Free heterogeneous argon-krypton clusters have been produced by coexpansion and investigated by means of x-ray photoelectron spectroscopy. By examining cluster surface and bulk binding energy shifts, relative intensities, and peak widths, we show that in the mixed argon-krypton clusters the krypton atoms favor the bulk and argon atoms are pushed to the surface. Furthermore, we show that krypton at

The use of algae as a feedstock for the production of advanced biofuels has tremendous potential because of its short growth cycle, high productivity, lack of competition for agricultural lands, ability to use a variety of water sources and recycle CO2 and nutrient emissions, and compatibility with existing fuels chains with minimum process changes. However, to make significant contributions to bi

Contemporary debates on sustainability usually relies on standardised and normative categories, such as ‘social’ and ‘nature’, and on linear notions of time. This study explores a more complex perspective on the delicate borderlands between the ‘un-sustainable’ and the ‘sustainable’. A particular material and a particular place stand at the centre of attention: woollen Merino fibre on the South Am

Familial risks for histopathology-specific cancers have not been determined. We used the nationwide Swedish Family-Cancer Database on 10.2 million individuals and 1 million tumors to calculate standardized incidence ratios (SIRs) for familial cancers of specific histology and morphology among 0- to 66-year-old offspring. We used histology codes for both offspring and parents, but because of the li

We consider the problem of seeking the maximum of a scalar signal using a swarm of autonomous vehicles equipped with sensors that can take point measurements of the signal. Vehicles are not able to measure their current position or to communicate with each other. Our approach induces the vehicles to perform a biased random walk inspired by bacterial chemotaxis and controlled by a stochastic hybrid

In the wake of the deterioration of relations between modern Russia and Poland, the Katyn memorial has become a scene for the contestation of historical memory. In order to play down the 1940 executions of Polish military officers in Katyn, the Russian government has granted belated official recognition to 8,000 victims of Stalinism in the Smolensk region. After being brushed under the carpet in t
