  2. Safety and design impact of hurricane Andrew

    International Nuclear Information System (INIS)

    Turkey Point completed the IPE in June of 1991. Hurricane Andrew landed at Turkey Point on August 24, 1992. Although the safety related systems, components and structures were not damaged by the Hurricane Andrew, certain nonsafety related components and the neighboring fossil plant sustained noticeable damage. Among the major components that were nonsafety related but would affect the PRA of the plant included the service water pumps and the high tower. This paper discusses the safety and design impact of Hurricane Andrew on Turkey Point Nuclear Power Plant. The risk of hurricanes on the interim and evolving plant configurations are briefly described. The risk of the plant from internal events as a result of damage incurred during Hurricane Andrew are discussed. The design change as the result of Hurricane Andrew and its impact on the PRA are presented. (author)

  3. Obituary: Andrew Stephen Wilson, 1947-2008

    2009-01-01

    On 24 May 2008, Andrew Stephen Wilson passed away at the age of 61, in his home in Silver Spring, Maryland, from complications resulting from a painful spinal illness. Andrew was arguably one of the first truly multi-wavelength astronomers of his generation. His scientific work on active galactic nuclei [AGN] spanned the entire electromagnetic spectrum from the radio to the X-rays. Andrew was born in Doncaster, Yorkshire, England, on 26 March 1947. He was the younger of two brothers whose births were separated by the Second World War. His father, Norman, came from a relatively affluent family who were coal merchants. His mother, Mary, came from a less comfortable background, one of seven children, daughter of a skilled cabinet maker/French polisher, who went through a very hard time during the depression. As a teacher, she placed enormous value on hard work and education as a way of gaining advancement in life. When Andrew was four, the family moved to Skipton, a nice market town in the Yorkshire dales. Andrew went to a small village school until age eleven when he entered Ermysted's Grammar School. He was an enthusiastic soccer and cricket player. He never lost his enthusiasm for soccer and supported the local soccer team, Leeds United, for all his life. Andrew also followed the Yorkshire county cricket team. Andrew's interest in astronomy stemmed from the fact that at Ermysted's Grammar School someone donated a four-inch refracting telescope, so he and his friends used to go back in the evenings to investigate the rings of Saturn, the moons of Jupiter, and various nebulae. While an undergraduate at Cambridge, Andrew joined the astronomy club and ground an 8-inch mirror by hand as a part of a telescope that he set up in the backyard of his parents' house. Andrew spent hours observing with this telescope, and it was the wonder of the family. At Cambridge, Andrew obtained his bachelor's degree with first-class honors in 1969. During a short visit in London with his

  5. Obituary: Andrew Lange (1957-2010)

    2011-12-01

    The worlds of physics and astrophysics were stunned to learn on 22 January 2010 that Andrew Lange, the Marvin L. Goldberger Professor of Physics at Caltech, had taken his own life the night before. He had succumbed to the severe depression that he had suffered from for many years, unbeknownst to even his closest colleagues. Lange will perhaps be best remembered as the co-leader of Boomerang, the balloon-borne experiment that provided the first high-angular-resolution map of the cosmic microwave background (CMB). And while this was certainly his most notable achievement, Andrew amassed a record of accomplishment as an instrumentalist, leader, mentor, and communicator that extended much further. Andrew was born in Urbana, Illinois on July 23, 1957, the son of an architect and a librarian, and raised primarily in Connecticut. His family and early friends remember him as a serious and extremely intelligent child and young man. Andrew Lange's lifelong interest in the CMB was nurtured as an undergraduate at Princeton University by David Wilkinson, and he recalled fondly a summer spent working with John Mather at Goddard Space Flight Center. Andrew Lange went to graduate school in physics at Berkeley where he worked in Paul Richards' group. Although his thesis project, the Berkeley-Nagoya rocket experiment, showed an anomalous sub-millimeter excess in the CMB spectrum that was shortly thereafter shown by a later flight of the same rocket and COBE-FIRAS to be incorrect, Lange's talents were recognized by the physics department at Berkeley who appointed him shortly after his PhD (1987) to their faculty. While on the Berkeley faculty, Andrew obtained early detections of the Sunyaev-Zeldovich effect, upper limits to small-angle CMB fluctuations, and important infrared constraints to the interstellar medium. He also led a pioneering instrument operating 300 mK detectors for a small infrared satellite experiment. This early work showed high ambition and daring, and it pioneered

  7. Wie was Andrew Murray (1828-1917 in werklikheid?

    Directory of Open Access Journals (Sweden)

    T.G. Mahne

    1999-08-01

    Full Text Available Murray (1828-1917 was an emissary of God. In the Dutch Reformed Church in South Africa, where he served as a full time minister for fifty eight years, he was elected Moderator six times. His influence, however, was not limited to the Dutch Reformed Church. Of the two hundred and fifty books (more than 20 000 pages he wrote, some were translated into more than twenty languages. In spite of his intention not to write theological works, Murray was granted a doctorate degree in Theology by the University of Aberdeen in 1898. He was a man of prayer who published approximately thirty books about prayer. Murray, a mystic and peifectionist, was reared in an extremely legalistic home. As a student he joined the Secor Dabar association which was an offspring of the legalistic Reveil movement in the first half of the nineteenth century. At the age of roundabout 65, Murray was impressed by the writings of William Law (1686-1761, which fitted his mindset like a glove. But who was Andrew Murray actually? Other similar questions concerning his influence in the Dutch Reformed Church are equally important. First and foremost however: Who was this man? Was he possibly a "tossed salad" theologian? Still today we find traces of Murrayism in the Dutch Reformed Church. Fortunately his full-time service of fifty eight years has left behind a positive heritage of Scottish Calvinism.

    The fast beam losses in the order of 1 ms are expected to be a potential major luminosity limitation for higher beam energies after the LHC long shutdown (LS1). Therefore a Quench Test is planned in the winter 2013 to estimate the quench limit in this timescale and revise the current models. This experiment was devoted to determination the LHC Transverse Damper (ADT) as a system for fast losses induction. A non-standard operation of the ADT was used to develop the beam oscillation instead of suppressing them. The sign flip method had allowed us to create the fast losses within several LHC turns at 450 GeV during the previous test (26th March 2012). Thus, the ADT could be potentially used for the studies of the UFO ("Unidentied Falling Object") impact on the cold magnets. Verification of the system capability and investigations of the disturbed beam properties were the main objectives of this MD. During the experiment, the pilot bunches of proton beam were excited independently in the horizontal and vertical ...

  3. Impact of Hurricane Andrew on FPL generation facilities

    International Nuclear Information System (INIS)

    In the pre-dawn hours of August 25, 1992, Hurricane Andrew made landfall in southern Dade County, Florida. The storm approached directly from the east and moved rapidly across the State and into the Gulf of Mexico. Andrew's intense winds caused unprecedented devastation to structures and facilities in its path. Not surprisingly, Florida Power and Light's (FPL) generation, transmission and distribution facilities in south Florida also suffered extensive damage. Two of FPL's electrical generating sites were located in the direct path of the storm and received its full brunt. This paper presents a review of the damage sustained by those plants, an overview of the unique recovery challenges encountered and a summary of the lessons learned from this experience

    The purpose of this MD is to measure the octupole current thresholds for stability for a single bunch, and then make an immediate comparison (with the same operational settings) for a train of 72 bunches separated by 25ns. From theory, the expected thresholds should be similar. Any discrepancy between the two cases will be of great interest as it could indicate the presence of additional mechanisms that contribute to the instability threshold, for example electron cloud.

    A series of laboratory experiments were performed on three reservoir core samples selected from two plot wells to confirm the likelihood of sand production during the completion phase of the planned Andrew horizontal wells, and to perform risk analysis of formation failure at the time of underbalance perforation, and expected producing conditions. CT scans revealed no perforation failure, and the core samples did not show any propensity to produce sand during single-phase oil flow. Transient sand production was observed when water cut was introduced, but sand production declined as the percentage of water cut was increased. There was no evidence of sand production in the core samples during depletion testing either, and the wells were subsequently completed with perforated cemented liners without sand control. No sand problems have been encountered in two years of production, with some wells in water cut and declined reservoir pressure of 200 psi. 8 refs., 3 tabs., 5 figs.

    CERN Document Server

    2012-01-01

    The LHC RF/LLRF system is currently setup for extremely stable RF voltage to minimize transient beam loading eects. The present scheme cannot be extended beyond nominal beam current since the demanded power would push the klystrons to saturation. For beam currents above nominal (and possibly earlier), the cavity phase modulation by the beam will be not be corrected (transient beam loading), but the strong RF feedback and One-Turn Delay feedback will still be active for loop and beam stability in physics. To achieve this, the voltage set point will be adapted for each bunch. The goal of this MD was to test an iterative algorithm that would adjust the voltage set point to achieve the optimal phase modulation for klystron forward power considerations.

    Andrew Sexton Gray was born in Limerick, Ireland, medically trained in Dublin, and was assistant to William Wilde, the distinguished oculist and aurist. He migrated to Victoria in 1859, was surgeon to a railway's construction company, then in 1862 began practice as a surgeon and oculist in Melbourne. In 1863 he founded a charitable eye and ear hospital, and had a very active, long life devoted mostly to ophthalmology. The hospital progressively expanded and became the centre for training for many ophthalmologists, as well as the nucleus for the cohesion of Victorian ophthalmology. History shows Andrew Sexton Gray to have been a founder of Australian ophthalmology. PMID:3914312

    In this paper, we present an improved attack algorithm to find two-block collisions of the hash function MD5. The attack uses the same differential path of MD5 and the set of sufficient conditions that was presented by Wang et al. We present a new technique which allows us to deterministically fulfill restrictions to properly rotate the differentials in the first round. We will present a new algorithm to find the first block and we will use an algorithm of Klima to find the second block. To o...

    2012-01-01

    UFOs ("Unidentified Falling Objects") are expected to be one of the major known performance limitation of the LHC. In this MD, the production mechanism and the dynamics of UFOs at the injection kicker magnets (MKIs) and the tune kicker magnets (MKQs) were studied. This was done by pulsing the MKIs and MKQs on a gap in the partly filled machine. During the MD, in total 58 UFO-type beam loss patterns were observed directly after pulsing the MKIs. None were observed after pulsing the MKQs, which provides important input for possible mitigation strategies. The temporal and spatial distribution of the UFO events could be determined by using a dedicated BLM Study Buffer, the implications for the UFO dynamics are discussed.

  18. Batch By Batch Longitudinal Emittance Blowup MD

    CERN Document Server

    2012-01-01

    The transverse bunch emittance increases significantly at 450 GeV from the time of injection till the ramp due to IBS. By selectively blowing up the longitudinal emittance of the incoming batch at each injection, it should be possible to reduce the transverse emittance growth rates due to IBS. An MD was conducted on April 22nd 2012 to test the feasibility and performance of the batch-by-batch longitudinal emittance blowup. There were three main goals during the MD. First, to test the developed hardware, firmware, and software for the batch-by-batch blowup. Then, to measure the transverse emittance growth rates of blown-up and "witness" batches to quantify any improvement, and finally to test the ALLInjectSequencer class, which deals with the complicated gymnastics of introducing or masking the new batch to various RF loops.

    The ballistic optics is designed to improve the understanding of optical errors and BPM systematic effects in the critical triplet region. The particularity of that optics is that the triplet is switched off, effectively transforming the triplets on both sides of IR1 and IR5 into drift spaces. Advantage can be taken from that fact to localize better errors in the Q4-Q5-triplet region. During this MD this new optics was tested for the first time at injection with beam 2.

    I agree with Andrew C. Papanicolaou's claim that human beings' cognitive ability can reach to the real world, but don't agree with his claim that the order of this world is akin to our thought. In this commentary paper, I will first defend a recent pragmatic scientific realism called as "entity realism" or "referential realism" which affirms that we are able to reach the real world not by inference but by technological, engineering settings. In the second half of this paper, I will also affirm that our perceptual ability directly reaches the reality too, in referring to the ecological psychology of James J. Gibson. PMID:24986382

  20. Ecological evaluation of proposed dredged material from St. Andrew Bay, Florida

    International Nuclear Information System (INIS)

    The US Army Corps of Engineers (USACE), Mobile District, requested that the Battelle/Marine Sciences Laboratory (MSL) conduct field sampling and chemical and biological testing to determine the suitability of potential dredged material for open ocean disposal. Sediment from St. Andrew Bay was chemically characterized and evaluated for biological toxicity and bioaccumulation of contaminants. The Tier III guidance for ocean disposal testing requires tests of water column effects (following dredged material disposal), deposited sediment toxicity, and bioaccumulation of contaminants from deposited sediment (dredged material). To meet these requirements, the MSL conducted suspended-particulate-phase (SPP) toxicity tests, solid-phase toxicity tests, and bioaccumulation testing on sediment representing potential dredged material from Panama City Harbor. Physical and chemical characterization of sediment to support toxicity and bioaccumulation results was also conducted on both the test and reference sediments. The MSL collected sediment samples from five sites in St. Andrew Bay and one reference site near Lands End Peninsula. The five test sediments and the reference sediment were analyzed for physical and chemical sediment characteristics, SPP chemical contaminants, solid-phase toxicity, SPP toxicity, and bioaccumulation of contaminants

    1988-11-01

    This study investigated the empirical validity of the MacAndrew Alcoholism Scale as a measure of alcohol abuse, marijuana use, and related multiple substance use in a sample of N = 160. Classification accuracy was 45% for alcohol abuse, 48.8% for marijuana use, and 66% for related multiple substance use (n = 12). There were few differences in personality functioning as measured by the California Psychological Inventory between true positives and false negatives. Both groups exhibited adolescent qualities, i.e., irresponsibility, attraction to pleasure seeking, and minor rebelliousness. False negatives appeared to be slightly less impulsive and somewhat less secure about themselves. Both groups were also similar in terms of reported use of alcohol. They used alcohol to enhance a sense of well-being, i.e., to gain pleasure and to reduce dysphoric affect, but not to reduce inhibitions in social relationships. However, true positives tended to use alcohol to help cope with problems in personal relationships, such as rejection. Some limitations of the study, especially in relation to recent formulations of female alcoholism by MacAndrew (1986), were discussed. PMID:3216005

    Magyar, Rudolph J.; Mattsson, Thomas R.

    2009-03-01

    Xenon is not only a technologically important element used in laser technologies, jet propulsion and dental anesthesia, but it is also arguably the simplest material in which to study the metal-insulator transition at high pressure. Because of its closed shell electronic configuration, Xenon is often assumed to be chemically inert, interacting almost entirely through the van der Waals interaction, and at liquid density, is typically modeled well using Leonard-Jones potentials. However, such modeling has a limited range of validity as Xenon is known to form compounds at normal conditions and likely exhibits considerably more chemistry at higher densities when hybridization of occupied orbitals becomes significant. In this talk, we present DFT-MD simulations of shocked liquid Xenon with the goal of developing an improved equation of state. The relative importance of the van der Waals interaction compared to other Coulomb interactions is considered, and estimates of the relative accuracy of various density functionals are quantified. Sandia is a multiprogram laboratory operated by Sandia Corporation, a Lockheed Martin Company, for the United States Department of Energy's National Nuclear Security Administration under contract DE-AC04-94AL85000.

    Full Text Available Prosthetic dentistry involves the replacement of missing and contiguous tissues with artificial substitutes to restore and maintain the oral functions, appearance, and health of the patient. The treatment of edentulous areas with ridge defects poses a challenging task for the dentist. Management of such cases involves a wide range of treatment options comprising mainly of surgical interventions and non surgical techniques such as use of removable, fixed or fixed- removable partial dentures. But each treatment plan undertaken should be customized according to patient needs. A variety of factors such as quality and quantity of existing contiguous hard and soft tissues, systemic condition and economic status of the patient play an important role in treatment planning, clinical outcome and prognosis. This case report presents the restoration of a Seibert′s Class III ridge defect by an economical modification of Andrews Bridge in a 32 Year old patient.

    Prosthetic dentistry involves the replacement of missing and contiguous tissues with artificial substitutes to restore and maintain the oral functions, appearance, and health of the patient. The treatment of edentulous areas with ridge defects poses a challenging task for the dentist. Management of such cases involves a wide range of treatment options comprising mainly of surgical interventions and non surgical techniques such as use of removable, fixed or fixed- removable partial dentures. But each treatment plan undertaken should be customized according to patient needs. A variety of factors such as quality and quantity of existing contiguous hard and soft tissues, systemic condition and economic status of the patient play an important role in treatment planning, clinical outcome and prognosis. This case report presents the restoration of a Seibert's Class III ridge defect by an economical modification of Andrews Bridge in a 32 Year old patient. PMID:25821362

    Vanilla (Vanilla planifolia Andrews (syn. V. fragrans Salisb.), a native of Central America, is the primary source of natural vanillin and plays a major role in the global economy. The gene pool of vanilla is threatened by deforestation and overcollection that has resulted in disappearance of natural habitats and wild species. Continuous vegetative propagation and lack of natural seed set and sufficient variations in the gene pool hamper crop improvement programs. In vitro techniques, one of the key tools of plant biotechnology, can be employed for overcoming specific problems, viz. production of disease-free clones, inducing somaclonal variations, developing hybrids, gene pool conservation, incorporating desired traits by distant hybridization, genetic engineering, etc. However, realization of these objectives necessitates standardization of protocols. This chapter describes the various protocols optimized for crop improvement in Vanilla species. PMID:27108309

  13. Book Review of 'Evolutionary and Interpretive Archaeologies' Edited by Ethan E. Cochrane and Andrew Gardner

    2015-01-01

    Evolutionary and Interpretive Archaeologies, edited by Ethan E. Cochrane and Andrew Gardner, grew out of a seminar at the Institute for Archaeology at University College London in 2007. It consists of 15 chapters by archaeologists who self-identify themselves as practitioners who emphasize the benefits of evolutionary or interpretive approaches to the study of the archaeological record. While the authors' theoretical views are dichotomous, the editors' aim for the book as a whole is not to expound on the differences between these two kinds of archaeology but to bring forward a richer understanding of the discipline and to highlight areas of mutual concern. Some chapters come across as a bit of a sales pitch, but the majority of the contributions emphasize how each approach can be productively used to address the goals of the other. The book seeks to contribute to a mutually beneficial and more productive discipline, and overall, it succeeds in this effort.

