Problem 9: Matlab We start with an analog signal x(t) given below x(t) = cos(2? 150 t) +0.3 sin(2?1900t) +0.7 cos(2? 3300 t) x(t) is then sampled at a sampling frequency of 4000 Hz for 3 seconds to generate the sequence {x(n)} (a) Take the DFT of x(n) in Matlab and plot both the magnitude and the phase response of the DFT (b) using a truncated sinc sequence design the best approximate filter to an ideal brick wall los pass filter with a cut off frequency of $w_c = \frac{\pi}{2}$. Verify your filter by plotting its frequency response using matlab (c) pass the sequence x(n) through the filter to generate the sequence y(n), take the DFT of y(n) and plot both its magnitude and phase response.

PROBLEMS 7.1 Derive the lowest-order non-vanishing S-matrix element (7.19) and hence the corresponding Feynman amplitude for Bhabha scattering, i.e. the process e+(p?, r?) + e-(p?, r?) ? e+(p?, s?) + e-(p?, s?). 7.2 Show that the Feynman amplitude for the photon self-energy diagram in Fig. 7.9 is given by M = -e²/(2?)? ? d?p Tr [?_r(k) S_F(p+k) ?_s(k) S_F(p)] where k and ?_r(k) are the momentum and polarization vectors of the photon.

Items 16 and 17 are based on the following information: You were engaged as an independent auditor of Thomas Corporation. In the course of your examination of the accounts on December 31, 2004, the end of the accounting period, you determined that certain prepaid and accrued items were not recorded in prior years and in the current year as follows: Accrued expenses Prepaid expenses Prepaid revenues Revenues receivable 2002 2003 2004 4,500 7,500 6,500 5,000 12,000 8,000 1,200 3,000 2,750 2,500 Retained earnings at the end of 2002 amounted to P445,000 while net income for 2003 was reported at P126,000. The income summary account for 2004 shows a credit balance of P150,000 before any audit adjustments. You have verified that no dividends were declared in the two year period. 16. Compute for the corrected Retained earnings balance as of December 31, 2002. a. P 444,300 b. P 450,000 c. P 578,500 d. P 445,000 17. The corrected net income for the years ended December 31, 2003 and 2004 are: 2003 2004 a. P126,000 P150,000 b. P134,200 P143,750 c. P146,700 P168,000 d. P122,200 P155,750

Q1. Please outline FOUR methods that would allow you to identify an enhancer element for a putative oncogene you discovered using a prostate cancer cell line model. Include at least one method that is genomic-scale. Briefly describe how the method works. Q2. You just started a rotation in a virology lab and have been assigned to analyze a human blood sample, which had been infected by a new virus. In addition to other phenotypes your lab has observed, you discovered that RNA molecules and particularly polyA-containing RNAs are retained in the nucleus at 10 times the level compared to a control blood sample. You suspected that a viral protein might be interfering with the nuclear dynamics of the cells and after some investigation, you determined that the virus is overproducing a protein called JUST MAKING UP A NAME. Please generate AT LEAST TWO HYPOTHESES of the function of JUSTMAKINGUPANAME pertaining to the said phenotype. Then outline the experimental design (approach) for testing such a hypothesis and the expected results if your hypothesis were true.
