Founded in 2008, Fairfax, Virginia-based LastPass had 7 million users at the time of the acquisition, across both the consumer market and the enterprise.
We assess the accuracy of parcellations from four different aspects: (1) reproducibility across different acquisitions and groups, (2) fidelity to the underlying connectivity data, (3) agreement with fMRI task activation, myelin maps, and cytoarchitectural areas, and (4) network analysis.
Besides accuracy, reproducibility is also an essential property for image segmentation algorithms and includes reproducibility across different acquisitions and reconstructions [3 6], multiple observers [7], different segmentation algorithms [8], and different bin ranges [6].
Subsequently, using a procrustes algorithm in Matlab (R2015b, Mathworks©), the position (3-D translations and rotations) of the prosthesis with respect to the bone was calculated across two acquisitions (one with two, two with three, etc).
Spread that across five acquisitions and you would would create more new entrepreneurs, startups and investors than a decade of SEIS grants.
The total time for the R-fMRI time series (10 minutes), the spatial resolution (3 mm isotropic with 36 slices), and the TE (40 ms) were kept constant across all acquisitions.
Despite this, we showed high intraobserver reproducibility across multiple acquisitions.
Further, visual colour assessment of maximum stiffness in the lesion or surrounding tissue on a single acquisition was highly correlated with measured maximum Emax across three acquisitions.
A factor that is likely to affect reproducibility is the two-dimensional nature of conventional ultrasound, both B-mode and elastography, with resulting differences in slice selection across acquisitions, and we did not compare the reliability of SWE imaging in all planes.
Across acquisitions and preprocessing streams, anatomical brain networks were found to be sparsely connected, hierarchical, and assortative.
According to Andy Baio of Wired, the median cost across all the acquisitions is about $92 per user.
