Conservation rules, their breakdown, and optimality in Caenorhabditis sinusoidal locomotion

Kavli Affiliate: Paul W. Sternberg | Summary:Undulatory locomotion is common to nematodes as well as to limbless vertebrates, but its control is not understood in spite of the identification of hundred of genes involved in Caenorhabditis elegans locomotion. To reveal the mechanisms of nematode undulatory locomotion, we quantitatively analyzed the movement of C. elegans with […]

A classical key distribution system based on Johnson (like) noise – How secure?

Kavli Affiliate: Amnon Yariv | Summary:We present a comprehensive analysis of the Johnson (like) noise based classical key-distribution scheme presented by Kish [1]. We suggest two passive attack strategies that enable an adversary to gain complete knowledge of the exchanged key. The first approach exploits the transient response of the voltage difference on the transmission […]

Algebras of curvature forms on homogeneous manifolds

Kavli Affiliate: Mikhail Shapiro | Summary:Let C(X) be the algebra generated by the curvature 2-forms of the standard hermitian line bundles over the complex homogeneous manifold X=G/B. We calculate the Hilbert polynomial of C(X) and give its presentation as a quotient of a polynomial ring. In particular, we show the dimension of C(X) is equal […]
