Key message Shuhui498 (R498) is an elite parent of heavy panicle hybrid rice by pyramiding the rare gn1a and null gs3 alleles. This finding reveals the genetic basis and great potential application in future breeding of R498. Abstract The heavy panicle trait, defined as 5 g or more of grain weight per panicle, is one of the target traits in super-high-yield rice breeding programs. The use of heavy...
Micro-turbine (MT) is characterized with fast response and high efficiency, thus is an ideal candidate to be included in the hybrid renewable energy generation systems. However, MT exhibits rather complex dynamics, bringing about technical challenge in control design and stability analysis. This paper is concern with modeling and control design for MT system under stand-alone operation. A comprehensive...
This paper studies fundamental housing values and housing bubbles based on Time-varying Present Value model. Using data of four typical cities in China, our results preclude the existence of housing bubbles in Tianjin and Chongqing. We further preclude the existence of explosive and intrinsic bubbles, but include that of momentum bubbles in Beijing and Shanghai, which accounts for 18.4% and 8.5% of...
We combined the finite rate of innovation (FRI) method with singular value decomposition (SVD) theory and got an improved sampling algorithm of non-band limited signals. It used SVD instead of annihilating filter in FRI method to reduce noise. We took streams of diracs signal as an example and deduced the detailed sampling and reconstruction process in the improved algorithm. It first found DFT coefficients...
