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

A Critical Scoping Review of Pesticide Exposure Biomonitoring Studies in Overhead Cultures
Toxics, 2022 The exposure of operators, workers, residents and bystanders to pesticides is of high potential concern. Yet, reports on pesticide residues in the environment and near treated fields often spark debates if such findings might indicate a health risk ...

Operational Phase Operators and Hermitian Phase Operators [PDF]
Progress 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.

International Journal of Gynecology & Obstetrics, 1993 AbstractOBJECTIVE: Analysis of the obtained results after operative hysteroscopy for several intrauterine abnormalities. METHOD: Thirty women with uterine problems (7 polyps, 16 endometrial, 5 endocervical adhesions and 2 lost IUDs) were submitted to operative hysteroscopy under general anesthesia by using fine rigid auxiliary instruments at Lito ...

Operator Ideals and Operator Spaces [PDF]
Proceedings 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.

Cogent 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 ...

Matrices related to some Fock space operators [PDF]
Opuscula Mathematica, 2011 Matrices of operators with respect to frames are sometimes more natural and easier to compute than the ones related to bases. The present work investigates such operators on the Segal-Bargmann space, known also as the Fock space.
