Reconstruction algorithm for single-particle diffraction imaging experiments.

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

Loh NT, Elser V.
PMID: 19792279
Phys Rev E Stat Nonlin Soft Matter Phys. 2009 Aug;80(2):026705. doi: 10.1103/PhysRevE.80.026705. Epub 2009 Aug 24.

We introduce the EMC algorithm for reconstructing a particle's three-dimensional (3D) diffraction intensity from very many photon shot-noise limited two-dimensional measurements, when the particle orientation in each measurement is unknown. The algorithm combines a maximization step (M) of the...

Witnessing effective entanglement over a 2 km fiber channel.

Optics express

Wittmann C, Fürst J, Wiechers C, Elser D, Häseler H, Lütkenhaus N, Leuchs G.
PMID: 20389462
Opt Express. 2010 Mar 01;18(5):4499-509. doi: 10.1364/OE.18.004499.

We present a fiber-based continuous-variable quantum key distribution system. In the scheme, a quantum signal of two non-orthogonal weak optical coherent states is sent through a fiber-based quantum channel. The receiver simultaneously measures conjugate quadratures of the light using...

Solid-solid interface formation in TiO2 nanoparticle networks.

Langmuir : the ACS journal of surfaces and colloids

Baumann SO, Elser MJ, Auer M, Bernardi J, Hüsing N, Diwald O.
PMID: 21265546
Langmuir. 2011 Mar 01;27(5):1946-53. doi: 10.1021/la104213d. Epub 2011 Jan 25.

Aiming at a comparison of microstructure and paramagnetic properties of mesoporous TiO(2) nanoparticle networks, we subjected entirely different TiO(2-x) precursor structures to vacuum annealing. The transformation of an amorphous TiO(2-x) gel--obtained by sol-gel processing of an ethylene glycol-modified titanium...

Electronic structures of octahedral Ni(II) complexes with "click" derived triazole ligands: a combined structural, magnetometric, spectroscopic, and theoretical study.

The coordination complexes of Ni(II) with the tripodal ligands tpta (tris[(1-phenyl-1H-1,2,3-triazol-4-yl)methyl]amine), tbta ([(1-benzyl-1H-1,2,3-triazol-4-yl)methyl]amine), and tdta (tris[(1-(2,6-diisopropyl-phenyl)-1H-1,2,3-triazol-4-yl)methyl]amine) and the bidentate ligand pyta (1-(2,6-diisopropylphenyl)-4-(2-pyridyl)-1,2,3-triazole), [Ni(tpta)2](BF4)2 (1), [Ni(tbta)2](BF4)2 (2), [Ni(tdta)2](BF4)2 (3), and [Ni(pyta)3](BF4)2 (4), were synthesized from Ni(BF4)2·6H2O and the corresponding ligands....

Selective inguinal lymphadenectomy in the treatment of invasive squamous cell carcinoma of the vulva.

International journal of surgical oncology

Desimone CP, Elder J, van Nagell JR.
PMID: 22312500
Int J Surg Oncol. 2011;2011:284374. doi: 10.1155/2011/284374. Epub 2011 Jun 09.

En bloc radical vulvectomy with bilateral inguinofemoral lymphadenectomy has now been replaced by radical wide excision and selective inguinal lymphadenectomy based on the stage and location of invasive vulvar cancer. Early stage lateral cancers can be effectively treated by...

Recent experiments at free-electron laser X-ray sources have been able to resolve the intensity distributions about Bragg peaks in nanocrystals of large biomolecules. Information derived from small shifts in the peak positions augment the Bragg samples of the particle...
