A Model of the Galactic Centre with Magnetic Monopoles
A model of the galactic centre with magnetic monopole has been presented here. The positron can be produced continuously through magnetic monopoles to induce baryon decay (Rubakov catalytic reaction) and a lot...

X-Ray Spectra of Various Bursts from the Rapid Burster
About 20 type-I bursts and 3000 type-II bursts were observed with Tenma and Hakucho in 1983. Spectral evolutions were analyzed for both types of bursts and results are presented.

Solution in cosine series for the bending of a rectangular cantilever plate under the action of arbitrary transverse loads
In this paper the concept of a generalized clamped edge is proposed and the bending problem of a rectangular cantilever plate under arbitrary loads is resolved in cosine series by the method of superposition.

Boundary Element Analysis of Magnetoelastic Buckling of a Thin Beam-Plate Finite in Size
Moon and Pao [1] first dealed with magnetoelastic buckling of a plate, with a great discrepancy between their theoretical predictions and experimental results. Later some investigators showed that this discrep...

Subspace Variational Principles and Their Applications for Develo** the Constitutive Equations of Rods, Plates, and Shells
In the construction of the theories of rods, plates, and shells there are two kinds of methods (cf. (1) (2)): direct approach based on 1- or 2-dimensional director continuum models and approximation of 3-dimen...

Nonlinear parametric instability and millisecond solar radio spikes
A model of nonlinear parametric instability (NLPI) modulation is suggested to explain the millisecond spikes in solar decimetric radio emission. The radio emission energy will periodically transfer to two othe...

Magnetic and Mössbauer studies of Fe/Mo multilayered thin films
Fe(x)/Mo(y), multilayered thin films (MLF) with y=7.0 nm and x=0.7, 1.3, 2.6, 3.6, 13.0 nm were fabricated by radio frequency (RF) sputtering. X-ray diffraction evidences that these films have a good periodici...

On the nonlinear statistical relation of solar radio spikes
Based on a modulation model of nonlinear parametric instability, some theoretical expectation of statistical relation of solar radio spikes have been obtained. It is shown that the modulation amplitude of spik...

Positron-Cyclotron Maser for the Core Emissions from Pulsars
We use the cyclotron-maser theory to explain the core emission from the magnetosphere of pulsars. As a kind of direct and efficient maser type of emission, it can give rise to esca** radiation with extremely...

On the envelope soliton below the H + gyrofrequency in low auroral region
Two envelope soliton events below the H + gyrofrequency with localized density depletion were discovered in low auroral region (∼ 1760 km)by Freja satellite. These events were correlated i...

Current reversals in an inhomogeneous system with asymmetric unbiased fluctuations
We present a study of the transport of a Brownian particle moving in a periodic symmetric potential in the presence of asymmetric unbiased fluctuations. The particle is considered to move in a medium with peri...

Structures of rotating traditional neutron stars and hyperon stars in the relativistic \(\sigma-\omega\) model
The influence of rotation on the total masses and radii of neutron stars is calculated by Hartle’s slow-rotation formalism, while the equation of state is considered in a relativistic

One-photon and two-photon double-slit interference in spontaneous and stimulated parametric down-conversions
We theoretically discuss two-photon double-slit interference for spontaneous and stimulated parametric down-conversions and compare it with one-photon case. We show that two-photon sub-wavelength interference ...
