Posture Noise and the Measured Probability to Fall
Radostina K. Koleva, A. Widom, D. Garelick +9
Experimental evidence is presented connecting small fluctuations in the posture of a quiet standing subject and the probability that the subject will have an accidental fall within…
Superconducting gap anisotropy within the framework of a simple exchange model for layered cuprates. The theory of HTSC
T. M. Mishonov, A. A. Donkov, R. K. Koleva +1
The oxygen O2p_sigma and copper Cu4s and Cu3d_x^2-y^2 orbitals are involved in a simple LCAO model for determination of the conduction band and the oxygen-oxygen hopping is conside…
Correlated hip motions during quiet standing
R. K. Koleva, A. Widom, D. Garelick +3
Kinematic measurements of two simultaneous coordinates from postural sway during quiet standing were performed employing multiple ultrasonic transducers. The use of accurate acoust…
Posture Sway and the Transition Rate for a Fall
R. K. Koleva, A. Widom, D. Garelick +1
Postural body sway displacements for quiet standing subjects (measured with a new ultrasonic device) are reported. Two of the well known strategies for balancing, namely ankle and…
