description: Central to most applications involving monolayer graphene is its mechanical response under various stress states. To date most of the work reported is of theoretical nature and refers to tension and compression loading of model graphene. Most of the experimental work is indeed limited to bending of single flakes in air and the stretching of flakes up to typically ~1% using plastic substrates. Recently we have shown that by employing a cantilever beam we can subject single graphene into various degrees of axial compression. Here we extend this work much further by measuring in detail both stress uptake and compression buckling strain in single flakes of different geometries. In all cases the mechanical response is monitored by simultaneous Raman measurements through the shift of either the G or 2D phonons of graphene. In spite of the infinitely small thickness of the monolayers, the results show that graphene embedded in plastic beams exhibit remarkable compression buckling strains. For large length (l)-to-width (w) ratios (> 0.2) the buckling strain is of the order of -0.5% to -0.6%. However, for l/w <0.2 no failure is observed for strains even higher than -1%. Calculations based on classical Euler analysis show that the buckling strain enhancement provided by the polymer lateral support is more than six orders of magnitude compared to suspended graphene in air.

description: We demonstrate that persistent current in meso- and nanorings may fluctuate down to zero temperature provided the current operator does not commute with the total Hamiltonian of the system. For a model of a quantum particle on a ring we explicitly evaluate PC noise power which has a form of sharp peaks which become broadened for multi-channel rings or in the presence of dissipation. PC noise can be tuned by an external magnetic flux which is a fundamental manifestation of quantum coherence in the system.

Investigation into bond strength between EDCC/masonry
Creators: name: Yan, Yuan
Publisher: name: University of British Columbia
Year: 2016

description: In order to apply Sprayable Eco-Friendly Ductile Cementitious Composites (EDCC) as a thin overlay material for masonry building upgrade, this study aims at understanding one of the key issues of repair: bond strength between old structure and the new repair overlay. Several influencing factors on bond strength were investigated, including repair thickness, fiber addition, substrate properties, curing age and environment. Bond strength was measured by tensile pull-off and friction-transfer tests. At the conclusion of the research, EDCC was able to achieve satisfactory bond strength provided sufficient penetrability into the substrate, even under field conditions and without curing. Fibers added into EDCC impact bond strength negatively, if they are oriented parallel to the interface as a result of manual casting or if there is a low fractal dimension of the substrate surface. Further, 56 days can be used as the maturity age of bond strength with EDCC overlay. In future applications, penetrability of EDCC overlays can be ensured through sufficient amount of superplasticizer or energy of casting. For example, EDCC with 150mm slump was able to satisfy standard bond strength requirement of concrete in the field, at the age of 45 days. Penetrability of EDCC overlay is of vital importance, since EDCC with low workability (0 slump) can’t achieve requirement of structural repair even under standard curing. To mitigate the negative effect of fiber addition on bond strength, higher substrate roughness and 3D fiber orientation can be of help, through proper surface roughness preparation and the use of spray methods (e.g., shotcrete) instead of hand application. For further study, it is suggested that measures should be taken to obtain more pure bond strength values for simplification of analysis. Also surface roughness variation and long term properties of interface are worth investigation, once proper substrates are chosen for lab research.

Water grabbing and conflict in the Nile River basin : a focus on Ethiopia
Creators: name: Crego Liz, Eva
Publisher: name: University of British Columbia
Year: 2016

