description: As a large-scale instance of dramatic collective behaviour, the 2005 French riots started in a poor suburb of Paris, then spread in all of France, lasting about three weeks. Remarkably, although there were no displacements of rioters, the riot activity did travel. Access to daily national police data has allowed us to explore the dynamics of riot propagation. Here we show that an epidemic-like model, with just a few parameters and a single sociological variable characterizing neighbourhood deprivation, accounts quantitatively for the full spatio-temporal dynamics of the riots. This is the first time that such data-driven modelling involving contagion both within and between cities (through geographic proximity or media) at the scale of a country, and on a daily basis, is performed. Moreover, we give a precise mathematical characterization to the expression "wave of riots", and provide a visualization of the propagation around Paris, exhibiting the wave in a way not described before. The remarkable agreement between model and data demonstrates that geographic proximity played a major role in the propagation, even though information was readily available everywhere through media. Finally, we argue that our approach gives a general framework for the modelling of the dynamics of spontaneous collective uprisings.

description: An indole compound, tert-butyl 6-chloro-3-(4,4,5,5-tetramethyl-1,3,2- dioxaborolan-2-yl)-1H-indole-1-carboxylate, was synthesized by a simple and efficient three-step substitution reaction. The structure of compounds can not be determined without the most common methods, namely, 1H NMR, 13C NMR, IR, MS. The structure of the target compound was determined by the above methods. Besides, the single crystal was obtained by solvent evaporation method, and the crystal structure data were obtained by means of X-ray diffraction and compared with the molecular crystal structure determined by density functional theory (DFT). Frontier molecular orbitals and molecular electrostatic potential energy are crucial in the study of chemical properties.

description: The quantum limit can be easily reached in the Dirac semimetals under the magnetic field, which will lead to some exotic many-body physics due to the high degeneracy of the topological zeroth Landau bands (LBs). By solving the effective Hamiltonian, which is derived by tracing out the high energy degrees of freedom, at the self-consistent mean field level, we have systematically studied the instability of Dirac semimetal under a strong magnetic field. A charge density wave (CDW) phase and a polarized nematic phase formed by "exciton condensation" are predicted as the ground state for the tilted and untilted bands, respectively. Furthermore, we propose that, distinguished from the CDW phase, the polarized nematic phase can be identified in experiments by anisotropic transport and Raman scattering.

description: In this Letter, we report a realistic calculation of the magnetic field profile for the equation of state inside strongly magnetized neutron stars. Unlike previous estimates, which are widely used in the literature, we find that magnetic fields increase relatively slowly with increasing baryon chemical potential (or baryon density) of magnetized matter. More precisely, the increase is polynomial instead of exponential, as previously assumed. Through the analysis of several different realistic models for the microscopic description of stellar matter (including hadronic, hybrid and quark models) combined with general relativistic solutions endowed with a poloidal magnetic field obtained by solving Einstein-Maxwell's field equations in a self-consistent way, we generate a phenomenological fit for the magnetic field distribution in the stellar polar direction to be used as input in microscopic calculations.
Loop corrections to primordial fluctuations from inflationary phase transitions

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We investigate loop corrections to the primordial fluctuations in the single-field inflationary paradigm from spectator fields that experience a smooth transition of their vacuum expectation values. We show that when the phase transition involves a classical evolution effectively driven by a negative mass term from the potential, important corrections to the curvature perturbation can be generated by field perturbations that are frozen outside the horizon by the time of the phase transition, yet the correction to tensor perturbation is naturally suppressed by the spatial derivative couplings between spectator fields and graviton. At one-loop level, the dominant channel for the production of primordial fluctuations comes from a pair-scattering of free spectator fields that decay into the curvature perturbations, and this decay process is only sensitive to field masses comparable to the Hubble scale of inflation.

