description: This paper investigates the average symbol error rate (ASER) performance of a dual-hop hybrid relaying system relying on both radio frequency (RF) and free space optical (FSO) links. Specifically, the RF link is used for supporting mobile communication, while the FSO link is adopted as the backhaul of the cellular infrastructure. Considering non-line-of-sight (NLoS) RF transmissions and a generalized atmospheric turbulence (AT) channel, the associated statistical features constituted of both the exact and the asymptotic moment generating functions (MGF) are derived in closed form. They are then used for calculating the ASER of M-ary phase shift keying (PSK), differentially encoded non-coherent PSK (DPSK) and non-coherent frequency-shift keying (FSK). A range of additional asymptotic expressions are also derived for all the modulation schemes under high signal-to-noise ratios (SNR). It is observed from the asymptotic analysis that the ASERs of all the modulation schemes are dominated by the average SNR of the RF link in the hybrid relaying system using a fixed relay gain, while in the relaying system using a dynamic channel dependent relay gain, the ASERs of all the modulation schemes depend both on the average SNR and on the AT condition of the FSO path. We also find that the fixed-gain relaying strategy achieves twice the diversity order of the channel-dependent relaying strategy albeit at the cost of requiring a high power amplifier (PA) dynamic range at the relay node. Furthermore, by comparing the asymptotic ASERs, we calculate the SNR differences between the different modulation schemes in both the fixed-gain and the channel-dependent relaying system. Finally, simulation results are presented for confirming the accuracy of our expressions and observations.

description: Forty legs from twenty lamb of different sexes and sires (colour stable and labile) were aged using in-bag dry- (BD) and wet-ageing (W) for 21 days. BD resulted in significantly lower moisture content, cook loss, colour (L*, a*, b* and chroma) and % polyunsaturated fatty acids (FAs), higher levels of microbial growth and saturated FAs compared to W. Similar NADH content was observed regardless of sex, sire and ageing. Samples from ram and labile sire had significantly higher pH and saturated FAs and reduced monounsaturated FAs composition compared to those from ewe and stable sire. Lamb from labile sire had significantly higher fat melting point than the stable. Thus, the superior stability of stabile sire was observed only in ram and was not impaired by BD. The sex × sire interaction on oxidative stability demonstrated potential to tailor the quality of dry-aged lamb through altering sex and sire of animals.

description: Die Dissertation beschäftigt sich mit dem folgenden Problem: Sei X ein bekannter stochastischer Prozess und T eine unbekannte von X unabhängige Stoppzeit. Das Ziel ist es, auf Grundlage einer Stichprobe von X zur Zeit T die Verteilung von T zurückzugewinnen. Insbesondere sollen nichtparametrische Schätzer für die Dichte f von T konstruiert werden. Belomestny und Schoenmakers lösten dieses statistische Problem in zwei Artikeln aus 2015 und 2016 für die Fälle, wo X entweder eine Brownsche Bewegung oder ein Lévy-Prozess ist. In der vorliegenden Arbeit werden zunächst ihre Resultate bezüglich der Brownschen Bewegung auf selbstähnliche Prozesse verallgemeinert. Ein besonderer Fokus liegt auf Bessel-Prozessen. Als Folge ergibt sich eine Verallgemeinerung der Resultate aus Belomestny und Schoenmakers (2015) auf die mehrdimensionale Brownsche Bewegung. Dies wird durch das Betrachten der euklidischen Norm einer mehrdimensionalen Brownschen Bewegung erreicht, wodurch das Problem auf den Fall eines Bessel-Prozesses zurückgeführt wird. Dieser Prozess ist eindimensional und kann ähnlich wie der Fall einer eindimensionalen Brownschen Bewegung behandelt werden. In einem zweiten Schritt werden sogenannte Sturm-Liouville-Prozesse betrachtet. Diese Prozesse verallgemeinern den Begriff eines Bessel-Prozesses und entstehen häufig aus Normen von anderen mehrdimensionalen Prozessen. Dadurch eignen sie sich besonders zum Modellieren von Teilchenbewegungen in bestimmten physikalischen Experimenten. Darüber hinaus weisen sie eine zu Lévy-Prozessen ähnliche Struktur auf und können durch die für diesen Fall zur Verfügung stehenden Methoden behandelt werden. Die Arbeit ist im Groben wie folgt gegliedert: In einem vorbereitenden Kapitel wird die sogenannte Mellin-Transformierte eingeführt. Diese bildet das mathematische Hauptwerkzeug für die gesamte Arbeit. Unter Benutzung dieser Transformierten werden Methoden zur Konstruktion von nichtparametrischen Schätzern von f für die verschiedenen zugrunde liegenden Prozesse entwickelt. Anschließend werden die statistischen Eigenschaften dieser Schätzer untersucht. Unter Anderem wird die Konsistenz der zuvor konstruierten Schätzer bewiesen und es werden ihre optimalen Konvergenzraten bestimmt. Des Weiteren wird die asymptotische Normalität des Schätzers im Falle eines Bessel-Prozesses gezeigt. Möglichkeiten zur Konstruktion von adaptiven Schätzern werden kurz erläutert und ihre Leistungsfähigkeiten durch Simulationen im Bessel-Fall verglichen.

