Phase Transitions (Primers in Complex Systems #3)
by Ricard SoléPhase transitions--changes between different states of organization in a complex system--have long helped to explain physics concepts, such as why water freezes into a solid or boils to become a gas. How might phase transitions shed light on important problems in biological and ecological complex systems? Exploring the origins and implications of sudden changes in nature and society, Phase Transitions examines different dynamical behaviors in a broad range of complex systems. Using a compelling set of examples, from gene networks and ant colonies to human language and the degradation of diverse ecosystems, the book illustrates the power of simple models to reveal how phase transitions occur. Introductory chapters provide the critical concepts and the simplest mathematical techniques required to study phase transitions. In a series of example-driven chapters, Ricard Solé shows how such concepts and techniques can be applied to the analysis and prediction of complex system behavior, including the origins of life, viral replication, epidemics, language evolution, and the emergence and breakdown of societies. Written at an undergraduate mathematical level, this book provides the essential theoretical tools and foundations required to develop basic models to explain collective phase transitions for a wide variety of ecosystems.

Phase Transitions in Two-Dimensional Complex Plasmas
by Christina A. KnapekThe two experimental studies reported in this thesis contribute important new knowledge about phase transitions in two-dimensional complex plasmas: in one case a determination of the coupling parameter (ratio of mean potential to mean kinetic energy of the particles in an ensemble), and in the other a detailed characterization of the non-equilibrium recrystallization of a two-dimensional system. The latter results are used to establish the connection between structural order parameters and the kinetic energy, which in turn gives novel insights into the underlying physical processes determining the two-dimensional phase transition.

The Phaselock Code: Through Time, Death and Reality -- The Metaphysical Adventures of Man
by Roger HartONE MAN'S REMARKABLE SEARCH FOR THE ULTIMATE TRUTHS OF OUR WORLD. For Professor Roger Hart, life truly began after he almost lost his -- in a horrific fall off the slopes of Mount Everest that he miraculously survived. This near-death experience sparked a desire in him to devote his studies to the very nature of human consciousness, in order to unlock the code of reality that binds our world. On an adventure of discovery that would take him around the world, Hart would experience life-altering transcendental events in Tibet, Morocco, and Tierra del Fuego -- opening the door to a true understanding of the nature of man. In this groundbreaking volume, he explores the participation of consciousness in the creation of reality, challenging the traditional scientific view of time, space, and objectivity -- and describing in detail his own metaphysical journey, which has involved synchronicity, precognition, and telekinesis. It is an exploration of the very things that make us human -- and a quest that touches upon the meaning of life itself.

Pheno-phospholipids and Lipo-phenolics: Novel Structured Antioxidants
by Mohamed Fawzy RamadanNatural phenolics are powerful bioactive compounds, but their use as antioxidant agents in lipid-based foodstuffs and cosmetics is limited due to their hydrophilic traits. A promising technique to overcome low solubility of phenolics is to increase their hydrophobicity by grafting with lipophilic moiety to form lipid-enriched phenolics (lipo-phenolics). Another way to enhance the amphiphilic traits of phenolics is by lipophilization with phospholipids in a suitable solvent to form phenolics-enriched phospholipids (pheno-phospholipids). Both functionalized phenolics (phenolipids) exhibit high bioavailability and antioxidative potential. Functional phenolics-enriched phospholipids (pheno-phospholipids) play an important role in enhancing the functional properties of both phenolic compounds and phospholipids in food for their use in nutrition and health. Phenolipids have also found applications on an industrial scale, likely due to low costs, the availability of starting material and safety. Recent advances in the field of lipophilization allow accessing molecules with high potency and targeted action covering a wide spectrum of bioactivities. Owing to their cost and availability, phenolipids find applications in niche sectors such as cosmetics and pharmaceutics as well as in the novel food. This book reports on the chemistry, preparation, and functionality of lipid-enriched phenolics (lipo-phenolics), broadening their applications in food, pharmaceuticals and cosmetics. The strategies of the lipophilization of phenolics, the effect of modification on the biological properties and potential applications of the resulting lipo-phenolics are reviewed. The text also discusses the preparation, physicochemical characteristics and functional properties of phenolipids and phytosomes, including the latest developments and their current industrial status.

Phenolic Resins: A Century of Progress
by Louis PilatoWith global capacity in excess of 5 million tons annually, phenolic resins are one of the leading thermosetting resins that are used in many diverse industries such as wood adhesives, fiberglass/mineral wool binder, molded materials for autos/electronic/electrical industries, brakes, abrasives, foam, coatings/adhesives, laminates, composites, metal castings/refractories, and rubber industry. These phenolic resin business areas are critical to the national economy and general welfare of emerging and developed nations. Although phenolic resins are barely noticed in these applications, it is difficult to imagine their absence since they are vital and not easily replaced by other polymeric materials due to favorable cost/performance characteristics of phenolic resins. In this new book these application areas are summarized and updated by global phenolic experts that are engaged daily in these activities. Further new technology and application areas of global technical activity are presented and include nanotechnology, updated phenolic resin chemistry, carbon fiber and long glass fiber reinforced molding materials, new analyses/testing, carbon foam, carbon/carbon brakes for autos, photo resists, new fiber reinforced systems, renewable raw materials, and recycling. It is anticipated that the new book will feature a global perspective of phenolic resins through the participation of international (North America, Europe and Asia) phenolic experts that was lacking in all previous books related to phenolic resins.

