description: Excitons in vertically stacked type-II quantum dots experience the topological magnetic phase and demonstrate the Aharonov-Bohm oscillations in the emission intensity. Photoluminescence of vertically stacked ZnTe/ZnSe quantum dots is measured in magnetic fields up to 31 T. The Aharonov-Bohm oscillations are found in the magnetic-field dependence of emission intensity. The positions of the peaks of the emission intensity are in a good agreement with numerical simulations of excitons in stacked quantum dots.

description: We introduce a new class of Wasserstein-type distances specifically designed to tackle questions concerning stability and convergence to equilibria for kinetic equations. Thanks to these new distances, we improve some classical estimates by Loeper and Dobrushin on Vlasov-type equations, and we present an application to quasineutral limits.

description: Undone is a body of artwork consisting of three, sculptural elements and a video component. All of the work conceptually addresses the use of text in culture, personally and politically. Sedition, constructed from cast letterpress type, borrows text from books banned in the United States, examining power relationships, regulation of information, constructed identity and the subjectivity of freedom. Quell I and Quell II consist of the spacers, between lines and words, in lead type. These material silences carve out a quiet place for the viewer, reinforcing the importance of reprieve. Immolation is edited from images of burning New York Times pages against the sky across a twelve-hour period. The silent film is rhythmic, alternating between flames and sky, asking questions about the reliability of the newspaper, the lifespan of the news and the effects of the information contained within. All of the work is meant to be open and contemplative, leaving room for the viewer to have a unique experience, shaped by his or her own history.

description: Ecological systems, as is often noted, are complex. Equally notable is the generalization that complex systems tend to be oscillatory, whether Huygens' simple patterns of pendulum entrainment or the twisted chaotic orbits of Lorenz’ convection rolls. The analytics of oscillators may thus provide insight into the structure of ecological systems. One of the most popular analytical tools for such study is the Kuramoto model of coupled oscillators. We apply this model as a stylized vision of the dynamics of a well-studied system of pests and their enemies, to ask whether its actual natural history is reflected in the dynamics of the qualitatively instantiated Kuramoto model. Emerging from the model is a series of synchrony groups generally corresponding to subnetworks of the natural system, with an overlying chimeric structure, depending on the strength of the inter-oscillator coupling. We conclude that the Kuramoto model presents a novel window through which interesting questions about the structure of ecological systems may emerge.

description: In the present paper, we investigate the collapsed phase of the interacting partially-directed self-avoiding walk (IPDSAW) that was introduced in Zwanzig and Lauritzen (1968). We provide sharp asymptotics of the partition function inside the collapsed phase, proving rigorously a conjecture formulated in Guttmann (2015) and Owczarek et al. (1993). As a by-product of our result, we obtain that, inside the collapsed phase, a typical IPDSAW trajectory is made of a unique macroscopic bead, consisting of a concatenation of long vertical stretches of alternating signs, outside which only finitely many monomers are lying.

Two Representations of the Voice and its Relationship to Subjectivity
Creators: name: Farrell, John Joseph
Publisher: name: Maryland Shared Open Access Repository
Year: 2010

description: The two works that comprise my thesis exhibit, Siren and In the Name of the Voice Shines the Light, depict mysterious dimensions of the relationship between language, subjectivity and the physical world.  To accomplish this, these video pieces leverage the power inherent in representations of disability and the voice, two phenomena that generate both fascination and anxiety in our culture because they resist reductive categorization and symbolic closure. Both pieces amplify these effects by mixing fictional and non-fictional elements into disjointed forms that undermine the possibility of a stable interpretive framework even as they draw attention to the processes of translation and interpretation themselves. My work uses gaps within and between the fields of sound and vision as metaphors for the imperfection inherent in all acts of communication and, by extension, for a notion of subjectivity that holds it to be a series of voids in the matrix of material substance. Since it seems thoroughly embedded among deterministic, material forces, subjectivity might only be open and free if this matrix is incomplete and inconsistent and not because of the activity any separate, non-material forces or substances. In what follows I will briefly sketch some of the work's foundations in my personal engagement with certain works of art.  I will then describe the properties, effects and rationale of each piece as I saw them during the process of their creation.

