The Wold isomorphism for cyclostationary sequences
Creators: name: Koski, Timo
name: Hurd, Harry
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2004

description: In 1948 H.Wold introduced an isometric isomorphism between a Hilbert (linear) space formed from the weighted shifts of a numerical sequence and a suitable Hilbert space of values of a second order stochastic sequence. Motivated by a recent resurrection of the idea in the context of cyclostationary sequences and processes, we present the details of the Wold isomorphism between cyclostationary stochastic sequences and cyclostationary numerical sequences. We show how Hilbert-space representations of cyclostationary sequences are interpreted in the case of numerical CS sequences.
Riemannian geometry for the statistical analysis of diffusion tensor data
Creators: name: Fletcher, P. Thomas
name: Joshi, Sarang
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: The tensors produced by diffusion tensor magnetic resonance imaging (DTMRI) represent the covariance in a Brownian motion model of water diffusion. Under this physical interpretation, diffusion tensors are required to be symmetric, positive-definite. However, current approaches to statistical analysis of diffusion tensor data, which treat the tensors as linear entities, do not take this positive-definite constraint into account. This difficulty is due to the fact that the space of diffusion tensors does not form a vector space. In this paper we show that the space of diffusion tensors is a type of curved manifold known as a Riemannian symmetric space. We then develop methods for producing statistics, namely averages and modes of variation, in this space. We show that these statistics preserve natural geometric properties of the tensors, including the constraint that their eigenvalues be positive. The symmetric space formulation also leads to a natural definition for interpolation of diffusion tensors and a new measure of anisotropy. We expect that these methods will be useful in the registration of diffusion tensor images, the production of statistical atlases from diffusion tensor data, and the quantification of the anatomical variability caused by disease. The framework presented in this paper should also be useful in other applications where symmetric, positive-definite tensors arise, such as mechanics and computer vision.

description: Recently, we have derived an effective Cahn-Hilliard equation for the phase separation dynamics of active Brownian particles by performing a weakly non-linear analysis of the effective hydrodynamic equations for density and polarization [Phys. Rev. Lett. 112, 218304 (2014)]. Here we develop and explore this strategy in more detail and show explicitly how to get to such a large-scale, mean-field description starting from the microscopic dynamics. The effective free energy emerging from this approach has the form of a conventional Ginzburg-Landau function. On the coarsest scale, our results thus agree with the mapping of active phase separation onto that of passive fluids with attractive interactions through a global effective free energy (mobility-induced phase transition). Particular attention is paid to the square-gradient term necessary for the dynamics. We finally discuss results from numerical simulations corroborating the analytical results.

description: Descriptions of highly relativistic fermions in a gravitational field in the classical (nonquantum) and quantum approaches are discussed. The results following from the Mathisson-Papapetrou equations for a fast spinning particle in Schwarzschild's and Kerr's background are considered. Numerical estimates for electron, proton and neutrino in the gravitational field of black holes are presented.The general relativistic Dirac equation is analyzed from the point of view it is using for the adequate description of highly relativistic fermions in a gravitational field, in the linear and nonlinear spin approximation. It is necessary to have some corrected Dirac equation for a highly relativistic fermion with strong spin-gravity coupling.

description: Deception is prevalent in human social settings. However, studies into the effect of deception on reinforcement learning algorithms have been limited to simplistic settings, restricting their applicability to complex real-world problems. This paper addresses this by introducing a new mixed competitive-cooperative multi-agent reinforcement learning (MARL) environment inspired by popular role-based deception games such as Werewolf, Avalon, and Among Us. The environment's unique challenge lies in the necessity to cooperate with other agents despite not knowing if they are friend or foe. Furthermore, we introduce a model of deception, which we call Bayesian belief manipulation (BBM) and demonstrate its effectiveness at deceiving other agents in this environment while also increasing the deceiving agent's performance.

description: We present a reinterpretation and extension of the reciprocal theorem for swimmers, extending its application from the motion of a single swimmer in an unbounded domain to the general setting, giving results for both swimmer interactions and general hydrodynamics. We illustrate the method for a squirmer near a planar surface, recovering standard literature results and extending them to a general squirming set, to motion in the presence of a ciliated surface, and expressions for the flow field throughout the domain. Finally, we present exact results for the hydrodynamics in two dimensions which shed light on the near-field behaviour.

Social Capital, Too Much of a Good Thing? American Religious Traditions and Community Crime
Creators: name: Hipp, John R.

