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 ...

Autonomic function in narcolepsy: power spectrum analysis of heart rate variability
Journal of Neurology, 1997Ten 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.

Analysis of the Photodetector Array Spectrum Using the Influence Function
Russian Microelectronics, 2001The conversion of an optical image to a carrier flow in the semiconductor substrate of a photodetector array is accomplished using the Green function method. Asymptotic solutions for large and small arguments are analyzed. Among them are intermediate asymptotic self-similar solutions that are suitable for the transition to the spectral range.

Sigmoid Approximation to the Gaussian $Q$-function and its Applications to Spectrum Sensing Analysis
2019 IEEE Wireless Communications and Networking Conference (WCNC), 2019Most of the existing approximations for the Gaussian $Q$ -function have been developed bearing in mind applications that require high estimation accuracy for large argument values (e.g., derivation of the bit/symbol error rates of digital communication systems, which are typically in the order of 10−6to 10−12).

IMA Journal of Mathematical Control and Information, 2011
A singularly perturbed linear functional-differential system is considered. The delay is assumed to be small of the order of a small parameter multiplying a part of derivatives in the system. It is ‘not assumed that the fast subsystem is asymptotically stable’.

Diffusion Time Spectrum Analysis Observation of Aquaporin Functional Dynamics
ISMRM Annual MeetingThe function of water molecule exchange on the plasma membrane by aquaporins was evaluated using HEK293T cultured cells. Time-dependent diffusion magnetic resonance imaging (MRI), in which diffusion time (DT) was varied in 14 steps from 13 to 784 ms, was used to observe differences in water molecules and the permeability of the cell membrane with and ...

Cerebral Cortex
Abstract Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by social and behavioral impairments, emerging in early childhood with unclear causes. The primary aim of this study is to investigate shifts in the functional gradients underlying hierarchical brain network organization in ASD and to assess their potential ...

A Functional Analysis of Sharing in Preschoolers with Autism Spectrum Disorder
Individuals with autism spectrum disorder (ASD) demonstrate deficits in social behavior which may hinder them from engaging in social interactions. Results of descriptive analyses suggest that children who engage in prosocial behaviors, such as sharing, likely receive social positive reinforcement from peers in the form of attention.openaire +2 more sources
