description: Dust produced during mining activities has a detrimental effect on both miners’ health and operations’ safety. There is no definitive treatment for coal miners’ pneumoconiosis (CWP), which is caused by prolonged inhalation of respirable dust. Elevated coal dust concentrations have also been shown to cause several disastrous explosions in the United States and worldwide, resulting in the death of miners and loss of operations. Flooded-bed dust scrubbers are used on all modern-day continuous miners. These devices cleanse the dust-laden air and assist in bringing fresh air towards the mining face. Scrubbers use a multi-layered fibrous screen to capture airborne particles. These systems direct the dust-laden air towards the fibrous screen mounted upstream of a water spray. These screens capture dust on the finely woven surface. Prolonged scrubber operations lead to dust accumulation, which can result in filter clogging. This increases the pressure-drop across the screen and causes a lowered airflow through the scrubber. Reduced capture efficiency of the scrubber may lead to an enhanced exposure of the miners nearby.

This thesis presents the design of three full-scale non-clogging, maintenance-free impingement type screens. The findings of Computational Fluid Dynamics (CFD) modeling, laboratory studies using coal, and rock (limestone) dust to determine cleaning efficiency are presented. In-mine tests were conducted to examine the performance of each screen using limestone dust as an aerosol. The newly designed impingement screens outperform the conventional fibrous screen at all airflows between 4,000 and 8,000; therefore, they may be a potential replacement for the fibrous screen.

description: The fundamental theory of nature may allow a large landscape of vacua. Even if the theory contains a unified gauge symmetry, the 22 flavor parameters of the Standard Model, including neutrino masses, may be largely determined by the statistics of this landscape, and not by any symmetry. Then the measured values of the flavor parameters do not lead to any fundamental symmetries, but are statistical accidents; their precise values do not provide any insights into the fundamental theory, rather the overall pattern of flavor reflects the underlying landscape. We investigate whether random selection from the statistics of a simple landscape can explain the broad patterns of quark, charged lepton, and neutrino masses and mixings. We propose Gaussian landscapes as simplified models of landscapes where Yukawa couplings result from overlap integrals of zero-mode wavefunctions in higher-dimensional supersymmetric gauge theories. In terms of just five free parameters, such landscapes can account for all gross features of flavor, including: the hierarchy of quark and charged lepton masses; small quark mixing angles, with 13 mixing less than 12 and 23 mixing; very light Majorana neutrino masses, with the solar to atmospheric neutrino mass ratio consistent with data; distributions for leptonic 12 and 23 mixings that are peaked at large values, while the distribution for 13 mixing is peaked at low values; and order unity CP violating phases in both the quark and lepton sectors. While the statistical distributions for flavor parameters are broad, the distributions are robust to changes in the geometry of the extra dimensions. Constraining the distributions by loose cuts about observed values leads to narrower distributions for neutrino measurements of 13 mixing, CP violation, and neutrinoless double beta decay.

description: We introduce the concept of impedance matching to axion dark matter by posing the question of why axion detection is difficult, even though there is enough power in each square meter of incident dark-matter flux to energize a LED light bulb. By quantifying backreaction on the axion field, we show that a small axion-photon coupling does not by itself prevent an order-unity fraction of the dark matter from being absorbed through optimal impedance match. We further show, in contrast, that the electromagnetic charges and the self-impedance of their coupling to photons provide the principal constraint on power absorption integrated across a search band. Using the equations of axion electrodynamics, we demonstrate stringent limitations on absorbed power in linear, time-invariant, passive receivers. Our results yield fundamental constraints, arising from the photon-electron interaction, on improving integrated power absorption beyond the cavity haloscope technique. The analysis also has significant practical implications, showing apparent tension with the sensitivity projections for a number of planned axion searches. We additionally provide a basis for more accurate signal power calculations and calibration models, especially for receivers using multi-wavelength open configurations such as dish antennas and dielectric haloscopes.

