The PMAC and PCR-MAC presented channel selection mechanisms using EWMA-based historical usage prediction to enhance the opportunistic spectrum utilization; the PCR-MAC also exploits the concept of backup channel, adopted from SWITCH [17], to further optimize the spectrum utilization.
Our results suggest that the combination of ocean acidification and nutrients will enhance abundance of opportunistic algal species in coastal systems and will likely drive macroalgal community shifts, based on species-specific responses to future conditions.
Cognitive radios (CRs) are emerging as a promising technology to enhance spectrum utilization through opportunistic on-demand access.
Immunosupression induced by maturation hormones (Pickering and Christie 1980) may also contribute to enhanced susceptibility by even opportunistic microparasites or those previously at a carrier state.
H3K4me3 and histone acetylation may enhance recruitment of the opportunistic, sequence-independent DSB endonuclease Spo11 to specific sites in the genome by loosening local chromatin structures (Kim et al., 2007).
Cognitive radio (CR) is a revolutionary technology in wireless communications that enhances spectrum utilization by allowing opportunistic and dynamic spectrum access.
We introduce an opportunistic scheduling to enhance the physical layer security with transmit antenna selection (TAS) in multiuser environment.
ZR relied on social integration with the Italian culture to establish a bond of trust with Italian partners, reduce opportunistic behaviors, and enhance sensitivity to external information (James 2003).
Therefore, microbiota restoration strategies, which allow beneficial bacteria to thrive, eliminate colonization by opportunistic pathogens, and enhance resistance to intestinal colonization, are required for treatment of H7N9 infection.
Suppressed cell-mediated immunity could enhance the susceptibility to secondary opportunistic infection and contribute to the high mortality caused by post-chemotherapy sepsis (Ayala et al, 1994; O'Sullivan et al, 1995).
