description: This is number fifteen of 42 preservation briefs prepared by the Technical Preservation Services of the National Park Service. This brief focuses on problems and general approaches for the preservation of historic concrete. This Brief surveys the principal problems posed by concrete deterioration, their likely causes, and approaches to their remedies. In almost every instance, remedial work should only be undertaken by qualified professionals. Faulty concrete repair can worsen structural problems and lead to further damage or safety hazards. Concrete repairs are not the province of do-it-yourselfers. Consequently, the corrective measures discussed here are included for general information purposes only; they do not provide "how to" advice.

description: We define a notion of target space entanglement entropy. Rather than partitioning the base space on which the theory is defined, we consider partitions of the target space. This is the physical case of interest for first-quantized theories, such as worldsheet string theory. We associate to each subregion of the target space a suitably chosen sub-algebra of observables $\mathcal{A}$. The entanglement entropy is calculated as the entropy of the density matrix restricted to $\mathcal{A}$. As an example, we illustrate our framework by computing spatial entanglement in first-quantized many-body quantum mechanics. The algebra $\mathcal{A}$ is chosen to reproduce the entanglement entropy obtained by embedding the state in the fixed particle sub-sector of the second-quantized Hilbert space. We then generalize our construction to the quantum field-theoretical setting.
Turbulent Taylor-Couette Flow based on LDV Measurement — Investigation on the Flow Field
Creators: Wang, Yicong
Publisher: name: University of Alberta Library
Year: 2022

The flow structure in turbulent Taylor vortex flow (TTV) was investigated in Newtonian and shear-thinning fluids. The radius ratio of the investigated case is η=0.76, and the aspect ratio of the experimental setup is 10.32.

First, detailed velocity measurements of the time-averaged azimuthal and axial components were performed with a Newtonian fluid (glycerin-water mixture). Radial profiles were obtained at the midheight of the cylinder, and axial profiles were obtained at three different radial positions. In Re=1100~3200, all the results of the two velocity components showed the same periodicity in the axial profiles, indicating the ubiquitous existence of the Taylor vortex structure in TTV (Turbulent Taylor vortex flow). Radial jet flows resulted in the transport of angular momentum, and some differences in the vortex structure were also found by comparing TTV with TVF. The local Reynolds number was analyzed with the help of the radial profiles, and the rationality of an alternative definition of the Reynolds number was evaluated by considering the real local Reynolds number.

Similar measurements were performed for the aqueous solution of Xanthan gum, which is strongly shear thinning and weakly elastic, with two different concentrations. The results also revealed the Taylor vortex in the flow field in the investigated range. Unlike the Newtonian case, TTV with shear-thinning fluids exhibited different modes with ununified Taylor vortex wavelengths. For the case of low-concentration shear thinning, two distinctly different distributions were discovered in the radial profiles, which were directly resulted by the two opposite directions of the jet flow in different modes.

Adversarial Training for Improving the Robustness of Deep Neural Networks
Creators: Hou, Pengyue
Publisher: name: University of Alberta Library
Year: 2022

Since 2013, Deep Neural Networks (DNNs) have caught up to a human-level performance

at various benchmarks. Meanwhile, it is essential to ensure its safety and

reliability. Recently an avenue of study questions the robustness of deep learning models

and shows that adversarial samples with human-imperceptible noise can easily fool

DNNs. Since then, many strategies have been proposed to improve the robustness of

DNNs against such adversarial perturbations. Among many defense strategies, adversarial

training (AT) is one of the most recognized methods and constantly yields

state-of-the-art performance. It treats adversarial samples as augmented data and

uses them in model optimization.

Despite its promising results, AT has two problems to be improved: (1) poor

generalizability on adversarial data (e.g. large robustness performance gap between

training and testing data), and (2) a big drop in model’s standard performance. This

thesis tackles the above-mentioned drawbacks in AT and introduces two AT strategies.

