DWI images were acquired in three orthogonal directions and then combined into a single trace image.
Typical performance of one, moderate stage patient, in a single tracking task and in a single tracing task, along a circular path, is illustrated in figure 2. It can be seen that neither tracking nor tracing are smooth and that the measures depicting VMC performance errors have high values relative to mean normal control values that are taken from our previous database.
The database could therefore diverge from the actual pattern of connectivity especially by erroneous 'absences' of projections, which cannot be detected in a single tracing experiment.
"How is it possible to find traces of Guede in enormous quantities but not a single trace of Amanda?" Ms Bongiorno asked the appeals court in Florence.
The dinucleotide difference is less well supported, with just a single trace covering it in one assembly, though the corresponding bases in this trace are good quality.
Open image in new window Fig. 8 a A single trace of land-streamer seismic data (red) overlain with a single trace of conventional spiked geophone data (blue).
A single tracing is virtually diagnostic in a high proportion of cases, and serial tracings may confirm the diagnosis.
The observation of single molecule ZAP70-EGFP accumulation in a single intensity trace (i.e., several consecutive step intensity increases) is technically challenging due to the convolution of several time-dependent processes: MCC-Atto647N bleaching, ZAP70-EGFP bleaching, pMHC TCR unbinding, ZAP70-ITAM binding, and ZAP70-ITAM unbinding.
Urinary total arsenic concentration was measured in the baseline spot urine sample by graphite furnace atomic absorption spectrometry (AAnalyst 600 spectrometer; PerkinElmer, Norwalk, CT, USA) with a detection limit of 2 μg/L, in a single laboratory (Trace Metal Core Laboratory at Columbia University) (Nixon et al. 1991).
