Comparative Analysis of the Effect of Renal Function on the Spectrum of Coronary Artery Disease

The American Journal of Medicine, 2020
We aim to assess the differential effect of renal impairment across the spectrum of patients with ischaemic heart disease and to study if any established risk factors may modify this risk.A total of 2013 patients who underwent revascularization for ST-segment elevation myocardial infarction or invasive physiology assessment were included.

Performance function for equally-spaced digital spectrum analysis

IEEE Transactions on Instrumentation and Measurement, 2001
A different procedure for evaluating the errors introduced by the equally-spaced sampling technique in the asynchronous spectral analysis of a periodic signal was introduced. It is based on the assumption that the initial sampling instant can be randomized so that each estimated spectral component can be considered a random variable characterized by ...

Autonomic function in narcolepsy: power spectrum analysis of heart rate variability

Journal of Neurology, 1997
Ten narcoleptic patients that had never been treated previously and ten healthy volunteers of comparable age underwent 48-h polygraphic recording to assess the effects of wakefulness and sleep on beat-to-beat heart rate variability by means of power spectrum analysis.

Narratives of children with high-functioning autism spectrum disorder: A meta-analysis

Research in Developmental Disabilities, 2016
The aim of this meta-analysis was to analyze the narrative performance of children and adolescents with high-functioning Autism Spectrum Disorders (ASD) in terms of microstructure, macrostructure and internal state language.A systematic literature search yielded 24 studies that met the predetermined inclusion criteria.

Functional analysis of gut microbiota and immunoinflammation in children with autism spectrum disorders

Digestive and Liver Disease, 2019
Recent evidence implicates gut microbiota (GM) and immune alterations in autism spectrum disorders (ASD). We assess GM profile and peripheral levels of immunological, neuronal and bacterial molecules in ASD children and controls. Alarmin HMGB1 was explored as a non-invasive biomarker to monitor gastrointestinal (GI) symptoms.Thirty ASD children and 14 ...

Functional Analysis and Chained Schedule Treatment of Elopement in Teens with Autism Spectrum Disorder

Developmental Neurorehabilitation, 2023
Elopement is one of the most common forms of problem behavior for individuals with autism spectrum disorder (ASD) and is associated with the greatest probability of a lethal outcome. This study evaluated the effects of a function-based treatment package on elopement for two teenage boys with ASD who eloped frequently from caregivers.

Analysis and measurement of BAW devices with interdigital transducers. Application to spectrum analysis and delay function [PDF]

Proceedings of IEEE Ultrasonics Symposium ULTSYM-94, 1994
This paper deals with devices using InterDigital Transducers (IDT) for bulk wave generation and detection. A theoretical study of the coupling between IDT's deposited on two non parallel faces of a piezoelectric substrate has been carried out. This coupling has been characterized by the mutual admittance of the transducers.

A new window function for signal spectrum analysis and FIR filter design

2010 18th Iranian Conference on Electrical Engineering, 2010
A new window function is presented which like the well known Hamming window offers a preferred property for use in signal spectrum analysis: the sum of window coefficients with its shifted version by half of the order (50% overlap) is constant for the overlapped region in the time domain.

Analysis of disjoint decomposition of balanced Boolean functions through the Walsh spectrum

IEE Proceedings - Computers and Digital Techniques, 2001
Identification of disjunctive decomposition in a balanced Boolean function through Walsh spectra is performed. Balanced Boolean functions occur frequently in common logic circuits such as adders, parity checkers and multiplexers. Various types of decomposition of the balanced functions are considered and the corresponding Walsh spectral conditions that

Modulation transfer function analysis for a digitally spectrum-controllable light source

SPIE Proceedings, 2015
Owing to the ability of generating designated spectrums as special requirements, spectrum-controllable light source has attracted huge interesting in several fields, e.g. medical science, industrial detection, defense-related testing. In principle, optical performance of a spectrum-controllable light source can be predicted by some transfer functions ...
