Risk Factors for Urinary Retention Following Surgical Repair of Hip Fracture in Female Patients.

Geriatric orthopaedic surgery & rehabilitation

Cialic R, Shvedov V, Lerman Y.
PMID: 28255510
Geriatr Orthop Surg Rehabil. 2017 Mar;8(1):39-43. doi: 10.1177/2151458516683507. Epub 2016 Dec 21.

BACKGROUND/OBJECTIVES: Postoperative urinary retention (POUR) is a common event following surgical procedures. An increase in the number of elderly individuals who undergo hip fracture repair procedures is inevitable due to the aging of population. Postoperative urinary retention is associated...

Physical review letters

Shiloh R, Tsur Y, Remez R, Lereah Y, Malomed BA, Shvedov V, Hnatovsky C, Krolikowski W, Arie A.
PMID: 25793830
Phys Rev Lett. 2015 Mar 06;114(9):096102. doi: 10.1103/PhysRevLett.114.096102. Epub 2015 Mar 04.

New forms of electron beams have been intensively investigated recently, including vortex beams carrying orbital angular momentum, as well as Airy beams propagating along a parabolic trajectory. Their traits may be harnessed for applications in materials science, electron microscopy,...

Visualizing polarization singularities in Bessel-Poincaré beams.

Shvedov V, Karpinski P, Sheng Y, Chen X, Zhu W, Krolikowski W, Hnatovsky C.
PMID: 25969330
Opt Express. 2015 May 04;23(9):12444-53. doi: 10.1364/OE.23.012444.

We demonstrate that an annulus of light whose polarization is linear at each point, but the plane of polarization gradually rotates by π radians can be used to generate Bessel-Poincaré beams. In any transverse plane this beam exhibits concentric...

Dynamics of optical spin-orbit coupling in uniaxial crystals.

Optics letters

Brasselet E, Izdebskaya Y, Shvedov V, Desyatnikov AS, Krolikowski W, Kivshar YS.
PMID: 19340206
Opt Lett. 2009 Apr 01;34(7):1021-3. doi: 10.1364/ol.34.001021.

We study theoretically and verify experimentally the detailed dynamics of spin-to-orbital angular momentum conversion for a circularly polarized Gaussian beam propagating along the optical axis of a uniaxial crystal. We extend the results to the case of white-light beams...

Focusing and correlation properties of white-light optical vortices.

Optics express

Shvedov V, Krolikowski W, Volyar A, Neshev D, Desyatnikov A, Kivshar Y.
PMID: 19498763
Opt Express. 2005 Sep 19;13(19):7393-8. doi: 10.1364/opex.13.007393.

We generate double-charge white-light optical vortices by sending a circularly polarized partially incoherent light through an uniaxial crystal. We show that the generated polichromatic vortices are structurally stable, and their correlation properties can be altered by the beam focusing,...

Stable vortex soliton in nonlocal media with orientational nonlinearity.

Optics letters

Izdebskaya YV, Shvedov VG, Jung PS, Krolikowski W.
PMID: 29328198
Opt Lett. 2018 Jan 01;43(1):66-69. doi: 10.1364/OL.43.000066.

We report on the first experimental observation of stable vortex solitons in nematic liquid crystals with nonlocal nonlinear reorientational response. We show how these nonlinear vortex beams can be formed and confined in extraordinary optical waves by employing the...

Anomalous interaction of spatial solitons in nematic liquid crystals.

Optics letters

Cyprych K, Jung PS, Izdebskaya Y, Shvedov V, Christodoulides DN, Krolikowski W.
PMID: 30644877
Opt Lett. 2019 Jan 15;44(2):267-270. doi: 10.1364/OL.44.000267.

We study experimentally the interaction of mutually incoherent bright spatial solitons in dye-doped nematic liquid crystals (LCs). The dye-induced light absorption results in a complex nonlinear optical response of the LC having spatially nonlocal focusing and defocusing contributions. The...

Transverse spin angular momentum of tightly focused full Poincaré beams.

Optics express

Zhu W, Shvedov V, She W, Krolikowski W.
PMID: 26832060
Opt Express. 2015 Dec 28;23(26):34029-41. doi: 10.1364/OE.23.034029.

We show theoretically that by tightly focusing a full Poincaré beam one can create states of light whose average spin angular momentum (SAM) is purely transverse. Moreover, the transverse SAM is significantly increased if a narrow annular aperture is...

Generation of single-charge optical vortices with an uniaxial crystal.

Optics express

Voylar A, Shvedov V, Fadeyeva T, Desyatnikov AS, Neshev DN, Krolikowski W, Kivshar YS.
PMID: 19516519
Opt Express. 2006 May 01;14(9):3724-9. doi: 10.1364/oe.14.003724.

We implement a novel experimental technique for generating mono- and polychromatic optical beams with on-axis single vortex by manipulating polarization singularities of light in birefringent crystals. We demonstrate that, in contrast to the well-known optical quadrupoles generated by beams...

Observation of polychromatic vortex solitons.

PMID: 18709110
Opt Lett. 2008 Aug 15;33(16):1851-3. doi: 10.1364/ol.33.001851.

We demonstrate experimentally the formation of polychromatic single- and double-charge optical vortex solitons by employing a lithium niobate crystal as a nonlinear medium with defocusing nonlinearity. We study the wavelength dependence of the vortex core localization and observe self-trapping...
