Spectral and network investigation reveals distinct power and connectivity patterns between phasic and tonic REM sleep

Author(s): Avigdor T; Peter-Derex L; Ho A; Schiller K; Wang Y; Abdallah C; Delaire E; Jaber K; Travnicek V; Grova C; Frauscher B;

Although rapid eye movement (REM) sleep is often thought of as a singular state, it consists of two substates, phasic and tonic REM, defined by the presence (respectively absence) of bursts of rapid eye movements. These two substates have distinct EEG signatures and functional properties. However ...

Leveraging Personal Technologies in the Treatment of Schizophrenia Spectrum Disorders: Scoping Review

Author(s): D' Arcey J; Torous J; Asuncion TR; Tackaberry-Giddens L; Zahid A; Ishak M; Foussias G; Kidd S;

Background: Digital mental health is a rapidly growing field with an increasing evidence base due to its potential scalability and impacts on access to mental health care. Further, within underfunded service systems, leveraging personal technologies to deliver or support specialized service deliv ...

Assessment of Autism Spectrum Disorders in Children with Visual Impairment and Blindness: A Scoping Review

Author(s): Moire Stevenson

There is a higher incidence of diagnosed Autism Spectrum Disorder (ASD) in children with visual impairment and blindness (VIB) than in typically sighted children. However, we currently lack appropriate assessment measures to fully understand the neurodevelopment of children with VIB. Numerous factors, such as common characteristics between children with V ...

Ecological strategies of (pl)ants: Towards a world-wide worker economic spectrum for ants

Author(s): Gibb H; Bishop TR; Leahy L; Parr CL; Lessard JP; Sanders NJ; Shik JZ; Ibarra-Isassi J; Narendra A; Dunn RR; Wright IJ;

Current global challenges call for a rigorously predictive ecology. Our understanding of ecological strategies, imputed through suites of measurable functional traits, comes from decades of work that largely focussed on plants. However, a key question is whether plant ecological strategies resemb ...

Nonlinear Statistical Analysis of Normal and Pathological Infant Cry Signals in Cepstrum Domain by Multifractal Wavelet Leaders

Author(s): Lahmiri S; Tadj C; Gargour C;

Multifractal behavior in the cepstrum representation of healthy and unhealthy infant cry signals is examined by means of wavelet leaders and compared using the Student t-test. The empirical results show that both expiration and inspiration signals exhibit clear evidence of multifractal properties under healthy and unhealthy conditions. In addition, expira ...

In utero Exposure to Valproic-Acid Alters Circadian Organisation and Clock-Gene Expression: Implications for Autism Spectrum Disorders

Author(s): Ferraro S; de Zavalia N; Belforte N; Amir S;

Autism Spectrum Disorder (ASD) is a pervasive neurodevelopmental disorder characterised by restrictive patterns of behaviour and alterations in social interaction and communication. Up to 80% of children with ASD exhibit sleep-wake cycle disturbances, emphasising the pressing need for novel approaches in the treatment of ASD-associated comorbidities. Whil ...

Naïve Theories of Biology, Physics, and Psychology in Children with ASD.

Author(s): Poulin-Dubois D, Dutemple E, Burnside K

Theory of mind is defined as the understanding that mental states predict and explain people's behaviors. It develops around the age of 4 but seems to remain deficient in people with ASD, whereas other forms of naïve understanding remain intact. This study compares children with ASD to neurotypical children on tasks measuring naïve psychology, physics ...

Diagonalization of the finite Hilbert transform on two adjacent intervals: the Riemann-Hilbert approach

Author(s): Bertola M; Blackstone E; Katsevich A; Tovbis A;

In this paper we study the spectra of bounded self-adjoint linear operators that are related to finite Hilbert transforms H L : L 2 ( [ b L , 0 ] ) → L 2 ( [ 0 , b R ] ) and H R : L 2 ( [ 0 , b R ] ) → L 2 ( [ b L , 0 ] ) . These operators arise when one studies the interior problem of tomography. The diagonalization of H R , H L ha ...