  14. General Andrew Wauchope of Niddrie Marischal. A character sketch and brief historical tribute

    Full Text Available Two months after the outbreak of the Anglo-Boer War a series of battles took place which shook Britain. These were Stormberg (10 December1899, Magersfontein (11 December 1899 and Colenso (15 December 1899. All had been reverses for the British army and had taken place within a week which became known as Black Week - a phrase coined by the British Liberal Party politician Asquith. Great Britain was regarded as having the world's most powerful army at the time and the losses suffered against the Boers resulted in humiliation and anguish for the British nation. However, nowhere was the anguish greater than in Scotland for at Magersfontein the Highland Brigade had fared badly suffering severe losses including their commander, Major-General Andrew Wauchope, killed in action. As Conan Doyle put it, "Never has Scotland had a more grievous day than this at Magersfontein. She had always given her best blood with lavish generosity for the Empire, but it may be doubted if any single battle has ever put' so many families of high and low, into mourning from the Tweed to Caithness shore." (Doyle, 1900:24 In the words of biographer William Baird "the empire has lost one of its noblest and best, a hero has gone down to his rest ere his full life's work was done". (Baird, 1902:196 Although these statements may seem somewhat flowery and were expressed during a period of much patriotic fervour, they nevertheless indicate the emotional reaction to Andrew Wauchope's untimely death.

    This note highlights the results obtained during the third so-called ATS MD which took place in 2011. The goal of this MD was extremely challenging, targeting a pre-squeezed beta* of 40 cm in ATLAS and CMS, followed by a telescopic squeeze of these two insertions to finally reach a beta* of 10 cm both at IP1 and IP5. Due to the rather poor machine availability during the MD period, the time initially allocated to the ATS studies was hardly cut by a factor of 2, and "only" the achromatic pre-squeeze down to beta*=40 cm was demonstrated with beam.

    Colliding the beams during the squeeze to profit from Landau damping due to head--on beam-beam and beta--star leveling are two operational modes that may have to be used in a not so distant future at the LHC. This MD aimed at improving the orbit control during the squeeze with much improved handling of orbit feedback references and at evaluating instruments and techniques to maintain the beam in collisions with active feedback on luminosity or beam position. This MD also integrated for the first time synchronized collimator measurements. Comparison of the settings with the previous MD allowed a validation of the long term stability of collide and squeeze.

  1. Charge separation reaction in clusters of polar molecules. MD simulations

    International Nuclear Information System (INIS)

    Rate constant of intermolecular electron transfer (ET) in a photoexcited donor-acceptor model system solvated by a cluster of polar molecules has been expressed in terms of the statistical distribution of the electrostatic potential energy difference between the reacting sites. This distribution has been calculated for a particular case of acetonitrile clusters at ∼ 120 K by MD computer simulation. The MD values of the cluster reorganization energy and the ET rate constant have been compared with the corresponding MD results for the donor-acceptor pair solvated in bulk acetonitrile and with theoretical predictions based on the continuum model.

    2011-12-01

    Quantitifying infiltration rates is a key component of the performance assessment for radioactive waste disposal facilities. In arid regions with scarce infiltration data, this is a challenging problem because of the computational limitations of available numerical implementations to solve water flow and transport equations. This work summarizes methodology and analysis performed to overcome some of these challenges and to generate infiltration scenarios for a low level waste disposal site in Andrews County, Texas. The work presented here includes preparation of a two dimensional finite element model in HYDRUS that includes the cover system and adjacent geologic units, calibration of hydraulic properties and root water uptake parameters based on soft information, preparation of atmospheric forcings based on current and hypothesized future climatic conditions, evaluation of impacts related to temporal and spatial discretization of forcings and model domain, and definition of scenarios for cover degradation and wetter climate conditions. Results of this work include a sensitivity analysis of infiltration rates to changes in boundary conditions under quasi-steady state, evaluation of the impact of temporal discretization of the atmospheric forcings in terms of water balance error and computational efficiency, and the estimation of infiltration rates under different scenarios. Infiltration rates from this work are being incorporated into a transport model to estimate potential radiological doses based on performance assessment modeling analyses. Findings from this work seek to contribute towards robust approaches to estimate infiltration in arid regions.

  16. Genomewide scan for adaptive differentiation along altitudinal gradient in the Andrew's toad Bufo andrewsi.

    2016-08-01

    Recent studies of humans, dogs and rodents have started to discover the genetic underpinnings of high altitude adaptations, yet amphibians have received little attention in this respect. To identify possible signatures of adaptation to altitude, we performed a genome scan of 15 557 single nucleotide polymorphisms (SNPs) obtained with restriction site-associated DNA sequencing of pooled samples from 11 populations of Andrew's toad (Bufo andrewsi) from the edge of the Tibetan Plateau, spanning an altitudinal gradient from 1690 to 2768 m.a.s.l. We discovered significant geographic differentiation among all sites, with an average FST   = 0.023 across all SNPs. Apart from clear patterns of isolation by distance, we discovered numerous outlier SNPs showing strong associations with variation in altitude (1394 SNPs), average annual temperature (1859 SNPs) or both (1051 SNPs). Levels and patterns of genetic differentiation in these SNPs were consistent with the hypothesis that they have been subject to directional selection and reflect adaptation to altitudinal variation among the study sites. Genes with footprints of selection were significantly enriched in binding and metabolic processes. Several genes potentially related to high altitude adaptation were identified, although the identity and functional significance of most genomic targets of selection remain unknown. In general, the results provide genomic support for results of earlier common garden and low coverage genetic studies that have uncovered substantial adaptive differentiation along altitudinal and latitudinal gradients in amphibians.

    Cucumber mosaic virus (CMV) causing mosaic, leaf distortion and stunting of vanilla (Vanilla planifolia Andrews) in India was characterized on the basis of biological and coat protein (CP) nucleotide sequence properties. In mechanical inoculation tests, the virus was found to infect members of Chenopodiaceae, Cucurbitaceae, Fabaceae and Solanaceae. Nicotiana benthamiana was found to be a suitable host for the propagation of CMV. The virus was purified from inoculated N. benthamiana plants and negatively stained purified preparations contained isometric particles of about 28 nm in diameter. The molecular weight of the viral coat protein subunits was found to be 25.0 kDa. Polyclonal antiserum was produced in New Zealand white rabbit, immunoglobulin G (IgG) was purified and conjugated with alkaline phosphatase enzyme. Double antibody sandwich-enzyme linked immunosorbent assay (DAS-ELISA) method was standardized for the detection of CMV infection in vanilla plants. CP gene of the virus was amplified using reverse transcriptase-polymerase chain reaction (RT-PCR), cloned and sequenced. Sequenced region contained a single open reading frame of 657 nucleotides potentially coding for 218 amino acids. Sequence analyses with other CMV isolates revealed the greatest identity with black pepper isolate of CMV (99%) and the phylogram clearly showed that CMV infecting vanilla belongs to subgroup IB. This is the first report of occurrence of CMV on V. planifolia from India.

    2015-01-01

    We study the Andrews-Gordon-Bressoud (AGB) generalisations of the Rogers-Ramanujan q-series identities in the context of cylindric partitions. We recall the definition of r-cylindric partitions, and provide a simple proof of Borodin's product expression for their generating functions, that can be regarded as a limiting case of an unpublished proof by Krattenthaler. We also recall the relationships between the r-cylindric partition generating functions, the principal characters of affine sl_r algebras, the M^{r, r+d}_r minimal model characters of W_r algebras, and the r-string abaci generating functions, as well as the relationships between them, providing simple proofs for each. We then set r=2, and use 2-cylindric partitions to re-derive the AGB identities as follows. Firstly, we use Borodin's product expression for the generating functions of the 2-cylindric partitions with infinitely-long parts, to obtain the product sides of the AGB identities, times a factor (q; q)_{\\infty}^{-1}, which is the generating ...

    2015-10-01

    There are many areas of MD and HD vehicles that can be improved by new technologies and optimized control strategies. Component optimization and idle reduction need to be addressed, this is best done by a two part approach that includes selecting the best component technology, and/or architecture, and optimized controls that are vehicle focused. While this is a common focus in the light duty industry it has been gaining momentum in the MD and HD market as the market gets more competitive and the regulations become more stringent. When looking into systems optimization and idle reduction technologies, affected vehicle systems must first be considered, and if possible included in the new architecture to get the most benefit out of these new capabilities. Typically, when looking into idle reduction or component optimization for MD/HD, the vehicle s accessories become a prime candidate for electrification or hybridization. While this has already been studied on light duty vehicles (especially on hybrids and electric vehicles) it has not made any head way or market penetration in most MD and HD applications. If hybrids and electric MD and HD vehicles begin to break into the market this would be a necessary step into the ability to make those vehicles successful by allowing for independent, optimized operation separate from the engine.

    Full Text Available The long-standing friendship between Andrew Lang (1844-19121 and Henry RiderHaggard (1856-19252 is surely one of the most intriguing literary relationships ofthe Victorian era.3 Lang was a pre-eminent literary critic and his support forHaggard’s earliest popular romances, such as King Solomon’s mines (1885 andShe (1887, helped to establish them as leading models of the new genre ofimperial adventure fiction.4 Lang and Haggard co-authored The world’s desire(18905 and the ideas of Lang, who was also a brilliant Classics scholar, can beseen in many of Haggard’s works. There are some significant similarities betweenthe two men: both were approximate contemporaries who lived through the mostaggressive phase of British imperialism, both were highly successfully writers whoearned their living by their pens, both wrote prolifically and fluently on a wide range of subjects,6 both were largely self-educated, both were interested in thesupernatural, both had had unhappy experiences in love at first but later maintainedlong-lasting marriages, and both were men with powerful faculties of imagination.There are, of course, significant differences also: Lang was a gifted intellectualwho had won a fellowship at Oxford, a Homeric scholar, a poet with a gift forirony and humour, and one of the earliest exponents of the new science ofanthropological mythology; Haggard was less well educated and more seriousminded,he preferred action to ideas, was personally involved in the extension ofBritish rule in Southern Africa,7 and had a close experience of African tribal life.This article sets out to investigate the relationship between these two men, and toassess the extent to which Lang’s classical and anthropological thinking shaped thenarratives of Haggard, especially those set in his imperialistic fantasy of theAfrican continent.

  4. Construction, Startup and Operation of a New LLRW Disposal Facility in Andrews County, Texas - 12151

    International Nuclear Information System (INIS)

    During this last year, Waste Control Specialists LLC (WCS) completed construction and achieved start of operations of a new low level radioactive waste (LLRW) disposal facility in Andrews County Texas. Disposal operations are underway for commercial LLRW, and start up evolutions are in progress for disposal of Department of Energy (DOE) LLRW. The overall approach to construction and start up are presented as well as some of the more significant challenges and how they were addressed to achieve initial operations of the first new commercial low level radioactive waste disposal facility in more than 30 years. The WCS disposal facility consists of two LLRW disposal cells, one for Texas Compact waste, and a separate disposal cell for DOE waste. Both disposal cells have very robust and unique designs. The cells themselves are constructed entirely in very low permeability red bed clay. The cell liners include a 0.91 meter thick clay liner meeting unprecedented permeability limits, 0.3 meter thick reinforced concrete barriers, as well as the standard geo-synthetic liners. Actions taken to meet performance criteria and install these liners will be discussed. Consistent with this highly protective landfill design, WCS chose to install a zero discharge site water management system. The considerations behind the design and construction of this system will be presented. Other activities essential to successful start of LLRW disposal operations included process and procedure development and refinement, staffing and staff development, and training. Mock ups were built and used for important evolutions and functions. Consistent with the extensive regulation of LLRW operations, engagement with the Texas Commission on Environmental Quality (TCEQ) was continuous and highly interactive. This included daily activity conference calls, weekly coordination calls and numerous topical conference calls and meetings. TCEQ staff and consultants frequently observed specific construction

  5. Low-Frequency Response Following the Passage of Hurricane Andrew on the Texas-Louisiana Shelf

    2009-12-01

    During August 24th through 27th in 1992, Hurricane Andrew passed through the Gulf Of Mexico almost directly over several moorings on the easternmost Louisiana shelf portion of the Texas-Louisiana Shelf (LATEX) coastal ocean monitoring program. Examination of the current meter time-series showed the existence of fast moving, long shelf waves over the entire Texas-Louisiana shelf west of the storm passage for up to 12 days after direct forcing ceased. The LATEX program featured 31 moorings each with 3 current meters over the 10, 20, 50, and 200 meter isobaths in 5 cross sectional lines with additional coverage on the 200 meter isobath from the Louisiana-Mississippi River delta, to Corpus Christi, Texas. Additionally, several pressure records from LATEX and several NOAA historical coastal tide gauge data from Sabine Pass to Port Isabella, Texas were incorporated. Raw, 3-hour low pass filtered, and 40-hour low pass filtered versions of the current data were analyzed. The pressure data used were detided using a least squares fit, and the tidal records were detided using the NOAA predicted tides for that location. All data were analyzed using a wavelet analysis to determine the spectra over time. The analyzed data shows that the shelf response was largely dominated in the internal Kelvin wave mode. The wave propagated towards the west on the shelf at approximately 400 km/day. These results are contrasted and compared with wave modes predicted for coastal trapped wave solutions. The output of a coastal ocean model simulation using a forced wind field similar to the storm are also contrasted and compared with the observed data.

  13. Improved Collision Attack on Hash Function MD5

    Jie Liang; Xue-Jia Lai

    2007-01-01

    In this paper, we present a fast attack algorithm to find two-block collision of hash function MD5.The algorithm is based on the two-block collision differential path of MD5 that was presented by Wang et al.In the Conference EUROCRYPT 2005.We found that the derived conditions for the desired collision differential path were not sufficient to guarantee the path to hold and that some conditions could be modified to enlarge the collision set.By using technique of small range searching and omitting the computing steps to check the characteristics in the attack algorithm, we can speed up the attack of MD5 efficiently.Compared with the Advanced Message Modification technique presented by Wang et al.,the small range searching technique can correct 4 more conditions for the first iteration differential and 3 more conditions for the second iteration differential, thus improving the probability and the complexity to find collisions.The whole attack on the MD5 can be accomplished within 5 hours using a PC with Pentium4 1.70GHz CPU.

    Losses at injection depend on the beam quality in the longitudinal and transverse plane in the injectors. During the MD on the 30th of June to 1st of July, 2011, many parameters in the injectors were de-tuned on purpose to see the effect on injection losses and hence bring some understanding to recurring problems with injection quality during LHC filling. The effect of the 800 MHz in the SPS, radial steering, larger momentum spread at the SPS extraction and many other longitudinal parameters were studied during the MD. The MD showed however that the injection losses are dominated by far by the transverse size of the particle population. If the SPS scrapers are correctly positioned, injection losses are low even at the presence of quality issues in the longitudinal plane. To be able to inject brighter 50 ns beams or eventually 25 ns beams, injection losses with nominal emittances (3.5 m) must still be acceptable. This MD showed that nominal emittances can be injected with similar loss levels as the typical ...

