An Arabidopsis cab gene homologous to Cab-8 of tomato.

THE Cab CURVE

We characterize the defining equation of a plane algebraic curve with exactly one rational place Q at infinity, then give a basis of L(mQ) with pairwise distinct pole orders at Q. The defining equation can be regarded as a generalization of the Weierstrass form of a hyperelliptic curve. In this informal note I give an English proof of the results of the Cab curve found by Miura [4, 5, 6]. Throu...

CAB: Connectionist Analogy Builder

The ability to make informative comparisons is central to human cognition. Comparison involves aligning two representations and placing their elements into correspondence. Detecting correspondences is a necessary component of analogical inference, recognition, categorization, schema formation, and similarity judgment. Connectionist Analogy Builder (CAB) determines correspondences through a simp...

Gaudry's Variant against Cab Curves

Gaudry has described a new algorithm (Gaudry’s variant) for the discrete logarithm problem (DLP) in hyperelliptic curves. For a hyperelliptic curve of a small genus on a finite field GF(q), Gaudry’s variant solves for the DLP in time O(q2+2). This paper shows that Cab curves can be attacked with a modified form of Gaudry’s variant and presents the timing results of such attack. However, Gaudry’...

SUMO unloads the Kap114 cab.

Nucleocytoplasmic transport is an essential mechanism in all eukaryotic cells, for which the basic mechanisms seemed well understood. Transport receptors of the importin b/karyopherin family recognize, translocate and discharge cargo. Key to directed transport is the GTPase Ran, which determines compartment-specific interactions between receptors and their cargo. In this issue of The EMBO Journ...
