Glass painting and staining--Conservation and restoration
Historic preservation

description: A stained glass window is both an architectural building element and an individual work of art. Like architecture, a stained glass window is composed of a variety of materials, mainly glass, lead, and surface decoration, each of which has its own conservation issues. Surface decoration, which includes vitreous glass paint, silver stain, and enamels, is the component of a stained glass window that is sometimes underappreciated. While it may not pose a major threat to the physical stability of the window or the safety of the window’s environment, it is the decoration that defines the windows as works of art, with imagery that holds the window’s history, including a direct view into the traditions, ideals, and beliefs of the people of their time. The conservation of the surface decoration of stained glass windows has never been fully analyzed, and both glazing and conservation professionals are constantly seeking information regarding the history of the materials and techniques used in order to create or restore a stained glass window. With conservation, the methods and techniques used to maintain and conserve the decoration will vary depending on a number of circumstances, including the location of the window, the history and traditions of the people involved, and the tools available to the conservators. As with all conservation fields, there are also ethical considerations to address in order to be sure that the authenticity of each work is maintained. For this history, it is also important to note the past restoration techniques used on these types of decoration, as well as what is being used today. This includes successes and failures, both of which bring essential information to the conservator. Each window brings with it an entirely new history and set of decoration conservation problems so there are no universal solutions for this field. Stained glass is a fascinating field because it combines the worlds of art and architecture with a single object and the surface decoration plays an important role in this. By analyzing the history and techniques of these three surface decorations, it is possible to not only preserve an underappreciated element inherent to these historic stained glass windows, but also the overall aesthetic of true works of art that serve to enhance the buildings in which they reside.

description: The response of a linear system to an external perturbation is governed by the Fourier limit, with the inverse of the interaction time constituting a lower limit for the system bandwidth. This does not hold for nonlinear systems, which can thus exhibit sub-Fourier behavior. The present work identifies a mechanism for sub-Fourier sensitivity in driven quantum systems, which relies on avoided crossing between Floquet states. Features up to three orders of magnitude finer than the Fourier limit are presented.

description: Introduction: Health professions educators are increasingly called upon to apply an evidence-informed approach to teaching and assessment practices. There is scant empirical research exploring educators’ attitudes, practices, and perceived barriers and supports to using research evidence in educational practice. Methods: We conducted a survey of AMEE members to explore three domains related to evidence-informed health professions education: (1) attitudes; (2) practices; and (3) supports and barriers. Analyses involved descriptive statistics to characterize participants' responses per domain. Chi-Square statistics were carried out to examine differences among the demographic variables on a subset of items in each of the three survey sections. Results: Three hundred ninety-six (∼10%) participants representing health professions educators (HPEs) and non HPEs (e.g. PhDs) and different roles (e.g. teacher, administrator) completed the survey. Attitudes toward evidence-informed HPE were generally favorable. Several barriers preclude participants from engaging in evidence-informed approaches to health professions education (HPE). Discussion: This study provides preliminary evidence on the attitudes toward and perceived barriers and supports of research use in HPE from different groups of HP educators, clinicians, and administrators. The findings for each of the three domains require additional exploration using qualitative methodologies. Conclusion: Targeted interventions designed to increase the uptake of research in HPE should consider different stakeholder groups’ perceptions regarding these approaches, current vs. best practices, and factors that may impede evidence-informed approaches.

description: We observe that every self-dual ternary code determines a holomorphic N=1 superconformal field theory. This provides ternary constructions of some well-known holomorphic N=1 SCFTs, including Duncan's "supermoonshine" model and the fermionic "beauty and the beast" model of Dixon, Ginsparg, and Harvey. Along the way, we clarify some issues related to orbifolds of fermionic holomorphic CFTs. We give a simple coding-theoretic description of the supersymmetric index and conjecture that for every self-dual ternary code this index is divisible by 24; we are able to prove this conjecture except in the case when the code has length 12 mod 24. Lastly, we discuss a conjecture of Stolz and Teichner relating N=1 SCFTs with Topological Modular Forms. This conjecture implies constraints on the supersymmetric indexes of arbitrary holomorphic SCFTs, and suggests (but does not require) that there should be, for each k, a holomorphic N=1 SCFT of central charge 12k and index 24/gcd(k,24). We give ternary code constructions of SCFTs realizing this suggestion for k \leq 5.

