Right ventricular outflow tract velocity time integral-to-pulmonary artery systolic pressure ratio: a non-invasive metric of pulmonary arterial compliance differs across the spectrum of pulmonary hypertension. [PDF]

open access: yes, 2019
Pulmonary arterial compliance (PAC), invasively assessed by the ratio of stroke volume to pulmonary arterial (PA) pulse pressure, is a sensitive marker of right ventricular (RV)-PA coupling that differs across the spectrum of pulmonary hypertension (PH ...

Signatures of confinement in Landau gauge QCD [PDF]

open access: yes, 2004
We summarise an analysis of the infrared regime of Landau gauge QCD by means of a flow equation approach. The infrared behaviour of gluon and ghost propagators is evaluated. The results provide further evidence for the Kugo-Ojima confinement scenario. We

Sex Differences in the Default Mode Network with Regard to Autism Spectrum Traits: A Resting State fMRI Study.

open access: yesPLoS ONE, 2015
Autism spectrum traits exist on a continuum and are more common in males than in females, but the basis for this sex difference is unclear. To this end, the present study draws on the extreme male brain theory, investigating the relationship between sex ...

Time-Dependent Magnons from First Principles [PDF]

open access: yes, 2020
We propose an efficient and non-perturbative scheme to compute magnetic excitations for extended systems employing the framework of time-dependent density functional theory.

Evaluation of renal allograft function by Doppler spectrum analysis A preliminary study

open access: yesTransplant International, 1989
A decreased renal function is rather common after renal transplantation. The causes of this decreased function are diverse and difficult to differentiate. Yet, duplex examination, and especially quantitative Doppler spectrum analysis of the blood velocities in the renal artery, may be an effective method for differentiating between some of these causes.

Loss of Wdfy3 in mice alters cerebral cortical neurogenesis reflecting aspects of the autism pathology. [PDF]

open access: yes, 2014
Autism spectrum disorders (ASDs) are complex and heterogeneous developmental disabilities affecting an ever-increasing number of children worldwide. The diverse manifestations and complex, largely genetic aetiology of ASDs pose a major challenge to the ...

A META-ANALYSIS OF FUNCTIONAL PROSODY IN AUTISM SPECTRUM DISORDER

open access: yes, 2023
Autism is a neurodevelopmental disorder characterized by atypical interests, body movements, social interactions and language (American Psychiatric Association, 2013). Autism spectrum disorders (ASD) are common, with the current estimate of the prevalence of ASD births in the United States being 1 in 54 (Maenner et al., 2020).

Analysis of the biological spectrum of vascular flora of Ravni Srem flood forests [PDF]

open access: yesGlasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2011
One of the essential analyses performed during the floristic study of a region is the analysis of the biological spectrum. The analysis of the biological spectrum of the flora includes the determination of the type of life form for each taxon ...

The Finite Size SU(3) Perk-Schultz Model with Deformation Parameter q=exp(i 2 pi/3) [PDF]

open access: yes, 2002
From extensive numeric diagonalizations of the SU(3) Perk-Schultz Hamiltonian with a special value of the anisotropy and different boundary conditions, we have observed simple regularities for a significant part of its eigenspectrum.

APPROXIMATION OF THE INTEGRAL ENERGY SPECTRUM OF PROTONS OF SCR IN THE RANGE OF > 1-850 MEV

open access: yesOdessa Astronomical Publications, 2019
This work is a continuation of the work (Isaeva E., 2018) in which a new approximation of the in- tegral energy spectrum of solar cosmic ray (SCR) protons was presented in the range > 1-100 MeV. In this work, the comments and wishes of colleagues working
