Cerebral morphometry in monozygotic and dizygotic twins: A study of heritability
Creators: name: Luevano, Laura Frances
Publisher: name: American University
Year: 2023

description: This study investigates whether there is a genetic component in cerebral development as measured by: (1) the degree of asymmetry between the frontal and occipital lobes; and (2) the complexity of gyral patterns, as measured by the gyrification index (GI). We measured frontal and occipital lobe volumes and the GI in 9 strongly right-handed normal dizygotic (DZ) twins pairs and 9 strongly right-handed normal monozygotic (MZ) twin pairs. Results confirmed normal asymmetry of lobe volume in both sets of twins, and GI measurements were comparable to those in previous studies. Within-twin comparisons of the relationship between frontal and occipital lobe volume showed a significant association for MZ, but not DZ, twin pairs, indicating strong heritability for this asymmetry. Within-twin comparisons of the GI showed a strong association for both MZ and DZ twins, indicating a strong environmental component in the development of gyral patterns.

description: The paper investigates the relationship between time consistency and subgame perfection. We show that despite some suggestions in the literature, the two are not equivalent. Subgame perfection is a stronger refinement. The paper also discusses the classes of .games in which time consistency and subgame perfection are equivalent.
Wavelet representation of light-front quantum field theory

Subjects: subject: High Energy Physics - Theory (hep-th)

description: A formally exact discrete multi-resolution representation of quantum field theory on a light front is presented. The formulation uses an orthonormal basis of compactly supported wavelets to expand the fields restricted to a light front. The representation has a number of useful properties. First, light front preserving Poincaré transformations can be computed by transforming the arguments of the basis functions. The discrete field operators, which are defined by integrating the product of the field and the basis functions over the light front, represent localized degrees of freedom on the light-front hyperplane. These discrete fields are irreducible and the vacuum is formally trivial. The light-front Hamiltonian and all of the Poincaré generators are linear combinations of normal ordered products of the discrete field operators with analytically computable constant coefficients. The representation is discrete and has natural resolution and volume truncations like lattice formulations. Because it is formally exact it is possible to systematically compute corrections for eliminated degrees of freedom.

description: We present a fully quantum mechanical treatment of the nondegenerate optical parametric oscillator both below and near threshold. This is a non-equilibrium quantum system with a critical point phase-transition, that is also known to exhibit strong yet easily observed squeezing and quantum entanglement. Our treatment makes use of the positive P-representation and goes beyond the usual linearized theory. We compare our analytical results with numerical simulations and find excellent agreement. We also carry out a detailed comparison of our results with those obtained from stochastic electrodynamics, a theory obtained by truncating the equation of motion for the Wigner function, with a view to locating regions of agreement and disagreement between the two. We calculate commonly used measures of quantum behavior including entanglement, squeezing and EPR correlations as well as higher order tripartite correlations, and show how these are modified as the critical point is approached. In general, the critical fluctuations represent an ultimate limit to the possible entanglement that can be achieved in a nondegenerate parametric oscillator.
Final rights: An international comparative study of euthanasia regulations and right-to-die issues
Creators: name: Scherer, Jennifer M.

description: Euthanasia, at its most basic translation, simply means a "good death" or "dying well." The debates surrounding euthanasia and physician-assisted suicide have focused on the wish for control and influence over the manner and timing of one's death. The basic premise contrasts maintaining personal dignity throughout the dying process and relieving severe pain effectuated by terminal illness, as opposed to warnings about the potential for abuse by physicians, family members, health insurance companies and society at large. These concerns are generally termed the "slippery slope" or "wedge" issues. In addition, the debate struggles with traditional religious doctrines, social mores and philosophical attitudes concerning the value and meaning of life, the redemptive virtues of suffering, and the moral and societal taboos against the act of suicide, assisting suicide or being directly involved in causing another individual's death. To examine death and dying divorced from their many sociocultural milieus would be meaningless and inappropriate. Endeavoring to obtain a premature death through euthanasia or physician-assisted suicide is not solely the product of the progress that medical science has achieved; requests to hasten death also rely on the prevailing moral and political atmosphere of a society. As religion and religious institutions began to lose their guiding moral authority in society, laws piloting the conduct of individuals gradually grew more secular in nature, recognizing individual choice and personal freedoms. This dissertation examines several social indicators on an international scale, including the type of government or political infrastructure, form of legal system, dominant religion, existence of a health-care system and the life-expectancy rate to predict the liberalness or restrictiveness of the existing euthanasia and/or physician-assisted suicide regulation in a country. Special emphasis is placed on the examination of regulatory concerns in Columbia, Australia, The Netherlands, and the United States, where precedents in the euthanasia debate are being set. The prospect of legalization and the direction and future of the debate are also explored.
Exactly solvable Schrödinger operators related to the confluent equation