description: Motivated by a recent experimental study on the quantum Ising magnet $\text{K}_2\text{Co}(\text{SeO}_3)_2$ that presented spectroscopic evidence of zero-field supersolidity (Chen et al., arXiv:2402.15869), we simulate the excitation spectrum of the corresponding microscopic $XXZ$ model for the compound, using the recently developed excitation ansatz for infinite projected entangled-pair states. We map out the ground state phase diagram and compute the dynamical spin structure factors across a range of magnetic field strengths, focusing especially on the two supersolid phases found near zero and saturation fields. Our simulated excitation spectra for the zero-field supersolid "Y" phase are in excellent agreement with the experimental data - recovering the low-energy branches and integer quantized excited energy levels $ω_n=nJ_{zz}$. Furthermore, we demonstrate the nonlocal multi-spin-flip features for modes at $ω_2$, indicative of their multi-magnon nature. Additionally, we identify characteristics of the high-field supersolid "$Ψ$" phase in the simulated spectra, which should be compared with future experimental results.

description: The transition form factor for electrodisintegration of a two-body bound system is calculated in the Bethe-Salpeter framework. For the initial (bound) and the final (scattering) states, we use our solutions of the Bethe-Salpeter equation in Minkowski space which were first obtained recently. The gauge invariance, which manifests itself in the conservation of the transition electromagnetic current Jq = 0, is studied numerically. It results from a cancellation between the plane wave and the final state interaction contributions. This cancellation takes place only if the initial bound state BS amplitude, the final scattering state and the operator of electromagnetic current are strictly consistent with each other, that is if they are found in the same dynamical framework. A reliable result for the transition form factor can be obtained in this case only.

description: The purpose of this thesis was to investigate the effects of a racially homogeneous fan base on the overall black student-athlete experience; it will serve to fill the holes that currently exist surrounding the interplay between racism and fandom. Just like other students, student athletes are expected to deal with all the demands that come with attending a college or university. However, meeting these expectations becomes extremely difficult to do with limited flexibility and time. Student athletes are operating daily on exhaustive schedules that include classes, practices, training sessions, and film, all of which make it tremendously challenging for them to utilize many of the campus resources offered, like student-oriented counseling and workshops, to aid in their transition (Jordan, 2009). Much of the responsibility then falls on the athletic department to ensure all their student-athletes, but especially student-athletes belonging to marginalized groups, are competing in athletic environments that are welcoming, supportive, and comfortable.       On the official website the NCAA is defined as “a member-led organization dedicated to the well-being and lifelong success of college athletes.” Nowhere in their definition does the NCAA mention wins and losses, revenue generation, or any of the other extraneous pieces that have grown to consume the intercollegiate athletic landscape. The market is constantly expanding, viewership and fandom are at all-time highs. However, amid all the excitement, the foundation of college athletics has begun to deteriorate. This study is a necessary part of the conversation when working towards re-prioritizing the well-being of the student-athlete.