Year: 2005

description: Using American religious traditions as measures of bonding and bridging social capital in communities, we empirically test how these different forms of social capital affect crime rates in 3,157 U.S. counties in 2000. Our results suggest that the bonding networks evangelical Protestants promote in communities explain why counties with a greater percentage of residents affiliated with this tradition consistently have higher crime rates. Conversely, our results suggest that the bridging networks mainline Protestants and Catholics foster in communities explain why counties with a greater percentage of residents affiliated with these traditions generally have lower crime rates. This article provides empirical corroboration for recent theoretical discussions that focus on how the social capital groups cultivate in communities need not always benefit communities as a whole.

description: This paper contributes to the international literature examining design of inpatient settings for mental health care. Theoretically, it elaborates the connections between conceptual frameworks from different strands of literature relating to therapeutic landscapes, social control and the social construction of risk. It does so through a discussion of the substantive example of research to evaluate the design of a purpose-built inpatient psychiatric health care facility, opened in 2010 as part of the National Health Service (NHS) in England. Findings are reported from interviews or discussion groups with staff, patients, and their family and friends. This paper demonstrates a strong, and often critical awareness among members of staff and other participants about how responsibilities for risk governance of ‘persons’ are exercised through ‘technical safety’ measures and the implications for therapeutic settings. Our participants often emphasised how responsibility for technical safety was being invested in the physical infrastructure of certain ‘places’ within the hospital where risks are seen to be ‘located’. This illuminates how the spatial dimensions of social constructions of risk are incorporated into understandings about therapeutic landscapes. There were also more subtle implications, partly relating to ‘Panopticist’ theories about how the institution uses technical safety to supervise its own mechanisms, through the observation of staff behaviour as well as patients and visitors. Furthermore, staff seemed to feel that in relying on technical safety measures they were, to a degree, divesting themselves of human responsibility for risks they are required to manage. However, their critical assessment showed their concerns about how this might conflict with a more therapeutic approach and they contemplated ways that they might be able to engage more effectively with patients without the imposition of technical safety measures. These findings advance our thinking about the construction of therapeutic landscapes in theory and in practice.

description: Although there has been a shift toward treatment in the home and the community, in the UK inpatient facilities are still important in modern mental health care. ‘Informal carers’, including family members, often play an essential role, not only in providing care in the community but also in care of patients during periods of hospitalisation. UK National Health Service policies increasingly consider the position of these carers as ‘partners’ in the care process, but relatively little attention has been paid to their position within the hospital settings where treatment is provided for inpatients. This paper contributes to geographical work on carers’ experiences, by reporting how this issue emerged through a study focused on perceptions of a newly built hospital, compared with the inpatient facilities it replaced. We draw on qualitative research findings from discussion groups and interviews with informal carers. The material considered here focused especially on carers’ views of aspects of the hospital environment that were important for wellbeing of carers and the people they look after. The carers’ views were supplemented by relevant material drawn from other interviews from our wider study, which included service users and members of hospital staff. These accounts revealed how informal carers experienced the hospital environment we interpret our findings through a conceptual framework that emphasises carers’ experiences of a ‘journey’ along a ‘caring pathway’ to and through the hospital space. This perspective allows us to make a connection between three bodies of literature. The first relates to phenomenological interpretations of one’s environmental perception, formed as one moves through the world. The second derives from the literature concerning ‘permeability’ of hospital institutions. Bringing these ideas together provides an innovative, dynamic perspective on a third strand of literature from health geography that examines hospitals as ‘therapeutic landscapes’. The analysis helps to explore the extent to which carers in this study were positioned as ‘outsiders’ in the hospital space.

description: This paper reports on research framed by theories of therapeutic landscapes and the ways that the social, physical and symbolic dimensions of landscapes relate to wellbeing and healing. We focus especially on the question of how attributes of therapeutic landscapes are constructed in different ways according to the variable perspectives of individuals and groups. Through an ethnographic case study in a psychiatric hospital in the North of England we explore the perceived significance for wellbeing of ‘smoking spaces’ (where tobacco smoking is practiced in ways that may, or may not be officially sanctioned). We interpret our findings in light of literature on how smoking spaces are linked to the socio-geographical power relations that determine how smoking is organized within the hospital and how this is understood by different groups using the hospital building. We draw on qualitative research findings from discussion groups, observations, and interviews with patients, carers and staff. These focused on their views about the building design and setting of the new psychiatric hospital in relation to their wellbeing, and issues relating to smoking spaces emerged as important for many participants. Creating and managing smoking spaces as a public health measure in psychiatric hospitals is shown to be a controversial issue involving conflicting aims for health and wellbeing of patients and staff. Our findings indicate that although from a physical health perspective, smoking is detrimental, the spaces in which patients and staff smoke have social and psychological significance, providing a forum for the creation of social capital and resistance to institutional control. While the findings relate to one case study setting, the paper illustrates issues of wider relevance and contributes to an international literature concerning the tensions between perceived psychological and psychosocial benefits of smoking vs. physical harm that smoking is likely to cause. We consider the implications for hospital design and the model of care.

