description: This dissertation investigates how the development and circulation of technologies of surveillance helped refashion institutional structures, systems of representation, and conceptions of nature and society in the Ottoman Empire and Syria throughout the transition from empire to nation-states. While militarization amplified the capabilities of modern states to discipline human perception through conscription and schooling, the notion of an all-seeing perspective - materialized in the aerial view - was incorporated in the apparatus of state power. The account moves between sites across the imperial territory and as the French mandate replaced Ottoman rule in Syria. These include ventures to propagate the map as an instrument of argumentation and discovery in the capital Istanbul, attempts by Jesuit geographers and earth scientists at inculcating new forms of sight upon the public in Beirut and the Beqaa Valley, the building of post-imperial scientific institutions in Damascus, and the optics of aerial warfare as devised by French strategists and subverted by Arab guerrilla commanders. Environmental representations such as maps and aerial photographs sustained competing social and institutional structures by inculcating upon their targeted audience concrete procedures for disciplining perception, which refashioned the subjectivity, social function, and epistemic virtues of the ideal commander and citizen. In the Middle East, as elsewhere, technologies of surveillance were integrated with existing political and philosophical currents such as Ottomanism, Arabism, and French colonialism, while simultaneously refashioning them from within. The coming of aerial warfare was an integral part of this ongoing process of cultural and technological transformation, which reconfigured political, epistemic, and ethical norms of war and peace.

The Disobedient Isle: Bermudian Aesthetic and Material Culture in the British Atlantic, 1609-1753
Creators: Charuhas, Christina Alexis
Publisher: name: Columbia University
Year: 2015
Subjects: Art

description: This dissertation examines the unique aesthetic and material culture produced in and around the historically misunderstood island of Bermuda from the beginning of its European discovery through the height of its economic prosperity in the mid-eighteenth-century. As a naturally uninhabited island located in the northern Atlantic Ocean, I argue that the first cartographic images of Bermuda alternately pictured it as a virgin utopia and foreboding “Isle of Devils” for captivated European audiences. Following the  settlement in 1609, however, I demonstrate how Bermuda’s own visual culture illustrates islanders’ efforts to challenge these mythologies and develop a local culture predicated on colonial disobedience, economic opportunism, and Atlantic cosmopolitanism. Each chapter of my dissertation thereby examines a separate category of aesthetic objects related to Bermuda’s cultural development, beginning with cartographic maps and continuing to natural history illustrations, portraiture, and woven straw bonnets made as part of a profitable cottage industry.
      Given my alternating my focus on locally and externally produced Bermudian objects, this dissertation participates in post-colonial studies that challenge the privileging of the metropole over colony. Indeed, as participants in a predominately maritime economy, I argue that eighteenth-century Bermudians were deeply connected to communities throughout the British Atlantic and used the objects circulating in this space to craft multiple, locally resonant identities. The broad range of object categories considered in this work also creates new space for examining the lived experiences of
      Bermudian slaves, who are traditionally under-represented in the historical record. As these Creole- and Anglo-Bermudians also went on to live and work in other Caribbean and North American colonies throughout the British Atlantic, I argue that they also disseminate Bermudian experiences abroad and helped integrated islanders’ unique interpretations of British colonial identity into the transatlantic cultural webs linking these communities throughout the long eighteenth-century.

description: Particle charging via the mixing of aerosols with unipolar ions typically results in multiple charges on particles. Particle classification and sizing, based on the electrical mobility, ideally requires all the particles being singly charged to the performance enhancement. In this study, we explored the feasibility of maximizing the singly charged fraction of particles via the control of the Nit product in a unipolar charger. The feasibility was first investigated by modeling unipolar diffusion charging. It was found that the singly charged fraction of monodisperse particles could be maximized by the control of the Nit product. A corona-based unipolar charger was also constructed to study the maximization of the singly charged fraction of monodisperse particles. It was found that a wider range of ion concentration in the charging zone could be obtained by the variation of ion-driving voltage compared to that by changing the corona-discharge current. The maximum singly charged fraction of monodisperse particles in various sizes was characterized when the charger was operated at the flow rates of 1.5 and 3.0 lpm. It was evidenced that the current charger could be conditioned to achieve a higher singly charged fraction of particles than that by bipolar chargers in the particle size range of 20 - 200 nm, particularly in the ultrafine particle size range. The control of Nit product in the charging zone of a unipolar charger offers a simple and effective means to enhance the singly charged fraction of particles in a given size range.

