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

Journal 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 ...

Linear law for the logarithms of the Riemann periods at simple critical zeta zeros [PDF]

, 2006
Each simple zero 1/2 + iγn of the Riemann zeta function on the critical line with γn > 0 is a center for the flow s˙ = ξ(s) of the Riemann xi function with an associated period Tn. It is shown that, as γn →∞, log Tn ≥ π/4 γn + O(log γn).

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

Journal 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,

Phenotypic Variability in Slow‐Wave Sleep in Depression: Associations With Clinical Profiles and Disorder Severity

Journal of Sleep Research, EarlyView.
ABSTRACT Slow‐wave sleep (SWS; stage N3) is often reported as reduced in depression, yet variability across depressive phenotypes remains poorly characterised. This study aimed to determine whether N3 architecture—proportion, duration, and latency—identifies clinically distinct profiles in major depressive episode (MDE).

Prescription of Psychotropic Drugs for Chronic Insomnia in Primary Care

Journal of Sleep Research, EarlyView.
ABSTRACT Insomnia is the most prevalent sleep disorder in adults, representing a major public health problem. Healthcare management in a specific area first requires analysing its current practices and issues. We conducted a retrospective observational study of over 100,000 patients from two large primary care databases in the public healthcare ...

Risks Associated With Benzodiazepine Long‐Term Use in Chronic Insomnia: A Systematic Review and (Network) Meta‐Analysis

Journal of Sleep Research, EarlyView.
ABSTRACT This systematic literature review evaluated the risks of using benzodiazepine medications for more than 3 months in adults with chronic insomnia. Chronic insomnia is defined as ongoing dissatisfaction with sleep quantity or quality, causing significant distress and impaired functioning during the day.

Lights On or Off? The Efficacy of Light Therapy as Add‐On to Cognitive Behavioural Therapy for Insomnia—A Pilot Study

Journal of Sleep Research, EarlyView.
ABSTRACT Cognitive behavioural therapy for insomnia (CBT‐I) is recommended as first‐line treatment for insomnia disorder. However, around 25% of the patients do not respond to the treatment, and only 40% achieve full remission. The current study investigates the therapeutic potential of light therapy as an add‐on to CBT‐I.

SOC-Based Simulation of 3D MIMO Mobile-to-Mobile Fading Channels: A Riemann Sum Approach

IEEE Open Journal of Vehicular Technology
The Riemann sum method (RSM) was introduced almost two decades ago as an efficient parameter computation method for the design of narrowband multiple-input multiple-output (MIMO) mobile fading channel simulators based on the sum-of-cisoids (SOC ...