To improve the generalizability of AT-trained models, the first part of the thesis introduces

a representation similarity-based AT strategy, namely self-paced adversarial

training (SPAT). We investigate the imbalanced semantic similarity among different

categories in natural images and discover that DNN models are easily fooled by adversarial

samples from their hard-class pairs. With this insight, we propose SPAT

to re-weight training samples adaptively during model optimization, enforcing AT to

focus on those data from their hard class pairs.

To address the second problem in AT, a big performance drop on clean data, the

second part of this thesis attempts to answer the question: to what extent the robustness of the model can be improved without sacrificing standard performance? Toward

this goal, we propose a simple yet effective transfer learning-based adversarial training

strategy that disentangles the negative effects of adversarial samples on model’s standard

performance. In addition, we introduce a training-friendly adversarial attack

algorithm, which boosts adversarial robustness without introducing significant training

complexity. Compared to prior arts, extensive experiments demonstrate that the

training strategy leads to a more robust model while preserving the model’s standard

accuracy on clean data.
Fermi Surface Instabilities in Ferromagnetic Superconductor URhGe

description: The field-reentrant (field-reinforced) superconductivity on ferromagnetic superconductors is one of the most interesting topics in unconventional superconductivity. The enhancement of effective mass and the induced ferromagnetic fluctuations play key roles for reentrant superconductivity. However, the associated change of the Fermi surface, which is often observed at (pseudo-) metamagnetic transition, can also be a key ingredient. In order to study the Fermi surface instability, we performed Hall effect measurements in the ferromagnetic superconductor URhGe. The Hall effect of URhGe is well explained by two contributions, namely by the normal Hall effect and by the large anomalous Hall effect due to skew scattering. The large change in the Hall coefficient is observed at low fields between the paramagnetic and ferromagnetic states for H // c-axis (easy-magnetization axis) in the orthorhombic structure, indicating that the Fermi surface is reconstructed in the ferromagnetic state below the Curie temperature (T_Curie=9.5K). At low temperatures (T << T_Curie), when the field is applied along the b-axis, the reentrant superconductivity was observed in both the Hall resistivity and the magnetoresistance below 0.4K. Above 0.4K, a large jump with the first-order nature was detected in the Hall resistivity at a spin-reorientation field H_R ~ 12.5T, demonstrating that the marked change of the Fermi surface occurs between the ferromagnetic state and the polarized state above H_R. The results can be understood by the Lifshitz-type transition, induced by the magnetic field or by the change of the effective magnetic field.

description: We report here a photoconductive material for THz generation and detection with sub-picosecond carrier lifetime made by C12 (Carbon) irradiation on commercially available semi-insulating (SI) GaAs. We are able to reduce the carrier lifetime of SI-GaAs down to sub-picosecond by irradiating it with various irradiation dosages of Carbon (C12) ions. With an increase of the irradiation dose from ~1012 /cm2 to ~1015 /cm2 the carrier lifetime of SI-GaAs monotonously decreases to 0.55 picosecond, resulting in strongly improved THz pulse detection compared with normal SI-GaAs.

description: The segmentation of neonatal brain MR image into white matter (WM), gray matter (GM), and cerebrospinal fluid (CSF), is challenging due to the low spatial resolution, severe partial volume effect, high image noise, and dynamic myelination and maturation processes. Atlas-based methods have been widely used for guiding neonatal brain segmentation. Existing brain atlases were generally constructed by equally averaging all the aligned template images from a population. However, such population-based atlases might not be representative of a testing subject in the regions with high inter-subject variability and thus often lead to a low capability in guiding segmentation in those regions. Recently, patch-based sparse representation techniques have been proposed to effectively select the most relevant elements from a large group of candidates, which can be used to generate a subject-specific representation with rich local anatomical details for guiding the segmentation. Accordingly, in this paper, we propose a novel patch-driven level set method for the segmentation of neonatal brain MR images by taking advantage of sparse representation techniques. Specifically, we first build a subject-specific atlas from a library of aligned, manually segmented images by using sparse representation in a patch-based fashion. Then, the spatial consistency in the probability maps from the subject-specific atlas is further enforced by considering the similarities of a patch with its neighboring patches. Finally, the probability maps are integrated into a coupled level set framework for more accurate segmentation. The proposed method has been extensively evaluated on 20 training subjects using leave-one-out cross validation, and also on 132 additional testing subjects. Our method achieved a high accuracy of 0.919±0.008 for white matter and 0.901±0.005 for gray matter, respectively, measured by Dice ratio for the overlap between the automated and manual segmentations in the cortical region.

