    2005-01-01

    We review our recent studies on the effects of CP-violating supersymmetric (SUSY) parameters on the phenomenology of neutralinos, charginos and third generation squarks. The CP-even branching ratios of the squarks show a pronounced dependence on the phases of A_t, A_b, mu and M_1 in a large region of the supersymmetric parameter space, which can be used to get information on these phases. In addition we have studied CP-odd observables, like asymmetries based on triple product correlations. In neutralino and chargino production with subsequent three-body decays these asymmetries can be as large as 20%.

    In the Minimal Supersymmetric Standard Model, physical phases of complex parameters lead to CP violation. We show how triple products of particle momenta or spins can be used to construct asymmetries, that allow us to probe these CP phases. To give specific examples, we discuss the production of neutralinos at the International Linear Collider. For the Large Hadron Collider, we discuss CP asymmetries in squark decays, and in the tri-lepton signal. We find that the CP asymmetries can be as large as 60%.

    In the Minimal Supersymmetric Standard Model, physical phases of complex parameters lead to CP violation. We show how triple products of particle momenta or spins can be used to construct asymmetries, that allow us to probe these CP phases. To give specific examples, we discuss the production of neutralinos at the International Linear Collider (ILC). For the Large Hadron Collider (LHC), we discuss CP asymmetries in squark decays, and in the tri-lepton signal. We find that the CP asymmetries can be as large as 60%.

  4. Distinguishable RGE Running Effects Between Dirac Neutrinos and Majorana Neutrinos with Vanishing Majorana CP-Violating Phases

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    In a novel parametrization of neutrino mixing and in the approximation of т-lepton dominance, we show that the one-loop renormalization-group equations (RGEs) of Dirac neutrinos are different from those of Majorana neutrinos even if two Majorana CP-violating phases vanish. As the latter can keep vanishing from the electroweak scale to the typical seesaw scale, it makes sense to distinguish between the RGE running effects of neutrino mixing parameters in Dirac and Majorana cases. The differences are found to be quite large in the minimal supersymmetric standard model with sizable tanβ, provided the masses of three neutrinos are nearly degenerate or have an inverted hierarchy.

    On the basis of the Froggatt-Nielsen mechanism, we study quark flavor mixings in the $SU(6) \\times SU(2)_R$ model. The characteristic structure of the CKM matrix is attributed to the hierarchical effective Yukawa couplings due to the Froggatt-Nielsen mechanism and also to the state-mixings beyond the MSSM. We elucidate the detailed form of the CKM matrix elements and find interesting relations between the CP violating phase and three mixing angles. Taking the existing data of three mixing angles, we estimate the quark CP-phase at $\\delta = (75 \\pm 3)^{\\circ}$. This result is in accord with observations.

    We assess the sensitivity to the lepton CP phase by accelerator and reactor experiments in the near future, characterizing it globally by means of the CP exclusion fraction measure. Such measure quantifies what fraction of the $\\delta_{\\rm CP}$ space can be excluded at given input values of $\\theta_{23}$ and $\\delta_{\\rm CP}$. For some region of the parameter space, we find that T2K and NO$\

Changes to the limit due to SU(3) symmetry breaking effects are also discussed.

    2006-01-01

    Based on theories of heat transfer, physical metallurgy and hydro-mechanical, in order to analyze the effect of welding parameters on species and distribution of reinforcing phases visually and legibly,finite element software ANSYS was used to simulate transient temperature field for SiCp/Al in " in-situ" weld-alloying/plasma arc welding. The results show that the calculated results approximately agreed with the experimental measured results. So the model is basically correct and credible. Based on the numerical solutions and experimental results, effect of temperature field in different welding process parameters( welding current, welding velocity) on species and distribution of reinforcing phases is analyzed. The results show that adjusting and optimizing temperature field appropriately is an effective method to obtain welded joint with better microstructure and property.

    We study the effects of considering nontrivial unphysical lepton sector phases on the group theoretical properties of the flavor and generalized CP symmetry elements in the case where there are three light, distinct Majorana neutrino species. This approach highlights the similarities and differences between generalized CP symmetries in the charged lepton and neutrino sectors while further elucidating the group properties of the generalized CP symmetry elements.

  11. Connecting nonzero θ 13, Dirac CP phase and leptogenesis through spontaneous CP violation

    Science.gov (United States)

    Karmakar, Biswajit; Sil, Arunansu

    2017-09-01

    We have analyzed a Type-I+II seesaw scenario to generate neutrino masses and mixing in a A 4 based flavor symmetric framework. The Standard Model (SM) particle content is extended by three singlet right handed neutrinos, an additional higgs triplet along with few SM singlet flavon fields. In this set-up, the pure type-I contribution to the neutrino mass matrix exhibits a tribimaximal (TBM) of lepton mixing where the triplet contribution generates θ 13. Complex vev of one flavon provides a unique source of spontaneous CP violation. Here it turns out that the triplet contribution provides a common source for θ 13, Dirac CP phase (δ) and CP violation required for leptogenesis.

  12. CP phase from twisted Higgs VEV in extra dimension

    CERN Document Server

    Fujimoto, Yukihiro; Sakamoto, Makoto

    2013-01-01

    We propose a new mechanism for generating CP phase via Higgs vacuum expectation value originating from geometry of an extra dimension. Allowing a twisted boundary condition for the Higgs doublet drives us into an extra-dimension-coordinate-dependent vacuum expectation value containing a CP phase degree of freedom. With this mechanism, we construct a phenomenological model on S1 which can simultaneously and naturally explain the origin of fermion generation, quark mass hierarchy, and the structure of the Cabibbo-Kobayashi-Maskawa matrix with the CP phase. By introducing point interactions, which are additional boundary points on S1, the 5D quarks realize the three generations. Our situation is phenomenologically-preferred one since all the flavor structures are realized with good precision and almost all dimensionless scaled parameters take values of natural O(10) magnitudes. An almost exponential vacuum expectation value profile of a scalar singlet, which appears in the Yukawa sector, helps the naturalness in...

  13. The leptonic Dirac CP-violating phase from sum rules

    Science.gov (United States)

    Girardi, I.; Petcov, S. T.; Titov, A. V.

    2016-05-01

    In the reference 3-neutrino mixing scheme with three light massive neutrinos, CP-violating effects in neutrino oscillations can be caused by the Dirac CP-violating phase δ present in the unitary neutrino mixing matrix U. Using the fact that U = U†eUv , where Ue and Uv are unitary matrices arising from the diagonalisation, respectively, of the charged lepton and neutrino mass matrices, we consider in a systematic way forms of Ue and Uv allowing us to express δ as a function of the neutrino mixing angles present in U and the angles contained in Uv. After obtaining sum rules for cos δ, we consider several forms of Uv dictated by, or associated with, symmetries, such as tri-bimaximal, bimaximal, etc., for which the angles in Uv are fixed. For each of these forms and forms of Ue allowing to reproduce the measured values of the neutrino mixing angles, we construct the likelihood function for cos δ, using the prospective uncertainties in the determination of the mixing angles. Our results show that the measurement of δ along with improvement of the precision on the neutrino mixing angles can provide unique information about the possible existence of a new fundamental symmetry in the lepton sector.

  14. Precise predictions of neutrino mixing angles and $CP$ phase

    CERN Document Server

    Abbas, Gauhar

    2016-01-01

    The neutrino mixing parameters are studied using renormalization-group evolution of Dirac neutrinos with recently proposed parameterization of the neutrino mixing angles referred as `high-scale mixing relations'. The correlations among all neutrino mixing and $CP$ violating parameters are investigated. The predictions for the neutrino mixing angles and the $CP$ phase are precise and could be easily tested by ongoing and future experiments. We observe that the high scale mixing unification hypothesis is incompatible with Dirac neutrinos due to updated experimental data.

  15. Baryogenesis via leptonic CP-violating phase transition

    Pascoli, Silvia; Zhou, Ye-Ling

    2016-01-01

    We propose a new mechanism to generate a lepton asymmetry based on the vacuum CP-violating phase transition (CPPT). This approach differs from classical thermal leptogenesis as a specific seesaw model, and its UV completion, need not be specified. The lepton asymmetry is generated via the dynamically realised coupling of the Weinberg operator during the phase transition. This mechanism provides strong connections with low-energy neutrino experiments.

    We compute the CP violating decay asymmetries relevant for baryogenesis scenarios involving the out of equilibrium decays of heavy particles, including the finite temperature effects arising from the background of light thermal particles which are present during the decay epoch. Thermal effects can modify the size of CP violation by a sizeable fraction in the decay of scalar particles, but we find interesting cancellations in the thermal corrections affecting the asymmetries in the decays of fermions, as well as in the decay of scalars in supersymmetric theories. We also estimate the effects which arise from the motion of the decaying particles with respect to the background plasma.

  17. CP-violating phase on magnetized toroidal orbifolds

    Kobayashi, Tatsuo; Tatsuta, Yoshiyuki

    2016-01-01

    We study the CP-violating phase of the quark sector in the $U(8)$ flavor model on $T^2/Z_N \\, (N=2,3,4,6)$ with non-vanishing magnetic fluxes, where properties of possible origins of the CP violation are investigated minutely. In this system, a non-vanishing value is mandatory in the real part of the complex modulus parameter $\\tau$ of the two-dimensional torus. On $T^2$ without orbifolding, underlying discrete flavor symmetries severely restrict the form of Yukawa couplings and it is very difficult to reproduce the observed pattern in the quark sector including the CP-violating phase $\\delta_{\\rm CP}$. In cases of multiple Higgs doublets emerging on $T^2/Z_2$, the mass matrices of the zero-mode fermions can be written in the Gaussian textures by choosing appropriate configurations of vacuum expectation values of the Higgs fields. When such Gaussian textures of mass matrices are realized, we show that all of the quark profiles, which are mass hierarchies among the quarks, quark mixing angles, and $\\delta_{\\rm...

  18. CP violating phase from minimal texture neutrino mass matrix: Test of the phase relevant to leptogenesis

    CERN Document Server

    Fukugita, Masataka; Shimizu, Yusuke; Tanimoto, Morimitsu; Yanagida, Tsutomu T

    2016-01-01

    The model of neutrino mass matrix with minimal texture is now tightly constrained by experiment so that it can yield a prediction for the phase of CP violation. This phase is predicted to lie in the range $\\delta_{CP}=0.77\\pi - 1.24\\pi$. If neutrino oscillation experiment would find the CP violation phase outside this range, this means that the minimal-texture neutrino mass matrix, the element of which is all real, fails and the neutrino mass matrix must be complex, i.e., the phase must be present that is responsible for leptogenesis.

  19. CP-violating Phases in Active-Sterile Solar Neutrino Oscillations

    CERN Document Server

    Long, H W; Giunti, C

    2013-01-01

    Effects of CP-violating phases in active-sterile solar neutrino oscillations are discussed in a general scheme of 3+N_{s} mixing, without any constraint on the mixing between the three active and the N_{s} sterile neutrinos, assuming only a realistic hierarchy of neutrino mass-squared differences. A generalized Parke formula describing the neutrino oscillation probabilities inside the Sun is calculated. The validity of the analytical calculation and the probability variation due to the unknown CP-violating phases are illustrated with a numerical calculation of the evolution equation in the case of 3+1 neutrino mixing.

    In a recently proposed renormalizable model of neutrino mixing using the non-Abelian discrete symmetry T_7 in the context of a supersymmetric extension of the Standard Model with gauged U(1)_{B-L}, a correlation was obtained between \\theta_{13} and \\theta_{23} in the case where all parameters are real. Here we consider all parameters to be complex, thus allowing for one Dirac CP phase \\delta_{CP} and two Majorana CP phases \\alpha_{1,2}. We find a slight modification to this correlation as a function of \\delta_{CP}. For a given set of input values of \\Delta m^2_{21}, \\Delta m^2_{32}, \\theta_{12}, and \\theta_{13}, we obtain \\sin^2 2 \\theta_{23} and m_{ee} (the effective Majorana neutrino mass in neutrinoless double beta decay) as functions of \\tan \\delta_{CP}. We find that the structure of this model always yields small |\\tan \\delta_{CP}|.

    We show that the coherent phase involved in the neutrino oscillation formalism can be decomposed into two parts, one corresponding to the usual energy-dependent dynamical phase and the other part being the achromatic geometric phase. This study was carried out specifically for (a) CP conserving two flavor case [P. Mehta. Topological phase in two flavor neutrino oscillations. Phys. Rev. D, 79:096013, 2009.] and (b) CP violating two flavor case [P. Mehta. Geometric imprint of cp violation in two flavor neutrino oscillations. (arXiv:0907.0562 [hep-ph]).]. We noted that the geometric phase is actually topological for case (a) irrespective of details of evolution while it can become geometric in case (b).

    In the next generation of long-baseline neutrino oscillation experiments, aiming to determine the charge-parity violating phase $\\delta_{CP}$ in the appearance channel, fine-grained time-projection chambers are expected to play an important role. In this Letter, we analyze an influence of realistic detector capabilities on the $\\delta_{CP}$ sensitivity for a setup similar to that of the Deep Underground Neutrino Experiment. We find that the effect of the missing energy, carried out by undetected particles, is sizable. Although the reconstructed neutrino energy can be corrected for the missing energy, the accuracy of such procedure has to exceed 20\\%, to avoid a sizable bias in the extracted $\\delta_{CP}$ value.

    Using the unitarity, SU(2) and $C$-invariance of hadronic interactions, the bounds on final state phases are derived. It is shown that values obtained for the final state phases relevant for the direct CP-asymmetries $A_{CP}(B^{0}\\to K^{+}\\pi ^{-},K^{0}\\pi ^{0})$ are compatiable with experimental values for these asymmetries. For the decays $B^{0}\\to D^{(\\ast)-}\\pi ^{+}$ $(D^{(\\ast)+}\\pi ^{-})$ described by two independent single amplitudes $A_{f}$ and $A_{\\bar{f}}^{\\prime}$ with differnt weak phases (0 and $\\gamma $) it is argued that the $C$-invariance of hadronic interactions implies the equality of the final state phase $\\delta_{f}$ and $\\delta_{\\bar{f}}^{\\prime}$. This in turn implies, the CP-asymmetry $% \\frac{S_{+}+S_{-}}{2}$ is determined by weak phase ($2\\beta +\\gamma)$ only whereas $\\frac{S_{+}-S_{-}}{2}=0.$ Assuming factorization for tree graphs, it is shown that the $B\\to D^{(\\ast)}$ form factors are in excellent agreement with heavy quark effective theory.

    A model independent analysis of the leptonic Dirac CP-violating phase (δ) is presented. The analysis uses the experimentally determined values of the mixing angles in the lepton mixing matrix in order to explore the allowed values for δ and possible general forms for the charged lepton mixing matrix. This is done under two general assumptions: 1) that the mixing matrix in the neutrino sector is the so-called tribimaximal matrix and hence the non zero value for θ{sub 13} arises due to the mixing matrix in the charged lepton sector and 2) the charged lepton mixing matrix is parametrized in terms of three angles and one phase. It is found that any value of δ is still consistent with the data and that, considering the assumptions above, regardless of the value for δ, the 1−3 mixing angle in the charged lepton sector is small but non zero and the 2−3 mixing angle can take values in only two possible small ranges around 0 and π/2 respectively.

    Unparticles proposed by Georgi carry CP conserving phases in their propagators. We demonstrate that these peculiar phases have an important impact on CP violation. Without including the strong QCD phases, we study the unparticle phase effects on the direct CP asymmetries in the exclusive decays of $\\bar B_d\\to \\pi^{+} \\pi^{-}$ and $B\\to \\pi K$, in which the flavor changing neutral currents are forbidden at tree level but induced by one-loop diagrams. Interesting and consistent results comparing to the data are obtained. In addition, we find that unparticles will significantly enhance the differential branching ratio of $b\\to s \\ell^{+} \\ell^{-}$ at the small invariant mass of $\\ell^{+} \\ell^{-}$. The forward-backward asymmetries for $b\\to s \\ell^{+} \\ell^{-}$ due to unparticles are also explored.

    The CP-violating asymmetries in the exclusive decay B->K^*l^+l^- (l=e,mu,tau) are predicted to be exceedingly small in the standard model (SM), thereby offering an opportunity to assess various new physics scenarios. We derive quantitative predictions for various integrated observables in B->K^*mu^+mu^- decay in the presence of physics beyond the SM with additional CP phases and an extended operator basis. In particular, a model-independent analysis of CP asymmetries that require the presence of unitarity phases, in addition to CP violation, is performed. We find that in the low dimuon invariant mass region 2m_mus gamma rate and the upper limit on BR(B^0->K^{*0}mu^+mu^-), CP-violating effects of a few per cent are estimated, even in the presence of new physics with CP phases of O(1). By contrast, in the high dimuon invariant mass region M_{psi'}< M_{mu^+mu^-}<(M_B-M_{K^*}) significant CP-violating effects are possible. Given a branching ratio of 1.8 x 10^{-6}, the CP asymmetries can be quite substantial...

    CpG oligonucleotide 7909 (CpG 7909, PF-03512676), a synthetic 24mer single stranded agonist of TLR9 expressed by B cells and plasmacytoid dendritic cells, is immunomodulatory and can cause activation-induced death of chronic lymphocytic leukemia (CLL) cells. We report a phase I study of CpG 7909 in 41 patients with early relapsed CLL. A single intravenous dose of CpG 7909 was well tolerated with no clinical effects and no significant toxicity up to 1.05 mg/kg. Single dose subcutaneous CpG 7909 had a maximum tolerated dose (MTD) of 0.45 mg/kg with dose limiting toxicity of myalgia and constitutional effects. Multiple weekly subcutaneous doses at the MTD were well tolerated. CpG 7909 administration induced immunologic changes in CLL and non-malignant cells that were dose and route dependent. We conclude that multidose therapy with subcutaneous CpG 7909 (0.45 mg/kg) could be used in future phase II combination clinical trials for CLL.

    2016-01-01

    Non-unitary neutrino mixing implies an extra CP violating phase that can fake the leptonic Dirac CP phase $\\delta_{CP}$ of the simplest three-neutrino mixing benchmark scheme. This would hinder the possibility of probing for CP violation in accelerator-type experiments. We take T2K and T2HK as examples to demonstrate the degeneracy between the "standard" (or "unitary") and "non-unitary" CP phases. We find, under the assumption of non-unitary mixing, that their CP sensitivities severely deteriorate. Fortunately, the TNT2K proposal of supplementing T2(H)K with a $\\mu$DAR source for better measurement of $\\delta_{CP}$ can partially break the CP degeneracy by probing both $\\cos \\delta_{CP}$ and $\\sin \\delta_{CP}$ dependences in the wide spectrum of the $\\mu$DAR flux. We also show that the further addition of a near detector to the $\\mu$DAR setup can eliminate the degeneracy completely.

    In the CP-violating Minimal Supersymmetric Standard Model, we study the pair production of neutralinos at center-of-mass energies around the heavy neutral Higgs boson resonances. For longitudinally polarized muon beams, we analyze CP asymmetries which are sensitive to the interference of the two heavy neutral Higgs bosons. Due to radiatively induced scalar-pseudoscalar transitions, the CP asymmetries can be strongly enhanced when the resonances are nearly degenerate, as in the Higgs decoupling limit. The Higgs couplings to the neutralino sector can then be analyzed in the presence of CP violating phases. We present a detailed numerical analysis of the cross sections, neutralino branching ratios, and the CP observables. We find that radiatively induced CP violation in the Higgs sector leads to sizable CP-asymmetries, which are accessible in future measurements at a muon collider. However, we expect that our proposed method should be applicable to other processes with nearly degenerate scalar resonances, even a...

    The phenomenon of neutrino oscillation is now well understood from the solar, atmospheric, reactor and accelerator neutrino experiments. This oscillation is characterized by a unitary PMNS matrix which is parametrized by three mixing angles (12, 23 and 13) and one phase (CP) known as the leptonic CP phase. Neutrino oscillation also involves two mass squared differences: the solar mass square difference (21 = 22 − 21) and the atmospheric mass square difference (31 = |23−21|). Though there is already significant amount of information about the three mixing angles, the CP phase is still unknown. Apart from the CP phase, one should also know what is the true nature of the neutrino mass hierarchy, i.e., normal (3 > 1: NH) or inverted (1 > 3: IH) and what is the true octant of 23, i.e., lower (23 < 45°: LO) or higher (23 > 45°: HO). The long-baseline experiments (LBL) have CP sensitivity coming from the appearance channel $(\

    We use a new weak basis invariant approach to classify all the observable phases in any extension of the Standard Model (SM). We apply this formalism to determine the invariant CP phases in a simplified version of the Minimal Supersymmetric SM with only three non-trivial flavour structures. We propose four experimental measures to fix completely all the observable phases in the model. After these phases have been determined from experiment, we are able to make predictions on any other CP-violating observable in the theory, much in the same way as in the Standard Model all CP-violation observables are proportional to the Jarlskog invariant.

    We discuss the connection between observable CP violation in the lepton sector, the properties of heavy neutrinos and the baryon asymmetry of the universe in the minimal seesaw model. A measurement of the Dirac phase $\\delta$ would allow to make testable predictions for the couplings of the heavy neutrinos to individual Standard Model lepton flavours. If any heavy neutral leptons are experimentally discovered in the future, this provides a powerful test for the mechanism of neutrino mass generation and baryogenesis.

    We show that the neutrino mass matrix of the Zee-Babu model is able to fit the most recent data on neutrino masses and mixing with large $\\theta_{13}$ and provides %the values of the Dirac and Majorana CP violation phases. For the normal hierarchy, the Majorana phases ($\\al_{2 1}, \\al_{3 1}$) are equal to zero, while for the inverted pattern, one phase ($\\al_{3 1}$) takes the value $2 \\pi$. The Dirac phase ($\\de$) is predicted to either $0$ or $\\pi$. The effective mass governing neutrinoless double beta decay and the sum of neutrino masses are consistent with the recent analysis. The model gives some regions of the parameters of neutrino mixing angles in both normal and inverted neutrino mass hierarchy.

    Full Text Available Generalised CP transformations are the only known framework which allows to predict Majorana phases in a flavour model purely from symmetry. For the first time generalised CP transformations are investigated for an infinite series of finite groups, Δ(6n2=(Zn×Zn⋊S3. In direct models the mixing angles and Dirac CP phase are solely predicted from symmetry. The Δ(6n2 flavour symmetry provides many examples of viable predictions for mixing angles. For all groups the mixing matrix has a trimaximal middle column and the Dirac CP phase is 0 or π. The Majorana phases are predicted from residual flavour and CP symmetries where α21 can take several discrete values for each n and the Majorana phase α31 is a multiple of π. We discuss constraints on the groups and CP transformations from measurements of the neutrino mixing angles and from neutrinoless double-beta decay and find that predictions for mixing angles and all phases are accessible to experiments in the near future.

    We investigate the associated production of neutralinos $e^+e^-\\to\\tilde{\\chi}^0_1\\tilde{\\chi}^0_2$ accompanied by the neutralino leptonic decay $\\tilde{\\chi}^0_2\\to\\tilde{\\chi}^0_1 \\ell^+\\ell^-$, taking into account initial beam polarization and production-decay spin correlations in the minimal supersymmetric standard model with general CP phases but without generational mixing in the slepton sector. The stringent constraints from the electron EDM on the CP phases are also included in the discussion. Initial beam polarizations lead to three CP-even distributions and one CP-odd distribution, which can be studied independently of the details of the neutralino decays. We find that the production cross section and the branching fractions of the leptonic neutralino decays are very sensitive to the CP phases. In addition, the production-decay spin correlations lead to several CP-even observables such as lepton invariant mass distribution, and lepton angular distribution, and one interesting T-odd (CP-odd) triple p...

    A first flavor-tagged measurement of the time-dependent CP-violating asymmetry in B(s)(0) → ϕϕ decays is presented. In this decay channel, the CP-violating weak phase arises due to CP violation in the interference between B(s)(0)-B(s)(0) mixing and the b → sss gluonic penguin decay amplitude. Using a sample of pp collision data corresponding to an integrated luminosity of 1.0 fb(-1) and collected at a center-of-mass energy of 7 TeV with the LHCb detector, 880 B(s)(0) → ϕϕ signal decays are obtained. The CP-violating phase is measured to be in the interval [-2.46,-0.76] rad at a 68% confidence level. The p value of the standard model prediction is 16%.

    It has recently been shown that by measuring the transverse polarization of the final particles in the LFV processes $\\mu \\to e\\gamma$, $\\mu \\to eee$ and $\\mu N\\to e N$, one can derive information on the CP-violating phases of the underlying theory. We derive formulas for the transverse polarization of the final particles in terms of the couplings of the effective potential leading to these processes. We then study the dependence of the polarizations of $e$ and $\\gamma$ in the $\\mu \\to e \\gamma$ and $\\mu N \\to e N$ on the parameters of the Minimal Supersymmetric Standard Model (MSSM). We show that combining the information on various observables in the $\\mu \\to e\\gamma$ and $\\mu N\\to e N$ search experiments with the information on the electric dipole moment of the electron can help us to solve the degeneracies in parameter space and to determine the values of certain phases.

    We investigate the time-evolutions of angular distributions for B_s decays into final states that are admixtures of CP-even and CP-odd configurations. A sizable lifetime difference between the B_s mass eigenstates allows a probe of CP violation in time-dependent untagged angular distributions. Interference effects between different final state configurations of B_s\\to D^{*+}_s D^{*-}_s, J/\\psi \\phi determine the Wolfenstein parameter \\eta from untagged data samples, or -- if one uses |V_{ub}|/|V_{cb}| as an additional input -- the notoriously difficult to measure CKM angle \\gamma. Another determination of \\gamma is possible by using isospin symmetry of strong interactions to relate untagged data samples of B_s\\to K^{\\ast+} K^{\\ast-} and B_s\\to K^{\\ast0} \\overline{K^{\\ast0}}. We note that the untagged angular distribution for B_s\\to\\rho^0 \\phi provides interesting information about electroweak penguins.

    2005-01-01

    In the standard electroweak model, the sole source of CP violation is a CP violating phase of the CKM quark mixing matrix. The minimal supersymmetric extension of the standard model offers a large number of possible new sources of CP violation; these include both flavor dependent and flavor independent sources. These CP violating effects are studied in gauge boson production and decay processes with intermediate W and Z boson exchange. The prospects of measuring these effects in the International Linear Collider are explored.

    The wettability, incorporation, and gravity segregation of TiC and B4C particles into molten aluminum are important problems in the production of Al-TiC and Al-B4C composites by the casting techniques. In order to solve these problems, different methods consisting of adding the Na3AlF6 and K2TiF6 fluxes and Mg (as the alloying element) into the molten aluminum and injection of the (Al + TiC)CP and (Al + B4C)CP composite powders instead of B4C and TiC particles are evaluated. In this work, the conditions of sample preparation, such as particle addition temperature, stirring speed, and stirring time, are determined after many studies and tests. Microstructural characterizations of samples are investigated by scanning electron microscopy equipped with energy dispersive spectroscopy (EDS) and X-ray diffractometry. The results show better distribution and incorporation of TiCp and B4Cp in aluminum matrix when the fluxes are used, as well as EDS analysis of the interface between the matrix and reinforcement-strengthened formation of the different phases such as Al4C3 in the Al-TiC composites and Al3BC, TiB2 in the Al-B4C composites.

    The seesaw mechanism to derive the light masses of left-handed neutrinos using heavy masses of right-handed neutrinos gives rise to a connection between low-energy measurables and GUT-scale mechanism. We expresses the neutrino mixing angles in terms of a single variable $\\sin\\theta_{13}$, whose size was measured recently. The lepton asymmetry from heavy neutrinos via Yukawa coupling is described by CP phases in both Dirac and Majorana type. It is shown that the seesaw scale relevant to the lepton asymmetry can be constrained by CP phase in this minimal model.

  14. Predicting the values of the leptonic CP violation phases in theories with discrete flavour symmetries

    2015-03-01

    Full Text Available Using the fact that the neutrino mixing matrix U=Ue†Uν, where Ue and Uν result from the diagonalisation of the charged lepton and neutrino mass matrices, we consider a number of forms of Uν associated with a variety of discrete symmetries: i bimaximal (BM and ii tri-bimaximal (TBM forms, the forms corresponding iii to the conservation of the lepton charge L′=Le−Lμ−Lτ (LC, iv to golden ratio type A (GRA mixing, v to golden ratio type B (GRB mixing, and vi to hexagonal (HG mixing. Employing the minimal form of Ue, in terms of angles and phases it contains, that can provide the requisite corrections to Uν so that reactor, atmospheric and solar neutrino mixing angles θ13, θ23 and θ12 have values compatible with the current data, including a possible sizable deviation of θ23 from π/4, we discuss the possibility to obtain predictions for the CP violation phases in the neutrino mixing matrix. Considering the “standard ordering” of the 12 and the 23 rotations in Ue and following the approach developed in [1] we derive predictions for the Dirac phase δ and the rephasing invariant JCP in the cases of GRA, GRB and HG forms of Uν (results for the TBM and BM (LC forms were obtained in [1]. We show also that under rather general conditions within the scheme considered the values of the Majorana phases in the PMNS matrix can be predicted for each of the forms of Uν discussed. We give examples of these predictions and of their implications for neutrinoless double beta decay. In the GRA, GRB and HG cases, as in the TBM one, relatively large CP violation effects in neutrino oscillations are predicted (|JCP|∼(0.031–0.034. Distinguishing between the TBM, BM (LC, GRA, GRB and HG forms of Uν requires a measurement of cos⁡δ or a relatively high precision measurement of JCP.

    It has recently been shown that by measuring the transverse polarizations of the final particles in μ→eee, it is possible to extract information on the phases of the effective couplings leading to this decay. We examine this possibility within the context of R-parity violating Minimal Supersymmetric Standard Model (MSSM) in which the μ→eee process can take place at a tree level. We demonstrate how a combined analysis of the angular distribution of the emitted electrons and their transverse polarization can determine the CP-violating phases of the trilinear R-parity violating Yukawa couplings.

  17. Spontaneous $CP$ breaking in QCD and the axion potential: an effective Lagrangian approach arXiv

    CERN Document Server

    Di Vecchia, Paolo; Veneziano, Gabriele; Yankielowicz, Shimon

    Using the well-known low-energy effective Lagrangian of QCD --valid for small (non-vanishing) quark masses and a large number of colors-- we study in detail the regions of parameter space where $CP$ is spontaneously broken/unbroken for a vacuum angle $\\theta= \\pi$. In the $CP$-broken region there are first order phase transitions as one crosses $\\theta=\\pi$, while on the (hyper)surface separating the two regions, there are second order phase transitions signaled by the vanishing of the mass of a pseudo Nambu-Goldstone boson and by a divergent QCD topological susceptibility. The second order point sits at the end of a first order line associated with the $CP$ spontaneous breaking, in the appropriate complex parameter plane. When the effective Lagrangian is extended by the inclusion of an axion these features of QCD imply that standard calculations of the axion potential have to be revised when the QCD parameters fall in the above mentioned $CP$-broken region, in spite of the fact that the axion solves the stro...

    We study the effect from a fourth generation quark on penguin-dominated two-body nonleptonic B meson decays in the next-to-leading order perturbative QCD formalism. With an enhancement of the color-suppressed tree amplitude and possibility of a new CP phase in the electroweak penguin, we can account better for A_{CP}(B^0 -> K^+ pi^-)-A_{CP}(B^+ -> K^+ pi^0). Taking |V_{t's}V_{t'b}| \\sim 0.02 with phase just below 90^\\circ, which are consistent with the b -> s l^+ l^- rate and the B_s mixing parameter \\Delta m_{B_s}, we find a downward shift in the mixing-induced CP asymmetries of B^0 -> K_S pi^0 and phi K_S, but the predicted behavior for B^0 -> rho^0 K_S is opposite.

    If the baryon asymmetry of the Universe is produced by leptogenesis, CP violation is required in the lepton sector. In the seesaw extension of the standard model with three hierarchical right-handed neutrinos, we show that the baryon asymmetry is insensitive to the Pontecorvo-Maki-Nagakawa-Sakata phases: thermal leptogenesis can work for any value of the observable phases. This result was well known when there were no flavor effects in leptogenesis; we show that it remains true when flavor effects are included.

    Ballett, Peter; Turner, Jessica

    2015-01-01

    The observed leptonic mixing pattern could be explained by the presence of a discrete flavour symmetry broken into residual subgroups at low energies. In this scenario, a residual generalised CP symmetry allows the parameters of the PMNS matrix, including Majorana phases, to be predicted in terms of a small set of input parameters. In this article, we study the mixing parameter correlations arising from the symmetry group A5 including generalised CP subsequently broken into all of its possible residual symmetries. Focusing on those patterns which satisfy present experimental bounds, we then provide a detailed analysis of the measurable signatures accessible to the planned reactor, superbeam and neutrinoless double beta decay experiments. We also discuss the role which could be played by high-precision measurements from longer term projects such as the Neutrino Factory. This work provides a concrete example of how the synergies of the upcoming experimental programme allow flavour symmetric models to be thoroug...

    Generalised CP transformations are the only known framework which allows to predict Majorana phases in a flavour model purely from symmetry. For the first time generalised CP transformations are investigated for an infinite series of finite groups, Δ(6n{sup 2})=(Z{sub n}×Z{sub n})⋊S{sub 3}. In direct models the mixing angles and Dirac CP phase are solely predicted from symmetry. The Δ(6n{sup 2}) flavour symmetry provides many examples of viable predictions for mixing angles. For all groups the mixing matrix has a trimaximal middle column and the Dirac CP phase is 0 or π. The Majorana phases are predicted from residual flavour and CP symmetries where α{sub 21} can take several discrete values for each n and the Majorana phase α{sub 31} is a multiple of π. We discuss constraints on the groups and CP transformations from measurements of the neutrino mixing angles and from neutrinoless double-beta decay and find that predictions for mixing angles and all phases are accessible to experiments in the near future.

    2014-04-15

    On-line analytical techniques such as condensed phase membrane introduction mass spectrometry (CP-MIMS) permit direct and rapid analyte measurements in complex samples. Direct, rapid analytical methods are desirable because they eliminate potential contamination and/or dilution from sample workup steps, facilitate rapid sample screening and allow 'real-time' monitoring applications. PDMS hollow fibre membrane (HFM) flow cell interfaces (215 µm, 35 µm, and 0.5 µm thick composite) were coupled with an electrospray ionization (ESI) triple quadrupole mass spectrometer. A simultaneous push/pull methanol acceptor phase delivery system and membrane mounting via epoxy potting ensured that the delicate membranes were not ruptured during construction or sample measurements. Both flow cell and direct insertion 'J-Probe' interfaces using the 0.5 µm thick composite PDMS HFM were utilized for direct naphthenic acid measurements. Delicate HFM CP-MIMS interfaces were used for the rapid screening and continuous, on-line monitoring of carboxylic acids and hydroxylated compounds directly in complex sample matrices under ambient conditions at pptr - ppb detection limits. Push/pull acceptor phase (methanol) delivery maintained ambient hydrostatic pressures within the HFMs, improving ESI stability and analytical sensitivity, especially with stopped acceptor flow operation. Signal response times less than 2 min were achieved for thin, composite PDMS HFMs at 30°C. The continuous monitoring of naphthenic acid degradation was demonstrated. Delicate PDMS HFM CP-MIMS interfaces were developed and used for the direct, on-line detection of low volatility, polar analytes in complex aqueous samples. Composite PDMS HFM interfaces yielded the best overall analytical performance improvements, and were used to demonstrate the direct measurement of naphthenic acids in complex aqueous samples.

