We show that a sheared 2–D force–free field can evolve in a quasi–static way towards an open configuration, and apply this result to a qualitative theory of two–ribbon solar flares.

ABSTRACT Pak1 protein kinase of Schizosaccharomyces pombe, a member of the p21-GTPase-activated protein kinase (PAK) family, participates in signaling pathways including sexual differentiation and morphogenesis. The regulatory domain of PAK proteins is thought to inhibit the kinase catalytic domain, as truncation of this region renders kinases more active. Here we report the detection in the two-hybrid system of the interaction between Pak1 regulatory domain and the kinase catalytic domain. Pak1 catalytic domain binds to the same highly conserved region on the regulatory domain that binds Cdc42, a GTPase protein capable of activating Pak1. Two-hybrid, mutant, and genetic analyses indicated that this intramolecular interaction rendered the kinase in a closed and inactive configuration. We show that Cdc42 can induce an open configuration of Pak1. We propose that Cdc42 interaction disrupts the intramolecular interactions of Pak1, thereby releasing the kinase from autoinhibition.

We propose a surgical manipulator system supporting surgical treatment and intraoperative disease diagnosis. Manipulators fit vertical-magnetic-field open-configuration magnetic resonance (MR) imagers, and surgical tools on the end of the manipulator arm are interchangeable. We evaluated maneuverability using slave manipulators through a surgical input device consisting of a pair of master devices and a console. We conducted basic suturing tasks in training material that mimics human tissue and thin blood vessels.