description: Objectives: To determine the knowledge, attitudes, and current practice of primary care physiotherapists in recognising and managing clients with metabolic syndrome. Design: Mixed-methods research design comprising an online survey and focus groups. Participants: Australian and English physiotherapists (n = 183) working in a primary care setting responded to the survey. Twelve physiotherapists participated in focus groups. Results: Metabolic syndrome was not on physiotherapists radar. They did not screen for metabolic syndrome nor provide management for it in primary care. Although most physiotherapists had some awareness of metabolic syndrome, they were not knowledgeable. Physiotherapists reported a need to focus on their clients’ presenting condition, and there was uncertainty on whether metabolic syndrome management was within their scope of practice. Despite this, physiotherapists felt they had an important role to play in exercise and physical activity prescription for chronic disease management and were keen to further their knowledge and skills related to metabolic syndrome. Survey responses and focus group data were convergent. Conclusion: Physiotherapists working in primary care settings are well-placed to identify metabolic risk factors in their clients and provide physical activity interventions to enhance management but currently lack knowledge to embed this in clinical practice. Training and resources are required to enable physiotherapists to identify and manage metabolic syndrome within their practice.

Falling fertility rates: new challenges to the European welfare state
Creators: name: Vos, Allison E.

Year: 2009

description: One of the biggest issues currently plaguing many advanced industrialized countries is the persistence of low fertility rates. Decreasing fertility rates threaten economic growth, while government budgets have to accommodate more pension and health services as the number of adults of working age who contribute to older generations’ pensions diminishes. I examine the determinants of fertility levels at the national level of seventeen OECD countries. Specifically, I perform a pooled time series analysis covering the time period 1990-1999. The analysis yields evidence that the types of state policies—active labor market programs, family-friendly policies, and employment protection laws—play a significant role in either helping or hindering fertility levels. I find that Active Labor Market Policies and generous work and family policies encourage higher fertility rates, while the presence of Employment Protection Legislation—rules concerning hiring and firing—hinders the growth of fertility rates.

description: We develop an approach based on stochastic quantum trajectories for an incoherently pumped system of interacting bosons relaxing their energy in a thermal reservoir. Our approach enables the study of the versatile coherence properties of the system. We apply the model to exciton polaritons in a semiconductor microcavity. Our results demonstrate the onset of macroscopic occupation in the lowest-energy mode accompanied by the establishment of both temporal and spatial coherence. We show that temporal coherence exhibits a transition from a thermal to coherent statistics and the spatial coherence reveals off-diagonal long-range order.

description: The free energy cost of confining a star polymer where f flexible polymer chains containing N monomeric units are tethered to a central unit in a slit with two parallel repulsive walls a distance D apart is considered, for good solvent conditions. Also the parallel and perpendicular components of the gyration radius of the star polymer, and the monomer density profile across the slit are obtained. Theoretical descriptions via Flory theory and scaling treatments are outlined, and compared to numerical self-consistent field calculations (applying the Scheutjens-Fleer lattice theory) and to Molecular Dynamics results for a bead-spring model. It is shown that Flory theory and self-consistent field (SCF) theory yield the correct scaling of the parallel linear dimension of the star with N, f and D, but cannot be used for estimating the free energy cost reliably. We demonstrate that the same problem occurs already for the confinement of chains in cylindrical tubes. We also briefly discuss the problem of a free or grafted star polymer interacting with a single wall, and show that the dependence of confining force on the functionality of the star is different for a star confined in a nanoslit and a star interacting with a single wall, which is due to the absence of a symmetry plane in the latter case.

description: To pave the way for the journey from geometry to conformal field theory (CFT), these notes present the background for some basic CFT constructions from Calabi-Yau geometry. Topics include the complex and Kaehler geometry of Calabi-Yau manifolds and their classification in low dimensions. I furthermore discuss CFT constructions for the simplest known examples that are based in Calabi-Yau geometry, namely for the toroidal superconformal field theories and their Z2-orbifolds. En route from geometry to CFT, I offer a discussion of K3 surfaces as the simplest class of Calabi-Yau manifolds where non-linear sigma model constructions bear mysteries to the very day. The elliptic genus in CFT and in geometry is recalled as an instructional piece of evidence in favor of a deep connection between geometry and conformal field theory.

