Higgs, Supersymmetry and Dark Matter After Run I of the LHC

by Béranger Dumont

This work was nominated as an outstanding PhD thesis by the LPSC, Université Grenoble Alpes, France. The LHC Run 1 was a milestone in particle physics, leading to the discovery of the Higgs boson, the last missing piece of the so-called "Standard Model" (SM), and to important constraints on new physics, which challenge popular theories like weak-scale supersymmetry.This thesis provides a detailed account of the legacy of the LHC Run 1 ≤¥regarding these aspects. First, the SM and the need for its extension are presented in a concise yet revealing way. Subsequently, the impact of the LHC Higgs results on scenarios of new physics is assessed in detail, including a careful discussion of the relevant uncertainties. Two approaches are considered: generic modifications of the Higgs couplings, possibly arising from extended Higgs sectors or higher-dimensional operators; and tests of specific new physics models. Lastly, the implications of the null results of the searches for new physics are discussed with a particular focus on supersymmetric dark matter candidates. Here as well, two approaches are presented: the "simplified models" approach, and recasting by event simulation. This thesis stands out for its educational approach, its clear language and the depth of the physics discussion. The methods and tools presented offer readers essential practical tools for future research.

High Accuracy Surface Modeling Method: The Robustness

by Na Zhao TianXiang Yue

This book focuses on the robustness analysis of high accuracy surface modeling method (HASM) to yield good performance of it. Understanding the sensitivity and uncertainty is important in model applications. The book aims to advance an integral framework for assessing model error that can demonstrate robustness across sets of possible controls, variable definitions, standard error, algorithm structure, and functional forms. It is an essential reference to the most promising numerical models. In areas where there is less certainty about models, but also high expectations of transparency, robustness analysis should aspire to be as broad as possible. This book also contains a chapter at the end featuring applications in climate simulation illustrating different implementations of HASM in surface modeling. The book is helpful for people involved in geographical information science, ecological informatics, geography, earth observation, and planetary surface modeling.

High Altitude Primates

by Nanda B. Grow Sharon Gursky-Doyen Alicia Krzton

The basic goal of the volume is to compile the most up to date research on how high altitude affects the behavior, ecology, evolution and conservation status of primates, especially in comparison to lowland populations. Historically, the majority of primate studies have focused on lowland populations. However, as the lowlands have been disappearing, more and more primatologists have begun studying populations located in higher altitudes. High altitude populations are important not only because of their uniqueness, but also because they highlight the range of primate adaptability and the complex variables that are involved in primate evolution. These populations are good examples of how geographic scales result in diversification and/or speciation. Yet, there have been very few papers addressing how this high altitude environment affects the behavior, ecology, and conservation status of these primates. ​

High- and Low-Valent tris-N-Heterocyclic Carbene Iron Complexes

by Carola S. Vogel

Carola Vogel's PhD thesis focuses on the synthesis, and structural and spectroscopic characterization of the first high valent iron nitride complexes. In her interdisciplinary and collaborative research Carola also describes the reactivity studies of a unique iron (V) nitride complex with water. These studies show that quantitative yields of ammonia are given at ambient conditions. High valent iron nitride and oxo species have been proposed as key intermediates in many bio-catalytic transformations, but until now these species have proven exceedingly challenging to isolate and study. Iron complexes in high oxidation states can thus serve as models for iron-containing enzymes to help us understand biological systems or aid our development of more efficient industrial catalysts.

High Calling: The Courageous Life and Faith of Space Shuttle Columbia Commander Rick Husband

by Evelyn Husband Donna Vanliere

Rick Husband wanted to be an astronaut since his fourth birthday, but it wasn't always for the right reasons. Initially, he thought it would be neat . . . cool . . . a fun thing to do. It wasn't until he came to a spiritual crossroads and was able to give that dream up to discover the true desires of his heart before he actually got into the space shuttle program at NASA. Three failed attempts didn't daunt this driven pilot-and the fourth interview process, though lengthy and difficult, proved successful for him. Husband's years at NASA served not only to develop his integrity and character, but also to increase his faith in a Creator that could not be denied in the vastness of space. His story is not only inspirational but exhilarating and invigorating, as readers will witness the life of a man who consistently pursued the desires of his heart even as he served a faithful God.

