Internal Dynamic Temperature Measurement of Alkali Metal Vapor Cell by Kalman Filter

open access: yesPhotonics, 2023
Measuring the internal dynamic temperature of alkali metal vapor cells is crucial for enhancing the performance of numerous atomic devices. However, conventional methods of measuring the internal dynamic temperature of the cell are prone to errors.

On the measure of Voronoi cells

open access: yesJournal of Applied Probability, 2017
Abstract We study the measure of a typical cell in a Voronoi tessellation defined by n independent random points X1, . . ., Xn drawn from an absolutely continuous probability measure μ with density f in ℝd. We prove that the asymptotic distribution of the measure – with respect to dμ = f(x)dx – of the cell containing X1 given X1 = x is independent of x

Measuring the Mechanical Properties of Plant Cell Walls

open access: yesPlants, 2015
The size, shape and stability of a plant depend on the flexibility and integrity of its cell walls, which, at the same time, need to allow cell expansion for growth, while maintaining mechanical stability.

A Promising Method for the Determination of Cell Viability: The Membrane Potential Cell Viability Assay

open access: yes, 2022
Determining the viability of cells is fraught with many uncertainties. It is often difficult to determine whether a cell is still alive, approaching the point of no return, or dead. Today, there are many methods for determining cell viability.

A measurement technique for cell adhesiveness [PDF]

open access: yesBlood, 1975
Abstract Determination of the percentage of cells in clumps on a stained smear of human peripheral blood porvided a useful, accurate technique for measuring cell adhesiveness. Smears of human peripheral blood drawn with EDTA were prepared on a blood slide centrifuge, stained, and examined under a light microscope.

Measuring fast gene dynamics in single cells with time-lapse luminescence microscopy. [PDF]

open access: yes, 2014
Time-lapse fluorescence microscopy is an important tool for measuring in vivo gene dynamics in single cells. However, fluorescent proteins are limited by slow chromophore maturation times and the cellular autofluorescence or phototoxicity that arises ...
