description: Realistic relaxed configurations of triaxially strained graphene quantum dots are obtained from unbiased atomistic mechanical simulations. The local electronic structure and quantum transport characteristics of y-junctions based on such dots are studied, revealing that the quasi-uniform pseudomagnetic field induced by strain restricts transport to Landau level- and edge state-assisted resonant tunneling. Valley degeneracy is broken in the presence of an external field, allowing the selective filtering of the valley and chirality of the states assisting in the resonant tunneling. Asymmetric strain conditions can be explored to select the exit channel of the y-junction.

description: We consider the problem of entanglement-assisted one-shot classical communication. In the zero-error regime, entanglement can increase the one-shot zero-error capacity of a family of classical channels following the strategy of Cubitt et al., Phys. Rev. Lett. 104, 230503 (2010). This strategy uses the Kochen-Specker theorem which is applicable only to projective measurements. As such, in the regime of noisy states and/or measurements, this strategy cannot increase the capacity. To accommodate generically noisy situations, we examine the one-shot success probability of sending a fixed number of classical messages. We show that preparation contextuality powers the quantum advantage in this task, increasing the one-shot success probability beyond its classical maximum. Our treatment extends beyond Cubitt et al. and includes, for example, the experimentally implemented protocol of Prevedel et al., Phys. Rev. Lett. 106, 110505 (2011). We then show a mapping between this communication task and a corresponding nonlocal game. This mapping generalizes the connection with pseudotelepathy games previously noted in the zero-error case. Finally, after motivating a constraint we term context-independent guessing, we show that contextuality witnessed by noise-robust noncontextuality inequalities obtained in R. Kunjwal, Quantum 4, 219 (2020), is sufficient for enhancing the one-shot success probability. This provides an operational meaning to these inequalities and the associated hypergraph invariant, the weighted max-predictability, introduced in R. Kunjwal, Quantum 3, 184 (2019). Our results show that the task of entanglement-assisted one-shot classical communication provides a fertile ground to study the interplay of the Kochen-Specker theorem, Spekkens contextuality, and Bell nonlocality.

description: We present a continuous seismic waveform dataset created with the rotated staggered-grid finite-difference simulator HeidimodX (Saenger et al., 2000). The aim of the dataset is to recreate the random nature of ambient seismic noise using numerous synthetic point sources with arbitrary source parameters and locations. Three-component waveforms are recorded at the free surface of a three-dimensional model with two different velocity structures. This dataset can be used to benchmark and test robustness of different methodologies typically applied to ambient noise data.

description: According to the Big Bang Theory as we go back in time the Universe becomes progressively hotter and denser. This leads us to believe that the early Universe was filled with hot plasma of elementary particles. Among many questions concerning this phase of history of the Universe there are questions of existence and fate of magnetic monopoles and primordial black holes. Static solution of Einstein-Yang-Mills system may be used as a toy model for such a black hole. Using methods of field theory we will show that its existence and regularity depend crucially on the presence of fermions around it.

On the Classification between $ψ$-Ontic and $ψ$-Epistemic Ontological Models

description: Harrigan and Spekkens (2010) provided a categorization of quantum ontological models classifying them as $ψ$-ontic or $ψ$-epistemic if the quantum state describes respectively either a physical reality or mere observers' knowledge. Moreover, they claimed that Einstein - who was a supporter of the statistical interpretation of quantum mechanics - endorsed an epistemic view of $ψ$. In this essay we critically assess such a classification and some of its consequences by proposing a two-fold argumentation. Firstly, we show that Harrigan and Spekkens' categorization implicitly assumes that a complete description of a quantum system (its ontic state, $λ$) only concerns single, individual systems instantiating absolute, intrinsic properties. Secondly, we argue that such assumptions conflict with some current interpretations of quantum mechanics, which employ different ontic states as a complete description of quantum systems. In particular, we will show that, since in the statistical interpretation ontic states describe ensembles rather than individuals, such a view cannot be considered psi-epistemic. As a consequence, the authors misinterpreted Einstein's view concerning the nature of the quantum state. Next, we will focus on Relationalist Quantum Mechanics and Perspectival Quantum Mechanics, which in virtue of their relational and perspectival metaphysics employ ontic states lambda dealing with relational properties. We conclude that Harrigan and Spekkens' categorization is too narrow and entails an inadequate classification of the mentioned interpretations of quantum theory. Hence, any satisfactory classification of quantum ontological models ought to take into account the variations of $λ$ across different interpretations of quantum mechanics.

