Ionic Size Effect on the Spin Gap Nature of SrCu2(TeO3)2Cl2
C. N. Kuo,S. C. Chen,C. S. Lue 한국물리학회 2013 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.62 No.12
By means of magnetic susceptibility measurements, we report the effects of partial substitutionof Br onto the Cl sites of SrCu2(TeO3)2Cl2. This material has been a subject of current interestdue to indications of a spin gap behavior. However, the magnetic spin couplings responsiblefor the spin gap nature remain unclear. For each composition of SrCu2(TeO3)2(Cl1−xBrx)2, thetemperature-dependent susceptibility exhibits a character of low-dimensional magnetism with abroad maximum at Tmax. The magnitude of Tmax slightly shifts to higher temperatures with increasingBr concentration. The experimental data can be well fitted to a coupled spin dimer model,yielding an increasing trend for the spin gap size from 172 to 188 K. This indicates that the substitutionof Br ions has the effect of reducing the distance between Cu(1) and Cu(2) ions, leading toa stronger antiferromagnetic spin interaction. On the other hand, the variation of the interdimercoupling is marginal, indicative of substituting Br ions having little effect on the distance changesof Cu(1)-Cu(1) and Cu(2)-Cu(2) in SrCu2(TeO3)2Cl2.

In recent years, more and more point-to-point communication systems involve simultaneous transmission of multiple sources of human perceptual data over a single communication medium. For example, in a teleoperation system or a telerobotic system, streams of video, audio, and haptic data need to be sent from a field place to a remote human operator. Each type of data demands a certain range of transmission rate. This creates conflicts among these data when the available bandwidth is limited. In this paper we study the bandwidth allocation for multiple sources of human perceptual data transmitted over a rate-limited communication channel. We aim to maximize the overall user satisfaction in the data transmission, and formulate an optimization problem for the bandwidth allocation. Using either the logarithmic or exponential form of human perceptual satisfaction function, we are able to derive closed-form solutions for the optimization problem. We show that the optimal bandwidth allocation for each type of data is piecewise linear with respect to the total available bandwidth.
Dietary Glutamine Supplementation Enhances Weaned Pigs Mitogen-Induced Lymphocyte Proliferation

Two experiments involving 92 crossbred, 21 day old weaned pigs were used to evaluate the effect of glutamine supplement in a dietary or culture medium on lymphocyte proliferation. In Exp. 1, 88 pigs were fed diets supplemented with 0, 0.5, 1.0, or 1.5% glutamine for 28 days. Lymphocytes were prepared from peripheral blood mononuclear cells (PBMC), ileal Peyer's patches (PP), the mesenteric lymph node (MLN), and the spleen in each dietary supplement group on days 7, 14, or 28 postweaning. Lymphocytes were cultured at $37^{\circ}C$ for 72 h in a RPMI-1640 medium with or without mitogen-stimulated, and pulsed with 3Hthymidine for an additional 18 h. The stimulation index of PBMC proliferation in 1.0% dietary glutamine supplement group and both of the MLN and splenocytes proliferation in 1.5% dietary glutamine supplement group was significantly (p<0.05) increased at 14 days postweaning. In Exp. 2, four weaned pigs were fed a basal diet for 14 days. The 3H-thymidine incorporation of PBMC, PP, and MLN cells, incubated with 0.125 to 0.25 mM glutamine in culture medium were markedly enhanced with Con A-stimulated, however, the splenocyte proliferation was not affected in the addition of glutamine medium. These observations suggest that dietary glutamine supplement might enhance the lymphocyte proliferation of weaned pigs.
