description: We study a model of two interacting levels that are attached to two electronic leads, where one of the levels is attached very weakly to the leads. We use rate equations method to calculate the average current and the noise of electrons transmitted through the two levels. We show that the shot noise is enhanced due to the interactions and that the Fano factor depends on the properties of the couplings between the levels and the leads. We study both sequential tunneling and cotunneling processes and show that there is a range of parameters in which the cotunneling processes affect the noise significantly, even though most of the current is carried by sequential tunneling processes.

«La vita è sogno» o «La vita è un sogno»? Storia e ragioni della traduzione di un titolo classico
Creators: name: Antonucci, Fausta
Publisher: name: Università degli Studi di Milano
Year: 2012

description: Nell’articolo si esamina la storia della traduzione in italiano del titolo del capolavoro di Pedro Calderón de la Barca, «La vida es sueño». Dopo tre secoli in cui, alla stregua di altre lingue (inglese, francese, tedesco), il titolo veniva reso con «La vita è un sogno», si è passati a una fase novecentesca in cui è prevalsa l’intitolazione «La vita è sogno», sempre più uniformemente adottata a partire dalla traduzione ad opera di Gherardo Marone (pubblicata nel 1920). L’autrice, che ha adottato per la sua recente traduzione (2009) il titolo «La vita è un sogno», riflette sulle modalità di resa in italiano di sintagmi analoghi (parti nominali di un predicato) e analizza le scelte traduttive che, nel corpo del testo, hanno adottato per lo stesso sintagma Orioli, Cancelliere e Puccini, autori di tre importanti traduzioni dell’opera calderoniana pubblicate rispettivamente nel 1967, 1985 e 1990.

This essay examines italian translation’s story of the title ‘La vida es sueño’, Calderón de la Barca’s masterpiece. After three centuries in which, as other languages (english, french, german) currently do, the title was translated as ‘La vita è un sogno’, in the XXth century predominates the title ‘La vita è sogno’, starting from Gherardo Marone’s translation (1920). Fausta Antonucci, who adopted for her recent translation (2009) the title 'La vita è un sogno', examines how similar noun phrases are expressed in italian, and analyzes how the same noun phrase (“la vida es sueño”) is translated, inside the text, by Orioli, Cancelliere and Puccini, authors of three important translations from the calderonian masterpiece, published in 1967, 1985 and 1990.

Manifestations of Dynamical Facilitation in Glassy Materials

description: By characterizing the dynamics of idealized lattice models with a tunable kinetic constraint, we explore the different ways in which dynamical facilitation manifests itself within the local dynamics of glassy materials. Dynamical facilitation is characterized both by a mobility transfer function, the propensity for highly-mobile regions to arise near regions that were previously mobile, and by a facilitation volume, the effect of an initial dynamical event on subsequent dynamics within a region surrounding it. Sustained bursts of dynamical activity -- avalanches -- are shown to occur in kinetically constrained models, but, contrary to recent claims, we find that the decreasing spatiotemporal extent of avalanches with increased supercooling previously observed in granular experiments does not imply diminishing facilitation. Viewed within the context of existing simulation and experimental evidence, our findings show that dynamical facilitation plays a significant role in the dynamics of systems investigated over the range of state points accessible to molecular simulations and granular experiments.

General relations for quantum gases in two and three dimensions. Two-component fermions
Creators: name: Werner, Félix

Year: 2012
Subjects: subject: Quantum Gases (cond-mat.quant-gas)
subject: FOS: Physical sciences

