A derivation of the classical jump rate I' for tracer diffusion aimed at a clear expression for the mass dependence of the frequency factor v is presented. The derivation is effected without using the usual collective normal coordinates which usually combine the masses in a complicated way. v depends explicitly on the mass of the surrounding host atoms (as well as on the tracer-atom mass) if th...

We perform transport measurements in high quality bilayer graphene pnp junctions with suspended top gates. At a magnetic field B = 0, we demonstrate band gap opening by an applied perpendicular electric field with an On/Off ratio up to 20,000 at 260 mK. Within the band gap, the conductance decreases exponentially by 3 orders of magnitude with increasing electric field and can be accounted for b...

The perturbation-theory study of universal conductance fluctuations is generalized to systems with electron scattering in a static random magnetic field. Our calculation confirms the intuitive expectation that the amplitude of Quctuations coincides with the universal value typical for the unitary random-scattering ensemble. An application of this result to micrometer-size wires with the two-dlm...

The results of pitfall trapping are often interpreted as abundance in a particular habitat. At the same time, there are numerous cases of almost unrealistically high catches of ground beetles in seemingly unsuitable sites. The correlation of catches by pitfall trapping with the true distribution and abundance of Carabidae needs corroboration. During a full year survey in 2006/07 in the Lake Elt...

Recent work from this laboratory has been concerned with elucidating the function of the non-thrombin-forming half or propiece of prothrombin in the zymogen activation process. These studies have demonstrated that Fragment 1, the NH2-terminal region of the propiece (Fragment 1.2), is responsible for the Ca2+-mediated binding of prothrombin to phospholipid vesicles (1) and that Fragment 2, the C...

Cambridge II (A384S) is a highly prevalent antithrombin variant in the British population (1.14 per 1000) and predisposes carriers to a mild but significant increased risk of thrombosis. To determine if the association of Cambridge II with thrombophilia is due to a perturbation of the antithrombin inhibitory mechanism, we expressed and characterized the variant. Antithrombin Cambridge II was fo...
