Chiral Odd GPDs  

NASA Astrophysics Data System (ADS)

Nucleon spin structure, transversity and the tensor charge are of central importance to understanding the role of QCD in hadronic physics. A new approach to measuring orbital angular momenta of quarks in the proton via twist 3 GPDs is shown. The "flexible parametrization" of chiral even GPDs is reviewed and its transformation into the chiral odd sector is discussed. The resulting parametrization is applied to recent data on ?0 and ? electroproduction.

Covariant Energy Density Functionals: Time-Odd Channel Investigated  

SciTech Connect

Time-odd mean fields (nuclear magnetism) are investigated 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. As a result, time-odd mean fields affect odd-even mass differences. They also have a 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 and considerably affect the possibilities of their experimental observation.

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.

Magnetic moments of odd-odd spherical nuclei  

E-print Network

Magnetic moments of more than one hundred odd-odd spherical nuclei in ground and excited states are calculated within the self-consistent TFFS based on the EDF method by Fayans {\\it et al}. We limit ourselves to nuclei with a neutron and a proton particle (hole) added to the magic or semimagic core. A simple model of no interaction between the odd nucleons is used. In most the cases we analyzed, a good agreement with the experimental data is obtained. Several cases are considered where this simple model does not work and it is necessary to go beyond. The unknown values of magnetic moments of many unstable odd and odd-odd nuclei are predicted including sixty values for excited odd-odd nuclei.

Time-odd correlation in a neutron reflectometry experiment

We find that neutron transmission of magnetic systems with the noncollinear magnetization contains a time-odd correlation. The neutron reflection from such a system violates detailed balance. Time-odd correlation is shown to violate T-invariance even in the presence of an irreversibly produced by losses and described by the imaginary part in the neutron-matter interaction.

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.

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.

Odds of observing the multiverse  

E-print Network

Eternal inflation predicts our observable universe lies within a bubble (or pocket universe) embedded in a volume of inflating space. The interior of the bubble undergoes inflation and standard cosmology, while the bubble walls expand outward and collide with other neighboring bubbles. The collisions provide either an opportunity to make a direct observation of the multiverse or, if they produce unacceptable anisotropy, a threat to inflationary theory. The probability of an observer in our bubble detecting the effects of collisions has an absolute upper bound set by the odds of being in the part of our bubble that lies in the forward light-cone of a collision; in the case of collisions with bubbles of identical vacua, this bound given by the bubble nucleation rate times ($H_{\\rm{O}}/H_{\\rm{I}})^2$, where $H_{\\rm{O}}$ is the Hubble scale outside the bubbles and $H_{\\rm{I}}$ is the scale of the second round of inflation that occurs inside our bubble. Similar results were obtained by Freigovel \\emph{et al.} using a different method for the case of collisions with bubbles of much larger cosmological constant; here it is shown to hold in the case of collisions with identical bubbles as well. A significant error in a previous draft was corrected in order to arrive at this result.

P-odd and CP-odd Four-Quark Contributions to Neutron EDM  

E-print Network

In a class of beyond-standard-model theories, CP-odd observables, such as the neutron electric dipole moment, receive significant contributions from flavor-neutral P-odd and CP-odd four-quark operators. However, considerable uncertainties exist in the hadronic matrix elements of these operators strongly affecting the experimental constraints on CP-violating parameters in the theories. Here we study their hadronic matrix elements in combined chiral perturbation theory and nucleon models. We first classify the operators in chiral representations and present the leading-order QCD evolutions. We then match the four-quark operators to the corresponding ones in chiral hadronic theory, finding symmetry relations among the matrix elements. Although this makes lattice QCD calculations feasible, we choose to estimate the non-perturbative matching coefficients in simple quark models. We finally compare the results for the neutron electric dipole moment and P-odd and CP-odd pion-nucleon couplings with the previous studies using naive factorization and QCD sum rules. Our study shall provide valuable insights on the present hadronic physics uncertainties in these observables.

Enhanced T-odd, P-odd electromagnetic moments in reflection asymmetric nuclei  

SciTech Connect

Collective P- and T-odd moments produced by parity and time invariance violating forces in reflection asymmetric nuclei are considered. The enhanced collective Schiff, electric dipole, and octupole moments appear due to the mixing of rotational levels of opposite parity. These moments can exceed single-particle moments by more than 2 orders of magnitude. The enhancement is due to the collective nature of the intrinsic moments and the small energy separation between members of parity doublets. In turn these nuclear moments induce enhanced T- and P-odd effects in atoms and molecules. A simple estimate is given and a detailed theoretical treatment of the collective T-, P-odd electric moments in reflection asymmetric, odd-mass nuclei is presented. In the present work we improve on the simple liquid drop model by evaluating the Strutinsky shell correction and include corrections due to pairing. Calculations are performed for octupole deformed long-lived odd-mass isotopes of Rn, Fr, Ra, Ac, and Pa and the corresponding atoms. Experiments with such atoms may improve substantially the limits on time reversal violation. {copyright} {ital 1997} {ital The American Physical Society}

Reproducing kernel Hilbert spaces with odd kernels in price prediction.  

PubMed

For time series of futures contract prices, the expected price change is modeled conditional on past price changes. The proposed model takes the form of regression in a reproducing kernel Hilbert space with the constraint that the regression function must be odd. It is shown how the resulting constrained optimization problem can be reduced to an unconstrained one through appropriate modification of the kernel. In particular, it is shown how odd, even, and other similar kernels emerge naturally as the reproducing kernels of Hilbert subspaces induced by respective symmetry constraints. To test the validity and practical usefulness of the oddness assumption, experiments are run with large real-world datasets on four futures contracts, and it is demonstrated that using odd kernels results in a higher predictive accuracy and a reduced tendency to overfit.

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

E-print Network

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 $SO^{F}(2\\Omega)\\subset OSp(2\\Omega/12,R)$, to the boson core which states belong to an $Sp^{B}(12,R)$ 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.

Signature inversion phenomena in odd-odd 182Au

High-spin states in the odd-odd 182Au nucleus have been investigated using the 152Sm(35Cl, 5n?)182Au reaction through X-? and ?-?-t coincidence measurements. Rotational bands based on the ?h9/2??i13/2 and ?i13/2??i13/2 configurations have been identified. It is found that the two bands show characteristics of low-spin signature inversion. The observed signature inversion can be well reproduced by pairing-deformation self-consistent cranking Woods-Saxon calculations.

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.

High-spin states in 184Au have been populated via the 149Sm(29Si, 4ngamma) 184Au reaction at a beam energy of 140 MeV. Three- or higher-fold gamma-ray coincidences have been measured using the multidetector array of GASP. A rotational band built on the 11- oblate pih11/2-1otimesnui13/2-1 structure has been newly observed, similar to those reported in 186-194Au. This result extends the knowledge of shape coexistence to the currently lightest odd-odd Au isotope.

Reflection asymmetry in odd-A and odd-odd actinium nuclei  

SciTech Connect

Theoretical calculations and measurements indicate that octupole correlations are at a maximum in the ground states of the odd-proton nuclei Ac and Pa. It has been expected that odd-odd nuclei should have even larger amount of octupole-octupole correlations. We have recently made measurements on the structure of {sup 224}Ac. Although spin and parity assignments could not be made, two bands starting at 354.1 and 360.0 keV have properties characteristic of reflection asymmetric shape. These two bands have very similar rotational constants and also similar alpha decay rates, which suggest similarity between the wavefunctions of these bands. These signatures provide evidence for octupole correlations in these nuclides.

De-excitation Energy of Superdeformed Secondary Minima of Odd-Odd Au Isotopes and Its Sensitivity to the Density Dependence of Symmetry Energy  

NASA Astrophysics Data System (ADS)

The de-excitation energy of superdeformed secondary minima of odd-odd Au isotopes is investigated using the relativistic mean field model with the inclusion of the isoscalar-isovector coupling. It is shown that the de-excitation energies of superdeformed secondary minima relative to the ground states can serve as a significant probe to the density dependence of the symmetry energy.

BOOK REVIEW: The Odd Quantum  

NASA Astrophysics Data System (ADS)

The Odd Quantum is aiming to be odd. Falling between being a quantum mechanics textbook and a `popular' science book, it aims to convey something of the substance of quantum mechanics without being overly technical or professional. It does not shy away from the mathematics of the subject or resort solely to analogy and metaphor, as so often is the case. Books aimed at the lay reader tend to take on a particular aspect of quantum mechanics, for example, wave-particle duality, and can do little more than hint at the complexity of the subject. This book is more than a textbook on quantum mechanics; it gives the reader a comprehensive account of history and an appreciation of the nature of quantum mechanics. The introductory chapters deal with the earlier part of the century and the thinking of that time. The approach is familiar, as are the stories that Treiman tells, but he also manages to convey the speed with which ideas changed and the excitement this brought to the physics community. Classical ideas of force and energy are dealt with succinctly but with sufficient depth to set up the reader for what is to come; Maxwell's equations and a brief glimpse at relativity are included. This is followed by a brief description of what the author terms the `old' quantum mechanics, in effect a highly readable tour around black body radiation and spectroscopy and the models of the atom that emerged from them. The `new' quantum mechanics begins about a third of the way through the book, and in a chapter entitled `Foundations' starts gently but rapidly moves into a detailed mathematical treatment. This section, of necessity, relapses into the style of a textbook and covers a lot of ground quickly. It is at this point that the non-specialist popular science readers for whom Treiman has written this book may become a little bemused. Concepts such as non-degeneracy and operators come thick and fast. It is difficult to imagine an educated non-physicist with little mathematical ability keeping track of the equations and their meaning. However, the text continues to be accessible and moves swiftly from `quantum classics' such as the harmonic oscillator to electrical conductivity and the collapse of stars. Reassuringly, Treiman takes time out to ask `What's going on?' where he considers the question of how probabilities get converted into `facts' when things are measured. His own fascination with the subject comes through as he considers the different interpretations of quantum mechanics. The chapter on `building blocks' starts in 1932 when ` ... it could seem that all the basic building blocks of the whole world were at last in hand'. Swiftly and succinctly it moves through to the standard model, acknowledging that a closer look would ` ... quickly carry us far afield into highly technical thickets'. The final chapter tackles the more difficult subject of quantum field theory. This is a very swift journey through quantum electrodynamics and quantum chromodynamics. It is the final summary that stands out, however. The author reminds us what to marvel about: the miracles of quantum theory that are ` ... outrageous to common sense and intuition'. This is a useful book for any science department. It will be of particular use to those of us who studied the subject some time ago and who need to refresh their memories, for example teachers of A-level physics. The asides about `what is going on' and the history that is included make it a `book' rather than a `textbook'. First-year undergraduates, or just possibly motivated and mathematically able A-level students, would also benefit. Beware, however. The mathematics is not trivial and you would arguably need to have met it before in order to cope. Although the book occasionally relapses into textbook style you are left with a sense of the wonder of the subject and an appreciation of the beauty of the mathematics that underpins it.

High-spin states in odd-odd 174Re  

NASA Astrophysics Data System (ADS)

High-spin states in the odd-odd 174Re have been investigated via the 152Sm(27Al, 5n?)174Re reaction with the help of excitation function, x-?, and ?-? coincidence measurements. Five rotational bands have been observed and their configurations were assigned based on alignments, band crossing frequencies, electromagnetic properties, and the estimated bandhead excitation energies. Low-spin signature inversion has been identified in the two-quasiparticle bands built on ?h11/2??i13/2, ?h9/2??i13/2, and ?1/2-[541]??5/2-[512] configurations. E2 interband transitions were analyzed with band-mixing calculations giving information on shapes and shape driving effects for the bands of interest.

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.

Odd nitrogen production by meteoroids  

NASA Technical Reports Server (NTRS)

The process by which odd nitrogen species (atomic nitrogen and nitric oxide) are formed during atmospheric entry of meteoroids is analyzed theoretically. An ablating meteoroid is assumed to be a point source of mass with a continuum regime evolving in its wake. The amounts of odd nitrogen species, produced by high-temperature reactions of air in the continuum wake, are calculated by numerical integration of chemical rate equations. Flow properties are assumed to be uniform across the wake, and 29 reactions involving five neutral species and five singly ionized species are considered, as well as vibrational and electron temperature nonequilibrium phenomena. The results, when they are summed over the observed mass, velocity, and entry-angle distribution of meteoroids, provide odd-nitrogen-species annual global production rates as functions of altitude. The peak production of nitric oxide is found to occur at an altitude of about 85 km; atomic nitrogen production peaks at about 95 km. The total annual rate for nitric oxide is 40 million kg; for atomic nitrogen it is 170 million kg.

Soil clay content underlies prion infection odds  

PubMed Central

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.

This formalism is applied to the case of light-cone wave functions in a constituent quark model. Numerical results for the four chiral-odd generalized parton distributions at the hadronic scale are shown in different kinematics. In the forward limit we derive the transversity distribution, the tensor charge and the angular momentum sum rule for quarks with transverse polarization in an unpolarized nucleon.

A four-quasiparticle isomer (t/sub 1/2/ = 88 +- 8 ns) was located at 2256.3 keV and is characterized as an oblate girdle about the basic prolate core.

Whence the odd-even staggering in nuclear binding?  

E-print Network

We explore the systematics of odd-even mass staggering with a view to identifying the physical mechanisms responsible. The BCS pairing and mean field contributions have A- and number parity dependencies which can help disentangle the different contributions. This motivates the two-term parametrization c_1 + c_2/A as a theoretically based alternative to the inverse power form traditionally used to fit odd-even mass differences. Assuming that the A-dependence of the BCS pairing is weak, we find that mean-field contributions are dominant below mass number A~40 while BCS pairing dominates in heavier nuclei.

Solar disturbances and mesospheric odd nitrogen  

NASA Technical Reports Server (NTRS)

The odd nitrogen (NOx) abundance of the high latitude mesosphere exhibits a large variability in response to energetic particle precipitation. Model calculations for a very large particle event predict increases in the NOx mixing ratio that can exceed a factor of ten over time periods of the order of one week in the summer hemisphere. A more typical sized event can still lead to an enhancement of a factor of three in summer. Relative changes in the winter hemisphere are less dramatic due to a larger ambient NOx mixing ratio predicted here. However, a factor of two increase in NOx is possible during a very large event. Owing to the large variability, it is difficult to define a physically meaningful mean state profile in the high latitude mesosphere. Rather, the NOx abundance likely displays an erratic behavior which is correlated with the level of solar activity.

General parity-odd CMB bispectrum estimation  

E-print Network

We develop a methodology for estimating parity-odd bispectra in the cosmic microwave background (CMB). This is achieved through the extension of the original separable modal methodology to parity-odd bispectrum domains ($\\ell_1 + \\ell_2 + \\ell_3 = {\\rm odd}$). Through numerical tests of the parity-odd modal decomposition with some theoretical bispectrum templates, we verify that the parity-odd modal methodology can successfully reproduce the CMB bispectrum, without numerical instabilities. We also present simulated non-Gaussian maps produced by modal-decomposed parity-odd bispectra, and show the consistency with the exact results. Our new methodology is applicable to all types of parity-odd temperature and polarization bispectra.

We estimate that such an experiment may be sensitive to c0j coefficients as small as 10-18.

