Var. monghlicus (Bge) Hsiao, Ranunculus ternatus Thunb., Sophora flavescens Alt. and Salvia miltiorrhiza Bge. The composition and extract thereof may be used for treating liver injury, hepatitis, hepatic fibrosis, hepatic cirrhosis or liver cancer, and they may also be used as a vaccine adjuvant or an immunomodulator.

Abstract: A summary obtaining method includes obtaining a target document from which a summary is to be obtained; dividing the target document into sentences and dividing each sentence into words; and obtaining a classifier constructed based on a long short-term memory (LSTM) model. The classifier comprises a word-level LSTM layer configured to determine a vector of each sentence according to the words in each sentence, and a sentence-level LSTM layer configured to determine a vector of the target document according to the vector of each sentence. The method further includes determining, by using the classifier, a probability that each sentence is a summary sentence, according to the vector of the target document and a vector of the sentence; and determining a sentence with the probability satisfying a predetermined condition for a summary sentence, as a summary sentence of the target document, and forming the summary according to the summary sentence.

Abstract: A flexible dual mode battery charger that charges a battery in two different modes, depending on the difference between the adapter voltage and the battery voltage, with a smooth transition between these two modes and the charging current remains relatively constant during the transition is provided in this application. At a lower battery level, the dual mode battery charger charges the battery as a LDO charger and when battery voltage is very close to the adapter voltage, the charger migrates its operating mode from the LDO mode to the boost mode and charges the battery as a boost charger. This flexible battery charger uses one common control circuit for controlling the operations of the LDO charger and the boost charger. The switching operation from one operation mode to other operation mode is smooth.
