A new approach to the generalized transfer function and its application to biomedical signal analysis [PDF]

, 2000
In this paper, we present a method for modeling an electrocardiogram (ECG) signal using time-varying parameters by considering that the signal is generated by a linear, time-varying (L TV) system with a stationary white noise input, and then by ...

Dynamic Cerebral Autoregulation Reproducibility Is Affected by Physiological Variability

Frontiers in Physiology, 2019
Parameters describing dynamic cerebral autoregulation (DCA) have limited reproducibility. In an international, multi-center study, we evaluated the influence of multiple analytical methods on the reproducibility of DCA.

Boundary Analysis of Control Systems using Schwarz Lemma

International Journal of Pioneering Technology and Engineering, 2022
In this paper, Schwarz lemma at the boundary is considered for analysis of transfer functions used in control systems. Two theorems are presented with their proofs by performing boundary analysis of the derivative of positive real functions evaluated at ...

Dynamic cerebral autoregulation is intact in chronic kidney disease

Physiological Reports, 2022
Chronic Kidney Disease (CKD) patients experience an elevated risk for cerebrovascular disease. One factor that may contribute to this heightened risk is an impairment in dynamic cerebral autoregulation, the mechanism by which cerebral vessels modulate ...

Sport-Related Concussion Alters Indices of Dynamic Cerebral Autoregulation

Frontiers in Neurology, 2018
Sport-related concussion is known to affect a variety of brain functions. However, the impact of this brain injury on cerebral autoregulation (CA) is poorly understood. Thus, the goal of the current study was to determine the acute and cumulative effects

Modulation Transfer Function Analysis in Myopic Model Eye

ASM Science Journal, 2021
Hitherto, the eye modelling is based on the emmetropic eye taken its ocular optical components value from the population-based studies. However, no studies have been done to study the effect of aberration of myopic refractive error by modelling the eye ...

ENERGY TRANSFER IN TRIMERIC C-PHYCOCYANIN STUDIED BY PICOSECOND FLUORESCENCE KINETICS [PDF]

, 1986
The excited state kinetics of trimeric C-phycocyanin from Mastigocladus laminosus has been measured as a function of the emission and excitation wavelength by the single-photon timing technique with picosecond resolution and simultaneous data analysis. A

Pixel Crosstalk and Correlation with Modulation Transfer Function of CMOS Image Sensor [PDF]

, 2005
The Modulation Transfer Function is a common metric used to quantify image quality but inter-pixel crosstalk analysis is also of interest. Because of an important number of parameters influencing MTF, its analytical calculation and crosstalk ...

Alternate quantification approaches for cold-induced vasodilation in human glabrous skin

Frontiers in Physiology
IntroductionCold-induced vasodilation (CIVD) is a counterintuitive focal increase in glabrous skin blood flow during cold exposure with unclear local and neural mechanisms.MethodsWe tested 12 (8 men, 4 women) healthy subjects’ laser-Doppler flux (LDF ...
