Book Description
Many books on writing tell you how to think more creatively, how to conjure up an idea from scratch. Many, once you have an idea, show you how to express it clearly and elegantly. And many handbooks offer reliable advice on the use of commas, semicolons, and so forth. But The New Oxford Guide to Writing does all three, so that no matter where you find yourself in the writing process--from the daunting look of a blank page, to the rough draft that needs shaping, to the small but important questions of punctuation--you will find what you need in one handy, all-inclusive volume. Highlighted by numerous examples of successful prose--including marvelous, brief excerpts from Mark Twain, Joan Didion, H.L. Mencken, E.B. White, and Annie Dillard--this stimulating volume covers the entire subject step-by-step, clearly and authoritatively. It shows: ___*How to use commonplace books and journals to store ____ideas, how to brainstorm, how to explore a potential ____topic systematically ___*How to use a statement of purpose or an outline to ____give preliminary shape to your material, how to use ____drafts and revisions (and more revisions) to refine ____your ideas ___*How to open an essay clearly and interestingly, how to ____lead the reader subtly, how to use qualifications to ____express complexity without sacrificing impact ___*How to organize ideas into a coherent paragraph, how ____to vary sentence structure and length for variety and ____emphasis ___*How to select words that convey both information and ____point of view ___*And much, much more In addition, it contains a useful appendix on punctuation, ranging from commas and periods to underlining and capitalization. Whether you write for business or for pleasure, whether you are a beginner or an experienced pro, The New Oxford Guide to Writing is an essential addition to your reference library, providing abundant assistance and encouragement to write with more clarity, more color, and more force.

Book Description
Algorithmic puzzles are puzzles involving well-defined procedures for solving problems. This book will provide an enjoyable and accessible introduction to algorithmic puzzles that will develop the reader's algorithmic thinking. The first part of this book is a tutorial on algorithm design strategies and analysis techniques. Algorithm design strategies — exhaustive search, backtracking, divide-and-conquer and a few others — are general approaches to designing step-by-step instructions for solving problems. Analysis techniques are methods for investigating such procedures to answer questions about the ultimate result of the procedure or how many steps are executed before the procedure stops. The discussion is an elementary level, with puzzle examples, and requires neither programming nor mathematics beyond a secondary school level. Thus, the tutorial provides a gentle and entertaining introduction to main ideas in high-level algorithmic problem solving. The second and main part of the book contains 150 puzzles, from centuries-old classics to newcomers often asked during job interviews at computing, engineering, and financial companies. The puzzles are divided into three groups by their difficulty levels. The first fifty puzzles in the Easier Puzzles section require only middle school mathematics. The sixty puzzle of average difficulty and forty harder puzzles require just high school mathematics plus a few topics such as binary numbers and simple recurrences, which are reviewed in the tutorial. All the puzzles are provided with hints, detailed solutions, and brief comments. The comments deal with the puzzle origins and design or analysis techniques used in the solution. The book should be of interest to puzzle lovers, students and teachers of algorithm courses, and persons expecting to be given puzzles during job interviews.

Book Description
In the history of modern computation, large mechanical calculators preceded computers. A person would sit there punching keys according to a procedure and a number would eventually appear. Once calculators became fast enough, it became obvious that the critical path was the punching rather than the calculation itself. That is what made the stored program concept vital to further progress. Once the instructions were stored in the machine, the entire computation could run at the speed of the machine. This book shows how to do the same thing for DNA computing. Rather than asking a robot or a person to pour in specific strands at different times in order to cause a DNA computation to occur (by analogy to a person punching numbers and operations into a mechanical calculator), the DNA instructions are stored within the solution and guide the entire computation. We show how to store straight line programs, conditionals, loops, and a rudimentary form of subroutines. To achieve this goal, the book proposes a complete language for describing the intrinsic topology of DNA complexes and nanomachines, along with the dynamics of such a system. We then describe dynamic behavior using a set of basic transitions, which operate on a small neighborhood within a complex in a well-defined way. These transitions can be formalized as purely syntactical functions of the string representations. Building on that foundation, the book proposes a novel machine motif which constitutes an instruction stack, allowing for the clocked release of an arbitrary sequence of DNA instruction or data strands. The clock mechanism is built of special strands of DNA called ""tick"" and ""tock."" Each time a ""tick"" and ""tock"" enter a DNA solution, a strand is released from an instruction stack (by analogy to the way in which as a clock cycle in an electronic computer causes a new instruction to enter a processing unit). As long as there remain strands on the stack, the next cycle will release a new instruction strand. Regardless of the actual strand or component to be released at any particular clock step, the ""tick"" and ""tock"" fuel strands remain the same, thus shifting the burden of work away from the end user of a machine and easing operation. Pre-loaded stacks enable the concept of a stored program to be realized as a physical DNA mechanism. A conceptual example is given of such a stack operating a walker device. The stack allows for a user to operate such a clocked walker by means of simple repetition of adding two fuel types, in contrast to the previous mechanism of adding a unique fuel -- at least 12 different types of strands -- for each step of the mechanism. We demonstrate by a series of experiments conducted in Ned Seeman's lab that it is possible to ""initialize"" a clocked stored program DNA machine. We end the book with a discussion of the design features of a programming language for clocked DNA programming. There is a lot left to do.
