    1987-01-01

    The knock-out reaction A(anti p,p)X has been used to search for narrow anti p-nucleus states. The experiment was performed using the 600 MeV/c antiproton beam at LEAR and the high-resolution and large-acceptance magnetic spectrometer SPES II. The A-dependence of the annihilation-induced proton spectra has been studied on 2 H, 6 Li, 12 C, 63 Cu, 208 Pb and 209 Bi. The quasi-free elastic anti pp scattering observed in the lighter targets, and the comparison with the free anti pp scattering, also observed in this experiment, determine an effective proton number N eff for 1s- and 1p-shell protons. No evidence for narrow bound or resonant anti p-nucleus states could be found. Upper limits for their production are one order of magnitude lower than certain theoretical predictions, but consistent with the properties of the anti p-nucleus interaction, as established from recent elastic and inelastic scattering as well as from studies of antiprotonic atoms.

  2. Two searches for narrow anti pp states in πp interactions

    International Nuclear Information System (INIS)

    Carroll, A.S.

    1980-01-01

    Both experiments searched for evidence of narrow anti pp states produced predominately by baryon exchange and were sufficiently sensitive to test decisively for the presence of the 2020 and 2204 MeV states reported by the CERN Omega experiment of P. Benkheiri, et al. The techniques employed in the two experiments were sufficiently different such that any systematic biases were extremely unlikely to have occurred in both experiments

    1985-01-01

    We have studied (anti p,p) reactions on 12 C, 63 Cu, and 209 Bi to search for possible nuclear states formed by antiprotons and nuclei. The experiments used the 180 MeV antiproton beam from LEAR, and the high-resolution magnetic spectrometer, SPES II, to detect the outgoing protons. No evidence of antiproton-nucleus states was found. The gross features of the proton spectra are reasonably well described by intranuclear cascade model calculations, which consider proton emission following antiproton annihilations in the target nucleus.

  4. Partial wave analysis of anti ppanti ΛΛ

    International Nuclear Information System (INIS)

    Bugg, D.V.

    2004-01-01

    A partial wave analysis of PS185 data for anti ppanti ΛΛ is presented. A 3 S 1 cusp is identified in the inverse process anti ΛΛ→ anti p p at threshold, using detailed balance to deduce cross sections from anti ppanti ΛΛ. Partial wave amplitudes for anti pp 3 P 0 , 3 F 3 , 3 D 3 and 3 G 3 exhibit a behaviour very similar to resonances observed in Crystal Barrel data. With this identification, the anti ppanti ΛΛ data then provide evidence for a new I=0, J PC =1 - resonance with mass M = 2290 ±20 MeV, Γ= 275 ±35 MeV, coupling to both 3 S 1 and 3 D 1 . (orig.)

    1992-01-01

    We report on a study of the χ 1 ( 3 P 1 ) and χ 2 ( 3 P 2 ) states of charmonium formed in antiproton-proton annihilations. An energy scan through the resonances, performed with a very narrow momentum-band beam of antiprotons intersecting a hydrogen jet target, enables us to perform very precise measurements of the mass and the total width of the two resonances. From a sample of 513 χ 1 and 585 χ 2 events we find M χ1 =(3510.53±0.13) MeV/c 2 , M χ2 =(3556.15±0.14) MeV/c 2 , Γ χ1 =(0.88±0.14) MeV and Γ χ2 =(1.98±0.18) MeV. From our measurement of the quantity Γ(R→anti pp)xBR(R→J/ψγ)xBR(J/ψ→e + e - ), using known branching ratios, we obtain Γ(χ 1 →anti pp)=(69±13) eV and Γ(χ 2 →anti pp)=(180±31) eV. (orig.)

    ISAJET is a Monte Carlo program which simulates pp and anti pp interactions at high energy. It is based on perturbative QCD cross sections, leading order QCD radiative corrections for initial and final state partons, and phenomenological models for jet and beam jet fragmentation.

  7. Some Aspects of the OZI-Rule Violation in the Reaction Anti pp → φπ0

    International Nuclear Information System (INIS)

    Buzatu, D.; Lev, F.M.

    1994-01-01

    We consider the problem whether the violation of the OZI-rule in the reaction anti pp → φπ 0 can be explained as the effect of rescattering in the processes anti pp → (K*anti K + anti K*K) → K anti Kπ 0 → φπ 0 and (or) anti pp → ρ + ρ - → (ρ + π - + ρ - π + )π 0 → φπ 0 . If this effect is important then it is possible to give theoretical predictions concerning the energy dependence of the quantity BR(anti pp → φπ 0 )/BR(anti pp → K*anti K) and the value of this quantity in the annihilation at rest from the P state. At the same time the analogous effect in the reaction anti pp → f 2 'π 0 is negligible. 14 refs., 7 figs

    Antiproton-proton and proton-proton elastic scattering are studied simultaneously over the energy range ..sqrt..anti s approx.= (10/1000) GeV in a nucleon valence core model proposed earlier. The scattering is described as primarily due to two processes: diffraction and hard scattering. The latter originates from the scattering of a nucleon core off another core. Destructive interference between the two processes produces dips in anti pp and pp differential cross-sections. As energy increases beyond the ISR range (..sqrt..anti s = (23/62) GeV), the dips get filled up, and eventually transform into shoulders or breaks at collider energies. Differences between anti pp and pp differential cross-sections persist even at collider energies. Comparison with ISR data shows that the model provides a quantitative description of pp elastic scattering in this energy range. Predictions of anti pp and pp differential cross-sections at future collider energies ..sqrt..s = 800 and 2000 GeV are given. In order to distinguish between competing models, need for measuring the anti pp differential cross-section at the ISR and SPS collider in the vertical stroketvertical stroke-range (0.5/2.0) (GeV)/sup 2/ is stressed.

    Jung, M.

    1978-01-01

    A review concerning specific properties of anti-pp collisions has been done through the summary of several theoretical and experimental papers. Some new experimental measurements are suggested towards the analysis of different already known hadronic processes

  12. Structures in anti pp → π π

    International Nuclear Information System (INIS)

    Martin, B.R.; Morgan, D.

    1980-03-01

    A Barrelet-zero analysis is presented of data on anti pp → π π in the momentum range 1 to 2 GeV/c. With π - π + data alone, the scope for ambiguity is very large but the addition of π 0 π 0 information enables the number of solutions to be reduced to just a few. Although the alternative solutions differ considerably, they have significant common features, in particular, with plausible extra assumptions, all solutions appear to be dominated by resonance in all spin states from J = 1 to 5

  13. Comparison of short-range rapidity correlations in anti pp and pp interactions at √S = 53 GeV

    Breakstone, A.; Crawley, H.B.; Firestone, A.; Gorbics, M.; Lamsa, J.W.; Meyer, W.T.

    1982-01-01

    Measurements are presented of two-particle rapidity correlations in anti pp and pp at √S = 53 GeV. The data were recorded at the CERN-ISR using the Split Field Magnet spectrometer with a minimum bias trigger. Short range correlations in normal inelastic events with measured charged multiplicities nsub(ch) >= 4 are observed for pairs of charged particles in all charge combinations. Within the experimental errors no differences are observed between the analogous correlations in pp and anti pp interactions. (orig.)

  14. The Fermilab anti pp collider

    International Nuclear Information System (INIS)

    Harrison, M.

    1984-01-01

    The goal of the Tevatron I project is to achieve anti pp collisions in the centre-of-mass energy range up to 2 TeV with a luminosity of at least 10 30 cm -2 sec -1 . The project involves adapting the Tevatron to function as a storage ring and modifying the lattice to provide low-beta interaction points; changes to the Main Ring to allow anti p transfers and the installation of experimental equipment; and the construction of a anti p source. Major experimental areas will be located in the socalled BO and DO straight sections together with smaller, more specialized experiments in several of the other interacting regions. (orig./HSI)

  15. A study of the reaction anti pp→anti ppπ+π- at a beam momentum of 7.23 GeV/c

    International Nuclear Information System (INIS)

    Apeldoorn, G. van.

    1980-01-01

    The experiment and the measurement system are described. The determination of the momentum of the incident antiproton and the automatic decision system based on the measured ionization density are discussed in somewhat more detail, because the author has been especially involved in these aspects of the experiment. The cross section for the anti ppπ + π - final state is determined from the experimental data, the validity of the symmetry with respect to charge conjugation is tested and the separation of the sample in two classes is discussed, one mainly produced by one pion exchange and the other by diffraction dissociation. The predictions of the OPE-model are compared with the experimental data for the reaction anti pp → Δ(1236)anti Δ(1236). (Auth.)

  16. High energy pp and anti-pp elastic scattering in nucleon valence core model

    International Nuclear Information System (INIS)

    Islam, M.M.; Fearnley, T.

    1986-01-01

    Connection between the valence core model and the effective QCD models of nucleon structure is pointed out. Also, implication of recent anti-pp differential cross section measurements at 53 GeV on our previous calculations is discussed

  17. Using anti pp annihilation to find exotic mesons

    International Nuclear Information System (INIS)

    Sharpe, S.R.

    1987-10-01

    Present data suggests that a number of mesons have been found which cannot be accommodated in standard anti qq multiplets. Theory suggests that such exotic mesons should exist in the spectrum of Quantum Chromodynamics, but provides little guide to their properties. It is argued that a high luminosity, low energy anti pp machine would be a powerful tool with which to search for such exotics

  18. Search for substructure in anti pp total cross section in the 2200 MeV mass region

    International Nuclear Information System (INIS)

    Peaslee, D.C.; DeMarzo, C.; Guerriero, L.

    1975-01-01

    The anti pp total cross section is measured in an apparatus with a small target and high resolution beam in order to supplement previous work by looking for narrow structure that might be hidden in broad-mass bins. One could set limits on the partial widths of bosons coupling to the anti pp system. The product of an unknown production cross section and a partial width was determined. From the data the existence of resolution-sized structure above the smooth fit with the product of cross section and width greater than 7 MeV mb. It can be shown that a Breit--Wigner resonance of spin J coupled to the anti pp system in this region must have partial width GAMMA/sub anti pp/ less than 1.8/(2J + 1) MeV. Also it is found that the broad enhancement observed in the anti pp total cross section persists without modification in an observation with mass resolution six times that of previous work

    Boos, E.G.; Samojlov, V.V.; Tashimov, M.A.

    1977-01-01

    Forward-backward multiplicity correlations in anti pp -interactions at 22.4 GeV/c and multiplicities in a simple icle multiplicity distribution is divided into even and odd components, the probability of producting an odd state is found to be higher than that of producing an even state, which may be interpreted to be due to diffraction forward-backward and to everall multiplicities is discussed

    The anti pp elastic differential cross section at 30 GeV/c incident momentum has been measured in a two-arm spectrometer experiment (WA7) at the CERN SPS. The vertical stroketvertical stroke-range covered extends from 0.5 to 5.8 (GeV/c) 2 . A pronounced dip-bump structure is observed, with a sharp minimum around vertical stroketvertical strokeapprox.=1.7 (GeV/c) 2 . The results are compared with existing anti pp data at lower energies and with our earlier anti pp data at 50 GeV/c. A number of model predictions are discussed. We also compare the anti pp 30 GeV/c differential cross section with that of pp at the same momentum. Finally, the energy dependence of the anti pp fixed-vertical stroketvertical stroke differential cross section in the incident momentum range 3.6 to 50 GeV/c is presented. (orig.)

    Reimer, P.

    Data are presented on azimuthal two particle correlations and the effect is estimated of resonance production on these correlations in anti pp interactions at 22.4 GeV/c. Attention is paid to correlations between two charged pions produced in the process anti p+p→ two charged pions + anything. The dependence is described of the azimuthal asymmetry parameter on rapidity difference. (Z.J.)

    Protein phosphatase 6 (PP6) is a ubiquitous Ser/Thr phosphatase involved in an array of cellular processes. To assess the potential of PP6 as a therapeutic target in liver disorders, we attenuated expression of the PP6 catalytic subunit in HepG2 cells using lentiviral-transduced shRNA. Two PP6 knock-down (PP6KD) cell lines (90% reduction of PP6-C protein content) were studied in depth. Both proliferated at a rate similar to control cells. However, flow cytometry indicated G2/M cell cycle arrest that was accounted for by a shift of the cells from a diploid to tetraploid state. PP6KD cells did not show an increase in apoptosis, nor did they exhibit reduced viability in the presence of bleomycin or taxol. Gene expression analysis by microarray showed attenuated anti-inflammatory signaling. Genes associated with DNA replication were downregulated. Mass spectrometry-based phosphoproteomic analysis yielded 80 phosphopeptides representing 56 proteins that were significantly affected by a stable reduction in PP6-C. Proteins involved in DNA replication, DNA damage repair and pre-mRNA splicing were overrepresented among these. PP6KD cells showed intact mTOR signaling. Our studies demonstrated involvement of PP6 in a diverse set of biological pathways and an adaptive response that may limit the effectiveness of targeting PP6 in liver disorders. - Highlights: • Lentiviral-transduced shRNA was used to generate a stable knockdown of PP6 in HepG2 cells. • Cells adapted to reduced PP6; cell proliferation was unaffected, and cell survival was normal. • However, PP6 knockdown was associated with a transition to a tetraploid state. • Genomic profiling showed downregulated anti-inflammatory signaling and DNA replication. • Phosphoproteomic profiling showed changes in proteins associated with DNA replication and repair.

    Maher, C.J.

    1986-06-01

    Measurements of differential and integrated cross sections as well as final state polarizations for the anti p p → anti Λ Λ reaction are presented. The reaction was studied at two incident antiproton momenta (1476.5 MeV/c and 1507.5 MeV/c) corresponding to total center of mass energies of 15.5 MeV and 26.4 MeV above the reaction threshold. The trajectories of charged decay products of the anti Λ and Λ were observed in a multiwire proportional chamber and in two sets of drift chambers. The data were analyzed with a computer program which reconstructed anti p p → anti Λ Λ → anti p π + pπ - events and performed kinematic fitting. The results are compared to several recent meson exchange calculations, and a one-gluon exchange calculation. The experiment was performed at the Low Energy Antiproton Ring (LEAR) at CERN. The data presented represent the first results of the PS185 collaboration's study of the threshold production of hyperon-antihyperon states

    1983-04-01

    We will present the results of two recently published (1983) papers by M.M. Block and R.N. Cahn, which analyze for anti pp and pp elastic scattering the rho values (ratios of the real to the imaginary parts of the forward nuclear scattering amplitudes), the total (hadronic) cross sections sigma, and the b values, the nuclear slope parameters. The predictions of the analyses, from √ s bar > 5 GeV, is compared with the recently measured values of sigma and b at the SPS Collider. The analysis has also been redone to include new ISR data available from R211 at √ s bar = 62.5 GeV, in order to estimate odderon contributions, i.e., contributions from odd amplitudes with unconventional (non-Reggeon) energy dependence. Limits of approx. 1% are placed on these amplitudes. Our analysis has been extrapolated up to 100 TeV, to give sigma, rho and b predictions for cosmic ray and future collider energies

    The results of an analysis of inclusive production of γ(πsup(0)), Ksub(s)ysup(0), Λ, anti Λ particles in anti pp interaction at 22.4 GeV/c are presented. The total and topological inclusive cross sections of neutral particles were obtained. The charged multiplicity dependences of the mean number of πsup(0), Ksup(0)/ anti Ksup(0), Λ/ anti Λ productions were studied. The mean number of Λ/ anti Λ particles decreases with increasing charged multiplicity. The KNO scaling hypothesis for πsup(0), Ksub(s)sup(0), Λ particles was confirmed

    The differential distributions over longitudinal and transvers Feynman variables for inclusive γ, Ksub(s)sup(0), Λ production in anti pp interactions at 22.4 GeV/c are presented. The rapidity distributions in the c.m.s. for γ and K 0 /K 0 particles are well described by the quark-antiquark fusion model. In the central region there is some evidence for scaling behaviour of the invariant differential cross sections F for the anti pp → γ+all in the range from 22.4 GeV/c to 100 GeV/c while for the K 0 / K 0 tilde production Frises in this energy interval. A non-zero Λ polarization of -0.414+-0.206 was measured

  9. Feasibility studies of the anti pp{yields}{pi} {sup circle} e{sup +}e{sup -} electromagnetic channel at anti PANDA

    2011-07-01

    Among all possible realizations of quark and antiquark assembly, the nucleon (the proton and the neutron) is the most stable of all hadrons and consequently has been the subject of intensive studies. Mass, shape, radius and more complex representations of its internal structure are measured since several decades using different probes. The proton (spin 1/2) is described by the electric G{sub E} and magnetic G{sub M} form factors which characterise its internal structure. The simplest way to measure the proton form factors consists in measuring the angular distribution of the electron-proton elastic scattering accessing the so-called Space-Like region where q{sup 2}{<=}0. Using the crossed channel anti pp<->e{sup +}e{sup -}, one accesses another kinematical region, the so-called Time-Like region where q{sup 2}>0. However, due to the anti pp <->e{sup +}e{sup -} threshold q{sup 2}{sub th}, only the kinematical domain q{sup 2}>q{sup 2}{sub th}> 0 is available. To access the unphysical region, one may use the anti pp{yields}{pi} {sup circle} e{sup +}e{sup -} reaction where the {pi} {sup circle} takes away a part of the system energy allowing q{sup 2} to be varied between q{sup 2}{sub th} and almost 0. This thesis aims to show the feasibility of such measurements with the anti PANDA detector which will be installed on the new high intensity antiproton ring at the FAIR facility at Darmstadt. To describe the anti pp {yields} {pi} {sup circle} e{sup +}e{sup -} reaction, a Lagrangian based approach is developed. The 5-fold differential cross section is determined and related to linear combinations of hadronic tensors. Under the assumption of one nucleon exchange, the hadronic tensors are expressed in terms of the 2 complex proton electromagnetic form factors. An extraction method which provides an access to the proton electromagnetic form factor ratio R= vertical stroke G{sub E} vertical stroke / vertical stroke G{sub M} vertical stroke and for the first time in an

    This note complements the paper titled: ``Production of deuterons, tritons, $^{3}$He nuclei and their anti-nuclei in pp collisions at $\\sqrt{s}$~=~0.9, 2.76 and 7~TeV'' with additional material related to Monte Carlo simulations necessary to compare the results with lower energy experiments. It describes a coalescence-based afterburner for QCD-inspired event generators, which allows the generation of light nuclei, hyper-nuclei and their charge conjugates in proton--proton (pp) collisions at LHC energies. The event generators with the afterburner are able to reproduce the differential cross sections of light (anti-)nuclei ($A<4)$ with the same degree of agreement as those of protons and anti-protons at the same momentum per nucleon. They also explain the transverse momentum dependence of the coalescence parameters as the result of hard scattering effects.

  11. Investigation of the anti pp → xi (2220) → K/sub s/K/sub s/ reaction at LEAR

    1985-01-01

    Measurement of the total and differential cross section of the reaction anti pp → K/sub s/K/sub s/ in a fine momentum scan corresponding to the mass range of the xi (2220) was proposed. The mass and width of such a resonance coupling to anti pp can be determined to better than 500 keV and additionally the spin can be established from the differential cross section. Only modest additions to our existing threshold detector and antiproton beam intensities currently available at LEAR are required for these studies. 14 refs

    The UA1 group has reported a large B-barB production cross-section at Santi-ppS energies (∼ 1 μb). Following this observation it is indicated how the large rate of B mesons produced in anti-pp collisions could be used to search for and detect various rate decays. Several specific decays and the theoretical expectations and implications of the detections of these decays have been considered. Tests of the GIM model, horizontal symmetry and CP violation can be carried out in this manner. A spectrometer consisting of a CCD telescope, a magnetized muon detection spectrometer and an e.m. shower detector is described

  13. Anti-pp,. cap alpha cap alpha. and p. cap alpha. elastic scattering at high energies and Chou-Yang conjecture

    1987-03-01

    The recent experimental measurements for anti-pp and ..cap alpha cap alpha.. elastic scattering at high energies have shown that the Chou-Yang conjecture regarding the relationship between the electromagnetic and the hadronic form factor of a particle is only an approximation. A new ansatz has been proposed to obtain hadronic form factors of proton and the ..cap alpha..-particle. These form factors have been used to explain the various characteristics of anti-pp, ..cap alpha cap alpha.. and p..cap alpha.. elastic scattering at high energies.

    We study the correlations that arise from the formation of plasma droplets in high multiplicity events observed in recent FNAL anti pp collisions at √s=1.8 TeV. We show how the correlation between the final particles depends on the droplet size and density and on correlations between the droplets. We find that the two-particle correlation function R 2 could provide a clear signal for the formation of droplets. (orig.)

    In this paper, we introduced thermal annealing treatment as an effective way of increasing the nanoscale roughness of a semi-crystalline polymer surface. Annealing treatment applied to a biomimetic microscale pattern of rice leaf to achieve a superhydrophobic surface with a hierarchical roughness. Resulted surfaces was characterized by XRD, AFM and FE-SEM instruments and showed an increase of roughness and cristallinity within both time and temperature of treatment. These two parameters also impact on measured static contact angle up to 158°. Bacterial attachment potency has an inverse relationship with the similarity of surface pattern dimensions and bacterial size and due to that, thermal annealing could be an effective way to create anti-bacterial surface beyond its effect on water repellency. Point in case, the anti-bacterial properties of produced water-repellence surfaces of PP were measured and counted colonies of both gram-negative (E. coli) and gram-positive (S. aureus) bacteria reduced with the nature of PP and hierarchical pattern on that. Anti-bacterial characterization of the resulted surface reveals a stunning reduction in adhesion of gram-positive bacteria to the surface. S. aureus reduction rates equaled to 95% and 66% when compared to control blank plate and smooth surface of PP. Moreover, it also could affect the other type of bacteria, gram-negative (E. coli). In the latter case, adhesion reduction rates calculated 66% and 53% when against to the same controls, respectively.

    This Letter carries out a sensitive ( approximately 5 events/nb) search for narrow pp states at the Brookhaven National Laboratory multiparticle spectrometer. No evidence is found for such states in the mass range 1900-2400 MeV/c/sup 2/ in the reaction pi /sup -/p to p pi /sup -/pp at 16 GeV/c. In particular, the pp states at 2020 and 2200 MeV/c/sup 2/ previously reported in a CERN Omega -spectrometer experiment are not observed. (7 refs).

    A search has been made for scalar leptoquark pair production with the upgraded UA2 detector at the CERN anti pp Collider at √s=630 GeV, investigating decays of the leptoquark into a quark and either an electron or an electron neutrino. From an event sample corresponding to an integrated luminosity of 13 pb -1 a lower limit has been determined for the mass of first generation leptoquarks, yielding 67 GeV (95% CL) for a scalar leptoquark decaying with a 50% branching ratio into a quark and an electron.

    1976-01-01

    The inclusive spectra for inelastic anti-pp-interactions are investigated. Distributions of the transverse momentum squared for negative and positive particles as well as for identified protons have been obtained. The missing mass-squared distributions to the identified protons have been determined for different topologies of the experiment. The rapidity and target fragmentation cross-sections distributions have been obtained for the anti-pp → π - (π + )+X reactions in the center-of-mass-system. Average characteristics of the transverse momentum distribution show similar features as well as those obtained at higher than 22.4 GeV/c elsewhere. The upper limit of the antiproton diffraction dissociation cross section is 3.68+-0.45 mb. In the central region a charge asymmetry has been observed, the asymmetry parameter being equal to 0.15+-0.01

    The ratios of yields of anti-baryons to baryons probes the mechanisms of baryon-number transport. Results for anti-proton/proton, anti-$\\Lambda/\\Lambda$, anti-$\\Xi^{+}/\\Xi^{-}$ and anti-$\\Omega^{+}/\\Omega^{-}$ in pp collisions at $\\sqrt{s}$ = 0.9, 2.76 and 7 TeV, measured with the ALICE detector at the LHC, are reported. Within the experimental uncertainties and ranges covered by our measurement, these ratios are independent of rapidity, transverse momentum and multiplicity for all measured energies. The results are compared to expectations from event generators, such as PYTHIA and HIJING/B, that are used to model the particle production in pp collisions. The energy dependence of anti-proton/proton, anti-$\\Lambda/\\Lambda$, anti-$\\Xi^{+}/\\Xi^{-}$ and anti-$\\Omega^{+}/\\Omega^{-}$, reaching values compatible with unity for $\\sqrt{s}$ = 7 TeV, complement the earlier anti-proton/proton measurement of ALICE. These dependencies can be described by exchanges with the Regge-trajectory intercept of $\\alpha_J$ ≈ 0.5, ...

  1. Surface/state correspondence and bulk local operators in pp-wave holography

    Directory of Open Access Journals (Sweden)

    Nakwoo Kim

    2015-12-01

    Full Text Available We apply the surface/state correspondence proposal of Miyaji et al. to IIB pp-waves and propose that the bulk local operators should be instantonic D-branes. In line with ordinary AdS/CFT correspondence, the bulk local operators in pp-waves also create a hole, or a boundary, in the dual gauge theory as pointed out by H. Verlinde, and by Y. Nakayama and H. Ooguri. We also present simple calculations which illustrate how to extract the spacetime metric of pp-waves from instantonic D-branes in boundary state formalism.

  2. Analysis of the alignment of momenta in anti pp interactions at 22.4 GeV/c

    International Nuclear Information System (INIS)

    Boos, E.G.; Ermilova, D.I.; Samoilov, V.V.

    1979-01-01

    Analyzed were about 25000 inelastic anti pp events with charge multiplicity of 2, 4, 6, 8, 10, obtained with the ''Ludmila'' chamber. The events were reconstructed by the MDTHRESH and HYDRA programs. The results on studying azimuthal correlations in anti pp-interactions are presented. The difference observed between distributions of particle pairs with equal and different charges cannot be explained completely neither by the effect of interference of identical particles, nor by the presence of leading particles or by that of resonances. Studies of the value of planarity point to the alignment of transverse momentum of secondary particles. The alignment does not depend on the multiplicity of charged particles, and it is not connected with the effect of interference of identical particles or with leading particles. An asymmetry is observed in the azimuthal angular distribution of a beam particle in the main axes system, which is not described in the framework of cylindrical phase volume

  3. Experimental analysis in formation of anti-pp interactions between 0. and 1.2 GeV/c: evidence for a anti-pp→5π effect near 1950 MeV/c2

    International Nuclear Information System (INIS)

    Defoix, C.; Dobrzynski, L.; Espigat, P.; Laloum, M.; Ladron de Guevara, P.

    1979-07-01

    An experimental analysis of anti-pp interactions between the anti-pp threshold (√s=1878 MeV) and √s=2100 MeV leads to clear evidence for an s-channel effect in the reaction anti-pp→π + π - π + π - π 0 at 1949+-10 MeV/c 2 (GAMMA approximately 80 MeV/c 2 ). Comparison is made with the backward elastic scattering and charge-exchange behaviors. An interpretation in terms of an object strongly coupled to mesonic decay modes, with a sma-1 or middle-sized elasticity (x<=0.135 + 0.13 (or -0.06)) is given. No significant narrow structure is observed in the backward elastic scattering between 1.9 and 2 GeV. The experimental resolution on √s in this case is 2 MeV

  4. Status and future of the experiment PS 170 (anti pp → e+e-)

    International Nuclear Information System (INIS)

    Duclos, J.

    1985-03-01

    The LEAR experiment PS170 is designed to detect the e +- pairs from anti p-annihilation. It aims to measure the proton form factors in the time like region and the spectrum of vector mesons in the mass range: 1-1,6 GeV. Data have been taken at 300, 600 and 1500 MeV/c incident momenta. The analysis of the 300 MeV/c data gave 200 2-body events: (anti pp → e + e - ), clearly separated from the hadronic background. Values of the form factors are extracted near threshold. The next step will be to accumulate sufficient data to measure separately the electric and magnetic components up to 600 MeV/c. The use of an internal target is considered for measurements at high momenta

    We study the sensitivity of pion interferometry in pp and anti pp collisions at ISR energies to the resonance abundance. We show that those data are not compatible with the full resonance fractions predicted by the Lund model. The preliminary S+S and O+Au data at 200 A GeV are, however, not incompatible with the Lund predictions, although their sensitivity to resonances is significantly weaker than in the pp/anti pp case.

    In the framework of the color-magnetic interaction, we systematically investigate the mass splittings of the QQ anti Q anti q tetraquark states and estimate their rough masses in this work. These systems include the explicitly exotic states cc anti b anti q and bb anti c anti q and the hidden exotic states cc anti c anti q, cb anti b anti q, bc anti c anti q, and bb anti b anti q. If a state around the estimated mass region can be observed, its nature as a genuine tetraquark is favored. The strong decay patterns shown here will be helpful to the experimental search for these exotic states. (orig.)

    Results are presented on measuring the anti pp elastic scattering differential cross section at 22.4 GeV/c over a region of 0.05 2 . The results have been obtained from pictures of the HBC ''Ludmila''. The total elastic cross section σsub(el)=9.0+-0.3 mb and the slope parameter b(s, t=0)=13.1+-0.8 GeVsup(-2) have been found from the data approximated by a quadratic exponential function. The results are compared with the data at similar energies

    1982-01-01

    The comparison of experimental multiplicity distributions for the processes of inelastic anti pp interaction and antiproton diffraction dissociation at 22.4 GeV/c with leading particles removed from event with e + e - annihilation into hadron is presented. The observed similarity of these processes corresponds to the dual parton model predictions

  10. An analysis of anti p, Λ, (anti Λ), Ξ (anti Ξ) and Ω, (anti Ω) production in pp and p-nucleus collisions at lab momenta between 32 and 800 GeV/c

    Geist, W.; Kachelhoffer, T.

