Abstract: A DC socket includes: a base including a receiving groove, and a pair of fixed attracting members and a pair of electrode socket contacts disposed in the receiving groove; a first connecting member, an end of the first connecting member being electrically connected to one electrode socket contact, and the other end of the first connecting member being provided with a moving contact point; a moving member adapted to be pressed or released by a pin to move along a moving direction; a mating member movably connected to the moving member and adapted to move along the moving direction and coupled to the first connecting member; and a movable attracting member disposed on the mating member and located between the pair of fixed attracting members. The movable attracting member can move towards a corresponding fixed attracting member upon being adjacent to the corresponding fixed attracting member.

Abstract: Embodiments of the disclosure provide a DC socket. The DC socket includes: a bracket including a pair of first through holes; a pair of socket contacts each disposed at the corresponding first through hole; a protective shutter slidable relative to the bracket between a first position and a second position along a first direction, where the protective shutter includes a pair of driving surfaces disposed at an angle to each other, one driving surface can be driven by the positive pin, and the other driving surface can be driven by the negative pin, where the first direction is arranged at an angle with respect to a width direction of the positive pin and a width direction of the negative pin, to enable the protective shutter to slide obliquely; and a covering member covering the protective shutter and the bracket and including a pair of second through holes.

Abstract: A DC socket includes: a bracket including a first through hole and a pair of second through holes; three socket contacts including a ground socket contact disposed at the first through hole and a pair of electrode socket contacts each disposed at the corresponding second through hole; and a protective shutter supported by the bracket and slidable between a first position and a second position along a first direction. The protective shutter includes a driving surface that is adapted to be driven by a ground pin, and the first direction is arranged at an angle with respect to width directions of a positive and negative pins, to enable the protective shutter to slide obliquely. When the protective shutter is in the first position, the driving surface is aligned with the first through hole to block through holes. When the protective shutter is in the second position, the through holes are exposed.

Abstract: A receiver circuit without baseline wandering is shown, in which the paired alternating (AC) coupling circuit and conductive (DC) coupling circuit are connected in parallel. The feedback voltages obtained from the DC coupling circuits are controlled to track the desired common mode voltage. In this manner, the common mode voltage between the equalization nodes is stable.

Abstract: The freshness of one or more terms in a documentation, indicative of a currency of the one or more terms is computed. Each term includes one or more constituent words, and the terms are visually marked as current or out-of-date based on the computed freshness. Upon marking a term as out-of-date, a latest term for the out-of-date term is retrieved or a most possible latest term for the out-of-date term is predicted.

Abstract: The present disclosure is generally related to compositions and methods for constructing and/or obtaining B. licheniformis cells (e.g., protein production hosts) comprising enhanced protein production capabilities. Thus, certain embodiments are related to genetically modified Bacillus licheniformis strains derived from parental B. licheniformis strains producing increased amounts of one or more proteins of interest.

At least two refrigeration liquid pumps are arranged in the second refrigeration liquid supply path for bearing lubrication, the at least two refrigeration liquid pumps are arranged in parallel, and the at least two refrigeration liquid pumps include a main refrigeration liquid pump and at least one standby refrigeration liquid pump.

Abstract: Provided are a bispecific antibody, an encoding nucleic acid thereof, an AAV virus vector containing the nucleic acid, and a virus particle. Further provided is a pharmaceutical composition containing the bispecific antibody, the encoding nucleic acid, the AAV virus vector, or the virus particle. The bispecific antibody comprises binding domains specific to VEGF-A and ANG-2, and can be used for treating wet age-related macular degeneration or diabetic macular edema of a subject.

Abstract: Provided are a compound of formula I, a stereoisomer or a pharmaceutically acceptable salt thereof, a pharmaceutical composition including the compound, a preparation method for the compound and a use thereof in preparation of drugs for treating LSD1-related diseases.

Abstract: Methods of using thermostable serine proteases are described herein.

Abstract: A wireless microphone system utilizes an antenna structure that supports dual frequency bands. With some embodiments, the wireless microphone system comprises a first apparatus (for example, a wireless transmitter) and an attached second apparatus (for example, an attached microphone), where the chassis of the first apparatus and the housing of the second apparatus support the antenna structure through an electrical connector (for example, through an outer shell of a Cannon (XLR) connector) between the two apparatuses. The chassis and the housing may support first and second halves of a dipole antenna, respectively. The first apparatus supports first and second electrical circuits that are operational within a first and second frequency band, respectively, and that connect to first and second input ports of a combining circuit (for example, a diplexer filter). The output port of the combining circuit connects to the housing through the electrical connector.

Abstract: Certain embodiments of the disclosure are related to recombinant Bacillus strains comprising enhanced protein productivity phenotypes, compositions and methods for constructing such recombinant Bacillus cells, and the like. The recombinant Bacillus strains described herein are particularly useful for the enhanced production of proteins of interest when grown/cultivated/fermented under suitable conditions.

Abstract: A needle aid device comprises an outer shell; an inner shell located in the outer shell and comprising an upper portion and a lower portion, a trigger shell passage penetrating through the upper portion and the lower portion being formed in the inner shell, and an inner diameter of the lower portion being greater than that of the upper portion; and a trigger module capable of moving in the trigger shell passage and used for clamping or releasing an emitter mechanism; wherein, in an initial state, the trigger module is locked on the upper portion; and when unlocked, the trigger module drives the emitter mechanism to move downward until the emitter mechanism is separated from the trigger module.