description: The phenomenon of large-scale land investments for agricultural production – also referred to as land grabbing – has grown in recent years all over the world, especially after the 2007-2008 international food price crisis. Ethiopia is among the most targeted countries by foreign investors concerning farmland demand. But not only that, the Ethiopian Government is actively promoting and encouraging private sector participation in large-scale farming, especially in the low land border areas of the country that are part of the Ethiopian Nile River basin. The development of land transferred to investors in these areas will necessarily result in an increase of Ethiopia’s Nile waters use. The intensification of Nile waters consumption in Ethiopia, in turn, may challenge the existing arrangement at the basin level, where Egypt has historically acted as the hydro-hegemon opposing any water resources development in the upstream countries. Thus, in this research I explore the implications of land grabbing on water resources as well as the ways in which specific ideas about water configure different power geometries at different scales. By using the agronomic model CROPWAT, I estimate the amount of water required to bring into production all the land that has been transferred to investors in the Ethiopian Nile River basin. Results from CROPWAT show that large-scale farming development could increase the pressure on water resources in some areas to unsustainable levels, as it is the case of the Pibor – Akabo – Sobat sub-basin. It could represent as well, a decline up to 3.4 % of Egypt’s Nile waters share – up to 10.2% in the case of Sudan – clearly challenging the existing hydro-hegemony in the basin. Furthermore, by interrogating different notions of water – those of the state, private investors and local communities – through the hydrosocial cycle framework, this research reveals how water discourses configure social structures and power relations at different scales; and how water injustices reveal or conceal themselves depending on the scale of inquiry.
Bouncing universe for deformed non-minimally coupled inflation model

Year: 2023
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: In this paper, we consider a non-minimally coupled gravity model to study the bouncing universe. The holographic principle has various effects on the bouncing universe. We choose some suitable new variables and achieve the new Hamiltonian and Lagrangian which have harmonic oscillator form. The corresponding Lagrangian is deformed by non-commutative geometry. In order to have a solution for the bouncing universe we specify the potential in the equation state. In that case, we draw the equation of state in terms of time and show that the equation of state crosses $-1$. Such bouncing behavior leads us to apply some conditions on $θ$ and $β$ from non-commutative geometry. Here, we can also check the system's stability due to the deformation of the non-minimally coupled gravity model. In order to examine the stability of the system we obtain the variation of pressure with respect to density energy. Also, we draw the variation of pressure with respect to energy density and show the stability condition.

description: Quantum information science addresses how uniquely quantum mechanical phenomena such as superposition and entanglement can enhance communication, information processing and precision measurement. Photons are appealing for their low noise, light-speed transmission and ease of manipulation using conventional optical components. However, the lack of highly efficient optical Kerr nonlinearities at single photon level was a major obstacle. In a breakthrough, Knill, Laflamme and Milburn (KLM) showed that such an efficient nonlinearity can be achieved using only linear optical elements, auxiliary photons, and measurement. They proposed a heralded controlled-NOT (CNOT) gate for scalable quantum computation using a photonic quantum circuit to combine two such nonlinear elements. Here we experimentally demonstrate a KLM CNOT gate. We developed a stable architecture to realize the required four-photon network of nested multiple interferometers based on a displaced-Sagnac interferometer and several partially polarizing beamsplitters. This result confirms the first step in the KLM `recipe' for all-optical quantum computation, and should be useful for on-demand entanglement generation and purification. Optical quantum circuits combining giant optical nonlinearities may find wide applications across telecommunications and sensing.

description: Person Re-ID has been gaining a lot of attention and nowadays is of fundamental importance in many camera surveillance applications. The task consists of identifying individuals across multiple cameras that have no overlapping views. Most of the approaches require labeled data, which is not always available, given the huge amount of demanded data and the difficulty of manually assigning a class for each individual. Recently, studies have shown that re-ranking methods are capable of achieving significant gains, especially in the absence of labeled data. Besides that, the fusion of feature extractors and multiple-source training is another promising research direction not extensively exploited. We aim to fill this gap through a manifold rank aggregation approach capable of exploiting the complementarity of different person Re-ID rankers. In this work, we perform a completely unsupervised selection and fusion of diverse ranked lists obtained from multiple and diverse feature extractors. Among the contributions, this work proposes a query performance prediction measure that models the relationship among images considering a hypergraph structure and does not require the use of any labeled data. Expressive gains were obtained in four datasets commonly used for person Re-ID. We achieved results competitive to the state-of-the-art in most of the scenarios.
Application of ammonium-citrate-thiosulfate leaching on awaruite-bearing serpentinite ores
Creators: name: Wei, Wei
Publisher: name: University of British Columbia
Year: 2016