    1994-01-01

    The shapes of measured double differential cross sections for inclusive production (-) (-) (-) of p, Λ, Ξ and Ω by protons of various target nuclei are well reproduced by a rather simple model. The double differential cross sections for pp interactions are factorized into longitudinal and transverse terms. Extrapolations to heavier targets are based upon an empirical law. For all (anti-) baryons considered a total of 5 free parameters is needed. (authors)

    The upgraded UA2 detector has collected data corresponding to a total integrated luminosity of 7.5 pb -1 from anti pp collisions at a centre of mass energy of 630 GeV during 1988 and 1989. A search has been performed for the production and decay of the top quark (t) or a member of a hypothetical fourth family (b'). No evidence has been found for such processes. Using the expected rates for production and decay branching ratios from the Standard Model, this implies that the top quark mass is greater than 69(71) GeV/c 2 , and that the b' mass is greater than 54(57) GeV/c 2 , at 95(90)% confidence.

    Inclusive rho 0 production has been investigated in anti pp reactions at 22.4 GeV/c. The total cross section for rho 0 production is 8.1+-2.0 mb. The average number of rhosup(0') s per event is 0.17+-0.03. The average transverse momentum, as obtained by extrapolation of a simple exponential to the psub(T)sup(2) distribution, is 0.52+-0.12 GeV. The Feynman x and center of mass rapidity distributions show rho 0 to be ''centrally'' produced

    2014-01-01

    Full Text Available The HADES collaboration has searched for the anti-kaonic nuclear cluster “ppK−” in p+p collisions by its decay into pΛ. In the course of this analysis several cross checks had to be performed. This report discusses two examples thereof. In one test it was checked whether the presence of background events could introduce a bias on the applied partial wave analysis. The second item discussed here is the extraction of the total pK+Λ production cross section necessary to derive the absolute upper limit on the “ppK−” production cross section.

The mass, width and the product of cross section sigmasub(I) times the branching ratio BR into the final state (K 0 sub(s)π +- π + π - ) are found to be: Msub(I)=2.60+-0.01 GeV/c 2 , GAMMAsub(I) 2 , sigmasub(I).BR approximately 20 μbarn.

    In this work, we study systematically the mass splittings of the qq anti Q anti Q (q = u, d, s and Q = c, b) tetraquark states with the color-magnetic interaction by considering color mixing effects and estimate roughly their masses. We find that the color mixing effect is relatively important for the J{sup P} = 0{sup +} states and possible stable tetraquarks exist in the nn anti Q anti Q (n = u, d) and ns anti Q anti Q systems either with J = 0 or with J = 1. Possible decay patterns of the tetraquarks are briefly discussed. (orig.)

    Results are given on a search for the decay W ± →π ± γ with the UA2 detector in anti pp collisions at √s=630 GeV. No signal for such a process is observed and upper limits on the ratio R=Γ(W ± →π ± γ)/Γ(W ± →e ± ν) -3 and on the branching ratio BR(W ± →π ± γ) -4 are derived at 95% confidence level. (orig.)

    Experimental results are reported for measuring the thermal diffusivity of two polymer species: low density polyethylene (LDPE) and polypropylene (PP). Measurements were taken in unsteady state heat flow conditions around the materials' melting temperature, using a device specially constructed for this purpose. The experimental results for the sample's temperature profile (temperature gradient product) were adjusted with the theoretical results obtained by solving the heat conduction equation...

  6. Light exotic atoms in liquid and gaseous hydrogen and deuterium. Atom anti pp, theory and experiment

    Considered are the de-eXcitation, absorption and Stark mixing processes in light exotic atoms formed in liquid and gaseous hydrogen (deuteriUm) and presented is the new method of the cascade calculations. Atom anti pp is studied in detail, calculated are: the populations of atomic levels, the absorption probabilities, and the X-rays yields. The present-day experimental data are discussed and it is concluded that all of them (but one result), can be easily reconciled with each other and with the theory

  7. Lambda/kaon relative production in anti p + nucleus reactions in terms of a quark recombination diagram

    International Nuclear Information System (INIS)

    Haatuft, A.; Halsteinslid, A.; Breivik, F.O.

    1989-03-01

    The ratio R=N(Λ o )/N(K o S) between the number N(Λ o ) of Λ o 's and the number N(K o s) of the short-lived neutral kaons produced in the reaction anti p + nucleus reactions at low energy has in previous papers been discussed in terms of the fireball model of Cugnon and Vandermeulen and in terms of the reaction anti KN → Λ o π, where the anti K has been produced in the primary reaction anti ppanti KK + X. In this note the ratio R is discussed in terms of the quark model. The results indicate that quark effects may be important for the reaction studied, even if the energy is low. The discussion is based on the assumption that diagrams with connected quark-lines from initial to final state are suppressed, and that valence quarks survive to the final state. This assumption is supported by the results of exclusive anti pp-reactions at low energy, which shows that final states with more than two pions or kaons are more likely than final states with two mesons only, even if low multiplicity is favoured by phase space

    The production and properties of high transverse momentum hadron jets have been measured in the UA2 experiment at the CERN anti pp Colider (√s=540 GeV) using a highly segmented total absorption calorimeter. The characteristics of a sample of two-jet events with invariant mass up to 200 GeV/c 2 are discussed, including measurements of their fragmentation properties, angular and rapidity distributions, and the properties of the additional energy clusters accompanying the two-jet system. Cross sections for inclusive jet production in the jet transverse momentum range between 30 and 100 GeV/c and for the two-jet invariant mass distribution in the mass range from 60-200 GeV/c 2 are reported.

  9. Study of pp{yields}pp{eta} reaction at threshold; Etude de la reaction pp{yields}pp{eta} au seuil

    1994-11-01

    The {eta} production has been studied through the pp {yields} pp{eta} reaction at threshold. Data were taken at the Synchrotron of the ``Laboratoire National Saturne``. The detection in coincidence of the two protons scattered near 0 deg and analysed with the magnetic spectrometer SPES3 allows the reconstruction of missing mass spectra for the {eta} signature. A simulation program which takes into account all the experimental set up characteristics has been realized and tested through the pp {yields} d{pi}{sup +} reaction detected simultaneously with pp {yields} pp{eta}. The generated proton momentum spectra for pp {yields} pp{eta} show a pronounced {eta} mass dependence. This characteristic, connected to the kinematical properties of pp {yields} pp{eta} at threshold, is used to extract the mass of the meson {eta}. The obtained value, m{sub {eta}} = 547.65 {+-} 0.18 MeV, is in good agreement with measurement done recently through the pd {yields} {sup H}e{eta} reaction. The total cross section {sigma}{sub t} of pp {yields} pp{eta} measured at 1260, 1265 and 1300 MeV presents a strong energy dependence. This cross section increases less with energy than the phase-space. The influence of p-p and {eta}-p final state interactions in our measurements is studied. Our results are compared with theoretical predictions and assess the dominant character of the baryonic resonance N{sup *}(1535) in the {eta} mechanism production at threshold. These experimental results give an energy dependence which is not well reproduced by the theoretical predictions. This discrepancy could be an incorrect description of the {eta}-p interaction in the models. (author). 48 refs., 60 figs., 15 tabs.

    The study of bound states, formed by quark c and antiquark anti c (Charmonium), is a source of very important information to understand the basic theory of strong interactions. Experiment E760 at Fermilab is designed to give a precise measurement of the mass and width of the Charmonium states which cannot be formed directly in e + e - collisions. In this experiment, a non magnetic detector system, mounted inside the Antiproton source tunnel, detects the products of collisions of antiprotons, circulating inside the Accumulator vacuum pipe, with an H 2 internal jet target. The excitation curve for resonance formation is obtained by changing in small steps the energy of the Antiproton beam and identifying the resonance through the detection of its electromagnetic decay products. The experiment has been running since the middle of June 1990 and, in the first two months, has collected data for an integrated luminosity of 6.4 pb -1 . Scans were performed at the formation energy for Ψ, Ψ, χ 1 , χ 2 and they have yielded precise measurements of the parameters which characterize these resonances. After a three months shut-down we will resume data taking to study singlet Charmonium states. (orig.)

    All anti pp events at 22.4 GeV/c were separated into nonannihilation (N-group) and enriched annihilation (A-group) events. The mean sphericity value for the A-sample is in accordance with e + e - , K - p and π - p data. The experimental value of for events from the A-sample is larger than the value for N-events for all multiplicities. Mean charge transfer is found to be very sensitive to the dynamics of the process. The experimental value of mean charge transfer is = -0.25 if possible particle misidentification is taken into account. The experimental data are compared with the quark-parton model predictions.

  14. Limitations on anti p-p luminosity with direct injection and stacking of antiprotons

    International Nuclear Information System (INIS)

    Courant, E.D.; Teng, L.C.

    1979-01-01

    If protons of very high energy impinge on a target, a large part of the resulting antiprotons are sufficiently collimated to be injectible into a stacking and accelerating ring. They can then be stacked and injected into the main proton accelerator so as to produce anti p-p collisions without low energy antiproton cooling. A scheme is presented for the VBA, where 20 TeV protons produce 9 x 10 -4 antiprotons per proton at 100 GeV, which are then stacked, accelerated to 1 TeV, and injected into the main ring. With 16 proton pulses of 10 15 protons, one obtains a luminosity of the order of 10 32 cm -2 sec -1 with a beam-beam tune shift of 10 -3 per interaction region. The beams are bunched into 1000 bunches; the orbits are separated by means of relatively modest electostatic electrodes

  15. Initial angular momentum state in pp annihilation at rest

    CERN Document Server

    Bizzarri, R

    1972-01-01

    The author shows that no quantitative statement on the relative importance of initial P-states in pp annihilation can be made. Annihilations in flight indicate that P-wave annihilation into K/sub 1 //sup 0/K/sub 1//sup 0/ is inhibited while annihilation into pi pi is enhanced and might suggest a P-wave contamination approximately 10%. The observatory of the final state K/sub 1//sup 0/K/sub 1//sup 0/n from annihilations at rest indicates that the depression of the K/sub 1//sup 0/K/sub 1//sup 0/ final state is not so important and suggests a P-wave contamination smaller than 4%. Furthermore the successes obtained in the analysis of various final states on the assumption of S-wave annihilation are hard to reconcile with a P-wave contribution bigger than approximately 5%.

    In this article, we study the J{sup PC} = 0{sup ++} and 2{sup ++} QQ anti Q anti Q tetraquark states with the QCD sum rules, and we obtain the predictions M{sub X(cc} {sub anti} {sub c} {sub anti} {sub c,0}{sup {sub +}{sub +)}} =5.99 ± 0.08 GeV, M{sub X(cc} {sub anti} {sub c} {sub anti} {sub c,2}{sup {sub +}{sub +)}} = 6.09 ± 0.08 GeV, M{sub X(bb} {sub anti} {sub b} {sub anti} {sub b,0}{sup {sub +}{sub +)}} = 18.84 ± 0.09 GeV and M{sub X(bb} {sub anti} {sub b} {sub anti} {sub b,2}{sup {sub +}{sub +)}} = 18.85 ± 0.09 GeV, which can be confronted to the experimental data in the future. Furthermore, we illustrate that the diquark-antidiquark type tetraquark state can be taken as a special superposition of a series of meson-meson pairs and that it embodies the net effects. (orig.)

    The reaction p(@3.5 GeV)+p→p+Λ+K{sup +} can be studied to search for the existence of kaonic bound states like ppK{sup −} leading to this final state. This effort has been motivated by the assumption that in p+p collisions the Λ(1405) resonance can act as a doorway to the formation of the kaonic bound states. The status of this analysis within the HADES Collaboration, with particular emphasis on the comparison to simulations, is shown in this work and the deviation method utilized by the DISTO Collaboration in a similar analysis is discussed. The outcome suggests the employment of a partial wave analysis do disentangle the different contributions to the measured pK{sup +}Λ final state.

    New calculations of the quasi-bound state positions in K{sup -}K{sup -}pp kaonic nuclear cluster are performed using non-relativistic four-body Faddeev-type equations in AGS form. The corresponding separable approximation for the integral kernels in the three- and four-body kaonic clusters is obtained by using the Hilbert-Schmidt expansion procedure. Different phenomenological models of anti KN-πΣ potentials with one- and two-pole structure of Λ(1405) resonance and separable potential models for anti K- anti K and nucleon-nucleon interactions, are used. The dependence of the resulting four-body binding energy on models of anti KN-πΣ interaction is investigated. We obtained the binding energy of the K{sup -}K{sup -}pp quasi-bound state ∝ 80-94 MeV with the phenomenological anti KN potentials. The width is about ∝ 5-8 MeV for the two-pole models of the interaction, while the one-pole potentials give ∝ 24-31 MeV width. (orig.)

  19. Spin Correlations of Lambda anti-Lambda Pairs as a Probe of Quark-Antiquark Pair Production

    CERN Document Server

    Ellis, John

    2012-01-01

    The polarizations of Lambda and anti-Lambda are thought to retain memories of the spins of their parent s quarks and antiquarks, and are readily measurable via the angular distributions of their daughter protons and antiprotons. Correlations between the spins of Lambda and anti-Lambda produced at low relative momenta may therefore be used to probe the spin states of s anti-s pairs produced during hadronization. We consider the possibilities that they are produced in a 3P_0 state, as might result from fluctuations in the magnitude of , a 1S_0 state, as might result from chiral fluctuations, or a 3S_1 or other spin state, as might result from production by a quark-antiquark or gluon pair. We provide templates for the p anti-p angular correlations that would be expected in each of these cases, and discuss how they might be used to distinguish s anti-s production mechanisms in pp and heavy-ion collisions.

    Here we explored the potential effect of PP121, a novel dual inhibitor of tyrosine and phosphoinositide kinases, against human esophageal cancer cells. We showed that PP121 exerted potent cytotoxic effect in primary (patient-derived) and established (Eca-109, TE-1 and TE-3 lines) esophageal cancer cells, possibly through activating caspase-3-dependnent apoptosis. PP121 was, however, non-cytotoxic to the normal human esophageal epithelial cells (EECs). At the molecular level, we showed that PP121 blocked Akt-mTOR (mammalian target of rapamycin) activation in esophageal cancer cells, which was restored by introducing a constitutively-active Akt (CA-Akt). Yet, CA-Akt only partly inhibited cytotoxicity by PP121 in Eca-109 cells. Importantly, we showed that PP121 inhibited nuclear factor kappa B (NFκB) signaling activation in esophageal cancer cells, which appeared independent of Akt-mTOR blockage. In vivo, oral administration of PP121 remarkably inhibited Eca-109 xenograft growth in nude mice, and significantly improved mice survival. Further, the immunohistochemistry (IHC) and Western blot assays analyzing xenografted tumors showed that PP121 inhibited Akt-mTOR and NFκB activations in vivo. Together, we demonstrate that PP121 potently inhibits esophageal cancer cells in vitro and in vivo, possibly through concurrently inhibiting Akt-mTOR and NFκB signalings. - Highlights: • PP121 is cytotoxic against primary and established esophageal cancer cells. • PP121 induces caspase-3-dependnent apoptosis in esophageal cancer cells. • PP121 blocks Akt-mTOR activation in esophageal cancer cells. • PP121 inhibits NFκB activation, independent of Akt-mTOR blockage. • PP121 inhibits Eca-109 xenograft growth and Akt-mTOR/NFκB activation in vivo.

    The possible neutral D (*) anti D (*) and B (*) anti B (*) molecular states are studied in the framework of the constituent quark models, which is extended by including the s-channel one-gluon exchange. Using different types of quark-quark potentials, we solve the four-body Schroedinger equation by means of the Gaussian expansion method. The bound states of D (*) anti D (*) with J PC = 1 ++ , 2 ++ and B (*) anti B (*) with J PC = 0 ++ , 1 +- , 1 ++ , 2 ++ are obtained. The molecular states D* anti D with J PC = 1 ++ and B* anti B with J PC = 1 +- are good candidates for X(3872) and Z 0 b (10610), respectively. The dependence of the results on the model parameters is also discussed. (orig.)

    To determine cross sections, average multiplicities and inelasticity coefficients π 0 and Ksub(n), formed in anti pp annihilation interaction at 22.4 GeV/c, data on the differences in the respective characteristics anti pp- and pp-interactions have been used.

    The W and Z bosons masses, m W and m Z , are measured using samples of W→eν and Z→e + e - decays observed in anti pp collisions at √s=630 GeV. The ratio is found to be m W /m Z =0.8813±0.0036±0.0019. This gives a value sin 2 θ W =0.2234±0.0064±0.0033, and in combination with precise m Z measurements from LEP yields m W -80.35±0.33±0.17 GeV. This result is in good agreement with other experiments, and with the standard model for a top quark mass lighter than 250 GeV. (orig.)

    The intermittency effect has been observed in pp collisions at 360 GeV/c and the strength decreases with the increase in multiplicity. The low multiplicity events in pp data (n ch ≤ 8), anti pp collisions (n ch ≤ 15) at Collider energy and elementary interaction (e + e - , μp) samples have almost the same strength. Most likely, few sources seem to contribute at lower multiplications. The intermittency effect is less in pp data compared to e + e - data, however it is fairly strong as compared to nucleus data. The presently used hadronization models DPM, LUND and FRITIOF do not reproduce the results fully. (orig.)

    In the field of low energy QCD the effective description of interactions between ground state hadrons plays a major role in nuclear physics. One of these interactions occurs between anti-kaons and nucleons, and is a topic of a long standing interest. A specific attention is lately drawn to the possible existence of bound states between anti Ks and nucleons. This old concept is based on the idea that the attractive interaction between anti-kaons and nucleons, that already manifests itself as the anti KN-pole of the Λ(1405)-resonance, is strong enough to bind further nucleons by the help of a anti K. The simplest form of these clusters is the anti KNN which consists of a anti K bound to two nucleons. This state might decay into pΛ and is, thus, accessible via open strangeness production in p+p collisions. This work continues the investigations in this field, as a rather puzzling impression is left behind from previous experiments, and further conclusions are needed. The work contains two major data analyses. The first one is dedicated to the anti KN bound state, and selects the semi-exclusive reaction p+p→p+K{sup +}+Λ+X. This was done to investigate the strange resonances Λ(1405) and Σ(1385){sup 0} in their neutral decay channels Σ{sup 0}π{sup 0} and Λπ{sup 0}, respectively. Besides resonance production, several other states contribute to this final state. Their relative strengths have been determined and the obtained production cross sections were in agreement with the results from an independent analysis of the Λ(1405) decay into Σ{sup ±}π{sup -+}, done in a parallel work. To set reasonable constraints for coupled channels calculations in the anti KN sector, a high-precision Λ(1405)-mass spectrum is needed. The obtained yield and uncertainty of the Λ(1405) contribution to the final spectra, however, showed that the required precision is not given in the neutral decay channel.

    The x-rays of anti p atoms were recorded to trace out a strong interaction shift and width to the electromagnetic energy and the radiation width of the low-lying levels. The energy of the levels and consequently the energy of the transitions was calculated by solving numerically the Dirac equation with an electromagnetic potential, taking into account the finite size of the nucleus and the vacuum polarization. Due to the lack of sufficient data, the antiproton-nucleon interaction was not well understood at low energies. In order to separate antiproton-proton from antiproton-neutron interactions, the studies of isotope effects were proposed. (L.M.K.)

  9. Spin correlations of Λanti Λ pairs as a probe of quark-antiquark pair production

    2012-01-01

    The polarizations of Λ and anti Λ are thought to retain memories of the spins of their parent s quarks and anti s antiquarks, and are readily measurable via the angular distributions of their daughter protons and antiprotons. Correlations between the spins of Λ and anti Λ produced at low relative momenta may therefore be used to probe the spin states of s anti s pairs produced during hadronization. We consider the possibilities that they are produced in a 3 P 0 state, as might result from fluctuations in the magnitude of left angle anti ss right angle, a 1 S 0 state, as might result from chiral fluctuations, or a 3 S 1 or other spin state, as might result from production by a quark-antiquark or gluon pair. We provide templates for the p anti p angular correlations that would be expected in each of these cases, and discuss how they might be used to distinguish s anti s production mechanisms in pp and heavy-ion collisions.

The upper limits are, in terms of the cross section integrated over the width, 18 MeV-μb for the final state ΛantiΛ, 18 MeV-μb for K 0 anti K 0 (890) + C.C., and 2 MeV-μb for K/sub S/K/sub L/

    The possibility of observing ΛantiΛ heavy states using the Isabelle storage rings is discussed. Not many particles are known to date to decay into ΛantiΛ. The J/psi is a notable exception, with a branching ratio of about 0.2% (vs. 7% into e + e - and μ + μ - ). However, it is not inconceivable that higher mass states, produced at Isabelle energies, will have substantial branching fractions into ΛantiΛ. If this will indeed be the case, then one may think of getting additional information on the properties of the new states by taking advantage of the parity-violating Λ and antiΛ decays. Detectors, rate and background considerations, and methods of particle detection are discussed

    Merkel cell carcinoma (MCC) is a highly aggressive skin cancer with a high metastatic potential. The majority of MCC cases are caused by the Merkel cell polyomavirus (MCPyV), through expression of the virus-encoded tumour antigens. Whilst mechanisms attributing tumour antigen expression to transformation are being uncovered, little is known of the mechanisms by which MCPyV persists in the host. We previously identified the MCPyV small T antigen (tAg) as a novel inhibitor of nuclear factor kappa B (NF-kB) signalling and a modulator of the host anti-viral response. Here we demonstrate that regulation of NF-kB activation involves a previously undocumented interaction between tAg and regulatory sub-unit 1 of protein phosphatase 4 (PP4R1). Formation of a complex with PP4R1 and PP4c is required to bridge MCPyV tAg to the NEMO adaptor protein, allowing deactivation of the NF-kB pathway. Mutations in MCPyV tAg that fail to interact with components of this complex, or siRNA depletion of PP4R1, prevents tAg-mediated inhibition of NF-kB and pro-inflammatory cytokine production. Comparison of tAg binding partners from other human polyomavirus demonstrates that interactions with NEMO and PP4R1 are unique to MCPyV. Collectively, these data identify PP4R1 as a novel target for virus subversion of the host anti-viral response.

    Full Text Available Hypertensive disorders affect about one third of all people aged 20 and above, and are treated with anti-hypertensive drugs. Preeclampsia (PE is one form of such disorders that only develops during pregnancy. It affects ten million pregnant women globally and additionally causes fetal loss and major newborn disabilities. The syndrome's origin is multifactorial, and anti-hypertensive drugs are ineffective in treating it. Biomarkers are helpful for predict its development. Generic drugs, such as low dose aspirin, were proven effective in preventing preterm PE. However, it does not cure the majority of cases and many studies are underway for fighting PE with extended use of additional generic drugs, or through new drug development programs.This review focuses on placental protein 13 (PP13. This protein is only expressed in the placenta. Impaired PP13 DNA structure and/or its reduced mRNA expression leads to lower blood PP13 level that predict a higher risk of developing PE. Two polymorphic PP13 variants have been identified: (1 The promoter PP13 variant with an “A/A” genotype in the -98 position (versus “A/C” or “C/C”. Having the “A/A” genotype is coupled to lower PP13 expression, mainly during placental syncytiotrophoblast differentiation and, if associated with obesity and history of previous preeclampsia, it accurately predicts higher risk for developing the disorder. (2 A thymidine deletion at position 221 causes a frame shift in the open reading frame, and the formation of an early stop codon resulting in the formation of DelT221, a truncated variant of PP13. In pregnant rodents, both short- and long- term replenishment of PP13 causes reversible hypotension and vasodilation of uterine vessels. Long-term exposure is also accompanied by the development of larger placentas and newborns. Also, only w/t PP13 is capable of inducing leukocyte apoptosis, providing maternal immune tolerance to pregnancy.Based on published data, we

    Exclusive channels in bar pp annihilation at rest provide a powerful tool for studying the meson spectrum below the bar pp threshold. The mesons can be classified in SU(3) multiplets according to their quantum numbers. The states which do not fit into this classification are candidates for new forms of hadronic matter like glueballs, hybrids, and multi-quark states. Recent results on the search for exotic states in exclusive channels of bar pp annihilation at rest are discussed. No less important is the study of the annihilation mechanism. In particular, high-statistic measurements of bar pp annihilation at rest into two-meson final states are an excellent tool for studying quark dynamics. Examples of two-body reactions are presented. 24 refs., 9 figs., 3 tabs

    Measurements of the differential cross sections of the pp -> pp pi sup 0 reaction at 310, 320, 340, 360, 400 and 425 MeV have been carried out at the CELSIUS storage ring in Uppsala. An attempt has been made to describe the distributions obtained in terms of the five partial waves Ss, Ps, Pp, Sd and Ds. The relative contributions from the different states depend significantly upon the energy. For instance, that of the Ss state drops from about 80% at 310 MeV to around 10% at 425 MeV.

Thanks to its excellent particle identification and tracking capabilities, the ALICE detector allows for the measurement of deuterons, tritons, 3He, 4He and their corresponding anti-nuclei. Moreover, the secondary vertices from the mesonic decays of (anti-)hypernuclei can ...

    OBJECTIVE To describe the general seroprevalence of anti-Sarcocystis neurona and anti-Neospora hughesi antibodies among healthy equids by use of indirect fluorescent antibody tests and determine potential risk factors for seropositivity. DESIGN Cross-sectional study. SAMPLE Whole blood samples collected from 5,250 equids (1 sample/animal) across 18 states in the United States during October 2013. PROCEDURES Information regarding potential risk factors (geographic region, breed, primary use, sex, and age) was collected along with the blood samples. For each equid, an indirect fluorescent antibody test was used to determine serum titers of antibody against each of the 2 protozoal parasites. Mixed-effects logistic regression models were created to determine ORs for seropositivity. RESULTS The overall seroprevalence of anti-S neurona and anti-N hughesi antibodies in the tested equids was 78% and 34%, respectively. Of the equids, 31% were seropositive and 18% were seronegative for antibodies against both parasites. Factors associated with equids being seropositive for anti-S neurona antibodies were residence in the South, warmblood breed, and age > 5 years. Seroprevalence of anti-N hughesi antibodies did not differ among equids in different states across the country, but warmblood breed and age > 5 years were associated with seropositivity. CONCLUSIONS AND CLINICAL RELEVANCE With regard to risk factors for S neurona and N hughesi exposure and antibody response among tested equids, older age was not unexpected; however, the influences of warmblood breed and geographic location on seropositivity for anti-S neurona antibody but not for anti-N hughesi antibody deserve further investigation.

    Inelastic topological anti np cross sections at 6 GeV/c have been determined based on a study of the charged multiplicity distribution in antideuteron-proton collisions at 12 GeV/c. The data were obtained in an exposure of the ''Ludmila'' JINR 2 m hydrogen bubble chamber at the Serpukhov accelerator. In anti np interactions average charged multiplicity and its ratio to dispersion, /D, were found to be 3.32+-0.13 and 1.86+-0.16, respectively. Comparison with anti pn, anti pp and pp data was made

    The first measurement of the jet mass m{sub jet} of top quark jets produced in t anti t events from pp collisions at √(s) = 8 TeV is reported for the jet with the largest transverse momentum p{sub T} in highly boosted hadronic top quark decays. The data sample, collected with the CMS detector, corresponds to an integrated luminosity of 19.7 fb{sup -1}. The measurement is performed in the lepton+jets channel in which the products of the semileptonic decay t → bW with W → lν where l is an electron or muon, are used to select t anti t events with large Lorentz boosts. The products of the fully hadronic decay t → bW with W → q anti q{sup '} are reconstructed using a single Cambridge-Aachen jet with distance parameter R = 1.2, and p{sub T} > 400 GeV. The t anti t cross section as a function of m{sub jet} is unfolded at the particle level and is used to test the modelling of highly boosted top quark production. The peak position of the m{sub jet} distribution is sensitive to the top quark mass m{sub t}, and the data are used to extract a value of m{sub t} to assess this sensitivity. (orig.)

  1. Mutation of the Kunitz-type proteinase inhibitor domain in the amyloid β-protein precursor abolishes its anti-thrombotic properties in vivo.

