E. Complete the following sentence about regulation of cell division. MPF (maturation promoting factor) is formed by a combination of \_\_\_\_\_\_\_\_ and \_\_\_\_\_\_\_\_. When MPF is formed, it phosphorylates \_\_\_\_\_\_\_\_ that degrades cyclin and when cyclin level goes down, MPF activity \_\_\_\_\_\_\_\_. When cyclin levels go up, \_\_\_\_\_\_\_\_ activity increases and cell division starts.

(3) (35pts) Consider the following planar problem of a frame, which is supported by a pinned support at the bottom and a roller support at its left edge. The horizontal beam in the frame is loaded by a linearly distributed force $Q$ which varies from 12kN/m at the left edge to 0kN/m at the right edge where it meets the vertical beam. The beam consists of metal with $\sigma_y = 200 MPa$ and $\sigma_{ut} = 400 MPa$. For the case in which the vertical beam has a constant square cross-section, determine the required width $b$ of the cross-section of the vertical beam based on the design criterion that the average stresses in the middle cross-section of the beam (i.e. at $x = 5m$) cannot lead to permanent deformation in that section of the beam. Use a safety factor of 4.

Consider the following (ad hoc) distributed lag model: $Y_t = \alpha_0 + \beta_0 X_t + \beta_1 X_{t-1} + \beta_2 X_{t-2} + ... + \beta_p X_{t-p} + \epsilon_t$, where $p$ is a fairly large number. Which of the following is not a typical problem a researcher confronts when estimating such a model by OLS: A. the degrees of freedom tend to decrease substantially if the number of lags is large. B. the various lagged values of X are likely to be severely multicollinear. C. there is no guarantee that the estimated $\beta$'s will follow the smoothly declining pattern that economic theory would typically suggest. D. heteroskedasticity.

5. Sketch a transition diagram for the push-down automaton that recognizes the context-free language specified by the following grammar below, where S is the starting variable. You do not need to label all of the states, but you do need to clearly indicate the starting and accepting states. S \rightarrow aSb | Tab T \rightarrow cdT | dcT
