description: The random-cluster model is a unifying framework for studying random graphs, spin systems and electrical networks that plays a fundamental role in designing efficient Markov Chain Monte Carlo (MCMC) sampling algorithms for the classical ferromagnetic Ising and Potts models. In this paper, we study a natural non-local Markov chain known as the Chayes-Machta dynamics for the mean-field case of the random-cluster model, where the underlying graph is the complete graph on $n$ vertices. The random-cluster model is parametrized by an edge probability $p$ and a cluster weight $q$. Our focus is on the critical regime: $p = p_c(q)$ and $q \in (1,2)$, where $p_c(q)$ is the threshold corresponding to the order-disorder phase transition of the model. We show that the mixing time of the Chayes-Machta dynamics is $O(\log n \cdot \log \log n)$ in this parameter regime, which reveals that the dynamics does not undergo an exponential slowdown at criticality, a surprising fact that had been predicted (but not proved) by statistical physicists. This also provides a nearly optimal bound (up to the $\log\log n$ factor) for the mixing time of the mean-field Chayes-Machta dynamics in the only regime of parameters where no non-trivial bound was previously known. Our proof consists of a multi-phased coupling argument that combines several key ingredients, including a new local limit theorem, a precise bound on the maximum of symmetric random walks with varying step sizes, and tailored estimates for critical random graphs. In addition, we derive an improved comparison inequality between the mixing time of the Chayes-Machta dynamics and that of the local Glauber dynamics on general graphs; this results in better mixing time bounds for the local dynamics in the mean-field setting.
THE USE OF FAMILY PLANNING POLICY AND REPRODUCTIVE TECHNOLOGIES AS A CONTINUATION OF ETHNIC VIOLENCE IN POST-CONFLICT STATES
Creators: name: Johnson, Sam
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: Ethnic cleansing and future conflict can only be prevented by a thorough analysis of how the historical legacies of inequity pervade into the modern world and a consideration of how mediums for this violence to be carried out change over time. While the literature surrounding the effect of conflict on fertility has been established across a variety of conflicts, and research has been conducted detailing how expectations of fertility of certain groups have contributed to conflict, little research has been done
to determine how family planning policies have the potential to harm targeted populations during and after conflict. This paper aims to address this gap by analyzing the post-conflict states of Bosnia and
Herzegovina, Myanmar, and Rwanda. This is done utilizing a qualitative approach leveraging human rights legislation as a framework for compliance with related human rights indicators. These indicators
are then mapped onto domestic legislation to determine state compliance with international treaties and to explore how family planning, contraception, and reproductive health are reinforced or disregarded in
practice. This study’s primary findings are that (1) case-study countries have infrastructural difficulties that affect resource allocation for all populations, (2) international and domestic legislation and policy
are often theoretically complementary but realistically disconnected with one another, and (3) data regarding the availability, accessibility, acceptability and quality of contraceptive uptake is absent in
case-study states. These findings highlight the infrastructural limitations of case-study states and the international community at large to assist with policy recommendations. Policymakers are urged to reconsider standard Western approaches of family planning promotion, but also to invest in mechanisms to ensure resources are distributed equally, to advocate for the integration of currently self-segregated communities through outreach and subsidies, and to advocate for continued monitoring of post-conflict states and senior officials to ensure state compliance with human rights ideals.

description: Using a Coulomb gas approach, we compute the generating function of the covariances of power traces for one-cut $β$-ensembles of random matrices in the limit of large matrix size. This formula depends only on the support of the spectral density, and is therefore universal for a large class of models. This allows us to derive a closed-form expression for the limiting covariances of an arbitrary one-cut $β$-ensemble. As particular cases of the main result we consider the classical $β$-Gaussian, $β$-Wishart and $β$-Jacobi ensembles, for which we derive previously available results as well as new ones within a unified simple framework. We also discuss the connections between the problem of trace fluctuations for the Gaussian Unitary Ensemble and the enumeration of planar maps.

description: Approximations based on two-particle irreducible (2PI) effective actions (also known as $Φ$-derivable, Cornwall-Jackiw-Tomboulis or Luttinger-Ward functionals depending on context) have been widely used in condensed matter and non-equilibrium quantum/statistical field theory because this formalism gives a robust, self-consistent, non-perturbative and systematically improvable approach which avoids problems with secular time evolution. The strengths of 2PI approximations are often described in terms of a selective resummation of Feynman diagrams to infinite order. However, the Feynman diagram series is asymptotic and summation is at best a dangerous procedure. Here we show that, at least in the context of a toy model where exact results are available, the true strength of 2PI approximations derives from their self-consistency rather than any resummation. This self-consistency allows truncated 2PI approximations to capture the branch points of physical amplitudes where adjustments of coupling constants can trigger an instability of the vacuum. This, in effect, turns Dyson's argument for the failure of perturbation theory on its head. As a result we find that 2PI approximations perform better than Padé approximation and are competitive with Borel-Padé resummation. Finally, we introduce a hybrid 2PI-Padé method.