    Kunitz proteinase inhibitor (KPI) domain-containing forms of the amyloid β-protein precursor (AβPP) inhibit cerebral thrombosis. KPI domain-lacking forms of AβPP are abundant in brain. Regions of AβPP other than the KPI domain may also be involved with regulating cerebral thrombosis. To determine the contribution of the KPI domain to the overall function of AβPP in regulating cerebral thrombosis we generated a reactive center mutant that was devoid of anti-thrombotic activity and studied its anti-thrombotic function in vitro and in vivo. To determine the extent of KPI function of AβPP in regulating cerebral thrombosis we generated a recombinant reactive center KPI R13I mutant devoid of anti-thrombotic activity. The anti-proteolytic and anti-coagulant properties of wild-type and R13I mutant KPI were investigated in vitro. Cerebral thrombosis of wild-type, AβPP knock out and AβPP/KPI R13I mutant mice was evaluated in experimental models of carotid artery thrombosis and intracerebral hemorrhage. Recombinant mutant KPI R13I domain was ineffective in the inhibition of pro-thrombotic proteinases and did not inhibit the clotting of plasma in vitro. AβPP/KPI R13I mutant mice were similarly deficient as AβPP knock out mice in regulating cerebral thrombosis in experimental models of carotid artery thrombosis and intracerebral hemorrhage. We demonstrate that the anti-thrombotic function of AβPP primarily resides in the KPI activity of the protein. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Pyrvinium pamoate (PP) is an FDA-approved classical anthelmintic, but is now attracting particular attention as an anti-cancer drug after recent findings of its potent cytotoxicity against various cancer cell lines only during glucose starvation, as well as its anti-tumor activity against hypovascular pancreatic cancer cells transplanted in mice. The molecular mechanisms by which PP promotes such preferential toxicity against cancer cells are currently under extensive investigation. PP suppressed the NADH-fumarate reductase system that mediates a reverse reaction of the mitochondrial electron-transport chain complex II in anaerobic organisms such as parasitic helminthes or mammalian cells under tumor microenvironment-mimicking hypoglycemic/hypoxic conditions, thereby inhibiting efficient ATP production. PP also inhibited the unfolded protein response induced by glucose starvation, thereby inhibiting the proliferation of pancreatic cancer cells. Even under normoglycemic/normoxic conditions, PP suppressed the mitochondrial electron-transport chain complex I and thereby STAT3, inhibiting the proliferation of myeloma/erythroleukemia cells. Here, we review accumulating knowledge on its working mechanisms and evaluate PP as a novel anti-cancer drug that targets mitochondrial respiration.

    Full Text Available PP4 is a serine/threonine phosphatase required for immunoglobulin (Ig VDJ recombination and pro-B/pre-B cell development in mice. To elucidate the role of PP4 in mature B cells, we ablated the catalytic subunit of murine PP4 in vivo utilizing the CD23 promoter and cre-loxP recombination and generated CD23(crePP4(F/F mice. The development of follicular and marginal zone B cells was unaffected in these mutants, but the proliferation of mature PP4-deficient B cells stimulated by in vitro treatment with either anti-IgM antibody (Ab or LPS was partially impaired. Interestingly, the induction of CD80 and CD86 expression on these stimulated B cells was normal. Basal levels of serum Igs of all isotypes were strongly reduced in CD23(crePP4(F/F mice, and their B cells showed a reduced efficiency of class switch recombination (CSR in vitro upon stimulation by LPS or LPS plus IL-4. When CD23(crePP4(F/F mice were challenged with either the T cell-dependent antigen TNP-KLH or the T cell-independent antigen TNP-Ficoll, or by H1N1 virus infection, the mutant animals failed to form germinal centers (GCs in the spleen and the draining mediastinal lymph nodes, and did not efficiently mount antigen-specific humoral responses. In the resting state, PP4-deficient B cells exhibited pre-existing DNA fragmentation. Upon stimulation by DNA-damaging drug etoposide in vitro, mutant B cells showed increased cleavage of caspase 3. In addition, the mutant B cells displayed impaired CD40-mediated MAPK activation, abnormal IgM-mediated NF-κB activation, and reduced S phase entry upon IgM/CD40-stimulation. Taken together, our results establish a novel role for PP4 in CSR, and reveal crucial functions for PP4 in the maintenance of genomic stability, GC formation, and B cell-mediated immune responses.

    In this work, the K anti K* interaction is studied in a quasipotential Bethe-Salpeter equation approach combined with the one-boson-exchange model. With the help of the hidden-gauge Lagrangian, the exchanges of pseudoscalar mesons (π and η) and vector mesons (ρ, ω and φ) are considered to describe the K anti K* interaction. Besides the direct vector-meson exchange which can be related to the Weinberg-Tomozawa term, pseudoscalar-meson exchanges also play important roles in the mechanism of the K anti K* interaction. The poles of scattering amplitude are searched to find the molecular states produced from the K anti K* interaction. In the case of quantum number I{sup G}(J{sup PC}) = 0{sup +}(1{sup ++}), a pole is found with a reasonable cutoff, which can be related to the f{sub 1}(1285) in experiment. Another bound state with 0{sup -}(1{sup +-}) is also produced from the K anti K* interaction, which can be related to the h{sub 1}(1380). In the isovector sector, the interaction is much weaker and a bound state with 1{sup +}(1{sup +}) relevant to the b{sub 1}(1235) is produced but at a larger cutoff. Our results suggest that in the hadronic molecular state picture the f{sub 1}(1285) and b{sub 1}(1235) are the strange partners of the X(3872) and Z{sub c}(3900), respectively. (orig.)

  8. Effect of mouse antisera targeting the Phlebotomus papatasi midgut chitinase PpChit1 on sandfly physiology and fitness

    Full Text Available In sandflies, the absence of the peritrophic matrix (PM affects the rate of blood digestion. Also, the kinetics of PM secretion varies according to species. We previously characterised PpChit1, a midgut-specific chitinase secreted in Phlebotomus papatasi (PPIS that is involved in the maturation of the PM and showed that antibodies against PpChit1 reduce the chitinolytic activity in the midgut of several sandfly species. Here, sandflies were fed on red blood cells reconstituted with naïve or anti-PpChit1 sera and assessed for fitness parameters that included blood digestion, oviposition onset, number of eggs laid, egg bouts, average number of eggs per bout and survival. In PPIS, anti-PpChit1 led to a one-day delay in the onset of egg laying, with flies surviving three days longer compared to the control group. Anti-PpChit1 also had a negative effect on overall ability of flies to lay eggs, as several gravid females from all three species were unable to lay any eggs despite having lived longer than control flies. Whereas the longer survival might be associated with improved haeme scavenging ability by the PM, the inability of females to lay eggs is possibly linked to changes in PM permeability affecting nutrient absorption.

  9. pp and ̄pp elastic scattering

    Full Text Available We present an analysis of pp and ̄pp elastic scattering in terms of various exchanges. Three-gluon exchange dominates at large t, and single-pomeron exchange at small t. The dip seen in high-energy pp scattering is provided by the interference of both of these with double-pomeron exchange. We predict that this dip will not be found in high-energy ̄pp scattering. The dip that is seen in low-energy ̄pp scattering is the result of the additional presence of reggeon-pomeron exchange.

    The mass of the top quark is measured using a sample of $t\\bar{t}$ candidate events with one electron or muon and at least four jets in the final state, collected by CMS in pp collisions at $\\sqrt{s}$ = 7 TeV at the LHC. A total of 5174 candidate events is selected from data corresponding to an integrated luminosity of 5.0 inverse femtobarns. For each event the mass is reconstructed from a kinematic fit of the decay products to a $t\\bar{t}$ hypothesis. The top-quark mass is determined simultaneously with the jet energy scale (JES), constrained by the known mass of the W boson in q anti-q decays, to be 173.49 $\\pm$ 0.43 (stat.+JES) $\\pm$ 0.98 (syst.) GeV.

    The decay J/ψ→ωp anti p is studied using a 5.8 x 10 7 J/ψ event sample accumulated with the BES II detector at the Beijing Electron-Positron Collider. The decay branching fraction is measured to be B(J/ψ→ωp anti p)=(9.8±0.3±1.4) x 10 -4 . No significant enhancement near the pp mass threshold is observed, and an upper limit of B(J/ψ→ωX(1860))B(X(1860)→pp) -5 is determined at the 95% confidence level, where X(1860) designates the near-threshold enhancement seen in the p anti p mass spectrum in J/ψ→γp anti p decays.

    The possible neutral D{sup (*)} anti D{sup (*)} and B{sup (*)} anti B{sup (*)} molecular states are studied in the framework of the constituent quark models, which is extended by including the s-channel one-gluon exchange. Using different types of quark-quark potentials, we solve the four-body Schroedinger equation by means of the Gaussian expansion method. The bound states of D{sup (*)} anti D{sup (*)} with J{sup PC} = 1{sup ++}, 2{sup ++} and B{sup (*)} anti B{sup (*)} with J{sup PC} = 0{sup ++}, 1{sup +-}, 1{sup ++}, 2{sup ++} are obtained. The molecular states D* anti D with J{sup PC} = 1{sup ++} and B* anti B with J{sup PC} = 1{sup +-} are good candidates for X(3872) and Z{sup 0}{sub b}(10610), respectively. The dependence of the results on the model parameters is also discussed. (orig.)

    The mass of the top quark is measured using a sample of t t-bar candidate events with one electron or muon and at least four jets in the final state, collected by CMS in pp collisions at sqrt(s) = 7 TeV at the LHC. A total of 5174 candidate events is selected from data corresponding to an integrated luminosity of 5.0 inverse femtobarns. For each event the mass is reconstructed from a kinematic fit of the decay products to a t t-bar hypothesis. The top-quark mass is determined simultaneously with the jet energy scale (JES), constrained by the known mass of the W boson in q anti-q decays, to be 173.49 +/- 0.43 (stat.+JES) +/- 0.98 (syst.) GeV.

    The production of long-lived negative secondaries, including [pi][sup -], K[sup -], antiprotons (anti p) and antideuterons (anti d) at 0deg in Si+Au, Si+Cu, and Si+Al collisions at the BNL-AGS has been measured using a double-bend, double-focussing spectrometer. The anti p rapidity spectra from all three targets are well fit by Gaussians centered (anti y = 1.7 - 1.8) at mid-rapidity, and are consistent with production in nucleon-nucleon first collisions. The anti d/anti p[sup 2] ratio in Si+Al collisions is lower by a factor of 10 than that seen in p+p and p+A collisions. (orig.).

    2013-04-18

    The present work investigates the vacuum properties of the hyperon resonances {Sigma}(1385){sup +} and {Lambda}(1405). For this purpose, p+p reactions at 3.5 GeV kinetic beam energy were analyzed. By using simulations and a special background method, the Breit-Wigner mass and width of the {Sigma}(1385){sup +} could be determined. Furthermore, its production dynamics were studied in different angular distributions. In this context indications were found that the {Sigma}(1385){sup +} partially stems from the decay of a heavy {Delta}-resonance. The investigation of the {Lambda}(1405) was based on similar analysis methods. After acceptance and efficiency corrections, the spectral shape of the {Lambda}(1405) could be extracted. Here a mass shift of this particle to masses below 1400 MeV/c{sup 2} was found. This might reveal important information about the two pole structure of the {Lambda}(1405) and its influence on the low energy anti KN interaction.

    The difference between antiproton annihilation and pp interactions has been discussed. Charged particle multiplicity distributions in anti pp-interactions at 22.4 GeV/c were used to obtain antiproton annihilation characteristics. The comparison of the topological cross section of antipp interactions with those of non-diffractive pp interactions confirms the validity of dual unitarization

    A measurement of the t anti tZ and t anti tW production cross sections in final states with either two same-charge muons, or three or four leptons (electrons or muons) is presented. The analysis uses a data sample of proton-proton collisions at √(s) = 13 TeV recorded with the ATLAS detector at the Large Hadron Collider in 2015, corresponding to a total integrated luminosity of 3.2 fb{sup -1}. The inclusive cross sections are extracted using likelihood fits to signal and control regions, resulting in σ{sub t} {sub anti} {sub tZ} = 0.9 ± 0.3 pb and σ{sub t} {sub anti} {sub tW} = 1.5 ± 0.8 pb, in agreement with the Standard Model predictions.

    Novel means to reduce phosphate input into poultry feeds and increase its retention would preserve world phosphate reserves and reduce environmental impact of poultry production. Here we show that a maternally derived antibody to a fibroblast growth factor-23 (FGF-23) peptide (GMNPPPYS) alleviated phosphorus deficiency in chicks fed low non-phytate phosphorus (nPP) diets. White Leghorn laying hens were vaccinated with either an adjuvant control or the synthetic FGF-23 peptide, and chicks with control or anti-FGF-23 maternal antibodies were fed a diet containing either 0.13 or 0.45% nPP (experiment 1), and 0.20 or 0.45% nPP (experiment 2) for 14 d. In both experiments, decreasing nPP from 0.45 to 0.13 or 0.20% decreased BW gain, G:F, excreta phosphorus, plasma phosphate, and plasma FGF-23 at all time periods examined (nPP main effect, P posture scores (d 7, 14) and bone lesion scores (d 14) decreased and plasma phosphate (d 14) increased in anti-FGF-23 chicks fed 0.13% nPP, compared to those with control antibody on the same diet (P < 0.05). In experiment 2, chicks with maternal anti-FGF-23 antibody had increased tibiotarsi ash (d 14), and plasma phosphate (d 14) and 1,25(OH)2D3 (d 14) levels, compared to chicks with control antibody (antibody main effect, P < 0.05). BW gain and G:F were increased in chicks with anti-FGF-23 antibody fed 0.20% nPP, compared to control antibody chicks on the same diet, at all time periods examined (P < 0.05). In conclusion, maternally-derived anti-FGF-23 antibody increased phosphorus retention in chicks fed diets containing either 0.13 or 0.20% nPP and thereby, reduced signs of phosphorus deficiency. © 2016 Poultry Science Association Inc.

    The effects of PMMA and PP-g-PMMA on the oxidation of polypropylene (PP) have been studied. The mixing was done in Laboplastomill at the temperature of 200 o C, and screw speed of 20 rpm, for 5 minutes. The PMMA concentrations were 1, 2, 5, and 10% by weight, and PP-g-PMMA (12% grafting) 5, 10, and 20% by weight. Mechanical properties (tensile strength (Tb) and elongation at break (Eb)( of the mixture decreased with the increase of PMMA content over 5%. The addition of PMMA over 3% produced non-transparent film. Electron beam irradiation at the dose of 5, 10, 30, and 50 kGy was carried out to accelerate the matrix oxidation is accelerated. The optimum properties of PP/PMMA blends can be achieved by addition of maximum 2% PMMA either direct as PMMA or as compatibilizer (PP-g-PMMA). (authors)

    A search for the decays of the B+ c meson to pp-π+ is performed for the first time using a data sample corresponding to an integrated luminosity of 3.0 fb-1 collected by the LHCb experiment in pp collisions at centre-of-mass energies of 7 and 8 TeV. No signal is found and an upper limit, at 95%

    We have measured the inclusive production properties of D and anti D mesons produced from pp interations at √s = 27.4 GeV. The differential production cross section is well represented by the empirical form d 2 σdx F /dP T 2 = 1/2 [σ(D/anti D)(n+1) b](1-vertical strokex F vertical stroke) n exp(-bp T 2 ) with n = 4.9±0.5, b = (1.0±0.1) (GeV/c) -2 , and the inclusive D/anti D cross section σ(D/anti D) is (30.2±3.3) μb. The QCD fusion model predicts D/anti D production which is in good agreement with our data except for the magnitude of the cross section which depends sensitively on the assumed mass of the charm quark.

    In the search for heavy, narrow exotic states such as baryonium or glueballs, carried out so far, various methods of high- and low-energy formation, and e + e - reactions were used. In particular, a search for baryonium states below threshold (M/sub x/ less than or equal to M/sub anti pp/ has shown some evidence for a few states. However, the results of these measurements suffer from poor statistics. Because of the relatively low level of confidence in these results it would be highly desirable to compare them with new measurements of better statistics, now available at the CERN low-energy antiproton ring, LEAR, and with independent measurements based on techniques hitherto not used, which the quality of LEAR now makes feasible

    We study the inclusive production of J/{psi} and (2S) mesons originating from the decays of bottom-flavored hadrons produced in p anti p collisions at the Fermilab Tevatron and in pp collisions at the CERN LHC. We work at next-to-leading order in the general-mass variable-flavor-number scheme (GM-VFNS) implemented with nonperturbative fragmentation functions fitted to e{sup +}e{sup -} data of inclusive b-hadron production exploiting their universality. The three-momentum distributions of the charmonia are extracted from B-decay data in the framework of nonrelativistic-QCD factorization. Comparing the theoretical predictions thus obtained with transverse-momentum distributions measured by the CDF II, ALICE, ATLAS, CMS, and LHCb Collaborations, we find excellent overall agreement as for both absolute normalization and lineshape, which provides a nontrivial test of the GM-VFNS over wide ranges of center-of-mass energy, transverse momentum, and rapidity.

    A combined analysis of the published data on the pp → dK +¯0 reaction at excess energies of 47.4MeV and 104.7MeV is presented that takes into account final-state interactions in both the K +¯0 and ¯0 d channels. The strong attraction of the antikaons with nucleons, already noted for the ppppK + K - reaction, leads here to very different ¯0 d and K+d distributions, with the former being dominantly in an s -wave and the latter in a p -wave. Evidence is also found from the K +¯0 distributions for the production of the a 0 +(980) scalar resonance. The inclusion of both final-state interactions improves the description of the energy dependence of the pp → dK +¯0 total cross-section.

    Full Text Available Leishmaniasis is a vector-borne disease caused by protozoan parasites of the genus Leishmania. Our knowledge of protein phosphatases (PPs and their implication in signaling events is very limited. Here we report the expression, characterization and mutagenesis analysis of a novel protein phosphatase 5 (PP5 in Leishmania major. Recombinant PP5 is a bona fide phosphatase and is enzymatically active. Site-directed mutagenesis revealed auto-inhibitory roles of the N-terminal region. This is a rational first approach to understand the role of PP5 in the biology of the parasite better as well as its potential future applicability to anti-parasitic intervention.

    Charm spectroscopy has recently gained renewed attention, due to confirmations and new observations published by LHCb. Despite of the excellent performance of the CERN experiments, still limitations exist, that do not allow to perform the measurement of the width (Γ) of narrow states with Γ ≤ 1 MeV. The measurement of the D{sub s0}{sup *}(2317) and the D{sub s1}(2460) width is a crucial point to discriminate among theoretical models, and to reveal their nature. One of the major advantage of the future PANDA experiment at FAIR is the excellent momentum beam resolution of about Δp/p=5 x 10{sup -5}, allowing energy scans with an energy resolution down to ΔE ∼ 26 keV. We present a method to measure the width of the D{sub s0}{sup *}(2317), and for the first time a complete full simulation performed with PandaRoot is shown. Feasibility studies for assumption of different signal cross sections are shown, to accommodate the incomplete experimental and theoretical knowledge of the corresponding process of interest. A proposal for a threshold scan for the production reaction anti pp → D{sub s}{sup -}D{sub s0}{sup *}(2317){sup +} in 100-keV-steps is presented, together with an estimate of the competitiveness of PANDA in this field, assuming an average luminosity of L=10{sup 31} cm{sup -1}s{sup -1}.

    Recent research suggests that anti-bullying laws may be effective in reducing risk of bullying victimization among youth, but no research has determined whether these laws are also effective in reducing disparities in bullying. The aim of this paper was to evaluate the effectiveness of anti-bullying legislation in reducing disparities in sex- and weight-based bullying and cyberbullying victimization. Data on anti-bullying legislation were obtained from the U.S. Department of Education, which commissioned a systematic review of 16 key components of state laws in 2011. States were also categorized based on whether their legislation enumerated protected groups and, if so, which groups were enumerated. These policy variables from 28 states were linked to individual-level data on bullying and cyberbullying victimization from students in 9th through 12th grade participating in the 2011 Youth Risk Behavior Surveillance System study (N=79,577). Analyses were conducted in 2016. There was an absence of any kind of moderating effect of anti-bullying legislation on weight-based disparities in bullying and cyberbullying victimization. Only state laws with high compliance to Department of Education enumeration guidelines were associated with lower sex-based disparities in bullying victimization. Anti-bullying policies were not associated with lower weight-based disparities in bullying and cyberbullying victimization among youth, and only one form of policies (high compliance to Department of Education enumeration guidelines) was associated with lower sex-based disparities in bullying victimization. Results therefore suggest that anti-bullying legislation requires further refinement to protect youth who are vulnerable to bullying victimization.

  11. Anti-deuteron sensitivity studies at LHCb

    Measurements of anti-deuterons in collider experiments can help to reduce systematic uncertainties in indirect searches for dark matter. Two predominant unknowns in these searches are the production of secondary anti-deuterons in the cosmos from spallation processes, and anti-deuteron production from annihilating dark matter. LHCb is a forward spectrometer on the LHC ring, designed to measure b-hadron decays from high energy proton-proton collisions. With the detector's excellent particle identification capabilities, deuteron and anti-deuteron measurements at LHCb could help to parametrise the two cosmological processes. Recent studies of (anti-)deuteron identification at LHCb and the prospects for measuring prompt (anti-)deuterons from pp-collisions will be presented, as well as a working analysis of b-baryrons decaying to deuterons.

    Recently the colliding beam goals at Fermilab have been redirected toward 2 TeV c.m. pp physics to be done in the Tevatron. The booster-main ring complex will be the proton injector and the source of protons for anti-proton production. Consequently, the emphasis of recent studies in the main ring has been directed at those problems which arise from the beam manipulation necessary for the pp scenario. These studies are divided into three categories: 1) true storage studies directed toward revealing problems and techniques likely to apply to storage in the Tevatron, 2) beam manipulations necessary for the production of anti-protons, and 3) beam manipulations necessary for producing single proton bunches containing 10/sup 11/ protons each. 16 refs

    Oxidative stress may have a key pathogenetic role in neurodegenerative diseases including Alzheimer's disease (AD). While there is evidence that some amyloid-b (Ab) peptides can initiate oxidative stress at micromolar doses, there is also some evidence that oxidative stress increases the concentration of the b-protein precursor (bPP) and the potential for increased formation of the Ab peptides. The following studies were performed to test the hypothesis that fragments of bPP could be antioxidants and hence that oxidative stress might be an early event in AD. We found that several fragments of bPP, including the Ab peptides, inhibit ascorbate-stimulated lipid peroxidation (ASLP) in membrane fragment preparations of postmortem human brain. In contrast, other fragments of bPP enhance ASLP. These data indicate that bPP or fragments of bPP could play a key role in the redox status of cells and that alterations in bPP processing could have profound effects on the cellular response to oxidative stress.

    The mechanism which is behind the production of light (anti–)nuclei in ultra-relativistic collisions is one of the open questions in high-energy physics. We present the preliminary results obtained from the analyses of the (anti-)deuteron production for two different data samples collected in the LHC run 2: pp collisions at $\\sqrt{s}=13$ TeV and Pb–Pb collisions at $\\sqrt{s_{\\rm NN}}=5.02$ TeV. In particular, the production yields, the ratio between the production of anti-matter and matter, the d/p ratio and the coalescence parameter $B_2$ are compared for the two colliding systems and discussed in the context of thermal and coalescence models.

    We present a particle-level study of the Standard Model non-resonant Higgs-pair production process in the b anti bb anti b final state, at the Large Hadron Collider at √(s) = 14 TeV. Each Higgs boson is reconstructed from a pair of close-by jets formed with the anti-k{sub t} jet clustering algorithm, with radius parameter R = 0.4. Given the kinematic properties of the produced Higgs bosons, this Higgs reconstruction approach appears to be more suitable than the use of largeradius jets that was previously proposed in the literature.We find that the sensitivity for observing this final state can be improved significantly when the full set of uncorrelated angular and kinematic variables of the 4b system is exploited, leading to a statistical significance of 1.8 per experiment with an integrated luminosity of 3 ab{sup -1}.

    1982-05-01

    We present results for the decays of psi(3100) into baryon and hyperon final states. The sample studied here consists of 1.3 million produced psi decays. The decays into nonstrange baryons agree well with currently established results, but with better statistics. In addition, significant resonance formation in multibody final states is observed. The decay psi → anti ppγ, the first direct photon decay of the psi involving baryons in the final state, is presented and the theoretical implications of the decays are briefly explored. Several new decays of the psi involving strange baryons are explored, including the first observations of three body final states involving hyperons. The I-spin symmetry of the strong decay psi → baryons has clearly been observed. The reduced matrix elements for psi → B anti B are presented for final states of different SU(3) content. The B 8 anti B 8 results are in excellent agreement with the psi being an SU(3) singlet as are the results for psi → B 10 anti B 10 . We present the first evidence for the SU(3) violating decays of the type psi → B 8 anti B 10 + c.c.. Angular distributions for psi → B 8 anti B 8 are presented and compared with theoretical predictions. Statistics are limited, but the data tends to prefer other than a 1 + Cos 2 theta distribution

  19. Study of pp→ppη reaction at threshold

    1994-11-01

    The η production has been studied through the ppppη reaction at threshold. Data were taken at the Synchrotron of the ''Laboratoire National Saturne''. The detection in coincidence of the two protons scattered near 0 deg and analysed with the magnetic spectrometer SPES3 allows the reconstruction of missing mass spectra for the η signature. A simulation program which takes into account all the experimental set up characteristics has been realized and tested through the pp → dπ + reaction detected simultaneously with ppppη. The generated proton momentum spectra for ppppη show a pronounced η mass dependence. This characteristic, connected to the kinematical properties of ppppη at threshold, is used to extract the mass of the meson η. The obtained value, m η = 547.65 ± 0.18 MeV, is in good agreement with measurement done recently through the pd → H eη reaction. The total cross section σ t of ppppη measured at 1260, 1265 and 1300 MeV presents a strong energy dependence. This cross section increases less with energy than the phase-space. The influence of p-p and η-p final state interactions in our measurements is studied. Our results are compared with theoretical predictions and assess the dominant character of the baryonic resonance N * (1535) in the η mechanism production at threshold. These experimental results give an energy dependence which is not well reproduced by the theoretical predictions. This discrepancy could be an incorrect description of the η-p interaction in the models. (author). 48 refs., 60 figs., 15 tabs

    Full Text Available The focus of this study is to investigate the capabilities of 3D RVE models in predicting the tensile modulus of carbon nanotube polypropylene (CNT/PP composites which differ slightly in the dispersion, agglomeration and orientation states of CNT within the PP matrix. The composites are made using melt mixing followed by either injection molding or melt spinning of fibers. The dispersion, agglomeration and orientation of CNT within the PP are experimentally altered by using a surfactant and by forcing the molten material to flow through a narrow orifice (melt spinning that promotes alignment of CNT along the flow/drawing direction. An elaborate image analysis technique is used to quantify the CNT characteristics in terms of probability distribution functions (PDF. The PDF are then introduced to the 3D RVE models which also account for the CNT-PP interfacial interactions. It is concluded that the 3D RVE models can accurately distinguish among the different cases (dispersion, distribution, geometry and alignment of CNT as the predicted tensile modulus is in good agreement with the experimentally determined one.

    Motivated by the ongoing discussion concerning the nature of the scalar resonances f0(980) and a0(980), the COSY-11 collaboration has taken exclusive data on the ppppK+K- reaction near the production threshold. A first total cross section σ = (1.80 ± 0.27 -0.35 +0.28 ) nb for the excess energy Q = 17 MeV has been determined. In contrary to the η, ω, and η' single meson production studies which clearly show the strong pp final state interaction (FSI), the cross section values obtained at COSY-11 and DISTO can be both described by a fit with a four-body phase space including the proton-proton final state interaction as well as with one-meson exchange calculations neglecting FSI effects. Therefore, one might think about a compensation of the strong pp interaction through a pK-FSI effect or an additional degree of freedom caused by the four-body final state. In the latter case, strong FSI effects can be expected at Q-values very close to the K+K- production threshold. Such a motivation triggered - in combination with the investigation of the KK-bar interaction being relevant to the structure of the f0 (980) - further measurements at the excess energies Q = 10 and Q 28 MeV at COSY-11

    The ALICE experiment at the LHC has measured a variety of (anti-)(hyper-)nuclei produced in Pb-Pb collisions at = 5.02 TeV and at 2.76 TeV. In addition, a large sample of high quality data was collected in pp collisions at √s = 7 TeV and 13 TeV and in p-Pb collisions at = 5.02 TeV. These data are used to study the production of different (anti-)(hyper-)nuclei in the collisions, namely (anti-)deuteron, (anti-)3He, (anti-)alpha and (anti-)3ΛH. The identification of these (anti-)(hyper-)nuclei is based on the energy loss measurement in the Time Projection Chamber and the velocity measurement in the Time-Of-Flight detector. In addition, the Inner Tracking System is used to distinguish secondary vertices originating from weak decays from the primary vertex. New results on deuteron production as a function of multiplicity in pp, p-Pb and Pb-Pb collisions will be presented, as well as the measurement of 3He in p-Pb and Pb- Pb collisions. Special emphasis will be given to the new results of the (anti-)3ΛH in its charged-two-body decay mode. The large variety of measurements at different energies and system sizes constrains the production models of light flavour baryon clusters, in particular those based on coalescence and the statistical hadronisation approaches.

    The reaction np→ppπ - has been studied in a kinematically complete measurement with a large acceptance time-of-flight spectrometer for incident neutron energies between threshold and 570 MeV. The proton-proton invariant mass distributions show a strong enhancement due to the pp( 1 S 0 ) final state interaction. A large anisotropy was found in the pion angular distributions in contrast to the reaction pp→ppπ 0 . At small energies, a large forward/backward asymmetry has been observed. From the measured integrated cross section σ(np→ppπ - ), the isoscalar cross section σ 01 has been extracted. Its energy dependence indicates that mainly partial waves with Sp final states contribute. (orig.)