description: In this paper we present conjoined constraints on several cosmological models from the expansion history $H(z)$ and cosmic growth $fσ_8(z)$. The models we study include the CPL $w_0w_a$ parametrization, the Holographic Dark Energy (HDE) model, the Time varying vacuum ($Λ_t$CDM) model, the Dvali, Gabadadze and Porrati (DGP) and Finsler-Randers (FRDE) models, a power law $f(T)$ model and finally the Hu-Sawicki $f(R)$ model. In all cases we perform a simultaneous fit to the SnIa, CMB, BAO, $H(z)$ and growth data, while also following the conjoined visualization of $H(z)$ and $fσ_8(z)$ as in Linder (2017). Furthermore, we introduce the Figure of Merit (FoM) in the $H(z)-fσ_8(z)$ parameter space as a way to constrain models that jointly fit both probes well. We use both the latest $H(z)$ and $fσ_8(z)$ data, but also LSST-like mocks with $1\%$ measurements and we find that the conjoined method of constraining the expansion history and cosmic growth simultaneously is able not only to place stringent constraints on these parameters but also to provide an easy visual way to discriminate cosmological models. Finally, we confirm the existence of a tension between the growth rate and Planck CMB data and we find that the FoM in the conjoined parameter space of $H(z)-fσ_8(z)$ can be used to discriminate between the $Λ$CDM model and certain classes of modified gravity models, namely the DGP and $f(T)$.

description: We study the effect of constant shifts on the zeros of rational harmomic functions $f(z) = r(z) - \conj{z}$. In particular, we characterize how shifting through the caustics of $f$ changes the number of zeros and their respective orientations. This also yields insight into the nature of the singular zeros of $f$. Our results have applications in gravitational lensing theory, where certain such functions $f$ represent gravitational point-mass lenses, and a constant shift can be interpreted as the position of the light source of the lens.

description: We introduce and analyze graph-associated entanglement cost, a generalization of the entanglement cost of quantum states to multipartite settings. We identify a necessary and sufficient condition for any multipartite entangled state to be constructible when quantum communication between the multiple parties is restricted to a quantum network represented by a tree. The condition for exact state construction is expressed in terms of the Schmidt ranks of the state defined with respect to edges of the tree. We also study approximate state construction and provide a second-order asymptotic analysis.

For example, an equation $[ x_1, y_1] \ldots [ x_k, y_k] = z^n$, where $n \ge 2k$, in a free product $\mathcal{F}$ of groups without nontrivial elements of order $\le n$ implies that $z$ is conjugate to an element of a free factor of $\mathcal{F}$. If a nontrivial commutator in a free group factors into a product of elements which are conjugate to each other then all these elements are distinct.

description: ZrTe$_5$ has been of recent interest as a potential Dirac/Weyl semimetal material. Here, we report the results of experiments performed via in-situ 3D double-axis rotation to extract the full $4π$ solid angular dependence of the transport properties. A clear anomalous Hall effect (AHE) was detected for every sample, with no magnetic ordering observed in the system to the experimental sensitivity of torque magnetometry. Interestingly, the AHE takes large values when the magnetic field is rotated in-plane, with the values vanishing above $\sim 60$ K where the negative longitudinal magnetoresistance (LMR) also disappears. This suggests a close relation in their origins, which we attribute to Berry curvature generated by the Weyl nodes.

description: Critical theoretical intersections between adult insecure attachment and personality disorders (PDs) suggest that they may overlap, but a lack of empirical analysis to date has limited further interpretation. The current study used a large sample (N=812) of undergraduates (N=355) and adults receiving psychological treatment (N=457) to test whether a joint hierarchical factor structure of personality pathology and insecure attachment is tenable. Results suggested that attachment and PD indicators load together on latent domains of emotional lability, detachment, and vulnerability, but antagonistic, impulsigenic, and psychosis-spectrum factors do not subsume attachment indicators. This solution was relatively consistent across treatment status but varied across gender, potentially suggesting divergent socialization of interpersonal problems. Although further tests are needed, if attachment and PDs prove to be unitary, combining them has exciting potential for providing an etiologic-developmental substrate to the classification of interpersonal dysfunction.
Revisiting slope influence in turbulent bedload transport: consequences for vertical flow structure and transport rate scaling