Flexible Parametrization of Generalized Parton Distributions: The Chiral-Odd Sector  

E-print Network

We present a physically motivated parameterization of the chiral-odd generalized parton distributions. The parametrization is an extension of our previous one in the chiral-even sector which was based on the reggeized diquark model. While for chiral even generalized distributions a quantitative fit with uncertainty estimation can be performed using deep inelastic scattering data, nucleon electromagnetic, axial and pseudoscalar form factors measurements, and all available deeply virtual Compton scattering data, the chiral-odd sector is far less constrained. While awaiting the analysis of measurements on pseudoscalar mesons exclusive electroproduction which are key for the extraction of chiral odd GPDs, we worked out a connection between the chiral-even and chiral-odd reduced helicity amplitudes using Parity transformations. The connection works for a class of models including two-components models. This relation allows us to estimate the size of the various chiral odd contributions and it opens the way for future quantitative fits.

Odd orders in Shor's factoring algorithm  

NASA Astrophysics Data System (ADS)

Shor's factoring algorithm (SFA) finds the prime factors of a number, , exponentially faster than the best known classical algorithm. Responsible for the speedup is a subroutine called the quantum order finding algorithm (QOFA) which calculates the order—the smallest integer, , satisfying , where is a randomly chosen integer coprime to (meaning their greatest common divisor is one, ). Given , and with probability not 1/2, the factors are given by and . For odd , it is assumed that the factors cannot be found (since is not generally integer) and the QOFA is relaunched with a different value of . But a recent paper (Martin-Lopez et al. Nat. Photonics 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.

The effect of particle precipitation events on the neutral and ion chemistry of the middle atmosphere. II - Odd hydrogen

A one dimensional time-dependent model of the neutral and ion chemistry of the middle atmosphere has been used to examine the production of odd hydrogen (H, OH, and HO2) during charged particle precipitation. At altitudes above about 65 km, odd hydrogen production depends on the ionization rate, and the atomic oxygen and water vapor densities. Odd hydrogen production is shown to exhibit diurnal and other time dependent variations during such an event at these altitudes, and the assumption that two odd hydrogen particles are always produced per ionization is reexamined.

The calculation of correlation functions for $\\beta=1$ random matrix ensembles, which can be carried out using Pfaffians, has the peculiar feature of requiring a separate calculation depending on the parity of the matrix size N. This same complication is present in the calculation of the correlations for the Ginibre Orthogonal Ensemble of real Gaussian matrices. In fact the methods used to compute the $\\beta=1$, N odd, correlations break down in the case of N odd real Ginibre matrices, necessitating a new approach to both problems. The new approach taken in this work is to deduce the $\\beta=1$, N odd correlations as limiting cases of their N even counterparts, when one of the particles is removed towards infinity. This method is shown to yield the correlations for N odd real Gaussian matrices.

A comparison of marginal odds ratio estimators.  

PubMed

Uses of the propensity score to obtain estimates of causal effect have been investigated thoroughly under assumptions of linearity and additivity of exposure effect. When the outcome variable is binary relationships such as collapsibility, valid for the linear model, do not always hold. This article examines uses of the propensity score when both exposure and outcome are binary variables and the parameter of interest is the marginal odds ratio. We review stratification and matching by the propensity score when calculating the Mantel-Haenszel estimator and show that it is consistent for neither the marginal nor conditional odds ratio. We also investigate a marginal odds ratio estimator based on doubly robust estimators and summarize its performance relative to other recently proposed estimators under various conditions, including low exposure prevalence and model misspecification. Finally, we apply all estimators to a case study estimating the effect of Medicare plan type on the quality of care received by African-American breast cancer patients. PMID:25006032

Odd orders in Shor's factoring algorithm  

E-print Network

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.

Social adjustment among Taiwanese children with symptoms of ADHD, ODD, and ADHD comorbid with ODD.  

PubMed

This study examined social problems at school and relationships with peers, siblings, mothers, and fathers among children with ADHD only (n = 41), ODD only (n = 14), ADHD + ODD (n = 47), and normal controls (n = 204) from a school-based sample of 2,463 first to ninth graders in Taiwan. ADHD and ODD symptoms were determined by teacher and mother reports on the Conners' Rating Scales and social adjustment problems were assessed by mother reports on the Social Adjustment Inventory for Children and Adolescents. Results indicated that relative to normal controls, children with ADHD + ODD displayed greater levels of social adjustment problems across domains (i.e., school, peers, siblings, and parents) while children with ADHD were significantly more impaired only in social adjustment at schools and children with ODD were more impaired only in social adjustment at home. Some similarities and differences in our findings, in relation to the Western literature, were discussed. PMID:20886286

ODD Modes of a New Transmission Line Based on Semi-open Dielectric Rod  

NASA Astrophysics Data System (ADS)

An original transmission line based on a planar waveguide splitter with central dielectric filling is considered. A rigorous electrodynamics model is presented for calculating propagation parameters of odd eigenmodes. It was determined that the physics of the wave processes of the line for odd modes is identical to the physics of closed structures, though the structure geometry is of semi-open character. Numerical experiments prove that new line is very promising for different millimeter wave applications, such as band pass filters, test fixture, antennae and three-dimensional integrated circuits (TDIC).

PARITY ODD BUBBLES IN HOT QCD.  

SciTech Connect

We consider the topological susceptibility for an SU(N) gauge theory in the limit of a large number of colors, N {r_arrow} {infinity}. At nonzero temperature, the behavior of the topological susceptibility depends upon the order of the deconfining phase transition. The most interesting possibility is if the deconfining transition, at T = T{sub d}, is of second order. Then we argue that Witten's relation implies that the topological susceptibility vanishes in a calculable fashion at Td. As noted by Witten, this implies that for sufficiently light quark masses, metastable states which act like regions of nonzero {theta}--parity odd bubbles--can arise at temperatures just below T{sub d}. Experimentally, parity odd bubbles have dramatic signatures: the {eta}{prime} meson, and especially the {eta} meson, become light, and are copiously produced. Further, in parity odd bubbles, processes which are normally forbidden, such as {eta} {r_arrow} {pi}{sup 0}{pi}{sup 0}, are allowed. The most direct way to detect parity violation is by measuring a parity odd global asymmetry for charged pions, which we define.

Properties of odd nuclei and the impact of time-odd mean fields: A systematic Skyrme-Hartree-Fock analysis  

E-print Network

We present a systematic analysis of the description of odd nuclei by the Skyrme-Hartree-Fock approach augmented with pairing in BCS approximation and blocking of the odd nucleon. Current and spin densities in the Skyrme functional produce time-odd mean fields (TOMF) for odd nuclei. Their effect on basic properties (binding energies, odd-even staggering, separation energies and spectra) is investigated for the three Skyrme parameterizations SkI3, SLy6, and SV-bas. About 1300 spherical and axially-deformed odd nuclei with 16 odd nuclei is of varying quality depending on the nucleus.

Piezoelectricity and ferroelectricity in odd-odd nylons with long alkane segments  

NASA Astrophysics Data System (ADS)

Piezoelectricity and ferroelectricity in odd-odd nylon 11,11 and nylon 13,13 are detected. The results indicate that the ?-phase is responsible for the high piezoelectric and ferroelectric response. The piezoelectric strain coefficient, d33, as high as -3.9 and -4.1 pC/N is obtained at room temperature for stretched nylon 11,11 and nylon 13,13 films, respectively. The coercive electric field, Ec, values of about 55 and 88 MV/m are obtained for nylon 11,11 and nylon 13,13 films, respectively. And a remanent polarization, Pr, about 40 mC/m2 has been found in both films. Compared with nylon 11,11, the lower coercive electric field (Ec) in nylon 13,13 is attributed to its longer alkyl chains. These odd-odd nylons have the potential in electroactive applications.

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.

Odd-even effect of melting finite polymer film on square lattice  

E-print Network

Two dimensional film system bears many exotic thermodynamics behaviors. We proposed a mathematical physics model to explore how the melting temperature of a two dimensional mathematical dimer film depends on the odd-eveness of the finite width of dimer film. A weak external bond between dimers is introduced into the classical dimer model in this dimer film. We derived a general equation of melting temperature and applied it for computing the melting temperature of a dimer film covering a finite square lattice. The melting temperature is proportional to the external bonding energy that we assume it binds neighboring dimers together and proportional to the inverse of entropy per site. Further more, it shows fusing two small rectangular dimer film with odd number of length into one big rectangular film gains more entropy than fusing two small rectangles with even number of length into the same big rectangle. Fusing two small toruses with even number of length into one big torus reduces entropy. Fusing two small toruses with odd number of length increases the entropy. Thus two dimer films with even number of length repel each other, two dimer films with odd length attract each other. The odd-even effect is also reflected on the correlation function of two topologically distinguishable loops in a torus surface. The entropy of finite system dominates odd-even effect. This model has straightforward extension to longer polymers and three dimensional systems.

Simple methods in the frame work of the broken pair model have been worked out for odd-odd nuclei. The reliability of the model has been tested by reproducing the shell model results of limiting cases in which the broken pair model exactly coincides with the shell model. The model is then applied to calculate the energy levels of some nuclei in the Zirconium region. The model results compare reasonably well with the shell model as well as with the experimental data.

Low-frequency noise in an oscillator normally produces two LF noise sidebands around the center frequencyf_{0}of the oscillator. It was shown experimentally that these noise sidebands can be eliminated by using an oscillator circuit with an odd-symmetrical characteristic. A simple theory based on the van der Pol approach to oscillators can explain the observed effects.

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.

Regularization of odd-dimensional AdS gravity: Kounterterms  

E-print Network

As an alternative to the Dirichlet counterterms prescription, I introduce the concept of Kounterterms as the boundary terms with explicit dependence on the extrinsic curvature K_{ij} that regularize the AdS gravity action. Instead of a Dirichlet boundary condition on the metric, a suitable choice of the boundary conditions --compatible with any asymptotically AdS (AAdS) spacetime-- ensures a finite action principle for all odd dimensions. Background-independent conserved quantities are obtained as Noether charges associated to asymptotic symmetries and their general expression appears naturally split in two parts. The first one gives the correct mass and angular momentum for AAdS black holes and vanishes identically for globally AdS spacetimes. Thus, the second part is a covariant formula for the vacuum energy in AAdS spacetimes and reproduces the results obtained by the Dirichlet counterterms method in a number of cases. It is also shown that this Kounterterms series regularizes the Euclidean action and recovers the correct black hole thermodynamics in odd dimensions.

In the latter case, useful suggestions for phenomenological analyses and an interesting result for normal and transverse polarization are derived.

Odd Parity Perturbations of the Self-Similar LTB Spacetime  

E-print Network

We consider the behaviour of odd-parity perturbations of those self-similar Lema\\^{i}tre-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. Taken on its own, this result does not support cosmic censorship; however a full perturbation of this spacetime would include even parity perturbations, so we cannot conclude that this spacetime is stable to all linear perturbations.

Torsion, parity-odd response, and anomalies in topological states

We study the response of a class of topological systems to electromagnetic and gravitational sources, including torsion and curvature. By using the technology of anomaly polynomials, we derive the parity-odd response of a massive Dirac fermion in d =2 +1 and d =4 +1 , which provides a simple model for a topological insulator. We discuss the covariant anomalies of the corresponding edge states, from a Callan-Harvey anomaly inflow, as well as a Hamiltonian spectral flow point of view. We also discuss the applicability of our results to other systems such as Weyl semimetals. Finally, using dimensional reduction from d =4 +1 , we derive the effective action for a d =3 +1 time-reversal invariant topological insulator in the presence of torsion and curvature, and discuss its various physical consequences.

This scattering length is protected against contributions of m_s in the chiral expansion, in the sense that the corrections to the current algebra result are of order M_pi^2. In view of the planned lifetime measurement on pi K atoms at CERN it is important to understand the size of these corrections.

Even and odd generalized hypergeometric coherent states  

E-print Network

In this paper, we investigate a large class of generalized hypergeometric states $|p,q,z\\rangle$, depending on a complex variable $z$ and two sets of parameters, $(a_1,\\cdots,a_p)$ and $(b_1,\\cdots,b_q)$. Even and odd generalized hypergeometric states $|p,q,z\\rangle_e$ and $|p,q,z\\rangle_o$ are also defined and analyzed. The moment problem is solved by the Mellin transform techniques. For particular values of $p$ and $q$, the photon-counting statistics, quantum optical properties and geometry of these states are discussed.

Odd-parity D states in He.  

NASA Technical Reports Server (NTRS)

The states considered lie below the n = 2 threshold of He(+) and decay radiatively to the lower states. The most general D-state wave function of odd parity of two electrons is examined. The results presented are optimized with respect to four nonlinear parameters for 112 terms. A mass-polarization correction is given for all the states listed. The positions of the D states, including the reduced mass and the mass-polarization corrections, with respect to the ground state of He are reported.

Comparison of model results transporting the odd nitrogen family with results transporting separate odd nitrogen species  

NASA Technical Reports Server (NTRS)

A fast two-dimensional residual circulation stratospheric family transport model, designed to minimize computer requirements, is developed. The model was used to calculate the ambient and perturbed atmospheres in which odd nitrogen species are transported as a family, and the results were compared with calculations in which HNO3, N2O5, ClONO2, and HO2NO2 are transported separately. It was found that ozone distributions computed by the two models for a present-day atmosphere are nearly identical. Good agreement was also found between calculated species concentrations and the ozone response, indicating the general applicability of the odd-nitrogen family approximations.

Enhancement of the CP-odd effect in the nuclear electric dipole moment of $^6$Li  

E-print Network

We calculate for the first time the electric dipole moment (EDM) of the $^6$Li nucleus within the alpha + p + n three-body cluster model using the Gaussian expansion method, assuming the one meson exchange P, CP-odd nuclear forces. It is found that the EDM of the $^6$Li is 2 times more sensitive on the isovector pion exchange P, CP-odd nuclear force than the deuteron EDM, due to the CP-odd interaction between the nucleons and the alpha cluster. The $^9$Be EDM is also calculated in the same framework as an alpha + alpha + n three-body system. We also test the ab initio calculation of the EDM of the deuteron, $^3$H and $^3$He nuclei using the realistic Argonne $v18$ nuclear force. In the ab initio calculations, good agreements with previous studies are obtained. We finally discuss the prospects for the new physics beyond the standard model.

The ODD protocol: A review and first update  

USGS Publications Warehouse

The 'ODD' (Overview, Design concepts, and Details) protocol was published in 2006 to standardize the published descriptions of individual-based and agent-based models (ABMs). The primary objectives of ODD are to make model descriptions more understandable and complete, thereby making ABMs less subject to criticism for being irreproducible. We have systematically evaluated existing uses of the ODD protocol and identified, as expected, parts of ODD needing improvement and clarification. Accordingly, we revise the definition of ODD to clarify aspects of the original version and thereby facilitate future standardization of ABM descriptions. We discuss frequently raised critiques in ODD but also two emerging, and unanticipated, benefits: ODD improves the rigorous formulation of models and helps make the theoretical foundations of large models more visible. Although the protocol was designed for ABMs, it can help with documenting any large, complex model, alleviating some general objections against such models.

W' signatures with odd Higgs particles  

NASA Astrophysics Data System (ADS)

We point out that W ' bosons may decay predominantly into Higgs particles associated with their broken gauge symmetry. We demonstrate this in a renormalizable model where the W ' and W couplings to fermions differ only by an overall normalization. This "meta-sequential" W ' boson decays into a scalar pair, with the charged one subsequently decaying into a W boson and a neutral scalar. These scalars are odd under a parity of the Higgs sector, which consists of a complex bidoublet and a doublet. The W ' and Z ' bosons have the same mass and branching fractions into scalars, and may show up at the LHC in final states involving one or two electroweak bosons and missing transverse energy.

