	1. On effect of regular S=1 dilution of S=1/2 antiferromagnetic Heisenberg chains by a quantum Monte Carlo simulation

	Abstract:The effect of S1=1 regularly dilution in S2=1/2 isotropic antiferromagnetic chain is investigated by a quantum Monte Carlo simulation. Our numerical results show that two kinds of ground-state phases alternate with a variation of the S1=1 concentration. When the effective spin in one unit cell is half-integer the ground state is ferrimagnetic with gapless energy spectrum and the magnetism decreases with decreasing of spin S1 concentration,P=1/K. While the effective spin is integer, a non-magnetic ground state with a gapped spectrum is emerged, and the gap decays gradually in a tendency fitted as {1.25*(P)^0.5}.

	2. Transmission Line Realization of Subwavelength Resonator Formed by a Pair of Conventional and LHM Slabs

	Abstract:In this paper, the authors present the transmission line (TL) realization of one-dimensional subwavelength resonator formed by a pair of conventional right-handed material (RHM) and left-handed material (LHM). In such a resonator, a novel resonant mode with the resonant frequency depending on the length ratio of the RH/LH TL sections occurs as a consequence of the full phase compensation due to the backward wave in the LH TL section. The theoretical circuit-model analyses are supported by simulation and experimental evidence on resonators with different RH/LH length ratios.

	3. Partial Synchronization in Complex Networks
	Bin Ao,Zhigang Zheng
	Physics 29 November 2005
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:Partial synchronization(PaS) in regular networks with a few non-local links is explored. Different Pas patterns out of the symmetry breaking are observed for different ways of non-local couplings. The criterion for the emergence of PaS is studied. The emergence of Pas is related to the loss of degeneration in Lyapunov exponents spectrum. Theoretic and numerical analysis show that the non-local coupling is the key of the emergency of PaS and it can change the character of the network dramatically.

	4. Novel Spacetime Concept and Dimension Curling up Mechanism in Neon Shell

	Physics 02 November 2005
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:uclidean geometry does not characterize dynamic electronic orbitals satisfactorily for even a single electron in a hydrogen atom is a formidable mathematical task with Schrodinger’s equation. Here the author puts forward a new spacetime concept that regards space and time as two orthogonal, symmetric and complementary quantities. They are inherent physical quantities that cannot be divorced from physical objects themselves. In two-dimensional helium shell, space and time are instantiated by two interactive 1s electrons; in four-dimensional neon shell, space and time dimensions blend into four types of curvilinear vectors represented by 2s, 2px, 2py, and 2pz electronic orbitals. The description of electronic orbitals constitutes an explanation of canonical spacetime properties such as harmonic oscillation, electromagnetism, and wave propagation. Through differential and integral operations, the author formulates a precise wavefunction for every electron in an inert neon atom where spac

	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:Evolution of spiral in light-sensitive media described with the two variable Oregonator model is investigated. The intensity of external illumination is modulated by a weak chaotic signal, which is introduced into the whole system, the additional Bromide production is influenced and the dynamics thus changed. The results are confirmed within our numerical simulation and it may give useful information in pattern formation and suppression of spiral.

	6. Chaotic signal-induced dynamics of Degenerate Optical Parametric Oscillator
	Ma Jun
	Physics 26 September 2005
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:The degenerate optical parametric oscillator (DOPO) is investigated. We introduced a normal Lorenz chaotic signal to adjust the amplitude and period of the input field in order to influence the dynamics of the time-dependent system. Our numerical simulation results based on the phase figures and Lyapunov spectrum confirm that the characters of the DOPO are determined by the amplitude of the input field, and the system could be controlled to reach n-periodical (n=1, 2, 3, 4, 5, etc.) orbit and stable state subjected to a modified scheme based on the self-adaptive stratagem.

	7. Lorentz, Edwards transformations and the principle of permutation invariance

	Physics 29 August 2005
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:The Lorentz transformation is derived without the postulate of the universal limiting speed, and the general Edwards transformation is obtained by using the principle of permutation invariance (covariance). It is shown that the existences of the one-way universal limiting speed (in the Lorentz transformation) and the constancy of the two-way average speed of light (in the Edwards transformation) are the necessary consequences of the principle of permutation invariance that is consistent with the postulate of relativity. The connection between the Edward transformation and the general coordinate transformation is discussed, and based on this, we find that the physical meaning of the Edward parameter, which indicates the anisotropy of the speed of light, is a gravitomagnetic potential of the spacetime.

	Abstract:In the research of the nonlinear time series prediction, we apply the least squares support vector machine (LS-SVM) to use. In order to improve the precision LS-SVM has been discussed in the following aspects. First, the parameterγand multi-step prediction capabilities of the LS-SVM network are investigated. Then we employ clustering method in the model to prune the number of the support values. The learning rate and the capabilities of filtering noise for LS-SVM are all greatly improved.
