This course treats various methods to design and analyze datastructures and algorithms for a wide range of problems. The most important new datastructure treated is the graph, and the general methods introduced are: greedy algorithms, divide and conquer, dynamic programming and network flow algorithms. These general methods are explained by a number of concrete examples, such as simple scheduling algorithms, Dijkstra, Ford-Fulkerson, minimum spanning tree, closest-pair-of-points, knapsack, and Bellman-Ford. Throughout this course there is significant attention to proving the correctness of the discussed algorithms. All material for this course is in English. The recorded lectures, however, are in Dutch.

The Native Korean numbers are used when you say your age, tell the time or count something in Korean.And this system is only needed to tell the numbers from 1 to 99. Bigger numbers (like 100 for instance) existed in the past in native Korean numbers but they are no longer used. So all you have to remember is the numbers between 1~99. Therefore, it would be much easier for you to memorize these numbers compared to the Sino Korean Numbers

Are you a current or future caregiver, or, a nurse or other healthcare professional who wants to learn more about Alzheimer’s disease? Here are the key content areas that will be addressed over 5 modules: Over 5 million Americans and an estimated 24 million people worldwide are living with Alzheimer’s disease (AD). Given the exponential aging of the population, these numbers are expected to increase dramatically over the next few decades; Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills and, eventually, the ability to carry out the simplest tasks. It is the most common cause of dementia among older adults and has both genetic and environmental factors in its development; AD is characterized by a variety of cognitive symptoms, including short-term memory loss, problems with problem-solving, judgment and recognition. There are also changes in mood and neuropsychiatric symptoms such as depression, hallucinations and paranoia. Behavioral expressions, include irritability, agitation, resistance to care, and wandering. In the later stages, the person is dependent in all activities of daily living and requires total care; There is no known cause, effective treatment or cure, but there are currently two classes of medications approved to enhance cognitive function, as well as, lifestyle-based preventive strategies thought to possibly reduce risk; There are evidence-based therapeutic approaches and communication strategies to enhance interactions and optimally, prevent behavioral expressions; The key principles of care for the hospitalized person with Alzheimer’s disease are examined, including the importance of therapeutic communication strategies to prevent behavioral expressions and other complications such as delirium and falls; Lastly, the essential role of the dementia caregiver is discussed, including potential consequences, stresses and gratifications, as well as the resources available.

American Contract Law for a Global Age by Franklin G. Snyder and Mark Edwin Burge of Texas A&M University School of Law is a casebook designed primarily for the first-year Contracts course as it is taught in American law schools, but is configured so as to be usable either as a primary text or a supplement in any upper-level U.S. or foreign class that seeks to introduce American contract law to students. As an eLangdell text, it offers maximum flexibility for students to read either in hard copy or electronic format on most electronic devices. Why “American” Contract Law? Nearly all American contract law texts focus on U.S. law. This volume simply makes that focus explicit. Modern American lawyers face an increasingly global world, and the book makes it clear that American law is not the only important commercial law regime in the world. But much of the value that the cosmopolitan and transnational American-trained lawyer brings to the table is an understanding of the contract law of the United States. To this end, the venerable English cases that exemplify common law doctrine are here presented not in their hoary 19th century settings. but in the 21st century forms that students can intuitively grasp.

This text is a comprehensive introduction to the vital subject of American government and politics. Governments decide who gets what, when, how (See Harold D. Lasswell, Politics: Who Gets What, When, How, [New York: McGraw-Hill, 1936]); they make policies and pass laws that are binding on all a society's members; they decide about taxation and spending, benefits and costs, even life and death. Governments possess power—the ability to gain compliance and to get people under their jurisdiction to obey them—and they may exercise their power by using the police and military to enforce their decisions. However, power need not involve the exercise of force or compulsion; people often obey because they think it is in their interest to do so, they have no reason to disobey, or they fear punishment. Above all, people obey their government because it has authority; its power is seen by people as rightfully held, as legitimate. People can grant their government legitimacy because they have been socialized to do so; because there are processes, such as elections, that enable them to choose and change their rulers; and because they believe that their governing institutions operate justly. Politics is the process by which leaders are selected and policy decisions are made and executed. It involves people and groups, both inside and outside of government, engaged in deliberation and debate, disagreement and conflict, cooperation and consensus, and power struggles. In covering American government and politics, our text introduces the intricacies of the Constitution, the complexities of federalism, the meanings of civil liberties, and the conflicts over civil rights;explains how people are socialized to politics, acquire and express opinions, and participate in political life; describes interest groups, political parties, and elections—the intermediaries that link people to government and politics; details the branches of government and how they operate; and shows how policies are made and affect people's lives.

forall x is an introduction to sentential logic and first-order predicate logic with identity, logical systems that significantly influenced twentieth-century analytic philosophy. After working through the material in this book, a student should be able to understand most quantified expressions that arise in their philosophical reading. This books treats symbolization, formal semantics, and proof theory for each language. The discussion of formal semantics is more direct than in many introductory texts. Although forall x does not contain proofs of soundness and completeness, it lays the groundwork for understanding why these are things that need to be proven. Throughout the book, I have tried to highlight the choices involved in developing sentential and predicate logic. Students should realize that these two are not the only possible formal languages. In translating to a formal language, we simplify and profit in clarity. The simplification comes at a cost, and different formal languages are suited to translating different parts of natural language. The book is designed to provide a semester's worth of material for an introductory college course. It would be possible to use the book only for sentential logic, by skipping chapters 4-5 and parts of chapter 6.

