description: We develop a quantum Monte Carlo procedure, in the valence bond basis, to measure the Renyi entanglement entropy of a many-body ground state as the expectation value of a unitary {\it Swap} operator acting on two copies of the system. An improved estimator involving the ratio of {\it Swap} operators for different subregions enables simulations to converge the entropy in a time polynomial in the system size. We demonstrate convergence of the Renyi entropy to exact results for a Heisenberg chain. Finally, we calculate the scaling of the Renyi entropy in the two-dimensional Heisenberg model and confirm that the Néel groundstate obeys the expected area law for systems up to linear size L=28.

description: The Unlimited Sensing Framework (USF) was recently introduced to overcome the sensor saturation bottleneck in conventional digital acquisition systems. At its core, the USF allows for high-dynamic-range (HDR) signal reconstruction by converting a continuous-time signal into folded, low-dynamic-range (LDR), modulo samples. HDR reconstruction is then carried out by algorithmic unfolding of the folded samples. In hardware, however, implementing an ideal modulo folding requires careful calibration, analog design and high precision. At the interface of theory and practice, this paper explores a computational sampling strategy that relaxes strict hardware requirements by compensating them via a novel, mathematically guaranteed recovery method. Our starting point is a generalized model for USF. The generalization relies on two new parameters modeling hysteresis and folding transients} in addition to the modulo threshold. Hysteresis accounts for the mismatch between the reset threshold and the amplitude displacement at the folding time and we refer to a continuous transition period in the implementation of a reset as folding transient. Both these effects are motivated by our hardware experiments and also occur in previous, domain-specific applications. We show that the effect of hysteresis is beneficial for the USF and we leverage it to derive the first recovery guarantees in the context of our generalized USF model. Additionally, we show how the proposed recovery can be directly generalized for the case of lower sampling rates. Our theoretical work is corroborated by hardware experiments that are based on a hysteresis enabled, modulo ADC testbed comprising off-the-shelf electronic components. Thus, by capitalizing on a collaboration between hardware and algorithms, our paper enables an end-to-end pipeline for HDR sampling allowing more flexible hardware implementations.

description: The technological performances of metallic compounds are largely influenced by atomic ordering. Although there is a general consensus that successful theories of metallic systems should account for the quantum nature of the electronic glue, existing non-perturbative high-temperature treatments are based on effective classical atomic Hamiltonians. We propose a solution for the above paradox and offer a fully quantum mechanical, though approximate, theory that on equal footing deals with both electrons and ions. By taking advantage of a coarse grained formulation of the density functional theory [Bruno et al., Phys. Rev. B 77, 155108 (2008)] we develop a MonteCarlo technique, based on an ab initio Hamiltonian, that allows for the efficient evaluation of finite temperature statistical averages. Calculations of the relevant thermodynamic quantities and of the electronic structures for CuZn and Ni$_3$V support that our theory provides an appropriate description of order-disorder phase transitions.

Preliminary inquiries in crisis management
Creators: name: Smart, Carolyne Faith
Publisher: name: University of British Columbia
Year: 2010

description: This paper analyzes the process of crises decision making in organizations through three stages: a) precrisis, b) crisis management, c) post crisis. At each stage the behavior of the organization (in particular the decision unit) is diagnosed and certain pathologies noted. The later portion of the paper offers some prescriptions to attempt to correct these pathologies. Analysis of the stage of precrisis is characterized by an assessment of the probability that an organization will find itself in crisis. An organization may be threatened by an event occurring in its environment. Certain conditions make some organizations particularly vulnerable to threats. The probable objective impact of a threat on organizational goals is evaluated. If the event is perceived as a :. threat by the organization, it has the choice of two responses, either routine or crisis mode. If the event is characterized by high stress, shortened decision time and is a surprise to the organization, then a crisis will be triggered. Once a crisis occurs, organizations attempt to manage it. A repertoire of management styles and postures are available to choose from, depending upon the objectives of the organization and the dynamics of the system to which it belongs. The internal.dynamics of the decision unit are examined and in particular a number of pathologies are noted. As groups attempt to manage crises they quite often make poor decisions as a result of, a) premature consensus, b) information distortion, c) errors in judgment and d) implementation difficulties. Post crisis and the realignment of organizational systems and resources marks the final stage of crisis. The attributes of a crises disaster are examined.
Crafting and Forging The Black Diaspora: Black Histories in Jewelry

