  2. PREFACE: Alexei Zamolodchikov Alexei Zamolodchikov (United States)

    Bazhanov, V.; Belavin, A.; Pugai, Y.; Tsfasman, M.; Zamolodchikov, A.


    Alexei Zamolodchikov, a prominent theoretical physicist, passed away on the night of 18 October 2007. His untimely death is a great loss for science, and for everybody who knew and loved him. The heartbreak and pain of his departure cannot be rendered in words; it is also difficult to describe in a brief note the remarkable contributions of Alexei Zamolodchikov to different areas of theoretical physics and to depict the grace of his personality. Alexei Zamolodchikov loved Russia, and felt acutely for the plight of our country. His last position was at the Poncelet Laboratory in Moscow. This year he was going to give a course for undergraduate and graduate students at the Independent University of Moscow. The first lecture was to be given on 10 October 2008. The principal scientific accomplishments of A Zamolodchikov are in the area of quantum field theory. These are works on integrable field theory and the factorized scattering theory; basic results on conformal field theory; a pioneering and fundamental contribution to two-dimensional Liouville gravity and the related non-critical string theory. A Zamolodchikov's ideas were always original and deep. Here is a brief list of some of them: •The creation of the theory of factorized S-matrices. •The discovery of recursive relations for conformal blocks, the key objects of conformal field theory. •Understanding the nature of operator product expansions in conformal perturbation theory. •The discovery of the thermodynamic Bethe anzatz in quantum field theories. •Establishing the exact relation between different scales in integrable field theories. •Construction of the conformal bootstrap in Liouville field theory, including the theory with boundary and the one on the pseudo-sphere. •The discovery of higher equations in Liouville field theory. •The explicit formula for the 4-point function in minimal string theory. A Zamolodchikov died at the high point of his career, as his talent flourished, in the midst

  4. IN MEMORIAM: In Memoriam: Alexander A Golovin and Alexei M Oparin In Memoriam: Alexander A Golovin and Alexei M Oparin (United States)


    2008 In Memoriam of Alexei M Oparin (1964-2008) Alexei (Lesha) Oparin passed away on 4 December 2008. Alexei graduated from the Moscow Institute for Physics and Technology in 1987, received his PhD at Landau Institute for Theoretical Physics in 1996, and, after training at the Max Plank Institute for Quantum Optics in Germany, worked at the Institute for Computer Aided Design of the Russian Academy of Sciences, where he became the chair of the Department of Numerical Methods and Turbulence. He built the Department so that in a short period of time it grew from 3 to 15 scientists and became one of the leading centers in Russia in numerical modeling of turbulent flows. In Lesha's works, his talent was combined with the academic depth and the breadth of his scientific interests. Lesha's scientific heritage covers many fields of computational physics, including ignition and burn of deuterium-tritium fuel for the inertial confinement fusion; the flow of matter induced by ultra-short laser impulse; the exact expansion law for the Richtmyer-Meshkov turbulent mixing zone; growth-rate of the Rayleigh-Taylor instability for nuclear fusion; temperature and entropy separation in the Ranque-Hilsch tube; tornado origination from mezzo-cycle; turbulent nature of Jupiter spot; secondary vortex of the gas centrifuge; cascade of instabilities in Couette flow. One of these works is published in this issue. What make it necessary to get the flow rolled up in zones of high gradients? Why do we have to restrict ourselves to the Reynolds number only, rather than to follow the experiment and get more parameters for stability? Where are the nuts and bolts of the turbulence? Many of these investigations were initiated and led by Lesha, and were based on his ability to identify the essence of the challenging problems and to formulate and address the right questions with mathematical elegance and physical intuition. A lot of work has been done by Lesha. Other problems remain to be solved, to our

    Full Text Available The present paper represents the review for the volume Alexei Marco. The destiny of a jeweler from Moldova, by Liliana Condraticova, published at Lumen Publishing House, a volume about the monographic study of an artist jeweler from Moldova. The work comes as a novelty element in the cultural context of Moldova. The lack of studies regarding the life and work of the masters of jewelry manufacturing, determined the author to develop a work in order to provide relevant, comprehensive information, in terms of the artistic creation of the most famous jeweler in Moldova – Alexei Marco. The study uses monographic method, a method used particularly in empirical research, which involves direct observation of territorial social unit without the use of sampling and without manipulating variables. The social reality investigated is approached in all its manifestations.