    The authors had two major runs of this experiment in the past year: one in October 1983 with a 17 liter liquid hydrogen target, another in June 1984 with liquid deuterium in the target vessel. Both runs were successful and the authors anticipate an accuracy of 2 x 10 -7 in the asymmetry parameter for anti p-p and anti p-d scattering at 800 MeV. The final analysis of both experiments is expected to be completed before January 1985. The experimental apparatus has been disassembled and the authors do not intend to repeat this experiment in the future

    We find a new Penrose limit of AdS 5 xS 5 that gives the maximally symmetric pp-wave background of type-IIB string theory in a coordinate system that has a manifest space-like isometry. This induces a new pp-wave/gauge-theory duality which on the gauge theory side involves a novel scaling limit of N=4 SYM theory. The new Penrose limit, when applied to AdS 5 xS 5 /Z M , yields a pp-wave with a space-like circle. The dual gauge theory description involves a triple scaling limit of an N=2 quiver gauge theory. We present in detail the map between gauge theory operators and string theory states including winding states, and verify agreement between the energy eigenvalues obtained from string theory and those computed in gauge theory, at least to one-loop order in the planar limit. We furthermore consider other related new Penrose limits and explain how these limits can be understood as part of a more general framework. (author)

    The effect of intravenous infusion of synthetic human pancreatic polypeptide (HPP) or a rabbit anti-PP serum on pancreatic exocrine secretion was studied in 10 dogs with gastric and Thomas duodenal cannulas. The infusion of HPP, achieved a plasma PP concentration that mimicked the peak plasma concentration of PP in both interdigestive and postprandial states. This dose of HPP significantly inhibited pancreatic secretion in the interdigestive state. By contrast, immunoneutralization of circulating PP by a rabbit anti-PP serum resulted in significant increases in both interdigestive and postprandial pancreatic secretion, including water, bicarbonate, and protein. The increase in the pancreatic secretion paralleled a decrease in circulating PP level, which lasted for as long as 5 days. Furthermore, the anti-PP serum blocked the inhibitory action of exogenous HPP on pancreatic exocrine secretion. The present study indicates that endogenous PP plays a significant role in the regulation of the pancreatic exocrine secretion in both interdigestive and digestive states. Thus the authors conclude that PP is another hormone regulating pancreatic exocrine secretion in dogs

    The top quark decays before it hadronises. Before its spin state can be changed in a process of strong interaction, it is directly transferred to the top quark decay products. The top quark spin can be deduced by studying angular distributions of the decay products. The Standard Model predicts the top/anti-top quark (t anti t) pairs to have correlated spins. The degree is sensitive to the spin and the production mechanisms of the top quark. Measuring the spin correlation allows to test the predictions. New physics effects can be reflected in deviations from the prediction. In this thesis the spin correlation of t anti t pairs, produced at a centre-of-mass energy of √(s)=7 TeV and reconstructed with the ATLAS detector, is measured. The dataset corresponds to an integrated luminosity of 4.6 fb -1 . t anti t pairs are reconstructed in the l+jets channel using a kinematic likelihood fit offering the identification of light up- and down-type quarks from the t→bW→bq anti q' decay. The spin correlation is measured via the distribution of the azimuthal angle Δφ between two top quark spin analyzers in the laboratory frame. It is expressed as the degree of t anti t spin correlation predicted by the Standard Model, f SM . The results of f SM (Δφ(charged lepton,down-type quark))=1.53±0.14(stat.)±0.32(syst.), f SM (Δφ(charged lepton,b-quark))=0.53±0.18(stat.)±0.49(syst.), f SM (Δφ(combined))=1.12±0.11(stat.)±0.22(syst.), are consistent with the Standard Model prediction of f SM =1.0.

    A high-statistics search for the production of narrow p anti p states with a anti p beam at 5 GeV/c finds no evidence for such states from threshold up to 2.3 GeV. In particular, we set an upper limit (95% C.L.) of 9 nb for any state below 1.95 GeV with GAMMA less than or equal to 5 MeV in the reaction p anti → p anti p π 0

    Using the mass formulas which correctly predict the mass of mesons and baryons the mass of diquark states is computed. From this mass spectrum the existance of the observed narrow baryonia and wide baryonia can be naturally understood. Other relatively narrow Q 2 anti Q 2 states are predicted to exist. (orig.) [de

    We report the first observation of diffractively produced open charm in 800-GeV/c pp collisions of the type pp-->pD*X. We measure cross sections of σdiff(D*+) = (0.185+/-0.044+/-0.054) μb and σdiff(D*-) = (0.174+/-0.034+/-0.029) μb. Our measurements are based on 4.3×109 events recorded by FNAL E690 in the fixed-target run of 1991. We compare our results with previous fixed-target charm experiments.

    Three-body B+ → ppK+ and B(+) → ppπ(+) decays are studied using a data sample corresponding to an integrated luminosity of 3.0 fb(-1) collected by the LHCb experiment in proton-proton collisions at center-of-mass energies of 7 and 8 TeV. Evidence of CP violation in the B(+) → ppK(+) decay is found in regions of the phase space, representing the first measurement of this kind for a final state containing baryons. Measurements of the forward-backward asymmetry of the light meson in the pp rest frame yield A(FB)(ppK(+),m(pp)m(pp) <2.85 GeV/c(2)) = -0.409 ± 0.033 (stat) ± 0.006 (syst). In addition, the branching fraction of the decay B(+) → Λ(1520)p is measured to be B(B(+) → Λ(1520)p) = (3.15 ± 0.48 (stat) ± 0.07 (syst) ± 0.26 (BF)) × 10(-7), where BF denotes the uncertainty on secondary branching fractions.

  14. The measurement of antiproton-proton total cross sections and small-angle elastic scattering at low momentum

    International Nuclear Information System (INIS)

    Linssen, L.H.A.J.

    1986-01-01

    In this thesis two low-momentum antiproton-proton (anti pp) experiments are described. The first one is a set of 24 high statistics anti pp total cross section measurements as a function of the incoming antiproton momentum between p=388 MeV/c and p=599 MeV/c. These measurements simultaneously yield the charge exchange cross section (anti ppanti nn). The second one comprises two high statistics anti pp small-angle elastic scattering measurements at p=233 MeV/c and p=272 MeV/c. The measurements were carried out using the high quality antiproton beam extracted from the Low Energy Antiproton Ring (LEAR) at CERN. The physics motivation for these experiments is a search for anti pp resonances or bound states on one hand, and a detailed study of the anti pp interaction on the other hand. (orig.)

    Normalised differential top-quark-pair production cross sections are measured in pp collisions at a centre-of-mass energy of 7 TeVat the LHC with the CMS detector using data recorded in 2011 corresponding to an integrated luminosity of 5.0 fb -1 . The measurements are performed in the lepton+jets decay channels (e+jets and μ+jets) and the dilepton decay channels (e + e - , μ + μ - , and μ ± e -+ ). The t anti t differential cross section is measured as a function of kinematic properties of the final-state charged leptons and jets associated to b quarks, as well as those of the top quarks and the t anti t system. The data are compared with several predictions from perturbative QCD calculations up to approximate next-to-next-to-leading-order precision. No significant deviations from the standard model are observed. (orig.)

    New data on the production of hyperons, as well as of pions, charged kaons, protons, anti-protons, neutrons in p+p interactions are presented. The data come from a sample of 8.2 million inelastic events obtained with the NA49 detector at the CERN SPS at 158 GeV/c beam momentum. The high statistics data sample allows the extraction of detailed differential distributions as a function of x f , y and p T . The results are compared with published data and models. Moreover, the measurements provide an important reference for studying effects of cold nuclear matter in proton-nucleus and hot dense matter in nucleus-nucleus collisions. (author)

    Two proteins, designated as PP12 and PP14 were originally isolated from soluble extracts of the human placenta and its adjacent membranes. We have shown that they are synthesized by decidualized/secretory endometrium and not by placenta. Both proteins occur at high concentrations in human amniotic fluid, which is therefore an excellent source for purification. PP12 is a 34-kDa glycoprotein, which has an N-terminal amino acid sequence of Ala-Pro-Trp-Gln-Cys-Ala-Pro-Cys-Ser-Ala. This is identical with that of somatomedin-binding protein purified from the amniotic fluid. PP12 too binds somatomedin-C, or IGF-I (insulin-like growth factor-I). Human secretory endometrium synthesizes and secretes PP12, and progesterone stimulates its secretion. PP14 is a 28-kDa glycoprotein. Its N-terminal sequence shows homology to that of beta-lactoglobulins from various species. We have found PP14 in the human endometrium, serum and milk. Immunologically, PP14 is related to progestagen-associated endometrial protein (PEP), alpha-2 pregnancy-associated endometrial protein (alpha-2, PEG), endometrial protein 15 (EP15), alpha-uterine protein (AUP) and chorionic alpha-2 microglobulin (CAG-2). In ovulatory menstrual cycles, the concentration of PP14 increases in endometrial tissue as the secretory changes advance. In serum, the PP14 concentration begins to rise later than the progesterone levels, and high serum PP14 levels are maintained for the first days of the next cycle. By contrast, no elevation of serum PP14 level is seen in anovulatory cycles. Our results show that progesterone-associated proteins are synthesized by the human endometrium and appear in the peripheral circulation, where they can be quantitatively measured using immunochemical techniques.

    Measuring nucleon-nucleon short range correlations (SRCs) has been a goal of the nuclear physics community for many years. They are an important part of the nuclear wave function, accounting for almost all of the high-momentum strength. They are closely related to the EMC effect. While their overall probability has been measured, measuring their momentum distributions is more difficult. In order to determine the best configuration for studying SRC momentum distributions, we measured the 3He(e,e'pp)n reaction, looking at events with high-momentum protons (pp>0.35 GeV/c) and a low-momentum neutron (pn<0.2 GeV/c). We examined two angular configurations: either both protons emitted forward or one proton emitted forward and one backward (with respect to the momentum transfer, q⃗). The measured relative momentum distribution of the events with one forward and one backward proton was much closer to the calculated initial-state pp relative momentum distribution, indicating that this is the preferred configuration for measuring SRC.

  19. Could we understand the 1 D2 → pp-bar charmonium decay?

    International Nuclear Information System (INIS)

    Anselmino, M.; Negrao, M.R.

    1994-01-01

    Massless perturbative QCD forbids, at leading order, the exclusive annihilation of proton-antiproton into charmonium states, which, however, have been observed in the pp-bar channel, indicating the significance of higher order and non perturbative effects in the few GeV energy region. The most well known cases are those of the 1 S 0 (η c ) and the 1P 1 . We consider here the 1 D 2 state, whose coupling to pp-bar in equally forbidden in p QCD, and study several possible non perturbative contributions. It turns out that the observation of the pp-bar → 1 D 2 process would be very intriguing indeed. (author)

We argue that the peculiar resonance-like structures of R(e/sup +/e/sup -/ ..-->.. hadrons) for ..sqrt..s = 6 to 7 GeV may be due to production of the P-wave (cc)-(anti canti c) states. They are predicted to lie in the range 6.4 to 6.8 GeV and mainly decay into charmed mesons.

    We study the correlations of D mesons produced in p+p and p+Pb collisions. These are found to be sensitive to the effects of the cold nuclear medium and the transverse momentum (p{sub T}) regions we are looking into. In order to put this on a quantitative footing, as a first step we analyse the azimuthal correlations of D meson-charged hadron (Dh), and then predict the same for D meson-anti D meson (D anti D) pairs in p+p and p+Pb collisions with strong coupling at leading order O(α{sub s}{sup 2}) and next-to-leading order O(α{sub s}{sup 3}), which includes space-time evolution (in both systems) as well as cold nuclear matter effects (in p+Pb). This also sets the stage and baseline for the identification and study of medium modification of azimuthal correlations in relativistic collision of heavy nuclei at the Large Hadron Collider.

    This paper presents a measurement of the polarisation of W bosons from t anti t decays, reconstructed in events with one high-p{sub T} lepton and at least four jets. Data from pp collisions at the LHC were collected at √(s) = 8 TeV and correspond to an integrated luminosity of 20.2 fb{sup -1}. The angle θ* between the b-quark from the top quark decay and a direct W boson decay product in the W boson rest frame is sensitive to the W boson polarisation. Two different W decay products are used as polarisation analysers: the charged lepton and the down-type quark for the leptonically and hadronically decaying W boson, respectively. The most precise measurement of the W boson polarisation via the distribution of cosθ* is obtained using the leptonic analyser and events in which at least two of the jets are tagged as b-quark jets. The fitted fractions of longitudinal, left- and right-handed polarisation states are F{sub 0} = 0.709 ± 0.019, F{sub L} = 0.299 ± 0.015 and F{sub R} = -0.008 ± 0.014, and are the most precisely measured W boson polarisation fractions to date. Limits on anomalous couplings of the Wtb vertex are set. (orig.)

    Some theoretical ideas about the meson spectrum are reviewed and lessons which may be learned about it in PP-bar annihilation are considered. Experimental questions which, if answered, would have the largest impact on the present understanding of quark and gluon interactions are noted. Conventional qq-bar mesons as treated in potential models, concentrating on the familiar cc-bar systems, are reviewed. The exciting possibility is discussed of detecting constituent gluons in PP-bar annihilations, in gg states - which may already have been detected in e + e - and PP-bar, as will be seen and in the exotic Jsup(PC) 'hermaphrodite' states qq-bar, for which there is currently no experimental evidence.

  7. Universitality features in (pp), (e+e-), and deep inelastic scattering process

    1985-01-01

    This paper discusses the use of the correct variables in (pp), (e + e - ), and deep-inelastic scattering (DIS) processes which allow universality features to be established different ways of producing mulihadronic states. The experimental data where (pp) interactions are compared with (e + e - ) are shown. Extrapolations of collider physics are discussed and it is found that the leading effects must be subtracted and the correct variables have to be used if one wants to compare purely hadronic interactions with (e + e - ) and DIS. The new method of studying (pp) and (pp) collisions allows one to put on equal footing the multiparticle systems that are produced in purely hadronic interactions, in (e + e - ) annihilation, and in DIS processes

    We study the scattering produced by a one dimensional hyperbolic step potential, which is exactly solvable and shows an unusual interest because of its asymmetric character. The analytic continuation of the scattering matrix in the momentum representation has a branch cut and an infinite number of simple poles on the negative imaginary axis which are related with the so called anti-bound states. This model does not show resonances. Using the wave functions of the anti-bound states, we obtain supersymmetric (SUSY) partners which are the series of Rosen–Morse II potentials. We have computed the Wigner reflection and transmission time delays for the hyperbolic step and such SUSY partners. Our results show that the more bound states a partner Hamiltonian has the smaller is the time delay. We also have evaluated time delays for the hyperbolic step potential in the classical case and have obtained striking similitudes with the quantum case. - Highlights: • The scattering matrix of hyperbolic step potential is studied. • The scattering matrix has a branch cut and an infinite number of poles. • The poles are associated to anti-bound states. • Susy partners using antibound states are computed. • Wigner time delays for the hyperbolic step and partner potentials are compared.

    2009-01-01

    The influence of the modification of the free vacuum on the quantum Zeno and anti-Zeno effects, as well as the Lamb (energy) shift of a multilevel atom, is studied. A unitary transformation method has been used to include the counter-rotating terms and to obtain the ground state of the whole Hamiltonian. The anti-Zeno effect is recovered if the modified density of states (DOS) has a dip near the transition frequency. The modification of DOS by a dip or a peak will change the Lamb shift compared with that in the free vacuum. Together with our unitary transformation method, there are three different methods to obtain the change in the Lamb shift. Using our method we investigate the change in the Lamb shift and obtain a formula for the change, which is the same as obtained with the method of Louisell [Quantum Statistical Properties of Radiation (Wiley, New York, 1973)] but different from the method of Cohen-Tannoudji et al. [Atom-Photon Interactions: Basic Processes and Applications (Wiley, New York, 1992), pp. 317 and 417]. The correctness of the Lamb shift formulas obtained by the three methods can be easily testified experimentally.

    A study of low momentum antiproton-proton interactions in the momentum range 0.7 to 2.4 GeV/c has yielded differential cross sections for the elastic channel. An observation of one property of the data when compared with pp elastic scattering within the framework of quark- parton models is presented. The pp and pp systems, related by crossing symmetry, provided significant constraints on any particular model. (13 refs).

    We construct self/anti-self charge conjugate (Majorana-like) states for the (1/2,0)⊕(0,1/2) representation of the Lorentz group, and their analogs for higher spins within the quantum field theory. The problem of the basis rotations and that of the selection of phases in the Dirac-like and Majorana-like field operators are considered. The discrete symmetries properties (P, C, T) are studied. Particular attention has been paid to the question of (anti)commutation of the Charge conjugation operator and the Parity in the helicity basis. Dynamical equations have also been presented. In the (1/2,0)⊕(0,1/2) representation they obey the Dirac-like equation with eight components, which has been first introduced by Markov. Thus, the Fock space for corresponding quantum fields is doubled (as shown by Ziino). The chirality and the helicity (two concepts which are frequently confused in the literature) for Dirac and Majorana states have been discussed

    We discuss the prospects for probing Generalized Parton Distributions (GPDs) via exclusive production of a high-mass system (H = heavy quarkonium, di-photon, di-jet, Higgs boson) in diffractive pp scattering, pp -> p + H + p. In such processes the interplay of hard and soft interactions gives rise to a diffraction pattern in the final-state proton transverse momenta, which is sensitive to the transverse spatial distribution of partons in the colliding protons. We comment on the plans for diffractive pp measurements at RHIC and LHC. Such studies could complement future measurements of GPDs in hard exclusive ep scattering (JLab, COMPASS, EIC)

    Marchewka, M.; Sheregii, E. M.; Tralle, I.; Tomaka, G.; Ploch, D.

    We have studied the parallel magneto-transport in DQW-structures of two different potential shapes: quasi-rectangular and quasi-triangular. The quantum beats effect was observed in Shubnikov-de Haas (SdH) oscillations for both types of the DQW structures in perpendicular magnetic filed arrangement. We developed a special scheme for the Landau levels energies calculation by means of which we carried out the necessary simulations of beating effect. In order to obtain the agreement between our experimental data and the results of simulations, we introduced two different quasi-Fermi levels which characterize symmetric and anti-symmetric states in DQWs. The existence of two different quasi Fermi-Levels simply means, that one can treat two sub-systems (charge carriers characterized by symmetric and anti-symmetric wave functions) as weakly interacting and having their own rate of establishing the equilibrium state.

    High energy elastic pp differential cross section at LHC at the c.m. energy 14 TeV is predicted using the asymptotic behavior of sigma-tot(s) and rho(s), and the measured pbar-p differential cross section at sqrt{s}=546 GeV. The phenomenological investigation has progressively led to an effective field theory model that describes the nucleon as a chiral bag embedded in a quark-antiquark condensed ground state. The measurement of pp elastic scattering at LHC up to large |t| >~ 10 GeV^2 by the TOTEM group will be crucial to test this structure of the nucleon.

    The production of pigments as secondary metabolites by microbes is known to vary by species and by physiological conditions within a single strain. The fungus strain Penicillium purpurogenum IAM15392 has been found to produce violet pigment (PP-V) and orange pigment (PP-O),Monascus azaphilone pigment homologues, when grown under specific culture conditions. In this study, we analysed PP-V and PP-O production capability in seven strains of P. purpurogenum in addition to strain IAM15392 under specific culture conditions. The pigment production pattern of five strains cultivated in PP-V production medium was similar to that of strain IAM15392, and all violet pigments produced by these five strains were confirmed to be PP-V. Strains that did not produce pigment were also identified. In addition, two strains cultivated in PP-O production medium produced a violet pigment identified as PP-V. The ribosomal DNA (rDNA) internal transcribed spacer (ITS) region sequences from the eight P. purpurogenum strains were sequenced and used to construct a neighbor-joining phylogenetic tree. PP-O and PP-V production of P. purpurogenum was shown to be related to phylogenetic placement based on rDNA ITS sequence. Based on these results, two hypotheses for the alteration of pigment production of P. purpurogenum in evolution were proposed. Copyright © 2015 The British Mycological Society.

    Recent results on proton, anti-proton, neutron and charged kaon production in proton-proton and proton, anti-proton, neutron, deuteron and triton production in proton-carbon collisions at 158 GeV/c beam momentum are presented. Data samples of 4.8 million and 385 734 inelastic events in p+p and p+C, respectively, are obtained with the NA49 detector at the CERN SPS accelerator. The charged particles are identified by energy loss measurement in a system of four TPC chambers, while the neutrons are detected in a forward hadronic calorimeter. The data cover a major fraction of the phase space, ranging from 0 to 1.9 GeV in p_T and in Feynman x variable from -0.8 to 0.95 for protons, from -0.2 to 0.3 for anti-protons, from 0.1 to 0.95 for neutrons and from 0 to 0.5 for kaons.

    Full Text Available Problem setting. In today's Ukraine reform encountered not only external but also to internal obstacles. The latter were associated not only with the lack of political will, but also with insufficient theoretical knowledge of individuals who organizes changes. Moreover, getting public office, reformers become a part of the bureaucratic state machinery and experiencing significant resistance change. This primarily occurs because of changes that the organizers do not understand the essence of bureaucracy, and therefore can not overcome its negative features. Recent research and publications analysis. In independent Ukraine the majority of works are devoted to problems of organization of public administration, mainly concentrated around corruption. However, the issue of red tape mostly ignored by the overwhelming majority state researchers. As an exception we can mention common work of V. Tsvetkova and V. Gorbatenko «Democracy – Management – Bureaucracy», in which, inter alia, considered «loss, achievements and prospects of the modernization of Ukrainian society» through the prism of theories of bureaucracy. The reform of the state mechanism have also been the subject of research, both domestic and foreign researchers. Here, in particular, we can recall the work P. Rudyk, A. Yuschyk and joint research experts and World Bank N. Manning and N. Parison and Ukrainian scientists P. Klimushkin and A. Serenok who paid a lot of attention to e-governance as a cornerstone of any factor as modern reforms. Without belittling the achievements of the above scientists should keep in mind that none of them considered reforming the state mechanism in the context of changes in the bureaucracy any other state technology, in particular e-government. Their attention is focused only on the fundamental problems of bureaucracy and e-government. Paper objective. That is why the purpose of this article is the study of e-government as anti-bureaucratic state

    Full text follows: We study the contribution of a finite sum of gluon ladders to the hadronic processes showing that a reliable description is obtained using two order on perturbation theory. The pp(pp-bar) total cross sections are described with good agreement, consistent with unitarity bound. We also calculate the elastic scattering amplitude at non zero momentum transfer t, introducing two distinct Ansatz for the proton impact factor. As a by product the elastic differential cross section is obtained at small t approximation and compared with the data. (author)

    The production of {\\Xi}$^{-}$ and {\\Omega}$^{-}$ baryons and their anti-particles in pp, p-Pb and Pb-Pb collisions has been measured by the ALICE Collaboration. These hyperons are reconstructed via the detection of their charged weak-decay products, which are identified through their measured ionisation losses and momenta in the ALICE Time Projection Chamber. Comparing the production yields in Pb-Pb and pp collisions, a strangeness enhancement has been measured and found to increase with the centrality of the collision and with the strangeness content of the baryon; moreover, in the comparison with similar measurements at lower energies, it decreases as the centre-of-mass energy increases, following the trend already observed moving from SPS to RHIC. Recent measurement of cascade and {\\Omega} in p-Pb interactions are compared with results in Pb-Pb and pp collisions and with predictions from thermal models, based on a grand canonical approach. The nuclear modification factors for the charged {\\Xi} and {\\Omega}...

  5. Feasibility studies of the anti pp→π circle e+e- electromagnetic channel at anti PANDA

    2011-01-01

    Among all possible realizations of quark and antiquark assembly, the nucleon (the proton and the neutron) is the most stable of all hadrons and consequently has been the subject of intensive studies. Mass, shape, radius and more complex representations of its internal structure are measured since several decades using different probes. The proton (spin 1/2) is described by the electric G E and magnetic G M form factors which characterise its internal structure. The simplest way to measure the proton form factors consists in measuring the angular distribution of the electron-proton elastic scattering accessing the so-called Space-Like region where q 2 ≤0. Using the crossed channel anti pp e + e - , one accesses another kinematical region, the so-called Time-Like region where q 2 >0. However, due to the anti pp e + e - threshold q 2 th , only the kinematical domain q 2 >q 2 th > 0 is available. To access the unphysical region, one may use the anti pp→π circle e + e - reaction where the π circle takes away a part of the system energy allowing q 2 to be varied between q 2 th and almost 0. This thesis aims to show the feasibility of such measurements with the anti PANDA detector which will be installed on the new high intensity antiproton ring at the FAIR facility at Darmstadt. To describe the anti pp → π circle e + e - reaction, a Lagrangian based approach is developed. The 5-fold differential cross section is determined and related to linear combinations of hadronic tensors. Under the assumption of one nucleon exchange, the hadronic tensors are expressed in terms of the 2 complex proton electromagnetic form factors. An extraction method which provides an access to the proton electromagnetic form factor ratio R= vertical stroke G E vertical stroke / vertical stroke G M vertical stroke and for the first time in an unpolarized experiment to the cosine of the phase difference is developed. Such measurements have never been performed in the unphysical region up to

    It was determined the mass of the hyperon Λ 0 and of the anti-hyperon anti-Λ 0 , during the second scientific research summer. Both hyperons were collected from inclusive and exclusive proton-proton collisions. The results are in excellent agreement with the universally accepted values. In this paper we compare both values and discuss their theoretical consequences. (Author)

    The measurements described in this report are part of the infiltration experiment carried out at Olkiluoto. The emphasis of these measurements is on obtaining more detailed data on hydraulically significant fractures in the infiltration experiment area. The selected fractures or sections were pumped in turn and flow responses were observed in the other holes by the PFL DIFF-tool. The flow measurements were carried out in drillholes OL-KR14, OL-KR30, OL-PP66, OL-PP67, OL-PP68 and OL-PP69 on the Olkiluoto investigation site between January 2013 and July 2013. Two different flowmeters were used for the measurements. Posiva Flow Log, Difference flow method (PFL DIFF) was used for the determination of hydraulic conductivity and hydraulic head in fractures/fractured zones in the drillholes. PFL DIFF flow logging was conducted in all the drillholes mentioned above. Posiva Flow Log, Transverse flow method (PFL TRANS) was used to determine groundwater flow direction and flow rate across a drillhole. The transverse flow method was used in drillholes OL-KR14 and OL-PP69. PFL DIFF and PFL TRANS measurements had been carried out earlier in drillholes OL-PP66, OL-PP67, OL-PP68 and OL-PP69. The most recent measurements were conducted in 2011. Those measurements were carried out when drillhole OL-KR14 was pumped at packed-off section 13 m - 18 m. Both PFL DIFF and PFL TRANS flowmeters include an electrode for measuring single point resistance (SPR). The device has a high depth resolution and the results were used for depth synchronisation between consecutive DIFF and TRANS measurements. (orig.)

  8. Corporate and state responses to anti-oil protests in the Niger Delta

    Conflicts between oil companies and village communities in the Niger Delta have lasted for several decades, but during the 1990s they escalated further and received international media coverage. Much of it focused on the anti-Shell protests by the Movement for the Survival of the Ogoni People (MOSOP) which led to Shell's withdrawal from the Ogoni area in 1993. Notwithstanding the political changes following General Abacha's death in June 1998, the conflicts are continuing. While the intensity of the Ogoni protests decreased from 1995 onwards, other ethnic and political groups across the Niger Delta began to disrupt oil activities. This article critically examines the response of the Nigerian state and the oil companies to the anti-oil protests in the Delta. The investigation focuses on three generic strategies: concessions by the state and oil companies to protesters, such as the creation of development projects; the use of public relations in dealing with the Niger Delta crisis; and the use of violence by the state and the oil companies against anti-oil protesters. The analysis suggests that the state and corporate response to the Niger Delta crisis has so far been inadequate in the sense that it fails to satisfy the demands of the local people. Judging from past experience, unless there are structural changes within Nigeria's institutional framework, which would allow for a more effective use of the country's oil wealth for the benefit of the oil-producing areas, conflicts in the Niger Delta are likely to continue.

  9. Physiological and Pathological Roles of CaMKII-PP1 Signaling in the Brain

    Full Text Available Ca2+/calmodulin (CaM-dependent protein kinase II (CaMKII, a multifunctional serine (Ser/threonine (Thr protein kinase, regulates diverse activities related to Ca2+-mediated neuronal plasticity in the brain, including synaptic activity and gene expression. Among its regulators, protein phosphatase-1 (PP1, a Ser/Thr phosphatase, appears to be critical in controlling CaMKII-dependent neuronal signaling. In postsynaptic densities (PSDs, CaMKII is required for hippocampal long-term potentiation (LTP, a cellular process correlated with learning and memory. In response to Ca2+ elevation during hippocampal LTP induction, CaMKIIα, an isoform that translocates from the cytosol to PSDs, is activated through autophosphorylation at Thr286, generating autonomous kinase activity and a prolonged Ca2+/CaM-bound state. Moreover, PP1 inhibition enhances Thr286 autophosphorylation of CaMKIIα during LTP induction. By contrast, CaMKII nuclear import is regulated by Ser332 phosphorylation state. CaMKIIδ3, a nuclear isoform, is dephosphorylated at Ser332 by PP1, promoting its nuclear translocation, where it regulates transcription. In this review, we summarize physio-pathological roles of CaMKII/PP1 signaling in neurons. CaMKII and PP1 crosstalk and regulation of gene expression is important for neuronal plasticity as well as survival and/or differentiation.

