Air kerma to H-P(3) conversion coefficients for IEC 61267 RQR X-RAY radiation qualities: application to dose monitoring of the lens of the eye in medical diagnostics [PDF]

open access: yes, 2016
Recent studies highlight the fact that the new eye lens dose limit can be exceeded in interventional radiology procedures and that eye lens monitoring could be required for these workers.

The Bunsen gas solubility coefficient of ethylene as a function of temperature and salinity and its importance for nitrogen fixation assays [PDF]

open access: yes, 2004
The acetylene reduction assay is a common method for assessing nitrogen fixation in a variety of marine and freshwater systems. The method measures ethylene, the product of the conversion of the gas acetylene to its reduced form by nitrogenase. Knowledge

Supermodes of grating-coupled multimode waveguides and application to mode conversion between copropagating modes mediated by backward Bragg scattering [PDF]

open access: yes, 1999
An analysis of multimode waveguides where several modes are coupled via quasiperiodic perturbations is presented. The supermodes (or eigenmodes) of the structure are derived and orthonormality considerations are discussed. In addition, a new type of mode

Nested (inverse) binomial sums and new iterated integrals for massive Feynman diagrams [PDF]

open access: yes, 2014
Nested sums containing binomial coefficients occur in the computation of massive operator matrix elements. Their associated iterated integrals lead to alphabets including radicals, for which we determined a suitable basis.

WECIA Graph: Visualization of Classification Performance Dependency on Grayscale Conversion Setting

open access: yesMendel, 2018
Grayscale conversion is a popular operation performed within image pre-processing of many computer vision systems, including systems aimed at generic object categorization. The grayscale conversion is a lossy operation.

Evaluation of a method for converting Stratospheric Aerosol and Gas Experiment (SAGE) extinction coefficients to backscatter coefficients for intercomparison with lidar observations [PDF]

open access: yesAtmospheric Measurement Techniques, 2020
Aerosol backscatter coefficients were calculated using multiwavelength aerosol extinction products from the SAGE II and III/ISS instruments (SAGE: Stratospheric Aerosol and Gas Experiment).

Completeness and complementarity for μ → eγ, μ → e e ¯ e $$ e\overline{e}e $$ and μA → eA

open access: yesJournal of High Energy Physics, 2021
Lepton Flavour Violation (LFV) is New Physics that must occur, but is stringently constrained by experiments searching for μ ↔ e flavour change, such as μ → eγ, μ → e e ¯ e $$ e\overline{e}e $$ or μ → e conversion.
