  1. Calibration of the ATLAS precision muon chambers and study of the decay {tau} {yields} {mu}{mu}{mu} at the large hadron collider

    Energy Technology Data Exchange (ETDEWEB)

    Loeben, Joerg Horst Jochen von

    2010-07-07

    The Large Hadron Collider (LHC) is designed to collide protons at centre-of-mass energies of up to 14 TeV. One of the two general purpose experiments at the LHC is ATLAS, built to probe a broad spectrum of physics processes of the Standard Model of particle physics and beyond. ATLAS is equipped with a muon spectrometer comprising three superconducting air-core toroid magnets and 1150 precision drift tube (MDT) chambers measuring muon trajectories with better than 50 {mu}m position resolution. The accuracy of the space-to-drift-time relationships of the MDT chambers is one of the main contributions to the momentum resolution. In this thesis, an improved method for the calibration of the precision drift tube chambers in magnetic fields has been developed and tested using curved muon track segments. An accuracy of the drift distance measurement of better than 20 {mu}m is achieved leading to negligible deterioration of the muon momentum resolution. The second part of this work is dedicated to the study of the lepton flavour violating decay {tau}{yields}{mu}{mu}{mu}. Lepton flavour violation is predicted by almost every extension of the Standard Model. About 10{sup 12}{tau} leptons are produced per year at an instantaneous luminosity of 10{sup 33} cm{sup -2}s{sup -1} and a centre-of-mass energy of 14 TeV. Simulated data samples have been used to evaluate the sensitivity of the ATLAS experiment for {tau}{yields}{mu}{mu}{mu} decays with an integrated luminosity of 10 fb{sup -1}. Taking theoretical and experimental systematic uncertainties into account an upper limit on the signal branching ratio of B({tau}{yields}{mu}{mu}{mu}) <5.9 x 10{sup -7} at 90% confidence level is achievable. This result represents the first estimation in ATLAS. (orig.)

    A few studies of the behaviour of positive muons in metal hydrides have been made during the last three years under the code SC76, although this code is intended primarily for ``diffusion and trapping of positive muons`` in pure or very weakly doped metals. It has been shown in these studies that $\\mu$SR can provide important information even in concentrated hydrides like $ NbH _{,} _{0},7 - _{0} _{,} _{9} $ and $ Zr V _{2} H _{2} _{m}inus _{3} $ especially concerning mutual $\\mu

    This thesis shows the strategy to extract the $B_s\\rightarrow\\mu^{+}\\mu^{-}$ branching ratio from the LHCb data, calibrating all the steps using control channels and not relying on the simulation. This branching ratio is very sensitive to New Physics effects, and can get large enhancements within SuperSymmetry or other Standard Model extensions. The signal is separated from background according to three properties: the invariant mass, the muon identification, and the geometrical properties of the decay. The multivariate analysis designed to combine the geometrical properties is also shown here. The ration of offline reconstruction efficiencies between signal ($B_s\\rightarrow\\mu^{+}\\mu^{-}$) and normalization channels ($B^{+}\\rightarrow J/\\psi(\\mu^{+}\\mu^{-}K^{+}$ and/or $B_d\\rightarrow K ^{+}\\pi^{-}$ ) can be extracted using the ratio of different control channels (for instance, $B_d\\rightarrow J/\\psi (\\mu^{+}\\mu^{-}) K^{*0}(K^{+}\\pi^{-}))$ with a few percent precision. The ratio of trigger efficiencies can b...

    Full text of publication follows: Risk assessments of actinide-contaminated soils and sediments require detailed knowledge of actinide speciation and its long-term kinetics. Former Saxonian mine tailings, which have been covered but else left undisturbed, are ideally suited to study changes in uranium speciation over timescales of decades. We investigated the major uranium species in two samples from buried mine tailings using a combination of Synchrotron-based microfocus-techniques ({mu}-XRF, {mu}-XRD with micrometer resolution), bulk EXAFS spectroscopy, and chemical extractions. In sample F1 (5 m depth, oxic, pH 8, U = 440 mg/kg, high Ca, S, Pb, Cu, Zn concentrations), uranium is diffusely distributed among aggregates of layer silicates (muscovite, illite and kaolinite). The chemical extractions and EXAFS results confirm that uranium is sorbed to these minerals, but is not incorporated into their crystal structure. Sorption is also in line with the high pH and low carbonate concentrations in pore water. In sample F3 (12 m depth, oxic, pH 4, U = 430 mg/kg), the combination of {mu}-XRF and {mu}-XRD enabled us to identify several U(IV) and U(VI) containing minerals like coffinite, uraninite, uranyl hydroxide, and vanuralite. Only a minor part of U is sorbed to layer silicates as confirmed by chemical extractions and EXAFS spectroscopy. At smaller depth (F1, 5 m), sulfuric acid from the ore extraction procedure was completely neutralized by the construction waste used as cover material, resulting in precipitation of jarosite and gypsum. Even 30 years after the ore extraction, uranium remains highly soluble. At greater depth (F3, 12 m), the low pH from ore extraction was conserved. The presence of U(IV) minerals suggest either precipitation of secondary (IV) minerals due to microbial redox activity, or incomplete dissolution of primary (IV) minerals due to ore processing inefficiency of these older sediments. The U(IV) minerals were recalcitrant during chemical

    The ATLAS Experiment has conducted a search for the rare decays of Bs and Bd into mu+mu-. 25 fb−1 of integrated luminosity of proton-proton collisions collected during LHC Run 1 were studied to provide new results presented in this talk. An upper limit is set on the branching ratio BR(Bd to mu+mu-) < 4.2×10−10 at 95% confidence level. For Bs, ATLAS measurement yields the branching ratio BR(Bs to mu+mu-)=(0.9+1.1−0.8)×10−9. The result is consistent with the Standard Model expectation and other available measurements.

    To identify the main toxic gas released from salted radish in rice bran(Dan-Mu-Ji) and to introduce the radiological findings of the patient who was exposed to the gas. Chest radiographs and CT scans of one survivor among three men who were exposed to the gas from Dan-Mu-Ji were reviewed. Gas obtained from the closed bottle containing Dan-Mu-Ji was analyzed by using the gas chromatography. The radiographic examinations of the survivor were suggestive of pulmonary edema with it's rapidly improving consideration in both lung. The headspace gas within the bottle containing Dan-Mu-Ji was mainly composed with carbon dioxide, ethyl alcohol and hydrogen sulfide, of which hydrogen sulfide was considered the main toxic gas released. Under the anaerobic condition, Dan-Mu-Ji released toxic hydrogen sulfide. Inhalation of hydrogen sulfide might produce non-cardiogenic pulmonary edema.

    A search for the decays $B^0_s \\to \\mu^+\\mu^-\\mu^+\\mu^-$ and $B^0 \\to \\mu^+\\mu^-\\mu^+\\mu^-$ in a data sample of 1.0 inverse femtobarns collected with the LHCb detector in 2011 is discussed. In the SM, the non-resonant $B^0_s \\to \\mu^+\\mu^-\\mu^+\\mu^-$ branching fraction is expected to be < 10$^{-10}$. One signal candidate is observed in the $B_d$ channel, and no signal candidates are observed in the $B_s$ channel. These observed events are consistent with the expected backgrounds and upper limits on the branching fractions are set at $\\cal{B}(B^0_s \\to \\mu^+\\mu^-\\mu^+\\mu^-) < 1.3 \\times 10^{-8}$ and $\\cal{B}(B^0 \\to \\mu^+\\mu^-\\mu^+\\mu^-) < 5.4 \\times 10^{-9}$ at 95 % CL.

  10. Identification and Molecular Characterisation of a Novel Mu-Like Bacteriophage, SfMu, of Shigella flexneri.

    Directory of Open Access Journals (Sweden)

    Richa Jakhetia

    Full Text Available S. flexneri is the leading cause of bacillary dysentery in the developing countries. Several temperate phages originating from this host have been characterised. However, all S. flexneri phages known to date are lambdoid phages, which have the ability to confer the O-antigen modification of their host. In this study, we report the isolation and characterisation of a novel Mu-like phage from a serotype 4a strain of S. flexneri. The genome of phage SfMu is composed of 37,146 bp and is predicted to contain 55 open reading frames (orfs. Comparative genome analysis of phage SfMu with Mu and other Mu-like phages revealed that SfMu is closely related to phage Mu, sharing >90% identity with majority of its proteins. Moreover, investigation of phage SfMu receptor on the surface of the host cell revealed that the O-antigen of the host serves as the receptor for the adsorption of phage SfMu. This study also demonstrates pervasiveness of SfMu phage in S. flexneri, by identifying complete SfMu prophage strains of serotype X and Y, and remnants of SfMu in strains belonging to 4 other serotypes, thereby indicating that transposable phages in S. flexneri are not uncommon. The findings of this study contribute an advance in our current knowledge of S. flexneri phages and will also play a key role in understanding the evolution of S. flexneri.

    A search for the rare decays B0s->pi pi mu mu and B0->pi pi mu mu is performed in a data set corresponding to an integrated luminosity of 3.0 fb-1 collected by the LHCb detector in proton-proton collisions at centre-of-mass energies of 7 and 8TeV. Decay candidates with pion pairs that have invariant mass in the range 0.5--1.3 GeV/c2 and with muon pairs that do not originate from a resonance are considered. The first observation of the decay B0s->pi pi mu mu and the first evidence of the decay B0->pi pi mu mu are obtained and the branching fractions, restricted to the dipion-mass range considered, are measured to be Br(B0s->pi pi mu mu) = (8.6 +/- 1.5 (stat) +/- 0.7 (syst) +/- 0.7 (norm))*10^-8 and Br(B0->pi pi mu mu) = (2.11 +/- 0.51 (stat) +/- 0.15 (syst) +/- 0.16 (norm)) *10^-8, where the third uncertainty is due to the branching fraction of the decay B0->J/psi K*, used as a normalisation.

  12. Opiate-induced seizures: a study of mu and delta specific mechanisms.

    Science.gov (United States)

    Snead, O C

    1986-08-01

    Two groups of experiments were conducted to determine if morphine- and enkephalin-induced seizures are specifically mediated by the mu and delta receptor, respectively. In the first experiments, designed to assess the ontogeny of mu- or delta-seizures, rats from 6 h to 85 days of age received implanted cortical and depth electrodes as well as an indwelling cannula in the lateral ventricle. Various amounts of the mu-receptor agonists, morphine and morphiceptin, and the delta agonists, D-Ala2-D-Leu5-enkephalin (DADL) and Tyr-D-Ser-Gly-Phe-Leu-Thr (DSLET), were then administered intracerebroventricularly (icv) with continuous EEG monitoring. The second experiments entailed use of the nonspecific opiate antagonist, naloxone, as well as the specific delta antagonist, ICI 154,129, against seizures induced by icv-administered morphine, morphiceptin, DADL, or DSLET. Both morphine and morphiceptin produced electrical seizure activity in rats as young as 5 days after birth. The drugs produced similar seizure activity in terms of electrical morphology, observed behavior, ontogeny, threshold dose, and reversibility with small doses of naloxone. In the pharmacologic experiments, icv naloxone blocked all opiate-induced seizures. ICI 154,129 blocked DSLET seizure, had little effect on enkephalin or DADL seizures, and no effect on morphine or morphiceptin seizures. These data indicate that DSLET seizures are delta-specific but that all other opiate-induced seizures studied may involve multiple opiate receptor-mediated mechanisms.

    Full Text Available Modifier genes contribute to the diverse clinical manifestations of hypertrophic cardiomyopathy (HCM, but are still largely unknown. Muscle ring finger (MuRF proteins are a class of muscle-specific ubiquitin E3-ligases that appear to modulate cardiac mass and function by regulating the ubiquitin-proteasome system. In this study we screened all the three members of the MuRF family, MuRF1, MuRF2 and MuRF3, in 594 unrelated HCM patients and 307 healthy controls by targeted resequencing. Identified rare variants were confirmed by capillary Sanger sequencing. The prevalence of rare variants in both MuRF1 and MuRF2 in HCM patients was higher than that in control subjects (MuRF1 13/594 (2.2% vs. 1/307 (0.3%, p = 0.04; MuRF2 22/594 (3.7% vs. 2/307 (0.7%; p = 0.007. Patients with rare variants in MuRF1 or MuRF2 were younger (p = 0.04 and had greater maximum left ventricular wall thickness (p = 0.006 than those without such variants. Mutations in genes encoding sarcomere proteins were present in 19 (55.9% of the 34 HCM patients with rare variants in MuRF1 and MuRF2. These data strongly supported that rare variants in MuRF1 and MuRF2 are associated with higher penetrance and more severe clinical manifestations of HCM. The findings suggest that dysregulation of the ubiquitin-proteasome system contributes to the pathogenesis of HCM.

    This thesis has been focused on the study of the Z-> mu mu process, using data collected during 2010 with the ATLAS experiment. From the detector performance point of view, the Z->mumu process is used to measure muon trigger and reconstruction efficiencies form data. To this aim, a Tag&Probe method has been developed and optimized in the past years using Monte Carlo simulation. The thesis describes both the method, the softwere developed to implement it, and the results obtained using a data sample of 1.3 pbi of integrated luminosity. The computed muon efficiencies have been then used to derive the data/MC scale factor needed for the Z->mumu cross-section measurement. In this measurement the signal efficiency and acceptance is computed used the MC simulation and has to be corrected to match the observed data performances using the scale factors. The measurement of both Z->mumu inclusive and differential cross-sections with respect to the jet multiplicity in the event, performed during the PhD work, i...

    We report the recent topics in {mu}SR studies on the high-T{sub c} Superconductors, especially about the studies on Zn-doped Bi-2212 system, Bi{sub 2}Sr{sub 2}Ca{sub 1-x}Y{sub x}(Cu{sub 1-y}Zn{sub y})O{sub 8+{delta}}. Zero-field muon spin relaxation ({mu}SR) measurement was applied to this Zn-doped Bi2212 system to study a possibility of the so called `1/8 problem` which was established in high-T{sub c} La-systems. The muon spin depolarization rate increased with decreasing temperature below 10 K in only the Zn-doped (y=0.025) system in which the hole density was 1/8 (x=0.3125), indicating the slowing down behavior of the Cu-spin fluctuations. A long range coherent ordering of the Cu-spins which were the similar to the one observed in the La-systems was not confirmed down to 0.3 K. Both of the Zn-doping and the 1/8 hole density were essential for the freezing of the Cu-spin fluctuations in also the Zn-doped Bi2212 system. (author)

    After a short introduction to {mu}SR with respect to the study of magnetic properties, followed by a brief outline of the principle of the high pressure-low temperature {mu}SR spectrometer installed at the Paul Scherrer Institute, we discuss some measurements on rare earth materials employing this instrument. They are concerned with: (1) The pressure dependence of the spin turning process in ferromagnetic Gd. (2) The volume dependence of the internal magnetic field in the heavy rare earth metals Gd, Dy, and Ho in their ordered magnetic states. (3) The response of the (first order) magnetic transition in the frustrated antiferromagnets of type RMn{sub 2} (R = Y,Gd) to pressure. (4) The variation of magnetic parameters with pressure in La{sub 2}CuO{sub 4} (powder sample), the antiferromagnetic parent compound of the high T{sub C} superconductors of type La{sub 2-x}(Sr, Ba){sub x}CuO{sub 4}. In conclusion a short outlook on further developments is given.

    Muon tomography is based on recording the difference of absorption of muons by matter, as ordinary radiography does for using X-rays. The interaction of cosmic rays with the atmosphere produces extensive air showers which provides an abundant source for atmospheric muons, benefiting various applications of muon tomography, particularly the study of the inner structure of volcanoes. The MuTe (for Muon Telescope) is a hybrid detector composed of scintillation bars and a water Cherenkov detector designed to measure cosmic muon flux crossing volcanic edifices. This detector consists of two scintillator plates (1.44 m2 with 30 x 30 pixels), with a maximum distance of 2.0m of separation. In this work we report the first simulation of the MuTe using GEANT4 -set of simulation tools, based in C++ - that provides information about the interaction between radiation and matter. This computational tool allows us to know the energy deposited by the muons and modeling the response of the scintillators and the water cherenkov detector to the passage of radiation which is crucial to compare to our data analysis.

    The main characteristics of accelerated aluminum targets, which are the target velocity, the uniformity of the acceleration and the backside temperature have been studied in laser experiments performed at wavelength 0.26 ..mu..m with an absorbed flux of a few 10/sup 13/ W/cm/sup 2/, in 400-ps pulse duration by using the double-foil technique and an optical pyrometry diagnostic: The ablation pressure was inferred from the velocity measurements. The uniformity of the acceleration was shown to be controlled by the hot spots in the focal spot, and the importance of studying the smoothing of laser inhomogeneities for accelerated targets with large ablated fractions was emphasized. The observed dependence of the backside temperature as a function of the initial foil thickness is discussed in the light of shock wave heating and radiative heating.

    The reaction of 2-methyl-3-buten-2-ol (MBO) with Mu was investigated for the first time. The free-radical addition products of reactions with Mu are characterized by a combination of transverse field-muSR (TF-muSR) and level crossing resonance (LCR) methods. Density functional theory calculations were also performed to obtain optimized structures of the reactants, transition states and products. The activation energies, energies of reactions and hyperfine coupling constants were calculated and used to characterize the formed radicals. Quantum calculations of the energetics of the Mu+MBO reaction in the gas-phase predicted reaction energies of -15.6 and -19.0 kcal mol{sup -1}, with addition to the terminal carbon predicted to be favoured.

    The branching fractions of the decays $B^{0} \\to \\mu^{+} \\mu^{-}$ and $B_{s}^{0} \\to \\mu^{+} \\mu^{-}$ are highly suppressed in the Standard Model but can be modified by contributions from new physics models. The combined result from the CMS and LHCb Run 1 data for the $B^{0} \\to \\mu^{+} \\mu^{-}$ and $B_{s}^{0} \\to \\mu^{+} \\mu^{-}$ branching fractions is presented here. The measured results are $\\mathcal{B}(B_{s}^{0} \\to \\mu^{+} \\mu^{-}) = (2.8^{+0.7}_{-0.6})\\times 10^{-9}$ at $6.2 \\sigma$ statistical significance and $\\mathcal{B}(B^{0} \\to \\mu^{+} \\mu^{-}) = (3.9^{+1.6}_{-1.4})\\times 10^{-10}$ at $3.0 \\sigma$ statistical significance, both results are consistent with Standard Model predictions. A brief discussion of the future prospects for the study of $B^{0} \\to \\mu^{+} \\mu^{-}$ and $B_{s}^{0} \\to \\mu^{+} \\mu^{-}$ at the LHCb is also included.

    The Flavour Changing Neutral Current decay B to mu mu K, which only occurs via loop processes in the SM, is sensitive to contributions from a variety of possible new physics sources. LHCb, the dedicated b physics experiment at the LHC, will record an unprecedented number of B to mu mu K decays, allowing precision measurements of a large number of variables, which will provide evidence or place constraints for physics beyond the SM. This poster gives a short overview of the detector, introduces some of these variables and presents a selection for B to mu mu K.

    The center for applied isotope studies has developed a protocol for the measurement of radiocarbon in the range 0.01-0.3 mg of carbon. We analyzed a series of radiocarbon-free and modern standards using the same sample preparation procedure as for unknown samples. We have studied the size dependency of {sup 12}C and {sup 13}C beam currents and {sup 14}C/{sup 13}C ratios from cathodes containing less than 1 mg of carbon. The iron catalyst used for graphite preparation contains some carbon with activity about 60 pMC and the level of contamination varies between batches from the same supplier. The cathodes in the range smaller than 50 {mu}g showed a very significant dependency between current and the sample size. In this range the current increased by about fifteen-fold; between 50 and 100 {mu}g the current increased two-fold. Samples larger than 300 {mu}g have shown negligible current variation. The {sup 14}C/{sup 13}C ratio was significantly affected only for the samples less than 50 {mu}g. Larger samples have shown very little variation in the {sup 14}C/{sup 13}C ratio. For the measurement of ultra-small unknown samples in the range of 10-50 {mu}g, we have found it to be important to use blanks and modern standards with exactly the same amount of carbon, which makes it possible to apply a mass-balanced correction.

    Full Text Available While there have been studies exploring regulatory variation in one or more tissues, the complexity of tissue-specificity in multiple primary tissues is not yet well understood. We explore in depth the role of cis-regulatory variation in three human tissues: lymphoblastoid cell lines (LCL, skin, and fat. The samples (156 LCL, 160 skin, 166 fat were derived simultaneously from a subset of well-phenotyped healthy female twins of the MuTHER resource. We discover an abundance of cis-eQTLs in each tissue similar to previous estimates (858 or 4.7% of genes. In addition, we apply factor analysis (FA to remove effects of latent variables, thus more than doubling the number of our discoveries (1,822 eQTL genes. The unique study design (Matched Co-Twin Analysis--MCTA permits immediate replication of eQTLs using co-twins (93%-98% and validation of the considerable gain in eQTL discovery after FA correction. We highlight the challenges of comparing eQTLs between tissues. After verifying previous significance threshold-based estimates of tissue-specificity, we show their limitations given their dependency on statistical power. We propose that continuous estimates of the proportion of tissue-shared signals and direct comparison of the magnitude of effect on the fold change in expression are essential properties that jointly provide a biologically realistic view of tissue-specificity. Under this framework we demonstrate that 30% of eQTLs are shared among the three tissues studied, while another 29% appear exclusively tissue-specific. However, even among the shared eQTLs, a substantial proportion (10%-20% have significant differences in the magnitude of fold change between genotypic classes across tissues. Our results underline the need to account for the complexity of eQTL tissue-specificity in an effort to assess consequences of such variants for complex traits.

    Non-viral gene delivery methods are considered due to safety and simplicity in human gene therapy. Since the use of cationic peptide and niosome represent a promising approach for gene delivery purposes we used recombinant fusion protein and cationic niosome as a gene carrier. A multi-domain fusion protein including nuclear localization motif (NLS) and two DNA-binding (Mu) domains, namely NLS-Mu-Mu (NMM) has been designed, cloned and expressed in E. coli DE3 strain. Afterward, the interested protein was purified by affinity chromatography. Binary vectors based on protein/DNA and ternary vectors based on protein/DNA/niosome were prepared. Protamine was used as a control. DNA condensing properties of NMM and protamine were evaluated by various experiments. Furthermore, we examined cytotoxicity, hemolysis and transfection potential of the binary and ternary complexes in HEK293T and MCF-7 cell lines. Protamine and Lipofectamine™2000 were used as positive controls, correspondingly. The recombinant NMM was expressed and purified successfully and DNA was condensed efficiently at charge ratios that were not harmful to cells. Peptidoplexes showed transfection efficiency (TE) but ternary complexes had higher TE. Additionally, NMM ternary complex was more efficient compared to protamine ternary vectors. Our results showed that niosomal ternary vector of NMM is a promising non-viral gene carrier to achieve an effective and safe carrier system for gene therapy.

    A search for the decays $B^0_{s}\\rightarrow \\mu^+ \\mu^- \\mu^+ \\mu^-$ and $B^0 \\rightarrow \\mu^+ \\mu^- \\mu^+ \\mu^-$ is performed using data, corresponding to an integrated luminosity of 1.0 fb$^{-1}$, collected with the LHCb detector in 2011. The number of candidates observed is consistent with the expected background and, assuming phase-space models of the decays, limits on the branching fractions are set: ${\\cal B}(B^0_{s}\\rightarrow \\mu^+ \\mu^- \\mu^+ \\mu^-) < 1.6 \\ (1.2) \\times 10^{-8}$ and ${\\cal B}(B^0 \\rightarrow \\mu^+ \\mu^- \\mu^+ \\mu^-)< 6.6 \\ (5.3) \\times 10^{-9}$ at 95% (90%) confidence level. In addition, limits are set in the context of a supersymmetric model which allows for the $B^0_{(s)}$ meson to decay into a scalar ($S$) and pseudoscalar particle ($P$), where $S$ and $P$ have masses of 2.5 GeV/c$^2$ and 214.3 MeV/c$^2$, respectively, both resonances decay into $\\mu^+\\mu^-$.

  9. Studies of vertical fluxes of horizontal momentum in the lower atmosphere using the MU-radar

    Full Text Available We study the momentum flux of the atmospheric motions in the height ranges between 6 and 22 km observed using the MU radar at Shigaraki in Japan during a 3 day period in January 1988. The data were divided by double Fourier transformation into data set of waves with downward- phase- velocity and data set of waves with upward-phase-velocity for independent momentum flux calculation. The result showed that both the 72 h averaged upward flux and downward flux of zonal momentum were negative at nearly each height, meaning that the upward flux was dominated by westward propagating waves while the downward flux was dominated by eastward propagating waves. The magnitude of the downward flux was approximately a factor of 1.5 larger than the upward flux for waves in the 2~7 h and 7~24 h period bands, and about equal to the upward flux in the 10–30 min and 30 min–2 h period bands. It is also observed that the vertical flux of zonal momentum tended to be small in each frequency band at the altitudes below the jet maximum (10~12 km, and the flux increased toward more negative values to reach a negative maximum at some altitude well above the jet maximum. Daily averaged flux showed tremendous variation: The 1st 24 h (quiet day was relatively quiet, and the fluxes of the 2nd and 3rd 24 h (active days increased sharply. Moreover, the upward fluxes of zonal momentum below 17 km in the quiet day for each period band (10~30 min, 30 min~2 h, 2~7 h, and 7~24 h were dominantly positive, while the corresponding downward fluxes were dominantly negative, meaning that the zonal momentum below 17 km in each period band under study were dominantly eastward (propagating along the mean wind. In the active days, both the upward fluxes and downward fluxes in each frequency band were dominantly negative throughout the whole altitude range 6.1–18.95 km.

    Electroencephalographic studies of subjects with autism spectrum disorders (ASD) provide evidences of brain functional aspects in this pathology. Mu rhythm can be reactive in normal population (mu suppression) to both self-movements and to movements performed by others. These reactivities are considered to be related to mirror neurons activity. Subjects with ASD show significant mu suppression to self-movements but they fail to react to the movements performed by others. These findings support the hypothesis of a dysfunctional mirror neurons system in individuals with ASD. Moreover, dysfunction of mirror neurons would be related to social and communicative impairments, cognitive deficits and impairment imitation skills associated with ASD.

    MuSR measurements in zero field were performed in ZrMn 2 and ZrMn 2 H 3.2 . The results confirm the existence in the hydride of a sluggish, spin-glass type magnetic transition. The dependence on temperature of the asymmetry of the muon disintegration shows that magnetic ordering begins to take place around 180 K, and suggests the existence of clusters of ordered Mn moments. Relaxation effects attributed to fluctuations of clustered magnetic moments are observed in the range 100 K-190 K

    2008-04-22

    In this thesis, the discovery potential of the ATLAS experiment at the Large Hadron Collider (LHC) at CERN for the heavy neutral Higgs bosons H/A of theMinimal Supersymmetric extension of the Standard Model of particle physics (MSSM) in the decay channels H/A{yields}{tau}{sup +}{tau}{sup -}{yields}e/{mu}+X and H/A{yields}{mu}{sup +}{mu}{sup -} has been studied. The ATLAS detector is designed to study the full spectrum of the physics phenomena occuring in the proton-proton collisions at 14 TeV center-of-mass energy and to provide answers to the question of the origin of particle masses and of electroweak symmetry breaking. For the studies, the ATLAS muon spectrometer plays an important role. The spectrometer allows for a precise muon momentum measurement independently of other ATLAS subdetectors. The performance of the muon spectrometer depends strongly on the performance of the muon tracking detectors, the Monitored Drift Tube Chambers (MDT). Computer programs have been developed in order to test and verify the ATLAS muon spectrometer simulation, an essential ingredient for data analysis. In addition, dedicated programs for the monitoring of the quality of the data collected by the muon spectrometer have been developed and tested with data from cosmic ray muons. High-quality cosmic ray muon data have been used for the calibration of the MDT-chambers. A new calibration method, called analytical autocalibration, has been tested. The proposed method achieved the required accuracy of 20 {mu}m in the determination of the space-to-drift-time relationship of the drift tubes of the MDT chambers with only 2000 muon tracks per chamber. Reliable muon detector simulation and calibration are essential for the study of the MSSM Higgs boson decays H/A{yields}{tau}{sup +}{tau}{sup -}{yields}e/{mu}+X and H/A{yields}{mu}{sup +}{mu}{sup -} and of the corresponding background processes. The signal selection and background rejection requirements have been optimized for maximum signal

    We study the radiative leptonic decay, B{sup -}{yields}{mu}{sup -}{nu}{sub {mu}}{gamma}, in the framework of a relativistic independent quark model, based on the confining potential in the scalar-vector harmonic form. As expected, we find that the photon emission in this decay overcomes the so-called helicity suppression inevitable in the case of pure leptonic decay (B{sup -}{yields}{mu}{sup -}{nu}{sub {mu}}). Our result for the branching ratio is Br(B{sup -}{yields}{mu}{sup -}{nu}{sub {mu}}{gamma})=1.70x10{sup -6}, which is comparable with other model predictions within the current experimental upper limit. The photon energy spectrum predicted in the model is slightly asymmetric with the peak value around 1.45 GeV, which should render it quite accessible to experimental analysis.