description: A central goal of synthetic biology is to design sophisticated synthetic cellular circuits that can perform complex computations and information processing tasks in response to specific inputs. The tremendous advances in our ability to understand and manipulate cellular information processing networks raises several fundamental physics questions: How do the molecular components of cellular circuits exploit energy consumption to improve information processing? Can one utilize ideas from thermodynamics to improve the design of synthetic cellular circuits and modules? Here, we summarize recent theoretical work addressing these questions. Energy consumption in cellular circuits serves five basic purposes: (1) increasing specificity, (2) manipulating dynamics, (3) reducing variability, (4) amplifying signal, and (5) erasing memory. We demonstrate these ideas using several simple examples and discuss the implications of these theoretical ideas for the emerging field of synthetic biology. We conclude by discussing how it may be possible to overcome these limitations using "post-translational" synthetic biology that exploits reversible protein modification.

description: AI-based bi-input predictive models have been executed to forecast the bulk density, linear and volumetric shrinkages and desiccation cracking of HSDA-treated black cotton soil (BCS) for sustainable subgrade construction purposes. The BCS was characterised and classified as A-7 group soil with high plasticity and poorly graded condition. Sawdust ash was obtained by combusting sawdust and sieving through 2.35 mm aperture sieve. It was further activated by blending it with pre-formulated activator material (a blend of 8 M NaOH solution and NaSiO2 in 1:1 ratio) to derive waste-based HSDA. The HSDA was further used in wt % of 3, 6, 9, and 12 to treat the BCS. The treated samples were compacted in the standard proctor moulds, cured for 24 h and extruded. The desiccation tests were then performed on the prepared specimens by drying them at a temp of 102°C for 30 days and behavioural changes in weight, height, diameter, average crack development, etc., were taken throughout the period. Multiple data sets were collected for the references test, and treated specimens of 3, 6, 9, and 12% wt HSDA of the soil for 30 drying days. XRF and SEM tests were also conducted to determine the pozzolanic strength via the chemical oxide composition, three chemical moduli (TCM) and the microstructural arrangement of the experimental materials and the treated BCS. The XRF tests showed that the experimental materials had less pozzolanic strength, which improved with the treated blends thereby forming stabilised mass of BCS. Also, it showed the silica moduli of the TCM dominated the stabilisation of the soil with waste-based HSDA. SEM tests showed increased formation of ettringite and gels with the addition of the HSDA. The data collected was subjected intelligent models’ prediction using ANN, GP and EPR for the four outcomes; BD, CW, LS and VS of the HSDA-treated BCS. The models’ performance showed that EPR outclassed the other techniques in predicting BD and CW with accuracies of 98.2% and 92.7% and minimal error, while ANN outclassed the other techniques in predicting LS and VS with accuracies of 98.8% and 99.3% and minimal error, respectively.

Veronese's Bathing Women: Susanna, Diana, and Bathsheba

description: In a 200-year period roughly corresponding to the early and late Renaissance in Italy from 1450-1650, paintings of the stories of Susanna and the Elders, Diana and Actaeon, and David and Bathsheba, were popular across artistic expression. This thesis examines the work of Venetian Renaissance painter, Paolo Caliari, known as Veronese, by comparing his depictions of these three subjects with established artistic iconography. Through this context it can be argued that he has used the themes of the vulnerable woman, the gaze of males, and the bath, in order to challenge early modern judgement of Susanna, Diana, and Bathsheba. By embracing ambiguity and ambivalence in his paintings, Veronese has highlighted the deliberate role and responsibility of the male characters, thus absolving the women of culpability in the disastrous consequences following the moments that he has painted. In interrogating these images, this thesis seeks to advance a more nuanced understanding of Veronese’s oeuvre.

