A Compound Gaussian Least Squares Algorithm and Unrolled Network for Linear Inverse Problems

description: For solving linear inverse problems, particularly of the type that appears in tomographic imaging and compressive sensing, this paper develops two new approaches. The first approach is an iterative algorithm that minimizes a regularized least squares objective function where the regularization is based on a compound Gaussian prior distribution. The compound Gaussian prior subsumes many of the commonly used priors in image reconstruction, including those of sparsity-based approaches. The developed iterative algorithm gives rise to the paper's second new approach, which is a deep neural network that corresponds to an "unrolling" or "unfolding" of the iterative algorithm. Unrolled deep neural networks have interpretable layers and outperform standard deep learning methods. This paper includes a detailed computational theory that provides insight into the construction and performance of both algorithms. The conclusion is that both algorithms outperform other state-of-the-art approaches to tomographic image formation and compressive sensing, especially in the difficult regime of low training.

description: We study the families of nonlinear modes described by the nonlinear Schrödinger equation with the PT-symmetric harmonic potential $x^2-2iαx$. The found nonlinear modes display a number of interesting features. In particular, we have observed that the modes, bifurcating from the different eigenstates of the underlying linear problem, can actually belong to the same family of nonlinear modes. We also show that by proper adjustment of the coefficient $α$ it is possible to enhance stability of small-amplitude and strongly nonlinear modes comparing to the well-studied case of the real harmonic potential.

Symmetric mixed states of $n$ qubits: local unitary stabilizers and entanglement classes
Creators: name: Lyons, David W.

description: We classify, up to local unitary equivalence, local unitary stabilizer Lie algebras for symmetric mixed states into six classes. These include the stabilizer types of the Werner states, the GHZ state and its generalizations, and Dicke states. For all but the zero algebra, we classify entanglement types (local unitary equivalence classes) of symmetric mixed states that have those stabilizers. We make use of the identification of symmetric density matrices with polynomials in three variables with real coefficients and apply the representation theory of SO(3) on this space of polynomials.

Homeostasis of myeloid cells in the CNS and their roles in neuroinflammatory disease
Creators: name: Ajami, Bahareh
Publisher: name: University of British Columbia
Year: 2011

description: A key regulator of central nervous system (CNS) inflammatory responses is a highly specialized subset of tissue macrophages that reside in the CNS parenchymal and perivascular spaces known as “microglia”. Microgliosis is a common response to multiple types of damage within the CNS and is commonly characterized by an increase in microglial cells. What remains elusive, however, is the origin of cells involved in this phenomenon and whether the increase in the number of cells is due to local expansion or recruitment of myeloid progenitors from the bloodstream. Here, we investigated the origin of microglia using chimeric animals obtained by parabiosis. We found no evidence of circulating myeloid cells recruitment under healthy conditions and in denervation or CNS neurodegenerative disease suggesting that microglia can respond to CNS trauma and degeneration by expanding in situ independently of the contribution of blood-derived myeloid precursors. Furthermore, I investigated the extent to which blood-derived myeloid cells contribute to the microglia population in conditions where other circulating blood-borne cells have access to the CNS, such as in multiple sclerosis, an autoimmune disease of CNS and its murine model experimental autoimmune encephalitis (EAE). Using a novel approach to specifically replace circulating progenitors without affecting CNS-resident microglia, we found a strong correlation between monocyte infiltration and progression to the paralytic stage of EAE. Inhibition of chemokine receptor-dependent recruitment of monocytes to the CNS blocked EAE progression suggesting that these infiltrating cells are essential for pathogenesis. Finally, we found that although microglia can enter the cell cycle and return to quiescence following remission, recruited monocytes vanish, thus not ultimately contributing to the resident microglial pool. These findings collectively demonstrate that microglia constitute a unique myeloid cell population that are capable of long-term self-renewal within the CNS, and can respond to CNS trauma and degeneration by expanding in situ independently of the contribution of blood-derived myeloid precursors. Furthermore, two distinct subsets of myelomonocytic cells with unique roles in neuroinflammation and disease progression were identified under conditions where the blood-brain barrier is damaged and blood-derived leukocytes have access to the CNS parenchyma.