description: We explore the sensitivity offered by a global network of cosmic ray detectors to a novel, unobserved phenomena: widely separated simultaneous extended air showers. Existing localized observatories work independently to observe individual showers, offering insight into the source and nature of ultra-high energy cosmic rays. However no current observatory is large enough to provide sensitivity to anticipated processes such as the GZ effect or potential new physics that generate simultaneous air showers separated by hundreds to thousands of kilometers. A global network of consumer electronics (the CRAYFIS experiment), may provide a novel opportunity for observation of such phenomena. Two user scenarios are explored. In the first, with maximal user adoption, we find that statistically significant discoveries of spatially-separated but coincident showers are possible within a couple years. In the second, more practical adoption model with $10^6$ active devices, we find a worldwide CRAYFIS to be sensitive to novel "burst" phenomena where many simultaneous EASs occur at once.

Third-order effect in magnetic small-angle neutron scattering by a spatially inhomogeneous medium

Year: 2014
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: Magnetic small-angle neutron scattering (SANS) is a powerful tool for investigating nonuniform magnetization structures inside magnetic materials. Here, considering a ferromagnetic medium with weakly inhomogeneous uniaxial magnetic anisotropy, saturation magnetization, and exchange stiffness, we derive the second-order (in the amplitude of the inhomogeneities) micromagnetic solutions for the equilibrium magnetization textures and compute the corresponding magnetic SANS cross sections up to the next, third order. We find that in the case of perpendicular scattering (the incident neutron beam is perpendicular to the applied magnetic field) if twice the cross section along the direction orthogonal to both the field and the neutron beam is subtracted from the cross section along the field direction, the result has only a third-order contribution (the lower-order terms are canceled). This difference does not depend on the amplitude of the exchange inhomogeneities and provides a separate gateway for a deeper analysis of the sample's magnetic structure. We derive and analyze analytical expressions for the dependence of this combination on the scattering-vector magnitude for the case of spherical Gaussian inhomogeneities.

description: Despite significant advancements in the field of multi-agent navigation, agents still lack the sophistication and intelligence that humans exhibit in multi-agent settings. In this paper, we propose a framework for learning a human-like general collision avoidance policy for agent-agent interactions in fully decentralized, multi-agent environments. Our approach uses knowledge distillation with reinforcement learning to shape the reward function based on expert policies extracted from human trajectory demonstrations through behavior cloning. We show that agents trained with our approach can take human-like trajectories in collision avoidance and goal-directed steering tasks not provided by the demonstrations, outperforming the experts as well as learning-based agents trained without knowledge distillation.

Assessment of a Novel Systems Thinking Framework for Implementers of Self-Management Digital Health Interventions Targeting Young People With Chronic Health Conditions: A Critical Review Protocol

description: This critical review protocol details the plan for a systematic review study to assess the potential effectiveness of self-management supportive digital health interventions (SMDHIs) for Children and Youth with Special Health Care Needs (CYSHCN) using a novel framework for critical appraisal derived from a companion study evaluating the comparative effectiveness of digital health intervention (DHI) implementation strategies for CYSHCN. Given research evidence on the importance of self-management in pediatric patients with chronic health conditions, I hypothesize SMDHIs for CYSHCN require a different mode of understanding the way such tools function relative to the needs of the population. Specifically, there may be a better way to conceptualize SMDHIs (i.e., a solution-directive approach vs. a structured problem-solving approach) and predict the success of existing DHI studies using the framework, which is complementary to Modi and colleagues' (2012) Pediatric Self-Management Model.

description: Random graph models are used to describe the complex structure of real-world networks in diverse fields of knowledge. Studying their behavior and fitting properties are still critical challenges, that in general, require model specific techniques. An important line of research is to develop generic methods able to fit and select the best model among a collection. Approaches based on spectral density (i.e., distribution of the graph adjacency matrix eigenvalues) are appealing for that purpose: they apply to different random graph models. Also, they can benefit from the theoretical background of random matrix theory. This work investigates the convergence properties of model fitting procedures based on the graph spectral density and the corresponding cumulative distribution function. We also review results on the convergence of the spectral density for the most widely used random graph models. Moreover, we explore through simulations the limits of these graph spectral density convergence results, particularly in the case of the block model, where only partial results have been established.

