Book Description
Inclusive electron scattering data are presented for 2H and Fe targets at an incident electron energy of 4.045 GeV for a range of momentum transfers from Q2 = 1 to 7 (GeV/c)2. Data were taken at Jefferson Laboratory for low values of energy loss, corresponding to values of Bjorken x greater than or near 1. The structure functions do not show scaling in x in this range, where inelastic scattering is not expected to dominate the cross section. The data do show scaling, however, in the Nachtmann variable [xi]. This scaling may be the result of Bloom Gilman duality in the nucleon structure function combined with the Fermi motion of the nucleons in the nucleus. The resulting extension of scaling to larger values of [xi] opens up the possibility of accessing nuclear structure functions in the high-x region at lower values of Q2 than previously believed.

Book Description
High Energy Physics and Nuclear Structure covers the proceedings of the Ninth International Conference on High Energy Physics and Nuclear Structure, held in Versailles on July 6-10, 1981. The book focuses on the processes, reactions, and methodologies involved in high energy physics and nuclear structure. The selection first offers information on experiments on antinucleon-nucleon, baryonium, nucleon-nucleon, and dibaryons and the quark model pion and the goldstone pion. Discussions focus on antinucleon-nucleon and baryonium, nucleon-nucleon and dibaryon, and spontaneous breaking of chiral symmetry. The text also ponders on quarks and nuclei, multiquark resonant states, and electron scattering from complex nuclei. The publication elaborates on electromagnetic interactions on light nuclei, electromagnetic interactions with nuclei at high momentum transfer, and inelastic electron scattering at low energy. The book also touches on the dynamics of hadron nucleus interactions, hypernuclei and interactions of kaons with nuclei, and pion-nucleus scattering theory. The selection is a dependable reference for readers interested in high energy structure and nuclear physics.

Book Description
Since publication of the first edition in 1995, there have been significant advances and understanding of chromatin structure and its relation to gene expression. These include a high-resolution structure of the nucleosome core, discovery of the enzymes and complexes that mediate histone acetylation and deacetylation, discovery of novel ATP-dependent chromatin remodeling complexes, new insights into nuclear organization and epigenetic silencing mechanisms. In light of these advances, Chromatin Structure and Gene Expression (2ed.) includes updated chapters and additional material that introduce new concepts in the process of gene regulation in chromatin.

Book Description
In this textbook, all known fundamental interactions are considered and the main directions of their unification are reviewed. The basic theoretical ideas and experiments, which permit establishing a quark-lepton level of matter structure are discussed. A general scheme for the theory of interacting fields with the help of the local gauge invariance principle is given. This scheme is used for presentation of the basic aspects of the quantum chromodynamics and electroweak theory of Weinberg-Salam-Glashow. Principles of operation and designs of accelerators, neutrino telescopes, and elementary particle detectors are considered. The modern theory of the Universe evolution is described.

Book Description
Ladies and Gentlemen, dear colleagues, Welcome in Bodrum to the NASion Hot and Dense Nuclear Matter! Welcome also to Mrs. Governor Dr. Lale AYTAMAN. We are very honored, that you, Governor of the Mugla-State, came here to greet us. We are particularly grateful to you that you offered help and assured us to do everything that we can enjoy two safe weeks in Bodrum, in this wonderful area of your country. I have chosen Bodrum as the place for our NASI because I like this historic region where many cultures meet (e. g. , Oriental and European (Greek, Roman) culture) and where you find numerous places which played a role in ancient science and in early Christianity- I mention Milet (Thales) and Ephesus (Apostle Paulus), both of which are close by. Our NASI will exhibit the most recent developments in high energy heavy ion physics. The meeting is both a school and a conference: A school, because there are very many advanced students, who frequently are themselves already top researchers, attending the lectures of distinguished scientists and leading researchers. It is also a conference because new material, new results of this exciting and wonderful field - our field - high energy heavy ion physics will be presented. It is the topic of hot and dense nuclear matter, which we are focusing on.

Book Description
The Landau Institute for Theoretical Physics was created in 1965 by a group of LD Landau's pupils. Very soon, it was widely recognized as one of the world's leading centers in theoretical physics. According to Science Magazine, the Institute in the eighties had the highest citation index among all the scientific organizations in the former Soviet Union. This collection of the best papers of the Institute reflects the development of the many directions in the exact sciences during the last 30 years. The reader can find the original formulations of well-known notions in condensed matter theory, quantum field theory, mathematical physics and astrophysics, which were introduced by members of the Landau Institute.The following are some of the achievements described in this book: monopoles (A Polyakov), instantons (A Belavin et al.), weak crystallization (S Brazovskii), spin superfluidity (I Fomin), finite band potentials (S Novikov) and paraconductivity (A Larkin, L Aslamasov).

Book Description
During July 1990. a group of 83 physicists from 43 laboratories in 21 countries met in Erice for the 28th Course of the International School of Subnuclear Physics. The countries represented were: Algeria. Canada. Chile. China. Czechoslovakia. Denmark. France. the Federal Republic of Germany. Greece. Holland. India. Italy. Pakistan. Peru. Poland. Sweden. Switzerland. Turkey. the Union of Soviet Socialist Republics. the United Kingdom. and the United States of America. The School was sponsored by the European Physical Society (EPS). the Italian Ministry of Education (MPI). the Italian Ministry of University and Scientific Research. the Sicilian Regional Government (ERS). and the Weizmann Institute of Science. The new topic discussed in some detail at the School was QCD phenomenology at 200 TeV. This energy frontier represents the goal for subnuclear physics after LHC and sse. The main lecturers were T.D. Lee. L. Cifarelli. Y. Dokshitzer and A. Ringwald. There are two possibilities. one optimistic. the other pessimistic. LHC and SSC can produce remarkable discoveries. In this case. the need to go to higher energies will be obvious. In the pessimistic case. LHC and SSC will produce the strongest evidence for the validity of the Standard Model. The need for higher energies will be impelled. In neither case can we wait. If the 200 TeV frontier is to be reached within our lifetime we need to start now: thinking and preparing the tools. Theory and R&D for future detectors are the basic points of the 200 TeV frontier.
