description: Atomically sharp oxide heterostructures exhibit a range of novel physical phenomena that do not occur in the parent bulk compounds. The most prominent example is the appearance of highly conducting and superconducting states at the interface between the band insulators LaAlO3 and SrTiO3. Here we report a new emergent phenomenon at the LaMnO3/SrTiO3 interface in which an antiferromagnetic insulator abruptly transforms into a magnetic state that exhibits unexpected nanoscale superparamagnetic dynamics. Upon increasing the thickness of LaMnO3 above five unit cells, our scanning nanoSQUID-on-tip microscopy shows spontaneous formation of isolated magnetic islands of 10 to 50 nm diameter, which display random moment reversals by thermal activation or in response to an in-plane magnetic field. Our charge reconstruction model of the polar LaMnO3/SrTiO3 heterostructure describes the sharp emergence of thermodynamic phase separation leading to nucleation of metallic ferromagnetic islands in an insulating antiferromagnetic matrix. The model further suggests that the nearby superparamagnetic-ferromagnetic transition can be gate tuned, holding potential for applications in magnetic storage and spintronics.

description: We investigate how a Higgs mechanism could be responsible for the emergence of gravity in extensions of Einstein theory. In this scenario, at high energies, symmetry restoration could "turn off" gravity, with dramatic implications for cosmology and quantum gravity. The sense in which gravity is muted depends on the details of the implementation. In the most extreme case gravity's dynamical degrees of freedom would only be unleashed after the Higgs field acquires a non-trivial vacuum expectation value, with gravity reduced to a topological field theory in the symmetric phase. We might also identify the Higgs and the Brans-Dicke fields in such a way that in the unbroken phase Newton's constant vanishes, decoupling matter and gravity. We discuss the broad implications of these scenarios.

description: Compact Steep Spectrum, Gigahertz Peaked Spectrum and High Frequency Peak (CSS, GPS, HFP) sources are considered to be young radio sources but the details of their duty cycle are not well understood. In some cases they are thought to develop in large radio galaxies, while in other cases their jets may experience intermittent activity or die prematurely and remain confined within the host galaxy. By studying in a systematic way the presence and the properties of any extended emission surrounding these compact sources we can provide firmer constraints on their evolutionary history and on the timescales of activity of the radio source. Remnant emission from previous outbursts is supposed to have very low surface brightness and to be brighter at low frequency. Taking advantage of the unprecedented sensitivity and resolution provided by the Low Frequency Array (LOFAR) we have started a systematic search of new CSS, GPS and HFP sources with extended emission, as well as a more detailed study of some well-known of these sources. Here we present the key points of our search in the LOFAR fields and a more in-depth analysis on the source B2 0258+35, a CSS source surrounded by a pair of large, diffuse radio lobes.

description: We generalise the construction of integrals of motion for quantum superintegrable models and the deformed oscillator algebra approach. This is presented in the context of 1D systems admitting ladder operators satisfying a parabosonic algebra involving reflection operators and more generally $c_λ$ extended oscillator algebras with grading. We apply the construction on two-dimensional $c_λ$ oscillators. We also introduce two new superintegrable Hamiltonians that are the anisotropic Dunkl and the singular Dunkl oscillators. We construct the integrals and using this extended approach of the Daskaloyannis method with grading and we present an algebraic derivation of the energy spectrum of the two models from the finite dimensional unitary representations and show how their spectrum divides into different sectors and relates to the physical spectrum.

The politics of identity: the roots of radicalization and home-grown terrorism amongst second and third generation immigrants in Europe
Creators: name: Holtgraves, Lindsey
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: Jihadi terrorism in Europe is a growing and ever-changing threat. Radicals embracing a militant brand of Islam were once an external threat, planning missions abroad before traveling to their Western targets. Jihadi terrorism has since evolved into an internal threat with the emergence of loose-knit homegrown terrorist organizations. Second and third generation immigrants have increasingly turned to militant Islam, radicalizing against the very society into which they were born and raised. This phenomenon is complex, stemming from an identity crisis in which second and third generation immigrants do not feel a sense of belonging to their European host societies, nor their ethnic countries of origin. Radical Islam provides a sense of dignity and purpose to youth that oftentimes feel marginalized and discriminated against. There they also find a badly needed sense of identity derived from the greater Islamic community and its fixed value system. Radicalization is a threat to social cohesion in Europe, and requires a nuanced and precise counter-terrorism policy that will increase trust and communication between groups.