  16. Developing improved MD codes for understanding processive cellulases

    International Nuclear Information System (INIS)

    The mechanism of action of cellulose-degrading enzymes is illuminated through a multidisciplinary collaboration that uses molecular dynamics (MD) simulations and expands the capabilities of MD codes to allow simulations of enzymes and substrates on petascale computational facilities. There is a class of glycoside hydrolase enzymes called cellulases that are thought to decrystallize and processively depolymerize cellulose using biochemical processes that are largely not understood. Understanding the mechanisms involved and improving the efficiency of this hydrolysis process through computational models and protein engineering presents a compelling grand challenge. A detailed understanding of cellulose structure, dynamics and enzyme function at the molecular level is required to direct protein engineers to the right modifications or to understand if natural thermodynamic or kinetic limits are in play. Much can be learned about processivity by conducting carefully designed molecular dynamics (MD) simulations of the binding and catalytic domains of cellulases with various substrate configurations, solvation models and thermodynamic protocols. Most of these numerical experiments, however, will require significant modification of existing code and algorithms in order to efficiently use current (terascale) and future (petascale) hardware to the degree of parallelism necessary to simulate a system of the size proposed here. This work will develop MD codes that can efficiently use terascale and petascale systems, not just for simple classical MD simulations, but also for more advanced methods, including umbrella sampling with complex restraints and reaction coordinates, transition path sampling, steered molecular dynamics, and quantum mechanical/molecular mechanical simulations of systems the size of cellulose degrading enzymes acting on cellulose

    Two MADS-box genes, MdMADS3 and MdMADS4, were isolated from the apple (Malus x domestica Borkh.) cultivar Fuji, and their spatial and temporal expression patterns were studied during morphological differentiation of the flower buds and the fruits. Both MdMADS3 and MdMADS4 showed high sequence similarities to FBP2 from petunia, TM5 from tomato, and AGL2, AGL4 from Arabidopsis. Although MdMADS3 was expressed in the inner three whorls of the floral primordium, its expression was hardly detectable in developing fruit. The second gene, MdMADS4, was ubiquitously expressed in the inflorescence meristem, floral meristem, all four floral organs, and fruit. Moreover, MdMADS4 expression was high in the vascular bundles assigned to the floral tube and the carpellary vascular bundles in fruit at early developmental stages. The MdMADS4 transcript also accumulated in embryos of the developing seeds. These results suggest that MdMADS3 and MdMADS4 are involved in different functions, and that MdMADS4 may function in the important events controlling flower and fruit development. PMID:10787044

    Hurricanes can be very different from each other. Here we examine the impacts that two hurricanes, Andrew and Wilma, had in terms of storm surge and sediment deposition on the southwest coast of Florida. Although Wilma was the weaker storm, it had the greater impact. Wilma had the higher storm surge over a larger area and deposited more sediment than did Andrew. This effect was most likely due to the size of Wilma's eye, which was four times larger than that of Andrew.

    2016-01-01

    MD210 aims for the creation of longitudinally hollow bunches in the CERN PS Booster. The first three sessions have been carried out using the radial loop feedback system in order to drive the beam on a dipolar parametric resonance (instead of the phase loop). It has been found that the damping by the phase loop inhibits the excitation of the resonance to a major extent. The hollow distributions generated under these circumstances fail to reach a satisfying bunching factor. Nonetheless, proving the principally successful application of this technique to the PS Booster promises good results once the phase loop system supports trim functions. The approach, actions and detailed results of the first three MD sessions are presented in this paper.

    The Beam Transfer Function (BTF) measurements have been previously tested in the LHC during MD block 1 and 2. Different machine configurations (i.e. energy, beam intensity, emittance etc...) have been tested to determine a safe set-up (excitation amplitude) of the system to be completely transparent to the beam (no emittance blow-up neither losses). The aim of this experiment in MD block 3 was to characterize the Stability Diagram (SD) in the presence of diffusion mechanisms induced by excited resonances due to beam-beam long range and Landau octupole interplay. During the experiment, BTF measurements have been acquired at flat top for different settings of Landau octupole current, different chromaticity values and transverse feedback gains. In this note the description of the experiment is presented together with some preliminary results.

    The sufficient conditions for keeping desired differential path of MD5 was discussed. By analyzing the expanding of subtraction difference, differential characters of Boolean functions, and the differential characters of shift rotation, the sufficient conditions for keeping desired differential path could be obtained. From the differential characters of shift rotation, the lacked sufficient conditions were found. Then an algorithm that reduces the number of trials for finding collisions were presented. By restricting search space, search operation can be reduced tc 234 for the first block and 230 for the second block. The whole attack on the MD5 can be accomplished within 2C hours using a PC with 1.6 G CPU.

    Measurements made since the beginning of run II at 6.5 TeV have shown that there is a large discrepancy in the instability thresholds between single bunches and trains of 72 bunches with 25ns spacing, whereas the same result is expect for pure impedance-induced instabilities. One possible explanation is that the presence of electron cloud is affecting the beam stability. This MD will attempt to determine if electron cloud is the dominant mechanism affecting beam stability.

    Maitake mushroom (Grifola frondosa) MD-fraction containing beta-1,6 glucan with beta-1,3 branched chains has previously exhibited strong anticancer activity by increasing immune-competent cell activity.1,2 In this non-random case series, a combination of MD-fraction and whole maitake powder was investigated to determine its effectiveness for 22- to 57-year-old cancer patients in stages II-IV. Cancer regression or significant symptom improvement was observed in 58.3 percent of liver cancer patients, 68.8 percent of breast cancer patients, and 62.5 percent of lung cancer patients. The trial found a less than 10-20 percent improvement for leukemia, stomach cancer, and brain cancer patients. Furthermore, when maitake was taken in addition to chemotherapy, immune-competent cell activities were enhanced 1.2-1.4 times, compared with chemotherapy alone. Animal studies have supported the use of maitake MD-fraction for cancer. PMID:12126464

  14. Review of 40-year MD theses in Medical Oncology

    International Nuclear Information System (INIS)

    Background and objective: It is almost 40 years since the foundation of the Medical Oncology (MO) Department. We aimed to appraise the clinical research to fulfill the Medical Doctorate (MD) degree in MO at the National Cancer Institute, Cairo University (NCI, CU). Methods: This review included 62 MD theses containing 66 studies. They were reviewed regarding aims, type of study, clinical trial phase, design and methodology, statistical tests, results, limitations, consent and IRB approval. Theses were grouped into 3 periods: 1970-1989, 1990-1999 and 2000- 2008. Results: Almost 76% of the studies were interventional and 24% were observational. Informed consent and Institutional Review Board approval were mentioned in 18 and 2 studies, respectively. While all studies mentioned the aims, none, clearly mentioned the research question. Outcomes were mainly efficacy followed by safety. Study design was inadequately considered, especially in 70’s–80’s period (p = 0.038). Median sample size and study duration were almost stable through the three periods (p = 0.441, 0.354, respectively). Most of the studies used both descriptive and analytical statistical methods. In a descending order, researched cancers were lymphoma, breast, leukemia, liver, urinary bladder, lung and colorectal. The commonest stages researched were IV and III. The number of studies focused on assessing biomarkers, biomarkers plus drugs/procedures, drugs and procedures are 20, 20, 16 and 6, respectively. Conclusion: With time, research within MD theses in MO increased quantitatively and qualitatively. Improvements were noticeable in documentation of study design.

  15. Structure and Properties of HELICAL CARBON NANOTUBES through MD Simulations

    Science.gov (United States)

    Dahiya, Akshay; Verma, Deepti; Gupta, Shakti S.

    Helical Carbon Nanotubes (HCNTs) are coiled 3-valent carbon networks which represent pure carbon helix. Here we study the geometries of two classes: hexagonal helix containing purely polyhex networks and the second class with 5-and 7-membered rings besides hexagons. We followed a model of hexagonal, single wall HCNTs, and determined their relaxed configuration using MD simulations based on Tersoff potential. A race-track like structure is observed in the cross-section of HCNTs upon minimization. For generating class two helix, the adjacency matrix eigenvector's (AME) method is applied which utilizes 3-coordinated tiling of the plane by 5-,6-,and 7-membered ring for the construction of helical structures. The application of the AME method to torusenes is crucial for class two helix generation as it is based on an appropriate choice of bi-lobial eigenvectors triplet which can be selected on the basis of their nodal properties as verified here. After 3-D transformations the final structure was obtained with the help of MM3-potential based MD simulations on Tinker commercial code. The spring constants of HCNTs are computed through MD simulations.

The US Department of Energy (DOE) has funded Purdue University School of Nuclear Engineering during the period of five academic years covered in this report starting in the academic year 1996-97 and ending in the academic year 2000-2001. The total amount of funding for the grant received from DOE is $416K. In the 1990's, Nuclear Engineering Education in the US experienced a significant slow down. Student enrollment, research support, number of degrees at all levels (BS, MS, and PhD), number of accredited programs, University Research and Training Reactors, all went through a decline to alarmingly low levels. Several departments closed down, while some were amalgamated with other academic units (Mechanical Engineering, Chemical Engineering, etc). The School of Nuclear Engineering at Purdue University faced a major challenge when in the mid 90's our total undergraduate enrollment for the Sophomore, Junior and Senior Years dropped in the low 30's. The DOE Matching Grant program greatly strengthened Purdue's commitment to the Nuclear Engineering discipline and has helped to dramatically improve our undergraduate and graduate enrollment, attract new faculty and raise the School of Nuclear Engineering status within the University and in the National scene (our undergraduate enrollment has actually tripled and stands at an all time high of over 90 students; total enrollment currently exceeds 110 students).

    International Nuclear Information System (INIS)

    The Commission of the European Community has instituted a host of energy grant schemes of several years duration worth more than 2 billion ECU altogether. It thereby aims at research and development, demonstration and transfer to market of energy technologies, energy conservation, and energy-use efficiency, as well as at the harnessing of renewable energy sources. Besides, there are national German programs worth more than 5 billion DM. EUREKA with its 19 member states is a technology initiative comprising the whole of Europe that equally initiates and funds energy projects for a volume of, currently, about 1.1 billion DM. This guide informs undertakings as well as scientists and researchers on all programs in condensed form. Transparency and topicality, the availability of contact persons and ease of contacting are keys to successful participation. The book is intended as an aid especially for small and medium-sized enterprises as well as for enterprises in the new federal states. (orig.)

  7. A Secure Hash Function MD-192 With Modified Message Expansion

    CERN Document Server

    Tiwari, Harshvardhan

    2010-01-01

    Cryptographic hash functions play a central role in cryptography. Hash functions were introduced in cryptology to provide message integrity and authentication. MD5, SHA1 and RIPEMD are among the most commonly used message digest algorithm. Recently proposed attacks on well known and widely used hash functions motivate a design of new stronger hash function. In this paper a new approach is presented that produces 192 bit message digest and uses a modified message expansion mechanism which generates more bit difference in each working variable to make the algorithm more secure. This hash function is collision resistant and assures a good compression and preimage resistance.

    2007-12-01

    Plant phenology data has been collected at three sites on the H.J. Andrews Experimental Forest, Oregon since the late 1970's. The sites were visited once every three weeks year-round. Current efforts to clean and archive this data are on-going. Here we present on a 20 year data set from 1987 to 2007. The three sites are located at Watersheds (WS) 10, 8, and 7/6, at an elevation of 466 m, 993 m, and 905/950 m respectively. Forests were old growth (WS 8) and regenerating clearcuts (WS 6, 10), or shelterwood clearcut with overstory removed in 1984 (WS 7) dominated by Douglas-fir, western hemlock, true firs, and western redcedar. One tree (Douglas-fir), two evergreen shrubs, three deciduous shrubs, and four herbs were followed for vegetative and flowering phenology, including bud swell, bud bread, leaf expansion, leaf color change, leaf fall, flower bud swell, blooming, petal loss, fruit formation, and seed dispersal. Weather stations are located at each site and tied into a network of stations in this LTER site. Physical factors such as snow depth, snow coverage, freeze-thaw activity, as well as lichen condition were also noted. We are asking two key questions regarding plant phenology patterns. 1. Has the growing season lengthened in the mountainous watershed of the HJ Andrews, and is this similar for a low elevation site (WS 10) versus a mid elevation site (WS 8, 7/6)? 2. Do snow-pack dynamics influence plant phenology more so than temperature (degree days)?

    2010-11-01

    Professor Frantisek Por MD and Professor Robert Klopstock MD were contemporaries, both born in 1899, one in Zvolen, the other in Dombovar, at the time of Austro-Hungarian Monarchy. Prof. Por attended the Faculty of Medicine in Budapest from 1918 to 1920, and Prof. Klopstock studied at the same place between 1917 and 1919. From 1920 until graduation on 6th February 1926, Prof. Por continued his studies at the German Faculty of Medicine, Charles University in Prague. Prof. Klopstock had to interrupt his studies in Budapest due to pulmonary tuberculosis; he received treatment at Tatranske Matliare where he befriended Franz Kafka. Later, upon Kafka's encouragement, he changed institutions and continued his studies at the German Faculty of Medicine, Charles University in Prague, where he graduated the first great go. It is very likely that, during their studies in Budapest and Prague, both professors met repeatedly, even though their life paths later separated. Following his graduation, Prof. Por practiced as an internist in Prague, later in Slovakia, and from 1945 in Kosice. In 1961, he was awarded the title of university professor of internal medicine at the Faculty of Medicine, Pavol Jozef Safarik University in Kosice, where he practiced until his death in 1980. Prof. Klopstock continued his studies in Kiel and Berlin. After his graduation in 1933, he practiced in Berlin as a surgeon and in 1938 left for USA. In 1962, he was awarded the title of university professor of pulmonary surgery in NewYork, where he died in 1972. PMID:21250499

  5. Fred Loe, MD, and the history of trachoma.

    Science.gov (United States)

    Feibel, Robert M

    2011-04-01

    Trachoma has been one of the most blinding diseases in the history of ophthalmology. From its initial description in antiquity until the late 1930s, no specific treatment or effective cure had been known, and the only expedient had been to destroy the diseased tissue containing the infectious agent, rendering the disease inactive. Virtually all medical, mechanical, and surgical treatments were unsatisfactory, with cure rates of approximately 20%. Therapy for trachoma had barely advanced from the measures used by the ancient Egyptian, Greek, and Roman physicians. All prior therapies became obsolete in 1938 when Fred Loe, MD, working on an American Indian reservation, introduced sulfanilamide as a treatment of trachoma, achieving a 90% cure rate. One of the most unusual aspects of Loe's career was that he had no formal training in ophthalmology and was completely self-taught as an ophthalmologist. PMID:21482877

  6. A workshop on leadership for MD/PhD students

    Directory of Open Access Journals (Sweden)

    2011-08-01

    Full Text Available Success in academic medicine requires scientific and clinical aptitude and the ability to lead a team effectively. Although combined MD/PhD training programs invest considerably in the former, they often do not provide structured educational opportunities in leadership, especially as applied to investigative medicine. To fill a critical knowledge gap in physician-scientist training, the Vanderbilt Medical Scientist Training Program (MSTP developed a biennial two-day workshop in investigative leadership. MSTP students worked in partnership with content experts to develop a case-based curriculum and deliver the material. In its initial three offerings in 2006, 2008, and 2010, the workshop was judged by MSTP student attendees to be highly effective. The Vanderbilt MSTP Leadership Workshop offers a blueprint for collaborative student-faculty interactions in curriculum design and a new educational modality for physician-scientist training.

  7. Thermal Sensitivity of MD Hematite: Implication for Magnetic Anomalies

    Science.gov (United States)

    Kletetschka, Gunther; Wasilewski, Peter J.; Taylor, Patrick T.

    1999-01-01

    Magnetic remanence of crustal rocks can reside in three common rock-forming magnetic minerals: magnetite, pyrrhotite, and hematite. Thermoremanent magnetization (TRM) of magnetite and pyrrhotite is carried mostly by single domain (SD) grains. The TRM of hematite grains, however, is carried mostly by multidomain (NM) grains. This characteristic is illustrated by TRM acquisition curves for hematite of variable grainsizes. The transition between truly NM behavior and tendency towards SD behavior his been established between hematite grainsizes of 0. 1 and 0.05 mm. Coarse grainsize of lower crustal rocks and the large sensitivity of MD hematite grains to acquire TRM indicates that hematite could be a significant contributor to long-wavelength magnetic anomalies.

  11. Plasticity and Failure in Nanocrystalline BCC Metals via MD Simulation

    Energy Technology Data Exchange (ETDEWEB)

    Rudd, R E

    2010-02-12

    Advances in the ability to generate extremely high pressures in dynamic experiments such as at the National Ignition Facility has motivated the need for special materials optimized for those conditions as well as ways to probe the response of these materials as they are deformed. We need to develop a much deeper understanding of the behavior of materials subjected to high pressure, especially the effect of rate at the extremely high rates encountered in those experiments. Here we use large-scale molecular dynamics (MD) simulations of the high-rate deformation of nanocrystalline tantalum at pressures less than 100 GPa to investigate the processes associated with plastic deformation for strains up to 100%. We focus on 3D polycrystalline systems with typical grain sizes of 10-20 nm. We also study a rapidly quenched liquid (amorphous solid) tantalum. We apply a constant volume (isochoric), constant temperature (isothermal) shear deformation over a range of strain rates, and compute the resulting stress-strain curves to large strains for both uniaxial and biaxial compression. We study the rate dependence and identify plastic deformation mechanisms. The identification of the mechanisms is facilitated through a novel technique that computes the local grain orientation, returning it as a quaternion for each atom. This analysis technique is robust and fast, and has been used to compute the orientations on the fly during our parallel MD simulations on supercomputers. We find both dislocation and twinning processes are important, and they interact in the weak strain hardening in these extremely fine-grained microstructures. We also present some results on void growth in nanocrystalline BCC metals under tension.

  15. MD-2 determinants of nickel and cobalt-mediated activation of human TLR4.

    Directory of Open Access Journals (Sweden)

    Alja Oblak

    Full Text Available Recent findings unexpectedly revealed that human TLR4 can be directly activated by nickel ions. This activation is due to the coordination of nickel by a cluster of histidine residues on the ectodomain of human TLR4, which is absent in most other species. We aimed to elucidate the role of MD-2 in the molecular mechanism of TLR4/MD-2 activation by nickel, as nickel binding site on TLR4 is remote from MD-2, which directly binds the endotoxin as the main pathological activator of TLR4. We identified MD-2 and TLR4 mutants which abolished TLR4/MD-2 receptor activation by endotoxin but could nevertheless be significantly activated by nickel, which acts in synergy with LPS. Human TLR4/MD-2 was also activated by cobalt ions, while copper and cadmium were toxic in the tested concentration range. Activation of TLR4 by cobalt required MD-2 and was abolished by human TLR4 mutations of histidine residues at positions 456 and 458. We demonstrated that activation of TLR4 by nickel and cobalt ions can trigger both the MyD88-dependent and the -independent pathway. Based on our results we propose that predominantly hydrophobic interactions between MD-2 and TLR4 contribute to the stabilization of the TLR4/MD-2/metal ion complex in a conformation that enables activation.

