Abstract: Provided are a lithium secondary battery electrolyte composition which may effectively suppress a thermal runaway phenomenon, and a lithium secondary battery having excellent electrical properties, life characteristics, and safety by applying the electrolyte composition.

Abstract: Variable resistance elements and semiconductor devices including the variable resistance elements are disclosed. In some implementations, a variable resistance element may include a variable resistance element may include a free layer having a variable magnetization direction that switches between different magnetization directions upon application of a magnetic field, a pinned layer having a fixed magnetization direction, and a tunnel barrier layer interposed between the free layer and the pinned layer and including a metal chalcogenide having a cubic crystal structure.

Abstract: Provided is an apparatus for online action detection, the apparatus including a feature extraction unit configured to extract a chunk-level feature of a video chunk sequence of a streaming video, a filtering unit configured to perform filtering on the chunk-level feature, and an action classification unit configured to classify an action class using the filtered chunk-level feature.

Abstract: A deburring tool includes: a body; and a cutting unit provided on an end portion of the body and including a blade part, where a first channel is provided inside the body, and when a fluid supplied from outside of the deburring tool through the first channel is injected into the cutting unit and presses the cutting unit, the cutting unit moves and a degree to which the blade part protrudes outwardly increases.
