Although frequently reported, radial strain is less reproducible because of the reduced resolution of imaging in the radial direction as opposed to the circumferential or longitudinal directions. There are a number of different methods to quantify strain: registration methods, feature-based tracking ...
It is known that immunity and stress responses are induced in aging22,23 and that excessive glia activation is a feature of AD40; this points at age-dysregulation of immunity as a possible mechanism in AD. Regulation of cell death was present as a top category in age-dysregulated changes, ...

Eq. (1), whereXandYare two samples feature sets. This function turns to Manhattan or Euclidean distance function in most of the cases by using thep = 1orp = 2, respectively. Finding and selection of the optimal value of thekhyper-parameter is the most crucial stage in the ...
A strong radial ¯ow directed towards the center is evident near the wall. In the vicinity of the vortex core, the ¯ow turns downwards away from the wall. The boundary layer azimuthal vorticity is too thin to be seen clearly (i.e. resolved) at t 5, shown in Fig. 7c. A ...
Cell barcodes and UMI (unique molecular identifiers) barcodes were demultiplexed and single-end reads aligned to the reference genome, GRCh38, using the CellRanger pipeline (10X Genomics). The resulting cell-gene matrix contains UMI counts by gene and by cell barcode. Analysis of CNAs and ident...
