The role of beamstrahlung in high-energy e+e- storage-ring colliders (SRCs) is examined. Particle loss due to the emission of single energetic beamstrahlung photons is shown to impose a fundamental limit on SRC luminosities at energies 2E0 140 GeV for head-on collisions and 2E0 40 GeV for crab-waist collisions. With beamstrahlung taken into account, we explore the viability of SRCs in the 2E0=240-500 GeV range, which is of interest in the precision study of the Higgs boson. At 2E0=240 GeV, SRCs are found to be competitive with linear colliders; however, at 2E0=400-500 GeV, the attainable SRC luminosity would be a factor 15-25 smaller than desired. © 2013 American Physical Society.

In the last two decades, considerable efforts were invested in the search for synthetic iron and manganese catalysts with nonporphyrinic ligands, mimicking metalloenzymes in the oxygenation at CH and CC bonds of organic molecules. In many cases, the detailed knowledge of intimate reaction mechanisms and of the nature of active sites was critical for the rational design of biomimetic catalysts with predictable reactivities. This review discusses the up-to-date mechanistic landscape of non-heme iron and manganese catalyzed oxidations of olefinic groups and aliphatic CH groups with H2O2. © 2014.

The theory of inhomogeneous superfluid turbulence is developed on the basis of kinetics of merging and splitting vortex loops. Vortex loops composing the vortex tangle can move as a whole with some drift velocity depending on their structure and length. The flux of length, energy, momentum, etc., executed by the moving vortex loops takes place. The situation here is exactly the same as in usual classical kinetic theory, with the difference being that the "carriers" of various physical quantities are not the point particles but extended objects (vortex loops), which possess an infinite number of degrees of freedom, with highly involved dynamics. We suggest to complete our investigation, based on the supposition that vortex loops have a Brownian structure, with the only degree of freedom being, lengths of loops l. This concept allows us to study the dynamics of the vortex tangle on the basis of the kinetic equation for the distribution function n (l,t) -the density of a loop in the space of their lengths. Imposing the coordinate dependence on the distribution function n (l,r,t) and modifying the "kinetic" equation with regard to an inhomogeneous situation, we are able to investigate various problems on the transport processes in superfluid turbulence. In this paper, we evaluate the flux of the vortex line density L (x,t) due to the gradient of this quantity. The corresponding evolution of quantity L (x,t) obeys the diffusion type equation, as it can be expected from dimensional analysis. The diffusion coefficient is arrived at from calculation of the (size-dependent) free path and drift velocity of the vortex loops, and takes the value 2.2κ, which exceeds approximately 20-fold the value obtained in early numerical simulation. We discuss the probable reason for this large discrepancy. We use the diffusion equation to describe the decay of the vortex tangle at a very low temperature. Comparison with recent experiments on decay of the superfluid turbulence is presented. © 2010 The American Physical Society.

Maternally inherited microorganisms can influence the mtDNA pattern of variation in hosts. This influence is driven by selection among symbionts and can cause the frequency of mitochondrial variants in the population to eventually increase or decrease. Wolbachia infection is common and widespread in Drosophila melanogaster populations. We compared genetic variability of D. melanogaster mitotypes with Wolbachia genotypes among isofemale lines associated with different geographic locations and time intervals to study coevolution of the mtDNA and Wolbachia. Phylogenetic analysis of D. melanogaster mtDNA revealed two clades diverged in Africa, each associated with one of the two Wolbachia genotype groups. No evidence of horizontal transmission of Wolbachia between maternal lineages has been found. All the mtDNA variants that occur in infected isofemale lines are found in uninfected isofemale lines and vice versa, which is indicative of a recent loss of infection from some maternal fly lineages and confirms a significant role of Wolbachia in the D. melanogaster mtDNA pattern of variation. Finally, we present a comparative analysis of biogeographic distribution of D. melanogaster mitotypes all over the world. © 2013 Yury Ilinsky.

The general scope, dealing with techniques and Arrhenius parameters, influence of the C-centered radical structure on recombination, re-formation, or cross-coupling rate constant for the reaction between an alkyl radical and a nitroxide, influence of the nitroxide structure on recombination, re-formation, or cross-coupling rate constant for the reaction between an alkyl radical and a nitroxide, miscellaneous, calculations and pathway for the recombination reaction are reviewed. In the same period, NMP was discovered and promoted. Quickly, it appeared that the cross-coupling and HAT reactions were important for the fate of the NMP. On the other hand, organic chemists use more and more alkoxyamines as tools for the total synthesis of natural products, and the success of such applications relies on the values of recombination, re-formation, or cross-coupling rate constant for the reaction between an alkyl radical and a nitroxide.

