Single-channel recordings of a voltage-dependent potassium channel in brown adipocytes of the rat confirm recordings of macroscopic currents. Single-channel conductance (gamma) is 8 pS at 20 degrees C in KF solution inside vs. a modified Ringer's solution outside. With KCl solution outside, gamma is 17 pS for outward currents and 21 pS for inward currents.(More)
User-driven access control improves the coarse-grained access control of current operating systems (particularly in the mobile space) that provide only all-or-nothing access to a resource such as the camera or the current location. By granting appropriate permissions only in response to explicit user actions (for example, pressing a camera button),(More)
Threshold schemes provide a means through which two groups can communicate if and only if a certain number of members participate. Existing threshold schemes focus on generating a group public and secret key pair which can be used to encrypt or sign. The scheme described in this paper uses a bilinear pairing to establish a secret key that can be used by two(More)