    The discovery of the Higgs boson by the LHC experiments ATLAS and CMS has marked a milestone for particle physics. Yet, there are still many open questions that cannot be answered within the Standard Model (SM). For example, the generation of the observed matter-antimatter asymmetry in the universe through baryogenesis can only be explained qualitatively in the SM. A simple extension of the SM compatible with the current theoretical and experimental constraints is given by the 2-Higgs-Doublet Model (2HDM) where a second Higgs doublet is added to the Higgs sector. We investigate the possibility of a strong first order electroweak phase transition in the CP-conserving 2HDM type I and type II where either of the CP-even Higgs bosons is identified with the SM-like Higgs boson. The renormalisation that we apply on the loop-corrected Higgs potential allows us to efficiently scan the 2HDM parameter space and simultaneously take into account all relevant theoretical and up-to-date experimental constraints. The 2HDM parameter regions found to be compatible with the applied constraints and a strong electroweak phase transition are analysed systematically. Our results show that there is a strong interplay between the requirement of a strong phase transition and collider phenomenology with testable implications for searches at the LHC.

  6. Comparison of analytical protein separation characteristics for three amine-based capillary-channeled polymer (C-CP) stationary phases.

    Capillary-channeled polymer (C-CP) fiber stationary phases are finding utility in the realms of protein analytics as well as downstream processing. We have recently described the modification of poly(ethylene terephthalate) (PET) C-CP fibers to affect amine-rich phases for the weak anion-exchange (WAX) separation of proteins. Polyethylenimine (PEI) is covalently coupled to the PET surface, with subsequent cross-linking imparted by treatment with 1,4-butanediol diglycidyl ether (BUDGE). These modifications yield vastly improved dynamic binding capacities over the unmodified fibers. We have also previously employed native (unmodified) nylon 6 C-CP fibers as weak anion/cation-exchange (mixed-mode) and hydrophobic interaction chromatography (HIC) phases for protein separations. Polyamide, nylon 6, consists of amide groups along the polymer backbone, with primary amines and carboxylic acid end groups. The analytical separation characteristics of these three amine-based C-CP fiber phases are compared here. Each of the C-CP fiber columns in this study was shown to be able to separate a bovine serum albumin/hemoglobin/lysozyme mixture at high mobile phase linear velocity (∼70 mm s(-1)) but with different elution characteristics. These differences reflect the types of protein-surface interactions that are occurring, based on the active group composition of the fiber surfaces. This study provides important fundamental understanding for the development of surface-modified C-CP fiber columns for protein separation.

    We study an effective field theory describing CP-violation in a scalar meson sector. We write the simplest interaction that we can imagine, $${\\cal L}\\sim \\epsilon_{i_1\\cdots i_5}\\epsilon^{\\mu_1\\cdots\\mu_4}\\phi_{i_1}\\partial_{\\mu_1}\\phi_{i_2}\\partial_{\\mu_2}\\phi_{i_3}\\partial_{\\mu_3}\\phi_{i_4}\\partial_{\\mu_4}\\phi_{i_5}$$ which involves 5 scalar fields. The theory describes CP-violation only when it contains scalar fields representing mesons such as the $K^*_0$, sigma, $f_0$ or $a_0$. If the fields represent pseudo-scalar mesons, such as B, K and $\\pi$ mesons then the Lagrangian describes anomalous processes such as $KK\\to \\pi\\pi\\pi$. We speculate that the field theory contains long lived excitations corresponding to $Q$-ball type domain walls expanding through space-time. In an 1+1 dimensional, analogous, field theory we find an exact, analytic solution corresponding to such solitons. The solitons have a U(1) charge $Q$, which can be arbitrarily high, but oddly, the energy behaves as $Q^{2/3}$ for large charg...

    The precision of the CP phases $2\\beta$ and $2\\beta_s$ determined from the mixing-induced CP asymmetries in $B_d\\to J/\\psi K_S$ and $B_s\\to J/\\psi \\phi$, respectively, is limited by the unknown long-distance contribution of a penguin diagram involving up quarks. We analyze the infrared QCD structure of this contribution and find that all soft and collinear divergences either cancel between different diagrams or factorize into matrix elements of local four-quark operators up to terms suppressed by $\\Lambda_{QCD}/m_{\\psi}$, where $m_{\\psi}$ denotes the $J/\\psi$ mass. Our results allow us to calculate the penguin-to-tree ratio $P/T$ in terms of the matrix elements of these operators and to constrain the penguin contribution to the phase $2\\beta$ as $|\\Delta \\phi_d|\\leq {0.68}^\\circ$. The penguin contribution to $2\\beta_s$ is bounded as $|\\Delta \\phi_s^{0}|\\leq {1.03}^\\circ$, $|\\Delta \\phi_s^{\\parallel}|\\leq {1.28}^\\circ$, and $|\\Delta \\phi_s^{\\perp}|\\leq {0.95}^\\circ$ for the case of longitudinal, parallel, and ...

    A first flavor-tagged measurement of the time-dependent $CP$-violating asymmetry in $B_s^0 \\to \\phi\\phi$ decays is presented. In this decay channel, the $CP$-violating weak phase arises due to $CP$ violation in the interference between $B_s^0$-$\\overline{B}_s^0$ mixing and the $b \\to s \\overline{s} s $ gluonic penguin decay amplitude. Using a sample of $pp$ collision data corresponding to an integrated luminosity of 1.0 fb$^{-1}$ and collected at a centre-of-mass energy of 7 TeV with the LHCb detector, $880\\ B_s^0 \\to \\phi \\phi$ signal decays are obtained. The $CP$-violating phase is measured to be in the interval [-2.46, -0.76 ] rad at 68% confidence level. The p-value of the Standard Model prediction is 16 %.

  10. Unraveling the CP phase of top-Higgs coupling in associated production at the LHC

    Full Text Available We study the sensitivity of top polarization observables to the CP phase ζt in the top Yukawa coupling in the process pp→thj at the 14 TeV high-luminosity run of the Large Hadron Collider (HL-LHC. We calculate the top polarization in this process as well as an azimuthal asymmetry of the charged lepton arising from the decay of the top in the lab frame. We find that the dependence of this lab-frame azimuthal asymmetry on the phase ζt closely resembles the dependence of the top polarization on ζt. As compared to the cross section, which is sensitive to ζt for larger values, the lepton azimuthal asymmetry can provide a sensitive measurement of ζt for smaller values.

Using CpG ODNs as an adjuvant has been found to be effective for treating infectious diseases, cancers, and allergies. Because natural ODNs with only a phosphodiester backbone are easily degraded by nuclease (deoxyribonuclease [DNase] in serum, CpG ODNs with a phosphorothioate backbone have been studied for clinical application. CpG ODNs with a phosphorothioate backbone have raised concern regarding undesirable side effects; however, several CpG ODNs with only a phosphodiester backbone have been reported to be stable in serum and to show an immunostimulatory effect. In recent years, research has been conducted on delivery systems for CpG ODNs using nanoparticles (NPs. The advantages of NP-based delivery of CpG ODN include (1 it can protect CpG ODN from DNase, (2 it can retain CpG ODN inside the body for a long period of time, (3 it can improve the cellular uptake efficiency of CpG ODN, and (4 it can deliver CpG ODN to the target tissues. Because the target cells of CpG ODN are cells of the immune system and TLR9, the receptor of CpG ODN is localized in endolysosomes, CpG ODN delivery systems are required to have qualities different from other nucleic acid drugs such as antisense DNA and small interfering RNA. Studies until now have reported various NPs as carriers for CpG ODN delivery. This review presents DNase-resistant CpG ODNs with various structures and their immunostimulatory effects and also focuses on delivery systems of CpG ODNs that utilize NPs. Because CpG ODNs interact with TLR9 and activate both the innate and the adaptive immune

    In this study, we proposed to modify mesoporous silica nanoparticles (MSNs) with 3-aminopropyltriethoxysilane (NH2-TES), aminoethylaminopropyltriethoxysilane (2NH2-TES) and 3-[2-(2-aminoethylamino)ethylamino] propyl-trimethoxysilane (3NH2-TES) for binding of cytosine-phosphate-guanosine oligodexynucleotides (CpG ODN), and investigated the effect of different amino groups of MSNs on the CpG ODN delivery. Serum stability, in vitro cytotoxicity, and cytokine interleukin-6 (IL-6) induction by MSN-NH2/CpG, MSN-2NH2/CpG and MSN-3NH2/CpG complexes were investigated in detail. The results showed that three kinds of aminated-MSN-based CpG ODN delivery systems had no cytotoxicity to RAW264.7 cells, and binding of CpG ODN to MSN-NH2, MSN-2NH2 and MSN-3NH2 nanoparticles enhanced the serum stability of CpG ODN due to protection by the nanoparticles. However, three aminated MSN-based CpG ODN delivery systems exhibited different CpG ODN delivery efficiency, and MSN-NH2/CpG complexes had the highest ability to induce IL-6 secretion.

    We consider a model based on A{sub 4} symmetry to explain the phenomenon of neutrino mixing. The spontaneous symmetry breaking of A{sub 4} symmetry leads to a co-bimaximal mixing matrix at leading order. We consider the effect of higher order corrections in neutrino sector and find that the mixing angles thus obtained, come well within the 3σ ranges of their experimental values. We study the implications of this formalism on the other phenomenological observables, such as CP violating phase, Jarlskog invariant and the effective Majorana mass vertical stroke M{sub ee} vertical stroke. We also obtain the branching ratio of the lepton flavour violating decay μ → eγ in the context of this model and find that it can be less than its present experimental upper bound. (orig.)

    The Standard Model of Partice Physics (SM) is probably the most successful theory, regarding to his predictions. The SM prediction for $CP$ violation is not enough to explain the overwhelming asymmetry among the matter and anti-matter abundance. Measuring some process where $CP$ violation is different to the one predicted by the SM would be a clear signal for Physics Beyond the Standard Model. The SM prediction for the $CP$ violation phase, $\\phi_{s}$, in the $B^{0}_{s}$ meson is practically equal to zero for the current experiments. This means that measuring a deviation from zero in $\\phi_{s}$ could be an indication for Physics Beyond the SM. On the other hand, the approximation based on the ``heavy quark symmetry'' let approximated calculations of the fundamental quantities of those hadrons containing a heavy quark, $c,b,t$. These calculations are expressed as expansions on inverse powers of the heavy quark mass in such hadron. This formalism is called `` Heavy Quark Effective Theory'' (HQET), and has been successful predicting some properties of the heavy hadrons. The HQET prediction for the lifetime ratio the $B^{0}_{d}$ and $B^{0}_{s}$ is practically equal to one. So, measuring with good precision the $B^{0}_{s}$ lifetime is also a way to test an approximation based on the SM. In this thesis it is detailed presented the method to measure the $\\phi_{s}$ and the lifetime ratio of the $B^{0}_{d}$ and $B^{0}_{s}$, among other quantities, with the DØ located in the Fermi National Accelerator Laboratory, in the United States.

    The measurement of the mixing-induced CP-violating phase $\\phi_s$ in the Bs-Bsbar system is one of the key goals of the LHCb experiment. It has been measured at LHCb exploiting the Run I data set and using several decay channels. The poster shows the most recent results obtained analyzing $B_s^0 \\to J/\\psi K^+K^-$ candidates in the mass region above the $\\phi(1020)$ resonance. The poster also shows previous measurements obtained analyzing the golden channel, $B_s^0 \\to J/\\psi K^+K^-$ in $\\phi(1020)$ region, and $B_s^0 \\to J/\\psi \\pi^+ \\pi^-$. Finally, a combination of those studies is presented.

    CP violation in the standard model originates from the Cabibbo-Kobayashi-Maskawa mixing matrix. Upon integrating all fermions out of the theory, its effects are captured by a series of effective nonrenormalizable operators for the bosonic gauge and Higgs fields. We compute the CP-violating part...

Its value is predicted to be very small in the Standard Model. However it can be significantly enhanced by contributions from effects of new physics.

Using a dataset corresponding to 3 fb$^{-1}$ collected at LHCb during 2011-2012 they are measured to be $\\phi_{s}=-0.010\\pm0.039$ rad and ${\\Delta\\Gamma_{s}}=0.0805\\pm0.0091\\pm0.0032$ ps$^{-1}$. $\\text {PACS numbers: 11.30.Hv, 13.20.Fc, 14.40.Lb}$

  20. Neutrino oscillograms of the Earth: effects of 1-2 mixing and CP-violation

    CERN Document Server

    Akhmedov, Evgeny Kh; Smirnov, Alexei Yu

    2008-01-01

    We develop a comprehensive description of three flavor neutrino oscillations inside the Earth in terms of neutrino oscillograms in the whole range of nadir angles and for energies above 0.1 GeV. The effects of the 1-2 mass splitting and mixing as well the interference of the 1-2 and 1-3 modes of oscillations are quantified. The 1-2 mass splitting and mixing lead to the appearance, apart from the resonance MSW peaks, of the parametric resonance peak for core-crossing trajectories at E_nu ~= 0.2 GeV. We show that the interference effects, in particular CP violation, have a domain structure with borders determined by the solar and atmospheric magic lines and the lines of the interference phase condition. The dependence of the oscillograms on the Dirac CP-violating phase is studied. We show that for sin^2(2 theta13) << 0.1 the strongest dependence of the oscillograms on delta is in the 1-2 and 1-3 resonance regions.

    We consider a scenario where, along with the usual Higgs doublet, two scalar triplets are present. The extension of the triplet sector is required for the Type~II mechanism for the generation of neutrino masses, if this mechanism has to generate a neutrino mass matrix with two-zero texture. One CP-violating phase has been retained in the scalar potential of the model, and all parameters have been chosen consistently with the observed neutrino mass and mixing patterns. We find that a large phase ($\\gtrsim 60^{\\circ}$) splits the two doubly-charged scalar mass eigenstates wider apart, so that the decay $H_1^{++} \\rightarrow H_2^{++} h$ is dominant (with h being the $125$ GeV scalar). We identify a set of benchmark points where this decay dominates. This is complementary to the situation, reported in our earlier work, where the heavier doubly-charged scalar decays as $H_1^{++} \\rightarrow H_2^+ W^+$. We point out the rather spectacular signal, ensuing from $H_1^{++} \\rightarrow H_2^{++} h$, in the form of Higgs ...

    CP-96,345 ((2S, 3S)-cis-2-(diphenylmethyl)-N-((2-methoxyphenyl)methyl)-1-azabicyclo(2.2.2)octan-3-amine) antagonism of substance P-stimulated salivation was investigated in pentobarbital-anesthetized rats. Administered either intraperitoneally or orally, CP-96,345 produced dose-dependent inhibition of the sialogogic response elicited by substance P but had no effect on acetylcholine-stimulated salivation. CP-96,345 produced concentration-dependent inhibition of ({sup 3}H)substance P binding to rat submaxillary gland membranes, with a median effective concentration of 34{plus minus}3.6 nM. These biological activities were confined to CP-96,345 in that the 2R, 3R enantiomer (CP-96,344) was without effect.

    Determination of the CP-violating phase $\\phi_s$ in $B_s^0 \\to J/\\psi\\, K^+K^-$ decays is one of the key goals of the LHCb experiment. Its value is predicted to be very small in the Standard Model but can be significantly enhanced in many other models. We present the most precise measurement of $\\phi_s$ to date and the first observation of a non-zero $\\Delta\\Gamma_s$ based upon 1~fb$^{-1}$ of data collected at LHCb during 2011. Also the measurement of $\\phi_s$ with the decay mode $B_s^0 \\to J/\\psi\\, \\pi^+\\pi^-$ and a combination of the $J/\\psi\\, K^+K^-$ and $J/\\psi\\, \\pi^+\\pi^-$ results are reported. Additionally we present first results from the measurement of the decay $B_s^0 \\to J/\\psi\\, \\overline{K^{\\ast\\,0}}$, which is potentially interesting for controlling currently neglected higher order corrections in $B_s^0 \\to J/\\psi\\, K^+K^-$.

  4. From CP Phases to Yukawa Textures: Maximal Yukawa Hierarchies in Minimal Seesaw Models

    2016-01-01

    The type-I seesaw mechanism involving only two right-handed neutrinos represents a minimal model to account for the observed masses and mixings in the Standard Model neutrino sector. This model features four real parameters that cannot be fully fixed by the current data: two CP-violating phases, delta and sigma, as well as one complex parameter, z, that is experimentally inaccessible at low energies. We perform a systematic scan of this model over the complex z plane, addressing the following question: Suppose delta and sigma should be measured at particular values in the future---what are then the conceivable maximal hierarchies in the neutrino Yukawa matrix that are still consistent with all observations? In this sense, our analysis generalizes previous studies of the type-I seesaw mechanism with two right-handed neutrinos that assume exact texture zeros in the neutrino Yukawa matrix. As we are able to demonstrate, relaxing the assumption of exact texture zeros, significantly enlarges the range of possible ...

    Unmethylated CpG oligodeoxynucleotides (ODN) bind to the Toll-like receptor 9, thus stimulating the immune system. To study the effects of systemic pretreatment with CpG ODN on dermal regeneration, C57BL6/J Tyr mice were treated with CpG or control ODN 6 days prior to implantation of a dorsal skinfold chamber and skin wounding. Wound epithelialization was analyzed by planimetric microscopy. On day 18, wound tissues were taken for (immuno)histochemical staining. CpG ODN increased epithelialization compared with control ODN treatment. Histological analysis revealed reduced capillary density, reduced wound cellularity, and reduced numbers of infiltrating leukocytes, as well as reduced F4/80-positive macrophages, but increased numbers of RELM-α-positive M2 macrophages after CpG ODN treatment, reflecting a better quality of wound healing on day 18 compared with control ODN treatment. Reverse transcription-polymerase chain reaction analysis of Toll-like receptor 9 showed the receptor expression on both fibroblasts and keratinocytes. Fibroblasts showed an increase of migration upon increasing dosages of CpG and not control ODN, reaching ∼50% of the response of basic fibroblast growth factor-exposed cells. Keratinocytes dose-dependently responded to both CpG and control ODN up to values found in keratinocyte growth factor-exposed cells. In summary, CpG ODN support late tissue-remodeling processes that contribute to resolution of inflammation and solid wounds during skin regeneration.

    We study the effect from a sequential fourth generation quark on penguin-dominated two-body nonleptonic B meson decays in the next-to-leading order perturbative QCD formalism. With an enhancement of the color-suppressed tree amplitude and possibility of a new CP phase in the electroweak penguin amplitude, we can account better for A(CP)(B(0)-->K+ pi-)-A(CP)(B+-->K+ pi0). Taking |V(t's)V(t'b)| approximately 0.02 with a phase just below 90 degrees, which is consistent with the b-->sl+ l- rate and the B(s) mixing parameter Deltam(B)(s), we find a downward shift in the mixing-induced CP asymmetries of B(0)-->K(S)(pi 0) and phi(K)(S). The predicted behavior for B(0)-->rho(0)(K)(S) is opposite.

  7. Effect of the assignment of ancestral CpG state on the estimation of nucleotide substitution rates in mammals

    2008-09-01

    Full Text Available Abstract Background Molecular evolutionary studies in mammals often estimate nucleotide substitution rates within and outside CpG dinucleotides separately. Frequently, in alignments of two sequences, the division of sites into CpG and non-CpG classes is based simply on the presence or absence of a CpG dinucleotide in either sequence, a procedure that we refer to as CpG/non-CpG assignment. Although it likely that this procedure is biased, it is generally assumed that the bias is negligible if species are very closely related. Results Using simulations of DNA sequence evolution we show that assignment of the ancestral CpG state based on the simple presence/absence of the CpG dinucleotide can seriously bias estimates of the substitution rate, because many true non-CpG changes are misassigned as CpG. Paradoxically, this bias is most severe between closely related species, because a minimum of two substitutions are required to misassign a true ancestral CpG site as non-CpG whereas only a single substitution is required to misassign a true ancestral non-CpG site as CpG in a two branch tree. We also show that CpG misassignment bias differentially affects fourfold degenerate and noncoding sites due to differences in base composition such that fourfold degenerate sites can appear to be evolving more slowly than noncoding sites. We demonstrate that the effects predicted by our simulations occur in a real evolutionary setting by comparing substitution rates estimated from human-chimp coding and intronic sequence using CpG/non-CpG assignment with estimates derived from a method that is largely free from bias. Conclusion Our study demonstrates that a common method of assigning sites into CpG and non CpG classes in pairwise alignments is seriously biased and recommends against the adoption of ad hoc methods of ancestral state assignment.

  8. Predictions for the Majorana CP violation phases in the neutrino mixing matrix and neutrinoless double beta decay

    We obtain predictions for the Majorana phases α21 / 2 and α31 / 2 of the 3 × 3 unitary neutrino mixing matrix U = Ue† Uν, Ue and Uν being the 3 × 3 unitary matrices resulting from the diagonalisation of the charged lepton and neutrino Majorana mass matrices, respectively. We focus on forms of Ue and Uν permitting to express α21 / 2 and α31 / 2 in terms of the Dirac phase δ and the three neutrino mixing angles of the standard parametrisation of U, and the angles and the two Majorana-like phases ξ21 / 2 and ξ31 / 2 present, in general, in Uν. The concrete forms of Uν considered are fixed by, or associated with, symmetries (tri-bimaximal, bimaximal, etc.), so that the angles in Uν are fixed. For each of these forms and forms of Ue that allow to reproduce the measured values of the three neutrino mixing angles θ12, θ23 and θ13, we derive predictions for phase differences (α21 / 2 -ξ21 / 2), (α31 / 2 -ξ31 / 2), etc., which are completely determined by the values of the mixing angles. We show that the requirement of generalised CP invariance of the neutrino Majorana mass term implies ξ21 = 0 or π and ξ31 = 0 or π. For these values of ξ21 and ξ31 and the best fit values of θ12, θ23 and θ13, we present predictions for the effective Majorana mass in neutrinoless double beta decay for both neutrino mass spectra with normal and inverted ordering.

    We suggest a specific semiclassical background field, the so called pure gauge sphaleron explosion, to evaluate the magnitude of the CP violation stemming from the standard phase of the CKM matrix. We use it to evaluate the matrix elements of some next-to-leading order effective CP-violating operators suggested in the literature. We also derive the scale dependence of the corresponding coefficients. Finally, we discuss the expected magnitude of the CP violation in the cold electroweak scenario.

  10. Measurement of the $\\textit{CP}$-violating phase $\\phi_s$ in $B_s^0\\rightarrow$J/$\\psi\\phi$ decays with the ATLAS detector

    In the Standard Model of particle physics, \\textit{CP} violation arises due to a single complex phase in the Cabibbo-Kobayashi-Maskawa (CKM) quark mixing matrix. Testing the validity of the CKM mechanism as the only source of $\\textit{CP}$ violation is one of the major experimental challenges in particle physics today. Precise measurement of the CKM parameters therefore constrains the Standard Model, and may reveal effects beyond the Standard Model. Measurement of the time-dependent decay rates of $B_s^0\\rightarrow J/\\psi \\phi$ provides a theoretically clean method for extracting $\\textit{CP}$-violating weak mixing phase $\\phi_s$. Standard Model predicts $\\phi_s$ to be very small and it is very well constrained, while in many new physics models large $\\phi_s$ values are expected. $B_s^0\\rightarrow J/\\psi \\phi$ decay channel is sensitive to the new physics contributions, and already small deviations in a measurement of $\\phi_s$ would be hints for the existence of the new particles. In this work, we present a m...

    The vacuum-free vibration liquid phase(VLP) diffusion-bonding of SiCp/ZL101A composites was investigated. The effects of vibration on the interface structure, the phase transformation and the tensile strength of bonded joints were examined. Experimental results show that the oxide film on the surface of the composites is a key factor affecting the tensile strength of boned joints. The distribution of the oxide layers at the interface changes from a continuous line to a discontinuous one during vibration. The tensile strength of the VLP diffusion-bonded joints increases with the vibration time, and is up to the maximum of 172 MPa when the vibration time is 30 s. The phase structure of the bond region changes from the Zn-Al-Cu hyper-eutectic (η+ (β+ η)+(β+η+ε)) phases to Al-rich Al-base solid solution (α-Al) with increasing the vibration time.

    Aim: To investigate the effects of CpG-oligodeoxynucleotide (CpG-ODN) on the formation of macrophage foam cells and related gene expression. Methods: A gene expression profile was examined by microarray techniques, and mRNA expression was detected by reverse transcriptase polymerase chain reaction (RTPCR). The cholesterol and cholesteryl ester contents of cells were determined by high performance liquid chromatography. Results: CD36, LPL, and Fcγ2b, which were related to lipid metabolism and the formation of macrophage foam cells, were upregulated after CpG-ODN stimulation. The mRNA expression related to the formation of foam cells was confirmed by semiquantitative RT-PCR. Moreover,histochemical analysis confirmed that lipid deposits inside cells increased after CpG-ODN treatment. However, using flow cytometry, we found that CpG-ODN had no effect on the expression of membrane receptors. Conclusion: CpG-ODN up-regulated the expression of genes in macrophage foam cell formation.

    Oligodeoxynucleotides (ODN) containing unmethylated CpG dinucleotides in contexts of unique sequence (CpG motifs) is active as adjuvant in induction of cellular and humoral immune responses in young mice. To date, there are only limited reports about effect of CpG ODN on immune responses against hepatitis B (HB) infection in aged mice. Our studies demonstrated there were significant increases in secreting of total anti-HB IgG, IgG1 and IgG2a, as well as of IL-12 and IFN-γ, when CpG ODNs were injected together with hepatitis B antigen in aged mice. Moreover, CpG ODN could stimulate proliferation of spleen lymphocytes in a dose-dependent manner. Taken together, the results we obtained indicate that the adding of CpG ODN into the vaccine antigen might be useful in development of more effective vaccination for inducing anti-HB virus responses in the elderly.

    Full Text Available Background: Lactobacillus gasseri CP2305 (CP2305 is a strain of Lactobacillus isolated from a stool sample from a healthy adult that showed beneficial effects on health as a paraprobiotic. In a previous study, we demonstrated that CP2305-fermented heat-treated milk modified gut functions more than artificially acidified sour milk. Thus, the regulatory activity of the former beverage was attributed to the inactivated CP2305 cells. Objective: The aim of this study was to elucidate the contribution of non-viable paraprobiotic CP2305 cells to regulating human gut functions. We thus conducted a randomized, placebo-controlled, double-blinded parallel group trial. Design: The trial included 118 healthy participants with relatively low or high stool frequencies. The test beverage was prepared by adding 1×1010 washed, heat-treated, and dried CP2305 cells directly to the placebo beverage. The participants ingested a bottle of the assigned beverage daily for 3 weeks and answered daily questionnaires about defecation and quality of life. Fecal samples were collected and the fecal characteristics, microbial metabolite contents of the feces and composition of fecal microbiota were evaluated. Results: The number of evacuations and the scores for fecal odors were significantly improved in the group that consumed the CP2305-containing beverage compared with those of the group that consumed the placebo (p=0.035 and p=0.040, respectively. Regarding the fecal contents of microbial metabolites, the level of fecal p-cresol was significantly decreased in the CP2305 group relative to that of the placebo group (p=0.013. The Bifidobacterium content of the intestinal microbiota was significantly increased in the CP2305 group relative to that of the placebo group (p<0.008, whereas the content of Clostridium cluster IV was significantly decreased (p<0.003. The parasympathetic nerve activity of the autonomic nervous system became dominant and the total power of autonomic

    We present a measurement of the CP-violating weak mixing phase ϕs using the decay Bs(0)→Ds(+)Ds(-) in a data sample corresponding to 3.0 fb(-1) of integrated luminosity collected with the LHCb detector in pp collisions at center-of-mass energies of 7 and 8 TeV. An analysis of the time evolution of the system, which does not use the constraint |λ|=1 to allow for the presence of CP violation in decay, yields ϕs=0.02±0.17(stat)±0.02(syst)  rad, |λ|=0.91(-0.15)(+0.18)(stat)±0.02(syst). This result is consistent with the standard model expectation.

  20. Searching for P- and CP- odd effects in heavy ion collisions

    In this thesis we study the possibility that QCD breaks parity at high temperatures and densities, a scenario that may be tested in heavy ion collisions. Analytical studies with effective models suggest that QCD may break parity in dense systems. Besides, P- and CP- odd bubbles may appear in a finite volume due to local large topological fluctuations in a hot medium. The last effect may be treated in a quasi-equilibrium description by means of a non-trivial axial chemical potential. We consider the 'two flavour' Nambu--Jona-Lasinio model in the presence of a vector and an axial external chemical potentials and study the phase structure of the model at zero temperature. These magnitudes could trigger a phase where parity could be broken in QCD. Analogies and differences with the expected behaviour in QCD are discussed besides the limitations of the model. We also consider the low energy realization of QCD in terms of mesons when an axial chemical potential is present. The eigenstates of strong interactions do ...

    We study CP asymmetries in two-body decays of bottom squarks into charginos and tops. These asymmetries probe the SUSY CP phases of the sbottom and the chargino sector in the Minimal Supersymmetric Standard Model. We identify the MSSM parameter space where the CP asymmetries are sizeable, and analyze the feasibility of their observation at the LHC. As a result, potentially detectable CP asymmetries in sbottom decays are found, which motivates further detailed experimental studies for probing the SUSY CP phases.

    High-throughput, automated analytical measurements are desirable in many analytical scenarios, as are rapid sample pre-screening techniques to identify 'positive' samples for subsequent measurements using more time-consuming conventional methodologies (e.g., liquid chromatography/mass spectrometry (LC/MS)). A miniature condensed-phase membrane introduction mass spectrometry (CP-MIMS) probe for the direct and continuous, on-line measurement of pharmaceuticals and environmental contaminants in small, complex samples is presented. A miniature polydimethylsiloxane hollow fibre membrane (PDMS-HFM) probe is coupled with an electrospray ionization (ESI) triple quadrupole mass spectrometer. Analytes are transported from the probe to the ESI source by a methanol acceptor phase. The probe can be autosampler mounted and directly inserted in small samples (≥400 μL) allowing continuous and simultaneous pptr-ppb level detection of target analytes (chlorophenols, triclosan, gemfibrozil, nonylphenol) in complex samples (artificial urine, beer, natural water, waste water, plant tissue). The probe has been characterized and optimized for acceptor phase flow rate, sample mixing and probe washing. Signal response times, detection limits and calibration data are given for selected ion monitoring (SIM) and tandem mass spectrometry (MS/MS) measurements of target analytes at trace levels. Comparisons with flow cell type CP-MIMS systems are given. Analyte depletion effects are evaluated for small samples (≥400 μL). On-line measurements in small volumes of complex samples, temporally resolved reaction monitoring and in situ/in vivo demonstrations are presented. The miniature CP-MIMS probe developed was successfully used for the direct, on-line detection of target analytes in small volumes (40 mL to 400 μL) of complex samples at pptr to low ppb levels. The probe can be readily automated as well as deployed for in situ/in vivo monitoring, including reaction monitoring, small sample

  4. Polymer Inclusion Membranes with Condensed Phase Membrane Introduction Mass Spectrometry (CP-MIMS): Improved Analytical Response Time and Sensitivity.

    Condensed phase membrane introduction mass spectrometry (CP-MIMS) is an online, in situ analysis technique for low volatility analytes. Analytes diffuse through a hollow fiber membrane, where they are then dissolved by a liquid (condensed) acceptor phase flowing through the membrane lumen. Permeating analytes are entrained to an atmospheric pressure ionization source for subsequent measurement by a mass spectrometer. Larger analytes, with inherently lower diffusivities, suffer from lengthy response times and lower sensitivity, limiting the use of CP-MIMS for their online, real-time measurement. We present the use of a heptane cosolvent in a methanol acceptor phase in combination with a polydimethylsiloxane (PDMS) membrane. The heptane generates an in situ polymer inclusion membrane (PIM) with the PDMS. We report improved measurement response times and greater sensitivity across a suite of analytes studied (gemfibrozil, nonylphenol, triclosan, 2,4,6-trichlorophenol, and naphthenic acids), with detection limits in the low parts per trillion (ppt) range. These improvements are attributed to increasing analyte diffusivities, as well as increased analyte partitioning across the PIM. Response times are ∼3× faster for the larger analytes studied, and calibration sensitivity is improved by up to ∼3.5× using 0.046 mole fraction heptane in the methanol acceptor. We report the use of short sample exposure times and the use of non-steady-state signals to reduce the analytical duty cycle, and illustrate that the use of a PIM provides a simple and robust variant of CP-MIMS amenable to rapid screening of analytes in complex samples.

    The surface of SiCP was Ti-coated via melt salt,and the Ti-coated SiCP/Al2014 composites were fabrica-ted by stir casting method.The effect law of size and volume fraction of Ti-coated SiCP on the microstructure and mechanical properties of SiCP/Al2014 composites were investigated.The results show that the Ti-coated processing could effectively improve the distribution uniformity of Ti-coated SiCP in Al matrix.When the size of Ti-coated SiCP keeps constant,the distribution uniformity of Ti-coated SiCP in Al matrix decreases with increasing volume fraction of SiCP .When volume fraction of SiCP keeps constant,the distribution uniformity of Ti-coated SiCP in Al matrix in-creases with increasing size of SiCP.When size of SiCP keeps constant,the tensile strength of SiCP/Al2014 compos-ites at room temperature increases first then decreases with increasing volume fraction of particles.The SiCP/Al2014 composites with 4% volume fraction of particles possess the highest tensile strength,i.e.,composites containing SiCP with sizes of 5μm and 10μm correspond to tensile strength of 524 MPa and 536 MPa,respectively.The tensile strength of SiCP/Al2014 composites at high temperature (493 K)increases with increasing volume fraction of SiCP. SiCP/Al composites with 6% volume fraction of particles possess the highest tensile strength.The composite with 5μm-SiCP exhibits tensile strength of 308 MPa while that with 10 μm-SiCP exhibits tensile strength of 320 MPa when the volume fraction of particles is 6%.%采用盐浴镀的方法对 SiCP 进行表面镀 Ti 处理,并通过搅拌铸造的方法制备了表面镀 Ti 改性 SiCP/Al2014复合材料。研究了镀Ti SiCP 的尺寸和体积分数对 SiCP/Al2014复合材料微观组织和力学性能的影响规律。结果表明:表面镀Ti处理能有效改善 SiCP 在 Al基体中的分散均匀性;但随着 SiCP 体积分数提高,相同尺寸的镀Ti SiCP 在Al基体分散均匀性逐渐变差,当SiCP 体积分数相同时,其

    To study the immune effect of CpGDNA on somatostatin (SS) DNA vaccine, the 20-day-old experimental mice were immunized with 20 μg SS eukaryotic expression plasmid pES/2SS with different adjuvants in equal dose, such as the synthetic CpG-ODN, the pE-CpG plasmid, E. coli DNA and the crude liposome. A booster was given two weeks later. The results showed that the body weight gain of female mice in the SS immunized group was higher than that of the control (P<0.05). The levels of antibodies against SS, IgG2a/IgG1, spleen lymphocyte proliferation activity and the concentrations of GH and IGF- Ⅰ in the DNA vaccine groups combined with CpGDNA were significantly increased compared to that of the group immunized with DNA vaccine alone. All these suggested the recombinant SS expression plasmid can stimulate animals to produce antibodies against SS, and CpGDNA adjuvant can enhance the immune effect of DNA vaccine against SS and influence the concentration of GH and IGF- Ⅰ.

  7. Determination of the CP-violating phase in $B_s^0 \\to J/\\psi\\phi$ decays at LHCb

    2010-01-01

    Flavour-tagged, time-dependent, angular analysis of the decay $B^0_s \\to J/\\psi \\phi$ allows the determination of a CP-violating phase which in the Standard Model is denoted $-2\\beta_s$, and is predicted to be very small. Many models of new physics lead to significant enhancements in the value of this observable. LHCb has the capability to improve significantly the existing experimental knowledge on this phase with the data expected in the 2010 run, and to probe down to the Standard Model prediction within a few years of operation. The steps in this measurement programme will be presented. Discussion will also be given to other methods to determine this phase, and related measurements in the $B^0_s$ sector.

