Capturing microbial growth on a macroscopic scale is of great importance to further our understanding of microbial life. However, methods for imaging microbial life on a scale of millimeters to centimeters are often limited by designs that have poor environmental control, resulting in dehydration of the agar plate within just a few days. Here, we created MOCHA (microbial chamber), a simple but ...

Local-structure scattering refinements using a simultaneous fit of x-ray/neutron total scattering, EXAFS, and diffuse scattering in electron diffraction are implemented as an extension to the RMCProfile software Version 6. Users should refer to the main RMCProfile manual for this version for details regarding RMC refinements using total scattering data alone. A user is expected to have a reason...

The automotive marketplace has seen a steady increase in customer demands for quiet and more comfortable vehicles. A customer’s expectations for NVH refinement often contradicts the constraints for lightweight vehicle designs and the need for a powertrain with increased fuel efficiency. The driveline of a vehicle can be a substantial cause of NVH issues. Variants in the driveline architecture (...

Laser-plasma technology promises a drastic reduction of the size of high-energy electron accelerators. It could make free-electron lasers available to a broad scientific community and push further the limits of electron accelerators for high-energy physics. Furthermore, the unique femtosecond nature of the source makes it a promising tool for the study of ultrafast phenomena. However, applicati...

The coupled transport of heat and electrical current, or thermoelectric phenomena, can strongly influence the temperature distribution and figures of merit for phase-change memory (PCM). This paper simulates PCM devices with careful attention to thermoelectric transport and the resulting impact on programming current during the reset operation. The electrothermal simulations consider Thomson he...

Critical phenomena have been greatly in evidence in recent years, especially last year in view of the Nobel Prize being awarded to K. G. Wilson for his Renormalization-Group (R.G.) theory (1). With this theory, one can quantitatively calculate the response of cooperative systems undergoing phase transitions, be they of the continuous, second-order, or discontinuous, first-order, variety. Especi...

Analytical description of propagation phenomena on random networks has flourished in recent years, yet more complex systems have mainly been studied through numerical means. In this paper, a mean-field description is used to coherently couple the dynamics of the network elements (such as nodes, vertices, individuals, etc.) on the one hand and their recurrent topological patterns (such as subgra...

We present a mesoscopic model for thermoelectric phenomena in terms of an interacting particle system, a lattice electron gas dynamics that is a suitable extension of the standard simple exclusion process. We concentrate on electronic heat and charge transport in different but connected metallic substances. The electrons hop between energy-cells located alongside the spatial extension of the me...

The separation between molecular and mesoscopic length and time scales poses a severe limit to molecular simulations of mesoscale phenomena. We describe a hybrid multiscale computational technique which addresses this problem by keeping the full molecular nature of the system where it is of interest and coarse graining it elsewhere. This is made possible by coupling molecular dynamics with a me...

Despite a lot of knowledge about complex systems the application of this knowledge to the engineering domain remains difficult. Efforts are scattered over many scientific and engineering disciplines. In this contribution we would like to motivate the union of these efforts by establishing complexity engineering as a discipline. We will motivate this initiative and show a few aspects that we con...
