A Lifetime-Enhancing Method for Directional Sensor Networks with a New Hybrid Energy-Consumption Pattern in Q-coverage Scenarios

An important issue in directional sensor networks (DSNs) is how to prolong the network lifetime in Q-coverage scenarios where each target point may have different coverage requirements.When the Q-coverage requirement is met, it is an effective way to maximize the network lifetime by controlling energy consumptions.Unlike the existing results where

The evolutionarily diverged single-stranded DNA-binding proteins SSB1/SSB2 differentially affect the replication, recombination and mutation of organellar genomes in Arabidopsis thaliana

Single-stranded DNA-binding proteins (SSBs) play essential roles in the replication, recombination and repair processes of organellar DNA molecules.In Arabidopsis NATO straps thaliana, SSBs are encoded by a small family of two genes (SSB1 and SSB2).However, the functional divergence of these two SSB copies in plants remains largely unknown, and det
