Concisely describe the steps of the Discounted Cash Flow (DCF) method used to calculate the value of a firm or project. Include description of requirements for sub-calculations, if any. 

You work in a research lab. You are studying a bacteria that when exposed to a toxic small molecule “A”, the growth is inhibited for some time (30 – 60 min), and then the bacteria gets adapted to it (responds to the presence of the toxin) and grow again. This may be an example of gene regulation based on the exposure to the toxic small molecule “A”. Propose in some details a mechanism of action for this response to “A”.

Design and implement an algorithm for the following programming contest problem using pseudocode. Analyze the algorithm in terms of its runtime and space complexity to demonstrate whether it can handle the input size. Number of Islands Implement a function numIslands function that returns an integer value (number of islands) for a given 2-dimensional integer array. [10pts] The numIslands has the following three parameters; grid: 2-dimensional integer array r: number of rows of the grid c: number of columns of the grid Explain the run-time and run-space complexity of the algorithm that you used for the implementation. [6pts] Description Given a 2d grid map of ‘1’s (land) and ‘0’s (water), count the number of islands. An island is surrounded by water and is formed by connecting adjacent lands horizontally or vertically. You may assume all four edges of the grid are all surrounded by water. The input to this program is as follows. The first line contains the number of rows and number of columns. Then, then actual grid configuration follows. Sample Input grid: [ [ 1 1 1 1 0 ] [ 1 1 0 1 0 ] [ 0 0 0 0 1 ] [ 0 0 0 1 1 ] ]r: 4c: 5 Constraints number of rows

A 20-year-old swimmer comes to the athletic trainer after diving into a pool and striking the side of his head on the water surface. He reports immediate sharp ear pain followed by decreased hearing and mild tinnitus. He denies vertigo or facial weakness. Otoscopic examination reveals a small perforation in the tympanic membrane with minimal bleeding. What is the MOST appropriate diagnosis and initial management?