    The peripubertal period appears to be critical in relation to the abuse of cannabinoids and opioids in humans. However there is little information about the acute effects of cannabinoids and their interactions with opioids in young experimental animals. We have studied the effects of the cannabinoid agonist CP 55,940 (0.1, 0.2, 0.4 and 0.6 mg/kg) on the nociceptive responses (tail immersion test) and holeboard activity of 40-day-old rats, and the involvement of the CB(1) receptor (antagonism by SR 141716A, 3 mg/kg). The implication of the opioid system was evaluated using the opioid antagonist naloxone (1 mg/kg) and a combined treatment with subeffective doses of CP 55,940 (0.1 mg/kg) and morphine (1 mg/kg). The effects of CP 55,940 on the serum corticosterone levels (radioimmunoassay) and on the dopamine and DOPAC contents of discrete brain regions (high-performance liquid chromatography) were also assessed. The antinociceptive effect of CP 55,940 was of a similar magnitude at all the doses used. The results show the involvement of the CB(1) receptor. The cannabinoid agonist significantly depressed the holeboard activity in a dose-dependent manner. The results indicate that the CB(1) receptor is involved in the effects on motor activity but not in the effects on the exploratory activity. The behavioural effects of CP 55,940 were modulated by morphine. The cannabinoid agonist (0.6 mg/kg) induced a CB(1)-mediated increase in the serum corticosterone levels, but no effect on the dopaminergic systems of either the striatum or the limbic forebrain was found.

    Measurement of the mixing-induced $CP$-violating phase $\\phi_s$ in $B^0_s$ decays is of prime importance in probing new physics. Here $7421 \\pm 105$ signal events from the dominantly $CP$-odd final state $J/\\psi\\pi^+\\pi^-$ are selected in 1 fb$^{-1}$ of $pp$ collision data collected at sqrt{s} = 7 TeV with the LHCb detector. A time-dependent fit to the data yields a value of $\\phi_s =-0.019^{+0.173+0.004}_{-0.174-0.003}$ rad, consistent with the Standard Model expectation. No evidence of direct $CP$ violation is found.

    We analyze the prospects of a feasible, very long baseline neutrino oscillation experiment consisting of a conventional horn produced low energy wide band beam and a detector of 500 kT fiducial mass with modest requirements on event recognition and resolution. Such an experiment is intended primarily to measure CP violating effects in the neutrino sector for 3-generation mixing. We analyze the sensitivity of such an experiment. We conclude that this experiment will allow determination of the CP parameter $\\delta_{CP}$, if the currently unknown mixing parameter $\\sin ^2 2 \\theta_{13} \\geq 0.01$, a value about 10 times lower than the present experimental upper limit. In addition to $\\theta_{13}$ and $\\delta_{CP}$, the experiment has great potential for precise measurements of most other parameters in the neutrino mixing matrix including $\\Delta m^2_{32}$, $\\sin^2 2\\theta_{23}$, $\\Delta m^2_{21}\\times \\sin^2 2 \\theta_{12}$, and the mass ordering of neutrinos through the observation of the matter effect in the $\\...

This study aimed to define the dose-effect relationship for CpG ODN 1826 in increasing radiosensitivity and its impact on immune function in a mouse model of Lewis lung cancer.Methods: The tumor-bearing mouse model was induced by injecting Lewis lung cancer cells into the right anterior leg subcutaneously. Sixty-four C57BL/6 J mice were evenly randomized into eight groups, comprising: a control group; an irradiation group; a CpG ODN 0.15 group; a CpG ODN 0.3 group; a CpG ODN 0.45 group; a CpG 0.15 + irradiation group; a CpG 0.3 + irradiation group; and a CpG 0.45 + irradiation group. Tumor growth, serum tumor necrosis factor-alpha and interleukin-12 concentrations, spleen and thymus exponents, and effect of CpG on the secondary immune response were measured, and apoptosis of tumor cells was investigated using TdT-mediated dUTP nick end labeling (TUNEL after treatment.Results: Tumor volumes in the treated groups were smaller than in the control group, with those of the CpG 0.45 + irradiation group being the smallest. TUNEL showed that the apoptosis rate in all the active treatment groups was higher than in the control group. CpG ODN apoptosis rate, serum tumor necrosis factor-alpha and interleukin-12 levels, and the spleen and thymus exponent showed greater improvement in the groups receiving combination therapy of CpG ODN and irradiation than the control group or the group receiving irradiation alone.

    The CP29 light harvesting complex from green plants is a pigment-protein complex believed to collect, conduct, and quench electronic excitation energy in photosynthesis. We have spectroscopically determined the relative angle between electronic transition dipole moments of its chlorophyll excitation energy transfer pairs in their local protein environments without relying on simulations or an X-ray crystal structure. To do so, we measure a basis set of polarized 2D electronic spectra and isolate their absorptive components on account of the tensor relation between the light polarization sequences used to obtain them. This broadly applicable advance further enhances the acuity of polarized 2D electronic spectroscopy and provides a general means to initiate or feed back on the structural modeling of electronically-coupled chromophores in condensed phase systems, tightening the inferred relations between the spatial and electronic landscapes of ultrafast energy flow. We also discuss the pigment composition of CP29 in the context of light harvesting, energy channeling, and photoprotection within photosystem II. PMID:21321222

    We combine the D0 measurement of the width difference between the light and heavy B_s^0 mass eigenstates and of the CP-violating mixing phase determined from the time-dependent angular distributions in the B_s -> J/psi phi decays along with the charge asymmetry in semileptonic decays also measured with the D0 detector. With the additional constraint from the world average of the flavor-specific B_s^0 lifetime, we obtain Delta Gamma_s = (\\Gamma_L - \\Gamma_H) = 0.13 +- 0.09 ps$^{-1}$ and phi_s = -0.70 ^{+0.47}_{-0.39}. The data sample corresponds to an integrated luminosity of 1.1 fb^{-1} accumulated with the D0 detector at the Fermilab Tevatron Collider.

    The perturbative treatment of subdominant oscillation and the matter effect in neutrino beams/superbeams, propagating over long baselines and being used to look for CP violation, is studied here for a general matter density function varying with distance. New lowest order analytic expressions are given for different flavour transition and survival probabilities in a general neutrino mixing basis and a variable earth matter density profile. It is demonstrated that the matter effect in the muon neutrino (antineutrino) flavour survival probability vanishes to this order, provided the depletion, observed for atmospheric muon neutrinos and antineutrinos at super-Kamiokande, is strictly maximal. This result is independent of the earth density profile and the distance L between the source and the detector. In the general variable density case we show that one cannot separate the matter induced asymmetry from a genuine CP effect by keeping two detectors at distances $L_1$ and $L_2$ from the source while maintaining a...

    The objective of this investigation is to study the effectiveness of anodized surface of commercial purity titanium (Cp-Ti) on its corrosion behaviour in simulated body fluid (SBF) and proliferation of osteoblast cells on it, to assess its potentiality as a process of surface modification in enhancing corrosion resistance and osseointegration of dental implants. Highly ordered nano-porous oxide layer, with nano-sized pores, is developed on the surface of Cp-Ti through electrochemical anodization in the electrolyte of aqueous solution of 0.5% HF at 15 V for 30 min at 24 °C. The nano-porous feature of the anodized surface is characterized by field-emission scanning electron microscope (FESEM). Pores of some anodized samples are sealed by exposing the anodized surface in boiling water. Corrosion behaviour of the anodized specimen is studied in Ringer’s solution at 30 ± 2 °C, using electrochemical impedance and cyclic polarization technique. Biocompatibility of the anodized surface is accessed using MG63 osteoblast cells. Both corrosion as well as pitting resistance of Cp-Ti in simulated body fluid are found to be highest in the anodized and sealed condition and followed in decreasing order by those of anodized and unanodized ones. Significantly higher MG63 osteoblast cell proliferations are found on the anodized surface than that on the unanodized one. Anodized Cp-Ti develops nano-size surface pores, like that of natural bone. It enhances corrosion and pitting resistance and also the process of osteoblast cell proliferation on Cp-Ti.

  17. New CP Violation in Neutrino Oscillations

    2001-01-01

    Measurements of CP-violating observables in neutrino oscillation experiments have been studied in the literature as a way to determine the CP-violating phase in the mixing matrix for leptons. Here we show that such observables also probe new neutrino interactions in the production or detection processes. Genuine CP violation and fake CP violation due to matter effects are sensitive to the imaginary and real parts of new couplings. The dependence of the CP asymmetry on source-detector distance is different from the standard one and, in particular, enhanced at short distances. We estimate that future neutrino factories will be able to probe in this way new interactions that are up to four orders of magnitude weaker than the weak interactions. We discuss the possible implications for models of new physics.

    Full Text Available Metal matrix composites (MMCs have emerged as an important class of materials, which are increasingly being utilized in recent years. These materials are known as the difficult-to-machine materials because of the hardness and abrasive nature of reinforcements. The present work investigate the effect of spindle speed, feed rate, depthof cut and different % wt. of SiCp on surface roughness in end milling of LM25Al/SiCp. Experiments have been conducted on a CNC milling machine according to the principles of Response surface methodology design of experiments (DoE method. Central composite design (CCD was employed in developing an efficient mathematical model for surface roughness. Analysis of variance (ANOVA was used to test the adequacy of the developed mathematical model. The contour plots were generated to study the effect of process parameters aswell as their interactions.

    CpG-oligodeoxynucleotides (CpG-ODN) are potent stimulators of the innate immune system. They promote a Th1-biased immune response with antineoplastic potential. We recently demonstrated antitumoral effects of CpG-ODN in murine transitional cell carcinoma (TCC) models. The purpose of the present work was to more precisely define the immunological nature of this immunotherapeutic approach to TCC.MB-49 TCC was established in female C57/Bl6 mice by intravesical tumor cell instillation after poly-L-lysine conditioning of the bladder (day 0) as described previously. Three groups of six mice were treated: intravesical instillation of 50 microl PBS on days 1, 3, 5, and 7 (group 1, untreated control); 10 nmol CpG 1668 on days 1, 3, 5, and 7 (group 2); and 10 nmol GpC 1668 on days 1, 3, 5, and 7 (group 3). Six native bladders served as no-treatment/no-tumor controls (group 4). Mice were sacrificed on day 11; bladders and draining lymph nodes were removed, and mRNA was prepared for quantitative real-time polymerase chain reaction. Samples were analyzed on a Bio-Rad iCycler for IL 10, TGF-beta, IL 12, and IFNgamma expression; threshold values were compared to beta-actin as housekeeping gene.Tumor take was 100%. Three animals in group 1 had to be sacrificed in advance due to rapid tumor progression. Relative cytokine expression was comparable in groups 1 and 4. IL-10, IL-12, TGF-beta, and IFNgamma were overexpressed in groups 2 and 3. CpG-ODN treatment of murine TCC results in overexpression of both classic Th1 cytokines (IL 12 and IFNgamma) and the Th2 marker IL 10. TGF-beta expression is increased as well. These phenomena are not induced by the growing TCC but by CpG-ODN therapy. They are accompanied by an objective clinical response, as we were able to show recently. Immunostimulatory DNA holds promise to be a novel therapeutic agent in TCC.

    Recently, studies on Aluminum Matrix Composite (AMC) were growing rapidly. AMC reinforced with SiCp particles in the semi solid stir casting method was the most simple way. In particular, the purpose of the present study was to investigate the effect composition of SiCp and TiB to the mechanical properties of the composites Al7Si-Mg-SiCp and Al7Si-Mg-TiB-SiCp. The composites used were Al7Si as the matrix and SiCp as the reinforcement (10, 15, 20 wt%). The casting method used on the study was the semi solid stir casting. The matrix was melted at the temperature of 800 °C. Then, the stirring process started at 590 °C with the speed of 500 rpm for 180 seconds. The composites was heated again until the pouring temperature was at 750 °C. The results of the present study indicated to be successful in which SiCp particles dispersed uniformly in the matrix composites. Further, the hardness value and porosity of the composites Al7Si-Mg-SiCp and Al7Si-Mg-TiB-SiCp increased along with the addition of TiB. Besides, the hardness value increased in the average of 10.5% at the variation of 20% SiCp. Whereas, the porosity value increased in the average of 54.3% at the variation of 20% SiCp.

    Using the fact that the neutrino mixing matrix U = U_{e}^{dagger} U_{ν}, where Ue and Uν result from the diagonalization of the charged lepton and neutrino mass matrices, we analyze the predictions based on the sum rules which the Dirac phase δ present in U satisfies when Uν has a form dictated by, or associated with, discrete favor symmetries and Ue has a "minimal" form (in terms of angles and phases it contains) that can provide the requisite corrections to Uν, so that the reactor, atmospheric and solar neutrino mixing angles θ13, θ23 and θ12 have values compatible with the current data.

    - anti-matter asymmetry in the universe of the order of O(10{sup -10}). Hence new sources of CP violation are required. One possible approach is CP violation in the supersymmetric extension of the Standard Model. The CP violation can be evoked in models with so-called 'minimal supergravity' (mSUGRA) by introducing a complex phase. In such models the lightest supersymmetric particle (LSP) is the neutralino one. The triple product of the final state in cascade decay chains with two- or three-body decays is sensitive for CP-violating effects. For this purpose the mass and momentum of all decay products must be known. The potential to observe CP violation in t cascade decay chains with the ATLAS detector is investigated, with the CP violation added to the trilinear coupling {phi}{sub A}. The momentum reconstruction of the neutralino one as well as the determination of the triple product asymmetry are presented. (orig.)

    One loop contributions to the CP even-CP odd Higgs boson mixings arising from contributions due to exchange of a vectorlike multiplet are computed under the Higgs boson mass constraint. The vectorlike multiplet consists of a fourth generation of quarks and a mirror generation. This sector brings in new CP phases which can be large consistent with EDM constraints. In this work we compute the contributions from the exchange of quarks and mirror quarks $t_{4L}, t_{4R}, T_{L}, T_{R}$, and their scalar partners, the squarks and the mirror squarks. The effect of their contributions to the Higgs boson masses and mixings are computed and analyzed. The possibility of measuring the effects of mixing of CP even and CP odd Higgs in experiment is discussed. It is shown that the branching ratios of the Higgs bosons into fermion pairs are sensitive to new physics and specifically to CP phases.

    Motivated by the possibility of the formation of CP-odd domains in heavy ion collisions, we investigate the effects of CP violation on the chiral transition within the linear sigma model with two flavors of quarks. We also study how the CP-odd system is affected by the presence of a strong magnetic field, that is presumably generated in a non-central heavy ion collision. We find that both ingredients play an important role, influencing drastically the nature of the phase transition and the critical temperature.

    In the supersymmetric model with local gauged baryon and lepton numbers (BLMSSM), the CP violating effects are considered to study the lepton electric dipole moment (EDM). The CP violating phases in BLMSSM are more than those in the standard model (SM) and can give large contributions. The analysis of the EDMs for the leptons e, μ, τ is shown in this work. It is in favour of exploring the source of CP violation and probing the physics beyond SM.

  11. Effect of CP violation in the singlet-doublet dark matter model

    2017-08-01

    Full Text Available We revisit the singlet-doublet dark matter model with a special emphasis on the effect of CP violation on the dark matter phenomenology. The CP violation in the dark sector induces a pseudoscalar interaction of a fermionic dark matter candidate with the SM Higgs boson. The pseudoscalar interaction helps the dark matter candidate evade the strong constraints from the dark matter direct detection experiments. We show that the model can explain the measured value of the dark matter density even if dark matter direct detection experiments do not observe any signal. We also show that the electron electric dipole moment is an important complement to the direct detection for testing this model. Its value is smaller than the current upper bound but within the reach of future experiments.

    We study a 3-3-1 model based on non-Abelian discrete symmetry group T{sub 13} which accommodates lepton mixing with non-zero θ{sub 13} and CP violation phase. The neutrinos get small masses and mixing with CP violation phase from S U(3) L antisextets which are all in triplets under T{sub 13}. If both breakings T{sub 13} → Z{sub 3} and Z{sub 3} → {Identity} are taken place in neutrino sector, and T{sub 13} is broken into Z{sub 3} in lepton sector, the realistic neutrino mixing form is obtained as a natural consequence of P{sub l} and T{sub 13} symmetries. The model predicts the lepton mixing with non-zero θ{sub 13}, and also gives a remarkable prediction of Dirac CP violation δ{sub CP} = 292.5∘ in the normal spectrum, and δ {sub CP} = 303.161∘ in the inverted spectrum which is still missing in the neutrino mixing matrix. There exist some regions of model parameters that can fit the experimental data in 2014 on neutrino masses and mixing without perturbation. (author)

    Full Text Available SiCp/Cu composites were successfully fabricated by vacuum hot-pressing method. Molybdenum coating was deposited on the surface of silicon carbide by sol-gel method. The effects of the interfacial design on thermo-physical properties of SiCp/Cu composites were studied. The results indicate that:continuous and uniform MoO3 coating can be deposited on the surface of silicon carbide by peroxomolybdic acid sol-gel system, and the best processing parameters are as follows:SiC:MoO3=5:1(mass ratio, H2O2:C2H5OH=1:1(volume ratio, and surface pretreatment with acetone and hydrofluoric acid is good to the deposition and growth of MoO3 coating. After hydrogen reduction at 540℃ for 90min the MoO3 is changed into MoO2, and then hydrogen reduction at 940℃ for 90min the MoO2 is changed into Mo absolutely, and the Mo coating is continuous and uniform. SiCp/Cu composites prepared by vacuum hot-pressing method show a compact and uniform microstructure, and the thermal conductivity of the composites is increased obviously after the Mo coating interfacial modification, which can reach 214.16W·m-1·K-1 when the volume of silicon carbide is about 50%.

    We derive predictions for the Dirac phase δ present in the 3 x 3 unitary neutrino mixing matrix U = U{sub e}{sup †}U{sub ν}, where U{sub e} and U{sub ν} are 3 x 3 unitary matrices which arise from the diagonalisation, respectively, of the charged lepton and the neutrino mass matrices. We consider forms of U{sub e} and U{sub ν} allowing us to express δ as a function of three neutrino mixing angles, present in U, and the angles contained in U{sub ν}. We consider several forms of U{sub ν} determined by, or associated with, symmetries, tri-bimaximal, bimaximal, etc., for which the angles in U{sub ν} are fixed. For each of these forms and forms of U{sub e} allowing one to reproduce the measured values of the neutrino mixing angles, we construct the likelihood function for cos δ, using (i) the latest results of the global fit analysis of neutrino oscillation data, and (ii) the prospective sensitivities on the neutrino mixing angles. Our results, in particular, confirm the conclusion, reached in earlier similar studies, that the measurement of the Dirac phase in the neutrino mixing matrix, together with an improvement of the precision on the mixing angles, can provide unique information as regards the possible existence of symmetry in the lepton sector.

    GSTP1 is induced by lead, and thus serves as a biomarker of lead exposure. Lead exposure changes DNA methylation status. We attempted to prove that the methylation of the GSTP1 promoter plays an important role in lead toxicity. We conducted a case-control study of 53 workers from a battery plant and 53 age and sex matched healthy volunteers to determine whether the methylation level of the GSTP1 promoter is associated with the risk of lead poisoning. We employed methylation-specific PCR (MSP) in cell models to determine the relationship between the GSTP1 methylation level and lead exposure. We found no association between GSTP1 methylation and lead exposure. The difference in methylation frequencies between the exposure group and the controls was not statistically significant (p = 0.401), and individuals with the methylated GSTP1 gene was not associated with the risk of lead poisoning (adjusted OR = 1.36, 95% CI, 0.22-8.24). This study suggests that GSTP1 methylation is not involved in the early phase of lead toxicity. Further studies should be performed to detect the association between GSTP1 methylation and the risk of lead poisoning in later phases.

    Measurement of mixing-induced $CP$ violation in $\\overline{B}^0_s$ decays is of prime importance in probing new physics. So far only the channel $\\overline{B}^0_s\\to J/\\psi\\phi$ has been used. Here we report on a measurement using an LHCb data sample of 0.41\\,fb$^{-1}$, in the $CP$ odd eigenstate $J/\\psi f_0(980)$, where $f_0(980)\\to\\pi^+\\pi^-$. A time dependent fit of the data with the $\\overline{B}^0_s$ lifetime and the difference in widths of the heavy and light eigenstates constrained to the values obtained from $\\overline{B}^0_s \\to J/\\psi\\phi$ yields a value of the $CP$ violating phase of $-0.44\\pm 0.44\\pm0.02~{\\rm\\,rad}$, consistent with the Standard Model expectation.

  3. Bs-B¯s mixing, CP violation, and extraction of CKM phases from untagged Bs data samples

    A width difference of the order of 20% has previously been predicted for the two mass eigenstates of the Bs meson. The dominant contributor to the width difference is b-->cc¯s transition, with final states common to both Bs and B¯s. All current experimental analyses fit the time dependences of flavor-specific Bs modes to a single exponential, which essentially determines the average Bs lifetime. We stress that the same data sample allows even the measurement of the width difference. To see that, this article reviews the time-dependent formulas for tagged Bs decays, which involve rapid oscillatory terms depending on Δ mt. In untagged data samples the rapid oscillatory terms cancel. Their time evolutions depend only on the much more slowly varying exponential falloffs. We discuss in detail the extraction of the two widths, and identify the large (small) CP-even (-odd) rate with that of the light (heavy) Bs mass eigenstate. It is demonstrated that decay length distributions of some untagged Bs modes, such as ρ0KS,ωKS,D(*)+/-sK(*)-/+, can be used to extract the notoriously difficult CKM unitarity triangle γ. Sizable CP-violating effects may be seen with such untagged Bs data samples. Listing ΔΓ as an observable allows for additional important standard model constraints. Within the CKM model, the ratio ΔΓ/Δm involves no CKM parameters, only a hadronic uncertainty. Thus a measurement of ΔΓ(Δm) would predict Δm(ΔΓ), up to the uncertainty. A large width difference would automatically solve the puzzle of the number of charmed hadrons per B decay in favor of theory. We also derive an upper limit of (||ΔΓ||/Γ)Bsf, and instead consider B(B0L(H)-->f), in analogy with the neutral kaons.

  4. Flavor origin of dark matter and its relation with leptonic nonzero θ 13 and Dirac CP phase δ

    We propose a minimal extension of the standard model by including a U(1) flavor symmetry to establish a correlation between the relic abundance of dark matter, measured by WMAP and PLANCK satellite experiments and non-zero value of sin θ 13 observed at DOUBLE CHOOZ, Daya Bay, RENO and T2K. The flavour symmetry is allowed to be broken at a high scale to a remnant {Z}_2 symmetry, which not only ensures the stability to the dark matter, but also gives rise to a modification to the existing A 4-based tri-bimaximal neutrino mixing. This deviation in turn suggests the required non-zero value of sin θ 13. We assume the dark matter to be neutral under the existing A 4 symmetry while charged under the U(1) flavor symmetry. Hence in this set-up, the non-zero value of sin θ 13 predicts the dark matter charge under U(1), which can be tested at various ongoing and future direct and collider dark matter search experiments. We also point out the involvement of nonzero leptonic CP phase δ, which plays an important role in the analysis.

    Trans-11 vaccenic acid [VA; 18:1(n-9)] is a positional and geometric isomer of oleic acid and is the precursor to conjugated linoleic acid (CLA) in humans. Despite VA being the predominant trans monoene in ruminant-derived lipids, very little is known about its nutritional bioactivity, particularly in conditions of chronic metabolic disorders, including obesity, insulin resistance, and/or dyslipidemia. The aim of this study was to assess the potential of VA to improve dyslipidemia, insulin sensitivity, or inflammatory status in obese and insulin-resistant JCR:LA-cp rats. The obese rats and age-matched lean littermates were fed a control diet or a control diet supplemented with 1.5% (wt:wt) VA for a period of 3 wk. The incorporation of VA and subsequent conversion to CLA in triglyceride was measured in adipose tissue. Glucose and insulin metabolism were assessed via a conscious adapted meal tolerance test procedure. Plasma lipids as well as serum inflammatory cytokine concentrations were measured by commercially available assays. VA supplementation did not result in any observable adverse health effects in either lean or obese JCR:LA-cp rats. After 3 wk of feeding, body weight, food intake, and glucose/insulin metabolism did not differ between VA-supplemented and control groups. The incorporation of VA and CLA into adipose triglycerides in obese rats fed VA increased by 1.5-fold and 6.5-fold, respectively, compared with obese rats fed the control diet. The most striking effect was a 40% decrease (P JCR:LA-cp rats. In contrast, dietary VA had substantial hypo-triglyceridemic effects, suggesting a new bioactivity of this fatty acid that is typically found in ruminant-derived food products.

    The perturbative treatment of subdominant oscillation and matter effect in neutrino beams/superbeams, propagating over long baselines and being used to look for CP violation, is studied here for a general matter density function varying with distance. New lowest order analytic expressions are given for different flavour transition and survival probabilities in a general neutrino mixing basis and a variable earth matter density profile. It is demonstrated that the matter effect in the muon neutrino (antineutrino) flavour survival probability vanishes to this order, provided the depletion, observed for atmospheric muon neutrinos and antineutrinos at super-Kamiokande, is strictly maximal. This result is independent of the earth density profile and the distance L between the source and the detector. In the general variable density case we show that one cannot separate the matter induced asymmetry from a genuine CP effect by keeping two detectors at distances L{sub 1} and L{sub 2} from the source while maintaining a fixed ratio L{sub 1}/E{sub 1}=L{sub 2}/E{sub 2}. This needs to be done numerically and we estimate the asymmetry generated by the earth matter effect with particular density profiles and some chosen parameters for very long baseline neutrino oscillation experiments.

  10. Measurement of the CP violating phase sin(2betas) using neutral B(s) meson going to J/psi phi decays at CDF

    Science.gov (United States)

    Pueschel, Elisa

    A B0s meson can oscillate into its anti-particle, the B¯0s meson, before decaying. CP violation in this system is made possible by the presence of amplitudes from both mixed and unmixed B0s meson decays. The CP violating phase beta s appears in the interference between the decay amplitudes. The quantity sin(2betas) is expected to be small in the standard model. Thus, measuring a large value for sin(2beta s) would be an unequivocal sign of new physics participation in the B0s mixing loop diagram. In this thesis, we present a latest measurement of sin(2beta s), using 5.2 fb--1 of data collected at CDF from pp¯ collisions at a center of mass energy of s = 1.96 TeV. A time-dependent angular analysis, with the production flavor of the B0s meson identified with flavor tagging methods, is used to extract sin(2beta s) from ˜6500 B0s → J/psiφ decays. Other parameters of interest, such as the B0s lifetime and the decay width difference DeltaGamma between the heavy and light B0s mass eigenstates are determined to high precision. Also, the effect of potential contributions to the final state from B0s → J/psif0 and B0s → J/psiK+K -- decays is considered for the first time. We present 68% and 95% confidence regions in the beta s -- DeltaGamma plane. The probability that the observed central value is a fluctuation of the data from the standard model expected value of betas is calculated to be 44%. The observed confidence region shows better agreement with the standard model prediction than previous measurements.

    Aim:DNAs containing unmethylated CpG motifs can stimulate innate and adaptive immunity.The aim of this study was to investigate the immunostimulatory and anti-neoplasm effects of a novel CpG oligodeoxynucleotide,ODN10,in tumor-bearing mice.Methods:B16 melanoma-bearing C57BL/6 mice were administered ip or sc with ODN10 or conventional CpG ODN1826 on the indicated days post inoculation.The animal survival rate and the inhibitory effect on tumor growth were observed in vivo.B and T lymphocyte proliferation,natural killing cell cytotoxicity and the phagocytic ability of peritoneal macrophages from the animals were determined using [3H]-thymidine incorporation assay,4-h 51Cr release assay and neutral red chromometry method,respectively.The serum levels of IL-12,IL-4,and IgE were quantified using ELISA assays.Histological examination of tumor tissues was performed after HE staining,and the expression of PCNA,CD63,and CD80 in tumor tissues was analyzed with immunohistochemistry.Results:ODN10 (1,5,and 25 mg/kg) significantly inhibited the growth and metastasis of the tumor,and significantly prolonged the survival of tumor-bearing mice,as compared with ODN1826,The immune status was suppressed in tumor-bearing mice.Both ODN10 and ODN1826 significantly reversed the suppressed immunoactivities in tumor-bearing mice,which included promoting B and T lymphocyte proliferation,enhancing NK cell and peritoneal macrophage activities,inducing IL-12 secretion and inhibiting IL-4 and IgE secretion.Further,CpG ODNs decreased PCNA and CD63 expression while induced expression of CD80.ODN10 presented more potent activity,and displayed the most prominent immunostimulatory potential.Conclusion:ODN10 produces prominent immunomodulatory effects on cellular immunity in tumor-bearing mice,which might help reverse the established Th2-type responses to the Th1-type responses,thus may be used as a potent anti-tumor immunotherapy agent or adjuvant.

    This lecture reviews the present status of CP violation in the Standard Model (SM) and some of its extensions and discuss ways to distinguish different models. More than 30 years have passed since the surprising discovery of CP violation in neutral kaon system in 1964, the origin of CP violation is still a mystery. Many models have been proposed to explain the observed CP violation in K{sup 0}-K-bar{sup 0} mixing. From previous discussions, it is clear that the SM is consistent with all laboratory experimental data. However there are also extensions of the SM such as the Weinberg Model and the Left-Right Symmetric Model, which can equally well explain experimental data. However, to date, no satisfactory explanation for CP violation has been established, therefore, more experiments are needed to pin down the origin of CP violation. Although no new signal for CP violation has been observed in laboratory systems, considerable progress have been made in obtaining limits on various experimental measurables, for example, the Electric Dipole Momentum`s of neutron and electron 107 refs., 20 figs.

    A large CP-violating phase uncovered recently by CDF and D$\\O$ collaborations in the time-dependent CP asymmetry (CPA) of the $B_s\\to J/\\Psi \\phi$ decay clearly indicates that a non-Cabibbo-Kobayashi-Maskawa (CKM) phase has to be brought into the $b\\to s$ transition. We find that the model with $SU(2)_L$ singlet exotic quarks can not only provide the new phase induced from the Z-mediated flavor changing neutral current (FCNC) at tree level, but also strongly relate the $B_s-\\bar B_s$ mixing, $B_q\\to V_q \\ell^{+} \\ell^{-}$ ($V_{d[s]}=K^*[\\phi])$ and $B_s\\to \\mu^{+} \\mu^{-}$ together. In particular, we show that the new CP phase can be unambiguously exposed by the large statistical significances of $T$ violating observables in $B_q\\to V_q \\ell^{+} \\ell^{-}$, while the branching ratio of $B_s\\to \\mu^{+} \\mu^{-}$ can be enhanced to be $O(10^{-8})$.

    Although CP violation was discovered more than thirty years ago, its origin is still unknown. In these lectures, we describe the CP-violating effects which have been seen in K decays, and explain how CP violation can be caused by the Standard Model weak interaction. The hypothesis that this interaction is indeed the origin of CP violation will be incisively tested by future experiments on B and K decays. We explain what quantities these experiments will try to determine, and how they will be able to determine them in a theoretically clean way. To clarify the physics of the K system, we give a phase-convention-free description of CP violation in this system. We conclude by briefly exploring whether electric dipole moments actually violate CP even if CPT invariance is not assumed.

    We consider a system of two-level quantum quasi-spins and gauge bosons put on a 3+1D lattice. As a model of neural network of the brain functions, these spins describe neurons quantum-mechanically, and the gauge bosons describes weights of synaptic connections. It is a generalization of the Hopfield model to a quantum network with dynamical synaptic weights. At the microscopic level, this system becomes a model of quantum brain dynamics proposed by Umezawa et al., where spins and gauge field describe water molecules and photons, respectively. We calculate the phase diagram of this system under quantum and thermal fluctuations, and find that there are three phases; confinement, Coulomb, and Higgs phases. Each phase is classified according to the ability to learn patterns and recall them. By comparing the phase diagram with that of classical networks, we discuss the effect of quantum fluctuations and thermal fluctuations (noises in signal propagations) on the brain functions.

    We develop codon-based models for simultaneously inferring the mutational effects of CpG and CpNpG methylation in coding regions. In a data set of 369 tomato genes, we show that there is very little effect of CpNpG methylation but a strong effect of CpG methylation affecting almost all genes. We...... further show that the CpNpG and CpG effects are largely uncorrelated. Our results suggest different roles of CpG and CpNpG methylation, with CpNpG methylation possibly playing a specialized role in defense against transposons and RNA viruses....

    We tested the hypothesis that aging and insulin resistance interact to increase vascular dysfunction by comparing the function of isolated mesenteric resistance arteries in obese, insulin-resistant JCR:LA-cp rats and lean, insulin-sensitive rats of the same strain at 3, 6, 9, and 12 mo of age. The peak constrictor responses to norepinephrine, phenylephrine, and high potassium were elevated in arteries from obese rats. Responses to these agents increased with age in both obese and lean rats. An eicosanoid constrictor contributed substantially to vasoconstriction in the arteries from both lean and obese animals. Inhibition of nitric oxide synthase increased the vasoconstrictor response to norepinephrine in both obese and lean rats. This effect increased with age in lean rats only. Vascular relaxation in response to acetylcholine and sodium nitroprusside was impaired in the obese rats and did not alter with age. The results suggest that obese JCR:LA-cp rats have enhanced maximal constriction, which originates in the arterial smooth muscle and increases with age. There is evidence that the ability of the arteries to compensate for the enhanced contractility is impaired in obese rats, particularly with advanced age.

    The charmless decays B± → K+ K- π± and B± → π+ π- π± are reconstructed in a data set of pp collisions with an integrated luminosity of 1.0  fb(-1) and center-of-mass energy of 7 TeV, collected by LHCb in 2011. The inclusive charge asymmetries of these modes are measured to be A(CP)(B± → K+ K- π±) = -0.141±0.040  (stat)±0.018 (syst)±0.007(J/ψ K±) and A(CP)(B± → π+ π- π±) = 0.117±0.021 (stat)±0.009 (syst)±0.007(J/ψ K±), where the third uncertainty is due to the CP asymmetry of the B± → J/ψK± reference mode. In addition to the inclusive CP asymmetries, larger asymmetries are observed in localized regions of phase space.

  1. Search for CP violation in the phase space of D0→π+π−π+π− decays

    Full Text Available A search for time-integrated CP violation in the Cabibbo-suppressed decay D0→π+π−π+π− is performed using an unbinned, model-independent technique known as the energy test. This is the first application of the energy test in four-body decays. The search is performed for P-even CP asymmetries and, for the first time, is extended to probe the P-odd case. Using proton–proton collision data corresponding to an integrated luminosity of 3.0 fb−1 collected by the LHCb detector at centre-of-mass energies of s=7 TeV and 8 TeV, the world's best sensitivity to CP violation in this decay is obtained. The data are found to be consistent with the hypothesis of CP symmetry with a p-value of (4.6±0.5% in the P-even case, and marginally consistent with a p-value of (0.6±0.2% in the P-odd case, corresponding to a significance for CP non-conservation of 2.7 standard deviations.

    SUSY CP problem in the gauge mediation supersymmetry breaking model is reconsidered. We pay particular attention to two sources of CP violating phases whose effects were not seriously studied before; one is the effect of the breaking of the GUT relation among the gaugino masses due to the field responsible for the GUT symmetry breaking, and the other is the supergravity effect on the supersymmetry breaking parameters, in particular, on the bi-linear supersymmetry breaking Higgs mass term. We show that both of them can induce too large electric dipole moments of electron, neutron, and so on, to be consistent with the experimental bounds.

