Measuring unrecorded measurement [PDF]

open access: yesEPL (Europhysics Letters), 2016
Projective (Von Neumann) Measurement of an operator (i.e. a dynamical variable) selected from a prescribed set of operators is termed unrecorded measurement (URM) when both the selected operator and the measurement outcome are unknown, i.e. "lost". Within classical physics a URM is completely inconsequential: the state is unaffected by measurement ...

High Speed and Precision Underwater Biological Detection Based on the Improved YOLOV4-Tiny Algorithm

open access: yesJournal of Marine Science and Engineering, 2022
Realizing high-precision real-time underwater detection has been a pressing issue for intelligent underwater robots in recent years. Poor quality of underwater datasets leads to low accuracy of detection models. To handle this problem, an improved YOLOV4-

Wedged Fiber Optic Surface Plasmon Resonance Sensor for High-Sensitivity Refractive Index and Temperature Measurements

open access: yesSensors, 2022
Here, we experimentally demonstrate a wedged fiber optic surface plasmon resonance (SPR) sensor enabling high-sensitivity temperature detection. The sensing probe has a geometry with two asymmetrical bevels, with one inclined surface coated with an ...

The Difficulty of Measuring the Measurable [PDF]

open access: yesRespiratory Care, 2014
When we were students of medicine at Zurich University, we were obliged to do a 1-month internship called Hafelipraktikum. For many of us, this job constituted the very first opportunity to become familiar with our future profession, namely with real patients in a hospital.

Enhancement of transverse magneto-optical Kerr effect based on surface plasmon and its application in sensing

open access: yesResults in Physics, 2023
In recent years, the combination of magnetic and plasma properties of nanostructures has become a hot research topic. However, most such studies focuse on prism-based sandwich structures, which not only hinders device miniaturization but also has weak ...

The electron–phonon scattering and charge transport of the two-dimensional (2D) polar h-BX(X = P, As, Sb) monolayers

open access: yesNew Journal of Physics, 2023
In this paper, the electron–phonon scattering and phonon-limited transport properties of the two-dimensional polar h-BX(X = P, As, Sb) have been studied through first-principles calculations in combination with Boltzmann transport theory.

Underwater Image Restoration via DCP and Yin–Yang Pair Optimization

open access: yesJournal of Marine Science and Engineering, 2022
Underwater image restoration is a challenging problem because light is attenuated by absorption and scattering in water, which can degrade the underwater image.
