First amplitude analysis of B<sup>+</sup>→J/...
<p>The first amplitude analysis B<sup>+</sup>→J/ψφK<sup>+</sup>, J/ψ→μ<sup>+</sup>μ<sup>-</sup>, φ→K<sup>+</sup>K<sup>-</sup> events is performed in Isobar approximation using all six degrees of freedom of their decay kinematics and 3 fb<sup>-1</sup> of pp collision data collected at √s=7-8 TeV …

Physical Modeling and Analysis of Seismic Data from a Simulated Fractured Medium
… to examine variations of seismic re ection amplitudes with source-receiver o set and azimuth (AVAZ). The intent is to extract information about the fracture orientation and magnitude of the anisotropy of a naturally fractured medium. The simulated fractured medium is constructed from …

Amplitude Analyses of the D meson(+),Dmeson(+)(s) Going to Kaon(-)kaon(+)pion(+) and D Meson(0) Going to Kaon(o)(s)kaon(+)kaon(-) Final States
Amplitude analysis of the D+,D+s→ K-K+p+ and D0→KosK+K - final states are presented using the data collected by the Fermilab high energy photoproduction experiment E831(FOCUS), during 96--97. Our data are fit to a model consisting of a sum of Breit-Wigner amplitudes for the intermediate …

Observation of J/psi p resonances consistent with pentaquark states in Lambda_b^0 to J/psi K^- p decays
… detector from 7 and 8 TeV $pp$ collisions. An amplitude analysis was performed which utilized all six kinematic degrees of freedom in the decay. It was shown that adequate descriptions of the data are unattainable with only $K^- p$ resonances in the amplitude model. For satisfactory fits of the …

Azimuthal P-wave AVA Inversion for Fracture Orientation and Density
… to analyze variations of seismic reflection amplitudes with incident and azimuthal angles (AVAZ). The intent is to extract the information about the fracture orientation and intensity of a fractured medium. The effective compliance tensor for a fractured medium can be written as the sum of …

Geophysical Characterisation and Evolutionary Model of the Quaternary sediments in the North Offaly region of Central Ireland
… boreholes and 190 petrographic and particle size analysis samples were used to produce Quaternary geological and depth to bedrock maps for the 600 Km² research area located in the North Offaly region of central Ireland. Based on the mapping, the area was subdivided into four physiographic units …

Determination of the X(3872) Meson Quantum Numbers
… full angular phase-space. The 5-dimensional analysis shows that 1++ hypothesis is preferred with overwhelming significance. The only alternative assignment allowed by the previous measurements, JPC = 2-+, is rejected with a confidence level equivalent to more than eight Gaussian standard …

Partial discharge signal propagation, modelling and estimation in high voltage transformer windings
… approach developed. A technique of split winding analysis is introduced for both types of model. The derivation of the capacitive network considers the source location of a PD by defining the PD signal propagation in two directions. At the source, the currents are equal in magnitude and are …

Probing the Mantle Transition Zone beneath the Central Pacific Region Using PP Precursors
… mantle beneath the Central Pacific. However, the analysis of PP precursors (P-wave counterparts of SS precursors) in this area and elsewhere is scarce. In this study, we compare the field observations of PP precursors and the results from thermodynamic modelings at various thermal and …

Seismic amplitude fidelity study for quantitative analysis and its relation to stack-based signal-to-noise ratio estimation using the SEAM Arid model, with application to field data from the Powder River Basin
… quantitative tools to assess the seismic amplitude fidelity for quantitative interpretation in several land acquisition designs, and establish a signal-to-noise ratio (SNR) threshold for adequate quantitative analysis in complex near-surface environments. The first part of the research …

Motor control strategies in response to unexpected disturbances of dynamic postural control in people with and without low back pain
… by unexpected rapid deceleration impulses (amplitude: 2 m/s; duration: 100 ms; 200 ms after heel contact) at 1m/s baseline velocity. A total number of 5 (study 1) and 15 (study 2) right sided perturbations were applied during walking trials. Muscular activities were assessed by surface …
