Abstract: A displaying base plate and a manufacturing method thereof, and a displaying device. The displaying base plate includes an opening area and an isolation area surrounding the opening area, the isolation area includes: a first flexible substrate and at least one isolation slot provided on one side of the first flexible substrate, and the isolation slot is formed by a first inorganic film layer, an organic film layer and a second inorganic film layer that are disposed in stack; the first inorganic film layer is disposed close to the first flexible substrate, and the first inorganic film layer has a first surface facing the opening area; the organic film layer is provided on one side of the first inorganic film layer that is away from the first flexible substrate, and the organic film layer has a second surface facing the opening area.

Abstract: Techniques and tools for encoding enhancement layer video with quantization that varies spatially and/or between color channels are presented, along with corresponding decoding techniques and tools. For example, an encoding tool determines whether quantization varies spatially over a picture, and the tool also determines whether quantization varies between color channels in the picture. The tool signals quantization parameters for macroblocks in the picture in an encoded bit stream. In some implementations, to signal the quantization parameters, the tool predicts the quantization parameters, and the quantization parameters are signaled with reference to the predicted quantization parameters. A decoding tool receives the encoded bit stream, predicts the quantization parameters, and uses the signaled information to determine the quantization parameters for the macroblocks of the enhancement layer video. The decoding tool performs inverse quantization that can vary spatially and/or between color channels.

Abstract: An Android penetration method and device for implementing silent installation based on accessibility services. The method includes: acquiring a second target application by adding a load program to a first target application and adding penetration permissions using an Android decompilation technology; and implementing silent installation of the second target application using an accessibility service technology.

Abstract: Techniques described enable answering a natural language question using machine learning-based methods to gather and analyze evidence from web searches. A received natural language question is analyzed to extract query units and to determine a question type, answer type, and/or lexical answer type using rules-based heuristics and/or machine learning trained classifiers. Query generation templates are employed to generate a plurality of ranked queries to be used to gather evidence to determine the answer to the natural language question. Candidate answers are extracted from the results based on the answer type and/or lexical answer type, and ranked using a ranker previously trained offline. Confidence levels are calculated for the candidate answers and top answer(s) may be provided to the user if the confidence levels of the top answer(s) surpass a threshold.