description: Our paper investigates one-dimensional Schrödinger operators defined as closed operators on $L^2(\mathbb{R})$ or $L^2(\mathbb{R}_+)$ that are exactly solvable in terms of confluent functions (or, equivalently, Whittaker functions). We allow the potentials to be complex. They fall into three families: Whittaker operators (or radial Coulomb Hamiltonians), Schrödinger operators with Morse potentials and isotonic oscillators. For each of them, we discuss the corresponding basic holomorphic family of closed operators and the integral kernel of their resolvents. We also describe transmutation identities that relate these resolvents. These identities interchange spectral parameters with coupling constants across different operator families.
 A similar analysis is performed for one-dimensional Schrödinger operators solvable in terms of Bessel functions (which are reducible to special cases of Whittaker functions). They fall into two families: Bessel operators and Schrödinger operators with exponential potentials.
 To make our presentation self-contained, we include a short summary of the theory of closed one-dimensional Schrödinger operators with singular boundary conditions. We also provide a concise review of special functions that we use.

description: Adult attachment style was examined in one hundred and thirteen same-sex freshman roommate pairs enrolled in their first semester at American University. It was hypothesized that both attachment style and depression symptom level would associate with students' self-reported roommate relationship functioning. The present study indicates that students tend to select different attachment categories for different kinds of relationships. Further, attachment style was associated with students' reports of roommate relationship functioning. Roommate pairs in which both members were insecure reported significantly lower roommate relationship functioning than pairs in which at least one member was secure. Depression symptom level did not associate with relationship functioning.
Governing aesthetics: form and politics in Black hemispheric literature
Creators: name: Martino, Ariel Fraser
Publisher: name: No Publisher Supplied
Year: 2021

description: Governing Aesthetics argues that literature provides a generative testing ground for theorizing the formation of political subjectivity. This is, in part, because the flexibility of literary form allows Black authors to balance and re-balance the calculus of inclusion in and diversion from nationalist paradigms. I read a range of authors from the United States and Caribbean, including C.L.R. James, Zora Neale Hurston, Angelo Herndon, Hosea Hudson, Nate Shaw, Jacques Roumain, Claude McKay, Gwendolyn Brooks, and Margaret Walker. These writers use literary forms like the novel, the autobiographical narrative, the lyric poem, and tragic drama that traditionally centralize a singular protagonist, adapting established forms in order to posit alternate models of political participation that challenge notions of liberal individualism. I look to texts that seem to value masculine exceptionality, uphold the tenets of Western Enlightenment, or challenge radical political praxis to argue that the authors present structural complications that are incipient theorizations of political alternatives. These theorizations provide more complete ideological and historical context to the gains and upheavals of the 1960s and, in returning to a historical moment when these ideas were still in formation, I uncover some assumptions that undergird them.

Entanglement transfer from quantum matter to classical geometry in an emergent holographic dual description of a scalar field theory

description: Applying recursive renormalization group transformations to a scalar field theory, we obtain an effective quantum gravity theory with an emergent extra dimension, described by a dual holographic Einstein-Klein-Gordon type action. Here, the dynamics of both the dual order-parameter field and the metric tensor field originate from density-density and energy-momentum tensor-tensor effective interactions, respectively, in the recursive renormalization group transformation, performed approximately in the Gaussian level. This linear approximation in the recursive renormalization group transformation for the gravity sector gives rise to a linearized quantum Einstein-scalar theory along the $z-$directional emergent space. In the large $N$ limit, where $N$ is the flavor number of the original scalar fields, quantum fluctuations of both dynamical metric and dual scalar fields are suppressed, leading to a classical field theory of the Einstein-scalar type in $(D+1)$-spacetime dimensions. We show that this emergent background gravity describes the renormalization group flows of coupling functions in the UV quantum field theory through the extra dimension. More precisely, the IR boundary conditions of the gravity equations correspond to the renormalization group $β$-functions of the quantum field theory, where the infinitesimal distance in the extra-dimensional space is identified with an energy scale for the renormalization group transformation. Finally, we also show that this dual holographic formulation describes quantum entanglement in a geometrical way, encoding the transfer of quantum entanglement from quantum matter to classical gravity in the large $N$ limit. We claim that this entanglement transfer serves as a microscopic foundation for the emergent holographic duality description.

