Abstract: Disclosed is a pyridazinone compound represented by Formula (I), or a pharmaceutically acceptable salt, prodrug, hydrate, solvate, polymorph, stereoisomer, or isotopic variant thereof. The compound can be used for preparation of medicinal products for treatment and/or prophylaxis of a disease or condition associated with thyroid hormone abnormalities. The compound has higher selectivity to TH?, better pharmacokinetic parameters, desired stability, and higher agonistic activity toward TH?.

Abstract: A display panel includes a display region and a photoelectric sensing region which includes a light transmitting region and a frame region surrounding the light transmitting region; the frame region includes a first region surrounding the light transmitting region, a second region on a side of the first region away from the light transmitting region and surrounding the first region, and a third region between the second region and the display region. The spacers are in an array and in the display region but not in the light transmitting region. A plurality of first support pillars are in the first region, arranged around the light transmitting region, and spaced from each other. A plurality of second support pillars are in the second region, around the second region, and spaced from each other. A plurality of third support pillars are in the third region in an array.

Abstract: A method for assessing test adequacy of deep neural networks based on element decomposition is provided. The network testing is divided into black box testing and white box testing, of which key elements are decomposed and defined. Network parameters including a weight matrix and a bias vector are extracted. Importance values of neurons in individual layers of the deep neural network are calculated and clustered, and an importance value hot map of neurons in each layer is generated based on clustering results. Mutation testing, and index calculation and evaluation are performed.

Abstract: Provided is a flip chip space pixel arrangement structure, a pixel multiplexing method and system, an apparatus and a storage medium. The pixel multiplexing method includes: equidistantly dividing, in rows and columns, an LED display screen into a plurality of first element sets and a plurality of second element sets; on the basis of a pixel acquisition algorithm, sampling a single frame of original image having high resolution into seven basic images having low resolution; on the basis of a determination strategy, formulating display orders of the basic images, the single frame of original image corresponding to three display orders, and each of the display orders corresponding to one or more of the basic images; and on the basis of the display orders, sequentially displaying each of the basic images in a single frame duration, to complete sub-pixel reconstruction of the flip chip space pixel arrangement structure.

Abstract: Disclosed are an LED light emitting pixel arrangement structure and a display panel device. The pixel arrangement structure includes a plurality of first pixel sets and a plurality of second pixel sets, the first pixel set includes a plurality of E pixels arranged in a row, the second pixel set includes a center pixel and pixels A, pixels B, pixels C, and pixels D that take the center sub-pixel as a center and are sequentially distributed in a semicircular arc, three separate white light points are formed in each second pixel set, and each separate white light point is formed by the cooperation of the center sub-pixel and any adjacent pixel on the corresponding semicircular arc; and control modes of the first pixel set 1 and the second pixel set 2 are both separate electric control, to control an on-off order and frequency of the separate white light points.
