Group theoretical concepts elucidate fundamental physical phenomena, including excitation spectra of quantum systems and complex geometrical structures such as molecules and crystals. These concepts are extensively covered in numerous textbooks. The aim of the present monograph is to illuminate more subtle aspects featuring group theory for quantum mechanics, that is, the concept of dynamical symmetry. Dynamical symmetry groups complement the conventional groups: their elements induce transitions between states belonging to different representations of the symmetry group of the Hamiltonian. Dynamical symmetry appears as a hidden symmetry in the hydrogen atom and quantum rotator problem, but its main role is manifested in nano and meso systems. Such systems include atomic clusters, large molecules, quantum dots attached to metallic electrodes, etc. They are expected to be the building blocks of future quantum electronic devices and information transmitting algorithms. Elucidation of the electronic properties of such systems is greatly facilitated by applying concepts of dynamical group theory.
A key question for the contemporary world: What is Putin’s ideology? This book analyses this ideology, which it terms “Putinism”. It examines a range of factors that feed into the ideology – conservative thought in Russia from the nineteenth century onwards, Russian and Soviet history and their memorialisation, Russian Orthodox religion and its political connections, a focus on traditional values, and Russia’s sense of itself as a unique civilisation, different from the West and due a special, respected place in the world. The book highlights that although the resulting ideology lacks coherence and universalism comparable to that of Soviet-era Marxism-Leninism, it is nevertheless effective in aligning the population to the regime and is flexible and applicable in different circumstances. And that therefore it is not attached to Putin as a person, is likely to outlive him, and is potentially appealing elsewhere in the world outside Russia, especially to countries that feel belittled by the West and let down by the West’s failure to resolve problems of global injustice and inequality.
The authors introduce and study the class of groups graded by root systems. They prove that if is an irreducible classical root system of rank and is a group graded by , then under certain natural conditions on the grading, the union of the root subgroups is a Kazhdan subset of . As the main application of this theorem the authors prove that for any reduced irreducible classical root system of rank and a finitely generated commutative ring with , the Steinberg group and the elementary Chevalley group have property . They also show that there exists a group with property which maps onto all finite simple groups of Lie type and rank , thereby providing a “unified” proof of expansion in these groups.
Phase transitions and critical phenomena in liquids and liquid crystals have been the subject of intensive research since the 1960s. However, books on this fascinating subject have tended to be written by theorists for theorists. Professor Anisimov offers us a new approach: he aims to introduce experimentalists to the modern theories and their applications. After introducing the thermodynamics of phase transitions, he presents the modern theory of critical phenomena. He then concludes by illustrating the utility of this theory in the analysis of experimental measurements in classical fluids and binary mixtures, superfluid mixtures of helium isotopes and liquid crystals. Not only will this book be enjoyed by experimental physicists, chemists and material scientists, it will also offer the theorist an insight into the interpretation of the experimentalist's work.
A NEW YORKER BEST BOOK OF THE YEAR From “one of Russia’s smartest and best-sourced young journalists” (The New York Times)—the first work by a Russian author to reveal his country’s history of oppressing Ukraine, providing an unprecedented overview of the war for Ukrainian independence that affects us all. As soon as the Russian invasion of Ukraine began, prominent independent Russian journalist Mikhail Zygar circulated a Facebook petition signed first by hundreds of his cultural and journalistic contacts and then by thousands of others. That act led to a new law in Russia criminalizing criticism of the war, and Zygar fled Russia. In his time as a journalist, Zygar has interviewed President Zelensky and had access to many of the major players—from politicians to oligarchs. As an expert on Putin’s moods and behavior, he has spent years studying the Kremlin’s plan regarding Ukraine, and here, in clear, chronological order he explains how we got here. In 1996 to 2004, Ukraine became an independent post-Soviet country where everyone was connected to the former empire at all levels, financially, culturally, psychologically. However, the elite anticipated that the empire would be back and punish them. From 2004 to 2018, there were many states inside one state, each with its own rulers/oligarchs and its own interests—some of them directly connected with Russia. In 2018, a new generation of Ukrainians arrive, and having grown in an independent country, they do not consider themselves to be part of Russia—and that was the moment when the war began, as Putin could not tolerate losing Ukraine forever. Authoritative, timely, and vitally important, this is an unique overview of the war that continues to threaten the future of the entire world as we know it.

