The distance to the Orion Nebula Cluster [PDF]

, 2006
The distance to the Orion Nebula Cluster (ONC) is estimated using the rotational properties of its low-mass pre main-sequence (PMS) stars. Rotation periods, projected equatorial velocities and distance-dependent radius estimates are used to form an ...

Conceptual and socio-cognitive support for collaborative learning in videoconferencing environments [PDF]

, 2006
Studies have shown that videoconferences are an effective medium for facilitating communication between parties who are separated by distance. Furthermore, studies reveal that videoconferences are effective when used for distance learning, particularly ...

Recognition of transposed melodies: Effects of pitch distance and harmonic distance [PDF]

Psychonomic Bulletin & Review, 2017
People easily recognize a familiar melody in a previously unheard key, but they also retain some key-specific information. Does the recognition of a transposed melody depend on either pitch distance or harmonic distance from the initially learned instances?

Effective gravitational mass of the Ay\'{o}n-Beato and Garc\'{\i}a metric

, 2015
In this paper, we calculate the effective gravitational mass of Ay\'{o}n-Beato and Garc\'{\i}a regular (non-singular) static spherically symmetric asymptotically Minkowskian metric that is a solution to Einstein's equations coupled with a nonlinear ...

Nonlocal Effective Field Equations for Quantum Cosmology [PDF]

, 2005
The possibility that the strength of gravitational interactions might slowly increase with distance, is explored by formulating a set of effective field equations, which incorporate the gravitational, vacuum-polarization induced, running of Newton's ...

Analog gravity from field theory normal modes?

, 2001
We demonstrate that the emergence of a curved spacetime ``effective Lorentzian geometry'' is a common and generic result of linearizing a field theory around some non-trivial background. This investigation is motivated by considering the large number of `

Results of the Childhood Cancer and Leukaemia Group's United Kingdom Relapsed Wilms Tumour Trial

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background The United Kingdom relapsed Wilms tumour (UKW‐R) trial aimed to improve the historically low survival rates after relapse of Wilms tumour (WT) through a prospective national risk‐stratified protocol. The trial also evaluated efficacy and toxicity of high‐dose melphalan.
