  1. Comment on "Total Negative Refraction in Real Crystals for Ballistic Electrons and Light" (Phys. Rev. Lett. 91, 157404 (2003))

    2003-01-01

    Recently, Zhang et al. (Phys. Rev. Lett. 91, 157404 (2003)) have demonstrated that an amphoteric refraction, i. e. both positive and negative refraction, may prevail at the interface of two uniaxial anisotropic crystals when their optical axes are in different directions. The authors subsequently made a correspondence between such a refraction with the negative refraction expected for Left Handed Materials (LHMs). Here we comment that the amphoteric refraction can be observed even with one un...

    The authors of the above paper call into question recent evidence on the properties of self-interstitials, I, in Ge [Cowern et al., Phys. Rev. Lett. 110, 155501 (2013)]. We show that this judgment stems from invalid model assumptions during analysis of data on B marker-layer diffusion during proton irradiation, and that a corrected analysis fully supports the reported evidence. As previously stated, I-mediated self-diffusion in Ge exhibits two distinct regimes of temperature, T: high-T, dominated by amorphous-like mono-interstitial clusters—i-morphs—with self-diffusion entropy ≈30 k, and low-T, where transport is dominated by simple self-interstitials. In a transitional range centered on 475 °C both mechanisms contribute. The experimental I migration energy of 1.84 ± 0.26 eV reported by the Münster group based on measurements of self-diffusion during irradiation at 550 °C < T < 680 °C further establishes our proposed i-morph mechanism

    The 2012 Nobel prize in physics was awarded to David Wineland, together with Serge Haroche. David Wineland received the prize for ground-breaking experimental methods that enabled the measurement and manipulation of individual quantum systems, especially systems with trapped ions. He improved a trapped ion system and opened a new quantum world leading to quantum computation. He also realized optical atomic ion clocks with unprecedented precision through his experimental research. This article briefly reviews the history of trapped ion systems, the development of trapped-ion based quantum computation, and the development of the atomic ion clock, which are closely related to Wineland's achievements.

    This article aims to provide a community-specific understanding of a subgroup of South African men who exhibit particularly high rates of hazardous alcohol consumption. Adopting a social constructionist framework, we interviewed 13 Cape Winelands men who lived on farms to explore their drinking constructions. We present three themes that shed light on problematic drinking in this group: (1) the notion of weekend binge-drinking as 'respectable' drinking, (2) drinking as shared activity that fulfils various psycho-social needs and (3) a sense of powerlessness to affect their own or their children's alcohol consumption. These findings are viewed against a specific socio-historical backdrop.

  10. Erratum: Creation of X-Ray Transparency of Matter by Stimulated Elastic Forward Scattering [Phys. Rev. Lett. 115 , 107402 (2015)

    Energy Technology Data Exchange (ETDEWEB)

    2016-01-06

    X-ray absorption by matter has long been described by the famous Beer-Lambert law. Here we show how this fundamental law needs to be modified for high-intensity coherent x-ray pulses, now available at x-ray free electron lasers, due to the onset of stimulated elastic forward scattering. We present an analytical expression for the modified polarization-dependent Beer-Lambert law for the case of resonant core-to-valence electronic transitions and incident transform limited x-ray pulses. Upon transmission through a solid, the absorption and dichroic contrasts are found to vanish with increasing x-ray intensity, with the stimulation threshold lowered by orders of magnitude through a super-radiative coherent effect. Our results have broad implications for the study of matter with x-ray lasers.

    The CLAS detector was used to obtain the first ever measurement of the electromagnetic decay of the $\\Sigma^{*+}(1385)$ from the reaction $\\gamma p \\to K^0 \\Sigma^{*+}(1385)$. A real photon beam with a maximum energy of 3.8 GeV was incident on a liquid-hydrogen target, resulting in the photoproduction of the kaon and $\\Sigma^*$ hyperon. Kinematic fitting was used to separate the reaction channel from the background processes. The fitting algorithm exploited a new method to kinematically fit neutrons in the CLAS detector, leading to the partial width measurement of $250.0\\pm56.9(stat)^{+34.3}_{-41.2}(sys)$ keV. A U-spin symmetry test using the SU(3) flavor-multiplet representation yields predictions for the $\\Sigma^{*+}(1385)\\to\\Sigma^{+}\\gamma$ and $\\Sigma^{*0}(1385)\\to\\Lambda\\gamma$ partial widths that agree with the experimental measurements.

  12. Exploring Physics with Computer Animation and PhysGL

    Science.gov (United States)

    Bensky, T. J.

    2016-10-01

    This book shows how the web-based PhysGL programming environment (http://physgl.org) can be used to teach and learn elementary mechanics (physics) using simple coding exercises. The book's theme is that the lessons encountered in such a course can be used to generate physics-based animations, providing students with compelling and self-made visuals to aid their learning. Topics presented are parallel to those found in a traditional physics text, making for straightforward integration into a typical lecture-based physics course. Users will appreciate the ease at which compelling OpenGL-based graphics and animations can be produced using PhysGL, as well as its clean, simple language constructs. The author argues that coding should be a standard part of lower-division STEM courses, and provides many anecdotal experiences and observations, that include observed benefits of the coding work.

    The present special issue contains a collection of Original Papers dedicated to Professor Johannes Heydenreich on the occasion of his 75th birthday.Johannes Heydenreich, born on 20 June 1930 in Plauen/Vogtland near Dresden, studied physics at the Pädagogische Hochschule Potsdam, where he obtained his first academic degree Dipl. Phys. in 1958. He received his doctoral degree at the Martin Luther University in Halle in 1961 and the Habilitation degree in 1969. Already during his studies in Potsdam, he showed an interest in electron microscopy due to the influence of his teacher and supervisor Prof. Picht, one of the pioneers in electron optics. His interests were strengthened when Johannes Heydenreich did the experimental work for his Diploma degree at the Institute for Experimental Physics of the University of Halle, where he met Prof. Heinz Bethge for the first time. This was the beginning of a fruitful and longstanding collaboration. In 1962 Johannes Heydenreich joined the team of the later Institute for Solid State Physics and Electron Microscopy of the Academy of Sciences of the GDR, in Halle, for which the basis was laid by Prof. Bethge in 1960.Heydenreich has been working as Assistant Director for many years and played a decisive role in introducing and organising the various techniques of electron microscopy in the institute.The research activities of Prof. Heydenreich covered a broad spectrum over the years. At the beginning of his career he made significant contributions in the field of electron mirror microscopy. After that, his main interests were focused on transmission electron microscopy, ranging from diffraction contrast analysis of crystal defects to high-resolution electron microscopy and image processing. His favourite field was studies of defect-induced phenomena in advanced materials. The so-called Bethge-Heydenreich, the book Electron Microscopy in Solid State Physics, published at first in a German edition in 1982 and later in a revised

    The nuclear receptors for heme, REV-ERBα and REV-ERBβ, play important roles in the regulation of metabolism and inflammation. Recently it was demonstrated that reduced REV-ERBα expression in hematopoetic cells in LDL receptor null mice led to increased atherosclerosis. We sought to determine if synthetic REV-ERB agonists that we have developed might have the ability to suppress atherosclerosis in this model. A previously characterized synthetic REV-ERB agonist, SR9009, was used to determine if activation of REV-ERB activity would affect atherosclerosis in LDL receptor deficient mice. Atherosclerotic plaque size was significantly reduced (p < 0.05) in mice administered SR9009 (100 mg/kg) for seven weeks compared to control mice (n = 10 per group). SR9009 treatment of bone marrow-derived mouse macrophages (BMDM) reduced the polarization of BMDMs to proinflammatory M1 macrophage while increasing the polarization of BMDMs to anti-inflammatory M2 macrophages. Our results suggest that pharmacological targeting of REV-ERBs may be a viable therapeutic option for treatment of atherosclerosis. - Highlights: • Synthetic REV-ERB agonist treatment reduced atherosclerosis in a mouse model. • Pharmacological activation of REV-ERB decreased M1 macrophage polarization. • Pharmacological activation of REV-ERB increased M2 macrophage polarization.

    Fanconi anemia (FA) is a recessive genetic disease characterized by congenital abnormalities, chromosome instability, progressive bone marrow failure (BMF), and a strong predisposition to cancer. Twenty FA genes have been identified, and the FANC proteins they encode cooperate in a common pathway that regulates DNA crosslink repair and replication fork stability. We identified a child with severe BMF who harbored biallelic inactivating mutations of the translesion DNA synthesis (TLS) gene REV7 (also known as MAD2L2), which encodes the mutant REV7 protein REV7-V85E. Patient-derived cells demonstrated an extended FA phenotype, which included increased chromosome breaks and G2/M accumulation upon exposure to DNA crosslinking agents, γH2AX and 53BP1 foci accumulation, and enhanced p53/p21 activation relative to cells derived from healthy patients. Expression of WT REV7 restored normal cellular and functional phenotypes in the patient's cells, and CRISPR/Cas9 inactivation of REV7 in a non-FA human cell line produced an FA phenotype. Finally, silencing Rev7 in primary hematopoietic cells impaired progenitor function, suggesting that the DNA repair defect underlies the development of BMF in FA. Taken together, our genetic and functional analyses identified REV7 as a previously undescribed FA gene, which we term FANCV.

  7. Analysis of translesion DNA synthesis activity of the human REV1-REV7 complex, which is a key player in radiation-induced mutagenesis

    Full text: Ionizing radiation frequently causes oxidative DNA damage in cells. It has been suggested that functions of the REV1 and REV7 genes are induction of mutations and prevention of cell death caused by ionizing radiation. With yeast Saccharomyces cerevisiae, results from a variety of investigations have demonstrated that the REV genes play a major role in induction of mutations through replication processes which directly copy the damaged DNA template during DNA replication. However, in higher eucaryotes, functions of homologues are poorly understood and appear somewhat different from the yeast case. It has been suggested that human REV1 interacts with human REV7, this being specific to higher eucaryotes. Here we show that purified human REV1 and REV7 proteins form a heterodimer in solution, which is stable through intensive purification steps. Results from biochemical analysis of the transferase reactions of the REV1-REV7 complex demonstrated, in contrast to the case of yeast Rev3 whose polymerase activity is stimulated by assembly with yeast Rev7, that human REV7 did not influence the stability, substrate specificity or kinetic parameters of the transferase reactions of REV1 protein. A possible molecular role of the REV7 subunit may be to help assembly of the REV1 protein to a large complex containing REV3 and/or other DNA polymerases in higher eucaryotes

    The human immunodeficiency virus Rev protein is a post-transcriptional activator of HIV gene expression. Rev is a nucleocytoplasmic shuttle protein that displays characteristic nuclear/nucleolar subcellular localization in various cell lines. Cytoplasmic localization of Rev occurs under various conditions disrupting Rev function. The goal of this study was to investigate the relationship between localization of Rev and its functional activity in living cells. A triple-fluorescent imaging assay, called AQ-FIND, was established for automatic quantitative evaluation of nucleocytoplasmic distribution of fluorescently tagged proteins. This assay was used to screen 500 rev genes generated by error-prone PCR for Rev mutants with different localization phenotypes. Activities of the Rev mutants were determined with a second quantitative, dual-fluorescent reporter assay. In HeLa cells, the majority of nuclear Rev mutants had activities similar to wild-type Rev. The activities of Rev mutants with abnormal cytoplasmic localization ranged from moderately impaired to nonfunctional. There was no linear correlation between subcellular distribution and levels of Rev activity. In astrocytes, nuclear Rev mutants showed similar impaired activities as the cytoplasmic wild-type Rev. Our data suggest that steady-state subcellular localization is not a primary regulator of Rev activity but may change as a secondary consequence of altered Rev function. The methodologies described here have potential for studying the significance of subcellular localization for functions of other regulatory factors

    The objective for the analysis has been to establish data for the sea at Horns Rev wind farm in the North Sea in order to assess the opportunity for using the site as test site for demonstration of wave energy devices exemplified by three different devices under development in Denmark. For comparison alternative sites like Hanstholm, Samsoe and Nissum Bredning are also assessed as well as the test centre EMEC at the Orkney Islands and the proposed test site Wave Hub at the north coast of Cornwall. The analysis shows that it is possible without major technical problems to connect 2-4 MW power generated by 3 different wave energy devices (AquaBuOY, Wave Star Energy and Wave Dragon) to the wind farm at Horns Rev (www.hornsrev.dk). The expenses for connection and regulation within the wind farm is about 200,000 DKK (30,00 EURO). On top of this comes the cost for individual sub sea cable connection to the wave devices, pull in of the sub sea cable through the existing J-tube in turbine T04 and the necessary regulation/control system in the individual wave devices to avoid damaging the power system in case of too high production. The analysis of the co-production of wind and wave power is dealt with in a separate report which shows that over a time period of half to one hour the time variation for wind generated electricity is 3 times as large as for wave energy generated power based on the actual measurement at Horns Rev. Further on the analysis shows that the wave generated power is more predictable than wind energy generated power as the power from the waves first is present about 2 hours after the wind is acting and last for 3 to 6 hours after the wind dies out; 6 to 12 hours with wind from west. The time is off course strongly depending of the direction of the wind i.e. the fetch. As this special report has a more general scope than the analysis as such it is reported in English (Annex Report II). The analysis shows that it is up to the individual device developer

    The nuclear receptor REV-ERBα is a potent, constitutive transcriptional repressor critical for the regulation of key circadian and metabolic genes. Recently, REV-ERBα's involvement in learning, neurogenesis, mood, and dopamine turnover was demonstrated suggesting a specific role in central nervous system functioning. We have previously shown that the brain expression of several core clock genes, including Rev-erbα, is modulated by sleep loss. We here test the consequences of a loss of REV-ERBα on the homeostatic regulation of sleep. EEG/EMG signals were recorded in Rev-erbα knockout (KO) mice and their wild type (WT) littermates during baseline, sleep deprivation, and recovery. Cortical gene expression measurements after sleep deprivation were contrasted to baseline. Although baseline sleep/wake duration was remarkably similar, KO mice showed an advance of the sleep/wake distribution relative to the light-dark cycle. After sleep onset in baseline and after sleep deprivation, both EEG delta power (1-4 Hz) and sleep consolidation were reduced in KO mice indicating a slower increase of homeostatic sleep need during wakefulness. This slower increase might relate to the smaller increase in theta and gamma power observed in the waking EEG prior to sleep onset under both conditions. Indeed, the increased theta activity during wakefulness predicted delta power in subsequent NREM sleep. Lack of Rev-erbα increased Bmal1, Npas2, Clock, and Fabp7 expression, confirming the direct regulation of these genes by REV-ERBα also in the brain. Our results add further proof to the notion that clock genes are involved in sleep homeostasis. Because accumulating evidence directly links REV-ERBα to dopamine signaling the altered homeostatic regulation of sleep reported here are discussed in that context. © 2016 Associated Professional Sleep Societies, LLC.

    Central to the recruitment of students into science teaching at a school like CSU, is a focus on the professional nature of teaching. The purpose of this focus is twofold: it serves to change student perceptions about teaching and it prepares students to become teachers who value continued professional development and value the science education research literature. The Noyce and PhysTEC programs at CSU place the professional nature of teaching front and center by involving students in education research projects, paid internships, attendance at conferences, and participation in a new Teacher Immersion Institute and a Science Education Journal Reading Class. This poster will focus on specific components of our teacher preparation program that were developed through these two programs. In addition we will describe how these new components provide students with diverse experiences in the teaching of science to students in the urban school district. Supported by the NSF Noyce Program (0833251) and the APS PhysTEC Program.

  13. Binding and thermodynamics of REV peptide-ctDNA interaction.

    2017-03-01

    The thermodynamics of DNA-ligand binding is important as it provides useful information to understand the details of binding processes. HIV-1 REV response element (RRE) located in the env coding region of the viral genome is reported to be well conserved across different HIV-1 isolates. In this study, the binding characteristics of Calf thymus DNA (ctDNA) and REV peptide from HIV-1 were investigated using spectroscopic (UV-visible, fluorescence, and circular dichroism (CD)) and isothermal titration calorimetric (ITC) techniques. Thermal stability and ligand binding properties of the ctDNA revealed that native ctDNA had a T m of 75.5 °C, whereas the ctDNA-REV peptide complex exhibited an incremental shift in the T m by 8 °C, indicating thermal stability of the complex. CD data indicated increased ellipticity due to large conformational changes in ctDNA molecule upon binding with REV peptide and two binding stoichiometric modes are apparent. The ctDNA experienced condensation due to large conformational changes in the presence of REV peptide and positive B→Ψ transition was observed at higher molar charge ratios. Fluorescence studies performed at several ligand concentrations revealed a gradual decrease in the fluorescence intensity of EtBr-bound ctDNA in response to increasing ligand concentrations. The fluorescence data further confirmed two stoichiometric modes of binding for ctDNA-REV peptide complex as previously observed with CD studies. The binding enthalpies were determined using ITC in the temperature range of 293 K-308 K. The ITC binding isotherm was exothermic at all temperatures examined, with low ΔH values indicating that the ctDNA-REV peptide interaction is driven largely by entropy. The heat capacity change (ΔC p ) was insignificant, an unusual finding in the area of DNA-peptide interaction studies. The variation in the values obtained for ΔH, ΔS, and ΔG with temperature further suggests that ctDNA-REV peptide interaction is entropically

    The authors have created a virtual test of vibration particle-screening using Autodesk's 3ds Max software, the MAXScript scripting language and the AGEIA PhysX physics processing unit (PPU). The affect of various parameters on screening efficiency were modeled. The parameters included vibration amplitude, frequency and direction. The length and inclination of the vibrating surface were also varied. The virtual experiment is in basic agreement with results predicted from screening theory. This shows that the virtual screener can be used for preliminary investigations and the results used to evaluate screen design. In addition it can help with theoretical research. 11 refs., 7 figs., 7 tabs.

    The HIV-1 regulatory protein Rev, which is essential for viral replication, mediates the nuclear export of unspliced viral transcripts. Rev nuclear function requires active nucleocytoplasmic shuttling, and Rev nuclear import is mediated by the recognition of its Nuclear Localisation Signal (NLS) by multiple import factors, which include transportin and importin β. However, it remains unclear which nuclear import pathway(s) predominate in vivo, and the cellular environment that modulates Rev nucleocytoplasmic shuttling remains to be characterised.

    Abstract Background The HIV-1 regulatory protein Rev, which is essential for viral replication, mediates the nuclear export of unspliced viral transcripts. Rev nuclear function requires active nucleocytoplasmic shuttling, and Rev nuclear import is mediated by the recognition of its Nuclear Localisation Signal (NLS) by multiple import factors, which include transportin and importin β. However, it remains unclear which nuclear import pathway(s) predominate in vivo, and the cellular environment that modulates Rev nucleocytoplasmic shuttling remains to be characterised. Results In our study, we have identified the cellular protein HIC (Human I-mfa domain-Containing protein) as a novel interactor of HIV-1 Rev. We demonstrate that HIC selectively interferes with Rev NLS interaction with importin β and impedes its nuclear import and function, but does not affect Rev nuclear import mediated by transportin. Hence, the molecular determinants mediating Rev-NLS recognition by importin β and transportin appear to be distinct. Furthermore, we have employed HIC and M9 M, a peptide specifically designed to inhibit the transportin-mediated nuclear import pathway, to characterise Rev nuclear import pathways within different cellular environments. Remarkably, we could show that in 293T, HeLa, COS7, Jurkat, U937, THP-1 and CEM cells, Rev nuclear import is cell type specific and alternatively mediated by transportin or importin β, in a mutually exclusive fashion. Conclusions Rev cytoplasmic sequestration by HIC may represent a novel mechanism for the control of Rev function. These studies highlight that the multivalent nature of the Rev NLS for different import receptors enables Rev to adapt its nuclear trafficking strategy.

    HIV-1 Rev escorts unspliced viral mRNAs out of the nucleus of infected cells, which allows formation of infectious HIV-1 virions. We have identified a putative DEAD box (Asp-Glu-Ala-Asp) RNA helicase, DDX1, as a cellular co-factor of Rev, through yeast and mammalian two-hybrid systems using the N-terminal motif of Rev as 'bait'. DDX1 is not a functional homolog of HIV-1 Rev, but down-regulation of DDX1 resulted in an alternative splicing pattern of Rev-responsive element (RRE)-containing mRNA, and attenuation of Gag p24 antigen production from HLfb rev(-) cells rescued by exogenous Rev. Co-transfection of a DDX1 expression vector with HIV-1 significantly increased viral production. DDX1 binding to Rev, as well as to the RRE, strongly suggest that DDX1 affects Rev function through the Rev-RRE axis. Moreover, down-regulation of DDX1 altered the steady state subcellular distribution of Rev, from nuclear/nucleolar to cytoplasmic dominance. These findings indicate that DDX1 is a critical cellular co-factor for Rev function, which maintains the proper subcellular distribution of this lentiviral regulatory protein. Therefore, alterations in DDX1-Rev interactions could induce HIV-1 persistence and targeting DDX1 may lead to rationally designed and novel anti-HIV-1 strategies and therapeutics

  5. Meteorological explanation of wake clouds at Horns Rev wind farm

    Emeis, S. [Karlsruhe Institute of Technology (Germany). Inst. for Meteorology and Climate Research

    2010-08-15

    The occurrence of wake clouds at Horns Rev wind farm is explained as mixing fog. Mixing fog forms when two nearly saturated air masses with different temperature are mixed. Due to the non-linearity of the dependence of the saturation water vapour pressure on temperature, the mixed air mass is over-saturated and condensation sets in. On the day in February 2008, when the wake clouds were observed at Horns Rev, cold and very humid air was advected from the nearby land over the warmer North Sea and led to the formation of a shallow layer with sea smoke or fog close above the sea surface. The turbines mixed a much deeper layer and thus provoked the formation of cloud trails in the wakes of the turbines. (orig.)

  6. REV-ERB and ROR: therapeutic targets for treating myopathies

    Welch, Ryan D.; Flaveny, Colin A.

    2017-08-01

    Muscle is primarily known for its mechanical roles in locomotion, maintenance of posture, and regulation of cardiac and respiratory function. There are numerous medical conditions that adversely affect muscle, myopathies that disrupt muscle development, regeneration and protein turnover to detrimental effect. Skeletal muscle is also a vital secretory organ that regulates thermogenesis, inflammatory signaling and directs context specific global metabolic changes in energy substrate preference on a daily basis. Myopathies differ in the causative factors that drive them but share common features including severe reduction in quality of life and significantly increased mortality all due irrefutably to the loss of muscle mass. Thus far clinically viable approaches for preserving muscle proteins and stimulating new muscle growth without unwanted side effects or limited efficacy has been elusive. Over the last few decades, evidence has emerged through in vitro and in vivo studies that suggest the nuclear receptors REV-ERB and ROR might modulate pathways involved in myogenesis and mitochondrial biogenesis. Hinting that REV-ERB and ROR might be targeted to treat myopathies. However there is still a need for substantial investigation into the roles of these nuclear receptors in in vivo rodent models of degenerative muscle diseases and acute injury. Although exciting, REV-ERB and ROR have somewhat confounding roles in muscle physiology and therefore more studies utilizing in vivo models of skeletal muscle myopathies are needed. In this review we highlight the molecular forces driving some of the major degenerative muscular diseases and showcase two promising molecular targets that may have the potential to treat myopathies: ROR and REV-ERB.

    HIV-1's Rev protein forms a homo-oligomeric adaptor complex linking viral RNAs to the cellular CRM1/Ran-GTP nuclear export machinery through the activity of Rev's prototypical leucine-rich nuclear export signal (NES). In this study, we used a functional fluorescently tagged Rev fusion protein as a platform to study the effects of modulating Rev NES identity, number, position, or strength on Rev subcellular trafficking, viral RNA nuclear export, and infectious virion production. We found that Rev activity was remarkably tolerant of diverse NES sequences, including supraphysiological NES (SNES) peptides that otherwise arrest CRM1 transport complexes at nuclear pores. Rev's ability to tolerate a SNES was both position and multimerization dependent, an observation consistent with a model wherein Rev self-association acts to transiently mask the NES peptide(s), thereby biasing Rev's trafficking into the nucleus. Combined imaging and functional assays also indicated that NES masking underpins Rev's well-known tendency to accumulate at the nucleolus, as well as Rev's capacity to activate optimal levels of late viral gene expression. We propose that Rev multimerization and NES masking regulates Rev's trafficking to and retention within the nucleus even prior to RNA binding. HIV-1 infects more than 34 million people worldwide causing >1 million deaths per year. Infectious virion production is activated by the essential viral Rev protein that mediates nuclear export of intron-bearing late-stage viral mRNAs. Rev's shuttling into and out of the nucleus is regulated by the antagonistic activities of both a peptide-encoded N-terminal nuclear localization signal and C-terminal nuclear export signal (NES). How Rev and related viral proteins balance strong import and export activities in order to achieve optimal levels of viral gene expression is incompletely understood. We provide evidence that multimerization provides a mechanism by which Rev transiently masks its NES peptide

  10. Mutational definition of functional domains within the Rev homolog encoded by human endogenous retrovirus K.

    Nuclear export of the incompletely spliced mRNAs encoded by several complex retroviruses, including human immunodeficiency virus type 1 (HIV-1), is dependent on a virally encoded adapter protein, termed Rev in HIV-1, that directly binds both to a cis-acting viral RNA target site and to the cellular Crm1 export factor. Human endogenous retrovirus K, a family of ancient endogenous retroviruses that is not related to the exogenous retrovirus HIV-1, was recently shown to also encode a Crm1-dependent nuclear RNA export factor, termed K-Rev. Although HIV-1 Rev and K-Rev display little sequence identity, they share the ability not only to bind to Crm1 and to RNA but also to form homomultimers and shuttle between nucleus and cytoplasm. We have used mutational analysis to identify sequences in the 105-amino-acid K-Rev protein required for each of these distinct biological activities. While mutations in K-Rev that inactivate any one of these properties also blocked K-Rev-dependent nuclear RNA export, several K-Rev mutants were comparable to wild type when assayed for any of these individual activities yet nevertheless defective for RNA export. Although several nonfunctional K-Rev mutants acted as dominant negative inhibitors of K-Rev-, but not HIV-1 Rev-, dependent RNA export, these were not defined by their inability to bind to Crm1, as is seen with HIV-1 Rev. In total, this analysis suggests a functional architecture for K-Rev that is similar to, but distinct from, that described for HIV-1 Rev and raises the possibility that viral RNA export mediated by the approximately 25 million-year-old K-Rev protein may require an additional cellular cofactor that is not required for HIV-1 Rev function.

  11. UV-induced reversion of his4 frameshift mutations in rad6, rev1, and rev3 mutants of yeast.

    Lawrence, C W; O'Brien, T; Bond, J

    1984-01-01

    The UV-induced reversion of two his4 frameshift alleles was much reduced in rad6 mutants of Saccharomyces cerevisiae, an observation that is consistent with the hypothesis that RAD6 function is required for the induction of all types of genetic alteration in misrepair mutagenesis. The reversion of these his4 alleles, together with two others of the same type, was also reduced in rev1 and rev3 mutant strains; in these, however, the extent of the reduction varied considerably with test allele used, in a manner analogous to the results in these strains for base repair substitution test alleles. The general features of UV-induced frameshift and substitution mutagenesis therefore appear quite similar, indicating that they may depend on related processes. If this conclusion is correct, greater attention must be given to integrating models which account for the production of nucleotide additions and deletions into those concerning misrepair mutagenesis.

  12. PyDecay/GraphPhys: A Unified Language and Storage System for Particle Decay Process Descriptions

    Energy Technology Data Exchange (ETDEWEB)

    Dunietz, Jesse N.; /MIT /SLAC

    2011-06-22

    To ease the tasks of Monte Carlo (MC) simulation and event reconstruction (i.e. inferring particle-decay events from experimental data) for long-term BaBar data preservation and analysis, the following software components have been designed: a language ('GraphPhys') for specifying decay processes, common to both simulation and data analysis, allowing arbitrary parameters on particles, decays, and entire processes; an automated visualization tool to show graphically what decays have been specified; and a searchable database storage mechanism for decay specifications. Unlike HepML, a proposed XML standard for HEP metadata, the specification language is designed not for data interchange between computer systems, but rather for direct manipulation by human beings as well as computers. The components are interoperable: the information parsed from files in the specification language can easily be rendered as an image by the visualization package, and conversion between decay representations was implemented. Several proof-of-concept command-line tools were built based on this framework. Applications include building easier and more efficient interfaces to existing analysis tools for current projects (e.g. BaBar/BESII), providing a framework for analyses in future experimental settings (e.g. LHC/SuperB), and outreach programs that involve giving students access to BaBar data and analysis tools to give them a hands-on feel for scientific analysis.