High-Conductivity Channels in Space (Springer Series on Atomic, Optical, and Plasma Physics #103)

by Victor Apollonov

This book discusses the physics of conductive channel development in space, air and vacuums and summarizes the attempts to create super-long conductive channels to study the upper atmosphere and to complete specific tasks related to energy transmission from the space to earth with high-voltage high repetition rate electrical sources. Conductive channels are produced by the laser jet engine vehicle-propulsion under the influence of powerful high repetition rate pulse-periodic laser radiation by CO2-laser, solid state Nd YAG,HF/DF laser systems generated with each pulse of the powerful laser conductive dust plasma. The book also presents the experimental and theoretical results of conductive canal modeling: the laser jet engine vehicle “Impulsar”, which can reach the lower layers of the ionosphere in several hundred seconds. Further, the book explores the development of lightning protection systems. The so-called long laser spark is generated to provide the conditions for connecting a thunderstorm cloud with a grounded metal rod, i.e. a classical lightning rod. Such conductivity channels can be used for energy transmission, overvoltage protection systems, transport of charged particle beams and plasma antennas. It provides the theoretical and experimental basis of high repetition rate P-P mode of operation for high power lasers (COIL, HF/DF, CO2,Nd YAG). It describes high efficiency and excellent beam quality disk lasers used for numerous applications, including surface treatment of dielectric materials in microelectronics, cutting, drilling, welding, polishing and cleaning of the surface and other technological operations. Lastly it investigates how megawatt mono-module disk lasers could be used to solve various problems: small satellites launched by lasers, formation of super-long conducting channels in space and atmosphere, cleaning of the near-earth space from the space debris and related applications.

High-Density Lipoproteins as Biomarkers and Therapeutic Tools: Volume 1. Impacts of Lifestyle, Diseases, and Environmental Stressors on HDL

by Kyung-Hyun Cho

This book is the first of two volumes that offer a comprehensive, up-to-date account of current knowledge regarding high-density lipoprotein (HDL), the changes that occur in HDL under different conditions, the clinical applications of HDL, and means of enhancing HDL functionality. HDL comprises a diverse group of lipoproteins and its composition and metabolism are dynamic. In this volume, the focus is on the changes observed in HDL under different health statuses, with particular attention to the functional and structural correlations of HDL and apolipoprotein A-1. The impacts of a wide variety of factors on HDL are examined in depth, covering, for example, diet, exercise, smoking, age, diverse diseases, and different forms of environmental pollution. It has long been known that HDL has anti-atherosclerotic and antidiabetic properties, and more recently its anti-aging activities have been recognized. These benefits of HDL are highly dependent on its lipids, proteins, apolipoproteins, and enzymes, and specifically their composition and ratios. In documenting the latest knowledge in this field, this volume will be of interest to both researchers and clinicians.

High-dimensional Microarray Data Analysis: Cancer Gene Diagnosis and Malignancy Indexes by Microarray

by Shuichi Shinmura

This book shows how to decompose high-dimensional microarrays into small subspaces (Small Matryoshkas, SMs), statistically analyze them, and perform cancer gene diagnosis. The information is useful for genetic experts, anyone who analyzes genetic data, and students to use as practical textbooks.Discriminant analysis is the best approach for microarray consisting of normal and cancer classes. Microarrays are linearly separable data (LSD, Fact 3). However, because most linear discriminant function (LDF) cannot discriminate LSD theoretically and error rates are high, no one had discovered Fact 3 until now. Hard-margin SVM (H-SVM) and Revised IP-OLDF (RIP) can find Fact3 easily. LSD has the Matryoshka structure and is easily decomposed into many SMs (Fact 4). Because all SMs are small samples and LSD, statistical methods analyze SMs easily. However, useful results cannot be obtained. On the other hand, H-SVM and RIP can discriminate two classes in SM entirely. RatioSV is the ratio of SV distance and discriminant range. The maximum RatioSVs of six microarrays is over 11.67%. This fact shows that SV separates two classes by window width (11.67%). Such easy discrimination has been unresolved since 1970. The reason is revealed by facts presented here, so this book can be read and enjoyed like a mystery novel. Many studies point out that it is difficult to separate signal and noise in a high-dimensional gene space. However, the definition of the signal is not clear. Convincing evidence is presented that LSD is a signal. Statistical analysis of the genes contained in the SM cannot provide useful information, but it shows that the discriminant score (DS) discriminated by RIP or H-SVM is easily LSD. For example, the Alon microarray has 2,000 genes which can be divided into 66 SMs. If 66 DSs are used as variables, the result is a 66-dimensional data. These signal data can be analyzed to find malignancy indicators by principal component analysis and cluster analysis.

