Vascular tree structure-based perfusion phantom fabrication using modified Hele-Shaw cell method

Tissue phantoms mimicking microvasculature and perfusion are essential for vasculature modelling and calibrating imaging systems, which require faithful replication of vascular geometry and flow. Conventional fabrication methods, including lithographic micromachining and additive...

ZSH: Rank-Weighted Profiling of Bitcoin Transactions and a Pre-Specified Evaluation of What the Profiles Capture

Bitcoin’s ledger records what each transaction moves but not what it does; unsupervised profiles describe it without labels, but are rarely tested against information the clustering never saw. We evaluate ZSH, which weights twelve features by the rank of their mutual information...
