description: In this report we review recent experimental results on photoexcited carrier relaxation dynamics on high temperature superconductors (HTSC) probed by a femtosecond time-resolved optical spectroscopy, and compare the results with the data obtained on quasi two dimensional charge density waves. In these experiments, a femtosecond laser pump pulse excites electron-hole pairs via an inter-band transition in the material. These hot carriers rapidly release their energy via electron-electron and electron-phonon collisions reaching states near the Fermi energy within ~100 fs. If an energy gap is present in the low-energy density of states (DOS), it inhibits the final relaxation step and photoexcited carriers accumulate above the gap causing a transient change in reflectivity arising from excited state absorption. The relaxation and recombination processes of photoexcited quasiparticles, governed by the magnitude, anisotropy and the T-dependence of the low energy gap, are monitored by measuring the resulting photoinduced absorption as a function of time after the photoexcitation. This way, the studies of carrier relaxation dynamics give us direct information of the T-dependent changes in the low energy DOS. The technique is particularly useful to probe the systems with spatial inhomogeneities, where different local environments give rise to different relaxation rates. The data on series of HTSC-s show evidence for the coexistence of two distinct relaxation processes, whose T-dependences seem to be governed by two different energy scales: a T-independent pseudogap and a mean-field-like T-dependent gap that opens at Tc. The data suggest the origin of the two-gap behavior is in the intrinsic microscopic spatial inhomogeneity of these materials.

description: Constant curvature black holes are constructed by identifying points in anti-de Sitter space. In n dimensions, the resulting topology is R^{n-1} * S_1, as opposed to the usual R^2 * S_{n-2} Schwarzschild black hole, and the corresponding causal structure is displayed by a (n-1)-dimensional picture, as opposed to the usual 2-dimensional Kruskal diagram. The five dimensional case, which can be embedded in a Chern-Simons supergravity theory, is analyzed in detail.

description: Tailings management is one of several challenges faced by mines operating in dry environments. If tailings are exposed, with no vegetative cover, dust from mine sites can spread over long distances through eolian dispersion and water erosion, posing a risk to human and environmental health. Phytostabilization is a remediation technique which involves promoting vegetation growth on mine sites in order to prevent erosion and stabilize metals belowground. Here we report the results of a greenhouse study in which two native bunchgrasses (bluebunch wheatgrass and rough fescue) were evaluated for their ability to grow on alkaline mine tailings from the historic Afton mine when amended with a range of concentrations of locally available soil amendments (compost and wood ash). The addition of compost lowered tailings pH and increased organic matter content. A positive correlation between compost concentration and total biomass was observed, likely due to improved soil conditions. Shoot and root biomass of bluebunch wheatgrass was significantly greater than that of rough fescue on all treatments. Both candidates minimized shoot accumulation of metals with the exception of Mo which exceeded the domestic animal toxicity limit. The results revealed that compost is a promising amendment for promoting bunchgrass growth on these tailings.

description: An overarching computational framework unifying several optical theories to describe the temporal evolution of gold nanoparticles (GNPs) during a seeded growth process is presented. To achieve this, we used the inexpensive and widely available optical extinction spectroscopy, to obtain quantitative kinetic data. In situ spectra collected over a wide set of experimental conditions were regressed using the physical model, calculating light extinction by ensembles of GNPs during the growth process. This model provides temporal information on the size, shape, and concentration of the particles and any electromagnetic interactions between them. Consequently, we were able to describe the mechanism of GNP growth and divide the process into distinct genesis periods. We provide explanations for several longstanding mysteries, for example, the phenomena responsible for the purple-greyish hue during the early stages of GNP growth, the complex interactions between nucleation, growth, and aggregation events, and a clear distinction between agglomeration and electromagnetic interactions. The presented theoretical formalism has been developed in a generic fashion so that it can readily be adapted to other nanoparticulate formation scenarios such as the genesis of various metal nanoparticles.

description: This article investigates reconstructing the internal mass density of a numerical asteroid model using the gradient of a simulated gravity field as synthetic measurement data. Our goal is to advance the mathematical inversion methodology and find feasibility constraints for the resolution, noise and orbit selection for future space missions. We base our model on the shape of the asteroid Itokawa as well as on the recent observations and simulation studies which suggest that the internal density varies, increasing towards the center, and that the asteroid may have a detailed structure. We introduce randomized multiresolution scan algorithm which might provide a robust way to cancel out bias and artifact effects related to the measurement noise and numerical discretization. In this scheme, the inverse algorithm can reconstruct details of various sizes without fixing the exact resolution {\em a priori}, and the randomization minimizes the effect of discretization on the solution. We show that the adopted methodology provides an advantageous way to diminish the surface bias of the inverse solution. The results also suggest that a noise level below 80 Eotvos will be sufficient for the detection of internal voids and high density anomalies, if a sparse set of measurements can be obtained from a close-enough distance to the target.