The goal of this text is to present philosophy to newcomers as a living discipline with historical roots. While a few early chapters are historically organized, the goal in the historical chapters is to trace a developmental progression of thought that introduces basic philosophical methods and frames issues that remain relevant today. Later chapters are topically organized. These include philosophy of science and philosophy of mind, areas where philosophy has shown dramatic recent progress. This text concludes with four chapters on ethics, broadly construed. Traditional theories of right action is covered in a third of these. Students are first invited first to think about what is good for themselves and their relationships in a chapter of love and happiness. Next a few meta-ethical issues are considered; namely, whether they are moral truths and if so what makes them so. The end of the ethics sequence addresses social justice, what it is for one's community to be good. Our sphere of concern expands progressively through these chapters. Our inquiry recapitulates the course of development into moral maturity. Over the course of the text, the author has tried to outline the continuity of thought that leads from the historical roots of philosophy to a few of the diverse areas of inquiry that continue to make significant contributions to our understanding of ourselves and the world we live in.

We are constantly bombarded by information, and finding a way to filter that information in an objective way is crucial to surviving this onslaught with your sanity intact. This is what statistics, and logic we use in it, enables us to do. Through the lens of statistics, we learn to find the signal hidden in the noise when it is there and to know when an apparent trend or pattern is really just randomness. The study of statistics involves math and relies upon calculations of numbers. But it also relies heavily on how the numbers are chosen and how the statistics are interpreted.

The aim of this class is to introduce the exciting and often under appreciated discoveries in RNA biology by exploring the diversity of RNAs—encompassing classical molecules such as ribosomal RNAs (rRNAs), transfer RNAs (tRNAs) and messenger RNAs (mRNAs) as well as newer species, such as microRNAs (miRNAs), long-noncoding RNAs (lncRNAs), and circular RNAs (circRNAs). For each new class of RNA, we will evaluate the evidence for its existence as well as for its proposed function. Students will develop both a deep understanding of the field of RNA biology and the ability to critically assess new papers in this fast-paced field. This course is one of many Advanced Undergraduate Seminars offered by the Biology Department at MIT. These seminars are tailored for students with an interest in using primary research literature to discuss and learn about current biological research in a highly interactive setting. Many instructors of the Advanced Undergraduate Seminars are postdoctoral scientists with a strong interest in teaching.

As currently taught in the United States, introductory courses in analytical chemistry emphasize quantitative (and sometimes qualitative) methods of analysis along with a heavy dose of equilibrium chemistry. Analytical chemistry, however, is much more than a collection of analytical methods and an understanding of equilibrium chemistry; it is an approach to solving chemical problems. Although equilibrium chemistry and analytical methods are important, their coverage should not come at the expense of other equally important topics. The introductory course in analytical chemistry is the ideal place in the undergraduate chemistry curriculum for exploring topics such as experimental design, sampling, calibration strategies, standardization, optimization, statistics, and the validation of experimental results. Analytical methods come and go, but best practices for designing and validating analytical methods are universal. Because chemistry is an experimental science it is essential that all chemistry students understand the importance of making good measurements. My goal in preparing this textbook is to find a more appropriate balance between theory and practice, between “classical” and “modern” analytical methods, between analyzing samples and collecting samples and preparing them for analysis, and between analytical methods and data analysis. There is more material here than anyone can cover in one semester; it is my hope that the diversity of topics will meet the needs of different instructors, while, perhaps, suggesting some new topics to cover.

This video was recorded at European Conference on Machine Learning and Principles and Practice of Knowledge Discovery in Databases (ECML PKDD), Athens 2011. Comparing frequency counts over texts or corpora is an important task in many applications and scientific disciplines. Given a text corpus, we want to test a hypothesis, such as "word X is frequent", "word X has become more frequent over time", or "word X is more frequent in male than in female speech". For this purpose we need a null model of word frequencies. The commonly used bag-of-words model, which corresponds to a Bernoulli process with fixed parameter, does not account for any structure present in natural languages. Using this model for word frequencies results in large numbers of words being reported as unexpectedly frequent. We address how to take into account the inherent occurrence patterns of words in significance testing of word frequencies. Based on studies of words in two large corpora, we propose two methods for modeling word frequencies that both take into account the occurrence patterns of words and go beyond the bag-of-words assumption. The first method models word frequencies based on the spatial distribution of individual words in the language. The second method is based on bootstrapping and takes into account only word frequency at the text level. The proposed methods are compared to the current gold standard in a series of experiments on both corpora. We find that words obey different spatial patterns in the language, ranging from bursty to non-bursty/uniform, independent of their frequency, showing that the traditional approach leads to many false positives.
