Introduction to algebraic geometry

Algebraic geometry, central to pure mathematics, has important applications in such fields as engineering, computer science, statistics and computational biology, which exploit the computational algorithms that the theory provides. Users get the full benefit, however, when they know something of the underlying theory, as well as basic procedures and facts. This book is a systematic introduction to the central concepts of algebraic geometry most useful for computation. Written for advanced undergraduate and graduate students in mathematics and researchers in application areas, it focuses on specific examples and restricts development of formalism to what is needed to address these examples. In particular, it introduces the notion of Gröbner bases early on and develops algorithms for almost everything covered. It is based on courses given over the past five years in a large interdisciplinary programme in computational algebraic geometry at Rice University, spanning mathematics, computer science, biomathematics and bioinformatics.

Bird Migration and Global Change

Changes in seasonal movements and population dynamics of migratory birds in response to ongoing changes resulting from global climate changes are a topic of great interest to conservation scientists and birdwatchers around the world. Because of their dependence on specific habitats and resources in different geographic regions at different phases of their annual cycle, migratory species are especially vulnerable to the impacts of climate change.?In Bird Migration and Global Change, eminent ecologist George W. Cox brings his extensive experience as a scientist and bird enthusiast to bear in evaluating the capacity of migratory birds to adapt to the challenges of a changing climate.?Cox reviews, synthesizes, and interprets recent and emerging science on the subject, beginning with a discussion of climate change and its effect on habitat, and followed by eleven chapters that examine responses of bird types across all regions of the globe. The final four chapters address the evolutionary capacity of birds, and consider how best to shape conservation strategies to protect migratory species in coming decades.?The rate of climate change is faster now than at any other moment in recent geological history. How best to manage migratory birds to deal with this challenge is a major conservation issue, and Bird Migration and Global Change is a unique and timely contribution to the literature.

THE IMMORTAL LIFE OF HENRIETTA LACKS

The book talks about Henrietta Lacks and the immortal cell line, known as HeLa, from Lacks' cervical cancer cells in 1951. Skloot became interested in Lacks after a biology professor mentioned, but did not know her much. Skloot began conducting extensive research on her and worked with the Lacks family to create the book. The book is notable for its scientific writing and treating ethical issues of race and class in medical research. Skloot said some of the information came from the diary of Deborah Lacks, daughter of Henrietta Lacks, as well as "photos and archival documents, scientific and historical research ". This is Skloot's first book.

Immunology and Evolution of Infectious Disease PDF

From HIV to influenza, the battle between infectious agents and the immune system is at the heart of disease. Knowledge of how and why parasites vary to escape recognition by the immune system is central to vaccine design, the control of epidemics, and our fundamental understanding of parasite ecology and evolution. As the first comprehensive synthesis of parasite variation at the molecular, population, and evolutionary levels, this book is essential reading for students and researchers throughout biology and biomedicine. The author uses an evolutionary perspective to meld the terms and findings of molecular biology, immunology, pathogen biology, and population dynamics. This multidisciplinary approach offers newcomers a readable introduction while giving specialists an invaluable guide to allied subjects. Every aspect of the immune response is presented in the functional context of parasite recognition and defense—an emphasis that gives structure to a tremendous amount of data and brings into sharp focus the great complexity of immunology. The problems that end each chapter set the challenge for future research, and the text includes extensive discussion of HIV, influenza, foot-and-mouth disease, and many other pathogens. This is the only book that treats in an integrated way all factors affecting variation in infectious disease. It is a superb teaching tool and a rich source of ideas for new and experienced researchers. For molecular biologists, immunologists, and evolutionary biologists, this book provides new insight into infectious agents, immunity, and the evolution of infectious disease.

Classification and risk assessment in AML PDF

In recent years, the composite molecular architecture in acute myeloid leukemia (AML) has been mapped out. We now have a clearer understanding of the key genetic determinants, the major genetic interactions, and the broad order in which these mutations occur. The next impending challenge is to discern how these recent genomic discoveries define disease biology as well as how to use molecular markers to deliver patient-tailored clinical decision support.

