Sediment transport and channel morphology of small alluvial channels
Creators: name: Al-Ghorani, Nisreen
Publisher: name: University of British Columbia
Year: 2023

description: A number of geomorphological and hydrological factors interact at multiple scales to control sediment transport processes and the resulting morphology of river channels. Predicting how these channels will adjust in response to climate and land-use change requires a thorough understanding of these processes at multiple spatiotemporal scales. Researchers’ ability to investigate these processes at multiple scales has been limited by the dearth of comprehensive long-term sediment monitoring programs. To address this gap, this thesis examines the spatial and time dependence of sediment transport and channel morphodynamics using a 20-year detailed dataset from Goodwin Creek, Mississippi (USA). To examine the timescale dependence of fine sediment transport, we apply wavelet transforms to time series of streamflow, suspended sediment concentration, and sediment load for 11 monitoring stations at Goodwin Creek, with each sub-watershed representing a different land-use and channel boundary condition. We find that although reduced cultivation has caused a decline in fine sediment transport across all time scales, the degree of this decline is considerably influenced by the composition of streambed, and the presence of physiographic features (e.g., gullies, ponds). Over longer timescales, the wavelet transforms suggest that sediment supply shifts from readily accessible to more distant sources. To examine the dependence of spatial scale on sediment transport, we construct sediment budgets for fines, sand, and gravel for two adjacent reaches with contrasting morphological settings. We demonstrate that along-channel variations in gravel and sand storage are controlled by sediment availability within the channel. Substantial changes in fine sediment storage, however, occur during medium magnitude, long-duration flood events. The effectiveness of these events was determined by riverbank stability and near-bank sediment storage inherited from historical flows. Finally, we examine the spatial dependence of bedload transport at the sub-reach scale using a 2D hydraulic model to estimate spatial distributions of shear stress and calculate fractional sediment mobility at East Creek, British Columbia. Results from this model indicate that sediment transport is highly localized and sporadic during low to moderate flows due to the influence of channel morphology.

description: The stochastic differential equation (SDE)-based random process models of volatile renewable energy sources (RESs) jointly capture the evolving probability distribution and temporal correlation in continuous time. It has enabled recent studies to remarkably improve the performance of power system dynamic uncertainty quantification and optimization. However, considering the non-homogeneous random process nature of PV, there still remains a challenging question: how can a realistic and accurate SDE model for PV power be obtained that reflects its weather-dependent uncertainty in online operation, especially when high-resolution numerical weather prediction (NWP) is unavailable for many distributed plants? To fill this gap, this article finds that an accurate SDE model for PV power can be constructed by only using the cheap data from low-resolution public weather reports. Specifically, an hourly parameterized Jacobi diffusion process is constructed to recreate the temporal patterns of PV volatility during a day. Its parameters are mapped from the public weather report using an ensemble of extreme learning machines (ELMs) to reflect the varying weather conditions. The SDE model jointly captures intraday and intrahour volatility. Statistical examination based on real-world data collected in Macau shows the proposed approach outperforms a selection of state-of-the-art deep learning-based time-series forecast methods.

description: Integrating out fast degrees of freedom is known to yield, to a good approximation, memory-less, i.e. Markovian, dynamics. In the presence of such a time-scale separation local detailed balance is believed to emerge and to guarantee thermodynamic consistency arbitrarily far from equilibrium. Here we present a transparent example of a Markov model of a molecular motor where local detailed balance can be violated despite a clear time-scale separation and hence Markovian dynamics. Driving the system far from equilibrium can lead to a violation of local detailed balance against the driving force. We further show that local detailed balance can be restored, even in the presence of memory, if the coarse-graining is carried out as Milestoning. Our work establishes Milestoning not only as a kinetically but for the first time also as a thermodynamically consistent coarse-graining method. Our results are relevant as soon as individual transition paths are appreciable or can be resolved.

