A Bayesian approach to phase angles
, 2023 This presentation describes a Bayesian approach to the analysis of phase angles using an example neurolinguistic dataset. Posterior sampling was performed with the software Stan; this is also the syntax of any example code.

Determinants of bioelectrical phase angle in disease [PDF]
British Journal of Nutrition, 2011 Phase angle (PhA), a parameter of bioelectrical impedance analysis, is a well-known predictor of morbidity and mortality in various diseases. The causes of decreased PhA are, however, not yet completely understood. We therefore investigated determinants of PhA in 777 hospitalised patients in a retrospective analysis.

Association between phase angle and coronary artery calcium score in patients on peritoneal dialysis
Frontiers in Nutrition, 2022 IntroductionThe phase angle (PhA) has been used as a nutritional marker and predictor of mortality in patients on peritoneal dialysis (PD). The coronary artery calcium (CAC) score has shown to predict the incidence of acute myocardial infarction and ...

Adiabatic Berry Phase and Hannay Angle for Open Paths [PDF]
Annals Phys.270:178-197,1998, 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-path Hannay angle, we establish a connection between the open-path Berry phase and Hannay angle by ...

IEEE Transactions on Power Delivery, 2020 Timestamp Shift (TS) in synchrophasor data can lead to false operation of synchrophasor-based wide-area monitoring, protection and control applications. The letter presents a method to detect TS of synchrophasor data based on similarity analysis between ...

The effect of flexibility and bend angle on the phase diagram of hard colloidal boomerangs [PDF]
Molecular Physics, 2018, 2018 We study the effect of flexibility and bend angle on systems of hard semiflexible boomerangs. These are modelled as two rodlike segments joined at one end with an angle that can fluctuate about a preferred angle. We use a second-virial theory for semiflexible chains with two segments, and numerically solve for the full orientation distribution function

Angle-Dependent Phase Shifter Model for Reconfigurable Intelligent Surfaces: Does the Angle-Reciprocity Hold? [PDF]
, 2020 The existing phase shifter models adopted for reconfigurable intelligent surfaces (RISs) have ignored the electromagnetic (EM) waves propagation behavior, thus cannot reveal practical effects of RIS on wireless communication systems. Based on the equivalent circuit, this paper introduces an angle-dependent phase shifter model for varactor-based RISs ...

Journal of Functional Morphology and Kinesiology, 2020 Purpose: Bioimpedance data through bioimpedance vector analysis (BIVA) is used to evaluate cellular function and body fluid content. This study aimed to (i) identify whether BIVA patters differ according to the competitive period and (ii) provide ...
