TFP image in diluted methane flame. Filament spacing is about 10 mm. Thin-filament pyrometry (TFP) is an optical method used to measure temperatures. It involves the placement of a thin filament in a hot gas stream. Radiative emissions from the filament can be correlated with filament temperature.
Digital reconstruction or tracing of neuron morphology is a fundamental task in computational neuroscience. [1] [2] [3] It is also critical for mapping neuronal circuits based on advanced microscope images, usually based on light microscopy (e.g. laser scanning microscopy, bright field imaging) or electron microscopy or other methods.
The time at which a filament reaches the Batchelor scale is therefore called its mixing time. The resolution of the advection–diffusion equation shows that after the mixing time of a filament, the decrease of the concentration fluctuation due to diffusion is exponential, resulting in fast homogenization with the surrounding fluid.
The disappearing-filament pyrometer is an optical pyrometer, in which the temperature of a glowing incandescent object is measured by comparing it to the light of a heated filament. [ 1 ] [ 2 ] [ 3 ] Invented independently in 1901 by Ludwig Holborn and Ferdinand Kurlbaum in Germany and Everett Fleet Morse in the United States, [ 1 ] it was the ...
Filament propagation has been observed in several photo-polymerizable systems, including organo-siloxane, [11] acrylics, [12] epoxy and copolymers with epoxies, [13] and polymer blends. [ 14 ] [ 15 ] The locations of filament formation and propagation may be controlled by modulating the spatial profile of the input light field.
Fluorescent tracer, a substance such as 2-NBDG containing a fluorophore that is used for tracking purposes; Histochemical tracer, a substance used for tracing purposes in histochemistry, the study of the composition of cells and tissues; Isotopic tracer, a substance with an isotope that has been enriched to a greater level than that found in nature
In structural biology, as well as in virtually all sciences that produce three-dimensional data, the Fourier shell correlation (FSC) measures the normalised cross-correlation coefficient between two 3-dimensional volumes over corresponding shells in Fourier space (i.e., as a function of spatial frequency [1]).
The sliding filament theory explains the mechanism of muscle contraction based on muscle proteins that slide past each other to generate movement. [1] According to the sliding filament theory, the myosin ( thick filaments ) of muscle fibers slide past the actin ( thin filaments ) during muscle contraction, while the two groups of filaments ...
