Functional Time Series Forecasting: Functional Singular Spectrum Analysis Approaches

open access: yes, 2020
In this paper, we propose two nonparametric methods used in the forecasting of functional time-dependent data, namely functional singular spectrum analysis recurrent forecasting and vector forecasting. Both algorithms utilize the results of functional singular spectrum analysis and past observations in order to predict future data points where ...

Axially Harmonic Functions and the Harmonic Functional Calculus on the S-spectrum [PDF]

open access: yesJournal of Geometric Analysis, 2022
The spectral theory on the S-spectrum was introduced to give an appropriate mathematical setting to quaternionic quantum mechanics, but it was soon realized that there were different applications of this theory, for example, to fractional heat diffusion ...

Dynamic time warping outperforms Pearson correlation in detecting atypical functional connectivity in autism spectrum disorders

open access: yesNeuroImage, 2020
Resting state fMRI (rsfMRI) is frequently used to study brain function, including in clinical populations. Similarity of blood-oxygen-level-dependent (BOLD) fluctuations during rsfMRI between brain regions is thought to reflect intrinsic functional ...

A Variational Stereo Method for the Three-Dimensional Reconstruction of Ocean Waves [PDF]

open access: yes, 2011
We develop a novel remote sensing technique for the observation of waves on the ocean surface. Our method infers the 3-D waveform and radiance of oceanic sea states via a variational stereo imagery formulation.

Multi-level analysis of the gut–brain axis shows autism spectrum disorder-associated molecular and microbial profiles

open access: yesNature Neuroscience, 2023
Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by heterogeneous cognitive, behavioral and communication impairments. Disruption of the gut–brain axis (GBA) has been implicated in ASD although with limited reproducibility ...

A meta-analysis comparing cognitive function across the mood/psychosis diagnostic spectrum [PDF]

open access: yesPsychological Medicine, 2020
AbstractBackgroundThe nature and degree of cognitive impairments in schizoaffective disorder is not well established. The aim of this meta-analysis was to characterise cognitive functioning in schizoaffective disorder and compare it with cognition in schizophrenia and bipolar disorder.
