Actively propelled particles undergoing dissipative collisions areknown to develop a state of spatially distributed coherently moving clusters.For densities larger than a characteristic value, clusters grow in time and forma stationary well-

Stability of Localized Wave Fronts in Bistable Systems

Jan 1st, 2013

Localized wave fronts are a fundamental feature of biological systems from cell biology to ecology. Here, we study a broad class of bistable models subject to self-activation, degradation, and spatially inhomogeneous activating agents. We deter

Klärung des Informationsbegriffs

Jan 1st, 2013

Eine naturphilosophische Leitwährung für die Beschreibung der Wirlichkeit ist bereits bei Aristoteles die Form. Sie informiert die Materie und vermittelt dadurch das Sein.Der Informationsbegriff jedoch ist multivalent: man kann zwischen poten

Increasing organic solar cell efficiency with polymer interlayers

Nov 7th, 2012

We demonstrate how organic solar cell efficiency can be increased by introducing a pure polymer interlayer between the PEDOT:PSS layer and the polymer: fullerene blend. We observe an increase in device efficiency with three different material s

Nucleation-induced transition to collective motion in active systems

Sep 1st, 2012

While the existence of polar ordered states in active systems is well established, the dynamics of the self-assembly processes are still elusive. We study a lattice gas model of self-propelled elongated particles interacting through excluded vo

Microtubule Length Regulation by Molecular Motors

Jun 1st, 2012

Length regulation of microtubules (MTs) is essential for many cellular processes. Molecular motors like kinesin-8, which move along MTs and also act as depolymerases, are known as key players in MT dynamics. However, the regulatory mechanisms o

Extinction in neutrally stable stochastic Lotka-Volterra models

May 1st, 2012

Populations of competing biological species exhibit a fascinating interplay between the nonlinear dynamics of evolutionary selection forces and random fluctuations arising from the stochastic nature of the interactions. The processes leading to

Validity of the Law of Mass Action in Three-Dimensional Coagulation Processes

Mar 1st, 2012

Diffusion-limited reactions are studied in detail on the classical coalescing process. We demonstrate how, with the aid of a recent renormalization group approach, fluctuations can be integrated systematically. We thereby obtain an exact relati

Growth dynamics and the evolution of cooperation in microbial populations

Feb 21st, 2012

Microbes providing public goods are widespread in nature despite running the risk of being exploited byfree-riders. However, the precise ecological factors supporting cooperation are still puzzling. Followingrecent experiments, we consider th

AGN Triggering in the Infall Regions of Distant X-Ray Luminous Galaxy Clusters at 0.9 < z less than or similar to 1.6

Jan 1st, 2012

Observational constraints on the average radial distribution profile of AGN in distant galaxy clusters can provide important clues on the triggering mechanisms of AGN activity in dense environments and are essential for a completeness evaluatio

Hydrodynamic deformation reveals two coupled modes/time scales of red blood cell relaxation

Jan 1st, 2012

We study the mechanical relaxation behavior of human red blood cells by observing the time evolution of shape change of cells flowing through microchannels with abrupt constrictions. We observe two types of relaxation processes. In the first fa

Highly Canalized MinD Transfer and MinE Sequestration Explain the Origin of Robust MinCDE-Protein Dynamics

Jan 1st, 2012

Min-protein oscillations in Escherichia coli are characterized by the remarkable robustness with which spatial patterns dynamically adapt to variations of cell geometry. Moreover, adaption, and therefore proper cell division, is independent of

Amyloid-Like Structures Formed by Azobenzene Peptides: Light-Triggered Disassembly

Jan 1st, 2012

The light-driven disassembly process of amyloid-like structures formed by azobenzene model peptides is studied by time-resolved mid-IR spectroscopy from nanoseconds to minutes. The investigated peptide consists of two amino acid strands connect

Semiconductor nanowires self-assembled from colloidal CdTe nanocrystal building blocks: optical properties and application perspectives

Jan 1st, 2012

Solution-based self-assembly of quasi-one-dimensional semiconductor nanostructures (nanowires) from quasi-zero-dimensional (quantum dots) colloidal nanocrystal building blocks has proven itself as a powerful and flexible preparation technique.

Do Nuclear Star Clusters and Supermassive Black Holes Follow the Same Host-Galaxy Correlations?

Jan 1st, 2012

Studies have suggested that there is a strong correlation between the masses of nuclear star clusters (NSCs) and their host galaxies, a correlation which is said to be an extension of the well-known correlations between supermassive black holes
