Mutations in the chromatin remodeling gene ARID1A have recently been identified in the majority of ovarian clear cell carcinomas (OCCCs). To determine the prevalence of mutations in other tumor types, we evaluated 759 malignant neoplasms including those of the pancreas, breast, colon, stomach, lung, prostate, brain, and blood (leukemias). We identified(More)
BACKGROUND Traditional imaging techniques for the localization and monitoring of bacterial infections, although reasonably sensitive, suffer from a lack of specificity. This is particularly true for musculoskeletal infections. Bacteria possess a thymidine kinase (TK) whose substrate specificity is distinct from that of the major human TK. The substrate(More)
Automated test generation Low false positives High code-coverage Challenges and solutions Tools analysis Prospects a b s t r a c t Dynamic symbolic execution for automated test generation consists of instrumenting and running a program while collecting path constraint on inputs from predicates encountered in branch instructions, and of deriving new inputs(More)
This study investigated contaminant transport and evaluated the ventilation performance in a single-bed inpatient room. The study performed comparative experimental analysis on the distributions of respiratory contaminants breathed out and coughed out by a patient in a full-scale chamber, which simulated a single-bed inpatient room. The contaminant exhaled(More)
Keywords: Proactive P2P worm Repair-and-patch approach Benign worm Difference equations Fast quarantine Low consumption of bandwidth resources a b s t r a c t P2P worms pose a serious threat to Internet infrastructure and terminal users because of their overwhelming propagation speed. Manual reactions fall behind the fast propagation of P2P worms. Current(More)
