The first order convergence law fails for random perfect graphs [PDF]

, 2018
We consider first order expressible properties of random perfect graphs. That is, we pick a graph $G_n$ uniformly at random from all (labelled) perfect graphs on $n$ vertices and consider the probability that it satisfies some graph property that can be ...

Chromospheric observations and magnetic configuration of a supergranular structure

, 2018
Unipolar magnetic regions are often associated with supergranular cells. The chromosphere above these regions is regulated by the magnetic field, but the field structure is poorly known.

Novel electrocardiographic criteria for the diagnosis of arrhythmogenic right ventricular cardiomyopathy [PDF]

, 2015
Aims: In order to improve the electrocardiographic (ECG) diagnosis of arrhythmogenic right ventricular cardiomyopathy (ARVC), we evaluated novel quantitative parameters of the QRS complex and the value of bipolar chest leads (CF leads) computed from the ...

Association of interleukin-10 levels with age of onset and duration of illness in patients with major depressive disorder

Brazilian Journal of Psychiatry, 2015
Objective:To investigate peripheral levels of interleukin-10 (IL-10) in patients with major depressive disorder (MDD) and bipolar disorder (BD) and evaluate the relationship between IL-10, age of disease onset, and duration of illness.Methods:Case ...

Generation of unipolar pulses in a circular Raman-active medium excited by few-cycle optical pulses

, 2016
We study theoretically a new possibility of unipolar pulses generation in Raman-active medium excited by a series of few-cycle optical pulses. We consider the case when the Raman-active particles are uniformly distributed along the circle, and ...

Magnetic Interaction in Ultra-compact Binary Systems

, 2009
This article reviews the current works on ultra-compact double-degenerate binaries in the presence of magnetic interaction, in particular, unipolar induction. The orbital dynamics and evolution of compact white-dwarf pairs are discussed in detail. Models

Detection of endo-epicardial atrial low-voltage areas using unipolar and omnipolar voltage mapping

Frontiers in Physiology, 2022
Background: Low-voltage areas (LVA) can be located exclusively at either the endocardium or epicardium. This has only been demonstrated for bipolar voltages, but the value of unipolar and omnipolar voltages recorded from either the endocardium and ...

Numerical methodology to evaluate unipolar saturation current limit of DC corona discharge in complex geometries

Scientific Reports, 2022
The unipolar saturation current limit ( $${I}_{sat}$$ I sat ) gives an upper limit to the corona current that can be obtained from a unipolar corona discharge.

Unipolar and bipolar fatigue in antiferroelectric lead zirconate thin films and evidences for switching-induced charge injection inducing fatigue

, 2010
For the first time, we show that unipolar fatigue does occur in antiferroelectric capacitors, confirming the predictions of a previous work [Appl. Phys. Lett., 94, 072901 (2009)].

Photoacoustic generation of focused quasi-unipolar pressure pulses [PDF]

, 2010
The photoacoustic effect was employed to generate short-duration quasi-unipolar acoustic pressure pulses in both planar and spherically focused geometries.
