The Zeldovich Number: A Universal Dimensionless Measure for the Electromagnetic Field
Physics, 2023 In this paper we extend the Zeldovich formula, which was originally derived for the free electromagnetic field and was interpreted as the number of photons. We show that our extended formula gives a universal dimensionless measure of the overall strength

Comparison of Commonly Applied Outcome Inventories as Measures of General Internalizing Pathology in Psychological Therapies. [PDF]
Clin Psychol PsychotherABSTRACT Measuring general factors to capture severity of psychopathology broadly can be useful for assessing treatment outcomes of psychological therapies. Namely, general factors are suitable for broadband measurement, which has become increasingly important due to efforts to standardize outcome measurement.

Design and performance of a toroidal radiofrequency volume coil with intrinsic electromagnetic interference rejection for low-field portable Halbach-based MRI systems. [PDF]
Magn Reson MedAbstract Purpose One of the intrinsic limitations of low‐field MRI is low signal‐to‐noise ratio, which can be further reduced by electromagnetic interference (EMI) due to the lack of a Faraday shielded room. To address this issue, we propose a novel radiofrequency (RF) coil design that is inherently less sensitive to EMI while maintaining high receive ...

On the Number Density of Sunyaev-Zeldovich Clusters of Galaxies [PDF]
The Astrophysical Journal, 2000 If the mean properties of clusters of galaxies are well described by the entropy-driven model, the distortion induced by the cluster population on the blackbody spectrum of the Cosmic Microwave Background radiation is proportional to the total amount of intracluster gas while temperature anisotropies are dominated by the contribution of clusters of ...

Premixed Combustion in Boundary Layers for Moderate Values of the Zeldovich Numbers [PDF]
Combustion Science and Technology, 1986 The classical problem of the ignition and flame generation of combustible premixed gases by a hot flat pJate is analyzed by asymptotic techniques for moderate values of the Zeldovich numbers. For temperatures of the plate smaller than the adiabatic flame temperature it was found that the corrections to the zeroth-order solution (Zeldovich approximation)

Measuring the Mach Number of the Universe via the Sunyaev-Zeldovich Effect [PDF]
The Astrophysical Journal, 2004 We introduce a new statistic to measure more accurately the cosmic sound speed of clusters of galaxies at different redshifts. This statistic is evaluated by cross-correlating cosmic microwave background (CMB) fluctuations caused by the Sunyaev-Zel'dovich effect from observed clusters of galaxies with their redshifts.

On the calculation of a model of a three-dimensional turbulent diffusion plume
Современные инновации, системы и технологии, 2022 In this paper a three-dimensional model of diffusion combustion is presented in the case of the outflow of a combustible gas mixture from a rectangular nozzle and propagating in a heated (with a passing) air flow.

An analytical study of the effects of vaporization of twodimensional laminar droplets on a triple flame [PDF]
Journal of the Serbian Chemical Society, 2011 The structure of triple flame propagation in combustion systems, containing uniformly distributed volatile fuel droplet was analyzed. The analysis was established for a one-step irreversible reaction with an asymptotic limit, where the value of the ...
