Generalizations of AM-GM-HM means inequalities

open access: yesAIMS Mathematics, 2023
In this paper, we showed some generalized refinements and reverses of arithmetic-geometric-harmonic means (AM-GM-HM) inequalities due to Sababheh [J. Math. Inequal. 12 (2018), 901–920].

A Critical Scoping Review of Pesticide Exposure Biomonitoring Studies in Overhead Cultures

open access: yesToxics, 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]

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.

Understanding Operator Influence in Automated Urban Shuttle Buses and Recommendations for Future Development

open access: yesMultimodal Technologies and Interaction, 2022
The automation of our vehicles is an all-present topic with great benefits for society, particularly in the area of public transport and pilot projects of automated shuttle buses are already underway. However, they do not show the full potential of using

Matrices related to some Fock space operators [PDF]

open access: yesOpuscula 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.

Operative hysteroscopy

open access: yesInternational 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]

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.
