Craniopharyngioma causing bilateral vision loss 4 months after unremarkable magnetic resonance imaging of the brain.

Journal of neurosciences in rural practice

Betts R, Margo CE, Drucker M.
PMID: 26167023
J Neurosci Rural Pract. 2015 Jul-Sep;6(3):392-4. doi: 10.4103/0976-3147.158770.

A 65-year-old man developed bilateral vision loss 4 months after magnetic resonance imaging demonstrated no lesion in the vicinity of the optic chiasm, hypothalamus, and suprasellar tissues. Repeat computed tomography 3 months later showed a predominantly cystic mass of...

Single-mode air-clad liquid-core waveguides on a surface energy patterned substrate.

Optics letters

Vandewiele S, Brans T, Van Landschoot L, Komorowska K, Verstuyft S, Subramanian A, Hu C, Beunis F, Baets R.
PMID: 25121914
Opt Lett. 2014 Aug 15;39(16):4942-5. doi: 10.1364/OL.39.004942.

We demonstrate a new kind of single-mode micro-optical waveguide based on a liquid core on top of solid substrate and air cladding. The liquid is held in place by surface tension and patterned surface energy on the substrate. Due...

Cerebral Microcirculation during Experimental Normovolaemic Anemia.

Frontiers in neurology

Bellapart J, Cuthbertson K, Dunster K, Diab S, Platts DG, Raffel OC, Gabrielian L, Barnett A, Paratz J, Boots R, Fraser JF.
PMID: 26869986
Front Neurol. 2016 Feb 02;7:6. doi: 10.3389/fneur.2016.00006. eCollection 2016.

Anemia is accepted among critically ill patients as an alternative to elective blood transfusion. This practice has been extrapolated to head injury patients with only one study comparing the effects of mild anemia on neurological outcome. There are no...

Bright and dark plasmon resonances of nanoplasmonic antennas evanescently coupled with a silicon nitride waveguide.

Optics express

Peyskens F, Subramanian AZ, Neutens P, Dhakal A, Van Dorpe P, Le Thomas N, Baets R.
PMID: 25836168
Opt Express. 2015 Feb 09;23(3):3088-101. doi: 10.1364/OE.23.003088.

In this work we investigate numerically and experimentally the resonance wavelength tuning of different nanoplasmonic antennas excited through the evanescent field of a single mode silicon nitride waveguide and study their interaction with this excitation field. Experimental interaction efficiencies...

Loneliness and Schizotypy Are Distinct Constructs, Separate from General Psychopathology.

Frontiers in psychology

Badcock JC, Barkus E, Cohen AS, Bucks R, Badcock DR.
PMID: 27458412
Front Psychol. 2016 Jul 07;7:1018. doi: 10.3389/fpsyg.2016.01018. eCollection 2016.

Loneliness is common in youth and associated with a significantly increased risk of psychological disorders. Although loneliness is strongly associated with psychosis, its relationship with psychosis proneness is unclear. Our aim in this paper was to test the hypothesis...

Silicon-organic hybrid (SOH) IQ modulator using the linear electro-optic effect for transmitting 16QAM at 112 Gbit/s.

Optics express

Korn D, Palmer R, Yu H, Schindler PC, Alloatti L, Baier M, Schmogrow R, Bogaerts W, Selvaraja SK, Lepage G, Pantouvaki M, Wouters JM, Verheyen P, Van Campenhout J, Chen B, Baets R, Absil P, Dinu R, Koos C, Freude W, Leuthold J.
PMID: 23736576
Opt Express. 2013 Jun 03;21(11):13219-27. doi: 10.1364/OE.21.013219.

Advanced modulation formats call for suitable IQ modulators. Using the silicon-on-insulator (SOI) platform we exploit the linear electro-optic effect by functionalizing a photonic integrated circuit with an organic χ(2)-nonlinear cladding. We demonstrate that this silicon-organic hybrid (SOH) technology allows...

Heterogeneously integrated III-V-on-silicon multibandgap superluminescent light-emitting diode with 290 nm optical bandwidth.

Optics letters

De Groote A, Peters JD, Davenport ML, Heck MJ, Baets R, Roelkens G, Bowers JE.
PMID: 25121874
Opt Lett. 2014 Aug 15;39(16):4784-7. doi: 10.1364/OL.39.004784.

A broadband superluminescent III-V-on-silicon light-emitting diode (LED) was realized. To achieve the large bandwidth, quantum well intermixing and multiple die bonding of InP on a silicon photonic waveguide circuit were combined for the first time, to the best of...

Scattering at sidewall roughness in photonic crystal slabs.

Optics letters

Bogaerts W, Bienstman P, Baets R.
PMID: 12747708
Opt Lett. 2003 May 01;28(9):689-91. doi: 10.1364/ol.28.000689.

We have simulated the effect of sidewall roughness in photonic-crystallike structures with different vertical refractive-index contrast. We treated the scattering off a sidewall irregularity as a radiating dipole excited by the incident waveguide mode. We show that the loss...

Compact spot-size converters with fiber-matched antiresonant reflecting optical waveguides.

Applied optics

Galarza M, De Mesel K, Baets R, Martínez A, Aramburu C, López-Amo M.
PMID: 12952328
Appl Opt. 2003 Aug 20;42(24):4841-6. doi: 10.1364/ao.42.004841.

We propose a concept for InGaAsP-InP 1.55-microm lasers integrated with spot-size converters based on modal interference between the modes of the structure formed by an active waveguide and an underlying fiber-matched antiresonant reflecting optical waveguide. Simulation results show that...

Evaluation of effluent toxicity and ambient toxicity in a polluted lowland river.

Environmental pollution (Barking, Essex : 1987)

Bervoets L, Baillieul M, Blust R, Verheyen R.

Environ Pollut. 1996;91(3):333-41. doi: 10.1016/0269-7491(96)80915-8.

The impact of an industrial effluent containing high loads of calcium, cadmium, lead chloride and sulphate, on a river ecosystem was assessed using a combination of an effluent toxicity test, an ambient toxicity test and an ecological survey. Only...