Odd Triplet superconductivity in Superconductor-Ferromagnet hybrid structures  

NASA Astrophysics Data System (ADS)

Since the prediction of a long-range triplet component of the superconducting condensate in ferromagnetic-superconductor (S/F) proximity structures in 2001 [1], the activity in the field has increased considerably, both theoretically and experimentally The coexistence of conventional singlet superconductivity and ferromagnetism in S/F structures is closely related with the appearence of a triplet component of the condensate, which is odd in frequency and even in momentum and therefore insensitive to nonmagnetic impurities. The presence of the triplet component leads to new effects as for example, long-range Josephson coupling in SFS junctions [1], flow of a supercurrent through a half-metallic link [2] and screening of the magnetic moment of ferromagnetic particles embbeded in a superconductor [3]. In this talk I will review the main issues of the odd-triplet superconductivity, its manifestation in physical properties, and briefly discuss the relevant experiments in the field [4].

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.

Odd nitrogen in the mesosphere and thermosphere - Its chemistry and transport  

NASA Technical Reports Server (NTRS)

The atomic nitrogen in the thermosphere, which is produced either in its ground term or in a highly reactive metastable term, reacts with molecular oxygen to form nitric oxide and atomic oxygen. However, nitric oxide is destroyed in reactions with atomic nitrogen in which molecular nitrogen and atomic oxygen is formed. Adopted reactions and rate coefficients for odd nitrogen chemistry are listed in a table. An analysis is conducted of the temperature distribution below 150 km and its effect on the odd nitrogen chemistry. The latitudinal distribution of nitric oxide is discussed. Satellite measurements have shown that nitric oxide concentrations at high latitudes are highly variable in both time and space. Their average concentrations are 3-4 times higher than at mid-latitudes. The measured variation of nitric oxide density as a function of latitude is shown in a graph.

Middle atmosphere heating by exothermic chemical reactions involving odd-hydrogen species  

NASA Technical Reports Server (NTRS)

The rate of heating which occurs in the middle atmosphere due to four exothermic reactions involving members of the odd-hydrogen family is calculated. The following reactions are considered: O + OH yields O2 + H; H + O2 + M yields HO2 + M; H + O3 yields OH + O2; and O + HO2 yields OH + O2. It is shown that the heating rates due to these reactions rival the oxygen-related heating rates conventionally considered in middle-atmosphere models. The conversion of chemical potential energy into molecular translational energy (heat) by these odd-hydrogen reactions is shown to be a significant energy source in the middle atmosphere that has not been previously considered.

Quantum shape-phase transitions in odd-even nuclei are investigated in the framework of the interacting boson-fermion model. Classical and quantum analysis show that the presence of the odd fermion strongly influences the location and nature of the phase transition, especially near the critical point. Experimental evidence for the occurrence of spherical to axially-deformed transitions in odd-proton nuclei Pm, Eu and Tb (Z=61, 63, 65) is presented.

Spectroscopy of the ODD-ODD nucleus 76As and its supersymmetric description  

NASA Astrophysics Data System (ADS)

Gamma rays and conversion electrons following thermal-neutron capture in 75As have been measured using the Ge pair spectrometer PN4, the bent crystal spectrometers GAMS and the ?-spectrometer BILL at the ILL. Coincident ?-rays were recorded at the CEN/SCK Mol, and average resonance capture at En = 2 and 24 keV has been studied at the HFBR of BNL. The neutron binding energy in 76As was determined to be 7328.498 ± 0.075 keV. The resulting level scheme for 76As greatly improves the knowledge on this odd-odd nucleus. The low-lying positive-parity states are discussed in the U(5) limit of the U v(6/12)?U ?(6/12) supersymmetry using the same hamiltonian to describe the quartet 76Se- 77Se- 75As- 76As having the same total number of bosons plus fermions.

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.

Isospin and deformation studies in the odd-odd N=Z nucleus {sup 54}Co  

SciTech Connect

High-spin states in the odd-odd N=Z nucleus {sup 54}Co have been investigated by the fusion-evaporation reaction {sup 28}Si({sup 32}S,1{alpha}1p1n){sup 54}Co. Gamma-ray information gathered with the Ge detector array Gammasphere was correlated with evaporated particles detected in the charged particle detector system Microball and a 1{pi} neutron detector array. A significantly extended excitation scheme of {sup 54}Co is presented, which includes a candidate for the isospin T=1, 6{sup +} state of the 1f{sub 7/2}{sup -2} multiplet. The results are compared to large-scale shell-model calculations in the fp shell. Effective interactions with and without isospin-breaking terms have been used to probe isospin symmetry and isospin mixing. A quest for deformed high-spin rotational cascades proved negative. This feature is discussed by means of cranking calculations.

Spectroscopy of the odd-odd fp-shell nucleus 52Sc from secondary fragmentation  

E-print Network

The odd-odd fp-shell nucleus 52Sc was investigated using in-beam gamma-ray spectroscopy following secondary fragmentation of a 55V and 57Cr cocktail beam. Aside from the known gamma-ray transition at 674(5)keV, a new decay at E_gamma=212(3) keV was observed. It is attributed to the depopulation of a low-lying excited level. This new state is discussed in the framework of shell-model calculations with the GXPF1, GXPF1A, and KB3G effective interactions. These calculations are found to be fairly robust for the low-lying level scheme of 52Sc irrespective of the choice of the effective interaction. In addition, the frequency of spin values predicted by the shell model is successfully modeled by a spin distribution formulated in a statistical approach with an empirical, energy-independent spin-cutoff parameter.

To this end, we perform HFBCS calculations for even and odd semi-magic Tin and Lead isotopes together with even and odd Z isotones with $N$= 50 and 82. The filling approximation is applied to the last unoccupied particle in odd nuclei. Comparisons with the experimental data show a clear manifestation of the isospin dependent pairing correlations in both proton and neutron pairing gaps.

Multi-quasiparticle structures up to spin ~44{dirac_h} 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} 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.

Beating the odds--surviving extreme hyperkalemia.  

PubMed

Severe hyperkalemia (>7 mmol/L) is a medical emergency because of possible fatal arrhythmias. We here report the case of a 58-year-old woman surviving extreme hyperkalemia (>10 mmol/L). The patient with a history of congestive heart failure, a DDD pacemaker and mild chronic renal insufficiency was admitted with progressive weakness and sudden onset of hypotension and bradycardia in the absence of any pacemaker action. Laboratory tests revealed an extreme serum potassium level of 10.1 mmol/L, with a slightly elevated serum creatinine of 149 ?mol/L. Treatment with norepinephrine, sodium bicarbonate, and insulin improved both the hemodynamic situation and the serum potassium with subsequent regaining pacemaker actions even before additional hemodialysis normalized the potassium level. A thorough investigation demonstrated that several mechanisms contributed to the extreme potassium level: urinalysis and a low transtubular potassium gradient in the presence of metabolic acidosis with normal anion gap pointed to preexisting interstitial nephritis, with renal tubular acidosis type IV as the predisposing factor, whereas several drugs and acute impairment of renal function contributed to the dangerous situation. Despite the odds for fatal outcome, the patient recovered completely, and long-term management was initiated to prevent recurrent hyperkalemia. PMID:21030184

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.

Gear Durability Shown To Be Improved by Superfinishing  

NASA Technical Reports Server (NTRS)

Gears, bearings, and similar mechanical elements transmit loads through contacting surfaces. At the NASA Glenn Research Center at Lewis Field, we postulated that the fatigue lives of gears could be improved by providing smoother tooth surfaces. A superfinishing process was applied to a set of conventionally ground, aerospace-quality gears. This process produced a highly polished, mirrorlike surface as shown in the preceding photograph. The surface fatigue lives of both superfinished and conventionally ground gears were measured by experiments. The superfinished gears survived about four times longer than the conventionally ground gears. These superfinished gears were produced from conventionally ground, aerospace-quality gears whose geometry had been inspected. The gears were superfinished by placing them in a vibrating bath consisting of water, detergent, abrasive powder, and small pieces of zinc. Upon removal from the bath, the surfaces were highly polished, as depicted in the preceding photograph. The gears were again inspected, and dimensional measurements made before and after the superfinishing operation were compared. Superfinishing removed the peaks of the grinding marks and left a much smoother surface. Profile and spacing checks proved that the overall gear tooth shape was not affected in any harmful way. Superfinishing uniformly removed approximately 2.5 microns from each surface.

The competition between alpha decay and spontaneous fission in odd-even and odd-odd nuclei in the range 99 \\leg Z \\leg 129  

E-print Network

The predictions on the mode of decay of the odd-even and odd-odd isotopes of heavy and superheavy nuclei with Z = 99-129, in the range 228 \\leg A \\leg 336, have been done within the Coulomb and proximity potential model for deformed nuclei (CPPMDN). A comparison of our calculated alpha half lives with the values computed using other theoretical models shows good agreement with each other. An extensive study on the spontaneous fission half lives of all the isotopes under study has been performed to identify the long-lived isotopes in the mass region. The study reveals that the alpha decay half lives and the mode of decay of the isotopes with Z = 109, 111, 113, 115 and 117, evaluated using our formalisms, agrees well with the experimental observations. As our study on the odd-even and odd-odd isotopes of Z = 99-129 predicts that, the isotopes $^{238,240-254}$99, $^{244,246-258}$101, $^{248,250,252-260,262}$103, $^{254,256,258-262,264}$105, $^{258,260,262-264,266}$107, $^{262,264,266-274}$109, $^{266,268-279}$11...

Massive and massless higher spinning particles in odd dimensions  

NASA Astrophysics Data System (ADS)

We study actions for massive bosonic particles of higher spins by dimensionally reducing an action for massless particles. For the latter we take a model with a SO( N) extended local supersymmetry on the worldline, that is known to describe massless (conformal) particles of higher spins in flat spacetimes of even dimensions. Dimensional reduction produces an action for massive spinning particles in odd dimensions. The field equations that emerge in a quantization à la Dirac are shown to be equivalent to the Fierz-Pauli ones. The massless limit generates a multiplet of massless states with higher spins, whose first quantized field equations have a geometric form with fields belonging to various types of Young tableaux. These geometric equations can be partially integrated to show their equivalence with the standard Fronsdal-Labastida equations. We covariantize our model to check whether an extension to curved spacetimes can be achieved. Restricting to (A)dS spaces, we find that the worldline gauge algebra becomes nonlinear, but remains first class. This guarantees consistency on such backgrounds. A light cone analysis confirms the presence of the expected propagating degrees of freedom. A covariant analysis is worked out explicitly for the massive case, which is seen to give rise to the Fierz-Pauli equations extended to (A)dS spaces. It is worth noting that in D = 3 the massless limit of our model with N ? ? has the same field content of the Vasiliev's theory that accommodates each spin exactly once.

Anomalous Photofragmentation of Fullerene Doped in Silica Aerogel-Enhanced Formation of Odd-Numbered ``Fullerene'' Fragments  

NASA Astrophysics Data System (ADS)

Photofragmentation of fullerene-doped silica aerogels has been investigated by the excimer laser ablation reflectron time-of-flight mass spectrometric technique. Great enhancement in the formation of odd-numbered `fullerene' fragments has been observed in the negative-ion channel for the chemically doped aerogel sample. Generally, odd-numbered species C57, C55, C53 and C51 appeared in the mass spectra. Under optimal experimental conditions C55 can be even more intense than the neighbouring even-numbered carbon clusters. In contrast, for the physically-doped sample, just like pristine C60, only weak odd-numbered fragments were observed. In the positive-ion channel, the behaviour of all these samples is similar, no odd-numbered species was ever detected. A mechanism related to the interaction between the fullerene dopant and the silica aerogel host is suggested for the anomalous enhancement of the odd-numbered cluster formation. A preliminary discussion on the structures of the odd-numbered `fullerene' fragments is given.

Low-lying states in near-magic odd-odd nuclei and the effective interaction  

E-print Network

The iterative quasi-particle-random-phase approximation (QRPA) method we previously developed to accurately calculate properties of individual nuclear states is extended so that it can be applied for nuclei with odd numbers of neutrons and protons. The approach is based on the proton-neutron-QRPA (pnQRPA) and uses an iterative non-hermitian Arnoldi diagonalization method where the QRPA matrix does not have to be explicitly calculated and stored. The method is used to calculate excitation energies of proton-neutron multiplets for several nuclei. The influence of a pairing interaction in the $T=0$ channel is studied.

Rotational bands with strong magnetic dipole transitions have been observed in the doubly-odd nuclei {sup 82}Rb and {sup 84}Rb. These bands show the characteristic features of magnetic rotation. They are the first evidence of this new kind of nuclear excitation in the A{approx_equal}80 region.

Low-lying Odd-parity States of the Nucleon in Lattice QCD  

E-print Network

The world's first examination of the odd-parity nucleon spectrum at light quark masses in 2+1 flavor lattice QCD is presented. Configurations generated by the PACS-CS collaboration and made available through the ILDG are used, with the lightest pion mass at 156 MeV. A novel method for tracking the individual energy eigenstates as the quark mass changes is introduced. The success of this approach reveals the flow of the states towards the physical masses. Using the correlation matrix method, the two lowest-energy states revealed are found to be in accord with the physical spectrum of Nature.

Candidate chiral doublet bands in the odd-odd nucleus $^{126}$Cs  

E-print Network

The candidate chiral doublet bands recently observed in $^{126}$Cs have been extended to higher spins, several new linking transitions between the two partner members of the chiral doublet bands are observed, and $\\gamma$$-$intensities related to the chiral doublet bands are presented by analyzing the $\\gamma$$-$$\\gamma$ coincidence data collected earlier at the NORDBALL through the $^{116}$Cd$($$^{14}$N, 4n$)$$^{126}$Cs reaction at a beam energy of 65 MeV. The intraband $B(M1)/B(E2)$ and interband $B(M1)_{in}/B(M1)_{out}$ ratios and the energy staggering parameter, S(I), have been deduced for these doublet bands. The results are found to be consistent with the chiral interpretation for the two structures. Furthermore, the observation of chiral doublet bands in $^{126}$Cs together with those in $^{124}$Cs, $^{128}$Cs, $^{130}$Cs and $^{132}$Cs also indicates that the chiral conditions do not change rapidly with decreasing neutron number in these odd-odd Cesium isotopes.

P-odd and P-even correlations for third particles in ternary fission  

NASA Astrophysics Data System (ADS)

Within quantum-mechanical fission theory, P-odd and P-even correlations in angular distributions of products of the ternary fission of nuclei that is induced by polarized cold and thermal neutrons are investigated on the basis of a nonevaporative mechanism of third-particle emission and under the assumption that a two-humped fission barrier exists. It is shown that these correlations for third particles are induced by the analogous correlations for ternary-fission fragments, the latter being transferred to the third particle because of the kinematical conditions of third-particle emission that are associated with the charge and mass asymmetry of fragments. Optimum methods for observing the above correlations for third particles are discussed. The possibility of discovering the emission of prescission neutrons in the fission process against the background of evaporated neutrons by means of studying P-odd and P-even correlations is explored.

Tile-boundary artifact reduction using odd tile size and the low-pass first convention.  

