Light saturation curves show competence of the water splitting complex in inactive Photosystem II reaction centers.

Photosynthesis research

Nedbal L, Gibas C, Whitmarsh J.
PMID: 24415257
Photosynth Res. 1991 Dec;30(2):85-94. doi: 10.1007/BF00042006.

Photosystem II complexes of higher plants are structurally and functionally heterogeneous. While the only clearly defined structural difference is that Photosystem II reaction centers are served by two distinct antenna sizes, several types of functional heterogeneity have been demonstrated....

Twister mutant mice are defective for otogelin, a component specific to inner ear acellular membranes.

Mammalian genome : official journal of the International Mammalian Genome Society

Simmler MC, Zwaenepoel I, Verpy E, Guillaud L, Elbaz C, Petit C, Panthier JJ.
PMID: 11178734
Mamm Genome. 2000 Nov;11(11):961-966. doi: 10.1007/s003350010197.

Deafness is a common sensory defect in human. Our understanding of the molecular bases of this pathology comes from the study of a few genes that have been identified in human and/or in mice. Indeed, deaf mouse mutants are...

Probing highly confined optical fields in the focal region of a high NA parabolic mirror with subwavelength spatial resolution.

Journal of microscopy

Debus C, Lieb MA, Drechsler A, Meixner AJ.
PMID: 12787085
J Microsc. 2003 Jun;210:203-8. doi: 10.1046/j.1365-2818.2003.01091.x.

Parabolic mirrors with a high numerical aperture can be conveniently used to produce highly confined optical fields in the focal region. Furthermore, these fields can have interesting polarization behaviour due to the high numerical aperture. In particular, if the...

Self-affine surface morphology of plastically deformed metals.

Physical review letters

Zaiser M, Grasset FM, Koutsos V, Aifantis EC.
PMID: 15600851
Phys Rev Lett. 2004 Nov 05;93(19):195507. doi: 10.1103/PhysRevLett.93.195507. Epub 2004 Nov 05.

We analyze the surface morphology of metals after plastic deformation over a range of scales from 10 nm to 2 mm using atomic force microscopy and scanning white-light interferometry. We demonstrate that an initially smooth surface during deformation develops...

Direct measurement of frequency and polarization dependences of cross-phase modulation in fibers from high-resolution optical spectra.

Optics letters

Heras C, Subías J, Pelayo J, Villuendas F.
PMID: 16419862
Opt Lett. 2006 Jan 01;31(1):14-6. doi: 10.1364/ol.31.000014.

We present the results of an experiment for frequency and polarization dependence characterization of non-linear cross-phase-modulation (XPM) effects in optical fibers. The measurement technique is based on the direct analysis of high-resolution optical spectra of a signal wave that...

Universality of quantum gravity corrections.

Physical review letters

Das S, Vagenas EC.
PMID: 19113472
Phys Rev Lett. 2008 Nov 28;101(22):221301. doi: 10.1103/PhysRevLett.101.221301. Epub 2008 Nov 25.

We show that the existence of a minimum measurable length and the related generalized uncertainty principle (GUP), predicted by theories of quantum gravity, influence all quantum Hamiltonians. Thus, they predict quantum gravity corrections to various quantum phenomena. We compute...

Flow-field dynamics during droplet formation by dripping in hydrodynamic-focusing microfluidics.

Physical review. E, Statistical, nonlinear, and soft matter physics

Funfschilling D, Debas H, Li HZ, Mason TG.
PMID: 19658759
Phys Rev E Stat Nonlin Soft Matter Phys. 2009 Jul;80(1):015301. doi: 10.1103/PhysRevE.80.015301. Epub 2009 Jul 06.

Using microscopic particle image velocimetry, we examine the flow field around an oil droplet as it is formed by hydrodynamic focusing in an aqueous solution using a pressure-driven cross-channel microfluidic device. By detecting the temporal dependence of the instantaneous...

Mitigating heat dissipation in Raman lasers using coherent anti-stokes Raman scattering.

Physical review letters

Vermeulen N, Debaes C, Muys P, Thienpont H.
PMID: 17931007
Phys Rev Lett. 2007 Aug 31;99(9):093903. doi: 10.1103/PhysRevLett.99.093903. Epub 2007 Aug 28.

We present a novel technique that intrinsically mitigates the quantum-defect heating in Raman lasers. The basic principle of this so-called "coherent anti-Stokes Raman scattering (CARS)-based heat mitigation" is to suppress the phonon creation in the Raman medium by increasing...

Meat from rabbits reared either according to a standard (STAND) or a high quality norm (LABEL) or a low growth breeding (RUSSE) system were submitted to a sensory evaluation and to a large set of physicochemical measurements (weight of...
