Much time series data is generally from continuous dynamic system. Firstly, this paper studies the detection of the nonlinearity of time series from continuous dynamics systems by applying the Phase-randomized surrogate algorithm. Then, the Delay Vector Variance (DVV) method is introduced into nonlinearity test. The results show that under the different sampling conditions, the opposite detecti...

background: embryo cryopreservation is the process that water is removed from the cell by cryoprotectant materials, and embryos are stored at temperature below zero. this process may affect the viability and developmental potential of embryos. objective: in this study, the effect of the vitrification cryotop method on the expression level of oct4 and mest developmental genes in mouse blastocyst...

ABSTRACT Thousands of microbial taxa in the soil form symbioses with host plants, and due to their contribution plant performance, these microbes are often considered an extension genome. Given effects on it is important understand factors that govern community assembly. Host developmental stage could affect rhizosphere diversity while, alternatively, assemblages change simply as a consequence ...