description: Improving the thermoelectric efficiency is one of the greatest challenges in materials science. The recent discovery of excellent thermoelectric performance in simple orthorhombic SnSe crystal offers new promise in this prospect [Zhao et al. Nature 508, 373 (2014)]. By calculating the thermoelectric properties of orthorhombic IV-VI compounds GeS,GeSe,SnS,and SnSe based on the first-principles combined with the Boltzmann transport theory, we show that the Seebeck coefficient, electrical conductivity, and thermal conductivity of orthorhombic SnSe are in agreement with the recent experiment. Importantly, GeS,GeSe,and SnS exhibit comparative thermoelectric performance compared to SnSe. Especially, the Seebeck coefficients of GeS,GeSe,and SnS are even larger than that of SnSe under the studied carrier concentration and temperature region. We also use the Cahill's model to estimate the lattice thermal conductivities at the room temperature. The large Seebeck coefficients, high power factors, and low thermal conductivities make these four orthorhombic IV-VI compounds promising candidates for high-efficient thermoelectric materials.

For five models of form factors investigated, we find that the localized integrated direct CP violation varies from -0.0170 to -0.0860 in the ranges of parameters in our model when $0.750

description: In limited data computerized tomography, the 2D or 3D problem can be reduced to a family of 1D problems using the differentiated backprojection (DBP) method. Each 1D problem consists of recovering a compactly supported function $f \in L^2(\mathcal F)$, where $\mathcal F$ is a finite interval, from its partial Hilbert transform data. When the Hilbert transform is measured on a finite interval $\mathcal G$ that only overlaps but does not cover $\mathcal F$ this inversion problem is known to be severely ill-posed [1]. In this paper, we study the reconstruction of $f$ restricted to the overlap region $\mathcal F \cap \mathcal G$. We show that with this restriction and by assuming prior knowledge on the $L^2$ norm or on the variation of $f$, better stability with Hölder continuity (typical for mildly ill-posed problems) can be obtained.

description: Landscape composition not only affects a variety of arthropod-mediated ecosystem services, but also disservices, such as herbivory by insect pests that may have negative effects on crop yield. Yet, little is known about how different habitats influence the dynamics of multiple herbivore species, and ultimately their collective impact on crop production. Using cabbage as a model system, we examined how landscape composition influenced the incidence of three specialist cruciferous pests (aphids, flea beetles, and leaf-feeding Lepidoptera), lepidopteran parasitoids, and crop yield across a gradient of landscape composition in New York, USA. We expected that landscapes with a higher proportion of cropland and lower habitat diversity would lead to an increase in pest pressure of the specialist herbivores and a reduction in crop yield. However, results indicated that neither greater cropland area nor lower landscape diversity influenced pest pressure or yield. Rather, pest pressure and yield were best explained by the presence of non-crop habitats (i.e. meadows) in the landscape. Specifically, cabbage was infested with fewer Lepidoptera in landscapes with a higher proportion of meadows likely resulting from increased parasitism. Conversely, cabbage was infested with more flea beetles and aphids as the proportion of meadows in the landscape increased, suggesting that these pests benefit from non-crop habitats. Furthermore, path analysis confirmed that these landscape-mediated effects on pest populations can have either positive or negative cascading effects on crop yield. Our findings illustrate how different pest species within the same cropping system show contrasting responses to landscape composition with respect to both the direction and spatial scale of the relationship. Such tradeoffs resulting from the complex interaction between multiple-pests, natural enemies, and landscape composition must be considered, if we are to manage landscapes for pest suppression benefits.

description: In this work we introduce a low-energy Hamiltonian for single layer and bilayer black phosphorus that describes the electronic states at the vicinity of the gamma point. The model is based on a recently proposed tight-binding description for electron and hole bands close to the Fermi level. We calculate expressions for the Landau level spectrum as function of magnetic field and in the case of bilayer black phosphorus we investigate the effect of an external bias on the electronic band gap. The results showcase the highly anisotropic character of black phosphorus and in particular for bilayer BP, the presence of bias allows for a field-induced semiconductor-metal transition.

