Visceral movement due to impact loading is believed to play a role in the locomotor-respiratory coupling (LRC) that has been detected in a number of mammalian species. In the bird and bat species in which LRC has been described, the effect of the wing muscles on the timing of respiration appears to be a dominant influence. To test the hypothesis that LRC(More)
Destruction of the nasal septum and nasal bones by Mycobacterium leprae and subsequent infection is still seen regularly in leprosy endemic areas. The social stigma associated with this deformity is significant. Many different procedures have been developed to reconstruct the nose. Patients operated on at Anandaban Hospital and the Green Pastures Hospital(More)
The essential dimension is a numerical invariant of an algebraic group G which may be thought of as a measure of complexity of G-torsors over fields. A recent theorem of N. Karpenko and A. Merkur-jev gives a simple formula for the essential dimension of a finite p-group. We obtain similar formulas for the essential p-dimension of a broad class of groups,(More)

This paper shows that the number of independent parameters required to describe an Albert algebra up to isomorphism is at most 7. In other words, the essential dimension of the split group of type F4 over a field of characteristic not 2 or 3 satisfies ed(F4) ≤ 7. This is achieved by reducing the structural group from the full 52-dimensional automorphism(More)
This paper gives a new upper bound for the essential dimension and the essential 2-dimension of the split simply connected group of type E7 over a field of characteristic not 2 or 3. The essential dimension of an algebraic group G is a numerical invariant which measures the complexity of its G-torsors. The essential dimensions of the exceptional algebraic(More)
