ABSTRACT

We report on the experimental observation of reduced light-energy transport and disorder-induced localization close to a boundary of a truncated 1D disordered photonic lattice. Our observations uncover that a higher level of disorder near the boundary is required to obtain similar localization than in the bulk.

ABSTRACT

Activation of lymphoid cells by both T and B cell mitogens was inhibited by gold sodium thiomalate (GST). The action of GST did not appear to be exerted at early stages of lymphocyte activation. Inhibition by GST was sustained throughout 4 days of culture. The inhibitory effect of GST was reduced at low serum concentrations. Sodium thiomalate and sodium chloroaurate were also able to inhibit lymphocyte activation.
