description: We study the Electric Dipole moment of b quark in the general two Higgs Doublet model (model III) and three Higgs Doublet model with O(2) symmetry in the Higgs sector. We analyse the dependency of this quantity to the new phase coming from the complex Yukawa couplings and masses of charged and neutral Higgs bosons. We see that the Electric Dipole moment of b quark is at the order of 10^{-20} e cm, which is an extremely large value compared to one calculated in the SM and also two Higgs Doublet model (model II) with real Yukawa couplings.

We provide an analytical formula for these new hitherto missing quasinormal modes, and in doing that we also construct a generalization of the Gauss convergence criterion.

description: Different from salient object detection methods for still images, a key challenging for video saliency detection is how to extract and combine spatial and temporal features. In this paper, we present a novel and effective approach for salient object detection for video sequences based on 3D convolutional neural networks. First, we design a 3D convolutional network (Conv3DNet) with the input as three video frame to learn the spatiotemporal features for video sequences. Then, we design a 3D deconvolutional network (Deconv3DNet) to combine the spatiotemporal features to predict the final saliency map for video sequences. Experimental results show that the proposed saliency detection model performs better in video saliency prediction compared with the state-of-the-art video saliency detection methods.

description: The Drosophila metallothionein promoter (Mtn) was used to obtain efficient, regulated expression of foreign gene products inserted in high copy numbers into Drosophila melanogaster Schneider 2 cells. An expression unit comprised of a reporter gene [Escherichia coli galactokinase (galK)] fused to the Mtn promoter was stably introduced into Schneider 2 cells in up to several hundred copies per cell in a single transfection-selection event. This system contrasts dramatically with other eukaryotic systems that permit only a few copies of a gene to be stably inserted in a single transfection-selection event. The transfected Drosophila S2 cell lines expressed high levels of both galK mRNA and protein in response to metal induction. Most important, and in contrast to mammalian cells, expression remained fully regulated even at high copy number, with low basal expression maintained in the absence of inducer. This regulated system was used to obtain efficient expression in Drosophila cells of an otherwise lethal or growth-inhibitory gene product, the human H-ras oncogene. The ability to obtain regulated high-level expression of potentially lethal foreign proteins is unique to the Drosophila cell system.

description: Understanding the molecular mechanism of specific and polarized termination of DNA replication at a sequence-specific replication terminus requires detailed analyses of the interaction of terminator protein (ter) with specific DNA sequences (tau), constituting the replication terminus. Such analyses should provide the structural basis of the functional polarity of replication inhibition observed in vivo and in vitro at tau sites. With this objective in mind, we have purified the replication terminator protein of Escherichia coli to homogeneity and have analyzed the interaction of the protein with the replication termini of R6K, using chemical probes and by site-directed mutagenesis. The results show that one monomer of ter protein binds to a single tau site with an equilibrium dissociation constant of 5 x 10(-9) moles/liter. Furthermore, a combination of alkylation interference and protection, hydroxyradical footprinting, and site-directed mutagenesis has revealed the phosphate groups and base residues of the tau core sequence that make contacts with ter protein and those residues that are important for both DNA-protein interaction and for termination of replication in vivo. The overall picture that emerges from these analyses reveals that ter forms an asymmetric complex with a tau sequence. Thus, the asymmetric ter-tau complex provides a structural basis for the functional polarity of the arrest of a moving replication fork at a tau site.

description: We present an analysis of archival observations with the Atacama Large (sub-)Millimetre Array (ALMA) of the gravitationally lensed quasar MG J0414+0534, which show four compact images of the quasar and an Einstein ring from the dust associated with the quasar host galaxy. We confirm that the flux-ratio anomalies observed in the mid-infrared and radio persists into the sub-mm for the continuum images of the quasar. We report the detection of CO (11-10) spectral line emission, which traces a region of compact gas around the quasar nucleus. This line emission also shows evidence of a flux-ratio anomaly between the merging lensed images that is consistent with those observed at other wavelengths, suggesting high-excitation CO can also provide a useful probe of substructures that is unaffected by microlensing or dust extinction. However, we do not detect the candidate dusty dwarf galaxy that was previously reported with this dataset, which we conclude is due to a noise artefact. Thus, the cause of the flux-ratio anomaly between the merging lensed images is still unknown. The composite compact and diffuse emission in this system suggest lensed quasar-starbursts will make excellent targets for detecting dark sub-haloes and testing models for dark matter.