description: Often historical studies on jewelry are often focused on Eurocentric traditions especially in the Americas, this project seeks to reveal the transnational legacies of jewelry artists and makers in the Black Diaspora of the Americas. There are several questions guiding this study including; What are Black contributions in metalwork as craft, and how have Blacks used metal in the Diaspora? My interests are in jewelry or adornments—the objects we wear on different parts of the body and that often reflect aspects of cultural identity. Yet, I am also interested in probing the question, “What is Black American jewelry?” This project couples methodological and epistemological frameworks honed in archival studies, arts based research, art conservation science, (technical) art history, Black-centered material culture, and technical studies on historical objects. Through this diverse range of theoretical viewpoints this thesis project seeks to introduce readers to the diverse range of; material interests/mnemonics, fabrication/technical abilities, and the socio-cultural functionality of the objects these artists create. This project does not seek to serve as a definitive study on all of Black Diasporic jewelry, instead it seeks to propose a wide range of methodological tools that could be used for engaging in further research and scholarship on Black jewelry.

description: The above factors emphasize the scope of this thesis for further investigations on zirconia, the
improvement of all-ceramic zirconia restorations, and especially the interaction of zirconia
and veneering and its influence on the performance of the whole restoration.

The introduction, chapter 1, gave a literature overview on zirconia ceramics.

In chapter 2, the objective of the study was to evaluate the effect of abrading before and after sintering using alumina-based abrasives on the surface of yttria-tetragonal zirconia polycrystals. Particular attention was paid to the amount of surface stress–assisted phase transformation (tetragonal→monoclinic) and the presence of microcracks.

Chapter 3 is based on the idea that the conventional sintering techniques for zirconia based materials, which are commonly used in dental reconstruction, may not provide a uniform heating, with consequent generation of microstructural flaws in the final component. As a consequence of the sintering system, using microwave heating, may represent a viable alternative. The purpose of the study was to compare the dimensional variations and physical and microstructural characteristics of commercial zirconia (Y-TZP), used as a dental restoration material, sintered in conventional and microwave furnaces. 

Chapter 4 described the effect of sandblasting before and after sintering on the surface roughness of zirconia and the microtensile bond strength of a pressable veneering ceramic to zirconia.
Permutation classes, sorting algorithms, and lattice paths

description: A permutation is said to avoid a pattern if it does not contain any subsequence which is order-isomorphic to it. Donald Knuth, in the first volume of his celebrated book "The art of Computer Programming", observed that the permutations that can be computed (or, equivalently, sorted) by some particular data structures can be characterized in terms of pattern avoidance. In more recent years, the topic was reopened several times, while often in terms of sortable permutations rather than computable ones.
The idea to sort permutations by using one of Knuth’s devices suggests to look for a deterministic procedure that decides, in linear time, if there exists a sequence of operations which is able to convert a given permutation into the identical one.
In this thesis we show that, for the stack and the restricted deques, there exists an unique way to implement such a procedure. Moreover, we use these sorting procedures to create new sorting algorithms, and we prove some unexpected commutation properties between these procedures and the base step of bubblesort. We also show that the permutations that can be sorted by a combination of the base steps of bubblesort and its dual can be expressed, once again, in terms of pattern avoidance.
In the final chapter we give an alternative proof of some enumerative results, in particular for the classes of permutations that can be sorted by the two restricted deques. It is well-known that the permutations that can be sorted through a restricted deque are counted by the Schrӧder numbers. In the thesis, we show how the deterministic sorting procedures yield a bijection between sortable permutations and Schrӧder paths.

description: In this paper we propose a new design paradigm, which employing a postprocessing internal model unit, to approach the problem of output regulation for a class of multivariable minimum-phase nonlinear systems possessing a partial normal form. Contrary to previous approaches, the proposed regulator handles control inputs of dimension larger than the number of regulated variables, provided that a controllability assumption holds, and can employ additional measurements that need not to vanish at the ideal error-zeroing steady state, but that can be useful for stabilization purposes or to fulfil the minimum-phase requirement. Conditions for practical and asymptotic output regulation are given, underlying how in postprocessing schemes the design of internal models is necessarily intertwined with that of the stabilizer.

