TL;DR: Several structural features of aqueous solutions of the ionic liquid 1-ethyl-3-methylimidazolium ethylsulfate were analyzed in the entire concentration range using molecular dynamics simulation results, identifying four distinct structural regimes--isolated water molecules, chain-like water aggregates, bicontinuous system, and isolated ions or small ion clusters.

TL;DR: The economical and environmental sustainability of the aqueous two-phase extraction process is evaluated and compared to the currently established protein A affinity chromatography and the ATPE process was shown to be considerably advantageous in terms of process economics.

TL;DR: In this article, the lightest SUSY particle is considered and it is shown that the neutralino decays inside the detector even for tiny neutrino masses and measurements of the neutrinos mixing angles lead to predictions for the ratios of various neutralino decay branching ratios implying an independent test of neutrini physics at future colliders, such as the CERN Large Hadron Collider or a Linear Collider.
Abstract: Low energy supersymmetry with bilinear breaking of R parity leads to a weak-scale seesaw mechanism for the atmospheric neutrino scale and a radiative mechanism for the solar neutrino scale. The model has striking implications for collider searches of supersymmetric particles. Assuming that the lightest SUSY particle is the lightest neutralino we demonstrate that (i) the neutralino decays inside the detector even for tiny neutrino masses and (ii) measurements of the neutrino mixing angles lead to predictions for the ratios of various neutralino decay branching ratios implying an independent test of neutrino physics at future colliders, such as the CERN Large Hadron Collider or a Linear Collider. We study the lightest neutralino decay branching ratio predictions taking into account present supersymmetric particle mass limits as well as restrictions coming from neutrino physics, with emphasis on the solar and atmospheric neutrino anomalies.

TL;DR: This paper addresses the problem of position and attitude estimation, based on landmark readings and velocity measurements, using a derivation of a nonlinear observer on SE(3) using a Lyapunov function conveniently expressed as a function of the difference between the estimated and the measured landmark coordinates.

TL;DR: The main definitions and formalizations of the affordance theory are discussed, the most significant evidence in psychology and neuroscience that support it are reported, and the most relevant applications of this concept in robotics are reviewed.
Abstract: The concept of affordances appeared in psychology during the late 60s as an alternative perspective on the visual perception of the environment. It was revolutionary in the intuition that the way living beings perceive the world is deeply influenced by the actions they are able to perform. Then, across the last 40 years, it has influenced many applied fields, e.g., design, human-computer interaction, computer vision, and robotics. In this paper, we offer a multidisciplinary perspective on the notion of affordances. We first discuss the main definitions and formalizations of the affordance theory, then we report the most significant evidence in psychology and neuroscience that support it, and finally we review the most relevant applications of this concept in robotics.