PubMed

It is well known that tile-boundary artifacts occur in wavelet-based lossy image coding. However, until now, their cause has not been understood well. In this paper, we show that boundary artifacts are an inescapable consequence of the usual methods used to choose tile size and the type of symmetric extension employed in a wavelet-based image decomposition system. This paper presents a novel method for reducing these tile-boundary artifacts. The method employs odd tile sizes (2N + 1 samples) rather than the conventional even tile sizes (2N samples). It is shown that, for the same bit rate, an image compressed using an odd tile length low-pass first (OTLPF) convention has significantly less boundary artifacts than an image compressed using even tile sizes. The OTLPF convention can also be incorporated into the JPEG 2000 image compression algorithm using extensions defined in Part 2 of this standard. PMID:16121452

Parity-odd effects and polarization rotation in graphene  

E-print Network

We show that the presence of parity-odd terms in the conductivity (or, in other words, in the polarization tensor of Dirac quasiparticles in graphene) leads to rotation of polarization of the electromagnetic waves passing through suspended samples of graphene. Parity-odd Chern-Simons type contributions appear in external magnetic field, giving rise to a quantum Faraday effect (though other sources of parity-odd effects may also be discussed). The estimated order of the effect is well above the sensitivity limits of modern optical instruments.

Topological Blount's theorem of odd-parity superconductors  

NASA Astrophysics Data System (ADS)

Blount's theorem prohibits the existence of line nodes for odd-parity superconductors (SCs) in the presence of spin-orbit coupling (SOC). We studied the topological stability conditions of line nodes under inversion symmetry by generalizing the original statement and establishing a relation to surface zero-energy states. The topological instability of line nodes in odd-parity SCs implies the disappearance of corresponding flat zero-energy surface dispersions due to surface Rashba SOC, which provides an experimental means to distinguish line nodes in odd-parity SCs from those in other SCs.

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.

Odd systems in deformed relativistic Hartree Bogoliubov theory in continuum  

E-print Network

In order to describe the exotic nuclear structure in unstable odd-$A$ or odd-odd nuclei, the deformed relativistic Hartree Bogoliubov theory in continuum has been extended to incorporate the blocking effect due to the odd nucleon. For a microscopic and self-consistent description of pairing correlations, continuum, deformation, blocking effects, and the extended spatial density distribution in exotic nuclei, the deformed relativistic Hartree Bogoliubov equations are solved in a Woods-Saxon basis in which the radial wave functions have a proper asymptotic behavior at large $r$. The formalism and numerical details are provided. The code is checked by comparing the results with those of spherical relativistic continuum Hartree Bogoliubov theory in the nucleus $^{19}$O. The prolate deformed nucleus $^{15}$C is studied by examining the neutron levels and density distributions.

The experimentally observed $\\Delta I = 1$ doublet bands in some odd-odd nuclei are analyzed within the orthosymplectic extension of the Interacting Vector Boson Model (IVBM). A new, purely collective interpretation of these bands is given on the basis of the obtained boson-fermion dynamical symmetry of the model. It is illustrated by its application to three odd-odd nuclei from the $A\\sim 130$ region, namely $^{126}Pr$, $^{134}Pr$ and $^{132}La$. The theoretical predictions for the energy levels of the doublet bands as well as $E2$ and $M1$ transition probabilities between the states of the yrast band in the last two nuclei are compared with experiment and the results of other theoretical approaches. The obtained results reveal the applicability of the orthosymplectic extension of the IVBM.

Odd- and Even-Frequency Superconductivities Mediated by Ferromagnetic Magnons  

NASA Astrophysics Data System (ADS)

On the basis of a generalized Kondo-lattice model (i.e., spin-fermion model), we examine herein superconductivity mediated by magnetic excitations in ferromagnets. By applying the perturbation theory, we derive effective pairing interactions between conduction electrons. Pairing fluctuations are numerically calculated by fully accounting for the momentum and frequency dependences in quasi-one dimension. The results indicate that the normal state is unstable against even- and odd-frequency pairing fluctuations, depending on the temperature and model parameters. In a few cases, we obtain phase diagrams. The two-magnon exchange interaction is found to favor odd-frequency pairing at high temperatures (but below the ferromagnetic transition temperature); however, at low temperatures, triangle processes involving two magnons and one electron induce even- and odd-frequency pairings depending on the signs of the coupling constants of the Kondo interaction. Finally, we discuss the possibility of odd-frequency superconductivity as a bulk state in ferromagnetic superconductors.

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.

Diverse activities have been shown to improve children's executive functions: computerized training, noncomputerized games, aerobics, martial arts, yoga, mindfulness, and school curricula. All successful programs involve repeated practice and progressively increase the challenge to executive functions. Children with worse executive functions benefit most from these activities; thus, early executive-function training may avert widening achievement gaps later.

Low-lying T=0 states in the odd-odd N=Z nucleus 62Ga  

NASA Astrophysics Data System (ADS)

New, low-lying levels in the odd-odd, N=Z nucleus 62Ga have been identified using a sensitive technique, where in-beam ? rays from short-lived nuclei are tagged with ? decays following recoil mass identification. A comparison of the results with shell-model and IBM-4 calculations demonstrates good agreement between theory and experiment, with the majority of predicted low-lying, low-spin T=0 states now identified. There is a dramatic change in the level density at low excitation energies for the N=Z nucleus 62Ga when compared with neighbouring odd-odd Ga isotopes where, in contrast, the low-lying level structure is dominated by configurations with T=1 pairing interactions between excess neutrons. This illustrates the distinctively different aspects of nuclear structure exhibited by nuclei with N=Z.

P-odd, P-even, and T-odd asymmetries in true quaternary fission of nuclei  

NASA Astrophysics Data System (ADS)

The coefficients of P-odd, P-even, and T -odd asymmetries for a third and a fourth prescission particle emitted in the true quaternary fission of nuclei that was induced by polarized cold neutrons were studied on the basis of quantum-mechanical fission theory. By using non-evaporation (nonadiabatic) mechanisms of light-particle emission, these coefficients were compared with the analogous coefficients for prescission third particles emitted in the ternary fission of nuclei.

Enumeration of quarter-turn symmetric alternating-sign matrices of odd order  

E-print Network

It was shown by Kuperberg that the partition function of the square-ice model related to the quarter-turn symmetric alternating-sign matrices of even order is the product of two similar factors. We propose a square-ice model whose states are in bijection with the quarter-turn symmetric alternating-sign matrices of odd order, and show that the partition function of this model can be also written in a similar way. This allows to prove, in particular, the conjectures by Robbins related to the enumeration of the quarter-turn symmetric alternating-sign matrices.

Odd-spin yrast states as multiple quadrupole-phonon excitations  

NASA Astrophysics Data System (ADS)

The wavefunctions of the lowest odd spin positive parity yrast states in the IBA are shown to be nearly pure multiple quadrupole-phonon excitations even outside the three dynamical symmetries. The empirical data for collective nuclei with 30? Z?80 confirm these predictions. The quadrupole-phonon purity of the 2 1+ state can be measured from E2-branching ratios of the 3 1+ state. These data show a high correlation to the 2 1+ Q-phonon purity deduced from the E2-decay of 2 + states.

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.

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.

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

Scattering of x-rays enhanced by an electric dipole-electric quadrupole (E1-E2) event probe parity-odd atomic multipoles at the heart of many current theories of complex materials, e.g., Mott-Hubbard insulators and multiferroics. We achieve a complete decomposition of the E1-E2 scattering amplitude at spin-orbit split states in terms of atomic multipoles, albeit unfamiliar composite atomic operators built with electron position, spin and orbital variables. In consequence, one has clear insight as to the physical makeup of quantities that determine structure factors for Bragg diffraction enhanced by resonant ions that occupy sites devoid of inversion symmetry.

Iron-Based Superconductors as Odd-Parity Superconductors  

NASA Astrophysics Data System (ADS)

Parity is a fundamental quantum number used to classify a state of matter. Materials rarely possess ground states with odd parity. We show that the superconducting state in iron-based superconductors is classified as an odd-parity s-wave spin-singlet pairing state in a single trilayer FeAs/Se, the building block of the materials. In a low-energy effective model constructed on the Fe square bipartite lattice, the superconducting order parameter in this state is a combination of an s-wave normal pairing between two sublattices and an s-wave ? pairing within the sublattices. The state has a fingerprint with a real-space sign inversion between the top and bottom As/Se layers. The results suggest that iron-based superconductors are a new quantum state of matter, and the measurement of the odd parity can help to establish high-temperature superconducting mechanisms.

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.

Mechanisms of excitation of T-odd correlations for prescission gamma rays and structure of these correlations  

NASA Astrophysics Data System (ADS)

Conditions for the appearance and observation of prescission gamma rays emitted by a fissioning nucleus prior to its separation into fission fragments were investigated within quantum-mechanical fission theory. It is shown that these conditions are realizable in the gamma decay of isovector electric giant dipole resonances in a fissile nucleus that are excited because of nonadiabaticity of the collective deformation motion of the nucleus at the ultimate stages of its prefission evolution. Angular and energy distributions of prescission gamma rays emitted by unpolarized fissioning nuclei are analyzed. Features of T-odd correlations in angular distributions of gamma rays arising in the fission of unpolarized target nuclei that is induced by polarized cold neutrons are investigated, and it is shown that these correlations are similar in nature to T-odd ROT correlations discovered earlier for alpha particles emitted in the ternary fission of nuclei.

Properties of the ?h 9/2 ? ?i 13/2 band in odd-odd 188Au

The Antarctic ozone minimum - Relationship to odd nitrogen, odd chlorine, the final warming, and the 11-year solar cycle  

NASA Technical Reports Server (NTRS)

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.

Fission fragment angular momentum in ODD-Z fissioning systems

From the independent isomeric yield ratios, fragment angular momenta (Jrms) have been deduced using spin-dependent statistical model analysis. Comparison of these data with the literature data for even-Z fissioning systems shows the following important features: (i) Angular momenta for fragments with spherical 82n shell and even-Z products are lower compared to the fragments with out the 82n shell and odd-Z products indicating the effect of nuclear structure. (ii) Angular momentum of even-Z products in all the fissioning systems are comparable where as for odd-Z products it is slightly higher in the odd-Z fissioning systems than in the adjacent even-Z fissioning systems. This indicates the role of single particle on fragment angular momentum in odd-Z fissioning systems.

CP-odd Phase Correlations and Electric Dipole Moments  

E-print Network

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 (CMSSM), the CP-odd invariant related to the soft trilinear A-phase at the GUT scale, theta_A, induces non-trivial 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_A. We perform a detailed analysis of the EDM constraints within the CMSSM, 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.

Requiring the total {delta} operator to be nilpotent leads to a differential condition for {nu}, which is integrable. It turns out that the odd function {nu} is not an independent geometric object but is instead completely specified by the antisymplectic structure E and the density {rho}. The main impact of introducing the {nu} term is that it makes compatibility relations between E and {rho} obsolete. We give a geometric interpretation of {nu} as (minus (1/8) times) the odd scalar curvature of an arbitrary antisymplectic, torsion-free, and {rho}-compatible connection. We show that the total {delta} operator is a {rho}-dressed version of Khudaverdian's {delta}{sub E} operator, which takes semidensities to semidensities. We also show that the construction generalizes to the situation where {rho} is replaced by a nonflat line bundle connection F. This generalization is implemented by breaking the nilpotency of {delta} with an arbitrary Grassmann-even second-order operator source.

The distribution of odd nitrogen in the lower stratosphere and possible perturbations caused by stratospheric air transport  

NASA Technical Reports Server (NTRS)

In the lower stratosphere a significant production of odd nitrogen results from the reaction N2O + O(D-1) yields 2NO. Since the transport is relatively slow, odd nitrogen builds up with a maximum mixing ratio of 2 x 10 to the minus 8th power at 30 Km. Profiles of odd nitrogen, for different latitudes, winter and summer, are computed from one-dimensional transport models. Variations with latitude are small. Horizontal transport is therefore not believed to alter our results significantly. In order to evaluate the effect of odd nitrogen upon the ozone layer, NO(x) profiles are calculated. OH is here a key component, since it converts NO2 to HNO3. In the region where ozone is determined by chemistry rather than by transport (above 25 km), NO2 is found to be relatively abundant. The effect of stratospheric transport on the NO(x) distribution is shown to depend critically upon the height of emission. The effect increases by a factor of 5 or more for a change of flight level from 18 km to 23 km. This strong dependence should be duely considered when future stratospheric transport is discussed.

Proposed search for T-odd, P-even interactions in spectra of chaotic atoms with frequency combs  

NASA Astrophysics Data System (ADS)

Violation of fundamental symmetries in atoms has been the subject of intense experimental and theoretical interest. P-odd, T-even transitions have been observed and are in excellent agreement with electroweak theory. Electron EDM searches have placed bounds on T-odd, P-odd interactions, constraining proposed extensions to the Standard Model. In this work we propose a search for T-odd, P-even (TOPE) interactions in atoms, which have thus far received little attention. We consider open-shell atoms (such as the rare earths) which have dense, chaotic excitation spectra with strong level repulsion. The strength of the level repulsion depends on the underlying symmetries of the atomic Hamiltonian. TOPE interactions lead to increased level repulsion. We will demonstrate how a statistical analysis of many chaotic spectra can determine the strength of level repulsion; in particular, the variance of the number of levels in an energy range has been shown to be a useful measure. We estimate that, using frequency comb spectroscopy, a sufficient number of chaotic levels could be measured to match or exceed the current experimental bounds on TOPE interactions.

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.

Investigation of odd-order nonlinear susceptibilities in atomic vapors  

SciTech Connect

We theoretically deduce the macroscopic symmetry constraints for arbitrary odd-order nonlinear susceptibilities in homogeneous media including atomic vapors for the first time. After theoretically calculating the expressions using a semiclassical method, we demonstrate that the expressions for third- and fifth-order nonlinear susceptibilities for undressed and dressed four- and six-wave mixing (FWM and SWM) in atomic vapors satisfy the macroscopic symmetry constraints. We experimentally demonstrate consistence between the macroscopic symmetry constraints and the semiclassical expressions for atomic vapors by observing polarization control of FWM and SWM processes. The experimental results are in reasonable agreement with our theoretical calculations. -- Highlights: •The macroscopic symmetry constraints are deduced for homogeneous media including atomic vapors. •We demonstrate that odd-order nonlinear susceptibilities satisfy the constraints. •We experimentally demonstrate the deduction in part.

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.

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.

Odd-bit symmetric QASK. [quadrature amplitude shift keyed signals  

NASA Technical Reports Server (NTRS)

Multiple-amplitude and phase-shift-keyed (MAPSK) signal set selection is influenced by factors such as average and/or peak signal-to-noise ratio for a given error probability, dynamic range of signal amplitudes, simplicity of generation and detection, and number of bit errors per adjacent symbol error. This paper compares two possible quadrature-amplitude-shift-keyed (QASK) signal sets for the case where the number of bits per symbol is odd (for the even-bit case, the square array is the only viable QASK choice). The symmetric QASK version out-performs the rectangular QASK set at a very modest implementation penalty. This permits symmetric QASK to be considered in future odd-bit system studies.

Predator fitness increases with selectivity for odd prey.  

PubMed

The fundamental currency of normative models of animal decision making is Darwinian fitness. In foraging ecology, empirical studies typically assess foraging strategies by recording energy intake rates rather than realized reproductive performance. This study provides a rare empirical link, in a vertebrate predator-prey system, between a predator's foraging behavior and direct measures of its reproductive fitness. Goshawks Accipiter gentilis selectively kill rare color variants of their principal prey, the feral pigeon Columba livia, presumably because targeting odd-looking birds in large uniform flocks helps them overcome confusion effects and enhances attack success. Reproductive performance of individual hawks increases significantly with their selectivity for odd-colored pigeons, even after controlling for confounding age effects. Older hawks exhibit more pronounced dietary preferences, suggesting that hunting performance improves with experience. Intriguingly, although negative frequency-dependent predation by hawks exerts strong selection against rare pigeon phenotypes, pigeon color polymorphism is maintained through negative assortative mating.