    Matricon, Jean


    Among the most peculiar of matter¡¦s behaviors is superconductivity„oelectric current without resistance. Since the 1986 discovery that superconductivity is possible at temperatures well above absolute zero, research into practical applications has flourished. The Cold Wars tells the history of superconductivity, providing perspective on the development of the field and its relationship with the rest of physics. Superconductivity offers an excellent example of the evolution of physics in the twentieth century: the science itself, its foundations, and its social context. The authors also introduce the reader to the fascinating scientific personalities, including 2003 Nobel Prize winners Alexei Alexeievich Abrikosov and Vitali Ginzburg, and political struggles behind this research.

Understandably, their readers need to keep accessing these books at all cost and gather into groups around book-bearers, or, as they're called, librarians. Alexei, until now a loser, comes to collect an uncle's inheritance and unexpectedly becomes a librarian. He tells his extraordinary, unbelievable story.

    Directory of Open Access Journals (Sweden)

    Elena E. Sokolova


    Full Text Available This essay is aimed at considering the possibility itself of "metacomprehension" of the mental reality so cherished by Lev Vygotsky from the positions of cultural and activity psychology. It is demonstrated that the program Vygostky outlined for creating the new "general psychology" involves the use of dialectical logic (as opposed to the contemporary projects of "integrative psychology" based on the "and - and" logic. Applied in a creative way to the problem of nature of mental reality, the dialectical logic let the adherents of Alexei Leontiev school draw the conclusion that activity can be regarded as a substance of mind and that, conse¬quently, the mind can be regarded as a "functional organ" of activity. Such an inter¬pretation of the mental reality makes it possible to resolve a number of theoretical and practical psychological problems anew.

    The 2003 Nobel Prizes in Physics and in Physiology or Medicine, announced last week, both have connections with particle physics and CERN. Alexei Abrikosov, Vitaly Ginzburg and Anthony Leggett have received the prize in physics for their "pioneering contributions to the theory of superconductors and superfluids". The most important superconducting materials technically have proved to be those known as type II superconductors, which allow superconductivity and magnetism to exist at the same time and remain superconductive in high magnetic fields. The coils for the superconducting magnets in CERN's Large Hadron Collider are made from niobium-titanium alloy - a type II superconductor. The LHC will operate thanks to magnets made of type II superconductors. Here, superconducting cables for the LHC are on display during a VIP visit.Abrikosov, who is now at the Argonne National Laboratory, was working at the Kapitsa Institute for Physical Problems in his native Moscow when he succeeded in formula...

The author shows two significant differences in present-day stressing that linguistics of the XIX century was closer to the present-day political science? As he believes. The first difference includes monism of political science approach, since the book reveals monistic scale from totalitarianism to democracy, while linguistic has abandoned the monistic view on typology. The second difference is the value-addedness of the political science approach. The value-free norm in linguistics presupposes setting up of a single standard for all speakers in order to reach full mutual understanding. In political science subjective criteria are decisive for evaluation. The article gives examples from the book to prove that political science, compared to linguistics, is not aimed at overcoming contradictions, distinguishing between the terms, avoiding unproved statements and subjective evaluations.

  20. [Neurosciences and the ravings of the Soviet era. Spanish Republican physicians, a set of privileged witnesses]. (United States)

    Marco-Igual, Miguel


    This study analyses the links between the Russian and Soviet neurosciences and their Spanish counterpart, especially with regard to the experiences of the Spanish Republican physicians exiled in the USSR. The Russian neurosciences, which date back to the second half of the 19th century, followed a path that ran parallel to the discipline throughout the rest of Europe and finally displayed signs of being influenced by the German and French schools. Important figures include Alexei Kojevnikov and Vladimir Bekhterev in neurology, Sergei Korsakov in psychiatry, Ivan Pavlov and his disciple Piotr Anojin in neurophysiology, Lev Vygotsky and Alexander Luria in neuropsychology, and Nikolai Burdenko in neurosurgery. When the Bolsheviks came to power, they brought with them a progressive conception of health care, which was modified during the Stalinist era to serve political interests, above all in the case of psychiatry. During the first third of the 20th century, Spanish scientists became interested in Pavlov's reflexology and the Soviets took a similar interest in Spanish histology. Among the 4500 Spanish Republicans who emigrated to the USSR because of the Spanish Civil War, there were several dozen physicians who were privileged witnesses of the madness that shook the science and the health care of that period. Relevant names worth citing here from the field of the neurosciences include Juan Planelles and Ramon Alvarez-Buylla in neurophysiology, Federico Pascual and Florencio Villa Landa in psychiatry, Angel Escobio and Maria Perez in neurology, Julian Fuster in neurosurgery and Manuel Arce in neuroimaging.