  20. Apocalyptic Kingship, Harmony and Political Expediency: the Challenges and Paradoxes of Andrew Marvell’s “First Anniversary”

    Directory of Open Access Journals (Sweden)

    Jajtner Tomáš

    2015-07-01

    Full Text Available The following paper deals with the interpretation of one of the major “Cromwellian” poems of Andrew Marvell (1621-1678, “The First Anniversary of the Government under His Highness the Lord Protector”, 1655. The poem is first set in the context of Marvell’s poetry and his public career in the period between 1637 and 1660. The article then identifies and analyses three main themes of “The First Anniversary”: the notion of a new aeon starting with Cromwell’s rule and the apocalyptical imagery related to his Protectorate, the concept of his power and authority between liberty and tyranny, and the relation between the harmony established by Cromwell and classical Pythagorean harmonious lore. The author argues that the imagery Marvell uses to describe the nature of the regime (especially the concept of Cromwell’s “no-kingship” shows a deeply paradoxical structure, which uncovers the frailty and insecurity of Cromwell’s dictatorship as well as the circular logic of its justification. In that sense, the poem can be read as a vivid manifestation of the dilemmas and tensions of this period.

    通过研究不同的差分分析对MD5算法的攻击后发现,差分分析攻击之所以可以成功,是因为在MD5算法中改变了明文中一些特定位,而这些特定位的改变在许多轮中最多只影响链接变量的几个位,并且这些小的差分能在随后的多轮操作中得到纠正,从而产生了碰撞.这就说明原MD5算法的雪崩效应不能阻止差分分析的攻击,而为了提高MD5算法的安全性,必须提高其雪崩效应的敏感性.分析结果表明,用动态明文变化函数对MD5算法进行修改,能使其产生更敏感的雪崩效应,以此来有效防止差分分析攻击,提高MD5算法的安全性.

    2010-09-01

    Full Text Available Bacterial aerosol have been observed and studied in the ambient environment since the mid nineteenth century. These studies have sought to provide a better understanding of the diversity, variability and factors that control the biological aerosol population. In this study, we show comparisons between diversity of culturable bacteria and fungi, using culture and clinical biochemical tests, and 16S rRNA diversity using Affymetrix PhyloChips. Comparing the culturable fraction and surveying the total 16S rRNA of each sample provides a comprehensive look at the bacterial population studied and allows comparison with previous studies. Thirty-six hour back-trajectories of the air parcels sampled, over the two day period beginning 4 November 2008, provide information on the sources of aerosol sampled on the campus of Johns Hopkins University Applied Physics Laboratory in Laurel, MD. This study indicates that back-trajectory modeling of air parcels may provide insights into the observed diversity of biological aerosol.

  17. The MD simulation of thermal properties of plutonium dioxide

    International Nuclear Information System (INIS)

    The thermodynamic properties of PuO2 have been investigated between 300 and 3000 K by molecular dynamics (MD) simulation with empirical interaction potential. The properties include melting point, lattice parameter variation, enthalpy and heat capacity. The melting point of two-phase simulation (TPS) is in agreement with the experimental value, and it gives a much lower value than one-phase simulation (OPS). The lattice parameter and heat capacity at high temperatures are expressed as a(T)=5.38178+4.38×10-5T+6.5525×10-9T2+0.9362×10-12T3 and CP(KJ⋅mol-1⋅K-1)=18648.8e474.5/T/(T2(e474.5/T-1)2)+9.337×10-6T, respectively. True linear thermal expansion coefficient (TLTEC) α is about 8.89×10-6 K-1 at 300 K. Our simulation results are in good agreement with experimental and other theoretical data.

    2000-09-26

    Before the discoveries of John Call Dalton, Jr., MD (1824-1889), innervation of laryngeal muscles, long-term effects of cerebellar lesions, and consequences of raised intracranial pressure were poorly understood. Dalton discovered that the posterior cricoarytenoid muscles adducted the vocal cords during inspiration. He confirmed Flourens' observations that acute ablation of the cerebellum of pigeons caused loss of coordination. Dalton observed that properly cared for pigeons gradually recovered "coordinating power." Dalton observed that prolonged raised intracranial pressure caused tachycardia and then fatal bradycardia in dogs. Before Dalton published his photographic atlas of the human brain, neuroanatomy atlases were sketched by Europeans and imported into the United States. Dalton's atlas of the human brain contained precise photographs of vertical and horizontal sections that equal modern works. Before Dalton introduced live demonstrations of animals, physiology was taught by recitation of texts only. Dalton was the first American-born professor to teach physiology employing demonstrations of live animals operated on under ether anesthesia. He wrote an essay advocating experimentation on animals as the proper method of acquiring knowledge of function and that humane animal experimentation would ultimately improve the health of man and animals. His eloquent advocacy for humane experimental physiology quelled attacks by contemporaneous antivivisectionists. Dalton was America's first experimental neurophysiologist. PMID:10994009

    This work assessed the mechanism underlying the antisecretory gastric acid effect of Plectranthus barbatus Andrews (Lamiaceae) and active constituents. Popularly known as "false-boldo", this plant is used in Brazilian folk medicine to treat gastrointestinal and hepatic ailments. The plant aqueous extract (AE) and isolated compounds were assayed in vivo in pylorus-ligated mice, and in vitro on acid secretion measured as [(14)C]-aminopyrine ([(14)C]-AP) accumulation in rabbit gastric glands and gastric H(+),K(+)-ATPase preparations. Injected into the duodenal lumen, the AE of the plant leaves (0.5 and 1.0 g/kg) decreased the volume (62 and 76%) and total acidity (23 and 50%) of gastric acid secretion in pylorus-ligated mice. Bioguided purification of the AE yielded an active fraction (IC(50)=24 microg/ml) that inhibited acid secretion in rabbit gastric glands with a potency 10 to 18 times greater than that of the originating extract, on both the basal and stimulated acid secretion by histamine (His) (1 microM) or bethanechol (100 microM). At the same concentrations the gastric H(+),K(+)-ATPase activity was also inhibited. The active constituent was chemically identified as the abietanoid dienedione plectrinone A which reduced the H(+),K(+)-ATPase activity with IC(50)=171 microM. The results indicate that inhibition of the gastric proton pump by this diterpenoid may account for the antisecretory acid effect and reputed anti ulcer activity of Plectranthus barbatus.

  20. Hurricane Andrew causes major oil spill at Florida Power ampersand Light Company's Turkey Point Power Plant, Homestead, Florida

    International Nuclear Information System (INIS)

    On August 24, 1992, Hurricane Andrew slammed into South Florida with wind gusts in excess of 160 mph. At 4:00 a.m. that day, the eye of this category four storm passed over Florida Power ampersand Light Company's Turkey Point power plant, south of Miami. Although the plant's two nuclear units escaped any significant damage, the storm caused extensive destruction to buildings and transmission facilities, and damaged two 400 foot tall emission stacks associated with the site's two fossil fuel generating units. In addition, a 90,000 to 110,000 gallon spill of No. 6 fuel oil resulted when a piece of wind-blown debris punctured the steel of the unit One 12,000 barrel fuel oil metering tank approximately 30 feet up from the tank bottom. Despite the presence of a secondary containment structure around the tank, the intense wind blew oil throughout the plant site. The damage to the metering tank apparently occurred during the first half hour of the hurricane. As the tank's oil level fell due to the puncture, transfer pumps from the bulk oil storage tanks received a low level alarm which automatically began transferring oil to the damaged metering tank. To prevent the further discharge of oil, plant personnel entered the power block and secured the pumps during the passage of the hurricane eye. Immediately following the storm, facility personnel deployed booms across the barge canal and the Units 1 and 2 intake canal to contain the oil which had entered the water. The response strategy and implementation is described in detail. The remediation costs were approximately $14/gallon spilled, including 54,000 gallons recovered for electricity generation

    If MD5 algorithm is directly used to encrypt sensitive data in database, the data is unable to be deerypted by this algorithm itself, even legitimate users query or update some data for the purpose of restoring data. The database becomes more redundant because secret keys need to be saved for reversible encryption algorithms. This paper proposes a reversible non-redundant encryption algorithm based on MD5 algorithm, which can be ~ to used encrypt and decrypt sensitive data in the database regardless of saving secret keys.%直接采用MD5算法对数据库中的敏感数据加密时,合法用户进行查询、更新等操作需要还原数据,MD5算法无法解密数据.可逆的加密算法都需要保存密钥,数据库增加了数据的冗余.本文提出一种基于MD5算法的可逆无冗余算法,实现对数据库中敏感数据进行加密、解密,而且不需要保存密钥.

    Full Text Available Nutrient deficiencies restrict apple (Malus sp. tree growth and productivity in Northwest China. The process of autophagy, a conserved degradation pathway in eukaryotic cells, has important roles in nutrient-recycling and helps improve plant performance during periods of nutrient-starvation. Little is known about the functioning of autophagy-related genes (ATGs in apple. In this study, one of the ATG8 gene family members MdATG8i was isolated from M. domestica. MdATG8i has conserved putative tubulin binding sites and ATG7 interaction domains. A 1865-bp promoter region cloned from apple genome DNA was predicated to have cis-regulatory elements responsive to light, environmental stresses and hormones. MdATG8i transcriptions were induced in response to leaf senescence, nitrogen depletion, and oxidative stress. At cellular level, MdATG8i protein was expressed in the nucleus and cytoplasm of onion epidermal cells. Yeast two-hybrid tests showed that MdATG8i could interact with MdATG7a and MdATG7b. In Arabidopsis, its heterologous expression was associated with enhanced vegetative growth, leaf senescence, and tolerance to nitrogen- and carbon-starvation. MdATG8i-overexpressing ‘Orin’ apple callus lines also displayed improved tolerance to nutrient-limited conditions. Our results demonstrate that MdATG8i protein could function in autophagy in a conserved way, as a positive regulator in the response to nutrient-starvation.

    This report summarizes the progress on the interatomic potential development of triuranium-disilicide (U3Si2) for molecular dynamics (MD) simulations. The development is based on the Tersoff type potentials for single element U and Si. The Si potential is taken from the literature and a Tersoff type U potential is developed in this project. With the primary focus on the U3Si2 phase, some other U-Si systems such as U3Si are also included as a test of the transferability of the potentials for binary U-Si phases. Based on the potentials for unary U and Si, two sets of parameters for the binary U-Si system are developed using the Tersoff mixing rules and the cross-term fitting, respectively. The cross-term potential is found to give better results on the enthalpy of formation, lattice constants and elastic constants than those produced by the Tersoff mixing potential, with the reference data taken from either experiments or density functional theory (DFT) calculations. In particular, the results on the formation enthalpy and lattice constants for the U3Si2 phase and lattice constants for the high temperature U3Si (h-U3Si) phase generated by the cross-term potential agree well with experimental data. Reasonable agreements are also reached on the elastic constants of U3Si2, on the formation enthalpy for the low temperature U3Si (m-U3Si) and h-U3Si phases, and on the lattice constants of m-U3Si phase. All these phases are predicted to be mechanically stable. The unary U potential is tested for three metallic U phases (α, β, γ). The potential is found capable to predict the cohesive energies well against experimental data for all three phases. It matches reasonably with previous experiments on the lattice constants and elastic constants of αU.

  14. A Mathematic Model That Describes Modes of MdSGHV Transmission within House Fly Populations

    2013-11-01

    Full Text Available In this paper it is proposed that one potential component by which the Musca domestica salivary gland hypertrophy virus (MdSGHV infects individual flies is through cuticular damage. Breaks in the cuticle allow entry of the virus into the hemocoel causing the infection. Male flies typically have a higher rate of infection and a higher rate of cuticular damage than females. A model for the transmission of MdSGHV was formulated assuming several potential and recognized means of transmission. The model yields results that are in agreement with field data that measured the infection rate in house flies on dairy farms in Florida. The results from this model indicate that MdSGHV will be maintained at a stable rate within house fly populations and support the future use of MdSGHV as a birth control agent in house fly management.

However, due to that the National Center of Metrology of Mexico delegates its functions in the dosimetry and activity area for the field of the ionizing radiations to the ININ: one of the requirements so that the ININ has been designated as -Declared Institute- before the International Office of Weights and Measurements, it is to demonstrate before the Inter-American System of Metrology that the quality system of the SLDC fulfills the standard ISO/IEC 17025: 2005, satisfied this requirement the Inter-American System of Metrology in their meeting of evaluation of quality systems, Ottawa (2007) grants a certification document to the SLDC that guarantees their capacities of calibration measurements for dosimetry services. Concretely, inside the standard activities ISO 9000 with respect to the point 8 on measurement, analysis and improvement the Management of Quality Assurance of ININ carries out at year two interns auditing and every month is given continuation to the non conformities detected in the procedures that support the services of the SLDC for dosimetry with purposes of radiological protection and clinical dosimetry.

    The strength of the Exploration Systems Mission Directorate ESMD Faculty Project lies in its ability to meet National Aeronautics Space Administration NASA's Strategic Educational Outcome 1 by developing a sustainable and long-term integration of student involvement at academic institutions with all NASA Centers. This outcome is achieved by a three-fold approach: 1) by collecting Senior Design projects pertaining to Constellation work performed at each of the ten NASA Centers, 2) by engaging students at Minority Serving Institutions in the art of systems engineering and systems design of technologies required for space exploration, and 3) by identifying potential internships at each Center relative to exploration that provide students who are supported by their institutional Space Grant to engage in on-going mission-level and explorative systems designs. The objectives of the ESMD Faculty Project are to: 1. Aid the Centers (both Education Offices and associated technical organizations) in providing relevant opportunities for the ESMD Space Grant Program to support student and faculty in Senior Design projects 2. Enable better matches between the ESMD work required and what the Space Grant Consortia can do to effectively contribute to NASA programs 3. Provide the Space Grant Consortia an opportunity to strengthen relations with the NASA Centers 4. Develop better collective understanding of the U.S. Space Exploration Policy by the Center, Space Grant, faculty, Education Office, and students 5. Enable Space Grant institution faculty to better prepare their students to meet current and future NASA needs 6. Enable the Center Education Offices to strengthen their ties to their technical organizations and Space Grant Consortia 7. Aid KSC in gaining a greater and more detailed understanding of each of the Center activities Senior Design projects are intended to stimulate undergraduate students on current NASA activities related to lunar, Mars, and other planetary missions

    Probabilistic models are formulated for the credit granting policy of a firm. First, a single-period analysis is presented for the credit-granting problem. Then a multi-period analysis for the same problem is presented, showing that the single-period analysis ignores important future benefits. The multi-period analysis contains a Bayesian approach to revisions of the probability of collection as collection experience is gained. The performance index, which has to be maximized with respect to the decision on how much credit to offer to credit applicants of different risk categories, contains some information of the future observations through the statistics of the observations given the present information. Dynamic programming is used to take into account the future effects of presents actions. A specific algorithm is derived which seems to be appropriate in terms of computational feasibility for this class of problems.

  10. Parallel cascade selection molecular dynamics (PaCS-MD) to generate conformational transition pathway

    Science.gov (United States)

    Harada, Ryuhei; Kitao, Akio

    2013-07-01

    Parallel Cascade Selection Molecular Dynamics (PaCS-MD) is proposed as a molecular simulation method to generate conformational transition pathway under the condition that a set of "reactant" and "product" structures is known a priori. In PaCS-MD, the cycle of short multiple independent molecular dynamics simulations and selection of the structures close to the product structure for the next cycle are repeated until the simulated structures move sufficiently close to the product. Folding of 10-residue mini-protein chignolin from the extended to native structures and open-close conformational transition of T4 lysozyme were investigated by PaCS-MD. In both cases, tens of cycles of 100-ps MD were sufficient to reach the product structures, indicating the efficient generation of conformational transition pathway in PaCS-MD with a series of conventional MD without additional external biases. Using the snapshots along the pathway as the initial coordinates, free energy landscapes were calculated by the combination with multiple independent umbrella samplings to statistically elucidate the conformational transition pathways.

  18. Evaluation of hydroacid complex in the forward osmosis–membrane distillation (FO–MD) system for desalination

    KAUST Repository

    Wang, Peng

    2015-11-01

    The incorporation of membrane distillation (MD) into forward osmosis (FO) provides process sustainability to regenerate the draw solution and to produce clean water simultaneously. However, the reverse salt flux is the major hurdle in the FO-MD system because it not only reduces the effective osmotic driving force across the membrane but also increases the replenishment cost and scaling issue. For the first time, a hydroacid complex with abundant hydrophilic groups and ionic species is evaluated as the draw solutes in the hybrid FO-MD system consisting of multi-bore PVDF MD membranes for seawater/brackish desalination. In order to evaluate the practicality of the hydroacid complex in the FO-MD system, FO and MD experiments were conducted at elevated temperatures and concentrations. The hydroacid complex has displayed desired properties such as high solubility, low viscosity, excellent thermal stability and minimal reverse salt flux suitable for FO and MD operations. FO-MD desalination process was demonstrated with a highest seawater desalination flux of 6/32 LMH (FO/MD). This study may open up the prospective of employing the hydroacid complex as the draw solute in FO-MD hybrid systems for seawater /brackish desalination. © 2015 Elsevier B.V.