description: Drawing upon a broad range of disciplines, such as literary theory, visual semiotics, pragmatics, sound symbolism and media studies, this article will introduce, explore and define the relationship between words and pictures in imagetexts. It will then apply these findings to the discourse concerning the use of expressive sound symbolic forms in comics, in order to elucidate the ambivalent relationship that these intrusive sensorial elements have with images as presented in comics and with their younger audiences. In particular, this article will show how the presence of ‘lettering’ (e.g. textual features) fosters the dynamicity of the genre but, at the same time, poses issues when it comes to defining its close amalgamation with the visual image. The dual main aim is, first, to show how the presence of onomatopoeia shapes the way we perceive the conventions of imagetexts, comics above all, and, secondly, to underline the importance of the younger reader as a ‘self-regulating’ protagonist in the process.

description: The lowest-order Neural Approximated Virtual Element Method on polygonal elements is proposed here. This method employs a neural network to locally approximate the Virtual Element basis functions, thereby eliminating issues concerning stabilization and projection operators, which are the key components of the standard Virtual Element Method. We propose different training strategies for the neural network training, each correlated by the theoretical justification and with a different level of accuracy. Several numerical experiments are proposed to validate our procedure on general polygonal meshes and demonstrate the advantages of the proposed method across different problem formulations, particularly in cases where the heavy usage of projection and stabilization terms may represent challenges for the standard version of the method. Particular attention is reserved to triangular meshes with hanging nodes which assume a central role in many virtual element applications.

description: Systems with the quantum numbers of up to twelve charged and neutral pseudoscalar mesons, as well as one-, two-, and three-nucleon systems, are studied using dynamical lattice quantum chromodynamics and quantum electrodynamics (QCD+QED) calculations and effective field theory. QED effects on hadronic interactions are determined by comparing systems of charged and neutral hadrons after tuning the quark masses to remove strong isospin breaking effects. A non-relativistic effective field theory, which perturbatively includes finite-volume Coulomb effects, is analyzed for systems of multiple charged hadrons and found to accurately reproduce the lattice QCD+QED results. QED effects on charged multi-hadron systems beyond Coulomb photon exchange are determined by comparing the two- and three-body interaction parameters extracted from the lattice QCD+QED results for charged and neutral multi-hadron systems.

description: We consider a model for the reionization history of the Universe in which a significant fraction of the observed optical depth is a result of direct reionization by the decay products of a scaling cosmic defect network. We show that such network can make a significant contribution to the reionization history of the Universe even if its energy density is very small (the defect energy density has to be greater than about $10^{-11}$ of the background density). We compute the Cosmic Microwave Background temperature, polarization and temperature-polarization cross power spectrum and show that a contribution to the observed optical depth due to the decay products of a scaling defect network may help to reconcile a high optical depth with a low redshift of complete reionization suggested by quasar data. However, if the energy density of defects is approximately a constant fraction of the background density then these models do not explain the large scale bump in the temperature-polarization cross power spectrum observed by WMAP.

Stochastic dynamics in financial markets: An empirical investigation
Creators: name: Rwaga, George
Publisher: name: American University
Year: 2023

description: Two well documented empirical regularities in asset markets, leptokurtosis and clustered volatility, are essential for logically consistent and correct financial models as well as exact statistical tests. These regularities also have serious implications for the capital asset pricing model, the option pricing model and the efficient market hypothesis. The GARCH process essentially models time-varying variance or volatility clustering. To determine the exact form of error distribution, and hence the correct probability distribution of stock price changes, this study examined the GARCH model under two distributional assumptions: the normal and the power exponential. The GARCH process was further extended to model factors violating the iid assumption--autocorrelation, the day-of-the-week and seasonality. The study extends previous research in two specific ways. One, it estimates for the first time a GARCH model with a power exponential error distribution that accounts for the day-of-the week and seasonality effects in both the mean and variance. Two, the study employs more recent data. The GARCH models are estimated, for the most part, by the Broyden-Fletcher-Goldfarb-Shanno (BFGS) algorithm with a cubic or quadratic (STEPBT) line search method within the framework of the Constrained Maximum Likelihood (CML) Gauss module. The evidence shows that the GARCH-pe process fits the sample data better than the GARCH-n process. Nonlinear dependence in the raw data was not removed in all cases, although linear dependence and observed leptokurtosis were reduced significantly. Unfortunately, both GARCH processes were rejected for all indices. Different volatility in returns for each day of the week is the most prevalent of all the market anomalies. The weekend effect on variance is confirmed for NASDAQ. Low variances on Wednesdays are not supported. Seasonal volatility in returns is considerable. Different mean returns for each day of the week is not a widespread phenomenon. The weekend effect on the mean is weak and only for NASDAQ. Higher Wednesday returns find limited support. Seasonal differences in mean returns is detected in only a few cases.