description: The ability to extract three-dimensional information from data obtained from the surface of a material is a fundamental problem in the field of non-destructive testing.In particular two-dimensional images obtained from a scanning electron microscope (SEM) contain depth information due to the fact that an energetic electron beam produces back-scattered electrons from different depths of the sample, dependent on the beam energy. The main idea behind the work contained in the thesis is that from images obtained from electron beams of different energies over the same area of the surface of a material, three-dimensional density information about the sample can be determined. The reconstruction technique needs to be robust becausethe material density is not generally a continuous function of position as the material may contain voids or inclusions of particles of a material of different density. The reconstruction technique involved analysing the contrast of the different SEM images produced at the different energies. The images were discretised into pixels, and the interior of the material discretised into voxels whose surface area matched the pixels of the images. Mathematical techniques were then used to determine the density of the material in the voxels. The density of the material in the voxels was determined by generating random values, based on Markov Chain Monte Carlo methods, projecting them in a similar way to what a microscope would do and judging the likelihood of the random values being a true representation by comparing the projections with the image data.

description: In der Medizin (wie auch in anderen Fächern) wächst generell die Bedeutung informatischer Expertise. Schon das erfordert eine Kultur interdisziplinärer Begutachtung, auf welche medizinische Ethikkommissionen nicht gut eingestellt sind. Mit dem Einsatz von Big Data- und KI-Verfahren (sei es eigens entwickelter, sei es in Form von „Tools“) sind weitere Herausforderungen für die forschungsethische Begutachtung verbunden. Die Autoren schildern die Problemlage und schlagen vor, sie durch Verfahrensänderungen zu lösen. Besser als die Befassung zweier Kommissionen scheint eine Begutachtung geeignet zu sein, die von vornherein interdisziplinär verfährt. Das zöge allerdings die Forderung nach sich, die Zusammensetzung medizinischer Ethikkommissionen zu ändern. Weil Fragen nach der Organisation forschungsethischer Begutachtungen auch solche nach Kriterien aufrufen, denen diese zu folgen hat, stellt der Beitrag zudem erste Schritte zu einer Konsolidierung der Kriterien für eine forschungsethische Begutachtung von Big Data- und KI-Projekten vor.

description: This paper presents the data-driven techniques and methodologies used to predict the remaining useful life (RUL) of a fleet of aircraft engines that can suffer failures of diverse nature. The solution presented is based on two Deep Convolutional Neural Networks (DCNN) stacked in two levels. The first DCNN is used to extract a low-dimensional feature vector using the normalized raw data as input. The second DCNN ingests a list of vectors taken from the former DCNN and estimates the RUL. Model selection was carried out by means of Bayesian optimization using a repeated random subsampling validation approach. The proposed methodology was ranked in the third place of the 2021 PHM Conference Data Challenge.

description: In the complex multi-state system (MSS), reliability analysis is a significant research content, both for equipment design, manufacturing, usage and maintenance. Universal Generating Function (UGF) is an important method in the reliability analysis, which efficiently obtains the system reliability by a fast algebraic procedure. However, when structural relationships between subsystems or components are not clear or without explicit expressions, the UGF method is difficult to use or not applicable at all. Bayesian Network (BN) has a natural advantage in terms of uncertainty inference for the relationship without explicit expressions. For the number of components is extremely large, though, it has the defects of low efficiency. To overcome the respective defects of UGF and BN, a novel reliability analysis method called UGF-BN is proposed for the complex MSS. In the UGF-BN framework, the UGF method is firstly used to analyze the bottom components with a large number. Then probability distributions obtained are taken as the input of BN. Finally, the reliability of the complex MSS is modeled by the BN method. This proposed method improves the computational efficiency, especially for the MSS with the large number of bottom components. Besides, the aircraft reliability-based design optimization based on the UGF-BN method is further studied with budget constraints on mass, power, and cost. Finally, two cases are used to demonstrate and verify the proposed method.

