Flow cytometric phytoplankton concentration and optical properties across instruments and laboratories

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Flow cytometry measures the optical properties of individual cells and has become essential for enumerating and characterizing marine phytoplankton. Yet systematic comparison of measurements across instruments remains limited, hampering data comparison across laboratories and long‐term time series.

Bessel's Functions [PDF]

open access: yesNature, 1899
I ONCE stated that a good style of writing English is not a strong point amongst British mathematicians, and the justice of this remark is exemplified by Prof. Hill's letter on this subject (NATURE, July 8), since it contains the phrases Meissel's tables, Smith's tables, Aldis' tables, Isherwood's tables, which are correct; and Bessel functions ...

Three‐Dimensional Optical Characterization of Magnetostrictive Deformation in Magnomechanical Systems

open access: yesLaser &Photonics Reviews, EarlyView.
An optical approach is proposed for real‐time and high‐precision detection of the magnetostrictive deformation of an yttrium‐iron‐garnet sphere in three dimensions, based on the deformation induced spatial high‐order modes of the scattered field, postselection, and balanced homodyne detection.

The Bessel-Struve intertwining operator on ℂ and mean-periodic functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
We give a description of all transmutation operators from the Bessel-Struve operator to the second-derivative operator. Next we define and characterize the mean-periodic functions on the space ℋ of entire functions and we characterize the continuous ...

Diffraction‐Free Natural Optical Skyrmions and Their Subwavelength Confinement Around Vortices

open access: yesLaser &Photonics Reviews, EarlyView.
ABSTRACT Diffraction causes waves to spread out as they propagate freely. The tighter the lateral confinement, the faster the spreading. Past research on how to suppress diffraction has been based on wave engineering and has led so far to idealized waves that, in real settings, eventually diffract.

REGARDING SOME FUNDAMENTAL ASPECTS OF DESIGN AND DEVELOPMENT OF BESSEL ULTRASONIC CONCENTRATORS USED IN NONCONVENTIONAL MACHINING

open access: yesNonconventional Technologies Review, 2023
In the category of nonconventional machining, the use of concentrated energy from ultrasonic mechanical oscillations has long been a practical solution for efficient technological utilization. This work comprehensively develops and addresses an algorithm

Extreme Optical Field Confinement and Enhancement in a Plasmonic Picopatch Within a Nanoparticle‐on‐Mirror Resonator

open access: yesLaser &Photonics Reviews, EarlyView.
A picopatch in a plasmonic nanocavity confines the electromagnetic energy to tiny effective volumes, close to 1nm3, leading to extreme electric field enhancements. Furthermore, a clear signature of strong coupling between the picopatch modes and other modes of the structure is obtained, which strongly modifies the far‐field response. ABSTRACT Plasmonic

ON WEIGHTED GENERALIZED FUNCTIONS ASSOCIATED WITH QUADRATIC FORMS

open access: yesПроблемы анализа, 2016
In this article we consider certain types of weighted generalized functions associated with nondegenerate quadratic forms. Such functions and their derivatives are used for constructing fundamental solutions of iterated ultra-hyperbolic equations with ...