description: We study the dynamics of iterated cosine maps $E\colon z \mapsto ae^z+be^{-z},$ with $a,b \in \C\setminus \{0\}$. We show that the points which converge to infinity under iteration are organized in the form of rays and, as in the exponential family, every escaping point is either on one of these rays or the landing point of a unique ray. Thus we get a complete classification of the escaping points of the cosine family, confirming a conjecture of Eremenko in this case. We also get a particularly strong version of the ``dimension paradox'': the set of rays has Hausdorff dimension 1, while the set of points these rays land at has not only Hausdorff dimension 2 but infinite planar Lebesgue measure.

The hydrogen atom has a nucleus consisting of a proton bearing one unit of positive electrical charge; an electron, bearing one unit of negative electrical charge, is also associated with this nucleus. Under ordinary conditions, hydrogen gas is a loose aggregation of hydrogen molecules, each consisting of a pair of atoms, a diatomic molecule. The earliest known important chemical property of hydrogen is that it burns with oxygen to form water; indeed, the name hydrogen is derived from Greek words meaning maker of water.

description: A sustainable one-pot three-component synthesis of novel 1H-pyrazolo[1,2-a]pyridazine-2-carbonitrile derivatives employing a highly efficient, biodegradable, and recyclable choline hydroxide catalyst under solvent-free conditions is demonstrated. The salient features of this protocol are simple workup, mild reaction conditions, short reaction time (10 min), excellent yields (up to 97%), high atom economy, column chromatography-free protocol, and eco-friendliness. Interestingly, the choline hydroxide was recycled up to five cycles without any considerable loss of efficiency. The structures of the products were deduced by their 1H NMR, 13C NMR, and HRLC-MS spectra.

Carbon dioxide in particular has been intensely studied, yet little is known about the supercritical part of its phase diagram. Here, we combine neutron scattering experiments and molecular dynamics simulations and demonstrate the structural crossover at the Frenkel line. The crossover is seen at pressures as high as 14 times the critical pressure and is evidenced by changes of the main features of the structure factor and pair distribution functions.

description: This study examines the factors that contribute to the success of interest groups focused on physical disability in getting what they want written into a bill and thus placed on the legislative agenda. Identification of the actual study groups is made via legislative hearing records from the period 1983-1989. An analysis of hearing testimony in the House of Representatives' Committee on Education and Labor is made to determine the specific positions identified groups were advocating and the degree to which the positions were reflected in the bill being considered, i.e., the degree of legislative success--the dependent variable. Independent variables believed to influence that success include various characteristics of the group and its members and constituents, the group's congressional testimony, the legislators involved in hearings where such testimony was presented, and the hearing itself. Information about both the dependent and independent variables comes from a variety of sources including interviews, legislative calendars, printed hearing documents, bill texts, public tax records, reference volumes, and other secondary materials. The collected data are analyzed using ordinal-level descriptive statistics and logistic regression techniques. Results of these analyses provide evidence on the relative importance or unimportance of what a group actually does on its own behalf. Study findings indicate that the resources a group commands and the actions it takes may not be as important as originally hypothesized here or traditionally thought in social science literature. The particular emphasis given here to groups concerned with disability is one currently absent from existing interest group literature, and this study is an attempt to fill that void.

Information about both the dependent and independent variables comes from a variety of sources including interviews, legislative calendars, printed hearing documents, bill texts, public tax records, reference volumes, and other secondary materials. The collected data are analyzed using ordinal-level descriptive statistics and logistic regression techniques. Results of these analyses provide evidence on the relative importance or unimportance of what a group actually does on its own behalf. Study findings indicate that the resources a group commands and the actions it takes may not be as important as originally hypothesized here or traditionally thought in social science literature. The particular emphasis given here to groups concerned with disability is one currently absent from existing interest group literature, and this study is an attempt to fill that void.