When Can Nonconvex Optimization Problems be Solved with Gradient Descent? A Few Case Studies

Neural networks (Computer science)

Nonconvex programming

description: Gradient descent and related algorithms are ubiquitously used to solve optimization problems arising in machine learning and signal processing. In many cases, these problems are nonconvex yet such simple algorithms are still effective. In an attempt to better understand this phenomenon, we study a number of nonconvex problems, proving that they can be solved efficiently with gradient descent. We will consider complete, orthogonal dictionary learning, and present a geometric analysis allowing us to obtain efficient convergence rate for gradient descent that hold with high probability. We also show that similar geometric structure is present in other nonconvex problems such as generalized phase retrieval. Turning next to neural networks, we will also calculate conditions on certain classes of networks under which signals and gradients propagate through the network in a stable manner during the initial stages of training. Initialization schemes derived using these calculations allow training recurrent networks on long sequence tasks, and in the case of networks with low precision activation functions they make explicit a tradeoff between the reduction in precision and the maximal depth of a model that can be trained with gradient descent. We finally consider manifold classification with a deep feed-forward neural network, for a particularly simple configuration of the manifolds. We provide an end-to-end analysis of the training process, proving that under certain conditions on the architectural hyperparameters of the network, it can successfully classify any point on the manifolds with high probability given a sufficient number of independent samples from the manifold, in a timely manner. Our analysis relates the depth and width of the network to its fitting capacity and statistical regularity respectively in early stages of training.

description: The research scope of this paper is to apply spatial object based image analysis (OBIA) method for processing panchromatic multispectral image covering study area of Brussels for urban mapping. The aim is to map different land cover types and more specifically, built-up areas from the very high resolution (VHR) satellite image using OBIA approach. A case study covers urban landscapes in the eastern areas of the city of Brussels, Belgium. Technically, this research was performed in eCognition raster processing software demonstrating excellent results of image segmentation and classification. The tools embedded in eCognition enabled to perform image segmentation and objects classification processes in a semi-automated regime, which is useful for the city planning, spatial analysis and urban growth analysis. The combination of the OBIA method together with technical tools of the eCognition demonstrated applicability of this method for urban mapping in densely populated areas, e.g. in megapolis and capital cities. The methodology included multiresolution segmentation and classification of the created objects.

description: Nonconvex optimization is NP-hard, even the goal is to compute a local minimizer. In applied disciplines, however, nonconvex problems abound, and simple algorithms, such as gradient descent and alternating direction, are often surprisingly effective. The ability of simple algorithms to find high-quality solutions for practical nonconvex problems remains largely mysterious.
      This thesis focuses on a class of nonconvex optimization problems which CAN be solved to global optimality with polynomial-time algorithms. This class covers natural nonconvex formulations of central problems in signal processing, machine learning, and statistical estimation, such as sparse dictionary learning (DL), generalized phase retrieval (GPR), and orthogonal tensor decomposition. For each of the listed problems, the nonconvex formulation and optimization lead to novel and often improved computational guarantees.
      This class of nonconvex problems has two distinctive features: (i) All local minimizer are also global. Thus obtaining any local minimizer solves the optimization problem; (ii) Around each saddle point or local maximizer, the function has a negative directional curvature. In other words, around these points, the Hessian matrices have negative eigenvalues. We call smooth functions with these two properties (qualitative) X functions, and derive concrete quantities and strategy to help verify the properties, particularly for functions with random inputs or parameters. As practical examples, we establish that certain natural nonconvex formulations for complete DL and GPR are X functions with concrete parameters.
      Optimizing X functions amounts to finding any local minimizer. With generic initializations, typical iterative methods at best only guarantee to converge to a critical point that might be a saddle point or local maximizer.  Interestingly, the X structure allows a number of iterative methods to escape from saddle points and local maximizers and efficiently find a local minimizer, without special initializations. We choose to describe and analyze the second-order trust-region method (TRM) that seems to yield the strongest computational guarantees. Intuitively, second-order methods can exploit Hessian to extract negative curvature directions around saddle points and local maximizers, and hence are able to successfully escape from the saddles and local maximizers of X functions. We state the TRM in a Riemannian optimization framework to cater to practical manifold-constrained problems. For DL and GPR, we show that under technical conditions, the TRM algorithm finds a global minimizer in a polynomial number of steps, from arbitrary initializations.

