Incompatibility of Observables as State-Independent Bound of Uncertainty Relations [PDF]

open access: yes, 2019
For a pair of observables, they are called "incompatible", if and only if the commutator between them does not vanish, which represents one of the key features in quantum mechanics. The question is, how can we characterize the incompatibility among three

Performance measurement in small motels in Australia [PDF]

open access: yes, 2007
This research explores the measurement of performance in small motels. There are many challenges facing business performance management in small firms. Most of these challenges are due to resource shortages, lack of functional expertise and environmental

Near-Field Matching and Universal Limits on Electromagnetic Energy Transfer

open access: yesMathematics, 2023
This article introduces the concept of near-field (NF) matching as a continuum-mode generalization of port matching in circuit theory suitable for field-theoretic electromagnetic energy transfer scenarios, with a focus on spatio-frequency processes in ...

COVARIANT INTEGRAL QUANTIZATIONS AND THEIR APPLICATIONS TO QUANTUM COSMOLOGY

open access: yesActa Polytechnica, 2016
We present a general formalism for giving a measure space paired with a separable Hilbert space a quantum version based on a normalized positive operator-valued measure.

LNG Bunkering Station Deployment Problem—A Case Study of a Chinese Container Shipping Network

open access: yesMathematics, 2023
Liquefied natural gas (LNG) is a promising measure to reduce shipping emissions and alleviate air pollution problem, especially in coastal areas. Currently, the lack of a complete infrastructure system is preventing the extensive application of dual ...

Quantum-inspired cognitive agents

open access: yesFrontiers in Applied Mathematics and Statistics, 2022
The concept of intelligent agents is—roughly speaking—based on an architecture and a set of behavioral programs that primarily serve to solve problems autonomously.

Robustness of the BB84 quantum key distribution protocol against general coherent attacks [PDF]

open access: yes, 2005
It is demonstrated that for the entanglement-based version of the Bennett-Brassard (BB84) quantum key distribution protocol, Alice and Bob share provable entanglement if and only if the estimated qubit error rate is below 25% or above 75%. In view of the

Study on the Operators’ Attention of Different Areas in University Laboratories Based on Eye Movement Tracking Technology

open access: yesIEEE Access, 2020
To explore different operators’ eye movement characteristics, which can reflect their degree of attention and hazard identification ability in university laboratories, experiments were carried out with 60 junior students.

Decoupling of Deficiency Indices and Applications to Schr\"odinger-Type Operators with Possibly Strongly Singular Potentials [PDF]

open access: yes, 2016
We investigate closed, symmetric $L^2(\mathbb{R}^n)$-realizations $H$ of Schr\"odinger-type operators $(- \Delta +V)\upharpoonright_{C_0^{\infty}(\mathbb{R}^n \setminus \Sigma)}$ whose potential coefficient $V$ has a countable number of well-separated ...

Generalized reflection coefficients [PDF]

open access: yes, 2014
I consider general reflection coefficients for arbitrary one-dimensional whole line differential or difference operators of order $2$. These reflection coefficients are semicontinuous functions of the operator: their absolute value can only go down when ...
