Response mechanism of impact load based on marine shafting-oil film-stern structure system

Zhongguo Jianchuan Yanjiu, 2017
The anti-impact ability of shafting directly affects the stability and security of a ship's power transmission, and it cannot be ignored that large-scale effects on ships have an influence on the interaction intensity of the impact load.

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 ...
