Book Description
This thesis focuses on an unresolved problem in particle and nuclear physics: the relation between two important non-perturbative phenomena in quantum chromodynamics (QCD) – quark confinement and chiral symmetry breaking. The author develops a new analysis method in the lattice QCD, and derives a number of analytical formulae to express the order parameters for quark confinement, such as the Polyakov loop, its fluctuations, and the Wilson loop in terms of the Dirac eigenmodes closely related to chiral symmetry breaking. Based on the analytical formulae, the author analytically as well as numerically shows that at finite temperatures there is no direct one-to-one correspondence between them. The thesis describes this extraordinary achievement using the first-principle analysis, and proposes a possible new phase in which quarks are confined and chiral symmetry is restored.

Book Description
'Arvid Ågren has undertaken the most meticulously thorough reading of the relevant literature that I have ever encountered, deploying an intelligent understanding to pull it into a coherent story. As if that wasn't enough, he gets it right.' (Richard Dawkins) To many evolutionary biologists, the central challenge of their discipline is to explain adaptation, the appearance of design in the living world. With the theory of evolution by natural selection, Charles Darwin elegantly showed how a purely mechanistic process can achieve this striking feature of nature. Since then, the way many biologists have thought about evolution and natural selection is as a theory about individual organisms. Over a century later, a subtle but radical shift in perspective emerged with the gene's-eye view of evolution in which natural selection was conceptualized as a struggle between genes for replication and transmission to the next generation. This viewpoint culminated with the publication of The Selfish Gene by Richard Dawkins (Oxford University Press, 1976) and is now commonly referred to as selfish gene thinking. The gene's-eye view has subsequently played a central role in evolutionary biology, although it continues to attract controversy. The central aim of this accessible book is to show how the gene's-eye view differs from the traditional organismal account of evolution, trace its historical origins, clarify typical misunderstandings and, by using examples from contemporary experimental work, show why so many evolutionary biologists still consider it an indispensable heuristic. The book concludes by discussing how selfish gene thinking fits into ongoing debates in evolutionary biology, and what they tell us about the future of the gene's-eye view of evolution. The Gene's-Eye View of Evolution is suitable for graduate-level students taking courses in evolutionary biology, behavioural ecology, and evolutionary genetics, as well as professional researchers in these fields. It will also appeal to a broader, interdisciplinary audience from the social sciences and humanities including philosophers and historians of science.

Book Description
This is a high level introduction to abstract algebra which is aimed at readers whose interests lie in mathematics and in the information and physical sciences. In addition to introducing the main concepts of modern algebra, the book contains numerous applications, which are intended to illustrate the concepts and to convince the reader of the utility and relevance of algebra today. In particular applications to Polya coloring theory, latin squares, Steiner systems and error correcting codes are described. Another feature of the book is that group theory and ring theory are carried further than is often done at this level. There is ample material here for a two semester course in abstract algebra. The importance of proof is stressed and rigorous proofs of almost all results are given. But care has been taken to lead the reader through the proofs by gentle stages. There are nearly 400 problems, of varying degrees of difficulty, to test the reader's skill and progress. The book should be suitable for students in the third or fourth year of study at a North American university or in the second or third year at a university in Europe, and should ease the transition to (post)graduate studies.

Book Description
This book is the first authoritative survey of the historical developments of Persian grammar, from the first attested work some 200 years ago to the present day. It examines the development of Persian linguistic thought in five different periods, and analyses the underlying assumptions of the grammars belonging to each period in light of contemporary ideas on the nature of grammar and new frameworks for grammatical analysis. This historical survey shows the profound influence of Arabic and Western linguistic thinking on the development of Persian grammar, as well as a dramatic shift of perspective from a traditional grammatical analysis to new and divergent procedures adopted by more recent schools of linguistics. The end result of this transition has culminated in less reliance on foreign influence and the emergence of more self-motivated, independent researchers in the uncharted territory of Persian grammar and its sub-components. The two comprehensive Persian and English glossaries at the end of the book will enable readers to better understand the grammatical concepts covered here.
