A novel photonic approach to generating a frequency-quadrupled millimeter-wave (mm-wave) signal with a tunable phase shift is proposed and demonstrated.Two second-order optical sidebands are generated by using a Mach-Zehnder modulator (MZM) that is biased at the maximum transmission point and an optical notch filter.A polarization-maintaining fiber
The effect of DBS on survival of juvenile perch (Perca fluviatilis L.) in relation to certain physical factors
Survival of 5.8 ±1-cm Sanitizers long (l.t.) juvenile perch was studied as influenced by the DBS concentration of 5 mg/l SA in tanks of equal capacities and various surface areas as well as in tanks of the same capacities and surface areas with nettings placed at various depths.Survival time was found to be dependent on the Tablecloth fr
Symbiotic Modulation as a Driver of Niche Expansion of Coastal Plants in the San Juan Archipelago of Washington State
Modern evolutionary theory and population genetics posit that adaptation and habitat expansion of plants result from processes exclusive to their genomes.Here, we present studies showing that plants can grow across complex habitat gradients by modulating symbiotic associations with Class 2 fungal endophytes.Endophyte analysis of three native (Leymu