  14. Performance study of single undoped CsI crystals for the Mu2e experiment

    2016-01-01

    The Mu2e experiment at Fermilab aims to measure the neutrinoless muon-to-electron conversion, which is a charged-lepton flavor-violating process. The goal of the experiment is to reach a single event sensitivity of 2.5 × 10"−"1"7, to set an upper limit on the muon conversion rate at 6.7 × 10"−"1"7 in a three-year run. For this purpose, the Mu2e detector is designed to identify electrons from muon conversion and reduce the background to a negligible level. It consists of a low-mass straw tracker and a pure CsI crystal calorimeter. In this paper, the performance of undoped CsI single crystal is reported. Crystals from many vendors have been characterized by determining their Light Yield (LY) and Longitudinal Response Uniformity (LRU), when read with a UV extended PMT, and their time resolution when coupled to a silicon photomultiplier. The crystals show a LY of ∼ 100 photoelectrons per MeV when wrapped with Tyvek and coupled to the PMT without optical grease. The LRU is well represented by a linear slope that is on average 0.6%/cm. Both measurements have been performed using a "2"2Na source. The timing performance has been evaluated exploiting cosmic rays, with MPPC readout. A timing resolution lower than 400 ps has been achieved (at ∼ 20 MeV, which is the energy released by a minimum ionizing particle in the crystal).

    Micro Proton Induced X-ray Emission ({mu}-PIXE) analysis has been employed herein in investigating and quantifying the distribution of a number of essential elements in thin human diseased articular cartilage sections affected by osteoarthritis (OA). Various cations Ca, P and Zn have been reported to play an important role both in the normal growth and remodelling of articular cartilage and subchondral bone as well as in the degenerative and inflammatory processes associated with the disease; they act as co-factors of a class of enzymes known as metalloproteinases which are believed to be active during the initiation, progress and remodelling processes associated with osteoarthritis. Other important enzymes such as alkaline phosphatase are associated with cartilage mineralization. Synchrotron radiation X-ray fluorescence (SR-XRF) for mapping of elemental distributions in bone and cartilage has also been employed by the present group and others. In the current investigations using the cSAXS beamline at the Swiss light source, Small-Angle X-ray Scattering (SAXS) was carried out on decalcified human articular cartilage to explore the structural and organizational changes of collagen networks in diseased articular cartilage.

    The pleasant effects of food and alcohol intake are partially mediated by mu-opiate receptors in the ventral striatum, a central area of the brain reward system. Blockade of mu-opiate receptors with naltrexone reduces the relapse risk among some but not all alcoholic individuals. To test the hypothesis that alcohol craving is pronounced among alcoholic individuals with a high availability of mu-opiate receptors in the brain reward system. Patients and comparison sample. The availability of central mu-opiate receptors was measured in vivo with positron emission tomography (PET) and the radioligand carbon 11-labeled carfentanil in the ventral striatum and compared with the severity of alcohol craving as assessed by the Obsessive Compulsive Drinking Scale (OCDS). Hospitalized care. Volunteer sample of 25 male alcohol-dependent inpatients assessed after detoxification of whom 12 underwent PET again 5 weeks later. Control group of 10 healthy men. After 1 to 3 weeks of abstinence, the availability of mu-opiate receptors in the ventral striatum, including the nucleus accumbens, was significantly elevated in alcoholic patients compared with healthy controls and remained elevated when 12 alcoholic patients had these levels measured 5 weeks later (P<.05 corrected for multiple testing). Higher availability of mu-opiate receptors in this brain area correlated significantly with the intensity of alcohol craving as assessed by the OCDS. Abstinent alcoholic patients displayed an increase in mu-opiate receptors in the ventral striatum, including the nucleus accumbens, which correlated with the severity of alcohol craving. These findings point to a neuronal correlate of alcohol urges.

    We present the results of recent {mu}SR experiments on a variety of novel organic and molecular magnetic systems. Muons are sensitive to local static fields and magnetic fluctuations, but can probe much more than just the onset of long-range magnetic order. We review our work on nitronyl nitroxide organic ferromagnets and antiferromagnets. We describe a muon study of the spin-crossover phenomenon which has been studied in Fe(PM-PEA){sub 2}(NCS){sub 2}, and which shows Gaussian and root-exponential muon relaxation in the high-spin and low-spin phases, respectively. Experiments on a disc-shaped molecular complex containing Fe{sub 19} (with spin ((31)/(2))) reveal the effects of quantum tunneling of magnetization and allow an estimate of the quantum tunneling rate.

    The aim of this study was to evaluate and compare the tensile bond strength of a composite resin adhered to the enamel and dentin which have received superficial irradiation with an Er:YAG laser (2.94 {mu}m) or with CO{sub 2} laser ( 9.6 {mu}m) and later on etched with the phosphoric acid at 35%. After the use of the adhesive system, resin cones were made on the etched surfaces by both lasers and tensile bond strength tests were performed. All samples were observed at the SEM - there was an increase of the degree of fusion and resolidification in the irradiated enamel and dentin samples with the CO{sub 2} laser (9.6 {mu}m), creating a vitrified layer with tiny craters. With the Er:YAG laser (2.94 {mu}m) there were typical morphological explosive microablation with the exposition of the tubules in the dentin.The surface acquired by the association of the CO{sub 2} laser ( 9.6 {mu}m) plus acid etching no longer presented the aspect of fusion being this layer completely removed. There were statistical significant differences among ali three methods of etching in the treatment of the enamel and dentin surface. The tensile bond strength test showed that etching of these enamel and dentin surfaces with acid exclusively (control group) presented great values, surpassing the values of the etching acquired with the Er:YAG laser (2.94 {mu}) plus acid or the CO{sub 2} laser (9.6 {mu}m) plus acid. With the parameters used in this experiment the Er:YAG laser (2.94 {mu}m) showed to be more effective than the CO{sub 2} laser (9.6 {mu}m) for the hard dental surfaces etching procedure. (author)

    2016-01-01

    The nucleus "2"3"5"mU is an isomer with extremely low excitation energy (76.8 eV) and decays dominantly through the internal conversion (IC) process. Because outer-shell electrons are involved in the IC process, the decay constant of "2"3"5"mU depends on its chemical environment. We plan to study the deexcitation process of "2"3"5"mU by measuring the energy spectra of IC electrons in addition to the decay constants for various chemical forms. In this paper, the preparation method of "2"3"5"mU samples from "2"3"9Pu by using alpha-recoil energy is reported. A Collection Apparatus for Recoil Products was fabricated, and then collection efficiencies under various conditions were determined by collecting "2"2"4Ra recoiling out of "2"2"8Th electrodeposited and precipitated sources. The pressure in the apparatus (vacuum or 1 atm of N_2 gas) affected the variations of the collection efficiencies depending on the negative voltage applied to the collector. The maximum values of the collection efficiencies were mainly affected by the thickness of the "2"2"8Th sources. From these results, the suitable conditions of the "2"3"9Pu sources for preparation of "2"3"5"mU were determined. In addition, dissolution efficiencies were determined by washing collected "2"2"4Ra with solutions. When "2"2"4Ra was collected in 1 atm of N_2 gas and dissolved with polar solutions such as water, the dissolution efficiencies were nearly 100%. The method of rapid dissolution of recoil products would be applicable to rapid preparation of short-lived "2"3"5"mU samples for various chemical forms.

    A potent {mu}-opioid agonist, ({sup 11}C)carfentanil, was prepared by the methylation of carfentanil carboxylic acid with ({sup 11}C)methyl iodide in order to study brain {mu}-opioid receptors by positron emission tomography. Synthesis (including purification) was completed within 25 min and the radiochemical yield was approximately 40%. The radiochemical purity of the product was more than 99% and its specific activity was 3.7-7.4 GBq/{mu}mol. Biodistribution studies performed in mice after intravenous injection showed a high brain uptake and rapid blood clearance, so a high brain/blood ratio of 1.5-1.8 was found from 5 to 30 min. Regional cerebral distribution studies in the mouse showed a significantly higher uptake of ({sup 11}C)carfentanil by the thalamus and striatum than by the cerebellum, with the radioactivity in the striatum disappearing more rapidly than that in the thalamus. Treatment with naloxone significantly reduced the uptake of ({sup 11}C)carfentanil by the thalamus and striatum. These results indicate that ({sup 11}C)carfentanil binds specifically to brain {mu}-opioid receptors. (author).

  6. B^0_s -> mu^+ mu^- gamma decay in LHCb

    CERN Multimedia

    Dettori, F

    2009-01-01

    Being FCNC processes, the B^0_s -> mu^+ mu^- and B^0_s -> mu^+ mu^- gamma decays are suppressed in the Standard Model, but can be highly enhanced in case of New Physics which can come as new particles flowing in the loops. Both these decays occur with a branching ratio in the SM at the level of 10?9: the Bs -> mu^+ mu^- gamma in fact is suppressed by having one more vertex but enhanced by removing the elicity suppression. Prospects for the search of the B^0_s -> mu^+ mu^- gamma decay in LHCb are presented in this poster.

    A search for the decays $B^0_s \\to \\mu^+ \\mu^-$ and $B^0 \\to \\mu^+ \\mu^-$ is performed with 0.37 fb$^{-1}$ of $pp$ collisions at $\\sqrt{s}$ = 7~TeV collected by the LHCb experiment in 2011. The upper limits on the branching fractions are ${\\cal B} (B^0_s \\to \\mu^+ \\mu^-) < 1.6 \\times 10^{-8}$ and ${\\cal B}(B^0 \\to \\mu^+ \\mu^-) <3.6 \\times 10^{-9}$ at 95% confidence level. A combination of these results with the LHCb limits obtained with the 2010 dataset leads to ${\\cal B} (B^0_s \\to \\mu^+ \\mu^-) <1.4 \\times 10^{-8}$ and ${\\cal B} (B^0 \\to \\mu^+ \\mu^-) <3.2 \\times 10^{-9}$ at 95% confidence level.

    Full Text Available Objective: To determine whether changes in sensorimotor control resulting from speaking conditions that induce fluency in people who stutter (PWS can be measured using electroencephalographic (EEG mu rhythms in neurotypical speakers.Methods: Non-stuttering (NS adults spoke in one control condition (solo speaking and four experimental conditions (choral speech, delayed auditory feedback (DAF, prolonged speech and pseudostuttering. Independent component analysis (ICA was used to identify sensorimotor μ components from EEG recordings. Time-frequency analyses measured μ-alpha (8–13 Hz and μ-beta (15–25 Hz event-related synchronization (ERS and desynchronization (ERD during each speech condition.Results: 19/24 participants contributed μ components. Relative to the control condition, the choral and DAF conditions elicited increases in μ-alpha ERD in the right hemisphere. In the pseudostuttering condition, increases in μ-beta ERD were observed in the left hemisphere. No differences were present between the prolonged speech and control conditions.Conclusions: Differences observed in the experimental conditions are thought to reflect sensorimotor control changes. Increases in right hemisphere μ-alpha ERD likely reflect increased reliance on auditory information, including auditory feedback, during the choral and DAF conditions. In the left hemisphere, increases in μ-beta ERD during pseudostuttering may have resulted from the different movement characteristics of this task compared with the solo speaking task. Relationships to findings in stuttering are discussed.Significance: Changes in sensorimotor control related feedforward and feedback control in fluency-enhancing speech manipulations can be measured using time-frequency decompositions of EEG μ rhythms in neurotypical speakers. This quiet, non-invasive, and temporally sensitive technique may be applied to learn more about normal sensorimotor control and fluency enhancement in PWS.

    A {mu}SR study of the temperature dependence of the London penetration depth {lambda} in sintered samples of YBa{sub 2}Cu{sub 3}O{sub x} (with various oxygen contents x), YBa{sub 2}Cu{sub 4}O{sub 8} and Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8} is presented. It is found that the temperature behavior of {lambda} of all these cuprate superconductors is consistent with conventional s-wave pairing. However, there are significant differences concerning the exact temperature dependence of {lambda} in these materials. In YBa{sub 2}Cu{sub 3}O{sub x} with high x, the behavior of {lambda}(T) is well described by the two-fluid model (strong coupling), whereas {lambda}(T) in YBa{sub 2}Cu{sub 3}O{sub x} with low x, YBa{sub 2}Cu{sub 4}O{sub 8} and Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8} is in better agreement with weak-coupling BCS theory. Possible reasons for the different temperature behavior of {lambda} in these materials are discussed. (orig.).

    The authors report the results of an experimental investigation on the properties of the ( mu He)/sub 2S//sup +/ metastable muonic system, which was performed stopping negative muons in a pure helium target at pressures ranging from 10 to 50 atm, and observing the total yield and the differential time distribution of the X-rays released in delayed coincidence with the arrival of muons. At each pressure P, information was obtained on the following quantities: a) the total disappearance rate lambda /sub 2S, tot/(P) of the ( mu He)/sub 2S//sup +/ system, b) the disappearance rates lambda /sub A/(P) and lambda /sub St/(P) of the ( mu He)/sub 2S//sup +/ system for external Auger effect and Stark-mixing collisions.

  11. Studies of Nu-mu to Nu-e Oscillation Appearance in the MINOS Experiment

    Energy Technology Data Exchange (ETDEWEB)

    The MINOS experiment uses a long baseline neutrino beam, measured 1 km downstream from its origin in the Near Detector at Fermilab, and 734 km later in the large underground Far Detector in the Soudan mine. By comparing these two measurements, MINOS can probe the atmospheric domain of the neutrino oscillation phenomenology with unprecedented precision. Besides the ability to perform a world leading determination of the Δm$2\\atop{23}$ and θ23 parameters, via vμ flux disappearance, MINOS has the potential to make a leading measurement of vμ → ve oscillations in the atmospheric sector by looking for ve appearance at the Far Detector. The observation of ve appearance, tantamount to establishing a non-zero value of the θ13 mixing angle, opens the way to studies of CP violation in the leptonic sector, the neutrino spectral mass pattern ordering and neutrino oscillations in matter, the driving motivations of the next generation of neutrino experiments. In this thesis, we study the MINOS potential for measuring θ13 in the context of the MINOS Mock Data Challenge using a multivariate discriminant analysis method. We show the method's validity in the application to ve event classification and background identification, as well as in its ability to identify a ve signal in a Mock Data sample generated with undisclosed parameters. An independent shower reconstruction method based on three-dimensional hit matching and clustering was developed, providing several useful discriminator variables used in the multivariate analysis method. We also demonstrate that within 2 years of running, MINOS has the potential to improve the current best limit on θ13, from the CHOOZ experiment, by a factor of 2.

    A search for the decays $B_{s}^{0}\\to\\mu^+\\mu^-$ and $B^{0}\\to\\mu^+\\mu^-$ is performed with about 37 pb$^{-1}$ of $pp$ collisions at $\\sqrt{s}$ = 7 TeV collected by the LHCb experiment at the Large Hadron Collider at CERN. The observed numbers of events are consistent with the background expectations. The resulting upper limits on the branching ratios are $B(B_{s}^{0}\\to\\mu^+\\mu^-) < 5.6 \\times 10^{-8}$ and $B(B^{0}\\to\\mu^+\\mu^-) < 1.5 \\times 10^{-8}$ at 95% confidence level.

    Full Text Available Abstract Background Mu opioid receptors have previously been shown to be altered in people with affective disorders who died as a result of suicide. We wished to determine whether these changes were more widespread and independent of psychiatric diagnoses. Methods Mu receptor levels were determined using [3 H]DAMGO binding in BA24 from 51 control subjects; 38 people with schizophrenia (12 suicides; 20 people with major depressive disorder (15 suicides; 13 people with bipolar disorder (5 suicides and 9 people who had no history of psychiatric disorders but who died as a result of suicide. Mu receptor levels were further determined in BA9 and caudate-putamen from 38 people with schizophrenia and 20 control subjects using [3 H]DAMGO binding and, in all three regions, using Western blots. Data was analysed using one-way ANOVAs with Bonferroni’s Multiple Comparison Test or, where data either didn’t approximate to a binomial distribution or the sample size was too small to determine distribution, a Kruskal-Wallis test with Dunn’s Multiple Comparison Test. Results [3 H]DAMGO binding density was lower in people who had died as a result of suicide (p3 H]DAMGO binding densities, but not mu protein levels, were significantly decreased in BA9 from people with schizophrenia who died as a result of suicide (p Conclusions Overall these data suggest that mu opioid receptor availability is decreased in the brains of people with schizophrenia who died as a result of suicide, which would be consistent with increased levels of endogenous ligands occupying these receptors.

    The angular distribution and differential branching fraction of the decay $B^+ \\to K^+ \\mu^+\\mu^-$ are studied with a dataset corresponding to 1.0 fb$^{-1}$ of integrated luminosity, collected by the LHCb experiment. The angular distribution is measured in bins of dimuon invariant mass squared and found to be consistent with Standard Model expectations. Integrating the differential branching fraction over the full dimuon invariant mass range yields a total branching fraction of $B(B^+ \\to K^+ \\mu^+\\mu^-) = (4.36 ± 0.15 ± 0.18) \\times 10^{−7}$. These measurements are the most precise to date of the $B^+ \\to K^+ \\mu^+\\mu^-$ decay.

    We perform a study of the standard model fit to the mixing quantities {Delta}M{sub B{sub s}}, and {Delta}{Lambda}{sub B{sub s}}/{Delta}M{sub B{sub s}} in order to bound contributions of new physics (NP) to B{sub s} mixing. We then use this to explore the branching fraction of B{sub s} {yields} {mu}{sup +}{mu}{sup -} in certain models of NP. In most cases, this constrains NP amplitudes for B{sub s} {yields} {mu}{sup +}{mu}{sup -} to lie below the standard model component.

    In 0.26 ..mu..m wavelength laser experiments that were performed in planar geometry with irradiances between 10/sup 13/ and 10/sup 15/ W/cm/sup 2/, the ablation pressure and the target velocity have been measured using a shock-velocity measurement and the double foil technique, respectively. The conditions are discussed that must be satisfied if the double-foil technique is to give an accurate measurement of the velocity of the dense part of the target. The rocket model has also been improved using a time-dependent applied pressure pulse, in order to accurately describe the relation between ablation pressure, target velocity, and ablated fraction. Pressures up to 50 Mbar have been easily generated since lateral energy transport is rather low with a 0.26 ..mu..m wavelength laser.

    Oxidative processes have the ability to influence mu-calpain activity. In the present study the influence of oxidation on activity and autolysis of mu-calpain was examined. Furthermore, LC-MS/MS analysis was employed to identify and characterize protein modifications caused by oxidation. The results revealed that the activity of mu-calpain is diminished by oxidation with H2O2 in a reversible manner involving cysteine and that the rate of autolysis of mu-calpain concomitantly slowed. The LC-MS/MS analysis of the oxidized mu-calpain revealed that the amino acid residues 105-133 contained a disulfide bond between Cys(108) and Cys(115). The finding that the active site cysteine in mu-calpain is able to form a disulfide bond has, to our knowledge, not been reported before. This could be part of a unique oxidation mechanism for mu-calpain. The results also showed that the formation of the disulfide bond is limited in the control (no oxidant added), and further limited in a concentration-dependent manner when beta-mercaptoethanol is added. However, the disulfide bond is still present to some extent in all conditions indicating that the active site cysteine is potentially highly susceptible to the formation of this intramolecular disulfide bond.

    Regulation of axonal fasciculation plays an important role in the precise patterning of neural circuits. Selective fasciculation contributes to the sorting of different types of axons and prevents the misrouting of axons. However, axons must defasciculate once they reach the target area. To study the regulation of fasciculation, we focused on the primary vestibulo-cerebellar afferents (PVAs), which show a dramatic change from fasciculated axon bundles to defasciculated individual axons at their target region, the cerebellar primordium. To understand how fasciculation and defasciculation are regulated in this system, we investigated the roles of murine SC1-related protein (MuSC), a molecule belonging to the immunoglobulin superfamily. We show: (i) by comparing 1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate (Dil) labelling and anti-MuSC immunohistochemistry, that downregulation of MuSC in PVAs during development is concomitant with the defasciculation of PVA axons; (ii) in a binding assay with cells expressing MuSC, that MuSC has cell-adhesive activity via a homophilic binding mechanism, and this activity is increased by multimerization; and (iii) that MuSC also displays neurite outgrowth-promoting activity in vestibular ganglion cultures. These findings suggest that MuSC is involved in axonal fasciculation and its downregulation may help to initiate the defasciculation of PVAs.

  8. Studies of the Impact of Magnetic Field Uncertainties on Physics Parameters of the Mu2e Experiment

    The Mu2e experiment at Fermilab will search for a signature of charged lepton flavor violation, an effect prohibitively too small to be observed within the Standard Model of particle physics. Therefore, its observation is a signal of new physics. The signature that Mu2e will search for is the ratio of the rate of neutrinoless coherent conversion of muons into electrons in the field of a nucleus, relative to the muon capture rate by the nucleus. The conversion process is an example of charged lepton flavor violation. This experiment aims at a sensitivity of four orders of magnitude higher than previous related experiments. The desired sensitivity implies highly demanding requirements of accuracy in the design and conduct of the experiment. It is therefore important to investigate the tolerance of the experiment to instrumental uncertainties and provide specifications that the design and construction must meet. This is the core of the work reported in this thesis. The design of the experiment is based on three superconducting solenoid magnets. The most important uncertainties in the magnetic field of the solenoids can arise from misalignments of the Transport Solenoid, which transfers the beam from the muon production area to the detector area and eliminates beam-originating backgrounds. In this thesis, the field uncertainties induced by possible misalignments and their impact on the physics parameters of the experiment are examined. The physics parameters include the muon and pion stopping rates and the scattering of beam electrons off the capture target, which determine the signal, intrinsic background and late-arriving background yields, respectively. Additionally, a possible test of the Transport Solenoid alignment with low momentum electrons is examined, as an alternative option to measure its field with conventional probes, which is technically difficult due to mechanical interference. Misalignments of the Transport Solenoid were simulated using standard

    The present study utilized a newly developed quantitative immunohistochemical assay to measure changes in {mu} opioid receptor abundance following chronic administration of the opioid receptor antagonist naltrexone. These data were compared with those obtained from {mu} receptor radioligand binding on adjacent tissue sections, in order to determine whether the characteristic antagonist-induced increase in radioligand binding is due to an increase in the total number of {mu} receptors and/or to an increase in the proportion of receptors that are in an active binding conformation in the absence of a change in the total number of receptors. Adult male Sprague-Dawley rats were administered naltrexone, 7-8 mg/kg per day, or saline continuously for seven days by osmotic minipumps, after which time their brains were processed for immunohistochemistry and receptor autoradiography on adjacent fresh frozen tissue sections. Semiquantitative immunohistochemistry was performed using a radiolabelled secondary antibody for autoradiographic determination and a set of radioactive standards. Results demonstrate an overall concordance between the distribution of {mu} opioid receptors as measured by the two different methods with a few exceptions. Following naltrexone administration, {mu} receptor immunoreactivity was significantly higher in the amygdala, thalamus, hippocampus, and interpeduncular nucleus as compared with the saline-treated control animals. [{sup 3}H]D-Ala{sup 2},N-Me-Phe{sup 4},Gly-ol{sup 5}-enkephalin binding to {mu} opioid receptors was significantly higher in the globus pallidus, amygdala, thalamus, hypothalamus, hippocampus, substantia nigra, ventral tegmental area, central gray, and interpeduncular nucleus of the naltrexone-treated rats.These findings indicate that in some brain regions chronic naltrexone exposure increases the total number of {mu} opioid receptors, while in other regions there is an increase in the percent of active receptors without an

    A search for $B^0_s \\to \\mu+ \\mu^-$ and $B^0 \\to \\mu^+ \\mu^-$ decays is performed using $1.0$ fb$^{-1}$ of $pp$ collision data collected at $\\sqrt{s}=7$\\,TeV with the LHCb experiment at the Large Hadron Collider. For both decays the number of observed events is consistent with expectation from background and Standard Model signal predictions. Upper limits on the branching fractions are determined to be $BR(B^0_s \\to \\mu^+ \\mu^-)< 4.5 \\,(3.8) \\times 10^{-9}$ and $BR(B^0 \\to \\mu^+ \\mu^-) $<1.0\\, (0.81) \\times 10^{-9}$ at 95\\,\\% (90\\,\\%) confidence level.

    The flavour changing neutral current decays can be interesting probes for searching for new physics. Angular distributions of $b \\to s \\ell^+ \\ell^-$ transition processes of both $\\mathrm{B}^0 \\to \\mathrm{K}^{*0} \\mu^ +\\mu^-$ and $\\mathrm{B}^{+} \\to \\mathrm{K}^{+} \\mu^+\\mu^-$ are studied using a sample of proton-proton collisions at $\\sqrt{s} = 8~\\mathrm{TeV}$ collected with the CMS detector at the LHC, corresponding to an integrated luminosity of $20.5~\\mathrm{fb}^{-1}$. Angular analyses are performed to determine $P_1$ and $P_5'$ angular parameters for $\\mathrm{B}^0 \\to \\mathrm{K}^{*0} \\mu^ +\\mu^-$ and $A_{FB}$ and $F_{H}$ parameters for $\\mathrm{B}^{+} \\to \\mathrm{K}^{+} \\mu^+\\mu^-$, all as functions of the dimuon invariant mass squared. The $P_5'$ parameter is of particular interest due to recent measurements that indicate a potential discrepancy with the standard model. All the measurements are consistent with the standard model predictions. Efforts with more channels and more coming data will be con...

  14. {mu}-XRF/{mu}-RS vs. SR {mu}-XRD for pigment identification in illuminated manuscripts

    Energy Technology Data Exchange (ETDEWEB)

    For the non-destructive identification of pigments and colorants in works of art, in archaeological and in forensic materials, a wide range of analytical techniques can be used. Bearing in mind that every method holds particular limitations, two complementary spectroscopic techniques, namely confocal {mu}-Raman spectroscopy ({mu}-RS) and {mu}-X-ray fluorescence spectroscopy ({mu}-XRF), were joined in one instrument. The combined {mu}-XRF and {mu}-RS device, called PRAXIS unites both complementary techniques in one mobile setup, which allows {mu}- and in situ analysis. {mu}-XRF allows one to collect elemental and spatially-resolved information in a non-destructive way on major and minor constituents of a variety of materials. However, the main disadvantages of {mu}-XRF are the penetration depth of the X-rays and the fact that only elements and not specific molecular combinations of elements can be detected. As a result {mu}-XRF is often not specific enough to identify the pigments within complex mixtures. Confocal Raman microscopy ({mu}-RS) can offer a surplus as molecular information can be obtained from single pigment grains. However, in some cases the presence of a strong fluorescence background limits the applicability. In this paper, the concrete analytical possibilities of the combined PRAXIS device are evaluated by comparing the results on an illuminated sheet of parchment with the analytical information supplied by synchrotron radiation {mu}-X-ray diffraction (SR {mu}-XRD), a highly specific technique.

  15. MuPAD tutorial

    CERN Document Server

    Creutzig, Christopher

    2004-01-01

    This book explains the basic use of the software package called MuPAD and gives an insight into the power of the system. MuPAD is a so-called com­ puter algebra system, which is developed mainly by Sciface Software and the MuPAD Research Group of the University of Paderborn in Germany. This introduction addresses mathematicians, engineers, computer scientists, natural scientists and, more generally, all those in need of mathematical com­ putations for their education or their profession. Generally speaking, this book addresses anybody who wants to use the power of a modern computer algebra package. There are two ways to use a computer algebra system. On the one hand, you may use the mathematical knowledge it incorporates by calling system functions interactively. For example, you can compute symbolic integrals or generate and invert matrices by calling appropriate functions. They comprise the system's mathematical intelligence and may implement sophisticated al­ gorithms. Chapters 2 through 15 discuss this...

    A numerical study of a triode gun with a very small cathode-grid distance (150 {mu}m) which allows to evaluate with great accuracy the effect of the grid and of the temperature on the final beam emittance is presented. The simulation uses a modified version of the bidimensional code EGUN for PC that simulates the grid with a set of concentric rings and allows to define several regions of different mesh size, providing the way to connect results between adjacent regions. The calculation procedure is described in detail together with the results of the simulation for different values of the grid potential.

    At the new DC muon beamline MuSIC at Research Center for Nuclear Physics (RCNP), Osaka University, the beamline construction from the solenoid system of the muon production to the experimental port was completed. A beamline commissioning and a feasibility study for μSR are now in progress. With newly refurbished spectrometer installed at the experimental port, we succeeded in observing μSR spectra and μ-e decay asymmetry in a simple setup down to 4 K. We are still under development of other μSR appratuses.

  19. Control room habitability study - findings and recommendations

    International Nuclear Information System (INIS)

    Driscoll, J.W.

