Reduced Complexity Approximation and Design of Gaussian Impulse Response Filters and Wavelets

open access: yesIEEE Access
A systematic method for realizing filters with a Gaussian impulse response is introduced in this work. For this purpose, the Laplace transform is used to obtain the transfer function which corresponds to the Gaussian impulse response. Since this transfer

Scattering Delay Mitigation in High-accuracy Pulsar Timing: Cyclic Spectroscopy Techniques

open access: yesThe Astrophysical Journal, 2023
We simulate scattering delays from the interstellar medium to examine the effectiveness of three estimators in recovering these delays in pulsar timing data. Two of these estimators use the more traditional process of fitting autocorrelation functions to

Characterization of the functional response in the human spinal cord: Impulse-response function and linearity

open access: yesNeuroImage, 2008
Functional magnetic resonance imaging (fMRI) has emerged during the last decade as the main non-invasive technique for the investigation of human brain function. More recently, fMRI was also proposed for functional studies of the human spinal cord, but with controversial results.

Identification of Excitation Parameters Based on TLS - ESPRIT

open access: yesMATEC Web of Conferences, 2018
In order to accurately detect excitation system parameters, this paper presents a algorithm based on the TLS-ESPRIT. The matrix pencil algorithm is used to extract the frequency and damping of each component of system response. So it’s necessary to apply

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Study on modeling of human postural control on frontal-plane during standing (Identication of a transfer function model by frequency response test)

open access: yesNihon Kikai Gakkai ronbunshu, 2015
We have been developing a standing ride type vehicle, such as electric skateboards. A human dynamics model is required to assist balance control of human standing in the vehicle.

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Oil Price Shocks and Stock Markets in Oil Importing Countries: Evidence from Egypt, Morocco, and Jordan

open access: yesScientific Annals of Economics and Business, 2021
This study aims to investigate the dynamic relationship between Oil price Shocks and stock markets returns in Egypt, Morocco, and Jordan as oil-importing countries in the MENA region, over the period (2005-2018). Vector auto regressive regressions (VAR),

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Analysis of sensor impulse response effects on Cramèr–Rao lower bounds for signal parameter estimators

open access: yesThe Journal of Engineering, 2014
In this study, a generic analysis of sensor impulse response effects on linearly filtered channel noise is presented to illustrate the resulting variations to the Cramèr–Rao lower bounds (CRLBs) of signal parameter estimators in signal processing and ...
