NUCLEAR PHYSICS: Description of Chiral Doublet Bands in Odd-Odd Cs Isotopes  

NASA Astrophysics Data System (ADS)

Properties of the chair doublet bands of the odd-odd Cs isotopes built on the ?h11/2 otimesvh11/2 configuration are investigated systematically within the supersymmetry scheme including many-body interactions and possessing the SO(5)(or SU(5)) symmetry on the rotational symmetry. Quantitatively good results of the energy spectra, the energy staggering parameter as a function of the spin are obtained. The calculation shows that the stronger competition between the pairing and anti-pairing effects and the SU(3) symmetry broking more seriously exist in the stable chiral structure.

NUCLEAR PHYSICS: Some Electromagnetic Transition Properties of Odd-A Europium Isotopes  

NASA Astrophysics Data System (ADS)

In this work, we analyze the positive parity of states of odd-A Eu isotopes within the framework of interacting boson fermion model (IBFM-1). The result of an IBFM-1 multilevel calculation with the 3s1/2, 2d3/2, 2d5/2, and 1g7/2 single particle orbits is reported for the positive parity states of the odd-A Eu isotopes. Also, an IBM-1 calculation is presented for the low-lying states in the even-even 152-154Sm core nucleus. The energy levels and B(E2) transition probabilities are calculated and compared with the experimental data. It is found that the calculated positive parity low spin state energy spectra of the odd-A Eu isotopes agree quite well with the experimental data.

NUCLEAR PHYSICS: Description of Properties of Triaxial Superdeformed Bands in Odd-A Lu Isotopes  

NASA Astrophysics Data System (ADS)

Properties of the triaxial superdeformed (TSD) bands of odd-A Lu isotopes are investigated systematically within the supersymmetry scheme including many-body interactions and a perturbation possessing the SO(5) (or SU(5)) symmetry on the rotational symmetry. Quantitatively good results of the ?-ray energies, the dynamical moments of inertia and the spin of the TSD bands in odd-A Lu isotopes are obtained. The calculation shows that the competition between the pairing and anti-pairing effects exists in these TSD bands. Meanwhile, the SU(3) symmetry in TSD bands are broken more seriously than in superdeformed (SD) bands.

Odd Viscosity  

E-print Network

When time reversal is broken the viscosity tensor can have a non vanishing odd part. In two dimensions, and only then, such odd viscosity is compatible with isotropy. Allowing for odd viscosity leads to a generalization of the wave and Navier-Stokes equations. Elementary features of odd viscosity are examined by considering solutions of these equations for hypothetical fluids where the stress is dominated by odd viscosity. Introduction and summary of results: Normally, one associates viscosity with dissipation. However, since viscosity is, in general, a tensor, this need not always be the case. Breaking time reversal can lead to viscosity without dissipation, in the same way that it can lead to non-dissipating Hall conductance. The ordinary, dissipative viscosity is more important in liquids than is solids and then for small

A classification of spin frustration in molecular magnets from a physical study of large odd-numbered-metal, odd electron rings.  

PubMed

The term "frustration" in the context of magnetism was originally used by P. W. Anderson and quickly adopted for application to the description of spin glasses and later to very special lattice types, such as the kagomé. The original use of the term was to describe systems with competing antiferromagnetic interactions and is important in current condensed matter physics in areas such as the description of emergent magnetic monopoles in spin ice. Within molecular magnetism, at least two very different definitions of frustration are used. Here we report the synthesis and characterization of unusual nine-metal rings, using magnetic measurements and inelastic neutron scattering, supported by density functional theory calculations. These compounds show different electronic/magnetic structures caused by frustration, and the findings lead us to propose a classification for frustration within molecular magnets that encompasses and clarifies all previous definitions.

Even and Odd Nonlinear Negative Binomial States  

NASA Astrophysics Data System (ADS)

In this paper the even and odd nonlinear negative binomial states of the radiation field are introduced. These states interpolates between even (odd) number states and the even (odd) nonlinear coherent states. The Glauber second-order correlation function is calculated for these states. The squeezing phenomenon (normal and amplitude-squared squeezing), the quasi-probability distribution function Q-function, Wigner-function and the phase properties, are also discussed. Examination of the resonance fluorescence against the present state is given. It has been shown that the atomic inversion is sensitive to any variation in the even and odd nonlinear negative binomial number M and the nonlinearity parameter ?.

Exceptional Structures in the Odd-Odd Nucleus 250Md  

NASA Astrophysics Data System (ADS)

The low-energy two-quasiparticle bandhead energies for the odd-odd Z=101 nucleus 250Md are evaluated using a zero range residual neutron-proton interaction. The 250Md ground state is seen to have the spin-parity I?=0- corresponding to the singlet band from the configuration {p : 7/2[514]?n:7/2[624]} in violation of the Gallagher-Moszkowski (GM) coupling rule. The situation here is shown to be almost identical to that for the rare-earth nucleus 166Ho, which is the only well-established exception to the GM rule known so far. Analysis of the expected low energy spectrum, including the rotational levels, for 250Md reveals the occurrence of an as-yet-unobserved long-lived high-spin I? = 7- isomeric state around (80+/-30) keV with dominant ? and ? decay modes.

Extremal Myers-Perry Black Holes Coupled to Born-Infeld Electrodynamics in Odd Dimensions  

NASA Astrophysics Data System (ADS)

Employing higher-order perturbation theory, we find a new class of perturbative extremal rotating black hole solutions with Born-Infeld electric charge in odd D dimensional spacetime. The seed solution is an odd-dimensional extremal Myers-Perry black hole with equal angular momenta to which a perturbative, nonlinear, electric Born-Infeld field charge q is added maintaining the extremality condition. The perturbations are performed up to third-order. We also study some physical properties of these black holes. In particular, it is shown that the values of the gyromagnetic ratio of the black holes are modified by the perturbative parameter q and the Born-Infeld parameter ?.

Time-odd mean fields in covariant density functional theory: Rotating systems  

SciTech Connect

Time-odd mean fields (nuclear magnetism) and their impact on physical observables in rotating nuclei are studied in the framework of covariant density functional theory (CDFT). It is shown that they have profound effect on the dynamic and kinematic moments of inertia. Particle number, configuration, and rotational frequency dependencies of their impact on the moments of inertia have been analyzed in a systematic way. Nuclear magnetism can also considerably modify the band crossing features such as crossing frequencies and the properties of the kinematic and dynamic moments of inertia in the band crossing region. The impact of time-odd mean fields on the moments of inertia in the regions away from band crossing only weakly depends on the relativistic mean-field parametrization, reflecting good localization of the properties of time-odd mean fields in CDFT. The moments of inertia of normal-deformed nuclei considerably deviate from the rigid-body value. On the contrary, superdeformed and hyperdeformed nuclei have the moments of inertia which are close to rigid-body value. The structure of the currents in rotating frame, their microscopic origin, and the relations to the moments of inertia have been systematically analyzed. The phenomenon of signature separation in odd-odd nuclei, induced by time-odd mean fields, has been analyzed in detail.

Flavor Dependence of T-odd PDFs  

SciTech Connect

The flavor dependence of the naive time reversal odd ("T-odd'') parton distributions for $u$- and $d$-quarks are explored in the spectator model. The flavor dependence of $h_{1}^{\\perp}$ is of significance for the analysis of the azimuthal $\\cos(2\\phi)$ asymmetries in unpolarized SIDIS and DY-processes, as well as for the overall physical understanding of the distribution of transversely polarized quarks in unpolarized nucleons. As a by-product of the formalism, we calculate the chiral-odd but ``T-even'' function $h_{1L}^{\\perp}$ which enables us to present a prediction for the single spin asymmetry $A_{UL}^{\\sin(2\\phi)}$ for a longitudinally polarized target in SIDIS.

The Wigner caustic on shell and singularities of odd functions  

NASA Astrophysics Data System (ADS)

We study the Wigner caustic on shell of a Lagrangian submanifold L of affine symplectic space. We present the physical motivation for studying singularities of the Wigner caustic on shell and present its mathematical definition in terms of a generating family. Because such a generating family is an odd deformation of an odd function, we study simple singularities in the category of odd functions and their odd versal deformations, applying these results to classify the singularities of the Wigner caustic on shell, interpreting these singularities in terms of the local geometry of L.

Microscopic study of doublet bands in odd-odd A ? 100 nuclei  

NASA Astrophysics Data System (ADS)

A systematic study of the doublet bands observed in odd-odd mass ?100 is performed using the microscopic triaxial projected shell model approach. This mass region has depicted some novel features which are not observed in other mass regions, for instance, it has been observed that doublet bands cross diabatically in 106Ag. It is demonstrated that this unique feature is due to crossing of the two 2-quasiparticle configurations having different intrinsic structures. Further, we provide a complete set of transition probabilities for all the six-isotopes studied in this work and it is shown that the predicted transitions are in good agreement with the available experimental data.

Simultaneous Description of Even-Even, Odd-Mass and Odd-Odd Nuclear Spectra  

SciTech Connect

The orthosymplectic extension of the Interacting Vector Boson Model (IVBM) is used for the simultaneous description of the spectra of different families of neighboring heavy nuclei. The structure of even-even nuclei is used as a core on which the collective excitations of the neighboring odd-mass and odd-odd nuclei are built on. Hence, the spectra of the odd-mass and odd-odd nuclei arise as a result of the consequent and self-consistent coupling of the fermion degrees of freedom of the odd particles, specified by the fermion sector SO{sup F}(2OMEGA) subset of OS{sub p}(2OMEGA/12, R), to the boson core which states belong to an Sp{sup B}(12, R) irreducible representation.The theoretical predictions for different low-lying collective bands with positive and negative parity for two sets of neighboring nuclei with distinct collective properties are compared with experiment and IBM/IBFM/IBFFM predictions. The obtained results reveal the applicability of the used dynamical symmetry of the model.

We present for the first time, the nonadiabatic quasiparticle approach to study proton emission from odd-odd deformed nuclei. Coriolis effects are incorporated in both the parent and daughter wavefunctions and hence our formalism allows us to study their complete role on the decay widths. First results obtained for the nucleus {sup 112}Cs suggest a weak dependance on Coriolis effect. However, we are able to reproduce the experimental half-lives without assuming the exact Nilsson orbital from which the decay proceeds.

Time-odd mean fields in covariant density functional theory I. Non-rotating systems  

E-print Network

Time-odd mean fields (nuclear magnetism) are analyzed in the framework of covariant density functional theory (CDFT). It is shown that they always provide additional binding to the binding energies of odd-mass nuclei. This additional binding only weakly depends on the RMF parametrization reflecting good localization of the properties of time-odd mean fields in CDFT. The underlying microscopic mechanism is discussed in detail. Time-odd mean fields affect odd-even mass differences. However, our analysis suggests that the modifications of the strength of pairing correlations required to compensate for their effects are modest. In contrast, time-odd mean fields have profound effect on the properties of odd-proton nuclei in the vicinity of proton-drip line. Their presence can modify the half-lives of proton-emitters (by many orders of magnitude in light nuclei) and affect considerably the possibilities of their experimental observation.

Soil clay content underlies prion infection odds  

USGS Publications Warehouse

Environmental factors-especially soil properties-have been suggested as potentially important in the transmission of infectious prion diseases. Because binding to montmorillonite (an aluminosilicate clay mineral) or clay-enriched soils had been shown to enhance experimental prion transmissibility, we hypothesized that prion transmission among mule deer might also be enhanced in ranges with relatively high soil clay content. In this study, we report apparent influences of soil clay content on the odds of prion infection in free-ranging deer. Analysis of data from prion-infected deer herds in northern Colorado, USA, revealed that a 1% increase in the clay-sized particle content in soils within the approximate home range of an individual deer increased its odds of infection by up to 8.9%. Our findings suggest that soil clay content and related environmental properties deserve greater attention in assessing risks of prion disease outbreaks and prospects for their control in both natural and production settings. ?? 2011 Macmillan Publishers Limited.

We perform the perturbations up to 4th order for black holes in 5 dimensions and up to 3rd order in higher odd dimensions. We calculate the physical properties of these black holes and study their dependence on the charge and the dilaton coupling constant.

Observed parity-odd CMB temperature bispectrum  

NASA Astrophysics Data System (ADS)

Parity-odd non-Gaussianities create a variety of temperature bispectra in the cosmic microwave background (CMB), defined in the domain: l1 + l2 + l3 = odd. These models are yet unconstrained in the literature, that so far focused exclusively on the more common parity-even scenarios. In this work, we provide the first experimental constraints on parity-odd bispectrum signals in WMAP 9-year temperature data, using a separable modal parity-odd estimator. Comparing theoretical bispectrum templates to the observed bispectrum, we place constraints on the so-called nonlineality parameters of parity-odd tensor non-Gaussianities predicted by several Early Universe models. Our technique also generates a model-independent, smoothed reconstruction of the bispectrum of the data for parity-odd configurations.

Employing higher order perturbation theory, we obtain charged rotating black holes in odd dimensions, where the Einstein-Maxwell Lagrangian may be supplemented with a Chern-Simons term. Starting from the Myers-Perry solutions, we use the electric charge as the perturbative parameter and focus on extremal black holes with equal-magnitude angular momenta. For Einstein-Maxwell-Chern-Simons theory with arbitrary Chern-Simons coupling constant, we perform the perturbations up to 3rd order for any odd dimension. We discuss the physical properties of these black holes and study their dependence on the charge. In particular, we show that the gyromagnetic ratio g of Einstein-Maxwell black holes differs from the lowest order perturbative value D-2, and that the first correction term to g/(D-2) is universal.

Topology Explains Why Automobile Sunshades Fold Oddly  

ERIC Educational Resources Information Center

Automobile sunshades always fold into an "odd" number of loops. The explanation why involves elementary topology (braid theory and linking number, both explained in detail here with definitions and examples), and an elementary fact from algebra about symmetric group.

In the model, there is a fraction of privately informed bettors that maximize expected monetary payo¤s. For each market structure, the symmetric equilibria are characterized. In parimutuel betting, the return on longshots is driven to zero as the number of insiders grows large. In …xed odds betting instead, this return is bounded below.

A new interpretation for the even-odd effect in fission-fragments yields  

SciTech Connect

Calculations which describe the probability to break a pair on the way from saddle to scission point when the nucleus undergoes fission are presented. It is shown that they reproduce the main characteristics of the measured data on even-odd structure in fission-fragment yields. In particular, the strongly differing even-odd structures in proton and neutron numbers are explained within the assumption of thermal equilibrium of intrinsic excitations at scission.

Odd resistive response in superconductors with bianisotropic pinning  

NASA Astrophysics Data System (ADS)

A theoretical study is made of the odd resistive response (i.e., having odd parity with respect to inversion of the magnetic field) of a superconductor in the mixed state in the presence of bianisotropic pinning and a small isotropic Hall effect. The components of the odd magnetoresistivity in the directions longitudinal and transverse to the current are obtained in a two-dimensional stochastic model of bianisotropic pinning based on the Fokker-Planck equations in the approximation of noninteracting vortices and to a first approximation in the small Hall constant. Both naturally occurring and artificially produced realizations of this model are possible. It is shown that the nonlinear anisotropic properties of the magnetoresistivities are naturally related to the principal critical currents and saturation currents of the system under study. Scaling relations for the Hall conductivity in terms of the longitudinal and transverse magnetoresistivities obtained are discussed, and scaling and its stability in the basal X and Y geometries of the problem are examined.

Time-odd mean fields in covariant density functional theory: Nonrotating systems  

SciTech Connect

Time-odd mean fields (nuclear magnetism) are analyzed in the framework of covariant density functional theory (CDFT) by blocking the single-particle states with a fixed signature. It is shown that they always provide additional binding to the binding energies of odd-mass nuclei. This additional binding only weakly depends on the relativistic mean-field parametrization, reflecting good localization of the properties of time-odd mean fields in CDFT. The underlying microscopic mechanism is discussed in detail. Time-odd mean fields affect odd-even mass differences. However, our analysis suggests that the modifications of the strength of pairing correlations required to compensate for their effects are modest. In contrast, time-odd mean fields have a profound effect on the properties of odd-proton nuclei in the vicinity of the proton drip line. Their presence can modify the half-lives of proton emitters (by many orders of magnitude in light nuclei) and considerably affect the possibilities of their experimental observation.

Odd Parity Perturbations of the Self-Similar LTB Spacetime  

E-print Network

We consider the behaviour of odd-parity perturbations of those self-similar Lemaitre-Tolman-Bondi spacetimes which admit a naked singularity. We find that a perturbation which evolves from initially regular data remains finite on the Cauchy horizon. Finiteness is demonstrated by considering the behaviour of suitable energy norms of the perturbation (and pointwise values of these quantities) on natural spacelike hypersurfaces. This result holds for a general choice of initial data and initial data surface. Finally, we examine the perturbed Weyl scalars in order to provide a physical interpretation of our results. Our conclusions do not support the hypothesis of cosmic censorship.

Odd orders in Shor's factoring algorithm  

NASA Astrophysics Data System (ADS)

Shor's factoring algorithm (SFA) finds the prime factors of a number, $N=p_1 p_2$, exponentially faster than the best known classical algorithm. Responsible for the speed-up is a subroutine called the quantum order finding algorithm (QOFA) which calculates the order -- the smallest integer, $r$, satisfying $a^r \\mod N =1$, where $a$ is a randomly chosen integer coprime to $N$ (meaning their greatest common divisor is one, $\\gcd(a, N) =1$). Given $r$, and with probability not less than $1/2$, the factors are given by $p_1 = \\gcd (a^{\\frac{r}{2}} - 1, N)$ and $p_2 = \\gcd (a^{\\frac{r}{2}} + 1, N)$. For odd $r$ it is assumed the factors cannot be found (since $a^{\\frac{r}{2}}$ is not generally integer) and the QOFA is relaunched with a different value of $a$. But a recent paper [E. Martin-Lopez: Nat Photon {\\bf 6}, 773 (2012)] noted that the factors can sometimes be found from odd orders if the coprime is square. This raises the question of improving SFA's success probability by considering odd orders. We show that an improvement is possible, though it is small. We present two techniques for retrieving the order from apparently useless runs of the QOFA: not discarding odd orders; and looking out for new order finding relations in the case of failure. In terms of efficiency, using our techniques is equivalent to avoiding square coprimes and disregarding odd orders, which is simpler in practice. Even still, our techniques may be useful in the near future, while demonstrations are restricted to factoring small numbers. The most convincing demonstrations of the QOFA are those that return a non-power-of-two order, making odd orders that lead to the factors attractive to experimentalists.

CPT-Odd resonances in neutrino oscillations

We consider the consequences for future neutrino factory experiments of small CPT-odd interactions in neutrino oscillations. The nu(&mgr;)-->nu(&mgr;) and nu;(&mgr;)-->nu;(&mgr;) survival probabilities at a baseline L = 732 km can test for CPT-odd contributions at orders of magnitude better sensitivity than present neutrino sector limits. Interference between the CPT-violating interaction and CPT-even mass terms in the Lagrangian can lead to a resonant enhancement of the oscillation amplitude. For oscillations in matter, a simultaneous enhancement of both neutrino and antineutrino oscillation amplitudes is possible. PMID:11102185

Calculation of allowed and first-forbidden beta-decay transitions of odd-odd nuclei  

NASA Astrophysics Data System (ADS)

A method for calculating the ? -and{? +}/{EC} transitions from an odd-odd nucleus to the excited states of the adjacent even-even nucleus is presented. The beta transitions are treated combining the charge-conserving and the charge-changing mode of the quasi-particle random- phase approximation assuming a common vacuum. The beta-decay transitions are treated in their allowed and first-forbidden approximations, including also the ground-state transition. As a test case of the present formalism, detailed beta-decay properties of the following odd-odd-to-even-even transitions have been calculated and compared with experiment: the ?- decay transitions 136I(2 -)? 136Xe(J ?) and136Cs(5 +) ? 136Ba(J ?) , as well as the {? +}/{EC} transitions 136La(1 + ? 136Ba(J ?) . The calculated results agree nicely with data.

Stratospheric distributions of odd nitrogen and odd hydrogen in a two-dimensional model  

NASA Technical Reports Server (NTRS)

A two-dimensional pole-to-pole chemical model of the stratosphere is developed which extends from 8 to 38 km in altitude. Atmospheric motions are simulated by mean vertical and meridional winds and eddy diffusion coefficients. Seasonally averaged distributions of important odd nitrogen (NO, NO2, and HNO3) and odd hydrogen (H, OH, HO2, H2O2) compounds are computed. Photodissociation of N2O leads to production of odd nitrogen in the stratosphere, and the odd nitrogen is ultimately removed by downward transport into the troposphere and by rain-out (modeled by a rain-out lifetime of 30 days below 8-km altitude). Results are presented for a quasi-steady state in which seasonal cycles repeat themselves. These results show significant latitudinal as well as vertical variations in the predicted species which emphasize the need for at least two dimensions in accurate stratospheric modeling. Computed concentrations are compared with observations when they exist.

To supplement the already known classification of traces on classical pseudodifferential operators, we present a classification of traces on the algebras of odd-class pseudodifferential operators of non-positive order acting on smooth functions on a closed odd-dimensional manifold. By means of the one to one correspondence between continuous traces on Lie algebras and determinants on the associated regular Lie groups, we give a classification of determinants on the group associated to the algebra of odd-class pseudodifferential operators with fixed non-positive order. At the end we discuss two possible ways to extend the definition of a determinant outside a neighborhood of the identity on the Lie group associated to the algebra of odd-class pseudodifferential operators of order zero.

Specifically, there exists a geodesic in S and a parallel vertical plane field along it with constant vertical curvature and vanishing normal curvature. Under the added assumption that the Sharafutdinov fibers are rotationally symmetric, this implies that for small r, the distance sphere of radius r about S contains an immersed flat cylinder, and thus could not have positive curvature.

T-odd observables in elastic scattering, deep inelastic processes and weak decays  

NASA Astrophysics Data System (ADS)

We give a unitary description of T-odd effects in various sectors of atomic, nuclear and particle physics, like elastic scattering, deep inelastic processes and weak decays. This we get thanks to a particular transformation, which suggests a simple and unambiguous procedure for defining the two typical T-odd observables, the azimuthal asymmetry and the normal polarization. This approach allows to revise the two observables quite naturally in various situations, mainly in deep inelastic processes and in weak decays. In the latter case, useful suggestions for phenomenological analyses and an interesting result for normal and transverse polarization are derived.

Mothers' caries increases odds of children's caries.  

PubMed

There are many determinants of children's dental caries. We hypothesized that a mother's untreated caries was associated with increased likelihood of her children's untreated caries, after controlling for other factors. This population-based study was conducted in a rural, primarily Hispanic, California community. Interview and dental examination data for mother-child (children < 18 yrs old) dyads were analyzed. In a Generalized Estimation Equation (GEE) logit model for mothers (n = 179) and children (n = 387), maternal untreated caries was a statistically significant correlate of child's untreated caries, odds ratio (OR) = 1.76 (95%CI: 1.10, 2.70), adjusted for demographic factors. This relationship did not change when behavioral and dental utilization factors were added to the model, OR = 1.85 (95% CI: 1.12, 3.07). Maternal untreated caries almost doubled the odds of children's untreated caries and significantly increased child's caries severity by about 3 surfaces. Caries prevention and dental utilization programs for mothers and their children should be increased. PMID:20505046

The Euler current and parity odd transport  

E-print Network

For a spacetime of odd dimensions endowed with a unit vector field, we introduce a new topological current that is identically conserved and whose charge is equal to the Euler character of the even dimensional spacelike foliations. The existence of this current allows us to introduce new Chern-Simons-type terms in the effective field theories describing relativistic quantum Hall states and (2+1) dimensional superfluids. Using effective field theory, we calculate various correlation functions and identify transport coefficients. In the quantum Hall case, this current provides the natural relativistic generalization of the Wen-Zee term, required to characterize the shift and Hall viscosity in quantum Hall systems. For the superfluid case this term is required to have nonzero Hall viscosity and to describe superfluids with non s-wave pairing.

Even-odd effects in prompt emission in fission  

NASA Astrophysics Data System (ADS)

Compared to the extensively studied proton even-odd effects in fission fragment distributions, the even-odd effects in prompt emission received less attention. In this context the present paper is focusing on the even-odd effects (in both Z and N) appearing in prompt neutron and gamma ray emission. The study of even-odd effects in the prompt emission of four fissioning nuclei with even Z and even N, 233,235U(nth,f), 239Pu(nth,f) and 252Cf(SF), shows that these effects are mainly due to the Z even-odd effects in fragment distributions and charge deviations and the N even-odd effect in average neutron separation energies. The most pronounced even-odd effect in prompt emission is for the prompt neutron multiplicity. The average multiplicity as a function of Z, ?(Z), has a sawtooth shape and exhibits a visible staggering for asymmetric fragmentations. The size of the global even-odd effect in prompt neutron multiplicity shows a decrease with increasing fissility. The N even-odd effect in average neutron separation energy influences the global even-odd effect in prompt neutron multiplicity often in an opposite way compared to the Z even-odd effect. The average prompt neutron multiplicity as a function of TKE shows an increase of the Z even-odd effect with increasing TKE and this effect is decreasing for heavier fissioning systems. The Z even-odd effects in the average prompt ?-ray energy and the average prompt neutron energy have comparable sizes and are lower than the even-odd effects in prompt neutron multiplicity. Different average prompt emission quantities (as a function of A, of Z, of TKE and total average ones)-being dependent on fragment distributions-are affected by the even-odd effects in Y(A,Z,TKE). The N even-odd effect in neutron separation energy and the Z even-odd effect in the charge deviation enter the primary multi-parametric matrices of prompt emission quantities (e.g. ?(A,Z,TKE)) which are not depending on fragment distributions.

Genuine CP-odd Observables at the LHC  

E-print Network

We discuss how to construct genuine CP-odd observables at the LHC. We classify the observables according to the even and odd properties under the naive T-transformation (\\hat{T}). There are two classes of observables of our interests: CP-odd and \\hat{T}-even; CP-odd and \\hat{T}-odd. We expect them to have broad applications to many processes in theories beyond Standard Model with CP violation. For the purpose of illustration, we use simple example of W+W- production and subsequent decays at the LHC, where the CP violation effects are parameterized by effective CP-violating operators of WWZ coupling. We find significant sensitivity to the CP-odd couplings.

The distributions of odd nitrogen and odd hydrogen in the natural and perturbed stratosphere  

NASA Technical Reports Server (NTRS)

In order to quantitatively illustrate the effects of quasi-horizontal transport of certain gases and of the reactions influencing their concentrations, a vertical-meridional pole-to-pole stratospheric model is presented which explicitly predicts concentrations of odd nitrogen and odd hydrogen compounds in the natural stratosphere and also in a perturbed stratosphere incorporating artificial injection of nitrogen oxides by an SST fleet. The northern hemisphere SST operations clearly have a very large local effect on the nitrogen oxide distribution and also have a significant effect on the southern hemisphere. The largest changes are seen at the point of injection of the nitrogen oxides. Results are in agreement with previous one-dimensional models.

Lifetime measurements for some states of the positive-parity sequence using the Doppler shift attenuation method revealed transition strengths of [ital B]([ital E]2)[approx]40 Weisskopf units. Thus, this band is interpreted as a collective structure built on the two-quasiparticle intruder configuration ([pi][ital g][sub 9/2][direct product][nu][ital g][sub 9/2]).

Two multi-quasiparticle structures have been extended significantly from spin {approx}20{h_bar} to above 40{h_bar}. As a result, the first rotational alignment has been fully delineated and a second band crossing has been observed for the first time in this nucleus. Configurations for these strongly coupled rotational bands are proposed based on signature splitting, B(M1)/B(E2) ratio information, and observed rotation-alignment behavior. Properties of the observed bands in {sup 168}Ta are compared to related structures in the neighboring odd-Z, odd-N, and odd-odd nuclei and are discussed within the framework of the cranked shell model.

The Geometry of Statistical Models for Two-Way Contingency Tables with Fixed Odds Ratios  

Microsoft Academic Search

We study the geometric structure of the statistical models for two-by-two contingency tables. One or two odds ratios are fixed and the corresponding models are shown to be a portion of a ruled quadratic surface or a segment. Some pointers to the general case of two-way contingency tables are also given and an application to case-control studies is presented.

The odd–even effect of fragmentation cross sections for 36Ar and 40Ar  

NASA Astrophysics Data System (ADS)

Projectile fragmentation cross sections are calculated for reactions of 36Ar and 40Ar on C, Al, Cu, and Pb targets at 400 A MeV by using the improved quantum molecular dynamics model, together with the statistical model code GEMINI. The total cross sections increase with increasing target mass, which is in good agreement with the experimental results and other theoretical predictions. The isotopic distributions and isospin distributions suggest that the odd–even effect is dependent on the projectile nuclei. For a 36Ar projectile with {{T}Z}=0, the partial cross sections appear an obvious odd–even effect, and the isotopic distributions show that the maximal cross sections for the even-Z isotope are larger than that for the neighboring odd-Z isotope. However, the fragmentation cross sections and the isotopic distributions for the 40Ar projectile have not shown these characteristics. The isospin distributions show that the odd–even effect of fragments from the {{T}Z}=0 projectile is stronger than that from the {{T}Z}=-2 projectile.

