Impulse-response functions for chromatic and achromatic stimuli

Journal of the Optical Society of America A, 1993
Thresholds were measured for detecting pairs of briefly flashed stimuli displayed successively at variable onset asynchronies. The stimuli were 1 cycle/deg vertical sinusoidal gratings, modulated either in luminance (yellow–black) or in color (red–green).

Functional Approximation of Impulse Responses

Journal of Monetary Economics, 2018
Abstract A method to estimate the dynamic effects of structural shocks is proposed: “Functional Approximation of Impulse Responses” (FAIR) consists in directly estimating the moving average representation of the data by approximating impulse responses with a set of basis functions. FAIR can offer a number of benefits over alternative impulse response

Impulse-response function of photorefractive phase conjugation

Optics Letters, 1989
Explicit expressions for the impulse-response function of a photorefractive phase conjugator are derived. The expressions are in the form of an infinite series of Bessel functions. The results are derived by using the undepleted pump approximation and are therefore valid at least for small time intervals, even when the conjugator is unstable.

An investigation of the impulse functions for the nonlinear BOLD response in functional MRI

Magnetic Resonance Imaging, 2000
Functional MRI (fMRI) based on blood oxygenation level dependent (BOLD) contrast can be used to detect hemodynamic responses to a broad range of stimuli. It however remains unclear in what fashion the BOLD response is a linear system, and how the impulse function differs with stimulation of varying duration.

Multivariate Quantile Impulse Response Functions

Journal of Time Series Analysis, 2019
A reduced form multivariate quantile autoregressive model is developed to study heterogeneity in the effects of macroeconomic shocks. This framework is used for forecasting and for constructing quantile impulse response functions that explore dynamic heterogeneity in the response of endogenous variables to different shocks.
