A Real-Number SNP Circuit for the Adder and Subtractor with Astrocyte-like Dendrite Selection Behavior Based on Colored Spikes

Mathematics
In recent years, several proposals have emerged for executing arithmetic operations using different variants of Spiking Neural P (SNP) systems. However, some of these proposals rely on distinct circuits for each arithmetic operation, while others mandate

Together but not scrambled: A perspective on chaotic printing/bioprinting

Aggregate, Volume 5, Issue 4, August 2024.
Chaotic printing is a novel biofabrication technology that exploits the ability of chaotic flows to create predictable and reproducible multilayered structures. This method is based on the use of chaotic mixers, which can produce constructs with highly organized internal micro‐architecture in a simple and cost‐effective way.