In the vortex solid phase the current densities and the squared bare plasma frequencies decrease linearly with the magnetic field.

Causality in Time-Neutral Cosmologies

subject: FOS: Physical sciences

description: Gell-Mann and Hartle (GMH) have recently considered time-neutral cosmological models in which the initial and final conditions are independently specified, and several authors have investigated experimental tests of such models. We point out here that GMH time-neutral models can allow superluminal signalling, in the sense that it can be possible for observers in those cosmologies, by detecting and exploiting regularities in the final state, to construct devices which send and receive signals between space-like separated points. In suitable cosmologies, any single superluminal message can be transmitted with probability arbitrarily close to one by the use of redundant signals. However, the outcome probabilities of quantum measurements generally depend on precisely which past {\it and future} measurements take place. As the transmission of any signal relies on quantum measurements, its transmission probability is similarly context-dependent. As a result, the standard superluminal signalling paradoxes do not apply. Despite their unusual features, the models are internally consistent. These results illustrate an interesting conceptual point. The standard view of Minkowski causality is not an absolutely indispensable part of the mathematical formalism of relativistic quantum theory. It is contingent on the empirical observation that naturally occurring ensembles can be naturally pre-selected but not post-selected.

description: Detailed theoretical studies of the electronic structure of (InGa)(AsSb)/GaAs/GaP quantum dots are presented. This system is unique since it exhibits concurrently direct and indirect transitions both in real and momentum space and is attractive for applications in quantum information technology, showing advantages as compared to the widely studied (In,Ga)As/GaAs dots. We proceed from the inspection of the confinement potentials for ${\bf k}\neq 0$ and ${\bf k}= 0$ conduction and ${\bf k}= 0$ valence bands, through the formulation of ${\bf k}\cdot{\bf p}$ calculations for ${\bf k}$-indirect transitions, up to the excitonic structure of $Γ$-transitions. Throughout this process we compare the results obtained for dots on both GaP and GaAs substrates enabling us to make a direct comparison to the (In,Ga)As/GaAs quantum dot system. We also discuss the realization of quantum gates.

Soil transplants as a mine reclamation technique for rehabilitating soil microbial communities
Creators: name: Simard, S. (Suzanne)

Publisher: name: The University of British Columbia
Year: 2018

description: Overburden and tailings requiring reclamation at mine sites are nutrient deficient, have poor physical structure and lack developed biological communities, which can be a barrier to revegetation. Small-volume transplants of native forest soil to the seedling rhizosphere are a potential source of locally-adapted biological inoculum and improved rhizosphere physiochemical conditions. A six-month greenhouse study using substrates from the Mount Polley Mine, BC tested the effects of 5% (~40mL) and 25% (~180mL) native forest soil transplants on alder, spruce and willow seedling establishment in overburden and tailings. Sterilized soil was also tested to investigate the role of soil biota in the observed effects. In general, 5% and 25% forest soil transplants added to overburden and tailings, respectively, significantly improved seedling establishment to be equivalent to forest soil controls, although transplant effects and substrate interactions varied among the tested species. The transplants were also an effective source of nitrogen-fixing bacteria and ectomycorrhizal fungi for tailings reclamation. Increased colonization by these symbionts was linked to improvements in seedling growth and physiology endpoints. This reclamation technique provides an option for mine sites with low topsoil availability and/or salvaged topsoil that has degraded during long-term storage.

We study averaged expansion properties as a function of fundamental properties of the black holes, including the bare mass of the black holes and black hole spin. We then explore how closely the expansion properties correspond to properties of a corresponding matter-dominated FLRW universe. As residual radiation present in the initial data decays, we find good agreement with a matter-dominated FLRW solution, and the effective density in the volume is well-described by the horizon mass of the black hole.

For families of solutions with localized spatial support a self-similar solution is found at the boundary. For other families, we find that a static solution appears to sit at the boundary. This behavior is compared to the black hole critical phenomena found by Choptuik.

description: United States neoliberal ideology and three of its core values --lack of regulation, reliance on commodification, and companies' rent-seeking abilities-- contribute to the increase of contemporary prescription drug prices. Statistics and conclusions from economic and equity-based studies of large pharmaceutical corporations are used to further expand on the aforementioned three core values. Contrary to many statements made by pharmaceutical executives, substantial rents are able to be exploited under the guise of R&D costs. The findings of this paper conclude that high-grossing companies do not tend to offer any additional intellectual gain or innovation, but rather utilize tactics such as patent extensions and tax-based subsidies to privatize their profits.

