All selection signature statistics that have been suggested pick up one or a combination of these signatures, for example, iHS (Voight et al., 2006) is based on the frequency of extended haplotypes within a population, whereas FST (Wright, 1949) uses the divergence of allele frequencies among populations.
Similarly, high frequency of Extended-Spectrum ß Lactamase (ESBL) producing organism belonging to Enterobacter spp. (50%), E. coli (41%), Klebsiella.
Efforts to reduce work hours should focus first and foremost not on the frequency of extended-duration work shifts, but on the duration of consecutive work hours during such shifts.
With a view to get orthogonal families of signals with similar spectra in the space spanned by vectors {v k }k = 1,L, we derive an iterative technique to jointly equalize energies of these vectors in a set of frequency intervals, extending thus the technique proposed in the previous section.
All the models have dominant frequencies comparable to clinical values except for the IMW model, which has a large range of frequencies extending beyond the clinical range for both ventricular tachycardia (VT) and ventricular fibrillation (VF).
The detector allows to measure electric fields in a wide band of frequencies extending from quasi-DC up to about 4MHz, with a sensitivity of the order of 1μV/m in the ULF band.
As this was >24 hours, it implied a mean attack frequency of 2/month, each extending into 2 days.
In particular, in high performance processors, lower temperature translates into fewer reliability concerns, lower cooling costs, the possibility of increasing the operating frequency and extending the device׳s lifetime.
The introduction of MenAfriVac® in the meningitis belt is expected to substantially change the meningitis epidemiology and a key issue will be to evaluate the impact of the vaccine on the frequency and extend of epidemics.
An alternative strategy uses the same dose at the same frequency of administration but extends the period of infusion.
