A general discussion is given for first-kind (FK) and quantum non-demolition (QND) measurements. The general conditions for these measurements are derived, including the most general one (called the weak condition), an intermediate one, and the strongest one. The weak condition indicates that we can realize a FK or QND measuring apparatus of wide classes of observables by allowing the apparatus...

Assuming an average latency of 42 years, the authors predict that incidence rates will peak in 2009 and that diagnoses will peak in 2014. However, they caution that ongoing use of chrysotile asbestos (which has been implicated but not conclusively established as a cause of mesothelioma) and the release of asbestos fibers from older buildings during demolition or reno­ vation may slow the projec...

Dedicated to Heinz Dehnen in honour of his 65 birthday. In this work we obtain a family of quantum nondemolition variables for the case of a particle moving in an inhomogeneous gravitational field. Afterwards, we calculate the corresponding propagator, and deduce the probabilities associated with the possible measurement outputs. The comparison, with the case in which the position is being moni...

In this paper we discuss the motivation, the technology, the design and the use-model of a novel web service for quantity surveyors, aiming to exploit virtual and augmented reality methods to implement a “zero waste” model, i.e. a new design paradigm where the waste materials from demolition become resources for reconstruction. The goal of this project is to provide virtual/augmented reality to...

We report the development of a fast pulse polarimeter for the application to quantum non-demolition measurement of atomic spin (Spin QND). The developed system was tunable to the atomic resonance of ytterbium atom and has narrow laser linewidth suitable for spin QND. Using the developed polarimeter, we successfully demonstrated the measurement of the vacuum noise, with 10 to 10 photon number pe...

The current situation in Russia, the United States, the Middle East and many other countries, clearly highlights the problem of the war against terrorism. Today’s terrorism is neither desperate nor isolated. In Russia it is amply financed, well led and efficiently organized into battalions, companies, platoons and squads. The terrorist organization here in Russia includes all the essential mili...

THE LISTER WARD AND LISTER'S CENTENARY. Although the managers of the Glasgow Royal Infirmary, as we noted in our November issue, have decided to destroy the famous Lister Ward, and it is understood that tenders have actually been accepted for its demolition, Mr. James A. Morris, F.R.I.B.A., has followed his admirable " Humble Plea " for its retention with another pamphlet, believing that at the...
