Initial experimental results indicate that a spring stiffness of around 30 MN/m is at the limit of detectability.
Adsorption of Cl− and HSO4− at Pt(111) is very fast and at the limit of detectability.
The lower limit of detectability using vesicles with entrapped Tb3+ or DPA was about 50 μM phospholipid.
The effect is of a magnitude that remains close to the limit of detectability, or many measurements are necessary because of the very low statistical significance of the results.
The samples giving discordant results generally had levels of HCMV DNA close to the limit of detectability or had been stored for prolonged periods.
Deletions of between 32 and 190 base pairs, which are at or below the limit of detectability by conventional electron microscopic analysis of heteroduplex DNAs, have been located in this way.
The limit of detection (detectability), detection index, broadening index, modified contrast index, densitometric visualizing index, and linearity range were determined and tested for estradiol, tocopherol, tocopherol acetate, ibuprofen, stearic acid, stearyl alcohol, and salicylanilide detected by the use of visualizing reagents.
Using a 3D, digital bar phantom and a material sensitivity matrix calibrated for use with a polychromatic x-ray source, we quantify the limits of detectability (CNR = 5) afforded by spectral diffusion in the triple-energy material decomposition of iodine (3.1 mg mL -1)), gold (0.9 mL -1(-1)), and goldlinium (2.9 mg mL(-1)) concentrations.
These images, based on simulations of realistic distributions of prostate cancer PET tracers, hint that it is possible to push the past limits of detectability and localization of small tumors in the pelvic area, if using the present generation of TOF PET scanners.
Using a digital resolution phantom, the mean limits of detectability (mean CNR = 5) for each element are determined to be 2.3 mg mL -1) (18 mL -1or iodine and 1.0 mM mL(-1) (5.1 mM) for gold, well wiodinethe observed in vivo concentrandons of each element (I: 0-24 mg mL(-1.0 Au: 0-9 mg mL -1)) and a factor of 10 imL -1emMnt over the limits without post-reconstruction spectral fortration.
Among those patients receiving indinavir, AZT and 3TC, the team reported, 82% showed a drop in blood HIV levels below the limits of detectability and sustained the drop for more than a year.
