This paper presents RESIST, a recursive test pattern generation (TPG) algorithm for path delay fault testing of scan-based circuits. In contrast to other approaches , it ezploits the fact that many paths in a circuit have common subpaths. RESIST sensitizes those subpaths only once, TedUCing the number of value assignments dun'ng path sensitization(More)
A globally disseminated strain of M1T1 group A Streptococcus (GAS) has been associated with severe infections in humans including necrotizing fasciitis and toxic shock syndrome. Recent clinicoepidemiologic data showed a striking inverse relationship between disease severity and the degree to which M1T1 GAS express the streptococcal cysteine protease, SpeB.(More)
After in vitro exposure to lipopolysaccharide (LPS) or muramyl dipeptide (MDP), cultured resident mouse peritoneal macrophages were primed to display enhanced generation of superoxide anion (O2-) in response to stimulation by phorbol myristate acetate (PMA) or opsonized zymosan. Priming with LPS (1 microgram/ml) produced a sevenfold enhancement of(More)
This paper reports on the initial analysis of protein expression in the mouse cerebellum with the proteomics approach. Proteins from cerebellar tissue homogenates were separated by two-dimensional gel electrophoresis, and the proteins were stained with colloidal Coomassie Blue to produce a high-resolution map of the cerebellum proteome. Selected proteins(More)
Muramyl peptides are fragments of peptidoglycan from the cell walls of bacteria. Because of their unique chemistry, the immune system recognizes that muramyl peptides are products of bacteria, and it responds by becoming activated to resist infection. This resistance to infection is nonspecific, and extends to unrelated species of bacteria, fungi, and(More)
BACKGROUND Monocytes can be primed in vitro by lipopolysaccharide (LPS) for release of cytokines, for enhanced killing of cancer cells, and for enhanced release of microbicidal oxygen radicals like superoxide and peroxide. We investigated the proteins involved in regulating priming, using 2D gel proteomics. RESULTS Monocytes from 4 normal donors were(More)
The adjuvant muramyl dipeptide (MDP) has been shown to affect a number of macrophage functions in vitro. We studied the effect of subcutaneous injection of MDP into mice. Cultured peritoneal macrophages from treated mice displayed increased spreading, total cell protein, and specific activity of beta-glucosaminidase a constituent of macrophage lysosomes,(More)
Three alternative designs of the European Spallation Source (ESS) high energy linac are described. The most promising ones are either a normalconducting (nc) coupled cavity linac (CCL) up to final energy or a change at 407 MeV to only one group of 6 cell superconducting (sc) elliptical cavities. Fully 3d Monte Carlo simulations are presented for both(More)
This study examined the access and organization of goal-derived categories in semantic memory with a group of chronic traumatic brain injured TBI adults and a group of age and gender-matched neurologically-intact controls. Goal-derived categories are developed by individuals for use in specialized contexts to achieve a goal, such as 'things to take on a(More)