High Dimensional Space to Formulate Marriage and Birth Functions

by Shuichirou Ike

With the collapse of Demographic Transition Theory, new theories of population must not just be explanations, but should be falsifiable theories which can compute the number of occurrences of marriages and births. This book reviews computable marriage and birth function using dynamic properties. To do that, the functions are defined in high dimensional space. The reaction-diffusion equation of the number of children in a space is applied to these phenomena, providing solutions to many problems concerning a decline in fertility. The functions are developed as stochastic maps based on the present behaviors of successive behaviors in a geographical space. As we assume that there is an inter-dependence of human behaviors, we use the law of dynamics concerning the function of marriage and birth. The exact mathematical definition of interactions in a space naturally implies a causal relation. For the function concerning the number of children of parents, two geographical-dimensional spaces are required. The decline in fertility in Belgium due to different languages is explained, and the longer fertility period in Brittany is explained by the Laplacian of the diffusion equation. Depending on the degree of symbolic control over behaviors, we need to add the degree of the dimension of the space. For the marriage function, we add age as a biological dimension to the geographical space. In this higher dimensional space, the mapping from neighboring present marriages to neighboring successive marriages is no less than that of the marriage function. These chain reactions caused the baby boom as an exothermal reaction-diffusion. Birth functions require one to add the marriage-age dimension to two geographical and age dimensions so that it is a five dimensional hypersurface. It can, thus, determine birth probabilities of a female who married at a certain age. The phenomenon of modern fertility decline may only be the result of these chain reactions. These processes are solely dependent upon time-space, and not on socioeconomic conditions. This is the very reason why we are able to predict it mathematically. The book provides a new thinking in fertility decline for demographic research. Readers need to be aware that the fertility decline experienced throughout the modern era is a spatial pattern formation (as a reaction-diffusion). The author hopes new mathematical applications in human activities are developed through these new models.

High Energy Astrophysical Neutrinos (SpringerBriefs in Astronomy)

by Debanjan Bose Subhendu Rakshit

This book provides a pedagogical introduction to the likely sources of these neutrinos, their propagation and detection mechanisms. Detection of high energy neutrinos of extragalactic origin has led to an interdisciplinary field of research, involving astronomy, astrophysics and particle physics. An extensive review of various detectors and the observations is provided that consolidates the latest findings. Above a few tens of TeVs, neutrinos are conceived as more reliable messengers for astronomy than photons as these photons get absorbed in the background photon field. Determining the neutrino spectrum not only helps in exploring astrophysical objects like AGN, GRB, etc. but also allows us to study particle physics at unprecedented energies. This introductory book is intended to help advanced undergraduate and graduate students to get into the subject with ease, and it simultaneously caters to practicing theoretical or experimental physicists as a reference book.

High-Energy Atomic Physics

by Evgeny G. Drukarev A. I. Mikhailov

This self-contained text introduces readers tothe field of high-energy atomic physics - a new regime of photon-atominteractions in which the photon energies significantly exceed the atomic ormolecular binding energies, and which opened up with the recent advent of newsynchrotron sources. From a theoretical point of view, a small-parametercharacteristic of the bound system emerged, making it possible to performanalytic perturbative calculations that can in turn serve as benchmarks formore powerful numerical computations. The first part of the book introduces readersto the foundations of this new regime and its theoretical treatment. Inparticular, the validity of the small-parameter perturbation expansion and ofthe lowest-order approximation is critically reviewed. The following chaptersthen apply these insights to various atomic processes, such as photoionizationas a many-body problem, dominant mechanisms for the production of ions athigher energies, Compton scattering and ionization accompanied by creation ofe-e+ pairs, and the photoionization of endohedral atoms (e. g. fullerene). Lastbut not least, the computationally challenging transitions in the electronshell during certain types of nuclear decays are investigated in detail.
