Abstract: A wafer grinding parameter optimization method and an electronic device are provided. The method includes the following. A natural frequency of a grinding wheel spindle of wafer processing equipment is obtained, and a grinding stability lobe diagram is generated accordingly. A grinding speed is selected based on a speed range of the grinding wheel spindle. Multiple grinding parameter combinations are determined based on the grinding speed. Multiple grinding simulation result combinations corresponding to the grinding parameter combinations are generated. A specific grinding parameter combination is selected based on each of the grinding simulation result combinations, and the wafer processing equipment is set accordingly.

Abstract: A multi-view human action recognition method based on hypergraph learning, comprising acquiring video data from P views, and further comprising the following steps: pre-processing the video data; constructing spatial hypergraphs based on joint information; constructing temporal hypergraphs based on the joint information; performing feature learning of the spatial hypergraphs and the temporal hypergraphs using hypergraph neural networks; and extracting higher order information represented by the hypergraphs, and performing action recognition of human actions.

Abstract: A composition containing a docetaxel albumin nanoparticle. The composition contains docetaxel and an acid-denatured albumin, wherein the acid-denatured albumin is obtained by means of adding an acid to human serum albumin to adjust the pH value. The composition can be prepared into an injection or a freeze-dried powder injection. A composition with satisfactory physical and chemical stability is obtained by means of controlling the content of sodium octanoate in human serum albumin, preferably in an acid denaturation condition.

Abstract: An electronic device is disclosed. The electronic device includes a substrate, a plurality of color filters disposed on the substrate, an optical film disposed on the plurality of color filter, and a defect disposed between the substrate and the optical film. The optical film has a first base, a protective layer on the first base, and a second base between the first base and the protective layer and having a first processed area. In a top view of the electronic device, the first processed area corresponds to the defect and at least partially overlaps at least two color filters.

Abstract: Technologies for a flexible three-dimensional power plane in a chassis are disclosed. In one embodiment, a flexible ribbon cable is laid along a circuit board tray. The flexible ribbon cable is secured to the tray using power bosses. The power bosses connect to one or more conductors on the ribbon cable. When the circuit board is mounted on the circuit board tray, the power bosses extend through holes in the circuit board and mate with power clips on the surface of the circuit board tray. The ribbon cable, power bosses, and power clips can distribute power to various locations on the circuit board, without requiring large traces that take up space on the circuit board.

Abstract: A cleaning robot includes a housing, a dust box and a dust extraction duct. The housing is enclosed to form a mounting chamber and is provided with a dust outlet. The dust box is arranged in the mounting chamber and configured to collect dust, and the dust box is provided with a dust collection port and a dust extraction port. The dust collection port and the dust extraction port are respectively disposed on two sides of a centerline of the dust box. One end of the dust extraction duct communicates with the dust extraction port, and the other end of the dust extraction duct is connected to the dust outlet of the housing.

Abstract: Disclosed is a text classification method and a text classification device. The text classification method includes: receiving text data (S1), the text data comprising one or more text semantic units; replacing the text semantic unit with a corresponding text keyword (S2), based on a correspondence between text semantic elements and text keywords; extracting, with a semantic model, a semantic feature of the text keyword (S3); and classifying, with a classification model, the text keyword at least based on the semantic feature, as a classification result of the text data (S4).

Abstract: A wet cleaning process is provided. The wet cleaning process includes at least one first rinse process and a second rinse step. The first rinse step includes rinsing a substrate using deionized water containing CO2, and then draining the water containing CO2 to expose the substrate in an atmosphere of CO2. The second rinse step includes rinsing the substrate using deionized water containing CO2.

Abstract: A tire pressure detecting/warning apparatus includes a main body mounted to a tire valve for introducing air pressure in the tire. The main body includes a first air passage and a second air passage. A first reed is mounted on the first air passage and is deformed to be in electrical contact with a first contact when the tire pressure is higher than a pre-determined relatively higher value of a safety range. A second reed is mounted on the second air passage and is deformed to be disengaged from a second contact when the tire pressure is lower than a pre-determined relatively lower value of the safety range. The tire pressure is too high if the first reed is in contact with the first contact, and the tire pressure is too low if the second reed is disengaged from the second contact. In either case, a radio- transmitting device sends a signal to a receiver in the vehicle, and a siren is activated to give a warning by sound or lamp that the pressure is too high or too low.