description: In the presence of heteroskedasticity, conventional test statistics based on the ordinary least squares (OLS) estimator lead to incorrect inference results for the linear regression model. Given that heteroskedasticity is common in cross-sectional data, the test statistics based on various forms of heteroskedasticity-consistent covariance matrices (HCCMs) have been developed in the literature. In contrast to the standard linear regression model, heteroskedasticity is a more serious problem for spatial econometric models, generally causing inconsistent extremum estimators of model coefficients. This paper investigates the finite sample properties of the heteroskedasticity-robust generalized method of moments estimator (RGMME) for a spatial econometric model with an unknown form of heteroskedasticity. In particular, it develops various HCCM-type corrections to improve the finite sample properties of the RGMME and the conventional Wald test. The Monte Carlo results indicate that the HCCM-type corrections can produce more accurate results for inference on model parameters and the impact effects estimates in small samples.
Modelling Graph Errors: Towards Robust Graph Signal Processing

description: The first step for any graph signal processing (GSP) procedure is to learn the graph signal representation, i.e., to capture the dependence structure of the data into an adjacency matrix. Indeed, the adjacency matrix is typically not known a priori and has to be learned. However, it is learned with errors. A little attention has been paid to modelling such errors in the adjacency matrix, and studying their effects on GSP methods. However, modelling errors in the adjacency matrix will enable both to study the graph error effects in GSP and to develop robust GSP algorithms. In this paper, we therefore introduce practically justifiable graph error models. We also study, both analytically when possible and numerically, the graph error effect on the performance of GSP methods in different types of problems such as filtering of graph signals and independent component analysis of graph signals (graph decorrelation).

description: We show that postselection offers a nonclassical advantage in metrology. In every parameter-estimation experiment, the final measurement or the postprocessing incurs some cost. Postselection can improve the rate of Fisher information (the average information learned about an unknown parameter from an experimental trial) to cost. This improvement, we show, stems from the negativity of a quasiprobability distribution, a quantum extension of a probability distribution. In a classical theory, in which all observables commute, our quasiprobability distribution can be expressed as real and nonnegative. In a quantum-mechanically noncommuting theory, nonclassicality manifests in negative or nonreal quasiprobabilities. The distribution's nonclassically negative values enable postselected experiments to outperform even postselection-free experiments whose input states and final measurements are optimized: Postselected quantum experiments can yield anomalously large information-cost rates. We prove that this advantage is genuinely nonclassical: no classically commuting theory can describe any quantum experiment that delivers an anomalously large Fisher information. Finally, we outline a preparation-and-postselection procedure that can yield an arbitrarily large Fisher information. Our results establish the nonclassicality of a metrological advantage, leveraging our quasiprobability distribution as a mathematical tool.

description: Various bacterial strains (e.g. strains belonging to the genera Bacillus, Paenibacillus, Serratia and Salmonella) exhibit colonial branching patterns during growth on poor semi-solid substrates. These patterns reflect the bacterial cooperative self-organization. Central part of the cooperation is the collective formation of lubricant on top of the agar which enables the bacteria to swim. Hence it provides the colony means to advance towards the food. One method of modeling the colonial development is via coupled reaction-diffusion equations which describe the time evolution of the bacterial density and the concentrations of the relevant chemical fields. This idea has been pursued by a number of groups. Here we present an additional model which specifically includes an evolution equation for the lubricant excreted by the bacteria. We show that when the diffusion of the fluid is governed by nonlinear diffusion coefficient branching patterns evolves. We study the effect of the rates of emission and decomposition of the lubricant fluid on the observed patterns. The results are compared with experimental observations. We also include fields of chemotactic agents and food chemotaxis and conclude that these features are needed in order to explain the observations.

description: The main focus of this paper is the characterization and exploitation of the asymptotic spectrum of the saddle--point matrix sequences arising from the discretization of optimization problems constrained by elliptic partial differential equations. We uncover the existence of a hidden structure in these matrix sequences, namely, we show that these are indeed an example of Generalized Locally Toeplitz (GLT) sequences. We show that this enables a sharper characterization of the spectral properties of such sequences than the one that is available by using only the fact that we deal with saddle--point matrices. Finally, we exploit it to propose an optimal preconditioner strategy for the GMRES, and Flexible-GMRES methods.

description: Objective: Up to 50% of individuals involved in low-velocity motor vehicle collisions report low back pain (LBP). A major limitation in such cases is the lack of knowledge of injury mechanisms linking the collision characteristics to the pain and pathology associated with LBP reporting. Thus, the objective of this investigation was to characterize the physical circumstances of low-velocity motor vehicle collisions that resulted in claims of LBP. Methods: Eighty-three forensically assessed cases were analyzed to identify specific collision and claimant characteristics. Results: Seventy-seven percent of reviewed cases involved a claim of LBP. Of these LBP claim cases, 70% of cases involved a rear-end collision configuration, and 40% of all cases were low-velocity collisions, with severities ranging between 10 and 12 km/h. The most common pre-existing medical condition was prior LBP or evidence of disc degeneration. Conclusions: The results of this investigation provide knowledge of collision characteristics that can be employed in future studies on the mechanisms of low back injury in low-speed motor vehicle collisions.