description: The high-field magnetic properties and magnetic order of the gem mineral green dioptase Cu$_6[$Si$_6$O$_{18}]\cdot 6$H$_2$O have been studied by means of single-crystal neutron diffraction in magnetic fields up to $21~$T and magnetization measurements up to $30~$T. In zero field, the Cu$^{2+}$-moments in the antiferromagnetic chains are oriented along the $c$-axis with a small off-axis tilt. For a field applied parallel to the $c$-axis, the magnetization shows a spin-flop-like transition at $B^*=12.2~$T at $1.5~$K. Neutron diffraction experiments show a smooth behavior in the intensities of the magnetic reflections without any change in the periodicity of the magnetic structure. Bulk and microscopic observations are well described by a model of ferromagnetically coupled antiferromagnetic $XXZ$ spin-$\frac{1}{2}$ chains, taking into account a change of the local easy-axis direction. We demonstrate that the magnetic structure evolves smoothly from a deformed Néel state at low fields to a deformed spin-flop state in a high field via a strong crossover around $B^*$. The results are generalized for different values of interchain coupling and spin anisotropy.

description: We investigate the pressure-temperature phase diagram of YbIr$_2$Si$_2$ by measuring the electrical resistivity $ρ(T)$. In contrast to the widely investigated YbRh$_2$Si$_2$, YbIr$_2$Si$_2$ is a paramagnetic metal below $p_c\simeq 8$ GPa. Interestingly, a first-order, presumably ferromagnetic, transition develops at $p_c$. Similar magnetic properties were also observed in YbRh$_2$Si$_2$ and YbCu$_2$Si$_2$ at sufficiently high pressures, suggesting a uniform picture for these Yb compounds. The ground state of YbIr$_2$Si$_2$ under pressure can be described by Landau Fermi-liquid (LFL) theory, in agreement with the nearly ferromagnetic Fermi-liquid (NFFL) model. Moreover, evidence of a weak valence transition, characterized by a jump of the Kadowaki-Woods (KW) ratio as well as an enhancement of the residual resistivity $ρ_0$ and of the quasiparticle-quasiparticle scattering cross section, is observed around 6 GPa.

description: The colour and luminosity distributions of red galaxies in the cluster Abell 1185 (z=0.0325) were studied down to M*+8 in the B, V and R bands. The colour-magnitude (hereafter CM) relation is linear without evidence for a significant bending down to absolute magnitudes which are seldom probed in literature (M_R=-12.5 mag). The CM relation is thin (+/-0.04 mag) and its thickness is quite independent from the magnitude. The luminosity function of red galaxies in Abell 1185 is adequately described by a Schechter function, with a characteristic magnitude and a faint end slope that also well describe the LF of red galaxies in other clusters. There is no passband dependency of the LF shape other than an obvious M* shift due to the colour of the considered population. Finally, we conclude that, based on colours and luminosity, red galaxies form an homogeneous population over four decades in stellar mass, providing a second evidence against faint red galaxies being a recent cluster population.

THE THIRD SPACE

description: The Third Space is a video installation that delivers the socio-political issue between the Tibetan and Chinese people living in the United States. The installation utilizes the form of dual projection to create an immersive environment. The installation negotiates the notion of identity both and across cultures by constructing and deconstructing the space in two opposite sides of the wall in a black box. The bridge symbolizes the permeable boundary that connects and separates the two sides and is also a metaphor for the invisible line which represents the border. The fading sound effect of the interviewees creates the dynamic polarity of the debate that allows an open interpretation of the subject, simulating the confusion and cacophony of any real world conflict. The Third Space is an attempt to investigate the politics of social identities from conflict to conversation, in a space that divide humans into two ethnic groups, in this case, Tibetans and Chinese; their arguments center on the ongoing issues of cultural conflict that have resulted in human atrocities.
Can altered body position alleviate post-exercise pulmonary diffusing capacity impairment?
Creators: name: Stewart, Ian Braidwood
Publisher: name: University of British Columbia
Year: 2009

