Pion distribution amplitude from lattice-QCD [PDF]

open access: yes, 2013
A method is explained through which a pointwise accurate approximation to the pion's valence-quark distribution amplitude (PDA) may be obtained from a limited number of moments.

Descriptional complexity of pushdown store languages [PDF]

open access: yes, 2012
It is well known that the pushdown store language P(M) of a pushdown automaton (PDA) M — i.e., the language consisting of words occurring on the pushdown along accepting computations of M — is a regular language. Here, we design succinct nondeterministic

Color Engineering of Silicon Nitride Surfaces to Characterize the Polydopamine Refractive Index [PDF]

open access: yes, 2018
A simple methodology to generate polydopamine (PDA) surfaces featured with color due to thin-film interference phenomena is presented. It is based on depositing ultra-thin films of polydopamine on a Si/Si 3 N 4 wafer that exhibits an interferential ...