(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.

PubMed

To obtain a more complete understanding of the evolutionary history of the leaf-eating monkeys we have examined the mitochondrial genome sequence of two African and six Asian colobines. Although taxonomists have proposed grouping the "odd-nosed" colobines (proboscis monkey, douc langur, and the snub-nosed monkey) together, phylogenetic support for such a clade has not been tested using molecular data. Phylogenetic analyses using parsimony, maximum likelihood, and Bayesian methods support a monophyletic clade of odd-nosed colobines consisting of Nasalis, Pygathrix, and Rhinopithecus, with tentative support for Nasalis occupying a basal position within this clade. The African and Asian colobine lineages are inferred to have diverged by 10.8 million years ago (mya or Ma). Within the Asian colobines the odd-nosed clade began to diversify by 6.7 Ma. These results augment our understanding of colobine evolution, particularly the nature and timing of the colobine expansion into Asia. This phylogenetic information will aid those developing conservation strategies for these highly endangered, diverse, and unique primates. PMID:16500120

Change of shell structure and magnetic moments of odd-N deformed nuclei towards neutron drip line  

E-print Network

Examples of the change of neutron shell-structure in both weakly-bound and resonant neutron one-particle levels in nuclei towards the neutron drip line are exhibited. It is shown that the shell-structure change due to the weak binding may lead to the deformation of those nuclei with the neutron numbers $N \\approx$ 8, 20, 28 and 40, which are known to be magic numbers in stable nuclei. Nuclei in the "island of inversion" are most easily and in a simple manner understood in terms of deformation. As an example of spectroscopic properties other than single-particle energies, magnetic moments of some weakly-bound possibly deformed odd-N nuclei with neutron numbers close to those traditional magic numbers are given, which are calculated using the wave function of the last odd particle in deformed Woods-Saxon potentials.

Measurement of lifetimes and tensor polarizabilities of odd-parity states of atomic samarium  

SciTech Connect

A systematic measurement of the lifetimes and tensor polarizabilities of the lowest-lying odd-parity levels of Sm I was performed. The lifetimes were measured by detecting time-resolved fluorescence following pulsed-laser excitation of atoms in an atomic beam; polarizabilities were measured employing the method of Stark-induced quantum beats. An analysis of the data is undertaken to find the best even-parity candidate states for an atomic electric dipole moment (EDM) measurement. For the most favorable candidate state ({sup 7}G{sub 1}), the electron EDM enhancement factor is evaluated to be in the range {vert_bar}R{vert_bar}{approx}100{endash}3800. Critical analysis of the present data along with earlier results in Sm shows the necessity of a term reassignment for several odd-parity states. This term reassignment is also used in an estimate of the parity-nonconserving {sup 7}F{sub 0}{r_arrow}{sup 7}G{sub 1} amplitude. {copyright} {ital 1999} {ital The American Physical Society}

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.

P and T odd effects in deuteron in the Reid potential  

E-print Network

The $P$ and $T$ odd deuteron multipoles are calculated in the Reid nucleon-nucleon potential in the chiral limit $m_{\\pi}\\to 0$. The contact current generated by the $\\pi$-meson exchange does not contribute to the anapole moment. The contact current generated by the vector meson exchange is negligible in comparison with other contributions of vector mesons. The result for the deuteron electric dipole moment is of great interest because of the experiment on its measurement discussed in Brookhaven. The deuteron photodisintegration cross section asymmetry at the threshold is also calculated. It is shown that its value strongly depends on the tensor forces and d-wave contribution to the deuteron wave function.

The phenomenon of time-reversal violating generation of static magnetic and electric fields is a basis of a new method for measurement of the electron EDM and Todd P-odd constants of electron interaction with a nucleon beyond Standard Model  

Microsoft Academic Search

It is shown that in the experiments for search of EDM of an electron (atom, molecule) the T-odd magnetic moment induced by an electric field and the T-odd electric dipole moment induced by a magnetic field will be also measured. It is discussed how to distinguish these contributions.

Refuting the odd number limitation of time-delayed feedback control  

E-print Network

We refute an often invoked theorem which claims that a periodic orbit with an odd number of real Floquet multipliers greater than unity can never be stabilized by time-delayed feedback control in the form proposed by Pyragas. Using a generic normal form, we demonstrate that the unstable periodic orbit generated by a subcritical Hopf bifurcation, which has a single real unstable Floquet multiplier, can in fact be stabilized. We derive explicit analytical conditions for the control matrix in terms of the amplitude and the phase of the feedback control gain, and present a numerical example. Our results are of relevance for a wide range of systems in physics, chemistry, technology,and life sciences, where subcritical Hopf bifurcations occur.

Chiral Odd Generalized Parton Distributions in Impact Parameter Space  

E-print Network

We investigate the chiral odd generalized parton distributions (GPDs) for the quantum fluctuations of an electron in QED. The light-front wave function (LFWF) of this system gives a template for the quark spin-one diquark structure of the valence LFWF of the proton. We express the GPDs in terms of overlaps of LFWFs and obtain their representation in impact parameter space when the momentum transfer is purely transverse. We show the spin-orbit correlation effect of the two-particle LFWF as well as the correlation between the constituent spin and the transverse spin of the target.

Odd-parity perturbations of self-similar Vaidya spacetime  

E-print Network

We carry out an analytic study of odd-parity perturbations of the self-similar Vaidya space-times that admit a naked singularity. It is found that an initially finite perturbation remains finite at the Cauchy horizon. This holds not only for the gauge invariant metric and matter perturbation, but also for all the gauge invariant perturbed Weyl curvature scalars, including the gravitational radiation scalars. In each case, `finiteness' refers to Sobolev norms of scalar quantities on naturally occurring spacelike hypersurfaces, as well as pointwise values of these quantities.

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.

On doubly robust estimation in a semiparametric odds ratio model  

PubMed Central

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

Prospective candidates for the EDM experiments of new type: calculations of enhancement of P,T-odd effects in HI+ and liquid Xe

The search for the P,T-parity non-conservation (PNC) effects is of fundamental importance in physics. Experiments are performed on T1F and YbF, and are prepared on PbO and HgH molecules. Recently some new approaches were suggested, such as the search for P,T-odd effects in liquid xenon and on HI+ molecular ion. For preparation and interpretation of these experiments high-precision calculations of the electronic structure are required. Recently developed theoretical methods allow one to analyze the atomic-molecular systems from the point of enhancement of P,T-odd effects and recommend such or another system as a prospective candidate. We calculated enhancement factor for electron EDM in the ground state of HI+ molecular ion, required for experiment of new type on electron EDM search. The results of calculations of P,T-odd effects in liquid xenon are also discussed.

Beyond Mean-Field Calculations for Odd-Mass Nuclei  

NASA Astrophysics Data System (ADS)

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 Mg25 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.

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-even staggering in the neutron-proton interaction and nuclear mass models  

NASA Astrophysics Data System (ADS)

In this paper we study odd-even staggering of the empirical neutron-proton interaction between the last neutron and the last proton, denoted as ? V1 n -1 p , and its consequence in the Garvey-Kelson mass relations (GKs) and nuclear mass models. The root-mean-squared deviations of predicted masses respectively for even-A and odd-A nuclei by using two combinatorial GKs suggest a large odd-even staggering of ? V1 n -1 p between even-odd and odd-even nuclei, while the odd-even difference of ? V1 n -1 p between even-even and odd-odd nuclei is much smaller. The contribution of the odd-even staggering of ? V1 n -1 p between even-A and odd-A nuclei in deviations of theoretical ? V1 n -1 p values of the Duflo-Zuker model and the improved Weizs a ?cker -Skyrme model are well represented by an isospin-dependent term. The consideration of this odd-even staggering improves our description of binding energies and one-neutron separation energies in both the Duflo-Zuker model and the improved Weizs a ?cker -Skyrme model.

The ability of single-chain surfactants to emulsify an aqueous-based liquid crystal oscillates with odd-even parity of alkyl-chain length.  

PubMed

The physical properties of many organic molecules often oscillate when the number of carbons in their aliphatic chains changes from odd to even. This odd-even effect for single-chain surfactants in solution is rarely observed. Here, we report the ability of single-chain surfactants to emulsify a class of non-amphiphilic organic salts, disodium cromoglycate (5'DSCG) oscillates as a function of the odd or even number of the aliphatic carbons. This system provides a water-in-oil-in-water emulsion, in which aqueous droplets of 5'DSCG in liquid crystal phases are coated with single-chain surfactants in a bulk carrying aqueous solution. For both surfactants of [Formula: see text] and CH3(CH2)nCOO(-)Na(+), the ability to emulsify 5'DSCG molecules in water is stronger for surfactants with an odd number of sp(3)-hybridized carbon atoms in the aliphatic chains than those with an even number. This observed odd-even effect is consistent with the notion that conventional micelles possess a core of randomly arranged surfactant hydrocarbon tails. However, this water-in-oil-in-water resembles a vesicle system in which the surfactants assemble in a highly ordered structure that separates two aqueous systems. These new self-assembled phases have potential application in the formulation and design of new organic soft materials. PMID:24144379

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

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.

Piezoelectricity of the ice nanotube with odd side faces  

NASA Astrophysics Data System (ADS)

The molecular dynamics (MD) simulations have been utilized to investigate the strain effect on the polarization distribution and piezoelectric coefficient of the ice nanotube (ice-NT) with odd side faces. It is found that the polarization of the system increases under the compressive strain, and decreases with the tensile strain. The piezoelectric coefficient is about 1.3 C/m 2 for a single <5, 0> ice-NT with its diameter of 4.34 Å, which is superior to BaTiO 3 nanowire, the ferroelectricity of the latter with the same diameter has been vanished owning to the depolarization effect. We have also considered the axial strain energy under the different strains, and found that most of the strain energy in the compressive process seems larger than that of the stretching case.

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.

Completely new spectrocopic information has been obtained. The yrast level structure is established up to spin (19[sup +]) and some information on [gamma] transitions from higher-lying levels is also obtained. Two new isomers [ital T][sub 1/2]=174(20) ns and [ital T][sub 1/2]=11(2) ns were found. Configuration assignments for the low-lying levels are discussed. Information on residual proton-neutron interactions is extracted.

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.

Using the quasiparticle phonon nuclear model (QPNM) and taking into account the spin-spin interaction, the effects of the spin polarization on spin gyromagnetic factors (gs) as well as the intrinsic magnetic moments (gK) of the deformed odd neutron 155-165Dy isotopes were studied. The calculated values of gs and gK are in fair agreement with the experiment as well as with other microscopic calculations. Our calculations indicated that because of the core polarization, the gs factors of the nucleons in the nucleus reduce noticeably from its free nucleon value and the spin-spin interactions play an important role in the explanation of the quenching of the gs factors. A very good reproduction of the phenomenological quenching of gs factor from its free values (gs eff = 0.6-0.7gs free) is obtained for 155-165Dy.

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.

Emergent Odd-Frequency Superconducting Order Parameter near Boundaries in Unconventional Superconductors  

NASA Astrophysics Data System (ADS)

It was previously suggested that an odd-frequency pair amplitude exists in the vicinity of boundaries in unconventional superconductors. We develop this idea and quest for a novel superconducting order parameter with an odd-frequency dependence. For this purpose, we focus on p-wave superconductors and extend the quasi-classical theory to include the odd-frequency dependence in the order parameter. Both of the frequency and spatial dependences of the order parameter are determined self-consistently. Under a finite electron--phonon interaction, it is found that an odd-frequency order parameter is stabilized near the boundary and coexists with the even-frequency one. By analyzing the induced odd-frequency pair amplitude in terms of the superconducting quasi-particle wavefunction, it is found that the mid-gap bound state generates the emergent odd-frequency order parameter.

Direct {T}-VIOLATION Measurements and {T}-ODD Effects in Decay Experiments  

NASA Astrophysics Data System (ADS)

Motivated by the recent experimental announcements for direct measurements of time-reversal non-invariance in the neutral kaon system, we make a comparative discussion of the CPLEAR and KTeV measurements. The most suitable way to consistently incorporate the mixing, the time evolution and the decays of kaons, is to describe the neutral kaon system as a system with a non-Hermitean Hamiltonian. In this framework, the physical (decaying) incoming and outgoing states are distinct and belong to dual spaces. Moreover, since they are eigenstates of the full Hamiltonian, they never oscillate. This is directly manifest in the orthogonality conditions of the physical states, which entirely determine the evolution of the kaon system. Along these lines we conclude: CPLEAR studies K0-bar {K}0 oscillations, a process where initial and final states can be reversed, the CPLEAR asymmetry being an effect directly related to the definition of time-reversal. Conclusively, CPLEAR provides a direct measurement of {T}-violation without any assumption either on unitarity or on {CPT}-invariance. The KTeV experiment studies in particular the process KL ? ?+?-e+e-, where they measure a {T}-odd effect. However, using unitarity together with estimates of the final state interactions, it should be possible to determine whether this effect can be identified with a genuine {T}-reversal violation.

We have studied odd-even nuclear mass staggering with the Skyrme-Hartree-Fock-Bogoliubov theory by employing isoscalar and isovector contact pairing interactions. By reproducing the empirical odd-even mass differences of the Sn isotopic chain, the strengths of pairing interactions are determined. The optimal strengths adjusted in this work can give better description of odd-even mass differences than that fitted by reproducing the experimental neutron pairing gap of $^{120}$Sn.

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.

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).

Virial series for fluids of hard hyperspheres in odd dimensions  

E-print Network

A recently derived method [R. D. Rohrmann and A. Santos, Phys. Rev. E. {\\bf 76}, 051202 (2007)] to obtain the exact solution of the Percus-Yevick equation for a fluid of hard spheres in (odd) $d$ dimensions is used to investigate the convergence properties of the resulting virial series. This is done both for the virial and compressibility routes, in which the virial coefficients $B_j$ are expressed in terms of the solution of a set of $(d-1)/2$ coupled algebraic equations which become nonlinear for $d \\geq 5$. Results have been derived up to $d=13$. A confirmation of the alternating character of the series for $d\\geq 5$, due to the existence of a branch point on the negative real axis, is found and the radius of convergence is explicitly determined for each dimension. The resulting scaled density per dimension $2 \\eta^{1/d}$, where $\\eta$ is the packing fraction, is wholly consistent with the limiting value of 1 for $d \\to \\infty$. Finally, the values for $B_j$ predicted by the virial and compressibility routes in the Percus-Yevick approximation are compared with the known exact values [N. Clisby and B. M. McCoy, J. Stat.

Airborne measurements of total reactive odd nitrogen (NO(y))  

NASA Technical Reports Server (NTRS)

Airborne total reactive odd nitrogen measurements were made during August and September 1986 over the continental United States and off the west coast over the Pacific Ocean during NASA's Global Tropospheric Experiment/Chemical Instrumentation Test and Evaluation 2 program. Measurements were made in the marine and continental boundary layer and the free troposphere up to 6.1 km altitude. NO(y) mixing ratios between 24 pptv and more than 1 ppbv were found, with median values of 101 pptv in the marine boundary layer, 298 pptv in the marine free troposphere, and 288 pptv in the continental free troposphere, respectively. The marine troposphere exhibited layered structure which was also seen in the simultaneously measured ozone mixing ratio and dew point temperature. The averaged vertical NO(y) profile over the ocean does not show a distinct gradient. The NO(y) mixing ratio over the continent decreases with increasing altitude. The latter is consistent with our understanding that the continents are the major source region for these gases.