description: The Tukey (or halfspace) depth extends nonparametric methods toward multivariate data. The multivariate analogues of the quantiles are the central regions of the Tukey depth, defined as sets of points in the $d$-dimensional space whose Tukey depth exceeds given thresholds $k$. We address the problem of fast and exact computation of those central regions. First, we analyse an efficient Algorithm A from Liu et al. (2019), and prove that it yields exact results in dimension $d=2$, or for a low threshold $k$ in arbitrary dimension. We provide examples where Algorithm A fails to recover the exact Tukey depth region for $d>2$, and propose a modification that is guaranteed to be exact. We express the problem of computing the exact central region in its dual formulation, and use that viewpoint to demonstrate that further substantial improvements to our algorithm are unlikely. An efficient C++ implementation of our exact algorithm is freely available in the R package TukeyRegion.

description: The primary mode of measuring gender role conflict (GRC) is with the gender role conflict scale (GRCS; O’Neil et al., 1986), a measure of masculine GRC in cisgender males. The current study developed a measure of GRC sensitive to multiple types of GRC (i.e., generalized, feminine, masculine) across a variety of gender-identifying groups (i.e., cisgender female, cisgender male, gender diverse). Exploratory factor analyses were run on a gender diverse sample of 302 emerging adults (M=21.12 years) who completed an experimental measure, the Spectrum Role Conflict Scale- Gender (SRCS-G), along with other measures. I identified a 16-item solution explaining 47.3% of the variance in GRC, with items distributed across subscales measuring feminine GRC, generalized GRC, and masculine GRC. Initial analysis of validity suggests the SRCS-G may serve as a novel alternative to the GRCS in assessing multiple forms of GRC in gender-diverse samples. Multivariate analyses of subscale scores evidence that self-identified females and self-identified gender minorities also experience GRC and that variation in the degree of experience exists by GRC subscale.

description: The halfspace depth is a well studied tool of nonparametric statistics in multivariate spaces, naturally inducing a multivariate generalisation of quantiles. The halfspace depth of a point with respect to a measure is defined as the infimum mass of closed halfspaces that contain the given point. In general, a closed halfspace that attains that infimum does not have to exist. We introduce a flag halfspace - an intermediary between a closed halfspace and its interior. We demonstrate that the halfspace depth can be equivalently formulated also in terms of flag halfspaces, and that there always exists a flag halfspace whose boundary passes through any given point $x$, and has mass exactly equal to the halfspace depth of $x$. Flag halfspaces allow us to derive theoretical results regarding the halfspace depth without the need to differentiate absolutely continuous measures from measures containing atoms, as was frequently done previously. The notion of flag halfspaces is used to state results on the dimensionality of the halfspace median set for random samples. We prove that under mild conditions, the dimension of the sample halfspace median set of $d$-variate data cannot be $d-1$, and that for $d=2$ the sample halfspace median set must be either a two-dimensional convex polygon, or a data point. The latter result guarantees that the computational algorithm for the sample halfspace median form the R package TukeyRegion is exact also in the case when the median set is less-than-full-dimensional in dimension $d=2$.

description: Plasma-boundaries floating in an ionized gas are usually negatively charged. They accumulate electrons more efficiently than ions which leads to the formation of a quasi-stationary electron film at the boundaries. We propose, in a colloquial manner, a physisorption-inspired quantum-kinetic description of the build-up of surface charges at inert plasma boundaries and calculate the electron sticking coefficient and the electron desorption time, which play an important role in determining the quasi-stationary surface charge, and about which little is empirically and theoretically known, from a microscopic model for the electron-wall interaction. In an exploratory calculation we specifically consider a metallic boundary. But thereby we identify quite generally what we believe are the key issues of the electronic microphysics at inert plasma boundaries in the hope to inspire other groups to join us on our journey.

“Verbal Opposition . . . Encouraged by the Powerful”: Transatlantic Literature and the Cultural Cold War