description: We address the modulation instability of the Hirota equation in the presence of stochastic spatial incoherence and linear time-dependent amplification/attenuation processes via the Wigner function approach. We show that the modulation instability remains baseband type, though the damping mechanisms substantially reduce the unstable spectrum independent of the higher-order contributions (e.g. the higher-order nonlinear interaction and the third-order dispersion). Additionally, we find out that the unstable structure due to the Kerr interaction exhibits a significant resilience to the third-order-dispersion stabilizing effects in comparison with the higher-order nonlinearity, as well as a moderate Lorentzian spectrum damping may assist the rising of instability. Finally, we also discuss the relevance of our results in the context of current experiments exploring extreme wave events driven by the modulation instability (e.g. the generation of the so-called rogue waves).

description: The aim of this paper is to develop a spatial Gaussian predictive process (SGPP) framework for accurately predicting neuroimaging data by using a set of covariates of interest, such as age and diagnostic status, and an existing neuroimaging data set. To achieve better prediction, we not only delineate spatial association between neuroimaging data and covariates, but also explicitly model spatial dependence in neuroimaging data. The SGPP model uses a functional principal component model to capture medium-to-long-range (or global) spatial dependence, while SGPP uses a multivariate simultaneous autoregressive model to capture short-range (or local) spatial dependence as well as cross-correlations of different imaging modalities. We propose a three-stage estimation procedure to simultaneously estimate varying regression coefficients across voxels and the global and local spatial dependence structures. Furthermore, we develop a predictive method to use the spatial correlations as well as the cross-correlations by employing a cokriging technique, which can be useful for the imputation of missing imaging data. Simulation studies and real data analysis are used to evaluate the prediction accuracy of SGPP and show that SGPP significantly outperforms several competing methods, such as voxel-wise linear model, in prediction. Although we focus on the morphometric variation of lateral ventricle surfaces in a clinical study of neurodevelopment, it is expected that SGPP is applicable to other imaging modalities and features.

Combined gravitational and electromagnetic self-force on charged particles in electrovac spacetimes

description: We consider the self-force on a charged particle moving in a curved spacetime with a background electromagnetic field, extending previous studies to situations in which gravitational and electromagnetic perturbations are comparable. The formal expression $f^{ret}_α$ for the self-force on a particle, written in terms of the retarded perturbed fields, is divergent, and a renormalization is needed to find the particle's acceleration at linear order in its mass $m$ and charge $e$. We assume that, as in previous work in a Lorenz gauge, the renormalization for accelerated motion comprises an angle average and mass renormalization. Using the short distance expansion of the perturbed electromagnetic and gravitational fields, we show that the renormalization is equivalent to that obtained from a mode sum regularization in which one subtracts from the expression for the self-force in terms of the retarded fields a singular part field comprising only the leading and subleading terms in the mode sum. The most striking part of our result, arising from a remarkable cancellation, is that the renormalization involves no mixing of electromagnetic and gravitational fields. In particular, the renormalized mass is obtained by subtracting (1) the purely electromagnetic contribution from a point charge moving along an accelerated trajectory and (2) the purely gravitational contribution from a point mass moving along the same trajectory. In a mode-sum regularization, the same cancellation implies that the required regularization parameters are sums of their purely electromagnetic and gravitational values.

