From four stages of development, we can draw the four laws since the reform and opening up people＇ s congress system changes that adhere to the party＇ s leadership, adapt to changes in the economic system, in theory and in practice, innovation in the legal, institutional design and constantly improve the standard. Four stages and the four laws draw people＇ s congress system experiences, the study of people＇ s congress system in future developments of great significance.展开更多

The eternal term memory vector is determined only by the initial vector that establishes category neuron node and is used to keep the remembrance for this vector for ever. Two times of vigilance algorithm are put forward, and the posterior input vector must first pass the first vigilance of this eternal term memory vector, only succeeded has it the qualification to begin the second vigilance of long term memory vector. The long term memory vector can be revised only when both of the vigilances are passed. Results of recognition examples show that the improved ART-2 overcomes the defect of traditional ART-2 and can recognize a gradually changing course effectively.展开更多

Many fundamental questions, such as flower initiation, light signal transduction, intercellular communication, genomic composition and epigenetic regulation, etc,, have been resolved during the past two decades, Several dedicated plant science journals, such as The Plant Cell, The Plant Journal and Plant ＆ Cell Biology contributed to this progress through the publication of seminal articles that allowed scientists in the community to communicate with each other, to share their expertise and experimental materials.展开更多