description: The cultural prestige of the United States received a significant boost thanks to the achievements of its artists and intellectuals after World War II. But in 1966, revelations in the New York Times, Ramparts, and elsewhere cast a doubtful light on these accomplishments: Had the CIA secretly funded America’s artistic accomplishments in a so-called “Cultural Cold War”? What does this say about the claims to autonomy made by these writers and artists? Since the 1970s, scholars of the so-called “revisionist school” of art criticism have argued that the history of post-War American modernism needs to be rewritten in the wake of these machinations. This study stems back against these short-sighted views: The revisionists make too much of the fact that this surreptitious support occurred, though rarely if ever what effect it may have had on the content and form of the works by the affected artists. Looking at the writings of the novelists Saul Bellow and Uwe Johnson, the poet Gregory Corso, the cinematic work of director Boots Riley, as well as the critical work of Clement Greenberg and Walter Höllerer, I will argue that these individuals—often supported by private foundations deeply aligned with American foreign policy interests—nevertheless held on to their independence as artists and writers. The revisionist school is wrong to question their autonomy, a fact that would have become clear if its adherents had devoted more attention to formal analysis and a thorough understanding of the complicated world of what’s been called the “liberal consensus” of Western Cold War society. What will emerge is the fact that the revisionist school often simply disagrees with the politics of this consensus and that it casts this political disagreement, misleadingly, in aesthetic terms. Where the revisionists rely often exclusively on archival materials to make their points about the art and literature of the Cultural Cold War, the present study blends archival sources with those sources which matter the most in art and literary history—the works of art themselves.

We consider different search strategies for the Galaxy, for globular clusters and for other galaxies. We show that a 25-day all-sky Galactic survey can find approximately 900 new pulsars, probing the local pulsar population to a deep luminosity limit. For targets of smaller angular size such as globular clusters and galaxies many LOFAR stations can be combined coherently, to make use of the full sensitivity. Searches of nearby northern-sky globular clusters can find new low luminosity millisecond pulsars. Giant pulses from Crab-like extragalactic pulsars can be detected out to over a Mpc.

description: Future high-precision flavor experiments may discover a pattern of deviations from the standard model predictions for flavor-changing neutral current processes. One of the interesting questions that can be answered then will be whether the flavor structure of the new physics is related to that of the standard model or not. We analyze this aspect of flavor physics within a specific framework: supersymmetric models where the soft breaking terms are dominated by gauge-mediation but get non-negligible contributions from gravity-mediation. We compare the possible patterns of non-minimally flavor-violating effects that arise if the gravity-mediated contributions are anarchical vs. the case that they are structured by a Froggatt-Nielsen symmetry. We show that combining information on flavor and CP violation from meson mixing and electric dipole moments is indicative for the flavor structure of gravity-mediation.

description: Formed in protoplanetary disks around young stars, giant planets can leave observational features such as spirals and gaps in their natal disks through planet-disk interactions. Although such features can indicate the existence of giant planets, protoplanetary disk signals can overwhelm the innate luminosity of planets. Therefore, in order to image planets that are embedded in disks, it is necessary to remove the contamination from the disks to reveal the planets possibly hiding within their natal environments. We observe and directly model the detected disk in the Keck/NIRC2 vortex coronagraph $L'$-band observations of the single-armed protoplanetary disk around HD 34282. Despite a non-detection of companions for HD 34282, this direct disk modeling improves planet detection sensitivity by up to a factor of 2 in flux ratio and ${\sim}10 M_{\rm Jupiter}$ in mass. This suggests that performing disk modeling can improve directly imaged planet detection limits in systems with visible scattered light disks, and can help to better constrain the occurrence rates of self-luminous planets in these systems.

description: We propose a minimal model for spherical proteins with aeolotopic pair interactions to describe the equilibrium phase behavior of lysozyme. The repulsive screened Coulomb interactions between the particles are taken into account assuming that the net charges are smeared out homogeneously over the spherical protein surfaces. We incorporate attractive surface patches, with the interactions between patches on different spheres modeled by an attractive Yukawa potential. The parameters entering the attractive Yukawa potential part are determined using information on the experimentally accessed gas-liquid-like critical point. The Helmholtz free energy of the fluid and solid phases is calculated using second-order thermodynamic perturbation theory. Our predictions for the solubility curve are in fair agreement with experimental data. In addition, we present new experimental data for the gas-liquid coexistence curves at various salt concentrations and compare these with our model calculations. In agreement with earlier findings, we observe that the strength and the range of the attractive potential part only weakly depend on the salt content.

description: A heuristic greedy algorithm is developed for efficiently tiling spatially dense redshift surveys. In its first application to the Galaxy and Mass Assembly (GAMA) redshift survey we find it rapidly improves the spatial uniformity of our data, and naturally corrects for any spatial bias introduced by the 2dF multi object spectrograph. We make conservative predictions for the final state of the GAMA redshift survey after our final allocation of time, and can be confident that even if worse than typical weather affects our observations, all of our main survey requirements will be met.