    We present an efficient and highly accurate GP-GPU implementation of our community code, PuReMD, for reactive molecular dynamics simulations using the ReaxFF force field. PuReMD and its incorporation into LAMMPS (Reax/C) is used by a large number of research groups worldwide for simulating diverse systems ranging from biomembranes to explosives (RDX) at atomistic level of detail. The sub-femtosecond time-steps associated with ReaxFF strongly motivate significant improvements to per-timestep simulation time through effective use of GPUs. This paper presents, in detail, the design and implementation of PuReMD-GPU, which enables ReaxFF simulations on GPUs, as well as various performance optimization techniques we developed to obtain high performance on state-of-the-art hardware. Comprehensive experiments on model systems (bulk water and amorphous silica) are presented to quantify the performance improvements achieved by PuReMD-GPU and to verify its accuracy. In particular, our experiments show up to 16× improvement in runtime compared to our highly optimized CPU-only single-core ReaxFF implementation. PuReMD-GPU is a unique production code, and is currently available on request from the authors.

    The behaviour of sheared colloidal suspensions with full hydrodynamic interactions (HIs) is numerically studied. To this end, we use the hybrid stochastic rotation dynamics-molecular dynamics (SRD-MD) method. The shear viscosity of colloidal suspensions is computed for different volume fractions, both for dilute and concentrated cases. We verify that HIs help in the collisions and the streaming of colloidal particles, thereby increasing the overall shear viscosity of the suspension. Our results show a good agreement with known experimental, theoretical, and numerical studies. This work demonstrates the ability of SRD-MD to successfully simulate transport coefficients that require correct modelling of HIs.

    The Wheeling Disposal Service Company, Inc., (Wheeling Disposal) site is a closed municipal and industrial waste landfill, approximately 1 mile southeast of Amazonia, Andrew County, Missouri. On-site shallow groundwater is contaminated with Volatile Organic Compounds (VOCs) (methylene chloride, carbon tetrachloride, trichloroethylene) and metals; however, no one is using that water for potable purposes at present. Isolated farm houses are situated in the vicinity of the site, but the houses that would most likely be affected are connected to the public water system. From the information reviewed, DOH concludes that the Wheeling Disposal site currently poses no apparent public health hazard. No exposures are known to be occurring at this time. Potential exposure pathways have been identified, but remedial actions eliminated them.

    An engraving displaying A General View of the Absorbent System was used as one of many plates illustrating the Lymphatics section of Andrew Fyfe's Compendium of the Anatomy of the Human Body published in 1800. It is a scaled-down version of a life-size engraving displayed in the museum of the Department of Anatomy at the University of Edinburgh, and is based on a cadaver specially dissected and injected with mercury in 1788 by Alexander Monro secundus, probably with the assistance of Fyfe, who was his 'dissector'. Only recently has the relationship between these two engravings been established, and the Figure Legend in Fyfe's Compendium now provides the missing key to the features illustrated in the life-size engraving. The source and very variable quality of some of Fyfe's other plates, both in the Lymphatics section and elsewhere in the book, are discussed. PMID:9890727

An answer is attempted by, firstly, sketching the liturgical landscape as well as national and international liturgical-scientific developments in our day and, secondly, providing a liturgical-aesthetical exploration and positioning Die erediens as fees within these developments and exploration.

    MeOH extract from the leaves of Plectranthus barbatus Andrews (Lamiaceae), showed in vitro anti-trypanosomal activity. The bioassay-guided fractionation resulted in the isolation of a gallic acid derivative, identified as 1,2,3,4,6-penta-O-galloyl-{beta}-D-glucose (PGG), after thorough NMR and MS spectral analysis. Finally, this compound was tested against trypomastigote forms of T. cruzi and displayed an EC{sub 50} value of 67 {mu}M, at least 6.6-fold more effective than the standard drug benznidazole. This is the first occurrence of PGG in the Plectranthus genus and the first anti-parasitic activity described for PGG in the literature (author)

    Findings from a longitudinal study are presented on the relationships between the problems and stresses resulting from Hurricane Andrew and posthurricane minor deviant behavior. The sample (N = 4,978) included Hispanic, African-American, and White non-Hispanic middle school students enrolled in Dade County, Florida public schools. Two waves of data were collected prior to the hurricane; a third was obtained approximately 6 months following the storm. Results indicated that females were likely to report higher levels of hurricane-related stress symptoms than males. After controlling for prehurricane levels of minor deviance, family support, and race/ethnicity, hurricane stress symptom level remained a significant predictor of posthurricane minor deviant behavior. The findings lend support to stress theories of social deviance. PMID:9018678

    SUMOylation, the conjugation of target proteins with SUMO (small ubiquitin-related modifier), is a type of post-translational modification in eukaryotes and involves the sequential action of activation (E1), conjugation (E2) and ligation (E3) enzymes. In Arabidopsis, the AtSIZ1 protein is a SUMO E3 ligase that promotes the conjugation of SUMO proteins to target substrates. Here, we isolated and identified a SUMO E3 ligase, MdSIZ1, in apple, which was similar to AtSIZ1. SUMOylation analysis showed that MdSIZ1 had SUMO E3 ligase activity in vitro and in vivo. SUMO conjugation was increased by high temperatures, low temperatures, and abscisic acid (ABA). The ectopic expression of MdSIZ1 in Arabidopsis siz1-2 mutant plants partially complemented the morphological mutant phenotype and enhanced the levels of SUMO conjugation. Taken together, these results suggest that MdSIZ1-mediated SUMO conjugation of target proteins is an important process that regulates the adaptation of apple plants to various environmental stresses.

    Even low concentrations of endotoxins can be life-threatening. As such, continuous effort has been directed toward the development of sensitive and specific endotoxin detection systems. In this paper, we report the design and fabrication of a new electrochemical endotoxin sensor based on a human recombinant toll-like receptor 4 (rhTLR4) and myeloid differentiation-2 (MD-2) complex. The rhTLR4/MD-2 complex, which specifically binds to endotoxin, was immobilized on gold electrodes through a self-assembled monolayer (SAM) technique involving the use of dithiobis(succinimidyl undecanoate) (DSU). The surface topography of the electrodes at each fabrication stage was characterized with a nanosurface profiler and atomic force microscope (AFM). The electrochemical signals generated from interactions between the rhTLR4/MD-2 complex and the endotoxin were characterized by cyclic voltammetry (CV) and differential pulse voltammetry (DPV). A linear relationship between the peak current and endotoxin concentration was obtained in the range of 0.0005 to 5 EU/mL with a correlation coefficient (R(2)) of 0.978. The estimated limit of detection (LOD) was fairly low, 0.0002 EU/mL. The rhTLR4/MD-2 based sensors exhibited no current responses to dipalmitoylphosphatidylcholine (DPPC) bearing two lipid chains, which is structurally similar to endotoxin, indicating the high specificity of the sensors to endotoxin.

  12. Identification of key residues that confer Rhodobacter sphaeroides LPS activity at horse TLR4/MD-2.

    Directory of Open Access Journals (Sweden)

    Katherine L Irvine

    Full Text Available The molecular determinants underpinning how hexaacylated lipid A and tetraacylated precursor lipid IVa activate Toll-like receptor 4 (TLR4 are well understood, but how activation is induced by other lipid A species is less clear. Species specificity studies have clarified how TLR4/MD-2 recognises different lipid A structures, for example tetraacylated lipid IVa requires direct electrostatic interactions for agonism. In this study, we examine how pentaacylated lipopolysaccharide from Rhodobacter sphaeroides (RSLPS antagonises human TLR4/MD-2 and activates the horse receptor complex using a computational approach and cross-species mutagenesis. At a functional level, we show that RSLPS is a partial agonist at horse TLR4/MD-2 with greater efficacy than lipid IVa. These data suggest the importance of the additional acyl chain in RSLPS signalling. Based on docking analysis, we propose a model for positioning of the RSLPS lipid A moiety (RSLA within the MD-2 cavity at the TLR4 dimer interface, which allows activity at the horse receptor complex. As for lipid IVa, RSLPS agonism requires species-specific contacts with MD-2 and TLR4, but the R2 chain of RSLA protrudes from the MD-2 pocket to contact the TLR4 dimer in the vicinity of proline 442. Our model explains why RSLPS is only partially dependent on horse TLR4 residue R385, unlike lipid IVa. Mutagenesis of proline 442 into a serine residue, as found in human TLR4, uncovers the importance of this site in RSLPS signalling; horse TLR4 R385G/P442S double mutation completely abolishes RSLPS activity without its counterpart, human TLR4 G384R/S441P, being able to restore it. Our data highlight the importance of subtle changes in ligand positioning, and suggest that TLR4 and MD-2 residues that may not participate directly in ligand binding can determine the signalling outcome of a given ligand. This indicates a cooperative binding mechanism within the receptor complex, which is becoming increasingly

  2. Assessing the allelotypic effect of two aminocyclopropane carboxylic acid synthase-encoding genes MdACS1 and MdACS3a on fruit ethylene production and softening in Malus

    Science.gov (United States)

    Dougherty, Laura; Zhu, Yuandi; Xu, Kenong

    2016-01-01

    Phytohormone ethylene largely determines apple fruit shelf life and storability. Previous studies demonstrated that MdACS1 and MdACS3a, which encode 1-aminocyclopropane-1-carboxylic acid synthases (ACS), are crucial in apple fruit ethylene production. MdACS1 is well-known to be intimately involved in the climacteric ethylene burst in fruit ripening, while MdACS3a has been regarded a main regulator for ethylene production transition from system 1 (during fruit development) to system 2 (during fruit ripening). However, MdACS3a was also shown to have limited roles in initiating the ripening process lately. To better assess their roles, fruit ethylene production and softening were evaluated at five time points during a 20-day post-harvest period in 97 Malus accessions and in 34 progeny from 2 controlled crosses. Allelotyping was accomplished using an existing marker (ACS1) for MdACS1 and two markers (CAPS866 and CAPS870) developed here to specifically detect the two null alleles (ACS3a-G289V and Mdacs3a) of MdACS3a. In total, 952 Malus accessions were allelotyped with the three markers. The major findings included: The effect of MdACS1 was significant on fruit ethylene production and softening while that of MdACS3a was less detectable; allele MdACS1–2 was significantly associated with low ethylene and slow softening; under the same background of the MdACS1 allelotypes, null allele Mdacs3a (not ACS3a-G289V) could confer a significant delay of ethylene peak; alleles MdACS1–2 and Mdacs3a (excluding ACS3a-G289V) were highly enriched in M. domestica and M. hybrid when compared with those in M. sieversii. These findings are of practical implications in developing apples of low and delayed ethylene profiles by utilizing the beneficial alleles MdACS1-2 and Mdacs3a. PMID:27231553

    Tonoplast transporters, including proton pumps and secondary transporters, are essential for plant cell function and for quality formation of fleshy fruits and ornamentals. Vacuolar transport of anthocyanins, malate, and other metabolites is directly or indirectly dependent on the H(+)-pumping activities of vacuolar H(+)-ATPase (VHA) and/or vacuolar H(+)-pyrophosphatase, but how these proton pumps are regulated in modulating vacuolar transport is largely unknown. Here, we report a transcription factor, MdMYB1, in apples that binds to the promoters of two genes encoding the B subunits of VHA, MdVHA-B1 and MdVHA-B2, to transcriptionally activate its expression, thereby enhancing VHA activity. A series of transgenic analyses in apples demonstrates that MdMYB1/10 controls cell pH and anthocyanin accumulation partially by regulating MdVHA-B1 and MdVHA-B2. Furthermore, several other direct target genes of MdMYB10 are identified, including MdVHA-E2, MdVHP1, MdMATE-LIKE1, and MdtDT, which are involved in H(+)-pumping or in the transport of anthocyanins and malates into vacuoles. Finally, we show that the mechanism by which MYB controls malate and anthocyanin accumulation in apples also operates in Arabidopsis (Arabidopsis thaliana). These findings provide novel insights into how MYB transcription factors directly modulate the vacuolar transport system in addition to anthocyanin biosynthesis, consequently controlling organ coloration and cell pH in plants.

    Marek's disease virus (MDV) GX0101 is a field strain of MDV with a naturally occurring insertion of the reticuloendotheliosis virus (REV) long terminal repeat (LTR) fragment. Both copies of the meq gene were knocked out in the GX0101 bacterial artificial chromosome (BAC) clone to construct the recombinant virus SC9-1, resulting in a complete lack of pathogenicity and providing better protection against MD than CVI988/Rispens. In the present study, the BAC sequences in SC9-1 were removed using a cre-loxP system, and the virus termed SC9-2. SC9-2 showed a significant increase in replication in vitro and in vivo. There was a significant decrease in chicken weight, immune organ index, and antibody levels compared with those of SC9-1-inoculated chickens. The immune protection index of SC9-2 was similar to that of SC9-1, and the difference was not significant. The results of our studies demonstrate that the SC9-2 virus provides protection in specific pathogen free (SPF) chickens when challenged with a very virulent MDV rMd5, but it induces immunosuppressive effects in SPF chickens.

    Biliary atresia (BA) is the leading cause of pediatric end-stage liver disease in the United States. Education of parents in the perinatal period with stool cards depicting acholic and normal stools has been associated with improved time-to-diagnosis and survival in BA. PoopMD is a mobile application that utilizes a smartphone's camera and color recognition software to analyze an infant's stool and determine if additional follow-up is indicated. PoopMD was developed using custom HTML5/CSS3 and wrapped to work on iOS and Android platforms. In order to define the gold standard regarding stool color, seven pediatricians were asked to review 45 photographs of infant stool and rate them as acholic, normal, or indeterminate. Samples for which 6+ pediatricians demonstrated agreement defined the gold standard, and only these samples were included in the analysis. Accuracy of PoopMD was assessed using an iPhone 5s with incandescent lighting. Variability in analysis of stool photographs as acholic versus normal with intermediate rating weighted as 50% agreement (kappa) was compared between three laypeople and one expert user. Variability in output was also assessed between an iPhone 5s and a Samsung Galaxy S4, as well as between incandescent lighting and compact fluorescent lighting. Six-plus pediatricians agreed on 27 normal and 7 acholic photographs; no photographs were defined as indeterminate. The sensitivity was 7/7 (100%). The specificity was 24/27 (89%) with 3/27 labeled as indeterminate; no photos of normal stool were labeled as acholic. The Laplace-smoothed positive likelihood ratio was 6.44 (95% CI 2.52 to 16.48) and the negative likelihood ratio was 0.13 (95% CI 0.02 to 0.83). kappauser was 0.68, kappaphone was 0.88, and kappalight was 0.81. Therefore, in this pilot study, PoopMD accurately differentiates acholic from normal color with substantial agreement across users, and almost perfect agreement across two popular smartphones and ambient light settings.

    2014-01-01

    Photoionization models obtained with numerical codes are widely used to study the physics of the interstellar medium (Planetary Nebulae, H II regions, etc). Grid of models are performed to understand what are the effects of the different parameters used to describe the regions on the observables (mainly emission line intensities). Most of the time, only a small part of the computed results of such grids are published, and they are sometimes hard to obtain in a user-friendly format. We present here the Mexican Million Models dataBase (3MdB), an effort of resolving both of these issues in the form of a database of photoionization models, easily accessible throught the MySQL protocol, and containing a lot of usefull outputs from the models, such as the intensities of 178 emission lines, the ionic fractions of all the ions, etc. Some examples of the use of the 3MdB are also presented.

  20. Prevalence of mood disorders and utility of the PRIME-MD in patients undergoing radiation therapy

    International Nuclear Information System (INIS)

    Purpose: To validate a short, structured interview procedure that allows practicing oncologists to quickly and reliably identify mood disorders in their patients, and to estimate the prevalence and types of mood disorders in a radiation therapy patient setting, noting relationships between mood disorders and patient characteristics. Methods: Consecutive, eligible adult patients from the practices of two radiation oncologists were administered the Primary Care Evaluation of Mental Disorders (PRIME-MD) by the treating physician. A subset of these patients was also evaluated with the SCID, administered by trained mental health care personnel. Agreement between the two instruments was examined using the kappa statistic. Prevalence of mood disorders was determined from the PRIME-MD. The significance of relationships between patient characteristics and mood disorders was examined by chi-square and ANOVA analysis, and subsequently by multivariate logistic regression analysis. Results: One hundred twenty-two patients were studied. Fifty-three of these were administered the SCID. Agreement between the two instruments was very good (kappa = 0.70). A diagnosis of a depressive or anxiety disorder by the PRIME-MD was made in 59 of the 122 patients (48%, 95% confidence interval = 39%, 58%). Multivariate analysis showed that a diagnosis of a depressive mood disorder was significantly related to pain intensity and prior history of depression. Conclusion: We have demonstrated the validity and feasibility of the PRIME-MD administered by oncologists in making diagnoses of mood disorders. The prevalence of mood disorders in our set of patients undergoing a course of RT was nearly 50%. Future studies should describe the natural history of these disorders, and determine optimal intervention strategies

  2. Investigation on single carbon atom transporting through the single-walled carbon nanotube by MD simulation

    International Nuclear Information System (INIS)

    The single carbon atom transporting through the single-walled carbon nanotube has been studied by molecular-dynamics (MD) simulation. We got different trajectories of the carbon atom by changing the input parameters. The simulation results indicate that the single carbon atom with low energy can transport through the carbon nanotube under some input conditions and result in different trajectories being straight line or 'rosette' or circular.