description: Gravity-driven turbulent bedload transport has been extensively studied over the past century in regard to its importance for Earth surface processes such as natural riverbed morphological evolution. In the present contribution, the influence of the longitudinal channel inclination angle on gravity-driven turbulent bedload transport is studied in an idealised framework considering steady and uniform flow conditions. From an analytical analysis based on the two-phase continuous equations, it is shown that : (i) the classical slope correction of the critical Shields number is based on an erroneous formulation of the buoyancy force, (ii) the influence of the slope is not restricted to the critical Shields number but affects the whole transport formula and (iii) pressure-driven and gravity-driven turbulent bedload transport are not equivalent from the slope influence standpoint. Analysing further the granular flow driving mechanisms, the longitudinal slope is shown to not only influence the fluid bed shear stress and the resistance of the granular bed, but also to affect the fluid flow inside the granular bed - responsible for the transition from bedload transport to debris flow. The relative influence of these coupled mechanisms allows us to understand the evolution of the vertical structure of the granular flow and to predict the transport rate scaling law as a function of a rescaled Shields number. The theoretical analysis is validated with coupled fluid-discrete element simulations of idealised gravity-driven turbulent bedload transport, performed over a wide range of Shields number values, density ratios and channel inclination angles. In particular, all the data are shown to collapse onto a master curve when considering the sediment transport rate as a function of the proposed rescaled Shields number.
Computation of atomic astrophysical opacities

description: The revision of the standard Los Alamos opacities in the 1980-1990s by a group from the Lawrence Livermore National Laboratory (OPAL) and the Opacity Project (OP) consortium was an early example of collaborative big-data science, leading to reliable data deliverables (atomic databases, monochromatic opacities, mean opacities, and radiative accelerations) widely used since then to solve a variety of important astrophysical problems. Nowadays the precision of the OPAL and OP opacities, and even of new tables (OPLIB) by Los Alamos, is a recurrent topic in a hot debate involving stringent comparisons between theory, laboratory experiments, and solar and stellar observations in sophisticated research fields: the standard solar model (SSM), helio and asteroseismology, non-LTE 3D hydrodynamic photospheric modeling, nuclear reaction rates, solar neutrino observations, computational atomic physics, and plasma experiments. In this context, an unexpected downward revision of the solar photospheric metal abundances in 2005 spoiled a very precise agreement between the helioseismic indicators (the radius of the convection zone boundary, the sound-speed profile, and helium surface abundance) and SSM benchmarks, which could be somehow reestablished with a substantial opacity increase. Recent laboratory measurements of the iron opacity in physical conditions similar to the boundary of the solar convection zone have indeed predicted significant increases (30-400%), although new systematic improvements and comparisons of the computed tables have not yet been able to reproduce them. We give an overview of this controversy, and within the OP approach, discuss some of the theoretical shortcomings that could be impairing a more complete and accurate opacity accounting

description: My dissertation examines the nature of Jean Dubuffet's art with emphasis on the issue of materiality in relation to his figurative style and the abstracted objectivity of his works. Most art historians regard Dubuffet's materiality as an element of his individual style which functions as an alternative to conventional manners of painting. Dubuffet's materiality amounts to more, however, than an unconventional use of unusual material. Throughout his artistic career Dubuffet experimented with new materials; his curiosity in working with the mysteries of coarse, base substances, not associated with the fine arts, was a driving force in his aesthetic process. By focusing on attitudes toward figuration, abstraction, and materiality in Dubuffet's works -painting, and sculpture- my dissertation aims to situate Dubuffet in the postwar era as a Conceptual Artist in Reverse; from matter he aimed to produce ideas. On another note this dissertation explores the degree to which a sense of reality might depend on familiarity with and attitude toward things (thingness) in our worldly environment. In the context of existentialist thought during the postwar period in Europe and the United States, Dubuffet's art and writing present a suitable paradigm for investigating the consequences of the sociopolitical and philosophical conditions contributing to the formation of an alternative figurative art style after WWII. To speak about postwar art from the 1940s to the 1960s in terms of oppositional differences --the rise of abstraction in America contrasted against the simultaneous revival of figuration in Europe-- is to overlook the physical qualities that these works of art shared as objects. My research considers materiality and materialism not only as a philosophical endeavor that was reinvigorated after the Second World War, but also and more so, as the physical baseness prominent in Dubuffet's work. My project provides a new analysis on the critical points of aesthetic connection between the United States and Europe in the postwar era. My work not only contributes to the scholarship on Dubuffet, but also serves to reorient how art historians perceive the rise of seemingly divergent aesthetic styles across the Atlantic. Instead of dwelling on the ruptures between American abstraction and European figuration, this dissertation explores the fruitfulness of the continuities, especially of through the discursive link of materiality.