description: The ‘populist phenomenon’ has received a lot of attention in recent years. Yet little is known about the populists themselves: who are they? They are often described as bad-mannered provocateurs disrupting the political game, but also as charismatic leaders able to persuade and motivate. Can a populist ‘style’ or ‘personality’ be identified? This article assesses to what extent populists score differently from ‘mainstream’ politicians on established personality inventories. Using a new dataset based on expert ratings for 152 candidates (including 33 populists) having competed in 73 elections worldwide, it is found that populists score lower on agreeableness, emotional stability and conscientiousness. At the same time, populists score higher on extraversion, narcissism, psychopathy and Machiavellianism. These results have important implications for the study of the success of populists in contemporary democracies and beyond.

description: Let $Γ$ be a torsion free lattice in $G = \PGL(n+1,\FF)$, where $n\ge 1$ and $\FF$ is a non-archimedean local field. Then $Γ$ acts on the Furstenberg boundary $G/P$, where $P$ is a minimal parabolic subgroup of $G$. The identity element $\id$ in the crossed product $C^*$-algebra $C(G/P)\rtimes Γ$ generates a class $[\id]$ in the $K_0$ group of $C(G/P)\rtimes Γ$. It is shown that $[\id]$ is a torsion element of $K_0$ and there is an explicit bound for the order of $[\id]$. The result is proved more generally for groups acting on affine buildings of type $\tA_n$. For $n=1, 2$ the Euler-Poincaré characteristic $χ(Γ)$ annihilates the class $[\id]$.

description: This dissertation provides a novel evaluation of the extent to which, and the conditions under which United States administrative agencies are able to push policy toward their preferences rather than being wholly faithful to their legislative principals, in ways that I refer to as noncompliance. I evaluate this bureaucratic behavior in the context of the Environmental Protection Agency and the Department of Interior from 1973 to 2010. I collected extensive original data on institutional responses to these agency actions, and using these new data found robust support for the core separation-of-powers hypotheses that legislative-executive conflict, polarization in Congress, and disagreement with the delegating legislation powerfully contribute to agencies stepping outside their discretionary windows rather than exercising regulatory compliance. To evaluate the policy consequences of this bureaucratic behavior with respect to policy volatility and long-term bureaucratic discretion to implement public policy, I created an additional original dataset of statutory amendments to the legislation under the jurisdiction of the Environmental Protection Agency. I find strong support for noncompliance in the prior period leading Congress to considerably revise agency discretion in the way of adding specificity to the texts or imposing additional oversight provisions that constrain agency actions moving forward. Thus, agencies' willingness to step outside of their discretionary windows so as to achieve shorter-term policy goals has important longer-term consequences with respect to their range of discretion and the scope of administrative capacity in a world of bureaucratic governance. The dissertation has broad implications for our understanding of the factors shaping de facto policy outcomes in a conflictual separation-of-powers setting, and the evolving scope of the American administrative state.

description: We consider the evaporation of the (shell focusing) naked singularity formed during the self-similar collapse of a marginally bound inhomogeneous dust cloud, in the geometric optics approximation. We show that, neglecting the back reaction of the spacetime, the radiation on $\scrip$ tends to infinity as the Cauchy Horizon is approached. Two consequences can be expected from this result: (a) that the back reaction of spacetime will be large and eventually halt the formation of a naked singularity thus preserving the Cosmic Censorship Hypothesis and (b) matter attempting to collapse into a naked singularity will radiate away energy at an intense rate, thereby possibly providing experimental signatures of quantum effects in curved spacetimes.