  3. New ambiguity in probing CP violation in neutrino oscillations

    Miranda, O G; Valle, J W F

    2016-01-01

    If neutrinos get mass a la seesaw the mixing matrix describing neutrino oscillations can be effectively non-unitary. We show that in this case the neutrino appearance probabilities involve a new CP phase, phi, associated to non-unitarity. This leads to an ambiguity in extracting the "standard" three--neutrino phase delta_CP, which can survive even after neutrino and antineutrino channels are combined. Its existence should be taken into account in the planning of any oscillation experiment aiming at a robust measurement of delta_CP.

    Radioimmunotherapy (RIT) for relapsed indolent non-Hodgkin lymphoma produces overall response rates (ORR) of 80% with mostly partial remissions. Synthetic CpG oligonucleotides change the phenotype of malignant B-cells, are immunostimulatory, and can produce responses when injected intratumorally and combined with conventional radiation. In this phase I trial, we tested systemic administration of both CpG and RIT. Eligible patients had biopsy-proven previously treated CD20+ B-cell NHL and met criteria for RIT. Patients received rituximab 250 mg/m(2) days 1,8, and 15; (111) In-ibritumomab tiuxetan days 1, 8; CpG 7909 days 6, 13, 20, 27; and 0.4 mCi/kg of (90) Y-ibritumomab tiuxetan day 15. The doses of CpG 7909 tested were 0.08, 0.16, 0.32 (six patients each) and 0.48 mg/kg (12 patients) IV over 2 hr without dose limiting toxicity. The ORR was 93% (28/30) with 63% (19/30) complete remission (CR); median progression free survival of 42.7 months (95% CI 18-NR); and median duration of response (DR) of 35 months (4.6-76+). Correlative studies demonstrated a decrease in IL10 and TNFα, and an increase in IL1β, in response to therapy. CpG 7909 at a dose of 0.48 mg/kg is safe with standard RIT and produces a high CR rate and long DR; these results warrant confirmation.

  5. Lepton Mixing and CP Violation Phase in the 3-3-1 Model with Neutral Leptons Based on T 13 Flavor Symmetry

    We study a 3-3-1 model based on non-Abelian discrete symmetry group T 13 which accommodates lepton mixing with non-zero θ 13 and CP violation phase. The neutrinos get small masses and mixing with CP violation phase from S U(3) L antisextets which are all in triplets under T 13. If both breakings T 13 → Z 3 and Z 3 → {Identity} are taken place in neutrino sector, and T 13 is broken into Z 3 in lepton sector, the realistic neutrino mixing form is obtained as a natural consequence of P l and T 13 symmetries. The model predicts the lepton mixing with non-zero θ 13, and also gives a remarkable prediction of Dirac CP violation δ C P = 292.5∘ in the normal spectrum, and δ C P = 303.161∘ in the inverted spectrum which is still missing in the neutrino mixing matrix. There exist some regions of model parameters that can fit the experimental data in 2014 on neutrino masses and mixing without perturbation.

This result is in agreement with the standard model expectation at the level of about one Gaussian standard deviation. We consider the inclusion of a potential $S$-wave contribution to the $\\Bs\\to J/\\psi K^+K^-$ final state which is found to be negligible over the mass interval $1.009 < m(K^+K^-)<1.028 \\gevcc$.

    We present a measurement of the $CP$-violating weak mixing phase $\\phi_s$ using the decay $\\bar{B}^{0}_{s}\\to D_{s}^{+}D_{s}^{-}$ in a data sample corresponding to $3.0$ fb$^{-1}$ of integrated luminosity collected with the LHCb detector in $pp$ collisions at centre-of-mass energies of 7 and 8 TeV. An analysis of the time evolution of the system, which does not constrain $|\\lambda|=1$ to allow for the presence of $CP$ violation in decay, yields $\\phi_s = 0.02 \\pm 0.17$ (stat) $\\pm 0.02$ (syst) rad, $|\\lambda| = 0.91^{+0.18}_{-0.15}$ (stat) $\\pm0.02$ (syst). This result is consistent with the Standard Model expectation.

    de Oliveira, R L N; de Holanda, P C

    2014-01-01

    We use the open quantum systems framework to analyze the MINOS data and perform this analysis considering two different dissipative models. In the first model, the dissipative parameter describes decoherence effect and in the second, the dissipative parameter describes other dissipative effects including decoherence. With the second model it is possible to study CP violation since we consider Majorana neutrinos. The analysis from the muon neutrino and antineutrino beam assigns different values to all the parameters of the models, but consistent with each other. Assuming that neutrinos are equivalent to antineutrinos, the global analysis presents nonvanishing Majorana CP phase depending on the energetic parameterization of the dissipative parameter.

    Objective To explore the effects of CRF acceptor 1 (CRF - R1) antagonist CP - 154,526 (CP) and Ca2+ pathway antagonist verapamil ( VP) on plasma CRF secreting levels in the young rats after hypoxic - ischemia (HI) and after the rats were placed for one day. Methods Eighty young rats were randomly divided into eight groups,which were the control groups,sham operated groups,CP control groups, VP control groups,model groups ( HI groups) ,HI + CP groups,HI + VP groups and HI + CP + VP groups. Plasma CRF levels of the young rats in all groups were measured by radioimmunoassay. Results Compared with the control groups, plasma CRF levels in the HI groups, HI + CP groups and HI + CP + VP groups all significantly decreased ( P < 0. 001, P < 0. 001, P < 0. 001). Compared with the sham operated groups, plasma CRF levels in the HI groups, HI + CP groups and HI + CP + VP groups all significantly decreased (P < 0. 001 ,P <0. 001 ,P <0. 001) . Compared with the CP control groups,plasma CRF levels in the HI groups,HI + CP groups and HI + CP + VP groups all significantly decreased (P <0.001 ,P <0. 001 ,P <0.001). Compared with the VP control groups,plasma CRF levels in the HI groups,HI + CP groups and HI + CP + VP groups all significantly decreased (P <0. 001 ,P <0. 001 ,P <0.001). Compared with the HI groups,plasma CRF levels in the HI + CP groups and HI + VP groups all significantly increased ( P < 0. 05 , P < 0. 001) . Compared with the HI + CP groups,plasma CRF levels in the HI + VP groups significantly increased (P <0. 001). Compared with the HI + VP groups, plasma CRF levels in the HI + CP + VP groups significantly decreased ( P < 0.001 ) . Conclusion Plasma CRF levels in the young rats after HI and after the young rats were placed for one day significantly decreased. But,after the young rats were pretreated with CP or VP,the decrease of plasma CRF secreting levels under HI can be inversed. After the young rats were simultaneously pretreated with CP and VP,the decrease of

    A B0 s meson can oscillate into its anti-particle, the $\\bar{B}$0 s meson, before decaying. CP violation in this system is made possible by the presence of amplitudes from both mixed and unmixed B0 s meson decays. The CP violating phase βs appears in the interference between the decay amplitudes. The quantity sin(2βs) is expected to be small in the standard model. Thus, measuring a large value for sin(2βs) would be an unequivocal sign of new physics participation in the B0 s mixing loop diagram. In this thesis, we present a latest measurement of sin(2βs), using 5.2 fb-1 of data collected at CDF from p$\\bar{p}$ collisions at a center of mass energy of √s=1.96 TeV. A time-dependent angular analysis, with the production flavor of the B0 s meson identified with flavor tagging methods, is used to extract sin(2βs) from ~6500 B0 s→ J/ψφ decays. Other parameters of interest, such as the B0 s lifetime and the decay width difference between the heavy and light B0 s mass eigenstates are determined to high precision. Also, the effect of potential contributions to the final state from B0 s → J/ψf0 and B0 s→ J/ψK+K- decays is considered for the first time. We present 68% and 95% confidence regions in the βs plane. The probability that the observed central value is a fluctuation of the data from the standard model expected value of βs is calculated to be 44%. The observed confidence region shows better agreement with the standard model prediction than previous measurements.

    In the context of remnant CP transformations, I briefly discuss a generalized $\\mu-\\tau$ reflection symmetry, where the "Majorana" phases have CP conserving values, which are directly related with the CP parities of neutrino states. Also, one finds that the "Dirac-like" CP violation phase is correlated with the atmospheric mixing angle, giving important phenomenological implications for current and future long baseline oscillation neutrino experiments.

As the CP-odd observable, we use the asymmetry composed by triple products of final state momenta. There are good prospects of observing these effects using the method of kinematic reconstruction for the final and intermediate state particles. We also discuss the main experimental factors and the expected sensitivity.

If two or more modes are studied, {gamma} may be extracted with a precision on the order of {+-}15{sup o} given {approx}10{sup 8} B-mesons. We also discuss the case of three body decays of the D where additional information may be obtained from the distribution of the D decay products and consider the impact of D{bar D} oscillations.

It is found that choosing final states which are not CP eigenstates can lead to large direct CP violation which can give significant bounds on gamma without any theoretical assumptions. If two or more modes are studied, gamma may be extracted with a precision on the order of +/-15 degrees given about 10^8 B-mesons. We also discuss the case of three body decays of the D0 where additional information may be obtained from the distribution of the D0 decay products and consider the impact of D-D-bar oscillations.

    The compact oxide on the surface of SiCp/Al metal matrix composite (SiCp/Al MMC) greatly depends on the property of the joint. Inlaid sputtering target was applied to etch the oxide completely on the bonding surface of SiCp/Al MMC by plasma erosion. Cu/Ni/Cu film of 5 μm in thickness was prepared by magnetron sputtering method on the clean bonding surface in the same vacuum chamber, which was acted as an interlayer in transient liquid phase (TLP) bonding process. Compared with the same thickness of single Cu foil and Ni foil interlayer,the shear strength of 200 MPa was obtained using Cu/Ni/Cu film interlayer during TLP bonding, which was 89.7% that of base metal. In addition, homogenization of the bonding region and no particle segregation in interfacial region were found by analysis of the joint microstructure. Scanning electron microscopy (SEM) was used to observe the micrograph of the joint interface. The result shows that a homogenous microstructure of joint was achieved, which is similar with that of based metal.

    Quantum eigenstates undergoing cyclic changes acquire a phase factor of geometric origin. This phase, known as the Berry phase, or the geometric phase, has found applications in a wide range of disciplines throughout physics, including atomic and molecular physics, condensed matter physics, optics, and classical dynamics. In this article, the basic theory of the geometric phase is presented along with a number of representative applications. The article begins with an account of the geometric phase for cyclic adiabatic evolutions. An elementary derivation is given along with a worked example for two-state systems. The implications of time-reversal are explained, as is the fundamental connection between the geometric phase and energy level degeneracies. We also discuss methods of experimental observation. A brief account is given of geometric magnetism; this is a Lorenz-like force of geometric origin which appears in the dynamics of slow systems coupled to fast ones.

    In this paper zero modes of fluctuation are dissected around the two species of BPS vortices existing in the critical Higgs phase, where the scalar and vector meson masses are equal, of a gauged $\\mathbb{U}(1)$ nonlinear $\\mathbb{CP}^1$-model. If $2\\pi n$, $n\\in \\mathbb{Z}$, is the quantized magnetic flux of the two species of BPS vortex solutions, $2n$ linearly independent vortex zero modes for each species are found and described. The existence of two species of moduli spaces of dimension $2n$ of these stringy topological defects is thus locally shown.

    We have studied mixing and masses of three left handed Majorana neutrinos in the model, which assumes exactly degenerate neutrino masses at some "neutrino unification" scale. Such a simple theoretical ansatz naturally leads to quasidegenerate neutrinos. The neutrino mass splittings induced by renormalization effects. In the model we found that the parameters of the neutrino physics (neutrino mass spectrum, mixing angles and CP violation phases) are strongly intercorrelated to each other. From these correlations we got strong bounds on the parameters which could be checked in the oscillation experiments.

    The objective of this study was to develop a method to reliably and reproducibly assess the physical properties of in vitro multi-species plaque derived biofilms. A custom flow cell (FC) was designed to model oral cavity shear stresses on biofilms grown on hydroxyapatite (HA) discs. A finite-element program (ANSYS 13) modeled flow velocities and wall shear stresses on the interior 3D dimensions. For the experiment, 1% chlorhexidine (CHX), 5 M urea, and a 1× phosphate-buffered saline (PBS) were flown through the FC simulating oral rinsing. Near infrared cross-polarization optical coherence tomography (CP-OCT) non-destructively imaged the fluid immersed biofilms in real time (20 frames/s). During low flow, the swell of the biofilm caused from 5 M urea was quite pronounced increase in vertical dimension. Biofilms exposed to 1% CHX showed a slight collapse in the vertical dimension of the biofilm during low flow. During high flow/high sheer stress, the 5 M urea solution effectively removed the biofilm, while both 1% CHX and 1× PBS did not remove biofilms even under high velocity/shear stress conditions.

    采用粉末冶金法制备SiCp/2009Al复合材料热压锭,并对热压锭进行了热挤压,分析了热压态和挤压态复合材料的相组成和元素分布.结果表明:热压锭存在轻微的元素偏析,下部Cu和Mg含量略高于上部.热压态复合材料组成相主要为Al,SiC,Al2Cu和Mg2Si,另外还含有少量的Al7Cu2Fe和Mg的氧化物.经固溶处理后,Al2Cu和Mg2Si溶解,Cu在基体中均匀分布,但Mg仍偏聚于原始铝颗粒边界和SiC团聚处.挤压变形不改变复合材料的相组成,但使SiC分布更均匀并破碎了铝颗粒表面的氧化膜.挤压态复合材料经固溶处理后,Cu和Mg均在基体中均实现了均匀分布.%SiCp/2009Al composites were fabricated through powder metallurgy and subsequent extrusion. The phases and elemental distributions in the hot pressed and extruded composites were studied. The slight macro-segregation was found in the hot pressed composite billet. The concentrations of Cu and Mg in the bottom of the billet are somewhat higher than those in the top of the billet. The hot pressed composite contains Al, SiC, Al2Cu, Mg2Si and a small quantity of Al7Cu2Fe and oxide of Mg. After solid solution treatment, Al2Cu and Mg2Si dissolved into the matrix and Cu was distributed uniformly in the matrix. However, Mg was still preferentially distributed near the boundaries of the Al particles and in the clusters of SiC. No change of the phases types in the composites was found, however, the extrusion resulted in uniformly distribution of the SiC particles and broke up the oxide shell of the initial Al particles, thus Cu and Mg were distributed homogeneously in the extruded composites after solid solution treatment.

    Abstract:We study the conditions of maximal CP violation in the neutral Higgs mass matrix of the two Higgs doublet model. We get fixed values of \\tan\\b and constraints on the Higgs potential parameters. Two neutral Higgs scalars are constrained to be lighter than the charged Higgs scalar and these two Higgs scalars are expected to be almost degenerate due to the smallness of the h parameter, where h is the CP violating coupling constant of the Higgs interaction. The radiative correction of the \\rho parameter from the Higgs scalar exchange is rather small and its sign negative for a wide range of Higgs masses. It follows that maximum CP violation in the two Higgs doublet model is safely allowed for the \\rho parameter without the custodial symmetry.

    We study the elastic scattering of the lightest neutralino with a nucleus in the framework of the minimal supersymmetric standard model (MSSM) with explicit flavor preserving CP violation, including the one-loop CP-violating neutral Higgs-boson mixing effects induced dominantly by the CP phases in the top and bottom (s)quark sectors. We construct the most general form of the effective Lagrangian for the neutralino-nucleus scattering in the limit of vanishing momentum transfers and then we perform a comprehensive analysis of the effects of the complex CP phases on the mass spectra of the lightest neutralino, neutral Higgs bosons and top squarks, and on the the spin-dependent and spin-independent neutralino-nucleus scattering cross section for three neucleus targets F, Si and Ge. The CP phases can reduce or enhance the neutralino-nucleus cross sections significantly, depending on the values of the real parameters in the MSSM.

    S15261, a compound developed for the oral treatment of type II diabetes, is cleaved by esterases to the fragments Y415 and S15511. The aim was to define the insulin-sensitizing effects of S15261, the cleavage products, and troglitazone and metformin in the JCR:LA-cp rat, an animal model of the obesity/insulin resistance syndrome that exhibits an associated vasculopathy and cardiovascular disease. Treatment of the animals from 8 to 12 weeks of age with S15261 or S15511 resulted in reductions in food intake and body weights, whereas Y415 had no effect. Troglitazone caused a small increase in food intake (P JCR:LA-cp rat. S15261 may thus offer effective treatment for the insulin resistance syndrome and its associated vascular complications.

Methods: In vitro A549 cells were randomly separated into control, CpG, X-ray, CpG+X-ray, ATM kinase-small interfering RNA (siRNA+CpG+X-ray (ATM-siRNA, and Chk2-siRNA+CpG+X-ray (Chk2-siRNA groups. siRNAs were adopted to silence the ATM and Chk2 genes. Expression and phosphorylation of ATM kinase and Chk2 were detected by Western blot assay. Cell colonies were observed under inverted phase-contrast microscopy. Cellular survival curves were fitted using a multi-target single-hitting model. Cell cycle and apoptosis were analyzed by flow cytometry. Results: Expression of ATM kinase and Chk2 was similar among the control, CpG, X-ray, and CpG+X-ray groups. Phosphorylated ATM kinase and Chk2 were significantly increased in the CpG+X-ray group compared with in the X-ray group (t=6.00, P<0.01 and t=3.13, P<0.05, respectively, though these were hardly detected in the control and CpG groups. However, expression of ATM kinase and Chk2 was clearly downregulated in the ATM-siRNA and Chk2-siRNA groups, respectively. Similarly, their phosphorylation levels were also significantly decreased in the ATM-siRNA group (t=14.35, P<0.01 and t=8.46, P<0.01, respectively and a significant decrease in phosphorylated Chk2 was observed in the Chk2-siRNA group (t=7.28, P<0.01 when compared with the CpG+X-ray group.

    CALIOPE, the CP Abberant Leptons in o-Ps Experiment, searches for CP-violating gamma ray angular correlations in the decay of positronium. It uses a cylindrical array of sodium iodide detectors and an electromagnet to spin-polarize the positronium. Systematics related to the magnetic field, uncertainty of decay origin, and detector geometry and inefficiencies are studied using two Monte Carlo simulations of varying complexity. We present the results of systematics studied using these Monte Carlo simulations and their ultimate impact on the experiment's sensitivity.

  15. Measurement of the CP violating phase βs in B0s J/ΨΦ decays

    The CP violating phase β j/ΨΦs is measured in decays of B0s → J/ΨΦ. This measurement uses 5.2 fb-1 of data collected in √s = 1.96 TeV p$\\bar{p}$ collisions at the Fermilab Tevatron with the CDF Run-II detector. CP violation in the Bs0-$\\bar{B}$s0 system is predicted to be very small in the Standard Model. However, several theories beyond the Standard Model allow enhancements to this quantity by heavier, New Physics particles entering second order weak mixing box diagrams. Previous measurements have hinted at a deviation from the Standard Model expectation value for βsJ/ΨΦ with a significance of approximately 2σ. The measurement described in this thesis uses the highest statistics sample available to date in the Bs0 → J/ΨΦ decay channel, where J/Ψ → μ+μ- and Φ → K+K-. Furthermore, it contains several improvements over previous analyses, such as enhanced signal selection, fully calibrated particle ID and flavour tagging, and the inclusion of an additional decay component in the likelihood function. The added decay component considers S-wave states of KK pairs in the Bs0 → J/Ψ K+K- channel. The results are presented as 2-dimensional frequentist confidence regions for βsJ/ΨΦ and ΔΓ (the width difference between the Bs0 mass eigenstates), and as a confidence interval for βsJ/ΨΦ of [0.02,0.52] U [1.08, 1.55] at the 68% confidence level. The measurement of the CP violating phase obtained in this thesis is complemented by the world's most precise measurement of the lifetime τs = 1.53 ± 0.025 (stat.) ± 0.012 (syst.) ps and decay width difference ΔΓ = 0.075 ± 0.035 (stat.) ± 0.01 (syst.) ps-1 of the B

    The intrinsic acid-base properties of the hexa-2'-deoxynucleoside pentaphosphate, d(ApGpGpCpCpT) [=(A1∙G2∙G3∙C4∙C5∙T6)=(HNPP)⁵⁻] have been determined by ¹H NMR shift experiments. The pKa values of the individual sites of the adenosine (A), guanosine (G), cytidine (C), and thymidine (T) residues were measured in water under single-strand conditions (i.e., 10% D₂O, 47 °C, I=0.1 M, NaClO₄). These results quantify the release of H⁺ from the two (N7)H⁺ (G∙G), the two (N3)H⁺ (C∙C), and the (N1)H⁺ (A) units, as well as from the two (N1)H (G∙G) and the (N3)H (T) sites. Based on measurements with 2'-deoxynucleosides at 25 °C and 47 °C, they were transferred to pKa values valid in water at 25 °C and I=0.1 M. Intramolecular stacks between the nucleobases A1 and G2 as well as most likely also between G2 and G3 are formed. For HNPP three pKa clusters occur, that is those encompassing the pKa values of 2.44, 2.97, and 3.71 of G2(N7)H⁺, G3(N7)H⁺, and A1(N1)H⁺, respectively, with overlapping buffer regions. The tautomer populations were estimated, giving for the release of a single proton from five-fold protonated H₅(HNPP)(±) , the tautomers (G2)N7, (G3)N7, and (A1)N1 with formation degrees of about 74, 22, and 4%, respectively. Tautomer distributions reveal pathways for proton-donating as well as for proton-accepting reactions both being expected to be fast and to occur practically at no "cost". The eight pKa values for H₅(HNPP)(±) are compared with data for nucleosides and nucleotides, revealing that the nucleoside residues are in part affected very differently by their neighbors. In addition, the intrinsic acidity constants for the RNA derivative r(A1∙G2∙G3∙C4∙C5∙U6), where U=uridine, were calculated. Finally, the effect of metal ions on the pKa values of nucleobase sites is briefly discussed because in this way deprotonation reactions can easily be shifted to the physiological pH range.

    Full Text Available BACKGROUND: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS is one of the risk factors of impaired male fertility potential. Studies have investigated the effect of CP/CPPS on several semen parameters but have shown inconsistent results. Hence, we performed a systematic literature review and meta-analysis to assess the association between CP/CPPS and basic semen parameters in adult men. METHODS: Systematic literature searches were conducted with PubMed, EMBASE and the Cochrane Library up to August 2013 for case-control studies that involved the impact of CP/CPSS on semen parameters. Meta-analysis was performed with Review Manager and Stata software. Standard mean differences (SMD of semen parameters were identified with 95% confidence intervals (95% CI in a random effects model. RESULTS: Twelve studies were identified, including 999 cases of CP/CPPS and 455 controls. Our results illustrated that the sperm concentration and the percentage of progressively motile sperm and morphologically normal sperm from patients with CP/CPPS were significantly lower than controls (SMD (95% CI -14.12 (-21.69, -6.63, -5.94 (-8.63, -3.25 and -8.26 (-11.83, -4.66, respectively. However, semen volume in the CP/CPPS group was higher than in the control group (SMD (95% CI 0.50 (0.11, 0.89. There was no significant effect of CP/CPPS on the total sperm count, sperm total motility, and sperm vitality. CONCLUSIONS: The present study illustrates that there was a significant negative effect of CP/CPPS on sperm concentration, sperm progressive motility, and normal sperm morphology. Further studies with larger sample sizes are needed to better illuminate the negative impact of CP/CPPS on semen parameters.

    CP violating phase φs appears in b → anti(c)cs transitions due to the interference between the direct decay and the decay after the Bs⁰-anti(Bs⁰) mixing. In SM, φs = -2βs + δP, where -2βs is related to CKM matrix elements and δP is the penguin phase where contributions due to penguin diagrams are taken into account, being this δP phase also the main source of theoretical uncertainty in φs. This φs phase is very sensitive to possible NP (new particles contributing to box diagrams during the mixing, several possible BSM scenarios are presented), so δP should be estimated in order to disentangle these penguin pollution contributions from possible NP contributions, φs(LHCb) = -2βs + δP + δNP. The decay Bs⁰ → J/ψ K⁺K⁻ is a golden decay for φs measurement: latest LHCb combined result also including Bs⁰ → J/ψ π⁺π⁻ measurements is φs = -0.010 ± 0.039 rad, which is in excellent agreement with SM. The penguin pollution phase δP can be estimated using B⁰ → J/ψ ρ⁰ and B...

  3. Phase aberration effects in elastography.

    In sonography, phase aberration plays a role in the corruption of sonograms. Phase aberration does not have a significant impact on elastography, if statistically similar phase errors are present in both the pre- and postcompression signals. However, if the phase errors are present in only one of the pre- or postcompression signal pairs, the precision of the strain estimation process will be reduced. In some cases, increased phase errors may occur only in the postcompression signal due to changes in the tissue structure with the applied compression. Phase-aberration effects increase with applied strain and may be viewed as an image quality derating factor, much like frequency-dependent attenuation or undesired lateral tissue motion. In this paper, we present a theoretical and simulation study of the effects of phase aberration on the elastographic strain-estimation process, using the strain filter approach.

    We present a measurement of the time-dependent $CP$-violating asymmetry in $B^{0}_s\\to J/\\psi\\phi$ decays, using data collected with the LHCb detector at the LHC. The decay time distribution of $B^{0}_s\\to J/\\psi\\phi$ is characterized by the decay widths $\\Gamma_{\\mathrm{H}}$ and $\\Gamma_{\\mathrm{L}}$ of the heavy and light mass eigenstates of the $B^{0}_s-\\overline{B}^{0}_s$ system and by a $CP$-violating phase $\\phi_s$. In a sample of about 8500 $B^{0}_s\\to J/\\psi\\phi$ events isolated from $0.37$~fb$^-1$ of $pp$ collisions at $\\sqrt{s}=7$ TeV we measure $\\phi_s \\: = \\: 0.15 \\: \\pm \\: 0.18 \\; \\mathrm{(stat)} \\: \\pm \\: 0.06 \\; \\mathrm{(syst)}$ rad.

    We present a measurement of the \\CP-violating parameter \\betas using approximately 6500 $\\BsJpsiPhi$ decays reconstructed with the CDF\\,II detector in a sample of $p\\bar p$ collisions at $\\sqrt{s}=1.96$ TeV corresponding to 5.2 fb$^{-1}$ integrated luminosity produced by the Tevatron Collider at Fermilab. We find the \\CP-violating phase to be within the range $\\betas \\in [0.02, 0.52] \\cup [1.08, 1.55]$ at 68% confidence level where the coverage property of the quoted interval is guaranteed using a frequentist statistical analysis. This result is in agreement with the standard model expectation at the level of about one Gaussian standard deviation. We consider the inclusion of a potential $S$-wave contribution to the $\\Bs\\to J/\\psi K^+K^-$ final state which is found to be negligible over the mass interval $1.009 < m(K^+K^-)<1.028 \\gevcc$. Assuming the standard model prediction for the \\CP-violating phase \\betas, we find the \\Bs decay width difference to be $\\deltaG = 0.075 \\pm 0.035\\,\\textrm{(stat)} \\pm 0.006\\,\\textrm{(syst)} \\ps$. We also present the most precise measurements of the \\Bs mean lifetime $\\tau(\\Bs) = 1.529 \\pm 0.025\\,\\textrm{(stat)} \\pm 0.012\\,\\textrm{(syst)}$ ps, the polarization fractions $|A_0(0)|^2 = 0.524 \\pm 0.013\\,\\textrm{(stat)} \\pm 0.015\\,\\textrm{(syst)}$ and $|A_{\\parallel}(0)|^2 = 0.231 \\pm 0.014\\,\\textrm{(stat)} \\pm 0.015\\,\\textrm{(syst)}$, as well as the strong phase $\\delta_{\\perp}= 2.95 \\pm 0.64\\,\\textrm{(stat)} \\pm 0.07\\,\\textrm{(syst)} \\textrm{rad}$. In addition, we report an alternative Bayesian analysis that gives results consistent with the frequentist approach.

    We obtain analytic expressions for the energy and polar-angle double differential distributions of a secondary lepton +(-) arising from the decay of ($\\overline{t}$) in + - → $t\\overline{t}$ with an anomalous decay vertex. We also obtain analytic expressions for the various differential cross-sections with the lepton energy integrat ed over. In this case, we find that the angular distributions of the secondary lepton do not depend on the anomalous coupling in the decay, regardless of possible anomalous couplings occurring in the production amplitude for + - → $t\\overline{t}$. Our study includes the effect of longitudinal - and + beam polarization. We also study the lepton energy and beam polarization dependence of certain CP-violating lepton angular asymmetries arising from an anomalous decay vertex and compare them with the asymmetries arising due to CP-violation in the production process due to the top electric or weak dipole moment.

    A time-dependent angular analysis of $B_s^0\\to\\psi(2S)\\phi$ decays is performed using data recorded by the LHCb experiment. The data set corresponds to an integrated luminosity of 3.0\\invfb collected during Run 1 of the LHC. The CP-violating phase and decay-width difference of the $B_s^0$ system are measured to be $\\phi_s = 0.23^{+0.29}_{-0.28} \\pm 0.02$ rad and $\\Delta\\Gamma_s = 0.066^{+0.041}_{-0.044} \\pm 0.007$ ps$^{-1}$, respectively, where the first uncertainty is statistical and the second systematic. This is the first time that $\\phi_s$ and $\\Delta\\Gamma_s$ have been measured in a decay containing the $\\psi(2S)$ resonance.

    2015-01-01

    We discuss the impact of non-standard neutrino matter interactions (NSI) in propagation on the determination of CP phase in the context of the long baseline accelerator experiments such as Deep Underground Neutrino Experiment (DUNE). DUNE will mainly address the issue of CP violation in the leptonic sector. Here we study the role of NSI and its impact on the question of observing the CP violation signal at DUNE. We consider two scenarios of oscillation with three active neutrinos in absence and presence of NSI. We elucidate the importance of ruling out subdominant new physics effects introduced by NSI in inferring CP violation signal at DUNE by considering NSI terms collectively as well as by exploiting the non-trivial interplay of moduli and phases of the NSI terms. We demonstrate the existence of NSI-SI degeneracies which need to be eliminated in reliable manner in order to make conclusive statements about the CP phase.

  10. Model-Independent Analysis of CP Violation in Charmed Meson Decays

    2015-01-01

    We present a model-independent analysis of CP violation, inspired by recent experimental observations, in charmed meson decays. The topological diagram approach is used to study direct CP asymmetries for singly Cabibbo-suppressed two-body hadronic decays of charmed mesons. We extract the magnitudes and relative phases of the corresponding topological amplitudes from available experimental information. In order to get more precise and reliable estimates of direct CP asymmetries, we take into account contributions from all possible strong penguin amplitudes, including the internal $b$-quark penguin contributions. We also study flavor SU(3) symmetry breaking effects in these decay modes and consequently, predict direct CP asymmetries of unmeasured modes.

    A CpG-containing DNA oligonucleotide functionalized with the 2-(N-formyl-N-methyl)aminoethyl thiophosphate protecting group (CpG ODN fma1555) was prepared from phosphoramidites 1a-d using solid-phase techniques. The oligonucleotide behaved as a prodrug by virtue of its conversion to the well-studied immunomodulatory CpG ODN 1555 through thermolytic cleavage of the 2-(N-formyl-N-methyl)aminoethyl thiophosphate protecting group. Such a conversion occurred at 37 degrees C with a half-time of 73 h. The immunostimulatory properties of CpG ODN fma1555 were evaluated in two in vivo assays, one of which consisted of mice challenged in the ear with live Leishmania major metacyclic promastigotes. Local intradermal administration of CpG ODN fma1555 was as effective as that of CpG ODN 1555 in reducing the size of Leishmania lesions over time. In a different infectious model, CpG ODN 1555 prevented the death of Tacaribe-infected mice (43% survival) when administered between day 0 and 3 post infection. Administration of CpG ODN fma1555 three days before infection resulted in improved immunoprotection (60-70% survival). Moreover, co-administration of CpG ODN fma1555 and CpG ODN 1555 in this model increased the window for therapeutic treatment against Tacaribe virus infection, and thus supports the use of thermolytic oligonucleotides as prodrugs in the effective treatment of infectious diseases.

    The aim of the study was to investigate the effect of living probiotics, probiotic DNA and the synthetic oligodeoxynucleotides containing CpG motifs (CpG-ODN) on both immune response and intestinal barrier function in ovalbumin-sensitized rat and the underlying mechanisms. Brown-Norway rats were orally sensitized with ovalbumin, and living probiotics, probiotic DNA extraction, synthetic CpG-ODN or non-CpG ODN control was administered. In the living probiotics, probiotic DNA and CpG-ODN groups, the allergic response was significantly inhibited, the Th1/Th2 cytokine balance was shifted away from Th2 side, the percentage of CD4(+) CD25(+high) Treg cells was increased, and the intestinal barrier function was improved. The levels of toll-like receptor (TLR) 9 mRNA and nuclear factor (NF)-κB activity, as well as the IκB-α phosphorylation (p-IκB-α) was significantly increased in these three intervention groups compared with the OVA-positive group, whereas no such effects were found in the non-CpG ODN control group. These data show that the probiotic genomic DNA and the synthetic CpG-ODN was comparable with living probiotics in preventing food allergic response by immune modulation and intestinal barrier function enhancement, and the activation of TLR9/NF-κB signal pathway might be involved in this process.

    In spite of the addictive properties of cannabinoids, under certain circumstances, they can evoke strong anxiogenic and aversive responses in humans and in animal tests of anxiety. Effects of different doses of CP 55,940 (10, 20, and 40 microg/kg) were tested in the low-light, familiar (LF) apparatus test condition of the social interaction test. The 40-microg/kg dose of CP 55,940 significantly decreased the time spent in social interaction, indicating an anxiogenic effect. This dose also had an independent effect of reducing locomotor activity. In rats tested undrugged 24 h after testing with 40 microg/kg, there was a significant anxiogenic effect, indicating conditioned anxiety. The group of rats injected with 40 microg/kg immediately after the social interaction test showed an unexpected significant anxiolytic effect when tested undrugged 24 h later. In an additional experiment, rats were tested in the high-light, familiar (HF) apparatus test condition after 10 or 40 microg/kg, and only those that were tested after 40 microg/kg showed an anxiogenic effect on the test day and a conditioned anxiogenic effect when tested undrugged 24 h later. Once again, those injected with 40 microg/kg after the social interaction test displayed an anxiolytic effect when tested undrugged 24 h later. We provide the first evidence for unconditioned and conditioned anxiogenic-like responses to a cannabinoid agonist in the social interaction test.

    采用电火花内冲液加工方式,分别研究了开路电压、伺服参考电压、电容及电流等电参数对45%SiCp/Al与Al2024合金深小孔加工效率、电极损耗及加工孔径的影响。结果表明:当电源放电能量越大、放电频率越高时,加工效率越高,且电极损耗越大;而在相同加工条件下,SiCp/Al的加工效率和电极损耗都明显高于Al2024合金,且开路电压和电容对SiCp/Al孔径的影响较大。%By the way of inner jetted electro-discharge machining ,the effect of the electrical parameters (open-circuit voltage,servo reference voltage,capacitance and current) on material removal rate,tool wear rate and diameter of machining processing deep micro-holes of 45 % SiCp/Al and Al2024 alloy were investigated. It turns out that when the power produces larger discharge energy and higher discharge frequency,the material removal rate and tool wear rate is more. But under the same machining conditions,the material removal rate and tool wear rate of machining SiCp/Al is more than machining Al2024 alloy,in which the open-circuit voltage and capacitance impact the diameter of machining holes greatly.

