Partial-transfer absorption imaging is a tool that enables optimal imaging of atomic clouds for a wide range of optical depths. In contrast to standard absorption imaging, the technique can be minimally destructive and can be used to obtain multiple successive images of the same sample. The technique involves transferring a small fraction of the sample from an initial internal atomic state to a...

We propose a process algebra, the Algebra of Behavioural Types. A type is a higher-order labelled transition system that characterises all possible life cycles of a concurrent object. States represent interfaces of objects; state transitions model the dynamic change of object interfaces. Moreover, a type provides an internal view of the objects that inhabit it: a synchronous one, since transiti...

Using recoilless Mossbauer spectroscopy methods, we investigate the atomic absorption spectra of the 14.4keV transition in Fe compounds. The natural linewidth of this transition is determined to the correct order of magnitude with χν = .75. Hyperfine energy shifts in iron oxide and iron sulfate are investigated and measured. The ratio of ground and excited state magnetic moment in Fe is found t...

Metallo-β-lactamases (MβL) catalyzing the hydrolytic cleavage of the four-membered β-lactam ring in broad spectrum of antibiotics and therefore inactivating the drug; However, the mechanism of these enzymes is still not well understood. Electronic structure and electronic energy of metallo-β-lactamase active center, two inhibitors of this enzyme including penicillin and cephalexin, and differen...

Abstroer-A model far discrete-time dynamical systems is discussed in which are more naturally described by a set of higher order which the future values of the internal variables depend on the present and differential equations involving the internal and K I previous time instants, where Kis the order of the model. We outline the input, transition matrix and impulse response calculations, equiv...

Algorithms for (nondeterministic) finite-state tree automata (FTAs) are often tested on random FTAs, in which all internal transitions are equiprobable. The run-time results obtained in this manner are usually overly optimistic as most such generated random FTAs are trivial in the sense that the number of states of an equivalent minimal deterministic FTA is extremely small. It is demonstrated t...

Stresses for the elastic-plastic transition and fully plastic state have been derived for a thin rotating disc with inclusion and results have been discussed numerically and depicted graphically. It has been observed that the rotating disc with inclusion and made of compressible material requires lesser angular speed to yield at the internal surface whereas it requires higher percentage increas...