    Phys FilmMakers (PFM) is a new type of course in which a science expert and science communicator partner teach physics students how to make YouTube-style videos on cutting-edge scientific research within the university department. Here, we describe this new course, outline its key components and provide recommendations for others considering implementing a similar FilmMakers-style course using feedback from course tutors and students. We discuss successful and less successful teaching techniques as well as use our experience to identify areas that science students in particular often have difficulties: finding an interesting ‘hook’ for the video, imagining creative B-roll and making a succinct video by removing extraneous (though usually correct and often interesting) material. The course has two major components: workshop sessions in which students learn the key elements of film-making and independent video production where PFM students partner with senior PhD or post-doc researchers to produce a video on their research. This partnership with the department means that the videos produced serve not only as interesting ‘edutainment’ to encourage teenagers and young adults into Science, Technology, Engineering and Maths subjects, but also provide valuable outreach for the academic department.

    Human immunodeficiency virus type 1 (HIV-1) exploits multiple host factors during its replication. The REV/RRE-dependent nuclear export of unspliced/partially spliced viral transcripts needs the assistance of host proteins. Recent studies have shown that MOV10 overexpression inhibited HIV-1 replication at various steps. However, the endogenous MOV10 was required in certain step(s) of HIV-1 replication. In this report, we found that MOV10 potently enhances the nuclear export of viral mRNAs and subsequently increases the expression of Gag protein and other late products through affecting the Rev/RRE axis. The co-immunoprecipitation analysis indicated that MOV10 interacts with Rev in an RNA-independent manner. The DEAG-box of MOV10 was required for the enhancement of Rev/RRE-dependent nuclear export and the DEAG-box mutant showed a dominant-negative activity. Our data propose that HIV-1 utilizes the anti-viral factor MOV10 to function as a co-factor of Rev and demonstrate the complicated effects of MOV10 on HIV-1 life cycle. - Highlights: • MOV10 can function as a co-factor of HIV-1 Rev. • MOV10 facilitates Rev/RRE-dependent transport of viral mRNAs. • MOV10 interacts with Rev in an RNA-independent manner. • The DEAG-box of MOV10 is required for the enhancement of Rev/RRE-dependent export.

    2017-07-01

    In the past two decades, several computer software tools have been developed to investigate the motion of moving bodies in physics laboratories. In this article we report a Matlab based video tracking library, PhysTrack, primarily designed to investigate kinematics. We compare PhysTrack with other commonly available video tracking tools and outline its salient features. The general methodology of the whole video tracking process is described with a step by step explanation of several functionalities. Furthermore, results of some real physics experiments are also provided to demonstrate the working of the automated video tracking, data extraction, data analysis and presentation tools that come with this development environment. We believe that PhysTrack will be valuable for the large community of physics teachers and students already employing Matlab.

By fitting their data using the smallest wave-vector as the fitting parameter, they found this to be significantly smaller than the physical size of the graphene crystallites

    The aim of the paper is to examine the nowadays well-known wind farm wake photographs taken on 12 February 2008 at the offshore Horns Rev 1 wind farm. The meteorological conditions are described from observations from several satellite sensors quantifying clouds, surface wind vectors and sea surf...... in the wake regions with relatively high axial velocities and high turbulent kinetic energy. The wind speed is near cut-in and most turbines produce very little power. The rotational pattern of spiraling bands produces the large-scale structure of the wake fog....

  2. Mapping the binding interface between an HIV-1 inhibiting intrabody and the viral protein Rev.

    Directory of Open Access Journals (Sweden)

    Thomas Vercruysse

    Full Text Available HIV-1 Rev is the key protein in the nucleocytoplasmic export and expression of the late viral mRNAs. An important aspect for its function is its ability to multimerize on these mRNAs. We have recently identified a llama single-domain antibody (Nb190 as the first inhibitor targeting the Rev multimerization function in cells. This nanobody is a potent intracellular antibody that efficiently inhibits HIV-1 viral production. In order to gain insight into the Nb190-Rev interaction interface, we performed mutational and docking studies to map the interface between the nanobody paratope and the Rev epitope. Alanine mutants of the hyper-variable domains of Nb190 and the Rev multimerization domains were evaluated in different assays measuring Nb190-Rev interaction or viral production. Seven residues within Nb190 and five Rev residues are demonstrated to be crucial for epitope recognition. These experimental data were used to perform docking experiments and map the Nb190-Rev structural interface. This Nb190-Rev interaction model can guide further studies of the Nb190 effect on HIV-1 Rev function and could serve as starting point for the rational development of smaller entities binding to the Nb190 epitope, aimed at interfering with protein-protein interactions of the Rev N-terminal domain.

    The 12MW project with the full title '12 MW wind turbines: the scientific basis for their operation at 70 to 270 m height offshore' has the goal to experimentally investigate the wind and turbulence characteristics between 70 and 270 m above sea level and thereby establish the scientific basis relevant for the next generation of huge 12 MW wind turbines operating offshore. The report describes the experimental campaign at the Horns Rev offshore wind farm at which observations from Doppler Laser LIDAR and SODAR were collected from 3 May to 24 October 2006. The challenges for mounting and operating the instruments on the transformer platform at Horns Rev were overcome by a close collaboration between DONG energy and Risoe National Laboratory DTU. The site is presented. In particular, three tall offshore meteorological masts, up to 70 m tall, provided a useful source of meteorological data for comparison to the remotely sensed wind and turbulence observations. The comparison showed high correlation. The LIDAR and SODAR wind and turbulence observations were collected far beyond the height of the masts (up to 160 m above sea level) and the extended profiles were compared to the logarithmic wind profile. Further studies on this part of the work are on-going. Technical detail on LIDAR and SODAR are provided as well as theoretical work on turbulence and atmospheric boundary layer flow. Selected results from the experimental campaign are reported. (au)

    2017-03-01

    Full Text Available Offshore wind farm wakes were observed and photographed in foggy conditions at Horns Rev 2 on 25 January 2016 at 12:45 UTC. These new images show highly contrasting conditions regarding the wind speed, turbulence intensity, atmospheric stability, weather conditions and wind farm wake development as compared to the Horns Rev 1 photographs from 12 February 2008. The paper examines the atmospheric conditions from satellite images, radiosondes, lidar and wind turbine data and compares the observations to results from atmospheric meso-scale modelling and large eddy simulation. Key findings are that a humid and warm air mass was advected from the southwest over cold sea and the dew-point temperature was such that cold-water advection fog formed in a shallow layer. The flow was stably stratified and the freestream wind speed was 13 m/s at hub height, which means that most turbines produced at or near rated power. The wind direction was southwesterly and long, narrow wakes persisted several rotor diameters downwind of the wind turbines. Eventually mixing of warm air from aloft dispersed the fog in the far wake region of the wind farm.

    2011-01-01

    The IAEA's first effort for playing a key role in physical protection of nuclear material and facilities resulted in the publication of 'Recommendations for the physical protection of nuclear material' in 1972. These recommendations were revised by a group of experts in co-operation with the IAEA Secretariat and the revised version was published in 1975 in INFCIRC/225. The document was subsequently revised in 1977(rev.1), 1989(rev.2), in 1993(rev.3) and 1998(rev4). The Physical Protection regime in ROK has been established on the basis of INFCIRC225 rev4 since 2004 IAEA recently published The INFCIRC 225 rev5 through the 2 years expert consultations. The publication recommended 12 nuclear security fundamentals and requirements of physical protection of nuclear material and nuclear facility to the member states.

    A recently developed alternative brachytherapy seed, Cs-1 Rev2 cesium-131, has begun to be used in clinical practice. The dosimetric characteristics of this source in various media, particularly in human tissues, have not been fully evaluated. The aim of this study was to calculate the dosimetric parameters for the Cs-1 Rev2 cesium-131 seed following the recommendations of the AAPM TG-43U1 report [Rivard et al., Med. Phys. 31, 633-674 (2004)] for new sources in brachytherapy applications. Dose rate constants, radial dose functions, and anisotropy functions of the source in water, Virtual Water, and relevant human soft tissues were calculated using MCNP5 Monte Carlo simulations following the TG-43U1 formalism. The results yielded dose rate constants of 1.048, 1.024, 1.041, and 1.044 cGy h -1 U -1 in water, Virtual Water, muscle, and prostate tissue, respectively. The conversion factor for this new source between water and Virtual Water was 1.02, between muscle and water was 1.006, and between prostate and water was 1.004. The authors' calculation of anisotropy functions in a Virtual Water phantom agreed closely with Murphy's measurements [Murphy et al., Med. Phys. 31, 1529-1538 (2004)]. Our calculations of the radial dose function in water and Virtual Water have good agreement with those in previous experimental and Monte Carlo studies. The TG-43U1 parameters for clinical applications in water, muscle, and prostate tissue are presented in this work

  16. REV7, a new gene concerned with UV mutagenesis in yeast

    Three allelic mutations of a new yeast gene, which we have named REV7, have been isolated by testing 313 methyl methane sulfonate sensitive mutants for UV-induced reversion of a lys2 allele. Rev7 mutants are markedly deficient with respect to UV-induced reversion of lys2, are slightly sensitive to UV and appear to be in the RAD6 epistasis group for UV survival. Rev7-1, which is probably an amber mutation, does not appear to affect sporulation in homozygous diploids. The REV7 gene is located about 12 cM distal to HIS5 on chromosome IX. (orig.)

    In this reply, we address the main issues raised by Qian et al. regarding our recent article [J. Appl. Phys. 92, 1643 (2002)]. In particular, we reiterate the approximations used in the development of the mean-field model and demonstrate how the form used for the on-axis potential is applicable to the study of femtosecond electron packet propagation and is not in need of correction. We also repeat our assertion that the one-dimensional (1-D) fluid model developed by Qian et al. [J. Appl. Phys. 91, 462 (2002)] overestimates space-charge-induced pulse broadening and is in qualitative disagreement with femtosecond electron packet propagation dynamics. The key differences between the mean-field and 1-D fluid model are discussed and their range of applicability is clarified

    In a recent paper, Jaradat et al. [J. Math. Phys. 53, 033505 (2012)] have presented the fractional form of the electromagnetic Lagrangian density within the Riemann-Liouville fractional derivative. They claimed that the Agrawal procedure [O. P. Agrawal, J. Math. Anal. Appl. 272, 368 (2002)] is used to obtain Maxwell's equations in the fractional form, and the Hamilton's equations of motion together with the conserved quantities obtained from fractional Noether's theorem are reported. In this comment, we draw the attention that there are some serious steps of the procedure used in their work are not applicable even though their final results are correct. Their work should have been done based on a formulation as reported by Baleanu and Muslih [Phys. Scr. 72, 119 (2005)

    A. W. Love points out three alleged errors in our paper [J. Appl. Phys. 54, 3528 (1983)]. We agree that he is correct with regard to the second and third issues, but the first and perhaps most important point is correct. This regards the inequality of transmit and receive patterns of microwave antennas. The standard proof of equality of the patterns, cited by A. W. Love, is shown to be incorrect

The claim of Serov et al. of being first is refuted and many shortcomings of the hydrodynamic model for a highly quantum and degenerate graphene nanolayer are pointed out

    Mutations arising in times of cell cycle arrest may provide a selective advantage for unicellular organisms adapting to environmental changes. For multicellular organisms, however, they may pose a serious threat, in that such mutations in somatic cells contribute to carcinogenesis and ageing. The budding yeast Saccharomyces cerevisiae presents a convenient model system for studying the incidence and the mechanisms of stationary-phase mutation in a eukaryotic organism. Having studied the emergence of frameshift mutants after several days of starvation-induced cell cycle arrest, we previously reported that all (potentially error-prone) translesion synthesis (TLS) enzymes identified in S. cerevisiae did not contribute to the basal level of spontaneous stationary-phase mutations. However, we observed that an increased frequency of stationary-phase frameshift mutations, brought about by a defective nucleotide excision repair (NER) pathway or by UV irradiation, was dependent on Rev3p, the catalytic subunit of the TLS polymerase zeta (Pol {zeta}). Employing the same two conditions, we now examined the effect of deletions of the genes coding for polymerase eta (Pol {eta}) (RAD30) and Rev1p (REV1). In a NER-deficient strain background, the increased incidence of stationary-phase mutations was only moderately influenced by a lack of Pol {eta} but completely reduced to wild type level by a knockout of the REV1 gene. UV-induced stationary-phase mutations were abundant in wild type and rad30{delta} strains, but substantially reduced in a rev1{delta} as well as a rev3{delta} strain. The similarity of the rev1{delta} and the rev3{delta} phenotype and an epistatic relationship evident from experiments with a double-deficient strain suggests a participation of Rev1p and Rev3p in the same mutagenic pathway. Based on these results, we propose that the response of cell cycle-arrested cells to an excess of exo- or endogenously induced DNA damage includes a novel replication

    The Supper System Code of KAERI (SSC-K) is a best-estimate system code for analyzing a variety of off-normal or accidents in the heat transport system of a pool type LMR design. It is being developed at Korea Atomic Energy Research Institution (KAERI) on the basis of SSC-L, originally developed at BNL to analyze loop-type LMR transients. SSC-K can handle both designs of loop and pool type LMRs. SSC-K contains detailed mechanistic models of transient thermal, hydraulic, neutronic, and mechanical phenomena to describe the response of the reactor core, coolant, fuel elements, and structures to accident conditions. This report provides a revised User's Manual (rev.1) of the SSC-K computer code, focusing on phenomenological model descriptions for new thermal, hydraulic, neutronic, and mechanical modules. A comprehensive description of the models for pool-type reactor is given in Chapters 2 and 3; the steady-state plant characterization, prior to the initiation of transient is described in Chapter 2 and their transient counterparts are discussed in Chapter 3. Discussions on the intermediate heat exchanger (IHX) and the electromagnetic (EM) pump are described in Chapter 4 and 5, respectively. A model of passive safety decay heat removal system (PSDRS) is discussed in Chapter 6, and models for various reactivity feedback effects are discussed in Chapter 7. In Chapter 8, constitutive laws and correlations required to execute the SSC-K are described. New models developed for SSC-K rev.1 are two dimensional hot pool model in Chapter 9, and long term cooling model in Chapter 10. Finally, a brief description of MINET code adopted to simulate BOP is presented in Chapter 11. Based on test runs for typical LMFBR accident analyses, it was found that the present version of SSC-K would be used for the safety analysis of KALIMER. However, the further validation of SSC-K is required for real applications. It is noted that the user's manual of SSC-K will be revised later with the

  4. Molecular interaction between K-Ras and H-REV107 in the Ras signaling pathway.

    Ras proteins are small GTPases that serve as master moderators of a large number of signaling pathways involved in various cellular processes. Activating mutations in Ras are found in about one-third of cancers. H-REV107, a K-Ras binding protein, plays an important role in determining K-Ras function. H-REV107 is a member of the HREV107 family of class II tumor suppressor genes and a growth inhibitory Ras target gene that suppresses cellular growth, differentiation, and apoptosis. Expression of H-REV107 was strongly reduced in about 50% of human carcinoma cell lines. However, the specific molecular mechanism by which H-REV107 inhibits Ras is still unknown. In the present study, we suggest that H-REV107 forms a strong complex with activating oncogenic mutation Q61H K-Ras from various biochemical binding assays and modeled structures. In addition, the interaction sites between K-Ras and H-REV107 were predicted based on homology modeling. Here, we found that some structure-based mutants of the K-Ras disrupted the complex formation with H-REV107. Finally, a novel molecular mechanism describing K-Ras and H-REV107 binding is suggested and insights into new K-Ras effector target drugs are provided. Copyright © 2017 Elsevier Inc.

  5. RevManHAL: towards automatic text generation in systematic reviews.

    2017-02-09

    Systematic reviews are a key part of healthcare evaluation. They involve important painstaking but repetitive work. A major producer of systematic reviews, the Cochrane Collaboration, employs Review Manager (RevMan) programme-a software which assists reviewers and produces XML-structured files. This paper describes an add-on programme (RevManHAL) which helps auto-generate the abstract, results and discussion sections of RevMan-generated reviews in multiple languages. The paper also describes future developments for RevManHAL. RevManHAL was created in Java using NetBeans by a programmer working full time for 2 months. The resulting open-source programme uses editable phrase banks to envelop text/numbers from within the prepared RevMan file in formatted readable text of a chosen language. In this way, considerable parts of the review's 'abstract', 'results' and 'discussion' sections are created and a phrase added to 'acknowledgements'. RevManHAL's output needs to be checked by reviewers, but already, from our experience within the Cochrane Schizophrenia Group (200 maintained reviews, 900 reviewers), RevManHAL has saved much time which is better employed thinking about the meaning of the data rather than restating them. Many more functions will become possible as review writing becomes increasingly automated.

  6. Wind Farm Wake: The Horns Rev Photo Case

    2013-02-01

    Full Text Available The aim of the paper is to examine the nowadays well-known wind farm wake photographs taken on 12 February 2008 at the offshore Horns Rev 1 wind farm. The meteorological conditions are described from observations from several satellite sensors quantifying clouds, surface wind vectors and sea surface temperature as well as ground-based information at and near the wind farm, including Supervisory Control and Data Acquisition (SCADA data. The SCADA data reveal that the case of fog formation occurred 12 February 2008 on the 10:10 UTC. The fog formation is due to very special atmospheric conditions where a layer of cold humid air above a warmer sea surface re-condensates to fog in the wake of the turbines. The process is fed by warm humid air up-drafted from below in the counter-rotating swirl generated by the clock-wise rotating rotors. The condensation appears to take place primarily in the wake regions with relatively high axial velocities and high turbulent kinetic energy. The wind speed is near cut-in and most turbines produce very little power. The rotational pattern of spiraling bands produces the large-scale structure of the wake fog.

  7. HIV-1 pre-mRNA commitment to Rev mediated export through PSF and Matrin 3

    Human immunodeficiency virus gene expression and replication are regulated at several levels. Incompletely spliced viral RNAs and full-length genomic RNA contain the RRE element and are bound by the viral trans-acting protein Rev to be transported out of the nucleus. Previously we found that the nuclear matrix protein MATR3 was a cofactor of Rev-mediated RNA export. Here we show that the pleiotropic protein PSF binds viral RNA and is associated with MATR3. PSF is involved in the maintenance of a pool of RNA available for Rev activity. However, while Rev and PSF bind the viral pre-mRNA at the site of viral transcription, MATR3 interacts at a subsequent step. We propose that PSF and MATR3 define a novel pathway for RRE-containing HIV-1 RNAs that is hijacked by the viral Rev protein.

    Full Text Available When a replicative DNA polymerase stalls upon encountering a photoproduct on the template strand, it is relieved by other low-processivity polymerase(s, which insert nucleotide(s opposite the lesion. Using an alkaline sucrose density gradient sedimentation technique, we previously classified this process termed UV-induced translesion replication (UV-TLS into two types. In human cancer cells or xeroderma pigmentosum variant (XP-V cells, UV-TLS was inhibited by caffeine or proteasome inhibitors. However, in normal human cells, the process was insensitive to these reagents. Reportedly, in yeast or mammalian cells, REV3 protein (a catalytic subunit of DNA polymerase ζ is predominantly involved in the former type of TLS. Here, we studied UV-TLS in fibroblasts derived from the Rev3-knockout mouse embryo (Rev3KO-MEF. In the wild-type MEF, UV-TLS was slow (similar to that of human cancer cells or XP-V cells, and was abolished by caffeine or MG-262. In 2 cell lines of Rev3KO-MEF (Rev3−/− p53−/−, UV-TLS was not observed. In p53KO-MEF, which is a strict control for Rev3KO-MEF, the UV-TLS response was similar to that of the wild-type. Introduction of the Rev3 expression plasmid into Rev3KO-MEF restored the UV-TLS response in selected stable transformants. In some transformants, viability to UV was the same as that in the wild-type, and the death rate was increased by caffeine. Our findings indicate that REV3 is predominantly involved in UV-TLS in mouse cells, and that the REV3 translesion pathway is suppressed by caffeine or proteasome inhibitors.

    By recruiting the host protein XPO1 (CRM1), the HIV-1 Rev protein mediates the nuclear export of incompletely spliced viral transcripts. We mined data from the recently described human nuclear complexome to identify a host protein, RBM14, which associates with XPO1 and Rev and is involved in Rev function. Using a Rev-dependent p24 reporter plasmid, we found that RBM14 depletion decreased Rev activity and Rev-mediated enhancement of the cytoplasmic levels of unspliced viral transcripts. RBM14 ...

    The nuclear hormone receptor, Rev-erb beta operates as a transcriptional silencer. We previously demonstrated that exogenous expression of Rev-erb{beta}{Delta}E in skeletal muscle cells increased Srebp-1c mRNA expression. We validated these in vitro observations by injection of an expression vector driving Rev-erb{beta}{Delta}E expression into mouse tibialis muscle that resulted in increased Srebp-1c mRNA expression. Paradoxically, Rev-erb{beta} siRNA expression in skeletal muscle cells repressed Srebp-1c expression, and indicated that Rev-erb{beta} expression was necessary for Srebp-1c expression. ChIP analysis demonstrated that Rev-erb{beta} was recruited to the Srebp-1c promoter. Moreover, Rev-erb{beta} trans-activated the Srebp-1c promoter, in contrast, Rev-erb{beta} efficiently repressed the Rev-erb{alpha} promoter, a previously characterized target gene. Finally, treatment with the Rev-erb agonist (hemin) (i) increased the trans-activation of the Srebp-1c promoter by Rev-erb{beta}; and (ii) increased Rev-erb{beta} and Srebp-1c mRNA expression. These data suggest that Rev-erb{beta} has the potential to activate gene expression, and is a positive regulator of Srebp-1c, a regulator of lipogenesis.

  11. Response to 'Comment on 'Pinch current limitation effect in plasma focus'' [Appl. Phys. Lett. 94, 076101 (2009)

    International Nuclear Information System (INIS)

    Lee, S.; Saw, S. H.

    2009-01-01

    The main point of the comment [Appl. Phys. Lett. 94, 076101 (2009)] is that Eq. (2) and consequentially Eq. (3) of the commented paper [Appl. Phys. Lett. 92, 021503 (2008)] require correction. The alternative equation suggested in the comment is derived using Kirchhoff's voltage rule. The comment consider only the energy distribution in the inductive components and the resultant equation confirms a progressive lowering of the I pinch /I peak ratio as the static inductance L 0 is reduced, lowering from 0.87 to 0.31 as L 0 is reduced from 100 to 5 nH according to the revised formula corresponding to Eq. (3), compared to 0.63-0.25 according to Eq. (3). This progressive lowering of the ratio I pinch /I peak due to the inductive energy distribution is one of two factors responsible for the pinch current limitation. The other factor is the progressive reduction in the L-C interaction time compared to the current dip duration denoted by δ cap in Eq. (2). The comment does not deal with δ cap at all; hence, its conclusion based on inductive energy distribution only is not useful, since in the low L 0 region when pinch current limitation begins to manifest, δ cap becomes more and more the dominant factor. In any case, the results of the paper do not depend on Eqs. (2) and (3), which are used in the paper only for illustrative purposes

  14. Rev1, Rev3, or Rev7 siRNA Abolishes Ultraviolet Light-Induced Translesion Replication in HeLa Cells: A Comprehensive Study Using Alkaline Sucrose Density Gradient Sedimentation

    Directory of Open Access Journals (Sweden)

    Jun Takezawa

    2010-01-01

    Full Text Available When a replicative DNA polymerase stalls upon encountering a lesion on the template strand, it is relieved by other low-processivity polymerase(s, which insert nucleotide(s opposite the lesion, extend by a few nucleotides, and dissociate from the 3′-OH. The replicative polymerase then resumes DNA synthesis. This process, termed translesion replication (TLS or replicative bypass, may involve at least five different polymerases in mammals, although the participating polymerases and their roles have not been entirely characterized. Using siRNAs originally designed and an alkaline sucrose density gradient sedimentation technique, we verified the involvement of several polymerases in ultraviolet (UV light-induced TLS in HeLa cells. First, siRNAs to Rev3 or Rev7 largely abolished UV-TLS, suggesting that these 2 gene products, which comprise Polζ, play a main role in mutagenic TLS. Second, Rev1-targeted siRNA also abrogated UV-TLS, indicating that Rev1 is also indispensable to mutagenic TLS. Third, Polη-targeted siRNA also prevented TLS to a greater extent than our expectations. Forth, although siRNA to Polι had no detectable effect, that to Polκ delayed UV-TLS. To our knowledge, this is the first study reporting apparent evidence for the participation of Polκ in UV-TLS.

    Productive infection by human immunodeficiency virus type I (HIV-1) in the central nervous system (CNS) involves mainly macrophages and microglial cells. A frequency of less than 10% of human astrocytes is estimated to be infectable with HIV-1. Nonetheless, this relatively low percentage of infected astrocytes, but associated with a large total number of astrocytic cells in the CNS, makes human astrocytes a critical part in the analyses of potential HIV-1 reservoirs in vivo. Investigations in astrocytic cell lines and primary human fetal astrocytes revealed that limited HIV-1 replication in these cells resulted from low-level viral entry, transcription, viral protein processing, and virion maturation. Of note, a low ratio of unspliced versus spliced HIV-1-specific RNA was also investigated, as Rev appeared to act aberrantly in astrocytes, via loss of nuclear and/or nucleolar localization and diminished Rev-mediated function. Host cellular machinery enabling Rev function has become critical for elucidation of diminished Rev activity, especially for those factors leading to RNA metabolism. We have recently identified a DEAD-box protein, DDX1, as a Rev cellular co-factor and now have explored its potential importance in astrocytes. Cells were infected with HIV-1 pseudotyped with envelope glycoproteins of amphotropic murine leukemia viruses (MLV). Semi-quantitative reverse transcriptase-polymerase chain reactions (RT-PCR) for unspliced, singly-spliced, and multiply-spliced RNA clearly showed a lower ratio of unspliced/singly-spliced over multiply-spliced HIV-1-specific RNA in human astrocytes as compared to Rev-permissive, non-glial control cells. As well, the cellular localization of Rev in astrocytes was cytoplasmically dominant as compared to that of Rev-permissive, non-glial controls. This endogenous level of DDX1 expression in astrocytes was demonstrated directly to lead to a shift of Rev sub-cellular distribution dominance from nuclear and/or nucleolar to

    The circadian clock maintains appropriate timing for a wide range of behaviors and physiological processes. Circadian behaviors such as sleep and wakefulness are intrinsically dependent on the precise oscillation of the endogenous molecular machinery that regulates the circadian clock. The identical core clock machinery regulates myriad endocrine and metabolic functions providing a link between sleep and metabolic health. The REV-ERBs (REV-ERBα and REV-ERBβ) are nuclear receptors that are key regulators of the molecular clock and have been successfully targeted using small molecule ligands. Recent studies in mice suggest that REV-ERB-specific synthetic agonists modulate metabolic activity as well as alter sleep architecture, inducing wakefulness during the light period. Therefore, these small molecules represent unique tools to extensively study REV-ERB regulation of sleep and wakefulness. In these studies, our aim was to further investigate the therapeutic potential of targeting the REV-ERBs for regulation of sleep by characterizing efficacy, and optimal dosing time of the REV-ERB agonist SR9009 using electroencephalographic (EEG) recordings. Applying different experimental paradigms in mice, our studies establish that SR9009 does not lose efficacy when administered more than once a day, nor does tolerance develop when administered once a day over a three-day dosing regimen. Moreover, through use of a time response paradigm, we determined that although there is an optimal time for administration of SR9009 in terms of maximal efficacy, there is a 12-hour window in which SR9009 elicited a response. Our studies indicate that the REV-ERBs are potential therapeutic targets for treating sleep problems as those encountered as a consequence of shift work or jet lag. PMID:27603791

    On our previous construction [H. L. Zhen et al., Phys. Plasmas 23, 052301 (2016)] of the soliton solutions of a model describing the dynamics of the dust particles in a weakly ionized, collisional dusty plasma comprised of the negatively charged cold dust particles, hot ions, hot electrons, and stationary neutrals in the presence of an external static magnetic field, Ali et al. [Phys. Plasmas 24, 094701 (2017)] have commented that there exists a different form of Eq. (4) from that shown in Zhen et al. [Phys. Plasmas 23, 052301 (2016)] and that certain interesting phenomena with the dust neutral collision frequency ν0>0 are ignored in Zhen et al. [Phys. Plasmas 23, 052301 (2016)]. In this Reply, according to the transformation given by the Ali et al. [Phys. Plasmas 24, 094701 (2017)] comment, we present some one-, two-, and N-soliton solutions which have not been obtained in the Ali et al. [Phys. Plasmas 24, 094701 (2017)] comment. We point out that our previous solutions in Zhen et al. [Phys. Plasmas 23, 052301 (2016)] are still valid because of the similarity between the two dispersion relations of previous solutions in Zhen et al. [Phys. Plasmas 23, 052301 (2016)] and the solutions presented in this Reply. Based on our soliton solutions in this Reply, it is found that the soliton amplitude is inversely related to Zd and B0, but positively related to md and α, where α refers to the coefficient of the nonlinear term, Zd and md are the charge number and mass of a dust particle, respectively, B0 represents the strength of the external static magnetic field. We also find that the two solitons are always in parallel during the propagation.