title: 'I am Failure's Success': Francis Picabia and the Enactment of Refusal
Creators: name: Amirkhani, Jordan Haleh
Publisher: name: University of Kent
Year: 2015

description: This dissertation provides a critical re-assessment of the oeuvre of Francis Picabia (1879-1953) and assesses the ways the artist worked to resist the accommodation and domestication of his work. It emphasizes the role of negation and refusal in his painting and poetry, and examines his role as Dadaist and polemicist. This dissertation argues that as artists struggled to render art meaningful and sustainable under the totalizing effects of capitalism and modernity in the first half of the twentieth century, Picabia sought to travesty rather than transcend modernity by enacting an extremely nihilistic form of self-criticism and institutional critique. Picabia’s constant change of style and medium, delight in contradiction, elusive social behavior, extreme egoism, and steadfast commitment to the destabilization of intentionality in his work sought to interrupt the colonizing processes of commodification and to tautologically address the paradoxical and contradictory character of securing meaning in a world without meaning. Divided into five chapters, beginning with Picabia’s affiliation with Puteaux Cubism in Paris in 1911 and ending with a discussion of the final works made before his death in 1953, this dissertation seeks to contextualize major moments of during his career when refusal and negation—even the possible dissolution of his own practice—became the focus of his artistic production. Drawing on the theories of the literary critic Peter Bürger and the Hegelian-Marxist art historian TJ Clark, this study works to come to terms with the strengths, limits, and unresolved ambiguities of Picabia’s willfully antagonistic and conflicted oeuvre and to underscore the critical pressure his work and actions placed on stable narratives of modernism and the conditions that regulate and make meaning available in modern art.

description: Iris/ciliary body tumors can broadly be classified as benign or malignant, cystic or solid, and melanocytic or non-melanocytic. This study aims to provide a systematic review of anterior segment optical coherence tomography (AS-OCT) findings in iris and ciliary body tumors. We conducted a search of published articles related to the use of AS-OCT in iris/ciliary body tumors as of December 2022. Databases that were searched included PubMed, Scopus, and Web of Science. The following search terms in various combinations were used: ‘anterior segment optical coherence tomography,’ ‘ciliary body melanoma,’ ‘ciliary body nevus,’ ‘ciliary body tumor,’ ‘iris cyst,’ ‘iris melanoma,’ ‘iris nevus,’ ‘iris tumor,’ and ‘metastasis.’ A total of 41 studies (10 original articles and 31 case reports) met the inclusion criteria. AS-OCT data pertaining to 545 iris/ciliary body lesions could be retrieved. AS-OCT has proved to be useful as a noninvasive tool for the diagnosis of solid tumors involving the iris/angle with no marked ciliary body involvement, iris pigment epithelial, and iris stromal cysts. To the best of our knowledge, this is the first systematic review in the literature evaluating the utility of AS-OCT in iris/ciliary body tumors.
Ranking Templates for Linear Loops

description: We present a new method for the constraint-based synthesis of termination arguments for linear loop programs based on linear ranking templates. Linear ranking templates are parameterized, well-founded relations such that an assignment to the parameters gives rise to a ranking function. Our approach generalizes existing methods and enables us to use templates for many different ranking functions with affine-linear components. We discuss templates for multiphase, nested, piecewise, parallel, and lexicographic ranking functions. These ranking templates can be combined to form more powerful templates. Because these ranking templates require both strict and non-strict inequalities, we use Motzkin's transposition theorem instead of Farkas' lemma to transform the generated $\exists\forall$-constraint into an $\exists$-constraint.

Data-Assisted Vision-Based Hybrid Control for Robust Stabilization with Obstacle Avoidance via Learning of Perception Maps

description: We study the problem of target stabilization with robust obstacle avoidance in robots and vehicles that have access only to vision-based sensors for the purpose of realtime localization. This problem is particularly challenging due to the topological obstructions induced by the obstacle, which preclude the existence of smooth feedback controllers able to achieve simultaneous stabilization and robust obstacle avoidance. To overcome this issue, we develop a vision-based hybrid controller that switches between two different feedback laws depending on the current position of the vehicle using a hysteresis mechanism and a data-assisted supervisor. The main innovation of the paper is the incorporation of suitable perception maps into the hybrid controller. These maps can be learned from data obtained from cameras in the vehicles and trained via convolutional neural networks (CNN). Under suitable assumptions on this perception map, we establish theoretical guarantees for the trajectories of the vehicle in terms of convergence and obstacle avoidance. Moreover, the proposed vision-based hybrid controller is numerically tested under different scenarios, including noisy data, sensors with failures, and cameras with occlusions.

