Freshness constraints of an age of information based event-triggered Kalman consensus filter algorithm Research Articles

Rui Wang, Yahui Li, Hui Sun, Youmin Zhang,h-sun@cauc.edu.cn

Frontiers of Information Technology & Electronic Engineering 2021, Volume 22, Issue 1,   Pages 1-140 doi: 10.1631/FITEE.2000206

Abstract: This algorithm is based on information freshness, which is calculated as the of the sampled data.The proposed algorithm integrates the traditional , information freshness calculation method, and Kalmanthreshold selection method for the ET-KCF algorithm, which compares the packet AoI to the minimum averageAoI of the system.This method can obviously reduce the energy consumption because the transmission of expired information

Cell-free systems in the new age of synthetic biology

Fernando Villarreal,Cheemeng Tan

Frontiers of Chemical Science and Engineering 2017, Volume 11, Issue 1,   Pages 58-65 doi: 10.1007/s11705-017-1610-x

Abstract: The advent of synthetic biology has ushered in new applications of cell-free transcription-translation systems. These cell-free systems are reconstituted using cellular proteins, and are amenable to modular control of their composition. Here, we discuss the historical advancement of cell-free systems, as well as their new applications in the rapid design of synthetic genetic circuits and components, directed evolution of biomolecules, diagnosis of infectious diseases, and synthesis of vaccines. Finally, we present our vision on the future direction of cell-free synthetic biology.

Age-related trends in genetic parameters for wood properties in

Chao SUN, Meng LAI, Shougong ZHANG, Xiaomei SUN

Frontiers of Agricultural Science and Engineering 2017, Volume 4, Issue 4,   Pages 482-492 doi: 10.15302/J-FASE-2017184

Abstract: We observed that age-related trends in overall means varied for different traits: MFA decreased withthe age, while the others generally increased with the age.After the age of 6, genetic correlations were generally higher than phenotypic correlations.Estimates of early selection efficiency suggested that the optimal selection age for wood density wasat age 5–6 years, while it was 9–10 years for the other traits.