description: Pulmonary diffusing capacity for carbon monoxide (Dlco), alveolar-capillary membrane diffusing capacity (Dm), and pulmonary capillary blood volume (Vc) are all significandy reduced following exercise. It is unknown if measurement position affects this impaired gas transfer postexercise. Prior to (baseline) and 15 minutes, 1, 2, and 4 hours following an incremental cycle to fatigue Dlco, Dm, and Vc were recorded in 10 healthy male subjects in both a supine and upright seated position. It was expected that the supine post-exercise measurement position would significantly reduce the decrement in Vc and thus Dlco, by facilitating a return of blood to the thoracic cavity. With removal of the 15 minute data, due to the lack of achievement of a resting cardiovascular state (heart rate, systolic and diastolic blood pressure all significantly different from baseline), a significant reduction in Dlco, Dm, and Vc was observed 1, 2, and 4 hours postexercise, as indicated in Table 1. [TABLE 1] There was a significant difference between positions for Dlco (4.66+0.98 vs. 5.22±0.89, seated vs. supine, p=0.022) and Dm (6.28±1.36 vs. 7.00+1.32, seated vs. supine, p=0.016), but there was no position effect for Vc. Nor was there any significant interaction between the positions over time for Dlco, Dm, or Vc. The change in Dlco appears to be primarily due to a decrease in Vc. The limited decrease in Dm in the supine position was likely due to a redistribution of blood within the lung, due to gravity, enhancing the surface area available for diffusion. Although the mechanism for the reduction in Vc cannot be determined from this data, a passive relocation of blood into the periphery due to gravity can be discounted, indicating that active vasoconstriction of the pulmonary vasculature and/or peripheral vasodilatation maybe occurring post-exercise. This is the first data to indicate that the maintained diffusion impairment is independent of measurement position.

description: We calculate the subgap current in planar superconducting tunnel junctions with thin-film diffusive leads. It is found that the subharmonic gap structure of the tunnel current scales with an effective tunneling transparency which may exceed the junction transparency by up to two orders of magnitude depending on the junction geometry and the ratio between the coherence length and the elastic scattering length. These results provide an alternative explanation of anomalously high values of the subgap current in tunnelling experiments often ascribed to imperfection of the insulating layer. We also discuss the effect of finite lifetime of quasiparticles as the possible origin of additional enhancement of multiparticle tunnel currents.

description: Spin excitations of magnetic thin films are the founding element for novel transport concepts in spintronics, magnonics, and magnetic devices in general. While spin dynamics have been extensively studied in bulk materials, their behaviour in mesoscopic films is less known due to experimental limitations. Here, we employ Resonant Inelastic X-Ray Scattering to investigate the spin excitation spectrum in mesoscopic Fe films, from bulk-like down to 3 unit cells thick. In bulk-like samples, we find isotropic, dispersive ferromagnons consistent with the dispersion observed by neutron scattering in bulk single crystals. As the thickness is reduced, these ferromagnons survive and evolve anisotropically: renormalising to lower energies along the out-of-plane direction while retaining their dispersion in the in-plane direction. This thickness dependence is captured by simple Heisenberg model calculations accounting for the confinement in the out-of-plane direction through the loss of Fe bonds. Our findings highlight the effects of mesoscopic scaling on spin dynamics and identify thickness as a knob for fine-tuning and controlling magnetic properties in films.

description: It is well known that a rotating superconductor produces a magnetic field proportional to its angular velocity. The authors conjectured earlier, that in addition to this so-called London moment, also a large gravitomagnetic field should appear to explain an apparent mass increase of Niobium Cooper-pairs. A similar field is predicted from Einstein's general relativity theory and the presently observed amount of dark energy in the universe. An experimental facility was designed and built to measure small acceleration fields as well as gravitomagnetic fields in the vicinity of a fast rotating and accelerating superconductor in order to detect this so-called gravitomagnetic London moment. This paper summarizes the efforts and results that have been obtained so far. Measurements with Niobium superconductors indeed show first signs which appear to be within a factor of 2 of our theoretical prediction. Possible error sources as well as the experimental difficulties are reviewed and discussed. If the gravitomagnetic London moment indeed exists, acceleration fields could be produced in a laboratory environment.