description: Nonextreme black hole in a cavity within the framework of the canonical or grand canonical ensemble can approach the extreme limit with a finite temperature measured on a boundary located at a finite proper distance from the horizon. In spite of this finite temperature, it is shown that the one-loop contribution $S_{q\text{ }}$of quantum fields to the thermodynamic entropy due to equilibrium Hawking radiation vanishes in the limit under consideration. The same is true for the finite temperature version of the Bertotti-Robinson spacetime into which a classical Reissner-Nordström black hole turns in the extreme limit. The result $S_{q}=0$ is attributed to the nature of a horizon for the Bertotti-Robinson spacetime.

description: Objective: Crash reports contain precoded structured data fields and a crash narrative that can be a source of rich information not included in the structured data. The narrative can be useful for identifying vulnerable roadway users, such as agricultural workers. However, using the narratives often requires manual reviews that are time consuming and costly. The objective of this research was to develop a simple and relatively inexpensive, semi-automated tool for screening crash narratives and expediting the process of identifying crashes with specific characteristics, such as agricultural crashes. Methods: Crash records for Louisiana from 2010 to 2015 were obtained from the Louisiana Department of Transportation (LaDOTD). Records with narratives were extracted and stratified by vehicle type. The majority of analyses focused on a vehicle type of farm equipment (Type T). Two keyword lists, an inclusion list and an exclusion list, were created based on the published literature, subject-matter experts, and findings from a pilot project. Next, a semi-automated tool was developed in Microsoft Excel to identify agricultural crashes. Lastly, the tool’s performance was assessed using a gold standard set of agricultural narratives identified through manual review. Results: The tool reduced the search space (e.g., number of narratives that need manual review) for narratives requiring manual review from 6.7 to 59.4% depending on the research question. Sensitivity was high, with 96.1% of agricultural crash narratives being correctly classified. Of the gold standard agricultural narratives, 58.3% included an equipment keyword and 72.8% included a farm equipment brand. Conclusion: This article provides information on how crash narratives can supplement structured crash data. It also provides an easy-to-implement method to facilitate incorporating narratives into safety research along with keyword lists for identifying agricultural crashes.

description: One of the most important trends in today’s marketplace is consumers’ increased reliance on smartphones not only as a communication device but also as a central platform for accessing information, entertainment and other consumption activities—the so-called “mobile revolution” (Ackley 2015). While the marketing implications of mobile platforms are receiving emerging attention in the marketing modeling literature (e.g., Danaher et al. 2015; Ghose and Han 2011; Sultan et al. 2009), still very little is known about the consumption psychology of smartphone usage.  The purpose of my dissertation is to address this void by examining what is fundamentally different about the psychology of smartphone use. The dissertation consists of two essays examining two complementary components of mobile consumer behavior. In the first essay I focus on clarifying the particular type of relationship that consumers form with their smartphones. Specifically, I advance the hypothesis that smartphones often fulfill the role of “attachment objects” for consumers. That is, smartphones are now used by many consumers in much the same way as pacifiers or security blankets are used by children—which I refer to as the Adult Pacifier Hypothesis. Consistent with this hypothesis, results from two controlled lab experiments show that relative to a comparable device such as one’s personal computer, engaging with one’s smartphone provides greater comfort as well as faster recovery from a stressful situation, both of which are defining characteristics of attachment objects. A third lab study reveals that, under feelings of stress, people actively seek out and engage with the device over other objects in much the same way that a child would seek out and engage with his or her pacifier. Also consistent with this hypothesis, a fourth study shows that the drive to use one’s smartphone becomes especially pronounced among consumers who have recently quit smoking—that is, consumers who are particularly susceptible to anxiety and stress. In the second essay I document an important consequence of consumers’ increased reliance on their smartphones: its impact on user-generated content. Across three field studies and six controlled lab experiments, I find that smartphone usage drives the creation of content that is more emotional, specifically more positively emotional, and potentially more impactful than content generated on PCs. Overall, these findings provide insight into the psychology of the mobile consumer and its downstream marketing implications.
Accelerated estimation of long-timescale kinetics by combining weighted ensemble simulation with Markov model "microstates" using non-Markovian theory