Explicit energy expansion for general odd degree polynomial potentials  

E-print Network

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.

No evidence for the expected 1{sup +} ground-state was found in the {sup 144}Ho decay data. The proton emission from {sup 146}Tm was restudied and the spin and parity values of I{sup {pi}} = 10{sup +} and 5{sup -} were established for {sup 146m}Tm and {sup 146gs}Tm, respectively. The interpretation of the observed decay properties and structure of the proton-emitting states was made by accounting for deformation and proton and neutron coupling to the core excitations.

Estimating standardized mortality odds ratios with national mortality followback data.  

PubMed

Proportionate mortality analyses are often used to study cause-specific mortality when population denominators are not available. The purpose of this paper is to present an extension of published proportionate mortality ratio logistic regression methods used to analyze such data. This paper describes methods used to estimate standardized mortality odds ratios (SMORs) with numerator data and the problems encountered when external standard rates are not available for all strata of interest. This paper focuses on the case where one has representative mortality followback data. These data are based on a large, representative sample of deaths from a defined population for whom numerous covariates about the decedents are collected from surviving family members. With these data, one may use logistic regression methods to generate fully standardized estimates of risk, SMORs, with numerator data. It is also possible to generate SMORs that allow for effect modification. Mortality followback data are also a more flexible data source from which one may generate substitutes for external standard mortality rate ratios to be used with previously developed SMOR methods. An application of the methods is provided using logistic regression. PMID:7888446

A zonally averaged two-dimensional model for chemical species in the atmosphere (Olaguer et al., 1990), with coupled dynamics, radiation transfer, and chemistry, is used to study the present-day atmospheric ozone, odd nitrogen, chlorine, other species. The model utilizes all zonally averaged physical equations of momentum, energy, and mass and determines self-consistently the advective and diffusive tranasport parameters from the temperature specific to the period of observation. A comparison of the model results with observations showed good agreement.

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.

A marker strongly associated with outcome (or disease) is often assumed to be effective for classifying persons according to their current or future outcome. However, for this assumption to be true, the associated odds ratio must be of a magnitude rarely seen in epidemiologic studies.

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.

Data mining in bone marrow transplant records to identify patients with high odds of survival.  

PubMed

Patients undergoing a bone marrow stem cell transplant (BMT) face various risk factors. Analyzing data from past transplants could enhance the understanding of the factors influencing success. Records up to 120 measurements per transplant procedure from 1751 patients undergoing BMT were collected (Shariati Hospital). Collaborative filtering techniques allowed the processing of highly sparse records with 22.3% missing values. Ten-fold cross-validation was used to evaluate the performance of various classification algorithms trained on predicting the survival status. Modest accuracy levels were obtained in predicting the survival status (AUC = 0.69). More importantly, however, operations that had the highest chances of success were shown to be identifiable with high accuracy, e.g., 92% or 97% when identifying 74 or 31 recipients, respectively. Identifying the patients with the highest chances of survival has direct application in the prioritization of resources and in donor matching. For patients where high-confidence prediction is not achieved, assigning a probability to their survival odds has potential applications in probabilistic decision support systems and in combination with other sources of information.

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

NASA Astrophysics Data System (ADS)

Improvement 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.

Odd-mode surface plasmon polaritons supported by complementary plasmonic metamaterial.  

PubMed

Surface plasmon polaritons (SPPs), either on metal-dielectric interfaces in optical frequencies or on structured metal surfaces in the lower frequencies, are dominantly even modes. Here we discover dominant odd-mode SPPs on a complementary plasmonic metamaterial, which is constructed by complementary symmetric grooves. We show that the fundamental SPP mode on such a plasmonic metamaterial is a tightly confined odd mode, whose dispersion curve can be tuned by the shape of groove. According to the electric field distributions of odd-mode SPPs, we propose a high-efficiency transducer using asymmetric coplanar waveguide and slot line to excite the odd-mode SPPs. Numerical simulations and experimental results validate the high-efficiency excitation and excellent propagation performance of odd-mode SPPs on the complementary plasmonic waveguides in the microwave frequencies.

Enhanced interferometry using squeezed thermal states and even or odd states  

E-print Network

We derive a general expression of the quantum Fisher information for a Mach-Zehnder interferometer, with the port inputs of an \\emph{arbitrary} pure state and a squeezed thermal state. We find that the standard quantum limit can be beaten, when even or odd states are applied to the pure-state port. In particular, when the squeezed thermal state becomes a thermal state, all the even or odd states have the same quantum Fisher information for given photon numbers. For a squeezed thermal state, optimal even or odd states are needed to approach the Heisenberg limit. As examples, we consider several common even or odd states: Fock states, even or odd coherent states, squeezed vacuum states, and single-photon-subtracted squeezed vacuum states. We also demonstrate that super-precision can be realized by implementing the parity measurement for these states.

Odd-even effect in heavy-ion collisions at intermediate energies  

SciTech Connect

Heavy-ion collisions at intermediate energies are studied by the isospin-dependent quantum molecular dynamics model in the company of the GEMINI model. The isospin-dependent quantum molecular dynamics model is applied to describe the violent stage of the collisions, while the GEMINI model is applied to simulate the decays of the prefragments. The present study mainly focuses on the odd-even effect in the yields of the final fragments. We find that the odd-even effect appears in the deexcitation process of the excited prefragments, and is affected by the excitation energies and the isotope distributions of the prefragments. Both the projectile-isospin-dependent odd-even effect in the region of -4{<=}T{sub Z}{<=}1 and the role of the symmetry energy on the odd-even effect are studied. We find that the odd-even effect depends sensitively on the symmetry energy.

An apparent 'even-odd' cycle distribution in Mt. Wilson 'numbers of spots' data  

NASA Technical Reports Server (NTRS)

Mt. Wilson 'numbers of spots' data (Howard et al., 1984) appear to be distributed according to 'even-odd' cycle numbering. Linear fits of annual 'numbers of spots' versus annual sunspot number for even- and odd-numbered cycles have slopes which are statistically different at the 5 percent level of significance. The existence of an 'even-odd' split in Mt. Wilson 'numbers of spots' data may be due either to a real difference in even- and odd-numbered cycles on the sun or to a difference in weather at Mt. Wilson during even- and odd-numbered cycles, or both. For cycle 22, an even-numbered cycle, the peak 'numbers of spots' is estimated to be near 2600.

Interference of fission amplitudes of neutron resonances and T-odd asymmetry for various prescission third particles in the ternary fission of nuclei  

SciTech Connect

Differential cross sections for reactions of the true ternary fission of nuclei that was induced by cold polarized neutrons were constructed with allowance of the effect that Coriolis interaction and the interference between fission amplitudes of neutron resonances excited in fissile nuclei upon incidentneutron capture by target nuclei exerted on angular distributions of prescission third particles (alpha particles, neutrons, or photons). It is shown that T -odd TRI- and ROT-type asymmetries for prescission alpha particles are associated with, respectively, the odd and even components of the Coriolis interaction-perturbed amplitude of angular distributions of particles belonging to the types indicated above. These asymmetries have angular distributions differing from each other and stemming from a nontrivial dependence of these components on the neutron-resonance spins J{sub s} and their projections K{sub s} onto the symmetry axis of the nucleus involved. It is shown that angular distributions of prescission photons and neutrons from reactions of the ternary fission of nuclei that is induced by cold polarized neutrons are determined by the effect of Coriolis forces exclusively. Therefore, the emerging T-odd asymmetries have a character of a ROT-type asymmetry and are universal for all target nuclei.

The decoherence of the quantum excitation of even/odd coherent states in a photon-loss channel  

NASA Astrophysics Data System (ADS)

In this paper, the decoherence of the quantum excitation (the photon-added case) of even/odd coherent states, ({{({{\\hat{a}}^{\\dagger }})}^{m}}\\mid {{\\alpha }_{+/- }}\\rangle ) in a photon-loss channel is studied via the evaluation of the negative part of the Wigner quasi-distribution function in terms of the rescaled time (\\gamma t). We first obtain the explicit form of the time-dependent Wigner functions of the states considered, for arbitrary values of the photon excitations. To achieve this purpose, an equivalent Fokker-Planck-like equation which describes the time evolution of the Wigner function in the framework of the standard master equation of the density matrix is used. Then, by analyzing the time variation of the corresponding Wigner functions, the loss of the nonclassicality behavior and, hence, the decay of the negative part of the Wigner functions as a result of decoherence are clearly shown. In particular, we derive the threshold value of the rescaled time for single-photon-added even and odd coherent states; through this it is observed that the associated Wigner functions become positive whenever the rescaled time exceeds that value, i.e., the decoherence has become complete. By virtue of numerical calculations, it is also illustrated that the negative volume of the corresponding Wigner functions decreases with increasing time. In addition, the states with larger values of the excitation number m generally (but not absolutely always) possess smaller values of the rescaled threshold time.

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.

The neutron and proton odd-even mass differences are systematically studied with Hartree-Fock+BCS (HFBCS) calculations with Skyrme interactions and an isospin dependent contact pairing interaction. The strength of pairing interactions is determined to reproduce empirical odd-even mass differences in a wide region of mass table. By using the optimal parameter, we perform global HF+BCS calculations of nuclei and compare with experimental data. The importance of isospin dependence of the pairing interaction is singled out for odd-even mass differences in medium and heavy isotopes. The proton and neutron radii are studied systematically by using the same model.

An 'unconditional-like' structure for the conditional estimator of odds ratio from 2 x 2 tables.  

PubMed

In the estimation of the odds ratio (OR), the conditional maximum-likelihood estimate (cMLE) is preferred to the more readily computed unconditional one (uMLE). However, the exact cMLE does not have a closed form to help divine it from the uMLE or to understand in what circumstances the difference between the two is appreciable. Here, the cMLE is shown to have the same 'ratio of cross-products' structure as its unconditional counterpart, but with two of the cell frequencies augmented, so as to shrink the unconditional estimator towards unity. The augmentation involves a factor, similar to the finite population correction, derived from the minimum of the marginal totals. PMID:16544810

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

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.

Spin-orbit interaction in final state as possible reason for T-odd correlation in ternary fission  

E-print Network

A model for ternary fission is discussed in which a third particle (alpha-particle) is emitted due to non-adiabatic change of the nuclear potential at neck rapture. An expression for energy and angular distribution of alpha-particles is proposed. It is shown that an interaction between spin of fissioning system and orbital momentum of alpha-particle (spin-orbit interaction in the final state) results in recently observed asymmetry of alpha-particle emission, which can be formally related to T-odd correlation. No strong dependence of the asymmetry on the angle of alpha-particle emission with respect to the fission axis is predicted by the model in accordance with the experimental data.

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.

NASA Astrophysics Data System (ADS)

We report the mass spectrometric investigation on fullerence derivatives C60CH2, C60RH, C60R2(R= C6H5CO-) and C60On under the 308 nm laser ablation. In the negative ion mass spectra of C60CH2 C60R2, and C60On, odd-numbered clusters C57-, C55-, C53-, C51- are observed clearly in addition to the even-numbered fullerene fragment ions, while for the monoadduct C60RH, odd-numbered species can not be detected. In the positive ion channel, the fragmentation patterns of the three derivatives are similar. A mechanism related to the structural characteristics of the derivatives is supposed for the odd-numbered cluster formation. The 3-membered ring formed on the C60 cage is thought of to play a vital role for the formation of odd-numbered carbon clusters.

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.

A model for phonon coupling contributions to electromagnetic moments of odd spherical nuclei  

NASA Astrophysics Data System (ADS)

Within the Theory of Finite Fermi Systems (TFFS), a model is developed to describe Phonon Coupling (PC) effects in odd magic and semi-magic nuclei. It is based on the perturbation theory in g^2_L , where gL is the vertex of the L-phonon creation. Among all g^2_L diagrams the set is separated which depends significantly on the nucleus under consideration and the state ? of the odd nucleon. An ansatz is proposed to take into account the phonon tadpole diagram which ensures the total angular-momentum conservation. Calculations are carried out for three odd-proton chains, the odd Tl, In and Sb ones. Different PC corrections strongly cancel each other. In the result, the total PC correction to magnetic moments in magic nuclei is, as a rule, negligible. In the non-magic nuclei considered it is noticeable and improves the agreement with data.

Misinterpretation of statistical distance in security of quantum key distribution shown by simulation  

NASA Astrophysics Data System (ADS)

This study will test an interpretation in quantum key distribution (QKD) that trace distance between the distributed quantum state and the ideal mixed state is a maximum failure probability of the protocol. Around 2004, this interpretation was proposed and standardized to satisfy both of the key uniformity in the context of universal composability and operational meaning of the failure probability of the key extraction. However, this proposal has not been verified concretely yet for many years while H. P. Yuen and O. Hirota have thrown doubt on this interpretation since 2009. To ascertain this interpretation, a physical random number generator was employed to evaluate key uniformity in QKD. In this way, we calculated statistical distance which correspond to trace distance in quantum theory after a quantum measurement is done, then we compared it with the failure probability whether universal composability was obtained. As a result, the degree of statistical distance of the probability distribution of the physical random numbers and the ideal uniformity was very large. It is also explained why trace distance is not suitable to guarantee the security in QKD from the view point of quantum binary decision theory.

We consider gluon rescattering as a mechanism to calculate a leading twist T-odd pion fragmentation function, a favored candidate for filtering the transversity properties of the nucleon. We evaluate the single spin azimuthal asymmetry for a transversely polarized target in semi-inclusive deep inelastic scattering (for HERMES kinematics). Additionally, we calculate the double T-odd cos 2?> asymmetry in this framework.

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.

Hepatic copper distribution in primary biliary cirrhosis shown by the scanning proton microprobe.  

PubMed Central

A number of conditions are associated with abnormalities of trace metal handling by the liver. We report the application of the Oxford scanning proton microprobe to the analysis of hepatic copper in one such condition, primary biliary cirrhosis. The scanning proton microprobe analyses conventional tissue sections (5-10 micron thickness) and produces simultaneous elemental distribution maps of biologically relevant elements with a spatial resolution of 1 micron and a detection limit better than 1 ppm. We have confirmed the localisation of excess copper to periportal areas and suggest that such accumulation is confined to a proportion of periportal hepatocytes. We have also shown a close spatial correlation between regions of copper accumulation and areas of high sulphur concentration. The copper to sulphur ratio in these areas is consistent with their identity as aggregates of copper loaded metallothionein, and the scanning proton microprobe was further able to show that the aggregates contain less than 30 ppm zinc.

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).

