Mechanized dry seeded rice can save both labour and water resources. Rice seedling establishment is sensitive to sowing depth while mesocotyl elongation facilitates the emergence of deeply sown seeds. A set of 270 rice accessions, including 170 from the mini-core collection of Chinese rice germplasm (C Collection) and 100 varieties used in a breeding(More)
—Near-capacity performance of turbo codes is generally achieved with a large number of decoding iterations. Various iteration stopping rules introduced in the literature often induce performance loss. This paper proposes a novel partial decoding iteration scheme using a bit-level convergence test. We first establish decoding optimality of windowed partial(More)
Type I NKT cells, or invariant NKT (iNKT) cells, express a semi-invariant TCR characterized by its unique Vα14-Jα18 usage (iVα14TCR). Upon interaction with glycolipid/CD1d complexes, the iVα14TCRs transduce signals that are essential for iNKT selection and maturation. However, it remains unclear how these signals are regulated and how important such(More)
Waxy maize (Zea mays L. var. certaina Kulesh), with many excellent characters in terms of starch composition and economic value, has grown in China for a long history and its production has increased dramatically in recent decades. However, the evolution and origin of waxy maize still remains unclear. We studied the genetic diversity of Chinese waxy maize(More)
Airway inflammation is mainly mediated by T helper 2 cells (Th2) that characteristically produce interleukin (IL)-4, IL-5, and IL-13. Epidemiological studies have revealed an inverse association between the dietary intake of vitamin A and the occurrence of asthma. Serum vitamin A concentrations are significantly lower in asthmatic subjects than in healthy(More)
—Based on an analysis on the recursive computation of the iterative maximum a posteriori (MAP) algorithm for turbo decoding, this paper considers a modified MAP scheme with reduced block lengths for symbols with unreliable detection after some initial iterations. Applying symbol selection based on cross-entropy measurement for parallel concatenated(More)
Cross-entropy based symbol selection and partial iterative decoding for serial concatenated convolutional codes (SCCC) is developed in this paper. We first apply symbol classification in terms of detection convergence status to all coded bits of the outer code. After that, computations are focused on symbols that have not reached convergence, by applying(More)
This paper considers combining the iterative soft output Viterbi algorithm (SOVA) and the logarithm maximum a posteriori (Log-MAP) algorithm for decoding turbo codes. We examine the differences between the two algorithms and discuss the suitability of combining both algorithms. In the proposed hybrid decoding scheme, frames are first applied with SOVA(More)
Long impulse response system identification presents two challenges for standard normalized least mean square (NLMS) filtering method: heavy computational load and slow convergence. When the response is sparse, partial update algorithms can reduce the computational complexity, but most often at the expense of performance. This paper discusses the tap(More)