description: In many real-world applications, the characteristics of data change over time. This behavior is known as concept drift. Maintaining optimal algorithms and their hyperparameters in such applications becomes cumbersome, as models become outdated very quickly. Although the data often consists of one-dimensional streams (e.g. collected by activity logs, sensors and mobile devices), in a higher level the aggregated sources produce multiple streams. Machine learning, therefore, requires univariate and multivariate analysis of long term dependencies to create valuable insights. In this thesis, we assess hundreds of combinations of data characteristics and methods in sequential data. Particularly we use real-life anomalous instances in the network traffic domain and to increase complexity we combine it with synthesized drifting data. From our preliminary evaluation of conventional machine learning, meta-learning and deep learning methods and comparing their generalization performance in the presence of concept drift, the results show that deep learning outperforms all other tested methods. Although, one-dimensional Convolutional Neural Networks (1D-CNN) produced the highest performance in image classification, similar to other models, they are able to label if sliding windows are anomalous or not. However, in majority of real-life applications, it is crucial to find individual instances that resulted in an anomalous pattern. Therefore, we introduce a method to transform the representation of the data to tensors of two dimensional images, enabling modern deep learning methods to become directly applicable to sequential data. We propose Sequential Mask Convolutional Neural Network (SMCNN) pinpoints the location of anomalous patterns. SMCNN model transforms sequential data by means of a specialized filter that produces flexible shape forms and detects multiple types of outliers simultaneously. In addition, to solve the issue of high ratio of False Positive in the unsupervised Generative Adversarial Networks (GAN) in concept drifts, we introduce a method for finding optimal sliding windows that automatically removes normal repetitive patterns. We introduce DriftGAN architecture that discriminates between normal and anomalous patterns. Our SMCNN and DriftGAN methods significantly outperform prior endeavours and provide high generalization capabilities on a wide array of one-dimensional data characteristics with repetitive nature.

description: The article is devoted to the investigation of groups of diffeomorphisms and loops of manifolds over ultra-metric fields of zero and positive characteristics. Different types of topologies are considered on groups of loops and diffeomorphisms relative to which they are generalized Lie groups or topological groups. Among such topologies pairwise incomparable are found as well. Topological perfectness of the diffeomorphism group relative to certain topologies is studied. There are proved theorems about projective limit decompositions of these groups and their compactifications for compact manifolds. Moreover, an existence of one-parameter local subgroups of diffeomorphism groups is investigated.

description: Health care professionals are at higher risk for work-related stress, burnout and compassion fatigue than other professionals. One coping strategy that has attracted considerable attention is the practice of self-compassion. Self-compassion training is associated with psychological benefits such as decreased self-criticism and rumination and increased connectedness, mindfulness, and life satisfaction. (Smeets et al., 2014). While there is preliminary evidence that online self-compassion training is as effective as in-person training (Finlay-Jones et al., 2016), length and duration of online programs may affect adherence. Accordingly, this study assessed the feasibility of a short, 4-week online self-compassion program tailored for students in health care professions. Since this was an exploratory study, there was no control group. A convenience sample of 31 students who were registered in health care profession programs at the University of Ottawa and other Canadian universities were recruited. Key feasibility indicators included ease of recruitment, retention, completion of outcome measures, and acceptability of the program (adherence, satisfaction, ease of use). The study also obtained preliminary data on the effects of the intervention on levels of self-compassion, mindfulness, depression, anxiety and stress. Recruitment was easier than expected, with 31 participants enrolled in the study within a 2-month period. Of these, 21 started the self-compassion training. Adherence to the daily self-compassion meditations was poor, with only four participants meditating at least 50% of the expected number of days. Participants rated the self-compassion meditations as easy to follow and satisfaction ratings were acceptable for three of the four meditations. However, only two of the meditations were perceived to be relevant to healthcare professions. Intent-to-treat analyses revealed that the mindfulness facet Nonjudge and levels of stress improved from pre-to- post study. Separate analyses on program starters revealed that the mindfulness facets Describe, Nonjudge, and Act with Awareness, and levels of stress and anxiety improved. However, it is unlikely that these changes were attributed to the meditation practice given the poor rate of adherence. Overall, results suggest that this brief online self-compassion meditation training may not be feasible for healthcare trainees at this time without certain modifications to the program.

