Abstract: The disclosure provides a method for monitoring a short-term voltage stability of a power system. The method includes: obtaining a topology and time series of a current power system; inputting the topology and the time series of the current power system into a trained spatial-temporal graph network model, the trained spatial-temporal graph network model being obtained by classification learning on a spatial-temporal graph network model based on a simulation sample dataset; outputting a status of the short-term voltage stability of the power system; and sending an alarm signal in response to outputting an unstable status of the short-term voltage stability of the power system.

Abstract: Provided herein are methods of generating T cells, e.g., cytotoxic T lymphocytes starting from peripheral blood mononuclear cells without a separate step of generating and isolating antigen-presenting cells, and with a single round of antigen stimulation.

Abstract: Provided is a low-molecular-weight holothurian glycosarninoglycan, with the constituent units thereof being a glucuronic acid group, an N-acetaminogalactose group and a fucose group, and a sulfate ester group or acetyl ester group thereof. Glucuronic acid and N-acetaminogalactose are interconnected via ?(1-3) and ?(1-4) glucosidic bonds to form a backbone of a disaccharide repeating structural unit, and a fucose group is connected to the backbone as a side chain. On a molar ratio basis, the ratio of the glucuronic acid group:the N-acetaminogalactose group:the fucose group is 1:(0.8-1.2):(0.6-1.2). In the structure of the low-molecular-weight holothurian glycosaminoglycan, 10-30% of glucuronic acid groups are modified, on the 2-position, with a sulfate ester group, and the rest are hydroxyl groups; and a proportion of 10-30% of fucose groups is modified, on the 2-position, with an acetyl ester group, and the rest are hydroxyl or sulfate ester groups.

Abstract: The present invention provides a buoyant system and method for a hydrocarbon offshore floating platform to be coupled and decoupled from a subsea buoyant extension with risers slidably coupled thereto. The buoyant system can allow rigid risers to be coupled and decoupled and alternatively move between a first elevation below the offshore floating platform, such as at the buoyant extension, and a higher second elevation at the offshore floating platform independent of a spool piece, arch support, and flexible joint for the risers. The buoyant system can reduce riser stress by reducing bending required for the riser to form a catenary or other curved shape even as a rigid riser.
