K ikuyu grass ( Pennisetum clandestinum ) is a perennial pasture species with a spring to autumn growth habit. Although it is usually grazed without ill effect, spasmodic incidents of poisoning in cattle 1 and, to a much lesser extent, sheep 2 and goats, 3 have been encountered.

the objective of this work is the estimation of vocal tremor in patients with spasmodic dysphonia before and after treatment, and the comparison of their tremor characteristics with those estimated from healthy speakers. as an outcome, a new tremor attribute is introduced, the deviation of the modulation level and a novel method is proposed for classifying speakers according to the prevalence o...

It is currently unclear whether the brain plans movement kinematics explicitly or whether movement paths arise implicitly through optimization of a cost function that takes into account control and/or dynamic variables. Several cost functions are proposed in the literature that are very different in nature (e.g., control effort, torque change, and jerk), yet each can predict common movement cha...