Phenological Research
by Irene L. Hudson Marie R. KeatleyAs climate change continues to dominate the international environmental agenda, phenology - the study of the timing of recurring biological events - has received increasing research attention, leading to an emerging consensus that phenology can be viewed as an 'early warning system' for climate change impact. A multidisciplinary science involving many branches of ecology, geography and remote sensing, phenology to date has lacked a coherent methodological text. This new synthesis, including contributions from many of the world's leading phenologists, therefore fills a critical gap in the current biological literature. Providing critiques of current methods, as well as detailing novel and emerging methodologies, the book, with its extensive suite of references, provides readers with an understanding of both the theoretical basis and the potential applications required to adopt and adapt new analytical and design methods. An invaluable source book for researchers and students in ecology and climate change science, the book also provides a useful reference for practitioners in a range of sectors, including human health, fisheries, forestry, agriculture and natural resource management.
Phenological Synchrony and Bird Migration: Changing Climate and Seasonal Resources in North America (Studies in Avian Biology)
by Eric M. Wood Jherime L. KellermannBird migration is a well-researched phenological event. However, few studies in North America have investigated the effects of climate change and extreme weather on the relationships of migratory avian species and their seasonal resources. This is a critical gap in knowledge that limits our ability to prioritize management and conservation applicat
Phenology (The MIT Press Essential Knowledge series)
by Theresa M. CrimminsOn the timing of seasonal activity in plants and animals, the impact of climate change, and what each of us, as everyday phenologists, can do to help.Phenology is all about timing—when trees leaf out, flowers bloom, birds migrate, animals bear young and hibernate—and it is everywhere around us. This handy companionable volume shows how we are all phenologists in our own way, and how the everyday science can help us make sense of the changing seasons and our changing world. Explaining how the phenomenon of phenology is threaded through our daily lives, Theresa Crimmins points to events that occur on an annual basis in plants’ and animals’ lives in response to fluctuations in daylength, temperatures, and rainfall patterns. She also covers less visible seasonal events, such as when roots typically begin to grow or when mushrooms release their spores. On a more urgent note, Phenology describes how this seasonal activity is being affected by rapidly changing climate conditions—and why this matters. Consequently, the book invites readers to participate in documenting the timing of seasonal life cycle events—for the practice’s real benefits to mental health, but also for the good of the environment, as the data gathered can be directly helpful in supporting climate change action.
Phenology: An Integrative Environmental Science
by Mark D. SchwartzPhenology refers to recurring plant and animal life cycle stages, such as leafing and flowering, maturation of agricultural plants, emergence of insects, and migration of birds. It is also the study of these recurring events, especially their timing and relationships with weather and climate. Phenological phenomena all give a ready measure of the environment as viewed by the associated organism, and are thus ideal indicators of the impact of local and global changes in weather and climate on the earth's biosphere. Assessing our changing world is a complex task that requires close cooperation from experts in biology, climatology, ecology, geography, oceanography, remote sensing, and other areas. Like its predecessor, this second edition of Phenology is a synthesis of current phenological knowledge, designed as a primer on the field for global change and general scientists, students, and interested members of the public. With updated and new contributions from over fifty phenological experts, covering data collection, current research, methods, and applications, it demonstrates the accomplishments, progress over the last decade, and future potential of phenology as an integrative environmental science.