Differently from typical industrial scenarios, with highly controlled environments, service robots must show an additional robustness to task perturbations and changes in the characteristics of their sensory feedback. In this paper, a robot is taught to perform two different cleaning tasks over a table, using a learning from demonstration paradigm. However, differently from other approaches, a convolutional neural network is used to generalize the demonstrations to different, not yet seen dirt or stain patterns on the same table using only visual feedback, and to perform cleaning movements accordingly. Robustness to robot posture and illumination changes is achieved using data augmentation techniques and camera images transformation. This robustness allows the transfer of knowledge regarding execution of cleaning tasks between heterogeneous robots operating in different environmental settings. To demonstrate the viability of the proposed approach, a network trained in Lisbon to perform cleaning tasks, using the iCub robot, is successfully employed by the DoRo robot in Peccioli, Italy.

description: A pathway to high Tc and Jc with superconducting hetero-nano structures of Tl-2223/Al are reported first time. Two dimensional nano-stripe structure at the interface of Tl-2223/Al was fabricated with room temperature electrochemical complexing technique. The confinement of the charge transport along the hetero-nano stripes at the interface was studied at different temperatures ranging from 300 K to 77 K. The high Jc along the interface at different temperatures is explained on the basis of Andreev reflections from the interface followed by confinement of charge transport along ab-plane (superconducting path) of Tl-2223 unit cell. The model has been proposed to explain the mechanism of high Tc and Jc observed at hetero-nano interface. The phenomenon of a pathway to high Tc and Jc with Tl-2223/Al hetero-nano interface was ascertained by destroying the interface by irradiating the heterostructure. * Author for correspondence

description: The adoption of game mechanics into serious contexts such as business applications (gamification) is a promising trend to improve the user’s participation and engagement with the software in question and on the job. However, this topic is mainly driven by practitioners. A theoretical model for gamification with appropriate empirical validation is missing. In this paper, we introduce a prototype for gamification using SAP ERP as example. Moreover, we have evaluated the concept within a comprehensive user study with 112 participants based on the technology acceptance model (TAM) using partial least squares (PLS) for analysis. Finally, we show that this gamification approach yields significant improvements in latent variables such as enjoyment, flow or perceived ease of use. Moreover, we outline further research requirements in the domain of gamification.

description: We use ultrasensitive electron backscatter diffraction (EBSD) to map the local crystal orientations, grains, and grain boundaries in CH3NH3PbI3 (MAPI) perovskite thin films. Although the true grain structure is broadly consistent with the morphology visible in scanning electron microscopy (SEM), the inverse pole figure maps taken with EBSD reveal grain structure and internal misorientation that is otherwise hidden. Local crystal misorientation is consistent with the presence of local strain which varies from one grain to the next. We acquire co-aligned confocal optical photoluminescence (PL) microscopy images on the same MAPI samples used for EBSD. We correlate optical and EBSD data, showing that PL is anticorrelated with the local grain orientation spread, suggesting that grains with higher degrees of crystalline orientational heterogeneity (local strain) exhibit more non-radiative recombination. We find that larger grains tend to have larger grain orientation spread, consistent with higher degrees of strain and non-radiative recombination.

The structural development of soil microbial communities in reclaimed sites of a metal mine : implications to the restoration of anthropogenic disturbances
Creators: name: Benson, L.
Publisher: name: The University of British Columbia
Year: 2018

description: Anthropogenic activities affect the structure of terrestrial systems, leading to diminished ecosystem functions. With the cumulative area of disturbance caused by mining in British Columbia approximating 45,412 ha, it is necessary to ensure that reclamation projects are directed by ecologically relevant objectives. In this study, phospholipid fatty acid analysis was used to compare the biomass of soil microbial communities in undisturbed reference and reclaimed sites. Similar to the development of microbial communities following natural disturbance events, microbial biomass within reclaimed sites increased through time, but was significantly lower than undisturbed forests until 30 to 45 years post reclamation. Canonical correspondence analysis identified that the differences in microbial community biomass was affected by changes in soil pH and copper. Due to the long-term requirements for soil development, the assessment of reclamation projects should exceed at least 30 years post completion to properly evaluate the recovery of soil ecosystem composition and function.