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

One influenza virus particle packages eight unique viral RNAs as shown by FISH analysis  

PubMed Central

Influenza A virus possesses a segmented genome of eight negative-sense, single-stranded RNAs. The eight segments have been shown to be represented in approximately equal molar ratios in a virus population; however, the exact copy number of each viral RNA segment per individual virus particles has not been determined. We have established an experimental approach based on multicolor single-molecule fluorescent in situ hybridization (FISH) to study the composition of viral RNAs at single-virus particle resolution. Colocalization analysis showed that a high percentage of virus particles package all eight different segments of viral RNAs. To determine the copy number of each RNA segment within individual virus particles, we measured the photobleaching steps of individual virus particles hybridized with fluorescent probes targeting a specific viral RNA. By comparing the photobleaching profiles of probes against the HA RNA segment for the wild-type influenza A/Puerto Rico/8/34 (PR8) and a recombinant PR8 virus carrying two copies of the HA segment, we concluded that only one copy of HA segment is packaged into a wild type virus particle. Our results showed similar photobleaching behaviors for other RNA segments, suggesting that for the majority of the virus particles, only one copy of each RNA segment is packaged into one virus particle. Together, our results support that the packaging of influenza viral genome is a selective process. PMID:22547828

To analyze the adults' coronary artery anomalies revealed by 64-MDCT, we retrospectively analyzed 34 cases of coronary artery anomalies (26 males and 8 females, averagely aged 53. 4 years with a range from 30 to 72 years). Multi-plannar reconstruction (MPR), maximum intensity projection (MIP), surface shadow display (SSD) and volume rendering (VR) were used to demonstrate the anomalous coronary artery. We found 4 cases of RCA from the left coronary sinus, 8 cases with secondary RCA, 1 case with high locations of left main (LM) segments from left sinus of valves, 1 case with LAD originated from main pulmonary artery, 3 cases with separate origin of LAD and LCX. Ten cases with myocardial bridge were shown (9 cases in LAD, 1 case in LCX); coronary fistula was seen in 2 cases (one was RCA-RA fistula, another was LAD-RV fistula), coronary aneurysm was found in 2 cases. Three cases in RCA were short and small. In conclusion, 64-MDCT is a good choice for diagnosing the anomalous coronary artery. PMID:19634659

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).

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

Odds and ends in psychopharmacology from the past 10 years.  

PubMed

Seven topics previously described in this column are revisited. The use of quantitative electroencephalography has been shown in a prospective study to be effective for predicting antidepressant treatment response. A novel antidepressant drug, agomelatine, has generated much controversy, and its development for the U.S. market was discontinued. A long awaited revised system for categorizing the safety of medications during pregnancy and lactation has finally been published by the Food and Drug Administration. Dextromethorphan/quinidine, eslicarbazepine acetate, levomilnacipran, and esketamine are recent examples of drugs that were developed based on the complex concepts of chirality and stereochemistry. Lisdexamfetamine, a stimulant drug, failed to show benefit as an augmentation therapy for the treatment of depression. The combination drug naltrexone/bupropion was finally approved as a therapy for obesity, after its cardiovascular safety was confirmed in a prospective premarketing study. Further development of the glucocorticoid receptor antagonist drug mifepristone as a treatment for psychotic depression was stopped based on a large negative trial, but the drug continues to be investigated for other potential psychiatric indications. These examples illustrate how the field of psychopharmacology continues to evolve. [Journal of Psychosocial Nursing and Mental Health Services, 53(1), 9-12.]. PMID:25622272

Consistency and universality in odd and even dimensional space-time QFT perturbative calculations  

NASA Astrophysics Data System (ADS)

The questions related to the consistent interpretation of QFT perturbative amplitudes are considered in light of a novel procedure, alternative to the traditional ones based on regularization prescriptions. A detailed discussion about the aspects associated to the space-time dimension is performed. For this purpose, it is considered a simple model having a fermionic vector current, coupled to a vector field, as well as a fermionic scalar current, coupled to a scalar field, both of them composed by different species of massive fermions. The referred currents are related in a precise way, which is reflected in the Ward identities for the perturbative physical amplitudes. The double vector two-point fermionic function, related to the vacuum polarization tensor of QED, as well as the amplitudes related to such quantity through relations among Green functions are explicit evaluated in space-time dimensions d = 2, 3, 4, 5 and 6. In the adopted procedure the perturbative amplitudes are not modified in intermediary steps of the calculations, as occurs in regularization procedures. Divergent Feynman integrals are not really solved. They appear only in standard objects, conveniently defined, where no physical parameter is present. Only very general properties for such quantities are assumed. For the finite parts, a set of functions is introduced which allows universal forms for the results. We show that scale independent, ambiguity free amplitudes are automatically obtained in a regularization independent way. As a consequence, interesting and, in certain way, surprising aspects are revealed in a clear and transparent way when the Ward identities and low-energy limits are verified for the simple amplitudes considered in the presently reported investigation. The obtained results suggest that the procedure can be considered as an advantageous tool to handle with the problem of divergences in perturbative solutions of QFT's, relative to the traditional regularization techniques, since the obtained results are so consistent as desirable and there are no limitations of applicability. In particular, the method can be applied in odd and even space-time dimensions having extra dimensions, which is not possible within the context of traditional regularization.

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

Odd-even staggering in nuclear binding and the liquid-drop model  

E-print Network

The trends with mass number are examined for the odd-even-staggering (OES) in nuclear binding of neutrons and protons through the conventional measures $\\Delta^{(3)}$. The large differences previously observed between these trends for even and odd values of these measures is found to arise, in part, from the slow variation of binding energies with mass and charge which provides a background contribution. This background is estimated with the liquid-drop model, and accounts for the greater difference found in proton removal relative to neutron removal. The differences which persist after backgrounds are removed can not be treated in the conventional liquid-drop model but require the addition of a new term. Such a term is investigated, and its effect on specific values of the OES is calcutated. The liquid-drop fitting is also applied to a set of separation energies constrained to match the specific set of nuclei used to determine the observed values for the odd $\\Delta^{(3)}$. The resulting fit for the pairing term is compared to the average value of even and odd measures. The effect on this value of the new liquid-drop term is observed, and the change in background when the new term is included is also used as an alternate method for determining the difference between trends of the even and odd values of the OES.

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.

Relativistic analysis of magnetoelectric crystals: extracting a new 4-dimensional P odd and T odd pseudoscalar from Cr_2 O_3 data

Earlier, the linear magnetoelectric effect of chromium sesquioxide Cr_2 O_3 has been determined experimentally as a function of temperature. One measures the electric field-induced magnetization on Cr_2 O_3 crystals or the magnetic field-induced polarization. From the magnetoelectric moduli of Cr_2 O_3 we extract a 4-dimensional relativistic invariant pseudoscalar \\tilde\\alpha.

Relativistic analysis of magnetoelectric crystals: extracting a new 4-dimensional P odd and T odd pseudoscalar from Cr_2 O_3 data  

E-print Network

Earlier, the linear magnetoelectric effect of chromium sesquioxide Cr_2 O_3 has been determined experimentally as a function of temperature. One measures the electric field-induced magnetization on Cr_2 O_3 crystals or the magnetic field-induced polarization. From the magnetoelectric moduli of Cr_2 O_3 we extract a 4-dimensional relativistic invariant pseudoscalar \\tilde\\alpha. It is temperature dependent and of the order of ~ 10^{-4} Y_0, with Y_0 as vacuum admittance.

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.

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.

Atmospheric odd oxygen production due to the photodissociation of ordinary and isotopic molecular oxygen  

NASA Technical Reports Server (NTRS)

Line-by-line calculations are performed to determine the contributions of the Schumann-Runge bands of ordinary and isotopic oxygen to the photodissociation of these molecules at different altitudes. The contributions to the dissociation rates of the satellite lines and of the first and higher vibrational states of the initial molecular states are found to be insignificant. At 70 km, (O-16)(O-18) is found to produce 10 times as much odd oxygen as would be produced if the isotope did not have selective absorption, and 6 percent of the odd oxygen produced is due to this isotope. It is noted that the excess odd oxygen produced is not enough to explain the excess quantity of ozone observed in the atmosphere, which cannot be accounted for in photochemical models. Comparison with previous results is made.

On Supergroups with Odd Clifford Parameters and Supersymmetry with Modified Leibniz Rule  

E-print Network

We investigate supergroups with Grassmann parameters replaced by odd Clifford parameters. The connection with non-anticommutative supersymmetry is discussed. A Berezin-like calculus for odd Clifford variables is introduced. Fermionic covariant derivatives for supergroups with odd Clifford variables are derived. Applications to supersymmetric quantum mechanics are made. Deformations of the original supersymmetric theories are encountered when the fermionic covariant derivatives do not obey the graded Leibniz property. The simplest non-trivial example is given by the N=2 SQM with a real $(1,2,1)$ multiplet and a cubic potential. The action is real. Depending on the overall sign ("Euclidean" or "Lorentzian") of the deformation, a Bender-Boettcher pseudo-hermitian hamiltonian is encountered when solving the equation of motion of the auxiliary field. A possible connection of our framework with the Drinfeld twist deformation of supersymmetry is pointed out.

SU(6) quadrupole phonon model for even and odd nuclei and the SU(3) limit  

NASA Astrophysics Data System (ADS)

Analogous to the equivalence between the SU(6) quadrupole-phonon model (TQM) and the interacting boson model (IBM), the equivalence is pointed out for odd systems between the SU(6) particle quadrupole-phonon coupling model (PTQM) and the interacting boson-fermion model (IBFM). PTQM is formulated starting from the Dyson representation for the odd system. Different aspects of the SU(3) limit of TQM and PTQM are studied; the quadrupole-phonon block structure of rotational bands in even and odd nuclei and analytic expressions based on the coherent state; signature effects generated in PTQM; electromagnetic properties and correction factors for PTQM; overlaps of the PTQM analogs of Nilsson states with Coriolis-coupled Nilsson states and the relation to the rotational model representation.

Measurement of lifetimes and tensor polarizabilities of odd parity states of Sm I  

SciTech Connect

A systematic measurement of the lifetimes and tensor polarizabilities of the lowest-lying odd parity levels of Sm I was performed. The lifetimes were measured by detecting time-resolved fluorescence following pulsed laser excitation of atoms in an atomic beam; polarizabilities were measured employing the method of Stark-induced quantum beats. An analysis of the data is undertaken to find the best even parity candidate states for an atomic electric dipole moment (EDM) measurement. A term reassignment of several odd parity states is discussed. For the most favorable candidate state (7G1), the electron EDM enhancement factor is evaluated to be potentially as large as {approximately}10{sup 4}. Critical analysis of the present data along with earlier results in Sm shows the necessity of a term reassignment for several odd parity states. This term reassignment is also used in an estimate of the parity nonconserving 7F0 {r{underscore}arrow} 7G1 amplitude.

Time-delayed feedback control design beyond the odd-number limitation  

NASA Astrophysics Data System (ADS)

We present an algorithm for a time-delayed feedback control design to stabilize periodic orbits with an odd number of positive Floquet exponents in autonomous systems. Due to the so-called odd-number theorem such orbits have been considered as uncontrollable by time-delayed feedback methods. However, this theorem has been refuted by a counterexample and recently a corrected version of the theorem has been proved. In our algorithm, the control matrix is designed using a relationship between Floquet multipliers of the systems controlled by time-delayed and proportional feedback. The efficacy of the algorithm is demonstrated with the Lorenz and Chua systems.

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.

T-odd quark-gluon-quark correlation function in the diquark model  

E-print Network

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.

Charge-odd correlation of lepton and pion pair production in electron-proton scattering  

E-print Network

Charge-odd correlation of the charged pair components produced at electron-proton scattering can measure three current correlation averaged by proton state. In general these type correlation can be described by 14 structure functions. We restrict here by consideration of inclusive distributions of a pair components, which is the light-cone projection of the relevant hadronic tensor. Besides we consider the point-like approximation for proton and pion. Numerical estimations show that charge-odd effects can be measured in exclusive ep -> 2 pi X experiments.

A two-dimensional model of odd nitrogen in the thermosphere and mesosphere  

NASA Technical Reports Server (NTRS)

Satellite measurements of the global nitric oxide distribution demonstrating the need for a two dimensional model of odd nitrogen photochemistry and transport in the thermosphere and mesosphere are reviewed. The main characteristics of a new code solving the transport equation for N(4S), N(2D), and N0 are given. This model extends from pole to pole between 75 and 275 km and reacts to the magnetic activity, the ultraviolet solar flux, and the neutral wind field. The effects of ionization and subsequent odd nitrogen production by high latitude particle precipitation are also included. Preliminary results are illustrated for a magnetically quiet solar minimum period with no neutral wind.

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.

Time Reversal Odd Fragmentation Functions in Semi-Inclusive Scattering of Polarized Leptons from Unpolarized Hadrons  

E-print Network

Semi-inclusive deep inelastic scattering of polarized leptons off hadrons enables one to measure the antisymmetric part of the hadron tensor. For unpolarized hadrons this piece is odd under time reversal. In deep inelastic scattering it shows up as a $\\langle \\sin \\phi \\rangle$ asymmetry for the produced hadrons. This asymmetry can be expressed as the product of a twist-three "hadron $\\rightarrow$ quark" distribution function and a time reversal odd twist-two "quark $\\rightarrow$ hadron" fragmentation function. This fragmentation function can only be measured for nonzero transverse momenta of the produced hadron.

Even-odd Effects of Fragment Yields in Low Energy Fission  

NASA Astrophysics Data System (ADS)

Since the discovery of fission even-odd staggering of proton, neutron and mass yields of the fragments and their energies has been a topic of ongoing research. In the present survey only low energy fission is covered, i.e. spontaneous fission and thermal neutron induced fission of actinides. From studies of fragment yields and their even-odd staggering in cold fission the lesson is drawn that in models of adiabatic fission, where breaking of nucleon pairs is attributed to non- adiabatic neck rupture, two parameters have to be taken into account: neck size and speed of neck rupture.

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.

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.

Dimensionally continued Oppenheimer-Snyder gravitational collapse II: solutions in odd dimensions  

E-print Network

The Lovelock gravity extends the theory of general relativity to higher dimensions in such a way that the field equations remain of second order. The theory has many constant coefficients with no a priori meaning. Nevertheless it is possible to reduce them to two, the cosmological constant and Newton's constant. In this process one separates theories in even dimensions from theories in odd dimensions. In a previous work gravitational collapse in even dimensions was analysed. In this work attention is given to odd dimensions. It is found that black holes also emerge as the final state of gravitational collapse of a regular dust fluid.

Body mass index and anxiety/depression as mediators of the effects of child sexual and physical abuse on physical health disorders in women.  

PubMed

The relation between childhood sexual abuse (CSA) and physical health disorders in adulthood, and what factors may serve as mediators, remains poorly understood. Using data from the 2007 Adult Psychiatric Morbidity Survey (N=3,486), we tested whether CSA was associated with physical health disorders in adult women and if mediated effects via body mass index (BMI), anxiety/depression, alcohol dependence, and smoking were present. Compared to women with no CSA, women who had experienced CSA involving intercourse had more than twice the odds of being obese, more than 3 times the odds of experiencing mental health disorders, more than 4 times the odds of being alcohol dependent, more than 5 times the odds of being drug dependent, and more than 6 times the odds of attempting suicide. Those experiencing both CSA and child physical abuse (CPA) were on average over 11kg heavier than those with neither CSA nor CPA. After controlling for demographics, CPA, and childhood bullying, CSA was associated with the majority of physical health disorders studied (typically 50-100% increases in odds). Evidence was found consistent with mediation by BMI (typically accounting for 5-20% increases in odds) and anxiety/depression (typically accounting for 8-40% increases in odds), in a dose-response manner, for the majority of physical health disorders. Bidirectional relations among these mediators and physical health disorders, and residual confounding, may have led to overestimation of mediation through BMI and anxiety/depression and underestimation of mediation through alcohol/smoking. Relations between both CPA and childhood bullying and physical health disorders in adulthood were also found. Longitudinal studies employing more sensitive measures of potential mediators are now required. PMID:25459987

The configuration-fixed constrained triaxial relativistic mean-field approach is extended by including time-odd fields and applied to study the candidate multiple chiral doublets (MKiD) nucleus 106Rh. The energy contribution from time-odd fields and microscopical evaluation of center-of-mass correction as well as the modification of triaxial deformation parameters beta, gamma due to the time-odd fields are investigated. The contributions of the time-odd fields to the total energy are 0.1-0.3 MeV and they modify slightly the gamma values. However, the previously predicted multiple chiral doublets still exist.

