A novel processing approach for free-standing porous non-oxide ceramic supports from polycarbosilane and polysilazane precursors.

Journal of the European Ceramic Society

Konegger T, Patidar R, Bordia RK.
PMID: 26339126
J Eur Ceram Soc. 2015 Sep;35(9):2679-2683. doi: 10.1016/j.jeurceramsoc.2015.03.009.

In this contribution, a low-pressure/low-temperature casting technique for the preparation of novel free-standing macrocellular polymer-derived ceramic support structures is presented. Preceramic polymers (polycarbosilane and poly(vinyl)silazane) are combined with sacrificial porogens (ultra-high molecular weight polyethylene microbeads) to yield porous ceramic...

Quantification of 99mTc-DPD concentration in the lumbar spine with SPECT/CT.

EJNMMI research

Cachovan M, Vija AH, Hornegger J, Kuwert T.
PMID: 23738809
EJNMMI Res. 2013 Jun 05;3(1):45. doi: 10.1186/2191-219X-3-45.

BACKGROUND: Routine single-photon emission computed tomography (SPECT) currently lacks quantitative information on regional activity concentration (ACC) of the injected tracer (e.g. kBq/ml). Furthermore, little is known on the skeletal absolute concentration of 99mTc-DPD after intravenous injection in bone scintigraphy....

Planar, Polysilazane-Derived Porous Ceramic Supports for Membrane and Catalysis Applications.

Journal of the American Ceramic Society. American Ceramic Society

Konegger T, Williams LF, Bordia RK.
PMID: 26681809
J Am Ceram Soc. 2015 Oct 01;98(10):3047-3053. doi: 10.1111/jace.13758.

Porous, silicon carbonitride-based ceramic support structures for potential membrane and catalysis applications were generated from a preceramic polysilazane precursor in combination with spherical, ultrahigh-molecular weight polyethylene microparticles through a sacrificial filler approach. A screening evaluation was used for the...

PMID: 11227060
ALTEX. 1989;6(1):29-36.

Aggregate cultures are primary cell cultures prepared from dissociated fetal cells. In rotation-mediated culture under rigorously controlled conditions, the isolated cells are able to reaggregate spontaneously, and to form a large number of practically identical spheres. The three-dimensional cell...

Retinal Nerve Fiber Layer Segmentation on FD-OCT Scans of Normal Subjects and Glaucoma Patients.

Mayer MA, Hornegger J, Mardin CY, Tornow RP.
PMID: 21258556
Biomed Opt Express. 2010 Nov 08;1(5):1358-1383. doi: 10.1364/BOE.1.001358.

Automated measurements of the retinal nerve fiber layer thickness on circular OCT B-Scans provide physicians additional parameters for glaucoma diagnosis. We propose a novel retinal nerve fiber layer segmentation algorithm for frequency domain data that can be applied on...

Wavelet denoising of multiframe optical coherence tomography data.

Biomedical optics express

Mayer MA, Borsdorf A, Wagner M, Hornegger J, Mardin CY, Tornow RP.
PMID: 22435103
Biomed Opt Express. 2012 Mar 01;3(3):572-89. doi: 10.1364/BOE.3.000572. Epub 2012 Feb 22.

We introduce a novel speckle noise reduction algorithm for OCT images. Contrary to present approaches, the algorithm does not rely on simple averaging of multiple image frames or denoising on the final averaged image. Instead it uses wavelet decompositions...

Polarization sensitive optical coherence tomography of melanin provides intrinsic contrast based on depolarization.

Baumann B, Baumann SO, Konegger T, Pircher M, Götzinger E, Schlanitz F, Schütze C, Sattmann H, Litschauer M, Schmidt-Erfurth U, Hitzenberger CK.
PMID: 22808437
Biomed Opt Express. 2012 Jul 01;3(7):1670-83. doi: 10.1364/BOE.3.001670. Epub 2012 Jun 21.

Polarization sensitive optical coherence tomography (PS-OCT) is a functional extension of OCT. In addition to imaging based on tissue reflectivity, PS-OCT also enables depth-resolved mapping of sample polarization properties such as phase-retardation, birefringent axis orientation, Stokes vectors, and degree...

Thermal Critical Points and Quantum Critical End Point in the Frustrated Bilayer Heisenberg Antiferromagnet.

Physical review letters

Stapmanns J, Corboz P, Mila F, Honecker A, Normand B, Wessel S.
PMID: 30296119
Phys Rev Lett. 2018 Sep 21;121(12):127201. doi: 10.1103/PhysRevLett.121.127201.

We consider the finite-temperature phase diagram of the S=1/2 frustrated Heisenberg bilayer. Although this two-dimensional system may show magnetic order only at zero temperature, we demonstrate the presence of a line of finite-temperature critical points related to the line...

Prevalence and determinants of exercise-induced left ventricular dysfunction in patients with coronary artery disease.

European journal of clinical investigation

Honegger U, Walter JE, Mueller D, Puelacher C, Schaerli N, Twerenbold R, Badertscher P, Boeddinghaus J, Nestelberger T, du Fay de Lavallaz J, Wussler D, Pfister O, Jeger R, Kaiser C, Wild D, Schmidt-Trucksäss A, Reichlin T, Mueller C.

Eur J Clin Invest. 2019 Mar 29;e13112. doi: 10.1111/eci.13112. Epub 2019 Mar 29.

BACKGROUND: The phenomenon of exercise-induced left ventricular dysfunction (LVD) is incompletely understood. Better understanding of its prevalence and determinants might help to address the current potential oversimplification of the relation between physical activity and cardiac health in patients with...