description: Nickel is an important alloying element of stainless steel and non-ferrous alloys. Awaruite as an alternative nickel source is gaining attention at the depletion of sulfide nickel and the high cost of laterite nickel, which are traditional nickel resources. In view of the absence of a nickel recovery method from awaruite resources, UBC hydrometallurgy laboratory developed an in-house hydrometallurgical technology of atmospheric leaching in ammonium-citrate-thiosulfate solution. Ammonium selectively dissolves nickel in the presence of oxygen while citrate acts as a ferric chelator and thiosulfate a depassivation agent of nickel-iron alloy. In order to prepare the technology for pilot testing, in-depth batch leaching tests as well as preliminary solvent extraction tests were conducted and reported in this study. The leaching tests on an alternative source had an optimized result of ~85% nickel extraction. The nickel leaching reactions were believed under surface reaction control as indicated by the estimated activation energy of 54.4kJ/mol through kinetic model fitting of leaching test data. However, the leaching tests with high pulp density (>10%) and recycled liquor simulating industrial settings demonstrated hindered nickel extraction due to iron accumulation. Specifically, a targeted comparison test showed that in order to retain 80% nickel extraction at 30% pulp density, simultaneous increases to four times the original ammonia concentration and six times the original citrate concentration are required in comparison with the 10% pulp density baseline test. Therefore, this technology needs to be improved on iron removal and economical leach reagents recycle for commercialization. In the solvent extraction study, ACORGA K2000 as an ideal reagent candidate based on hydroxyoxime was tested on synthetic PLS containing 1 g/L Nickel (II), 0 – 0.8 g/L Fe (III), 0.1 – 0.5 M citrate and 1.5 – 6 M total ammonia. Hydroxyoxime has been proven effective in separating base metals from ammoniacal media. Results revealed that complete separation of nickel from iron was achieved at 5 v/o reagent solution concentration. Nickel can also be readily eluted with diluted sulfuric acid at pH = 1. The extraction kinetics was found to be relatively slow with 30 min of mixing/settling time required to reach equilibrium.

The known high pressure ice phases VII, VIII, X, and Pbcm as well as the Pbca phase are all insulating and composed of two interpenetrating hydrogen bonded networks, but the Cmcm structure is metallic and consists of corrugated sheets of H and O atoms. The H atoms are squeezed into octahedral positions between next-nearest O atoms while they occupy tetrahedral positions between nearest O atoms in the ice X, Pbcm, and Pbca phases.

description: This paper introduces a new framework of fast and efficient sensing matrices for practical compressive sensing, called Structurally Random Matrix (SRM). In the proposed framework, we pre-randomize a sensing signal by scrambling its samples or flipping its sample signs and then fast-transform the randomized samples and finally, subsample the transform coefficients as the final sensing measurements. SRM is highly relevant for large-scale, real-time compressive sensing applications as it has fast computation and supports block-based processing. In addition, we can show that SRM has theoretical sensing performance comparable with that of completely random sensing matrices. Numerical simulation results verify the validity of the theory as well as illustrate the promising potentials of the proposed sensing framework.

This leads to dimensional reduction theorems for differentiation and integration in superspace. These spherically symmetric functions can be used to solve orthosymplectically invariant Schroedinger equations in superspace, such as the (an)harmonic oscillator or the Kepler problem. Finally the obtained machinery is used to prove the Funk-Hecke theorem and Bochner's relations in superspace.

description: We have investigated a time series of continuum intensity maps and corresponding Dopplergrams of granulation in a very quiet solar region at the disk center, recorded with the Imaging Magnetograph eXperiment (IMaX) on board the balloon-borne solar observatory Sunrise. We find that granules frequently show substructure in the form of lanes composed of a leading bright rim and a trailing dark edge, which move together from the boundary of a granule into the granule itself. We find strikingly similar events in synthesized intensity maps from an ab initio numerical simulation of solar surface convection. From cross sections through the computational domain of the simulation, we conclude that these `granular lanes' are the visible signature of (horizontally oriented) vortex tubes. The characteristic optical appearance of vortex tubes at the solar surface is explained. We propose that the observed vortex tubes may represent only the large-scale end of a hierarchy of vortex tubes existing near the solar surface.