description: The isotropic matroid $M[IAS(G)]$ of a graph $G$ is a binary matroid, which is equivalent to the isotropic system introduced by Bouchet. In this paper we discuss four notions of connectivity related to isotropic matroids and isotropic systems. We show that the isotropic system connectivity defined by Bouchet is equivalent to vertical connectivity of $M[IAS(G)]$, and if $G$ has at least four vertices, then $M[IAS(G)]$ is vertically 5-connected if and only if $G$ is prime (in the sense of Cunningham's split decomposition). We also show that $M[IAS(G)]$ is $3$-connected if and only if $G$ is connected and has neither a pendant vertex nor a pair of twin vertices. Our most interesting theorem is that if $G$ has $n\geq7$ vertices then $M[IAS(G)]$ is not vertically $n$-connected. This abstract-seeming result is equivalent to the more concrete assertion that $G$ is locally equivalent to a graph with a vertex of degree $

description: 71Ga NQR, magnetization and specific heat measurements have been performed on polycrystalline Ge doped FeGa3 samples. A crossover from an insulator to a correlated local moment metal in the low doping regime and the evolution of itinerant ferromagnet upon further doping is found. For the nearly critical concentration at the threshold of ferromagnetic order, xC=0.15, (1/T1T) exhibits a pronounced T4/3 power law over two orders of magnitude in temperature which indicates 3D quantum critical ferromagnetic fluctuations. Furthermore, for the ordered x = 0.2 sample (TC = 6 K) 1/T1T could be fitted well in the frame of Moriya's SCR theory for weakly FM systems with 1/T1T proportional to chi. In contrast to this, the low doping regime nicely displays local moment behavior where 1/T1T proportional to chi2 is valid. For temperature tending to zero the Sommerfeld ratio = (C/T) is enhanced (70 mJ/mole-K2 for x = 0.1) which indicates the formation of heavy 3d-electrons.

description: We develop in detail a graphical tensor product reduction scheme, first described by Antoine and Speiser, for the simple rank 2 Lie algebras so(5) = sp(2), su(3), and g(2). This leads to an efficient practical method to reduce tensor products of irreducible representations into sums of such representations. For this purpose, the 2-dimensional weight diagram of a given representation is placed in a "landscape" of irreducible representations. We provide both the landscapes and the weight diagrams for a large number of representations for the three simple rank 2 Lie algebras. We also apply the algebraic "girdle" method, which is much less efficient for calculations by hand for moderately large representations. Computer code for reducing tensor products, based on the graphical method, has been developed as well and is available from the authors upon request.

description: Previous work has shown that the relation between acceptability ratings and frequencies in speech production is exponential. The present study examines the relation between preference ratings and frequencies of choice with a maximally controlled design, using the same material with two experimental procedures, namely a split-100 rating and a forced-choice task. The phenomenon examined is the choice between SO and OS order in German clauses with canonical and experiencer-object verbs in different contexts. The acceptability of the alternative orders under these conditions was obtained by the split-100 rating task. We assumed that the candidate that appears in speech production is the winner of the competition between SO and OS order based on their acceptability in a given condition. The results of the forced-choice task show that the relation between ratings and choice is not just linear, but can be better approximated by higher-order polynomials: the greater the distance between the acceptability values of the alternative candidates, the stronger the bias for the winner candidate.

description: Density-functional-theory-based electronic structure calculations are made to consider the novel electronic states of Ru-pnictides RuP and RuAs where the intriguing phase transitions and superconductivity under doping of Rh have been reported. We find that there appear nearly degenerate flat bands just at the Fermi level in the high-temperature metallic phase of RuP and RuAs; the flat-band states come mainly from the $4d_{xy}$ orbitals of Ru ions and the Rh doping shifts the Fermi level just above the flat bands. The splitting of the flat bands caused by their electronic instability may then be responsible for the observed phase transition to the nonmagnetic insulating phase at low temperatures. We also find that the band structure calculated for RuSb resembles that of the doped RuP and RuAs, which is consistent with experiment where superconductivity occurs in RuSb without Rh doping.

description: We investigate experimentally and theoretically the interference at avoided crossings which are repeatedly traversed as a consequence of an applied ac field. Our model system is a charge qubit in a serial double quantum dot connected to two leads. Our focus lies on effects caused by simultaneous driving with two different frequencies. We work out how the commensurability of the driving frequencies affects the symmetry of the interference patterns both in real space and in Fourier space. For commensurable frequencies, the symmetry depends sensitively on the relative phase between the two modes, whereas for incommensurable frequencies the symmetry of monochromatic driving is always recovered.
Measuring the psychological drivers of participation in collective action to address violence against women in Mumbai, India

Subjects: subject: Medicine and Health Sciences

description: A growing number of public health interventions involve community members in activism to prevent violence against women (VAW), but the psychological drivers of participation are poorly understood. In this project, we developed a new scale for measuring three proposed drivers of participation in collective action to address VAW in the context of urban informal settlements in Mumbai, India: perceived legitimacy, perceived efficacy, and collective action norms. Using a household survey of over 2,500 men and women, we examined its item, construct, and criterion validity. A valid scale would provide useful insight into modifiable beliefs and attitudes that community mobilisation interventions can address to inspire activism in low-resource contexts.

