Like other STEM fields, computer science (CS) lacks representation of minorities, such as Black and Hispanic individuals, both in the number of bachelor's degrees obtained and the number of individuals in the CS workforce. Out-of-school CS programs are often...

Non-polymeric asymmetric binary glass-formers. II. Secondary relaxation studied by dielectric, .

The Journal of chemical physics

Pötzschner B, Mohamed F, Bächer C, Wagner E, Lichtinger A, Bock D, Kreger K, Schmidt HW, Rössler EA.

J Chem Phys. 2017 Apr 28;146(16):164504. doi: 10.1063/1.4980085.

We investigate the secondary (β-) relaxations of an asymmetric binary glass former consisting of a spirobichroman derivative (SBC; T

Host response during Yersinia pestis infection of human bronchial epithelial cells involves negative regulation of autophagy and suggests a modulation of survival-related and cellular growth pathways.

Yersinia pestis (Yp) causes the re-emerging disease plague, and is classified by the CDC and NIAID as a highest priority (Category A) pathogen. Currently, there is no approved human vaccine available and advances in early diagnostics and effective therapeutics...

Long-range energy transport in single supramolecular nanofibres at room temperature.

Nature

Haedler AT, Kreger K, Issac A, Wittmann B, Kivala M, Hammer N, Köhler J, Schmidt HW, Hildner R.
PMID: 26156373
Nature. 2015 Jul 09;523(7559):196-9. doi: 10.1038/nature14570.

Efficient transport of excitation energy over long distances is a key process in light-harvesting systems, as well as in molecular electronics. However, in synthetic disordered organic materials, the exciton diffusion length is typically only around 10 nanometres (refs 4,...

The effect of constructing versus solving virtual patient cases on transfer of learning: a randomized trial.

Perspectives on medical education

Tolsgaard MG, Jepsen RM, Rasmussen MB, Kayser L, Fors U, Laursen LC, Svendsen JH, Ringsted C.
PMID: 26754313
Perspect Med Educ. 2016 Feb;5(1):33-8. doi: 10.1007/s40037-015-0242-4.

The purpose of this study was to explore the effect of actively constructing virtual patient (VP) cases compared with solving VP cases on knowledge gains, skills transfer and time spent on cases. Forty-five fourth-year medical students were randomized to...

Abnormal rolls and regular arrays of disclinations in homeotropic electroconvection.

Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics

Rossberg AG, Eber N, Buka A, Kramer L.
PMID: 11046364
Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 2000 Jan;61(1):R25-8. doi: 10.1103/physreve.61.r25.

We present the first quantitative verification of an amplitude description for systems with (nearly) spontaneously broken isotropy, in particular for the recently discovered abnormal-roll states. We also obtain a conclusive picture of the three-dimensional director configuration in a spatial...

Domain segregation in a two-dimensional system in the presence of drift.

Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics

Bragard J, Ramazza PL, Arecchi FT, Boccaletti S, Kramer L.
PMID: 11088346
Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 2000 Jun;61(6):R6045-8. doi: 10.1103/physreve.61.r6045.

Motivated by experiments on optical patterns we analyze two-dimensional extended bistable systems with drift after a quench above threshold. The evolution can be separated into successive stages: linear growth and diffusion, coarsening, and transport, leading finally to a quasi-one-dimensional...

Magnetic field effect on the thresholds of a sequence of transitions in the electroconvection of a homeotropic nematic liquid crystal.

Physical review. E, Statistical, nonlinear, and soft matter physics

Eber N, Németh S, Rossberg AG, Kramer L, Buka A.
PMID: 12366230
Phys Rev E Stat Nonlin Soft Matter Phys. 2002 Sep;66(3):036213. doi: 10.1103/PhysRevE.66.036213. Epub 2002 Sep 23.

We present a detailed analysis of the characteristics of electroconvection patterns in a homeotropic nematic liquid crystal under the influence of a variable magnetic field. An unambiguous observation of low frequency "reentrant" normal rolls and a nonmonotonic magnetic field...

Modulated structures in electroconvection in nematic liquid crystals.

Motivated by experiments in electroconvection in nematic liquid crystals with homeotropic alignment we study the coupled amplitude equations describing the formation of a stationary roll pattern in the presence of a weakly damped mode that breaks isotropy. The equations...

The Ginzburg-Landau approach to oscillatory media.

Chaos. 1994 Sep;4(3):443-452. doi: 10.1063/1.166022.

Close to a supercritical Hopf bifurcation, oscillatory media may be described, by the complex Ginzburg-Landau equation. The most important spatiotemporal behaviors associated with this dynamics are reviewed here. It is shown, on a few concrete examples, how real chemical...