description: Measurements at low energies provide interesting indirect information about masses of particles that are (so far) too heavy to be produced directly. Motivated by recent progress in consistently and rigorously calculating electroweak precision observables and flavour related observables, we derive the preferred value for m_h in the Constrained Minimal Supersymmetric Standard Model (CMSSM), obtained from a fit taking into account electroweak precision data, flavour physics observables and the abundance of Cold Dark Matter. No restriction is imposed on m_h itself: the experimental bound from direct Higgs boson search at LEP is not included in the fit. A multi-parameter chi^2 is minimized with respect to the free parameters of the CMSSM, M_0, M_1/2, A_0, tan(beta). A statistical comparison with the Standard Model fit to the electroweak precision data is made. The preferred value for the lightest Higgs boson mass in the CMSSM is found to be m_h^CMSSM = 110+8-10(exp.)+-3(theo.) GeV/c^2, where the first uncertainty is experimental and the second uncertainty is theoretical. This value is in agreement with the limit from direct Higgs boson search at LEP.

description: Deep multi-view stereo (MVS) methods have been developed and extensively compared on simple datasets, where they now outperform classical approaches. In this paper, we ask whether the conclusions reached in controlled scenarios are still valid when working with Internet photo collections. We propose a methodology for evaluation and explore the influence of three aspects of deep MVS methods: network architecture, training data, and supervision. We make several key observations, which we extensively validate quantitatively and qualitatively, both for depth prediction and complete 3D reconstructions. First, complex unsupervised approaches cannot train on data in the wild. Our new approach makes it possible with three key elements: upsampling the output, softmin based aggregation and a single reconstruction loss. Second, supervised deep depthmap-based MVS methods are state-of-the art for reconstruction of few internet images. Finally, our evaluation provides very different results than usual ones. This shows that evaluation in uncontrolled scenarios is important for new architectures.

This approach, inspired in the Lie (super)algebra structure, is explicitly applied to the particular case of (graded) contractions of the orthogonal real algebra ${\mathfrak{so}}(N+1)$. In this way we show that "classical" contraction parameters which appear in the commutation relations of the contracted Lie algebras, become quantum deformation parameters, arising as entries of the resulting quantum $R$-matrices.

Controls of Lithium and Strontium Isotopes Spatial Variability Across the Yukon River Basin: Implications for Weathering in a Warming Basin

description: The Yukon River drains a large catchment underlain by a range of geological units characterized by diverse topography, environmental conditions, and land cover. The Yukon River catchment also displays a permafrost cover gradient and has active alpine glaciers in its headwaters. With ongoing warming, permafrost degradation, glaciers retreat, and land cover changes, the hydrochemistry of the Yukon River will likely change with risks for water quality and ecosystem sustainability. Here, we report elemental and isotopic data across the Yukon River to unravel the processes controlling the geochemistry of the dissolved load across the watershed and investigate the sensitivity of hydrochemistry to climate conditions. We analyze 102 samples from most major tributaries of the Yukon River for major and trace elements, strontium isotope ratio (⁸⁷Sr/⁸⁶Sr) and lithium isotope composition (δ⁷Li). Elemental and isotopic geochemistry displays strong spatial patterns that primarily correlate with lithological, topographic and climatic characteristics over the watershed. In the glacial and mountainous headwaters, we observe low Li/Na ratio and low δ⁷Li values (<15‰). We suggest that glaciated headwaters are characterized by a very high denudation rate and low secondary mineral formation rate explaining the low δ⁷Li values. In most of the permafrost-covered lowlands, we observe relatively constant Li/Na ratio and δ⁷Li values suggesting that weathering intensity is at a steady state. Conversely, in the non-permafrost-covered lowlands, we observe higher and more variable Li/Na ratio and δ⁷Li values suggesting increased weathering intensity when permafrost is absent. In the lowlands, glaciated or not, ⁸⁷Sr/⁸⁶Sr ratios remain within a tight range of values (0.709-0.715) and reflect the variable contribution of carbonate and silicate units throughout the basin. We found an interesting relationship between δ⁷Li values and ⁸⁷Sr/⁸⁶Sr ratios, suggesting a strong geology influence on weathering processes. When ⁸⁷Sr/⁸⁶Sr are low or very high, δ⁷Li values tend to be high (>25‰), whereas when ⁸⁷Sr/⁸⁶Sr are intermediate δ⁷Li values are low. We argue that the presence of igneous rock units within the catchment is an important control of weathering intensity as igneous rock units can contribute fresh primary minerals for weathering reactions. Weathering intensity is also strongly associated with temperature and permafrost cover across the Yukon River. As temperature increases and permafrost thaws, the weathering intensity increases, modifying the flux of elements to rivers. As the climate continues to warm in the future, the Yukon River hydrochemistry will continue to evolve, reflecting the increased contribution of soils and clays to river water chemistry.