Dynamics of soliton explosions in passively mode-locked fiber lasers

description: A soliton explosion is an instability whereby a dissipative soliton undergoes a sudden structural collapse, but remarkably returns back to its original shape after a short transient. We recently reported the first experimental observation of this effect in a fiber laser (A. F. J. Runge et al., Optica 2, 36 (2015)). Here, we expand on our initial work, presenting a more detailed experimental and numerical study of the characteristics and dynamics of soliton explosions in passively mode-locked fiber lasers. Specifically, we explore different cavity configurations and gain levels, observing and characterizing explosion events using spectral and temporal real-time single-shot techniques. Our results highlight that the explosion characteristics observed in experiments depend critically on the position in the cavity where the output coupler is located. Furthermore, we find that the frequency at which explosions occur can be controlled by adjusting the pump power. We also identify a new kind of ``partial'' explosion, where strong spectral interference fringes appear on the pulse spectra, but a full collapse is avoided. Finally, we perform numerical simulations based on a realistic iterative cavity map, and obtain results that are in good agreement with experimental measurements. Careful analysis of the simulation results provide strong credence to the interpretation that soliton explosions can be linked to a multi-pulsing instability.

In this paper, we investigate situations where Pfister's theorem may be improved. We show that a real polynomial of degree $d$ in $n$ variables that is positive semidefinite is a sum of $2^n-1$ squares of rational functions if $d\leq 2n-2$. If $n$ is even, or equal to $3$ or $5$, this result also holds for $d=2n$.

Estimations for the error of the approximations are also provided. We then compare the numerical approximation of some test function with its exact fractional derivative. We end with an exemplification of how the presented methods can be used to solve partial fractional differential equations of variable order.

Rethinking Human Rights and Citizenship for Blind People in Zimbabwe: The Struggle for Social Inclusion
Creators: name: Shava, Kudzai
Publisher: name: University of Illinois at Chicago
Year: 2023

description: This study extensively explores blind people’s utilization of their knowledge, beliefs and experiences in formulating activism and advocacy strategies for combatting social exclusion and discrimination in Zimbabwe. Using qualitative methods that involved collecting data through in-depth interviews of 20 blind participants and an autoethnography, the study revealed that blind people were engaged in ongoing activism for social inclusion and human rights which has so far yielded mixed results. Success has been notable in government programs/initiatives but has not yet meaningfully generalized to the private sector and society at large. Failure to generalize is predominantly attributable to deeply-entrenched societal negative attitudes towards blind people, and government’s inaction on effective implementation and enforcement of disability-inclusive policies on equal access to education, employment, health and other services. Despite the setbacks, the study also revealed that the activism efforts of blind people themselves provide a potent empowerment-oriented vehicle through which they as individuals, and their organizations can collectively advocate for inclusive social policy formulation and implementation that may eventually enable their full participation in the Zimbabwean society, and their enjoyment of human rights and equal citizenship. Overall, the findings of the study contribute to the growing body of knowledge on disability activism in Global South settings. This knowledge can be utilized globally to further understand disability activism from an ‘Afrocentric’ perspective, and its impact on the collective and sustainable ‘emancipation’ of not only the visually impaired community, but also other disabled people.
An Endnote to History: Julian Huxley, Soviet Scholars, and UNESCO's History of Mankind, 1945-1967
Creators: name: Porter, Louis H.

Year: 2013

description: This thesis traces the relationship between UNESCO director-general Julian Huxley and the Soviet Union from 1945 to the completion of UNESCO's History of Mankind: Scientific and Cultural Development in the 1960s. I argue that Soviet participation in the UNESCO project was one of several instances of confrontation between Huxley's philosophy for UNESCO, Scientific or Evolutionary Humanism, and Soviet ideology during the late-Stalinist and Khrushchev periods. As Huxley formulated his philosophy for UNESCO in the 1940s, he depicted the Soviet Union as an example of the ideological particularity that his universalist philosophy sought to overcome. The influence of Huxley's philosophy on UNESCO's History of Mankind determined the venture's ideological parameters and excluded Soviet contribution to the main narrative of the work, while the presence of Soviet commentary in the endnotes of the History undermined Huxley's original intention that the project show the universality of humanity's scientific and cultural development.