    Using the polarized proton capability of the Argonne ZGS the authors recently made 90 degrees /sub cm/ measurements of elastic pp scattering from 6 to 11.75 GeV/c, determining the parallel and anti- parallel pure initial spin state cross sections and the associated spin-spin parameter A/sub nn/ with the spins normal to the scattering plane. They find that the parallel to anti-parallel cross section ratio rises dramatically from 1.2+or-.06 at p/sub t//sup 2/=3.3 (GeV /c)/sup 2/ to 3.2+or-.4 at 4.8 (GeV/c)/sup 2/, similar to the p/sub T //sup 2/ dependence previously observed at the fixed laboratory momentum of 11.75 GeV/c. They have also extended the measurements at 6 GeV/c and find that A/sub nn/ has a small but sharp rise at 90 degrees /sub cm/. In addition a month of 12 GeV/c polarized deuteron acceleration in the ZGS enabled them to measure two A/sub nn/ at two points at 6 GeV/c for np elastic scattering: A/sub nn/=-.17+or-.04 at p/sub T//sup 2/=.8, A/sub nn/=-.19+or-.05 at P/sub T//sup 2/=1.0.

    In this work, we study the πJ/ψ and anti D*D invariant mass spectra of the Y(4260) decay to find out the origin of the Z c (3900) and Z c (3885) structures. The πJ/ψ - anti D*D interaction is studied in a coupled-channel quasipotential Bethe-Saltpeter equation approach, and embedded to the Y(4260) decay process to reproduce both π - J/ψ and D *- D 0 invariant mass spectra observed at BESIII simultaneously. It is found out that a virtual state at energy about 3870 MeV is produced from the interaction when both invariant mass spectra are comparable with the experiment. The results support that both Z c (3900) and Z c (3885) have the same origin, that is, a virtual state from πJ/ψ - anti D*D interaction, in which the anti D*D interaction is more important and the coupling between anti D*D and πJ/ψ channels plays a minor role.

    A study of $D^+\\pi^-$, $D^0 \\pi^+$ and $D^{*+}\\pi^-$ final states is performed using pp collision data, corresponding to an integrated luminosity of 1.0 $fb^{-1}$, collected at a centre-of-mass energy of 7 TeV with the LHCb detector. The $D_1(2420)^0$ resonance is observed in the $D^{*+}\\pi^-$ final state and the $D^*_2(2460)$ resonance is observed in the $D^+\\pi^-$, $D^0 \\pi^+$ and $D^{*+}\\pi^-$ final states. For both resonances, their properties and spin-parity assignments are obtained. In addition, two natural parity and two unnatural parity resonances are observed in the mass region between 2500 and 2800 MeV. Further structures in the region around 3000 MeV are observed in all the $D^{*+}\\pi^-$, $D^+\\pi^-$ and $D^0 \\pi^+$ final states.

    Polymeric nano composites are composite materials where an inorganic particle, which has a dimension in the nanometer range, is dispersed in a polymer matrix. Nano composites, using polypropylene (PP) as matrix polymer and titanium dioxide (TiO{sub 2}) as filler, have great versatility in marketing applications, this factor is inherent in the PP and the inherent ability photo degraded TiO{sub 2} particles. This combination can lead to a widely used material and a degradation time after discharge reduced, there by becoming, a residue of low environmental impact. This study aimed to evaluate the dispersion and particle distribution of TiO{sub 2}, non modified, in PP matrix, using the process of preparation by melt extrusion pathway and characterization of the materials obtained: on the molecular dynamics, using low field NMR solid state, measures the relaxation time spin-network (T{sub 1}H); morphology using XRD technique, and thermal analysis technique with the TGA of pure PP and nano composites PP/TiO{sub 2}.

    Baryon-antibaryon production in pp-collisions at 450 GeV/c seen by the CERN-collaboration WA1O2 is discussed in terms of an intermediate non-resonant intermediate ''colorball''. If, in a double peripheral process with particle production in the central region, the exchanges do not carry flavour and anti flavour while the produced particles do, then an intermediate system and the exchanges behave as ''colorballs''. Therefore, if we assume that the exchanges behave as ''colorballs'' which carry those colors and their anticolors which via an intermediate ''colorball'' recombine to two color singlets which hadronize to a baryon-antibaryon pair, a possible and because of its simplicity likely model for baryon-antibaryon production in the central region of high energy pp-reactions appears. If such a ''colorball'', which is assumed to be a system of colors, should be equivalent to a glueball, which is an assumed system of gluons, then a glueball could not be a resonance

  15. PP2A-Mediated Anticancer Therapy

    Full Text Available PP2A is a family of mammalian serine/threonine phosphatases that is involved in the control of many cellular functions including protein synthesis, cellular signaling, cell cycle determination, apoptosis, metabolism, and stress responses through the negative regulation of signaling pathways initiated by protein kinases. Rapid progress is being made in the understanding of PP2A complex and its functions. Emerging studies have correlated changes in PP2A with human diseases, especially cancer. PP2A is comprised of 3 subunits: a catalytic subunit, a scaffolding subunit, and a regulatory subunit. The alternations of the subunits have been shown to be in association with many human malignancies. Therapeutic agents targeting PP2A inhibitors or activating PP2A directly have shed light on the therapy of cancers. This review focuses on PP2A structure, cancer-associated mutations, and the targeting of PP2A-related molecules to restore or reactivate PP2A in anticancer therapy, especially in digestive system cancer therapy.

    Polypropylene (PP)'s low impact strength limits its usages. Adding some a rare earth polymer can enhance PP's tensile strength and impact strength. Acrylic lanthanum was prepared by the reaction between lanthanum oxide and acrylic acid. The IR spectrum prove that and optimum reacting conditions are that the bulk ratio of La(AA) 3 and MMA is not less than one and temperature is about 80 ℃. Lanthanum containing Polymer were added into PP. When percent of addition only was 3%, strength were enhanced 10% , and impact strength 40%. SEM shows the compatibility of rare earth polymer and PP; lanthanum containing polymer can form physical crosslinking between PP's molecules, then every particle's surface connect with several PP molecules and the PP mechanical property were enhanced.

  17. Anti-correlated networks, global signal regression, and the effects of caffeine in resting-state functional MRI.

    Resting-state functional connectivity magnetic resonance imaging is proving to be an essential tool for the characterization of functional networks in the brain. Two of the major networks that have been identified are the default mode network (DMN) and the task positive network (TPN). Although prior work indicates that these two networks are anti-correlated, the findings are controversial because the anti-correlations are often found only after the application of a pre-processing step, known as global signal regression, that can produce artifactual anti-correlations. In this paper, we show that, for subjects studied in an eyes-closed rest state, caffeine can significantly enhance the detection of anti-correlations between the DMN and TPN without the need for global signal regression. In line with these findings, we find that caffeine also leads to widespread decreases in connectivity and global signal amplitude. Using a recently introduced geometric model of global signal effects, we demonstrate that these decreases are consistent with the removal of an additive global signal confound. In contrast to the effects observed in the eyes-closed rest state, caffeine did not lead to significant changes in global functional connectivity in the eyes-open rest state.

    The human cytomegalovirus tegument protein pp71 localizes to the nucleus immediately upon infection, and functions to initiate viral gene expression. Analysis of a series of random insertion mutations revealed that sequences within the mid region (MR) of pp71 are important for localization to the nucleus. Fusion of MR sequences with eGFP revealed that amino acids 94 to 300 were sufficient to target proteins to the nucleus. Random substitution mutagenesis within this domain resulted in two double substitution mutants, pp71P203T/T223M and pp71T228M/L275Q, with a predominantly cytoplasmic localization. Disruption of nuclear targeting resulted in relocalization of the fusion proteins to a distinct perinuclear region. Using tandem mass spectrometry, we determined that threonine 223 can be phosphorylated. Mutation of this residue to a phosphomimetic amino acid resulted in abrogation of nuclear targeting. These results strongly suggest that the intracellular trafficking of pp71 is regulated by phosphorylation

    We report the few hundred second anti-correlated soft lags between soft and hard energy bands in the source GX 339-4 using RXTE observations. In one observation, anti-correlated soft lags were observed using the ISGRI/INTEGRAL hard energy band and the PCA/RXTE soft energy band light curves. The lags were observed when the source was in hard and soft intermediate states, i.e., in a steep power-law state.We found that the temporal and spectral properties were changed during the lag timescale.

    2015-01-01

    The high center-of-mass energies delivered by the LHC during the last three years of operation led to accumulate a significant statistics of light (hyper-)nuclei in pp, p-Pb and Pb-Pb collisions. The ALICE apparatus allows for the detection of these rarely produced particles over a wide momentum range thanks to its excellent vertexing, tracking and particle identification capabilities. The last is based on the specific energy loss in the Time Projection Chamber and the velocity measurement with the Time-Of-Flight detector. The Cherenkov technique, exploited by a small acceptance detector (HMPID), has been also recently used for the most central Pb-Pb collisions to extend the identification range of the (anti-)deuteron at intermediate transverse momentum. An overview of the recent results on the (anti-)deuteron production in pp, p-Pb and Pb-Pb collisions measured with ALICE experiment are presented, giving a particular emphasis to the description of the Cherenkov technique.

    Two-particle angular correlations were measured in pp collisions at √(s) = 7 TeV for pions, kaons, protons, and lambdas, for all particle/anti-particle combinations in the pair. Data for mesons exhibit an expected peak dominated by effects associated with mini-jets and are well reproduced by general purpose Monte Carlo generators. However, for baryon-baryon and anti-baryon-anti-baryon pairs, where both particles have the same baryon number, a near-side anti-correlation structure is observed instead of a peak. This effect is interpreted in the context of baryon production mechanisms in the fragmentation process. It currently presents a challenge to Monte Carlo models and its origin remains an open question. (orig.)

    Full text: A careful analysis of high energies elastic scattering data at 7 TeV for pp, 1800 - 1950 GeV for pp-bar and 540 -541 GeV for pp-bar in terms of its amplitudes has been performed as natural extension of previous analysis for lower energies. The disentanglement of the real and imaginary parts is written consistently with constraints from dispersion relations for amplitudes and for slopes, and also satisfying the universal asymptotic behavior for large |t| values due to the three gluon Exchange process. Values for the imaginary and real slopes and for the total cross section at 7 TeV, 1800-1950 GeV and 540-541 GeV are presented, and the shape of the differential cross section at 14 TeV, with a dip/bump structure more marked and at a smaller values of |t| is predicted. It is predicted that future measurements at large |t| will be connected smoothly with the perturbative tail observed in the interval 5.5 to 14.2 GeV{sup 2} at lower energies and that a marked dip would be observed in pp-bar scattering near this tail range. It is stressed for the consistent description of elastic pp and pp-bar data and pointed out the importance of the future measurements in the Coulomb interference range and in the transition range to the perturbative tail where the perturbative and non-perturbative effects appears together.

    Normalized double-differential cross sections for top quark pair (t anti t) production are measured in pp collisions at a centre-of-mass energy of 8 TeV with the CMS experiment at the LHC. The analyzed data correspond to an integrated luminosity of 19.7 fb{sup -1}. The measurement is performed in the dilepton e{sup ±}μ{sup -+} final state. The t anti t cross section is determined as a function of various pairs of observables characterizing the kinematics of the top quark and t anti t system. The data are compared to calculations using perturbative quantum chromodynamics at next-to-leading and approximate next-to-next-to-leading orders. They are also compared to predictions of Monte Carlo event generators that complement fixed-order computations with parton showers, hadronization, and multiple-parton interactions. Overall agreement is observed with the predictions, which is improved when the latest global sets of proton parton distribution functions are used. The inclusion of the measured t anti t cross sections in a fit of parametrized parton distribution functions is shown to have significant impact on the gluon distribution. (orig.)

  9. Multi-strange baryon production in pp, p–Pb and Pb–Pb collisions measured with ALICE

    2014-01-01

    Full Text Available The production of Ξ− and Ω− baryons and their anti-particles in pp, p–Pb and Pb–Pb collisions has been measured by the ALICE Collaboration. These hyperons are reconstructed via the detection of their charged weak-decay products, which are identified through their measured ionisation losses and momenta in the ALICE Time Projection Chamber. Comparing the production yields in Pb–Pb and pp collisions, a strangeness enhancement has been measured and found to increase with the centrality of the collision and with the strangeness content of the baryon; moreover, in the comparison with similar measurements at lower energies, it decreases as the centre-of-mass energy increases, following the trend already observed moving from SPS to RHIC. Recent measurement of cascade and Ω in p–Pb interactions are compared with results in Pb–Pb and pp collisions and with predictions from thermal models, based on a grand canonical approach. The nuclear modification factors for the charged Ξ and Ω, compared to the ones for the lighter particles, are also presented.

    In this paper, the effect of the compatibilisers-dispersants and other nanofillers on melt spinning of the polypropylene (PP) composites, containing carbon nanotubes (CNTs), and carbon black pigment (CBP) has been investigated. Further, the structure and selected properties of composite fibers, such as mechanical and electrical have been studied. The results revealed, that percolation threshold for PP/CBP composite fibres was situated within the concentration of 15 - 20 wt%, what is several times higher than for PP/CNTs fibers.

    Polymeric nano composites are composite materials where an inorganic particle, which has a dimension in the nanometer range, is dispersed in a polymer matrix. Nano composites, using polypropylene (PP) as matrix polymer and titanium dioxide (TiO 2 ) as filler, have great versatility in marketing applications, this factor is inherent in the PP and the inherent ability photo degraded TiO 2 particles. This combination can lead to a widely used material and a degradation time after discharge reduced, there by becoming, a residue of low environmental impact. This study aimed to evaluate the dispersion and particle distribution of TiO 2 , non modified, in PP matrix, using the process of preparation by melt extrusion pathway and characterization of the materials obtained: on the molecular dynamics, using low field NMR solid state, measures the relaxation time spin-network (T 1 H); morphology using XRD technique, and thermal analysis technique with the TGA of pure PP and nano composites PP/TiO 2 .

    An approach on improvement of the properties of polypropylene / carbon nanotube (PP/CNT) composites is reported. PP blend compositions with carboxylic acid functionalized multi-walled carbon nanotubes (MWCNT-COOH) at filler content 1.0 wt.% were researched. One part of the composites was manufactured by direct thermoplastic mixing PP with the filler, but the other one was made from solution casted masterbatch with the following thermoplastic mixing. An increase of mechanical properties (Young's modulus, storage modulus and tensile strength), compared to an increase of glass transition temperature indicated a reinforcement effect of CNTs on PP matrix, determined from the tensile tests and differential mechanical analysis (DMA), while the elongation was reduced, compared to PP matrix. By differential scanning calorimetry (DSC) analysis, the effect of nanofiller on the reorganization of PP crystallites was observed. A noticeable enhanced effect on increase of the crystallization temperature was indicated for masterbatch manufactured composite. An increase of thermal stability was also observed, compared to pristine PP and the composite made by direct thermoplastic mixing PP with the filler

  15. Hybrid mesons (Q anti Qg) in N anti N annihilation

    International Nuclear Information System (INIS)

    Dover, C.B.; Gutsche, T.; Faessler, A.

    1993-09-01

    N anti N annihilation reactions provide exciting possibilities to study mesonic resonances beyond the usual Q anti Q spectrum. Particularly the search for Q anti Qg mesons containing an explicit dynamical excitation of the gluon field is not promising, since hybrids are predicted to display unique features: exotic quantum numbers (J πC ) and dynamical selection rules for their decay modes. The authors have investigated the possibility of producing hybrids from p anti p atomic states in reactions of the type N anti N(L= 0,1) → π + Q anti Qg. Production rates for hybrid mesons are found to display a strong dependence on the quantum numbers and kinematical factors associated with the transition. The dependence on the orbital angular momentum L of the p anti p atomic state, accessible in p anti p annihilation at rest, would provide a striking signature for the production of hybrids. In estimating branching ratios for the formation of Q anti Qg hybrid mesons in N anti N annihilation reactions at rest, the authors have employed a microscopic model with constituent quarks and gluons in analogy to the annihilation model for the production of Q anti Q mesons

  16. Highly active microbial phosphoantigen induces rapid yet sustained MEK/Erk- and PI-3K/Akt-mediated signal transduction in anti-tumor human gammadelta T-cells.

    Directory of Open Access Journals (Sweden)

    Daniel V Correia

    Full Text Available BACKGROUND: The unique responsiveness of Vgamma9Vdelta2 T-cells, the major gammadelta subset of human peripheral blood, to non-peptidic prenyl pyrophosphate antigens constitutes the basis of current gammadelta T-cell-based cancer immunotherapy strategies. However, the molecular mechanisms responsible for phosphoantigen-mediated activation of human gammadelta T-cells remain unclear. In particular, previous reports have described a very slow kinetics of activation of T-cell receptor (TCR-associated signal transduction pathways by isopentenyl pyrophosphate and bromohydrin pyrophosphate, seemingly incompatible with direct binding of these antigens to the Vgamma9Vdelta2 TCR. Here we have studied the most potent natural phosphoantigen yet identified, (E-4-hydroxy-3-methyl-but-2-enyl pyrophosphate (HMB-PP, produced by Eubacteria and Protozoa, and examined its gammadelta T-cell activation and anti-tumor properties. METHODOLOGY/PRINCIPAL FINDINGS: We have performed a comparative study between HMB-PP and the anti-CD3epsilon monoclonal antibody OKT3, used as a reference inducer of bona fide TCR signaling, and followed multiple cellular and molecular gammadelta T-cell activation events. We show that HMB-PP activates MEK/Erk and PI-3K/Akt pathways as rapidly as OKT3, and induces an almost identical transcriptional profile in Vgamma9(+ T-cells. Moreover, MEK/Erk and PI-3K/Akt activities are indispensable for the cellular effects of HMB-PP, including gammadelta T-cell activation, proliferation and anti-tumor cytotoxicity, which are also abolished upon antibody blockade of the Vgamma9(+ TCR Surprisingly, HMB-PP treatment does not induce down-modulation of surface TCR levels, and thereby sustains gammadelta T-cell activation upon re-stimulation. This ultimately translates in potent human gammadelta T-cell anti-tumor function both in vitro and in vivo upon transplantation of human leukemia cells into lymphopenic mice, CONCLUSIONS/SIGNIFICANCE: The development of

    The first observation of the decay of a B^{0} meson to a purely baryonic final state, B^{0}→pp[over ¯], is reported. The proton-proton collision data sample used was collected with the LHCb experiment at center-of-mass energies of 7 and 8 TeV and corresponds to an integrated luminosity of 3.0  fb^{-1}. The branching fraction is determined to be B(B^{0}→pp[over ¯])=(1.25±0.27±0.18)×10^{-8}, where the first uncertainty is statistical and the second systematic. The decay mode B^{0}→pp[over ¯] is the rarest decay of the B^{0} meson observed to date. The decay B_{s}^{0}→pp[over ¯] is also investigated. No signal is seen and the upper limit B(B_{s}^{0}→pp[over ¯])<1.5×10^{-8} at 90% confidence level is set on the branching fraction.

    We calculate the dominant excitations for the k-level (k element of N) Read-Rezayi (RR) states and their particle-hole conjugates, the anti-Read-Rezayi (RR)-bar, proposed for quantum Hall states. These states are supposed to be built over the second Landau level with total filling factor ν = 2 + ν* with ν* = k/(k + 2) for RR and ν* = 2/(k + 2) for (RR)-bar. In the k-level RR states, based on Z k parafermions, the dominant excitations are the fundamental quasiparticles (qps) with fractional charge e* k = e/(k + 2), with e the electron charge, if k = 2,3. For k = 4 the single-qp and the 2-agglomerate, with charge 2e* k , have the same scaling and both dominate, while for k > 4 the 2-agglomerates are dominant. Anyway the dominance of the 2-agglomerates can be affected by the presence of environmental renormalizations. For all the k-level (RR)-bar states, the single-qp and the 2-agglomerate have the same scaling and both dominate. In this case, only the presence of environmental renormalizations can make one dominant over the other. We determine the conditions in which the environmental renormalizations of the charged and neutral modes make the Abelian 2-agglomerates dominant over the non-Abelian single-qps in the two models and for any value of k. We conclude by observing that, according to these predictions, the dominance of 2-agglomerates, at very low energies for the ν = 5/2, can be an interesting indication supporting the validity of the anti-Pfaffian model in comparison with the Pfaffian.

    The differential cross sections for the production of photons in $\\mathrm{Z} \\to \\mu^+ \\mu^- \\gamma$ decays are presented as a function of the transverse energy of the photon and its separation from the nearest muon. The data for these measurements were collected with the CMS detector and correspond to an integrated luminosity of 4.7 fb$^{-1}$ of pp collisions at $\\sqrt{s}$ = 7 TeV delivered by the CERN LHC. The cross sections are compared to simulations with POWHEG and PYTHIA, where PYTHIA is used to simulate parton showers and final-state photons. These simulations match the data to better than 5%.

  2. Forward diffraction amplitude of pp and pp elastic scattering at accelerator energies

    A simple relation between the total cross section and the forward exponential slope of the elastic differential cross section of pp and pp scattering is indicated. An interpretation of this relation is presented as the formation of a black-disk structure for the elastic diffraction interaction of hadron-hadron scattering at the nonasymptotic energy region

  3. ANTI-CORRELATED SOFT LAGS IN THE INTERMEDIATE STATE OF BLACK HOLE SOURCE GX 339-4

    We report the few hundred second anti-correlated soft lags between soft and hard energy bands in the source GX 339-4 using RXTE observations. In one observation, anti-correlated soft lags were observed using the ISGRI/INTEGRAL hard energy band and the PCA/RXTE soft energy band light curves. The lags were observed when the source was in hard and soft intermediate states, i.e., in a steep power-law state. We found that the temporal and spectral properties were changed during the lag timescale. The anti-correlated soft lags are associated with spectral variability during which the geometry of the accretion disk is changed. The observed temporal and spectral variations are explained using the framework of truncated disk geometry. We found that during the lag timescale, the centroid frequency of quasi-periodic oscillation is decreased, the soft flux is decreased along with an increase in the hard flux, and the power-law index steepens together with a decrease in the disk normalization parameter. We argue that these changes could be explained if we assume that the hot corona condenses and forms a disk in the inner region of the accretion disk. The overall spectral and temporal changes support the truncated geometry of the accretion disk in the steep power-law state or in the intermediate state.

  4. Exploring open-charm decay mode Λ_c anti Λ_c of charmonium-like state Y(4630)

    The newly observed X, Y, Z exotic states are definitely not in the standard Q anti Q"' structures, thus their existence composes a challenge to our understanding on the fundamental principles of hadron physics. Therefore the studies on their decay patterns which are determined by the non-perturbative QCD will definitely shed light on the concerned physics. Generally the four-quark states might be in a molecular state or tetraquark or their mixture. In this work, we adopt the suggestion that Y(4630) is a charmonium-like tetraquark made of a diquark and an anti-diquark. If it is true, its favorable decay mode should be Y(4630) decaying into an open-charm baryon pair, since such a transition occurs via strong interaction and is super-OZI-allowed. In this work, we calculate the decay width of Y(4630) → Λ_c anti Λ_c in the framework of the quark pair creation model. Our numerical results on the partial width computed in the tetraquark configuration coincide with the Belle data within a certain error tolerance. (orig.)

    Porphyrins produced by Propionibacterium acnes represent the principal fluorophore associated with acne, and appear as orange-red luminescence under the Wood's lamp. Assessment of acne based on Wood's lamp (UV) or visible light illumination is limited by photon penetration depth and has limited sensitivity for earlier stage lesions. Inducing fluorescence with near infrared (NIR) excitation may provide an alternative way to assess porphyrin-related skin disorders. We discovered that under 785 nm CW laser excitation PpIX powder exhibits fluorescence emission in the shorter wavelength range of 600-715 nm with an intensity that is linearly dependent on the excitation power. We attribute this shorter wavelength emission to anti-Stokes fluorescence. Similar anti-Stokes fluorescence was also detected focally in all skin-derived samples containing porphyrins. Regular (Stokes) fluorescence was present under UV and visible light excitation on ex vivo nasal skin and sebum from uninflamed acne, but not on nose surface smears or sebum from inflamed acne. Co-registered CW laser-excited anti-Stokes fluorescence and fs laser-excited multi-photon fluorescence images of PpIX powder showed similar features. In the skin samples because of the anti-Stokes effect, the NIR-induced fluorescence was presumably specific for porphyrins since there appeared to be no anti-Stokes emission signals from other typical skin fluorophores such as lipids, keratins and collagen. Anti-Stokes fluorescence under NIR CW excitation is more sensitive and specific for porphyrin detection than UV- or visible light-excited regular fluorescence and fs laser-excited multi-photon fluorescence. This approach also has higher image contrast compared to NIR fs laser-based multi-photon fluorescence imaging. The anti-Stokes fluorescence of porphyrins within sebum could potentially be applied to detecting and targeting acne lesions for treatment via fluorescence image guidance.

  6. Preeclampsia and the Anti-Angiogenic State

    Preeclampsia is a major cause of maternal and fetal morbidity and mortality worldwide, however, its etiology remains unclear. Abnormal placental angiogenesis during pregnancy resulting from high levels of anti-angiogenic factors, soluble Flt1 (sFlt1) and soluble endoglin (sEng), has been implicated in preeclampsia pathogenesis. Accumulating evidence also points to a role for these anti-angiogenic proteins as serum biomarkers for the clinical diagnosis and prediction of preeclampsia. Uncoverin...

    The linearity of the chains confers to iPP, low melt strength, which means a low strength to stretching during elongation. The increase of melt strength and the extensibility is due to the increase of the entanglement of the macromolecules chains. The HMS-PP (high melt strength polypropylene) was synthesized (based on the grains iPP) through gamma irradiation in the iPP under acetylene atmosphere followed by heat treatment for recombination and subsequent annihilation of the other free radicals. Samples of HMS-PP and iPP were subjected to environmental aging in IPEN - Sao Paulo and in the QUV chamber. The results show fractured surfaces of iPP and HMS-PP that are intensified with exposure time. The iPP degradation process has the predominance of chain scissions, with carbonyl and hydroperoxides formation which act as initiators of photo degradation mechanisms. (author)

    proliferant state. Several of our PR measures proved difficult to evaluate and led to some confusion between which are intrinsic and which are extrinsic. A unifying idea affecting several of our measures appears helpful: every nuclear energy system is embedded in a soft system (state owning it and operator running it, inspectors checking it, etc.), which in its turn is placed within a given context (political situation). The overall proliferation resistance comes from the interaction of these layers, and therefore it is not just an intrinsic characteristic of an engineering asset. An example from this point of view, offers a useful clarification: technical difficulty is an intrinsic measure in the sense that no matter which soft system and context we are dealing with, the would-be proliferator will have to make technical modifications to the system to reach his goals. PP Lessons Learned. For theft and sabotage scenarios response time is key, as well as insider cooperation. The methodology and measures were effective in supporting the analysis and generating useful and unambiguous results. PP measures have undergone significant adaptation and revision in earlier applications studies. The paper will describe anticipated improvements to the methodology, resulting from the Case Study. Note: This paper is planned to be part of a series of sessions on PR and PP being organized by Bob Bari. (author)

    Toxocariasis is one of the most important, but neglected, zoonoses, which is mainly caused by Toxocara canis. To better understand the role of serine/threonine protein phosphatase 1 (PP1) in reproductive processes of male adult T. canis, differential expression analysis was used to reveal the profiles of PP1 catalytic subunit α (PP1cα) gene Tc-stp-1 and PP1 regulatory subunit 7 (PP1r7) gene TcM-1309. Indirect fluorescence immunocytochemistry was carried out to determine the subcellular distribution of PP1cα. Double-stranded RNA interference (RNAi) assays were employed to illustrate the function and mechanism of PP1cα in male adult reproduction. Real-time quantitative PCR (qPCR) showed transcriptional consistency of Tc-stp-1 and TcM-1309 in sperm-producing germline tissues and localization research showed cytoplasmic distribution of PP1cα in sf9 cells, which indicated relevant involvements of PP1cα and PP1r7 in spermatogenesis. Moreover, spatiotemporal transcriptional differences of Tc-stp-1 were determined by gene knockdown analysis, which revealed abnormal morphologies and blocked meiotic divisions of spermatocytes by phenotypic aberration scanning, thereby highlighting the crucial involvement of PP1cα in spermatogenesis. These results revealed a PP1cα-PP1r7 mechanism by which PP1 regulates kinetochore-microtubule interactions in spermatogenesis and provided important clues to identify novel drug or vaccine targets for toxocariasis control.

    Full Text Available Flowering is an essential stage of plant growth and development. The successful transition to flowering not only ensures the completion of plant life cycles, it also serves as the basis for the production of economically important seeds and fruits. CONSTANS (CO and FLOWERING LOCUS T (FT are two genes playing critical roles in flowering time control in Arabidopsis. Through homology-based cloning and rapid-amplifications of cDNA ends (RACE, we obtained full-lengths cDNA sequences of Prunus persica CO (PpCO and Prunus persica FT (PpFT from peach (Prunus persica (L. Batsch and investigated their functions in flowering time regulation. PpCO and PpFT showed high homologies to Arabidopsis CO and FT at DNA, mRNA and protein levels. We showed that PpCO and PpFT were nucleus-localized and both showed transcriptional activation activities in yeast cells, consistent with their potential roles as transcription activators. Moreover, we established that the over-expression of PpCO could restore the late flowering phenotype of the Arabidopsis co-2 mutant, and the late flowering defect of the Arabidopsis ft-1 mutant can be rescued by the over-expression of PpFT, suggesting functional conservations of CO and FT genes in peach and Arabidopsis. Our results suggest that PpCO and PpFT are homologous genes of CO and FT in peach and they may function in regulating plant flowering time.