description: We report on the single phase synthesis and room temperature structural characterization of PbFe0.67W0.33O3 (PFW) multiferroic. The PFW was synthesized by low temperature sintering, Columbite method. Analysis of powder XRD pattern exhibits single phase formation of PFW with no traces of pyrochlore phase. Detailed analysis of room temperature neutron diffraction (ND) reveals cubic phase at room temperature, space group Pm-3m. The ND pattern clearly reveals magnetic Bragg peak at 2theeta = 18.51 (Q = 1.36Å-1). The refinement of magnetic structure reveals G-type antiferromagnetic structure in PFW at room temperature. The dielectric constant and loss tangent decreases with increasing frequency. The room temperature P-E measurements shows a non-linear slim hysteresis, typical nature of relaxor multiferroics, with saturation and remnant polarizations of Ps = 1.50 microC/cm2 and Pr = 0.40 microC/cm2, respectively.

description: Separating environmental effects from those of interspecific interactions on species distributions has always been a central objective of community ecology. Despite years of effort in analysing patterns of species co-occurrences and the developments of sophisticated tools, we are still unable to address this major objective. A key reason is that the wealth of ecological knowledge is not sufficiently harnessed in current statistical models, notably the knowledge on interspecific interactions. Here, we develop ELGRIN, a statistical model that simultaneously combines knowledge on interspecific interactions (i.e., the metanetwork), environmental data and species occurrences to tease apart their relative effects on species distributions. Instead of focusing on single effects of pairwise species interactions, which have little sense in complex communities, ELGRIN contrasts the overall effect of species interactions to that of the environment. Using various simulated and empirical data, we demonstrate the suitability of ELGRIN to address the objectives for various types of interspecific interactions like mutualism, competition and trophic interactions. We then apply the model on vertebrate trophic networks in the European Alps to map the effect of biotic interactions on species distributions.Data on ecological networks are everyday increasing and we believe the time is ripe to mobilize these data to better understand biodiversity patterns. ELGRIN provides this opportunity to unravel how interspecific interactions actually influence species distributions.

description: Tidal dissipation in planetary interiors is one of the key physical mechanisms that drive the evolution of star-planet and planet-moon systems. Tidal dissipation in planets is intrinsically related to their internal structure. In particular, fluid and solid layers behave differently under tidal forcing. Therefore, their respective dissipation reservoirs have to be compared. In this work, we compute separately the contributions of the potential dense rocky/icy core and of the convective fluid envelope of gaseous giant planets, as a function of core size and mass. We demonstrate that in general both mechanisms must be taken into account.

State-of-the-Art Report

Subjects: Science Diplomacy

description: The term science diplomacy has gained increasing attention both within academia and in the political agenda setting in recent years. In some cases, it has turned into a reference label when discussing the interaction between science and international affairs. The S4D4C project (Using Science for/in Diplomacy for Addressing Global Challenges) specifically wants to investigate how this interplay acts out on the European level and how European science diplomacy could be strengthened. Yet, from an analytical point of view, it still remains an open question what exactly the term denotes, how it is defined and conceptualized. Particularly, it seems to be both informed by an academic as well as by a political interests. This could compromise the analytical capacity of science diplomacy as a concept. This "state of the art report" examines these questions and provides a literature overview on the discussion and findings of the debate of EU science diplomacy. In doing that, we distinguish between science diplomacy as a discourse and existing activities and structures that could be potentially considered as science diplomacy but do not need to be.

description: We establish a relation between the Raman response function in the $B_{1g}$ channel and the electronic contribution to the nematic susceptibility within the spin-driven approach to electron nematicity of the iron based superconductors. The spin-driven nematic phase, characterized by the broken $C_4$ symmetry, but unbroken $O(3$) spin-rotational symmetry, is generated by the presence of magnetic fluctuations associated with the striped phase. It occurs as a separate phase between $T_N$ and $T_s$ in systems where the structural and magnetic phase transitions are separated. Detecting the presence of nematic degrees of freedom in iron-based superconductors is a difficult task, since it involves measuring higher order spin correlation functions. We show that the nematic degrees of freedom manifest themselves in the experimentally measurable Raman response function. We calculate the Raman response function in tetragonal phase in the large $N$ limit by considering Aslamazov-Larkin type of diagrams that contain a series of inserted fermionic boxes that resemble the nematic coupling constant of the theory. These diagrams effectively account for collisions between spin fluctuations. By summing an infinite number of such higher order diagrams, we demonstrate that the electronic Raman response function shows a clear maximum at the structural phase transition in the $B_{1g}$ channel. Hence, the Raman response function can be used to probe nematic degrees of freedom.