We prove modified scattering for the final state problem and the initial value problem. Moreover, we also consider the failure of scattering for the Schrödinger equation with power-type long-range nonlinearities. These results are extension of the results for NLS on the one dimensional Euclidean space.

Here we report photometry and spectroscopy of the nova. The 'very fast' ($t_{2,r^{\prime}}\sim3.4$ d) and low luminosity ($M_{r^{\prime}}\sim-7.6$) nature of the transient along with the helium in its spectra would indicate that AT 2023prq is a 'faint-and-fast' He/N nova. Additionally, at such a large distance from the centre of M 31, AT 2023prq is a member of the halo nova population.

This range is of particular interest for Cosmic Microwave Background (CMB) studies. For this purpose we have designed and fabricated 100-pixel arrays covering five distinct bands. These wafers have been measured via multiplexing, where a full array is read out using a single pair of lines. We adopted a custom cold black-body installed in front of the detectors and regulated at temperatures between 1 K and 20 K. We will describe in the present paper the main design considerations, the fabrication processes, the testing and the data analysis.

description: Many of the poems in this collection reflect an engagement with an inherited literary tradition of ancient Greek, Latin, and Hebraic mythologies. The first section, entitled "Flint," deals with the ancient text of the Bible and with biblical and religious landscapes. The second section, "'The Seven," based on Aeschylus' The Seven Against Thebes, explores the possibilities of the reinterpretation and elaboration of an ancient story in a contemporary context. While "The Seven" literally refers to the seven gates at Thebes, the number is random, and does in fact represent an infinite number of stories. The penultimate section, "Hoarfrost," explores the voices of women in both contemporary and mythological landscapes. Finally, "Scapes" is a section that confronts landscape in terms of attachment to place. According to traditions of poetics, many of the pieces are written in either blank verse or in some other measured form. All of the poems in Hoarfrost attend the details of image, voice, and music.

CR Structures and Twisting Vacuum Spacetimes with Two Killing Vectors and Cosmological Constant: Type II and More Special

Year: 2013
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Based on the CR formalism of algebraically special spacetimes by Hill, Lewandowski and Nurowski, we derive a nonlinear system of two real ODEs, of which the general solution determines a twisting type II (or more special) vacuum spacetime with two Killing vectors (commuting or not) and at most seven real parameters in addition to the cosmological constant Lambda. To demonstrate a broad range of interesting spacetimes that these ODEs can capture, special solutions of various Petrov types are presented and described as they appear in this approach. They include Kerr-NUT, Kerr and Debney/Demiański's type II, Lun's type II and III (subclasses of Held-Robinson), MacCallum and Siklos' type III (Lambda<0), and the type N solutions (Lambda<>0) we found in an earlier paper, along with a new class of type II solutions as a nontrivial limit of Kerr and Debney's type II solutions. Also, we discuss a situation in which the two ODEs can be reduced to one. However, constructing the general solution still remains an open problem.

description: We compute the spectrum of the category of derived Mackey functors (in the sense of Kaledin) for all finite groups. We find that this space captures precisely the top and bottom layers (i.e. the height infinity and height zero parts) of the spectrum of the equivariant stable homotopy category. Due to this truncation of the chromatic information, we are able to obtain a complete description of the spectrum for all finite groups, despite our incomplete knowledge of the topology of the spectrum of the equivariant stable homotopy category. From a different point of view, we show that the spectrum of derived Mackey functors can be understood as the space obtained from the spectrum of the Burnside ring by "ungluing" closed points. In order to compute the spectrum, we provide a new description of Kaledin's category, as the derived category of an equivariant ring spectrum, which may be of independent interest. In fact, we clarify the relationship between several different categories, establishing symmetric monoidal equivalences and comparisons between the constructions of Kaledin, the spectral Mackey functors of Barwick, the ordinary derived category of Mackey functors, and categories of modules over certain equivariant ring spectra. We also illustrate an interesting feature of the ordinary derived category of Mackey functors that distinguishes it from other equivariant categories relating to the behavior of its geometric fixed points.

