This thesis describes two groundbreaking measurements in the precision frontier at the LHC: the first ever differential measurement of the Z-associated single top quark (tZq) production, and the luminosity measurement using Z boson production rate for the first time in CMS. Observed only in 2018, the tZq process is of great importance in probing top quark electroweak couplings. These couplings are natural places for new phenomena to happen in the top quark sector of the standard model. Yet, they are the least explored directly. One has to obtain a firm understanding of the modeling of sensitive distributions to new top-Z interactions. The present analysis marks a major milestone in this long-term effort. All distributions relevant for new phenomena, and/or modeling of tZq, are studied in full depth using advanced Machine Learning techniques.The luminosity and its uncertainty contributes to every physics result of the experiment. The method minutely developed in this thesis provides a complementary measurement that results in a significant overall reduction of uncertainties.
The book reports on the author's original work to address the use of today's state-of-the-art smartphones for human physical activity recognition.
This thesis describes the first detection of a nuclear transition that had been sought for 40 years, and marks the essential first step toward developing nuclear clocks. Still, they could potentially be outperformed by nuclear clocks, based on a nuclear transition instead of the atomic transitions employed to date.
These various compositional elements have the potential to inhibit cancer cell activity whilst doing no harm to healthy cells. In particular in glioma therapy, CAP could offer an innovative approach allowing specific cancer cell / tumor tissue inhibition without damaging healthy cells.
Despite more than half a century of theoretical work, the Casimir effect is still not as fully understood as some suppose. In particular, he clearly demonstrates that the most sophisticated theories fail when confronted with dielectrics in which the refractive index is not uniform but gradually changes.
Lena Daumanns's thesis describes structural and functional studies of the enzyme Glycerophosphodiesterase (GpdQ) from Enterobacter aerogenes. Overall, this project has led to a better understanding of the metal ion binding and active site structural features of the enzyme GpdQ.
This book presents a comprehensive mathematical approach for solving stochastic magnetic field problems.
This thesis describes in detail a search for weakly interacting massive particles as possible dark matter candidates, making use of so-called mono-jet events.
This book reports on a set of new techniques for resolving current issues in networked control systems. This thesis, examined at the Universidad Nacional de Educacion a Distancia in 2013, received the award for best thesis in control engineering from the Control Engineering group of the Spanish Committee of Automatic Control in 2015.
This thesis presents a qualitative advance in our understanding of quantum effects in layered magnetic materials. It has long been established that in one dimension quantum fluctuations lead to a quantum disordered ground state with fractional excitations called spinons."
This thesis presents a general approach to accessing nitrogen-substituted hetero- and carbocycles. In short, the annulation reactions developed in the thesis make it possible to access nitrogen-substituted four-, five- and six-membered rings, all essential building blocks for the synthesis of bioactive molecules.
This work addresses the computation of excited-state properties of systems containing thousands of atoms.
This interdisciplinary approach to analyzing manufactured tool steels in the gigacycle range provides invaluable detail on fatigue behavior. The book deploys techniques from materials science, metallurgy, chemistry, physics and mechanical engineering.
This thesis presents the results of indirect dark matter searches in the gamma-ray sky of the near Universe, as seen by the MAGIC Telescopes.
This book mainly investigates the precision predictions on the signal of new physics at the Large Hadron Collider (LHC) in the perturbative Quantum Chromodynamics (QCD) scheme. The potential of the LHC to discover the signal of dark matter associated production with a photon is studied after including next-to-leading order QCD corrections.
Using three classes of polymer composites as illustrative examples, this book shows that the interactions of components can cause unpredictable structural effects, ultimaltely leading to a weakening of the material, where a reinforcement was expected.
This book develops a detailed, quantitative theory of NMR 1/T1 relaxation rates and shows how they could be used to measure the speed at which energy travels in a wide range of magnetic materials.
In this thesis, the author investigates the biophysical basis of the local field potential (LFP) as a way of gaining a better understanding of its underlying physiological mechanisms.
This research contributes to the growing body of knowledge as well as offers significant theoretical contributions and policy implications.
This book examines Au (I, III) complexes that selectively attack and inhibit zinc finger proteins (ZnFs) for potential therapeutic use.
This book sheds new light on the dynamical behaviour of electron spins in molecules containing two unpaired electrons (i.e.
In this book, the equilibrium and nonequilibrium properties of continuous phase transitions are studied in various systems, with a special emphasis on understanding how well-established universal traits at equilibrium may be extended into the dynamic realm, going beyond the paradigmatic Kibble-Zurek mechanism of defect formation.
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.
This thesis investigates the behavior of two candidate materials (a-SiO2 and MgO) for applications in fusion (e.g., the International Thermonuclear Experimental Reactor ITER) and Generation IV fission reactors.
In addition to critical new results on the direct growth of 2D heterostructures, it also details growth mechanisms, surface science, and device applications of "epi-grade" 2D semiconductors, which are essential to low-power electronics, as well as for extending Moore's law.
This thesis describes in-depth theoretical efforts to understand the reaction mechanism of graphite and lithium metal as anodes for next-generation rechargeable batteries.
This book addresses new ways to optimize the fabrication process and performance of iron-based superconducting wires and tapes based on the powder-in-tube (PIT) method. This book will greatly benefit all students, researchers, and technical personnel who work in superconducting materials, applied superconductivity, and the power industry.