Enumerators in S’gaw Karen; A Compilation and Analysis

description: This thesis presents a compilation of numeral classifiers (which I will call enumerators) in S’gaw Karen, a Tibeto-Burman language in Southeast Asia, and provides a descriptive analysis of some of their syntactic distributions. Cross-linguistic accounts of enumerators often sub-categorize them by semantic function (Greenberg 1972; Aikhenvald 2000; Sneft 2000). This thesis argues that the common sub-categories of measure terms, mensural classifiers, and sortal classifiers also differ in their syntactic distributions in S’gaw Karen. In brief, only measure terms occur without a head noun and only sortal classifiers occur next to the head noun by means of a linker. This latter pattern is unattested in the literature, and the analysis of the morpheme Ɂa1 as linker is novel. Previous accounts present a similar morpheme under varied nomenclature (Jones 1961; Cervo 2011; Olson 2014). Analyzing Ɂa1 as a linker unifies these accounts and provides an explanation for this newly described distribution.

The West and Russia: Does the Way Forward Point North?
Creators: name: Lewis, Richard
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: This thesis proposes two methods by which the West can achieve a peaceful and cooperative outcome in the Arctic. As sea ice continues to recede, the northern reaches of the globe open to increased shipping, military presence, oil and precious mineral extraction, fishing and other opportunities. These opportunities represent potential cooperation or competition between interested parties, to include Russia. Realists argue that conflict is inevitable, but there already exists reason to hope for a more peaceful reality. By suggesting a new perspective on the NATO alliance and what it takes to secure ocean shipping and the vulnerable environment in a collaborative way, this thesis seeks to determine a cooperative path with benefits extending far beyond access rights and lower tensions in the Far North.

The effect of discrete emotions on memory: Investigating the replicability and boundary conditions of the mnemonic advantage for disgust
Creators: name: West, John Thomas
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Research has demonstrated that people are more confident in their ability to remember emotional information. However, such research has almost exclusively defined emotion in terms of valence and arousal. Because discrete emotions also affect memory, with disgusting information being better remembered than frightening information, I sought to determine whether participants are sensitive to the effects of discrete emotion when predicting their memory. Participants were more confident in their memory for emotional (frightening and disgusting) images relative to neutral images. However, because Experiment 1a failed to replicate the mnemonic advantage of disgust, subsequent experiments were concerned with testing the replicability of this effect. The disgust advantage was ultimately replicated in an experiment where participants completed a concurrent secondary task at encoding. These results suggest that the mnemonic advantage for disgust may be more likely to manifest under divided attention, perhaps because the mechanisms which mediate disgust memory are relatively automatic.

description: For a large class of dynamical problems from mathematical physics the skew-selfadjointness of a spatial operator of the form $A=\left(\begin{array}{cc} 0 & -C^{*}\\ C & 0 \end{array}\right)$, where $C:D\left(C\right)\subseteq H_{0}\to H_{1}$ is a closed densely defined linear operator, is a typical property. Guided by the standard example, where $C=\mathrm{grad}=\left(\begin{array}{c} \partial_{1}\\ \vdots\\ \partial_{n} \end{array}\right)$ (and $-C^{*}=\mathrm{div}$, subject to suitable boundary constraints), an abstract class of operators $C=\left(\begin{array}{c} C_{1}\\ \vdots\\ C_{n} \end{array}\right)$ is introduced (hence the title). As a particular application we consider a non-standard coupling mechanism and the incorporation of diffusive boundary conditions both modeled by setting associated with a skew-selfadjoint spatial operator $A$.