    We argue that in the minimal SUSY extension of the standard model, CP-violation cannot be explained through SUSY phases alone. But SYSY graphs, especially with gluinos, can make important contributions to CP-violation through the Kobayashi-Maskawa phase.

    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

  17. CP Violation in Supersymmetric U(1)' Models

    The supersymmetric CP problem is studied within superstring-motivated extensions of the MSSM with an additional U(1)' gauge symmetry broken at the TeV scale. This class of models offers an attractive solution to the mu problem of the MSSM, in which U(1)' gauge invariance forbids the bare mu term, but an effective mu parameter is generated by the vacuum expectation value of a Standard Model singlet S which has superpotential coupling of the form SH_uH_d to the electroweak Higgs doublets. The effective mu parameter is thus dynamically determined as a function of the soft supersymmetry breaking parameters, and can be complex if the soft parameters have nontrivial CP-violating phases. We examine the phenomenological constraints on the reparameterization invariant phase combinations within this framework, and find that the supersymmetric CP problem can be greatly alleviated in models in which the phase of the SU(2) gaugino mass parameter is aligned with the soft trilinear scalar mass parameter associated with the ...

  18. Beautiful CP violation

    1997-09-24

    CP violation is observed to date only in K{sup 0} decays and is parameterizable by a single quantity {epsilon}. Because it is one of the least understood phenomena in the Standard Model and holds a clue to baryogenesis, it must be investigated further. Highly specialized searches in K{sup 0} decays are possible. Effects in B decays are much larger. In addition to the traditional B{sub d} {yields} J/{psi}K{sub S}, {pi}{sup +}{pi}{sup {minus}} asymmetries, CP violation could be searched for in already existing inclusive B data samples. The rapid B{sub s}--{anti B}{sub s} oscillations cancel in untagged B{sub s} data samples, which therefore allow feasibility studies for the observation of CP violation and the extraction of CKM elements with present vertex detectors. The favored method for the extraction of the CKM angle {gamma} is shown to be unfeasible and a solution is presented involving striking direct CP violation in charged B decays. Novel methods for determining the B{sub s} mixing parameter {Delta}m are described without the traditional requirement of flavor-specific final states.

  20. On effects of gauging on symplectic structure, the Hopf term coupled to $CP^{1}$ model, and fractional spin

    Chakraborty, B

    1999-01-01

    We couple the Hopf term to the relativistic $CP^1$ model and carry out the Hamiltonian analysis at the classical level. The symplectic structure of the model given by the set of Dirac Brackets among the phase space variables is found to be the same as that of the pure $CP^1$ model. This symplectic structure is shown to be inherited from the global SU(2) invariant $S^3$ model, and undergoes no modification upon gauging the U(1) subgroup, except the appearance of an additional first class constraint generating U(1) gauge transformation. We then address the question of fractional spin as imparted by the Hopf term at the classical level. For that we construct the expression of angular momentum through both symmetric energy-momentum tensor as well as through Noether's prescription. Both the expressions agree for the model indicating no fractional spin is imparted by this term at the classical level-a result which is at variance with what has been claimed in the literature. We provide an argument to explain the dis...

    berrant immune responses have been identified in obesity; however, immune cells of lymph nodes residing in the inflammatory environment of visceral adipose tissue have been largely overlooked. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) can reduce inflammation and modify T-cell function and therefore may improve immune function in obesity. Thus, we determined the effects of feeding fish oil (FO) containing EPA and DHA on mesenteric lymph node (MLN) immune cell function. In this study, 14-week-old obese, leptin receptor-deficient JCR:LA-cp rats (cp/cp) (n=10 per group) were randomized to one of three nutritionally adequate diets for 3 weeks: control (ctl, 0% EPA+DHA), low FO (LFO, 0.8% w/w EPA+DHA) or high FO (HFO, 1.4% w/w EPA+DHA). Lean JCR:LA-cp (Cp/cp or Cp/Cp) rats (n=5) were fed ctl diet. MLN cell phospholipid (PL) fatty acid composition, phenotypes and cytokine production were measured. Obese ctl rats produced more IL-1beta, IL-4 and IL-10, despite a higher proportion of (n-3) polyunsaturated fatty acids (PUFAs) and a lower (n-6):(n-3) PUFA ratio in MLN PL compared with lean ctl rats (PJCR:LA-cp rats have impaired responses of MLN immune cells to mitogen stimulation and altered PL fatty acid composition. Feeding FO lowered the ex vivo inflammatory response (HFO only) and production of Th2 cytokines, without changing IL-2 production from ConA-stimulated splenocytes, which may occur independent of leptin signalling.

    Full Text Available High prevalence of erectile dysfunction (ED has been observed in patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS. However, whether or not CP/CPPS is a risk factor of ED remains unknown and controversial. Therefore, we conducted this systematic review and meta-analysis to evaluate the relationship between CP/CPPS and ED.PubMed, Embase, Web of Science, and The Cochrane Library were searched up to November 11, 2014 to identify studies reporting the association between CP/CPPS and ED. Case-control, cohort and cross-sectional studies were included. Quality of the included studies was assessed. The odds ratio of ED and the mean difference of five-item International Index of Erectile Function (IIEF-5 score were pooled using a random effects model. Subgroup analysis and sensitivity analyses were performed.Three cross-sectional studies, two case-control studies, and four retrospective studies with 31,956 participants were included to calculate the pooled odds ratio of ED, and two studies with 1499 participants were included to calculate the pooled mean difference of IIEF-5 scores. A strong correlation was found between CP/CPPS and ED (pooled odds ratio: 3.02, 95% CI: 2.18-4.17, P < 0.01, with heterogeneity across studies (I2 = 65%; P < 0.01. A significant decrease in the IIFE-5 score was observed in the CP/CPPS group (pooled mean difference: -4.54, 95% CI: -5.11--3.98; P < 0.01.Our study indicates that patients with CP/CPPS have an increased risk of suffering from ED. Assessment of erectile function is necessary for the therapy of patients with CP/CPPS. Further evidence is necessary to confirm the relationship between CP/CPPS and ED.

    2008-01-01

    The influence of porosity on the wear behavior of high volume fraction (61%) SiCp/Cu composite produced by pressureless infiltration was studied using a sliding, reciprocating and vibrating(SRV) machine. SiCp/Cu composites slid against hardened GCr15 bearing steel ball in the load range of 40-200 N. The results show that the wear rate increases with increasing porosity. The composite containing low porosity shows excellent wear resistance, which is attributed to the presence of mechanically mixed layer on the worn surface. In this case, the dominant wear mechanism is oxidative wear. Comparatively, the composite containing high porosity exhibits inferior wear resistance. Fracture and spalling of the particles are considered as the main causes of severe wear. Third body abrasion is the controlling wear mechanism. In addition, porosity has more important influence on wear rate at high load than at low load. This is associated with the fact that the fracture and spalling of particles is a process of crack initiation and propagation. At lower load, the pores beneath the worn surface can not propagate significantly, while the pores become unstable and easily propagate under high load, which results in a higher wear rate.

    We study the CP-violation effects from two types of neutrino mass matrices with (i) (M{sub ν}){sub ee}=0, and (ii) (M{sub ν}){sub ee}=(M{sub ν}){sub eμ}=0, which can be realized by the high-dimensional lepton number violating operators ℓ{sup -bar}{sub R}{sup c}γ{sup μ}L{sub L}(D{sub μ}Φ)Φ{sup 2} and ℓ{sup -bar}{sub R}{sup c}l{sub R}(D{sub μ}Φ){sup 2}Φ{sup 2}, respectively. In (i), the neutrino mass spectrum is in the normal ordering with the lightest neutrino mass within the range 0.002 eV≲m{sub 0}≲0.007 eV. Furthermore, for a given value of m{sub 0}, there are two solutions for the two Majorana phases α{sub 21} and α{sub 31}, whereas the Dirac phase δ is arbitrary. For (ii), the parameters of m{sub 0}, δ, α{sub 21}, and α{sub 31} can be completely determined. We calculate the CP-violating asymmetries in neutrino–antineutrino oscillations for both mass textures of (i) and (ii), which are closely related to the CP-violating Majorana phases.

    2013-08-30

    We observe a generic connection between LHC Higgs data and electroweak baryogenesis: the particle that contributes to the CP-odd hgg or hγγ vertex would provide the CP-violating source during a first-order phase transition. It is illustrated in the two Higgs doublet model that a common complex phase controls the lightest Higgs properties at the LHC, electric dipole moments, and the CP-violating source for electroweak baryogenesis. We perform a general parametrization of Higgs effective couplings and a global fit to the LHC Higgs data. Current LHC measurements prefer a nonzero phase for tanβ≲1 and electric dipole moment constraints still allow an order-one phase for tanβ∼1, which gives sufficient room to generate the correct cosmic baryon asymmetry. We also give some prospects in the direct measurements of CP violation in the Higgs sector at the LHC.

    We present a study of the decay $B^- \\to D^0_{(CP)}K^-$ and its charge conjugate, where $D^0_{(CP)}$ is reconstructed in both a non-CP flavor eigenstate and in CP (CP-even and CP-odd) eigenstates, based on a sample of 382 million $\\Upsilon{(4S)} \\to B \\bar{B}$ decays collected with the BABAR detector at the PEP-II $e^+e^-$ storage ring. We measure the direct CP asymmetries $A_{CP\\pm}$ and the ratios of the branching fractions $R_{CP\\pm}$: $A_{CP+} = 0.27\\pm 0.09\\mathrm{(stat)}\\pm 0.04\\mathrm{(syst)}$, $A_{CP-} =-0.09\\pm 0.09\\mathrm{(stat)}\\pm 0.02\\mathrm{(syst)}$, $R_{CP+} = 1.06\\pm 0.10\\mathrm{(stat)}\\pm 0.05\\mathrm{(syst)}$, $R_{CP-} = 1.03\\pm 0.10\\mathrm{(stat)}\\pm 0.05\\mathrm{(syst)}$. These results will help to better constrain the gamma phase parameter of the Cabibbo-Kobayashi-Maskawa quark mixing matrix.

    Measurement of the mixing-induced CP-violating phase Greek-Small-Letter-Phi {sub s} in B{sub 0}{sup s} decays is of prime importance in probing new physics. Here 7421 {+-} 105 signal events from the dominantly CP-odd final state J/ Greek-Small-Letter-Psi Greek-Small-Letter-Pi {sup +} Greek-Small-Letter-Pi {sup -} are selected in 1 fb{sup -}1 of pp collision data collected at {radical}s = 7 TeV with the LHCb detector. A timedependent fit to the data yields a value of Greek-Small-Letter-Phi {sub s} = -0.019{sup +0.173+0.004}{sub -0.174-0.003} rad, consistent with the Standard Model expectation. No evidence of direct CP violation is found.

    Transgenic cotton (Cossypium hirsutum L.) varieties, adapted to China, have been bred that express two genes for resistance to insects, the CrylAc gene from Bacillus thuringiensis (Berliner) (Bt), and a trypsin inhibitor gene from cowpea (CpTI). Effectiveness of the double gene modification in conferring resistance to cotton bollworm, Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae), was studied in laboratory and field experiments. In each experiment, performance of Bt+CpTI cotton was compared with Bt cotton and to a conventional nontransgenic variety. Larval survival was lower on both types of transgenic variety, compared with the conventional cotton. Survival of first-, second-, and third-stage larvae was lower on Bt+CpTI cotton than on Bt cotton. Plant structures differed in level of resistance, and these differences were similar on Bt and Bt + CpTI cotton. Likewise, seasonal trends in level of resistance in different plant structures were similar in Bt and Bt+CpTI cotton. Both types of transgenic cotton interfered with development of sixth-stage larvae to adults, and no offspring was produced by H. armigera that fed on Bt or Bt+CpTI cotton from the sixth stage onward. First-, second-, and third-stage larvae spent significantly less time feeding on transgenic cotton than on conventional cotton, and the reduction in feeding time was significantly greater on Bt+CpTI cotton than on Bt cotton. Food conversion efficiency was lower on transgenic varieties than on conventional cotton, but there was no significant difference between Bt and Bt+CpTI cotton. In 3-yr field experimentation, bollworm densities were greatly suppressed on transgenic as compared with conventional cotton, but no significant differences between Bt and Bt+CpTI cotton were found. Overall, the results from laboratory work indicate that introduction of the CpTI gene in Bt cotton raises some components of resistance in cotton against H. armigera, but enhanced control of H. armigera under field

    In present days MMC's are widely used in most of the industries, like automobiles, aerospace, minerals and marine industries, because of its high specific strength to weight ratio. There are many types of reinforcements are available, selection of reinforcement is depends on availability, cost and desired reinforcement properties. In our study Al-1100 is selected as a primary material and Titanium carbide particle (TiCp) of 44 pm size as reinforcement and synthesized by manual stir casting method, by varying the reinforcement percentage. K2DF6 salt was used as wetting agent in order to improve the wetting behaviour of the reinforcement and same was observed in optical micrographs. Further, prepared composite materials are subjected to machinability studies by using lathe tool dynamometer in order to evaluate the cutting force, surface roughness with respect to reinforcement percentage and tool material. From the results, it is observed that the hardness and surface roughness of a specimen increases with the increasing of reinforcement percentage and Hardness of the tool material respectively.

    Piperidine-based peroxisome proliferator-activated receptor-α agonists are agents that are efficacious in improving lipid, glycemic, and inflammatory indicators in diabetes and obesity. This study sought to determine whether CP-900691 ((S)-3-[3-(1-carboxy-1-methyl-ethoxy)-phenyl]-piperidine-1-carboxylic acid 4-trifluoromethyl-benzyl ester; CP), a member of this novel class of agents, by decreasing plasma triglycerides, could prevent diabetic nephropathy in the Black and Tan, BRachyuric (BTBR) ob/ob mouse model of type 2 diabetes mellitus. Four-week old female BTBR WT and BTBR ob/ob mice received either regular chow or one containing CP (3 mg/kg per day) for 14 weeks. CP elevated plasma high-density lipoprotein, albuminuria, and urinary excretion of 8-epi PGF(2α), a product of the nonenzymatic metabolism of arachidonic acid and whose production is elevated in oxidative stress, in BTBR WT mice. In BTBR ob/ob mice, CP reduced plasma triglycerides and non-esterified fatty acids, fasting blood glucose, body weight, and plasma interleukin-6, while concomitantly improving insulin resistance. Despite these beneficial metabolic effects, CP had no effect on elevated plasma insulin, 8-epi PGF(2α) excretion, and albuminuria, and surprisingly, did not ameliorate the development of diabetic nephropathy, having no effect on the accumulation of renal macrophages, glomerular hypertrophy, and increased mesangial matrix expansion. In addition, CP did not increase plasma high-density lipoprotein in BTBR ob/ob mice, while paradoxically increasing total cholesterol levels. These findings indicate that 8-epi PGF(2α), possibly along with hyperinsulinemia and inflammatory and dysfunctional lipoproteins, is integral to the development of diabetic nephropathy and should be considered as a potential target of therapy in the treatment of diabetic nephropathy.

    For the electronic packaging applications, copper matrix composites reinforced with different sized SiC particles (10 μm, 20 μm and 63 μm) were fabricated by squeeze casting technology. And the effect of particle size on their thermo-physical properties was discussed. The composites are free of porosity and the SiC particles are distributed uniformly in the composites. It is found that the mean linear thermal expansion coefficients(20 - 100 ℃ ) of SiCp/Cu composites are in the range of (8.4 - 9.2) × 10-6/℃, and smaller expansion coefficient can be obtained for the composites with finer SiC particles because of the larger restriction in expansion through interfaces. Their thermal conductivities are reduced with the decrease of SiC sizes. This is attributed to the fact that the negative effect of interfacial thermal resistance becomes increasingly dominant as the particles becomes smaller.

    The CP-violating effects to the subprocess gg → H+ H- are studied in the mSUGRA scenario at the CERN large hadron collider, by taking into account the experimental bounds of electron and neutron electric dipole moments.The CP-violating effects in this process are related to the complex phases ofμ and Af in the mSUGRA scenario. In our calculation we consider smallCP phases ofμ and Af and neglect the effects of neutral Higgs boson mixing. In this case the CP effects to the process mainly come from the complex couplings of Higgs-squark-squark. We find a strong dependence of charged Higgs boson pair production rate on the complex couplings in the parameter space of minimal supersymmetric standard model``

    While the Kobayashi-Maskawa single phase origin of CP violation passed its first crucial precision test in $B→ J/ K_{S}$, the chirality of weak $b$-quark couplings has not yet been carefully tested. We discuss recent proposals for studying the chiral and CP-violating structures of these couplings in radiative and hadronic $B$ decays.

    Current experimental data on the 125~GeV Higgs boson still allow room for large CP violation.~The observables usually considered in this context are triple product asymmetries, which require an input of four visible particles after imposing momentum conservation.~We point out a new class of CP-violating effects in Higgs physics without recourse to triple products.~They may arise if the process involves an interference of different intermediate particles, which provide distinct "strong phases" in the form of the Breit-Wigner widths in addition to possible "weak phases" that arise from CP violating couplings of the Higgs in the Lagrangian.~As an example, we propose a forward-backward asymmetry of the charged lepton in the three-body Higgs decay, $h\\to \\ell^-\\ell^+ \\gamma$, as a probe for CP-violating Higgs couplings to $Z\\gamma$ and $\\gamma\\gamma$ pairs.~Other processes exhibiting this type of CP-violation are also discussed.

    2024Al based composites reinforced by a hybrid of SiC whisker and SiC nanoparticle were fabricated by a squeeze casting route. In the (SiCw+SiCp)/Al composites, the volume fraction of SiC whisker is 20% and that of SiC nanoparticle is 2%, 5% and 7%,respectively. The as cast composites were solution treated followed by aging treatment. The experimental results show that the SiC nanoparticles are more effective in improving the hardness and tensile strength of the composites than SiC whiskers. The hardening kinetics of the composites is enhanced by reinforcements addition and the peak aging time is 4-5 h. The hardness of all the hybrid composite decreases at the initial aging stage, suggesting that dislocation recovery softening process coexists with precipitation hardening. DSC study shows that the GP zone formation of the hybrid composites is suppressed.

    Full Text Available Abstract Background Developing a model for codon substitutions is essential for the analyses of protein sequences. Recent studies on the mutation rates in the non-coding regions have shown that CpG mutation rates in the human genome are negatively correlated to the local GC content and to the densities of functional elements. This study aimed at understanding the effect of genomic features, namely, GC content, gene density, and frequency of CpG islands, on the rates of codon substitution in human chromosomes. Results Codon substitution rates of CpG to TpG mutations, TpG to CpG mutations, and non-CpG transitions and transversions in humans were estimated by comparing the coding regions of thousands of human and chimpanzee genes and inferring their ancestral sequences by using macaque genes as the outgroup. Since the genomic features are depending on each other, partial regression coefficients of these features were obtained. Conclusion The substitution rates of codons depend on gene densities of the chromosomes. Transcription-associated mutation is one such pressure. On the basis of these results, a model of codon substitutions that incorporates the effect of genomic features on codon substitution in human chromosomes was developed.

    Orthoses are commonly prescribed to children with cerebral palsy (CP) in order to provide foot correction and to improve ambulatory function. Immediate effects of ankle foot orthosis (AFOs) have been investigated, but long term kinematic effects are lacking clinical evidence. To determine changes in pediatric patients with Cerebral Palsy's 3D ankle and foot segment motion between initial, and follow up visits (18 month average time differences) in both barefoot gait and gait with their ankle foot orthotic (AFO). We will also investigate intra visit changes between barefoot and AFO gait. A prospective cohort study. Children's Hospital of Wisconsin, Department of Orthopaedic Surgery. Medical College of Wisconsin. A total of 23 children with CP, mean age 10.5 years (6.2 to 18.1) were clinically prescribed either a solid ankle foot orthotic (SAFO), hinged ankle foot orthotic (HAFO), or supramalleolar orthotic (SMO). Holes were cut in the study orthoses so that electromagnetic markers could be directly placed on the skin. A 6 foot segment model (6SF) was used. Kinematic and kinetic data was recorded for each patient's initial and follow up visit (18 month follow up average, 15 to 20 months range) RESULTS: For the SAFO group (gait with AFO), a significant decrease in dorsiflexion was found between the initial and third visit (p=.008). Furthermore, the SAFO group (barefoot gait), had an increased eversion at the midfoot for most of the gait cycle (p < .008). Sagittal forefoot ROM is reduced for all three groups between the barefoot and AFO groups. Use of AFOs long term either maintained or improved foot deformities or dysfunction.

    The effects of the sodium-hydrogen (Na/H) exchange inhibitor cariporide (HOE642), on insulin sensitivity and vascular function were studied in the JCR:LA-cp rat and the db/db mouse. In the insulin-resistant rat, cariporide reduced fasting insulin levels (42%, P JCR:LA-cp insulin-resistant rat, which develops advanced cardiovascular disease and ischemic myocardial lesions. It also improved vascular function in a similar mouse model of insulin resistance. These effects were markedly greater than those of ramipril.

    Important problems in environmental protection and resource management require quantification of parameters at field (large) scale. A numerical model is utilized to construct large-scale capillary pressure (CP) and relative permeability (RP) curves for two-phase flow in heterogeneous porous media. Two-phase flow simulations were performed over a two-dimensional, numerically generated, heterogeneous permeability field. CP and RP curves were constructed for each simulation. The fields ranged in size from 1.25x1.25 m to 5x10 m and had a mean overall log-hydraulic conductivity of [minus]4.6. Flow was vertically downward with the left and right boundaries of the domain remaining impermeable. Following the simulations on heterogeneous fields, homogeneous equivalents were determined and run for sample simulations. The heterogeneous simulations included investigations into the representative elementary volume (REV) for two permeability fields, the effects of fluid properties on CP and RP, and the effects of correlation structure. The equivalent homogeneous simulations explored the feasibility of homogeneous solutions to predict heterogeneous behavior. Results showed that the REVs for fields one and two were a domain size of 50x50 nodes. Fluid property investigations showed that CP decreased when interfacial tension decreased. Structural explorations showed vertical bedding caused an increase in both CP and RP results. A decrease in log-hydraulic conductivity variance caused slight increases in RP and CP. No direct correlation was obtained between homogeneous and heterogeneous flow behavior. A modification could be made to the homogeneous model to allow it to accurately predict heterogeneous flow. 49 refs., 28 figs., 10 tabs.

    2008-01-01

    The effect of Ti-Al on microstructures and mechanical properties of SiCp/Al MMC joints produced by plasma arc in-situ weld-alloying was investigated, in which argon-nitrogen mixture was used as plasma gases and Ti-Al alloy as filling composite. The results show that the formation of needle-like harmful phase Al4C3 is effectively prevented in the weld by in-situ weld-alloying/plasma arc welding with Ti-Al alloy sheet filler whose titanium content is more than 20%. The fluidity of molten pool is improved, and stable molten pool is gained for the addition of the Ti-Al alloy. The mechanical properties of welded joint are effectively enhanced by the compact-grain structure and the new reinforced composites such as Al3Ti, TiN, AlN and TiC welded joint. The test results of mechanical property show that the maximum tensile strength of welded joint gained by adding Ti-60Al alloy is up to 235 MPa. The factors influencing the tensile strength were also investigated.

    We explore the prospects for observing CP violation in the minimal supersymmetric extension of the Standard Model (MSSM) with six CP-violating parameters, three gaugino mass phases and three phases in trilinear soft supersymmetry-breaking parameters, using the CPsuperH code combined with a geometric approach to maximise CP-violating observables subject to the experimental upper bounds on electric dipole moments. We also implement CP-conserving constraints from Higgs physics, flavour physics and the upper limits on the cosmological dark matter density and spin-independent scattering. We study possible values of observables within the constrained MSSM (CMSSM), the non-universal Higgs model (NUHM), the CPX scenario and a variant of the phenomenological MSSM (pMSSM). We find values of the CP-violating asymmetry A{sub CP} in b → sγ decay that may be as large as 3 %, so future measurements of A{sub CP} may provide independent information about CP violation in the MSSM. We find that CP-violating MSSM contributions to the B{sub s} meson mass mixing term ΔM{sub B{sub s}} are in general below the present upper limit, which is dominated by theoretical uncertainties. If these could be reduced, ΔM{sub B{sub s}} could also provide an interesting and complementary constraint on the six CP-violating MSSM phases, enabling them all to be determined experimentally, in principle. We also find that CP violation in the h{sub 2,3}τ{sup +}τ{sup -} and h{sub 2,3} anti tt couplings can be quite large, and so may offer interesting prospects for future pp, e{sup +}e{sup -}, μ{sup +}μ{sup -} and γγ colliders.

    The mixing-induced CP-violating phase ϕ{sub s} in B{sub s}{sup 0} and B{sup ¯}{sub s}{sup 0} decays is measured using the J/ψπ{sup +}π{sup −} final state in data, taken from 3 fb{sup −1} of integrated luminosity, collected with the LHCb detector in 7 and 8 TeV centre-of-mass pp collisions at the LHC. A time-dependent flavour-tagged amplitude analysis, allowing for direct CP violation, yields a value for the phase ϕ{sub s}=70±68±8 mrad. This result is consistent with the Standard Model expectation and previous measurements.

    Supersymmetric models where R-parity is broken via lepton number violation provides an intrinsically supersymmetric explanation for the observed neutrino. The complex phases of the corresponding parameters are constrained by the observed matter anti-matter asymmetry of the universe. Taking bilinear R-parity violation as framework in combination with the assumption of a large lepton asymmetry generated via the Affleck-Dine mechanism at the end of inflation we investigate these constraints in the parameter range compatible with neutrino data.

    Objective:To study the effect of serum HE4 and CP2 contents on the expression of clinical pathological molecules and proliferation molecules in tumor tissue of patients with endometrial carcinoma.Methods:A total of 40 cases of patients who were diagnosed with endometrial carcinoma in our hospital from May 2013 to March 2016 as well as 40 cases of healthy volunteers who received physical examination in our hospital during the same period were selected for study, serum samples were collected to detect HE4, c-myc, ZEB1, CP2, sTn, CA125, CA199 contents, and endometrial carcinoma tissue as well as para-carcinoma tissue were collected to detect P53, E-cad, EpCAM, C-erbB-2, Ki-67 and MACC1 contents.Results:Serum CP2 and HE4 contents of patients with endometrial carcinoma were significantly higher than those of healthy volunteers, and serum CP2 and HE4 contents of endometrial carcinoma patients with FIGO III-IV stage, low differentiation, muscular layer involvement more than 1/2 and cervical involvement were significantly higher than those of endometrial carcinoma patients with FIGO I-II stage, middle and high differentiation, muscular layer involvement less than 1/2 and without cervical involvement; serum CA125, CA199, c-myc, sTn and ZEB1 contents of patients with endometrial carcinoma were significantly higher than those of healthy volunteers and positively correlated with serum HE4 and CP2; P53 and E-cad contents in endometrial carcinoma tissue were significantly lower than those in para-carcinoma tissue and negatively correlated with serum HE4 and CP2, and EpCAM, C-erbB-2, Ki-67 and MACC1 contents were significantly higher than those in para-carcinoma tissue and positively correlated with serum HE4 and CP2.Conclusions:Serum HE4 and CP2 contents abnormally increase in patients with endometrial carcinoma, and serum HE4 and CP2 can be used to assess the clinical pathology of tumor as well as the degree of tumor tissue proliferation.

    The charmless decays $B^{\\pm} \\rightarrow K^{+}K^{-}\\pi^{\\pm}$ and $B^{\\pm} \\rightarrow \\pi^{+}\\pi^{-}\\pi^{\\pm}$ are reconstructed in a data set, corresponding to an integrated luminosity of 1.0 fb$^{-1}$ of pp collisions at a center-of-mass energy of 7 TeV, collected by LHCb in 2011. The inclusive charge asymmetries of these modes are measured to be $A_{CP}(B^{\\pm} \\rightarrow K^{+}K^{-}\\pi^{\\pm}) =-0.141 \\pm 0.040 (stat) \\pm 0.018 (syst) \\pm 0.007 (J/\\psi K^{\\pm})$ and $A_{CP}(B^{\\pm} \\rightarrow \\pi^{+}\\pi^{-}\\pi^{\\pm}) = 0.117 \\pm 0.021 (stat) \\pm 0.009 (syst) \\pm 0.007 (J/\\psi K^{\\pm})$, where the third uncertainty is due to the CP asymmetry of the $B^{\\pm} \\rightarrow J/\\psi K^{\\pm}$ reference mode. In addition to the inclusive CP asymmetries, larger asymmetries are observed in localized regions of phase space.

  14. P,T-odd Faraday effect as a tool for observation of CP violation in Standard Model

    It is proposed to employ the P,T-odd Faraday effect, i.e. rotation of the polarization plane of the light propagating through a medium in presence of the electric field, as a tool for observation of P,T-odd effects caused by CP violation within the Standard Model. For this purpose the vapors of heavy atoms like Tl, Pb, Bi are most suitable. Estimates within the Standard Model show: provided that applied field is about 10^5 V/cm and the optical length can be as large as 70000 km, the rotation angle may reach the value corresponding to the recently observable values (10^{-9} rad). These estimates demonstrate that the P,T-odd Faraday effect observations may effectively compete with the recent measurements of the electron spin rotation in an external electric field, performed with diatomic molecules. These measurements exclude the P,T-odd effects at the level 9 orders of magnitude higher than the predictions of the Standard Model.

    A search for time-integrated $CP$ violation in the Cabibbo-suppressed decay \\mbox{$D^0\\rightarrow\\pi^+\\pi^-\\pi^+\\pi^-$} is performed using an unbinned, model-independent technique known as the energy test. This is the first application of the energy test in four-body decays. The search is performed for $P$-even $CP$ asymmetries and, for the first time, is extended to probe the $P$-odd case. Using proton-proton collision data corresponding to an integrated luminosity of 3.0~fb$^{-1}$ collected by the LHCb detector at centre-of-mass energies of $\\sqrt{s}=$7~TeV and 8~TeV, the world's best sensitivity to $CP$ violation in this decay is obtained. The data are found to be consistent with the hypothesis of $CP$ symmetry with a $p$-value of $(4.6\\pm0.5)\\%$ in the $P$-even case, and marginally consistent with a $p$-value of $(0.6\\pm0.2)\\%$ in the $P$-odd case, corresponding to a significance for $CP$ non-conservation of 2.7 standard deviations.

    Future experiments such as SHiP and high-intensity e{sup +}e{sup -} colliders will have a superb sensitivity to heavy Majorana neutrinos with masses below M{sub Z}. We show that the measurement of the mixing to electrons and muons of one such state could establish the existence of CP violating phases in the neutrino mixing matrix, in the context of low-scale seesaw models. We quantify in the minimal model the CP reach of these future experiments, and demonstrate that CP violating phases in the mixing matrix could be established at 5σ CL in a very significant fraction of parameter space.

    Jasper G van den Boorn

    Full Text Available BACKGROUND: Presently melanoma still lacks adequate treatment options for metastatic disease. While melanoma is exceptionally challenging to standard regimens, it is suited for treatment with immunotherapy based on its immunogenicity. Since treatment-related skin depigmentation is considered a favourable prognostic sign during melanoma intervention, we here aimed at the reverse approach of directly inducing vitiligo as a shortcut to effective anti-melanoma immunity. METHODOLOGY AND PRINCIPAL FINDINGS: We developed an effective and simple to use form of immunotherapy by combining the topical skin-bleaching agent monobenzone with immune-stimulatory imiquimod cream and cytosine-guanine oligodeoxynucleotides (CpG injections (MIC therapy. This powerful new approach promptly induced a melanoma antigen-specific immune response, which abolished subcutaneous B16.F10 melanoma growth in up to 85% of C57BL/6 mice. Importantly, this regimen induced over 100 days of tumor-free survival in up to 60% of the mice, and forcefully suppressed tumor growth upon re-challenge either 65- or 165 days after MIC treatment cessation. CONCLUSIONS: MIC therapy is effective in eradicating melanoma, by vigilantly incorporating NK-, B- and T cells in its therapeutic effect. Based on these results, the MIC regimen presents a high-yield, low-cost and simple therapy, readily applicable in the clinic.

    Full Text Available Cytosine-guanine oligodeoxynucleotide (CpG ODN motifs of bacterial DNA are recognized through toll-like receptor 9 (TLR9 and are potent activators of innate immunity. However, the interaction between TLR9 and CpG ODN in aquatic species has not been well characterized. Hence, cobia TLR9 isoform B (RCTLR9B was cloned and its expression and induction in intestine were investigated. RCTLR9B cDNA consists of 3113bp encoding 1009 amino acids containing three regions, leucine rich repeats, transmembrane domain, and toll/interleukin-1 receptor (TIR domain. Intraperitoneal injection of CpG ODN 2395 upregulated RCTLR9 A and B and MyD88 and also induced the expressions of Mx, chemokine CC, and interleukin IL-1β. Cobia intraperitoneally injected with CpG ODN 1668 and 2395 had increased survival rates after challenge with Photobacterium damselae subsp. piscicida. In addition, formulation of CpG ODN with formalin-killed bacteria (FKB and aluminum hydroxide gel significantly increased expressions of RCTLR9 A (50 folds and B (30 folds isoforms at 10 dpi (CpG ODN 1668 and MyD88 (21 folds at 6 dpv (CpG ODN 2395. Subsequently, IL-1β increased at 6 dpv in 1668 group. No histopathological damage and inflammatory responses were observed in the injected cobia. Altogether, these results facilitate CpG ODNs as an adjuvant to increase bacterial disease resistance and efficacy of vaccines in cobia.

    We propose a generalized $\\mu-\\tau$ reflection symmetry to constrain the lepton flavor mixing parameters. We obtain a new correlation between the atmospheric mixing angle $\\theta_{23}$ and the "Dirac" CP violation phase $\\delta_{\\rm CP}$. Only in a specific limit our proposed CP transformation reduces to standard $\\mu-\\tau$ reflection, for which $\\theta_{23}$ and $\\delta_{CP}$ are both maximal. The "Majorana" phases are predicted to lie at their CP-conserving values with important implications for the neutrinoless double beta decay rates. We also study the phenomenological implications of our scheme for present and future neutrino oscillation experiments including T2K, NO$\

    Heller, Claudio

    A feature of the neutral $B^0_s$ meson is that it can oscillate into its antiparticle before it decays, which can give rise to CP violation due to interference of the two processes mixing and decay. The time-dependent $B^0_s \\rightarrow J/\\psi\\phi$ decay is characterized by the decay width $\\Gamma_s$ and the decay width difference $\\Delta\\Gamma_s$. The $B^0_s - \\bar{B}^0_s$ oscillation is governed by the mass difference $\\Delta m_s$, and the CP violation is described by the relative phase $\\phi_s$ between the mixing and the decay. The analysis of the decay channel provides the possibility to test the predictions of the Standard Model of particle physics for those parameters. In particular the measurement of the CP violating phase $\\phi_s$ has the capability to unveil enhancement of the small Standard Model value by New Physics. In this thesis the measurement of $\\phi_s$, $\\Gamma_s$ and $\\Delta\\Gamma_s$ in the decay $B^0_s \\rightarrow J/\\psi\\phi$ is presented. The analysis makes use of an integrated luminosity...

