description: Background: There remains a substantial between-hospital variation in thrombolysis use among patients in England and Wales who arrive at hospital within 4 hours of known stroke onset. Thrombolysis use (2016 to 2018) in patients arriving within 4 hours of known stroke onset ranged from 7% to 49% between hospitals. Method: An Extreme Gradient Boosting (XGBoost) machine learning model, coupled with a SHAP explainability model, were used to predict which patients would receive thrombolysis at each hospital. The model was based on 88,928 patients arriving within 4 hours at all 132 emergency stroke units in England and Wales, as recorded in the national stroke audit SSNAP. Main Outcome Measures: SHAP values, providing estimates of how patient characteristics and hospital identity influence the odds of receiving thrombolysis. Results: The model revealed that the odds of receiving thrombolysis reduced 20-fold over the first 100 minutes of arrival-to-scan time, varied 30-fold depending on stroke severity, reduced 3-fold with imprecise onset time, fell 5-fold with increasing pre-stroke disability, and varied 15 fold between hospitals. The hospital identification (hospital SHAP value) explained 58% of the variance in between-hospital thrombolysis use. Compared with hospitals with higher thrombolysis use, hospitals with lower use were particularly less likely to give thrombolysis to patients with milder strokes, prior disability, or patients with imprecise onset time. Conclusions: Using explainable machine learning, we have identified that the majority of the between-hospital variation in thrombolysis use in England and Wales may be explained by differences in hospital predisposition to use thrombolysis.

description: We study the dynamics of a one-dimensional spin-orbit coupled Schrodinger particle with two internal components moving in a random potential. We show that this model can be implemented by the interaction of cold atoms with external lasers and additional Zeeman and Stark shifts. By direct numerical simulations a crossover from an exponential Anderson-type localization to an anomalous power-law behavior of the intensity correlation is found when the spin-orbit coupling becomes large. The power-law behavior is connected to a Dyson singularity in the density of states emerging at zero energy when the system approaches the quasi-relativistic limit of the random mass Dirac model. We discuss conditions under which the crossover is observable in an experiment with ultracold atoms and construct explicitly the zero-energy state, thus proving its existence under proper conditions.

On Close Relationship between Classical Time-Dependent Harmonic Oscillator and Non-Relativistic Quantum Mechanics in One Dimension

description: In this paper, I present a mapping between representation of some quantum phenomena in one dimension and behavior of a classical time-dependent harmonic oscillator. For the first time, it is demonstrated that quantum tunneling can be described in terms of classical physics without invoking violations of the energy conservation law at any time instance. A formula is presented that generates a wide class of potential barrier shapes with the desirable reflection (transmission) coefficient and transmission phase shift along with the corresponding exact solutions of the time-independent Schrödinger's equation. These results, with support from numerical simulations, strongly suggest that two uncoupled classical harmonic oscillators, which initially have a 90\degree relative phase shift and then are simultaneously disturbed by the same parametric perturbation of a finite duration, manifest behavior which can be mapped to that of a single quantum particle, with classical 'range relations' analogous to the uncertainty relations of quantum physics.

The use of surfactants to aid and improve the leaching of low grade copper ores
Creators: name: Shah, Kush
Publisher: name: University of British Columbia
Year: 2017

description: Copper heap leach operations often suffer from reduced efficiency due to long leach times and variable recoveries. Surfactants have been considered as an option in increasing the leachability of ores. Improvements in overall copper extraction have been noted with their use, though testing has only been conducted on a limited scale. The molecular function of surfactants in heap leaching has not been extensively studied and is not well explored. The work in this thesis was aimed at better understanding and characterizing the function of the surfactants. Work was performed with surfactants developed by BASF specifically for heap leaching. Initial experimentation consisted of using flooded vats to compare copper extraction from ores. Leach solution with and without surfactant was fed to the ores. The presence of surfactants was noted to increase the overall copper recovered by approximately 2-3%. Interfacial tension measurements were performed to determine the changes imparted onto the acidic leach solution by the surfactants. Hanging drops were used to determine the activity at the air-liquid boundary. It was found that at the surfactant concentrations used in heap leaching, the interfacial tension of the fluid changed very little, from about 71 mN/m to 69.5 mN/m. The contact angle was determined to better understand the interaction between the acidic media and the ore. This was obtained using capillary wicking and Washburn’s equation. Ore was finely ground and packed into particle beds. Leach liquid with surfactant was introduced to these beds. The rate of permeating fluid flow was monitored against time. The affinity of the liquid for the solid surface dictated the rate of uptake. Washburn’s equation allowed for the contact angle to be calculated from these results. It was found that surfactants lowered the contact angle of liquid on solid by up to 3 degrees. The combination of results indicated that the surfactants increases the affinity between the solid and liquid by reducing the contact angle. In a heap, this allows acid to ingress further into sub-surface regions of ore particles. As a result, leachability of the ore is increased as harder to reach minerals can be accessed.
Direct Policy Search for Adaptive Management of Flood Risk