The book presents solutions to a complex of internal and external problems of electromagnetics associated with the development of theory, construction of mathematical models and the development of rigorous methods for calculating the electrodynamic characteristics of combined vibrator-slot structures. The solutions of problems for determining the characteristics of impedance vibrator and slot radiators with arbitrary geometric and electrophysical parameters presented in the monograph were obtained within the framework of the unified methodological approach to construct asymptotic solutions of integral equations on currents and their systems. This approach made it possible to study a number of new combined vibrator-slot structures. The research results reveal the possibilities of using such structures as basic elements in the creation of modern antenna-waveguide devices operating in the ranges from meter to millimeter wavelengths, with new technical characteristics and functional purpose. The book is intended for senior and postgraduate students and researchers working in the fields of radiophysics, radio engineering and antenna-feeder design. The book covers the following topics: • excitation of electromagnetic waves in volumes with coordinate boundaries;• general issues of the theory of thin impedance vibrators and narrow slots in a spatial-frequency representation;• solution of current equations for isolated vibrator and slot scatterers;• combined radiating vibrator-slot structures in rectangular waveguide;• T-junctions of rectangular waveguides with vibrator-slot structures in coupling areas;• waveguide radiation of the combined vibrator-slot structures;• combined vibrator-slot structures located on a perfectly conducting sphere;• combined vibrator-slot Radiators in antenna arrays;• ultrawideband vibrator-slot structures;
Each year a large number of first rate articles on the physics and technology of semiconductor devices, written by Soviet experts in the field, are published. However, due to the lack of exchange and personal contact, most of these, unfortunately, are neglected by many scientists from the United States, Japan as well as Western Europe. Consequently, many important developments in semiconductor physics are missed by the Western world.This book is a serious attempt to bridge the gap between the Soviet and Western scientific communities. Most of all, it is an effort towards facilitating the communication and sharing of knowledge amongst people from different parts of the world. Ultimately, the aim is to contribute towards the building of a better world for all ? one where the knowledge of advanced technology and scientific discoveries is used to improve the quality of life and not the pursuit of selfish mutually destructive behavior. For those in the field who wish to partake in this exchange of knowledge and as a gesture of support for their Soviet counterparts, the reading of this book provides the first step.
It seems there is no special need to comment on the term 'nanostructure' now, when one often meets the 'nano' words not only in scientific journals but even in newspapers. Moreover, today they are even to be heard in TV and radio programmes. In academic science, where the terms 'nanostructure' and 'nan otechnology' have been extremely popular since the early 1990s, they have been successfully extended to the sphere of economics and business, and now to politics. This is quite natural because nanostructures and nanotechnolo gies will surely serve as a basis for the most advanced and highest technology production in the nearest and probably also the remote future. Hence, the struggle to create and occupy its markets is already under way. In this respect, it is of great interest to review data on the dynamics of U. S. Federal Goverment expenditure for nanotechnology [1,2]. In the fiscal years 1997 and 2002, expenditure was approximately US$116 and US$ 697 million, respectively. In the fiscal year 2004, the President's request for US federal in vestment in nanoscale science, engineering and technology is about US$ 849 million [2]. The indicative budget allocated to the Thematic Priority enti tled 'Nanotechnologies and nanosciences, knowledge-based multifunctional materials and new production processes and devices' for the duration 2002- 2006 of the sixth EU Framework Programme for Research and Technological Development is EUR 1300 million [3].
This unique volume traces the behavior of the drug substance, starting from the initial pre-contact stage, and ending with the formation of the complex. Molecular recognition lies in the foundation of every life form and includes many mysteries. Currently, studies on this topic in pharmacology are limited to determining the properties of complexes of medicinal substances (drugs) with specific (complementary) biomolecules: receptors, enzymes, ion channels etc. The results present the mechanisms preventing drugs from such non-specific binding. This direction is very fruitful, although the phenomenon of molecular recognition is far wider. Features Presents the basics of thermodynamics and kinetics of complex formation between ligands and receptors Selected novel therapeutic concepts are tested and validated Provides a review of the pharmacophore approach and drug design methods By its nature, pharmacology is a multi-disciplinary science, hence, disciplinary areas include chemistry, biology and neuroscience Discusses hot topics including 3D structure determination techniques and in silico methods and neural networks The main theme of the book is the consideration of mechanisms created by nature to protect physiologically active substances from being stuck on nonspecific acceptors in the body. The book describes the materials that aid in the development of new medicinal substances. It is intended for researchers, as well as upper-level undergraduate and graduate students interested in the problems of molecular pharmacology and drug design.