In order to perform the test, the following data set are considered: strong lensing systems and galaxy cluster measurements (gas mass fractions). No specific cosmological model is adopted, only a flat universe is assumed. { By considering two $η(z)$ parametrizations, It is observed that the CDDR remain redshift independent within $1.5σ$ which is in full agreement with other recent tests involving cosmological data}. It is worth to comment that our results are independent of the baryon budget of galaxy clusters.

description: Motivated by impurity-induced magnetic ordering phenomena in spin-gap materials like TlCuCl3, we develop a mean-field theory for strongly disordered antiferromagnets, designed to capture the broad distribution of coupling constants in the effective model for the impurity degrees of freedom. Based on our results, we argue that in the presence of random magnetic couplings the conventional first-order spin-flop transition of an anisotropic antiferromagnet is split into two transitions at low temperatures, associated with separate order parameters along and perpendicular to the field axis. We demonstrate the existence of either a bicritcal point or a critical endpoint in the temperature-field phase diagram, with the consequence that signatures of the spin flop are more pronounced at elevated temperature.

description: We have performed a deep optical imaging of 3C 58 SNR with the NOT in the B and V bands to detect the optical counterpart of the associated pulsar J0295+6449 and its torus-like wind nebula visible in X-rays. We analyzed our data together with the archival data obtained with the Chandra in X-rays and with the Spitzer in the mid-IR. We detect a faint extended elliptical object with B=24.06 and V=23.11 whose peak brightness and center position are consistent at the sub-arcsecond level with the position of the pulsar. Its morphology and orientation are in excellent agreement with the torus-like pulsar nebula, seen almost edge on in X-rays although its extension is only about a half of that in X-rays. In the optical we likely see only the brightest central part of the torus with the pulsar. The object is identical to the counterpart of the torus recently detected in the mid-IR. The estimated pulsar contribution to the optical flux is less than 10%. Combinig the optical/mid-IR fluxes and X-ray power-law spectrum extracted from the spatial region constrained by the optical/IR source extent we compile a tentative multi-wavelength spectrum of the central part of the nebula. Within uncertainties of the interstellar extinction it is reminiscent of either the Crab or B0540-69 pulsar wind nebula spectra. The properties of the object strongly suggest it to be the optical counterpart of the 3C 58 pulsar + its wind nebula system, making 3C 58 the third member of such a class of the torus-like systems identified in the optical and mid-IR.

description: We introduce, and numerically study, a system of $N$ symplectically and globally coupled standard maps localized in a $d=1$ lattice array. The global coupling is modulated through a factor $r^{-α}$, being $r$ the distance between maps. Thus, interactions are {\it long-range} (nonintegrable) when $0\leqα\leq1$, and {\it short-range} (integrable) when $α>1$. We verify that the largest Lyapunov exponent $λ_M$ scales as $λ_{M} \propto N^{-κ(α)}$, where $κ(α)$ is positive when interactions are long-range, yielding {\it weak chaos} in the thermodynamic limit $N\to\infty$ (hence $λ_M\to 0$). In the short-range case, $κ(α)$ appears to vanish, and the behaviour corresponds to {\it strong chaos}. We show that, for certain values of the control parameters of the system, long-lasting metastable states can be present. Their duration $t_c$ scales as $t_c \propto N^{β(α)}$, where $β(α)$ appears to be numerically consistent with the following behavior: $β>0$ for $0 \le α< 1$, and zero for $α\ge 1$. All these results exhibit major conjectures formulated within nonextensive statistical mechanics (NSM). Moreover, they exhibit strong similarity between the present discrete-time system, and the $α$-XY Hamiltonian ferromagnetic model, also studied in the frame of NSM.

