In this study, we describe the design and fabrication of a dual-frequency catheter using a bidirectional transducer stack with center frequencies of approximately 30 and 80 MHz.
In addition, the operating frequencies of the mobile phone standards (UMTS) are also in the range of frequencies of approximately 0.9 (GSM) or 2.1 GHz (3G).
Spectral properties of Doppler velocity variations from the radars revealed that plasmaspheric Pi2 pulsations observed on August 19, 2010, in the Doppler velocity data had common dominant frequencies of approximately 12 to 14 mHz (f 1) and 23 to 25 mHz (f 2).
In other recombinases, R4, TP901-1, Bxb1 integrases and FLPe showed average recombination frequencies of approximately 82.4, 39.3, 94.1 and 17.2%, respectively (Fig. 2C).
With four individuals in each pool, frequencies of approximately 25% for each individual were expected.
The 1000 Genomes project has described the location and allele frequencies of approximately 15 million SNPs, 1 million short insertions and deletions, and 20 000 structural variants.
TRF2 depletion triggered fusion frequencies of approximately 17.6%, whilst concomitant Brca1 deletion caused a reduction to 8.2% (Fig 2B), in the same range as CtIP depletion (6.6%).
Copy-number alterations at 9p21 and 17p13 have been associated with loss of the tumor-suppressor gene INK4A and mutations in p53 at frequencies of approximately 25% and less than 10%, respectively (for a review, see [ 60]).
We estimated the study had sufficient power (1-β = 80%, P = 0.05) to detect a minimum of 17% difference in genotype frequency between chorioamnionitis and no chorioamnionitis for frequencies of approximately 10% (ie. 10% versus 27%).
For example, approximately 3% of African Americans carry the double homozygous 309G/G locus compared to frequencies of approximately 30% in the Japanese and Korean populations [ 12, 13, 15, 31].
Glutathione S-transferase P1 expression in cancer patients may also be influenced by the presence of allelic variants— GSTP1 Ile105Val (rs1695) and GSTP1 Ala114Val (rs1138272), with homozygote rare allele frequencies of approximately 12% and 2% in the Caucasian population, respectively (Zimniak et al, 1994; Ali-Osman et al, 1997; Harries et al, 1997; Sachse et al, 2002).
