It is easier for someone who knows Japanese to learn more Japanese words than it is for someone who knows little to no Japanese (novice). Mechanistically, this is because to the novice, Japanese words hold zero-to-little meaning. Japanese language is not interesting to the novice. the experienced speaker has the relevant stronger neural connections that have been established long ago when (s)he was learning the language. Japanese has greater relevance for the experienced speaker. the experienced speaker has stronger neural pathways for languages in general.

1. Landauer-Büttiker formalism: consider a four terminal device with current flowing from terminal 1 to terminal 3, but no current in terminals 2 and 4. Find the ratio of the voltage drop between terminals 1 and 3 to the voltage drop between terminals 2 and 4, if $T_{12} = T_{24} = 0.60$, $T_{14} = T_{23} = 0$, $T_{13} = 0.45$ and $T_{34} = 0.30$. Assume $T_{pq} = T_{qp}$ for all terminals $p$, $q$, where $T_{pq}$ is the total transmission between terminal $q$ and terminal $p$.

5. A discrete random variable X has the following probability mass function (pmf): p0 = 0.2, p2 = 0.05, p3.5 = 0.3, p5 = 0.25, p6 = 0.2 (a) State the support of X, Sx. (b) Determine the cdf of X, Fx. (c) Use the cdf, Fx, to calculate P(2 < X < 5). (Use 1.interval) (d) Use the pmf, p(x), to calculate P(2 < X < 5) and P(2 < X â‰¤ 5). How are they different? (e) Use the cdf, Fx, to calculate P(2.5 < X â‰¤ 5) and P(2.5 < X < 5). How are they different? (f) Calculate the expectation, E(X). Find out E(3X - 5X^2 + 7). What is E(5)? (g) What is the expression of Var(X) in this problem if you use the definition of Var(X) = E{X - E(X)}? Alternatively, use Var(X) = E(X^2) - {E(X)} to calculate Var(X). What is Var(-3X + 5)?
