Functional singular spectrum analysis [PDF]

Stat, 2021
In this paper, we develop a new extension of the singular spectrum analysis (SSA) called functional SSA to analyze functional time series. The new methodology is constructed by integrating ideas from functional data analysis and univariate SSA. Specifically, we introduce a trajectory operator in the functional world, which is equivalent to the ...

Identification and Functional Analysis of Long Non-coding RNAs in Autism Spectrum Disorders [PDF]

Frontiers in Genetics, 2020
Genetic and environmental factors, alone or in combination, contribute to the pathogenesis of autism spectrum disorder (ASD). Although many protein-coding genes have now been identified as disease risk genes for ASD, a detailed illustration of long non ...

Cerebellar dysconnectivity in schizophrenia spectrum: task-based functional connectivity analysis and cognitive stratification [PDF]

Frontiers in Psychiatry
IntroductionSchizophrenia is conceptualized as a disorder of brain network dysconnectivity, yet relationships between neural alterations, cognitive deficits, and genetic risk remain unclear.MethodsWe examined 86 participants: schizophrenia patients (SCZ),

Density Functional Theory Analysis of Luteolin Molecular Structure and Spectrum

ACS Omega
Luteolin is a natural flavonoid compound. Numerous studies have demonstrated that luteolin exhibits pharmacological activities such as antioxidant and antitumor effects; however, the molecular mechanisms linking its electronic structure to pharmacological activities have not been systematically elucidated.

Dynamic Functional Network Connectivity Analysis in Autism Spectrum Disorder: An EEG Study

IEEE Access
Convergent evidence has suggested a significant effect of bumetanide exposure on brain connectivity in patients with autism spectrum disorder (ASD), yet the characteristics of favorable treatment outcome remains largely unknown. In this work, we aimed to

The spectrum of functional neurological disorders: A retrospective analysis at a tertiary hospital in South Africa

South African Journal of Psychiatry, 2021
Background: Functional neurological disorders (FNDs) are commonly encountered in practice; however, there is a paucity of data in Africa. Aim: To identify and describe the clinical profile of patients presenting with FNDs, underlying medical and ...

Autism spectrum disorders: a meta-analysis of executive function [PDF]

Molecular Psychiatry, 2017
Evidence of executive dysfunction in autism spectrum disorders (ASD) across development remains mixed and establishing its role is critical for guiding diagnosis and intervention. The primary objectives of this meta-analysis is to analyse executive function (EF) performance in ASD, the fractionation across EF subdomains, the clinical utility of EF ...

Functional time series forecasting: Functional singular spectrum analysis approaches

Stat, 2023
AbstractWe introduce two novel nonparametric forecasting methods designed for functional time series (FTS), namely, functional singular spectrum analysis (FSSA) recurrent and vector forecasting. Our algorithms rely on extracted signals obtained from the FSSA method and innovative recurrence relations to make predictions. These techniques are model‐free,
