It has been suggested that residual cytotoxic sodium dodecyl sulfate (SDS) is responsible for the low levels of cell in-growth observed in SDS decellularized tissues. To determine whether this is the case, we used 2 washing methods to remove residual SDS and extensive biochemical, mechanical, and structural analyses to determine the effects of SDS-based(More)
We are developing a decellularized bone-anterior cruciate ligament (ACL)-bone allograft for treatment of ACL disruption in young or active patients. This study demonstrates the feasibility of seeding decellularized ACL tissue with primary ligament fibroblasts. Porcine ACLs were decellularized by one of three protocols, each differing only by the(More)
Although the end of the Cold War minimized the threat of massive open ocean naval combat, new littoral warfare missions and scenarios involving both combined arms and joint allied operations, have emerged. New threats, missions and operating environments present a greater challenge to target identification, reaction time, command and control, and tracking(More)
Some classes of real-time systems function in environments which cannot be modeled with static approaches [Koo96]. In such environments, the arrival rates of events which drive transient computations may be unknown. Also, the periodic computations may be required to process varying numbers of data elements per period, but the number of data elements to be(More)
The Navy is a large user of real-time systems. A modern surface ship is deployed with hundreds of computers which are required for the ship to perform its mission. The Navy is moving away from using “niche” market components to meet its real-time computing needs and towards distributed processing using Commercial-Off-The-Shelf (COTS) computing components.(More)
In this paper a detailed methodology for automated reengineering of computer-based systems is presented. The methodology has evolved through application to portions of the AEGIS Weapons System. The methodology contains many enhancements over [6], incorporating experience gained through the reengineering of the weapons selection module and the surface(More)