description: With the rapid development of computing devices and the improved Internet access, our daily lives and business world have been dramatically reshaped. While technology allows companies to attain unprecedented efficiency gains, it also brings about fundamental changes to the competition environment. The goal of this dissertation is to improve our understanding of three major technological developments through the lens of applied economics, econometrics, and machine learning. The first chapter is on the mobile application (app) market. The mobile app market is a fast growing platform which offers consumers millions of applications for smartphones and tablets, but the astronomical number of apps creates a search and discovery problem. I propose an optimal matching for a new advertising strategy, "Cross Promotion (CP)," which allows app developers to locate valuable users while helps app users discover new apps. Distinct from the extant platform literature, which consists mostly of theoretical formulations of platforms, I develop a two-stage model using data from a random matching experiment to examine how users preferences are influenced by apps characteristics. I propose a matching scheme which significantly improves the effectiveness of the CP using the deferred acceptance algorithm. The second chapter is on the issue of cybersecurity. I propose a potential information disclosure policy to alleviate cybersecurity threats. With a large-scale randomized field experiment consisting of 7,919 organizations in the U.S., I show through a random forest-assisted heterogeneous treatment effect analysis that the combination of information notification and publicity significantly reduces large spammers outbound spam volume, which is an indicator of an organizations underlying security condition. The last chapter investigates social media platforms, which is on companies social media strategies under challenging situations. Through a theoretical model, the use of support vector machine, and an empirical analysis using a large Twitter data set, I show the existence of both a negative spillover and a customer encroachment effect after the airline industrys major product-harm crises. In addition, I show that non-focal companies appear to harness two distinct functions of social media-offensive and defensive marketing strategies-to alleviate the negative influence and exploit the unexpected benefit as a result of such incidents.

description: Part and parcel of the PhD project, "W4W2", the draft essay "Useless Collegia" departs from a reading regarding patronage in the Italian Renaissance and social production, wherein Marx makes a brief appearance, and then engages in an argument with Marx about forms of social capital and mediation in relation to revolutionary praxis in the Arts and Humanities. The essay ends abruptly with comments on the necessity of producing totally useless collegia versus nominally useless collegia in relation to the creation of new radical forms of artistic scholarship. The essay is intended to launch an experimental collegium of artists and scholars under the rubric "ART + LAW" (scare quotes, capitalization, and plus sign all telltale) toward exiting the commercium of the art-academic industrial complex and the establishment of a new ecosystem for works in artistic scholarship based on the "no rights" idiom of the W4W2 project.

Substituents were systematically altered in length, substitution pattern, hydrophobic bulk, flexibility, and electronic character, resulting in a variety of ligands with excellent affinity and subtype selectivity for the sigma 2 receptor. It was also found that a dramatic switch in sigma receptor subtype selectivity could be achieved by altering the substitution pattern of the core arene ring in the norbenzomorphan scaffold. These SAR efforts culminated in a sigma 2 receptor selective ligand that was shown to have efficacy in a mouse model of traumatic brain injury (TBI). This was the first example of the effects that sigma 2 receptor modulation has on TBI, thereby making the sigma 2 receptor a unique potential target for novel therapeutics. In a separate project, the total synthesis of (±)-gliocladin C was completed in nine steps and ~15% overall yield. A novel three-step sequence was developed to facilitate the synthesis of a unique diketopiperazine nucleophile that was subsequently reacted with isatin. Lewis acid promoted ionization of the resulting 3-hydroxyoxindole triggered a Friedel-Crafts-like reaction with N-silylated indole to form a key stereogenic quaternary center. A selective reduction of the oxindole amide was achieved using an unusual combination of a Lewis acid and alane. This reaction was optimized to afford the pyrroloindoline framework on a ~1 g scale. The synthesis was completed with a challenging two-step oxidative cleavage of an enamide olefin to unveil the trioxopiperazine moiety of gliocladin C. Two related epipolythiodiketopiperazine alkaloids, (±) gliocladine C and (±) T988C, were also accessed via formal syntheses by diverging from a common synthetic intermediate.

