THz-to-optical conversion in wireless communications using an ultra-broadband plasmonic modulator

Future wireless communication networks will need to handle data rates of tens or even hundreds of Gbit s⁻¹ per link, requiring carrier frequencies in the unallocated THz spectrum^1,2. In this context, seamless int...

In/Si(111): Self-Assembled One and Two-Dimensional Electron Gases

We present angle-resolved photoemission measurements for ultrathin In films on Si(111). Depending on the coverage, this system self-organizes into a metallic monolayer with either 4×1 or v7×v3 symmetry relativ...

Bone marrow cells produce a novel TSHβ splice variant that is upregulated in the thyroid following systemic virus infection

Although cells of the immune system can produce thyroid-stimulating hormone (TSH), the significance of that remains unclear. Using 5′ rapid amplification of cDNA ends (RACE), we show that mouse bone marrow (BM...
