The APETALA1 (AP1)/FRUITFULL (FUL)-like transcription factor OsMADS18 plays diverse functions in rice development, but the underlying molecular mechanisms are far from fully understood. Here, we report that down-regulation of expression RNAi lines caused a delay seed germination and young seedling growth, whereas overexpression produced plants with fewer tillers. In targeted genome-edited mutants (osmads18-cas9), an increased number tillers, altered panicle size, reduced setting were...

Combining adaptive heartbeat mechanism with fuzzy grey prediction algorithm, a novel implementation of failure detector is presented. The main parts the are layer and rule-based classification layer. former employs GM(1,1) unified-dimensional new message model, only needs small volume sample data, to predict arrival time dynamically. Then, value loss rate in specific period act as input variations for latter decide failure/non-failure. Furthermore, algorithms how construct system...

The Neville‐type algorithms are widely used in engineering and sciences. As an analog of Neville's algorithm that deals with univariate polynomial interpolation, Bulirsch‐Stoer is a classical one for rational interpolations. It can be applied to calculating the value interpolating function at given point or recovering functions. In this paper, we generalize multivariate cases two versions different situations. These generalizations recursive algorithms. first suitable calculate other...