description: We use holography to investigate the dynamics of a vortex-anti-vortex dipole in a strongly coupled superfluid in 2+1 dimensions. The system is evaluated in numerical real-time simulations in order to study the evolution of the vortices as they approach and eventually annihilate each other. A tracking algorithm with sub-plaquette resolution is introduced which permits a high-precision determination of the vortex trajectories. With the increased precision of the trajectories it becomes possible to directly compute the vortex velocities and accelerations. We find that in the holographic superfluid the vortices follow universal trajectories independent of their initial separation, indicating that a vortex-anti-vortex pair is fully characterized by its separation. Subtle non-universal effects in the vortex motion at early times of the evolution can be fully attributed to artifacts due to the numerical initialization of the vortices. We also study the dependence of the dynamics on the temperature of the superfluid.

description: The valley degree of freedom in many-valley semiconductors provides a new paradigm for storing and processing information in valleytronic and quantum-computing applications. Achieving practical devices require all-electric control of long-lived valley-polarized states, without the use of strong external magnetic fields. Attributable to the extreme strength of the carbon-carbon bond, diamond possesses exceptionally stable valley states which provides a useful platform for valleytronic devices. Using ultra-pure single-crystalline diamond, we here demonstrate electrostatic control of valley-currents in a dual gate field-effect transistor, where the electrons are generated with a short UV pulse. The charge -- and the valley -- current measured at receiving electrodes are controlled separately by varying the gate voltages. A proposed model based on drift-diffusion equations coupled through rate terms, with the rates computed by microscopic Monte Carlo simulations, is used to interpret experimental data. As an application, valley-current charge state modulation of nitrogen-vacancy (NV) centers is demonstrated.

description: We demonstrate that a new tool, a model independent numerical Eliashberg inversion of the optical self-energy, based on maximum entropy considerations can be used to extract the magnetic excitation spectra of high-transition-temperature superconductors. In Bi-2212 we explicitly show that the magnetic mode that dominates the self-energy at low temperatures directly evolves out of a smooth transfer of spectral weight to the mode from the continuum just above it. This redistribution starts already at 200 K in optimally doped materials but is much weaker in overdoped samples. This provides evidence for the magnetic origin of the superconductivity and presents a challenge to theories of the spin susceptibility and to neutron scattering experiments in high-temperature superconductors.

description: We study neutrino-nucleus charged-current reactions on finite nuclei for the situation in which an outgoing muon and a proton are detected in coincidence, i.e., we focus on semi-inclusive cross sections. We limit our attention to one-body current interactions (quasielastic scattering) and assess the impact of different nuclear effects in the determination of the neutrino energy. We identify the regions in phase space where the neutrino energy can be reconstructed relatively well, and study whether the cross section in those regions is significant. Our results indicate that it is possible to filter more than 50% of all events according to the muon and proton kinematics, so that for the DUNE and T2K fluxes the neutrino energy can be determined with an uncertainty of less than 1% and 3%, respectively. Furthermore, we find that the reconstructed neutrino energy does not depend strongly on how one treats the final-state interactions and is not much affected by the description of the initial state. On the other hand, the estimations of the uncertainty on the neutrino energy show important sensitivity to the modeling of the initial state.

description: In the Skyrme model, atomic nuclei are identified with solitonic configurations. If the pion mass is set to zero, these configurations are spherical shells of energy with a fullerene-like appearance and are well approximated by a simple rational map ansatz. Using simulated annealing, we have calculated minimum energy configurations for non-zero pion mass and have found that they are less round and are less well approximated by the rational map ansatz.

