Experimental Modeling of Forward Recovery Characteristics of IGBT for DC Circuit Breaker
DC circuit breaker is the main means to clear the faults in VSC-HVDC power grid. Before action of the hybrid DC circuit breaker, the IGBT in the transfer branch is in a state of zero voltage and zero current.

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 ...

Over Voltage and Under Voltage Protection System Using IoT
Abstract Sudden fluctuation in voltage may cause a serious problem in industries and home appliances. These fluctuations may significantly impact the power quality as well as the reliability of other voltage controlling devices. However, this paper discussed about designing for under voltage and over voltage protection to protect and ...

ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...

ABSTRACT Background Maintenance hemodialysis (MHD) patients frequently suffer from frailty, characterized by reduced physical function and poor prognosis. Myokines, such as myonectin, secreted by muscle, are emerging regulators of systemic health. This study investigated the relationship between serum myonectin, adipokines (adiponectin, omentin), and ...
