In cognitive wireless multi-hop networks,the spectrum resources are highly Ice Cream Cone Dispensers variable and diverse.A cross-layer multi-channel MAC protocol combined with QoS search was proposed.The protocol combines the on-demand QoS search with dynamic spectrum allocation via cross-layer method,which only permits the transmission nodes to p
Sustainable Oil and Profitable Wind: The communication of corporate responsibilities as inverted positioning
Companies are confronted with differing public perceptions, which influence the C way in which they present their social and environmental responsibilities.Our qualitative study compares the online responsibility communication of two companies from the energy sector: Shell, representing the controversial but profitable oil industry; and Vestas, rep

Rewiring of Gene Expression in Pseudomonas aeruginosa During Diauxic Growth Reveals an Indirect Regulation of the MexGHI-OpmD Efflux Pump by Hfq
In Pseudomonas aeruginosa, the RNA chaperone Hfq and the catabolite repression protein Crc act in concert to regulate numerous genes during carbon catabolite repression (CCR).After alleviation of CCR, Reusable Masks the RNA CrcZ sequesters Hfq/Crc, which leads to a rewiring of gene expression to ensure the consumption of less preferred carbon and n