This groundbreaking work features two essays written by the renowned mathematician Ilan Vardi. The first essay presents a thorough analysis of contrived problems suggested to “undesirable” applicants to the Department of Mathematics of Moscow University. His second essay gives an in-depth discussion of solutions to the Year 2000 International Mathematical Olympiad, with emphasis on the comparison of the olympiad problems to those given at the Moscow University entrance examinations.The second part of the book provides a historical background of a unique phenomenon in mathematics, which flourished in the 1970s-80s in the USSR. Specially designed math problems were used not to test students' ingenuity and creativity but, rather, as “killer problems,” to deny access to higher education to “undesirable” applicants. The focus of this part is the 1980 essay, “Intellectual Genocide”, written by B Kanevsky and V Senderov. It is being published for the first time. Also featured is a little-known page of the Soviet history, a rare example of the oppressed organizing to defend their dignity. This is the story of the so-called Jewish People's University, the inception of which is associated with Kanevsky, Senderov and Bella Subbotovskaya.
An urgent analysis of the battle between Russia and the West and an exposé of Putin’s Russia, by a former Kremlin insider. "I'm a fairly calm fellow; I don't usually get wound up about things. But I was, let's say, concerned when I tuned into the Moscow Echo radio station and heard that the Kremlin had put a price on my head. The announcement didn't quite say 'dead or alive'. But it came close..." —Mikhail Khodorkovsky, March 2021 Mikhail Khodorkovsky has seen behind the mask of Vladimir Putin. Once an oil tycoon and the richest man in Russia, Khodorkovsky spoke out against the corruption of Putin's regime—and was punished by the Kremlin, stripped of his entire wealth and jailed for over ten years. Now freed, working as a pro-democracy campaigner in enforced exile, Khodorkovsky brings us the insider's battle to save his country's soul. Offering an urgent analysis of what has gone wrong with Putin, The Russia Conundrum maps the country's rise and fall against Khodorkovsky's own journey, from Soviet youth to international oil executive, powerful insider to political dissident, and now a high-profile voice seeking to reconcile East and West. With unparalleled insight, written with Sunday Times bestselling author Martin Sixsmith, The Russia Conundrum exposes the desires and damning truths of Putin's "mafia clan," and provides an answer to the West on how it must challenge the Kremlin—in order to pave the way for a better future.
The structure of sedimentary basins of the Russian Arctic Seas is studied and illustrated by a number of maps, cross-sections and geophysical models. The calculated density models of the Earth crust illustrate the deep structure of the main blocks of the crust. Five major gas-condensate and gas fields are discovered here: three (Shtokman, Ludlov, Ledovoe) in the Barents and two (Leningrad and Rusanov) in the Kara Sea.Geological and geophysical characteristics of the Russian Arctic Sea sedimentary basins allow an estimation of their hydrocarbon potential by comparison with the known world analogues.Total potential resources of giant deposits of hydrocarbons in Russian Arctic Seas are estimated at 470 billion barrels of oil equivalent. The richest resources are the Kara Sea and Laptev Sea. Less rich is Barents Sea. The relatively smaller contribution to the overall estimation of the resources makes the resources of East-Siberian Sea and Chukchi Sea.Development the energy capacity of the continental shelf of Russia can play a stabilizing role in the dynamics of oil and gas production in the period 2010-2020. A key role in developing the capacity of the Arctic shelf oil and gas play is the innovative technology in exploration, production and management of the relevant investment projects. World offshore experience indicates that the combination of these factors is achieved through the formation of international firms and organizations. - Comprehensively assesses the potential oil and gas resources in sedimentary basins within the Russian sector of the Arctic Ocean - Describes the economic and legal challenges to the development of offshore fields in Russia - Explores possible ways and timing to maKe these hydrocarbon resources available to the global market

Electron Paramagnetic Resonance (EPR) spectroscopy - also sometimes termed Electron Spin Resonance spectroscopy - has manifold potential uses in biochemistry and medicine. The paramount importance of EPR spectroscopy applied to biological tissues and fluids is that it identifies the changes in redox processes that contribute to disease. EPR spectroscopy has come a long way from its original use to detect malignant tumors. For example, the development and later refinement of methods of low-temperature registration of biological tissues widened the scope of EPR spectroscopy. Innovations made possible by the introduction of spin labels, probes, and traps made EPR spectroscopy ever more applicable to biochemistry and medicine, to the point where in vivo studies are being carefully considered. This comprehensive book discusses spectra of many tissues and bodily fluids, and the quantitative nature of paramagnetic centers in both normal individuals and patients suffering from a variety of diseases. Special attention is given to the EPR examination of bio-molecules, such as enzymes, polypeptides, vitamins, lipids, hydrocarbons, etc., which play an essential role in human activity. This book will be of great interest to physicians specializing in many different areas. Similarly, biologists, biochemists, biophysicists, and chemists will find this book very useful. It has also been written so that it may be used as a textbook at graduate level.
