Fig. 1: a Signal from individual incoherent scatterers are summed linearly while they must be summed in quadrature for coherent signals meaning pixel reassignment must be done on the amplitude of coherent emitters in order to properly resolve features. b The phase impacts the total signal measured...
or higher, meaning that the information on the spin-polarization is adequately accumulated. The Ncr is found to be 9, 18, and 57 scans for Tdwell’s of 1.0, 0.5, and 0.1 sec., respectively. Surprisingly, these values are much smaller than the last number of scans determined in an empir...
The main limiting factor in molecular imaging by magnetic resonance imaging (MRI) is its inherently low sensitivity, resulting from low spin polarization at thermal equilibrium and exacerbated by low concentrations in vivo of many compounds of potential interest that contain NMR-active isotopes. These ...
We permit the stochastic processes used to simulate reservoir noise in the model to be complex Hermitean, instead of purely real. We demonstrate in a specific case that this can open the possibility of identifying the precise meaning of the decay rate constants obtained from fluorescence anisotropy...
The comparison shows that for this problem the presented SPH-DEM method can achieve an accuracy similar to that of the grid-based method, meaning that the SPH fluid solver and the SPH-DEM coupling method are reliable. Download: Download high-res image (262KB) Download: Download full-size ...
The disadvantage is that spectral basis functions have no physical meaning in general and their analysis may be a complex task. For example, if the sample is a mixture of two mono-exponentially decaying fluorophores with overlapping spectra but having different lifetimes, two singular values will ...
Back in January, my partner and I resolved to take exercise seriously. This would mean spending hours every week grunting, stretching and sweating our way to better health, which is something that is particularly difficult when you glance at the (weather outside and see dark clouds on the ...
supports can present problems [44]. Measurements in these assays are typically performed in a dry well-plate using an excess of added Eu3+, meaning that contamination by exogenous Eu3+is not an issue, which can be an advantage compared with the DELFIA system....
This is a time-resolved scan, meaning that this is a continuous sequence of multiple rotations, and full-rotation reconstructions can be made at arbitrary points in time. Software implementation , reconstruction parameters and datasets The proposed method is implemented in CTrex, an in-house ...
2), meaning that the results for all sizes of each observer can be captured by a single canonical crowding function. Figure 5 shows the entire data set fit with this model, with critical spacing estimates indicated by the triangle along each function. Figure 5 Entire data set for the 3 ...
