Relationship between the total IgE levels and specific IgE antibodies

In this study, nine allergens were selected; i.e. 1289 cases of d1, 1277 cases of e1, 1547 cases of f1, 1063 cases of t17 and others, for investigating the relationship between the total IgE level and RAST score. The results showed that the total IgE level was high in high d1 score, and 29 cases of low IgE level were observed in high f1 score groups. On the other hand, the comparison of the CAP system and the total IgE level showed. The result shows that one case of low total IgE value was found in highest d1 score group.     

Replica symmetry breaking transition of the weakly anisotropic Heisenberg spin glass in magnetic fields

The spin and the chirality orderings of the three-dimensional Heisenberg spin glass with the weak random anisotropy are studied under applied magnetic fields by equilibrium Monte Carlo simulations. A replica symmetry breaking transition occurs in the chiral sector accompanied by the simultaneous spin-glass order. The ordering behavior differs significantly from that of the Ising spin glass, despite the similarity in the global symmetry. Our observation is consistent with the spin-chirality decoupling-recoupling scenario of a spin-glass transition.     

The effective surjectivity of mod l Galois representations of 1- and 2-dimensional abelian varieties with trivial endomorphism ring

Mod l Galois representations of 1- and 2-dimensional abelian varieties with trivial endomorphism ring are surjective for sufficiently large prime l as Serre proved. But he did not give an effective lower bound of l ₀ such that they are surjective for l > l ₀. We supply an effective evaluation of l ₀ by an elementary proof of the surjectivity. The proof uses the Masser-Wüstholz theorem and Kleidman and Liebecks classification of the maximal subgroups of GL ₂ F _l ) and GSp ₄ (F _l ).     

QCD analysis of twist-4 contributions to the g i structure functions

We analyze the twist-4 contributions to Bjorken and Ellis-Jaffe sum rules for spin-dependent structure function g ₁(x, Q ²). We investigate the anomalous dimensions of the twist-4 operators which determine the logarithmic correction to the 1/Q ² behavior of the twist-4 contribution by evaluating off-shell Green’s functions in both flavor non-singlet and singlet case. It is shown that the operators which are proportional to the equation of motion play an important role to extract the anomalous dimensions of physical operators. The calculations to solve the operator mixing of higher-twist operators are given in detail     

Impurity-concentration dependence of internal magnetic field acting on platinum in ferromagnetic iron metal

It was found by perturbed angular correlation that the internal magnetic fields acting on platinum in iron were kept in a definite value for uniform alloy samples with impurity concentration ranging from 2 at% to 0.1 at%. Theg-factor of 355.7 keV level of¹⁹⁶Pt was revised tog=0.335±0.018 using the refined ωτ.     

Optical absorption of small metallic particles

In an extremely small metallic particle in which electron energies take discrete values, a light is absorbed by the surface plasmon which is not decayed by the surface scattering. The usually used relation between polarizability of a particle and electrical susceptibility does not hold.     

Nuclear g-factor of the 172+ isomeric state in 63Cu

The nuclear g-factor of the 4498 keV $\text{17}\text{2}$⁺ isomeric state in ⁶³Cu was measured with the in-bearn perturbed angular distribution method, through the ⁶²Ni(α, p2nγ)⁶³Cu reaction, to be g_exp = 0.184 ± 0.012. This value is in good agreement with a semiempirical g-factor for the three-quasiparticle configuration [π2p_{$\text{3}\text{2}$}(v1f_{$\text{5}\text{2}$}, 1g_{$\text{9}\text{2}$})₇]_{$\text{17}\text{2}$⁺} calculated using the experimental single-particle g-factors of neighbouring nuclei. At the same time the internal magnetic field at the Cu nuclei in Ni metal was obtained to be B_int = ?46.6 ± 1.3 kG.     

Photo-induced magnetophonon resonance in n-InSb at 4.2°K

Spin-flip and two-phonon as well as normal magnetophonon resonance are observed in CO₂-laser-irradiated photoconductivity in n-InSb at 4.2°K. The effects are attributed to the resonant cooling of photo-excited electrons due to optical phonon emission.
