Calculation of the vectorial field distribution in a stratified focal region of a high numerical aperture imaging system.

Optics express

van de Nes A, Billy L, Pereira S, Braat J.
PMID: 19474948
Opt Express. 2004 Apr 05;12(7):1281-93. doi: 10.1364/opex.12.001281.

We present an algorithm for calculating the field distribution in the focal region of stratified media which is fast and easy to implement. Using this algorithm we study the effect on the electric field distribution of an air gap...

Never Too Old? Occurrence of Medulloblastoma in the Elderly beyond the 70th Year of Life.

Case reports in neurological medicine

Maslehaty H, Van de Nes J, Teuber-Hanselmann S, Moenninghoff C, Sure U, Oezkan N.
PMID: 29984017
Case Rep Neurol Med. 2018 Jun 07;2018:8639404. doi: 10.1155/2018/8639404. eCollection 2018.

The occurrence of medulloblastoma (MB) in the elderly is an absolutely rare event. Concerning this issue we report on two MB patients beyond the 70th year of life. Two patients older than 70 years presented with a mass in...

Rigorous analysis of spheres in Gauss-Laguerre beams.

Optics express

van de Nes AS, Török P.
PMID: 19550606
Opt Express. 2007 Oct 01;15(20):13360-74. doi: 10.1364/oe.15.013360.

In this paper we develop a rigorous formulation of Gauss- Laguerre beams in terms of Mie scattering coefficients which permits us to quasi-analytically treat the interaction of a spherical particle located in the focal region of a possibly high...

Comparison between optical coherence tomography imaging and histological sections of peripheral nerves.

Journal of neurosurgery

Carolus AE, Möller J, Hofmann MR, van de Nes JAP, Welp H, Schmieder K, Brenke C.
PMID: 31756711
J Neurosurg. 2019 Nov 22;1-8. doi: 10.3171/2019.8.JNS191278. Epub 2019 Nov 22.

OBJECTIVE: Optical coherence tomography (OCT) is an imaging technique that uses the light-backscattering properties of different tissue types to generate an image. In an earlier feasibility study the authors showed that it can be applied to visualize human peripheral...

Towards defining reference materials for measuring extracellular vesicle refractive index, epitope abundance, size and concentration.

Journal of extracellular vesicles

Welsh JA, van der Pol E, Bettin BA, Carter DRF, Hendrix A, Lenassi M, Langlois MA, Llorente A, van de Nes AS, Nieuwland R, Tang V, Wang L, Witwer KW, Jones JC.
PMID: 33062218
J Extracell Vesicles. 2020 Sep 24;9(1):1816641. doi: 10.1080/20013078.2020.1816641.

Accurate characterization of extracellular vesicles (EVs) is critical to explore their diagnostic and therapeutic applications. As the EV research field has developed, so too have the techniques used to characterize them. The development of reference materials are required for...

Cylindrical vector beam focusing through a dielectric interface: comment.

Optics express

van de Nes A, Munro P, Pereira S, Braat J, Török P.
PMID: 19474909
Opt Express. 2004 Mar 08;12(5):967-9. doi: 10.1364/opex.12.000967.

Errors in the results and conclusions presented in the paper "Cylindrical vector beam focusing through a dielectric interface" by Biss and Brown (Opt. Express 9, 490-497 (2001)) are discussed.

Motte J, Kreitschmann-Andermahr I, Fisse AL, Börnke C, Schroeder C, Pitarokoili K, Müller O, Lukas C, van de Nes J, Buslei R, Gold R, Ayzenberg I.
PMID: 28243612
Neurol Neuroimmunol Neuroinflamm. 2017 Feb 14;4(3):e332. doi: 10.1212/NXI.0000000000000332. eCollection 2017 May.

OBJECTIVE: To report a rare case of incipient granulomatous hypophysitis presenting by atypical trigemino-autonomic cephalalgia (TAC) and Horner syndrome.METHODS: The patient was investigated with repeated brain MRI, CSF examination, thoracic CT, Doppler and duplex ultrasound of the cerebral arteries,...

Extended Nijboer-Zernike representation of the vector field in the focal region of an aberrated high-aperture optical system.

Journal of the Optical Society of America. A, Optics, image science, and vision

Braat JJ, Dirksen P, Janssen AJ, van de Nes AS.
PMID: 14686507
J Opt Soc Am A Opt Image Sci Vis. 2003 Dec;20(12):2281-92. doi: 10.1364/josaa.20.002281.

Taking the classical Ignatowsky/Richards and Wolf formulas as our starting point, we present expressions for the electric field components in the focal region in the case of a high-numerical-aperture optical system. The transmission function, the aberrations, and the spatially...