    2015-01-01

    Objective High prevalence of erectile dysfunction (ED) was observed in patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). However, it is still unknown whether CP/CPPS is a risk factor of ED. This systematic review and meta-analysis was conducted to evaluate the relationship between CP/CPPS and ED. Methods PubMed, EMBASE, Web of Science and the Cochrane library were searched up to November 2014 to identify literatures that reported the association between CP/CPPS and ED. Case-control, cohort or cross-sectional studies were included. Newcastle-Ottawa Quality Assessment scale was used in assessing qualities of included case-control and cohort studies and an eleven item quality assessment table was used in cross-sectional studies. This meta-analysis was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses statement. Odds ratio of ED and mean difference of 5-item International Index of Erectile Function scores were pooled across studies and analyzed using random effect model. Results A total of 3 cross-sectional studies, 2 case-control studies and 4 retrospective studies with 31,956 participants were included to calculate pooled OR of ED, and 2 studies for pooled mean difference of IIEF-5 score. A strong correlation between CP/CPPS and ED (pooled OR: 3.02, 95% CI: 2.18-4.17, P<0.01) was found, with significant heterogeneity across studies (I2=65%, P<0.01). Also a significant decrease of IIFE-5 score in CP/CPPS group (pooled MD: –4.54, 95% CI: –5.11-–3.98, P<0.01) was observed. Conclusions Patients with CP/CPPS have a more increased risk of suffering from ED, but the mechanisms were unclear. Evidence of higher level is needed to further confirm this relationship. Physicians should pay more attention on erectile function of patients with CP/CPPS.

  5. CP asymmetries in singly-Cabibbo-suppressed $D$ decays to two pseudoscalar mesons

    2012-01-01

    The LHCb Collaboration has recently reported evidence for a CP asymmetry approaching the percent level in the difference between $D^0 \\to \\pi^+ \\pi^-$ and $D^0 \\to K^+ K^-$. We analyze this effect as if it is due to a penguin amplitude with the weak phase of the standard model $c \\to b \\to u$ loop diagram, but with a CP-conserving enhancement as if due to the strong interactions. In such a case the magnitude and strong phase of this amplitude $P_b$ are correlated in order to fit the observed CP asymmetry, and one may predict CP asymmetries for a number of other singly-Cabibbo-suppressed decays of charmed mesons to a pair of pseudoscalar mesons. Non-zero CP asymmetries are expected for $D^+ \\to K^+ \\ok$ (the most promising channel for which a non-zero CP asymmetry has not yet been reported), as well as $D^0 \\to \\pi^0 \\pi^0$, $D_s^+ \\to \\pi^+ \\ko$, and $D_s \\to \\pi^0 K^+$. No CP asymmetry is predicted for $D^+ \\to \\pi^+ \\pi^0$ or $D^0 \\to \\ko \\ok$ in this framework.

    The synthetic oligodeoxynucleotide CpG 7909, which contains unmethylated cytosine/guanine (CpG) motifs, has potent immunostimulatory effects when coadministered with NY-ESO-1 peptides or recombinant NY-ESO-1 protein, resulting in an enhanced cellular and humoral immune response against the vaccine antigen. In this study, we report the development of anti-CpG-ODN antibodies in 21 of 37 patients who received CpG 7909 either alone or as a vaccine adjuvant. Specific anti-CpG immunoglobulin G (IgG) antibody titers ranged from 1:400 to 1:100,000. The anti-CpG antibodies cross-reacted with other synthetic CpG-ODNs but not with the DNA of mixed bacterial vaccine and were shown to be phosphorothioate backbone specific. Vaccine-related severe side effects observed in some patients were most likely not related to the development of anti-CpG antibodies. In addition, anti-CpG antibodies did not have negative effects on the vaccine immune response. These results show that anti-CpG antibodies develop in humans against short unmethylated CpG dinucleotide sequences after administration of CpG 7909. Our data therefore substantiate the potency of CpG 7909 to directly stimulate human B-cells and suggest that anti-CpG antibody monitoring should be a part of ongoing and planned clinical trials with CpG-ODNs.

    We analyse the interplay of generalised CP transformations and the non-Abelian discrete group T′ and use the semi-direct product G{sub f}=T′⋊H{sub CP}, as family symmetry acting in the lepton sector. The family symmetry is shown to be spontaneously broken in a geometrical manner. In the resulting flavour model, naturally small Majorana neutrino masses for the light active neutrinos are obtained through the type I see-saw mechanism. The known masses of the charged leptons, lepton mixing angles and the two neutrino mass squared differences are reproduced by the model with a good accuracy. The model allows for two neutrino mass spectra with normal ordering (NO) and one with inverted ordering (IO). For each of the three spectra the absolute scale of neutrino masses is predicted with relatively small uncertainty. The value of the Dirac CP violation (CPV) phase δ in the lepton mixing matrix is predicted to be δ≅π/2 or 3π/2. Thus, the CP violating effects in neutrino oscillations are predicted to be maximal (given the values of the neutrino mixing angles) and experimentally observable. We present also predictions for the sum of the neutrino masses, for the Majorana CPV phases and for the effective Majorana mass in neutrinoless double beta decay. The predictions of the model can be tested in a variety of ongoing and future planned neutrino experiments.

    In the present study, Aluminium metal matrix composite with Al6061 matrix and SiC (10-30μm) particulate reinforcement of varying composition (2-10wt.%) were prepared by stir casting technique. Significant improvement in tensile strength and hardness was noticed as the wt.% of SiCp increases in as cast Al6061- SiC composites. The cast composites have been subjected to annealing treatment at a temperature of 400oC for 4 hours to homogenize the microstructure. The specimens have been prepared from these composites for Equal Channel Angular Pressing (ECAP). The ECAP process was carried out at room temperature using a die with channel angle of 120° and Bc route was adopted for successive passes. The effect of ECAP on the microstructure and mechanical properties of Al6061 -SiC composite is evaluated. After ECAP process, the size and distribution of the reinforcement particles are not changed but there is a significant reduction in the grain size of the matrix alloy was observed. The hardness and tension tests were conducted at room temperature as per ASTM standards. The results were compared with the base Al6061 material and as cast Al6061-SiC composites. There is a significant improvement in the hardness and the Ultimate tensile strength of ECAP processed composites.

    Selective laser melting (SLM) is an additive manufacturing technique that creates complex parts by selectively melting metal powder layer-by-layer using a laser. In SLM, the process parameters decide the quality of the fabricated component. In this study, single beads of commercially pure titanium (CP-Ti) were melted on a substrate of the same material using an in-house built SLM machine. Multiple combinations of laser power and scan speed were used for single bead fabrication, while the laser beam diameter and powder layer thickness were kept constant. This experimental study investigated the influence of laser power, scan speed, and laser energy density on the melt pool formation, surface morphology, geometry (width and height), and hardness of solidified beads. In addition, the observed unfavorable effect such as inconsistency in melt pool width formation is discussed. The results show that the quality, geometry, and hardness of solidified melt pool are significantly affected by laser power, scanning speed, and laser energy density.

    A study of the effect of cerium conversion treatment on surface of four composites (A360/SiC/10p, A360/SiC/20p, A380/SiC/10p, A380/SiC/20p) on their salt fog corrosion behaviour was performed. The conversion treatment was carried out using thermal activated full immersion in Ce(III) aqueous solutions. The matrix of A360/SiC/xxp composites is virtually free of Cu while the A380/SiC/xxp matrix contains 1.39-1.44 wt.%Ni and 3.13-3.45 wt.%Cu. Conversion performance was evaluated in neutral salt fog environment according to ASTM B117. The kinetics of the corrosion process were studied on the basis of gravimetric tests. The influence of SiCp proportion and matrix composition was evaluated and the nature of corrosion products was analysed by SEM and low angle XRD before and after accelerated testing to determine the influence of microstructural changes on corrosion behaviour during exposure to the corrosive environment. The Ce(III) precipitates on the cathodic sites, mainly on the intermetallic compounds, decreased both the cathodic current density and the corrosion rate of the composites tested. The presence of Cu in the matrix composition increased the corrosion rate, due to the galvanic couple Al/Cu. (authors)

    The effect of four macrolides against intracellular Toxoplasma gondii was determined in three different in vitro systems. Unactivated murine peritoneal macrophages were infected with the virulent RH strain of T. gondii. The activity of the macrolides was first measured with (/sup 3/H)uracil, which is incorporated by the parasite but not the host cell. The 50% inhibitory concentrations (IC50s) and 95% confidence limits were calculated at 54 (38 to 73), 140 (98 to 201), 147 (101 to 214), and 246 (187 to 325) micron for roxithromycin, azithromycin (CP-62,993), A-56268, and spiramycin, respectively. Inhibition of Toxoplasma growth was confirmed by microscopic examination of the infected macrophages after treatment with roxithromycin. Compared with untreated controls, roxithromycin concentrations near the IC50s decreased the number of infected cells, the number of tachyzoites per vacuole, and the number of cells containing rosettes (i.e., clusters of more than eight tachyzoites). After treatment with the four macrolides, tachyzoites were released from the macrophages and subcultured in HeLa cells, which are nonprofessional phagocytes, to assess the viability of the remaining parasites. This showed that the macrolides at concentrations corresponding to four times their 90% inhibitory concentrations (IC90s) had no significant killing effect. At 8 times the IC90, roxithromycin showed an incomplete killing effect, similar to that of the combination of pyrimethamine (0.41 microM)-sulfadiazine (99.42 microM). All macrolides tested showed inhibitory effects against intracellular T. gondii, but amounts of azithromycin and A-56268 corresponding to the IC90 appeared to be toxic against the host macrophages, which might have had nonspecific activity against Toxoplasma metabolism.

    HIV1-Tat-based vaccines could elicit broad, durable and neutralizing immune responses and are considered as potential AIDS vaccines. The present study aims to formulate CpG-ODNs adjuvant and Chitosan with Tat protein to enhance the immunogenicity of HIV-1-Tat-based candidate vaccines and to investigate their efficacies in mice. To this end, we added CpG-ODNs, Chitosan and Alum as adjuvants to the Tat-based candidate vaccine formulations. Then, we compared frequency and magnitude of both humoral and cellular immune responses from mice immunized with the adjuvant-formulated Tat candidate vaccines against those obtained from mice immunized with recombinant Tat protein alone. Mice were subcutaneously immunized three times at 2-week intervals with the candidate vaccines. Measurements of anti-Tat immune responses showed that all vaccinated groups had a good immunity compared to the control groups and developed high levels of both humoral and cellular responses. However, immunized mice with CpG-ODNs, and Chitosan-adjuvanted Tat vaccines elicited stronger T-cell responses (both humoral and cellular immunity) compared to the others. These data suggest that co-administration of recombinant Tat protein with CpG-ODNs and Chitosan may serve as a potential formulation for enhancing of the Tat vaccine-induced immunity and might have effects on shaping Th polarization induced by HIV1-Tat protein vaccines. © FEMS 2017.

    Plasmacytoid dendritic cells (pDCs),not only inhibit viral replication,but also play an essential role in linking the innate and adaptive immune system.In this study,we explored the effects of human immunodeficiency virus (HIV) gp120 and tat on CpG-A-induced inflammatory cytokines in pDCs.The results provided fundamental insights into HIV pathogenesis that may hold promise for preventative and even curative strategies,pDCs were isolated using blood DC antigen 4 (BDCA-4) DC isolation kit,and the purity was analyzed using BDCA-2 antibody by flow cytometry,pDCs and peripheral blood mononuclear cells (PBMCs) were stimulated by either CpG-A (5 μg/ml),gp120 (0.5 μg/ml),tat (0.5 μg/ml),or CpG-A treatment combined with gpl20 or tat.The production of type Ⅰ interferons (IFNs) and other inflammatory cytokines,including tumor necrosis factor-alpha (TNF-α),interlukine-6 (IL-6),and interferon-gammainducible protein-10 (IP-10) in the culture supernatant,was determined by enzyme-linked immunosorbent assay.The results showed that CpG-A induced high levels of type I IFNs and other inflammatory cytokines,including TNF-α,IL-6,and IP-10,in pDCs.Concomitant treatment with gp120 reduced the levels of IFN-α,IFN-β,TNF-α,IL-6,and IP-10 induced by CpG-A in pDCs by 79%,53%,60%,50%,and 34%,respectively,while tat suppressed them by 88%,66%,71%,64%,and 53%,respectively.Similar results were demonstrated in CpGA-treated PBMCs.In conclusion,gp120 and tat are effective inhibitors of the CpG-A-mediated induction of type I IFNs and other inflammatory cytokines from pDCs and PBMCs.

    This paper investigated the biodegradation kinetics of 4-chlorophenol (4-CP) and 2,4-dichlorophenol (2,4-DCP) separately in batch reactors and mixed in sequencing batch reactors (SBRs). Batch reactor experiments showed that both 4-CP and 2,4-DCP began to inhibit their own degradation at 53 and 25 mg l(-1), respectively, and that the Haldane equation gave a good fit to the experimental data because r(2) values were higher than 0.98. The maximum specific degradation rates (q(m)) were 130.3 and 112.4 mg g(-1) h for 4-CP and 2,4-DCP, respectively. The values of the half saturation (K(s)) and self-inhibition constants (K(i)) were 34.98 and 79.74 mg l(-1) for 4-CP, and 13.77 and 44.46 mg l(-1) for 2,4-DCP, respectively. The SBR was fed with a mixture of 220 mg l(-1) of 4-CP, 110 mg l(-1) of 2,4-DCP, and 300 mg l(-1) of peptone as biogenic substrate at varying feeding periods (0-8h) to evaluate the effect of feeding time on the performance of the SBR. During SBR operation, in addition to self-inhibition, 4-CP degradation was strongly and competitively inhibited by 2,4-DCP. The inhibitory effects were particularly pronounced during short feeding periods because of higher chlorophenol peak concentrations in the reactor. The competitive inhibition constant (K(ii)) of 2,4-DCP on 4-CP degradation was 0.17 mg l(-1) when the reactor was fed instantaneously (0 h feeding). During longer feedings, increased removal/loading rates led to lower chlorophenol peak concentrations at the end of feeding. Therefore, in multi-substrate systems feeding time plus reaction time should be determined based on both degradation kinetics and substrate interaction. During degradation, the meta cleavage of 4-chlorocatechol resulted in accumulation of a yellowish color because of the formation of 5-chloro-2-hydroxymuconic semialdehyde (CHMS), which was further metabolized. Isolation and enrichment of the chlorophenols-degrading culture suggested Pseudomonas sp. and Pseudomonas stutzeri to be the

    In recent years, aluminum alloy based metal matrix composites (MMC) are gaining importance in several aerospace and automobile applications. Aluminum 6061 has been used as matrix material owing to its excellent mechanical properties coupled with good formability and its wide applications in industrial sector. Addition of SiCp as reinforcement in Al6061 alloy system improves its hardness, tensile strength and wear resistance. In the present investigation Al6061–SiCp composites was fabricated by liquid metallurgy route with percentages of SiCp varying from 4 wt% to 10 wt% in steps of 2 wt%. The cast matrix alloy and its composites have been subjected to solutionizing treatment at a temperature of 530°C for 1 h followed by quenching in different media such as air, water and ice. The quenched samples are then subjected to both natural and artificial ageing. Microstructural studies have been carried out to understand the nature of structure. Mechanical properties such as microhardness, tensile strength, and abrasive wear tests have been conducted both on matrix Al6061 and Al6061–SiCp composites before and after heat treatment. However, under identical heat treatment conditions, adopted Al6061–SiCp composites exhibited better microhardness and tensile strength reduced wear loss when compared with Al matrix alloy.

    Conjugated linoleic acid (CLA) is a natural constituent of dairy products, specific isomers of which have recently been found to have insulin sensitizing and possible antiobesity actions. Chromium is a micronutrient which, as the picolinate (CrP), has been shown to increase insulin sensitivity in animal models, including the JCR:LA-cp rat. We tested the hypothesis that these agents may have beneficial synergistic effects on the micro- and macrovasculopathy associated with hyperinsulinaemia and early type 2 diabetes. Insulin-resistant cp/cp rats of the JCR:LA-cp strain were treated with mixed isomers of CLA (1.5% w/w in the chow) and/or CrP at 80 microg/kg/day (expressed as Cr) from 4 weeks of age to 12 weeks of age. Plasma insulin, lipid and adiponectin levels, aortic vascular function, renal function and glomerular sclerosis were assessed. CLA administration reduced food intake, body weight and fasting insulin in JCR:LA-cp rats. Plasma adiponectin levels were significantly elevated in rats treated with both CLA and CrP. Aortic hypercontractility was reduced and the relaxant response to the nitric oxide-releasing agent acetylcholine (Ach) was increased in CrP-treated rats. Striking reductions were also observed in the level of urinary albumin and the severity of glomerular sclerosis in rats treated specifically with CLA. CLA and CrP have beneficial effects ameliorating several of the pathophysiologic features of an insulin-resistant rat model. These supplements may be useful adjuncts in the management of patients with the metabolic syndrome and warrant further study.

    The mechanical response of a 17% (volume fraction) silicon carbide particles reinforced 2124 Al composite prepared by powder metallurgy techniques was studied by altering the matrix strength with different heat treatments. The fracture mechanisms and the deformation microstructure were examined by scanning electron microscopy. The results show that matrix strength appears to play an important role in influcing the behaviour of the composite under hardness and tensile loading conditions and also fracture mechanisms. The high matrix strength results in a larger decrease in yield strength due to the increasing damage probability. The tensile yield strength values decrease under peak aged and overaged condition whereas under the solutinized condition the opposite effect can be seen.

    Commercial pure titanium sheets were deformed by shear rolling at 400 °C with subsequent annealing to investigate microstructure and texture evolution along with its effects on the mechanical properties. A four sheet multilayer rolling scheme was used to isolate shear strains within the outer sheets, termed isolated shear rolling (ISR), thus allowing for direct comparison between shear strained material (outer sheets) and plane-strained material under similar conditions. Microstructure and texture evolution were investigated by electron backscatter diffraction analysis, while mechanical properties were evaluated through tensile testing aided by digital image correlation (DIC). Texture was seen to evolve from a ±30° transverse direction (TD) split basal texture to primarily basal texture (〈0001〉//Normal Direction) for the shear-strained sheets, in comparison with a slight rotation to a ±20° TD-split for the plane-strained sheets. After short-term annealing at 600 °C for 15 min, texture remained similar to that of the as-processed material yet at lower intensity levels. Compared to the base material, shear-rolled material showed much higher Lankford Coefficient values, with a significant boost attributed to shear deformation. The greater stretch formability is achieved in the shear-rolled material by rotation of the basal poles to become parallel to the sheet thickness. The results obtained here with ISR in regards to the effects of inducing higher shear strains on the rolled material are comparable to those reported in the literature by differential speed rolling (DSR)

    The charm quark offers interesting opportunities to cross-check the mechanism of CP violation precisely tested in the strange and beauty sectors. In this paper, we exploit the angular and quantum correlations in the D\\bar{D} pairs produced through the decay of the psi(3770) resonance in a charm factory to investigate CP-violation in two different ways. We build CP-violating observables in psi(3770) -> D\\bar{D} -> (V_1V_2)(V_3 V_4) to isolate specific New Physics effects in the charm sector. We also consider the case of psi(3770) -> D\\bar{D} -> (V_1V_2)(K\\pi) decays, which provide a new way to measure the strong phase difference delta between Cabibbo-favored and doubly-Cabibbo suppressed D decays required in the determination of the CKM angle gamma. Neglecting the systematics, we give a first rough estimate of the sensitivities of these measurements at BES-III with an integrated luminosity of 20 fb^-1 at psi(3770) peak and at a future Super tau-charm factory with a luminosity of 10^35 cm^-2.s^-1.

    Synthetic cannabinoids have been prohibited due to abuse liability and toxicity. Four such synthetic cannabinoids, AM-2201 ([1-(5-fluoropentyl)indol-3-yl]-naphthalen-1-ylmethanone), CP-47,497 (2-[(1R,3S)-3-hydroxycyclohexyl]-5-(2-methyloctan-2-yl)phenol), JWH-122 [(4-methylnaphthalen-1-yl)-(1-pentylindol-3-yl)methanone], and JWH-250 [2-(2-methoxyphenyl)-1-(1-pentylindol-3-yl)ethanone], were tested for their capacity to produce CB1 receptor-mediated discriminative stimulus effects in two groups of rhesus monkeys. One group (n = 4) discriminated Δ(9)-tetrahydrocannabinol (∆(9)-THC; 0.1 mg/kg i.v.), and a second group (n = 4) discriminated the cannabinoid antagonist rimonabant (1 mg/kg i.v.) while receiving 1 mg/kg/12 hours of ∆(9)-THC. AM-2201, JWH-122, CP-47,497, JWH-250, and ∆(9)-THC increased ∆(9)-THC lever responding. Duration of action was 1-2 hours for AM-2201, JWH-122, and JWH-250 and 4-5 hours for CP-47,497 and ∆(9)-THC. Rimonabant (1 mg/kg) surmountably antagonized the discriminative stimulus effects of all cannabinoid agonists; the magnitude of rightward shift was 10.6-fold for AM-2201, 10.7-fold for JWH-122, 11.0-fold for CP-47,497, and 15.7-fold for JWH-250. The respective pKB values were not significantly different: 6.61, 6.65, 6.66, and 6.83. In ∆(9)-THC-treated monkeys discriminating rimonabant, AM-2201 (0.1 and 0.32 mg/kg), JWH-122 (0.32 and 1 mg/kg), JWH-250 (1 and 3.2 mg/kg), and CP-47,497 (0.32, 1, and 3.2 mg/kg) produced not only rate-decreasing effects that were reversed by rimonabant, but also dose-dependent, rightward shifts in the rimonabant discrimination dose-effect function. These results show striking similarity in the CB1 receptor mechanism mediating the subjective effects of AM-2201, JWH-122, JWH-250, and CP-47,497. For products containing AM-2201 and JWH-122, a short duration of action could lead to more frequent use; moreover, inattention to differences in potency among synthetic cannabinoids could underlie unexpected

    We study a second CP symmetry compatible with the A4 flavor group, which interchanges the representations 1‧ and 1″. We analyze the lepton mixing patterns arising from the A4 and CP symmetry broken to residual subgroups Z3 and Z2 × CP in the charged lepton and neutrino sectors respectively. One phenomenologically viable mixing pattern is found, and it predicts maximal atmospheric mixing angle as well as maximal Dirac CP phase, trivial Majorana phases and the correlation sin2 ⁡θ12cos2 ⁡θ13 = 1 / 3. We construct a concrete model based on the A4 and CP symmetry, the above interesting mixing pattern is achieved, the observed charged lepton mass hierarchy is reproduced, and the reactor mixing angle θ13 is of the correct order.

So far only the channel B{sup Macron }{sub s}{sup 0}{yields}J/{psi}{phi} has been used.

A time-dependent fit of the data with the B{sup Macron }{sub s}{sup 0} lifetime and the difference in widths of the heavy and light eigenstates constrained to the values obtained from B{sup Macron }{sub s}{sup 0}{yields}J/{psi}{phi} yields a value of the CP violating phase of -0.44{+-}0.44{+-}0.02 rad, consistent with the Standard Model expectation.

The inclusive charge asymmetries of these modes are measured as $A_{C\\!P}(B^{\\pm}\\to K^{\\pm}\\pi^+\\pi^-) = 0.032 \\pm 0.008 {\\mathrm{\\,(stat)}} \\pm 0.004 {\\mathrm{\\,(syst)}} \\pm 0.007 (J/\\psi K^{\\pm})$ and $A_{C\\!P}(B^{\\pm}\\to K^{\\pm}K^+K^-) = -0.043 \\pm 0.009 {\\mathrm{\\,(stat)}} \\pm 0.003 {\\mathrm{\\,(syst)}} \\pm 0.007 (J/\\psi K^{\\pm})$, where the third uncertainty is due to the $C\\!P$ asymmetry of the $B^{\\pm}\\to J/\\psi K^{\\pm}$ reference mode. The significance of $A_{C\\!P}(B^{\\pm}\\to K^{\\pm}K^+K^-)$ exceeds three standard deviations and is the first evidence of an inclusive $C\\!P$ asymmetry in charmless three-body $B$ decays. In addition to the inclusive $C\\!P$ asymmetries, larger asymmetries are observed in localised regions of phase space.

    Establishing CP-violation in the lepton sector is one of the most challenging future tasks in neutrino physics. The lepton mixing matrix contains one Dirac phase and, if neutrinos are Majorana particles, two additional CP-violating phases. I will review the main theoretical aspects of CP-violation in the lepton sector. Then, I will present the strategies for determining the Dirac and the Majorana CP-violating phases in long-baseline and neutrinoless double beta decay experiments, respectively. Leptonic CP-violation has received recently a lot of attention as it might be at the origin of the baryon asymmetry of the Universe. Within the context of the see-saw mechanism, I will discuss the possible connection between the CP-violating phases measurable at low energy with the ones entering in leptogenesis.

  9. Renormalization group evolution of neutrino parameters in presence of seesaw threshold effects and Majorana phases

    Full Text Available We examine the renormalization group evolution (RGE for different mixing scenarios in the presence of seesaw threshold effects from high energy scale (GUT to the low electroweak (EW scale in the Standard Model (SM and Minimal Supersymmetric Standard Model (MSSM. We consider four mixing scenarios namely Tri–Bimaximal Mixing, Bimaximal Mixing, Hexagonal Mixing and Golden Ratio Mixing which come from different flavor symmetries at the GUT scale. We find that the Majorana phases play an important role in the RGE running of these mixing patterns along with the seesaw threshold corrections. We present a comparative study of the RGE of all these mixing scenarios both with and without Majorana CP phases when seesaw threshold corrections are taken into consideration. We find that in the absence of these Majorana phases both the RGE running and seesaw effects may lead to θ13<5° at low energies both in the SM and MSSM. However, if the Majorana phases are incorporated into the mixing matrix the running can be enhanced both in the SM and MSSM. Even by incorporating non-zero Majorana CP phases in the SM, we do not get θ13 in its present 3σ range. The current values of the two mass squared differences and mixing angles including θ13 can be produced in the MSSM case with tan⁡β=10 and non-zero Majorana CP phases at low energy. We also calculate the order of effective Majorana mass and Jarlskog Invariant for each scenario under consideration.

    Objective To investigate the effects of methylation status of CpG islands of endogenous E-cadherin (CDH1) gene on the promoter activity of corresponding genes in reporter assays. Methods The methylation statuses of CpG island of CDHI in 8 different cell lines were detected by methylation-specific PCR. CDH1 protein was analyzed by Western blotting. Two sets of pGL3 reporter vectors with different genotypes/haplotypes of the CDH1 promoter were constructed [pGI3-A(-73)/-C(-73)pGL3-H1/-H4]and used to transfect these cell lines. The differences between these promoter reporter vectors were analyzed by t-test. Results (1) CDH1 CpG island was unmethylated in AGS, MCF7, MKN74, and PC-3 cell lines,expressed in MCF7, MKN74, and PC-3 ,but not in AGS. Expression of CDH1 was silenced by methylation in HeLa, BGC823, A549, and RKO cell lines. (2) In the four CDH1 -unmethylated MCFT, M KN74, PC-3, and AGS cell lines ,the promoter activities of pGI3-C(-73)(as 0. 78±0. 10,0. 17±0.01,0. 11±0. 01,1.19±0. 18)were significantly higher than those of pGL3-A(-73)(as 0. 30±0. 08,0. 07±0. 01,0. 07±0. 01,0. 39±0. 04) (t values are -6. 298, -12. 349, -8. 128, -7.388, and P<0. 01). However, in the four C DH1 -methylated HeLa, BGC823, A549, and RKO cell lines, the promoter activity of pGL3-C(-73)(as 0. 09±0. 02,0. 13±0. 02,0. 05±0. 01,0. 01±0. 00) was significantly lower than that of pGL3-A(-73)(as 0. 16±0. 01,0.25±0.01,0. 11±0.03,0.03±0.00) (t valued at 5.958,11. 189,3. 661,13. 866,and P<0.05). (3) In the unmethylated MKN74 and methylated RKO cell lines, the promoter activities of pGI3-H1/-H4 were obviously and contrarily different(as 1.57±0. 23/0. 94±0. 06 and 0. 38±0. 02/0. 50±0. 04 ,t values were 4. 577 and -4. 915 ,P values were 0. 010 and 0. 003). Conclusion The methylation status of CpG island of the target gene in the tested cell lines affects the promoter activity in Reporter Assay significantly. The most active one may be the most suppressive one.%目的 研究细

  11. The physics of antineutrinos in DUNE and determination of octant and δCP

    Science.gov (United States)

    Nath, Newton; Ghosh, Monojit; Goswami, Srubabati

    2016-12-01

    The octant of the leptonic mixing angle θ23 and the CP phase δCP are the two major unknowns (apart from neutrino mass hierarchy) in neutrino oscillation physics. It is well known that the precise determination of octant and δCP is interlinked through the octant-δCP degeneracy. In this paper we study the proficiency of the DUNE experiment to determine these parameters scrutinizing, in particular, the role played by the antineutrinos, the broadband nature of the beam and the matter effect. It is well known that for Pμe and P μ bar e bar the octant-δCP degeneracy occurs at different values of δCP, combination of neutrino and antineutrino runs help to resolve this. However, in regions where neutrinos do not have octant degeneracy adding antineutrino data is expected to decrease the sensitivity because of the degeneracy and reduced statistics. However we find that in case of DUNE baseline, the antineutrino runs help even in parameter space where the antineutrino probabilities suffer from degeneracies. We explore this point in detail and point out that this happens because of the (i) broad-band nature of the beam so that even if there is degeneracy at a particular energy bin, over the whole spectrum the degeneracy may not be there; (ii) the enhanced matter effect due to the comparatively longer baseline which creates an increased tension between the neutrino and the antineutrino probabilities which raises the overall χ2 in case of combined runs. This feature is more prominent for IH since the antineutrino probabilities in this case are much higher than the neutrino probabilities due to matter effects. The main role of antineutrinos in enhancing CP sensitivity is their ability to remove the octant-δCP degeneracy. However even if one assumes octant to be known the addition of antineutrinos can give enhanced CP sensitivity in some parameter regions due to the tension between the neutrino and antineutrino χ2s.

    Nitrogen ion implantation is one of the surface modification techniques used for increasing corrosion resistance of commercially pure titanium (CpTi). The nitrogen ion implanted CpTi in various doses markedly changes the corrosion resistance. Still the effect of nitrogen ion implantation on the CpTi at different energies needs to be verified. This study uses different methods to assess the CpTi surface properties after nitrogen ion implantation in various doses and energy. Surface hardness of the CpTi increases with an increase of the dose and decreases with an increase of the energy. The precipitation of the TiN increases with an increase of the nitrogen dose, and no formation of the Ti2N phase clearly appears. Corrosion resistance of the CpTi specimens can be upgraded to some extent after their surfaces are modified, implanting nitrogen ions at 100 keV by increasing dose. The optimum surface properties of the implanted CpTi are analyzed to contribute to materials science technology.

    Oligodeoxynucleotide containing unmethylated cytosine phosphate- guanosine motif(CpG ODN) may induce high expression of CD80, CD86, CD83, HLA Ⅰ and HLA Ⅱ molecules on dendritic cells(DC) and stimulate DC to produce highlevel of IL-6, IL-12, TNF-α and IFN-α. CpG ODN is demonstrated in vivo to be a very potent adjuvant for Thl cells, regulating Th0 cells to develop toward Thl cells. Its role for DC is characteristics of CpG ODN sequence specificity and species specificity. CpG ODN is, at present, considered as a pathogen associated molecular pattern which binds its specific receptor,Toll-like receptor 9, then functions through TLR/IL-1R signaling pathway. It may represent a new therapeutic drug for broad applications in infectious disease, autoimmune disease, allergy and cancer therapy.

  14. Possible complex annihilation and B -> K pi direct CP asymmetry

    2007-01-01

    We point out that a sizable strong phase could be generated from the penguin annihilation in the soft-collinear effective theory for B meson decays. Keeping a small scale suppressed by O(Lambda/m_b), Lambda being a hadronic scale and m_b the b quark mass, in the denominators of internal particle propagators without expansion, the resultant strong phase can accommodate the data of the B^0 -> K^+- pi^+- direct CP asymmetry. Our study reconciles the opposite conclusions on the real or complex penguin annihilation amplitude drawn in the soft-collinear effective theory and in the perturbative QCD approach based on k_T factorization theorem.

    Nath, Newton; Goswami, Srubabati

    2016-01-01

    We study the efficiency of DUNE, a next generation long baseline oscillation experiment to resolve two major unknowns in neutrino oscillation physics. These are, octant of $\\theta_{23}$ (i.e. if $\\theta_{23}$ is $45^\\circ$) and Dirac CP phase $\\delta_{CP}$. We mainly focus on the role of antineutrinos when they travel 1300 km baseline of DUNE. We observe that for DUNE, the antineutrino runs help to remove parameter degeneracies even in the parameter space where the antineutrino probability suffers from various degeneracies. We study these points in detail and find that, due to enhanced matter effect longer baseline experiments create an increased tension between the neutrino and the antineutrino probabilities which helps to increase total sensitivity in case of combined runs. We also find that, antineutrino run increases overall CP sensitivity due to its ability to abolish octant-$\\delta_{CP}$ degeneracy.

    2014-06-01

    Full Text Available The introduction of chirality, i.e., the lack of mirror symmetry, has a profound effect on liquid crystals, not only on the molecular scale but also on the supermolecular scale and phase. I review these effects, which are related to the formation of supermolecular helicity, the occurrence of novel thermodynamic phases, as well as electro-optic effects which can only be observed in chiral liquid crystalline materials. In particular, I will discuss the formation of helical superstructures in cholesteric, Twist Grain Boundary and ferroelectric phases. As examples for the occurrence of novel phases the Blue Phases and Twist Grain Boundary phases are introduced. Chirality related effects are demonstrated through the occurrence of ferroelectricity in both thermotropic as well as lyotropic liquid crystals. Lack of mirror symmetry is also discussed briefly for some biopolymers such as cellulose and DNA, together with its influence on liquid crystalline behavior.

  18. Nonthermal CP Violation in Soft Leptogenesis

    Adhikari, Rathin; Fong, Chee Sheng; Rangarajan, Raghavan

    2015-01-01

    Soft leptogenesis is a mechanism which generates the matter-antimatter asymmetry of the Universe via the out-of-equilibrium decays of heavy sneutrinos in which soft supersymmetry breaking terms play two important roles: they provide the required CP violation and give rise to the mass splitting between otherwise degenerate sneutrino mass eigenstates within a single generation. This mechanism is interesting because it can be successful at lower temperature regime $T \\lesssim 10^9$ GeV in which the conflict with the overproduction of gravitinos can possibly be avoided. In earlier works the leading CP violation is found to be nonzero only if finite temperature effects are included. By considering generic soft trilinear couplings, we find two interesting consequences: 1) the leading CP violation can be nonzero even at zero temperature realizing nonthermal CP violation and 2) the CP violation is sufficient even far away from the resonant regime allowing soft supersymmetry breaking parameters to assume natural value...

  19. The Effects of Maternal Separation on Adult Methamphetamine Self-Administration, Extinction, Reinstatement, and MeCP2 Immunoreactivity in the Nucleus Accumbens

    2013-06-01

    Full Text Available The maternal separation (MS paradigm is an animal model of early life stress. Animals subjected to MS during the first two weeks of life display altered behavioral and neuroendocrinological stress responses as adults. MS also produces altered responsiveness to and self-administration (SA of various drugs of abuse including cocaine, ethanol, opioids, and amphetamine. Methamphetamine (METH causes great harm to both the individual user and to society; yet, no studies have examined the effects of MS on METH SA. This study was performed to examine the effects of MS on the acquisition of METH SA, extinction, and reinstatement of METH-seeking behavior in adulthood. Given the known influence of early life stress and drug exposure on epigenetic processes, group differences in levels of the epigenetic marker methyl CpG binding protein 2 (MeCP2 in the nucleus accumbens (NAc core were also investigated. Long-Evans pups and dams were separated on postnatal days (PND 2-14 for either 180 (MS180 or 15 min (MS15. Male offspring were allowed to acquire METH SA (0.05 mg/kg/infusion in 15 2-hr daily sessions starting at PND67, followed by extinction training and cue-induced reinstatement of METH-seeking behavior. Rats were then assessed for MeCP2 levels in the NAc core by immunohistochemistry. The MS180 group self-administered significantly more METH and acquired SA earlier than the MS15 group. No group differences in extinction or cue-induced reinstatement were observed. MS15 rats had significantly elevated MeCP2-immunoreactive cells in the NAc core as compared to MS180 rats. Together, these data suggest that MS has lasting influences on METH SA as well as epigenetic processes in the brain reward circuitry.