description: Neutron star Z type sources provide a unique platform in order to understand the structure of accretion disk-corona geometry emitting close to the Eddington luminosity. Using RXTE and NuSTAR satellite data, we performed cross correlation function (CCF) studies in GX 17+2 in order to constrain the size of corona responsible for hard X-rays. From the RXTE data, we found that during horizontal and normal branches, the CCFs show anti-correlated hard (16 - 30 keV) and soft (2 - 5 keV) X-ray delays of the order of a few tens to hundred seconds with a mean correlation coefficient of 0.42$\pm$0.11. Few observations shows correlated lags and on one occasion coincident with radio emission. We also report an anti-correlated hard X-ray delay of 113$\pm$51 s using the NuSTAR data of GX 17+2. Based on RXTE data, it was found that soft and hard X-ray fluxes are varying indicating the changes in the disk-corona structure during delays. We bridle the size of corona using relativistic precession, transition layer and boundary layer models. Assuming the delays to be readjustment time scale of disk-corona structure, height of the corona was estimated to be $\sim$ 17--100 km. Assuming that inner region of the truncated disk is occupied by the corona, we constrain the coronal readjustment velocities (v$_{corona}$=$β$ v$_{disk}$, where v$_{disk}$ is the radial velocity component of the disk) of the order of $β$=0.06-0.12. This study indicates that the observed delays are primarily dependent on the varying coronal readjustment velocities.

description: We report on the experimental observation of spontaneous creation and annihilation of temporal cavity solitons (CSs) in a coherently-driven, macroscopic optical fiber resonator. Specifically, we show that CSs are spontaneously created when the frequency of the cavity driving field is tuned across a resonance, and that they can individually disappear at different stages of the scan. In contrast to previous experiments in monolithic microresonators, we are able to identify these dynamics in real time, thanks to the macroscopic dimensions of our resonator. Our experimental observations are in excellent agreement with numerical simulations. We also discuss the mechanisms responsible for the one-by-one disappearance of CSs.

description: We consider a wireless system with a full-duplex (FD) access point (AP) that transmits to a scheduled user in the downlink (DL) channel, while receiving data from an user in the uplink (UL) channel at the same time on the same frequency. In this system, loopback interference (LI) at the AP and inter user interference between the uplink (UL) user and downlink (DL) user can cause performance degradation. In order to characterize the effects of LI and inter user interference, we derive closed-form expressions for the outage probability and achievable sum rate of the system. In addition an asymptotic analysis that reveals insights into the system behavior and performance degradation is presented. Our results indicate that under certain conditions, FD transmissions yield performance gains over half-duplex (HD) mode of operation.

description: We study the carbon-dope aluminum clusters by using time-of-flight mass spectrum experiments and ab initio calculations. Mass abundance distributions are obtained for anionic aluminum and aluminum-carbon mixed clusters. Besides the well-known magic aluminum clusters such as Al−13 and Al−23, Al7C− cluster is found to be particularly stable among those AlnC− clusters. Density functional calculations are performed to determine the ground state structures of AlnC− clusters. Our results show that the Al7C− is a magic cluster with extremely high stability, which might serve as building block of the cluster-assembled materials.

description: We study the effect of bias voltage on the nuclear spin polarization of a ballistic wire, which contains electrons and nuclei interacting via hyperfine interaction. In equilibrium, the localized nuclear spins are helically polarized due to the electron-mediated Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction. Focusing here on non-equilibrium, we find that an applied bias voltage induces a uniform polarization, from both helically polarized and unpolarized spins available for spin flips. Once a macroscopic uniform polarization in the nuclei is established, the nuclear spin helix rotates with frequency proportional to the uniform polarization. The uniform nuclear spin polarization monotonically increases as a function of both voltage and temperature, reflecting a thermal activation behavior. Our predictions offer specific ways to test experimentally the presence of a nuclear spin helix polarization in semiconducting quantum wires.

description: We consider countable system of harmonic oscillators on the real line with quadratic interaction potential with finite support and local external force (stationary stochastic process) acting only on one fixed particle. In the case of positive definite potential and initial conditions lying in $l_2(\mathbb{Z})$-space the perpesentation of the deviations of the particles from their equilibrium points are found. Precisely, deviation of each particle could be represented as the sum of some stationary process (it is also time limiting process in distribution for that function) and the process which converges to zero as $t\rightarrow+\infty$ with probability one. The time limit for the mean energy of the whole system is found as well.