description: We derive exact relations for $N$ spin-1/2 fermions with zero-range or short-range interactions, in continuous space or on a lattice, in $2D$ or in $3D$, in any external potential. Some of them generalize known relations between energy, momentum distribution $n(k)$, pair distribution function $g^{(2)}(r)$, derivative of the energy with respect to the scattering length $a$. Expressions are found for the second order derivative of the energy with respect to $1/a$ (or to $\ln a$ in $2D$). Also, it is found that the leading energy corrections due to a finite interaction range, are proportional to the effective range $r\_e$ in $3D$ (and to $r\_e^2$ in $2D$) with exprimable model-independent coefficients, that give access to the subleading short distance behavior of $g^{(2)}(r)$ and to the subleading $1/k^6$ tail of $n(k)$. This applies to lattice models for some magic dispersion relations, an example of which is given. Corrections to exactly solvable two-body and three-body problems are obtained. For the trapped unitary gas, the variation of the finite-$1/a$ and finite $r\_e$ energy corrections within each $SO(2,1)$ energy ladder is obtained; it gives the frequency shift and the collapse time of the breathing mode. For the bulk unitary gas, we compare to fixed-node Monte Carlo data, and we estimate the experimental uncertainty on the Bertsch parameter due to a finite $r\_e$.

description: The spectrum of resonance fluorescence is calculated for a two-level system excited by an intense, ultrashort x-ray pulse made available for instance by free-electron lasers such as the Linac Coherent Light Source. We allow for inner-shell hole decay widths and destruction of the system by further photoionization. This two-level description is employed to model neon cations strongly driven by x rays tuned to the 1s 2p-1 --> 1s-1 2p transition at 848 eV; the x rays induce Rabi oscillations which are so fast that they compete with Ne 1s-hole decay. We predict resonance fluorescence spectra for two different scenarios: first, chaotic pulses based on the self-amplified spontaneous emission principle, like those presently generated at x-ray free-electron-laser facilities and, second, Gaussian pulses which will become available in the foreseeable future with self-seeding techniques. As an example of the exciting opportunities derived from the use of seeding methods, we predict, in spite of above obstacles, the possibility to distinguish at x-ray frequencies a clear signature of Rabi flopping in the spectrum of resonance fluorescence.

Metaphor and boundary

Year: 2011

description: The use of metaphors play in Kantian thought a fundamental role. In my paper I argue that Reimarus’ Logic could be considered as a source for Kant's use of some metaphors. In his Logic, in fact, Reimarus anticipates the geographical metaphor by which it is possible to distinguish between limits and boundary, to draw the map of reason and to put her in front of a court. The aim of my analysis is to show that Reimarus’ Logic could be considered as a turning point in Wolffian philosophy on the topic of the definition of experience in relation to unity of the system.

description: We consider the Mahler measure of the polynomial 1+x_1+x_2+x_3+x_4, which is the first case not yet evaluated explicitly. A conjecture due to F. Rodriguez-Villegas represents this Mahler measure as a special value at the point 4 of the L-function of a modular modular form of weight 3. We prove that this Mahler measure is equal to a linear combination of double L-values of certain meromorphic modular forms of weight 4.

Aging gracefully : a case study of seniors in Kelowna's housing market
Creators: name: Brown, Heather Catherine
Publisher: name: University of British Columbia
Year: 2013

description: This thesis explores the most salient housing issues experienced by seniors as homeowners and renters living in the city of Kelowna, British Columbia, known as one of the most expensive housing markets in Canada. Barriers and challenges in obtaining and maintaining their housing, housing affordability, and aging-in-place are the primary issues discussed. Avenues for further research are also addressed. Data for this study were collected between June and October 2011, based on a survey of 45 senior homeowners and 34 senior renters as well as semi-structured interviews conducted with 12 key informants. The sample was drawn from the population of seniors (aged 65 or older) who have a primary residence in the city of Kelowna. All participants were required to be Canadian citizens and living independently at the time the research was conducted. Results from the case study point out those seniors in Kelowna’s housing market, both homeowners and renters, face challenges and barriers with affordability, accessibility, adaptability and aging-in-place. Empirical data indicate that both senior homeowners and senior renters in Kelowna have major concerns in their search for adequate, accessible and affordable housing. This exploratory case study adds to the existing literature by highlighting the importance of understanding seniors’ housing experiences in the city of Kelowna. Significant issues such as accessibility, adaptability and aging-in-place are thoroughly discussed in this study Recommendations from this study include a need for more government support in the form of affordable housing, as well as possible policy initiatives addressing future housing construction in the city of Kelowna.

description: We have measured the thermopower across the metamagnetic transition of the heavy fermion compound CeRu2Si2 at temperatures down to 0.1K and magnetic fields up to 11.5T. We find a large negative enhancement of the thermopower on crossing the metamagnetic field, as well as a sudden change in slope. We argue that this is consistent with the Zeeman-driven deformation of the Fermi surface through a topological transition. The field dependence of the thermopower highlights the discrepancy between thermodynamic and transport properties across the metamagnetic transition.