description: This work confronts the challenge of research infrastructure evaluation in Social Sciences and Humanities. Globalisation and data use are causing RIs to become more influential in the SSH. The European Union caught these new tendencies in its most recent plans for RIs development, as ESFRI. Brussels policymakers expressed an interest in the development of projects like OPERAS and DARIAH. The following work aims to underline the role of RIs in the SSH field and how it's possible to evaluate these programs. Taking inspiration from the works conducted in STEM infrastructures, we first define what an RI is, and then show the challenges posed by the evaluation of infrastructures in science. Moreover, we present a a viable methodology which could be able to capture the essence of the work conducted in SSH RIs. We end up showing the limits and possible conclusion that this line of research could draw.

Degenerate topological line surface phonons in quasi-1D double helix crystal SnIP

description: Degenerate points/lines in the bulk band structures of crystals have become a staple of the growing number of topological materials. The bulk-boundary correspondence provides a relation between bulk topology and surface states. While line degeneracies of bulk excitations have been extensively characterized, line degeneracies of surface states are not well understood. We show that SnIP, a quasi-one-dimensional van der Waals material with a double helix crystal structure, exhibits topological nodal rings/lines in both the bulk phonon modes and their corresponding surface states. Using a combination of first-principles calculations, symmetry-based indicator theories and Zak phase analysis, we find that two neighbouring bulk nodal rings form doubly degenerate lines in their drumhead-like surface states, which are protected by the combination of time-reversal and glide mirror symmetries $\mathcal{T}\bar{M}_y$. Our results indicate that surface degeneracies can be generically protected by symmetries such as $\mathcal{T}\bar{M}_y$, and phonons provide an ideal platform to explore such degeneracies.

Distribution of Rational Points on Toric Varieties: A Multi-Height Approach
Creators: name: Demirhan, Arda Huseyin
Publisher: name: University of Illinois at Chicago
Year: 2021
Subjects: Uncategorized

description: Manin's conjecture for Fano varieties predicts an asymptotic formula for the number of rational points of bounded height with respect to the anti-canonical height function on a small enough Zariski open set with a dense set of rational points. In the case of toric varieties, Manin's conjecture was verified by Victor Batyrev and Yuri Tschinkel. In this thesis, we will explain a multi-height variant of the Batyrev-Tschinkel theorem proposed by Emmanuel Peyre in his paper "Beyond heights: slopes and distribution of rational points", where one considers working in "height boxes" instead of using a single height function as a way to get rid of accumulating subvarieties. We prove a formula for the number of rational points of bounded height relative to all the generators of the cone of effective divisors for a toric variety over a number field. The main result of my thesis is the first example of a large family of varieties along the lines of Peyre's idea.

description: Infrared echo has proven to be an effective means to discover transient accretion events of supermassive black holes (SMBHs), such as tidal disruption events (TDEs) and changing-look active galactic nuclei (AGNs), in dusty circumnuclear environments. To explore the dusty populations of SMBH transient events, we have constructed a large sample of Mid-infrared Outbursts in Nearby Galaxies (MIRONG) and performed multiwavelength observations. Here we present the results of multiepoch spectroscopic follow-up observations of a subsample of 54 objects spanning a time scale of 4 yr. Emission-line variability was detected in 22 of them with either emergence or enhancement of broad Balmer emission lines in comparison with pre-outburst spectra. Coronal lines, HeIIλ4686 and Bowen line NIIIλ4640 appeared in the spectra of nine,seven and two sources, respectively. These results suggest that MIRONG is a mixed bag of different transient sources. We have tentatively classified them into different subclass according to their spectral evolution and light curves. Two sources have been in a steady high broad Hα flux up to the latest observation and might be turn-on AGNs. Broad lines faded out in the remaining sources, indicating a transient ionizing source ignited by TDE or sporadic gas accretion. Thirty-one sources do not show noticeable spectral change with respect to their pre-outburst spectra. They have a statistically redder MIR color and lower MIR luminosity of the outbursts,which are consistent with heavily obscured events.
