The outstanding theoretical physicist Arkady Benediktovich Migdal was one of the pioneers of theoretical nuclear physics in the Soviet Union, the founder of a major scientific school, a man of diverse gifts and irresistible personal charm. A. B. Migdal was born on March 11, 1911, in Lida (Belarus). In the 1920s his family moved to Leningrad. Migdal produced his first scientific work at age 17. He then enrolled at the physics department of the Leningrad State University (LSU), but studied there only a short while: arrested, he spent over two months under investigation, then was released (releases were still granted sometimes then). From 1931 to 1936, while working at the factory "Electrical Appliance," he produced several scientific works. At this time he managed to recover a place at the LSU extension division. After graduation in 1936 A. B. Migdal enrolled in graduate school at the Leningrad Physical-Technical Institute, where he formed his research interests and his own research style. His thesis adviser was M. P. Bronshtein. [Note: See footnote, p. 171.] Despite the briefness of this contact with Bronshtein - in 1937 Matvei Petrovich was arrested and executed - this bright, talented and deep person played a major role in Migdal's scientific development...

COGcollator: a web server for analysis of distant relationships between homologous protein families.
Dibrova, Daria V; Konovalov, Kirill A; Perekhvatov, Vadim V; Skulachev, Konstantin V; Mulkidjanian, Armen Y

The Clusters of Orthologous Groups (COGs) of proteins systematize evolutionary related proteins into specific groups with similar functions. However, the available databases do not provide means to assess the extent of similarity between the COGs. We intended to provide a method for identification and visualization of evolutionary relationships between the COGs, as well as a respective web server. Here we introduce the COGcollator, a web tool for identification of evolutionarily related COGs and their further analysis. We demonstrate the utility of this tool by identifying the COGs that contain distant homologs of (i) the catalytic subunit of bacterial rotary membrane ATP synthases and (ii) the DNA/RNA helicases of the superfamily 1. This article was reviewed by Drs. Igor N. Berezovsky, Igor Zhulin and Yuri Wolf.

To make a comparative morphometric analysis of the nuclei and nucleoli of tumor cells in lymphogranulomatosis (LGM), diffuse large B-cell lymphoma (DLBCL) and anaplastic large cell lymphoma (ALCL) for differential diagnosis of these lymphomas. Biopsy material (lymph node biopsies) was frozen in hexane, fixed and stained, then microscopic pictures were made. Mean area of tumor cell nuclei in LGM was 97.25 +/- 68.77 mcm2, in DLBCL and ALCL--55.89 +/- 20.13 mcm2 and 70.31 +/- 34.64 mcm2, respectively. The area differences were significant (p < 0.001). Hodgkin's and Berezovsky-Rid-Sternberg cell bucleoli area was the largest (11.44 +/- 7.83 mcm2). The nucleoli of the former are larger than those of the latter. Mean area of the nucleoli in DLBCL was 3.05 +/- 1.58, in ALCL--5.53 +/- 4.94 mcm2. The differences are significant (p < 0.001). Nucleoli in Hodgkin 's cells are significantly larger than those in the tumor cells in ALCL and DLBCL and the nucleoli with the area more than 12 mcm2 can be used in differential diagnosis between LGM and DLBCL but not between LGM and ALCL.

We report on an exceedingly rare lesion of the thyroid probably of a branchial cleft origin, which was not published in the world literature before. A 58-year-old woman underwent a total thyroidectomy for bilateral goiter. Grossly, there was one yellowish nodule sized 15 mm in the largest dimension found in the right lobe. Microscopically, the thyroid parenchyma showed signs of Hashimoto thyroiditis. The nodule in the right lobe was composed of a part of solid cell nests appearance, another part resembling a branchial cleft cyst, and a part resembling Warthin tumor. This lesion may belong to the histogenetically similar group of entities in the head and neck region which are derived from branchial cleft derivatives and which, under the inflammatory influence, have the ability to a cystic dilatation and proliferation of the epithelial component. The epithelium can afterwards become papillary and may undergo oncocytic transformation, thus gaining features that impart the resemblance of a Warthin tumor. Club members generally agreed with a submitted diagnosis of benign Warthin tumor of the thyroid.

