Emboli detection during continuous-wave doppler sonography of internal carotid artery stenosis.

Journal of stroke and cerebrovascular diseases : the official journal of National Stroke Association

Klötzsch C, Popescu O.
PMID: 17895067
J Stroke Cerebrovasc Dis. 1998 Mar-Apr;7(2):109-12. doi: 10.1016/s1052-3057(98)80137-7.

BACKGROUND AND PURPOSE: Continuous-wave (cw)-Doppler sonography is a wellestablished noninvasive method for examining the extracranial vessels. It is extremely rare for an acute ischemic event to occur during cw-Doppler sonography of carotid stenosis. However, no data are available concerning...

A Novel Effect in Phycomyces Phototropism : Positive Bending and Compensation Spectrum in Far UV.

Plant physiology

Popescu T, Roessler A, Fukshansky L.
PMID: 16667221
Plant Physiol. 1989 Dec;91(4):1586-93. doi: 10.1104/pp.91.4.1586.

A novel effect-positive phototropic bending under far UV irradiation (between 260 and 305 nanometers) at low intensities-is reported. Natural compensation points (intensities which cause no bending under unilateral irradiation) have been determined for different wavelengths. The curve connecting these...

Mechanics versus thermodynamics: swelling in multiple-temperature-sensitive core-shell microgels.

Angewandte Chemie (International ed. in English)

Spin reorientation and structural relaxation of atomic layers: pushing the limits of accuracy.

Physical review letters

Meyerheim HL, Sander D, Popescu R, Kirschner J, Robach O, Ferrer S.
PMID: 15524908
Phys Rev Lett. 2004 Oct 08;93(15):156105. doi: 10.1103/PhysRevLett.93.156105. Epub 2004 Oct 08.

The correlation between an ad-layer-induced spin reorientation transition (SRT) and the ad-layer-induced structural relaxation is investigated by combined in situ surface x-ray diffraction and magneto-optical Kerr-effect experiments on Ni/Fe/Ni(111) layers on W(110). The Fe-induced SRT from in-plane to out-of-plane,...

Proposal for energy-time entanglement of quasiparticles in a solid-state device.

Physical review letters

Scarani V, Gisin N, Popescu S.
PMID: 15169260
Phys Rev Lett. 2004 Apr 23;92(16):167901. doi: 10.1103/PhysRevLett.92.167901. Epub 2004 Apr 23.

We present a proposal for the experimental observation of energy-time entanglement of quasiparticles in mesoscopic physics. This type of entanglement arises whenever correlated particles are produced at the same time and this time is uncertain in the sense of...

Intense gamma-ray source in the giant-dipole-resonance range driven by 10-TW laser pulses.

Physical review letters

Giulietti A, Bourgeois N, Ceccotti T, Davoine X, Dobosz S, D'Oliveira P, Galimberti M, Galy J, Gamucci A, Giulietti D, Gizzi LA, Hamilton DJ, Lefebvre E, Labate L, Marquès JR, Monot P, Popescu H, Réau F, Sarri G, Tomassini P, Martin P.
PMID: 18851220
Phys Rev Lett. 2008 Sep 05;101(10):105002. doi: 10.1103/PhysRevLett.101.105002. Epub 2008 Sep 03.

A gamma-ray source with an intense component around the giant dipole resonance for photonuclear absorption has been obtained via bremsstrahlung of electron bunches driven by a 10-TW tabletop laser. 3D particle-in-cell simulation proves the achievement of a nonlinear regime...

Diffraction phase and fluorescence microscopy.

Optics express

Park Y, Popescu G, Badizadegan K, Dasari RR, Feld MS.
PMID: 19529201
Opt Express. 2006 Sep 04;14(18):8263-8. doi: 10.1364/oe.14.008263.

We have developed diffraction phase and fluorescence (DPF) microscopy as a new technique for simultaneous quantitative phase imaging and epi-fluorescence investigation of live cells. The DPF instrument consists of an interference microscope, which is incorporated into a conventional inverted...

The general pinhole camera: effective and efficient nonuniform sampling for visualization.

IEEE transactions on visualization and computer graphics

Popescu V, Rosen P, Arns L, Tricoche X, Wyman C, Hoffmann CM.
PMID: 20616393
IEEE Trans Vis Comput Graph. 2010 Sep-Oct;16(5):777-90. doi: 10.1109/TVCG.2010.22.

We introduce the general pinhole camera (GPC), defined by a center of projection (i.e., the pinhole), an image plane, and a set of sampling locations in the image plane. We demonstrate the advantages of the GPC in the contexts...

Cumulative gene and chromosome alterations associated with in-vitro neoplastic transformation of human cervical cells.