description: Two theoretical models for the description of the diffraction properties of gradient crystals have been developed, one in the framework of the kinematic theory, the other within a transfer matrix formalism based on the dynamical theory of diffraction. A matrix describes the coupling and the propagation of the forward- and the Bragg-diffracted wave functions through a plane, parallel crystal lamella. It applies for the description of any crystalline medium with changes of the diffraction properties along the direction of the surface normal. Experimentally a crystal growth technique has been set up to produce novel Si1-xGex gradient crystals with 0 < x < 0.4 on a large surface and with growth rates of up to 0.6 um/min. Layer thicknesses of several 100 um have been achieved. A tetragonal distortion attributed to different thermal expansion coefficients has been discovered. The anisotrope mosaic distribution gives evidences for the existence of misfit dislocations. The reflection curves calculated by the transfer matrix method fit well the experimental results. The diffraction data show an intensity increase of 25 related to the experimental resolution function. Comparing this value with the calculated reflectivity for perfect silicon, this factor increases to 40.

description: Domain structure of paracetamol -- popular antipyretic analgesic -- was investigated by infrared (IR) spectroscopy using synchrotron radiation. Absorbance and retardance maps reveal molecular orientation inside the micro-domains of the paracetamol form II which has a better water solubility and compressibility compared to the commercially used forms I. The developed method of analysis representing orientation of optical slow(fast)-axis is compared with azimuthal orientation of the absorbance at several specific IR bands using vector maps. High brightness of synchrotron radiation and hyper-spectral mapping of structural domains in paracetamol clearly reveals the domain boundaries and can potentially be used to observe \emph{in situ} intra-phase transformations of paracetamol forms-I, II, III and melting, which are important for making medical tablets and powders by an industrial process.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: A novel series of fused acridine containing 1,2,4-triazole derivatives (13a-j) have been synthesized and their structures were confirmed by 1HNMR, 13CNMR and mass spectral data. Further, all these derivatives were tested for their anticancer activity against four human cancer cell lines A549 (Lung), MCF7 (Breast), A375 (Melanoma) and HT-29 (Colon). The IC50 values range of target compounds shown 0.11 ± 0.02 to 13.8 ± 0.99 µM as compared with standard drug range 0.11 ± 0.02 to 0.93 ± 0.056 µM. Among them, compounds 13d, 13f, 13g, 13h, 13i, and 13j were exhibited more potent activity. Docking simulation was performed as a trial to study the mechanisms and binding modes of these compounds towards the DNA target. The results showed these compounds have intercalated placement in the active sites and stable interactions similar to the co-crystallized reference ligand. Further, these compounds (13a-j) were investigated for Drug-likeness, ADME properties and Toxicity risk assessment.

description: A new (scalar) spectral decomposition is found for the Dirac system in two dimensions associated to the focusing Davey--Stewartson II (DSII) equation. Discrete spectrum in the spectral problem corresponds to eigenvalues embedded into a two-dimensional essential spectrum. We show that these embedded eigenvalues are structurally unstable under small variations of the initial data. This instability leads to the decay of localized initial data into continuous wave packets prescribed by the nonlinear dynamics of the DSII equation.

description: We explore orbit properties of 35 prolate-triaxial galaxies selected from the Illustris cosmological hydrodynamic simulation. We present a detailed study of their orbit families, and also analyse relations between the relative abundance of the orbit families and the spin parameter, triaxiality, the ratio of the angular momentum and the baryon fraction. We find that box orbits dominate the orbit structure for most prolate-triaxial galaxies, especially in the central region. The fraction of irregular orbits in the prolate-triaxial galaxies is small, and it increases with galaxy radius. Both the x-tube and z-tube orbits are important in prolate-triaxial galaxies, especially in the outer regions. The fraction of box orbits for prolate-triaxial galaxies ($0.7

description: We investigate if physical laws can impose limit on computational time and speed of a quantum computer built from elementary particles. We show that the product of the speed and the running time of a quantum computer is limited by the type of fundamental interactions present inside the system. This will help us to decide as to what type of interaction should be allowed in building quantum computers in achieving the desired speed.