    1987-01-01

    The Advisory Committee on Reactor Safeguards (ACRS) has raised a number of concerns related to control room habitability and has recommended actions which they believe could alleviate these concerns. As a result of the ACRS's concerns, the US Nuclear Regulatory Commission's (NRC) Office of Nuclear Reactor Regulation (NRR) in conjunction with the Offices of Research and Inspection and Enforcement, and the NRC regional offices, embarked upon a program to reevaluate Control Room Habitability. Argonne National Laboratory was contracted by the NRC to perform a Control Room Habitability Study on twelve licensed power reactors. The plants selected for the study were chosen based upon architect engineer, nuclear steam system supplier, utility, and plant location. The major findings of this study are included in this report along with generic recommendations of the review team that apply to control room HVAC systems. Although the study is not complete, at the time of publication of this report, the results obtained to date should be useful to persons responsible for Control Room Habitability in evaluating their own systems

    The Advisory Committee on Reactor Safeguards (ACRS) has raised a number of concerns related to control room habitability and has recommended actions which they believe could alleviate these concerns. As a result of the ACRS's concerns, the US Nuclear Regulatory Commission's (NRC) Office of Nuclear Reactor Regulation (NRR) in conjunction with the Offices of Research and Inspection and Enforcement, and the NRC regional offices, embarked upon a program to reevaluate Control Room Habitability. Argonne National Laboratory was contracted by the NRC to perform a Control Room Habitability Study on twelve licensed power reactors. The plants selected for the study were chosen based upon architect engineer, nuclear steam system supplier, utility, and plant location. Participants in the study review the plant design as contained in the Updated Safety Analysis Report, Technical Specifications, Three Mile Island action item III.D.3.4 submittal on Control Room Habitability, NRC staff evaluation of the III.D.3.4 submittal, appropriate plant operating procedures, system drawings, and significant Licensee Event Reports on Loss of Cooling to the Control Room Envelope. A two-day visit is then made to the plant to determine if the as-built systems are built, operated, and surveillance performed as described in the documentation reviewed prior to the visit. The major findings of this study are included in this report along with generic recommendations of the review team that apply to control room HVAC systems. Although the study is not complete, at the time of publication of this report, the results obtained to date should be useful to persons responsible for Control Room Habitability in evaluating their own systems

    The tau /sup -/ to mu /sup -/ nu /sub mu / nu /sub tau / branching ratio has been measured using data collected from 1990 to 1995 by the OPAL detector at the LEP collider. The resulting value of B( tau /sup -/ to mu /sup -/ nu /sub mu / nu /sub tau /) = 0.1734 +or- 0.0009 (stat) +or- 0.0006(syst) has been used in conjunction with other OPAL measurements to test lepton universality, yielding the coupling constant ratios g/sub mu //g/sub e/ = 1.0005 +or- 0.0044 and g/sub tau //g/sub e/ = 1.0031 +or- 0.0048, in good agreement with the Standard Model prediction of unity. A value for the Michel parameter eta = 0.004 +or- 0.037 has also been determined and used to find a limit for the mass of the charged Higgs boson, m/sub H/+or- > 1.28 tan beta , in the minimal supersymmetric standard model.

    Stimulated Raman pumping (SRP) is used to produce H 2 in its first vibrational state, in order to measure, for the first time, the Mu+H 2 *(v=1)→MuH+H reaction rate at room temperature, as a prototypical example of new directions in gas-phase muonium chemistry, utilizing the pulsed muon beam and a new dedicated laser system at the RIKEN/RAL Laboratory. Reported here is a preliminary result but the final results are expected to provide definitive new tests of reaction rate theory on the highly accurate H 3 potential energy surface. The major difficulty in this experiment, compared to the standard SRP process, is to ensure a homogeneous excitation over a volume of several cm 3 and of sufficient intensity to ensure a measurable Mu relaxation rate. The techniques used to accomplish this are described. The experiment utilizes the 2nd harmonic output of a Nd:YAG laser (532 nm) with pulse energies up to 500 mJ at a repetition rate of 25 Hz. Different optical setups have been constructed and tested in order to optimize the number of laser-pumped H 2 molecules and their overlap with the stopping profile of the muon beam in the reaction cell (total volume ∼100x40x4mm 3 ). The first result of this experiment gives a measured relaxation rate due to laser excitation of λ*=0.085±0.051μs -1 , consistent with theory but limited by both low statistics and particularly a high background relaxation rate.

    A search for the rare decay $D^0 \\to \\mu^+ \\mu^-$is performed using a data sample, corresponding to an integrated luminosity of 0.9 fb$^{-1}$, of $pp$ collisions collected at a centre-of-mass energy of 7 TeV by the LHCb experiment. The observed number of events is consistent with the background expectations and corresponds to an upper limit of ${\\cal B}(D^0 \\to \\mu^+ \\mu^-) < 6.2(7.6) \\times 10^{-9}$ at 90% (95%) confidence level. This result represents an improvement of more than a factor twenty with respect to previous measurements.

    A search is performed for the lepton number violating decay $B^{+}\\rightarrow h^- \\mu^+ \\mu^+$, where $h^-$ represents a $K^-$ or a $\\pi^-$, using data from the LHCb detector corresponding to an integrated luminosity of $36pb^{-1}$. The decay is forbidden in the Standard Model but allowed in models with a Majorana neutrino. No signal is observed in either channel and limits of $B(B^{+} \\rightarrow K^- \\mu^+ \\mu^+) < 5.4\\times 10^{-8}$ and $B(B^{+} \\rightarrow \\pi^- \\mu^+ \\mu^+) < 5.8\\times 10^{-8}$ are set at the 95% confidence level. These improve the previous best limits by factors of 40 and 30, respectively.

    We propose a new experiment, Mu2e, to search for charged lepton flavor violation with unprecedented sensitivity. We will measure the ratio of the coherent neutrinoless conversion in the field of a nucleus of a negatively charged muon into an electron to the muon capture process: R{sub {mu}e} = {mu}{sup -} + A(Z,N) {yields} e{sup -} + A(Z,N)/{mu}{sup -} + A(Z,N) {yields} {nu}{sub {mu}} + A(Z-1, N), with a sensitivity R{sub {mu}e} {le} 6 x 10{sup -17} at 90% CL. This is almost a four order-of-magnitude improvement over the existing limit. The observation of such a process would be unambiguous evidence of physics beyond the Standard Model. Since the discovery of the muon in 1936, physicists have attempted to answer I.I. Rabi's famous question: 'Who ordered that?' Why is there a muon? What role does it play in the larger questions of why there are three families and flavors of quarks, leptons, and neutrinos? We know quarks mix through a mechanism described by the Cabbibo-Kobayashi-Maskawa matrix, which has been studied for forty years. Neutrino mixing has been observed in the last decade, but mixing among the family of charged leptons has never been seen. The current limits are of order 10{sup -11} - 10{sup -13} so the process is rare indeed. Why is such an experiment important and timely? A major motivation for experiments at the Large Hadron Collider (LHC) is the possible observation of supersymmetric particles in the TeV mass range. Many of these supersymmetric models predict a {mu}-e conversion signal at R{sub {mu}e} {approx} 10{sup -15}. We propose to search for {mu}-e conversion at a sensitivity that exceeds this by more than an order of magnitude. The LHC may not be able to conclusively distinguish among supersymmetric models, so Mu2e will provide invaluable information should the LHC observe a signal. In the case where the LHC finds no evidence of supersymmetry, or other beyond-the-standard-model physics, Mu2e will probe for new physics at mass

    The angular distributions of the rare decays $B^+ \\to K^+\\mu^+\\mu^-$ and $B^0 \\to K^0_{\\rm\\scriptscriptstyle S}\\mu^+\\mu^-$ are studied with data corresponding to 3$~$fb$^{-1}$ of integrated luminosity, collected in proton-proton collisions at 7 and 8$~$TeV centre-of-mass energies with the LHCb detector. The angular distribution is described by two parameters, $F_{\\rm H}$ and the forward-backward asymmetry of the dimuon system $A_{\\rm FB}$, which are determined in bins of the dimuon mass squared. The parameter $F_{\\rm H}$ is a measure of the contribution from (pseudo)scalar and tensor amplitudes to the decay width. The measurements of $A_{\\rm FB}$ and $F_{\\rm H}$ reported here are the most precise to date and are compatible with predictions from the Standard Model.

    Decays of the B0 and B0s mesons into two muons are extremely rare in the Standard Model as they occur only via helicity suppressed loop diagrams. Their amplitudes can be significantly different in many New Physics models, especially with an extended Higgs sector. Therefore, the search for these decays provides a sensitive probe of physics beyond the Standard Model. A search for the decays B0s ->mu+mu- and B0 ->mu+mu- is performed with about 37 pb-1 of pp collisions at sqrt(s) = 7TeV collected by the LHCb experiment at the Large Hadron Collider at CERN. The analysis relies mostly on control samples with minimal use of the simulation. The observed numbers of events are consistent with the background expectations. The resulting upper limits on the branching ratios are B(B0s->mu+mu-) < 56x10-9 and B(B0->mu+mu-) < 15x10-9 at 95% confidence level. The analysis is presented and prospects are also given for the coming run.

    This thesis was realized in collaboration with the "theory'' group and the "D0" group of IPNL. Within D0 we have worked on a component of the calibration of the detector's calorimeter : the intercalibration. Using the fact the physics is $\\phi$-symmetric in D0, we created and applied statistical methods for a relative calibration of the $\\phi$-symmetric parts of the calorimeter. Work on particle physics concerned the two Higgs doublet model. In such models leptonic number violation is possible : we have simulated the $H^0/A^0 \\to \\tau \\mu$ signal in order to study the discovery potential and the constraints on the coupling responsible for this decay.

The branching ratio was measured to be ${\\rm BR}=(9.62\\pm0.25)\\times 10^{-8}$. The form factor $W(z)$, where $z=(M_{\\mu\\mu}/M_K)^2$, was parameterized according to several models. In particular, the slope of the linear form factor $W(z)=W_0(1+\\delta z)$ was measured to be $\\delta=3.11\\pm0.57$. Upper limits of $2.9\\times 10^{-2}$ and $2.3\\times 10^{-2}$ on possible charge asymmetry and forward-backward asymmetry were established at 90% CL.

    AUTHOR|(INSPIRE)INSPIRE-00400160

    This dissertation documents a study of very rare $B$-meson decays at the LHCb experiment, using data taken during the first experiment run of the Large Hadron Collider (LHC) and during the second experiment run until September 2016. The LHCb experiment was designed to test the Standard Model of particle physics and to search for New Physics effects that go beyond the scope of the Standard Model through the decay of $b$ hadrons produced in high energy proton-proton collisions at the LHC. The measurements described in this dissertation are made using data samples of proton-proton collisions with integrated luminosities of 1.0, 2.0 and 1.4 fb$^{-1}$, collected at centre-of-mass energies of 7, 8 and 13 TeV, respectively. The branching fractions of the very rare $B^{0} \\to \\mu^{+} \\mu^{-}$ and $B_{s}^{0} \\to \\mu^{+} \\mu^{-}$ decays and the effective lifetime of $B_{s}^{0} \\to \\mu^{+} \\mu^{-}$ decays are precisely predicted by the Standard Model and are sensitive to effects from New Physics.

    A featfinding committee of the German Federal Parliament in July 1980 recommended to perform a ''risk-oriented study'' of the SNR-300, the German 300 MW fast breeder prototype reactor being under construction in Kalkar. The main aim of this study was to allow a comparative safety evaluation between the SNR-300 and a modern PWR, thus to prepare a basis for a political decision on the SNR-300. Methods and main results of the study are presented in this paper. In the first step of the risk analysis six groups of accidents have been identified which may initiate core destruction. These groups comprise all conceivable courses, potentially leading to core destruction. By reliability analyses, expected frequency of each group has been calculated. In the accident analysis potential failure modes of the reactor tank have been investigated. Core destruction may be accompanied by the release of significant amounts of mechanical energy. The primary coolant system of SNR-300 is designed to withstand mechanical energy releases up to 370 MJ. Design features make it possible to cool the molten core inside the reactor tank.

    Most radiative transfer studies place the cloud clearings responsible for the 5-mu m bright areas at pressure levels greater than 1.5 bar whereas the low-albedo clouds are placed at lower pressure levels, in the so-called ammonia cloud. If this picture is correct, and assuming that the strong vertical shear of the zonal wind detected by the Galileo Entry Probe exists at all latitudes in Jupiter, the bright areas at 5 mu m should drift faster than the dark clouds, which is not observed. At the Galileo Probe Entry latitude this can be explained by a wave, but this is not a likely explanation for all regions where the anticorrelation between 5-mu m brightness and red-nIR reflectivity is observed. Therefore, either the vertical zonal wind shears are not global or cloud clearings and dark clouds are located at the same pressure level. We have developed a multiple scattering radiative transfer code to model the limb-darkening at several jovian features derived from IRTF 4.8-mu m images, in order to retrieve information on the cloud levels. The limb darkening coefficients range from 1.4 at hot spots to 0.58 at the Equatorial Region. We also find that reflected light is dominant over thermal emission in the Equatorial Region, as already pointed out by other investigators. Preliminary results from our code tend to favor the idea that the ammonia cloud is a very high-albedo cloud with little influence on the contrast seen in the red and nIR and that a deeper cloud at P >1.5 bar can be responsible for the cloud clearings and for the low-albedo features simultaneously. This research was supported by the Comision Interministerial de Ciencia y Tecnologia under contract ESP96-0623.

  18. WA uranium find under detailed study

    International Nuclear Information System (INIS)

    1987-01-01

    Results of detailed geological surveys of CRA's Kintyre prospect in Western Australia have confirmed the presence of uranium in significant quantities with a number of features that make it promising for mining. The deposit is set in the remote Rudall River area, about 1,200 kilometres northeast of Perth. So far, probable ore reserves of 15,000 tonnes of U 3 O 8 and possible reserves of 15,000 tonnes have been identified and announced. Grades vary widely within a range of 1.5 to 4kg per tonne. The bulk of the ore body lies within 160 metres of the surface, which means it could be mined by open cut methods. The uranium mineralisation has been encountered in bands of pitchblende occurring as veins within the host rock. Current indications are that conventional acid/leach solvent extraction processes can be used to extract the uranium. The Kintyre deposit lies about 700 metres inside the northern boundary of Western Australia's Rudall River National Park. Exploration by CRA at the southern end of the park, in the vicinity of Mt. Cotton, has been halted temporarily. While the Kintyre geological results to date are most encouraging, studies are now being carried out to determine the commercial potential of the deposit

    AUTHOR|(SzGeCERN)655651; Vrba, Vaclav; Cerri, Alessandro; Palestini, Sandro

    Rare $B_s$ and $B_d$ meson decays into two muons are forbidden at the tree level of the Standard Model. They offer the opportunity to perform genuine probes of Yukawa interactions or Electroweak precision tests and play very important role to find signatures of physics beyond the Standard Model. A brief insight into the theoretical foundations of these decays is given in the introductory section, followed by a section with the ATLAS experiment description, none of which is directly a result of author's own work. The ATLAS Collaboration has been searching for $B_{(s)}^0 \\to \\mu^{+}\\mu^{-}$ decays using merged 2011 $\\sqrt{s} = 7$ TeV and 2012 $\\sqrt{s} = 8$ TeV Full Run I Data sample ($\\approx 25~fb^{-1}$). The analysis procedure has been firmly established and unblinding of the search region of $B_{(s)}^0 \\to \\mu^{+}\\mu^{-}$ is imminent. A sensitivity of the analysis to the $B_s^0 \\to \\mu^{+}\\mu^{-}$ signal is estimated to be $4.7~\\pm~1.0~\\sigma$. The description of the whole ATLAS $B_{(s)}^0 \\to \\mu^{+}\\mu^{-...

    We report on a search for B0(s) --> mu+ mu- and B0(d) --> mu + mu- decays in pp collisions at square root(s) = 1.96 TeV using 364 pb(-1) of data collected by the CDF II detector at the Fermilab Tevatron Collider. After applying all selection requirements, we observe no candidates inside the B0(s) or B0(d) mass windows. The resulting upper limits on the branching fractions are B(B0(s) --> mu+ mu-) mu+ mu-) < 3.9 x 10(-8) at 90% confidence level.

  1. EEG Mu Rhythm and Imitation Impairments in Individuals with Autism Spectrum Disorder

    Imitation ability has consistently been shown to be impaired in individuals with autism. A dysfunctional execution/observation matching system has been proposed to account for this impairment. The EEG mu rhythm is believed to reflect an underlying execution/observation matching system. This study investigated evidence of differential mu rhythm attenuation during the observation, execution, and imitation of movements and examined its relation to behaviorally assessed imitation abilities. Fourteen high-functioning adults with autism spectrum disorder (ASD) and 15 IQ- and age-matched typical adults participated. On the behavioral imitation task, adults with ASD demonstrated significantly poorer performance compared to typical adults in all domains of imitation ability. On the EEG task, both groups demonstrated significant attenuation of the mu rhythm when executing an action. However, when observing movement, the individuals with ASD showed significantly reduced attenuation of the mu wave. Behaviorally assessed imitation skills were correlated with degree of mu wave attenuation during observation of movement. These findings suggest that there is execution/observation matching system dysfunction in individuals with autism and that this matching system is related to degree of impairment in imitation abilities.

    MuSI, a gene that corresponds to a domain that contains the rubber elongation factor (REF), is highly homologous to many stress-related proteins in plants. Since MuSI is up-regulated in the roots of plants treated with cadmium or copper, the involvement of MuSI in cadmium tolerance was investigated in this study. Escherichia coli cells overexpressing MuSI were more resistant to Cd than wild-type cells transfected with vector alone. MuSI transgenic plants were also more resistant to Cd. MuSI t...

  3. Potential of MuS1 Transgenic Tobacco for Phytoremediation of the Urban Soils Contaminated with Cadmium

    Urban soils are prone to contamination by trace elements such as Cd, Cu, Pb and Zn. Phytoremediation is one of the attractive remediation methods for soils contaminated with trace elements due to its non-destructive and environmentally-friendly characteristic. Scientists have tried to find hyper-accumulator plants in nature or to develop transgenic plant through genetic engineering. This study was carried out to identify a potential of MuS1 transgenic tobacco for phytoremediation of the urban soils contaminated with Cd. MuS1 is known as a multiple stress related gene with several lines. The previous study using RT-PCR showed that the expression of MuS1 gene in tobacco plant induced tolerance to Cd stress. For this study, MuS1 transgenic tobacco and wild-type tobacco (control) were cultivated in a hydroponic system treated with Cd (0, 50, 100 and 200μM Cd) for 3 weeks. At harvest, both tobacco and nutrient solution were collected and were analyzed for Cd. Effect of Cd treatment on morphological change of the tobacco leaves was also observed by variable-pressure scanning electron microscopy (VP-SEM). The tolerance of MuS1 transgenic tobacco to Cd stress was better than that of wild-type tobacco at all Cd levels. Especially, wild-type tobacco showed chlorosis and withering with 200μM Cd treatment, whereas MuS1 transgenic tobacco gradually recovered from Cd damage. Wild-type tobacco accumulated more Cd (4.65mg per plant) than MuS1 transgenic tobacco (2.37mg per plant) with 200μM Cd treatment. Cd translocation rate from root to leaves was 81.8 % for wild-type tobacco compared to 37.1 % for MuS1 transgenic tobacco. Result of VP-SEM showed that the number of trichome in the leaves for wild-type tobacco increased in comparison with that for untreated samples after 3 weeks, while that for MuS1 transgenic tobacco was not changed by Cd treatment. Results showed that the mechanism of the recovery of the MuS1 tobacco plant was not by high level of Cd uptake and accumulation

    In this work we review muon spin relaxation experiments on the layered La{sub 2-x}Sr{sub x}NiO{sub 4} nickelate as well as La{sub 2-x}Ba{sub x}CuO{sub 4} and La{sub 2-x}Sr{sub x}CuO{sub 4} cuprate systems to examine spin stripe order. In particular, the interplay of stripe order with superconductivity in Nd and Eu doped La{sub 2-x}Sr{sub x}CuO{sub 4} cuprates is discussed. Detailed studies of the electronic phase diagrams as well as the magnetic and superconducting order parameters for different rare-earth and Sr doping levels in La{sub 2-x-y}RE{sub y}Sr{sub x}CuO{sub 4} revealed the strong correlation of static spin stripe order with the structural distortion in the low temperature tetragonal (LTT) phase and the competition with the superconducting ground state. High magnetic field studies demonstrate the nearly degenerate ground state energy of the different electronic phases. Slow transverse fluctuations of the charge stripes are found in nickelates and cuprates at low temperatures.

    The ATLAS (A Toroidal LHC ApparatuS) detector is one of the four detectors which will be installed in the new accelerator, at LHC, CERN. One of the experiments' research aims is the discovery of the Higgs particle and thus, the confirmation or not of the Standard Model. The Muon Spectrometer of the detector has special importance, because the decay channels of the Higgs particle which have muons at the final state are clear signatures of the existence of the Higgs particle. This project focuses on the Higgs decay through the channel: H->ZZ->4mu. The alignment of the muon detectors has to be very accurate, so that its contribution on the measurement of the muons' momentum, to be low compared to the intrinsic resolution of the detectors themselves. Although the alignment of the muons detectors at the barrel and the end-caps regions is well controlled, the relative alignment of the end-caps with respect to barrel is not controlled with the same accuracy. In this project, we study the influence of such misalignme...

  8. Study of the interface in n{sup +}{mu}c-Si/p-type c-Si heterojunctions: role of the fluorine chemistry in the interface passivation

    2003-03-03

    Investigation of n-p heterojunction solar cells obtained by depositing a n-type thin silicon films either amorphous or microcrystalline on p-type c-Si is carried out. The study is focused on the improvement of the c-Si surface and emitter layer/c-Si substrate interface. The peculiarity is the use of SiF{sub 4}-based plasmas for the in situ dry cleaning and passivation of the c-Si surface and for the PECVD deposition of the emitter layer that can be either amorphous (a-Si:H,F) or microcrystalline ({mu}c-Si). The use of SiF{sub 4} instead of the conventional SiH{sub 4} results in a lower hydrogen content in the film and in a reduction of the interaction of the c-Si surface with hydrogen atoms. Furthermore, the dependence of the heterojunction solar cell photovoltaic parameters on the insertion of an intrinsic buffer layer between the n-type thin silicon layer and the p-type c-Si substrate is discussed.

  9. LHCb: Search for the rare decays $B^0_{(s)} \\to \\mu^+\\mu^-$ with the LHCb Experiment

    2011-01-01

    A review of the search for the very rare decays $B^{0}_{s} \\rightarrow \\mu^+ \\mu^-$ and $B^{0} \\rightarrow \\mu^+ \\mu^-$ with the LHCb experiment is presented. These decays are suppressed within the Standard Model as they can only occur via helicity suppressed loop diagrams. However, their amplitudes can be significantly different in many New Physics scenarios, especially in those with an extended Higgs sector. Therefore, these decays are a sensitive probe of physics beyond the Standard Model. The study is performed using $\\sim 37$ $pb^{-1}$ of pp collisions at $\\sqrt{s}$ = 7 TeV collected by the experiment at the Large Hadron Collider at CERN. For these dimuon decays the LHCb has reached sensitivities similar to the best existing limits. The resulting upper limits are $\\mathcal{B}(B^{0}_{s} \\rightarrow \\mu^+ \\mu^-)<$ 56 $\\times$ $10^{-9}$ and $\\mathcal{B}(B^{0} \\rightarrow \\mu^+ \\mu^-)<$ 15 $\\times$ $10^{-9}$ at $95\\%$ confidence level. With the number of pp colisions expected in 2011 the LHCb will ...

    A search for the rare decays $B^0_s \\to\\mu^+\\mu^-$ and $B^0 \\to\\mu^+\\mu^-$ is performed at the LHCb experiment. The data analysed correspond to an integrated luminosity of 1 fb$^{-1}$ of $pp$ collisions at a centre-of-mass energy of 7 TeV and 2 fb$^{-1}$ at 8 TeV. An excess of $B^0_s \\to\\mu^+\\mu^-$ signal candidates with respect to the background expectation is seen with a significance of 4.0 standard deviations. A time-integrated branching fraction of ${\\cal B}(B^0_s \\to\\mu^+\\mu^-) = (2.9^{+1.1}_{-1.0})\\times 10^{-9}$ is obtained and an upper limit of ${\\cal B}(B^0 \\to\\mu^+\\mu^-) < 7.4\\times 10^{-10}$ at 95% confidence level is set. These results are consistent with the Standard Model expectations.

    The well-known Giudice-Masiero mechanism explains the presence of a {mu} term of the order of the gravitino mass, but does not explain why the holomorphic mass term is absent in the superpotential. We discuss anomaly-free discrete symmetries which are both compatible with SU(5) unification of matter and the Giudice-Masiero mechanism, i.e. forbid the {mu} term in the superpotential while allowing the necessary Kaehler potential term. We find that these are Z{sup R}{sub M} symmetries with the following properties: (i) M is a multiple of four; (ii) the Higgs bilinear H{sub u} H{sub d} transforms trivially; (iii) the superspace coordinate {theta} has charge M/4 and, accordingly, the superpotential has charge M/2; (iv) dimension five proton decay operators are automatically absent. All Z{sup R}{sub M} symmetries are anomaly-free due to a non-trivial transformation of a Green-Schwarz axion, and, as a consequence, a holomorphic {mu} term appears at the non-perturbative level. There is a unique symmetry that is consistent with the Weinberg operator while there is a class of Z{sup R}{sub M} symmetries which explain suppressed Dirac neutrino masses.

    We consider the extension of the Minimal Supersymmetric Standard Model by Dirac masses for the gauginos. We study the possibility that the same singlet S that pairs up with the bino, to form a Dirac fermion, is used to generate {mu} and B{mu} terms through its vacuum expectation value. For this purpose, we assume that, in the Higgs potential, the necessary R-symmetry breaking originates entirely from a superpotential term ({kappa})/(3)S{sup 3} and discuss the implications for the spectrum of the model.

    The isospin asymmetries of $B \\to K^{(*)}\\mu^+\\mu^-$ decays and the partial branching fractions of $B^0 \\to K^0\\mu^+\\mu^-$ and $B^+ \\to K^{*+}\\mu^+\\mu^-$ are measured as a function of the di-muon mass squared $q^2$ using an integrated luminosity of 1.0 fb$^{-1}$ collected with the LHCb detector. The $B \\to K\\mu^+\\mu^-$ isospin asymmetry integrated over $q^2$ is negative, deviating from zero with over 4 $\\sigma$ significance. The $B \\to K^{*}\\mu^+\\mu^-$ decay measurements are consistent with the Standard Model prediction of negligible isospin asymmetry. The observation of the decay $B^0 \\to K^0_{\\rm\\scriptscriptstyle S}\\mu^+\\mu^-$ is reported with 5.7 $\\sigma$ significance. Assuming that the branching fraction of $B^0 \\to K^0\\mu^+\\mu^-$ is twice that of $B^0 \\to K^0_{\\rm\\scriptscriptstyle S}\\mu^+\\mu^-$, the branching fractions of $B^0 \\to K^0\\mu^+\\mu^-$ and $B \\to K^{*+}\\mu^+\\mu^-$ are found to be ($0.31^{+0.07}_{-0.06}) \\times 10^{-6}$ and ($1.16\\pm0.19) \\times 10^{-6}$, respectively.

    the perturbations which produce the $\\mu$-distortion will be much smaller scale than the relevant density perturbations, the observation of this correlation is sensitive to the squeezed limit of $\\langle B^2\\zeta\\rangle$, which is naturally parameterized by $b_{\\text{NL}}$ (a parameter defined analogously to $f_{\\text......{NL}}$). We find that a PIXIE-like CMB experiments has a signal to noise $S/N\\approx 1.0 \\times b_{\\text{NL}} (\\tilde B_\\mu/10\\text{ nG})^2$, where $\\tilde B_\\mu$ is the magnetic field's strength on $\\mu$-distortion scales normalized to today's redshift; thus, a 10 nG field would be detectable with $b_{\\text...

  17. Action experience, more than observation, influences mu rhythm desynchronization.

    Directory of Open Access Journals (Sweden)

    Erin N Cannon

    Full Text Available Since the discovery of mirror neurons in premotor and parietal areas of the macaque monkey, the idea that action and perception may share the same neural code has been of central interest in social, developmental, and cognitive neurosciences. A fundamental question concerns how a putative human mirror neuron system may be tuned to the motor experiences of the individual. The current study tested the hypothesis that prior motor experience modulated the sensorimotor mu and beta rhythms. Specifically, we hypothesized that these sensorimotor rhythms would be more desynchronized after active motor experience compared to passive observation experience. To test our hypothesis, we collected EEG from adult participants during the observation of a relatively novel action: an experimenter used a claw-like tool to pick up a toy. Prior to EEG collection, we trained one group of adults to perform this action with the tool (performers. A second group comprised trained video coders, who only had experience observing the action (observers. Both the performers and the observers had no prior motor and visual experience with the action. A third group of novices was also tested. Performers exhibited the greatest mu rhythm desynchronization in the 8-13 Hz band, particularly in the right hemisphere compared to observers and novices. This study is the first to contrast active tool-use experience and observation experience in the mu rhythm and to show modulation with relatively shorter amounts of experience than prior mirror neuron expertise studies. These findings are discussed with respect to its broader implication as a neural signature for a mechanism of early social learning.

