The amplitude of the first negative (N1) component of the evoked potentials to consecutive individual pulses in the train was measured by using a subtraction method.
These new P. yoelii data included oocyst-stage sporozoites, blood-stage parasites, late-stage gametocytes and 36 and 40 hour liver stage parasites obtained by a cDNA subtraction method.
After 52 weeks, participants switched to NPH insulin and continued with OADs for a 1-week washout period for accurate assessment of anti-insulin antibody levels by a subtraction radioimmunoassay method (23, 24).
Here, we report that by using a sensitive subtraction method, we identified new spaceflight-inducible genes in cancer cells that were not identified by microarray.
The structure and underneath soil profile are analyzed as a unified model by the subtraction method.
The distance between the two measurement sites was determined by the subtraction method, hence by subtracting the distance between the sternal notch to the carotid artery from the sternal notch to the femoral artery.
Inspection of the original scanned image revealed that these outliers were produced by a faulty background subtraction method that extracted signals from the scanned image.
The stripe with negative pixel values along x direction at position z = 7.5 mm also results from a time varying background that could not be removed by the subtraction method.
Monomer sequence of O/H copolymers was determined by 13C NMR and the changes in triad concentration were obtained by spectra subtraction method.
Finally, absorbance was measured at 260.5 nm (after removal of AML spectrum by ratio subtraction method) for determination of the total concentration of OLM and HCT (hence OLM by subtraction).
