Interactions between acoustic challenges and processing depth in speech perception as measured by task-evoked pupil response

open access: yesFrontiers in Psychology, 2022
Speech perception under adverse conditions is a multistage process involving a dynamic interplay among acoustic, cognitive, and linguistic factors. Nevertheless, prior research has primarily focused on factors within this complex system in isolation. The

Composition depth profile analysis of electrodeposited alloys and metal multilayers: the reverse approach [PDF]

open access: yes, 2011
The reverse depth profile analysis is a recently developed method for the study of a deposit composition profile in the near-substrate zone. The sample preparation technique enables one to separate the deposit and a thin cover layer from its substrate ...

Analysis of losses in 2D photonic crystal waveguides using the 3D finite difference time domain (FDTD) method [PDF]

open access: yes, 2002
The 3D FDTD method is used to obtain loss versus hole depth in a 2D photonic crystal waveguide by simulating two different length guides. The transmission results are validated against published measured data.