  18. A Study of Hypergiant Mass Loss in the Near-To-Mid Infrared: VY CMa, IRC +10420, mu Cep and rho Cas

    Stars of initial mass greater than 9 M_sun become red supergiants (RSGs), a short-lived stage during which they experience mass-loss that strongly influences their post-RSG evolution and end state. The highest luminosity RSGs, referred to here as hypergiants, experience episodic mass-loss whose mechanism remains poorly understood and motivates observations to help constrain it. This thesis studies mass loss from hypergiant stars with near-to-mid infrared imaging over a range of angular scales. The recent mass-loss history of the extreme red supergiant VY Canis Majoris and the warm hypergiant star IRC +10420 are studied at the sub-arcsecond scale with adaptive optics imaging and imaging polarimetry from 1 - 5 micron using LMIRCam on the Large Binocular Telescope (LBT) and MMT-Pol at the MMT Observatory. The nebular features of VY CMa are found to be highly polarized at 1.3 and 3.1 micron, with optically thick scattering required to reproduce the observed surface brightness. The flux of VY CMa's peculiar ``Southwest Clump'' is demonstrated to be due almost entirely to optically thick scattering, with little thermal emission, and with a lower limit mass of 5E-03 M_sun in this single feature. The imaging polarimetry of IRC +10420 at 2.2 micron resolves nebular emission with intrinsic polarization of 30%, with a high surface brightness indicating optically thick scattering largely in the plane of the sky. Using the polarimetry to constrain the scattered light emission, it is shown that the nebula's the emission is mostly thermal with a color temperature well above that for typical astrophysical dust. To probe further into hypergiants' history of mass-loss, mid-IR imaging with MMT/ MIRAC and SOFIA/FORCAST is used to study VY CMa, IRC +10420 and two additional hypergiants: the RSG mu Cep and the warm hypergiant rho Cas. Using DUSTY 1-D radiative transfer models, mu Cep's mass-loss rate is found to have declined by about a factor of 5 over a 13,000 history, ranging from 5E

  19. Mu2e Technical Design Report

    Energy Technology Data Exchange (ETDEWEB)

    Bartoszek, L.; et al.

    2014-10-01

    Fermi National Accelerator Laboratory and the Mu2e Collaboration, composed of about 155 scientists and engineers from 28 universities and laboratories around the world, have collaborated to create this technical design for a new facility to study charged lepton flavor violation using the existing Department of Energy investment in the Fermilab accelerator complex. Mu2e proposes to measure the ratio of the rate of the neutrinoless, coherent conversion of muons into electrons in the field of a nucleus, relative to the rate of ordinary muon capture on the nucleus. The conversion process is an example of charged lepton flavor violation (CLFV), a process that has never been observed experimentally. The significant motivation behind the search for muon-to-electron conversion is discussed in Chapter 3.

  20. From a {nu} factory to {mu} super + mu super {minus} Colliders

    An important feature of a {mu}-storage ring {nu}-source is that it can be extended to the possibility of a future high-energy muon collider. The neutrino source provides a useful physics device that initiates key technologies required for future {mu}{sup +}-{mu}{sup {minus}} Colliders, but with much less demanding parameter requirements. These technologies include high-intensity {mu}-production, {mu}-capture, {mu}-cooling, {mu}-acceleration and multiturn {mu} storage rings. {mu}{sup +}-{mu}{sup {minus}} colliders require a similar number of muons, but they require that the muons be cooled to a much smaller phase space and formed into a small number of bunches, and both positive and negative bunches must be simultaneously captured. These differences are discussed, and the extension of the {nu}-source to {mu}{sup +}-{mu}{sup {minus}} collider specifications is described.

    Beam halo scraping schemes have been explored in the 50 x 50 GeV and 2 x 2 TeV {mu}{sup +}{mu}{sup -} colliders using both absorbers and electrostatic deflectors. Utility sections have been specially designed into the rings for scraping. Results of realistic STRUCT- MARS Monte-Carlo simulations show that for the low-energy machine a scheme with a 5 m long steel absorber suppresses losses in the interaction region by three orders of magnitude. The same scraping efficiency at 2 TeV is achieved only by complete extraction of beam halo from the machine. The effect of beam-induced power dissipation in the collider superconducting magnets and detector backgrounds is shown both for the first few turns after injection and for the rest of the cycle.

    We used magnetoencephalography to investigate the effect of directed attention on sensorimotor mu (8-12 Hz) response (mu reactivity) to non-painful electrical stimulation of the median nerve in healthy adults. Mu desynchronization in the 10-12 Hz bandwidth is typically observed during higher-order cognitive functions including selective attentional processing of sensorimotor information (Pfurtscheller, Neuper, & Krauz, 2000). We found attention-related sex differences in mu reactivity, with females showing (i) prolonged mu desynchrony when attending to somatosensory stimuli, (ii) attentional modulation of the mu response based on whether attention was directed towards or away from somatosensory stimuli, which was absent in males, and (iii) a trend for greater neuronal excitability of the primary somatosensory region suggesting greater physiological responsiveness to sensory stimulation overall. Our findings suggest sex differences in attentional control strategies when processing somatosensory stimuli, whose salience may be greater for females. These sex differences in attention to somatosensory stimuli may help elucidate the well-documented sex biases in pain processing wherein females typically report greater sensitivity to experimental and clinical pain.

    We introduce a version of the probabilistic µ-calculus (PMC) built on top of a probabilistic modal logic that allows encoding n-ary inequational conditions on transition probabilities. PMC extends previously studied calculi and we prove that, despite its expressiveness, it enjoys a series of good...... metaproperties. Firstly, we prove the decidability of satisfiability checking by establishing the small model property. An algorithm for deciding the satisfiability problem is developed. As a second major result, we provide a complete axiomatization for the alternation-free fragment of PMC. The completeness proof...

  4. Exploiting angular correlations in the rare decay $B\\rightarrow K^{*}\\mu^{+}\\mu^{-}$ at LHCb

    Reece, William Robert

    2010-01-01

    In this thesis, methods for studying the flavour-changing neutral current decay $B\\rightarrow K^{*}\\mu^{+}\\mu^{-}$ at LHCb are investigated. The decay proceeds via a $b\\rightarrow s$ loop, and will be sensitive to the effects of new particles, predicted in many models of beyond-the-Standard-Model physics. The formalism used to describe the decay will be introduced, and a number of observables available in its angular distribution presented. In the first few years of LHCb data taking, the number of signal events available will be relatively small and measurements must be optimized for experimental sensitivity. The vanishing point of the angular observable $S_{5}$ will be of particular interest; it has reduced theoretical uncertainties from hadronic form factors and can be extracted with high precision at LHCb. It provides a complementary measurement to that of $A_{FB}$ and $F_{L}$, already considered by BaBar, Belle, and CDF. Once $\\mathcal{O}(10^{4})$ $B\\rightarrow K^{*}\\mu^{+}\\mu^{-}$ signal events have been...

    The isospin asymmetries of $B \\to K\\mu^+\\mu^-$ and $B \\to K^{*}\\mu^+\\mu^-$ decays and the partial branching fractions of the $B^0 \\to K^0\\mu^+\\mu^-$, $B^+ \\to K^+\\mu^+\\mu^-$ and $B^+ \\to K^{*+}\\mu^+\\mu^-$ decays are measured as functions of the dimuon mass squared, $q^2$. The data used correspond to an integrated luminosity of 3 fb$^{-1}$ from proton-proton collisions collected with the LHCb detector at centre-of-mass energies of 7 TeV and 8 TeV in 2011 and 2012, respectively. The isospin asymmetries are both consistent with the Standard Model expectations. The three measured branching fractions, while individually consistent, all favour lower values than their respective Standard Model predictions.

    A measurement of the $C\\!P$ asymmetry in $B^0 \\rightarrow K^{*0} \\mu^+ \\mu^-$ decays is presented, based on 1.0$\\mbox{\\,fb}^{-1}$ of $pp$ collision data recorded by the LHCb experiment during 2011. The measurement is performed in six bins of invariant mass squared of the $\\mu^+\\mu^-$ pair, excluding the $\\mathrm{J}\\mskip -3mu/\\mskip -2mu\\psi\\mskip 2mu$ and $\\psi(2S)$ resonance regions. Production and detection asymmetries are removed using the $B^0 \\rightarrow \\mathrm{J}\\mskip -3mu/\\mskip -2mu\\psi\\mskip 2mu K^{*0}$ decay as a control mode. The integrated $C\\!P$ asymmetry is found to be $-0.072 \\pm 0.040 \\,(\\mbox{stat.}) \\pm 0.005 \\,(\\mbox{syst.})$, consistent with the Standard Model.

  7. Analgesia produced by exposure to 2450-MHz radiofrequency radiation (RFR) is mediated by brain mu- and kappa-opioid receptors

    This study was conducted to identify the opioid receptor subtype(s) responsible for RFR-induced analgesia. Male Swiss Webster mice, 20-25 g, were exposed to 20 mW/cm{sup 2} RFR in a 2,450-MHz waveguide system for 10 min, then tested 15 min later in the abdominal constriction paradigm which detects {mu}- and {kappa}-opioid activity. Immediately following RFR exposure, different groups of mice were pretreated intracerebroventricularly with different opioid receptor blockers with selectivity for {mu}- or {kappa}-opioid receptors. Results show that RFR-induced analgesia was attenuated by higher but not lower doses of the non-selective antagonist naloxone, but the selective {mu}-opioid antagonist {beta}-funaltrexamine and by the selective {kappa}-opioid antagonist norbinaltorphimine. RFR-induced analgesia was also reduced by subcutaneous pretreatment with 5.0 mg/kg of the {mu}-/{kappa}-opioid antagonist({minus})-5,9-diethyl-{alpha}-5,9-dialkyl-2{prime}-hydroxy-6,7-benzomorphan(MR-2266). These findings suggest that RFR-induced analgesia may be mediated by both {mu}- and {kappa}-opioid mechanisms.

    A study of the decay $D^{0}\\rightarrow K^{-}\\pi^{+}\\mu^{+}\\mu^{-}$ is performed using data collected by the LHCb detector in proton-proton collisions at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 2.0 fb$^{-1}$. Decay candidates with muon pairs that have an invariant mass in the range 675--875 MeV$/c^2$ are considered. This region is dominated by the $\\rho^{0}$ and $\\omega$ resonances. The branching fraction in this range is measured to be ${\\cal B}$($D^{0}\\rightarrow K^{-}\\pi^{+}\\mu^{+}\\mu^{-}$ ) = $( 4.17 \\pm 0.12(stat) \\pm 0.40(syst) )\\times10^{-6}$. This is the first observation of the decay $D^{0}\\rightarrow K^{-}\\pi^{+}\\mu^{+}\\mu^{-}$. Its branching fraction is consistent with the value expected in the Standard Model.

This new approach, which draws on experimental archaeology, has made it possible to render textile craft visible, even if the textiles themselves...... are not preserved (Mårtensson et al. 2009). It is this approach that has been adopted in the following analysis of the loom weights from Quartier Mu. The chapter divided into four parts. The first part gives an outline of general textile techniques and presents the methodology. The second part consists...

  11. Search for $C\\!P$ violation in $\\Lambda_b\\to pK^-\\mu^+\\mu^-$ decays

    AUTHOR|(CDS)2091898; Neri, Nicola

    In this thesis the first search for $C\\!P$-violation on rare heavy beauty baryon $\\Lambda_b\\to pK^-\\mu^+\\mu^-$ decays is described. This analysis is carried out on the whole dataset recorded by the LHCb experiment during 2011 and 2012. The $C\\!P$ symmetry violation study is one of the most promising method for searching physics beyond the standard model, as the measured amount of $C\\!P$-violation in high-energy physics experiments, even though compatible with standard model expectations, is not sufficient for explaining the observed matter-antimatter asymmetry of our universe. The $\\Lambda_b\\to pK^-\\mu^+\\mu^-$ decays occur via electroweak loop diagrams which allow possible new physics fields to give this process a sensible contribution. For the $\\Lambda_b\\to pK^-\\mu^+\\mu^-$ decay a limited quantity of $C\\!P$-violation is expected in the standard model, making this transition suited to look for beyond standard model physics. In this thesis, $C\\!P$-violation is searched exploiting direct $C\\!P$ asymmetries and ...

    A search for $C\\!P$ violation in the rare decay $\\Lambda^0_b \\to p K^- \\mu^+ \\mu^-$ is presented. This decay is mediated by flavour-changing neutral-current transitions in the Standard Model and is potentially sensitive to new sources of $C\\!P$ violation. The study is based on a data sample of proton-proton collisions recorded with the LHCb experiment, corresponding to an integrated luminosity of $3\\mathrm{fb}^{-1}$. Two observables that are sensitive to different manifestations of $C\\!P$ violation are measured, $\\Delta\\mathcal{A}_{C\\!P} \\equiv \\mathcal{A}_{C\\!P}(\\Lambda^0_b \\to p K^- \\mu^+ \\mu^-)-\\mathcal{A}_{C\\!P}(\\Lambda^0_b\\to pK^- J/\\psi)$ and $a_{C\\!P}^{\\widehat{T}_{\\mathrm{odd}}}$, where the latter is based on asymmetries in the angle between the $\\mu^+\\mu^-$ and $p K^-$ decay planes. No evidence for $C\\!P$ violation is found.

  13. Discovery and Use of Online Learning Resources: Case Study Findings

    Directory of Open Access Journals (Sweden)

    Full Text Available Much recent research and funding have focused on building Internet-based repositories that contain collections of high-quality learning resources, often called ‘learning objects.’ Yet little is known about how non-specialist users, in particular teachers, find, access, and use digital learning resources. To address this gap, this article describes a case study of mathematics and science teachers’ practices and desires surrounding the discovery, selection, and use of digital library resources for instructional purposes. Findings suggest that the teacher participants used a broad range of search strategies in order to find resources that they deemed were age-appropriate, current, and accurate. They intended to include these resources with little modifications into planned instructional activities. The article concludes with a discussion of the implications of the findings for improving the design of educational digital library systems, including tools supporting resource reuse.

    Migraine has long been known as a common complex disease caused by genetic and environmental factors. The pathophysiology and the specific genetic susceptibility are poorly understood. Common variants only explain a small part of the heritability of migraine. It is thought that rare genetic variants with bigger effect size may be involved in the disease. Since migraine has a tendency to cluster in families, a family approach might be the way to find these variants. This is also indicated by identification of migraine-associated loci in classical linkage-analyses in migraine families. A single migraine study using a candidate-gene approach was performed in 2010 identifying a rare mutation in the TRESK potassium channel segregating in a large family with migraine with aura, but this finding has later become questioned. The technologies of next-generation sequencing (NGS) now provides an affordable tool to investigate the genetic variation in the entire exome or genome. The family-based study design using NGS is described in this paper. We also review family studies using NGS that have been successful in finding rare variants in other common complex diseases in order to argue the promising application of a family approach to migraine. PubMed was searched to find studies that looked for rare genetic variants in common complex diseases through a family-based design using NGS, excluding studies looking for de-novo mutations, or using a candidate-gene approach and studies on cancer. All issues from Nature Genetics and PLOS genetics 2014, 2015 and 2016 (UTAI June) were screened for relevant papers. Reference lists from included and other relevant papers were also searched. For the description of the family-based study design using NGS an in-house protocol was used. Thirty-two successful studies, which covered 16 different common complex diseases, were included in this paper. We also found a single migraine study. Twenty-three studies found one or a few family specific

    The direct $C\\!P$ asymmetries of the decays $B^0 \\rightarrow K^{*0} \\mu^+ \\mu^-$ and $B^+ \\rightarrow K^{+} \\mu^+ \\mu^-$ are measured using $pp$ collision data corresponding to an integrated luminosity of 3.0$\\mbox{fb}^{-1}$ collected with the LHCb detector. The respective control modes $B^0 \\rightarrow J/\\psi K^{*0}$ and $B^+ \\rightarrow J/\\psi K^{+}$ are used to account for detection and production asymmetries. The measurements are made in several intervals of $\\mu^+ \\mu^-$ invariant mass squared, with the $\\phi(1020)$ and charmonium resonance regions excluded. Under the hypothesis of zero $C\\!P$ asymmetry in the control modes, the average values of the asymmetries are \\begin{align} {\\cal A}_{C\\!P}(B^0 \\rightarrow K^{*0} \\mu^+ \\mu^-) &= -0.035 \\pm 0.024 \\pm 0.003, \\cr {\\cal A}_{C\\!P}(B^+ \\rightarrow K^{+} \\mu^+ \\mu^-) &= \\phantom{-}0.012 \\pm 0.017 \\pm 0.001, \\end{align} where the first uncertainties are statistical and the second are due to systematic effects.

    Objective: To determine the agreement/variability between colposcopic findings, Pap smear cytology and histopathological diagnosis in gynaecology patients. Methods: The cross-sectional cohort study was conducted from October 2010 to September 2011 at the Fauji Foundation Hospital, Rawalpindi, and comprised women who presented to the out-patient department with various gynaecological complaints. Colposcopy was performed in all women with unhealthy cervix during gynaecological examination, abnormal Pap smear report, recurrent vaginal discharge and postcoital bleeding. Pap smear was performed before colposcopy if not done earlier. Colposcopic findings were recorded on a specially-designed proforma. Biopsies from abnormal areas were taken and sent for histopathology. Colposcopic findings were compared with histopathology and Pap smear reports The agreement between the methods was evaluated by using Kappa coefficient and chi square test at a significance level of 5 percent. Results: The mean age of the 143 women was 44 8.5 years (range: 25-72 years). Colposcopic findings were normal in 66(46 percent) women, while 77(54 percent) had abnormal findings and among the latter, 62(80.5 percent) had abnormal histopathology, indicating strong agreement (K=0.65; p<0.001). Pap smear report was abnormal in 48(33.5 percent) cases and among them histopathology was abnormal in 28(58 percent). In the remaining 95(66.4 percent) patients with normal Pap smear, histopathology was abnormal in 44((46 percent), indicating weak agreement between Pap smear and histopathological diagnosis (K=0.10; p=0.08). Conclusion: There was a strong agreement between colposcopic findings and histopathological diagnosis. However, agreement between cytological findings and colposcopic findings and cytology and histopathological diagnosis remained weak. (author)

    Observation of 16 mu /sup +/ mu /sup -/ pairs of invariant mass greater than 2.7 GeV/c/sup 2/ in the reaction pp to mu /sup +/ mu /sup -/+anything at square root s=52 GeV at the CERN Intersecting Storage Rings (ISR) is reported. These events can be interpreted as originating from J(3.1) decay into mu /sup +/ mu /sup -/. Their p/sub T/ distribution suggests a hadronic production. The cross section for J production is given and compared to the cross section for single lepton production. It is concluded that J(3.1) production cannot fully account for single lepton production.

    This study is aimed at an assessment of the methodologies, instruments and new applications for underwater archaeology. Research focused on study of the various kinds of degradation affecting underwater finds and stone materials aged in underwater environment, efficiency evaluation of various surface cleaning methods and study and mixing of protective products with consolidating resins and antimicrobial biocides to be applied to restored underwater finds. Transmitted light optical microscopy and scanning electron microscopy (SEM) were used to study surface biofilms and the interactions with samples of different stone materials such as brick, marble and granite immersed in the submarine archaeological area of Crotone (South of Italy). Surface cleaning tests were performed with application of ion exchange resins, EDTA, hydrogen peroxide and ultrasound techniques. Capillary water absorption, simulated solar ageing and colourimetric measurements were carried out to evaluate hydrophobic and consolidant properties; to assess biocidal efficacy, heterotrophic micro-organisms ( Aspergillus niger) were inoculated on agar plates and growth inhibition was measured.

    We report the first evidence for the decay Sigma(+)-->pmu(+)mu(-) from data taken by the HyperCP (E871) experiment at Fermilab. Based on three observed events, the branching ratio is B(Sigma(+)-->pmu(+)mu(-))=[8.6(+6.6)(-5.4)(stat)+/-5.5(syst)]x10(-8). The narrow range of dimuon masses may indicate that the decay proceeds via a neutral intermediate state, Sigma(+)-->pP(0),P0-->mu(+)mu(-) with a P0 mass of 214.3+/-0.5 MeV/c(2) and branching ratio B(Sigma(+)-->pP(0),P0-->mu(+)mu(-))=[3.1(+2.4)(-1.9)(stat)+/-1.5(syst)]x10(-8).

  3. Prospects for measuring the branching ratio of the rare B{sup 0}{sub s}{yields}{mu}{sup +}{mu}{sup -} decay with the ATLAS experiment

    2011-09-15

    The Large Hadron Collider (LHC) located at the CERN laboratory in Geneva provides p-p collisions at a centre-of-mass energy of {radical}(s)=7 TeV. The study of the rare B{sup 0}{sub s}{yields}{mu}{sup +}{mu}{sup -} decay is among the research topics of ATLAS, one of the main experiments at the LHC. This decay is highly suppressed in the Standard Model of particle physics and may give an indirect evidence for New Physics models. This PhD thesis investigates prospects for measuring the branching ratio of the B{sup 0}{sub s}{yields}{mu}{sup +}{mu}{sup -} decay with the ATLAS experiment. The analysis is based on Monte Carlo data, with p-p collisions generated at a centre-of-mass energy of {radical}(s)=10 TeV. The strategy employed is to calculate the B{sup 0}{sub s}{yields}{mu}{sup +}{mu}{sup -} branching ratio relative to the branching ratio of the B{sup +}{yields} J/{psi}({mu}{sup +}{mu}{sup -})K{sup +} decay. The dominant background channel is the b anti b{yields}{mu}{sup +}{mu}{sup -}X combinatorial background. True B{sup 0}{sub s}{yields}{mu}{sup +}{mu}{sup -} decay candidates are separated from the much larger amount of combinatorial background events using several discriminating quantities. Upper limits on the B{sup 0}{sub s} {yields} {mu}{sup +}{mu}{sup -} branching ratio are computed using a Bayesian and a frequentist method. The expected precision of the branching ratio measurement is estimated for different values of the integrated luminosity. An expected upper limit on the branching ratio is computed to BR(B{sup 0}{sub s}{yields}{mu}{sup +}{mu}{sup -})<3.8 x 10{sup -8} at a 95% confidence level for 1 fb{sup -1}. The precision of the ATLAS measurement of the branching ratio will reach a level compatible with the best current measurements with about 2-5 fb{sup -1} of data.

    The purpose of this study is to describe the MRI findings and treatment decisions and outcome for Morel-Lavallée lesions (MLLs) of the knee and to investigate whether evidence exists to support an increased frequency of such lesions on the medial or lateral side by performing a cadaveric experiment. In a 4-year period, 24 MRI studies of 24 consecutive patients (16 male patients and eight female patients) with knee MLLs were retrospectively reviewed. Patient demographic characteristics, treatment decisions and outcome, and associated injuries were recorded. The location of the MLL was categorized as medial, lateral, or global. Lesions were categorized according to an established MRI classification. During the cadaveric experiment, the compartmental pressures of the medial or lateral aspect of the knee were monitored in 20 cadaveric knees. The chi-square test, t test, and Pearson correlation were used for statistical analysis. MLLs were located medially in 16 patients, laterally in two patients, and globally in six patients. The medial location was significantly more common than a lateral or global location (p < 0.05). MLLs were classified as type I in 14 patients, type II in eight patients, and type III in two patients. MRI type was correlated with the chronicity of injury (r 2 = 0.614; p = 0.0014). Fractures were the most common associated injuries, occurring in seven of 24 patients. In 17 patients, all of whom had conservatively treated type I or type II lesions, complete resolution of the MLL occurred. The maximum compartmental pressures were significantly higher on the lateral side than on the medial side (p < 0.0001). Knee MLLs have a predilection for the medial side, which may be attributed to the lower resistance in this location, and they have variable patterns on MRI, which correlate with chronicity. Conservative treatment of type I and II lesions seems effective.

    2004-09-15

    The Australian Government established the National Dioxins Program (NDP) in 2001 to improve knowledge about levels of dioxins in Australia. The program aims to determine levels, assess the risks to Australians and the environment, and to consider appropriate management actions. Starting in mid 2001and completed in 2004, the studies constituted the largest survey of dioxin levels ever undertaken in Australia. The findings will contribute to debate on how to deal with dioxins in Australia, as well as helping to meet obligations under the Stockholm Convention on Persistent Organic Pollutants, which Australia ratified on 20 May 2004. These studies will also contribute to a better understanding about dioxins in the southern hemisphere. This paper provides a summary of the key findings of these studies and the risk assessments.

    This study evaluated the role of breast magnetic resonance (MR) imaging in the selective study breast implant integrity. We retrospectively analysed the signs of breast implant rupture observed at breast MR examinations of 157 implants and determined the sensitivity and specificity of the technique in diagnosing implant rupture by comparing MR data with findings at surgical explantation. The linguine and the salad-oil signs were statistically the most significant signs for diagnosing intracapsular rupture; the presence of siliconomas/seromas outside the capsule and/or in the axillary lymph nodes calls for immediate explantation. In agreement with previous reports, we found a close correlation between imaging signs and findings at explantation. Breast MR imaging can be considered the gold standard in the study of breast implants.

    A measurement of the $C\\!P$ asymmetry in $B^+ \\rightarrow K^+ \\mu^+ \\mu^-$ decays is presented using $pp$ collision data, corresponding to an integrated luminosity of 1.0 fb $^{-1}$, recorded by the LHCb experiment during 2011 at a centre-of-mass energy of 7 TeV. The measurement is performed in seven bins of $\\mu^+ \\mu^-$ invariant mass squared in the range 0.05 < $q^{2}$ < 22.00 GeV$^{2}/c^4$, excluding the ${J\\mskip -3mu/\\mskip -2mu \\psi\\mskip 2mu}$ and $\\psi{(2S)}$ resonance regions. Production and detection asymmetries are corrected for using the $B^+ \\rightarrow J\\mskip -3mu/\\mskip -2mu \\psi\\mskip 2mu K^+$ decay as a control mode. Averaged over all the bins, the $C\\!P$ asymmetry is found to be ${{\\cal A}_{C\\!P} = 0.000\\pm 0.033\\mbox{ (stat.)} \\pm0.005 \\mbox{ (syst.)} \\pm 0.007\\mbox{ }(J\\mskip -3mu/\\mskip -2mu \\psi\\mskip 2mu K^+)}$, where the third uncertainty is due to the $C\\!P$ asymmetry of the control mode. This is consistent with the Standard Model prediction.

  9. The Mu3e Tile Detector

    Energy Technology Data Exchange (ETDEWEB)

    Eckert, Hans Patrick

    2015-05-06

    The Mu3e experiment is designed to search for the lepton flavour violating decay μ→e{sup +}e{sup +}e{sup -} with a sensitivity of one in 10{sup 16} decays. An observation of such a decay would be a clear sign of physics beyond the Standard Model. Achieving the targeted sensitivity requires a high precision detector with excellent momentum, vertex and time resolution. The Mu3e Tile Detector is a highly granular sub-detector system based on scintillator tiles with Silicon Photomultiplier (SiPM) readout, and aims at measuring the timing of the muon decay products with a resolution of better than 100 ps. This thesis describes the development of the Tile Detector concept and demonstrates the feasibility of the elaborated design. In this context, a comprehensive simulation framework has been developed, in order to study and optimise the detector performance. The central component of this framework is a detailed simulation of the SiPM response. The simulation model has been validated in several measurements and shows good agreement with the data. Furthermore, a 16-channel prototype of a Tile Detector module has been constructed and operated in an electron beam. In the beam tests, a time resolution up to 56 ps has been achieved, which surpasses the design goal. The simulation and measurement results demonstrate the feasibility of the developed Tile Detector design and show that the required detector performance can be achieved.

    Much recent research and funding have focused on building Internet-based repositories that contain collections of high-quality learning resources, often called learning objects. Yet little is known about how non-specialist users, in particular teachers, find, access, and use digital learning resources. To address this gap, this article describes a case study of mathematics and science teachers practices and desires surrounding the discovery, selection, and use of digital library resources for...

    Alterations in a variety of neurotransmitter systems have been identified in experimental models of epilepsy and in brain tissue from patients with intractable temporal lobe seizures. The availability of new high-affinity radioligands permits the study of some neuroreceptors in vivo with positron emission tomography (PET). We previously characterized the in vivo binding of 11C-carfentanil, a potent and selective mu opiate receptor agonist, and described increases in 11C-carfentanil binding in the temporal neocortex of patients with unilateral temporal lobe epilepsy. These studies have been extended to 11C-diprenorphine, which labels mu, kappa, and delta opiate receptor subtypes. Paired measurements of opiate receptor binding were performed with PET using 11C-carfentanil and 11C-diprenorphine in patients with unilateral temporal lobe seizures. Carfentanil binding, reflecting changes in mu opiate receptors, was increased in the temporal neocortex and decreased in the amygdala on the side of the epileptic focus. Diprenorphine binding, reflecting mu as well as non-mu opiate subtypes, was not significantly different among regions in the focus and nonfocus temporal lobes. Regional glucose metabolism, measured using 18F-2-fluoro-2-deoxyglucose, was decreased in the mesial and lateral aspects of the temporal lobe ipsilateral to the epileptogenic focus. The variation in pattern of carfentanil and diprenorphine binding supports a differential regulation of opiate subtypes in unilateral temporal lobe epilepsy.