Fourier Transform of Rauzy Fractals and Point Spectrum of 1D Pisot Inflation Tilings
Creators: name: Baake, Michael
name: Grimm, Uwe
Publisher: name: Deutsche Mathematiker-Vereinigung
Year: 2020

description: Primitive inflation tilings of the real line with finitely many tiles of natural length and a Pisot--Vijayaraghavan unit as inflation factor are considered. We present an approach to the pure point part of their diffraction spectrum on the basis of a Fourier matrix cocycle in internal space. This cocycle leads to a transfer matrix equation and thus to a closed expression of matrix Riesz product type for the Fourier transforms of the windows for the covering model sets. In general, these windows are complicated Rauzy fractals and thus difficult to handle. Equivalently, this approach permits a construction of the (always continuously representable) eigenfunctions for the translation dynamical system induced by the inflation rule. We review and further develop the underlying theory, and illustrate it with the family of Pisa substitutions, with special emphasis on the classic Tribonacci case.

title: Names as Insults Among Middle School Students
Creators: name: de Veer, Susan M.

description: The following is a study of playful and insulting name-calling among suburban and rural public middle school males and females in grades six through eight in Tidewater, Virginia. Little is known about the effects of name-calling on self-esteem. Students were asked to rate the comfort level of the names they reported their friends called them. They were also asked to list their favorite television programs, films, and music videos to determine what influence, if any, the media has on name-calling. The 135 participating male and female students completed an anonymous survey administered by their teachers during home bell.

The collected names were separated by gender and context, and placed in natural categories: Body Parts, Sexual Orientation, Social Behavior, Intelligence, Physical Features, Sexual Reference, Female Terms, etc. The data were then compared to determine if the context or the gender of the caller affected the way the target felt about a particular name.

Creators: name: Manavalli, Krishna
Publisher: name: Old Dominion University Libraries
Year: 2001

description: U.R. Ananthamurthy is an important Kannada writer who is situated in the navya (modern) literary movement that emerged in Karnataka in the post-independence South Indian context. This modern writer's works provide crucial insights into the postcolonial tensions of tradition-modernity, which figure importantly in modern Kannada literature. They engage with the issues of caste and gender in terms of the conflict between tradition and progress in the modern South Indian cultural discourse. Ananthamurthy's novel Samskara written in the 60's, and his short story “Ghatashraddha,” and “Akkayya,” written later, show how this writer's location within the upper caste discourse impacts his commitment to change and progress. What surfaces as the subliminal, but very central, desire to relegitimize the brahminical structures in his works is linked with the appropriation of the identities and sexualities of the lower caste subjects and woman.

description: Yellow Ribbons is a feature-film screenplay that dramatizes various aspects of the Persian Gulf War. The hero of the story, Lieutenant Jason Hart, a talented but quixotic naval fighter pilot, participates in one of the last allied offensive military actions: the bombing of the retreating Iraqi army. Jake suffers a crisis of conscience in the climactic moment of the bombing and decides that he cannot continue to serve the navy as a fighter pilot. The story then shifts from the Persian Gulf to the United States. There Jake encounters a new set of obstacles as he struggles with his experience in the war. The most important of these obstacles include his crumbling marriage and his quest to tell the truth about the war. Jake is successful in the latter endeavor, but the price he pays is quite high.

description: According to QBism, quantum states, unitary evolutions, and measurement operators are all understood as personal judgments of the agent using the formalism. Meanwhile, quantum measurement outcomes are understood as the personal experiences of the same agent. Wigner's conundrum of the friend, in which two agents ostensibly have different accounts of whether or not there is a measurement outcome, thus poses no paradox for QBism. Indeed the resolution of Wigner's original thought experiment was central to the development of QBist thinking. The focus of this paper concerns two very instructive modifications to Wigner's puzzle: One, a recent no-go theorem by Frauchiger and Renner, and the other a thought experiment by Baumann and Brukner. We show that the paradoxical features emphasized in these works disappear once both friend and Wigner are understood as agents on an equal footing with regard to their individual uses of quantum theory. Wigner's action on his friend then becomes, from the friend's perspective, an action the friend takes on Wigner. Our analysis rests on a kind of quantum Copernican principle: When two agents take actions on each other, each agent has a dual role as a physical system for the other agent. No user of quantum theory is more privileged than any other. In contrast to the sentiment of Wigner's original paper, neither agent should be considered as in "suspended animation." In this light, QBism brings an entirely new perspective to understanding Wigner's friend thought experiments.