Ein weiterer Kernpunkt ist die Implementierung digitaler Potentiometer über denen ein automatisierter Messvorgang mittels der „Shuldo-Test-Messsteuerungs-Software“ durchgeführt werden kann. Hierdurch wird dem Benutzer eine anwendungsfreundliche Umgebung zur Verfügung gestellt, um die Steigung und den Offset der Eingangsspannung über das Testtool in einem bestimmten Bereich automatisiert zu variieren.
description: The master thesis includes the introduction to the CERN projects and to the Shunt LDO controller. The regulator will be developed from revision 0.1 to revision 0.3. This will involve PCB development using Altium Designer, graphical user interface programming using Qt, as well as assembly and soldering work. The main point of the thesis is the validation of the SLDO voltage regulator for the pixel detectors of the ATLAS and CMS experiments at the HL-LHC. Another key point is the implementation of digital potentiometers over which an automated measurement process can be performed by means of the "Shuldo Test Measurement Control Software". This provides the user with an application-friendly environment to automatically adjust the slope and offset of the input voltage within a certain range via the test tool.

description: The low-energy dynamics of five-dimensional Yang-Mills theories compactified on S^1 can be described by a four-dimensional gauge theory coupled to a scalar field in the adjoint representation of the gauge group. Perturbative calculations suggest that the mass of this elementary scalar field is protected against power divergences, and is controlled by the size of the extra dimension R. As a first step in the study of this phenomenon beyond perturbation theory, we investigate the phase diagram of a SU(2) Yang-Mills theory in five dimensions regularized on anisotropic lattices and we determine the ratios of the relevant physical scales. The lattice system shows a dimensionally reduced phase where the four-dimensional correlation length is much larger than the size of the extra dimension, but still smaller than the four-dimensional volume. In this region of the bare parameter space, at energies below 1/R, the non-perturbative spectrum contains a \emph{light} scalar state. This state has a mass that is independent of the cut-off, and a small overlap with glueball operators. Our results suggest that light scalar fields can be introduced in a lattice theory using compactified extra dimensions, rather than fine tuning the bare mass parameter.

Turbulent magnetic field amplification driven by cosmic-ray pressure gradients

description: Observations of non-thermal emission from several supernova remnants suggest that magnetic fields close to the blastwave are much stronger than would be naively expected from simple shock compression of the field permeating the interstellar medium (ISM). We present a simple model which is capable of achieving sufficient magnetic field amplification to explain the observations. We propose that the cosmic-ray pressure gradient acting on the inhomogeneous ISM upstream of the supernova blastwave induces strong turbulence upstream of the supernova blastwave. The turbulence is generated through the differential acceleration of the upstream ISM which occurs as a result of density inhomogeneities in the ISM. This turbulence then amplifies the pre-existing magnetic field. Numerical simulations are presented which demonstrate that amplification factors of 20 or more are easily achievable by this mechanism when reasonable parameters for the ISM and supernova blastwave are assumed. The length scale over which this amplification occurs is that of the diffusion length of the highest energy non-thermal particles.