  3. An Efficient Hybrid DSMC/MD Algorithm for Accurate Modeling of Micro Gas Flows

    KAUST Repository

    Liang, Tengfei

    2013-01-01

    Aiming at simulating micro gas flows with accurate boundary conditions, an efficient hybrid algorithmis developed by combining themolecular dynamics (MD) method with the direct simulationMonte Carlo (DSMC)method. The efficiency comes from the fact that theMD method is applied only within the gas-wall interaction layer, characterized by the cut-off distance of the gas-solid interaction potential, to resolve accurately the gas-wall interaction process, while the DSMC method is employed in the remaining portion of the flow field to efficiently simulate rarefied gas transport outside the gas-wall interaction layer. A unique feature about the present scheme is that the coupling between the two methods is realized by matching the molecular velocity distribution function at the DSMC/MD interface, hence there is no need for one-toone mapping between a MD gas molecule and a DSMC simulation particle. Further improvement in efficiency is achieved by taking advantage of gas rarefaction inside the gas-wall interaction layer and by employing the "smart-wall model" proposed by Barisik et al. The developed hybrid algorithm is validated on two classical benchmarks namely 1-D Fourier thermal problem and Couette shear flow problem. Both the accuracy and efficiency of the hybrid algorithm are discussed. As an application, the hybrid algorithm is employed to simulate thermal transpiration coefficient in the free-molecule regime for a system with atomically smooth surface. Result is utilized to validate the coefficients calculated from the pure DSMC simulation with Maxwell and Cercignani-Lampis gas-wall interaction models. ©c 2014 Global-Science Press.

    2009-01-01

    A multiscale approach, Molecular Dynamics/Order Parameter eXtrapolation (MD/OPX), to the all-atom simulation of large bionanosystems is presented. The approach starts with the introduction of a set of order parameters (OPs) automatically generated with orthogonal polynomials to characterize the nanoscale features of bionanosystems. The OPs are shown to evolve slowly via Newton’s equations and the all-atom multiscale analysis (AMA) developed earlier1 demonstrates the existence of their stochas...

  8. Why is mu/md so much smaller than mc/ms and mt/mb?

    International Nuclear Information System (INIS)

    We propose that the smallness of mu/md is due to the ''wrong'' Yukawa coupling of the up quark in a two-Higgs-doublet model. The model has natural flavor conservation only among charges -1/3 quarks and leptons. We estimate that D0-bar D 0 mixing is much larger than the value of the standard-model box diagrams, and could be larger than or comparable to the long-distance contributions,

  9. Hybrid Pressure Retarded Osmosis−Membrane Distillation (PRO−MD) Process for Osmotic Power and Clean Water Generation

    KAUST Repository

    Han, Gang

    2015-05-20

    A novel pressure retarded osmosis−membrane distillation (PRO−MD) hybrid process has been experimentally conceived for sustainable production of renewable osmotic power and clean water from various waters. The proposed PRO−MD system may possess unique advantages of high water recovery rate, huge osmotic power generation, well controlled membrane fouling, and minimal environmental impacts. Experimental results show that the PRO−MD hybrid process is promising that not only can harvest osmotic energy from freshwater but also from wastewater. When employing a 2 M NaCl MD concentrate as the draw solution, ultrahigh power densities of 31.0 W/m2 and 9.3 W/m2 have been demonstrated by the PRO subsystem using deionized water and real wastewater brine as the feeds, respectively. Simultaneously, high purity potable water with a flux of 32.5−63.1 L/(m2.h) can be produced by the MD subsystem at 40−60 °C without any detrimental effects of fouling. The energy consumption in the MD subsystem might be further reduced by applying a heat exchanger in the hybrid system and using low-grade heat or solar energy to heat up the feed solution. The newly developed PRO−MD hybrid process would provide insightful guidelines for the exploration of alternative green technologies for renewable osmotic energy and clean water production.

    Background The assessment of fitness to drive in patients with cognitive impairment is complex. The SIMARD MD was developed to assist with assessing fitness to drive. This study compares the clinical decision made by a geriatrician regarding driving with the SIMARD MD score. Methods Patients with a diagnosis of mild dementia or mild cognitive impairment, who had a SIMARD MD test, were included in the sample. A retrospective chart review was completed to gather diagnosis, driving status, and cognitive and functional information. Results Sixty-three patients were identified and 57 met the inclusion criteria. The mean age was 77.1 years (SD 8.9). The most common diagnosis was Alzheimer’s disease in 22 (38.6%) patients. The mean MMSE score was 24.9 (SD 3.34) and the mean MoCA was 19.9 (SD 3.58). The mean SIMARD MD score was 37.2 (SD 19.54). Twenty-four patients had a SIMARD MD score ≤ 30, twenty-eight between 31–70, and five scored > 70. The SIMARD MD scores did not differ significantly compared to the clinical decision (ANOVA p value = 0.14). Conclusions There was no association between the SIMARD MD scores and the geriatricians’ clinical decision regarding fitness to drive in persons with mild dementia or mild cognitive impairment.

  12. A Discussion on Governmental Research Grants.

    Science.gov (United States)

    Fang, Hui

    2015-10-01

    Governmental research grants are financially supported by taxpayers to meet financial requirements of research, particularly research that is unlikely to be supported by private funds. Researchers reward donors by producing knowledge. Publishing research results in an academic journal reflects achievement by researchers; however, receiving a grant award does not. The latter only provides the researcher with the capacity to perform his/her research. Applicants may receive more financial support than they actually need because there is no strict audit on the amount of money requested by each research proposal. There are fewer opportunities to apply for a governmental grant than there are for publishing an academic article, and the application process for governmental grants is not flexible. Some potentially innovative research may be impeded by the intense competition among scientific researchers applying for financial support. Researchers face stiffer competition at this stage than at the stage of publishing results. This paper suggests that scientific foundations can improve their efficiency by giving funding preference to economic proposals. Methods for estimating the efficiency of grants are proposed. The practice followed by the Small Grants for Exploratory Research programme of the National Science Foundation validates my analysis and recommendations. PMID:25143309

  13. Granting silence to avoid wireless collisions

    KAUST Repository

    Choi, Jung Il

    2010-10-01

    We describe grant-to-send, a novel collision avoidance algorithm for wireless mesh networks. Rather than announce packets it intends to send, a node using grant-to-send announces packets it expects to hear others send. We present evidence that inverting collision avoidance in this way greatly improves wireless mesh performance. Evaluating four protocols from 802.11 meshes and 802.15.4 sensor networks, we find that grant-to-send matches or outperforms CSMA and RTS/CTS in all cases. For example, in a 4-hop UDP flow, grantto- send can achieve 96% of the theoretical maximum throughput while maintaining a 99.9% packet delivery ratio. Grant-tosend is also general enough to replace protocol-specific collision avoidance mechanisms common to sensor network protocols. Grant-to-send is simple. For example, incorporating it into 802.11 requires only 11 lines of driver code and no hardware changes. Furthermore, as it reuses existing 802.11 mechanisms, grant-to-send inter-operates with current networks and can be incrementally deployed. © 2010 IEEE.

  14. Going beyond clustering in MD trajectory analysis: an application to villin headpiece folding.

    Directory of Open Access Journals (Sweden)

    Aruna Rajan

    Full Text Available Recent advances in computing technology have enabled microsecond long all-atom molecular dynamics (MD simulations of biological systems. Methods that can distill the salient features of such large trajectories are now urgently needed. Conventional clustering methods used to analyze MD trajectories suffer from various setbacks, namely (i they are not data driven, (ii they are unstable to noise and changes in cut-off parameters such as cluster radius and cluster number, and (iii they do not reduce the dimensionality of the trajectories, and hence are unsuitable for finding collective coordinates. We advocate the application of principal component analysis (PCA and a non-metric multidimensional scaling (nMDS method to reduce MD trajectories and overcome the drawbacks of clustering. To illustrate the superiority of nMDS over other methods in reducing data and reproducing salient features, we analyze three complete villin headpiece folding trajectories. Our analysis suggests that the folding process of the villin headpiece is structurally heterogeneous.

    The collective properties of the nuclear materials are defined as standard industrial codes such as ASME codes. While in service, the materials are aged and degraded, and the initial properties are changed according to the operating environments. These changes are a matter of substantial concern of the operators, regulators, and researchers in nuclear fields. Hence, the material property database considering the degradation is required, and the successful management and use of material property information must be responsive to the continuing changes and increasing complexity in nuclear engineering materials. Recently, the nuclear materials division in the Korea Atomic Energy Research Institute (KAERI) launched a comprehensive portal website for nuclear material information, which is known as the MD-portal. The MD-portal contains various technical documents on the degradation and development of nuclear materials. Additionally, the nuclear materials database (MatDB) is incorporated in it. The MatDB covers the mechanical properties of various nuclear structural materials used as the components: a reactor pressure vessel, steam generator, and primary and secondary piping. In this study, we introduced the MD-portal MatDB briefly, and showed an application of the MatDB to the real case of material degradations in NPPs.

  19. Principal component and Tucker3 analyses of high performance liquid chromatography with diode-array detection fingerprints of crude extracts of Erythrina speciosa Andrews leaves

    International Nuclear Information System (INIS)

    Highlights: ► Simultaneous chromatographic, spectroscopic and mixture proportion correlations. ► Tucker3 analysis of chromatographic, spectral and solvent mixture proportions. ► HPLC-DAD spectral characterization of chromatographic peaks. - Abstract: Mixtures of ethanol, dichloromethane, hexane and acetone obtained according to a statistical design have been used to extract substances from Erythrina speciosa Andrew leaves for chromatographic fingerprinting. The plant extracts from each mixture were analyzed by HPLC-DAD providing UV–vis spectra for each chromatographic peak. These chromatograms and spectra for the design mixtures were then treated with principal component (PCA), Tucker3 and PARAFAC analyses. PCA indicated the existence of five different chromatographic fingerprints for the leave extracts depending on the solvent mixture composition. Different chromatographic peak areas were strongly correlated with the mixture proportions of acetone, dichloromethane and ethanol. Tucker3 and PARAFAC analyses were very useful for identifying simultaneous correlations between chromatographic peak areas, spectral band absorbances and solvent proportions. The acetone proportion was highly correlated with the area of the 3.69 min retention time peak and the spectral absorbances between 250 and 260 nm, consistent with the presence of natural polyphenols. The dichloromethane mixture proportion was strongly correlated with the 12.19 min chromatographic peak area and a single spectral absorbance at 201 nm. This spectral absorption is characteristic of the electronic structures of terpenes and alkaloids.

    Although competitive funding of public research has been characterised as providing output incentives that raise efficiency and productivity, we know very little about whether the quality of a scientist’s research is in fact the primary award criterion on which funding bodies base their grant...... decision. This paper provides insights into scientists’ strategies for obtaining project-based research funding in the presence of multiple funding opportunities. It draws a distinction between four types of grants, including the Sixth Framework Programme for Research and Technological Development (FP6......), government, foundation, and industry grants. Based on a sample of more than 800 scientists at universities and public research institutes in Germany, the results indicate that scientist productivity measured in terms of publication and patent stock is a statistically significant determinant only...

  8. The MD Design - a cool concept for geologic disposal of radioactive waste

    International Nuclear Information System (INIS)

    The scheduled disposal capacity for spent nuclear fuel and other high-level radioactive wastes (HLW) is inadequate and the estimated supply of recoverable uranium for continued nuclear energy production is scarce in the beginning of the 21st century. Hence, the development of a safe method for permanent disposal of HLW is an imminent global imperative to the continued development and use of nuclear energy, as is the prudent use of available uranium resources. However, permanent disposal of HLW poses a potential long-term public health and environmental hazard (risk) presenting unprecedented scientific challenges as well as moral, ethical and political concerns. The Minimum Disturbance to the Geologic Setting (MD) Design is an integrated, generic, low-temperature (cool), cradle-to-grave, radioactive waste management system for safe geologic disposal of radioactive waste. The application of the MD Design introduced in this paper is a safe and cost-effective geologic repository for permanent disposal of HLW. The main safety features are: Highly focused site selection and site characterization; mechanical mining; maximum near-field geologic setting temperature of 90 degrees Centigrade (degrees C) (194 degrees Fahrenheit [degrees F]); long-term primary (substantial) radionuclide containment by the engineered barriers system (EBS); long-term near-field monitoring; and a three-tiered licensing process. The main cost-effective features are: Concurrent construction and operation; remote controlled handling and in-room emplacement of HLW; and ready long-term access to the emplaced HLW. The unique combination of new and old safety and HLW disposal concepts in the MD Design offers potential solutions to three global HLW disposal problems; credible validation of safety assessments; enhanced HLW disposal capacity; and ready long-term access to a reusable, scarce natural energy resource - uranium

    Leadership skills are essential for a successful career as a physician-scientist, yet many MD-PhD training programs do not offer formal training in leadership. The Vanderbilt Medical Scientist Training Program (MSTP) previously established a 2-day leadership workshop that has been held biennially since 2006 for students in the first and second years of the graduate school portion of combined MD and PhD training (G1/G2 students). Workshop attendees have consistently rated this workshop as a highly effective experience. However, opportunities for structured training in leadership competencies during the subsequent 3-5 years of MD-PhD training are limited. Given the success of the G1/G2 leadership workshop and the need for continuity in this model of leadership training, we developed a half-day workshop for MSTP students in the clinical years of medical school (M3/M4 students) to foster continued training in leadership. Our workshop curriculum, based in part on original cases drafted by Vanderbilt MSTP students, provides concrete strategies to manage conflict and navigate leadership transitions in the physician-scientist career path. The curriculum emphasizes both short-term competencies, such as effective participation as a member of a clinical team, and long-term competencies, such as leadership of a research team, division, or department. Our inaugural senior leadership workshop, held in August, 2015, was judged by student participants to be well organized and highly relevant to leadership concepts and skills. It will be offered biennially in our training curriculum for M3 and M4 MSTP students. PMID:27499363

  10. Constant-pH MD Simulations of an Oleic Acid Bilayer.

    Oleic acid is a simple molecule with an aliphatic chain and a carboxylic group whose ionization and, consequently, intermolecular interactions are strongly dependent on the solution pH. The titration curve of these molecules was already obtained using different experimental methods, which have shown the lipid bilayer assemblies to be stable between pH 7.0 and 9.0. In this work, we take advantage of our recent implementations of periodic boundary conditions in Poisson-Boltzmann calculations and ionic strength treatment in simulations of charged lipid bilayers, and we studied the ionization dependent behavior of an oleic acid bilayer using a new extension of the stochastic titration constant-pH MD method. With this new approach, we obtained titration curves that are in good agreement with the experimental data. Also, we were able to estimate the slope of the titration curve from charge fluctuations, which is an important test of thermodynamic consistency for the sampling in a constant-pH MD method. The simulations were performed for ionizations up to 50%, because an experimentally observed macroscopic transition to micelles occurs above this value. As previously seen for a binary mixture of a zwitterionic and an anionic lipid, we were able to reproduce experimental results with simulation boxes usually far from neutrality. This observation further supports the idea that a charged membrane strongly influences the ion distribution in its vicinity and that neutrality is achieved significantly far from the bilayer surface. The good results obtained with this extension of the stochastic titration constant-pH MD method strongly supports its usefulness to sample the coupling between configuration and protonation in these types of biophysical systems. This method stands now as a powerful tool to study more realistic lipid bilayers where pH can influence both the lipids and the solutes interacting with them. PMID:26574431

    The landscape of combined baccalaureate-MD programs has changed substantially in the last two decades but has not been documented in detail. The authors review the current state of these programs and discuss opportunities for future study of their evolving role and potential impact.In 2011, using a definition of baccalaureate-MD program built on prior research, the authors reviewed Association of American Medical Colleges sources and medical school Web sites to identify and characterize 81 active programs. In addition, they surveyed the 57 medical schools offering those programs; 31 schools with 39 programs responded. The resulting database inventories the number and distribution of programs; institutional affiliations; missions or goals; length; size; admissions criteria; curricula; and retention requirements.Since the inception of combined programs in 1961, their number and curricular length have increased. Pressures that spurred earlier programs remain evident in the goals of today's programs: attract talented high school or early college students, especially from diverse backgrounds; prepare physicians to meet societal needs; and offer an enriched premedical environment. Baccalaureate educational activities achieve program goals through special courses, medical experiences, community service, and learning communities tailored to students' needs. Admission and retention criteria are comparable to those of traditional medical schools.Combined baccalaureate-MD programs have evolved along several paths during the last half century and have enriched the baccalaureate experiences of medical students. Shifting expectations for the selection and education of future physicians warrant focused research on these programs to document their effectiveness in addressing those expectations. PMID:23018320

  12. Understanding the mechanism of LCST phase separation of mixed ionic liquids in water by MD simulations.

    Recently, it has been found experimentally that two different amino acid ionic liquids (ILs) can be mixed to show unique lowest critical solution temperature (LCST) phase separation in water. However, little is known about the mechanism of phase separation in these IL/water mixtures at the molecular level. In this work, five kinds of amino acid ILs were chosen to study the mechanism of LCST-type phase separation by molecular dynamics (MD) simulations. Toward this end, a series of all-atom MD simulations were carried out on the ternary mixtures consisting of two different ILs and water at different temperatures. The various interaction energies and radial distribution functions (RDFs) were calculated and analyzed for these mixed systems. It was found that for amino acid ILs, the -NH2 or -COOH group of one anion could have a hydrogen bonding interaction with the -COO(-) group of another anion. With the increase of temperature, this kind of hydrogen bonding interaction between anions was strengthened and then the anion-H2O electrostatic interaction was weakened, which led to the LCST-type phase separation of the mixed ILs in water. In addition, a series of MD simulations for [P6668]1[Lys]n[Asp]1-n/H2O systems were also performed to study the effect of the mixing ratio of ILs on phase separation. It was also noted that the experimental critical composition corresponding to the lowest critical solution temperature was well predicted from the total electrostatic interaction energies as a function of mole fraction of [P6668][Lys] in these systems. The conclusions drawn from this study may provide new insight into the LCST-type phase behavior of ILs in water, and motivate further studies on practical applications. PMID:27498928

    We determine the liquid-solid phase diagram for carbon-oxygen and oxygen-selenium plasma mixtures using two-phase MD simulations. We identified liquid, solid, and interface regions using a bond angle metric. To study finite size effects, we perform 27648 and 55296 ion simulations. To help monitor non-equilibrium effects, we calculate diffusion constants $D_i$. For the carbon-oxygen system we find that $D_O$ for oxygen ions in the solid is much smaller than $D_C$ for carbon ions and that both ...

