A Morphological Approach to the Pulsed Emission from Soft Gamma Repeaters

We present a geometrical methodology to interpret the periodical light curves of Soft Gamma Repeaters based on the magnetar model and the numerical arithmetic of the three-dimensional magnetosphere model for the young pulsars. The hot plasma released by the star quake is trapped in the magnetosphere and photons are emitted tangent to the local magnetic field lines. The variety of radiation morphologies in the burst tails and the persistent stages could be well explained by the trapped fireballs on different sites inside the closed field lines. Furthermore, our numerical results suggests that the pulse profile evolution of SGR 1806-20 during the 27 December 2004 giant flare is due to a lateral drift of the emitting region in the magnetosphere.Comment: 7 figures, accepted by Ap

BIOMECHANICAL CHARACTERISTICS OF WHOLE-BODY FAST REACHING MOVEMENTS

Executing a whole-body fast reaching movement is an essential skill in many competitive sports. The present study investigated this kind of movement by biomechanical analyses. Five male university athletes and five fencing team members volunteered as subjects in this study. Each subject was asked to perform whole-body fast reaching movements and end at a stable posture. A motion capture system was used to record the kinematic data. The results demonstrate that the fencers moved the upper extremities earlier than the lower extremities, and the proximal segments started slightly before the distal segments. In conclusion, in executing whole-body fast reaching movements, upper and lower extremities work together as one functional unit, and there may be slightly different strategies adopted by each individual according to their exercise habits