description: The weighted ensemble (WE) simulation strategy provides unbiased sampling of non-equilibrium processes, such as molecular folding or binding, but the extraction of rate constants relies on characterizing steady state behavior. Unfortunately, WE simulations of sufficiently complex systems will not relax to steady state on observed simulation times. Here we show that a post-simulation clustering of molecular configurations into "microbins" using methods developed in the Markov State Model (MSM) community, can yield unbiased kinetics from WE data before steady-state convergence of the WE simulation itself. Because WE trajectories are directional and not equilibrium-distributed, the history-augmented MSM (haMSM) formulation can be used, which yields the mean first-passage time (MFPT) without bias for arbitrarily small lag times. Accurate kinetics can be obtained while bypassing the often prohibitive convergence requirements of the non-equilibrium weighted ensemble. We validate the method in a simple diffusive process on a 2D random energy landscape, and then analyze atomistic protein folding simulations using WE molecular dynamics. We report significant progress towards the unbiased estimation of protein folding times and pathways, though key challenges remain.

description: This dissertation studies the history of philanthropy in the San Francisco Bay Area between the 1940s to the 2010s through the experiences of the foundation managers, professors, and attorneys, who collectively oversaw the distribution of philanthropic wealth for the region’s donors. This dissertation argues that foundation managers and a range of other non-donor professionals were critical to the formation of organized philanthropy in the San Francisco Bay Area since the 1940s, which in limited but vital ways redistributed wealth to organizations that provided social welfare services. In the austere decades of the late 20th century, however, philanthropic intermediaries created new models of giving that, in appealing to affluent people, narrowed the purpose and reach of foundations, while expanding the ability of donors to set conditions on their giving. In tandem with larger political and economic changes, the disruption of philanthropy in the San Francisco Bay Area—the creation of donor-centric modes of giving that appealed to the norms of high-tech and financial moguls—helped produce a local nonprofit sector more reflective of the interests of wealthy donors rather than those in need.
The thermal and two-particle stress-energy must be ill-defined on the 2-d Misner space chronology horizon

description: We show that an analogue of the (four dimensional) image sum method can be used to reproduce the results, due to Krasnikov, that for the model of a real massless scalar field on the initial globally hyperbolic region IGH of two-dimensional Misner space there exist two-particle and thermal Hadamard states (built on the conformal vacuum) such that the (expectation value of the renormalised) stress-energy tensor in these states vanishes on IGH. However, we shall prove that the conclusions of a general theorem by Kay, Radzikowski and Wald still apply for these states. That is, in any of these states, for any point b on the Cauchy horizon and any neighbourhood N of b, there exists at least one pair of non-null related points (x,x'), with x and x' in the intersection of IGH with N, such that (a suitably differentiated form of) its two-point function is singular. (We prove this by showing that the two-point functions of these states share the same singularities as the conformal vacuum on which they are built.) In other words, the stress-energy tensor in any of these states is necessarily ill-defined on the Cauchy horizon.

description: We show that the critical manifold of a statistical mechanical system in the vicinity of a critical point is locally accessible through correlation functions at that point. A practical numerical method is presented to determine the tangent space and the curvature to the critical manifold with Variational Monte Carlo Renormalization Group. Because of the use of a variational bias potential of the coarse-grained variables, critical slowing down is greatly alleviated in the Monte Carlo simulation. In addition, this method is free of truncation error. We study the isotropic Ising model on square and cubic lattices, the anisotropic Ising model and the tricritical Ising model on square lattices to illustrate the method.

Asymptotic Theory for the Probability Density Functions in Burgers Turbulence

description: A rigorous study is carried out for the randomly forced Burgers equation in the inviscid limit. No closure approximations are made. Instead the probability density functions of velocity and velocity gradient are related to the statistics of quantities defined along the shocks. This method allows one to compute the anomalies, as well as asymptotics for the structure functions and the probability density functions. It is shown that the left tail for the probability density function of the velocity gradient has to decay faster than $|ξ|^{-3}$. A further argument confirms the prediction of E et al., Phys. Rev. Lett. {\bf 78}, 1904 (1997), that it should decay as $|ξ|^{-7/2}$.