description: Using first-principles electronic structure calculations, we have studied the dependence of the Curie temperature on external hydrostatic pressure for random Ni2MnSn Heusler alloys doped with Cu and Pd atoms, over the entire range of dopant concentrations. The Curie temperatures are calculated by applying random-phase approximation to the Heisenberg Hamiltonian whose parameters are determined using the linear response and multiple scattering methods, based on density-functional theory. In (Ni1-x,Pdx)2MnSn alloys, the Curie temperature is found to increase with applied pressure over the whole concentration range. The crossover from the increase to the decrease of the Curie temperature with pressure takes place for Cu concentrations larger than about 70% in (Ni1-x,Cux)2MnSn Heusler alloys. The results for the reference Ni2MnSn Heusler alloy agree well with a previous theoretical study of E. Sasioglu, L. M. Sandratskii and P. Bruno Phys. Rev. B 71 214412 (2005) and also reasonably well with available experimental data. Results for the spin-disorder-induced part of the resistivity in (Ni1-x,Pdx)2MnSn Heusler alloys, calculated by using the disordered local moment model, are also presented. Finally, a qualitative understanding of the results, based on Anderson's superexchange interaction and Stearn's model of the indirect exchange interaction between localized and itinerant d electrons, is provided.

description: An \emph{antilattice} is an algebraic structure based on the same set of axioms as a lattice except that the two commutativity axioms for $\land$ and $\lor$ are replaced by anticommutative counterparts. In this paper we study certain classes of antilattices, including elementary (no nontrivial subantilattices), odd (no subantilattices of order $2$), simple (no nontrivial congruences) and irreducible (not expressible as a direct product). In the finite case, odd antilattices are the same as Leech's \emph{Latin} antilattices which arise from the construction of semimagic squares from pairs of orthogonal Latin squares.

description: Heute sind etwa ein Viertel aller Professuren an deutschen Hochschulen mit Frauen besetzt (GWK 2021). Die Steigerungen des Anteils an Frauen auf Professuren gehen im Wesentlichen auf die umfassenden Förderprogramme, vor allem das Professorinnenprogramm des Bundes und der Länder zurück. Eine Fortsetzung dieser Anstrengungen zur Erreichung von Geschlechterparität steht derzeit auf der politischen Agenda.

Die Geschlechterforschung hat sich in den letzten beiden Jahrzehnten u.a. intensiv mit den Barrieren für Wissenschaftlerinnen insbesondere auf dem Weg zur Professur beschäftigt (vgl. etwa Metz-Göckel 2007; Kahlert 2013). Deutlich weniger Beachtung fand hingegen die Frage, wie es um die Situation von Frauen im Hochschulsystem nach erfolgreicher Berufung auf eine Lebenszeitprofessur bestellt ist. Daher haben wir mittels einer empirischen Interviewstudie die (Arbeits-)Situation von Professor:innen an deutschen Universitäten, Hochschulen für Angewandte Wissenschaft (HAW) sowie Kunst- und Musikhochschulen untersucht. Dabei zeigte sich, dass auch jenseits der Gläsernen Decke der Lebenszeitprofessur geschlechterbasierte Asymmetrien bestehen bleiben (Wagner et al. 2021).

description: Viewing the BRAID invariant as a generator of link Floer homology we generalise work of Baldwin-Vela-Vick to obtain rank bounds on the next to top grading of knot Floer homology. These allow us to classify links with knot Floer homology of rank at most eight, and prove a variant of a classification of links with Khovanov homology of low rank due to Xie-Zhang. In another direction we use a variant of Ozsváth-Szabó classification of $E_2$ collapsed $\mathbb{Z} \oplus\mathbb{Z}$ filtered chain complexes to show that knot Floer homology detects $T(2,8)$ and $T(2,10)$. Combining these techniques with the spectral sequences of Batson-Seed, Dowlin, and Lee we can show that Khovanov homology likewise detects $T(2,8)$ and $T(2,10)$.

Poling of barium titanate nanoparticles-incorporated piezoelectric paper substrates

