Book Description
This thesis addresses in a very new and elegant way several measurements and the extraction of so-called double parton scattering. The new and elegant way lies in the combination of measurements and a very smart extraction of double parton scattering results, which is easy to apply and overcomes many of the technical difficulties of older methods. Many new phenomena in particle physics can be observed when particles are collided at the highest energies; one of the highlights in recent years was the discovery of the Higgs boson at the Large Hadron Collider at CERN. Understanding the production mechanism of the Higgs boson at the LHC requires detailed knowledge of the physics of proton-proton collisions. When the density of partons in the protons becomes large, there is a non-negligible probability that more than one parton participates in the interaction and the so-called double parton scattering becomes important. In some cases very particular final state signatures can be observed, which can be regarded as an indication of such double partonic scattering and where the different interactions can be separated. Such multiple partonic interactions play an important role when precise predictions from known processes are required.

Book Description
This book presents two analyses, the first of which involves the search for a new heavy charged gauge boson, a so-called W' boson. This new gauge boson is predicted by some theories extending the Standard Model gauge group to solve some of its conceptual problems. Decays of the W' boson in final states with a lepton (l± = e± , μ±) and the corresponding (anti-)neutrino are considered. Data collected by the ATLAS experiment in 2015 at a center of mass energy of √s =13 TeV is used for the analysis. In turn, the second analysis presents a measurement of the double-differential cross section of the process pp->Z/gamma^* + X -> l^+l^- + X, including a gamma gamma induced contribution, at a center of mass energy of sqrt{s} = 8 TeV. The measurement is performed in an invariant mass region of 116 GeV to 1500 GeV as a function of invariant mass and absolute rapidity of the l^+l^-- pair, and as a function of invariant mass and pseudorapidity separation of the l^+l^-- pair. The data analyzed was recorded by the ATLAS experiment in 2012 and corresponds to an integrated luminosity of 20.3/fb. It is expected that the measured cross sections are sensitive to the PDFs at very high values of the Bjorken-x scaling variable, and to the photon structure of the proton.

Book Description
Goldfrank’s is the premier toxicology textbook that should be in every emergency department or poison center library. Whether you are a student, resident, or faculty, there is something here for you. If you are a toxicology fellow or poison specialist studying for your boards, this is your go-to book. I highly recommend this work... —The Journal of Emergency Medicine The best edition yet of the landmark text in medical toxicology A Doody’s Core Title for 2021! Covering every aspect of poison management, this indispensable case-based resource has been thoroughly refreshed to deliver evidence-based principles viewed through the lens of an active bedside clinical practice. In no other reference will you find such a diverse roster of esteemed editors and authors who deliver expert insights into every type of toxicologic emergency, whether due to substance abuse or exposure to toxins. Fully referenced and supported by a cohesive organization and full-color format, Goldfrank’s begins with a historical perspective on medical toxicology principles and the general approach to the patient. It then progresses to the fundamental principles of medical toxicology, encompassing biochemical and molecular concepts; the effect of xenobiotics on vital organs and body systems; and toxicologic principles in special populations. The Eleventh Edition of Goldfrank’s Toxicologic Emergencies is the most rigorous volume to date, driven by a precise analysis of the latest medical literature and complex cases designed to facilitate differential diagnosis. New to this Edition: • Additional cases and “Special Considerations” chapters designed to enhance clinical decision-making and patient outcomes • New “Antidotes in Depth” provides timely, critical information on toxicologic treatment strategies • New content on toxicogenomics explores its increasingly important role in predictive toxicology • Chapter-ending bulleted summaries of key points • Updated coverage of synthetics such as “K2” • Revised chapters on medical, clinical, and chemical toxicology include updated insights on poison emergencies, treatment strategies, and risk assessment tools