    A search for the rare decays $B^0_s \\to \\mu^+\\mu^-$ and $B^0 \\to \\mu^+\\mu^-$ is performed using data collected in 2011 and 2012 with the LHCb experiment at the Large Hadron Collider. The data samples comprise 1.1 fb$^{-1}$ of proton-proton collisions at $\\sqrt{s}$ = 8 TeV and 1.0 fb$^{-1}$ at $\\sqrt{s}$=7 TeV. We observe an excess of $B^0_s \\to \\mu^+ \\mu^-$ candidates with respect to the background expectation. The probability that the background could produce such an excess or larger is 5.3 x 10$^{-4}$ corresponding to a signal significance of 3.5 standard deviations. A maximum-likelihood fit gives a branching fraction of $BR(B^0_s \\to \\mu^+ \\mu^-) = (3.2^{+1.5}_{-1.2})$ x $10^{-9}$, where the statistical uncertainty is 95% of the total uncertainty. This result is in agreement with the Standard Model expectation. The observed number of $B^0 \\to \\mu^+ \\mu^-$ candidates is consistent with the background expectation, giving an upper limit of $BR(B^0 \\to \\mu^+ mu^-) < 9.4$ x $10^{-10}$ at 95% confidence level...

  14. Study findings on evaluation of integrated family planning programme performance.

    1980-01-01

    In 1976 the United Nations's Economic and Social Commission for Asia and the Pacific launched a comparative study on integrated family planning programs in a number of countries in the region. In November 1979 the study directors from the participating countries meet in Bangkok to discuss the current status of the studies in their countries. The Korean and Malaysian studies were completed, the Bangladesh study was in the data collecting phase, and the Pakistani research design phase was completed. The meeting participants focused their attention on the findings and policy implications of the 2 completed studies and also discussed a number of theorectical and methodological issues which grew out of their research experience. The Malaysian study indicated that group structure, financial resources, and the frequency and quality of worker-client contact were the most significant variables determining program effectiveness. In the Korean Study, leadership, financial resources, and the frequency and quality of contact between agencies were the key variables in determining program effectiveness. In the Malaysian study there was a positive correlation between maternal and child health service performance measures and family planning service performance measures. This finding supported the contention that these 2 types of service provision are not in conflict with each other but instead serve to reinforce each other. Policy implications of the Korean study were 1) family planning should be an integral part of all community activities; 2) family planning workers should be adequately supported by financial and supply allocations; and 3) adequate record keeping and information exchange procedures should be incorporated in the programs.

    Sleep electroencephalographic (EEG) and computed tomographic (CT) features were examined in 40 institutionalized severely handicapped persons. Cranial CT appearance fell into five major types: (I) no abnormal findings (n=2), (II) generalized brain atrophy (n=16), (III) diffuse parenchymal disturbance (n=10), (IV) brain malformation (n=4), and (V) localized brain disturbance (n=8). In the I group, one person had normal EEG findings as well, but another person had the presence of focal spikes without spindles on EEG. Five of the II group had no abnormal EEG findings; ten had abnormality in basic waves and/or localized paroxysmal waves; and one had generalized spike-and-slow wave complex. All persons in the III group had flattening or disappearance of spindle waves. In the IV group, two persons with cerebral malformation and one with linear nevus sebaceous syndrome in association with hypoplasia of the cerebral hemisphere had abnormality in basic waves and localized paroxysmal waves. In the remaining one person with deficit of vermis cerebelli, there was no EEG abnormality. Among the last group of persons, there was no EEG abnormality corresponding to CT features. (Namekawa, K)

    Pediatric CT findings of acute appendicitis were reviewed retrospectively. The subjects were 29 patients (15 boys and 14 girls with an average age of 8.2 years), consisting of 17 with necrotic, 8 with phlegmonous inflammatory, and 4 with catarrhal appendicitis. CT findings were compared with the degree of inflammation. CT revealed abscess in 64.7%, 12.5%, and 0% for necrotic, phlegmonous inflammatory, and catarrhal types, respectively, and 41.4% for all types. An enlarged appendicitis was shown on CT in 86.2% (25/29). Fecalithes were shown on CT in 67.7% (19/29), which was associated with necrotic and phlegmonous inflammatory types, but not with catarrhal type. The other CT findings included thickened paramesocolon of the right lower abdomen, undefined wall of the inner side of the cecum. Inflammation was relatively slight in cases of catarrhal appendicitis, Nine patients less than 5 years of age had phlegmonous inflammatory or necrotic appendicitis. CT allowed definitive diagnosis of appendicitis in 2 of 3 patients with necrotic type. Ct was considered to be very useful in the diagnosis of appendicitis. (N.K.)

    Findings from a four year study by an international benchmarking group in the comparison of computational methods for evaluating burnup credit in criticality safety analyses are presented in this paper. Approximately 20 participants from 11 countries have provided results for most problems. Four detailed benchmark problems for Pressurized Water Reactor (PWR) fuel have been completed and are summarized in this paper. Preliminary results from current work addressing burnup credit for Boiling Water Reactor (BWR) fuel will also be discussed as well as planned activities for additional benchmarks including Mixed-Oxide (MOX) fuels, subcritical benchmarks, international databases, and other activities

    1983-01-01

    A new Electric Power Research Institute (EPRI) study of 26 nuclear projects shows a decrease in the leadtime for nuclear plants under construction in contrast to the findings of other studies. The EPRI study plots construction leadtime against the year of construction permit issuance rather than the year of completion, and it eliminates management delays, physical plant differences, and management differences. The result is a two-part trendline reflecting the discontinuity of regulatory ratchet effects, which cause 50% of construction leadtime delay while labor material delivery problems account for 20% and deliberate delays 22% of leadtime delay. When allowance is made for deliberate delays, there is no growth in construction leadtime. There was no correlation of utility finances, the accuracy of load growth forecasts, or the state regulatory environment to the length of construction. 3 figures,

  20. RECRUITING OLDER VOLUNTEERS: FINDINGS FROM THE BELGIAN AGEING STUDIES

    Full Text Available Although there is a significant body of work concerning voluntary work, hardly any attention is given to volunteering of older individuals. Moreover, the potential volunteers among older adults is even less examined. Next to volunteering among olde r adults, the neighbou rhood becomes more salient when people age and this due to their more intense use and time spent in the neighbourhood. In response to these lacunae, the main purpose of this contribution is to examine the impact of subjective neighbourhood features on the recruitment potential for volunteering among older people. This study uses data collected from the Belgian Ageing Studies. 59.977 adults aged sixty and over living self-reliantly in 127 Flemish municipalities in Belgium participated in this study. A binary logistic regression is ap plied to analyse the key va riables characterizing potential volunteers. Our findings stress the need for recognizing the crucial importance of the locality when recruiting older adults for volunteer activities.

    2012-01-01

    The decay Bs to mu+ mu- is one of the milestones of the flavor program at the LHC. We reappraise its Standard Model prediction. First, by analyzing the theoretical rate in the light of its main parametric dependence, we highlight the importance of a complete evaluation of higher-order electroweak corrections, at present known only in the large-mt limit, and leaving sizable dependence on the definition of electroweak parameters. Using insights from a complete calculation of such corrections for K to pi bar{nu} nu decays, we find a scheme in which NLO electroweak corrections are likely to be negligible. Second, we address the issue of the correspondence between the initial and the final state detected by the experiments, and those used in the theoretical prediction. Particular attention is devoted to the effect of the soft radiation, that has not been discussed for this mode in the previous literature, and that can lead to O(10%) corrections to the decay rate. The "non-radiative" branching ratio (that is equiva...

    Atypical squamous cells of undetermined significance (ASCUS) are a cervical cytologic finding category suggestive but not definitive of squamous intraepithelial lesions. ASCUS remains an incompletely described entity and accounts for even 5%-10% of reported Papanicolaou (Pap) smears. The management of women with such cytologic findings remains controversial. The aim of this study was to evaluate the cytology laboratory findings with regards to ASCUS diagnosis, using cervical Pap smears, and colposcopic biopsies, as well as their management. This is a retrospective study of patients with ASCUS Pap smears taken during the period January 2010 - December 2010 in the Second Department of Obstetrics and Gynecology, Aretaieion Hospital. During the study period, 657 Pap smears were examined at the Aretaieion Hospital; moreover, seven patients, whose Pap smears were cytologically diagnosed with ASCUS, were referred from other clinics, providing a total of 42 cases with a descriptive diagnosis of ASCUS for review. Of the 42 cases, eight were not studied because they were either lost in follow-up or they did not have available data. The remaining 34/42 patients were evaluated by colposcopic examination and directed biopsies where necessary. The ratio of ASCUS to low-grade squamous intraepithelial lesion (LGSIL), high-grade squamous cell intraepithelial lesion (HGSIL) or squamous cell carcinoma (SCC) was 5/34, 1/34, and 0/34, respectively. In the 34 ASCUS cases evaluated by colposcopy, the age distribution varied from 22 to 54 years. Eight of 34 cases did not have a child, 7/34 were primigravida, 18/34 were secondi-gravida, and 1/34 had four children. Four out of 34 cases were postmenopausal, 3/34 referred no history of abnormal bleeding, 21/34 were smokers, 6/34 used oral contraceptives, 2/34 used intrauterine devices, 1/34 took replacement of hormones, 4/34 had prior abnormal Pap smears human papillomavirus (HPV), or 1/34 had previous cancer (breast cancer). Colposcopy was

    The Planetary Science Division (PSD) within the National Aeronautics and Space Administrations (NASA) Science Mission Directorate (SMD) at NASA Headquarters sought to understand how to better realize a scientific return on spacecraft system technology investments currently being funded. In order to achieve this objective, a team at NASA Glenn Research Center was tasked with surveying the science and mission communities to collect their insight on technology infusion and additionally sought inputs from industry, universities, and other organizations involved with proposing for future PSD missions. This survey was undertaken by issuing a Request for Information (RFI) activity that requested input from the proposing community on present technology infusion efforts. The Technology Infusion Study was initiated in March 2013 with the release of the RFI request. The evaluation team compiled and assessed this input in order to provide PSD with recommendations on how to effectively infuse new spacecraft systems technologies that it develops into future competed missions enabling increased scientific discoveries, lower mission cost, or both. This team is comprised of personnel from the Radioisotope Power Systems (RPS) Program and the In-Space Propulsion Technology (ISPT) Program staff.The RFI survey covered two aspects of technology infusion: 1) General Insight, including: their assessment of barriers to technology infusion as related to infusion approach; technology readiness; information and documentation products; communication; integration considerations; interaction with technology development areas; cost-capped mission areas; risk considerations; system level impacts and implementation; and mission pull. 2) Specific technologies from the most recent PSD Announcements of Opportunities (AOs): The Advanced Stirling Radioisotope Generator (ASRG), aerocapture and aeroshell hardware technologies, the NASA Evolutionary Xenon Thruster (NEXT) ion propulsion system, and the

    Background: For women with breast cancer, the contralateral breast is at high risk. The bilateral cancers may be synchronous or metachronous. If the bilateral breast cancers have similar ultrasonography (US) appearances, the US findings of the first breast cancer (index cancer) might lead to early detection of the contralateral cancer. The purpose of this study was to identify the US characteristics of bilateral breast cancer and to determine whether bilateral breast cancers have similar US appearances and whether the US findings for one breast cancer might be predictive of the contralateral breast cancer. Methods: We retrospectively reviewed the US manifestations of 58 patients with surgically proven bilateral primary breast cancer and compared the contralateral cancer with the index cancer by evaluation the margin, shape, inside echoes, posterior attenuation, calcification and color flow signals of 58 lesion pairs to investigate whether the bilateral breast cancers have similar US appearances. Results: Bilateral primary breast cancers were more located in upper outer quadrant, frequently spiculation, taller than wide shape, with irregular margin, heterogeneous internal echo and acoustic shadowing, containing microcalcification and abundant color flow signals. The most common US appearances were taller than wide shape (75.0%, 87/116), irregular margins (79.3%, 92/116) and heterogeneous internal echo (86.2%, 100/116). Of the total 58 lesion pairs, 18 (31.0%) pairs had similar US characteristics, whereas 40 (69.0%) pairs had different US characteristics. Conclusions: US signs of the index cancer do not indicate the most likely appearance of the second cancer in the contralateral breast. Evaluation of the contralateral cancer should be performed without regard for the US findings for the index cancer

    We show that in theories where neutrino masses arise from type I seesaw formula with three right handed neutrinos and where large atmospheric mixing angle owes its origin to an approximate leptonic $\\mu-\\tau$ interchange symmetry, the primordial lepton asymmetry of the Universe, $\\epsilon_l$ can be expressed in a simple form in terms of low energy neutrino oscillation parameters as $\\epsilon_l = (a \\Delta m^2_\\odot+ b \\Delta m^2_A \\theta^2_{13})$, where $a$ and $b$ are parameters characterizing high scale physics and are each of order $\\leq 10^{-2} $ eV$^{-2}$. We also find that for the case of two right handed neutrinos, $\\epsilon_l \\propto \\theta^2_{13}$ as a result of which, the observed value of baryon to photon ratio implies a lower limit on $\\theta_{13}$. For specific choices of the CP phase $\\delta$ we find $\\theta_{13}$ is predicted to be between $0.10-0.15$.

    Transcriptional dysregulation in Huntington's disease (HD) is mediated in part by aberrant patterns of histone acetylation. We performed a dose-finding study in human HD of sodium phenylbutyrate (SPB), a histone deacetylase inhibitor that ameliorates the HD phenotype in animal models. We used a dose-escalation/de-escalation design, using prespecified toxicity criteria and standard clinical and laboratory safety measures. The maximum tolerated dose was 15 g/day. At higher doses, toxicity included vomiting, lightheadedness, confusion, and gait instability. We saw no significant laboratory or electrocardiographic abnormalities. Gene expression changes in blood suggested an inverse dose-response. In conclusion, SPB at 12 to 15 g/day appears to be safe and well-tolerated in human HD. 2007 Movement Disorder Society

  7. Sensitivity of dose-finding studies to observation errors.

    The purpose of Phase I designs is to estimate the MTD (maximum tolerated dose, in practice a dose with some given acceptable rate of toxicity) while, at the same time, minimizing the number of patients treated at doses too far removed from the MTD. Our purpose here is to investigate the sensitivity of conclusions from dose-finding designs to recording or observation errors. Certain toxicities may go undetected and, conversely, certain non-toxicities may be incorrectly recorded as dose-limiting toxicities. Recording inaccuracies would be expected to have an influence on final and within trial recommendations and, in this paper, we study in greater depth this question. We focus, in particular on three designs used currently; the standard '3+3' design, the grouped up-and-down design [M. Gezmu, N. Flournoy, Group up-and-down designs for dose finding. Journal of Statistical Planning and Inference 2006; 136 (6): 1749-1764.] and the continual reassessment method (CRM, [J. O'Quigley, M. Pepe, L. Fisher, Continual reassessment method: a practical design for phase 1 clinical trials in cancer. Biometrics 1990; 46 (1): 33-48.]). A non-toxicity incorrectly recorded as a toxicity (error of first kind) has a greater influence in general than the converse (error of second kind). These results are illustrated via figures which suggest that the standard '3+3' design in particular is sensitive to errors of the second kind. Such errors can have a very important impact on drug development in that, if carried through to the Phase 2 and Phase 3 studies, we can significantly increase the probability of failure to detect efficacy as a result of having delivered an inadequate dose.

  8. Industrial radioisotope economics. Findings of the study group

    International Nuclear Information System (INIS)

    1965-01-01

    Within twenty years of the availability of radioisotopes in quantity the use of these as tracers has been widely applied in scientific research and in industrial process and product control. Industry spends millions of dollars on these new techniques. Since the overall attitude of industry is to favour methods that involve rapid financial returns the economic benefits must be considerable. In promoting the peaceful uses of atomic energy, the IAEA is actively interested in the international exchange of experience in all applications of radioisotopes. This has been demonstrated by a number of scientific conferences where new results of direct importance to the industrial use of radioisotopes have been presented. In 1963 the IAEA also published literature survey on radioisotope applications described in the scientific literature up to 1960, classified according to industry. However, the available scientific literature was found insufficient to determine the extent of the use of radioisotopes and the economic benefits derived from it. Therefore, further fact-finding efforts were necessary. The IAEA thus decided to carry out an International Survey on the Use of Radioisotopes in Industry. In 1962 the IAEA's highly industrialized Member States Were invited to participate in the Survey; 25 declared their willingness to do so and in due course submitted their national reports. These included information on how radioisotopes were used by industry in each country and indicated the size and form of the economic advantages, primarily in terms of savings made by industry. The findings from the Survey were discussed at a Study Group Meeting on Radioisotope Economics, held in Vienna in March 1964. Forty participants from 22 countries were nominated for this Study Group. The program of the meeting was divided in three parts: (1) experience of the International Survey on the use of radioisotopes in industry; (2) present use of radioisotopes, technical and economic aspects; (3

    In this study the authors used semi-quantitative in vitro autoradiography to compare the levels of binding to central mu 1 , mu 2 , and delta opioid sites in two strains of mice, C57BL/6BY and CXBK. The CXBK strain is known to be deficient in whole brain opioid binding sites and to be less sensitive than the C57 strain to the analgesic and locomotor stimulatory effects of opiates and opioids. Delta sites were visualized using [ 3 H][D-Ala 2 -D-Leu 5 ]-enkephalin (DADL) plus a low concentration of morphine, total mu sites (mu 1 and mu 2 ) were visualized using [ 3 H]dihydromorphine (DHM), and mu 2 sites were visualized using [ 3 H]DHM plus a low concentration of DADL. Binding to mu 1 sites was determined by subtracting mu 2 binding from total mu binding. The authors found that the two strains did not consistently differ in the levels of delta sites. The CXBK strain, however, either had less or the same amount of mu binding as the C57 strain in all areas studied. The CXBK strain was especially deficient in mu 1 binding, particularly in areas involved in pain processing. (Auth.)

    A search for the $D^0\\to \\pi^+\\pi^-\\mu^+\\mu^-$ decay, where the muon pair does not originate from a resonance, is performed using proton-proton collision data corresponding to an integrated luminosity of $1.0\\mathrm{fb}^{-1}$ recorded by the LHCb experiment at a centre-of-mass energy of $7\\mathrm{TeV}$. No signal is observed and an upper limit on the relative branching fraction with respect to the resonant decay mode $D^0\\to \\pi^+\\pi^-\\phi(\\to\\mu^+\\mu^-)$, under the assumption of a phase-space model, is found to be \\begin{align} \\mathcal{B}(D^0\\to \\pi^+\\pi^-\\mu^+\\mu^-)/\\mathcal{B}(D^0\\to \\pi^+\\pi^-\\phi(\\to\\mu^+\\mu^-)) < 0.96\\\\ \\end{align} at the $90\\%$ confidence level. The upper limit on the absolute branching fraction is evaluated to be $\\mathcal{B}(D^0\\to \\pi^+\\pi^-\\mu^+\\mu^-) < 5.5 \\, \\times 10^{-7}$ at 90% confidence level. This is the most stringent to date.

    A search for the rare decays $B_s \\rightarrow \\mu^+ \\mu^-$ and $B_d \\rightarrow \\mu^+ \\mu^-$ is performed with data collected in 2011 and 2012 with the LHCb experiment at the Large Hadron Collider. The data samples comprise 1.1 fb$^{-1}$ of proton-proton collisions at $\\sqrt{s} = 8$ TeV and 1.0 fb$^{-1}$ at $\\sqrt{s}=7$ TeV. We observe an excess of $B_s \\rightarrow \\mu^+ \\mu^-$ candidates with respect to the background expectation. The probability that the background could produce such an excess or larger is $5.3\\times 10^{-4}$ corresponding to a signal significance of 3.5 standard deviations. A maximum-likelihood fit gives a branching fraction of $ {\\cal B} (B_s \\rightarrow \\mu^+ \\mu^-)$ = $(3.2^{\\,+1.5}_{\\,-1.2}) \\times 10^{-9}$, where the statistical uncertainty is 95 % of the total uncertainty. This result is in agreement with the Standard Model expectation. The observed number of $B^0 \\rightarrow \\mu^+ \\mu^-$ candidates is consistent with the background expectation, giving an upper limit of ${\\cal B}(B...

    Three highly specific opioid ligands--(D-Ala2,Gly-ol)-enkephalin (DAGO) for mu (mu) receptor sites, (D-Pen2,D-Pen5)-enkephalin (DPDPE) for delta (delta) sites, and U-69593 for kappa (kappa) sites--were used to determine the regional distribution of the three major subtypes of opioid receptor binding sites in the brains of 1-day-old domestic chicks by the technique of quantitative receptor autoradiography. While there was a degree of heterogeneity in the binding levels of each of the ligands, some notable similarities existed in the binding of the mu and kappa ligands in several forebrain regions, and in the optic tectum of the midbrain where mu and delta binding was very high. In the forebrain there was a high level of binding of mu and kappa ligands in the hyperstriatum, and for the mu ligand there was a very distinct lamination of binding sites in hyperstriatum accessorium, intercalatum supremum, dorsale and ventrale. Levels of binding of the mu and kappa ligands were also high in nucleus basalis, and (for mu only) in the neostriatum. The distribution of binding of the delta specific ligand in the forebrain showed marked differences to that of mu and kappa, being particularly low in the hyperstriatum and neostriatum. Very high levels of labelling of delta binding sites were, however, found in the nucleus rotundus. Binding of the three ligands was generally low or absent in the cerebellum and medulla, apart from a distinct labelling of the granule cell layer by the mu-ligand. A kinetic analysis was made of the binding of the three ligands to whole forebrain sections using scintillation counting methods.

    Almahata Sitta meteorites are unique polymict breccia, comprising of many different meteorite groups as individual fragments dominated by ureilite lithologies and are considered to be recovered fragments of the asteroid 2008TC3. Recently, two unusual Almahata Sitta samples (MS-MU-011 and MS-MU-012) have been reported that show close petrogenetic relationships to ureilites. MS-MU-011 is a trachyandesite mainly composed of feldspar (plagioclase and anorthoclase) and pyroxene (pigeonite and augite) having ureilitic oxygen isotopic ratios. MS-MU-012 is the first ureilite example (unbrecciated) containing primary plagioclase crystals. The findings of these two rock types are important to better understand formation conditions of ureilites and the evolution of their parent body(s). In this abstract we discuss formation conditions of these ureilite-related rocks using redox state estimate by Fe valence states of plagioclase and olivine cooling rate calculations.

    The increasing prevalence of overweight and obesity has become a key challenge for New Zealand. The purpose of the present study was to examine childhood risk factors for adult adiposity in a longitudinal birth cohort. Data were gathered from the Christchurch Health and Development Study (CHDS), a birth cohort of 1,265 children born in Christchurch in 1977. Associations were examined between socio-demographic background, perinatal factors, infant and child characteristics, family functioning/child maltreatment and adiposity at ages 30 and 35 years. Adiposity was assessed using body mass index scores. At ages 30 and 35, approximately one-third of cohort members were overweight and one-fifth were obese. Generalised estimating equation models showed that statistically significant (p<.05) predictors of later adiposity and overweight/obesity were: male gender, being born into a single-parent family, having parents with larger body size, higher early infant growth, limited or no breastfeeding, lower levels of cognitive ability and exposure to severe sexual abuse. Overweight and obesity was associated with social and family background, biological endowment, cognitive ability and childhood adversity factors. These findings may assist in the development of structured adiposity intervention programmes in conjunction with established community organisations specialising in child and family health.

    To highlight and illuminate the emotional sequelae of whistleblowing from whistleblowers and subjects of whistleblowing complaints. Whistleblowing has the potential to have a negative impact on individuals' physical and emotional well-being. However, few empirical studies have been conducted using qualitative methods to provide an in-depth exploration of the emotional consequences for those involved in whistleblowing incidents. Qualitative narrative inquiry design. Purposive sampling was used to recruit participants who had been involved in whistleblowing incidents. During interviews participants' accounts were digitally recorded and then transcribed verbatim. Data were then analysed by two researchers until consensus was reached. Findings revealed that participants' emotional health was considerably compromised as a result of the whistleblowing incident. Analysis of the data revealed the following dominant themes: 'I felt sad and depressed': overwhelming and persistent distress; 'I was having panic attacks and hyperventilating': acute anxiety; and, 'I had all this playing on my mind': nightmares, flashbacks and intrusive thoughts. While it has been previously acknowledged that whistleblowing has the potential to have a negative impact on all aspects of an individual's life, this study notably highlights the intensity of emotional symptoms suffered by participants as well as the extended duration of time these symptoms were apparent. As professionals, nurses, as well as organisations, have a responsibility to identify those who may be suffering the emotional trauma of whistleblowing and ensure they have access to appropriate resources. © 2011 Blackwell Publishing Ltd.

    Clinical, hematological and osseous effects following an intramuscular injection of 100 {mu}Ci 90 Sr were studied in the rat. In spite of the magnitude of the injection and the resulting damage, the elimination of strontium could compare with what occurs after an injection at tracer doses. Comparing with the controls at the outcoming time, clinical monitoring mainly brought out a loss of body weight. Fairly early (20. - 30. day) there occurred severe hematological damage, especially on lymphocyte line, which subsided spontaneously. As foreseen, the anatomo-pathological survey of the early period showed bone and medullar lesions in the areas of enchondral ossification. In the late period, bone sarcomas occurred in nine animals out of ten. The outstanding histological type was osteogenic osteosarcomas; besides, two animals experienced bilateral tumors.

    Full Text Available The paper explores properties of Łukasiewicz mu-calculus, a version of the quantitative/probabilistic modal mu-calculus containing both weak and strong conjunctions and disjunctions from Łukasiewicz (fuzzy logic. We show that this logic encodes the well-known probabilistic temporal logic PCTL. And we give a model-checking algorithm for computing the rational denotational value of a formula at any state in a finite rational probabilistic nondeterministic transition system.

    The aim of this study was to assess the role of videofluoroscopy in the detection of structural abnormalities of the pharynx and esophagus in patients with different symptoms of impaired deglutition. Dynamic radiographic recording of deglutition was performed in 3193 consecutive patients (1578 men, 1615 women; mean age 54 years) suffering from dysphagia, suspicion of aspiration, globus sensation, and non-cardiac chest pain. We assessed different structural lesions from the oral cavity to the esophagus and classified them into eight categories. Their frequency and association with the different clinical symptoms were evaluated. Videofluoroscopy revealed 1040 structural abnormalities in 833 patients (26%) including mass lesions from the oral cavity to hyoid/larynx (n=66), pharyngeal diverticula (n=181), pharyngeal masses (n=78), other pharyngeal narrowings (n=71), webs (n=98), masses (n=39), and other narrowings (n=73) of the upper esophageal sphincter, esophageal diverticula (n=80), esophageal webs, rings and strictures (n=194), and intrinsic and extrinsic esophageal lesions (n=160). There was a considerable variance of findings for different symptoms. In a large proportion of symptomatic patients videofluoroscopy detects morphological abnormalities along pharynx and esophagus often combined with functional disorders. This fact underlines the role of videofluoroscopy as a diagnostic test for function as well as morphology. (orig.)

    The ideal diagnostic methods in breast diseases consist of the physical examination and complementary radiologic examination. In radiologic examination mammography is the most popular screening methods and the older simple complementary method is thermography which is efficient under the conditions of elevated skin temperature in inflammatory and malignant lesions. From Jan. 1st 1987 through Jan. 30th, 1988, 110 pts. with complaints of mammary problems were examined by mammography and thermography at Paik Hospital, Inje University. The authors selected and analyzed 97 cases had been pathologically proved through the operation and the fine needle aspiration biopsy. The results were as follows: 1. The most prevalent age group was 5th decade (40%) in cancer, 4th decade (47%) in mammary dysplasia and followed by fibroadenoma (63%) in 4th decade. 2. The mammographic and thermographic findings were compared between the mammary dysplasia and the infiltrating ductal cancer. In mammary dysplasia abnormal hot emissions were appeared in 9/44 (17%) correlated with atypical hyperchromatic cytoplasm relates to pre-malignant group. 3. We hope and expect the early detection of breast cancer through the follow-up study in pre-malignant group of mammary dysplasia

    Problem This paper summarizes the findings on novice teenage driving outcomes (e.g., crashes and risky driving behaviors) from the Naturalistic Teenage Driving Study. Method Survey and driving data from a data acquisition system (Global Positioning System, accelerometers, cameras) were collected from 42 newly-licensed teenage drivers and their parents during the first 18 months of teenage licensure; stress responsivity was also measured in teenagers. Result Overall teenage crash and near crash (CNC) rates declined over time, but were >4 times higher among teenagers than adults. Contributing factors to teenage CNC rates included secondary task engagement (e.g., distraction), kinematic risky driving, low stress responsivity, and risky social norms. Conclusion The data support the contention that the high novice teenage CNC risk is due both to inexperience and risky driving behavior, particularly kinematic risky driving and secondary task engagement. Practical Applications Graduated driver licensing policy and other prevention efforts should focus on kinematic risky driving, secondary task engagement, and risky social norms. PMID:26403899

    A search for the decay Ks -> pi0 mu+ mu- has been made by the NA48/1 Colaboration at the CERN SPS accelerator. The data were collected during 2002 with a high intensity Ks beam. Six events were found with a background expectation of 0.22^+0.18_0.11 events. Using a vector matrix element and unit form factor, the measured branching ratio is B(Ks -> pi0 mu+ mu-) = [2.9^+1.5_1.2(stat) +- 0.2 (syst)] x 10^9.

