The high momentum airflow will be produced by the oscillation of the circular FSMA composite diaphragm close to its resonance frequency driven by electromagnets.
A cantilever structure was oscillating at its natural frequency driven by thermal noise, this feature can also be used to calibrate the cantilever spring constant [38] and to gain the G-factor of the device [30].
The bottom two magnets rotated at certain frequency driven by a step motor, which was controlled using a functional signal generator.
Here, information transmission is compromised by synchronized inputs from the basal ganglia at frequencies in and below the beta band, but not by those at higher frequencies driven by DBS (Rubin & Terman, 2004; Guo etal., 2008; Cagnan etal., 2009; Moran etal., 2012).
Increased spatial variation in nutrient availability could also produce variation across subpopulations in access to nutrients that might obscure fitness differences between genotypes (Figs 4 and 5; van Noordwijk and de Jong 1986; Reznick et al. 2000) and result in changes in genotype frequency driven solely by variable resources (Table 1: H13).
As expected, wave action is found to be dominated in a certain frequency range driven by the wind forcing, while it is also diffused to lower frequencies by means of (wind-induced) oscillations in vegetation.
Olson et al. (2013) argued that the transition from low to high reversal frequency is driven by the supercontinent cycle.
Another choice, which is f(t) = m, ω(t) = ω0, h1 ≠ 0, and all other time functions are zero, gives simple harmonic oscillator of natural frequency ω0 driven by arbitrary time-dependent forces.
Wetter and colder conditions at the mid-to-late Holocene transition (4000 3000 cal yr BP) led to a decrease in fire frequency, probably driven by both climate and a subsequent reduction in human land use.
Recently, instead of label-free detection using cantilever bending deflection, there has been an alternative in the label-free detection based on evaluation of cantilever's resonant frequency shift driven by molecular interaction on a cantilever surface.
MHC polymorphism is functionally relevant and is thought to be maintained by selection through the mechanisms of heterozygote advantage and frequency dependence, driven by the host-pathogen interactions and, in some cases, disassortative mating preferences (reviewed in [ 2]).