description: This novella, set in 1946, explores the needs and wants of Cooley and Edna Godwin, who have been married almost twenty years. The title comes from a popular song of the time about the constancy of love. The story opens and closes with both the husband's and wife's perspectives, but the central body of the work takes on Edna's consciousness as she leaves home, South Norfolk, Virginia, to look for happiness in California. During her travels, she is forced to examine her prejudices, to question her myopic view of the world, and to recognize the nature of true love.

description: We use \Pab\ (1282~nm) observations from the Hubble Space Telescope ($\HST$) G141 grism to study the star-formation and dust attenuation properties of a sample of 29 low-redshift ($z < 0.287$) galaxies in the CANDELS Ly$α$ Emission at Reionization (CLEAR) survey. We first compare the nebular attenuation from $\Pab/\Ha$ with the stellar attenuation inferred from the spectral energy distribution, finding that the galaxies in our sample are consistent with an average ratio of the continuum attenuation to the nebular gas of 0.44, but with a large amount of excess scatter beyond the observational uncertainties. Much of this scatter is linked to a large variation between the nebular dust attenuation as measured by (space-based) $\Pab$ to (ground-based) $\Ha$ to that from (ground-based) $\Ha/\Hb$. This implies there are important differences between attenuation measured from grism-based / wide-aperture $\Pab$ fluxes and the ground-based / slit-measured Balmer decrement. We next compare star-formation rates (SFRs) from $\Pab$ to those from dust-corrected UV. We perform a survival analysis to infer a census of \Pab\ emission implied by both detections and non-detections. We find evidence that galaxies with lower stellar mass have more scatter in their ratio of \Pab\ to attenuation-corrected UV SFRs. When considering our \Pab\ detection limits, this observation supports the idea that lower mass galaxies experience "burstier" star-formation histories. Together, these results show that \Pab\ is a valuable tracer of a galaxy's SFR, probing different timescales of star-formation and potentially revealing star-formation that is otherwise missed by UV and optical tracers.

description: According to earlier Doppler images of the magnetically active primary giant component of the RS CVn binary II Peg, the surface of the star was dominated by one single active longitude that was clearly drifting in the rotational frame of the binary system during 1994-2002; later imaging for 2004-2010, however, showed decreased and chaotic spot activity, with no signs of the drift pattern. Here we set out to investigate from a more extensive photometric dataset whether such a drift is a persistent phenomenon, in which case it could be due to either an azimuthal dynamo wave or an indication of the binary system orbital synchronization still being incomplete. We analyse the datasets using the Carrier Fit method (hereafter CF), especially suitable for analyzing time series in which a fast clocking frequency (such as the rotation of the star) is modulated with a slower process (such as the stellar activity cycle). We combine all collected photometric data into one single data set, and analyze it with the CF method. As a result, we confirm the earlier results of the spot activity having been dominated by one primary spotted region almost through the entire data set, and the existence of a persistent, nearly linear drift. Disruptions of the linear trend and complicated phase behavior are also seen, but the period analysis reveals a rather stable periodicity with P(spot)=6.71054d plus/minus 0.00005d. After the linear trend is removed from the data, we identify several abrupt phase jumps, three of which are analyzed in more detail with the CF method. These phase jumps closely resemble what is called flip-flop event, but the new spot configurations do not, in most cases, persist for longer than a few months.

description: We consider varieties of representations and characters of 2 and 3-dimensional orbifolds in semisimple Lie groups, and we focus on computing their dimension. For hyperbolic 3-orbifolds, we consider the component of the variety of characters that contains the holonomy composed with the principal representation, we show that its dimension equals half the dimension of the variety of characters of the boundary. We also show that this is a lower bound for the dimension of generic components. We furthermore provide tools for computing dimensions of varieties of characters of 2-orbifolds, including the Hitchin component. We apply this computation to the dimension growth of varieties of characters of some 3-dimensional manifolds in SL(n,C).

