Abstract: The present disclosure discloses a methicillin-resistant staphylococcus aureus mutant strain and use thereof, and belongs to the field of molecular biology and microorganisms. The methicillin-resistant staphylococcus aureus mutant strain disclosed by the present disclosure has a relatively low exopolysaccharide synthesis ability and a relatively low biofilm metabolism ability, but it is sensitive to an antibiotic cefoxitin. The mutant strain can be used for treating a related disease caused by methicillin-resistant staphylococcus aureus infection through an endogenous ecological treatment strategy. The present disclosure provides a new idea for treating the disease.

Abstract: A method is disclosed for designing a sparse array for an automotive radar. The method moves each of a number of antenna elements to candidate neighboring grid positions starting from an initial random seed placement to iteratively search for a placement of antenna elements that improves upon a cost function. The cost function for each candidate placement may be determined from characteristics of the FFT response associated with the candidate placement. The method may search for a candidate placement with the lowest cost function among the multiple candidate placements based on the random seed placement. The search may be repeated for a large number of random seed placements to find the candidate placement with the lowest cost function corresponding to each random seed placement. The method may compare the lowest cost functions corresponding to the multiple random seed placements to determine an optimized placement having the minimum cost function.

Abstract: A method is disclosed for suppressing sidelobes due to artifacts introduced by FFT operations during automotive radar signal processing. Sidelobes of a stronger target from the FFT operations may bury the response from a weaker target when there are multiple targets. The method estimates the sidelobes of an identified target from a measured FFT response and subtracts the estimated sidelobes from the measured FFT response. The identified target may be the strongest target from the measured FFT response. The method estimates the sidelobes to suppress the sidelobes with respect to the peak signal of the identified target. After the estimated sidelobes of the identified target are removed, the updated FFT response may reveal other targets that had been buried. The method may identify additional targets to estimate their sidelobes and may iteratively remove the estimated sidelobes of additional targets from the FFT until a desired sidelobe residual level is achieved.
