Описание: Abstract: Renormalizations, which sum classes of diagrams to all orders in perturbation theory, are applied to the electron propagator. The separation of relaxation and correlation self-energy diagrams enables the construction of electron propagators that include relaxation contributions to all orders. Correlation self-energies are obtained in second order, third order, and in the diagonal 2p-h Tamm-Dancoff approximation, which is also a renormalization. These propagators are applied to the electron binding energies of CN, NFL, PFL and Cl2. An alternative propagator renormalization through the transition operator method reference state is applied to the electron binding energies of Ne, FLO, Ne, H2O, NH2, and CN. The anti symmetrized geminal power wavefunction, which is the form of the consistent ground state of the random phase approximation of the polarization propagator, is variationally optimized for the LiH groundstate potential curve. Random phase approximation polarization propagator calculations yield excitation energies. Physical concepts suggested by these theories are discussed.

Описание: This book covers the state-of-the-art of modern MALDI (matrix-assisted laser desorption/ionization) and its applications. New applications and improvements in the MALDI field such as biotyping, clinical diagnosis, forensic imaging, and ESI-like ion production are covered in detail. Additional topics include MS imaging, biotyping/speciation and large-scale, high-speed MS sample profiling, new methods based on MALDI or MALDI-like sample preparations, and the advantages of ESI to MALDI MS analysis. This is an ideal book for graduate students and researchers in the field of bioanalytical sciences. This book also: • Showcases new techniques and applications in MALDI MS • Demonstrates how MALDI is preferable to ESI (electrospray ionization) • Illustrates the pros and cons associated with biomarker discovery studies in clinical proteomics and the various application areas, such as cancer proteomics

Описание: The principal goal of this book is to provide state-of-the-art coverage of the non-relativistic three-body theory of high-energy ion-atom collisions. The main aspects of generalizations to tissue-like molecular targets, such as water, are also outlined. The focus is on the most frequently studied two processes, single electron capture and ionization. For the studied collisions, the literature has seen enormous renewal of activity in the development and applications of quantum-mechanical theories. This subject is of great relevance in several branches of science and technology, such as accelerator-based physics, research in new sources of energy and high temperature fusion of light ions. Other important applications are in the life sciences and medicine, where high-energy ion beams are used in cancer therapy. Therefore, it is necessary to present this field in its full capacity with the primary emphasis on realistic prospects for multidisciplinary applications, especially in radiotherapy.The present book is aimed to match the growing demand from theory and experiment, as motivated by high relevance for fundamental physics as well as for other fields such as fusion, medicine, etc. The overall emphasis in this book is not on compilation of cross sections, but rather on collisional mechanisms involving ions and atoms at high non-relativistic energies. The principal outlines for extensions of the analyzed theories' molecular targets (e.g. water) are also presented for the needs of hadron therapy.
