PMID: 27284532
MethodsX. 2016 May 09;3:407-16. doi: 10.1016/j.mex.2016.05.002. eCollection 2016.

In experimental animal research body temperature (BT) is measured for the objective determination of an animals' physiological condition. Invasive, probe-based measurements are stressful and can influence experimental outcome. Alternatively BT can be determined touch-free from the emitted heat of...

TEMPO Monolayers on Si(100) Electrodes: Electrostatic Effects by the Electrolyte and Semiconductor Space-Charge on the Electroactivity of a Persistent Radical.

Journal of the American Chemical Society

Zhang L, Vogel YB, Noble BB, Gonçales VR, Darwish N, Brun AL, Gooding JJ, Wallace GG, Coote ML, Ciampi S.
PMID: 27373457
J Am Chem Soc. 2016 Aug 03;138(30):9611-9. doi: 10.1021/jacs.6b04788. Epub 2016 Jul 19.

This work demonstrates the effect of electrostatic interactions on the electroactivity of a persistent organic free radical. This was achieved by chemisorption of molecules of 4-azido-2,2,6,6-tetramethyl-1-piperdinyloxy (4-azido-TEMPO) onto monolayer-modified Si(100) electrodes using a two-step chemical procedure to preserve the...

Spatial-temporal-covariance-based modeling, analysis, and simulation of aero-optics wavefront aberrations.

J Opt Soc Am A Opt Image Sci Vis. 2014 Jul 01;31(7):1666-79. doi: 10.1364/JOSAA.31.001666.

We introduce a framework for modeling, analysis, and simulation of aero-optics wavefront aberrations that is based on spatial-temporal covariance matrices extracted from wavefront sensor measurements. Within this framework, we present a quasi-homogeneous structure function to analyze nonhomogeneous, mildly anisotropic...

Aerosol hygroscopic properties were linked to its chemical composition by using complementary online mass spectrometric techniques in a comprehensive chemical characterization study at a rural mountaintop station in central Germany in August 2012. In particular, atmospheric pressure chemical ionization...

Single-Dose CpG Immunization Protects Against a Heterosubtypic Challenge and Generates Antigen-Specific Memory T Cells.

Despite extensive research, influenza A virus (IAV) remains a major cause of morbidity, mortality, and healthcare expenditure. Emerging pandemics from highly pathogenic IAV strains, such as H5N1 and pandemic H1N1, highlight the need for universal, cross-protective vaccines. Current vaccine...

Regulation of Oleoresinosis in Grand Fir (Abies grandis) (Coordinate Induction of Monoterpene and Diterpene Cyclases and Two Cytochrome P450-Dependent Diterpenoid Hydroxylases by Stem Wounding).

Plant physiology

PMID: 12232380
Plant Physiol. 1994 Nov;106(3):999-1005. doi: 10.1104/pp.106.3.999.

Oleoresin (pitch) is a defensive secretion composed of monoterpene olefins (turpentine) and diterpene resin acids (rosin) that is produced in grand fir (Abies grandis Lindl.) stems in response to wounding. Monoterpene and diterpene biosynthesis are coordinately induced in wounded...

Multigrid preconditioned conjugate-gradient method for large-scale wave-front reconstruction.

J Opt Soc Am A Opt Image Sci Vis. 2002 Sep;19(9):1817-22. doi: 10.1364/josaa.19.001817.

We introduce a multigrid preconditioned conjugate-gradient (MGCG) iterative scheme for computing open-loop wave-front reconstructors for extreme adaptive optics systems. We present numerical simulations for a 17-m class telescope with n = 48756 sensor measurement grid points within the aperture,...

Management of Cervical Esophageal Carcinoma.

Surgery and radiotherapy yield equivalent results for patients with carcinoma of the cervical esophagus, with long-term survival of less than one in four patients. The advantages of radiotherapy are lower rates of acute morbidity and mortality compared with surgery,...

The bond strength of chlorine peroxide (ClOOCl) is studied by photoionization mass spectrometry. The experimental results are obtained from the fragmentation threshold yielding ClO+, which is observed at 11.52 +/- 0.025 eV. The O-O bond strength D(o) is derived...

Economic evaluation of MR cholangiopancreatography compared to diagnostic ERCP for the investigation of biliary tree obstruction.

International journal of surgery (London, England)

Vergel YB, Chilcott J, Kaltenthaler E, Walters S, Blakeborough A, Thomas S.

Int J Surg. 2006;4(1):12-9. doi: 10.1016/j.ijsu.2006.01.007. Epub 2006 Feb 21.

BACKGROUND: Use of magnetic resonance cholangiopancreatography (MRCP) for confirmation of presence of biliary obstruction is virtually risk-free. However, unlike diagnostic endoscopic retrograde cholangiopancreatography (ERCP), no therapeutic option can be offered simultaneously with MRCP. The aim of the study is...

We present two different implementations of the Fourier domain preconditioned conjugate gradient algorithm (FD-PCG) to efficiently solve the large structured linear systems that arise in optimal volume turbulence estimation, or tomography, for multi-conjugate adaptive optics (MCAO). We describe how...