Publisher: name: University of British Columbia
Year: 2023

description: Paper manufacturing is a strategic industry for Canada. However, rapidly changing markets, weak prices, increasing transportation costs, frequent wildfires, and recent mill closures have significantly impacted the pulp and paper industry. According to Canadian Industry Statistics, in British Columbia alone, the gross domestic product contribution from pulp and paper industry has declined by more than 25% from 2018 to 2020. Developing paper-based composites for specialized applications such as transducers will open new markets for pulp and paper industry. Incorporating piezoelectric particles in paper matrices leads to composites that can be employed as piezoelectric transducers whilst retaining the intrinsic properties of paper such as porosity and flexibility. Yet, to impart piezoelectric properties, these composites need to be electrically poled. This research project focuses on corona poling of 300 nm barium titanate nanoparticles incorporated paper based piezoelectric composites manufactured using unrefined and refined Northern Bleached Softwood Kraft (NBSK) pulp. The highest piezoelectric charge constant of 37.2 pC/N (comparable to commercially available polymers such as PVdF) was obtained for the composite manufactured using 300 kWh/t refined NBSK pulp with a barium titanate mass loading of 69.3 wt.%. This was attributed to increased surface roughness of fibers and enhanced stress transfer within the compact paper matrix formed due to refining, and enhanced polarization paths due to nanoparticle clusters within the paper composite. Best poling conditions were identified based on the studies on the effects of grid voltage in the corona triad, poling temperature, and poling time on the piezoelectric response. The observed decay in piezoelectric response of the composite over time was attributed to the dielectric contrast in constituent materials in the composite, hindrance to domain motion due to particle size, and depolarization fields caused by space charges. Findings of this work can be transferred to develop practical applications of barium titanate nanoparticles-incorporated paper-based piezoelectric composites such as tactile sensors, accelerometers, and smart packaging systems.

description: We introduce a Green function and analogues of other related kernels for finite and infinite networks whose edge weights are complex-valued admittances with positive real part. We provide comparison results with the same kernels associated with corresponding reversible Markov chains, i.e., where the edge weights are positive. Under suitable conditions, these lead to comparison of series of matrix powers which express those kernels. We show that the notions of transience and recurrence extend by analytic continuation to the complex-weighted case even when the network is infinite. Thus, a variety of methods known for Markov chains extend to that setting.

description: Variational quantum eigensolver (VQE) is regarded as a promising candidate of hybrid quantum-classical algorithm for the near-term quantum computers. Meanwhile, VQE is confronted with a challenge that statistical error associated with the measurement as well as systematic error could significantly hamper the optimization. To circumvent this issue, we propose classically-optimized VQE (co-VQE), where the whole process of the optimization is efficiently conducted on a classical computer. The efficacy of the method is guaranteed by the observation that quantum circuits with a constant (or logarithmic) depth are classically tractable via simulations of local subsystems. In co-VQE, we only use quantum computers to measure nonlocal quantities after the parameters are optimized. As proof-of-concepts, we present numerical experiments on quantum spin models with topological phases. After the optimization, we identify the topological phases by nonlocal order parameters as well as unsupervised machine learning on inner products between quantum states. The proposed method maximizes the advantage of using quantum computers while avoiding strenuous optimization on noisy quantum devices. Furthermore, in terms of quantum machine learning, our study shows an intriguing approach that employs quantum computers to generate data of quantum systems while using classical computers for the learning process.

description: Systems consisting of spheres rolling on elastic membranes have been used to introduce a core conceptual idea of General Relativity (GR): how curvature guides the movement of matter. However, such schemes cannot accurately represent relativistic dynamics in the laboratory because of the dominance of dissipation and external gravitational fields. Here we demonstrate that an ``active" object (a wheeled robot), which moves in a straight line on level ground and can alter its speed depending on the curvature of the deformable terrain it moves on, can exactly capture dynamics in curved relativistic spacetimes. Via the systematic study of the robot's dynamics in the radial and orbital directions, we develop a mapping of the emergent trajectories of a wheeled vehicle on a spandex membrane to the motion in a curved spacetime. Our mapping demonstrates how the driven robot's dynamics mix space and time in a metric, and shows how active particles do not necessarily follow geodesics in the real space but instead follow geodesics in a fiducial spacetime. The mapping further reveals how parameters such as the membrane elasticity and instantaneous speed allow the programming of a desired spacetime, such as the Schwarzschild metric near a non-rotating blackhole. Our mapping and framework facilitate creation of a robophysical analog to a general relativistic system in the laboratory at low cost that can provide insights into active matter in deformable environments and robot exploration in complex landscapes.