description: Nutzen durch den Einsatz von Informationstechnologie ist seit über 30 Jahren ein Schwerpunktthema der Forschung in der Wirtschaftsinformatik. Kontrovers diskutiert wird hierbei weniger die Existenz des betriebswirtschaftlichen Nutzens, als vielmehr Art und Umfang des Nutzens. Ein besonderes Augenmerk liegt auf der Frage, ob und inwieweit Unternehmen durch den Einsatz von Business Software Wettbewerbsvorteile generieren können. Anhand der Theorie der Positionierung und des Resource-based View untersucht dieser Beitrag, inwieweit der identifizierte Nutzen aus 13 ausgewählten Praxisprojekten zu (nachhaltigen) Wettbewerbsvorteilen führt oder lediglich zu erzielter Prozessexzellenz. Ein Ergebnis ist, dass die formalen Kriterien für die Existenz von Wettbewerbsvorteilen in den untersuchten Fallstudien erfüllt werden, während sie allerdings nur in Ausnahmefällen als nachhaltig bezeichnet werden können. Der Beitrag schließt mit einer kritischen Würdigung des Wettbewerbsvorteilsbegriffs und möglicher Taxonomien.

description: In the context of canonical quantum gravity in terms of Ashtekar's new variables, it is known that there exists a state that is annihilated by all the quantum constraints and that is given by the exponential of the Chern--Simons form constructed with the Asthekar connection. We make a first exploration of the transform of this state into the spin-network representation of quantum gravity. The discussion is limited to trivalent nets with planar intersections. We adapt an invariant of tangles to construct the transform and study the action of the Hamiltonian constraint on it. We show that the first two coefficients of the expansion of the invariant in terms of the inverse cosmological constant are annihilated by the Hamiltonian constraint. We also discuss issues of framing that arise in the construction.

description: This dissertation is a performance of, meditation on, and inquiry into the practice of close reading as it relates to the teaching, learning, and interpretation of literature. The objects of close reading include literature, the history of literary pedagogy and its relationship to critical theory, and a narrative that recounts my experience as an instructor of a teacher education course centered on literature and literary pedagogy. The seven chapters form a series of interlocking interpretive essays or “readings” that together raise questions about the relationship between aesthetic experiences with literary texts, the practice of literary interpretation, and pedagogical approaches in the literature classroom. The study is framed by an exploration of John Milton’s Paradise Lost and Mary Shelley’s Frankenstein, both of which, I argue, dramatize interpretive acts in ways that tacitly cue reading practices that would become familiar in twentieth-century literary and pedagogical theory. These two texts, the latter of which can be viewed as a “reading” of the former, provide a useful framework for conceptualizing literary knowledge as a kind of experiential knowledge, dramatizing Baconian empiricism and Coleridgean imagination in anticipation of twentieth-century theories of participatory aesthetics associated with I.A. Richards, John Dewey, and Louise Rosenblatt. Paradise Lost and Frankenstein also provide a testing ground for my own practice of close reading. At the heart of this study is a re-reading of the work of Rosenblatt and some of the New Critics: I argue that Rosenblatt and the New Critics, particularly Cleanth Brooks and Robert Penn Warren, were pioneers of parallel, rather than opposing, pedagogical traditions, informed by the shared influence of Richards and Dewey. I decouple a vision for an authentic practice of close reading—grounded in aesthetic experience and supported by meaningful interpretive discourse—from the narrower version of close reading promoted by the Common Core State Standards in literacy, which have been widely critiqued in ways that invite reductive accounts of literary history. Through a return to Rosenblatt and the New Critics, alongside a discussion of contemporary debates about the place of close reading in the literature classroom, I articulate principles of practice that could unite secondary and college teachers of literature and inform the teaching and learning of close reading in the twenty-first century. I conclude with a narrative in which I attempt to enact some of these principles in a literature course for teachers, offering a close reading of the tensions and discoveries that emerge in my own teaching.

description: A combinatorial condition is obtained for when immersed or embedded incompressible surfaces in compact 3-manifolds with tori boundary components remain incompressible after Dehn surgery. A combinatorial characterisation of hierarchies is described. A new proof is given of the topological rigidity theorem of Hass and Scott for 3-manifolds containing immersed incompressible surfaces, as found in cubings of non-positive curvature.

description: Systemnutzung stellt in der Nutzerakzeptanzforschung eine der wichtigsten abhängigen Variablen dar. In vielen Akzeptanzstudien ergeben sich jedoch Probleme bei ihrer Erhebung. Manche Forscher weichen daher auf eine Selbsteinschätzung der Nutzer bzgl. der System-nutzung aus, d.h. sie messen diese nicht auf Basis einer objektiv bestimmbaren Größe. Andere beschränken sich in ihren Studien auf die Nutzungsintention als abhängige Variable anstelle der Systemnutzung und stützen sich dabei implizit auf die Annahme, dass Nutzungs-intention ein geeigneter Prädiktor für Systemnutzung sei. Diese Annahme wird in diesem Beitrag auf Basis von Daten zweier Studien überprüft und bestätigt. Akzeptanzforschern kann daher empfohlen werden, mit Nutzungsintention als abhängiger Variable zu arbeiten. Ein Ausweichen auf die häufig kritisch bewertete Selbsteinschätzung scheint somit überflüssig.
