Abstract: The subject invention is concerned with systems and methods advantageously applying finite element analysis to establish design rules for a highly sensitive piezo-resistive pressure sensor with an output that is high enough to be detectable by simple and inexpensive circuits and therefore ensure wearability. Four frequently reported micro-feature shapes in micro-patterned piezo-resistive sensors are provided, where the micro-dome and micro-pyramid yield the highest sensitivity. Investigations of different conductivity values of micro-patterned elastomers show that coating the elastomer with a conductive material (e.g., a metallic coating) leads to higher current response when compared to composited conductive elastomers. Advantageous geometric parameters and spatial configurations of micro-pyramid design of piezo-resistive sensors are provided.

The light field generated in the present invention simultaneously has linear polarization, elliptical polarization, and circular polarization in a cross section of the light field, and in a propagation process of the light field in free space, apart from normal spot size scaling, polarization distribution remains unchanged.

Abstract: A method for implementing formal verification of an optimized multiplier via symbolic computer algebra (SCA)-satisfiability (SAT) synergy includes: systematically recovering, by a reverse engineering algorithm, an adder tree from an optimized multiplier; 2) generating, by a constraint satisfaction algorithm, a reference multiplier only by using an adder based on a constraint condition; and 3) combining, by an SCA-based and SAT-based verification method, complementary advantages of SCA and SAT. In the verification framework, the method introduces a reference multiplier generator for generating a correct reference multiplier. The correct reference multiplier has both a structure similar to a structure of the optimized multiplier and a clear adder boundary. The clear adder boundary allows proving correctness of the correct reference multiplier through SCA-based verification.

Abstract: The invention discloses a plant thermo-sensitive male sterile gene mutant tms15 and uses thereof. The nucleotide sequence of the plant thermo-sensitive male sterile gene mutant tms15 is SEQ ID No. 1. The inventor screened the thermo sensitive genic male sterile mutant tms15 by EMS mutagenesis of Zhonghua 11, which showed a male sterile phenotype under high temperature conditions (>28° C.) and restored fertility under low temperature conditions (22˜24° C.). The cytological results shows that the sporogenous cells in tms15 plants proliferated excessively and the tapetum cells are also vacuolized abnormally under high temperature. The normal proliferation of sporogenous cells and the normal development of tapetal cells are restored to some extent after low temperature treatment.
