what is the difference between the particle density (true density of the solid material) and the bulk density (including voids) of a powder, and how can both be expressed in pcf

Pseudorandom correlation functions (PCF), introduced in the work of (Boyle et al., FOCS 2020), allow two parties to locally gen- erate, from short correlated ...