  15. Neutron emission as a function of fragment energy in the spontaneous fission of 260Md

    International Nuclear Information System (INIS)

    The authors have made the first measurement of the number of neutrons emitted in the spontaneous fission of a nuclide in which very high fragment energies dominate the fission process. In bombardments of 254Es, they produced 28-d 260Md, which was neutron-counted in a 1-m-diam spherical tank containing a Gd-doped scintillator solution. The average number of neutrons emitted per fission is only 2.58 ± 0.11, substantially less than for other actinides. A direct correlation of neutron multiplicity with fragment excitation energy is clearly demonstrated

  19. Dynamics of biopolymers on nanomaterials studied by quasielastic neutron scattering and MD simulations

    Science.gov (United States)

    Dhindsa, Gurpreet K.

    Neutron scattering has been proved to be a powerful tool to study the dynamics of biological systems under various conditions. This thesis intends to utilize neutron scattering techniques, combining with MD simulations, to develop fundamental understanding of several biologically interesting systems. Our systems include a drug delivery system containing Nanodiamonds with nucleic acid (RNA), and two specific model proteins, beta-Casein and Inorganic Pyrophosphatase (IPPase). RNA and nanodiamond (ND) both are suitable for drug-delivery applications in nano-biotechnology. The architecturally flexible RNA with catalytic functionality forms nanocomposites that can treat life-threatening diseases. The non-toxic ND has excellent mechanical and optical properties and functionalizable high surface area, and thus actively considered for biomedical applications. In this thesis, we utilized two tools, quasielastic neutron scattering (QENS) and Molecular Dynamics Simulations to probe the effect of ND on RNA dynamics. Our work provides fundamental understanding of how hydrated RNA motions are affected in the RNA-ND nanocomposites. From the experimental and Molecular Dynamics Simulation (MD), we found that hydrated RNA motion is faster on ND surface than a freestanding one. MD Simulation results showed that the failure of Stokes Einstein relation results the presence of dynamic heterogeneities in the biomacromolecules. Radial pair distribution function from MD Simulation confirmed that the hydrophilic nature of ND attracts more water than RNA results the de-confinement of RNA on ND. Therefore, RNA exhibits faster motion in the presence of ND than freestanding RNA. In the second project, we studied the dynamics of a natively disordered protein beta-Casein which lacks secondary structures. In this study, the temperature and hydration effects on the dynamics of beta-Casein are explored by Quasielastic Neutron Scattering (QENS). We investigated the mean square displacement (MSD) of

  2. Spatial distribution and compositional variation of APS minerals related to uranium deposits in the Kiggavik-Andrew Lake structural trend, Nunavut, Canada

    Science.gov (United States)

    Riegler, Thomas; Quirt, Dave; Beaufort, Daniel

    2016-02-01

    The Kiggavik-Andrew Lake structural trend consists of four mineralized zones, partially outcropping, lying 2 km south of the erosional contact with the unmetamorphosed sandstone and basal conglomerates of the Paleoproterozoic Thelon Formation. The mineralization is controlled by a major E-W fault system associated with illite and sudoite alteration halos developed in the Archean metagraywackes of the Woodburn Lake Group. Aluminum phosphate sulfate (APS) minerals from the alunite group crystallized in association with the clay minerals in the basement alteration halo as well as in the overlying sandstones, which underwent mostly diagenesis. APS minerals are Sr- and S-rich (svanbergite end-member) in the sedimentary cover overlying the unconformity, whereas they are light rare earth elements (LREE)-rich (florencite end-member) in the altered basement rocks below the unconformity. The geochemical signature of each group of APS minerals together with the petrography indicates three distinct generations of APS minerals related to the following: (1) paleoweathering of continental surfaces prior to the basin occurrence, (2) diagenetic processes during the burial history of the lower unit of the Thelon sandstones, and (3) hydrothermal alteration processes which accompanied the uranium deposition in the basement rocks and partially overlap the sedimentary-diagenetic mineral parageneses. In addition, the association of a first generation of APS minerals with both detrital cerium oxide and aluminum oxy-hydroxide highlights the fact that a part of the detrital material of the basal Thelon Formation originated from eroded paleolaterite (allochthonous regolith). The primary rare earth element (REE)-bearing minerals (e.g., monazite, REE carbonates, and allanite) of the host rocks were characterized to identify the potential sources of REE. The REE chemical composition highlights a local re-incorporation of the REE released from the alteration processes in the APS minerals of

    Highlights: • To verify design strength, EM and mechanical analysis was implemented. • During MD events, the radial force due to large eddy current is predominant. • We confirmed the VV structure is still strong enough even in the most severe condition. • Preliminary thermal calculation suggested suitable discharge parameters. -- Abstract: KTX is a new reversed field pinch (RFP) magnetic confinement device which is under design in ASIPP and USTC. Major disruption (MD) events may occur in future operating process, which is simulated with the finite element (FE) method. The results present that the peaks of eddy currents on vessel and conductor shell are respectively 11.791 kA and 68.637 kA with maximum stress 67.1 MPa due to high transient electromagnetic (EM) force. It is confirmed that the structure is still strong enough to bear the electromagnetic loads even if the worst case. Besides, as KTX vacuum vessel will take the method of natural cooling for heat dissipation during plasma discharge (0.5–1.0 MA), a preliminary thermal calculation was implemented in normal condition to decide suitable time parameters such as duration and interval. It is suggested that the discharge interval should be no less than 5 min for the complete 1 MA plasma with 100 ms duration, which can guarantee the temperature of vacuum vessel below 200 °C.

    A new externally deployable energy absorbing system was demonstrated during a full-scale crash test of an MD-500 helicopter. The deployable system is a honeycomb structure and utilizes composite materials in its construction. A set of two Deployable Energy Absorbers (DEAs) were fitted on the MD-500 helicopter for the full-scale crash demonstration. Four anthropomorphic dummy occupants were also used to assess human survivability. A demonstration test was performed at NASA Langley's Landing and Impact Research Facility (LandIR). The test involved impacting the helicopter on a concrete surface with combined forward and vertical velocity components of 40-ft/s and 26-ft/s, respectively. The objectives of the test were to evaluate the performance of the DEA concept under realistic crash conditions and to generate test data for validation of dynamic finite element simulations. Descriptions of this test as well as other component and full-scale tests leading to the helicopter test are discussed. Acceleration data from the anthropomorphic dummies showed that dynamic loads were successfully attenuated to within non-injurious levels. Moreover, the airframe itself survived the relatively severe impact and was retested to provide baseline data for comparison for cases with and without DEAs.

    We present adaptive optics imaging of the core collapse supernova (SN) 2009md, which we use together with archival HST data to identify a coincident progenitor candidate. We find the progenitor to have an absolute magnitude of $V = -4.63^{+0.3}_{-0.4}$ mag and a colour of $V-I = 2.29^{+0.25}_{-0.39}$ mag, corresponding to a progenitor luminosity of log $L$/\\lsun $\\sim4.3\\pm0.2$ dex. Using the stellar evolution code STARS, we find this to be consistent with a red supergiant progenitor with $M = 7_{-1}^{+5}$ \\msun. The photometric and spectroscopic evolution of SN 2009md is similar to that of the class of sub-luminous Type IIP SNe. We estimate the mass of $^{56}$Ni ejected in the explosion to be $(5.4\\pm1.3) \\times 10^{-3}$ \\msun\\ from the luminosity on the radioactive tail, which is in agreement with the low $^{56}$Ni masses estimated for other sub-luminous Type IIP SNe. Simple modeling of the SN is presented, where we include a constraint on the radius from progenitor observations. Using this modeling we find...

  6. Numerical simulations of magnetic materials with MD-GRAPE: curvature induced anisotropy

    International Nuclear Information System (INIS)

    The time development of an array of magnetic dipoles representing the internal magnetization of a thin film is calculated using a hardware accelerator, MD-GRAPE, for the determination of the magnetic vector potential. The results for single-layer arrays of dipoles are compared with the analogous results obtained from an FFT method and found to be in reasonable agreement. Three-dimensional MD-GRAPE simulations with sinusoidal deformations illustrate the utility of the hardware accelerator in cases that cannot be solved easily with FFT methods. The deformations give the internal field an asymmetry with components parallel to the wave crest, leading to significant changes in the critical external fields required for switching. These changes occur even for small wave amplitudes, comparable to or less than the layer thickness. Layer curvature affects the astroid pattern of critical field strengths by shifting the threshold to lower absolute values of the hard axis field when the curvature is in the easy axis direction, and lower absolute values of the easy axis field when the curvature is in the hard axis direction. This effect of curvature differs from orange peel coupling between two layers because here there is only one layer, and because orange peel coupling shifts the whole astroid pattern as a result of an effective field bias, whereas here the pattern shape is changed without any centroid shift

  7. Probing the Residual Structure in Avian Prion Hexarepeats by CD, NMR and MD Techniques

    Full Text Available Many proteins perform essential biological functions by means of regions that lacking specific organized structure exist as an ensemble of interconverting transient conformers. The characterization of such regions, including the description of their structural propensities, number of conformations and relative populations can provide useful insights. Prion diseases result from the conversion of a normal glycoprotein into a misfolded pathogenic isoform. The structures of mammal and chicken prion proteins show a similar fold with a globular domain and a flexible N-terminal portion that contains different repeated regions: octarepeats (PHGGGWGQ in mammals and hexarepeats (PHNPGY in chickens. The higher number of prolines in the hexarepeat region suggests that this region may retain a significant amount of residual secondary structure. Here, we report the CD, NMR and MD characterization of a peptide (2-HexaPY composed of two hexarepeats. We combine experimental NMR data and MD to investigate at atomic level its ensemble-averaged structural properties, demonstrating how each residue of both repeats has a different quantified PPII propensity that shows a periodicity along the sequence. This feature explains the absence of cooperativity to stabilize a PPII conformation. Nonetheless, such residual structure can play a role in nucleating local structural transitions as well as modulating intra-molecular or inter-molecular interactions.

  8. The embedded atom model and large-scale MD simulation of tin under shock loading

    International Nuclear Information System (INIS)

    The goal of the work was to develop an interatomic potential, that can be used in large-scale classical MD simulations to predict tin properties near the melting curve, the melting curve itself, and the kinetics of melting and solidification when shock and ramp loading. According to phase diagram, shocked tin melts from bcc phase, and since the main objective was to investigate melting, the EAM was parameterized for bcc phase. The EAM was optimized using isothermal compression data (experimental at T=300 K and ab-initio at T=0 K for bcc, fcc, bct structures), experimental and QMD data on the Hugoniot and on the melting at elevated pressures. The Hugoniostat calculations centred at β-tin at ambient conditions showed that the calculated Hugoniot is in good agreement with experimental and QMD data above p-bct transition pressure. Calculations of overcooled liquid in pressure range corresponding to bcc phase showed crystallization into bcc phase. Since the principal Hugoniot of tin originates from the β-tin that is not described by this EAM the special initial state of bcc samples was constructed to perform large-scale MD simulations of shock loading.

  9. Exploring the RING-catalyzed ubiquitin transfer mechanism by MD and QM/MM calculations.

    Ubiquitylation is a universal mechanism for controlling cellular functions. A large family of ubiquitin E3 ligases (E3) mediates Ubiquitin (Ub) modification. To facilitate Ub transfer, RING E3 ligases bind both the substrate and ubiquitin E2 conjugating enzyme (E2) linked to Ub via a thioester bond to form a catalytic complex. The mechanism of Ub transfer catalyzed by RING E3 remains elusive. By employing a combined computational approach including molecular modeling, molecular dynamics (MD) simulations, and quantum mechanics/molecular mechanics (QM/MM) calculations, we characterized this catalytic mechanism in detail. The three-dimensional model of dimeric RING E3 ligase RNF4 RING, E2 ligase UbcH5A, Ub and the substrate SUMO2 shows close contact between the substrate and Ub transfer catalytic center. Deprotonation of the substrate lysine by D117 on UbcH5A occurs with almost no energy barrier as calculated by MD and QM/MM calculations. Then, the side chain of the activated lysine gets close to the thioester bond via a conformation change. The Ub transfer pathway begins with a nucleophilic addition that forms an oxyanion intermediate of a 4.23 kcal/mol energy barrier followed by nucleophilic elimination, resulting in a Ub modified substrate by a 5.65 kcal/mol energy barrier. These results provide insight into the mechanism of RING-catalyzed Ub transfer guiding the discovery of Ub system inhibitors. PMID:25003393

  11. An MD-PhD program in Brazil: students’ concepts of science and of common sense

    2011-11-01

    Full Text Available In 1995, a pioneering MD-PhD program was initiated in Brazil for the training of medical scientists in experimental sciences at the Federal University of Rio de Janeiro. The program’s aim was achieved with respect to publication of theses in the form of papers with international visibility and also in terms of fostering the scientific careers of the graduates. The expansion of this type of program is one of the strategies for improving the preparation of biomedical researchers in Brazil. A noteworthy absence of interest in carrying out clinical research limits the ability of young Brazilian physicians to solve biomedical problems. To understand the students’ views of science, we used qualitative and quantitative triangulation methods, as well as participant observation to evaluate the students’ concepts of science and common sense. Subjective aspects were clearly less evident in their concepts of science. There was a strong concern about "methodology", "truth" and "usefulness". "Intuition", "creativity" and "curiosity" were the least mentioned thematic categories. Students recognized the value of intuition when it appeared as an explicit option but they did not refer to it spontaneously. Common sense was associated with "consensus", "opinion" and ideas that "require scientific validation". Such observations indicate that MD-PhD students share with their senior academic colleagues the same reluctance to consider common sense as a valid adjunct for the solution of scientific problems. Overcoming this difficulty may be an important step toward stimulating the interest of physicians in pursuing experimental research.

  3. Spatial and Temporal Trends in the Carbon, Nitrogen, and Sulfur Isotopes of Stream DOM From 10 Watersheds at the HJ Andrews Experimental Forest.

    2008-12-01

    In order to better understand sources of dissolved organic matter (DOM) in streams from the small to large watershed scales, we initiated a one-year investigation of the chemical and isotopic characteristics of DOM at the HJ Andrews Experimental Forest (HJA) in Blue River, OR. DOM is a biologically significant loss from these watersheds, but its sources (forest floor, mineral soil, riparian zones, stream biota) are debated. Traditional chemical characterizations of DOM like SUVA and FI have been useful in conceptualizing and modeling streamflow sources, however, an improved method for assessing DOM quality is needed to adequately differentiate DOM from sources within the watershed. The isotopic characterization of inorganic molecules like nitrate has provided insight to the role of subsurface and surface processes governing the production and transport of critical nutrients, and yet to date, little work has been done to examine the usefulness of isotopic characterization of organically bound nutrients. We apply the isotopic characterization approach to DOM in order to better understand DOM production, transformation, and transport to streams in a range of watershed sizes. Major questions addressed in this research are: 1) Where in the watershed does stream DOM come from? 2) How do DOM sources vary temporally? 3) How do physical attributes of the watershed mediate DOM quality? A relatively new solid-phase extraction technique using C-18 resin was used to isolate DOM in water samples from 10 watersheds, ranging in size from 10 to 6200 hectares, on 3-week intervals from May 2007 to June 2008. The modified technique allowed for small (1 Liter) sample sizes and short processing times to reduce the costs of analysis. The capacity of carbon, nitrogen and sulfur isotopic characterizations of DOM, as well as traditional methods like SUVA and C:N, to predict physical watershed attributes (i.e. mean residence time, soil depth, elevation, gradient) and land use history (timber

    多酚氧化酶(PPO)是一种含多个铜离子的氧化还原酶,可催化酚类物质氧化为醌类物质。我们从八棱海棠中克隆到一个PPO的同源基因MdPPO2B,构建该基因酵母分泌表达载体并转化到毕赤酵母GS115中。SDS-PAGE电泳结果显示,表达蛋白MdPPO2B的分子量约为66.4 kDa。以邻苯二酚作为底物,该酶的最适pH和温度分别为6.5和40℃。除Cu2+、Na+、Mg2+和Li+外,4 mmol·L-1的Fe3+、Zn2+、Mn2+对酶活力表现出较强的抑制作用。在最适条件下,当苯酚浓度达600μmol·L-1时,反应4 h, MdPPO2B表达菌株可降解80%的苯酚。表明该基因在工业污水处理中具有广阔的应用潜力。%Polyphenol oxidase (PPO) is one of oxidoreductase enzymes, which catalyzes the phenols to diqui-nones. A putative PPO gene (MdPPO2B) wascloned fromMalus robusta and exogenously expressed inPichia pastoris GS115. SDS-PAGE showed thatMdPPO2B has a molecular mass of approximately 66.4 kDa. With catechol as substrate, it was showed that the optimum pH and temperature forMdPPO2B was 6.5 and 40℃, respectively. Except for Cu2+, Na+, Mg2+ and Li+, Fe3+, Zn2+ and Mn2+ inhibited the enzyme activity at a concen-tration of 4 mmol·L-1. TheMdPPO2B degraded 80% phenol after incubated for 4 h under the optimum condi-tion. In short, our original research onMdPPO2B may provide reference for the application of microorganism in industrial wastewater.