    A detailed study of the associated Standard Model Higgs boson production in 14 TeV pp (LHC) and 2 TeV p(anti p) (Tevatron) collisions, WH with W → lν and ZH with Z → ll, with Higgs boson decays to b(dash b) pair, is presented for Higgs masses of 100 and 120 GeV. Presently, WH with H → b(dash b) production is considered to be less promising than the t(dash t)H associated production for the Higgs searches at LHC. However, studies of Higgs searches at Tevatron indicate that this channel in combination with the WH/ZH channels leading to the E miss T + b(dash b) signature, offers good discovery potential in the mass range 90-140 GeV. The aim of this paper is to provide several details which lead to a quantitative comparison in a consistent framework of the physics potential for these channels in both colliding scenarios. The emphasis is put on the differences in the expected signal and background rates and compositions of the backgrounds. (author)

The same report also defines physical protection (PP) as the use of technical, administrative, and operational measures to prevent the theft of nuclear/radioactive material for the purpose of producing nuclear weapons, producing nuclear devices for nuclear terrorism, or using the facility or transportation system for radiological sabotage. Since the early 1970s right after the Indian nuclear test, the international community has recognized the limits of political and diplomatic means to prevent overt proliferation by states and looked for ways to incorporate technical features that are inherent in NESs. As a first step, active research has been conducted to develop a methodology to evaluate PR and PP components of NESs and has now been reduced to two main R and D streams: the Generation IV International Forum (GIF) and International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO).

    The thermal drillhole device TERO76 (for diameter 76 mm drillholes) used in this study for determining thermal properties of rocks in situ was developed at the Geological Survey of Finland for Posiva in the early 2000's. The measurement method is based on monitoring the temperature variation of a cylindrical heating source in a drillhole. The measured data can be interpreted with full numerical 3D codes as well as with an analytical infinite line source method, a 'rapid interpretation tool', which makes it possible to calculate the first estimates of thermal properties already in the field. Both methods were applied in this study. Because of the unique measurement geometry, only the thermal conductivities can accurately be estimated using the late times of heating periods (accuracy ± 2%). The cylindrical source method cannot directly give the thermal diffusivity or volumetric heat capacity at a sufficient accuracy. Thermal diffusivities are estimated by using the average specific heat capacities and densities of the rock type at the measurement point, or the laboratory results on the general diffusivity-conductivity relationship for different Olkiluoto rock types. The latter technique was applied in this study. Thermal properties were determined in four shallow drillholes (ONK-PP398, ONK-PP399, ONK-PP405, ONK-PP411) located in the ONKALO investigation niche 3 (ONK-TKU-3620) at the access tunnel chainage of 3620 m. The measurement positions (17) were strictly selected on the grounds that approximately an equal number of in situ results would be available in both veined gneiss (VGN) and pegmatitic granite (PGR). The results from the drillholes ONK-PP340 and ONK-PP346 measured in a previous project are also presented in this report. In veined gneiss, the average conductivity determined with numerical model of the present measurements is 3.49 (2.83) Wm -1 K -1 and diffusivity 1.89 x 10 -6 (1.3 10 -6 ) m 2 s -1 .

    The abnormal growth of vascular smooth muscle cells (VSMCs) is considered a critical pathogenic process in inflammatory vascular diseases. We have previously demonstrated that protein phosphatase 2 A (PP2A)-mediated NF-κB dephosphorylation contributes to the anti-inflammatory properties of andrographolide, a novel NF-κB inhibitor. In this study, we investigated whether andrographolide causes apoptosis, and characterized its apoptotic mechanisms in rat VSMCs. Andrographolide activated the p38 mitogen-activated protein kinase (p38MAPK), leading to p53 phosphorylation. Phosphorylated p53 subsequently transactivated the expression of Bax, a pro-apoptotic protein. Transfection with pp2a small interfering RNA (siRNA) suppressed andrographolide-induced p38MAPK activation, p53 phosphorylation, and caspase 3 activation. Andrographolide also activated the Src homology 1 domain-containing protein tyrosine phosphatase (SHP-1), and induced PP2A dephosphorylation, both of which were inhibited by the SHP-1 inhibitor sodium stibogluconate (SSG) or shp-1 siRNA. SSG or shp-1 siRNA prevented andrographolide-induced apoptosis. These results suggest that andrographolide activates the PP2A-p38MAPK-p53-Bax cascade, causing mitochondrial dysfunction and VSMC death through an SHP-1-dependent mechanism.

    Exclusive semileptonic B decays with a D *+ meson in the final state have been studied using the ARGUS detector at the DORIS II storage ring. The branching ratio for the decay anti B 0 →D *+ l - anti ν, where l - is either e - or μ - , has been measured to be (5.2±0.5±0.6)%. A significant rate for the decay anti B→D ** l - anti ν has been observed. From an angular analysis of the cascade anti B 0 →D *+ (→D 0 π + )l - anti ν the forward-backward asymmetry A FB and the D *+ polarization parameter α have been determined to be A FB =0.20±0.08±0.06 and α=1.1±0.4±0.2.

    New data from a 600 000 picture exposure of the BNL 31 inch hydrogen bubble chamber to a separated antiproton beam have been analyzed to try to determine if the π + π - π + π - or π + π - π + π - π 0 final states contribute any broad or narrow structure in the T(2190) region. The resonance channel fractions determined by maximum likelihood fits are all consistent with smooth behavior through the T-region and therefore there is no significant evidence that any of these resonance channels contributes to the broad bump in the total cross section. The errors on some of the fractions, however, limit the sensitivity to approximately 0.5 mb for enhancements in these channels. (Auth.)

    2012-01-01

    Decades of opinion polling and empirical investigations have clearly demonstrated a pervasive anti-atheist prejudice in the United States. However, much of this scholarship relies on two critical and largely unaddressed assumptions: (a) that when people report negative attitudes toward atheists, they do so because they are reacting specifically to their lack of belief in God; and (b) that survey questions asking about attitudes toward atheists as a group yield reliable information about biase...

    A measurement of the inclusive $Z \\to \\tau\\tau$ cross-section in $pp$ collisions at $\\sqrt{s} = 7$ TeV is presented based on a dataset of 1.0 fb$^{-1}$ collected by the LHCb detector. Candidates for $Z \\to \\tau\\tau$ decays are identified through reconstructed final states with two muons, a muon and an electron, a muon and a hadron, or an electron and a hadron. The production cross-section for $Z$ bosons, with invariant mass between 60 and 120 GeV/$c^2$, which decay to $\\tau$ leptons with transverse momenta greater than 20 GeV/$c$ and pseudorapidities between 2.0 and 4.5, is measured to be $\\sigma_{pp \\to Z \\to \\tau\\tau} = 71.4 \\pm 3.5 \\pm 2.8 \\pm 2.5$ pb; the first uncertainty is statistical, the second uncertainty is systematic, and the third is due to the uncertainty on the integrated luminosity. The ratio of the cross-sections for $Z \\to \\tau\\tau$ to $Z \\to \\mu\\mu$ is determined to be $0.93 \\pm 0.09$, where the uncertainty is the combination of statistical, systematic, and luminosity uncertainties of the t...

  1. Chiral power counting and ppppπ0 near threshold

    1995-01-01

    The ppppπ 0 reaction is studied near threshold using power counting arguments based on chiral perturbation theory with an explicit Δ degree of freedom. Important contributions include the so-called impulse term, rescattering via the Δ and rescattering via the (off-shell) seagull term responsible for s-wave pion-nucleon scattering. These contributions largely cancel so that their sum greatly underpredicts the total cross-section. Other mechanisms are also discussed. The inclusion of the previously proposed σ meson exchange mechanism is not sufficient to resolve the discrepancy with experiment

    The E760 Collaboration performed an experiment in the Antiproton Accumulator at Fermilab to study the two photon decay of the η c (1 1 S 0 ) charmonium state formed in bar pp annihilations. This resulted in a new measurement of the mass M ηc =2988.3 -3.1 +3.3 MeV/c 2 and of the product B(η c → bar pp)xΓ(η c →γγ) =(8.1 -2.0 +2.9 ) eV. We performed a search for the process bar pp→η c ' (2 1 S 0 )→γγ over a limited range of center-of-mass energies. Since no signal was observed, we derived upper limits on the product of branching ratios B(η c ' → bar pp)xB(η c ' →γγ) in the center-of-mass energy range 3584≤ √s ≤3624 MeV. We observed no signal for the nonresonant process bar p+p→γ+γ and obtain upper limits

    Low-frequency fluctuations in fMRI signal have been used to map several consistent resting state networks in the brain. Using the posterior cingulate cortex as a seed region, functional connectivity analyses have found not only positive correlations in the default mode network but negative correlations in another resting state network related to attentional processes. The interpretation is that the human brain is intrinsically organized into dynamic, anti-correlated functional networks. Global variations of the BOLD signal are often considered nuisance effects and are commonly removed using a general linear model (GLM) technique. This global signal regression method has been shown to introduce negative activation measures in standard fMRI analyses. The topic of this paper is whether such a correction technique could be the cause of anti-correlated resting state networks in functional connectivity analyses. Here we show that, after global signal regression, correlation values to a seed voxel must sum to a negative value. Simulations also show that small phase differences between regions can lead to spurious negative correlation values. A combination breath holding and visual task demonstrates that the relative phase of global and local signals can affect connectivity measures and that, experimentally, global signal regression leads to bell-shaped correlation value distributions, centred on zero. Finally, analyses of negatively correlated networks in resting state data show that global signal regression is most likely the cause of anti-correlations. These results call into question the interpretation of negatively correlated regions in the brain when using global signal regression as an initial processing step.

    Physalis peruviana L. (PP) is a medicinal herb widely used in folk medicine. In this study, supercritical carbon dioxide (SFE-CO2) method was employed to obtain three different PP extracts, namely SCEPP-0, SCEPP-4 and SCEPP-5. The total flavonoid and phenol concentrations, as well as antioxidant and anti-inflammatory activities of these extracts were analyzed and compared with aqueous and ethanolic PP extracts. Among all the extracts tested, SCEPP-5 demonstrated the highest total flavonoid (234.63+/-9.61 mg/g) and phenol (90.80+/-2.21 mg/g) contents. At concentrations 0.1-30 microg/ml, SCEPP-5 also demonstrated the strongest superoxide anion scavenging activity and xanthine oxidase inhibitory effect. At 30 microg/ml, SCEPP-5 significantly prevented lipopolysaccharide (LPS; 1 microg/ml)-induced cell cytotoxicity in murine macrophage (Raw 264.7) cells. At 10-50 microg/ml, it also significantly inhibited LPS-induced NO release and PGE2 formation in a dose-dependent pattern. SCEPP-5 at 30 microg/ml remarkably blocked the LPS induction of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression. Taken together, these results suggest that SCEPP-5, an extract of SFE-CO2, displayed the strongest antioxidant and anti-inflammatory activities as compared to other extracts. Its protection against LPS-induced inflammation could be through the inhibition of iNOS and COX-2 expression.

    Many repeat proteins contain capping motifs, which serve to shield the hydrophobic core from solvent and maintain structural integrity. While the role of capping motifs in enhancing the stability and structural integrity of repeat proteins is well documented, their contribution to folding cooperativity is not. Here we examined the role of capping motifs in defining the folding cooperativity of the leucine-rich repeat protein, pp32, by monitoring the pressure- and urea-induced unfolding of an N-terminal capping motif (N-cap) deletion mutant, pp32-∆N-cap, and a C-terminal capping motif destabilization mutant pp32-Y131F/D146L, using residue-specific NMR and small-angle X-ray scattering. Destabilization of the C-terminal capping motif resulted in higher cooperativity for the unfolding transition compared to wild-type pp32, as these mutations render the stability of the C-terminus similar to that of the rest of the protein. In contrast, deletion of the N-cap led to strong deviation from two-state unfolding. In both urea- and pressure-induced unfolding, residues in repeats 1-3 of pp32-ΔN-cap lost their native structure first, while the C-terminal half was more stable. The residue-specific free energy changes in all regions of pp32-ΔN-cap were larger in urea compared to high pressure, indicating a less cooperative destabilization by pressure. Moreover, in contrast to complete structural disruption of pp32-ΔN-cap at high urea concentration, its pressure unfolded state remained compact. The contrasting effects of the capping motifs on folding cooperativity arise from the differential local stabilities of pp32, whereas the contrasting effects of pressure and urea on the pp32-ΔN-cap variant arise from their distinct mechanisms of action.

    Small contents of organoclays (1 wt %) were incorporated to PP modified with maleic anhydride by melt intercalation, in order to prepare polymeric films for further applications in food package sector. The films were characterized by X-ray diffraction (XRD) and mechanical properties. The data indicates that the incorporation of organoclay to PP results in transparent films with intercalated morphology and highly. The mechanical properties of nanocomposites films were superior from those pristine films. The results evidences that the PP/PP-g-MA/organoclay nanocomposite films, prepared in this study might be promissory to the food package market and, in short time, be used like a new product by industries of this sector.

    The 2011 dataset of the CMS experiment, consisting of an integrated luminosity of 4.98 inverse femtobarns of pp collisions at sqrt(s) = 7 TeV, enables expanded searches for direct electroweak pair production of charginos and neutralinos in supersymmetric models as well as their analogs in other models of new physics. Searches sensitive to such processes, with decays to final states that contain two or more leptons, are presented. Final states with three leptons, with a same-sign lepton pair, and with an opposite-sign lepton pair in conjunction with two jets, are examined. No excesses above the standard model expectations are observed. The results are used in conjunction with previous results on four-lepton final states to exclude a range of chargino and neutralino masses from approximately 200 to 500 GeV in the context of models that assume large branching fractions of charginos and neutralinos to leptons and vector bosons.

    PP2A is a major tumor suppressor whose inactivation is frequently found in a wide spectrum of human tumors. In particular, deletion or epigenetic silencing of genes encoding the B55 family of PP2A regulatory subunits is a common feature of breast cancer cells. A key player in the regulation of PP2A/B55 phosphatase complexes is the cell cycle kinase MASTL (also known as Greatwall). During cell division, inhibition of PP2A-B55 by MASTL is required to maintain the mitotic state, whereas inactivation of MASTL and PP2A reactivation is required for mitotic exit. Despite its critical role in cell cycle progression in multiple organisms, its relevance as a therapeutic target in human cancer and its dependence of PP2A activity is mostly unknown. Here we show that MASTL overexpression predicts poor survival and shows prognostic value in breast cancer patients. MASTL knockdown or knockout using RNA interference or CRISPR/Cas9 systems impairs proliferation of a subset of breast cancer cells. The proliferative function of MASTL in these tumor cells requires its kinase activity and the presence of PP2A-B55 complexes. By using a new inducible CRISPR/Cas9 system in breast cancer cells, we show that genetic ablation of MASTL displays a significant therapeutic effect in vivo. All together, these data suggest that the PP2A inhibitory kinase MASTL may have both prognostic and therapeutic value in human breast cancer.

    Lignin, a natural macromolecular compound, plays an important role in the texture and taste of fruit. Hard end is a physiological disorder of pear fruit, in which the level of lignification in fruit tissues is dramatically elevated. Cinnamyl alcohol dehydrogenase and expansin genes (PpCAD2 and PpEXP2, respectively) exhibit higher levels of expression in 'Whangkeumbae' (Pyrus pyrifolia) pear fruit exhibiting this physiological disorder, relative to control fruit without symptoms. These genes were isolated from pear fruit and subsequently expressed in tobacco (Nicotiana tabacum) to investigate their function. Histochemical staining for lignin revealed that the degree of lignification in leaf veins and stem tissues increased in plants transformed with sense constructs and decreased in plants transformed with antisense constructs of PpCAD2. The expression of native NtCADs was also inhibited in the antisense PpCAD2 transgenic tobacco. Sense and antisense PpCAD2 transgenic tobacco exhibited an 86.7% increase and a 60% decrease in CAD activity, respectively, accompanied by a complementary response in lignin content in root tissues. The basal portion of the stem in PpEXP2 transgenic tobacco was bent and highly lignified. Additionally, the level of cellulose also increased in the stem of PpEXP2 transgenic tobacco. Collectively, these results suggested that PpCAD2 and PpEXP2 genes play a significant role in lignin accumulation in transgenic tobacco plants, and it is inferred that these two genes may also participate in the increased lignification observed in hard end pear fruit.

    Experiments on low energy antiproton-nucleon are reviewed, especially with respect to S(1935). The complicated problem that S(1935) has been seen in the total and total elastic cross sections but not in the total charge exchange cross section is discussed. The result of the anti pp total cross section measurement done by the Bubble chamber data analysis group of University of Tokyo was reported. It presented a clear evidence of a narrow enhancement at the center-of-mass of 1936 MeV. (author)

    The newly observed X, Y, Z exotic states are definitely not in the standard Q anti Q{sup '} structures, thus their existence composes a challenge to our understanding on the fundamental principles of hadron physics. Therefore the studies on their decay patterns which are determined by the non-perturbative QCD will definitely shed light on the concerned physics. Generally the four-quark states might be in a molecular state or tetraquark or their mixture. In this work, we adopt the suggestion that Y(4630) is a charmonium-like tetraquark made of a diquark and an anti-diquark. If it is true, its favorable decay mode should be Y(4630) decaying into an open-charm baryon pair, since such a transition occurs via strong interaction and is super-OZI-allowed. In this work, we calculate the decay width of Y(4630) → Λ{sub c} anti Λ{sub c} in the framework of the quark pair creation model. Our numerical results on the partial width computed in the tetraquark configuration coincide with the Belle data within a certain error tolerance. (orig.)

    We calculate absorptive corrections to single pion exchange in the production of leading neutrons in pp collisions. Contrary to the usual procedure of convolving the survival probability with the cross section, we apply corrections to the spin amplitudes. The nonflip amplitude turns out to be much more suppressed by absorption than the spin-flip one. We identify the projectile proton Fock state responsible for the absorptive corrections as a color octet-octet 5-quarks configuration. Calculations within two very different models, color-dipole light-cone description, and in hadronic representation, lead to rather similar absorptive corrections. We found a much stronger damping of leading neutrons than in some of previous estimates. Correspondingly, the cross section is considerably smaller than was measured at ISR. However, comparison with recent measurements by the ZEUS collaboration of neutron production in deep-inelastic scattering provides a strong motivation for challenging the normalization of the ISR data. This conjecture is also supported by preliminary data from the NA49 experiment for neutron production in pp collisions at SPS.

  17. Search for Higgs-boson production in association with top-quark pairs in H→b anti b decays at √(s)=8 and 13 TeV with the CMS experiment

    A search of the Higgs boson in association with a top-quark pair is presented, using pp collision data collected by the CMS detector at centre-of-mass energies of 8 and 13 TeV corresponding to integrated luminosities of 19.7 fb -1 and 2.6 fb -1 , respectively. Candidate t anti tH events are selected to enhance the dileptonic decay channel of the t anti t system and the decay of the Higgs boson into two b-quark jets (H→b anti b). The final state of the selected t anti tH(b anti b) processes is characterised by the presence of four b-jets, two originating from the t anti t system and two belonging to the Higgs-boson decay. The b-quark jet pair originating from the t anti t system is identified using multi-variate analysis techniques. In order to reduce the combinatorial background provided by the four b-jets in the final state, a generic method is developed to get an optimal separation between b and anti b jets. The remaining b-jets in the event are used to reconstruct the (m b anti b ) invariant-mass distribution used to estimate the resonant signal above the non-resonant background and to determine the upper-limit on the t anti tH (b anti b) production. A combined fit to the data in two different categories results in an observed (expected) upper limit of μ<10.9(12.0) (for 8 TeV), and μ<13.4(14.4) (for 13 TeV) at the 95 % confidence level, where μ is the ratio of the observed t anti tH production cross section relative to the value expected for a Standard Model Higgs boson with m H =125 GeV.

    We study the energy density and pressure of a relativistic thermal gas of massless fermions on four-dimensional Minkowski and anti-de Sitter space-times using relativistic kinetic theory. The corresponding quantum field theory quantities are given by components of the renormalized expectation value of the stress-energy tensor operator acting on a thermal state. On Minkowski space-time, the renormalized vacuum expectation value of the stress-energy tensor is by definition zero, while on anti-de Sitter space-time the vacuum contribution to this expectation value is in general nonzero. We compare the properties of the vacuum and thermal expectation values of the energy density and pressure for massless fermions and discuss the circumstances in which the thermal contribution dominates over the vacuum one.

    The large number of top quarks produced in proton-proton (pp) collisions at the Large Hadron Collider facilitates precision measurements of top-quark properties that are crucial for testing the consistency of the Standard Model (SM) of particle physics. In particular, differential measurements of the top-quark pair (t anti t) production cross section are essential for comparison with state-of-the-art predictions of Quantum Chromodynamics (QCD) within the SM and for searches for new physics phenomena beyond it. In this thesis, normalised differential t anti t cross sections are measured at a pp centre-of-mass energy of √(s) = 8 TeV. The analysed dataset is recorded by the CMS experiment and corresponds to an integrated luminosity of 19.7 fb -1 . The t anti t production cross section is measured differentially as a function of eighteen kinematic quantities of the top quarks and their decay products. The achieved precision of typically 3-7% allows to distinguish between different QCD predictions for several of the analysed quantities. In particular, the measured t anti t production cross section as a function of the top-quark transverse momentum and its impact on different top-quark related measurements, also outside the scope of this work, is discussed in detail. In addition, the top-quark mass is determined from the normalised differential cross section as a function of the invariant mass of the t anti t system and one additional jet. The obtained result is compatible with other measurements, including the world-average top-quark mass, within the achieved precision of about 1.5%.

    The linearity of the chains confers to iPP, low melt strength, which means a low strength to stretching during elongation. The increase of melt strength and the extensibility is due to the increase of the entanglement of the macromolecules chains. The HMS-PP (high melt strength polypropylene) was synthesized (based on the grains iPP) through gamma irradiation in the iPP under acetylene atmosphere followed by heat treatment for recombination and subsequent annihilation of the other free radicals. Samples of HMS-PP and iPP were subjected to environmental aging in IPEN - Sao Paulo and in the QUV chamber. The results show fractured surfaces of iPP and HMS-PP that are intensified with exposure time. The iPP degradation process has the predominance of chain scissions, with carbonyl and hydroperoxides formation which act as initiators of photo degradation mechanisms. (author)

    In this work, we study the πJ/ψ and anti D*D invariant mass spectra of the Y(4260) decay to find out the origin of the Z{sub c}(3900) and Z{sub c}(3885) structures. The πJ/ψ - anti D*D interaction is studied in a coupled-channel quasipotential Bethe-Saltpeter equation approach, and embedded to the Y(4260) decay process to reproduce both π{sup -}J/ψ and D{sup *-}D{sup 0} invariant mass spectra observed at BESIII simultaneously. It is found out that a virtual state at energy about 3870 MeV is produced from the interaction when both invariant mass spectra are comparable with the experiment. The results support that both Z{sub c}(3900) and Z{sub c}(3885) have the same origin, that is, a virtual state from πJ/ψ - anti D*D interaction, in which the anti D*D interaction is more important and the coupling between anti D*D and πJ/ψ channels plays a minor role.

    Suomen Malmi Oy (Smoy) core drilled eighteen drillholes to survey the ground and bedrock conditions in the encapsulation plant building site at Olkiluoto, Eurajoki 2011. Soil quality, bedrock depth and quality of near surface bedrock were investigated in this project. The drillholes were drilled between 19th of October and 8th of November 2011. The lengths of the drillholes are mostly between 7 to 9 metres, except for the drillhole OL-PP79, which is 15 metres by length. The drillholes are 76 mm by diameter, and the core diameter is 60.2 mm. The lightweight GM75 drilling rig with rubber tracks was used. The drilling water was taken from the ONKALO area research building freshwater pipeline and sodium fluorescein was added as a label agent in the drilling water. The drillholes were not left open. In addition to drilling the drillcores were logged and reported by geologist. Geological logging included the following parameters: lithology, foliation, fracture parameters, fractured zones, core loss, weathering, fracture frequency, RQD and rock quality. The average natural fracture frequencies of the drillcores range from 2.5 pc/m (OL-PP77) to 11.8 pc/m (OL-PP86). The average RQD ranges from 55.1 % (OL-PP86) to 96.4 % (OL-PP77). The penetrated soils are mostly ground fill (blast rock), but some clays and sands are lying below the fill layer. (orig.)

    E. coli can be used as bacterial cell factories for production of biofuels and other useful compounds. The efficient production of the desired products requires careful monitoring of growth conditions and the optimization of metabolic fluxes. To avoid nutrient depletion and maximize product yields we suggest using a natural mechanism for sensing nutrient limitation, related to biosynthesis of an intracellular messenger - guanosine tetraphosphate (ppGpp). We propose a design for a biosensor, which monitors changes in the intracellular concentration of ppGpp by coupling it to a fluorescent output. We used mathematical modelling to analyse the intracellular dynamics of ppGpp, its fluorescent reporter, and cell growth in normal and fatty acid-producing E. coli lines. The model integrates existing mechanisms of ppGpp regulation and predicts the biosensor response to changes in nutrient state. In particular, the model predicts that excessive stimulation of fatty acid production depletes fatty acid intermediates, downregulates growth and increases the levels of ppGpp-related fluorescence. Our analysis demonstrates that the ppGpp sensor can be used for early detection of nutrient limitation during cell growth and for testing productivity of engineered lines.

    Full Text Available Camellia tenuifloria is an indigenous Camellia species used for the production of camellia oil in Taiwan. This study investigated for the first time the potential antioxidant, anti-tyrosinase and anti-inflammatory activities of oil production byproducts, specifically those of the fruit shell, seed shell, and seed pomace from C. tenuifloria. It was found that the crude ethanol extract of the seed shell had the strongest DPPH scavenging and mushroom tyrosinase inhibitory activities, followed by the fruit shell, while seed pomace was the weakest. The IC50 values of crude extracts and fractions on monophenolase were smaller than diphenolase. The phenolic-rich methanol fraction of seed shell (SM reduced nitric oxide (NO production, and inducible nitric oxide synthase (iNOS expression in lipopolysaccharide (LPS-stimulated RAW 264.7 cells. It also repressed the expression of IL-1β, and secretion of prostaglandin E2 (PGE2 and IL-6 in response to LPS. SM strongly stimulated heme oxygenase 1 (HO-1 expression and addition of zinc protoporphyrin (ZnPP, a HO-1 competitive inhibitor, reversed the inhibition of NO production, indicating the involvement of HO-1 in its anti-inflammatory activity. The effects observed in this study provide evidence for the reuse of residues from C. tenuifloria in the food additive, medicine and cosmetic industries.

    Scaled momentum distributions for the strange hadrons K S 0 and Λ/ anti Λ were measured in deep inelastic ep scattering with the ZEUS detector at HERA using an integrated luminosity of 330 pb -1 . The evolution of these distributions with the photon virtuality, Q 2 , was studied in the kinematic region 10 2 2 and 0.001 + e - data alone, fail to describe the measurements. The calculations based on FFs extracted from a global analysis including e + e - , ep and pp data give an improved description. The measurements presented in this paper have the potential to further constrain the FFs of quarks, anti-quarks and gluons yielding K S 0 and Λ/ anti Λ strange hadrons. (orig.)

    Full Text Available Recent results on proton, anti-proton, neutron and charged kaon production in proton-proton and proton, anti-proton, neutron, deuteron and triton production in proton-carbon collisions at 158 GeV/c beam momentum are presented. Data samples of 4.8 million and 385 734 inelastic events in p+p and p+C, respectively, are obtained with the NA49 detector at the CERN SPS accelerator. The charged particles are identified by energy loss measurement in a system of four TPC chambers, while the neutrons are detected in a forward hadronic calorimeter. The data cover a major fraction of the phase space, ranging from 0 to 1.9 GeV in pT and in Feynman x variable from -0.8 to 0.95 for protons, from -0.2 to 0.3 for anti-protons, from 0.1 to 0.95 for neutrons and from 0 to 0.5 for kaons. The comparison of the results on proton and neutron production in p+p interactions and deep inelastic e+p collisions at HERA reveals an independence of target fragmentation on the projectile type. Using the charged kaon data in p+p collisions as a reference, a new evaluation of the energy dependence of kaon production, including neutral kaons, is conducted over a range from 3 GeV to p+p− collider energies. A survey of backward production of protons and pions in p+C collisions in the range of lab angles from 10 to 180 degrees, from 0.2 to 1.2 GeV/c in lab momentum and from 1 to 400 GeV/c in projectile momentum has been performed.

