Augmenting probabilities to conditional logic yields an expressive mechanism for representing uncertainty. The principle of optimum entropy allows one to reason in probabilistic logic in an information-theoretic optimal way by completing the given information as unbiasedly as possible. In this paper, we introduce the MECoRe system that realises the core(More)
Keywords: Spectral geometry processing Vector bundles Computational topology Laplace operator Finite elements a b s t r a c t Computing the spectral decomposition of the Laplace–Beltrami operator on a manifold M has proven useful for applications such as shape retrieval and geometry processing. The standard operator acts on scalar functions which can be(More)
In the present work, we extend the theoretical and numerical discussion of the well-known Laplace–Beltrami operator by equipping the underlying manifolds with additional structure provided by vector bundles. Focusing on the particular class of flat complex line bundles, we examine a whole family of Laplacians including the Laplace–Beltrami operator as a(More)
Designing soft robots is difficult, time-consuming, and non-intuitive. Soft robot design faces two main challenges: structure and control. This research uses generative encodings to grow structures and a vibrational mechanism to control locomotion. In this paper, we demonstrate the ability to successfully evolve soft robots that can move when vibrated. Soft(More)
1. Electrically evoked release of [3H]-noradrenaline ([3H]-NA) or [3H]-5-hydroxytryptamine ([3H]-5-HT) in slices of human and the rat neocortex was used to characterize presynaptic opioid receptors. 2. Release of [3H]-NA in rat neocortical slices was reduced only by the mu-receptor agonist DAMGO (pIC50: 7.27, CI95: [7.22, 7.32]; Imax: 77.6+/-1.6%;(More)
The just war tradition usually revolves around two crucial points: the justness of a war, and the justness of the way that war is fought. These two points—jus ad bellum and jus in bello, respectively—define the debate over whether a war is moral. Much less has been said about what happens after a war. But the aftermath of war is crucial to the justice of(More)
BACKGROUND AND OBJECTIVE Activity of human cytochrome P450 enzymes (CYPs) shows high inter-and intra-individual variability, which is determined by genetic and non-genetic factors. Using a combination of CYP-specific probe drugs, phenotyping cocktails allow simultaneous assessment of the activity of different CYP isoforms. The objective of this study was to(More)
Eigenvalue spectra of the Laplace-Beltrami operator have successfully been employed as fingerprints for shape and image comparison. Especially notable in this context is the work of Peinecke on Laplace spectrum fingerprinting for image data. Recently, new research on greyscale images by Berger et al. introduces the idea of attributing individual(More)
BACKGROUND The analysis of cerebrospinal fluid (CSF) is usually done under steady-state conditions, when proteins (e.g., immunoglobulins) reach diffusion equilibrium between blood and CSF. However, little data has been published on CSF analysis under non-steady-state conditions after therapeutic apheresis. By reducing serum proteins (e.g., immunoglobulins),(More)
Designing soft robots is difficult, time-consuming, and non-intuitive. Instead of requiring humans to engineer robots, this research uses genetic algorithms to evolve designs for robots that move when vibrated. Generative encodings are used to represent designs and are modified during the evolutionary process. A generative encoding is a set of rules that(More)