description: Core-collapse supernovae (CC SNe), especially Type II-Plateau ones, are thought to be important contributors to cosmic dust production. SN 2004dj, one of the closest and brightest SN since 1987A, offered a good opportunity to examine dust formation processes. To find signs of newly formed dust, we analyze all available mid-infrared (MIR) archival data from the Spitzer Space Telescope. We re-reduce and analyze data from IRAC, MIPS and IRS instruments obtained between +98 and +1381 days after explosion, generating light curves and spectra for each epoch. Observed spectral energy distributions are fitted with both analytic and numerical models, using the radiative-transfer code MOCASSIN for the latter ones. We also use imaging polarimetric data obtained at +425 days by the Hubble Space Telescope. We present convincing evidence of dust formation in the ejecta of SN 2004dj from MIR light curves and spectra. Significant MIR excess flux is detected in all bands between 3.6 and 24 um. In the optical, a ~0.8% polarization is also detected at a 2-sigma level, which exceeds the interstellar polarization in that direction. Our analysis shows that the freshly-formed dust around SN 2004dj can be modeled assuming a nearly spherical shell containing amorphous carbon grains, cooling from ~700 K to ~400 K between +267 and +1246 days. Persistent excess flux has been found above 10 um, which is explained by a cold (~115 K) dust component. If this cold dust is of circumstellar origin, it is likely to be condensed in a cool, dense shell between the forward and reverse shocks. Pre-existing circumstellar dust is less likely, but cannot be ruled out. An upper limit of ~8x10^{-4} M_sun was derived for the dust mass, which is similar to previously published values for other dust-producing SNe.

description: Assuming that supernovae type Ia (SNe Ia) are standard candles one could use them to test cosmological theories. The Hubble Space Telescope team analyzed 186 SNe Ia\cite{Riess_04} to test the Standard Cosmological model (SC) associated with expanded lengths in the Universe and evaluate its parameters. We use the same sample to determine parameters of Conformal Cosmological model (CC) with relative reference units of intervals, so that conformal quantities of General Relativity are interpreted as observables. We concluded, that really the test is extremely useful and allows to evaluate parameters of the model. From a formal statistical point of view the best fit of the CC model is almost the same quality approximation as the best fit of SC model with $Ω_Λ=0.72, Ω_m=0.28$. As it was noted earlier, for CC models, a rigid matter component could substitute the $Λ$-term (or quintessence) existing in the SC model. We note that a free massless scalar field can generate such a rigid matter. We describe results of our analysis for more recent "gold" data (for 192 SNe Ia).

Transcriptome-based analysis of molecular pathways for clusterin functions in kidney cells
Creators: name: Dairi, Ghida Saleh
Publisher: name: University of British Columbia
Year: 2016

