This book was released on 2020 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astrophysical evidence suggests that roughly 26% of the energy density of the universe is composed of non-baryonic dark matter. Although the presence of dark matter has been confirmed, its precise particle nature remains unknown. A strong candidate for what makes up the majority of dark matter is a class of particles referred to as Weakly Interacting Massive Particles (WIMPs). The Large Underground Xenon (LUX) experiment and the LUX-ZEPPLIN (LZ) experiment are dual-phase xenon Time Projection Chambers (TPCs) designed to detect the direct scattering of one of these WIMPs off of an atomic nucleus. The LUX collaboration uses confidence intervals determined via hypothesis test inversion to set limits on WIMP-nucleon couplings. These hypothesis tests are done using a profile likelihood ratio test statistic. This technique resulted in the LUX 2014 - 2016 (Run 4) data set yielding a world-leading limit on the WIMP-nucleon spin-independent interaction at WIMP masses of ~ 10s of GeV. A model-independent way of investigating WIMP-nucleon interactions is introduced utilizing Effective Field Theory. This framework introduces 14 possible allowed WIMP-nucleon couplings in the non-relativistic regime. Many of these couplings produce signals whose recoil spectra peak at energies above the threshold of our previous spin-independent search, and as such, an all-new analysis was developed to extend LUX's energy range and search for these couplings. Comparison of the LUX Run 4 data set to the models developed in this analysis yielded results that are inconsistent with the background-only model. However, inspection of the data suggests that this is due to an incomplete modeling of the electron recoil background, not due to the presence of a WIMP signal, and therefore only upper limits are reported. Additionally, efforts have been made to improve upon the LUX detector's technology for LZ via the construction of prototype detectors at the SLAC National Accelerator Laboratory.
Download or read book Effective Field Theories written by Alexey A Petrov and published by World Scientific. This book was released on 2015-11-18 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a broad-based text intended to help the growing student body interested in constructing and applying methods of effective field theory to solve problems in their research. It begins with a review of using symmetries to identify the relevant degrees of freedom in a problem, and then presents a variety of methods that can be used to construct various effective theories. A detailed discussion of canonical applications of effective field theory techniques with increasing complexity is given, including Fermi's weak interaction, heavy-quark effective theory, and soft-collinear effective theory. Applications of these techniques to study physics beyond the standard model, dark matter, and quantum and classical gravity are explored. Although most examples come from questions in high-energy physics, many of the methods can also be applied in condensed-matter settings. Appendices include various factoids from group theory and other topics that are used throughout the text, in an attempt to make the book self-contained.
Download or read book Finding What Works in Health Care written by Institute of Medicine and published by National Academies Press. This book was released on 2011-07-20 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: Healthcare decision makers in search of reliable information that compares health interventions increasingly turn to systematic reviews for the best summary of the evidence. Systematic reviews identify, select, assess, and synthesize the findings of similar but separate studies, and can help clarify what is known and not known about the potential benefits and harms of drugs, devices, and other healthcare services. Systematic reviews can be helpful for clinicians who want to integrate research findings into their daily practices, for patients to make well-informed choices about their own care, for professional medical societies and other organizations that develop clinical practice guidelines. Too often systematic reviews are of uncertain or poor quality. There are no universally accepted standards for developing systematic reviews leading to variability in how conflicts of interest and biases are handled, how evidence is appraised, and the overall scientific rigor of the process. In Finding What Works in Health Care the Institute of Medicine (IOM) recommends 21 standards for developing high-quality systematic reviews of comparative effectiveness research. The standards address the entire systematic review process from the initial steps of formulating the topic and building the review team to producing a detailed final report that synthesizes what the evidence shows and where knowledge gaps remain. Finding What Works in Health Care also proposes a framework for improving the quality of the science underpinning systematic reviews. This book will serve as a vital resource for both sponsors and producers of systematic reviews of comparative effectiveness research.

Download or read book The Perfect Slime written by Hans-Curt Flemming and published by IWA Publishing. This book was released on 2016-09-15 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Perfect Slime presents the latest state of knowledge and all aspects of the Extracellular Polymeric Substances, (EPS) matrix – from the ecological and health to the antifouling perspectives. The book brings together all the current material in order to expand our understanding of the functions, properties and characteristics of the matrix as well as the possibilities to strengthen or weaken it. The EPS matrix represents the immediate environment in which biofilm organisms live. From their point of view, this matrix has paramount advantages. It allows them to stay together for extended periods and form synergistic microconsortia, it retains extracellular enzymes and turns the matrix into an external digestion system and it is a universal recycling yard, it protects them against desiccation, it allows for intense communication and represents a huge genetic archive. They can remodel their matrix, break free and eventually, they can use it as a nutrient source. The EPS matrix can be considered as one of the emergent properties of biofilms and are a major reason for the success of this form of life. Nevertheless, they have been termed the “black matter of biofilms” for good reasons. First of all: the isolation methods define the results. In most cases, only water soluble EPS components are investigated; insoluble ones such as cellulose or amyloids are much less included. In particular in environmental biofilms with many species, it is difficult to impossible isolate, separate the various EPS molecules they are encased in and to define which species produced which EPS. The regulation and the factors which trigger or inhibit EPS production are still very poorly understood. Furthermore: bacteria are not the only microorganisms to produce EPS. Archaea, Fungi and algae can also form EPS. This book investigates the questions, What is their composition, function, dynamics and regulation? What do they all have in common?
Download or read book Living Well with Chronic Illness written by Institute of Medicine and published by National Academies Press. This book was released on 2011-06-30 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the United States, chronic diseases currently account for 70 percent of all deaths, and close to 48 million Americans report a disability related to a chronic condition. Today, about one in four Americans have multiple diseases and the prevalence and burden of chronic disease in the elderly and racial/ethnic minorities are notably disproportionate. Chronic disease has now emerged as a major public health problem and it threatens not only population health, but our social and economic welfare. Living Well with Chronic Disease identifies the population-based public health actions that can help reduce disability and improve functioning and quality of life among individuals who are at risk of developing a chronic disease and those with one or more diseases. The book recommends that all major federally funded programmatic and research initiatives in health include an evaluation on health-related quality of life and functional status. Also, the book recommends increasing support for implementation research on how to disseminate effective longterm lifestyle interventions in community-based settings that improve living well with chronic disease. Living Well with Chronic Disease uses three frameworks and considers diseases such as heart disease and stroke, diabetes, depression, and respiratory problems. The book's recommendations will inform policy makers concerned with health reform in public- and private-sectors and also managers of communitybased and public-health intervention programs, private and public research funders, and patients living with one or more chronic conditions.