    Chemical interaction and adhesion characteristics between metals (Cu, Ta) and low-k plasma-treated cyclohexane-based plasma polymer (CHexPP) films were studied. In order to generate new functional groups that may contribute to the improvement of adhesion between metal and plasma polymer, we performed O 2 , N 2 , and H 2 /He mixture plasma treatment on the surfaces of CHexPP films. Chemical interactions at the interface between metals (Cu, Ta) and plasma-treated CHexPP films were analyzed by x-ray photoelectron spectroscopy. The effect of plasma treatment and thermal annealing on the adhesion characteristics was measured by a tape test and scratch test. The formation of new binding states on the surface of plasma-treated CHexPP films improved adhesion characteristics between metals and CHexPP films. Thermal annealing improves the adhesion property of Cu/CHexPP films, but degrades the adhesion property of Ta/CHexPP films

    Psidium guajava L. is widely used like food and in folk medicine all around the world. Many studies have demonstrated that guava leaves have anti-hyperglycemic and anti-hyperlipidemic activities, among others, and that these activities belong mainly to phenolic compounds, although it is known that phenolic composition in guava tree varies throughout seasonal changes. Andalusia is one of the regions in Europe where guava is grown, thus, the aim of this work was to study the phenolic compounds present in Andalusian guava leaves at different oxidation states (low, medium, and high). The phenolic compounds in guava leaves were determined by HPLC-DAD-ESI-QTOF-MS. The results obtained by chromatographic analysis reported that guava leaves with low degree of oxidation had a higher content of flavonols, gallic, and ellagic derivatives compared to the other two guava leaf samples. Contrary, high oxidation state guava leaves reported the highest content of cyanidin-glucoside that was 2.6 and 15 times higher than guava leaves with medium and low oxidation state, respectively. The QTOF platform permitted the determination of several phenolic compounds with anti-diabetic properties and provided new information about guava leaf phenolic composition that could be useful for nutraceutical production.

Examples include the collective behavior of the quark-gluon plasma medium, jets, quantum statistics or Coulomb effects, conservation laws, and resonance decays. In this work, measurements of the correlations of identified particles and their antiparticles (for π, K, p, Λ) are reported in pp collisions at √s = 7 TeV at low transverse momenta. The analysis reveals differences in particle production between baryons and mesons. The correlation functions for mesons exhibit the expected peak dominated by the effects of mini-jet fragmentation and are reproduced well by general purpose Monte Carlo generators. For baryon pairs where both particles have the same baryon number, an anti-correlation structure is observed instead of a peak centered at (Δη, Δφ) = (0, 0); an observation which presents a challenge to models typically used to describe pp data (PYTHIA, PHOJET). This baryon anti-correlation is further interpreted in the context of baryon production mechanisms in the fragmentation processes.

    Small contents of organoclays (1 wt %) were incorporated to PP modified with maleic anhydride by melt intercalation, in order to prepare polymeric films for further applications in food package sector. The films were characterized by X-ray diffraction (XRD) and mechanical properties. The data indicates that the incorporation of organoclay to PP results in transparent films with intercalated morphology and highly. The mechanical properties of nanocomposites films were superior from those pristine films. The results evidences that the PP/PP-g-MA/organoclay nanocomposite films, prepared in this study might be promissory to the food package market and, in short time, be used like a new product by industries of this sector.

    This paper presents single lepton and dilepton kinematic distributions measured in dileptonic t anti t events produced in 20.2 fb{sup -1} of √(s) = 8 TeV pp collisions recorded by the ATLAS experiment at the LHC. Both absolute and normalised differential cross-sections are measured, using events with an opposite-charge eμ pair and one or two b-tagged jets. The cross-sections are measured in a fiducial region corresponding to the detector acceptance for leptons, and are compared to the predictions from a variety of Monte Carlo event generators, as well as fixed-order QCD calculations, exploring the sensitivity of the cross-sections to the gluon parton distribution function. Some of the distributions are also sensitive to the top quark pole mass; a combined fit of NLO fixed-order predictions to all the measured distributions yields a top quark mass value of m{sub t}{sup pole} = 173.2 ± 0.9 ± 0.8 ± 1.2 GeV, where the three uncertainties arise from data statistics, experimental systematics, and theoretical sources.

    The aim of this research is to study the relationship between compatibilizer and yield strength of polylactic acid (PLA) and polypropylene (PP) blend. The PLA is blended with PP (PLA/PP) at the ratios of 70/30, 50/50 and 30/70. In addition, (1) polypropylene grafted maleic anhydride (PP-g-MAH) as a compatibilizer at 0.3 and 0.7 part per hundred of PLA/PP resin (phr) and (2) dicumyl peroxide (DCP) being an initiator at 0.03 and 0.07 phr are added in each composition. Yield strength is characterized to study the interaction between compatibilizer, initiator and yield strength by using experimental design of multilevel full factorial. The results show that (1) the yield strength of PLA/PP blend are increased after addition of compatibilizer. Because the adding of PP-g-MAH and DCP resulted in improving compatibility between PLA and PP. (2) there are interaction between PP-g-MAH and DCP that have affected the final properties of PLA/PP blend. The highest yield strength of 27.68 MPa is provided at the ratio of 70/30 blend by using the 0.3 phr of PP-g-MAH and 0.03 phr of DCP. Linear regression model is fitted and follow the assumptions of normal distribution.

    In this work we study the ρB{sup *} anti B{sup *} three-body system solving the Faddeev equations in the fixed center approximation. We assume the B{sup *} anti B{sup *} system forming a cluster, and in terms of the two-body ρB{sup *} unitarized scattering amplitudes in the local hidden gauge approach we find a new I(J{sup PC}) = 1(3{sup -}) state. The mass of the new state corresponds to a two-particle invariant mass of the ρB{sup *} system close to the resonant energy of the *, indicating that the role of this J = 2 resonance is important in the dynamical generation of the new state.

    From the study of the reaction pi /sup -/p to p/sub F/pp pi /sup -/ using a fast proton (p/sub F/) trigger device in the CERN Omega spectrometer, the authors find evidence for two narrow pp states produced mainly in association with a Delta degrees (1232) and a N degrees (1520). The statistical significance of each peak is greater than 6 standard deviations. Masses and natural widths of these resonances are respectively M/sub 1/=2020+or-3 MeV, Gamma /sub 1 /=24+or-12 MeV and M/sub 2/=2204+or-5 MeV, Gamma /sub 2/=16/sub -16 //sup +20/ MeV. The data are consistent with a small production of the narrow approximately 1935 MeV resonance already reported. Production cross sections for these new pp resonances are given. (8 refs).

    an evolutionary selection pressure on cephalopods to develop a mechanism for detecting and evading sound-emitting toothed whale predators. Ultrasonic detection has evolved in some insects to avoid echolocating bats, and it can be hypothesized that cephalopods might have evolved similar ultrasound detection...... as an anti-predation measure. We test this hypothesis in the squid Loligo pealeii in a playback experiment using intense echolocation clicks from two squid-eating toothed whale species. Twelve squid were exposed to clicks at two repetition rates (16 and 125 clicks per second) with received sound pressure...... levels of 199-226dBre1μPa (pp) mimicking the sound exposure from an echolocating toothed whale as it approaches and captures prey. We demonstrate that intense ultrasonic clicks do not elicit any detectable anti-predator behaviour in L. pealeii and that clicks with received levels up to 226dBre1μPa (pp...

    We present strange particle spectra and yields measured atmid-rapidity in sqrt text s=200 GeV proton-proton (p+p) collisions atRHIC. We find that the previously observed universal transverse mass(mathrm mT \\equiv\\sqrt mathrm p_T 2+\\mathrm m2) scaling of hadronproduction in p+p collisions seems to break down at higher \\mt and thatthere is a difference in the shape of the \\mt spectrum between baryonsand mesons. We observe mid-rapidity anti-baryon to baryon ratios nearunity for Lambda and Xi baryons and no dependence of the ratio ontransverse momentum, indicating that our data do not yet reach thequark-jet dominated region. We show the dependence of the mean transversemomentum (\\mpt) on measured charged particle multiplicity and on particlemass and infer that these trends are consistent with gluon-jet dominatedparticle production. The data are compared to previous measurements fromCERN-SPS, ISR and FNAL experiments and to Leading Order (LO) and Next toLeading order (NLO) string fragmentation model predictions. We infer fromthese comparisons that the spectral shapes and particle yields from $p+p$collisions at RHIC energies have large contributions from gluon jetsrather than quark jets.

  4. Generalized parton distributions and rapidity gap survival in exclusive diffractive pp scattering

    We propose a new approach to the problem of rapidity gap survival (RGS) in the production of high-mass systems (H = dijet, heavy quarkonium, Higgs boson) in double-gap exclusive diffractive pp scattering, pp-->p + (gap) + H + (gap) + p. It is based on the idea that hard and soft interactions proceed over widely different time- and distance scales and are thus approximately independent. The high-mass system is produced in a hard scattering process with exchange of two gluons between the protons. Its amplitude is calculable in terms of the gluon generalized parton distributions (GPDs) in the protons, which can be measured in J= production in exclusive ep scattering. The hard scattering process is modified by soft spectator interactions, which we calculate in a model-independent way in terms of the pp elastic scattering amplitude. Contributions from inelastic intermediate states are suppressed. A simple geometric picture of the interplay of hard and soft interactions in diffraction is obtained. The onset of the black-disk limit in pp scattering at TeV energies strongly suppresses diffraction at small impact parameters and is the main factor in determining the RGS probability. Correlations between hard and soft interactions (e.g. due to scattering from the long-range pion field of the proton, or due to possible short-range transverse correlations between partons) further decrease the RGS probability. We also investigate the dependence of the diffractive cross section on the transverse momenta of the final-state protons (''diffraction pattern''). By measuring this dependence one can perform detailed tests of the interplay of hard and soft interactions, and even extract information about the gluon GPD in the proton. Such studies appear to be feasible with the planned forward detectors at the LHC.

  6. Interactions of polyomavirus middle T with the SH2 domains of the pp85 subunit of phosphatidylinositol-3-kinase.

    The binding of phosphatidylinositol-3-kinase to the polyomavirus middle T antigen is facilitated by tyrosine phosphorylation of middle T on residue 315. The pp85 subunit of phosphatidylinositol-3-kinase contains two SH2 domains, one in the middle of the molecule and one at the C terminus. When assayed by blotting with phosphorylated middle T, the more N-terminal SH2 domain is responsible for binding to middle T. When assayed in solution with glutathione S transferase fusions, both SH2s are capable of binding phosphorylated middle T. While both SH2 fusions can compete with intact pp85 for binding to middle T, the C-terminal SH2 is the more efficient of the two. Interaction between pp85 or its SH2 domains and middle T can be blocked by a synthetic peptide comprising the tyrosine phosphorylation sequence around middle T residue 315. Despite the fact that middle T can interact with both SH2s, these domains are not equivalent. Only the C-terminal SH2-middle T interaction was blocked by anti-SH2 antibody; the two SH2 fusions also interact with different cellular proteins. Images PMID:1380095

    Results are presented from a search for heavy bottom-like quarks, pair-produced in pp collisions at sqrt(s) = 7 TeV, undertaken with the CMS experiment at the LHC. The b' quarks are assumed to decay exclusively to tW. The b' anti-b' to t W(+) anti-t W(-) process can be identified by its distinctive signatures of three leptons or two leptons of same charge, and at least one b-quark jet. Using a data sample corresponding to an integrated luminosity of 4.9 inverse femtobarns, observed events are compared to the standard model background predictions, and the existence of b' quarks having masses below 611 GeV/$c^2$ is excluded at 95% confidence level.

    Full Text Available Abstract Background Protein phosphatase one (PP1 is a ubiquitously expressed, highly conserved protein phosphatase that dephosphorylates target protein serine and threonine residues. PP1 is localized to its site of action by interacting with targeting or regulatory proteins, a majority of which contains a primary docking site referred to as the RVXF/W motif. Results We demonstrate that a peptide based on the RVXF/W motif can effectively displace PP1 bound proteins from PP1 retained on the phosphatase affinity matrix microcystin-Sepharose. Subsequent co-immunoprecipitation experiments confirmed that each identified binding protein was either a direct PP1 interactor or was in a complex that contains PP1. Our results have linked PP1 to numerous new nuclear functions and proteins, including Ki-67, Rif-1, topoisomerase IIα, several nuclear helicases, NUP153 and the TRRAP complex. Conclusion This modification of the microcystin-Sepharose technique offers an effective means of purifying novel PP1 regulatory subunits and associated proteins and provides a simple method to uncover a link between PP1 and additional cellular processes.

    Full Text Available Rice husk is a by-product of rice milling process that usually finds inadequate final disposal (burning, land filling. Thermoplastics composites filled with rice husk flour are materials that offer an alternative for using this agricultural resource viewing the production of low dense materials with some specific properties. In this work composites of polypropylene (PP and rice husk flour (RHF were prepared by melt extrusion. Maleic anhydride-modified PP (MAPP was added as a coupling agent. It was verified that tensile strength decreased with filler loading. The presence of MAPP improved this property showing a strong dependence on the MAPP/RHF ratio (MAPP/RHF = 0.03 produced the best results. The density of the composites slightly increased with filler and coupling agent in comparison to pure PP. The presence of MAPP diminished more than 20% water uptake in highly-loaded composites.

    Complete text of publication follows. Electron Spin Resonance (ESR) studies on Polystyrene (PS), Polypropylene (PP) and their mixtures at compositions of 80/20 with and without a compatibilizer (SBS in block), 7.5 wt.%, irradiated with gamma rays from a Cobalt-60 source with a dose rate of 4.8 KGy/h at integral doses of radiation of 10, 25, 50, 60, 70, 400, 800 and 1300 KGy in the presence of air and at room temperature (RT) are reported. The dependence of resonance line width, Hpp; resonance line shapes K, and radical concentration, S, with the integral dose of irradiation is investigated. The nature of the free radicals after ten days of air storage is discussed. The free radical concentration, the double integral of the resonance line, S, has been estimated at room temperature, RT, for a group of single lines, characterized by the same giromagnetic, g, value by direct numerical double integration. In the samples studied no spectrum of 0 kGy of integral dose was observed. The concentration of radicals, S, observed when the integral radiation doses was increased, presents a maximum value in the PP samples at high doses (70-1300 kGy) and minimum values in the PS samples with the same doses. This shows that the PP degrades at a faster rate than the PS, owing to the presence of the bencenic ring in the latter. In the PS/PP mixtures studied with and without compatibilizer, the values of the radical concentration is found between the observed values in the homopolymers, being closer to the PS, which might imply that the presence of PS decays the degradation process of the PP in the mixture

  11. Predictions for the anti B0 → anti K*0 X(YZ) and anti Bs0 → φ X(YZ) with X(4160), Y(3940), Z(3930)

    We investigate the decay of anti B 0 → anti K *0 R and anti B s 0 → φR with R being the X(4160), Y(3940), Z(3930) resonances. Under the assumption that these states are dynamically generated from the vector-vector interaction, as has been concluded from several theoretical studies, we use a reaction mechanism of quark production at the elementary level, followed by hadronization of one final q anti q pair into two vectors and posterior final state interaction of this pair of vector mesons to produce the resonances. With this procedure we are able to predict five ratios for these decays, which are closely linked to the dynamical nature of these states, and also predict the order of magnitude of the branching ratios which we find of the order of 10 -4 , well within the present measurable range. In order to further test the dynamical nature of these resonances we study the anti B s 0 → φ D* anti D* and anti B s 0 → φ D s * anti D s * decays close to the D* anti D* and D s * anti D s * thresholds and make predictions for the ratio of the mass distributions in these decays and the anti B s 0 → φR decay widths. The measurement of these decays rates can help unravel the nature of these resonances. (orig.)

    Understanding mechanisms of (+)-anti-BPDE detoxification is crucial for combating its mutagenic and potent carcinogenic action. However, energetic-structural correlations of reaction intermediates and transition states during detoxification via hydrolysis are poorly understood. To gain mechanistic insight we have computationally characterized intermediate and transition species associated with spontaneous and general-acid catalyzed hydrolysis of (+)-anti-BPDE. We studied the role of cacodylic acid as a proton donor in the rate limiting step. The computed activation energy (ΔG‡) is in agreement with the experimental value for hydrolysis in a sodium cacodylate buffer. Both types of, spontaneous and acid catalyzed, BPDE hydrolysis can proceed through low-entropy hydrogen bonded intermediates prior to formation of transition states whose energies determine reaction activation barriers and rates.

  13. The combinatorial PP1-binding consensus Motif (R/Kx( (0,1V/IxFxx(R/Kx(R/K is a new apoptotic signature.

    Directory of Open Access Journals (Sweden)

    Angélique N Godet

    Full Text Available BACKGROUND: Previous studies established that PP1 is a target for Bcl-2 proteins and an important regulator of apoptosis. The two distinct functional PP1 consensus docking motifs, R/Kx((0,1V/IxF and FxxR/KxR/K, involved in PP1 binding and cell death were previously characterized in the BH1 and BH3 domains of some Bcl-2 proteins. PRINCIPAL FINDINGS: In this study, we demonstrate that DPT-AIF(1, a peptide containing the AIF(562-571 sequence located in a c-terminal domain of AIF, is a new PP1 interacting and cell penetrating molecule. We also showed that DPT-AIF(1 provoked apoptosis in several human cell lines. Furthermore, DPT-APAF(1 a bi-partite cell penetrating peptide containing APAF-1(122-131, a non penetrating sequence from APAF-1 protein, linked to our previously described DPT-sh1 peptide shuttle, is also a PP1-interacting death molecule. Both AIF(562-571 and APAF-1(122-131 sequences contain a common R/Kx((0,1V/IxFxxR/KxR/K motif, shared by several proteins involved in control of cell survival pathways. This motif combines the two distinct PP1c consensus docking motifs initially identified in some Bcl-2 proteins. Interestingly DPT-AIF(2 and DPT-APAF(2 that carry a F to A mutation within this combinatorial motif, no longer exhibited any PP1c binding or apoptotic effects. Moreover the F to A mutation in DPT-AIF(2 also suppressed cell penetration. CONCLUSION: These results indicate that the combinatorial PP1c docking motif R/Kx((0,1V/IxFxxR/KxR/K, deduced from AIF(562-571 and APAF-1(122-131 sequences, is a new PP1c-dependent Apoptotic Signature. This motif is also a new tool for drug design that could be used to characterize potential anti-tumour molecules.

  14. Study on GIF PR/PP evaluation methodology

    Proliferation resistance (PR) and physical protection (PP) is one of the four technology goals of generation IV nuclear energy systems (NESs). The PR component of the goal focuses on providing strong assurance that generation IV NESs are the least desirable sources for the diversion or undeclared production of nuclear materials, whereas the PP portion of the goal ensures that generation IV NESs are robust against theft and sabotage. In 2002, the road map of the Generation IV International Forum (GIF) envisioned that the R and D program for PR and PP would have three areas: 1) safeguards and physical protection technology R and D for each GIF system; 2) formulation of PR and PP criteria and metrics; and 3) evaluation of the criteria and metrics. To cover these R and D items, the PR and PP Working Group (PRPPWG) was formed in late 2002 and has since developed a methodology for PR and PP evaluation. In a succession of revisions beginning in 2004, consensus was achieved amongst all participating GIF countries and related organizations (i.e., IAEA and EU), and Revision 6 of the methodology report was approved by GIF for open distribution in 2011. The paper describes in detail the methodology developed by the PRPPWG and discusses its applicability to the sodium-cooled fast reactor (SFR) fuel cycle with pyro processing currently under development in Korea.

    We study the sensitivity of pion interferometry in bar pp and bar pp collisions at ISR energies to the resonance abundance. We show that those data are not compatible with the full resonance fractions predicted by the Lund model. The preliminary S+S and O+Au data at 200 GeV are, however, not incompatible with the Lund predictions, although their sensitivity to resonances is significantly weaker than in the pp/bar pp case

    Three-dimensional overcoring rock stress measurements were conducted in drillholes ONK-PP169 and ONK-PP170 at the 230 m depth level in the ONKALO site ramp. The measurements were performed during the spring of 2008. The objective of the measurements was to obtain better understanding of the in situ stress field for the measured depth levels. Another objective was to increase the confidence and reliability and to diminish the uncertainties concerning the state of stress at shallow depth of ONKALO. Due to problems with bonding of strain gauges, which may have been caused by a thin layer/coating of unknown material on the pilot hole wall, stress measurements results were only achieved in drillhole ONK-PP170 at -230 m level. The initial plan was to conduct measurements at three depth levels, -120 m, -180 m and -220 m levels, in the ONKALO ramp. Two (2) of the conducted measurements could be rated as successful (rating a) two (2) measurement were partly successful (rating b). The results from the measurements assuming isotropic condition, the major principal stress is plunging between 18deg and 35deg and trending between S and WSW. Stress magnitudes (for σ 1 ) varied between 12 and 16 MPa except for test 2:3:3 where a much higher value (47 MPa) was obtained. The orientation of the major principal stress are similar for test 2:3:3 and 2:4:3 (WSW), but are different from the orientation of the major principal stress for test 2:5:1 and 2:6:1 (S). Likewise, the horizontal stresses have the highest values for test 2:3:3 but in this case the orientation is similar to test 2:5:1 and 2:4:3. The horizontal stress magnitudes of test 2:4:3, 2:5:1 and 2:6:1 are similar but the orientation for test 2:6:1 are different from the other three tests. The results from two of the measurements assuming transversely isotropic conditions, the major principal stress is 12.3 MPa and 12.7 MPa, trending WSW and S, plunging 30 deg. (orig.)

    The isotactic polypropylene is a linear polymer which exhibits low melt strength. Irradiation of PP under inert atmosphere causes a combination of chain scissioning and long-chain branching, and results in a material with significant enhanced melt strength. This process, which is sometimes termed visbreaking, thus provides improvement of rheological properties. HMS-PP (High Melt Strength Polypropylene) was obtained by the irradiation in atmosphere of acetylene as crosslinker agent. It was employed doses of 12.5 and 20 kGy of gamma radiation. The objective of this study is to investigate the effects of thermal ageing on the crystallinity level and chemical structure of HMS-PP. The thermal stability of the HMS-PP was evaluated after thermal ageing of samples using a stove at temperature of 90 deg C, in presence of air at different periods of time. The samples submitted to the thermal ageing were characterized by: thermogravimetry (TGA), differential scanning calorimetry (DSC), infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). Since the long-term engineering properties of HMS-PP are intrinsically linked with the polymer microstructure, there is significant interest in understanding the effects of ageing, particularly due to prolonged exposure at service temperatures. In thermo-oxidative conditions, the formation of the oxidation products essentially involves a hydrogen abstraction by the peroxyl radicals, leading to hydroperoxides as primary products and chemical degradation in the immediate crack tips. Oxidative degradation on the network of HMS-PP, created by radiation process of PP, was revealed by the analytical results showing the susceptibility of HMS-PP to thermal oxidative degradation. Yellowing of the samples surface and oxidative products of degradation among other evidences were observed. (author)

    Measurements of jet activity in top-quark pair events produced in proton-proton collisions are presented, using 3.2 fb{sup -1} of pp collision data at a centre-of-mass energy of 13 TeV collected by the ATLAS experiment at the Large Hadron Collider. Events are chosen by requiring an opposite-charge eμ pair and two b-tagged jets in the final state. The normalised differential cross-sections of top-quark pair production are presented as functions of additional-jet multiplicity and transverse momentum, p{sub T}. The fraction of signal events that do not contain additional jet activity in a given rapidity region, the gap fraction, is measured as a function of the p{sub T} threshold for additional jets, and is also presented for different invariant mass regions of the eμb anti b system. All measurements are corrected for detector effects and presented as particle-level distributions compared to predictions with different theoretical approaches for QCD radiation. While the kinematics of the jets from top-quark decays are described well, the generators show differing levels of agreement with the measurements of observables that depend on the production of additional jets.

    A measurement of the groomed jet mass ($M_g$) normalized by the jet transverse momentum ($p_\\text{T}^\\text{jet}$) for anti-$k_\\text{T}$ jets with the radius parameter $0.4$ in PbPb and pp collisions at a center of mass energy of $5.02\\,\\mathrm{TeV}$ per nucleon pair is presented. The jet grooming algorithm is a recursive procedure which sequentially removes soft constituents of a jet until a pair of hard subjets is found. The results of this grooming can be used to study modifications to partons and their evolution while traversing the hot and dense medium created in heavy ion collisions, via small angle splitting of quarks and gluons insie the jet cores. The CMS detector at the LHC is used to perform this analysis for $p_\\text{T}^\\text{jet}$ between 140 and $300\\,\\mathrm{GeV}$ and pseudo-rapidity less than 1.3 in both PbPb and pp collisions, and for a range of PbPb collision centralities.

    The annihilation frequencies of 19 pp annihilation reactions at rest obtained in different target densities are analysed in order to determine the values of the P-wave annihilation percentage at each target density and the average hadronic branching ratios from P- and S-states. Both the assumptions of linear dependence of the annihilation frequencies on the P-wave annihilation percentage of the protonium state and the approach with the enhancement factors of Batty (1989) are considered. Furthermore the cases of incompatible measurements are discussed. (55 refs).

    The ''ppK{sup -}'' is a well established state in theory and is a candidate for a new kind of hadronic matter formed by antikaons and nucleons. The HADES spectrometer at GSI has probed the existence of such a state by measuring its possible decay products p and Λ. These decay products have been studied specifically in the reaction p+p → p+K{sup +}+Λ at a beam kinetic energy of 3.5 GeV. A partial wave analysis, performed on this final state, helped in describing the event distributions, which is a necessary condition to search for an additional small signal in the statistic. We have found no indication for the production of a kaonic nuclear bound state in our data and have, thus, set an upper limit for its production cross section. Furthermore, did we repeat the analysis of the DISTO collaboration in which a signal like distribution appeared in so-called deviation spectra. We can show that this method is error-prone in terms of the applied selection cuts and is, thus, not reliable in order to make statements about the ''ppK{sup -}''.

    The human being is daily exposed to free radicals or reactive oxygen species (Ros), as a result of the breathing and the interactions with xenobiotics that can cause irreversible lesions in molecules and cellular structures and that they are associated to diseases like the cancer, neuro degenerative and to the acceleration of the normal process of aging. Fortunately, to reduce the damaging effect of the Ros the cell has endogenous antioxidant systems constituted by antioxidant enzymes as: the superoxide dismutase (Sod), the catalase (Cat), and the glutathione peroxidase and reductase. Even, when these systems are not enough, we find to the exogenous antioxidants that cooperate in the balance of the Ros, as the porphyrins that include to the chlorophyllin, the hemin and the bilirubin among others. The protoporphyrin-Ix (Pp-Ix) is a tetra pyrrole without metallic center with antimutagenic and antioxidant activity similar to that of the chlorophyllin. However, is also known that their over-expression has toxic effects, because induces Ros. In Drosophila melanogaster, recently was found that the Pp-Ix have dual action anti and persistent mutagenic. One of their possible mechanism to act like mutagen is through the Ros induction. To evaluate this possibility and based in that the increase in the Ros levels can accelerate the aging process, in the present work the Pp-Ix role was evaluated, in the life period of Drosophila melanogaster strains deficient in Sod and Cat, sensitive to radiation or oxidative stress (rad, whd and flr{sup 3}) and a wild one as control (C-S). Females and males of each strain were treated chronically for separate with sucrose or Pp-Ix and every 15 days a group of each sex was irradiated with 10 Gy of gamma rays. The results indicated that the chronic treatment with Pp-Ix and in combination with radiation, increased the life period of the C-S strain. The Sod strain had a contrary effect and this effect was pronounced with the combined treatment of

    Inclusive experiments pp → π + +..., Σp → Λ +..., pp → K + +... are proposed in which it is possible to come very close to the π, K, N, Λ poles. In these experiments it is possible, in principle, to extract the most precise values of the coupling constants KNY, Σ π Λ,... and to state the problem which is the nature of the exchanges. A critical analysis of the pp → π + + ... data is carried out

    Full Text Available Transverse momentum (pT and rapidity (y spectra of Z bosons and quarkonium states (some charmonium cc¯ mesons such as J/ψ and ψ(2S and some bottomonium bb¯ mesons such as Υ(1S, Υ(2S, and Υ(3S produced in proton-proton (pp and lead-lead (Pb-Pb collisions at the large hadron collider (LHC are uniformly described by a hybrid model of two-component Erlang distribution for pT spectrum and two-component Gaussian distribution for y spectrum. The former distribution results from a multisource thermal model, and the latter one results from the revised Landau hydrodynamic model. The modelling results are in agreement with the experimental data measured in pp collisions at center-of-mass energies s=2.76 and 7 TeV and in Pb-Pb collisions at center-of-mass energy per nucleon pair sNN=2.76 TeV. Based on the parameter values extracted from pT and y spectra, the event patterns (particle scatter plots in two-dimensional pT-y space and in three-dimensional velocity space are obtained.

    The charge asymmetry in t anti t production is a precision test for Standard Model predictions. It arises from interferences between next-to-leading order processes. This measurement offers a good discriminant for new physics models where the asymmetry could behave differently. We present measurements of the t anti t charge asymmetry in the dilepton channel in a fiducial region and for the full phase-space. The inclusive measurement is performed, as well as differential measurements with respect to mass, transverse momentum and the boost of the t anti t system. These studies are done using data with an integrated luminosity of 20 fb{sup -1} in pp collisions at 8 TeV, collected by the ATLAS detector at the LHC.