description: How does modern Arabic literature travel within an international literary space increasingly networked for intelligibility across wide areas of the globe? What forms of translatability, and what untranslatables, do Arabic novels activate as they engage twenty-first-century audiences in English translation? This dissertation considers the implications of these questions to be not only practical--a matter of which texts are translated and through which channels they circulate--but also ethical, as the literary structures particular ways for relating across cultural and linguistic borders within an irreducibly heterogeneous contemporary world. Responding to contemporary debates in the field of translation studies over the politics of representation, I challenge the assumption that ethics in translation could be defined as only a matter of how the foreignness of an original text is either conveyed or erased by certain semantic choices. Instead, I draw on theories of affect and embodiment to propose a new mode of understanding both the possibilities and stakes of translating Arabic literature into English today, in which ethics hinges on the capacity of a singular and material otherness, reproduced through the literary, to impinge on the human body, changing it and being changed by it. My argument unfolds over four chapters, each of which presents a different view of this process taking shape in works of modern Arabic fiction. Chapter One interrogates the potentials and risks of affective encounters with the other through a reading of Egyptian author Bahāʼ Ṭāhir's novel Wāḥat al-ghurūb (2007; Sunset Oasis, 2009). Chapter Two attends critically to my own practice in translating Lebanese writer Hilāl Shūmān's novel Līmbū Bayrūt (2013; Limbo Beirut, 2016) into English to theorize the role of the translator's body in the events of language transfer. Chapter Three examines Iraqi author Sinān Anṭūn's English self-translation of his novella Iʿjām (2004; I'jaam: An Iraqi Rhapsody, 2007) to argue that it rewrites the violence of American policies toward Iraq by implicating American readers in structures of corporeal and ontological collapse. Chapter Four interrogates the role of the Abu Dhabi-funded International Prize for Arabic Fiction in creating a new Arabic canon by comparing two novels that won the award--Kuwaiti author Saʿūd al-Sanʿūsī's Sāq al-bāmbū (2013; The Bamboo Stalk, 2015) and Saudi author ʿAbduh Khāl's Tarmī bi-sharar (2009; Throwing Sparks, 2014)--and demonstrating that each elaborates different possibilities for the translatability of modern Arabic literature in an affectively constituted world literary space.

description: We study the compression of data in the case where the useful information is contained in a set rather than a vector, i.e., the ordering of the data points is irrelevant and the number of data points is unknown. Our analysis is based on rate-distortion theory and the theory of finite point processes. We introduce fundamental information-theoretic concepts and quantities for point processes and present general lower and upper bounds on the rate-distortion function. To enable a comparison with the vector setting, we concretize our bounds for point processes of fixed cardinality. In particular, we analyze a fixed number of unordered Gaussian data points and show that we can significantly reduce the required rates compared to the best possible compression strategy for Gaussian vectors. As an example of point processes with variable cardinality, we study the best possible compression of Poisson point processes. For the specific case of a Poisson point process with uniform intensity on the unit square, our lower and upper bounds are separated by only a small gap and thus provide a good characterization of the rate-distortion function.

