Abstract: Systems and methods for gesture control are described. In some embodiments, a system for assessing a physiological state of a user. The system may include the wearable device comprising one or more electrodes configured to be disposed adjacent to an external surface of the skin portion. A first timestamp may be determined. The first timestamp may indicate a first time at which a stimulus is presented to the user. A second timestamp indicating a second time at which the biopotential signals indicate an intention by the user to perform a responsive action may be determined. Based at least on the first timestamp and the second timestamp, determine a subject response time for the user. The subject response time may be compared to a baseline response time for the user to generate an assessment of a physiological state of the user.

Abstract: A method for cultivating a Tung tree seedling through hypocotyle grafting includes selection of a sand storage time of a rootstock (Vernicia montana Lour.) seed, seedbed construction, scion collection, scion cutting, rootstock cutting, bandaging, transplantation and management, and the like. A grafted plant obtained by a traditional grafting method (bud grafting) for Tung tree is easy to break at a grafting interface; and when the stem grafting is conducted, because a scion is thick, a rootstock for grafting must be cultivated one year in advance. These grafting methods have production problems such as long cycle and high cost, which can be solved by the present disclosure. The present disclosure has a short rootstock cultivation time, simple grafting operations, a high grafting efficiency, and a high survival rate, greatly shortens a cycle of asexual propagation-based seedling cultivation for Tung tree.

Abstract: The present invention relates to a bivalent platinum complex having a structure as shown in a formula (I). The complex has bright green light emission wavelengths, and can be used in the field of OLED organic electroluminescent materials. By means of the structural design, the present invention can improve the heavy atomic effect of phosphorescent materials, enhance spin-spin coupling, and achieve high-efficiency conversion of T1-S0, thereby achieving high luminous efficiency. Furthermore, a platinum complex molecule having an ONCN tetradentate ligand has the advantages of simple synthetic steps, relatively easy coordination and the like, and has may modifiable sites, which can be used for adjusting PL light emission wavelengths and thermal stability. The steric hindrance added by a carbazole group contained can effectively reduce the aggregation effect between molecules, avoid the formation of an exciplex, and further improve the color purity and the luminous efficiency.
