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 ...

One Single Session to Sleep Them All? The Potential of Single‐Session Interventions for Insomnia

Journal of Sleep Research, EarlyView.
ABSTRACT Poor sleep and insomnia are pervasive public health concerns, with insomnia ranking as the second most prevalent mental health disorder in the general population. Moreover, insomnia is a significant predictor of subsequent depression and is frequently co‐occurring with other psychological difficulties.

The Effects of Daridorexant on Patients With Comorbid Insomnia Disorder and Untreated Mild Obstructive Sleep Apnoea: A Post Hoc Subgroup Analysis of a Phase 3, Randomised Clinical Trial

Journal of Sleep Research, EarlyView.
ABSTRACT Daridorexant, a dual orexin receptor antagonist, is approved for the treatment of insomnia disorder in adults. Approximately 30%–35% of patients with insomnia disorder also have obstructive sleep apnoea (OSA) of any severity. It is unclear whether sleep medications provide safe and effective treatment for insomnia in these patients.

100% of the zeros of the Riemann zeta-function are on the critical line

, 2019
We consider a specific family of analytic functions $g_{\alpha,T}(s)$, satisfying certain functional equations and approximating to linear combinations of the Riemann zeta-function and its derivatives of the form $c_0\zeta(s)+c_1\frac{\zeta'(s)}{\log T}

Rest‐Activity Rhythms and Cognition in Older Adults With and Without Insomnia

Journal of Sleep Research, EarlyView.
ABSTRACT Insomnia is associated with risk for cognitive deficits. However, the literature assessing cognitive impairments in insomnia is replete with conflicting findings; it is unclear whether individuals with insomnia exhibit impaired cognition or whether specific sleep features consistently predict cognitive performance in insomnia.

Excessive Daytime Sleepiness Should Be Systematically Assessed in Individuals With Insomnia: A Population‐Based Study Employing a Virtual Agent‐Based Digital Tool

Journal of Sleep Research, EarlyView.
In a cohort of 21,590 participants undergoing a 17‐day digital sleep intervention, the ‘sleepy insomniac’ phenotype was highly prevalent and was associated with comorbidities in about half of the cases. Compared to individuals with insomnia without sleepiness, these participants were more likely to experience middle or late insomnia symptoms but showed

Digital App Based Cognitive Behaviour Therapy CBT‐I Course Improving Insomnia and Sleep Hygiene: A Randomised Controlled Trial

Journal of Sleep Research, EarlyView.
ABSTRACT Problems with initiating and maintaining sleep are among the most common health complaints, with prevalence rates exceeding 50% depending on the survey. Preventing the progression to chronic insomnia may reduce public healthcare costs and prevent secondary illnesses.

Spectral spacing correlations for chaotic and disordered systems

, 2000
New aspects of spectral fluctuations of (quantum) chaotic and diffusive systems are considered, namely autocorrelations of the spacing between consecutive levels or spacing autocovariances.
