Nonparametric transfer function models [PDF]

open access: yesJournal of Econometrics, 2010
In this paper a class of nonparametric transfer function models is proposed to model nonlinear relationships between 'input' and 'output' time series. The transfer function is smooth with unknown functional forms, and the noise is assumed to be a stationary autoregressive-moving average (ARMA) process.

A novel modeling method for forward-flyback converter and investigating proper design with guidelines to eliminate right half plane zeros [PDF]

open access: yesAUT Journal of Electrical Engineering
The main advantages of the flyback converter are the simple topology and the isolation of the output from the primary, which is useful for cases where a compact design is required.

Frequency-Domain Analysis of Linear Time-Periodic Systems [PDF]

open access: yes, 2004
In this paper, we study convergence of truncated representations of the frequency-response operator of a linear time-periodic system. The frequency-response operator is frequently called the harmonic transfer function. We introduce the concepts of input,

Transfer of Functional Cargo in Exomeres [PDF]

open access: yesCell Reports, 2019
Exomeres are a recently discovered type of extracellular nanoparticle with no known biological function. Herein, we describe a simple ultracentrifugation-based method for separation of exomeres from exosomes. Exomeres are enriched in Argonaute 1-3 and amyloid precursor protein.

Rational inner functions in the Schur-Agler class of the polydisk [PDF]

open access: yes, 2010
Every two variable rational inner function on the bidisk has a special representation called a transfer function realization. It is well known and related to important ideas in operator theory that this does not extend to three or more variables on the ...

Linear and nonlinear identification of the carotid sinus baroreflex in the very low‐frequency range

open access: yesPhysiological Reports, 2022
Since the arterial baroreflex system is classified as an immediate control system, the focus has been on analyzing its dynamic characteristics in the frequency range between 0.01 and 1 Hz. Although the dynamic characteristics in the frequency range below