description: Hyperspectral imaging is increasingly used for product monitoring in industrial processes. Spectral unmixing is an important task in this context. As in many other areas of signal processing, neural networks also provide promising results for spectral unmixing. Unfortunately, it is very time-consuming to prepare labelled training data for the neural networks. To address this problem, this paper presents a method where small training datasets are augmented to improve spectral unmixing performance. Inspired by Gaussian processes, simple neural networks are trained which are capable of generating additional training data. These are similar to the original training data but cover areas in the continuous label space that are not covered by the original data.
System-size convergence of point defect properties: The case of the silicon vacancy

description: We present a comprehensive study of the vacancy in bulk silicon in all its charge states from 2+ to 2-, using a supercell approach within plane-wave density-functional theory, and systematically quantify the various contributions to the well-known finite size errors associated with calculating formation energies and stable charge state transition levels of isolated defects with periodic boundary conditions. Furthermore, we find that transition levels converge faster with respect to supercell size when only the Gamma-point is sampled in the Brillouin zone, as opposed to a dense k-point sampling. This arises from the fact that defect level at the Gamma-point quickly converges to a fixed value which correctly describes the bonding at the defect centre. Our calculated transition levels with 1000-atom supercells and Gamma-point only sampling are in good agreement with available experimental results. We also demonstrate two simple and accurate approaches for calculating the valence band offsets that are required for computing formation energies of charged defects, one based on a potential averaging scheme and the other using maximally-localized Wannier functions (MLWFs). Finally, we show that MLWFs provide a clear description of the nature of the electronic bonding at the defect centre that verifies the canonical Watkins model.

In this paper, we show that this success can be extended to other tasks of conditional audio generation. In particular, building upon HiFi vocoders, we propose a novel HiFi++ general framework for bandwidth extension and speech enhancement. We show that with the improved generator architecture, HiFi++ performs better or comparably with the state-of-the-art in these tasks while spending significantly less computational resources. The effectiveness of our approach is validated through a series of extensive experiments.

description: We present a parallel algorithm for the fast Fourier transform (FFT) in higher dimensions. This algorithm generalizes the cyclic-to-cyclic one-dimensional parallel algorithm to a cyclic-to-cyclic multidimensional parallel algorithm while retaining the property of needing only a single all-to-all communication step. This is under the constraint that we use at most $\sqrt{N}$ processors for an FFT on an array with a total of $N$ elements, irrespective of the dimension $d$ or the shape of the array. The only assumption we make is that $N$ is sufficiently composite. Our algorithm starts and ends in the same data distribution.
 We present our multidimensional implementation FFTU which utilizes the sequential FFTW program for its local FFTs, and which can handle any dimension $d$. We obtain experimental results for $d\leq 5$ using MPI on up to 4096 cores of the supercomputer Snellius, comparing FFTU with the parallel FFTW program and with PFFT and heFFTe. These results show that FFTU is competitive with the state of the art and that it allows one to use a larger number of processors, while keeping communication limited to a single all-to-all operation. For arrays of size $1024^3$ and $64^5$, FFTU achieves a speedup of a factor 149 and 176, respectively, on 4096 processors.

Single factor comparison of wireless coverage prediction maps

Publisher: name: University of British Columbia

description: Wireless system designers use wireless coverage prediction tools to assess the coverage that can be achieved (and the potential interference that may result) when transmitters or base stations are placed at various sites throughout a region. Current methods for assessing wireless coverage prediction accuracy tend to be ad hoc, have limited statistical power, and offer only limited insight concerning the quality of the results. Comparing coverage predictions to field measurement data would at first seem to be the best option for evaluating prediction accuracy. However, measurement data tends to be both sparse and expensive, while delivering few insights concerning the causes of prediction errors. Further, commercial wireless system planning tools generally incorporate at least rudimentary techniques for comparing predictions to measured data, but do not generally offer options for comparing predictions made using different models to each other. This is surprising given that the majority of such tools give users the option of using alternative prediction models. Prediction accuracy depends in equal measure upon the sophistication of the technique used to predict coverage and the quality of the geospatial data that describes both the natural and man-made obstacles and structures in the region. Here, we propose that single-factor comparison of prediction maps obtained using the same prediction technique but different geospatial data, or the same geospatial data but different prediction techniques, can help designers determine whether the prediction technique or the geospatial data is the limiting factor, and take appropriate action. In order to demonstrate the feasibility of this approach, we predicted the wireless coverage provided by 28 GHz base stations mounted on traffic signal arms at two different intersections on the University of British Columbia campus using two different wireless coverage prediction models but the same geospatial data. We then investigated the relative power of spatial autocorrelation, spatial cross-correlation, difference maps, and scatter plots to provide insights into similarities and differences between the prediction maps. The results demonstrate the feasibility of this approach and prepare the way for further study and development of single-factor comparison of wireless coverage prediction maps.

