The Progress in Using 3-D Printing Wastes Towards a Circular Economy [PDF]

open access: yesE3S Web of Conferences, 2023
Additive manufacturing (AM) is a growing technology due to its ability to improve contemporary production techniques. However, resultant waste from the involved processes is a growing concern. In this mini-review, we explore on the strategies that can be

Sum Rules of Neutrino Masses and CP Violation in the Four-Neutrino Mixing Scheme [PDF]

open access: yes, 2001
We show that the commutator of lepton mass matrices is invariant under terrestial matter effects in the four-neutrino mixing scheme. A set of model-independent sum rules for neutrino masses, which may be generalized to hold for an arbitrary number of ...