A Validation of Stability-Based Estimates of North Carolina’s Offshore Wind Resource Using a Nested Boundary Layer Method
Creators: name: Schutt, Megan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Wind profile measurements over the ocean have been historically sparse, making offshore wind resource estimations difficult. This study presents a method for improvement of estimates in coastal North Carolina using a land-based SODAR wind profiler. Thermal influences in the area have been found to complicate the wind climate through atmospheric stability. The COARE algorithm was used to calculate a MOST scaling parameter, quantifying surface stability. Knowledge of upwind conditions aided in estimating the influence of nested internal boundary layers (IBLs) where COARE results were applicable. The layers identified in IBL approximations indicate that (1) stable sound cases retain little evidence of the stable environment over the sound, and that (2) in ocean cases, effects of stability can improve wind speed estimation in stable conditions, but (3) wind shear is underestimated in all cases. These results should improve the estimate of the available wind resource, including wind speed, shear and turbulence.

Transparent opacities: the West Building of the North Carolina Museum of Art
Creators: name: Good, Kristin Hawley
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: This paper critically examines the North Carolina Museum of Art's West Building, designed by Thomas Phifer and Partners. Drawing on the methods of critical museum studies, I argue that the architecture and installation of the West Building work together to create a sacred space, which elevates a discourse of pure aesthetics under the false guise of transparency, while structuring a visitor experience that is directly at odds with the museum's stated democratic mission. I frame my argument in response to statements by the museum, architect, and press, which characterize the building in terms of transparency, openness, and democracy. Scholarship on the history and theory of museums, a comparison with the recent expansion of the Virginia Museum of Fine Arts, and evidence from visitor feedback and staff interviews inform my analysis.

description: The spin-conserving length-scale is a key parameter determining functionalities of a broad range of spintronic devices including magnetic multilayer spin-valves in the commercialized magnetic memories or lateral spin transistors in experimental spin-logic elements. Spatially resolved optical pump-and-probe experiments in the lateral devices allow for the direct measurement of the lengthscale and the time-scale at which spin-information is transferred from the injector to the detector. Using this technique, we demonstrate that in an undoped GaAs/AlGaAs layer spins are detected at distances reaching more than ten microns from the injection point at times as short as nanoseconds after the pump-pulse. The observed unique combination of the long-range and highrate electronic spin-transport requires simultaneous suppression of mechanisms limiting the spin life-time and mobility of carriers. Unlike earlier attempts focusing on elaborate doping, gating, or heterostructures we demonstrate that the bare GaAs/AlGaAs layer intrinsically provides superior spin-transport characteristics whether deposited directly on the substrate or embedded in complex heterostructures.

description: Utilizing the Birkhoff--James orthogonality, we present some characterizations of the norm-parallelism for elements of $\mathbb{B}(\mathscr{H})$ defined on a finite dimensional Hilbert space, elements of a Hilbert $C^*$-module over the $C^*$-algebra of compact operators and elements of an arbitrary $C^*$-algebra. We also consider the characterization of norm parallelism problem for operators on a finite dimensional Hilbert space when the operator norm is replaced by the Schatten $p$-norm. Some applications and generalizations are discussed for certain elements of a Hilbert $C^*$-module.

description: The interplay of the relativistic and correlation effects in the permanent electric dipole moments (PDMs) of the X2Σ+ (ν = 0) electronic ground states of the alkaline earth monoflourides (BeF, MgF, CaF, SrF and BaF) has been studied using a relativistic coupled cluster method (RCCM). The calculations were carried out using double, triple and quadruple zeta basis sets, and with no core orbitals frozen. The results are compared with those of other calculations available in the literature and with experiments. The correlation trends in the PDMs of these molecules are discussed in detail.
The effect of oral contraceptive use on muscle properties across the menstrual cycle
Creators: name: Hudson, Jeffrey D.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: Objective: To investigate the effects of oral contraceptive use on active hamstring muscle stiffness, vertical leg stiffness, and hamstring electromechanical delay (EMD). Hypothesis: Non oral contraceptive pill (Non-OCP) users will have altered muscle properties when hormone levels are greatest resulting in decreased muscle stiffness and increased EMD. Oral contraceptive pill (OCP) users will have no difference in muscle properties. Subjects: 15 physically active females using monophasic oral contraception (OCP; age = 19.87 + 1.13 years, height = 165.40 + 7.96 cm, mass = 61.54 + 13.12 kg) and 15 females not using oral contraception (Non-OCP; age = 20.40 = 1.59 years, height = 169.93 +5.62 cm, mass = 62.75 + 10.61) with a normal menstrual cycle. Design and setting: Controlled laboratory setting. Subjects were tested two times across their menstrual cycle (menses and ovulation). Ovulation was detected using urine based ovulation kits. OCP test sessions were matched to non-OCP sessions using pill counting. Measurements: Active hamstring stiffness, vertical leg stiffness, electromechanical delay. Results: There was no significant effect for group or time, nor a group x time interaction for active hamstring stiffness, vertical leg stiffness, and EMD of the hamstrings. Conclusion: This study does not indicate that taking the oral contraceptive pill would alter muscle properties in manners which are suggested to reduce ACL injury risk.
The Committee to Abolish Hell: Strategic Culture, OODA Loops, and Decision-Making by the U.S. National Security Council During the Bosnian War