Middle stone age lithic technology at Mvumu, Niassa, Mozambique

description: Bibliography: p. 182-217.
description: For over ten years the origin of modern human behaviour has been the focus of the majority of Middle Stone Age (MSA) research in Africa. However, the analytical value of the modern behaviour concept has recently been questioned. Critics argue that studying less abstract MSA ecology and behavioural variability would better serve our understanding of the period, but such studies are hindered by the fragmentary and unevenly distributed nature of the fundamental aspects ofMSA archaeology. This thesis makes a step forward in filling the gaps in this record by presenting lithic technology from a final MSA open air site called Mvumu in the Niassa basin of northern Mozambique. The results suggest that Mvumu fits well with other Niassa basin sites and sites throughout the south-central African woodlands and forests suggests that Mvumu's lithic technology belongs to an overarching technological complex throughout the greater area.

description: For a fixed nonnegative integer $u$ and positive integer $n$, we investigate the symmetric function \[\sum_{d|n} \left(c_d(\tfrac{n}{d})\right)^u p_d^{\tfrac{n}{d}},\] where $p_n$ denotes the $n$th power sum symmetric function, and $c_d(r)$ is a Ramanujan sum, equal to the sum of the $r$th powers of all the primitive $d$th roots of unity. We establish the Schur positivity of these functions for $u=0$ and $u=1$, showing that, in each case, the associated representation of the symmetric group $\mathfrak{S}_n$ decomposes into a sum of Foulkes representations, that is, representations induced from the irreducibles of the cyclic subgroup generated by the long cycle. We also conjecture Schur positivity for the case $u= 2$.

INFLUENCE OF USING BONDING AGENT AND SHEAR STUDS ON BOND STRENGTH OF CONCRETE OVERLAYS ON PRESTRESSED SLABS
Creators: name: Sharma, Shubham
Publisher: name: Digital Repository at the University of Maryland
Year: 2018
Subjects: subject: Engineering

description: This study explores the effects of using bonding agent and shear studs in conjunction with a defined surface roughness condition on the bond strength of concrete overlays poured over prestressed concrete slabs. The shear bond and tensile bond strengths are tested for seven cases by using Double-L test and Split-Prism test respectively. The test variables are surface roughness, use of slurry mix, commercial bonding agent and shear studs at the interface. Application of grooves on the substrate provides a good bond owing to an interlocking effect. Application of bonding agent results in the lowest bond strengths by introduction of a plane of weakness. The bond strength values where shear studs are used are the highest of all test cases. Based on the findings from this study, a recommendation is made to Maryland Department of Transportation to use precast panels with pre-existing grooves and simply pour the overlay concrete on top.
Sub-picowatt resolution calorimetry with a bi-material microcantilever sensor

description: We have designed and fabricated bi-material microcantilevers with low conductance by minimizing the width and thickness of the cantilevers while keeping them suitable for detection with an optical deflection technique. The conductance of a cantilever is determined experimentally to be 330 ± 20 nWK−1. Using this cantilever, we have measured less than 1 pW of heat flow through the cantilever. The thermal noise-limited resolution of the cantilever is expected to be ≈ 50 fW. Such cantilevers give us additional tools to probe thermal transport through nanostructures, especially through single molecules where picowatt-level sensitivity is necessary.

It is shown that although there is an electron-hole asymmetry in the phase diagram, the electromagnetic response in the electron-doped cuprate superconductors is similar to that observed in the hole-doped cuprate superconductors. The superfluid density depends linearly on temperature, except for the strong deviation from the linear characteristics at the extremely low temperatures.

description: The Clifford spectrum is a form of joint spectrum for noncommuting matrices. This theory has been applied in photonics, condensed matter and string theory. In applications, the Clifford spectrum can be efficiently approximated using numerical methods, but this only is possible in low dimensional example. Here we examine the higher-dimensional spheres that can arise from theoretical examples. We also describe a constuctive method to generate five real symmetric almost commuting matrices that have a $K$-theoretical obstruction to being close to commuting matrices. For this, we look to matrix models of topological electric circuits.

Linguistic Orphan: Medical Literacy in Medieval England and the Erasure Of Anglo-Saxon Medical Knowledge

description: This thesis seeks to answer the question of why medieval physicians “forgot” efficacious medical treatments developed by the Anglo-Saxons and how Anglo-Saxon medical texts fell into obscurity. This thesis is largely based on the 2015 study of Freya Harrison et al., which replicated a tenth-century Anglo-Saxon eyesalve and found that it produced antistaphylococcal activity similar to that of modern antibiotics. Following an examination of the historiography, primary texts, and historical context, this thesis concludes that Anglo-Saxon medical texts, regardless of what useful remedies they contained, were forgotten primarily due to reasons of language: the obsolescence of Old English following the Norman Conquest, and the dominance of Latin in the University-based medical schools in medieval Europe.

