Stochastic integrals in Riemann manifolds

open access: yesJournal of Multivariate Analysis, 1976
AbstractStochastic integrals are constructed with values in a compact Riemann manifold from a continuous martingale integrator that is given in the tangent space of the initial point of the stochastic integral and from a stochastic tensor field of linear endomorphisms of the tangent bundle.

Improving access to help with poor sleep across youth mental health services: Interim implementation and clinical outcomes

open access: yesBritish Journal of Clinical Psychology, EarlyView.
Abstract Objectives There is a high, unmet sleep need in young people with mental health difficulties. We took a whole‐system approach to improving access to sleep support across a youth mental health system (14–25 years). Methods We used the Exploration, Preparation, Implementation and Sustainment (EPIS) framework to develop an implementation ...

The futuristic manifolds of REM sleep

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Since one of its first descriptions 70 years ago, rapid eye movement sleep has continually inspired and excited new generations of sleep researchers. Despite significant advancements in understanding its neurocircuitry, underlying mechanisms and microstates, many questions regarding its function, especially beyond the early neurodevelopment ...

The genesis of the generalized Riemann integral

open access: yesComputers & Mathematics with Applications, 1995
This is a short history of the integral that inverts the ordinary derivative from the work of Denjoy and Perron to that of Henstock and Kurzweil; rather confusingly all aspects of this integral are called the generalized Riemann integral, a name usually reserved for the most recent developments.

Feasibility and usability of three consecutive nights with self‐applied, home polysomnography

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary In‐laboratory polysomnography, the gold‐standard for diagnosing sleep disorders, is resource‐demanding and not conducive to multiple night evaluations. Ambulatory polysomnography, especially when self‐applied, could be a viable alternative. This study aimed to assess the feasibility and reliability of self‐applied polysomnography over three ...

Profiling the sleep architecture of ageing adults using a seven‐state continuous‐time Markov model

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Sleep is a complex biological process regulated by networks of neurons and environmental factors. As one falls asleep, neurotransmitters from sleep–wake regulating neurones work in synergy to control the switching of different sleep states throughout the night. As sleep disorders or underlying neuropathology can manifest as irregular switching,

Barriers and Facilitators of Sleep Restriction Therapy in Internet‐Delivered CBT‐I: A Qualitative Content Analysis and the Development of a Treatment Path Model

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Sleep Restriction Therapy (SRT) is a core component of cognitive behavioural therapy for insomnia (CBT‐I). Yet, adherence to SRT can be a major challenge for patients. As this challenge is evident in conventional face‐to‐face therapy, it raises the question of adherence to SRT in internet‐delivered therapy.