  2. Nullbasic, a potent anti-HIV tat mutant, induces CRM1-dependent disruption of HIV rev trafficking.

    Directory of Open Access Journals (Sweden)

    Min-Hsuan Lin

    Full Text Available Nullbasic, a mutant of the HIV-1 Tat protein, has anti-HIV-1 activity through mechanisms that include inhibition of Rev function and redistribution of the HIV-1 Rev protein from the nucleolus to the nucleoplasm and cytoplasm. Here we investigate the mechanism of this effect for the first time, establishing that redistribution of Rev by Nullbasic is not due to direct interaction between the two proteins. Rather, Nullbasic affects subcellular localization of cellular proteins that regulate Rev trafficking. In particular, Nullbasic induced redistribution of exportin 1 (CRM1, nucleophosmin (B23 and nucleolin (C23 from the nucleolus to the nucleus when Rev was coexpressed, but never in its absence. Inhibition of the Rev:CRM1 interaction by leptomycin B or a non-interacting RevM10 mutant completely blocked redistribution of Rev by Nullbasic. Finally, Nullbasic did not inhibit importin β- or transportin 1-mediated nuclear import, suggesting that cytoplasmic accumulation of Rev was due to increased export by CRM1. Overall, our data support the conclusion that CRM1-dependent subcellular redistribution of Rev from the nucleolus by Nullbasic is not through general perturbation of either nuclear import or export. Rather, Nullbasic appears to interact with and disrupt specific components of a Rev trafficking complex required for its nucleocytoplasmic shuttling and, in particular, its nucleolar accumulation.

  3. Nuclear Factor 90, a cellular dsRNA binding protein inhibits the HIV Rev-export function

    Full Text Available Abstract Background The HIV Rev protein is known to facilitate export of incompletely spliced and unspliced viral transcripts to the cytoplasm, a necessary step in virus life cycle. The Rev-mediated nucleo-cytoplasmic transport of nascent viral transcripts, dependents on interaction of Rev with the RRE RNA structural element present in the target RNAs. The C-terminal variant of dsRNA-binding nuclear protein 90 (NF90ctv has been shown to markedly attenuate viral replication in stably transduced HIV-1 target cell line. Here we examined a mechanism of interference of viral life cycle involving Rev-NF90ctv interaction. Results Since Rev:RRE complex formations depend on protein:RNA and protein:protein interactions, we investigated whether the expression of NF90ctv might interfere with Rev-mediated export of RRE-containing transcripts. When HeLa cells expressed both NF90ctv and Rev protein, we observed that NF90ctv inhibited the Rev-mediated RNA transport. In particular, three regions of NF90ctv protein are involved in blocking Rev function. Moreover, interaction of NF90ctv with the RRE RNA resulted in the expression of a reporter protein coding sequences linked to the RRE structure. Moreover, Rev influenced the subcellular localization of NF90ctv, and this process is leptomycin B sensitive. Conclusion The dsRNA binding protein, NF90ctv competes with HIV Rev function at two levels, by competitive protein:protein interaction involving Rev binding to specific domains of NF90ctv, as well as by its binding to the RRE-RNA structure. Our results are consistent with a model of Rev-mediated HIV-1 RNA export that envisions Rev-multimerization, a process interrupted by NF90ctv.

  4. REV-ERBalpha participates in circadian SREBP signaling and bile acid homeostasis.

    2009-09-01

    Full Text Available In mammals, many aspects of behavior and physiology, and in particular cellular metabolism, are coordinated by the circadian timing system. Molecular clocks are thought to rely on negative feedback loops in clock gene expression that engender oscillations in the accumulation of transcriptional regulatory proteins, such as the orphan receptor REV-ERBalpha. Circadian transcription factors then drive daily rhythms in the expression of clock-controlled output genes, for example genes encoding enzymes and regulators of cellular metabolism. To gain insight into clock output functions of REV-ERBalpha, we carried out genome-wide transcriptome profiling experiments with liver RNA from wild-type mice, Rev-erbalpha knock-out mice, or REV-ERBalpha overexpressing mice. On the basis of these genetic loss- and gain-of-function experiments, we concluded that REV-ERBalpha participates in the circadian modulation of sterol regulatory element-binding protein (SREBP activity, and thereby in the daily expression of SREBP target genes involved in cholesterol and lipid metabolism. This control is exerted via the cyclic transcription of Insig2, encoding a trans-membrane protein that sequesters SREBP proteins to the endoplasmic reticulum membranes and thereby interferes with the proteolytic activation of SREBPs in Golgi membranes. REV-ERBalpha also participates in the cyclic expression of cholesterol-7alpha-hydroxylase (CYP7A1, the rate-limiting enzyme in converting cholesterol to bile acids. Our findings suggest that this control acts via the stimulation of LXR nuclear receptors by cyclically produced oxysterols. In conclusion, our study suggests that rhythmic cholesterol and bile acid metabolism is not just driven by alternating feeding-fasting cycles, but also by REV-ERBalpha, a component of the circadian clockwork circuitry.

    In Phys Plasmas 13, 073101 (2006), the drop in the space-charge-limited (SCL) current for a beam injected into a space with an open boundary is analyzed with an electromagnetic particle-in-cell code. The authors explained the power loss observed at the open boundary as the loss of electromagnetic radiation created from the deceleration of electrons in the gap, and they developed an effective voltage theory to predict the drop in the SCL current observed in the simulations. In this Comment, we show that, provided the current remains below the SCL value, the electric and magnetic fields are constant in time so that power loss from the open boundary is a dc phenomenon with no rf power leaving through the boundary. We show that the electric and magnetic fields are static in time and static fields DO NOT RADIATE. Instead, the electron beam charges the collector plate, which causes a real electrostatic electric field to develop. The electron energy loss is not due to radiation but rather to the work done by this electrostatic field on the electrons as they move across the gap. This is precisely the energy dissipated in the matched resistance across the open boundary, which is a consequence of the boundary condition. Furthermore, since a real electrostatic potential develops, the voltage drop is real and there is no need to call the voltage drop an effective voltage

    The HIV-1 Rev response element (RRE) is a 351-base element in unspliced and partially spliced viral RNA; binding of the RRE by the viral Rev protein induces nuclear export of RRE-containing RNAs, as required for virus replication. It contains one long, imperfect double helix (domain I), one branched domain (domain II) containing a high-affinity Rev-binding site, and two or three additional domains. We previously reported that the RRE assumes an "A" shape in solution and suggested that the location of the Rev binding sites in domains I and II, opposite each other on the two legs of the A, is optimal for Rev binding and explains Rev's specificity for RRE-containing RNAs. Using SAXS and a quantitative functional assay, we have now analyzed a panel of RRE mutants. All the results support the essential role of the A shape for RRE function. Moreover, they suggest that the distal portion of domain I and the three crowning domains all contribute to the maintenance of the A shape. Domains I and II are necessary and sufficient for substantial RRE function, provided they are joined by a flexible linker that allows the two domains to face each other. IMPORTANCE Retroviral replication requires that some of the viral RNAs transcribed in the cell nucleus be exported to the cytoplasm without being spliced. To achieve this, HIV-1 encodes a protein, Rev, which binds to a complex, highly structured element within viral RNA, the Rev Response Element (RRE), and escorts RRE-containing RNAs from the nucleus. We previously reported that the RRE is "A"-shaped and suggested that this architecture, with the 2 legs opposite one another, can explain the specificity of Rev for the RRE. We have analyzed the functional contributions of individual RRE domains, and now report that several domains contribute, with some redundancy, to maintenance of the overall RRE shape. The data strongly support the hypothesis that the opposed placement of the 2 legs is essential for RRE function. Copyright © 2017

    The bovine immunodeficiency virus (BIV) Rev shuttling protein contains nuclear/nucleolar localization signals and nuclear import/export mechanisms that are novel among lentivirus Rev proteins. Several viral proteins localize to the nucleolus, which may play a role in processes that are essential to the outcome of viral replication. Although BIV Rev localizes to the nucleoli of transfected/infected cells and colocalizes with one of its major proteins, nucleophosmin (NPM1, also known as B23), the role of the nucleolus and B23 in BIV replication remains to be determined. Here, we demonstrate for the first time that BIV Rev interacts with nucleolar phosphoprotein B23 in cells. Using small interfering RNA (siRNA) technology, we show that depletion of B23 expression inhibits virus production by BIV-infected cells, indicating that B23 plays an important role in BIV replication. The interaction between Rev and B23 may represent a potential new target for the development of antiviral drugs against lentiviruses. Copyright © 2017 Elsevier Inc. All rights reserved.

    Thanks to a main funding of Region des Pays de la Loire, the sea test site SEM-REV has been developed by Ecole Centrale de Nantes since 2007 to test both Wave Energy Converters and Floating Wind Turbine in real sea conditions. The sea test site is equipped with a set of oceanographic sensors and with an electric cable of 8 MW, connected to the French grid. The project is located close to Le Croisic, Western coast of France. SEM-REV is one of the main test facilities operated by Ecole Centrale de Nantes to support MRE technologies development. After presenting the initial motivations of the SEM-REV development, the paper describes, in parts 1 and 2, the complete administrative and technical processes that were followed to reach SEM-REV commissioning in 2014. The third part is focused on the exploitation process, including technical and contractual specifications imposed to the MRE developers for installation, tests and decommissioning phases. Some words are given also on the R and D projects using the SEM-REV in-situ monitoring system: prediction of environmental conditions, bio-fooling, acoustic impact. Even if operational phase is not started, expected extensions of the tests site are listed. (authors)

    2009-01-01

    A recent publication [F. I. Parra and P. J. Catto, Plasma Phys. Controlled Fusion 50, 065014 (2008)] warned against the use of the lower order gyrokinetic Poisson equation at long wavelengths because the long wavelength, radial electric field must remain undetermined to the order the equation is obtained. Another reference [W. W. Lee and R. A. Kolesnikov, Phys. Plasmas 16, 044506 (2009)] criticizes these results by arguing that the higher order terms neglected in the most common gyrokinetic Poisson equation are formally smaller than the terms that are retained. This argument is flawed and ignores that the lower order terms, although formally larger, must cancel without determining the long wavelength, radial electric field. The reason for this cancellation is discussed. In addition, the origin of a nonlinear term present in the gyrokinetic Poisson equation [F. I. Parra and P. J. Catto, Plasma Phys. Controlled Fusion 50, 065014 (2008)] is explained.

    The role of rev3 gene function in uv-induced mutagenesis in the yeast Saccharomyces cerevisiae has been examined by determining the reversion of 12 well-defined cyc1 mutations in diploid strains homozygous for the rev3-1 or rev3-3 allale. The 12 cyc1 alleles include one ochre, one amber, four initiation, two proline missense, and four frameshift mutations. We find that the rev3 mutations reduce the frequency of UV-induced reversion of all of the cyc1 alleles, though different classes of alleles respond to a different extent. These results imply that the rev3 gene function is required for the production of a wide variety of mutational events, though probably not all, and show that each of the three rev loci have different mutational phenotypes. Such diverse phenotypes are not predicted by the unitary model for bacterial mutagenes, suggesting that this is at best an incomplete description of eukaryotic mutagenesis

    Full Text Available A field trial was conducted in a camel brucellosis-free herd to evaluate antibody response to the Brucella melitensis Rev.1 vaccine in camels and assess shedding of the vaccine strain in milk. Twenty eight camels were divided into four groups according to their age and vaccination route. Groups A (n=3 and B (n=3 consisted of non-pregnant lactating female camels, vaccinated through subcutaneous and conjunctival routes, respectively. Groups C (n=10 consisted of 8-11 months old calves vaccinated through conjunctival route. The rest of the herd (n=12 composed of female and young camels were not vaccinated and were considered as the control group. Each animal from groups A, B and C was given the recommended dose of 2 x 109 colony forming units of Rev.1 vaccine irrespective of age or route of vaccination. Blood samples were collected from all the animals at the time of vaccination and at weekly, bi-weekly and monthly interval until 32 weeks post vaccination and from controls at weeks 8 and 24. The serological tests used were modified Rose Bengal Test, sero-agglutination test, and an indirect Enzyme Linked Immunosorbent Assay. Milk samples were collected from all vaccinated female camels and tested for the presence of Rev.1 vaccine strain. Most vaccinated animals started to show an antibody response at week 2 and remained positive until week 16. By week 20 post-vaccination all animals in the three groups were tested negative for Brucella antibodies. Bacteriological analysis of milk samples did not allow any isolation of Brucella melitensis. All samples were found Brucella negative in PCR analysis. The results of this study indicate that the Rev.1 vaccine induces seroconversion in camels. Rev.1 vaccine strain is not excreted in the milk of camels. These findings are promising as to the safe use of the Rev.1 vaccine in camels.

    The simple fact that proteins are built from 20 amino acids while DNA only contains four different bases, means that the 'signal-to-noise ratio' in protein sequence alignments is much better than in alignments of DNA. Besides this information-theoretical advantage, protein alignments also benefit...... proteins. It is therefore preferable to align coding DNA at the amino acid level and it is for this purpose we have constructed the program RevTrans.

    2012-11-01

    Full Text Available By diversifying the biological effector functions of antibodies, class switch DNA recombination (CSR plays a critical role in the maturation of the immune response. It is initiated by activation-induced cytidine deaminase (AID-mediated deoxycytosine deamination, yielding deoxyuridine (dU, and dU glycosylation by uracil DNA glycosylase (Ung in antibody switch (S region DNA. Here we showed that the translesion DNA synthesis polymerase Rev1 directly interacted with Ung and targeted in an AID-dependent and Ung-independent fashion the S regions undergoing CSR. Rev1−/− Ung+/+ B cells reduced Ung recruitment to S regions, DNA-dU glycosylation, and CSR. Together with an S region spectrum of mutations similar to that of Rev1+/+ Ung−/− B cells, this suggests that Rev1 operates in the same pathway as Ung, as emphasized by further decreased CSR in Rev1−/− Msh2−/− B cells. Rescue of CSR in Rev1−/− B cells by a catalytically inactive Rev1 mutant shows that the important role of Rev1 in CSR is mediated by Rev1’s scaffolding function, not its enzymatic function.

  3. Determining the REV for Fracture Rock Mass Based on Seepage Theory

    2017-01-01

    Full Text Available Seepage problems of the fractured rock mass have always been a heated topic within hydrogeology and engineering geology. The equivalent porous medium model method is the main method in the study of the seepage of the fractured rock mass and its engineering application. The key to the method is to determine a representative elementary volume (REV. The FractureToKarst software, that is, discrete element software, is a main analysis tool in this paper and developed by a number of authors. According to the standard of rock classification established by ISRM, this paper aims to discuss the existence and the size of REV of fractured rock masses with medium tractility and provide a general method to determine the existence of REV. It can be gleaned from the study that the existence condition of fractured rock mass with medium tractility features average fracture spacing smaller than 0.6 m. If average fracture spacing is larger than 0.6 m, there is no existence of REV. The rationality of the model is verified by a case study. The present research provides a method for the simulation of seepage field in fissured rocks.

    Translesion synthesis (TLS) is an important mechanism through which proliferating cells tolerate DNA damage during replication. The mutagenic Rev1/Polζ-dependent branch of TLS helps cancer cells survive first-line genotoxic chemotherapy and introduces mutations that can contribute to the acquired resistance so often observed with standard anticancer regimens. As such, inhibition of Rev1/Polζ-dependent TLS has recently emerged as a strategy to enhance the efficacy of first-line chemotherapy and reduce the acquisition of chemoresistance by decreasing tumor mutation rate. The TLS DNA polymerase Rev1 serves as an integral scaffolding protein that mediates the assembly of the active multiprotein TLS complexes. Protein-protein interactions (PPIs) between the C-terminal domain of Rev1 (Rev1-CT) and the Rev1-interacting region (RIR) of other TLS DNA polymerases play an essential role in regulating TLS activity. To probe whether disrupting the Rev1-CT/RIR PPI is a valid approach for developing a new class of targeted anticancer agents, we designed a fluorescence polarization-based assay that was utilized in a pilot screen for small molecule inhibitors of this PPI. Two small molecule scaffolds that disrupt this interaction were identified, and secondary validation assays confirmed that compound 5 binds to Rev1-CT at the RIR interface. Finally, survival and mutagenesis assays in mouse embryonic fibroblasts and human fibrosarcoma HT1080 cells treated with cisplatin and ultraviolet light indicate that these compounds inhibit mutagenic Rev1/Polζ-dependent TLS in cells, validating the Rev1-CT/RIR PPI for future anticancer drug discovery and identifying the first small molecule inhibitors of TLS that target Rev1-CT.

    In the present study forty-four Greek endemic strains of Br. melitensis and three reference strains were genotyped by Multi locus Variable Number Tandem Repeat (ML-VNTR) analysis based on an eight-base pair tandem repeat sequence that was revealed in eight loci of Br. melitensis genome. The forty-four strains were discriminated from the vaccine strain Rev-1 by Restriction Fragment Length Polymorphism (RFLP) and Denaturant Gradient Gel Electrophoresis (DGGE). The ML-VNTR analysis revealed that endemic, reference and vaccine strains are genetically closely related, while most of the loci tested (1, 2, 4, 5 and 7) are highly polymorphic with Hunter-Gaston Genetic Diversity Index (HGDI) values in the range of 0.939 to 0.775. Analysis of ML-VNTRs loci stability through in vitro passages proved that loci 1 and 5 are non stable. Therefore, vaccine strain can be discriminated from endemic strains by allele's clusters of loci 2, 4, 6 and 7. RFLP and DGGE were also employed to analyse omp2 gene and reveled different patterns among Rev-1 and endemic strains. In RFLP, Rev-1 revealed three fragments (282, 238 and 44 bp), while endemic strains two fragments (238 and 44 bp). As for DGGE, the electrophoretic mobility of Rev-1 is different from the endemic strains due to heterologous binding of DNA chains of omp2a and omp2b gene. Overall, our data show clearly that it is feasible to genotype endemic strains of Br. melitensis and differentiate them from vaccine strain Rev-1 with ML-VNTR, RFLP and DGGE techniques. These tools can be used for conventional investigations in brucellosis outbreaks.

    Elsam and Eltra built the offshore demonstration wind farm at Horns Rev in the North Sea. Elsam is the owner and is responsible for the operation of the wind farm. Eltra is responsible for the connection of the wind farm to the national onshore grid. In the summer months of 2002, Elsam constructed the world's largest offshore wind farm off the Danish west coast. The wind farm is sited 14-20 km into the North Sea, west of Blaevands Huk. The first wind turbine was erected in May 2002 and the last wind turbine tower of a total of 80 was in place by August 2002. The construction work was completed with the last connecting cables sluiced down in September 2002. All the wind turbines were in production by December 2002. The expected impact of the wind farm will primarily be an alternation of habitats due to the introduction of hard bottom substrates as wind turbine towers and scour protections. A continuous development in the epifouling communities will be expected together with an introduction of new or alien species in the area. The indigenous benthic community in the area of Horns Rev can be characterised by infauna species belonging to the Goniadella-Spisula community. This community is typical of sandbanks in the North Sea area, although communities in such areas are very variable and site-specific. Character species used as indicators for environmental changes in the Horns Rev area are the bristle worms Goniadella bobretzkii, Ophelia borealis, Psione remota and Orbinia sertulata and the mussels Goodallia triangularis and Spisula solida. In connection with the implementation of the monitoring programme concerning the ecological impact of the introduction of hard substrate related to the Horns Rev Wind Farm, surveys on hard bottom substrate was conducted in March 2003 and in September 2003. This report describes the first year results of surveys on hard substrate after the completion of the offshore wind farm at Horns Rev. (au)

    DNA Directed Polymerase Zeta Catalytic Subunit (REV3L) has recently emerged as an important oncogene. Although the expressions of REV3L are similar in normal and cancer cells, several mutations in REV3L have been shown to play important roles in cancer. These mutations cause proteins misfolding and mislocalization, which in turn alters their interactions and biological functions. miRNAs play important regulatory roles during the progression and metastasis of several human cancers. This study was undertaken to determine how changes in the location and interactions of REV3L regulate colon cancer progression. REV3L protein mislocalization confirmed from the immunostaining results and the known interactions of REV3L was found to be broken as seen from the PLA assay results. The mislocalized REV3L might interact with new proteins partners in the cytoplasm which in turn may play role in regulating colon cancer progression. hsa-miR-340 (miR-340), a microRNA down-regulated in colon cancer, was used to bind to and downregulate REV3L, and found to control the proliferation and induce the apoptosis of colon cancer cells (HCT-116 and DLD-1) via the MAPK pathway. Furthermore, this down-regulation of REV3L also diminished colon cancer cell migration, and down-regulated MMP-2 and MMP-9. Combined treatment of colon cancer cells with miR-340 and 5-FU enhanced the inhibitory effects of 5-FU. In addition, in vivo experiments conducted on nude mice revealed tumor sizes were smaller in a HCT-116-miR-340 injected group than in a HCT-116-pCMV injected group. Our findings suggest mutations in REV3L causes protein mislocalization to the cytoplasm, breaking its interaction and is believed to form new protein interactions in cytoplasm contributing to colon cancer progression. Accordingly, microRNA-340 appears to be a good candidate for colon cancer therapy. PMID:29435169

    Brucella melitensis Rev.1 is an avirulent strain that is widely used as a live vaccine to control brucellosis in small ruminants. Although an assembled draft version of Rev.1 genome has been available since 2009, this genome has not been investigated to characterize this important vaccine. In the present work, we used the draft genome of Rev.1 to perform a thorough genomic comparison and sequence analysis to identify and characterize the panel of its unique genetic markers. The draft genome of Rev.1 was compared with genome sequences of 36 different Brucella melitensis strains from the Brucella project of the Broad Institute of MIT and Harvard. The comparative analyses revealed 32 genetic alterations (30 SNPs, 1 single-bp insertion and 1 single-bp deletion) that are exclusively present in the Rev.1 genome. In silico analyses showed that 9 out of the 17 non-synonymous mutations are deleterious. Three ABC transporters are among the disrupted genes that can be linked to virulence attenuation. Out of the 32 mutations, 11 Rev.1 specific markers were selected to test their potential to discriminate Rev.1 using a bi-directional allele-specific PCR assay. Six markers were able to distinguish between Rev.1 and a set of control strains. We succeeded in identifying a panel of 32 genome-specific markers of the B. melitensis Rev.1 vaccine strain. Extensive in silico analysis showed that a considerable number of these mutations could severely affect the function of the associated genes. In addition, some of the discovered markers were able to discriminate Rev.1 strain from a group of control strains using practical PCR tests that can be applied in resource-limited settings.

  16. iNR-PhysChem: a sequence-based predictor for identifying nuclear receptors and their subfamilies via physical-chemical property matrix.

    Directory of Open Access Journals (Sweden)

    Full Text Available Nuclear receptors (NRs form a family of ligand-activated transcription factors that regulate a wide variety of biological processes, such as homeostasis, reproduction, development, and metabolism. Human genome contains 48 genes encoding NRs. These receptors have become one of the most important targets for therapeutic drug development. According to their different action mechanisms or functions, NRs have been classified into seven subfamilies. With the avalanche of protein sequences generated in the postgenomic age, we are facing the following challenging problems. Given an uncharacterized protein sequence, how can we identify whether it is a nuclear receptor? If it is, what subfamily it belongs to? To address these problems, we developed a predictor called iNR-PhysChem in which the protein samples were expressed by a novel mode of pseudo amino acid composition (PseAAC whose components were derived from a physical-chemical matrix via a series of auto-covariance and cross-covariance transformations. It was observed that the overall success rate achieved by iNR-PhysChem was over 98% in identifying NRs or non-NRs, and over 92% in identifying NRs among the following seven subfamilies: NR1--thyroid hormone like, NR2--HNF4-like, NR3--estrogen like, NR4--nerve growth factor IB-like, NR5--fushi tarazu-F1 like, NR6--germ cell nuclear factor like, and NR0--knirps like. These rates were derived by the jackknife tests on a stringent benchmark dataset in which none of protein sequences included has ≥60% pairwise sequence identity to any other in a same subset. As a user-friendly web-server, iNR-PhysChem is freely accessible to the public at either http://www.jci-bioinfo.cn/iNR-PhysChem or http://icpr.jci.edu.cn/bioinfo/iNR-PhysChem. Also a step-by-step guide is provided on how to use the web-server to get the desired results without the need to follow the complicated mathematics involved in developing the predictor. It is anticipated that iNR-PhysChem may

    We show in this Response that the nonlinear Poisson's equation in our original paper derived from the drift kinetic approach can be verified by using the nonlinear gyrokinetic Poisson's equation of Dubin et al. (Phys. Fluids 26, 3524 (1983)). This nonlinear contribution in φ 2 is indeed of the order of k # perpendicular# 4 in the long wavelength limit and remains finite for zero ion temperature, in contrast to the nonlinear term by Parra and Catto (Plasma Phys. Control. Fusion 50, 065014 (2008)), which is of the order of k # perpendicular# 2 and diverges for T i → 0. For comparison, the leading term for the gyrokinetic Poisson's equation in this limit is of the order of k # perpendicular# 2 φ.

  5. Rev and Rex proteins of human complex retroviruses function with the MMTV Rem-responsive element

    Directory of Open Access Journals (Sweden)

    Dudley Jaquelin P

    2009-02-01

    Full Text Available Abstract Background Mouse mammary tumor virus (MMTV encodes the Rem protein, an HIV Rev-like protein that enhances nuclear export of unspliced viral RNA in rodent cells. We have shown that Rem is expressed from a doubly spliced RNA, typical of complex retroviruses. Several recent reports indicate that MMTV can infect human cells, suggesting that MMTV might interact with human retroviruses, such as human immunodeficiency virus (HIV, human T-cell leukemia virus (HTLV, and human endogenous retrovirus type K (HERV-K. In this report, we test whether the export/regulatory proteins of human complex retroviruses will increase expression from vectors containing the Rem-responsive element (RmRE. Results MMTV Rem, HIV Rev, and HTLV Rex proteins, but not HERV-K Rec, enhanced expression from an MMTV-based reporter plasmid in human T cells, and this activity was dependent on the RmRE. No RmRE-dependent reporter gene expression was detectable using Rev, Rex, or Rec in HC11 mouse mammary cells. Cell fractionation and RNA quantitation experiments suggested that the regulatory proteins did not affect RNA stability or nuclear export in the MMTV reporter system. Rem had no demonstrable activity on export elements from HIV, HTLV, or HERV-K. Similar to the Rem-specific activity in rodent cells, the RmRE-dependent functions of Rem, Rev, or Rex in human cells were inhibited by a dominant-negative truncated nucleoporin that acts in the Crm1 pathway of RNA and protein export. Conclusion These data argue that many retroviral regulatory proteins recognize similar complex RNA structures, which may depend on the presence of cell-type specific proteins. Retroviral protein activity on the RmRE appears to affect a post-export function of the reporter RNA. Our results provide additional evidence that MMTV is a complex retrovirus with the potential for viral interactions in human cells.

  7. Determination of Geometrical REVs Based on Volumetric Fracture Intensity and Statistical Tests

    2018-05-01

    Full Text Available This paper presents a method to estimate a representative element volume (REV of a fractured rock mass based on the volumetric fracture intensity P32 and statistical tests. A 150 m × 80 m × 50 m 3D fracture network model was generated based on field data collected at the Maji dam site by using the rectangular window sampling method. The volumetric fracture intensity P32 of each cube was calculated by varying the cube location in the generated 3D fracture network model and varying the cube side length from 1 to 20 m, and the distribution of the P32 values was described. The size effect and spatial effect of the fractured rock mass were studied; the P32 values from the same cube sizes and different locations were significantly different, and the fluctuation in P32 values clearly decreases as the cube side length increases. In this paper, a new method that comprehensively considers the anisotropy of rock masses, simplicity of calculation and differences between different methods was proposed to estimate the geometrical REV size. The geometrical REV size of the fractured rock mass was determined based on the volumetric fracture intensity P32 and two statistical test methods, namely, the likelihood ratio test and the Wald–Wolfowitz runs test. The results of the two statistical tests were substantially different; critical cube sizes of 13 m and 12 m were estimated by the Wald–Wolfowitz runs test and the likelihood ratio test, respectively. Because the different test methods emphasize different considerations and impact factors, considering a result that these two tests accept, the larger cube size, 13 m, was selected as the geometrical REV size of the fractured rock mass at the Maji dam site in China.

