Variational Bayesian causal connectivity analysis for fMRI.

Frontiers in neuroinformatics

Luessi M, Babacan SD, Molina R, Booth JR, Katsaggelos AK.
PMID: 24847244
Front Neuroinform. 2014 May 05;8:45. doi: 10.3389/fninf.2014.00045. eCollection 2014.

The ability to accurately estimate effective connectivity among brain regions from neuroimaging data could help answering many open questions in neuroscience. We propose a method which uses causality to obtain a measure of effective connectivity from fMRI data. The...

The formation mechanism of iron oxide nanoparticles within the microwave-assisted solvothermal synthesis and its correlation with the structural and magnetic properties.

Dalton transactions (Cambridge, England : 2003)

Kozakova Z, Kuritka I, Kazantseva NE, Babayan V, Pastorek M, Machovsky M, Bazant P, Saha P.
PMID: 26595518
Dalton Trans. 2015 Dec 28;44(48):21099-108. doi: 10.1039/c5dt03518j. Epub 2015 Nov 23.

Magnetic nanoparticles based on Fe3O4 were prepared by a facile and rapid one-pot solvothermal synthesis using FeCl3·6H2O as a source of iron ions, ethylene glycol as a solvent and NH4Ac, (NH4)2CO3, NH4HCO3 or aqueous NH3 as precipitating and nucleating...

The strong localization of surface plasmon polariton on a metal-coated tip of optical fiber.

Ultramicroscopy

Babayan AE, Nerkararyan KhV.
PMID: 17350171
Ultramicroscopy. 2007 Nov;107(12):1136-40. doi: 10.1016/j.ultramic.2007.01.009. Epub 2007 Feb 06.

It is shown that during the propagation of surface plasmon polariton (SPP) on a metal-coated tip of an optical fiber its wavelength essentially decreases and wave fields anomalously increase. Dependence of a degree of localization of SPP on sharpness...

Bayesian blind deconvolution from differently exposed image pairs.

IEEE transactions on image processing : a publication of the IEEE Signal Processing Society

Babacan SD, Wang J, Molina R, Katsaggelos AK.
PMID: 20529746
IEEE Trans Image Process. 2010 Nov;19(11):2874-88. doi: 10.1109/TIP.2010.2052263. Epub 2010 Jun 07.

Photographs acquired under low-lighting conditions require long exposure times and therefore exhibit significant blurring due to the shaking of the camera. Using shorter exposure times results in sharper images but with a very high level of noise. In this...

Compressive light field sensing.

IEEE transactions on image processing : a publication of the IEEE Signal Processing Society

Babacan SD, Ansorge R, Luessi M, Matarán PR, Molina R, Katsaggelos AK.
PMID: 22851261
IEEE Trans Image Process. 2012 Dec;21(12):4746-57. doi: 10.1109/TIP.2012.2210237. Epub 2012 Jul 25.

We propose a novel design for light field image acquisition based on compressive sensing principles. By placing a randomly coded mask at the aperture of a camera, incoherent measurements of the light passing through different parts of the lens...

Light- and electric-field-induced first-order orientation transitions in a dendrimer-doped nematic liquid crystal.

Physical review. E, Statistical, nonlinear, and soft matter physics

Babayan EA, Budagovsky IA, Shvetsov SA, Smayev MP, Zolot'ko AS, Boiko NI, Barnik MI.
PMID: 21230682
Phys Rev E Stat Nonlin Soft Matter Phys. 2010 Dec;82(6):061705. doi: 10.1103/PhysRevE.82.061705. Epub 2010 Dec 22.

Interaction of light and ac electric fields with a nematic liquid crystal (NLC) doped with nanosized second-generation carbosilane codendrimers containing terminal azobenzene fragments has been studied. A first-order Freedericksz transition in the linearly polarized light, accompanied by an intrinsic...

INTERVENTIONAL MRI WITH SPARSE SAMPLING USING UNION-OF-SUBSPACES.

IEEE transactions on bio-medical engineering

Babacan SD, Lam F, Peng X, Do MN, Liang ZP.
PMID: 25152538
IEEE Trans Biomed Eng. 2008;9:314-317. doi: 10.1109/ISBI.2012.6235547.

A significant problem in interventional magnetic resonance imaging is limited imaging speed. This paper addresses this problem using a new signal model known as union-of-subspaces. This model enables an effective use of sparse sampling and prior information to significantly...