Structural and Magnetic Properties of Trigonal Iron

Year: 1995
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: First principles calculations of the electronic structure of trigonal iron were performed using density function theory. The results are used to predict lattice spacings, magnetic moments and elastic properties; these are in good agreement with experiment for both the bcc and fcc structures. We find however, that in extracting these quantities great care must be taken in interpreting numerical fits to the calculated total energies. In addition, the results for bulk iron give insight into the properties of thin iron films. Thin films grown on substrates with mismatched lattice constants often have non-cubic symmetry. If they are thicker than a few monolayers their electronic structure is similar to a bulk material with an appropriately distorted geometry, as in our trigonal calculations. We recast our bulk results in terms of an iron film grown on the (111) surface of an fcc substrate, and find the predicted strain energies and moments accurately reflect the trends for iron growth on a variety of substrates.

description: Limb morphogenesis is an excellent model system to study pattern formation during vertebrate development. The legless (lgl) insertional mutation can serve as a tool to analyze specific events in limb development at the embryologic, genetic, and molecular levels. Hemizygous mice of this transgenic line are phenotypically normal, but homozygous mutants are inviable and exhibit limb, brain, and craniofacial malformations, as well as situs inversus. By morphological analysis of mutant hindlimb buds we show absence of a normal apical ectodermal ridge, a structure required for limb bud outgrowth, and an unusually high degree of mesenchymal and ectodermal cell death. Mutant embryos are extremely sensitive to retinoic acid, a known teratogen with a proposed role in limb development. The hindlimb malformations in legless mutants are less severe when bred into the BALB/c background, suggesting the involvement of other strain-specific genes. Molecular analysis of the disrupted region indicates two tightly linked insertion sites. Sequences flanking the transgene insertions have been cloned and mapped to chromosome 12, near the iv (situs inversus viscerum) locus. Consistent with this, complementation tests confirm allelism of lgl and iv and suggest that the transgene insertion may have disrupted more than one gene. Phylogenetically conserved sequences flanking the transgene insertions were identified and used to isolate candidate lgl and iv cDNAs.

description: While investments in renewable energy sources (RES) are incentivized around the world, the policy tools that do so are still poorly understood, leading to costly misadjustments in many cases. As a case study, the deployment dynamics of residential solar photovoltaics (PV) invoked by the German feed-in tariff legislation are investigated. Here we report a model showing that the question of when people invest in residential PV systems is found to be not only determined by profitability, but also by profitability's change compared to the status quo. This finding is interpreted in the light of loss aversion, a concept developed in Kahneman and Tversky's Prospect Theory. The model is able to reproduce most of the dynamics of the uptake with only a few financial and behavioral assumptions

description: Vascular graphs can embed a number of high-level features, from morphological parameters, to functional biomarkers, and represent an invaluable tool for longitudinal and cross-sectional clinical inference. This, however, is only feasible when graphs are co-registered together, allowing coherent multiple comparisons. The robust registration of vascular topologies stands therefore as key enabling technology for group-wise analyses. In this work, we present an end-to-end vascular graph registration approach, that aligns networks with non-linear geometries and topological deformations, by introducing a novel overconnected geodesic vascular graph formulation, and without enforcing any anatomical prior constraint. The 3D elastic graph registration is then performed with state-of-the-art graph matching methods used in computer vision. Promising results of vascular matching are found using graphs from synthetic and real angiographies. Observations and future designs are discussed towards potential clinical applications.
A specific ovarian tumor protein isoform is required for efficient differentiation of germ cells in Drosophila oogenesis.

