This book introduces the reader to the field of jet substructure, starting from the basic considerations for capturing decays of boosted particles in individual jets, to explaining state-of-the-art techniques. Jet substructure methods have become ubiquitous in data analyses at the LHC, with diverse applications stemming from the abundance of jets in proton-proton collisions, the presence of pileup and multiple interactions, and the need to reconstruct and identify decays of highly-Lorentz boosted particles. The last decade has seen a vast increase in our knowledge of all aspects of the field, with a proliferation of new jet substructure algorithms, calculations and measurements which are presented in this book. Recent developments and algorithms are described and put into the larger experimental context. Their usefulness and application are shown in many demonstrative examples and the phenomenological and experimental effects influencing their performance are discussed. A comprehensive overview is given of measurements and searches for new phenomena performed by the ATLAS and CMS Collaborations. This book shows the impressive versatility of jet substructure methods at the LHC.
This book opens up a new window into the Hellenistic world through a close study of mouldmade bowls, their places of production (both in the Black Sea and the Mediterranean), iconographies and distribution. The author’s unique access to material in the Black Sea Region provides the backbone to a rare comparative approach to an important type of vessel that traditionally has been studied in local isolation.
This concise primer reviews the latest developments in the field of jets. Jets are collinear sprays of hadrons produced in very high-energy collisions, e.g. at the LHC or at a future hadron collider. They are essential to and ubiquitous in experimental analyses, making their study crucial. At present LHC energies and beyond, massive particles around the electroweak scale are frequently produced with transverse momenta that are much larger than their mass, i.e., boosted. The decay products of such boosted massive objects tend to occupy only a relatively small and confined area of the detector and are observed as a single jet. Jets hence arise from many different sources and it is important to...
The Higgs boson discovery at the Large Hadron Collider in 2012 relied on boosted decision trees. Since then, high energy physics (HEP) has applied modern machine learning (ML) techniques to all stages of the data analysis pipeline, from raw data processing to statistical analysis. The unique requirements of HEP data analysis, the availability of high-quality simulators, the complexity of the data structures (which rarely are image-like), the control of uncertainties expected from scientific measurements, and the exabyte-scale datasets require the development of HEP-specific ML techniques. While these developments proceed at full speed along many paths, the nineteen reviews in this book offer a self-contained, pedagogical introduction to ML models' real-life applications in HEP, written by some of the foremost experts in their area.
Incompletion is an essential condition of cultural history, and particularly the idea of the fragment became a central element of Romantic art which continued being of high relevance to the various strands of modernist and contemporary aesthetics.

In der Psychologischen Beratung gilt es, einen Rahmen zur Verfügung zu stellen, um den Möglichkeitsraum von Krisen-Betroffenen zu öffnen und zu weiten. Hierbei unterstützt maßgeblich die logotherapeutische Haltung. Diese hat vor allem die Selbstkompetenzen der Betroffenen, die Ressourcen und Entwicklungspotentiale, und auch den geistigen Freiraum zur individuellen Beantwortung von schwierigen Lebensfragen, im Blick. Krisen machen nicht zwingend weniger, sondern vielfach mehr aus Menschen! Dies wird im Buch ausführlich anhand von Beispielen aus dem logotherapeutischen Praxisfeld beschrieben.
