Extractable entanglement from a Euclidean hourglass

On the dynamics of maximum extractable entanglement for open systems

In this work we study the dynamics of the maximum extractable entanglement for a system composed of two qubits interacting either with two independent thermal baths, a common thermal bath or a common squeezed bath. The states with maximum entanglement are found applying filtering operations which transform each state to a state in Bell diagonal form. We observe a revival of the maximum extracta...

Hourglass Automata

In this paper, we define the class of hourglass automata, which are timed automata with bounded clocks that can be made to progress backwards as well as forwards at a constant rate. We then introduce a new clock update for timed automata that allows hourglass automata to be expressed. This allows us to show that language emptiness remains decidable with this update when the number of clocks is ...

Hourglass Systems

In this paper, we first describe a simplified scenario observed in mining operations, where trucks are loaded and emptied at different locations. We will then look at ways that we can model this subsystem using timed automata so we may be able to apply model checking techniques on such systems. Specifically, we will look at modifications to the Hourglass Automata and Interrupt Timed Automata to...

A Sarcoma-Producing Factor Extractable from Transplanted Rat Fibrosarcomas*

A number of investigators (Schabad, Menke, Kleinenburg, and Steiner) have reported the extraction of fat-soluble tumor;producing substances from human tumors and also from the liver of human beings afflicted with neoplasms. The injection of the extracted fatty compound into mice and rats, however, produced tumors in only a small percentage of the treated animals. There were available a number o...
