Abstract: The present invention provides an alginic acid-based injectable hydrogel system for labeling an accurate position of a disease lesion and effectively delivering a drug to a target region. The formulation of the present invention can make it easy to locally inject a contrast agent and a drug into a target region while controlling the release rate of the contrast agent or the drug, with the formation of the hydrogel in the injected region. Through the advantages, the labeled position can be accurately determined from images, thereby enhancing the precision of surgical operation, with a minimal incision formed therefor. In addition, when used, the alginic acid-based injectable hydrogel system allows the effective local delivery of a drug to a target region while increasing the long-acting effect of the drug.

Abstract: Described is a sliding device allowing a user to switch between an electric sliding mode and a manual sliding mode as needed and including a guide rail module, a sliding rail slidably coupled to the guide rail module, a rail driving module coupled to the sliding rail and configured to move the sliding rail along the guide rail module by driving of a motor, and a sliding mode switching module configured to switch an operation mode of the sliding rail from an electric sliding mode to a manual sliding mode by blocking a driving force of the rail driving module from being transmitted to the sliding rail. The sliding device may be used for sliding a storage box for a vehicle.

Abstract: Mechanisms are provided for intrusion detection based on regular expression matching. The mechanisms partition a regular expression (RegEx) rule set into a plurality of different partitions and distributes the plurality of different partitions to a plurality of different edge computing devices associated with a protected network of computing resources. The mechanisms route data packets of an incoming data stream to the plurality of edge computing devices, each of which processes the data packets to determine whether the data packets match RegEx rules in a partition distributed to the edge computing device. A determination is made as to whether the incoming data stream represents an intrusion based on a combination of results of the processing of the data packets by the plurality of edge computing devices.

Abstract: Disclosed are, inter alia, a positive electrode slurry containing reduced content of a binder, a method of preparing the positive electrode slurry, a positive electrode made from the slurry and a lithium secondary battery including the positive electrode.

Abstract: Provided are an apparatus and method of generating a tracking error signal, and an optical information storage system including the apparatus. The apparatus includes a bias signal generator for generating a bias signal for canceling a direct current (DC) offset of a push-pull signal using a tracking control signal generated by the tracking controller. Accordingly, an offset generated in a tracking error signal may be canceled or otherwise reduced using the bias single instead of using an additional side beam.
