  • Publication number: 20250197461
    Abstract: In the present disclosure, a yeast interactive plasmid of a detoxifying enzyme glucosinolate sulfatase (GSS1) is constructed based on a yeast two-hybrid system and then screened with an Arabidopsis thaliana-yeast library, and a plant protein zeaxanthin epoxidase aba1 that interacts with the GSS1 is obtained for the first time. A zeaxanthin epoxidase gene, also known as an aba-1 gene, is an abscisic acid (ABA) synthase that can catalyze oxidative conversion of the zeaxanthin into all-trans violaxanthin, thereby generating carotenoid precursors required in an ABA biosynthetic pathway. Furthermore, a core peptide segment that interacts with the aba1 is obtained by continuously reducing the length of a GSS1 sequence and conducting one-to-one yeast two-hybrid verification with the aba1 sequence.

  • Patent number: 11619578
    Abstract: A method for determining an optical constant of a material includes: acquiring ellipsometric parameters; obtaining a optical constant of the material corresponding to the ellipsometric parameters by a machine learning model; the machine learning model including a mapping relationship between the ellipsometric parameters and the material optical constant of the material corresponding to the ellipsometric parameters. The method uses the machine learning model to implement an automatic fitting of ellipsometric parameters. In the method, the optical constant of the material is calculated by a machine learning model, which no longer depends on the experiences of the experimenters, thereby reducing requirements for the operator, accelerating the fitting of the data curve when calculating the optical constants of the material and improving the operation efficiency.

  • Patent number: 9977133
    Abstract: Examples are provided that enable a cellular network location assist to confirm a position determined using a sensor of a mobile device. As a result of global positioning system signals becoming unavailable due to the mobile device traveling indoors, the mobile device implements a sensor-based position determination that provides a position of the mobile device as the mobile device travels about a location. In order to confirm the reliability of the sensor-based position determination, the mobile device, after passage of time or after traveling some estimated distance, requests location assistance indications from the cellular network. A processor of the mobile device receives the location assistance indications and generates a directional vector based on several of the location assistance indications. Using the directional vector, the processor confirms the reliability of the dead reckoning position.
