The measure of a measurement [PDF]

open access: yesJournal of Mathematical Physics, 2007
We identify a fractal scale s in a family of Borel probability measures μ on the unit interval which arises independently in quantum information theory and in wavelet analysis. The scales s we find satisfy s∊R+ and s≠1, some s<1 and some s>1.

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 ...

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 ...

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,

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 ...

Bioactive Trace Metal Distributions and Biogeochemical Controls in the Southern Ocean [PDF]

open access: yes, 2012
Extensive sampling in many regions of the Southern Ocean has demonstrated that surface water concentrations of dissolved Fe are low enough to limit phytoplankton growth. In contrast, there is currently no evidence that other bioactive elements (e.g., Mn,

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.

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.

A direction-sensitive photodetector based on the two-dimensional WSe2/MoSe2 lateral heterostructure with enhanced photoresponse

open access: yesResults in Physics, 2023
Photodetectors based on anisotropic materials are attracting lots of attention. This research systematically investigates the anisotropic photoresponse of photodetectors based on the two-dimensional WSe2/MoSe2 lateral heterostructure through quantum ...
