The chi(b)(np) quarkonium states are produced in proton-proton collisions at the Large Hadron Collider at root s=7 TeV and recorded by the ATLAS detector. Using a data sample corresponding to an integrated luminosity of 4.4 fb(-1), these states are reconstructed through their radiative decays to Y(1S,2S) with Y ->mu(+)mu(-). In addition to the mass peaks corresponding to the decay modes chi(b)(1P,

OBJECTIVES: Breast Imaging-Reporting and Data System (BI-RADS) mammographic density categories are associated with considerable interobserver variability. Automated methods of measuring volumetric breast density may reduce variability and be valuable in risk and mammographic screening stratification. Our objective was to assess agreement of mammographic density by a volumetric method with the radi

BACKGROUND AND OBJECTIVE: Severe idiopathic pulmonary fibrosis is associated with an increased risk of cardiovascular disease and gastro-oesophageal reflux, which may influence prognosis. We evaluated associations between cardiovascular and antacid medications, and mortality, in oxygen-dependent pulmonary fibrosis (PF) of unknown cause.METHODS: Prospective population-based study of adults starting

With the advent of the Functional Mock-up Interface (FMI) standard, exchanging dynamic models between modeling and simulation tools has been greatly simplified. At the core of it, FMI is a standardized and unified model execution interface for dynamic models. FMI has gained widespread adoption among users and numerous commercial and open source tools implement support for the standard. In this art

Convection is shown in earlier studies to improve the thermal contact between heat exchanger and borehole wall in water-filled boreholes. This study investigates the effect of convection on the required borehole length for a ground-coupled heat pump installation. Artificial convection was induced by an ordinary groundwater pump during a multi-injection rate thermal response test (MIR-TRT). For com

This study investigated effects of surfactant sodium dodecylbenzene sulfonate (SDBS) on flow boiling heat transfer of ethylene glycol/water mixtures in a vertical minitube. Experiments were performed using solutions containing 300 ppm by weight of surfactant and the results were compared with those of pure mixture. Local heat transfer coefficient was measured and found to be dependent on the mass

We describe a beamline based on a plane-grating monochromator and an end-station designed for high resolution photoemission and photoabsorption spectroscopy on surfaces and interfaces using undulator radiation in the energy range 30 1500 eV. The general design of the beamline is based on a horizontally focusing pre-mirror, an SX-700 type of plane-grating monochromator and re-focusing optics of Kir

A strong low-energy shake-up satellite for CO adsorbed on Pd is observed. The occurrence of the satellite is established for the CO/1 ML Pd/Mo(110) system at a coverage where CO adsorbs exclusively on-top. Comparisons with CO adsorbed on Pd single-crystal surfaces and small supported Pd particles indicate that the strongly increased satellite intensity is due to the decreased CO-Pd interaction str

BACKGROUND: Increased knee abduction angle during activity is suggested to be a risk factor for sustaining an anterior cruciate ligament (ACL) injury or developing patellofemoral pain syndrome (PFPS). Knowledge of the modifiable mechanisms that are associated with increased knee abduction will aid in the appropriate design of preventive and rehabilitative strategies for these injuries.OBJECTIVE: O

While previous research has advocated the use of online sales channels as a driver for international expansion, the nature of the relationship between e-commerce and international sales is still unexplored. The purpose of this paper is to create a parsimonious model where we investigate whether, and to what extent, strategies pertaining to the geographical scope of international operations moderat

High-pressure X-ray diffraction, Mössbauer, and Raman studies in the antiferromagnetic insulators RFeO3 orthorhombic perovskites (R = Pr, Eu, Lu) disclose an unusual phenomena of a reversible first-order isostructural phase transition around 50 GPa concurring with an abrupt ∼ 5% volume decrease. It is shown experimentally that this transformation concurs with, and is driven by, a high-to-low-spin

Public diplomacy is the communication of an international actor’s policies to citizens of foreign countries. These citizens might include civil society representatives, nongovernmental organisations, multinationals, journalists and media institutions, specialists across different sectors of industry, politics and culture, and members of the general public. They are typically engaged by actors like

To our knowledge, this is the first prospective study using validated questionnaires to assess patient-relevant outcomes after arthroscopic partial meniscectomy. Data from the Knee Injury and Osteoarthritis Outcome Score (KOOS), the SF-36 Medical Outcomes Study Short-Form Health Survey, and the Lysholm Knee Scoring Scale were available for 74 consecutive patients (50 males, 24 females; mean age, 4
