TL;DR: In this article, partial branching fractions and isospin asymmetries were obtained for the BABAR detector at the PEP-II e^+e^- collider.
Abstract: In a sample of 471×10^6 BB events collected with the BABAR detector at the PEP-II e^+e^- collider we study the rare decays B→K^(*)l^+l^-, where l^+l^- is either e^+e^- or μ^+μ^-. We report results on partial branching fractions and isospin asymmetries in seven bins of dilepton mass-squared. We further present CP and lepton-flavor asymmetries for dilepton masses below and above the J/ψ resonance. We find no evidence for CP or lepton-flavor violation. The partial branching fractions and isospin asymmetries are consistent with the Standard Model predictions and with results from other experiments.

TL;DR: In this article, the multiplicity distribution of primary charged hadron multiplicity distributions for non-single-diffractive events in proton-proton collisions at center-of-mass energies of 0.9, 2.36, and 7 TeV, in five pseudorapidity ranges from |eta|<0.5 to |eta |<2.4.
Abstract: Measurements of primary charged hadron multiplicity distributions are presented for non-single-diffractive events in proton-proton collisions at centre-of-mass energies of sqrt(s) = 0.9, 2.36, and 7 TeV, in five pseudorapidity ranges from |eta|<0.5 to |eta|<2.4. The data were collected with the minimum-bias trigger of the CMS experiment during the LHC commissioning runs in 2009 and the 7 TeV run in 2010. The multiplicity distribution at sqrt(s) = 0.9 TeV is in agreement with previous measurements. At higher energies the increase of the mean multiplicity with sqrt(s) is underestimated by most event generators. The average transverse momentum as a function of the multiplicity is also presented. The measurement of higher-order moments of the multiplicity distribution confirms the violation of Koba-Nielsen-Olesen scaling that has been observed at lower energies.

TL;DR: A significant research effort is required to more fully understand geometric adaptation in response to physical training, immobilisation/detraining, growth and aging.
Abstract: In addition to its size and the extent of its neural activation, a muscle's geometry (the angles and lengths of its fibres or fascicles) strongly influences its force production characteristics. As with many other tissues within the body, muscle displays significant plasticity in its geometry. This review summarises geometric differences between various athlete populations and describes research examining the plasticity of muscle geometry with physical training, immobilisation/detraining, growth and aging. Typically, heavy resistance training in young adults has been shown to cause significant increases in fascicle angle of vastus lateralis and triceps brachii as measured by ultrasonography, while high-speed/plyometrics training in the absence of weight training has been associated with increases in fascicle length and a reduction in angles of vastus lateralis fascicles. These changes indicate that differences in geometry between various athletic populations might be at least partly attributable to their differing training regimes. Despite some inter-muscular differences, detraining/unloading is associated with decreases in fascicle angle, although little change was shown in muscles such as vastus lateralis and triceps brachii in studies examining the effects of prolonged bed rest. No research has examined the effects of other interventions such as endurance or chronic stretching training. Few data exist describing geometric adaptation during growth and maturation, although increases in gastrocnemius fascicle angle and length seem to occur until maturation in late adolescence. Although some evidence suggests that a decrease in both fascicle angle and length accompanies the normal aging process, there is a paucity of data examining the issue; heavy weight training might attenuate the decline, at least in fascicle length. A significant research effort is required to more fully understand geometric adaptation in response to physical training, immobilisation/detraining, growth and aging.

TL;DR: It is concluded that in most well controlled and rigorously designed studies, utilizing appropriate outcome measures, respiratory muscle training has a positive influence upon exercise performance.
Abstract: Specific respiratory muscle training offers the promise of improved exercise tolerance and athletic performance for a wide range of users However, the literature addressing respiratory muscle training in healthy people remains controversial Studies into the effect of respiratory muscle training upon whole body exercise performance have used at least one of the following modes of training: voluntary isocapnic hyperpnea, flow resistive loading, and pressure threshold loading Each of these training modes has the potential to improve specific aspects of respiratory muscle function Some studies have demonstrated significant improvements in either time to exhaustion or time trial performance, whilst others have demonstrated no effect We present an overview of the literature that rationalizes its contradictory findings Retrospective analysis of the literature suggests that methodological factors have played a crucial role in the outcome of respiratory muscle training studies We conclude that in most well controlled and rigorously designed studies, utilizing appropriate outcome measures, respiratory muscle training has a positive influence upon exercise performance The mechanisms by which respiratory muscle training improves exercise performance are unclear Putative mechanisms include a delay of respiratory muscle fatigue, a redistribution of blood flow from respiratory to locomotor muscles, and a decrease in the perceptions of respiratory and limb discomfort
