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 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.

CdS/SiI2: A promising two-dimensional materials for photocatalytic water splitting

open access: yesResults in Physics, 2022
Hydrogen production using photocatalyst for water splitting is considered to be one of the most promising methods to solve the energy challenge. The feasibility of CdS/SiI2 heterostructure as a photocatalyst is systematically investigated in geometrical,

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.

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 ...

Max-stable random sup-measures with comonotonic tail dependence [PDF]

open access: yes, 2016
Several objects in the Extremes literature are special instances of max-stable random sup-measures. This perspective opens connections to the theory of random sets and the theory of risk measures and makes it possible to extend corresponding notions and ...

The effect of free school fruit on academic performance: a nationwide quasi-experiment

open access: yesScientific Reports, 2023
In past research, higher intake of fruit has been associated with better academic achievement. In Norway, the government required lower secondary schools to provide fruit to their pupils from 2007 to 2014.
