Neuromechanical Control of Paddle Juggling
The objective of this research is to discover the rules by which the human nervous system controls the cyclic task of paddle juggling. The existence of separate feedforward and feedback control signals is hypothesized, and the feedforward control system is completely identified using tools from dynamical systems theory. Using this knowledge progress is made in identifying the feedback control s...
متن کاملContact dissociation from paddle leads: a report of two cases.
Case 1 A 60-year-old white male developed neck and bilateral shoulder pain two and a half years ago. There was no history of trauma. He had numbness and paresthesias along the ulnar border of his left forearm and in his left ring and little fingers. Pinprick sensibility was decreased along the medial and lateral borders of his left forearm and in his left middle finger. Reflexes and motor testi...
متن کاملA new type of paddle-wheel coordination complex.
In the presence of Na(+) ions, the reaction of the ligand 2-hydroxy-1,3-bis-(3-oxo-3-(2-hydroxyphenyl)-propionyl)-benzene, H5L4, with M(AcO)2 salts (M = Mn, Co) gathers the conditions for the assembly of coordination complexes (NBu4)3[M2Na2(H2L4)3] (M = Mn(II) 1 and Co(II) 2), which exhibit a new paddle-wheel structure. The features of this new category of compounds are discussed as well as the...
متن کاملOptically trapped and driven paddle-wheel
We demonstrate the control and rotation of an optically trapped object, an optical paddle-wheel, with the rotation direction normal to the beam axis. This is in contrast to the usual situation where the rotation is about the beam axis. The paddle-wheel can be optically driven and moved to any position in the field of view of the microscope, which can be of interest for various biological applic...
متن کاملTransthoracic resistance in human defibrillation. Influence of body weight, chest size, serial shocks, paddle size and paddle contact pressure.
Successful defibrillation depends on delivery of adequate electrical current to the heart; one of the major determinants of current flow is transthoracic resistance (TTR). To study the factors influencing TTR, we prospectively collected data from 44 patients undergoing emergency defibrillation. Shocks of 94-450 J delivered energy were administered from specially calibrated Datascope defibrillat...
