We also indicate that the flower senescence is the result which the balance of senescence factors is broken and C 2H 4 likely is the linker among the senescence factors.

Current advances in studies of longevity and aging genesand their relevant genes;

It offers some determinate method of the attenuation factor.

In this paper a measurement method for attenuation factors of the vibration of the thin-shell structures is proposed,in which the acoustic measurement in the sound field near the structure is applied instead of the vibration measurement on the radiating surface.

Basec on simulating human brain to be remember by the part and that associating the whole characteristic as the foundation,and by inducting the associative memory attenuation factor,the neutral network structure and the learn arithmetic were developed apply in the system of fault diagnose in time.

Research on a piecewise mathematical model with decay factor for battery

To study the significant effect of keywords in information filtering and classification in scientific journals,In this paper,we empirically investigated statistical characteristics of keywords in a top-acade-mic journal,namely Proceedings of National Academy of Science of the United States of America(PNAS),including the frequency distribution,the temporal scaling behavior,and the decay factor.

This paper discusses a simple VaR method for linear instrument in which the volatility of return is computed by the Exponentially Weighted Moving Average(EWMA) method,and the optimal decay factor is determined by the Root Mean Squared Error(RMES) criterion.