An investigation of the solar cycle response of odd-nitrogen in the thermosphere  

NASA Technical Reports Server (NTRS)

This annual report covers the first year of funding for the study of the solar cycle variations of odd-nitrogen (N((sup 2)D), N((sup 4)S), NO) in the Earth's thermosphere. The study uses the extensive data base generated by the Atmosphere Explorer (AE) satellites, and the Solar Mesosphere Explorer Satellite. The AE data are being used, for the first time, to define the solar variability effect on the odd-nitrogen species through analysis of the emissions at 520 nano-m from N((sup 2)D) and the emission from O(+)((sup 2)P). Additional AE neutral and ion density data are used to help define and quantify the physical processes controlling the variations. The results from the airglow study will be used in the next two years of this study to explain the solar cycle changes in NO measured by the Solar Mesosphere Explorer.

Tell Me the Odds (of Cancer)  

NSDL National Science Digital Library

Through four lessons and three hands-on activities, students learn the concepts of refraction and interference in order to solve an engineering challenge: "In 2013, actress Angelina Jolie underwent a double mastectomy, not because she had been diagnosed with breast cancer, but merely to lower her cancer risk. But what if she never inherited the gene(s) that are linked to breast cancer and endured surgery unnecessarily? Can we create a new method of assessing people's genetic risks of breast cancer that is both efficient and cost-effective?" While pursuing a solution to this challenge, students learn about some high-tech materials and delve into the properties of light, including the equations of refraction (index of refraction, Snell's law). Students ultimately propose a method to detect cancer-causing genes by applying the refraction of light in a porous film in the form of an optical biosensor. Investigating this challenge question through this unit is designed for an honors or AP level physics class, although it could be modified for conceptual physics.

Interventions shown to Aid Executive Function Development in Children 4–12 Years Old *

To be successful takes creativity, flexibility, self-control, and discipline. Central to all those are ‘executive functions,’ including mentally playing with ideas, giving a considered rather than an impulsive response, and staying focused. Diverse activities have been shown to improve children’s executive functions – computerized training, non-computerized games, aerobics, martial arts, yoga, mindfulness, and school curricula. Central to all these is repeated practice and constantly challenging executive functions. Children with worse executive functions initially, benefit most; thus early executive-function training may avert widening achievement gaps later. To improve executive functions, focusing narrowly on them may not be as effective as also addressing emotional and social development (as do curricula that improve executive functions) and physical development (shown by positive effects of aerobics, martial arts, and yoga).

Odd cloud in the Ross Sea, Antarctica  

NASA Technical Reports Server (NTRS)

On January 28, 2002, MODIS captured this image of an interesting cloud formation in the boundary waters between Antarctica's Ross Sea and the Southern Ocean. A dragon? A snake? A fish? No, but it is an interesting example of the atmospheric physics of convection. The 'eye' of this dragon-looking cloud is likely a small spot of convection, the process by which hot moist air rises up into the atmosphere, often producing big, fluffy clouds as moisture in the air condenses as rises into the colder parts of the atmosphere. A false color analysis that shows different kinds of clouds in different colors reveals that the eye is composed of ice crystals while the 'body' is a liquid water cloud. This suggests that the eye is higher up in the atmosphere than the body. The most likely explanation for the eye feature is that the warm, rising air mass had enough buoyancy to punch through the liquid water cloud. As a convective parcel of air rises into the atmosphere, it pushes the colder air that is higher up out of its way. That cold air spills down over the sides of the convective air mass, and in this case has cleared away part of the liquid cloud layer below in the process. This spilling over of cold air from higher up in the atmosphere is the reason why thunderstorms are often accompanied by a cool breeze.

A flower-like structure composed of four electrically small split-ring resonators (SRRs) arranged in a cruciate pattern, each with a maximum dimension of less than ?o/10, is shown to achieve more than 43% microwave-to-alternating current conversion efficiency at 5.67 GHz. Even- and odd-mode currents are realized in the proposed harvester to improve the efficiency and concurrently reduce the dielectric loss in the substrate. An experimental validation is conducted to prove the harvesting capability.

Use of prior odds for missing persons identifications  

PubMed Central

Identification of missing persons from mass disasters is based on evaluation of a number of variables and observations regarding the combination of features derived from these variables. DNA typing now is playing a more prominent role in the identification of human remains, and particularly so for highly decomposed and fragmented remains. The strength of genetic associations, by either direct or kinship analyses, is often quantified by calculating a likelihood ratio. The likelihood ratio can be multiplied by prior odds based on nongenetic evidence to calculate the posterior odds, that is, by applying Bayes' Theorem, to arrive at a probability of identity. For the identification of human remains, the path creating the set and intersection of variables that contribute to the prior odds needs to be appreciated and well defined. Other than considering the total number of missing persons, the forensic DNA community has been silent on specifying the elements of prior odds computations. The variables include the number of missing individuals, eyewitness accounts, anthropological features, demographics and other identifying characteristics. The assumptions, supporting data and reasoning that are used to establish a prior probability that will be combined with the genetic data need to be considered and justified. Otherwise, data may be unintentionally or intentionally manipulated to achieve a probability of identity that cannot be supported and can thus misrepresent the uncertainty with associations. The forensic DNA community needs to develop guidelines for objectively computing prior odds. PMID:21707977

Discrimination between roles of fissioning nucleus and asymmetry degree of freedom on the even-odd structure in fission-fragment yields  

E-print Network

Based on a wide systematics of fission-fragment distributions measured in low-energy fission, the even-odd staggering in the fission-fragment element yields is investigated. The well-established evolution of the global even-odd effect with the fissioning system is found to be only a partial aspect of the even-odd structure. Indeed, it is shown that the global even-odd effect is varying systematically with the mean asymmetry of the fission-fragment distribution, and that the general increase of the even-odd staggering with asymmetry is depending on the fissioning system. Thus, the dependency of the even-odd effect with the fissioning system is accredited in part to the asymmetry evolution of the charge distribution, and not solely related to the dissipated energy as it has been done earlier. This interpretation is strongly supported by data measured in inverse kinematics, which cover the complete charge distribution and include precise yields at symmetry. The relevance of the order parameter to describe the even-odd effect in fission-fragment yields as a general property is explored.

Electromagnetic and thermal responses of Z topological insulators and superconductors in odd spatial dimensions.  

PubMed

The relation between bulk topological invariants and experimentally observable physical quantities is a fundamental property of topological insulators and superconductors. In the case of chiral symmetric systems in odd spatial dimensions such as time-reversal invariant topological superconductors and topological insulators with sublattice symmetry, this relation has not been well understood. We clarify that the winding number which characterizes the bulk Z nontriviality of these systems can appear in electromagnetic and thermal responses in a certain class of heterostructure systems. It is also found that the Z nontriviality can be detected in the bulk "chiral polarization," which is induced by magnetoelectric effects. PMID:25166392

Equivalences of classifying spaces completed at odd primes  

NASA Astrophysics Data System (ADS)

We prove the Martino-Priddy conjecture for an odd prime p: the p-completions of the classifying spaces of two groups G and G(') are homotopy equivalent if and only if there is an isomorphism between their Sylow p-subgroups which preserves fusion. A second theorem is a description for odd p of the group of homotopy classes of self homotopy equivalences of the p-completion of BG, in terms of automorphisms of a Sylow p-subgroup of G which preserve fusion in G. These are both consequences of a technical algebraic result, which says that for an odd prime p and a finite group G, all higher derived functors of the inverse limit vanish for a certain functor calz_G on the p-subgroup orbit category of G.

A loop group extension of the odd Chern character.  

E-print Network

We show that the universal odd Chern form, defined on the stable unitary group $U$, extends to the loop group $LU$ in a way that is closed with respect to an equivariant-type differential. This provides an odd analogue to the Bismut-Chern form. We also describe the associated transgression form, the so-called Bismut-Chern-Simons form, and explicate some properties it inherits as a differential form on the space of maps of a cylinder into the stable unitary group. As a corollary, we obtain the Chern character homomorphism from odd K-theory to the periodic cohomology of the free loop space, represented geometrically on the level of differential forms.

Global phenomenological descriptions of nuclear odd-even mass staggering  

E-print Network

We examine the general nature of nuclear odd-even mass differences by employing neutron and proton mass relations that emphasize these effects. The most recent mass tables are used. The possibility of a neutron excess dependence of the staggering is examined in detail in separate regions defined by the main nuclear shells, and a clear change in this dependency is found at $Z=50$ for both neutrons and protons. A further separation into odd and even neutron (proton) number produces very accurate local descriptions of the mass differences for each type of nucleons. These odd-even effects are combined into a global phenomenological expression, ready to use in a binding energy formula. The results deviate from previous parametrizations, and in particular found to be significantly superior to a recent two term, $A^{-1}$ dependence.

Age and sex differences in physical inactivity among Ontario teenagers.  

PubMed

Research on physical activity and fitness indicates their importance in the prevention of disease and promotion of health. However, levels of physical activity have been shown to vary significantly by age, sex and a wide range of additional factors. This paper examines age and sex differences in physical inactivity among 13 to 19 year olds participating in the 1990 Ontario Health Survey. Findings from the bivariate analysis suggest a major increase in physical inactivity between ages 15 and 16. When logistic regression is used to examine the adjusted effects of predictor variables on physical inactivity, the effects of age remain significant. However, the odds of inactivity at one year increments are not significant. There are significant increased odds of inactivity associated with such factors as sex, friends' (activity) participation, perceived future health problems, and perceived health status. The public health implications of the findings suggest that those responsible for developing programs and policies to increase physical activity among teenagers should consider the critical years of decreased activity and the factors that might explain why this decline occurs.

Photochemical calculations along 'diabatic trajectories' in the meridional phase are used to search for the cause of the dramatic springtime minimum in Antarctic column ozone. The results indicate that the minimum is principally due to catalytic destruction of ozone by high levels of total odd nitrogen. Calculations suggest that these levels of odd nitrogen are transported within the polar vortex and during the polar night from the middle to upper stratosphere and lower mesosphere to the lower stratosphere. The possibility that these levels are related to the 11-year solar cycle and are increased by enhanced formation in the thermosphere and mesosphere during solar maximum conditions is discussed.

CP-odd phase correlations and electric dipole moments  

SciTech Connect

We revisit the constraints imposed by electric dipole moments (EDMs) of nucleons and heavy atoms on new CP-violating sources within supersymmetric theories. We point out that certain two-loop renormalization group corrections induce significant mixing between the basis-invariant CP-odd phases. In the framework of the constrained minimal supersymmetric standard model, the CP-odd invariant related to the soft trilinear A-phase at the grand unified theory (GUT) scale, {theta}{sub A}, induces nontrivial and distinct CP-odd phases for the three gaugino masses at the weak scale. The latter give one-loop contributions to EDMs enhanced by tan{beta}, and can provide the dominant contribution to the electron EDM induced by {theta}{sub A}. We perform a detailed analysis of the EDM constraints within the constrained minimal supersymmetric standard model, exhibiting the reach, in terms of sparticle spectra, which may be obtained assuming generic phases, as well as the limits on the CP-odd phases for some specific parameter points where detailed phenomenological studies are available. We also illustrate how this reach will expand with results from the next generation of experiments which are currently in development.

We study the modularity properties of these secondary characteristic forms and relations among them. We also get some twisted anomaly cancellation formulas on some odd dimensional manifolds.

Alignments, additivity, and signature inversion in odd-odd {sup 170}Ta: A comprehensive high-spin study  

SciTech Connect

High-spin states (I < or approx. 50(Planck constant/2pi)) of the odd-odd nucleus {sup 170}Ta have been investigated with the {sup 124}Sn({sup 51}V,5n) reaction. The resolving power of Gammasphere has allowed for the observation of eleven rotational bands (eight of which are new) and over 430 transitions (approx350 of which are new) in this nucleus. Many interband transitions have been observed such that the relative spins and excitation energies of the 11 bands have been established. This is an unusual circumstance in an odd-odd study. Configurations have been assigned to most of these bands based upon features such as alignment properties, band crossings, B(M1)/B(E2) ratios, and the additivity of Routhians. A systematic study of the frequency at which normal signature ordering occurs in the pih{sub 9/2}nui{sub 13/2} band has been performed and it is found that its trend is opposite to that observed in the pih{sub 11/2}nui{sub 13/2} bands. A possible interpretation of these trends is discussed based on a proton-neutron interaction.

Type of Diabetes Mellitus and the Odds of Gleason Score 8 to 10 Prostate Cancer  

SciTech Connect

Purpose: It has been recently shown that diabetes mellitus (DM) is significantly associated with the likelihood of presenting with high-grade prostate cancer (PCa) or Gleason score (GS) 8 to 10; however, whether this association holds for both Type 1 and 2 DM is unknown. In this study we evaluated whether DM Type 1, 2, or both are associated with high-grade PCa after adjusting for known predictors of high-grade disease. Methods and Materials: Between 1991 and 2010, a total of 15,330 men diagnosed with PCa and treated with radiation therapy were analyzed. A polychotomous logistic regression analysis was performed to evaluate whether Type 1 or 2 DM was associated with odds of GS 7 or GS 8 to 10 compared with 6 or lower PCa, adjusting for African American race, age, prostate-specific antigen (PSA) level, and digital rectal examination findings. Results: Men with Type 1 DM (adjusted odds ratio [AOR], 2.05; 95% confidence interval [CI], 1.28-3.27; p = 0.003) or Type 2 DM (AOR, 1.58; 95% CI, 1.26-1.99; p < 0.001) were significantly more likely to be diagnosed with GS 8 to 10 PCa compared with nondiabetic men. However this was not true for GS 7, for which these respective results were AOR, 1.30; 95% CI, 0.93-1.82; p = 0.12 and AOR, 1.13; 95% CI, 0.98-1.32; p = 0.10. Conclusion: Type 1 and 2 DM were associated with a higher odds of being diagnosed with Gleason score 8 to 10 but not 7 PCa. Pending validation, men who are diagnosed with Type I DM with GS 7 or lower should be considered for additional workup to rule out occult high-grade disease.

Level density and ?-ray strength function in the odd-odd Np238 nucleus  

NASA Astrophysics Data System (ADS)

The level density and ?-ray strength function in the quasicontinuum of Np238 have been measured using the Oslo method. The level-density function follows closely the constant-temperature level-density formula and reaches 43×106 levels per MeV at Sn=5.488 MeV of excitation energy. The ?-ray strength function displays a two-humped resonance at low-energy as also seen in previous investigations of Th, Pa, and U isotopes. The structure is interpreted as the scissors resonance and has an average centroid of ?SR=2.26(5) MeV and a total strength of BSR=10.8(12)?N2, which is in excellent agreement with sum-rule estimates. The scissors resonance is shown to have an impact on the Np237(n ,?)238Np cross section.

Shape phase transitions in odd-A nuclei  

SciTech Connect

We investigate shape phase transitions in odd nuclei within the Interacting Boson Fermion Model. Special attention is given to the case of the transition from the vibrational behaviour to the stable axial deformation. The odd particle is assumed to be moving in the three single particle orbitals j = 1/2,3/2,5/2 with a boson-fermion Hamiltonian that leads to the occurrence of the SU{sup BF}(3) boson-fermion symmetry when the boson part approaches the SU(3) condition. Both energy spectra and electromagnetic transitions show characteristic patterns similar to those displayed by the even nuclei at the corresponding critical point. The role of the additional particle in characterizing the properties of the critical points in finite quantal systems is investigated by resorting to the formalism based on the intrinsic frame.

[Translation of the English term odds ratio as oportunidad relativa].

In the present work we argue for the translation of the English term odds ratio, a term of formal anti-natural esthetics for the Spanish-speaking and with added phonetic difficulties, for oportunidad relativa. These words respect the English abbreviation OR facilitating the expression of consistent formulations which may be directly translated, as well as communication between users, since the linguistic confusion due to the present abundance of terms used in Spanish, is reduced to one. Our justifications are mainly syntactic and semantic and reflect reasonable comparability between the terms odds ratio and oportunidad relativa. Reviews of some of the most prestigious dictionaries of the English and the Spanish languages lend additional support to our proposition. PMID:9092101

Odd-frequency triplet pairing in mixed-parity superconductors  

NASA Astrophysics Data System (ADS)

We show that mixed-parity superconductors may exhibit equal-spin pair correlations that are odd-in-time and can be tuned by means of an applied field. The direction and the amplitude of the pair correlator in the spin space turn out to be strongly dependent on the symmetry of the order parameter, and thus provide a tool to identify different types of singlet-triplet mixed configurations. We suggest that odd-in-time spin-polarized pair correlations can be generated without magnetic inhomogeneities in superconducting/ferromagnetic hybrids with non-centrosymmetric superconductor or when parity mixing is induced at the interface.

Mesospheric Odd Nitrogen Enhancements During Relativistic Electron Precipitation Events  

NASA Technical Reports Server (NTRS)

The behavior of mesospheric odd nitrogen species during and following relativistic and diffuse auroral precipitation events is simulated, Below 75 km nitric oxide is enhanced in proportion to the ion pair production function associated with the electron precipitation and the length of the event. Nitrogen dioxide and nitric acid are also enhanced. At 65 km the percentage of odd nitrogen for N is 0.1%, HNO3 is 1.6%, NO2 is 15%, and NO is 83.3%. Between 75 and 85 km NO is depleted during particle events due to the faster destruction of NO by N relative to the production of NO by N reacting with O2. Recovery of NO depends on transport from the lower thermosphere, where NO is produced in abundant amounts during particle events.

Fermions in Odd Space-Time Dimensions: Back to Basics

It is a well-known feature of odd space-time dimensions d that there exist two inequivalent fundamental representations A and B of the Dirac gamma matrices. Moreover, the parity transformation swaps the fermion fields living in A and B. As a consequence, a parity-invariant Lagrangian can only be constructed by incorporating both the representations.

(abstract) Odd Hydrogen in the Atmospheres of Earth and Mars  

NASA Technical Reports Server (NTRS)

The Martian atmosphere has many features in common with the terrestrial mesosphere. Both share similar pressure and temperature ranges, and much of the same chemistry operates in each. For example, the radical species H, OH, and H(sub 2)O, which comprise the odd hydrogen family, are of central importance in the catalytic destruction of CO and O(sub 3) in both atmospheres. The inclusion of recent chemical kinetics data, specifically temperature dependent CO(sub 2) absorption cross-sections, into our one dimensional photochemical model of the Martial atmosphere shows that oxidation of CO by odd hydrogen is too efficient. The incorporation of smaller cross sections for CO(sub 2) leads to an enhanced photolysis rate of water vapor, increasing odd hydrogen to the point where the predicted mixing ratio of CO in our model is substantially less than the observed value of 6.5 x 10(sup -4). Interestingly, most photochemical models of the terrestrial mesosphere underestimate the CO and O(sub 3) densities using currently accepted photodissociation and kinetic rate coefficients. This has also been attributed to an overabundance of odd hydrogen in the models. We shall show that agreement between models and observations of CO in the Martian atmosphere as well as of CO and O(sub 3) in the terrestrial mesosphere can be achieved by revising the rate constants for the reactions OH + HO(sub 2) and CO + OH within their published uncertainties. The fact that similar revisions alleviate discrepancies in both the terrestrial and Martian atmospheres warrants a re-evaluation of these key rate constants at the appropriate temperatures and pressures.

Semiparametric Efficient Estimation for a Class of Generalized Proportional Odds Cure Models.  

PubMed

We present a mixture cure model with the survival time of the "uncured" group coming from a class of linear transformation models, which is an extension of the proportional odds model. This class of model, first proposed by Dabrowska and Doksum (1988), which we term "generalized proportional odds model," is well suited for the mixture cure model setting due to a clear separation between long-term and short-term effects. A standard expectation-maximization algorithm can be employed to locate the nonparametric maximum likelihood estimators, which are shown to be consistent and semiparametric efficient. However, there are difficulties in the M-step due to the nonparametric component. We overcome these difficulties by proposing two different algorithms. The first is to employ an majorize-minimize (MM) algorithm in the M-step instead of the usual Newton-Raphson method, and the other is based on an alternative form to express the model as a proportional hazards frailty model. The two new algorithms are compared in a simulation study with an existing estimating equation approach by Lu and Ying (2004). The MM algorithm provides both computational stability and efficiency. A case study of leukemia data is conducted to illustrate the proposed procedures. PMID:22865944

Single-particle structures, high-spin isomers, and a strongly coupled band in odd-odd Sb120

Excited states in Sb120 have been investigated using the Cd116(Li7,3n)Sb120 reaction at a beam energy of 34 MeV. A total of 15 new ? rays were added into the level scheme of Sb120. Most of the observed single-particle states can be interpreted in terms of weak coupling of the odd proton and odd neutron to an excited Sn118 core involving either vibrational states or broken neutron pairs. The previously known strongly coupled rotational band based on the ?g9/2-1??h11/2 configuration has been extended up to the (15-) state. The configuration-fixed constrained triaxial relativistic mean-field approaches and the particle rotor model are employed to discuss the high-spin isomers and strongly coupled rotational band, respectively.

Solar Cycle Dependence Of Temperature, Odd-Oxygen, Odd-Hydrogen, And Airglow In The Mesopause Region Observed By SABER  

NASA Astrophysics Data System (ADS)

We present the first consistent, global set of temperature, pressure, odd-oxygen, odd-hydrogen and airglow measurements in the mesopause region spanning a complete solar cycle. The measurements are derived from the Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) instrument on the NASA TIMED satellite. These data clearly indicate the influence of solar variability on the atmosphere structure and composition. In general, the values of most parameters decrease with decreasing solar activity. However, odd-hydrogen is observed to increase with decreasing solar activity. While the data indicate a direct relation between solar activity and atmospheric response, the role of dynamical variability in modulating the direct solar response has not yet been investigated, particularly on regional scales (e.g.,tropical, mid-latitude, or polar). We describe the SABER observations in detail and discuss how they can be used with general circulation models to assess the coupled role of dynamics and solar variability in determining the overall atmospheric response.

Multi-quasiparticle structures up to spin {approx}44({h_bar}/2{pi}) in the odd-odd nucleus {sup 168}Ta  

SciTech Connect

High-spin states in the odd-odd nucleus {sup 168}Ta have been populated in the {sup 120}Sn({sup 51}V,3n) reaction. Two multi-quasiparticle structures have been extended significantly from spin {approx}20({h_bar}/2{pi}) to above 40({h_bar}/2{pi}). As a result, the first rotational alignment has been fully delineated and a second band crossing has been observed for the first time in this nucleus. Configurations for these strongly coupled rotational bands are proposed based on signature splitting, B(M1)/B(E2) ratio information, and observed rotation-alignment behavior. Properties of the observed bands in {sup 168}Ta are compared to related structures in the neighboring odd-Z, odd-N, and odd-odd nuclei and are discussed within the framework of the cranked shell model.

Collective gyromagnetic ratios and the structure of odd superdeformed A=190 nuclei  

SciTech Connect

Collective gyromagnetic ratios g{sub R}, microscopically calculated from Hartree-Fock plus BCS calculations using the SkM{sup {asterisk}} force, are found to be very different from the rough Z/A estimates. It is pointed out that the latter disagree with the spectroscopic data in normally deformed states of even-even nuclei. The consequences of taking into account microscopic values of g{sub R} on the spectroscopic properties of odd superdeformed A=190 nuclei are discussed. Quenching factors, for proton and neutron g{sub s} ratios, are tentatively proposed. Single-particle assignments postulated by experimentalists for the available data are confirmed by our consistent approach. {copyright} {ital 1997} {ital The American Physical Society}

QCD evolution of naive-time-reversal-odd fragmentation functions  

SciTech Connect

We study QCD evolution equations of the first transverse-momentum moment of the naive-time-reversal-odd fragmentation functions--the Collins function and the polarizing fragmentation function. We find for the Collins function case that the evolution kernel has a diagonal piece the same as that for the transversity fragmentation function, while for the polarizing fragmentation function case this piece is the same as that for the unpolarized fragmentation function. Our results might have important implications in the current global analysis of spin asymmetries.

Asymmetry between odd and even node weight in complex networks  

NASA Astrophysics Data System (ADS)

Phenomenon of asymmetry between odd and even node weight distribution in some complex networks, such as public transportation networks and Internet, is presented. Reasons related to this phenomenon are summarized, i.e., (1) edges are solid connections between nodes which are embedded in real geometric background, and (2) preferential mechanism during the process of network formation. Incorporating these two points, complex networks are constructed by self-avoiding random walk on 2D grid and the simulation results are consistent well with that of empirical researches.

On doubly robust estimation in a semiparametric odds ratio model.  

PubMed

We consider the doubly robust estimation of the parameters in a semiparametric conditional odds ratio model. Our estimators are consistent and asymptotically normal in a union model that assumes either of two variation independent baseline functions is correctly modelled but not necessarily both. Furthermore, when either outcome has finite support, our estimators are semiparametric efficient in the union model at the intersection submodel where both nuisance functions models are correct. For general outcomes, we obtain doubly robust estimators that are nearly efficient at the intersection submodel. Our methods are easy to implement as they do not require the use of the alternating conditional expectations algorithm of Chen (2007). PMID:23049119

On higher twist chiral-odd pion generalized parton distributions  

E-print Network

We define in the framework of light-cone collinear factorization method, the chiral-odd generalized parton distributions (GPDs) of a pseudoscalar hadron (such as the $\\pi^0$) up to twist 6. For that, we introduce the relevant matrix elements for 2-parton non-local operators, as well as matrix elements for 3-parton non-local correlators. Their detailed parametrization is fixed based on parity, charge conjugation and time reversal invariance. This leads to the introduction of 28 real GPDs, which are subject to constraints coming from the QCD equations of motion.

Mothers’ Caries Increases Odds of Children’s Caries  

PubMed Central

There are many determinants of children’s dental caries. We hypothesized that a mother’s untreated caries was associated with increased likelihood of her children’s untreated caries, after controlling for other factors. This population-based study was conducted in a rural, primarily Hispanic, California community. Interview and dental examination data for mother-child (children < 18 yrs old) dyads were analyzed. In a Generalized Estimation Equation (GEE) logit model for mothers (n = 179) and children (n = 387), maternal untreated caries was a statistically significant correlate of child’s untreated caries, odds ratio (OR) = 1.76 (95%CI: 1.10, 2.70), adjusted for demographic factors. This relationship did not change when behavioral and dental utilization factors were added to the model, OR = 1.85 (95% CI: 1.12, 3.07). Maternal untreated caries almost doubled the odds of children’s untreated caries and significantly increased child’s caries severity by about 3 surfaces. Caries prevention and dental utilization programs for mothers and their children should be increased. PMID:20505046

Beyond mean-field calculations for odd-mass nuclei.  

PubMed

Beyond mean-field methods are very successful tools for the description of large-amplitude collective motion for even-even atomic nuclei. The state-of-the-art framework of these methods consists in a generator coordinate method based on angular-momentum and particle-number projected triaxially deformed Hartree-Fock-Bogoliubov (HFB) states. The extension of this scheme to odd-mass nuclei is a long-standing challenge. We present for the first time such an extension, where the generator coordinate space is built from self-consistently blocked one-quasiparticle HFB states. One of the key points for this success is that the same Skyrme interaction is used for the mean-field and the pairing channels, thus avoiding problems related to the violation of the Pauli principle. An application to ^{25}Mg illustrates the power of our method, as agreement with experiment is obtained for the spectrum, electromagnetic moments, and transition strengths, for both positive and negative parity states and without the necessity for effective charges or effective moments. Although the effective interaction still requires improvement, our study opens the way to systematically describe odd-A nuclei throughout the nuclear chart. PMID:25361253

Fitting stratified proportional odds models by amalgamating conditional likelihoods  

PubMed Central

SUMMARY Classical methods for fitting a varying intercept logistic regression model to stratified data are based on the conditional likelihood principle to eliminate the stratum-specific nuisance parameters. When the outcome variable has multiple ordered categories, a natural choice for the outcome model is a stratified proportional odds or cumulative logit model. However, classical conditioning techniques do not apply to the general K-category cumulative logit model (K > 2) with varying stratum-specific intercepts as there is no reduction due to suffciency; the nuisance parameters remain in the conditional likelihood. We propose a methodology to fit stratified proportional odds model by amalgamating conditional likelihoods obtained from all possible binary collapsing of the ordinal scale. The method allows for categorical and continuous covariates in a general regression framework. We provide a robust sandwich estimate of the variance of the proposed estimator. For binary exposures, we show equivalence of our approach to the estimators already proposed in the literature. The proposed recipe can be implemented very easily in standard software. We illustrate the methods via three real data examples related to biomedical research. Simulation results comparing the proposed method with a random effects model on the stratification parameters are also furnished. PMID:18618428

Inverse Odds Ratio-Weighted Estimation for Causal Mediation Analysis  

PubMed Central

An important scientific goal of studies in the health and social sciences is increasingly to determine to what extent the total effect of a point exposure is mediated by an intermediate variable on the causal pathway between the exposure and the outcome. A causal framework has recently been proposed for mediation analysis, which gives rise to new definitions, formal identification results and novel estimators of direct and indirect effects. In the present paper, the author describes a new inverse odds ratio-weighted (IORW) approach to estimate so-called natural direct and indirect effects. The approach which uses as a weight, the inverse of an estimate of the odds ratio function relating the exposure and the mediator is universal in that it can be used to decompose total effects in a number of regression models commonly used in practice. Specifically, the approach may be used for effect decomposition in generalized linear models with a nonlinear link function, and in a number of other commonly used models such as the Cox proportional hazards regression for a survival outcome. The approach is simple and can be implemented in standard software provided a weight can be specified for each observation. An additional advantage of the method is that it easily incorporates multiple mediators of a categorical, discrete or continuous nature. PMID:23744517

ODD irritability is associated with obsessive-compulsive behavior and not ADHD in chronic tic disorders.  

