We introduce the concept of the envelope dyadic Green’s function (EDGF) and present a formalism to study the propagation of electromagnetic fields with slowly varying amplitude (EMFSVA) in dispersive anisotropic media with two dyadic constitutive parameters: the dielectric permittivity and the magnetic...
Spectral Lines: For the first time in a half century, the news about agriculture in sub-Saharan Africa is actually goodZachary, G.P.IEEE SPECTRUM
Universal approximation theorems can be regarded as a single category. Prior to the research of RC, universal representation theorems by Boyd and Chua showed that any time-invariant continuous nonlinear operator can be approximated either by a Volterra series or alternatively by a linear dynamical syst...
Learn about real-time spectrum analyzers for sound and vibration measurements also known as vibration analyzers. See how they work and how they are used.
Tomographic methodsThese methods create a series of 2D slices to generate a 3D volume and provide non-destructive, high-resolution data of external and internal structures or even the movement of small molecules through a root system in the case of plants. X-ray computed tomography (CT), magnet...
SMTH outperforms other models in the green-red region, notably above 600 nm, where most existing ocean-color sensors have a limited number of spectral bands. Despite this variability, all models, showcase satisfactory performance in the 443–560 nm region. Significantly, both SMTH and LNR ...
The proteomic ruler approach is readily applicable to any deep eukaryotic proteome dataset—even in retrospective analysis—and we demonstrate its usefulness with a series of mouse organ proteomes.Previous article in issue Next article in issue Mass spectrometry (MS)1 is now capable of analyzing the...
In a linear system, the frequency response can be obtained by sweeping sinusoidal inputs over a range of frequencies. This series of sinusoidal signals at different frequencies can then be used to compute the frequency response. While the ALICE Desktop Bode Plotter does include a sweep generator ...
gene expression similarity between cells and combine it with the first set via a weighted mean (Methods). The resulting matrix of directed transition probabilities is independent of any low-dimensional embedding and reflects transcriptional similarity as well as directional information given by RNA ...
preprocessed fMRI response time-series from three example voxels for an example subject are plotted for the full duration of the story stimulus (x-axis: fMRI signal magnitude;y-axis: scan duration in TRs; red: early auditory cortex; orange: auditory association cortex; purple: temporoparietal ju...