description: This paper deals with the solution of the spherically symmetric time-dependent Hartree-Fock approximation applied to nuclear giant monopole resonances in the small amplitude regime. The problem is spatially unbounded as the resonance state is in the continuum. The practical requirement to perform the calculation in a finite-sized spatial region yields an artificial boundary, which is not present physically. The question of how to ensure the boundary does not interfere with the internal solution, while keeping the overall calculation time low is studied. Here we propose an absorbing boundary condition scheme to handle the conflict. The derivation, via a Laplace transform method, and implementation is described. An inverse Laplace transform required by the absorbing boundaries is calculated using a method of non-linear least squares. The accuracy and efficiency of the scheme is tested and results presented to support the case that they are a effective way of handling the artificial boundary.

title: Hold as a Monosemic Verb
Creators: name: Camp, Amy D.
Publisher: name: Old Dominion University Libraries
Year: 1995

description: The verb hold is normally presumed to be highly polysemous; dictionaries ascribe to it several senses and sub-senses. This treatment is supported by the polysemous bias in current semantic research. In this thesis, I claim that hold is monosemic, with ascribed meanings resulting from pragmatic modulation. My treatment of hold is based on Charles Ruhl's work with monosemy in his book On Monosemy: A Study in Linguistic Semantics.

This study isolates hold's constant semantic contribution throughout 250 diverse example sentences. I claim that hold: (1) presupposes a sequence, and then (2) suspends the sequence.

After an introduction and a chapter on current treatments of hold, I present simple transitives (chapter 3) and then a look at objects modified by adjectives and the possibility of small clauses (chapter 4). Also covered are example sentences containing phrasal verbs (chapter 5) and idioms (chapter 6). A sampling of prepositional phrases and their impact on hold is presented in chapters 7 and 8.

title: The Complexities of Learning Prepositions: Spanish to English
Creators: name: Chiavarini, Denise J. Simon
Publisher: name: Old Dominion University Libraries
Year: 1993

description: This study explores reasons for the improper use of English pronouns by Spanish speaking ESL students, as evidenced in the Free Writing Placement Tests given at The Adult Learning Center in Virginia Beach and Old Dominion University.

The database includes 84 examples of prepositional errors (Appendix B) that were translated into Spanish for comparison and analysis. Some errors can be attributed to first language interference (Chapter 2, Contrastive Analysis). Some can be attributed to interlanguage (Chapter 3, Error Analysis). Other chapters show additional complications such as variation in native speaker preposition use and the effects of some prepositional contexts. Although the study started with the goal of developing an effective way to teach prepositions, the discussion here shows that the problem is highly complex.

Included, also, is a study of current pedagogy with summaries and a grammar book bibliography which can be used as a source of materials for teaching or supplementing preposition lessons.
Sparse Dynamics for Partial Differential Equations

description: We investigate the approximate dynamics of several differential equations when the solutions are restricted to a sparse subset of a given basis. The restriction is enforced at every time step by simply applying soft thresholding to the coefficients of the basis approximation. By reducing or compressing the information needed to represent the solution at every step, only the essential dynamics are represented. In many cases, there are natural bases derived from the differential equations which promote sparsity. We find that our method successfully reduces the dynamics of convection equations, diffusion equations, weak shocks, and vorticity equations with high frequency source terms.
How to design quantum-jump trajectories via distinct master equation representations

description: Every open-system dynamics can be associated to infinitely many stochastic pictures, called unravelings, which have proved to be extremely useful in several contexts, both from the conceptual and the practical point of view. Here, focusing on quantum-jump unravelings, we demonstrate that there exists inherent freedom in how to assign the terms of the underlying master equation to the deterministic and jump parts of the stochastic description, which leads to a number of qualitatively different unravelings. As relevant examples, we show that a fixed basis of post-jump states can be selected under some definite conditions, or that the deterministic evolution can be set by a chosen time-independent non-Hermitian Hamiltonian, even in the presence of external driving. Our approach relies on the definition of rate operators, whose positivity equips each unraveling with a continuous-measurement scheme and is related to a long known but so far not widely used property to classify quantum dynamics, known as dissipativity. Starting from formal mathematical concepts, our results allow us to get fundamental insights into open quantum system dynamics and to enrich their numerical simulations.

