Validation of the Omni-cycle scale of perceived exertion in the elderly
This study examined the concurrent and construct validity of the OMNI-Cycle Rating of Perceived Exertion (RPE) Scale, using elderly men and women. Seventy-six participants performed a load-incremented cycle-ergometer exercise test. Concurrent validity was determined by correlating OMNI-RPE responses with oxygen uptake, relative peak oxygen uptake, pulmonary ventilation, heart rate, respiratory rate, and respiratory-exchange ratio during a load-incremented cycle-ergometer protocol. Construct validity was established by correlating RPE derived from the OMNI-Cycle Scale with RPE from the Borg (6–20) Scale. Multilevel, mixed linear-regression models indicated that OMNI-RPE distributed as a significant (p < .05) positive linear function (r = .81–.92) for all physiological measures. OMNI-RPE was positively (p < .01) and linearly related to Borg-RPE in elderly men (r = .97) and women (r = .96). This study demonstrates both concurrent and construct validity of the OMNI-Cycle RPE Scale. These findings support the use of this scaling metric with elderly men and women to estimate RPE during cycle-ergometer exercise
Validation of the Italian version of the OMNI Scale of Perceived Exertion in a sample of Italian-speaking adults
The purpose was to examine whether the translation of verbal descriptors from English to Italian affects the validity of the OMNI Scale of Perceived Exertion. 82 people for whom Italian was the primary language performed an orientation trial and a maximal graded exercise test on a cycle ergometer. Ratings of perceived exertion for the overall body and physiological responses were measured during each exercise stage. Significant correlations were found between perceptual responses of the Italian version of the OMNI Cycle Scale of Perceived Exertion and oxygen uptake, pulmonary ventilation, heart rate, respiratory rate, and respiratory exchange ratio responses to a maximal graded exercise test on a cycle ergometer. These findings indicate that the Italian version of the OMNI Scale of Perceived Exertion gives a valid estimate of effort during cycle ergometer exercise

Differential Effects of Continuous versus Discontinuous Aerobic Training on Blood Pressure and Hemodynamics
The purpose of this study was to compare the hemodynamic, arterial stiffness, and blood flow changes following four weeks of either continuous or discontinuous aerobic exercise in adults. Forty-seven subjects between the ages of 18 and 57 were recruited for one month of either continuous aerobic treadmill work for 30 minutes at 70% max heart rate or 3 bouts of 10 minutes of exercise at 70% of max heart rate with two 10 minute break periods in between, totaling 30 minutes of aerobic work. Following exercise, both CON and DIS groups demonstrated a significant improvement in VO2max (CON 35.39±1.99 to 38.19±2.03; DIS 36.18±1.82 to 39.33±1.75), heart rate max (CON 183.5±3.11 to 187.17±3.06; DIS 179.06±2.75 to 182±2.61), decreases in SBP(CON 119±1.82 to 115.11±1.50; DIS 117.44±1.90 to 112.67±1.66), DBP(CON 72.56±1.65 to 70.56±1.06; DIS 71.56±1.59 to 69.56±1.43), augmentation index (CON 17.17±2.17 to 14.9±1.92; DIS 19.71±2.66 to 13.91±2.46), central pulse wave velocity (CON 8.29±0.32 to 6.92±0.21; DIS 7.85±0.30 to 6.83±0.29), peripheral PWV (CON 9.49±0.35 to 7.72±0.38; DIS 9.11±0.37 to 7.58±0.47), and significant increases in average forearm blood flow (CON 4.06±0.12 to 4.34±0.136; DIS 4.26±0.18 to 4.53±0.15), peak FBF following reactive hyperemia (CON 28.45±0.094 to 29.96±0.45; DIS 29.29±0.46 to 30.6±0.38) area under the curve of FBF (CON 28.65±1.77 to 30.4±1.08; DIS 30.52±1.9 to 31.67±1.44) and AUC peak FBF following RH (CON 222.3±5.68 to 231.95±4.42; DIS 230.81±6.91 to 237.19±5.39. These data suggest that for healthy people either four weeks of continuous or discontinuous aerobic training is effective in improving measures of fitness and vascular health

Efficient Computation of Dynamic Stability Data with a Linearized Frequency Domain Solver.
Determination of aeroelastic stability boundaries for full aircraft configu-
rations by solving the time-accurate unsteady Reynolds-averaged Navier-Stokes (RANS)
equations is recognized as extremely computationally expensive or impractical. This is due
to the wide range of
flight conditions, frequencies, and structural deformation mode shapes
that must be examined to ensure a configuration is free from
flutter. Nonetheless there
is an increasing demand within the aerospace industry for accurate
utter analysis in the
transonic regime, which can only be satisfied with the use of high-fidelity RANS codes.
Hence we are motivated to seek a more efficient numerical method. By assuming that
perturbations to the
ow are small and harmonic, we can derive an efficient alternative
method by linearization of the RANS equations, a linearized frequency domain (LFD)
solver. With this approach the unsteady simulation reduces to a single non-linear steady
computation followed by a single linear simulation in the frequency-domain. This method
is not new, but has principally been applied to turbomachinery so far. The contribution
of this paper twofold: firstly to show that LFD is sufficiently accurate and reliable for
applications to aeroelastic problems that occur in external aerodynamics, and secondly to
demonstrate the speed-up that can be expected over full unsteady computations. Viscous
transonic analysis is carried out on complex geometries in three-dimensions. The results
show good agreement with full unsteady simulation and experiment, and a reduction in
computational costs up to one order of magnitude is demonstrated
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV
The prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region
