It is usually assumed that tunneling current is fairly independent of temperature. By performing an atomistic transport simulation, we show, to the contrary, that the subthreshold tunneling current in a graphene nanoribbon (GNR) band-to-band tunneling transistor (TFET) should show significant and nonlinear temperature dependence. Furthermore, the nature of this non-linearity changes as a functi...

How do grammars assess the well-formedness of words with multiple phonotactic violations? Certain models predict that as strength restrictions decrease, forms violate should be less acceptable than expected, in a pattern we term super-linear cumulativity. We test this prediction using series Artificial Grammar Learning experiments, which vary number exceptions to patterns artificial languages. ...

Rare earth permanent magnet models are commonly used in the design of undulators and wigglers. Normally the operating point of the magnet in the B vs. H diagram corresponds to a linear reversible characteristic. The region of linearity is strongly dependent on the temperature. The operation of part of the magnet blocks in the region of non-linearity is responsible for the so-called irreversible...
