We study the elliptic flow v2 of multi-strange hadrons such as the φ, Ξ and Ω as a function of transverse momentum in the recombination and fragmentation model and compare to a standard hydrodynamic calculation. We find that the measurement of v2 for the φ and Ω will allow for the unambiguous distinction between parton recombination and statistical hadro-chemistry to be the dominant process in ...

We report the measurement of cavity propagation losses in nearly single-mode semiconductor waveguide-coupled ring and disk microcavity optical resonators. Using a novel 10.5m-diameter ring resonator, we measure transverse electric (TE) and transverse magnetic (TM) field intensity losses in 0.35m-wide ring waveguide cavities in the 1.55m-wavelength region. We present the experimental results for...

We discuss experimental techniques for measurement of the density of beam particles in both the transverse and longitudinal phase space. The second moments of a two-dimensional density in conjugate coordinates are combined to form the emittance, which remains invariant under idealized beam transport. Four different methods of emittance measurement are presented, as will be implemented at the Br...

The beam transverse emittance control and preservation in all the acceleration chain from the proton source to the 7TeV colliding beams is fundamental for ensuring high luminosity runs at the CERN Large Hadron Collider (LHC). This paper aims at discussing the emittance measurement methods and present status in the acceleration stages from the Proton Synchrotron Booster (PSB) injection at p=50Me...

Determination of microlensing parameters in the gravitationally lensed quasar Q2237+0305 from the statistics of high magnification events will require monitoring for more than 100 years (Wambsganss, Paczynski & Schneider 1990). However we show that the effective transverse velocity of the lensing galaxy can be determined on a more realistic time-scale through consideration of the distribution o...

OBJECTIVE To compare transverse abdominis (TrA) contractility in stroke patients with hemiparesis and healthy adults using musculoskeletal ultrasonography. METHODS Forty-seven stroke patients with hemiparesis and 25 age-matched healthy control subjects participated in this study. Stroke patients were divided into three groups on the basis of their degree of ambulation. Group A consisted of 9 ...

The deep transverse metatarsal ligaments play an important role in stabilizing the metatarsal bones and manipulating foot transverse arch deformation. However, the biomechanical research about transverse metatarsal ligaments in the foot maneuver is quite few. Due to the difficulties and lack of better measurement technology for these ligaments experimental monitor, the load transfer mechanism a...

We have obtained observations of the magnetar XTE J1810–197 with the Very Long Baseline Array at two epochs separated by 106 days, at wavelengths of 6 cm and 3.6 cm. Comparison of the positions yields a proper motion value of 13.5±1.0 mas yr−1 at an equatorial position angle of 209.4±2.4 (east of north). This value is consistent with a lower-significance proper motion value derived from infrare...