    Elsam and Eltra have built the offshore demonstration wind farm at Horns Rev in the North Sea. Elsam is the owner and is responsible for the operation of the wind farm. Eltra is responsible for the connection of the wind farm to the national onshore grid. In the summer months of 2002, Elsam constructed the world's largest offshore wind farm at the Danish west coast. The wind farm is located 14-20 km into the North Sea, west of Blaevands Huk. The first wind turbine foundation was in place in March 2002 and the last mono-pile was in place in August 2002 for a total of 80. The construction work was completed with the last connecting cables sluiced down in September 2002. All the wind turbines were in production in December 2002. The expected impact from the wind farm will primarily be an alternation of habitats due to the introduction of hard bottom substrates as wind mono-piles and scour protections. A continuous development in the epifouling communities will be expected together with an introduction of new or alien species in the area. The indigenous benthic community in the area of Horn Rev can be characterised by infauna species belonging to the Goniadella-Spisula community. This community is typical of sandbanks in the North Sea area, although communities in such areas are very variable and site specific. Character species used as indicators for environmental changes in the Horns Rev area are the bristle worms Goniadella bobretzkii, Ophelia borealis, Psione remota and Orbinia sertulata and the mussels Goodallia triangularis and Spisula solida. In connection with the implementation of the monitoring programme concerning the ecological impact of the introduction of hard substrate related to the Horns Rev Wind Farm, surveys on hard bottom substrates were initialised in March 2003 with monitoring conducted in September 2003 and March and September 2004. This report describes the results from surveys on hard substrates in 2004. (au)

    Full Text Available Many of the known risk factors associated with low birth weight (LB W infants, such as socio-economic status, ethnicity, genetic makeup, and obstetric history, are not within a woman’s immediate control. However, there are many things that a woman can do to improve her chances of having a normal healthy child. Lifestyle behaviours, such as cigarette smoking, nutrition and the use of alcohol, play an important role in determining the growth of the foetus. There is a high rate of low birth weight infants bom to women living and working on the farms in the Western Cape. Very little is known about the knowledge, attitudes and practices of the women living and working on the farms that may be influencing their pregnancy outcomes. The aim of this qualitative exploratory study was to establish the knowledge, attitudes and practices of reproductive age women related to lifestyle factors such as alcohol use, smoking and nutrition, and the perceptions of these factors by health care workers, in Stellenbosch and Vredendal areas (small towns in the Western Cape.

    Full Text Available Clerical masculinities, much like their lay/secular counterparts, often appear unchang¬ing because they are the products of naturalization processes. Clerical masculinities, however, are far from stable, for they live and breathe the dynamics of both their socio-religious context and their secular “others”. The BBC sitcom Rev. (BBC2, UK 2010–2014 is a refreshing take on the everyday life and problems of a vicar in the Church of England trying to avoid stereotypes that often come with clerical roles. Rev. (2010–2014 can be interpreted as an attempt to explore the negotiation processes of masculinity within an institution that is involved in the “production” of religion and gender roles. It shows that being a man in an institutional setting is as much a perfor¬mance as it is a more or less successful negotiation of other people’s expectations and one’s own worldview. In particular, the main male clerical characters in Rev. (2010– 2014 inhabit a position of power but all have their flaws. They can best be understood as losers whose clash with masculine systems renders them more human.

  12. Guidance and considerations for implementation of INFCIRC/225/Rev.3, the physical protection of nuclear material

    International Nuclear Information System (INIS)

    1997-09-01

    The Physical Protection of Nuclear Material, INFCIRC/225/Rev.3, provides recommendations for the physical protection of nuclear material against theft in use, storage and transport, whether national or international and whether peaceful or military, and contains provisions relating to the sabotage of nuclear material or facilities. The recommendations contained in INFCIRC/225/Rev.3 detail the elements that should be included in a State's system of physical protection. It also recognizes the adverse health and safety consequences arising from the theft of nuclear material and the sabotage of nuclear material or facilities. Most industrial and developing countries use these recommendations to some extent in the establishment and operation of their physical protection systems. Although INFCIRC/225/Rev.3 provides recommendations for protecting materials and facilities from theft or sabotage, it does not provide in-depth details for these recommendations. In June 1996, the IAEA convened a consultants meeting to consider this matter. This report is the result of continuing discussions and drafts over a period of nine months. The intent of this guidance is to provide a broader basis for relevant State organizations to prescribe appropriate requirements for the use of nuclear materials which are compatible with accepted international practice

    It is shown that the oscillation named by Shukla as the 'Shukla mode' is well known in the plasma physics literature as the magnetic drift wave. In addition, the instability of these modes in a cold plasma as claimed by Shukla et al. [Phys. Plasmas 11, 1732 (2004)] does not exist and is due to a mathematical error in their analysis. Also the 'new' resonance and new cutoff frequencies claimed by Shukla et al. and Mamum et al. [Phys Plasmas 11, 2307 (2004)] have been known in the published literature for decades

    The present report presents the results of three bird surveys conducted in the Horns Rev area during the second half of 2001. Due to poor weather conditions in December 2001, the last survey was, however, performed on 7 January 2002. The surveys are part of the base-line investigations of birds performed in relation to the proposed construction of an offshore wind farm at Horns Rev in the Danish part of the North Sea ca 14 km southwest of Blaevandshuk. The results of the surveys during August 2001 - January 2002 are presented together with the results obtained during the period August 2000 - April 2001, and are also compared to results obtained during the period August 1999 - April 2000. Based on the distribution of the most abundant bird species recorded during 16 aerial surveys performed during August 1999 - January 2002, there were no indications that the wind farm area was of any particular importance to the birds' exploitation of the Horns Rev area. Fish-eating species like divers, gannet, terns, auks and gulls generally showed scattered and variable distributions, mainly occurring in the areas north and south of Horns Rev, and with low numbers on the reef proper and within the planned wind farm area. The distribution of benthic foraging species, eider and common Scoter, showed that they mainly exploited the coastal parts of the area off Blaevandshuk and Skallingen, although common scoter was found in relatively high numbers on the southeast slopes of the Horns Rev and within the wind farm area in the April 2001 survey. Common scoters occurred in very high numbers in January 2002. This was probably related to increased immigration of birds from the inner Danish waters during a cold period in late December 2001. Preference analyses of bird exploitation of the Horns Rev area showed that if the birds completely avoid the wind farm area after erection of the wind turbines, this will affect less than 1% of the various species, except divers where 1.58% will be

    Recently, Mu et al. [J. Appl. Phys. 115, 044512 (2014)] have developed an analytic approach to describe some special shapes of a single-wall carbon nanotube (SWCNT) under hydrostatic pressure. These authors have found approximate analytic expressions for the parametric equations of the tube cross section profile and its curvature at the convex-to-concave transition pressure using a shell-like 2D continuum model describing the shapes of such nanotubes. In this comment, we provide additional insight into this problem taking into account the exact analytic representation of the shapes that a SWCNT attains when subjected to hydrostatic pressure according to the very same continuum model.

In the comment it is pointed out that for untrapped electrons a full kinetic equation, which includes dependences on spatial coordinates and energies, has to be used for the electron velocity distribution function determination. It is also unclear what probe theories Zobnin et al. have used in their paper for the calculation of electron current to the discharge tube wall.

    An Environmental Impact Assessment (EIA) of a planned 150 MW offshore wind farm at Horns Rev has been carried out for the marine biology and sea bottom in the area, and includes vegetation and benthic fauna. The study forms part of a total EIA of the planned offshore wind farm. This EIA study has been drawn up in accordance with the guidelines laid down by the Ministry of Environment and Energy in the publication, 'Guidelines for preparation of EIAstudies for offshore wind farms. Horns Rev is situated off Blaevands Huk, which is Denmark's most westerly point. It is a shallow reef with water depths between 2 and 9 metres and is primarily composed of sand, gravel and pebbles. The area designated for the wind farm lies directly south of Horns Rev and is dominated by sand with a median particle size of 0.3 mm. Along the edges, towards areas of greater depth, the particle size increases. There are areas of fine sand in the deepest area, and in isolated pockets within the proposed wind farm site. The sediment is characterised by a very low (<1%) organic matter content. On the basis of the expected impact from the establishment of the wind farm, it is not deemed necessary to carry out special programmes during the construction phase for monitoring of the environmental-biological conditions. A monitoring and control programme is recommended during the production phase in order to follow the copper concentration in bivalves, or alternatively to initiate recovery or elimination of the copper-laden waste. A control programme is recommended during the production phase in order to follow the establishment and succession of the fouling community on the wind turbine foundations and scour-protecting revetments.

    This article proposes a new algorithm to improvethe rate control efficiency of enhanced reverse link mediumaccess control (RLMAC) in the code division multiple access(CDMA) lx EV-DO release A(Rev. A) system. The newalgorithm brings reverse access terminal (AT) pilot power tothe RLMAC rate control procedure and makes it easier for alow pilot power user to increase its data rate when the systemis slightly loaded and harder to decrease its date rate when thesystem is heavily loaded. Numerical results of system levelsimulations show that the new algorithm can bring highersystem throughput, lower AT transmission power, and lowersystem load.

    We have identified a novel, multiple spliced, subgenomic mRNA species in MMTV producing cells of different origin containing an open reading frame encoding a 39-kDa Rev-like protein, Rem (regulator of expression of MMTV). An EGFP-Rem fusion protein is shown to be predominantly in the nucleolus. Further leptomycin B inhibits the nuclear export of nonspliced MMTV transcripts, implicating Rem in nuclear export by the Crm1 pathway in MMTV. Rem is thus reminiscent of the Rec protein from the related endogenous human retrovirus, HERV-K

    An efficient method to compute permeability of fibrous media is presented. An immersed domain approach is used to represent the porous material at its microscopic scale and the flow motion is computed with a stabilized mixed finite element method. Therefore the Stokes equation is solved on the whole domain (including solid part) using a penalty method. The accuracy is controlled by refining the mesh around the solid-fluid interface defined by a level set function. Using homogenisation techniques, the permeability of a representative elementary volume (REV) is computed. The computed permeabilities of regular fibre packings are compared to classical analytical relations found in the bibliography.

    The crack tensor model which is a kind of equivalent continuum model has been studied in rock mechanical investigation in the MIU. The fractured rock mass is modeled as the elastic continuum model with this crack tensor. In this study, this crack tensor based on the geological observation in the MIU project was calculated, and Representative Elementary Volume (REV) in the ventilation shaft and -300 m access/research gallery was studied based on the relative error of this crack tensor. As a result, the convergence of the relative error was faster in the -300 m access/research gallery than in the ventilation shaft. (author)

  6. High amplitude phase resetting in rev-erbalpha/per1 double mutant mice.

    Directory of Open Access Journals (Sweden)

    Corinne Jud

    Full Text Available Over time, organisms developed various strategies to adapt to their environment. Circadian clocks are thought to have evolved to adjust to the predictable rhythms of the light-dark cycle caused by the rotation of the Earth around its own axis. The rhythms these clocks generate persist even in the absence of environmental cues with a period of about 24 hours. To tick in time, they continuously synchronize themselves to the prevailing photoperiod by appropriate phase shifts. In this study, we disrupted two molecular components of the mammalian circadian oscillator, Rev-Erbalpha and Period1 (Per1. We found that mice lacking these genes displayed robust circadian rhythms with significantly shorter periods under constant darkness conditions. Strikingly, they showed high amplitude resetting in response to a brief light pulse at the end of their subjective night phase, which is rare in mammals. Surprisingly, Cry1, a clock component not inducible by light in mammals, became slightly inducible in these mice. Taken together, Rev-Erbalpha and Per1 may be part of a mechanism preventing drastic phase shifts in mammals.

  7. Validation of CATHENA MOD-3.5/Rev0 for single-phase water hammer

    Beuthe, T.G.

    2000-01-01

    This paper describes work performed to validate the system thermalhydraulics code CATHENA MOD-3.5c/Rev0 for single-phase water hammer. Simulations were performed and are compared quantitatively against numerical tests and experimental results from the Seven Sisters Water Hammer Facility to demonstrate CATHENA can predict the creation and propagation of pressure waves when valves are opened and closed. Simulations were also performed to show CATHENA can model the behaviour of reflected and transmitted pressure waves at area changes, dead ends, tanks, boundary conditions, and orifices in simple and more complex piping systems. The CATHENA results are shown to calculate pressure and wave propagation speeds to within 0.2% and 0.5% respectively for numerical tests and within 3.3% and 5% for experimental results respectively. These results are used to help validate CATHENA for use in single-phase water hammer analysis. They also provide assurance that the fundamental parameters needed to successfully model more complex forms of water hammer are accounted for in the MOD-3.5c/Rev0 version of CATHENA, and represent the first step in the process to validate the code for use in modelling two-phase water hammer and condensation-induced water hammer.

    TRRS(rev. 1), on-line Technical Reports Retrieval System, a set of computer programs, was designed and developed to provide fast and efficient access to computer-based information files. This system was foucused upon its application to the retrival of technical reports collected in KAERI, and developed not only to meet the requirements of researchers sitting at terminal but to accomodate its sufficiently general logic to other computer systems. The retrival program language is FORTRAN IV Plus. The users can search the whole files using next eleven TRRS(rev. 1) commands, HELP, SEARCH, LOOK, COMBINE, EXPAND, SELECT, REVIEW, RESTART, TYPE, PRINT, and END. The special features of this system are as follows. First, the SEARCH command can process full and truncation (truncation mark is %), and can combine such truncated terms using Boolean operators, and (*), and and-not (.). Second, COMBINE command can combine set numbers with year(s), language(s) and a substring of titles. Third, after EXPAND command, either full or truncated term, SELECT command brings same result of SEARCH command. Finally, real time response is very short, real time response is very short, usually within a second or less. (Author)

    The fast reactor 70-group constant set JFS-3-J3T has been generated by using the JENDL-3T nuclear data. One-dimensional 21-benchmark cores and the ZPPR-9 core were analysed with the JFS-3-J3T set. The results obtained are summarized as follows: (1) The values of keff are underestimated by 0.6% for Pu-fueled cores and overestimated by 2% for U-fueled cores. (2) The central reaction rate ratio 239 σ f φ/ 235 σ f φ is in a good agreement with the experimental value, though 238 σ c φ/ 239 σ f φ and 238 σ f φ/ 235 σ f φ are overestimated. (3) Doppler and Na-void reactivities are in a good agreement with the measured data. (4) The prediction accuracy of radial reaction rate distributions are improved in the comparison of the results obtained with the JENDL-2 data. Furthermore, the benchmark test of JENDL-3T/Rev. 1 which was revised from JENDL-3T for several important nuclides has been again performed. It was shown that JENDL-3T/Rev. 1 would predict nuclear characteristics more satisfactorily than JENDL-3T. (author)

    Full Text Available Heme is a ligand for the human nuclear receptors (NR REV-ERBalpha and REV-ERBbeta, which are transcriptional repressors that play important roles in circadian rhythm, lipid and glucose metabolism, and diseases such as diabetes, atherosclerosis, inflammation, and cancer. Here we show that transcription repression mediated by heme-bound REV-ERBs is reversed by the addition of nitric oxide (NO, and that the heme and NO effects are mediated by the C-terminal ligand-binding domain (LBD. A 1.9 A crystal structure of the REV-ERBbeta LBD, in complex with the oxidized Fe(III form of heme, shows that heme binds in a prototypical NR ligand-binding pocket, where the heme iron is coordinately bound by histidine 568 and cysteine 384. Under reducing conditions, spectroscopic studies of the heme-REV-ERBbeta complex reveal that the Fe(II form of the LBD transitions between penta-coordinated and hexa-coordinated structural states, neither of which possess the Cys384 bond observed in the oxidized state. In addition, the Fe(II LBD is also able to bind either NO or CO, revealing a total of at least six structural states of the protein. The binding of known co-repressors is shown to be highly dependent upon these various liganded states. REV-ERBs are thus highly dynamic receptors that are responsive not only to heme, but also to redox and gas. Taken together, these findings suggest new mechanisms for the systemic coordination of molecular clocks and metabolism. They also raise the possibility for gas-based therapies for the many disorders associated with REV-ERB biological functions.

    Despite the solid connection between REV-ERB and obesity, the information about whether genetic variations at this locus may be associated with obesity traits is scarce. Therefore our objective was to study the association between REV-ERB-ALPHA1 rs2314339 and obesity in two independent populations. Participants were 2214 subjects from Spanish Mediterranean (n = 1404) and North American (n = 810) populations. Anthropometric, biochemical, dietary, and genotype analyses were performed. We found novel associations between the REV-ERB-ALPHA1 rs2314339 genotype and obesity in two independent populations: in Spanish Mediterranean and North American groups, the frequency of the minor-allele-carriers (AA+ AG) was significantly lower in the "abdominally obese" group than in those of the "nonabdominally obese" group (p obesity than noncarriers, and the effect was of similar magnitude for both populations (OR ≈ 1.50). There were consistent associations between REV-ERB-ALPHA1 genotype and obesity-related traits (p obesity was also detected in the Mediterranean population. This new discovery highlights the importance of REV-ERB-ALPHA1 in obesity and provides evidence for the connection between our biological clock and obesity-related traits. © 2013 WILEY-VCH Verlag GmbH & Co.

    We comment on the paper by Van Gorder [“Motion of a helical vortex filament in superfluid 4 He under the extrinsic form of the local induction approximation,” Phys. Fluids 25, 085101 (2013)]. We point out that the flow of the normal fluid component parallel to the vortex will often lead into the Donnelly–Glaberson instability, which will cause the amplification of the Kelvin wave. We explain why the comparison to local nonlinear equation is unreasonable, and remark that neglecting the motion in the x-direction is not reasonable for a Kelvin wave with an arbitrary wavelength and amplitude. The correct equations in the general case are also derived

    We update our earlier study [Phys. Lett. B 544 (2002) 239], which was inspired by the 2002 SNO data, on the implications of the results of the solar neutrino experiments for the predictions of the effective Majorana mass in neutrinoless double beta-decay, vertical bar vertical bar. We obtain predictions for vertical bar vertical bar using the values of the neutrino oscillation parameters, obtained in the analyzes of the presently available solar neutrino data, including the just published data from the salt phase of the SNO experiment, the atmospheric neutrino and CHOOZ data and the first data from the KamLAND experiment. The main conclusion reached in the previous study [Phys. Lett. B 544 (2002) 239] of the existence of significant lower bounds on vertical bar vertical bar in the cases of neutrino mass spectrum of inverted hierarchical (IH) and quasi-degenerate (QD) type is strongly reinforced by fact that combined solar neutrino data (i) exclude the possibility of cos2θ o =0 at more than 5 s.d., (ii) determine as a best fit value cos2θ o =0.40, and (iii) imply at 95% C.L. that cos2θ o ∼>0.22, θ o being the solar neutrino mixing angle. For the IH and QD spectra we get using, e.g., the 90% C.L. allowed ranges of values of the oscillation parameters, vertical bar vertical bar ∼>0.010 eV and vertical bar vertical bar ∼>0.043 eV, respectively. We also comment on the possibility to get information on the neutrino mass spectrum and on the CP-violation in the lepton sector due to Majorana CP-violating phases

    This work deals with numerical simulation of powder caking process caused by capillary condensation phenomenon. Caking consists in unwanted agglomeration of powder particles. This process is often irreversible and not easy to predict. To reproduce mechanism involved by caking phenomenon we have used the Discrete Elements Method (DEM). In the present work, we mainly focus on the role of capillary condensation and subsequent liquid bridge formation within a granular medium exposed to fluctuations of ambient relative humidity. Such bridges cause an attractive force between particles, leading to the formation of a cake with intrinsic physicochemical and mechanical properties. By considering a Representative Elementary Volume (REV), the DEM is then performed by means of a MULTICOR-3D software tacking into account the properties of the cake (degree of saturation) in order to establish relationships between the microscopic parameters and the macroscopic behaviour (tensile strength).

  8. Functional analysis of the interaction of the human immunodeficiency virus type 1 Rev nuclear export signal with its cofactors

    Human immunodeficiency virus type 1 (HIV-1) Rev-mediated nuclear export of viral RNAs involves the interaction of its leucine-rich nuclear export sequence (NES) with nuclear cofactors. In yeast two-hybrid screens of a human lymph node derived cDNA expression library, we identified the human nucleoporin Nup98 as a highly specific and potent interactor of the Rev NES. Using an extensive panel of nuclear export positive and negative mutants of the functionally homologous NESs of the HIV-1 Rev, human T cell leukemia virus type 1 (HTLV-1) Rex, and equine infectious anemia virus (EIAV) Rev proteins, physiologically significant interaction of hNup98 with the various NESs was demonstrated. Missense mutations in the yeast nuclear export factor Crm1p that abrogated Rev NES interaction with the XXFG repeat-containing nucleoporin, Rab/hRIP, had minimal effects on the interaction of GLFG repeat-containing hNup98. Functional analysis of Nup98 domains required for nuclear localization demonstrated that the entire ORF was required for efficient incorporation into the nuclear envelope. A putative nuclear localization signal was identified downstream of the GLFG repeat region. Whereas overexpression of both full-length Nup98 and the amino-terminal GLFG repeat region, but not the unique carboxy-terminal region, induced significant suppression of HIV unspliced RNA export, lower levels of exogenous Nup98 expression resulted in a relatively modest increase in unspliced RNA export. These results suggest a physiological role for hNup98 in modulating Rev-dependent RNA export during HIV infection

    The HIV Rev protein mediates the transport of partially and unspliced HIV mRNA from the nucleus to the cytoplasm. Rev multimerizes on a secondary stem-loop structure present in the viral intron-containing mRNA species and recruits the cellular karyopherin CRM1 to export viral mRNAs from the nucleus to the cytoplasm. Previously we have identified a single-domain intrabody (Nb(190)), derived from a llama heavy-chain antibody, which efficiently inhibits Rev multimerization and suppresses the production of infectious virus. We recently mapped the epitope of this nanobody and demonstrated that Rev residues K20 and Y23 are crucial for interaction while residues V16, H53 and L60 are important to a lesser extent. Here, we generated cell lines stably expressing Nb(190) and assessed the capacity of these cell lines to suppress the replication of different HIV-1 subtypes. These cells stably expressing the single-domain antibody are protected from virus-induced cytopathogenic effect even in the context of high multiplicity of infection. In addition, the replication of different subtypes of group M and one strain of group O is significantly suppressed in these cell lines. Next, we analysed the natural variations of Rev amino acids in sequence samples from HIV-1 infected patients worldwide and assessed the effect of Nb(190) on the most prevalent polymorphisms occurring at the key epitope positions (K20 and Y23) in Rev. We found that Nb(190) was able to suppress the function of these Rev variants except for the K20N mutant, which was present in only 0.7% of HIV-1 sequence populations (n = 4632). Cells stably expressing the single-domain intrabody Nb(190) are protected against virus-induced cytopathogenic effect and display a selective survival advantage upon infection. In addition, Nb(190) suppresses the replication of a wide range of different HIV-1 subtypes. Large-scale sequence analysis reveals that the Nb(190) epitope positions in Rev are well conserved across major HIV-1

  11. Persistence of attenuated HIV-1 rev alleles in an epidemiologically linked cohort of long-term survivors infected with nef-deleted virus

    Directory of Open Access Journals (Sweden)

    Wesselingh Steven L

    2007-07-01

    Full Text Available Abstract Background The Sydney blood bank cohort (SBBC of long-term survivors consists of multiple individuals infected with nef-deleted, attenuated strains of human immunodeficiency virus type 1 (HIV-1. Although the cohort members have experienced differing clinical courses and now comprise slow progressors (SP as well as long-term nonprogressors (LTNP, longitudinal analysis of nef/long-terminal repeat (LTR sequences demonstrated convergent nef/LTR sequence evolution in SBBC SP and LTNP. Thus, the in vivo pathogenicity of attenuated HIV-1 strains harboured by SBBC members is dictated by factors other than nef/LTR. Therefore, to determine whether defects in other viral genes contribute to attenuation of these HIV-1 strains, we characterized dominant HIV-1 rev alleles that persisted in 4 SBBC subjects; C18, C64, C98 and D36. Results The ability of Rev derived from D36 and C64 to bind the Rev responsive element (RRE in RNA binding assays was reduced by approximately 90% compared to Rev derived from HIV-1NL4-3, C18 or C98. D36 Rev also had a 50–60% reduction in ability to express Rev-dependent reporter constructs in mammalian cells. In contrast, C64 Rev had only marginally decreased Rev function despite attenuated RRE binding. In D36 and C64, attenuated RRE binding was associated with rare amino acid changes at 3 highly conserved residues; Gln to Pro at position 74 immediately N-terminal to the Rev activation domain, and Val to Leu and Ser to Pro at positions 104 and 106 at the Rev C-terminus, respectively. In D36, reduced Rev function was mapped to an unusual 13 amino acid extension at the Rev C-terminus. Conclusion These findings provide new genetic and mechanistic insights important for Rev function, and suggest that Rev function, not Rev/RRE binding may be rate limiting for HIV-1 replication. In addition, attenuated rev alleles may contribute to viral attenuation and long-term survival of HIV-1 infection in a subset of SBBC members.

  12. Analysis of translesion DNA synthesis activity of the human REV1 protein, which is a key player in radiation-induced mutagenesis

    International Nuclear Information System (INIS)

    Masuda, Yuji; Kamiya, Kenji

    2003-01-01

    Ionizing radiation frequently causes oxidative DNA damage in cells. It has been suggested that functions of the REV1 gene are induction of mutations and prevention of cell death caused by ionizing radiation through the damage bypass DNA replication. The gene product possesses a deoxycytidyl transferase activity, which is required for translesion DNA synthesis of a variety of damaged bases and an abasic site. To elucidate molecular mechanisms of the mutagenesis and translesion DNA synthesis, it is important to characterize the enzymatic properties of the REV1 protein. Here, we describe a novel method for purifying the recombinant human REV1 protein and the anzymatic properties of the protein. We established an efficient system for induction of the recombinant human REV1 protein in Escherichia coli cells. The REV1 protein was purified to homogeneity using nickel-chelating sepharose, heparin sepharose and superdex 200 chromatography. When purified by this method, REV1 protein is free of endo-, exonuclease and DNA polymerase activities. The purified REV1 protein is suitable for enzymological studies, and we used this to biochemical characterization. The REV1 protein inserts dCMP opposite templates G, A, T, C and an abasic site and inserts dGMP and dTMP opposite template G. Kinetic analysis provided evidence for high efficiency for dCMP insertion opposite template G and an abasic site, suggesting that the REV1 protein play a role in translesion DNA synthesis of an abasic site.

    The purpose of this papers to present the results of CB3 phase of the VVER calculational benchmark with the recent evaluated nuclear data library ENDF/B-VI Rev.5 (1999). This results are compared with the obtained from the other participants in the calculations (Czech Republic, Finland, Hungary, Slovaquia, Spain and the United Kingdom). The phase (CB3) of the VVER calculation benchmark is similar to the Phase II-A of the OECD/NEA/INSC BUC Working Group benchmark for PWR. The cases without burnup profile (BP) were performed with the WIMS/D-4 code. The rest of the cases have been carried with DOTIII discrete ordinates code. The neutron library used was the ENDF/B-VI rev. 5 (1999). The WIMS/D-4 (69 groups) is used to collapse cross sections from the ENDF/B-VI Rev. 5 (1999) to 36 groups working library for 2-D calculations. This work also comprises the results of CB1 (obtained with ENDF/B-VI rev. 5 (1999), too) and CB3 for cases with Burnup of 30 MWd/TU and cooling time of 1 and 5 years and for case with Burnup of 40 MWd/TU and cooling time of 1 year.

    In human astrocytes, restriction of HIV replication involves inhibition of HIV Rev activity. We previously identified a Rev-interacting human protein fragment (16.4.1) that can reduce Rev activity. The 16.4.1 sequence is contained in a group of highly similar host cell proteins, which we call the Risp family. Here we investigate whether the Risp family is connected to HIV replication in astrocytes. Cell/tissue lysates were analyzed for Risp expression by western blot with various anti-Risp antibodies. The interaction of astrocytic Risp members with Rev was investigated by affinity chromatography. Astrocytes were transfected with expression plasmids containing cDNAs encoding full-length Risp or the isolated 16.4.1 region for Risp overexpression or with siRNAs designed for Risp knock-down. Rev activity was investigated with a Rev-reporter assay. RNA levels were quantified by real-time RT-PCR, HIV Gag levels by p24ELISA. Expression of the Risp family was demonstrated in human brain tissues and astrocytes. Astrocytes were shown to produce Risp family members that interact with Rev. Production of HIV Gag proteins and Rev-dependent RNAs in persistently infected astrocytes increased upon Risp knock-down and decreased upon Risp overexpression. Risp knock-down increased Rev activity and raised proportions of Rev proteins in the nucleus of astrocytes. Our results link the Risp family to restriction of HIV production and inhibition of Rev activity in astrocytes. We conclude that the Risp family represents a novel family of host factors that can control HIV replication and may be important for the containment of HIV infection in brain reservoirs.

    Full Text Available For the problem of whether the representative elementary volume (REV obtained in the Darcy flow is also applicable to the case of the non-Darcy flow, the study on the REV size within the non-Darcy flow is proposed tentatively. The concept of the REV in the non-Darcy flow is based on the definition of the REV. According to the determination of the REV in the Darcy flow, the intrinsic permeability k and non-Darcy coefficient β are used simultaneously for the determination of the REV in the non-Darcy flow. The pore pressure cohesive element (PPCE is developed with the subroutine in ABAQUS. Then the simulation method of the Darcy and non-Darcy flow in the fractured rock mass is built using the PPCE. The proposed plan is examined through the comparison with existing research results. It is validated that this technic is efficient and accurate in simulating the Darcy and non-Darcy flow in the fractured rock mass. Combined with fracture networks generated by Monte Carlo Simulation technique, the PPCE is applied to the study on the REV size. Both conditions of the Darcy and non-Darcy flow are simulated for comparison. The simulation results of this model show that the REV of the non-Darcy flow is inconsistent with the REV of the Darcy flow, and the REV of the non-Darcy flow is more significant than the REV of the Darcy flow. The intrinsic permeability k tensors obtained in the Darcy flow and the non-Darcy flow are basically the same.