description: How are important policy decisions made? There are multiple heuristics that have been employed by political scientists, but few of them make use of contemporary control theory heuristics to analyze decision cycles at the national level. However, the difficulty of applying control theory is that it tends to promote rationalistic models that often do not take into account cultural and emotional factors that may strongly shape the actual decision. To bridge these gaps, this thesis seeks to examine the Observe-Orient-Decide-Act (OODA) loop postulated by John Boyd as a decisionmaking model and integrate it with strategic culture theory, which provides a means of understanding the non-rational influences that shape decisions. The United States National Security Council's decision to deploy ground troops in support of the Dayton Peace Agreement is used as a case study.

description: Over the last several years, homelessness has been the rise in Ireland and across Europe. Populations experiencing long-term homelessness face a higher burden of multi-morbidity at an earlier age than housed populations and have poorer health outcomes. However, this population also has more difficulty accessing appropriate health services. Using a realist evaluation approach, this study will evaluate how funding procedures and health system performance management impact service settings, staff, providers and their ability to make themselves accessible to populations experiencing homelessness.

description: Background: Numerical weather and climate models rely on the use of microphysics schemes to simulate clouds and produce precipitation at convective scales. It is important that we understand how different microphysics schemes perform when simulating high impact weather to inform operational forecasting. Methods: Simulations a heavy rainfall event from 17-20 February 2017 over Botswana were made with the Weather Research and Forecasting (WRF) model using four different microphysics schemes. The schemes used were the Weather Research and Forecasting Single Moment 6-class scheme (WSM6); Weather Research and Forecasting Single Moment 5-class scheme (WSM5); Stony Brook University scheme (SBU-YLIN); and Thompson scheme. WSM5 is considered as the least sophisticated of the four schemes, while Thompson is the most sophisticated. Simulations were initialized and forced by the Global Forecast System (GFS), and configured with a grid spacing of 9km over an outer domain and 3km for a nested inner domain without the convection parameterization. The simulations were produced using the University of Botswana and the Centre for High Performance Computing (CHPC) High Performance Computing (HPC) systems. Results: WSM5 and WSM6 simulations are mostly similar; the presence of graupel in WSM6 did not result in large differences in the rainfall simulations. SBU-YLIN simulated the least amount of rainfall, followed by Thompson. All the schemes captured the north-south rainfall gradient observed on 17 February, but with all simulations rainfall is simulated slightly south of where it was observed. All the schemes overestimated rainfall on 18 February over the central parts of Botswana, and underestimated rainfall on 19 February over most of Botswana. Conclusions: Simulations with different microphysics looked more similar to each other, than to observations. Future studies will test WRF configurations including a single nest over Botswana to determine the best configuration for operational forecasting by the Botswana Department of Meteorological Services.

Anthropogenic Controls on Overwash Deposition: Evidence and Consequences
Creators: name: Rogers, Laura
Publisher: name: University of North Carolina at Chapel Hill Graduate School

Subjects: Geomorphology

description: Accelerated sea-level rise and potential future increases in storminess due to climate change will threaten the vitality of barrier islands by lowering their relative elevation and altering overwash frequency. High-density development may further increase island vulnerability by restricting delivery of overwash to the subaerial island. I analyzed pre- and post-Hurricane Sandy (2012) LiDAR surveys of the New Jersey coast to assess human influence. I compared natural environments to two developed environments (commercial and residential) using shore-perpendicular topographic profiles. The volume of overwash delivered to residential and commercial areas is reduced by 40% and 90%, respectively, of that delivered to the natural environment. I use this analysis and an exploratory barrier island evolution model to assess long-term impacts of anthropogenic structures. Simulations suggest natural barrier islands may persist under a range of likely future sea-level rise scenarios (7–13 mm/yr) whereas developed barrier islands will have a long-term tendency toward drowning.