description: In the Stanley lattice defined on Dyck paths of size $n$, cover relations are obtained by replacing a valley $DU$ by a peak $UD$. We investigate a greedy version of this lattice, first introduced by Chenevière, where cover relations replace a factor $DU^k D$ by $U^kD^2$. By relating this poset to another poset recently defined by Nadeau and Tewari, we prove that this still yields a lattice, which we call the ascent lattice $L_n$.
 We then count intervals in $L_n$. Their generating function is found to be algebraic of degree $3$. The proof is based on a recursive decomposition of intervals involving two catalytic parameters. The solution of the corresponding functional equation is inspired by recent work on the enumeration of walks confined to a quadrant.
 We also consider the order induced in $L_{mn}$ on $m$-Dyck paths, that is, paths in which all ascent lengths are multiples of $m$, and on mirrored $m$-Dyck paths, in which all descent lengths are multiples of $m$. The first poset $L_{m,n}$ is still a lattice for any $m$, while the second poset $L'_{m,n}$ is only a join semilattice when $m>1$. In both cases, the enumeration of intervals is still described by an equation in two catalytic variables. Interesting connections arise with the sylvester congruence of Hivert, Novelli and Thibon, and again with walks confined to a quadrant. We combine the latter connection with probabilistic results to give asymptotic estimates of the number of intervals in both $L_{m,n}$ and $L'_{m,n}$. Their form implies that the generating functions of intervals are no longer algebraic, nor even D-finite, when $m>1$.

DNA repair of trans-(+)-anti-, ($-$)-anti-, (+)-syn, and ($-$)-syn-benzo(a);pyrene diol epoxides using human cell extracts: Effects of sequence context and adduct stereochemistry

description: Lung cancer is the leading cause of cancer deaths in the U.S. Benzo (a) pyrene, a component of cigarette smoke, produces DNA adducts in lung tissue. Mutation and epidemiologic data suggest that persistent unrepaired benzo (a) pyrene diol epoxide (BPDE) adducts are responsible for some mutation hot spots and lung cancers. The +2 BPDE isomer has been shown to be far more mutagenic, and tumorigenic than the other isomers. Different repair rates between BPDE stereoisomers has been proposed as a contributing factor to the mutagenic and tumorigenic activity of BP. In this work the effect of adduct stereochemistry and sequence context on the extent and rate of DNA repair were investigated. Covalently-closed-plasmids containing a site-specific single trans (+)-anti-, $({-})$-anti-, (+)-syn-, or $({-})$-syn-benzo (a) pyrene diol epoxide were constructed. The adduct was attached to $\rm G\sb1$ or $\rm G\sb2$ of the K-ras codon 12 sequence, $5\sp\prime$-$\rm GCTG\sb1G\sb2TGGC$-$3\sp\prime .$ Extent and rate of repair were determined using human whole cell extracts in an in vitro repair synthesis assay. Both repair rate and extent were dependent upon adduct stereochemistry. Overall repair efficiency decreased in the following order: ${+}2\ge{-}1\ge{+}1\gg{-}2.$ Repair efficiency was ${\sim}6$-fold higher for the +2 isomer compared to the ${-}2$ isomer. Although others have found sequence context differences in repair, for the $\rm TG\sb1G\sb2T$ sequence extent and rate of repair was independent of adduct position. To determine if inefficient repair of the ${-}2$ adduct was due to difficulty in making the $3\sp\prime$ incision, single lesion plasmids were prepared that contained a nick at the 6th phosphodiester bond $3\sp\prime$ to the adducted base. The overall repair signal increased for nicked constructs compared to the single lesion closed-circular-constructs and repair for the ${-}2$ adduct increased to +2 levels. Although this study does not support inefficient repair as a basis for increased +2 mutagenicity, it does suggest that BPDE adducts persist in human cells because they are poorly repaired.

description: New experimental tests of nuclear supersymmetry are suggested. They involve the measurement of one- and two-nucleon transfer reactions between nuclei that belong to the same supermultiplet. These reactions provide a direct test of the `fermionic' sector, i.e. of the operators that change a boson into a fermion or vice versa. We present some theoretical predictions for the supersymmetric quartet of nuclei: 194Pt, 195Pt, 195Au and 196Au.

description: Adamantane-derived aldo- and ketonitrones react with maleimides giving corresponding isoxazolidines. In the case of aldonitrones reactions proceed giving the diastereomeric mixtures. The ratio of isomers is changing during the reaction process due to the reversibility of the cycloaddition reaction. The cytotoxic and virus-inhibiting activity against influenza virus was investigated for selected adducts.