PubMed

Gilles de la Tourette syndrome (TS) and chronic tic disorder (CT) are often associated with a variety of behavioral comorbidities including attention-deficit hyperactivity disorder (ADHD), obsessive-compulsive behavior (OCB), oppositional-defiant disorder (ODD) and temper outbursts. ODD is often associated with ADHD but its links to other symptoms of TS/CT is not as clear. This study examined whether the various symptoms of ODD were differentially linked to the various comorbidities in TS. A clinical sample of 135 children diagnosed with TS was evaluated through parent questionnaires and semi-structured interviews. Regressions and structural equation modeling confirmed that ODD is multidimensional in a TS/CT sample and showed that OCB was associated with the irritability symptoms of ODD whereas ADHD was associated with the Headstrong symptoms of ODD. Results suggest that increased attention to the different facets of ODD may help improve our understanding of emotional symptoms in TS/CT. PMID:25108592

The Interplay Among Preschool Child and Family Factors and the Development of ODD Symptoms  

PubMed Central

Objective The present study examined (a) the interactions between early behavior, early parenting, and early family adversity in predicting later ODD symptoms, and (b) the reciprocal relations between parent functioning and ODD symptoms across the preschool years. Method Participants were 258 3-year-old children (138 boys and 120 girls) and their parents from diverse backgrounds who participated in a 4-year longitudinal study. Results Early child behavior, parenting, and family adversity did not significantly interact in the predicted direction. Reciprocal relations between ODD symptoms and parent functioning were observed for maternal and paternal depression, and maternal warmth. Paternal laxness at age 4 predicted ODD symptoms at age 5 and paternal laxness at age 5 predicted ODD symptoms at age 6, but child ODD did not significantly predict paternal laxness. Conclusion Results suggest that ODD symptoms may develop through a transactional process between parent and child functioning across the preschool years. PMID:22530755

The Euler current and relativistic parity odd transport  

E-print Network

For a spacetime of odd dimensions endowed with a unit vector field, we introduce a new topological current that is identically conserved and whose charge is equal to the Euler character of the even dimensional spacelike foliations. The existence of this current allows us to introduce new Chern-Simons-type terms in the effective field theories describing relativistic quantum Hall states and (2+1) dimensional superfluids. Using effective field theory, we calculate various correlation functions and identify transport coefficients. In the quantum Hall case, this current provides the natural relativistic generalization of the Wen-Zee term, required to characterize the shift and Hall viscosity in quantum Hall systems. For the superfluid case this term is required to have nonzero Hall viscosity and to describe superfluids with non s-wave pairing.

Effect of odd hydrogen on ozone depletion by chlorine reactions  

NASA Technical Reports Server (NTRS)

The present paper discusses how the shape of the ozone layer changes under the influence of injected ClX for several choices of two key HOx reaction rates. The two HOx reactions are: OH + HO2 yields H2O + O2 and O + HO2 yields OH + O2. Results of calculations are presented which show that the two reaction rates determine the stratospheric concentrations of OH and HO2, and that these concentrations regulate the amount by which the stratospheric ozone column can be reduced due to injections of odd chlorine. It is concluded that the amount of ozone reduction by a given mixing ratio of ClX will remain very uncertain until the significance of several possible feedback effects involving HOx in a chlorine-polluted atmosphere are determined and measurements of the reaction rates and HOx concentrations are made at the relevant temperatures.

An Overview of Modeling Middle Atmospheric Odd Nitrogen  

NASA Technical Reports Server (NTRS)

Odd nitrogen (N, NO, NO2, NO3, N2O5, HNO3, HO2NO2, ClONO2, and BrONO2) constituents are important components in the control of middle atmospheric ozone. Several processes lead to the production of odd nitrogen (NO(sub y)) in the middle atmosphere (stratosphere and mesosphere) including the oxidation of nitrous oxide (N2O), lightning, downflux from the thermosphere, and energetic charged particles (e.g., galactic cosmic rays, solar proton events, and energetic electron precipitation). The dominant production mechanism of NO(sub y) in the stratosphere is N2O oxidation, although other processes contribute. Mesospheric NO(sub y) is influenced by N2O oxidation, downflux from the thermosphere, and energetic charged particles. NO(sub y) is destroyed in the middle atmosphere primarily via two processes: 1) dissociation of NO to form N and O followed by N + NO yielding N2 + O to reform even nitrogen; and 2) transport to the troposphere where HNO3 can be rapidly scavenged in water droplets and rained out of the atmosphere. There are fairly significant differences among global models that predict NO(sub y). NO(sub y) has a fairly long lifetime in the stratosphere (months to years), thus disparate transport in the models probably contributes to many of these differences. Satellite and aircraft measurement provide modeling tests of the various components of NO(sub y). Although some recent reaction rate measurements have led to improvements in model/measurement agreement, significant differences do remain. This presentation will provide an overview of several proposed sources and sinks of NO(sub y) and their regions of importance. Multi-dimensional modeling results for NO(sub y) and its components with comparisons to observations will also be presented.

Proceedings of RIKEN BNL Research Center Workshop: P- and CP-odd Effects in Hot and Dense Matter  

SciTech Connect

This volume contains the proceedings of the RBRC/CATHIE workshop on 'P- and CP-odd Effects in Hot and Dense Matter' held at the RIKEN-BNL Research Center on April 26-30, 2010. The workshop was triggered by the experimental observation of charge correlations in heavy ion collisions at RHIC, which were predicted to occur due to local parity violation (P- and CP-odd fluctuations) in hot and dense QCD matter. This experimental result excited a significant interest in the broad physics community, inspired a few alternative interpretations, and emphasized the need for a deeper understanding of the role of topology in QCD vacuum and in hot and dense quark-gluon matter. Topological effects in QCD are also closely related to a number of intriguing problems in condensed matter physics, cosmology and astrophysics. We therefore felt that a broad cross-disciplinary discussion of topological P- and CP-odd effects in various kinds of matter was urgently needed. Such a discussion became the subject of the workshop. Specific topics discussed at the workshop include the following: (1) The current experimental results on charge asymmetries at RHIC and the physical interpretations of the data; (2) Quantitative characterization of topological effects in QCD matter including both analytical (perturbative and non-perturbative using gauge/gravity duality) and numerical (lattice-QCD) calculations; (3) Topological effects in cosmology of the Early Universe (including baryogenesis and dark energy); (4) Topological effects in condensed matter physics (including graphene and superfiuids); and (5) Directions for the future experimental studies of P- and CP-odd effects at RHIC and elsewhere. We feel that the talks and intense discussions during the workshop were extremely useful, and resulted in new ideas in both theory and experiment. We hope that the workshop has contributed to the progress in understanding the role of topology in QCD and related fields. We thank all the speakers and participants, and express our gratitude to the event coordinator Pam Esposito for her hard work.

T invariance and T-odd asymmetries for the cold-polarized-neutron-induced fission of nonoriented nuclei  

NASA Astrophysics Data System (ADS)

It is shown that the coefficients D exp for all T-odd asymmetries observed experimentally in the cross sections for the reactions of cold-polarized-neutron-induced fission of nonoriented target nuclei (which involves the emission of prescission and evaporated particles) comply in shape and scale with the coefficients D theor calculated for the analogous asymmetries on the basis of quantum-mechanical nuclear-fission theory for T-invariant Hamiltonians of fissile systems. It is also shown that the asymmetries in question arise upon taking into account the effect of (i) the interference between the fission amplitudes of s- and p-wave resonances of a polarized fissile compound nucleus formed in the aforementioned reactions; (ii) the collective rotation of the compound nucleus in question (this rotation entails a change in the angular distributions of fission fragments and third particles); and (iii) the wriggling vibrations of this compound nucleus in the vicinity of its scission point, which lead to the appearance of high aligned spins of fission fragments, with the result that the emission of neutrons and photons evaporated from these fragments becomes anisotropic. The possible contribution of T-noninvariant interactions to the formation of the T-odd asymmetries under analysis is estimated by using the results obtained in experimentally testing the detailed-balance principle, ( P-A) theorem, and T invariance of cross sections for elastic proton-proton and proton-neutron scattering.

In this paper we derive an almost explicit analytic formula for asymptotic eigenenergy expansion of arbitrary odd degree polynomial potentials of the form $V(x)=(ix)^{2N+1}+\\beta _{1}x^{2N}+\\beta _{2}x^{2N-1}+\\cdot \\cdot \\cdot \\cdot \\cdot +\\beta _{2N}x$ where $\\beta _{k}^{\\prime }$s are real or complex for $1\\leq k\\leq 2N$. The formula can be used to find semiclassical analytic expressions for eigenenergies up to any order very efficiently. Each term of the expansion is given explicitly as a multinomial of the parameters $\\beta _{1},\\beta _{2}....$ and $\\beta _{2N}$ of the potential. Unlike in the even degree polynomial case, the highest order term in the potential is pure imaginary and hence the system is non-Hermitian. Therefore all the integrations have been carried out along a contour enclosing two complex turning points which lies within a wedge in the complex plane. With the help of some examples we demonstrate the accuracy of the method for both real and complex eigenspectra.

Redistribution of reactive odd nitrogen in the lower arctic stratosphere  

NASA Technical Reports Server (NTRS)

In-situ measurements of total reactive odd nitrogen NO(y), were made from the NASA DC-8 aircraft in the lower arctic stratosphere during the 1989 Airborne Arctic Stratospheric Expedition. Throughout January and February, NO(y) mixing ratios were typically between 0.5 and 3 parts per billion by volume (ppbv) at altitudes between 10 and 12.5 km. During several flights late in the mission, events of unusually light NO(y) occurred with mixing ratios up to 12 ppbv at these altitudes. Simultaneous measurements of N2O, O3, and H2O during these events suggest that large changes in NO(y) are not expected. The elevated NO(y) values are interpreted as a vertical redistribution of NO(y) in the lower stratosphere resulting from gravitational sedimentation of aerosol particles containing HNO3. No evidence of the redistribution of H2O is noted, consistent with observations of denitrification without dehydration higher in the stratosphere.

Understanding the Odd Shape of Cancer Cell Nuclei | Physical Sciences in Oncology  

Cancer.gov

Misshapen cell nuclei are frequently observed in cancer cells and other diseases, but what causes the abnormality - and why it is associated with certain disorders - has remained unclear. Now, however, researchers at Northwestern University have developed a mathematical model that sheds light on the defect by clarifying the mechanisms that cause bulges known as “blebs” in cells’ nuclear membranes. The research could be a step toward bleb prevention and may ultimately provide potential therapies for cancer and other diseases.

Disaster Impacts on Human Capital Accumulation Shown in the Typhoon Haiyan Case  

NASA Astrophysics Data System (ADS)

School children and their school environment are increasingly exposed to all kinds of hazards. Many disaster events have shown the extent of disaster impacts on the education sector which this study also highlights in the Typhoon Haiyan Case. Disasters do not only cause loss of lives or damage to educational facilities, they also entail significant economic and social consequences on human capital development in the short and long-run. While the trend of short term disaster impact can easily be analyzed in rapid post disaster assessments taking destroyed assets as proxy, usually analyses of medium and long-term effects of disasters include large inherent uncertainties and are of less tangible nature, require more time and complex methods and can often not give comprehensive results. The consequences of disasters especially in developing countries are therefore to a certain extent often left unknown. Generally, economic and social effects of disasters on human capital seem to be ambiguous and to some degree these effects are related to economic, social and institutional well-being. Thus, clear understanding is crucial to interpret its complex effects on human capital accumulation. This essential nature of medium and long-term effects has not been reflected in many analyses. Focus has mostly been given on the extent of physical damage, displacements, lives and assets lost instead of targeting resilience of social and economic characteristics of communities in terms of preventing human capital accumulation disruption. Main objective of this study is to provide a conceptual framework illustrating the impacts of disasters on schooling which might help in assessing such effects, as one of the fundamental components of human capital accumulation (Ozceylan Aubrecht, 2013). The dimensions of human capital building and its relationship to disasters under the light of past disaster events are discussed with a special focus on the recent Typhoon Haiyan that struck the Philippines in November 2013. Natural disasters adversely affect human capital accumulation in several ways including loss of life, damage to the educational system, decreased educational quality, increased child labor, and associated high dropout rates. Another dimension closely related to the human capital is the reduced economic strength of families that can limit the expenditures on well-being, including education, health and food (child malnutrition) (Baez et al., 2010; Cuaresma, 2010). According to information provided by UN and international media approximately 6 million children were affected by Typhoon Haiyan with 1.4 million homes of children and their families destroyed and 1.8 million children displaced. About 90% of the school buildings in the affected region were damaged and schools therefore stayed closed for up to 2 months causing disruption for more than a million pupils and 34,000 teachers. In some areas, when school returned to operation, only half of the school kids reported back. Also for the other pupils the situation was still challenging with many of the prior basic educational resources affected (destroyed textbooks and learning material, damaged classrooms) and no own equipment available (books, pens, etc.). Those reported impacts have already interrupted the educational continuity and it is expected to further continue by adversely affecting human capital accumulation in the longer term. Part of this work has been done under the Global Program for Safer Schools (GPSS) carried out at the Global Facility for Disaster Reduction and Recovery (GFDRR).

Alternative approach to the regularization of odd-dimensional AdS gravity  

NASA Astrophysics Data System (ADS)

In this paper I present an action principle for odd-dimensional AdS gravity which consists of introducing another manifold with the same boundary and a very specific boundary term. This new action allows and alternative approach to the regularization of the theory, yielding a finite Euclidean action and finite conserved charges. The choice of the boundary term is justified on the grounds that an enhanced 'almost off-shell' local AdS/Conformal symmetry arises for that very special choice. One may say that the boundary term is dictated by a guiding symmetry principle. Two sets of boundary conditions are considered, which yield regularization procedures analogous to (but different from) the standard 'background subtraction' and 'counterterms' regularization methods. The Noether charges are constructed in general. As an application it is shown that for Schwarzschild-AdS black holes the charge associated to the time-like Killing vector is finite and is indeed the mass. The Euclidean action for Schwarzschild-AdS black holes is computed, and it turns out to be finite, and to yield the right thermodynamics. The previous sentence may be interpreted in the sense that the boundary term dictated by the symmetry principle is the one that correctly regularizes the action.

Secondary organic aerosol model intercomparison based on secondary organic aerosol to odd oxygen ratio in Tokyo

of secondary organic aerosol (SOA) models is critical for accurate understanding of the behavior and sources of atmospheric aerosols. Over the last decade, a number of SOA production pathways were discovered, and several new SOA models have been developed. However, few comparative studies of the performances of the various SOA models have been conducted. In this study, simulation data obtained with five SOA models (two yield models, a volatility basis set (VBS) model, a mechanistic model, and a near-explicit model) were compared. The performances of the models were evaluated by comparison of the simulated data with observed ratios of the SOA concentration to odd oxygen concentration ([SOA]/[Ox], where [Ox] = [O3] + [NO2]) in the Tokyo metropolitan area. In Tokyo, SOA concentrations have been shown to correlate well with Ox concentrations; thus, Tokyo is an appropriate location for this intercomparison study. All five models showed similar results for the concentrations of gaseous species, including ozone, reactive nitrogen, hydroxy radicals, and volatile organic compounds. In contrast, the simulated SOA concentrations varied substantially among the five models. The VBS model reproduced the observed [SOA]/[Ox] ratio well, whereas the other four models substantially underestimated the ratio. The sensitivity of the ratio to various input parameters differed substantially among the models, as did the volatility distribution of SOA and the source contributions of SOA, suggesting that the choice of SOA model is critical for accurate assessment of the atmospheric behavior and sources of SOA.

Low-lying excited states of the odd-proton nuclei with Z ?100  

NASA Astrophysics Data System (ADS)

Background: Theoretical investigations of the structure of the low-lying states of nuclei with Z ?100 play an important role in understanding the properties of nuclei belonging to the new region of the nuclide chart which is available now for experimental study. Purpose: We perform the calculations of the excitation energies and wave functions of the low-lying states of nuclei with Z ?100. Methods: The quasiparticle-phonon model, which takes into account an interaction of the quasiparticles and phonons of different multipolarities, is used as a basis for the calculations. Results: The excitation energies and the quasiparticle-phonon structure of the low-lying states with excitation energies up to 1200 keV of the odd-proton nuclei 239-251Bk, 243-255Es, 247-257Md, 253,255Lr, and 261,263Db are calculated. Conclusions: It is shown that starting from 600 keV the excitation of the phonons and the quasiparticle-phonon interaction play an important role in the description of the properties of the excited states of nuclei with Z ?100.

Properties of rotating Einstein-Maxwell-dilaton black holes in odd dimensions  

NASA Astrophysics Data System (ADS)

We investigate rotating Einstein-Maxwell-dilaton (EMd) black holes in odd dimensions. Focusing on black holes with equal-magnitude angular momenta, we determine the domain of existence of these black holes. Nonextremal black holes reside with the boundaries determined by the static and the extremal rotating black holes. The extremal EMd black holes show proportionality of their horizon area and their angular momenta. Thus the charge does not enter. We also address the Einstein-Maxwell case, where the extremal rotating black holes exhibit two branches. On the branch emerging from the Myers-Perry solutions, their angular momenta are proportional to their horizon area, whereas on the branch emerging from the static solutions their angular momenta are proportional to their horizon angular momenta. Only subsets of the near-horizon solutions are realized globally. Investigating the physical properties of these EMd black holes, we note that one can learn much about the extremal rotating solutions from the much simpler static solutions. The angular momenta of the extremal black holes are proportional to the area of the static ones for the Kaluza-Klein value of the dilaton coupling constant, and remain analogous for other values. The same is found for the horizon angular velocities of the extremal black holes, which possess an analogous behavior to the surface gravity of the static black holes. The gyromagnetic ratio is rather well approximated by the "static" value, obtained perturbatively for small angular momenta.

A model study of the effects of intermittent loss on odd nitrogen concentrations in the lower troposphere  

NASA Technical Reports Server (NTRS)

A time-dependent box model of the lower troposphere which includes a description of photochemical and physical processes has been developed. This model has been applied to the calculation of nitric acid and NO(x)(NO + NO2) concentrations over a diurnal cycle which includes precipitation. Nitric acid concentrations and the HNO3/NO(x) ratio are found to be highly variable under the assumptions regarding the frequency, duration, and intensity of precipitation employed in this model. The chemistry of odd nitrogen compounds during the night is potentially important in establishing the level of nitric acid in the lower troposphere. These calculations also indicate that relatively large errors may occur when the continuity equation describing nitric acid variations is averaged over a diurnal cycle which includes precipitation. Interpretation of simultaneous measurements of HNO3 and NO(x) will require some knowledge of the history of the observed air mass and may require an improved understanding of nighttime odd nitrogen chemistry.

Increases in weight and body size increase the odds for hypertension during 7 years of follow-up.  

PubMed

Changes in BMI and body size were compared to incident hypertension in 24,550 men and 10,111 women followed prospectively as part of the National Runners' Health Study to test whether long-term weight change affects hypertension risk. Incident hypertensions were reported by 2,143 men and 430 women during (mean +/- s.d.) 7.8 +/- 1.8 and 7.5 +/- 2.0 years of follow-up, respectively. Despite being active, men's and women's BMI increased 1.15 +/- 1.70 and 0.95 +/- 1.89 kg/m(2), respectively, and their waist circumferences increased 2.97 +/- 5.02 and 3.29 +/- 6.67 cm, respectively. Compared to those whose BMI declined, those who gained >or=2.4 kg/m(2) had an odds ratio (95% confidence interval) of 1.68 (1.45, 1.94) for becoming hypertensive if male and 1.42 (1.05, 1.92) if female. Men whose waist circumference increased >or=6 cm had an odds ratio of 1.22 (1.01, 1.47) for becoming hypertensive compared to those whose waists decreased. In both sexes, the odds for hypertension were significantly related to BMI at follow-up when adjusted for baseline BMI, but generally not to baseline BMI when adjusted for follow-up BMI. In the subset whose weights remained relatively unchanged during follow-up (+/-0.4 kg/m(2)), each kg/m(2) increment in BMI was associated with an odds ratio for becoming hypertensive of 1.19 (1.14, 1.24) in men and 1.11 (1.02, 1.20) in women. Thus, even among lean, physically active individuals: (i) weight gain increases hypertension risk; (ii) higher body weight increases the hypertension risk in a dose-dependent manner in the absence of any weight change; and (iii) there is no advantage carried forward to having been previously lean.

Electron-capture branching ratio measurements of odd-odd intermediate nuclei in double-beta decay at the TITAN facility  

NASA Astrophysics Data System (ADS)

A novel technique to measure electron-capture branching ratios is being introduced, where the TITAN ion traps and the ISAC radioactive beam facility at TRIUMF are the central components. The technique will be applied to the intermediate odd-odd nuclei in double-beta decay. The decay properties of these nuclei will constrain theoretical models dealing with the evaluation of the nuclear matrix elements for both the 2 ? and the 0 ? mode. The present setup and its potential for measuring extremely low branching ratios at low instrumental backgrounds is described.

Evaluation of a catalytic reduction technique for the measurement of total reactive odd-nitrogen NOy in the atmosphere  

NASA Technical Reports Server (NTRS)

The suitability of a technique for the measurement of total reactive odd-nitrogen NOy-containing species in the atmosphere has been examined. In the technique, an NOy component species, which may include NO, NO2, NO3, HNO3, peroxyacetyl nitrate, and particulate nitrate, are catalytically reduced by CO to form NO molecules on the surface of a metal converter tube, and the NO product is detected by chemiluminescence produced in reaction with O3. Among the catalysts tested in the temperature range of 25-500 C, Au was the preferred catalyst. The results of laboratory tests investigating the effects of pressure, O3, and H2O on NOy conversion, and the possible sources of interference, have shown that the technique is suitable for atmospheric analyses. The results of a test in ambient air at a remote ground-based field site are included.

We investigate the nonclassical properties of the MCSO-OSCS through Mandel's Q-parameter, quadrature squeezing, the photocount distribution and Wigner function (WF), which is turned out to be influenced by parameters m, ? and ? 0. Especially the volume of negative region of WF could increase through controlling the parameters m, ? and ? 0. We also investigate the decoherence of the MCSO-OSCS in terms of the fadeaway of the negativity of WF in a thermal environment.

We introduce a new non-Gaussian state, generated by m times coherent superposition operation $a\\cos \\theta +a^{\\dagger }e^{i\\varphi }\\sin \\theta $ (MCSO) on odd-Schrodinger-cat state (OSCS). Its normalized constant is turned out to be related with the Hermite polynomial. We further investigate the nonclassical properties of the MCSO-OSCS through Mandel's Q-parameter, quadrature squeezing, the photocount distribution and Wigner function (WF). It is shown that the nonclassicality of the MCSO-OSCS is influenced by the number of times (m) of coherent superpositon operation, the angle $\\theta $ and the amplitude of the coherent state (|$\\alpha _{0}$|). Especially the volume of negative region of WF increases with the increment of parameters m, $\\theta $ and $\\alpha _{0}$. We also investigate the decoherence of the MCSO-OSCS in terms of the fadeaway of the negativity of WF in a thermal environment.

Analytical description of odd-A nuclei near the critical point of the spherical to axially deformed shape transition  

SciTech Connect

A coupling scheme for even-even nuclei with the X(5) critical point symmetry coupled to a single valence nucleon in a j orbit is proposed to approximately describe the critical point phenomena of spherical to axially deformed shape (phase) transition in odd-A nuclear systems. The corresponding scheme, which can be solved analytically, is called the X(5/(2j+1)) model. A special case with j=1/2 is analyzed in detail to show its level structure and transition patterns. It is further shown that {sup 189}Au and {sup 155}Tb may be possible X(5/(2j+1)) symmetry candidates with j=1/2 and j=3/2, respectively.

Testing Lorentz invariance using an odd-parity asymmetric optical resonator  

SciTech Connect

We present the first experimental test of Lorentz invariance using the frequency difference between counter-propagating modes in an asymmetric odd-parity optical resonator. This type of test is {approx}10{sup 4} more sensitive to odd-parity and isotropic (scalar) violations of Lorentz invariance than equivalent conventional even-parity experiments due to the asymmetry of the optical resonator. The disadvantages of odd-parity resonators have been negated by the use of counter-propagating modes, delivering a high level of immunity to environmental fluctuations. With a nonrotating experiment our result limits the isotropic Lorentz violating parameter {kappa}-tilde{sub tr} to 3.4{+-}6.2x10{sup -9}, the best reported constraint from direct measurements. Using this technique the bounds on odd-parity and scalar violations of Lorentz invariance can be improved by many orders of magnitude.

Phenomenology of a littlest Higgs model with T parity: Including effects of T-odd fermions  

NASA Astrophysics Data System (ADS)

We study the collider phenomenology of a littlest Higgs model with T parity. We first stress the important role of the T-odd SU(2)-doublet fermions (introduced to make the model T-parity invariant) in high energy scattering processes, such as qq¯?WH+WH- where WH± are the T-odd partners of W bosons. Because the mass of the T-odd SU(2)-doublet fermions cannot be too heavy to be consistent with low energy data, they can be copiously produced at the CERN Large Hadron Collider (LHC). Therefore, we study the collider phenomenology of the model with emphasis on the contributions of the T-odd fermion to the production of the heavy T-parity partners (either bosons or fermions) of the usual particles at the LHC. The production cross sections and the decay branching ratios of the new heavy particles are classified and various experimental signatures are discussed.

Fission Cross-Section Measurements of the Odd-Odd Isotopes 232Pa, 238Np, and 236Np  

SciTech Connect

Transmutation of actinide waste into fission products could be enhanced by using resonance fission of odd-odd target materials; those of interest are 232Pa, 238Np, and 242Am. Fission cross-section measurements of two of these short-lived materials were performed at Los Alamos National Laboratory. Samples were produced by the (d,2n) reaction in the Los Alamos Ion Beam Facility followed by fast radiochemistry to separate the odd-odd target of interest. The fission cross section of the nanogram samples was measured in a high intensity pulsed neutron beam produced by 800-MeV proton spallation. Using this procedure, the fission cross sections of the 1.3-day 232Pa and 2.1-day 238Np were successfully measured in the energy range from 0.01 eV to 50 keV. The fission cross section of the relatively long-life isotope 236Np was also measured in the same system while the short half-life isotopes were being prepared. The results and resonance analysis are presented.

Finding the Odd One Out in Large Spectroscopic Surveys  

NASA Astrophysics Data System (ADS)

Through shear volume of data, next generation surveys will provide us with unprecedented and detailed information about the full distribution of astronomical sources. Anomalous events influenced by the the most extreme and interesting physics will no longer be relegated to the dustbin of "small number statistics." Unfortunately, that same volume of data will render the task of culling these extreme events from the background of ordinary stars and galaxies virtually impossible. Both the number of events and the dimensionality of the data (e.g. a spectral energy distribution measured in 4000 wavelength bins) exist well outside the reasonable limits of human processing In this context, we seek algorithms to project N>>1 dimensional data down to 2 or 3 effective dimensions, preserving the physics of the correlations within the unprojected data. Inspection in these effective dimensions then allows us to identify both objects that resemble one another (classification of objects) and objects that resemble nothing at all (anomaly detection). We consider both Principal Component Analysis, which attempts the projection under the assumption that any given data point can be reconstructed from a linear combination of all other data points, and Local Linear Embedding, which attempts to reconstruct data points only from their nearest neighbors, preserving the non-linear relationships between different neighborhoods. We use stellar spectra from the SDSS to show how these techniques can identify interesting classes of astronomical sources.