  20. Flavour physics and CP violation

    It is well known that the study of flavour physics and CP violation is very important to critically test the Standard Model and to look for possible signature of new physics beyond it. The observation of CP violation in kaon system in 1964 has ignited a lot of experimental and theoretical efforts to understand its origin and to look for CP violation effects in other systems besides the neutral kaons. The two -factories BABAR and BELLE, along with other experiments, in the last decade or so made studies in flavour physics and CP violation a very interesting one. In this article we discuss the status and prospectives of the flavour physics associated with the strange, charm and bottom sectors of the Standard Model. The important results in kaon sector will be briefly discussed. Recently, mixing in the charm system has been observed, which was being pursued for quite some time without any success. The smallness of the mixing parameters in the charm system is due to the hierarchical structure of the CKM matrix. Interestingly, so far we have not found CP violation in the charm system but in the future, with more dedicated experiments at charm threshold, the situation could change. Many interesting observations have been made in the case of bottom mesons and some of them show some kind of deviations from that of the Standard Model expectations which are mainly associated with the → flavour changing neutral current transitions. It is long believed that the system could be the harbinger of new physics since it is a system in which both bottom and strange quarks are the constituents. Recently, D0 and CDF announced their result for the mixing which is claimed to be the first possible new physics signature in the flavour sector. We plan to touch upon all important issues pointing out both theoretical and experimental developments and future prospects in this review article.

    We report the development of a DNA vaccine pcMGNNV2 against nervous necrosis virus (NNV), a leading cause of mass mortality in grouper larvae. In addition, the modulatory effect of CpG oligodeoxynucleotide (ODN), a Toll-like receptor 9 agonist, on the DNA vaccine was evaluated. The DNA vaccine alone elicited the production of NNV-specific antibodies, indicating that the vaccine was capable of triggering adaptive humoral response. Furthermore, significant induction of TLR9, Mx and IL-1β was observed in the spleen on day 7 post-vaccination, supporting that the vaccine could trigger TLR9 signaling. The incorporation of CpG ODN at high dose did not significantly affect the level of NNV-specific antibodies, but was able to moderately enhance the expression of Mx and IL-1β on day 7, indicating its ability in modulating innate response. After challenge with NNV, the vaccine alone enhanced the survival rate in infected larvae at both 1 and 2 weeks post-vaccination. The combination of CpG ODN further increased the survival rate at week 1 but not week 2. Interestingly, at week 2 the ODN appeared to induce a Th1-like response, as indicated by upregulation of T-bet (a Th1 marker) and downregulation of GATA-3 (a Th2 marker). Thus, the results suggest that the boosted Th1 response by CpG ODN does not augment the protection efficacy of pcMGNNV2 vaccine. To our best knowledge, this is the first report of a successful DNA vaccine against NNV in grouper.

    In the CP-violating Minimal Supersymmetric Standard Model, we study the production of a neutralino-chargino pair at the LHC. For their decays into three leptons, we analyze CP asymmetries which are sensitive to the CP phases of the neutralino and chargino sector. We present analytical formulas for the entire production and decay process, and identify the CP-violating contributions in the spin correlation terms. This allows us to define the optimal CP asymmetries. We present a detailed numerical analysis of the cross sections, branching ratios, and the CP observables. For light neutralinos, charginos, and squarks, the asymmetries can reach several 10%. We estimate the discovery potential for the LHC to observe CP violation in the trilepton channel.

    We revisit the effect of the (Dirac) CP-violating phase on neutrino lepton number asymmetries in both mass- and flavor-basis. We found that, even if there are sizable effects on muon- and tau-neutrino asymmetries, the effect on the asymmetry of electron-neutrinos is at most similar to the upper bound set by BBN for initial neutrino degeneracy parameters smaller than order unity. We also found that, for the asymmetries in mass-basis, the changes caused by CP-violation is of sub-\\% level which is unlikely to be accesible neither in the current nor in the forthcoming experiments.

    The Next-to-Minimal Supersymmetric extension of the Standard Model (NMSSM) features extra new sources for CP violation. In contrast to the MSSM CP violation can already occur at tree level in the Higgs sector. We investigate the range of possible allowed CP-violating phases by taking into account the constraints arising from the measurements of the Electric Dipole Moments (EDMs) and the latest LHC Higgs data. Our analysis shows that large CP-violating phases, that are NMSSM-specific, are not in conflict with the EDMs. They are dominantly constrained by the Higgs data in this case. We use our results to investigate the prospects of measuring CP violation through the combined measurement of Higgs rates, on the one hand, and in observables based on CP-violating Higgs couplings to tau leptons on the other hand.

  13. Sensitivity of the baryon asymmetry produced by leptogenesis to low energy CP violation

    2007-01-01

    If the baryon asymmetry of the Universe is produced by leptogenesis, CP violation is required in the lepton sector. In the seesaw extension of the Standard Model with three hierarchical right-handed neutrinos, we show that the baryon asymmetry is insensitive to the PMNS phases: thermal leptogenesis can work for any value of the observable phases. This result was well-known when there are no flavour effects in leptogenesis; we show that it remains true when flavour effects are included.

    CP violation is intimately connected with the puzzle of matter-antimatter asymmetry and baryogenesis. In the Standard Model of particle physics, the observed CP violation phenomena are accounted for by the Cabibbo-Kobayashi-Maskawa mechanism involving a phase in the quark mixing matrix. This paper is devoted to a review of the experimental status of CP violation in the decays of B mesons.

    Recently, several invasive mealybugs (Hemiptera: Pseudococcidae) have rapidly spread to Asia and have become a serious threat to the production of cotton including transgenic cotton. Thus far, studies have mainly focused on the effects of mealybugs on non-transgenic cotton, without fully considering their effects on transgenic cotton and trophic interactions. Therefore, investigating the potential effects of mealybugs on transgenic cotton and their key natural enemies is vitally important. A first study on the effects of transgenic cotton on a non-target mealybug, Ferrisia virgata (Cockerell) (Hemiptera: Pseudococcidae) was performed by comparing its development, survival and body weight on transgenic cotton leaves expressing Cry1Ac (Bt toxin) + CpTI (Cowpea Trypsin Inhibitor) with those on its near-isogenic non-transgenic line. Furthermore, the development, survival, body weight, fecundity, adult longevity and feeding preference of the mealybug predator Cryptolaemus montrouzieri Mulsant (Coleoptera: Coccinellidae) was assessed when fed F. virgata maintained on transgenic cotton. In order to investigate potential transfer of Cry1Ac and CpTI proteins via the food chain, protein levels in cotton leaves, mealybugs and ladybirds were quantified. Experimental results showed that F. virgata could infest this bivalent transgenic cotton. No significant differences were observed in the physiological parameters of the predator C. montrouzieri offered F. virgata reared on transgenic cotton or its near-isogenic line. Cry1Ac and CpTI proteins were detected in transgenic cotton leaves, but no detectable levels of both proteins were present in the mealybug or its predator when reared on transgenic cotton leaves. Our bioassays indicated that transgenic cotton poses a negligible risk to the predatory coccinellid C. montrouzieri via its prey, the mealybug F. virgata.

    Recent results on CP-violation measurements in decays from energy asymmetric -factory experiments are reported. Thanks to large accumulated data samples, CP-violations in decays in mixing-decay interference and direct CP-violation are now firmly established. The measurements of three angles of the unitarity triangle from CP-violations of decays are quite consistent with the Standard Model expectations. These results strongly support the validity of the Kobayashi-Maskawa prescription of CP-violation.

    The production characteristics of wells in the northwestern Cerro Prieto III area changed greatly when the Cp-III power plant went on line in 1986. Fluid extraction in the field more than doubled and reservoir-wide boiling started immediately, greatly increasing the enthalpy of produced fluids. Some well fluids showed a decrease in chloride due to adiabatic steam condensation in the well and separator, and others were enriched in chloride due to boiling. As reservoir drawdown increased, entrance of cooler and more dilute groundwaters into the reservoir became evident (i.e., condensation stopped, and there was a decrease in enthalpy and chloride in produced fluids). Although some groundwater inflow was from the leaky western margin of the reservoir, the majority is in the northeast, inferred to be local and downward, possibly through more permeable zones associated with the normal fault H. This natural recharge and some reinjection have slowed and possibly reversed pressure drawdown throughout CP-III. Enthalpy has decreased and liquid saturation has increased as the steam-rich zone in the upper part of the reservoir has either disappeared or become thinner.

    Direct measurements of the angles of the Cabibbo-Kobayashi-Maskawa (CKM) unitarity triangle will be possible at the B-factories now being commissioned. The physics potential of the ATLAS experiment which will be a general purpose experiment at LHC to determine CP violation parameters from measurement of neutral B-meson decays is discussed. An estimation of the error in sin2 beta is presented for three years of running (corresponding to 30fb/sup -1/) based on reconstruction of the decay channel B/sub d//sup 0/ to J/ psi K/sub S //sup 0/ using two tagging methods. To determine the asymmetry that is due to CP violation, the asymmetry due to different production probabilities of B/sub d//sup 0/ and B/sub d//sup 0/ in pp collisions has to be subtracted from the measured asymmetry. The accuracy with which this production asymmetry can be measured has been estimated using the two control channels B/sub d//sup 0/ to J/ psi K/sup 0/* and B/sub d//sup 0/ to J/ psi K/sup +/.

    Previous studies have suggested a role for both CB1 and CB2 cannabinoid receptors in modulation of nociception. To further examine the role of CB1 and CB2 receptors in antinociception, we evaluated the efficacy of the non-selective cannabinoid receptor agonist, CP 55,940, in models of acute, inflammatory, and neuropathic pain in control mice, CB1 receptor knockout mice, and CB2 receptor knockout mice. In control C57BL/6 mice, administration of CP 55,940 (0.03-0.3 mg/kg, i.p.) reversed complete Freund's adjuvant-induced tactile allodynia, reversed tactile allodynia in the spinal nerve ligation model and inhibited the noxious heat-evoked tail withdrawal response. In addition to its antinociceptive effects, CP 55,940 produced an impairment of motor coordination in the rotarod test. The antinociceptive effects produced by CP 55,940 and associated motor deficits were found to be completely abolished in CB1 receptor knockout mice. In contrast, the antinociceptive effects of CP 55,940 in all pain models were fully retained in CB2 receptor knockout mice, along with the associated motor deficits. The results suggest that the antinociceptive effects of CP 55,940 in models of acute and persistent pain, along with the associated motor deficits, are mediated by CB1 receptors, and likely not CB2 receptors.

    We present the first evidence of CP violation in the B+→ pi+pi-pi+,  B+→ K+pi+pi-, B+→ K+K-pi+ and B+→K+K-K+ decays using the 1.0 fb-1 of data collected by the LHCb experiment during 2011. The results show that the 3pi and Kpipi channels present a positive asymmetry while the KKpi and KKK modes present a negative asymmetry. We also study the variation of the CP violation effects in the phase space of each three-body decay.  We find significant inhomogeneities that reveal regions with particularly large asymmetries in the pipi and KK low mass regions in B+→pi+pi-pi+ and B+→K+K-pi+ respectively.

    Regularization of quantum field theories (QFT's) can be achieved by quantizing the underlying manifold (spacetime or spatial slice) thereby replacing it by a non-commutative matrix model or a ``fuzzy manifold''. Such discretization by quantization is remarkably successful in preserving symmetries and topological features, and altogether overcoming the fermion-doubling problem. In this paper, we report on our work on the ``fuzzification'' of the four-dimensional CP2 and its QFT's. CP2 is not spin, but spin${}_c$. Its Dirac operator has many unique features. They are explained and their fuzzy versions are described.

    A width difference of the order of 20\\% has previously been predicted for the two mass eigenstates of the B_s meson. The dominant contributor to the width difference is the b\\rightarrow c\\bar c s transition, with final states common to both B_s and \\overline{B}_s. All current experimental analyses fit the time-dependences of flavor-specific B_s-modes to a single exponential, which essentially determines the average B_s lifetime. We stress that the same data sample allows even the measurement of the width difference. To see that, this note reviews the time-dependent formulae for tagged B_s decays, which involve rapid oscillatory terms depending on \\Delta mt. In untagged data samples the rapid oscillatory terms cancel. Their time-evolutions depend only on the much more slowly varying exponential falloffs. We discuss in detail the extraction of the two widths, and identify the large (small) CP-even (-odd) rate with that of the light (heavy) B_s mass eigenstate. It is demonstrated that decay length distributions ...

    We report an updated measurement of the CP-violating phase, {phi}{sub s}{sup J/{psi}{phi}} and the decay-width difference for the two mass eigenstates, {Delta}{Gamma}{sub s}, from the flavor-tagged decay B{sub s}{sup 0} {yields} J/{psi}{phi}. The data sample corresponds to an integrated luminosity of 8.0 fb{sup -1} accumulated with the D0 detector using p{bar p} collisions at {radical}s = 1.96 TeV produced at the Fermilab Tevatron collider. The 68% Bayesian credibility intervals, including systematic uncertainties, are {Delta}{Gamma}{sub s} = 0.163{sub -0.064}{sup +0.065} ps{sup -1} and {phi}{sub s}{sup J}/{psi}{phi} = -0.55{sub -0.36}{sup +0.38}. The p-value for the Standard Model point is 29.8%.

    2008-01-01

    We measure the CP-violating asymmetries in decays to the D0 -> K+K- and D0 -> pi+pi- CP eigenstates using 540 fb^{-1} of data collected with the Belle detector at or near the Upsilon(4S) resonance. Cabibbo-favored D0 -> K-pi+ decays are used to correct for systematic detector effects. The results, A_{CP}^{KK} = (-0.43 +- 0.30 +- 0.11)% and A_{CP}^{pipi} = (+0.43 +- 0.52 +- 0.12)%, are consistent with no CP violation.

  8. The B-CP Puzzles in QCD Factorization

    2010-01-01

    Within the framework of QCD factorization (QCDF), power corrections due to penguin annihilation can account for theobserved rates of penguin-dominated two-body decays of $B$ mesons and direct CP asymmetries $A_{CP}(K^-\\pi^+)$, $A_{CP}((K^{*-}\\pi^+)$, $A_{CP}((K^-\\rho^0)$ and $A_{CP}((\\pi^+\\pi^-)$. However, the predicted direct CP-violating effects in QCDF for $B^-\\to K^-\\pi^0,K^-\\eta,\\pi^-\\eta$ and $\\bar B^0\\to\\pi^0\\pi^0$ are wrong in signs when confronted with experiment. We consider two different types of power correction effects in order to resolve the CP puzzles and rate deficit problems with penguin-dominated two-body decays of $B$ mesons and color-suppressed tree-dominated $\\pi^0\\pi^0$ and $\\rho^0\\pi^0$ modes: penguin annihilation and soft corrections to the color-suppressed tree amplitude.

    2009-01-01

    We study the potential to observe CP-violating effects in SUSY cascade decay chains at the LHC. We consider squark and gluino production followed by subsequent decays into neutralinos with a three-body leptonic decay in the final step. Asymmetries composed by triple products of momenta of the final state particles are sensitive to CP-violating effects. Due to large boosts these asymmetries can be difficult to observe at a hadron collider. We show that using all available kinematic information one can reconstruct the decay chains on an event-by-event basis even in the case of 3-body decays, neutrinos and LSPs in the final state. We also discuss the most important experimental effects like major backgrounds and momentum smearing due to finite detector resolution. We show that with 300 fb$^{-1}$ of collected data, CP violation may be discovered at the LHC for a wide range of the phase of the bino mass parameter $M_1$.

    We exploit the angular and quantum correlations in the $D\\bar{D}$ pairs produced through the decay of the $\\psi(3770)$ resonance in a charm factory to investigate CP-violation in two different ways. We consider the case of $\\psi(3770)\\rightarrow D\\bar{D}\\rightarrow (V_1V_2)(K\\pi)$ decays, which provide a new way to measure the strong phase difference $\\delta$ between Cabibbo-favored and doubly-Cabibbo suppressed $D$ decays required in the determination of the CKM angle $\\gamma$. We also build CP-violating observables in $\\psi(3770)\\rightarrow D\\bar{D}\\rightarrow (V_1V_2)(V_3 V_4)$ to isolate specific new physics effects in the charm sector. Neglecting the systematics, we give a first rough estimate of the sensitivities of these measurements at BES-III with an integrated luminosity of 20 fb$^{-1}$ at $\\psi(3770)$ peak and at a future super $\\tau$-charm factory with a luminosity of $10^{35}$ cm$^{-2}$s$^{-1}$

    In humans, impulsivity measured as false alarms in a Go/No-Go task is reportedly decreased by amphetamine and is not affected by oxycodone and delta(9)-tetrahydrocannabinol. To model these findings in animals, three rhesus monkeys were trained to perform a food-reinforced Go/No-Go task. In this task, amphetamine was found to decrease false alarms (i.e. responding during No-Go trials), but only at doses that also decreased hits (i.e. responding during Go trials). Morphine generally decreased hits but not false alarms. The cannabinoid receptor agonist CP 55, 940 decreased both false alarms and hits, but only at doses that also decreased the number of trials completed. Additional studies in animals and humans are necessary to delineate the conditions under which amphetamine and other psychoactive drugs affect impulsivity in Go/No-Go tasks.

    Full Text Available Lung cancer is the leading cause of cancer deaths worldwide. Expression of the p53 tumor suppressor protein is frequently altered in tobacco-associated lung cancers. We studied chemopreventive effects of p53-modulating agents, namely, CP-31398 and Prima-1, on 4-(methylnitrosamino-1-(3-pyridyl-1-butanone (NNK-induced lung adenoma and adenocarcinoma formation in female A/J mice. Seven-week-old mice were treated with a single dose of NNK (10 µmol/mouse by intraperitoneal injection and, 3 weeks later, were randomized to mice fed a control diet or experimental diets containing 50 or 100 ppm CP-31398 or 150 or 300 ppm Prima-1 for either 17 weeks (10 mice/group or 34 weeks (15 mice/group to assess the efficacy against lung adenoma and adenocarcinoma. Dietary feeding of 50 or 100 ppm CP-31398 significantly suppressed (P < .0001 lung adenocarcinoma by 64% and 73%, respectively, after 17 weeks and by 47% and 56%, respectively, after 34 weeks. Similarly, 150 or 300 ppm Prima-1 significantly suppressed (P < .0001 lung adenocarcinoma formation by 56% and 62%, respectively, after 17 weeks and 39% and 56%, respectively, after 34 weeks. Importantly, these results suggest that both p53 modulators cause a delay in the progression of adenoma to adenocarcinoma. Immunohistochemical analysis of lung tumors from mice exposed to p53-modulating agents showed a significantly reduced tumor cell proliferation and increased accumulation of wild-type p53 in the nucleus. An increase in p21- and apoptotic-positive cells was also observed in lung tumors of mice exposed to p53-modulating agents. These results support a chemopreventive role of p53-modulating agents in tobacco carcinogen-induced lung adenocarcinoma formation.

    Latest LHCb measurements of $CP$ violation in b-hadrons are presented based on $pp$ collision data collected in 2011 and 2012 at centre-of-mass energies of $\\sqrt{s}=7$ $\\rm TeV$ and $8\\ \\rm TeV$ respectively. The total integrated luminosity collected is 3.0 fb$^{-1}$. Results include recent measurements of $CP$ violation in $B_d$ and $B_s$ mixing, along with those of quantifying the effects of $b\\to c\\bar{c} s$ loop pollution. Standard Model $CP$ violation tests in loop transitions are discussed with results consistent with expectations.

    Non-conservation of CP symmetry can manisfest itself in non-leptonic hyperon decays as a difference in the decay parameter between the strange-baryon decay and its charge conjugate. By comparing the decay distribution in the $\\Lambda$ helicity frame for the decay sequence $\\Xi^{-} \\to \\Lambda \\pi^{-}$, $\\Lambda \\to p \\pi^{-}$ with that of $\\bar{\\Xi}^{+}$ decay, E756 at Fermilab did not observe any CP-odd effect at the $10^{-2}$ level. The status of a follow-up experiment, HyperCP (FNAL E871), to search for CP violation in charged $\\Xi-\\Lambda$ decay with a sensitivity of $10^{-4}$ is also presented.

    Within the extension of MSSM by two right handed neutrinos, which masses are degenerate at tree level, we address the issue of leptogenesis. Investigating the quantum corrections in details, we show that the lepton asymmetry is induced at 1-loop level and decisive role is played by the tau lepton Yukawa coupling. On a concrete and predictive neutrino model, which enables to predict the CP violating $\\delta $ phase and relate it to the cosmological CP asymmetry, we demonstrate that the needed amount of the baryon asymmetry is generated via the resonant leptogenesis.

    2015-01-01

    We revisit the topic of triple-product asymmetries which probe CP violation through differential distributions. We construct distributions with well-defined discrete symmetry properties and characterize the asymmetries formed upon them. It is stressed that the simplest asymmetries may not be optimal. We explore systematic generalizations having limited reliance on the process dynamics and phase-space parametrization. They exploit larger fractions of the information contained in differential distributions and may lead to increased sensitivities to CP violation. Our detailed treatment of the case of spinless four-body decays paves the way for further experimental studies.

Direct implications for the dynamics of phase conversion and its time scales are briefly discussed. Our results can also be relevant in the case of the early universe.

    Full Text Available Allergic Rhinitis (AR is one of the most common chronic diseases in the developed countries. This study was performed to investigate the effect of CpG-ODN in alteration of T-helper (Th1/Th2 balance of patients with AR treated with intranasal corticosteroids (INCs and antihistamines. Peripheral blood mononuclear cells (PBMCs of 20 patients with AR were isolated before and after 45 days therapy.Cytokine production (IL-4, IL-10, IL-13, IFN-γ and specific Ch.a IgE in response to CpG co- administration  of  natural  chenopodium  album  (CpG/Ch.a  or  recombinant  Ch.a  (CpG/rCh.a allergen were investigated in supernatants.of cultured PBMCs using ELISA Intracellular IL-10 was also assessed in CD4+ cells using flow cytometry. Significant increase in production of IFN-γ and IL-10 and decrease in production of IL-4 were found in supernatants of cultured PBMCs activated with CPG/ch.a and CPG/rch.a. of both CpG/Ch.a and CpG/rCh.a compared to allergens alone, before and after therapy.After therapy, IFN-γ production with CpG/Ch.a was significantly increased in comparison with before (237 vs. 44 pg/ml, p=0.001. IFN-γ and IL-10 production with CpG/rCh.a was significantly increased after therapy compared to before (407.6 vs. 109 pg/ml, p=0.01 for IFN-γ; 171.7 vs. 52.6 pg/ml, p=0.008  for  IL-10,  whilst  IL-4  was  significantly decreased (2.1  vs.  5.8  pg/ml,  p=0.02. Intracellular IL-10 expression was also significantly increased in response to either CpG/Ch.a or CpG/rCh.a that showed intracellular assay could be more sensitive than ELISA. Also, treatment with intranasal corticosteroids and antihistamines could enhance this CpG effect, in vitro.

    We consider the modification of the Cahn-Hilliard equation when a time delay process through a memory function is taken into account. We then study the process of spinodal decomposition in fast phase transitions associated with a conserved order parameter. Finite-time memory effects are seen to affect the dynamics of phase transition at short times and have the effect of delaying, in a significant way, the explosive spinodal decomposition. These effects are important in several systems characterized by fast processes, like nonequilibrium dynamics in the early universe and in relativistic heavy-ion collisions.

    CpG-oligodeoxyribonucleotides (CpG-ODNs), which induce signaling through the toll-like receptor 9, are currently under investigation as immunity stimulators against cancer. It has recently been suggested that CpG-ODNs may also enhance sensitivity to traditional therapies including chemotherapy in certain cancer-cell lines. The purpose of this study was to define the activity of CpG-ODN7909 in increasing radiosensitivity of the human non-small cell lung cancer cell line A549 in vitro. First, a dose- and time-dependent inhibitory effect on cell viability was observed after A549 cells were treated with different concentrations of CpG-ODN7909 (5, 10, 30, and 60 microg/mL). Second, decreased cell clonogenic survival, enhanced cell apoptotic index, accumulated percentage of cells in the G2/M phase, and increased tumor necrosis factor (TNF)-alpha secretion were found after combined treatments with 10 microg/mL of CpG-ODN7909 and radiation compared to either treatment alone (p CpG-ODN7909 can increase the radiosensitivity of human non-small cell lung cancer A549 cells, which may be associated with reduced cell clonogenic survival, enhanced apoptosis, prolonged cell-cycle arrest in G2/M, and stimulation of TNF-alpha secretion.

    Xing, Zhi-zhong; Zhu, Jing-yu

    2016-07-01

    Given an accelerator-based neutrino experiment with the beam energy E ≲ 1 GeV, we expand the probabilities of ν μ → ν e and {overline{ν}}_{μ}to {overline{ν}}_e oscillations in matter in terms of two small quantities Δ21 /Δ31 and A/Δ31, where Δ 21≡ m 2 2 - m 1 2 and Δ 31≡ m 3 2 - m 1 2 are the neutrino mass-squared differences, and A measures the strength of terrestrial matter effects. Our analytical approximations are numerically more accurate than those made by Freund in this energy region, and thus they are particularly applicable for the study of leptonic CP violation in the low-energy MOMENT, ESS νSM and T2K oscillation experiments. As a by-product, the new analytical approximations help us to easily understand why the matter-corrected Jarlskog parameter tilde{J} peaks at the resonance energy E ∗ ≃ 0 .14GeV (or 0 .12 GeV) for the normal (or inverted) neutrino mass hierarchy, and how the three Dirac unitarity triangles are deformed due to the terrestrial matter contamination. We also affirm that a medium-baseline neutrino oscillation experiment with the beam energy E lying in the E ∗ ≲ E ≲ 2 E ∗ range is capable of exploring leptonic CP violation with little matter-induced suppression.

    CERN Document Server

    Beard, B B; Riederer, S; Wiese, U J

    2005-01-01

    D-theory provides an alternative lattice regularization of the (1+1)-d CP(N-1) quantum field theory. In this formulation the continuous classical CP(N-1) fields emerge from the dimensional reduction of discrete SU(N) quantum spins. In analogy to Haldane's conjecture, ladders consisting of an even number of transversely coupled spin chains lead to a CP(N-1) model with vacuum angle \\theta = 0, while an odd number of chains yields \\theta = \\pi. In contrast to Wilson's formulation of lattice field theory, in D-theory no sign problem arises at \\theta = \\pi, and an efficient cluster algorithm is used to investigate the \\theta-vacuum effects. At \\theta = \\pi there is a first order phase transition with spontaneous breaking of charge conjugation symmetry for CP(N-1) models with N>2.

    Cannabinoids suppress neuropathic pain through activation of cannabinoid CB1 and/or CB2 receptors; however, unwanted CB1-mediated cannabimimetic effects limit clinical use. We asked whether CP55,940 [(-)-3-[2-hydroxy-4-(1,1-dimethylheptyl)phenyl]-4-(3-hydroxypropyl)cyclohexanol], a potent cannabinoid that binds with similar affinity to CB1 and CB2 in vitro, produces functionally separable CB1- and CB2-mediated pharmacological effects in vivo. We evaluated antiallodynic effects, possible tolerance, and cannabimimetic effects (e.g., hypothermia, catalepsy, CB1-dependent withdrawal signs) after systemic CP55,940 treatment in a mouse model of toxic neuropathy produced by a chemotherapeutic agent, paclitaxel. The contribution of CB1 and CB2 receptors to in vivo actions of CP55,940 was evaluated using CB1 knockout (KO), CB2KO, and wild-type (WT) mice. Low-dose CP55,940 (0.3 mg/kg daily, i.p. ) suppressed paclitaxel-induced allodynia in WT and CB2KO mice, but not CB1KO mice. Low-dose CP55,940 also produced hypothermia and rimonabant-precipitated withdrawal in WT, but not CB1KO, mice. In WT mice, tolerance developed to CB1-mediated hypothermic effects of CP55,940 earlier than to antiallodynic effects. High-dose CP55,940 (10 mg/kg daily, i.p.) produced catalepsy in WT mice, which precluded determination of antiallodynic efficacy but produced sustained CB2-mediated suppression of paclitaxel-induced allodynia in CB1KO mice; these antiallodynic effects were blocked by the CB2 antagonist 6-iodopravadoline (AM630). High-dose CP55,940 did not produce hypothermia or rimonabant-precipitated withdrawal in CB1KO mice. Our results using the mixed CB1/CB2 agonist CP55,940 document that CB1 and CB2 receptor activations produce mechanistically distinct suppression of neuropathic pain. Our study highlights the therapeutic potential of targeting cannabinoid CB2 receptors to bypass unwanted central effects associated with CB1 receptor activation.

  10. CpG distribution and methylation pattern in porcine parvovirus.

    Directory of Open Access Journals (Sweden)

    Full Text Available Based on GC content and the observed/expected CpG ratio (oCpGr, we found three major groups among the members of subfamily Parvovirinae: Group I parvoviruses with low GC content and low oCpGr values, Group II with low GC content and high oCpGr values and Group III with high GC content and high oCpGr values. Porcine parvovirus belongs to Group I and it features an ascendant CpG distribution by position in its coding regions similarly to the majority of the parvoviruses. The entire PPV genome remains hypomethylated during the viral lifecycle independently from the tissue of origin. In vitro CpG methylation of the genome has a modest inhibitory effect on PPV replication. The in vitro hypermethylation disappears from the replicating PPV genome suggesting that beside the maintenance DNMT1 the de novo DNMT3a and DNMT3b DNA methyltransferases can't methylate replicating PPV DNA effectively either, despite that the PPV infection does not seem to influence the expression, translation or localization of the DNA methylases. SNP analysis revealed high mutability of the CpG sites in the PPV genome, while introduction of 29 extra CpG sites into the genome has no significant biological effects on PPV replication in vitro. These experiments raise the possibility that beyond natural selection mutational pressure may also significantly contribute to the low level of the CpG sites in the PPV genome.

    We introduce a model of a dual-core optical waveguide with opposite signs of the group-velocity-dispersion (GVD) in the two cores, and a phase-velocity mismatch between them. The coupler is embedded into an active host medium, which provides for the linear coupling of a gain-loss type between the two cores. The same system can be derived, without phenomenological assumptions, by considering the three-wave propagation in a medium with the quadratic nonlinearity, provided that the depletion of the second-harmonic pump is negligible. This linear system offers an optical realization of the charge-parity ($\\mathcal{CP}$) symmetry, while the addition of the intra-core cubic nonlinearity breaks the symmetry. By means of direct simulations and analytical approximations, it is demonstrated that the linear system generates expanding Gaussian states, while the nonlinear one gives rise to broad oscillating solitons, as well as a general family of stable stationary gap solitons.

    Supersymmetric models provide many new complex phases which lead to CP violating effects in collider experiments. As an example, CP-sensitive triple product asymmetries in neutralino production and subsequent leptonic two-body decays are studied within the Minimal Supersymmetric Standard Model. A full ILD detector simulation has been performed at a center of mass energy of 500GeV, including the relevant Standard Model background processes, a realistic beam energy spectrum, beam backgrounds and a beam polarization of 80% and -60% for the electron and positron beams, respectively. Assuming an integrated luminosity of 500fb-1 collected by the experiment and the performance of the current ILD detector, a relative measurement accuracy of 10% for the CP-sensitive asymmetry can be achieved in the chosen scenario.

    The plasticizing - antiplasticizing effect of water and glycerol contents on native corn starch samples is investigated by FT-Raman and {sup 13}C CP/MAS NMR spectroscopy. The presence of both amorphous and crystalline structural phases was evidenced in pure native corn starch and also in the samples containing plasticizers. Among the crystalline starch structures, the A- and V- types were suggested by CP/MAS NMR spectra.

    CTG repeat expansions in DMPK cause myotonic dystrophy (DM1) with a continuum of severity and ages of onset. Congenital DM1 (CDM1), the most severe form, presents distinct clinical features, large expansions, and almost exclusive maternal transmission. The correlation between CDM1 and expansion size is not absolute, suggesting contributions of other factors. We determined CpG methylation flanking the CTG repeat in 79 blood samples from 20 CDM1-affected individuals; 21, 27, and 11 individuals with DM1 but not CDM1 (henceforth non-CDM1) with maternal, paternal, and unknown inheritance; and collections of maternally and paternally derived chorionic villus samples (7 CVSs) and human embryonic stem cells (4 hESCs). All but two CDM1-affected individuals showed high levels of methylation upstream and downstream of the repeat, greater than non-CDM1 individuals (p = 7.04958 × 10(-12)). Most non-CDM1 individuals were devoid of methylation, where one in six showed downstream methylation. Only two non-CDM1 individuals showed upstream methylation, and these were maternally derived childhood onset, suggesting a continuum of methylation with age of onset. Only maternally derived hESCs and CVSs showed upstream methylation. In contrast, paternally derived samples (27 blood samples, 3 CVSs, and 2 hESCs) never showed upstream methylation. CTG tract length did not strictly correlate with CDM1 or methylation. Thus, methylation patterns flanking the CTG repeat are stronger indicators of CDM1 than repeat size. Spermatogonia with upstream methylation may not survive due to methylation-induced reduced expression of the adjacent SIX5, thereby protecting DM1-affected fathers from having CDM1-affected children. Thus, DMPK methylation may account for the maternal bias for CDM1 transmission, larger maternal CTG expansions, age of onset, and clinical continuum, and may serve as a diagnostic indicator.

  18. Silica-supported (nBuCp)2ZrCl2: Effect of catalyst active center distribution on ethylene-1-hexene copolymerization

    2013-08-12

    Metallocenes are a modern innovation in polyolefin catalysis research. Therefore, two supported metallocene catalysts-silica/MAO/(nBuCp)2ZrCl2 (Catalyst 1) and silica/nBuSnCl3/MAO/(nBuCp)2ZrCl2 (Catalyst 2), where MAO is methylaluminoxane-were synthesized, and subsequently used to prepare, without separate feeding of MAO, ethylene-1-hexene Copolymer 1 and Copolymer 2, respectively. Fouling-free copolymerization, catalyst kinetic stability and production of free-flowing polymer particles (replicating the catalyst particle size distribution) confirmed the occurrence of heterogeneous catalysis. The catalyst active center distribution was modeled by deconvoluting the measured molecular weight distribution and copolymer composition distribution. Five different active center types were predicted for each catalyst, which was corroborated by successive self-nucleation and annealing experiments, as well as by an extended X-ray absorption fine structure spectroscopy report published in the literature. Hence, metallocenes impregnated particularly on an MAO-pretreated support may be rightly envisioned to comprise an ensemble of isolated single sites that have varying coordination environments. This study shows how the active center distribution and the design of supported MAO anions affect copolymerization activity, polymerization mechanism and the resulting polymer microstructures. Catalyst 2 showed less copolymerization activity than Catalyst 1. Strong chain transfer and positive co-monomer effect-both by 1-hexene-were common. Each copolymer demonstrated vinyl, vinylidene and trans-vinylene end groups, and compositional heterogeneity. All these findings were explained, as appropriate, considering the modeled active center distribution, MAO cage structure repeat units, proposed catalyst surface chemistry, segregation effects and the literature that concerns and supports this study. While doing so, new insights were obtained. Additionally, future research, along the direction

  19. CpG Type A Induction of an Early Protective Environment in Experimental Multiple Sclerosis

    Full Text Available Experimental autoimmune encephalomyelitis (EAE is an inflammatory, demyelinating disease of the CNS that mimics human multiple sclerosis (MS, and it is thought to be driven by Th1 and Th17 myelin-reactive cells. Although adaptive immunity is clearly pivotal in the pathogenesis of EAE, with an essential role of CD4+ T cells, little is known of early, innate responses in this experimental setting. CpG-rich oligodeoxynucleotides (ODNs, typically found in microbial genomes, are potent activators of TLR9 in plasmacytoid dendritic cells (pDCs. In this study, we compared the effects of two types of CpG, namely, type A and type B, on EAE. We found that treatment with CpG type A ODN (CpG-A, known to induce high amounts of IFN-α in pDCs, significantly reduced disease severity in EAE, relative to controls (12.63±1.86 versus 23.49±1.46, resp.; p=0.001. Treatment also delayed onset of neurological deficits and reduced spinal cord demyelination, while increasing the percentage of splenic regulatory (Foxp3+ CD4+ T cells. CpG-A likewise reduced the levels of IL-17 and IFN-γ in the CNS. Mechanistic insight into those events showed that CpG-A promoted a regulatory phenotype in pDCs. Moreover, adoptive transfer of pDCs isolated from CpG-A-treated mice inhibited CNS inflammation and induced disease remission in acute-phase EAE. Our data thus identify a link between TLR9 activation by specific ligands and the induction of tolerance via innate immunity mechanisms.

