Improving the signal-to-noise-ratio in lattice gauge theories [PDF]
, 1997 Renormalization of composite fields is employed to suppress the statistical noise in lattice gauge calculations. We propose a new action which differs from the standard Wilson action by ''irrelevant'' operators, but suppresses the fluctuations of the ...

Phrases in noise test (PINT) Brazil: effectiveness of the test in children with hearing loss
Brazilian Journal of Otorhinolaryngology, 2021 Introduction: One of the main implications of hearing impairment is the difficulty in perceiving speech sounds, especially in noisy environments. Thus, the frequency-modulated system is considered an important educational tool for children with hearing ...