Subjects: Industrial engineering

description: Direct policy search (DPS) has been shown to be an efficient method for identifying optimal rules (i.e., policies) for adapting a system in response to changing conditions. This dissertation describes three major advances in the usage of DPS for long-range infrastructure planning, using a specific application domain of flood risk management. We first introduce a new adaptive way to incorporate learning into DPS. The standard approach identifies policies by optimizing their average performance over a large ensemble of future states of the world (SOW). Our approach exploits information gained over time, regarding what kind of SOW is being experienced, to further improve performance via adaptive meta-policies defining how control of the system should switch between policies identified by a standard DPS approach (but trained on different SOWs). We outline the general method and illustrate it using a case study of optimal dike heightening extending the work of Garner and Keller (2018). The meta-policies identified by the adaptive algorithm show Pareto-dominance in two objectives over the standard DPS, with an overall 68% improvement in hypervolume. We also see the improved performance over three grouped SOWs based on future extreme water levels, with the hypervolume improvements of 90%, 46%, and 35% for low, medium, and high water level SOWs respectively. Additionally, we evaluate the degree of improvement achieved by different ways of implementing the algorithm (i.e., different hyperparameter values). This provides guidance for decision makers with different degrees of risk aversion, and computational budgets. Due to simplifying assumptions and limitations of the adaptive DPS model used in the chapter, such as uniform levee design heights, the Surge and Waves Model for Protection Systems (SWaMPS) is presented as a more realistic application of the DPS framework. SWaMPS is a process-based model of surge-based flood risk. This chapter marks the first implementation of DPS using a realistic process-based risk model. The physical process of storm surge and rainfall is simulated independently over multiple reaches, and different frequencies are explored to manage the production system in SWaMPS. The performance of the DPS algorithm is evaluated versus a static intertemporal optimization. The computational burden of evaluating the large ensemble of SOWs to include possible future events in DPS motivates us to apply scenario reduction methods to select representative scenarios that more efficiently span an uncertain parameter space. This allows us to reduce the runtime of the optimization process. We explore a range of data-mining tools, including principal component analysis (PCA) and clustering to reduce the scenarios. We compare the computational efficiency and quality of policies to this optimization problem with reduced ensembles of SOWs.

description: We generalise Jensen's result on the incompatibility of subcompactness with square. We show that alpha^+-subcompactness of some cardinal less than or equal to alpha precludes square_alpha, but also that square may be forced to hold everywhere where this obstruction is not present. The forcing also preserves other strong large cardinals. Similar results are also given for stationary reflection, with a corresponding strengthening of the large cardinal assumption involved. Finally, we refine the analysis by considering Schimmerling's hierarchy of weak squares, showing which cases are precluded by alpha^+-subcompactness, and again we demonstrate the optimality of our results by forcing the strongest possible squares under these restrictions to hold.

description: This research investigates the relationship between public participation and cultural heritage protection in small cities in China, with a focus on exploring the potential of integrating economic theory into cultural heritage preservation. The study is motivated by the global importance of cultural heritage, the diverse perspectives on heritage preservation, and the significance of public
involvement in safeguarding heritage. The research aims to address the challenges and complexities associated with cultural heritage preservation and examine the applicability of the "triple bottom line" theory in economics to sociology.
The research objectives are to identify the main problems of public participation in cultural heritage protection in China, understand the relationship between practice and theory in cultural heritage preservation, and explore the potential of economic theory in serving sociology. The research methodology involves a combination of qualitative and comparative analysis approaches, including literature review, comparative analysis, case studies, interviews, surveys, and data analysis. The findings from the research contribute to knowledge by exploring social constructivism and the integration of economic theory into cultural heritage preservation. The study provides insights into the main problems of public participation in cultural heritage protection in China under current political, economic, and social conditions. Additionally, it examines the relationship between public participation and local urban development through the lens of social constructivism. Furthermore, the research explores the potential of
applying the "triple bottom line" theory in economics to serve sociology, particularly in the context of cultural heritage preservation.
By addressing these research questions, the study offers recommendations and insights for effective cultural heritage preservation strategies, public participation frameworks, and the application of sustainable development principles. The findings can inform policymakers, practitioners, and
stakeholders involved in heritage preservation, contributing to the development of sustainable and inclusive models of cultural heritage protection in small cities in China. Overall, this research aims to contribute to the existing body of knowledge on cultural heritage preservation and promote the sustainable safeguarding of cultural heritage for future generations.
The hadronic light by light contribution to the $(g-2)_μ$ with holographic models of QCD

