Differential evolution in shortest path problems

open access: yes, 2011
This paper proves that the Di erential Evolution (DE) algorithm is valid to solve the Shortest Path (SP) problem in random, median sized networks. From the trials, we have obtained an 9% accuracy, in the worst case scenario.

Effective Manipulation of Water Droplets on Open Superhydrophobic Glass Surfaces by Using a Triboelectrically Charged Polytetrafluoroethylene Rod on the Back Side of These Surfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
The movement of pure water droplets on a superhydrophobic glass surface is precisely controlled through electrostatic manipulation using a polytetrafluoroethylene (PTFE) rod from the opposite side. With just a few seconds of triboelectric charging, the PTFE rod directs droplets, achieving acceleration over 10 000 mm s−2.

Variants of the Shortest Path Problem [PDF]

open access: yes, 2011
The shortest path problem in which the \((s,t)\)-paths \(P\) of a given digraph \(G =(V,E)\) are compared with respect to the sum of their edge costs is one of the best known problems in combinatorial optimization. The paper is concerned with a number of variations of this problem having different objective functions like bottleneck, balanced, minimum ...

Biological and Mechanical Limitations for Chronic Fast‐Scan Cyclic Voltammetry Sensor Design

open access: yesAdvanced Materials Technologies, EarlyView.
Real‐time detection of neurochemicals has demonstrated value in the field of neuroscience. However, current methods have limitations for use in the chronic setting, which is often the ideal environment for research. This article discusses these limitations, as well as technologies that have been developed to overcome them, and provides recommendations ...

Progress in Flexible Perovskite Solar Cells: Paving the Way for Scalable Manufacturing

open access: yesAdvanced Materials Technologies, EarlyView.
Perovskite solar cells (PSCs) are well positioned for a successful market uptake. This is due to an unprecedented improvement of their efficiency and stability since the first report in 2009. In this review paper, the building blocks for the scalable manufacturing and future commercialization of flexible PSCs and their pathway to impact will be ...