description: Let X be a smooth, connected, dimension n, quasi-projective variety imbedded in \PP_N. Consider integers {k_1,...,k_r}, with k_i>0, and the Hilbert Scheme H_{k_1,...,k_r}(X) of aligned, finite, degree \sum k_i, subschemes of X, with multiplicities k_i at points x_i (possibly coinciding). The expected dimension of H_{k_1,...,k_r}(X) is 2N-2+r-(\sum k_i)(N-n). We study the locus of points where H_{k_1,...,k_r}(X) is not smooth of expected dimension and we prove that the lines carrying this locus do not fill up \PP_N

description: In line with the recent development in topological graph theory, we are considering undirected graphs that are allowed to contain {\em multiple edges}, {\em loops}, and {\em semi-edges}. A graph is called {\em simple} if it contains no semi-edges, no loops, and no multiple edges. A graph covering projection, also known as a locally bijective homomorphism, is a mapping between vertices and edges of two graphs which preserves incidences and which is a local bijection on the edge-neighborhood of every vertex. This notion stems from topological graph theory, but has also found applications in combinatorics and theoretical computer science.
 It has been known that for every fixed simple regular graph $H$ of valency greater than 2, deciding if an input graph covers $H$ is NP-complete. Graphs with semi-edges have been considered in this context only recently and only partial results on the complexity of covering such graphs are known so far. In this paper we consider the list version of the problem, called \textsc{List-$H$-Cover}, where the vertices and edges of the input graph come with lists of admissible targets. Our main result reads that the \textsc{List-$H$-Cover} problem is NP-complete for every regular graph $H$ of valency greater than 2 which contains at least one semi-simple vertex (i.e., a vertex which is incident with no loops, with no multiple edges and with at most one semi-edge). Using this result we show the NP-co/polytime dichotomy for the computational complexity of \textsc{ List-$H$-Cover} for cubic graphs.

description: We show that near an armchair edge of a wide graphene channel, and in the presence of a smooth step-like electrostatic lateral confining potential, the chirality, spectrum, spatial structure, and number of the fundamental edge magnetoplasmons (EMPs), in the $ν=2$ regime of the quantum Hall effect, depend strongly on the position of the Fermi level $E_{F}$. (i) When $E_{F}$ is small enough and intersects four degenerate states of the zero Landau level (LL) at one location and two degenerate states of this level at a different one, two fundamental, counter propagating EMPs exist with opposite chirality. This is in contrast with EMPs in conventional two-dimensional electron systems in which only one fundamental EMP exists. For the same wave vector these EMPs have different moduli of phase velocities and an essential spatial overlap. These EMPs can be on resonance in a wide range of frequencies, for micron or submicron lengths along the edge. (ii) When $E_{F}$ is sufficiently high and intersects only two degenerate states of the zero LL only one fundamental EMP exists with the usual chirality.

description: Using a cosmological black hole model proposed recently, we have calculated the quasi-local mass of a collapsing structure within a cosmological setting due to different definitions put forward in the last decades to see how similar or different they are. It has been shown that the mass within the horizon follows the familiar Brown-York behavior. It increases, however, outside the horizon again after a short decrease, in contrast to the Schwarzschild case. Further away, near the void, outside the collapsed region, and where the density reaches the background minimum, all the mass definitions roughly coincide. They differ, however, substantially far from it. Generically, we are faced with three different Brown-York mass maxima: near the horizon, around the void between the overdensity region and the background, and another at cosmological distances corresponding to the cosmological horizon. While the latter two maxima are always present, the horizon mass maxima is absent before the onset of the central singularity.

Rooted America: Immobility and Segregation of the Intercounty Migration Network

description: Despite the popular narrative that the United States is a "land of mobility," the country may have become a "rooted America" after a decades-long decline in migration rates. This article interrogates the lingering question about the social forces that limit migration, with an empirical focus on internal migration in the United States. We propose a systemic, network model of migration flows, combining demographic, economic, political, and geographic factors and network dependence structures that reflect the internal dynamics of migration systems. Using valued temporal exponential-family random graph models, we model the network of intercounty migration flows from 2011 to 2015. Our analysis reveals a pattern of segmented immobility, where fewer people migrate between counties with dissimilar political contexts, levels of urbanization, and racial compositions. Probing our model using "knockout experiments" suggests one would have observed approximately 4.6 million (27 percent) more intercounty migrants each year were the segmented immobility mechanisms inoperative. This article offers a systemic view of internal migration and reveals the social and political cleavages that underlie geographic immobility in the United States.