description: We introduce and study a new model: 0-automatic queues. Roughly, 0-automatic queues are characterized by a special buffering mechanism evolving like a random walk on some infinite group or monoid. The salient result is that all stable 0-automatic queues have a product form stationary distribution and a Poisson output process. When considering the two simplest and extremal cases of 0-automatic queues, we recover the simple M/M/1 queue, and Gelenbe's G-queue with positive and negative customers.

The parameters of a compressed representation of a mixed quantum state are adapted dynamically according to the Lindblad master equation by employing a time-dependent variational principle. We illustrate our approach by solving the dissipative quantum Heisenberg model in one and two dimensions for up to 40 spins and by applying it to the simulation of confinement dynamics in the presence of dissipation.

description: We demonstrate that partner symmetries provide a lift of noninvariant solutions of three-dimensional Boyer-Finley equation to noninvariant solutions of four-dimensional hyperbolic complex Monge-Ampere equation. The lift is applied to noninvariant solutions of the Boyer-Finley equation, obtained earlier by the method of group foliation, to yield noninvariant solutions of the hyperbolic complex Monge-Ampere equation. Using these solutions we construct new Ricci-flat ultra-hyperbolic metrics with non-zero curvature tensor that have no Killing vectors.

Revisiting the effect of nearby supernova remnants on local cosmic rays
Creators: name: Thoudam, Satyendra
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: In an earlier paper, the effect of the nearby known supernova remnants (SNRs) on the local cosmic-rays (CRs) was studied, considering different possible forms of the particle injection time. The present work is a continuation of the previous work, but assumes a more realistic model of CR propagation in the Galaxy. The previous work assumed an unbounded three-dimensional diffusion region, whereas the present one considers a flat cylindrical disc bounded in both the radial and vertical directions. The study has found that the effect of the vertical halo boundary $H$ on the local SNR contribution to the observed CR anisotropy is negligible as long as $H\gtrsim 2kpc$. Considering the values of the halo height $H\gtrsim 2kpc$ obtained by different authors, the present work suggests that the study of the effect of local sources on the CR anisotropy can be carried out without having much information on $H$ and hence, using the much simpler three-dimentional unbounded solution. Finally, the present work discusses about the possibility of explaining the observed anisotropy below the knee by a single dominant source with properly chosen source parameters, and claims that the source may be an \textit{undetected} old SNR with a characteristic age of $\sim 1.5\times 10^5 yr$ located at a distance of $\sim 0.57 kpc$ from the Sun.

