The chemical composition of the solid grains from comet Halley can be inferred from impact-ionization time-of-flight mass spectrometry. Halley's dust in the vicinity of the VEGA-1 spacecraft is a mixture of a refractory organic component and unequilibrated silicates, bu...

We present a nonlinear approach based on the perturbation theory to analyze the synchronized oscillations in circuits made up of two coupled LC differential oscillators (LC-VCO), widely used in RF systems to generate quadrature oscillations. Closed-form expressions are ...

It is well documented that ancient sickle harvesting led to tough rachises, but the other seed dispersal properties in crop progenitors are rarely discussed. The first steps toward domestication are evolutionary responses for the recruitment of humans as dispersers. See...

We study the average-case running-time of single-source shortest-path (SSSP) algorithms assuming arbitrary directed graphs with n nodes, m edges, and independent random edge weights uniformly distributed in [0,1]. We give the first label-setting and label-correcting alg...

Proteolysis of hen egg-white lysozyme by thermolysin in 50% aqueous trifluoroethanol for 6–24 h at 40–52 °C produces a ‘nicked’ protein species which was purified to homogeneity by reverse-phase HPLC and characterized. Protein chemistry analytical methods were used to e...

a b s t r a c t Several multi-year biodiversity experiments have shown positive species richness-productivity rela- tionships which strengthen over time, but the mechanisms which control productivity are not well understood. We used experimental grasslands (Jena Experim...

In this paper we introduce a calibration procedure for validating of agent based models. Starting from the well-known financial model of (Brock and Hommes, 1998), we show how an appropriate calibration enables the model to describe price time series. We formulate the ca...

Abstract This paper questions the long-established view in the Musgrave-Samuelson public goods theory about voters’ incentives to misrepresent their preferences for public goods. The arguments are structured as follows: The concept of‘democracy’ as ‘government by the pe...

The common-mode voltage induced by an external plane-wave field in the terminal loads of a bundle of twisted-wire pairs (TWPs) is investigated. In particular, a deterministic bundle is firstly considered (i.e., a bundle with TWPs running parallel each other), and the di...

This article describes an investigation of the American Girl brand that provides a more complete and holistic understanding of sociocultural branding. Recent research on emotional branding, together with prior work on brands’ symbolic nature and their role as relations...