Mother-teacher agreement on preschoolers' symptoms of ODD and CD: does context matter?  

PubMed

The aims of this study were to examine mother-teacher agreement on oppositional defiant disorder (ODD) and conduct disorder (CD) symptoms and diagnoses in preschool children; to determine if context is a source of disagreement; and to explore if sex, referral status, and age moderated agreement rates. Participants included 158 male and 139 female 3- to 5-year old preschool children, their mothers, and teachers. A structured interview, the Kiddie-Disruptive Behavior Disorder Schedule was used for maternal report and teachers completed the Early Childhood Inventory. Results indicated that mothers reported more symptoms and diagnoses of ODD and CD than teachers, and mother-teacher agreement on both ODD and CD symptoms and diagnoses was low. Level of mother-teacher agreement increased when reporting on behavior in the same context; however, the rates remain modest. Referral status increased the likelihood of mother and teacher agreement on several ODD and CD symptoms, as well as ODD and CD diagnosis. These data suggest that context plays a role in mother-teacher agreement in the assessment of young children's ODD and CD symptoms. PMID:22661105

Efficient odd straight medium chain free fatty acid production by metabolically engineered Escherichia coli.  

PubMed

Free fatty acids (FFAs) can be used as precursors for the production of biofuels or chemicals. Different composition of FFAs will be useful for further modification of the biofuel/biochemical quality. Microbial biosynthesis of even chain FFAs can be achieved by introducing an acyl-acyl carrier protein thioesterase gene into E. coli. In this study, odd straight medium chain FFAs production was investigated by using metabolic engineered E. coli carrying acyl-ACP thioesterase (TE, Ricinus communis), propionyl-CoA synthase (Salmonella enterica), and ?-ketoacyl-acyl carrier protein synthase III (four different sources) with supplement of extracellular propionate. By using these metabolically engineered E. coli, significant quantity of C13 and C15 odd straight-chain FFAs could be produced from glucose and propionate. The highest concentration of total odd straight chain FFAs attained was 1205?mg/L by the strain HWK201 (pXZ18, pBHE2), and 85% of the odd straight chain FFAs was C15. However, the highest percentage of odd straight chain FFAs was achieved by the strain HWK201 (pXZ18, pBHE3) of 83.2% at 48?h. This strategy was also applied successfully in strains carrying different TE, such as the medium length acyl-ACP thioesterase gene from Umbellularia californica. C11 and C13 became the major odd straight-chain FFAs. PMID:24889416

The development of hurricane Inez, 1966, as shown by satellite nighttime radiometric and daytime television coverage  

NASA Technical Reports Server (NTRS)

A complete documentation of Numbus 2 High Resolution infrared Radiometer data and ESSA-1 and 3 television photographs is presented for the life-time of Hurricane Inez, 1966. Ten computer produced radiation charts were analyzed in order to delineate the three dimensional cloud structure during the formative, mature and dissipating stages of this tropical cyclone. Time sections were drawn throughout the storm's life cycle to relate the warm core development and upper level outflow of the storm with their respective cloud canopies, as shown by the radiation data. Aerial reconnaissance weather reports, radar photographs and conventional weather analyses were used to complement the satellite data. A computer program was utilized to accept Nimbus 2 HRIR equivalent blackbody temperatures within historical maximum and minimum sea surface temperature limits over the tropical Atlantic Ocean.

The Double Red Giant Binary With Odd Oscillations  

NASA Astrophysics Data System (ADS)

Red giants in eclipsing binaries are excellent tools for studying the interplay among stellar evolution, binarity, and solar-like oscillations. We present a detailed look at one unique system composed of two red giants, KIC 9246715. One of the stars exhibits solar-like oscillations that are weaker than expected, and the other shows none at all. To address this oddity, we combine four years of Kepler light curves, radial velocity curves for both stars, and stellar atmosphere models for each star's extracted spectrum. Our final, well-constrained photodynamic model yields new physical insights for both stars in the binary, puts asteroseismology to the test, and paves the way for detailed studies of other red giant eclipsing binaries with main-sequence companions. This work summarizes the main results of a new paper by Rawls et al.

Organic solute changes with acidification in Lake Skjervatjern as shown by 1H-NMR spectroscopy  

USGS Publications Warehouse

1H-NMR spectroscopy has been found to be a useful tool to establish possible real differences and trends between all natural organic solute fractions (fulvic acids, humic acids, and XAD-4 acids) after acid-rain additions to the Lake Skjervatjern watershed. The proton NMR technique used in this study determined the spectral distribution of nonexchangeable protons among four peaks (aliphatic protons; aliphatic protons on carbon ?? or attached to electronegative groups; protons on carbons attached to O or N heteroatoms; and aromatic protons). Differences of 10% or more in the respective peak areas were considered to represent a real difference. After one year of acidification, fulvic acids decreased 13% (relative) in Peak 3 protons on carbon attached to N and O heteratoms and exhibited a decrease in aromatic protons between 27% and 31%. Humic acids also exhibited an 11% relative decrease in aromatic protons as a result of acidification. After one year of acidification, real changes were shown in three of the four proton assignments in XAD-4 acids. Peak 1 aliphatic protons increased by 14% (relative), Peak 3 protons on carbons attached to O and N heteroatoms decreased by 13% (relative), and aromatic protons (Peak 4) decreased by 35% (relative). Upon acidification, there was a trend in all solutes for aromatic protons to decrease and aliphatic protons to increase. The natural variation in organic solutes as shown in the Control Side B of the lake from 1990 to 1991 is perhaps a small limitation to the same data interpretations of acid rain changes at the Lake Skjervatjern site, but the proton NMR technique shows great promise as an independent scientific tool to detect and support other chemical techniques in establishing organic solute changes with different treatments (i.e., additions of acid rain).

Even-odd effects in prompt emission of spontaneously fissioning even-even Pu isotopes  

NASA Astrophysics Data System (ADS)

The available experimental Y (A , TKE) data for 236,238,240,242,244Pu(SF) together with the Zp model prescription with appropriate parameters allows the investigation of even-odd effects in fragment distributions. The size of the global even-odd effect in Y (Z) is decreasing from 244Pu(SF) to 236Pu(SF) confirming the general observation of a decrease of the even-odd effect with the fissility parameter. Charge polarizations (?Z) and root-mean squares (rms) as a function of A of 236-244Pu(SF) were obtained for the first time. In the asymmetric fission region both ?Z (A) and rms (A) exhibit oscillations with a periodicity of about 5 mass units due to the even-odd effects. The total average charge deviations < ?Z > (obtained by averaging ?Z (A) over the experimental Y (A) distribution) are of about |0.5| for all studied Pu(SF) systems. The comparison of the calculated ?Z (A) and rms (A) of 240Pu(SF) with those of 239Pu (nth , f) reported by Wahl shows an in-phase oscillation with a higher amplitude in the case of 240Pu(SF), confirming the higher even-odd effect in the case of SF. As in the previously studied cases (233,235U (nth , f), 239Pu (nth , f), 252Cf(SF)) the even-odd effects in the prompt emission of 236-244Pu(SF) are mainly due to the Z even-odd effects in fragment distributions and charge polarizations and the N even-odd effects in the average neutron separation energies from fragments < Sn >. The size of the global N even-odd effect in < Sn > is decreasing with the fissility parameter, being higher for the Pu(SF) systems compared to the previously studied systems. The prompt neutron multiplicities as a function of Z, ? (Z), exhibit sawtooth shapes with a visible staggering for asymmetric fragmentations. The size of the global Z even-odd effect in ? (Z) exhibits a decreasing trend with increasing fissility. The average prompt neutron multiplicities as a function of TKE show an increase of the even-odd effect with increasing TKE, with global effect sizes close to each other (a decrease of the effect for heavier fissioning nuclei is not observed here). The amounts of the global even-odd effect in Y (Z) and of the N even-odd effect in < Sn > of 240Pu(SF) are larger compared to 239Pu (nth , f). This fact affects the prompt emission leading to a lower Z even-odd effect in the prompt neutron multiplicity of 240Pu(SF) compared to 239Pu (nth , f).

Can an oral mechanism examination contribute to the assessment of odds of aspiration?  

PubMed

Use of an oral mechanism examination is ubiquitous and long-standing despite a paucity of research supporting its clinical utility in dysphagia diagnostics. The purpose of this study was to investigate whether components of an oral mechanism examination, i.e., binary judgments (complete/incomplete) of labial closure, lingual range of motion, and facial symmetry, were associated with increased odds of aspiration as confirmed by subsequent instrumental testing. Study design was a single-group consecutively referred case series with a single judge. A total of 4,102 consecutive inpatients from a large, urban, tertiary-care teaching hospital were accrued, with 3,919 meeting the inclusion criterion of adequate cognitive ability to participate in an oral mechanism examination followed immediately by a fiberoptic endoscopic evaluation of swallowing. Stepwise multiple logistic regression analysis indicated that participants with incomplete lingual range of motion had an odds of aspiration that was 2.72 times the odds of aspiration of those with complete lingual range of motion (95% confidence interval [CI] = 1.96-3.79, p < 0.0001), and incomplete lingual range of motion was an independent risk factor for aspiration regardless of labial closure and facial symmetry. Participants with incomplete facial symmetry had an odds of aspiration that was 0.76 times the odds of aspiration of those with complete facial symmetry (95% CI = 0.61-0.95, p = 0.017). Isolated incomplete labial closure did not affect the odds of aspiration (p > 0.05). New and clinically relevant information was found for lingual range of motion and facial symmetry, i.e., when incomplete, the clinician should be alerted to potential increased odds of aspiration during subsequent instrumental dysphagia testing.

Vesicular transport and apotransferrin in intestinal iron absorption, as shown in the Caco-2 cell model.  

PubMed

The potential roles of vesicular transport and apotransferrin (entering from the blood) in intestinal Fe absorption were investigated using Caco-2 cell monolayers with tight junctions in bicameral chambers as a model. As shown previously, addition of 39 microM apotransferrin (apoTf) to the basolateral fluid during absorption studies markedly stimulated overall transport of 1 microM (59)Fe from the apical to the basal chamber and stimulated its basolateral release from prelabeled cells, implicating endo- and exocytosis. Rates of transport more than doubled. Uptake was also stimulated, but only 20%. Specific inhibitors of aspects of vesicular trafficking were applied to determine their potential effects on uptake, retention, and basolateral (overall) transport of (59)Fe. Nocodazole and 5'-(4-fluorosulfonylbenzoyl)-adenosine each reduced uptake and basolateral transport up to 50%. Brefeldin A inhibited about 10%. Tyrphostin A8 (AG10) reduced uptake 35% but markedly stimulated basolateral efflux, particularly that dependent on apoTf. Cooling of cells to 4 degrees C (which causes depolymerization of microtubules and lowers energy availability) profoundly inhibited uptake and basolateral transfer of Fe (7- to 12-fold). Apical efflux (which was substantial) was not temperature affected. Our results support the involvement of apoTf cycling in intestinal Fe absorption and indicate that as much as half of the iron uses apoTf and non-apoTf-dependent vesicular pathways to cross the basolateral membrane and brush border of enterocytes.

Ancient Grandeur of the Vertebrate Neuropeptide Y System Shown by the Coelacanth Latimeria chalumnae  

PubMed Central

The neuropeptide Y (NPY) family receptors and peptides have previously been characterized in several tetrapods, teleost fishes, and in a holocephalan cartilaginous fish. This has shown that the ancestral NPY system in the jawed vertebrates consisted of the peptides NPY and peptide YY (PYY) and seven G-protein-coupled receptors named Y1–Y8 (Y3 does not exist). The different vertebrate lineages have subsequently lost or gained a few receptor genes. For instance, the human genome has lost three of the seven receptors while the zebrafish has lost two and gained two receptor genes. Here we describe the NPY system of a representative of an early diverging lineage among the sarcopterygians, the West Indian Ocean coelacanth Latimeria chalumnae. The coelacanth was found to have retained all seven receptors from the ancestral jawed vertebrate. The receptors display the typical characteristics found in other vertebrates. Interestingly, the coelacanth was found to have the local duplicate of the PYY gene, called pancreatic polypeptide, previously only identified in tetrapods. Thus, this duplication took place very early in the sarcopterygian lineage, before the origin of tetrapods. These findings confirm the ancient complexity of the NPY system and show that mammals have lost more NPY receptors than any other vertebrate lineage. The coelacanth has all three peptides found in tetrapods and has retained the ancestral jawed vertebrate receptor repertoire with neither gains or losses. PMID:23483106

Merkel cell carcinoma: The first human cancer shown to be associated with a polyomavirus.  

PubMed

Merkel cell carcinoma (MCC) is a rare, malignant primary neuroendocrine cancer of the skin, usually affecting elderly, white people in sun-exposed areas. This is a highly aggressive tumor with strong propensity to metastasize. Surgery and radiation therapy remain the mainstay of treatment, with no curative treatment in case of disseminated metastases. Until 2008, MCC was thought to be caused by the malignant transformation of resident Merkel cells, but no investigation of a predominant molecular pathway that could be involved in MCC pathogenesis was successful. A real revolution in MCC understanding and management occurred in 2008, when a new human polyomavirus (MCPyV) was found to be the main etiological agent of this skin cancer. Following the discovery of MCPyV, the association of MCPyV with MCC has been confirmed worldwide, with detection of MCPyV in about 80% of MCCs. At the same time it had been shown that MCPyV infection is almost ubiquitous in healthy subjects, and MCPyV is thought to be persistent resident of the skin microbiome although the route of transmission, the host cell, the viral cycle and/or latency remain unknown. Most studies suggest that there may be two subtypes of MCC: MCPyV-positive (80%) and MCPyV-negative (20%) MCCs, and various studies have reported a better prognosis associated with MCPyV infection. The discovery of MCPyV in MCC patients opens up new therapeutic insights. The necessity and persistence of expression of MCPyV oncoproteins during MCC development make these proteins promising therapeutic targets. PMID:25455636

Complicated feature of atmospheric aerosols shown in the yellow sand events in Japan  

NASA Astrophysics Data System (ADS)

It is well known that aerosol has a significant potential to the earth's climate. The aerosol distributions in Asia are very complex due to the increasing emissions of small anthropogenic particles associated with economic growth and large dust particles called yellow sands transported on the westerly wind from the continental desert areas. In this study, aerosol properties in the yellow sand events are focused and analyzed from comprehensive aspects. Yellow sand events have often happened in spring. Therefore they have been called 'spring haze' involving an expectation of coming spring to Japan. However the recent yellow sand events are too heavy and too severe to call 'spring haze' due to the increasing of desert areas and contamination with the anthropogenic emissions. The sun/sky photometry has been undertaken at NASA/AERONET stations in Osaka, Shirahama and Noto in Japan. Suspended particulate matter (PM) and OBC (Optical Black Carbon) have been simultaneously measured there. The simultaneous monitoring of aerosols and PM provides such a relation between them as there is a linear correlation between PM concentrations and AOT, which indicates that AOT can be estimated from PM data, and vice versa. It is found that the value of aerosol optical thickness (AOT) during aerosol event is more than double its usual value, and fine anthropogenic particles dominate even during dust events in Japan. It is of interest to mention that yellow sand events in Japan seem to be caused by a mixture of non-absorbing coarse dust and other small haze particles, especially shown in the event in May 2007. A new instrument of NIES/LIDAR network to be set at AERONET/Osaka station in March 2008 is expected to provide us with the vertical distribution of yellow sand particles. Furthermore the model simulations with SPRINTARS/AGCM/CCSR/NIES/FRCGC and satellite data will be available for our better understanding of the beyond pollution of the atmosphere.

Shell-model study of spectroscopies and isospin structures in odd-odd $N=Z$ nuclei employing realistic \\emph{NN} potentials  

E-print Network

The structures of odd-odd $N=Z$ nuclei in the lower \\emph{fp} shell have been investigated with a new isospin-nonconserving microscopical interaction. The interaction is derived from a high-precision charge-dependent Bonn nucleon-nucleon potential using the folded-diagram renormalization method. Excellent agreements with experimental data have been obtained up to band terminations. Particularly, the relative positions of T=0 and T=1 bands were well reproduced. Calculations with another interaction obtained from the Idaho-A chiral potential showed similar results. Our calculations also give a good description of the existence of high-spin isomeric states in the $0f_{7/2}$ sub-shell. As examples, the spectroscopies and isospin structures of $^{46}$V and $^{50}$Mn have been discussed in detail, with the useful predictions of level structures including electromagnetic properties. Results for $^{50}$Mn were analyzed where experimental observations are still insufficient.

Anger and Irritability Symptoms among Youth with ODD: Cross-Informant Versus Source-Exclusive Syndromes  

PubMed Central

We examined differences in co-occurring psychological symptoms and background characteristics among clinically referred youth with oppositional defiant disorder (ODD) with and without anger/irritability symptoms (AIS) according to either parent or teacher (source-exclusive) and both informants (cross-informant), youth with noncompliant symptoms (NS) of ODD, and non-ODD clinic controls. Parents and teachers evaluated 1127 youth (ages 6–18) with a DSM-IV-referenced rating scale to assess ODD and co-occurring psychological symptoms. Parents also completed a background questionnaire (demographic, developmental, treatment, relationship, and academic characteristics) and teachers rated school functioning. Source-exclusive AIS groups were associated with different clinical features, and there was some evidence that cross-informant youth had more mental health concerns than source-exclusive groups. Findings varied to some extent among older (12–18 years) versus younger (6–11 years) youth. In general, the NS group (youth without AIS) was the most similar to clinic controls. AIS and NS are likely candidates for component phenotypes in ODD and continued research into their pathogenesis may have important implications for nosology, etiology, and intervention.

Oppositional defiant disorder (ODD), the forerunner of alcohol dependence: a controlled study.

There are common genetic, neurobiological and psycho-social substrates for oppositional defiant disorder (ODD) and substance dependence. ODD can be regarded as the mildest and earliest form of disruptive behavioral disorder and also represents the threshold of vulnerability for substance dependence. But it is a less researched area. The aim of this research was to study any possible association between childhood ODD and adult alcohol dependence. Data are presented from a non probability sample of 100 adult alcohol dependent subjects and equal number of biologically unrelated control subjects. Assessment was conducted by the instrument Semi-Structured Assessment for the Genetics of Alcoholism for both the assessment of ODD and alcohol dependence. The results of this study demonstrated significant association between childhood ODD and adult alcohol dependence. The association remained significant even after the exclusion of the possible confounding effects of the presence of conduct disorder and attention deficit hyperactivity disorder. Our study should encourage further research in this area and is expected to open up an opportunity for preventive research. PMID:25453690

Reduced visual surround suppression in schizophrenia shown by measuring contrast detection thresholds  

PubMed Central

Visual perception in schizophrenia is attracting a broad interest given the deep knowledge that we have about the visual system in healthy populations. One example is the class of effects known collectively as visual surround suppression. For example, the visibility of a grating located in the visual periphery is impaired by the presence of a surrounding grating of the same spatial frequency and orientation. Previous studies have suggested abnormal visual surround suppression in patients with schizophrenia. Given that schizophrenia patients have cortical alterations including hypofunction of NMDA receptors and reduced concentration of GABA neurotransmitter, which affect lateral inhibitory connections, then they should be relatively better than controls at detecting visual stimuli that are usually suppressed. We tested this hypothesis by measuring contrast detection thresholds using a new stimulus configuration. We tested two groups: 21 schizophrenia patients and 24 healthy subjects. Thresholds were obtained using Bayesian staircases in a four-alternative forced-choice detection task where the target was a grating within a 3? Butterworth window that appeared in one of four possible positions at 5? eccentricity. We compared three conditions, (a) target with no-surround, (b) target embedded within a surrounding grating of 20? diameter and 25% contrast with same spatial frequency and orthogonal orientation, and (c) target embedded within a surrounding grating with parallel (same) orientation. Previous results with healthy populations have shown that contrast thresholds are lower for orthogonal and no-surround (NS) conditions than for parallel surround (PS). The log-ratios between parallel and NS thresholds are used as an index quantifying visual surround suppression. Patients performed poorly compared to controls in the NS and orthogonal-surround conditions. However, they performed as well as controls when the surround was parallel, resulting in significantly lower suppression indices in patients. To examine whether the difference in suppression was driven by the lower NS thresholds for controls, we examined a matched subgroup of controls and patients, selected to have similar thresholds in the NS condition. Patients performed significantly better in the PS condition than controls. This analysis therefore indicates that a PS raised contrast thresholds less in patients than in controls. Our results support the hypothesis that inhibitory connections in early visual cortex are impaired in schizophrenia patients. PMID:25540631

Critical-Point Symmetries in Boson-Fermion Systems: The Case of Shape Transitions in Odd Nuclei in a Multiorbit Model  

SciTech Connect

We investigate phase transitions in boson-fermion systems. We propose an analytically solvable model [E(5/12)] to describe odd nuclei at the critical point in the transition from the spherical to {gamma}-unstable behavior. In the model, a boson core described within the Bohr Hamiltonian interacts with an unpaired particle assumed to be moving in the three single-particle orbitals j=1/2, 3/2, 5/2. Energy spectra and electromagnetic transitions at the critical point compare well with the results obtained within the interacting boson-fermion model, with a boson-fermion Hamiltonian that describes the same physical situation.

Reference surface calibration of a Fizeau interferometer through even/odd synthesis.  

PubMed

We propose an even-/odd-synthesis method for the elimination of additional aberration caused by misalignment or environmental vibration during the calibration of a Fizeau interferometer reference surface (RS). The odd and even parts of an RS can be obtained, because surface errors could be divided into rotationally symmetric and nonrotationally symmetric terms. We then propose a least-squares algorithm with a dual-objective optimization function for calibration of the measurement results at the confocal position. Finally, a complete RS can be eventually obtained by synthesizing the odd and even parts of the RS. It has been verified through experiments that the measurement repeatability of the PV value is better than 0.003?, and the root-mean-square value is better than 0.0003?. PMID:21743557

Correlation of Secondary Organic Aerosol with Odd Oxygen in Mexico City  

SciTech Connect

Data collected from a mountain location within the Mexico City limits are used to demonstrate a correlation between secondary organic aerosol and odd-oxygen (O3 + NO2). Positive matrix factorization techniques are employed to separate organic aerosol components: hydrocarbon-like organic aerosol; oxidized-organic aerosol; and biomass burning organic aerosol. The measured hydrocarbon-like organic aerosol is correlated with urban CO (8±1) µg m-3 ppmv-1. The measured oxidized-organic aerosol is associated with photochemical oxidation products and correlates with odd-oxygen with an apparent slope of (70-120) µg m-3 ppmv-1. The dependence of the oxidized-organic aerosol to odd-oxygen correlation on the nature of the gas-phase hydrocarbon profile is discussed.

Odd-Even Pattern Observed in Polyaniline/(Au0 – Au8) Composites  

SciTech Connect

Theoretically predicted effect of odd-even pattern of electron pairing on behavior of gold clusters in polyaniline/AuN (N = 0 to 8) has been confirmed experimentally. In these composites the atomic Au clusters with even number of atoms exhibit higher catalytic activity for electrochemical oxidation of n-propanol in 1 M NaOH than the odd-number atoms clusters. Also, infrared spectroscopy shows that even numbered PANI/AuN composites affect the N-H stretching vibration more strongly than the corresponding odd numbered ones. This behavior matches the theoretically predicted variations of HOMO-LUMO gap energy and the stability of the atomic Au clusters. It also agrees with the earlier experimental work in which the UPS spectra of isolated, mass-selected Au clusters have been reported.

Odd-Even Effect in Molecular Electronic Transport via an Aromatic Ring.  

PubMed

A distinct odd-even effect on the electrical properties, induced by monolayers of alkyl-phenyl molecules directly bound to Si(111), is reported. Monomers of H2C?CH-(CH2)n-phenyl, with n = 2-5, were adsorbed onto Si-H and formed high-quality monolayers with a binding density of 50-60% Si(111) surface atoms. Molecular dynamics simulations suggest that the binding proximity is close enough to allow efficient ?-? interactions and therefore distinctly different packing and ring orientations for monomers with odd or even numbers of methylenes in their alkyl spacers. The odd-even alternation in molecular tilt was experimentally confirmed by contact angle, ellipsometry, FT-IR, and XPS with a close quantitative match to the simulation results. The orientations of both the ring plane and the long axis of the alkyl spacer are more perpendicular to the substrate plane for molecules with an even number of methylenes than for those with an odd number of methylenes. Interestingly, those with an even number conduct better than the effectively thinner monolayers of the molecules with the odd number of methylenes. We attribute this to a change in the orientation of the electron density on the aromatic rings with respect to the shortest tunneling path, which increases the barrier for electron transport through the odd monolayers. The high sensitivity of molecular charge transport to the orientation of an aromatic moiety might be relevant to better control over the electronic properties of interfaces in organic electronics.

Odd sensation induced by moving-phantom which triggers subconscious motor program.  

PubMed

Our motor actions are sometimes not properly performed despite our having complete understanding of the environmental situation with a suitable action intention. In most cases, insufficient skill for motor control can explain the improper performance. A notable exception is the action of stepping onto a stopped escalator, which causes clumsy movements accompanied by an odd sensation. Previous studies have examined short-term sensorimotor adaptations to treadmills and moving sleds, but the relationship between the odd sensation and behavioral properties in a real stopped-escalator situation has never been examined. Understanding this unique action-perception linkage would help us to assess the brain function connecting automatic motor controls and the conscious awareness of action. Here we directly pose a question: Does the odd sensation emerge because of the unfamiliar motor behavior itself toward the irregular step-height of a stopped escalator or as a consequence of an automatic habitual motor program cued by the escalator itself. We compared the properties of motor behavior toward a stopped escalator (SE) with those toward moving escalator and toward a wooden stairs (WS) that mimicked the stopped escalator, and analyzed the subjective feeling of the odd sensation in the SE and WS conditions. The results show that moving escalator-specific motor actions emerged after participants had stepped onto the stopped escalator despite their full awareness that it was stopped, as if the motor behavior was guided by a "phantom" of a moving escalator. Additionally, statistical analysis reveals that postural forward sway that occurred after the stepping action is directly linked with the odd sensation. The results suggest a dissociation between conscious awareness and subconscious motor control: the former makes us perfectly aware of the current environmental situation, but the latter automatically emerges as a result of highly habituated visual input no matter how unsuitable the motor control is. This dissociation appears to yield an attribution conflict, resulting in the odd sensation. PMID:19492054

Time-odd triaxial relativistic mean field approach for nuclear magnetic moments  

E-print Network

The time-odd triaxial relativistic mean field approach is developed and applied to the investigation of the ground-state properties of light odd-mass nuclei near the double-closed shells. The nuclear magnetic moments including the isoscalar and isovector ones are calculated and good agreement with Schmidt values is obtained. Taking $^{17}$F as an example, the splitting of the single particle levels (around $~0.7$ MeV near the Fermi level), the nuclear current, the core polarizations, and the nuclear magnetic potential, i.e., the spatial part of the vector potential, due to the violation of the time reversal invariance are investigated in detail.

We study the transverse momentum dependent quark-gluon-quark correlation function. Using a spectator diquark model, we calculate the eight time-reversal-odd interaction-dependent twist-3 quark distributions appearing in the decomposition of the transverse momentum dependent quark-gluon-quark correlator. In order to obtain finite results, we assume a dipole form factor for the nucleon-quark-diquark coupling, instead of a point-like coupling. The results are compared with the time-reversal-odd interaction-independent twist-3 TMDs calculated in the same model.

Role of pairing interaction in neutron rich odd and even Zr nuclei  

SciTech Connect

Neutron rich Zr nuclei with number of neutrons between N=50 and 82 are investigated in the relativistic mean field approach in coordinate space. The resonant levels in the positive energy continuum have been explicitly included in the calculation. Odd nuclei have been treated in the blocking approximation. Our calculation indicates that the dripline for odd mass isotopes is far away from that for the even mass ones. Pairing interaction plays a significant role in stabilizing the even isotopes, thus extending the dripline for them.

Collective states of odd nuclei in a model with quadrupole-octupole degrees of freedom  

SciTech Connect

We apply the collective axial quadrupole-octupole Hamiltonian to describe the rotation-vibration motion of odd nuclei with Coriolis coupling between the even-even core and the unpaired nucleon.We consider that the core oscillates coherently with respect to the quadrupole and octupole axialdeformation variables. The coupling between the core and the unpaired nucleon provides a split paritydoublet structure of the spectrum. The formalism successfully reproduces the parity-doublet splitting in a wide range of odd-A nuclei. It provides model estimations for the third angular-momentum projection K on the intrinsic symmetry axis and the related intrinsic nuclear structure.