Essays on financial asset pricing
Creators: name: Smith, Maxwell R.
Publisher: name: University of British Columbia
Year: 2010

description: The first essay of this thesis is concerned with the pricing of financial assets in positive net supply in a financial market with continuous time trading. A general equilibrium, continuous time model of an economy with production is developed. The model is used to develop a nonlinear partial differential equation whose solution gives the market price of the economy's aggregate long term physical/financial assets in terms of the consumption good. Partial differential equations that are linear are then developed for pricing individual physical/financial asset using the solution for the economy's aggregate of physical/financial assets. A particular solution is presented and applications to the pricing of bonds and the pricing of warrants and stock are made. Unlike previous models, financial assets represent a significant portion of the economy's wealth in this model. The model is generalized to include two kinds of production: risky instantaneous production of the consumption good and riskless production of long term physical/financial assets whose output is risky. The second essay develops the concept of market risk, which arises from the uncertainty investors have about the economy and the financial markets they trade in. A simple three date model with log and risk neutral investors trading a stock and bond is considered first. Market risk is modeled by introducing economy states which represent the possible economies that traders could be trading in. Two possible equilibria are shown to exist in the model: a separating equilibrium in which market prices reveal the economy state associated with the magnitude of the aggregate endowments of investors and a pooling equilibrium in which first period prices do not reveal the economy state. The concept of market risk, is used to develop a model of market crashes. Market crashes are modeled as pooling equilibria where the market price initially does not reveal the fundamental value of a financial asset and may not do so until the last trading opportunity takes place. The market price represents an average of possible final market prices. When the market price moves down sharply from a pooling price to a separating price that reveals the economy state the market crash takes place. The market crash occurs when a pooling price that does not reveal the economy state is no longer an equilibrium for the prevailing underlying economy state. Then the price must change and the economy state is revealed. Two methods of triggering the market crash are considered, one based upon information arriving to the market, the other based upon the arrival of new investors.

description: We revisit monochromatic and isotropic photon emissions from the zero-angular\linebreak-momentum sources (ZAMSs) near a Kerr black hole. We investigate the escape probability of the photons that can reach to infinity and study the energy shifts of these escaping photons, which could be expressed as the functions of the source radius and the black hole spin. We study the cases for generic source radius and black hole spin, but we pay special attention to the near-horizon (near-)extremal Kerr ((near-)NHEK) cases. We reproduce the relevant numerical results using a more efficient method and get new analytical results for (near-)extremal cases. The main non-trivial results are: in the NHEK region of a (near-)extremal Kerr black hole, the escape probability for a ZAMS tends to $\frac{7}{24}\approx 29.17\%$, independent of the NHEK radius; at the innermost of the photon shell (IPS) in the near-NHEK region, the escape probability for a ZAMS tends to \begin{equation} \frac{5}{12} -\frac{1}{\sqrt{7}} + \frac{2}{\sqrt{7}π}\arctan\frac{1}{\sqrt{7}}\approx12.57\% . \nonumber \end{equation} The results show that the photon escape probability remains a relatively large nonzero value even though the ZAMS is in the deepest region of a near-horizon throat of a high spin Kerr black hole, as long as the ZAMS is outside the IPS. The energies of the escaping photons at infinity, however, are all redshifted but still visible in principle.

description: Context. RR Gem is one of the few Blazhko RR Lyrae that has photometric observations available extended enough to study the long-term courses of its pulsation and modulation properties in detail. Aims. We investigate the pulsation and modulation properties and the relations between them in RR Gem using photometric observations from the past 70 years in order to gain further insight into the nature of the Blazhko modulation. Methods. We studied the photographic, photoelectric, and CCD light curves obtained at the Konkoly Observatory and other authors' published maxima observations. Detailed analysis of the light curves, maximum brightness, and O-C data are carried out. Results. RR Gem showed modulation most of the time it was observed. The modulation amplitude showed strong variations from the undetectable level (less than 0.04 mag in maximum brightness) to about 0.20 mag. The amplitudes of the amplitude and phase modulations showed parallel changes, thus the total 'power' of the modulation have changed during the past 70 years. Parallel changes in the pulsation and modulation periods occur with a d P_mod / d P_puls = 1.6 +/- 0.8 * 10^3 ratio. We also detected 0.05-0.1 mag changes in the mean maximum brightness and mean pulsation amplitude.

