This paper presents a comparison of various ways to use a robotic system for building a wall. This task is analyzed in order to introduce a few optional systems that differ from each other by their level of autonomy and the task allocation between humans and the robot. An economic analysis is conducted in order to examine the profitability of each system. The economic implications are presented...

Zusammenfassung Der Beitrag setzt sich kritisch mit dem Prinzip des prokreativen Wohltuns ( principle of procreative beneficence , PB) von Julian Savulescu und seinen Implikationen für den Umgang der Präimplantationsdiagnostik (PID) auseinander. PB fordert angehende Eltern dazu auf, aus mehreren möglichen zukünftigen Kindern dasjenige auszuwählen, dessen Leben voraussichtlich am besten verlaufe...

Adhesins and adhesin-related accessory proteins of pathogenic mycoplasmas are required for cytadherence and the subsequent development of disease pathology. The classic example has been Mycoplasma pneumoniae, which causes primary atypical pneumonia in humans. Mutants of M. pneumoniae defective in adhesins (P1 and P30) or in adherence-accessory proteins (HMW1 through HMW4) are unable to colonize...

It is natural to expect that the arithmetic sum of two Cantor sets should have positive Lebesgue measure if the sum of their dimensions exceeds 1, but there are many known counterexamples, e.g. when both sets are the middle-α Cantor set and α ∈ ( 1 3 , 1 2 ). We show that for any compact set K and for a.e. α ∈ (0, 1), the arithmetic sum of K and the middle-α Cantor set does indeed have positive...

This survey paper is based on a talk given at the 44th Summer Symposium in Real Analysis Paris. line of research was initiated by question Haight and Weizsäker concerning almost everywhere convergence properties series form $\sum_{n=1}^{{\infty}}f(nx)$. A more general, additive version this problem following: Suppose $\Lambda$ discrete infinite set nonnegative real numbers. We say that $ {\Lamb...

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract Global Climate Models (GCMs) precipitation scenarios are often characterized by biases and coarse resolution that limit their direct application for basin level hydrological modeling. Bias-correction and spatial disaggregation methods are ...

In this paper we extend some classical results valid for canonical multiplicative cascades to exact scaling log-infinitely divisible cascades. We complete previous results on non-degeneracy and moments of positive orders obtained by Barral and Mandelbrot, and Bacry and Muzy: we provide a necessary and sufficient condition for the non-degeneracy of the limit measures of these cascades, as well a...

While the derived trees yielded by TAG derivations are uncontroversially taken to correspond to phrase structure, the status of TAG derivation structures as more than a record of TAG operations is less certain. An attractive possibility is to interpret the derivation structure as some representation of semantic meaning, such as a dependency analysis. However, the literature has identified cases...