Quantum Statistical Properties of the Even and Odd Negative Binomial States  

NASA Astrophysics Data System (ADS)

The properties of the even and odd negative binomial states are investigated. Mainly we concentrate on the statistical properties for such states and we consider the squeezing phenomenon by examining the variation in the quadrature variances. Using the Pegg-Barnett formalism of phase operator, the phase probability distributions of the states are discussed, and also the phase and number squeezing with different parameters are studied. The numerical computation results show that the phase probability distributions for the even and odd NBSs can clearly exhibit the different features of quantum effects.

The amplitude of even-odd staggering effects seems to be related to the neutron to proton ratio N/Z of the entrance channels. A qualitative explanation of this effect, taking into account the deexcitation phase of primary excited fragments, is discussed.

From Diphoton GDAs and Photon GPDs to the chiral odd Photon DA  

E-print Network

The photon is a very interesting object for QCD studies since it has both a pointlike coupling to quarks, which yields a perturbative part of photon's wave function, and a non-perturbative coupling related to the magnetic susceptibility of the QCD vacuum and which builds its chiral-odd twist-2 distribution amplitude. The first feature allows us to compute the photon anomalous generalized parton distributions (GPD) and the diphoton generalized distribution amplitudes. The second feature allows us to use a transverse spin asymmetry to probe the chiral odd distribution amplitude of the photon.

Discrimination of the light CP-odd scalars between in the NMSSM and in the SLHM  

E-print Network

The presence of the light CP-odd scalar boson predicted in the next-to-minimal supersymmetric model (NMSSM) and the simplest little Higgs model (SLHM) dramatically changes the phenomenology of the Higgs sector. We suggest a practical strategy to discriminate the underlying model of the CP-odd scalar boson produced in the decay of the standard model-like Higgs boson. We define the decay rate of "the non $b$-tagged jet pair" with which we compute the ratio of decay rates into lepton and jets. They show much different behaviors between the NMSSM and the SLHM.

Microscopic description of the odd-even effect in cold fission  

NASA Astrophysics Data System (ADS)

The time-dependent equations of motion for the pair-breaking effect were corroborated with a condition that fixes dynamically the number of particles on the two-fission fragment. The single-particle level scheme was calculated with the Woods-Saxon superasymmetric two-center shell model. This model provides a continuous variation of the energies from one nucleus up to two separated fragments. The dissipated energy resorts from the time-dependent pairing equations. A peculiar phenomenon was observed experimentally in cold fission: the odd partition yields are favored over the even ones. This odd-even effect for cold fission was explained microscopically.

Barium even-to-odd isotope abundance ratios in thick disk and thin disk stars  

E-print Network

We present the Ba even-to-odd isotope abundance ratios in 25 cool dwarf stars with the metallicity [Fe/H] ranged between 0.25 and --1.35. Our method takes advantage of the hyperfine structure (HFS) affecting the \\ion{Ba}{ii} resonance line of the odd isotopes. The fractional abundance of the odd isotopes of Ba is derived from a requirement that Ba abundances from the resonance line $\\lambda 4554$ and subordinate lines $\\lambda 5853$ and $\\lambda 6496$ must be equal. The results are based on NLTE line formation and analysis of high resolution (R $\\sim60000$) high signal-to-noise (S/N $\\ge 200$) observed spectra. We find that the fraction of the odd isotopes of Ba grows toward the lower Ba abundance (or metallicity) and the mean value in the thick disk stars equals 33 $\\pm$ 4%. This indicates the higher contribution of the $r-$process to barium in the thick disk stars compared to the solar system matter. The obtained fraction increases with the [Eu/Ba] abundance ratio growth in agreement with expectations. A significant fraction of the \\emph{even} isotopes of Ba found in old Galactic stars (the thick disk stars), $\\sim67$%, is in contrast to the prediction of the "classical" model of the $s-$process and favors the value predicted by the "stellar" models of Arlandini et al. (1999) and Travaglio et al. (1999).

The N3 is sensitive to odd-even congruency information in arithmetic fact retrieval.  

PubMed

This study investigated the behavioral and electrophysiological effects elicited by adults' simple addition verification when false answers agree or disagree with the odd-even status of the correct sum (parity congruency vs. parity incongruency), while they are near or far from correct (small vs. large splits). Event-related brain potentials were recorded from 18 students using a first-answer-then-problem paradigm. The results showed that odd-even congruency had a significant effect on the N3 latency with a small, but not a large split. Specifically, odd-even congruent answers with a small split elicited an N3 with a longer latency. Analyses of RT similarly indicated a bigger parity-congruency effect with small-split answers compared with large-split answers. This pattern parallels the corresponding effects on N3 and confirms that the N3 is sensitive to odd-even information in arithmetic fact retrieval and that there are clear links between the event-related brain potential pattern and behavioral effects.

Co-occurrence of ODD and Anxiety: Shared Risk Processes and Evidence for a Dual-Pathway Model  

PubMed Central

Although oppositional defiant disorder (ODD) and anxiety disorders (ADs) often co-occur, the literature is mixed regarding the effects of such co-occurrence. For example, there is evidence that AD symptoms may mitigate ODD symptoms (buffer hypothesis) or exacerbate ODD symptoms (multiple problem hypothesis). A dual-pathway model incorporates previous research and addresses both hypotheses. We describe several possible etiological or risk processes that may underlie each of these ODD–AD pathways, including child temperament, aggression, limbic system processes, executive functioning abilities, and social information–processing biases, and suggest an integrated model. We conclude with implications for the model and directions for future research involving co-occurring ODD and ADs. PMID:21442035

Enhancement of "CP-odd" Higgs Boson Production in the Minimal Supersymmetric Standard Model with Explicit CP Violation  

E-print Network

We calculate the production cross section of the ``CP-odd'' Higgs boson via gluon fusion in the minimal supersymmetric standard model with explicit CP violation in the stop sector. We show that there is a parameter region in which the cross section is enhanced by a factor of about 1000, as compared to the case without CP violation in the stop sector. In the parameter region where the ``CP-odd'' Higgs boson can decay into a stop pair, the stop pair events will be the important signature of the enhanced ``CP-odd'' Higgs boson. In the case where the ``CP-odd'' Higgs boson cannot decay into any superparticles, the gamma gamma and tau tau decay channels could become important for discovering the ``CP-odd'' Higgs boson. We also discuss the constraints from electric dipole moments of electron, neutron and mercury on the viable parameter space mentioned above.

Rotational bands in odd-A Cm and Cf isotopes : exploring the highest neutron orbitals.  

SciTech Connect

Rotational bands have been identified up to high spins ({approx}28{h_bar}) in the odd-A nuclei {sup 247,249}Cm and {sup 249}Cf through inelastic excitation and transfer reactions around the Z=100 region where stability results from shell effects. The [620]1/2 Nilsson configuration in {sup 249}Cm is the highest-lying neutron orbital, from above the N=164 spherical subshell gap, for which high-spin rotational behavior has been established. The data allow for an unambiguous experimental assignment of configurations to the observed bands, unusual for odd-A nuclei near Z=100. The high-spin properties are described in terms of Woods-Saxon cranking calculations.

Systematics of low-lying dipole strengths in odd and even Dy and Gd isotopes  

SciTech Connect

Photon scattering experiments on the odd, deformed nuclei {sup 161,163}Dy and {sup 157}Gd provided detailed information on the excitation energies and transition probabilities of low-lying dipole excitations. In the case of the even-even nuclei {sup 162,164}Dy in addition spins and parities of the excited states could be determined model independently by measuring the angular distributions and the linear polarization of the scattered photons using a Compton polarimeter. The results are compared with the systematics obtained for the neighboring even-even isotopes {sup 160}Dy and {sup 156,158,160}Gd in previous photon scattering experiments. Whereas in the odd Dy isotopes a concentration of dipole strength is observed, which fits nicely into the systematics of the orbital {ital M}1 mode, the dipole strength in {sup 157}Gd is completely fragmented into about 90 transitions.

The global distribution of thermospheric odd nitrogen for solstice conditions during solar cycle minimum  

NASA Technical Reports Server (NTRS)

A two-dimensional model of odd nitrogen in the thermosphere and upper mesosphere is described. The global distributions of nitric oxide and atomic nitrogen are calculated for the solstice period for quiet and moderate magnetic activity during the solar minimum period. The effect of thermospheric transport by winds is investigated along with the importance of particle-induced ionization in the auroral zones. The results are compared with rocket and satellite measurements, and the sensitivity of the model to eddy diffusion and neutral winds is investigated. Downward fluxes of NO into the mesosphere are given, and their importance for stratospheric ozone is discussed. The results show that the summer-to-winter pole meridional circulation transports both NO and N(S-4) across the solar terminator into the polar night region where there is a downward vertical transport toward the mesosphere. The model shows that odd nitrogen densities at high winter latitudes are entirely controlled by particle precipitation and transport processes.

T-odd asymmetry in W + jet events at the LHC.  

PubMed

W bosons produced at high transverse momentum in hadron collisions can have polarization along the direction perpendicular to the production plane, which is odd under naïve T reversal where both the three-momenta and angular momenta are reversed. Perturbative QCD predicts nonzero polarization at the one-loop level, which can be measured as parity-odd components in the angular distribution of charged leptons from the decay of W bosons. We perform a detector-level simulation with the generator MadGraph5_aMC@NLO, and demonstrate that the asymmetry can be observed at the 8 TeV LHC with 20 fb(-1) of data. If confirmed, it will be the first experimental measurement of the sign of the imaginary part of one-loop QCD amplitudes. PMID:25375703

Absolute testing of the reference surface of a Fizeau interferometer through even/odd decompositions.  

PubMed

Absolute testing of spherical surfaces is a technological necessity because of increased accuracy requirements. In a Fizeau setup, the main part of the interferometer deviations thereby comes from the reference surface. We demonstrate the validity of an absolute testing procedure for the reference surface that has been proposed earlier. The procedure relies on the decomposition of the surface deviations into odd and even parts and could be used in partially coherent illumination. The odd deviations are obtained from a basic and a 180 degree-rotated position of an auxiliary sphere, and the even deviations can be measured with the help of a cat's eye position in double pass using an opaque half screen in the interferometer aperture.

In this paper, we report our first attempt at determining NN potentials in the parity odd sector including the spin-orbit force in lattice QCD, employing the method to extract successfully parity even NN potentials from Nambu-Bethe-Salpeter (NBS) wave functions through the Schr\\"odinger equation. Using Nf = 2 CP-PACS gauge configurations on a 16^3 x 32 lattice at a = 0.16 fm and m_\\pi \\cong 1.1 GeV, we calculate central, tensor and spin-orbit potentials in the parity odd sector. Although statistical errors are still large, we observe that the qualitative features of these potentials roughly agree with those of phenomenological potentials.

The negative parity states and some electromagnetic transition properties of even-odd erbium isotopes ({sup 159,161,163,165}Er) were studied within the framework of the interacting boson-fermion model. The single fermion is assumed to be in one of the lh{sub 9/2},3p{sub 3/2},2f{sub 5/2}, and 3p{sub 1/2} single-particle orbits. It was found that the calculated negative parity state energy spectra of the even-odd erbium isotopes agree quite well with the experimental data. The B(E2) values were also calculated and compared with the experimental data.

Realization of the N(odd)-dimensional Quantum Euclidean Space by Differential Operators

The quantum Euclidean space R_{q}^{N} is a kind of noncommutative space which is obtained from ordinary Euclidean space R^{N} by deformation with parameter q. When N is odd, the structure of this space is similar to R_{q}^{3}. Motivated by realization of R_{q}^{3} by differential operators in R^{3}, we give such realization for R_{q}^{5} and R_{q}^{7} cases and generalize our results to R_{q}^{N} (N odd) in this paper, that is, we show that the algebra of R_{q}^{N} can be realized by differential operators acting on C^{infinite} functions on undeformed space R^{N}.

Sensitivity of odd-harmonic amplitudes to open quotient and skewing quotient in glottal airflow.  

PubMed

It is well known that a half-sinusoid has no odd harmonics other than the fundamental. If glottal flow in phonation were to approximate this exact waveshape, which is generally unlikely, some misperception of pitch and loss of vowel intelligibility would occur. The sensitivity of the glottal waveshape to this special shape is explored by systematically varying two parameters, open quotient and skewing quotient. Mild asymmetry (open quotient below 0.45 or above 0.55 and/or skewing quotient greater than 2.0) equalizes the odd-even harmonic series. Singers and speakers avoid the exact symmetry by skewing the flow pulse with source-filter interaction. PMID:25618080

Rotational structure of the odd-proton nuclide 171Tm: A projected shell model study  

NASA Astrophysics Data System (ADS)

Deformed odd-mass nuclei are ideal examples where the interplay between single-particle and collective degrees of freedom can be studied. Inspired by the recent experimental high-spin data in the odd-proton nuclide 171Tm, we perform projected shell model (PSM) calculations to investigate structure of the ground band and other bands based on isomeric states. In addition to the usual quadrupole-quadrupole force in the Hamiltonian, we employ the hexadecapole-hexadecapole (HH) interaction, in a self-consistent way with the hexadecapole deformation of the deformed basis. It is found that the known experimental data can be well described by the PSM calculation. The effect of the HH force on the quasiparticle isomeric states is discussed.

Neighborhood context and immigrant children's physical activity.  

PubMed

Physical activity is an important determinant of obesity and overall health for children, but significant race/ethnic and nativity disparities exist in the amount of physical activity that children receive, with immigrant children particularly at risk for low levels of physical activity. In this paper, we examine and compare patterns in physical activity levels for young children of U.S.-born and immigrant mothers from seven race/ethnic and nativity groups, and test whether physical activity is associated with subjective (parent-reported) and objective (U.S. Census) neighborhood measures. The neighborhood measures include parental-reported perceptions of safety and physical and social disorder and objectively defined neighborhood socioeconomic disadvantage and immigrant concentration. Using restricted, geo-coded Early Childhood Longitudinal Study-Kindergarten (ECLS-K) data (N = 17,510) from 1998 to 1999 linked with U.S. Census 2000 data for the children's neighborhoods, we utilize zero-inflated Poisson (ZIP) models to predict the odds of physical inactivity and expected days of physical activity for kindergarten-aged children. Across both outcomes, foreign-born children have lower levels of physical activity compared to U.S.-born white children. This disparity is not attenuated by a child's socioeconomic, family, or neighborhood characteristics. Physical and social disorder is associated with higher odds of physical inactivity, while perceptions of neighborhood safety are associated with increased expected days of physical activity, but not with inactivity. Immigrant concentration is negatively associated with both physical activity outcomes, but its impact on the probability of physical inactivity differs by the child's race/ethnic and nativity group, such that it is particularly detrimental for U.S.-born white children's physical activity. Research interested in improving the physical activity patterns of minority and second-generation immigrant children should consider how neighborhood context differentially impacts the health and physical activity of children from various racial, ethnic and nativity backgrounds.

The relative odds of lifetime health conditions and infectious diseases among men who have sex with men compared with a matched general population sample.  

PubMed

To address the understudy of health conditions and infectious diseases that are not strictly related to sexual transmission among men who have sex with men (MSM), this study examined the relative odds of 10 health conditions and two infectious diseases in a sample of MSM compared with a matched general population sample. MSM (N = 653) living mainly in Chicago were sampled through successive administrations of an Internet-based survey (2008-2010) that assessed physical and mental health, substance use, and HIV status. Propensity score matching was used to obtain a demographically comparable sample of men (N = 653) from aggregated administrations (2008-2012) of the National Survey on Drug Use and Health. Multivariate Firth logistic regressions compared the odds of ever having been diagnosed with each condition or disease, controlling for demographics, substance use, psychological distress, and HIV/AIDS status. MSM were more likely (p < .01) to have experienced: ulcers (odds ratio [OR] = 2.3), hypertension (OR = 2.1), liver disease (OR = 5.7), and sexually transmitted infections other than HIV/AIDS (OR = 8.9).

The findings suggest that relative to non-sexual-minority men, MSM are more likely to experience a range of health conditions not specifically attributable to HIV/AIDS, sexual behavior, psychological distress, or substance use. The implications for research on the health status and provision of health care to MSM in light of the study findings are considered. PMID:24802608

Odd and even sums of generalized Fibonacci numbers by matrix methods  

NASA Astrophysics Data System (ADS)

For integers A and B, and positive integers n, we define two generalized Fibonacci sequence {gn} and {hn}, respectively, by the recurrence relations gn+1 = Agn+gn-1 and hn+1 = hn+Bhn-1 where g0 = h0 = 0, g1 = h1 = 1. Using a matrix approach, we obtained the odd sum and even sum of the two sequences for all values of A and B.

Test of the Universality of Naive-time-reversal-odd Fragmentation Functions

We investigate the ''spontaneous'' hyperon transverse polarization in $e^+e^-$ annihilation and semi-inclusive deep inelastic scattering processes as a test of the universality of the naive-time-reversal-odd transverse momentum dependent fragmentation functions. We find that universality implies definite sign relations among various observables. This provides a unique opportunity to study initial/final state interaction effects in the fragmentation process and test the associated factorization.

Engineering Escherichia coli for odd straight medium chain free fatty acid production.  

PubMed

Microbial biosynthesis of free fatty acids (FFAs) can be achieved by introducing an acyl-acyl carrier protein thioesterase gene into Escherichia coli. The engineered E. coli usually produced even chain FFAs. In this study, propionyl-CoA synthetase (prpE) from Salmonella enterica was overexpressed in two efficient even chain FFAs producers, ML103 (pXZM12) carrying the acyl-ACP thioesterase gene from Umbellularia californica and ML103 (pXZ18) carrying the acyl-ACP thioesterase gene from Ricinus communis combined with supplement of extracellular propionate. With these metabolically engineered E. coli, the odd straight chain FFAs, undecanoic acid (C11:0), tridecanoic acid (C13:0), and pentadecanoic acid (C15:0) were produced from glucose and propionate. The highest total odd straight chain FFAs produced by ML103 (pXZM12, pBAD-prpE) reached 276 mg/l with a ratio of 23.43 % of the total FFAs. In ML103 (pXZ18, pBAD-prpE), the highest total odd straight chain FFAs accumulated to 297 mg/l, and the ratio reached 17.68 % of the total FFAs. Due to the different substrate specificity of the acyl-ACP thioesterases, the major odd straight chain FFA components of ML103 (pXZM12, pBAD-prpE) were undecanoic acid and tridecanoic acid, while the ML103 (pXZ18, pBAD-prpE) preferred pentadecanoic acid.

Odd-frequency pairing and Ising spin susceptibility in time-reversal-invariant superfluids and superconductors  

NASA Astrophysics Data System (ADS)

We here illustrate the relation between odd-frequency spin-triplet even-parity (OTE) Cooper pairs and anomalous surface magnetic response in time-reversal-invariant (TRI) spin-triplet superfluids and superconductors. The spin susceptibility generally consists of two contributions: even-frequency odd-parity pair amplitudes and odd-frequency even-parity pair amplitudes. The OTE pair amplitudes are absent in the bulk region, but ubiquitously exist in the surface and interface region as Andreev bound states. We here clarify that additional discrete symmetries, originating from the internal symmetry and point-group symmetry, impose strong constraint on the OTE pair amplitudes emergent in the surface of TRI superfluids and superconductors. As a result of the symmetry constraint, the magnetic response of the OTE pairs yields Ising-like anisotropy. For the topological phase of the 3He -B in a restricted geometry, the coupling of the OTE pair amplitudes to an applied field is prohibited by an additional discrete symmetry. Once the discrete symmetry is broken, however, the OTE pairs start to couple to the applied field, which anomalously enhances surface spin susceptibility. Furthermore, we extend this theory to TRI superconductors, where the corresponding discrete symmetry is the mirror reflection symmetry.

Coherent quadrupole-octupole modes and split parity-doublet spectra in odd-A nuclei  

SciTech Connect

A collective model describing coherent quadrupole-octupole oscillations and rotations with a Coriolis coupling between the even-even core and the unpaired nucleon is applied to odd nuclei. The particle-core coupling provides a parity-doublet structure of the spectrum, whereas the quadrupole-octupole motion leads to a splitting of the doublet energy levels. The formalism successfully reproduces the split parity-doublet spectra and the attendant B(E1) and B(E2) transition probabilities in a wide range of odd-A nuclei. It provides estimations for the influence of the Coriolis interaction on the collective motion and subsequently for the value of angular momentum projection K on which the spectrum is built. The analysis of the energy splitting and B(E1) transition probabilities between opposite parity counterparts suggests degenerate doublet structures at high angular momenta. The study provides information about the evolution of quadrupole-octupole collectivity in odd-mass nuclei.

LACK OF ANGULAR CORRELATION AND ODD-PARITY PREFERENCE IN COSMIC MICROWAVE BACKGROUND DATA  

SciTech Connect

We have investigated the angular correlation in the recent cosmic microwave background data. In addition to the known large-angle correlation anomaly, we find the lack of correlation at small angles with high statistical significance. We have investigated various non-cosmological contamination as well as the Wilkinson Microwave Anisotropy Probe (WMAP) team's simulated data. However, we have not found a definite cause. In the angular power spectrum of WMAP data, there exists anomalous odd-parity preference at low multipoles. Noting the equivalence between the power spectrum and the correlation, we have investigated the association between the lack of large-angle correlation and the odd-parity preference. From our investigation, we find that the odd-parity preference at low multipoles is, in fact, a phenomenological origin of the lack of large-angle correlation. Further investigation is required to find out whether the origin of the anomaly is cosmological or due to unaccounted systematics. The data from the Planck surveyor, which has systematics distinct from WMAP, will greatly help us to resolve its origin.

On the Gaussian overlap approximation for the collective excitations of odd nuclei  

NASA Astrophysics Data System (ADS)

The multi-dimensional generator coordinate method is applied to describe the quadrupole collective states of odd nuclei. The laboratory Cartesian components of the quadrupole deformation tensor are used as the generator coordinates. The two mean-field states of an odd nucleus constituting a Kramers’ doublet are taken as the two intrinsic generating states which can rotate in the laboratory reference frame. The time-signature invariance of these intrinsic states is assumed. A version of the Gaussian overlap approximation (GOA) for the two generating states is constructed. A system of two coupled differential equations for the collective excitations of odd nuclei is derived from the variational principle using the GOA. The system forms a generalized eigenvalue differential equation in the two-dimensional ‘alispin’ space. Breaking the time-reversal symmetry and alignment of the angular momentum in the mean-field states modifies the rotational part of the Hamiltonian compared to that of the standard Bohr Hamiltonian, whereas the quadrupole vibrations are modified through the coupling of the Kramers states.

Shape phase transition in odd-even nuclei: From spherical to deformed gamma-unstable shapes  

SciTech Connect

Shape phase transitions in odd-A nuclei are investigated within the framework of the interacting boson-fermion model. The case of a single j=9/2 fermion coupled to an even-even boson core is considered. This boson core transits from spherical to gamma-unstable shapes depending on the value of a control parameter in the boson Hamiltonian. The effect of the coupling of the odd particle to this core along the shape transition and, in particular, at the critical point is discussed. For that purpose, the ground-state energy surface in terms of the beta and gamma shape variables for the even core and odd-even energy surfaces for the different K states coming from j=9/2 are constructed. The evolution of each individual coupled state along the transition from the spherical [U(5)] to the gamma-unstable [O(6)] situation is investigated. One finds that the core-fermion coupling gives rise to a smoother transition than in the even-core case.

On the relationship of gerbes to the odd families index theorem  

NASA Astrophysics Data System (ADS)

The goal of this paper is to apply the universal gerbe of [A. Carey, J. Mickelsson, A gerbe obstruction to quantization of fermions on odd dimensional manifolds, Lett. Math. Phys. 51 (2000) 145-160] and [A.L. Carey, J. Mickelsson, The universal gerbe, Dixmier-Douady classes and gauge theory, Lett. Math. Phys. 59 (2002) 47-60] to give an alternative, simple and more unified view of the relationship between index theory and gerbes. We discuss determinant bundle gerbes [A. Carey, J. Mickelsson, M. Murray, Index theory, gerbes, and Hamiltonian quantization, Comm. Math. Phys. 183 (1997) 707-722] and the index gerbe of [J. Lott, Higher-degree analogs of the determinant line bundle, Comm. Math. Phys. 230 (1) (2002) 41-69] for the case of families of Dirac operators on odd dimensional closed manifolds. The method also works for a family of Dirac operators on odd dimensional manifolds with boundary, for a pair of Melrose and Piazza's Cl(1)-spectral sections for a family of Dirac operators on even dimensional closed manifolds with vanishing index in K-theory and, in a simple case, for manifolds with corners. The common feature of these bundle gerbes is that there exists a canonical bundle gerbe connection whose curving is given by the degree 2 part of the even eta form (up to a locally defined exact form) arising from the local family index theorem.

Charge radii of odd-A191-211Po isotopes  

NASA Astrophysics Data System (ADS)

Isotope shifts have been measured for the odd-A polonium isotopes 191-211Po and changes in the nuclear mean square charge radii ? have been deduced. The measurements were performed at CERN-ISOLDE using the in-source resonance-ionization spectroscopy technique. The combined analysis of these data and our recent results for even-A polonium isotopes indicates an onset of deformation already at 197,198Po, when going away from stability. This is significantly earlier than was suggested by previous theoretical and experimental studies of the polonium isotopes. Moreover and in contrast to the mercury isotopes, where a strong odd-even staggering of the charge radii of the ground states was observed by approaching the neutron mid-shell at N=104, no such effect is present in polonium down to 191Po. Consequently the charge radii of both isomeric and ground states of the odd-A polonium isotopes follow the same trend as the even-A isotopes.

Mean-field description of odd-frequency superconductivity with staggered ordering vector  

NASA Astrophysics Data System (ADS)

A low-energy fixed-point Hamiltonian is constructed for the s-wave odd-frequency pairing state with staggered ordering vector in the two-channel Kondo lattice. The effective model is justified because it reproduces low-energy behaviors of self-energy obtained by the dynamical mean-field theory. The retardation effect is essential for the odd-frequency pairing, which comes from the hybridization process between conduction electrons and pseudofermions originating from localized spins at low energies. Using the effective Hamiltonian, the electromagnetic response functions are microscopically calculated. The present system shows a "weak" Meissner effect, where both paramagnetic and diamagnetic parts contribute to the Meissner kernel to give a small total diamagnetic response in the superconducting state. This feature is in contrast to the ordinary s-wave BCS pairing where only the diamagnetic kernel is finite in the ground state. The staggered nature of the odd-frequency order parameter plays an important role for the sign of the Meissner kernel.

Relationship of peroxyacetyl nitrate to active and total odd nitrogen at northern high latitudes - Influence of reservoir species on NO(x) and O3  

NASA Technical Reports Server (NTRS)

The partitioning of relative nitrogen in the Arctic and the sub-Arctic troposphere based on measurements conducted during the 1988 Arctic Boundary Layer Expedition (ABLE 3A) is described. The first set of comprehensive odd nitrogen and O3 measurements from the Arctic/sub-Arctic free troposphere shows that a highly aged air mass that has persisted under very cold conditions is present. A large fraction of the odd nitrogen appears to be present in the form of reservoir species such as PAN. Significant quantities of as yet unknown reactive nitrogen species, such as complex alkyl nitrates and pernitrates, are expected to be present. Together with PAN, these nitrate and pernitrate reservoir species could control the entire NO(x) availability of the high-latitude troposphere and in turn influence the O3 photochemistry of the region. The role of PAN in influencing the O3 reservoir is shown to be important and may be responsible for the increasing O3 temporal trend observed at high latitudes.

Sexual victimization of youth with a physical disability: an examination of prevalence rates, and risk and protective factors.  