An Efficient Solution to Non-Minimal Case Essential Matrix Estimation

description: Finding relative pose between two calibrated images is a fundamental task in computer vision. Given five point correspondences, the classical five-point methods can be used to calculate the essential matrix efficiently. For the case of $N$ ($N > 5$) inlier point correspondences, which is called $N$-point problem, existing methods are either inefficient or prone to local minima. In this paper, we propose a certifiably globally optimal and efficient solver for the $N$-point problem. First we formulate the problem as a quadratically constrained quadratic program (QCQP). Then a certifiably globally optimal solution to this problem is obtained by semidefinite relaxation. This allows us to obtain certifiably globally optimal solutions to the original non-convex QCQPs in polynomial time. The theoretical guarantees of the semidefinite relaxation are also provided, including tightness and local stability. To deal with outliers, we propose a robust $N$-point method using M-estimators. Though global optimality cannot be guaranteed for the overall robust framework, the proposed robust $N$-point method can achieve good performance when the outlier ratio is not high. Extensive experiments on synthetic and real-world datasets demonstrated that our $N$-point method is $2\sim3$ orders of magnitude faster than state-of-the-art methods. Moreover, our robust $N$-point method outperforms state-of-the-art methods in terms of robustness and accuracy.

Simulating quantum computers with probabilistic methods
Creators: name: Van Den Nest, Maarten
Publisher: name: The University of British Columbia
Year: 2016

description: The study of quantum computations that can be simulated efficiently classically is of interest for numerous reasons. From a fundamental point of view, such an investigation sheds light on the intrinsic computational power harnessed in quantum mechanics as compared to classical physics. More practically, understanding which quantum computations do not offer any speed-up over classical computation provides insights in where (not) to look for novel quantum algorithmic primitives. In this talk we discuss novel classical simulation methods that are centered on probabilistic methods ('weak simulation'). We show how these techniques outperform existing methods that rely on the exact computation of measurement probabilities ('strong simulation'). Using weak simulation methods, several new classes of simulatable quantum circuits are generated. For example, we show that various concatenations of matchgate, Toffoli, Clifford, bounded-depth, Fourier transform an! d other circuits are classically simulatable. Finally, we focus on famous quantum algorithms and investigate the origin of their computational power, or their lack thereof.

Unified description of a class of models for Bose-Einstein correlations in multiple particle production processes
Creators: name: Zalewski, Kacer
Publisher: name: arXiv
Year: 2002
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Numerous models have been proposed to describe the Bose-Einstein correlations in multiple particle production processes. In the present paper we describe a generalization, which includes many previous models as special cases and, therefore, can be useful for work of comparison. We apply the powerful methods of eigenfunction expansions and generating functionals, which often make the calculations much shorter than in the original papers.

The Dissociation of Valence and Intensity Using Alliesthesia and Thermal Stimulation

description: Psychological models have proposed that valence, how pleasant or unpleasant a stimulus is perceived, and intensity, the strength with which a stimulus is perceived, constitute two primary dimensions that describe affective experience.  However, the inherent relationship between valence and intensity has limited imaging studies of these models and the neural substrates are poorly understood.  For example, it is not known if the neural representations for each dimension are discrete or shared.  To overcome these limitations, we applied properties of alliesthesia, the phenomenon where the valence of a stimulus is dependent upon the physiological state of the body, using thermal stimuli to the hand in combination with whole-body warming and cooling.  In this way, we were able to manipulate the hedonic aspect of our thermal stimuli independent of their perceived intensity.  Brain regions correlating with stimulus valence included the medial orbitofrontal cortex, subgenual anterior cingulate cortex and amygdala, whereas stimulus intensity was correlated with activity in the insula, thalamus and striatum, among others.  Our results suggest segregated patterns of neural activity underlying perceptions of valence and intensity, consistent with dimensional models of emotion.
The Journey to EOSC… on the road together!

EOSCsecretariat

description: Workshop abstract Are you establishing and integrating EOSC activities within your country? Do you need more support and opportunities to swap experiences on how embark on an EOSC action plan and how to reach out effectively to research communities about EOSC services? EOSC is gathering a huge momentum, and how this new research support network is established at national level is now at a critical stage, aspects of which are ongoing at a variety of implementation levels in some member states. While activities are different in each country, they could benefit from and be supported by alignment and good practice exchange. This workshop initiated by OpenAIRE, EOSC hub, and RDA-Europe will explore, with the support of the recently funded EOSCsecretariat.eu project, two areas of implementing EOSC at national level: Establishing national action plans and working with research groups and libraries to raise awareness about EOSC. In particular the workshop will touch on how to set up national action plans, set priorities especially at governance level, how to establish coordinated commitment from key stakeholders and to develop value added support and commitments for local infrastructure within the EOSC vision. Another aspect will be that of serving local research groups and how to target specific EOSC services to them, which is a challenging part of EOSC implementation. This session will be structured in a way that will showcase regional examples of EOSC implementation and good practice. The breakout sessions will be grouped at a regional level in order to identify common threads. This workshop will also provide a perfect setting to meet and network with national counterparts and help prepare and pave the way to set up EOSC and a better understanding of how EOSC works at the national level.