    We search for the purely leptonic decay B{sup {+-}} {yields} {mu}{sup {+-}}{nu}{sub {mu}} in the full BABAR dataset, having an integrated luminosity of approximately 426 fb{sup -1}. We adopt a fully inclusive approach, where the signal candidate is identified by the highest momentum lepton in the event and the companion B is inclusively reconstructed without trying to identify its decay products. We set a preliminary upper limit on the branching fraction of {Beta}(B{sup {+-}} {yields} {mu}{sup {+-}}{nu}{sub {mu}}) < 1.3 x 10{sup -6} at the 90% confidence level, using a Bayesian approach.

    Mu suppression studies have been widely used to infer the activity of the human mirror neuron system (MNS) in a number of processes, ranging from action understanding, language, empathy and the development of autism spectrum disorders (ASDs). Although mu suppression is enjoying a resurgence of interest, it has a long history. This review aimed to revisit mu's past, and examine its recent use to investigate MNS involvement in language, social processes and ASDs. Mu suppression studies have largely failed to produce robust evidence for the role of the MNS in these domains. Several key potential shortcomings with the use and interpretation of mu suppression, documented in the older literature and highlighted by more recent reports, are explored here.

    The angular distributions and the partial branching fraction of the decay $B^{0} \\rightarrow K^{*0} \\mu^+ \\mu^-$ are studied using an integrated luminosity of $0.37\\,fb^{-1}$ of data collected with the LHCb detector. The forward-backward asymmetry of the muons, $A_{\\mathrm{FB}}$, the fraction of longitudinal polarisation, $F_{\\mathrm{L}}$, and the partial branching fraction, $\\mathrm{d}{\\mathcal B}/\\mathrm{d}q^{2}$, are determined as a function of the dimuon invariant mass. The measurements are in good agreement with the Standard Model predictions and are the most precise to date. In the dimuon invariant mass squared range $1.00-6.00{\\mathrm{\\,Ge\\kern -0.1em V}}^2/c^4$, the results are $A_{\\mathrm{FB}}=-0.06\\,^{+0.13}_{-0.14} \\pm 0.04$, $F_{\\mathrm{L}}=0.55\\pm 0.10\\pm 0.03$ and $\\mathrm{d}{\\mathcal B}/\\mathrm{d}q^{2}=(0.42 \\pm 0.06\\pm 0.03) \\times 10^{-7}c^4/{\\mathrm{\\,Ge\\kern -0.1em V}}^2$. In each case, the first error is statistical and the second systematic.

    Hicks, Emma; Shears, Tara

    LHCb is one of four main experiments at the LHC in CERN. This thesis analyses 1.03 fb$^{-1}$ of $\\sqrt{s} = 7$ TeV data collected in 2011. Measurements of the $Z\\rightarrow\\mu\\mu$ cross-section and a differential measurement with respect to $Z$ boson rapidity are presented. The primary motivations for making these measurements are to probe the accuracy of the Standard Model and constrain theoretical parton distribution functions. Final state radiation causes a downward shift in the reconstructed dimuon invariant mass and broadening in the peak. Reconstructing the radiated photon means the invariant mass distribution shift can be corrected for. Here final state radiation is implemented in LHCb simulation for the first time. It is used to study the effect on the reconstructed $Z$ mass distribution. Selections are placed on the distance between the photon and muon, and the photon $P_T$. The distribution is fitted to be 12% narrower than the non-reconstructed sample. The measured mass of the $Z$ boson is increase...

    The tau -> mu nu nu branching ratio has been measured using data collected from 1990 to 1995 by the OPAL detector at the LEP collider. The resulting value of B(tau -> mu nu nu) = 0.1734 +- 0.0009(stat) +- 0.0006(syst) has been used in conjunction with other OPAL measurements to test lepton universality, yielding the coupling constant ratios gmu/ge=1.0005+-0.0044 and gt/ge=1.0031+-0.0048, in good agreement with the Standard Model prediction of unity. A value for the Michel parameter eta = 0.004 +- 0.037 has also been determined and used to find a limit for the mass of the charged Higgs boson mH+- > 1.25 tan beta, in the Minimal Supersymmetric Standard Model.

    . Section 2 provides information on the overall study objectives; the organisational structure of the study and its Working Groups are described in Section 3. Section 4 describes the objectives of the individual Working Groups and summarises their key scientific and technical findings. Section 5 examines the extent to which the main objectives of the study have been fulfilled, assesses progress in generic aspects of biosphere modelling, summarises overall conclusions and implications, and provides suggestions for further work. The primary objectives of BIOMOVS II were threefold: 1. to test the accuracy of the predictions of environmental assessment models for selected contaminants and exposure scenarios; 2. to explain differences in model predictions due to differences in model structure, modelling assumptions and/or differences in selected input data; 3. to recommend priorities for future research to improve the accuracy of model predictions. A secondary objective of the study was to act as a forum for the exchange of ideas, experience and information in order to improve the confidence with which the behaviour of trace substances in the biosphere could be assessed quantitatively. It was the aim of BIOMOVS II that this forum should include modelers and other scientists working in the fields of safety assessment, radioecology, geology, climatology, etc, as well as experimentalists performing laboratory studies in these areas. In developing these objectives, additional objectives consistent with the background to the project were established within the individual themes addressed within BIOMOVS II. Notably, these included methodological developments for radiological assessments. Two different approaches were employed within BIOMOVS II for fulfilling these objectives. One approach to model testing, Approach A, involved the formulation of test scenarios based on suitable data and a comparison of model predictions against these independent data sets. The other approach, Approach

    The differential diagnosis of a dizzy patient >4 yrs old is often aided by videonystagmography (VNG) testing to provide a global assessment of peripheral and central vestibular function. Although the value of a VNG evaluation is well-established, it remains unclear if the VNG test battery is as applicable to the pediatric population as it is for adults. Oculomotor testing specifically, as opposed to spontaneous, positional, and caloric testing, is dependent upon neurologic function. Thus, age and corresponding neuromaturation may have a significant effect on oculomotor findings. The purpose of this investigation was to describe the effect of age on various tests of oculomotor function during a monocular VNG examination. Specifically, this study systematically characterized the impact of age on saccade tracking, smooth pursuit tracking, and optokinetic (OPK) nystagmus. The present study used a prospective, repeated measures design. A total of 62 healthy participants were evaluated. Group 1 consisted of 29 4- to 6-yr-olds. Group 2 consisted of 33 21- to 44-yr-olds. Each participant completed a standard VNG oculomotor test battery including saccades, smooth pursuit, and OPK testing in randomized order using a commercially available system. The response metrics saccade latency, accuracy, and speed, smooth pursuit gain, OPK nystagmus gain, speed and asymmetry ratios were collected and analyzed. Significant differences were noted between groups for saccade latency, smooth pursuit gain, and OPK asymmetry ratios. Saccade latency was significantly longer for the pediatric participants compared to the adult participants. Smooth pursuit gain was significantly less for the pediatric participants compared to the adult participants. The pediatric participants also demonstrated increased OPK asymmetry ratios compared to the adult participants. Significant differences were noted between the pediatric and adult participants for saccade latency, smooth pursuit gain, and OPK

    Magnetic resonance imaging in the brain was performed in 293 patients with childhood-onset (<15 y.o.) epilepsy who had been classified into 4 groups, idiopathic localization-related epilepsy (ILRE), 78 patients; idiopathic generalized epilepsy (IGE), 116 patients; symptomatic localization-related epilepsy (SLRE), 68 patients and symptomatic generalized epilepsy (SGE), 31 patients, with the Classification of Epilepsies and Epileptic Syndrome (1989 International League Against Epilepsy). The examination was performed with a 1.5 T magnet. One hundred twenty-five patients (42.7%) showed abnormal findings, and the incidence in each group was as follows: Idiopathic epilepsy: The rate of abnormal findings in the ILRE and IGE groups was 21.8% and 20.7%, respectively. Most of the abnormal findings were secondary changes, such as diffuse or localized brain atrophy. Of the congenital abnormalities, the main finding was arachnoid cyst. Symptomatic epilepsy: The rate of abnormality in the SLRE patients was 88.2%, and 85% of the findings were secondary changes, i.e., brain atrophy, or degeneration of the white matter. In the SGE group, the rate was 77.4%, with an almost equal percentage of congenital and secondary changes. Of 255 patients who were examined by electroencephalography (EEG) on the same day as MRI, about 50% showed a correlation between the EEG records and the MRI abnormalities. However, only 8 patients showed a correlation in localization between the EEG and MRI abnormalities. (author)

    Full Text Available BACKGROUND Nephrotic syndrome occurs when the filtering units of the kidneys- the glomeruli are damaged. The annual incidence of nephrotic syndrome ranges from 2-7 per 100,000 children. Oral corticosteroids form the cornerstone for management of most children with nephrotic syndrome. Long-term steroid therapy in childhood is associated with a number of significant adverse effectsmajor ophthalmic adverse effects include decreased vision, recurrent hordeolum, posterior subcapsular cataract, pseudotumour cerebri, visual hallucinations. This study aims to analyse the ocular findings in children with nephrotic syndrome, and their treatment related ocular abnormalities. MATERIALS AND METHODS This is a cross sectional study, conducted at The Department of Ophthalmology, Government Medical College Thrissur of 1-year duration. Study participants include patients who attended outpatient department of Paediatrics, Govt. Medical College, Thrissur, with clinical and objective investigational evidence of nephrotic syndrome. 70 children who were included in the study were interviewed with a questionnaire; Detailed history was taken from the patients and their parents, regarding the onset of the disease, treatment details, year of starting steroids, history of hypertension, additional drugs, history of defective vision, headache, allergic diseases of eye, eyelid swellings and use of spectacles. Visual acuity was assessed with Snellen s’ chart. Best corrected visual acuity was noted. Acuity was also measured with spectacles if the child was wearing them. Anterior segment was examined under torchlight and later in slit lamp and in all cases fundus examination and retinoscopy were done after dilating pupils with homatropine. Intraocular pressure was measured with Goldman Applanation Tonometer. RESULTS Since the sample size is small, the exact sex distribution cannot be ascertained. History of headache was present in 45 children (64.3%. Visual acuity was assessed

    Full Text Available Abstract Background The mu event-related desynchronization (ERD is supposed to reflect motor preparation and appear during motor imagery. The aim of this study is to examine the modulation of ERD with transcranial direct current stimulation (tDCS. Methods Six healthy subjects were asked to imagine their right hand grasping something after receiving a visual cue. Electroencephalograms (EEGs were recorded near the left M1. ERD of the mu rhythm (mu ERD by right hand motor imagery was measured. tDCS (10 min, 1 mA was used to modulate the cortical excitability of M1. Anodal, cathodal, and sham tDCS were tested in each subject with a randomized sequence on different days. Each condition was separated from the preceding one by more than 1 week in the same subject. Before and after tDCS, mu ERD was assessed. The motor thresholds (MT of the left M1 were also measured with transcranial magnetic stimulation. Results Mu ERD significantly increased after anodal stimulation, whereas it significantly decreased after cathodal stimulation. There was a significant correlation between mu ERD and MT. Conclusions Opposing effects on mu ERD based on the orientation of the stimulation suggest that mu ERD is affected by cortical excitability.

    MuSI, a gene that corresponds to a domain that contains the rubber elongation factor (REF), is highly homologous to many stress-related proteins in plants. Since MuSI is up-regulated in the roots of plants treated with cadmium or copper, the involvement of MuSI in cadmium tolerance was investigated in this study. Escherichia coli cells overexpressing MuSI were more resistant to Cd than wild-type cells transfected with vector alone. MuSI transgenic plants were also more resistant to Cd. MuSI transgenic tobacco plants absorbed less Cd than wild-type plants. Cd translocation from roots to shoots was reduced in the transgenic plants, thereby avoiding Cd toxicity. The number of short trichomes in the leaves of wild-type tobacco plants was increased by Cd treatment, while this was unchanged in MuSI transgenic tobacco. These results suggest that MuSI transgenic tobacco plants have enhanced tolerance to Cd via reduced Cd uptake and/or increased Cd immobilization in the roots, resulting in less Cd translocation to the shoots.

    The differential branching fraction of the rare decay $\\Lambda^{0}_{b} \\rightarrow \\Lambda^0 \\mu^+\\mu^-$ is measured as a function of $q^{2}$, the square of the dimuon invariant mass. The analysis is performed using proton-proton collision data, corresponding to an integrated luminosity of $3.0 \\mbox{ fb}^{-1}$, collected by the LHCb experiment. Evidence of signal is observed in the $q^2$ region below the square of the $J/\\psi$ mass. Integrating over $15 < q^{2} < 20 \\mbox{ GeV}^2/c^4$ the branching fraction is measured as $d\\mathcal{B}(\\Lambda^{0}_{b} \\rightarrow \\Lambda^0 \\mu^+\\mu^-)/dq^2 = (1.18 ^{+ 0.09} _{-0.08} \\pm 0.03 \\pm 0.27) \\times 10^{-7} ( \\mbox{GeV}^{2}/c^{4})^{-1}$, where the uncertainties are statistical, systematic and due to the normalisation mode, $\\Lambda^{0}_{b} \\rightarrow J/\\psi \\Lambda^0$, respectively. In the $q^2$ intervals where the signal is observed, angular distributions are studied and the forward-backward asymmetries in the dimuon ($A^{l}_{\\rm FB}$) and hadron ($A^{h}_{\\r...

    We revisit the calculation of the long-distance contribution to the muon-polarization asymmetry \\Delta_{LR}, which arises, in K^+\\to\\pi^+\\mu^+\\mu^-, from the two-photon intermediate state. The parity-violating amplitude of this process, induced by the local anomalous K^+\\pi^-\\gamma^*\\gamma^* transition, is analysed; unfortunately, one cannot expect to predict its contribution to the asymmetry by using chiral perturbation theory alone. Here we evaluate this amplitude and its contribution to \\Delta_{LR} by employing a phenomenological model called the FMV model, in which the utility of the vector and axial-vector resonances exchange is important to soften the ultraviolet behaviour of the transition. We find that the long-distance contribution is of the same order of magnitude as the standard model short-distance contribution.

    Objective: To assess the image findings of femoroacetabular impingement (FAI). Methods: Image findings of 9 patients with surgically proved femoroacetabular impingement were retrospectively reviewed for characteristic image findings of FAI. All 9 patients underwent X-ray examinations and MRI of affected hip, and 1 patient underwent MR arthrography (MRA) additionally. Results: X-ray examinations of all 9 patients showed bump at femoral head-neck junction or overcoverage of the acetabular. MRI showed various degrees of injury of anterosuperior labrum in all 9 patients. The injuries were stage Ⅰ A in 2 cases, stage Ⅰ B in 3, stage Ⅱ A in 2, and stage Ⅱ B in 2. MRA of the case showed tears of anterosuperior labrum, with contrast media entering into the teared labrum. There were sclerosis and cystic degeneration of subchondral bone of femoral head in 2 cases, and these findings were confirmed as cartilage delamination by surgery. Conclusions: MRI can display the injures of labrum and articular cartilage, which is helpful to the early diagnosis of' FAI. (authors)

    Much recent research and funding have focused on building Internet-based repositories that contain collections of high-quality learning resources, often called "learning objects." Yet little is known about how non-specialist users, in particular teachers, find, access, and use digital learning resources. To address this gap, this article…

    Full Text Available We aimed to investigate the mu rhythm in the sensorimotor area during tongue thrust observation and to obtain an answer to the question as to how subtle non-verbal orofacial movement observation activates the sensorimotor area. Ten healthy volunteers performed finger tap execution, tongue thrust execution, and tongue thrust observation. The electroencephalogram was recorded from 128 electrodes placed on the scalp, and regions of interest were set at sensorimotor areas. The event-related desynchronization (ERD and event-related synchronization (ERS for the mu rhythm (8–13 Hz and beta (13−25 Hz bands were measured. Tongue thrust observation induced mu rhythm ERD, and the ERD was detected at the left hemisphere regardless whether the observed tongue thrust was toward the left or right. Mu rhythm ERD was also recorded during tongue thrust execution. However, temporal analysis revealed that the ERD associated with tongue thrust observation preceded that associated with execution by approximately 2 s. Tongue thrust observation induces mu rhythm ERD in sensorimotor cortex with left hemispheric dominance.

    This thesis reports the branching fraction measurement of the rare Cabibbo-suppressed decay $\\Lambda_{b}\\rightarrow p\\pi^{-}\\mu^{+}\\mu^{-}$. The decay is observed for the first time with a $5.5\\sigma$ deviation from the background-only hypothesis. This is the first observation of a $b\\rightarrow d$ quark transition in the baryon sector. The dataset used for the measurement corresponds to 3 $\\mathrm{fb}^{-1}$ of $pp$ collisions collected at the LHCb experiment at CERN. The branching fraction is measured using $\\Lambda_{b}\\rightarrow J/\\psi(\\rightarrow\\mu^{+}\\mu^{-}) p \\pi^{-}$ as a normalisation channel and is measured as \\begin{equation*} \\mathcal{B}(\\Lambda_{b}\\rightarrow p\\pi^{-}\\mu^{+}\\mu^{-}) = (6.9 \\pm 1.9 \\pm 1.1^{+1.3}_{-1.0})\\times 10^{-8}, \\end{equation*} where the first error is the statistical uncertainty, the second is the systematic uncertainty and the third is the uncertainty on $\\mathcal{B}(\\Lambda_{b}\\rightarrow J/\\psi(\\rightarrow\\mu^{+}\\mu^{-}) p \\pi^{-})$.

    The study of kinetic isotope effects for H-atom abstraction rates by incident H-atoms from the homologous series of lower mass alkanes (CH4, C2H6 and, here, C3H8) provides important tests of reaction rate theory on polyatomic systems. With a mass of only 0.114 amu, the most sensitive test is provided by the rates of the Mu atom. Abstraction of H by Mu can be highly endoergic, due to the large zero-point energy shift in the MuH bond formed, which also gives rise to high activation energies from similar zero-point energy corrections at the transition state. Rates are then far too slow near 300 K to be measured by conventional TF-μSR techniques that follow the disappearance of the spin-polarised Mu atom with time. Reported here is the first measurement of a slow Mu reaction rate in the gas phase by the technique of diamagnetic radio frequency (RF) resonance, where the amplitude of the MuH product formed in the Mu + C3H8 reaction is followed with time. The measured rate constant, kMu = (6.8 ± 0.5) × 10(-16) cm(3) s(-1) at 300 K, is surprisingly only about a factor of three slower than that expected for H + C3H8, indicating a dominant contribution from quantum tunneling in the Mu reaction, consistent with elementary transition state theory calculations of the kMu/kH kinetic isotope effect.

In terms of the helicity amplitudes, we derive a compact form for the full angular distributions, through which the branching ratios, forward-backward asymmetries and polarizations are attained. We propose that the uncertainties in the B {yields} K{sup *}{sub J} form factors can be pinned down by the measurements of a set of SU(3)-related processes. Using results from the large energy limit, we derive the dependence of branching fractions on the m{sub K{pi}}, and find that the K{sup *}{sub 2} resonance has a clear signature, in particular, in the transverse polarizations.

    The muon as a laboratory for studying charged lepton-flavour violation (cLFV) has proven to be one of the most sensitive areas to probe for 'New Physics', due to the muon's copious production rate and relatively long lifetime. The search at the intensity frontier with precision-type experiments is complementary to the search for new particles at the high-energy frontier of TeV colliders. Of the three 'golden' muon channels: {mu} {yields} e{gamma}, {mu} {yields} 3e and {mu} {yields} econversion, an overview of the status of the coincidence experiments MEG, together with the latest results, which constitute the most stringent limit to date on this decay and the recently initiated Mu3e experiment, will be given.

    The reaction of mono- or dichloro-dimolybdenum(III) complexes [Mo2Cp2(mu-SMe)2(mu-Cl)(mu-Y)] (Cp=eta5-C5H5; 1, Y=SMe; 2, Y=PPh2; 3, Y=Cl) with NaBH4 at room temperature gave in high yields tetrahydroborato (8), hydrido (9) or metallaborane (12) complexes depending on the ancillary ligands. The correct formulation of derivatives and has been unambigously determined by X-ray diffraction methods. That of the hydrido compound 9 has been established in solution by NMR analysis and confirmed by an X-ray study of the mu-azavinylidene derivative [Mo2Cp2(mu-SMe)2(mu-PPh2)(mu-N=CHMe)] (10) obtained from the insertion of acetonitrile into the Mo-H bond of 9. Reaction of NaBH4 with nitrile derivatives, [Mo2Cp2(mu-SMe)4-n(CH3CN)2n]n+(5, n=1; 6 n=2), afforded the tetrahydroborato compound 8, together with a mu-azavinylidene species [Mo2Cp2(mu-SMe)3(mu-N=CHMe)](14), when n=1, and the metallaborane complex 12, together with a mixed borohydrato-azavinylidene derivative [Mo2Cp2(mu-SMe)2(mu-BH4)(mu-N=CHMe)] (13), when n=2. The molecular structures of these complexes have been confirmed by X-ray analysis. Preparations of some of the starting complexes (3 and 4) are also described, as are the molecular structures of the precursors [Mo2Cp2(mu-SMe)2(mu-X)(mu-Y)] (1, X/Y=Cl/SMe; 2, X/Y=Cl/PPh2; 4, X/Y=SMe/PPh2).

    The mechanisms of dinitrogen hydrogenation by two different complexes--[(eta(5)-C(5)Me(4)H)(2)Zr](2)(mu(2),eta(2),eta(2)-N(2)), synthesized by Chirik and co-workers [Nature 2004, 427, 527], and {[P(2)N(2)]Zr}(2)(mu(2),eta(2),eta(2)-N(2)), where P(2)N(2) = PhP(CH(2)SiMe(2)NSiMe(2)CH(2))(2)PPh, synthesized by Fryzuk and co-workers [Science 1997, 275, 1445]--are compared with density functional theory calculations. The former complex is experimentally known to be capable of adding more than one H(2) molecule to the side-on coordinated N(2) molecule, while the latter does not add more than one H(2). We have shown that the observed difference in the reactivity of these dizirconium complexes is caused by the fact that the former ligand environment is more rigid than the latter. As a result, the addition of the first H(2) molecule leads to two different products: a non-H-bridged intermediate for the Chirik-type complex and a H-bridged intermediate for the Fryzuk-type complex. The non-H-bridged intermediate requires a smaller energy barrier for the second H(2) addition than the H-bridged intermediate. We have also examined the effect of different numbers of methyl substituents in [(eta(5)-C(5)Me(n)H(5)(-)(n))(2)Zr](2)(mu(2),eta(2),eta(2)-N(2)) for n = 0, 4, and 5 (n = 5 is hypothetical) and [(eta(5)-C(5)H(2)-1,2,4-Me(3))(eta(5)-C(5)Me(5))(2)Zr](2)(mu(2),eta(2),eta(2)-N(2)) and have shown that all complexes of this type would follow a similar H(2) addition mechanism. We have also performed an extensive analysis on the factors (side-on coordination of N(2) to two Zr centers, availability of the frontier orbitals with appropriate symmetry, and inflexibility of the catalyst ligand environment) that are required for successful hydrogenation of the coordinated dinitrogen.

    A measurement of the $C\\!P$ asymmetry in $B^0 \\rightarrow K^{*0} \\mu^+ \\mu^-$ decays is presented, based on 1.0 fb$^{-1}$ of $pp$ collision data recorded by the LHCb experiment during 2011. The measurement is performed in six bins of invariant mass squared of the $\\mu^+\\mu^-$ pair, excluding the $\\mathrm{J}\\mskip -3mu/\\mskip -2mu\\psi\\mskip 2mu$ and $\\psi(2S)$ resonance regions. Production and detection asymmetries are removed using the $B^0 \\rightarrow \\mathrm{J}\\mskip -3mu/\\mskip -2mu\\psi\\mskip 2mu K^{*0}$ decay as a control mode. The integrated $C\\!P$ asymmetry is found to be $-0.072 \\pm 0.040 \\mbox{ (stat.)} \\pm 0.005 \\mbox{ (syst.)}$, consistent with the Standard Model.

  17. The Small Magellanic Cloud in the far infrared. I. ISO's 170 mu m map and revisit of the IRAS 12-100 mu m data

    The ISOPHOT experiment onboard the ISO satellite generated a complete view of the Small Magellanic Cloud (SMC) at 170 mu m with 1.5 arcmin resolution. The map is analysed using an automated photometry program enabling accurate photometric characterization of the far infrared (FIR) emitting regions. An integrated FIR luminosity of 8.5x 107 Lsun is obtained, leading to a star formation rate of SFRFIR=0.015 Msun/yr. With an average dust temperature of TD, 170/100}=20.5 K>, the total dust mass follows to MD=3.7x105 Msun. In this paper, the sources detected at 170 mu m are compared with those obtainable from the IRAS satellite data. For this purpose, the 12 mu m, 25 mu m, 60 mu m, and 100 mu m IRAS high resolution (HiRes) maps of the SMC are re-examined using the same method. In contrast to former studies, this provides an all-band ISO/IRAS source catalog which is no longer based on eyeball classification, but relies on an algorithm which is capable of automated, repeatable photometry, even for irregular sources. In the mid infrared IRAS bands numerous bright FIR emitting regions in the SMC are detected and classified: 73 sources are found at 12 mu m, 135 at 25 mu m (most of them with Fnu =2.0 Jy. Comparable numbers are found for the two FIR IRAS maps at 60 mu m (384) and 100 mu m (338) with fluxes up to 450 Jy. 70 of the 243 170 mu m sources are assigned a general SED type (``cold'', ``warm'', i.e., 30 K) for the first time. A comparison with earlier IRAS results suggests that many source flux densities in those studies have been under- or overestimated because of non-standardized fitting methods. Many sources with flux densities up to 40 Jy listed in former catalogs cannot be identified in our data.

  18. Musical training increases functional connectivity, but does not enhance mu suppression.

    Musical training provides an ideal platform for investigating action representation for sound. Learning to play an instrument requires integration of sensory and motor perception-action processes. Functional neuroimaging studies have indicated that listening to trained music can result in the activity in premotor areas, even after a short period of training. These studies suggest that action representation systems are heavily dependent on specific sensorimotor experience. However, others suggest that because humans naturally move to music, sensorimotor training is not necessary and there is a more general action representation for music. We previously demonstrated that EEG mu suppression, commonly implemented to demonstrate mirror-neuron-like action representation while observing movements, can also index action representations for sounds in pianists. The current study extends these findings to a group of non-musicians who learned to play randomised sequences on a piano, in order to acquire specific sound-action mappings for the five fingers of their right hand. We investigated training-related changes in neural dynamics as indexed by mu suppression and task-related coherence measures. To test the specificity of training effects, we included sounds similar to those encountered in the training and additionally rhythm sequences. We found no effect of training on mu suppression between pre- and post-training EEG recordings. However, task-related coherence indexing functional connectivity between electrodes over audiomotor areas increased after training. These results suggest that long-term training in musicians and short-term training in novices may be associated with different stages of audiomotor integration that can be reflected in different EEG measures. Furthermore, the changes in functional connectivity were specifically found for piano tones, and were not apparent when participants listened to rhythms, indicating some degree of specificity related to training

    The discovery of a new class of superconducting materials, ReFeAsO{sub 1-x}F{sub x}, stirred up the scientific community. Here we report the Gd{sup 3+} high field ESR study of differently doped (La,Gd)FeAsO{sub 1-x}F{sub x} compounds. In lightly Gd-doped LaFeAsO samples the SDW transition yields line-broadening at the transition temperature, the SDW transition is then suppressed upon F-doping. In the dense compound, GdFeAsO, with SDW transition around 140 K, the Gd-ESR was also studied. With 15% F-doping superconductivity appears at {proportional_to} 21 K. The SDW and SC transitions are clearly seen in ESR and in {mu} SR as well. Surprisingly the reminiscence of the SDW transition of the undoped material (GdFeAsO) was identified in the doped (15% F) compound at lower temperature ({proportional_to} 80 K). This indicates the importance of the the interplay between superconductivity and magnetism in oxypnictides.

    Full Text Available Introduction: Association between single-nucleotide polymorphisms (SNPs in mu opioid receptor gene and drug addiction has been shown in various studies. Here, we have evaluated the existence of polymorphisms in exon 3 of this gene in Iranian population and investigated the possible association between these mutations and opioid addiction.  Methods: 79 opioid-dependent subjects (55 males, 24 females and 134 non-addict or control individuals (74 males, 60 females participated in the study. Genomic DNA was extracted from volunteers’ peripheral blood and exon 3 of the mu opioid receptor gene was amplified by polymerase chain reaction (PCR whose products were then sequenced.  Results: Three different heterozygote polymorphisms were observed in 3 male individuals: 759T>C and 877G>A mutations were found in 2 control volunteers and 1043G>C substitution was observed in an opioid-addicted subject. Association between genotype and opioid addiction for each mutation was not statistically significant.  Discussion: It seems that the sample size used in our study is not enough to confirm or reject any association between 759T>C, 877G>A and 1043G>C substitutions in exon 3 of the mu opioid receptor gene and opioid addiction susceptibility in Iranian population.

