Boolean networks are important models of biochemical systems, located at the high end of the abstraction spectrum. A number of Boolean gene networks have been inferred following essentially the same method. Such a method first considers experimental data for a typically underdetermined "regulation" graph. Next, Boolean networks are inferred by using biological constraints to narrow the search s...

We present Griffin, a hybrid storage device that uses a hard disk drive (HDD) as a write cache for a Solid State Device (SSD). Griffin is motivated by two observations: First, HDDs can match the sequential write bandwidth of mid-range SSDs. Second, both server and desktop workloads contain a significant fraction of block overwrites. By maintaining a log-structured HDD cache and migrating cached...

After reading this article, the reader should be able to: • describe requirements that would lead to success with immediate implant placement and loading. • describe important surgical considerations to increase the survival of immediate implant restoration. • discuss advantages in the single appointment fabrication of computer-assisted designed and machined porcelain for implant restoration. •...

GRIFFIN is a joint research project of the VU University Amsterdam and the University of Groningen. The GRIFFIN project develops notations, tools and associated methods to extract, represent and use architectural knowledge that currently is not documented or represented in the system. The research is carried out in a consortium with various industries, both large and small, that provide case st...