Phenology of Ecosystem Processes
by Asko NoormetsTerrestrial carbon balance is uncertain at the regional and global scale. A significant source of variability in mid-latitude ecosystems is related to the timing and duration of phenological phases. Spring phenology, in particular, has disproportionate effects on the annual carbon balance. However, the traditional phenological indices that are based on leaf-out and flowering times of select indicator species are not universally amenable for predicting the temporal dynamics of ecosystem carbon and water exchange. Phenology of Ecosystem Processes evaluates current applications of traditional phenology in carbon and H2O cycle research, as well as the potential to identify phenological signals in ecosystem processes themselves. The book summarizes recent progress in the understanding of the seasonal dynamics of ecosystem carbon and H2O fluxes, the novel use of various methods (stable isotopes, time-series, forward and inverse modeling), and the implications for remote sensing and global carbon cycle modeling. Each chapter includes a literature review, in order to present the state-of-the-science in the field and enhance the book's usability as an educational aid, as well as a case study to exemplify the use and applicability of various methods. Chapters that apply a specific methodology summarize the successes and challenges of particular methods for quantifying the seasonal changes in ecosystem carbon, water and energy fluxes. The book will benefit global change researchers, modelers, and advanced students.
Phenomenological Approaches to Physics (Synthese Library #429)
by Harald A. Wiltsche Philipp BerghoferThis book offers fresh perspective on the role of phenomenology in the philosophy of physics which opens new avenues for discussion among physicists, "standard" philosophers of physics and philosophers with phenomenological leanings.Much has been written on the interrelations between philosophy and physics in the late 19th and early 20th century, and on the emergence of philosophy of science as an autonomous philosophical sub-discipline. This book is about the under-explored role of phenomenology in the development and the philosophical interpretation of 20th century physics. Part 1 examines questions about the origins and value of phenomenological approaches to physics. Does the work of classical phenomenologists such as Husserl, Merleau-Ponty or Heidegger contain elements of systematic value to both the practice and our philosophical understanding of physics? How did classical phenomenology influence “standard” philosophy of science in the Anglo-American and other traditions? Part 2 probes questions on the role of phenomenology in the philosophies of physics and science:- Can phenomenology help to solve “Wigner’s puzzle”, the problem of the "unreasonable effectiveness" of mathematics in describing, explaining and predicting empirical phenomena? - Does phenomenology allow better understanding of the principle of gauge invariance at the core of the standard model of contemporary particle physics? - Does the phenomenological notion of “Lifeworld” stand in opposition to the “scientific metaphysics” movement, or is there potential for dialogue? Part 3 examines the measurement problem. Is the solution outlined by Fritz London and Edmond Bauer merely a re-statement of von Neumann’s view, or should it be regarded as a distinctively phenomenological take on the measurement problem? Is phenomenology a serious contender in continuing discussions of foundational questions of quantum mechanics? Can other interpretational frameworks such as quantum Bayesianism benefit from implementing phenomenological notions such as constitution or horizonal intentionality?
A Phenomenological Inquiry into Science Teachers’ Case Method Learning (SpringerBriefs in Education)
by Sye Foong YeeThis book illustrates a practical application of the Case Method as a teaching technique in teacher education, and examines how learning takes place in a teacher professional development activity. It also describes teachers’ lived experience of the activity based on Clark Moustakas' 1994 guidelines for organizing and presenting a phenomenological study.
A Phenomenological Revision of E. E. Harris's Dialectical Holism
by James SchofieldThe purpose of this work is to critically assess Errol E. Harris’s process philosophy in the face of contemporary research in the special sciences. Harris devoted his life to grappling with the big questions concerning the relationships between nature, mind, and knowledge. His 70-plus year career was distinguished, his texts on the history of philosophy, philosophy of science, political philosophy, philosophy of religion, and consciousness were widely published, and yet his metaphysics has until now remained excluded from mainstream discussions. This book’s contention is that Harris’s work reveals as yet unnoticed connections between theories in numerous scientific disciplines ranging from psychology to cosmology and that an examination of certain theories within these disciplines may serve to strengthen his original arguments. This work maintains that the resulting metaphysics frames a transdisciplinary paradigm shift and provides a viable solution to the hard problem of consciousness.
Phenomenology and Mathematics
by Mirja HartimoDuring Edmund Husserl's lifetime, modern logic and mathematics rapidly developed toward their current outlook and Husserl's writings can be fruitfully compared and contrasted with both 19th century figures (Boole, Schröder, Weierstrass) as well as the 20th century characters (Heyting, Zermelo, Gödel). Besides the more historical studies, the internal ones on Husserl alone and the external ones attempting to clarify his role in the more general context of the developing mathematics and logic, Husserl's phenomenology offers also a systematically rich but little researched area of investigation. This volume aims to establish the starting point for the development, evaluation and appraisal of the phenomenology of mathematics. It gathers the contributions of the main scholars of this emerging field into one publication for the first time. Combining both historical and systematic studies from various angles, the volume charts answers to the question "What kind of philosophy of mathematics is phenomenology?"
Phenomenology and QBism: New Approaches to Quantum Mechanics (Routledge Studies in the Philosophy of Mathematics and Physics)
by Philipp Berghofer Harald A. WiltscheThis volume brings together philosophers and physicists to explore the parallels between Quantum Bayesianism, or QBism, and the phenomenological tradition. It is the first book exclusively devoted to phenomenology and quantum mechanics. By emphasizing the role of the subject’s experiences and expectations, and by explicitly rejecting the idea that the notion of physical reality could ever be reduced to a purely third-personal perspective, QBism exhibits several interesting parallels with phenomenology. The central message of QBism is that quantum probabilities must be interpreted as the experiencing agent’s personal Bayesian degrees of belief—degrees of belief for the consequences of their actions on a quantum system. The chapters in this volume elaborate whether and specify how phenomenology could serve as the philosophical foundation of QBism. This objective is pursued from the perspective of QBists engaging with phenomenology as well as the perspective of phenomenologists engaging with QBism. These approaches enable us to realize a better understanding of quantum mechanics and the world we live in, achieve a better understanding of QBsim, and introduce the phenomenological foundations of quantum mechanics. Phenomenology and QBism is an essential resource for researchers and graduate students working in philosophy of physics, philosophy of science, quantum mechanics, and phenomenology.
