Guppies Prefer to Follow Large (Robot) Leaders Irrespective of Own Size

Bierbach, David ; Mönck, Hauke J. ; Lukas, Juliane ; Habedank, Marie ; Romanczuk, Pawel ; Landgraf, Tim ; Krause, Jens (2020-05-15)

Body size is often assumed to determine how successfully an individual can lead others with larger individuals being better leaders than smaller ones. But even if larger individuals are more readily followed, body size often correlates with specific behavioral patterns and it is thus unclear whether larger individuals are more often followed than smaller ones because of their size or because th...

Symbole und Räume

Knoblauch, Hubert (2020-05)

Ausgehend von der These, dass die Corona-Krise als ein Konflikt zweier Raumfigurationen zu erklären ist widmet sich dieser Beitrag der Frage, ob und inwiefern gerade die massiven Schließungen als eine Art symbolische Politik verstanden werden können. Denn in der Tat dienen die massiven Raum-Schließungen der Kommunikation zwischen einer nun in einer ebenso massiv asymmetrischen Führungsposition ...

Black Mice Dataset v1

Hohlbaum, Katharina ; Andresen, Niek ; Wöllhaf, Manuel ; Lewejohann, Lars ; Hellwich, Olaf ; Thöne-Reineke, Christa ; Belik, Vitaly (2019)

The “Black Mice Dataset” is a large set of images of C57BL/6JRj mice and a corresponding “well-being” label. It encompasses images of mice that have (or have not) undergone different procedures that impaired their well-being. Images were taken at different points in time before and after the procedures. The images were obtained within the framework of a project, in which the impact of procedure...

On the Temporalities and Spatialities of the Production of Space

Frehse, Fraya (2020-01)

Since the 1950s, sociology has embraced various theoretical frameworks for coping with the spatialization of social phenomena, which from the 1970s has often been named “the production of space”. The present paper uses these approaches as an opportunity to examine which conceptual insights into the process at hand can be gained by addressing in four analytical steps what time, particularly, dis...

Rivers are important ecosystems under continuous anthropogenic stresses. The hyporheic zone is a ubiquitous, reactive interface between the main channel and its surrounding sediments along the river network. We elaborate on the main physical, biological, and biogeochemical drivers and processes within the hyporheic zone that have been studied by multiple scientific disciplines for almost half a...

Apples and oranges : a methodological framework for basic research into audiovisual perception

Maempel, Hans-Joachim (2019)

In recent years, increased efforts have been made to investigate the various aspects of audiovisual perception. In general, highly-specific variables are considered, and specific paradigms and methods are applied. Thus, connecting results of various experiments is not always possible in a systematic manner, and several related research fields still lack comprehensive theories and corresponding ...

Numerical Assessment of Virtual Control Surfaces for Load Alleviation on Compressor Blades

Motta, Valentina ; Malzacher, Leonie ; Peitsch, Dieter (2018-01-17)

Virtual control surfaces for the optimization of steady and unsteady airloads on a compressor cascade are assessed numerically. The effects of mechanical surfaces are realized with plasma actuators, located both on the pressure and on the suction side of the blade trailing edge. Suction side plasma actuation is thought to reproduce the effects of mechanical wing spoilers, whereas pressure side ...

Water and heat transport of paved surfaces

Timm, Anne (2019)

The urban soil-atmosphere is typically paved with varying materials. This alteration has drastic effects on the urban hydrological balance. With a focus on stormwater management, most existing models treat all types of pavements identically when estimating runoff and neglect losses caused by evaporation and infiltration processes. A literature review reveals that very few studies have been publ...

Adapting the water management to mitigate the impact of multiple stressors on an urban lake

Ladwig, Robert (2019)

Urban lakes are aquatic ecosystems that are influenced by a water management system and by a possibly strongly sealed urban catchment. The water management aims to fulfill multiple objectives: providing drinking water, sanitation and recreation for the people as well as keeping the ecosystem in a sustainable and resilient state. Urban lakes are facing several stressors. For instance, climate ch...

Evaluating the Impact of Wastewater Effluent on Microbial Communities in the Panke, an Urban River

Nega, Marcella ; Braun, Burga ; Künzel, Sven ; Szewzyk, Ulrich (2019-04-28)

Pharmaceuticals are consumed in high amounts and can enter as emerging organic compounds in surface waters as they are only partially retained in wastewater treatment plants (WWTPs). Receiving pharmaceuticals may burden the aquatic environment, as they are designed to be bioactive even at low concentrations. Sediment biofilm populations were analyzed in river sediments due to the exposure of an...

Estimating Pore Water Electrical Conductivity of Sandy Soil from Time Domain Reflectometry Records Using a Time-Varying Dynamic Linear Model

Aljoumani, Basem ; Sanchez-Espigares, Jose A. ; Wessolek, Gerd (2018-12-13)

Despite the importance of computing soil pore water electrical conductivity (σp) from soil bulk electrical conductivity (σb) in ecological and hydrological applications, a good method of doing so remains elusive. The Hilhorst concept offers a theoretical model describing a linear relationship between σb, and relative dielectric permittivity (εb) in moist soil. The reciprocal of pore water elect...

Reducing global CO2 emissions with the technologies we have

Ward, Hauke ; Radebach, Alexander ; Vierhaus, Ingmar ; Fügenschuh, Armin ; Steckel, Jan Christoph (2017)

The energy intensities of the various industrial sectors differ considerably across countries. This suggests a potential for emissions reductions through improved accessibility to efficient technologies. This paper estimates an upper-bound CO2 emission mitigation potential that could theoretically be achieved by improved access to efficient technologies in industrial sectors. We develop a linea...

Wolff, Sascha Dominik (2019)

Aktuelle Forschungsbestrebungen zur Effizienzsteigerung von Gasturbinen verfolgen häufig den Ansatz eines Wechsels des zugrundeliegenden Kreisprozesses weg vom Brayton- hin zum Humphrey-Kreisprozess. Eine vielversprechende Möglichkeit, diesen Kreisprozess technischzu realisieren, ist durch den Einsatz einer pulsierenden, druckerhöhenden Detonationsbrennkammer gegeben. Eine solche Brennkammer be...

Compressible starting jet: pinch-off and vortex ring–trailing jet interaction

Peña Fernández, Juan José ; Sesterhenn, Jörn (2017)

The dominant feature of the compressible starting jet is the interaction between the emerging vortex ring and the trailing jet. There are two types of interaction: the shock–shear layer–vortex interaction and the shear layer–vortex interaction. The former is clearly not present in the incompressible case, since there are no shocks. The shear layer–vortex interaction has been reported in the lit...

Statistics of fully turbulent impinging jets

Wilke, Robert ; Sesterhenn, Jörn (2017)

Direct numerical simulations (DNS) of subsonic and supersonic impinging jets with Reynolds numbers of 3300 and 8000 are carried out to analyse their statistical properties with respect to heat transfer. The Reynolds number range is at low or moderate values in terms of practical applications, but very high regarding the technical possibilities of DNS. A Reynolds number of 8000 is technically re...