description: Mutations within the ovarian tumor (otu) gene result in abnormal ovarian development. It has been proposed that otu phenotypes result from abnormal germ cell division and differentiation. To understand better what role otu performs in oogenesis we have undertaken an analysis of protein expression from the otu locus. Anti-otu antibodies recognize two proteins from Drosophila ovary extracts with apparent molecular masses of 98 and 104 kD. Sequence analysis of otu cDNAs suggests that these proteins are translated from two mRNAs generated by alternative splicing of a 126-bp exon between the sixth and seventh exon of the smaller transcript. Analysis of otu protein expression in eight mutants indicates a correlation between the accumulation of the 104-kD isoform and predifferentiated germ cells and suggests that there is a developmental shift in the accumulation of the two isoforms upon differentiation of germ cells. Furthermore, the 104-kD isoform appears to be required for efficient differentiation of germ cells. Immunostaining of otu proteins is restricted to the cytoplasm of germ cells, and a rapid loss of oocyte immunostaining during stage 11 suggests that there is a rapid and selective degradation of otu proteins within the oocyte but not within its 15 interconnected nurse cells.

description: This paper presents a detailed study on the controlled experimental observation of drift wave instabilities in an inhomogeneous Six pole cusp magnetic field generated by an in-house developed Multi-pole line cusp magnetic field device (MPD) [Patel et al. Rev. Sci. Instrum., 44, 726 (2018)]. The device is composed of six axially symmetric cusps and non-cusp (in between two consecutive magnets) regions. The observed instability has been investigated in one of these non-cusp regions by controlling the radial plasma density gradient with changing pole magnetic field which is a unique feature of this device. It has been observed that the frequency of the instability changes explicitly with the density gradient. Moreover the scale length of plasma parameters, frequency spectrum, cross-correlation function, and fluctuation level of plasma densities has been measured in order to identify the instability. The cross field drift velocity due to fluctuation in plasma parameters have been measured from the wave number- frequency S (kz, ω) spectrum and verified with the theoretical values obtained from density scale length formula. Further from the S (kz, ω) spectrum it has been found that the drift velocity alternates the sign in the consecutive non-cusp regions.

The Kerr rotation noise spectroscopy at 4.2 K shows that the hole-capture probability of the In(Ga)As quantum dot is about one order of magnitude higher compared to the hole-capture probability of the ionized impurity and suggests that a simultaneous occupation of quantum dot and impurity by a hole is efficiently suppressed due to Coulomb interaction. A theoretical model of interconnected spin and charge noise allows the quantitative specification of all relevant time scales.

description: We consider the dynamical properties of simple edge states in integer ($ν= 1$) and fractional ($ ν= 1/2m+1$) quantum Hall (QH) liquids. The influence of a time-dependent local perturbation on the ground state is investigated. It is shown that the orthogonality catastrophe occurs for the initial and final state overlap $|| \sim L^{-{1\over{2ν}}({δ\overπ})^2}$ with the phase shift $δ$. The transition probability for the x-ray problem is also found with the index, dependent on $ν$. Optical experiments that measure the x-ray response of the QH edge are discussed. We also consider electrons tunneling from one dimensional Fermi liquid into a QH fluid. It is argued that for any filling fraction the tunneling from a Fermi liquid to the QH edge is suppressed at low temperatures and we find the nonlinear $I-V$ characteristics $I\sim V^{1/ν}$.