Survival and Structure of Dusty Vortices in Protoplanetary Discs

description: We have studied the impact of dust feedback on the survival and structure of vortices in protoplanetary discs using 2-D shearing box simulations with Lagrangian dust particles. We consider dust with a variety of sizes (stopping time $t_s = 10^{-2}Ω^{-1} - 10^{2}Ω^{-1}$, from fully coupled with the gas to the decoupling limit. We find that a vortex is destroyed by dust feedback when the total dust-to-gas mass ratio within the vortex is larger than 30-50%, independent of the dust size. The dust distribution can still be asymmetric in some cases after the vortex has been destroyed. With smaller amounts of dust, a vortex can survive for at least 100 orbits, and the maximum dust surface density within the vortex can be more than 100 times larger than the gas surface density, potentially facilitating planetesimal formation. On the other hand, in these stable vortices, small ($t_s < Ω^{-1}$) and large ($t_s > Ω^{-1}$) dust grains concentrate differently and affect the gas dynamics in different ways. The distribution of large dust is more elongated than that of small dust. Large dust ($t_s > Ω^{-1}$) concentrates in the centre of the vortex and feedback leads to turn-over in vorticity towards the centre, forming a quiescent region within an anticyclonic vortex. Such a turn-over is absent if the vortex is loaded with small grains. We demonstrate that, in protoplanetary discs where both large and small dust grains are present and under the right condition, the concentration of large dust towards the vortex centre can lead to a quiescent centre, repelling the small dust and forming a small dust ring around the vortex centre. Such anticorrelations between small and large dust within vortices may explain the discrepancy between ALMA and near-IR scattered light observations in the asymmetric region of transitional discs.
Prospects for a lattice computation of rare kaon decay amplitudes: $K\toπ\ell^+\ell^-$ decays

description: The rare kaon decays $K\toπ\ell^+\ell^-$ and $K\toπν\barν$ are flavor changing neutral current (FCNC) processes and hence promising channels with which to probe the limits of the standard model and to look for signs of new physics. In this paper we demonstrate the feasibility of lattice calculations of $K\toπ\ell^+\ell^-$ decay amplitudes for which long-distance contributions are very significant. We show that the dominant finite-volume corrections (those decreasing as powers of the volume) are negligibly small and that, in the four-flavor theory, no new ultraviolet divergences appear as the electromagnetic current $J$ and the effective weak Hamiltonian $H_W$ approach each other. In addition, we demonstrate that one can remove the unphysical terms which grow exponentially with the range of the integration over the time separation between $J$ and $H_W$. We will now proceed to exploratory numerical studies with the aim of motivating further experimental measurements of these decays. Our work extends the earlier study by Isidori, Turchetti and Martinelli which focussed largely on the renormalization of ultraviolet divergences. In a companion paper we discuss the evaluation of the long-distance contributions to $K\toπν\barν$ decays; these contributions are expected to be at the level of a few percent for $K^+$ decays.

description: Decision-making processes often involve voting. Human interactions with exogenous entities such as legislations or products can be effectively modeled as two-mode (bipartite) signed networks-where people can either vote positively, negatively, or abstain from voting on the entities. Detecting communities in such networks could help us understand underlying properties: for example ideological camps or consumer preferences. While community detection is an established practice separately for bipartite and signed networks, it remains largely unexplored in the case of bipartite signed networks. In this paper, we systematically evaluate the efficacy of community detection methods on projected bipartite signed networks using a synthetic benchmark and real-world datasets. Our findings reveal that when no communities are present in the data, these methods often recover spurious user communities. When communities are present, the algorithms exhibit promising performance, although their performance is highly susceptible to parameter choice. This indicates that researchers using community detection methods in the context of bipartite signed networks should not take the communities found at face value: it is essential to assess the robustness of parameter choices or perform domain-specific external validation.
