The geometric formulation of the Dirac theory with spacetime algebra is shown to be equivalent to the usual matrix formalism. Imaginary numbers in the Dirac theory are shown to be related to the spin tensor. The relation of observables to operators and the wavefunction is analyzed in detail and compared with some purportedly general principles of quantum mechanics. An exact formulation of Larmo...

—An overview is provided of a symposium on the direction of research and management of Doublecrested Cormorants (Phalacrocorax auritus) heading into the 2000s. The current symposium built on previous efforts and described a number of focus areas of informational need, including cormorant impacts on natural resources, demographics of cormorants, assessment of control efforts, assessment of fish ...

Whereas decoherence has been much studied theoretically, little attention was given to the difference between the full quantum density matrix and the decoherent one. Although inaccessible to experiment, it never vanishes and keeps in principle a phase memory of everything in the past. Its investigation is applied here to the influence of the external universe on a macroscopically isolated syste...

this paper seeks to investigate a new definition for architecture by unifying the three vitruvian principles of firmitas, utilities, and venustas via a phenomenological approach in the interpretation and analysis of their role in defining architecture. the paper is composed in two main sections. the first section investigates the nature of architecture based on the mentioned principles, where a...

The neutral kaon system offers a unique possibility to perform fundamental tests of CPT invariance, as well as of the basic principles of quantum mechanics. The most recent limits obtained by the KLOE experiment at the DAΦNE e+e− collider on several kinds of possible CPT violation and decoherence mechanisms, which in some cases might be justified in a quantum gravity framework, are reviewed. No...

Classical model SDcl of the Dirac particle SD is constructed. SD is the dynamic system described by the Dirac equation. For investigation of SD and construction of SDcl one uses a new dynamic method: dynamic disquantization. This relativistic purely dynamic procedure does not use principles of quantum mechanics. The obtained classical analog SDcl is described by a system of ordinary differentia...

Using Spencer-Oatey’s (2004, 2008) Rapport Management approach, this study was conducted to elicit the reprimanding response behavior of native Persian speakers and EFL Learners. The participants of this study were 30 native Persian speakers and 60 EFL learners. To fulfill the purposes of this study, a six-binary situation Interactive Discourse Completion (IDCT) Task was utilized. Emotion Liker...

The hierarchy of separation axioms that is familiar from topological spaces generalizes to spaces with an isotone and expansive closure function. Neither additivity nor idempotence of the closure function must be assumed.