    The flavor protection in composite Higgs models with partial compositeness is known to be insufficient. We explore the possibility to alleviate the tension with CP odd observables by assuming that flavor or CP are symmetries of the composite sector, broken by the coupling to Standard Model fields. One realization is that the composite sector has a flavor symmetry SU(3) or SU(3){sub U} x SU(3){sub D} which allows us to realize Minimal Flavor Violation. We show how to avoid the previously problematic tension between a flavor symmetric composite sector and electro-weak precision tests. Some of the light quarks are substantially or even fully composite with striking signals at the LHC. We discuss the constraints from recent dijet mass measurements and give an outlook on the discovery potential. We also present a different protection mechanism where we separate the generation of flavor hierarchies and the origin of CP violation. This can eliminate or safely reduce unwanted CP violating effects, realizing effectively ''Minimal CP Violation'' and is compatible with a dynamical generation of flavor at low scales. (orig.)

  1. Alternative Schemes of Predicting Lepton Mixing Parameters from Discrete Flavor and CP Symmetry

    2016-01-01

    We suggest two alternative schemes to predict lepton mixing angles as well as $CP$ violating phases from a discrete flavor symmetry group combined with $CP$ symmetry. In the first scenario, the flavor and $CP$ symmetry is broken to the residual groups of the structure $Z_2\\times CP$ in the neutrino and charged lepton sectors. The resulting lepton mixing matrix depends on two free parameters $\\theta_{\

  2. Lepton Mixing Predictions from (Generalised) CP and Discrete Flavour Symmetry

    An important class of flavour groups, that are subgroups of $U(3)$ and that predict experimentally viable lepton mixing parameters including Majorana phases, is the $\\Delta(6n^2)$ series. The most well-known member is $\\Delta(24)=S_4$. I present results of several extensive studies of lepton mixing predictions obtained in models with a $\\Delta(6n^2)$ flavour group that preserve either the full residual $Z_2\\times Z_2$ or a $Z_2$ subgroup for neutrinos and can include a generalised CP symmetry. Predictions include mixing angles and Dirac CP phase generally; and if invariance under a generalised CP symmetry is included, also Majorana phases. For this, the interplay of flavour group and generalised CP symmetry has to be studied carefully.

    First generation Leishmania vaccines consisting of whole killed parasites with or without adjuvants have reached phase 3 trial and failed to show enough efficacy mainly due to the lack of an appropriate adjuvant. In this study, the nuclease-resistant phosphorothioate CpG oligodeoxynucleotides (PS CpG) or nuclease-sensitive phosphodiester CpG ODNs (PO CpG) were used as adjuvants to enhance immunogenicity and rate of protection against leishmaniasis. Due to the susceptibility of PO CpG to nuclease degradation, an efficient liposomal delivery system was developed to protect them from degradation. 1, 2-dioleoyl-3-trimethylammonium-propane (DOTAP) as a cationic lipid was used because of its unique adjuvanticity and electrostatic interaction with negatively charged CpG ODNs. To evaluate the role of liposomal formulation in protection rate and enhanced immune response, BALB/c mice were immunized subcutaneously with liposomal soluble Leishmania antigens (SLA) co-incorporated with PO CpG (Lip-SLA-PO CpG), Lip-SLA-PS CpG, SLA+PO CpG, SLA+PS CpG, SLA or buffer. As criteria for protection, footpad swelling at the site of challenge, parasite loads, the levels of IFN-γ and IL-4, and the IgG subtypes were evaluated. The groups of mice receiving Lip-SLA-PO CpG or Lip-SLA-PS CpG showed a high protection rate compared with the control groups. In addition, there was no significant difference in immune response generation between mice immunized with PS CpG and the group receiving PO CpG when incorporated into the liposomes. The results suggested that liposomal form of PO CpG might be used instead of PS CpG in future vaccine formulations as an efficient adjuvant. Copyright © 2012 Elsevier Ltd. All rights reserved.

    We study CP asymmetries in two-body decays of top squarks into neutralinos and sleptons at the LHC. These asymmetries are used to probe the CP phases possibly present in the stop and neutralino sector of the Minimal Supersymmetric Standard Model. Taking into account bounds from experimental electric dipole moment searches, we identify areas in the mSUGRA parameter space where CP asymmetries can be sizeable and discuss the feasibility of their observation at the LHC. As a result, potentially detectable CP asymmetries in stop decays at the LHC are found, motivating further detailed experimental studies for probing SUSY CP phases.

    2011-01-01

    We study an extension of the Higgs sector of the Minimal Supersymmetric Standard Model (MSSM), considering the effects of new degrees of freedom at the TeV scale, and allowing for sources of CP violation beyond the MSSM (BMSSM). We analyze the impact of the BMSSM sources of CP violation on the Higgs collider phenomenology and on low energy flavor and CP violating observables. We identify distinct Higgs collider signatures that cannot be realized, either in the case without CP violating phases or in the CP violating MSSM, and investigate the prospects to probe them at the Tevatron and the LHC. The most striking benchmark scenario has three neutral Higgs bosons that all decay dominantly into W boson pairs and that are well within the reach of the 7 TeV LHC run. On the other hand, we also present scenarios with three Higgs bosons that have masses M_Hi > 150 GeV and decay dominantly into b bbar. Such scenarios are much more challenging to probe and can even lie completely outside the reach of the 7 TeV LHC run. W...

    Background: Tremelimumab, a fully human cytotoxic T-lymphocyte antigen 4 monoclonal antibody, and PF-3512676, a Toll-like receptor-9 agonist, are targeted immune modulators that elicit durable single-agent antitumour activity in advanced cancer. Methods: To determine the maximum tolerated dose (MTD) of these agents combined during this phase I study, patients received intravenous tremelimumab (6.0, 10.0, or 15.0 mg kg−1) every 12 weeks plus subcutaneous PF-3512676 (0.05, 0.10, or 0.15 mg kg−1) weekly. Primary end points were safety and tolerability; secondary end points included pharmacokinetics and antitumour activity. Results: Twenty-one patients with stage IV melanoma (n=17) or advanced solid tumours (n=4) were enrolled. Injection-site reactions (n=21; 100%), influenza-like illness (n=18; 86%), and diarrhoea (n=13; 62%) were the most common treatment-related adverse events (TAEs). Grade ⩾3 TAEs were reported (n=7; 33%). Dose-limiting toxicities (prespecified 6-week observation) occurred in one of the six patients in the 10 mg kg−1 tremelimumab plus 0.05 mg kg−1 PF-3512676 cohort (grade 3 hypothalamopituitary disorder) and two of the six patients in the 15 mg kg−1 tremelimumab plus 0.05 mg kg−1 PF-3512676 cohort (grade 3 diarrhoea). Consequently, 15 mg kg−1 tremelimumab plus 0.05 mg kg−1 PF-3512676 exceeded the MTD. Two melanoma patients achieved durable (⩾170 days) partial response. No human antihuman antibody responses to tremelimumab were observed. Conclusion: Weekly PF-3512676 (⩽0.15 mg kg−1) plus tremelimumab (⩽10 mg kg−1 every 12 weeks) was tolerable. PMID:23652314

    In this work we compute the CP-violating currents of the right-handed stops and higgsinos, induced by the presence of non-trivial vacuum expectation values of the Higgs fields within the context of the minimal supersymmetric extension of the Standard Model (MSSM) with explicit CP-violating phases. Using the Keldysh formalism, we perform the computation of the currents at finite temperature, in an expansion of derivatives of the Higgs fields. Contrary to previous works, we implement a resummation of the Higgs mass insertion effects to all orders in perturbation theory. While the components of the right-handed stop current j{sup {mu}}{sub t-tilde{sub R}} become proportional to the difference H{sub 2}{partial_derivative}{sup {mu}}H{sub 1}-H{sub 1}{partial_derivative}{sup {mu}}H{sub 2} (suppressed by {delta}{beta}), the higgsino currents, j{sup {mu}}{sub H-tilde{sub i}}, present contributions proportional to both H{sub 2}{partial_derivative}{sup {mu}}H{sub 1}{+-}H{sub 1}{partial_derivative}{sup {mu}}H{sub 2}. For large values of the charged Higgs mass and moderate values of tan{beta} the contribution to the source proportional to H{sub 2}{partial_derivative}{sup {mu}}H{sub 1}+H{sub 1}{partial_derivative}{sup {mu}}H{sub 2} in the diffusion equations become sizeable, although it is suppressed by the higgsino number violating interaction rate {gamma}{sub {mu}}{sup -1/2}. For small values of the wall velocity, 0.04< or approx. v{sub {omega}} < or approx. 0.1, the total contribution leads to acceptable values of the baryon asymmetry for values of the CP-violating phases phi (cursive,open) Greek{sub CP} in the range 0.04 < or approx. vertical bar sin{phi}{sub CP} vertical bar < or approx. 1. Finally, we comment on the relevance of the latest results of Higgs searches at LEP2 for the mechanism of electroweak baryogenesis within the MSSM.

However, induction of a potent T-cell immune response against tumors still remains a challenge. In this study, polyethylenimine-modified carboxyl-styrene/acrylamide (PS copolymer nanospheres were developed as a delivery system of unmethylated cytosine-phosphate-guanine (CpG oligodeoxynucleotides and transforming growth factor-beta (TGF-β receptor I inhibitors for cancer immunotherapy. TGF-β receptor I inhibitors (LY2157299, LY were encapsulated to the PS via hydrophobic interaction, while CpG oligodeoxynucleotides were loaded onto the PS through electrostatic interaction. Compared to the control group, tumor inhibition in the PS-LY/CpG group was up to 99.7% without noticeable toxicity. The tumor regression may be attributed to T-cell activation and amplification in mouse models. The results highlight the additive effect of CpG and TGF-β receptor I inhibitors co-delivered in cancer immunotherapy. Keywords: CpG, TGF-β receptor I inhibitor, Pst-AAm copolymer nanosphere, immunotherapy

    Epidemiological studies point out steady increase of the incidence of cancer disease in Poland and all over the world. Neoplasms are associated with blood coagulation disorders very frequently. The investigations concentrate on searching for the substance producing malignant cells and causing activation of blood coagulation in neoplasm disease patients. Gordon and co-workers were the first who published results of their investigation in searching for such a substance in 1975. It was isolated from the rabbit's neoplasm type V2 Ca and then characterized and named as cancer procoagulant (CP). Cancer procoagulant is responsible for blood coagulation disorders in neoplasm disease patients, incorrect metabolism of fibrin and its concentration around malignant tissues. This enzyme (in vitro) is a direct activator of the factor X, without contribution of factor VII or any other cofactors. CF differs in physical, chemical and enzymatic activity from others procoagulants. The main aim of the paper is a review of the literature for structure, chemical characteristic, occurrence and clinical relevance of the cancer procoagulant (CP) and its clinical use in current oncological diagnostics.

    We study an extension of the Standard Model (SM) in which two copies of the SM scalar $SU(2)$ doublet which do not acquire a Vacuum Expectation Value (VEV), and hence are \\textit{inert}, are added to the scalar sector. We allow for CP-violation in the \\textit{inert} sector, where the lightest \\textit{inert} state is protected from decaying to SM particles through the conservation of a $Z_2$ symmetry. The lightest neutral particle from the \\textit{inert} sector, which has a mixed CP-charge due to CP-violation, is hence a Dark Matter (DM) candidate. We discuss the new regions of DM relic density opened up by CP-violation, and compare our results to the CP-conserving limit and the Inert Doublet Model (IDM). We constrain the parameter space of the CP-violating model using recent results from the Large Hadron Collider (LHC) and DM direct and indirect detection experiments.

    A search for CP violating effects in the mixing of neutral B mesons is performed using a sample of 4.1 million hadronic Z decays collected with the ALEPH detector from 1991 to 1995. By studying time-dependent asymmetries in flavour-tagged samples of semileptonic and fully inclusive b-hadron decays, two measurements of the semileptonic asymmetry a_cp are extracted. No evidence for CP violation is observed, and the combined value a_cp = -0.013 +- 0.026 is obtained.

    A preliminary determination of the Dirac phase in the PMNS matrix is δ{sub PMNS}≈-(π/2). A rather accurately determined Jarlskog invariant J in the CKM matrix is close to the maximum. Since the phases in the CKM and PMNS matrices will be accurately determined in the future, it is an interesting problem to relate these two phases. This can be achieved in a families-unified grand unification if the weak CP violation is introduced spontaneously à la Froggatt and Nielsen at a high energy scale, where only one meaningful Dirac CP phase appears.

  18. CP asymmetries in semiinclusive B0 decays

    Energy Technology Data Exchange (ETDEWEB)

    Dunietz, Isard

    1999-02-01

    It was recently pointed out that inclusive B^0(t) decays could show CP violation. The totally inclusive asymmetry is expected to be tiny [O(10^{-3})] because of large cancellations among the asymmetries in the charmless, single charm and double charm final states. Enriching particular final state configurations could significantly increase the CP-asymmetry and observability. Such studies can extract fundamental CKM (Cabibbo-Kobayashi-Maskawa) parameters, and (perhaps) even Delta m(B_s). A superb vertex detector could see CP violation with 10^5 (10^6) flavor-tagged B_s (B_d) mesons within the CKM model. Because the effects could be significantly larger due to new physics, they should be searched for in existing or soon available data samples.

  19. Flavor-diagonal CP violation

    2012-09-01

    The focus of this brief review is on new physics (NP) sources of CP violation, especially related to the flavor-diagonal phenomena of electric dipole moments (EDMs) of elementary particles and atoms. Using weak scale supersymmetry as an example, we illustrate various aspects of the "new physics CP-problem". We also explore the interplay between flavor-changing and flavor-diagonal CP violation in the context of the recent hints from the Tevatron for new sources of CP violation in the B-meson systems.

  20. On the determination of the CP of the Higgs boson

    Energy Technology Data Exchange (ETDEWEB)

    Skjold, A.

    1995-12-31

    While the Higgs particle of the Standard Models is a Cp-even scalar particle, extended models may contain Higgs particles that are odd under CP, and also models invoking Higgs-like particles which are not eigenstates of CP may be considered. In the context of Higgs production via the Bjorken process and Higgs decay to tour fermions distributions that are sensitive to the CP parity are discussed. The author also discuss observables which may demonstrate presence of CP violation and identify a phase shift {delta} which is a measure of the strength of CP violation in the Higgs-vector-vector coupling, and which can be measured directly in the relevant distribution. In the case of Higgs production via the Bjorken process at a future e{sup +}e{sup -}collider, Monte Carlo data on the expected efficiency is presented, and it is concluded that it is relatively easy to determine whether the produced particle is even or odd under CP. However, observation of any CP violation would require a very large amount of data. It is argued that the analogous prospects at LEP2 or at a future hadron collider like the LHC seem to be less promising. 63 refs.

  1. A diabatic definition of geometric phase effects

    Izmaylov, Artur F; Joubert-Doriol, Loic

    2016-01-01

    Electronic wave-functions in the adiabatic representation acquire nontrivial geometric phases (GPs) when corresponding potential energy surfaces undergo conical intersection (CI). To define dynamical effects arising from the GP presence in the nuclear quantum dynamics we explore a removal of the GP via modification of the underlying diabatic representation. Using an absolute value function of diabatic couplings we remove the GP while preserving adiabatic potential energy surfaces and CI. We assess GP effects in dynamics of a two-dimensional linear vibronic coupling model both for ground and excited state dynamics. Results are compared with those obtained with a conventional removal of the GP by ignoring double-valued boundary conditions of the real electronic wave-functions. Interestingly, GP effects appear similar in two approaches only for the low energy dynamics, while the new approach does not have substantial GP effects in the ultra-fast excited state dynamics.

    Direct CP violation in the hadronic decays B{yields}{pi}{sup +}{pi}{sup -}{pi}{sup 0} is investigated near the peak of the {rho}{sup 0}, taking into account the effect of {rho}- {omega} mixing. The branching ratios for the processes B{sup {+-}}{sup ,0} {yields}{rho}{sup {+-}}{sup ,0}{pi}{sup {+-}}{sup ,0} and B{sup -}{yields}{omega}{pi}{sup -} are calculated as well. We find that the CP violating asymmetry is strongly dependent on the CKM matrix elements. For a fixed N{sub c}{sup eff}, the CP violating asymmetry, a{sub CP}, has a maximum of order -40% to - 70% for B{yields}{rho}{sup 0}({omega}) {pi}{sup 0} when the invariant mass of the {pi}{sup +}{pi}{sup -} pair is in the vicinity of the {omega} resonance. The sensitivity of the asymmetry to N{sub c}{sup eff} is small in that case. Moreover, we find that in the range of N{sub c}{sup eff} which is allowed by the most recent experimental branching ratios from the BABAR, BELLE and CLEO Collaborations, the sign of sin {delta} is always positive. Thus, a measurement of direct CP violation in the decays B{yields}{pi}{sup +}{pi}{sup -}{pi}{sup 0} would remove the mod ({pi}) ambiguity in the determination of the CP violating phase angle {alpha}.

    Beauty baryons are being observed in large number in the LHCb detector. The rich kinematics of their multibody decays are therefore becoming accessible and provide us with new opportunities to search for CP violation. We analyse the angular distributions of some three- and four-body decays of spin-$1/2$ baryons using the Jacob-Wick helicity formalism. The asymmetries that provide access to small differences of CP-odd phases between decay amplitudes of identical CP-even phases are notably discussed. The understanding gained on processes featuring specific resonant intermediate states allows us to establish which asymmetries are relevant for what purpose. It is for instance shown that some CP-odd angular asymmetries measured by the LHCb collaboration in the $\\Lambda_b \\to \\Lambda\\,\\varphi \\to p\\,\\pi\\, K^+ K^-$ decay are expected to vanish identically.

    Higgs boson production in association with two tagging jets will be mediated by electroweak vector boson fusion and by gluon fusion. For the gluon fusion process, analysis of the azimuthal angle correlations of the two jets provides for a direct measurement of the CP-nature of the $Htt$ Yukawa coupling which is responsible for the effective $Hgg$ vertex.

    The potential benefit of using unmethylated CpG oligoribodeoxynucleotides (ODN) as an adjuvant in a therapeutic simian immunodeficiency virus (SIV) vaccine consisting of AT2-inactivated SIVmac239 was evaluated in SIV-infected rhesus macaques receiving antiretroviral therapy (ART). We hypothesized that using CpG ODN as an adjuvant in therapeutic vaccination would enhance SIV-specific immune responses and suppress SIV replication after ART was stopped. To test our hypothesis, we immunized chronically SIV-infected rhesus macaques receiving ART with one of the following therapeutic vaccines: (i) AT2-inactivated SIVmac239, (ii) CpG10103 plus AT2-inactivated SIVmac239, (iii) CpG10103, and (iv) saline. While immunization with CpG plus AT2-SIVmac239 significantly increased SIV-specific immunoglobulin G (IgG) antibody titers, the mean plasma viral RNA (vRNA) level in these animals after ART did not differ from those of saline-treated animals. The AT2-inactivated SIVmac239-immunized animal group had a significantly higher mean SIV-specific gamma interferon T-cell response after three immunizations and lower plasma vRNA levels for 6 weeks after ART was withdrawn compared to the saline-treated animal group. Compared to the saline control group, the animal group treated with CpG alone had a significantly higher mean SIV-specific lymphocyte proliferation index and a higher rate of plasma vRNA rebound after ART. These results demonstrate that while the use of CpG as an adjuvant enhances SIV-specific antibody responses, this does not improve the control of SIV replication after ART is stopped. The lack of benefit may be related to the high levels of SIV-specific lymphocyte proliferation in the CpG adjuvant group.

    The strengthening effect of a Zn alloy reinforced by SiC particulate was examined. Based on the results of SEM in-situ fracture observation and stress field analysis by finite element method, it is believed that the reinforcing effect of this composite is due to the combination of strain and stress hardening in the matrix.

    We review the present state of knowledge of the mixing of quark flavors under weak interactions and the associated explanation of CP violation inherent in the single nontrivial phase present in the three-generation mixing matrix. In this context we present the phenomenological basis for the increasing possibility that large CP violation asymmetries can be experimentally observed in the B meson system. 39 refs., 11 figs.,

    To investigate the effects of a new derivative of bisphosphonates, [2-(6-aminopurine-9-yl)-1-hydroxy-phosphine acyl ethyl] phosphonic acid (CP), on human gastric cancer. Human gastric cancer cell lines (SGC-7901, BGC-823, MKN-45, and MKN-28) and human colon carcinoma cell lines (LoVo and HT-29) were tested. Cell growth was determined using the MTT assay. Flow cytometry, Western blot, caspase activity assay and siRNA transfection were used to examine the mechanisms of anticancer action. Female BALB/c nude mice were implanted with SGC-7901 cells. From d6 after inoculation, the animals were injected with CP (200 μg/kg, ip) or vehicle daily for 24 d. CP suppressed the growth of the 6 human cancer cell lines with similar IC50 values (3239 μmol/L). In SGC-7901 cells, CP arrested cell cycle progression at the G2/M phase. The compound activated caspase-9, increased the expression of pro-apoptotic proteins Bax and Bad, decreased the expression of anti-apoptotic protein Bcl-2. Furthermore, the compound selectively activated ERK1/2 without affecting JNK and p38 in SGC-7901 cells. Treatment of SGC-7901 cells with the specific ERK1/2 inhibitor PD98059 or ERK1/2 siRNA hampered CP-mediated apoptosis. In the human gastric cancer xenograft nude mouse model, chronic administration of CP significantly retarded the tumor growth. CP is a broad-spectrum inhibitor of human carcinoma cells in vitro, and it also exerts significant inhibition on gastric cancer cell growth in vivo. CP induces human gastric cancer apoptosis via activation of the ERK1/2 signaling pathway.

    We discuss flavour dependent leptogenesis in the framework of lepton flavour models based on discrete flavour and CP symmetries applied to the type-I seesaw model. Working in the flavour basis, we analyse the case of two general residual CP symmetries in the neutrino sector, which corresponds to all possible semi-direct models based on a preserved Z{sub 2} in the neutrino sector, together with a CP symmetry, which constrains the PMNS matrix up to a single free parameter which may be fixed by the reactor angle. We systematically study and classify this case for all possible residual CP symmetries, and show that the R-matrix is tightly constrained up to a single free parameter, with only certain forms being consistent with successful leptogenesis, leading to possible connections between leptogenesis and PMNS parameters. The formalism is completely general in the sense that the two residual CP symmetries could result from any high energy discrete flavour theory which respects any CP symmetry. As a simple example, we apply the formalism to a high energy S{sub 4} flavour symmetry with a generalized CP symmetry, broken to two residual CP symmetries in the neutrino sector, recovering familiar results for PMNS predictions, together with new results for flavour dependent leptogenesis.

    Insulin resistance is a major contributor to macro- and microvascular complications, particularly in the presence of the metabolic syndrome, and is also associated with polycystic ovary syndrome. Impaired nitric oxide metabolism and endothelial function are important components of the vascular disease. Increasing the bioavailability of arginine, the precursor of nitric oxide, thus potentially offers protection against end-stage disease. We have recently demonstrated that dietary supplementation with a novel silicate inositol arginine complex reduces vasculopathy and glomerular sclerosis in the insulin-resistant JCR:LA-cp rat. The objective of this study was to address the absorption of, and the underlying metabolic alterations caused by, the arginine silicate inositol complex and arginine HCl (as a reference agent) in obese insulin-resistant male and female JCR:LA-cp rats. Male and female rats were treated with the preparations at 1.0 mg/(kg d) (expressed as arginine HCl) from 8 to 12 and 12 to 18 weeks of age, respectively. Obese female, but not male, rats treated with the arginine silicate inositol complex showed a reduced rate of weight gain without concomitant reduction in food intake. Plasma silicon levels were raised very significantly in arginine silicate-treated rats, consistent with significant absorption of the complex. In male rats, arginine levels were elevated by treatment with arginine silicate only; and female rats responded to both preparations. Plasma concentrations of oxides of nitrogen in rats treated with the silicate complex showed a dimorphism, decreasing in male and increasing in female rats. Fasting insulin levels were elevated in male rats treated with the arginine silicate complex, whereas fasting and postprandial insulin levels were decreased in female rats. Furthermore, female, but not male, rats treated with either of the arginine preparations showed significant reductions in cholesterol, triglyceride, and phospholipid concentrations

    Two catalysts, denoted as catalyst 1 [silica/MAO/(nBuCp) 2ZrCl2] and catalyst 2 [silica/nBuSnCl 3/MAO/(nBuCp)2ZrCl2] were synthesized and subsequently used to prepare, without separate feeding of methylaluminoxane (MAO), ethylene homopolymer 1 and homopolymer 2, respectively, and ethylene-1-hexene copolymer 1 and copolymer 2, respectively. Gel permeation chromatography (GPC), Crystaf, differential scanning calorimetry (DSC) [conventional and successive self-nucleation and annealing (SSA)], and 13C nuclear magnetic resonance (NMR) polymer characterization results were used, as appropriate, to model the catalyst active-center distribution, ethylene sequence (equilibrium crystal) distribution, and lamellar thickness distribution (both continuous and discrete). Five different types of active centers were predicted in each catalyst, as corroborated by the SSA experiments and complemented by an extended X-ray absorption fine structure (EXAFS) report published in the literature. 13C NMR spectroscopy also supported this active-center multiplicity. Models combined with experiments effectively illustrated how and why the active-center distribution and the variance in the design of the supported MAO anion, having different electronic and steric effects and coordination environments, influence the concerned copolymerization mechanism and polymer properties, including inter- and intrachain compositional heterogeneity and thermal behaviors. Copolymerization occurred according to the first-order Markovian terminal model, producing fairly random copolymers with minor skewedness toward blocky character. For each copolymer, the theoretical most probable ethylene sequences, nE MPDSC-GT and n E MPNMR-Flory, as well as the weight-average lamellar thicknesses, Lwav DSC-GT and Lwav SSA DSC, were found to be comparable. To the best of our knowledge, such a match has not previously been reported. The percentage crystallinities of the homo- and copolymers increased linearly as a function of

    In Alonso et al., JHEP 12 (2014) 034, the CP-even sector of the effective chiral Lagrangian for a generic composite Higgs model with a symmetric coset has been constructed, up to four momenta. In this paper, the CP-odd couplings are studied within the same context. If only the Standard Model bosonic sources of custodial symmetry breaking are considered, then at most six independent operators form a basis. One of them is the weak- θ term linked to non-perturbative sources of CP violation, while the others describe CP-odd perturbative couplings between the Standard Model gauge bosons and an Higgs-like scalar belonging to the Goldstone boson sector. The procedure is then applied to three distinct exemplifying frameworks: the original SU(5)/SO(5) Georgi-Kaplan model, the minimal custodial-preserving SO(5)/SO(4) model and the minimal SU(3)/(SU(2) × U(1)) model, which intrinsically breaks custodial symmetry. Moreover, the projection of the high-energy electroweak effective theory to the low-energy chiral effective Lagrangian for a dynamical Higgs is performed, uncovering strong relations between the operator coefficients and pinpointing the differences with the elementary Higgs scenario.

    We point out that there is a unique parametrization of quark flavor mixing in which every angle is close to the Cabibbo angle \\theta_C \\simeq 13^\\circ with the CP-violating phase \\phi_q around 1^\\circ, implying that they might all be related to the strong hierarchy among quark masses. Applying the same parametrization to lepton flavor mixing, we find that all three mixing angles are comparably large (around \\pi/4) and the Dirac CP-violating phase \\phi_l is also minimal as compared with its values in the other eight possible parametrizations. In this spirit, we propose a simple neutrino mixing ansatz which is equivalent to the tri-bimaximal flavor mixing pattern in the \\phi_l \\to 0 limit and predicts \\sin\\theta_13 = 1/\\sqrt{2} \\sin (\\phi_l/2) for reactor antineutrino oscillations. Hence the Jarlskog invariant of leptonic CP violation J_l = (\\sin\\phi_l)/12 can reach a few percent if \\theta_13 lies in the range 7^\\circ \\leq \\theta_13 \\leq 10^\\circ.

    We point out that there is a unique parametrization of quark flavor mixing in which every angle is close to the Cabibbo angle θC≃13° with the CP-violating phase ϕq around 1°, implying that they might all be related to the strong hierarchy among quark masses. Applying the same parametrization to lepton flavor mixing, we find that all three mixing angles are comparably large (around π/4) and the Dirac CP-violating phase ϕl is also minimal as compared with its values in the other eight possible parametrizations. In this spirit, we propose a simple neutrino mixing ansatz which is equivalent to the tri-bimaximal flavor mixing pattern in the ϕl→0 limit and predicts sin θ13=1/√{2}sin(ϕl/2) for reactor antineutrino oscillations. Hence the Jarlskog invariant of leptonic CP violation Jl=(sin ϕl)/12 can reach a few percent if θ13 lies in the range 7°⩽θ13⩽10°.

    We have isolated PF1092A, B, and C, novel nonsteroidal progesterone ligands with preferential affinity for the progesterone receptor, from fermentation broth of a fungus [Tabata Y, Miike N, Hatsu M, Kurata Y, Yaguchi T, Someya A, Miyadoh S, Hoshiko S, Tsuruoka T, and Omoto S (1997) J Antibiot 50:304-308; Tabata Y, Hatsu M, Kurata Y, Miyajima K, Tani M, Sasaki T, Kodama Y, Tsuruoka T, and Omoto S (1997) J Antibiot 50:309-313]. The original skeleton of PF1092, tetrahydronaphthofuranone, was modified synthetically to produce a new skeleton, tetrahydrobenzindrone, and in the present study, biological activities of two derivatives, CP8816 [(4aR,5R,6R,7R)-6-(N,N-dimethylaminocarbonyl)oxy-7-methoxy-4a,5,6,7-tetrahydro-1,3,4a,5-tetramethylbenz[f]indol-2(4H)-one] and CP8863 [(4aR,5R,6R,7R)-7-hydroxy-6-(N-methylcarbamoyl)oxy-4a,5,6,7-tetrahydro-1,3,4a,5-tetramethylbenz[f]indol-2(4H)-one], were investigated. Both CP8816 and CP8863 demonstrated selective binding to progesterone receptor and partial agonistic activity in a progesterone-dependent endogenous alkaline phosphatase expression assay. In the Clauberg-McPhail test, progestational activity of CP8816 (0.1 mg/kg s.c. or 10 mg/kg p.o.) was comparable to that of progesterone (0.15 mg/kg s.c.), and oral administration of CP8863 at more than 1.0 mg/kg also exerted similar effects. Anti-estrogenic (antiuterotropic) activity was confirmed on daily oral application of more than 0.1 mg/kg CP8863 for 3 days by inhibition of estrogen-dependent uterine wet weight gain in ovariectomized rats. CP8816 also exerted antiuterotropic activity at doses of 10 mg/kg (s.c.) and 100 mg/kg (p.o.). These results indicate that our nonsteroidal progesterone ligands have affinity for the progesterone receptor with partial progestational activity in vitro and clear progestational effects in vivo. Thus, these progesterone receptor modulator profiles suggest that CP8863 and CP8816 are good candidate compounds for treatment of hormone

  18. Implications of CP violating 2HDM in B physics

    Joshipura, Anjan S

    2010-01-01

    The charged fermion mass matrices are invariant under $U(1)^3$ symmetry linked to the fermion number transformation. Under the condition that the definition of this symmetry in arbitrary weak basis does not depend upon Higgs parameters such as ratio of vacuum expectation values, a class of two Higgs doublet models (2HDM) can be identified in which tree level flavor changing neutral currents normally present in 2HDM are absent. However unlike the type I or type II Higgs doublet models, the charged Higgs couplings in these models contain additional flavor dependent CP violating phases. These phases can account for the recent hints of the beyond standard model CP violation in the $B_d$ and $B_s$ mixing. In particular, there is a range of parameters in which new phases do not contribute to the $K$ meson CP violation but give identical new physics phases in the $B_d$ and $B_s$ meson mixing.

    2016-01-01

    Outer automorphisms of symmetries ("symmetries of symmetries") in relativistic quantum field theories are studied, including charge conjugation (C), space-reflection (P) , and time-reversal (T) transformations. The group theory of outer automorphisms is pedagogically introduced and it is shown that CP transformations are special outer automorphisms of the global, local, and space-time symmetries of a theory. It is shown that certain discrete groups allow for a group theoretical prediction of parameter independent CP violating complex phases with fixed geometrical values. The remainder of this thesis pioneers the study of outer automorphisms which are not related to C, P, or T. It is shown how outer automorphisms, in general, relate symmetry invariants and, in theories with spontaneous symmetry breaking, imply relations between different vacuum expectation values. Thereby, outer automorphisms can give rise to emergent symmetries. An example model with a discrete symmetry and three copies of the Standard Model ...

  20. Lattice matrix elements and CP violation in and physics: Status and outlook

    Indian Academy of Sciences (India)

    Amarjit Soni

    2004-02-01

    Status of lattice calculations of hadron matrix elements along with CP violation in $B$ and in $K$ systems is reviewed. Lattice has provided useful input which, in conjunction with experimental data, leads to the conclusion that CP-odd phase in the CKM matrix plays the dominant role in the observed asymmetry in $B→ K_{s}$. It is now quite likely that any beyond the SM, CP-odd, phase will cause only small deviations in $B$-physics. Search for the effects of the new phase(s) will consequently require very large data samples as well as very precise theoretical predictions. Clean determination of all the angles of the unitarity triangle therefore becomes essential. In this regard $B→ KD^{0}$ processes play a unique role. Regarding $K$-decays, remarkable progress made by theory with regard to maintenance of chiral symmetry on the lattice is briefly discussed. First application already provide quantitative information on $B_{K}$ and the $ I=1/2$ rule. In the lattice calculation, the enhancement in Re $A_{0}$ appears to arise solely from tree operators, esp. $Q_{2}$; penguin contribution to Re $A_{0}$ appears to be very small. However, improved calculations are necessary for $'/$ as the contributions of QCD penguins and electroweak penguins largely seem to cancel. There are good reasons, though, to believe that these cancellations will not survive improvements that are now underway. Importance of determining the unitarity triangle purely from $K$-decays is also emphasized.