PubMed

Children with disabilities have been shown to be at greater risk of victimization than those without. Although much of the research combines disability of any type into a single disability category, recent evidence suggests that not all types of disabilities are equally associated with victimization. To date, little knowledge exists about the victimization of youth with physical disabilities. This study used data from a national school-based survey of adolescents (n = 6,749, mean age = 15.41, SD = .66) in Switzerland to investigate sexual victimization (SV) among physically disabled youth. Two subtypes of SV were differentiated: contact SV, including penetration or touching/kissing, and non-contact SV, such as exhibitionism, verbal harassment, exposure to sexual acts, or cyber SV. A total of 360 (5.1%) youth self-identified as having a physical disability. Lifetime prevalence rates for contact SV were 25.95% for girls with a physical disability (odds ratio [OR] = 1.29 compared with able-bodied girls), 18.50% for boys with physical disability (OR = 2.78 compared with able-bodied boys), and 22.35% for the total sample with physical disability (OR = 1.74 compared with able-bodied youth). For non-contact SV, the lifetime prevalence was 48.11% for girls with a physical disability (OR = 1.44 compared with able-bodied girls), 31.76% for boys with physical disability (OR = 1.95 compared with able-bodied boys), and 40.28% for the total sample with physical disability (OR = 1.67 compared with able-bodied youth). After controlling for other risk factors, physical disability was a significant predictor of contact and non-contact SV for boys, but not for girls. PMID:24870960

An Annotated Catalog of Inverted Repeats of Caenorhabditis elegans Chromosomes III and X, with Observations Concerning Odd/Even Biases and Conserved Motifs  

PubMed Central

We have taken a computational approach to the problem of discovering and deciphering the grammar and syntax of gene regulation in eukaryotes. A logical first step is to produce an annotated catalog of all regulatory sites in a given genome. Likely candidates for such sites are direct and indirect repeats, including three subcategories of indirect repeats: inverted (palindromic), everted, and mirror-image repeats. To that end we have produced a searchable database of inverted repeats of chromosomes III and X of Caenorhabditis elegans, the first completely sequenced multicellular eukaryote. Initial results from the use of this catalog are observations concerning odd/even biases in perfect IRs. The potential usefulness of the catalog as a discovery tool for promoters was shown for some of the genes involved with G-protein functions and for heat shock protein 104 (hsp104). PMID:10984456

PARAMETRIC TENSION BETWEEN EVEN AND ODD MULTIPOLE DATA OF THE WMAP POWER SPECTRUM: UNACCOUNTED CONTAMINATION OR MISSING PARAMETERS?  

SciTech Connect

There exists power contrast in even and odd multipoles of the WMAP power spectrum at low and intermediate multipole ranges. This anomaly is explicitly associated with the angular power spectrum, which is heavily used for cosmological model fitting. Having noted this, we have investigated whether even (odd) multipole data set is individually consistent with the WMAP concordance model. Our investigation shows that the WMAP concordance model does not make a good fit for even (odd) multipole data set, which indicates parametric tension between even and odd multipole data set. Noting that tension is highest in primordial power spectrum parameters, we have additionally considered a running spectral index, but found that tension increases to even a higher level. We believe these parametric tensions may be indications of unaccounted contamination or imperfection of the model.

Development of the quantum theory of T-odd asymmetries for prescission and evaporated third particles in ternary nuclear fission induced by cold polarized neutrons  

NASA Astrophysics Data System (ADS)

A comparative analysis of the results obtained by experimentally and theoretically studying T-odd asymmetries for various third particles in the true and delayed ternary nuclear fission induced by cold polarized neutrons was performed. It was confirmed that the appearance of these asymmetries was associated with the effect of rotation of a polarized system undergoing fission on the angular distributions of prescission and evaporated third particles with respect to the direction along which the emerging fission fragments flew apart, this effect being determined by the Coriolis interaction of the rotational and the internalmotion of the fissioning system. A quantum-mechanical description of particle motion in a rotating coordinate system was generalized to the case where gamma-ray emission was present. It was shown that the separation of the motions of an axially symmetric fissile system into a rotational and an internal motion was valid in the external region as well, where ternary-fission products had already been formed, if it was considered that the motion of fission fragments was tightly connected with the system symmetry axis, which rotated in the laboratory frame. It was found that the dependence of the fissile-system moment of inertia appearing in the Coriolis interaction Hamiltonian on the distance between the fission fragments flying apart generated an additional phase in the amplitude of the radial distribution of fission fragments. It was shown that this phase might change sizably the contribution of the interference between fission amplitudes of neutron resonances excited in a fissile compound nucleus to the absolute values of T -odd asymmetries, especially for third particles such as neutrons and photons, which interacted only slightly with fission fragments.

The Link between Peer Relations, Prosocial Behavior, and ODD/ADHD Symptoms in 7–9-Year-Old Children  

PubMed Central

Oppositional defiant disorder (ODD) and attention-deficit/hyperactivity disorder (ADHD) are characterized by symptoms that hinder successful positive interaction with peers. The main goal of this study was to examine if the presence of symptoms of ODD and ADHD affects the relationship between positive social behavior and peer status found in 7–9-year-old children who show symptoms typical of ADHD and/or ODD. Furthermore, the possible interaction with sex was investigated. We used data collected in the first wave of The Bergen Child Study of mental health (BCS), a prospective longitudinal total population study of children's developmental and mental health. The target population consisted of children in the second to the fourth, in all public, private, and special schools in Bergen, Norway, in the fall of 2002 (N = 9430). All 79 primary schools in Bergen participated in the study. Both teacher (8809 complete cases) and parent (6253 complete cases) report were used in the analyses. ADHD and ODD scores were estimated using the Swanson Noland and Pelham rating scale version IV (SNAP-IV), and peer problems and prosocial behavior were assessed using the Strengths and Difficulties Questionnaire (SDQ). We replicated the relationship between peer problems and prosocial behavior found previously in typically developing children. Our results showed that the relationship between peer problems and prosocial behavior became weaker as the ODD symptoms increased in number and severity. For ADHD this effect was only found in the teacher report of the children. A sex effect for ODD symptoms was found only using the parent report: boys with ODD symptoms showed less prosocial behavior than girls with similar levels of ODD symptoms. Since this effect was not found using the teacher data, it may imply a situational effect (school/home) for girls with high levels of ODD. The moderator effect of ODD/ADHD was comparable for boys and girls. Our findings suggest that even if children with ADHD/ODD symptoms have the opportunity to practice their social skills in peer relationships, this is not necessarily accompanied by an increase in prosocial behavior.

Biological pattern and transcriptomic exploration and phylogenetic analysis in the odd floral architecture tree: Helwingia willd  

PubMed Central

Background Odd traits in few of plant species usually implicate potential biology significances in plant evolutions. The genus Helwingia Willd, a dioecious medical shrub in Aquifoliales order, has an odd floral architecture-epiphyllous inflorescence. The potential significances and possible evolutionary origin of this specie are not well understood due to poorly available data of biological and genetic studies. In addition, the advent of genomics-based technologies has widely revolutionized plant species with unknown genomic information. Results Morphological and biological pattern were detailed via anatomical and pollination analyses. An RNA sequencing based transcriptomic analysis were undertaken and a high-resolution phylogenetic analysis was conducted based on single-copy genes in more than 80 species of seed plants, including H. japonica. It is verified that a potential fusion of rachis to the leaf midvein facilitates insect pollination. RNA sequencing yielded a total of 111450 unigenes; half of them had significant similarity with proteins in the public database, and 20281 unigenes were mapped to 119 pathways. Deduced from the phylogenetic analysis based on single-copy genes, the group of Helwingia is closer with Euasterids II and rather than Euasterids, congruent with previous reports using plastid sequences. Conclusions The odd flower architecture make H. Willd adapt to insect pollination by hosting those insects larger than the flower in size via leave, which has little common character that other insect pollination plants hold. Further the present transcriptome greatly riches genomics information of Helwingia species and nucleus genes based phylogenetic analysis also greatly improve the resolution and robustness of phylogenetic reconstruction in H. japonica.

Néel-XXZ state overlaps: odd particle numbers and Lieb-Liniger scaling limit  

NASA Astrophysics Data System (ADS)

We specialize a recently-proposed determinant formula (Brockmann, De Nardis, Wouters and Caux 2014 J. Phys. A: Math. Theor. 47 145003) for the overlap of the zero-momentum Néel state with Bethe states of the spin-1/2 XXZ chain to the case of an odd number of downturned spins, showing that it is still of ‘Gaudin-like’ form, similar to the case of an even number of down spins. We generalize this result to the overlap of q-raised Néel states with parity-invariant Bethe states lying in a nonzero magnetization sector. The generalized determinant expression can then be used to derive the corresponding determinants and their prefactors in the scaling limit to the Lieb-Liniger (LL) Bose gas. The odd number of down spins directly translates to an odd number of bosons. We furthermore give a proof that the Néel state has no overlap with non-parity-invariant Bethe states. This is based on a determinant expression for overlaps with general Bethe states that was obtained in the context of the XXZ chain with open boundary conditions (Pozsgay 2013 arXiv:1309.4593, Kozlowski and Pozsgay 2012 J. Stat. Mech. P05021, Tsuchiya 1998 J. Math. Phys. 39 5946). The statement that overlaps with non-parity-invariant Bethe states vanish is still valid in the scaling limit to LL which means that the Bose-Einstein condensate state (De Nardis, Wouters, Brockmann and Caux 2014 Phys. Rev. A 89 033601) has zero overlap with non-parity-invariant LL Bethe states.

Early-life predictors of leisure-time physical inactivity in midadulthood: findings from a prospective british birth cohort.  

PubMed

Much adult physical inactivity research ignores early-life factors from which later influences may originate. In the 1958 British birth cohort (followed from 1958 to 2008), leisure-time inactivity, defined as activity frequency of less than once a week, was assessed at ages 33, 42, and 50 years (n = 12,776). Early-life factors (at ages 0-16 years) were categorized into 3 domains (i.e., physical, social, and behavioral). We assessed associations of adult inactivity 1) with factors within domains, 2) with the 3 domains combined, and 3) allowing for adult factors. At each age, approximately 32% of subjects were inactive. When domains were combined, factors associated with inactivity (e.g., at age 50 years) were prepubertal stature (5% lower odds per 1-standard deviation higher height), hand control/coordination problems (14% higher odds per 1-point increase on a 4-point scale), cognition (10% lower odds per 1-standard deviation greater ability), parental divorce (21% higher odds), institutional care (29% higher odds), parental social class at child's birth (9% higher odds per 1-point reduction on a 4-point scale), minimal parental education (13% higher odds), household amenities (2% higher odds per increase (representing poorer amenities) on a 19-point scale), inactivity (8% higher odds per 1-point reduction in activity on a 4-point scale), low sports aptitude (13% higher odds), and externalizing behaviors (i.e., conduct problems) (5% higher odds per 1-standard deviation higher score). Adjustment for adult covariates weakened associations slightly. Factors from early life were associated with adult leisure-time inactivity, allowing for early identification of groups vulnerable to inactivity. PMID:25282383

Odds of fault and factors for out-of-state drivers in crashes in four states of the USA.  

PubMed

Drivers outside their country of residence are at a safety disadvantage when compared to native counterparts. This research aimed to (1) investigate if out-of-state drivers in the United States experienced the same vulnerabilities as foreign drivers, and (2) examine the relations of out-of-state crashes to various human and environmental factors. Crash data from Florida, Maine, Minnesota, and Nevada was analyzed to model fault using logistic regressions. Univariate regressions showed that out-of-state drivers had increased odds of fault, ranging from 17% to 92%, for a single-vehicle crash compared to in-state drivers in all states except Florida, where there was no difference between groups. Odds were elevated for out-of-state drivers in two-vehicle crashes by 3% to 19% in all states except Florida and Minnesota, where, again, there was no difference between groups. Human and environmental factors such as age, sex, driving conditions, and seasons were examined with multivariate regressions for in- and out-of-state groups separately, and their odds ratios were compared. For single-vehicle crashes age, sex, road grade, surface condition, light conditions, and day of week were factors that increased at least one of the two groups' odds of fault in all states. Sex, surface condition, and light conditions increased the odds of fault for at least one of the groups in two-vehicle crashes in all four states. Factors that consistently increased odds of fault for both single- and two-vehicle crashes were males, non-vehicle owners, curves, and inclement weather. Although there were several factors in each state that increased odds of fault for out-of-state drivers, no factors consistently increased odds of fault for out-of-state drivers across all four states.

Importance of trends in the interpretation of an overall odds ratio in the meta-analysis of clinical trials.  

PubMed

This paper contains a proposition related to the publication of meta-analyses of clinical trials. We consider the situation where the results of a number of trials are summarized by a common or typical odds ratio. We show that stating such an odds ratio as the summary of evidence from a number of trials can be misleading if certain systematic differences between trials exist. In such cases the author should state not just one odds ratio but also its dependence on the relevant characteristics of the trials. In particular, we propose that those reporting a meta-analysis state in advance a (limited) number of variables to be considered for potential interaction with the exposure (risk factor or treatment) of interest. The list might include centre size and the odds in the placebo or control group if such an effect is a priori clinically plausible. The trials should be ordered according to each of these variables and a trend test for the odds ratio should be computed. Apart from a 'genuine' effect, an appreciable interaction could also be indicative of the (multiplicative) odds ratio being an inappropriate measure for the particular meta-analysis. Without any consideration as to the possibility of interaction, the meta-analysis should be considered incomplete. If such an interaction exists, the odds ratio should be stated as a function of the interacting variable, either as a formula or (preferably) in a table stating the odds ratio for a number of different values of the interacting variable, and not as a single summary statistic.

Development of odd-Z-projectile reactions for transactinide element synthesis  

SciTech Connect

The development of new odd-Z-projectile reactions leading to the production of transactinide elements is described. The cross section of the even-Z-projectile 208Pb(64Ni, n)271Ds reaction was measured at two new energies using the Berkeley Gas-filled Separator at the Lawrence Berkeley National Laboratory 88-Inch Cyclotron. In total, seven decay chains attributable to 271Ds were observed. These data, combined with previous results, establish an excitation function for the production of 271Ds. The maximum cross section was 20 +15 -11 pb at a center-of-target energy of 311.5 MeV in the laboratory frame.The data from the 271Ds experiments were used to estimate the optimum beam energy for the new odd-Z-projectile 208Pb(65Cu, n)272-111 reaction using the Fusion by Diffusion theory proposed by Swiatecki, Siwek-Wilczynska, and Wilczynski. A cross section for this reaction was measured for the first time, at a center-of-target energy of 321.1 MeV in the laboratory frame. The excitation energy f or compound nuclei formed at the target center was 13.2 MeV. One decay chain was observed, resulting in a measured cross section of 1.7 +3.9 -1.4 pb. This decay chain is in good agreement with previously published data on the decay of 272-111.The new odd-Z-projectile 208Pb(55Mn, n)262Bh reaction was studied at three different projectile energies, and 33 decay chains of 262Bh were observed. The existence of a previously reported alpha-decaying isomeric state in this nuclide was confirmed. Production of the ground state was preferred at all three beam energies. The maximum cross section was 540 +180 -150 pb at a projectile center-of-target energy of 264.0 MeV. This cross section is much larger than that previously reported for the even-Z-projectile 209Bi(54Cr, n)262Bh reaction, which may be because the 54Cr projectile energies in the latter reaction were too high for optimum production of the 1n product. At the highest projectile energy of 268.0 MeV in the target center, two decay chains from 261Bh were observed as a result of the 208Pb(55Mn, 2n) reaction. In summary, this work shows that odd-Z-projectile reactions can have cross sections comparable to analogous even-Z-projectile reactions, and that the energy of the maximum cross section for 1n reactions can be estimated simply.

Systematics of fine structure in the ? decay of deformed odd-mass nuclei  

NASA Astrophysics Data System (ADS)

We present a detailed analysis of the a-decay fine structure in 32 deformed odd-mass nuclei from Z = 93 to Z = 102. The ?-decay half-lives are systematically calculated within the multichannel cluster model (MCCM), which turns out to well reproduce the experimental data and show the neutron deformed shell structure. The branching ratios for various daughter states are investigated in the MCCM and in the WKB barrier penetration approach, respectively. It is found that the MCCM results agree well with the experimental data, while the WKB results have relatively large deviations from the experimental data for the ? transitions to the high-lying members of the rotational band.

We employ a rooted staggered discretization and study lattice spacings down to 0.1 fm and Goldstone pion masses around 480 MeV. In order to deal with a positive measure, we consider purely imaginary electric fields and real magnetic fields, and then exploit the analytic continuation.

Evolution of odd A transitional iridium nuclei at the strong deformation limit levels of $\\^{185}$Ir

A level scheme is proposed for neutron deficient /sup 185/Ir obtained by the decay of /sup 185/Pt produced with the ISOLDE on-line separator (CERN). This level scheme is compared to those of heavier mass iridium nuclei where the negative parity levels had been interpreted in the asymmetric-rotor-plus-particle model. In /sup 185/Ir similar systems of levels appear with a stronger prolate deformation of the nucleus. They seem correctly described by coupling an odd-particle (or a hole) to a symmetric rotor.

Parallel FE Approximation of the Even/Odd Parity Form of the Linear Boltzmann Equation  

SciTech Connect

A novel solution method has been developed to solve the linear Boltzmann equation on an unstructured triangular mesh. Instead of tackling the first-order form of the equation, this approach is based on the even/odd-parity form in conjunction with the conventional mdtigroup discrete-ordinates approximation. The finite element method is used to treat the spatial dependence. The solution method is unique in that the space-direction dependence is solved simultaneously, eliminating the need for the conventional inner iterations, and the method is well suited for massively parallel computers.

Lack of motor prediction, rather than perceptual conflict, evokes an odd sensation upon stepping onto a stopped escalator  

PubMed Central

When stepping onto a stopped escalator, we often perceive an “odd sensation” that is never felt when stepping onto stairs. The sight of an escalator provides a strong contextual cue that, in expectation of the backward acceleration when stepping on, triggers an anticipatory forward postural adjustment driven by a habitual and implicit motor process. Here we contrast two theories about why this postural change leads to an odd sensation. The first theory links the odd sensation to a lack of sensorimotor prediction from all low-level implicit motor processes. The second theory links the odd sensation to the high-level conflict between the conscious awareness that the escalator is stopped and the implicit perception that evokes an endogenous motor program specific to a moving escalator. We show very similar postural changes can also arise from reflexive responses to visual stimuli, such as contracting/expanding optic flow fields, and that these reflexive responses produce similar odd sensations to the stopped escalator. We conclude that the high-level conflict is not necessary for such sensations. In contrast, the implicitly driven behavioral change itself essentially leads to the odd sensation in motor perception since the unintentional change may be less attributable to self-generated action because of a lack of motor predictions.

It does not look odd to me: Perceptual impairments and eye movements in amnesic patients with medial temporal lobe damage  

PubMed Central

Studies of people with memory impairments have shown that a specific set of brain structures in the medial temporal lobe (MTL) is vital for memory function. However, whether these structures have a role outside of memory remains contentious. Recent studies of amnesic patients with damage to two structures within the MTL, the hippocampus and the perirhinal cortex, indicated that these patients also performed poorly on perceptual tasks. More specifically, they performed worse than controls when discriminating between objects, faces and scenes with overlapping features. In order to investigate whether these perceptual deficits are reflected in their viewing strategies, we tested a group of amnesic patients with MTL damage that included the hippocampus and perirhinal cortex on a series of oddity discrimination tasks in which they had to select an odd item from a visual array. Participants' eye movements were monitored throughout the experiment. Results revealed that patients were impaired on tasks that required them to discriminate between items that shared many features, and tasks that required processing items from different viewpoints. An analysis of their eye movements revealed that they exhibited a similar viewing pattern as controls: they fixated more on the target item on trials answered correctly, but not on trials answered incorrectly. In addition, their impaired performance was not explained by an abnormal viewing-strategy that assessed their use of working memory. These results suggest that the perceptual deficits in the MTL patients are not a consequence of abnormal viewing patterns of the objects and scenes, but instead, could involve an inability to bind information gathered from several fixations into a cohesive percept. These data also support the view that MTL structures are important not only for long-term memory, but are also involved in perceptual tasks. PMID:23154380

On the representation of even numbers as the sum and difference of two primes and the representation of odd numbers as the sum of an odd prime and an even semiprime and the distribution of primes in short intervals  

E-print Network

The representation of even numbers as the sum of two primes and the distribution of primes in short intervals were investigated and a main theorem was given out and proved, which states: For every number $n$ greater than a positive number $n_{0}$, let $q$ be an odd prime number smaller than $\\sqrt{2n}$ and $d=2n-q$, then there is always at least an odd number $d$ which does not contain any prime factor smaller than $\\sqrt{2n}$ and must be an odd prime number greater than $2n-\\sqrt{2n}$. Then it was proved that for every number $n$ greater than 1, there are always at least a pair of primes $p$ and $q$ which are symmetrical about the number $n$ so that even numbers greater than 2 can be expressed as the sum of two primes. Hence, the Goldbach's conjecture was proved. Also theorems of the distribution of primes in short intervals were given out and proved. By these theorems, the Legendre's conjecture, the Oppermann's conjecture, the Hanssner's conjecture, the Brocard's conjecture, the Andrica's conjecture, the Sierpinski's conjecture and the Sierpinski's conjecture of triangular numbers were proved and the Mills' constant can be determined. The representation of odd numbers as the sum of an odd prime number and an even semiprime was investigated and a main theorem was given out and proved, which states: For every number $n$ greater than a positive number $n_{0}$, let $q$ be an odd prime number smaller than $\\sqrt{2n}$ and $d=2n+1-2q$, then there is always at least an odd number $d$ which does not contain any odd prime factor smaller than $\\sqrt{2n}$ and must be a prime number greater than $2n+1-2\\sqrt{2n}$. Then it was proved that for every number $n$ greater than 2, there are always at least a pair of primes $p$ and $q$ so that all odd integers greater than 5 can be represented as the sum of an odd prime number and an even semiprime. Hence, the Lemoine's conjecture was proved.

Cosmology and New Physics  

E-print Network

A comparison of the standard models in particle physics and in cosmology demonstrates that they are not compatible, though both are well established. Basics of modern cosmology are briefly reviewed. It is argued that the measurements of the main cosmological parameters are achieved through many independent physical phenomena and this minimizes possible interpretation errors. It is shown that astronomy demands new physics beyond the frameworks of the (minimal) standard model in particle physics. More revolutionary modifications of the basic principles of the theory are also discussed.

Nonlinear and Perturbative Evolution of Distorted Black Holes. II. Odd-parity Modes  

E-print Network

We compare the fully nonlinear and perturbative evolution of nonrotating black holes with odd-parity distortions utilizing the perturbative results to interpret the nonlinear results. This introduction of the second polarization (odd-parity) mode of the system, and the systematic use of combined techniques brings us closer to the goal of studying more complicated systems like distorted, rotating black holes, such as those formed in the final inspiral stage of two black holes. The nonlinear evolutions are performed with the 3D parallel code for Numerical Relativity, {Cactus}, and an independent axisymmetric code, {Magor}. The linearized calculation is performed in two ways: (a) We treat the system as a metric perturbation on Schwarzschild, using the Regge-Wheeler equation to obtain the waveforms produced. (b) We treat the system as a curvature perturbation of a Kerr black hole (but here restricted to the case of vanishing rotation parameter a) and evolve it with the Teukolsky equation The comparisons of the waveforms obtained show an excellent agreement in all cases.

Very light CP-odd scalar in the Two-Higgs-Doublet Model  

E-print Network

We show that a general two-Higgs-doublet model (THDM) with a very light CP-odd scalar (A) can be compatible with the rho parameter, Br(b --> s\\gamma), R_b, A_b, (g-2) of muon, Br(Upsilon --> A gamma), and the direct search via the Yukawa process at LEP. For its mass around 0.2 GeV, the muon (g-2) and Br(Upsilon --> A \\gamma) data require tan(beta) to be about 1. Consequently, A can behave like a fermiophobic CP-odd scalar and predominantly decay into a photon pair ("gamma gamma"), which registers in detectors of high energy collider experiments as a single photon signature when the momentum of A is large. We compute the partial decay width of Z --> A A A and the production rate of f \\bar{f} --> Z A A --> Z +"gamma gamma", f^' {\\bar f} --> W^{\\pm} A A --> W^\\pm + "gamma gamma" and f \\bar f --> H^+ H^- --> W^+ W^- A A --> W^+ W^- + "gamma gamma" at high energy colliders such as LEP, Tevatron, LHC, and future Linear Colliders. Other production mechanisms of a light A, such as gg --> h --> AA --> "gamma gamma", are also discussed.

Large odd-even staggering in the very light platinum isotopes from laser spectroscopy  

SciTech Connect

Laser spectroscopy measurements have been carried out on very neutron-deficient platinum isotopes with the COMPLIS experimental set-up on line with the ISOLDE-Booster facility. For the first time, Hg {alpha}-decay was exploited to extend the very light platinum chain. Using the 5d{sup 9}6s {sup 3}D{sub 3}{yields}5d{sup 9}6p {sup 3}P{sub 2} optical transition, hyperfine spectra of {sup 182,181,180,179,178}Pt and {sup 183}Pt{sup m} were recorded for the first time. The variation of the mean square charge radius between these nuclei, the magnetic moments of the odd isotopes and the quadrupole moment of {sup 183}Pt{sup m} were thus measured. A large deformation change between {sup 183}Pt{sup g} and {sup 183}Pt{sup m}, an odd-even staggering of the charge radius and a deformation drop from A=179 are clearly observed. All these results are discussed and compared with microscopic theoretical predictions using Hartree-Fock-Bogolyubov calculations using the Gogny force.

Neutron Single Particle States and Isomers in Odd Mass Nickel Isotopes Near 78NI  

NASA Astrophysics Data System (ADS)

A decay spectroscopy experiment was performed at the National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University (MSU) to measure the lowenergy excited states in 71-75Ni populated via the ?-decay of 71-75Co. Data collected from this experiment provided enough statistics to establish ?-? coincidence relations leading to partial level schemes for 71Ni and 73Ni. The main goal of this experiment was to investigate the changes in excitation energy of the 5/2- state relative to 9/2+ ground state as well as search for the 1/2- isomeric state in odd-mass nickel isotopes approaching 78Ni. Systematics in shell model calculations using realistic interactions for odd mass 69-77Ni reveal a steady increase in energy spacing between the 1/2- level and 9/2+ ground state but an almost constant energy separation between the 5/2- and 1/2- excited states. In this experiment the positions of the 5/2- states in 71Ni and 73Ni have tentatively been established.

Effects of Odd-Z Projectiles on Fusion-Evaporation Cross Sections  

NASA Astrophysics Data System (ADS)

The production of nuclides near the N=126 shell in the ^45Sc + ^159Tb, ^162Dy reactions has been studied at Texas A&M University using the MARS spectrometer. Previously measured 4n exit channel cross sections for the ^48Ca, ^50Ti + ^159Tb and ^48Ca + ^162Dy reactions have exhibited enhanced fission probabilities in the de-excitation of the compound nucleus due to collective enhancements to the fission level density. The current research intends to study the change in the evaporation residue cross sections when odd-Z projectiles react with the same targets. The maximum 4n cross sections of the ^45Sc + ^159Tb, ^162Dy reactions were 2 ?b, and 4 ?b respectively, and these data are several orders of magnitude smaller than both theoretical predictions and the experimental data for the ^48Ca and ^50Ti reactions discussed above. This can be explained by collective enhancements as well as the relative neutron deficiency of ^45Sc compared to ^48Ca and ^50Ti. This talk will discuss theoretical models of evaporation residue cross sections, and will discuss the latest results on excitation functions for odd-Z projectiles reacting with lanthanide targets. This work may also have relevance to the production of superheavy elements with Z 118.

Calculation of $P_ and $T_ odd effects in $"" sup 205_TIF including electron correlation  

E-print Network

A method and codes for two-step correlation calculation of heavy-atom molecules have been developed, employing the generalized relativistic effective core potential and relativistic coupled cluster (RCC) methods at the first step, followed by nonvariational one-center restoration of proper four-component spinors in the heavy cores. Electron correlation is included for the first time in an ab initio calculation of the interaction of the permanent P,T-odd proton electric dipole moment with the internal electromagnetic field in a molecule. The calculation is performed for the ground state of TlF at the experimental equilibrium, R_e=2.0844 A, and at R=2.1 A, with spin-orbit and correlation effects included by RCC. Calculated results with single cluster amplitudes only are in good agreement (3% and 1%) with recent Dirac-Hartree-Fock (DHF) values of the magnetic parameter M; the larger differences occurring between present and DHF volume parameter (X) values, as well as between the two DHF calculations, are explained. Inclusion of electron correlation by GRECP/RCC with single and double excitations has a major effect on the P,T-odd parameters, decreasing M by 17% and X by 22%.

Sun's retrograde motion and violation of even-odd cycle rule in sunspot activity  

E-print Network

The sum of sunspots number over an odd numbered 11 yr sunspot cycle exceeds that of its preceding even numbered cycle, and it is well known as Gnevyshev and Ohl rule (or G--O rule) after the names of the authors who discovered it in 1948. The G--O rule can be used to predict the sum of sunspot numbers of a forthcoming odd cycle from that of its preceding even cycle. But this is not always possible because occasionally the G--O rule is violated. So far no plausible reason is known either for the G--O rule or the violation of this rule. Here we showed the epochs of the violation of the G--O rule are close to the epochs of the Sun's retrograde orbital motion about the centre of mass of the solar system (i.e., the epochs at which the orbital angular momentum of the Sun is weakly negative). Using this result easy to predict the epochs of violation of the G--O rule well in advance. We also showed that the solar equatorial rotation rate determined from sunspot group data during the period 1879--2004 is correlated/anti-correlated to the Sun's orbital torque during before/after 1945. We have found the existence of a statistically significant $\\sim$ 17 yr periodicity in the solar equatorial rotation rate. The implications of these findings for understanding the mechanism behind the solar cycle and the solar-terrestrial relationship are discussed.

