Abstract: A turnout structure, which includes at least one turnout. The at least one turnout includes a fixed beam set. The fixed beam set includes a first side beam and a second side beam. The at least one turnout further includes a movable beam set. The movable beam set is disposed between the first side beam and the second side beam to define two switchable driving channels. A top surface of the movable beam set is configured as a first locomotion surface for locomotion wheels of a railway vehicle. The movable beam set includes a rotating beam and a moving beam. A first end of the rotating beam includes a rotating center. The rotating beam is configured to rotate around the rotating center, and the moving beam is connected to a second end of the rotating beam and configured to move along a path.

Abstract: A turnout structure includes at least one turnout. The at least one turnout includes: a fixed beam set including a first side beam and a second side beam, and at least two movable beam sets disposed between the first side beam and the second side beam to define at least three switchable traveling pathways. Top surfaces of the at least two movable beam sets are configured to be a first traveling surfaces for traveling wheels of a rail vehicle to travel. Each of the at least two movable beam sets includes a rotating beam and a moving beam. A rotating center is located on a first end of the rotating beam, the rotating beam is configured to rotate around the rotating center, and the moving beam is connected to a second end of the rotating beam and configured to move along a path.

Abstract: A baculovirus vector and a use thereof in the preparation of a recombinant adeno-associated virus (rAAV) in an insect cell are provided. The baculovirus vector includes an exogenous gene expression cassette and a stable sequence. The stable sequence is located at a site 5 kb or less from the exogenous gene expression cassette, and the stable sequence is a conserved noncoding element (CNE) sequence or a nucleocapsid assembly-essential element (NAE) sequence. When an insect cell is infected with a recombinant baculovirus (rBV) constructed in this way, after multiple continuous passages, production levels of the rBV and the rAAV still remain relatively stable.

Abstract: An expression cassette containing overlapping open reading frames and an application thereof are provided. The overlapping open reading frames are overlapping open reading frames of a first ORF and a second ORF and include in sequence from a 5? end to a 3? end: a first promoter at least used to drive gene transcription of the first ORF; a 5? part of a gene of the first ORF; an intron; and a 3? part of a gene of the second ORF, the intron including a second promoter used only to drive gene transcription of the second ORF. By arranging two promoters in a single expression cassette in the disclosure, the two promoters are used to drive the expression of proteins of the overlapping reading frames and regulate the relative expression time and expression intensity of different proteins.

Abstract: A method for detecting a state of an energy storage device (e.g. lithium-ion battery) is provided, which includes acquiring at least one of a change signal of a temperature or a change signal of a pressure inside the energy storage device, and determining the state of the energy storage device based thereon. The method may further include triggering a warning when the state of the energy storage device meets a preset condition, such as when the energy storage device is determined to be in an irreversible state, an internal short circuit state, a safety valve opening state, or a thermal runaway state. A detection device implementing the detection method is also provided, which comprises a sensing module and an analyzing module. The sensing module is arranged at an interior position of the energy storage device, and can include an optical sensor and/or an electrical sensor.

Abstract: An inner guide rail switch and a rail transit system having same. The inner guide rail switch includes a fixed beam assembly and a movable beam assembly. Four passageways are defined by the fixed beam assembly. The movable beam assembly includes six movable beams. The four passageways are switched through combined movement of the six movable beams.

Abstract: An inner guide rail switch (100) and a rail transit system (1000) having same. The inner guide rail switch (100) includes a fixed beam assembly (1) and a movable beam assembly (2). Four passageways are defined by the fixed beam assembly (1). The movable beam assembly (2) includes six movable beams. The four passageways are switched through combined movement of the six movable beams.
