Abstract: Disclosed are a method for adjusting a signal of a display panel, a time controller integrated circuit, a display panel, and a storage medium. The method includes: converting first data into a first data voltage signal using a first data voltage, in response to a set condition being reached, sending the first data voltage signal to a chip on film integrated circuit, the chip on film integrated circuit identifies the first data voltage signal to obtain a second data; acquiring the second data from the chip on film integrated circuit, determining that the chip on film integrated circuit fails to identify the first data in response to the second data being different from the first data; and adjusting the first data voltage until a second data voltage signal converted from the first data using a second data voltage after adjustment being successfully identified by the chip on film integrated circuit.

Abstract: A method for calculating a velocity model for a subsurface of the earth. The method includes receiving (200) measured seismic data d; calculating (204) predicted seismic data p; selecting (206) a matching filter w that when applied to one of the measured seismic data d or the predicted seismic data p reproduces the other one of the measured seismic data d or the predicted seismic data p; selecting (208) a misfit function J that calculates (1) a distance between the matching filter w and a Dirac Delta function or (2) a travel time shift associated with the measured seismic data; and calculating (218) a new velocity model using the misfit function J, the measured seismic data d, and the predicted seismic data p. The measured seismic data d includes wavefields generated by a seismic source and the wavefields propagate through the subsurface where they are attenuated and reflected, and the attenuated and reflected wavefields are recorded by plural seismic receivers.

Abstract: A method for preparing a combination adjuvant is based on carboxyl modified aluminum oxyhydroxide nanoparticles. The preparation method uses carboxylated hydroxyl oxide nanoparticles as a carrier, but is not limited to the role of a carrier. The carboxylated hydroxyl oxide nanoparticles are combined with a novel CpG-ODN adjuvant, such that the half-life period of a CpG adjuvant is prolonged. The combination of adjuvants shows a synergistic effect, such that the Th2 type immune stimulation ability is enhanced, and the possibility of Th1 type immunity is also given to the adjuvant.

Abstract: A three-dimensional (3D) seismic data set is divided into a plurality of 3D source wavefield subsets, each 3D source wavefield subset is stored in an array element of an array. For each array element, the associated 3D source wavefield is decomposed into a smaller data unit; data boundaries of the smaller data units are randomly shifted; a folding operation and a sample operator is applied to the smaller data units to keep the smaller data units from overlapping; the folded smaller data units are smoothed to generate smoothed data; a quantization operation is performed on the smoothed data to produce quantized data; and the quantized data is compression encoded to generate compressed data. The compressed data associated with each array element is decompressed to generate a 3D seismic output image.

Abstract: The present disclosure discloses a novel biochip substrate, a preparation method and an application thereof. The surface of the novel biochip substrate contains active vinyl sulfone groups. The preparation method involves a one-step reaction of a compound containing vinyl sulfone groups on both ends with a silicon-hydroxyl group on the surface of a silicon-based biochip substrate material under catalytic conditions, to prepare the biochip substrate. The application immobilizes biomacromolecules by conducting Michael addition of amino or sulfydryl group in biomacromolecules and the vinyl sulfone group on the surface of the biochip substrate, realizing biological functionalization thereof. The biochip substrate has high-density active vinyl sulfone groups, which can be used for immobilization of various biomolecules with mild fixation conditions and simple operation.