description: We analyze Nf=2 nucleon mass data with respect to their dependence on the pion mass down to mpi = 157 MeV and compare it with predictions from covariant baryon chiral perturbation theory (BChPT). A novel feature of our approach is that we fit the nucleon mass data simultaneously with the directly obtained pion-nucleon sigma-term. Our lattice data below mpi = 435 MeV is well described by O(p^4) BChPT and we find sigma=37(8)(6) MeV for the sigma-term at the physical point. Using the nucleon mass to set the scale we obtain a Sommer parameter of r_0=0.501(10)(11) fm.

description: Spatially-resolved studies of the kinematics of galaxies provide crucial insights into their assembly and evolution, enabling to infer the properties of the dark matter halos, derive the impact of feedback on the ISM, characterize the outflow motions. To date, most of the kinematic studies at z=0.5-3.5 were obtained using emission lines tracing the warm, ionized gas. However, whether these provide an exhaustive or only a partial view of the dynamics of galaxies and of the properties of the ISM is still debated. Complementary insights on the cold gas kinematics are therefore needed. We present ALPAKA, a project aimed at gathering high-resolution observations of CO and [CI] emission lines of star-forming galaxies at z=0.5-3.5 from the ALMA public archive. With 147 hours of total integration time, ALPAKA assembles ~0.25'' observations for 28 star-forming galaxies, the largest sample with spatially-resolved cold gas kinematics as traced by either CO or [CI] at z>0.5. By combining multi-wavelength ancillary data, we derive the stellar masses ($M_{\star}$) and star-formation rates (SFR) for our targets, finding values of $M_{\star}\gtrsim 10^{10}$ M$_{\odot}$ and SFR of 10-3000 M$_{\odot}$/yr. A large fraction of ALPAKA galaxies (19/28) lie in overdense regions (clusters, groups, and protoclusters). We exploit the ALMA data to infer their dynamical state and we find that 19/28 ALPAKA galaxies are rotating disks, 2 are interacting systems, while for the remaining 7 sources the classification is uncertain. The disks have velocity dispersion values that are typically larger in the innermost regions than in the outskirts, with a median value for the entire disk sample of 35$^{+11}_{-9}$ km/s. Despite the bias of our sample towards galaxies hosting very energetic mechanisms, the ALPAKA disks have high ratios of ordered-to-random motion ($V/σ$) with a median value of 9$^{+7}_{-2}$.

description: Wildlife are used to monitor the presence and persistence of legacy organochlorine contaminants in the environment. In this study, bald eagles (Haliaeetus leucocephalus) were utilized as an indicator of exposure to organochlorine compounds at Voyageur’s National Park, Minnesota from 2011-2017. This demonstrated decreasing concentration trends and a lack of recent inputs of organochlorine compounds. However, the use of organochlorine compounds continues in other parts of the world. Therefore, a technique for using solid phase extraction to quantify organochlorine analytes in avian plasma was developed in order to facilitate international biomonitoring of these compounds. Using this method, organochlorine compounds are extracted from plasma and stored within extraction cartridges during transport from collection site to analysis site. This has important implications for international wildlife biomonitoring. If organochlorine analytes are separated from their matrix at the site of collection, sensitive or hazardous biological materials do not need to be transported or stored.

description: We expand the results of arXiv:1105.5165, where a holographic description of a conformal field theory defined on a manifold with boundaries (so called BCFT) was proposed, based on AdS/CFT. We construct gravity duals of conformal field theories on strips, balls and also time-dependent boundaries. We show a holographic g-theorem in any dimension. As a special example, we can define a `boundary central charge' in three dimensional conformal field theories and our holographic g-theorem argues that it decreases under RG flows. We also computed holographic one-point functions and confirmed that their scaling property agrees with field theory calculations. Finally, we give an example of string theory embedding of this holography by inserting orientifold 8-planes in AdS(4)xCP(3).

description: Lattice relaxation in twistronic bilayers with close lattice parameters and almost perfect crystallographic alignment of the layers results in the transformation of moiré pattern into a sequence of preferential stacking domains and domain wall networks. Here, we show that reconstructed moiré superlattices of the perfectly aligned heterobilayers of same-chalcogen transition metal dichalcogenides have broken-symmetry structures featuring twisted nodes ('twirls') of domain wall networks. Analysing twist-angle-dependences of strain characteristics for the broken-symmetry structures we show that the formation of twirl reduces amount of hydrostatic strain around the nodes, potentially, reducing their infuence on the band edge energies of electrons and holes.