    Hypnosis modulates pain perception and tolerance by affecting cortical and subcortical activity in brain regions involved in these processes. By reviewing functional neuroimaging studies focusing on pain perception under hypnosis, the authors aimed to identify brain activation-deactivation patterns occurring in hypnosis-modulated pain conditions. Different changes in brain functionality occurred throughout all components of the pain network and other brain areas. The anterior cingulate cortex appears to be central in modulating pain circuitry activity under hypnosis. Most studies also showed that the neural functions of the prefrontal, insular, and somatosensory cortices are consistently modified during hypnosis-modulated pain conditions. Functional neuroimaging studies support the clinical use of hypnosis in the management of pain conditions.

    The Nun Study is a longitudinal study of 678 Catholic sisters 75 to 107 years of age who are members of the School Sisters of Notre Dame congregation. Data collected for this study include early and middle-life risk factors from the convent archives, annual cognitive and physical function evaluations during old age, and postmortem neuropathologic evaluations of the participants' brains. The case histories presented include a centenarian who was a model of healthy aging, a 92-year-old with dementia and clinically significant Alzheimer disease neuropathology and vascular lesions, a cognitively and physically intact centenarian with almost no neuropathology, and an 85-year-old with well-preserved cognitive and physical function despite a genetic predisposition to Alzheimer disease and an abundance of Alzheimer disease lesions. These case histories provide examples of how healthy aging and dementia relate to the degree of pathology present in the brain and the level of resistance to the clinical expression of the neuropathology.

    Intradermal delivery of vaccines has been shown to result in dose sparing. We tested the ability of fractional doses of inactivated poliovirus vaccine (IPV) delivered intradermally to induce levels of serum poliovirus-neutralizing antibodies similar to immunization through the intramuscular route. Immunogenicity of fractional doses of IPV was studied by comparing intramuscular and intradermal immunization of Wistar rats using NanoPass MicronJet600 microneedles. Intradermal delivery of partial...

    This study qualitatively explores perceptions of women who have experienced abortion care. It explores women's journey through abortion from confirmation of pregnancy to post-abortion. The study seeks to understand the implications of these perceptions for policy and practice. A qualitative study involving in-depth semi-structured interviews with 17 women, aged between 22 and 57 years, who had undergone legal induced abortion in the UK when they were 16 years or older. Participants were not recruited under the age of 16 because of the ethical and legal complexities of interviewing minors. Additionally, 16 years was deemed to be the most appropriate age as this is the legal age of consent in the UK. Participants were recruited from 12 community contraception and sexual health clinics in two NHS trusts, one in England and one in Wales. Participant recruitment was set at a minimum of 12 and participants were recruited on a "first come first served basis" (i.e., the first 12 who contacted the researcher). The number of participants was raised to seventeen as this was the number deemed to be the most suitable for data saturation in this particular qualitative research. Women in this study understood abortion as highly taboo and a potentially personally stigmatizing event. These perceptions continued to affect disclosure to others, long after the abortion, and affected women's perceptions of the response of others, including society in general, significant others, and health professionals. Women's experiences of abortion may be influenced by perceived negative social attitudes. Health professionals and abortion service providers might combat the perceived isolation of women undergoing abortion by attending not only to clinical/technical aspects of the procedure but also to women's psychological/emotional sensitivities surrounding the event. © 2012 International Society for Sexual Medicine.

  13. Studies of Expansive Learning: Foundations, Findings and Future Challenges

    Full Text Available The paper examines studies based on the theory of expansive learning, formulated in 1987. In recent years the theory has been used in a wide variety of studies and interventions. The theory builds on foundational ideas put forward by Vygotsky, Leont’ev, Il’enkov, and Davydov, key figures in the Russian school of cultural-historical activity theory. Studies based on the theory are reviewed in six sections: expansive learning as transformation of the object, expansive learning as movement in the zone of proximal development, expansive learning as cycles of learning actions, expansive learning as boundary crossing and network building, expansive learning as distributed and discontinuous movement, and formative interventions.A separate section is devoted to critiques of expansive learning. It is concluded that the ultimate test of learning theories is how they help practitioners to generate learning that grasps pressing issues the humankind is facing. The theory of expansive learning currently expands its analyses both up and down, outward and inward. Moving up and outward, it tackles learning in fields or networks of interconnected activity systems with their partially shared and often contested objects. Moving down and inward, it tackles issues of subjectivity, experiencing, personal sense, emotion, embodiment, identity, and moral commitment.

    Full Text Available Background: Cardiac manifestations that occur in a majority of patients with organophosphate (OP poisoning may range from innocuous electrocardiographic manifestations, such as sinus tachycardia, to life-threatening complications, including cardiogenic pulmonary edema and myocardial necrosis. In this study, we evaluated the various electrocardiographic manifestations in patients with OP poisoning. Methods: This retrospective-descriptive study was performed by reviewing the medical records from all patients poisoned with organophosphate admitted to Razi Educational Hospital, Rasht, Iran, from April 2008 to March 2011. Patients with incomplete records were excluded from the study. Histories of all patients were collected and ECG analysis was conducted including the rate, rhythm, ST-T abnormalities, conduction defects, and measurement of PR and QT intervals by a cardiologist. Descriptive statistical analysis was conducted by SPSS software version18. Results: Of the total 100 patients (75 were male with OP poisoning that referred to the Emergency Ward of Razi Hospital, 63 patients presented ECG abnormalities. The mean age of the patients was 35.78 ± 12.91 years. The causes of poisoning were occupational in 71 patients, suicidal in 26 patients, and accidental in 3 patients. Sinus tachycardia (31% was the most common ECG abnormality, followed by non-specific ST-T changes (24%. Overall, mortality rate was 5% and all of the deceased patients presented changes in ECG. Conclusion: OP poisoning is associated with significant ECG abnormalities, especially tachycardia and non-specific ST-T changes.

    As part of its examination of federal support for immunization services during the past decade, the Institute of Medicine (IOM) Committee on Immunization Finance Policies and Practices (IFPP) commissioned eight case studies of the states of Alabama, Maine, Michigan, New Jersey, North Carolina, Texas, and Washington; and a two-county study of Los Angeles and San Diego in California. Specifically, the IOM Committee and these studies reviewed the use of Section 317 grants by the states. Section 317 is a discretionary grant program that supports vaccine purchase and other immunization-related program activities. These studies afforded the Committee an in-depth look at local policy choices, the performance of immunization programs, and federal and state spending for immunization during the past decade. The case-study reports were developed through interviews with state and local health department officials, including immunization program directors, Medicaid agency staff, budget analysts, and Centers for Disease Control and Prevention public health advisors to the jurisdiction. Other sources included state and federal administrative records and secondary sources on background factors and state-level trends. The case studies were supplemented by site visits to Detroit, Houston, Los Angeles, Newark, and San Diego. The nature of immunization "infrastructure" supported by the Section 317 program is shifting from primarily service delivery to a broader set of roles that puts the public effort at the head of a broad immunization partnership among public health, health financing, and other entities in both the public and private sectors. The rate and intensity of transition vary across the case-study areas. In the emerging pattern, service delivery increasingly takes place in the private sector and is related to managed care. "Infrastructure" is moving beyond supporting a core state staff and local health department service delivery to include such activities as immunization

    Somatising tendency, defined as a predisposition to worry about common somatic symptoms, is importantly associated with various aspects of health and health-related behaviour, including musculoskeletal pain and associated disability. To explore its epidemiological characteristics, and how it can be specified most efficiently, we analysed data from an international longitudinal study. A baseline questionnaire, which included questions from the Brief Symptom Inventory about seven common symptoms, was completed by 12,072 participants aged 20-59 from 46 occupational groups in 18 countries (response rate 70%). The seven symptoms were all mutually associated (odds ratios for pairwise associations 3.4 to 9.3), and each contributed to a measure of somatising tendency that exhibited an exposure-response relationship both with multi-site pain (prevalence rate ratios up to six), and also with sickness absence for non-musculoskeletal reasons. In most participants, the level of somatising tendency was little changed when reassessed after a mean interval of 14 months (75% having a change of 0 or 1 in their symptom count), although the specific symptoms reported at follow-up often differed from those at baseline. Somatising tendency was more common in women than men, especially at older ages, and varied markedly across the 46 occupational groups studied, with higher rates in South and Central America. It was weakly associated with smoking, but not with level of education. Our study supports the use of questions from the Brief Symptom Inventory as a method for measuring somatising tendency, and suggests that in adults of working age, it is a fairly stable trait.

  19. Findings of the Marshall Islands nationwide radiological study

    Full text: The Marshall Islands were affected by nuclear weapon tests carried out over the period 1946-1958, and particularly from the Bravo detonation on 1 March 1954, which deposited heavy fallout on the islands of Rongelap atoll about 100 miles to the east of Bikini. Surveys of residual radioactivity of the northern atolls of the Marshalls group had been carried out by the US Department of Energy, but continuing concerns about health effects of exposure to fallout, particularly thyroid disease, led the Marshall Islands government in 1989 to set up a study of residual radioactivity across the entire country. A study of residual radioactivity on all significant atolls and islands was carried out by ground surveys during 1990-94. The study was supervised by an international panel of 5 non US scientists. The measurements included portable gamma spectrometer measurements at points on a grid pattern, with associated soil samples and periodic soil profile and vegetation samples. From these measurements external exposure rates from deposited fallout have been calculated, and estimates made of the ingestion doses which might be received by resident populations consuming diets made up of differing amounts of locally produced foodstuffs. On the basis of a survey of dietary intake by a Rongelap community a current diet (containing 18% of foods from local sources) and a more traditional diet (75% from local sources) were used for comparison purposes. Measurements were made on 432 islands of the 29 atolls and 5 islands that make up the Marshalls group. Atolls in the latitude range 9-12 degrees north have Cs-137 soil concentrations which are elevated above levels expected from global fallout. Over 90% of the radiation dose from residual fallout is attributable to Cs-137, and arises primarily from dietary intake. Doses to actual or hypothetical residents are about 4 times greater for traditional as compared with current diets. For four atolls there are some islands where

Several angular observables are measured in bins of the dimuon invariant mass squared, $q^{2}$. A first measurement of the zero-crossing point of the forward-backward asymmetry of the dimuon system is also presented. The zero-crossing point is measured to be $q_{0}^{2} = 4.9 \\pm 0.9 \\,{\\rm GeV}^{2}/c^{4}$, where the uncertainty is the sum of statistical and systematic uncertainties. The results are consistent with the Standard Model predictions.

    Intradermal delivery of vaccines has been shown to result in dose sparing. We tested the ability of fractional doses of inactivated poliovirus vaccine (IPV) delivered intradermally to induce levels of serum poliovirus-neutralizing antibodies similar to immunization through the intramuscular route. Immunogenicity of fractional doses of IPV was studied by comparing intramuscular and intradermal immunization of Wistar rats using NanoPass MicronJet600 microneedles. Intradermal delivery of partial vaccine doses induced antibodies at titers comparable to those after immunization with full human dose delivered intramuscularly. The results suggest that intradermal delivery of IPV may lead to dose-sparing effect and reduction of the vaccination cost.

    In order to gain more insight into the specific behavior of materials, it is often necessary to perform measurements as a function of different external parameters. Despite its high sensitivity to internal fields, this simple observation also applies for the {mu}SR technique. The most common parameter which can be tuned during an experiment is the sample temperature. By using a range of cryostats, temperatures between 0.02 and 900 K can be covered at the PSI {mu}SR Facility. On the other hand, and by using high-energy muons, pressures as high as 10'000 bars can nowadays be reached during {mu}SR experiments. As will be demonstrated in the following Sections, the magnetic field is an additional external parameter playing a fundamental role when studying the ground state properties of materials in condensed matter physics and chemistry. However, the availability of high magnetic fields for {mu}SR experiments is still rather limited. Hence, if on one hand the high value of the gyromagnetic ratio of the muon provides the high magnetic sensitivity of the method, on the other hand it can lead to very high muon-spin precession frequencies when performing measurements in applied fields (the muon-spin precession frequency in a field of 1 Tesla s 135.5 MHz). Consequently, the use of ultra-fast detectors and electronics is mandatory when measuring in magnetic fields exceeding 1 Tesla. If such fields are very intense when compared to the Earth magnetic field < 10{sup -4} Tesla), the energy associated with them is still modest in view of the thermal energy. Hence, the Zeeman energy splitting of a free electron in a magnetic field of 1 Tesla corresponds to a thermal energy as low as 0.67 Kelvin. It is worth mentioning that nowadays magnetic fields of the order of 10 to 15 Tesla are quite common in condensed matter laboratories and have opened up vast new exciting experimental possibilities.

    A search for heavy Majorana neutrinos produced in the $B^- \\to \\pi^+\\mu^-\\mu^-$ decay mode is performed using 3 fb$^{-1}$ of integrated luminosity collected with the LHCb detector in $pp$ collisions at center-of-mass energies of 7 TeV and 8 TeV at the LHC. Neutrinos with masses in the range 250-5000 MeV and lifetimes from zero to 1000 ps are probed. In the absence of a signal, upper limits are set on the branching fraction ${\\cal{B}}(B^- \\to \\pi^+\\mu^-\\mu^-)$ as functions of neutrino mass and lifetime. These limits are on the order of $10^{-9}$ for short neutrino lifetimes of 1 ps or less. Limits are also set on the coupling between the muon and a possible fourth-generation neutrino.

    Full Text Available Background: Hypertension prevention and control are among the most important public health priorities. We evaluated the impacts of a workplace intervention project "Stop Hypertension in Mobarakeh Steel Company" (SHIMSCO on controlling hypertension in industrial workers. Methods: The study was carried out in Mobarakeh Steel Company in Isfahan among 7286 male workers and employees. All individuals were evaluated for the presence of hypertension (HTN. According to examinations, 500 subjects with  systolic blood pressure (SBP ≥ 140 mmHg, and/or diastolic blood pressure (DBP ≥ 90 mmHg, and/or those using antihypertensive medications were confirmed to have HTN and thus included in this study. They were questioned for sociodemographic characteristics, past medical history and medication use. They received an educational program including healthy lifestyle and self-care recommendations of HTN management and control as well as training for accurate blood pressure measurement and home monitoring for two years. SBP, DBP, weight, height and routine lab tests were measured for all hypertensive subjects before and after the interventions. Paired t-test, generalized estimation equation (GEE and ordinary linear regression (OLR were used for statistical analysis in SPSS. Results: The comparison of SBP and DBP before and after the educational program showed significant reductions in both parameters (-7.97 ± 14.72 and -2.66 ± 9.96 mmHg, respectively. However, a greater decrease was detected in case of DBP. GEE showed SBP and DBP to decrease about -0.115 and -0.054 mmHg/month. OLR also revealed reductions of 4.88 and 2.57 mmHg respectively in SBP and DBP upon adding each antihypertensive drug. Conclusion: SHIMSCO, a 3-year interventional project in workplaces, was effective in reducing SBP and DBP among hypertensive employees and workers. We conclude that implementing simple educational programs in worksites can improve the management and control of

    The hypothesis that personality characteristics in adolescence can be used to predict religiousness and spiritual seeking in late adulthood was tested using a structural equation modeling framework to estimate cross-lagged and autoregressive effects in a two-wave panel design. The sample consisted of 209 men and women participants in the Berkeley Guidance and Oakland Growth studies. In late adulthood, religiousness was positively related to Conscientiousness and Agreeableness, and spiritual seeking was related to Openness to Experience. Longitudinal models indicated that Conscientiousness in adolescence significantly predicted religiousness in late adulthood above and beyond adolescent religiousness. Similarly, Openness in adolescence predicted spiritual seeking in late adulthood. The converse effect, adolescent religiousness to personality in late adulthood, was not significant in either model. Among women, adolescent Agreeableness predicted late-life religiousness and adolescent religiousness predicted late-life Agreeableness; both these effects were absent among men. Adolescent personality appears to shape late-life religiousness and spiritual seeking independent of early religious socialization.

    Work on longevity has found protective social, cognitive, and emotional factors, but to date we have little understanding of the impact of motivational dynamics. Autonomy orientation, or stable patterns of self-regulation, is theorized to be a protective factor for long-term mental and physical health (Ryan & Deci, 2017), and it is therefore a prime candidate for examining how stable psychosocial factors are linked to longevity, or life expectancy. Essays written in the 1930s by participants in the Nun Study were coded for indicators of an autonomy orientation. These were selected in line with an extensive theoretical literature based in self-determination theory (Deci & Ryan, 1985). Essays were coded for the propensity for choice in action, susceptibility to pressure, self-reflection, integration of experiences, and parental support for autonomy. These coded variables were used to predict age of death. Using 176 codable essays provided by now-deceased participants, linear regression analyses revealed that choiceful behavior, self-reflection, and parent autonomy support predicted age of death. Participants who demonstrated these stable and beneficial motivational characteristics lived longer. Personality constructs reflecting a healthy form of self-regulation are associated with long-term health. Implications for health interventions are discussed. © 2018 The Authors.

  9. Competitiveness of nuclear energy - Key findings from an OECD study

    2006-01-01

    Economic competitiveness always has been a cornerstone in decision making for electricity generation options but the liberalization of energy markets has enhanced its importance. For private investors in de-regulated markets the economic attractiveness of a project is often 'the' driving factor. For plant owners and operators reducing costs is a key objective. The relative competitiveness of nuclear energy as compared with alternatives has been investigated in a recent OECD study which noted some evolution in the ranking of different options as compared with results published seven years ago. In particular the volatility of fossil fuel prices, notably natural gas for electricity generation, along with technical progress enhancing the reliability and availability factor of nuclear power plants have had a significant influence on comparative economic performance of base-load options. Furthermore, as governments implement progressively policies to address global climate change threat, the moves to internalize the costs of carbon emissions is increasing the competitiveness of low-carbon options such as renewable energy sources and nuclear power versus coal and to a lesser extent gas.

    To explore clinician and family experiences of conflict in paediatric services, in order to map the trajectory of conflict escalation. Qualitative interview study, employing extreme-case sampling. Interviews were analysed using an iterative thematic approach to identify common themes regarding the experience and escalation of conflict. Thirty-eight health professionals and eight parents. All participants had direct experience of conflict, including physical assault and court proceedings, at the interface of acute and palliative care. Two teaching hospitals, one district general hospital and two paediatric hospices in England, in 2011. Conflicts escalate in a predictable manner. Clearly identifiable behaviours by both clinicians and parents are defined as mild, moderate and severe. Mild describes features like the insensitive use of language and a history of unresolved conflict. Moderate involves a deterioration of trust, and a breakdown of communication and relationships. Severe marks disintegration of working relationships, characterised by behavioural changes including aggression, and a shift in focus from the child's best interests to the conflict itself. Though conflicts may remain at one level, those which escalated tended to move sequentially from one level to the next. Understanding how conflicts escalate provides clinicians with a practical, evidence-based framework to identify the warning signs of conflict in paediatrics.

    Given the high levels of obesity among U.S. children, we examine whether obesity in childhood is a passing phenomenon or remains entrenched into adolescence. Data are from the prospective nationally representative Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999 (analytic sample = 6600). Anthropometrics were measured six times during 1998-2007. Overweight and obesity were defined using CDC cut-points. Entrenched obesity was defined as obesity between ages 5-9 coupled with persistent obesity at ages 11 and 14. Almost 30% of children experienced obesity at some point between ages 5.6 and 14.1 years; 63% of children who ever had obesity between ages 5.6 and 9.1 and 72% of those who had obesity at kindergarten entry experienced entrenched obesity. Children with severe obesity in kindergarten or who had obesity at more than 1 year during early elementary were very likely to experience obesity through age 14, regardless of their sex, race, or socioeconomic backgrounds. Prevention should focus on early childhood, as obesity at school entry is not often a passing phenomenon. Even one timepoint of obesity measured during the early elementary school years may be an indicator of risk for long-term obesity. Copyright © 2017 Elsevier Inc. All rights reserved.

  12. Flex-prints for the Mu3e experiment

    Energy Technology Data Exchange (ETDEWEB)

    Dittmeier, Sebastian [Physikalisches Institut, Universitaet Heidelberg (Germany); Collaboration: Mu3e-Collaboration

    2016-07-01

    Mu3e is a novel experiment dedicated to the search for the charged lepton flavor violating decay μ{sup +} → e{sup +}e{sup -}e{sup +} with a targeted sensitivity of a branching ratio (BR) down to 10{sup -16}. Within the standard model of particle physics this process is extremely suppressed to BR<10{sup -54}. Thus, any observation would be a clear sign for new physics beyond the standard model. The Mu3e detector consists of a silicon pixel tracking detector using the novel HV-MAPS (High Voltage Monolithic Active Pixel Sensor) technology to measure the momentum of the decay products, and scintillating fibres and tiles for precise timing. The pixel sensors are thinned to 50 μ m to achieve a material budget of about 0.1% radiation length per tracking layer. The pixel sensors are powered and connected to readout frontend boards using custom designed flex-prints, which are low material interconnects with a high signal density. We present studies of high speed data transmission up to 3.2 Gb/s over flex-print prototypes produced in-house. The design of the flex-prints for the Mu3e detector will be discussed. A 3-layer design including power, ground and slow control distribution, as well as 9 1.25 Gb/s data transmission lines for the readout of the pixel sensors is foreseen.

    The angular analysis of the rare baryon decay of $\\Lambda_{b}\\rightarrow \\Lambda (\\rightarrow p\\pi^{-})\\mu^{+}\\mu^{-}$ in high $q^{2}$ is presented. The dataset that is used corresponds to an integrated luminosity of 5.0 fb$^{-1}$ of pp - collision data collected at centre-of-mass energies between 7 and 13 TeV by the LHCb detector in 2011, 2012, 2015 and 2016. Angular observables are determined using a moment analysis of the angular distribution.

    A search for the decay Bs -> mu+mu- has been performed using proton-proton collisions recorded with the ATLAS detector at the LHC. The Standard Model predicts the time-integrated branching fraction for the decay to be extremely small. CLs tests method is used in extracting upper limit of the branching fraction from the experimental data. This report describes the two test methods used, the counting method and the mass fit method, and compares them.

    A broad peaking structure is observed in the dimuon spectrum of $B^+ \\to K^+ \\mu^+\\mu^-$ decays in the kinematic region where the kaon has a low recoil against the dimuon system. The structure is consistent with interference between the $B^+ \\to K^+ \\mu^+\\mu^-$ decay and a resonance and has a statistical significance exceeding six standard deviations. The mean and width of the resonance are measured to be $4191^{+9}_{-8}\\mathrm{\\,Me\\kern -0.1em V/}c^2$ and $65^{+22}_{-16}\\mathrm{\\,Me\\kern -0.1em V/}c^2$, respectively, where the uncertainties include statistical and systematic contributions. These measurements are compatible with the properties of the $\\psi(4160)$ meson. First observations of both the decay $B^+ \\to \\psi(4160) K^+$ and the subsequent decay $\\psi(4160) \\to \\mu^+\\mu^-$ are reported. The resonant decay and the interference contribution make up 20% of the yield for dimuon masses above 3770  MeV/c2. This contribution is larger than theoretical estimates.

    A search for the decay $B_{s}^0 \\rightarrow \\overline{K}{}^{*0}\\mu^+\\mu^-$ is presented using data sets corresponding to 1.0, 2.0 and 1.6 $\\text{fb}^{-1}$ of integrated luminosity collected during $pp$ collisions with the LHCb experiment at centre-of-mass energies of 7, 8 and 13 TeV, respectively. An excess is found over the background-only hypothesis with a significance of 3.4 standard deviations. The branching fraction of the $B_{s}^0 \\rightarrow \\overline{K}{}^{*0}\\mu^+\\mu^-$ decay is determined to be $\\mathcal{B}(B_{s}^0 \\rightarrow \\overline{K}{}^{*0}\\mu^+\\mu^-) = [2.9 \\pm 1.0~(\\text{stat}) \\pm 0.2~(\\text{syst}) \\pm 0.3~(\\text{norm})] \\times 10^{-8}$, where the first and second uncertainties are statistical and systematic, respectively. The third uncertainty is due to limited knowledge of external parameters used to normalise the branching fraction measurement.

    Perinatal junk food exposure increases the preference for palatable diets in juvenile and adult rat offspring. Previous studies have implicated reduced sensitivity of the opioid pathway in the programming of food preferences; however it is not known when during development these changes in opioid signalling first emerge. This study aimed to determine the impact of a maternal junk food (JF) diet on mu-opioid receptor (MuR) expression and ligand binding in two key regions of the reward pathway, the nucleus accumbens (NAc) and the ventral tegmental area (VTA) in rats during the early suckling (postnatal day (PND) 1 and 7) and late suckling/early post-weaning (PND 21 and 28) periods. Female rats were fed either a JF or a control diet for two weeks prior to mating and throughout pregnancy and lactation. MuR expression in the VTA was significantly reduced in female JF offspring on PND 21 and 28 (by 32% and 57% respectively, Pjunk food exposure on MuR mRNA expression or binding were detected at these time points in male offspring. These findings provide evidence that the opioid signalling system is a target of developmental programming by the end of the third postnatal week in females, but not in males.

    Christ and Lee suggested CP non-invariance as an explanation of the low experimental K/sub L/ to mu /sup +/ mu /sup -/ decay rate. The authors discuss Hamiltonian realizations of this mechanism, and the lower bounds on the K/sub S/ to mu /sup +/ mu /sup -/ decay rate implied by them. The lower bound on the K/sub S/ to mu /sup +/ mu /sup -/ branching ratio varies in these models from 10 * 10/sup -7/ (for the most economical model) to 2 * 10/sup -7/. (20 refs).

    The aim of this research is to initiate a 5-year natural history study of dry eye disease (DED) using objectively assessed and patient-reported outcomes, to explore the hypothesis that DED is a progressive condition that has substantive and measurable impacts not only on the ocular surface, but on quality of life and visual functioning. Our objective for this report is to examine the baseline data. A multicenter, prospective, controlled, observational study of Level 2 (mild-to-moderate) DED patients based on International Task Force Delphi Panel severity grading, and controls, documented baseline measures (including tear film biomarkers and quality of life). Tear cytokine concentrations were also measured in the tear film. Patients were using artificial tears as needed. Two hundred seventeen DED patients and 67 gender- and age-matched controls were enrolled. A majority were females and Caucasian and groups did not differ significantly in terms of gender, race, or age. Differences between DED and matched controls, at baseline, included mean scores for Ocular Surface Disease Index (31.7 vs 4.1, P eye care practitioners in mild to moderate DED patients compared to normal subjects of similar ages and genders.

    The Mu2e experiment searches for the neutrinoless muon to electron conversion in the field of a nucleus, which is a charged lepton flavor violating process. The goal of the experiment is to reach a single event sensitivity of 2.8×10"−"1"7, setting an upper limit on the muon conversion rate of 6.7 × 10"−"1"7. This corresponds to a four order of magnitude improvement with respect to the existing limits.

    Mu promoters active during the lytic cycle were located by isolating RNA at various times after induction of Mu prophages, radiolabeling it by capping in vitro, and hybridizing it to Mu DNA fragments on Southern blots. Signals were detected from four new promoters in addition to the previously characterized P e (early), P cM (repressor), and P mom (late) promoters. A major signal upstream of C was first observed at 12 min and intensified thereafter with RNA from cts and C amber but not replication-defective prophages; these characteristics indicate that this signal arises from a middle promoter, which we designate P m . With 20- and 40-min RNA, four additional major signals originated in the C-lys, F-G-I, N-P, and com-mom regions. These signals were missing with RNA from C amber and replication-defective prophages and therefore reflected the activity of late promoters, one of which we presume was P mom . Uninduced lysogens showed weak signals from five regions, one from the early regulatory region, three between genes B and lys, and one near the late genes K, L, and M. The first of these probably resulted from P cM activity; the others remain to be identified

    The search for new physics is the current aim of particle physics and might be pursued $\\textit{directly}$, by producing new possible particles in high energy collisions, or $\\textit{indirectly}$, by measurements of processes in which loops of new virtual particles might affect, for example, the decay rate. Being not limited by the collision energy, indirect searches are sensitive to particle masses which are larger than those accessible in direct searches. For this reason, indirect searches are a powerful tool to probe heavy particles that cannot be produced at colliders. The $B^0_{d,s}\\to\\mu^+\\mu^-$ decays are among the most sensitive probes to physics beyond the Standard Model. Such decays are extremely rare, occurring few times in billions of $B$ decays, due to loop and helicity suppressions. The decay probability is however precisely predicted in the Standard Model, as the purely leptonic final state allows to condensate hadronic interactions into a single constant. The search for $B^0_{d,s}\\to\\mu^+\\m...

    A search for the decays B{sub s}{sup 0}{yields}{mu}{sup +}{mu}{sup -} and B{sup 0}{yields}{mu}{sup +}{mu}{sup -} is performed with 0.37 fb{sup -1} of pp collisions at {radical}(s)=7 TeV collected by the LHCb experiment in 2011. The upper limits on the branching fractions are B(B{sub s}{sup 0}{yields}{mu}{sup +}{mu}{sup -})<1.6 Multiplication-Sign 10{sup -8} and B(B{sup 0}{yields}{mu}{sup +}{mu}{sup -})<3.6 Multiplication-Sign 10{sup -9} at 95% confidence level. A combination of these results with the LHCb limits obtained with the 2010 dataset leads to B(B{sub s}{sup 0}{yields}{mu}{sup +}{mu}{sup -})<1.4 Multiplication-Sign 10{sup -8} and B(B{sup 0}{yields}{mu}{sup +}{mu}{sup -})<3.2 Multiplication-Sign 10{sup -9} at 95% confidence level.