Technical and Design Optimizations of the Polymer Extrusion 3D Printing Process towards Circular Economy
Creators: Kuclourya, Tanay
Publisher: name: University of Alberta Library
Year: 2022

Plastics have emerged as one of the essential materials present on the planet. However, its accumulation can negatively impact the environment if not disposed of properly. To counter this issue, the ‘Circular Economy’ is one such economic growth model with one of the objectives of using plastic resources efficiently. Several plastic recycling methodologies have been derived, out of which Distributed Recycling via Additive Manufacturing (DRAM) is one of them. It is a closed-loop material reprocessing solution that promotes a circular economy. In this thesis, three main research objectives are targeted. The first objective is to form an optimal link between two different areas of knowledge domains: plastic recycling and additive manufacturing. With an aim to validate the theoretical models related to these two fields, a Scientometric analysis followed by a critical review has been conducted to measure the former knowledge domains of plastic recycling and additive manufacturing. The second research objective is yet another attempt to promote the concept of Circular economy as it tends to fill the literature gaps related to material properties and effect of recycling at different stages of the DRAM process through some experimentations. This thesis contributes to these research gaps by comparing the effect of reprocessing cycles (recycling) with the effect of FDM printing parameters such as Raster angle orientation, Infill density and Extrusion Temperature on the mechanical properties of the 3D printed material. By setting up Design of Experiments, these four parameters are ranked based on their impact on the tensile properties of PLA dog bone specimens. Additionally, a novel analysis on time and the number of specimens to be 3D printed at each reprocessing stage has also been conducted for assisting the future researchers in managing their printing schedule especially in the recycling domain.  Lastly, with a vision of utilizing Plastic Solid Wastes (PSW) in 3D printing and contributing to Circular Economy, the third and the final objective of this thesis is to design a novel 3D printing system which targets high throughput and expands the range of feedstock material. A successful attempt has been made in this direction by designing a hybrid high-throughput 3D printer which works on the FDM and Direct FDM technologies. The focus and scope of this thesis was to utilize this hybrid system to print both virgin as well as recycled PLA separately, with a future goal to use both the technologies simultaneously for printing multi-material structures and also to use non-conventional printing materials. In this work, after several trials of printing and setting up some printing parameters, the proposed system was able to print with virgin as well as recycled PLA.

Furthermore we introduce general classes of oscillatory integral operators with inhomogeneous phase functions, whose local and global regularity are also established in classical function spaces (both in the Banach and quasi-Banach scales). The results are then applied to obtain optimal (local in time) estimates for the solution to the Cauchy problem for variable-coefficient Schrödinger equations as well as other evolutionary partial differential equations.

description: Sulcal pits, the locally deepest points in sulci of the highly convoluted and variable cerebral cortex, are found to be spatially consistent across human adult individuals. It is suggested that sulcal pits are genetically controlled and have close relationships with functional areas. To date, the existing imaging studies of sulcal pits are mainly focused on adult brains, yet little is known about the spatial distribution and temporal development of sulcal pits in the first 2 years of life, which is the most dynamic and critical period of postnatal brain development. Studying sulcal pits during this period would greatly enrich our limited understandings of the origins and developmental trajectories of sulcal pits, and also provide important insights into many neurodevelopmental disorders associated with abnormal cortical foldings. In this paper, by using surface-based morphometry, for the first time, we systemically investigated the spatial distribution and temporal development of sulcal pits in major cortical sulci from 73 healthy infants, each with longitudinal 3T MR scans at term birth, 1 year, and 2 years of age. Our results suggest that the spatially consistent distributions of sulcal pits in major sulci across individuals have already existed at term birth and this spatial distribution pattern keeps relatively stable in the first 2 years of life, despite that the cerebral cortex expands dramatically and the sulcal depth increases considerably during this period. Specially, the depth of sulcal pits increases regionally heterogeneously, with more rapid growth in the high-order association cortex, including the prefrontal and temporal cortices, than the sensorimotor cortex in the first 2 years of life. Meanwhile, our results also suggest that there exist hemispheric asymmetries of the spatial distributions of sulcal pits in several cortical regions, such as the central, superior temporal and postcentral sulci, consistently from birth to 2 years of age, which likely has close relationship with the lateralization of brain functions of these regions. This study provides detailed insights into the spatial distribution and temporal development of deep sulcal landmarks in infants.