  1. Russia's imperial blood: was Rasputin not the healer of legend? (United States)

    Kendrick, John M L


    The only son of Russia's last Tsar, a great-grandson of Queen Victoria, continues to be used as the favorite example of the X-linked inheritance of hemophilia, in spite of the fact that this popular historical diathesis has never been confirmed by any form of modern medical laboratory testing. Certain to be controversial, a new study of the symptoms that were witnessed by those who were closest to the teenaged Russian heir now raises the possibility that his blood disorder might well have been something other than hemophilia. The key to discovering Tsarevich Alexei's true diagnosis is found in those now legendary allegations that the infamous "Mad Monk", Grigory Rasputin, had possessed a power of healing that was somehow responsible for the young boy's mysterious history of spontaneous recoveries. If we are to accept the popular diagnosis of history and call it a clotting factor deficiency, then the boy's now famous sudden recoveries will remain a complete mystery. The so-called "Mad Monk" Rasputin, as a direct result of the revolutionary propaganda of the time, is then overblown into a larger-than-life legend. If, however, we are to change the diagnosis and call it a platelet disorder, then the air is let out of the legend, and Rasputin is revealed to have been nothing more than a very ordinary middle-aged Siberian hippie who did not possess any healing powers at all.

  3. Noise-induced transitions and resonant effects in nonlinear systems (United States)

    Zaikin, Alexei


    Our every-day experience is connected with different acoustical noise or music. Usually noise plays the role of nuisance in any communication and destroys any order in a system. Similar optical effects are known: strong snowing or raining decreases quality of a vision. In contrast to these situations noisy stimuli can also play a positive constructive role, e.g. a driver can be more concentrated in a presence of quiet music. Transmission processes in neural systems are of especial interest from this point of view: excitation or information will be transmitted only in the case if a signal overcomes a threshold. Dr. Alexei Zaikin from the Potsdam University studies noise-induced phenomena in nonlinear systems from a theoretical point of view. Especially he is interested in the processes, in which noise influences the behaviour of a system twice: if the intensity of noise is over a threshold, it induces some regular structure that will be synchronized with the behaviour of neighbour elements. To obtain such a system with a threshold one needs one more noise source. Dr. Zaikin has analyzed further examples of such doubly stochastic effects and developed a concept of these new phenomena. These theoretical findings are important, because such processes can play a crucial role in neurophysics, technical communication devices and living sciences. Unsere alltägliche Erfahrung ist mit verschiedenen akustischen Einfluessen wie Lärm, aber auch Musik verbunden. Jeder weiss, wie Lärm stören kann und Kommunikation behindert oder gar unterbindet. Ähnliche optische Effekte sind bekannt: starkes Schneetreiben oder Regengüsse verschlechtern die Sicht und lassen uns Umrisse nur noch schemenhaft erkennen. Jedoch koennen ähnliche Stimuli auch sehr positive Auswirkungen haben: Autofahrer fahren bei leiser Musik konzentrierter -- die Behauptung von Schulkindern, nur bei dröhnenden Bässen die Mathehausaufgaben richtig rechnen zu können, ist allerdings nicht wissenschaftlich

  6. Mystery solved: the identification of the two missing Romanov children using DNA analysis.

    Directory of Open Access Journals (Sweden)