Relativistic collapse and explosion of rotating supermassive stars with thermonuclear effects

description: We present results of general relativistic simulations of collapsing supermassive stars with and without rotation using the two-dimensional general relativistic numerical code Nada, which solves the Einstein equations written in the BSSN formalism and the general relativistic hydrodynamics equations with high resolution shock capturing schemes. These numerical simulations use an equation of state which includes effects of gas pressure, and in a tabulated form those associated with radiation and the electron-positron pairs. We also take into account the effect of thermonuclear energy released by hydrogen and helium burning. We find that objects with a mass of 5x10^{5} solar mass and an initial metallicity greater than Z_{CNO}~0.007 do explode if non-rotating, while the threshold metallicity for an explosion is reduced to Z_{CNO}~0.001 for objects uniformly rotating. The critical initial metallicity for a thermonuclear explosion increases for stars with mass ~10^{6} solar mass. For those stars that do not explode we follow the evolution beyond the phase of black hole formation. We compute the neutrino energy loss rates due to several processes that may be relevant during the gravitational collapse of these objects. The peak luminosities of neutrinos and antineutrinos of all flavors for models collapsing to a BH are ~10^{55} erg/s. The total radiated energy in neutrinos varies between ~10^{56} ergs for models collapsing to a BH, and ~10^{45}-10^{46} ergs for models exploding.

description: We compute the strangeness and light-quark contributions Delta s, Delta u and Delta d to the proton spin in nf=2 lattice QCD at a pion mass of about 285 MeV and at a lattice spacing a approx 0.073 fm, using the non-perturbatively improved Sheikholeslami-Wohlert Wilson action. We carry out the renormalization of these matrix elements which involves mixing between contributions from different quark flavours. Our main result is the small negative value MSbar scheme value Delta s = -0.020(10)(4), at a scale mu = 7.4 GeV, of the strangeness contribution to the nucleon spin. The second error is an estimate of the uncertainty, due to the missing extrapolation to the physical point.

description: Short gamma-ray bursts (SGRBs) observed by {\it Swift} are potentially revealing the first insight into cataclysmic compact object mergers. To ultimately acquire a fundamental understanding of these events requires pan-spectral observations and knowledge of their spatial distribution to differentiate between proposed progenitor populations. Up to April 2012 there are only some 30% of SGRBs with reasonably firm redshifts, and this sample is highly biased by the limited sensitivity of {\it Swift} to detect SGRBs. We account for the dominant biases to calculate a realistic SGRB rate density out to $z\approx0.5$ using the {\it Swift} sample of peak fluxes, redshifts, and those SGRBs with a beaming angle constraint from X-ray/optical observations. We find an SGRB lower rate density of $8^{+5}_{-3}$ $\mathrm{Gpc}^{-3}\mathrm{yr}^{-1}$ (assuming isotropic emission), and a beaming corrected upper limit of $1100^{+700}_{-470} $ $\mathrm{Gpc}^{-3}\mathrm{yr}^{-1}$. Assuming a significant fraction of binary neutron star mergers produce SGRBs, we calculate lower and upper detection rate limits of $(1-180)$ yr$^{-1}$ by an aLIGO and Virgo coincidence search. Our detection rate is similar to the lower and realistic rates inferred from extrapolations using Galactic pulsar observations and population synthesis.

Youth's acceptance of mobile phone text messaging for STI health promotion
Creators: name: Symonds, Lindsay
Publisher: name: University of British Columbia
Year: 2013

description: Objectives: The objective of this study was to assess youths’ readiness to receive sexually transmitted infection (STI) sexual health promotion Short Message Services (SMS) (or text messages) from a public health nurse. Methods: An anonymous survey was given to youth aged 16 to 25 in a metropolitan Canadian city in 2 different areas: (1) youth attending two drop-in public health run sexual health youth clinics; and (2) youth at a campus of a large urban university. Results: One hundred and sixty six (n= 166) youth responded to the survey, of which 98% owned a mobile phone and 73% preferred sending and receiving SMS on their phones compared to other modes of communication. The youth in this study still expressed a desire for face-to-face interaction with a nurse for notifications of STI results (56%) or for asking sexual health questions (55%). There was preference for SMS from a nurse for reminders to wear condoms (31%) or reminders to call the nurse/clinic (40%). The youth overall agreed that SMS would provide a continued link between the nurse and themselves (60%) and the ability to use SMS would make it more likely for them to contact the nurse for a question or concern (78%). Conclusion: Youth are using SMS on their mobile phones at very high rates. There is general acceptance for SMS sent from a public health nurse in the form of reminders for condom use and for contacting a nurse/clinic, however the youth also indicated preference for face-to-face communication for more personal communications such as notification of STI results.

