Reference Data 139 Outline -1- / Outline of two projects Fundamental Principles Underlying the Hierarchy of Matter: A Comprehensive Experimental Study / • Outline of the Project This five-year project lead by Dr. R. Kato is the collaborative effort of eight laboratories, in which we treat the hierarchy of matter from hadrons to biomolecules with three underlying and interconnected key concepts: interaction, excitation, and heterogeneity. The project consists of experimental research conducted using cutting-edge technologies, including lasers, signal processing and data acquisition, and particle beams at RIKEN RI Beam Factory (RIBF) and RIKEN Rutherford Appleton Laboratory (RAL). • Physical and chemical views of matter lead to major discoveries Although this project is based on the physics and chemistry of non-living systems, we constantly keep all types of matter, including living matter, in our mind. The importance of analyzing matter from physical and chemical points of view was demonstrated in the case of DNA. The Watson-Crick model of DNA was developed based on the X-ray diffraction, which is a physical measurement. The key feature of this model is the hydrogen bonding that occurs between DNA base pairs. Watson and Crick learned about hydrogen bonding in the renowned book “The Nature of the Chemical Bond,” written by their competitor, L. -

E-mail: [email protected] Abstract. In this talk I discuss aspects of hadron physics, which soon are expected to shed new light on the fundamental QCD phenomena. In the analysis of hadron reactions and their propertieds I emphasize similarities to the nuclear many body problem. 1. Introduction The vast majority of nuclear phenomena can be understood using protons and neutrons as elementary constituents and the nonrelativistic interactions among them. On the other hand, Quantum Chromodynamics (QCD), which is the underlying theory of nuclear forces, describes the relativistic quarks and gluons as the fundamental degrees of freedom. -

Available from the National Technical Information Service, U.S. Department of Commerce, 5285 Port Royal Road, Springfield, Virginia 22161. * Ph.D. thesis ii Abstract This thesis consists of two independent parts; development of Cherenkov Ring Imaging Detector (GRID) system and analysis of high-statistics data of strange meson reactions from the LASS spectrometer. Part I: The CIUD system is devoted to charged particle identification in the SLAC Large Detector (SLD) to study e+e- collisions at ,/Z = mzo. By measuring the angles of emission of the Cherenkov photons inside liquid and gaseous radiators, r/K/p separation will be achieved up to N 30 GeV/c. The signals from CRID are read in three coordinates, one of which is measured by charge-division technique. To obtain a N 1% spatial resolution in the charge- division, low-noise CRID preamplifier prototypes were developed and tested re- sulting in < 1000 electrons noise for an average photoelectron signal with 2 x lo5 gain. To help ensure the long-term stability of CRID operation at high efficiency, a comprehensive monitoring and control system was developed. This system contin- uously monitors and/or controls various operating quantities such as temperatures, pressures, and flows, mixing and purity of the various fluids. -

In the current study, we have experimentally and comparatively investigated and compared malignant human cancer cells and tissues before and after irradiating of synchrotron radiation using Hadron spectroscopy, Baryon spectroscopy and Meson spectroscopy. It is clear that malignant human cancer cells and tissues have gradually transformed to benign human cancer cells and tissues under synchrotron radiation with the passing of time (Figures 1-3) [1-198]. It can be concluded that malignant human cancer cells and tissues have gradually transformed to benign human cancer cells and tissues under synchrotron radiation with the passing of time (Figures 1-3) [1- 198].

Time–Resolved Resonance FT–IR and Raman Spectroscopy And
Global Imaging Insights Image ISSN: 2399-7397 Time–resolved resonance FT–IR and raman spectroscopy and density functional theory investigation of vibronic– mode coupling structure in vibrational spectra of nano- polypeptide macromolecule beyond the multi–dimensional franck–condon integrals approximation and density matrix method Alireza Heidari1,2*, Jennifer Esposito1 and Angela Caissutti1 1Faculty of Chemistry, California South University, 14731 Comet St. Irvine, CA 92604, USA 2American International Standards Institute, Irvine, CA 3800, USA Abstract A macromolecule is a very large molecule, such as protein, commonly created by the polymerization of smaller subunits (monomers). They are typically composed of thousands of atoms or more. The most common macromolecules in biochemistry are biopolymers (nucleic acids, proteins, carbohydrates and lipids) and large non–polymeric molecules (such as lipids and macrocycles). Synthetic macromolecules include common plastics and synthetic fibers as well as experimental materials such as carbon nanotubes. Parameters such as FT –IR and Raman vibrational wavelengths and intensities for single crystal Nano polypeptide macromolecule are calculated using density functional theory and were compared with empirical results. The investigation about vibrational spectrum of cycle dimers in crystal with carboxyl groups from each molecule of acid was shown that it leads to create Hydrogen bonds for adjacent molecules. The current study aimed to investigate the possibility of simulating the empirical values. Analysis of vibrational spectrum of Nano polypeptide macromolecule is performed based on theoretical simulation and FT–IR empirical spectrum and Raman empirical spectrum using density functional theory in levels of HF/6–31G*, HF/6–31++G**, MP2/6–31G, MP2/6– 31++G**, BLYP/6–31G, BLYP/6–31++G**, B3LYP/6–31G and B3LYP6–31–HEG**. -

Living on a dS brane: Effects of KK modes on inflation Claudia de Rham1,2, ∗ and Scott Watson3, † 1Dept. of Physics & Astronomy, McMaster University, Hamilton ON, Canada 2Perimeter Institute for Theoretical Physics, Waterloo, ON, Canada 3Physics Department, University of Toronto, Toronto, ON, Canada (Dated: February 2, 2008) We develop a formalism to study non-local higher-dimensional effects in braneworld sce- narios from a four-dimensional effective theory point of view and check it against the well- known Garriga-Tanaka result in the appropriate limit. We then use this formalism to study the spectrum of density perturbations during inflation as seen from the lower-dimensional effective theory. In particular, we find that the gravitational potential is greatly enhanced at short wavelengths. The consequences to the curvature perturbations are nonetheless very weak and will lead to no characteristic signatures on the power spectrum.
