Improving static techniques for the analysis of voltage stability

International Journal of Electrical Power & Energy Systems, 2011
The currently available dynamic techniques for the analysis of voltage stability are truly accurate but also expensive in terms of computation time. With the objective of overcoming such a disadvantage, several static techniques have been developed. Unlike conventional dynamic techniques, they share the advantage of drastically reducing computation ...

Retrospective Analysis of Donor Lymphocyte Infusions in Pediatric Patients With Mixed Chimerism After Hematopoietic Stem Cell Transplantation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...
