Methods to print patterns of mammalian cells to various substrates with high resolution offer unique possibilities to contribute to a wide range of fields including tissue engineering, cell separation, and functional genomics. This manuscript details experiments demonstrating that BioLP TM Biological Laser Printing, can be used to rapidly and accurately(More)
A technique by which to print patterns and multilayers of scaffolding and living cells could be used in tissue engineering to fabricate tissue constructs with cells, materials, and chemical diversity at the micron scale. We describe here studies using a laser forward transfer technology to print single-layer patterns of pluripotent murine embryonal(More)
Cell printing has been popularized over the past few years as a revolutionary advance in tissue engineering has potentially enabled heterogeneous 3-D scaffolds to be built cell-by-cell. This review article summarizes the state-of-the-art cell printing techniques that utilize fluid jetting phenomena to deposit 2- and 3-D patterns of living eukaryotic cells.(More)
It is frequently remarked that designers of computer vision algorithms and systems cannot reliably predict how algorithms will respond to new problems. A variety of reasons have been given for this situation, and a variety of remedies prescribed [99, 213, 33]. Most of these involve, in some way, paying greater attention to the domain of the problem and to(More)
We outline a policy conflict analysis process for the analysis of newly specified federation-level policies against previously deployed local/federation policies. The process is generic in the sense that it can be employed by each domain participating in a federation to help maintain the consistency of their local system with that of the federation. The(More)
We have investigated the electrochemical, spectroscopic, and electroluminescent properties of a family of diimine complexes of Ru featuring various aliphatic side chains as well as a more extended pi-conjugated system. The performance of solid-state electroluminescent devices fabricated from these complexes using indium tin oxide (ITO) and gold contacts(More)
Resource access control policies for an organization are often derived from best practice standards or from high level business policies. To ensure that access control is enforced effectively, these business policies need to be translated into deployable system configurations or lower level policies for multiple diverse systems. These target policy(More)
We present a dominance detection algorithm as part of a policy authoring process that makes extensive use of semantic models to perform a novel dominance detection of access control policies, where groups of deployed policies are considered in unison to discover redundancy. The approach is targeted towards the pre-deployment stage of the policy authoring(More)
Traditionally, network management tasks manually performed by system administrators include monitoring alarms based on collected statistics across many heterogeneous systems, correlating these alarms to identify potential problems or changes to management policies and responding by performing system re-configurations to ensure optimal performance of network(More)
