Abstract: The present invention relates to antibody-drug conjugates (ADCs) wherein a plurality of active agents are conjugated to an antibody through at least one branched linker. The branched linker may comprise a branching unit, and two active agents are coupled to the branching unit through a secondary linker and the branching unit is coupled to the antibody by a primary linker. The active agents may be the same or different. In certain such embodiments, two or more such branched linkers are conjugated to the antibody, e.g., 2-4 branched linkers, which may each be coupled to a different C-terminal cysteine of a heavy or light chain of the antibody. The branched linker may comprise one active agent coupled to the branching unit by a first branch and a second branch that comprises a polyethylene glycol moiety coupled to the branching unit. In certain such embodiments, two or more such branched linkers are conjugated to the antibody, e.g.

Abstract: Disclosed is a display device having a thin film transistor substrate, which may prevent afterimage and flicker defects by reducing the non-uniformity of an electric field. In the thin film transistor substrate, a pixel electrode includes a transparent edge electrode and a transparent inner electrode, which are spaced apart from each other with a first slit having a first width interposed therebetween, and a common electrode is exposed from the other-side end of the transparent edge electrode by a second width, which is smaller than the first width, in the width direction of a data line. As such, an inner area and an edge area in each sub pixel have uniform electric field distribution.

Abstract: An electronic device is provided. The electronic device includes a memory configured to store a high-speed video captured with a first number of frames per second and a processor configured to be electrically connected with the memory. The processor is configured to detect an amount of image variation based on at least one of the first number of frames and generate a slow motion interval, a playback time of which is extended, by dividing or sampling the first number of frames into a second number of frames which are less than the first number of frames with respect to a video interval having an amount of image variation which meets a specified condition.

Abstract: A method of erasing a power calibration area (PCA) for determining optimum power, including applying a command for recording data, detecting a non-recorded PCA area for performing optimum power control (OPC), and when all the PCA area is used and no non-recorded PCA area is detected, performing erasing of the PCA area at least twice. Accordingly, since the PCA area is erased at least twice, reliability of the optimum recording power determined by performing the OPC is much improved.