description: The Arts & Culture (A&C) District is supported in part by the adjacent population of students, staff and residents who live within the neighbouring area. This report aims to identify the gaps and opportunities for increasing the attendance and participation of this demographic at events within the A&C District. These were identified through data gathered at pop-up engagements conducted in the NEST and Orchard Commons. These engagements consisted of three interactive boards, where participants would respond to a series of questions with sticky notes, and informal interviews, where a broader understanding would be gained of the participants ‘sticky note’ responses. By the time the pop-up engagements had concluded, over 50 individuals had been engaged with, and approximately 200 unique responses had been received. After performing a thematic analysis of those responses, several key findings were determined. These findings were grouped together under the themes: (1) Advertising, Marketing and Coverage, (2) Theme and Appeal of Events, (3) Affordability and Financial Constraints, (4) Psychosocial and Behavioral Factors, (5) Venue and Timing, and (6) Other Commitments. From these findings, several short term and long term recommendations emerged. In the short term, it is recommended that content advertising and outreach strategies have a focus on social media and online presence opposed to traditional print media. In addition, awareness about event incentives should be increased and attendance data for events within the A&C District should be coordinated and collected. As for the long term, it is recommended that an A&C identity be developed throughout campus and that events be increasingly student-led as well as impromptu or drop. Events should also be considered that contain social interaction and meeting new people as part of the event.

description: Background: Neighborhood disadvantage (ND) and population density (PD) are two community characteristics contextualizing friends’ influence on adolescent alcohol use. However, these community characteristics are rarely examined for potential joint contributions, although it is possible that the way friends are selected or influence alcohol use are shaped by both ND and PD. In addition, prior studies examining ND or PD contexts on friend influence rarely discern between socialization and selection. Objectives: The current study examined how selection and socialization influences on adolescent alcohol use are shaped by unique and joint contexts of ND and PD. Methods: Adolescents from Waves I and II of the National Longitudinal Study of Adolescent and Adult Health (Add Health) were included in three models assessing friends’ socialization of alcohol us initiation and binge drinking, and selection of drinking friends. ND and PD were tested for mediation and moderation individually and jointly. Results: Results indicated that socialization of drinking initiation was stronger in high ND contexts, and that continued binge drinking was stronger in low ND contexts. PD indirectly influenced socialization of initiation and binge drinking maintenance via a negative association with number of drinking friends. PD and ND jointly influenced the association between initial binge drinking and next-year selection of drinking friends, such that selection was stronger within areas related to lower levels of drinking friends. Conclusions/Importance: Current results indicate that PD and ND shape friends’ influence on alcohol use in unique ways. These must be accounted for to better understand bidirectional effects of friend influence.
When Nature Meets Human Nature: Essays on the Social Impacts of Energy Infrastructure and Environmental Policy

description: A key challenge confronting modern policymakers is to ensure that economic development is both socially just and environmentally sustainable. Toward that goal, effective government regulations require the accurate quantification of their associated costs and benefits. An extensive theoretical and empirical literature in economics has shown the benefits of government policies in addressing market failures and providing public goods. But few studies have credibly identified the social costs and distributional impacts of existing policies. My dissertation integrates new data and empirical methods from economics and earth sciences to investigate the social impacts of energy infrastructure and environmental policy. Chapter 1 uses the Three Gorges Dam in China as a natural experiment to provide the first evidence of the social and economic impacts of dam-induced inundation on population displacement and labor market reallocation. Chapter 2 examines the political economy implications of wind turbine construction on United States congressional elections. Chapter 3 employs original data from a large-scale survey to study the social benefits of environmental quality improvements. Overall, results from these papers inform future research on the social impacts of energy and environmental policy and highlight the importance of unbiased policy evaluations.

description: Quantitative computed tomography (QCT) is a widely used tool for osteoporosis diagnosis and monitoring. The assessment of cortical markers like cortical bone mineral density (BMD) and thickness is a demanding task, mainly because of the limited spatial resolution of QCT. We propose a direct model based method to automatically identify the surface through the center of the cortex of human vertebra. We develop a statistical bone model and analyze its probability distribution after the imaging process. Using an as-rigid-as-possible deformation we find the cortical surface that maximizes the likelihood of our model given the input volume. Using the European Spine Phantom (ESP) and a high resolution μCT scan of a cadaveric vertebra, we show that the proposed method is able to accurately identify the real center of cortex ex-vivo. To demonstrate the in-vivo applicability of our method we use manually obtained surfaces for comparison.

description: Numerical investigation of a class of inhomogeneous cosmological spacetimes shows evidence that at a generic point in space the evolution toward the initial singularity is asymptotically that of a spatially homogeneous spacetime with Mixmaster behavior. This supports a long-standing conjecture due to Belinskii et al. on the nature of the generic singularity in Einstein's equations.
