We present the Hamiltonian formulation of a relativistic point-particle coupled to Einstein gravity and its canonical quantization \`a la Wheeler-DeWitt. In resulting quantum theory, wave functional is function particle coordinates 3-metric. It satisfies particular diffeomorphism constraint, together with Klein-Gordon-type equation. As usual in Wheeler-DeWitt time-independent. This also reflect...

The paper addresses the quantization of minisuperspace cosmological models, with application to the Taub Model. By desparametrizing the model with an extrinsic time, a formalism is developed in order to define a conserved Schrödinger inner product in the space of solutions of the Wheeler-De Witt equation. A quantum version of classical canonical transformations is introduced for connecting the ...

⋆ Abstract. Compression algorithms and streaming algorithms are both powerful tools for dealing with massive data sets, but many of the best compression algorithms — e.g., those based on the Burrows-Wheeler Transform — at first seem incompatible with streaming. In this paper we consider several popular streaming models and ask in which, if any, we can compress as well as we can with the BWT. We...

In the above correspondence [1], Figs. 1–3 were inadvertently omitted in the post page-proof production process. The following were the affected figures.

Activated carbons can adsorb a wide variety of substances. This is the reason why they are used in canisters to guarantee the safety of the people. The use of the canisters is dependent on several parameters which makes it interesting if the safety margins of the filter can be predicted. The Wheeler-Jonas equation is a well-known predictive equation for describing organic vapour breakthrough ti...