    Michael D Coble

    Full Text Available One of the greatest mysteries for most of the twentieth century was the fate of the Romanov family, the last Russian monarchy. Following the abdication of Tsar Nicholas II, he and his wife, Alexandra, and their five children were eventually exiled to the city of Yekaterinburg. The family, along with four loyal members of their staff, was held captive by members of the Ural Soviet. According to historical reports, in the early morning hours of July 17, 1918 the entire family along with four loyal members of their staff was executed by a firing squad. After a failed attempt to dispose of the remains in an abandoned mine shaft, the bodies were transported to an open field only a few kilometers from the mine shaft. Nine members of the group were buried in one mass grave while two of the children were buried in a separate grave. With the official discovery of the larger mass grave in 1991, and subsequent DNA testing to confirm the identities of the Tsar, the Tsarina, and three of their daughters--doubt persisted that these remains were in fact those of the Romanov family. In the summer of 2007, a group of amateur archeologists discovered a collection of remains from the second grave approximately 70 meters from the larger grave. We report forensic DNA testing on the remains discovered in 2007 using mitochondrial DNA (mtDNA, autosomal STR, and Y-STR testing. Combined with additional DNA testing of material from the 1991 grave, we have virtually irrefutable evidence that the two individuals recovered from the 2007 grave are the two missing children of the Romanov family: the Tsarevich Alexei and one of his sisters.

  7. Academic Biography in the Context of the Anti-Formalist Campaign of the 1930s

    Directory of Open Access Journals (Sweden)

    Yelena N. Penskaya


    Full Text Available The paper is focused around two biographical themes. Theme one is history of demolishing Leningrad school of dramatic theory developed in the State Institute of History of Art (GIII in the 1920s. In 1931, the GIII was closed by a Sovnarkom resolution and transformed into Len- ingrad division of the State Academy of Art Studies (LOGAIS established by the same resolu- tion. Theme two is description of the ‘academic traumatism’, traumatic behavior and its bio- graphical effects caused by destruction of a whole scientific trend during the anti-formalism campaign of the early 1930s. Based on archival documents (from the Russian State Archive of Literature and Art, shorthand notes and reports on discussions of the 1930s, we analyze behav- ioral tactics of initiators, participants and victims of the longstanding stigmatization and catalog absolutory, denunciative and repentant narratives. In particular, this paper analyzes the un- published letter to the editors of Rabochiy i Teatr journal written by Alexander Slonimsky, one of the key players in development and obliteration of dramatic theory associated primarily with Alexei Gvozdev’s group and with transformation and dissolution of the leading humanities in- stitutes. The text of the letter appears to be engrained in the complicated mosaic of measures aimed to discredit Meyerhold’s theater practice and Gvozdev as the leader of the scientific school. Deliberate misinterpretation and corruption of self-descriptions along with reconstruc- tion of biographies are some of the most crucial factors that affected reception of cultural pro- jects and their creators in the 1930s and later.

  8. Severnaya Zemlya – geography with history at the turn of times

    V. M. Kotlyakov


    Full Text Available 100 years ago, in 1913, there was committed last geographical discovery of world importance in the Russian Arctic. Icebreaking transports «Taimyr» and «Vaygach» discovered and photographed the eastern and southern shores of the unknown land separating the Kara and Laptev seas. Boris Vilkitski Strait was opened by the north of Taimyr Peninsula as well as two small islands. Coast of the newly discovered lands received a legal name «Emperor Nicholas II Land», one of the islands was named in honor of the heir of the monarch – Tsarevich Alexei. After 1924 there was introduced the common name for a geographic feature – «Severnaya Zemlya» (North Land. Since 1926, the name «Emperor Nicholas II Land» was removed for political reasons. North shore land remained anonymous until now. In world practice (on the map of Greenland, Antarctica the description of shores by the names of monarchs shores coexist with the common name of the main geographical object. In 1930–1932 a full examination of Severnaya Zemlya was carried out by Ushakov–Urvantsev expedition. There was found that an archipelago consists of several islands. «Not-simultaneous» shore opening and land surveying all over the archipelago led to divergent assessments of the events and facts.Preservation of historic names as a cultural and historical heritage, the inadmissibility of the historical names abolition are supported by the acting Russian Federation Law on the names of geographic features. The authors emphasize the need to return to the historical names with the application of national legislation and with justification of solutions Russian Arctic toponymy problems from international practices.

