A Variational Stereo Method for the Three-Dimensional Reconstruction of Ocean Waves [PDF]

open access: yes, 2011
We develop a novel remote sensing technique for the observation of waves on the ocean surface. Our method infers the 3-D waveform and radiance of oceanic sea states via a variational stereo imagery formulation.

Dynamic time warping outperforms Pearson correlation in detecting atypical functional connectivity in autism spectrum disorders

open access: yesNeuroImage, 2020
Resting state fMRI (rsfMRI) is frequently used to study brain function, including in clinical populations. Similarity of blood-oxygen-level-dependent (BOLD) fluctuations during rsfMRI between brain regions is thought to reflect intrinsic functional ...

Synthesis, spectroscopic characterization, X-ray structure, and DFT calculations of some new 1,4-dihydro-2,6-dimethyl-3,5-pyridinedicarboxamides. [PDF]

open access: yesPLoS ONE, 2014
A series of novel 1,4-dihydro-2,6- dimethyl-3,5-pyridinedicarboxamides were synthesized and characterized by infrared absorption spectrum (IR), proton nuclear magnetic resonance (1H NMR), elemental analysis, ultraviolet spectrum (UV), and fluorescence ...

Developmental Meta-Analysis of the Functional Neural Correlates of Autism Spectrum Disorders [PDF]

open access: yesJournal of the American Academy of Child & Adolescent Psychiatry, 2013
There is a pressing need to elucidate the brain-behavior interactions underlying autism spectrum disorders (ASD) given the marked rise in ASD diagnosis over the past decade. Functional magnetic resonance imaging (fMRI) has begun to address this need, but few fMRI studies have evaluated age-related changes in ASD. Therefore, we conducted a developmental

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

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.

A meta-analysis comparing cognitive function across the mood/psychosis diagnostic spectrum [PDF]

open access: yesPsychological Medicine, 2020
AbstractBackgroundThe nature and degree of cognitive impairments in schizoaffective disorder is not well established. The aim of this meta-analysis was to characterise cognitive functioning in schizoaffective disorder and compare it with cognition in schizophrenia and bipolar disorder.

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 ...

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 ...

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 ...
