    Title of the article: A Study of structured rehabilitationexercise program in Parkinson’s diseaseContext: There is a growing need to address rehabilitationissues to supplement medical therapy.Aims: To assess the impact of rehabilitation interventionin the functional status and quality of life in patients withParkinson’s disease.Settings and Design: Prospective follow-up study in ateaching hospitalMaterials and Methods: Twenty-eight cases withParkinson’s Disease on a stable pharmacological regimenand moderately disabled participated in this study. Allpatients were given the same set of exercises. Duringthe first month, patients performed exercises undersupervision at the hospital and rest of the days at home.In the second and third month, patients continued thesame exercises at home. During the fourth month, patientsmaintained their usual level of physical activity butdiscontinued the exercises. All patients were evaluatedat 0, 1, 2, 3 and 4 months. Outcome measures used wereUnified Parkinson’s Disease Rating Scale (UPDRS)version 3.0, Webster step seconds product, andParkinson’s Disease Quality of Life Questionnaire(PDQL)Results: Significant improvements were observed inUPDRS section 1 (Mentation, behavior and mood),sections 2 and 6 (Activities of Daily Living), PDQLsubscales (parkinsonian symptoms, systemic symptomsand social functioning), and Webster step-seconds product.Conclusions: Systematic program of physical therapy isbeneficial in patients suffering from moderately disabledParkinson’s disease. Activities of daily living like dressing,turning in bed and walking respond favorably to exercises.Quality of life improves considerably following exercisesleading to increased social participatio

    Femtosecond nonlinear ultrasonics in gold probed with ultrashort surface plasmons

    Fundamental interactions induced by lattice vibrations on ultrafast time scales become increasingly important for modern nanoscience and technology. Experimental access to the physical properties of acoustic phonons in the THz frequency range and over the entire Brillouin zone is crucial for understanding electric and thermal transport in solids and their compounds. Here, we report on the generation and nonlinear propagation of giant (1 percent) acoustic strain pulses in hybrid gold/cobalt bilayer structures probed with ultrafast surface plasmon interferometry. This new technique allows for unambiguous characterization of arbitrary ultrafast acoustic transients. The giant acoustic pulses experience substantial nonlinear reshaping already after a propagation distance of 100 nm in a crystalline gold layer. Excellent agreement with the Korteveg-de Vries model points to future quantitative nonlinear femtosecond THz-ultrasonics at the nano-scale in metals at room temperature

    Observation of chi_c2 Production in B-meson Decay

    Full text link
    We report the first observation of chi_c2 production in B-meson decays. We find an inclusive B -> chi_c2 X branching fraction of (1.80^{+0.23}_{-0.28}+/- 0.26) 10^-3. The data set, collected with the Belle detector at the KEKB e^+e^- collider, consists of 31.9 million B\bar B events. We also present branching fractions and momentum spectra for both chi_c1 and chi_c2 production.Comment: 5 pages with 2 figure

    Measurement of B0d - B0d-bar mixing rate from the time evolution of dilepton events at the Upsilon(4S)

    Full text link
    We report a determination of the B0d - B0d-bar mixing parameter Delta-m_d based on the time evolution of dilepton yields in Upsilon(4S) decays. The measurement is based on a 5.9 /fb data sample collected by the Belle detector at KEKB. The proper-time difference distributions for same-sign and opposite-sign dilepton events are simultaneously fitted to an expression containing Delta-m_d as a free parameter. Using both muons and electrons, we obtain Delta-m_d = 0.463 +- 0.008(stat.) +- 0.016(sys.) ps^{-1} This is the first determination of Delta-m_d from time evolution measurements at the Upsilon(4S). We also place limits on possible CPT violations.Comment: 12 pages, 2 figure

    Combined search for the standard model Higgs boson decaying to a bb pair using the full CDF data set

    Get PDF
    We combine the results of searches for the standard model Higgs boson based on the full CDF Run II data set obtained from sqrt(s) = 1.96 TeV p-pbar collisions at the Fermilab Tevatron corresponding to an integrated luminosity of 9.45/fb. The searches are conducted for Higgs bosons that are produced in association with a W or Z boson, have masses in the range 90-150 GeV/c^2, and decay into bb pairs. An excess of data is present that is inconsistent with the background prediction at the level of 2.5 standard deviations (the most significant local excess is 2.7 standard deviations).Comment: To be published in Phys. Rev. Lett (v2 contains minor updates based on comments from PRL

    Observation of Mixing-induced CP Violation in the Neutral B Meson System

    Full text link
    This report describes an observation of mixing-induced CP violation and a measurement of the CP violation parameter, sin(2phi_1), with the Belle detector at the KEKB asymmetric e+e- collider. Using a data sample of 29.1 fb-1 recorded on the Upsilon(4S) resonance that contains 31.3 million BBbar pairs, we reconstruct decays of neutral B mesons to the following CP eigenstates: J/psi K_S^0, psi(2S) K_S^0, chi_c1 K_S^0, eta_c K_S^0, J/psi K_L^0 and J/psi K^*0. The flavor of the accompanying B meson is identified by combining information from primary and secondary leptons, K+/- mesons, lambda baryons, slow and fast pions. The proper-time interval between the two B meson decays is determined from the distance between the two decay vertices measured with a silicon vertex detector. The result sin(2phi_1) = 0.99 +/- 0.14(stat) +/- 0.06(syst) is obtained by applying a maximum likelihood fit to the 1137 candidate events. We conclude that there is large CP violation in the neutral B meson system. A zero value for sin(2phi_1) is ruled out by more than six standard deviations.Comment: 25 pages, 16 figures, accepted for publication in Physical Review

    Measurement of CP-violation asymmetries in D0 to Ks pi+ pi-

    Get PDF
    We report a measurement of time-integrated CP-violation asymmetries in the resonant substructure of the three-body decay D0 to Ks pi+ pi- using CDF II data corresponding to 6.0 invfb of integrated luminosity from Tevatron ppbar collisions at sqrt(s) = 1.96 TeV. The charm mesons used in this analysis come from D*+(2010) to D0 pi+ and D*-(2010) to D0bar pi-, where the production flavor of the charm meson is determined by the charge of the accompanying pion. We apply a Dalitz-amplitude analysis for the description of the dynamic decay structure and use two complementary approaches, namely a full Dalitz-plot fit employing the isobar model for the contributing resonances and a model-independent bin-by-bin comparison of the D0 and D0bar Dalitz plots. We find no CP-violation effects and measure an asymmetry of ACP = (-0.05 +- 0.57 (stat) +- 0.54 (syst))% for the overall integrated CP-violation asymmetry, consistent with the standard model prediction.Comment: 15 page