    Full Text Available Two-particle correlations as a function of Δη and Δφ are used in many colliding systems to study a wide range of physical phenomena. Examples include the collective behavior of the quark-gluon plasma medium, jets, quantum statistics or Coulomb effects, conservation laws, and resonance decays. In this work, measurements of the correlations of identified particles and their antiparticles (for π, K, p, Λ are reported in pp collisions at √s = 7 TeV at low transverse momenta. The analysis reveals differences in particle production between baryons and mesons. The correlation functions for mesons exhibit the expected peak dominated by the effects of mini-jet fragmentation and are reproduced well by general purpose Monte Carlo generators. For baryon pairs where both particles have the same baryon number, an anti-correlation structure is observed instead of a peak centered at (Δη, Δφ = (0, 0; an observation which presents a challenge to models typically used to describe pp data (PYTHIA, PHOJET. This baryon anti-correlation is further interpreted in the context of baryon production mechanisms in the fragmentation processes.

    The reaction pp → pπ + X has been studied at 3 energies (T p 1520, 1805 and 2100 MeV) and 6 angles from 0 angle up to 17 angle (lab.). Several narrow states have been observed in missing mass spectra at: 1004, 1044, 1094 MeV. Their widths are typically one order of magnitude smaller than the widths of N * of Δ. Possible biases are discussed. These masses are in agreement with those calculated within a simple phenomenological mass formula based on color magnetic interaction between two colored quark clusters. (authors)

  11. Phase separation of DMDBS from iPP, and controlled crystalline orientation

    We report an unexpected dependence of DMDBS phase separation temperature on the molecular weight of the matrix isotactic polypropylene (iPP). DMDBS crystallizes out at lower temperatures for iPP with decreasing molecular weight (and correspondingly lower tacticity). This molecular weight dependence is unique to iPP, and is not observed for either syndiotactic PP or for random ethylene-PP copolymers. We show that thermodynamic Flory-type arguments are unable to rationalize the observed results. We also results on extrusion film casting of iPP containing DMDBS and show that flow-alignment of DMDBS networks template the orientation of PP crystals. The modulus and yield strength increase on addition of DMDBS, relative to the neat iPP. Tensile modulus and yield stress of drawn films increase with the degree of orientation, and we are able to achieve a substantial increase even at relatively low draw ratios.

  12. Abaca fibre reinforced PP composites and comparison with jute and flax fibre PP composites

    Directory of Open Access Journals (Sweden)

    2007-11-01

    Full Text Available Abaca fibre reinforced PP composites were fabricated with different fibre loadings (20, 30, 40, 50wt% and in some cases 35 and 45 wt%. Flax and jute fibre reinforced PP composites were also fabricated with 30 wt% fibre loading. The mechanical properties, odour emission and structure properties were investigated for those composites. Tensile, flexural and Charpy impact strengths were found to increase for fibre loadings up to 40 wt% and then decreased. Falling weight impact tests were also carried out and the same tendency was observed. Owing to the addition of coupling agent (maleated polypropylene -MAH-PP, the tensile, flexural and falling weight impact properties were found to increase in between 30 to 80% for different fibre loadings. When comparing jute and flax fibre composites with abaca fibre composites, jute fibre composites provided best tensile properties but abaca fibre polypropylene composites were shown to provide best notch Charpy and falling weight impact properties. Odours released by flax fibre composites were smaller than jute and abaca fibre composites.

    Ser/Thr protein phosphatase 1 (PP1) is a single-domain hub protein with nearly 200 validated interactors in vertebrates. PP1-interacting proteins (PIPs) are ubiquitously expressed but show an exceptional diversity in brain, testis and white blood cells. The binding of PIPs is mainly mediated by short motifs that dock to surface grooves of PP1. Although PIPs often contain variants of the same PP1 binding motifs, they differ in the number and combination of docking sites. This molecular-lego strategy for binding to PP1 creates holoenzymes with unique properties. The PP1 binding code can be described as specific, universal, degenerate, nonexclusive and dynamic. PIPs control associated PP1 by interference with substrate recruitment or access to the active site. In addition, some PIPs have a subcellular targeting domain that promotes dephosphorylation by increasing the local concentration of PP1. The diversity of the PP1 interactome and the properties of the PP1 binding code account for the exquisite specificity of PP1 in vivo. © 2012 The Authors Journal compilation © 2012 FEBS.

  15. Measurement of the cross sections of t anti t production in the boosted regime with the CMS detector at √(s)=8 TeV

    2016-10-01

    In this work the measurement of the t anti t production in ''boosted'' topologies, i.e. with high transverse momenta of the top quark, p_T(t)>400 GeV, in pp collisions at the LHC is presented. It is the first measurement of this kind in the dileptonic final state. By the end of 2012 the CMS detector recorded a data sample which contains of the order of 100 thousand t anti t pairs, which further decay dileptonically (t anti t→W"+bW"- anti b→l"+νbl"- anti ν anti b). The dileptonic final state has a unique signature - two leptons (electrons or/and muons), which are well reconstructed in the detector. The small branching ratio (low statistics) of the dileptonic decay channel of the t anti t system is compensated by an almost background free measurement of the t anti t production. In the presented analysis the kinematics of the t anti t final state is fully reconstructed. For this purpose six kinematic constrains are used to reconstruct the two undetected neutrinos in the t anti t final state. Two specific techniques are employed to account for the requirements of the boosted top quark analysis. Firstly, the spatial isolation of the leptons from hadronic jets in the events, which is important to reject fake leptons out of jets, was optimized by implementing an additional isolation criterion based on the relative transverse momentum of the electron to the jet. Secondly, to effectively suppress significant migrations from the true low p_T(t) values to the boosted region, a kinematic restriction on the ratio of the invariant mass of the visible objects from the t anti t decay to the reconstructed t anti t mass is applied. The obtained cross section results in the high p_T(t) region have a good precision, which is comparable to the one from measurements in the semi-leptonic channel, where hadronically decaying top quarks are reconstructed in the boosted regime as a single ''fat jet''. The measured production cross sections in the dileptonic and in the semi

    Polypropylene (PP) is a biocompatible and biostable polymer, showing good mechanical properties that has been recently introduced in the biomedical field for bone repairing applications; however, its poor surface properties due to its low surface energy limit their use in biomedical applications. In this work, we have studied the topographical modification of polypropylene (PP) laser textured with Nd:YVO4 nanosecond lasers emitting at λ = 1064 nm, 532 nm, and 355 nm. First, optical response of this material under these laser wavelengths was determined. The application of an absorbing coating was also studied. The influence of the laser processing parameters on the surface modification of PP was investigated by means of statistically designed experiments. Processing maps to tailor the roughness, and wettability, the main parameters affecting cell adhesion characteristics of implants, were also determined. Microhardness measurements were performed to discern the impact of laser treatment on the final mechanical properties of PP.

The drillhole ONK-PP262 was drilled in May 2010 and the drillhole ONK-PP274 in December 2010. The lengths of the drillholes are 25.02 and 23.88 m respectively. The drillholes are 75.7 mm by diameter. The drillholes were drilled in the investigation niche 4 at the access tunnel chainage 3747. The hydraulic DE 130 drilling rig was used. The drilling water was taken from the ONKALO drilling water pipeline and premixed sodium fluorescein was used as a label agent in the drilling water. The drillholes were measured with EMS deviation survey tool. In addition to drilling the drillcores were logged and reported by geologist. Geological logging included the following parameters: lithology, foliation, fracture parameters, fractured zones, core loss, weathering, fracture frequency, RQD and rock quality. The main rock types in the drillholes are veined gneiss and pegmatitic granite. The average fracture frequencies in both drill cores are 1.4 pcs/m. The average RQD values in the drillcores are 97.2 % (ONK-PP262) and 98.6 % (ONK-PP274). (orig.)

    Contributions to Λ c + → φΣ, φΛ and p anti K o from excited states are considered. The calculations are performed within the MIT-bag model and a Heavy Quark bag model. Because the mass of Λ c + is rather big compared to the strange baryons, excited baryon states with mass close to that of Λ c + in some cases give significant pole contributions to the decay amplitudes of Λ c + . 20 refs., 3 tabs

    Charged pion exchange, producing nΔ ++ intermediate states, contributes negatively to the weak scattering asymmetry in longitudinally-polarized pp scattering. Including this contribution moves the theoretical prediction away from the 800 MeV experimental datum. The pion-exchange contribution has both inelastic and elastic scattering components and is sizeable even below the pion production threshold. Strong distortions enhance the magnitude of the effect. 14 refs., 5 figs

    Plasticizers or plastic materials such as phthalates, bisphenol-A (BPA), and styrene are widely used in the plastic industry and are suspected endocrine-disrupting chemicals (EDC). Although plastic materials such as polypropylene (PP) and polyethylene terephthalate (PET) are not EDC and are considered to be safe, their potential properties as EDC have not been fully investigated. In this study, plastic samples eluted from plastic food containers (PP or PET) were investigated in Sprague-Dawley rats using Hershberger and uterotrophic assays. In the Hershberger assay, 6-wk-old castrated male rats were orally treated for 10 consecutive days with plastic effluent at 3 different doses (5 ml/kg) or vehicle control (corn oil, 1 ml/100 g) to determine the presence of both anti-androgenic and androgenic effects. Testosterone (0.4 mg/ml/kg) was subcutaneously administered for androgenic evaluation as a positive control, whereas testosterone (0.4 mg/ml/kg) and flutamide (3 mg/kg/day) were administered to a positive control group for anti-androgenic evaluation. The presence of any anti-androgenic or androgenic activities of plastic effluent was not detected. Sex accessory tissues such as ventral prostate or seminal vesicle showed no significant differences in weight between treated and control groups. For the uterotrophic assay, immature female rats were treated with plastic effluent at three different doses (5 ml/kg), with vehicle control (corn oil, 1 ml/100 g), or with ethinyl estradiol (3 μg/kg/d) for 3 d. There were no significant differences between test and control groups in vagina or uterine weight. Data suggest that effluents from plastic food containers do not appear to produce significant adverse effects according to Hershberger and uterotrophic assays.

    Proton-proton and proton-{eta} invariant-mass distributions and the total cross-section for the pp{yields}pp{eta} reaction have been determined near the threshold at an excess energy of Q=10 MeV. The experiment has been conducted using the COSY-11 detector setup and the cooler synchrotron COSY. The determined invariant-mass spectra reveal significant enhancements in the region of low proton-proton relative momenta, similarly as observed previously at higher excess energies of Q=15.5 MeV and Q=40 MeV.

    Full Text Available Die Entwicklung von Polypropylen- Implantaten zur Behandlung von Bauchwandhernien stellt einen Meilenstein in der Geschichte der Chirurgie dar. Mit einigen Jahren Verzug folgten die Urogynäkologen den Chirurgen und begannen, Polypropylen-Netze zur Behebung von Beckenbodenvorfällen einzusetzen. PP910-Netze (Vypro II®, Ethicon und PP25-Netze (Ultrapro®, Ethicon werden seit Langem mit gutem Erfolg bei Hernien-Operationen eingesetzt. Das Ziel dieser Studie war herauszufinden, inwieweit sich diese beiden Netze auch für den Einsatz beim Beckenbodenprolaps eignen. Hierzu wurden Fragebögen an Patientinnen versandt, denen in den Jahren 2003 und 2004 diese Netze im Beckenboden implantiert wurden. Die Hauptfragestellungen waren hierbei, inwiefern sich die Symptome des Vorfalles nach der Behandlung verändert hatten und welche Komplikationen nach der Operation aufgetreten waren. Beide Gruppen zeigten nach dem Netzeinsatz deutliche Verbesserungen der Symptomatik bei einer geringen Komplikationsquote. Beim Einsatz von PP910 zeigten sich in 6 % der Fälle Komplikationen, die auf die Implantation des Netzes zurückgeführt werden konnten. Beim Einsatz von PP25 zeigten sogar nur 1,5 % der operierten Frauen netzbedingte Komplikationen. Somit hat sich gezeigt, dass beide Netze gut für die Verwendung im Beckenboden geeignet sind. Vergleicht man die beiden Netze mit anderen Produkten, die derzeit als Implantate im Beckenboden genutzt werden, so zeigt sich ein sehr positives Ergebnis mit signifikant weniger postoperativen Komplikationen unter der Verwendung von PP25-Netzen. Im Rahmen dieser Analyse konnte festgestellt werden, dass PP25 ein sehr sicheres Netz mit ausgesprochen guten Ergebnissen für die Therapie des Beckenbodenprolaps ist.

    Pectobacterium carotovorum subsp. carotovorum (formerly Erwinia carotovora subsp. carotovora) is a plant pathogen that causes soft rot and stem rot diseases in several crops, including Chinese cabbage, potato, and tomato. To control this bacterium, we isolated a bacteriophage, PP1, with lytic activity against P. carotovorum subsp. carotovorum. Transmission electron microscopy revealed that the PP1 phage belongs to the Podoviridae family of the order Caudovirales, which exhibit icosahedral heads and short non-contractile tails. PP1 phage showed high specificity for P. carotovorum subsp. carotovorum, and several bacteria belonging to different species and phyla were resistant to PP1. This phage showed rapid and strong lytic activity against its host bacteria in liquid medium and was stable over a broad range of pH values. Disease caused by P. carotovorum subsp. carotovorum was significantly reduced by PP1 treatment. Overall, PP1 bacteriophage effectively controls P. carotovorum subsp. carotovorum.

    Measurements of the transverse momentum (p{sub T}) spectra of K{sup 0}{sub s} and Λ(anti Λ) in Pb-Pb and pp collisions at √(s{sub NN})=2.76 TeV with the ALICE detector at the LHC at CERN up to p{sub T}=20 GeV/c and p{sub T}=16 GeV/c, respectively, are presented in this thesis. In addition, the particle rapidity densities at mid-rapidity and nuclear modification factors of K{sup 0}{sub s} and Λ(anti Λ) are shown and discussed. The analysis was performed using the Pb-Pb data set from 2010 and the pp data set from 2011. For the identification of K{sup 0}{sub s} and Λ(anti Λ), the on-the-fly V0 finder was employed on tracking information from the TPC and ITS detectors. The Λ and anti Λ spectra were feed-down corrected using the measured published Ξ{sup -} spectra as input. Regarding the rapidity density at mid-rapidity, a suppression of the strange particle production in pp as compared to Pb-Pb collisions is observed at all centralities, whereas the production per pion rapidity density stays constant as a function of dN{sub ch}/dη including both systems. Furthermore, the relative increase of the individual particle species in pp and AA collisions is compatible for non- and single-strange particles when going from RHIC (√(s{sub NN})=0.2 TeV) to LHC energies. On the other hand, in case of multi-strange baryons, a stronger increase in the particle production in pp is seen. The anti Λ and Λ production in Pb-Pb and pp collisions was found to be equal. Concerning the nuclear modification factors, at lower p{sub T}(p{sub T}<5 GeV/c), an enhancement of the R{sub AA} of Λ with respect to that of K{sup 0}{sub s} and charged hadrons is observed. This baryon-to-meson enhancement appearing in central Pb-Pb collisions at RHIC and LHC is currently explained by the interplay of the radial flow and recombination as the dominant particle production mechanism in this p{sub T} sector. The effect of radial flow is thus also seen in the low and intermediate p{sub T} region

    Full Text Available Placental Protein 13 (PP13, an early biomarker of preeclampsia, is a placenta-specific galectin that binds beta-galactosides, building-blocks of ABO blood-group antigens, possibly affecting its bioavailability in blood.We studied PP13-binding to erythrocytes, maternal blood-group effect on serum PP13 and its performance as a predictor of preeclampsia and intrauterine growth restriction (IUGR. Datasets of maternal serum PP13 in Caucasian (n = 1078 and Hispanic (n = 242 women were analyzed according to blood groups. In vivo, in vitro and in silico PP13-binding to ABO blood-group antigens and erythrocytes were studied by PP13-immunostainings of placental tissue-microarrays, flow-cytometry of erythrocyte-bound PP13, and model-building of PP13--blood-group H antigen complex, respectively. Women with blood group AB had the lowest serum PP13 in the first trimester, while those with blood group B had the highest PP13 throughout pregnancy. In accordance, PP13-binding was the strongest to blood-group AB erythrocytes and weakest to blood-group B erythrocytes. PP13-staining of maternal and fetal erythrocytes was revealed, and a plausible molecular model of PP13 complexed with blood-group H antigen was built. Adjustment of PP13 MoMs to maternal ABO blood group improved the prediction accuracy of first trimester maternal serum PP13 MoMs for preeclampsia and IUGR.ABO blood group can alter PP13-bioavailability in blood, and it may also be a key determinant for other lectins' bioavailability in the circulation. The adjustment of PP13 MoMs to ABO blood group improves the predictive accuracy of this test.

    Full Text Available In the context of Western sanctions caused by the events in Ukraine, a sharp drop in oil prices and other commodity prices, Russia is in a difficult political and economic situation. In these conditions, pressing was the question of replacement technologies and products imported from abroad, especially from the European Union, acceding to the anti-Russian sanctions, initiated by the United States. The political leadership of the Russian Federation have repeatedly raised the issue of import substitution, and only the events of recent years have allowed to translate public policy in this area to the actual implementation of programs developed its own production of goods and technology that were previously imported from abroad.Objective: To analyze the current political developments in the modern world and show the pros and cons of the policy of import substitution in Russia in terms of anti-Russian sanctions.Method and methodology of work: Institutional and neo-institutional paradigm, systematic approach.Results: The authors note that the import substitution program in import substitution, in spite of the marked complexity, have a good chance of success, and this is the key to low-cost raw materials, relatively cheap labor, cheap energy sources – natural gas and electricity, as well as carried out in 2014–2015 devaluation of the ruble, which significantly reduce the cost of the potential costs of enterprises.Application of the results: political science and practice, economic policy.

    The human being is daily exposed to free radicals or reactive oxygen species (Ros), as a result of the breathing and the interactions with xenobiotics that can cause irreversible lesions in molecules and cellular structures and that they are associated to diseases like the cancer, neuro degenerative and to the acceleration of the normal process of aging. Fortunately, to reduce the damaging effect of the Ros the cell has endogenous antioxidant systems constituted by antioxidant enzymes as: the superoxide dismutase (Sod), the catalase (Cat), and the glutathione peroxidase and reductase. Even, when these systems are not enough, we find to the exogenous antioxidants that cooperate in the balance of the Ros, as the porphyrins that include to the chlorophyllin, the hemin and the bilirubin among others. The protoporphyrin-Ix (Pp-Ix) is a tetra pyrrole without metallic center with antimutagenic and antioxidant activity similar to that of the chlorophyllin. However, is also known that their over-expression has toxic effects, because induces Ros. In Drosophila melanogaster, recently was found that the Pp-Ix have dual action anti and persistent mutagenic. One of their possible mechanism to act like mutagen is through the Ros induction. To evaluate this possibility and based in that the increase in the Ros levels can accelerate the aging process, in the present work the Pp-Ix role was evaluated, in the life period of Drosophila melanogaster strains deficient in Sod and Cat, sensitive to radiation or oxidative stress (rad, whd and flr 3 ) and a wild one as control (C-S). Females and males of each strain were treated chronically for separate with sucrose or Pp-Ix and every 15 days a group of each sex was irradiated with 10 Gy of gamma rays. The results indicated that the chronic treatment with Pp-Ix and in combination with radiation, increased the life period of the C-S strain. The Sod strain had a contrary effect and this effect was pronounced with the combined treatment of Pp

    Studies using in vitro cultured oocytes have indicated that the protein phosphatase 2A (PP2A), a major serine/threonine protein phosphatase, participates in multiple steps of meiosis. Details of oocyte maturation regulation by PP2A remain unclear and an in vivo model can provide more convincing information. Here, we inactivated PP2A by mutating genes encoding for its catalytic subunits (PP2Acs) in mouse oocytes. We found that eliminating both PP2Acs caused female infertility. Oocytes lacking PP2Acs failed to complete 1(st) meiotic division due to chromosome misalignment and abnormal spindle assembly. In mitosis, PP2A counteracts Aurora kinase B/C (AurkB/C) to facilitate correct kinetochore-microtubule (KT-MT) attachment. In meiosis I in oocyte, we found that PP2Ac deficiency destabilized KT-MT attachments. Chemical inhibition of AurkB/C in PP2Ac-null oocytes partly restored the formation of lateral/merotelic KT-MT attachments but not correct KT-MT attachments. Taken together, our findings demonstrate that PP2Acs are essential for chromosome alignments and regulate the formation of correct KT-MT attachments in meiosis I in oocytes.

    Dynamic assembly/disassembly of signaling complexes are crucial for cellular functions. Specialized latency and activation chaperones control the biogenesis of protein phosphatase 2A (PP2A) holoenzymes that contain a common scaffold and catalytic subunits and a variable regulatory subunit. Here we show that the butterfly-shaped TIPRL (TOR signaling pathway regulator) makes highly integrative multibranching contacts with the PP2A catalytic subunit, selective for the unmethylated tail and perturbing/inactivating the phosphatase active site. TIPRL also makes unusual wobble contacts with the scaffold subunit, allowing TIPRL, but not the overlapping regulatory subunits, to tolerate disease-associated PP2A mutations, resulting in reduced holoenzyme assembly and enhanced inactivation of mutant PP2A. Strikingly, TIPRL and the latency chaperone, α4, coordinate to disassemble active holoenzymes into latent PP2A, strictly controlled by methylation. Our study reveals a mechanism for methylation-responsive inactivation and holoenzyme disassembly, illustrating the complexity of regulation/signaling, dynamic complex disassembly, and disease mutations in cancer and intellectual disability.

    Measurements of neutral transverse energy spectra in p-p, d-d and α-α interactions at the CERN ISR are presented. The source of transverse energy is the emission of relatively low P/sub T/ particles distributed uniformly. Analysis of the αα data in terms of multiple nucleon-nucleon collisions is most convenient when Gamma distributions are used to represent the spectral shapes. This distribution bears a strong relationship to the Negative Binomial Distribution which describes multiplicity distributions in pp and p anti p interactions over the full available energy range. Extensive analysis of the data is presented in terms of Nuclear Models. However, the best fit to the pp and αα data is a single Gamma distribution scaled by the mean value. This property is also known as KNO scaling. 15 refs., 2 figs

    We have performed a high-statistics search for narrow meson states (GAMMA - p interactions at 16 GeV/c and decaying into pp-barπ + or Λp-barπ +- . This is the first systematic search in channels requiring exchange of exotic mesons. The cross section for production of such states is ruled out at the 95% confidence level with upper limits ranging from approx.10 nb at 2.3 GeV to approx.40 nb at 2.8 GeV

  18. Ex vivo modulation of the Foxo1 phosphorylation state does not lead to dysfunction of T regulatory cells.

    Full Text Available Peripheral regulatory CD4+ T cells (Treg cells prevent maladaptive inflammatory responses to innocuous foreign antigens. Treg cell dysfunction has been linked to many inflammatory diseases, including allergic airway inflammation. Glucocorticoids that are used to treat allergic airway inflammation and asthma are thought to work in part by promoting Treg cell differentiation; patients who are refractory to these drugs have defective induction of anti-inflammatory Treg cells. Previous observations suggest that Treg cells deficient in the transcription factor FoxO1 are pro-inflammatory, and that FoxO1 activity is regulated by its phosphorylation status and nuclear localization. Here, we asked whether altering the phosphorylation state of FoxO1 through modulation of a regulatory phosphatase might affect Treg cell function. In a mouse model of house dust mite-induced allergic airway inflammation, we observed robust recruitment of Treg cells to the lungs and lymph nodes of diseased mice, without an apparent increase in the Treg cytokine interleukin-10 in the airways. Intriguingly, expression of PP2A, a serine/threonine phosphatase linked to the regulation of FoxO1 phosphorylation, was decreased in the mediastinal lymph nodes of HDM-treated mice, mirroring the decreased PP2A expression seen in peripheral blood monocytes of glucocorticoid-resistant asthmatic patients. When we asked whether modulation of PP2A activity alters Treg cell function via treatment with the PP2A inhibitor okadaic acid, we observed increased phosphorylation of FoxO1 and decreased nuclear localization. However, dysregulation of FoxO1 did not impair Treg cell differentiation ex vivo or cause Treg cells to adopt a pro-inflammatory phenotype. Moreover, inhibition of PP2A activity did not affect the suppressive function of Treg cells ex vivo. Collectively, these data suggest that modulation of the phosphorylation state of FoxO1 via PP2A inhibition does not modify Treg cell function ex

    By using (pp) interactions at three different CM energies, ( \\sqrt{s})/sub pp/=30, 44, 62 GeV, it is shown that the average charged- particle multiplicity (n/sub ch/) vs. the invariant mass of the hadronic system m/sub 1,2/ has the same behaviour as it has vs. 2E/sup had/. Moreover, in both cases (n/sub ch/) is shown to be nearly independent of ( \\sqrt{s})/sub pp/ and in good agreement with the average charged-particle multiplicity measured in the (e^{+}e/sup - /) annihilation.

    In nucleus-nucleus collisions, the Quark-Gluon Plasma behaves like a perfect fluid and the azimuthal anisotropy of the observed particle final-state distributions reflects its properties. This anisotropic flow, arising mainly from initial-state geometry and its fluctuations, highlights the collective behavior of the particles produced in the collision. It is well-described by hydrodynamics and explains the long-range near-side correlations, known as the ridge, observed experimentally in AA collisions and, more recently, in small systems such as pp or pA collisions. The CMS experiment has studied this correlation in details by extracting the momenta of the Fourier decomposition of azimuthal particle-distribution in the final state ($v_{\\mathrm{n}}$, n = 2 - 4). The $v_{\\mathrm{n}}$ are extracted using di-hadron correlation and multi-particle cumulant methods in both pp and pPb collisions. In this talk, results from CMS on the ridge in small systems are shown and compared with those in PbPb collisions, demonstr...

    A search for supersymmetry or other new physics resulting in similar final states is presented using a data sample of 4.73 inverse femtobarns of pp collisions collected at $ \\sqrt{s}=7 $ TeV with the CMS detector at the LHC. Fully hadronic final states are selected based on the variable MT2, an extension of the transverse mass in events with two invisible particles. Two complementary studies are performed. The first targets the region of parameter space with medium to high squark and gluino masses, in which the signal can be separated from the standard model backgrounds by a tight requirement on MT2. The second is optimized to be sensitive to events with a light gluino and heavy squarks. In this case, the MT2 requirement is relaxed, but a higher jet multiplicity and at least one b-tagged jet are required. No significant excess of events over the standard model expectations is observed. Exclusion limits are derived for the parameter space of the constrained minimal supersymmetric extension of the standard model, as well as on a variety of simplified model spectra.

  2. Study of PP/Polybutene Blends Modified by Gamma Irradiation and HMS-PP/Polybutene Blends

    The polypropylene (PP) has been applied to a wide range of production due to its various excellent properties such as cheapness, high stiffness, chemical resistance, no environmental pollution when incinerated, low specific density and good mechanical properties. However, PP is a linear polymer which exhibits low melt strength. One of the effective approaches to achieve high melt strength (HMS) is to add chain branches onto backbone polymers. High melt strength polypropylene (HMS-PP) has been recently developed and introduced in the market by the major international polypropylene producers. As a consequence different methods have been applied to modify polypropylenes by chain branches. The technology obtained by IPEN together with EMBRARAD and BRASKEM comprises chain branches added onto backbone species using gamma radiation, which is generated from a Co 6 0 source. Such radiation is very convenient in order to improve polymer materials by grafting, crosslinking and degradation. Another important approach to the development of polymer materials is based on the combination of different polymers into a new product having some of the desired properties of each component. In this work, gamma irradiation technique was used to induce chemical changes in commercial polypropylene (HMS-PP) that was after blended with polybutene and in polypropylene/polybutene blends. The samples were irradiated with a 60 C o source at doses of 12,5 and 20kGy in the presence of acetylene. It was investigated how the two different routes of blends processing can modify their properties. Indeed the results from melt flow, gel fraction and rheology reveal the influence of the process route in the blends properties. Effects on the elongation at break and break strength were observed by the results of mechanical tests. The results from rheology demonstrated an increase in melt strength and drawability of the blends

  3. Measurement of the radial profile of $D^{0}$ mesons in jets produced in pp and PbPb collisions at 5.02 TeV

    The first measurement of the radial distributions of $D^{0}$ mesons in jets in PbPb and pp collisions is presented. Data samples of PbPb and pp collisions at a nucleon-nucleon center-of-mass energy of $\\sqrt{s_{NN}}=5.02$ $\\mathrm{TeV}$, corresponding to integrated luminosities of 404 $\\mu \\rm b^{-1}$ and 27.4 $\\rm p b^{-1}$, respectively, are recorded by the CMS detector at the LHC. The jets are reconstructed with an anti-$k_{T}$ algorithm with a distance parameter of $0.3$. The radial distribution of $D^{0}$ mesons with transverse momentum $p_{\\mathrm{T}}>4 \\,\\mathrm{Ge\\hspace{-.08em}V\\hspace{-0.16em}/\\hspace{-0.08em}}c$ are measured with respect to the jet axis. Modifications of $D^{0}$ radial distribution in PbPb collisions are presented by comparing PbPb spectra to the pp reference data, indicating a redistribution of the $D^{0}$ mesons close to the jet axis. This measurement provides new experimental constraints on the mechanisms of heavy-flavor production in proton-proton collisions as well as on the p...