    Full Text Available Cynodon dactylon is used in Iranian traditional medicine as a healing agent for reducing the complications of diabetes mellitus. We proposed that Cynodon dactylon may perform its effects through moderating humoral and cellular immune responses. We aimed to determine the possible effects of hydroalcholic extract of Cynodon dactylonon humoral and cellular immune responses following the Rev1 challenge in the mouse model. 20 NMRI male mice were randomly grouped in two equal groups and immunized with Rev1[0.1 ml Rev1+0.9 PBS[. Mice in the treatment group orally received 400 mg/kg hydroalcoholic extract of Cynodon dactylon every day from the beginning of the study for 2 weeks. Blood samples were obtained from the animals 5 days after the last injection. Moreover, 48 hr before bleeding time, Rev1[0.1 ml Rev1+0.9 PBS[was injected into the left hind foot pad of mice. The levels of anti-Rev1 antibody and the specific cellular immune responses were measured by microhemagglutination test and footpad thickness, respectively. Moreover, susceptibility of macrophages respiratory burst and proliferation of immune cells were measured in order withNitroblue tetrazolium[NBT] and Microculture Tetrazolium Assay [MTT]. The concentrations of IL-1, TNFα, Il-6, and IL-10 in the serum were determined using commercially available ELISA kits. We found a significant increase in anti-Rev1 antibody levels and simultaneously a significant decrease in the level of cellular immunity[DTH] in the treatment group compared to the control group. Lymphocyte proliferation index in splenocytes was significantly increased in the treatment group. However, the level of respiratory burst in phagocytic population of splenocytes dramatically decreased in the treatment group compared to the control. A significant decrease in IL-6, TNF-α , IL-1 and increaseIl-10 serum levels were also seen in the treatment group. Cynodon dactylon extract could have an anti-inflammatory effect through

    ELSAM and ELTRA have established an offshore wind farm with an output of 160 MW in the waters of Horns Rev 1420 km off Blaevands Huk, which is the most westerly point of Denmark. The first phase of construction of the wind farm started in spring 2002. Before the construction activities took place, a baseline description of the benthos was conducted as a part of an environmental monitoring programme for the establishment of the Horns Rev Offshore Wind Farm. The baseline surveys for the present monitoring programme were conducted in the wind farm area on three occasions: spring 1999, spring 2001 and September 2001. In designated reference areas, surveys were conducted in spring 1999 and September 2001. The reference areas in 1999 and September 2001 were placed at two different geographical locations because the survey in September 2001 was planned to be a part of a fish monitoring programme. A comparison between the baseline study in spring 2001 and the baseline study in autumn 2001 clearly revealed that the biomass of most species increased considerably from spring to September. Despite the increase in biomass, the overall distribution of the species and their relative abundance did not change. In order to use the baseline data to investigate a possible impact after the construction of the wind farm, it was essential to arrange the monitoring programme either in spring or in September 2003, because the baseline studies were conducted in these periods. The monitoring programme was conducted in September 2003 after the wind farm had become operational, parallel with the survey on hard bottom substrates. The impacts of the wind farm on the benthic fauna (infauna) in the area were mainly expected to be due to the alteration of the local currents. As the changes in the currents are only minor, impacts on the water chemistry and on the benthic fauna resulting from hydrodynamic causes were expected to be limited or non-existent.

    A total of 40 species were identified from the surveys in the Horns Rev area in September 2004 while 42 species were identified in 2003 and 47 species in September 2001. The decline in the number of species occurred both inside the wind farm and reference areas, which indicates that the decline could be a combination of changes in sediment characteristics and natural variation rather than an effect from the establishment of the wind farm. More species were not associated with the hard substrate at the turbine sites in 2004 compared to 2003, while in 2001, more species were associated with fine-grained sand. The median sediment grain size increased from 2001 to 2003 to 2004, which suggests that the velocity of the current increased, but modelling calculations on current speed predicted a 2% reduction in the wind farm area and up to a 15% reduction very close to the scour protection. These results agreed with the grain sizes found at the stations 5, 25 and 100 metres from the scour protection. At most stations, the medium grain size was 5 metres lower from the scour protection compared with the station 100 metres from the scour protection, which indicates that the velocity of the current was lower close to the scour protection. No significant impact on the infauna in the wind farm area was detectable concerning distance-related effects. Though general reductions in the population size of some of the character species in the surveyed areas might be related to changes in the sediment structure, the infauna community at Horns Rev showed no obvious sign of stress response as a consequence of possible impact from construction and operating activities. New species were observed in 2003 and 2004 and some of these might be a result of sediment characteristics, less predation or natural variation. The recording of other species might be a result of the introduction of hard bottom habitants in the wind farm area. The density of the most abundant bivalves and bristle worms was

    2000-05-01

    As part of an overall Environmental Impact Assessment (EIA) undertaken in connection with a planned 150 MW offshore wind farm at Horns Rev, an assessment was made of the effects the wind farm would have on the water quality in the area. This EIA study was drawn up in accordance with the guidelines laid down by the Danish Ministry of Environment and Energy in the publication 'Guidelines for the preparation of EIA studies for offshore wind farms'. Horns Rev is situated off Blaevands Huk, which is Denmark's most westerly point. It is a shallow reef with water depths between 2 and 9 metres and is primarily composed of sand, gravel and pebbles. Only local and minor changes are anticipated in connection with the currents, sediments and wave conditions during the production phase. These will occur in the immediate vicinity of the individual foundations. For these reasons, no changes are expected in the water quality. This also includes also the pelagic primary production and the occurrence of plankton in the area. Increased local copper contamination of phytoplankton and zooplankton may be expected during the production phase, as a result of the total annual discharge of 206 kg copper from the slip-rings in the wind turbines. The contamination will potentially result in a local reduction of the pelagic primary production and changes in the species composition of the plankton. The wind turbines will be sandblasted and painted once during their lifetime, as part of the routine maintenance. The sandblasting and painting will lead to a temporary spill of paint, paint waste and sand. The impacts on water quality and plankton production are unknown. It is recommended that factors such as the toxicity of the paint be investigated, and that spills and the impact of waste be reduced as much as possible. The water quality and the plankton in the wind farm area and along the cable line's passage to shore through the international protected area, will only be affected in a minor way

    In the recently published paper “Magnetic geometry and physics of advanced divertors: The X-divertor and the snowflake” [Phys. Plasmas 20, 102507 (2013)], the authors raise interesting and important issues concerning divertor physics and design. However, the paper contains significant errors: (a) The conceptual framework used in it for the evaluation of divertor “quality” is reduced to the assessment of the magnetic field structure in the outer Scrape-Off Layer. This framework is incorrect because processes affecting the pedestal, the private flux region and all of the divertor legs (four, in the case of a snowflake) are an inseparable part of divertor operation. (b) The concept of the divertor index focuses on only one feature of the magnetic field structure and can be quite misleading when applied to divertor design. (c) The suggestion to rename the divertor configurations experimentally realized on NSTX (National Spherical Torus Experiment) and DIII-D (Doublet III-D) from snowflakes to X-divertors is not justified: it is not based on comparison of these configurations with the prototypical X-divertor, and it ignores the fact that the NSTX and DIII-D poloidal magnetic field geometries fit very well into the snowflake “two-null” prescription

    2003-07-01

    This report presents data from six aerial surveys of birds in the Horns Rev wind farm area in 2003. Including 16 surveys conducted before construction of the wind farm started and three during the construction phase, a total of 25 surveys have been performed in the area since August 1999. Up until August 2002 the study area was surveyed from 26 north-south oriented, parallel transect lines. After that time four short transects were added eastwards from the previously easternmost transect. From August 2002 slight adjustments to the transect lines in the wind farm area had to be made in order to avoid collision, as survey altitude was 76 m and wind turbines are 110 m to highest wing tip. The six surveys in 2003 were performed on 13 February, 16 March, 23 April, 5 September, 4 and 30 December. The operational phase of the wind farm commenced in 2002. Hence the six surveys from 2003 are all considered post-construction data sets. A preliminary evaluation of the potential impact of the wind turbines on bird distributions has been carried out by comparison of these data to those from the 16 pre-construction surveys. (au)

    Computational analysis of feline immunodeficiency virus (FIV) RNA sequences indicated that common FIV strains contain a rev response element (RRE) defined by a long unbranched hairpin with 6 stem-loop sub-domains, termed stem-loop A (SLA). To examine the role of the RNA secondary structure of the RRE, mutational analyses were performed in both an infectious FIV molecular clone and a FIV CAT-RRE reporter system. These studies disclosed that the stems within SLA (SA1, 2, 3, 4, and 5) of the RRE were critical but SA6 was not essential for FIV replication and CAT expression. These studies also revealed that the secondary structure rather than an antisense protein (ASP) mediates virus expression and replication in vitro. In addition, a single synonymous mutation within the FIV-RRE, SA3/45, reduced viral reverse transcriptase activity and p24 expression after transfection but in addition also showed a marked reduction in viral expression and production following infection.

    Energy Technology Data Exchange (ETDEWEB)

    The wind farm output of an offshore-farm such as Horns Rev changes between nearly constant output to highly variable power output. A balance responsible will therefore benefit from knowing the variability of a wind farm in advance. Some understanding of the observed variability and the corresponding forecast error on offshore wind farms had been gathered in the past few years, while a large fraction (about 60%) of the error still lacked understanding and required further intense research. This was the outset at the beginning of the HREnsemble project. Results from the wave study, variability study, ocean coupling, findings from the sensitivity experiments, the iEnKF short-term forecast and finally the demonstration phase have given significant synergy. The most basic research result in the project is that the two empirical mode decomposition approaches, Hilbert-Huang and later the Ensemble Empirical Mode Decomposition (EEMD). Both approaches confirmed that significant variability exists in offshore conditions. It was found that the variability of the short time-scales (24 minutes) are either not explicitly visible in the grid-scale of the NWP models or in the best case significantly smoothed out in all of the tested model configurations. If we interpret 2/3 of the variability due to vertical waves not present in the mean flow and 1/3 of the variability due to meso-scale weather, then the model results and EEMD are consistent. We can however not verify this theory. At present we do not know if EEMD counts neither the events correct nor whether the ensemble forecast suppresses variability. The existence of variability above the time-scale related to friction between ocean waves and air can in fact explain some of the inconsistent results published in the literature and set a question mark behind the correctness of the calculation of friction in wave, ocean and weather modelling.

    Classic nuclear export signals (NESs) confer CRM1-dependent nuclear export. Here we present crystal structures of the RanGTP-CRM1 complex alone and bound to the prototypic PKI or HIV-1 Rev NESs. These NESs differ markedly in the spacing of their key hydrophobic (Φ) residues, yet CRM1 recognizes them with the same rigid set of five Φ pockets. The different Φ spacings are compensated for by different conformations of the bound NESs: in the case of PKI, an α-helical conformation, and in the case of Rev, an extended conformation with a critical proline docking into a Φ pocket. NMR analyses of CRM1-bound and CRM1-free PKI NES suggest that CRM1 selects NES conformers that pre-exist in solution. Our data lead to a new structure-based NES consensus, and explain why NESs differ in their affinities for CRM1 and why supraphysiological NESs bind the exportin so tightly.

    The development of offshore wind power results in more energy production per area unit and new requirements to the generation forecasts. Measurements from Horns Rev and ensemble forecasts were used to upgrade forecasting tools for the relevant periods and time scales. The most significant development is a new algorithm for short-term forecasts that combines any relevant online measurements by means of ensemble forecasts. (ln)

    Full Text Available La evaluación de las competencias o cualidades humanas que cada aprendiz ha de desarrollar de manera singular para afrontar la complejidad de la era digital contemporánea es incompatible con las reválidas, test y pruebas externas estandarizadas, iguales para todos. Las cualidades más importantes del aprendizaje en la era digital —autodirección, iniciativa, creatividad, pensamiento crítico, solución de problemas y autoevaluación— son difícilmente evaluables mediante instrumentos baratos y masivos «de papel y lápiz», como los test estandarizados o las reválidas externas; requieren, por el contrario, herramientas y procesos más complejos, plurales y flexibles como la observación continua de los equipos docentes sobre el quehacer y los procesos y productos de los aprendices (Soto Gómez, 2014. La LOMCE,1 fiel exponente de la pedagogía conservadora del movimiento GERM,2 recupera las reválidas, pues apuesta por la estandarización de aprendizajes superficiales en lugar de potenciar el desarrollo singular de cada aprendiz hasta el máximo de sus posibilidades.

    Since the September 11 attacks in 2001, counterterrorism measures have become not just domestic issues but critical issues that need international cooperation. Various nuclear security measures are in place as part of international counterterrorism measures. This report looks at the trend of international nuclear security measures to get implications for Japan, focusing on INFCIRC/225/Rev.5, an international guideline for physical protection of nuclear materials and nuclear facilities drawn up by IAEA. The observations of this report are as follows: 1) While legally binding nuclear security measures such as multilateral treaties and United Nations Security Council Resolutions impose minimum requirements on individual countries, the approaches led by IAEA or individual countries or private associations aim at more detailed consideration or information sharing to further improve nuclear security. 2) INFCIRC/225/Rev.5 comprises new concepts such as risk-based physical protection and nuclear security culture, as well as extended range of threats such as insiders or stand-off attacks and broader scope of measures to response. Japan should consider incorporation of INFCIRC/225/Rev.5 to its national laws and regulations putting in mind that it may have heavy influence and that Japan pledged to role leadership about nuclear security to international society.

    Full Text Available Brucellosis is one of the most important zoonotic diseases and is a significant cause of abortion in animals. Brucella melitensis strain Rev. 1 is recommended as the most effective vaccine for small ruminants but the application of full doses in adult animals is restricted. This study was conducted to determine a proper reduced dose of vaccine which confers protection but which is not abortifacient in Iranian fat-tailed sheep. A total of 51 non-vaccinated pregnant ewes were divided into three main groups and several subgroups. Ewes in different groups were vaccinated at different stages of pregnancy and various subgroups were subcutaneously immunised with different quantities of the micro-organism (7.5 × 106, 106, 5 × 105. Ewes again became pregnant a year later and were challenged with the wild-type strain to evaluate the protection conferred. Results revealed that the proportion of vaccination-induced abortions was significantly higher in ewes immunised with 7.5 × 106 Rev. 1 organisms than in those which received 106 or 5 × 105 bacteria. While 80% of non-vaccinated ewes aborted after challenge, none of the vaccinated ewes aborted post-challenge. This study indicated that a reduced dose of Rev. 1 vaccine containing 106 or 5 × 105 live cells could be safely used to induce protection in Iranian fat-tailed sheep at various stages of pregnancy.

    Matrix monotonicity is used to obtain upper bounds on minimum-error distinguishability of arbitrary ensembles of mixed quantum states. This generalizes one direction of a two-sided bound recently obtained by the author [J. Tyson, J. Math. Phys. 50, 032106 (2009)]. It is shown that the previously obtained special case has unique properties.

Plasmas 21, 054701 (2014)], emphasizes a criterion for divertor characterization that was critiqued to be ill posed [M. Kotschenreuther et al., Phys. Plasmas 20, 102507 (2013)]. We find that no substantive physical differences flow from this criteria. However, using these criteria, the successful NSTX experiment by Ryutov et al. [Phys. Plasmas 21, 054701 (2014)] has the coil configuration of an X-divertor (XD), rather than a snowflake (SF). On completing the divertor index (DI) versus distance graph for this NSTX shot (which had an inexplicably missing region), we find that the DI is like an XD for most of the outboard wetted divertor plate. Further, the “proximity condition,” used to define an SF [M. Kotschenreuther et al., Phys. Plasmas 20, 102507 (2013)], does not have a substantive physics basis to override metrics based on flux expansion and line length. Finally, if the criteria of the comment are important, then the results of NSTX-like experiments could have questionable applicability to reactors

    In S. cerevisiae, the REV3 gene, encoding the catalytic subunit of polymerase zeta, is involved in translesion synthesis and required for the production of mutations induced by ultraviolet radiation (UV) photoproducts and other DNA fork-blocking lesions, and for the majority of spontaneous mutations. To determine whether hREV3, the human homolog of yeast REV3, is similarly involved in error-prone translesion synthesis past UV photoproducts and other lesions that block DNA replication, an hREV3 antisense construct under the control of the TetP promoter was transfected into an infinite life span human fibroblast cell strain that expresses a high level of tTAk, the activator of that promoter. Three transfectant strains expressing high levels of hREV3 antisense RNA were identified and compared with their parental cell strain for sensitivity to the cytotoxic and mutagenic effects of UV. The three hREV3 antisense-expressing cell strains were not more sensitive than the parental strain to the cytotoxic effect of UV, but the frequency of mutants induced by UV in their HPRT gene was significantly reduced, i.e. to 14% that of the parent. Two of these hREV3 antisense-expressing cell strains were compared with the parental strain for sensitivity to ({+-})-7{beta},8{alpha}-dihydroxy-9{alpha},10{alpha}-epoxy-7,8,9,10-tetrahydro= benzo[a]pyrene (BPDE). They were not more sensitive than the parent strain to the cytotoxic effect of BPDE, but the frequency of mutants induced was significantly reduced, i.e. in one strain, to 17% that of the parent, and in the other, to 24%. DNA sequencing showed that the kinds of mutations induced by BPDE in the parental and the derivative strains did not differ and were similar to those found previously with finite life span human fibroblasts. The data strongly support the hypothesis that hRev3 plays a critical role in the induction of mutations by UV or BPDE. Because the level of hRev3 protein in human fibroblasts is below the level of antibody

    Under physiological conditions, astrocytes maintain homeostasis in the CNS. Following inflammation and injury to the CNS, however, activated astrocytes produce neurotoxic molecules such as cytokines and chemokines, amplifying the initial molecular-cellular events evoked by inflammation and injury. Nuclear receptors REV-ERBα and REV-ERBβ (REV-ERBs) are crucial in the regulation of inflammation- and metabolism-related gene transcription. The current study sought to elucidate a role of REV-ERBs in rat C6 astroglial cells on the expression of inflammatory molecules following stimulation with the neuroinflammatory cytokine tumor necrosis factor (TNF). Stimulation of C6 cells with TNF (10 ng/ml) significantly increased the mRNA expression of CCL2, interleukin-6 (IL-6), inducible nitric oxide synthase (iNOS), and matrix metalloprotease (MMP)-9, but not fibroblast growth factor-2 (FGF-2), cyclooxygenase-2 (COX-2) and MMP-2. Treatment with either REV-ERB agonists GSK4112 or SR9009 significantly blocked TNF-induced upregulation of CCL2 mRNA and MMP-9 mRNA, but not IL-6 mRNA and iNOS mRNA expression. Furthermore, treatment with RGFP966, a selective histone deacetylase 3 (HDAC3) inhibitor, potently reversed the inhibitory effects of GSK4112 on TNF-induced expression of MMP-9 mRNA, but not CCL2 mRNA. Expression of Rev-erbs mRNA in C6 astroglial cells, primary cultured rat cortical and spinal astrocytes was confirmed by reverse transcription polymerase chain reaction. Together, the findings demonstrate an anti-inflammatory effect, downregulating of MMP-9 and CCL2 transcription, of astroglial REV-ERBs activation through HDAC3-dependent and HDAC3-independent mechanisms. - Highlights: • Rev-erbα mRNA and Rev-erbβ mRNA are expressed in C6 astroglial cells. • TNF increases the expression of CCL2, IL-6, MMP-9 and iNOS mRNA. • REV-ERB activation inhibits CCL2 mRNA and MMP-9 mRNA expression. • HDAC3 activity is involved in the inhibitory effect of REV-ERB on MMP-9 induction.

    As a result of the Danish Government's Energy Plan 21 a target of 5,500 MW wind power is to be erected in Denmark by 2030. 4,000 MW of these are to be placed offshore in special pointed areas with minimal impacts on the environment. In 1998 the Danish Ministry of Environment and Energy ordered two power companies, Elsam and Energi E2, to establish each a demonstration wind farm at one of the five pointed areas. The intention was to follow the environmental impacts from the wind farm and to evaluate the possibility of setting up about 1,500 MW in each area with as little impact on the environment as possible. In 1999 the two power companies were given approval to begin pre-studies of each of the two wind farms and the work on the site construction as well as the environmental impact assessment related hereto was initiated. The authorities made a number of requirements for the EIA surveys according to the EU-directive for preparation of EIA reports. In the summer of 2000 the EIA report with project description was submitted to the authorities and the project was approved in the spring of 2001. During the summer and autumn of 2001 orders were placed for the components for the wind farm, i.e. foundations, towers, wind turbines, cables etc. After having finalised the EIA, monitoring programmes of the wind farms were initiated on basis of the results of the surveys carried out during the EIA. This means that continuous surveys have been implemented for most of the environmental parameters from 1999 and till today. This annual status report for 2001 is to present the results from the annual environmental monitoring programme (the baseline studies) at Horns Rev, which form part of the monitoring programme set up for the Horns Rev project.

    In a comment published several years ago in this journal, Mitra [J. Math. Phys. 50, 042502 (2009)] has claimed to prove that a neutral point particle in general relativity as described by the Schwarzschild metric must have zero gravitational mass, i.e., the mass parameter M0 of a Schwarzschild black hole necessarily vanishes. It is shown that the purported proof is incorrect. The error stems from a basic misunderstanding of the mathematical description of coordinate volume element in a differentiable manifold.

    The knowledge of the free energy of binding of small molecules to a macromolecular target is crucial in drug design as is the ability to predict the functional consequences of binding. We highlight how a molecular dynamics (MD)-based approach can be used to predict the free energy of small molecules, and to provide priorities for the synthesis and the validation via in vitro tests. Here, we study the dynamics and energetics of the nuclear receptor REV-ERBα with its co-repressor NCoR and 35 novel agonists. Our in silico approach combines molecular docking, molecular dynamics (MD), solvent-accessible surface area (SASA) and molecular mechanics poisson boltzmann surface area (MMPBSA) calculations. While docking yielded initial hints on the binding modes, their stability was assessed by MD. The SASA calculations revealed that the presence of the ligand led to a higher exposure of hydrophobic REV-ERB residues for NCoR recruitment. MMPBSA was very successful in ranking ligands by potency in a retrospective and prospective manner. Particularly, the prospective MMPBSA ranking-based validations for four compounds, three predicted to be active and one weakly active, were confirmed experimentally.

  2. REMINDER: Compliance with Operational Circular No. 2 (Rev. 1) on “Conditions of access to the fenced CERN site”

    2012-01-01

    The purpose of Operational Circular No. 2 (Rev. 1) is to contribute to the protection of people and property by defining the conditions of access to the Organization's fenced sites. The behaviours that cannot be tolerated under any circumstances are: use of CERN access cards by people, other than the cardholders themselves, in order to gain access to facilities without having attended the required safety course; speeding, particularly on Route Gregory and Route Weisskopf; driving in and out of the site on the wrong side of the road; parking on spaces set aside for the disabled; nuisance parking, especially in the proximity of the restaurants; dumping of wrecked vehicles. As the aforementioned instances of non-compliance can lead to dangerous situations, the Organization reserves the right to apply the penalties provided for under paragraph 26 of Operational Circular No. 2 (Rev. 1), namely to refuse access to the site to people and/or their vehicles deemed to be in infringement of the circu...

    Full Text Available Concrete diffusivity is a function of its microstructure on many scales, ranging from nanometres to millimetres. Multi-scale techniques are therefore needed to model this parameter. Representative elementary volume (REV, in conjunction with the homogenization principle, is one of the most common multi-scale approaches. This study aimed to establish a procedure for establishing the REV required to determine cement paste diffusivity based on a three-step, numerical-statistical approach. First, several series of 3D cement paste microstructures were generated with HYMOSTRUC3D, a cement hydration and microstructure model, for different volumes of cement paste and w/c ratios ranging from 0.30 to 0.60. Second, the finite element method was used to simulate the diffusion of tritiated water through these microstructures. Effective cement paste diffusivity values for different REVs were obtained by applying Fick’s law. Finally, statistical analysis was used to find the fluctuation in effective diffusivity with cement paste volume, from which the REV was then determined. The conclusion drawn was that the REV for measuring diffusivity in cement paste is 100x100x100 μm3.

    La difusividad del hormigón depende de su microestructura a numerosas escalas, desde nanómetros hasta milímetros, por lo que se precisa de técnicas multiescala para representar este parámetro. Junto con el principio de homogeneización, uno de los métodos multiescala más habituales es el volumen elemental representativo (VER. El objeto de este estudio era establecer un procedimiento que permitiera determinar el VER necesario para calcular la difusividad de la pasta de cemento, basándose en un método numéricoestadístico que consta de tres etapas. Primero, se crearon varias series de microestructuras de pasta de cemento en 3D con HYMOSTRUC3D, un programa que permite crear un modelo de la hidratación y microestructura del cemento.

    Full Text Available Abstract Background The process of HIV-1 genomic RNA (gRNA encapsidation is governed by a number of viral encoded components, most notably the Gag protein and gRNA cis elements in the canonical packaging signal (ψ. Also implicated in encapsidation are cis determinants in the R, U5, and PBS (primer binding site from the 5' untranslated region (UTR. Although conventionally associated with nuclear export of HIV-1 RNA, there is a burgeoning role for the Rev/RRE in the encapsidation process. Pleiotropic effects exhibited by these cis and trans viral components may confound the ability to examine their independent, and combined, impact on encapsidation of RNA into HIV-1 viral particles in their innate viral context. We systematically reconstructed the HIV-1 packaging system in the context of a heterologous murine leukemia virus (MLV vector RNA to elucidate a mechanism in which the Rev/RRE system is central to achieving efficient and specific encapsidation into HIV-1 viral particles. Results We show for the first time that the Rev/RRE system can augment RNA encapsidation independent of all cis elements from the 5' UTR (R, U5, PBS, and ψ. Incorporation of all the 5' UTR cis elements did not enhance RNA encapsidation in the absence of the Rev/RRE system. In fact, we demonstrate that the Rev/RRE system is required for specific and efficient encapsidation commonly associated with the canonical packaging signal. The mechanism of Rev/RRE-mediated encapsidation is not a general phenomenon, since the combination of the Rev/RRE system and 5' UTR cis elements did not enhance encapsidation into MLV-derived viral particles. Lastly, we show that heterologous MLV RNAs conform to transduction properties commonly associated with HIV-1 viral particles, including in vivo transduction of non-dividing cells (i.e. mouse neurons; however, the cDNA forms are episomes predominantly in the 1-LTR circle form. Conclusions Premised on encapsidation of a heterologous RNA into

    Elsam Engineering AS has approved the implementation of a project concerning the registration of fish communities in Horns Rev Offshore Wind Farm with use of hydroacoustic methods. In a joint effort, Bio/consult as, Carl Bro as and SIMRAD AS have monitored the fish communities at Horns Rev Offshore Wind Farm using a new hydroacoustic methodology. The new hydroacoustic technique combines the use of scientific sonar acoustics with GPS to determine the density, diversity and location of fish. The objectives of this project were to test the possibility of using hydroacoustic techniques as alternative methods to traditional techniques to assess the fish assemblage inhabiting offshore wind farms and to investigate the possible effect from the wind farm and hard bottom substrates (turbine foundations) on fish abundance. The field study was carried out October 9-10, 2004 and consisted of four horizontal hydroacoustic survey transects each covering impact and reference areas. Transects were surveyed in order to achieve identical impact and reference transect pairs concerning environment, topography and time correspondence. The hydroacoustic equipment consisted of a SIMRAD EK60/EY60 echo sounder with a split-beam transducer (Simrad ES 120-4x10) mounted on a pan and tilt unit, a transceiver, a laptop extended with a GPS-receiver and additional large external hard discs. The raw data files from EK60 were converted to echogram files suitable for the post processing application, Sonar5-Pro. The Sonar5-Pro software makes it possible to filter out echo detections from the surface and the bottom, as well as perform cross filter detection. The validity of the results using the hydroacoustic method is high due to the cross filtering and single target tracking technique. From the hydroacoustic results, no or very little effect from the wind farm or from hard bottom substrates was found on the fish densities at Horns Rev Wind Farm at the time of the survey.

The method is applied to Lillgrund and Horns Rev-I offshore wind farms and the results are compared...... with TI derived from the meteorological mast, nacelle mounted anemometer on the turbines and estimation based on the standard deviation of power. The results show that the proposed TI estimation method is in the best agreement with the meteorological mast. Therefore, the rotor effective wind speed...... is shown to be applicable for the TI assessment in real-time wind farm calculations under different operational conditions. Furthermore, the TI in the wake is seen to follow the same trend with the estimated wake deficit which enables to quantify the turbulence in terms of the wake loss locally inside...