    Kretov, D A

    2004-01-01

    Molecular Dynamics (MD) simulations have been performed on the parallel-vector and special-purposes MD machines to study the dynamical behaviors of a flexible polyethylene (PE) chain subjected to various heating conditions. Both the effect of the short-range and electrostatic interactions on the dynamics of the PE system were estimated and compared. For this purpose three different simulations were performed regarding on the following regimes: fast, moderate and slow heating processes. The peculiarities of the main thermodynamic quantities of the system were estimated in detail and compared for all three processes. Molecular mechanical and MD calculations on the PE system were performed using the optimized version of the DL_POLY code, adapted for the vector- and special-purpose MDGRAPE-2 machines.

    In poly-p-xylylene (parylene) AF4 membranes, amorphous and crystalline areas were constructed by a novel computational technique: a combination of NVT + NPT-molecular dynamics (MD) and "gradually reduce the size" (GRS) methods. The corresponding free volume was determined via the homology cluster method. Crystalline parylene AF4 membranes were found to provide less free volume for the adsorption and transfer of gases than amorphous parylene AF4. The permeability results showed that amorphous and crystalline parylene AF4 membranes have different permeation properties, and the corresponding permeability coefficients approach those observed experimentally. This work determined the behaviours and directions of diffusing gases via a cluster analysis technique. Gas diffusion occurs only along the y-axis in the crystalline area and randomly in the amorphous area. The relative permeability was close to the experimental value.

    Full Text Available Probe-based or mixed solvent molecular dynamics simulation is a useful approach for the identification and characterization of druggable sites in drug targets. However, thus far the method has been applied only to soluble proteins. A major reason for this is the potential effect of the probe molecules on membrane structure. We have developed a technique to overcome this limitation that entails modification of force field parameters to reduce a few pairwise non-bonded interactions between selected atoms of the probe molecules and bilayer lipids. We used the resulting technique, termed pMD-membrane, to identify allosteric ligand binding sites on the G12D and G13D oncogenic mutants of the K-Ras protein bound to a negatively charged lipid bilayer. In addition, we show that differences in probe occupancy can be used to quantify changes in the accessibility of druggable sites due to conformational changes induced by membrane binding or mutation.

    Full Text Available Communication in digital form has become the part of day today’s lifestyle, in certain moment communication is made secret to avoid others from knowing the information. By providing security to the sensitive data it is ensured that the user’s data is protected from viewing and accessing by others. In the current discussion about data security, Steganographic algorithm using two mediums has been discussed that involves image based encryption and converting to word file. The stage involving image based encryption uses HMAC-MD5 algorithm along with LSB steganography. LSB technique scatters the secret data which have to be protected over the entire image. Convert the embedded image in word file, so that the secret message is made unavailable to others who try to obtain the file. This method provides greater payload capacity along with higher image fidelity and thus make the proposed system is more robust against attacks. 

  14. Static and dynamic properties of confined, cold ion plasmas: MD (molecular dynamics) simulations

    Energy Technology Data Exchange (ETDEWEB)

    Schiffer, J.P.

    1989-01-01

    Some four years ago it was suggested that in the new generation of heavy ion accelerator storage rings for multiply charged ions, being planned in Europe, one may well attain internal temperatures that would correspond to very cold plasmas. Since that time, the techniques of electron or laser cooling of such beams has evolved and it may well be possible to reach temperatures corresponding to a plasma coupling parameter {Gamma} >> 100. I was fortunate to have had an opportunity to collaborate during 1986-87 with my former colleague Aneesur Rahman, of Molecular Dynamics fame, and we adapted the MD method to the calculation of the properties of cold confined plasmas. After Rahman's premature death two years ago I have continued the exploration of these systems and would like to summarize the results here. 9 refs., 10 figs.

    Development of the multimechanism deformation (M-D) constitutive model for steady state creep, which incorporates irreversible workhardening and recovery transient strains, was motivated by the need to predict very long term closures in underground rooms for radioactive waste repositories in salt. The multimechanism deformation model for the creep deformation of salt is extended to treat the response of salt to imposed stress drops. Stress drop tests produce a very distinctive behavior where both reversible elastic strain and reversible time dependent strain occur. These transient strains are negative compared to the positive transient strains produced by the normal creep workhardening and recovery processes. A simple micromechanical evolutionary process is defined to account for the accumulation of these reversible strains, and their subsequent release with decreases in stress. A number of experimental stress drop tests for various stress drop magnitudes and temperatures are adequately simulated with the model.

    In the funding of R&D, push mechanisms, such as research grants, subsidize research input, while pull mechanisms, such as innovation prizes, reward research output. By rewarding research output, pull mechanisms create strong incentives for researchers to devote non observable inputs to R&D. Push mechanisms, in contrast, may reward a researcher independently of her output. In the presence of moral hazard, it might seem that push mechanisms generate weak incentives for non observable inputs fro...

  4. Diffusion of hydrocarbon in zeolite and effect due to pore topology: Neutron scattering and MD simulation studies

    Highlights: • Dynamical landscape of propylene adsorbed in two different zeolites is obtained. • MD simulation indicated three different time scales for the translational motion. • Neutron scattering data correspond to one of the three different time scales. • Faster rotational motion observed in a wider energy window neutron spectrometer. • Propylene found to be in preferred orientation in ZSM5 but not in Na–Y zeolite. - Abstract: Here we report detailed dynamical landscape of propylene adsorbed in ZSM5 and Na–Y zeolites as studied by neutron scattering and molecular dynamics (MD) simulation. Separation of propylene molecule from propane in the petrochemical industry is an important issue because it is one of the most demanding energetic separation processes due to their very close relative volatilities and molecular sizes. Aim here is to investigate the correlation of the host topology towards the dynamics of guest molecules. ZSM5 zeolite is typified by a network of intersecting channels while Na–Y has a network of spherical supercages interconnected by windows. Both neutron scattering and MD simulation studies indicated that translational diffusion of propylene is more restricted in ZSM5 compared to Na–Y zeolite. Fully atomistic MD simulation studies showed that the translation involves three different time scales and rotational motion of the propylene is much faster than translation. The observed dynamics in QENS spectrometer (ΔE ∼ 200 μeV) corresponds to one of the three translational components indicated in the MD simulation. The faster rotational motion is observed in a wider energy window spectrometer (ΔE ∼ 3 meV). MD simulation results also show some interesting features like, non-isotropic rotation in ZSM5 while it has been isotropic in Na–Y zeolite. It is also found that propylene molecules prefer to orient along channels of ZSM5 zeolite.

    Membrane distillation (MD) is a promising separation technique capable of being used in the desalination of marine and brackish water. Poly(vinylidene fluoride) (PVDF) flat sheet nano-composite membranes were surface modified by coating with electro-spun PVDF nano-fibres to increase the surface hydrophobicity. For this purpose, the nano-composite membrane containing 7 wt.% superhydrophobic SiO2 nano-particles, which showed the highest flux in our previous work, was first subjected to pore size augmentation by increasing the concentration of the pore forming agent (Di-ionized water). Then, the prepared flat sheet membranes were subjected to nanofibres coating by electro-spinning. The uncoated and coated composite fabricated membranes were characterized using contact angle, liquid entry pressure of water, and scanning electron microscopy. The membranes were further tested for 6 h desalination by direct contact membrane distillation (DCMD) and vacuum membrane distillation (VMD), with a 3.5 wt.% synthetic NaClaq as the feed. In DCMD the feed liquid and permeate side temperature were maintained at 27.5 °C and 15 °C, respectively. For VMD, the feed liquid temperature was 27 °C and a vacuum of 94.8 kPa was applied on the permeate side. The maximum permeate flux achieved was 3.2 kg/m(2).h for VMD and 6.5 kg/m(2).h for DCMD. The salt rejection obtained was higher than 99.98%. The coated membranes showed a more stable flux than the uncoated membranes indicating that the double layered membranes have great potential in solving the pore wetting problem in MD. PMID:26630042

  6. Mapping a candidate gene (MdMYB10 for red flesh and foliage colour in apple

    Full Text Available Abstract Background Integrating plant genomics and classical breeding is a challenge for both plant breeders and molecular biologists. Marker-assisted selection (MAS is a tool that can be used to accelerate the development of novel apple varieties such as cultivars that have fruit with anthocyanin through to the core. In addition, determining the inheritance of novel alleles, such as the one responsible for red flesh, adds to our understanding of allelic variation. Our goal was to map candidate anthocyanin biosynthetic and regulatory genes in a population segregating for the red flesh phenotypes. Results We have identified the Rni locus, a major genetic determinant of the red foliage and red colour in the core of apple fruit. In a population segregating for the red flesh and foliage phenotype we have determined the inheritance of the Rni locus and DNA polymorphisms of candidate anthocyanin biosynthetic and regulatory genes. Simple Sequence Repeats (SSRs and Single Nucleotide Polymorphisms (SNPs in the candidate genes were also located on an apple genetic map. We have shown that the MdMYB10 gene co-segregates with the Rni locus and is on Linkage Group (LG 09 of the apple genome. Conclusion We have performed candidate gene mapping in a fruit tree crop and have provided genetic evidence that red colouration in the fruit core as well as red foliage are both controlled by a single locus named Rni. We have shown that the transcription factor MdMYB10 may be the gene underlying Rni as there were no recombinants between the marker for this gene and the red phenotype in a population of 516 individuals. Associating markers derived from candidate genes with a desirable phenotypic trait has demonstrated the application of genomic tools in a breeding programme of a horticultural crop species.

    Suppression subtractive hybridization (SSH) was employed to identify candidate genes involved in red coloration in apple peel with the ultraviolet (UV)-B-treated 'Mutsu'. After reverse Northern blotting verification, nearly 80 clones were successfully sequenced. Large portions of the expressed sequence tags (ESTs) are well characterized anthocyanin biosynthesis-related genes, such as chalcone synthase (11A5), flavonol synthase (12F3), anthocyanidin synthase (11H5) and UDP-glycosyl transferase (14A12) whose presence proved the success of SSH. Eight ESTs were selected for quantitative real-time polymerase chain reaction analysis and their expressions were all elevated in 'Induction', further confirming the reliability of the SSH library. One EST, 11F4 (CONSTITUTIVE PHOTOMORPHOGENIC 1: COP1) with putative function in light signal relay was further analyzed in 'Mutsu' and 'Tsugaru', along with MdHY5 (ELONGATED HYPOCOTYL 5: the downstream target of COP1), MdMYB22 (a possible flavonol-specific activator under the regulation of HY5, belonging to the SG7/PRODUCTION OF FLAVONOL GLYCOSIDES family) and MdMYBA. Results showed that MdCOP1, MdHY5, MdMYB22 and MdMYBA were all UV-B inducible genes and anthocyanin accumulation occurred after their increased expressions. Moreover, their expressions and anthocyanin content were enhanced under UV-B plus 17°C treatment. The presence of G box, a known consensus binding site of HY5, in the MdMYBA promoter region implicated that it could be regulated by MdHY5, which was verified by the result of the yeast one-hybrid analysis. Our data suggested that UV-B irradiation would induce the utmost upstream light signaling factor, MdCOP1, which activates MdHY5 signaling by binding to the promoter regions of MdMYBs, and finally leads to the red coloration of apple peels.

  13. Design and Implementation of a Non-pipelined MD5 Hardware Architecture Using a New Functional Description

    Science.gov (United States)

    Algredo-Badillo, Ignacio; Feregrino-Uribe, Claudia; Cumplido, René; Morales-Sandoval, Miguel

    MD5 is a cryptographic algorithm used for authentication. When implemented in hardware, the performance is affected by the data dependency of the iterative compression function. In this paper, a new functional description is proposed with the aim of achieving higher throughput by mean of reducing the critical path and latency. This description can be used in similar structures of other hash algorithms, such as SHA-1, SHA-2 and RIPEMD-160, which have comparable data dependence. The proposed MD5 hardware architecture achieves a high throughput/area ratio, results of implementation in an FPGA are presented and discussed, as well as comparisons against related works.

    The main aim of the MD was to study the dependency of bunch-by-bunch intensity measurements to beam position and bunch length variations. Large beam position offsets in IR4 and varying bunch length were introduced to compare the performance of the presently installed Fast Beam Current Transformers with the new Integrating Current Transformer and the new Wall Current Transformer. This note explains all the procedures of the LHC MD 398, which took place on 20/07/2015, and presents the obtained results.

    SERCH is one of seven regional Broker/Facilitator programs funded by NASA's Space Science Mission Directorate. Our purpose is to promote space science awareness and to enhance interest in science, math, and technology through the use of NASA's mission data, information, and educational products. We work closely with educators and NASA-funded scientists in 14 states (AL, AR, DC, FL, GA, KY, LA, MD, MS, NC, PR, SC/VI, TN, and VA) throughout the southeastern U.S. to share what NASA is doing in space science. Every year SERCH dedicates money from its budget to support education/outreach initiatives that increase the awareness and understanding of the four major scientific themes, or forums from NASA's space science program: 1) Sun-Earth Connection, 2) Solar System Exploration, 3) Structure and Evolution of the Universe, and 4) Astronomical Search for Origins and Planetary Systems. SERCH is particularly interested in proposals for education/outreach efforts that establish strong and lasting partnerships between the space science and education communities and that support the NASA's education mission. We encourage innovative, inter-disciplinary teams involving both scientists and educators to apply. These peer-reviewed grants are awarded for a period of one year in amounts usually ranging from 5,000 to 10,000. Three examples of highly successful previous grant awards include: 1) Teaching Astronomy and Space Science in Kentucky (KY): Designed to improve knowledge of science core concepts and teaching skills in astronomy and space science and increased expertise in achieving current Kentucky academic expectations; 2) Development of Multi-media Space Science Education/Tutorial Modules (MD): The objective is the production of three "turn-key" internet-based multi-media student tutorial modules to enable the mostly part-time professors/instructors teaching introductory astronomy in community colleges to add exciting and cutting-edge topics to their existing astronomy courses

    Charles Morehead studied medicine in Edinburgh and Paris. Among his teachers were George Jardine (1742-1827) (moral philosophy), Professor William Pulteney Alison (1790-1859) (medicine), Pierre Louis (1787-1872) and René Laennec (1781-1826). He joined as Assistant Surgeon in the Bombay Medical Service of the East India Company and was appointed to the staff of Governor Sir Robert Grant (1779-1838). Grant and Morehead founded the Grant Medical College and Sir Jamsetjee Jejeebhoy (1811-1877) Hospital in Bombay. Morehead established standards of medical education at these institutions far superior to those in Calcutta and Madras and, in some ways, to those in Britain. His emphasis on discipline, regular attendance, learning medicine at the bedside, the maintenance of detailed records on all patients and thorough evaluation of the progress made by students were salutary. While in London to recover his health, he wrote his classic book Clinical Researches on Disease in India for Indian doctors and those from Britain entering the Indian Medical Services. He lived in Edinburgh after retirement from India but continued to help teachers and students at his institutions in Bombay. PMID:24585609

The predicted IOL powers of the Ocular MD SRK/T, Ocular MD Haigis, and ASCRS averages were compared. The Ocular MD average (composed of an average of Ocular MD SRK/T and Ocular MD Haigis and the all calculator average (composed of an average of Ocular MD SRK/T, Ocular MD Haigis, and ASCRS were also compared. Primary outcome measures were mean arithmetic and absolute IOL prediction error, variance in mean arithmetic IOL prediction error, and the percentage of eyes within ±0.50 and ±1.00 D.Results: The Ocular MD SRK/T and Ocular MD Haigis averages produced mean arithmetic IOL prediction errors of 0.57 and –0.61 diopters (D, respectively, which were significantly larger than errors from the ASCRS, Ocular MD, and all calculator averages (0.11, –0.02, and 0.02 D, respectively, all P < 0.05. There was no statistically significant difference between the methods in absolute IOL prediction error, variance, or the percentage of eyes with outcomes within ±0.50 and ±1.00 D.Conclusion: The ASCRS average was more accurate in predicting IOL power than the Ocular MD SRK/T and Ocular MD Haigis averages alone. Our methods using combinations of these averages which, when compared with the individual averages, showed a trend of decreased mean arithmetic IOL