A comprehensive collection of wheat aneuploids, whole chromosome substitutions (both intervarietal and interspecific) and wheat-alien addition lines, along with various introgression and near-isogenic lines, has been created over a period of years, primarily to provide the means of localizing the genes underpinning traits and to introduce novel genes into the bread wheat genome. For a time, interest in this class of genetic material was on the wane, but more recently it has revived in the context, for example, of localizing DNA-based markers, designing chromosome-specific bacterial artificial chromosome libraries, and establishing functional differences between alleles and homoeoalleles. Here, a brief review is provided of recent applications of precise genetic stocks in the field of molecular genetics, functional genetics and genomics of the Triticeae species. © 2014 Springer Science+Business Media Dordrecht.

On May 8, 1980, the World Health Assembly at its 33rd session solemnly declared that the world and all its peoples had won freedom from smallpox and recommended ceasing the vaccination of the population against smallpox. Currently, a larger part of the world population has no immunity not only against smallpox but also against other zoonotic orthopoxvirus infections. Recently, recorded outbreaks of orthopoxvirus diseases not only of domestic animals but also of humans have become more frequent. All this indicates a new situation in the ecology and evolution of zoonotic orthopoxviruses. Analysis of state-of-the-art data on the phylogenetic relationships, ecology, and host range of orthopoxviruses-etiological agents of smallpox (variola virus, VARV), monkeypox (MPXV), cowpox (CPXV), vaccinia (VACV), and camelpox (CMLV)-as well as the patterns of their evolution suggests that a VARV-like virus could emerge in the course of natural evolution of modern zoonotic orthopoxviruses. Thus, there is an insistent need for organization of the international control over the outbreaks of zoonotic orthopoxvirus infections in various countries to provide a rapid response and prevent them from developing into epidemics. © 2013 Sergei N Shchelkunov.

Mechanochemistry of inorganic solids is a well-established field. In the last decade mechanical treatment has become increasingly popular as a method for achieving selective and "greener" syntheses also in organic systems. New groups and researchers enter the field of mechanochemistry, often re-discovering many of the previously known facts and effects, while at the same time neglecting other important concepts. The author of this contribution has long been involved in mechanochemical research in both inorganic and organic systems. The aim of this contribution is to provide an overview of the basic concepts of mechanochemistry in relation to inorganic and organic systems. © 2013 The Royal Society of Chemistry.

This Perspective article surveys recent advances in the synthesis of mesoporous transition-metal-containing silicate materials and their use for the liquid-phase selective oxidation of organic compounds (alkanes, alkenes, aromatics, S-compounds, etc.) with environmentally friendly oxidants-molecular oxygen, hydrogen peroxide and organic hydroperoxides. A selection of the most relevant results reported thus far in the literature is provided, with particular attention paid to the issues of the nature of catalysis, catalyst stability and reusability. Approaches elaborated in recent years to create hydrothermally stable mesoporous metal silicates are considered, and the scope and limitations of such catalysts in liquid-phase oxidations are discussed. © The Royal Society of Chemistry 2014.

The term "quantum turbulence" (QT) unifies the wide class of phenomena where the chaotic set of one dimensional quantized vortex filaments (vortex tangles) appear in quantum fluids and greatly influence various physical features. Quantum turbulence displays itself differently depending on the physical situation, and ranges from quasi-classical turbulence in flowing fluids to a near equilibrium set of loops in phase transition. The statistical configurations of the vortex tangles are certainly different in, say, the cases of counterflowing helium and a rotating bulk, but in all the physical situations very similar theoretical and numerical problems arise. Furthermore, quite similar situations appear in other fields of physics, where a chaotic set of one dimensional topological defects, such as cosmic strings, or linear defects in solids, or lines of darkness in nonlinear light fields, appear in the system. There is an interpenetration of ideas and methods between these scientific topics which are far apart in other respects. The main purpose of this review is to bring together some of the most commonly discussed results on quantum turbulence, focusing on analytic and numerical studies. We set out a series of results on the general theory of quantum turbulence which aim to describe the properties of the chaotic vortex configuration, starting from vortex dynamics. In addition we insert a series of particular questions which are important both for the whole theory and for the various applications. We complete the article with a discussion of the hot topic, which is undoubtedly mainstream in this field, and which deals with the quasi-classical properties of quantum turbulence. We discuss this problem from the point of view of the theoretical results stated in the previous sections. We also included section, which is devoted to the experimental and numerical suggestions based on the discussed theoretical models. © 2012 Elsevier B.V.
