Photosynthesis in copepods.

Science (New York, N.Y.)

Epp RW, Lewis WM.
PMID: 17812261
Science. 1981 Dec 18;214(4527):1349-50. doi: 10.1126/science.214.4527.1349.

Zooplankton grazers consume appreciable amounts of algae that are not digested. Indigestibility has been considered of adaptive value to the algae and an unqualified disadvantage to the grazer. In Cartesian diver experiments, freshly killed copepods (Acanthocyclops vernalis) produced significant...

Thinking the unthinkable: does mental health nursing have a future?.

Molecular symmetry governs surface diffusion.

Physical review letters

Sonnleitner T, Swart I, Pavliček N, Pöllmann A, Repp J.
PMID: 22107649
Phys Rev Lett. 2011 Oct 28;107(18):186103. doi: 10.1103/PhysRevLett.107.186103. Epub 2011 Oct 27.

In chemistry and physics symmetry principles are all important, for example, leading to the selection rules governing optical transitions. We have investigated the influence of the molecular symmetry on the surface potential landscape of molecules in the limit of...

Effects of age, sex and arm on the precision of arm position sense-left-arm superiority in healthy right-handers.

Frontiers in human neuroscience

Schmidt L, Depper L, Kerkhoff G.
PMID: 24399962
Front Hum Neurosci. 2013 Dec 24;7:915. doi: 10.3389/fnhum.2013.00915. eCollection 2013.

Position sense is an important proprioceptive ability. Disorders of arm position sense (APS) often occur after unilateral stroke, and are associated with a negative functional outcome. In the present study we assessed horizontal APS by measuring angular deviations from...

Image distortions of a partially fluorinated hydrocarbon molecule in atomic force microscopy with carbon monoxide terminated tips.

Nano letters

Moll N, Schuler B, Kawai S, Xu F, Peng L, Orita A, Otera J, Curioni A, Neu M, Repp J, Meyer G, Gross L.
PMID: 25247477
Nano Lett. 2014 Nov 12;14(11):6127-31. doi: 10.1021/nl502113z. Epub 2014 Sep 30.

The underlying mechanisms of image distortions in atomic force microscopy (AFM) with CO-terminated tips are identified and studied in detail. AFM measurements of a partially fluorinated hydrocarbon molecule recorded with a CO-terminated tip are compared with state-of-the-art ab initio...

Facing the challenge: bringing brain-computer interfaces to end-users.

Confinement and interaction of single indirect excitons in a voltage-controlled trap formed inside double InGaAs quantum Wells.

Physical review letters

Schinner GJ, Repp J, Schubert E, Rai AK, Reuter D, Wieck AD, Govorov AO, Holleitner AW, Kotthaus JP.
PMID: 25166847
Phys Rev Lett. 2013 Mar 22;110(12):127403. doi: 10.1103/PhysRevLett.110.127403. Epub 2013 Mar 19.

Voltage-tunable quantum traps confining individual spatially indirect and long-living excitons are realized by providing a coupled double quantum well with nanoscale gates. This enables us to study the transition from confined multiexcitons down to a single, electrostatically trapped indirect...

Now You Feel both: Galvanic Vestibular Stimulation Induces Lasting Improvements in the Rehabilitation of Chronic Tactile Extinction.

Frontiers in human neuroscience

Schmidt L, Utz KS, Depper L, Adams M, Schaadt AK, Reinhart S, Kerkhoff G.
PMID: 23519604
Front Hum Neurosci. 2013 Mar 20;7:90. doi: 10.3389/fnhum.2013.00090. eCollection 2013.

Tactile extinction is frequent, debilitating, and often persistent after brain damage. Currently, there is no treatment available for this disorder. In two previous case studies we showed an influence of galvanic vestibular stimulation (GVS) on tactile extinction. Here, we...
