  A new inverse method and application to ocean data

  摘要：

  A new method is proposed to inverse normalization data of hidden variables in a dynamical system by embedding a time series in multidimensional spaces and applying a normalization analysis to the conditional probability density of points in the reconstructed phase spaces, The method is robust in the application to Lorenz system and 4-dimensional Rossler system by testing quantitatively and qualitatively the correlation coefficient between inverse data and original data in time domain and in frequency domain, respectively. By applying the method to analyzing the South China Sea data, the normalization data of wind speed is extracted from the sea surface temperature time series.

• Identifying and mapping cDNA fragments related to rice photoperiod sensitive genic male sterility

  日期：2000.3

  The differentially expressed cDNA fragments have been obtained by differential screening with cDNA-RAPD technique in photoperiod sensitive genic male sterile (PGMS) rice. Some of them have been reassessed with Northern blot hybridization, from which a PGMS-related positive fragment, RPG43, has been identified. Further analysis on RPG43 with Southern blot and RAPD indicates that the fragment is a single-copy sequence and its mRNA has been processed after transcription. Sequence analysis reveals that RPG43 is 744 bp in length and contains a 60 bp region (from 126th to 185th bp) showing 72% homology to a human DNA sequence, pac pDJ-356d6, on chromosome 11. So it is a new sequence found in plant and its GenBank access number is AF126027. In addition, RPG43 has been mapped to a position 3.8 cM away from RFLP marker R1553 on chromosome 5 of rice.