description: Background: Clusterin (CLU) is a chaperone-like protein. Our previous studies have demonstrated that CLU protects kidney from ischemia-reperfusion injury (IRI) and enhances renal repair after IRI; however, the molecular pathways for its functions in the kidney are not fully understood. This study was designed to investigate CLU-mediating pathways in kidney cells by using bioinformatics analysis. Materials and Methods: An in vitro model of kidney tissue using CLU null renal tubular epithelial cells (TECs) was established for this research project. An immortalized CLU null TEC cell line was generated from a CLU knockout (KO) mouse, and was stably expressing pHEX6300 plasmid containg human CLU cDNA (TEC-CLUhCLU), so that this cell line constitutively expresses human CLU protein, whereas control cell line (TEC-CLU-/-) was generated from the same parental CLU null TEC cell line by expressing empty pHEX6300. Both TEC-CLUhCLU and TEC-CLU-/- cell lines were exposed to either normoxia or hypoxia (1% O2). Transcriptome profiling with a significant 2-fold change (FC) (FC ≥ 2, p ≤ 0.05) was performed using SurePrint G3 Mouse Gene Expression 8×60K microarray, and the signaling pathways was ranked by using Ingenuity pathway analysis (IPA). Results: Here, we showed that compared to CLU null TEC-CLU-/- controls ectopic expression of human CLU in CLU null kidney cells (TEC-CLUhCLU) promoted cell growth but inhibited migration in normoxia, and enhanced cell survival in hypoxia. CLU affected expression of 3864 transcripts (1893 up-regulated) in normoxia and 3670 transcripts (1925 up-regulated) in hypoxia. CLU functions including cell proliferation, survival and adhesion in normoxia were associated mostly with AKT2 dependent PI3K/AKT, PTEN, VEGF and ERK/MAPK signaling and as well with GSK3B-mediated cell cycle progression. In addition to unfolded protein response (UPR) and/or endoplasmic reticulum (ER) stress, CLU-enhanced cell survival in hypoxia was also associated with Foxo3/PIK3CD/MAPK1-dependent PI3K/AKT, HIF-α, PTEN, VEGF and ERK/MAPK signaling. Conclusion: Our data showed that CLU functions in kidney cells were mediated in a cascade manner mainly by PI3K/AKT, PTEN, VEGF and ERK/MAPK signaling, and specifically by activation of UPR/ER stress in hypoxia, providing new insights into the protective role of CLU in the kidney.

description: A symmetric matrix is called a Laplacian if it has nonpositive off-diagonal entries and zero row sums. Since the seminal work of Spielman and Teng (2004) on solving Laplacian linear systems in nearly linear time, several algorithms have been designed for the task. Yet, the work of Kyng and Sachdeva (2016) remains the simplest and most practical sequential solver. They presented a solver purely based on random sampling and without graph-theoretic constructions such as low-stretch trees and sparsifiers. In this work, we extend the result of Kyng and Sachdeva to a simple parallel Laplacian solver with $O(m \log^3 n \log\log n)$ or $O((m + n\log^5 n)\log n \log\log n)$ work and $O(\log^2 n \log\log n)$ depth using the ideas of block Cholesky factorization from Kyng et al. (2016). Compared to the best known parallel Laplacian solvers that achieve polylogarithmic depth due to Lee et al. (2015), our solver achieves both better depth and, for dense graphs, better work.
Hydrometeorology and streamflow response during rain-on-snow events in a coastal mountain region

description: Rain-on-snow, in which rainfall occurs upon a previously existing snowpack, complicates runoff response to rain events. In some situations the snowpack absorbs rainfall; in others, runoff is enhanced by significant snowmelt. Rain-on-snow has generated major floods around the world, particularly in coastal, mountainous regions such as southwestern British Columbia, where the rugged topography can cause rapid and varying transitions between rainfall and snowfall within the same watershed, and warm, subtropical storms known as atmospheric rivers can deliver large quantities of precipitation. This thesis sought to further the understanding of rain-on-snow at the regional scale, including its role in runoff response to a wide spectrum of rain-on-snow events. Tools were developed and assessed to help achieve this goal and for use by others. First, the hydrologic utility of output from a regional weather reanalysis model was tested. Results showed air temperature and vapour pressure were likely to be useful, whereas other variables were not accurate enough to be of use. Air temperature, in particular, showed potential ability for more accurate specification of temperature gradients for hydrologic forecasting of rain-on-snow runoff. An analysis of rain-on-snow events across five automated snow pillow sites over 10 years illustrated the importance of understanding the amount of rainfall occurring at high elevations during rain-on-snow, and the relatively consistent enhancement of water available for runoff (WAR) by 25-30% due to snowmelt during large rain-on-snow events. For smaller events, a range of antecedent and meteorological factors influenced WAR generation, particularly the antecedent liquid water content of the snowpack. A probabilistic method for infilling cloud obscured pixels in optical remotely sensed snow cover imagery showed strong performance compared to more standard methods, and illustrated spatial changes in snow cover during the largest flood event within the analysis period. This method was developed to maximize information gain from satellite snowcover imagery while minimizing the transfer of disinformation. Finally, high elevation rainfall during atmospheric river events was found to be the dominant predictor of runoff response in six study catchments in the region. Antecedent snowcover provided only minimal increases in the ability to predict runoff during these events compared to rainfall alone.

