Abstract: Provided are a display panel and a display device. An isolation dam is provided in a peripheral area of the display panel. The display panel includes: a display functional layer comprising a plurality of display signal traces; and a touch-control functional layer comprising a plurality of touch-control signal traces. On the binding side, there are a first boundary and a second boundary, and a first trace area located between the first boundary and the second boundary, the first boundary is closer to the display area than the second boundary. In the first trace area, the touch-control signal trace is arranged along a first direction and are led out from the binding circuit and connected to the touch-control pattern via the isolation dam and the first trace area in sequence, the display signal trace is arranged along a second direction and intersects with the touch signal trace.

Abstract: A preparation method of itaconate-butadiene bio-based engineering rubber belongs to the bio-based engineering rubber area. The bio-based engineering rubber of the present disclosure is formed through chemical crosslinking of copolymers, which are formed by polymerization of itaconate and butadiene emulsion. The number average molecular weight of the itaconate-butadiene copolymer is about 53000-1640000, and weight-average molecular weight is about 110000-2892000. Itaconate-butadiene copolymers are formed by polymerization of itaconate and butadiene emulsion, then and chemical crosslinking of the copolymer is performed to form bio-based engineering rubber using a traditional sulfur vulcanizing system. The bio-based engineering rubber has high molecular weights as well as lower glass-transition temperatures and can be vulcanized using the traditional sulfur vulcanizing system.

Abstract: The present invention discloses a quantum computing method for expressway traffic flow distribution simulation considering destination selection. The method comprises the following steps. (1) Construct an expressway exit and entrance network structure. (2) Use a complex number to represent direction-and-flow superposition states of vehicles. (3) Construct a model and setting parameters. (4) Simulate a quantum random walk. (5) Perform model check and time-space matching. and (6) Fit and compare the quantum random walk with real flow data. The present invention can simulate the characteristics of quasi-periodic oscillation and irregularity in expressway traffic flow, closely integrate traffic observation data and reveal the deep characteristics of traffic behavior from a new perspective, thus increasing the accuracy and efficiency of expressway traffic flow simulation.

Abstract: The present invention provides a method for analyzing the non-observed effect concentration (NOEC) of a chemical on an organism. The analysis method includes the following steps: 1) conducting a chronic toxicity test on a test organism with a test chemical at different concentrations, and conducting assays to obtain several sets of endpoint effect data; 2) classifying the several sets of endpoint effect data obtained in step 1); and 3) constructing hypothesis testing models with the data classified in step 2), and according to the statistical significance values from hypothesis testing models, among the same set of endpoint effect data, adopting the highest concentration of the test chemical that do not produce a significant effect as NOEC within the set; and among the different sets of endpoint effect data, adopting NOEC of the set with the smallest NOEC value as NOEC of the test chemical on the test organism.

Abstract: The present disclosure involves a preparation method of bio-based silica/poly (itaconate-ter-isoprene-ter-glycidyl methacrylate) nanocomposite. Bio-based silica/poly (itaconate-ter-isoprene-ter-glycidyl methacrylate) nanocomposite is environment-friendly, and silica and poly (itaconate-ter-isoprene-ter-glycidyl methacrylate) are derived from non-petroleum base materials, which do not rely on fossil fuel. Compared with nanocomposite without nanocomposite, nanocomposites with glycidyl methacrylate have better silica diffusion, mechanical properties and wet-skid resistance of rubber product are improved while consuming the same time. Further, rolling resistance is decreased so that using silane coupling agent is avoided. Therefore, the processing technology is simplified, and VOC emission is avoided. It is a kind of “green tire” rubber product.