Not only has unemployment and poverty in the region soared and output plummeted, but global growth has been seriously affected. Indeed, by some calculations, even assuming a relatively rapid return of the global economy to sustained growth, the total loss of output, relative to the previous trend path, is in the hundreds of billions of dollars.

description: The observed radial and vertical metallicity distribution of old stars in the Milky Way disk provides a powerful constraint on the chemical enrichment and dynamical history of the disk. We present the radial metallicity gradient, Δ[Fe/H]/ΔR, as a function of height above the plane, |Z|, using 7010 main sequence turnoff stars observed by the Sloan Extension for Galactic Understanding and Exploration (SEGUE) survey. The sample consists of mostly old thin and thick disk stars, with a minimal contribution from the stellar halo, in the region 6 < R < 16 kpc, 0.15 < |Z| < 1.5 kpc. The data reveal that the radial metallicity gradient becomes flat at heights |Z| > 1 kpc. The median metallicity at large |Z| is consistent with the metallicities seen in outer disk open clusters, which exhibit a flat radial gradient at [Fe/H] ~ -0.5. We note that the outer disk clusters are also located at large |Z|; because the flat gradient extends to small R for our sample, there is some ambiguity in whether the observed trends for clusters are due to a change in R or |Z|. We therefore stress the importance of considering both the radial and vertical directions when measuring spatial abundance trends in the disk. The flattening of the gradient at high |Z| also has implications on thick disk formation scenarios, which predict different metallicity patterns in the thick disk. A flat gradient, such as we observe, is predicted by a turbulent disk at high redshift, but may also be consistent with radial migration, as long as mixing is strong. We test our analysis methods using a mock catalog based on the model of Schönrich & Binney, and we estimate our distance errors to be ~25%. We also show that we can properly correct for selection biases by assigning weights to our targets.

The concentration results served as input into multi-zone ventilation models of the two buildings, which had different heating, ventilation, and air conditioning (HVAC) systems. The dormitory with a central mechanical ventilation system had, as expected, a higher turnover of fresh air compared to the other, which relied on exhaust fans and infiltration. This well-ventilated building also contained far fewer occupants with recorded upper respiratory illness incidence in comparison to the poorly ventilated building. The central ventilation system increased dorm room ventilation rates by 500%, while decreasing respiratory illness incidence by over 85%. Comparative studies have shown similar findings with increased ventilation reducing incidence of upper respiratory illness by an order of magnitude.

The East Asian Crisis: Lessons for Today and for Tomorrow: Introduction
Creators: name: Stiglitz, Joseph E.
Publisher: name: Columbia University

Subjects: Economics

description: What I have tried to do in these introductory remarks is to raise questions. I have also tried to put forward the fundamental hypothesis that, in fact - be it in recognizing the causes of the crisis, in predicting the crisis and, most importantly, in responding to the crisis - a lack of basic knowledge about economics and a lack of use of the available knowledge may have contributed to both the inability to anticipate and to deal with the crisis most effectively. The purpose of this conference, however, is not to go over the past - there have been a lot of debates over that; that is not the function. The function is to recognize that, as I said before, we will have crises in the future - no matter what we do, there will be crises - and we will have to face the challenge of how to deal with them. Thus, unless we can answer the kinds of questions that I have posed above, we will not be able to deal with future crises in the way which most effectively maintains the strength of these economies. As we move forward, we must remember that those policies formulated to respond to the crisis - if they have not contributed to aggravate it - have failed to stymie enormous recessions and/or depressions. Even worse, these policies have adversely affected, with disproportionate intensity, the workers and the small businesses who had not engaged in international financial market speculation. These were innocent by-standers who, in some sense, have borne a huge part of the brunt of the adjustment, without having themselves enjoyed any of the fruits of the economic policies that led to the crisis or being party to the packages to respond to the crisis.

description: Nitric oxide (NO) is a gas that serves as a ubiquitous signaling molecule participating in physiological activities of various organ systems. Nitric oxide is produced in the endocrine pancreas and contributes to synthesis and secretion of insulin. The potential role of NO in insulin secretion is disputable – both stimulatory and inhibitory effects have been reported. Available data indicate that effects of NO critically depend on its concentration. Different isoforms of NO synthase (NOS) control this and have the potential to decrease or increase insulin secretion. In this review, the role of NO in insulin secretion as well as the possible reasons for discrepant findings are discussed. A better understanding of the role of NO system in the regulation of insulin secretion may facilitate the development of new therapeutic strategies in the management of diabetes.

