Double polarization active Y junctions in the L band, based on Ti:LiNbO3 lithium niobate waveguides: polarization and contrast performances.

Optics letters

Heidmann S, Courjal N, Martin G.
PMID: 23381243
Opt Lett. 2012 Aug 15;37(16):3318-20. doi: 10.1364/OL.37.003318.

Double polarization electro-optic beam combiners based on a Ti:diffusion lithium niobate waveguide have been developed for mid-infrared applications. A monochromatic rejection ratio of up to 33 dB at λ=3.39 μm was obtained, as well as wideband fringes showing low...

Non-Pharmacological Methods and Post-Operative Pain Relief: An Observational Study.

Anesthesiology and pain medicine

Komann M, Weinmann C, Schwenkglenks M, Meissner W.
PMID: 31341822
Anesth Pain Med. 2019 Apr 20;9(2):e84674. doi: 10.5812/aapm.84674. eCollection 2019 Apr.

BACKGROUND: Non-pharmacological methods (NPMs) like cold packs, acupuncture, meditation or distractions are supposed to ease acute post-surgical pain.OBJECTIVES: This study assessed how frequently these methods are used in clinical routine and if their use is associated with pain relief...

Toward quasi-DC conductivity of warm dense matter measured by single-shot terahertz spectroscopy.

The Review of scientific instruments

Ofori-Okai BK, Descamps A, Lu J, Seipp LE, Weinmann A, Glenzer SH, Chen Z.
PMID: 30399773
Rev Sci Instrum. 2018 Oct;89(10):10D109. doi: 10.1063/1.5038944.

We present an experimental setup capable of measuring the near DC conductivity of laser generated warm dense matter using single-shot terahertz time-domain spectroscopy. The setup uses a reflective echelon and balanced detection to record THz waveforms with a minimum...

Distribution and population density of the bushcricket Decticus verrucivorus in a damp-meadow biotope.

Oecologia

Weidemann S, Stiedl O, Kalmring K.
PMID: 28312713
Oecologia. 1990 Mar;82(3):369-373. doi: 10.1007/BF00317485.

A population of Decticus verrucivorus (Orthoptera: Tettigoniidae) was studied in the field over two successive years. The majority of insects accumulate only in certain parts of a diverse habitat. In this area the mean population density of adult Decticus...

Characterization and control of the electro-optic phase dispersion in lithium niobate modulators for wide spectral band interferometry applications in the mid-infrared.

Applied optics

Heidmann S, Ulliac G, Courjal N, Martin G.
PMID: 29047548
Appl Opt. 2017 May 10;56(14):4153-4157. doi: 10.1364/AO.56.004153.

Mid-infrared wideband modulation (3.2-3.7 μm) is achieved in an electro-optic Y-junction using lithium niobate waveguides in TE polarized light. Comparison between external (scanning mirror) and internal (electro-optical) modulation allows studying the chromatic polynomial dependence of the relative phase. Internal...

Mechanisms of doxorubicin resistance in hepatocellular carcinoma.

Hepatic oncology

Cox J, Weinman S.
PMID: 26998221
Hepat Oncol. 2016 Jan 01;3(1):57-59. doi: 10.2217/hep.15.41.

Hepatocellular carcinoma, one of the most common solid tumors worldwide, is poorly responsive to available chemotherapeutic approaches. While systemic chemotherapy is of limited benefit, intra-arterial delivery of doxorubicin to the tumor frequently produces tumor shrinkage. Its utility is limited,...

Risk Stratification in Advanced Biliary Tract Cancer: Validation of the A.L.A.N. Score.

INTRODUCTION: IgA nephropathy is a chronic renal disease characterized by mesangial immunodeposits that contain autoantigen, which is aberrantly glycosylated IgA1 with some hinge-region METHODS: We characterized IL-6 signaling pathways involved in the overproduction of galactose-deficient IgA1. To understand molecular...