description: We analyze theoretically the resonant inelastic x-ray scattering (RIXS) at the Ni K edge in the stripe-ordered state of La_{2-x}Sr_xNiO_4 at x=1/3. In the calculation of RIXS spectra, the stripe-ordered ground state is described within the Hartree-Fock approximation by using a realistic tight-binding model for Ni3dγand O2p_{x, y} orbitals, and the electron correlations in the electronic excitation processes are taken into account within the random-phase approximation. The calculated RIXS spectrum shows a tail toward the low-energy region when the momentum transfer of photons equals the stripe vector Q, being consistent with a recent experimental result. The origin of this anomalous momentum dependence of RIXS spectra is discussed microscopically.

description: In this paper, I present a novel interpretation of the notion 'formative power' in Kant's "Critique of the Power of Judgment" (§65). I defend the view that for Kant the formative power is a fundamental, immaterial, intrinsic natural power in the organized being. It is a final cause that generates the purposive form of the materials of an organized being. Reading God's creation as the primary and nature's formative power as a secondary final cause of the purposive form of nature allows us to see the consistency of Kant’s theological and philosophical views in the field of biology.

Moreover if d is not greater than 6 then its belt diameter is bounded from above by 2. Also we show that these bounds are sharp. As a consequence we show that diameter of the edge graph of dual polytope for such zonotopes is not greater then 4 and 3 respectively.

description: In this paper, we revisit the forward, backward and bidirectional Bahl-Cocke-Jelinek-Raviv (BCJR) soft-input soft-output (SISO) maximum a posteriori probability (MAP) decoding process of rate-1 binary convolutional codes. From this we establish some interesting explicit relationships between encoding and decoding of rate-1 convolutional codes. We observe that the forward and backward BCJR SISO MAP decoders can be simply represented by their dual SISO channel encoders using shift registers in the complex number field. Similarly, the bidirectional MAP decoding can be implemented by linearly combining the shift register contents of the dual SISO encoders of the respective forward and backward decoders. The dual encoder structures for various recursive and non-recursive rate-1 convolutional codes are derived.

description: In contrast to perturbative QCD, the analytic QCD models have running coupling whose analytic properties correctly mirror those of spacelike observables. The discontinuity (spectral) function of such running coupling is expected to agree with the perturbative case at large timelike momenta; however, at low timelike momenta it is not known. In the latter regime, we parametrize the unknown behavior of the spectral function as a sum of (two) delta functions; while the onset of the perturbative behavior of the spectral function is set to be 1.0-1.5 GeV. This is in close analogy with the "minimal hadronic ansatz" used in the literature for modeling spectral functions of correlators. For the running coupling itself, we impose the condition that it basically merges with the perturbative coupling at high spacelike momenta. In addition, we require that the well-measured nonstrange semihadronic (V+A) tau decay ratio value be reproduced by the model. We thus obtain a QCD framework which is basically indistinguishable from perturbative QCD at high momenta (Q > 1 GeV), and at low momenta it respects the basic analyticity properties of spacelike observables as dictated by the general principles of the local quantum field theories.

A temporal analysis of Canadian dietary choices using the Canadian Community Health Survey Cycle 2.2 : does nutrient intake and diet quality vary on weekends versus weekdays?
Creators: name: Yang, Hui Wen
Publisher: name: University of British Columbia
Year: 2013