Understanding the nature of "superhard graphite"

description: Numerous experiments showed that on cold compression graphite transforms into a new superhard and transparent allotrope. Several structures with different topologies have been proposed for this phase. While experimental data are consistent with these models, the only way to solve this puzzle is to find which structure is kinetically easiest to form. Using state-of-the-art molecular-dynamics transition path sampling simulations, we investigate kinetic pathways of the pressure-induced transformation of graphite to various superhard candidate structures. Unlike hitherto applied methods for elucidating nature of superhard graphite, transition path sampling realistically models nucleation events necessary for physically meaningful transformation kinetics. We demonstrate that nucleation mechanism and kinetics lead to $M$-carbon as the final product. $W$-carbon, initially competitor to $M$-carbon, is ruled out by phase growth. Bct-C$_4$ structure is not expected to be produced by cold compression due to less probable nucleation and higher barrier of formation.

Taxation, Public Policy, and Dynamics of Unemployment
Creators: name: Stiglitz, Joseph E.
Publisher: name: Columbia University
Year: 1999
Subjects: Economics

description: This paper provides an overview of the key issues relating to taxation, public policy and the dynamics of unemployment. It takes issue with the widely held view that generous social insurance schemes and the associated high payroll taxes have been the major cause of the high unemployment rates which have persisted in Europe over the past 15 years. It puts forward a framework for a theory of adjustment, based on the portfolio theory of the risk averse firm and the efficiency wage theory of labor markets. This is used to explain why in the onset of a downturn, the hiring rate may lag the layoff rate, thus giving rise to rising unemployment rates. It is also shown to provide guidance as to policies which enhance the ability of firms to bear risks and which reduce costs of hiring and firing. The paper argues that while policies which increase severance or layoff costs may be well intended they may actually serve to exacerbate the magnitude of employment fluctuations. Similarly, unemployment compensation, which is designed to ease the burden on those who are unemployed, may lead to higher levels of equilibrium unemployment. These programs can be restructured in ways which simultaneously ease the short-run burden of those thrown into unemployment, while reducing the adverse impact of these programs on the unemployment rate.

description: Unlike conventional materials that covalent bonds connecting atoms as the major force to hold the materials together, supramolecular biomaterials rely on noncovalent intermolecular interactions to assemble. The reversibility and biocompatibility of supramolecular biomaterials render them with diverse range of functions and lead to rapid development in the past two decades. This review focuses on the noncovalent and enzymatic control of supramolecular biomaterials, with the introduction to various triggering mechanism to initiate self-assembly. Representative applications of supramolecular biomaterials are highlighted in four categories: tissue engineering, cancer therapy, drug delivery, and molecular imaging. By introducing various applications, we intend to show enzymatic control and noncovalent interactions as a powerful tool for achieving spatiotemporal control of biomaterials both in vitro and in vivo for biomedicine.

The brownfield market failure in Canada: strategies for cleaning up contaminated sites
Creators: name: Omura, Robert K.
Publisher: name: Law
Year: 2011

description: Bibliography: p. 201-235
description: A major obstacle to the goal of sustainable urban development has been the ongoing presence of historic contamination. No one wants to live, work or play next to contaminated land. These so-called brownfield sites often remain abandoned and underutilized lands that could be put to higher or better uses if the longstanding problem of contamination is addressed. This thesis identifies key factors underlying the brownfield market failure and discusses ways to correct the market failure. This thesis looks at improved information through capacity building, fixing structural problems associated with the regulatory system, such as the way liability rules operate within environmental legislation, and a sustainable development approach through greater municipal action. It attempts to integrate current theories of liability with the regulatory framework under federal, provincial and municipal law, and discusses the rapid expansion of municipal activism as a good approach to an effective brownfield strategy.

description: Bibliography: p. 103-106
description: The main objective of this project is to analyze the possibility of implementing and adapting the Common European Framework of Reference (CEFR) into the Canadian context and apply it to the Spanish program at the University of Calgary. The methodology includes comparing the levels of the Spanish courses taught at this university with the "Plan Curricular del Instituto Cervantes: Niveles de referencia para el espaiiol" by the Cervantes Institute in 2006. The Reference Level Descriptors (RLD) will be compared with the individual levels of courses at the Spanish Department (levels 200, 300, 400 and 500) in order to determine where within the individual courses, Reference Levels begin and end. The last part of the thesis will explore the suggestions and steps to be taken towards the integration of the CEFR into the program in order to optimize the program and gain further recognition within and outside of the country.