Real-time ab initio simulations of excited-state dynamics in nanostructures
NASA Astrophysics Data System (ADS)
Tomanek, David
2007-03-01
Combining time-dependent ab initio density functional calculations for electrons with molecular dynamics simulations for ions, we investigate the effect of excited-state dynamics in nanostructures. In carbon nanotubes, we find electronic excitations to last for a large fraction of a picosecond. The de-excitation process is dominated by coupling to other electronic degrees of freedom during the first few hundred femtoseconds. Later, the de-excitation process becomes dominated by coupling to ionic motion. The onset point and damping rate in that regime change with initial ion velocities, a manifestation of temperature dependent electron-phonon coupling. Considering the fact that the force field in the electronically excited state differs significantly from the ground state, as reflected in the Franck-Condon effect, atomic bonds can easily be broken or restored during the relatively long lifetime of electronic excitations. This effect can be utilized in a ``photo-surgery" of nanotubes, causing structural self-healing at vacancy sites or selective de-oxidation processes induced by photo-absorption. Also, electronic excitations are a key ingredient for the understanding of sputtering processes in nanostructures, induced by energetic collisions with ions.

Towards a complete Fermi surface in underdoped high Tc superconductors
NASA Astrophysics Data System (ADS)
Harrison, Neil
The discovery of magnetic quantum oscillations in underdoped high Tc superconductors raised many questions, and initiated a quest to understand the origin of the Fermi surface the like of which had not been seen since the very first discovery of quantum oscillations in elemental bismuth. While studies of the Fermi surface of materials are today mostly assisted by computer codes for calculating the electronic band structure, this was not the case in the underdoped high Tc materials. The Fermi surface was shown to reconstructed into small pockets, yet there was no hint of a viable order parameter. Crucial clues to understanding the origin of the Fermi surface were provided by the small value of the observed Fermi surface cross-section, the negative Hall coefficient and the small electronic heat capacity at high magnetic fields. We also know that the magnetic fields were likely to be too weak to destroy the pseudogap and that vortex pinning effects could be seen to persist to high magnetic fields at low temperatures. I will show that the Fermi surface that appears to fit best with the experimental observations is a small electron pocket formed by connecting the nodal `Fermi arcs' seen in photoemission experiments, corresponding to a density-wave state with two different orthogonal ordering vectors. The existence of such order has subsequently been detected by x-ray scattering experiments, thereby strengthening the case for charge ordering being responsible for reconstructing the Fermi surface. I will discuss new efforts to understand the relationship between the charge ordering and the pseudogap state, discussing the fate of the quasiparticles in the antinodal region and the dimensionality of the Fermi surface.

we have assembled a representative set of papers written by experts with diverse scientific backgrounds, each offering a unique viewpoint on using computational and physics methods to study biological systems at different levels of organization. We start with studies that aim to decipher the mechanisms of molecular recognition using biophysics methods and then expand our scale, concluding the issue with studies of interaction networks at cellular and population levels. Biomolecules interact with each other in a highly specific manner and selectively recognize their partners among hundreds of thousands of other molecules. As the paper by Zhang et al points out, this recognition process should be fast and guided by long-range electrostatic forces that select and bring the interacting partners together. The authors show that the increase of salt concentration leads to destabilization of protein complexes, suggesting an optimization of the charge-charge interactions across the protein binding interfaces. The following paper by Berezovsky further explores the balance of different interactions in protein complexes and uses physical concepts to explain the entire spectrum of protein structural classes, from intrinsically disordered to hyperthermostable proteins. The author describes highly unstructured viral proteins at one end of the spectrum and discusses the balance of stabilizing interactions in protein complexes from thermophilic organisms at the other. Recently accumulated evidence has indicated that native proteins do not necessarily require a unique structure to be biologically active, and in some cases structural disorder or intrinsic flexibility can be a prerequisite for their function. From the physical point of view, these disordered/flexible proteins exist in dynamic equilibrium between different conformational states, some of which could be selected upon binding to another partner. Such a property allows disordered proteins to achieve specific binding and at

many ways a monument to human progress. And this ceremony is a testament to the truth that old adversaries can forge new partnerships. I could not help but be struck the other day by the words of Arkady Brish, who helped build the Soviet Union’s first atom bomb. At the age of 92, having lived to see the horrors of a World War and the divisions of a Cold War, he said, We hope humanity will reach the moment when there is no need for nuclear weapons, when there is peace and calm in the world. It’s easy to dismiss those voices. But doing so risks repeating the horrors of the past, while ignoring the history of human progress. The pursuit of peace and calm and cooperation among nations is the work of both leaders and peoples in the 21st century. For we must be as persistent and passionate in our pursuit of progress as any who would stand in our way. Once again, President Medvedev, thank you for your extraordinary leadership.« less