description: We examine the charge density wave (CDW) properties of 1$T$-VSe$_{2}$ crystals grown by chemical vapour transport (CVT) under varying conditions. Specifically, we find that by lowering the growth temperature ($T_{\mathrm{g}}$ $<$ 630$^{\circ}$C), there is a significant increase in both the CDW transition temperature and the residual resistance ratio (RRR) obtained from electrical transport measurements. Using x-ray photoelectron spectroscopy (XPS), we correlate the observed CDW properties with stoichiometry and the nature of defects. In addition, we have optimized a method to grow ultra-high purity 1$T$-VSe$_{2}$ crystals with a CDW transition temperature, $T_{\mathrm{CDW}}$ = (112.7 $\pm$ 0.8) K and maximum residual resistance ratio (RRR) $\approx$ 49, which is the highest reported thus far. This work highlights the sensitivity of the CDW in 1$T$-VSe$_{2}$ to defects and overall stoichiometry, and the importance of controlling the crystal growth conditions of strongly-correlated transition metal dichalcogenides.

Representation of finite graphs as difference graphs of S-units, I

Publisher: name: arXiv
Year: 2014
Subjects: subject: Combinatorics (math.CO)
subject: FOS: Mathematics

description: Let G be a simple finite graph such that each vertex has an integer value and different vertices have different values. Let S be a finite non-empty set of primes. We call G an S-graph if any two vertices are connected by an edge if and only their values differ by a number which is composed of primes from S. We prove e.g. that for every G there exist infinitely many finite sets S such that G is an S-graph. We deal with cycles and complete bipartite graphs G. We consider the triangles in G for a deeper analysis. Finally we prove that G is an S-graph for all S if and only if G is cubical. Besides combinatorial and numbertheoretical arguments some deep Diophantine results concerning S-unit equations are used in our proofs.
Adapting to the Future

description: This research examines the complex legal landscape surrounding duty of care, liability, and accountability in the context of Artificial Intelligence (AI) integration in healthcare. As AI systems become increasingly involved in medical practices and clinical decision-making, their unique characteristics, such as opaque "black box" decision-making and lack of human-like reasoning, pose significant challenges to existing legal frameworks. The study highlights the inadequacy of medical negligence laws in addressing AI-related incidents in healthcare and the potential of vicarious liability, product liability, the concept of the “reasonable computer”, and transparency regulations in addressing AI errors. The findings emphasise the importance of ongoing regulatory adaptation to ensure that legal frameworks evolve with advancements in AI technology, ultimately safeguarding the interests of patients and healthcare practitioners.

Regularity of Fourier integral operators with amplitudes in general Hörmander classes

description: We prove the global $L^p$-boundedness of Fourier integral operators that model the parametrices for hyperbolic partial differential equations, with amplitudes in classical Hörmander classes $S^{m}_{ρ, δ}(\mathbb{R}^n)$ for parameters $0<ρ\leq 1$, $0\leq δ<1$. We also consider the regularity of operators with amplitudes in the exotic class $S^{m}_{0, δ}(\mathbb{R}^n)$, $0\leq δ< 1$ and the forbidden class $S^{m}_{ρ, 1}(\mathbb{R}^n)$, $0\leqρ\leq 1.$ Furthermore we show that despite the failure of the $L^2$-boundedness of operators with amplitudes in the forbidden class $S^{0}_{1, 1}(\mathbb{R}^n)$, the operators in question are bounded on Sobolev spaces $H^s(\mathbb{R}^n)$ with $s>0.$ This result extends those of Y. Meyer and E. M. Stein to the setting of Fourier integral operators.

A single radio-emitting nucleus in the dual AGN candidate NGC 5515

description: The Seyfert galaxy NGC 5515 has double-peaked narrow-line emission in its optical spectrum, and it has been suggested that this could indicate that it has two active nuclei. We observed the source with high resolution Very Long Baseline Interferometry (VLBI) at two radio frequencies, reduced archival Very Large Array data, and re-analysed its optical spectrum. We detected a single, compact radio source at the position of NGC 5515, with no additional radio emission in its vicinity. The optical spectrum of the source shows that the blue and red components of the double-peaked lines have very similar characteristics. While we cannot rule out unambiguously that NGC 5515 harbours a dual AGN, the assumption of a single AGN provides a more plausible explanation for the radio observations and the optical spectrum.
