Abstract: A meeting robot method and system is provided. In one embodiment, a meeting substitute system includes processing circuitry configured to cause the meeting substitute system to obtain information related to a meeting request, the information associated with a teleconference meeting and the information including a date and a time for the teleconference meeting; as a result of a trigger, automatically: join the teleconference meeting at the date and the time; and during the joined teleconference meeting, capturing a set of meeting data for the teleconference meeting, the captured set of meeting data comprising at least one of a video recording and an audio recording of the teleconference meeting and a speech-to-text translation; and generate a meeting summary based at least in part on the captured set of meeting data for the teleconference meeting.

Abstract: The present invention provides a huperzine B crystal and a preparation thereof. Specifically, the present invention provides a crystal form A of the huperzine B crystal. An X-ray diffraction pattern of the crystal form A has the following 2? angular characteristic absorption peak: 9.56±0.2, 13.90±0.2, 14.88±0.2, 16.00±0.2, 25.39±0.2, and 28.78±0.2.

Abstract: The display substrate comprises a display area and a peripheral area surrounding the display area. The display substrate comprises: a substrate, a first and second conductive layers located on the substrate and sequentially arranged in the direction away from the substrate, and a first organic insulating layer located between the first and second conductive layers. The first conductive layer comprises a plurality of first metal wires extending in a first direction. The second conductive layer comprises a plurality of second metal wires extending in the first direction. In the peripheral area, the first organic insulating layer is divided, and the edge of the first organic insulating layer extends in a second direction and forms a first step. The second direction intersects with the first direction. The first step comprises at least one protruding structure and at least one recess structure located between the adjacent second metal wires.

Abstract: The present invention relates to novel phalloidin derivatives and their fluorescent dye conjugates. These new compounds may be used in studies of actin dynamics in living systems. The present invention also relates to methods for preparing such compounds. The synthesis routes combine solid-phase and solution phase peptide synthesis, and has great advantage for efficient preparation of a diverse library of the phalloidin derivatives, especially for the synthesis of phalloidin.