    The aim of the project is to assess the collision risk between birds and wind turbines at the Horns Rev wind farm. In 2003 the studies focused on describing bird movements in relation to the wind farm and to identify the species-specific behavioural responses towards the wind turbines shown by migrating and staging species. The Horns Rev area lies in a region known to be important for substantial water bird migration as well as holding internationally important numbers of several wintering and staging water bird species.

    In February 1998, the Ministry of the Environment gave Elsam A/S and Eltra A.m.b.a. approval to erect a wind farm, capable of producing 160 MW of electric power, at Horns Rev, west of Blaevandshuk off the west coast of Jutland. Construction activities at Horns Rev started in September 2001 and were finished in summer 2002. The entire project has been organised as a demonstration project to assess the technical, economic and environmental constraints on the future development of electric power production in Danish offshore environments. Within the framework of the environmental programme, bird investigations have been carried out in relation to the risk of collision between birds and wind turbines since 2002. To provide the latest update on the results from the bird investigations, this note presents results compiled during spring 2004 and deals with a preliminary analysis of effects on birds present at Horns Rev during commercial operation of the Horns Rev wind farm. Due to the remoteness of the area it has not been possible to obtain base-line investigation of bird occurrence and behaviour at the wind farm site. (au)

    Rev is an essential HIV-1 regulatory protein which binds to the Rev responsive element (RRE) present within the env gene of HIV-1 RNA genome. This binding facilitates the transport of the RNA to the cytoplasm, which in turn triggers the switch between viral latency and active viral replication. Essential components of this complex have been localized to a minimal arginine rich Rev peptide and stem IIB region of RRE. A synthetic peptide known as RSG-1.2 binds with high binding affinity and specificity to the RRE-IIB than the Rev peptide, however the thermodynamic basis of this specificity has not yet been addressed. The present study aims to probe the thermodynamic origin of this specificity of RSG-1.2 over Rev Peptide for RRE-IIB. The temperature dependent melting studies show that RSG-1.2 binding stabilizes the RRE structure significantly (ΔT(m) = 4.3°C), in contrast to Rev binding. Interestingly the thermodynamic signatures of the binding have also been found to be different for both the peptides. At pH 7.5, RSG-1.2 binds RRE-IIB with a K(a) = 16.2±0.6×10(7) M(-1) where enthalpic change ΔH = -13.9±0.1 kcal/mol is the main driving force with limited unfavorable contribution from entropic change TΔS = -2.8±0.1 kcal/mol. A large part of ΔH may be due to specific stacking between U72 and Arg15. In contrast binding of Rev (K(a) = 3.1±0.4×10(7) M(-1)) is driven mainly by entropy (ΔH = 0 kcal/mol and TΔS = 10.2±0.2 kcal/mol) which arises from major conformational changes in the RNA upon binding.

    2005-03-15

    This annual report presents the work related to the sociological part of the socio-economic project on the local communities' reception of the Horns Rev Offshore Wind Farm, west of Blaavands Huk in Jutland, and the Nysted Offshore Wind Farm, south of Lolland. The project is part of the monitoring programme in connection with the construction of the offshore wind farms. Unlike projects, which examine the impact of the wind farms on nature, the socio-economic project did not start until 2003. The socio-economic project examines the effects on the local communities. Among other things the environmental-economic part of the project examines the preferences of the population in relation to location of the wind farm and the willingness to pay for increasing the distance between the wind farms and the coast. The sociological survey is qualitative. The survey is divided into three phases, as the aim is to investigate the public community's attitude towards the erection of an offshore wind farm before and after the construction of the wind farm. This aim is based on the assumption that attitudes may change once the wind farm is erected and the population has experienced the visibility of the wind farm, etc. The division into phases is as follows: 1) Phase 1 treats the conditions as they were before the erection of Nysted Offshore Wind Farm. 2) Phase 2 is an investigation of the development in attitudes towards Horns Rev Offshore Wind Farm a year after erection. 3) Phase 3 comprises a follow-up investigation of the local area at Nysted Offshore Wind Farm. This annual report treats phases 1 and 2. Phase 1 was carried out in April-August 2003, and the interviews at Nysted were thus made during the erection of the first offshore wind turbines. Phase 2 was carried out in September-November 2003. The follow-up investigation of the conditions in the local area around Nysted offshore wind farm is to be carried out in August-December 2004.

    2009-09-01

    Full Text Available Organisms like Dictyostelium discoideum, often referred to as DNA damage "extremophiles", can survive exposure to extremely high doses of radiation and DNA crosslinking agents. These agents form highly toxic DNA crosslinks that cause extensive DNA damage. However, little is known about how Dictyostelium and the other "extremophiles" can tolerate and repair such large numbers of DNA crosslinks. Here we describe a comprehensive genetic analysis of crosslink repair in Dictyostelium discoideum. We analyse three gene groups that are crucial for a replication-coupled repair process that removes DNA crosslinks in higher eukarya: The Fanconi anaemia pathway (FA, translesion synthesis (TLS, and nucleotide excision repair. Gene disruption studies unexpectedly reveal that the FA genes and the TLS enzyme Rev3 play minor roles in tolerance to crosslinks in Dictyostelium. However, disruption of the Xpf nuclease subcomponent results in striking hypersensitivity to crosslinks. Genetic interaction studies reveal that although Xpf functions with FA and TLS gene products, most Xpf mediated repair is independent of these two gene groups. These results suggest that Dictyostelium utilises a distinct Xpf nuclease-mediated repair process to remove crosslinked DNA. Other DNA damage-resistant organisms and chemoresistant cancer cells might adopt a similar strategy to develop resistance to DNA crosslinking agents.

    The Ministry of Environment and Energy requested ELSAM and ELTRA to establish an offshore wind farm with an output of 150 MW in the waters of Horns Rev, approximately 15 km off Blaevandshuk, which is the most westerly point of Denmark. The first phase of construction of the wind farm have started in spring 2002. Before the construction activities take place, a baseline description of the benthos has been conducted as a part of an environmental monitoring programme for the introduction of hard bottom substrates in the North Sea. The establishment of a monitoring programme is required according to some environmental guidelines for offshore wind farms prepared by the Danish Energy Agency. The monitoring programme established for the benthic infauna was performed in spring 2001. In addition to a proposed fish investigation programme concerning the stomach contents of fish a comparative programme on benthos was established as part of the monitoring programme. The benthos sampling in connection with the fish programme was conducted in autumn 2001. This benthic survey includes sampling in a proposed reference area for the fish surveys north east of the wind farm. This report presents the data of the baseline environmental survey of the seabed in the wind farm site and in the proposed reference site and a brief description of the weather conditions at the time of sampling.

    The resin infusion process (RIP) has developed as a low cost method for manufacturing large fibre reinforced plastic parts. However, the process still presents some challenges to industry with regards to reliability and repeatability, resulting in expensive and inefficient trial and error development. In this paper, we show the implementation of 2D numerical models for the RIP using the open source simulator DuMu{sup X}. The idea of this study is to present a model which accounts for the interfacial forces coming from the capillary pressure on the so-called representative elementary volume (REV) scale. The model is described in detail and three different test cases — a constant and a tensorial permeability as well as a preform/Balsa domain — are investigated. The results show that the developed model is very applicable for the RIP for manufacturing of composite parts. The idea behind this study is to test the developed model for later use in a real application, in which the preform medium has numerous layers with different material properties.

    Laboratory exercise is helpful for medical students to understand the basic principles of molecular biology and to learn about the practical applications of molecular biology. We have designed a lab course on molecular biology about the determination of single nucleotide polymorphism (SNP) in human REV3 gene, the product of which is a subunit of DNA polymerase ζ and SNPs in this gene are associated with altered susceptibility to cancer. This newly designed experiment is composed of three parts, including genomic DNA extraction, gene amplification by PCR, and genotyping by RFLP. By combining these activities, the students are not only able to learn a series of biotechniques in molecular biology, but also acquire the ability to link the learned knowledge with practical applications. This comprehensive experiment will help the medical students improve the conceptual understanding of SNP and the technical understanding of SNP detection. © 2017 by The International Union of Biochemistry and Molecular Biology, 45(4):299-304, 2017. © 2017 The International Union of Biochemistry and Molecular Biology.

    The program InvMass has been developed to perform a general model-independent search for new particles using the ATLAS detector at the Large Hadron Collider (LHC), a proton-proton collider at CERN. The search is performed by examining statistically significant variations from the Standard Model predictions in exclusive event classes classified according to the number of identified objects. The program, called InvMass, finds all relevant particle groups identified with the ATLAS detector and analyzes their production rates, invariant masses and the total transverse momenta. The generic code of InvMass can easily be adapted for any particle types identified with the ATLAS detector. Several benchmark tests are presented.

    This report presents the combined results of two years of base-line investigations of birds performed during August 1999 - April 2001 in relation to the proposed construction of an offshore wind farm at Horns Rev in the Danish part of the North Sea ca 14 km southwest of Blaevandshuk. Based on the distribution of the most abundant bird species recorded during 13 aerial surveys, there were no indications that the wind farm area was of any particular importance to the birds' exploitation of the Horns Rev area. Fish-eating species like divers, gannet, terns, auks and gulls generally showed scattered and variable distributions, occurring in the areas north and south of Horns Rev, and with low numbers occurring on the reef proper and within the planned wind farm area. The distribution of benthic foraging species, eider and common scoter, showed that they mainly exploited the coastal parts of the area off Blaevandshuk and Skallingen, although the common scoter was found in relatively high numbers on the southeast slopes of Horns Rev and within the wind farm area in the April 2001 survey. Preference analyses of bird exploitation of the Horns Rev area showed that if the birds completely avoid the wind farm area after erection of the wind turbines, this will affects less than 1% of the different species, except divers of which 1.65% will be affected. If the birds avoid the wind farm area and an adjacent 4 km zone (worst case scenario), it is estimated to affect 11% of the common scoter, 10% of the gannet, 7-9% of the divers, alcids and velvet scoter and 0-6% of the remaining species. The seasonal occurrence of the recorded species was fully comparable to the seasonal occurrence of these species recorded at Blaevandshuk since 1963. Year-to-year variation in abundance between the seasons August 1999 - April 2000 and August 2000 - April 2001 was mainly found in species that migrate through the Horns Rev area (terns, gannet, kittiwake), and with less pronounced variation in

    This report presents the combined results of two years of base-line investigations of birds performed during August 1999 - April 2001 in relation to the proposed construction of an offshore wind farm at Horns Rev in the Danish part of the North Sea ca 14 km southwest of Blaevandshuk. Based on the distribution of the most abundant bird species recorded during 13 aerial surveys, there were no indications that the wind farm area was of any particular importance to the birds' exploitation of the Horns Rev area. Fish-eating species like divers, gannet, terns, auks and gulls generally showed scattered and variable distributions, occurring in the areas north and south of Horns Rev, and with low numbers occurring on the reef proper and within the planned wind farm area. The distribution of benthic foraging species, eider and common scoter, showed that they mainly exploited the coastal parts of the area off Blaevandshuk and Skallingen, although the common scoter was found in relatively high numbers on the southeast slopes of Horns Rev and within the wind farm area in the April 2001 survey.

    It was recently shown that duplications of the RevSex element, located 0.5 Mb upstream of SOX9, cause XX-disorder of sex development (DSD), and that deletions cause XY-DSD. To explore how a 148 kb RevSex duplication could have turned on gonadal SOX9 expression in the absence of SRY in an XX-male, we examined the chromatin landscape in primary skin fibroblast cultures from the index, his RevSex duplication-carrier father and six controls. The ENCODE project supports the notion that chromatin state maps show overlap between different cell types, i.e., that our study of fibroblasts could be of biological relevance. We examined the SOX9 regulatory region by high-resolution ChIP-on-chip experiments (a kind of "chromatin-CGH") and DNA methylation investigations. The RevSex duplication was associated with chromatin changes predicting better accessibility of the SRY-responsive TESCO enhancer region 14-15 kb upstream of SOX9. Four kb downstream of the TESCO evolutionary conserved region, a peak of the enhancer/promoter-associated H3K4me3 mark was found together with a major dip of the repressive H3K9me3 chromatin mark. Similar differences were also found when three control males were compared with three control females. A marked male/female difference was a more open chromatin signature in males starting ~400 kb upstream of SOX9 and increasing toward the SOX9 promoter. In the RevSex duplication-carrier father, two positions of DNA hypomethylation were also found, one corresponding to the H3K4me3 peak mentioned above. Our results suggest that the RevSex duplication could operate by inducing long-range epigenetic changes. Furthermore, the differences in chromatin state maps between males and females suggest that the Y chromosome or X chromosome dosage may affect chromatin conformation, i.e., that sex-dependent gene regulation may take place by chromatin modification.

    Projected energy requirements for the future suggest that we must employ atomic energy to generate electric power or face depletion of our fossil-fuel resources—coal, oil, and gas. In short, both conservation and economic considerations will require us to use nuclear energy to generate the electricity that supports our civilization. Until we reach the time when nuclear power plants are as common as fossil-fueled or hydroelectric plants, many people will wonder how the nuclear plants work, how much they cost, where they are located, and what kinds of reactors they use. The purpose of this booklet is to answer these questions. In doing so, it will consider only central station plants, which are those that provide electric power for established utility systems.

    Our whole industrial civilization depends upon cheap energy streaking out in all directions and under fingertip controls—and that would be very difficult without electric current. It would take enormous ingenuity to find substitutes. If all electricity were shut off, then all electronic devices would be dead. Electric lights would darken. Aluminum would become a rare metal. All factories would have to develop power sources on the spot and would have to switch to primitive, mechanical controls. Every house and every farm would have to give up items we have come to take for granted—not only electric lights, but electric irons, electric toasters, electric water pumps, electric control of furnaces, and so on.

    The purpose of this medical specialty book, besides presenting the state of the art in clinical radiotherapy and radiooncology, is to explain the basic principles of medical physics and radiobiology. Following a number of chapters on general topics and theory it provides detailed coverage of the individual organ systems, briefly addressing future aspects in the process. The authors relate their view that radiooncology as a medical specialty will continue to be under pressure to change and that it will take continuous innovation to secure its status within the interdisciplinary context around the treatment of cancer patients. The authors of this, the textbook's second edition, have dedicated much space to modern methods and techniques in order to do justice to these developments.

    A baseline description of the benthos was carried out in spring and autumn 2001 prior to the construction of an offshore wind farm at Horns Rev, situated approximately 15 km off Blaevands Huk, which is Denmark's most westerly point. The surveys have been conducted as part of an environmental monitoring programme for the introduction of hard bottom substrates in the North Sea. The establishment of a monitoring programme is required according to some environmental guidelines set up by the Danish Energy Agency for offshore wind farms. Because no environmental criteria existed for benthic communities in connection with the construction activities, no power analysis was made prior to the design of the monitoring programme. The monitoring programme established for the benthic infauna is thus somewhat limited and only major changes in the community structure are expected to be detectable. The baseline description for the benthic infauna can also be used for comparison of the stomach contents of fish in a comparative programme. A newly defined reference area may be introduced for the fish programme why sampling in this area was carried out in the autumn 2001. Samples were recovered at a total of 18 stations at 6 wind turbine locations in the wind farm area in June 2001 and at a total of 9 stations at 3 wind turbine locations in September 2001. In September additional sampling was carried out at 5 stations in a designated reference area. At the wind turbine locations sampling was carried out at 3 stations located 5, 25 and 100 m from the edge of the planned scour protection. Samples were analysed for sediment characteristics and for benthic infauna. Only the benthos relating to the macrofauna was investigated during the surveys. (au)

    The omission of the name 'Mycobacterium paraffinicum' from the Approved Lists of Bacterial Names was due to phenotypic confusion surrounding a close relationship with Mycobacterium scrofulaceum. Correspondingly, 'M. paraffinicum' strains grew slowly in > 7 days, stained acid-alcohol-fast and produced yellow-pigmented, smooth, waxy colonies in the dark at an optimal temperature of 35°C. However, 'M. paraffinicum' strains demonstrated no activity for urease, nicotinamidase or pyrazinamidase and lacked growth at 42°C, unlike M. scrofulaceum. The mycolic acid pattern, as determined by HPLC, clustered 'M. paraffinicum' with M. scrofulaceum, Mycobacterium avium and Mycobacterium parascrofulaceum. Strains were fully susceptible to linezolid, rifabutin, clarithromycin and amikacin. Examination of the historical reference strain of 'M. paraffinicum', ATCC 12670, and five additional isolates using comparative studies with 16S rRNA, hsp65 and rpoB gene and concatenated sequences showed that they formed a tight taxonomic group that was distinct from similar non-tuberculous mycobacteria. Multilocus enzyme electrophoresis (MEE) analysis confirmed a close association of the five additional isolates with the reference strain of 'M. paraffinicum' with a genetic distance of 0.12 and showed that all six strains were distinct from other closely related species. These genetic results provided unambiguous evidence of the uniqueness of this slowly growing, scotochromogenic species and supported the revival of the name as Mycobacterium paraffinicum (ex Davis, Chase and Raymond 1956) sp. nov., nom. rev. We propose the previously deposited reference strain ATCC 12670(T) =DSM 44181(T) =NCIMB 10420(T), located in collections worldwide, as the type strain.

    Full Text Available Three groups of Shami goats were randomly vaccinated with Brucevac (Rev. 1 vaccine. Group 1 was vaccinated subcutaneously with a full dose (1.54 x 109 organisms. Group 2 was vaccinated conjunctively with one eye drop (5.2 x 108 organisms, while Group 3 was injected subcutaneously with a reduced dose (7.1 x 105 organisms of vaccine. Blood samples were collected before vaccination, two, four, eight, 15 and 24 weeks post vaccination. All samples were tested through CFT, ELISA, SAT and Rose Bengal plate test. All serological tests used detected a higher percentage of vaccinated female kids with a full dose than they did in other groups vaccinated with a reduced dose or with a conjunctival dose of Rev.1 vaccine. The overall results suggested that 100% of animals vaccinated with a conjunctival dose became positive to CFT at two, four, eight and 15 weeks post vaccination, and then the percentage of seropositive animals declined and became 20% at 24 weeks post inoculation. The conjunctival route of vaccination significantly reduced the intensity and duration of the post vaccination serological response, which makes the use of this vaccine compatible with brucellosis programmes, even when these are based on a test-and–slaughter policy. The overall results showed that Shami goats responded to Rev.1 vaccine in the expected way. The majority of animals were seropositive to the CFT by two weeks after vaccination with higher numbers of seropositive animals in the kids group vaccinated with a full dose of Rev.1 vaccine.

    This annual report, which is a baseline and/or an evaluation of the effects of construction phase, is based on extracts from our consultants' annual reports. These annual reports are individual reports, in which surveys have been made during the year 2002 and reported in the beginning of 2003. Detailed information on methods, programmes and conclusions can be found in these reports. In general it should be noted that apparently the construction phase has not had any unintended effects on the parameters surveyed. Therefore we can also conclude that the protective measures established by Elsam, especially scaring devices/ramp-ups for marine mammals, have had the intended effect. Especially interesting parameters that should be mentioned are: Birds: The seagull species 'Herring Gulls' was found to be attracted by the wind farm during the construction period. The number of Divers has decreased, however statistically this decrease is very small as very few Divers have been observed under the baseline. Porpoises: Porpoises generally stayed away from the construction area during pile driving. This effect was intended and scaring devices were deployed in order to ensure that the animals' hearing was not permanently damaged. Seals: The purpose of the programme has not been to show statistically significant effects during the construction phase. The purpose was to get an idea of their behaviour during the construction phase within the wind farm as well as on the reef. It has been concluded that Horns Rev is not used as a foraging area as much as expected. It is used as transit area for bigger foraging sites in the North Sea. Sand eels and Spisula: A baseline survey of sand eels within the wind farm area has been made. It is shown that sand eels are found in the wind farm area. Spisula have been found in the wind farm area but not in the amount expected. Hard substrate habitat: Baseline surveys on fish have been made during the spring of 2002. The

The number of Divers has decreased, however statistically this decrease is very small as very few Divers have been observed under the baseline. Porpoises: Porpoises generally stayed away from the construction area during pile driving. This effect was intended and scaring devices were deployed in order to ensure that the animals' hearing was not permanently damaged. Seals: The purpose of the programme has not been to show statistically significant effects during the construction phase. The purpose was to get an idea of their behaviour during the construction phase within the wind farm as well as on the reef. It has been concluded that Horns Rev is not used as a foraging area as much as expected. It is used as transit area for bigger foraging sites in the North Sea. Sand eels and Spisula: A baseline survey of sand eels within the wind farm area has been made. It is shown that sand eels are found in the wind farm area. Spisula have been found in the wind farm area but not in the amount expected. Hard substrate habitat: Baseline surveys on fish have been made during the spring of 2002. The programme regarding the

    Surfaces exposed to a plasma experience a certain pressure that pushes them away from the volume. This effect has been investigated experimentally in a recent article by Thomas Trottenberg, Thomas Richter, and Holger Kersten from Kiel University/Germany [Eur. Phys. J. D 69, 91 (2015)]. The experimental results are impressive and have actually drawn the attention of the community to an interesting question which so far has been largely ignored. In addition to their experimental results the Kiel group proposes also a rough concept in order to explain their findings which provides certainly a basic qualitative understanding of the physical processes involved. However, on a closer inspection the picture developed so far is not entirely satisfying and the problem seems to require a more fundamental approach. This comment shows that the effect of the wall pressure can be described exactly using only analytical methods. The physical situation is analyzed by three different approaches. First, the simple case of only one spatial dimension is presented in detail. Second, the case of spherical symmetry is analyzed by some simplifying assumptions in order to investigate the effect of higher dimensionality. Third, a formal derivation for arbitrary geometry is given. This general result includes the one-dimensional case but does not allow a convenient connection between the pressures at the wall and in the center. Finally, the results are summarized and some conclusions are drawn.

  14. Analysis of mutagenic DNA repair in a thermoconditional mutant of Saccharomyces cerevisiae. IV. Influence of DNA replication and excision repair on REV2 dependent UV-mutagenesis and repair

    A double mutant being thermoconditionally defective in mutation induction as well as in repair of pre-lethal UV-induced DNA damage (rev2ts) and deficient in excision repair (rad3-2) was studied in temperature-shift experiments. The influence of inhibitors of DNA replication (hydroxyurea, aphidicolin) was determined. Additionally, an analysis of the dose-response pattern of mutation induction (mutation kinetics) at several ochre alleles was carried out. It was concluded that the UV-inducible REV2 dependent mutagenic repair process is not induced in excision-deficient cells. In excision-deficient cells, REV2 dependent mutation fixation is slow and mostly post-replicative though not dependent on DNA replication. The REV2 mediated mutagenic process could be separated from the repair function.

  17. The role of hRev7, the accessory subunit of hPolζ, in translesion synthesis past DNA damage induced by benzo[a]pyrene diol epoxide (BPDE

    Full Text Available Abstract Background DNA polymerase zeta (Polζ is a specialized DNA polymerase that, unlike classical replicative polymerases, is capable of replicating past DNA lesions, i.e. of performing translesion synthesis (TLS. The catalytic subunit of hPolζ, hRev3, has been shown to play a critical role in DNA damage-induced mutagenesis in human cells, but less is known about the role of hRev7, the accessory subunit of hPolζ, in such mutagenesis. To address this question, we recently generated human fibroblasts with very significantly reduced levels of hRev7 protein and demonstrated that hRev7 is required to protect cells from ultraviolet(254 nm (UV radiation-induced cytotoxicity and mutagenesis (McNally et al., DNA Repair 7 (2008 597-604. The goal of the present study was to determine whether hRev7 is similarly involved in the tolerance of DNA damage induced by benzo[a]pyrene diol epoxide (BPDE, the reactive form of the widespread environmental carcinogen benzo[a]pyrene. Methods To determine whether hRev7 also plays a role in protecting human cells from the cytotoxicity and mutagenesis induced by benzo[a]pyrene diol epoxide (BPDE, cell strains with reduced hRev7 were compared to their parental strain and a vector control strain for the effect of BPDE on cell survival, induction of mutations, and the ability to progress through the cell cycle. Results The results show that cell strains with reduced hRev7 are more sensitive to the cytotoxic effect of BPDE than the control strains, and progress through S-phase at a slower rate than the control cells following BPDE treatment, indicating that hRev7, and likely hPolζ, is required for efficient bypass of BPDE-induced DNA lesions. However, neither the frequency nor kinds of mutations induced by BPDE in cells with reduced hRev7 differ significantly from those induced in the control strains, suggesting that hPolζ is not essential for inserting nucleotides opposite BPDE-induced DNA damage.

    Two HIV-1 accessory proteins, Vpu and Vif, are notoriously difficult to express autonomously in the absence of the viral Tat and Rev proteins. We examined whether the codon bias observed in the vpu and vif genes relative to highly expressed human genes contributes to the Rev dependence and low expression level outside the context of the viral genome. The entire vpu gene as well as the 5' half of the vif gene were codon optimized and the resulting open reading frames (ORFs) (vphu and hvif, respectively) were cloned in autonomous expression vectors under the transcriptional control of the CMV promoter. Codon optimization efficiently removed the expression block observed in the native genes and allowed high levels of Rev- and Tat-independent expression of Vpu and Vif. Most of the higher protein levels detected are accounted for by enhanced steady-state levels of the mRNA encoding the optimized species. Nuclear run-on experiments show for the first time that codon optimization has no effect on the rate of transcriptional initiation or elongation of the vphu mRNA. Instead, optimization of the vpu gene was found to stabilize the vphu mRNA in the nucleus and enhance its export to the cytoplasm. This was achieved by allowing the optimized mRNA to use a new CRM1-independent nuclear export pathway. This work provides a better understanding of the molecular mechanisms underlying the process of codon optimization and introduces novel tools to study the biological functions of the Vpu and Vif proteins independently of other viral proteins

  19. Characterization of an internal ribosomal entry segment within the 5' leader of avian reticuloendotheliosis virus type A RNA and development of novel MLV-REV-based retroviral vectors.

    The murine leukemia virus (MLV)-related type C viruses constitute a major class of retroviruses that includes numerous endogenous and exogenous mammalian viruses and the related avian spleen necrosis virus (SNV). The MLV-related viruses possess a long and multifunctional 5' untranslated leader involved in key steps of the viral life cycle--splicing, translation, RNA dimerization, encapsidation, and reverse transcription. Recent studies have shown that the 5' leader of Friend murine leukemia virus and Moloney murine leukemia virus can direct cap independent translation of gag precursor proteins (Berlioz et al., 1995; Vagner et al., 1995b). These data, together with structural homology studies (Koning et al., 1992), prompted us to undertake a search for new internal ribosome entry segment (IRES) of retroviral origin. Here we describe an IRES element within the 5' leader of avian reticuloendotheliosis virus type A (REV-A) genomic RNA. Data show that the REV-A 5' IRES element maps downstream of the packaging/dimerization (E/DLS) sequence (Watanabe and Temin, 1982; Darlix et al., 1992) and the minimal IRES sequence appears to be within a 129 nt fragment (nucleotides 452-580) of the 5' leader, immediately upstream of the gag AUG codon. The REV-A IRES has been successfully utilized in the construction of novel high titer MLV-based retroviral vectors, containing one or more IRES elements of retroviral origin. These retroviral constructs, which represent a starting point for the design of novel vectors suitable for gene therapy, are also of interest as a model system of internal translation initiation and its possible regulation during development, cancer, or virus infection.