Thermodynamic and dynamic anomalies in a one dimensional lattice model of liquid water

description: We investigate the occurrence of waterlike thermodynamic and dynamic anomalous behavior in a one dimensional lattice gas model. The system thermodynamics is obtained using the transfer matrix technique and anomalies on density and thermodynamic response functions are found. When the hydrogen bond (molecules separated by holes) is more attractive than the van der Waals interaction (molecules in contact) a transition between two fluid structures is found at null temperature and high pressure. This transition is analogous to a `critical point' and intimately connects the anomalies in density and in thermodynamic response functions. Monte Carlo simulations were performed in the neighbourhood of this transition and used to calculate the self diffusion constant, which increases with density as in liquid water.

description: Size-selective mortality due to harvesting is a threat to numerous exploited species, but how it affects the ecosystem remains largely unexplored. Here, we used a pond mesocosm experiment to assess how evolutionary responses to opposite size-selective mortality interacted with the environment (fish density and light intensity used as a proxy of resource availability) to modulate fish populations, prey community composition and ecosystem functions. We used medaka (Oryzias latipes) previously selected over 10 generations for small size (harvest-like selection; small-breeder line) or large size (large-breeder line), which displayed slow somatic growth and early maturity or fast somatic growth and late maturity, respectively. Large-breeder medaka produced more juveniles, which seemed to grow faster than small-breeder ones but only under high fish density. Additionally, large-breeder medaka had an increased impact on some benthic prey, suggesting expanded diet breadth and/or enhanced foraging abilities. As a consequence, increased light stimulated benthic algae biomass only in presence of large-breeder medaka, which were presumably better at controlling benthic grazers. Aggregated effect sizes at the community and ecosystem levels revealed that the ecological effects of medaka evolution were of similar magnitude than those induced by the environment and fish introduction. These findings indicate the important environmental dependency of evolutionary response to opposite size-selective mortality on higher levels of biological organizations.

description: In this contribution, we introduce numerical continuation methods and bifurcation theory, techniques which find their roots in the study of dynamical systems, to the problem of tracing the parameter dependence of bound and resonant states of the quantum mechanical Schrödinger equation. We extend previous work on the subject to systems of coupled equations. Bound and resonant states of the Schrödinger equation can be determined through the poles of the S-matrix, a quantity that can be derived from the asymptotic form of the wave function. We introduce a regularization procedure that essentially transforms the S-matrix into its inverse and improves its smoothness properties, thus making it amenable to numerical continuation. This allows us to automate the process of tracking bound and resonant states when parameters in the Schrödinger equation are varied. We have applied this approach to a number of model problems with satisfying results.

description: By controlling the temporal and spatial features of light, we propose a novel protocol to prepare two-qubit entangling gates on atoms trapped at close distance, which could potentially speed up the operation of the gate from the sub-micro to the nanosecond scale. The protocol is robust to variations in the pulse areas and the position of the atoms, by virtue of the coherent properties of a dark state, which is used to drive the population through Rydberg states. From the time-domain perspective, the protocol generalizes the one proposed by Jaksch and coworkers [Jaksch et al., Phys. Rev. Lett. 85, 2208 (2000)], with three pulses that operate symmetrically in time, but with different pulse areas. From the spatial-domain perspective, it uses structured light. We analyze the map of the gate fidelity, which forms rotated and distorted lattices in the solution space. Finally, we study the effect of an additional qubit to the gate performance and propose generalizations that operate with multi-pulse sequences.
