Crystal structure and properties of barium thorate BaThO$_3$ from first principles

open access: yes, 2013
The phonon spectrum of cubic BaThO$_3$ with the perovskite structure is calculated from first principles within the density functional theory. The analysis of unstable modes in the phonon spectrum enables to determine the symmetry of all possible ...

Functional Bethe ansatz methods for the open XXX chain

open access: yes, 2010
We study the spectrum of the integrable open XXX Heisenberg spin chain subject to non-diagonal boundary magnetic fields. The spectral problem for this model can be formulated in terms of functional equations obtained by separation of variables or ...

Scaling properties of the redshift power spectrum: theoretical models [PDF]

open access: yes, 2000
We report the results of an analysis of the redshift power spectrum $P^S(k,\mu)$ in three typical Cold Dark Matter (CDM) cosmological models, where $\mu$ is the cosine of the angle between the wave vector and the line-of-sight.

Genomic and Functional Analysis of Emerging Virulent and Multidrug-Resistant Escherichia coli Lineage Sequence Type 648

open access: yesAntimicrobial Agents and Chemotherapy, 2019
The pathogenic extended-spectrum-beta-lactamase (ESBL)-producing Escherichia coli lineage ST648 is increasingly reported from multiple origins. Our study of a large and global ST648 collection from various hosts (87 whole-genome sequences) combining core

Dynamic Functional Network Connectivity Analysis in Autism Spectrum Disorder: An EEG Study

open access: yesIEEE Access
Convergent evidence has suggested a significant effect of bumetanide exposure on brain connectivity in patients with autism spectrum disorder (ASD), yet the characteristics of favorable treatment outcome remains largely unknown. In this work, we aimed to

Disrupted Dynamic Functional Connectivity in Distinguishing Subjective Cognitive Decline and Amnestic Mild Cognitive Impairment Based on the Triple-Network Model

open access: yesFrontiers in Aging Neuroscience, 2021
Background: Subjective cognitive decline and amnestic mild cognitive impairment (aMCI) were widely thought to be preclinical AD spectrum disorders, characterized by aberrant functional connectivity (FC) within the triple networks of the default mode ...

Conserving and Gapless Approximations for an Inhomogeneous Bose Gas at Finite Temperatures

open access: yes, 1996
We derive and discuss the equations of motion for the condensate and its fluctuations for a dilute, weakly interacting Bose gas in an external potential within the self--consistent Hartree--Fock--Bogoliubov (HFB) approximation.

Hard to "tune in": neural mechanisms of live face-to-face interaction with high-functioning autistic spectrum disorder [PDF]

open access: yes, 2012
Persons with autism spectrum disorders (ASD) are known to have difficulty in eye contact (EC). This may make it difficult for their partners during face to face communication with them. To elucidate the neural substrates of live inter-subject interaction

Abnormal Functional Connectivity of Resting State Network Detection Based on Linear ICA Analysis in Autism Spectrum Disorder

open access: yesFrontiers in Physiology, 2018
Some functional magnetic resonance imaging (fMRI) researches in autism spectrum disorder (ASD) patients have shown that ASD patients have significant impairment in brain response.

Radiological and functional lung sequelae of COVID-19: a systematic review and meta-analysis

open access: yesBMC Pulmonary Medicine, 2021
Background The coronavirus disease 2019 (COVID-19) causes a wide spectrum of lung manifestations ranging from mild asymptomatic disease to severe respiratory failure. We aimed to clarify the characteristics of radiological and functional lung sequelae of