    There is evidence of genetic and neural system overlap in Autism Spectrum Disorder (ASD) and Early Psychosis (EP). Five datasets were pooled to compare mu suppression index (MSI), a proxy of mirror neuron activity, in EP, high functioning ASD, and healthy subjects (HS). ASDs and EPs with "active" negative symptoms showed significant differences in mu suppression, in response to Biological Motion/point-light display animation, compared to HS. Preliminary findings suggest that similar neural network deficits in ASD and EP could be driven by the expression of negative symptoms in the latter group of patients. These findings may aid future studies on EP and ASD and facilitate the formulation of new hypotheses regarding their pathophysiology. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Psychometric, anatomical and functional brain studies suggest that individuals differ in the way that they perceive and analyze information and strategically control and execute movements. Inter-individual differences are also observed in neural correlates of specific and general cognitive ability. As a result, some individuals perceive and adapt to environmental conditions and perform motor activities better than others. The aim of this study was to identify a common factor that predicts adaptation of a reaching movement to a visual perturbation and suppression of movement-related brain activity (mu rhythms). Twenty-eight participants participated in two different experiments designed to evaluate visuomotor adaptation and mu suppression ability. Performance intelligence quotient (IQ) was assessed using the revised Wechsler Adult Intelligence Scale. Performance IQ predicted adaptation index of visuomotor performance (r=0.43, p=0.02) and suppression of mu rhythms (r=-0.59; pIQ were faster at adapting to a visuomotor perturbation and better at suppressing mu activity than participants with low performance IQ. We found a possible link between performance IQ and mu suppression, and performance IQ and the initial rate of adaptation. Individuals with high performance IQ were better in suppressing mu rhythms and were quicker at associating motor command and required movement than individuals with low performance IQ.

    Muscle specific tyrosine kinase myasthenia gravis (MuSK MG) is a form of autoimmune MG that predominantly affects women and has unique clinical features, including prominent bulbar weakness, muscle atrophy, and excellent response to therapeutic plasma exchange. Patients with MuSK MG have predominantly IgG4 autoantibodies directed against MuSK on the postsynaptic muscle membrane. Lymphocyte functionality has not been reported in this condition. The goal of this study was to characterize T-cell responses in patients with MuSK MG. Intracellular production of IFN-gamma, TNF-alpha, IL-2, IL-17, and IL-21 by CD4+ and CD8+ T-cells was measured by polychromatic flow cytometry in peripheral blood samples from 11 Musk MG patients and 10 healthy controls. Only one MuSK MG patient was not receiving immunosuppressive therapy. Regulatory T-cells (Treg) were also included in our analysis to determine if changes in T cell function were due to altered Treg frequencies. CD8+ T-cells from MuSK MG patients had higher frequencies of polyfunctional responses than controls, and CD4+ T-cells had higher IL-2, TNF-alpha, and IL-17. MuSK MG patients had a higher percentage of CD4+ T-cells producing combinations of IFN-gamma/IL-2/TNF-gamma, TNF-alpha/IL-2, and IFN-gamma/TNF-alpha. Interestingly, Treg numbers and CD39 expression were not different from control values. MuSK MG patients had increased frequencies of Th1 and Th17 cytokines and were primed for polyfunctional proinflammatory responses that cannot be explained by a defect in Treg function or number.

    Muon dynamics and forced chemical confinement fusion in three-layer arrangement consisting of the H/T, D{sub 2} (the degrader and moderator) and D/T fusion layers are investigated with a new kinetic model. Point kinematic equations are numerically solved to calculate the numbers of dt{mu}, tt{mu} and dd{mu} chain reactions. We show that the {mu}-cycling coefficient X{sub c} approximately equals 156, at optimal condition. Our model and results are in contradiction with beliefs of Mahdavi and Zanganeh. Our model is confirmed by recent experiment where was performed for the hydrogen mixture. (author)

    The vinegar fly Drosophila melanogaster is used as model organism to study a variety of different scientific purposes. Thus, our laboratory studies the olfactory system by neurobiological experiments. These techniques are often disruptive and need to compensate or exchange the body fluid, the lymph, with an artificial Ringer's solution in defined compartments of the fly. The solution mainly contains Na, Cl, K and Ca and is to keep physiological conditions. Therefore, the knowledge about the ion concentrations in the respective Drosophila lymph is required for a correct mixture of the ions. This paper presents the spatially resolved concentrations of P, S, Cl, K, Ca, Fe, Cu and Zn in lyophilised head cryosections of Drosophila by using quantitative {mu}PIXE at the ion beam facility LIPSION in Leipzig. The PIXE maps enable a detailed analysis of particular regions of interest down to a spatial resolution of 0.5 {mu}m. We quantified the ion concentrations especially in the brain, the antenna and its sensilla hairs acting as the olfactory organ of the fly, in the compound eye and in the mouthparts. The averaged element concentrations of these main compartments are (in descending order): P: 90 mM, K: 81 mM, S: 38 mM, Cl: 18 mM, Ca: 4.9 mM, Fe: 1.4 mM, Zn: 1.2 mM, Cu: 0.06 mM. Certain structures or cavities possess a remarkably high concentration of particular elements and might reflect the different functions of the compartments. An example presented in more detail is the composition of the compound eye. Conclusively, our findings on the ion concentrations might be useful for the mixture of the Drosophila Ringer's solution to ensure physiological conditions in experiments.

    This note presents a study of the prospects for the measurement of the rare Higgs boson decay $H\\to \\mu\\mu$ using 3000 fb$^{-1}$ of proton-proton collisions at $\\sqrt{s}=14$ TeV recorded with the ATLAS detector at the high-luminosity LHC. The studies assume an average number of interactions per bunch crossing $\\langle\\mu\\rangle=200$. The $H\\to\\mu\\mu$ signal from gluon fusion and vector-boson fusion is expected to be observed with a significance of more than 9 standard deviations. The uncertainty on the Higgs production cross section times the branching ratio to dimuons normalised by the Standard Model prediction is expected to be around 13%.

    MuLan and MuCap are ongoing experiments at the Paul Scherrer Institut, Switzerland, that use the muon lifetime to determine fundamental weak interaction parameters. The goal of MuLan is a 1 ppm measurement of the positive muon lifetime τ μ + to determine the Fermi constant G F to 0.5 ppm. The goal of MuCap is to make a 1% determination of the rate Λ S of the process of nuclear muon capture by the proton, μp→nν, by measuring the μ - disappearance rate in hydrogen gas to 10 ppm and subtracting the world average for the μ + decay rate. A 1% determination of the capture rate Λ S is of interest because it would enable a 7% determination of g P , the induced pseudoscalar coupling of the nucleon. In 2007, both experiments published first results based upon data collected by each in 2004. MuLan reported an 11 ppm μ + lifetime measurement, τ μ + = 2.197 013(24) μs, resulting in a new, 9.6 ppm world average, τ μ + = 2.197 019(21) μs, which determines the Fermi constant, G F = 1.166 371(6)x10 -5 GeV -2 , to 5 ppm. MuCap reported a 3% measurement of the muon capture rate from the hyperfine singlet ground state of the μp atom, Λ S = 725.0±17.4 s -1 , from which a 15% value for the pseudoscalar coupling, g P (q 2 = -0.88m μ 2 ) = 7.3±1.1, was extracted

    The Mu2e experiment at Fermilab is in the midst of its R&D and approval processes. To aid and inform this process, a small team has developed an end-to-end Geant4-based simulation package and has developed reconstruction code that is already at the stage of an advanced prototype. Having these tools available at an early stage allows design options and tradeoffs to be studied using high level physics quantities. A key to the success of this effort has been, as much as possible, to acquire software and customize it, rather than to build it in-house.

    Psychologically, females are usually thought to be superior in interpersonal sensitivity than males. The human mirror-neuron system is considered to provide the basic mechanism for social cognition. However, whether the human mirror-neuron system exhibits gender differences is not yet clear. We measured the electroencephalographic mu rhythm, as a reliable indicator of the human mirror-neuron system activity, when female (N = 20) and male (N = 20) participants watched either hand actions or a moving dot. The display of the hand actions included androgynous, male, and female characteristics. The results demonstrate that females displayed significantly stronger mu suppression than males when watching hand actions. Instead, mu suppression was similar across genders when participants observed the moving dot and between the perceived sex differences (same-sex vs. opposite-sex). In addition, the mu suppressions during the observation of hand actions positively correlated with the personal distress subscale of the interpersonal reactivity index and negatively correlated with the systemizing quotient. The present findings indirectly lend support to the extreme male brain theory put forward by Baron-Cohen (2005), and may cast some light on the mirror-neuron dysfunction in autism spectrum disorders. The mu rhythm in the human mirror-neuron system can be a potential biomarker of empathic mimicry.

    An angular analysis of the decay $B^0_d \\to K^{*}\\mu^+\\mu^-$ is presented, based on proton-proton collision data recorded by the ATLAS experiment at the LHC. The study is using 20.3 fb$^{-1}$ of integrated luminosity collected during 2012 at centre-of-mass energy of $\\sqrt{s}=8$ TeV. Measurements of the $K^{*}$ longitudinal polarisation fraction and a set of angular parameters obtained for this decay are presented. The results are compatible with the Standard Model predictions.

    We present searches for the rare decay modes D{sup 0} {yields} e{sup +}e{sup -}, D{sup 0} {yields} {mu}{sup +}{mu}{sup -}, and D{sup 0} {yields} e{sup {+-}}{mu}{sup {-+}} in continuum e{sup +}e{sup -} {yields} c{bar c} events recorded by the BABAR detector in a data sample that corresponds to an integrated luminosity of 468 fb{sup -1}. These decays are highly GIM suppressed but may be enhanced in several extensions of the Standard Model. Our observed event yields are consistent with the expected backgrounds. An excess is seen in the D{sup 0} {yields} {mu}{sup +}{mu}{sup -} channel, although the observed yield is consistent with an upward background fluctuation at the 5% level. Using the Feldman-Cousins method, we set the following 90% confidence level intervals on the branching fractions: {Beta}(D{sup 0} {yields} e{sup +}e{sup -}) < 1.7 x 10{sup -7}, {Beta}(D{sup 0} {yields} {mu}{sup +}{mu}{sup -}) within [0.6, 8.1] x 10{sup -7}, and {Beta}(D{sup 0} {yields} e{sup {+-}}{mu}{sup {-+}}) < 3.3 x 10{sup -7}.

    Everett, Christopher; Blake, Thomas

    This work presents an angular analysis of the suppressed $\\Lambda_b^0 \\rightarrow \\Lambda\\mu^+\\mu^-$ decay, performed using proton-proton collision data collected by the LHCb experiment during 2011 and 2012. The distribution of moments describing the decay with a non-zero transverse $\\Lambda_b^0$ baryon polarisation production are extracted for the first time, and used to determine the 5-dimensional angular distribution in the 15 to 20 GeV$^2/c^4$ dimuon invariant mass squared interval for the first time. The forward-backward asymmetry of the $\\Lambda$ baryon and $\\mu^+\\mu^-$ produced from the $\\Lambda_b^0$ baryon ($A_{FB}^{lh}$ ) is measured, along with the previously published $f_L$, $A^l_{FB}$ and $A^h_{FB}$. These values are found to be $f_L = 0.546 \\pm 0.132$, $A^l_{FB} = -0.004 \\pm 0.077$, $A^h_{FB} = -0.312 \\pm 0.150$ and $A_{FB}^{lh} = -0.007 ± 0.071$, where uncertainties are statistical, and account for correlation between the moments used to determine them.

    A search is presented for hidden-sector bosons, $\\chi$, produced in the decay ${B^0\\!\\to K^*(892)^0\\chi}$, with $K^*(892)^0\\!\\to K^{+}\\pi^{-}$ and $\\chi\\!\\to\\mu^+\\mu^-$. The search is performed using $pp$-collision data corresponding to 3.0 fb$^{-1}$ collected with the LHCb detector. No significant signal is observed in the accessible mass range $214 \\leq m({\\chi}) \\leq 4350$ MeV, and upper limits are placed on the branching fraction product $\\mathcal{B}(B^0\\!\\to K^*(892)^0\\chi)\\times\\mathcal{B}(\\chi\\!\\to\\mu^+\\mu^-)$ as a function of the mass and lifetime of the $\\chi$ boson. These limits are of the order of $10^{-9}$ for $\\chi$ lifetimes less than 100 ps over most of the $m(\\chi)$ range, and place the most stringent constraints to date on many theories that predict the existence of additional low-mass bosons.

  2. Charm and beauty production in D{sup *}{mu} events at H1/HERA

    Charm and beauty photoproduction is investigated with the H1 detector at HERA using events with a reconstructed D{sup *} meson and a muon. Data taken during the years 1999-2000 and 2004-2006, corresponding to a total integrated luminosity of 320 pb{sup -1}, are analysed. The D{sup *} mesons with transverse momentum p{sub t}(D{sup *})>1.5 GeV and pseudorapidity vertical stroke {eta}(D{sup *}) vertical stroke <1.5 are reconstructed via the decay channel D{sup *{+-}}{yields}D{sup (-)0}{pi}{sub s}{sup {+-}}{yields}(K{sup -+}{pi}{sup {+-}}){pi}{sub s}{sup {+-}}. In addition, muons with momentum p({mu})>2 GeV and vertical stroke {eta}({mu}) vertical stroke <1.735 are selected. With this selection, the contribution of light quark initiated events is negligible. The fractions of charm and beauty events in data are extracted exploiting the charge and azimuthal angle correlation between the D{sup *} meson and the muon. The charm and beauty cross sections were measured in photoproduction, i.e. for photon virtualities Q{sup 2}<1 GeV{sup 2}, and for inelasticities 0.05mu}X)=314{+-}33(stat){+-}101(syst)pb {sigma}{sub vis}(ep{yields}eb anti bX{yields}eD{sup *{+-}}{mu}X)=90{+-}20(stat){+-}26(syst)pb. The measurements are compared to leading order QCD calculations supplemented with parton showers as predicted by the PYTHIA Monte Carlo event generator. A ratio data/theory of 1.2{+-}0.1(stat){+-}0.4(syst) and of 1.3{+-}0.3(stat){+-}0.4(syst) is obtained for charm and beauty, respectively. Differential cross sections for the variables describing the D{sup *}{mu} system like transverse momentum p{sub t}(D{sup *}{mu}), pseudorapidity {eta}(D{sup *}{mu}), invariant mass M(D{sup *}{mu}) and inelasticity y(D{sup *}{mu}) are measured and compared to the PYTHIA and the CASCADE Monte Carlo event generators. The theoretical models describe the shape of the differential distributions. Transverse momentum studies of the D

    Full Text Available It is common for users to relocate information previously found on the web. However, their search behaviors in initial finding and the subsequent re-finding may differ due to the dynamic nature and contextual diversity of the web. This study used experiment, observation, interview, and questionnaires to investigate the characteristics of re-finding behavior and compare users’ performance in finding and re-finding. Though not significantly different, the study participants used more search tools, combined various strategies to obtain contextual clues of finding process, utilized more complex search tactics, and had more interactions with search engines used. Findings also show that participants spent less time in re-finding than in finding, yet the cognitive loading and difficulties increased in re-finding. Participants were satisfied with the results obtained in re-finding, but they also claimed that the search performance would be better if the system offered more functions to support recall of previous search results. Participants’ satisfaction with search performance also varied by task type. Based on the findings, this study recommends that re-finding efficiency may be improved by enhancing recall functionalities in browsers and by using personal information management tools.

    Full Text Available Anxiolytic drugs are widely used in the elderly, a population particularly sensitive to stress. Stress, aging and anxiolytics all affect low-frequency oscillations in the hippocampus and prefrontal cortex (PFC independently, but the interactions between these factors remain unclear. Here, we compared the effects of stress (elevated platform, EP and anxiolytics (diazepam, DZP on extracellular field potentials (EFP in the PFC, parietal cortex and hippocampus (dorsal and ventral parts of adult (8 months and aged (18 months Wistar rats. A potential source of confusion in the experimental studies in rodents comes from locomotion-related theta (6–12 Hz oscillations, which may overshadow the direct effects of anxiety on low-frequency and especially on the high-amplitude oscillations in the Mu range (7–12 Hz, related to arousal. Animals were restrained to avoid any confound and isolate the direct effects of stress from theta oscillations related to stress-induced locomotion. We identified transient, high-amplitude oscillations in the 7–12 Hz range (“Mu-bursts” in the PFC, parietal cortex and only in the dorsal part of hippocampus. At rest, aged rats displayed more Mu-bursts than adults. Stress acted differently on Mu-bursts depending on age: it increases vs. decreases burst, in adult and aged animals, respectively. In contrast DZP (1 mg/kg acted the same way in stressed adult and age animal: it decreased the occurrence of Mu-bursts, as well as their co-occurrence. This is consistent with DZP acting as a positive allosteric modulator of GABAA receptors, which globally potentiates inhibition and has anxiolytic effects. Overall, the effect of benzodiazepines on stressed animals was to restore Mu burst activity in adults but to strongly diminish them in aged rats. This work suggests Mu-bursts as a neural marker to study the impact of stress and DZP on age.

  7. Towards the first $B(B^{0}_{(s)} \\to \\mu^+\\mu^−)$ measurements with the LHCb detector

    CERN Document Server

    Adrover Pacheco, Cosme; Le Gac, Renaud

    The rare decays $B^{0}_{s} \\to \\mu^+ \\mu^-$ and $B^{0} \\to \\mu^+ \\mu^-$ are benchmark channels to constrain models beyond the Standard Model (BSM) with a larger Higgs sector. In the SM, the branching fraction of these decays is predicted with a good accuracy: $\\mathcal{B}(B^{0}_{(s)} \\to \\mu^+ \\mu^-) = (3.2 \\pm 0.2) \\times 10^{-9}$ and $\\mathcal{B}(B^{0} \\to \\mu^+ \\mu^-) = (0.10 \\pm 0.01) \\times 10^{-10}$. Any deviation from these values can lead to indications of physics BSM. The core of this thesis comprises two main topics: the background rejection and the signal yields extraction. We have optimized a multivariate classifier based on the boosted decision trees technique allowing for a drastic reduction of the $B \\to h^+ h'^-$ ($h \\equiv \\pi, K$) background. After the selection process, about 76$\\%$ of the combinatorial background for $B^{0}_{s} \\to \\mu^+ \\mu^-$ is removed, while keeping a signal efficiency of about 92$\\%$. A further discrimination between signal and background is accomplished with anoth...

    2018-04-26

    We discuss injection of 800 MeV proton beam from PIP-II into the production target for Mu2e-II, assuming a targeting and μ production scenario similar to mu2e. The incoming beam trajectory must be modified from the mu2e parameters to match the focusing fields. Adding a vertical deflection at injection enables the injected beam to reach the target. Other differences from the mu2e system must be considered, including changes in the target structure, the radiation shielding and beam dump/absorber. H- beam should be stripped to p+. Other variations are discussed.

    The Mu2e experiment at FNAL aims to measure the charged-lepton flavor violating neutrinoless conversion of a negative muon into an electron. The conversion results in a monochromatic electron with an energy slightly below the muon rest mass (104.97 MeV). The calorimeter should confirm that the candidates reconstructed by the extremely precise tracker system are indeed conversion electrons while performing a powerful μ/e particle identification. Moreover, it should also provide a high level trigger for the experiment independently from the tracker system. The calorimeter should also be able to keep functionality in an environment where the background delivers a dose of ∼ 10 krad/year in the hottest area and to work in the presence of 1 T axial magnetic field. These requirements translate in the design of a calorimeter with large acceptance, good energy resolution O(5%) and a reasonable position (time) resolution of ∼ < 1 cm (<0.5ns). The baseline version of the calorimeter is composed by two disks of inner (outer) radius of 351 (660) mm filled by 1860 hexagonal BaF 2 crystals of 20 cm length. Each crystal is readout by two large area APD's. In this paper, we summarize the experimental tests done so far as well as the simulation studies in the Mu2e environment

    This summary presents some of the findings from the 226 Ra and 239 Pu lifespan carcinogenesis studies in Beagle dogs and discusses these findings relative to the tissue, cellular and molecular biology of osseous tissues. This report attempts to integrate some of the dosimetric and pathological findings with current understanding of the factors that may influence carcinogenesis (and non-carcinogenic pathologies) at the various levels of biological organization. Emphasis is placed on the findings from the 226 Ra study, as this study has recently been completely reviewed and verified

  13. Characterisation of the Novel Mixed Mu-NOP Peptide Ligand Dermorphin-N/OFQ (DeNo.

    Mark F Bird

    Full Text Available Opioid receptors are currently classified as Mu (μ, Delta (δ, Kappa (κ plus the opioid related nociceptin/orphanin FQ (N/OFQ peptide receptor (NOP. Despite compelling evidence for interactions and benefits of targeting more than one receptor type in producing analgesia, clinical ligands are Mu agonists. In this study we have designed a Mu-NOP agonist named DeNo. The Mu agonist component is provided by dermorphin, a peptide isolated from the skin of Phyllomedusa frogs and the NOP component by the endogenous agonist N/OFQ.We have assessed receptor binding profile of DeNo and compared with dermorphin and N/OFQ. In a series of functional screens we have assessed the ability to (i increase Ca2+ in cells coexpressing recombinant receptors and a the chimeric protein Gαqi5, (ii stimulate the binding of GTPγ[35S], (iii inhibit cAMP formation, (iv activate MAPKinase, (v stimulate receptor-G protein and arrestin interaction using BRET, (vi electrically stimulated guinea pig ileum (gpI assay and (vii ability to produce analgesia via the intrathecal route in rats.DeNo bound to Mu (pKi; 9.55 and NOP (pKi; 10.22 and with reasonable selectivity. This translated to increased Ca2+ in Gαqi5 expressing cells (pEC50 Mu 7.17; NOP 9.69, increased binding of GTPγ[35S] (pEC50 Mu 7.70; NOP 9.50 and receptor-G protein interaction in BRET (pEC50 Mu 8.01; NOP 9.02. cAMP formation was inhibited and arrestin was activated (pEC50 Mu 6.36; NOP 8.19. For MAPK DeNo activated p38 and ERK1/2 at Mu but only ERK1/2 at NOP. In the gpI DeNO inhibited electrically-evoked contractions (pEC50 8.63 that was sensitive to both Mu and NOP antagonists. DeNo was antinociceptive in rats.Collectively these data validate the strategy used to create a novel bivalent Mu-NOP peptide agonist by combining dermorphin (Mu and N/OFQ (NOP. This molecule behaves essentially as the parent compounds in vitro. In the antonocicoeptive assays employed in this study DeNo displays only weak antinociceptive

    55 out of 62 patients with cerebral infarction were investigated in terms of CT scan findings, angiographic findings, and clinical symptoms. The results obtained were as follows: 1) The low-density areas of the CT scan findings were classified into the following four types: large hemispheric or lobular --Type I; wedge-shaped --Type II; small --Type III; and lacunar low-density area. --Type IV. 2) Almost all patients with angiographically occlusive findings showed low-density areas of Type I; however, one patient with ICA occlusion revealed only a lacunar low-density area. 3) The patients with lacunar low-density areas showed an angiographically delayed filling of the angular artery and posterior parietal artery of the middle cerebral artery. 4) The relationship between the types of low-density areas and the clinical conscious disorders was not clear. On the other hand, the patients with Type I low-density areas almost all had motor disturbances, while patients with other types of low-density areas showed only 60 - 70% motor disturbances. 5) In patients with speech disorders, total aphasia cases were found in patients with large hemispheric low-density areas on the left side. Although, motor aphasia cases were seen in patients with various low-density areas on the left inferior frontal and precentral gyri, dysarthria cases were found in the patients with several low-density areas on both sides. 6) The localization of lacunar low-density areas seemed to be near the caudate nucleus on the right side and in the putaminal regions on the left side. The mean and the standard deviation of CT numbers in the lacunar low-density areas showed higher values on the right side than on the left side. (author)

    The world largest proton-proton collider, the Large Hadron Collider (LHC), which was built up at CERN in the near of Geneva, will start its operation in summer 2009. The total τ lepton production cross-section for the CMS experiment, at a center-of-mass energy of 14 TeV, is about 140 μb. Assuming an integrated luminosity of 10 fb−1 per year, which is expected to be reached in the low luminosity phase of L = 2 × 1033 cm−2 s−1 , about 1012 τ leptons are produced in total. This copious τ production at the LHC provides an excellent potential for the search of neutrinoless and therefore lepton flavour violating τ decays. It is already known since the experimental discovery of neutrino oscillations, that the conservation law of the lepton family number is not strict. The neutrino oscillations have dramatic consequences for the picture of leptons in the Standard Model. The neutrinos become massive particles, the mass eigenstates differ from the flavour eigenstates and a mixing matrix similar to the CKM m...

    The observation of the $\\mathrm{Z}$ boson rare decay to a $\\psi$ meson and two oppositely charged same-flavour leptons, $\\ell^+ \\ell^-$, where $\\psi$ represents the sum of $\\mathrm{J}/\\psi$ and $\\psi(\\mathrm{2S})\\to\\mathrm{J}/\\psi\\, X$, and $\\ell=\\mu,\\mathrm{e}$, is presented. The data sample used corresponds to an integrated luminosity of $35.9\\,\\mathrm{fb}^{-1}$ of proton-proton collisions at a center-of-mass energy of $13\\,\\mathrm{TeV}$ accumulated by the CMS experiment at the LHC. The signal is observed with a significance in excess of 5 standard deviations. Removing contributions from $\\psi(\\mathrm{2S})$ decays to $\\mathrm{J}/\\psi$, the signal is interpreted as being entirely from $\\mathrm{Z}\\to\\mathrm{J}/\\psi\\,\\ell^+\\ell^-$, with its fiducial branching fraction relative to that of the decay $\\mathrm{Z}\\to\\mu^+\\mu^-\\mu^+\\mu^-$ measured to be $$\\frac{\\mathcal{B}(\\mathrm{Z}\\to\\mathrm{J}/\\psi\\,\\ell^+\\ell^-)}{\\mathcal{B}(\\mathrm{Z}\\to\\mu^+\\mu^-\\mu^+\\mu^-)}=0.70\\pm 0.18\\, \\mathrm{(stat)} \\pm 0.05\\, \\mathrm{(s...

    LHCb is one of the four main experiments hosted at the Large Hadron Collider (LHC) at CERN. The LHC first started in September 2008 and, after a one-year hiccough, restarted in November 2009. In the course of three weeks, the HEP community witnessed the first LHC proton-proton collisions and a new record of the most energetic particle beam. The ease shown by the operators of the complex LHC machine augurs very well for the extended period of data-taking scheduled to start at the end of February 2010. LHCb is the LHC experiment primarily dedicated to the $b$ realm, through the study of $\\mathcal{CP}$ violation and rare decays. Its physics goals are ambitious: it aims at the indirect search of New Physics and at the precise measurements of $\\mathcal{CP}$ violation parameters. The LHCb detector was designed as a single-arm forward spectrometer. The branching fraction of the yet-unobserved $B^{0}_{s}\\to\\mu^{+}\\mu^{-}$ decay is currently considered as one of the most stringent tests for the existence of physics be...

  20. Use of $B \\to h^+ h^{'-}$ as control channels for the measurement of BR$(B^0_s \\to \\mu^+ \\mu^-)$ at LHC$b$

    In spite of the impressive success of the Standard Model, some theoretical and experimental facts suggest that it might not be the $final$ theory, and hence that $new$ $physics$ exists. Decays of $B$ meson are an exceptional source of observables where physics beyond the SM could lead to unambiguous effects. Indeed, measurements in this sector provide some of the first possibilities of observing effects from new physics at the LHC. This is the case of the branching ratio of the yet unobserved decay $B^0_s \\to \\mu^+ \\mu^-$. This observable is precisely predicted by the Standard Model and hence it is also very sensitive to new physics. The conception of LHC$b$ as a dedicated experiment for $B$ physics studies puts it is an outstanding position for measuring this branching ratio with respect to other experiments operating at the LHC. The measurement of the branching ratio of $B^0_s \\to \\mu^+ \\mu^-$ at LHC$b$ widely uses methods for both calibrating and normalizing independently of the Monte Carlo simulations, ba...

  1. Usurping the Apocryphal: Antonio Muñoz Molina's Cosmopolitan Memory of Max Aub's Rhetoric of Testimony

    OpenAIRE

    Aguirre Oteiza, Daniel

    2017-01-01

    This paper focuses on a recent gesture by the Spanish novelist and public intellectual Antonio Muñoz Molina to publicly recuperate Aub’s testimony of uprootedness in France, Algeria, and Mexico, a gesture that relies on the concept of cosmopolitan memory as it has been developed in Holocaust studies. I critique Muñoz Molina’s use of the Holocaust as a template for a transnational cultural history based on a supposedly shared Jewish past. Muñoz Molina generalizes on two levels: he turns Aub in...

    A search for the decay K/sub S/ to 2 mu has given negative results. The 90% confidence upper limit for the branching ratio of 3.1*10/sup -7/ excludes the models of Christ and Lee, and of Dass and Wolfenstein, designed to explain the K/sub L/ to 2 mu problem. (8 refs).
