Separation of intra- and intermolecular contributions to the PELDOR signal.

Journal of magnetic resonance (San Diego, Calif. : 1997)

Schöps P, Plackmeyer J, Marko A.
PMID: 27243966
J Magn Reson. 2016 Aug;269:70-77. doi: 10.1016/j.jmr.2016.05.012. Epub 2016 May 24.

Pulsed Electron-electron Double Resonance (PELDOR) is commonly used to measure distances between native paramagnetic centers or spin labels attached to complex biological macromolecules. In PELDOR the energies of electron magnetic dipolar interactions are measured by analyzing the oscillation frequencies...

Korobko AV, Marques CM, Schöps M, Schädler V, Wiesner U, Mendes E.
PMID: 26267589
Soft Matter. 2015 Sep 28;11(36):7081-5. doi: 10.1039/c5sm01136a. Epub 2015 Aug 12.

The surface tension between the hydrophobic core and the solvent is known to play a major role in the self-assembly of diblock copolymer micelles in solution. Coulombic forces are also very important in the case of aggregates with weakly...

Perspectives of shaped pulses for EPR spectroscopy.

Journal of magnetic resonance (San Diego, Calif. : 1997)

Spindler PE, Schöps P, Kallies W, Glaser SJ, Prisner TF.
PMID: 28579101
J Magn Reson. 2017 Jul;280:30-45. doi: 10.1016/j.jmr.2017.02.023.

This article describes current uses of shaped pulses, generated by an arbitrary waveform generator, in the field of EPR spectroscopy. We show applications of sech/tanh and WURST pulses to dipolar spectroscopy, including new pulse schemes and procedures, and discuss...

Nutritional quality of seston for the freshwater herbivore Daphnia galeata × hyalina: biochemical versus mineral limitations.

Oecologia

Boersma M, Schöps C, McCauley E.
PMID: 28547189
Oecologia. 2001 Nov;129(3):342-348. doi: 10.1007/s004420100728. Epub 2001 Nov 01.

The quality of natural seston as food for zooplankters can be highly variable. Thus far, experimental evidence on the factors affecting food quality under natural conditions is scarce. Hence, in this study, we set out to investigate how Daphnia...

AP5Z1/SPG48 frequency in autosomal recessive and sporadic spastic paraplegia.

Molecular genetics & genomic medicine

Schlipf NA, Schüle R, Klimpe S, Karle KN, Synofzik M, Wolf J, Riess O, Schöls L, Bauer P.
PMID: 25333062
Mol Genet Genomic Med. 2014 Sep;2(5):379-82. doi: 10.1002/mgg3.87. Epub 2014 May 25.

Hereditary spastic paraplegias (HSP) constitute a rare and highly heterogeneous group of neurodegenerative disorders, defined clinically by progressive lower limb spasticity and pyramidal weakness. Autosomal recessive HSP as well as sporadic cases present a significant diagnostic challenge. Mutations in...

Strain-induced nonanalytic short-range order in the spin glass Cu(83)Mn(17).

Physical review letters

Reichert H, Bugaev VN, Shchyglo O, Schöps A, Sikula Y, Dosch H.
PMID: 11736464
Phys Rev Lett. 2001 Dec 03;87(23):236105. doi: 10.1103/PhysRevLett.87.236105. Epub 2001 Nov 15.

We present a theoretical and experimental study of the effect of lattice distortions on the short-range order and the energetics of ordering binary alloys. Applying a reciprocal space approach which accounts for the elastic response of the lattice, the...

[Classification of chronic pain. Quantification and grading with the Mainz Pain Staging System].

Schmerz (Berlin, Germany)

Pfingsten M, Schöps P, Wille T, Terp L, Hildebrandt J.
PMID: 12799906
Schmerz. 2000 Feb;14(1):10-7. doi: 10.1007/s004820000060.

INTRODUCTION: Chronic pain is an individually variable experience, incorporating physical, psychological and social dimensions. Chronic pain occurs in a broad spectrum of severity; therefore, a grading procedure is of crucial importance in clinical research and in epidemiologic studies. The...

Application of Phage Display in Selecting Tomato spotted wilt virus-Specific Single-Chain Antibodies (scFvs) for Sensitive Diagnosis in ELISA.

Phytopathology

Griep RA, Prins M, van Twisk C, Keller HJ, Kerschbaumer RJ, Kormelink R, Goldbach RW, Schots A.
PMID: 18944607
Phytopathology. 2000 Feb;90(2):183-90. doi: 10.1094/PHYTO.2000.90.2.183.

ABSTRACT A panel of recombinant single-chain antibodies (scFvs) against structural proteins of Tomato spotted wilt virus (TSWV) was retrieved from a human combinatorial scFv antibody library using the novel phage display technique. After subcloning the encoding DNA sequences in...

Electron-vibron coupling in high-resolution X-Ray absorption spectra of organic materials: NTCDA on Ag(111).

Physical review letters

Schöll A, Zou Y, Kilian L, Hübner D, Gador D, Jung C, Urquhart SG, Schmidt T, Fink R, Umbach E.
PMID: 15524822
Phys Rev Lett. 2004 Oct 01;93(14):146406. doi: 10.1103/PhysRevLett.93.146406. Epub 2004 Sep 30.

We report additional rich fine structures in high-resolution near-edge x-ray-absorption fine structure (NEXAFS) spectra of large organic molecules using NTCDA on Ag(111) as an example. These fine structures are completely interpreted as vibronic coupling to electronic core excitations. The...

Single-mode operation of a standing wave miniature Nd laser pumped by laser diodes.

PMID: 16471785
J Phys Chem B. 2006 Feb 09;110(5):2074-9. doi: 10.1021/jp0557013.

The recombination dynamics of zinc-blende-type, deep-red emitting CdTe/CdS core-shell nanocrystals is studied over a wide temperature range. Two characteristic decay regimes are found: a temperature-dependent decay component of a few nanoseconds and a long-living temperature-independent component of approximately 315...