We proved in a previous paper that many of them can be realized as complete intersection singularities of “splice type,” generalizing Brieskorn type. We show that a normal singularity with homology sphere link is of splice type if and only if some naturally occurring knots in the singularity link are themselves links of hypersurface sections of the singular point. The Casson Invariant Conjecture (CIC) asserts that for a complete intersection surface singularity whose link is an integral homology sphere, the Casson invariant of that link is one-eighth the signature of the Milnor fiber. In this paper we prove CIC for a large class of splice type singularities. The CIC suggests (and is motivated by the idea) that the Milnor fiber of a complete intersection singularity with homology sphere link

description: We revisit the strong coupling limit of the Schwinger model on the lattice using staggered fermions and the hamiltonian approach to lattice gauge theories. Although staggered fermions have no continuous chiral symmetry, they posses a discrete axial invari ance which forbids fermion mass and which must be broken in order for the lattice Schwinger model to exhibit the features of the spectrum of the continuum theory. We show that this discrete symmetry is indeed broken spontaneously in the strong coupling li mit. Expanding around a gauge invariant ground state and carefully considering the normal ordering of the charge operator, we derive an improved strong coupling expansion and compute the masses of the low lying bosonic excitations as well as the chiral co ndensate of the model. We find very good agreement between our lattice calculations and known continuum values for these quantities already in the fourth order of strong coupling perturbation theory. We also find the exact ground state of the antiferromag netic Ising spin chain with long range Coulomb interaction, which determines the nature of the ground state in the strong coupling limit.

description: Presentation of machine learning (ML) model results plays an important role in decision makers’ trust and use. Yet, there has been little agreement on how information should be visualized to present models' evaluations. The purpose of this thesis is to formulate an approach to visualize the results of classification model’s evaluation to increase decision makers’ trust. This work proposes a dashboard that visualizes supervised ML model performance in a dashboard which is split into three main sections: statistical measures, feature importance, sensitivity analysis. Three sample dashboards were generated and evaluated using a survey by ten faculty members and students from George Mason University most of which said that the dashboard provides useful information and gives a better understanding of the model behavior than other methods they have experienced. Model evaluation strategies differ based on the prediction problem considered. However, a consistent representation of evaluation results may increase decision makers’ trust in the models. The next step of this project is to visualize the difference between multiple models.

description: We measure the correlation spectrum of the Hawking radiation emitted by an analogue black hole and find it to be thermal at the Hawking temperature implied by the analogue surface gravity. The Hawking radiation is in the regime of linear dispersion, in analogy with a real black hole. Furthermore, the radiation inside of the black hole is seen to be composed of negative-energy partners only. This work confirms the prediction of Hawking's theory regarding the value of the Hawking temperature, as well as the thermality of the spectrum. The thermality of Hawking radiation is the root of the information paradox. The correlations between the Hawking and partner particles imply that the analogue black hole has no analogue firewall.

title: Wrongful Convictions and Punitiveness: Measuring Student's Attitudes on Erroneous Felony Convictions
Creators: name: Lancaster, Shayna
Publisher: name: Old Dominion University Libraries
Year: 2011

description: The purpose of this study is to better understand the attitudes towards wrongful convictions and levels of punitiveness among college students who may work in the criminal justice field in the future. It attempts to replicate Robert Ramsey and James Frank's 2007 study "Wrongful Conviction - Perceptions of Criminal Justice Professionals Regarding the Frequency of Wrongful Conviction and the Extent of System Errors." Instead of surveying criminal justice professionals, this study's sample is on-campus undergraduate classes in criminal justice and political science for the spring 2010 semester at Old Dominion University using a survey that operationalizes punitiveness with a series of questions focused on retribution and incarceration.

Two hypotheses: Students planning on becoming defense attorneys will perceive wrongful felony convictions to occur less often than their professional counterparts and Students planning on becoming prosecutors will perceive system errors to occur less often than their professional counterparts, could not be tested by the current study. However, hypothesis one, "Students planning on becoming law enforcement officers will perceive system errors to occur less often than their professional counterparts", was not supported. Also, the findings of the current study suggest that political affiliation and class standing are the main predictors of level of punitiveness. The respondent's year in school (ex. freshman, sophomore, etc.) was found to significantly influence one's punitiveness: as education rises, level of punitiveness decreases.
Toward a Nordhaus-Gaddum Inequality for the Number of Dominating Sets

