Magnetic conductivity and Chern-Simons Term in Holographic Hydrodynamics of Charged AdS Black Hole
We study the effects of the Chern-Simons term in the hydrodynamics of the
five-dimensional Reissner-Nordstrom-AdS background. We work out the decoupling
problem of the equations of motion and calculate the retarded Green functions
explicitly. We then find that the Chern-Simons term induces the magnetic
conductivity caused by the anomaly effect. It is increasing function of
temperature running from a non-zero value at zero temperature to the twice the
value at infinite temperature.Comment: 19 pages, 2 figures; v2 discussion on classification of perturbation
fields based on helicity base, third order in dispersion relation and more
discussion on magnetic conductivity are added, some typos are corrected and
references are added; v3 published versio
PRELIMINARY ASSESSMENT OF THE EFFECT OF TRAPEZE POSTURES ON RIGHTING FORCE IN SAILING
This study examined the effect of change of âTrapezeâ postures in sailing on the horizontal force for righting the boat. Three healthy university sailors participated. The subjects were instructed to successively change their trapeze posture. The traction force of the wire was measured from which its horizontal component for righting the boat (FH) was computed. A distinct change of FH was observed when the subjects extend their legs during trapezing. From this result, it can be suggested that the change of the trapeze posture by extending the leg linked to expand the angle between the wire and mast, thereby contributing to the increase the resultant FH
A CASE STUDY OF âK-TIEâ ASSISTED INSTRUCTION KAI TO âCLAPPING HANDSâ AS A RECREATION ACTIVITY
The purpose of this study was to identify the causes of rejection of papers from conference proceedings and to present guidelines to limit the number of papers rejected from the Proceedings of the XXIVth International Symposium on Biomechanics in Sports hosted by the University of Salzburg, Austria. Scientists (n=95) with extensive experience in reviewing papers completed a survey. Each scientist selected their five most common reasons for rejecting papers. All scientists selected 'unsound experimental designâ and 'lack of clarityâ in one or more sections as common reasons for rejecting papers from proceedings. Other common reasons were poor identification of the problem (53), and poor analytical methods (65). Guidelines for authors arose from the study
