Abstract: The present disclosure provides a combined vaccine against human respiratory syncytial virus (RSV) infection and a method thereof for inducing immune response. The combined vaccine includes; a first composition including an immunologically effective dosage of a replication-deficient human adenovirus type 26 vector contains a nucleotide encoding an antigenic protein of RSV and a pharmaceutically acceptable vector; and a second composition including an immunologically effective dosage of a replication-deficient chimpanzee adenovirus type 63 vector contains a nucleotide encoding an antigenic protein of RSV and a pharmaceutically acceptable vector. The first composition is a primary immunization composition and the second composition is a booster immunization composition, or vice versa. In the present disclosure, the combined vaccine is used for inducing a protective immunity against RSV infection, and a method is provided for generating the protective immunity against RSV infection.

Abstract: A multi-phase buck converter circuit is provided, including a power supply, a plurality of phase buck circuits, each phase buck circuit including an input terminal, an output terminal, and a second input terminal, with input terminals of the plurality coupled to the power supply, a plurality of inductors coupled to the output terminals of the plurality of phase buck circuits, the plurality of inductors providing an output voltage at an output of the multi-phase buck converter circuit, a detection controller coupled to the output terminals of the plurality of phase buck circuits, the detection controller configured to detect a fault in the plurality of phase buck circuits, and a drive circuit coupled to the detection controller and coupled to each second input terminal of the plurality of phase buck circuits. The drive circuit is configured to detect a faulty phase buck circuit and stop driving the faulty phase buck circuit.
