A coaxial film capacitor with a novel structure to enhance its flashover performance.

As one of the key components of an electromagnetic pulse simulator, the peaking capacitor is coaxially constructed with a laminate structure utilizing alternative thin metal rings and polymer film dielectrics, which is designed as a part of the antenna. This paper presents a coaxial film capacitor with a novel structure to improve its flashover performance. First, the relationship between the capacitance and the capacitor's structural parameters are deduced, and a theoretical basis of lengthening the polymer film dielectrics to enhance the flashover performance is discussed.

Epitope-based matching for HLA-alloimmunized platelet refractoriness in patients with hematologic diseases.

Background: For HLA-alloimmunized patients, platelet (PLT) concentrations are provided either at matched HLA-A and HLA-B loci or by serologic cross-reactivity groups (CREG) matching strategy. However, this method has some limitations.

Study Design And Methods: In this study, the epitope-based matching (EBM) method was evaluated for selecting proper HLA-typed PLTs for patients with PLT transfusion refractoriness.