description: Since dietary intake varies from day to day, research on the timing of dietary behaviours is essential for understanding the complexity of contemporary dietary patterns needed to inform nutrition-related health policies and recommendations. Limited studies with inconsistent results have suggested that dietary intake differs on weekends versus weekdays. Although findings from outside of Canada have previously reported that energy intake is higher on weekend days, the nature of weekday-weekend variation in dietary intake among Canadians remains unknown. In response, this study evaluated the difference in energy, nutrient intake and diet quality on weekdays versus weekend days in the Canadian population and whether temporal differences were moderated by sex, age or employment status. Data were analyzed from participants aged >1 year, excluding pregnant or breastfeeding women (n=34,402) in the Canadian Community Health Survey Cycle 2.2, a nationally representative survey which included 24-hour dietary recall data. Linear regression models examined the difference in energy intake, nutrient intake and diet quality (assessed using Healthy Eating Index [HEI]) between weekdays (Monday-Thursday) and weekend days (Friday-Sunday). Caloric intake was found to be 62 kcal (SE = 23) higher on weekend days than on weekdays. Compared to weekdays, energy-adjusted weekend intakes of carbohydrates, protein, and the majority of micronutrients were significantly lower, ranging from 2.0% to 6.6% lower, while alcohol and cholesterol intakes were 66% and 10% higher on weekends, respectively. HEI was significantly lower on weekends than on weekdays (56.4 vs. 58.3 out of 100). With the exception of alcohol, the magnitude of weekday-weekend differences of most of the dietary outcomes did not differ substantially by sex, age or employment status. In conclusion, Canadians consume foods with a slightly less favorable nutrient profile and marginally poorer diet quality on weekends than on weekdays.
Six-dimensional Supergravity and Projective Superfields

description: We propose a superspace formulation of N=(1,0) conformal supergravity in six dimensions. The corresponding superspace constraints are invariant under super-Weyl transformations generated by a real scalar parameter. The known variant Weyl super-multiplet is recovered by coupling the geometry to a super-3-form tensor multiplet. Isotwistor variables are introduced and used to define projective superfields. We formulate a locally supersymmetric and super-Weyl invariant action principle in projective superspace. Some families of dynamical supergravity-matter systems are presented.

description: Cell membranes are anchored to the cytoskeleton via immobile inclusions. We investigate the effect of such anchors on the in-plane dynamics of a fluid membrane and mobile inclusions (proteins) embedded in it. The immobile particles lead to a decreased diffusion coefficient of mobile ones and suppress the correlated diffusion of particle pairs. Due to the long-range, quasi-two-dimensional nature of membrane flows, these effects become significant at a low area fraction (below one percent) of immobile inclusions.

description: We explore two fundamental questions at the intersection of sampling theory and information theory: how channel capacity is affected by sampling below the channel's Nyquist rate, and what sub-Nyquist sampling strategy should be employed to maximize capacity. In particular, we derive the capacity of sampled analog channels for three prevalent sampling strategies: sampling with filtering, sampling with filter banks, and sampling with modulation and filter banks. These sampling mechanisms subsume most nonuniform sampling techniques applied in practice. Our analyses illuminate interesting connections between under-sampled channels and multiple-input multiple-output channels. The optimal sampling structures are shown to extract out the frequencies with the highest SNR from each aliased frequency set, while suppressing aliasing and out-of-band noise. We also highlight connections between undersampled channel capacity and minimum mean-squared error (MSE) estimation from sampled data. In particular, we show that the filters maximizing capacity and the ones minimizing MSE are equivalent under both filtering and filter-bank sampling strategies. These results demonstrate the effect upon channel capacity of sub-Nyquist sampling techniques, and characterize the tradeoff between information rate and sampling rate.

description: We propose two possible experimental realizations of a 2+1 dimensional spacetime supersymmetry at a quantum critical point on the surface of three dimensional topological insulators. The quantum critical point between the semi-metallic state with one Dirac fermion and the s-wave superconducting state on the surface is described by a supersymmetric conformal field theory within $ε$-expansion. We predict the exact voltage dependence of the differential conductance at the supersymmetric critical point.

description: Stochastic differential equations (SDE) are widely used in modeling stochastic dynamics in literature. However, SDE alone is not enough to determine a unique process. A specified interpretation for stochastic integration is needed. Different interpretations specify different dynamics. Recently, a new interpretation of SDE is put forward by one of us. This interpretation has a built-in Boltzmann-Gibbs distribution and shows the existence of potential function for general processes, which reveals both local and global dynamics. Despite its powerful property, its relation with classical ones in arbitrary dimension remains obscure. In this paper, we will clarify such connection and derive the concise relation between the new interpretation and Ito process. We point out that the derived relation is experimentally testable.