  9. Building Baluchitherium and Indricotherium: imperial and international networks in early-twentieth century paleontology. (United States)

    Manias, Chris


    Over the first decades of the twentieth century, the fragmentary remains of a huge prehistoric ungulate were unearthed in scientific expeditions in India, Turkestan and Mongolia. Following channels of formal and informal empire, these were transported to collections in Britain, Russia and the United States. While striking and of immense size, the bones proved extremely difficult to interpret. Alternately naming the creature Paraceratherium, Baluchitherium and Indricotherium, paleontologists Clive Forster-Cooper, Alexei Borissiak and Henry Fairfield Osborn struggled over the reconstruction of this gigantic fossil mammal. However, despite these problems, shared work on the creature served as a focus for collaboration and exchange rather than rivalry between these three scientific communities. Not only did the initial interpretation and analysis depend on pre-existing connections between British and American paleontological institutions, but the need for comparative material, recognition and contacts brought British and American scholars into communication and exchange with their counterparts in the Soviet Union. This article examines these processes. It first uses these excavations as a comparative case-study of different manifestations of colonial science in this period, examining how scholars in the Britain, the Russian Empire and the United States used formal and informal colonial links to Asia to pursue new research. It then moves to examine how the common problem of reconstructing this giant animal drew metropolitan scientific communities together, at least for a time. The construction of the Baluchitherium and Indricotherium illustrates the drives to expand research both imperially and internationally in the early-twentieth century, but also the continual problems in resources, institutionalization, transport and communication that could run up against scientific work.

  14. Fault-tolerance in Two-dimensional Topological Systems (United States)

    Anderson, Jonas T.

    This thesis is a collection of ideas with the general goal of building, at least in the abstract, a local fault-tolerant quantum computer. The connection between quantum information and topology has proven to be an active area of research in several fields. The introduction of the toric code by Alexei Kitaev demonstrated the usefulness of topology for quantum memory and quantum computation. Many quantum codes used for quantum memory are modeled by spin systems on a lattice, with operators that extract syndrome information placed on vertices or faces of the lattice. It is natural to wonder whether the useful codes in such systems can be classified. This thesis presents work that leverages ideas from topology and graph theory to explore the space of such codes. Homological stabilizer codes are introduced and it is shown that, under a set of reasonable assumptions, any qubit homological stabilizer code is equivalent to either a toric code or a color code. Additionally, the toric code and the color code correspond to distinct classes of graphs. Many systems have been proposed as candidate quantum computers. It is very desirable to design quantum computing architectures with two-dimensional layouts and low complexity in parity-checking circuitry. Kitaev's surface codes provided the first example of codes satisfying this property. They provided a new route to fault tolerance with more modest overheads and thresholds approaching 1%. The recently discovered color codes share many properties with the surface codes, such as the ability to perform syndrome extraction locally in two dimensions. Some families of color codes admit a transversal implementation of the entire Clifford group. This work investigates color codes on the 4.8.8 lattice known as triangular codes. I develop a fault-tolerant error-correction strategy for these codes in which repeated syndrome measurements on this lattice generate a three-dimensional space-time combinatorial structure. I then develop an

    Institute of Scientific and Technical Information of China (English)

    王晓芳; 姜云瀚; 孙军


    The key role of mitochondria in cell death has been widely accepted, but it remains unclear on how other organelles influence mitochondria to initiate cell death. Recently, Alexei et al. Proposed a theory of lysosomal-mitochondrial axis that explained the mechanism of lysosome- mitochondria interaction based on latest studies in lysosomal functions. Apoptotic factors may permeablize the lysosomal membrane, then through iron-dependent, lipofuscin-related, Bcl-2 family-dependent, or Rho/ROCK-JNK pathways cause in the permeability of mitochondrial membrane and initiate cell death. On the other hand, mitochondrial membrane permeabilization can also permeablize the lysosomal membrane through the ROS-dependent and Bcl-2 family- dependent ways and promotes cell death. The theory of " lysosomal-mitochondrial axis" was lately being used to explain the pathogenesis of nonalcoholic fatty liver disease and the lysosomal storage diseases. This review introduces the "lysosomal-mitochondrial axis" theory and discusses it implication in disease conditions.%线粒体在细胞死亡中占有中心地位,但其他细胞器影响线粒体启动细胞死亡的机制仍不十分明确.近几年来,随着对溶酶体功能的不断了解,Alexei等提出了溶酶体线粒体轴理论.这一理论阐述了溶酶体与线粒体的相互作用,并最终导致细胞死亡的机理.各种致凋亡因素作用于溶酶体,导致溶酶体膜通透性改变.溶酶体膜通透性改变能通过铁依赖的方式、脂褐素相关的方式、Bcl-2家族依赖的方式和Rho/ROCK途径-JNK信号通路的方式影响线粒体,造成线粒体膜通透性改变,进而启动细胞死亡.而线粒体膜通透性改变能通过ROS依赖的方式和Bcl-2家族依赖的方式引起溶酶体通透性改变,最终导致细胞死亡.溶酶体线粒体轴理论还能用于解释非酒精性脂肪肝和溶酶体贮积症的发病机制.本文将对溶酶体线粒体轴理论及其与疾病的关系两方面进行阐述.

