Chow group of zero-cycles. For example, $X$ could be the total space of a two-dimensional family of varieties whose general member is rationally connected. Suppose that $X$ has dimension $\leq 4$. Then we prove that $X$ has a self-dual Murre decomposition, i.e. that $X$ has a self-dual Chow--Kuenneth decomposition which satisfies Murre's conjectures (B) and (D). Moreover we prove that the motivic Lefschetz conjecture holds for $X$ and hence so does the Lefschetz standard conjecture. We also give new examples of threefolds of general type which are Kimura finite-dimensional, new examples of fourfolds of general type having a self-dual Murre decomposition, as well as new examples of varieties with finite degree three unramified cohomology.

description: The mesoscopic spin system formed by the 10E4-10E6 nuclear spins in a semiconductor quantum dot offers a unique setting for the study of many-body spin physics in the condensed matter. The dynamics of this system and its coupling to electron spins is fundamentally different from its bulk counter-part as well as that of atoms due to increased fluctuations that result from reduced dimensions. In recent years, the interest in studying quantum dot nuclear spin systems and their coupling to confined electron spins has been fueled by its direct implication for possible applications of such systems in quantum information processing as well as by the fascinating nonlinear (quantum-)dynamics of the coupled electron-nuclear spin system. In this article, we review experimental work performed over the last decades in studying this mesoscopic,coupled electron-nuclear spin system and discuss how optical addressing of electron spins can be exploited to manipulate and read-out quantum dot nuclei. We discuss how such techniques have been applied in quantum dots to efficiently establish a non-zero mean nuclear spin polarization and, most recently, were used to reduce fluctuations of the average quantum dot nuclear spin orientation. Both results in turn have important implications for the preservation of electron spin coherence in quantum dots, which we discuss. We conclude by speculating how this recently gained understanding of the quantum dot nuclear spin system could in the future enable experimental observation of quantum-mechanical signatures or possible collective behavior of mesoscopic nuclear spin ensembles.

description: The son is configured into the orbit of Cuban popular music as the mulatto music genre par excellence,  thanks to the amalgam of musical elements and structural features of Spanish and African origins.
In its heyday - when are defined new modes of interpretation and new sonic possibilities - shares political and cultural unrest of vanguards that, through the recognition of the African component, try to build a coherent concept of nation, highlighting the contribution of black people to cultural and political processes. This work is based on the hypotheses suggested in some cuban studies recently published, about the causal relationship between the son’s development and the shape of national identity in the period of the Wars of Independence, to come to find through the  thematic analysis of representative texts the genre's functioning within this perspective.

The role of Mie scattering in the seeding of matter-wave superradiance

description: Matter-wave superradiance is based on the interplay between ultracold atoms coherently organized in momentum space and a backscattered wave. Here, we show that this mechanism may be triggered by Mie scattering from the atomic cloud. We show how the laser light populates the modes of the cloud, and thus imprints a phase gradient on the excited atomic dipoles. The interference with the atoms in the ground state results in a grating, that in turn generates coherent emission, contributing to the backward light wave onset. The atomic recoil 'halos' created by the scattered light exhibit a strong anisotropy, in contrast to single-atom scattering.
Fractional topological insulators of Cooper pairs induced by proximity effect

description: Certain insulating materials with strong spin-orbit coupling can conduct currents along their edges or surfaces. This phenomenon arises from the non-trivial topological properties of the electronic band-structure, and is somewhat similar to the integer quantum Hall effect of electrons in strong magnetic fields. Topological insulators analogous to the fractional quantum Hall effect are also possible, but have not yet been observed in any material. Here we show that a quantum well made from a topological band insulator such as Bi2Se3 or Bi2Te3, placed in contact with a superconductor, can be used to realize a two-dimensional topological state with macroscopic many-body quantum entanglement whose excitations carry fractional amounts of electron's charge and spin. This fractional topological insulator is a "pseudogap" state of induced spinful p-wave Cooper pairs, fundamentally significant to quantum field theory and applicable to spintronic devices and quantum computing.

First-principles characterization of ferromagnetism in N-doped SrTiO3 and BaTiO3

subject: FOS: Physical sciences

description: The spin-polarization and magnetic coupling character of N-doped SrTiO3 and BaTiO3 are studied through first-principles calculations. The substitutional N doping at O sites leads to a half-metallic property and produces a magnetic moment of 1.0 μB. The magnetic interaction between the nearest and next-nearest N dopants results in a strong ferromagnetic coupling. When the distance between the N dopants is larger than 7 Å, the ground state of the system tends to be paramagnetic. A nitrogen-concentration threshold to produce the ferromagnetism is estimated. The calculated results give a good explanation for the experimentally observed ferromagnetism in N-doped SrTiO3 and BaTiO3.

description: Starting from a due reflection on Miguel Barnet’s Cimarrón as the first experiment on a testimony-novel – and considering the problems and contradictions of a cultural and political operation in which the witness-informant’s voice risks being overcome or at least misinterpreted by the author-transcriber – this paper goes on to consider the evolution of the testimony genre in 1990s Cuba, where women of African descent often intervened by speaking or writing, and managed to impose their views autonomously.
