Operational Phase Operators and Hermitian Phase Operators [PDF]

open access: yesProgress of Theoretical Physics, 2003
Summary: It is shown that there exist two kinds of operational (or measured) phase operators, those of the Hradil type [\textit{Z. Hradil}, Phys. Rev. A 47, 4532--4534 (1993)] defined on the entire Hilbert space, and those of the Noh-Fougères-Mandel type [\textit{J. W. Noh, A. Fougères} and \textit{L. Mandel}, Phys. Rev.

The operation $ABA$ in operator algebras [PDF]

open access: yesCommentationes Mathematicae Universitatis Carolinae, 2021
Summary: The binary operation \(aba\), called Jordan triple product, and its variants (such as e.g. the sequential product \(\sqrt{a}b\sqrt{a}\) or the inverted Jordan triple product \(ab^{-1}a\)) appear in several branches of operator theory and matrix analysis. In this paper we briefly survey some analytic and algebraic properties of these operations,

Invasive alien plants at Capraia Island (Italy): distribution and threats to Natura 2000 habitats [PDF]

open access: yesPlant Sociology
Island ecosystems face significant threats from biological invasions due to their unique biomes. In over a quarter of these ecosystems, the number of alien plants surpasses the total count of native ones, leading to notable impacts.

Operator Ideals and Operator Spaces [PDF]

open access: yesProceedings of the American Mathematical Society, 1995
We prove that every full symmetrically normed ideal of operators on a Hilbert space is realizable as the set of completely bounded maps between two homogeneous operator Hilbert spaces, with the c.b. norm equivalent to (but in general not equal to) the symmetric norm. We show that one can have equality of the c.b.

QNP_SHELL: A computerized tool for improving decision-making skills for nuclear power plant operators

open access: yesCogent Engineering, 2015
Decision-making in complex systems such as nuclear power plants (NPPs) is a difficult task at best. The safety and integrity of many such high-capital cost-intensive installations depend on the operator’s capability to correctly diagnose and take ...