    The present report presents the base-line investigations of birds conducted during August 1999-April 2001 in relation to construction of an offshore wind farm at Horns Rev, 14 km west-south-west of Blaevandshuk, in the Danish North Sea. The report also presents data collected during the period September 2001-April 2002, when construction of the wind farm was in progress. The wind farm will consist of 80 wind turbines, each of 2 MW, and cover an area of c. 20 km 2 . The eastern part of the North Sea constitutes major staging and wintering grounds for huge numbers of water- and seabirds. The area is also known to be an important site for migrating birds, which especially in autumn pass in large numbers. As Denmark has obligations to protect and maintain the bird populations it was laid down in the approval for erection of the wind farm that the impact on birds should be investigated. According to the 1% criteria defined in the Ramsar Convention, the eastern part of the North Sea including the wind farm area is of international importance to divers, Common Tern, and Sandwich Tern. A number of other species, e.g. Common Eider, Common Scoter, Guillemot and Razorbill, are present in the area in significant numbers as well, though these numbers do not make up 1% of the populations. Detailed distributions of birds in the area around and at Horns Rev were virtually unknown until initiation of this project. Previous bird counts in this area have been carried out almost exclusively from the coast and detailed knowledge exists concerning the numbers of roosting at and migrating birds from the westernmost point of Jutland, Blaevandshuk. To describe the numbers and distributions of birds staging and wintering in the Horns Rev area, bird investigations were initiated in 1999 by using standardised transect counts from aircraft. Up to April 2002, 18 aerial counts have been carried out over an area of c. 1,700 km 2 centred on the Horns Rev project area. (au)

    Full Text Available Coke deposition is a major problem for several refinery and petrochemical processes, among which steam cracking for ethylene production. Decreasing coking rates will reduce decoking frequency and will also decrease heat transfer degradation. For these processes, a means of reducing coking phenomena is the application of anticoking coatings on the reactor walls. For this purpose a methodology was developed under a CEC Brite-Euram project with steam cracking as the main application. A first selection of the coatings and their techniques of deposition was performed according to their composition (non catalytic compounds, their resistance to carburization and oxidation and also according to the nature of the substrate. The feasibility of coating deposition was studied for small diameter furnace tubes and the techniques were perfected in particular with respect to the physicochemical characterization of the coatings and their resistance during thermal cycling and coking-decoking cycles. For the thermal cycling and the coking evaluation, industrial conditions were reproduced as closely as possible. For coking tests, a microreactor with complete mixing of the gas phase was developed for temperatures up to 950°C. The coking behavior of the coated samples was compared with conventional refractory alloys: reduction of the coking rate by a factor of 3 was measured with the most promising coating. This work was completed by the kinetic modelling of coking on uncoated materials. La formation de coke est un problème crucial pour de nombreux procédés pétrochimiques. Ralentir le cokage permet de réduire la fréquence des décokages et de limiter la dégradation du transfert thermique. Un des moyens envisageables pour réduire le cokage est le dépôt d'un revêtement à la paroi de ces réacteurs. La mise au point de tels revêtements a fait l'objet d'un projet de recherche européen Brite-Euram, pour lequel le vapocraquage a été la principale

    Experimental observations have put in evidence autonomous self-sustained circadian oscillators in most mammalian cells, and proved the existence of molecular links between the circadian clock and the cell cycle. Some mathematical models have also been built to assess conditions of control of the cell cycle by the circadian clock. However, recent studies in individual NIH3T3 fibroblasts have shown an unexpected acceleration of the circadian clock together with the cell cycle when the culture medium is enriched with growth factors, and the absence of such acceleration in confluent cells. In order to explain these observations, we study a possible entrainment of the circadian clock by the cell cycle through a regulation of clock genes around the mitosis phase. We develop a computational model and a formal specification of the observed behavior to investigate the conditions of entrainment in period and phase. We show that either the selective activation of RevErb-α or the selective inhibition of Bmal1 transcription during the mitosis phase, allow us to fit the experimental data on both period and phase, while a uniform inhibition of transcription during mitosis seems incompatible with the phase data. We conclude on the arguments favoring the RevErb-α up-regulation hypothesis and on some further predictions of the model. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Persistent aryl hydrocarbon receptor (AhR) agonists elicit dose-dependent hepatic lipid accumulation, oxidative stress, inflammation, and fibrosis in mice. Iron (Fe) promotes AhR-mediated oxidative stress by catalyzing reactive oxygen species (ROS) production. To further characterize the role of Fe in AhR-mediated hepatotoxicity, male C57BL/6 mice were orally gavaged with sesame oil vehicle or 0.01–30 μg/kg 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) every 4 days for 28 days. Duodenal epithelial and hepatic RNA-Seq data were integrated with hepatic AhR ChIP-Seq, capillary electrophoresis protein measurements, and clinical chemistry analyses. TCDD dose-dependently repressed hepatic expression of hepcidin (Hamp and Hamp2), the master regulator of systemic Fe homeostasis, resulting in a 2.6-fold increase in serum Fe with accumulating Fe spilling into urine. Total hepatic Fe levels were negligibly increased while transferrin saturation remained unchanged. Furthermore, TCDD elicited dose-dependent gene expression changes in heme biosynthesis including the induction of aminolevulinic acid synthase 1 (Alas1) and repression of uroporphyrinogen decarboxylase (Urod), leading to a 50% increase in hepatic hemin and a 13.2-fold increase in total urinary porphyrins. Consistent with this heme accumulation, differential gene expression suggests that heme activated BACH1 and REV-ERBα/β, causing induction of heme oxygenase 1 (Hmox1) and repression of fatty acid biosynthesis, respectively. Collectively, these results suggest that Hamp repression, Fe accumulation, and increased heme levels converge to promote oxidative stress and the progression of TCDD-elicited hepatotoxicity. - Highlights: • TCDD represses hepatic hepcidin expression, leading to systemic iron overloading. • Dysregulation of heme biosynthesis is consistent with heme and porphyrin accumulation. • Heme-activated REV-ERBα/β repress circadian-regulated hepatic lipid metabolism. • Disruption of iron

    Brucellosis is known as one of important zoonosis. Studying the histological and biochemical effects of the disease could help to increase our knowledge about it. The aim of the present study was to evaluate changes of plasma parameters after intraperitoneal injection of two species of Brucella (Brucella melitensis and Brucella abortus) and two vaccines (Rev-1, RB-51) in the rat. Forty male rats were divided into five groups (n = 8 in each group). Two groups received suspensions of Brucella abortus and Brucella melitensis and two other groups were injected intraperitoneally with two mentioned vaccines and the last group received only distilled water. The results showed a significant increase in sphingosine 1-phosphate, Malondialdehyde, hepcidin, homocysteine, cardiac troponin I and copper levels and a considerable decrease in the levels of iron and zinc (P ≤ 0.01) in infected groups compared to the control animals. In vaccinated groups, hepcidin was increased but other parameters were not changed in comparison to the control group. It can be concluded that increase of homocysteine and cardiac troponin I in brucellosis could be a warning for cardiac adverse effects. Besides, increase of sphingosine 1-phosphate probably indicates its stimulant and modulatory effects in anti- Brucellosis biochemical pathways of the host. Copyright © 2017 Elsevier Ltd.

    U. S. NRC Regulation Guide 1.52 regulating ESF ACS in nuclear power plants has been revised to revision 3. To apply reduction of operability test time, allowance of alternative challenge agents for in-place leak test of HEPA filters, and upgrade of Methyl Iodide penetration acceptance criterion in activated carbon performance test suggested in Reg. Guide 1.52(Rev.3) on Yonggwang units 5 and 6 ESF ACSes, technical feasibility study was carried out with on-site experiments as well as experiments with a lab-scale model. It was confirmed that the moisture in the system returned to the level before the test in 1 or 4 days even though the moisture was removed during the operability test lasting more than 10 hours. Therefore, it is appropriate to perform monthly operability test in 15 minutes just long enough to check the operability of equipment. To change challenge material for in-place HEPA filter leak test, size of aerosol, production rate, and leak detection capability were compared for DOP and PAO. It was concluded that PAO can be substituted for DOP in nuclear power plants. The upgrade of Methyl Iodide penetration acceptance criterion from 0.175 % to 0.5 % in active carbon filter bed deeper than 4 inches was to conform to the change of activated carbon performance test method to ASTM D3803(1989). It was confirmed that Methyl Iodide penetration acceptance criterion of 0.5 % under 30 .deg. C

    Full Text Available Abstract Background Alternative processing of α-thyroid hormone receptor (TRα, NR1A1 mRNAs gives rise to two functionally antagonistic nuclear receptors: TRα1, the α-type receptor, and TRα2, a non-hormone binding variant that is found only in mammals. TRα2 shares an unusual antisense coding overlap with mRNA for Rev-erbα (NR1D1, another nuclear receptor protein. In this study we examine the structure and expression of these genes in the gray short-tailed opossum, Monodelphis domestica, in comparison with that of eutherian mammals and three other marsupial species, Didelphis virginiana, Potorous tridactylus and Macropus eugenii, in order to understand the evolution and regulatory role of this antisense overlap. Results The sequence, expression and genomic organization of mRNAs encoding TRα1 and Rev-erbα are very similar in the opossum and eutherian mammals. However, the sequence corresponding to the TRα2 coding region appears truncated by almost 100 amino acids. While expression of TRα1 and Rev-erbα was readily detected in all tissues of M. domestica ages 0 days to 18 weeks, TRα2 mRNA was not detected in any tissue or stage examined. These results contrast with the widespread and abundant expression of TRα2 in rodents and other eutherian mammals. To examine requirements for alternative splicing of TRα mRNAs, a series of chimeric minigenes was constructed. Results show that the opossum TRα2-specific 5' splice site sequence is fully competent for splicing but the sequence homologous to the TRα2 3' splice site is not, even though the marsupial sequences are remarkably similar to core splice site elements in rat. Conclusions Our results strongly suggest that the variant nuclear receptor isoform, TRα2, is not expressed in marsupials and that the antisense overlap between TRα and Rev-erbα thus is unique to eutherian mammals. Further investigation of the TRα and Rev-erbα genes in marsupial and eutherian species promises to yield

    The book deals with the emotional aspects of the controversy on peaceful use of nucleon energy. It would be self-delusion to expect a near end of the nuclear discussion. Advocates and opponents confront each other almost beyond reconcilation, handly prepared to hear the opposite side's arguments. What is the reason. As C.F. von Weizsaecker remarked to the author: 'To understand a phenomenon like the present nuclear energy debate is hardly possible without recurring to psychology'. In this paperback an entirely new approach to the nuclear energy debate is opened. The book has found wide attention. As the 'Neue Zuercher Zeitung' wrote: 'The author's psychology analysis of the nuclear energy controversy and especially its interpretation based on Jung's depth psychology combine to form a terse survey of many phenomena not so far systematically studied'.

    The author, one of the most consistent opponents of nuclear power, strikes a balance after the Chernobyl catastrophe. He relentlessly analyses the 'German nuclear situation', developments to be expected from risks and catastrophic events. He exposes statements offered by the owners of power plants and by politicians as attempts to play risks down, and hopes to achieve a turnabout yet. The conjunction of technical and physical arguments with a fundamental criticism of the ideology of economic growth is what distinguishes this book from other publications critical of nuclear energy. But the author does not content himself with criticism, he goes on to point out realistic measures for opting out of nuclear energy. (orig./HSCH) With 10 figs. and maps [de

    International Nuclear Information System (INIS)

    2011-01-01

    The International Atomic Energy Agency has been active in the promotion of non-destructive testing (NDT) technology in the world for many decades. The prime reason for this interest has been the need for stringent standards for quality control for safe operation of nuclear as well as other industrial installations. It has successfully executed a number of programmes including technical co-operation (TC) projects (national and regional) and the coordinated research projects (CRP) of which NDT was an important part. Through these programmes a large number of persons in the Member States have been trained, leading to establishment of national certifying bodies (NCB) responsible for training and certification of NDT personnel. Consequently, a state of self-sufficiency in this area of technology has been achieved in many of them. All along there has been a realization of the need to have well established training guidelines and related books in order, firstly, to guide the IAEA experts who were involved in this training programme and, secondly, to achieve some level of international uniformity and harmonization of training materials and consequent competence of NDT personnel. The syllabi for training courses have been published in the form of IAEA-TECDOC publications. The first was IAEA-TECDOC-407 (1987), which contained syllabi for the basic five methods, i.e. liquid penetrant testing, magnetic particle testing, eddy current testing, radiographic testing and ultrasonic testing. To accommodate advancements in NDT technology, later versions of this publication were issued in 1991, 2002 and 2008, the current version being IAEA-TECDOC-628/Rev.2 (2008), which includes additional and more advanced NDT methods. This IAEA-TECDOC, as well as most of the international standards on the subject of training and certification of NDT personnel including ISO 9712 (2005), define three levels of competence. Among these, level 1 is the lowest and level 3 the highest. The intermediate

    2006-12-15

    The concept of a Multi-cavity Cold Gas PressuriZeR(MCGPZR) is applied to the SMART: The pressurizer system includes in-vessel cavities and out-of-vessel gas cylinders holding the gas supply/vent system. The gas cylinders are connected to the one of the in-vessel cavities via piping with valves. A pressurizer is maintained at a cold temperature of less than about 120 .deg. C which is realized with coolers installed in and with wet thermal insulators installed on one of the cavities located inside the hot reactor vessel, to minimize the contribution of a steam partial pressure and is filled with nitrogen gas as a pressure-absorbing medium. The working medium and working temperature of the MCGPZR is totally different from that of a hot steam pressurizer of the commercial PWR. In addition, the MCGPZR is intended to be designed to meet a pressure transient during normal power operation (by its gas volume capacity) without using an active control system and during plant heatup/cooldown operation by using an active gas control (filling/venting) system. Therefore in order to evaluate the feasibility of the concept of the MCGPZR and its intended design goal, the thermal hydraulic behaviors and controllability of the MCGPZR during transients especially a heatup/cooldown operation must be analyzed. In this study, a thermal hydraulic transient analysis computer code, PZRTR rev 1, for the Reactor Coolant System(RCS) of an integral reactor composed of the MCGPZR, modular Once-Through Steam Generators(OTSGs), a core and a reactor coolant loop is developed. The pressurizer module (MCGPZR module) of the PZRTR rev 1 code is based on a two-fluid, nonhomogeneous, nonequilibrium model for the two-phase system behavior and the OTSG module is based on a homogeneous equilibrium model of the two-phase flow process. The core module is simply based on the axial power distributions and the reactor coolant loop is based on the temperature distributions. The code is currently dedicated for the

    2017-11-01

    We show that the simplicity constraints, which define the dynamics of spin foam models, imply, and are implied by, the first law of thermodynamics, when the latter is applied to causal diamonds in the quantum spacetime. This result reveals an intimate connection between the holographic nature of gravity, as reflected by the Bekenstein entropy, and the fact that general relativity and other gravitational theories can be understood as constrained topological field theories. To state and derive this correspondence we describe causal diamonds in the causal structure of spin foam histories and generalize arguments given for the near horizon region of black holes by Frodden, Gosh and Perez [Phys. Rev. D 87, 121503 (2013); , 10.1103/PhysRevD.87.121503Phys. Rev. D 89, 084069 (2014); , 10.1103/PhysRevD.89.084069Phys. Rev. Lett. 107, 241301 (2011); , 10.1103/PhysRevLett.107.241301Phys. Rev. Lett.108, 169901(E) (2012)., 10.1103/PhysRevLett.108.169901] and Bianchi [arXiv:1204.5122.]. This allows us to apply a recent argument of Jacobson [Phys. Rev. Lett. 116, 201101 (2016).10.1103/PhysRevLett.116.201101] to show that if a spin foam history has a semiclassical limit described in terms of a smooth metric geometry, that geometry satisfies the Einstein equations. These results suggest also a proposal for a quantum equivalence principle.

    Between 20 and 24 June 2005 the Centre Européen de Calcul Atomique et Moléculaire - or CECAM, as it is more widely known - hosted a workshop entitled State-of-the-art, developments and perspectives of real-space electronic structure methods in condensed-matter and chemical physics, organized with the support of CECAM itself and the ?k network. The workshop was attended by some forty participants coming from fifteen countries, and about thirty presentations were given. The workshop provided a lively forum for the discussion of recent methodological developments in electronic structure calculations, ranging from linear-scaling methods, mesh techniques, time-dependent density functional methods, and a long etcetera, which had been our ultimate objective when undertaking its organization.The first-principles simulation of solids, liquids and complex matter in general has jumped in the last few years from the relatively confined niches in condensed matter and materials physics and in quantum chemistry, to cover most of the sciences, including nano, bio, geo, environmental sciences and engineering. This effect has been propitiated by the ability of simulation techniques to deal with an ever larger degree of complexity. Although this is partially to be attributed to the steady increase in computer power, the main factor behind this change has been the coming of age of the main theoretical framework for most of the simulations performed today, together with an extremely active development of the basic algorithms for its computer implementation. It is this latter aspect that is the topic of this special issue of physica status solidi.There is a relentless effort in the scientific community seeking to achieve not only higher accuracy, but also more efficient, cost-effective and if possible simpler computational methods in electronic structure calculations [1]. From the early 1990s onwards there has been a keen interest in the computational condensed matter and chemical physics communities in methods that had the potential to overcome the unfavourable scaling of the computational cost with the system size, implicit in the momentum-space formalism familiar to solid-state physicists and the quantum chemistry approaches more common in chemical physics and physical chemistry. This interest was sparkled by the famous paper in which Weitao Yang [2] introduced the Divide and Conquer method. Soon afterwards several practical schemes aiming to achieve linear-scaling calculations, by exploiting what Walter Kohn called most aptly the near-sightedness of quantum mechanics [3], were proposed and explored (for a review on linear-scaling methods, see [4]). This search for novel, more efficient and better scaling algorithms proved to be fruitful in more than one way. Not only was it the start of several packages which are well-known today (such as Siesta, Conquest, etc.), but it also leads to new ways of representing electronic states and orbitals, such as grids [5, 6], wavelets [7], finite elements, etc. Also, the drive to exploit near-sightedness attracted computational solid state physicists to the type of atomic-like basis functions traditionally used in the quantum chemistry community. At the same time computational chemists learnt about plane waves and density functional theory, and thus a fruitful dialogue was started between two communities that hitherto had not had much contact.Another interesting development that has begun to take place over the last decade or so is the convergence of several branches of science, notably physics, chemistry and biology, at the nanoscale. Experimentalists in all these different fields are now performing highly sophisticated measurements on systems of nanometer size, the kind of systems that us theoreticians can address with our computational methods, and this convergence of experiment and theory at this scale has also been very fruitful, particularly in the fields of electronic transport and STM image simulation. It is now quite common to find papers at the cutting edge of nanoscience and nanotechnology co-authored by experimentalists and theorists, and it can only be expected that this fruitful interplay between theory and experiment will increase in the future.It was considerations such as these that moved us to propose to CECAM and ?k the celebration of a workshop devoted to the discussion of recent developments in electronic structure techniques, a proposal that was enthusiastically received, not just by CECAM and ?k, but also by our invited speakers and participants. Interest in novel electronic structure methods is now as high as ever, and we are therefore very happy that physica status solidi has given us the opportunity to devote a special issue to the topics covered in the workshop. This special issue of physica status solidi gathers invited contributions from several attendants to the workshop, contributions that are representative of the range of topics and issues discussed then, including progress in linear scaling methods, electronic transport, simulation of STM images, time-dependent DFT methods, etc. It rests for us to thank all the contributors to this special issue for their efforts, CECAM and ?k for funding the workshop, physica status solidi for agreeing to devote this special issue to the workshop, and last but not least Emmanuelle and Emilie, the CECAM secretaries, for their invaluable practical help in putting this workshop together

    This document gathers notes taken during a course of nuclear physics given by Daniel Decamp in 2013. It addresses the nucleus general characteristics (nucleons), the issues of nucleus mass and of bound energy, the liquid drop model, and applications. The next part addresses the dimension of nuclei and nuclear density: Rutherford scattering (scattering of a charged particle by a nucleus, particle deflection angle), notion of cross section (probability of scattering at a given angle, experimental verifications, generalisation of the notion of cross section), and charge distribution within the nucleus (density of final states, differential cross section of elastic scattering, experimental results, nuclear density). The next part addresses radioactivity: generalities, energetic conditions, mass parabola, law of radioactivity (fundamental law, half-life, line width, decay products, natural radioactivity and radioactive families). The next parts address applications of radioactivity: carbon-14 dating, dating of rocks and meteorites), artificial radioactivity (notion of cross section, production of radioactive nuclei), the theoretical approach to radioactivity (semi-conventional BKW approach, other calculation method, Gramow's theory of radioactivity, Fermi's theory of radioactivity), and nuclear models with models based on independent particles (Fermi model, layer model and its applications) and collective models (rotational and vibrational models)

    We have recently observed a growing interest in using the powerful technique of optical modulation spectroscopy. These applications are related mostly to the characterization of low dimensional semiconductor structures and devices based on them.The International Workshop on Modulation Spectroscopy of Semiconductor Structures (MS3) at the beginning of July 2004 gathered in Wrocaw (in the southwest part of Poland) almost 40 participants, half of them from abroad. The 8 invited and 16 contributed talks were presented by the leaders of research teams from the USA, Japan, Taiwan, Canada, Germany, France, the Netherlands, Sweden, Ireland, Russia, Lithuania and Poland. Part of the MS3 workshop was held at the Laboratory of Advanced Optical Spectroscopy, Institute of Physics, Wrocaw University of Technology, where discussions on technical matter of the modulation spectroscopy were carried out in a relaxing atmosphere over a cup of coffee.The topics of the MS3 workshop included: advantages of photoreflectance, electroreflectance, contactless electroreflectance, thermoreflectance, differential reflectance and wavelength-modulated surface photovoltage spectroscopy. The applications of the above methods to investigate transistor, diode and laser structures including VCSELs, low dimensional structures of both wings of the spectrum, i.e. wide band gap materials like GaN, AlGaN, ZnO and low band gap materials such as GaInN(Sb)As, InAs, InSb, and FeSi2 were demonstrated.It is our great pleasure to publish the most interesting of the MS3 workshop presentations in this issue of physica status solidi (a).The organizers acknowledge Wrocaw University of Technology, the Center of Exellence CEPHONA from the Institute of Electron Technology in Warsaw and the Polish Committee for Scientific Research for financial support of the workshop.

    The Third International Conference on Magnetic and Superconducting Materials (MSM03) belongs to a series of conferences, held biannually, aiming at providing a forum to the scientists in the magnetic and superconducting materials areas over the world.The first conference of the series (MSM99) was held in Iran with the proceedings published by World Scientific in 2000, and the second conference (MSM01) was held in Jordan with the proceedings published in Physica B 321 (2002).MSM03 was organized by the Materials Physics Laboratory, Sfax University (Laboratoire de Physique des Matériaux de la Faculté des Sciences de Sfax), with many domestic and international supporting institutions. It was held in Monastir (Tunisia), 1-4 September 2003, with over 150 participants and keynote lecturers attending from the following countries: Algeria, Austria, China, Czech Republic, Egypt, France, Germany, Hungary, Iran, Italy, Japan, Jordan, Morocco, Netherlands, Pakistan, Poland, Russia, Spain, Sudan, Sultanate of Oman, Taiwan, Tunisia, United Kingdom and United States of America.Altogether, about 170 papers on a variety of subjects relevant to the topic of the conference were presented, out of which 42 were keynote lectures. The submissions were peer-reviewed, and ultimately 115 articles were selected for publication in this journal. However, it must be noted that 13 of 39 keynote speakers did not submit their manuscripts for publication. Invited and other speakers were distinguished members of the international scientific community who are interested in pure sciences and materials research, and involved in the fabrication, characterization and investigation of the physical properties of magnetic and superconducting materials. High-caliber scientists attended the conference contributing to its success and the event resulted in new international relationships in research and cooperation. The Chairman of the Organizing Committee was Professor Abdelwaheb Cheikhrouhou, Materials Physics Laboratory, Sciences Faculty of Sfax (Tunisia) and the Co-Chairmen were Professor Sami Mahmood, Dean of Sciences at Yarmouk University (Jordan) and Professor Mohamed Akhavan from the Sharif University of Technology (Iran). The four-day conference consisted of several oral and poster sessions, followed by social programs in the evenings. The success of the event could be measured during the closing session on the last day, when several delegates emphasized the high-quality science that had been evident at the conference. A post conference three-day tour to the south of Tunisia (Matmata, Douz City: the gate of desert and the mountains oasis: Tamerza, Mides and Chebika) was also arranged. The conference was generously sponsored by: - The Tunisian Ministry of High Education, Scientific Research and Technology - The Tunisian Secretary of State for Scientific Research and Technology - The Tunisian National Office of Tourism - The Abdus Salam International Centre for Theoretical Physics (ICTP) - French Institute for Cooperation in Tunisia - Tunisian-Italian Scientific Partnership - British Gas - Tunisian Society for Electricity and Gas - Imex Olive Oil -Confiserie TRIKI Le Moulin The next MSM conference in 2005 will be held in Morocco.

    Physica status solidi was founded in 1961 by a number of eminent solid state physicists as an attempt to overcome the iron curtain, which then separated East and West, at least in the field of science. Since that time our world has changed quite a bit, and so have the boundary conditions of science publishing. However, one thing has not changed: then as now, the general policy and development of a respectable scientific journal should be determined by a board of independent scientists, who volunteer to assume responsibility for the scientific content of the journal, to assure a fair and critical peer review process for all submitted manuscripts, and, in cases of conflict, to finally decide which papers will be published and which will not.As a matter of fact, an international Board of Editors which consists of scientists coming from different countries and continents, with a good reputation in their respective community, and without any conflict of interest with the Publisher of the journal is, in my opinion, these days more important than ever. As our daily scientific work becomes increasingly specialized, but at the same time also increasingly interdisciplinary, we are more and more forced to trust the quality and reliability of published scientific results in the literature, without really having a chance to come to an independent opinion on our own. This is one of the reasons why the many recent cases of plagiarism, scientific misconduct, or outright fraud have caused such a high level of public awareness. It is quite clear that without a serious peer review there would be an even larger number of such cases in the literature, and that without the responsible action taken by concerned Journal Editors, many of the revealed cases probably would have remained under the carpet.It is, therefore, a particular pleasure for me to introduce to you on the following pages the current Editorial Board of physica status solidi (b) in the form of a brief curriculum vitae, a photograph, and an e-mail address (in case you want to contact our Editors directly!). Of course, since 1961 the Editorial Board of our journal has undergone many changes and will continue to do so, but we always have attempted to maintain a good balance between the different areas of solid state physics, between theory and experiment, and between different countries. And although nothing is perfect, I hope that you will find at least one or two board members, who are known to you through their contributions to the literature in solid state physics.For me, this is the perfect occasion to thank all Members of the Editorial Board, past and present, for their advice, continuing support, and dedication!

    This issue of physica status solidi (a) contains the majority of papers presented at the 2nd Sino-German Symposium The Silicon Age which was held at the Lindner Hotel Cottbus, Germany, 19-24 September 2005. This meeting followed the 1st Symposium Progress in Silicon Materials held in June 2002 in Hangzhou, P.R. China. 8 Chinese and 14 German scientists from universities, research institutes and industry were invited to present their views about different aspects of silicon.There was a continuous progress in silicon materials development during the last 40-50 years, driven by the need of the IC industry for better and larger monocrystalline silicon wafers. Moreover, low-cost crystalline silicon now dominates the world's production of solar cells in the photovoltaics industry. Furthermore, there are intensive research activities worldwide for on-chip integration of Si-based photonics in CMOS technology. In addition, new areas being connected with silicon are starting to appear, namely Si-based biochips and nanoelectronics. Silicon, one can reasonably argue, is already the most investigated of all materials. However, there is still a need for continuation of research and development regarding numerous aspects of Si and also SiGe, including related technologies, advanced diagnostics or the role of crystal defects, which are the working fields of many laboratories all over the world. This was also shown by the presentations at the symposium and can be found in the contributions contained in this issue.The organizers would like to thank the participants for their high level contributions and discussions during the symposium. This intensive and open communication allowed the participants to create synergies between the different fields of silicon research and also to build up relationships for cooperation between Chinese and German research groups.Finally, we would like to thank the Sino-German Science Center for the financial support of the symposium.

    Full Text Available The paper presents a study on translations of a Greek word ποταμοφόρητος occurring in Rev 12 : 15. The Greek hapax legomenon ποταμοφόρητος is used in Rev 12 : 15. The part of the sentence containing ποταμοφόρητος is translated as: to sweep her away with the current. G. Schneider suggests a correction of the meaning of the word, concentrating on the conjectural purpose of being taken by water (drowning. In order to analyse this issue we begin with the study of etymology of the ποταμοφόρητος. It comes from the noun ποταμός and the adjective φορητός, which is a derivative of φορέω. Composita (compounds formed with φορητός did not refer to any idea of a mortal threat. Till the turn of 19th century ποταμοφόρητος, apart from the Bible, was only certified in the Hesychius’ Lexicon (5th or 6th century. The Egyptian papyri, uncovered and analysed on the turn of the 19th and the 20th century, in which the ποταμοφόρητος is related to the overflows of the Nile, let us doubt Schneider’s proposal, however, still do not solve the problem. The next stage of the research consisted of the analysis of the classical and antique translations of Rev (VL, Vg, Syriac and Coptic translations, as well as Latin and Greek patristic commentaries, which support one of the aforementioned interpretations. The commentators understood the river carrying the Woman as the image of Church persecution and a desire to place the Church under the command of evil forces. One of the versions of the translation of Vetus Latina (type I suggests that the archetype of the water torrent in Rev was the Nile. In the light of classical explanations as to the reasons of the river’s floodings, as well as the parallel in Ezek 29 : 3. 6 we can assume that it was the Nile that served as the archetype of the spewing torrent for the author of the Revelation.

