Circadian Phase and Phase Angle Disorders in Primary Insomnia [PDF]
Sleep, 2017 We aimed to identify the prevalence of circadian phase and phase angle abnormalities in patients with insomnia.We conducted a cross-sectional, multicenter study at three sleep laboratories in the United States and Australia. Patients with insomnia and healthy control participants completed a sleep log for 7 days.

A Second Look at Masses and Mixings of Quarks and Leptons [PDF]
, 1997 The masses of quarks and leptons in units of $m_t$ are expressed in powers of $\sigma=\sqrt{m_c/m_t}$. The regularities found suggest specific mass matrices. They reproduce all masses and mixings in striking agreement with observation.

Parametric Study of an Air Charged Franchot Engine with Novel Hot and Cold Isothermalizers
Inventions, 2017 The Stirling engine is an external combustion engine that uses heat exchangers to enhance the addition and removal of energy. This makes the engine power-dense but expensive, less efficient and complicated. In this contribution, the Stirling engine based

Adiabatic Berry Phase and Hannay Angle for Open Paths
, 1998 We obtain the adiabatic Berry phase by defining a generalised gauge potential whose line integral gives the phase holonomy for arbitrary evolutions of parameters. Keeping in mind that for classical integrable systems it is hardly clear how to obtain open-

Journal of Clinical Medicine, 2020 Malnutrition is associated with sarcopenia, cachexia, and prognosis. We investigated the usefulness of phase angle (PhA) as a marker of sarcopenia, cachexia, and malnutrition in 412 hospitalized patients with cardiovascular disease.

The density in the density of states method
, 2013 It has been suggested that for QCD at finite baryon density the distribution of the phase angle, i.e. the angle defined as the imaginary part of the logarithm of the fermion determinant, has a simple Gaussian form.

Phase Angle Spatial Embedding (PhASE)
, 2018 Modern resting-state functional magnetic resonance imaging (rs-fMRI) provides a wealth of information about the inherent functional connectivity of the human brain. However, understanding the role of negative correlations and the nonlinear topology of rs-fMRI remains a challenge. To address these challenges, we propose a novel graph embedding technique,

Journal of the International Society of Sports Nutrition, 2019 Background Raw bioelectrical values can be used to assess physiological outcomes, though limited information is available concerning the relationships between changes in these values and changes in other variables of interest.

Mutual phase-locking in high frequency microwave nanooscillators as function of field angle
, 2008 We perform a qualitative analysis of phase locking in a double point-contact spinvalve system by solving the Landau-Lifshitz-Gilbert-Slonzewski equation using a hybrid-finite-element method. We show that the phase-locking behaviour depends on the applied