Negative parity low-spin states of even-odd 187-197Pt isotopes  

NASA Astrophysics Data System (ADS)

In this paper, the negative parity low-spin states of even-odd 187-197Pt isotopes have been studied within the framework of the Interacting Boson-Fermion Model (IBFM-1). The single fermion is assumed to be in one of the 2 f 5 / 2, 3 p 3 / 2 and 3 p 1 / 2 single-particle orbits. The calculated negative parity low-states energy spectra agree quite well with the experimental data. The B (E 2) values have been also calculated and compared with the experimental data. The calculated energy levels and B (E 2) are in good agreement with experimental data than that in the previous study for 195Pt isotope. Furthermore, the energy levels, electric quadrupole transition probabilities and the potential energy surface for even-even platinum isotopes (as core for even-odd nuclei) have been calculated within framework of the Interacting Boson Model (IBM-1). The predicted energy levels and B (E 2) transition probabilities results are reasonably consistent with the experimental data. The contour plot of the potential energy surfaces shows all interesting nuclei are deformed and have ?-unstable-like characters.

The confidence interval of allelic odds ratios under the Hardy-Weinberg disequilibrium.  

PubMed

In single nucleotide polymorphism (SNP) data analysis, the allelic odds ratio and its confidence interval (CI) are usually used to evaluate the association between disease and alleles at each SNP. The usual formula for calculating the CI of the allelic odds ratio based on the Hardy-Weinberg equilibrium (HWE) may, however, lead to errors beyond the control assured by the nominal confidence level if HWE is not true. We therefore present a generalized formula for CI that does not assume HWE. CIs calculated by this generalized formula are likely to be wider than those by the usual method if the Hardy-Weinberg disequilibrium (HWD) is toward a relative deficiency of the heterozygotes (fixation index greater than 0), whereas they are likely to be narrower if HWD is toward a relative excess of the heterozygotes (fixation index less than 0). A simulation experiment to examine the influence of the generalization was performed for the case where 2% of SNPs had a fixation index greater than 0. The result revealed that the generalized method slightly decreased the mean number of falsely detected SNPs. PMID:16917678

Exploring the female specific risk to partial and full PTSD following physical assault.  

PubMed

Previous studies have shown that females are at an increased risk of developing posttraumatic stress disorder (PTSD) in response to physical assault compared with males. Our aims were to (a) test if this gender-specific risk generalised to subclinical levels of PTSD, (b) observe how this relationship was affected by including possible confounding factors, and (c) estimate how this trauma contributed to the overall prevalence of PTSD in females. Data came from an Australian birth cohort study (n = 2,547) based in Brisbane, Australia that commenced in 1981. Using ordinal logistic regression adjusted for a wide range of confounding factors, including polyvictimisation and internalising and externalising symptoms, we found females were at a significantly greater risk compared to males of developing either partial or full PTSD, odds ratio (OR) = 7.68; 95% confidence interval (CI) = [2.94, 20.08], as well as full PTSD only, OR = 9.23; 95% CI = [2.77, 30.79], following the experience of assaultive violence (p value for test of interaction = .004). In addition to the high prevalence of sexual assault (12.9%), attributable risk analysis suggested that due to the strong risk of PTSD in females exposed to physical assault, physical assault is possibly a contributor to the overall female increased prevalence of PTSD.

The German Physical Society in the Third Reich: Local Conservatism between Co-optation and Autonomy.  

NASA Astrophysics Data System (ADS)

During the National Socialism regime the German Physical Society (GPS), like many other German professional organizations, faced difficult choices along the spectrum of co-optation into the Nazi power structure and autonomy from the regime. This paper examines several examples of the Society's actions which shown an seeking to maintain traditional disciplinary standards while at the same time selectively cooperating with some of the regime's expectations. The successful riposte to ardent Nazi Johannes Stark's effort to become GPS chair in 1933 showed that the GPS was able to assert its traditional disciplinary authority structure even in the face of efforts to subsume the Society under the leadership principle favored by the Nazis. The Society's later election of industrial physicist Carl Ramsauer showed the GPS emphsizing the strategic (also military) importance of physics--and also willing to accommodate the regime's demand for the exclusion of non-Aryans. Finally, the choices behind the GPS's awarding of its presitigious Max Planck Medal in the late 1930's and early 40's show that both achievement in physics and political considerations--favoring scientists sympathetic to the regime, avoiding those antagonistic to it--were taken into account. Taken together, these examples demonstrate a kind of ``local conservativism'' that was at some times at odds with Nazi ideology but which nevertheless avoided open confrontation and indeed selectively cooperated with the regime's agenda.

LIMS data - Inferred stratospheric distribution of NOx and HOx trace constituents and the calculated odd nitrogen budget  

NASA Technical Reports Server (NTRS)

LIMS, SAMS, SBUV and in-situ data have been used to infer species not measured but which are of photochemical interest, e.g., O(3P), O(1D), NO, N2O5, OH, HO2, ClO and HCl. (LIMS = limb infrared monitor of the stratosphere; SAMS = stratospheric and mesospheric sounder; and SBUV = solar backscattered ultraviolet instrument.) Production and loss of odd nitrogen have been calculated and estimates have been made of the odd nitrogen transport due to adiabatically driven circulation derived from LIMS data. Data used from LIMS include O3, NO2, HNO3, H2O and T. CH4 and N2O were taken from SAMS and the UV solar flux from the SBUV instrument. Species were inferred for periods in October, December, March and May. Results for December are discussed. Results indicate: (1) maximum stratospheric odd nitrogen levels of 25 ppbv; (2) evidence of odd nitrogen transport from the mesosphere appearing at 25 km in the wintertime polar latitudes; (3) the polar night build-up of high levels of N2O5 beginning after the autumnal equinox; and (4) the possibility of large downward fluxes of odd nitrogen into the troposphere during the winter at latitudes poleward of 60 degrees.

Odd and even partial waves of ??- and ???- in ?- p ?? (?)?- p at 191 GeV / c  

NASA Astrophysics Data System (ADS)

Exclusive production of ??- and ???- has been studied with a 191 GeV / c?- beam impinging on a hydrogen target at COMPASS (CERN). Partial-wave analyses reveal different odd/even angular momentum (L) characteristics in the inspected invariant mass range up to 3 GeV /c2. A striking similarity between the two systems is observed for the L = 2 , 4 , 6 intensities (scaled by kinematical factors) and the relative phases. The known resonances a2 (1320) and a4 (2040) are in line with this similarity. In contrast, a strong enhancement of ???- over ??- is found for the L = 1 , 3 , 5 waves, which carry non- q q bar quantum numbers. The L = 1 intensity peaks at 1.7 GeV /c2 in ???- and at 1.4 GeV /c2 in ??-, the corresponding phase motions with respect to L = 2 are different.

Hairy black holes: Stability under odd-parity perturbations and existence of slowly rotating solutions  

NASA Astrophysics Data System (ADS)

We show that, independently of the scalar field potential and of specific asymptotic properties of the spacetime (asymptotically flat, de Sitter or anti-de Sitter), any static, spherically symmetric or planar, black hole solution of the Einstein theory minimally coupled to a real scalar field with a general potential is mode stable under linear odd-parity perturbations. To this end, we generalize the Regge-Wheeler equation for a generic self-interacting scalar field, and show that the potential of the relevant Schrödinger operator can be mapped, by the so-called S-deformation, to a semipositively defined potential. With these results at hand we study the existence of slowly rotating configurations. The frame dragging effect is compared with the corresponding effect in the case of a Kerr black hole.

Hospitals with higher nurse staffing had lower odds of readmissions penalties than hospitals with lower staffing.  

PubMed

The Affordable Care Act's Hospital Readmissions Reduction Program (HRRP) penalizes hospitals based on excess readmission rates among Medicare beneficiaries. The aim of the program is to reduce readmissions while aligning hospitals' financial incentives with payers' and patients' quality goals. Many evidence-based interventions that reduce readmissions, such as discharge preparation, care coordination, and patient education, are grounded in the fundamentals of basic nursing care. Yet inadequate staffing can hinder nurses' efforts to carry out these processes of care. We estimated the effect that nurse staffing had on the likelihood that a hospital was penalized under the HRRP. Hospitals with higher nurse staffing had 25 percent lower odds of being penalized compared to otherwise similar hospitals with lower staffing. Investment in nursing is a potential system-level intervention to reduce readmissions that policy makers and hospital administrators should consider in the new regulatory environment as they examine the quality of care delivered to US hospital patients.

Limiting P-odd interactions of cosmic fields with electrons, protons, and neutrons.  

PubMed

We propose methods for extracting limits on the strength of P-odd interactions of pseudoscalar and pseudovector cosmic fields with electrons, protons, and neutrons, by exploiting the static and dynamic parity-nonconserving amplitudes and electric dipole moments they induce in atoms. Candidates for such fields are dark matter (including axions) and dark energy, as well as several more exotic sources described by Lorentz-violating standard model extensions. Atomic calculations are performed for H, Li, Na, K, Rb, Cs, Ba(+), Tl, Dy, Fr, and Ra(+). From these calculations and existing measurements in Dy, Cs, and Tl, we constrain the interaction strengths of the parity-violating static pseudovector cosmic field to be 7 × 10(-15) GeV with an electron, and 3 × 10(-8) GeV with a proton.

Identification of 181Hg and shape coexistence in odd-A Hg isotopes  

NASA Astrophysics Data System (ADS)

In-beam ?-ray transitions in 181Hg, the lightest odd-A Hg isotope known thus far, have been identified from fragment mass-? and ?-? coincidence measurements. Five prolate deformed rotational bands were placed in the level scheme. A decoupled band built on the strongly prolate deformed 1/2-[521] ground state was observed up to 29/2-. A 5/2-[512] configuration is suggested for a pair of strongly coupled bands displaying no signature splitting. The other two bands are also signature partner bands. They are populated with the largest intensity and exhibit splitting. They have been associated with the mixed neutron i13/2 orbitals and are proposed to decay to an i13/2 isomeric state associated with an oblate state.

On strontium isotopic anomalies and odd-A p-process abundances. [in solar system  

NASA Technical Reports Server (NTRS)

Several aspects of the nucleosynthesis of Sr isotopes are considered in an attempt to shed light on the problem of the Sr isotopic anomalies discovered in an inclusion of the Allende meteorite. Decomposition of the Sr isotopes into average r-, s-, and p-process nucleosynthetic classes is performed. It is suggested that the Allende inclusion most likely has an excess of s-process Sr and that the initial Sr-87/Sr-86 isotopic ratio is probably slightly more primitive than basaltic achondrites. The results also show that Sn-115 is mostly due to the r-process and that odd-A yields are very small. It is concluded that if the Sr anomaly in the inclusion is an average s enhancement, it argues somewhat in favor of a model of gas/dust fractionation of s and r isotopes during accumulation of the inclusion parent in the protosolar cloud.

We consider relativistic non-Abelian superfluids, where the expectation value of the global symmetry currents relate space and internal indices, thus creating a "locked" phase. Locking a superfluid with SU(2) internal symmetry in 2+1 dimensions breaks parity spontaneously, and introduces parity-odd terms in the constitutive relations. We show that there are qualitatively different extensions of the rest frame locking to non-zero velocities. We construct the resulting superfluid hydrodynamics up to the first derivative order. Using an expansion close to the critical point, we estimate the ratio of the Hall viscosity and the angular momentum density. Our general hydrodynamic results are compatible with the holographic p-wave calculations in arXiv:1311.4882.

Formation of Collisionless High-{beta} Plasmas by Odd-Parity Rotating Magnetic Fields  

SciTech Connect

Odd-parity rotating magnetic fields (RMF{sub o}) applied to mirror-configuration plasmas have produced average electron energies exceeding 200 eV at line-averaged electron densities of {approx}10{sup 12} cm{sup -3}. These plasmas, sustained for over 10{sup 3}{tau}{sub Alfven}, have low Coulomb collisionality, v{sub c}*{identical_to}L/{lambda}{sub C}{approx}10{sup -3}, where {lambda}{sub C} is the Coulomb scattering mean free path and L is the plasma's characteristic half length. Divertors allow reduction of the electron-neutral collision frequency to values where the RMF{sub o} coupling indicates full penetration of the RMF{sub o} to the major axis.

Odd-skipped related 2 regulates genes related to proliferation and development  

SciTech Connect

Cell proliferation is a biological process in which chromosomes replicate in one cell and equally divide into two daughter cells. Our previous findings suggested that Odd-skipped related 2 (Osr2) plays an important role in cellular quiescence and proliferation under epigenetic regulation. However, the mechanism used by Osr2 to establish and maintain proliferation is unknown. To examine the functional role of Osr2 in cell proliferation, we analyzed its downstream target genes using microarray analysis following adenovirus-induced overexpression of Osr2 as well as knockdown with Osr2 siRNA, which showed that Osr2 regulates a multitude of genes involved in proliferation and the cell cycle, as well as development. Additional proliferation assays also indicated that Osr2 likely functions to elicit cell proliferation. Together, these results suggest that Osr2 plays important roles in proliferation and development.

Odd-skipped related 2 is epigenetically regulated in cellular quiescence  

SciTech Connect

Cellular behavior and development are extensively altered during the transition from cell cycle into quiescence, though the mechanism involved in establishing and maintaining quiescence is largely unknown. We found that Odd-skipped related 2 (Osr2) was up-regulated during cellular quiescence by serum starvation as well as culturing to confluence. To investigate the regulatory mechanism of Osr2 under these conditions, we characterized the mouse Osr2 promoter. CpG islands in the flanking region of the transcription start site were predominantly methylated in exponentially growing cells, resulting in silencing of Osr2 expression. In addition, CpG demethylation in quiescence caused activation of Osr2 expression, while acetylation of the H3 and H4 histones during quiescence also led to an increase in Osr2 expression. These results suggest that epigenetically regulated Osr2 plays an important role in cellular quiescence and proliferation.

Odd-parity topological superconductor with nematic order: Application to CuxBi2Se3  

NASA Astrophysics Data System (ADS)

CuxBi2Se3 was recently proposed as a promising candidate for time-reversal-invariant topological superconductors. In this work, we argue that the unusual anisotropy of the Knight shift observed by Zheng and co-workers (unpublished), taken together with specific heat measurements, provides strong support for an unconventional odd-parity pairing in the two-dimensional Eu representation of the D3d crystal point group, which spontaneously breaks the threefold rotational symmetry of the crystal, leading to a subsidiary nematic order. We predict that the spin-orbit interaction associated with hexagonal warping plays a crucial role in pinning the two-component order parameter and makes the superconducting state generically fully gapped, leading to a topological superconductor. Experimental signatures of the Eu pairing related to the nematic order are discussed.

Hospitals With Higher Nurse Staffing Had Lower Odds Of Readmissions Penalties Than Hospitals With Lower Staffing  

PubMed Central

The Affordable Care Act’s Hospital Readmissions Reduction Program (HRRP) penalizes hospitals based on excess readmission rates among Medicare beneficiaries. The aim of the program is to reduce readmissions while aligning hospitals’ financial incentives with payers’ and patients’ quality goals. Many evidence-based interventions that reduce readmissions, such as discharge preparation, care coordination, and patient education, are grounded in the fundamentals of basic nursing care. Yet inadequate staffing can hinder nurses’ efforts to carry out these processes of care. We estimated the effect that nurse staffing had on the likelihood that a hospital was penalized under the HRRP. Hospitals with higher nurse staffing had 25 percent lower odds of being penalized compared to otherwise similar hospitals with lower staffing. Investment in nursing is a potential system-level intervention to reduce readmissions that policy makers and hospital administrators should consider in the new regulatory environment as they examine the quality of care delivered to US hospital patients.

The analytic torsion of a cone over an odd dimensional manifold  

NASA Astrophysics Data System (ADS)

We study the analytic torsion of a cone over an orientable odd dimensional compact connected Riemannian manifold W. We prove that the logarithm of the analytic torsion of the cone decomposes as the sum of the logarithm of the root of the analytic torsion of the boundary of the cone, plus a topological term, plus a further term that is a rational linear combination of local Riemannian invariants of the boundary. We show that this last term coincides with the anomaly boundary term appearing in the Cheeger Müller theorem [3,2] for a manifold with boundary, according to Brüning and Ma (2006) [5]. We also prove Poincaré duality for the analytic torsion of a cone.

Even-odd effect in multifragmentation products: the footprints of evaporation  

E-print Network

The analysis of experimental production cross-sections of intermediate-mass fragments (IMF) of several nuclear reactions at relativistic energy, measured at the FRS, GSI Darmstadt, revealed a very strong and complex even-odd staggering. The origin of this effect is related to the condensation process of hot nuclei while cooling down by evaporation. The characteristics of the staggering correlate strongly with the lowest particle separation energy of the final experimentally observed nuclei, but not with the binding energy. The study confirms the important role of the de-excitation process in multifragmentation reactions, and indicates that sequential decay strongly influences the yields of IMF, which are often used to extract information on the nature of nuclear reactions at high energies.

Maxwell-Chern-Simons vortices in a CPT-odd Lorentz-violating Higgs electrodynamics  

NASA Astrophysics Data System (ADS)

We have studied BPS vortices in a CPT-odd and Lorentz-violating Maxwell-Chern-Simons-Higgs (MCSH) electrodynamics attained from the dimensional reduction of the Carroll-Field-Jackiw-Higgs model. The Lorentz-violating parameter induces a pronounced behavior at origin (for the magnetic/electric fields and energy density) which is absent in the MCSH vortices. For some combination of the Lorentz-violating coefficients there always exist a sufficiently large winding number $n_{0}$ such that for all $% |n|\\geq |n_{0}|$ the magnetic field flips its signal, yielding two well defined regions with opposite magnetic flux. However, the total magnetic flux remains quantized and proportional to the winding number.

Optimal odd-periodic complementary sequences for diffuse wireless optical communications  

NASA Astrophysics Data System (ADS)

Indoor wireless optical communication (WOC) systems become promising because of their distinct advantages over their radio frequency counterparts. We address the optimal odd-periodic complementary sequences (OPCSs) for estimating a channel impulse response in WOC systems. Based on the Cramer-Rao bound, a criterion for design the optimal OPCSs is introduced. Optimum OPCSs are obtained and tabulated by computer search for different channel responses and OPCS length. Moreover, the sequence detection performance measured by bit error ratio (BER) for OPCSs-based channel estimation is also investigated. Simulation results show that the sequence detection performance can be significantly improved by using the optimal OPCS pairs. Moreover, the longer OPCS is, the better a BER performance can be obtained when the channel order is held fixed.

Bose-Fermi symmetry in the odd-even gold isotopes  

NASA Astrophysics Data System (ADS)

In this work the results of an in-beam experiment on 195Au are presented, yielding new spins, multipole mixing ratios, and new low-lying states essential for the understanding of this nucleus. The positive-parity states from this work together with compiled data from the available literature for 185-199Au are compared to Interacting Boson Fermion Model calculations employing the Spin(6) Bose-Fermi symmetry. The evolution of the parameters for the ? splitting and the J splitting reveals a smooth behavior. Thereby, a common description based on the Bose-Fermi symmetry is found for 189-199Au. Furthermore, the calculated E2 transition strengths are compared to experimental values with fixed effective boson and fermion charges for all odd-even gold isotopes, emphasizing that the Spin(6) Bose-Fermi symmetry is valid for the gold isotopes.

What are the Odds? The Neural Correlates of Active Choice during Gambling  

PubMed Central

Gambling is a widespread recreational activity and requires pitting the values of potential wins and losses against their probability of occurrence. Neuropsychological research showed that betting behavior on laboratory gambling tasks is highly sensitive to focal lesions to the ventromedial prefrontal cortex (vmPFC) and insula. In the current study, we assessed the neural basis of betting choices in healthy participants, using functional magnetic resonance imaging of the Roulette Betting Task. In half of the trials, participants actively chose their bets; in the other half, the computer dictated the bet size. Our results highlight the impact of volitional choice upon gambling-related brain activity: Neural activity in a distributed network – including key structures of the reward circuitry (midbrain, striatum) – was higher during active compared to computer-dictated bet selection. In line with neuropsychological data, the anterior insula and vmPFC were more activated during self-directed bet selection, and responses in these areas were differentially modulated by the odds of winning in the two choice conditions. In addition, responses in the vmPFC and ventral striatum were modulated by the bet size. Convergent with electrophysiological research in macaques, our results further implicate the inferior parietal cortex (IPC) in the processing of the likelihood of potential outcomes: Neural responses in the IPC bilaterally reflected the probability of winning during bet selection. Moreover, the IPC was particularly sensitive to the odds of winning in the active-choice condition, when the processing of this information was required to guide bet selection. Our results indicate an important role of the IPC in human decision-making under risk and help to integrate neuropsychological data of risk-taking following vmPFC and insula damage with models of choice derived from human neuroimaging and monkey electrophysiology.

Exposure to childhood traumas ups the odds of giving birth to daughters.  

PubMed

This study examined the likelihood of giving birth to a daughter as a function of women's exposure to four categories of stressors: childhood trauma, adult trauma, chronic stressors, and recent (adverse) life events. Hypothesis 1 stated that exposure to recent life events (near conception) and to childhood traumas would increase women's chances of having a girl baby. Hypothesis 2 stated that the relationship between stress and gender outcome is mediated by persistent posttraumatic stress disorder (PTSD) symptoms. The final sample was comprised of 225 women. The design was prospective observational. At first contact, women were retained if they were <27 weeks pregnant and met initial inclusion criteria. In interview 2, at 27-30 weeks, women were excluded for positive diagnoses of anxiety disorders besides PTSD with or without depression (Structured Clinical Interview for DSM-IV Disorders). In interview 3 (30-34 weeks), reports on stress categories (Social Stress Indicator Questionnaire) and PTSD symptoms (Post-Traumatic Checklist) were obtained. Infant gender was obtained from medical records. The relationship between stress categories and the distribution of girl/boy infants was examined with Chi Squares and logistic regression analyses. Mediation was tested with the macro PROCESS (Hayes 2012). Childhood trauma was the only stress category that increased the odds of having a girl, with an odds ratio of >3.0 for women who had been exposed to more than two such events. PTSD symptoms (partially) mediated the relationship between childhood trauma and infant gender. Findings suggest that women's exposure to childhood trauma contributes to the determination of the sex ratio at birth and that PTSD symptoms are part of the cause. PMID:24221408

Interpretation of the odd-even behavior for the emergence of ferroelectricity and antiferroelectricity in bent-core mesogens  

NASA Astrophysics Data System (ADS)

Simple theoretical interpretation has been made on the previously reported odd-even behavior of the emergence of ferroelectricity and antiferroelectricity in homologous series of bent-core mesogens with the same chiral end chains (S,S) ; compounds with even and odd carbon numbers (including oxygen) exhibit ferroelectric and antiferroelectric B2 phases, respectively. The odd-even behavior was confirmed in newly synthesized racemic compounds with chiral end chains of R and S forms (R,S) together with (R,R) and (S,S) forms. According to our theoretical interpretation, ferroelectricity should be more stable in (R,S) compounds than in (S,S) compounds. Actually, the transition temperature from the isotropic phase to the Sm-CP phase was higher and the temperature range of the B2 phase was broader in the (R,S) compound than in the (S,S) compound.

Organic solute changes with acidification in Lake Skjervatjern as shown by [sup 1]H-NMR spectroscopy  

SciTech Connect

[sup 1]H-NMR spectroscopy has been found to be a useful tool to establish possible real differences and trends between all natural organic solute fractions (fulvic acids, humic acids, and XAD-4 acids) after acid-rain additions to the Lake Skjervatjern watershed. The proton NMR technique used in this study determined the spectral distribution of nonexchangeable protons among four peaks (aliphatic protons; aliphatic protons on carbon [alpha] or attached to electronegative groups; protons on carbons attached to O or N heteroatoms; and aromatic protons). Differences of 10% or more in the respective peak areas were considered to represent a real difference. After one year of acidification, fulvic acids decreased 13% (relative) in Peak 3 protons on carbon attached to N and O heteroatoms and exhibited a decrease in aromatic protons between 27% and 31%. Humic acids also exhibited an 11% relative decrease in aromatic protons as a result of acidification. After one year of acidification, real changes were shown in three of the four proton assignments in XAD-4 acids. Peak 1 aliphatic protons increased by 14% (relative), Peak 3 protons on carbons attached to O and N heteroatoms decreased by 13% (relative), and aromatic protons (Peak 4) decreased by 35% (relative). Upon acidification, there was a trend in all solutes for aromatic protons to decrease and aliphatic protons to increase. The natural variation in organic solutes as shown in the Control Side B of the lake from 1990 to 1991 is perhaps a small limitation to the same data interpretations of acid rain changes at the Lake Skjervatjern site, but the proton NMR technique shows great promise as an independent scientific tool to detect and support other chemical techniques in establishing organic solute changes with different treatments (i.e., additions of acid rain). 8 refs., 5 figs., 1 tab.

The low-lying dipole strength distributions of the odd-mass isotopes {sup 139}La and {sup 141}Pr were studied in nuclear resonance fluorescence experiments using bremsstrahlung beams. Excited states were observed at excitation energies up to 4 MeV. Spectroscopic information was obtained on excitation energies, decay widths, decay branching ratios, and transition probabilities. The states belonging to the [[2{sup +}(multiply-in-circle sign)3{sup -}](multiply-in-circle sign)particle/hole] coupling were a special focus, and the results are compared with other stable odd-mass nuclei at or near the N=82 shell closure.

Localization of a marine source of odd chain-length fatty acids. I. The amphipod Pontoporeia femorata (Kröyer).  

PubMed

The amphipod Pontoporeia femorata (Kröyer) contains approximately equal amounts of odd chain length and even chain length fatty acids. Mature males of this species are released into the waters of Jeddore Harbour during winter months as the result of a regular reproductive cycle and become food for smelt Osmerus mordax moving into the harbor in preparation for spring spawning runs, thus accounting for the previously reported unusual fatty acid composition of these smelt. The exceptionally high levels of odd chain length fatty acids in P. femorata occur at all stages of maturity in both sexes of the animal and are found in P. femorata in other locations. PMID:1011943

Emotional and rational product appeals in televised food advertisements for children: analysis of commercials shown on US broadcast networks.  

PubMed

The aggressive advertising and marketing of high caloric food products to children is implicated as a potential causative factor in the childhood obesity epidemic. This study analyzed 147 commercials appearing during children's programming on U.S. broadcast networks for a wide range of potential emotional and rational advertising appeals. The most prominent emotional appeals were fun/happiness and play followed by fantasy/ imagination, social enhancement/peer acceptance, and coolness/hipness. Many of the products used the term ;super-charged' or a similar adjective to describe the powerful taste or other physical properties of the product. More than one-third of all the commercials used a fruit appeal or association. Statements or depictions that a product was healthy or nutritious were quite rare among the commercials. This seems to imply that health and nutrition claims are understood by food marketers to not be salient concerns among children and as such are not a selling point to children. Commercials for high sugar cereal products and fast food restaurants differed in several respects. This study can serve to guide child health care professionals and other child advocates in designing measures that counter food advertising messages directed at children. PMID:18039734

Transtibial ACL Femoral Tunnel Preparation Increases Odds of Repeat Ipsilateral Knee Surgery  

PubMed Central

Background: Recent efforts to improve the results of anterior cruciate ligament (ACL) reconstruction have focused on placing the femoral tunnel anatomically. Medial portal femoral tunnel techniques facilitate drilling of femoral tunnels that are more anatomic than those made with transtibial techniques. Few studies have compared the clinical outcomes of these two femoral tunnel techniques. We hypothesized that the transtibial technique is associated with decreased Knee injury and Osteoarthritis Outcome Scores (KOOS) and an increased risk of repeat surgery in the ipsilateral knee when compared with the anteromedial portal technique. Methods: Four hundred and thirty-six patients who had undergone primary isolated autograft ACL reconstruction with a transtibial (229 patients) or anteromedial portal (207 patients) technique in 2002 or 2003 were identified in a prospective multicenter cohort. A multiple linear regression model was used to determine whether surgical technique (transtibial or anteromedial portal) was a significant predictor of KOOS at six years postoperatively, after controlling for preoperative KOOS, patient age, sex, activity level, body mass index (BMI), smoking status, graft type, and the presence of meniscal and chondral pathology at the time of reconstruction. A multiple logistic regression model was used to determine whether surgical technique was a significant predictor of repeat ipsilateral knee surgery, after controlling for patient age and activity level, graft type, and meniscal pathology at the time of reconstruction. Results: Postoperative KOOS were available for 387 patients (88.8%). Femoral tunnel drilling technique was not a predictor of the KOOS Quality of Life subscore (p = 0.72) or KOOS Function, Sports and Recreational Activities subscore (p = 0.36) at the six-year follow-up evaluation. Data regarding the prevalence of repeat surgery were available for 380 patients. Femoral tunnel technique was a significant predictor of subsequent ipsilateral knee surgery (odds ratio [OR] = 2.49, 95% confidence interval [CI] = 1.30 to 4.78, p = 0.006). Conclusions: Patients who underwent ACL reconstruction with a transtibial technique had significantly higher odds of undergoing repeat ipsilateral knee surgery relative to those who underwent reconstruction with an anteromedial portal technique. Level of Evidence: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence. PMID:24257662

First identification of resident and circulating fibrocytes in Dupuytren's disease shown to be inhibited by serum amyloid P and Xiapex.  