description: We study the anomalous electromagnetic pion form factor $F_{π^0γ^*γ^*}$ with a set of holographic models. By comparing with the measured value of the linear slope, some of these models can be ruled out. From the remaining models we obtain predictions for the low-energy quadratic slope parameters of $F_{π^0γ^*γ^*}$, currently out of experimental reach but testable in the near future. We find it particularly useful to encode this low-energy information in a form factor able to satisfy also QCD short-distance constraints. We choose the form factor introduced by D'Ambrosio, Isidori and Portoles in kaon decays, which has the right short distance for a particular value of the quadratic slope, which is later shown to be compatible with our holographic predictions. We then turn to a determination of the (dominant) pion exchange diagram in the hadronic light by light scattering contribution to the muon anomalous magnetic moment. We quantify the theoretical uncertainty in $(g-2)_μ$ coming from the different input we use: QCD short distances, experimental input and low-energy holographic predictions. We also test the pion-pole approximation. Our final result is $a_μ^{π^0}=6.54(25)\cdot 10^{-10}$, where the error is driven by the linear slope of $F_{π^0γ^*γ^*}$, soon to be measured with precision at KLOE-2. Our numerical analysis also indicates that large values of the magnetic susceptibility $χ_0$ are disfavored, therefore pointing at a mild effect from the pion off-shellness. However, in the absence of stronger bounds on $χ_0$, an additional $(10-15)%$ systematic uncertainty on the previous value for $a_μ^{π^0}$ cannot be excluded.

description: A sequence is nonrepetitive if it does not contain two adjacent identical blocks. The remarkable construction of Thue asserts that 3 symbols are enough to build an arbitrarily long nonrepetitive sequence. It is still not settled whether the following extension holds: for every sequence of 3-element sets $L_1,..., L_n$ there exists a nonrepetitive sequence $s_1, ..., s_n$ with $s_i\in L_i$. Applying the probabilistic method one can prove that this is true for sufficiently large sets $L_i$. We present an elementary proof that sets of size 4 suffice (confirming the best known bound). The argument is a simple counting with Catalan numbers involved. Our approach is inspired by a new algorithmic proof of the Lovász Local Lemma due to Moser and Tardos and its interpretations by Fortnow and Tao. The presented method has further applications to nonrepetitive games and nonrepetitive colorings of graphs.

These approximations are valid only in the semi-classical limit and the quantum capacitance in that case is determined by Lindhard function. The effective capacitance is the geometrical capacitance and the quantum capacitance in series, and this too is established starting from a microscopic theory.

description: A general formalism for joint weak measurements of a pair of complementary observables is given. The standard process of optical three-wave mixing in a nonlinear crystal (such as in parametric down-conversion) is suitable for such tasks. To obtain the weak value of a variable $A$ one performs weak measurements twice, with different initial states of the "meter" field. This seems to be a drawback, but as a compensation we get for free the weak value of a complementary variable $B$. The scheme is tunable and versatile: one has access to a continuous set of possible weak measurements of pair of observables. The scheme increases signal-to-noise ratio with respect to the case without postselection.

Adaptive wireless sensor network for real-time monitoring of water quality
Creators: name: Chen, Jiahong
Publisher: name: University of British Columbia
Year: 2017

description: Water quality problems have appeared in many places all around the world, and have caused severe public health problems. In identify the quality of different aquatic environments, wireless sensor networks have been used for monitoring large geographic areas of interest (AOI). Among the challenges of using wireless sensor networks for water quality monitoring in large areas, sensor node deployment strategy is a key consideration since an optimal sensor node deployment strategy can ensure the most appropriate utilization of the limited monitoring resources (sensor node, incorporated sensors, power supply, monitoring rates, etc.). To tackle such problems, we in the Industrial Automation Laboratory (IAL) of the Department of Mechanical Engineering, the University of British Columbia (UBC) have developed a mobile wireless sensor network for water quality monitoring. It has mobile (dynamic) sensor nodes, which can move to best sensing locations, and the ability to sense key water quality attributes. The developed platform is equipped with multiple nodes each of which having basic water quality detecting sensor probes, supports up to six propellers, and has upgradeable wireless communication boards. Besides, we have also proposed an optimal sensor node deployment strategy called “Rapid Random exploring tree with Linear Reduction” (RRLR) for this mobile wireless sensor network. The proposed method removes redundant sensor nodes depending on the linear dependence of sensor readings at the current deployment location without losing information. In this manner, spatial-temporal correlation of sensor node deployment in large geographic AOI can be minimized. The developed platform is demonstrated to have good performance even when moving against water flow and has low packet loss rate (0.85%) while transmitting data under different types of obstacles in real-world tests. Furthermore, the developed optimal sensor node deployment strategy, RRLR, requires nearly 60% fewer sensor nodes to achieve the same estimation error as our benchmark.
A review of naturalness and dark matter prediction for the Higgs mass in MSSM and beyond

Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Within a two-loop leading-log approximation, we review the prediction for the lightest Higgs mass (m_h) in the framework of constrained MSSM (CMSSM), derived from the naturalness requirement of minimal fine-tuning (Delta) of the electroweak scale and dark matter consistency. As a result, the Higgs mass is predicted to be just above the LEP2 bound, m_h=115.9\pm 2 GeV, corresponding to a minimal Delta=17.8, value obtained from consistency with electroweak and WMAP (3σ) constraints, but without the LEP2 bound. Due to quantum corrections (largely QCD ones for m_h above LEP2 bound), Delta grows \approx exponentially on either side of the above value of m_h, which stresses the relevance of this prediction. A value m_h>121 (126) GeV cannot be accommodated within the CMSSM unless one accepts a fine-tuning cost worse than Delta>100 (1000), respectively. We review how the above prediction for m_h and Delta changes under the addition of new physics beyond the MSSM Higgs sector, parametrized by effective operators of dimensions d=5 and d=6. For d=5 operators, one can obtain values m_h\leq 130 GeV for Delta<10. The size of the supersymmetric correction that each individual operator of d=6 brings to the value of m_h for points with Delta<100, is found to be small, of few (<4) GeV for M=8 TeV, where M is the scale of new physics. This value decreases (increases) by approximately 1 GeV for a 1 TeV increase (decrease) of the scale M. The relation of these results to the Atlas/CMS supersymmetry exclusion limits is presented together with their impact for the CMSSM regions of lowest fine-tuning.

description: Cod liver which is extracted in significant amounts from fish during the process of gutting and harvesting by fishing vessels in the North Atlantic and Barents Sea is a very valuable raw material for producing ‘natural’ tinned foods that have not undergone any additional treatment and which do not have any additional ingredients, but its use is limited due to lipid instability in long-term storage in a frozen state. The authors advise that the production and use of pre-treated semi-finished products which are based on the use of cod liver is managed by means of a microwave-cooking process which results in a product that is more stable for frozen storage. Any semi-finished fish oil product that is extracted during microwave processing can also be used in food production. The variants that can be included in using these semi-finished products are discussed here when it comes to the technology that is involved in functional multicomponent products (such as natural and paste tinned foods with the addition of sauces, vegetables, mushrooms, meat, and fish protein isolate).

description: Multi-task learning (MTL) is a rapidly growing field in the world of autonomous vehicles, particularly in the area of computer vision. Autonomous vehicles are heavily reliant on computer vision technology for tasks such as object detection, object segmentation, and object tracking. The complexity of sensor data and the multiple tasks involved in autonomous driving can make it challenging to design effective systems. MTL addresses these challenges by training a single model to perform multiple tasks simultaneously, utilizing shared representations to learn common concepts between a group of related tasks, and improving data efficiency. In this thesis, we proposed a scalable MTL system for object detection that can be used to construct any MTL network with different scales and shapes. The proposed system is an extension to the state-of-art algorithm called Mask RCNN. It is designed to overcome the limitations of learning multiple objects in multi-label learning. To demonstrate the effectiveness of the proposed system, we built three different networks using it and evaluated their performance on the state-of-the-art BDD100k dataset. Our experimental results demonstrate that the proposed MTL networks outperform a base single-task network, Mask RCNN, in terms of mean average precision at 50 (mAP50). Specifically, the proposed MTL networks achieved a mAP50 of 66%, while the base network only achieved 53%. Furthermore, we also conducted comparisons between the proposed MTL networks to determine the most efficient way to group tasks together in order to create an optimal MTL network for object detection on the BDD100k dataset.

