Since the discovery of kHz quasi-periodic oscillations (QPO) in neutron star binaries, the difference between peak frequencies of two modes in the upper part of the spectrum, i.e. ∆ω = ωh − ωk has been studied extensively. The idea that ∆ω is constant and (as a beat frequency) is related to the rotational frequency of the neutron star has been tested previously. The observed decrease of ∆ω when...

Effect of time dependent normal transpiration on the problem of unsteady viscous flow and heat transfer in the vicinity of an axisymmetric stagnation point of an infinite circular cylinder moving simultaneously with time-depended angular and axial velocities and with time-dependent wall temperature or wall heat flux are investigated. The impinging free stream is steady with a strain rate . A re...

This paper studies the internal wave band of temperature fluctuation spectra in the coastal zone of Pacific ocean. It is observed that on the central Mexican Pacific Shelf in the high-frequency band of temperature spectra the spectral exponent tends to ∼ω−1 at the time of spring tide and ω−2 at the time of neap tide. On the western shelf of the Japan/East Sea, in the ≪ω≪N∗ range, where N∗ is t...

INTRODUCTION Bone marrow transplantation (BMT) is a major modality for malignant and hematologic disorders. This procedure is associated with a high morbidity and mortality such as acute kidney injury (AKI). Many factors, such as therapeutic agents, irradiation, and graft versus host disease (GVHD) can cause AKI. Bone marrow transplantation conditioning therapy in Iran is based on drugs such as...

where u(x, t) = (u,u,u) represents the velocity, ω(x, t) = (ω,ω,ω) stands for the angular velocity field of rotation of particles, p is the pressure, f and f̃ represent the external force and moment, respectively. The positive parameters ν , νr , c, ca, cd are the viscous coefficients. In fact, ν is the usual Newtonian kinetic viscosity, and νr is the dynamics microrotation viscosity, and...

We study the angular correlations of various galaxy catalogs (CfA1, SSRS1, Perseus-Pisces, APM Bright Galaxies and Zwicky). We find that the angular correlation exponent is γ a = 0.1 ± 0.1 rather than γ a = 0.7 as usually found by the standard correlation function ω(θ). We identify the problem in the artificial decay of ω(θ). Moreover we find that no characteristic angular scale is present in a...

Abstract. We carry out a systematic analytic investigation of stationary and cylindrically symmetric vortex configurations for simple models representing an incompressible non-relativistic superconductor in a background, which is rigidly rotating with the angular velocity Ω∞. It is shown that although the magnetic and kinetic contributions to the energy per unit length of such a vortex are sepa...

We show that the L(w) operator norm of the composition M◦TΩ, where M is the maximal operator and TΩ is a rough homogeneous singular integral with angular part Ω ∈ L∞(Sn−1), depends quadratically on [w]A2 , and this dependence is sharp.

Discuss the scattering of a plane electromagnetic wave of angular frequency ω that is incident on a perfectly conducting sphere of radius a, which is at rest, when the wavelength obeys λ a (ka 1). Calculate the electromagnetic fields and the Poynting vector everywhere, and interpret these fields in both the near and far zones. Consider incident electromagnetic waves of both linear and circular ...

We construct solutions, for small values of G and angular frequency Ω, of special relativistic scalar gravity coupled to ideally elastic matter which have helical but no stationary or axial symmetry. They correspond to a body without any symmetries in steady rotation around one of its axes of inertia, or two bodies moving on a circle around their center of gravity. Our construction is rigorous,...
