Hydrophobicity

As anyone who has looked at a petunia or a pansy can testify, plants generate flowers with characteristic numbers and patterns of organs. The floral organs are derived from a pool of stem cells called the floral meristem. In wild-type Arabidopsis thaliana flowers (shown at lower left) the meristem gives rise to four sepals that enclose the bud, four white petals, six pollen-bearing stamens and ...

Parity Lost and Parity Regained

RAID storage systems protect data from storage errors, such as data corruption, using a set of one or more integrity techniques, such as checksums. The exact protection offered by certain techniques or a combination of techniques is sometimes unclear. We introduce and apply a formal method of analyzing the design of data protection strategies. Specifically, we use model checking to evaluate whe...

The psychological unconscious. Found, lost, and regained.

In response to Greenwald's article on contemporary research on unconscious mental processes, the authors address three issues: (a) the independence of much recent research and theory from psychodynamic formulations; (b) the broad sweep of the psychological unconscious, including implicit perception, memory, thought, learning, and emotion; and (c) the possibility that the analytic power of uncon...

Paradigm Regained: Abstraction Mechanisms for Access Control

Access control systems must be evaluated in part on how well they enable one to distribute the access rights needed for cooperation, while simultaneously limiting the propagation of rights which would create vulnerabilities. Analysis to date implicitly assumes access is controlled only by manipulating a system's protection state—the arrangement of the access graph. Because of the limitations of...
