Physical bases for determination of scattering kernels from incomplete data in grid-less X-ray imaging [PDF]
A mathematical model for the determination of X-ray scattering kernels’ shapes based on incomplete simulation or measurement data was introduced and tested using a mathematical phantom.

To cluster, or not to cluster: An analysis of clusterability methods [PDF]
Clustering is an essential data mining tool that aims to discover inherent cluster structure in data. For most applications, applying clustering is only appropriate when cluster structure is present. As such, the study of clusterability, which evaluates whether data possesses such structure, is an integral part of cluster analysis. However, methods for

Survival cluster analysis [PDF]
Conventional survival analysis approaches estimate risk scores or individualized time-to-event distributions conditioned on covariates. In practice, there is often great population-level phenotypic heterogeneity, resulting from (unknown) subpopulations with diverse risk profiles or survival distributions. As a result, there is an unmet need in survival

The Number and Distinct Clustering Patterns of Voltage-Gated Calcium Channels in Nerve Terminals
Upon the arrival of action potentials at nerve terminals, neurotransmitters are released from synaptic vesicles (SVs) by exocytosis. CaV2.1, 2.2, and 2.3 are the major subunits of the voltage-gated calcium channel (VGCC) responsible for increasing ...

Detection and analysis of cluster–cluster filaments [PDF]
ABSTRACTIn this work, we identify and analyse the properties of cluster–cluster filaments within a cosmological simulation assuming that they are structures connecting maxima of the density field defined by dark matter haloes with masses $M \, \ge 10^{14}\, h^{-1} \, \mathrm{M_{\odot }}$.