Clinical implications of somatic mutations in aplastic anemia and myelodysplastic syndrome in genomi

Recent technological advances in genomics have led to the discovery of new somatic mutations and have brought deeper insights into clonal diversity. This discovery has changed not only the understanding of disease mechanisms but also the diagnostics and clinical management of bone marrow failure. The clinical applications of genomics include enhancement of current prognostic schemas, prediction of sensitivity or refractoriness to treatments, and conceptualization and selective application of targeted therapies. However, beyond these traditional clinical aspects, complex hierarchical clonal architecture has been uncovered and linked to the current concepts of leukemogenesis and stem cell biology. Detection of clonal mutations, otherwise typical of myelodysplastic syndrome, in the course of aplastic anemia (AA) and paroxysmal nocturnal hemoglobinuria has led to new pathogenic concepts in these conditions and created a new link between AA and its clonal complications, such as post-AA and paroxysmal nocturnal hemoglobinuria. Distinctions among founder vs subclonal mutations, types of clonal evolution (linear or branching), and biological features of individual mutations (sweeping, persistent, or vanishing) will allow for better predictions of the biologic impact they impart in individual cases. As clonal markers, mutations can be used for monitoring clonal dynamics of the stem cell compartment during physiologic aging, disease processes, and leukemic evolution.

La fiancée de Lammermoor

La Fiancée de Lammermoor (en anglais, The Bride of Lammermoor) est un roman tragique et historique de l'auteur écossais Walter Scott. Il forme avec Une légende de Montrose la troisième série des Contes de mon hôte. Les deux livres paraissent le même jour, le 21 juin 1819, sous le pseudonyme de Jedediah Cleishbotham. Walter Scott (Sir Walter Scott, 1er baronnet) est un poète et écrivain écossais né le 15 août 1771 à Édimbourg et mort le 21 septembre 1832 à Abbotsford. Scott a été un précurseur pour deux tendances majeures qui se sont affirmées avec le temps : le roman historique, dont le succès lui a valu d'innombrables imitateurs au XIXe siècle, et la culture des Hautes Terres de l'Écosse, après le cycle d'Ossian de James Macpherson, dans ses romans écossais comme dans les usages vestimentaires, puisqu'il a rétabli l'usage du kilt et des tartans. En son honneur, la gare centrale d'Édimbourg a été nommée Waverley en 1854 et son image apparaît sur les billets émis par la banque d'Écosse. Extrait : À la fin, Caleb, d'une main tremblante, souleva les barres de fer, ouvrit la porte pesante et resta un moment immobile devant eux. Ses cheveux gris, courts et très clairs, son front chauve et ses traits sillonnés de rides mais caractéristiques, étaient éclairés par la lueur d'une lampe qu'il tenait d'une main, tandis qu'il la couvrait de l'autre pour en protéger la flamme contre le vent. Le regard craintif et tout à la fois respectueux qu'il jeta autour de lui, l'effet de la lumière sur son visage et ses cheveux blancs auraient pu faire le sujet d'un fort bon tableau ; mais nos voyageurs étaient trop impatients de se mettre à l'abri de l'orage qui commençait à obscurcir l'horizon pour s'amuser à étudier le pittoresque. -- Est-ce vous, mon cher maître, est-ce vous ? s'écria le vieux domestique. Je suis fâché, bien fâché que vous ayez attendu si longtemps à la porte de votre propre château ; mais qui eût pensé que vous reviendriez si tôt et accompagné d'un étranger. Dans cet endroit, il s'interrompit, se retourna, et se mit à parler dans le corridor, comme dans un {aparté, à quelque habitant de la tour qu'on ne voyait point, et assez bas, à ce qu'il croyait, pour ne pas être entendu des deux amis qui étaient toujours dans la cour.