description: The dataset consists of spatially-explicit information on large- and small-scale fishing effort, harnessing vessel tracking data and participatory mapping. In particular, five fishing effort files are provided: three shapefiles informing on LSF (N.1 at 500th-degree resolution in GSA 10, and N.2 at 100th-degree resolution within the case study area) and two shapefiles on SSF (consisting of the digitised polygons and the related gridded data at 0.01°x 0.01° within the case study area, respectively). In all the shapefiles, the attribute table displays the cell ID and the geographical coordinates of the vertices of each cell. The common lattice grid used within the case study area (released too, as "feamp_grid") promotes the joining and overlaying of the released LSF and SSF effort data. A README.txt file is provided and contains the table schemas and additional information. Furthermore,  the chain of the operations concerning the SSF datasets was wrapped into a single process using the QGIS graphical modeler and released as .model3 file. It allows even novice GIS users to easily reproduce the workflow with their own set of inputs (i.e., digitised SSF polygons and aggregation grid), saving time and effort. A small guide is also shared (“step-by-step_guide.pdf”), to help users add the provided tools and run the final model "effort_grid.model3".
The effects of group process and sport imagery on the sport experience of high school athletes

description: As sport begins to gain momentum, partly due to the extreme value placed on professional athletics, the study and use of sport psychology has also gained strength. Much, if not all, of its focus has centered on optimizing individual athletic performance. Little, or no attention has been placed on fostering a sport unit whose basis is individual growth and learning. As we enter the new century, researchers and teachers alike must begin to align the education of sport toward the multitude of athletes, including adolescent ones, who will not find a home in professional athletics, but who must take the skills learned in the sporting environment into other avenues of life. The purpose of the study is two fold : (1) to investigate the role of group development toward the effectiveness of an imagery training program; and (2) to investigate the impact of imagery toward enhancing sport experience. Qualitative methodology, specifically semi-structured interview analysis, was utilized in this study. Eight (8) high school sport leaders participated in a eight week sport imagery training program. The program was driven by a group counselling approach (Amundson, Westwood, Borgen, and Pollard, 1989), which has received support in non-sport settings, but prior to this study had not been tested with athletes. The study found that the group process greatly impacted the learner and provided athletes a different perspective in which to view their sport experience. Content analysis uncovered four categories: Group Characteristics, Learning Factors, Application Factors, and Program Limitations, under which sixteen themes were identified. Definitions and interview support are offered in the results chapter, and further discussion is presented in the chapter five. The findings of the study are discussed to provide the impetus for future research into the budding field of sport counselling. In addition, suggestions for current coaches and teachers are presented.

description: Using ultraviolet (UV) light curves we constrain the circumstellar environments of 1080 Type Ia supernovae (SNe Ia) within $z<0.5$ from archival Galaxy Evolution Explorer (GALEX) observations. All SNe Ia are required to have pre- and post-explosion GALEX observations to ensure adequate subtraction of the host-galaxy flux. Using the late-time GALEX observations we look for the UV excess expected from any interaction between the SN ejecta and circumstellar material (CSM). Four SNe Ia are detected near maximum light and we compare the GALEX photometry to archival data, but we find none of our targets show convincing evidence of CSM interaction. A recent Hubble Space Telescope (HST) survey estimates that $\sim6\%$ of SNe Ia may interact with distant CSM, but statistical inferences are complicated by the small sample size and selection effects. By injecting model light curves into our data and then recovering them, we constrain a broad range of CSM interactions based on the CSM interaction start time and the maximum luminosity. Combining our GALEX non-detections with the HST results, we constrain occurrence of late-onset CSM interaction among SNe Ia with moderate CSM interaction, similar to that observed in PTF11kx, to $f_\text{CSM}\lesssim5.1\%$ between $0-500$ days after discovery and $\lesssim2.7\%$ between $500-1000$ days after discovery at $90\%$ confidence. For weaker CSM interactions similar to SN 2015cp, we obtain limits of $\lesssim16\%$ and $\lesssim4.8\%$, respectively, for the same time ranges.
