Please explain steps as best as you can. Thank you. Non-uniform Conductivity 0.0/2.0 points (graded) A cylindrical glass rod is heated with a torch until it conducts enough current to cause a light bulb to glow. The rod has a length L, a cross sectional area A, and its ends, plated with material of very high conductivity, are connected to the rest of the circuit including a voltage supply. When red hot, the rod's conductivity varies with position x measured from the center of the rod as sigma (x)=sigma _(0)(L^(2))/(x^(2)). (Part a) Consider a small slice of the rod of thickness dx located a distance x from the center of the rod as indicated in the figure. What is dR, the resistance of the small slice of rod?

Mr. Jay is a 32-year-old male electrician who works for a naval shipbuilding company. He is obese, weighing 295 lbs, and he is 5’11 inches. He reports having lost 30 pounds in the last 4 months and is tired all the time. He states he wakes up at night with wet clothing that he has to change at least once a night but he has no fevers. He states he has a history of asthma but he is controlled with inhalers. He has some swollen lymph nodes in his neck and in his axilla. He was referred to the oncologist after a large mass was revealed on his chest x-ray, and the biopsy came back with a diagnosis of Hodgkin’s disease. The oncologist ordered a CT scan of the neck, chest, abdomen, and pelvis, bone marrow aspirate and biopsy, blood work including CBC with differential and LDH. He also orders a pulmonary function test.

No disease is found in his abdomen or pelvis. His labs are shown above. Even with his asthma, he has normal lung function. His bone marrow shows no involvement. Hematologic Malignancies Question: What stage is his disease? Does he have “B” symptoms? What is his prognostic score? What is considered standard treatment for his disease? What are some potential side effects when he is treated with the standard treatment?

Problem 4 (Required, 25 marks) We consider a mean-variance portfolio problem with 4 risky assets. You are given that • The expected returns of these 4 risky assets are $\bar{r}_1 = 0.05$, $\bar{r}_2 = 0.1$, $\bar{r}_3 = 0.3$ and $\bar{r}_4 = 0.5$ respectively. • The variances of the asset returns are $\sigma_1^2 = 0.05$, $\sigma_2^2 = 0.1$ and $\sigma_3^2 = 0.25$ and $\sigma_4^2 = 0.5$ respectively. • The returns of these risky assets are mutually uncorrelated, i.e. $\sigma_{ij} = 0$ for all $i \neq j$. (a) The investor is seeking for minimum variance portfolio with expected return at least 10%. Find this portfolio. (b) Is it possible to find a portfolio with $\mu_p \ge 0.08$, $\sigma_p^2 \le 0.03$? Explain your answer.