Critical scaling in random-field systems: 2 or 3 independent exponents?

description: We show that the critical scaling behavior of random-field systems with short-range interactions and disorder correlations cannot be described in general by only two independent exponents, contrary to previous claims. This conclusion is based on a theoretical description of the whole (d,N) domain of the d-dimensional random-field O(N) model and points to the role of rare events that are overlooked by the proposed derivations of two-exponent scaling. Quite strikingly, however, the numerical estimates of the critical exponents of the random field Ising model are extremely close to the predictions of the two-exponent scaling, so that the issue cannot be decided on the basis of numerical simulations.

title: A Literary Evaluation of Black Female Interaction in Toni Morrison's "Beloved", "Sula," "Jazz"
Creators: name: Davenport, Carol Ann
Publisher: name: Old Dominion University Libraries
Year: 1994

description: This Master's thesis consists of three chapters that examine the roles, circumstances and effects of racism and sexism on the black female characters in three of Toni Morrison's novels, Beloved, Sula and Jazz. I propose that the elements of racism and sexism have left the female characters, Sethe, Denver, Ella, etc. in Beloved with few choices in life. Further, I suggest that the theme of "choice versus no choice" perpetuates hatred and self-hatred among black women and results in "metaphoric scarring." I explore in the characters, Sula, Eva, Hannah, Nel, and the black Bottom women, the damage inflicted on black women in the novel Sula. Consequently, the patterns of blatant racism, subtle racism and sexism demand some form of intervention to heal these black women. The theme of healing is the ideal undergirding reconciliation in the novel Jazz.

A version of "Reconciliation in Toni Morrison's Jazz" was presented at the Works-In-Progress Conference at Old Dominion University in May, 1994. A modification of this same chapter was presented at the Mid-Atlantic Writer's Association Conference in October, 1992. A variant of "Choice versus No Choice" was presented at the First Annual Old Dominion University Graduate Conference in 1993.
title: Katharine's Dream
Creators: name: Maceira, Karen
Publisher: name: Old Dominion University Libraries
Year: 1993

description: Katharine's Dream is about a girl born into a family of great passion and great fear. Not all members of the family survive this devastating combination. These poems tell of who survived and how, and of who did not.

The poems are predominantly free verse lyrics which use standard diction and syntax. More often than not, they employ a short line, dense imagery and "white space," which frames the images and ideas, in the words of Mary Oliver, with the necessary "silence." Though the rhythms of some of the poems flow among smoothly, line breaks in others often suggest the hesitation of one coping with an inner ambivalence.

The manuscript is divided into two parts. The first, "The Twilight Fishermen," deals with Katharine's life when young. The second part, "Desire," tells of her experiences as she gets older.

description: In this paper, we investigate the thermodynamics of Lifshitz black branes in the presence of a nonlinear massless electromagnetic field. We begin by introducing the appropriate action in grand-canonical and canonical ensembles for nonlinear electromagnetic field. The condition on the parameters of the metric for having black brane solutions will be presented. Since the field equations cannot be solved for an arbitrary value of the critical exponent $z$, we obtain a conserved quantity along the $r$ coordinate that enables us to relate the parameters of the metric at the horizon and at infinity. Then, we calculate the energy density of the Lifshitz black brane through the use of the counterterm method generalized for the asymptotic Lifshitz spacetimes. Finally, we present a relation between the energy density and the thermodynamical quantities, electric potential, charge density, temperature and entropy density. This relation is the generalization of Smarr formula for anti-de Sitter black branes.

description: Ultra-long-chain fatty acids (ULCFAs) are biosynthesized in the restricted tissues such as retina, testis, and skin. The conformation of a single ULCFA, in which the sn-1 unsaturated chain has 32 carbons, in three types of tensionless phospholipid bilayers is studied by molecular dynamics simulations. It is found that the ultra-long tail of the ULCFA flips between two leaflets and fluctuates among an elongation into the opposite leaflet, lying between two leaflets, and turning back. As the number ratio of lipids in the opposite leaflet increases, the ratio of the elongated shape linearly decreases in all three cases. Thus, ULCFAs can sense the density differences between the two leaflets and respond to these changes.
