Successful laparoscopic repair of a large traumatic sigmoid perforation.

Journal of surgical case reports

de Bakker J, Bruin S.
PMID: 24960779
J Surg Case Rep. 2012 Feb 01;2012(2):3. doi: 10.1093/jscr/2012.2.3.

Bowel perforation can be potentially fatal. We describe the case of a 42-year-old male who presented with severe abdominal pain following anal fisting. Clinical examination revealed tenderness of the complete abdomen with signs of peritonism. A CT-scan with rectal...

Generation of neutral atomic beams utilizing photodetachment by high power diode laser stacks.

The Review of scientific instruments

O'Connor AP, Grussie F, Bruhns H, de Ruette N, Koenning TP, Miller KA, Savin DW, Stützel J, Urbain X, Kreckel H.
PMID: 26628128
Rev Sci Instrum. 2015 Nov;86(11):113306. doi: 10.1063/1.4934873.

We demonstrate the use of high power diode laser stacks to photodetach fast hydrogen and carbon anions and produce ground term neutral atomic beams. We achieve photodetachment efficiencies of ∼7.4% for H(-) at a beam energy of 10 keV...

Atmospheric pressure photoionization: an ionization method for liquid chromatography-mass spectrometry.

Analytical chemistry

Robb DB, Covey TR, Bruins AP.
PMID: 10952556
Anal Chem. 2000 Aug 01;72(15):3653-9. doi: 10.1021/ac0001636.

Atmospheric pressure photoionization (APPI) has been successfully demonstrated to provide high sensitivity to LC-MS analysis. A vacuum-ultraviolet lamp designed for photoionization detection in gas chromatography is used as a source of 10-eV photons. The mixture of samples and solvent...

Experimental error filtration for quantum communication over highly noisy channels.

Physical review letters

Lamoureux LP, Brainis E, Cerf NJ, Emplit P, Haelterman M, Massar S.
PMID: 16090449
Phys Rev Lett. 2005 Jun 17;94(23):230501. doi: 10.1103/PhysRevLett.94.230501. Epub 2005 Jun 13.

Error filtration is a method for encoding the quantum state of a single particle into a higher dimensional Hilbert space in such a way that it becomes less sensitive to noise. We have realized a fiber optics demonstration of...

Enhanced cross phase modulation instability in birefringent photonic crystal fibers in the anomalous dispersion regime.

Optics express

Nguyen AT, Phan Huy K, Brainis E, Mergo P, Wojcik J, Nasilowski T, Van Erps J, Thienpont H, Massar S.
PMID: 19529204
Opt Express. 2006 Sep 04;14(18):8290-7. doi: 10.1364/oe.14.008290.

We study Cross Phase Modulational Instability (CPMI) -a particular form of vector modulational instability- in the anomalous dispersion regime in highly birefringent, strongly dispersive optical fibers. When the pump power is high, the detuning of the Scalar Modulational Instability...

Spontaneous growth of Raman Stokes and anti-Stokes waves in fibers.

Optics letters

Brainis E, Clemmen S, Massar S.
PMID: 17909584
Opt Lett. 2007 Oct 01;32(19):2819-21. doi: 10.1364/ol.32.002819.

Using the quantum theory of light, we derive general analytical expressions of Stokes and anti-Stokes spectral photon-flux densities that are spontaneously generated by a single monochromatic pump wave propagating in a single-mode optical fiber. We validate our results by...

High-precision laser-assisted absolute determination of x-ray diffraction angles.

The Review of scientific instruments

Kubicek K, Braun J, Bruhns H, López-Urrutia JR, Mokler PH, Ullrich J.
PMID: 22299924
Rev Sci Instrum. 2012 Jan;83(1):013102. doi: 10.1063/1.3662412.

A novel technique for absolute wavelength determination in high-precision crystal x-ray spectroscopy recently introduced has been upgraded reaching unprecedented accuracies. The method combines visible laser beams with the Bond method, where Bragg angles (θ and -θ) are determined without...

High prevalence of fecal carriage of extended spectrum β-lactamase/AmpC-producing Enterobacteriaceae in cats and dogs.

Frontiers in microbiology

Hordijk J, Schoormans A, Kwakernaak M, Duim B, Broens E, Dierikx C, Mevius D, Wagenaar JA.
PMID: 23966992
Front Microbiol. 2013 Aug 16;4:242. doi: 10.3389/fmicb.2013.00242. eCollection 2013.

Extended-spectrum-β-lactamase (ESBL)/AmpC producing Enterobacteriaceae have been reported worldwide amongst isolates obtained from humans, food-producing animals, companion animals, and environmental sources. However, data on prevalence of fecal carriage of ESBL/AmpC producing Enterobacteriaceae in healthy companion animals is limited. This pilot...

Carbon monoxide in clouds at low metallicity in the dwarf irregular galaxy WLM.

Nature

Elmegreen BG, Rubio M, Hunter DA, Verdugo C, Brinks E, Schruba A.
PMID: 23538829
Nature. 2013 Mar 28;495(7442):487-9. doi: 10.1038/nature11933.

Carbon monoxide (CO) is the primary tracer for interstellar clouds where stars form, but it has never been detected in galaxies in which the oxygen abundance relative to hydrogen is less than 20 per cent of that of the...
