TL;DR: In this paper, a simple approximate method to analyze dilute Ising systems is described, which takes into account the fluctuations of the effective field and is based on a probability distribution of random variables which correctly accounts for all the single site kinematic relations.

TL;DR: In this paper, the authors used the stabilisation method to calculate resonance positions and widths in e-H scattering below the N = 2 hydrogen threshold, and applied it to calculate doubly excited S-wave resonances in He.

TL;DR: In this paper, the KdV equation and the Virasoro algebra were discussed in a self-contained way and their symmetries were discussed for the first time in the context of Lie algebras.

TL;DR: Theoretical results for doubly-excited states of an ion reveal the supermultiplete struc-tures of such an ion, and its tri-atomic molecular characters in analogy to an XYXmolecule as discussed by the authors.

TL;DR: In this paper, a new explanation to the magnetic force between two conductors due to their respective currents is proposed based upon the strict usage of Coulomb's original force law, which is shown that this purely electrostatic law is capable of explaining also the magnetic forces between currents.

TL;DR: In this article, Huang et al. examined the time dependence of the solar neutrino fluxes measured by the Homestake 37C1 experiment and showed that a prominent feature in the homestake data is the statistically significant peak found at a frequency of approximately 0.1 y^(-1).

TL;DR: In this paper, Chen et al. presented a survey of the state-of-the-art results of the Synchrotron Radiation Research Center (SRC) in Hsinchu, Taiwan.

TL;DR: In this article, the pion electromagnetic form factor is recalculated based on the perturbative QCD formalism that includes the Sudakov resummation, which is consistent with experimental data, and insensitive to the variation of relevant parameters.

TL;DR: In this article, a nonlinear model of chemical reaction with supercritical Hopf bifurcation was studied stochastically by taking white noise into consideration, and it was found that both additive and multiplicative noises tend to suppress periodicity, and that only the additive noises could induce transition from a limit cycle to a fixed point.

TL;DR: In this paper, Raman spectral results indicate the possible existence of two low temperature phase transitions at 110 K and 60 K, respectively, for Triglycine Sulfate (TGS) crystals.

TL;DR: In this article, it was shown that the relic gravitons can resonantly convert into photons at the same frequencies as the primordial magnetic field, which can help to determine the power law index directly, which will distinguish different inflationary models.

TL;DR: In this article, B-splines are employed to solve the Kohn-Sham equations of the local density functional theory for atoms from H to Ca in a variational self-consistent field procedure.

TL;DR: In this article, the relationship between X-ray reflection phases and dynamical diffraction effects is briefly reviewed and a coherent dynamical interaction in a-beam and 3-beam diffraction is discussed.

TL;DR: In this article, the authors derived a new approximation of the reflectivity formula from the Fresnel formulas, and derived a series of approximate expressions for the damping rate of SPW, the resonant angle, the optimum air gap thickness of the system, and the halfwidth of resonance.

TL;DR: In this article, low-energy electron diffraction (LEED) and Auger electron spectroscopy (AES) were used to study the initial growth of a cobalt ultrathin film on a Pt(ll1) surface.

TL;DR: In this paper, the statistical potential equation for statistical potential O(x, Z, z) for atomic ions of nuclear clarge Ze and Z - z electrons has been integrated in high accuracy by means of computers.

TL;DR: In this article, the surface enhanced Raman scattering from crystal violet molecules adsorbed on Ag thin films was studied employing the attenuated total reflection configuration, and the authors attributed the observed variation of the intensity to the redistribution of the crystal violet molecule adaption on the films.

TL;DR: In this article, the magnetization and magnetic susceptibility of an electron and many ideal electrons on a ring and a more realistic hollow disk for the AharonovBohm experiment were investigated.

TL;DR: In this article, the often-studied quantum kicked rotor is examined with a modification of boundary conditions to allow for irrational momentum eigenvalues, which leads to a new eigenvalue equation.

TL;DR: The emergence of localized zero modes is responsible for the breakup of the KAM trajectories as mentioned in this paper, and these localized modes break the translational symmetry of the kam trajectories, and transform these continuous KAM tori into cantori.

TL;DR: In this article, the major and minor elemental contents of ancient bronzes and potsherds were obtained from the external-beam PIXE and vacuum-beam pixE with 3 MeV protons.

TL;DR: In this article, the correlation functions of R sites on the boundary of a planar lattice are derived for the (Nα, Nβ) model of Domany and Riedel for n = 2,3.

TL;DR: In this paper, the emission or absorption of R identical bosons from an energetic or a massive particle, in which the bosons and the source particle are allowed to be offshell, is considered.