description: A dominating set in a graph $G$ is a set $S$ of vertices such that every vertex of $G$ is either in $S$ or is adjacent to a vertex in $S$. Nordhaus-Gaddum inequailties relate a graph $G$ to its complement $\bar{G}$. In this spirit Wagner proved that any graph $G$ on $n$ vertices satisfies $\partial(G)+\partial(\bar{G})\geq 2^n$ where $\partial(G)$ is the number of dominating sets in a graph $G$. In the same paper he comments that an upper bound for $\partial(G)+\partial(\bar{G})$ among all graphs on $n$ vertices seems to be much more difficult. Here we prove an upper bound on $\partial(G)+\partial(\bar{G})$ and prove that any graph maximizing this sum has minimum degree at least $\lfloor n/2\rfloor-2$ and maximum degree at most $\lfloor n/2\rfloor+1$. We conjecture that the complete balanced bipartite graph maximizes $\partial(G)+\partial(\bar{G})$ and have verified this computationally for all graphs on at most $10$ vertices.

description: We consider the effect of the transitions $n \to Δ^{0}$ and $p \to Δ^{+}$ in deep inelastic scattering on polarized $^3$He on the extraction of the neutron spin structure function $g_{1}^{n}(x,Q^2)$. Making the natural assumption that these transitions are the dominant non-nucleonic contributions to the renormalization of the axial vector coupling constant in the A=3 system, we find that the effect of $Δ$ increases $g_{1}^{n}(x,Q^2)$ by $10 ÷40$% in the range $0.05 \le x \le 0.6$, where our considerations are applicable and most of the data for $g_{1}^{n}(x,Q^2)$ exist.

Model-independent electroweak penguins in B decays to two pseudoscalars

description: We study the effects of electroweak penguin (EWP) amplitudes in $B$ meson decays into two charmless pseudoscalars in the approximation of retaining only the dominant EWP operators $Q_9$ and $Q_{10}$. Using flavor SU(3) symmetry, we derive a set of model-independent relations between EWP contributions and tree-level decay amplitudes one of which was noted recently by Neubert and Rosner. Two new applications of these relations are demonstrated in which uncertainties due to EWP corrections are eliminated in order to determine a weak phase. Whereas the weak angle $α$ can be obtained from $B\toππ$ free of hadronic uncertainties, a determination of $γ$ from $B^{0,\pm}\to Kπ^{\pm}$ requires the knowledge of a ratio of certain tree-level hadronic matrix elements. The smallness of this ratio implies a useful constraint on $γ$ if rescattering can be neglected.

description: We compute the effects of soft-gluon resummation, at the next-to-leading-logarithmic level, in the fixed-target hadroproduction cross section for prompt photons. We find in general that the corrections to the fixed next-to-leading-order results are large for large renormalization scales, and small for small scales. This leads to a significant reduction of the scale dependence of the results for most experimental configurations of interest. We compare our results to the recent measurements by the E706 and UA6 collaborations.

pretonic vowels
Brazilian Portuguese

description: We analyze dialect accommodation of pretonic midvowels /e/ and /o/ in the speech of 32 Northeastern migrants living in the Southeastern state of São Paulo/Brazil. Both vowels undergo lowering in Northeastern dialects (hɛ.ˈlɔ.ʒiw ‘watch’, hɔ.ˈmã ‘pomegranate’) but not in the Southeast (cf. he.ˈlɔ.ʒiw, ho.ˈmã). We thus analyzed whether these speakers, in accommodating to the host community’s dialect, tend to raise none, one or both vowels. Analyses of 1,916 tokens of /e/ (μF1 = 475Hz, sd = 47) and 1,645 tokens of /o/ (μF1 = 482Hz, sd = 51), extracted from sociolinguistic interviews, show that there’s a significant but weak correlation between the vowels’ height (Spearman’s rho = 0.38, p < 0.05), signaling uniformity in dialect accommodation. Further analyses of the individuals’ speech show that only half of them accommodated to either none or both vowels, and that accommodation to both vowels depends on speakers’ early arrival at the host community.