PubMed

Dupuytren's disease (DD) is a common progressive fibroproliferative disorder causing permanent digital contracture. Proliferative myofibroblasts are thought to be the cells responsible for DD initiation and recurrence, although their source remains unknown. DD tissue has also been shown to harbor mesenchymal and hematopoietic stem cells. Fibrocytes are circulating cells that show characteristics of fibroblasts and they express surface markers for both hematopoietic and mesenchymal stromal cells. Fibrocytes differentiate from peripheral CD14+ mononuclear cells, which can be inhibited by serum amyloid P (SAP). In this study we have demonstrated the presence of fibrocytes in DD blood and tissue, moreover we have evaluated the effects of SAP and Xiapex (Collagenase Clostridium histolyticum) on fibrocytes derived from DD. H&E staining showed typical Spindle shaped morphology of fibrocytes. FACS analysis based on a unique combination of 3 markers, revealed the increased presence of fibrocytes in blood and tissue of DD patients. Additionally, immunohistology of DD nodule and cord tissue showed the presence of collagen 1+/CD34+ cells. No difference in plasma SAP levels was observed between DD and control. Higher concentrations of SAP significantly inhibited fibrocytes differentiated from DD derived monocytes compared to control. DD fascia derived fibrocytes showed resistance to growth inhibition by SAP, particularly nodule derived fibrocytes showed robust growth even at higher SAP concentrations compared to control. DD derived fibrocytes were positive for typical fibrocyte dual markers, i.e. Collagen 1/LSP-1 and collagen 1/CD34. Xiapex was more effective in inhibiting the growth of nodule derived cells compared to commercially available collagenase A. Our results show for the first time the increased presence of fibrocytes in DD patient's blood and disease tissue compared to control tissue. Additionally, we evaluate the response of these fibrocytes to SAP and Xiapex therapy. PMID:24933153

Fast-track attribution assessments based on pre-computed estimates of changes in the odds of warm extremes  

NASA Astrophysics Data System (ADS)

Regional warming due to anthropogenic influence on the climate is expected to increase the frequency of very warm years and seasons. The growing research area of extreme event attribution has provided pertinent scientific evidence for a number of such warm events for which the forced climate response rises above internal climatic variability. Although the demand for attribution assessments is higher shortly after an event occurs, most scientific studies become available several months later. A formal attribution methodology is employed here to pre-compute the changing odds of very warm years and seasons in regions across the world. Events are defined based on the exceedence of temperature thresholds and their changing odds are measured over a range of pre-specified thresholds, which means assessments can be made as soon as a new event happens. Optimal fingerprinting provides observationally constrained estimates of the global temperature response to external forcings from which regional information is extracted. This information is combined with estimates of internal variability to construct temperature distributions with and without the effect of anthropogenic influence. The likelihood of an event is computed for each distribution and the change in the odds estimated. Analyses are conducted with seven climate models to explore the model dependency of the results. Apart from colder regions and seasons, characterised by greater internal climate variability, the odds of warm events are found to have significantly increased and temperatures above the threshold of 1-in-10 year events during 1961-1990 have become at least twice as likely to occur.

Electroweak Physics at the ILC  

E-print Network

Some aspects of electroweak physics at the International Linear Collider (ILC) are reviewed. The importance of precision measurements in the Higgs sector and in top-quark physics is emphasized, and the physics potential of the GigaZ option of the ILC is discussed. It is shown in particular that even in a scenario where the states of new physics are so heavy that they would be outside of the reach of the LHC and the first phase of the ILC, the GigaZ precision on the effective weak mixing angle may nevertheless allow the detection of quantum effects of new physics.

Teachers' approaches to teaching physics  

NASA Astrophysics Data System (ADS)

Benjamin Franklin said, "Tell me, and I forget. Teach me, and I remember. Involve me, and I learn." He would not be surprised to learn that research in physics pedagogy has consistently shown that the traditional lecture is the least effective teaching method for teaching physics. We asked high school physics teachers which teaching activities they used in their classrooms. While almost all teachers still lecture sometimes, two-thirds use something other than lecture most of the time. The five most often-used activities are shown in the table below. In the January issue, we will look at the 2013 Nationwide Survey of High School Physics teachers. Susan White is Research Manager in the Statistical Research Center at the American Institute of Physics; she directs the Nationwide Survey of High School Physics Teachers.

Mycobacterium tuberculosis is the causative agent of tuberculosis in the southern ecological zones of Cameroon, as shown by genetic analysis  

PubMed Central

Background Tuberculosis (TB) is a major cause of mortality and suffering worldwide, with over 95% of TB deaths occurring in low- and middle-income countries. In recent years, molecular typing methods have been widely used in epidemiological studies to aid the control of TB, but this usage has not been the case with many African countries, including Cameroon. The aims of the present investigation were to identify and evaluate the diversity of the Mycobacterium tuberculosis complex (MTBC) isolates circulating in two ecological zones of Cameroon, seven years after the last studies in the West Region, and after the re-organization of the National TB Control Program (NTBCP). These were expected to shed light also on the transmission of TB in the country. The study was conducted from February to July 2009. During this period, 169 patients with symptomatic disease and with sputum cultures that were positive for MTBC were randomly selected for the study from amongst 964 suspected patients in the savannah mosaic zone (West and North West regions) and the tropical rainforest zone (Central region). After culture and diagnosis, DNA was extracted from each of the MTBC isolates and transported to the BecA-ILRI Hub in Nairobi, Kenya for molecular analysis. Methods Genetic characterization was done by mycobacterial interspersed repetitive unit–variable number tandem repeat typing (MIRU-VNTR) and Spoligotyping. Results Molecular analysis showed that all TB cases reported in this study were caused by infections with Mycobacterium tuberculosis (98.8%) and Mycobacterium africanum (M. africanum) (1.2%) respectively. We did not detect any M. bovis. Comparative analyses using spoligotyping revealed that the majority of isolates belong to major clades of M. tuberculosis: Haarlem (7.6%), Latin American-Mediterranean (34.4%) and T clade (26.7%); the remaining isolates (31.3%) where distributed among the minor clades. The predominant group of isolates (34.4%) corresponded to spoligotype 61, previously described as the “Cameroon family. Further analysis based on MIRU-VNTR profiles had greater resolving power than spoligotyping and defined additional genotypes in the same spoligotype cluster. Conclusion The molecular characterization of MTBC strains from humans in two ecological regions of Cameroon has shown that M. tuberculosis sensu stricto is the predominant agent of TB cases in the zones. Three decades ago, TB was reported to be caused by M. africanum in 56.0% of cases. The present findings are consistent with a major shift in the prevalence of M. tuberculosis in Cameroon.

Quasiclassical Treatment and Odd-Parity/Triplet Correspondence in Topological Superconductors  

NASA Astrophysics Data System (ADS)

We construct a quasiclassical framework for topological superconductors with a strong spin–orbit coupling such as CuxBi2Se3. In a manner of the quasiclassical treatment, by decomposing the slowly varying component from a total quasiparticle wave function, the original massive Dirac Bogoliubov–de Gennes (BdG) Hamiltonian derived from a tight-binding model represented by an 8 × 8 matrix is reduced to a 4 × 4 matrix. The resultant equations are equivalent to Andreev-type equations of singlet or triplet superconductors, in which the apparent spin–orbit coupling vanishes. Using this formalism, we find that the odd-parity superconductivity in topological superconductors turns to the spin-triplet one. Moreover, in terms of quasiclassical treatment, we show that the topologically-protected zero-energy states in topological superconductors have correspond to the Andreev bound states established in a long history of studies of unconventional superconductors. This clearly indicates that low-energy nontrivial superconducting properties in the topological superconductors can be analyzed using established theoretical descriptions of the spin-triplet superconductors.

Spatial properties of odd and even low order harmonics generated in gas  

PubMed Central

High harmonic generation in gases is developing rapidly as a soft X-ray femtosecond light-source for applications. This requires control over all the harmonics characteristics and in particular, spatial properties have to be kept very good. In previous literature, measurements have always included several harmonics contrary to applications, especially spectroscopic applications, which usually require a single harmonic. To fill this gap, we present here for the first time a detailed study of completely isolated harmonics. The contribution of the surrounding harmonics has been totally suppressed using interferential filtering which is available for low harmonic orders. In addition, this allows to clearly identify behaviors of standard odd orders from even orders obtained by frequency-mixing of a fundamental laser and of its second harmonic. Comparisons of the spatial intensity profiles, of the spatial coherence and of the wavefront aberration level of 5? at 160?nm and 6? at 135?nm have then been performed. We have established that the fundamental laser beam aberrations can cause the appearance of a non-homogenous donut-shape in the 6? spatial intensity distribution. This undesirable effect can be easily controlled. We finally conclude that the spatial quality of an even harmonic can be as excellent as in standard generation. PMID:25585715

A mid-latitude balloon-borne observation of total odd nitrogen  

NASA Technical Reports Server (NTRS)

A balloon-borne instrument to measure total odd nitrogen NO(y) has been developed. A converter which enables catalytic conversion of NO(y) into nitric oxide on a heated gold surface is combined with a chemiluminescence detector. The conversion efficiency for NO2 was measured to be close to 100 percent at pressures between 60 and 7 mb. The major source of errors in the balloon-borne measurements are the uncertainties in the estimates of the sample flow rate and the zero level of the instrument. The NO(y) concentration was measured at altitudes between 12 and 28 km with a precision of about 25 percent on a balloon experiment conducted at latitude 44 deg N in June 1989. The NO(y) concentration has been measured to be 1.5 + or - 0.4, 3 + or - 0.7, 10 + or - 3, and 14 + or - 4 ppbv at altitudes of 17, 20, 25, and 28 km, respectively.

Predictions on properties of ? decay and spontaneous fission in superheavy odd-Z nuclei  

NASA Astrophysics Data System (ADS)

We systematically investigate the competition between ? decay and spontaneous fission in the region of superheavy odd-Z nuclei up to Z = 121 . The heavier cluster emissions are somewhat of interest for these superheavy nuclei (SHN) as well. In detail, on the basis of the density-dependent cluster model, the deformed ? -core potential is obtained from the double-folding integral. The ? -decay half-lives of involved nuclei are then achieved within the improved two-potential approach. On the other hand, the spontaneous fission half-lives are given by the employed formula related to the fissility parameter and the fission barrier height. It is interesting that the decay characteristic of studied nuclei is discussed with varying of the Z and N numbers to some extent, including the tentative detection on the "island of stability." The present results can be expected to be useful in the future experiment particularly for the unknown elements 119 and 121, namely the identification of synthesized SHN.

A grossly warped nanographene and the consequences of multiple odd-membered-ring defects.  

PubMed

Graphite, the most stable form of elemental carbon, consists of pure carbon sheets stacked upon one another like reams of paper. Individual sheets, known as graphene, prefer planar geometries as a consequence of the hexagonal honeycomb-like arrangements of trigonal carbon atoms that comprise their two-dimensional networks. Defects in the form of non-hexagonal rings in such networks cause distortions away from planarity. Herein we report an extreme example of this phenomenon. A 26-ring C80H30 nanographene that incorporates five seven-membered rings and one five-membered ring embedded in a hexagonal lattice was synthesized by stepwise chemical methods, isolated, purified and fully characterized spectroscopically. Its grossly warped structure was revealed by single-crystal X-ray crystallography. An independent synthetic route to a freely soluble derivative of this new type of 'nanocarbon' is also reported. Experimental data reveal how the properties of such a large graphene subunit are affected by multiple odd-membered-ring defects. PMID:23965674

Obesity and the Odds of Weight Gain following Androgen Deprivation Therapy for Prostate Cancer  

PubMed Central

Background. Increasing body mass index (BMI) is associated with increased risk of mortality; however, quantifying weight gain in men undergoing androgen deprivation therapy (ADT) for prostate cancer (PC) remains unexplored. Methods. Between 1995 and 2001, 206 men were enrolled in a randomized trial evaluating the survival difference of adding 6 months of ADT to radiation therapy (RT). BMI measurements were available in 171 men comprising the study cohort. The primary endpoint was weight gain of ?10?lbs by 6-month followup. Logistic regression analysis was performed to assess whether baseline BMI or treatment received was associated with this endpoint adjusting for known prognostic factors. Results. By the 6-month followup, 12 men gained ?10?lbs, of which 10 (83%) received RT + ADT and, of these, 7 (70%) were obese at randomization. Men treated with RT as compared to RT + ADT were less likely to gain ?10?lbs (adjusted odds ratio (AOR): 0.18 [95% CI: 0.04–0.89]; P = 0.04), whereas this risk increased with increasing BMI (AOR: 1.15 [95% CI: 1.01–1.31]; P = 0.04). Conclusions. Consideration should be given to avoid ADT in obese men with low- or favorable-intermediate risk PC where improved cancer control has not been observed, but shortened life expectancy from weight gain is expected.

Against the odds: foster carers' perceptions of family, commitment and belonging in successful placements.  

PubMed

This study examines carer attributes associated with placement stability for teenagers growing up in long term foster care, focusing on unexpected placement success. We explored experiences and perceptions relating to family, belonging and commitment in a group of foster carers providing a stable placement for a young person who had not been expected to settle. These placements showed positive outcome, despite factors in the child's history that might have predicted otherwise. Seven foster carers were interviewed following a semi-structured guide, which covered their ideas about their relationship with the child in question, about the foster family, and the child's sense of belonging in foster and birth family. Analysis of carers' accounts of placements which had succeeded 'against the odds' revealed four major themes, described under the headings My Child--emotional bonding, the carers' enlarged view of family and their parental regard for the young person; Jam in the Sandwich--working within a 'compromised space' between Local Authority and birth family; Repair and Rebuild--the craft of fostering including managing the foster/birth family boundary; Sticking with It--resilience, tenacity and maintaining hopefulness. The carers' accounts offer pointers towards the ingredients of successful placements and prompt reflection on how these may be supported and promoted. They also highlight tensions inherent in the foster carer task relating to carers' parental functioning for young people in long-term foster care. PMID:22104365

Predicting preference-based utility values using partial proportional odds models  

PubMed Central

Background The majority of analyses on utility data have used ordinary least square (OLS) regressions to explore potential relationships. The aim of this paper is to explore the benefits of response mapping onto health dimension profiles to generate preference-based utility scores using partial proportional odds models (PPOM). Methods Models are estimated using EQ-5D data collected in the Health Survey for England and the predicted utility scores are compared with those obtained using OLS regressions. Explanatory variables include age, acute illness, educational level, general health, deprivation and survey year. The expected EQ-5D scores for the PPOMs are obtained by weighting the predicted probabilities of scoring one, two or three for the five health dimensions by the corresponding preference-weights. Results The EQ-5D scores obtained using the probabilities from the PPOMs characterise the actual distribution of EQ-5D preference-based utility scores more accurately than those obtained from the linear model. The mean absolute and mean squared errors in the individual predicted values are also reduced for the PPOM models. Conclusions The PPOM models characterise the underlying distributions of the EQ-5D data better than models obtained using OLS regressions. Additional research exploring the effect of modelling conditional responses and two part models could potentially improve the results further. PMID:25000846

Unusual luminescent properties of odd- and even-substituted naphthyl-derivatized dioxetanes.  

PubMed

With the advent of enzymatically induced chemiluminescence and improved instrumentation for luminometry, ultrasensitive detection of a wide variety of analytes is now possible using standard immunoassay and DNA probe formats. Model molecular orbital calculations and literature precedent suggest that the singlet efficiencies observed upon decomposition of dioxetanes appended with donor substituted aromatic moieties are dependent on substitution pattern. We have recently discovered, in a series of 3-(2'-spiroadamantane)-4-methoxy-4-acetoxynaphth-2'-yl-1,2-+ ++dioxetanes, that enzymatic generation of a non-conjugated, charge transfer excited state results in luminescence of markedly different properties than that observed from an isomeric, conjugated excited state. An example of the former type, 3-(2'-spiroadamantane)-4-methoxy-4-(7"-acetoxy)naphth-2'-yl- 1,2- dioxetane (1) emitting at 550 nm, not only provides an increase in phi CL, but exhibits a dramatic bathochromic shift of 80-110 nm from the 460 nm emission of the conjugated isomer 3-(2'-spiroadamantane)-4-methoxy-4-(6"-acetoxy)naphth-2'-yl- 1,2-dioxetane (2). These developments, along with the attendant glow-type luminescence kinetics displayed during the enzymatic decomposition of the new 'odd-pattern' dioxetane, allow the design of simple protocols capable of simultaneous or 'multichannel' detection of several analytes.

Odd electron diffraction patterns in silicon nanowires and silicon thin films explained by microtwins and nanotwins  

PubMed Central

Odd electron diffraction patterns (EDPs) have been obtained by transmission electron microscopy (TEM) on silicon nanowires grown via the vapour–liquid–solid method and on silicon thin films deposited by electron beam evaporation. Many explanations have been given in the past, without consensus among the scientific community: size artifacts, twinning artifacts or, more widely accepted, the existence of new hexagonal Si phases. In order to resolve this issue, the microstructures of Si nanowires and Si thin films have been characterized by TEM, high-resolution transmission electron microscopy (HRTEM) and high-resolution scanning transmission electron microscopy. Despite the differences in the geometries and elaboration processes, the EDPs of the materials show great similarities. The different hypotheses reported in the literature have been investigated. It was found that the positions of the diffraction spots in the EDPs could be reproduced by simulating a hexagonal structure with c/a = 12(2/3)1/2, but the intensities in many EDPs remained unexplained. Finally, it was established that all the experimental data, i.e. EDPs and HRTEM images, agree with a classical cubic silicon structure containing two microstructural defects: (i) overlapping ?3 microtwins which induce extra spots by double diffraction, and (ii) nanotwins which induce extra spots as a result of streaking effects. It is concluded that there is no hexagonal phase in the Si nanowires and the Si thin films presented in this work. PMID:22477767

Radiative-lifetime measurements and calculations of odd-parity highly excited levels in Ba i  

SciTech Connect

Natural radiative lifetime measurements have been performed for 70 odd-parity highly excited levels of neutral barium in the energy range from 308 15.512 to 417 59.93 cm{sup -1} by a time-resolved laser-induced fluorescence technique in a laser-produced plasma. The lifetime values measured in this paper are in the range from 11.3 to 901 ns. They are compared with the published lifetimes of four levels. Two of them are in good agreement, whereas for the other two our measurements are slightly longer than the published data. The reasons for the discrepancies are discussed. Comparisons with theoretical results of the Hartree-Fock method with relativistic corrections illustrate the difficulties associated with the use of Cowan's codes for obtaining accurate branching fractions for transitions depopulating highly excited levels along the Rydberg series of heavy neutral elements. This work will be useful to extend the set of oscillator strengths available in Ba i.

A balloon-borne instrument to measure total odd nitrogen (NO{sub y}) has been developed. A converter which enables catalytic conversion of NO{sub y} into nitric oxide on a heated gold surface is combined with a chemiluminescence detector. The conversion efficiency for nitrogen dioxide was measured to be close to 100% at pressures between 60 and 7 mb. The major source of errors in the balloon-borne measurements are the uncertainties in the estimates of the sample flow rate and the zero level of the instrument. The NO{sub y} concentration was measured at altitudes between 12 and 28 km with a precision of about 25% on a balloon experiment conducted at latitude 44{degree}N in June, 1989. The NO{sub y} concentration has been measured to be 1.5{plus minus}0.4, 3{plus minus}0.7, 10{plus minus}3, and 14{plus minus}4 ppbv at altitudes of 17, 20, 25, and 28 km, respectively. This was the first in situ NO{sub y} measurement in the stratosphere above 20 km.

Comparison of the Structure and Expression of Odd-Skipped and Two Related Genes That Encode a New Family of Zinc Finger Proteins in Drosophila  

PubMed Central

The odd-skipped (odd) gene, which was identified on the basis of a pair-rule segmentation phenotype in mutant embryos, is initially expressed in the Drosophila embryo in seven pair-rule stripes, but later exhibits a segment polarity-like pattern for which no phenotypic correlate is apparent. We have molecularly characterized two embryonically expressed odd-cognate genes, sob and bowel (bowl), that encode proteins with highly conserved C(2)H(2) zinc fingers. While the Sob and Bowl proteins each contain five tandem fingers, the Odd protein lacks a fifth (C-terminal) finger and is also less conserved among the four common fingers. Reminiscent of many segmentation gene paralogues, the closely linked odd and sob genes are expressed during embryogenesis in similar striped patterns; in contrast, the less-tightly linked bowl gene is expressed in a distinctly different pattern at the termini of the early embryo. Although our results indicate that odd and sob are more likely than bowl to share overlapping developmental roles, some functional divergence between the Odd and Sob proteins is suggested by the absence of homology outside the zinc fingers, and also by amino acid substitutions in the Odd zinc fingers at positions that appear to be constrained in Sob and Bowl.

Maternal complement C1q and increased odds for psychosis in adult offspring.  

PubMed

The presence of maternal antibodies to food and infectious antigens may confer an increased risk of developing schizophrenia and psychosis in adult offspring. Complement factor C1q is an immune molecule with multiple functions including clearance of antigen-antibody complexes from circulation and mediation of synaptic pruning during fetal brain development. To determine if maternal C1q was associated with offspring schizophrenia and psychosis, we evaluated 55 matched case-control maternal serum pairs from the National Collaborative Perinatal Project. Sample pairs were composed of mothers whose offspring developed psychoses as adults and those whose offspring were free from psychiatric disease. Matching criteria for offspring included birth date, delivery hospital, race, and gender, with further matching based on mother's age. IgG markers of C1q, bovine milk casein, egg ovalbumin, and wheat gluten were measured with enzyme-linked immunosorbent assays. C1q levels were compared to food antigen IgG and to previously generated data for C-reactive protein, adenovirus, herpes simplex viruses, influenza viruses, measles virus, and Toxoplasma gondii. C1q was significantly elevated in case mothers with odds ratios of 2.66-6.31 (conditional logistic regressions, p ? 0.008-0.05). In case mothers only, C1q was significantly correlated with antibodies to both food and infectious antigens: gluten (R(2)=0.26, p ? 0.004), herpes simplex virus type 2 (R(2)=0.21, p ? 0.02), and adenovirus (R(2)=0.25, p ? 0.006). In conclusion, exposure to maternal C1q activity during pregnancy may be a risk factor for the development of schizophrenia and psychosis in offspring. Prenatal measurement of maternal C1q may be an important and convergent screening tool to identify potentially deleterious immune activation from multiple sources. PMID:25195065

Against All Odds: Genocidal Trauma Is Associated with Longer Life-Expectancy of the Survivors  

PubMed Central

Does surviving genocidal experiences, like the Holocaust, lead to shorter life-expectancy? Such an effect is conceivable given that most survivors not only suffered psychosocial trauma but also malnutrition, restriction in hygienic and sanitary facilities, and lack of preventive medical and health services, with potentially damaging effects for later health and life-expectancy. We explored whether genocidal survivors have a higher risk to die younger than comparisons without such background. This is the first population-based retrospective cohort study of the Holocaust, based on the entire population of immigrants from Poland to Israel (N?=?55,220), 4–20 years old when the World War II started (1939), immigrating to Israel either between 1945 and 1950 (Holocaust group) or before 1939 (comparison group; not exposed to the Holocaust). Hazard of death – a long-term outcome of surviving genocidal trauma – was derived from the population-wide official data base of the National Insurance Institute of Israel. Cox regression yielded a significant hazard ratio (HR?=?0.935, CI (95%)?=?0.910–0.960), suggesting that the risk of death was reduced by 6.5 months for Holocaust survivors compared to non-Holocaust comparisons. The lower hazard was most substantial in males who were aged 10–15 (HR?=?0.900, CI (95%)?=?0.842–0.962, i.e., reduced by 10 months) or 16–20 years at the onset of the Holocaust (HR?=?0.820, CI (95%)?=?0.782–0.859, i.e., reduced by18 months). We found that against all odds genocidal survivors were likely to live longer. We suggest two explanations: Differential mortality during the Holocaust and “Posttraumatic Growth” associated with protective factors in Holocaust survivors or in their environment after World War II.

Electron capture strength on odd-A nucleus $\\mathbf{^{59}}$Co in explosive astrophysical environment  

E-print Network

The Gamow-Teller (GT) transitions within massive stars play sumptuous role in the dynamics of core collapse supernovae. GT strength distributions and electron capture rates have been calculated for odd-A nucleus $^{59}$Co within the proton-neutron quasiparticles random phase approximation (pn-QRPA) formalism. The pn-QRPA results are compared with other model calculations and (n, p) reaction experiment carried out at TRIUMF charge-exchange facility. The pn-QRPA calculated a total $B(GT_{+})$ strength of 3.3 for $^{59}$Co to be compared with the shell model value of 2.5 and the 1.9 $\\pm$ 0.1 in the (n, p) charge-exchange reaction. Aufderheide et. al. \\cite{Aufderheide93} extracted total strength equaling 2.4 $\\pm$ 0.3. The placement of GT centroid at 5.6 MeV by the pn-QRPA model is in reasonable agreement with the shell model centroid at 5.1 MeV whereas the measured GT centroid was placed at 4.4 $\\pm$ 0.3 MeV in the (n, p) experiment. Fuller, Fowler and Newman (FFN) \\cite{FFN80, FFN82, FFN82b}, placed the GT centroid at too low excitation energy of 2.0 MeV in the daughter nucleus $^{59}$Fe, and this misplacement led to the enhancement of FFN rates. The suppressed pn-QRPA and shell model electron capture rates are in good agreement with each other. The rates are suggestive of higher value of $Y_{e}$ (electron-to-baryon ratio) and may contribute to a more massive homologously collapsing core resulting in a more energetic shock. It might be interesting for the simulators to check the effect of these suppressed rates on the fine-tuning of the time rate of $Y_{e}$, the concomitant heavy element nucleosynthesis, and, on the energetics of the subsequent shock wave.

ORDMKV: a computer program fitting proportional odds model for multi-state Markov process.  

PubMed

ORDMKV is a computer program designed to fit a multi-state discrete-time Markov model for k-stages disease processes having an ordinal structure. The model consists of k transient states representing the increasing severity of the disease process, and the final state can be optionally chosen to be an absorbing state in cases such as death. The ordinal structure of the stages of the disease is modelled by using ordinal response models. Each row of the one-step transition probability matrix is modelled using a proportional odds model based on the cumulative transition probabilities. By using these ordinal response models, the number of parameters used to model the disease process can be reduced significantly not only with respect to a general discrete-time model, but also compared with a parsimonuos continuous-time model. A restricted model can be fitted by assuming that the effect of the covariables in the cumulative probability has common regression coefficients in all stages of the disease process. This assumption, if it holds, reduces the number of regression coefficients associated with each covariate to only one. The regression coefficients of this model are estimated via the method of maximum likelihood, using a quasi-Newton optimization algorithm. When the last state is considered as an absorbing state, it is possible to compute survival curves from the transient states of the process. The program was written in standard FORTRAN 77 and is illustrated using a four-state model to determine factors influencing diabetic retinopathy in young subjects with insulin-dependent diabetes mellitus.

Electron capture strength on odd- A nucleus 59Co in explosive astrophysical environment

The pn-QRPA calculated a total B( GT +) strength of 3.3 for 59Co to be compared with the shell model value of 2.5 and the 1.9±0.1 in the ( n, p) charge-exchange reaction. Aufderheide et al. (1993) extracted total strength equaling 2.4±0.3. The placement of GT centroid at 5.6 MeV by the pn-QRPA model is in reasonable agreement with the shell model centroid at 5.1 MeV whereas the measured GT centroid was placed at 4.4±0.3 MeV in the ( n, p) experiment.

The suppressed pn-QRPA and shell model electron capture rates are in good agreement with each other. The rates are suggestive of higher value of Y e (electron-to-baryon ratio) and may contribute to a more massive homologously collapsing core resulting in a more energetic shock. It might be interesting for the simulators to check the effect of these suppressed rates on the fine-tuning of the time rate of Y e , the concomitant heavy element nucleosynthesis, and, on the energetics of the subsequent shock wave.