    Mossbauer effect in physics and chemistry, in SANS studies of polyelectrolytes, small molecules, fractals, metallic glasses, macromolecules, polymers, etc., were recognized by a number of awards including the State Prize of the Russian Federation in 2000. The scientific program of the workshop focused on fundamental and methodical research at the YuMO spectrometer and developments of the SANS instrument at the modernized IBR-2M reactor. We recall that the acronym YuMO of the small-angle neutron scattering spectrometer (MURN), was given in honor of Yu M Ostanevich. One of the most important objectives of this user meeting was to discuss the further development possibilities of the YuMO spectrometer with experts, in the frame of a SANS YuMO Round Table, taking into account the specific performance of the modernized YuMO SANS instrument, and the scientific and technical requests of the instrument's users. Highlights on modern achievements in nanoscience, polymers and biology were other significant goals of the meeting. The plenary invited talks were presented by leading scientists in small-angle neutron scattering and soft condensed matter, including members of the Russian Academy of Sciences: Prof. Heinrich Stuhrmann, Prof. Alexei Khokhlov, Prof. Jose Teixeira, Prof. Alexander Ozerin, Prof. Albrecht Wiedenmann, etc. There were 27 oral talks given and 32 posters presented by 92 participants from 12 countries: Czech Republic, Egypt, France, Germany, Hungary, Moldova, Mongolia, Poland, Romania, Russian Federation, Slovak Republic, and Ukraine. The workshop was organized with the financial support of the Frank Laboratory of Neutron Physics (Joint Institute for Nuclear Research), Horia Hulubei National Institute of Physics and Nuclear Engineering - IFIN HH (Romania), Institute of Macromolecular Chemistry AS CR (Czech Republic), and Comenius University (Slovakia).

    experimental situation, i.e. to keep an eye on the future experiments that are planned to gather observational data on the cosmological parameters with unprecedented accuracy. Undoubtedly, some balanced phenomenology ingredient in a field like this is not only highly desirable, but actually indispensable to enable researchers to assess by themselves during the conference the real impact of the theoretical ideas versus experiments and observations, and vice versa. IRGAC 2006 in Barcelona was a follow-up to the first conference held in Ouro Preto, Brazil, in 2003 (under the slightly different acronym of IRGA 2003) [1]. The present, and more complete, name for this series (note the ending 'C') intends to stress the cosmology component of the meeting, and it is intended to stay in future editions. In this respect it is worth emphasizing that 2006 represented the 25th anniversary of the formulation of the inflationary paradigm, which nowadays appears as a theoretical conception perfectly compatible with, if not the most likely explanation for, the spatial flatness of our Universe as measured by the CMB data. This 25th anniversary was obviously a unique opportunity to accentuate and enhance the cosmology background of IRGAC 2006: see the full scientific program at As the chairman organizer of the conference, I was particularly interested to count, on this very special occasion, on the participation of the three outstanding cosmologists who first proposed the idea of inflation: Alan Guth, Andrei Linde and Alexei Starobinsky. I am very grateful to the three of them for being so positive in accepting my invitation to participate. I am especially grateful to Alan Guth for his early interest in our conference, expressed some two years before it took place. Needless to say, I am pleased to extend these thanks to the rest of the speakers and participants, without whom this conference would not have attained the high degree of scientific