The field theoretic approach to the integral and fractional effect is sketched, with some emphasis on the mechanism of electromagnetic gauge anomaly cancellation by chiral degrees of freedom living on the edge of the sample. Applications of this formalism to the design and theoretical interpretation of interference experiments are outlined.

description: We explore the model-independent constraints from cosmology on a dark-matter particle with no prominent standard model interactions that interacts and thermalizes with other particles in a hidden sector. Without specifying detailed hidden-sector particle physics, we characterize the relevant physics by the annihilation cross section, mass, and temperature ratio of the hidden to visible sectors. While encompassing the standard cold WIMP scenario, we do not require the freeze-out process to be nonrelativistic. Rather, freeze-out may also occur when dark matter particles are semirelativistic or relativistic. We solve the Boltzmann equation to find the conditions that hidden-sector dark matter accounts for the observed dark-matter density, satisfies the Tremaine-Gunn bound on dark-matter phase space density, and has a free-streaming length consistent with cosmological constraints on the matter power spectrum. We show that for masses <1.5 keV no region of parameter space satisfies all these constraints. This is a gravitationally-mediated lower bound on the dark-matter mass for any model in which the primary component of dark matter once had efficient interactions -- even if it has never been in equilibrium with the standard model.

description: It is well known that a plane graph is Eulerian if and only if its geometric dual is bipartite. We extend this result to partial duals of plane graphs. We then characterize all bipartite partial duals of a plane graph in terms of oriented circuits in its medial graph.

FAST LEARNING ON GRAPHS

Publisher: name: Universit� degli Studi di Milano

description: We carry out a systematic study of classification problems on networked data, presenting novel techniques with good performance both in theory and in practice. We assess the power of node classification based on class-linkage information only. In particular, we propose four new algorithms that exploit the homiphilic bias (linked entities tend to belong to the same class) in different ways. The set of the algorithms we present covers diverse practical needs: some of them operate in an active transductive setting and others in an on-line transductive setting. A third group works within an explorative protocol, in which the vertices of an unknown graph are progressively revealed to the learner in an on-line fashion. Within the mistake bound learning model, for each of our algorithms we provide a rigorous theoretical analysis, together with an interpretation of the obtained performance bounds. We also design adversarial strategies achieving matching lower bounds. In particular, we prove optimality for all input graphs and for all fixed regularity values of suitable labeling complexity measures. We also analyze the computational requirements of our methods, showing that our algorithms can to handle very large data sets. In the case of the on-line protocol, for which we exhibit an optimal algorithm with constant amortized time per prediction, we validate our theoretical results carrying out experiments on real-world datasets.
Ultraviolet Complete Electroweak Model Without a Higgs Particle

description: An electroweak model with running coupling constants described by an energy dependent entire function is utraviolet complete and avoids unitarity violations for energies above 1 TeV. The action contains no physical scalar fields and no Higgs particle and the physical electroweak model fields are local and satisfy microcausality. The $W$ and $Z$ masses are compatible with a symmetry breaking $SU(2)_L\times U(1)_Y \rightarrow U(1)_{\rm em}$, which retains a massless photon. The vertex couplings possess an energy scale $Λ_W > 1$ TeV predicting scattering amplitudes that can be tested at the LHC.

Revealing the impact of sequence variants on transcription factor binding and gene expression
Creators: name: Shi, Wenqiang
Publisher: name: University of British Columbia

description: Transcription factors (TFs) can bind to specific regulatory regions to control the expression of target genes. Disruption of TF binding is regarded as one of the key mechanisms by which regulatory variants could act to cause disease. However predicting the functional impact of variants on TF binding remains a major challenge for the field, standing as a key obstacle to achieving the potential of clinical genome analysis. This thesis confronts this challenge from a bioinformatics perspective and addresses two unresolved problems. The first problem is the determination of which genetic variants alter TF binding. Only a small number of allele-specific binding (ASB) events, in which TFs preferentially bind to one of two alleles at heterozygous sites in the genome, have been determined. To study the impact of variants on TF binding, access to a large, gold standard collection of ASB events could facilitate the development of new predictive methods. In Chapter 2, we implemented a pipeline to identify ASB events from ChIP-seq data and applied it to produce one of the largest ASB datasets. We found that ASB events were associated with allelic alterations of TF motifs, chromatin accessibility and histone modifications. Using the available features, classifiers were trained to predict the impact of variants on TF binding. To improve ASB calling, Chapter 3 evaluated five statistical methods, ultimately supporting a method that pooled ChIP-seq replicates and utilized a binomial distribution to model allelic read counts. The second problem is to determine how altered TF binding events impact the expression of target genes. In Chapter 4, we implemented regression-based models to predict gene expression changes based on altered TF binding events across 358 individuals. The models showed predictive capacity for 19.2% of genes, and the key TF binding events in the model provided mechanistic insights as to how these regulatory variants alter gene expression. In summary, this thesis both generated the largest, high-quality collection of ASB events, and developed algorithms to predict variant impact on TF binding and gene expression. The presented work advances the capacity of the field to interpret regulatory variants and will facilitate future clinical genome analysis.