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).

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

Odd-frequency pairing in topological superconductivity in a one-dimensional magnetic chain  

NASA Astrophysics Data System (ADS)

A chain of magnetic atoms with noncollinear spin configuration on a superconductor is a promising new system that can host Majorana fermions (MFs). In this study, we clarify that in the presence of MFs, an odd-frequency Cooper pair is generated at the edge of the chain. Furthermore, it is revealed that this feature is robust against the distance between magnetic atoms as far as this distance is shorter than the coherence length of the superconductor. We also elucidate the close relationship between the pair amplitude of the odd-frequency pair and the direction of the MF spin. If Rashba-type spin-orbit coupling is included, MFs can be realized even in a collinear alignment of magnetic atoms, i.e., in a ferromagnetic or an antiferromagnetic chain on a superconductor. Then, the odd-frequency pairing is generated at the edge, similar to the noncollinear case. Based on our results, it can be concluded that the detection of the zero-energy peak of the local density of states by scanning tunneling microscopy at the edge of the magnetic chain is strong evidence for the generation of odd-frequency pairing.

Redundant prepuce increases the odds of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS)  

PubMed Central

Some published evidence has revealed that the dendritic cells can interact with pathogens that exist in the inner foreskin. This information provides a new vision that pathogens could play a role through the redundant prepuce; numerous studies have failed to find pathogens in prostates of patients who had chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). However, no studies have reported an association between foreskin length and CP/CPPS. Hence, we conducted a retrospective case-control study of clinical data from 322 CP/CPPS patients (case group) and 341 nonCP/CPPS patients (control group). Demographic characteristics, lifestyle factors, and foreskin lengths were collected and analyzed. Multivariate logistic regression was adopted to calculate the odds of foreskin length for CP/CPPS. According to the multivariate logistic regression results, when the foreskin length covered up more than half of the glans penis, the odds for CP/CPPS were higher with an increased foreskin (odds ratio (OR): 1.66, 95% confidence interval (CI): 1.04–2.66). In comparison, when the glans penis was completely covered by the foreskin, the OR value increased to 1.86 (95% CI, 1.2–2.88). The study results showed an association between foreskin length and the odds of CP/CPPS. When the foreskin length covered up more than half of the glans penis, there were greater odds for CP/CPPS. This possible mechanism might result from interaction between pathogens and DCs in the inner foreskin, consequently activating T-cells to mediate allergic inflammation in the prostate and producing the autoimmunizations causing CP/CPPS.

Some useful odds and ends from the n-electron valence state perturbation theory.  

PubMed

The n-electron valence state perturbation theory makes use of zero-order wave functions whose energies are endowed with a direct physical interest, describing various processes occurring in the active space (removal/addition of one or two electrons, electronic excitations). It is shown that the zero-order energies related to the process of removal of an electron from the active space provide a reasonable and cheap approximation to the vertical ionization potentials. The zero-order energies referring to the process of an electronic excitation within the active space can also provide a first approximation to electronic transition energies, provided that a careful choice of the active molecular orbitals is performed. Test calculations have been carried out on the molecules N2 and H2CO. PMID:24784926

Physical activity level and its sociodemographic correlates in a peri-urban Nepalese population: a cross-sectional study from the Jhaukhel-Duwakot health demographic surveillance site  

PubMed Central

Background Physical inactivity is a leading risk factor for cardiovascular and other noncommunicable diseases in high-, low- and middle-income countries. Nepal, a low-income country in South Asia, is undergoing an epidemiological transition. Although the reported national prevalence of physical inactivity is relatively low, studies in urban and peri-urban localities have always shown higher prevalence. Therefore, this study aimed to measure physical activity in three domains—work, travel and leisure—in a peri-urban community and assess its variations across different sociodemographic correlates. Methods Adult participants (n?=?640) from six randomly selected wards of the Jhaukhel-Duwakot Health Demographic Surveillance Site (JD-HDSS) near Kathmandu responded to the Global Physical Activity Questionnaire. To determine total physical activity, we calculated the metabolic equivalent of task in minutes/week for each domain and combined the results. Respondents were categorized into high, moderate or low physical activity. We also calculated the odds ratio for low physical activity in various sociodemographic variables and self-reported cardiometabolic states. Results The urbanizing JD-HDSS community showed a high prevalence of low physical activity (43.3%; 95% CI 39.4–47.1). Work-related activity contributed most to total physical activity. Furthermore, women and housewives and older, more educated and self-or government-employed respondents showed a greater prevalence of physical inactivity. Respondents with hypertension, diabetes or overweight/obesity reported less physical activity than individuals without those conditions. Only 5% of respondents identified physical inactivity as a cardiovascular risk factor. Conclusions Our findings reveal a high burden of physical inactivity in a peri-urban community of Nepal. Improving the level of physical activity involves sensitizing people to its importance through appropriate multi-sector strategies that provide encouragement across all sociodemographic groups.

Effect of solar proton events in 1978 and 1979 on the odd nitrogen abundance in the middle atmosphere  

NASA Technical Reports Server (NTRS)

Daily average solar proton flux data for 1978 and 1979 are used in a proton energy degradation scheme to derive ion pair production rates and atomic nitrogen production rates. The latter are computed in a form suitable for inclusion in an atmopheric, two-dimensional, time-dependent photochemical model. Odd nitrogen distributions are computed from the model, including atomic nitrogen production from solar protons, and are compared with baseline distributions. The comparisons show that the average effect of the solar protons in 1978 and 1979 was to cause changes in odd nitrogen only above 10 mbar and at latitudes only above about 50 deg in both hemispheres. The influence of the solar proton-produced odd nitrogen on the local abundance of odd nitrogen depends primarily on the background odd nitrogen abundance as well as the altitude and season.

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.

Fission studies of secondary beams from relativistic uranium projectiles: The proton even-odd effect in fission fragment charge yields  

SciTech Connect

Nuclear-charge yields of fragments produced by fission of neutron-deficient isotopes of uranium, protactinium, actinium, and radium have been measured. These radioactive isotopes were produced as secondary beams, and electromagnetic fission was induced in a lead target with an average excitation energy around 11 MeV. The local even-odd effect in symmetric and in asymmetric fission of thorium isotopes is found to be independent of Z{sup 2}/A. The charge yields of the fission fragments of the odd-Z fissioning protactinium and actinium show a pronounced even-odd effect. In asymmetric fission the unpaired proton predominantly sticks to the heavy fragment. A statistical model based on the single-particle level density at the Fermi energy is able to reproduce the overall trend of the local even-odd effects both in even-Z and odd-Z fissioning systems.

Multidimensional cut-off technique, odd-dimensional Epstein zeta functions and Casimir energy of massless scalar fields  

E-print Network

Quantum fluctuations of massless scalar fields represented by quantum fluctuations of the quasiparticle vacuum in a zero-temperature dilute Bose-Einstein condensate may well provide the first experimental arena for measuring the Casimir force of a field other than the electromagnetic field. This would constitute a real Casimir force measurement - due to quantum fluctuations - in contrast to thermal fluctuation effects. We develop a multidimensional cut-off technique for calculating the Casimir energy of massless scalar fields in $d$-dimensional rectangular spaces with $q$ large dimensions and $d-q$ dimensions of length $L$ and generalize the technique to arbitrary lengths. We explicitly evaluate the multidimensional remainder and express it in a form that converges exponentially fast. Together with the compact analytical formulas we derive, the numerical results are exact and easy to obtain. Most importantly, we show that the division between analytical and remainder is not arbitrary but has a natural physical interpretation. The analytical part can be viewed as the sum of individual parallel plate energies and the remainder as an interaction energy. In a separate procedure, via results from number theory, we express some odd-dimensional homogeneous Epstein zeta functions as products of one-dimensional sums plus a tiny remainder and calculate from them the Casimir energy via zeta function regularization.

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). Two other conditions, pneumonia and pancreatitis, as well as tuberculosis, were significant at p < .05 but below the statistical threshold used to reduce alpha error. 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

Regularization of energy-momentum tensor correlators and parity-odd terms

We discuss the problem of regularizing correlators in conformal field theories. The only way to do it in coordinate space is to interpret them as distributions. Unfortunately except for the simplest cases we do not have tabulated mathematical results. The way out we pursue here is to go to momentum space and use Feynman diagram techniques and their regularization methods. We focus on the energy-momentum tensor correlators and, to gain insight, we compute and regularize 2-point functions in 2d with various techniques both in coordinate space and in momentum space, obtaining the same results. Then we do the same for 2-point functions in 4d. Finally we turn to 3-point function in 4d, and concentrate on the parity-odd part. We derive in particular the regularized trace and divergence of the energy-momentum tensor in a chiral fermion model. We discuss the problems related to the parity-odd trace anomaly.

Phase modulating with odd and even finite power series of a modulating signal  

NASA Technical Reports Server (NTRS)

Method and apparatus is presented for producing a phase-modulated waveform having a high degree of linearity between the modulating signal and the phase of the modulated carrier signal. Two signals representing finite odd and even power series transformations of the modulating signal are produced and multiplied with two quadrature components of the input carrier signal, respectively. One of the multiplied signals is subtracted from the other and the resulting signal is hard-limited to produce a phase-modulated output signal. The means for producing the two signals representing the odd and even power series of the modulating signal includes means for varying the coefficients of the two power series. By means of an existing computer program, the coefficients of the two power series are selected such that there is an extremely high degree of linearity between the modulating signal and the phase of the modulated carrier signal.

Rapid deactivation of N(2D) by O - Impact on thermospheric and mesospheric odd nitrogen  

NASA Technical Reports Server (NTRS)

One- and two-dimensional models of thermospheric odd nitrogen are used to explore the consequences of the recently measured fast quenching of N(2D) by O. A large rate coefficient for this reaction profoundly affects the odd-nitrogen chemistry by removing N(2D) as a source of NO and increasing the concentration of N(4S), which destroys NO. The model calculations show that, as the quenching rate increases, the NO and N(2D) densities decrease, while N(4S) densities increase. Comparisons with Atmosphere Explorer and Solar Mesosphere Explorer satellite observations are made. Use of the fast quenching rate in the models causes the NO peak altitude, typically observed near 110 km, to rise to 140 km.

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.

Parity-odd correlators of diffuse gamma-rays and intergalactic magnetic fields  

NASA Astrophysics Data System (ADS)

We develop the connection between intergalactic helical magnetic fields and parity-odd signatures in the diffuse gamma-ray sky. We find that the location and the amplitude of a peak in a parity-odd correlator, Q(R), can be used to infer the normal and helical power spectra of the intergalactic magnetic field. When applied to Fermi-LAT data, the amplitude of the observed peak in Q(R) gives ˜10-14 G intergalactic magnetic field strength, which is consistent with an earlier independent estimate that only used the peak location (Tashiro et al. 2014). We discuss features in the observed Q(R) that further support the intergalactic magnetic field hypothesis and make predictions for future tests.

T-odd Asymmetry in W+jet Events at the LHC  

E-print Network

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 na$\\ddot{\\i}$ve-T-reversal where both the three-momenta and angular momenta are reversed.

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.

Chiral-odd generalized parton distributions in transverse and longitudinal impact parameter spaces  

NASA Astrophysics Data System (ADS)

We investigate the chiral-odd generalized parton distributions for nonzero skewness ? in transverse and longitudinal position spaces by taking Fourier transform with respect to the transverse and longitudinal momentum transfer, respectively. We present overlap formulas for the chiral-odd generalized parton distributions in terms of light-front wave functions (LFWFs) of the proton both in the Efremov-Radyushkin-Brodsky-Lepage and Dokshitzer-Gribov-Lipatov-Altarelli-Parisi regions. We calculate them in a field theory inspired model of a relativistic spin-1/2 composite state with the correct correlation between the different LFWFs in Fock space, namely, that of the quantum fluctuations of an electron in a generalized form of QED. We show the spin-orbit correlation effect of the two-particle LFWF as well as the correlation between the constituent spin and the transverse spin of the target.

Magnetic moments of $^{33}$Mg in time-odd relativistic mean field approach  

E-print Network

The configuration-fixed deformation constrained relativistic mean field approach with time-odd component has been applied to investigate the ground-state properties of $^{33}$Mg with effective interaction PK1. The ground state of $^{33}$Mg has been found to be prolate deformed, $\\beta_2=0.23$, with the odd neutron in $1/2[330]$ orbital and the energy -251.85 MeV which is close to the data -252.06 MeV. The magnetic moment $- 0.9134 \\mu_\\mathrm{N}$ is obtained with the effective electromagnetic current which well reproduces the data $- 0.7456 \\mu_\\mathrm{N}$ self-consistently without introducing any parameter. The energy splittings of time reversal conjugate states, the neutron current, the energy contribution from the nuclear magnetic potential, and the effect of core polarization are discussed in detail.

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

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.

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_equal}28({h_bar}/2{pi})) 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.

Parity-odd and CPT-even electrodynamics of the standard model extension at finite temperature  

NASA Astrophysics Data System (ADS)

This work examines the finite temperature properties of the CPT-even and parity-odd electrodynamics of the standard model extension. The starting point is the partition function computed for an arbitrary and sufficiently small tensor (kF)???? [see R. Casana, M. M. Ferreira, Jr., J. S. Rodrigues, and M. R. O. Silva, Phys. Rev. DPRVDAQ1550-7998 80, 085026 (2009).10.1103/PhysRevD.80.085026]. After specializing the Lorentz-violating tensor (kF)???? for the leading-order-nonbirefringent and parity-odd coefficients, the partition function is explicitly carried out, showing that it is a power of the Maxwell partition function. Also, it is observed that the Lorentz invariance violation coefficients induce an anisotropy in the black-body angular energy density distribution. Planck’s radiation law retains its usual frequency dependence and the Stefan-Boltzmann law keeps the same form, except for a global proportionality constant.

A Codicil To Massless Gauge Superfields of Higher Half-Odd Integer Superspins  

E-print Network

We study theories of 4D, N=1 supersymmetric massless, arbitrary higher half odd-integer superspins. A new series of such theories is found to exist for arbitrary superspin Y (Y=s+1/2 for any integer s). The lowest member (s=1) of the series is the original off-shell formulation of 4D, N=1 supergravity first presented by Breitenlohner in 1977.

Charged squashed black holes with negative cosmological constant in odd dimensions  

E-print Network

We construct new electrically charged solutions of the Einstein-Maxwell equations with negative cosmological constant in general odd dimensions $d=2n+3 \\geq 5$. They correspond to higher dimensional generalizations of the squashed black hole solutions, which were known so far only in five dimensions. We explore numerically the general properties of such classical solutions and, using a counterterm prescription, we compute their conserved charges and discuss their thermodynamics.

High-spin collective structures in doubly-odd 114Sb  

Microsoft Academic Search

Several collective rotational bands have been established in doubly-odd 114Sb extending to high spin (~35h) and excitation energy (~18 MeV). Two pairs of strongly coupled negative-parity sequences were observed at low spin consisting of stretched quadrupole transitions and interlinking M1 dipole transitions. These bands are intepreted in terms of the pi[404]9\\/2+ orbital. A third pair of signature-partner bands was established;