We show that the weighted number of zeros of Wronskians of certain solutions equals the value of Krein's spectral shift function inside essential spectral gaps.

title: Interactions among models of amyotrophic lateral sclerosis and Parkinson disease in Drosophila melanogaster
Creators: name: Hurley, Emily Priscilla
Publisher: name: Memorial University of Newfoundland

description: Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease characterized by the progressive loss of upper and lower motor neurons. In contrast, Parkinson Disease (PD) is a neurodegenerative disease characterized by the loss of dopaminergic neurons within the substantia nigra region of the brain. Recently, a number of genes have been identified to be involved in the progression of these diseases, this study focuses upon four ALS-related genes: TARDBP(TBPH), p62/SQSTM1(Ref(2)P), TBK1(IK2), and VCP(TER94). These genes have been linked to the autophagy pathway and its sub-type, mitophagy, which have been suggested to play substantial roles in the progression of ALS and PD. Employing the Drosophila model organism, I have investigated the consequences of the altered expression of these ALS-related genes in combination with modified PD gene activities in an attempt to discover potential interactions and similarities between the biological basis of neurodegenerative diseases and aging. Notable observations show that the inhibition of TBPH in the motor neurons leads to a reduction in longevity and locomotor ability, and, in complementary experiments, inhibition of TBPH in the developing neuron-rich Drosophila eye reduces the ommatidia and interommatidial bristle counts. The overexpression of IK2 in the motor neurons reduces longevity and locomotor ability. The inhibition of Ref(2)P in the motor neurons, as well as in the dopaminergic neurons, increases median lifespan, slightly, while severely reducing locomotor ability, which may suggest a compensational relationship between longevity and motor function. The inhibition of Ref(2)P and parkin in the ddc-Gal4-expressing neurons provided an increase in lifespan, while resulting in a reduction in locomotor ability. Investigation of the inhibition of TER94 provided variable results, however I have shown that inhibition of TER94 in the dopaminergic neurons can reduce longevity and locomotor ability over time. The co-inhibition of TER94 and parkin has shown a marked reduction in lifespan (by ~30%) and a reduction in locomotor ability. In contrast, the inhibition of TER94 in combination with the expression of alpha-synuclein has shown an large increase in lifespan (by ~28%), with an accompanying reduction in locomotor ability over time. Investigation of these candidate genes and their role in a model of human disease progression has provided some clues to our understanding of ALS and PD.

Unification of twistors and Ramond vectors

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We generalize the idea of supertwistors and introduce a new supersymmetric object - the $θ$-twistor which includes the composite Ramond vector [11] well known from the spinning string dynamics. The symmetries of the chiral $θ$-twistor superspace are studied. It is shown that the chiral spin structure introduced by the $θ$-twistor breaks the superconformal boost symmetry but preserves the scale symmetry and the super-Poincare symmetry. This geometrical effect of breaking correlates with the Gross-Wess effect of the conformal boost breaking for bosonic scattering amplitudes.

Production of Higgs boson excitations of universal extra dimension at the Large Hadron Collider

description: The Kaluza-Klein excitations of the Higgs bosons of the universal extra dimension model are extremely challenging to detect. We discuss the production and possible detection mechanisms of such excited scalars at the LHC. The dominant production mechanism of such scalars is from the decay of the excited third generation quarks. In particular, the charged Higgs boson has a large production cross-section over most of the parameter space. We highlight how one may detect these excited scalars. We also comment on the production and detection of excited neutral scalars.

description: The stability conditions of a relativistic hydrodynamic theory can be derived directly from the requirement that the entropy should be maximised in equilibrium. Here we use a simple geometrical argument to prove that, if the hydrodynamic theory is stable according to this entropic criterion, then localised perturbations to the equilibrium state cannot propagate outside their future light-cone. In other words, within relativistic hydrodynamics, acausal theories must be thermodynamically unstable, at least close to equilibrium. We show that the physical origin of this deep connection between stability and causality lies in the relationship between entropy and information. Our result may be interpreted as an ``equilibrium conservation theorem'', which generalizes the Hawking-Ellis vacuum conservation theorem to finite temperature and chemical potential.
