Phys Rev Lett. 2015 Mar 20;114(11):112501. doi: 10.1103/PhysRevLett.114.112501. Epub 2015 Mar 19.

The spin polarizabilities of the nucleon describe how the spin of the nucleon responds to an incident polarized photon. The most model-independent way to extract the nucleon spin polarizabilities is through polarized Compton scattering. Double-polarized Compton scattering asymmetries on...

Long-Range Electrostatic Effects in QM/MM Studies of Enzymatic Reactions: Application of the Solvated Macromolecule Boundary Potential.

Journal of chemical theory and computation

Benighaus T, Thiel W.
PMID: 26606237
J Chem Theory Comput. 2011 Jan 11;7(1):238-49. doi: 10.1021/ct1005455. Epub 2010 Dec 03.

Long-range electrostatic interactions are important in simulations of enzymatic reactions. They can be divided into the effects due to bulk solvent and those due to the electrostatic potential of the outer macromolecule. We study and quantify the importance of...

Dip-in depletion optical lithography of three-dimensional chiral polarizers.

Optics letters

Thiel M, Ott J, Radke A, Kaschke J, Wegener M.
PMID: 24321972
Opt Lett. 2013 Oct 15;38(20):4252-5. doi: 10.1364/OL.38.004252.

We combine the concepts of dip-in and stimulated-emission-depletion-inspired optical lithography for the first time to fabricate three-dimensional (3D) nanostructures for photonics. For depletion of the photoinitiator ITX we employ a fiber-coupled laser diode at 639 nm wavelength. To demonstrate...

Spatiotemporal Dynamics of Oligofructan Metabolism and Suggested Functions in Developing Cereal Grains.

Frontiers in plant science

Peukert M, Thiel J, Mock HP, Marko D, Weschke W, Matros A.
PMID: 26834760
Front Plant Sci. 2016 Jan 19;6:1245. doi: 10.3389/fpls.2015.01245. eCollection 2015.

Oligofructans represent one of the most important groups of sucrose-derived water-soluble carbohydrates in the plant kingdom. In cereals, oligofructans accumulate in above ground parts of the plants (stems, leaves, seeds) and their biosynthesis leads to the formation of both...

Disentangling regular and chaotic motion in the standard map using complex network analysis of recurrences in phase space.

Chaos (Woodbury, N.Y.)

Zou Y, Donner RV, Thiel M, Kurths J.
PMID: 26931601
Chaos. 2016 Feb;26(2):023120. doi: 10.1063/1.4942584.

Recurrence in the phase space of complex systems is a well-studied phenomenon, which has provided deep insights into the nonlinear dynamics of such systems. For dissipative systems, characteristics based on recurrence plots have recently attracted much interest for discriminating...

The Dark Side of the Mushroom Spring Microbial Mat: Life in the Shadow of Chlorophototrophs. I. Microbial Diversity Based on 16S rRNA Gene Amplicons and Metagenomic Sequencing.

Frontiers in microbiology

Front Microbiol. 2016 Jun 17;7:919. doi: 10.3389/fmicb.2016.00919. eCollection 2016.

Microbial-mat communities in the effluent channels of Octopus and Mushroom Springs within the Lower Geyser Basin at Yellowstone National Park have been studied for nearly 50 years. The emphasis has mostly focused on the chlorophototrophic bacterial organisms of the...

Time averages in continuous-time random walks.

Physical review. E

Thiel F, Sokolov IM.
PMID: 28297905
Phys Rev E. 2017 Feb;95(2):022108. doi: 10.1103/PhysRevE.95.022108. Epub 2017 Feb 07.

We investigate the time-averaged square displacement (TASD) of continuous-time random walks with respect to the number of steps N which the random walker performed during the data acquisition time T. We prove that in each realization the TASD grows...

Renal disease is a well-recognized complication among patients with HIV infection. Viral infection itself and the use of some antiretroviral drugs contribute to this condition. The thick ascending limb of Henle's loop (TALH) is the tubule segment where free...

3D direct laser writing using a 405  nm diode laser.

Optics letters

Mueller P, Thiel M, Wegener M.
PMID: 25503012
Opt Lett. 2014 Dec 15;39(24):6847-50. doi: 10.1364/OL.39.006847.

Three-dimensional (3D) direct laser writing commonly uses near-infrared femtosecond laser pulses. Here, we use a quasi-cw blue diode laser at a 405 nm wavelength. As prerequisite, we identify photoresist systems that unambiguously show nonlinear multiphoton polymerization at this excitation...