description: An edge deleted unlabeled subgraph of a graph $G$ is an ecard. A da-ecard specifies the degree of the deleted edge along with the ecard. The degree associated edge reconstruction number of a graph $G$, $\dern(G)$, is the size of the smallest collection of da-ecards of $G$ that uniquely determines $G$. The adversary degree associated edge reconstruction number of a graph $G$, $\adern(G)$, is the minimum number $k$ such that every collection of $k$ da-ecards of $G$ uniquely determines $G$. A strong double broom is the graph on at least 5 vertices obtained from a union of (at least two) internally vertex disjoint paths with same ends $u$ and $v$ by appending leaves at $u$ and $v$. In particular, $B(n,n,mP_{k})$ is the strong double broom with $n$ leaves at both the ends $u$ and $v$ and with $m$ internally vertex disjoint paths of order $k$ joining $u$ and $v$. We show that $\dern$ of strong double brooms is 1 or 2. We also determine $\adern(B(n,n,mP_{k}))$. It is 3 in most of the cases and 1 or 2 for all the remaining cases, except $\adern(B(1,1,2P_{k}))=5$ for $k\geq 4$.

description: We advocate a new semantics, called reduction semantics, for tree generating regular systems and show that it is equivalent to the original semantics. We introduce the concept of weighted tree generating regular systems over strong bimonoids with reduction semantics. We show that (1) weighted tree generating regular systems over the Boolean semiring are equivalent to tree generating regular systems, and (2) weighted tree generating regular systems over semirings are equivalent to weighted tree automata over semirings.

description: The discrepancy between mental health needs and service use has been particularly pronounced in Asian Americans. Given the negative consequences of untreated mental health problems, ways to promote their mental health service use deserve attention. Using Andersen's behavioral model as a conceptual framework, the study explored factors associated with willingness to seek professional mental health service across ethnic-subgroups of Asian Americans. The data were drawn from the 2002 National Latino and Asian American Study. Asian Americans aged 18 over (total n=2,095) were included in the analyses with Chinese (n=600), Vietnamese (n=520), Filipino (n=508), and other Asians (n=467). Logistic regression models were conducted with sets of predictors: (1) predisposing (age, gender, marital status, education, and nativity), (2) mental health needs (diagnosis of psychiatric disorders), (3) enabling variables (health insurance, English proficiency, perceived stigma, social network, and prior exposure of mental health services), and (4) an interaction term between mental health needs and enabling variables. Mental health needs reduced the odds of having willingness to seek service in the sample of Chinese Americans. Vietnamese Americans with no perceived stigma were more likely to be willing to seek professional service. A significant interaction between mental health needs and social network was found in the Vietnamese sample. The linkage between the presence of mental health needs and willingness to seek service in the Vietnamese sample was less likely when they had higher level of social network. Findings highlight similarities and differences between and within subgroups of Asian Americans in the predictors of willingness to seek professional service. The insignificant or negative relationship between mental health needs and willingness may suggest the lack of recognition of mental health problems in Asian Americans. Social network is generally considered as a facilitator for help-seeking behavior, but the combined effect of the presence of mental health needs and higher level of social network may potentially impede Vietnamese Americans from seeking professional service. The distinctive culture of Asian Americans being a collectivistic group needs to be incorporated when developing intervention programs.

description: The ability to monitor respiratory rate is extremely important for medical treatment, healthcare and fitness sectors. In many situations, mobile methods, which allow users to undertake every day activities, are required. However, current monitoring systems can be obtrusive, requiring users to wear respiration belts or nasal probes. Recent advances in thermographic systems have shrunk their size, weight and cost, to the point where it is possible to create smart-phone based respiration rate monitoring devices that are not affected by lighting conditions. However, mobile thermal imaging is challenged in scenes with high thermal dynamic ranges. This challenge is further amplified by general problems such as motion artifacts and low spatial resolution, leading to unreliable breathing signals. In this paper, we propose a novel and robust approach for respiration tracking which compensates for the negative effects of variations in the ambient temperature and motion artifacts and can accurately extract breathing rates in highly dynamic thermal scenes. It has three main contributions. The first is a novel Optimal Quantization technique which adaptively constructs a color mapping of absolute temperature to improve segmentation, classification and tracking. The second is the Thermal Gradient Flow method that computes thermal gradient magnitude maps to enhance accuracy of the nostril region tracking. Finally, we introduce the Thermal Voxel method to increase the reliability of the captured respiration signals compared to the traditional averaging method. We demonstrate the extreme robustness of our system to track the nostril-region and measure the respiratory rate in high dynamic range scenes.
