Incidence of small bowel neoplasia in Lynch syndrome assessed by video capsule endoscopy

Endoscopy International Open, 2017
Background and study aims Lynch syndrome (LS) patients have an increased risk of small bowel cancer. The question is whether surveillance will lead to early detection of (pre)malignant lesions. We recently reported on prevalence of small bowel neoplasia (

Random-field Ising-type transition of pure and doped SBN from the relaxor into the ferroelectric state

, 2003
Activated critical dynamics and vanishing of the susceptibility ratio $a_3 =\chi_3/\chi_1^4\rightarrow 0$ in the zero-frequency limit unequivocally evidence the phase transitions of the uniaxial relaxor crystals SBN, SBN:$\chem{Ce}$ and SBN:$\chem{Cr ...

Ferroelectric and dielectric characterization studies on relaxor- and ferroelectric-like strontium-barium niobates

Condensed Matter Physics, 2013
Ferroelectric domain structure evolution induced by an external electric field was investigated by means of nematic liquid crystal (NLC) method in two strontium-barium niobate single crystals of nominal composition: Sr0.70Ba0.30Nb2O6 (SBN:70 - relaxor ...

The influence of rest period instructions on the default mode network

Frontiers in Human Neuroscience, 2010
The default mode network (DMN) refers to regional brain activity that is greater during rest periods than during attention-demanding tasks and many studies have reported DMN alterations in patient populations.

Investigation of far infrared transitions of Ce3+ in congruent SBN crystals

, 2004
Three relatively sharp FIR absorption bands of Ce3+ in Strontium Barium Niobate (SBN) are observed in the 2000-3000 cm(-1) region. A subband structure of these bands indicates three slightly inequivalent positions of the Ce3+ in the SBN crystal lattice ...

Two-wave mixing in photorefractive SBN planar waveguides

, 1995
Planar waveguides have been fabricated in SBN:61 and SBN:75 by ion-beam implantation. The implantation was carried out using 2.0MeV H+ ions with doses ranging from 2x10 for the TE mode.