By coating the film with an electron or hole transfer layer, [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) or 2,2,7,7-tetrakis(N,N-di-p-methoxyphenylamine)-9,9-spirobifluorene (Spiro-OMeTAD) respectively, we observed the charge transfer directly through the fluorescence quenching. One-dimensional diffusion model was applied to obtain long charge diffusion distances in thick films, which is ~1.7 um for electrons and up to ~6.3 um for holes. Short diffusion distance of few hundreds of nanosecond was also observed in thin films. This thickness dependent charge diffusion explained the formerly reported short charge diffusion distance (~100 nm) in films and resolved its confliction to thick working layer (300-500 nm) in real devices. This study presents direct support to the high performance perovskite solar cells and will benefit the devices design.

description: A matching from a finite subset $A$ of an abelian group to another subset $B$ is a bijection $f:A\rightarrow B$ with the property that $a+f(a)$ never lies in $A$. A matching is called acyclic if it is uniquely determined by its multiplicity function. Motivated by a question of E. K. Wakeford on canonical forms for symmetric tensors, the study of matchings and acyclic matchings in abelian groups was initiated by C. K. Fan and J. Losonczy in [16, 26], and was later generalized to the context of vector subspaces in a field extension [13, 1]. We discuss the acyclic matching and weak acyclic matching properties and we provide results on the existence of acyclic matchings in finite cyclic groups. As for field extensions, we completely classify field extensions with the linear acyclic matching property. The analogy between matchings in abelian groups and in field extensions is highlighted throughout the paper and numerous open questions are presented for further inquiry.

description: The purpose of this study is to explore the motivations for starting and maintaining archives dedicated to punk materials. Punk, comprising of a number of artistic, counter-cultural, and social movements all generally expressed through a specific subgenre of rock music, is difficult to define. In fact, most involved in punk seem to interpret it in their own way. By interviewing agents involved in the relatively new phenomenon of punk archives, this research attempts to explore why and how these archives rooted in counter-cultural tendencies exist in such a traditionally institutional settings of archives. While not attempting to define what “punk” or “archives” means, this study intends to open the discussion about an overlooked and oversimplified social movement and its position in the archival field.
Asymptotics for densities of exponential functionals of subordinators

description: In this paper we derive non-classical Tauberian asymptotic at infinity for the tail, the density and the derivatives thereof of a large class of exponential functionals of subordinators. More precisely, we consider the case when the Lévy measure of the subordinator satisfies the well-known and mild condition of positive increase. This is achieved via a convoluted application of the saddle point method to the Mellin transform of these exponential functionals which is given in terms of Bernstein-gamma functions. To apply the saddle point method we improved the Stirling type of asymptotic for Bernstein-gamma functions and the latter is of interest beyond this paper as the Bernstein-gamma functions are applicable in different settings especially through their asymptotic behaviour in the complex plane. As an application we have derived the asymptotic of the density and its derivatives for all exponential functionals of non-decreasing, potentially compound Poisson processes which turns out to be precisely as that of an exponentially distributed random variable. We show further that a large class of densities are even analytic in a cone of the complex plane.
Stochastic approximation of symmetric Nash equilibria in queueing games

description: We suggest a novel stochastic-approximation algorithm to compute a symmetric Nash-equilibrium strategy in a general queueing game with a finite action space. The algorithm involves a single simulation of the queueing process with dynamic updating of the strategy at regeneration times. Under mild assumptions on the utility function and on the regenerative structure of the queueing process, the algorithm converges to a symmetric equilibrium strategy almost surely. This yields a powerful tool that can be used to approximate equilibrium strategies in a broad range of strategic queueing models in which direct analysis is impracticable.

Public Access Computers in Libraries

description: Libraries frequently have free WIFI, public computers, printing, and now are relying on digital libraries to increase collection size and accessibility. They make available digital resources to decrease the digital divide. Adding resources to the management systems that coordinate information across multiple branches in a library, as well as housing identifying information required for library cards, and suddenly it becomes apparent how important digital security and privacy is on behalf of library systems. 
Since policies happen at the system level, it’s difficult for individual librarians to advocate for the recommended settings to be implemented if the administration is not fully supportive of the immediacy of such actions. Utilizing ALA guidelines, CIPA, COPPA, and NC Laws, this thesis project serves as a content analysis of 25 NC County Library systems. Through the content analysis, I make apparent basic actionable procedures libraries could implement to increase transparency alongside enhancing protection procedures.
Oral History as Poetry: Re-embodying the Archives through Creative Means

description: Throughout history, archives have often served to enshrine the political status quo at the expense of marginalized communities and voices. Against this example, oral history archives offer a means for democratizing the historical record by amplifying alternative perspectives. In this master’s paper, I argue that oral history sources are best understood and presented creatively—as a kind of poetry—in order to unlock their sensuous, embodied meanings, as well as to promote access and engagement among the public. I then evaluate three cases of creative re-presentations of oral history sources and discuss how each succeeds in re-embodying history and language. I also explore the role of digital technologies in this context.