    Translesion synthesis (TLS) of the N2-2′-deoxyguanosine (dG-N2-IQ) adduct of the carcinogen 2-amino-3-methylimidazo[4,5-f]quinoline (IQ) was investigated in human embryonic kidney 293T cells by replicating plasmid constructs in which the adduct was individually placed at each guanine (G1, G2, or G3) of the NarI sequence (5′-CG1G2CG3CC-3′). TLS efficiency was 38%, 29%, and 25% for the dG-N2-IQ located at G1, G2, and G3, respectively, which suggests that dG-N2-IQ is bypassed more efficiently by one or more DNA polymerases at G1 than at either G2 or G3. TLS efficiency was decreased 8–35% in cells with knockdown of pol η, pol κ, pol ι, pol ζ, or Rev1. Up to 75% reduction in TLS occurred when pol η, pol ζ, and Rev1 were simultaneously knocked down, suggesting that these three polymerases play important roles in dG-N2-IQ bypass. Mutation frequencies (MFs) of dG-N2-IQ at G1, G2, and G3 were 23%, 17%, and 11%, respectively, exhibiting a completely reverse trend of the previously reported MF of the C8-dG adduct of IQ (dG-C8-IQ), which is most mutagenic at G3 ((2015) Nucleic Acids Res.43, 8340−835126220181). The major type of mutation induced by dG-N2-IQ was targeted G → T, as was reported for dG-C8-IQ. In each site, knockdown of pol κ resulted in an increase in MF, whereas MF was reduced when pol η, pol ι, pol ζ, or Rev1 was knocked down. The reduction in MF was most pronounced when pol η, pol ζ, and Rev1 were simultaneously knocked down and especially when the adduct was located at G3, where MF was reduced by 90%. We conclude that pol κ predominantly performs error-free TLS of the dG-N2-IQ adduct, whereas pols η, pol ζ, and Rev1 cooperatively carry out the error-prone TLS. However, in vitro experiments using yeast pol ζ and κ showed that the former was inefficient in full-length primer extension on dG-N2-IQ templates, whereas the latter was efficient in both error-free and error-prone extensions. We believe that the observed differences between

    In a recent article by Hockett et al (2016 J. Phys. B: At. Mol. Opt. Phys. 49 095602), time delays arising in the context of molecular single-photon ionization are investigated from a theoretical point of view. We argue that one of the central equations given in this article is incorrect and present a reformulation that is consistent with the established treatment of angle-dependent scattering delays (Eisenbud 1948 PhD Thesis Princeton University; Wigner 1955 Phys. Rev. 98 145-7 Smith 1960 Phys. Rev. 118 349-6 Nussenzveig 1972 Phys. Rev. D 6 1534-42).

    Defects in the uvsI gene of Aspergillus nidulans resulted in high UV sensitivity and reductions of spontaneous and UV-induced reversion of certain alleles, uvsl;uvsA double mutants exhibited high methyl methane sulfonate (MMS)-sensitivity in contrast to the slight sensitivity of the component single mutants. Using such a double mutant as recipient, a clone complementing uvsI501 has been isolated from a chromosome III specific library. The deduced amino acid sequence from the 1.1-kb sequenced region, a part of the 5.2-kb DNA fragment showing uvsI-complementing activity, had a 62% identity with REV3 of yeast. Disruptants of the cloned gene demonstrated the same level of sensitivity to UV light as uvsI and failed to complement uvsI501 in heterozygous diploids.

    The goal of this article is to review the progress of three-electron spin qubits from their inception to the state of the art. We direct the main focus towards the exchange-only qubit (Bacon et al 2000 Phys. Rev. Lett. 85 1758-61, DiVincenzo et al 2000 Nature 408 339) and its derived versions, e.g. the resonant exchange (RX) qubit, but we also discuss other qubit implementations using three electron spins. For each three-spin qubit we describe the qubit model, the envisioned physical realization, the implementations of single-qubit operations, as well as the read-out and initialization schemes. Two-qubit gates and decoherence properties are discussed for the RX qubit and the exchange-only qubit, thereby completing the list of requirements for quantum computation for a viable candidate qubit implementation. We start by describing the full system of three electrons in a triple quantum dot, then discuss the charge-stability diagram, restricting ourselves to the relevant subsystem, introduce the qubit states, and discuss important transitions to other charge states (Russ et al 2016 Phys. Rev. B 94 165411). Introducing the various qubit implementations, we begin with the exchange-only qubit (DiVincenzo et al 2000 Nature 408 339, Laird et al 2010 Phys. Rev. B 82 075403), followed by the RX qubit (Medford et al 2013 Phys. Rev. Lett. 111 050501, Taylor et al 2013 Phys. Rev. Lett. 111 050502), the spin-charge qubit (Kyriakidis and Burkard 2007 Phys. Rev. B 75 115324), and the hybrid qubit (Shi et al 2012 Phys. Rev. Lett. 108 140503, Koh et al 2012 Phys. Rev. Lett. 109 250503, Cao et al 2016 Phys. Rev. Lett. 116 086801, Thorgrimsson et al 2016 arXiv:1611.04945). The main focus will be on the exchange-only qubit and its modification, the RX qubit, whose single-qubit operations are realized by driving the qubit at its resonant frequency in the microwave range similar to electron spin resonance. Two different types of two-qubit operations are presented for the exchange

    The scaffold protein X-ray repair cross-complementing 1 (XRCC1) interacts with multiple enzymes involved in DNA base excision repair and single-strand break repair (SSBR) and is important for genetic integrity and normal neurological function. One of the most important interactions of XRCC1 is that with polynucleotide kinase/phosphatase (PNKP), a dual-function DNA kinase/phosphatase that processes damaged DNA termini and that, if mutated, results in ataxia with oculomotor apraxia 4 (AOA4) and microcephaly with early-onset seizures and developmental delay (MCSZ). XRCC1 and PNKP interact via a high-affinity phosphorylation-dependent interaction site in XRCC1 and a forkhead-associated domain in PNKP. Here, we identified using biochemical and biophysical approaches a second PNKP interaction site in XRCC1 that binds PNKP with lower affinity and independently of XRCC1 phosphorylation. However, this interaction nevertheless stimulated PNKP activity and promoted SSBR and cell survival. The low-affinity interaction site required the highly conserved Rev1-interacting region (RIR) motif in XRCC1 and included three critical and evolutionarily invariant phenylalanine residues. We propose a bipartite interaction model in which the previously identified high-affinity interaction acts as a molecular tether, holding XRCC1 and PNKP together and thereby promoting the low-affinity interaction identified here, which then stimulates PNKP directly. © 2017 by The American Society for Biochemistry and Molecular Biology, Inc.

  13. Comment on "Many-body localization in Ising models with random long-range interactions"

    2017-11-01

    This Comment is dedicated to the investigation of many-body localization in a quantum Ising model with long-range power-law interactions r-α, relevant for a variety of systems ranging from electrons in Anderson insulators to spin excitations in chains of cold atoms. It has earlier been argued [arXiv:cond-mat/0611387 (2005); Phys. Rev. B 91, 094202 (2015), 10.1103/PhysRevB.91.094202] that this model obeys the dimensional constraint suggesting the delocalization of all finite-temperature states in the thermodynamic limit for α ≤2 d in a d -dimensional system. This expectation conflicts with the recent numerical studies of the specific interacting spin model of Li et al. [Phys. Rev. A 94, 063625 (2016), 10.1103/PhysRevA.94.063625]. To resolve this controversy we reexamine the model of Li et al. [Phys. Rev. A 94, 063625 (2016), 10.1103/PhysRevA.94.063625] and demonstrate that the infinite-temperature states there obey the dimensional constraint. The earlier developed scaling theory for the critical system size required for delocalization is extended to small exponents 0 ≤α ≤d . The disagreements between the two works are explained by the nonstandard selection of investigated states in the ordered phase in the work of Li et al. [Phys. Rev. A 94, 063625 (2016)type="doi" specific-use="suppress-display">10.1103/PhysRevA.94.063625].

    In a recent paper, Bonitz, Pehlke, and Schoof [Phys. Rev. E10.1103/PhysRevE.87.033105 87, 033105 (2013)], hereafter referred to as BPS, have raised some points against the Shukla-Eliasson attractive potential [P. K. Shukla and B. Eliasson, Phys. Rev. Lett.0031-900710.1103/PhysRevLett.108.165007 108, 165007 (2012); P. K. Shukla and B. Eliasson, Phys. Rev. Lett.0031-900710.1103/PhysRevLett.108.219902 108, 219902(E) (2012); P. K. Shukla and B.

Our objective here is to discuss the insufficiency of the BPS reasoning concerning the applicability of the linearized quantum hydrodynamic theory, as well as to point out the shortcomings in BPS’s arguments and to suggest how to salvage BPS’s density functional theory and simulations, which have failed to produce results that correctly match with that of Shukla and Eliasson.

    2007-07-01

    For thousands of years, all cultures of man have described and researched life energy, whether they called it Qi, Chi, Prana, Od or Orgon. Since Rupert Sheldrake published his theory of morphogenetic fields, the subject has been accessible to the population in general and is contributing to the decline of the current paradigm of science. Knowledge that seamed indisputable since the time of Newton and Descartes is waning, and science must restructure itself on quite a different basis. Einstein, too, is becoming history. The book spans the discoveries of Lord Kelvin to Nikola Tesla to Prof. Dr.-Ing. K. Meyl whose potential eddy theory leads to a new understanding of the world. The key to this is the neutrino, and the fundamentals of neutrino physics are quite simple: At every moment, more than 60 thousand millions of neutrinos flow through us, controlling everything that exists. In his book, author Walter Haege shows how we can all utilise this indispensable neutrino power. It is a book for everyday practice, an indispensable reference manual for all those who intend a radical change in their view of the world and their way of living. (orig.) [German] Seit Jahrtausenden wird in allen Kulturen jene Energie beschrieben und erforscht, die uns steuert und unsere Zeit am Leben erhaelt, jene Energie mit den vielen Namen, von denen uns die bekanntesten, Qi, Chi, Prana, Od oder Orgon vielleicht gelaeufig sind. Seit Rupert Sheldrake und seiner wieder aufgegriffenen Theorie vom morphogenetischen Feld ist dieses Thema grossen Bevoelkerungskreisen neu zugaenglich geworden und traegt dazu bei, dass das jetzige Paradigma der Wissenschaften seinem Ende zugeht. Unser gesichertes Wissen, seit Newton und Descartes scheinbar unumstoesslich, geht dahin und die Wissenschaft muss sich auf gaenzlich anderer Grundlage neu formieren. Auch Einstein wird Geschichte. Die Wirbelphysik Lord Kelvins fuehrt uns ueber die sensationellen Entdeckungen Nikola Teslas zu dem Physiker Prof. Dr.-Ing. K. Meyl, der uns mit seiner Theorie der Potenzialwirbel zu einem neuen Weltverstaendnis fuehrt. Der Schluessel dazu heisst Neutrinos, wobei die Grundlage der Neutrinophysik gaenzlich einfach zu verstehen ist: Mehr als 60 Milliarden Neutrinos pro Sekunde und Quadratzentimeter - aus dem Weltraum kommend - durchfliessen uns und steuern alles was ist. Walter Haege zeigt in diesem Buch praktisch auf, wie jeder von uns diese so notwendige Neutrino-Energie selbst nutzen kann. Es Ist deshalb ein Praxisbuch, dessen Inhalt unverzichtbar fuer jenen Menschen ist, der seine Sicht der Welt und damit sein gesamtes Leben radikal auf neue Fuesse stellen will. (orig.)

    Apart from calculating the strength of pipeline components planning and design are the most important tasks on the areas of apparatus manufacturing, fluid engineering, process engineering and thermal engineering. It is therefore necessary that the flow diagrams of a plant are clearly understandable and in accordance with the technical rules even in the early stages of planning. This book concentrates on steel pipeline which are not laid underground but of the type used mostly in industrial applications. The pictures and equations provided can be used for the design of pipelines, tables and diagrams are given to facilitate estimation of elasticity, pipeline pressure losses and insulating thicknesses. An overview of the equations is given at the end of the book. Many examples facilitate learning. (orig.) [de

    The Stockpile Stewardship Program (SSP) is an integrated technical program for maintaining the safety, surety, and reliability of the U.S. nuclear stockpile. The SSP uses nuclear test data, computational modeling and simulation, and experimental facilities to advance understanding of nuclear weapons. It includes stockpile surveillance, experimental research, development and engineering programs, and an appropriately scaled production capability to support stockpile requirements. This integrated national program requires the continued use of experimental facilities and programs, and the computational capabilities to support these programs. The Advanced Simulation and Computing Program (ASC) is a cornerstone of the SSP, providing simulation capabilities and computational resources that support annual stockpile assessment and certification, study advanced nuclear weapons design and manufacturing processes, analyze accident scenarios and weapons aging, and provide the tools to enable stockpile Life Extension Programs (LEPs) and the resolution of Significant Finding Investigations (SFIs). This requires a balance of resources, including technical staff, hardware, simulation software, and computer science solutions.

    International Nuclear Information System (INIS)

    Hock, B.; Elstner, E.F.

    1988-01-01

    The book deals with accidentally or purposefully induced harmful effects on plants, i.e. eukariyotes and fungi, with emphasis being placed on chemicals as the main pollutants. After discussing the quantification of damage as a prerequisite for detecting, defining, and possibly preventing, damage to plants by toxic substances in the environment, the second part of the book deals with the harmful effects that are purposefully induced, for example in agriculture or horticulture, by employment of pesticides (herbicides or fungicides). In this context, all aspects of uptake, metabolism, and detoxication are discussed, especially referring to the molecular conditions of relevance to a selective elimination of metabolic or developmental processes in the plants, which is explained by the effects of pesticides and antibiotics. Injuries caused by autogenous substances in the plants, upon exceeding a certain amount or dose are also explained, together with effects of physical factors (as e.g. ionizing radiation), or biogenic factors (as e.g. parasites).

    The field of nuclear medicine is undergoing rapid expansion, and is evolving into diagnostic molecular imaging. During recent years, dual-modality imaging with PET/CT has gained acceptance and this is currently the fastest-growing technique for oncological imaging applications. The glucose analogue FDG has held its place in diagnostic oncology, assessment of myocardial viability and diagnosis of neuro-degenerative disorders. Peptides have become even more important as imaging agents. The accuracy of hepatobiliary scintigraphy has been enhanced by cholecystokinin. The use of ACE inhibitors in the evaluation of renovascular hypertension has become the standard in renography. New instrumentation has led to faster scanners, and computer development to better image processing software. Automatic processing is more common, and standardization of protocols can be accomplished easily. The field of gene imaging has progressed, although routine clinical applications are not yet available. The present text, supplemented with many detailed and informative illustrations, represents an adjunct to the standard knowledge of diagnostic nuclear medicine and provides both the student and the professional with an overview of developments during the past decade.

    The scientific basic disciplines of physics and chemistry are the beginning of all medical teaching. They are suitable to clarify medical and biochemical problems in their causality by means of their own thinking methodics as well as by the information provided. This book attempts to point out the relationships of physics, radiology and chemistry to neighbouring disciplines, especially to practical medicine. Greater importance must naturally be given here to the examples of individual fundamental facts than to the conveying of pure theory from books. The statements and questions on self control ordered according to chapter represent a minimum learning for the students which can be extended as required. (orig./ORU) [de

    Inorganic chemistry is a branch of considerable economic and technical importance. Apart from supplying the market with metals, fertilizers, building materials, pigments and glass it is one of the major suppliers of process materials to the organic chemical industry. Many modern products of other industrial sectors (video tapes, optical fibers or silicon chips) could not have been developed and manufactured without the achievements of industrial inorganic chemistry. The publication is the first of its kind to give a compact description of the inorganic chemistry sector. A clearly arranged survey facilitates access to production processes, economic aspects, ecological implications, energy consumption and raw material consumption as well as to many other data and facts. Due to its clear arrangement and the combination of technical and economic facts the book is a valuable source of information. (orig./EF) [de

  15. Teaching atlas of mammography. 2. rev. ed.

    International Nuclear Information System (INIS)

    Tabar, L.; Dean, P.B.

    1985-01-01

    The purpose of this Atlas is to teach radiologists how to analyze mammograms and arrive at the correct diagnosis through proper evaluation of the findings. The illustrated cases cover practically the entire spectrum of breast abnormalities. They are based upon referred patient material as well as 80000 mammographic screening examinations. There are two basic steps in the interpretation of mammograms: perception and analysis. Since the greatest benefit of mammography lies in the detection of breast carcinoma in its earliest possible stages, every mammogram must be systematically surveyed for the subtle hints of malignancy. Perception is taught in this Atlas by describing a method for systematic viewing. The reader is then provided with a series of mammograms with obscure lesions to encourage practice with this method. With the help of a coordinate system, the lesions can be precisely located. Practice in perception continues throughout the Atlas. After detecting an abnormality on the mammogram, the diagnosis can be reached through a careful analysis of the X-ray signs. Additional projections, coned-down compression and magnetification views provide further help in this analytic workup. Rather than starting with the diagnosis and demonstrating typical findings, the approach of this Atlas is to teach the reader how to analyze the image and reach the correct diagnosis through proper evaluation of the X-ray signs. Prerequisites for the perception and evaluation of the X-ray signs are optimum technique, knowledge of anatomy and understanding of the pathological processes leading to the mammographic appearances.

    With the last changes in the Ordinance Concerning the Transport of Hazardous Goods two regulations which are important for the carrying trade were introduced: 1. The conveyer must train the driver. He must only employ reliable drivers. 2. The driver must participate in a training course (as of July 1, 1991). These obligations, which already existed in the past in regard to the transport of nuclear fuel, have been extended to include the transport of other radioactive materials. In part I the book deals with basic training courses for parcelled goods, and part II goes into the special knowledge which is required of drivers of radioactive materials. The parts consist of the following sections: 1. General regulations, 2, Responsibility when transporting hazardous goods, 3. General danger features, 4. Information on dangers and their designation, 5. The vehicle's equipment and carrying out the transport, 6. Measures for avoiding accidents. At the end of each section the participant in the course finds a series of questions which pertain to the subject matter just treated so that he can test his own learning performance. So as to make things easier for the trainee, the corect answers are listed in the appendix. As a supplementary section on radioactive materials, part II offers additional detailed explanations by experts in the field on the features of radioactive materials and the dangers they pose. In the margin - next to the instructory text - the key words are given so that the right place in the text of the instruction manual can be readily found. These key words are compiled in the appendix to form an index. (orig./HP) [de

    The preliminary design for a three-bladed cross-flow rotor for a reference marine hydrokinetic turbine is presented. A rotor performance design code is described, along with modifications to the code to allow prediction of blade support strut drag as well as interference between two counter-rotating rotors. The rotor is designed to operate in a reference site corresponding to a riverine environment. Basic rotor performance and rigid-body loads calculations are performed to size the rotor elements and select the operating speed range. The preliminary design is verified with a simple finite element model that provides estimates of bending stresses during operation. A concept for joining the blades and support struts is developed and analyzed with a separate finite element analysis. Rotor mass, production costs, and annual energy capture are estimated in order to allow calculations of system cost-of-energy. Evaluation Only. Created with Aspose.Pdf.Kit.

    In hierarchical searches for continuous gravitational waves, clustering of candidates is an important post-processing step because it reduces the number of noise candidates that are followed up at successive stages [J. Aasi et al., Phys. Rev. Lett. 88, 102002 (2013), 10.1103/PhysRevD.88.102002; B. Behnke, M. A. Papa, and R. Prix, Phys. Rev. D 91, 064007 (2015), 10.1103/PhysRevD.91.064007; M. A. Papa et al., Phys.

Previous clustering procedures bundled together nearby candidates ascribing them to the same root cause (be it a signal or a disturbance), based on a predefined cluster volume. In this paper, we present a procedure that adapts the cluster volume to the data itself and checks for consistency of such volume with what is expected from a signal. This significantly improves the noise rejection capabilities at fixed detection threshold, and at fixed computing resources for the follow-up stages, this results in an overall more sensitive search. This new procedure was employed in the first Einstein@Home search on data from the first science run of the advanced LIGO detectors (O1) [LIGO Scientific Collaboration and Virgo Collaboration, arXiv:1707.02669 [Phys.

    We report the ratio of double-to-single photoionization of He at several photon energies from 2 to 12 keV. By time-of-flight methods, we find a ratio consistent with an asymptote at 1.5%±0.2%, essentially reached by hν∼4 keV. Fair agreement is obtained with older shake calculations of Byron and Joachain [Phys. Rev. 164, 1 (1967)], of Aberg [Phys. Rev. A 2, 1726 (1970)], and with recent many-body perturbation theory (MBPT) of Ishihara, Hino, and McGuire [Phys. Rev. A 44, 6980 (1991)]. The result lies below earlier MPBT calculations by Amusia et al. [J. Phys. B 8, 1248 (1975)] (2.3%), and well above semiempirical predictions of Samson [Phys. Rev. Lett. 65, 2861 (1990)], who expects no asymptote and predicts σ(He 2+ )/σ(He + )=0.3% at 12 keV

The results are compared to the calculations performed in the CGC framework and it is demonstrated that the LO CGC results for the classical field are reproduced in our calculations. Possible applications of the NLO solution in the effective action and CGC frameworks are discussed as well. (orig.)

    heat transfer in rate attainment and the much greater role of wall effects in heat transfer when the melt pool is not agitated. The DM100 melter used for the present tests has a surface area of 0.108 m{sup 2}, which is approximately 5 times larger than that of the DM10 (0.021 m{sup 2}) and approximately 11 times smaller than that of the DM1000 (1.2 m{sup 2}) (the DM1000 has since been replaced by a pilot-scale prototypical HLW melter, designated the DM1200, which has the same surface area as the DM1000). Testing on smaller melters is the most economical method for obtaining data over a wide range of operating conditions (particularly at extremes) and for guiding the more expensive tests that are performed at pilot-scale. Thus, one objective of these tests was to determine whether the DM100 melters are sufficiently large to reproduce the un-bubbled melt rates observed at the DM1000 scale, or to determine the extent of any off-set. DM100-scale tests can then be used to screen feed chemistry variations that may serve to increase the un-bubbled production rates prior to confirmation at pilot scale. Finally, extensive characterization data obtained on simulated HLW melter feeds formed from various glass forming additives indicated that there may be advantages in terms of feed rheology and stability to the replacement of some of the hydroxides by carbonates. A further objective of the present tests was therefore to identify any deleterious processing effects of such a change before adopting the carbonate feed as the baseline. Data from the WVDP melter using acidified (nitrated) feeds, and without bubbling, showed productions rates that are higher than those observed with the alkaline RPP feeds at the VSL. Therefore, the effect of feed acidification on production rate also was investigated. This work was performed under Test Specification, 'TSP-W375-00-00019, Rev 0, 'HLW-DM10 and DM100 Melter Tests' dated November 13, 2000 and the corresponding Test Plan. It

    Density functional theory (DFT) calculations show that self-interstitial atom (SIA) defects in nonmagnetic body-centered-cubic (bcc) metals adopt strongly anisotropic configurations, elongated in the direction [S. Han et al., Phys. Rev. B 66, 220101 (2002), 10.1103/PhysRevB.66.220101; D. Nguyen-Manh et al., Phys. Rev. B 73, 020101 (2006), 10.1103/PhysRevB.73.020101; P. M. Derlet et al., Phys. Rev. B 76, 054107 (2007), 10.1103/PhysRevB.76.054107; S. L. Dudarev, Annu. Rev. Mater. Res. 43, 35 (2013), 10.1146/annurev-matsci-071312-121626]. Elastic distortions, associated with such anisotropic atomic structures, appear similar to distortions around small prismatic dislocation loops, although the extent of this similarity has never been quantified. We derive analytical formulas for the dipole tensors of SIA defects, which show that, in addition to the prismatic dislocation looplike character, the elastic field of a SIA defect also has a significant isotropic dilatation component. Using empirical potentials and DFT calculations, we parametrize dipole tensors of defects for all the nonmagnetic bcc transition metals. This enables a quantitative evaluation of the energy of elastic interaction between the defects, which also shows that in a periodic three-dimensional simple cubic arrangement of crowdions, long-range elastic interactions between a defect and all its images favor a orientation of the defect.

    We perform high-resolution N-body simulations for f(R) gravity based on a self-adaptive particle-mesh code MLAPM. The chameleon mechanism that recovers general relativity on small scales is fully taken into account by self-consistently solving the nonlinear equation for the scalar field. We independently confirm the previous simulation results, including the matter power spectrum, halo mass function, and density profiles, obtained by Oyaizu [Phys. Rev. DPRVDAQ1550-7998 78, 123524 (2008)10.1103/PhysRevD.78.123524] and Schmidt [Phys. Rev. DPRVDAQ1550-7998 79, 083518 (2009)10.1103/PhysRevD.79.083518], and extend the resolution up to k˜20h/Mpc for the measurement of the matter power spectrum. Based on our simulation results, we discuss how the chameleon mechanism affects the clustering of dark matter and halos on full nonlinear scales.

    In a recent paper [Phys. Rev. A 95, 052118 (2017), 10.1103/PhysRevA.95.052118], the authors claim that our criticism, in Phys. Rev. A 94, 052125 (2016), 10.1103/PhysRevA.94.052125, to some quantum speed limit bounds for open quantum dynamics that appeared recently in literature are invalid. According to the authors, the problem with our analysis would be generated by an artifact of the finite-precision numerical calculations. We analytically show here that it is not possible to have any inconsistency associated with the numerical precision of calculations. Therefore, our criticism of the quantum speed limit bounds continues to be valid.

    The angular momentum basis method is introduced to solve the inclusive breakup problem within the model proposed by Ichimura, Austern, and Vincent [Phys. Rev. C 32, 431 (1985), 10.1103/PhysRevC.32.431]. This method is based on the geometric transformation between different Jacobi coordinates, in which the particle spins can be included in a natural and efficient way. To test the validity of this partial wave expansion method, a benchmark calculation is done comparing with the one given by Lei and Moro [Phys. Rev. C 92, 044616 (2015), 10.1103/PhysRevC.92.044616]. In addition, using the distorted-wave Born approximation version of the IAV model, applications to 7Li+58Ni reactions at energies around Coulomb barrier are presented and compared with available data.

A 93, 052512 (2016), 10.1103/PhysRevA.93.052512] introduced orbitals within a mean-field framework that produce energy levels similar to Hartree-Fock orbital energies, therefore he also claims that conventional analyses based on Koopmans' theorem are possible in 1RDM functional theory. In this Comment, we demonstrate that both claims are unfounded.

Beams 15, 051301 (2012PRABFM1098-440210.1103/PhysRevSTAB.15.051301] have proposed a set of parameters for a TeV-scale collider based on plasma wakefield accelerator principles. In particular, it is sugested that the luminosities greater than 10^{34}  cm^{-2} s^{-1} are attainable for an electron-positron collider. In this Comment we dispute this set of parameters on the basis of first principles. The interactions of accelerating beam with plasma impose fundamental limitations on beam properties and, thus, on attainable luminosity values.

    We examine the execution of general U(1) transformations on programmable quantum processors. We show that, with only the minimal assumption of availability of copies of the 1-qubit program state, the apparent advantage of existing schemes proposed by G. Vidal et al. [Phys. Rev. Lett. 88, 047905 (2002)] and M. Hillery et al. [Phys. Rev. A 65, 022301 (2003)] to execute a general U(1) transformation with greater probability using complex program states appears not to hold

    We show that in the protocol proposed in Phys. Rev. A 91, 042306 (2015), 10.1103/PhysRevA.91.042306, a dishonest sender can always ensure with certainty that the receiver fails to get the secret message. Thus the security requirement of oblivious transfer is not met. This security problem also makes the protocol unsuitable for serving as a building block for 1-out-of-2 oblivious transfer.

We demonstrate, using general arguments and explicit examples, that whenever the correlation length is finite, local observables converge exponentially fast in the cluster size Lc within cellular dynamical mean field theory. This is a faster rate of convergence than the 1/ L2c behavior of the dynamical cluster approximation, thus refuting the central assertion of their Comment.

    We experimentally demonstrate that violations of Bell's inequalities for two-photon polarization-entangled states with colored noise are extremely robust, whereas this is not the case for states with white noise. Controlling the amount of noise by using the timing compensation scheme introduced by Kim et al. [Phys. Rev. A 67, 010301(R) (2003)], we have observed violations even for states with very high noise, in excellent agrement with the predictions of Cabello et al. [Phys. Rev. A 72, 052112 (2005)

APLRAAN1050-294710.1103/PhysRevA.81.011804 81, 011804(R) (2010)] have recently constructed a mathematical proof that the Maxwell's fish-eye lens provides perfect imaging of electromagnetic waves without negative refraction. In this comment, we argue that the unlimited resolution is an artifact of having introduced an unphysical drain at the position of the geometrical image. The correct solution gives focusing consistent with the standard diffraction limit.

  10. Quantum Secure Direct Communication Based on Authentication

    International Nuclear Information System (INIS)

    We propose two schemes of quantum secure direct communication (QSDC) combined ideas of user authentication [Phys. Rev. A 73 (2006) 042305] and direct communication with dense coding [Phys. Rev. A. 68 (2003) 042317]. In these protocols, the privacy of authentication keys and the properties of the EPR pairs not only ensure the realization of identity authentication but also further improve the security of communication, and no secret messages are leaked even if the messages were broken.

    Yagasaki et al. [Phys. Rev.

We point out that neither two distinct liquids nor criticality are demonstrated in this simulation study. Instead, the illustrated trajectory is consistent with coarsening behaviors analyzed and predicted in earlier work by others.
